Description

Technical Field

[0001] This invention relates to the field of thermal power plant technology, and more particularly to a heat dissipation device for thermal power plants. Background Technology

[0002] A thermal power plant is a power generation facility that uses combustible materials as fuel to produce electricity. It can provide a reliable energy source. Thermal power plants generate a lot of heat during the power generation process, so heat dissipation devices are installed in thermal power plants to dissipate heat and ensure the normal operation of the system.

[0003] Heat dissipation devices are typically installed next to the equipment in thermal power plants to dissipate heat. These devices are usually equipped with filters to filter dust from the hot air and prevent it from being released into the environment. In addition, the devices are also equipped with cleaning mechanisms to clean the dust off the filters and ensure smooth ventilation. However, when cleaning the filters, the dust can easily scatter, polluting the surrounding environment and potentially posing a health risk to workers. Summary of the Invention

[0004] To overcome the drawback that dust easily scatters when cleaning the filter screen, polluting the surrounding environment and potentially threatening the health of workers, this invention provides a heat dissipation device for thermal power plants.

[0005] A heat dissipation device for thermal power plants includes a base plate, casters, a mounting box, a filter screen, an intake fan, an exhaust box, an exhaust pipe, a cleaning mechanism, a collection mechanism, and a dust suction mechanism.

[0006] As a further preferred embodiment, the cleaning mechanism includes guide rods, cleaning brushes, lead screws, and a motor. Two guide rods are connected to both the front and rear sides of the mounting box. The two guide rods on the front side are slidably connected to the cleaning brushes, and the two guide rods on the rear side are also slidably connected to the cleaning brushes. Lead screws are rotatably connected to both the front and rear sides of the mounting box. The lead screws and cleaning brushes are connected by threads, and the two lead screws are driven by a pulley set. A motor is installed on the mounting box, and the output shaft of the motor is connected to the lead screws on the front side to drive the lead screws to rotate. The lead screws can drive the cleaning brushes to move up and down, and the cleaning brushes clean the dust on the filter screen.

[0007] As a further preferred embodiment, the collection mechanism includes a sliding box, a filter box, and an opening and closing assembly. The sliding box is slidably connected to the lower part of the mounting box, and the filter box is placed inside the sliding box. A feed opening is opened at the lower part of the mounting box, and the dust cleaned by the cleaning brush falls into the filter box through the feed opening. The mounting box is equipped with an opening and closing assembly for controlling the opening and closing of the feed opening.

[0008] As a further preferred embodiment, the opening and closing assembly includes a first guide frame, a sliding frame, a sealing plate, a spring, and a push block. Two first guide frames are connected to the mounting box, and a sliding frame is slidably connected to both first guide frames. A sealing plate is connected to the sliding frame, which extends into the mounting box and seals the feed opening. A spring connects the first guide frames and the sealing plate. A push block is connected to the front cleaning brush. The push block is used to push the sliding frame forward, which in turn drives the sealing plate forward, opening the feed opening.

[0009] As a further preferred embodiment, the vacuuming mechanism includes a housing, a suction pipe, a rigid pipe, a second guide frame, a fixed plate, a sliding plate, an airbag, an inlet pipe, an outlet pipe, and a one-way valve. The housing is connected to the bottom of the base plate, and the housing and the sliding housing are connected. Eight suction pipes are connected to the housing, and the lower ends of the eight suction pipes are connected to the rigid pipe. Two second guide frames are connected to the mounting box, and a fixed plate is connected to the top of each second guide frame. A sliding plate is slidably connected to each second guide frame. Through openings are opened on both the left and right sides of the mounting box, and the sliding plate extends into the mounting box through the through openings. The sliding plate is connected to the cleaning brush. An airbag is connected between the bottom of the fixed plate and the bottom of the sliding plate. An inlet pipe and an outlet pipe are connected to the top of the fixed plate. Both the inlet pipe and the outlet pipe are connected to the airbag. The inlet pipe is connected to the rigid pipe, and a one-way valve is installed on both the inlet pipe and the outlet pipe.

[0010] As a further preferred embodiment, a fixing mechanism is also included, which includes guide rods, a sliding plate, a pad, and a pushing component. Two guide rods are connected to the bottom of the base plate, and a sliding plate is slidably connected to both guide rods. A pad is connected to the bottom of the sliding plate, and a pushing component is provided on the base plate for pushing the sliding plate downward.

[0011] As a further preferred embodiment, the actuating component includes a screw and a knob. The screw is threadedly connected to the base plate, and the screw and the slide plate are rotatably connected. The knob is connected to the upper end of the screw.

[0012] As a further preferred embodiment, it also includes a support frame, with the support frame for supporting the exhaust box connected to the base plate, and the support frame and the exhaust box are connected.

[0013] The beneficial effects are as follows: 1. The present invention can draw in the hot air generated in the production environment of the thermal power plant through the suction fan. The hot air is discharged through the exhaust channel to dissipate heat from the production environment in the thermal power plant. The filter screen can filter the dust in the hot air to prevent the dust from being discharged to the outside and affecting the environment. The cleaning brush can clean the dust on the filter screen to ensure smooth ventilation. The air bag can suck the dust cleaned by the cleaning brush into the filter box to prevent the dust from spreading everywhere and affecting the surrounding environment, and can also prevent the staff from inhaling the dust.

