Description

Technical Field

[0001] This utility model relates to the field of high-purity gold target cleaning technology, and in particular to a high-purity gold target cleaning device. Background Technology

[0002] Cleaning high-purity gold targets is a crucial step in ensuring their performance and quality. Current methods for cleaning these metal targets involve manual grinding using an electric abrasive. Therefore, a target grinding and cleaning machine (publication number CN220548100U) is proposed. The machine's internal drive unit starts operating, rotating a speed sensor. A connector on the upper surface of the speed sensor is fixedly connected to the grinding chamber. As the grinding chamber rotates, the targets inside rub against each other. Water is introduced through the inlet pipe into the grinding chamber. The friction between the targets within the grinding chamber generates high temperatures, which are cooled by the water. When a water flow sensor detects excessive water flow, an alarm is triggered. Pressing the control panel activates the water pump, which draws water through the drain pipe into a drain tank.

[0003] However, the grinding chamber is fixedly connected to the drain pipe, and a drain box is installed on the back of the drain pipe. There is no relative movement between the drain pipe and the grinding chamber, but this fixed connection method may cause the drain pipe to get tangled when the grinding chamber rotates, which can easily cause the drain pipe to tear and break. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-purity gold target cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-purity gold target cleaning device, comprising a grinding chamber and an outer cylinder, wherein a bearing is coaxially distributed at the center of the inner bottom of the outer cylinder, the grinding chamber is disposed inside the outer cylinder and coaxially distributed with the bearing, the outer bottom of the grinding chamber is fixedly connected to the outer ring side of the bearing, a retaining ring coaxially disposed with the bearing is fixedly installed near the edge of the inner bottom of the outer cylinder, and an annular water storage tank is formed between the outer side of the retaining ring and the inner wall of the outer cylinder, a switch valve located in the water storage tank is installed through the bottom of the grinding chamber, and a drain pipe is installed on the bottom edge of the outer cylinder wall.

[0006] Preferably, the inner ring of the bearing extends downward and is fixedly connected to the bottom of the inner side of the outer cylinder. A motor is fixedly installed at the center of the bottom of the inner side of the outer cylinder, and the main shaft of the motor is connected to the center of the bottom of the outer side of the grinding chamber via a cross coupling.

[0007] Preferably, a water inlet pipe is provided on the outer cylinder wall near the top edge.

[0008] Preferably, an upwardly retractable electric push rod is also fixedly installed on the outer wall of the outer cylinder. A connecting frame extending into the grinding chamber is fixedly installed at the telescopic end of the electric push rod, and a filter plate coaxially arranged with the grinding chamber is fixedly installed at the bottom edge of the connecting frame.

[0009] Preferably, the filter plate is tapered and its edge is slidably connected to the inner wall of the grinding chamber, and the bottom edge of the filter plate is in clearance fit with the bottom of the grinding chamber.

[0010] Preferably, the connecting frame is fixedly mounted with a plurality of grinding rods distributed from top to bottom for contacting the pure gold target material.

[0011] Preferably, the outer cylinder wall has several through slots located below the top opening of the grinding chamber, and the through slots are arranged in a ring array about the central axis of the outer cylinder, and the outer cylinder wall is fixedly fitted with an annular cover that communicates with the through slots.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a retaining ring, an annular water storage tank is formed between the outer side of the retaining ring and the inner wall of the outer cylinder. When the grinding chamber is rotating and draining water, the excess water in the grinding chamber can be discharged downward and collected in the water storage tank by opening the switch valve. Finally, it is discharged through the drain pipe. During the drainage process, the switch valve revolves in the water storage tank along with the rotation of the grinding chamber. Since there is no contact between the switch valve and the water storage tank, it will not affect the rotation of the grinding chamber.

