Description

Technical Field

[0001] This utility model relates to the field of coal preparation technology, specifically a vertical coal dry separator conveying device. Background Technology

[0002] Coal gangue separators and dry coal separators are devices that automatically separate materials with different properties from other materials based on differences in material density, shape, material and other characteristics using X-ray photoelectric detection technology. They are also widely used in agricultural and industrial products. After screening out the coal, dry coal separators are usually equipped with conveyor belts to transport the screened coal.

[0003] Currently, after coal is screened out by a dry coal separator, the coal usually falls directly onto the conveyor belt, which can easily cause a large impact on the conveyor belt. After long-term use, this will damage the conveyor belt and affect its service life. To address this, we have proposed a vertical dry coal separator conveying device. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical coal dry separator conveying device to solve the problem in the existing technology that after the coal is screened out, it usually falls directly onto the conveyor belt, which can easily cause a large impact on the conveyor belt. After long-term use, this will damage the conveyor belt and affect its service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vertical coal dry separator conveying device, comprising a shell, a conveyor belt fixed to the inner wall of the shell, a discharge pipe uniformly fixed to the top of the shell, a buffer mechanism uniformly arranged on the inner wall of the shell, and a dust removal mechanism arranged on one side of the shell.

[0006] The buffer mechanism includes inclined plates uniformly fixed to the inner sidewall of the outer shell, a baffle plate rotating inside the inclined plate, a connecting seat symmetrically fixed to the bottom of the baffle plate, a connecting rod rotating inside the connecting seat, a sleeve symmetrically fixed to the bottom of the inclined plate, a buffer spring fixed to one side of the inner cavity of the sleeve, a connecting plate fixed to one end of the buffer spring, and a moving rod fixed to one side of the connecting plate.

[0007] Preferably, the buffer mechanism further includes a damper fixed to one side of the inner cavity of the sleeve, and the buffer spring is sleeved on the outside of the damper.

[0008] Preferably, one end of the damper is fixed to the middle of one side of the connecting plate to absorb the potential energy of the buffer spring and prevent the buffer spring from shaking violently, and the connecting plate slides on the inner wall of the sleeve.

[0009] Preferably, one end of the connecting rod rotates inside the movable rod, the movable rod passes through one side of the sleeve, and the movable rod is slidably connected to the sleeve, so that the movable rod can be easily moved when the connecting rod deflects.

[0010] Preferably, the dust removal mechanism includes a dust removal pipe connected to the middle of one side of the outer casing, a slot extending through the middle of the top of the dust removal pipe, a negative pressure fan fixed through the middle of one side of the dust removal pipe, an mounting plate fixed to the inner wall of the dust removal pipe, a rotating shaft extending through the middle of one side of the mounting plate, a rotating fan fixed to one end of the rotating shaft, a fixing plate fixed to the other end of the rotating shaft, a cleaning brush fixed to one side of the fixing plate, and a filter screen connected inside the slot.

[0011] Preferably, a sealing gasket is adhered to the outer wall of the filter screen to ensure airtightness, and the filter screen is connected to the dust removal pipe by bolts to facilitate disassembly of the filter screen. One side of the cleaning brush is attached to one side of the filter screen.

[0012] Preferably, the air intake of the negative pressure fan is located inside the dust removal pipe, and the dust removal pipe is connected to the outer casing by bolts, which facilitates the disassembly of the dust removal pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes a buffer mechanism. When coal is discharged from the discharge pipe, it first falls onto an inclined plate, where it is initially buffered. Then, the coal slides off the inclined plate and impacts a baffle, causing the baffle to deflect. This deflects the connecting seat, which in turn deflects the connecting rod, causing the moving rod to move. This causes the connecting plate to compress the buffer spring and damper. Through the cooperation of the buffer spring and damper, the impact is buffered. The baffle further buffers the impact of the falling coal, reducing the impact force of the coal falling onto the conveyor belt. This provides sufficient buffering, reduces damage to the conveyor belt, and extends its service life.

[0015] 2. In this application, the dust removal mechanism utilizes a negative pressure fan to generate negative pressure, causing airflow and drawing dust from inside the casing into the dust removal pipe. The dust is then filtered through a filter screen, preventing it from dispersing into the air and ensuring a clean environment. Simultaneously, the airflow impacts the rotating fan, causing it to rotate and drive the shaft to rotate. This causes the fixed plate to move the cleaning brush, cleaning the filter screen and preventing it from clogging and affecting the filtration effect. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5 As shown, this utility model provides a technical solution for a vertical coal dry separator conveying device, including a shell 100, a conveyor belt 200 fixed on the inner side wall of the shell 100, a discharge pipe 300 evenly fixed on the top of the shell 100, a buffer mechanism 400 evenly arranged on the inner side wall of the shell 100, and a dust removal mechanism 500 arranged on one side of the shell 100.

