Description

Technical Field

[0001] This invention relates to the field of air pollution control, specifically to an environmentally friendly and efficient air pollution control vehicle. Background Technology

[0002] Air pollution control refers to treating the atmospheric environment as a whole within a specific area, unifying the planning of energy structure, industrial development, urban construction layout, etc., and comprehensively utilizing various pollution control technologies and measures, making full use of the environment's self-purification capacity to improve air quality. With social development, industrial, automotive, and residential emissions have increased, and air pollution has become increasingly serious. Relying solely on plants to purify the air is inefficient, and atmospheric particulate pollution has increasingly attracted people's attention and the country's high attention. In the process of air pollution control, spray dust suppression equipment is usually used to reduce and purify dust particles in the air by spraying water mist, thereby improving air quality and reducing air pollution.

[0003] In existing technologies, air pollution control equipment only has a dust extraction fan to remove dust particles from the air, resulting in a small range of air purification and no dust suppression function. This leads to poor air purification effect and an inability to quickly reduce dust in the air, thus failing to effectively improve air pollution and still affecting the health of workers and passersby. In addition, commonly used air pollution control equipment has a simple structure, single function, and is mostly fixed, treating pollution in one location, making it inconvenient to move.

The primary filtration mechanism includes a filter box 5, with two filters fixedly connected inside the filter box 5. The filter plate 6 and filter box 5 are connected by an air inlet pipe 7 and a connecting pipe 8. The top wall of the filter box 5 is slidably connected to a lifting frame 9. The top wall of the filter box 5 is rotatably connected to a lead screw A10 inside the lifting frame 9. The top of the lead screw A10 is fixedly connected to the output shaft of the servo motor A11. The bottom front end of the lifting frame 9 is fixedly connected to a baffle plate 12 inside the filter box 5. The baffle plate 12 contacts the filter plate 6. The baffle plate 12 is set to prevent dust leakage during pulse cleaning of the filter plate 6 and to better block dust.

[0023] A guide plate 13 is fixedly connected to the bottom wall of the rear end of the lifting frame 9. A guide groove 14 is opened on the rear side wall of the filter box 5, which is slidably connected to the guide plate 13. The guide groove 14 is opened at the center of the filter plate 6. The guide plate 13 acts as a barrier to the guide groove 14. This arrangement prevents dust from leaking out of the guide groove 14 and also fixes the pulse tube 16. A pulse control mechanism 15 is fixedly connected to the center of the guide plate 13 near the rear side wall of the filter box 5. The bottom wall of the pulse control mechanism 15 is connected to the pulse tube 16 through a conduit. The pulse tube 16 is located inside the filter plate 6.

[0024] In an optional embodiment, a fixed compartment is provided inside the protective housing 2 at the position of the air inlet 3. A leak-proof compartment 17 is fixedly connected to the left side of the fixed compartment inside the protective housing 2. A movable groove is opened on the left side wall of the leak-proof compartment 17, which is slidably connected to the connecting pipe 8. Guide rails 18 are fixedly connected to the inner walls of both the left and right ends of the leak-proof compartment 17. A slider 19 is fixedly connected to the outer wall of the filter box 5, which is slidably connected to the guide rails 18.

[0025] In this embodiment, the air inlet 3 is located in the fixed compartment and is equipped with multiple air collection pipes. The movable slot facilitates the movement of the filter box 5 and the connecting pipe 8.

[0026] In an optional embodiment, a vent is provided on the left side wall of the fixed chamber at the position of the air inlet pipe 7. The right side wall of the air inlet pipe 7 is slidably connected to the left side wall of the fixed chamber. The top end of the air inlet pipe 7 is rotatably connected to a lead screw B20 through a rotating ring. The rear end of the lead screw B20 is located outside the leak-proof chamber 17 and is fixedly connected to the output shaft of the servo motor B21. The servo motor B21 is fixedly connected to the rear side wall of the leak-proof chamber 17.

[0027] In this embodiment, the lead screw B20 is designed to facilitate the movement of the filter box 5, which in turn facilitates the adjustment of the filter box 5 in its operating state.

[0028] In an optional embodiment, the lifting frame 9 has a rotating hole inside that engages with the outer wall of the lead screw A10, the servo motor A11 is fixedly connected to the top of the protective shell 2, the inner top wall of the filter box 5 has a storage groove that engages with the baffle plate 12, the rear end of the filter box 5 is slidably connected to the left and right side walls of the pulse control mechanism 15 by setting a limiting rail 22, and the pulse control mechanism 15 is connected to the external air storage mechanism by an air pipe.

[0029] In this embodiment, the storage slot facilitates the repositioning of the barrier plate 12.

