Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to a cleaning device for barley before processing. Background Technology

[0002] Barley is a plant that grows in high-altitude areas. After harvesting, it is threshed to obtain barley grains, which can be processed into barley flour, barley noodles, etc., and are used as a staple food for residents in high-altitude areas.

[0003] Before processing, barley grains need to be washed to remove dust adhering to their surface. Patent CN220901000U discloses a barley washing device, including a processing box with a cavity inside. A feed hopper communicating with the cavity is located on the upper surface of the processing box. A discharge port is opened on the side wall of the cavity. A vibrating screen plate with one end extending from the discharge port is located inside the cavity. A vibration assembly for driving the screen plate is located inside the cavity. A washing box connected to the processing box is located at the discharge port. The washing box has a washing chamber with an opening communicating with the discharge port. A circular hole is opened on the bottom wall of the washing chamber, and a conical tube communicating with the washing chamber is located inside the circular hole. A discharge pipe is located at the bottom of the conical tube, and a drainage assembly is located inside the discharge pipe. The existing method uses a vibrating assembly to impact a screen plate to screen impurities mixed in with the barley, removing dust particles, small stones, etc., and then separates the barley from the wastewater by passing it through a filter plate installed at the discharge pipe. While this method can remove dust particles and small stones mixed in with the barley, it cannot remove the husks and other impurities. This results in the husks remaining in the washed barley, leading to poor cleaning efficiency and affecting the quality of subsequent barley product processing. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a barley pre-processing cleaning device that can remove husks and other impurities from the barley during the cleaning process, thereby improving the cleaning effect.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed: A barley pre-processing cleaning device is installed at the discharge end of a screening device. It includes a cleaning tank, a discharge pipe at the lower end of the cleaning tank, a switch valve on one side of the discharge pipe, a feed pipe at the upper end of the cleaning tank, and a stirring assembly inside the cleaning tank. The stirring assembly includes a rotating shaft coaxially rotatable inside the cleaning tank, a sleeve coaxially mounted outside the rotating shaft, floats arranged in a circumferential array around the outer circumference of the sleeve, a through groove on one side of the float, a mesh bag fitted at one end of the through groove, and the other end aligned with the rotation direction of the rotating shaft. A stirring paddle is provided at the lower end of the rotating shaft.

[0006] Furthermore, the length of the float plate is consistent with the radial direction of the cleaning tank. The float plate has an inverted L-shaped structure with the inner right angle facing upwards. The horizontal part of the float plate is connected to the outer wall of the sleeve, and the through groove is inclined. Its upper end is connected to one side of the horizontal part, and its lower end is connected to one end of the vertical part.

[0007] Furthermore, the vertical part of the float is provided with an annular groove, and the opening of the net bag is provided with an elastic ring, which is fitted into the annular groove.

[0008] Furthermore, the upper end of the rotating shaft passes through the cleaning tank and connects to a motor located on top of the cleaning tank.

[0009] Furthermore, the lower end of the cleaning tank has an inverted conical structure, and the outer side of the agitator is adapted to the inner wall of the lower end of the cleaning tank.

[0010] Furthermore, the shaft has a square cross-section, and the sleeve has a square tubular structure.

[0011] The beneficial effects of this utility model are as follows: A sleeve is coaxially fitted outside the rotating shaft, and a float plate is placed outside the sleeve. During the barley washing process, the float plate floats on the water surface. The rotating shaft drives the sleeve to rotate, so that the husks floating on the water surface enter the mesh bag along the channel for collection. This prevents the husks from being mixed into the barley again during the barley washing process and improves the washing effect. Attached Figure Description

[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-4 As shown, this embodiment improves a barley pre-processing cleaning device, which is located at the discharge end of the barley screening equipment. The cleaning device includes a cleaning tank 1 and a stirring component 2, which is used to clean the barley to remove the husks mixed in the barley and the dust attached to the surface of the barley, so as to avoid affecting the taste of the macaroni when the barley is processed.

