[0002] At present, sewage refers to the discharged water from life and production that is polluted to a certain extent. The organic matter, nitrogen, phosphorus and other nutrients in the sewage will lead to eutrophication of water bodies, causing a large number of aquatic organisms such as algae to reproduce, consuming dissolved oxygen in the water, deteriorating the water body, and affecting the survival of aquatic organisms. At the same time, harmful substances in sewage will penetrate into the soil, destroy the soil structure, affect soil fertility, and lead to reduced crop yields or quality decline. At the same time, pollutants in the soil may also enter the human body through the food chain, endangering human health. Sewage treatment equipment is a series of devices used to treat various sewage to meet discharge standards or reuse states, including aeration tanks, secondary sedimentation tanks, sludge return systems, etc.

[0013] The present invention provides a solid-liquid separation liquid treatment equipment for sewage treatment. It has the following beneficial effects:

[0014] 1. The solid-liquid separation liquid treatment equipment for sewage treatment increases the air pressure during the accumulation process by introducing gas, causing the sliding plate to compress the elastic cover to deform and slide, so that the connecting column drives the block to move, and opens different gaps according to the air pressure to guide the gas out and contact the sewage to achieve aeration treatment of the sewage. At this time, the gap between the block and the through groove opens the same gap to evenly guide the gas, and at the same time cooperates with the arc cover and the side pad strip to make the gas contact the newly introduced sewage first.

[0015] 2. The solid-liquid separation liquid treatment equipment for sewage treatment cooperates with the arc cover through side pads. While the arc cover blocks the newly introduced sewage, the side pads close the gap at the bottom of the through-channel pipe to prevent the newly introduced sewage from flowing out of the inner side of the arc cover through the bottom gap, resulting in part of the sewage that cannot be aerated.

[0016] 3. The solid-liquid separation liquid treatment equipment for sewage treatment, through the buoyancy of the buoyancy ring, when the outlet speed of the outlet pipe is lower than the speed of the introduction into the aeration tank, the liquid level rises and covers the position of the outlet pipe, so that the buoyancy ring drives the chute plate to move upward, and the sealing block closes the chute plate, thereby blocking the gas outlet path of the chute pipe, causing the gas to accumulate in the aeration tank, increasing the air pressure at the top of the liquid surface, and accelerating the flow rate of the discharged sewage, to prevent the difference between the import and export flow rates, which will lead to an increase in the internal water pressure of the equipment and cause damage.

[0017] 4. The solid-liquid separation liquid treatment equipment for sewage treatment, through the guiding effect of the guide plate, cooperates with the aeration treatment work of the aeration mechanism to guide the sewage obliquely downward into the aeration mechanism, so that the sewage impacts the side pads to prevent direct impact on the arc cover and the through-channel pipe, resulting in an accelerated sewage flow rate at the sewage aeration position, resulting in insufficient aeration reaction.

[0018] 5. The solid-liquid separation liquid treatment equipment for sewage treatment, through the conduction of the inner wall of the hollow cylinder, cooperates with the inclined surface of the bottom end of the fixed cylinder, so that the sewage impacting downward becomes an inclined downward impact, so that the sewage drives the introduced sediment to impact the inclined baffle frame, so that the inclined baffle frame blocks the sediment, and cooperates with the inclined surface of the inclined baffle plate, so that during the sewage introduction process, the upper sewage is driven less, preventing the bottom sediment from being driven.

