DETAILED DESCRIPTION

[0018] The patent will be further described below in conjunction with specific embodiments, which should be understood as merely illustrating the patent and not limiting the scope of the patent. In addition, it should be understood that those skilled in the art can make various modifications or changes to the patent after reading the content taught by the patent, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0019] Reference Figure 1 , Figure 2 and Figure 3 is the schematic diagram of the structure of the patent, a lead-acid battery wastewater filtering device, comprising a box 1 and a filter screen 9, the inner side wall of the box 1 is integrally formed with a partition 2, the middle part of the partition 2 is embedded with a drain pipe 3, the drain pipe 3 is provided with a solenoid valve, the bottom of the drain pipe 3 is fixedly installed with a shunt pipe 4, the top of the box 1 is fixedly installed with a motor 5, the rotating shaft of the motor 5 is fixedly installed with a stirring rod 6, the lower side of the right side wall of the box 1 is provided with a mounting hole 7, the inner side wall of the mounting hole 7 is fixedly installed with a fixing ring 8 on the left side, the right side surface of the fixing ring 8 is installed with a sealing ring, the right end of the filter screen 9 is installed with a mounting plate 10, the four corners of the mounting plate 10 are provided with circular holes, the circular holes are provided with bolts 11, the left end of the bolts 11 is screwed into the threaded groove on the right side of the box 1, the left side surface of the mounting plate 10 is tightly attached to the sealing ring;

[0020] As Figure 1 shown, the shunt pipe 4 is multiple and divided into multiple directions, which facilitates the discharge of wastewater and flocculent sediment in the drain pipe 3 to different positions of the filter screen 9.

[0021] Two fixing plates 12 are fixedly installed on the right side of the housing 1. The inner sides of the two fixing plates 12 are provided with wheel grooves 13. One end of an L-shaped rod 14 is fixedly installed on the upper and lower sides of the right side of the mounting plate 10. The other end of the L-shaped rod 14 is mounted with a support wheel 15 through a wheel seat. The support wheel 15 is rolled in the wheel groove 13.

[0022] Specifically, the left and right ends of the wheel groove 13 are open.

[0023] With the left and right ends of the wheel groove 13 in an open state, it is convenient to install the support wheel 15 in the wheel groove 13 at the end of the wheel groove 13.

[0024] Specifically, the mounting plate 10 is provided with a through hole 16, and a screw 17 is fixedly installed on the right end of the filter screen 9. The right end of the screw 17 passes through the through hole 16 and is screwed with a nut 18. A rubber ring 19 is fitted on the left side of the nut 18, and the left side of the rubber ring 19 is tightly fitted to the right side of the mounting plate 10.

[0025] The screw 17 and nut 18 facilitate the disassembly of the filter screen 9 and the mounting plate 10, making it easy to remove the filter screen 9 separately for cleaning.

[0026] Specifically, the inner wall of the circular hole is provided with an annular groove 20, and an annular ring 21 is integrally formed on the side wall of the bolt 11, with the annular ring 21 located inside the annular groove 20.

[0027] By setting the ring 21 inside the ring groove 20, the effect of the bolt 11 and the mounting plate 10 as a whole is enhanced. When the mounting plate 10 and the housing 1 are disassembled, the bolt 11 can be prevented from coming out of the round hole on the mounting plate 10 and causing the parts to be lost.

[0028] Specifically, the sidewall of bolt 11 does not contact the inner sidewall of the circular hole, and the outer sidewall of ring 21 is slidably mounted on the inner sidewall of ring groove 20.

[0029] By ensuring that the sidewall of bolt 11 does not contact the inner wall of the circular hole, wear caused by the thread on bolt 11 contacting the inner wall of the circular hole can be avoided. By allowing the outer wall of the ring 21 to slide on the inner wall of the ring groove 20, bolt 11 can be prevented from shaking in the circular hole, so that bolt 11 can only move left and right in the circular hole.

[0030] Specifically, the mounting plate 10 includes a left plate body 22 and a right plate body 23.

[0031] By dividing the mounting plate 10 into a left plate 22 and a right plate 23, it is possible to... Figure 2The annular groove 20 is divided into two parts from the middle position, which facilitates the opening of the annular groove 20 in the early stage and also facilitates the installation of the ring 21 in the annular groove 20. After the installation is completed, the opposite sides of the left plate 22 and the right plate 23 can be fixed together by spot welding at the edge.

[0032] Working principle: Lead-acid battery wastewater is injected into the tank 1 through the water inlet pipe on the upper left side of the tank 1. A precipitating agent is added through the injection pipe on the right side of the top of the tank 1. At the same time, the wastewater and the precipitating agent react fully when the stirring rod 6 is rotated by the motor 5. Metal ions such as lead and cadmium in the wastewater form flocculent precipitates. After the reaction is completed, the solenoid valve in the drain pipe 3 is opened to discharge the wastewater and flocculent precipitates. The flocculent precipitates and sewage can be diverted to different positions of the filter screen 9 through the diversion pipe 4, which improves the utilization rate of the filter screen 9 and avoids clogging of individual positions of the filter screen 9, thereby improving the water filtration effect. The flocculent precipitates are intercepted by the filter screen 9, and the wastewater falls to the bottom of the tank 1. When cleaning the flocculent precipitates, the bolt 11 and the threaded groove on the right side of the outside of the tank 1 are removed. The mounting plate 10 is moved to the right until the filter screen 9 is detached from the tank 1. Then the filter screen 9 can be removed from the mounting plate 10 for cleaning.

[0033] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0034] This patent features multiple diversion pipes at different angles fixedly installed at the bottom of the sewage pipe. These diversion pipes can distribute flocculent sediment and sewage to different positions on the filter screen, improving the utilization rate of the filter screen and preventing blockage in individual positions, thus enhancing the water filtration effect. The right side of the mounting plate is connected to support wheels on both the top and bottom sides by L-shaped rods. The support wheels are rolled and installed in the wheel grooves of the fixed plate. When disassembling the mounting plate, the support wheels move and support the mounting plate, eliminating the need for manual lifting, making operation convenient and reducing labor intensity.
