Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to an air-lift sludge discharge device in an integrated sewage treatment equipment. Background Technique

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. In sewage treatment equipment, the first step is usually a sedimentation tank. In the sedimentation tank, a large amount of suspended substances and other impurities are settled, forming sludge at the bottom of the tank. The upper water body is then treated for reuse, and the sludge needs to be discharged for secondary treatment.

[0003] For example, the Chinese authorized patent with the publication number CN218774361U (sludge discharge device for integrated sewage treatment equipment): includes a sedimentation tank, equipment pipes, sludge discharge pipes, a lead screw motor, and a rotating shaft. A base block is fixed at the inner bottom of the sedimentation tank. Sludge storage tanks are arranged in the sedimentation tank on both sides of the base block. Equipment pipes are fixed at the lower two corners at one end of the sedimentation tank. A lead screw motor is fixed at the end of the equipment pipe away from the sedimentation tank. A first sludge pushing plate, a second sludge pushing plate, and a crushing cutter are sequentially arranged on the outer peripheral side of the rotating shaft. And one end of the rotating shaft close to the sedimentation tank is rotatably connected to an end plate, and a pushing cutter is fixed on the front side of the end plate. By setting the equipment pipes, rotating shaft, lead screw motor, sedimentation tank, base block, crushing cutter, and pushing cutter, the problems of low efficiency, high equipment energy consumption, incomplete sludge discharge when discharging the sludge at the bottom of the sedimentation tank, and the sludge at the bottom of the sedimentation tank being hard and stubborn and inconvenient to discharge are solved.

[0004] However, most of the sludge discharge methods in the existing integrated sewage treatment equipment use submersible pumps to suck sludge. After the equipment runs for a period of time, the equipment needs to be lifted out for maintenance, which is rather troublesome, and the power consumption cost and maintenance cost are relatively high. Therefore, it does not meet the existing requirements. For this reason, we propose an air-lift sludge discharge device in an integrated sewage treatment equipment. Content of the Utility Model

[0005] The purpose of the utility model is to provide an air-lift sludge discharge device in an integrated sewage treatment equipment to solve the problems in the background technique that most of the sludge discharge methods in the existing integrated sewage treatment equipment use submersible pumps to suck sludge. After the equipment runs for a period of time, the equipment needs to be lifted out for maintenance, which is rather troublesome, and the power consumption cost and maintenance cost are relatively high.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an air-lift sludge discharge device in an integrated sewage treatment equipment, including a treatment chamber, a sludge discharge pipe is arranged inside the treatment chamber, an air delivery pipe is arranged at the bottom below the sludge discharge pipe, the air delivery pipe is connected to the sludge discharge pipe through a tee, a union, and a reducing bushing, and a partition board is arranged at the pipeline above the air delivery pipe.

[0007] Further included are:

[0008] A baffle plate, which is arranged on one side of the air delivery pipe, and the air delivery pipe is connected to the baffle plate by welding. An electromagnetic valve and a manual ball valve are arranged on the air delivery pipe, and the electromagnetic valve and the manual ball valve are fixed on the air delivery pipe through a quick-thread coupling.

[0009] An air bag, which is arranged at the top end of the air delivery pipe, and the air bag is connected to the air delivery pipe by welding. The air bag is welded above the equipment top plate.

[0010] Preferably, an air inlet pipe is arranged below the air bag, and the air bag is connected to the air inlet pipe by welding.

[0011] Preferably, a check valve and a flexible connecting pipe are arranged below the air bag.

[0012] Preferably, the check valve and the flexible connecting pipe are fixed on the air inlet pipe through a quick-thread coupling.

[0013] Preferably, a vortex blower is arranged at one end of the bottom of the air inlet pipe, and the vortex blower is connected to the air inlet pipe through a threaded joint.

[0014] Preferably, a mounting seat is arranged at the bottom of the vortex blower, and the vortex blower is fixedly connected to the mounting seat by screws.

[0015] Preferably, a sludge discharge port is arranged on one side of the top end of the sludge discharge pipe, and a connecting plate is arranged on the sludge discharge port.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. The present utility model forms a sludge discharge assembly by the sludge discharge pipe, the air delivery pipe, the tee pipe, the electromagnetic valve, and the manual ball valve. The air delivery pipe is fixed on the baffle plate by welding, and the remaining pipe fittings and valves are fixed on the wall panel by pipe clamps. The air bag, the air inlet pipe, the check valve, the flexible connecting pipe, and the vortex blower form an air source assembly. The air bag is fixed on the equipment top plate by welding, the pipe fittings are connected through threaded joints, and the vortex blower is fixed on the mounting seat by bolts. During operation, the vortex blower is started to deliver air into the air bag. When the air bag reaches a certain pressure, the blower stops working. When sludge discharge is required, the electromagnetic valve on the air delivery pipe is opened, and the gas in the air bag enters the sludge discharge pipe through the air delivery pipe. After the gas enters the sludge discharge pipe, the sludge at the bottom inside the treatment chamber is taken out of the chamber through the sludge discharge port, thereby realizing the function of sludge discharge, and solving the problem that most of the sludge discharge methods in the prior art integrated sewage treatment equipment use a submersible pump to suck sludge. After the equipment operates for a period of time, the equipment needs to be hoisted out for maintenance, which is rather troublesome, and the power consumption cost and the maintenance cost are both relatively high.

[0018] 2. By setting a check valve, the gas in the air bag cannot return to the fan, thus protecting the fan. A sludge discharge port is provided on one side of the top end of the sludge discharge pipe. The sludge discharge pipe is installed and fixed through the connection plate of the sludge discharge port, which facilitates its disassembly and assembly. Description of the Drawings
