Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biomass particle processing, in particular to a biomass particle scrap filtering device. Background Art
[0002] Biomass particles are environmentally friendly new energy particles formed by cold-state densification processing of crushed biomass straw, forestry waste and other raw materials using pressure rollers and ring dies at normal temperature. After the biomass particles are processed and formed, scraps generated by extrusion are mixed inside. This part of the scraps needs to be filtered out before the biomass particles are packaged.
[0003] Published patent: A biomass particle scrap filtering device (Publication No.: CN218282643U), including a housing and a connecting plate. Symmetrically rotatably connected to the side wall of the connecting plate are sieve plates. In the utility model, through the coordinated setting among the vertical rod, the turntable, the round-headed knocking rod and the vibrating plate, the sieve plates vibrate and intermittently rotate upward reciprocally. That is, the sieve plates can continuously shake, preventing the scraps in the material particles from blocking the sieve holes on the sieve plates and improving the filtering effect of the device.
[0004] The above device has the following defects. The above device filters through sieve plates. During the process of vibrating the sieve plates, the biomass particles will also be damaged, resulting in more broken biomass particles. Moreover, during filtration, particles with various degrees of fragmentation are grouped together, which is not conducive to the subsequent utilization of the broken particles. And because the filtering device is too large in size, when loading materials, workers need to climb high to carry the particles, which poses a certain safety hazard. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and propose a biomass particle scrap filtering device.
[0006] To achieve the above object, the utility model adopts the following technical solution: A biomass particle crushing and filtering device, comprising a fixed seat, a feeding cylinder, a first filter pipe and a second filter pipe. The feeding cylinder is located at the upper end of the fixed seat. A protective cover is fixedly connected to the upper end of the fixed seat. A feeding inclined plate is fixedly connected to one side of the upper end of the fixed seat, and both sides of the feeding inclined plate are connected to the protective cover. Legs are fixedly connected to all four sides of the lower end of the fixed seat. A first mounting seat is fixedly connected to the lower end of the fixed seat. A first motor is fixedly connected to the middle of the first mounting seat. A rotating shaft is fixedly connected to the output end of the first motor. One end of the rotating shaft passes through the fixed seat and is rotatably connected inside the feeding cylinder. A spiral blade is fixedly connected to the outer surface of the end of the rotating shaft passing through the fixed seat, and the spiral blade is rotatably connected to the middle of the upper end of the fixed seat and inside the feeding cylinder. A feeding pipe is fixedly connected to one side of the upper end of the feeding cylinder. The lower end of the feeding pipe extends into the upper end inside the first filter pipe. A discharging pipe is fixedly connected to the lower end of the first filter pipe. Air inlet pipes are fixedly connected to one side of the first filter pipe and the second filter pipe respectively. Connecting covers are fixedly connected to the other side of the first filter pipe and the second filter pipe.
[0007] As a further description of the above technical solution:
[0008] The two air inlet pipes are respectively communicated with the first filter pipe and the second filter pipe. Filter plates are fixedly connected to the ends of the two air inlet pipes far away from the first filter pipe and the second filter pipe. The filter plates can block dust and prevent dust from entering the inside of the first filter pipe and the second filter pipe. Air enters the air inlet pipes and flows from the air inlet pipes to the first filter pipe and the second filter pipe, and performs air separation on the biomass particles passing through the first filter pipe, selecting unqualified products. The particles filtered out from the first filter pipe are those with a mass less than four times the original, and the particles filtered in the middle of the second filter pipe are those with a mass less than eight times the original.
[0009] As a further description of the above technical solution:
[0010] A second mounting seat is fixedly connected to the inside of the air inlet pipe. A second motor is fixedly connected to the middle of the second mounting seat, and the output end of the second motor faces the first filter pipe and the second filter pipe. A fan blade is fixedly connected to the output end of the second motor. By driving the fan blade to rotate by the second motor, external air enters the inside of the air inlet pipe, so that a large amount of air accelerates and flows towards the first filter pipe and the second filter pipe.
[0011] As a further description of the above technical solution:
[0012] The two groups of the connecting covers are respectively communicated with the first filter tube and the second filter tube. The lower ends of the two groups of the connecting covers are detachably connected with the material crushing collection buckets. One ends of the two groups of the connecting covers far away from the first filter tube and the second filter tube are fixedly connected with baffles. A plurality of ventilation holes are arranged on the upper part of the baffles, and the air blown into the interior of the connecting covers flows out from the ventilation holes.
