Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a coal washing feeding device. Background Art

[0002] Coal washing is the process of removing impurities from raw coal through physical and chemical methods to make it purer. Coal washing is an indispensable part of coal processing, which can not only improve the utilization rate of coal, but also achieve the purpose of environmental protection.

[0003] At present, in the coal washing process, the feeding device plays a key role in connecting the coal washing equipment and the raw coal conveying system. It undertakes the important task of accurately feeding the raw coal into the coal washing equipment, thereby ensuring the continuity and stability of the entire coal washing process. The feeding device generally adopts a funnel-shaped design, because the top of the funnel is designed with a wide opening, so that the material from the upstream conveying equipment can enter it easily and smoothly. As the material moves to the bottom of the funnel, its opening gradually narrows, cleverly guiding the material into the coal washing equipment, ensuring the continuity and stability of the material flow.

[0004] However, although the existing feeding device can effectively guide the raw coal into the coal washing equipment, the raw coal after mining is simply crushed and its particle size varies, which brings challenges to the feeding process. Larger raw coal particles are often easily blocked at the bottom of the feeding device, resulting in poor feeding, which in turn affects the efficiency of the entire coal washing process. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, one purpose of the utility model is to provide a coal washing feeding device, which successfully reduces the blockage of the feeding port by crushing the raw coal blocking the feeding port, thereby improving the feeding efficiency during the coal washing process.

[0008] The utility model discloses a coal washing feeding device. During the process of coal washing feeding, a feeding box is placed under a raw coal conveying device with the aid of a bracket. The raw coal is discharged into a crushing assembly through the feeding box. Driven by a driving mechanism, the movable end of a crushing plate continuously swings, and with the aid of crushing teeth and a fixed end, the larger raw coal is crushed. Meanwhile, vibration is generated under the swing of the movable end of the crushing plate, so that the raw coal is prevented from accumulating in the crushing assembly and causing blockage. The blockage of the discharge port of the feeding device is successfully reduced by crushing the raw coal. Thus, the feeding efficiency during the coal washing process is improved.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The coal washing unloading device of the utility model embodiment is described below with reference to the accompanying drawings.

[0022] The coal washing feeding device provided in the embodiment of the utility model can be used for feeding during coal washing. By crushing the raw coal blocking the discharge port of the feeding device, the blockage phenomenon of the discharge port is successfully reduced, thereby improving the feeding efficiency during the coal washing process.

[0023] like Figure 1-Figure 3 As shown, the coal washing unloading device of the embodiment of the utility model may include a unloading box 1, a bracket 3, a crushing assembly 5, a driving mechanism 6 and a hinge frame 8.

[0024] It should be noted that the material box 1 is in the shape of a rectangular structure.

[0025] The bracket 3 is fixedly connected to the material box 1 .

[0026] It can be understood that the bracket 3 completes the support and installation of the unloading box 1 at the coal washing site.

[0027] The crushing assembly 5 is disposed below the lower material box 1 , and the crushing assembly 5 may include a crushing plate 51 and crushing teeth 52 .

[0028] It should be noted that the crushing teeth 52 are respectively arranged on opposite sides of the movable end and the fixed end of the crushing plate 51 .

[0029] The crushing plate 51 has a fixed end and a movable end, one side of the movable end is hinged to the discharge box 1 through a hinge frame 8 , and the crushing teeth 52 are fixedly connected to the crushing plate 51 .

[0030] It can be understood that the crushing of large pieces of raw coal is completed by squeezing the crushing teeth 52 on the movable end of the crushing plate 51 and the crushing teeth 52 on the fixed end, while avoiding the situation where the raw coal is too pulverized and dissolved in water during coal washing.

[0031] The driving mechanism 6 is installed on one side of the bracket 3 , and the driving mechanism 6 is hinged to the crushing plate 51 .

[0032] It should be noted that, under the drive of the driving mechanism 6, the movable end of the crushing plate 51 is driven to achieve the effect of crushing large pieces of raw coal.

[0033] Specifically, in the actual operation process, when the relevant personnel are cleaning and unloading the raw coal, they move the unloading box 1 to the top of the coal washing device and the bottom of the raw coal transmission device under the action of the bracket 3, and the raw coal enters the crushing assembly 5 through the unloading box 1. Under the drive of the driving mechanism 6, the crushing teeth 52 on the movable end of the crushing plate 51 and the crushing teeth 52 on the fixed end are squeezed to complete the crushing of large pieces of raw coal, while avoiding the situation that the raw coal after crushing is too crushed and dissolves in water during coal washing. At the same time, when the driving mechanism 6 drives the movable end of the crushing plate 51 to swing and crush the raw coal, the vibration generated will shake off the raw coal accumulated at the conical bottom of the unloading box 1, so as to further avoid the accumulation of raw coal during coal washing, and successfully reduce the blockage of the discharge port by crushing the raw coal blocking the discharge port of the unloading device, thereby improving the unloading efficiency during the coal washing process.

