Description

Technical Field

[0001] This patent relates to the field of wastewater treatment technology, specifically a wastewater treatment device for lead-acid batteries. Background Technology

[0002] With the continuous development of industry, the phenomenon of excessive heavy metal content in industrial wastewater is common. Chemical methods are currently the main methods for treating heavy metal-containing wastewater both domestically and internationally. Chelation, also known as the polymeric ion trapping method, refers to the removal and separation of lead and cadmium by adding an appropriate amount of heavy metal trapping agent during wastewater treatment. This process utilizes the principle that the trapping agent combines with metal ions such as lead and cadmium to form corresponding chelates. This reaction can occur at room temperature and within a wide pH range (3-11), and the trapping agent is not affected by coexisting heavy metal ions. Therefore, this method has a high removal rate, excellent flocculation effect, low sludge volume, and easily dewatered sludge.

[0003] Existing lead-acid battery wastewater treatment devices consist of a tank and an internal stirring mechanism. By adding a precipitating agent, metal ions such as lead and cadmium in the wastewater are combined to form flocculent precipitates. However, most existing wastewater treatment devices discharge the flocculent precipitates through an internal spiral conveyor mechanism. After the operation is completed, a large amount of flocculent precipitate adheres to the spiral blades of the spiral conveyor mechanism, which is not convenient for subsequent cleaning. Moreover, the large amount of adhesion will greatly affect the conveying condition of the spiral conveyor mechanism, resulting in reduced work efficiency. Therefore, we propose a lead-acid battery wastewater treatment device. Utility Model Content

The wastewater from the reaction is discharged through a drain pipe, and the flocculent precipitate is trapped by the filter screen, while the water falls to the bottom of the tank. Cleaning the flocculent material is simple; the sealing plate can be removed to take out the filter screen.

[0020] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 4This is a schematic diagram of the structure of this patent. A lead-acid battery wastewater treatment device includes a box 1, a sealing plate 10, and a column 12. A partition 2 is fixedly installed on the inner side wall of the box 1. A drain pipe 3 is embedded in the middle of the partition 2. A solenoid valve is installed in the drain pipe 3. A stirring motor 4 is fixedly installed on the top of the box 1. The bottom end of the rotating shaft of the stirring motor 4 passes through the top of the box 1 and extends into the interior of the box 1. A stirring rod 5 is fixedly installed on the rotating shaft of the stirring motor 4. An installation hole 6 is provided on the right side wall of the box 1. A rectangular ring 7 is fixedly installed on the left side of the inner side wall of the installation hole 6. A sealing ring 8 is installed on the right side of the rectangular ring 7. A filter screen 9 is provided on the lower side of the partition 2. The right end of the filter screen 9 is fixed to the left side of the sealing plate 10. A round hole is provided at each of the four corners of the sealing plate 10. A bolt 11 is installed in the round hole. The left end of the bolt 11 is screwed into the inner side wall of the outer right side of the box 1. The left side of the sealing plate 10 is tightly attached to the right side of the sealing ring 8.

[0022] The bottom end of the column 12 is fixed to the ground. A horizontal rail 13 is fixedly installed on the left side of the column 12. A slip ring 14 is slidably installed on the side wall of the horizontal rail 13. The top end of the slip ring 14 is fixedly installed on the bottom end of the sealing plate 10.

[0023] The sealing plate 10 can be supported from the bottom by sliding the slip ring 14 on the horizontal rail 13. When disassembling, the filter screen 9 can be moved to the outside of the box 1 simply by moving the sealing plate 10 to the right, without the need for personnel to lift it.

[0024] The length of the horizontal rail 13 is sufficient to allow the filter screen 9 to detach from the housing 1.

[0025] Specifically, the slip ring 14 includes a square ring 15, the top of which is fixed to the bottom of the sealing plate 10. The four sides of the inner wall of the square ring 15 are provided with mounting grooves 16. Rollers 17 are connected to the mounting grooves 16 through a rotating shaft. The four sides of the side wall of the horizontal rail 13 are provided with wheel grooves 18. The rollers 17 are rotatably installed in the wheel grooves 18. The inner wall of the square ring 15 does not contact the side wall of the horizontal rail 13.

[0026] If the sliding ring is directly slid on the horizontal rail 13, the sliding friction will be large. However, by rolling the roller 17 in the wheel groove 18, the friction effect can be greatly reduced, making it easier for personnel to operate.

[0027] Specifically, the filter screen 9 is placed at an angle, and a baffle 19 is fixedly installed on the top left end of the filter screen 9.

[0028] By setting the filter screen 9 at an angle, the falling flocculent sediment can be prevented from accumulating in the top center of the filter screen 9, which would affect the downward drainage effect. The baffle 19 can prevent the flocculent sediment from falling to the bottom of the box 1 on the left side.

[0029] Specifically, a square groove 20 is provided on the left side of the sealing plate 10, and a square rod 21 is inserted into the square groove 20. The left end of the square rod 21 is fixed to the right end of the filter screen 9.

[0030] By inserting the square rod 21 into the square groove 20, it is convenient to assemble and disassemble the filter screen 9 relative to the sealing plate 10.

[0031] Specifically, a magnet 22 is fixedly installed inside the square groove 20.

[0032] The square rod 21 is made of iron and can be attracted by the magnet 22, which increases the connection between the filter screen 9 and the sealing plate 10.

[0033] Specifically, the inner wall of the circular hole is provided with an annular groove 23, and an annular ring 24 is integrally formed on the side wall of the bolt 11, with the annular ring 24 located inside the annular groove 23.

[0034] By setting the ring 24 inside the ring groove 23, the effect of the bolt 11 and the sealing plate 10 as a whole is enhanced. When the sealing plate 10 and the housing 1 are disassembled, the bolt 11 can be prevented from coming out of the round hole on the sealing plate 10 and causing the parts to be lost.

[0035] Specifically, the sealing plate 10 includes a first plate 25 and a second plate 26, with one side of the first plate 25 and the second plate 26 being fixed to each other.

[0036] By dividing the sealing plate 10 into a first plate 25 and a second plate 26, it is possible to... Figure 3 The annular groove 23 is divided into two parts from the middle position, which facilitates the opening of the annular groove 23 in the early stage and also facilitates the installation of the annular ring 24 in the annular groove 23. After the installation is completed, the opposite sides of the first plate 25 and the second plate 26 can be fixed together, which can be fixed by spot welding at the edge.

[0037] 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 motor 4 drives the stirring rod 5 to rotate. 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 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 sealing plate 10 is moved to the right until the filter screen 9 is removed from the tank 1. Then the filter screen 9 can be removed from the sealing plate 10 for cleaning.

[0038] 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.

[0039] This patented technology involves installing a sealing plate on the lower right side wall of the chamber using bolts, with a filter screen installed on the left side of the sealing plate. The wastewater from the reaction is discharged through a drain pipe, and the flocculent precipitate is trapped by the filter screen, while the water falls to the bottom of the chamber. Cleaning the flocculent material is simple; the sealing plate can be removed to take out the filter screen. Compared to the traditional screw conveyor mechanism, this makes cleaning easier and more convenient, improves work efficiency, and reduces electricity costs.
