Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to an intelligent partition sewage treatment tank. Background Art

[0002] The SBR sewage treatment process is a commonly used sewage treatment process. By continuously aerating the sewage, the growth environment of microorganisms in the sewage is changed, so as to accelerate the decomposition of pollutants such as organic matter, ammonia, and nitrogen in the sewage by microorganisms. When the sewage in the sewage treatment tank meets the discharge requirements, the aeration pipeline stops aerating and stands still for a period of time. The sludge gradually settles at the bottom. At this time, the supernatant located in the upper layer needs to be discharged. Currently, a water decanter is used to take water on the water surface layer to avoid disturbing the sludge in the lower layer.

[0003] However, during the aeration process of sewage, a large number of bubbles generated by aeration will carry some impurities such as grease and fibers and float on the water surface, gradually forming a layer of scum at the sewage water surface, and there are also some biological flocs formed by the fragmentation and deflocculation of old sludge suspended in the water and not easy to sink. When using the water decanter to drain water, suspended matter impurities and some scum will be discharged with the water, affecting the effluent quality. If a filter screen is set at the water inlet of the water decanter, under the drive of the water flow, the impurities will continuously adhere to the surface of the filter screen, so that after filtering for a period of time, more impurities will accumulate on the surface of the filter screen, seriously affecting the smoothness of the clear liquid passing through the filter screen, resulting in a decrease in the drainage speed, and even may cause the filter screen to be blocked. Summary of the Invention

[0004] In order to overcome the disadvantages that when the water decanter of the existing sewage treatment tank drains water, suspended matter impurities and some scum will be discharged with the water, affecting the effluent quality, and if a filter screen is set at the water inlet, under the drive of the water flow, the impurities will continuously adhere to the surface of the filter screen, seriously affecting the smoothness of the clear liquid passing through the filter screen, the present invention provides an intelligent partition sewage treatment tank.

[0005] The technical implementation solution of the present invention is: an intelligent partition sewage treatment tank, including a sewage treatment tank, an electric guide rail, a connecting frame and a housing; a pre-storage area is arranged in the sewage treatment tank; a reaction area is arranged in the sewage treatment tank, and an aeration pipeline is arranged at the bottom of the reaction area; two electric guide rails are fixedly connected to the reaction area; a connecting frame is slidably connected between the electric guide rails; a housing is fixedly connected to the connecting frame; it also includes a baffle, a second filter screen, a drainage branch pipe, a drain pipe and a slag discharge pipe; a water inlet is opened on the right side of the housing; a partition plate is fixedly connected in the housing; the right side of the housing is connected with a baffle through an electric slider, and the baffle is slidably connected to the inner wall of the housing in a sealed manner; a through hole is opened on the baffle, and a first filter screen is arranged on the lower side of the through hole; the left side of the baffle is rotatably connected with a second filter screen; the other side of the second filter screen is rotatably connected to the housing; a plurality of drainage branch pipes for draining water are communicated with the housing, and the drainage branch pipes are made of deformable materials; all the drainage branch pipes are jointly communicated with a drain pipe; a slag discharge pipe for discharging impurities is communicated with the housing; the pipe orifice of the drainage branch pipe is located on the right side of the pipe orifice of the slag discharge pipe, and the partition plate is located between the pipe orifice of the drainage branch pipe and the pipe orifice of the slag discharge pipe.

[0006] In addition, particularly preferably, a capacitive liquid level sensor is arranged on the right side of the baffle, the capacitive liquid level sensor is located above the through hole, and a vertical groove for avoiding the up and down movement of the capacitive liquid level sensor is opened at the corresponding position on the housing.

[0007] In addition, particularly preferably, it further includes a scraping blade; a scraping blade is fixedly connected to the right side of the housing, the scraping blade is located below the water inlet, and the scraping blade is in close contact with the first filter screen.

[0008] In addition, particularly preferably, two slide rails are arranged on the second filter screen; a scraping plate is slidably connected between the slide rails.

[0009] In addition, particularly preferably, the scraping plate is L-shaped.

