Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal structure of a mine tailing dry separator. Background Art

[0002] A tailings dry sorter is a device used to screen and separate ore. It separates different materials from ore according to particle size by vibrating the screen surface. Therefore, a tailings dry sorter usually generates a large amount of dust. During use, the dust will have an impact on the environment and the health of the workers, and will also reduce the operating efficiency and life of the equipment. Therefore, a tailings dry sorter is usually equipped with a dust removal structure to collect and treat the generated dust and waste. The dust removal structure can effectively collect and treat the dust generated by the tailings dry sorter, improve the air quality in the workplace, reduce the impact of dust on the health of workers, and improve the comfort and safety of the working environment. The dust removal structure can also reduce the erosion and damage of dust to the equipment, extend the service life of the tailings dry sorter, and reduce the maintenance cost and repair frequency of the equipment.

[0003] For this purpose, the utility model patent with publication number CN220779492U discloses a dust removal device for an iron ore dry sorting machine, which relates to the technical field of dust removal devices, including a dust removal component and a dust collection component, the bottom of the dust removal component is fixedly plugged with the top of the dust collection component, the dust removal component includes a dust removal pipe, the bottom of the dust removal pipe is fixedly plugged with the top of the dust collection component, a motor is fixedly installed on the top of the dust removal pipe, the tail end of the dust removal pipe is fixedly connected to an iron net, the inner wall of the dust removal pipe is fixedly installed with a dust filter net, and the inner wall of the dust removal pipe is rotatably connected with a screw rod. The utility model installs the dust removal pipe on the fan, and then when the fan rotates to extract air, the dust removal pipe is used to absorb the air containing a large amount of dust when the iron ore dry sorting machine is in operation, and after the dust-containing air enters the dust removal pipe and is filtered and adsorbed by the dust filter net, the clean air is discharged from the tail end of the dust removal pipe, so as to reduce the dust generated when the iron ore dry sorting machine is in operation.

[0004] However, the dust filter mesh of the patent is easily clogged after long-term use, and simple scraping and sweeping cannot effectively dredge the clogged mesh. Summary of the invention

[0005] The utility model aims to provide a dust removal structure for a mine tailing dry sorting machine in view of the above-mentioned deficiencies in the prior art, which is convenient to open and replace the internal equipment and can effectively avoid the use being affected by aging.

[0013] The utility model is simple and convenient to use. It only needs to fix the ventilation duct and the fan in the exhaust port of the tailings dry sorting machine through the flange, and then pull out the second fixing block and hold the handle to rotate. The rotation of the handle drives the cylinder to rotate, and then drives the guide plate to rotate, so as to control the air outlet speed. The airflow containing a large amount of dust will be blocked by the baffle when flowing in the ventilation duct, thereby increasing the time that the airflow stays in the ventilation duct, so that it is convenient for the dust removal bag to intercept the dust in the airflow, and the airflow discharged from the air outlet will fly to the ground to avoid affecting the passing users.

The observation window can facilitate the user to observe the use of the dust removal bag and facilitate timely replacement. The baffle in the ventilation duct can effectively increase the residence time of the airflow in the ventilation duct, increase the dust removal effect, and can also change the exhaust flow velocity of the air outlet, further increasing the residence time of the airflow in the ventilation duct.

DETAILED DESCRIPTION

[0021] Figure 1 , Figure 2 and Figure 3The utility model schematically shows a dust removal structure of a mine tailing dry sorting machine, comprising a ventilation duct 1, an air inlet 12 is provided at one end of the ventilation duct 1, and an air outlet 13 is provided at the other end, the air outlet 13 opens downward, a cylinder 14 is rotatably installed on the inner wall of the ventilation duct 1 close to the air outlet 13, a guide plate 15 is fixedly installed on the surface of the cylinder 14, one end of the cylinder 14 passes through the inner wall of the ventilation duct 1 and is fixedly connected to a first clamping block 16, one end of the first clamping block 16 is arranged in contact with the outer wall of the ventilation duct 1, a handle 17 is fixedly installed on the end of the first clamping block 16 away from the ventilation duct 1, a support platform 18 is contacted above the first clamping block 16, and one end of the support platform 18 is fixedly connected to the outer wall of the ventilation duct 1, A second clamping block 19 is slidably installed in the middle of the support platform 18, and the second clamping block 19 is in contact and connected with the first clamping block 16. A dust reduction device 2 which is easy to replace is provided in the middle of the ventilation duct 1, and an observation window 3 is provided in the ventilation duct 1 near the dust reduction device 2. The observation window 3 can be made of glass or transparent acrylic plate and other materials to facilitate observation of the situation in the ventilation duct 1. A flange 4 is fixedly installed in the ventilation duct 1 near the air inlet 12, and a plurality of baffles 5 which are integrally formed with the ventilation duct 1 are provided on the inner wall of the ventilation duct 1 near the dust reduction device 2. The plurality of baffles 5 are staggered up and down, and the baffles 5 can reduce the airflow velocity, thereby increasing the time that the airflow stays in the ventilation duct 1, thereby improving the dust reduction effect.

[0022] In actual use, it is only necessary to fix the air inlet 12 of the ventilation duct 1 with the ventilation pipe of the tailings dry sorting machine through the flange 4. At this time, the air flow will enter the ventilation duct 1 along the air inlet 12 and contact the baffle 5 and the dust bag 24 in the dust reduction device 2, so that the dust bag 24 absorbs the dust in the air flow and discharges it from the air outlet 13 after the dust reduction is completed. The air outlet 13 opens downward, which can effectively prevent the air flow from blowing to passers-by. To adjust the air outlet speed of the air outlet 13, you only need to pull out the second card block 19 and then hold the handle 17 and rotate it. The rotation of the handle 17 will drive the cylinder 14 to rotate, and the rotation of the cylinder 14 will drive the guide plate 15 to change its angle, thereby changing the size of the air outlet 13, thereby limiting the air outlet speed.

[0023] like Figure 4The dust reduction device 2 shown includes a mounting groove 21, in which a mounting plate 22 integrally formed with the mounting groove 21 is provided, and a plurality of through holes 23 are opened on the surface of the mounting plate 22, and dust bags 24 are installed in contact with the through holes 23. The dust bag 24 can adopt AKPE and other models, which are polyester dust bags with fine fiber diameter and large specific surface area, and can effectively capture tiny particles and dust. Moreover, this model has its own skeleton, which can effectively improve the strength and provide efficient filtering effect. A sealing plate 25 is provided in contact with the top of the dust bag 24, and the sealing plate 25 is in contact with the mounting groove 21. A pair of grip blocks 26 are fixedly installed on the top of the sealing plate 25. A lock 6 is provided in the sealing plate 25, and the lock 6 can adopt MS705-3 and other models. This model has a simple structure and is durable. A sealing strip is provided at the contact between the sealing plate 25 and the mounting groove 21. The sealing strip can be made of airtight materials such as rubber, which can effectively prevent gas leakage or rainwater from entering.

[0024] In practice, the lock 6 is first opened by a key, and then the sealing plate 25 can be opened by holding the grip 26 and lifting it upwards. At this time, the dust bag 24 to be replaced can be pulled out, and after the replacement is completed, the sealing plate 25 can be covered again for normal use.
