How to make a press for briquettes with your own hands

Vegetable litter by type of agricultural waste, leaves and sawdust is an excellent fuel. However, if you want to use all this in conjunction with a conventional boiler, you must first prepare the pressed briquettes. If the fuel does not have a certain shape, it will need to be thrown every 5 minutes, and most of it will fall through the grate.

Buy or make

Press for briquettes can be purchased at a store of the corresponding equipment, however, such a device is quite expensive. In addition, such an acquisition will be profitable only if you plan to organize a permanent production. If you own a country house or private housing in the city, you can build such a device yourself.

Recommendations for the manufacture of the press

The purchase of factory equipment for the production of briquettes will cost in the amount of 300 thousand to 1 million rubles, the price will depend on the capacity of the unit. A private consumer, who only needs to use fuel briquettes from time to time , will not be able to afford such equipment. It is much easier to make a press from improvised materials, especially since in this design there is nothing complicated.

Some craftsmen use ready-made mechanisms, while others collect the device from scratch. If you decide to use the latest solution, the press for briquettes can be made from a lever and a screw mechanism. On the lever you will be able to work with your own weight. This design is made of wood, but for the screw solution you will need a lathe and steel workpieces. The auger extruder can be made independently, however, such an undertaking is expensive, because in work it is necessary to use special high-quality steel.

Using a ready-made mechanism

Press for briquettes can be made and on the basis of the finished mechanism. To do this, you can use a hydraulic press or a jack. The master will only have to supplement this node with a matrix and a punch. Any self-made device for pressing sawdust is not able to provide lignin. In return, you will have to add third-party binders. For this approach:

• Cheap wallpaper paste;
• Soggy paper;
• clay.

Clay should be added in the volume of 1 part for 10 parts of sawdust. If it is a question of soggy paper, then for this, a corrugated cardboard is used, in which lignin is contained.

Methods of work

If you decide to make a press for briquettes on the basis of a screw and lever mechanism, know: there is no need to use purchased nodes. However, they will not have a high compression force. That's why the press can be created on the basis of a hydraulic jack, equipped with an electric motor or a manual drive.

A punch is attached to the hydraulic unit, the dimensions of which must correspond to the dimensions of the matrix, and it will be formed into briquettes in it. The matrix can be made of a thick-walled tube, which will be the simplest option. In order to allow moisture and air to escape, holes must be made in the walls of the pipe. The matrix must have a removable bottom. If it is removed, the finished briquet can be pushed out with a punch in the tray. The finished mechanism should be supplemented with two handles, which will ensure the convenience of transportation.

Preparation of materials

The press for briquettes can be made from steel sheet and corner. The angle should be equal to the side with a side of 100 mm. The steel sheet should have a thickness of 3 to 6 mm, from which it is necessary to cut the punch. The diameter of the matrix determines the thickness of the workpiece. From this sheet you need to perform a removable bottom.

Preparation of the main nodes

The press for briquettes can be made from pipes and galvanized steel. The pipe should have a diameter in the range from 25 to 30 mm, from it cut out the punch rod. The blank for the matrix should be made of a thick-walled pipe, the diameter of which will depend on the size of the briquettes.

If the briquettes turn out to be thin, then their density will increase, and the productivity of the machine, on the contrary, will decrease. For the mixer body, a pipe of impressive diameter is suitable, and if it is not found, it can be made from a sheet of iron. When a press for fuel briquettes is produced (with one's own hands), two trays should be made, one of which will be used for receiving finished products, while the other will be used to load the prepared material.

Assembly Instructions

Channel bars will go to the base of the device, while from the corner you should make 4 racks, each of which will be 1.5 m long. They are installed and fastened vertically, the distance between them should be the same. In the next step, a drum, which is necessary for mixing, should be made from a sheet of iron or a finished pipe.

If you have a failed washing machine, the drum can be borrowed from it. This element is fixed to the posts. If necessary, it can be supplemented with an electric motor. If the motor was too high-speed, it is necessary to use the gearbox, because sometimes it is not possible to reduce the speed of rotation to the desired value due to the difference in the diameters of the pulleys.

And we continue to collect a press for fuel briquettes with our own hands. In the next step, the tray is fixed under the drum, along which the material will enter the matrix. Holes, whose diameter is from 3 to 5 mm, should be made in the walls of the pipe, used as a blank for the matrix. They are distributed as evenly as possible. The matrix should be fixed to the flange, to which the removable bottom is fixed. It should be made of steel sheet, giving the appearance of a disk with eyelets.

When a press for briquettes from sawdust is made, it is necessary to follow the technology. After reading it, you can understand that the matrix should be strengthened under the loading tray to the base, and this can be done using a mechanical fastener or welding machine. From the steel sheet should be cut round punch, the diameter of which will allow the element to enter the matrix. To produce the stem, a 30 mm tube is needed, to which one side is welded a punch, while the other end is attached to a hydraulic installation.

Features of screw press manufacturing

The screw press for making fuel briquettes with their own hands can also be made, but the work will be more complicated. With this mechanism it will be possible to provide an extrusion method for manufacturing briquettes, which is often considered in the case of a domestic meat grinder or juicer.

For the operation of such equipment, the raw material will need to be placed in a receiving hopper from which it will be transported by a screw into a tapered conical channel. At this stage, there is compression, and the screw press will develop a very high effort. As a result, you can get real firewood from sawdust, which will have the appearance of a hexagon. In the process, they undergo heat treatment and are cut with a special knife.

In order to better understand the structure of this mechanism, you should look at the drawing, which is presented in the article. Even if you use a hydraulic jack in a homemade press, you will not be able to create an effort greater than 300 bar. Therefore, it is necessary to abandon the factory technology, where water is not used. This is due to the fact that without the binding components of the briquettes will not be obtained. As practice shows, a screw press for briquettes from sawdust with own hands is most difficult to make. The reasons are banal. It is not so easy to manufacture parts independently, and the costs of production will be high. For the case it is necessary to take high quality steel, the electric drive is also useful. This design requires an engine with a minimum output of 7 kW. Then it's up to the little one: you just have to put it all together, using the drawing.

Conclusion

Press for briquettes from churn is manufactured using the same technology that was described above, when the drum is based on the washing machine. In this case, the difference will consist only in the fact that the spring should be welded to the bottom of the matrix with a disc of the same diameter as the punch. This will improve the efficiency of the equipment, because the extraction of briquettes will take less time.
