Description

Technical Field

[0001] This utility model relates to the field of sludge cleaning technology, specifically to a device for cleaning sludge from sewage treatment ponds. Background Technology

[0002] During the wastewater treatment process, a large amount of dirt will be deposited in the wastewater treatment tank due to the sedimentation treatment of wastewater. The sludge will continue to accumulate in the wastewater treatment tank, occupying the effective volume and reducing the wastewater treatment space, thereby reducing the efficiency of wastewater treatment. At the same time, the sludge contains a large amount of organic matter, microorganisms and nutrients. If it is not cleaned in time, these substances may redissolve or be released into the wastewater, leading to the deterioration of the effluent quality.

[0003] In order to make better use of the sewage treatment pond, it is necessary to clean it regularly, which requires the use of equipment for cleaning sludge from the sewage treatment pond.

[0004] Existing equipment for cleaning sludge from wastewater treatment ponds has a single sludge adsorption location, which cannot adsorb sludge from all directions. This easily creates cleaning blind spots in the wastewater treatment pond, resulting in some sludge residue and affecting the overall cleaning effect. It is not effective enough for cleaning sludge on the inner wall of the wastewater treatment pond. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a device for cleaning sludge from sewage treatment ponds.

[0006] The technical solution of this utility model is: a device for cleaning sludge from a sewage treatment pond, comprising a sewage treatment pond, a support mounting frame disposed at the upper end of the sewage treatment pond and movable back and forth along the sewage treatment pond, a scraper plate connected to the bottom end of the support mounting frame, and a sludge cleaning component disposed on the scraper plate.

[0007] The sludge cleaning assembly includes a sludge collection box located at the upper end of the support mounting frame, a sludge suction box connected to the bottom end of the support mounting frame via a connecting column, a linkage vertical plate slidably connected to the front and rear sides of the scraper, multiple folded sludge suction pipes located on the side wall of the sludge suction box, and a sludge suction head located at the bottom end of each folded sludge suction pipe. The upper end of the scraper is provided with a connecting horizontal plate connected to each of the linkage vertical plates via an electric telescopic rod. The side wall of the linkage vertical plate is provided with multiple fixing rings for fixing the bottom ends of each folded sludge suction pipe. The sludge collection box and the sludge suction box are connected by a connecting pipe, and a sludge pump is provided at the connection point.

[0008] Furthermore, the upper left and right sides of the sewage treatment tank are respectively provided with sliding adjustment grooves along its width direction, and the support mounting frame includes a mounting horizontal plate, support vertical rods provided on the left and right sides of the bottom end of the mounting horizontal plate, and a first hydraulic cylinder that drives the support vertical rods to slide back and forth in the corresponding sliding adjustment grooves.

[0009] Explanation: When it is necessary to move the scraper back and forth in the sewage treatment tank as needed, the first hydraulic cylinder drives the support vertical rod to move back and forth in the corresponding sliding adjustment groove, while the mounting horizontal plate and scraper move synchronously, thereby achieving the purpose of scraping and cleaning the sludge inside the sewage treatment tank. It can accurately cover the area that needs to be cleaned and improve cleaning efficiency.

[0010] Furthermore, the scraper blade includes a middle scraper blade with mounting recesses on both the left and right sides, a second hydraulic cylinder disposed within the mounting recesses, and side scraper blades disposed on the left and right sides of the middle scraper blade with one end extending into the corresponding mounting recesses and connected to the second hydraulic cylinder.

[0011] Note: When in use, the width of the scraper can be adjusted according to the size of the sewage treatment tank. Specifically, it is driven by two second hydraulic cylinders to move the side scrapers located on both sides. When the side scrapers slide outward from the mounting recess, the overall width of the scraper increases; when the side scrapers slide inward from the mounting recess, the overall width of the scraper decreases. The adjustable width of the scraper allows it to flexibly meet the special needs of sewage treatment tanks of different sizes, better adapt to changes in the internal structure of the sewage treatment tank, and improve the versatility of the equipment.

[0012] Furthermore, scraper strips are provided at the bottom end of the side scraper and on the side wall near the sewage treatment tank.

[0013] Note: The scraper can more thoroughly scrape and clean the sludge in the sewage treatment tank, improving the sludge cleaning effect.

[0014] Furthermore, the scraper is a detachable structure.

[0015] Note: The scraper is designed to be detachable, which makes it easy to replace or clean it in a timely manner, ensuring the scraping effect of the scraper (36) and improving the overall sludge cleaning effect of the equipment.

[0016] The beneficial effects of this utility model are:

[0017] This utility model discloses a device for cleaning sludge from sewage treatment ponds. In use, a scraper blade scrapes and collects the sludge from the inner wall of the sewage treatment pond. The collected sludge is then pumped into a suction tank via a folded suction pipe by a sludge cleaning component. Finally, a sludge pump removes the temporarily stored sludge from the suction tank, facilitating subsequent sludge treatment and disposal. The entire cleaning process is automated, reducing the need for manual operation and improving work efficiency and safety. Furthermore, the sludge cleaning component can adsorb sludge from all directions through the folded suction pipes, improving the thoroughness of sludge cleaning. The scraper blade's width can be adjusted according to the size of the sewage treatment pond, allowing it to flexibly meet the special needs of sewage treatment ponds of different sizes and better adapt to changes in the internal structure of the pond, thus improving the equipment's versatility.

