Technical Field

[0002] Thickeners are suitable for dewatering concentrates and tailings in mineral processing plants and are widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection and other industries. High-efficiency thickeners are not simply sedimentation equipment, but a new type of dewatering equipment that incorporates the filtration characteristics of mud layers.

[0003] Currently, due to the large size and depth of thickeners, operators can only measure limited depth visually or with simple manual tools during daily production. Furthermore, working on the thickener is affected by time and weather conditions, posing certain dangers. Therefore, there is a need for a method that allows workers to observe the sludge depth from a safe area without needing to be directly above the thickener. This application proposes a sludge layer thickness detection mechanism for thickeners. Utility Model Content

[0004] The purpose of this invention is to provide a mud layer thickness detection mechanism for a thickener, addressing the problems mentioned in the background art where thickeners are large in size and deep, and in daily production, operators can only measure limited depths visually or with simple manual tools. Furthermore, working on the thickener is subject to the influence of time and weather, posing certain dangers to the work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mud layer thickness detection mechanism for a thickener, comprising a thickener body, wherein an operating platform is provided on the top of the thickener body; The operating platform is equipped with a detection base, a rotating frame that rotates with the detection base, a power device for providing rotational thrust to the rotating frame, a detection bracket mounted on the rotating frame, a telescopic unit mounted on the detection bracket, and a detection rod connected to the output end of the telescopic unit. The detection rod has at least two states, including a detection state and a reading state; The operating platform is equipped with a reference ruler and a detection device. When the detection rod is in the reading state, the detection rod and the reference ruler are parallel, and the detection device is aligned with the detection rod and the reference ruler. When the detection rod is in the detection state, the detection rod is vertically downward.

[0006] Preferably, the concentrator body is provided with a mixing mechanism, which includes a driving device, a rotating roller connected to the driving device, and a push plate mounted on the rotating roller.

[0007] Preferably, four push plates are provided, and the four push plates are arranged in a circumferential array around the center line of the rotating roller.

[0008] Preferably, the bottom of the storage tank in the concentrator body is provided with an inclined section, and the push plate has the same inclination angle as the inclined section.

[0009] Preferably, the push plate is provided with a plurality of vertically distributed auxiliary plates.

[0010] Preferably, the bottom of the detection rod is provided with an arc-shaped part, which fits into the inner wall of the storage tank inside the concentrator.

[0015] Beneficial effects: I. This utility model provides a mud layer thickness detection mechanism for a thickener. The power unit can drive the tilting frame to rotate around the detection base, thereby allowing the detection rod to switch between two states: detection state and reading state. When the detection rod is in the detection state, the telescopic unit connected to the detection rod can drive the detection rod to move down and insert it into the thickener body, eventually pressing it against the inner wall of the thickener body. The sludge leaves an imprint on the detection rod. The telescopic unit then pulls the detection rod out of the sludge. Afterward, the power unit switches the detection rod to the reading state. In this state, the length of the imprint is read, and the imprint length is the depth of the sludge. In this way, the depth of the sludge inside the thickener body can be easily obtained, allowing workers to view the sludge depth in a safe area.

[0016] II. The present invention provides a mud layer thickness detection mechanism for a thickener. The cooperation of components such as a water tank and a power pump allows the power pump to be turned on after the reading of the detection rod is taken, so that water in the water tank can be sprayed out through the nozzle. This can clean the detection rod and wash away the silt adhering to the detection rod. The cleaned detection rod can be used for subsequent silt depth detection. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0020] like Figures 1-6 As shown in the figure, the present invention provides a mud layer thickness detection mechanism for a thickener, including a thickener body 1, and an operating platform 2 is provided on the top of the thickener body 1.

[0021] Thickeners are suitable for dewatering concentrates and tailings in mineral processing plants and are widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection and other industries. High-efficiency thickeners are not simply sedimentation equipment, but rather dewatering equipment that incorporates the filtration characteristics of mud layers. In mines, the thickener body 1 needs to process waste generated during the mining process, separating impurities such as sludge from the wastewater.

[0022] In order to accelerate the dehydration speed of the material inside the thickener body 1, a mixing mechanism 14 is provided inside the thickener body 1. The mixing mechanism 14 includes a driving device, a rotating roller connected to the driving device, and a push plate installed on the rotating roller. The driving device can drive the rotating roller to rotate, thereby driving the push plate to rotate, stirring the material inside the thickener body 1, so that the material is dehydrated evenly.

[0023] Specifically, there are four push plates, which are arranged in a circumferential array around the center line of the rotating roller. The bottom of the storage tank in the concentrator body 1 is provided with an inclined part. The push plates are inclined at the same angle as the inclined part, and several vertically distributed auxiliary plates are provided on the push plates.