[0010] In addition, particularly preferably, the scraping plate is made of high-density metal material.

[0011] In addition, particularly preferably, a first guiding inclined surface inclined downward toward the pipe orifice of the slag discharge pipe is arranged on the lower side inside the housing; the first guiding inclined surface is located on the left side of the partition plate.

[0012] In addition, particularly preferably, a second guiding inclined surface inclined from the lower left side to the upper right side is arranged at the bottom of the housing.

[0013] In addition, particularly preferably, both the drainage branch pipe and the slag discharge pipe are arranged in an inclined manner from the upper left side to the lower right side.

[0014] In addition, particularly preferably, it further includes an electric rotating shaft; an electric rotating shaft is connected to the inside of the housing through a fixing plate, the electric rotating shaft is located above the pipe orifice of the slag discharge pipe, and a plurality of cutting blades are fixedly connected to the lower side of the electric rotating shaft.

[0015] Beneficial effects: The present invention realizes that the water inlet is immersed in water, and the clear liquid sequentially passes through the water inlet, the through port and the second filter screen, and finally is discharged through the drain branch pipe and the drain pipe. The second filter screen intercepts suspended impurities to ensure the quality of the clear liquid. The connecting frame and the housing move downward at a constant speed, continuously draw water from the surface layer of the water surface, avoid disturbing the lower sludge, and can intercept the suspended impurities in the clear liquid through the second filter screen to prevent the suspended impurities from mixing into the clear liquid and being discharged together, thus affecting the water quality of the clear liquid;

[0016] When the second filter screen is blocked and the drainage speed decreases, while the downward movement speed of the housing remains unchanged, resulting in the water surface rising relative to the housing. When the water surface rises to the point where the capacitive liquid level sensor is detected, it can be known that the through port has been completely immersed in water. When the second filter screen is blocked and the drainage speed decreases, the capacitive liquid level sensor detects the rising water level, controls the electric slider to drive the baffle to move upward, aligns the first filter screen with the water inlet, and the second filter screen tilts. The scraper made of high-density material slides along the slide rail, scrapes the suspended impurities to the first guiding slope, and intercepts the impurities through the first filter screen to ensure smooth drainage;

[0017] Before draining water, first move the baffle upward to block the water inlet, rotate the second filter screen to tilt towards the lower left side, and the housing and its connected parts move downward, so that the baffle is completely immersed in water. The water flow carries the scum over the baffle and drops onto the second filter screen. Then the scum is intercepted by the second filter screen, and most of the clear liquid passes through the second filter screen and is discharged through the drain branch pipe and the drain pipe. A small part of the clear liquid fails to pass through the second filter screen in time and flows along the second filter screen tilted towards the lower left side onto the first guiding slope. Thus, this part of the water flow can drive the scum on the second filter screen to flow to the first guiding slope in time, thereby realizing the pre-discharge of the scum on the water surface and effectively reducing the subsequent filtering burden of the second filter screen;

[0018] When the housing moves downward until its bottom is lower than the drain pipe, the clear liquid flowing into the housing cannot be discharged through the drain branch pipe from the drain pipe, causing the clear liquid to continuously accumulate in the housing until it flows over the partition and onto the first guiding slope. Thus, the water flow carries the scum and suspended impurities on the first guiding slope into the slag discharge pipe, preventing the scum and suspended impurities from continuously accumulating on the first guiding slope, and cleaning the inside of the housing through the clear liquid, so there is no need to additionally set a cleaning pipeline in the housing.

