Description

Technical Field

[0001] This utility model relates to the field of mineral sludge treatment technology, specifically to a mobile mineral sludge dewatering and thickening device. Background Technology

[0002] Mineral sludge thickening is a crucial step in mining wastewater treatment. It reduces the moisture content of the sludge, increasing its solids concentration to facilitate subsequent dewatering and treatment. Mineral sludge thickening technology typically involves specialized thickening equipment, such as high-efficiency thickeners and belt conveyor sludge thickening and dewatering systems. These devices effectively treat fine tailings, sludge, and wastewater, improving treatment efficiency and reducing environmental pollution.

[0003] However, existing equipment for dewatering and thickening mineral-containing sludge generally suffers from low processing efficiency and incomplete treatment. Moreover, existing equipment for dewatering and thickening mineral-containing sludge is bulky and difficult to move, which affects its practicality. Furthermore, existing equipment can only dewater mineral-containing sludge and cannot separate and recover the minerals in the sludge, which is not conducive to the resource utilization of mineral-containing sludge. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a mobile mineral-containing sludge dewatering and thickening device.

[0005] The technical solution of this utility model is as follows: a mobile mineral sludge dewatering and thickening device, including an equipment box, a dewatering screen cylinder movably installed inside the equipment box, a drive motor installed at the top of the equipment box and providing power to the dewatering screen cylinder, and several excitation motors equidistantly distributed inside the equipment box and respectively abutting against the dewatering screen cylinder; a feed hole is provided at the top of the equipment box, and a drain pipe is provided at the lower end of the side wall;

[0006] The upper and lower ends of the outer wall of the dewatering screen cylinder are respectively rotatably connected to the first turntable and the second turntable. The top of the dewatering screen cylinder is provided with a first connecting frame and the bottom is provided with a sludge discharge pipe that passes through the equipment box. Several guide columns are evenly distributed on the inner wall of the equipment box and are respectively slidably connected to the first turntable.

[0007] The output end of the drive motor is connected to the first connecting frame; the output end of each excitation motor is provided with an excitation rod that is grounded to the bottom surface of the second turntable.

[0008] Furthermore, the bottom surface of the equipment box is equipped with wheels;

[0009] Note: By installing wheels, the equipment can be easily moved, improving its ease of use.

[0010] Furthermore, a connecting plate is rotatably engaged inside the dewatering screen cylinder and below the first connecting frame. Several sludge scrapers are equidistantly distributed around the bottom surface of the connecting plate, which abut against the inner wall of the dewatering screen cylinder. A second connecting frame is provided on the connecting plate, and a second locking hole is provided on the second connecting frame.

[0011] The first connecting frame is provided with a first locking hole corresponding to the upper and lower positions of the second locking hole; the output end of the drive motor is provided with a chuck that can engage with the first locking hole and the second locking hole respectively via a telescopic shaft; the upper end face of the chuck is provided with an annular groove, and an arc-shaped slider is slidably engaged inside the annular groove, and a push seat is provided on the arc-shaped slider; an adjusting screw is threadedly connected to the equipment box and is engaged with the push seat for rotation.

[0012] Explanation: By adjusting the screw to adjust the push seat, the chuck can be movably engaged with the first and second locking holes respectively. Thus, the drive motor can not only drive the dewatering screen cylinder to rotate and centrifugally dewater the mineral-containing sludge, but also drive the connecting disc to rotate. During the rotation of the connecting disc, the sludge scraper moves on the inner wall of the dewatering screen cylinder, preventing the sludge from sticking to the inner wall of the dewatering screen cylinder and affecting its dewatering effect.

[0013] Furthermore, limit rings are provided at the upper end of the first locking hole and the lower end of the second locking hole;

[0014] Note: By setting a limit ring, the positioning accuracy when the chuck engages with the first and second locking holes can be improved.

[0015] Furthermore, a rubber buffer pad is provided at the top of the excitation rod; a buffer spring is fitted on the guide column and is grounded to the bottom surface of the first turntable;

[0016] Note: By setting up rubber buffer pads and buffer springs, it is helpful to reduce the noise generated during equipment operation.

