[0006] A circular sewage pool;

[0007] A main shaft, the bottom of which is rotatably connected to the axis of the sewage tank via a rotating shaft;

[0008] a crossbeam, one end of which is fixed to the top of the main shaft, wherein the other end of the crossbeam extends above the side wall of the sewage tank;

[0009] A mud scraping component, wherein the mud scraping component is arranged on the outer side of the main shaft;

[0010] A bearing plate, the bearing plate is sleeved on the lower outer side of the main shaft;

[0011] A lifting assembly, which is disposed between the scraper component and the bearing plate and is used to drive the scraper component to move along the axial direction of the sewage tank;

[0012] A distance detection component is provided on the scraper component and is electrically connected to the lifting component to detect the distance between the scraper component and the bottom of the sewage pool;

[0013] The driving member is arranged at the other end of the crossbeam and is used to drive the crossbeam to perform circular motion along the circumference of the sewage pool with the main shaft as the rotation axis.

[0014] The beneficial effects of the utility model are:

[0015] 1) The device includes a distance detection component for real-time monitoring of the distance between the sludge scraping component and the bottom of the sewage tank, so as to determine the thickness of the sludge. Based on the distance data obtained by the distance detection component, the height of the sludge scraping component is automatically adjusted through the lifting component to keep proper contact with the surface of the sludge, so as to adapt to sludge with different thicknesses and effectively remove the sludge. At the same time, the cross beam is driven by the driving member to perform a circular motion, so that the sludge scraping component rotates circumferentially at the bottom of the sewage tank to ensure that the sludge is completely removed.

[0016] On the basis of the above technical solution, the utility model can also be improved as follows.

[0017] Further, a circular track is fixedly connected to the top of the sewage tank.

[0018] Further, the driving member includes a fixing plate in an inverted "U" shape, a roller adapted to the circular track, a servo motor, a chain, a first sprocket, and a second sprocket. The fixing plate is fixed to the bottom of the other end of the cross beam. Both sides of the roller are rotatably connected to the fixing plate through a rotating shaft. The servo motor is fixed to the top of the fixing plate, and the first sprocket is fixed to the driving end of the servo motor.

[0019] Further, the second sprocket is connected to the roller, and the chain is sleeved outside the first sprocket and the second sprocket.

[0020] The beneficial effect of adopting the above further solution is that the roller is driven to rotate by the driving end of the servo motor, so that the roller can roll on the circular track, and then the cross beam can be driven to perform a circular motion along the circumference of the sewage tank with the main shaft as the rotation axis.

[0021] Further, the sludge scraping component includes a suspension, a first suspension beam, a second suspension beam, and a plurality of scraping plates. The suspension slides outside the main shaft. The first suspension beam and the second suspension beam are respectively fixed to both sides of the suspension. A plurality of the scraping plates are linearly arrayed and fixed to the bottoms of the first suspension beam and the second suspension beam, and each scraping plate is inclined at the bottoms of the first suspension beam and the second suspension beam and forms an acute angle shape with the first suspension beam and the second suspension beam.

[0022] Further, the bottom of the sewage tank is conical, wherein the first suspension beam and the second suspension beam are respectively parallel to the taper of the bottom of the sewage tank.

[0023] The beneficial effect of adopting the above further solution is that since the scraping plates are arranged at the bottom of the cross beam and the cross beam drives the scraping plates to perform a circular motion in the sewage tank. Among them, the scraping plates are arranged in an acute angle shape on the first suspension beam and the second suspension beam, and the bottom of the sewage tank is conical, and the first suspension beam and the second suspension beam are respectively parallel to the taper of the bottom of the sewage tank. Therefore, the sludge scraped by the scraping plates gathers towards the axis of the sewage tank, which is convenient for centralized cleaning.

[0024] Furthermore, the lifting assembly is configured as a hydraulic cylinder.

[0025] Furthermore, the distance detection component is configured as a distance infrared sensor, and the distance infrared sensor is disposed on the scraper with the infrared optical axis facing the bottom of the sewage pool.

