Description

Technical Field

[0001] This utility model belongs to the field of xylose production technology, and specifically relates to a corn cob impurity removal device. Background Technology

[0002] In my country, corn cobs are the main raw material for xylose production. Polysaccharides in corn cobs are degraded into monosaccharides through acid hydrolysis, and then purified to produce high-purity xylose. However, during the xylose production process using corn cobs, impurities such as soil and stones are inevitably present during collection. Corn leaves also have a low hemicellulose content, making them unsuitable for xylose production. Furthermore, soil can affect activated carbon consumption. Therefore, when producing xylose from corn cobs, it is necessary to use a purification device to remove impurities such as soil and stones.

[0003] Existing corn cob impurity removal devices generally use vibration or shaking to shake off impurities such as mud and stones adhering to the surface of the corn cob. However, since no force can be directly applied to the corn cob, the vibration force on the corn cob in the inner area is relatively small. As a result, the impurities adhering to the corn cob in the inner area cannot be removed quickly and directly. Effective impurity removal can only be carried out after the corn cob in the inner area is stirred to the outer area, which will have an adverse effect on the overall impurity removal efficiency of the corn cob. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a corn cob impurity removal device, which not only meets the basic requirements for corn cob impurity removal, but also can directly and effectively remove impurities from corn cobs in different areas of the device, thereby improving the overall efficiency of corn cob impurity removal.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a corn cob impurity removal device, including a base, a plurality of springs vertically arranged on the top of the base, a top opening and a cone-shaped impurity removal box at the bottom of the plurality of springs, a discharge port at the bottom of the impurity removal box, a vibrating motor at the bottom of the impurity removal box, connecting shafts horizontally penetrating and rotatably arranged on the left and right sides of the impurity removal box, a drive module for rotating the connecting shafts at the side of the impurity removal box, an impurity removal screen cylinder arranged between the two connecting shafts, a plurality of impurity removal balls arranged in the impurity removal screen cylinder, an inlet and outlet groove arranged on the top of the impurity removal screen cylinder, a grid plate arranged on the inner wall of the inlet and outlet groove, the grid holes on the grid plate can block the impurity removal balls and allow impurities and corn cobs to pass through, and a baffle screen plate that can block corn cobs and allow impurities to pass through can also be detachably arranged on the inlet and outlet groove.

[0006] As a further improvement of this utility model, the drive module includes a drive motor horizontally disposed on the outer wall of the left end of the impurity removal box. A drive gear is disposed on the output shaft of the drive motor, and a driven gear meshing with the drive gear is disposed on the connecting shaft on the left side. Through the meshing transmission of the drive motor, the drive gear, and the driven gear, the rotation drive of the connecting shaft is realized; thereby, the rotation drive of the impurity removal screen cylinder is realized.

[0007] As a further improvement of this utility model, a feed hopper is also provided at the top of the inlet and outlet trough. Through the feed hopper, users can more conveniently add corn cobs into the impurity removal screen cylinder, effectively preventing corn from falling to the outside of the impurity removal screen cylinder.

[0008] As a further improvement of this utility model, an extension ring plate is provided on the inner side wall of the inlet and outlet groove, and the fence plate is snapped and fixed to the extension ring plate. The extension ring plate is provided with a snap-fit ​​groove that matches the fence plate. The side end of the fence plate is provided with a first hand-tightening bolt for screwing and fixing the extension ring plate. The extension ring plate is provided with a first threaded connection hole that matches the first hand-tightening bolt.

[0009] As a further improvement of this utility model, the baffle screen plate is snapped into the inlet and outlet groove and abuts against the top of the extension ring plate. The baffle screen plate is provided with a second hand-tightening bolt for screwing and fixing the extension ring plate, and the extension ring plate is provided with a second threaded connection hole that matches the second hand-tightening bolt.

[0010] As a further improvement of this utility model, a first handle is provided on the fence plate and a second handle is provided on the material blocking screen plate.

[0011] As a further improvement of this invention, a transparent observation window is also provided on the impurity removal box. The transparent observation window allows for convenient viewing of the interior of the impurity removal box.

[0012] As a further improvement of this utility model, a guide tube is also provided on the top of the base, and a guide rod that is plugged into and connected to the guide tube is also provided on the bottom of the impurity removal box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Firstly, the vibration generated by the vibrating motor and the elastic support of the springs enable the material in the impurity removal box to be separated from impurities more effectively during the vibration process; the impurity removal balls in the impurity removal screen cylinder collide with corn cobs and impurities during rotation, further improving the impurity removal efficiency.

[0015] Secondly, the design of the first and second hand-tightening bolts makes the installation and disassembly of the fence and the material screen plate more convenient, without the need for special tools.

Detailed Implementation

[0024] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0025] like Figure 1 , 2As shown in Figures 3 and 4, a corn cob impurity removal device includes a base 101. Multiple springs 102 are vertically arranged on the top of the base 101. A removal box 103 with a top opening and a conical bottom is located at the top of all the springs 102. A discharge port 104 is located at the bottom of the removal box 103. A vibration motor 105 is also located at the bottom of the removal box 103. Connecting shafts 106 are horizontally and rotatably arranged through the left and right sides of the removal box 103. The sides of the removal box 103 are also provided with a mechanism for adjusting the connecting shafts 106. The drive module is driven by rotation. A cleaning screen cylinder 107 is provided between two connecting shafts 106. Multiple cleaning balls 108 are provided in the cleaning screen cylinder 107. An inlet / outlet groove 109 is provided at the top of the cleaning screen cylinder 107. A grid plate 110 is provided on the inner wall of the inlet / outlet groove 109. The grid holes on the grid plate 110 can block the cleaning balls 108 and allow impurities and corn cobs to pass through. A baffle screen plate 111 that can block corn cobs and allow impurities to pass through can also be detachably provided on the inlet / outlet groove 109.

