Description

Technical Field

[0001] The utility model relates to the technical field of corn starch processing, and particularly relates to a device for removing impurities from corn starch. Background Art

[0002] Corn starch is a white powder slightly tinged with light yellow. After soaking corn with 0.3% sulfurous acid, it is made through processes such as crushing, sieving, precipitation, drying, and grinding. After crushing the corn, sieving is a very important step, which can effectively remove impurities and improve the quality of starch. For different removal requirements, the sieving methods are also different.

[0003] However, in actual use, a reciprocating sieve plate is a relatively common sieving device. Since the holes on its surface always pass through the corn starch to be sieved unidirectionally, during the sieving process, it is more likely to cause blockage inside the sieving holes, thereby affecting the sieving effect. Therefore, a device that can efficiently sieve and is convenient for cleaning blockages is needed. At the same time, for different sieving particle size requirements, the device also needs to be convenient for adjustment and replacement to meet different sieving requirements. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for removing impurities from corn starch, which solves the problems that the existing device needs to be convenient for sieving corn starch, cleaning blockages, and needs to be convenient for adjusting the sieving aperture to meet different requirements.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for removing impurities from corn starch, including a protective cover, a rotating plate, and a sieve plate. A rotating plate is arranged inside the protective cover, and a plurality of sieve plates are slidably connected around the outer wall of the rotating plate. One end of the rotating plate is connected with a baffle, a gas guide pipe is arranged on the top of the rotating plate, and cleaning rollers are arranged on both sides of the outer wall of the rotating plate;

[0006] A plurality of connecting strips are fixedly connected around one side of the rotating plate for supporting connection. A connecting ring is arranged at the end of the connecting strip far away from the rotating plate. Both sides of the sieve plate are slidably connected with the connecting strips;

[0007] A groove corresponding to the connecting ring is arranged on one side of the baffle for shielding, and a material guide pipe is arranged at the center of the baffle;

[0008] The gas guide pipe for blowing is located inside the protective cover, and a plurality of nozzles are arranged on the side of the gas guide pipe close to the rotating plate.

[0009] Preferably, one end of the protective cover away from the baffle is fixedly connected with a mounting plate. The bottom of the protective cover is connected with a discharge port. A rotating motor is arranged at the corresponding position of the side of the mounting plate away from the protective cover and the rotating plate. The power output end of the rotating motor penetrates through the mounting plate and the protective cover and is fixedly connected with the rotating plate.

[0010] Preferably, a sliding groove is formed on the outer wall of the connecting strip, and a sliding block corresponding to the sliding groove is arranged on the side wall of the screening plate. The screening plate is slidably connected with the sliding groove through the sliding block. Through holes corresponding to the screening plate are formed at both ends of the protective cover.

[0011] Preferably, driving motors are arranged on both sides of the side wall of the mounting plate close to the rotating motor. The power output ends of the driving motors penetrate through the mounting plate and the inside of the protective cover and are fixedly connected with the cleaning roller. One side of one end of the cleaning roller is eccentrically connected with the power output end of the driving motor. The outer wall of the cleaning roller is attached to the screening plate.

[0012] Preferably, both sides of the connecting strip away from the screening plate incline towards the center, and both sides of the side surface of the screening plate close to the rotating plate are closely attached to the outer wall of the rotating plate.

[0013] Preferably, one end of the air duct penetrates through the inside of the protective cover and the mounting plate and is communicated with an air pump. The end of the material guiding pipe away from the protective cover is communicated with a feeding device.

[0014] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0015] 1. Start the driving motor, so that the cleaning roller is driven to rotate. At the same time, because the cleaning roller is eccentrically connected with the driving motor, the cleaning roller can intermittently fit with the outer wall of the screening plate to realize cleaning. And the gas can be conveyed to the position of the air duct through an external air pump and then sprayed out through the nozzle, so as to realize the impact of the gas on the screening plate and further clean the blocked position. At the same time, because the screening plate is in a rotating state, the separation from the corn starch can be effectively realized, avoiding continuous screening and facilitating the cleaning of the blockage.

[0016] 2. Pull the screening plate along the sliding groove, so that the screening plate slides inside the sliding groove through the sliding block, realizing the separation of the screening plate, which is convenient for cleaning, maintenance or replacement. Then insert the processed screening plate along the sliding groove to the outer wall of the connecting strip to realize replacement. At the same time, press the baffle again to be clamped with the connecting ring to block one end of the screening plate and prevent it from falling off, so as to facilitate the replacement of screening plates with different apertures for use.

[0025] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0026] The present utility model provides a corn starch impurity removal device as shown in Figures 1-5 , which includes a protective cover 1, a rotating plate 2 and a screening plate 3. The inside of the protective cover 1 is provided with a rotating plate 2. The outer wall of the rotating plate 2 is slidably connected with a plurality of screening plates 3 in a surrounding manner. One end of the rotating plate 2 is connected with a baffle 4. The top of the rotating plate 2 is provided with an air duct 5. Both sides of the outer wall of the rotating plate 2 are provided with cleaning rollers 6; A plurality of connecting strips 201 are fixedly connected in a surrounding manner on one side of the rotating plate 2 for supporting connection. One end of the connecting strip 201 away from the rotating plate 2 is provided with a connecting ring 204. Both sides of the screening plate 3 are slidably connected with the connecting strips 201; A groove corresponding to the connecting ring 204 is provided on one side of the baffle 4 for shielding. The center of the inside of the baffle 4 is provided with a guide pipe 401; The air duct 5 for blowing is located inside the protective cover 1, and a plurality of nozzles are provided on the side of the air duct 5 close to the rotating plate 2.

