Description

Technical Field

[0001] The present application relates to the technical field of powder material filtering equipment, and in particular to a filtering device for dry preparation of copper chloride and a filtering method thereof. Background Art

[0002] The main raw materials for preparing cupric chloride by dry method include high-purity copper powder and chlorine gas. Under high temperature and appropriate pressure conditions, a chemical reaction occurs between the copper element and the chlorine gas to generate cupric chloride gas, which is then gradually cooled to form cupric chloride crystals. The solvent and residual impurities are removed through filtering, washing and drying to obtain high-purity cupric chloride crystals.

[0003] However, during the operation of the existing filtering device, the impurities filtered out cannot be cleaned up in time, and as a large amount of impurities gather, the filtering effect of the filtering device on the copper chloride crystals is greatly affected. The accumulation of too many impurities can easily cause the clogging of the filter mesh, further affecting the filtering effect of the filtering device on the copper chloride crystals, and the stability and reliability are low.

[0004] Therefore, there is an urgent need for a filtering device for preparing cupric chloride crystals to solve the defects of the above-mentioned existing filtering devices in the actual operation process. Summary of the invention

[0005] The present application proposes a filtering device for dry preparation of copper chloride and a filtering method thereof, which have the advantages of being able to clean up the filtered impurities in time, thereby avoiding the large amount of impurities gathering and affecting the filtering effect of the filtering device on copper chloride crystals, and not causing the filter mesh to be blocked due to the large amount of impurities gathering, and are used to solve the problem that during the operation of the existing filtering device, the impurities filtered on it cannot be cleaned up in time, and then the filtering effect of the copper chloride crystals is greatly affected by the gathering of a large amount of impurities, and the gathering of too many impurities is also very likely to cause the filter mesh to be blocked.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a filtering device for dry preparation of copper chloride, comprising a shell component, the bottom of the inner cavity of the shell component is connected to a negative pressure pump station, and when the negative pressure pump station is triggered, the inner cavity of the shell component can be pumped into a negative pressure state, the inner cavity of the shell component is movably sleeved with a filter component for filtering copper chloride crystals, one end of the filter component extends to one side of the outside of the shell component, and is fixedly connected to an external driving device, and under the action of the driving device, the filter component can be driven to rotate, the inner cavity of the filter component is provided with a feeding component with one end extending to the other side of the outside of the shell component, and the copper chloride crystals are transported to the inner cavity of the filter component through the feeding component for filtering, the shell component comprises an outer shell whose bottom of the inner cavity is connected to the negative pressure pump station, a baffle is fixedly installed on one side of the inner cavity of the outer shell, and an assembly hole is opened inside the baffle;

[0007] The filter assembly includes a frame movably sleeved in the inner cavity of the outer shell, and one end of the frame is in contact with the baffle, and a transmission shaft extending to the outside of the shell component is fixedly installed on the side end of the frame, and is connected to the driving device through the transmission shaft. The outer surface of the frame is provided with a filter bag for filtering copper chloride crystals, and then under the action of the negative pressure pump station, negative pressure is formed in the inner cavity of the shell component and the periphery of the filter bag, while improving the filtering effect of the filter bag on copper chloride crystals, the filtered impurities can be adsorbed on the inner wall of the filter bag and driven to rotate, and when it rotates to the highest point, under the action of gravity, the filter bag at the top position bends inwards, and the impurities adsorbed on the inner wall of the filter bag are shaken off;

[0008] The feeding component includes an L-shaped conveying pipe for conveying copper chloride crystals, one end of the conveying pipe extends to the middle of the frame cavity, and the other end of the conveying pipe extends to the outside of the shell component. The outer surface of the conveying pipe is provided with a discharge plate for carrying falling impurities, which passes through the assembly hole and extends to the outside of the shell component, and the filtered impurities are discharged in time through the discharge plate.

[0009] Furthermore, one end of the conveying pipe extends to the inner end surface of the frame, and a through hole connected to its inner cavity is opened in the middle of one side of the bottom end of the conveying pipe. At the same time, the discharge plate on the conveying pipe extends to the inner end surface of the frame and contacts the inner end surface of the frame.

[0010] Furthermore, the filter bag is made of a flexible material, and under the action of the frame, the filter bag is equally divided into several areas, and then under the action of negative pressure adsorption, the lower half of the filter bag bulges outward, and when the filter bag rotates and moves to the highest point, under the action of gravity, this part of the filter bag bends inward to ensure that the bending direction of the filter bag can be reversed to shake off the impurities adsorbed on its inner wall, and in the process of bending and reversing, the filter mesh holes on the filter bag can be effectively prevented from being blocked.

[0011] Furthermore, a group of counterweight blocks are provided in the middle of the filter bag which is divided into several areas. When the area rotates and moves to the highest point, under the action of gravity, the filter bag in the area overcomes the negative pressure adsorption force of the negative pressure pump station and bends inward under the influence of gravity.

[0016] S2. In the process of filtering copper chloride crystals with filter bags, the impurity particles are adsorbed on the inner wall of the filter bag due to their large size, and the impurities are carried and rotated to the highest point during the rotation of the filter bag;

[0017] S3. When a certain area of ​​the filter bag rotates and moves to the highest point, under the action of gravity, the filter bag in this area bends inwards, so as to bend and reverse, and the impurities adsorbed on the inner wall are shaken off to the discharge plate;

[0018] S4. Afterwards, due to the inclined arrangement of the discharge plate, the impurities falling onto it are discharged to the outside of the outer shell, and during the continuous rotation of the filter bag, the filter bag in a certain area bent inward is bulged again due to negative pressure adsorption, so that the copper chloride crystals are filtered reciprocally and the filtered impurities are discharged at the same time.

[0019] The beneficial effects of the present invention are as follows:
