Description

Technical Field

[0001] The utility model relates to a sludge processing structure, in particular to a sludge discharge structure for a sedimentation tank. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is a water purification device that uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter from water.

[0003] After the sewage is precipitated in the sedimentation tank, the sludge contained in the sewage will settle at the bottom of the tank. After a certain amount of sludge is deposited at the bottom of the tank, the sludge needs to be discharged for the next use. Therefore, a sedimentation tank sludge discharge structure is needed.

[0004] The current sludge discharge structure of the sedimentation tank uses a sludge pump to extract the sludge, but the sludge accumulates a lot at the bottom of the tank and is large in volume. It is difficult to use the sludge pump to directly extract it, and the sludge pump is easily blocked, affecting the use of sludge discharge. Utility Model Content

[0005] The main purpose of the present disclosure is to provide a sedimentation tank sludge discharge structure to effectively solve the problems raised by the inventor in the above background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] A sedimentation tank sludge discharge structure includes a treatment tank, wherein outlet pipes are fixedly installed on the left and right sides near the upper end of the treatment tank, a scraper is slidingly provided near the lower end of the treatment tank, and the lower end of the scraper is in contact with the bottom of the treatment tank, a stirring tank is opened on the right side of the bottom of the treatment tank, and a plurality of stirring rods are provided in the stirring tank, a support plate is fixedly installed on the lower end of the right side of the treatment tank, and a sludge pump for pumping sludge is fixedly installed on the support plate.

[0008] Preferably, horizontal plates are fixedly installed on the front and rear sides of the treatment tank, a translation screw is rotatably installed in the front horizontal plate, and a slide rod is fixedly installed in the rear horizontal plate. One end of the two horizontal plates extends to the outside of the treatment tank, and sealing sleeves are fixedly installed at the connection between the two horizontal plates and the treatment tank. Openings are provided at the lower ends of the two horizontal plates. One end of the scraper is threaded on the translation screw, and the other end is slidably installed on the slide rod. The scraper can slide on the slide rod by rotating the translation screw, so that the scraper can translate the sludge at the bottom of the treatment tank and push it into the mixing tank for stirring and breaking it up.

[0009] Preferably, a servo motor is fixedly installed on the left side of the front horizontal plate, and the output end of the servo motor is fixedly connected to the rotating shaft of the translation screw, so that the servo motor can conveniently control the forward and reverse rotation of the translation screw for use.

[0010] Preferably, a stirring shaft is rotatably installed in the stirring tank, and multiple stirring rods are fixedly installed on the stirring shaft. A stirring motor is fixedly installed near the lower end of the front side of the treatment tank, and a transmission rod is fixedly installed at the output end of the stirring motor. The transmission rod is fixedly connected to the stirring shaft. The stirring motor drives the transmission rod to rotate the stirring shaft, thereby driving multiple stirring rods to rotate and stir and break up the sludge in the stirring tank, which can prevent the accumulation of a large amount of sludge that is difficult to be pumped out using a sludge pump.

[0011] Preferably, an extraction pipe is fixedly installed at the input end of the mud pump, a mud discharge pipe is fixedly installed at the output end, and an extraction cover is fixedly installed at the other end of the extraction pipe. The extraction cover extends into the stirring tank. When the mud pump is operated, the broken up sludge enters the extraction pipe through the extraction cover and is then discharged through the mud discharge pipe.

[0012] Preferably, baffle one is fixedly installed on both the front and rear inner sides of the treatment tank, the two baffle ones are respectively arranged on the upper ends of the two horizontal plates, and the two baffles one are arranged at an angle, and baffle two is fixedly installed on the right inner wall of the treatment tank, the baffle two is arranged above the stirring tank, and is arranged at an angle. The two baffles one can prevent sludge from falling on the two horizontal plates, while the baffle two can prevent the sludge in the stirring tank from splashing during the stirring process.

[0013] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0014] In this application, a stirring tank is set up, and when sludge needs to be discharged, the sludge at the bottom of the pool is pushed into the stirring tank through a scraper. The stirring motor drives the transmission rod to rotate the stirring shaft, thereby driving multiple stirring rods to rotate to stir and break up the sludge, and then the broken up sludge is pumped out by a sludge pump to prevent the accumulated sludge from being too large and difficult to be pumped out using a sludge pump.
