Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and more specifically to a waste gas treatment device for environmental engineering. Background Technology

[0002] In environmental engineering, waste gas refers to the mixture of gases containing pollutants emitted into the atmosphere during human activities such as industrial production, energy utilization, transportation, and daily life. These waste gases are complex and diverse, including inorganic pollutants such as sulfur dioxide, nitrogen oxides, and carbon monoxide, which mostly originate from the combustion of fossil fuels such as coal and oil and can cause environmental problems such as acid rain and photochemical smog, harming ecosystems and human health; as well as organic and inorganic composite pollutants such as volatile organic compounds (VOCs) and particulate matter (PM), which are commonly found in industries such as chemical, coating, and printing.

[0003] Existing exhaust gas treatment devices require filtering airborne debris before use to prevent it from clogging the treatment structure. However, the air filter structure is also prone to clogging after prolonged use, which reduces exhaust gas emission efficiency. Furthermore, the filter structure is inconvenient to unclog and requires cumbersome replacement. Summary of the Invention

[0004] The purpose of this invention is to provide an exhaust gas treatment device for environmental engineering, so as to solve the problem of inconvenience in clearing blockages in the exhaust gas emission filter structure in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an environmental engineering waste gas treatment device, comprising an exhaust pipe, a connecting pipe fixedly installed on the exhaust pipe, the exhaust pipe and the connecting pipe being used for the emission of environmental engineering waste gas, and further comprising: a main body mechanism, disposed on the exhaust pipe, for filtering impurities in the waste gas, the main body mechanism including a cleaning box fixedly installed on the exhaust pipe, the cleaning box having a filter screen fixedly installed inside; a sweeping mechanism, disposed on the cleaning box, for sweeping impurities on the filter screen, the sweeping mechanism including a connecting box fixedly installed on the side wall of the cleaning box, the connecting box having a mounting frame slidably installed inside, the mounting frame having two cleaning roller brushes rotatably installed on the mounting frame; and a support mechanism, fixedly disposed between the exhaust pipe and the connecting box, for reinforcing and supporting the cleaning box and the connecting box, the support mechanism including a support rod fixedly disposed between the exhaust pipe and the connecting box.

[0006] Furthermore, the main structure also includes a waste pipe fixedly disposed at the bottom of the exhaust pipe, and a sealing cap is screwed onto the bottom of the waste pipe.

[0007] Furthermore, the cleaning mechanism also includes two electric push rods symmetrically fixed inside the connecting box, and the output ends of the two electric push rods are both fixedly mounted on the mounting frame.

[0008] Furthermore, the cleaning mechanism also includes two rotating shafts symmetrically rotatably mounted on the mounting frame, and the two cleaning roller brushes are symmetrically rotatably mounted on the mounting frame via the two rotating shafts.

[0009] Furthermore, a motor is fixedly installed on the side wall of the mounting bracket on one side of the electric push rod, and a drive shaft is fixedly installed at the output end of the motor; and the drive shaft passes through the interior of the mounting bracket.

[0010] Furthermore, driven gears are fixedly mounted on both rotating shafts, and a driving gear is fixedly mounted on the end of the drive shaft; and both driven gears are meshed with the driving gear.

[0011] Furthermore, a protective cover is fixedly provided on the side wall of the mounting bracket.

[0012] Furthermore, the support mechanism also includes a support ring fixedly disposed on the side wall of the exhaust pipe, and one end of the support rod is fixedly disposed on the exhaust pipe through the support ring.

