Lead pump for lead acid battery production

Abstract

This utility model discloses a lead pump for lead-acid battery production, relating to the technical field of lead smelting equipment. It includes a servo motor, with a transmission rod at the output end of the servo motor and a vane pump at the end of the transmission rod. A suction pipe is located on the left side of the vane pump, and a discharge pipe is located on the right side. Compared to existing ordinary lead pumps, the separation tank allows for gas-liquid separation when the vane pump is used to transport molten lead. If the pressure inside the discharge pipe is too high, the overflowing molten lead will undergo gas-liquid separation in the separation tank. The separated molten lead will then re-enter the suction pipe for circulation, while the high-pressure gas will enter a metering pressure storage tank for storage. Furthermore, the pressure sensor allows for timely pressure replenishment through the metering pressure storage tank when the vane pump needs cleaning or when the pressure generated by the vane pump is insufficient, ensuring the normal operation of the equipment.

Description

Technical Field

[0001] This utility model relates to the technical field of lead smelting equipment, specifically a lead pump for lead-acid battery production. Background Technology

[0002] In the lead smelting and electrolytic production process, lead pumps are indispensable equipment. The main working principle of a lead pump is to drive the drive shaft to rotate, thereby driving the impeller fixed on the drive shaft to generate centrifugal force, which draws molten lead into the pump casing, and then transports the molten lead to the ingot mold through the lead delivery pipe to cool and form lead ingots. However, since existing lead pumps are generally single-outlet lead pumps, that is, lead delivery pipes are set on only one side, the pressure of the lead column in the lead delivery pipe generates a reverse radial force, which causes one-sided friction between the drive shaft and the pump casing, resulting in frequent maintenance and increased operating costs. In addition, the lead outlet of the lead pump generally uses a threaded seal connection to the lead delivery pipe. Due to the high pressure of the lead in the lead delivery pipe, and the poor firmness of the threaded seal connection, lead is prone to leakage.

[0003] For example, patent application number 201921515705.1 discloses a lead pump. This utility model provides a lead pump, which includes a motor, a mounting base, a pump mounting frame, a pump shaft, an impeller, and a pump casing. The mounting base is located on the top end face of the pump mounting frame, and the motor is fixedly connected above the mounting base. A filter cover is installed on the outside of the lead inlet at the bottom of the pump casing. It adopts a structure with symmetrical lead outlets at both ends of the pump casing to overcome the defects of the prior art that often require maintenance. It can balance the force on the pump shaft, reduce the friction between the pump shaft and the pump casing, and combine it with a flange sealing connection structure, which has a good sealing effect. The overall structure is scientific, reasonable, simple and compact, and easy to install and operate. It is widely applicable to metal smelting. However, when using this lead pump, if the pressure inside the lead liquid is too high, it will impact the mold and reduce the service life of the mold.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a lead pump for lead-acid battery production. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2 As shown, a lead pump for lead-acid battery production includes a servo motor 1. The output end of the servo motor 1 is provided with a transmission rod 101, and the end of the transmission rod 101 is provided with a vane pump 102. A suction pipe 103 is provided on the left side of the vane pump 102, and a discharge pipe 104 is provided on the right side of the vane pump 102. A pressure relief valve 2 is provided on the outer surface of the discharge pipe 104, and a connecting pipe 201 is provided on the upper surface of the pressure relief valve 2. In this technical solution, by setting the vane pump 102, suction force can be generated by rotation to draw in and discharge lead liquid.

[0023] Furthermore, a separation box 202 is provided at the end of the connecting pipe 1 201, and a connecting pipe 203 is provided on the lower left side surface of the separation box 202. A one-way valve 204 is provided at the end of the connecting pipe 203, and the one-way valve 204 is connected to the outer surface of the suction pipe 103. With this technical solution, by setting the separation box 202, if the pressure inside the discharge pipe 104 is too high when the vane pump 102 is used to transport lead liquid, the overflowing lead liquid will be separated by gas and liquid through the separation box 202. The separated lead liquid will re-enter the suction pipe 103 for circulation, while the high-pressure gas will enter the metering storage tank 205 for storage.

[0024] Furthermore, a filter assembly 200 is provided on the upper surface of the separation box 202, and a metering pressure storage tank 205 is provided at the end of the filter assembly 200. A solenoid valve 206 is provided on the outer surface of the metering pressure storage tank 205, and a connecting pipe 207 is provided at the output end of the solenoid valve 206. With this technical solution, the metering pressure storage tank 205 can store high-pressure gas, and the pressure can be released by opening the solenoid valve 206 when needed.

[0025] Furthermore, a one-way valve 208 is provided at the end of the connecting pipe 3 207, and a pressure sensor 209 is provided on the rear surface of the one-way valve 208. The one-way valve 208 is connected to the outer surface of the suction pipe 103. With this technical solution, the pressure sensor 209 can be used to replenish the pressure in time by using the pressure inside the metering pressure tank 205 when it is necessary to clean the vane pump 102 or when the pressure generated by the vane pump 102 is insufficient, so as to ensure the normal use of the equipment.

[0026] like Figures 3-4 As shown, the filter assembly 200 includes a connecting pipe 3 on the upper surface of the separation box 202, and the outer surface of the end of the connecting pipe 3 is provided with a threaded groove 301. The outer surface of the rear end of the connecting pipe 3 is provided with a sealing positioning ring 302, and a connecting pipe 304 is slidably installed on the outer surface of the sealing positioning ring 302. The end of the connecting pipe 304 is connected to the outer surface of the metering pressure tank 205. In this technical solution, the sealing positioning ring 302 can assist the connecting pipe 3 and the connecting pipe 304 in positioning and installation.

[0027] Furthermore, a connecting sleeve 303 is spirally installed on the outer surface of the front end of the connecting pipe 5 304, and the connecting pipe 5 304 and the connecting pipe 4 3 are fixedly connected by the connecting sleeve 303. With this technical solution, the sealing shell 305 with multi-layer filter rings 306 can be quickly removed for cleaning and maintenance through the setting of the connecting sleeve 303.

[0028] Furthermore, a sealing shell 305 is provided at the connection of the connecting pipe 304, and multiple multi-layer filter rings 306 are provided on the inner surface of the sealing shell 305. This technical solution, through the setting of multi-layer filter rings 306, can further filter the lead and impurities in the separated high-pressure gas multiple times to ensure the cleanliness of the high-pressure gas.

[0029] Working Principle: When using this lead pump for lead-acid battery production, firstly, upon system startup, the servo motor 1 drives the transmission rod 101 to rotate, thereby driving the vane pump 102 to work. The suction force generated by the vane pump draws in molten lead through the suction pipe 103 and delivers it to the mold via the discharge pipe 104. When the pressure in the suction pipe 103 exceeds the set value of the pressure relief valve 2, the pressure relief valve automatically opens, and the excess molten lead enters the separation tank 202 through the connecting pipe 1 201 for gas-liquid separation. The separated molten lead flows back to the suction pipe 103 for recycling through the connecting pipe 2 203, while the separated gas is deeply purified through multi-layer filter rings 306 and then stored in the metering pressure storage tank 205.

[0030] When cleaning of the vane pump 102 or pressure compensation of the suction pipe 103 is required, the pressure sensor 209 monitors the pressure change in real time and triggers the solenoid valve 206 to open. At this time, the high-pressure gas in the metering storage tank 205 is injected into the suction pipe 103 through the connecting pipe 207 to achieve the pressure replenishment function. This is the working principle of the lead pump used in lead-acid battery production.
