Description

Technical Field

[0001] The present invention relates to the technical field of coal separation equipment, and specifically relates to a digital coal sorting device based on the Internet of Things. Background Art

[0002] Intelligent dry separation of coal is an advanced lump coal gangue rejection process adopted in the domestic and foreign coal preparation fields in recent years. The intelligent dry separator uses X-ray detection and recognition technology to effectively separate coal and gangue through an intelligent control system. The intelligent dry separator for coal is an intelligent sorting device based on the Internet of Things. During operation, first, through high-frequency vibration, particles and powders are separated, and the powders are collected. Then, through big data processing, multi-dimensional technical analysis is carried out on the particles to obtain particle information. Then, coal gangue and coal are accurately sorted through air flow. However, when the raw materials are vibrating at high frequency inside the vibrating screen, although fine fragments in the raw materials can be separated, a large number of granular raw materials will directly roll onto the conveyor belt of the dry separator, causing the particles to overlap, and the X-ray detection cannot accurately identify them, thus affecting the sorting accuracy.

[0003] For example, in the screening equipment of the patent No. CN109499852A, specifically named "a vibrating screening device for an intelligent coal dry separator", after the raw materials are poured onto the vibrating screen and filtered by the vibrating screen, the granular raw materials will directly roll onto the conveyor belt of the dry separator, causing the particles to overlap and affecting the sorting.

A sealing block is slidably and sealingly connected inside the sealing groove. A sealing plate is slidably and sealingly connected inside the sealing groove.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3 , the present invention provides a technical solution: a digital coal sorting device based on the Internet of Things, including the main body 1 of the sorting machine, a vibrating screen 2 is movably installed on the surface of the main body 1 of the sorting machine, a feeding box 3 is fixedly connected to the bottom of the vibrating screen 2, a discharge pipe 4 is fixedly installed at the bottom of the feeding box 3, an aggregate box 5 is fixedly installed inside the main body 1 of the sorting machine, a first diversion plate 6 is fixedly connected inside the vibrating screen 2, a first filter screen 7 is fixedly installed inside the vibrating screen 2, a second diversion plate 8 is fixedly connected inside the vibrating screen 2, a second filter screen 9 is fixedly connected inside the vibrating screen 2, and the pore diameters on the surfaces of the first filter screen 7 and the second filter screen 9 are equal. By installing the first diversion plate 6, the first filter screen 7, the second diversion plate 8 and the second filter screen 9, the particles inside the vibrating screen 2 can be separated by size.

[0024] Please refer to Figures 2-5, a material leveling device 10 is fixedly installed at equal intervals inside the vibrating screen 2. The number of the material leveling devices 10 is two. The material leveling device 10 includes a fixed box 101 fixedly connected inside the vibrating screen 2. A motor 102 is fixedly installed inside the fixed box 101. The output end of the motor 102 is rotationally connected with a threaded rod 103 through a coupling. A sealing groove 104 is opened inside the fixed box 101. A sealing block 105 is hermetically slidably connected inside the sealing groove 104. Both the sealing groove 104 and the sealing block 105 are square. A threaded hole 1051 is opened at the center of the surface of the sealing block 105. The outer surface of the threaded rod 103 is threadedly rotated inside the threaded hole 1051. Limiting grooves 1052 are opened at equal intervals on the surface of the sealing block 105. Limiting rods are fixedly connected at equal intervals inside the sealing groove 104, and the surfaces of the limiting rods are slidably connected inside the limiting grooves 1052. A sealing plate 106 is hermetically slidably connected inside the sealing groove 104. A connecting block 107 is fixedly connected to the surface of the sealing plate 106. One end of the connecting block 107 extends to the outer surface of the fixed box 101. A resisting block 108 is fixedly connected to the surface of the connecting block 107. The resisting block 108 is a rubber block and is conical. By installing the material leveling device 10, the falling speed of the particles inside the vibrating screen 2 can be controlled, so that the particles can be laid flat in a single layer, which is convenient for X-ray detection and identification, enhances the sorting accuracy of coal and gangue, and enhances the practicability.

[0025] During operation, first adjust the resisting block 108 to a suitable height. When adjusting, start the motor 102. The motor 102 drives the threaded rod 103 to rotate, so that the sealing block 105 slides inside the sealing groove 104. By controlling the air pressure inside the sealing groove 104, the sealing plate 106 drives the connecting block 107 to slide up and down. After adjusting the position of the resisting block 108, put the raw material into the top inside the vibrating screen 2. Through the vibration of the vibrating screen 2, the powder material passes through the vibrating screen 2 and is collected inside the aggregate box 5 through the feeding box 3 and the discharge pipe 4. After the granular raw material inside the vibrating screen 2 is filtered by the first filter screen 7 and the second filter screen 9, the particles are classified. The classified particles roll down through two channels and are blocked by the material leveling device 10, so that the particles can fall at a uniform speed and in a uniform quantity. By installing the first diversion plate 6, the first filter screen 7, the second diversion plate 8 and the second filter screen 9, the particles inside the vibrating screen 2 can be separated by size, which can prevent the particles from getting stuck on the surface of the connecting block 107 when contacting the resisting block 108 due to too large a difference in particle size, and affecting the normal feeding due to material accumulation, thus enhancing the practicability.
