Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust prevention device for a coal conveying system in a thermal power plant. Background Technology

[0002] A thermal power plant is a factory that uses combustible materials as fuel to produce electricity. The basic production process of a thermal power plant is as follows: when fuel is burned, it heats water to generate steam, which converts the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. Then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] When a thermal power plant uses coal as fuel to produce electricity, it needs to transport the coal. However, when the coal is transported by conveyor belt, a large amount of dust is generated, causing smoke and dust to permeate the area around the conveyor belt and affecting the surrounding working environment. Therefore, in order to solve this problem, a dust prevention device for the coal conveying system of a thermal power plant is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust prevention device for coal conveying systems in thermal power plants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust control device for a coal conveying system in a thermal power plant includes a strip plate. A fixed plate is installed on the top of the strip plate. Multi-stage electric telescopic rods are installed on both sides of the fixed plate. A fixing bar is installed at the end of the piston rod of the multi-stage electric telescopic rod. A tarpaulin is installed between the fixing bar and the strip plate. A flow channel is opened in the fixing bar. Several air holes communicating with the flow channel are opened at the bottom of the fixing bar. A blower and vacuum cleaner are installed on the side of the fixing bar away from the tarpaulin. The output end of the blower and vacuum cleaner is connected to the flow channel. A support mechanism for supporting the strip plate is provided at the bottom of the strip plate.

[0007] Preferably, mounting strips are installed on the opposite sides of the fixing strip and the strip plate, and the tarpaulin is installed between the two mounting strips.

[0008] Preferably, a fixing block is fixedly connected to the end of the piston rod of the multi-stage electric telescopic rod, and the fixing block is installed on the top of the fixing bar.

[0009] Preferably, a reinforcing block is installed at the end of the piston rod of the multi-stage electric telescopic rod, and the reinforcing block is installed on the side of the fixed block close to the multi-stage electric telescopic rod.

[0010] Preferably, the support mechanism includes two sets of base plates, which are located on both sides of the strip plate. An electric push rod is installed on the top of the base plate, and the piston rod end of the electric push rod is connected to a support plate. The top of the support plate is installed at the bottom of the strip plate.

[0011] Preferably, a bearing plate is installed at the end of the piston rod of the electric push rod, and a support plate is installed obliquely on the top of the bearing plate.

[0012] Preferably, the bottom plate has mounting holes at the top, and flame-retardant fabric is sewn onto the lower surface of the tarpaulin.

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

[0014] 1. In this utility model, the blow-and-suction dual-purpose vacuum cleaner uses the flow channel inside the fixed strip and the air hole at the bottom of the fixed strip to perform dust suction above the conveyor belt. The smoke and dust generated on the conveyor belt when transporting coal are blocked by the strip plate and tarpaulin and then drift to both sides. The smoke and dust drifting to both sides can be absorbed by the air hole, and thus the smoke and dust can be absorbed by the blow-and-suction dual-purpose vacuum cleaner through the air hole and flow channel. This can block and collect the smoke and dust generated on the conveyor belt when transporting coal and absorb it into the blow-and-suction dual-purpose vacuum cleaner, preventing the smoke and dust from drifting away when the conveyor belt is transporting coal.

[0015] 2: In this utility model, the piston rod of the multi-stage electric telescopic rod pushes the fixed strip to move away from the strip plate, thereby causing the tarpaulin between the two mounting strips to unfold. The strip plate and the tarpaulin are used to block the smoke and dust generated when the coal is transported on the conveyor belt. The smoke and dust generated when the coal is transported can be blocked between the strip plate, the tarpaulin and the conveyor belt, preventing the smoke and dust generated when the coal is transported from drifting to the outside and affecting the outside air environment and working environment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A dust control device for a coal conveying system in a thermal power plant includes a strip plate 1, a fixed plate 2 installed on the top of the strip plate 1, multi-stage electric telescopic rods 3 installed on both sides of the fixed plate 2, a fixed strip 5 installed at the end of the piston rod of the multi-stage electric telescopic rod 3, a tarpaulin 7 installed between the fixed strip 5 and the strip plate 1, a flow channel is opened in the fixed strip 5, and several air holes 14 connected to the flow channel are opened at the bottom of the fixed strip 5, a blower and vacuum cleaner 8 is installed on the side of the fixed strip 5 away from the tarpaulin 7, the output end of the blower and vacuum cleaner 8 is connected to the flow channel, and a support mechanism for supporting the strip plate 1 is provided at the bottom of the strip plate 1.

[0023] As a technical optimization of this utility model, mounting strips 6 are installed on the opposite sides of the fixing strip 5 and the strip plate 1, and the tarpaulin 7 is installed between the two mounting strips 6. The mounting strips 6 installed on the opposite sides of the fixing strip 5 and the strip plate 1 facilitate the connection of the two ends of the tarpaulin 7 to the strip plate 1 and the fixing strip 5 respectively.