[0013] As a further description of the above technical solution:
[0014] Fixing frames are fixedly connected to the outer surfaces of the material conveying cylinder, the first filter tube and the second filter tube. A support frame is arranged at the lower end of the material crushing collection bucket on one side of the first filter tube. One group of the material crushing collection buckets can be supported by the support frame, and the device can be supported by the fixing frames.
[0015] As a further description of the above technical solution:
[0016] The lower end of the feeding pipe is fixedly connected with the second filter tube. The lower end of the second filter tube is fixedly connected with a support seat. An integral material collection bucket is slidably connected to the middle of the support seat. A handle is fixedly connected to one side of the integral material collection bucket. The particles falling in the second filter tube finally fall into the interior of the integral material collection bucket. The integral material collection bucket can be pulled out from the middle of the support seat through the handle, which is convenient for workers to collect the complete particles.
[0017] The utility model has the following beneficial effects:
[0018] 1. In the utility model, firstly, workers pour the particles onto the middle of the fixed seat from the feeding inclined plate. The protective cover can prevent the particles from leaking out of the middle of the fixed seat. The first motor drives the spiral blade to rotate through the rotating shaft. The spiral blade transports the particles from the lower end of the material conveying cylinder to the upper end of the material conveying cylinder and falls into the interior of the first filter tube from the feeding tube. The height of the fixed seat is lower, and workers do not need to climb to a height for feeding, which is safer.
[0019] 2. In the utility model, after the particles enter the middle of the first filter tube, they fall downward due to gravity. The rotation speed of the second motor on one side of the first filter tube is less than the rotation speed of the second motor on one side of the second filter tube, so that the wind force in the middle of the first filter tube is smaller. The particles filtered out from the first filter tube are those with a mass less than four times the original. The particles filtered in the middle of the second filter tube are those with a mass less than eight times the original. The particles with a mass greater than eight times the original after crushing will fall into the interior of the integral material collection bucket, thereby classifying the particles into three different specifications and improving the utilization rate of the particles.

[0029] Refer to Figures 1-5, an embodiment provided by the present utility model: a biomass particle crushing and filtering device, comprising a fixed seat 1, a feeding cylinder 2, a first filter tube 4 and a second filter tube 5. The feeding cylinder 2 is located at the upper end of the fixed seat 1. A protective cover is fixedly connected to the upper end of the fixed seat 1. An upper feeding inclined plate 6 is fixedly connected to one side of the upper end of the fixed seat 1, and both sides of the upper feeding inclined plate 6 are connected to the protective cover.

A first motor 8 is fixedly connected to the middle of the first mounting seat 7. An output end of the first motor 8 is fixedly connected to a rotating shaft 9. One end of the rotating shaft 9 passes through the fixed seat 1 and is rotatably connected inside the feeding cylinder 2. A spiral blade 10 is fixedly connected to the outer surface of the end of the rotating shaft 9 passing through the fixed seat 1, and the spiral blade 10 is rotatably connected to the middle of the upper end of the fixed seat 1 and inside the feeding cylinder 2. A feeding tube 3 is fixedly connected to one side of the upper end of the feeding cylinder 2. The lower end of the feeding tube 3 extends into the upper end inside the first filter tube 4. A discharge tube 11 is fixedly connected to the lower end of the first filter tube 4. Air inlet tubes 12 are fixedly connected to one side of both the first filter tube 4 and the second filter tube 5. A connecting cover 17 is fixedly connected to the other side of both the first filter tube 4 and the second filter tube 5.
