Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage sedimentation treatment device. Background Technique

[0002] The horizontal flow sedimentation tank is an important water treatment structure, mainly used to remove suspended particles in water. The water flow moves horizontally in the tank, and the particles settle to the bottom of the tank under the action of gravity. The sludge scraper scrapes the accumulated sludge at the bottom into the sludge discharge hopper to achieve solid-liquid separation. It has a simple structure, convenient management, and strong adaptability. It is widely used in large and medium-sized water supply plants and areas with high groundwater level and poor geology.

[0003] In the prior art during use, the existing sludge scraping mechanism is usually a chain belt structure, which installs a plurality of sludge scraping plates on the chain, and uses a motor to drive the chain to rotate, and then drives the sludge scraping plates to longitudinally translate at the bottom of the horizontal flow sedimentation tank. However, during this cleaning operation, a large amount of agitation will be caused to the sludge at the bottom of the tank, and the turned sludge will cause the water quality in the sedimentation tank to become turbid, causing secondary pollution to the clarified water that has been precipitated in the upper part of the sedimentation tank. If the cleaning method of lowering the water level or draining the water is adopted, the cleaning time will be greatly extended and the cleaning efficiency will be reduced.

[0039] During use, the wastewater flows into the pool from one end, flows horizontally through the pool, and the suspended solids gradually settle to the bottom of the pool during the flow. After a period of sedimentation, the sludge scraper is started to scrape the sludge into the sludge tank at the bottom of the sedimentation tank, and then the clarified liquid flows out from the other end of the pool.

[0040] In the related art, the sludge scraping mechanism is usually a chain belt structure, in which multiple sludge scraping plates are generally installed on the chain. The motor drives the chain to rotate, and then drives the sludge scraping plate to longitudinally translate at the bottom of the horizontal flow sedimentation tank. Although it can scrape the sludge at the bottom into the sludge discharge port to ensure the normal operation of sewage treatment, during this cleaning operation, a large amount of agitation will be caused to the sludge at the bottom of the tank, and the agitated sludge will cause the water quality in the sedimentation tank to become turbid, resulting in secondary pollution to the clarified water that has been sedimented in the upper part of the sedimentation tank. If the cleaning method of lowering the water level or draining the water is adopted, the cleaning time will be greatly prolonged and the cleaning efficiency will be reduced, which has certain limitations.

[0041] To solve the problems in the related art to a certain extent, the embodiment of the present application provides a sewage sedimentation treatment device. When in use, the driving device three 24 is started, and the waterproof cloth 23 is pulled out. When the scraper 14 scrapes the sludge into the sludge tank 12, the waterproof cloth 23 plays a separating role to prevent the sludge and water from mixing again, which is more convenient and fast and convenient for the operator to use.

[0042] Combined with Figures 1 - 6 , the embodiment of the present application provides a sewage sedimentation treatment device, including: a sewage sedimentation treatment device, including a main body assembly main body assembly 1; the main body assembly main body assembly 1 includes: a sedimentation tank 11, which is fixedly connected to a sludge tank 12 below; a transmission device 13, arranged at the inner bottom of the sedimentation tank 11; a scraper 14, fixedly connected to the transmission device 13; a driving device one 15, fixedly connected to one side of the sedimentation tank 11; a sludge discharge pipe 16, fixedly connected to the bottom of the sludge tank 12; a sewage discharge tank 17, fixedly connected to one side of the sedimentation tank 11; a separating component 2 is arranged inside the sedimentation tank 11; the separating component 2 includes: a driving device two 21, arranged below the sewage discharge tank 17; a transmission shaft one 22, rotatably connected to the inside of the sedimentation tank 11; a waterproof cloth 23, fixedly connected to the transmission shaft one 22; a driving device three 24, arranged on the sedimentation tank 11; a transmission shaft two 25, rotatably connected to the driving device three 24; one end of a rope 26 is fixedly connected to the waterproof cloth 23; the other end is fixedly connected to the transmission shaft two 25.

[0049] In some embodiments, the auxiliary component 8 provided on the tops of the first cover plate 72 and the second cover plate 722 facilitates grasping and makes it easier to open and close.

[0050] In some embodiments, the sliding component 9 provided outside the sedimentation tank 11 and the sewage discharge tank 17 enables the first protective shell 61 to be slidably disassembled and assembled, facilitating maintenance.

[0051] In some embodiments, the second driving device 21 includes: a motor 211 fixedly connected to the sewage discharge tank 17; a driving wheel 212 rotatably connected to the motor 211; a driven wheel 213 fixedly connected to one side of the first transmission shaft 22; and a chain 214 disposed on the driving wheel 212, and the driving wheel 212 is drivingly connected to the driven wheel 213 through the chain 214.

[0052] When current is applied to the motor 211, this switch has six interfaces: two input terminals, two output terminals, and two intermediate contacts. The motor 211 has three pins: U, V, and W, where U and V are the main phases and W is the neutral line. Connect the U and V pins of the motor 211 to input 1 and input 2 of the DPDT switch, and connect the W pin to the ground wire. Then, connect output 1 and output 2 of the switch to the power supply respectively.

By switching the direction of the DPDT switch, the forward and reverse rotations of the motor 211 can be controlled. When the motor 211 rotates forward, it drives the driving wheel 212 to rotate, and drives the driven wheel 213 to rotate forward through the chain 214, and the first transmission shaft 22 fixed thereto can rotate to wind up the waterproof cloth 23 fixed thereon onto the first transmission shaft 22.
