Abstract
Description
Technical Field
[0001] This utility model relates to the field of pellet mill technology, and in particular to a compact biomass pellet mill. Background Technology
[0002] A biomass pellet machine is a biomass energy pretreatment equipment that mainly uses agricultural and forestry processing waste such as wood chips and straw as raw materials to solidify them into high-density pellet fuel. Compact biomass pellet machines, also known as small biomass pellet machines, occupy less space and are more flexible in use.
[0003] When biomass materials such as sawdust and straw are fed into the feed hopper of a biomass pellet mill, these materials can easily accumulate and clog the bottom of the feed hopper. This prevents the material at the top of the feed hopper from entering the processing chamber for pelleting, thus reducing the processing speed of the biomass pellet mill. Utility Model Content
[0004] This utility model proposes a compact biomass pellet mill to solve the problem that material accumulation can clog the bottom of the feed hopper of a biomass pellet mill, preventing the material at the top of the feed hopper from entering the processing chamber for pelleting and thus reducing the processing speed of the biomass pellet mill.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a compact biomass pellet mill, including a base plate, a drive mechanism is provided on one side of the top of the base plate, a processing chamber is provided on one side of the top of the drive mechanism, a feed hopper is fixedly installed on the top of the processing chamber, a discharge hopper is fixedly installed on the bottom of the outer surface of the processing chamber, and an auxiliary device is provided on the outer surface of the processing chamber. The auxiliary device strikes the processing chamber with two striking plates, causing the processing chamber and the feed hopper to vibrate to promote the entry of material into the processing chamber.
[0006] The effect achieved by the above components is as follows: by setting two striking plates that move towards each other, the two striking plates strike the processing chamber, which causes the processing chamber and the feed hopper connected to the processing chamber to vibrate. This helps the material to enter the processing chamber through the feed hopper, prevents the material from clogging the feed hopper, and helps to improve the processing rate of the biomass pellet machine.
[0007] Preferably, the auxiliary device includes two striking plates symmetrically arranged on the outer surface of the processing chamber. The sides of the two striking plates that are close to each other are arc-shaped. A first L-shaped plate is symmetrically fixedly installed on the top of the outer surface of the processing chamber. A rectangular rod is slidably installed on the inner wall of the first L-shaped plate. A mounting plate is fixedly installed on one end of the rectangular rod. The mounting plate is fixedly installed on the other side of the striking plate through a disassembly assembly. A second L-shaped plate is fixedly installed on the other end of the rectangular rod. One end of the second L-shaped plate is inclined. The same trapezoidal block is slidably installed on the inclined surfaces of the two second L-shaped plates. An electric telescopic rod is fixedly installed on the top of the driving mechanism. One end of the electric telescopic rod is fixedly installed on the bottom of the trapezoidal block.
[0008] The effect achieved by the above components is as follows: when the electric telescopic rod is activated, it will drive the trapezoidal block to move vertically. When the trapezoidal block moves upward, it will push the two second L-shaped plates, causing them to move away from each other. The second L-shaped plates will drive the striking plates connected to the rectangular rod to move synchronously, causing the two striking plates to move away from the processing chamber at the same time. Similarly, the electric telescopic rod will drive the two striking plates to move towards each other, causing them to hit the processing chamber. This will cause the feed hopper to vibrate, which can help the material enter the processing chamber through the feed hopper.
[0009] Preferably, a spring is fitted on the outer surface of the rectangular rod, and the two ends of the spring are respectively fixedly installed on one side of the mounting plate and the first L-shaped plate.
[0010] The effect achieved by the above components is as follows: by setting the spring, when the two striking plates move away from each other, the spring will be compressed, causing the spring to deform. When the two striking plates move closer to each other, the spring will return to its original position and push the striking plates, which helps to ensure that the striking plates can cause the feed hopper to vibrate when striking the processing chamber.
[0011] Preferably, a rubber plate is adhered to the side of each of the two striking plates that are close to each other.
[0012] The effect achieved by the above-mentioned components is that by setting up a rubber plate, one side of the rubber plate can be replaced by the striking plate and abut against the outer surface of the processing chamber, thereby reducing the damage to the processing chamber caused by the striking plate when striking the processing chamber.
[0013] Preferably, the same reinforcing block is fixedly installed on the two adjacent sides of the second L-shaped plate. The horizontal cross-section of the reinforcing block is triangular. The second L-shaped plate mainly bears the reaction force generated by the impact of the striking plate on the processing chamber.
[0014] The effect achieved by the above components is as follows: by setting up triangular reinforcing blocks, the stability of the second L-shaped plate is enhanced by utilizing the stability of triangles.
