Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater and sludge treatment device. Background Technology

[0002] Wastewater treatment plants generate sludge during the wastewater treatment process. Sludge is an aggregate formed by suspended solids, microorganisms, organic matter adsorbed by microorganisms, and metabolic products of microorganisms in wastewater. It may also contain a large amount of heavy metals, pathogens, and viruses. Therefore, sludge should be separated from wastewater during wastewater treatment. A common separation method is drying treatment, which removes water from the sludge, allowing it to dry and solidify before transporting it for further processing, thereby reducing the environmental impact of sludge.

[0003] Existing wastewater and sludge treatment methods involve settling wastewater in a wastewater tank, with the sediment above the sludge layer being discharged to the next process. The sludge, however, needs to be scraped from the bottom of the wastewater tank into a sludge discharge trough for discharge. Typically, machines use scrapers to directly scrape the sludge in the settling tank. During the scraping process, the agitation caused by the scrapers makes the wastewater in the settling tank turbid again, greatly reducing the wastewater settling effect and affecting the efficiency of subsequent wastewater treatment. Therefore, a wastewater and sludge treatment device is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This embodiment of a sewage sludge treatment device includes a sedimentation tank 1. The four inner walls of the sedimentation tank 1 are each provided with annular movable grooves 2. A first motor 3 is fixedly installed on the rear side of the sedimentation tank 1, with its output end extending into the movable grooves 2 and located on its inner right side. A roller 4, rotatably mounted to the output end of the first motor 3 and rotatably mounted to the inner front wall of the sedimentation tank 1, is fixedly installed between the front and rear inner walls of the sedimentation tank 1. A traction rod 5, located within the movable grooves 2, is slidably installed between the outer side of the roller 4 and the outer side of the traction rod 5. A steel coil, located within the movable grooves 2, is fixedly installed between the outer side of the roller 4 and the outer side of the traction rod 5. A second motor 7, with its output end extending into the movable trough 2 and located on the left side, is fixedly installed on the rear side of the sedimentation tank 1. A rotating shaft 8, which is rotatably mounted on the inner front wall of the sedimentation tank 1, is fixedly installed on the output end of the second motor 7. Two winding wheels 9, symmetrically distributed front and back, are fixedly installed on the outer side of the rotating shaft 8. The winding roller 4, the traction rod 5, and the rotating shaft 8 are arranged parallel to each other. A traction rope 10, which is fixedly installed on the outer side of both winding wheels 9 and is parallel to the outer side of the traction rod 5, is fixedly installed on the outer side of both winding wheels 9. Both winding wheels 9 are H-shaped to facilitate the winding of the traction rope 10.

[0022] In this embodiment, a sludge scraping mechanism 11 and a sludge discharge mechanism 12 are provided on the inner bottom of the sedimentation tank 1, both located below the movable trough 2. The sludge scraping mechanism 11 includes an electric telescopic rod 111 fixedly installed on the left side of the sedimentation tank 1 with its output end extending into the interior. A sludge scraper 112 is fixedly installed on the right side of the output end of the electric telescopic rod 111. The sludge scraper 112 is L-shaped. The sludge discharge mechanism 12 includes a sludge storage trough 121 opened on the inner bottom wall of the sedimentation tank 1. The inner left wall of the sludge storage trough 121 is inclined. A third motor 122 with its output end extending into the sludge storage trough 121 is fixedly installed on the rear side of the sedimentation tank 1. A spiral shaft 123 rotatably installed on the output end of the third motor 122 is fixedly installed on the front inner wall of the sedimentation tank 1. A sludge discharge port 13 communicating with the sludge storage trough 121 is opened on the front side of the sedimentation tank 1.

[0023] It should be noted that the width of the steel coil 6 is compatible with the inner width of the sedimentation tank 1, and the length of the steel coil 6 is not less than the inner length of the sedimentation tank 1. A steel coil 6 of sufficient size can completely isolate the sewage inside when it moves to the left side of the inner left wall of the sedimentation tank 1, thereby achieving a stratification effect. The lengths of the two traction ropes 10 are not less than the inner length of the sedimentation tank 1. Sufficiently long traction ropes 10 are necessary to pull the steel coil 6 to the required displacement distance. Both traction ropes 10 are made of steel, which has high strength, wear resistance, corrosion resistance, and long service life.

[0024] The working principle of the above embodiments is as follows:

[0025] After the sewage and sludge settle in the sedimentation tank 1, when sludge needs to be discharged, the second motor 7 is started. The output end of the second motor 7 drives the rotating shaft 8 to rotate. The two winding wheels 9 on the rotating shaft 8 rotate and wind up the traction rope 10. The traction rope 10 pulls the traction rod 5 to move to the left in the movable groove 2. The traction rod 5 pulls the steel coil plate 6 to move to the left. The winding roller 4 releases the steel coil plate 6 until the steel coil plate 6 is completely moved to the left side of the inner side of the sedimentation tank 1, thereby achieving the separation of the sludge at the bottom of the upper sedimentation tank 1. Then, the electric telescopic rod 111 is started. The output end of the electric telescopic rod 111 pushes the scraper 112 to move to the right, pushing the sludge at the bottom of the sedimentation tank 1 into the sludge storage tank 121. Due to the isolation of the steel coil plate 6, the bottom sludge push greatly reduces the sedimentation effect on the upper sedimentation tank 1, improving the sewage treatment efficiency. The third motor 122 is started to drive the spiral shaft 123 to rotate and discharge the sludge from the sludge discharge port 13.
