Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a floating sludge collecting device for a sewage treatment pool. Background Art

[0002] In the sewage treatment process, flocculation and sedimentation are essential steps in the treatment process. Generally, suspended solids in the sedimentation tank are adsorbed and precipitated by adding chemicals to remove suspended sludge in the sewage and improve water quality. However, during the sludge sedimentation process, due to the presence of fibers, wood chips, hair, bubbles and other substances in the sludge, the sludge floats to the surface of the sewage or suspends in the sewage, affecting the sedimentation treatment effect of the sewage. In addition, when the sludge structure is loose, the volume expands, and the density decreases, the generation of floating sludge will be aggravated, causing sewage turbidity and poor pollutant removal effect.

[0003] Invention patent CN112354225B discloses a floating sludge collection device for a sewage treatment pool, which uses a stirring screw to cooperate with an aeration head set below the water surface to form fine bubbles, thereby lifting the floating sludge suspended in the water to the water surface. However, during the sedimentation of sludge, the water flow in the sewage treatment pool needs to be kept relatively stable, especially the stability of the bottom water flow, to avoid the floating of the settled sludge.

For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0040] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0041] The embodiment of the present invention provides a device for collecting floating sludge in a sewage treatment pool. Figure 1 , 2 3. The floating sludge collecting device for the sewage treatment pool comprises a support frame 101, a plurality of rollers 103 are installed at the bottom of the support frame 101, and a structure composed of the support frame 101 and the rollers 103 is symmetrically distributed on both sides of the sewage pool. A collecting trough 104 is fixedly installed on the support frame 101, a first end of the collecting trough 104 is communicated with the sewage pool, a second end of the collecting trough 104 is fixedly connected and communicated with a collecting box 105, and the collecting box 105 is fixedly connected to the support frame 101, and a conveyor belt 106 is arranged and installed in the collecting trough 104, and the conveyor belt 106 can transfer the floating sludge at the edge of the sewage pool to the collecting box 105 for collection.

[0042] A suspension beam 102 is fixedly installed on the top of the support frame 101. The suspension beam 102 is located directly above the sewage pool. A lifting mechanism 200 is installed in the middle of the suspension beam 102. The lifting mechanism 200 includes a guide rail 204. A sliding mechanism 300 is installed on the guide rail 204 and reciprocates along its length. The lifting mechanism 200 can adjust the height of the sliding mechanism 300.

[0043] The sliding mechanism 300 includes a mounting block 305 on which a circulation mechanism 600 is mounted. The circulation mechanism 600 includes a water spray port 601 provided on the side of the mounting block 305 and a submersible pump 607 mounted below the collecting tank 104. The water outlet of the submersible pump 607 is connected and communicated with the water spray port 601 through a pipe.

[0044] Among them, a number of scrapers are evenly fixed on the outer surface of the conveyor belt 106, and the scrapers can overlap with the inner surface of the collecting trough 104, so as to transfer the floating sludge on the water surface at the edge of the sewage pool through the collecting trough 104 to the collecting box 105 for collection. The conveyor belt 106 is driven to rotate by at least two rollers that tension it. The installation and drive control method of the rollers are existing technologies and will not be repeated here.

[0045] Among them, the collecting trough 104 is arranged at an angle, and its inclination is from top to bottom and from outside to inside. In addition, the lower end surface of the collecting trough 104 is arranged below the water surface of the sewage pool, so that the floating sludge on the sewage pool can enter the collecting trough 104 under the driving action of the conveyor belt 106.

[0046] The water inlet of the submersible pump 607 is located below the liquid level of the sewage pool and close to the liquid level, and during operation, the height of the water spray port 601 is flush with the height of the water inlet of the submersible pump 607 .

[0047] Among them, the lifting mechanism 200 can adjust the height of the mounting block 305. When starting to work, the lifting mechanism 200 adjusts the height of the mounting block 305 downward until the water outlet 601 is located below the liquid level of the sewage pool, and the height of the water outlet 601 at this time is flush with the height of the water inlet of the submersible pump 607.

[0048] The specific working process of the above embodiment is as follows: the operator first adjusts the position of the device along the length direction of the pool edge. After the position is properly adjusted, the lifting mechanism 200 is driven to adjust the height of the sliding mechanism 300, so that the water spray port 601 opened on the mounting block 305 is below the liquid surface and is flush with the water inlet height of the submersible pump 607. At this time, the submersible pump 607 is started, and the submersible pump 607 pumps the sewage below the collecting tank 104 to the water spray port 601 through the pipeline and discharges it outward through the water spray port 601. Since the water spray port 601 is located in the middle of the sewage pool, a circulating water flow flowing from the middle to both sides is formed on the sewage water surface. On the one hand, the floating mud residue in the middle position is driven to the side of the sewage pool, and on the other hand, the sludge settled at the bottom of the pool will not be disturbed to cause secondary turbidity of the pool water.