[0015] Preferably, the disassembly and assembly assembly includes two slot blocks, one side of which is symmetrically fixedly installed on both sides of the mounting plate. Threaded pins are inserted into the inner wall of each slot block, one end of which is fixedly installed on one side of the striking plate, and a nut is threaded onto the outer surface of the threaded pin.
[0016] The effect achieved by the above components is as follows: by inserting the threaded pin into the inner wall of the slot block and then rotating the nut so that one side of the nut is in contact with one side of the slot block, the mounting plate and the striking plate can be fixed, which also makes it easier to disassemble the striking plate and make it easier to maintain and replace the striking plate separately.
[0017] Preferably, a limiting plate is symmetrically fixedly installed on one side of the striking plate, and the outer surface of the slot block is inserted into the inner wall of the limiting plate.
[0018] The effect achieved by the above components is as follows: by setting the limiting plate, it is easy to quickly position the mounting plate and the slot block. At the same time, the limiting plate can assist in fixing the slot block and improve the stability of fixing the striking plate.
[0019] Preferably, a circular block is fixedly installed at one end of the threaded pin, and the outer diameter of the circular block is larger than the outer diameter of the threaded pin.
[0020] The effect achieved by the above components is that by setting up a round block, the round block can block one end of the threaded pin, which helps to prevent the nut from easily coming off the threaded pin.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, two striking plates are set up and move towards each other, causing the two striking plates to strike the processing chamber. This causes the processing chamber and the feed hopper connected to the processing chamber to vibrate, which helps the material to enter the processing chamber through the feed hopper, prevents the material from clogging the feed hopper, and helps to improve the processing rate of the biomass pellet machine.

[0028] Example 1, referring to Figures 1-4 As shown, this embodiment discloses a compact biomass pellet mill, including a base plate 1. A drive mechanism 2 is provided on one side of the top of the base plate 1, and a processing chamber 3 is provided on one side of the top of the drive mechanism 2. (Materials enter the interior of the processing chamber 3 through a feed hopper. The interior of the processing chamber 3 is equipped with a pressure roller and a ring die. The drive mechanism 2 can be a diesel engine, which is connected to the pressure roller inside the processing chamber through a reducer, thereby driving the pressure roller to rotate. Through the squeezing action of the pressure roller and the ring die, the material is extruded from the small holes of the die to form cylindrical or rod-shaped pellet fuel. This process does not require the addition of any binder; the lignin in the raw material naturally acts as a binder under high temperature and pressure. All of the above belong to the conventional prior art of biomass pellet mills.) (The technique is not elaborated here.) A feed hopper 4 is fixedly installed on the top of the processing chamber 3, and a discharge hopper 5 is fixedly installed on the bottom of the outer surface of the processing chamber 3. An auxiliary device 6 is provided on the outer surface of the processing chamber 3. The auxiliary device 6 strikes the processing chamber 3 with two striking plates 64, causing the processing chamber 3 and the feed hopper 4 to vibrate, thereby promoting the material to enter the processing chamber 3. By setting two striking plates 64, the two striking plates 64 move towards each other, causing the two striking plates 64 to strike the processing chamber 3. This will cause the processing chamber 3 and the feed hopper 4 connected to the processing chamber 3 to vibrate, which can help the material to enter the processing chamber 3 through the feed hopper 4, prevent the material from clogging the feed hopper 4, and help improve the processing rate of the biomass pellet machine.
[0029] Reference Figures 2-4As shown, the auxiliary device 6 includes two striking plates 64, which are symmetrically arranged on the outer surface of the processing chamber 3. The sides of the two striking plates 64 that are close to each other are arc-shaped. A first L-shaped plate 61 is symmetrically fixedly installed on the top of the outer surface of the processing chamber 3. A rectangular rod 62 is slidably installed on the inner wall of the first L-shaped plate 61. A mounting plate 63 is fixedly installed on one end of the rectangular rod 62. The mounting plate 63 is fixedly installed on the other side of the striking plate 64 through the disassembly assembly 7. A second L-shaped plate 65 is fixedly installed on the other end of the rectangular rod 62. One end of the second L-shaped plate 65 is inclined. The same trapezoidal block 66 is slidably installed on the inclined surfaces of the two second L-shaped plates 65. An electric telescopic rod 67 is fixedly installed on the top of the drive mechanism 2. One end of the electric telescopic rod 67 is fixedly installed on the bottom of the trapezoidal block 66. When the electric telescopic rod 67 is activated, it will drive the trapezoidal block 66 to move vertically. When the trapezoidal block 66 moves upward, it will push the two second L-shaped plates... The two L-shaped plates 65 are pushed away from each other by the push rod 65. The L-shaped plates 65 will drive the striking plates 64 connected to the rectangular rod 62 to move synchronously, so that the two striking plates 64 move away from the processing chamber 3 at the same time. Similarly, the two striking plates 64 are driven to move towards each other by the electric telescopic rod 67, so that the two striking plates 64 hit the processing chamber 3. This will cause the feed hopper 4 to vibrate, which can help the material enter the processing chamber 3 through the feed hopper 4. The outer surface of the rectangular rod 62 is fitted with a spring 68. The two ends of the spring 68 are respectively fixedly installed on one side of the mounting plate 63 and the first L-shaped plate 61. By setting the spring 68, when the two striking plates 64 move away from each other, they will compress the spring 68, causing the spring 68 to deform. When the two striking plates 64 move closer to each other, the spring 68 will return to its original position and push the striking plates 64, which helps to ensure that the striking plates 64 can cause the feed hopper 4 to vibrate when they hit the processing chamber 3.
