Description

Technical Field

[0001] This utility model relates to the field of coal screening technology, and in particular to a high-efficiency separation and screening device for coal production. Background Technology

[0002] In the coal production sector, high-efficiency separation and screening equipment is extremely crucial. Coal, as an important basic energy source in my country, accounts for a high proportion of the primary energy production and consumption structure and plays an important supporting role in rapid economic development. With social progress, various industries have increasingly stringent requirements for coal quality. High-efficiency separation and screening equipment can accurately remove impurities from coal, improve coal quality, and meet the needs of different industries.

[0003] In the early days, coal screening relied mainly on manual picking and simple screening tools. Workers manually picked out gangue and impurities from the coal with their eyes and experience, using only simple sieves. This method was extremely inefficient, had limited processing capacity, and the screening accuracy depended entirely on the worker's skill level and working condition, making it difficult to guarantee the stability of coal quality. With the gradual development of technology, mechanical screening equipment emerged, which used mechanical vibration to screen and classify coal. However, these traditional devices were unable to accurately classify the particle size and separate impurities from the coal, resulting in inconsistent coal quality after screening, which could not meet the high requirements of modern industry for coal quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency separation and screening device for coal production, aiming to improve the problem that traditional equipment in the prior art is unable to accurately classify coal by particle size and separate impurities, resulting in inconsistent coal quality after screening and failing to meet the high requirements of modern industry for coal quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency separation and screening device for coal production, comprising a bottom plate, a vibration mechanism provided on the top of the bottom plate for screening coal, and a cleaning mechanism provided at the bottom of the vibration mechanism for cleaning.

[0006] The vibration mechanism includes a column fixed to the top edge of the base plate. A support assembly is provided on the outer wall of the column. A screen is provided between two adjacent support assemblies. A limit assembly is provided in the middle of both sides of the screen. A rotating assembly is provided on the inner wall of the screen. A second motor is fixedly connected to the top of the base plate. A conversion assembly is provided at the output end of the second motor. A vibration assembly is provided on the top of the conversion assembly. A transmission assembly is provided on the outer wall of the screen.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes a second fixed plate, which is fixed to the bottom of the screen. A third motor is fixedly connected to the outer wall of the second fixed plate. A threaded rod is fixedly connected to the output end of the third motor. A threaded sleeve is threadedly connected to the outer wall of the threaded rod. A gear is rotatably connected to the outer wall of the threaded sleeve. A rack is provided at the bottom of the gear. A rotating brush is fixedly connected to the outer wall of the gear.

[0009] As a further description of the above technical solution:

[0010] The support assembly includes a secondary crossbar, which is fixed to the middle of the column, and a primary crossbar is fixedly connected to the top of the column.

[0011] As a further description of the above technical solution:

[0012] The limiting component includes a fixing post, which is fixed in the middle of the screen, and multiple limiting posts are fixedly connected to the outer wall of the screen.

[0013] As a further description of the above technical solution:

[0014] The rotating assembly includes a motor, which is fixed to the outer wall of the screen. The output end of the motor is fixedly connected to a rotating shaft, and multiple soft brushes are fixedly connected to the outer wall of the rotating shaft.

[0015] As a further description of the above technical solution:

[0016] The transmission assembly includes pulleys, which are fixed to one end of a rotating shaft, and a transmission belt is used to drive the two adjacent pulleys together.

[0017] As a further description of the above technical solution:

[0018] The conversion component includes an eccentric column, which is fixed to the output end of the second motor, and a limit block is slidably connected to the outer wall of the eccentric column.

[0020] The vibration assembly includes a sliding rod, which is fixed to the top of the limiting block. A limiting sleeve is slidably connected to the middle of the sliding rod, and multiple fixing plates are fixedly connected to the outer wall of the sliding rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the coal to be separated is conveyed into the top screen, and motor two starts. This drives the conversion component to rotate, causing the limiting block and sliding rod to slide up and down. The fixing plate fixed to the outer wall of the sliding rod pushes the screen to rotate around the fixed pile. The rapid pushing causes the screen to shake, allowing coal particles smaller than the upper aperture to fall through, while coal particles larger than the upper aperture slide down along the inclined angle of the screen. The two screens are inclined in opposite directions, allowing coal of different specifications to be conveyed in different directions, thus achieving coal classification by particle size. Motor one drives the rotating shaft and soft brush to rotate, causing the coal to tumble inside the screen, extending the screening time.

