Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a device for removing suspended solids in a pool. Background Technology

[0002] In the secondary treatment system of a wastewater treatment plant, the sedimentation tank separates the activated sludge from the treated water through gravity sedimentation, thus clarifying the wastewater. This process effectively removes most suspended solids and some dissolved pollutants, ensuring effluent quality. However, due to seasonal changes, a large amount of suspended solids and non-dissolving foreign matter, such as fallen leaves and catkins, remain in the tank, causing blockage of the sludge suction port and preventing normal sludge discharge. Manual removal of suspended solids and non-dissolving foreign matter is necessary for the equipment to operate normally. However, manual removal results in a poor working environment, slow work efficiency, and extremely high safety risks. Summary of the Invention

[0003] To address the problem of large amounts of suspended solids in existing water treatment sedimentation tanks that are difficult to manually remove, this invention provides a device for removing suspended solids from sedimentation tanks. By incorporating an adjustable retrieval rod, frame, net, and auxiliary moving device, it facilitates the rapid retrieval of suspended solids in sedimentation tanks, thereby improving efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A device for removing suspended solids in a pool includes a retrieval rod, a frame, and a net. The retrieval rod and the frame are fixed, the length of the retrieval rod is adjustable, and the size of the frame is adjustable. The net is pocket-shaped, with the open end of the net fixed to the frame, and the bottom of the net has a detachable structure. An auxiliary moving device is provided at the lower part of the frame.

[0006] Furthermore, the retrieval rod comprises multiple sections arranged linearly, with each section sequentially fitted into and sliding within the preceding section. By using multiple sections, the length of the retrieval rod is adjustable, facilitating the retrieval of suspended objects at greater distances.

[0007] Furthermore, each section of the pole has multiple holes along its length, and at least one hole in each pole is fitted with a bolt for secure connection to an adjacent pole. This facilitates length adjustment and fixation of the retrieval pole, making it convenient to use.

[0008] Furthermore, the frame includes multiple extendable connecting rods forming a rectangular structure. Each connecting rod includes a connecting pipe and a connecting rod, with the connecting rod fitting into the connecting pipe. Both the connecting rod and the connecting pipe are equipped with multiple connecting rings for connecting the mesh. The size of the frame can be adjusted according to the liquid level and the amount of suspended solids in the sedimentation tank.

[0009] Furthermore, the connecting rod is equipped with a sliding device for connecting the connecting ring. The sliding device includes multiple sliders, and the connecting rod has a groove in which the sliders slide. Each slider is rotatably connected to a connecting ring, and each slider also has a screw at its center. The screw passes through the slider and abuts against the inside of the connecting rod. The connecting ring facilitates connection to the net, and the grooves and sliders on the connecting rod allow the net to move with the connecting rod when adjusting the frame size, facilitating adjustment and preventing the net from being fixed to the connecting rod during adjustment, thus preventing interference with the adjustment of the connecting rod.

[0010] Furthermore, a rubber pad is fixed to the inner surface of the connecting rod where it abuts against the screw, and the screw abuts against the rubber pad. When the slider needs to be fixed, the screw abuts against the rubber pad, increasing the friction between the screw and the rubber pad and improving the stability of the slider when fixed.

[0011] Furthermore, the connecting pipe has multiple holes along its length, and at least one hole contains a bolt for fixed connection with the connecting rod. This facilitates adjustment of the connecting rod and improves the stability of the frame during use.

[0012] Furthermore, the auxiliary moving device includes telescopic rods and wheels. At least two telescopic rods are provided at the lower part of the frame, and a wheel is fixed to the bottom of each telescopic rod. The telescopic rods and wheels allow for adjustment of the frame's height according to the sedimentation tank's liquid level, while also facilitating the frame's movement.

[0013] Furthermore, the telescopic rod includes a sleeve and a support rod. The sleeve is fixed to the bottom of the frame, and the support rod is fitted onto the lower part of the sleeve. The sleeve has multiple holes along its length, and a bolt is installed in one of the holes. The bolt is connected to the support rod.

[0014] Furthermore, a reinforcing rod is inclinedly provided on the frame, and the reinforcing rod is connected to the retrieval rod; the bottom of the net is open, and the bottom of the net is fixed by ropes or fasteners. When there are too many suspended objects retrieved in the net and they cannot be discharged from the frame, the suspended objects can be discharged from the bottom of the net by untying the ropes or fasteners.

[0015] The beneficial effects of this utility model through the above technical solution are:

[0016] This invention facilitates the retrieval of suspended solids in sedimentation tanks by incorporating a retrieval rod, frame, net, and auxiliary moving device, thereby improving manual efficiency. The multi-section rod allows for easy adjustment of the retrieval rod length based on the distance of suspended solids. The connecting pipe and rod allow for adjustment of the frame's length and width based on the liquid level and the amount of suspended solids in the sedimentation tank, reducing the number of retrieval attempts and increasing efficiency. The sliding groove and slider on the connecting rod prevent the net from interfering with the adjustment of the connecting rod's length. The telescopic rod and wheels at the bottom of the frame allow for adjustment of the frame height according to the liquid level, and also facilitate movement when there are many suspended solids in the net, saving manpower.

