Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a waterway dredging silt solidification treatment device based on water conservancy engineering. Background Technology

[0002] In the fields of water conservancy construction and inland waterway maintenance, waterway dredging is an important engineering measure to ensure navigation safety and improve navigation capacity. With the growth of shipping demand and the aggravation of river siltation, the large amount of silt generated by dredging each year, if not properly handled, will not only occupy a large amount of land resources, but may also cause secondary pollution to the soil, water bodies and atmospheric environment due to the leakage and diffusion of pollutants rich in the silt.

[0003] The prior art discloses a device for solidifying dredged sludge in water conservancy projects, with publication number CN115231788B. This device addresses the problems of inconvenient material feeding and difficulty in discharging residual solidified sludge in existing sludge solidification equipment. The device has a sludge feed pipe installed above its main body and a solidified sludge discharge pipe installed below it. Fixed sleeves are installed on both sides of the upper part of the main body, with a sealing piston head installed inside each sleeve. A threaded sleeve is installed at the upper end of the sealing piston head, and a threaded screw is installed inside the threaded sleeve. Two movable baffles are installed at the lower end of the solidified sludge discharge pipe, each with an electric cylinder installed below it. A lifting platform is installed at the upper end of the main body, with hydraulic lifting cylinders installed on both sides of the lower surface of the lifting platform.

[0004] The aforementioned waterway dredging sludge solidification treatment equipment based on water conservancy engineering uses a retractable electric cylinder to drive a movable baffle. After the movable baffle is opened, the solidified sludge can be easily discharged. However, the aforementioned waterway dredging sludge solidification treatment equipment does not have a quantitative component, which makes it impossible to premix the solidifying agent with the sludge in a certain proportion when adding it. It cannot be determined according to the properties of the sludge and the treatment requirements, and the treatment accuracy cannot be guaranteed. The effect during use is not good, and this needs to be improved. Utility Model Content

The end of the guide tube 305 away from the hollow connecting block 304 is fixedly connected to the side of the feed box 306. A through groove is opened on the top of the hollow connecting block 304. The diameter of the through groove is adapted to the diameter of the guide tube 305. The through groove allows the guide tube 305 to extend into and connect to the conveying pump, enabling the conveying of sludge. The sludge is conveyed to the top for convenient subsequent processing. The guide tube 305 extends through the top of the hollow connecting block 304 and connects to the top of the conveying pump.

[0021] The mixing and pressing assembly 4 includes a processing box 401, a motor 402, a discharge drawer 403, a rotating rod 404, mixing blades 405, a connecting frame 406, a hydraulic telescopic rod 407, and a pressing plate 408. The processing box 401 is fixedly connected to the center of the surface of the processing box 2 and to the top of the placement rack 1. The motor 402 is fixedly connected to the inside left side of the processing box 401. The rotating rod 404 is fixedly connected to the output shaft of the motor 402. The mixing blades 405 are fixedly connected to the surface of the rotating rod 404. The inside top of the connecting frame 406 is... A hydraulic telescopic rod 407 is fixedly connected to the end of the device. A pressing plate 408 is fixedly connected to the bottom of the hydraulic telescopic rod 407. A discharge drawer 403 is inserted into the front of the processing box 401. A hollowed-out rectangular groove is provided on the back of the discharge drawer 403. The length of the hollowed-out rectangular groove is adapted to the length of the pressing plate 408.

[0022] In use, the placement rack 1 is placed on both sides of the waterway, and the collection rack 301 is positioned in the area to be dredged. The sludge suction pump 303 can be activated to generate suction, which can adsorb the sludge in the waterway. The sludge then enters the hollow connecting block 304 through the collection rack 301. A conveying pump is installed inside the hollow connecting block 304, which, together with the guide pipe 305, conveys the sludge to the inside of the feed box 306. During use, a hardening agent (such as cement, lime, etc.) can be added through the connecting frame 307, and added in a certain proportion. Premixing with sludge requires precise metering. A metering mechanism is installed inside the connecting frame 307. During use, the curing agent is added and falls onto the top of the guide plate 308, specifically onto the top right side of the guide plate 308. A spring 314 is located at the bottom of the guide plate 308. Continuous addition of curing agent compresses the spring 314, causing the guide plate 308 to rotate clockwise around the connecting shaft 309. The weight increases until it is pressed together at approximately a 45-degree angle to the lower right. At this point, the right side of the elastic pad 311 is aligned with the connecting frame. There is a gap on the right side of the interior of 307, which allows the curing agent to be continuously added. As the weight decreases, the spring 314 returns to its original position until no more can be added. The amount added at one time is controlled by controlling the elastic force of the spring 314. When adding, it is premixed with sludge in a certain proportion, and the ratio is determined according to the properties of the sludge and the treatment requirements to ensure the accuracy of the treatment. After adding the set sludge and curing agent, it can enter the interior of the treatment box 401. Inside the treatment box 401, the motor 402 can be activated to drive the rotating rod 404 and the mixing blade 405 to rotate, which fully stirs the sludge and makes the curing agent and sludge evenly mixed. After mixing, it falls into the position below the partition plate through the connecting groove. Then, the hydraulic telescopic rod 407 is activated to move the pressing plate 408 upward for pressing, draining excess water and promoting the tight bonding between sludge particles to form a relatively solid solid body. Then, by pulling the discharge drawer 403, the pressed sludge can be easily removed and placed on the discharge drawer 403 for removal, completing the sludge curing treatment.
