Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a submersible pump installation structure for a high-density sedimentation tank. Background Art

[0002] High-density sedimentation tanks are an important part of sewage treatment, playing the role of reducing hardness and flocculation sedimentation. The sludge on the filler often needs to be flushed, otherwise it will affect the effluent quality and cause an increase in suspended matter. At the same time, the deposited sludge increases the load on the filler and support, posing a risk of collapse. Two incidents of support sinking and collapse have occurred.

[0003] In the past, two submersible pumps were needed to clean the sludge in the pool, one to pump water to disperse the sludge, and the other to pump away the sludge. Since there was no lifting equipment on the high-density sedimentation tank, the installation of the submersible pump was entirely manual, requiring the on-duty personnel to cooperate with four workers during the shift change to complete the installation. After the cleaning was completed, four people were required to lift the submersible pump out of the pool. In addition, the position of the submersible pump needed to be adjusted many times when pumping sludge, and the pump needed to be repeatedly lifted and lowered, which brought heavy physical labor and unsafe factors to the on-duty personnel.

[0004] Based on the above technical problems, the inventors proposed a high-density sedimentation tank submersible pump installation structure in combination with the structural characteristics of the high-density sedimentation tank. The submersible pump can be transferred, lifted, and lowered by two people, and the operation is convenient, saving time and effort. Utility Model Content

[0020] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0021] like Figure 1 , 2As shown, the utility model includes a moving beam 14 arranged along the width direction of the high-density sedimentation tank 1 and capable of reciprocating along the length direction of the high-density sedimentation tank 1. A through hole 10 is arranged at the center of the moving beam 14. A storage cylinder 9 for placing a submersible pump passes through the through hole 10. The top surface of the storage cylinder 9 is open, and a bottom support plate 11 is arranged on the bottom surface of the storage cylinder 9. Water-permeable holes are evenly distributed on the cylinder wall of the storage cylinder 9 and on the bottom support plate 11. A power mechanism for driving the storage cylinder 9 to rise and fall is arranged on the moving beam 14.

[0022] In this embodiment, a portal frame 7 is installed on the top surface of the moving beam 14, two fixed pulleys 8 are installed on the portal frame 7, a traction rope 6 is fixed on both sides of the storage tube 9, the two traction ropes 6 are respectively passed around the two fixed pulleys 8, and the end of each traction rope 6 is connected to the winder 5. The winder 5 adopts the existing structure, and the electric winder 5 is preferably used.

[0023] In this embodiment, in order to facilitate the installation of the wire winder 5, the support bases 3 are fixedly installed at both ends of the moving beam 14, and the wire winder 5 is installed on the horizontal plate of the support base 3. Furthermore, in order to facilitate the dragging of the moving beam 14, a handle 4 is fixed on the horizontal plate of each support base 3, and the worker can hold the handle 4 to push and pull the moving beam 14 to achieve displacement.

[0024] In this embodiment, in order to prevent the storage tube 9 from hard contact with the pool bottom when descending, a buffer plate 12 is provided below the bottom supporting plate 11 , and the buffer plate 12 is connected to the bottom supporting plate 11 via a plurality of springs 13 .

[0025] In this embodiment, the area of ​​the bottom supporting plate 11 is larger than the area of ​​the through hole 10 .

[0026] In this embodiment, in order to realize the reciprocating movement of the moving beam 14 along the length direction of the high-density sedimentation tank 1, slide bars 15 are installed at positions opposite to the tank walls on both sides of the high-density sedimentation tank 1, and each slide bar 15 is covered with a slide sleeve 16, and each end of the moving beam 14 is connected to the slide sleeve 16. Both ends of the slide bar 15 are respectively connected to the fixed plate 2, and the fixed plate 2 is fixed to the tank wall.

The workers can hold the handle 4 to push and pull the moving beam 14 to move, and accordingly adjust the position of the submersible pump, making it easy to move. When the submersible pump moves to a suitable position, the moving beam 14 stops moving, and the worker uses the winder 5 to slowly lower the storage tube 9 to the bottom of the tank to perform cleaning operations. After cleaning, the worker uses the winder 5 to pull the storage tube 9 to its original position.

[0028] The present application adopts the innovative design of the installation structure, and the transfer, lifting and lowering of the submersible pump can be completed by two people, which is convenient to use. At the same time, the lifting and lowering of the pump are mainly completed with the help of the electric winder 5, which saves time and effort.
