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

Example Embodiment

[0036] Example 1:

[0037] Such as Figure 1 - Figure 8 As shown, a dry sorting system suitable for sorting at the end coal, comprising a sorting bed 1, a base 3 having a sorting bed 1, a base 3 hinges having a number of articulated rods 2, the present embodiment In the hinge 2, four hinge rods 2 are provided, and the four hinge rods 2 are respectively disposed at four edge angles of the base 3, and the hinge 2 is distinguished from one end of the base 3 and the hinges of the sorting bed 1, and the base 3 is fixedly supported. The seat 4, the drive motor 5 is fixed, and the drive cam 6 is fixed to the shaft of the drive motor 5, and the drive cam 6 is provided below the sorting bed 1, and the outer wall of the cam 6 is driven and the selected bed 1 The lower side abuts.

[0038]The drive motor 5 drives the drive cam 6 to rotate. Since the driving cam 6 supports the sorting bed 1, the rotation of the drive cam 6 can drive the entire shock of the hidden binder 1, and the vibration ef...

Example Embodiment

[0046] Example 2:

[0047] Such as Figure 9 As shown, the difference from the embodiment is different from the arrangement of the support seat 4, and four support seats 4 are provided, and the four support seats 4 are disposed at four edge angles of the base 3, located in front of the front. The support seat 4 is rotated between the first driving shaft 25, and the second drive shaft 21 is rotated between the two support seats 4, and two of the first drive shaft 25 and the second drive shaft 21 are fixed. A drive cam 6, four drive cams 6, respectively, at four edge angles selected by the bed 1, drive the motor 5 to rotate the first driving shaft 25, and the first drive shaft 25 is fixedly secured to have an active sprocket 24, and the second A connection chain 23 is attached to the drive shaft 21, and the active sprocket 24 and the driven sprocket 22 are connected between the drive shaft 21.

[0048] The drive motor 5 causes the first driving shaft 25 to rotate, the rotation of the...

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...
