Description

Technical Field

[0001] This utility model belongs to the technical field of quartz sand pickling equipment, and particularly relates to a quartz sand pickling device. Background Technology

[0002] The process of preparing quartz sand includes sand making, acid washing, drying, and agitation, among which acid washing is used to remove impurities from the quartz sand. To improve acid washing efficiency, manufacturers often use acid washing equipment for this step; however, the efficiency of most of these methods is still not ideal and needs further improvement. For example, patent document CN202520649534.0 discloses an acid washing device including an acid washing tank, a tank cover, a servo motor, and a drive shaft. The drive shaft passes through the tank cover and enters the interior of the acid washing tank. Several transverse stirring rods and other components are installed at different heights on the side of the drive shaft, which can agitate the quartz sand during the acid washing process and cover a larger stirring area; however, it can only agitate the quartz sand at the height of the transverse stirring rods, and the acid washing efficiency still needs improvement. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a quartz sand pickling device that can continuously agitate the quartz sand during the pickling process to improve pickling efficiency.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: A quartz sand pickling device includes a tank with a cover plate on top and an inverted conical structure at the bottom. An acid spraying assembly is coaxially mounted on the tank. The tank is equipped with a discharge pipe at the bottom, a switch valve at the connection between the discharge pipe and the tank, a liquid outlet pipe at the bottom of the discharge pipe, a filter screen at the connection between the liquid outlet pipe and the discharge pipe, and a feeding pipe on the top surface of the cover plate. The pickling spraying assembly includes an inlet pipe that is coaxially rotatably mounted inside the tank, with the upper end of the inlet pipe passing through a cover plate. Multiple layers of distributing pipes arranged in a circumferential array are provided along the outer periphery of the inlet pipe, and a spray nozzle is provided on one side of each distributing pipe. A spiral-structured baffle is provided on the lower side of each distributing pipe.

[0005] Furthermore, a rotary joint is provided at the top of one end of the inlet pipe that passes through the cover plate. The lower end of the rotary joint is coaxially mounted on the first bevel gear, and the first bevel gear is coaxially fixed to the outer wall of the inlet pipe. A second bevel gear is meshed on one side of the first bevel gear, and the large end of the second bevel gear is coaxially connected to the output end of a motor.

[0006] Furthermore, the distribution pipes of adjacent layers are arranged in an alternating manner.

[0007] Furthermore, a stabilizing frame is provided at the connection between the lower end of the tank and the inverted conical structure. The stabilizing frame includes a convex ring that connects to the inner wall of the tank. A connecting ring is concentrically provided inside the convex ring. A connecting plate is arranged in a circumferential array between the connecting ring and the convex ring. The lower end of the liquid inlet pipe is rotatably located on the connecting ring.

[0008] Furthermore, a scraper is provided at the lower end of the inlet pipe, and the scraper is tangent to the inner wall of the inverted conical structure at the lower end of the tank.

[0009] The beneficial effects of this utility model are as follows: A distribution pipe is installed around the outer periphery of the inlet pipe, with multiple layers distributed along the outer periphery. A spray nozzle is installed on one side of the distribution pipe, and a spiral baffle is installed on the lower side of each distribution pipe. When the inlet pipe rotates, it drives the distribution pipe to rotate, thus not only agitating the quartz sand, but also accelerating the flow of the pickling solution sprayed from the spray nozzle. Combined with the spiral baffle, this agitates the quartz sand, thereby improving pickling efficiency. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] like Figures 1-5 As shown, this embodiment provides a quartz sand pickling device, including a tank 10 and a pickling spraying liquid assembly 20 disposed in the tank 10.

[0019] like Figure 1 As shown, the tank body 10 has a cylindrical structure with an inverted conical structure at the bottom and a cover plate 11 at the top. The lower end of the inverted conical structure is connected to a discharge pipe 12, and a switch valve 121 is provided at the connection between the discharge pipe 12 and the lower end of the inverted conical structure to block or connect the discharge pipe 12 and the tank body 10.

[0020] A liquid outlet pipe 13 is connected to the lower side of the discharge pipe 12 for the pickling solution to flow out, and a filter screen 131 is provided at the connection between the discharge pipe 12 and the liquid outlet pipe 13 to separate the pickling solution from the quartz sand.

[0021] The pickling spraying assembly 20 is coaxially installed inside the tank 10, and the upper end of the pickling spraying assembly 20 passes through the cover plate 11. The cover plate 11 is vertically provided with a feeding pipe 14 that connects to the inside of the tank 10 for feeding quartz sand, and the feeding pipe 14 is located on the side where the pickling spraying assembly 20 extends out of the cover plate 11.

[0022] like Figures 1-3 As shown, the pickling spray assembly 20 includes an inlet pipe 21 and a distributor pipe 22. The inlet pipe 21 is coaxially disposed inside the tank body 10. The upper end of the inlet pipe 21 passes through the cover plate 11 and is provided with a rotary joint 211 for connecting to the output end of the pickling liquid supply pump.

[0023] A first bevel gear 212 is provided below the rotary joint 211. The first bevel gear 212 is coaxially fixed on the outer periphery of the liquid inlet pipe 21, and the small end of the first bevel gear 212 faces upward. A second bevel gear 213 is meshed on one side of the first bevel gear 212. The large end of the second bevel gear 213 is connected to the output end of a motor 214, and the motor 214 is provided on the cover plate 11.

[0024] In use, the motor 214 drives the second bevel gear 213 to rotate, which in turn drives the first bevel gear 212 to rotate, thereby causing the liquid inlet pipe 21 to rotate.

[0025] The distribution pipe 22 is provided with multiple layers of 22 arranged in a circular array along the outer periphery of the inlet pipe 21, and the axial direction of the distribution pipe 22 is consistent with the radial direction of the inlet pipe 21. The distribution pipe 22 is connected to the inlet pipe 21. In order to improve the uniformity of contact between the quartz sand and the pickling solution during pickling and improve the pickling efficiency, the adjacent layers of 22 are staggered.

[0026] A spray nozzle 221 is horizontally provided on one side of the dispensing pipe 22, perpendicular to the length direction of the dispensing pipe 22. The spray nozzles 221 are arranged in an array along the length direction of the dispensing pipe 22 so that the sprayed pickling solution can accelerate the flow of quartz sand and pickling solution, thereby further improving the pickling effect.

[0027] A spiral-structured baffle 222 is provided on the lower side of each dispensing pipe 22 so that the baffle 222 can agitate the quartz sand as the dispensing pipe 22 rotates and flips it upwards at the same time to further improve the pickling effect.

[0028] Preferred, such as Figure 2 , Figures 4-5 As shown, in order to provide stability when the inlet pipe 21 rotates, a stabilizing frame 15 is provided at the connection between the lower end of the tank body 10 and the inverted conical structure. The stabilizing frame 15 includes a convex ring 151 that connects to the inner wall of the tank body 10. A connecting ring 152 is concentrically provided inside the convex ring 151. A connecting plate 153 is arranged in a circumferential array between the connecting ring 152 and the convex ring 151. The lower end of the inlet pipe 21 is rotatably located on the connecting ring 152.

[0029] In a further preferred embodiment, in order to agitate the quartz sand at the lower conical structure of the tank body 10, a scraper 215 is provided at the lower end of the liquid inlet pipe 21, and the scraper 215 is tangent to the inner wall of the lower conical structure of the tank body 10.

[0030] In a further preferred embodiment, the side of the scraper 215 away from the inner wall of the inverted conical structure at the lower end of the tank 10 can be arranged in a spiral structure to better flip the quartz sand at the lower end of the tank 10 upwards.

[0031] 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.