[0026] The beneficial effect of adopting the above further scheme is that, first, the distance between the scraper and the bottom of the sewage pool when there is no sludge settled is detected by the distance infrared sensor, and then, when sludge is settled in the sewage pool, the distance between the scraper and the bottom sludge is measured again by the distance infrared sensor. The thickness of the sludge can be known by the distance difference between the above two measurements. Therefore, based on the data of this distance difference, the hydraulic cylinder can be adjusted to drive the suspension to descend by a distance corresponding to the thickness of the sludge, so that the scraper is gradually lowered to an appropriate height from the sludge surface when scraping off the sludge, and then the height of the scraper can be adjusted according to the thickness of the sludge to scrape off all the sludge at the bottom of the sewage pool.

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] At present, in the field of sewage treatment, sedimentation method is often used to treat the silt in sewage. One common treatment method is to remove the sludge settled at the bottom of the sewage pool through a sludge scraping device at the bottom of the sewage pool.

[0035] However, there is a problem with the existing sludge scraping equipment, that is, the height of its sludge scraping parts is usually fixed and cannot be adjusted according to the thickness of the sludge. As a result, when the sludge is thick, the sludge scraping equipment often cannot completely remove the sludge and can only scrape off a part of the surface. In response to this, the utility model proposes a sewage desludge environmental protection treatment device to solve the above problem.

[0040] A crossbeam 30, one end of which is fixed to the top of the main shaft 20, wherein the other end of the crossbeam 30 extends above the side wall of the sewage tank 10;

[0041] A mud scraping component 40, which is disposed on the outer side of the main shaft 20;

[0042] A bearing plate 50, the bearing plate 50 is sleeved on the lower outer side of the main shaft 20;

[0043] A lifting assembly 60, which is disposed between the scraping member 40 and the bearing plate 50, and is used to drive the scraping member 40 to move along the axial direction of the sewage tank 10;

[0044] A distance detection assembly 70, which is disposed on the scraper component 40 and is electrically connected to the lifting assembly 60, and is used to detect the distance between the scraper component 40 and the bottom of the sewage pool 10;

[0045] A driving member 80, which is disposed at the other end of the crossbeam 30 and is used to drive the crossbeam 30 to perform a circular motion along the circumference of the sewage tank 10 with the main shaft 20 as the rotation axis;

[0046] The device includes a distance detection component 70 for monitoring the distance between the scraper component 40 and the bottom of the sewage pool 10 in real time, so as to determine the thickness of the sludge. Based on the distance data obtained by the distance detection component 70, the height of the scraper component 40 is automatically adjusted by the lifting component 60 so that it maintains proper contact with the surface of the sludge to adapt to sludge of different thicknesses, thereby effectively removing the sludge. At the same time, the driving member 80 drives the crossbeam 30 to perform circular motion, so that the scraper component 40 rotates circumferentially at the bottom of the sewage pool 10 to ensure that the sludge is completely removed.

[0047] In this embodiment, Figure 1-Figure 4As shown in the figure, a circular track 807 is fixedly connected to the top of the sewage tank 10. The driving member 80 includes a fixing plate 801 in an inverted "U" shape, a roller 802 adapted to the circular track 807, a servo motor 803, a chain 804, a first sprocket 805, and a second sprocket 806. The fixing plate 801 is fixed to the bottom of the other end of the cross beam 30. Both sides of the roller 802 are rotatably connected to the fixing plate 801 through a rotating shaft. The servo motor 803 is fixed to the top of the fixing plate 801. The first sprocket 805 is fixed to the driving end of the servo motor 803. The second sprocket 806 is connected to the roller 802. The chain 804 is sleeved outside the first sprocket 805 and the second sprocket 806;

[0048] The driving end of the servo motor 803 drives the roller 802 to rotate, so that the roller 802 can roll on the circular track 807, and then the cross beam 30 can be driven to make a circular motion along the circumferential direction of the sewage tank 10 with the main shaft 20 as the rotation axis.

