Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a biomass pellet processing filtration device. Background Technology

[0002] A biomass pellet processing filtration device is a piece of equipment used in the biomass pellet production process to efficiently filter and purify raw materials. Its main function is to remove impurities, dust, fine particles, and impurities from the raw materials through a multi-layer filtration system, thereby ensuring the quality of the final biomass pellets produced.

[0003] However, because the feed pipe of existing filtration devices is usually fixed, the raw material cannot be evenly distributed on the surface of the filter plate when it is injected into the filtration device, and tends to concentrate at the position corresponding to the filter plate and the feed pipe. Furthermore, if larger particles in the raw material clog the filter pores of the filter plate, it will lead to material accumulation, thereby affecting the filtration efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a biomass pellet processing and filtration device, which aims to make the raw materials evenly distributed on the surface of the filter plate, reduce the probability of filter plate clogging, and improve the filtration effect.

[0005] To achieve the above objectives, this utility model proposes a biomass pellet processing and filtration device, comprising a shell and a filter plate disposed inside the shell. The top of the shell is provided with a feed pipe, and the bottom of the shell is provided with a discharge port. A corrugated hose is provided inside the shell near the feed pipe and is connected to the inside of the feed pipe. The other side of the corrugated hose is connected to a distribution pipe and is connected to the inside of the corrugated hose. The shell is provided with a drive mechanism for reciprocating the distribution pipe inside the shell. The shell is also provided with a vibration assembly for vibrating the filter plate up and down, and the vibration assembly is linked to the drive mechanism.

[0006] In one possible implementation, the drive mechanism includes a reciprocating motor, a reciprocating screw, and a moving block. One side of the distribution pipe is fixedly connected to the moving block via a connecting block. The reciprocating screw is rotatably connected to the inside of the housing. The moving block is mounted on the reciprocating screw and threadedly connected to it. The reciprocating motor is mounted on the side of the housing, and its output end is fixedly connected to the reciprocating screw.

[0007] In one possible implementation, the vibration assembly includes a squeezing block, a sliding block, and elastic elements respectively disposed at the four corners of the bottom of the filter plate. Support plates are provided inside the housing near the four corners of the bottom of the filter screen. One end of each elastic element abuts against the bottom of the filter plate, and the other end of each elastic element abuts against the surface of the corresponding support plate. The squeezing block is disposed at the bottom of the sliding block, and squeezing inclined surfaces are provided on both sides of the squeezing block. The sliding block is fixedly connected to the surface of the filter plate via a support frame, and first inclined surfaces that slidably connect with the squeezing inclined surfaces are provided on both sides of the sliding block.

[0008] In one possible implementation, a guide rod is fixedly connected to the top of each of the support plates, the filter plate is slidably connected to the guide rod, and each elastic element is sleeved on the outer surface of the guide rod.

[0009] In one possible implementation, a baffle plate is fixedly connected to the bottom of the filter plate near the support plate, and the baffle plate is inclined.

[0010] In one possible implementation, a motor mount is fixedly connected to the side of the housing, and the reciprocating motor is fixedly connected to the motor mount by bolts.

[0011] In one possible implementation, the cross-sectional area of ​​the feed tube gradually decreases from top to bottom.

[0012] This invention utilizes a corrugated flexible tube and a distribution tube connected to the inside of the feed pipe. The distribution tube reciprocates within the housing under the action of a drive mechanism, ensuring that the raw material entering the feed pipe is evenly distributed across the filter plate surface. This prevents material from concentrating at the position corresponding to the feed pipe, thereby improving the uniformity of material distribution and filtration efficiency. The vibration component is linked to the drive mechanism; as the distribution tube moves, the filter plate vibrates synchronously up and down, helping to prevent larger particles in the raw material from clogging the filter plate's pores, allowing the material to pass through the filter plate more smoothly and further improving filtration efficiency.

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] refer to Figure 1-3 This embodiment proposes a biomass pellet processing and filtration device, including a shell 1 and a filter plate 4 disposed inside the shell 1. A feed pipe 101 is provided at the top of the shell 1. The cross-sectional area of ​​the feed pipe 101 gradually decreases from top to bottom. This design can accelerate the raw material when it enters the feed pipe 101, so that the raw material can flow more smoothly to the distribution pipe 104, reducing the probability of the raw material accumulating or blocking in the feed pipe 101, and improving the efficiency and stability of feeding.

