The closed structure is provided with an inner cavity, a water outlet pipe orifice 1 communicated with the inner cavity is arranged on the closed structure, at least partial area of the closed structure is also provided with a pore communicated with the inner cavity, and the pore diameter of the pore is 1-50 mm. The water pump anti-blocking grid cover is mainly used for the pretreatment stage of sewage treatment, generally speaking, the pretreated sewage in a sewage pool contains a plurality of impurities, such as plastic bags, aquatic plants and the like, and large-particle silt and other impurities, and the filter cover carried by the water pump cannot completely block the impurities. If the sundries are sucked by the water pump, the water pump can be blocked, damaged or even directly burned out, the sundries can be blocked by the closed structure, the sundries are intercepted outside the closed structure, and the service life of the water pump is prolonged. Generally, the impurities cannot pass through the pores with the diameter of less than 50mm, but the impurities with the diameter of less than 1mm cannot damage the water pump, and can directly pass through the pores together with sewage to flow into the water pump and be conveyed to the next water treatment device by the water pump for further treatment.

When the device is installed, the sewage submersible sewage pump is placed in the closed structure of the water pump anti-blocking grid cover, then one end of a water outlet pipe of the sewage submersible sewage pump is connected to the pump, and the other end of the water outlet pipe extends out of the closed structure through a water outlet pipe opening 1 and is connected to a subsequent sewage treatment device. The outer diameter of the outlet pipe should be kept approximately the same as the diameter of the outlet pipe opening 1, and the outlet pipe opening 1 is preferably fixed to the closed structure, for example, the outlet pipe is clamped to the closed structure by a clamp or a steel wire, so that the outlet pipe and the closed structure do not move relatively due to vibration generated when the water pump operates, and the stability during water drainage is improved.

The working principle of the water pump anti-blocking grid cover is as follows: after the sewage submersible sewage pump is started, an impeller of the submersible sewage pump rotates at a high speed, sewage and air in the water pump are pumped out under the action of centrifugal force generated by the impeller rotating at the high speed, negative pressure is generated locally in the pump, sewage in the sewage pool converges into a water inlet of the water pump under the action of pressure, impurities and large granular impurities in the water are blocked by the closed structure and are attached to the closed structure, the impurities cannot enter the inner cavity, the sewage enters the inner cavity through the holes in the closed structure and then enters the water pump to be pumped to a subsequent treatment device.

In the above embodiment, the pore diameter of the pores may be set to be 1 to 25 mm. The water flow of the integrated water treatment facility is generally smaller, the filtering capacity of the anti-blocking grid cover is usually considered firstly, and the passing capacity of the anti-blocking grid cover is considered secondly, so the pore diameter of pores can be controlled below 25mm, and the interception performance of the pores is ensured.

In one embodiment of the present invention, the enclosed structure includes a plurality of filter plates, and the filter plates enclose an inner chamber. The filter plate generally refers to a plate having a certain porosity and capable of performing a filtering function.

The hole 3 is preferably punched by stamping, the punching opening and arrangement are uniform, the mechanical punching efficiency is high, and the stability is good. The perforated plate 2 is preferably removable to facilitate maintenance and replacement of the pump. If the sewage is neutral, the porous plate 2 can be made of a galvanized material, and the galvanized porous plate has good corrosion resistance and oxidation resistance and is relatively low in manufacturing cost. The holes 3 on the porous plate 2 can be made into micropores with small aperture, so that the porous plate 2 structure is more suitable for domestic sewage with large water inlet pollution, multiple impurity types and complex physicochemical properties.

In the above embodiment, the perforated plate 2 may be a rectangular perforated plate.

The thickness size of rectangle porous plate is many, but the utility model discloses a water pump prevents stifled bars cover mainly is the protection water pump, does not need very high intensity, and the flow that general small-size sewage stealthily defiles the pump and draws water can not exceed 10t/h, and 1 mm's thickness can bear the water pump completely and take out the impact of intaking when sewage to the rectangle porous plate, stealthily dirty pump to the great sewage of flow, and the rectangle porous plate of 15mm thickness also satisfies the user demand completely.

In the above embodiment, the plurality of wells 3 are at least either in a straight row or in a 60 ° staggered row or in a 45 ° staggered row on the rectangular porous plate. The holes 3 of the perforated plate 2 are typically regularly arranged, and may be arranged to be staggered by 60 ° in general. The 60-degree staggered arrangement is generally called plum blossom arrangement, and means that 6 holes 3 with the same distance are adjacent to the periphery of one hole 3, and the included angle between the connecting lines of the adjacent holes 3 and the middle hole 3 is 60 degrees, and the 60-degree staggered arrangement has the advantages of attractive appearance, high opening density and the like. Of course, the holes 3 can also be arranged in a straight line as shown in fig. 1 and fig. 2, or arranged in a 45-degree staggered manner, the straight line arrangement has the minimum punching cost, and the 45-degree staggered arrangement has the same attractive appearance and is more labor-saving.
