It adopts a double-suction hood design, increasing the coverage width of a single operation. The sludge inlet and guide plate on the front of the suction hood help to smoothly guide the sludge, reducing the probability of clogging. Support rollers allow the device to move smoothly, easily covering a larger area and reducing dead corners. The flushing nozzle and suction device are integrated into one unit. The high-pressure nozzle is connected to the support column through a ball-head-ball-head seat structure, allowing for flexible adjustment of the flushing angle and achieving "instant flushing and suction" of the sludge. Flushing and suction are performed simultaneously, greatly improving cleaning efficiency and effectiveness.

Description

Technical Field

[0001] This utility model belongs to the technical field of dredging equipment, specifically relating to a sludge cleaning device for a sedimentation tank of dyeing and printing wastewater. Background Technology

[0002] In the treatment of dyeing and printing wastewater, a large amount of viscous sludge accumulates at the bottom of the sedimentation tank, requiring regular cleaning. Before the advent of this device, traditional sludge cleaning methods may have one or more of the following technical challenges:

[0003] Traditional methods using a single sludge pump or manual scraping are ill-suited to the complex contours of the sedimentation tank bottom. Areas such as the corners and slopes at the bottom of the tank are prone to becoming cleaning dead zones, leading to long-term sludge accumulation. This affects the effective volume and treatment efficiency of the sedimentation tank, and can even cause blockages and secondary pollution. Dyeing and printing sludge is typically highly viscous and may contain fibrous debris. A single sludge suction port is easily clogged by clumps of sludge or debris when it gets close to the sludge, requiring repeated lifting and cleaning, resulting in low work efficiency and an inconsistent cleaning process.

[0004] In traditional operation mode, high-pressure flushing and sludge suction are often two independent and sequential processes. First, the sludge is manually dispersed by a high-pressure water gun, and then it is extracted by a sludge suction pump. This mode has the disadvantages of poor coordination, high energy consumption, and long time consumption. Moreover, the dispersed sludge cannot be sucked away immediately and may re-sediment or spread. Summary of the Invention

[0005] The present invention mainly addresses the technical problems existing in the prior art by providing a sludge cleaning device for sedimentation tanks in dyeing and printing wastewater.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a sludge cleaning device for a sedimentation tank of dyeing and printing wastewater, including a flushing nozzle and a suction device. The suction device includes a mounting steel frame. A push rod is provided at the middle of the rear end of the mounting steel frame. The mounting steel frame includes two mounting positions. A sludge suction hood is provided in each of the two mounting positions. A connecting plate connected to the mounting steel frame is provided around the sludge suction hood. A sludge inlet is provided on the front side of the sludge suction hood. A support column is provided in the middle of the mounting steel frame. A ball head is provided at the top of the support column.

[0007] Preferably, the flushing nozzle includes a ball head seat, the bottom of which is rotatably connected to the ball head, and a pipe clamp is provided at the top of the support column. A high-pressure nozzle is provided in the pipe clamp, and a water supply pipe is connected to the rear end of the high-pressure nozzle.

[0008] Preferably, the top of the sludge suction hood is connected to a drain pipe.

[0009] Preferably, a guide plate is provided on each of the left and right sides of the mud inlet.

[0010] Preferably, multiple support rollers are flush with each other on the mounting steel frame corresponding to the two mounting positions.

[0011] Preferably, the upper part of the clamp is connected to a swing handle.

[0012] The beneficial effects of this invention are as follows: The double suction hood design increases the coverage width of a single operation; the sludge inlet and guide plate on the front of the suction hood help to smoothly guide the sludge, reducing the probability of clogging. Support rollers allow the device to move smoothly, easily covering a larger area and reducing dead zones.

[0013] The flushing nozzle and suction device are integrated into one unit. The high-pressure nozzle is connected to the support column through a ball head-ball head seat structure, which can flexibly adjust the flushing angle to achieve "instant flushing and suction" of sludge. Flushing and suction are carried out simultaneously, which greatly improves cleaning efficiency and effect. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] Example: A sludge cleaning device for sedimentation tanks in dyeing and printing wastewater, such as Figures 1-2 As shown, the device includes a flushing nozzle and a suction device. The suction device includes a mounting steel frame with a push rod at the middle of the rear end of the mounting steel frame. The mounting steel frame includes two mounting positions, each of which is equipped with a sludge suction hood. The sludge suction hood is surrounded by connecting plates that connect to the mounting steel frame. The front side of the sludge suction hood is equipped with a sludge inlet. A support column is located in the middle of the mounting steel frame, and the top of the support column is equipped with a ball head.

[0019] The flushing nozzle includes a ball head seat, the bottom of which is rotatably connected to the ball head. A pipe clamp is provided at the top of the support column, and a high-pressure nozzle is provided in the pipe clamp. A water supply pipe is connected to the rear end of the high-pressure nozzle.

[0020] The top of the sludge suction hood is connected to a sewage pipe; a guide plate is provided on each of the left and right sides of the sludge inlet; multiple support rollers are flush with the mounting steel frames corresponding to the two mounting positions; and a swing handle is connected to the upper part of the pipe clamp.

[0021] The principle of this invention is as follows: The cleaning device is placed at the beginning of the sedimentation tank via its bottom support rollers. An external high-pressure water source is connected to the water supply pipe, and a sewage discharge pipe is connected to the sludge conveying pump or collection tank. Simultaneously, the high-pressure water source and the suction device (external sludge pump) are turned on. The high-pressure nozzle sprays a strong water flow that directly impacts the sludge that has hardened at the bottom of the tank, causing it to be dispersed and stirred up, forming a turbid mud-water mixture. At the same time, the suction device generates negative pressure. Under the action of negative pressure, the dispersed mud-water mixture is quickly sucked in through the sludge inlet on the front side of the suction hood. The guide plates on both sides of the sludge inlet play a role in gathering and guiding the mud and water, preventing the mud and water from spreading to both sides, ensuring that the cleaning range is concentrated and improving the suction efficiency.

[0022] The operator slowly pushes the entire device forward using a push rod; the support rollers ensure smooth and effortless movement of the device and effectively protect the bottom impermeable layer from scratches. During the advancement process, the operator can adjust the spray angle of the high-pressure nozzle at any time according to the accumulation of sludge in front. The connection between the ball head and the ball head seat provides flexible omnidirectional adjustment capability, enabling precise flushing of key areas. The sludge suction hood at the rear of the device follows closely behind, instantly and thoroughly sucking away the sludge that has just been flushed, ensuring that "wherever it is flushed, it is sucked up."

[0023] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
