Description

The utility model relates to the woodworking industry, in particular to the production of wood briquettes, and can be used in devices for the manufacture of briquettes from crushed wood.

A device for the manufacture of wood briquettes from crushed wood with an open pressing chamber, including dies for the pressed mass, a mechanism for creating a pressing force, a dispenser, a conveyor for collecting finished briquettes and a drive. (N.A. Modlin, A.N. Eroshkin, Briquetting of shredded wood and bark, M., Forest industry, 1971, p. 36-37).

A disadvantage of the known device is the limitation on the final density of the pressed material. This is due to the small amount of backing of the pressed mass in short open dies. When lengthening the open matrix, in order to create a significant back pressure, the processed material is stuck in the press channel.

Also known is a device for the manufacture of wood briquettes from crushed wood with a closed pressing chamber, which includes dies for the pressed mass, a mechanism for creating a pressing force, a dispenser, a conveyor for collecting finished briquettes and a drive. (N.A. Modlin, A.N. Eroshkin, Briquetting of shredded wood and bark, M., Forestry, 1971, S. 36-37 - prototype).

The disadvantages of the prototype are low productivity due to the need for soaking under pressure each portion of the chopped wood materials for 20-30 s and the complexity of the process of extracting the finished briquette from the closed matrix.

The technical task of the utility model is to increase the efficiency of the device by increasing its productivity, increasing the density of manufactured wood briquettes and simplifying the extraction of finished briquettes from the device.

The technical problem is achieved in that in a device for the manufacture of wood briquettes, including dies for pressed mass, a mechanism for creating a pressing force, a batcher, a conveyor for collecting finished briquettes and a drive, the matrices are located on a rotary platform, at the bottom of which a retaining plate is fixedly fixed, having landing hole for removing finished briquettes, the mechanism for creating the pressing force is made in the form of a group of punches rigidly mounted on one plate, the lengths of which are sequentially increased I am in the direction of the landing hole.

The utility model has the following differences from the prototype:

- matrices are located on a rotary platform;

- at the bottom of the turntable the retaining plate is fixedly fixed, having an upset hole for removing finished briquettes;

- the mechanism for creating the pressing force is made in the form of a group of punches rigidly mounted on one plate, the lengths of which are sequentially increased in the direction of the landing hole.

The arrangement of the matrices on the rotary platform allows increasing their number, supplying the device with a retaining plate and implementing a mechanism for creating a pressing force in the form of a group of punches of different successively increasing lengths, which makes it possible to increase the density of manufactured briquettes, to press without holding the pressed mass in the device, and makes it possible to increase the length of the matrices while ensuring high density briquettes and simplify the planting of finished briquettes through the longest punch.

This will improve the efficiency of the device by increasing its productivity, increasing the density of manufactured wood briquettes and simplifying the extraction of finished briquettes from the device.

In the patent information fund we reviewed, no similar technical solutions were found with the indicated set of features.

The device is applicable and will be used in the industry in 2010.

Figure 1 shows a diagram of a device for the manufacture of wood briquettes, front view;

Figure 2 is the same, a top view;

In Fig.3 - the same mechanism for creating a pressing force, a section along aa.

A device for the manufacture of wood briquettes includes a matrix 1 for the pressed mass 2, a mechanism 3 for creating a pressing force, a dispenser 4, a conveyor 5 for collecting finished briquettes 6 and a drive (not shown in Fig.), The Matrices 1 are located on a rotary platform 7, on the bottom 8 of which the retaining plate 9 is fixedly fixed, having an upset hole 10 for removing finished briquettes 6, the pressing force generating mechanism 3 is made in the form of a group of 12 punches 13, 14 and 15 rigidly mounted on one plate 11, the lengths of which are sequentially increasing in the direction of the landing hole 10.

The device operates as follows.

Shredded wood materials, for example, sawdust, are loaded into the batcher 4. The device drive is turned on, and the platform 8 rotates by an angle, the value of which is determined by the number of matrices 1 mounted on the platform 8 and stops, while the group of 12 punches goes down and each of the punches makes hit a portion of sawdust in the matrices, compacting them. The retaining plate 9 during the impact period carries out the support of the sawdust, which ensures the production of briquettes with the required high density. After the strike, the plate 11 with a group of 12 punches 13, 14 and 15 rises to its original position, the platform 8 is again rotated at the angle set in the device. The process of compaction of the pressed mass in each of the dies 1 is carried out sequentially by three punches.

The length of the first punch 13 (the shortest) only pre-presses the pressed mass i.e. partial compaction of the pressed mass. The length of the middle punch 14 increases the degree of compaction of the pressed mass, and the length of the long punch 15 is equal to or more than the length of the matrix, therefore, it is upsetting, i.e. carries out the landing of the finished briquette from the matrix 1 on the conveyor 5 to collect finished briquettes 6.

Thus, with each rotation of the platform 8, the pressed mass is constantly sequentially compacted in all matrices 1 of the device, depending on the punch that is in contact with it at that time and the planting of the finished briquette from one of the matrices.

The utility model allows to increase the efficiency of the device by increasing its productivity, increasing the density of manufactured wood briquettes and simplifying the extraction of finished briquettes from the device.
