Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal powder separation technology, specifically to a coal crusher separator. Background Technology
[0002] In the coal processing industry, traditional coal crusher separators mostly use fixed screens or vibrating screens to separate coal lumps from coal powder. These devices use gravity or mechanical vibration to force coal lumps and coal powder through the screen openings to achieve particle size classification, and their core relies on the fixed design of the screen opening diameter.
[0003] However, this technology has significant drawbacks: First, fixed screen openings are prone to clogging due to factors such as coal moisture content and uneven particle size, leading to decreased separation efficiency and the need for frequent shutdowns for cleaning. Second, large, uncrushed coal pieces separated from the screen must be manually collected and fed back into the coal crusher, which is cumbersome and inefficient. Third, equipment such as vibrating screens relies on mechanical vibration drives, resulting in high energy consumption and complex transmission structures, leading to high maintenance costs. Fourth, the open screening process easily causes coal ash to scatter, polluting the working environment and accelerating equipment wear. These problems severely restrict the continuity and economy of coal processing. Utility Model Content
[0004] The present invention aims to provide a coal crusher separator to solve the problem of incomplete coal crushing.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a coal crusher separator, including a pipe body, a feed inlet, a discharge pipe, and a separation component. The feed inlet is connected to the top end of the pipe body, and the discharge pipe is connected to the bottom end of the pipe body. The separation component includes a motor, a feeding block, a separation pipe, and a screen. The separation pipe that receives coal blocks and transports them back to the coal crusher is connected to one end of the pipe body, the motor is connected to the other end of the pipe body, the output shaft of the motor passes through the pipe body and is connected to the feeding block, and the screen is connected to the inner wall of the pipe body.
[0006] The working principle of this utility model is as follows: The coal mixture crushed by the fine coal crusher falls into the feed inlet, the motor starts, and the output shaft of the motor drives the separation component to rotate. After being transported and separated by the separation component, the standard coal blocks fall through the screen into the discharge pipe and are transported out of the discharge pipe. Larger coal blocks continue to be transported with the separation component. After being transported to the separation pipe, the coal blocks are transported back to the coal crusher.
[0007] The beneficial effects of this utility model are as follows: standard coal blocks and incompletely crushed coal blocks are separated by a method of simultaneous transportation and separation. The separated coal blocks can be returned to the crusher by a blower, while the standard coal blocks are transported through another channel. The coal blocks can be transported continuously without interruption, which avoids the coal blocks from clogging in the separation device.
[0008] Furthermore, the feeding block includes a rotating rod and helical blades. The rotating rod is connected to the output shaft of the motor, and the helical blades are horizontally arranged around the rotating rod. During operation, the output shaft of the motor drives the rotating rod to rotate, and the helical blades on the rotating rod also rotate, causing the coal mixture to be continuously transported forward.
[0009] Furthermore, the separating pipe includes an inclined pipe and a vertical pipe. One end of the inclined pipe is connected to the pipe body, and the other end of the inclined pipe is connected to the vertical pipe. The bottom of the vertical pipe has a cavity, and a blower is installed in the cavity. During operation, the inclined pipe transports the coal block to the bottom of the vertical pipe, and the blower starts to operate, blowing the coal block into the coal mill.
[0010] Furthermore, a filter screen is installed at the top of the cavity, with gaps smaller than those of the coal lumps. This filter screen prevents coal lumps from falling into the blower.
[0011] Furthermore, the discharge pipe is funnel-shaped. This funnel-shaped discharge pipe allows the coal blocks to be concentrated and buffered before being transported out, preventing the direct discharge of coal ash and the resulting impact.
[0012] Furthermore, the feed inlet is located at the end of the pipe body closer to the motor. This feed inlet positioning allows the coal mixture to be screened for the longest possible time. Attached Figure Description

[0018] The basic implementation examples are as follows: Figure 1 -Appendix Figure 3As shown: A coal crusher separator includes a pipe body 3, a feed inlet 2, a discharge pipe 602, and a separation component 6. The feed inlet 2 is connected to the top left side of the pipe body 3, and the discharge pipe 602 is connected to the bottom middle of the pipe body 3. The discharge pipe 602 is funnel-shaped. The separation component 6 includes a motor 1, a rotating rod 604, an inclined pipe 4, a vertical pipe 5, and a screen 601. The motor 1 is fixedly connected to the left end of the pipe body 3. The output shaft of the motor 1 passes through the pipe body 3 and is fixedly connected to the rotating rod 604. The rotating rod 604 is horizontally rotatably connected inside the pipe body 3. A spiral blade 603 is fixedly connected to 604, which rotates from left to right. An inclined tube 4 is connected to the right end of the tube body 3. The other end of the inclined tube 4 is inclined downward and connected to the bottom end of the side wall of the vertical tube 5. A cavity 502 is provided at the bottom of the vertical tube 5. A filter screen 501 is fixedly connected to the top of the cavity 502. The gap of the filter screen 501 is smaller than that of the coal block. A blower 503 is fixedly connected inside the cavity 502. The blower 503 is located directly below the filter screen 501. A screen 601 is fixedly connected to the inner wall of the tube body 3. A gap is left between the screen 601 and the tube body 3.
[0019] The specific implementation process is as follows: The coal mixture crushed by the fine coal crusher falls into the feed inlet 2. The motor 1 starts, and the output shaft of the motor 1 drives the rotating rod 604 to rotate. The spiral blades 603 on the rotating rod 604 also rotate. The spiral blades 603 drive the coal mixture to be transported forward continuously. During the transportation process, the standard coal blocks fall from the screen 601 into the discharge pipe 602. The standard coal blocks are transported out from the discharge pipe 602. The large coal blocks continue to be transported with the spiral blades 603. After the coal blocks reach the rightmost end of the pipe body 3, they are transported through the inclined pipe 4 to the inner bottom of the vertical pipe 5. The blower 503 starts to operate and blows the coal blocks into the crusher.
