DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0026] like Figure 1-7 As shown, the utility model provides a raw material impurity removal device for biomass fuel production, including an impurity removal box 1, a closing plate 2 is fixedly installed on the top of the impurity removal box 1, and a partition plate 6 is fixedly installed inside, a chip storage plate 7 is arranged at one end of the partition plate 6, a plurality of feed ports 3 are fixedly installed on the top of the closing plate 2, a screening component 4 and an impurity removal mechanism 5 are arranged inside the impurity removal box 1, the screening component 4 includes a screening plate 401, a guide block 402 and a limit block 403, the screening plate 401 is limited by the guide block 402 and the limit block 403, the impurity removal mechanism 5 includes a motor 501, a cam 502, a first push plate 503 and a second push plate 504, the motor 501 can drive the screening plate 401 to move reciprocatingly vertically through the motor 501, and drive the second push plate 504 and the first push plate 503 to push the impurities on the top of the chip storage plate 7, and the screening plate 401 can vibrate the raw materials and impurities when moving back and forth.

[0027] When it is necessary to remove impurities from the raw materials, the staff inserts the chip storage plate 7 into the partition plate 6 so that the impurity removal box 1 and the partition plate 6 limit the chip storage plate 7, and then starts the motor 501. After the motor 501 is started, the raw materials are poured into the screening plate 401 through the feed port 3. Since the screening plate 401 is inclined, the raw materials and impurities can move along the inclined direction of the screening plate 401 at this time, and the impurities pass through the screening plate 401 and fall onto the chip storage plate 7 for storage during the movement. The output end of the motor 501 rotates When the cam 502 is in motion, the cam 502 can rotate, and when the cam 502 rotates, the bottom of the screen plate 401 can be intermittently squeezed. Since the screen plate 401 is limited by the guide block 402, the screen plate 401 can move vertically at this time. When the cam 502 is separated from the bottom of the screen plate 401, the screen plate 401 moves vertically quickly under the action of its own gravity, and the moving distance is limited by the limit block 403. After the rapid movement, the screen plate 401 can vibrate the raw materials and impurities on its top, thereby improving the separation effect and impurity removal effect of the impurities;

[0028] When the output end of the motor 501 rotates, it can also drive the first push plate 503 and the second push plate 504 to reciprocate horizontally. The first push plate 503 pushes impurities to prevent impurities from piling up too high and affecting subsequent impurity filtering, thereby improving impurity removal efficiency and applicability.

[0029] In one embodiment, the screening assembly 4 also includes a limiting groove 404, which is fixedly connected to the interior of the impurity removal box 1, the guide block 402 is fixedly connected to the top of the screening plate 401 and slidably cooperates with the limiting groove 404, the limiting block 403 is fixedly sleeved on the guide block 402 and fits with the top of the limiting groove 404, the screening plate 401 fits with the inner wall of the impurity removal box 1, and one end fits with the partition plate 6.

[0030] When the screening plate 401 is squeezed by the cam 502, it moves vertically under the action of the guide block 402. When the guide block 402 moves, it slides with the limit groove 404 and drives the limit block 403 to move. When the screening plate 401 is no longer subjected to force, the guide block 402 and the limit block 403 move vertically downward, and after the movement, the screening plate 401 can vibrate the raw materials on its surface. At the same time, the limit block 403 can be against the top of the limit groove 404 to limit the moving distance of the screening plate 401, making the structure more reasonable.

[0031] In one embodiment, the impurity removal mechanism 5 also includes a rotating shaft 505. When the output end of the motor 501 rotates, it can drive the rotating shaft 505 to rotate. After the rotating shaft 505 rotates, it drives the cam 502 to rotate. When the cam 502 rotates, it can intermittently squeeze the screen plate 401 and drive the screen plate 401 to move vertically.

[0032] When the output end of the motor 501 rotates, it first drives the rotating shaft 505 to rotate, and when the rotating shaft 505 rotates, it drives the cam 502 to rotate, so that the cam 502 can intermittently vibrate the screening plate 401 in a continuous rotating state, thereby improving applicability.

[0033] In one embodiment, the impurity removal mechanism 5 also includes a first reciprocating screw rod 506 and a second reciprocating screw rod 507. When the output end of the motor 501 rotates, it can drive the first reciprocating screw rod 506 and the second reciprocating screw rod 507 to rotate. When the first reciprocating screw rod 506 rotates, it can drive the first push plate 503 to reciprocate horizontally. When the second reciprocating screw rod 507 rotates, it can drive the second push plate 504 to reciprocate horizontally.

[0034] After the rotating shaft 505 rotates, it can drive the first reciprocating screw rod 506 and the second reciprocating screw rod 507 to rotate. After the first reciprocating screw rod 506 and the second reciprocating screw rod 507 rotate, they drive the first push plate 503 and the second push plate 504 to move back and forth horizontally, thereby pushing impurities, and will not cause impurities to accumulate and affect the subsequent impurity collection effect.

