Description

Technical Field

[0001] The utility model application relates to the technical field of filter screens, in particular to a water supply and drainage anti-blocking and anti-leakage filter screen. Background Art

[0002] Water supply and drainage refers to the study of the social cycle of water, including water extraction, purification, transportation, treatment, reuse and discharge. Its main purpose is to ensure the effective use of water resources, prevent water pollution, maintain public health, and support the development of cities and industries. It is not only vital to urban construction and environmental protection, but also closely related to human health and quality of life. In order to avoid pollution of water sources by garbage carried in the water, the municipal drainage system will install filter nets in the drainage pipes or drainage channels to filter out impurities in the sewage.

[0003] When the filter net of the drainage channel in the drainage system is in use, due to the large volume of debris and garbage carried in some sewage, it is easy to cause the filter net to be blocked after being filtered, which can easily affect the normal drainage of the drainage pipe. However, most of the existing filter nets do not have an anti-blocking structure, which requires manual cleaning and dredging during use, increasing the workload of maintenance personnel. Summary of the invention

[0004] In order to solve the problem that the existing water supply and drainage filter screen is easily blocked and inconvenient to clean during use, the utility model provides a water supply and drainage anti-blocking and anti-leakage filter screen to solve the above problem.

[0006] A water supply and drainage anti-blocking and anti-leakage filter net, comprising a filter basket and a collecting basket, wherein a first supporting outer frame is fixed to an outer edge of the top of the filter basket, a second supporting outer frame is fixed to an outer edge of the top of the collecting basket, a connecting clamp is fixed to a bottom of a side of the collecting basket close to the filter basket, a clamping groove cooperating with the connecting clamp is provided at a bottom of the filter basket close to the collecting basket, limiting brackets are symmetrically fixed to a top of a side of the collecting basket close to the filter basket, and limiting brackets cooperating with the limiting bracket are symmetrically provided on a side of the filter basket close to the collecting basket.

[0007] Furthermore, the filter basket is arranged to be inclined toward the collection basket, the top of the collection basket is flush with the top of the filter basket, and the height of the collection basket is greater than the height of the filter basket.

[0008] Furthermore, fixing holes are symmetrically provided at the corners of the support outer frame 1 and the support outer frame 2, and the support outer frame 1 and the support outer frame 2 are respectively configured to be a horizontally placed "U" shape that cooperates with the filter basket and the collection basket.

[0009] Furthermore, both ends of the support outer frame 1 close to one side of the support outer frame are provided with limiting grooves, and limiting protrusions are fixed inside the limiting grooves, and both ends of the support outer frame 2 close to one side of the support outer frame are fixed with locking blocks that cooperate with the limiting grooves and the limiting protrusions.

[0010] Furthermore, an auxiliary baffle whose top surface is flush with the top surface of the collecting basket is fixed inside the collecting basket away from the filtering basket. The length of the auxiliary baffle is smaller than the length inside the collecting basket, and the thickness of the auxiliary baffle is equal to the thickness of the second supporting outer frame.

[0011] Furthermore, the snap-fitting groove and the connecting card plate are arranged in mutually matching arcs, the widths of the snap-fitting groove and the connecting card plate are both equal to the widths of the filter basket and the collection basket, and the snap-fitting block is arranged in a transversely placed "U" shape that cooperates with the limiting groove and the limiting protrusion.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, through the detachable filter basket and the collection basket, after filtering the debris, under the impact of the subsequent water flow, the debris can fall into the collection basket to avoid clogging of the filter basket. Then the collection basket can be taken out separately for cleaning, which solves the problem that the existing water supply and drainage filter is easy to be blocked and inconvenient to clean during use, and greatly improves the practicality of the filter.

[0014] 2. In the utility model, the filter basket and the collection basket can be limited vertically by the cooperation of the limiting support plate and the limiting bracket, so that the two can be quickly aligned, and then the limiting protrusion and the locking block can be cooperated to limit the two in the horizontal direction, and then the filter basket and the collection basket can be fixed by passing the bolts through the fixing holes, which is also convenient for disassembly and cleaning.