[0020] Specifically, such as Figure 1 As shown, the washing tank 1 has a cylindrical structure with an inverted conical structure at its lower end. A discharge pipe 11 is vertically downward at the lower end of the inverted conical structure, and a material collection mesh frame is correspondingly provided at the lower end of the discharge pipe 11. A switch valve 12 is provided on one side of the discharge pipe 11. The outer wall of the inverted conical structure is vertically provided with support legs arranged in a circumferential array. A feed pipe 13 is provided on one side of the upper end of the washing tank 1. The feed pipe 13 is used to connect to the discharge end of the screening equipment.

[0021] like Figures 1-2 As shown, the stirring assembly 2 is vertically installed inside the washing tank 1 to agitate the barley entering the washing tank 1, thereby improving washing efficiency and ensuring washing effect. The stirring assembly 2 includes a rotating shaft 21, a sleeve 22, a float 23, a stirring paddle 24, and a motor 25. The output end of the motor 25 is vertically downward installed at the upper end of the washing tank 1. The output end of the motor 25 is provided with a drive shaft connected to the rotating shaft 21. The rotating shaft 21 is coaxially installed inside the washing tank 1, and the sleeve 22 is coaxially fitted outside the rotating shaft 21.

[0022] Multiple floats 23 are arranged in a circumferential array along the outer periphery of the sleeve 22. The density of the floats 23 is less than that of water. In this embodiment, two floats are provided. The upward buoyancy of the two floats 23 is greater than the downward vertical weight of the sleeve 22, so that the floats 23 and the sleeve 22 are always kept on the water surface. The length direction of the floats 23 is consistent with the radial direction of the washing tank 1. A through groove 231 is provided along the length direction of the floats 23. The two sides of the through groove 231 are respectively connected to the two sides of the floats 23. The through groove 231 is inclined. Its upper end is consistent with the rotation direction of the rotating shaft 21. A net bag 232 is fitted on the lower end so that the rice husks floating on the water surface can enter the net bag 232 along the through groove 231 for collection.

[0023] The stirring paddle 24 is located at the lower end of the rotating shaft 21, and the outer side of the stirring paddle 24 is provided with an inclined surface that is adapted to the inverted conical structure at the lower end of the washing tank 1. This is used to stir the barley during the washing process to improve the washing efficiency and ensure the washing effect.

[0024] Preferred, such as Figure 3As shown, the cross-section of the rotating shaft 21 is square, and the inner wall of the cross-section of the sleeve 22 is adapted to the shape of the outer wall of the cross-section of the rotating shaft 21, so that the rotating shaft 21 can rotate while driving the sleeve 22 to rotate synchronously, so that the sleeve 22 can drive the float 23 to rotate.

[0025] Preferred, such as Figure 4 As shown, in order to increase the buoyancy of the float plate 23, the cross-section of the float plate 23 is set in an inverted L-shaped structure, with its vertical part set horizontally and its horizontal part connected to the outer wall of the sleeve 22, so that the vertical part of the float plate 23 contacts the water surface, thereby increasing the contact area between the float plate 23 and the water surface.

[0026] In a further preferred embodiment, to facilitate the disassembly of the net bag 232, an annular groove is provided on the outer periphery of the vertical part of the float 23, and an elastic ring 233 is provided at the opening of the net bag 232, so that the elastic ring 233 is fitted into the annular groove.

[0027] The specific operation process is as follows: Keep valve 12 closed, feed the screened barley into the washing tank 1 through feed pipe 13, and then inject water into the washing tank 1 through feed pipe 13. Start motor 25 to drive shaft 21 to rotate, thereby causing agitator 24 to agitate the barley, causing the husks on the barley to float to the surface and the dust attached to the barley to detach. As shaft 21 rotates, sleeve 22 drives float plate 23 to rotate synchronously and collect the husks and other impurities floating on the water surface. After washing, open valve to discharge the washed barley and collect it through collection mesh frame to prevent husks from entering the washed barley.

[0028] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
