Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery recycling technology, specifically relating to a dust removal and purification device for lead-acid battery recycling. Background Technology

[0002] Lead-acid batteries mainly consist of positive and negative plates, separators, electrolyte, and a casing. The positive plate is usually made of lead dioxide, the negative plate is made of spongy lead, and the electrolyte is a sulfuric acid solution. During charging, electrical energy causes a chemical reaction inside the battery, converting electrical energy into chemical energy for storage; during discharging, the chemical energy is converted back into electrical energy and output to power various devices.

[0003] During the recycling of waste lead-acid batteries, especially during the crushing and screening of waste batteries, a large amount of battery powder dust and toxic gases are generated. The dust contains a large amount of toxic heavy metals such as lead and chromium, and the gas contains harmful gases such as hydrogen sulfide and sulfur dioxide.

[0004] Therefore, in the lead-acid battery recycling process, the gas generated during the recycling process is extracted and drawn into a filtration mechanism. After filtration of toxic components, the gas is passed into a purification cylinder filled with clean water. The clean water filters and settles the dust in the gas. However, when the gas is directly passed into the clean water, large bubbles are generated. This prevents the gas inside the bubbles from contacting the clean water, resulting in poor filtration of the gas by the clean water. Therefore, it is necessary to design a dust removal and purification device that can break up large bubbles, reduce their volume, and improve the contact effect between the gas and the clean water. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal and purification device for lead-acid battery recycling, which solves the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust removal and purification device for lead-acid battery recycling, comprising a purification cylinder, an exhaust pipe on the upper side of the purification cylinder, a feed pipe on the lower side of the purification cylinder, a one-way valve mounted on the feed pipe, a connecting pipe connected to the lower side of the feed pipe, a filter mechanism at the other end of the connecting pipe, a rotating shaft rotatably mounted inside the purification cylinder, a drive mechanism connected to the rotating shaft on the upper side of the purification cylinder, a plurality of material distribution mechanisms extending from top to bottom on the portion of the rotating shaft extending into the purification cylinder, each material distribution mechanism including an annular component connected to the outer surface of the rotating shaft, a plurality of dispersing rods on the outer surface of the annular component, a mounting ring connected to the outer surfaces of the plurality of dispersing rods, partitions on both the upper and lower sides of the plurality of dispersing rods, a plurality of vent holes on each of the two partitions, the rotating shaft rotatably connected to the center of the two partitions, and both partitions connected to the inner wall of the purification cylinder.

[0007] The upper side of the purification cylinder is connected to a water inlet pipe, which is equipped with a first solenoid valve and is connected to an external water supply. The lower side of the purification cylinder is provided with a water outlet pipe, one end of which extends into the purification cylinder, bends downward, and points towards the center of the lower inner wall of the purification cylinder. The water outlet pipe is equipped with a second solenoid valve, and one end of which is connected to an external suction mechanism.

[0008] The water outlet pipe extends into the inner wall of the purification cylinder and is provided with a retaining ring. The retaining ring has a through hole in the center and a sealing plate on the upper side of the retaining ring. The sealing plate can seal the through hole and has a spring-loaded component on the upper side of the sealing plate.

[0009] The rebound assembly includes a telescopic rod disposed on the upper side of the sealing plate, a spring sleeved on the outer surface of the telescopic rod, and a bracket connected to the inner wall of the water outlet pipe on the upper side of the telescopic rod.

[0010] The drive mechanism includes a motor located at the upper end of the purification cylinder, and the motor is connected to the rotating shaft for transmission.

[0011] The filtration mechanism includes a filter cylinder, the connecting pipe is connected to the lower end of the filter cylinder, the filter cylinder is provided with a filter element, and the upper outer wall of the filter cylinder is provided with an air inlet pipe.

