Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a circulating sewage treatment device used in a garbage transfer station. Background Art

[0002] With the acceleration of urbanization, the amount of urban garbage generated is increasing. As an important part of the urban garbage treatment system, the garbage transfer station plays a key role in the collection and transportation of garbage. However, a large amount of sewage will be generated during the operation of the garbage transfer station, which needs to be purified by sewage treatment equipment. During the treatment, the sewage enters the aeration tank in the sewage treatment equipment for aeration. Aerobic bacteria and microorganisms are added to the aeration tank in advance, and then oxygen is continuously transported to the sewage. These microorganisms use oxygen to decompose the organic matter in the sewage into carbon dioxide and water, thereby removing the organic matter in the sewage and reducing COD and BOD. After aeration, the sewage enters the first sedimentation tank and the second sedimentation tank in turn for precipitation, and is discharged after becoming clean water.

[0003] In the prior art, external oxygen is delivered to the aeration head through a delivery pipe to aerate the sewage in the aeration tank. After a period of use, a lot of sludge is easily attached to the surface of the aeration head. Although the surface of the aeration head can be backwashed and some sludge can be washed away by the backwashing pipe, there will still be a lot of sludge attached to the surface. At this time, the sludge will form an obstruction layer between the aeration head and the sewage, increasing the resistance of oxygen transfer to the sewage, making it difficult for oxygen to effectively diffuse from the aeration head to the sewage, and also making the bubbles generated by the aeration head of different sizes, which will reduce the contact area between the bubbles and the sewage and reduce the time the bubbles stay in the sewage, thereby reducing the aeration efficiency, and further affecting the sewage treatment effect. For this reason, we propose a circulating sewage treatment equipment for garbage transfer stations. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The cleaning mechanism of the present invention is designed such that, during use, the rotating disk drives the multiple groups of circular brushes below to rotate to remove the sludge attached to the upper surface of the aeration head, and the circular brush can reciprocate left and right in the aeration tank, and can clean different positions inside the aeration tank.

[0020] (2) The auxiliary cleaning part designed in the present invention can remove part of the sludge attached to the surface of the conveying pipe while the circular brush moves back and forth in the left and right directions. The triangular push plate pushes the annular brush to move to remove the sludge attached to the surface of the conveying pipe, thereby preventing a lot of sludge attached to the surface of the conveying pipe from scattering outward in blocks during aeration and drifting above the aeration head or attaching to the surface of the aeration head to affect oxygen ejection and thus affect the aeration effect.

The annular brush can rotate while moving, thereby increasing the cleaning effect of the sludge on the surface of the conveying pipe. Compared with the linear cleaning of a simple annular brush, the rotating annular brush can clean the conveying pipe more comprehensively and efficiently, thereby improving the cleaning effect and being able to more thoroughly remove the sludge on the surface of the conveying pipe.

[0022] (4) The scraper of the present invention is designed so that when in use, the scraper can scrape the sludge accumulated on the bottom of the inner wall of the aeration tank, cooperate with other cleaning components and the water sprayed from the backwash head to clean the sludge on the surfaces of different objects in the aeration tank from different angles, thereby increasing the cleaning of sludge in various parts of the entire aeration tank and reducing the probability that the sludge in the aeration tank will be difficult to enter the first sedimentation tank for sedimentation and purification due to the influence of long-term sludge accumulation.

[0045] Embodiment 2

[0046] Based on Example 1, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Fig. 9 The moving component includes a second long rail 220 fixed on the inner wall of the box body 100, the friction wheel 209 contacts the surface of the second long rail 220, a driving motor 200 is fixedly arranged on one side of the box body 100, and the working end of the driving motor 200 extends to the end of the screw rod 201, a slide rail 204 is slidably arranged between the first long rail 202 and the second long rail 220, a screw rod 201 is rotatably arranged on the top of the first long rail 202, a nut seat 203 is arranged on the outside of the screw rod 201, and an L-shaped frame is fixedly arranged between the nut seat 203 and the slide rail 204.

[0047] The cleaning mechanism of the present invention is designed such that during use, the rotating rotating disk 211 drives the multiple groups of circular brushes 218 below to rotate to remove the sludge attached to the upper surface of the aeration head 108, and the circular brushes 218 can reciprocate left and right in the aeration tank 101, and can clean different positions inside the aeration tank. At the same time, in cooperation with the backwash head, the clean water precipitated in the second sedimentation tank 104 is sprayed out through the backwash head to wash the upper surface of the aeration head 108, thereby increasing the sludge removal effect and ensuring the aeration effect of the subsequent aeration head 108. In addition, the circular brush 218 is connected to the T-bar 210 through the ball seat 217, and can be tilted in different directions during the brushing process of the aeration head 108, so that the multiple circular brushes 218 can fit the upper surface of the aeration head 108, thereby increasing the cleaning effect.