[0024] Specifically, the operating platform 2 is equipped with a detection base 3, a tilting frame 4 that rotatably engages with the detection base 3, a power device for providing rotational thrust to the tilting frame 4, a detection bracket 5 mounted on the tilting frame 4, a telescopic unit 6 mounted on the detection bracket 5, and a detection rod 7 connected to the output end of the telescopic unit 6. It should be noted that the detection base 3 and the tilting frame 4 can be rotatably engaged via a rotating shaft. The power device can be a motor, which drives the rotating shaft to rotate. The rotating shaft is connected to the tilting frame 4, thus allowing adjustment of the angles of the tilting frame 4, the telescopic unit 6, and the detection rod 7. The telescopic unit 6 can be a cylinder.

[0025] The power unit can drive the telescopic unit 6 and the detection rod 7 to rotate, thereby adjusting the orientation of the detection rod 7 so that the detection rod 7 has at least two states, including detection state and reading state.

[0026] To facilitate the reading of depth values ​​when the detection rod 7 is in the reading state, a reference ruler 9 and a detection device 8 are installed on the operating platform 2. The detection device 8 can be a camera. When the detection rod 7 is in the reading state, the detection rod 7 and the reference ruler 9 are parallel, and the detection device 8 is aligned with the detection rod 7 and the reference ruler 9. When the detection rod 7 is in the detection state, the detection rod 7 is vertically downward. The camera is wirelessly connected to an external computer, which allows users to view the images captured by the camera and read the length of the mark on the detection rod 7.

[0027] The power unit can drive the tilting frame 4 to rotate around the detection base 3, thereby allowing the detection rod 7 to switch between detection and reading states. When the detection rod 7 is in the detection state, the telescopic unit 6 connected to the detection rod 7 can drive the detection rod 7 to move down and insert it into the inside of the thickener body 1, and finally abut against the inner wall of the thickener body 1. The sludge leaves an imprint on the detection rod 7. The telescopic unit 6 is used to pull the detection rod 7 out of the sludge. Then, the power unit switches the detection rod 7 to the reading state. In this state, the length of the imprint of the detection rod 7 is read. The imprint length is the depth of the sludge. In this way, the depth of the sludge inside the thickener body 1 can be easily obtained.

[0028] The cylinder can be a piston cylinder. The stroke of the piston cylinder can be adjusted by adjusting the bolts on it. By adjusting the bolts, the detection rod 7 can be pressed against the inner wall of the concentrator body 1 when the stroke is at its maximum. The above stroke adjustment has a length limit, so it is necessary to select a cylinder with a suitable stroke. Other control methods can also be used.

[0029] It should be noted that the bottom of the detection rod 7 is provided with an arc-shaped part, which cooperates with the inner wall of the storage tank inside the concentrator body 1, that is, the arc-shaped part can eventually be inserted into the position that abuts against the inner wall of the concentrator body 1.

[0030] It should be added that when the detection rod 7 is in the detection state, the end of the detection rod 7 furthest from the telescopic unit 6 is tilted downwards, and the reference ruler 9 is distributed parallel to the detection rod 7. The downward tilt of the end of the detection rod 7 furthest from the telescopic unit 6 prevents the silt adhering to the detection rod 7 from flowing away during the detection process, thus preventing the silt from flowing into areas not adhered to by the silt. This also makes readings easier to identify.

[0031] In order to clean the detection rod 7 with adhering silt, a water tank 10, a power pump connected to the water tank 10, a delivery pipe 11 connected to the power pump, and a nozzle 12 connected to the delivery pipe 11 are provided on the operating platform 2. There are two nozzles 12. When the detection rod 7 is in the reading state, the two nozzles 12 are symmetrically distributed around the center line of the detection rod 7. The opening of the nozzle 12 faces the detection rod 7 and is located above the detection rod 7. A mounting bracket 13 for installing the reference ruler 9 is provided on the outer wall of the water tank 10.

[0032] The water tank 10, power pump and other components work together so that after the reading of the detection rod 7 is taken, the power pump can be turned on to spray water from the water tank 10 through the nozzle 12. This can clean the detection rod 7 and wash away the silt adhering to it. The cleaned detection rod 7 can be used for subsequent silt depth detection.

[0033] In summary, this utility model embodiment provides a mud layer thickness detection mechanism for a thickener. The power unit can drive the tilting frame 4 to rotate around the detection base 3, thereby allowing the detection rod 7 to switch between detection and reading states. When the detection rod 7 is in the detection state, the telescopic unit 6 connected to the detection rod 7 can drive the detection rod 7 to move downwards and insert it into the thickener body 1, eventually abutting against the inner wall of the thickener body 1. The sludge leaves an imprint on the detection rod 7. The telescopic unit 6 is used to pull the detection rod 7 out of the sludge. Then, the power unit switches the detection rod 7 to the reading state. In this state, the length of the imprint of the detection rod 7 is read, and the imprint length is the depth of the sludge. In this way, the depth of the sludge inside the thickener body 1 can be easily obtained.

[0034] The water tank 10, power pump and other components work together so that after the reading of the detection rod 7 is taken, the power pump can be turned on to spray water from the water tank 10 through the nozzle 12. This can clean the detection rod 7 and wash away the silt adhering to it. The cleaned detection rod 7 can be used for subsequent silt depth detection.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
