Problems solved by technology

[0004] There is no vibrating composite dry separation system suitable for fine coal separation in the existing dry separation devices. The reason is that the existing dry separation devices include feeding devices, sorting beds, discharge devices, supply Wind device, gas distributor and bottom bracket, and multi-layer bed sieves for screening are arranged on the sorting bed. When the existing dry separation device is used for sorting fine coal, the The sieve holes are relatively easy to block, which affects the screening of coal, and the cleaning of the sieve holes of the multi-layer bed sieve plate is inconvenient; in addition, the existing sorting bed is equipped with a vibrator, which drives the sorting bed to vibrate , but the sorting effect of this kind of vibration method for sorting fine coal is general

Embodiment 1

[0037] Such as Figure 1-Figure 8 As shown, a dry separation system suitable for separating fine coal includes a separation bed 1, a base 3 arranged below the separation bed 1, and a number of hinged rods 2 are hinged on the base 3. In this embodiment Among them, there are four hinged rods 2, and the four hinged rods 2 are respectively arranged at the four corners of the base 3. The end of the hinged rods 2 away from the base 3 is hinged to the sorting bed 1, and the base 3 is fixed with a support Seat 4, driving motor 5 is fixed on the supporting seat 4, driving cam 6 is fixed on the rotating shaft of driving motor 5, and driving cam 6 is arranged on the below of sorting bed body 1, and the outer wall of driving cam 6 is connected with the side of sorting bed body 1. The lower side abuts.

[0038]The driving motor 5 drives the driving cam 6 to rotate. Since the driving cam 6 supports the sorting bed 1, the rotation of the driving cam 6 can drive the overall vibration of the ...

Embodiment 2

[0047] Such as Figure 9 As shown, the difference between the present embodiment and the first embodiment is that the setting method of the support base 4 is different. There are four support bases 4, and the four support bases 4 are respectively arranged at the four corners of the base 3. A first drive shaft 25 is rotatably connected between the two support bases 4, a second drive shaft 21 is rotatably connected between the two support bases 4 at the back, and two are fixed on the first drive shaft 25 and the second drive shaft 21. One driving cam 6, four driving cams 6 are at the four corners of the sorting bed body 1 respectively, the driving motor 5 drives the first driving shaft 25 to rotate, the driving sprocket 24 is fixed on the first driving shaft 25, the second A driven sprocket 22 is fixed on the driving shaft 21 , and a connecting chain 23 is connected between the driving sprocket 24 and the driven sprocket 22 .

[0048] The driving motor 5 drives the first drive ...

Abstract

The dry separation system comprises a bed body, a driving device, a sieve plate and a feeding device, the driving device is a driving motor, sieve holes are distributed in the sieve plate, the sieve plate with the sieve holes is installed on the separation bed body, the feeding device conveys the slack coal to the separation bed body, and the slack coal is fed into the bed body. The sorting bed body is driven by the driving device to generate vibration and is used for sorting slack coal. According to the dry separation system suitable for separating slack coal, the problem that an existing separation mechanism blocks sieve holes is solved, and the separation capacity is improved; the ventilation device can ventilate air into the ventilation holes, then the air is blown into the screen holes from the communicating holes, and materials blocked in the screen holes can be blown away.

Description

technical field [0001] The invention belongs to the technical field of coal separation, and in particular relates to a dry separation system suitable for separation of fine coal. Background technique [0002] my country's coal preparation industry started relatively late, and its own coal preparation industry was established in the 1950s; during the "Eighth Five-Year Plan" period, the growth rate of raw coal selection exceeded the growth rate of raw coal for the first time, and during the "Ninth Five-Year Plan" and "Tenth Five-Year Plan" Continued rapid growth; in 2008, the amount of raw coal selected was 1.1 billion tons, and the selection rate was 43%; in 2009, my country produced a total of 3.05 billion tons of raw coal, and the raw coal washing rate basically did not increase; in recent years, my country has paid more and more attention to the development of coal preparation, especially The number of coal preparation plants has been increasing continuously from 2010 to now...
