Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery production technology, specifically to a lead powder collection device for production. Background Technology

[0002] A lead powder machine is a specialized piece of equipment used to produce lead powder, an important chemical raw material widely used in industries such as batteries, coatings, rubber, plastics, and printing and dyeing. The machine melts lead blocks and processes them into lead powder using a special process. However, the lead powder produced by the machine needs to be collected in a powder collection box. Existing collection boxes have poor filtration efficiency, and the gas expelled after passing through the collection box often carries a small amount of lead powder, easily causing air pollution. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical problem solved by this utility model is to provide a lead powder collection device that solves the problem of poor lead powder collection and filtration effect in existing devices.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a lead powder collection device, including a powder collection box, a screw conveyor, a bag filter, a pulse dust collector, a high-efficiency filter, and a negative pressure fan. The powder collection box is installed on a base frame and consists of a lower box, a middle box, and an upper box from bottom to top. The lower box has an air inlet connected to the output pipe of the lead powder machine to guide the lead powder-containing airflow into the powder collection box. The bottom of the powder collection box is equipped with a screw conveyor, and the output port of the screw conveyor is connected to a powder storage bin. The middle box is equipped with a bag filter and a pulse dust collector, and the bag filter contains filter bags. The upper box is equipped with a pneumatic valve. The base frame is equipped with a high-efficiency filter and a negative pressure fan. The upper box and the high-efficiency filter are connected by a pipe, and the negative pressure fan is located behind the high-efficiency filter.

[0005] The beneficial effects of this solution are as follows: Compared with the existing technology, the lead powder collection device of this utility model performs secondary filtration of the lead powder-containing airflow by setting a bag filter and a high-efficiency filter, which greatly improves the filtration effect. Combined with the action of a pulse dust collector and a negative pressure fan, it improves the collection efficiency of lead powder, so that the lead powder-containing airflow meets the emission standards after passing through the collection device, and has minimal impact on the air environment.

[0006] Furthermore, the dust collection box is installed on a flat surface with a bearing capacity greater than or equal to 1.1 kg / m². 2 Each box is sealed together, with sealing rubber strips and sealant applied to the mating surfaces. After the boxes are connected and installed, sealant is applied to the mating surfaces to fill the gaps, ensuring the stable operation of the entire collection device.

[0007] Furthermore, the bag filter also includes an installation plate. The filter bag is installed by insertion. During installation, the filter bag is vertically inserted into the hole of the installation plate, and the elastic hoop is embedded in the hole to press the filter bag tightly, thus keeping the filter bag installed stably.

[0008] Furthermore, the pulse dust collector can set the vibration interval time according to the airflow pressure difference before and after filtration by the bag filter to ensure the filtration efficiency of the bag filter.

[0009] Furthermore, a star-shaped powder discharge valve is provided at the output port of the screw conveyor to facilitate control of the lead powder flow rate, thereby ensuring smooth airflow and improving efficiency.

[0010] Furthermore, the high-efficiency filter can capture lead powder particles larger than 0.5 μm. The lead powder used to make lead-acid battery plates has a particle size of about 25 μm, ensuring that the lead powder in the lead-powder-containing airflow can be filtered out and collected, and the discharged airflow meets emission standards and will not cause damage to the air environment.

[0011] Furthermore, the base frame is equipped with a chimney pipe at the outlet of the high-efficiency filter. The outlet of the chimney pipe is higher than the roof surface, which can discharge the gas to a height above the roof. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] Implementation, for example, attached Figs. 1-2The diagram shows a lead powder collection device, comprising a collection box, a screw conveyor 1, a bag filter 2, a pulse dust collector 3, a high-efficiency filter 4, and a negative pressure fan 5. The collection box is mounted on a base frame 6 and consists of a lower box 7, a middle box 8, and an upper box 9 from bottom to top. The lower box 7 has an air inlet 10 connected to the output pipe of the lead powder generator, which guides the lead powder-containing airflow into the collection box. The bottom of the collection box is equipped with the screw conveyor 1, whose output port is connected to a powder storage bin. When the lead powder-containing airflow enters the collection box, some of the lead powder sinks to the bottom due to gravity and is then conveyed to the powder storage bin by the screw conveyor 1. The middle box 8 is equipped with the bag filter 2 and the pulse dust collector 3. Some of the lead powder-containing airflow rises from the lower box 7 due to the negative pressure of the fan. The airflow passes through the middle chamber 8 and is filtered by the bag filter 2. The bag filter 2 contains filter bags, which trap most of the lead powder in the airflow. The pulse vibration of the pulse dust collector 3 causes the lead powder on the filter bags to fall into the screw conveyor 1 at the bottom of the lower chamber 7. The upper chamber 9 is equipped with a pneumatic valve 11, and the base frame 6 is equipped with a high-efficiency filter and a negative pressure fan 5. The upper chamber 9 and the high-efficiency filter are connected by a pipe 12. The airflow entering the upper chamber 9 passes through the pneumatic valve 11 and enters the pipe 12 before entering the high-efficiency filter for secondary filtration. The negative pressure fan 5 is located behind the high-efficiency filter, so that the airflow enters the high-efficiency filter under the action of the negative pressure fan 5. The high-efficiency filter filters out the small amount of lead powder in the airflow and discharges clean gas that meets the emission standards.

[0017] The dust collection box is installed on a level ground with a ground bearing capacity greater than or equal to 1.1 kg / m². 2 The various housings are sealed together, with sealing rubber strips and sealant applied to the mating surfaces. After installation, sealant is applied to the mating surfaces to fill any gaps, ensuring stable operation of the entire collection device. The bag filter 2 also includes a mounting plate. The filter bags are installed using an insert method; during installation, the filter bags are vertically inserted into the holes of the mounting plate, and elastic clamps are inserted into the holes to press the filter bags tightly, ensuring stable installation. The pulse dust collector 3 can set the vibration interval time according to the airflow pressure difference before and after filtration by the bag filter 2 to ensure the filtration efficiency of the bag filter 2. The screw... A star-shaped powder discharge valve 13 is provided at the output port of the rotary conveyor 1 to facilitate the control of lead powder flow, so as to make the airflow smooth and thus improve efficiency; the high-efficiency filter can capture lead powder particles larger than 0.5um. The lead powder used to make lead-acid battery plates has a particle size of about 25um, which ensures that the lead powder in the lead powder airflow can be filtered out and collected, and the discharged airflow meets the emission standards and will not cause damage to the air environment; a chimney pipe 14 is provided on the base frame 6 at the outlet of the high-efficiency filter. The outlet of the chimney pipe 14 is higher than the roof surface, so that the gas can be discharged to a height above the roof.

[0018] The specific implementation process is as follows:

[0019] The lead-powder-containing airflow enters the dust collection box through the air inlet 10 of the lower box 7. Some of the lead powder sinks to the bottom of the box due to gravity and is then transported to the dust storage silo by the screw conveyor 1. Some of the lead-powder-containing airflow rises from the lower box 7 to the middle box 8 due to the negative pressure of the fan. It is filtered by the bag filter 2, which traps most of the lead powder in the airflow on the filter bag. The pulse vibration of the pulse dust collector 3 causes the lead powder on the filter bag to fall into the screw conveyor 1 at the bottom of the lower box 7. The airflow continues to pass through the pipe 12 and enters the high-efficiency filter from the upper box 9. The negative pressure fan 5 works with the high-efficiency filter to filter and collect the lead powder, ensuring that the gas discharged from the collection device is clean and meets the exhaust requirements. The filtration effect is good and the efficiency is high.
