Description

Technical Field

[0001] This application relates to the field of material transportation technology, and in particular to a dustproof conveyor for conveying aggregates and gravel. Background Technology

[0002] Aggregate and gravel are very important building materials, which are made up of raw materials of different volumes and weights, ranging from large pebbles or gravel to small fine sand and debris. This means that some dust will be generated during the transportation of aggregate and gravel. In order to avoid this dust from polluting the surrounding working environment, dust covers are installed on the top of traditional aggregate and gravel conveyors to prevent dust from leaking out. This dust prevention method is currently a commonly used one, which is simple in structure, convenient to use and inexpensive.

[0003] Although existing dust control methods for aggregate and sand conveyors have many advantages, they still have certain limitations in actual use. When the conveyor belt rotates, it drives the airflow inside the dust cover to flow synchronously, and the airflow carries dust out from the opening of the dust cover, still polluting the surrounding working environment. In addition, the position of the rollers supporting the conveyor belt is fixed, and the conveyor belt has a certain degree of flexibility. The material between the rollers causes the conveyor belt to descend due to its own weight, and the conveyor belt returns to its original height after contacting the rollers, causing the material at the top to be thrown up, thus generating more dust and aggravating the pollution problem. In view of this, this application proposes a dust control conveyor for aggregate and sand conveyors to solve the above-mentioned problems. Summary of the Invention

[0004] This application adopts the following technical solution: a dustproof conveyor for conveying aggregates and gravel, comprising a top plate, a support base fixedly installed at the bottom of the top plate by welding, ribs fixedly installed at the top of the top plate near both ends by bolts, a power shaft movably sleeved at the top of the ribs by bearings, a conveyor belt movably sleeved on the outer surface of the power shaft, stroke holes drilled on both sides of the top of the top plate by drilling, the stroke holes being arranged in pairs in a linear array, the stroke holes penetrating the top plate and extending into the interior of the support base, a bearing device movably installed inside the stroke holes by telescopic cooperation, a bypass hole drilled on one side of the outer surface of the support base by drilling, the bypass hole communicating with the support base, dustproof devices fixedly installed on both sides of the top plate by bolts, a water supply device fixedly installed at the bottom of the top plate by welding, and a flow limiting device fixedly installed at the bottom of the top plate near one end by bolts.

[0005] Furthermore, the bearing device includes a stroke rod, which is movably installed inside the stroke hole via a telescopic fit. A connecting seat is fixedly installed on the top of the stroke rod by welding. A bearing shaft is movably sleeved inside the connecting seat via a bearing connection. The bearing shaft is sleeved with the conveyor belt. A support spring is fixedly installed on the bottom of the connecting seat at the position outside the stroke rod by a snap-fit. The bottom of the support spring is connected to the top of the top plate by a snap-fit. A base plate is fixedly installed on the bottom of the stroke rod by welding. A mating hole is drilled in the middle of the top of the base plate by a drilling machine. The mating hole is connected to the flow limiting device via a telescopic fit. A stroke plate is fixedly installed on the bottom of the base plate at the position on one side of the mating hole by welding. A guide hole is drilled on one side of the stroke plate by a drilling machine.

[0006] Furthermore, the base plate extends to the outside of the support base through a bypass hole.

[0007] Furthermore, the dustproof device includes a connecting bracket, and two connecting brackets are respectively installed on both sides of the top plate. A dustproof cover is fixedly installed on the top of the connecting bracket by welding. An atomizing nozzle is fixedly sleeved on the top of the dustproof cover by shaft hole fitting. A flow-flow plate is fixedly installed on the top of the inner wall of the dustproof cover by welding. The flow-flow plate is arrayed along the extension direction of the connecting bracket axis.

[0008] Furthermore, the flow plate is arranged at an angle of 45 degrees to the horizontal plane.

[0009] Furthermore, the water supply device includes a water pump and a water supply pipe. The input end of the water pump is connected to the water supply equipment through a pipe. The output end of the water pump is fixedly installed with a main pipe by a snap-fit. One end of the main pipe is in a closed state. A guide pipe is fixedly installed on the outer surface of the main pipe and is connected to the main pipe. One end of the guide pipe is connected to a guide hole by a snap-fit. One end of the water supply pipe is fixedly connected to a flow limiting device, and the other end of the water supply pipe is connected to the input end of the atomizing nozzle.

