Drawings of a screw press for sawdust

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

Features of the design of the press

Pressing equipment for the manufacture of fuel briquettes is a mechanical device that consists of the following elements:

1. Base - usually represented by a table, which 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 main form.
3. Power frame. This piece of equipment is attached to the base. Its main task is to transfer force to a compressible raw material, which is carried out through a punch.
4. Drive unit. Depending on the type of screw press for sawdust, a mechanical or manual type of exposure can be used:
   • For the equipment of the manual drive, an additional lever is used, with the help of which the user's force is transmitted.
   • Mechanical - hydraulic booster or electric motor.

Principle of operation

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

1. The raw material is poured into a matrix designed for this purpose and compacted.

Important! Try to load the equipment with the maximum possible amount of raw materials.

2. With the help of a system of levers, the main force is transmitted to the punch.
3. This structural element compresses the loaded raw materials, forming a dense briquette from it.
4. The mold must be unlocked and the fuel material sent to dry.

Important! As a raw material for this device can be used materials such as chips, sawdust, paper waste, seed cleaning and nutshells.

Do-it-yourself screw press for sawdust

If you need to make fuel briquettes for personal use and in small volumes, then the rational solution is to make a screw press with your own hands. If you have design experience or technical education, then independently perform a graphic image of the device is not difficult. If you are not confident in your own abilities, then you can use one of the professional drawings.

Kinds

The most popular models of homemade screw presses are devices of the following types:

1. Lever The basis of such an installation is a lever, with the help of which physical force is transferred to the raw materials 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.

Necessary materials

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

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

Instrument manufacturing process

Directly manufacturing a screw press for sawdust must be performed according to the following instructions:

1. Carefully study the existing drawing of the future device for creating solid fuel briquettes.
2. Do some work on preparing the elements of the future press. At this stage of production, semi-finished processing of parts should be performed and the necessary holes should be made.
3. Final assembly of the device. To save own forces and time, it is recommended to carry out this stage of work as quickly as possible to the future place of use.
4. Perform commissioning, for which create several briquettes using 40-60% of the raw material from the maximum possible design characteristic.

The advantages and disadvantages of homemade fuel briquettes

The most rational will be the manufacture of a screw press for sawdust if you have your own wood production or the opportunity to purchase waste at a bargain price. However, it should be borne in mind that despite the low cost of such fuel, it still has a number of disadvantages:

1. After drying, homemade briquettes are light enough, due to their low density.
2. The specific heat from the combustion of such materials is three times lower than when using wood.
3. The process of independent production of fuel briquettes takes a fairly large amount of time and requires considerable effort.
4. Due to the need to create large fuel reserves, their storage is difficult, because it is necessary to prevent the briquettes from getting wet.

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