Description

Technical Field

[0001] This utility model relates to a flow regulating valve device for a sludge suction machine. Specifically, this utility model discloses a flow regulating valve device for a peripheral drive sludge suction machine that can stably discharge sludge. Background Technology

[0002] Circular radial flow sedimentation tanks are an important treatment facility widely used in large and medium-sized wastewater treatment plants. Peripheral drive sludge suction machines can remove the settled sludge from the circular sedimentation tank. Wastewater enters the tank through a central column pipe and flows continuously to the perimeter, during which time sediments are separated from the water.

[0003] The current flow control valve body is made by drilling a rectangular hole in the side of a steel pipe. The valve body extends into the outlet of the suction pipe. By adjusting the distance the valve body extends into the suction pipe, the degree of overlap between the rectangular hole on the valve body and the suction pipe can be adjusted, thus adjusting the size of the rectangular hole and controlling the amount of mud discharged from the suction pipe. However, because the current flow control valve has a rectangular hole on the side of the valve body, when impacted by mud and water inside the suction pipe, the uneven impact force often causes the flow control valve to shake. The screw controlling the up-and-down movement of the flow control valve will also shake, causing the screw to slip and move downwards. This causes the flow control valve to move downwards as well, increasing the overlap between the rectangular hole on the valve body and the suction pipe. Eventually, they will completely overlap, closing the suction pipe and preventing mud and water discharge, thus preventing the sludge suction machine from working properly. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a flow regulating valve device for a peripheral drive sludge suction machine that can stably discharge sludge.

[0005] According to the technical solution provided by this utility model, the flow regulating valve device of the peripheral transmission sludge suction machine that can stably discharge sludge includes a working bridge, a driving component, a sludge suction pipe, a radial sludge collection trough, a central sludge collection trough, a central column, a sludge discharge pipe, and a flow regulating valve. The inner end of the working bridge is connected to the central column via a slewing bearing. The driving component is installed at the outer end of the working bridge. The central mud collection trough is fixed at the inner end of the working bridge. The radial mud collection trough is fixed on the working bridge outside the central mud collection trough. The radial mud collection trough is connected to the central mud collection trough, and the bottom surface of the radial mud collection trough is inclined. The suction pipe is fixed on the working bridge, and the outlet end of the suction pipe is vertically set. The outlet end of the suction pipe extends vertically into the radial mud collection trough. The discharge pipe is fixed to the central column and is connected to the central mud collection trough. The flow regulating valve is a cone with an upper diameter larger than its lower diameter. The flow regulating valve extends into the outlet end of the suction pipe and can move up and down under external force. The flow regulating valve and the outlet end of the suction pipe are coaxially arranged.

[0006] Preferably, a radial sludge collection trough cover plate is fixed on the radial sludge collection trough, and a screw seat is also fixed on the upper surface of the radial sludge collection trough cover plate. A screw mounting hole is opened in the screw seat, and a screw is installed in the screw mounting hole. The lower end of the screw is fixed to the upper end of the flow regulating valve, and the screw and the flow regulating valve are coaxially arranged.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] A flow regulating valve device for a peripheral drive sludge suction machine capable of stable sludge discharge, such as Figure 1-5 As shown, it includes a working bridge 1, a drive component 2, a suction pipe 3, a radial sludge collection trough 4, a central sludge collection trough 5, a central column 6, a discharge pipe 7, and a flow regulating valve 8; The inner end of the working bridge 1 is connected to the central column 6 via a slewing bearing. The driving component 2 is installed at the outer end of the working bridge 1. The central mud collection trough 5 is fixed at the inner end of the working bridge 1. The radial mud collection trough 4 is fixed on the working bridge 1 outside the central mud collection trough 5. The radial mud collection trough 4 is connected to the central mud collection trough 5, and the bottom surface of the radial mud collection trough 4 is inclined. The suction pipe 3 is fixed on the working bridge 1, and the outlet end of the suction pipe 3 is vertically set. The outlet end of the suction pipe 3 extends vertically into the radial mud collection trough 4. The discharge pipe 7 is fixed to the central column 6 and is connected to the central mud collection trough 5. The flow regulating valve 8 is a cone with an upper diameter larger than its lower diameter. The flow regulating valve 8 extends into the outlet end of the suction pipe 3 and can move up and down under external force. The flow regulating valve 8 and the outlet end of the suction pipe 3 are coaxially arranged.

[0018] A radial sludge collection trough cover plate 4.1 is fixed on the radial sludge collection trough 4. A screw seat 9 is also fixed on the upper surface of the radial sludge collection trough cover plate 4. A screw mounting hole is opened in the screw seat 9, and a screw 10 is installed in the screw mounting hole. The lower end of the screw 10 is fixed to the upper end of the flow regulating valve 8, and the screw 10 and the flow regulating valve 8 are coaxially arranged. By rotating the screw 10 by external force, the flow regulating valve 8 moves up and down.

[0019] The upper end diameter of the flow regulating valve 8 is smaller than the upper end inner diameter of the suction pipe 3.

[0020] A flow regulating valve cover plate 8.1 is fixed to the upper end face of the flow regulating valve 8. The diameter of the flow regulating valve cover plate 8.1 is larger than the outer diameter of the upper end of the suction pipe 3. The flow regulating valve 8 can act as a guide, allowing the upper end of the flow regulating valve 8 to fully extend into the suction pipe 3, so that the flow regulating valve cover plate 8.1 is completely in contact with the top surface of the suction pipe 3. The mud and water in the suction pipe 3 cannot flow into the mud collection tank 4, ultimately achieving the function of closing the valve.

[0021] The number of suction pipes 3 is several, and the lower end of the suction pipe 3 has a flared mud inlet.

[0022] The peripheral drive sludge suction machine drives the working bridge 1 to rotate around the center of the sedimentation tank via the drive component 2 at the side of the tank. This, in turn, drives the rotation of several vertically arranged sludge suction pipes 3. The sludge suction machine uses static pressure to discharge the settled sludge through the suction pipes 3 into the radial sludge collection trough 4 on the liquid surface, and then collects it in the central sludge collection trough 5. Finally, it discharges the sludge out of the sedimentation tank through the rectangular hole on the central column 6 and the pre-embedded sludge discharge pipe 7. The sludge discharge rate can be controlled by the flow regulating valve 8 at the outlet of the suction pipe 3, allowing for adjustment of the sludge discharge volume.

[0023] This invention controls the amount of mud discharged from the suction pipe 3 by changing the gap between the flow regulating valve 8 and the outlet of the suction pipe 3 through the up-and-down movement of the flow regulating valve 8. Since the conical flow regulating valve 8 and the suction pipe 3 are coaxially arranged, the gap between the flow regulating valve 8 and the outlet of the suction pipe 3 is evenly distributed, and the impact of the mud and water in the suction pipe 3 is also uniform, which will not cause the screw 10 to shake, thus preventing the screw 10 from slipping and moving downward, and the flow regulating valve 8 will not move downward.

[0024] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
