Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge discharge valve well. Background Technology

[0002] Valve wells provide a relatively stable and safe environment for sludge discharge valves, preventing them from being directly affected by external factors such as rainwater, debris, and mechanical impacts, thus extending their service life. Traditional oxidation ditches primarily utilize the uneven distribution of dissolved oxygen within the ditch. Through proper design, alternating aerobic and anoxic zones are created within the ditch to achieve denitrification. In traditional three-ditch oxidation ditches, the frequent and brief environmental changes between aerobic and anoxic states mean that nitrifying and denitrifying bacteria are not always in their optimal growth and metabolic environment, thus affecting the treatment capacity per unit volume of the structure.

[0003] The sludge discharge from the oxidation ditch is manually controlled by valves in four valve wells at the effluent end. The sludge is discharged by gravity to the oxidation ditch sludge pumping station, and then transferred to the sludge desulfurization and thickening tank. The sludge discharge process requires frequent operation, resulting in very low sludge discharge efficiency. Furthermore, the frequent entry and exit from the valve wells poses safety hazards and is not safe enough, which needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sludge discharge valve well, which solves the technical problem that sludge is discharged by gravity to the oxidation ditch sludge pumping station, and then transferred from the oxidation ditch sludge pumping station to the sludge desulfurization and thickening tank. During the sludge discharge process, frequent operation is required, resulting in very low sludge discharge efficiency and safety hazards due to frequent entry and exit from the valve well.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mud discharge valve well includes a well body, a delivery pipe, and a mud discharge pump. One end of the delivery pipe is connected to the well body, and the other end of the delivery pipe is connected to the mud discharge pump. The well also includes:

[0007] The surface of the conveying pipe is provided with two clamps, and a sealing component is fixedly installed on the inner side of each clamp. Each sealing component includes a rubber strip and a flange gasket.

[0008] Preferably, a positioning block is fixedly installed at the top of each clamp, a positioning groove is provided at the side end of the positioning block, a sleeve plate is fixedly installed on the outer side of each clamp, a pre-tightening plate is slidably installed inside each sleeve plate, and the top of each pre-tightening plate has a conical protrusion structure.

[0009] Preferably, each of the pretensioning plates has two reset rods fixedly installed on its side end, each of the pretensioning plates has a sleeve fixedly installed on its side end, each of the sleeves has a screw that rotatably engages with the sleeve on its side end, each screw thread penetrates the interior of the sleeve, the thread helix angle of each screw and sleeve is less than the friction angle, and the surface of the conveying pipe is provided with an outwardly expanding convex ring structure.

[0010] Compared with the prior art, the present invention has the following beneficial effects;

[0011] Firstly, the sludge discharge system is composed of a well body, a conveying pipe, and a sludge pump. The well body is used to hold sludge, and the conveying pipe connects the well body and the sludge pump to realize sludge transportation. A timer switch is set on the side of the sludge pump. The pumping is started after the side ditch has settled for one hour. It can operate in both directions, shorten the sludge discharge distance, and improve the sludge discharge efficiency.

[0012] Secondly, the reset rod generates a reverse force, which pushes the pre-tightening plate into the positioning block to first position the clamp. Then, the screw is rotated inside the sleeve plate. The rotating screw exerts a thrust on the sleeve, causing the pre-tightening plate to slide and press into the positioning block inside the sleeve plate. At the same time, after the screw stops rotating, the sleeve and screw can lock themselves, which is convenient for installation and disassembly and facilitates later maintenance.

[0019] This application provides a sludge discharge valve well, which effectively solves the problems of frequent operation and very low sludge discharge efficiency when sludge is discharged by gravity to the oxidation ditch sludge pumping station, and then transferred to the sludge desulfurization and thickening tank. The frequent entry and exit of the valve well poses safety hazards. The sludge discharge system is composed of a well body, a conveying pipe and a sludge discharge pump. The well body is used to hold sludge, and the conveying pipe connects the well body and the sludge discharge pump to realize sludge transportation. A timer switch is set on the side of the sludge discharge pump. The pumping is started after the side ditch has settled for one hour. It can operate in both directions, shorten the sludge discharge distance and improve the sludge discharge efficiency.

[0020] Example

[0021] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that sludge is discharged to the oxidation ditch sludge pumping station by gravity, and then transferred to the sludge desulfurization and thickening tank after transfer in the oxidation ditch sludge pumping station. During the sludge discharge process, frequent operation is required, the sludge discharge efficiency is very low, and the frequent entry and exit of valve wells poses a safety hazard. The overall idea is as follows:

[0022] To address the problems existing in the prior art, this utility model provides a mud discharge valve well, including a well body 11, a conveying pipe 12 and a mud discharge pump 13. One end of the conveying pipe 12 is connected to the well body 11, and the other end of the conveying pipe 12 is connected to the mud discharge pump 13.

[0023] By modifying the existing sludge discharge pipeline, a conveying pipe 12 and a sludge discharge pump 13 are installed on the side of the well body 11, so as to realize the connection with the oxidation ditch sludge discharge system and the bidirectional operation. A timer switch is set on the side of the sludge discharge pump 13, and the sludge is pumped out one hour after the side ditch settles, which improves the sludge discharge efficiency and can shorten the sludge discharge distance.

[0024] The surface of the conveying pipe 12 is provided with two clamps 14, and a sealing assembly is fixedly installed on the inner side of each clamp 14. Each sealing assembly includes a rubber strip 16 and a flange gasket 17.