[0012] The purification cylinder is equipped with an inspection door.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. After the gas is initially filtered by the filtration mechanism, it is injected into the purification cylinder. Clean water is used to further precipitate and filter the gas, improving the purification effect. The high-speed rotation of the shaft drives the distribution mechanism to start working. The distribution mechanism can break up the bubbles generated after the gas comes into contact with the clean water, reducing the volume of the bubbles. This improves the contact effect between the gas and the clean water, thus improving the filtration effect of the gas.

[0015] 2. The filter water inside the purification cylinder can be replaced by the combination of the inlet and outlet pipes. The design of one end of the outlet pipe pointing to the lower inner wall of the purification cylinder allows the dust deposited on the lower inner wall of the purification cylinder to be extracted during the water discharge process, which can effectively clean the inside of the purification cylinder.

[0016] 3. The sealing plate seals the through hole under the expansion of the rebound component. When water is drawn from the purification cylinder, it can overcome the elasticity of the rebound component and drive the sealing plate upward to cancel the seal on the through hole, which will not affect the water pumping.

[0017] 4. The motor design can effectively drive the rotating shaft to rotate at high speed, thereby driving the material distribution mechanism to effectively break up the air bubbles. Attached Figure Description

[0028] like Figure 1-4 As shown, this utility model discloses a dust removal and purification device for lead-acid battery recycling, including a purification cylinder 1. An exhaust pipe 101 is provided on the upper side of the purification cylinder 1, and a feed pipe 11 is provided on the lower side of the purification cylinder 1. A one-way valve 12 is installed on the feed pipe 11, and a connecting pipe 13 is connected to the lower side of the feed pipe 11. A filter mechanism is provided at the other end of the connecting pipe 13. A rotating shaft 14 is rotatably mounted inside the purification cylinder 1. A drive mechanism connected to the rotating shaft 14 is provided on the upper side of the purification cylinder 1. The portion of the rotating shaft 14 extending into the purification cylinder 1 has several material distribution mechanisms arranged from top to bottom. Each material distribution mechanism includes an annular component 2 connected to the outer surface of the rotating shaft 14. Several dispersing rods 21 are provided on the outer surface of the annular component 2. A mounting ring 22 is connected to the outer surface of the several dispersing rods 21. Partitions 23 are provided on both the upper and lower sides of the several dispersing rods 21. Several vent holes 24 are provided on each of the two partitions 23. The rotating shaft 14 is rotatably connected to the center of the two partitions 23, and both partitions 23 are connected to the inner wall of the purification cylinder 1.

[0029] In the recycling of lead-acid batteries, the lead-acid batteries are damaged, and the gas generated during the recycling process is extracted by a ventilation mechanism and drawn into a filtration mechanism. The gas is initially filtered by the filtration mechanism to remove toxic components and dust. The gas that has passed through the filtration mechanism is injected into the feed pipe 11 through the connecting pipe 13. Then, the gas is injected into the purification cylinder 1 from the bottom through the feed pipe 11. Since the purification cylinder 1 is filled with clean water, the gas can fully contact the clean water. The clean water further precipitates and filters the dust in the gas.

[0030] During the process of gas entering the purification cylinder 1, the drive mechanism starts working, which drives the rotating shaft 14 to rotate at high speed inside the purification cylinder 1. The rotating shaft 14 then drives several distributing mechanisms to start working. Since the annular part 2 is located on the outer surface of the rotating shaft 14, the annular part 2 rotates at high speed along with the rotating shaft 14. The annular part 2 drives several dispersing rods 21 to rotate at high speed. After the gas enters the purification cylinder 1 from the bottom, the gas passes through each distributing mechanism. When the gas passes through the distributing mechanism, it first passes through the lower partition 23 and enters the space between the two partitions 23 through the vent holes 24 of the lower partition 23. Since the vent holes 24 of the lower partition 23 disperse the gas, the several vent holes 24 on the lower side can disperse the gas and the purification cylinder. The bubbles generated by contact with water are dispersed, reducing their volume and breaking large bubbles into smaller ones. The bubbles after the first separation are located between two partitions 23. Due to the high-speed rotation of several dispersing rods 21 between the two partitions 23, the dispersing rods 21 can further disperse the bubbles, reducing their volume and improving the contact efficiency between the gas and water. This enhances the purification and sedimentation effect of the water on the dust in the gas. After being dispersed by the dispersing rods 21, the bubbles pass through the vent holes 24 of the upper partition 23 again. This design can further effectively disperse the bubbles and improve the purification effect of the bubbles and water. Finally, the gas is discharged outward through the exhaust pipe 101.