[0031] Embodiment 1

[0032] An intelligent partitioned sewage treatment tank, such as Figures 1-9As shown in the figure, it includes a sewage treatment tank 1, an electric guide rail 2, a connecting frame 3 and a housing 4; on the right side inside the sewage treatment tank 1, there is a pre-storage area 1001; on the left side inside the sewage treatment tank 1, there is a reaction area 1002, and an aeration pipeline is arranged at the bottom of the reaction area 1002; a water inlet pipe is communicated with the side wall of the pre-storage area 1001, and a communication pipeline is arranged between the pre-storage area 1001 and the reaction area 1002; on the left side of the reaction area 1002, two electric guide rails 2 arranged symmetrically front and back are fixedly connected; all the electric guide rails 2 are jointly slidably connected with a connecting frame 3; a housing 4 is fixedly connected to the lower side of the connecting frame 3;

[0033] It also includes a baffle 5, a second filter screen 6, a drainage branch pipe 101, a drainage pipe 102 and a slag discharge pipe 201; an inlet 4001 is opened on the right side of the housing 4; a partition 4002 is fixedly connected inside the housing 4; the right side of the housing 4 is connected with an up-and-down moving baffle 5 through an electric slider, and the baffle 5 is slidably connected to the inner wall of the housing 4 in a sealed manner to prevent sewage from directly seeping into the housing 4 between the baffle 5 and the housing 4; a through hole 5001 is opened on the baffle 5, and a first filter screen 5002 is arranged below the through hole 5001. Initially, the through hole 5001 is aligned with the inlet 4001; a second filter screen 6 is rotatably connected to the left side of the baffle 5, and the connection part between the baffle 5 and the second filter screen 6 is located between the through hole 5001 and the first filter screen 5002; the other side of the second filter screen 6 is rotatably connected to the housing 4; three drainage branch pipes 101 are communicated with the lower side of the housing 4, and the drainage branch pipes 101 are made of deformable materials; all the drainage branch pipes 101 are jointly communicated with a drainage pipe 102; a slag discharge pipe 201 is communicated with the lower side of the housing 4; the pipe orifice of the drainage branch pipe 101 is located on the right side of the pipe orifice of the slag discharge pipe 201, and the partition 4002 is located between the pipe orifice of the drainage branch pipe 101 and the pipe orifice of the slag discharge pipe 201.

[0034] A capacitive liquid level sensor 5003 is arranged on the right side of the baffle 5. The capacitive liquid level sensor 5003 is located above the through hole 5001, and a vertical groove for avoiding the up-and-down movement of the capacitive liquid level sensor 5003 is opened at the corresponding position on the housing 4.

[0035] It also includes a scraping blade 301; a scraping blade 301 is fixedly connected to the right side of the housing 4. The scraping blade 301 is located below the inlet 4001, and the scraping blade 301 is in close contact with the first filter screen 5002.

[0036] Two slide rails 6001 arranged symmetrically front and back are arranged on the second filter screen 6; all the slide rails 6001 are jointly slidably connected with a scraping plate 6002.

[0037] The scraping plate 6002 is L-shaped to prevent impurities from passing over the scraping plate 6002 when scraping impurities.

[0038] The scraping plate 6002 is made of high-density metal material.

[0039] A first guiding slope 4003 inclined downward toward the nozzle side of the slag discharge pipe 201 is provided on the lower side inside the housing 4; the first guiding slope 4003 is located on the left side of the partition 4002.

[0040] A second guiding slope 4004 inclined from the lower left side to the upper right side is provided at the bottom of the housing 4.

[0041] Both the drain branch pipe 101 and the slag discharge pipe 201 are inclined from the upper left side to the lower right side, so as to prevent the drain branch pipe 101 and the slag discharge pipe 201 from accumulating at the side wall of the reaction zone 1002 and affecting the sludge flow.

