Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a grille device for an integrated sewage treatment pump station. Background Art

[0002] The integrated sewage treatment pump station grille is an important equipment used in sewage treatment. Its main function is to intercept and remove suspended matter, floating matter and impurities in sewage to ensure the smooth progress of subsequent treatment processes. The integrated sewage treatment pump station grille is usually composed of multiple bars, which are arranged at a certain interval to form a barrier. When sewage passes through the grille, larger suspended matter and floating matter are intercepted in front of the grille, while smaller impurities flow out through the gaps in the grille. This can reduce the burden of subsequent treatment processes to a certain extent and improve sewage treatment efficiency.

[0003] After searching, it was found that a filter cleaning device for central air-conditioning maintenance was disclosed in the Chinese Public Utility Model Patent Application No.: CN216584238U, which involves the field of sewage treatment devices. Guide strips, buffer pads, connecting rods, sleeves, limit rings, third springs and other components are designed inside the pump station body and matched with the guide ring added to the grille. Not only does it play a good guiding role for the grille, but it also makes the guide ring on the grille always fit with the inner wall of the pump station body to prevent debris in the sewage from leaking out from between the grille and the inner wall of the pump station body. In addition, the buffer pads, connecting rods, sleeves, limit rings, third springs and other components play a buffering role when the grille settles.

[0004] However, when the traditional integrated sewage treatment pump station screen device is used, large impurities will block the screen, making it difficult for sewage to flow. If the above solution uses a crushing knife to crush the large impurities, the crushed impurities can easily pass through the screen device into the pump station, which will cause more burden on the use of the pump station. For this reason, we propose a screen device for an integrated sewage treatment pump station. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A grille device for an integrated sewage treatment pump station comprises a pump station body and a grille box, wherein a water inlet pipe is fixedly connected to the left side of the pump station body, a mounting port plate is fixedly connected to the left side of the grille box, a waterproof box is fixedly connected to the rear of the grille box, a waterproof motor is fixedly connected to the lower right side of the inner wall of the waterproof box, a worm is fixedly connected to the output end of the waterproof motor, a worm is meshingly connected to the rod wall of the worm, a rotating shaft is fixedly connected to the inner wall of the worm wheel, a first filter is fixedly connected to the rod wall of the rotating shaft, and a lifting mechanism with a variable covering range is provided on the top surface of the grille box. During the use of the grille device, the first filter will filter the sewage in the water inlet pipe. When cleaning is required, the first filter will be away from the water inlet pipe, so that the filtered impurities enter the grille box. At this time, the first filter returns to its original position, and the filtered impurities are accumulated below the grille box through the lifting device, thereby ensuring the normal flow of sewage above the grille box.

[0007] Furthermore, the lifting mechanism includes a submersible motor fixed to the rear side of the top surface of the grille box, the output end of the submersible motor is fixedly connected to a screw rod, the rod wall of the screw rod is threadedly connected to a second filter screen, and the left side of the inner wall of the grille box is fixedly connected to a limiting rod.

[0008] Furthermore, the mounting port plate is fixed to the left side of the inner wall of the pump station body by bolts, the left end of the worm is rotatably connected to the left side of the inner wall of the waterproof box, the rear end of the rotating shaft is rotatably connected to the rear side of the inner wall of the waterproof box, the front end of the rotating shaft penetrates the front side of the inner wall of the waterproof box and the rear of the grille box, extends to the inner wall of the grille box and is rotatably connected to the front side of the inner wall, the output end of the submersible motor extends the inner wall of the grille box, the lower end of the screw is rotatably connected to the lower side of the inner wall of the grille box, and one end of the limit rod penetrates one side of the second filter screen and extends to the other side thereof.

[0009] Furthermore, limit blocks are fixedly connected to the lower parts of the left and right sides of the inner wall of the grille box.

[0010] Furthermore, a lifting rod is fixedly connected to the center of the top surface of the grille box.

[0011] Furthermore, support feet are provided at the four corners of the bottom surface of the grid box, and a plurality of the support feet are in contact with the lower side of the inner wall of the pump station body.

[0012] Furthermore, the first filter screen and the second filter screen are both made of stainless steel.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. When the grille device is used, sewage enters the water inlet pipe. Under the action of the first filter, larger impurities will be blocked. At this time, sewage containing smaller impurities enters the pump station body through the first filter and the grille box. In order to avoid blockage at the water inlet pipe, it is necessary to regularly deal with the large impurities here. When cleaning large impurities, start the submersible motor. The submersible motor moves the second filter to the uppermost side of the inner wall of the grille box through the screw. Then, start the waterproof motor. Under the transmission action of the worm gear, the first filter rotates to the upper side of the inner wall of the grille box. At this time, under the continuous discharge of sewage from the outside, large impurities will enter the grille box. By starting the waterproof motor to rotate in the opposite direction, the first filter returns to the hole of the installation plate to filter the water inlet pipe again. Finally, start the submersible motor again to move the second filter back to its original position, and clean the large impurities entering the grille box during the movement, so that the large impurities are accumulated below the grille box, thereby not hindering the flow of sewage above the grille box.

[0015] 2. Make the connection between the various devices in the equipment more closely, improve the safety and stability of the equipment, and increase the performance and effect of the equipment.

[0016] 3. The limit block enables the second filter to move to a fixed position below the grille box, which can provide a larger space for the grille box to accommodate large impurities. The lifting rod is driven by the lifting device to facilitate the grille box to be moved out of the pump station body, so as to facilitate the cleaning of impurities in the grille box. The contact between the support foot and the pump station body can avoid the loose connection between the installation plate and the pump station body due to the heavy grille box. The first filter and the second filter have high waterproof and anti-corrosion properties, which increases the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