[0014] 2. The filter box can collect the dust cleaned by the cleaning brush, making it easy to clean later. The sealing plate can close the feed opening to prevent dust from floating out of the filter box. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0029] like Figures 1-10 As shown, a heat dissipation device for a thermal power plant includes a base plate 1, casters 2, a mounting box 3, a filter screen 4, suction fans 5, an exhaust box 6, an exhaust pipe 7, a cleaning mechanism, a collection mechanism, and a dust collection mechanism. Casters 2 are symmetrically installed on both sides of the bottom of the base plate 1. The mounting box 3 is bolted to the front top of the base plate 1. The filter screen 4 is connected to the center of the mounting box 3. Four suction fans 5 are bolted to the rear of the mounting box 3, arranged in a rectangular array. The exhaust box 6 is bolted to the rear of the mounting box 3, and all four suction fans 5 are located inside the exhaust box 6. An exhaust pipe 7 is connected to the center of the rear of the exhaust box 6. The mounting box 3 is equipped with a cleaning mechanism for cleaning dust from the filter screen 4, a collection mechanism for collecting the dust removed by the cleaning mechanism, and a dust collection mechanism for sucking up the dust removed by the cleaning mechanism.

[0030] like Figure 4 and Figure 5As shown, the cleaning mechanism includes guide rods 8, cleaning brushes 9, lead screws 10, and a motor 11. Guide rods 8 are symmetrically connected to the front and rear sides of the mounting box 3. The two guide rods 8 on the front side are slidably connected to the cleaning brushes 9, and the rear side of the front cleaning brushes 9 contacts the front side of the filter screen 4. The two guide rods 8 on the rear side are also slidably connected to the cleaning brushes 9, and the front side of the rear cleaning brushes 9 contacts the rear side of the filter screen 4. The two guide rods 8 guide the cleaning brushes 9 together to prevent them from tilting. The guide rods 8 are vertically set, and the cleaning brushes 9 can move up and down along the guide rods 8 to clean the dust on the filter screen 4. Lead screws 10 are rotatably connected to the front and rear sides of the middle of the mounting box 3. The two lead screws 10 are respectively connected to the two cleaning brushes 9 by threads. The two lead screws 10 are driven by a pulley set. The motor 11 is bolted to the top center of the mounting box 3. The output shaft of the motor 11 is connected to the upper end of the lead screw 10 on the front side by a coupling.

[0031] like Figures 6-8 As shown, the collection mechanism includes a sliding box 12, a filter box 13, and an opening and closing assembly. The sliding box 12 is slidably connected to the lower part of the mounting box 3, and the filter box 13 is placed inside the sliding box 12. The lower part of the mounting box 3 has a feed opening 14, and the mounting box 3 is provided with an opening and closing assembly for controlling the opening and closing of the feed opening 14.

[0032] like Figure 6 and Figure 8 As shown, the opening and closing assembly includes a first guide frame 15, a sliding frame 16, a sealing plate 161, a spring 17, and a push block 18. The first guide frames 15 are bolted to both sides of the mounting box 3. The sliding frame 16 is slidably connected to both first guide frames 15, and the two first guide frames 15 guide the sliding frame 16 together, improving its stability. A sealing plate 161 is connected to the lower rear side of the sliding frame 16. The sealing plate 161 extends into the mounting box 3 and seals the feed opening 14. The upper and lower parts of the first guide frames 15 are fitted with… A spring 17 is provided, with its two ends connected to the first guide frame 15 and the sealing plate 161 respectively. The spring 17 is fitted on the guide frame to prevent it from bending. Push blocks 18 are connected to the left and right sides of the front cleaning brush 9. The lower part of the push blocks 18 is tilted backward. The tilted position of the push blocks 18 can push the sliding frame 16 forward. The sliding frame 16 drives the sealing plate 161 forward to open the feed opening 14. After the feed opening 14 is opened, the push blocks 18 continue to push the sliding frame 16 to keep the feed opening 14 open.

