Description

Technical Field

[0001] This invention relates to the field of electrostatic precipitator chamber pumps, specifically an exhaust filtration device for an electrostatic precipitator chamber pump. Background Technology

[0002] An electrostatic precipitator dust silo pump is a device that uses compressed air to concentrate the dust collected by the electrostatic precipitator through a sealed pressure vessel, and then efficiently and environmentally transports it to a designated ash silo via pneumatic conveying in a pipeline.

[0003] An existing electrostatic precipitator (ESP) silo pump exhaust filtration device can be found in application number CN202311529496.7, which describes an ESP silo pump ash conveying system. This system includes a silo pump, a main pipeline, a first conveying pipeline, and a second conveying pipeline. The first and second conveying pipelines are intersected and both connect to the main pipeline. A first probe is installed in the first conveying pipeline to detect the degree of ash accumulation, and a second probe is installed in the second conveying pipeline to detect the degree of ash accumulation. The main pipeline has an internal gear ring and a rotating gear ring meshing with it on its inner wall. The ash conveying system of this invention uses the first and second conveying pipelines to convey ash alternately. When one conveying pipeline becomes clogged, it is sealed and cleaned, while the other conveying pipeline continues to operate normally, avoiding disruption to normal ash conveying efficiency. The first and second probes automatically detect ash blockages, eliminating the need for manual inspection and saving time and effort. The aforementioned device does not have a component for filtering the gas in the exhaust pipe. When the exhaust valve is opened to discharge material, the compressed air inside the silo pump carries the suspended fly ash through the pipe into the upper ash hopper. Since the ash hopper is not a sealed dust collection silo, the dust can easily drift out through the gaps in the flange and inspection port, resulting in excessive dust on site. Therefore, an exhaust filtration device for electrostatic precipitator silo pumps is proposed to address the above problems. Summary of the Invention

[0004] To address the problem that existing devices lack components for filtering the gas in the exhaust pipe, and that when the exhaust valve is opened to discharge material, the compressed air inside the silo pump carries suspended fly ash through the pipe into the upper ash hopper, which is not a sealed dust collection hopper, allowing dust to easily escape through the flanges and inspection port gaps, resulting in excessive dust emissions on site, this invention proposes an exhaust filtration device for electrostatic precipitator silo pumps.

[0015] The advantages of this invention are: 1. This invention achieves efficient filtration and double sealing through the structural design of the filter cleaning and replacement mechanism. The mechanism adopts a multi-layer filter core structure, which can effectively intercept dust particles in the gas. At the same time, the first and second sealing rings set on the inner wall of the moving sleeve are tightly fitted with the fixed pipe, the first exhaust pipe and the second exhaust pipe, respectively, forming a double sealing barrier.

[0016] 2. This invention achieves automatic filter cleaning through the structural design of the filter cleaning and replacement mechanism. When gas passes through the fixed pipe, the airflow drives the fan blade to rotate. The fan blade drives the scraper to rotate synchronously through the transmission rod. During the rotation, the scraper continuously scrapes the bottom surface of the filter element, promptly removing dust particles attached to the surface of the filter element and effectively preventing filter blockage. This automatic cleaning mechanism solves the problem that existing devices are prone to clogging of filter elements after long-term use, requiring frequent replacement and increasing maintenance costs. It significantly reduces the operating and maintenance costs of the equipment and improves the continuous operation stability of the equipment.

[0017] 3. Through the structural design of the filter cleaning and replacement mechanism, this invention enables convenient replacement of the filter element. When replacing the filter element, the entire replacement process does not require the use of special tools, making the operation simple and convenient. This solves the problem of difficult filter element replacement in existing devices, which increases the difficulty of subsequent replacements. It greatly improves the convenience of filter element replacement, shortens equipment maintenance time, and increases equipment utilization. Attached Figure Description

Fixed blocks 30 are also provided on the left and right ends of the outer side of the movable sleeve 12, and the outer side of the movable sleeve 12 is fixedly connected to one end of the fixed block 30. A pressing rod 31 is sleeved inside the other end of the fixed block 30, and the pressing rod 31 is slidably connected to the fixed block 30. The other end of the pressing rod 31 is fixedly connected to the pressing plate 32. Fixed connection; a second return spring 33 is provided inside the fixed block 30.

During operation, gas is transported through the lower main body 1 and the first exhaust pipe 10 to the inside of the fixed pipe 13. It is then filtered by the filter element 14 inside the fixed pipe 13 before being transported to the second exhaust pipe 11, and finally to the upper main body 2. The movable sleeve 12 is also fitted with a first sealing ring 22 on its inner wall at both ends, providing a sealing effect.
