Technical Field

[0001] This utility model relates to the field of grain processing equipment technology, and in particular to a high-pressure bottomless pulse dust collector for rice processing. Background Technology

[0002] With rapid economic development and improved living standards, the demand for rice, one of my country's staple foods, has been increasing year by year, leading to the rapid development of the rice processing industry. However, rice processing, such as milling and polishing, generates a large amount of dust. This dust not only poses a serious threat to the health of workers but may also cause safety accidents such as explosions, while also polluting the surrounding environment. To address the dust pollution problem, rice processing enterprises generally use dust removal equipment to collect and treat the dust.

[0003] However, existing dust collectors suffer from low dust removal efficiency and high energy consumption, which greatly limits their effectiveness in practical applications.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-pressure bottomless pulse dust collector for rice processing, aiming to improve the problems of low dust removal efficiency and high energy consumption in existing dust collectors, which greatly limits the effectiveness of dust collectors in practical applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure bottomless pulse dust collector for rice processing, comprising a dust collection box, wherein a perforated fixing plate is provided inside the dust collection box, and a filter assembly is provided in the middle of the perforated fixing plate;

[0007] The filtration assembly includes multiple filter cartridges, all of which are fixedly connected to the middle of a porous fixing plate. A venturi tube is connected to the top of each filter cartridge, and a high-speed nozzle is fixedly connected to the top of each venturi tube. A support plate is fixedly connected to the upper left side of the dust collector, and a fixed platform is fixedly connected to the top of the support plate. A compressed air storage tank is installed at the top of the fixed platform, and a solenoid valve is fixedly connected to the top of the middle section of the compressed air storage tank. The output end of the solenoid valve is connected to a blowpipe. A pulse valve is fixedly connected to the top of each of the high-speed nozzles through the blowpipe. A pretreatment assembly is installed at the lower left side of the dust collector.

[0008] As a further description of the above technical solution:

[0009] The pretreatment component includes a dust-laden gas inlet pipe, which is fixedly connected to the lower left side of the dust collector. A filter plate is installed inside the dust-laden gas inlet pipe. Multiple evenly distributed limiting grooves are opened on the left side of the inner wall of the dust-laden gas inlet pipe. Multiple evenly distributed limiting blocks are fixedly connected to the outer wall of the filter plate.

[0010] As a further description of the above technical solution:

[0011] The plurality of the limiting blocks are slidably connected to the inner sidewall of the limiting groove.

[0012] As a further description of the above technical solution:

[0013] A clean gas exhaust pipe is fixedly connected to the right side of the dust collector, and a pulse frequency controller is fixedly connected to the left side of the dust collector.

[0014] As a further description of the above technical solution:

[0015] A top cover is fixedly connected to the top of the dust collector, and a base is fixedly connected to the bottom of the outer side wall of the dust collector.

[0016] As a further description of the above technical solution:

[0017] The bottom of the dust collector is fixedly connected to a dust hopper, and the bottom of the dust hopper is fixedly connected to a connecting flange.

[0018] As a further description of the above technical solution:

[0019] A ash storage box is fixedly connected to the bottom end of the connecting flange. Two locking wheels are fixedly connected to the front side of the bottom end of the ash storage box, and two omnidirectional wheels are fixedly connected to the rear side of the bottom end of the ash storage box.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, multiple filter cartridges are evenly fixed inside the dust collection box by a perforated fixing plate. At the same time, a pulse valve is installed in the middle of a high-speed nozzle fixed at the top of the filter cartridge for periodic jet cleaning of the filter cartridge. The pulse valve works in conjunction with a solenoid valve installed on the jet pipe to adjust the jet pressure and jet frequency to meet the cleaning needs under different dust loads, thereby improving the cleaning effect, reducing the replacement frequency of the filter cartridge, and thus effectively collecting and treating the dust generated during rice processing, improving dust removal efficiency, and reducing the energy consumption required by the equipment.

[0022] 2. In this utility model, by opening a limiting groove on the inner side wall of the dust-laden gas inlet pipe and installing a limiting block on the outer side wall of the filter plate, the filter plate can be installed inside the dust-laden gas inlet pipe, thereby pre-treating the dust-laden gas entering the dust collector. This not only reduces the filtration pressure of the filter cartridge but also effectively improves the filtration effect of the filter cartridge on the gas. At the same time, the filter plate is easy to disassemble, making it convenient to remove and clean the surface dust after the operation is completed. Attached Figure Description

[0032] Specifically: The solenoid valve (9) is an energy-saving solenoid valve, which can be used to precisely control the injection time and interval of pulse jet, while realizing energy saving and consumption reduction.

[0033] Reference Figure 2 and Figure 3 The pretreatment component includes a dust-laden gas inlet pipe (12), which is fixedly connected to the lower left side of the dust collector (1). A filter plate (13) is installed inside the dust-laden gas inlet pipe (12).

All of the limiting blocks (15) are slidably connected to the inner wall of the limiting grooves (14).

[0034] Specifically: The limiting block (15) fixed on the outer side wall of the filter plate (13) is slidably connected to the inner side wall of the limiting groove (14), so that the filter plate (13) can be removed and the surface dust cleaned after the operation is completed.

[0035] Reference Figure 1 and Figure 4The bottom end of the dust collector (1) is fixedly connected to a dust hopper (20), and the bottom end of the dust hopper (20) is fixedly connected to a connecting flange (21); the bottom end of the connecting flange (21) is fixedly connected to a dust storage box (22), and the front side of the bottom end of the dust storage box (22) is fixedly connected to two locking wheels (23), and the rear side of the bottom end of the dust storage box (22) is fixedly connected to two universal wheels (24).

At the same time, a pulse valve 11 is installed in the middle of the high-speed nozzle 5 fixed at the top of the filter cartridge 3 for periodic blowing and cleaning of the filter cartridge 3. The pulse valve 13 cooperates with the solenoid valve 9 installed on the blow pipe 10 to adjust the blowing pressure and blowing frequency to adapt to the cleaning needs under different dust loads, improve the cleaning effect, reduce the replacement frequency of the filter cartridge 3, and thus effectively collect and treat the dust generated during rice processing, improve the dust removal efficiency, and reduce the energy consumption required by the equipment. At the same time, a dust storage box (22) is connected to the bottom of the connecting flange (21) fixed at the bottom of the ash hopper (20), which can conveniently collect and centrally process the dust, and at the same time prevent dust particles from being suspended in the air and inhaled by the workers, resulting in respiratory diseases and other health problems.