[0049] The floating sludge driven to the side of the sewage pool is further transported to the collecting box 105 through the cooperation of the conveyor belt 106 and the collecting trough 104, thereby completing the collection of the floating sludge.

[0050] In addition, according to the distribution of floating mud residue in the actual working process, the operator can flexibly adjust the position of the mounting block 305 by controlling the reciprocating motion of the sliding mechanism 300 along the length direction of the guide rail 204 to better complete the collection of floating mud residue.

[0051] For further explanation of the present invention, see Figure 4 , 1 The circulation mechanism 600 also includes a confluence chamber 602 , a branch pipe 603 , a main pipe 604 , a telescopic pipe 605 , and a hose 606 .

[0052] The water spray port 601 is fixedly connected and communicated with the confluence chamber 602, the confluence chamber 602 is fixedly connected and communicated with the first ends of several branch pipes 603 along the length direction, the second ends of the branch pipes 603 are fixedly connected and communicated with the main pipe 604, the main pipe 604 is fixedly connected and communicated with the first end of the telescopic tube 605, the telescopic tube 605 is installed on the guide rail 204, the second end of the telescopic tube 605 is fixedly connected and communicated with the first end of the hose 606, and the second end of the hose 606 is fixedly connected and communicated with the water outlet of the submersible pump 607.

[0053] The telescopic tube 605 includes a plurality of tube sections which are sequentially sealed and sleeved, and the installation structure of the two tube sections which are sleeved together is as follows: Figure 6 As shown, the two pipe sections are sealed and connected via a sealing limit ring 608 and slide relative to each other, and a sealing limit ring 608 is fixedly installed at both ends of each pipe section; specifically: in the two interconnected pipe sections, the large-diameter pipe section is sealed and overlapped with the outer surface of the small-diameter pipe section via the sealing limit ring 608, and the small-diameter pipe section is sealed and overlapped with the inner surface of the large-diameter pipe section via the sealing limit ring 608, and the sealing limit rings 608 of the two pipe sections can be clamped with each other to prevent the pipe sections from detaching.

[0054] Among them, two groups of circulation mechanisms 600 are symmetrically distributed about the center of the installation block 305, so that the installation block 305 forms water flow circulation from the two sides facing the sewage pool, ensuring that the floating sludge is collected at the sewage pool sides at the same time.

[0055] Through the above structure, the present invention ensures that during the reciprocating motion of the sliding mechanism 300 along the length direction of the guide rail 204, the main pipe 604 is always connected to the hose 606 through the extension and contraction of the telescopic tube 605, and can ensure that the submersible pump 607 can smoothly transport the water flow through the branch pipe 603 and the main pipe 604 to the water outlet 601, thereby completing the circulation of the water flow.

[0056] For further explanation of the present invention, see Figure 2 The lifting mechanism 200 also includes a lifting plate 201, an electric cylinder 202, and a connecting plate 203. The lifting plate 201 is installed in a square through hole opened on the suspension beam 102 and moves along it. The lifting plate 201 is hingedly connected to the first end of the plurality of electric cylinders 202, and the second end of the electric cylinder 202 is hingedly connected to the suspension beam 102.

[0057] The bottom of the lifting plate 201 is fixedly connected to the guide rail 204 . The structure composed of the lifting plate 201 , the electric cylinder 202 and the guide rail 204 is symmetrically distributed in two groups about the width center of the suspension beam 102 , and the two groups of lifting plates 201 are fixedly connected by a plurality of connecting plates 203 .

[0058] In the above structure of the present invention, the simultaneous extension or shortening of multiple electric cylinders 202 is used to realize the simultaneous rising and falling of the two sets of lifting plates 201 and the guide rails 204, which further drives the rising and falling of the sliding mechanism 300 installed on the guide rails 204, thereby realizing the adjustment of the horizontal height of the mounting block 305, and then adjusting the height position of the water spray outlet 601 relative to the liquid surface to meet the usage requirements.

[0059] For further explanation of the present invention, see Figure 2 , 3 The sliding mechanism 300 also includes a driving wheel 301, a connecting block 302, a connecting shaft 303, and a motor 304. A plurality of driving wheels 301 are respectively rotatably mounted on the two guide rails 204. A plurality of driving wheels 301 located above a single guide rail 204 are respectively rotatably mounted on the connecting block 302. The driving wheels 301 distributed above the two guide rails 204 are respectively coaxially fixedly connected through the connecting shaft 303 in a one-to-one correspondence. The connecting shaft 303 is drivingly connected to the output end of the motor 304 through a transmission. The motor 304 is fixedly mounted on the connecting block 302, and the connecting block 302 is fixedly connected to the mounting block 305.

[0060] The output end of the motor 304 is coaxially fixed with the input end of the transmission, the transmission is fixedly mounted on the connecting block 302, and the output end of the transmission is coaxially fixed with the connecting shaft 303, thereby enabling the motor 304 to drive the connecting shaft 303 to rotate forward or reverse.