[0024] As a technical optimization of this utility model, a fixing block 4 is fixedly connected to the end of the piston rod of the multi-stage electric telescopic rod 3. The fixing block 4 is installed on the top of the fixing strip 5, and the fixing block 4 can facilitate the connection between the fixing strip 5 and the piston rod of the multi-stage electric telescopic rod 3.

[0025] As a technical optimization of this utility model, a reinforcing block 15 is installed at the end of the piston rod of the multi-stage electric telescopic rod 3. The reinforcing block 15 is installed on the side of the fixed block 4 close to the multi-stage electric telescopic rod 3. The reinforcing block 15 can increase the connection strength between the end of the piston rod of the multi-stage electric telescopic rod 3 and the fixed block 4.

[0026] As a technical optimization of this utility model, the support mechanism includes two sets of base plates 12, which are located on both sides of the strip plate 1. An electric push rod 11 is installed on the top of the base plate 12. The piston rod end of the electric push rod 11 is connected to a support plate 9. The top of the support plate 9 is installed at the bottom of the strip plate 1. The base plate 12, the electric push rod 11 and the support plate 9 can not only provide support for this device, but also adjust the height of the bearing plate 10 through the electric push rod 11, thereby adjusting the height of the strip plate 1 and the tarpaulin 7. The height of the strip plate 1 and the tarpaulin 7 can be adjusted to a suitable height so that the distance between the strip plate 1 and the tarpaulin 7 and the conveyor belt is appropriate.

[0027] As a technical optimization of this utility model, a bearing plate 10 is installed at the end of the piston rod of the electric push rod 11, and a support plate 9 is installed obliquely on the top of the bearing plate 10. The bearing plate 10 can facilitate the connection between the support plate 9 and the piston rod of the electric push rod 11.

[0028] As a technical optimization of this utility model, the bottom plate 12 has an installation hole 13 at the top, and the lower surface of the tarpaulin 7 is sewn with flame-retardant cloth. The flame-retardant cloth sewn on the lower surface of the tarpaulin 7 can prevent the tarpaulin 7 from being ignited when the coal on the conveyor belt catches fire, thus preventing a larger fire.

[0029] When this utility model is in use, and coal needs to be transported, the device is installed on the coal conveyor belt. The device is fixed by the mounting holes 13 on the two sets of base plates 12, so that the two sets of base plates 12 are located on both sides of the coal conveyor belt, and the strip plate 1 is located above the conveyor belt.

[0030] When using a conveyor belt to transport coal, two multi-stage electric telescopic rods 3 are activated simultaneously. The piston rods of the multi-stage electric telescopic rods 3 push the fixed strip 5 to move away from the strip plate 1, thereby causing the tarpaulin 7 between the two mounting strips 6 to unfold. The strip plate 1 and the tarpaulin 7 are used to block the smoke and dust generated when the coal is transported on the conveyor belt. The smoke and dust generated when the coal is transported can be blocked between the strip plate 1, the tarpaulin 7 and the conveyor belt, preventing the smoke and dust generated when the coal is transported from drifting to the outside and affecting the outside air environment and working environment.

[0031] Furthermore, while the conveyor belt is conveying coal, the blower-vacuum dual-purpose vacuum cleaner 8 is activated to perform dust collection. The blower-vacuum dual-purpose vacuum cleaner 8 collects dust above the conveyor belt through the flow channel in the fixing strip 5 and the air hole 14 at the bottom of the fixing strip 5. The smoke and dust generated on the conveyor belt when conveying coal are blocked by the strip plate 1 and the tarpaulin 7 and then dispersed to both sides. The smoke and dust dispersed to both sides can be absorbed by the air hole 14, and then the smoke and dust are absorbed by the blower-vacuum dual-purpose vacuum cleaner 8 through the air hole 14 and the flow channel. This can block and collect the smoke and dust generated on the conveyor belt when conveying coal and absorb it into the blower-vacuum dual-purpose vacuum cleaner 8, thus preventing the smoke and dust from being dispersed when the conveyor belt is conveying coal.

[0032] Furthermore, when the conveyor belt is not conveying coal, the coal dust remaining on the conveyor belt can be removed by activating the blowing function of the blower / vacuum cleaner 8. The blower / vacuum cleaner 8 blows air onto the conveyor belt through the flow channel and air holes 14, which can disperse the coal dust remaining on the conveyor belt. After the dispersed coal dust is blocked by the strip plate 1 and the tarpaulin 7, the vacuuming function of the blower / vacuum cleaner 8 is quickly activated to absorb and collect the dispersed coal dust again. This can clean the coal dust remaining on the conveyor belt, keep the conveyor belt clean, and prevent the coal dust remaining on the conveyor belt from affecting its cleanliness, making it convenient for the next use of the conveyor belt.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
