Description

Technical Field

[0001] This utility model belongs to the field of negative pressure suction dust removal technology, specifically relating to a negative pressure suction dust removal device for rice polishing. Background Technology

[0002] The rice polishing process generates a large amount of impurities such as rice bran, debris, and dust. If these impurities are not removed in time, they will not only affect the purity and appearance of the finished rice, but may also block the ventilation channels of the polishing equipment and accelerate equipment wear.

[0003] Existing negative pressure suction dust removal devices mostly use a fixed filter structure for impurity filtration. After a period of use, impurities such as rice bran easily adhere to the filter surface and clog the mesh. This leads to a significant decrease in the negative pressure suction of the device, greatly reducing its dust removal efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure suction dust removal device for rice polishing. The movement of the filter cylinder can effectively remove impurities from the surface of the filter cylinder, reducing the clogging effect of impurities adsorbed on the surface of the filter cylinder and causing blockage of the filter cylinder mesh, thereby reducing the phenomenon of reduced negative pressure suction inside the rice polishing equipment when the filter cylinder is blocked.

[0005] The specific technical solution adopted by this utility model is as follows: A negative pressure suction dust removal device for rice polishing includes a box body, an air vent on the upper side of the box body, a fan fixedly connected to the upper end of the box body and communicating with the air vent, a connecting pipe connected to the upper end of the box body away from the fan, a dust suction plate connected to the connecting pipe, and a dust suction opening provided on the lower side of the dust suction plate. The housing contains a movable filter cylinder, the upper end of which is connected to an air vent via a flexible connecting pipe.

[0006] Furthermore, an annular bracket is fixedly connected inside the housing, and a circular tube is vertically slidably connected inside the annular bracket. The upper end of the filter cylinder is fixedly connected to the lower end of the circular tube, and the lower end of the flexible connecting tube is fixedly connected to the upper end of the circular tube. A drive lifting component that is driven and connected to the filter cylinder is fixedly connected inside the housing.

[0007] Furthermore, the driving lifting component includes a support plate fixedly connected to the inside of the housing, a servo motor fixedly connected to the support plate, a transmission shaft rotatably connected to the support plate, and the transmission shaft and the output end of the servo motor being connected in a transmission connection. A transmission sleeve is rotatably connected to the outer side of the transmission shaft. The upper end of the transmission sleeve is fixedly connected to the filter screen cylinder. A transmission round rod is fixedly connected to the outer side of the transmission shaft. A lifting motion guide groove is provided on the inner wall of the transmission sleeve. The transmission round rod and the lifting motion guide groove are slidably connected.

[0008] Furthermore, the lifting motion guide groove includes a guide inclined groove, a wide groove, and a transverse groove formed on the inner wall of the transmission sleeve. The upper end of the guide inclined groove is connected to the upper end of the wide groove, the lower end of the wide groove is connected to one end of the transverse groove, and the other end of the transverse groove is connected to the lower end of the guide inclined groove.

[0009] Furthermore, a spring is fixedly connected between the support plate and the filter cylinder.

[0010] Furthermore, the housing is equipped with an atomizing spray system.

[0011] Furthermore, a drawer-type bottom box is slidably connected to the bottom of the box body, and a water outlet pipe is fixedly connected to the lower end of the outer side of the drawer-type bottom box. A valve is installed on the water outlet pipe, and a filter plate is fixedly connected to the inside of the drawer-type bottom box.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-4 As shown, a negative pressure suction dust removal device for rice polishing includes a box 1, an air vent on the upper side of the box 1, a fan 4 connected to the air vent and fixedly connected to the upper end of the box 1, a connecting pipe 2 connected to the upper end of the box 1 away from the fan 4, a dust suction plate 3 connected to the connecting pipe 2, a dust suction opening provided on the lower side of the dust suction plate 3, and the dust suction plate 3 can be fixedly connected inside the rice polishing equipment. During the polishing process inside the rice polishing equipment, the fan 4 is activated to create negative pressure inside the box 1. Then, the dust suction plate 3 sucks up impurities such as rice bran, debris, and dust inside the rice polishing equipment, thus completing the dust removal work. The housing 1 is equipped with a movable filter cylinder 11. The upper end of the filter cylinder 11 is connected to the air outlet through a flexible connecting pipe 21. When air is discharged through the air outlet, impurities in the air can be filtered through the filter cylinder 11. The movement of the filter cylinder 11 can effectively remove impurities from the surface of the filter cylinder 11, reducing the clogging effect caused by impurities adsorbed on the surface of the filter cylinder 11.

[0017] The flexible connecting pipe 21 can be a telescopic pipe or a rubber hose, or other pipes that can deform.