[0061] In the present invention, through the above structure, the motor 304 drives the driving wheels 301 located above the two guide rails 204 to rotate in the same direction through the connecting shaft 303. Through the interaction between the driving wheels 301 and the guide rails 204, the sliding mechanism 300 can slide back and forth along the length direction of the guide rails 204, thereby adjusting the specific position of the mounting block 305.

[0062] As another embodiment of the present invention, on the basis of the above embodiment, an aeration mechanism 500 is further installed at the bottom of the mounting block 305, see Figure 3 , 4 , the aeration mechanism 500 includes an inner chamber 501, a blower 502, a diverter pipe 503, an air delivery pipe 504, and an aeration hole 505;

[0063] An inner chamber 501 is provided inside the mounting block 305, the top of the inner chamber 501 is connected to the outside, a blower 502 is fixedly installed in the inner chamber 501, an air outlet of the blower 502 is fixedly connected and connected to a shunt pipe 503, the shunt pipe 503 is evenly fixed along the length direction and connected to the middle part of a plurality of gas pipes 504, both sides of the gas pipes 504 pass through the side walls of the mounting block 305 respectively, and a plurality of aeration holes 505 are evenly opened on the side walls of the gas pipe 504 located outside the mounting block 305.

[0064] The height of the air delivery pipe 504 is lower than the water spray port 601 , and the length of the water spray port 601 is greater than the length of the diversion pipe 503 .

[0065] There are two blowers 502 symmetrically distributed about the center of the diversion pipe 503 .

[0066] Among them, a one-way valve is installed at the air outlet of the blower 502, so that the outside air can be transported to the diversion pipe 503 through the blower 502, but the water in the sewage pool cannot flow back to the blower 502 through the diversion pipe 503, so as to avoid damage to the blower 502. The structure and installation method of the one-way valve are existing technologies and are no longer controlled here.

[0067] Through the above-mentioned embodiments, the present invention enables the blower 502 of the device to divert the gas in the inner chamber 501 through the diversion pipe 503 and transport it to each gas pipe 504 during operation, and discharge it into the sewage below the liquid level through a plurality of aeration holes 505. Since the gas pipe 504 is located below the water spray port 601, after the gas is discharged into the sewage through the gas pipe 504, the bubbles are more evenly dispersed in the sewage pool through the impact of the water flow from the water spray port 601.

[0068] The floating mud suspended in the sewage pool combines with the above-mentioned air bubbles, resulting in an increase in buoyancy, thereby bringing the floating mud out of the water surface and drifting to the edge of the pool under the impact of the water flow from the water spray port 601, completing the collection of the floating mud residue.

[0069] As another embodiment of the present invention, on the basis of the above embodiment, a blower mechanism 400 is further installed on the mounting block 305, see Figure 4 , 5 The hair dryer structure 400 includes an air hole 402 , a fan 403 , an electric telescopic rod 404 , a wind shield 405 , and a wind shield cover 406 .

[0070] A plurality of air holes 402 are provided on the mounting block 305, and the air holes 402 penetrate the top and the side of the mounting block 305, and a fan 403 is fixedly installed at the top opening of the air hole 402, and an electric telescopic rod 404 is installed on the side of the air hole 402, and the telescopic end of the electric telescopic rod 404 is hingedly connected to the first end of the wind shield 405, and the wind shield 405 is located directly below the fan 403, and the second end of the wind shield 405 is sleeved in the wind shield sleeve 406 and can move along it, and the end of the wind shield sleeve 406 away from the wind shield 405 is hinged at the bottom opening of the air hole 402.

[0071] Among them, two electric telescopic rods 404 are symmetrically distributed about the center of the wind shield 405, and the electric telescopic rods 404 are vertically installed on the side of the wind hole 402, so that during operation, its telescopic end can only be telescoped along the height direction, thereby adjusting the horizontal height of the first end of the wind shield 405.

[0072] Among them, the cross-sectional shape of the wind shield 405 is a square, and the cross-sectional shape of the inner surface of the wind shield cover 406 is a square that matches the cross-sectional shape of the wind shield 405. This structure is to ensure the extension and retraction of the wind shield 405 relative to the wind shield cover 406 during the extension and retraction of the electric telescopic rod 404, thereby realizing the adjustment of the inclination angle of the wind shield 405 and the wind shield cover 406.

[0073] Among them, two groups of air blowing mechanisms 400 are installed on both sides of the installation block 305 facing the sewage pool, thereby increasing the blowing intensity on the water surface of the sewage pool.

[0074] In the operation of the device of the above embodiment of the present invention, the lower opening of the air hole 402 is located above the liquid level of the sewage pool. After the fan 403 is started, the outside air is blown to the floating scum on the water surface of the sewage pool through the lower outlet of the air hole 402, and the inclination angle of the wind shield 405 and the wind shield sleeve 406 is adjusted by adjusting the telescopic length of the electric telescopic rod 404 to ensure that the blowing angle of the lower outlet of the air hole 402 can more efficiently blow the floating mud scum located in the middle of the sewage pool to the edge of the pool.

[0075] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
