Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening devices, in particular to a granulator which is convenient for discharging and screening. Background Art
[0002] The pellet mill for biomass pellet fuel is a kind of equipment used to process biomass raw materials such as sawdust, straw, peanut shells, etc. into pellets. Its operation process mainly includes raw material processing, crushing, pressing, cooling and other stages. The pellet mill is usually composed of the following main structures: 1. Feeding system; 2. Crushing system; 3. Pressing system; 4. Cooling system; 5. Conveying system, etc.; 6. Control system, etc.
[0003] The pressing system includes devices such as a press and a screener. The press will press the crushed raw materials into granular objects, and then send them to the screener for screening to the required size. The screening machine currently used has a simple structure. When screening granular objects, although particles larger than the aperture size can be screened out, smaller particles will also be screened out along with the particles of the required size. The fine particles screened out will affect the later combustion effect. Utility Model Content
[0004] The utility model aims to provide a granulator which is convenient for discharging and screening materials, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a granulator that is convenient for discharging and screening, comprising a box body and a first screening device body, the granulator body is fixed to the top end of the box body, first clamps are arranged on both sides of the middle of the box body, the interior of the first clamp is connected to the first screening device body through a first buffer, a sieve plate is arranged inside the first screening device body, sieve holes are opened through the middle of the sieve plate, second clamps are arranged on both sides of the bottom end of the box body, and the interior of the second clamp is connected to the second screening device body through a second buffer.
[0006] When using a granulator that is convenient for discharging and screening in the technical solution, the staff must first connect the utility model to an external power supply, control the operation of the utility model through the control panel, and the staff pours the granulated raw materials into the interior of the feed hopper, and the raw materials will enter the interior of the granulator body through the feed hopper, and the granulator body will granulate the raw materials. After the raw materials are made into granules, they will fall onto the surface of the sieve plate in the main body of the first screening device, and the vibration motor will run at this time, and the vibration motor will vibrate with the sieve plate. After the sieve plate vibrates, the raw materials on its surface that meet the aperture of the sieve hole will be screened by the sieve hole, and the raw materials that are not screened will fall from the leak to the interior of the first discharge hopper due to the vibration of the sieve plate, and then be discharged to the outside of the box through the first discharge hopper. The raw materials can be recycled into the granulator body to the required size for re-granulation, and the raw materials screened through the sieve holes will fall onto the surface of the second screening device body. The second screening device body has the same internal structure as the first screening device body and operates in the same way, that is, the sieve holes opened in the second screening device body are smaller in diameter than the sieve holes opened in the first screening device body, because the sieve holes in the first screening device body can screen out raw materials larger than the required size, while the sieve holes in the second screening device body can screen out raw materials smaller than the required size. The raw materials smaller than the required size will be screened out through the third discharge hopper, and the raw materials that meet the size will eventually remain on the sieve plate surface in the second screening device body and be discharged through the second discharge hopper.
[0007] Preferably, a leak is formed through one end of the sieve plate, so that particles falling onto the surface of the sieve plate and not screened by the sieve holes can pass through the leak and fall into the first and second discharge hoppers after vibration screening.
[0008] Preferably, side plates are provided on both sides of the top surface of the sieve plate, and a vibration motor is provided in the middle of the bottom surface of the sieve plate. The installation of the side plates blocks particles falling onto the surface of the sieve plate, preventing them from falling through the two sides of the sieve plate, while the installation of the vibration motor allows the sieve plate to vibrate, achieving the effect of power output.
[0009] Preferably, the internal structure of the second screening device body is the same as the internal structure of the first screening device body. Through the cooperation of the first screening device body and the second screening device body, the particles produced by the granulator body can be screened for the required size, achieving the effect of screening out particles larger than the required size and particles smaller than the required size.
[0010] Preferably, a first discharge hopper is installed through one side of the outer part of the box, and a second discharge hopper is installed through the other side of the outer part of the box. Through the cooperation of the first discharge hopper and the second discharge hopper, particles that are not screened by the first screening device body and the second screening device body can be discharged through the two places respectively, achieving the effect of discharging materials outward.
[0011] Preferably, a feeding hopper is connected in the middle of the top surface of the box body. The installation of the feeding hopper allows the raw materials to be processed to be sent into the box body for granulation and screening, and provides a feeding position.
[0012] Preferably, a third discharge hopper is provided in the middle of the bottom surface of the box, and legs are connected to the four sides of the bottom surface of the box. The installation of the third discharge hopper allows the particles screened by the screen plate in the second screening device body to be discharged to the outside of the box through the third discharge hopper, and the installation of the legs allows the utility model to be stably placed off the ground for use.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model installs the pelletizer body and the screening device together inside the box body, forming an upper and lower structure, which has continuity when in use and also reduces the space occupied. After the internal pelletizing, it will be screened by the screening devices with two aperture sizes. The two screening devices will screen out the particles larger and smaller than the required size, so as to ensure that the size of the screened particles is correct, improve the quality and calorific value of the biomass particles, and make them more suitable for use as fuel.