[0017] Furthermore, a screw conveyor is horizontally installed at the bottom of the equipment box; the mud discharge pipe is connected to the screw conveyor via a threaded hose;

[0018] Note: Since the viscosity of mineral-containing sludge increases after dewatering, a screw conveyor is used to facilitate the rapid discharge of concentrated sludge from inside the dewatering screen cylinder, thereby improving the working efficiency of the equipment.

[0019] The method of using this utility model is as follows:

[0020] The mineral-containing sludge is fed into the dewatering screen cylinder through the feed hole. The position of the push seat is adjusted by the adjusting screw so that the push seat pulls the chuck and engages with the first locking hole. Then, the drive motor drives the first connecting frame and the dewatering screen cylinder to rotate simultaneously to centrifuge and dewater the mineral-containing sludge. The water in the mineral-containing sludge is discharged through the drain pipe.

[0021] The vibrating rod on the vibrating motor drives the dewatering screen cylinder to vibrate at high frequency along the guide column, causing the minerals in the mineral-containing sludge to be deposited at the bottom of the dewatering screen cylinder under the action of vibration; at the same time, it promotes the further precipitation of wastewater in the mineral-containing sludge.

[0022] The screw conveyor discharges the mineral-containing sludge after dewatering and concentration from the dewatering screen cylinder. Initially, the screw conveyor discharges a large amount of minerals, which are collected separately. During the sludge discharge process, the adjusting screw is used to adjust the push seat, so that the chuck engages with the second locking hole. The drive motor drives the connecting plate to rotate, and during the rotation of the connecting plate, the sludge scraper moves on the inner wall of the dewatering screen cylinder.

[0023] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0024] First, this utility model improves the dewatering effect of mineral-containing sludge by centrifugal dewatering and high-frequency vibrating screening, and also facilitates the screening and collection of minerals in the mineral-containing sludge, thus realizing the reduction and resource utilization of mineral-containing sludge.

[0025] Secondly, this utility model utilizes a single motor to drive the rotation of the dewatering screen cylinder, as well as the rotation of the connecting disc and sludge scraper inside the dewatering screen cylinder, which not only reduces the energy consumption of the equipment but also improves its working efficiency.

[0026] Third, by incorporating wheels, this invention allows for free movement of the equipment as the processing site changes, thus improving its ease of use. Attached Figure Description

[0035] like Figure 1 As shown, the first turntable 20 and the second turntable 21 are respectively rotatably engaged at the upper and lower ends of the outer side wall of the dewatering screen cylinder 2.

[0037] Example 2

[0038] The difference between this embodiment and Embodiment 1 is that:

[0040] By incorporating the walking wheels 12, the equipment can be easily moved, thus improving its ease of use.

[0041] Example 3

[0043] like Figure 5As shown, a connecting plate 5 is rotatably engaged inside the dewatering screen cylinder 2 and below the first connecting frame 22.

Thus, the drive motor 3 can not only drive the dewatering screen cylinder 2 to rotate and centrifuge the mineral-containing sludge for dewatering, but also drive the connecting plate 5 to rotate. During the rotation of the connecting plate 5, the sludge scraper 50 moves on the inner wall of the dewatering screen cylinder 2, preventing the sludge from sticking to the inner wall of the dewatering screen cylinder 2 and affecting its dewatering effect.

[0056] like Figure 1 As shown, a screw conveyor 6 is horizontally installed at the lower end of the equipment box 1; the mud discharge pipe 23 is connected to the screw conveyor 6 through a threaded hose.

[0057] Since the viscosity of mineral-containing sludge increases after dewatering, the screw conveyor 6 facilitates the rapid discharge of concentrated sludge from inside the dewatering screen cylinder 2, thereby improving the working efficiency of the equipment.

[0058] It should be noted that the drive motor 3, the excitation motor 4, and the screw conveyor 6 used in this utility model all adopt existing technologies and are not specifically limited here. Appropriate products can be selected according to actual needs.