[0010] Furthermore, the flow limiting device includes a fixing plate, which is fixedly installed at the bottom of the top plate by welding. The fixing plate is movably sleeved inside the mating hole. Limiting slide rails are fixedly installed on both sides of the front of the fixing plate near the bottom by welding. A travel plate is movably installed inside the limiting slide rails. A flow limiting hole is drilled on the front of the limiting slide rail near the bottom by a drilling machine. One end of the flow limiting hole is fixedly connected to the water supply pipe by snap-fit.

[0011] Furthermore, when the travel plate is in its initial state, the guide holes and the flow-limiting holes are in an alternating state.

[0012] This application has the following beneficial effects.

[0013] 1. A flow plate is fixedly installed on the top of the inner wall of the dust cover by welding, and the other end of the water supply pipe is connected to the input end of the atomizing nozzle. During operation, the water supply device pressurizes water and inputs it into the flow plate. After being atomized by the flow plate, the water enters the interior of the dust cover. The small droplets in the water mist suppress the formation of dust inside the dust cover. In traditional equipment, dust is only prevented by installing a dust cover. However, the conveyor belt will drive the airflow inside the dust cover during operation, which will still carry out the dust inside the dust cover and affect the surrounding working environment. This application document avoids this problem and improves the dust prevention performance of the device.

[0014] 2. The travel rod is movably installed inside the travel hole via a telescopic mechanism. The bottom of the connecting seat is located on the outside of the travel rod and a support spring is fixedly installed by snap-fit. The bottom of the support spring is connected to the top of the top plate by snap-fit, so that the top of the conveyor belt carries the aggregate and gravel and rotates under the drive of the power shaft. When the aggregate and gravel move to the top of the carrying device, the entire carrying device moves vertically downward under the action of gravity. This buffers the aggregate and gravel on the top of the conveyor belt during transportation, reduces the degree of bumps on the aggregate and gravel, and reduces the dust generated by the bumps during transportation. This avoids the problem of reduced dust suppression efficiency due to excessive dust, thus improving the environmental friendliness of the device.

[0015] 3. One end of the guide pipe is connected to the guide hole via a snap-fit ​​connection, and one end of the water supply pipe is fixedly connected to the flow limiting hole. The travel plate is movably installed inside the limit slide rail. When the travel plate is in its initial state, the guide hole and the flow limiting hole are staggered. When the entire bearing device moves vertically downwards, the guide hole and the flow limiting hole are connected. The water pumped by the water supply device is pumped into the atomizing nozzle through the main pipe, guide pipe, guide hole, flow limiting hole, and water supply pipe, generating water mist inside the dust cover. The greater the weight of the aggregate and gravel carried on the top of the conveyor belt, the greater the connection between the guide hole and the flow limiting hole. This results in a greater mass of aggregate and gravel carried by the conveyor belt, generating more dust and increasing the spray volume of the dust suppression device at the top. This ensures that the spray volume of the dust suppression device is proportional to the amount of material carried on the top of the conveyor belt, allowing the device to adjust the spray volume according to the specific amount of material. This optimizes the water consumption of the device, saving water and reducing the operating cost.

[0016] 4. A flow-reducing plate is fixedly installed on the top of the inner wall of the dust cover by welding. The flow-reducing plate is arrayed along the extension direction of the connecting support axis. The flow-reducing plate is arranged at an angle of 45 degrees with the horizontal plane. During the operation of the device, the conveyor belt rotates and drives the airflow inside the dust cover to flow rapidly. During the flow, the airflow will come into contact with the flow-reducing plate, thereby forming a vortex on one side of the flow-reducing plate, which has a flow-blocking effect. Through the flow-blocking effect of multiple sets of flow-reducing plates, the airflow inside the dust cover is obstructed, preventing the airflow from carrying dust away from the dust cover quickly and reducing the dust suppression effect. This improves the dust suppression efficiency of the device. In addition, the generated vortex can change the original unidirectional airflow structure and disturb the airflow inside the dust cover, so that the water mist generated by the atomizing nozzle can mix better with the dust and meet and settle, further improving the dust suppression efficiency.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] A dustproof conveyor for transporting aggregates and gravel; please refer to [reference needed]. Figures 1-4The system includes a top plate 1, a support base 2 fixedly installed at the bottom of the top plate 1 by welding, ribs 3 fixedly installed at the top of the top of the top plate 1 near both ends by bolts, a power shaft 4 movably sleeved at the top of the ribs 3 by bearings, a conveyor belt 5 movably sleeved on the outer surface of the power shaft 4, stroke holes 6 drilled on both sides of the top of the top plate 1 by drilling, two stroke holes 6 are arranged in a linear array, the stroke holes 6 penetrate the top plate 1 and extend into the interior of the support base 2, a bearing device 7 is movably installed inside the stroke holes 6 by telescopic cooperation, a bypass hole 8 is drilled on one side of the outer surface of the support base 2 by drilling, the bypass hole 8 is connected to the support base 2, dustproof devices 9 are fixedly installed on both sides of the top plate 1 by bolts, a water supply device 10 is fixedly installed at the bottom of the top plate 1 by welding, and a flow limiting device 11 is fixedly installed at the bottom of the top plate 1 near one end by bolts.

