[0021] Beneficial effects

[0022] This invention provides a circulating water washing and impurity removal device for coal mining, which has the following advantages compared with the prior art:

[0023] 1. The washing mechanism can spray and clean the coal ore located in the feeding mechanism. At the same time, the motor can drive two eccentric wheels to rotate horizontally through the rotating shaft A. The eccentric wheels drive the guiding component to guide the coal ore into the feeding screen plate. Meanwhile, the two eccentric wheels alternately push the feeding screen plate to swing around the rotating shaft B as the central axis. The swinging rotating shaft B throws the coal ore on it in a parabolic motion to ensure that the coal ore is in full contact with the cleaning liquid. At the same time, the eccentric wheels push the slider through the feeding screen plate to squeeze the elastic element and use the elasticity of the elastic element to make the feeding screen plate shake. This makes the coal ore located in the feeding screen plate flow along the inclined direction of the feeding screen plate, so as to achieve the technical effect of uniform circulating water washing of the coal ore.

[0024] 2. The eccentric wheel can use the push rod on it to push the push rod to perform reciprocating linear motion in the vertical direction. The push rod pushes the sliding column to press against the spiral groove, causing the spiral rod to rotate in the vertical direction in the hopper, so as to achieve the technical effect of continuously feeding coal ore into the feed screen plate.

[0025] 3. The sliding rod can use the hinge plate to push the arc-shaped receiving plate to shake horizontally, quickly exporting the coal slag left on the screen plate B. It can also shake out the coal slag that clogs the mesh. It filters and intercepts the coal slag carried away by the coal ore after it has been washed by the water washing mechanism, preventing resource waste. At the same time, it can reintroduce the washed liquid into the water washing mechanism for recycling. Attached Figure Description

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] Please see Figures 1-5 According to one embodiment of the present invention, a circulating water washing and impurity removal device for coal mining includes a device body 1, a hopper 2, and a water washing mechanism 3. The hopper 2 is fixedly connected to the device body 1, and further includes:

[0035] The material feeding mechanism is connected to the device body 1 and is used to transport coal ore. The material feeding mechanism includes a material feeding screen 4, a pushing component 5 and a connecting component 8. The material feeding screen 4 is placed at an angle.

[0036] The material guiding component 6 is connected to the device body 1 and is used to guide the coal ore into the feeding mechanism;

[0037] The connecting assembly 8 includes a slide rod 801, a rotating shaft B802, and a slider 803. The two rotating shafts B802 are located at both ends of the slide rod 801 and are fixedly connected to the slide rod 801. The rotating shafts B802 are rotatably connected to the blanking screen plate 4. A return spring (not shown in the figure) is provided between the rotating shafts B802 and 4. One slide rod 801 is fixedly connected to the slider 803, and the other slide rod 801 is slidably engaged with the device body 1. The slider 803 is slidably engaged with the device body 1. The slider 803 is fixedly connected to the device body 1 through an elastic element 804.

[0038] The pushing component 5 includes a rotating shaft A501 and two eccentric wheels 502. The two eccentric wheels 502 are centrally symmetrically distributed on the rotating shaft A501 and are both fixedly connected to the rotating shaft A501. The rotating shaft A501 is rotatably connected to the device body 1. The rotating shaft A501 is connected to a motor (not shown in the figure) fixedly connected to the device body 1 through a coupling (not shown in the figure). The eccentric wheels 502 are connected to the material guiding component 6 through the transmission component 9.

[0039] Preferably, the elastic element 804 is any one of a spring, a compression spring, and an elastic steel plate.

[0040] Preferably, the discharge screen 4 is any one of an arc-shaped screen, a V-shaped screen, and a C-shaped screen. The purpose of this arrangement is to prevent the coal ore inside from falling out of the discharge screen 4 when it is being thrown.

[0041] Preferably, the feed screen 4 is detachably connected to a guide plate (not shown in the figure) via a bolt assembly (not shown in the figure), and the guide plate passes through the device body 1. The purpose of this arrangement is to guide the coal ore located on the feed screen 4 out of the device body 1 and prevent the coal ore from spilling into the gap between the feed screen 4 and the device body 1.

[0042] In this embodiment of the invention, the washing mechanism 3 can spray and clean the coal ore located in the feeding mechanism. At the same time, the motor can drive two eccentric wheels 502 to rotate horizontally through the rotating shaft A501. The eccentric wheels 502 drive the guiding component 6 to guide the coal ore into the feeding screen plate 4. Meanwhile, the two eccentric wheels 502 alternately push the feeding screen plate 4 to swing around the rotating shaft B802 as the central axis. The swinging rotating shaft B802 throws the coal ore on it in a parabolic motion to ensure that the coal ore is in full contact with the cleaning liquid. At the same time, the eccentric wheels 502 push the slider 803 through the feeding screen plate 4 to squeeze the elastic element 804 and use the elasticity of the elastic element 804 to make the feeding screen plate 4 shake. This makes the coal ore located in the feeding screen plate 4 flow along the inclined direction of the feeding screen plate 4, thereby achieving the technical effect of uniform circulating water washing of the coal ore.

A mesh plate B (not shown in the figure) is embedded and fixedly connected to the arc-shaped receiving plate 702. The purpose of this arrangement is that the slide rod 801 can use the hinge plate 701 to push the arc-shaped receiving plate 702 to shake horizontally, quickly exporting the coal slag retained on the mesh plate B, and shaking out the coal slag clogging the mesh.

[0045] In this embodiment of the invention, the purpose of this arrangement is to filter and retain the coal slag carried away by the coal washing mechanism 3 after the coal ore is washed, so as to prevent waste of resources, and at the same time, the liquid after washing can be reintroduced into the washing mechanism 3 for recycling.

[0046] Please see Figure 1 , Figure 2 as well as Figure 5 In one embodiment of the present invention, the material guiding assembly 6 includes a spiral rod 601 and a support B602. The spiral rod 601 is rotatably connected to the support B602, and the support B602 is fixedly connected to the hopper 2. The spiral rod 601 is connected to the eccentric wheel 502 through a transmission assembly 9. The transmission assembly 9 includes a shaped annular groove 901, a push rod 902, and a sliding column (not shown in the figure). The shaped annular groove 901 is formed on the eccentric wheel 502. The push rod 902 is slidably engaged with the shaped annular groove 901. The sliding column is fixedly connected to the push rod 902. The push rod 902 is slidably engaged with the spiral groove (not shown in the figure) formed in the spiral rod 601.

[0047] Preferably, the spiral groove is a reciprocating spiral groove. The purpose of this arrangement is to enable the spiral rod 601 to rotate in the same direction under the reciprocating push of the slide column, so as to continuously feed the coal ore into the feeding mechanism.

[0048] In this embodiment of the invention, the eccentric wheel 502 uses the push rod 902 on it to push the push rod 902 to perform reciprocating linear motion in the vertical direction. The push rod 902 pushes the sliding column to press against the spiral groove, causing the spiral rod 601 to rotate in the vertical direction in the hopper 2, thereby achieving the technical effect of continuously feeding coal ore into the feed screen plate 4.

[0049] Please see Figures 1-2 As an embodiment of the present invention, the water washing mechanism 3 includes a water tank 301 and a spray nozzle 303. The water tank 301 is fixedly connected to the device body 1, and further includes:
