It combines a drum-type structure with a pulse structure to achieve dewatering of tailings, solve the problem of easy clogging of screen holes, and also solve the problem of easy splashing.

[0009] To solve the above technical problems, the present invention adopts the following technical solution:

[0010] A high-efficiency dry discharge device for gold ore beneficiation includes a feed cylinder, a screen cylinder, and a discharge cylinder that are fixedly connected in sequence. The axes of the feed cylinder, screen cylinder, and discharge cylinder are collinear, and the screen cylinder is installed inside a cover. A blowpipe is provided at the top of the inner cavity of the cover. The blowpipe is parallel to the screen cylinder, and a row of blow holes is provided at the bottom of the blowpipe, with the blow holes facing the screen holes of the screen cylinder. The cover is fixedly installed on a swing frame, which is installed on the top of the machine frame.

[0011] Furthermore, the bottoms of the feed cylinder and the discharge cylinder are respectively supported by rollers for rotation.

[0012] Furthermore, a gear set is provided on the outside of the discharge cylinder, and the gear set is driven by a motor. The motor provides power for the rotation of the feed cylinder, screen cylinder and discharge cylinder.

[0013] Furthermore, the middle of the blowpipe is connected to a high-pressure gas cylinder via a pipeline, and a pulse valve is installed on the pipeline.

[0014] Furthermore, the screen cylinder is fixedly installed with multiple ribs distributed in a circular pattern.

[0015] Furthermore, a drain port is provided on one side of the bottom of the cover.

[0016] Furthermore, hinge supports a and b are fixed at the bottom of both ends of the swing frame along the length direction.

[0017] Furthermore, hinge support a is hinged to the top of the frame.

[0018] Furthermore, the hinge support b is hinged to the head of the hydraulic cylinder, and the tail of the hydraulic cylinder is hinged to the frame.

[0019] Furthermore, the hydraulic cylinder is set at an angle.

[0020] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0021] The slurry is centrifuged inside the screen cylinder to convert it into low-moisture dry material. The compressed air stored in the high-pressure gas cylinder is released by the pulse valve, and the generated high-pressure pulse air is blown along the blow holes to the screen holes of the screen cylinder to clear the blockages in the screen holes and maintain the centrifugal processing efficiency of the screen cylinder for the slurry.

[0022] By inserting the sieve cylinder inside the casing, the problem of splashing can be solved, thus preventing contamination.

[0023] In this invention, the inclination angles of the feed cylinder, screen cylinder, and discharge cylinder can be flexibly adjusted by hydraulic cylinders to ensure smooth material flow.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a high-efficiency dry discharge equipment for gold ore beneficiation, including a feed cylinder 1, a screen cylinder 2 and a discharge cylinder 3 that are fixedly connected in sequence. The axes of the feed cylinder 1, the screen cylinder 2 and the discharge cylinder 3 are arranged collinearly, and the screen cylinder 2 is installed inside the cover 8.

[0030] The bottoms of the feed cylinder 1 and the discharge cylinder 3 are respectively supported by rollers 4 for rotation.

[0031] The discharge cylinder 3 is equipped with a gear set 5, which is driven by a motor. The motor provides power for the rotation of the feed cylinder 1, screen cylinder 2, and discharge cylinder 3. During rotation, the screen cylinder 2 centrifuges the slurry with high water content to convert it into dry material with low moisture content.

[0032] The top of the inner cavity of the cover 8 is provided with a blow pipe 9, which is arranged parallel to the screen cylinder 2. The bottom of the blow pipe 9 is provided with a row of blow holes, which are arranged facing the screen holes of the screen cylinder 2.

[0033] The middle of the blow pipe 9 is connected to the high-pressure gas cylinder 10 via a pipeline, and a pulse valve 11 is installed on the pipeline.

[0034] The pulse valve 11 releases the compressed air stored in the high-pressure gas cylinder 10, so that the generated high-pressure pulse air is blown along the blow hole to the screen hole of the screen cylinder 2 to clear the blockage in the screen hole and maintain the centrifugal processing efficiency of the screen cylinder 2 for the slurry.

[0035] The screen cylinder 2 has multiple ribs fixedly installed inside in a circular pattern to improve its strength.

[0036] The bottom side of the cover 8 is provided with a drain port 15.

[0037] The cover 8 is fixedly installed on the swing frame 6, which is installed on the top of the frame 7. The swing frame 6 is used to adjust the tilt angle of the feed cylinder 1, the screen cylinder 2, and the discharge cylinder 3.

[0038] The swing frame 6 has hinge supports a12 and b14 fixed at its bottom ends along its length. Hinge support a12 is hinged to the top of the frame 7, and hinge support b14 is hinged to the head of the hydraulic cylinder 13. The hydraulic cylinder 13 is inclined, and its tail is hinged to the frame 7. The hydraulic cylinder 13 provides power for adjusting the inclination angle of the feed cylinder 1, screen cylinder 2, and discharge cylinder 3.

[0039] The specific working principle of this utility model is as follows:

[0040] The motor drives the feed cylinder 1, screen cylinder 2 and discharge cylinder 3 to rotate through the gear set 5. At the same time, the slurry with high water content enters the screen cylinder 2 through the feed cylinder 1. The slurry is centrifuged in the screen cylinder 2 and converted into low-moisture dry material before being discharged from the discharge cylinder 3.

[0041] In this invention, the pulse valve 11 releases the compressed air stored in the high-pressure gas cylinder 10, and the generated high-pressure pulse air is blown along the blow hole to the screen hole of the screen cylinder 2 to remove the blockage in the screen hole and maintain the centrifugal processing efficiency of the screen cylinder 2 for the slurry.

[0042] In this invention, the inclination angles of the feed cylinder 1, screen cylinder 2, and discharge cylinder 3 can be flexibly adjusted by the hydraulic cylinder 13 to ensure smooth material flow.

[0043] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