Detailed Implementation

[0023] Example 1: As Figure 1 As shown, a device for cleaning sludge from a sewage treatment pond includes a sewage treatment pond 1, a support mounting frame 2 located at the upper end of the sewage treatment pond 1 and movable back and forth along the sewage treatment pond 1, a scraper 3 connected to the bottom end of the support mounting frame 2, and a sludge cleaning assembly 4 located on the scraper 3.

[0024] like Figure 3As shown, the upper left and right sides of the sewage treatment tank 1 are respectively provided with sliding adjustment grooves 10 along its width direction. The support mounting frame 2 includes a mounting horizontal plate 20, support vertical rods 21 provided on the left and right sides of the bottom end of the mounting horizontal plate 20, and a first hydraulic cylinder 22 that drives the support vertical rods 21 to slide back and forth in the corresponding sliding adjustment grooves 10. When it is necessary to move the scraper 3 back and forth in the sewage treatment tank 1 as needed, the first hydraulic cylinder 22 drives the support vertical rods 21 to move back and forth in the corresponding sliding adjustment grooves 10, and the mounting horizontal plate 20 and the scraper 3 move synchronously, so as to achieve the purpose of scraping and cleaning the sludge inside the sewage treatment tank 1, which can accurately cover the area where the sludge needs to be cleaned and improve the cleaning efficiency. The first hydraulic cylinder 22 adopts existing technology, such as a hydraulic cylinder of model K20-50-25.

[0025] like Figure 4 As shown, the scraper 3 includes a middle scraper 33 with mounting recesses 330 on both the left and right sides, a second hydraulic cylinder 34 located in the mounting recesses 330, and side scrapers 35 located on the left and right sides of the middle scraper 33 with one end extending into the corresponding mounting recesses 330 and connected to the second hydraulic cylinder 34. When in use, the width of the scraper 3 can be adjusted according to the size of the sewage treatment tank 1. Specifically, the two second hydraulic cylinders 34 drive the side scrapers 35 located on both sides to move. When the side scrapers 35 slide outward from the mounting recesses 330, the overall width of the scraper 3 increases. When the side scrapers 35 slide inward from the mounting recesses 330, the overall width of the scraper 3 decreases. The adjustable width of the scraper 3 allows it to flexibly meet the special needs of sewage treatment tanks 1 of different sizes, better adapt to changes in the internal structure of the sewage treatment tank 1, and improve the versatility of the equipment. The second hydraulic cylinder 34 is the same as the first hydraulic cylinder 22, both of which adopt existing technology, such as a hydraulic cylinder of model K20-50-25.

[0026] Scraper strips 36 are provided at the bottom of the side scraper 35 and on the side wall near the sewage treatment tank 1. The sludge in the sewage treatment tank 1 can be scraped and cleaned more thoroughly by scraping the scraper strips 36, thereby improving the sludge cleaning effect.

[0027] The scraper 36 is a detachable structure, which facilitates timely replacement or cleaning, ensures the scraping effect of the scraper 36, and improves the overall sludge cleaning effect of the equipment.

[0028] like Figure 1 , 2As shown, the sludge cleaning assembly 4 includes a sludge collection box 40 located on the upper end of the support mounting frame 2, a sludge suction box 41 connected to the bottom end of the support mounting frame 2 via a connecting column 410, a linkage vertical plate 42 slidably connected to the front and rear sides of the scraper 3, six folded sludge suction pipes 43 located on the side wall of the sludge suction box 41, and a sludge suction head 44 located at the bottom end of each folded sludge suction pipe 43. The upper end of the scraper 3 is provided with a connecting horizontal plate 32 connected to each linkage vertical plate 42 via an electric telescopic rod 31. The side wall of the linkage vertical plate 42 is provided with six fixing rings 420 for fixing and connecting the bottom ends of each folded sludge suction pipe 43. The sludge collection box 40 and the sludge suction box 41 are connected by a connecting pipe and a sludge pump 45 is provided at the connection point. The sludge suction head 44 and the electric telescopic rod 31 both adopt existing technologies. For example, the sludge suction head 44 can be a single-pipe scraper sludge suction machine of model DXGN, and the electric telescopic rod 31 can be an electric telescopic rod of model YNT-03.

[0029] This embodiment describes a method for using equipment for cleaning sludge from wastewater treatment ponds, including the following steps:

[0030] S1. When it is necessary to clean the sludge on the inner wall of the sewage treatment tank 1, the first hydraulic cylinder 22 drives the support vertical rod 21 to move forward in the corresponding sliding adjustment groove 10, while the mounting horizontal plate 20 and the scraper 3 move synchronously. During the movement of the scraper 3, the sludge on the inner wall of the sewage treatment tank 1 is scraped off and collected together.

[0031] S2. The electric telescopic rod 31 drives the corresponding linkage vertical plate 42 to move downward along the side wall of the scraper 3 until the suction head 44 comes into contact with the accumulated sludge. At this time, the sludge is drawn into the suction box 41 through the corresponding folded suction pipe 43 by the suction head 44. Then, the sludge temporarily stored in the suction box 41 is extracted by the sludge pump 45 and cleaned.

[0032] S3. When in use, the width of the scraper 3 can be adjusted according to the size of the sewage treatment tank 1. Specifically, the two second hydraulic cylinders 34 drive the side scrapers 35 located on both sides to move. When the side scrapers 35 slide outward from the mounting recess 330, the overall width of the scraper 3 increases. When the side scrapers 35 slide inward from the mounting recess 330, the overall width of the scraper 3 decreases.
