Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to an acid liquid removing device for a negative pressure pipe of a cap machine. Background Technique

[0002] In the production process of lead-acid batteries, there is a key acid addition process. The lead-acid batteries use negative pressure acid addition. First, the inside of the battery is sucked to a negative pressure state, and then the pipeline is switched to inject the electrolyte into the battery, which is beneficial to the full injection of the battery.

[0003] When the production process of lead-acid batteries is completed after processes such as acid injection, battery formation, and acid pumping, a cap machine is also used to install caps on the top of the battery case to protect the exposed electrodes. Among them, each time the cap machine installs a cap, it will suck the excess acid on the battery surface; and the sucked acid liquid will corrode the vacuum pump inside the cap machine, which may cause the performance of the vacuum pump to decline, and in the long term, it will even affect its normal operation; it may even form sediments inside the pump, resulting in blockage and damage of the pump. In view of the problem that the sucked acid liquid will corrode the inside of the vacuum pump pointed out above, the present invention designs an acid liquid removing device for a negative pressure pipe of a cap machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide an acid liquid removing device for a negative pressure pipe of a cap machine. Through the functions of a housing, an acid liquid gathering cap, and a ventilation hole designed in the acid liquid removing device, the sucked acid liquid is gathered and attached to the acid liquid gathering cap, and then flows into the inner bottom of the housing from the edge or overflow channel of the acid liquid gathering cap, and it is not easy to enter the inside of the vacuum pump through the ventilation hole; the problem of acid liquid corroding internal equipment is greatly avoided.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model relates to an acid liquid removal device for a negative pressure pipe of a leather cap machine, which comprises an acid liquid removal device, a negative pressure pipe and a vacuum pump. The negative pressure pipe is fixedly communicated with the vacuum pump. The acid liquid removal device comprises an acid liquid filtering component, a first negative pressure pipe connection port and a second negative pressure pipe connection port. The two end ports of the acid liquid filtering component are respectively fixedly provided with the first negative pressure pipe connection port and the second negative pressure pipe connection port. The first negative pressure pipe connection port is fixedly communicated with the negative pressure pipe, and the second negative pressure pipe connection port is fixedly communicated with the air inlet of the vacuum pump. The acid liquid filtering component comprises a housing and an acid liquid gathering cap. The inner end part of the first negative pressure pipe connection port extends into the housing. The acid liquid gathering cap is fixedly installed inside the housing. The outer end part of the acid liquid gathering cap is fixedly connected with the second negative pressure pipe connection port. The circumferential side surface of the acid liquid gathering cap is evenly provided with ventilation holes. After the acid liquid is sucked into the negative pressure pipe, it enters the interior of the acid liquid filtering component. Since the density and mass of the acid liquid are larger than those of the gas, the acid liquid is extremely easy to hit the inner end surface of the acid liquid gathering cap along with the airflow. While the gas can easily bypass the acid liquid gathering cap and enter the air inlet of the vacuum pump through the ventilation holes, thus realizing the function of removing acid liquid to a great extent.

[0007] As a preferred technical solution of the utility model, a plurality of baffle rings and ventilation holes are evenly arranged in an array on the outer end of the housing at the acid liquid gathering cap; the design of adding a plurality of baffle rings and ventilation holes improves the flow efficiency of the gas under the negative pressure, and relatively reduces the resistance of the acid liquid removal device to the gas flow.

[0008] As a preferred technical solution of the utility model, baffle grooves are arranged at the edges of the inner end surfaces of the acid liquid gathering cap and the baffle rings; the baffle grooves concentrate the gathered acid liquid, making it not easy to flow along the inner end surfaces of the acid liquid gathering cap and the baffle rings to their edges, and then making it not easy for the acid liquid to float into the ventilation holes, thus achieving the effect of filtering the acid liquid.

[0009] As a preferred technical solution of the utility model, an overflow channel is fixedly connected to the circumferential side surface of the baffle groove; the overflow channel enables the acid liquid located at the center of the housing to flow to the inner wall of the housing and not easy to float into the ventilation holes.

[0010] As a preferred technical solution of the utility model, the ventilation holes are located at the inner side position of the outermost edge of the acid liquid gathering cap.

[0011] As a preferred technical solution of the utility model, an acid liquid baffle plate is fixed on the side of the ventilation hole close to the first negative pressure pipe connection port; the acid liquid baffle plate further hinders the acid liquid from floating into the ventilation hole, and has the effect of improving the filtering of the acid liquid.

[0012] As a preferred technical solution of the present utility model, a bottle body for storing acid solution is fixedly communicated with the peripheral side surface of the outer shell. A drain port is further provided on the bottle body, and a bottle cap is hermetically threadedly connected to the drain port; when the accumulated acid solution in the bottle body tends to be full, it is convenient to perform acid drainage treatment.

[0013] The present utility model has the following beneficial effects:

[0014] Through the functions of the outer shell, the acid solution aggregation cap and the ventilation hole designed in the acid solution removal device of the present utility model, the inhaled acid solution is gathered and attached to the acid solution aggregation cap, and then flows into the inner bottom of the outer shell from the edge or the overflow channel of the acid solution aggregation cap, and it is not easy to enter the internal part of the vacuum pump through the ventilation hole; it has the advantages of preventing acid solution corrosion and protecting internal equipment, and to a great extent, avoids the effect of acid solution corroding internal equipment.

[0015] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

The circumferential side of the acid liquid aggregation cap 1012 is evenly provided with vent holes 1013; after the acid liquid is sucked into the negative pressure pipe 2, it enters the inner part of the acid liquid filtration component 101. Since the density and mass of the acid liquid are relatively large compared with the gas, the acid liquid is very likely to hit the inner end face of the acid liquid aggregation cap 1012 along with the airflow; while the gas can easily bypass the acid liquid aggregation cap 1012 and enter the air inlet of the vacuum pump through the vent holes 1013; thus realizing the function of removing acid liquid to a large extent; the vent holes 1013 are located at the inner side position of the outermost edge of the acid liquid aggregation cap 1012.