[0027] As Figure 1 , Figure 2 shown, one end of the protective cover 1 away from the baffle 4 is fixedly connected with a mounting plate 102. The bottom of the protective cover 1 is connected with a discharge port 101. A rotating motor 203 is arranged at the corresponding position of the side of the mounting plate 102 away from the protective cover 1 and the rotating plate 2. The power output end of the rotating motor 203 penetrates through the mounting plate 102 and the protective cover 1 and is fixedly connected with the rotating plate 2. Starting the rotating motor 203 causes the rotating motor 203 to drive the rotating plate 2 to rotate, so that the rotating plate 2 drives the connecting bar 201 to rotate, and the screening plate 3 rotates, thereby realizing the rotational screening of corn starch.

[0028] As Figure 4 , Figure 5 shown, a chute 202 is formed on the outer wall of the connecting bar 201, and a slider corresponding to the chute 202 is arranged on the side wall of the screening plate 3. The screening plate 3 is slidably connected with the chute 202 through the slider. Through holes corresponding to the screening plate 3 are formed at both ends of the protective cover 1. Both sides of the connecting bar 201 on the side away from the screening plate 3 incline towards the center. Both sides of the side surface of the screening plate 3 close to the rotating plate 2 are closely attached to the outer wall of the rotating plate 2, which can conveniently pull the screening plate 3 along the chute 202, so that the screening plate 3 slides inside the chute 202 through the slider, realizing the separation of the screening plate 3, facilitating its cleaning, maintenance or replacement, and then inserting the processed screening plate 3 along the chute 202 to the outer wall of the connecting bar 201, thereby realizing the replacement.

[0029] As Figure 2 , Figure 4 shown, driving motors 601 are arranged on both sides of the side wall of the mounting plate 102 close to the rotating motor 203. The power output ends of the driving motors 601 penetrate through the mounting plate 102 and the inside of the protective cover 1 and are fixedly connected with the cleaning roller 6. One side of one end of the cleaning roller 6 is eccentrically connected with the power output end of the driving motor 601. The outer wall of the cleaning roller 6 is attached to the screening plate 3. Starting the driving motor 601 causes the cleaning roller 6 to be driven to rotate. At the same time, because the cleaning roller 6 is eccentrically connected with the driving motor 601, the cleaning roller 6 can intermittently contact the outer wall of the screening plate 3 for cleaning.

[0030] As Figure 1 , Figure 2 shown, one end of the air duct 5 penetrates through the inside of the protective cover 1 and the mounting plate 102 and is communicated with an air pump. One end of the material guide pipe 401 away from the protective cover 1 is communicated with a feeding device. The gas can be transported to the position of the air duct 5 through an external air pump and then sprayed out through a nozzle, realizing the impact of the gas on the screening plate 3 and further cleaning the blocked position.

[0031] When in use, it is convenient to use an external feeding device to transport the crushed corn starch raw material into the inside of the screening plate 3 through the material guiding pipe 401. Then, start the rotating motor 203, so that the rotating motor 203 drives the rotating plate 2 to rotate. Thereby, the rotating plate 2 drives the connecting bar 201 to rotate, making the screening plate 3 rotate, so as to realize the rotating screening of corn starch. At the same time, it is also convenient to start the driving motor 601, and then the cleaning roller 6 is driven to rotate. Since the cleaning roller 6 is eccentrically connected to the driving motor 601, the cleaning roller 6 can be intermittently attached to the outer wall of the screening plate 3 for cleaning. And gas can be transported to the position of the air guide pipe 5 through an external air pump, and then sprayed out through the nozzle, so as to realize the impact of the gas on the screening plate 3 and further clean the blocked position. At the same time, since the rotating plate 2 drives the screening plate 3 to be in a rotating state, it can effectively realize the separation from the corn starch, avoid continuous screening, and facilitate the cleaning of blockages.

[0032] When it is necessary to replace and adjust the screening plate 3, it is convenient to pull the baffle 4, thereby releasing the clamping connection between the side of the baffle 4 and the connecting ring 204, and then releasing the blockage of one end of the screening plate 3. It is convenient to pull the screening plate 3 along the sliding groove 202, so that the screening plate 3 slides mutually with the inside of the sliding groove 202 through the slider, realizing the separation of the screening plate 3, facilitating its cleaning, maintenance or replacement. Then, insert the processed screening plate 3 along the sliding groove 202 to the outer wall of the connecting bar 201 to realize the replacement. At the same time, press the baffle 4 again to be clamped with the connecting ring 204 to block one end of the screening plate 3 and prevent it from falling off. Thus, it is convenient to replace the screening plates 3 with different apertures for use, which can meet different screening requirements.

[0033] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
