Description

Technical Field

[0001] This utility model relates to the field of coal gangue aggregate screening technology, specifically to a coal gangue aggregate screening device. Background Technology

[0002] In the coal mining and related processing industries, coal gangue, as a byproduct of coal production, has a huge output. As a reusable resource, coal gangue aggregate has broad application prospects in many fields such as building materials and road engineering. In order to ensure that coal gangue aggregate can meet the quality requirements of different application scenarios, it is essential to perform effective screening treatment. Existing screening devices generally have an open feed end, which generates significant dust during the input of coal gangue aggregate. Furthermore, the fine aggregate particles screened out also tend to generate considerable dust during discharge, leading to severe environmental pollution and making cleaning difficult. The internal structure of existing screening devices typically only has a single screen plate, which can only screen out aggregate particles of a certain size. It cannot further refine the larger aggregate particles, requiring subsequent screening, resulting in low efficiency and considerable inconvenience. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing screening devices have an open feed end, resulting in a lot of dust during input and output of fine particles, which pollutes the environment and is difficult to clean; moreover, most of them have a single screen plate inside, which cannot finely screen large aggregates, requiring secondary screening, resulting in low efficiency and complicated operation.

[0004] To solve the above problems, the technical solution adopted by this utility model is a screening device for coal gangue aggregate, including a screening mechanism, a material guiding mechanism at the top of the screening mechanism, and a collection box located below the screening mechanism. The screening mechanism includes a screen box, a screen plate is obliquely fixed inside the screen box by screws, a guide plate is obliquely fixed above the screen plate, an opening one is opened on one side of the screen box at the bottom end of the guide plate, an opening two is opened at the bottom end of the screen box at the bottom end of the screen plate, and a discharge port is opened at the bottom end of the screen box. The material guiding mechanism includes a cover, and a connecting pipe is connected to the top of the cover through a corrugated pipe. A pair of hooks are fixed at one end of the connecting pipe. The hooks are hung on the side of the outer conveyor belt. A guide plate is fixed obliquely on the inner side of the cover above the guide plate to prevent the aggregate from falling directly onto the guide plate. A pair of baffles are fixed on the upper side of the collection box, and a spray pipe is fixed on the lower side of the baffles by clamps to prevent dust from being generated. The discharge port is located directly above the collection box, which facilitates the collection of aggregates.

[0006] As a further embodiment of this utility model: the collection box is placed above the base, which allows the top of the collection box to fit with the bottom of the screen box, thereby facilitating material feeding.

[0007] As a further embodiment of this utility model: a guide plate is fixed at one opening on the side of the screen box, and a guide plate is fixed at the other opening on the side of the screen box, so as to facilitate the discharge of the screened aggregate.

[0008] As a further embodiment of this utility model: a vibrating motor is fixed on one side of the screen box for screening aggregates.

[0009] As a further embodiment of this utility model: the spray pipe is connected to an external water supply pipe to facilitate the supply of water to the spray pipe for spraying.

A guide plate 17 is fixed on the side of the screen box 1 at the opening 1.2 to facilitate the discharge of the screened aggregate; a connecting seat is fixed on the outside of the screen box 1, a support rod 12 is fixed at the bottom of the connecting seat, an elastic rubber pad 13 is fixed at the bottom of the support rod 12, a support column 14 is fixed at the bottom of the elastic rubber pad 13, a base 15 is fixed at the bottom of the support column 14, and the support rod 12 passes through the elastic rubber pad 13 and is limited in the support column 14. A vibrating motor is fixed on one side of the screen box 1 for screening the aggregate. Combined with appendix Figure 1 , 2 It can be seen that the material guiding mechanism includes a cover 4. The top of the cover 4 is connected to a connecting pipe 6 through a corrugated pipe 5. A pair of hooks 7 are fixed at one end of the connecting pipe 6. The hooks 7 are hung on the side of the outer conveyor belt. The inner side of the cover 4 is obliquely fixed above the guide plate 3 to prevent the aggregate from falling directly onto the guide plate 3. Combined with appendix Figure 3 ,4 It can be seen that a pair of baffles 10 are fixed on the upper side of the collection box 9, and a spray pipe 11 is fixed on the lower side of the baffles 10 by a clamp.
