Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to a coagulation and decontamination type industrial sewage treatment device with a self-cleaning function. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely used in various industries and is of great significance. During the sewage treatment process, sedimentation tanks are required. By adding flocculants to the sewage in the sedimentation tank, the positively (negatively) charged groups of the flocculants and some particles or granules with negatively (positively) charged and difficult to separate in the water approach each other, reducing their electric potential, making them in an unstable state, and using their aggregation properties to concentrate these particles and separate them by physical or chemical methods.

[0003] After coagulation is completed, a sludge scraper is needed to clean the bottom of the sedimentation tank. However, during the coagulation process, the sludge scraper is often directly immersed in the sewage, and its surface is attached with flocculated sludge, which is very inconvenient to clean. It requires manual cleaning with a spray gun, and the side wall of the sedimentation tank cannot be cleaned thoroughly by the sludge scraper, resulting in a large demand for manual labor. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a coagulation and decontamination type industrial sewage treatment device with a self-cleaning function, which solves the problem that the existing sludge scraper needs manual assistance for cleaning after dredging.

[0006] (II) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A coagulation and decontamination type industrial sewage treatment device with a self-cleaning function includes a sedimentation tank. A lifting device is arranged outside the sedimentation tank. The output end of the lifting device is fixedly connected to a connecting frame. The upper surface of the connecting frame is fixedly connected to a support plate. The lower surface of the support plate is fixedly connected to a sliding rod. The outer surface of the sliding rod is fixedly connected to a lower fixed disk and an upper fixed disk. A water distribution tank is slidably connected between the lower fixed disk and the upper fixed disk;

[0008] A water pump, a water tank, and a motor are arranged on the upper surface of the water distribution tank. The output end of the motor is fixedly connected to a roller, and the roller rolls on the lower part of the connecting frame. The lower surface of the water distribution tank is fixedly connected to a water pipe rack. The left pipe of the water pipe rack is fixedly connected to a water spraying plate. The left side surface of the water spraying plate is fixedly connected to a side scraper. One row of bottom scrapers is fixedly connected to the side of the water pipe rack far from the water distribution tank;

[0009] The lower bottom surface of the sedimentation tank is provided with a silt suction head. The bottom of the sedimentation tank is fixedly connected with an outer cylinder. The side wall of the outer cylinder is provided with medicine spraying holes. A spring is fixedly connected to the bottom of the sedimentation tank and inside the outer cylinder. The upper end of the spring is fixedly connected with a hole blocking member. The lower end of the sliding rod is fixedly connected with a fixing rod, and a pushing plate is fixedly connected to the outer surface of the fixing rod.

[0010] The silt suction pump and the medicine tank are arranged on both sides of the lifting device. The medicine tank is connected to an air pump through a pipe.

[0011] Preferably, a fixing plate is fixedly connected to the right side surface of the water distribution tank. Ball bearings are arranged on the upper and lower side surfaces of the water distribution tank between the lower fixing plate and the upper fixing plate.

[0012] Preferably, both the ball bearings and the fixing plate are inside the lower fixing plate and the upper fixing plate. The fixing plate is rotatably connected to the outer surface of the sliding rod.

[0013] Preferably, the side surface of the side scraping plate away from the water spraying plate is in contact with the inner wall of the sedimentation tank. The left side surface of the water spraying plate is provided with a first water spraying port.

[0014] Preferably, the bottom scraping plates are parallel to each other, and are penetrated with second water spraying holes and are connected to the water pipe support through a communicating pipe.

[0015] Preferably, a sludge discharge hole penetrates through the bottom of the sedimentation tank. The sludge discharge hole is located outside the outer cylinder. The silt suction head and the silt suction pump are connected through a pipe.

[0016] Preferably, the medicine tank is communicated with the side wall of the outer cylinder below the hole blocking member through a pipe passing through the bottom of the sedimentation tank.

[0017] Preferably, both the hole blocking member and the sliding rod are slidably connected to the inner wall of the outer cylinder.

[0018] Working principle: After adding flocculant into the reagent tank, the air pump inflates the reagent tank, blows the flocculant into the outer cylinder through the pipeline. After the lifting device drives the connecting frame to descend, the connecting frame drives the sliding rod to move downward, and then the fixed rod drives the push plate to press down the orifice part, compressing the spring and opening the spraying holes. Under the action of the high-pressure gas inside the outer cylinder, the flocculant enters the sewage in the sedimentation tank from the spraying holes along with the high-pressure gas. The flocculant fully enters the sewage with the high-pressure gas. When the high-pressure gas rises, it drives the flocculant to move upward and diffuse. When the motor drives the roller to roll on the connecting frame, the water distribution tank rotates around the sliding rod from the fixed plate, driving the water pipe frame to rotate the spraying plate and the bottom scraper, and then acting on the sewage to accelerate the diffusion of the flocculant. The above process can also be applied to dredging. The water in the water tank is sent into the water distribution tank through the action of the water pump, and then flows through the water pipe frame and sprays water from the spraying plate and the bottom scraper. The water sprayed by the spraying plate acts on the inner wall of the sedimentation tank and the side scraper, so that the side scraper cleans the inner wall of the sedimentation tank and discharges the dirt. The scraped sludge falls to the bottom of the sedimentation tank and is scraped into the bottom of the sedimentation tank under the action of the bottom scraper. Under the action of the sludge suction pump, the suction head generates suction to suck the sludge at the bottom of the sedimentation tank outwards. The bottom scrapers spray water on each other to clean each other, and at the same time, the water falling to the bottom of the sedimentation tank can assist the bottom scraper to clean the bottom of the sedimentation tank.

[0019] (III) Beneficial effects

[0020] The present invention provides a coagulation and decontamination type industrial sewage treatment device with self-cleaning function, having the following beneficial effects:

[0021] 1. In the present invention, the rotating water distribution tank driven by the motor drives the water pipe frame to make the side scraper and the bottom scraper clean the sedimentation tank, which can clean all parts of the sedimentation tank. Spraying water from the spraying plate and the bottom scraper can clean the side scraper and the bottom scraper, and can also assist in cleaning the sedimentation tank. The sludge cleaned to the bottom of the sedimentation tank is sucked out from the suction head under the action of the sludge suction pump.

[0022] 2. In the present invention, the air pump blows the flocculant in the reagent tank into the outer cylinder. After the sliding rod is driven by the lifting device to move downward, the fixed rod drives the push plate to press down the orifice part, thereby opening the spraying holes and enabling the flocculant to fully enter the sewage along with the high-pressure air flow.

[0023] 3. In the present invention, the lifting device drives the connecting frame to move upward, and then the support plate drives the sliding rod to move upward, so that the water distribution tank drives the water pipe frame to move the bottom scraper and the side scraper upward, reducing the adhesion of sludge on their surfaces.
