Description

Technical Field

[0001] This utility model relates to the field of copper oxide production technology, specifically to a precision filter for copper oxide production. Background Technology

[0002] In the copper oxide production process, liquid containing copper oxide particles and other impurities is passed through the inlet of a precision filter. Unreacted metal impurities or insoluble precipitates formed by the reaction are blocked. The high-purity copper oxide obtained after removing impurities is used to manufacture semiconductor materials. Therefore, the precision filter can ensure that the product meets strict quality standards.

[0003] Currently, high-purity copper oxide extraction mostly uses wet methods, which involve mixing copper oxide with the prepared solution and then filtering. However, existing precision filters are difficult to disassemble during regular maintenance because cleaning the filter screen requires disassembling a large number of screws, bolts, and other limiting components, consuming a lot of time, which is not conducive to increasing production time and reducing output within the production cycle. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a precision filter for copper oxide production, which can effectively solve the problems of difficult bolt disassembly and numerous internal filter screen disassembly steps in the existing traditional precision filter.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a precision filter for copper oxide production, including a housing. A hinge is fixedly installed on the upper side wall of the housing, and a top cover is hinged to the upper part of the hinge. An insert-type buckle is fixedly installed on the upper side wall of the housing, and the insert-type buckle is connected to the top cover buckle. A limit ring is fixedly installed on the inner wall of the housing. A nest is provided on the upper surface of the limit ring. A locator is fixedly installed on one side of the limit ring. A conical column is arranged in a ring array at the lower part of the nest. The upper end of the conical column is fixedly connected to the nest. A retaining ring is fixedly installed inside the limit ring. A filter cylinder is rotatably connected to the upper part of the limit ring. A retaining block is fixedly installed on the lower side of the retaining ring. The side of the retaining block contacts the outer surface of the conical column. A transmission mechanism is fixedly installed on one side of the upper part of the housing. An end toothed disc is fixedly installed on the outer wall of the filter cylinder.

[0007] Preferably, the positioner includes a push-pull electromagnet and a pin. The output shaft of the push-pull electromagnet passes through the interior of the positioner and is fixedly connected to a first electromagnet. A spring is provided inside the positioner. A second electromagnet is fixedly provided on one side of the spring. The other side of the second electromagnet passes through the interior of the positioner and is fixedly provided with a pin. The first electromagnet and the second electromagnet are magnetically attracted to each other.

[0008] Preferably, the transmission mechanism includes a limiting post fixedly disposed inside the housing, a motor fixedly disposed on the left side of the limiting post, a second bevel gear rotatably connected to the upper part of the limiting post, a first bevel gear fixedly disposed on the rotating shaft of the motor, the first bevel gear meshing with the second bevel gear, and a curved surface gear fixedly disposed on the other side of the second bevel gear, the outer surface of the curved surface gear meshing with the outer surface of the end gear plate.

[0009] Preferably, a sealing ring is provided at the lower end of the top cover, and the outer surface of the sealing ring is in contact with the inner surface of the top of the outer shell.

[0010] Preferably, an inclined plate is fixedly provided on the inner wall of the outer shell, and a discharge pipe is fixedly provided at the lower end of the inclined plate. The discharge pipe passes through the inner wall of the outer shell and is fixedly connected to the outer shell. An inlet pipe is fixedly provided on the top of the top cover.

[0011] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0012] This invention addresses the issue of filter cartridges needing to be disassembled for cleaning when impurities accumulate inside. A pin on the locator positions the inner wall of the nested cartridge, securing it to the limiting ring. A conical column on the nest engages with a locking block, and the other side of the locking block engages with the limiting ring to enhance its fixing effect. This allows for easy installation or removal by pulling the nest downwards or upwards, facilitating the cleaning of the filter cartridge from the limiting ring position. Furthermore, a transmission mechanism engages a toothed disc with a curved gear, generating centrifugal force to accelerate the wet preparation of copper oxide during filter cartridge rotation. This ensures the filtered solution is better ejected and converges towards the inclined plate. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 8A precision filter for copper oxide production includes a housing 1. A hinge 2 is fixedly installed on the upper side wall of the housing 1. A top cover 3 is hinged to the upper part of the hinge 2. The top cover 3 can be opened by flipping the top of the housing 1, which is convenient for inspecting and disassembling the interior of the precision filter. An insert-type buckle 4 is fixedly installed on the upper side wall of the housing 1. The insert-type buckle 4 is snapped into the top cover 3. A limit ring 19 is fixedly installed on the inner wall of the housing 1. A nest 7 is provided on the upper surface of the limit ring 19. A locator 6 is fixedly installed on one side of the limit ring 19. Two sets of locators 6 are provided to position the nest 7 placed in the groove of the limit ring 19 for initial fixed installation.

