Description

Technical Field

[0001] This utility model relates to the field of sludge collection technology, specifically to a negative pressure suction sludge collection device. Background Technology

[0002] Toxic sludge refers to solid waste generated during industrial production, municipal sewage treatment, or wastewater treatment in special industries. It contains toxic and hazardous substances that exceed the environmental risk threshold for general sludge. Due to its high concentration of pollutants, improper disposal can pose a serious threat to the ecological environment and human health, and it is usually classified as hazardous waste. The collection process for toxic sludge treatment faces numerous challenges.

[0003] Traditional manual excavation and loading methods are inefficient and labor-intensive. Workers also face the risk of exposure to harmful substances in the sludge. While mechanical shoveling and other methods have improved efficiency to some extent, they can easily cause oil sludge to scatter, leading to secondary pollution. Furthermore, they are difficult to effectively collect oil sludge in complex terrain and confined spaces. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a negative pressure suction sludge collection device.

[0005] The technical solution of this utility model is: a negative pressure suction sludge collection device, including a collection cylinder, a sludge gathering component that is rotatably clamped to the outside of the collection cylinder, and a suction component set inside the collection cylinder; the top of the collection cylinder is closed and the bottom is open, a traction rope is connected to the top of the collection cylinder, a partition is set at the upper position inside the collection cylinder, and several suction holes are provided through the lower end of the outer wall of the collection cylinder. The sludge collection assembly includes a rotating sleeve that is rotatably engaged on the outer wall of the collection cylinder, several uprights equidistantly distributed on the bottom surface of the rotating sleeve, and arc-shaped collection plates respectively set at the bottom end of each upright; an internal gear ring located above the partition is sleeved inside the rotating sleeve, and several small gears that mesh with the internal gear ring are rotatably engaged inside the collection cylinder; a drive motor is set at the top of the collection cylinder, and the output end of the drive motor is connected to a drive gear that meshes with each of the small gears simultaneously; The suction assembly includes a piston plate that is slidably engaged inside the collection cylinder and an electric telescopic rod disposed on the bottom surface of the partition and connected to the piston plate. The electric telescopic rod is covered with a telescopic sleeve.

[0006] Furthermore, an anti-slip support plate is provided on the side of the arc-shaped collecting plate near the collecting cylinder; Explanation: By setting anti-slip support plates, sludge slides off the arc-shaped collection plate during rotation, which helps improve the sludge collection efficiency of the arc-shaped collection plate.

[0007] Furthermore, the outside of the collection cylinder is fitted with a reinforcing sleeve that is simultaneously fixedly connected to each of the uprights; Note: By installing a reinforcing sleeve, the structural stability of the upright can be improved, and deformation of the upright due to the resistance of the sludge can be prevented when the upright rotates with the rotating sleeve.

[0008] Furthermore, a first mounting seat connected to the output end of the drive motor is provided on the bottom surface of the partition plate; a second mounting seat is rotatably engaged on the upper surface of the piston plate; the two ends of the telescopic sleeve and the electric telescopic rod are respectively fixedly connected to the first mounting seat and the second mounting seat; several mixing plates are equidistantly distributed along the circumference of the outer side of the second mounting seat. Explanation: During the rotation of the drive motor, the first and second mounting bases can rotate synchronously. The mixing plate can stir and mix the sludge collected inside the collection cylinder, improving the uniformity and fluidity of the sludge and preventing it from sticking to the inner wall of the collection cylinder.

[0009] Furthermore, a sealing sleeve for blocking the suction hole is slidably connected inside the collection cylinder, a return spring that abuts against the upper end face of the sealing sleeve is provided inside the collection cylinder, a trigger rod that penetrates the collection cylinder is provided at the bottom end of the sealing sleeve, and a docking ring connected to the trigger rod is provided below the collection cylinder. Instructions: When the collection cylinder contacts a hard surface, the docking ring pushes the trigger rod and sealing sleeve to move upward along the inner wall of the collection cylinder. At this time, all suction holes open, and sludge enters the collection cylinder through the suction holes.

[0010] Furthermore, a limiting ring is fitted inside the collection cylinder and above the suction hole; Note: Using a limit ring to limit the movement of the piston plate helps improve the reliability of the equipment.

[0011] The working principle of this utility model is as follows: In use, connect the traction rope to the external traction device, and use the external traction device to lower the collection cylinder to the sludge collection area. Under the action of gravity, the collection cylinder sinks to the bottom of the sludge. Then, the drive motor drives the drive gear to rotate. The connection between the drive gear, pinion, and internal gear ring drives the rotating sleeve to rotate outside the collection cylinder. During the rotation of the rotating sleeve, the arc-shaped collecting plate pushes the sludge through the suction hole into the collection cylinder. Then, the electric telescopic rod drives the piston plate to move upward along the inner wall of the collection cylinder to above the suction hole. At this time, the pressure in the sealed space formed by the collection cylinder and the piston plate is less than the pressure outside the collection cylinder, so that the sealed space formed by the collection cylinder and the piston plate creates a negative pressure environment. Finally, the external traction device is used to transfer the collection cylinder and discharge the sludge collected inside the collection cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects: First, the structure of this utility model is reasonably designed. It uses a piston plate to press the sludge into the collection cylinder in a negative pressure environment, which effectively avoids the harm caused by toxic substances in the sludge to workers and the external environment, and improves the safety and efficiency of sludge collection and treatment. Secondly, the rotating sludge collecting component of this utility model can not only move the sludge into the inside of the collecting cylinder, but also stir and disperse the sludge, ensuring the uniformity and fluidity of the sludge texture, and preventing the sludge from sticking to the inner wall of the collecting cylinder and affecting the operating energy consumption of the collecting cylinder. Third, during use, this utility model guides the sludge into the sealed space formed by the collection cylinder and the piston plate, and then transfers the collection cylinder, effectively avoiding the secondary pollution problem caused by the sludge scattering during collection.