[0030] Two groups of air inlet tubes 12 are respectively communicated with the first filter tube 4 and the second filter tube 5. Filter plates 13 are fixedly connected to the ends of the two groups of air inlet tubes 12 far away from the first filter tube 4 and the second filter tube 5. The filter plates 13 can block dust and prevent dust from entering the inside of the first filter tube 4 and the second filter tube 5. Air enters the air inlet tubes 12 and flows from the air inlet tubes 12 to the first filter tube 4 and the second filter tube 5, and performs air separation on the biomass particles passing through the first filter tube 4 to select unqualified products. The particles filtered out from the first filter tube 4 are those with a mass less than four times the original. The particles filtered in the middle of the second filter tube 5 are those with a mass less than eight times the original. A second mounting seat 14 is fixedly connected to the inside of the air inlet tube 12. A second motor 15 is fixedly connected to the middle of the second mounting seat 14, and the output end of the second motor 15 faces the first filter tube 4 and the second filter tube 5. A fan blade 16 is fixedly connected to the output end of the second motor 15. By driving the fan blade 16 to rotate through the second motor 15, external air enters the inside of the air inlet tube 12, so that a large amount of air accelerates and flows towards the first filter tube 4 and the second filter tube 5;
[0031] Two groups of connecting covers 17 are respectively communicated with the first filter pipe 4 and the second filter pipe 5. The lower ends of the two groups of connecting covers 17 are detachably connected with the shredded material collecting buckets 19. One end of the two groups of connecting covers 17 far away from the first filter pipe 4 and the second filter pipe 5 is fixedly connected with a baffle 18. A plurality of ventilation holes are arranged in the upper part of the baffle 18. The air blown into the inside of the connecting cover 17 flows out from the ventilation holes. Fixed frames are fixedly connected to the outer surfaces of the feeding cylinder 2, the first filter pipe 4 and the second filter pipe 5. A support frame is arranged at the lower end of the shredded material collecting bucket 19 on one side of the first filter pipe 4. One group of shredded material collecting buckets 19 can be supported through the support frame. The device can be supported through the fixed frame. The lower end of the feeding pipe 11 is fixedly connected with the second filter pipe 5. The lower end of the second filter pipe 5 is fixedly connected with a support seat 20. A whole material collecting bucket 21 is slidably connected to the middle of the support seat 20. A handle is fixedly connected to one side of the whole material collecting bucket 21. The particles falling from the second filter pipe 5 finally fall into the inside of the whole material collecting bucket 21. The whole material collecting bucket 21 can be pulled out from the middle of the support seat 20 through the handle, which is convenient for workers to collect the complete particles.
[0032] Working principle: When in use, particles are injected into the middle of the fixed seat 1 through the feeding inclined plate 6. The protective cover can prevent the particles from leaking out of the middle of the fixed seat 1, so that the amount of particles poured into the middle of the fixed seat 1 can be increased, making the height of the particles poured into the middle of the fixed seat 1 exceed the lower end of the material conveying cylinder 2. The first motor 8 drives the spiral blade 10 to rotate through the rotating shaft 9. When the spiral blade 10 rotates, the particles located in the middle of the fixed seat 1 are transported to the middle of the material conveying cylinder 2 by the spiral blade 10. Then, the spiral blade 10 continuously transports the particles to the upper end of the material conveying cylinder 2. After the particles reach the upper end of the material conveying cylinder 2, they will fall into the inner part of the blanking cylinder 3. The particles fall along the blanking cylinder 3 into the inner part of the first filter tube 4. The second motor 15 drives the fan blade 16 to rotate, causing a large amount of air to enter the inner parts of the first filter tube 4 and the second filter tube 5 from the air inlet pipe 12 and flow towards the connecting cover 17, and finally flow to the outside through the ventilation holes. When the particles move downward along the first filter tube 4 and the second filter tube 5, the high-speed flow of air will carry away the broken particles with small mass. The carried broken particles enter the connecting cover 17 and are dropped by the baffle 18 and then fall into the inner part of the broken material collection bucket 19. The particles that fall below the first filter tube 4 will fall along the blanking pipe 11 into the inner part of the second filter tube 5. After these particles are filtered once, some particles fall into the inner part of the broken material collection bucket 19, and some particles continue to move downward along the second filter tube 5 and fall into the inner part of the whole material collection bucket 21. The rotation speed of the second motor 15 on one side of the first filter tube 4 is less than the rotation speed of the second motor 15 on one side of the second filter tube 5, making the wind force in the middle of the first filter tube 4 smaller. The particles filtered out from the first filter tube 4 are those with a mass less than one-fourth of the original, and the particles filtered in the middle of the second filter tube 5 are those with a mass less than one-eighth of the original. The particles with a breakage less than 20% will fall into the inner part of the whole material collection bucket 21, thus classifying the particles into three different specifications, improving the utilization rate of the particles. Then, the broken material collection bucket 19 can be taken out, and the whole material collection bucket 21 can be taken out by the handle, so that three different specifications of particles can be taken out.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