[0021] Meanwhile, the bottom of the housing 1 is provided with a discharge port 102, and a corrugated hose 103 is provided inside the housing 1 on the side near the feed pipe 101. The corrugated hose 103 is connected to the inside of the feed pipe 101, and one side of the corrugated hose 103 is fixedly connected to the feed pipe 101. The other side of the corrugated hose 103 is fixedly connected to a distribution pipe 104, and the distribution pipe 104 is connected to the inside of the corrugated hose 103. The corrugated hose 103 has the characteristics of being flexible and flexible, and can adapt to the reciprocating movement of the distribution pipe 104 under the action of the drive mechanism. At the same time, it ensures the smooth conveying of raw materials in the pipe and will not affect the feeding due to the movement of the distribution pipe 104, thus playing a connecting and transition role.

[0022] Furthermore, the housing 1 is provided with a drive mechanism for reciprocating the distribution tube 104 inside the housing 1, and the housing 1 is also provided with a vibration assembly for vibrating the filter plate 4 up and down, and the vibration assembly is linked with the drive mechanism.

[0023] When the raw material enters the housing 1 through the feed pipe 101, it passes through the feed pipe 101, the corrugated hose 103, and the distribution pipe 104 in sequence, and finally falls onto the surface of the filter plate 4. At the same time, the operator can use the drive mechanism to drive the distribution pipe 104 to move back and forth inside the housing 1, so that the raw material is evenly distributed on the surface of the filter screen and the accumulation of raw material is avoided.

[0024] In this design, the drive mechanism and the vibration component are linked, enabling the entire device to simultaneously achieve the functions of moving the distribution pipe 104 and vibrating the filter plate 4 using only a single power source, thus reducing energy waste. Compared to using two independent power sources to drive the distribution pipe 104 and the filter plate 4 separately, this linkage method utilizes energy more effectively and reduces the equipment's energy consumption.

[0025] Specifically, the drive mechanism includes a reciprocating motor 2, a reciprocating screw 201, and a moving block 202. One side of the distribution pipe 104 is fixedly connected to the moving block 202 via a connecting block 2021. The reciprocating screw 201 is rotatably connected to the inside of the housing 1. The moving block 202 is mounted on the reciprocating screw 201 and threadedly connected to it. The reciprocating motor 2 is mounted on the side of the housing 1, and its output end is fixedly connected to the reciprocating screw 201.

[0026] If necessary, the number of reciprocating lead screws 201 and moving blocks 202 can be set to two each, and they can be set on both sides of the distribution tube 104. The two reciprocating lead screws 201 can rotate synchronously through the synchronous belt pulley assembly 5, which allows both sides of the distribution tube 104 to have support, thereby improving the stability of the distribution tube 104 when it moves.

[0027] In this embodiment, the drive mechanism employs a combination of a reciprocating motor 2, a reciprocating lead screw 201, and a moving block 202. The reciprocating motor 2 provides power, and its output end is fixedly connected to the reciprocating lead screw 201, driving the lead screw 201 to rotate. The moving block 202 is threadedly connected to the reciprocating lead screw 201, allowing the moving block 202 to perform reciprocating linear motion on the lead screw 201. This, in turn, causes the moving block 202 to drive the distribution pipe 104 to reciprocate within the housing 1 via the connecting block 2021. This drive method is simple in structure, easy to implement, and can precisely control the movement of the distribution pipe 104, ensuring uniform distribution of raw materials.

[0028] In addition, a motor mount 309 can be fixedly connected to the side of the housing 1, and the reciprocating motor 2 is fixedly connected to the motor mount 309 by bolts. This installation method makes the installation of the reciprocating motor 2 more stable, ensuring that the motor will not shake or shift during operation, thereby ensuring the stable operation of the drive mechanism and the normal operation of the entire filtration device. At the same time, the bolt connection facilitates the installation and disassembly of the reciprocating motor 2, making it convenient for later maintenance and repair.