[0048] In summary, the sewage in the garbage transfer station enters the aeration tank 101, and then the aeration head 108 is supplied with air through the conveying pipe 102. The aeration head 108 aerates the sewage in the aeration tank 101. After a period of use, some sludge will adhere to the surface of the aeration head 108. At this time, the water pump is turned on, and water is sprayed outward through the backwash head to wash the aeration tank 101 and various objects in the aeration tank 101. At the same time, the drive motor 200 is turned on, and the working end of the drive motor 200 rotates to drive the screw rod 201 to rotate, and the screw rod 201 drives the nut seat 203 to move. At this time, the nut seat 203 drives the slide rail 204 on the first long rail 202 and the second long rail 220 through the L-shaped frame. The slide rail 204 moves to the right, and the two ends of the slide rail 204 slide inside the first long rail 202 and the second long rail 220 respectively. When the slide rail 204 moves, the bracket 208 is driven to move, and the bracket 208 drives the support bearing 206 and the mounting bearing 212 to move, thereby driving the top rod 207 and the rotating disk 211 to move, and the rotating disk 211 drives the T-shaped rod 210 and the round brush 218 at the bottom to move. When the round brush 218 moves, the friction wheel 209 at the top of the top rod 207 contacts the surface of the second long rail 220, thereby enabling the friction wheel 209 to rotate, driving the top rod 207 to rotate, and then driving the guide wheel on the top rod 207 to rotate. The transmission belt 205 drives the remaining multiple groups of top rods 207 to rotate, which in turn drives all the rotating disks 211 to rotate, and then all the round brushes 218 rotate. After the rotating and moving round brush 218 contacts the aeration head 108, the round brush 218 moves upward or downward under the influence of the conical surface on the upper surface of the aeration head 108, driving the T-shaped rod 210 to move up and down. At this time, the connecting spring 215 is stretched or reset, and the T-shaped rod 210 rotates in the fixing ring 219 and moves up and down. Under the action of the ball seat 217, the round brush 218 can be adaptively tilted according to the angle of the conical surface after contacting the conical surface on the upper surface of the aeration head 108. , so that the round brush 218 can always be in close contact with the conical surface of the aeration head 108, and at the same time, the round brush 218 rotates to clean the sludge attached to the upper surface and the outer surface of the aeration head 108. As the round brush 218 moves, the bottom of the round brush 218 is separated from the surface of the aeration head 108, and then the round brush 218 contacts another group of aeration heads 108 to clean them. This operation is repeated until it moves to the right to the extreme position and stops. At this time, the driving motor 200 is reversed, and the nut seat 203 moves to the left, thereby driving the round brush 218 to move to the left, and so on, so that the round brush 218 can reciprocate in the left and right directions and rotate to clean the outer surface of the aeration head 108.

[0049] Embodiment 3

[0050] Based on Example 2, please refer to Figure 4 , Figure 5 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.13 and Fig.14 , multiple groups of auxiliary cleaning parts are arranged on the outside of the delivery pipe 102, and the auxiliary cleaning parts include a sliding ring 402, an annular brush 400 and a fixed column 405 fixed on the outer wall of the mounting bearing 212, which are sleeved on the outside of the delivery pipe 102. The sliding ring 402 can limit the annular brush 400 moving on the delivery pipe 102, thereby increasing its stability during movement. Multiple groups of L-shaped rods are fixedly arranged between the sliding ring 402 and the annular brush 400, and multiple groups of rolling balls 406 are rollingly arranged on the inner wall of the sliding ring 402. The outer wall of the rolling balls 406 contacts the outer wall of the delivery pipe 102, and the rolling balls 406 can reduce the friction and wear on the outer wall of the delivery pipe 102 when the sliding ring 402 slides back and forth on the delivery pipe 102;

[0051] A fixed plate 401 is fixedly provided on the outside of the fixed column 405, and a triangular push plate 403 is slidably provided on the bottom of the fixed column 405. The end of the triangular push plate 403 can move in a direction close to or away from the fixed column 405. A T-shaped plate 408 is fixedly provided on the triangular push plate 403. A T-shaped column 404 is slidably provided inside the fixed column 405. The T-shaped column 404 slides in the fixed column 405 to increase the stability of the triangular push plate 403 when moving. The end of the T-shaped column 404 extends to the surface of the T-shaped plate 408. A mounting spring 407 is sleeved on the outside of the T-shaped column 404, and the two ends of the mounting spring 407 are fixedly connected to the T-shaped plate 408 and the fixed column 405 respectively. The end surface of the triangular push plate 403 can contact the annular brush 400.