[0014] 2. In this utility model, after cleaning, the electric push rod extends and pushes the connecting frame to raise the filter plate to the same height as the top opening of the grinding chamber. The slope of the filter plate surface facilitates the pure gold target material that has been separated from the cleaning water to slide down to all sides and finally enter the annular cover through several channels. The material is then discharged through the downward-facing opening of the annular cover. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, a high-purity gold target cleaning device includes a grinding chamber 6 and an outer cylinder 1. A bearing 13 is coaxially distributed at the center of the inner bottom of the outer cylinder 1. The grinding chamber 6 is disposed inside the outer cylinder 1 and coaxially distributed with the bearing 13. The outer bottom of the grinding chamber 6 is fixedly connected to the outer ring side of the bearing 13, and the inner ring side of the bearing 13 extends downward and is fixedly connected to the inner bottom of the outer cylinder 1. The bearing 13 ensures the fixed position of the grinding chamber 6 within the outer cylinder 1. Similarly, the independent rotation of the inner and outer rings of the bearing 13 does not affect the rotation of the grinding chamber 6 within the outer cylinder 1, thus achieving the cleaning of the pure gold target material poured into it. A bearing 13 is fixedly installed near the edge of the inner bottom of the outer cylinder 1. A retaining ring 15 is coaxially arranged with the bearing 13. An annular water storage tank 12 is formed between the outer side of the retaining ring 15 and the inner wall of the outer cylinder 1. A switch valve 11 is installed through the bottom of the grinding chamber 6 and located in the water storage tank 12. A drain pipe 8 is installed on the bottom edge of the outer cylinder 1. When the grinding chamber 6 rotates and drains water, the switch valve 11 is opened to allow excess water in the grinding chamber 6 to be discharged downward and collected in the water storage tank 12, and finally discharged through the drain pipe 8. During the drainage process, the switch valve 11 revolves in the water storage tank 12 along with the rotation of the grinding chamber 6, and there is no contact between the switch valve 11 and the water storage tank 12, so it will not affect the rotation of the grinding chamber 6.

[0023] A motor 14 is fixedly installed at the center of the bottom of the inner side of the outer cylinder 1. The main shaft of the motor 14 is connected to the center of the bottom of the outer side of the grinding chamber 6 through a cross coupling. A water inlet pipe 5 is provided on the wall of the outer cylinder 1 near the top edge. The grinding chamber 6 is driven by the motor 14 to rotate and clean the pure gold target. The water inlet pipe 5 facilitates the use of a water pump by personnel, and the water pump is connected to the water inlet pipe 5 to facilitate the flow of cleaning water into the grinding chamber 6.

[0024] An upwardly retractable electric push rod 3 is fixedly installed on the outer wall of the outer cylinder 1. A connecting frame 4 extending into the grinding chamber 6 is fixedly installed at the telescopic end of the electric push rod 3. The connecting frame 4 can be raised or lowered by telescopically extending the electric push rod 3. A filter plate 10 coaxially arranged with the grinding chamber 6 is fixedly installed on the bottom edge of the connecting frame 4. The filter plate 10 is conical and its edge is slidably connected to the inner wall of the grinding chamber 6. The bottom edge of the filter plate 10 is in clearance fit with the bottom of the grinding chamber 6. Several grinding rods 9 distributed from top to bottom and used to contact the pure gold target are fixedly installed on the connecting frame 4. When the filter plate 10 is located in the grinding chamber 6, the rotation of the grinding chamber 6 can make the pure gold target inside rotate and pass through several grinding rods 9. The pure gold target can be cleaned by mutual collision and friction and contact friction with the grinding rods 9. The gap left between the filter plate 10 and the bottom of the grinding chamber 6 facilitates the accumulation of impurities that fall during the cleaning process and will not contact the pure gold target.

[0025] The outer cylinder 1 has several through grooves 7 located below the top opening of the grinding chamber 6. These through grooves 7 are arranged in a ring array about the central axis of the outer cylinder 1, and an annular cover 2, which communicates with the through grooves 7, is fixedly installed on the outer cylinder 1. After cleaning, the electric push rod 3 extends and pushes the connecting frame 4 to raise the filter plate 10 to the same height as the top opening of the grinding chamber 6. The slope of the filter plate 10 facilitates the pure gold target material that has been removed from the cleaning water to slide down to all sides and finally enter the annular cover 2 through the through grooves 7. The material is then discharged through the downward-facing opening of the annular cover 2. In addition, in this design, the inner wall of the outer cylinder 1 extends inward from the bottom edge of the through grooves 7 and is rotatably connected to the outer wall of the grinding chamber 6. The extension ensures that the sliding pure gold target material will not fall to the bottom of the inner cylinder of the outer cylinder 1.

[0026] Working principle: When in use, the pure gold target is poured into the grinding chamber 6. Driven by the motor 14, the grinding chamber 6 rotates. A certain amount of cleaning water is added to the grinding chamber 6 through the water inlet pipe 5. The pure gold target is cleaned by the rotation of the grinding chamber 6. When the grinding chamber 6 drains water during rotation, the switch valve 11 is opened to allow excess water in the grinding chamber 6 to be discharged downwards and collected in the water storage tank 12, and finally discharged through the drain pipe 8.

[0027] The wiring diagrams of the electric push rod 3, the switching valve 11, and the motor 14 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric push rod 3, the switching valve 11, and the motor 14 will not be explained in detail.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
