Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a high-efficiency and large-capacity sewage purification device. Background Art

[0002] High turbidity sewage refers to sewage containing a large amount of suspended solid particles, most of which are inorganic matter, and also contain some organic matter and microorganisms.

[0003] The purification device used in the prior art for purifying high turbidity sewage includes a water inlet pipe, a treatment agent pipe, a tubular mixer, a tank body, and a water outlet pipe. The sewage and the agent are mixed in the tubular mixer and then added to the tank body for further treatment.

[0004] However, in the above-mentioned prior art, a tubular mixer is used to mix sewage and chemicals, which easily causes flocculation and precipitation in the mixed sewage, blocking the tubular mixer and making it difficult to clean. Moreover, after the sewage enters the purification device, there is insufficient contact between the sewage, chemicals and flocculation crystallization nuclei, thereby reducing the efficiency of sewage purification. Utility Model Content

[0005] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a high-efficiency, large-capacity, high-turbidity sewage purification device which is easy to clean and not prone to clogging.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0007] A high-efficiency, large-capacity sewage purification device comprises a water inlet pipe, a drug inlet pipe, a tank body, a sewage discharge pipe and a water outlet pipe. The tank body is divided into a first filter zone, a second filter zone and a third filter zone from bottom to top. The water inlet pipe and the drug inlet pipe are connected to the first filter zone at the bottom of the tank body. The sewage discharge pipe extends from the bottom of the first filter zone. The water outlet pipe is installed on the side wall of the tank body above the third filter zone.

[0008] Furthermore, the first filter zone includes a mixing chamber, a mixing guide strip, a sludge concentration chamber, and a diverter baffle. The mixing chamber is located in the center of the first filter zone. The water inlet pipe and the drug inlet pipe enter the mixing chamber installed in the center of the first filter zone along the tangential direction. Porcelain balls are placed in the mixing chamber. The inner wall of the mixing chamber is provided with a spiral mixing guide strip. The top of the mixing chamber is a water outlet. The diverter baffle is installed above the water outlet of the mixing chamber through a bracket. The bottom of the diverter baffle is in an inverted cone shape and the top is a dome. The outer side of the mixing chamber and the inverted cone-shaped inner wall of the bottom of the tank form a sludge concentration chamber.

[0009] Furthermore, the second filtration zone includes a clarification chamber, a suspension chamber, a connecting layer, a mud scraper, a mud guard, and a motor. The clarification chamber is located in the center of the second filtration zone. The suspension chamber is between the outer side of the clarification chamber and the inner wall of the tank body. The bottom baffles of the clarification chamber and the suspension chamber are arranged in an inverted cone shape above the diversion baffle to form a connecting layer. The mud guard is installed at the opening above the clarification chamber. Filter holes are provided on the mud guard. The mud scraper is tangent to the bottom surface of the mud guard. A mud outlet is provided on the side wall of the clarification chamber below the mud guard. The motor is located at the top of the tank body, and the power output end of the motor is connected to the power input end above the mud scraper.

[0010] Furthermore, the third filter zone includes a filter baffle, a lightweight filter material, and a bypass pipe. The filter baffle is installed above the third filter zone, and the lightweight filter material floats below the filter baffle. The upper end of the bypass pipe is connected to the bottom of the lightweight filter material, and the lower end is connected to the sludge concentration chamber below the communication layer.

[0011] According to the above technical solution, the beneficial effect of the utility model is that: the utility model passes the water inlet pipe and the drug inlet pipe into the mixing chamber, and uses the spiral water flow to mix the drug and sewage evenly, effectively avoiding the problem of pipe blockage. At the same time, the porcelain balls placed in the mixing chamber can assist the full contact between the drug and the sewage, and when the water flow rises and the sludge precipitates, the full contact between the sewage and the flocculation crystallization nuclei is increased, thereby improving the overall working efficiency of the sewage purification device and enhancing the sewage purification effect.

DETAILED DESCRIPTION

[0015] In order to more clearly illustrate the technical solution implemented by the present invention, the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0016] See Figure 1-2, a high-efficiency and large-capacity sewage purification device, including a water inlet pipe 1, a drug inlet pipe 2, a tank body 3, a sewage pipe 4 and a water outlet pipe 5. The tank body 3 is divided into a first filter area 31, a second filter area 32, and a third filter area 33 from bottom to top. The water inlet pipe 1 and the drug inlet pipe 2 are connected to the first filter area 31 at the bottom of the tank body 3, and enter the mixing chamber 311 in the center of the first filter area 31 along the tangential direction. The sewage pipe 4 extends from the bottom surface of the first filter area 31, and the water outlet pipe 5 is installed on the side of the tank body 3 above the third filter area 33. The water inlet pipe 1 and the drug inlet pipe 2 respectively enter the first filter area 31, avoiding the problem of premature mixing of the drug and sewage, flocculation and precipitation in the pipeline, and blocking the pipeline, making the sewage purification device easy to clean and maintain.