[0023] 2. In this utility model, when the mesh at the bottom of the screen is blocked, the motor three is started. The motor three drives the threaded rod to rotate. The inner wall of the gear is threadedly connected to the outer wall of the threaded rod, so that the gear moves along the axis of the threaded rod, driving the rotating brush and the gear to move. The gear meshes with the rack, that is, when the rotating brush moves, it rotates to unclog the screen at the bottom of the screen, which facilitates the long-term use of the equipment.

[0038] Specifically, the support assembly 202 consists of a secondary crossbar 2021, which is securely installed at the center of the column 201 to ensure the stability of the entire structure. At the top of the column 201, a primary crossbar 2022 is firmly connected, providing additional support to the entire structure. Furthermore, the limiting assembly 204 consists of a fixing post 2041, which is fixed at the center of the screen 203 to ensure stability and safety. The outer wall of the screen 203... On the upper part, multiple limit posts 2042 are fixed, which provide additional limit protection for the entire structure. The rotating assembly 205 consists of a motor 2051, which is fixed on the outer wall of the screen 203 and provides power to the entire structure. At the output end of the motor 2051, the rotating shaft 2052 is firmly connected, which is responsible for transmitting the power of the motor to the entire structure. On the outer wall of the rotating shaft 2052, multiple soft brushes 2053 are fixed, which are responsible for cleaning and maintaining the entire structure.

[0039] Please see the appendix Figure 3 - Appendix Figure 5 The transmission assembly 206 includes a pulley 2061, which is fixed to one end of the rotating shaft 2052. A transmission belt 2062 is connected between adjacent pulleys 2061. The conversion assembly 208 includes an eccentric column 2081, which is fixed to the output end of the motor 207. A limit block 2082 is slidably connected to the outer wall of the eccentric column 2081. The vibration assembly 209 includes a sliding rod 2091, which is fixed to the top of the limit block 2082. A limit sleeve 2093 is slidably connected to the middle of the sliding rod 2091. Multiple fixing plates 2092 are fixedly connected to the outer wall of the sliding rod 2091.

[0040] Specifically, the transmission assembly 206 includes multiple pulleys 2061, each of which is securely fixed to one end of the rotating shaft 2052 to ensure stable operation. A transmission belt 2062 connects adjacent positions of these pulleys 2061 to achieve efficient power transmission. The conversion assembly 208 mainly consists of an eccentric column 2081, which is fixedly installed at the output end of the second motor 207 to ensure it can generate corresponding eccentric movement as the second motor 207 operates. The outer wall of the eccentric column 2081 is provided with a sliding connection structure, which connects to the limiting block 2082. A sliding connection is used to limit its range of motion and maintain the stability of the motion. The vibration assembly 209 includes a sliding rod 2091. One end of the sliding rod 2091 is fixed to the top of the limiting block 2082 to ensure that it can move synchronously with the movement of the limiting block 2082.

These fixing plates 2092 are evenly distributed to enhance the structural stability and functionality of the entire vibration assembly 209.

[0041] Working principle: The coal to be separated is fed into the top screen 203, and the second motor 207 starts. This drives the conversion component 208 to rotate, causing the limiting block 2082 and the sliding rod 2091 to slide up and down. The fixing plate 2092 fixed to the outer wall of the sliding rod 2091 pushes the screen 203 to rotate around the fixing pile 2041. The rapid pushing causes the screen 203 to shake, allowing coal particles smaller than the upper aperture to fall through, while coal particles larger than the upper aperture slide down the inclined angle of the screen 203. The two layers of screens 203 are inclined in opposite directions, allowing coal of different specifications to be conveyed in different directions, thus achieving coal classification by particle size. The first motor 2051 drives the rotating shaft 2052 and the soft brush 2053 to rotate, causing the coal to tumble inside the screen 203, extending the screening time.

[0042] When the mesh at the bottom of the screen 203 becomes clogged, the motor 302 is started. The motor 302 drives the threaded rod 303 to rotate. The inner wall of the gear 305 is threadedly connected to the outer wall of the threaded rod 303, causing the gear 305 to move along the axis of the threaded rod 303. This moves the rotating brush 307 and the gear 305. The gear 305 meshes with the rack 306, so that the rotating brush 307 rotates when it moves, clearing the bottom of the screen 203 and facilitating the long-term use of the equipment.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