[0042] During operation, sewage is gradually injected into the pre-storage area 1001 through the water inlet pipe. After the pre-storage area 1001 is filled with sewage, a chemical agent is added to pre-treat the sewage. Then, the pre-treated sewage in the pre-storage area 1001 is discharged into the reaction zone 1002 through the connecting pipe between the pre-storage area 1001 and the reaction zone 1002. Then, the aeration pipe in the reaction zone 1002 is started to aerate the sewage, so as to promote the rapid reproduction of activated sludge microorganisms in the sewage and decompose the pollutants in the sewage. By treating the sewage in different zones, large particulate suspensions are first precipitated in the pre-storage area 1001, and the heavy metals and toxic substances in the sewage are diluted or neutralized by adding chemical agents, effectively reducing the sludge load in the subsequent reaction zone 1002 and protecting the microbial activity. The reaction zone 1002 is dedicated to aeration to promote the rapid proliferation of activated sludge microorganisms and ensure the pollutant degradation rate, thereby effectively ensuring the sewage treatment effect. Then, when the sewage in the reaction zone 1002 meets the discharge requirements, the aeration pipe stops aerating and stands for a period of time. The sludge gradually settles at the bottom of the reaction zone 1002. To treat the next batch of sewage, the supernatant located in the upper layer needs to be discharged. By controlling the electric guide rail 2 to drive the connecting frame 3, the housing 4 and the connected parts thereof to move downward, the water inlet 4001 is immersed in the water. Then, the supernatant can sequentially pass through the water inlet 4001 and the through hole 5001, and then pass through the second filter screen 6, fall below the second filter screen 6, and flow through the drain branch pipe 101 and the drain pipe 102 to be discharged outward. Thus, as the electric guide rail 2 drives the connecting frame 3, the housing 4 and the connected parts thereof to move downward at a constant speed, the supernatant in the upper layer is gradually discharged, and water is always taken from the water surface layer, without disturbing the sludge in the lower layer, and the suspended matter impurities in the supernatant can be intercepted by the second filter screen 6 to prevent the suspended matter impurities from being mixed into the supernatant and discharged together, which affects the water quality of the supernatant.

[0043] Due to the continuous adhesion of suspended impurities to the surface of the second filter screen 6 driven by the water flow, after a period of filtration, a large amount of suspended impurities accumulate on the surface of the second filter screen 6, seriously affecting the smoothness of the clear liquid passing through the second filter screen 6, which will lead to a decrease in the drainage speed. Since the downward movement speed of the housing 4 remains unchanged, the water surface moves upward relative to the housing 4. When the water level rises and triggers the capacitive liquid level sensor 5003, it can be known that the through port 5001 has been completely submerged in water. As Figure 9 shown, by controlling the electric slider to drive the baffle 5 to slide upward, the first filter screen 5002 is aligned with the water inlet 4001, and the baffle 5 drives the second filter screen 6 to rotate to be inclined towards the lower left side. Since the scraper 6002 is made of high-density metal material, under the action of gravity, the scraper 6002 slides along the slide rail 6001 towards the lower left side. The scraper 6002 scrapes off the suspended impurities on the second filter screen 6, causing the suspended impurities to fall onto the first guiding inclined surface 4003. Moreover, the scraper 6002 is L-shaped, so when scraping the impurities, it prevents the impurities from passing over the scraper 6002, and the partition plate 4002 separates the impurities from the clear liquid. In this state, after the clear liquid passes through the water inlet 4001 and the first filter screen 5002, it is drained away through the drainage branch pipe 101 and the drainage pipe 102. Thus, the suspended impurities can be intercepted by the unblocked first filter screen 5002, ensuring normal drainage while quickly transferring the suspended impurities on the second filter screen 6. When all the suspended impurities on the second filter screen 6 are scraped off onto the first guiding inclined surface 4003, the electric slider can be controlled to drive the baffle 5 to reset downward.

[0044] It should be noted that when the baffle 5 resets downward, the scraping blade 301 can be used to scrape off the suspended impurities on the first filter screen 5002 to ensure the normal passage of the subsequent clear liquid through the first filter screen 5002.

