Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment sludge removal device. 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, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] According to the specification of the Chinese Utility Model Publication No. "CN221964666U", "a sludge removal device for sewage treatment, when using this device, sewage is introduced into the inlet and the sewage falls directly onto the filter screen conveying mechanism. Water is left through the filter holes, while impurities remain on the surface of the filter screen conveying mechanism and are carried to the outside of the passage trough by the rotating filter screen conveying mechanism. The impurities fall down due to their own gravity, which can filter and clean the impurities in the sewage and reduce the situation of impurities clogging the filter holes."

[0004] According to the aforementioned patent, existing sewage treatment sludge removal devices require surface cleaning to prevent clogging of the filter conveying mechanism during use. However, the cleaning effect of these devices is poor, affecting cleaning efficiency. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0026] Given the current technology, existing sewage treatment sludge removal devices require surface cleaning to prevent clogging of the filter conveying mechanism during use. However, the cleaning effect of these devices is poor, affecting cleaning efficiency.

[0027] like Figure 1-4As shown, this utility model embodiment provides a sewage treatment sludge removal device, including a cleaning component 1: the cleaning component 1 includes: a collection frame 111 disposed on the outside of a sewage treatment tank 11; a fixing plate 12 symmetrically disposed on the sewage treatment tank 11; a filter conveying mechanism 13 disposed on the inside of the sewage treatment tank 11; a motor 14 disposed on the fixing plate 12; a rectangular block 141 disposed on the output end of the motor 14; screws 15 symmetrically disposed on the fixing plate 12; and nuts 151. A plate 16 is located on the outer side of the screw 15 and threadedly connected to the screw 15; a rod 17 is located on the plate 16 and passes through the fixing plate 12; a roller brush 18 is located on the inner side of the two sets of fixing plates 12; a rectangular groove 181 is formed on the roller brush 18 and docks with the rectangular block 141; a slot 182 is formed on the roller brush 18 and docks with the rod 17; and scrapers 19 are symmetrically arranged on the inner side of the two sets of fixing plates 12.

[0028] When cleaning sludge from wastewater, the wastewater is first transported into the wastewater treatment tank 11 through the inlet at the top of the tank. Then, the wastewater is filtered by the filter conveyor mechanism 13, causing sludge to adhere to its surface. As the filter conveyor mechanism 13 moves, the perforated conveyor belt on its surface is cleaned by the scraper 19 in contact with it. Then, the motor 14 is started by an external power source, causing the rectangular block 141 to rotate. Since the rectangular block 141 engages with the rectangular groove 181 on the roller brush 18, the roller brush 18 rotates, further cleaning the surface of the filter conveyor mechanism 13. The sludge and debris that fall off will fall into the collection box 111 for subsequent processing. When the roller brush 18 needs to be replaced, the nut 151 can be turned and screwed to the output end of the screw 15 to release the limiting position on the plate 16, so that the insert rod 17 can be pulled out from the inside of the slot 182. This releases the fixation on the roller brush 18. Then, the roller brush 18 is pulled to separate the rectangular block 141 from the rectangular slot 181, so that the roller brush 18 can be disassembled for subsequent periodic replacement. The device has a simple structure, which facilitates the cleaning of the filter conveying mechanism 13 and the replacement of the roller brush 18, effectively improving the cleaning efficiency.

[0029] Furthermore, the filter conveying mechanism 13 is a conveyor, and the filter belt surface has filter holes to achieve the effect of filtering sewage and sludge. This solution is existing technology and will not be described in detail here.

[0030] Furthermore, an auxiliary component 2 is provided on the screw 15, the auxiliary component 2 including a spring 21 sleeved on the outside of the screw 15.

[0031] A spring 21 is fitted on the outer wall of the screw 15. When the screw 151 is rotated to release the limit on the plate 16, the spring 21 can hold the plate 16 in place, thus limiting the plate 16 and preventing the insertion rod 17 from moving when installing the roller brush 18, which would affect the installation of the roller brush 18 and make it more convenient to use.

[0032] Furthermore, the auxiliary component 2 also includes a cone 22 disposed on the insertion rod 17.

[0033] A cone 22 is provided at one end of the insertion rod 17. When the insertion rod 17 is connected to the slot 182, the shape of the cone 22 makes it easier for the insertion rod 17 to connect with the slot 182, making it more convenient to use.

[0034] Furthermore, the auxiliary component 2 also includes a stop 23 disposed on the screw 15.

[0035] A stop 23 is provided at one end of the screw 15 to prevent the nut 151 from separating from the screw 15 due to operational errors, thereby increasing the structural stability of the device and making it more convenient to use.

[0036] Furthermore, the stop block 23 and the screw 15 are threadedly connected.

[0037] The stop block 23 and the screw 15 are connected by a thread, so that the stop block 23 can be removed from one end of the screw 15 by screwing. This way, the nut 151 and the plate 16 do not have a limiting mechanism, so that they can be replaced.

[0038] Furthermore, the scraper 19 is connected to the fixing plate 12 by bolts.

[0039] The scraper 19 is bolted to the fixing plate 12, which makes it easy to remove the scraper 19 later so that the damaged scraper 19 can be replaced, making it more convenient to use.

[0040] Furthermore, the auxiliary component 2 also includes grooves 24 symmetrically formed on the fixing plate 12.

[0041] A symmetrical groove 24 is provided on one side of the fixing plate 12 so that when the scraper 19 is installed, the scraper 19 aligns with the groove 24, which limits the position of the scraper 19 and facilitates its subsequent fixing.

[0042] Furthermore, the auxiliary component 2 also includes rubber pads 25 symmetrically arranged inside the rectangular groove 181.

[0043] Rubber pads 25 are symmetrically arranged on opposite sides of the inner side of the rectangular groove 181. This increases friction and makes the docking of the rectangular groove 181 and the rectangular block 141 more stable.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