[0033] like Figure 9 and Figure 10As shown, the vacuuming mechanism includes a housing 19, suction pipes 20, rigid pipes 21, a second guide frame 22, a fixed plate 23, a sliding plate 24, an airbag 25, an inlet pipe 26, an outlet pipe 27, and a one-way valve 28. The housing 19 is bolted to the bottom front of the base plate 1. The top of the housing 19 is open. The sliding box 12 is vertically connected, and the housing 19 and the sliding box 12 are connected. Eight suction pipes 20 are evenly spaced at the bottom of the housing 19, and the lower ends of the eight suction pipes 20 are connected to the rigid pipe 21. The second guide frame 22 is bolted to both the left and right sides of the mounting box 3. The top of the second guide frame 22 is connected to the fixed plate 23. The sliding plate 24 is slidably connected to the second guide frame 22. The mounting box 3 has through openings 241 on both the left and right sides, through which the sliding plate 24 extends. The airbag 25 is installed inside the housing 3, and both sliding plates 24 are connected to the front cleaning brush 9. An airbag 25 is connected between the bottom of the fixed plate 23 and the bottom of the sliding plate 24. An air inlet pipe 26 and an air outlet pipe 27 are connected to the top of the fixed plate 23. Both the air inlet pipe 26 and the air outlet pipe 27 are connected to the airbag 25. Both air inlet pipes 26 are connected to the rear side of the rigid pipe 21, and the air inlet pipe 26 and the rigid pipe 21 are connected. One-way valves 28 are installed on both the air inlet pipe 26 and the air outlet pipe 27. Under the action of the one-way valve 28 on the air inlet pipe 26, the air in the air inlet pipe 26 will only enter the airbag 25, and the air in the airbag 25 will not enter the air inlet pipe 26. Under the action of the one-way valve 28 on the air outlet pipe 27, the air in the airbag 25 will only be discharged through the air outlet pipe 27, and the outside air will not enter the airbag 25 through the air outlet pipe 27.

[0034] like Figure 11 and Figure 12 As shown, it also includes a fixing mechanism, which includes guide rods 29, a slide plate 30, pads 31, and a pushing component. Guide rods 29 are connected to the left and right sides of the bottom of the base plate 1. The slide plate 30 is slidably connected to the two guide rods 29. The two guide rods 29 guide the slide plate 30 together, which can improve the stability of the slide plate 30. Pads 31 are symmetrically connected to the left and right sides of the bottom of the slide plate 30. There are four pads 31 in total, and the bottom of the four pads 31 is provided with a rubber layer, which can better resist the movement of the base plate 1 and prevent the base plate 1 from moving randomly. The base plate 1 is provided with a pushing component for pushing the slide plate 30 to move downward.

[0035] like Figure 12 As shown, the pushing component includes a screw 32 and a knob 33. The screw 32 is threadedly connected to the middle of the base plate 1. The lower end of the screw 32 is rotatably connected to the middle of the top of the slide plate 30. The knob 33 is connected to the upper end of the screw 32.

[0036] like Figure 3 As shown, it also includes a support frame 34, which is bolted to the middle of the rear side of the top of the base plate 1. The support frame 34 is connected to the exhaust box 6.

[0037] The staff moved the device into the power plant, then connected the exhaust pipe 7 to the exhaust channel. By turning the screw 32 with the knob 33, the screw 32 caused the sliding plate 30 to move downwards, which in turn caused the pad 31 to move downwards, bringing the rubber layer at the bottom of the pad 31 into contact with the ground. This created resistance to the movement of the base plate 1, preventing it from moving arbitrarily. The suction fan 5 extracted the hot air generated in the power plant's production environment. The hot air was discharged into the exhaust channel through the exhaust box 6 and exhaust pipe 7, and finally exited through the exhaust channel, thus cooling the production environment inside the power plant. The filter screen 4 filtered out dust from the hot air, preventing dust from entering the plant. Dust emitted into the environment affects the environment. The support frame 34 can support the exhaust box 6, improving its stability. When it is necessary to clean the dust on the filter screen 4, the output shaft of the control motor 11 drives the front lead screw 10 to rotate. The front lead screw 10 drives the rear lead screw 10 to rotate through the pulley set. The lead screw 10 drives the cleaning brush 9 to move downward. The cleaning brush 9 can clean the dust on the filter screen 4, ensuring smooth ventilation. The front cleaning brush 9 will drive the push block 18 to move downward. The tilted position of the push block 18 pushes the sliding frame 16 forward, the spring 17 is stretched, and the sliding frame 16 drives the sealing plate 161 forward. The feed opening 14 is opened by the movement of the cleaning brush 9, allowing the dust collected by the cleaning brush 9 to fall into the filter box 13 for collection and subsequent cleaning. The front cleaning brush 9 can also move the sliding plate 24 downwards, extending the airbag 25. The airbag 25 draws air through the air inlet pipe 26, rigid pipe 21, and suction pipe 20, sucking the dust collected by the cleaning brush 9 into the filter box 13. This prevents dust from scattering and affecting the surrounding environment, and also prevents workers from inhaling dust. The filter box 13 filters the dust, preventing it from entering the air inlet pipe 26, rigid pipe 21, and suction pipe 20. The output shaft of the motor 11 drives the front lead screw 10 to rotate in the opposite direction. The front lead screw 10 drives the rear lead screw 10 to rotate in the opposite direction through the pulley set. The lead screw 10 drives the cleaning brush 9 to move upward. The front cleaning brush 9 drives the push block 18 and the sliding plate 24 to move upward. The sliding plate 24 squeezes the air bag 25. The air in the air bag 25 is discharged through the air outlet pipe 27. After the push block 18 and the sliding frame 16 are disengaged, the sliding frame 16 moves backward to reset under the action of the spring 17. The sliding frame 16 drives the sealing plate 161 to move backward to reset. The sealing plate 161 closes the feed opening 14 to prevent dust in the filter box 13 from floating out.

[0038] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