[0052] The auxiliary cleaning parts designed in the present invention can remove part of the sludge attached to the surface of the conveying pipe 102 while the round brush 218 reciprocates in the left and right directions. The triangular push plate 403 pushes the annular brush 400 to move to remove the sludge attached to the surface of the conveying pipe 102, thereby preventing a lot of sludge attached to the surface of the conveying pipe 102 from scattering outward in blocks during aeration and drifting above the aeration head 108 or attaching to the upper surface of the aeration head 108 to affect the oxygen ejection and thus affect the aeration effect. At the same time, the cleanliness of the surface of the conveying pipe 102 can be increased through cleaning, thereby reducing the fatigue of subsequent cleaning of the surface of the conveying pipe 102.

[0053] In summary, when the rotating disk 211 and the external mounting bearing 212 move to the right, the triangular push plate 403 below will be driven to move through the fixed column 405. When the triangular push plate 403 moves, the side surface of the end will contact the side surface of the annular brush 400 located on the conveying pipe 102, driving the annular brush 400 and the sliding ring 402 on the side of the annular brush 400 to move. At this time, the annular brush 400 begins to sweep the sludge attached to the outer wall of the conveying pipe 102. When the sliding ring 402 moves to the right and contacts and is blocked by another set of aeration heads 108 on the right conveying pipe 102, the triangular push plate 403 moves in the direction close to the fixed column 405, driving the T-shaped plate 408 and the T-shaped column 404 located on the T-shaped plate 408 to move. At this time, the mounting spring 407 is compressed, and then when the side surface of the end of the triangular push plate 403 is separated from the annular brush 400, the mounting spring 407 is reset, pushing the end of the T-shaped plate 408 away from the fixed column 405. The fixed column 405 moves in the direction of the fixed column 405, driving the T-shaped column 404 and the triangular push plate 403 to move accordingly, and then the end of the triangular push plate 403 no longer contacts the annular brush 400. When the triangular push plate 403 moves to the left, according to the same principle as above, the annular brush 400 located on the conveying pipe 102, which has previously moved to the right, begins to move to the left, and so on. The annular brush 400 moves back and forth in the left and right directions to clean part of the sludge attached to the surface of the conveying pipe 102, so as to prevent a lot of sludge attached to the surface of the conveying pipe 102 from loosening and scattering outward in blocks during the aeration process, and then drifting to the top of the aeration head 108 or attaching to the upper surface of the aeration head 108 with the movement of the water flow, affecting the smoothness of the oxygen spraying above the aeration head 108, thereby affecting the aeration effect. At the same time, the cleanliness of the surface of the conveying pipe 102 can be increased by cleaning, and the subsequent work fatigue of cleaning the surface of the conveying pipe 102 can be reduced.

[0054] The fixed plate 401 is provided with a rotating member for driving the annular brush 400 to rotate. The rotating member includes a lower ring 216 fixed to the bottom of the rotating disk 211 and a rotating rod 502 rotatably arranged inside the fixed plate 401. A rotating disk is sleeved and fixed on the top of the rotating rod 502. When the lower ring 216 rotates, the rotating disk is driven to rotate, and the rotating disk contacts the outer wall of the lower ring 216.

[0055] A first bevel gear 503 is fixedly mounted on the bottom of the rotating rod 502, a frame 501 is fixedly mounted on the bottom of the fixed column 405, a rotating shaft 506 is rotatably mounted on the frame 501, a roller 500 is arranged on the outside of the rotating shaft 506, and the roller 500 can contact the bottom of the annular brush 400, a rubber ring is arranged on the outer surface of the roller 500, and the rubber ring contacts the bottom outer wall of the annular brush 400 to increase the friction between the roller 500 and the annular brush 400, and the edges on both sides of the roller 500 and the rubber ring are both chamfered structures, which are convenient for contacting the bottom surface of the annular brush 400, an extension shaft is also rotatably mounted on the frame 501, a second bevel gear 504 is fixedly mounted on the outside of the extension shaft, and a transmission belt 505 is arranged between the extension shaft and the rotating shaft 506.

[0056] The present invention has a designed rotating part. When the triangular push plate 403 pushes the annular brush 400 to move back and forth to clean the sludge attached to the surface of the conveying pipe 102, the annular brush 400 can be rotated, so that the annular brush 400 can rotate while moving, thereby increasing the cleaning effect of the sludge on the surface of the conveying pipe 102. Compared with the linear cleaning of the simple annular brush 400, the rotating annular brush 400 can clean the conveying pipe 102 more comprehensively and efficiently, thereby improving the cleaning effect and being able to more thoroughly remove the sludge on the surface of the conveying pipe 102.

