Description

Technical Field

[0001] The present application relates to the technical field of particle washing equipment, and in particular to a washing device and a washing method for preparing cuprous chloride by dry method. Background Art

[0002] The main raw materials for preparing cuprous 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 cuprous chloride solid. The collected cuprous chloride solid is washed with deionized water or ethanol solvent to remove impurities and residues on the surface. However, in the process of washing cuprous chloride with the existing equipment, the particle size of the prepared cuprous chloride solid is small, which leads to small friction between the particles during washing, making it difficult to remove the stubborn impurities and residues on the outer surface of the cuprous chloride. The washing efficiency is low and the effect is poor, which seriously affects the purity of the prepared cuprous chloride solid.

[0003] Therefore, there is an urgent need for a washing device for cuprous chloride solid particles to solve the defects of the above-mentioned existing washing equipment during actual use. Summary of the invention

[0004] The present application proposes a washing device and a washing method for preparing cuprous chloride by a dry process, which have the advantages of effectively improving the mutual friction between cuprous chlorides, so that the washing efficiency of cuprous chloride is higher, the effect is better, and the purity of the prepared cuprous chloride is higher. The invention is used to solve the problem that in the process of washing cuprous chloride with existing equipment, the particle size of the prepared cuprous chloride solid is smaller, which leads to the smaller mutual friction during washing, making it difficult to remove the stubborn impurities and residues on the outer surface of the cuprous chloride, resulting in low washing efficiency and poor effect, and the purity of the prepared cuprous chloride solid is lower.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a washing device for preparing cuprous chloride by dry method, comprising an outer shell that can be fixedly installed on the ground by bolts, an inner valve core is provided at the top of the inner cavity of the outer shell, and the outer shell and the inner valve core are connected by a transmission connection via an elastic member provided at the top of the inner valve core, a feed pipe connected to the middle of the inner cavity of the outer shell is fixedly installed at the top of the inner valve core, and the top of the feed pipe is connected to a cuprous chloride solid particle conveying system, and then the cuprous chloride solid particles to be washed can be conveyed to the inner cavity of the outer shell through the feed pipe for washing operation, a partition end plate is provided in the middle of the inner cavity of the outer shell, and the inner cavity of the outer shell is divided into an upper chamber and a lower chamber by the partition end plate, The inner valve core is arranged in the upper chamber on the outer shell and is connected to the outer shell through a transmission connection with an elastic member. Initially, under the elastic force of the elastic member, the top end of the partition end plate and the bottom end of the inner valve core are tightly fitted together. When the cuprous chloride is washed, the cuprous chloride solid particles are squeezed and transported to the gap between the partition end plate and the inner valve core through a feed pipe and the elastic member is compressed. An outer annular groove connected to the upper chamber is provided in the middle of the outer surface of the outer shell. The upper chamber and the lower chamber are connected through a filter hole provided on the partition end plate. A pump group whose input end is connected to the upper and lower chambers of the outer shell is fixedly installed at the bottom end of the outer shell, and the output end of the pump group is connected to the top of the partition end plate through a connecting pipe.

[0006] Furthermore, the top end of the partition end plate is provided with a concave curved surface structure, and the bottom end of the inner valve core is provided with a curved surface structure matching therewith, so that the gap track formed between the partition end plate and the inner valve core can be extended upward, so as to effectively increase the time and intensity of the mutual friction of the cuprous chloride solid particles located in the gap when the deionized water or ethanol solvent flows, so that the washing efficiency of the cuprous chloride is higher and the effect is better.

[0007] Furthermore, a straight hole extending vertically through the inner valve core is provided inside the inner valve core, and the top end of the straight hole is connected to a feed pipe, and an inner guide rod is provided inside the straight hole, and a baffle with a curved structure matching the bottom end of the inner valve core is fixedly installed on the bottom end of the inner guide rod, and the inner guide rod is elastically connected to the inner valve core through an elastic strip fixedly installed on the straight hole. The arrangement of the straight hole and the baffle on it can effectively prevent deionized water or ethanol solvent from being squeezed and transported into the straight hole, and when cuprous chloride solid particles are squeezed and transported to the straight hole through the feed pipe, the inner guide rod can be forced to move downward under the extrusion of cuprous chloride and stretch the elastic strip to connect to the straight hole, thereby ensuring the normal transportation operation of cuprous chloride.

[0008] Furthermore, a group of partitions arranged in an annular structure are provided at the bottom of the inner cavities of the upper and lower chambers of the outer shell, and a group of normally closed discharge pipes are provided on one side of the bottom end of the outer shell and between the partition and the lower chamber, and the input end of the pump group is located on the inner side of the partition, so that a group of sedimentation tanks can be formed in the lower chamber through the partition to precipitate impurities and residues carried in the deionized water or ethanol solvent and discharge them through the discharge pipe.

[0009] Furthermore, the connecting end surface between the outer ring groove and the outer side of the partition end plate is set as a slope structure, which can effectively improve the filtering effect on cuprous chloride solid particles and make it less likely to be blocked during the flow process.

[0010] Furthermore, a group of compensation pipelines are provided at the input end of the pump group and are connected to an external deionized water or ethanol solvent storage system, thereby compensating for the loss of deionized water or ethanol solvent during the operation of the washing device.

[0011] A washing method for a washing device for preparing cuprous chloride by dry method, comprising the following steps: S1. When the cuprous chloride solid particle conveying system is started, cuprous chloride enters the straight hole through the feed pipe, and squeezes the baffle at the bottom of the inner guide rod to move downward and stretch the elastic strip, so that the cuprous chloride solid particles in the straight hole enter the gap formed by the inner valve core and the partition end plate, and force the inner valve core to move upward to compress the elastic member; S2, start the pump group and squeeze the deionized water or ethanol solvent through the compensation pipeline and the connecting pipe to the gap formed by the inner valve core and the partition end plate, thereby impacting the cuprous chloride solid particles therein, and under the dual effects of the impact of the deionized water or ethanol solvent and the extrusion of the elastic member, the cuprous chloride solid particles located in the gap between the partition end plate and the inner valve core rub against each other and move along the trajectory of the gap; S3, when the washed cuprous chloride solid particles flow through the inclined surface between the outer ring groove and the partition end plate, the cuprous chloride solid particles are filtered out by the filter holes and flow into the outer ring groove, while the deionized water or ethanol solvent flows into the lower chamber to be recycled; S4. Open the discharge pipe regularly to remove impurities and residues carried by deionized water or ethanol solvent that are precipitated in the sedimentation pool formed by the partition in the lower chamber, so as to prevent the precipitated impurities and residues from entering the inner side of the partition in excess and being transported to the cuprous chloride located in the gap between the inner valve core and the partition end plate during the circulation of the deionized water or ethanol solvent.

[0012] The beneficial effects of the present invention are as follows: The present application provides a washing device and a washing method for dry-process preparation of cuprous chloride. With respect to the arrangement of the structure on the outer shell, under the dual effects of the impact of deionized water or ethanol solvent and the extrusion of the elastic member, the cuprous chloride solid particles located in the gap between the partition end plate and the inner valve core rub against each other and move along the trajectory of the gap, and effectively increase the time and intensity of the mutual friction of the cuprous chloride solid particles located in the gap as the deionized water or ethanol solvent flows, so that the washing efficiency and effect of the cuprous chloride solid particles are higher, and the purity of the preparation of the cuprous chloride solid particles is higher.
