Description

Mud discharging valve well Technical Field The utility model relates to the technical field of sewage treatment, in particular to a mud discharging valve well. Background The valve well can provide a relatively stable and safe environment for the sludge discharge valve, avoids the valve from being directly influenced by external factors such as rainwater, sundries, mechanical collision and the like, prolongs the service life of the valve, and mainly utilizes the non-uniformity of dissolved oxygen distribution in the ditch to enable the ditch to generate an aerobic zone and an anoxic zone which circulate alternately through reasonable design so as to achieve the aim of denitrification. In conventional three-channel oxidation channels, microorganisms in short, frequent environmental changes of aerobic-anoxic-aerobic conditions cause nitrifying bacteria and denitrifying bacteria to be not always in an optimal growth metabolism environment, thereby also affecting the throughput of structures per unit volume. The oxidation ditch sludge discharge is manually controlled by valves in four valve wells at the water outlet end, sludge is discharged to an oxidation ditch sludge pump room through gravity, and is discharged to a sewage stripping concentration tank after being transferred by the oxidation ditch sludge pump room, so that in the sludge discharge process, frequent operation is needed, the sludge discharge efficiency is very low, potential safety hazards exist when the sludge is frequently fed into and discharged from the valve wells, the safety is insufficient, and the sludge discharge is to be improved. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a sludge discharge valve well, which solves the technical problems that the sludge is discharged to an oxidation ditch sludge pump room by gravity, is transferred from the oxidation ditch sludge pump room and then is discharged to a sewage concentrating pool, frequent operation is needed in the sludge discharge process, the sludge discharge efficiency is very low, and potential safety hazards exist in the process of frequently entering and exiting the valve well. In order to achieve the above purpose, the utility model is realized by the following technical scheme: the mud discharging valve well comprises a well body, a conveying pipe and a mud discharging pump, wherein one end of the conveying pipe is connected with the well body in a penetrating way, and the other end of the conveying pipe is connected with the mud discharging pump; The surface of conveyer pipe is provided with two clamps, every the inboard of clamp is all fixed mounting has seal assembly, every seal assembly all includes adhesive tape and flange gasket. Preferably, the top end of each clamp is fixedly provided with a positioning block, the side end of each positioning block is provided with a positioning groove, the outer side of each clamp is fixedly provided with a sleeve plate, the inside of each sleeve plate is slidably provided with a pre-tightening plate, and the top end of each pre-tightening plate is of a conical protruding structure. Preferably, two reset rods are fixedly arranged at the side end parts of each pre-tightening plate, a sleeve is fixedly arranged at the side end part of each pre-tightening plate, a screw rod butted with the sleeve is rotatably arranged at the side end part of each sleeve, threads of each screw rod penetrate through the sleeve, the thread rise angle of each screw rod and the sleeve is smaller than the friction angle, and an outward-expanding convex ring structure is arranged on the surface of the conveying pipe. Compared with the prior art, the utility model has the following beneficial effects; the sludge discharge system is formed by a well body, a conveying pipe and a sludge discharge pump, wherein the well body is used for accommodating sludge, the conveying pipe is connected with the well body and the sludge discharge pump to realize sludge conveying, a timing switch is arranged at the side end of the sludge discharge pump, sludge is started after a side ditch is settled for one hour, the sludge discharge system can run bidirectionally, the sludge discharge distance is shortened, and the sludge discharge efficiency is improved; the reset rod is used for pushing the pre-tightening plate to be inserted into the positioning block, the clamp is positioned firstly, the screw rod is rotated in the sleeve plate, the rotating screw rod generates thrust to the sleeve, the pre-tightening plate slides and extrudes in the sleeve plate to the inside of the positioning block, and meanwhile, after the screw rod stops rotating, the sleeve and the screw rod can be locked automatically, so that the clamp is convenient to install and detach, and later maintenance is facilitated.
