Description

Technical Field

[0001] This utility model relates to the field of wheel-type sand washing machines, specifically a dredging structure for a wheel-type sand washing machine. Background Technology

[0002] A wheel-type sand washing machine is a type of bucket wheel washing and screening equipment that can clean and separate stone powder and mud from sand and gravel. The wheel-type sand washing machine mainly consists of a washing wheel, a washing tank, and a drive system. The drive system drives the washing wheel to rotate, and during the rotation of the washing wheel, it scoops up the material in the washing tank, thereby achieving separation of material and water. In traditional sand washing machines, when separating material and water, the wastewater that has been washed flows back into the washing tank. As more and more stone powder and mud are added to the wastewater, the cleaning effect on the sand and gravel becomes less and less. Moreover, the stone powder and mud will gradually form silt in the wastewater, which will gradually increase the rotational resistance of the washing wheel, thereby increasing the load on the drive system. Utility Model Content

[0003] The purpose of this utility model is to provide a dredging structure for a wheel-type sand washing machine to overcome the above-mentioned defects in the prior art.

[0004] According to the present invention, a dredging structure for a wheel-type sand washing machine includes a rotating shaft, the rotating shaft being aligned with the axis of the sand washing wheel of the wheel-type sand washing machine, the sand washing wheel being fixed on the rotating shaft, a cylindrical body being provided outside the rotating shaft, a sleeve being rotatably connected to the rotating shaft, several connecting rods being fixed between the outer periphery of the sleeve and the cylindrical body, a through groove being provided on the upper side of the cylindrical body, a filter cloth being fixed inside the through groove, a surrounding plate being fixed on the upper side of the rotating shaft surrounding the filter cloth, and the center of gravity of the dredging structure being located below the rotating shaft.

[0005] With the above technical solution, during the rotation of the sand washing wheel, the material rotates with the sand washing wheel to the sand washing tank for separation. The material is then separated from the water, and most of the wastewater is poured onto the filter cloth. Through the filtration effect of the filter cloth, the sludge in the wastewater is filtered and collected on the filter cloth, thereby reducing the accumulation of sludge in the sand washing tank, improving the cleaning effect of the material, and reducing the resistance of sludge to the sand washing wheel.

[0006] Preferably, the lower half of the cylinder is arc-shaped, the center of the cylinder coincides with the axis of the rotating shaft, the upper half of the cylinder is concave in an arc shape towards the rotating shaft, and the filter cloth is a downward concave arc shape.

[0007] Through the above technical solution, the downward-concave arc-shaped filter cloth can not only increase the filtration area of ​​the filter cloth, but also increase the amount of sludge collected.

[0008] Preferably, the enclosure and the filter cloth together form a sludge removal chamber for filtering sludge from sewage, and the sludge collects in the sludge removal chamber.

[0009] The above-mentioned technical solution allows the sludge to accumulate in the dredging chamber, which is beneficial for the centralized treatment of the sludge.

[0010] Preferably, the sleeve and the rotating shaft are rotatably connected by a bearing.

[0011] The above technical solution connects the sleeve and the rotating shaft via a bearing, reducing the rotational friction between the sleeve and the rotating shaft and thus preventing the sleeve from flipping when the rotating shaft rotates.

[0012] Preferably, a counterweight is fixed at the lowest point of the inner wall of the cylinder.

[0013] Through the above technical solution, the setting of the counterweight further lowers the center of gravity of the dredging structure, thereby increasing the stability of the dredging structure.

[0014] The beneficial effects of this utility model are as follows: During the rotation of the sand washing wheel, the material rotates with the sand washing wheel to the top of the sand washing tank, where the material is separated from the water. Most of the wastewater is poured onto the filter cloth, and through the filtration effect of the filter cloth, the sludge in the wastewater is filtered and collected on the filter cloth, thereby reducing the accumulation of sludge in the sand washing tank and improving the cleaning effect of the material. At the same time, it reduces the resistance of sludge to the sand washing wheel. The setting of the counterweight further lowers the center of gravity of the sludge removal structure, thereby increasing the stability of the sludge removal structure during the rotation of the rotating shaft.

[0022] One embodiment of this utility model:

[0023] Reference Figures 1-3 This utility model provides a dredging structure for a wheel-type sand washing machine, including a rotating shaft 10, which coincides with the axis of the sand washing wheel of the wheel-type sand washing machine. The sand washing wheel is fixed on the rotating shaft 10. A cylinder 11 is provided outside the rotating shaft 10. A sleeve 14 is rotatably connected to the rotating shaft 10. Several connecting rods 12 are fixed between the outer periphery of the sleeve 14 and the cylinder 11. A through groove 13 is opened on the upper side of the cylinder 11, and a filter cloth 30 is fixed in the through groove 13. A ring of material surrounding the filter cloth 30 is fixed on the upper side of the rotating shaft 10. The center of gravity of the sludge removal structure is located below the rotating shaft 10. The lower half of the cylinder 11 is arc-shaped, and the center of the cylinder 11 coincides with the axis of the rotating shaft 10. The upper half of the cylinder 11 is concave and arc-shaped towards the rotating shaft 10. The filter cloth 30 is concave and arc-shaped. The enclosure 15 and the filter cloth 30 together form a sludge removal chamber for filtering sludge in sewage. The sludge collects in the sludge removal chamber. The sleeve 14 is rotatably connected to the rotating shaft 10 through a bearing. A counterweight 20 is fixed at the lowest point of the inner wall of the cylinder 11.

[0024] In use, the drive system rotates the sand washing wheel, and the bucket-shaped cavity in the sand washing wheel scoops up the sand and gravel material in the sand washing tank, causing it to gradually rotate to the upper side of the sand washing tank. The sand and gravel material gradually separates from the water. Most of the wastewater after washing the sand and gravel material is poured onto the filter cloth 30. Through the filtration effect of the filter cloth 30, the stone powder and mud in the wastewater are filtered onto the filter cloth 30, and the wastewater flows back into the sand washing tank, thereby reducing the stone powder and mud content in the wastewater of the sand washing tank, reducing the formation of silt, thereby increasing the cleaning effect of the wheel sand washing machine on the sand and gravel material, while reducing the resistance of silt to the sand washing wheel.