[0037] Please refer to Figures 1-7 The bearing device 7 includes a stroke rod 71, which is movably installed inside the stroke hole 6 via a telescopic fit. A connecting seat 72 is fixedly installed on the top of the stroke rod 71 by welding. A bearing shaft 73 is movably sleeved inside the connecting seat 72 via a bearing connection. The bearing shaft 73 is sleeved with the conveyor belt 5. A support spring 74 is fixedly installed on the bottom of the connecting seat 72, located outside the stroke rod 71, via a snap-fit ​​connection. The bottom of the support spring 74 is connected to the top of the top plate 1 via a snap-fit ​​connection. This allows the top of the conveyor belt 5 to carry the aggregate and gravel and rotate under the drive of the power shaft 4. When the aggregate and gravel move to the top of the bearing device 7, the entire bearing device 7 moves vertically downward under the action of gravity. The device is designed to buffer the aggregates and gravel on top of the conveyor belt 5 during transportation, reducing the degree of bumps and dust generated by the bumps. This avoids excessive dust and reduces the dust suppression efficiency, thus improving the environmental friendliness of the device. The bottom of the stroke rod 71 is fixedly installed with a base plate 75 by welding. A mating hole 76 is drilled in the middle of the top of the base plate 75. The mating hole 76 is connected to the flow limiting device 11 by telescopic cooperation. A stroke plate 77 is fixedly installed on the bottom of the base plate 75 on one side of the mating hole 76 by welding. A guide hole 78 is drilled on one side of the stroke plate 77.

[0038] Please refer to Figures 1-7 The base plate 75 extends to the outside of the support seat 2 through the bypass hole 8.

[0039] Please refer to Figures 8-10The dustproof device 9 includes a connecting bracket 91. There are two connecting brackets 91 installed on both sides of the top plate 1. A dust cover 92 is fixedly installed on the top of the connecting bracket 91 by welding. An atomizing nozzle 93 is fixedly sleeved on the top of the dust cover 92 by shaft hole fitting. A flow-flow plate 94 is fixedly installed on the top of the inner wall of the dust cover 92 by welding. The flow-flow plate 94 is arrayed along the extension direction of the axis of the connecting bracket 91.

[0040] Please refer to Figures 1-7 The flow-encircling plate 94 is arranged at an angle of 45 degrees to the horizontal plane. During operation, the conveyor belt 5 rotates and drives the airflow inside the dust cover 92 to flow rapidly. During the flow, the airflow comes into contact with the flow-encircling plate 94, forming a vortex on one side of the flow-encircling plate 94, which has a flow-blocking effect. Through the flow-blocking effect of multiple sets of flow-encircling plates 94, the airflow inside the dust cover 92 is obstructed, preventing the airflow from carrying dust away from the dust cover 92 quickly and reducing the dust suppression effect. This improves the dust suppression efficiency of the device. In addition, the vortex generated can change the original unidirectional airflow structure and disturb the airflow inside the dust cover 92, so that the water mist generated by the atomizing nozzle 93 can mix better with the dust and meet and settle, further improving the dust suppression efficiency.