[0031] The upper side of the purification cylinder 1 is connected to a water inlet pipe 3, which is equipped with a first solenoid valve 31 and is connected to an external water supply. The lower side of the purification cylinder 1 is provided with a water outlet pipe 32, one end of which extends into the purification cylinder 1, bends downward, and points to the center of the lower inner wall of the purification cylinder 1. The water outlet pipe 32 is equipped with a second solenoid valve 33 and one end of which is connected to an external suction mechanism.

[0032] When it is necessary to inject clean water into the purification cylinder 1, clean water can be added to the purification cylinder 1 through the water inlet pipe 3. When it is necessary to discharge the water in the purification cylinder 1, the external suction mechanism is activated to generate negative pressure at the water outlet pipe 32, and the clean water in the purification cylinder 1 is drawn out through the water outlet pipe 32. Since one end of the water outlet pipe 32 extends into the purification cylinder 1 and bends downward, pointing towards the center of the lower inner wall of the purification cylinder 1, the dust deposited on the lower inner wall of the purification cylinder 1 can be extracted, thereby improving the cleaning effect inside the purification cylinder 1.

[0033] The water outlet pipe 32 extends into the inner wall of the purification cylinder 1 and is provided with a retaining ring 34. The retaining ring 34 has a through hole 35 in the center and a sealing plate 36 on the upper side of the retaining ring 34. The sealing plate 36 can seal the through hole 35 and a rebound component is provided on the upper side of the sealing plate 36.

[0034] Under the stretching action of the rebound assembly, the sealing plate 36 keeps the through hole 35 closed, thus sealing the end of the water outlet pipe 32 that enters the purification cylinder 1, preventing impurities and gas from entering the water outlet pipe 32 during the gas purification process. After the external suction mechanism is activated, the water outlet pipe 32 generates suction, which drives the sealing plate 36 to move upward, releasing the seal on the through hole 35. This causes the rebound assembly to start compressing. After the sealing plate 36 releases the seal on the through hole 35, the clean water in the purification cylinder 1 can be drawn out of the purification cylinder 1 through the water outlet pipe 32. When the water pumping is stopped, under the stretching action of the rebound assembly, the sealing plate 36 is moved back to its original position, sealing the through hole 35 again.

[0035] The rebound assembly includes a telescopic rod 4 located on the upper side of the sealing plate 36, a spring 41 sleeved on the outer surface of the telescopic rod 4, and a bracket 42 connected to the inner wall of the water outlet pipe 32 on the upper side of the telescopic rod 4.

[0036] The bracket 42 supports the telescopic rod 4. Under the action of the spring 41, the sealing plate 36 moves downward to close the through hole 35. When drawing clean water, the sealing plate 36 moves upward and the spring 41 begins to compress.

[0037] The drive mechanism includes a motor 43 located at the upper end of the purification cylinder 1, and the motor 43 is connected to the rotating shaft 14 for transmission. When the motor 43 starts working, it can drive the rotating shaft 14 to rotate at high speed.

[0038] The filtration mechanism includes a filter cylinder 44, a connecting pipe 13 connected to the lower end of the filter cylinder 44, a filter element inside the filter cylinder 44, and an air inlet pipe 46 on the upper outer wall of the filter cylinder 44. Gas is injected into the filter cylinder 44 through the air inlet pipe 46, and the gas is initially filtered by the filter element. After filtration, the gas is injected into the purification cylinder 1 through the connecting pipe 13.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
