Description

Technical Field

[0001] The present application relates to the technical field of filter cleaning devices, and in particular to a filter mesh spraying system. Background Art

[0002] In the related art, water is used to flush the water residue filter. During water flushing, since water has certain adsorption and tension, and the pores of the water residue filter mesh are small, a water film will be formed on the filter mesh. The water residue is also a fine particle, which often causes the problem of incomplete flushing. Once the flushing is not thorough, the filter mesh may be clogged. In addition, the use of water for flushing is large, which will increase the water treatment cost. Due to the fluidity of water, the flushed water residue will flow to the edge of the filter during the flushing process and accumulate, causing the edge of the filter mesh to be clogged.

[0016] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0017] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0018] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0019] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0020] In response to the above problems, an embodiment of the present application provides a filter mesh spraying system that can reduce the amount of flushing water used, lower water treatment costs, and improve cleaning effects.

[0021] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1 The filter mesh spraying system includes a mounting bracket 1, a spraying pipe 2, and a control mechanism; the mounting bracket 1 is fixedly mounted on the rack at both ends of the filter screen 10, the spraying pipe 2 is mounted between the ends of the two mounting brackets 1, and the spraying pipe 2 is on one side of the circumference of the filter screen 10 and is arranged axially parallel to the filter screen 10. Nozzles 3 are evenly installed on one side of the spraying pipe 2 close to the filter screen 10, and the middle part of the other side of the spraying pipe 2 is connected to an inlet pipe 4, and the three-way joint on the inlet pipe 4 is respectively connected to the water inlet pipe 5 and the air inlet pipe 6, the other end of the water inlet pipe 5 is connected to the water supply device, and a water pump 7 is installed on the water inlet pipe 5, and the other end of the air inlet pipe 6 is connected to the air supply mechanism 8, and the water pump 7 and the air supply mechanism 8 are respectively electrically connected to the control mechanism.

[0023] During operation, the control mechanism controls the water pump 7 to start pumping water, and the water flows into the spray pipe 2 through the water inlet pipe 5 and the inlet pipe 4, and then flushes the filter screen 10 through the nozzle 3. Since the mesh of the filter screen 10 is small, a water film containing water residue will be formed on the filter screen 10. At this time, the control mechanism controls the air supply mechanism 8 to start spraying, and the gas enters the spray pipe 2 through the air inlet pipe 6 and the inlet pipe 4, and then is sprayed out through the nozzle 3 to further spray the filter screen 10, and break the water film on the filter screen 10, taking away the water residue wrapped therein. The continuously sprayed airflow acts on the flushing water, and can also prevent the water residue after flushing from being driven by the water flow to flow to the edge of the filter and accumulate, thereby improving the flushing effect. The mixed air-water flushing can also avoid the problem of water residue flying and affecting the on-site environment caused by air flushing alone.

[0024] In some embodiments, the nozzle 3 is a spiral nozzle, and the arrangement length of the nozzle 3 on the spray pipe 2 is greater than the axial length of the filter screen 10 of the filter.

[0025] When working, the spiral nozzle has a larger spraying range. The installation position of the nozzle 3 covers the axial direction of the filter screen 10 of the filter, which increases the flushing range and avoids blockage caused by dead corners during the flushing process.

[0026] In some embodiments, an electric valve 9 is installed on the water inlet pipe 5 near the three-way joint, and the electric valve 9 is electrically connected to the control mechanism.

[0027] During operation, when water flushing is performed, the control mechanism controls the electric valve 9 to open, and when air flushing is performed, the control mechanism promptly controls the electric valve 9 to close, to prevent the water flow in the water inlet pipe 5 from affecting the flushing effect of the air flushing, and to prevent the air flow from being diverted into the water inlet pipe 5, thereby reducing the blowing pressure of the air flushing and affecting the flushing effect of the air flushing.

[0028] In some embodiments, the water and air inlet pressure at the inlet pipe 4 is greater than 0.6 MPa.

[0029] During operation, the water and air inlet pressure at the inlet pipe 4 is greater than 0.6MPa, which can ensure that the water flow or gas has sufficient pressure after entering the blowing pipe 2, making the water flow or gas in the blowing pipe 2 more evenly distributed, and ensuring that flushing water or blowing gas is discharged from each nozzle 3, thereby improving the flushing effect.

[0030] Finally, it should be noted that, in this document, relationships such as first and second, etc., are used solely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
