Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas particulate filtration devices, and more specifically, to a solid particulate filtration structure for exhaust gas treatment. Background Technology

[0002] Used lead-acid batteries are common energy storage devices widely used in automobiles, electric bicycles, backup power supplies, and other fields. However, improper disposal of used lead-acid batteries can lead to serious environmental pollution. Heavy metals such as lead and cadmium remain in the soil and groundwater for a long time, which has a serious impact on the environment and human health. In addition, if the electrolyte in the battery is not properly treated, it will also be directly discharged into the environment, causing pollution to the soil and water. In order to reduce the pollution to the environment, it is usually necessary to recycle used lead-acid batteries.

[0003] The recycling process of waste lead-acid batteries generates a large amount of exhaust gas, which contains harmful gases such as lead vapor, lead dust, and sulfur dioxide, as well as solid particulate matter. If these exhaust gases are not effectively treated, they will pollute the atmospheric environment and affect human health. In order to achieve the effect of pre-filtering solid particulate matter, corresponding solid particulate filter structures are usually used. There are many types of solid particulate filter structures on the market.

[0004] Most solid particulate filter structures utilize filter screens to filter solid particles. However, these screens are fixed to the inner wall of the filter cylinder, and the screen area lacks a corresponding shaking component. This hinders the removal and discharge of solid particles, affecting both unloading and collection. Furthermore, when solid particles clog the filter screen, it reduces its filtration efficiency, causing inconvenience to the user. Therefore, we propose a solid particulate filter structure for exhaust gas treatment. Utility Model Content

[0005] The purpose of this invention is to provide a solid particle filtration structure for exhaust gas treatment, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A discharge valve is fixedly installed on the discharge pipe. An air inlet pipe communicating with the interior of the filter cylinder is fixedly installed on the bottom cylinder body of the filter cylinder. A support ring is fixedly installed on the inner wall of the filter cylinder. A lifting ring is provided above the support ring. Multiple springs arranged in a ring at equal intervals are fixedly installed between the lifting ring and the support ring. A support plate is fixedly installed on the top surface of the lifting ring. A vibration motor is fixedly installed on the support plate. A filter screen is fixedly installed on the inner annular side of the lifting ring. The filter screen is funnel-shaped with a sealed bottom. The air inlet pipe is located below the filter screen.

[0008] Preferably, a side sealing strip is fixedly installed between the top surface of the lifting ring and the inner wall of the filter cylinder, and the number of springs is greater than 6.

[0009] Preferably, a fan is fixedly installed on the wall of the air intake pipe, and a one-way valve is also fixedly installed on the air intake pipe.

[0010] Preferably, a plurality of support legs are fixedly installed at the bottom of the filter cartridge, and a support base is fixedly installed at the bottom end of the support legs.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a filter cylinder with a filter screen inside. Because the filter screen is funnel-shaped with a closed bottom, it can increase the filtration area and perform solid particle filtration. The discharge pipe, unloading valve and vibration motor can promote vibration of the filter screen. After vibration, solid particles are facilitated to fall off and be discharged from the discharge pipe, thus achieving the effect of filtration and treatment of solid particles on the filter screen.

[0017] 2. This utility model, through the water inlet pipe, allows water to enter through the water inlet pipe and spray out from the nozzle, thereby wetting the discharged solid particles and preventing dust from being generated during the discharge process. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0029] Please see Figures 1-5This utility model provides a technical solution: a solid particle filtration structure for exhaust gas treatment, including a filter cylinder 1, a conical hopper 10 fixedly installed at the bottom of the filter cylinder 1, a discharge pipe 11 fixedly installed at the bottom end of the conical hopper 10, a discharge valve 12 fixedly installed on the discharge pipe 11, and the inner wall of the conical hopper 10 is inclined downward at 45° to 60° to discharge the filtered solid particles outward from the discharge pipe 11.