[0018] The filter cylinder 11 can rotate, move up and down, or vibrate, as specifically as follows: Figures 2-3 As shown, an annular bracket 9 is fixedly connected inside the housing 1. A circular tube 10 is vertically slidably connected inside the annular bracket 9. The annular bracket 9 and the circular tube 10 are limited by anti-rotation groove and anti-rotation block. The upper end of the filter cylinder 11 is fixedly connected to the lower end of the circular tube 10. The lower end of the flexible connecting tube 21 is fixedly connected to the upper end of the circular tube 10. By repeatedly moving the filter cylinder 11 up and down, the impurities on the surface of the filter cylinder 11 can be dislodged.

[0019] like Figures 2-3 As shown, the housing 1 has a fixed internal connection to a drive lifting component that is connected to the filter cylinder 11. The drive lifting component can be an electric telescopic rod or a combination of a motor and a screw, or as shown in the image. Figures 2-4As shown, the driving lifting component includes a support plate 12 fixedly connected inside the housing 1. A servo motor 13 is fixedly connected to the support plate 12, and a transmission shaft 15 is rotatably connected to the support plate 12. The transmission shaft 15 and the output end of the servo motor 13 are connected in a transmission connection. By starting the servo motor 13, the transmission shaft 15 can be driven to rotate. The servo motor 13 should be a waterproof and dustproof motor or have a waterproof and dustproof structure on the outside of the servo motor 13. Alternatively, the servo motor 13 can be located on the outside of the housing 1, as long as it can be connected in a transmission connection with the transmission shaft 15.

[0020] A transmission sleeve 16 is rotatably connected to the outer side of the transmission shaft 15. The upper end of the transmission sleeve 16 is fixedly connected to the filter cylinder 11. A transmission round rod 17 is fixedly connected to the outer side of the transmission shaft 15. A lifting motion guide groove is provided on the inner wall of the transmission sleeve 16. The transmission round rod 17 and the lifting motion guide groove are slidably connected. When the transmission shaft 15 rotates, it can drive the transmission round rod 17 to move inside the lifting motion guide groove, pushing the inner wall of the lifting motion guide groove, so that the transmission sleeve 16 drives the filter cylinder 11 to move up and down.

[0021] Specifically, the lifting motion guide groove includes a guide inclined groove 18, a wide groove 19, and a transverse groove 20 formed on the inner wall of the transmission sleeve 16. The upper end of the guide inclined groove 18 is connected to the upper end of the wide groove 19, the lower end of the wide groove 19 is connected to one end of the transverse groove 20, and the other end of the transverse groove 20 is connected to the lower end of the guide inclined groove 18. The servo motor 13 drives the transmission shaft 15 to rotate counterclockwise. When the transmission shaft 15 rotates into the guide inclined groove 18, it can apply an upward thrust to the inner wall of the guide inclined groove 18, causing the transmission sleeve 16 to move upward. Then, the transmission rod 17 enters the wide groove 19 through the transverse groove 20. At this time, the transmission rod 17 no longer limits the transmission sleeve 16. Under the action of gravity, the transmission sleeve 16 and the filter cylinder 11 can fall. After the transmission sleeve 16 has fallen, the transmission rod 17 can rotate into the guide inclined groove 18. This process can be repeated.

[0022] Meanwhile, a spring 14 can be fixedly connected between the support plate 12 and the filter cylinder 11. When the filter cylinder 11 moves upward, the spring 14 can be stretched. When the transmission rod 17 enters the wide groove 19 through the transverse groove 20, the filter cylinder 11 can be pulled down quickly by the tension of the spring 14.

[0023] like Figures 1-2 As shown, a misting spray 5 can also be installed on the housing 1. The misting spray 5 can spray water mist into the interior of the housing 1 to humidify the debris inside the housing 1 and reduce the phenomenon that the debris inside the housing 1 flows with the gas to the filter screen 11.

[0024] like Figures 1-2As shown, a drawer-type bottom box 6 is slidably connected to the bottom of the box 1. The debris entering the box 1 can fall into the drawer-type bottom box 6, so that the debris can be collected by the drawer-type bottom box 6. By sliding the drawer-type bottom box 6 out, the debris inside the drawer-type bottom box 6 can be discharged relatively easily.

[0025] A water outlet pipe 7 can be fixedly connected to the lower end of the outside of the drawer-type bottom box 6. A valve is installed on the water outlet pipe 7. When the valve is opened, the liquid inside the drawer-type bottom box 6 can be discharged through the water outlet pipe 7.

[0026] A filter plate 8 can also be fixedly connected inside the drawer-type bottom box 6, and solid-liquid separation can be achieved through the filter plate 8.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