[0057] In summary, when the fixed column 405 moves, it will drive the fixed plate 401, the rotating rod 502, the frame 501 and the roller 500 to move. At this time, the rotating disk located at the top of the rotating rod 502 contacts and rotates with the lower ring 216 located below the rotating disk 211. The rotating rotating disk drives the rotating rod 502 to rotate. The rotating rod 502 drives the extension shaft to rotate through the meshing action of the first bevel gear 503 and the second bevel gear 504, and then drives the rotating shaft 506 to rotate through the transmission belt 505. The rotating shaft 506 drives the roller 500 to rotate, and then the rotating roller 500 contacts the moving The bottom surface of the annular brush 400 is touched and the annular brush 400 is driven to rotate. At this time, the annular brush 400 moving linearly on the conveying pipe 102 is rotated, thereby increasing the cleaning effect of the sludge on the surface of the conveying pipe 102. When the annular brush 400 contacts another set of aeration heads 108 during the movement, it is obstructed. At this time, the roller 500 is separated from the bottom surface of the annular brush 400. After passing through the obstructed aeration head 108, the roller 500 contacts another set of annular brushes 400. This is repeated until the roller 500 contacts the bottom surface of the annular brush 400 and drives the annular brush 400 to rotate.

The scraper includes a scraper 301 slidably arranged at the bottom of the inner wall of the aeration tank 101, and a stirring blade 302 is fixedly arranged on the top of the scraper 301. A plurality of groups of connecting rods 300 are fixedly arranged on the top of the stirring blade 302, and the end of the connecting rod 300 extends to the surface of the slide rail 204. The scraper 301 and the stirring blade 302 can not only stir the sludge accumulated at the bottom of the inner wall of the aeration tank 101, but also stir the water when the water in the sewage tank 101 rises, so as to increase the angle of the accumulated sludge and combine and mix with the water sprayed from the backwash head to enter the first sedimentation tank 103.

[0060] The scraper of the present invention is designed so that the scraper 301 can scrape the sludge accumulated on the bottom of the inner wall of the aeration tank 101 during use, and cooperate with other cleaning components and the water sprayed from the backwash head to clean the sludge on the surfaces of different objects in the aeration tank 101 from different angles, thereby increasing the cleaning of sludge in various parts of the entire aeration tank 101 and reducing the probability of long-term accumulation of sludge in the aeration tank 101 making it difficult for the sludge in the aeration tank 101 to enter the first sedimentation tank 103 for sedimentation and purification.

[0061] In summary, when the slide rail 204 moves back and forth, it will drive the connecting rod 300 to move, and the connecting rod 300 will drive the stirring blades 302 and the scraper 301 to move. At this time, the sludge accumulated at the bottom of the aeration tank 101 can be scraped and stirred. After the backwash head sprays water into the aeration tank 101, the water level in the aeration tank 101 continues to rise. At this time, the accumulated sludge can be scraped and stirred by the stirring blades 302 and the scraper 301 and mixed with the water in the aeration tank 101. Then, as the water level continues to rise, the sewage in the aeration tank 101 flows into the first sedimentation tank 103 for sedimentation, and the precipitated water flows into the second sedimentation tank 104 for sedimentation and purification, thereby reducing the probability that the sludge in the aeration tank 101 is difficult to enter the first sedimentation tank 103 for sedimentation and purification due to the influence of long-term accumulation of sludge.

[0062] In this embodiment, a backwash pipe 105 is fixedly provided on the top of the inner wall of the aeration tank 101, and the backwash pipe 105 is a concave structure when viewed from above, and multiple groups of backwash heads are fixedly provided on the outside of the backwash pipe 105, and a connecting pipe 106 is provided inside the second sedimentation tank 104, and the end of the connecting pipe 106 extends to the surface of the backwash pipe 105, and a water pump is provided on the connecting pipe 106. When the aeration head 108 in the aeration tank 101 is cleaned, water is sprayed from the backwash head on the backwash pipe 105 to clean the aeration tank. The clean water after sedimentation is extracted from the second sedimentation tank 104 by a water pump and transported to the backwash pipe 105 through the connecting pipe 106, and then sprayed out through the backwash head to flush the aeration tank 101. The sewage after flushing will flow back to the first sedimentation tank 103 and the second sedimentation tank 104 for sedimentation, completing the water cycle and reducing the use cost. There are connection ports for water to pass between the aeration tank 101 and the first sedimentation tank 103, and between the first sedimentation tank 103 and the second sedimentation tank 104.

[0063] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