[0035] In one embodiment, the impurity removal mechanism 5 also includes a driving gear 508 and a driven gear 509. The rotating shaft 505 and the first reciprocating screw rod 506 both pass through the impurity removal box 1. The two ends of the rotating shaft 505 are fixedly connected to the cam 502 and the output end of the motor 501 respectively. The driving gear 508 is fixedly sleeved on the rotating shaft 505. The driven gear 509 is fixedly sleeved on the first reciprocating screw rod 506 and meshes with the driving gear 508. One end of the second reciprocating screw rod 507 is fixedly connected to the first reciprocating screw rod 506, and the other end rotates with the partition plate 6. The first push plate 503 is sleeved on the first reciprocating screw rod 506. The two ends of the first push plate 503 are in contact with the inner wall of the impurity removal box 1 and are threadedly connected to the first reciprocating screw rod 506. The two ends of the second push plate 504 are in contact with the inner wall of the motor 501 and are threadedly connected to the second reciprocating screw rod 507.

[0036] When the rotating shaft 505 rotates, it can drive the driving gear 508 to rotate. When the driving gear 508 rotates, it meshes with the driven gear 509 to drive the driven gear 509 to rotate. When the driven gear 509 rotates, it drives the first reciprocating screw rod 506 to rotate. After the first reciprocating screw rod 506 rotates, it drives the second reciprocating screw rod 507 to rotate. Since the first push plate 503 and the second push plate 504 are both limited by the inner wall of the impurity removal box 1, at this time, under the rotation of the first reciprocating screw rod 506 and the second reciprocating screw rod 507, the first push plate 503 and the second push plate 504 can reciprocate horizontally and push impurities to avoid excessive accumulation of impurities and affect the subsequent filtering of impurities, thereby improving the impurity removal efficiency and applicability.

[0037] In one embodiment, the impurity removal mechanism 5 further includes a fixing member 510 , a frame 10 is fixedly mounted on the outer wall of the impurity removal box 1 , the fixing member 510 is fixedly connected to the impurity removal box 1 , and the mounting end of the motor 501 is fixedly mounted to the fixing member 510 .

[0038] The fixing member 510 is used to fix the motor 501 and prevents the motor 501 from being easily detached, thereby improving the fixing effect.

[0039] In one embodiment, a discharge port 601 is opened at one end of the partition plate 6, and the partition plate 6 divides the inner wall of the impurity removal box 1 into an impurity removal chamber 101 and a storage chamber 102. A plurality of box doors 8 are arranged on one side of the impurity removal box 1, and a pull plate 701 is fixedly installed at one end of the chip storage plate 7, and is slidably matched with the partition plate 6.

[0040] The discharge port 601 is used to discharge the raw materials. The filtered raw materials can fall into the storage chamber 102 through the discharge port 601 and be stored. When the raw materials need to be taken out, the staff can take out the raw materials by opening the box door 8. If the impurities need to be cleaned, the collecting device is first placed at the bottom of the impurity removal chamber 101, and then the chip storage plate 7 is pulled by the pulling plate 701. Since the chip storage plate 7 is in contact with the impurity removal box 1, the impurities on the top of the chip storage plate 7 can be scraped out by the impurity removal box 1 and fall into the collecting device.

[0041] The following is a detailed description of the working principle of the raw material impurity removal device for biomass fuel production:

[0042] When it is necessary to remove impurities from the raw materials, the staff first pushes the chip storage plate 7 through the pull plate 701, so that the chip storage plate 7 is inserted into the partition plate 6, so that the impurity removal box 1 and the partition plate 6 limit the chip storage plate 7, and then starts the motor 501. After the motor 501 is started, the raw materials are poured into the screening plate 401 through the feed port 3. Since the screening plate 401 is inclined, the raw materials and impurities can move along the inclined direction of the screening plate 401 at this time, and when moving, the impurities pass through the screening plate 401 and fall onto the chip storage plate 7 for storage. When the output end of the motor 501 rotates, it can drive the rotation The shaft 505 rotates, and the rotation shaft 505 can drive the cam 502 to rotate. When the cam 502 rotates, it can intermittently squeeze the bottom of the screen plate 401. Since the screen plate 401 is limited by the guide block 402 and the limit groove 404, the screen plate 401 can move vertically at this time. When the cam 502 is separated from the bottom of the screen plate 401, the screen plate 401 moves vertically quickly under the action of its own gravity, and the moving distance is limited by the limit block 403. After the rapid movement, the screen plate 401 can vibrate the raw materials and impurities on its top, thereby improving the separation effect and impurity removal effect of the impurities;

[0043] When the rotating shaft 505 rotates, it can drive the driving gear 508 to rotate. When the driving gear 508 rotates, it meshes with the driven gear 509 to drive the driven gear 509 to rotate. When the driven gear 509 rotates, it drives the first reciprocating screw rod 506 to rotate. After the first reciprocating screw rod 506 rotates, it drives the second reciprocating screw rod 507 to rotate. Since the first push plate 503 and the second push plate 504 are both limited by the inner wall of the impurity removal box 1, at this time, under the rotation of the first reciprocating screw rod 506 and the second reciprocating screw rod 507, the first push plate 503 and the second push plate 504 can reciprocate horizontally and push impurities to avoid excessive accumulation of impurities and affect the subsequent impurity filtering, thereby improving the impurity removal efficiency and applicability;

[0044] The filtered raw materials can fall into the storage chamber 102 through the discharge port 601 and be stored. When the raw materials need to be taken out, the staff can take out the raw materials by opening the box door 8. If the impurities need to be cleaned, the collecting device is first placed at the bottom of the impurity removal chamber 101, and then the chip storage plate 7 is pulled by the pulling plate 701. Since the chip storage plate 7 is in contact with the impurity removal box 1, the impurities on the top of the chip storage plate 7 can be scraped out by the impurity removal box 1 and fall into the collecting device.

[0045] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
