[0022] like Figure 1 As shown, the ore screening device with flushing according to the embodiment of the present application comprises a screening device 10 and a flushing device 20 disposed in the screening device 10;

[0023] Each flushing device 20 includes a longitudinal support 40, a transverse support 401, a water flushing pipe 201 and a first water spray port 203;

[0024] The longitudinal support is arranged above the screening device along the conveying direction of the ore on the screening device; the transverse support includes two groups, which are arranged at both ends of the longitudinal support; the water washing pipe includes two groups, which are arranged under the two groups of transverse supports;

[0025] The first water spraying ports are arranged on the water washing pipes; the spraying directions of the first water spraying ports on the two groups of water washing pipes are opposite.

[0026] In this example, a ore screening device with flushing of the utility model is provided. The longitudinal bracket and two groups of transverse brackets are cross-arranged to form a relative position, which is used to set two groups of relative water washing pipes. The first water spraying ports thereon spray in opposite directions, so that the ore thereon can be washed on both sides to achieve the best washing effect. The device is used to wash ore, especially to wash the tailings waste rock after sorting during the screening process, and can fully recover the mineral powder wrapped on the waste rock. Under the purpose of achieving the purpose of pre-waste disposal, the recovery rate of beneficial components is guaranteed, thereby avoiding the blockage of the screen and the waste of ore raw materials, and greatly improving the economic benefits of the enterprise.

[0027] In one embodiment, the screening device 10 is a linear vibrating screen, which occupies less space, has a good screening effect, and is convenient for arranging the flushing device 20. For example, Figure 1 As shown, the screening device includes a feed port and a conveying device. The ore falls onto a conveyor belt such as a belt through the feed port at a certain height for washing.

[0028] In one embodiment, the first water spraying ports on each group of water washing pipes are arranged at equal distances, and the first water spraying ports on the two groups of water washing pipes are arranged in staggered positions.

[0029] In this embodiment, the arrangement of the first water spraying ports is provided, and the arrangement is equidistant and staggered, so that the first water spraying ports on two adjacent water washing pipes are installed opposite to each other and facing the air, and the spraying directions are opposite, which can ensure that the washing surface is not missed, thereby ensuring the recovery rate of the beneficial components to a great extent. More preferably, the first water spraying port can be selected as a high-pressure water spraying port.

[0030] In one embodiment, the flushing device 20 includes a plurality of groups, which are spaced apart from top to bottom, and blocking members 30 are spaced apart between the flushing devices.

[0031] In this embodiment, the flushing device 20 includes multiple groups. By arranging multiple groups of flushing devices 20 to flush the waste rock multiple times, the recovery rate of the beneficial components of the tailings waste rock can be greatly improved. More importantly, a blocking member 30 is arranged between them, which can enable the ore to be turned over multiple times due to the impact of resistance during transportation, thereby ensuring that the waste rock is flushed in all directions. In one embodiment, the blocking member 30 is an angle steel with a length consistent with the width of the screening device 10, and the angle steel is installed in the vertical middle position of the screening device 10. The blocking member of the above-mentioned structural form has a simple structure, is easy to install and arrange, and is stable and reliable.

[0032] In one embodiment, the flushing device 20 includes two groups, which are respectively arranged at the front end and the rear end of the screening device 10 ; and the blocking member is arranged in the middle of the screening device 10 .

[0033] In this embodiment, if Figure 1 As shown, the flushing device 20 includes two groups, which are respectively arranged at the front end and the rear end of the screening device 10. When the ore enters the screening device, it can be flushed once, and after the blocking member 30 is turned over, the other side can be flushed twice, so that the cleaning is more complete. More specifically, since the ore on the screening device is continuously transported, the two groups of flushing devices 20 can be operated simultaneously to flush the ore on the screening device at different positions; or they can be controlled separately at intervals to flush the ore at fixed points at regular intervals.

[0034] In one embodiment, a water washing pipe 201 is extended to the feed inlet 101 of the screening device 10, and a second water spraying port 205 is provided at the outlet of the water washing pipe 201, and the spraying direction of the second water spraying port 205 is toward the feed inlet 101 of the screening device 10. More preferably, the water washing pipe extended to the screening device 10 can be opened from a baffle on one side of the screening device belt, so that no additional baffle needs to be installed, and it can also play a supporting role.

[0035] In this embodiment, by providing a second water spray port 205 above the feed port 101 of the screening device 10, the waste rock can be pre-washed to improve the recovery rate of the beneficial components. More preferably, the second water spray port can be a high-pressure water spray port.

[0036] In one embodiment, the first water spray port 203 and the second water spray port 205 are both provided with duckbill nozzles 207, so that the flushing water of the nozzles 207 is sprayed in a fan shape. Specifically, the nozzles 207 are polyurethane duckbill nozzles, and when spraying, the spraying water is fan-shaped, and the flushing effect is good.

[0037] In one embodiment, a main water pipe is provided outside the screening device 10 , and the main water pipe is divided into at least two branch pipes. Each branch pipe is divided into at least two water washing pipes 201 after entering the screening device, and is arranged on a transverse bracket 401 .

[0038] In this embodiment, by providing a main water pipe connected to multiple groups of branch pipes to provide multiple groups of water washing pipes 201, the structural compactness of the flushing device 10 can be further improved.

[0039] In one embodiment, on each set of flushing devices, the spacing between two adjacent sets of water washing pipes 201 is 50-60 mm. Specifically, setting the spacing between two adjacent water washing pipes 201 within the above range can ensure stable and reliable tumbling flushing of waste rocks.

[0040] The working process of the ore screening device in the embodiment of the present application is as follows:

[0041] When the ore enters the screening device 10 through the feed port 101 of the screening device 10, the flushing water of the duckbill nozzle 207 at the second water spray port 205 above the feed port 101 is sprayed in a fan shape to pre-wash the waste rock. During the screening and moving process of the linear vibrating screen, when the ore moves to the middle of the first group of horizontal supports 401, the water in the water washing pipe 201 washes the ore again through the nozzle 207. After being turned over by the blocking member 30, when it moves to the middle of the second group of horizontal supports 401, the water in the water washing pipe 201 washes the other side of the ore again through the nozzle 207 to remove impurities and fully recover the powder ore wrapped on the ore. While achieving the purpose of pre-waste disposal, the recovery rate of beneficial components is guaranteed, the utilization rate of the ore is improved, and the economic benefits are increased.

[0042] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