[0023] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0024] like Figures 1-5As shown, a device for removing suspended solids in a pond includes a retrieval rod 1, a frame, and a net 5. The retrieval rod 1 is fixed to the frame, and its length is adjustable to accommodate the distance of suspended solids in the pond. The frame can be adjusted in size to accommodate varying amounts of suspended solids, reducing the number of retrieval attempts and improving efficiency. The net 5 has a pocket-shaped structure, with its open end fixed to the frame and its bottom detachable. Specifically, the bottom of the net 5 is open and secured by telescopic or fastening buckles 6. When there are too many suspended solids in the net 5 to drain from the frame, the detachable bottom of the net 5 assists in unloading the suspended solids. An auxiliary moving device is provided at the bottom of the frame to assist in moving the frame when there are too many or too large suspended solids in the net 5, improving the overall effectiveness.

[0025] The retrieval rod 1 comprises multiple rod sections 11 arranged linearly. Each rod section 11 is sequentially fitted into and slides within the preceding rod section 11, with the foremost rod section 11 fixed to the top of the frame. By using multiple rod sections 11, the length of the retrieval rod 1 is adjustable, facilitating the retrieval of suspended objects at greater distances. To improve the stability of the retrieval rod 1 after length adjustment, each rod section 11 has multiple holes along its length, and at least one hole in each rod section 11 is fitted with a bolt 7 for fixed connection to the adjacent rod section 11.

[0026] The frame includes multiple extendable connecting rods 2, which form a rectangular structure. Each connecting rod 2 includes a connecting pipe 21 and a connecting rod 22. The connecting rod 22 is fitted into the connecting pipe 21. Both the connecting rod 22 and the connecting pipe 21 are provided with multiple connecting rings 8 for connecting the net 5. The size of the frame can be adjusted according to the liquid level and the amount of suspended solids in the sedimentation tank. Multiple holes are opened along the length of the connecting pipe 21, and a bolt 7 is installed in at least one hole of the connecting pipe 21 to fix it to the connecting rod 22. This facilitates the adjustment of the connecting rod 2 and the fixation of the connecting pipe 21 and the connecting rod 22, improving the stability of the frame during use.

[0027] To prevent the mesh 5 from being fixed to the connecting rod 22 during the adjustment of the rod 11, thus affecting the adjustment length of the connecting rod 2, the connecting rod 22 is provided with a sliding device for connecting the connecting ring 8. The sliding device includes multiple sliders 24, and the connecting rod 22 has a sliding groove 23. The multiple sliders 24 slide in the sliding groove 23. Each slider 24 is rotatably connected to the connecting ring 8. Each slider 24 has a screw 25 in the middle. The screw 25 can pass through the slider 24 and abut against the inside of the connecting rod 22, which facilitates fixing the adjusted slider 24 and prevents the mesh 5 from moving with the slider 24 during use, thus affecting the use effect.

[0028] Furthermore, a rubber pad 26 is fixed to the inner surface of the connecting rod 22 that abuts against the screw 25, and the screw 25 abuts against the rubber pad 26. When the slider 24 needs to be fixed, the screw 25 abuts against the rubber pad 26, increasing the friction between the screw 25 and the rubber pad 26, and improving the stability of the slider 24 when fixed.

[0029] The lower part of the frame is also provided with an auxiliary moving device to assist the movement of the frame and the net 5. The auxiliary moving device includes a telescopic rod 3 and a wheel 4. Specifically, at least one telescopic rod 3 is fixed to the bottom of the connecting pipe 21 and the connecting rod 22 of the connecting rod 2 at the bottom of the frame. The wheel 4 is fixed to the bottom of the telescopic rod 3. By setting the telescopic rod 3 and the wheel 4, the height of the telescopic rod 3 can be adjusted according to different liquid levels in the sedimentation tank. Each telescopic rod 3 includes a sleeve 31 and a support rod 32. The sleeve 31 is fixed to the bottom of the connecting pipe 21 and the connecting rod 22 of the connecting rod 2 at the bottom of the frame. The support rod 32 is fitted to the lower part of the sleeve 31. The sleeve 31 has multiple holes along its length, and at least one hole is provided with a bolt 7. The bolt 7 is connected to the support rod 32.

[0030] To improve the overall stability of the salvage device, a reinforcing rod 9 is obliquely arranged between the frame and the salvage rod 1. One end of the reinforcing rod 9 is fixed to the connecting pipe 21 of the connecting rod 2 at the bottom of the frame, and the other end is fixedly connected to the rod 11 fixed to the frame.

[0031] When in use, the operator holds the retrieval rod 1 and aligns the frame with the suspended object to retrieve it, or the retrieval rod 1 can be fixed to an existing mobile device or retrieval equipment for retrieval.

[0032] When it is necessary to adjust the length of the salvage rod 1, the length of the salvage rod 1 is adjusted by fixing the bolts 7 on different rod bodies 11 into holes at different positions on the rod body 11 and connecting them to the adjacent rod body 11.

[0033] When the size of the frame needs to be adjusted, slide the connecting rod 22 inside the horizontally or vertically arranged connecting pipe 21. After the connecting rod 22 extends or retracts to an appropriate position outside the connecting pipe 21, fix the connecting rod 22 to the connecting pipe 21 with the bolt 7 provided on the connecting pipe 21. At the same time, adjust the position of the slider 24 in the slide groove 23, and then fix the slider 24 to the connecting rod 22 with the screw 25. To adjust the liquid level in the sedimentation tank, the size of the frame can be adjusted, and the length of the telescopic rod 3 can also be adjusted. This is done by adjusting the position of the bolt 7 on the sleeve 31 at different holes and connecting it to the support rod 32.
