Description
Technical Field
[0001] The invention relates to the technical field of conveyor belts for coal mines, in particular to a conveyor belt for coal mines with a dust reduction function. Background Art
[0002] In the process of coal mining and transportation, conveyor belts, as key equipment, undertake the important task of material transportation. However, the importance of dust reduction function is often ignored in the design of traditional conveyor belts for coal mines, which leads to a series of problems in practical applications.
[0003] First, the working environment of coal mines is usually full of dust, which not only poses a serious threat to the health of workers, but long-term inhalation may also lead to occupational diseases such as pneumoconiosis. Traditional conveyor belts cannot effectively suppress the flying of dust when transporting materials, which deteriorates the air quality in the working area and increases the health risks of workers. Secondly, the accumulation of dust will also cause damage to the conveyor belt itself and its surrounding equipment. Dust adheres to the surface of the conveyor belt and the driving components, which will accelerate wear and shorten the service life of the equipment. At the same time, dust may also clog the gaps and holes in the conveyor belt, affecting the normal transportation of materials. In addition, the dust problem also has an impact on the environment that cannot be ignored. The dust generated during coal mining and transportation, if directly discharged into the atmosphere without effective treatment, will pollute the surrounding environment and destroy the ecological balance.

[0010] Preferably, a miscellaneous collecting box is fixedly installed at the bottom of the support plate, and a discharge pipe is connected to the center of the bottom of the miscellaneous collecting box. The bottom of the discharge pipe passes through the support plate and the miscellaneous collecting box in sequence and extends to the interior of the miscellaneous collecting box.

[0013] A method for using a conveyor belt with dust reduction function for a coal mine comprises the following steps:
[0014] Step one: first, both base frames are rotatably connected with driven wheels, and the two driven wheels are connected through the conveyor belt body to form a closed-loop conveying structure. The frequency conversion motor is fixedly installed on the top of the rear end of one base frame, and its output end is fixedly connected to the rear end of the driven wheel on one side. Through the drive of the frequency conversion motor, the running speed of the conveyor belt body can be adjusted to meet different work requirements.
[0015] Step 2: The water tank is filled with water, which can be replenished regularly through the water supply pipe. The water pump in the water tank draws out the water and transports it to the water collecting bucket through the drain pipe. The spray head 1 at the bottom of the water collecting bucket sprays water onto the conveyor belt body and the material above it to initially wet the material and reduce dust. At the same time, the spray head 2 in the trapezoidal frame receives water through the external mounting pipe to further spray the material to enhance the dust reduction effect. The design of the funnel-shaped plate enables the water flow to be evenly distributed in the trapezoidal frame. The funnel-shaped plate is stably installed on the trapezoidal frame by clamping the clamping slide and the clamping groove and fixing with the fixing bolts.
[0016] Step 3: The impurities and dust accumulated on the coarse filter will gradually increase with the continuous operation of the conveyor belt and the continuous operation of the dust reduction system. When cleaning is needed, the discharge pipe at the bottom of the receiving box can be opened to allow the impurities to fall into the collecting box. The fine filter in the collecting box further filters the impurities to ensure that only fine particles pass through, avoiding troubles in subsequent processing. Finally, the impurities are discharged from the device through the outlet pipe.
[0017] Step 4: The fan inside the chassis inhales air through the air inlet pipe and blows the air to the material on the conveyor belt body through the air outlet pipe. This airflow helps to disperse the fine dust suspended in the air and accelerate its sedimentation, thereby improving the dust reduction effect. The design of the movable rod allows the fan and chassis to adjust their angles and positions according to actual needs to adapt to different dust reduction requirements.
[0018] Step five, the snap-in slide plate at the bottom of the funnel-shaped plate cooperates with the snap-in slide groove at the top of the trapezoidal frame and is fastened by fixing bolts. This design ensures the close connection and sealing between the funnel-shaped plate and the trapezoidal frame, preventing moisture and impurities from leaking during the dust reduction process. The setting of the sealing gasket further enhances the sealing effect and ensures the stability and efficiency of the dust reduction structure.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] The conveyor belt with dust reduction function for coal mines realizes continuous spraying of the conveyor belt body and the material above it through the combined action of a water tank, a water pump, a water collection bucket, and spray heads one and two, effectively wetting the material and reducing dust flying. This mechanism significantly reduces the dust concentration in the working area, thereby improving the air quality and reducing the risk of workers suffering from occupational diseases due to long-term inhalation of dust. The cooperation between the funnel-shaped plate and the trapezoidal frame through the clamping slide plate and the clamping slide groove, as well as the tightening of the fixing bolts, ensures that moisture and impurities will not leak during the dust reduction process, further enhancing the dust reduction effect and ensuring the cleanliness of the working environment. The dual filtering design of the coarse filter and the fine filter effectively intercepts impurities and dust generated during the dust reduction process, and avoids dust on the surface and The accumulation on the driving components reduces the wear and blockage problems caused by dust, thereby extending the service life of the conveyor belt and its peripheral equipment. By opening the discharge pipe at the bottom of the receiving box, the accumulated impurities and dust can be easily cleaned, which simplifies the maintenance process and reduces the maintenance cost. The present invention significantly reduces the emission of dust during coal mining and transportation through an efficient dust reduction mechanism, reduces pollution to the surrounding environment, and protects the ecological balance. Through the drive of the variable frequency motor, the running speed of the conveyor belt body can be adjusted to meet different work requirements, thereby improving the adaptability and flexibility of the equipment. The design of the movable rod allows the fan and the chassis to adjust the angle and position according to actual needs to adapt to different dust reduction requirements, further enhancing the practicability and dust reduction effect of the equipment.

Finally, the impurities are discharged from the device through the impurity discharge pipe; Step 4: The fan (17) inside the chassis (16) inhales air through the air inlet pipe (19) and blows the air toward the material on the conveyor belt body (3) through the air outlet pipe (18). This airflow helps to disperse the fine dust suspended in the air and accelerate its sedimentation, thereby improving the dust reduction effect. The design of the movable rod (15) allows the fan (17) and the chassis (16) to adjust their angles and positions according to actual needs to adapt to different dust reduction requirements; Step 5: The snap-fitting slide plate (27) at the bottom of the funnel-shaped plate (26) cooperates with the snap-fitting groove (25) at the top of the trapezoidal frame (24) and is fastened by fixing bolts (29). This design ensures a tight connection and sealing between the funnel-shaped plate (26) and the trapezoidal frame (24), preventing moisture and impurities from leaking during the dust reduction process. The provision of the sealing gasket (28) further enhances the sealing effect, thereby ensuring the stability and efficiency of the dust reduction structure.