An elastic cover 209 is fixedly installed, and a connecting column 211 is fixedly installed on the other side of the sliding plate 210. A stopper 212 is fixedly installed on the top of the connecting column 211. After the sewage enters the aeration mechanism 2, the sewage rushes obliquely downward into the aeration box 201. The arc cover 207 cooperates with the side pad 206 to limit the sewage that has just entered. At the same time, the air pump 6 introduces the gas into the slot pipe 205 through the connecting head 203. During the continuous introduction of gas by the air pump 6, the air pressure in the slot pipe 205 is The air pressure gradually increases, and the sliding plate 210 slides on the inner wall of the inner cushion tube 208, so that the sliding plate 210 compresses the elastic cover 209 to deform and compress, so that the sliding plate 210 drives the connecting column 211 to slide, and the connecting column 211 drives the stopper 212 to move, so that the stopper 212 opens the through slot of the through slot tube 205. According to the pressure of the air pressure, different gaps are opened between the through slot and the stopper 212, and the stopper 212 is evenly installed on the top of the connecting column 211 along the axial direction, and the stopper 212 and the through slot are one by one. Corresponding to and slidably fitting with the inner wall of the through-slot pipe 205, an arc-shaped cover 207 is fixedly installed on one side of the inner wall of the aeration box 201 close to the connecting mechanism 4, the end of the arc-shaped cover 207 away from the aeration box 201 is an arc-shaped plate and there is a gap with the bottom of the inner wall of the aeration box 201, and a side pad 206 is fixedly installed on one side of the bottom of the inner wall of the aeration box 201 close to the connecting mechanism 4, and the side pad 206 is located obliquely below the side of the through-slot pipe 205 close to the connecting mechanism 4 and fits tightly with the outer side of the through-slot pipe 205.

[0038] An air groove is provided at the center of the top of the aeration box 201, and the side of the aeration box 201 away from the connecting mechanism 4 is fixedly connected to the outlet pipe 7, a chute pipe 204 is fixedly installed at the air groove of the aeration box 201, a chute cover 202 is fixedly installed at the top of the outer side of the chute pipe 204, the outer side of the chute cover 202 is evenly provided with chute grooves, the outer bottom of the chute pipe 204 is evenly provided with chute grooves, and a chute plate 213 is slidably installed at the chute of the chute pipe 204, and a buoyancy ring 214 is fixedly installed at the bottom of the chute plate 213. The aerated liquid flows through the gap between the arc cover 207 and the aeration box 201, and is continuously accumulated in the aeration box 201 until the liquid level rises to the position of the outlet pipe 7, and the sewage is discharged, and the introduced gas and sewage are separated. The gas generated by the reaction is discharged from the aeration box 201 through the outlet pipe 7 and the chute pipe 204. When the speed of the introduced sewage is too fast and the outlet pipe 7 cannot quickly discharge the sewage, the liquid surface contacts the buoyancy ring 214, and the chute plate 213 is driven to move upward through the buoyancy ring 214, so that the chute plate 213 drives the sealing block 216, so that the sealing block 216 blocks the chute of the chute plate 215. At this time, the liquid surface is higher than the outlet pipe 7, and the gas cannot be discharged from the outlet pipe 7 and the chute pipe 204. It accumulates in the aeration box 201, and the air pressure gradually increases, which speeds up the sewage discharge. The inner wall of the chute pipe 204 is fixedly installed with the chute plate 215, and the position of the chute plate 215 is higher than the position of the outlet pipe 7. The sealing block 216 is fixedly installed at the center of the top of the chute plate 213.

[0039] The second embodiment is based on the first embodiment. Figures 8 to 9 As shown, the connecting mechanism 4 includes an oblique square tube 41, the bottom end of the oblique square tube 41 is fixedly connected to the outside of the aeration box 201, and the top end of the oblique square tube 41 is fixedly connected to the outside of the sand removal mechanism 3, the sand removal mechanism 3 is connected to the aeration mechanism 2 through the oblique square tube 41, and a guide plate 42 is fixedly installed at the bottom of the inner wall of the oblique square tube 41, and there is a gap between the bottom end of the guide plate 42 and the inner wall of the oblique square tube 41. When sewage is introduced into the connecting mechanism 4, the sewage enters the oblique square tube 41. During the entry process, the arc surface of the arc baffle 43 blocks the impact of the sewage, so that the overflowed sewage can flow smoothly into the oblique square tube 41, so that the sewage is conducted downward along the oblique square tube 41. , introduced into the aeration mechanism 2, and the bottom end of the guide plate 42 is inclined from top to bottom toward one side of the aeration mechanism 2, an arc baffle 43 is fixedly installed on the top of the inner wall of the oblique square tube 41, and the bottom end of the arc baffle 43 is curved in an arc shape toward one side of the aeration mechanism 2, and an inclined block 44 is fixedly installed at the center position of the inner wall of the oblique square tube 41. When the sewage flows on the inner wall of the oblique square tube 41, the flowing sewage is diverted by the inclined block 44, so that the sewage flows downward evenly. At the same time, in the process of introducing the aeration mechanism 2, the sewage flowing out of the oblique square tube 41 is guided by the guide plate 42, so that the sewage is obliquely flushed into the aeration mechanism 2 downward, and the inclined blocks 44 are symmetrically installed along the center position of the axis of the oblique square tube 41.