[0034] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the driving mechanism 6 may include a driving assembly 61 , an elliptical plate 62 , a mounting frame 63 , a spring 64 , a connecting rod 65 , a rotating frame 66 and a roller 67 .

[0035] It should be noted that the driving component 61 described in the above embodiment may be a driving motor.

[0036] Among them, the driving component 61 is detachably mounted on one side of the bracket 3, the elliptical plate 62 is fixedly connected to the output end of the driving component 61, the mounting frame 63 is fixedly connected to the bracket 3, the spring 64 is fixedly connected to the mounting frame 63, the connecting rod 65 is fixedly connected to one inner end of the spring 64, and the connecting rod 65 passes through the mounting frame 63 and the spring 64 and is hinged to the movable end of the crushing plate 51.

[0037] It should be noted that when the driving assembly 61 drives the elliptical plate 62 to rotate, the elliptical plate 62 abuts against the roller 67 and drives the roller 67 to rotate. At the same time, because the elliptical plate 62 has an elliptical structure, the roller 67 can only complete the swing of the movable end of the crushing plate 51 through the spring 64 when it contacts the two ends of the elliptical plate 62, thereby completing the effect of driving the movable end of the crushing plate 51.

[0038] The rotating frame 66 is fixedly connected to the spring 64 , the roller 67 is rotatably connected to the inner side of the rotating frame 66 , and the elliptical plate 62 is rollingly connected to the roller 67 .

[0039] It can be understood that, under the action of the spring 64 , it can be ensured that the roller 67 is always in contact with the elliptical plate 62 .

[0040] In one embodiment of the present invention, Figure 1-Figure 2 As shown, a blanking plate 2 is fixedly connected to the interior of the blanking box 1 .

[0041] It should be noted that there are two groups of blanking plates 2 which are arranged opposite to each other on the inner side of the blanking box 1 , and both groups of blanking plates 2 are arranged in an inclined state.

[0042] It can be understood that, under the action of the unloading plate 2, the raw coal is prevented from being directly discharged into the bottom of the unloading box 1 during unloading, thereby preventing the raw coal from being piled up.

[0043] In one embodiment of the present invention, Figure 1-Figure 2 As shown, a vibration motor 4 is installed on the top of the other side of the bracket 3.

[0044] It can be understood that, under the action of the vibration motor 4, the speed of unloading the raw coal at the bottom of the unloading box 1 and on the unloading plate 2 is further accelerated to avoid accumulation.

[0045] In one embodiment of the present invention, Figure 1-Figure 2 As shown, a sleeve assembly 7 is fixedly connected to the bottom of the bracket 3 , and the sleeve assembly 7 may include a support frame 71 and a cloth bag connecting pipe 72 .

[0046] As a possible situation, a cable tie may be installed on the outer side of the cloth bag connecting tube 72 to reinforce the connection of the cloth bag connecting tube 72 to the support frame 71 .

[0047] The support frame 71 is fixedly connected to the bracket 3 , and the bag connecting pipe 72 is sleeved on the outer side of the bottom of the support frame 71 .

[0048] It should be noted that the bag connecting pipe 72 is installed on the bottom outer side of the crushing plate 51 through the support frame 71, so as to avoid the diffusion of dust during the feeding and crushing of raw coal, ensure that the raw coal can be directly discharged into the coal washing device, and reduce the pollution of dust to the air.

[0049] In summary, in the coal washing and feeding device of the embodiment of the utility model, during the process of coal washing and feeding, the feeding box is placed under the raw coal conveying device with the assistance of the bracket, and the raw coal is discharged into the crushing assembly through the feeding box. Driven by the driving mechanism, the movable end of the crushing plate continuously swings, and with the assistance of the crushing teeth and the fixed end, the larger raw coal is crushed. At the same time, the swing of the movable end of the crushing plate generates vibration, which prevents the raw coal from accumulating in the crushing assembly and causing blockage. The blockage of the discharge port of the feeding device is successfully reduced by crushing the raw coal that blocks the discharge port, thereby improving the feeding efficiency during the coal washing process.
