Description

Technical Field

[0001] This utility model relates to the field of ore washing equipment technology, and in particular to an ore washing device. Background Technology

[0002] After initial crushing, the mined ore needs to be fed into a drum washing machine to remove the mud. The drum washing machine includes a connected washing section and a screening section. To facilitate the forward transport of the stone, spiral-shaped lifting plates are connected to the inner walls of both the washing and screening sections. Since the screening section needs to remove mud and sand, spray pipes are installed inside. During use, the applicant found that due to the lifting plates, the height of the spray pipes cannot be set too high, otherwise it will interfere with the spiral lifting plates. Furthermore, because the spray pipes are too low, the stone thrown down from the screening section hits the spray pipes and nozzles, severely reducing their service life. Improvements are needed. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide an ore washing device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An ore washing device includes a frame, a drum, and a drive mechanism. The drum is rotatably mounted laterally on the frame. The drive mechanism drives the drum to rotate. The drum includes a washing section and a screening section connected opposite each other. A water-blocking ring plate is connected to the side of the washing section away from the screening section. The inner wall of the washing section has several spiral lifting plates. The drum wall of the screening section has several screen holes evenly distributed. The inner diameter of the screening section gradually increases in the direction away from the washing section. A spray pipe is located at the top of the screening section and is connected to a water supply source. Several nozzles are evenly distributed at the bottom of the spray pipe.

[0006] Furthermore, a lifting plate is movably installed at the bottom of the screening section, and a reciprocating motor is installed outside the screening section. The reciprocating motor is fixed relative to the frame, and the main shaft of the reciprocating motor is coaxial with the screening section. A connecting arm is fixedly connected to the main shaft of the reciprocating motor, and the connecting arm is fixedly connected to the lifting plate. The reciprocating motor is used to drive the lifting plate to swing back and forth in the lower part of the screening section.

[0007] Furthermore, the lifting plate is elongated and fits against the inner wall of the screening section, and several protruding nails are evenly distributed on the top of the lifting plate.

[0008] Furthermore, the inner wall of the cleaning section is fitted with a hardened plate, and the spiral lifting plate is fixed to the hardened plate.

[0009] The beneficial effects of this utility model are as follows: by setting the inner wall of the screening section as a conical surface and reducing the spiral lifting plates in the screening section, the screening section can still feed materials outward even without spiral lifting plates. Furthermore, the position of the spray pipe can be installed higher, effectively preventing stones from hitting the spray pipe and spray head, and significantly extending the service life of the spray pipe.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0014] like Figures 1-2As shown, an ore washing device includes a frame, a drum 1, and a drive mechanism. The frame includes two spaced-apart roller frames 2. Two positioning rings 3 are sleeved on the outside of the drum 1. The drum 1 is horizontally mounted on the two roller frames 2 via the two positioning rings 3. The drive mechanism includes a drive motor 4, a gear 5, and a gear ring 6. The gear ring 6 is sleeved on the outside of the drum 1. The gear 5 is fixedly connected to the main shaft of the drive motor 4. The gear 5 meshes with the gear ring 6. The drive motor 4 is fixed relative to the two roller frames 2. The drum 1 includes a washing section 11 and a screening section 12 connected to each other. A water-blocking ring plate 111 is connected to the side of the washing section 11 away from the screening section 12. Spiral lifting plates 7 are evenly distributed on the inner wall of the washing section 11. A plurality of screen holes 121 are evenly distributed on the cylinder wall of the screening section 12. The inner wall of the screening section 12 is conical. The inner diameter of section 12 gradually increases in the direction away from the washing section 11. There is a spray pipe 8 at the top of the screening section 12. The spray pipe 8 is fixed relative to two roller frames 2. The spray pipe 8 is connected to a water supply source. Several nozzles are evenly distributed at the bottom of the spray pipe 8. A lifting plate 9 is movably installed at the bottom of the screening section 12. The lifting plate 9 is long and narrow and fits against the inner wall of the screening section 12. Several protruding nails 91 are evenly distributed at the top of the lifting plate 9. A reciprocating motor 10 is installed on the outside of the screening section 12. The reciprocating motor 10 is supported by a bracket. The bracket is fixed relative to the roller frames 2. The main shaft of the reciprocating motor 10 is coaxial with the screening section 12. A connecting arm 110 is fixedly connected to the main shaft of the reciprocating motor 10. The connecting arm 110 is fixedly connected to the lifting plate 9. The reciprocating motor 10 is used to drive the lifting plate 9 to swing back and forth in the lower part of the screening section 12.

[0015] In actual use, the ore is first put into the washing section 11, and then water is poured into the washing section 11. Under the action of the water baffle ring 111, the water can only flow into the screening section 12. The ore rolls fully in the washing section 11, which can wash away the mud and sand on the surface of the ore. The spiral lifter 7 can transport the ore forward to the screening section 12. When the ore arrives at the screening section 12, the spray pipe 8 can spray and wash the ore. The mud and dirty water are discharged through the screen hole 121, and the clean ore is discharged from the large diameter end of the screening section 12. The reciprocating motor 10 can drive the lifting plate 9 to swing back and forth, which can speed up the feeding speed of the ore and also turn the ore to improve the spraying effect.

[0016] In this embodiment, a hardened plate 120 is attached to the inner wall of the cleaning section 11, and the spiral lifting plate 7 is fixed to the hardened plate 120. This can effectively extend the strength of the cleaning section 11.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