[0017] See Figure 1-2 The first filter area 31 includes a mixing chamber 311, a mixing guide strip 312, a sludge concentration chamber 313, and a diversion baffle 314. The mixing chamber 311 is located in the center of the first filter area 31. The outer side of the mixing chamber 311 and the inverted conical inner wall of the bottom of the tank body 3 form a sludge concentration chamber 313. The inner wall of the mixing chamber 311 is provided with a spiral mixing guide strip 312. The mixing chamber 311 contains porcelain balls. The diversion baffle 314 is installed above the mixing chamber 311 through a bracket. The bottom of the diversion baffle 314 is The tank body 310 is in an inverted cone shape with a dome at the top. The reagent and sewage enter the mixing chamber 311 tangentially and are assisted by the mixing guide strip 312, so that the two fluids rise in a vortex and can be fully mixed. Ceramic balls are placed in the mixing chamber 311 to improve the contact efficiency between the reagent and the sewage, so that the sewage can quickly condense into sludge sediment after entering the sludge concentration chamber 313. The diversion baffle 314 evenly disperses the sewage overflowing the mixing chamber 311 into the sludge concentration chamber 313 to avoid uneven distribution of components in the tank body 3 affecting the sewage purification effect.

[0018] See Figure 1-2The second filtration area 32 includes a clarification chamber 321, a suspension chamber 322, a communication layer 323, a mud scraper 324, a mud guard 325, and a motor 326. The clarification chamber 321 is located in the center of the second filtration area 32. The suspension chamber 322 is between the outer side of the clarification chamber 321 and the inner wall of the tank body 3. The bottom baffles of the clarification chamber 321 and the suspension chamber 322 are inverted cones and are arranged above the diversion baffle 314 to form a communication layer 323. The mud guard 325 is installed at the opening above the clarification chamber 321. A filtering hole is provided on the mud guard 325. The scraper 324 is tangent to the bottom surface of the mud guard 325. The side wall of the clarification chamber 321 below the mud guard 325 is provided with an outlet. The mud outlet and the motor 326 are located at the top of the tank body 3. The power output end of the motor 326 is connected to the power input end above the sludge scraper 324. The sewage contacts the sludge falling from the connecting layer 323 during the rising process. The sludge is used as the crystal nucleus for flocculation precipitation, which can form flocculation precipitation faster. The light sludge in the remaining water rises through the clarification chamber 321 and is filtered and blocked by the mud guard 325 with an opening at the top. The sludge scraper 324 will evenly disperse the sludge filtered and intercepted by the mud guard 325 to the top of the suspension chamber 322 to form a sludge filtration layer. The heavier sludge particles fall through the surrounding suspension chamber 322, and contact with the sewage below after passing through the connecting layer 323, and are circulated, filtered and precipitated.

[0019] See Figure 1-2 The third filter zone 33 includes a filter baffle 331, a light filter material 332, and a bypass pipe 333. The filter baffle 331 is installed above the third filter zone, and the light filter material 332 floats below the filter baffle 331. The upper end of the bypass pipe 333 is connected to the bottom of the light filter material 332, and the lower end is connected to the sludge concentration chamber 313 below the communication layer 323. After passing through the sludge filtration layer, the water component continues to rise and is further adsorbed and filtered by the light filter material 332. The filter baffle 331 intercepts the light filter material 332 and impurities in the third filter zone 33. After overflowing the filter baffle 331, the clean water is discharged from the outlet pipe 5. The bypass pipe 333 below the light filter material 332 is connected to the sludge concentration chamber 313. The upper and lower pressure differences of the bypass pipe 333 are used to press the upper clean water in the sludge concentration chamber 313 into the third filter zone 33 above. The deposited sludge is compressed in the sludge concentration chamber 312 to achieve mud and water separation.

[0020] According to the above embodiment, the working process of the utility model is as follows:

[0021] Start the water pumps on the water inlet pipe 1 and the drug inlet pipe 2 to add materials to the mixing chamber 311. With the help of the porcelain balls in the mixing chamber 311, the sewage and the drug are fully contacted and mixed with each other, which saves the external tubular mixer and avoids the problem of pipeline blockage. After the sewage overflows the mixing chamber 311 and enters the sludge concentration chamber 312, it begins to flocculate and precipitate. The sludge with a larger specific gravity settles downward, and the sludge with a lighter specific gravity is suspended upward with the water flow. After the sewage enters the second filtering area 32, the sludge at the opening above the clarification area 321 is filtered and blocked by the mud guard 325 opened above. The sludge scraper 324 is evenly dispersed to the top of the suspension chamber 322 by the sludge filtered and intercepted by the mud guard 325 to form a suspended sludge layer. When the sewage water flows through the suspended sludge layer, the impurities in the water are adsorbed and filtered by the suspended sludge layer, and the sludge with increased specific gravity after adsorption sinks downward. The water in the sludge layer is continuously replenished with new light component sludge, and heavy component sludge is continuously deposited, forming a dynamic equilibrium adsorption filtration layer. The filtered water continues to rise and undergoes the final adsorption filtration in the third filter zone 33. The filter baffle 331 and the light filter material 332 further adsorb the remaining impurities in the water flow, thereby improving the sewage purification effect. The bypass pipe 333 is connected to the sludge concentration chamber 313. The upper and lower pressure differences of the bypass pipe 333 are used to press the upper clear water in the sludge concentration chamber 313 into the third filter zone 33 above. The deposited sludge is compressed in the sludge concentration chamber 312 to achieve mud-water separation. The clear water finally filtered through the third filter zone 33 is discharged from the sewage purification device through the upper outlet pipe 5.