[0040] The third embodiment is based on the first and second embodiments. Figure 10 to Figure 11 As shown, the sand removal mechanism 3 includes a sand removal box 301, a connecting pipe 302 is fixedly installed on the top of the sand removal box 301, the connecting pipe 302 is evenly installed along the axis of the sand removal box 301, and the top of the connecting pipe 302 is fixedly connected to the introduction pipe 5, the bottom end of the introduction pipe 5 passes through the sand removal box 301 and extends to the inside thereof, in the process of sewage flowing downward along the inner wall of the fixed cylinder 303, the flow of sewage along the inner wall of the fixed cylinder 303 is limited by the flow limiting disk 308, and the sewage is continuously accumulated in the sand removal box 301, so that the upper sewage first passes over the inclined baffle 305, overflows the sand removal box 301, and is introduced into the connecting mechanism 4, the bottom of the inner wall of the sand removal box 301 is fixedly installed with an inclined baffle frame 304, and the side of the inner wall of the sand removal box 301 close to the connecting mechanism 4 is fixedly installed with an inclined baffle frame 304.

[0041] A fixed cylinder 303 is fixedly installed on the top of the inner wall of the sand removal box 301. The fixed cylinder 303 is located just below the connecting pipe 302 and corresponds to the connecting pipe 302 one by one. The bottom end of the fixed cylinder 303 is inclined outward. There is a gap between the bottom of the fixed cylinder 303 and the bottom of the inner wall of the sand removal box 301. A fixed ring 306 is fixedly installed on the top of the inner wall of the fixed cylinder 303. A hollow cylinder 307 is fixedly installed on the inner wall of the fixed ring 306. A bevel cover 310 is fixedly installed on the bottom of the outer side of the hollow cylinder 307. When sewage is introduced for sand removal, it is connected with the introduction pipe 5 through the connecting pipe 302, so that after the sewage is introduced by the introduction pipe 5, it is introduced into the sand removal box 301 along the connecting pipe 302. In the process of being led out from the connecting pipe 302, the sewage first enters the interior of the fixed cylinder 303. After the sewage enters the fixed cylinder 303, it flows along the fixed cylinder The inner wall of 303 flows downward, so that the fixed cylinder 303 cooperates with the hollow cylinder 307 to impact the bottom of the inner wall of the sand removal box 301. At the same time, during the impact process, the sewage flowing downward along the inner wall of the fixed cylinder 303 cooperates with the inclined surface of the inclined surface cover 310 at the bottom of the fixed cylinder 303, so that the sewage that impacts vertically downward becomes an oblique impact outward, driving the sewage inside the hollow cylinder 307 to impact obliquely outward, driving the precipitated fine sand particles in the sewage to impact the oblique baffle frame 304, so that the oblique baffle frame 304 blocks the fine sand particles. The outer side of the oblique surface cover 310 is an inclined surface inclined outward from top to bottom. The outer side of the hollow cylinder 307 is slidably installed with a flow limiting disk 308. There is a gap between the outer side of the flow limiting disk 308 and the inner wall of the fixed cylinder 303, and a floating ring 309 is fixedly installed at the bottom of the flow limiting disk 308.

[0042] When in use, the sewage is introduced into the sand removal mechanism 3 through the introduction pipe 5 by connecting the introduction pipe 5 and the outlet pipe 7 to the sewage pipe respectively, and the sand removal treatment is performed on the introduced sewage through the sand removal mechanism 3, so that the silt brought by the sewage in the process of pipeline circulation is cleaned up. At the same time, in the process of continuous accumulation of sewage, the liquid level rises until it overflows the sand removal mechanism 3, and the overflowed sewage is introduced into the aeration mechanism 2 through the connecting mechanism 4. The air inlet end of the air pump 6 is connected with the required gas pipeline, so that the air pump 6 introduces the gas from the air outlet end into the aeration mechanism 2, and the sewage is aerated. The sewage after aeration treatment is discharged through the outlet pipe 7.