[0030] In an optional embodiment, the bottom wall of the filter box 5 has a drain port, and the front end of the bottom wall of the filter box 5 is rotatably connected to the drain port. An auxiliary spring 24 is fixedly connected to the bottom of the rear side wall of the filter box 5. The bottom of the anti-leakage chamber 17 is provided with a collection chamber 25 that engages with the collection box 4. The collection chamber 25 is provided to facilitate the removal of the collection box 4. An inlet is provided between the front end of the top of the collection chamber 25 and the bottom wall of the rear end of the anti-leakage chamber 17. The opening of the inlet facilitates the centralized treatment of dust generated during filtration. After the primary filtration mechanism filters for a certain period of time, the servo motor B21 drives the lead screw B20 to rotate. The air inlet pipe 7 moves backward with the rotation of the lead screw B20, and the air inlet pipe 7 is closed. At the same time, the opening and closing plate 23 moves to the feed inlet at the top front end of the collection chamber 25 and is removed from the limit of the bottom wall of the anti-leakage chamber 17. The opening and closing plate 23 rotates under the action of the auxiliary spring 24 and gravity, and the bottom of the filter box 5 is open. A dustproof plate 26 is fixedly connected to the bottom of the rear side wall of the filter box 5 at the feed inlet position.

[0031] In this embodiment, the opening and closing plate 23 is designed to facilitate the opening of the drain outlet after the filter box 5 has moved a certain distance. The auxiliary spring 24 is designed to prevent the opening and closing plate 23 from sticking to the bottom wall of the filter box 5. This design facilitates the opening and closing plate 23 to open. The opening and closing plate 23 moves to the feed inlet at the top front end of the collection chamber 25 and is released from the limit of the bottom wall of the anti-leakage chamber 17. The opening and closing plate 23 rotates under the action of the auxiliary spring 24 and gravity, and the bottom end of the filter box 5 is in an open state. The pulse control mechanism 15 performs high-pressure air blowing to clean the filter plate 6 through the pulse tube 16. At the same time, the servo motor A11 drives the lead screw A10 to rotate. The lifting frame 9 moves down with the rotation of the lead screw A10. The lifting frame 9 drives the baffle plate 12 and the pulse control mechanism 15 to move down. The dust adsorbed on the filter plate 6 is blown off into the collection box 4.

[0032] In an optional embodiment, the secondary filtration mechanism includes a sedimentation tank 27, with an exhaust pipe 28 connected through to the top of the sedimentation tank 27.

[0033] In this embodiment, the sedimentation tank 27 is used to reduce dust in the filtered gas, and the exhaust pipe 28 is used to discharge the gas after dust reduction.

[0034] In an optional embodiment, the gas delivery mechanism includes an air intake pump 29, which is connected to the bottom rear end of the sedimentation tank 27. A spring tube 30 is connected between the top of the air intake pump 29 and the connecting pipe 8. The operation of the air intake pump 29 delivers the gas in the primary filtration mechanism to the secondary filtration mechanism. During this process, the filter plate 6 in the filter box 5 filters the gas twice. The filtered gas enters the sedimentation tank 27 through the spring tube 30 and the air intake pump 29. The sedimentation tank 27 performs dust reduction filtration on the gas and discharges it from the exhaust pipe 28. A radiator fan 31 is provided on the top of the chassis 1 near the air intake pump 29. Both servo motors A11 and B21 are equipped with control modules and are connected to an external control assembly. A storage compartment 32 is provided on the top of the chassis 1 below the air intake window 3. A locking plate 33 is rotatably connected to the side wall of the protective shell 2 at the storage compartment 32.

[0035] In this embodiment, the spring tube 30 facilitates the movement of the filter box 5 by the connecting tube 8, the cooling fan 31 dissipates the heat generated by the suction pump 29 during operation, and the storage compartment 32 facilitates the storage of tools.

[0036] During operation, the suction pump 29 transports the gas from the primary filtration mechanism to the secondary filtration mechanism. During this process, the filter plates 6 within the filter box 5 filter the gas twice. The filtered gas then passes through the spring tube 30 and the suction pump 29 into the sedimentation tank 27. The sedimentation tank 27 performs dust removal filtration on the gas and discharges it through the exhaust pipe 28. After the primary filtration mechanism has filtered for a certain period, the servo motor B21 drives the lead screw B20 to rotate. The intake pipe 7, following the rotation of the lead screw B20, moves the filter box 5 backward. At this time, the intake pipe 7 is closed. The opening and closing plate 23 moves to the feed inlet at the top front end of the collection chamber 25 and disengages from the limit of the bottom wall of the anti-leakage chamber 17. The opening and closing plate 23 rotates under the action of the auxiliary spring 24 and gravity, and the bottom end of the filter box 5 is in the open state. The pulse control mechanism 15 performs high-pressure air blowing to clean the filter plate 6 through the pulse tube 16. At the same time, the servo motor A11 drives the lead screw A10 to rotate, and the lifting frame 9 moves down with the rotation of the lead screw A10. The lifting frame 9 drives the baffle plate 12 and the pulse control mechanism 15 to move down, and the dust adsorbed on the filter plate 6 is blown off into the collection box 4.
