Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device with anti-clogging function. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, and catering.

[0003] In the prior art, patent publication number CN202320573079.1 discloses a sewage treatment device with anti-clogging function, including a purification tank, a stable support, a filter bucket, a gravel filter hole, a filter umbrella, a silt filter hole, an inlet pipe, an outlet pipe, a stirring rod, a drive motor, an anti-stacking scraper, a drive box, a cleaning shaft, and a cleaning roller brush. The stable support is fixed to the outer side of the lower end of the purification tank, the filter bucket is fixed to the inner side of the upper end of the purification tank, the gravel filter hole is located on the side wall of the filter bucket and passes through the side wall of the filter bucket, and the filter umbrella is located inside the purification tank and below the filter bucket.

[0004] The above-mentioned sewage treatment device has problems in actual use. For example, stubborn dirt easily adheres to the upper side of the gravel filter holes. The anti-stacking scraper can only scrape horizontally. When the dirt is not scraped off in one go, the stubborn dirt is flattened by the anti-stacking scraper and will block the gravel filter holes, affecting the subsequent sewage filtration operation. In order to address these issues, we propose a sewage treatment device with anti-clogging function. Utility Model Content

When the sewage treatment device needs to be used, the outlet pipe 13 can be connected to the external equipment, then the inlet 12 can be connected to the external auxiliary material adding equipment, and then the two outlets of the outlet pipe 10 can be connected to the external garbage treatment equipment. At this time, the sewage is discharged into the interior of the treatment tank 1 through the sewage inlet pipe 14. At this time, the control switch group 18 can be adjusted, the motor 15 can be turned, the output end of the motor 15 can be fixed, and then the vertical rotating rod 4 can be rotated.

[0028] The top anti-blocking mechanism 5 includes limiting cylinders 55, fixing rods 56, and limiting grooves 59. The limiting cylinders 55 are evenly arranged on the upper surface of the cover plate 2. The fixing rods 56 are slidably connected inside the three limiting cylinders 55 respectively. An upper bucket-shaped filter screen 6 (the upper bucket-shaped filter screen 6 can be a stainless steel filter screen) is fixedly connected to the lower end of the three fixing rods 56. The outer arc surface of the upper bucket-shaped filter screen 6 is fixedly connected to evenly distributed limiting blocks. The upper side of the inner arc surface of the treatment tank 1 is provided with evenly distributed limiting grooves 59. The interior of the three limiting grooves 59 is slidably connected to the outer surface of the limiting blocks located in the same position. The top anti-blocking mechanism 5 also includes a fixing block 51, a transverse rotating rod 52, a first crank rod 53, a second crank rod 54, and a third crank rod 55. A bevel gear 57 and a second bevel gear 58 are provided. The upper surface of the cover plate 2 is provided with evenly distributed fixing blocks 51. The middle portions of the three fixing blocks 51 are rotatably connected to transverse rotating rods 52. The ends of the three transverse rotating rods 52 furthest from the center of the processing tank 1 are respectively fixedly connected to first crank rods 53. The ends of the three first crank rods 53 are rotatably connected to second crank rods 54. The ends of the three second crank rods 54 are respectively fixedly connected to the upper ends of fixing rods 56 located at the same position. The ends of the three transverse rotating rods 52 closest to the center of the processing tank 1 are respectively fixedly connected to second bevel gears 58. A first bevel gear 57 is fixedly sleeved on the upper side of the outer arc surface of the vertical rotating rod 4. The three second bevel gears 58 are respectively meshed with one of the first bevel gears 57. A guide tube 7 is provided on the lower side of the middle part of the bucket-shaped filter screen 6, and a discharge pipe 10 is provided in the middle of the treatment tank 1. The guide tube 7 extends into the interior of the discharge pipe 10. An evenly distributed upper scraper 8 is provided on the upper side of the outer arc surface of the vertical rotating rod 4. The middle part of the discharge pipe 10 is rotatably connected to the middle part of the outer arc surface of the vertical rotating rod 4. During this period, the first bevel gear 57 can be driven to rotate, which in turn drives the second bevel gear 58 to rotate. The first bevel gear 57 then drives the transverse rotating rod 52 to rotate, which in turn drives the end of the first crank rod 53 to rotate around the central axis of the transverse rotating rod 52. Whenever the end of the first crank rod 53 rotates to the uppermost position, the second crank rod 54 pulls the fixed rod 56 upward, so that the three fixed rods 56 simultaneously... The upward movement causes the upper bucket-shaped filter screen 6 to move upward. Whenever the end of the first crank rod 53 rotates to the lowest side, it will push the fixing rod 56 downward through the second crank rod 54, causing the three fixing rods 56 to move downward simultaneously, causing the upper bucket-shaped filter screen 6 to move downward. As the upper bucket-shaped filter screen 6 moves up and down continuously, during this period, the rotation of the vertical rotating rod 4 will drive the three upper scrapers 8 to rotate. When the upper bucket-shaped filter screen 6 moves to the uppermost side, the upper scrapers 8 will rotate rapidly and scrape the upper surface of the upper bucket-shaped filter screen 6, causing the dirt adhering to its surface to be scraped and loosened. Under the action of gravity, it enters the guide tube 7 and is then discharged through the discharge pipe 10 to the external waste treatment equipment for processing.

