Description

Technical Field

[0001] This utility model belongs to the field of filter cleaning devices, and particularly relates to a filter cleaning device for high-temperature pipelines. Background Technology

[0002] High-temperature piping systems are widely used in various industrial processes, and filters are one of the key components ensuring the normal operation of these systems. They effectively intercept impurities and particulate matter, preventing their accumulation within the pipes, thus ensuring smooth fluid flow and maintaining the stability and safety of the production process.

[0003] However, existing methods for cleaning filters inside high-temperature pipelines have significant drawbacks. Traditional manual cleaning methods require workers to operate regularly in high-temperature environments, which not only presents harsh working conditions but also necessitates frequent cleaning intervals, undoubtedly increasing the workers' workload. Workers must hold brushes and reach into the high-temperature pipelines to scrub the fixed filters, resulting in confined operating space, high difficulty, and low cleaning efficiency.

[0004] Furthermore, even with quick-release designs, the cleaning process for commonly used fixed-installation filters inside pipelines remains cumbersome. After a period of use, the filter must be manually removed from the pipeline and thoroughly scrubbed with a wire brush. The entire process—disassembling, handling, scrubbing, and reinstalling the filter—consumes significant time and labor costs at each stage. Moreover, frequent manual handling can damage the filter, affecting its filtration performance and lifespan. Additionally, manual cleaning cannot guarantee a thorough cleaning each time; residual impurities may quickly recontaminate the filter during subsequent use, reducing filtration efficiency and ultimately impacting the overall operational efficiency of the high-temperature pipeline system. In conclusion, existing methods for cleaning filters inside high-temperature pipelines cannot meet the demands of efficient, safe, and economical industrial production, necessitating an innovative cleaning device to address these issues.

The device is equipped with an installation plate 107, inside which are installed multiple pull rods 105. A guide sheet metal 104 is installed above the pull rods 105.

[0030] In this embodiment, the round brush assembly 2 includes a round brush shaft 21 and a round brush 22. The round brush shaft 21 is mounted above the drive shaft 110, and the round brush 22 is disposed on the outer side of the round brush shaft 21. The drive motor 101 drives the round brush shaft 21 to rotate, thereby driving the round brush to rotate and cleaning the filter screen.

[0031] In this embodiment, the brush assembly 3 includes a brush mounting base 31 and a brush 32. The brush mounting base 31 is mounted on the outside of the mounting plate 107, and the brush 32 is mounted on the bottom of the mounting plate 107 through the brush mounting base 31.

The filter screen conveying assembly 1, the round brush assembly 2, and the plate brush assembly are installed between the hopper 45 and the top cover 45.

[0034] Working principle

[0035] Filter conveying and circulation mechanism

[0036] The screen conveying assembly 10 plays a crucial role in conveying the screen throughout the cleaning process. The drive motor 101, serving as the power source, is mounted on the outside of the motor mounting base 107. When the drive motor 101 starts, its output shaft drives the drive shaft 110 to rotate. The drive shaft 110 is supported and positioned on both sides by the motor mounting base 102 and the drive bearing mounting plate 103, ensuring stable rotation. The rotation of the drive shaft 110, through its connection with the screen, causes the screen to begin moving. Multiple tie rods 105 inside the mounting plate 107 and the guide sheet metal 104 above provide auxiliary support and guidance for the screen, ensuring that the screen does not shift or deform during movement. The belt mounting base 106 is used to install related belts and other components (if any), further assisting in the conveying of the screen. Driven by the drive shaft 110, the screen circulates like a conveyor belt on a flat belt conveyor, continuously conveying the contaminated portion of the screen located inside the pipeline to the cleaning area. Throughout the process, the pipeline does not need to be stopped, maintaining the normal operation of the production system.

[0037] The principle of one-time cleaning with a round brush

[0038] The circular brush assembly 2 is responsible for the initial cleaning of the screen. The circular brush shaft 21 is mounted above the drive shaft 110, forming a specific positional relationship with it in the vertical direction. While the drive motor 101 rotates the drive shaft 110, it transmits power to the circular brush shaft 21 through a specific transmission mechanism (such as a gear set, though not detailed, its existence is inferred), causing the circular brush shaft 21 to rotate accordingly. The circular brush 22 on the outer side of the circular brush shaft 21 rotates at high speed with the shaft's rotation, its bristles making full contact with the dirty screen surface transported from the pipe. Due to the friction between the bristles and the contaminants on the screen, the contaminants are brushed off the screen under the high-speed rotation of the circular brush 22, thus achieving a primary cleaning of the screen. Factors such as the bristle material, length, density, and rotation speed of the circular brush 22 all affect the cleaning effect of this primary cleaning; appropriate parameter settings can ensure the effective removal of larger particles and some loosely attached contaminants from the screen.

[0039] Second cleaning process of scrubbing brush

[0040] After being cleaned once by the round brush 22, the screen continues to move forward under the action of the filter conveying assembly 10, reaching the position of the plate brush assembly 3. The plate brush 32 is mounted on the bottom of the mounting plate 107 via the plate brush mounting base 31, and the waist hole 33 on the plate brush mounting base 31 provides convenience for adjusting the position of the plate brush 32. The operator can adjust the distance between the plate brush 32 and the screen according to the actual situation such as the degree of screen contamination and cleaning effect requirements through the waist hole 33. When the screen passes the plate brush 32, because the screen is in motion, the plate brush 32 and the screen surface generate relative movement, and the friction between the two further removes the contaminants remaining on the screen after the first cleaning. The bristle material, hardness, and arrangement of the plate brush 32 are all designed to adapt to the secondary cleaning needs of different types of contaminants, ensuring that the screen achieves a high cleanliness standard after the second cleaning.

[0041] Pollutant collection process

[0042] During cleaning operations by the round brush 22 and the plate brush 32, the brushed contaminants fall off under gravity. The hopper 45 in the sludge collection box assembly 4 is located below the filter conveying assembly 10, the round brush assembly 2, and the plate brush assembly. Its special shape effectively collects contaminants falling from above and guides them into the sludge collection box 43. The frame 41 provides stable structural support for the entire sludge collection box assembly 4, ensuring the stability of the sludge collection box 43 during contaminant collection. The top cover 42 is installed on top of the hopper 45, preventing external debris from entering the hopper 45 and the sludge collection box 43 and affecting contaminant collection, while also providing some safety protection. A warning light 44 is installed on one side of the hopper 45. When contaminants accumulate to a certain amount in the sludge collection box 43, the warning light 44 will emit a corresponding signal (such as flashing light or sound alert) to remind staff to clean the sludge collection box 43 promptly, ensuring that the sludge collection box 43 has sufficient space to continue collecting contaminants and enabling the cleaning device to operate continuously and normally.

[0043] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
