Description

Technical Field

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

[0002] Floating sludge in sewage treatment tanks refers to the phenomenon in which, due to various reasons, sludge or solid matter fails to settle effectively during the sewage treatment process, instead floating on the surface of the tank water or suspended in the water. This floating sludge is typically composed of sludge, grease, foam, suspended particles, and other impurities. The presence of floating sludge not only affects sewage treatment effectiveness but can also adversely affect subsequent treatment processes and equipment, such as clogging pipes and affecting pump performance. Therefore, a sewage treatment tank floating sludge collection device is installed to salvage and remove floating sludge from the sewage tank, promptly removing any accumulated floating sludge to ensure normal system operation.

[0003] After searching, the Chinese patent application number 202022729912.6 discloses a device for collecting floating sludge in a sewage treatment pool, comprising a rotating shaft, a driving disc sleeved on the surface of the rotating shaft, a transmission belt movably connected to the interior of the driving disc, a driven disc movably connected to the interior of the transmission belt, a driven shaft sleeved on the inner wall of the driven disc, a brush shaft fixedly connected to one end of the driven shaft, a cross bar sleeved on the surface of the driven shaft, a chute provided at the bottom of the cross bar, a slider slidably connected to the interior of the chute. The device for collecting floating sludge in a sewage treatment pool, through the connection between the rotating shaft and the driving disc, drives the driving disc to rotate while the rotating shaft rotates, and combined with the connection between the driving disc and the transmission belt, can drive the driven disc to move, thereby driving the brush shaft to move, and can scrub the walls of the sewage pool in the process of collecting floating sludge, thereby improving the cleanliness.

[0004] The above patent still has the following deficiencies: (1) It is not convenient to collect the floating sludge. In the process of using the existing device, the filter plate is usually directly removed to collect the floating sludge on the surface. However, since the device is immersed in the sewage pool for a long time, the floating sludge intercepted by the device is easy to clog the holes on the surface of the filter plate, affecting the filtering effect of the filter plate. At the same time, the floating sludge is easy to be swept directly by the filter plate along with the sewage, making it inconvenient for the device to continuously collect the floating sludge for a long time.

[0005] (2) It is inconvenient to collect the floating mud residue on the pool wall. Since there is a large gap between the device and the sewage pool wall during use, when the device cleans the floating mud residue on the pool wall, a large amount of floating mud residue is discharged from the gap between the pool wall and the device, reducing the collection effect of the device.

[0006] Therefore, there is an urgent need for a sewage treatment pool floating sludge collection device to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to address the current defect that it is inconvenient to collect floating mud residue. In the existing device, the filter plate is usually directly removed to collect the floating mud residue on the surface during use. However, since the device is immersed in the sewage pool for a long time, the floating mud residue intercepted by the device is easy to clog the holes on the surface of the filter plate, affecting the filtering effect of the filter plate. At the same time, the floating mud residue is easy to be directly swept over the filter plate along with the sewage, resulting in the device being inconvenient to continuously collect the floating mud residue for a long time.

[0019] Through the above technical solution, the sludge tank is pushed up and down by the hydraulic push rod to clean the floating sludge on the surface of the metal filter.

[0020] As the preferred technical solution of the present application, the guide structure includes a pipe rack fixed on both sides of the bottom end of the beam, a second baffle rotatably connected to the outside of the pipe rack, a movable groove opened inside the pipe rack, a fixing bolt fixed inside the movable groove, a movable groove fixed on one side of the fixing bolt, a scraper fixed on one side of the movable groove, and a telescopic spring installed on one side of the first baffle and connected to the pipe rack.

[0021] With the above technical solution, the telescopic spring pulls the first baffle to flip, so that the second baffle and the first baffle intercept and guide the floating mud residue at the pool wall, so that the floating mud residue contacts the metal filter screen for interception and concentration.

[0022] As a preferred technical solution of the present application, a rotating structure is formed between the first baffle and the pipe rack, and a sliding structure is formed between the second baffle and the first baffle.

[0023] With the above technical solution, the first baffle is pulled by the stretched telescopic spring to flip around the pipe rack to both sides, so that the scraper contacts the pool wall.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0035] like Figure 1-5 As shown, the present embodiment proposes a device for collecting floating sludge in a sewage treatment pool, comprising a beam 1 and further comprising:

[0036] The connecting frame 3 is fixed on both sides of the top of the beam 1;

[0037] The mounting frame 7 is mounted on the bottom end of the beam 1, and a fixing frame 6 is installed inside the mounting frame 7, and a metal filter 5 is fixed inside the fixing frame 6;

[0038] The guide structure 4 is provided on both sides of the bottom end of the crossbeam 1 and is used to guide the floating mud residue at the pool wall;

[0039] The recovery structure 2 is arranged at the bottom end of the beam 1, wherein the recovery structure 2 includes a hydraulic push rod 201 installed at the top of the beam 1, a sludge trough 202 installed at the bottom end of the hydraulic push rod 201, a scraper 205 installed on one side of the sludge trough 202, and a discharge assembly installed inside the sludge trough 202.

