Description

Technical Field

[0001] This utility model belongs to the field of thickener technology, and in particular relates to a hydraulic lifting device for a thickener. Background Technology

[0002] The thickener mainly consists of two parts: a circular thickening tank and a rake scraper. In mineral processing plants, it is generally used for concentrate thickening or tailings dewatering before filtration. It can also be used for thickening and purifying solid slurries in industries such as coal, chemical, building materials, water source and sewage treatment. Sometimes, in order to increase the feed concentration of the next stage and improve the beneficiation effect, the middlings also need to be thickened during the beneficiation process. However, the rake bar is not easy to retract and is not convenient for feeding. Therefore, a foldable and retractable rake lifting device is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a hydraulic rake lifting device for a concentrator, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a hydraulic rake lifting device for a concentrator, comprising a housing and an adjusting component;

[0005] The adjusting assembly includes connecting rod A, connecting rod B, and a connecting block. The connecting block is fixedly connected to the bottom of the housing. One end of each of the two connecting rods A is hinged to connecting rod B via hinge seats on them. The other end of each of the two connecting rods B is hinged to the connecting block. The other end of each of the two connecting rods A is hinged to the slide cylinder via hinge seats on both sides of the slide cylinder. The slide cylinder is slidably connected to the housing via a slide rail inside the housing. The slide cylinder is threadedly connected to the screw on the screw rod. The screw rod is rotatably connected to the housing inside the housing.

[0006] Beneficial effects

[0007] This utility model provides a hydraulic rake lifting device for a concentrator, which has the following advantages compared with the prior art:

[0008] The relevant technicians start the motor, causing the gear meshing with its output gear to rotate. This gear then drives the screw fixedly connected to it to rotate synchronously. The screw then drives the threaded slide cylinder on it to move linearly along the slide rail connected to the housing. This causes the slide cylinder to drive the connecting rod A, which is hinged at both ends, to move synchronously. This causes the connecting rod A to push the connecting rod B, which is hinged to it, and the connecting rod B to move in a circular motion around the hinge point with the connecting block. When the connecting rod A is in a horizontal state, the motor is turned off, and processing begins. After processing is completed, the relevant technicians manually turn the rocker arm, causing the rocker arm to drive the lead screw fixedly connected to it to rotate synchronously. This causes the slide cylinder A, which is threaded to it, to move linearly along the slide rail connected to it with the crossbar. This causes the slide cylinder A to drive the pull rod hinged to it to move synchronously. This causes the pull rod to pull the housing, which is hinged to it, thus completing the deployment and retraction of the device. Attached Figure Description

[0028] Specifically, the housing 101 is hinged to the pull rod 209 via a hinge seat thereon, and the other end of the pull rod 209 is hinged to the slide cylinder A301 on the slide cylinder A301.

[0029] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific pull rod 209 described in the above embodiments. For example, the pull rod 209 should be made of a material that is integrally machined, and the hinges at both ends should be further hardened and reinforced.

[0034] In this embodiment of the invention, a person skilled in the art starts the motor 207, causing the motor 207 to drive the gear 206, which is meshed with its output gear, to rotate. This causes the gear 206 to drive the screw 205, which is fixedly connected to it, to rotate synchronously. The screw 205 then drives the threaded slide cylinder 204 to move linearly along the slide rail at its connection with the housing 101. This causes the slide cylinder 204 to drive the connecting rod A201, which is hinged at both ends, to move synchronously. This causes the connecting rod A201 to push the connecting rod B202, which is hinged to it, so that the connecting rod B202... The hinge 203 serves as the fulcrum for circular motion. When the connecting rod A201 is in a horizontal state, the motor 207 is turned off, thus starting the processing. After processing is completed, the relevant technicians manually rotate the rocker arm 303, causing the rocker arm 303 to drive the lead screw 302 fixedly connected to it to rotate synchronously. This causes the slide cylinder A301 threaded on the lead screw 302 to begin linear motion along the slide rail at its connection with the crossbar 208. This causes the slide cylinder A301 to drive the pull rod 209 hinged to it to move synchronously, thus causing the pull rod 209 to begin pulling the housing 101 hinged to it, thereby completing the retraction and extension of the device.
