Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment equipment maintenance, and particularly relates to a portable circulating water filter screen cleaning tool. BACKGROUND

[0002] In the circulating water system of a chemical plant, the filter screen as a core filtering component shoulders the important mission of intercepting suspended solids, algae and solid particle impurities in the water body, and plays a crucial role in guaranteeing the water quality of the circulating water, maintaining the efficiency of the heat exchange equipment and ensuring the stable operation of the system. However, in the northern region and the environment with similar climate characteristics, the large-scale drifting phenomenon of willow catkin hairs poses a serious challenge to the performance of the filter screen. The willow catkin hairs are extremely easy to be adsorbed and accumulated on the surface of the filter screen to form a dense covering layer due to their fine and dense fibers, light texture and natural sticky substances attached to the surface. This covering layer not only greatly reduces the water permeability and filtering efficiency of the filter screen, but also causes the pressure difference between the two sides of the filter screen to rise rapidly, thereby increasing the energy consumption of the circulating water pump. In extreme cases, it may even cause serious failures such as insufficient system flow and local blockage, directly threatening the continuous and stable operation of the chemical production device and its safety.

[0003] At present, the traditional filter screen cleaning method widely used in the industry, i.e. manual cleaning, is not only time-consuming and labor-intensive, but also inefficient, and it is often difficult to completely remove the small and strongly adhered willow catkin hairs.

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0023] The embodiment of the present application provides a portable circulating water filter screen cleaning tool, such as Figures 1 to 3The portable circulating water filter screen cleaning tool includes a hot air assembly 1, a brush head assembly 2, a collection box 3 and a connecting pipe 4. The hot air assembly 1 is used to generate high-temperature airflow to soften and peel off the cotton fluff adhered to the filter screen. One end of the connecting pipe 4 is in communication with the output end of the hot air assembly 1, and is used to deliver the high-temperature airflow. The brush head assembly 2 includes a brush rod 22 connected to the other end of the connecting pipe 4 and a brush 23 arranged on the brush rod 22 away from the connecting pipe 4, and the middle part of the brush 23 is provided with a hot air nozzle. The hot air nozzle is used to direct the blowing of the filter screen surface, and the brush 23 is used to physically remove stubborn impurities. The collection box 3 includes a first tank box 31, a second tank box 32 and a plurality of storable supports 33. The second tank box 32 is connected to the first tank box 31 through a sliding structure, and the second tank box 32 and the first tank box 31 jointly constitute a box structure with an open top and one side. The bottom walls of the first tank box 31 and the second tank box 32 are each provided with a plurality of slots 34, and the plurality of supports 33 are hinged in the corresponding slots 34. Among them, the support 33 is completely embedded in the slot 34 in the storage state, and in the unfolded state, the support 33 can be vertically flipped and locked to form a filter screen support platform.

[0024] The filter screen of the present application is made of stainless steel. The brush 23 is made of metal brush wire, which has moderate hardness and can effectively remove impurities on the surface of the filter screen.

[0025] It should be noted that when the filter screen needs to be cleaned, the second tank box 32 is first pulled out of the first tank box 31 and extended to the required length through the sliding guide rail. Then, the support 33 is unfolded to form a horizontal filter screen support platform. The filter screen is placed stably on the platform formed by the plurality of supports 33, at this time, the box structure and the filter screen together form a closed space with only one side open. The brush head assembly 2 extends into the opening from this side to clean the impurities on the filter screen from the outside to the inside. The design of the box structure can effectively collect the impurities washed off by the brush to avoid secondary pollution. Next, the hot air assembly 1 is started to generate a high-temperature airflow. The high-temperature airflow is transported to the hot air nozzle of the brush head assembly 2 through the connecting pipe 4. The operator holds the brush rod 22 and accurately aims the hot air nozzle at the area covered by the poplar fluff on the surface of the filter screen. The effect of the high-temperature airflow softens the sticky substances in the poplar fluff, and the impact force of the airflow preliminarily peels off the loose fluff from the filter screen pores. While continuously blowing hot air, the operator uses the brush 23 to reciprocally brush the surface of the filter screen to further break the stubbornly adhered poplar fluff fibers. The mechanical action of the brush 23 and the airflow of the hot air nozzle form a synergistic effect: the hot air reduces the adhesion of the poplar fluff, and the brush effectively sweeps the peeled impurities off the surface of the filter screen, thereby avoiding secondary adhesion. When the filter screen is cleaned, the support 33 is completely embedded in the slot 34 for storage, and then the second tank box 32 is folded along the length direction of the first tank box 31 for subsequent storage and carrying. Therefore, the portable circulating water filter screen cleaning tool provided by the embodiment of the application realizes efficient and convenient cleaning of the filter screen. The synergistic effect of the hot air assembly 1 and the brush head assembly 2 can quickly soften and peel off the impurities such as poplar fluff on the filter screen, and the design of the collection box 3 effectively avoids secondary pollution. In addition, the tool also has portability and easy operation, and is very suitable for use in places such as chemical plants where the filter screen needs to be cleaned frequently. Through simple operation steps, the cleaning work of the filter screen can be easily completed, thereby ensuring the smooth operation of the circulating water system, improving the production efficiency, and reducing the maintenance cost.

[0033] It should be noted that the filter screen of the present application is made of stainless steel and is relatively heavy. When the filter screen needs to be cleaned, the locking assembly 5 between the third side wall 322 and the fourth side wall 323 is first opened, so that the locking state between the third side wall 322 and the fourth side wall 323 is released, ensuring that the fourth side wall 323 can be freely turned smoothly. Then, the fourth side wall 323 is turned to a position parallel to the second bottom wall 321, i.e. to a flat state, at which time the internal space of the collecting box 3 is fully expanded and widened, providing convenience for the stable placement of the filter screen.

[0034] After the filter screen is stably placed in the collecting box 3, the fourth side wall 323 needs to be turned back to a position perpendicular to the second bottom wall 321. At this time, the third side wall 322 and the fourth side wall 323 are firmly locked by the locking assembly 5.