[0024] Please see Figure 2 and Figure 3The buffer mechanism 400 includes inclined plates 410 uniformly fixed to the inner wall of the outer casing 100. A baffle 420 rotatably rotates inside the inclined plate 410. A connecting seat 430 is symmetrically fixed to the bottom of the baffle 420. A connecting rod 440 rotatably rotates inside the connecting seat 430. A sleeve 450 is symmetrically fixed to the bottom of the inclined plate 410. A buffer spring 460 is fixed to one side of the inner cavity of the sleeve 450. A connecting plate 470 is fixed to one end of the buffer spring 460. A moving rod 480 is fixed to one side of the connecting plate 470. The buffer mechanism 400 also includes a damper 461 fixed to one side of the inner cavity of the sleeve 450. The buffer spring 460 is sleeved on the outside of the damper 461. One end of the damper 461 is fixed to the middle of one side of the connecting plate 470, and the connecting plate 470 slides against the inner wall of the sleeve 450. One end of the connecting rod 440 rotatably rotates inside the moving rod 480. 480 passes through one side of the sleeve 450, and the moving rod 480 is slidably connected to the sleeve 450. Utilizing the buffer mechanism 400, when coal is discharged from the discharge pipe 300, it first falls onto the inclined plate 410, where it is initially buffered. Then, the coal slides off the inclined plate 410, impacting the baffle 420, causing the baffle 420 to deflect. This deflects the connecting seat 430, causing the connecting rod 440 to deflect, which in turn moves the moving rod 480. The connecting plate 470 then compresses the buffer spring 460 and the damper 461. Through the cooperation of the buffer spring 460 and the damper 461, the impact is buffered. The baffle 420 further buffers the impact of the falling coal, reducing the impact force of the coal falling onto the conveyor belt 200, effectively buffering the impact, minimizing damage to the conveyor belt 200, and extending its service life.

[0025] Please see Figure 4 and Figure 5The dust removal mechanism 500 includes a dust removal pipe 510 connected to the middle of one side of the outer casing 100. A slot 511 is provided through the middle of the top of the dust removal pipe 510. A negative pressure fan 520 is fixed through the middle of one side of the dust removal pipe 510. A mounting plate 530 is fixed to the inner wall of the dust removal pipe 510. A rotating shaft 540 is rotatably driven through the middle of one side of the mounting plate 530. A rotating fan 550 is fixed to one end of the rotating shaft 540, and a fixing plate 560 is fixed to the other end. A cleaning brush 570 is fixed to one side of the fixing plate 560. A filter screen 580 is connected inside the slot 511. A sealing gasket is adhered to the outer wall of the filter screen 580. The filter screen 580 is connected to the dust removal pipe 510 by bolts. The cleaning brush 570... One side is attached to the side of the filter screen 580; the air intake of the negative pressure fan 520 is located inside the dust removal pipe 510, and the dust removal pipe 510 is connected to the outer casing 100 by bolts; by using the dust removal mechanism 500, the negative pressure generated by starting the negative pressure fan 520 causes air to flow, drawing dust from inside the outer casing 100 into the dust removal pipe 510, where it is filtered by the filter screen 580, thus preventing dust from dispersing into the air and ensuring a clean environment. At the same time, the air flow impacts the rotating fan 550, causing it to rotate, which in turn drives the rotating shaft 540 to rotate, causing the fixed plate 560 to move the cleaning brush 570 to clean the filter screen 580, preventing the filter screen 580 from clogging during filtration and thus preventing the filtration effect from being affected.

[0026] In use, after coal preparation is completed, the negative pressure fan 520 is started, and the coal is discharged from the discharge pipe 300. It first falls onto the inclined plate 410, where it is initially buffered. Then, the coal slides off the inclined plate 410, impacting the baffle 420, causing it to deflect. This deflects the connecting seat 430, which in turn deflects the connecting rod 440, thereby moving the moving rod 480. The connecting plate 470 then compresses the buffer spring 460 and the damper 461. Through the cooperation of the buffer spring 460 and the damper 461, the impact is buffered, thus utilizing the baffle 420 to cushion the coal. The impact of the falling coal is buffered again, reducing the impact force of the coal falling onto the conveyor belt 200. The coal then falls onto the conveyor belt 200 for conveying. At the same time, the negative pressure fan 520 is activated to generate negative pressure, causing airflow and drawing dust from inside the outer casing 100 into the dust collection pipe 510. The dust is then filtered by the filter screen 580, thus preventing the dust from dispersing into the air. As the airflow occurs, it impacts the rotating fan 550, causing it to rotate. This, in turn, drives the rotating shaft 540 to rotate, causing the fixed plate 560 to move the cleaning brush 570 to clean the filter screen 580, preventing the filter screen 580 from clogging during filtration.
