Description

Technical Field

[0001] The invention relates to the technical field of mineral material conveying, in particular to a quartz sand conveying device with a dust removal function. Background Art

[0002] Quartz sand is a common natural mineral material, mainly composed of silicon dioxide. It is formed by quartz through long-term natural weathering, water flow and other geological processes. It is mostly white, colorless or light gray. During the processing and application of quartz sand, it needs to be transported from one place to another, or transferred from one process to another. The quartz sand conveying device can stably and efficiently complete the long-distance transportation, short-distance loading and unloading, and vertical lifting of quartz sand, effectively improving production efficiency; Quartz sand usually generates a lot of dust during processing, transportation and use. This dust not only affects production efficiency, but also poses a potential threat to workers' health, the environment and the operating stability of equipment. The use of quartz sand conveying devices with dust removal function can effectively solve the problems of environmental pollution, health risks, equipment wear and product quality degradation in the process of quartz sand transportation; Chinese patent application CN115447880B discloses an intelligent dust reduction device for conveying quartz sand, including: a conveying device, a dust reduction structure, a sampling structure and a reinforcement mechanism, wherein a plurality of shielding boxes are installed on the upper side of the conveying device, and a barrier structure is provided on the upper side of each of the shielding boxes; at least one group of dust reduction structures passes through the barrier structure and moves along the corresponding shielding box; a plurality of sampling structures are respectively installed inside each shielding box; two groups of reinforcement mechanisms are installed on both sides of the inside of the corresponding shielding box, and the two groups of reinforcement mechanisms reinforce the sampling structure from both sides. The present application provides a plurality of shielding boxes on the outside of the conveying device, and the sampling structures inside the plurality of shielding boxes can detect the corresponding parts of the conveying device in the required time period, and set the working gear of the corresponding dust reduction structure in the corresponding time period according to the detection results.

[0003] The above patents and prior art also have the following defects: Since quartz sand exists in granular form, static electricity is easily generated during transportation due to the friction between particles and between particles and equipment, the insulating properties of quartz sand, the material properties of transportation equipment and the dry environment. The generation of static electricity increases the risk of fire and explosion. Existing conveying devices conduct static electricity through grounding protection wires. Dry weather can cause static electricity to accumulate faster, and the grounding wire alone may not have enough ability to offset static electricity, especially in low humidity environments. The conductivity of the air decreases, making static electricity more likely to accumulate. Summary of the invention

[0015] Working principle: Place the quartz sand to be transported on the conveyor belt, and the quartz sand can be transported through the conveyor belt. During the transportation process, collision and friction between particles will occur, thereby generating static electricity. When static electricity is generated on the conveyor belt, the electroactive polymer block can expand. When the electroactive polymer block expands, it can push one side of the folding plate to move. The movement of one side of the folding plate can drive the moving plate to move. The movement of the moving plate can drive the trapezoidal block to move. The movement of the trapezoidal block can drive the lifting block to rise. The lifting block can drive the lifting rod to rise by rising. The lifting rod can drive the lifting plate to rise by rising. The lifting plate can drive the connecting rod to rise by rising, and the connecting rod can drive the ball plug to rise by rising. After the ball plug rises, the liquid in the water tank can flow into the water pipe through the connecting pipe, and then the liquid in the water pipe can be sprayed out through the nozzle, thereby increasing the humidity of the surrounding environment and quartz sand, thereby reducing the generation of static electricity, avoiding the adsorption of static electricity on quartz sand, and affecting the conveying effect of quartz sand. When the static electricity disappears, the electroactive polymer block shrinks, and the elastic force of the damper drives the ball plug to descend, thereby closing the connecting pipe. After the quartz sand is conveyed, it falls at the feed inlet and then enters the screening box. Starting the fan can pass through The filter plate adsorbs and filters the dust of quartz sand to ensure that the conveying process is environmentally friendly and efficient. By pressing the push rod, the limit block 1 can be squeezed to move it. After the limit block 1 moves, the restriction on the limit block 2 can be released. After the restriction of the limit block 2 is released, the filter plate can be pulled out by pulling the handle. After the filter plate is pulled out, it can be convenient to clean it. After cleaning, the filter plate is pushed back and then the push rod is released. After releasing the push rod, the push rod can be reset by the elastic force of the spring. After the push rod is reset, the limit block 1 is reset by the elasticity of the elastic telescopic rod. After the limit block 1 is reset, the filter plate can be fixed by cooperating with the limit block 2. The starting motor can drive the rotating plate to rotate, the rotating plate can drive the convex block to rotate by rotating, the convex block can drive the rotating wheel to rise and fall by rotating, the rotating wheel can drive the lifting column to rise and fall by lifting, the lifting column can drive the screening box to rise and fall by lifting, and the lifting of the screening box can screen the quartz sand through the cooperation with the screening plate. After screening, the smaller quartz sand particles are discharged through the second discharge port, and the larger quartz sand particles are discharged through the first discharge port, thereby making the function of the entire conveying device more perfect, meeting the different needs of different users for the size of quartz sand particles, and reducing the burden of manual operation and improving work efficiency.

[0016] The present invention provides a quartz sand conveying device with dust removal function. It has the following beneficial effects: 1. The present invention utilizes the characteristics of electroactive polymers. When static electricity is generated, they will expand. This expansion can push the ball plug to move upward, thereby causing the liquid in the water tank to be sprayed out through the nozzle, increasing the humidity of the surrounding environment and quartz sand. This process helps to reduce the generation of static electricity and prevent static electricity from adsorbing quartz sand, thereby avoiding adverse effects on the quartz sand transportation effect. When the static electricity dissipates, the electroactive polymer will shrink, and the ball plug will drop under the elastic force of the damper to achieve the closure of the connecting pipe.

[0017] 2. The present invention drives the rotating plate to rotate through a motor, thereby driving the screening box to achieve lifting movement. The coordinated operation of the screening box and the screening plate enables the quartz sand to be effectively screened, and the fine quartz sand particles are discharged through the second discharge port, and the larger particles are discharged through the first discharge port, which improves the function of the conveying device, meets the user's demand for the diversity of quartz sand particle sizes, reduces the labor intensity of manual operation, and improves work efficiency.

[0018] 3. When the fan is started in the present invention, the filter plate can absorb and filter the dust generated by the quartz sand, ensuring that the conveying process is both environmentally friendly and efficient. By pressing the push rod, the limit block 1 can be pushed to move, thereby releasing the restriction on the limit block 2. The restriction of the limit block 2 is released, and the filter plate can be pulled out for cleaning by pulling the handle. After cleaning, the filter plate is pushed back to its original position, and the push rod is automatically reset under the action of the spring force. After the push rod is reset, the elasticity of the elastic telescopic rod will restore the limit block 1 to its initial position. Finally, the limit block 1 and the limit block 2 cooperate with each other to ensure that the filter plate is firmly fixed. BRIEF DESCRIPTION OF THE DRAWINGS