[0026] The positioner 6 includes a push-pull electromagnet 13 and a pin 17. The output shaft of the push-pull electromagnet 13 passes through the interior of the positioner 6 and is fixedly connected to a first electromagnet 14. A spring 15 is provided inside the positioner 6. A second electromagnet 16 is fixedly provided on one side of the spring 15. The other side of the second electromagnet 16 passes through the interior of the positioner 6 and is fixedly provided with a pin 17. The first electromagnet 14 and the second electromagnet 16 are magnetically attracted to each other. The position is limited by pushing the pin 17 into the nest 7 by the push-pull electromagnet 13. When the elasticity of the second electromagnet 16 fails, the magnetic attraction between the first electromagnet 14 and the second electromagnet 16 can further ensure that the pin 17 can still perform the position limiting function.

[0027] The lower annular array of the nested 7 is provided with a conical column 8, the upper end of the conical column 8 is fixedly connected to the nested 7, a retaining ring 9 is fixedly provided inside the limiting ring 19, the upper part of the limiting ring 19 is rotatably connected to the filter cylinder 5, a retaining block 10 is fixedly provided on the lower side of the retaining ring 9, the side of the retaining block 10 contacts the outer surface of the conical column 8, and the other side of the retaining block 10 contacts the surface of the concave hole of the limiting ring 19, so as to snap the nested 7 and the limiting ring 19 into a fixed connection when the conical column 8 is pressed downward. A transmission mechanism 11 is fixedly provided on one side of the upper part of the outer shell 1, and an end gear 12 is fixedly provided on the outer wall of the filter cylinder 5. The transmission mechanism 11 includes a limiting post 112 fixedly provided inside the outer shell 1, a motor 111 fixedly provided on the left side of the limiting post 112, a second bevel gear 114 rotatably connected to the upper part of the limiting post 112, and a first bevel gear 114 fixedly provided on the rotating shaft of the motor 111. A bevel gear 113 is meshed with a second bevel gear 114. A curved gear 115 is fixedly installed on the other side of the second bevel gear 114. The outer surface of the curved gear 115 meshes with the outer surface of the end gear disk 12. A motor 111 is set as the power source to drive the rotation of the end gear disk 12, so that the centrifugal force required by the filter cylinder 5 is provided by the transmission mechanism 11, ensuring good stability of the centrifugal motion. The upper part of the filter cylinder 5, which is rotatably connected to the limit ring 19, is positioned by the nest 7. Due to the positioning of the locator 6 and the snap-fit ​​connection of the locking block 10, the nest 7 can be lifted upwards without being limited by the locator 6, so that the filter cylinder 5 inside the limit ring 19 can be taken out. This replaces the effect of using a large number of screws to disassemble and remove the filter cylinder 5 inside the limit ring 19 for cleaning.

[0028] A sealing ring 18 is provided at the lower end of the top cover 3. The outer surface of the sealing ring 18 contacts the inner surface of the top of the outer shell 1. The sealing ring 18 is used to further seal the position gap between the top cover 3 and the outer shell 1 after they are closed. An inclined plate 21 is fixedly provided on the inner wall of the outer shell 1. A discharge pipe 22 is fixedly provided at the lower end of the inclined plate 21. The discharge pipe 22 passes through the inner wall of the outer shell 1 and is fixedly connected to the outer shell 1. An inlet pipe 24 is fixedly provided at the top of the top cover 3. The liquid flows in through the inlet pipe 24, filters the copper oxide, and then flows downward to the position of the inclined plate 21. The funnel-shaped design is conducive to the flow of liquid and will not stagnate in the tank.

[0029] The working principle of this utility model is as follows:

[0030] To allow for observation of the interior of the precision filter, a top cover 3 is hinged to the upper part of the hinge 2. The top cover 3 allows the top of the outer casing 1 to be opened directly by flipping it open, which facilitates the inspection and disassembly of the interior of the precision filter.

[0031] When disassembling the filter cartridge 5 after observing the situation inside the tank, the electric drive first retracts the push-pull electromagnet 13, causing the second electromagnet 16 to stretch elastically, which causes the pin 17 to no longer be inserted into the nest 7. The nest 7 loses its limiting function. Then, the nest 7 is no longer limited by the positioner 6 and is pushed upward, so that the filter cartridge 5 inside the limiting ring 19 can be taken out. This replaces the need to use a large number of screws to disassemble and remove the filter cartridge 5 inside the limiting ring 19, reducing the time spent cleaning metal impurities from the filter cartridge 5.

[0032] When the precision filter is in operation, the liquid flows into the feed pipe 24 and flows down to the inclined plate 21 after filtering copper oxide. The funnel-shaped design facilitates the flow of liquid and prevents it from stagnating in the tank.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