[0041] Please refer to Figures 1-12 The water supply device 10 includes a water pump 101 and a water supply pipe 102. The input end of the water pump 101 is connected to the water supply equipment through a pipe. The output end of the water pump 101 is fixedly installed with a main pipe 103 by a snap-fit. One end of the main pipe 103 is in a closed state. A guide pipe 104 is fixedly installed on the outer surface of the main pipe 103 and is connected to the main pipe 103. One end of the guide pipe 104 is connected to the guide hole 78 by a snap-fit. One end of the water supply pipe 102 is fixedly connected to the flow limiting device 11, and the other end of the water supply pipe 102 is connected to the input end of the atomizing nozzle 93. In this device, during operation, the water supply device 10 pressurizes water and inputs it into the flow plate 94. After being atomized by the flow plate 94, the water enters the interior of the dustproof device 9. The small droplets in the water mist suppress the formation of dust inside the dustproof device 9. In traditional equipment, dust is only prevented by installing a dust cover 92. However, the conveyor belt 5 drives the airflow inside the dust cover 92 during operation, which still carries out the dust inside the dust cover 92 and affects the surrounding working environment. This application effectively avoids this problem and improves the dustproof performance of the device.

[0042] Please refer to Figures 5-7 and Figures 11-15The flow limiting device 11 includes a fixing plate 111, which is fixedly installed at the bottom of the top plate 1 by welding. The fixing plate 111 is movably sleeved inside the mating hole 76. Limiting slide rails 112 are fixedly installed on both sides of the front of the fixing plate 111 near the bottom by welding. The travel plate 77 is movably installed inside the limiting slide rail 112. A flow limiting hole 113 is drilled on the front of the limiting slide rail 112 near the bottom by drilling. One end of the flow limiting hole 113 is fixedly connected to the water supply pipe 102 by snap-fit.

[0043] Please refer to Figures 1-15 When the travel plate 77 is in its initial state, the guide hole 78 and the flow limiting hole 113 are in an interleaved state. When the entire bearing device 7 moves vertically downward, the guide hole 78 and the flow limiting hole 113 are in a connected state. The water pumped by the water supply device 10 is pumped into the interior of the atomizing nozzle 93 through the main pipe 103, the guide pipe 104, the guide hole 78, the flow limiting hole 113 and the water supply pipe 102, and water mist is generated inside the dust cover 92. The greater the weight of the aggregate and gravel carried on the top of the conveyor belt 5, the greater the degree of connection between the guide hole 78 and the flow limiting hole 113, which makes the mass of the aggregate and gravel carried by the conveyor belt 5 greater, the more dust generated, and the more spray volume generated by the dustproof device 9 at the top. This ensures that the spray volume of the dustproof device 9 is proportional to the amount of material carried on the top of the conveyor belt 5, so that the device can adjust the spray volume according to the specific amount of material, thereby achieving the optimal level of water consumption, saving water and reducing the operating cost of the device.

[0044] The method of using this invention is as follows:

[0045] During operation, the water supply device 10 pressurizes water and inputs it into the flow plate 94. After being atomized by the flow plate 94, the water enters the interior of the dustproof device 9, thereby using the small droplets in the water mist to suppress dust formation inside the dustproof device 9. The top of the conveyor belt 5 carries aggregates and rotates under the drive of the power shaft 4. When the aggregates move to the top of the carrying device 7, the carrying device 7 moves vertically downward under the action of gravity, thus buffering the aggregates on the top of the conveyor belt 5 during transportation, reducing the degree of bumps on the aggregates, and mitigating the dust generated by the bumps during transportation. When the carrying device 7 moves vertically downward, the guide hole 78 and the flow restriction hole 113 are in a connected state. The water pumped by the water supply device 10 is pumped into the interior of the atomizing nozzle 93 through the main pipe 103, guide pipe 104, guide hole 78, flow restriction hole 113, and water supply pipe 102. Water mist is generated inside the dust cover 92. The greater the weight of the aggregate and gravel carried on the top of the conveyor belt 5, the greater the connection between the guide hole 78 and the restrictor hole 113. This results in a larger mass of aggregate and gravel carried by the conveyor belt 5, more dust being generated, and a greater spray volume from the dust control device 9 at the top. This ensures that the spray volume of the dust control device 9 is proportional to the amount of material carried on the top of the conveyor belt 5, allowing the device to adjust the spray volume according to the specific amount of material, thereby achieving the optimal water consumption level. The rotation of the conveyor belt 5 drives the airflow inside the dust cover 92 to flow rapidly. During the flow, the airflow will come into contact with the flow-encircling plate 94, forming a vortex on one side of the flow-encircling plate 94, which has a flow-blocking effect. Through the flow-blocking effect of multiple sets of flow-encircling plates 94, the airflow inside the dust cover 92 is obstructed, and the generated vortex can change the original unidirectional airflow structure, disturbing the airflow inside the dust cover 92, so that the water mist generated by the atomizing nozzle 93 can mix better with the dust and come into contact with and settle.