[0030] Reference Figure 2 and Figure 3 As shown, rubber plates 69 are glued to the sides of the two striking plates 64 that are close to each other. By setting the rubber plates 69, one side of the striking plate 64 can be replaced to abut against the outer surface of the processing chamber 3, thereby reducing the damage to the processing chamber 3 caused by the striking plate 64 when it strikes the processing chamber 3. The same reinforcing block 610 is fixedly installed on the two adjacent sides of the second L-shaped plate 65. The horizontal cross section of the reinforcing block 610 is triangular. The second L-shaped plate 65 will mainly bear the reaction force generated by the striking plate 64 hitting the processing chamber 3. By setting the triangular reinforcing block 610, the stability of the second L-shaped plate 65 is strengthened by utilizing the stability of the triangle, thereby improving the stability of the second L-shaped plate 65.
[0031] Reference Figure 2 and Figure 3As shown, the disassembly and assembly assembly 7 includes two slot blocks 71. One side of each slot block 71 is symmetrically fixedly installed on both sides of the mounting plate 63. Threaded pins 72 are inserted into the inner wall of the slot block 71. One end of each threaded pin 72 is fixedly installed on one side of the striking plate 64. A nut 73 is threaded onto the outer surface of the threaded pin 72. By inserting the threaded pin 72 into the inner wall of the slot block 71 and then rotating the nut 73, one side of the nut 73 is grounded with one side of the slot block 71, thus fixing the mounting plate 63 and the striking plate 64. This also facilitates the disassembly of the striking plate 64, making it easier to maintain and replace the striking plate 64 individually.
[0032] Reference Figure 2 and Figure 3 As shown, a limiting plate 74 is symmetrically fixedly installed on one side of the striking plate 64. The outer surface of the slot block 71 is inserted into the inner wall of the limiting plate 74. By setting the limiting plate 74, it is easy to quickly position the mounting plate 63 and the slot block 71. At the same time, the limiting plate 74 can assist in fixing the slot block 71, improving the stability of fixing the striking plate 64. A round block 75 is fixedly installed on one end of the threaded pin 72. The outer diameter of the round block 75 is larger than the outer diameter of the threaded pin 72. By setting the round block 75, the round block 75 can block one end of the threaded pin 72, which helps to prevent the nut 73 from easily disengaging from the threaded pin 72.
[0033] Working principle: Activating the electric telescopic rod 67 causes the trapezoidal block 66 to move vertically. As the trapezoidal block 66 moves upward, it pushes the two second L-shaped plates 65 away from each other. The second L-shaped plates 65 then move the striking plates 64 connected to the rectangular rod 62 synchronously, causing both striking plates 64 to move away from the processing chamber 3 simultaneously. As the striking plates 64 move away from each other, they compress the spring 68, causing it to deform. Similarly, the electric telescopic rod 67 then drives the two striking plates 64 to move towards each other. The electric telescopic rod 67 can quickly stop the two striking plates 64, and at the same time the spring 68 will reset and stretch the striking plate 64, causing the rubber plate 69 on one side of the striking plate 64 to hit the processing chamber 3. This will cause the feed hopper 4 to vibrate. Repeating the operation multiple times can help the material enter the processing chamber 3 through the feed hopper 4. Insert the threaded pin 72 into the inner wall of the slot block 71, insert the slot block 71 into the inner wall of the limiting plate 74, and then rotate the nut 73 so that one side of the nut 73 is in contact with one side of the slot block 71, which can fix the mounting plate 63 and the striking plate 64.