[0026] like Figure 1 As shown, the drive module includes a drive motor 201 horizontally mounted on the outer wall of the left end of the impurity removal box 103. A drive gear 202 is mounted on the output shaft of the drive motor 201, and a driven gear 203 meshing with the drive gear 202 is mounted on the connecting shaft 106 on the left side. Through the meshing transmission of the drive motor 201, the drive gear 202, and the driven gear 203, the rotation of the connecting shaft 106 is achieved; consequently, the rotation of the impurity removal screen cylinder 107 is achieved.

[0027] like Figure 2 , 3 As shown in Figure 4, an extension ring plate 301 is provided on the inner side wall of the inlet / outlet groove 109. The fence plate 110 is snapped and fixed to the extension ring plate 301. The extension ring plate 301 is provided with a snap-fit ​​groove 302 that matches the fence plate 110. The side end of the fence plate 110 is provided with a first hand-tightening bolt 303 for screwing and fixing the extension ring plate 301. The extension ring plate 301 is provided with a first threaded connection hole that matches the first hand-tightening bolt 303.

[0028] like Figure 2 , 3 As shown in Figure 4, the baffle screen 111 is snapped into the inlet / outlet slot 109 and abuts against the top of the extension ring plate 301. The baffle screen 111 is provided with a second hand-tightening bolt 304 for screwing and fixing the extension ring plate 301, and the extension ring plate 301 is provided with a second threaded connection hole adapted to the second hand-tightening bolt 304. A first handle is provided on the fence plate 110, and a second handle is provided on the baffle screen 111. A transparent observation window is also provided on the impurity removal box 103. The internal condition of the impurity removal box 103 can be easily viewed through the transparent observation window.

[0029] like Figure 1 As shown, a guide tube 112 is provided on the top of the base 101, and a guide rod 113 that is plugged into and connected to the guide tube 112 is provided on the bottom of the impurity removal box 103.

[0030] like Figure 1 As shown, a feed hopper 305 is also provided on the top of the inlet / outlet trough 109. Through the feed hopper 305, users can more conveniently add corn cobs into the impurity removal screen cylinder 107, effectively preventing corn from falling to the outside of the impurity removal screen cylinder 107, enabling users to feed more quickly and accurately, thereby improving the overall efficiency of impurity removal of corn cobs by improving feeding efficiency.

[0031] The worker can first separate the second hand-tightening bolt 304 from the second threaded connection hole to release the fixation of the connection between the baffle screen plate 111 and the extension ring plate 301. Then, the worker can remove the baffle screen plate 111 from the extension ring plate 301 using the second handle. After that, the worker can separate the first hand-tightening bolt 303 from the first threaded connection hole to release the fixation of the connection between the extension ring plate 301 and the fence plate 110, thereby opening the inlet / outlet trough 109. Then, the corn cob can enter the impurity removal screen cylinder 107 through the feed hopper 305 at the top of the inlet / outlet trough 109. The design of the feed hopper 305 ensures that the material can enter the impurity removal screen cylinder 107 evenly and continuously. Then, the fence plate 110 can be snapped into the snap-fit ​​groove 302 and fixed. Then, the second hand-tightened bolt 304 passes through the side wall of the fence plate 110 and is screwed into the second threaded connection hole, thereby fixing the fence plate 110 onto the extension ring plate 301. The material blocking screen plate 111 abuts against the extension ring plate 301, and the second hand-tightened bolt 304 passes through the side wall of the material blocking screen plate 111 and is screwed into the second threaded connection hole, thereby achieving flexible fixing of the material blocking screen plate 111 and the extension ring plate 301.

[0032] Then, vibration is started. With the cooperation of multiple springs 102 and the vertical guiding action of guide tube 112 and guide rod 113, the impurity removal box 103 and the impurity removal screen 107 vibrate vertically. The vibration causes the corn cobs and impurities in the impurity removal screen 107 to tumble and collide continuously, which helps to separate the impurities from the corn cobs. The impurities leave the impurity removal box 103 quickly and efficiently through the vibration operation. The corn cobs will be trapped in the impurity removal screen 107 because they cannot pass through the screen holes of the impurity removal screen 107 and the baffle screen 111.

[0033] Simultaneously, the worker starts the drive motor 201, which drives the connecting shaft 106 to rotate through the meshing transmission of the driving gear 202 and the driven gear 203, thereby driving the impurity removal screen cylinder 107 to rotate. The impurity removal screen cylinder 107 is equipped with multiple impurity removal balls 108. These impurity removal balls 108 collide with corn cobs and impurities during rotation, further improving the impurity removal effect.

[0034] After the corn cob impurity removal process is completed, the drive motor 201 can be stopped and the inlet / outlet trough 109 can be positioned on the upper side. Then, the baffle screen trough can be removed, and the impurity removal screen cylinder 107 can be rotated, with the inlet / outlet trough 109 positioned on the lower side. Under the vibration drive of the vibration motor 105, the impurity removal box 103 and the impurity removal screen cylinder 107 can be driven to vibrate, so that the corn cob after impurity removal can smoothly leave the impurity removal screen cylinder 107 and then leave the impurity removal box 103.

[0035] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