[0030] Specifically, an air inlet pipe 2 that communicates with the inside of the filter cartridge 1 is fixedly installed on the bottom cylinder of the filter cartridge 1. A fan 20 is fixedly installed on the wall of the air inlet pipe 2, and the fan 20 is used for the operation of conveying exhaust gas. A one-way valve 21 is also fixedly installed on the air inlet pipe 2. The one-way valve 21 can ensure the one-way conveying of exhaust gas. When exhaust gas is no longer conveyed in the air inlet pipe 2, the one-way valve 21 can close automatically.

[0031] Specifically, a support ring 17 is fixedly installed on the inner wall of the filter cylinder 1, and a lifting ring 3 is provided above the support ring 17. Multiple springs 33 arranged in a ring shape at equal intervals are fixedly installed between the lifting ring 3 and the support ring 17. The springs 33 can provide support. A support plate 31 is fixedly installed on the top surface of the lifting ring 3. A vibration motor 32 is fixedly installed on the support plate 31. The vibration motor 32 is used to generate vibration. In conjunction with the use of the springs 33, the vibration effect can be improved.

[0032] Specifically, a filter bag 34 is fixedly installed on the inner annular side of the lifting ring 3. The filter bag 34 is funnel-shaped with a sealed bottom. The air inlet pipe 2 is located below the filter bag 34, so that the filter bag 34 can be used for filtration. The vibration generated by the vibration motor 32 can promote the falling of particles in the filter bag 34.

[0033] In this embodiment, a side sealing strip 30 is fixedly installed between the top surface of the lifting ring 3 and the inner wall of the filter cylinder 1, and the number of springs 33 is greater than 6. The side sealing strip 30 can achieve a sealing effect.

[0034] Specifically, multiple support legs 13 are fixedly installed at the bottom of the filter cartridge 1, and a support base 131 is fixedly installed at the bottom end of the support legs 13, so as to realize the support operation by using the support legs 13.

[0035] Furthermore, a transparent window 14 is provided on the body of the filter cartridge 1. The transparent window 14 and the filter cartridge 1 are integrally formed. The transparent window 14 is made of transparent material and is used for observation and operation.

[0036] In addition, a top cover 15 is fixedly installed on the top of the filter cartridge 1, and an exhaust pipe 16 is fixedly installed at the center of the top cover 15. The exhaust pipe 16 is used for the discharge of exhaust gas after particulate filtration.

[0037] It is worth noting that an inlet pipe 4 is fixedly installed on the bottom cylinder of the filter cylinder 1, a valve 40 is fixedly installed on the inlet pipe 4, a water pipe 41 is fixedly installed at the outlet end of the inlet pipe 4, and multiple nozzles 42 are fixedly installed at the bottom of the water pipe 41. The nozzles 42 are located directly below the filter screen 34 to perform spraying operation, ensuring that particulate impurities are discharged along the discharge pipe 11 and are not prone to dust generation.

[0038] When using the solid particle filtration structure for exhaust gas treatment of this utility model, the unloading valve 12 is closed, the air inlet pipe 2 is connected to the external exhaust gas delivery pipeline, and the blower 20 is connected to the external power supply and made to work. When the blower 20 works, the exhaust gas is delivered to the filter cylinder 1. After the exhaust gas passes through the filter screen 34, the solid particles are blocked at the bottom of the filter screen 34, thus achieving the filtration operation of solid particles.

[0039] After filtration, the discharge valve 12 is opened to discharge the solid particles in the conical bucket 10. In addition, the vibration motor 32 is connected to an external power source and made to work. The vibration motor 32 generates vibration, which is transmitted to the filter bag 34, which can promote the solid particles attached to the bottom of the filter bag 34 to fall off and promote the solid particles to be discharged outward along the discharge pipe 11.

[0040] Finally, during the discharge of solid particles, the water inlet pipe 4 can be connected to an external water supply pipeline, and the valve 40 can be opened. As water sprays out from the nozzle 42, it can wet the solid particles, which can reduce the generation of dust.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