[0045] However, in the process of aerating the sewage, a large number of bubbles generated by aeration will carry some impurities such as grease and fiber and float on the water surface, gradually forming a layer of scum on the surface of the sewage, so that when draining, part of the scum will flow into the water inlet 4001 together with the clear liquid. At this time, if it is intercepted by the second filter 6, since the scum contains more impurities such as grease and fiber, the scum is very easy to adhere to the second filter 6, causing the second filter 6 to be blocked, which leads to a heavy filtering burden on the second filter 6. Before the drainage operation is performed, the electric slider is first controlled to drive the baffle 5 to slide upward, so that the baffle 5 moves up to block the water inlet 4001. At this time, the baffle 5 drives the second filter screen 6 to rotate to tilt toward the lower left side, and then the electric guide rail 2 drives the connecting frame 3 and the shell 4 and the connected parts to move downward, so that the baffle 5 is completely immersed in the water, and the water flow carries the scum over the baffle 5 and falls onto the second filter screen 6, and then the scum is intercepted by the second filter screen 6, and most of the clear liquid passes through the second filter screen 6 and is discharged from the drainage branch pipe 101 and the drainage branch pipe 101. The first filter screen 6 is inclined toward the left lower side, and the second filter screen 6 is inclined toward the left lower side. Therefore, the scum on the second filter screen 6 can be driven to flow to the first guide slope 4003 in time by this part of water flow, and then flow to the outlet of the slag discharge pipe 201 along the first guide slope 4003, and then be discharged outward through the slag discharge pipe 201, thereby achieving the discharge of scum on the water surface in advance, effectively reducing the subsequent filtering burden of the second filter screen 6. After the scum on the water surface is discharged, the electric guide rail 2 can be controlled to drive the shell 4 to move up to the water inlet 4001 and be flush with the water surface, and the electric slider can be controlled to drive the baffle 5 to reset downward so that the opening 5001 is aligned with the water inlet 4001 to perform conventional drainage operations. The suspended impurities in the clear liquid are intercepted by the second filter screen 6 inclined toward the lower right side. At this time, the clear liquid can all pass through the second filter screen 6 and be discharged from the drainage branch pipe 101, thereby avoiding partial clear liquid from being discharged from the slag discharge pipe 201, thereby reducing the loss of clear liquid.

[0046] It should be noted that when the shell 4 moves downward and is immersed in water, the second guiding slope 4004 inclined from the lower left side to the upper right side can push the scum on its lower side to move rightward to avoid that the scum is pressed into the water by the shell 4 and cannot be discharged.

[0047] like Figure 10As shown, when the housing 4 moves downward until its bottom is lower than the drain pipe 102, the clear liquid flowing into the housing 4 cannot be discharged through the drain branch pipe 101 from the drain pipe 102. As a result, the clear liquid accumulates continuously in the housing 4 until it flows over the partition plate 4002 and onto the first guiding inclined surface 4003. Then, the floating scum and suspended impurity substances on the first guiding inclined surface 4003 are carried by the water flow into the slag discharge pipe 201, preventing the floating scum and suspended impurity substances from continuously accumulating on the first guiding inclined surface 4003. Moreover, the inside of the housing 4 is flushed and cleaned by the clear liquid, so there is no need to additionally arrange a cleaning pipeline in the housing 4. Then, the electric guide rail 2 is controlled to drive the housing 4 to reset upward. During this process, the clear liquid in the housing 4 is discharged through the slag discharge pipe 201 and the drain branch pipe 101 respectively.

[0048] Embodiment 2

[0049] On the basis of Embodiment 1, as Figures 4-8 shown, it further includes an electric rotating shaft 202. The electric rotating shaft 202 is connected to the inside of the housing 4 through a fixing plate. The electric rotating shaft 202 is located above the pipe orifice of the slag discharge pipe 201, and four cutting blades 20201 are fixedly connected to the lower side of the electric rotating shaft 202.

[0050] When the clear liquid continuously accumulates in the housing 4 until it flows over the partition plate 4002 and onto the first guiding inclined surface 4003, so that the floating scum and suspended impurity substances on the first guiding inclined surface 4003 are carried by the water flow into the slag discharge pipe 201, since the floating scum contains fibrous impurities, in order to prevent the fibrous impurities from blocking the slag discharge pipe 201, the cutting blades 20201 are driven to rotate by the electric rotating shaft 202, so as to cut up the fibrous impurities in the floating scum, thereby preventing the fibrous impurities from blocking the slag discharge pipe 201.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
