Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater sedimentation tank that is easy to clean. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. The wastewater treatment process requires the use of sedimentation tanks for sedimentation treatment. Sedimentation tanks are structures that use sedimentation to remove suspended solids in water. Some special types of wastewater also require the addition of flocculants during sedimentation treatment.

[0003] During the use of sedimentation tanks, impurities in the water are released after sedimentation, and sludge and impurities will naturally accumulate at the bottom of the sedimentation tank. In order to ensure the normal use of the sedimentation tank, it is necessary to clean the sludge at the bottom of the sedimentation tank. However, the existing sedimentation tank spraying and cleaning work are basically two separate sets of equipment, which is not only costly, but also occupies a lot of space. Existing cleaning equipment usually uses screw conveyors to extract and transfer sludge. However, the sludge at the bottom that is in contact with the screw becomes extremely viscous after long-term sedimentation, clogging the screw conveyor blades and affecting the efficiency of subsequent work, which has room for further improvement. Utility Model Content

An electric screw is installed inside the sewage discharge trough, and a sliding baffle is slidably connected to the inner side of the upper part of the sewage discharge trough. Side toothed rails are fixedly connected to both sides of the upper part of the sedimentation tank body, and a gantry frame is slidably installed on the upper part of the sedimentation tank body through the two side toothed rails. Drive seats are provided on both sides of the lower part of the gantry frame at positions corresponding to the side toothed rails, and drive motors are fixedly connected to the outer sides of the upper part of the two drive seats.

[0006] A spraying base is fixedly connected to the lower part of one side of the top of the gantry frame. Multiple spraying nozzles are provided in the middle of the lower part of the spraying base. Two high-pressure nozzles are provided at both ends of the lower part of the spraying base. A diaphragm pump is fixedly connected to the upper part of one end of the spraying base. A mixing tank is fixedly connected to the upper part of the spraying base near the diaphragm pump.

[0007] Both ends of the gantry frame away from the spraying base are slidably connected to lifting slides. An electric lifting rod is provided in the middle of each of the two lifting slides. A turning shovel is fixedly connected to the bottom lifting end of each of the two electric lifting rods.

[0008] According to the aforementioned easy-to-clean sewage sedimentation tank, drive gears are provided on the inner sides of the two drive seats at positions corresponding to the side toothed rails, and the output ends of the two drive motors are connected to the side toothed rails via the drive gears.

[0009] According to the aforementioned easy-to-clean sewage sedimentation tank, a closable discharge port is provided on the outside of the main body of the sedimentation tank below the power end of the electric screw, and a sludge conveyor belt is provided below the discharge port.

[0010] According to the aforementioned easy-to-clean sewage sedimentation tank, an electric winch connected to a sliding baffle is provided on the exterior of the sedimentation tank body at the end away from the sludge conveyor belt, and a hook plate is provided on the end of the sliding baffle away from the electric winch.

[0011] According to the aforementioned sewage sedimentation tank that is easy to clean, the turning shovels on the same side of the V-shaped tank bottom are all provided with the same inclination angle as the V-shaped tank bottom.

[0012] According to the aforementioned easy-to-clean sewage sedimentation tank, the gantry frame is internally equipped with a bidirectional lead screw that cooperates with two lifting slides. A lead screw motor is installed in the upper center of the gantry frame, and the output end of the lead screw motor is connected to the bidirectional lead screw drive through a worm gear structure.

[0013] According to the aforementioned easy-to-clean sewage sedimentation tank, an electric agitator is installed inside the mixing tank, and the mixing tank is connected to a diaphragm pump via an electrically controlled flow valve.

[0014] According to the aforementioned easy-to-clean sewage sedimentation tank, the output end of the diaphragm pump is connected to multiple spray nozzles and four high-pressure nozzles respectively through two mutually exclusive solenoid valves.

[0015] The above solution has at least one of the following beneficial effects:

[0016] 1. This utility model is equipped with a V-shaped pool bottom and a sludge discharge trough. With the help of an electric screw and a sliding baffle, most of the sludge can be blocked by the sliding baffle during sedimentation, preventing the sludge from directly contacting the electric screw and avoiding sludge from clogging the screw blades.

[0017] 2. The spraying base of this utility model is equipped with a spray nozzle and a high-pressure nozzle. In conjunction with a diaphragm pump, it can spray medicine through the spray nozzle during sedimentation. During cleaning, since the number of spray nozzles is much greater than the number of high-pressure nozzles, the high-pressure nozzles can spray high-pressure water jets by simply switching the passage through a valve, which helps to clean the sludge and enhances the practicality of the device.

[0018] 3. This utility model is equipped with a gantry frame and a lifting slide, which, together with an electric lifting rod and a turning shovel, can agitate the sewage during mobile spraying to improve diffusion efficiency.

During cleaning, the sliding baffle 17 can be gradually pulled out to control the amount of sludge falling, which can greatly reduce the starting pressure of the electric screw 16.