[0040] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the discharge component includes a spiral blade shaft 203 rotatably connected to the inside of the sludge tank 202, a transmission motor 206 installed on one side of the sludge tank 202 and the rotating end connected to the spiral blade shaft 203, a sealing cover 207 fixed on the outside of the transmission motor 206, a folding tube 209 connected to the top of one side of the sludge tank 202, a connecting tube 204 fixed on the outside of the folding tube 209, and a fixing frame 208 installed on the outside of the connecting tube 204 and connected to the crossbeam 1, the folding tube 209 is in the shape of a hollow tubular structure with a wrinkled surface, and the folding tube 209 is a retractable structure, the connecting tube 204 is connected to the sludge tank 202 through the folding tube 209, and the hydraulic push rod 201 is in the sludge tank 202. The hydraulic push rod 201 passes through the crossbeam 1 and is connected to the sludge tank 202. When too much floating sludge is accumulated on the surface of the metal filter 5, the hydraulic push rod 201 is started to extend, so that the hydraulic push rod 201 pushes the sludge tank 202 downward, so that the floating sludge enters the interior of the sludge tank 202. At the same time, the scraper 205 cleans and scrapes the floating sludge on the surface of the metal filter 5. The transmission motor 206 is started to drive the spiral blade shaft 203 to rotate, so that the spiral blade shaft 203 pushes the floating sludge to one side of the sludge tank 202 during the rotation. The connecting pipe 204 is connected to the sewage tank sludge pump. The sludge pump can suck out the floating sludge accumulated inside the sludge tank 202 through the connecting pipe 204 and the folding pipe 209, so as to facilitate centralized treatment of the floating sludge.

[0041] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the guide structure 4 includes a pipe rack 405 fixed on both sides of the bottom end of the crossbeam 1, a second baffle 404 rotatably connected to the outside of the pipe rack 405, a movable groove 403 opened in the pipe rack 405, a fixing bolt 402 fixed in the movable groove 403, a movable groove 403 fixed on one side of the fixing bolt 402, a scraper 407 fixed on one side of the movable groove 403, and a telescopic spring 406 installed on one side of the first baffle 401 and connected to the pipe rack 405. A rotating structure is formed between the first baffle 401 and the pipe rack 405, and a sliding structure is formed between the second baffle 404 and the first baffle 401. After the device is placed in the sewage, the first baffle 401 is pulled to flip to both sides around the pipe rack 405 by the extended telescopic spring 406, so that the scraper 407 contacts the pool wall. When the device moves in the sewage, the second baffle 404 and the first baffle 401 intercept and guide the floating mud residue at the pool wall, so that the floating mud residue contacts the metal filter 5 for filtration and concentration. By pulling the second baffle 404 to slide on one side of the first baffle 401, the width of the device can be adjusted according to the width of the sewage pool, so that the fixing bolt 402 can be locked and fixed in the position between the second baffle 404 and the first baffle 401. The scraper 407 can scrape the floating mud residue attached to the pool wall surface during movement.

[0042] Specifically, when the present sewage treatment pool floating sludge collection device is in use: by connecting the connecting frame 3 to the sewage pool rail carriage, placing the metal filter screen 5 in the sewage, and driving the device in the sewage pool by the rail carriage, the metal filter screen 5 intercepts and filters the floating sludge in the sewage, and at the same time, a large amount of floating sludge accumulates on the surface of the metal filter screen 5. The sludge pump is connected to the recovery structure 2, and the floating sludge on the surface of the metal filter screen 5 can be cleaned through the recovery structure 2, and the floating sludge is blocked by the guide structure 4 and discharged from the gap between the device and the pool wall.

[0043] When too much floating sludge accumulates on the surface of the metal filter 5, the hydraulic push rod 201 is activated to extend, so that the hydraulic push rod 201 pushes the sludge tank 202 downward, so that the floating sludge enters the interior of the sludge tank 202. At the same time, the scraper 205 cleans and scrapes the floating sludge on the surface of the metal filter 5. The transmission motor 206 is started to drive the spiral blade shaft 203 to rotate, so that the spiral blade shaft 203 pushes the floating sludge to one side of the sludge tank 202 during the rotation. The connecting pipe 204 is connected to the sewage tank sludge pump. The sludge pump can suck out the floating sludge accumulated in the sludge tank 202 through the connecting pipe 204 and the folding pipe 209, so as to facilitate the centralized treatment of the floating sludge.

[0044] After the device is placed in the sewage, the first baffle 401 is pulled to flip to both sides around the pipe rack 405 by the extended telescopic spring 406, so that the scraper 407 contacts the pool wall. When the device moves in the sewage, the second baffle 404 and the first baffle 401 intercept and guide the floating mud residue at the pool wall, so that the floating mud residue contacts the metal filter 5 for interception, and the floating mud residue is concentrated. By pulling the second baffle 404 to slide on one side of the first baffle 401, the width of the device can be adjusted according to the width of the sewage pool, so that the fixing bolt 402 can be locked and fixed in place between the second baffle 404 and the first baffle 401. The scraper 407 can scrape the floating mud residue attached to the pool wall surface during the movement of the sewage pool track.