[0049] In this embodiment, as Figure 1-Figure 4 shown, the sludge scraping member 40 includes a suspension, a first suspension beam 401, a second suspension beam 402, and a plurality of scraping plates 403. The suspension slides outside the main shaft 20. The first suspension beam 401 and the second suspension beam 402 are respectively fixed to both sides of the suspension. A plurality of scraping plates 403 are linearly arrayed and fixed to the bottom of the first suspension beam 401 and the bottom of the second suspension beam 402. Each scraping plate 403 is inclined at the bottom of the first suspension beam 401 and the bottom of the second suspension beam 402, and forms an acute angle shape with the first suspension beam 401 and the second suspension beam 402. The bottom of the sewage tank 10 is in a conical shape. Among them, the first suspension beam 401 and the second suspension beam 402 are respectively parallel to the taper of the bottom of the sewage tank 10;

[0050] Since the scraping plate 403 is arranged at the bottom of the cross beam 30, the cross beam 30 drives the scraping plate 403 to make a circular motion in the sewage tank 10. Among them, the scraping plate 403 is arranged in an acute angle shape on the first suspension beam 401 and the second suspension beam 402, and the bottom of the sewage tank 10 is in a conical shape, and the first suspension beam 401 and the second suspension beam 402 are respectively parallel to the taper of the bottom of the sewage tank 10. Therefore, the sludge scraped by the scraping plate 403 naturally gathers towards the axis of the sewage tank 10, which is convenient for centralized cleaning and improves the efficiency of sewage treatment.

[0051] In this embodiment, as Figure 1-Figure 4As shown, the lifting component 60 is configured as a hydraulic cylinder, the distance detection component 70 is configured as a distance infrared sensor, and the distance infrared sensor is arranged on the scraper 403 with the infrared optical axis facing the bottom of the sewage pool 10. First, the distance between the scraper 403 and the bottom of the sewage pool 10 when there is no sludge settled is detected by the distance infrared sensor. Then, when sludge is settled in the sewage pool 10, the distance between the scraper 403 and the bottom sludge is measured again by the distance infrared sensor. The thickness of the sludge can be known by the distance difference between the above two measurements. Therefore, based on the data of this distance difference, the hydraulic cylinder can be adjusted to drive the suspension to descend by a distance corresponding to the thickness of the sludge, so that the scraper 403 is gradually lowered to an appropriate height of the sludge surface when scraping the sludge, and then the height of the scraper 403 can be adjusted according to the thickness of the sludge to scrape off all the sludge at the bottom of the sewage pool 10.

[0052] The specific working process of the utility model is as follows:

[0053] (1) Measure the thickness of the sludge

[0054] First, the distance between the scraper 403 and the bottom of the sewage pool 10 when there is no sludge settled is detected by the distance infrared sensor. Then, when sludge is settled in the sewage pool 10, the distance between the scraper 403 and the bottom sludge is measured again by the distance difference between the above two measurements, the thickness of the sludge can be known.

[0055] (2) Scrape off the sludge

[0056] The roller 802 is driven to rotate by the driving end of the servo motor 803, so that the roller 802 can roll on the circular track 807, and then the beam 30 can be driven to make a circular motion along the circumference of the sewage pool 10 with the main shaft 20 as the rotation axis. Since the scraper 403 is arranged at the bottom of the beam 30, the beam 30 drives the scraper 403 to make a circular motion in the sewage pool 10, wherein the scraper 403 is arranged at an acute angle on the suspension beam 1 401 and the suspension beam 2 402, and the bottom of the sewage pool 10 is conical, and the suspension beam 1 401 and the suspension beam 2 402 are respectively parallel to the taper of the bottom of the sewage pool 10, therefore, the sludge scraped by the scraper 403 naturally gathers toward the axis of the sewage pool 10.

[0057] (3) Adjust the scraper 403 downward according to the thickness of the sludge

[0058] At this moment, the suspension is driven down by the hydraulic cylinder to a distance corresponding to the thickness of the sludge, so that the scraper 403 is gradually lowered to an appropriate height on the sludge surface when scraping the sludge. Then, the height of the scraper 403 can be adjusted according to the thickness of the sludge to scrape off all the sludge at the bottom of the sewage pool 10.