[0029] Furthermore, the vibration assembly includes a pressing block 3, a sliding block 301, and elastic elements 302 respectively disposed at the four corners of the bottom of the filter plate 4. Support plates 303 are provided inside the housing 1 near the four corners of the bottom of the filter screen. One end of each elastic element 302 abuts against the bottom of the filter plate 4, and the other end of each elastic element 302 abuts against the surface of the corresponding support plate 303. The pressing block 3 is disposed at the bottom of the moving block 202. Both sides of the pressing block 3 are provided with pressing inclined surfaces 304. The sliding block 301 is fixedly connected to the surface of the filter plate 4 through a support frame 305. Both sides of the sliding block 301 are provided with a first inclined surface 306 that is slidably connected to the pressing inclined surface 304.

[0030] When the moving block 202 moves to the left under the action of the reciprocating screw 201, the pressing block 3 at its bottom also moves accordingly. The pressing inclined surface 304 on the left side of the pressing block 3 slides on the first inclined surface 306 on the sliding block 301. Since the pressing block 3 is fixed and the sliding block 301 is movable, the sliding block 301 will move in the direction of compressing the elastic element 302 under the action of the pressing block 3, thereby causing the elastic element 302 to store force. When the pressing block 3 disengages from the surface of the sliding block 301, the elastic potential energy stored in the elastic element 302 will be released, thereby causing the filter plate 4 to vibrate up and down to prevent the filter holes from clogging. The same principle applies when the moving block 202 moves to the right.

[0031] The vibration component in this solution utilizes the power of the drive mechanism to achieve vibration, eliminating the need for an additional power source, thus saving energy and reducing manufacturing costs.

[0032] In addition, elastic elements 302 are provided at the four corners of the bottom of the filter plate 4, which not only make the filter plate 4 vibrate, but also play a buffering role to a certain extent, reducing the impact force of the raw materials on the filter plate 4, protecting the filter plate 4, and extending its service life.

[0033] Furthermore, guide rods 307 are fixedly connected to the top of each support plate 303. The filter plate 4 is slidably connected to the guide rods 307, and each elastic element 302 is sleeved on the outer surface of the guide rod 307. The guide rods 307 provide stable guidance for the up-and-down vibration of the filter plate 4, ensuring that the filter plate 4 remains stable during vibration and does not shift or shake, further improving the vibration effect and filtration stability. At the same time, the guide rods 307 can also prevent the elastic elements 302 from twisting or deforming during compression and extension, ensuring the normal operation of the elastic elements 302, thereby extending the service life of the vibration assembly.

[0034] Secondly, a baffle plate 308 is fixedly connected to the bottom of the filter plate 4 near the support plate 303, and the baffle plate 308 is set at an angle. The baffle plate 308 can prevent the raw material falling from the filter plate 4 from accumulating near the support plate 303, so that the filtered raw material can move smoothly to the discharge port 102, and avoid the raw material from accumulating at the support plate 303 and affecting the filtration effect.

[0035] Working principle:

[0036] When the raw material enters the housing 1 through the feed pipe 101, it passes through the feed pipe 101, the corrugated hose 103, and the distribution pipe 104 in sequence, and finally falls onto the surface of the filter plate 4. At the same time, the operator can start the reciprocating motor 2 to drive the reciprocating screw 201 to rotate. The moving block 202 is threadedly connected to the reciprocating screw 201, so that the moving block 202 can perform reciprocating linear motion on the reciprocating screw 201, thereby driving the distribution pipe 104, which is fixedly connected to the moving block 202, to move back and forth inside the housing 1.

[0037] When the moving block 202 moves to the left under the action of the reciprocating screw 201, the pressing block 3 at its bottom also moves accordingly. The pressing inclined surface 304 on the left side of the pressing block 3 slides on the first inclined surface 306 on the sliding block 301. Since the pressing block 3 is fixed and the sliding block 301 is movable, the sliding block 301 moves downward under the action of the pressing block 3. At the same time, the sliding block 301 moves the filter plate 4 towards the compression elastic element 302 through the support frame 305, thereby causing the elastic element 302 to store force. When the pressing block 3 disengages from the surface of the sliding block 301, the elastic potential energy stored in the elastic element 302 is released, which causes the filter plate 4 to vibrate up and down to prevent the filter holes from clogging. The same principle applies when the moving block 202 moves to the right.