[0029] Lower anti-clogging mechanism 9: Located inside the lower side of the treatment tank 1, the lower anti-clogging mechanism 9 includes a fixing ring 91, a lower funnel-shaped filter screen 92, scrapers 93, scrapers 94, a sludge discharge pipe 95, and a butterfly valve 96. The fixing ring 91 is fixedly connected to the lower side of the inner arc surface of the treatment tank 1. The lower funnel-shaped filter screen 92 is located in the middle of the fixing ring 91. The lower side of the outer arc surface of the vertical rotating rod 4 is provided with evenly distributed scrapers 93. The ends of the three scrapers 93 are respectively fixedly connected to scrapers 94. The front side of the outer arc surface of the treatment tank 1 is provided with a sludge discharge pipe 95. A butterfly valve 96 is connected in series in the middle of the sludge discharge pipe 95. The preliminarily filtered wastewater moves downward. At this time, the external auxiliary material addition equipment can be adjusted to continuously add flocculant into the interior of the treatment tank 1. This flocculant will react with the wastewater. During this period, the mixture is stirred. The stirring rod 11 agitates the wastewater to accelerate the reaction. At this time, the wastewater reacts with the flocculant to produce sediment. This sediment is filtered by the lower funnel-shaped filter screen 92. The treated wastewater enters the lower side of the lower funnel-shaped filter screen 92. At this time, the control switch group 18 can be adjusted and the solenoid valve is opened. The treated wastewater is discharged to the outside of the treatment tank 1 through the outlet pipe 13. The sediment remains on the upper surface of the lower funnel-shaped filter screen 92. With the rotation of the scraper 93, the sediment is brushed away. The sediment on the surface of the lower funnel-shaped filter screen 92 falls into the upper side of the fixing ring 91. After the work is completed, some wastewater will remain in the sludge on the upper side of the fixing ring 91. At this time, the butterfly valve 96 can be opened. The sludge can then be discharged to the outside of the device through the sludge outlet pipe 95, completing the wastewater treatment operation.

[0030] The working principle of the sewage treatment device with anti-clogging function provided by this utility model is as follows: When the sewage treatment device is needed, the outlet pipe 13 can be connected to the external equipment, then the inlet 12 can be connected to the external auxiliary material adding equipment, and the two outlets of the outlet pipe 10 can be connected to the external garbage treatment equipment. At this time, the sewage is discharged into the treatment tank 1 through the sewage inlet pipe 14. At this time, the control switch group 18 can be adjusted, the motor 15 can be turned, the output end of the motor 15 can be fixed, and then the vertical rotating rod 4 can be rotated. During this period, the first bevel gear 57 can be rotated, and then the second bevel gear 58 can be rotated. This, in turn, drives the transverse rotating rod 52 to rotate via the first bevel gear 57, which in turn drives the end of the first crank rod 53 to rotate around the central axis of the transverse rotating rod 52. Whenever the end of the first crank rod 53 reaches its uppermost position, it pulls the fixed rod 56 upward via the second crank rod 54, causing all three fixed rods 56 to move upward simultaneously, thus moving the upper funnel-shaped filter screen 6 upward. Whenever the end of the first crank rod 53 reaches its lowermost position, it pushes the fixed rod 56 downward via the second crank rod 54, causing all three fixed rods 56 to move downward simultaneously, thus moving the upper funnel-shaped filter screen 6 downward. As the upper funnel-shaped filter screen 6 continuously moves up and down, and during this process... The rotation of the vertical rotating rod 4 drives the three upper scrapers 8 to rotate. When the upper funnel-shaped filter screen 6 moves to the top, the upper scrapers 8 rotate rapidly and scrape the upper surface of the upper funnel-shaped filter screen 6, causing the dirt adhering to its surface to be scraped and loosened. Under the action of gravity, it enters the guide pipe 7 and is then discharged through the discharge pipe 10 to the external waste treatment equipment for processing. This pre-filtered wastewater moves downwards, at which point the external auxiliary material addition equipment can be adjusted to continuously add flocculant into the treatment tank 1. This flocculant will react with the wastewater. During this period, the stirring rod 11 agitates the wastewater to accelerate the reaction. At this time, the wastewater reacts with the flocculant to produce sediment. The sediment will be filtered by the lower funnel-shaped filter screen 92. The treated wastewater will enter the lower side of the lower funnel-shaped filter screen 92. At this time, the control switch group 18 can be adjusted and the solenoid valve will open. The treated wastewater will be discharged to the outside of the treatment tank 1 through the outlet pipe 13. The sediment will remain on the upper surface of the lower funnel-shaped filter screen 92. As the scraper 93 rotates, it will brush the sediment. The sediment on the surface of the lower funnel-shaped filter screen 92 will fall into the upper side of the fixing ring 91. After the work is completed, some wastewater will remain in the sludge on the upper side of the fixing ring 91. At this time, the butterfly valve 96 can be opened. The sludge will be discharged to the outside of the device through the sludge outlet pipe 95, completing the wastewater treatment operation.

[0031] It is worth noting that the butterfly valve 96, solenoid valve and motor 15 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended to use a DN100 model turbine manual flange butterfly valve for butterfly valve 96, a ZCSDF model cast iron diaphragm solenoid valve for solenoid valve, and a B5 type continuously variable motor for motor 15. The control switch group 18 is equipped with control buttons that correspond one-to-one with the solenoid valve and motor 15 and are used to control their switching.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
