Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a conical sedimentation hopper casting device for a water plant flocculation sedimentation tank. Background Technology

[0002] In the traditional water plant flocculation sedimentation tank bottom sludge hopper secondary structure pouring process in hydraulic engineering, the tank wall height is 5.3m, and the sludge hopper secondary structure is located at the bottom of the tank with a height of 0.89m. Using the traditional sludge hopper pouring method, it is impossible to pour the concrete to the designed height in one go. Because it is impossible to install formwork at the bottom of the tank, the concrete cannot be poured to the designed height in one go. It needs to be piled up to a certain height and allowed to initially solidify before subsequent pouring work can proceed. The traditional pouring method has low construction efficiency, cannot provide a working platform for workers, affects the construction progress, and poses certain safety hazards. Using a sludge hopper pouring device, the concrete can be poured to the designed height in one go, improving construction efficiency and the appearance quality of the secondary structure. Utility Model Content

[0003] The purpose of this invention is to provide a conical sludge hopper casting device for flocculation sedimentation tanks in water plants. By setting up a top frame, top support, conical frame, bottom frame, and positioning frame, it solves the problems of traditional sludge hopper casting methods, which cannot be completed in one go. Because formwork cannot be installed at the bottom of the tank, concrete cannot be poured to the designed height in one go; it needs to be piled up to a certain height and allowed to partially solidify before subsequent pouring can be carried out. Traditional casting methods are inefficient, lack a working platform for workers, affecting construction progress and posing certain safety hazards. The sludge hopper casting device allows for one-time casting to the designed height, improving construction efficiency and the appearance quality of the secondary structure.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a conical sludge hopper casting device for a flocculation sedimentation tank in a water plant, comprising a top frame, a top bracket welded to the inner wall of the top frame, a conical frame welded to the lower surface of the top frame, a bottom frame welded to the bottom end of the conical frame, a positioning frame welded to the middle of the conical frame, and a support rod welded to the surface of the positioning frame.

[0005] Preferably, the surface of the top frame is wrapped with an A-ring, and the top wooden mold is fixedly installed on the top frame through the A-ring.

[0006] Preferably, a threaded seat is welded to the upper surface of the top frame, a sleeve is threadedly connected to the surface of the threaded seat, and a lifting ring is welded to the upper surface of the sleeve.

[0007] Preferably, the surface of the conical frame is wrapped with B-rings, and the conical frame is fixedly installed with a fully enclosed wooden mold through the B-rings.

[0008] Preferably, a bottom mold is fixedly installed on the lower surface of the bottom frame, and the support rod is welded to the lower surface of the top frame.

[0009] This utility model provides a conical sludge hopper casting device for a flocculation sedimentation tank in a water plant, which has the following features:

[0010] Beneficial effects:

It is lowered to the bottom of the flocculation sedimentation tank by a hoisting device for the pouring of the secondary structure of the sedimentation hopper. There is a 20cm gap between the sedimentation hopper pouring device and the four corners of the tank to facilitate concrete pouring and to facilitate the use of a vibrator to compact the concrete. A template is fixed on the cross-section of the sedimentation hopper pouring device to provide a working surface for the workers, which is convenient for construction. The device has a simple structure, small size, light weight, low manufacturing cost, and is easy to install and use. Moreover, the device is easy to manufacture and can be made on-site according to local conditions, which can speed up the construction progress and maintain the quality of the secondary concrete pouring of the sedimentation hopper.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, this embodiment proposes a conical sludge hopper casting device for a flocculation sedimentation tank in a water plant, including a top frame 1, a top bracket 2 welded to the inner wall of the top frame 1, a conical frame 3 welded to the lower surface of the top frame 1, a bottom frame 4 welded to the bottom end of the conical frame 3, a positioning frame 5 welded to the middle of the conical frame 3, and a support rod 6 welded to the surface of the positioning frame 5. The top frame 1, top bracket 2, conical frame 3, bottom frame 4, positioning frame 5, and support rod 6 are all made of φ10 steel bars bent and welded to form a conical frame. During construction, it is lowered to the bottom of the flocculation sedimentation tank, and personnel above the device pour and vibrate the concrete.

[0022] The surface of the top frame 2 is wrapped with hoop 7. The top wooden formwork 8 is fixedly installed on the top frame 2 through the hoop 7. The hoop 7 fixes the top wooden formwork 8 and provides a working surface for personnel. Personnel can pour and vibrate concrete from above. The top wooden formwork 8 is supported by the bottom top frame 2 to prevent collapse.

[0023] A threaded seat 9 is welded to the upper surface of the top frame 2. A sleeve 10 is threadedly connected to the surface of the threaded seat 9. A lifting ring 11 is welded to the upper surface of the sleeve 10. The equipment is lowered to the bottom of the flocculation sedimentation tank by using the lifting ring 11 in conjunction with the lifting equipment. After the sleeve 10 is installed, it can exert a downward pressure effect, thereby improving the fixing effect between the top frame 2 and the top wooden mold 8.

[0024] The surface of the conical frame 3 is wrapped with B-rings 12. The fully enclosed wooden mold 13 is fixedly installed on the conical frame 3 through the B-rings 12. The fully enclosed wooden mold 13 is fixed to the conical frame 3 through the B-rings 12, which has the effect of forming a conical groove after the concrete is poured, and also reduces the seepage of the concrete.

[0025] The bottom mold 14 is fixedly installed on the lower surface of the bottom frame 4, and the support rod 6 is welded to the lower surface of the top frame 2.

[0026] Specifically, the cone-shaped sludge hopper casting device for the flocculation sedimentation tank of this water plant operates as follows: During use, a frame is formed by welding multiple φ10 steel bars. The surface around the truncated cone is fixed with a template. It is lowered to the bottom of the flocculation sedimentation tank using a hoisting device for casting the secondary structure of the sludge hopper. A 20cm gap exists between the casting device and the four corners of the tank, facilitating concrete pouring and compaction with a vibrator. A template is fixed to the cross-section of the casting device to provide a working surface for workers, simplifying construction. This device has a simple structure, is small, lightweight, low-cost, and easy to install and use. Its simple construction allows for on-site fabrication, accelerating construction progress while maintaining the quality of the secondary concrete casting. Furthermore, the device provides a working surface for workers on top of the tank, facilitating their work.