[0025] By moving the two clamps 14, the clamps 14 are symmetrically clamped at the connection of the delivery pipe 12, connecting the interface of the delivery pipe 12 and the well body 11. Rubber strips 16 and flange gaskets 17 are installed on the inner side of the two clamps 14. The rubber strips 16 and flange gaskets 17 are squeezed and pressed tightly against the interface of the delivery pipe 12 to increase the sealing performance.

[0026] Each clamp 14 is fixedly installed with a positioning block 15 at its top end, and the side end of the positioning block 15 is provided with a positioning groove.

[0027] The inner wall of the positioning groove is designed with a slope. By moving the pre-tightening plate 19, the top of the pre-tightening plate 19 is inserted into the interior of the positioning block 15. Because the inner wall of the positioning groove is designed with a slope, the squeezing friction generates friction on the positioning block 15, which can tighten the two clamps 14.

[0028] Each clamp 14 is fixedly installed with a sleeve plate 18 on its outer side. Each sleeve plate 18 is slidably installed with a pre-tightening plate 19 inside. The top of each pre-tightening plate 19 has a conical protrusion structure. The positioning block 15 is inserted into the sleeve plate 18. First, the top of the pre-tightening plate 19 is squeezed, allowing the pre-tightening plate 19 to slide into the sleeve plate 18. The pre-tightening plate 19 squeezes the top of the reset rod 21, forcing the reset rod 21 to compress inside the sleeve plate 18. Two reset rods 21 are fixedly installed on the side end of each pre-tightening plate 19.

[0029] Each pretension plate 19 has a sleeve 22 fixedly installed on its side end. At the same time, the reset rod 21 generates a reverse force, causing the reset rod 21 to push the pretension plate 19 into the interior of the positioning block 15, thereby positioning the clamp 14 for easy operation.

[0030] Each sleeve plate 18 has a screw 23 rotatably mounted on its side end, which is connected to the sleeve 22. Each screw 23 has a thread that penetrates the inside of the sleeve plate 18. The thread helix angle of each screw 23 and the sleeve 22 is less than the friction angle. When the screw 23 is rotated, the screw 23 rotates inside the sleeve plate 18, and the end of the screw 23 rotates inside the sleeve 22.

[0031] The rotating screw 23 exerts a thrust on the sleeve 22, causing the preload plate 19 to slide and press against the positioning block 15 inside the sleeve plate 18. At the same time, after the screw 23 stops rotating, the sleeve 22 and the screw 23 can lock themselves.

[0032] The surface of the conveying pipe 12 is provided with an outwardly expanding convex ring structure, and the inner side of the clamp 14 is provided with a groove, and the inner side of the clamp 14 is engaged with the connecting end of the conveying pipe 12.

[0033] The connection end of the delivery pipe 12 is sealed and fixed by the clamp 14.

[0034] Working principle:

[0035] First, when it is necessary to connect the delivery pipe 12 and the well body 11, first put the two clamps 14 on the vicinity of the part of the delivery pipe 12 to be connected. At this time, the rubber strip 16 and flange gasket 17 on the inner side of the clamp 14 are in an uncompressed state. Align the interface of the delivery pipe 12 and the well body 11, and move the two clamps 14 so that they are symmetrically distributed on both sides of the connection of the delivery pipe 12. At this time, the groove on the inner side of the clamp 14 is initially aligned with the convex ring structure on the surface of the delivery pipe 12. The clamp 14 is initially locked at the connection end of the delivery pipe 12. The top of the positioning block 15 is inserted into the sleeve plate 18. Since the top of the pre-tightening plate 19 has a conical convex structure, the positioning block 15 squeezes the top of the pre-tightening plate 19, causing it to slide into the sleeve plate 18. The pre-tightening plate 19 squeezes the top of the reset rod 21. The reset rod 21 is compressed inside the sleeve plate 18. At the same time, the reset rod 21 generates a reverse force, pushing the pre-tightening plate 19 into the positioning block 15, thus completing the initial positioning of the clamp 14.

[0036] The second step involves rotating the screw 23. The screw 23 rotates inside the sleeve 18, with its end rotating inside the sleeve 22. Because the thread helix angle of the screw 23 and sleeve 22 is less than the friction angle, the rotating screw 23 generates a thrust on the sleeve 22, causing the pre-tightening plate 19 to slide and press against the positioning block 15 within the sleeve 18. Since the inner wall of the positioning groove of the positioning block 15 is designed with a slope, the pre-tightening plate 19 generates pressure and friction against the inner wall of the positioning groove when inserted, creating friction on the positioning block 15. This causes the clamps 14 to tighten. As the two clamps 14 tighten continuously, the rubber strips on the inner side of the clamps 14... 16 and flange gasket 17 are compressed and pressed tightly against the interface between the conveying pipe 12 and the well body 11, filling the gap and increasing the sealing performance, thus completing the sealing and fixing of the interface between the conveying pipe 12 and the well body 11. The sludge discharge valve well is modified based on the original sludge discharge pipeline. The well body 11, the conveying pipe 12 and the sludge discharge pump 13 constitute the sludge discharge system. The well body 11 is used to contain sludge. The conveying pipe 12 connects the well body 11 and the sludge discharge pump 13 to realize sludge transportation. A timer switch is set on the side of the sludge discharge pump 13. The pumping is started after the side ditch has settled for one hour. It can run in both directions, shortening the sludge discharge distance and improving the sludge discharge efficiency.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
