Screw press drawings for sawdust

Many modern private houses are equipped with solid fuel heating systems that involve the use of coal and firewood. Such heating boilers can also work on pellets and fuel briquettes, which are made from wood waste. To increase the energy efficiency of alternative fuels, it is compressed with special equipment that can be manufactured independently. To do this, you will need quality and detailed drawings of the screw press for sawdust, which can be found in specialized books or the Internet. Let's consider step-by-step features of the device of such equipment and assembly in this article.

Design features of

press The pressing equipment for the production of fuel briquettes is a mechanical device that consists of the following elements:

1. The base is usually represented by a table that is used to attach the main structural elements of the press.
2. The matrix is ​​one of the main components of the device, which forms its basic shape.
3. Power frame. This part of the equipment is attached to the base. Its main task is to transfer the force to the compressible raw material, which is carried out through the punch.
4. Drive. Depending on the type of screw press for sawdust, the mechanical or manual impact type can be used:
   • For the hand drive equipment, an additional lever is used, with which the force of the user is transmitted.
   • Mechanical - hydraulic booster or electric motor.

How

works Before you make a sawdust press, you need to understand the basic principle of manufacturing fuel briquettes:

1. The raw material is filled with a matrix intended for this purpose and compacted.

Important! Try to load the equipment with as much raw material as possible.

1. With the help of the lever system, the main force is transferred to the punch.
2. This structural element carries out compression of the loaded raw material, forming a dense briquette from it.
3. Form must be unlocked, and the fuel material should be dried.

Important! As raw materials for this device, materials such as chips, sawdust, paper waste, seed purification and nut shells can be used.

Self-operated auger for sawdust

If you need to manufacture fuel briquettes for personal use and in small quantities, then the worm press will be a rational solution. If you have a design experience or a technical background, then it is not difficult to perform a graphic representation of the device on your own. If you are not confident in your own abilities, then you can use one of the professional drawings.

Types of

The most popular models of self-made screw presses are the following types of instruments:

1. Lever. At the heart of such an installation is the lever, through which the physical effort is transferred to the raw material loaded into the matrix.
2. Screw. Screw equipment, the working mechanism of which is driven by a screw shaft. It is equipped with a wheel and handles.

Required Materials

For the manufacture of the instrument you may need the following materials:

1. A set of tools for carpentry work, among which the main role is played by pliers, hacksaws for metal and wood, hammers, files, screwdrivers and other abrasive devices.
2. Electric drill or screwdriver.
3. Set of drills for wood and metal work.
4. The device for manual welding.
5. Wood and metal semi-finished products - boards, profiles, etc.

The manufacturing process of the

Direct manufacture of a screw press for sawdust must be carried out according to the following instructions:

1. Carefully study the existing drawing of the future device for the creation of solid fuel briquettes.
2. Carry out individual work on preparing the elements of the future press. At this stage of production, you should perform semi-finished machining of parts and make the necessary holes.
3. Carry out the final assembly of the device. To save yourself time and energy, this stage of work is recommended to be performed as quickly as possible to the future place of use.
4. Carry out the commissioning work, for which purpose create several briquettes using 40-60% of raw materials from the maximum possible design characteristic.

Advantages and disadvantages of self-made fuel briquettes

The most rational is the production of a screw press for sawdust in case you have your own wood production or the possibility of purchasing waste at a favorable price. However, it should be borne in mind that despite the low cost of such fuel, it still has a number of drawbacks:

1. After drying, homemade briquettes are light enough due to their low density.
2. Specific heat from combustion of such materials is three times lower than when using wood.
3. The process of independent production of fuel briquettes takes quite a lot of time and requires considerable effort.
4. In connection with the need to create large fuel reserves, it is difficult to store them, because you must not allow the briquettes to get wet.

Self-processing of wood waste with the help of a screw press of its own production will be rational only if there is free time and affordable raw materials. Therefore, carefully weigh all the pros and cons of such a decision before proceeding with the process of creating the equipment.