[0043] When the sewage is introduced for sand removal, it is connected with the introduction pipe 5 through the connecting pipe 302, so that after the sewage is introduced by the introduction pipe 5, it is introduced into the sand removal box 301 along the connecting pipe 302. In the process of being led out from the connecting pipe 302, the sewage first enters the interior of the fixed cylinder 303. After the sewage enters the fixed cylinder 303, it flows downward along the inner wall of the fixed cylinder 303, so that the fixed cylinder 303 cooperates with the hollow cylinder 307 to impact the bottom of the inner wall of the sand removal box 301. At the same time, during the impact process, the sewage flowing downward along the inner wall of the fixed cylinder 303 is inclined outward through the bottom end of the fixed cylinder 303. The inclined surface cooperates with the inclined surface of the inclined cover 310, so that the sewage that impacts vertically downward changes to impact obliquely outward, driving the sewage inside the hollow cylinder 307 to impact obliquely outward, driving the precipitated fine sand particles in the sewage to impact the inclined baffle frame 304, so that the inclined baffle frame 304 blocks the fine sand particles. At the same time, in the process of the sewage flowing downward along the inner wall of the fixed cylinder 303, the flow of sewage along the inner wall of the fixed cylinder 303 is limited by the flow limiting disk 308, and the sewage is continuously accumulated in the sand removal box 301, so that the upper sewage first passes over the inclined baffle plate 305, overflows the sand removal box 301, and is introduced into the connecting mechanism 4.

[0044] When sewage is introduced into the connecting mechanism 4, the sewage enters the oblique square tube 41. During the process of entering, the impact of the sewage is blocked by the arc surface of the arc baffle 43, so that the overflowing sewage can smoothly flow into the oblique square tube 41, and the sewage is conducted downward along the oblique square tube 41 and introduced into the aeration mechanism 2. At the same time, when the sewage flows on the inner wall of the oblique square tube 41, the flowing sewage is diverted by the oblique block 44, so that the sewage flows downward evenly. At the same time, in the process of being introduced into the aeration mechanism 2, the sewage flowing out of the oblique square tube 41 is guided by the guide plate 42, so that the sewage rushes obliquely downward into the aeration mechanism 2.

[0045] After the sewage enters the aeration mechanism 2, it rushes obliquely downward into the aeration box 201, and the newly entered sewage is restricted by the arc cover 207 and the side pad 206. At the same time, the air pump 6 introduces the gas into the through-slot pipe 205 through the connecting head 203. During the continuous introduction of gas by the air pump 6, the air pressure in the through-slot pipe 205 gradually increases, and the air pressure pushes the sliding plate 210 to slide on the inner wall of the inner pad cylinder 208, so that the sliding plate 210 compresses the elastic cover 209 to deform and compress, so that the sliding plate 210 drives the connecting column 211 to slide, and the connecting column 211 drives the block 212 to move, so that the block 212 opens the through slot of the through-slot pipe 205, and controls the opening of different gaps between the through slot and the block 212 according to the pressure of the air pressure. The liquid flows through the gap between the arc cover 207 and the aeration box 201, and accumulates in the aeration box 201 until the liquid level rises to the position of the outlet pipe 7, and the sewage is discharged. The gas produced by the reaction of the introduced gas with the sewage is discharged from the aeration box 201 through the outlet pipe 7 and the chute pipe 204. When the speed of the introduced sewage is too fast and the outlet pipe 7 cannot quickly discharge the sewage, the liquid surface contacts the buoyancy ring 214, and the chute plate 213 is driven to move upward through the buoyancy ring 214, so that the chute plate 213 drives the sealing block 216, so that the sealing block 216 blocks the chute of the chute plate 215. At this time, the liquid level is higher than the outlet pipe 7, and the gas cannot be discharged from the outlet pipe 7 and the chute pipe 204, and accumulates in the aeration box 201, and the air pressure gradually increases, thereby accelerating the speed of sewage discharge.
