Description

Technical Field

[0001] This utility model relates to the field of scraper and suction sludge machines, specifically to a full-bridge scraper and suction sludge machine bridge frame device. Background Technology

[0002] The sludge scraper is a type of wastewater treatment equipment. Its main working principle is that the drive device drives the sludge scraper to rotate around the center of the sedimentation tank. After the raw water settles in the sedimentation tank, the supernatant is discharged from the overflow weir plate. The sludge settled at the bottom of the tank is slowly pushed along the bottom of the tank to the central sludge collection trough by the logarithmic spiral curved scraper. Then, the sludge is discharged through the sludge discharge pipe by the spiral conveyor.

[0003] Chinese patent discloses a protective structure for storage batteries (authorization announcement number CN 216773407 U). This patented technology can solve the problems of existing sludge scraper devices, such as inconvenient cleaning of the sludge discharge pipe, easy blockage of the sludge discharge pipe, affecting sludge discharge efficiency and resulting in high limitations in use.

[0004] In this patent, sewage still exists in the sludge. Due to the lack of a separation device, the sludge becomes highly adhesive after the solid and liquid are mixed, making it difficult to clean it later. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a full-bridge type scraper and suction sludge machine bridge frame device, including a sedimentation tank and a sludge suction pump. The sedimentation tank is symmetrically arranged with a base frame on the left and right sides. A bottom beam is installed on the upper end face of the base frame.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-5 This embodiment provides a full-bridge sludge scraper bridge device, including a sedimentation tank 1 and a sludge pump 2. The sedimentation tank 1 has a base frame arranged symmetrically on the left and right sides. A bottom beam 11 is installed on the upper end face of the base frame. A placement cavity 12 is installed on the upper end face of the bottom beam 11. A separation box 13 is installed on the outer wall of the placement cavity 12. A limit spring 14 is installed at the top of the placement cavity 12. A pressure plate 15 is installed at the bottom of the limit spring 14. The sludge pump 2 is installed at the bottom of the placement cavity 12. A sludge suction pipe 25 is installed at the bottom of the sludge pump 2. Multiple through holes 16 are opened on the outer wall of the placement cavity 12 along its circumferential direction. When working, the sludge pump 2 starts and pumps the sludge in the sedimentation tank 1 into the placement cavity 12 through the sludge suction pipe 25. The sludge drives the pressure plate 15 to rise. At the same time, the limit spring 14 presses the pressure plate 15, thereby causing the sewage in the sludge to seep out. The sewage enters the separation box 13 through the through holes 16, thereby enabling solid-liquid separation of sludge and sewage, which is convenient for subsequent post-processing.

[0021] An outer pipe 17 is installed on the outer wall of the sludge suction pipe 25 by a rotating fit. Multiple base plates 18 are installed on the outer wall of the outer pipe 17 along its circumferential direction. A side scraper 19 is installed on the outer end of the base plate 18, and a lower scraper 21 is installed at the bottom of the base plate 18. Multiple driven bevel gears 22 are installed on the outer end of the outer pipe 17, and multiple driving bevel gears 23 are installed on the outer wall of the driven bevel gears 22. A first motor 24 is installed on the right end face of the driving bevel gear 23. When working, the first motor 24 starts and drives the driving bevel gear 23 to rotate. The driving gear drives the driven bevel gear 22 to rotate, causing the outer pipe 17 to rotate, thereby driving the base plate 18 to rotate. The side scraper 19 can scrape the sludge on the inner wall of the sedimentation tank 1, and the lower scraper 21 can scrape the sludge at the bottom of the sedimentation tank 1, thereby ensuring the sludge scraping effect inside the sedimentation tank 1.

[0022] An air inlet pipe is installed on the outer wall of the mud suction pipe 25, and a control valve is installed on the outer wall of the air inlet pipe. An air pump 26 is installed on the left end face of the air inlet pipe. When the mud suction pipe 25 is blocked during operation, the control valve is opened, the air pump 26 is turned on, and gas enters the mud suction pipe 25 through the air inlet pipe, thereby clearing the blockage of the mud suction pipe 25.

[0023] An adjusting cylinder 27 is installed on the upper surface of the placement cavity 12. A top plate is installed on the output end of the adjusting cylinder 27. Push rods are symmetrically installed on the bottom of the top plate. The push rods pass through the upper surface of the placement cavity 12 and are connected to it by a sliding fit. A fixing groove is opened at the bottom of the push rod. A spring pressure rod 28 is installed at the top of the fixing groove. When working, the adjusting cylinder 27 is activated, which drives the push rod to move up and down, thereby patting the pressure plate 15, which further improves the pressing and dewatering effect of the sludge. When the push rod moves, the spring pressure rod 28 vibrates up and down, which further improves the patting effect of the pressure plate 15.

[0024] The placement cavity 12 consists of a chassis and a cavity 29. The cavity 29 is installed on the upper end face of the chassis by a threaded connection. During operation, the cavity 29 is disassembled by a screw connection to facilitate the cleaning of the sludge inside.

[0025] In operation, the sludge pump 2 is started, and the sludge in the sedimentation tank 1 is pumped into the placement chamber 12 through the sludge suction pipe 25. The sludge drives the pressure plate 15 to rise, and at the same time, the limit spring 14 presses the pressure plate 15, thereby causing the sewage in the sludge to seep out. The sewage enters the separation box 13 through the through hole 16, thereby enabling solid-liquid separation of sludge and sewage, which is convenient for subsequent post-processing.

[0026] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