[0013] Compared with existing technologies, the present invention provides an environmental engineering waste gas treatment device. By having the waste gas enter the exhaust pipe through a connecting pipe and flow through the cleaning box, a fixed filter screen inside the box filters out impurities in the waste gas. The filtered waste gas continues to be transported along the exhaust pipe to the treatment terminal. The intercepted impurities fall into the waste pipe at the bottom of the exhaust pipe under gravity. The sealing cap at the bottom of the waste pipe allows for periodic opening to clean accumulated impurities. When the filter screen may become clogged due to impurities, the cleaning mechanism can be activated: an electric push rod inside the connecting box pushes the mounting frame towards the cleaning box, causing two rotating cleaning rollers on the mounting frame to extend below the filter screen. Subsequently, the motor starts, driving the drive shaft to rotate the drive gear, which in turn engages the two auxiliary gears. The rotating gear causes the cleaning roller brush to rotate, scrubbing the filter screen and removing surface debris. The debris swept off also falls into the waste pipe. The entire device is stably connected to the exhaust pipe and the connecting box through a triangular support structure formed by the support rod and support ring, ensuring structural stability during operation. The advantages of this device are: it can achieve online automatic cleaning of the filter screen without disassembly or shutdown, significantly improving the continuity and efficiency of exhaust gas treatment; the extension and rotation design of the cleaning roller brush makes the cleaning process comprehensive and controllable, effectively preventing filter screen clogging; the combination of the waste pipe and sealing cover facilitates the centralized collection and cleaning of debris, making maintenance simple; the overall structure is reinforced by the support mechanism, resulting in a long service life, making it particularly suitable for continuously operating exhaust gas treatment systems in environmental engineering.

[0023] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] Example 1:

[0026] This invention provides an environmental engineering waste gas treatment device, including an exhaust pipe 1, a connecting pipe 3 fixedly installed on the exhaust pipe 1, the exhaust pipe 1 and the connecting pipe 3 for the emission of environmental engineering waste gas, and further including: a main body mechanism, installed on the exhaust pipe 1, for filtering impurities in the waste gas, the main body mechanism including a cleaning box 2 fixedly installed on the exhaust pipe 1, the cleaning box 2 having a filter screen 9 fixedly installed inside; a cleaning mechanism, installed on the cleaning box 2, for cleaning impurities on the filter screen 9, the cleaning mechanism including a connecting box 8 fixedly installed on the side wall of the cleaning box 2, the connecting box 8 having a mounting frame 12 slidably installed inside, the mounting frame 12 having two cleaning roller brushes 11 rotatably installed on the mounting frame 12; and a support mechanism, fixedly installed between the exhaust pipe 1 and the connecting box 8, for reinforcing and supporting the cleaning box 2 and the connecting box 8, the support mechanism including a support rod 7 fixedly installed between the exhaust pipe 1 and the connecting box 8;

[0027] Meanwhile, the exhaust gas first enters the exhaust pipe 1 through the connecting pipe 3. When it flows through the cleaning box 2, the filter screen 9 fixed inside filters the impurities in the exhaust gas. The filtered exhaust gas continues to be transported to the treatment terminal along the exhaust pipe 1. The intercepted impurities fall into the waste pipe 4 at the bottom of the exhaust pipe 1 under the action of gravity. The sealing cover 5 at the bottom of the waste pipe 4 can be opened periodically to clean the accumulated impurities. When the filter screen 9 may be clogged due to the adhesion of impurities, the cleaning mechanism can be activated: the electric push rod 13 in the connecting box 8 pushes the mounting frame 12 to move towards the cleaning box 2, so that the two cleaning roller brushes 11 rotatably set on the mounting frame 12 extend below the filter screen 9. Then the motor 15 starts, and drives the drive gear 17 to rotate through the drive shaft 18, which in turn meshes with the two driven gears 16, so that the cleaning mechanism can be activated. The roller brush 11 rotates to scrub the filter screen 9, removing surface debris. The debris swept off also falls into the waste pipe 4. The entire device is stably connected to the exhaust pipe 1 and the connecting box 8 through a triangular support structure formed by the support rod 7 and the support ring 6, ensuring structural stability during operation. The advantages of this device are: it can realize online automatic cleaning of the filter screen 9 without disassembly or shutdown, significantly improving the continuity and efficiency of exhaust gas treatment; the extension and rotation design of the cleaning roller brush 11 makes the cleaning process comprehensive and controllable, effectively preventing the filter screen 9 from clogging; the combination of the waste pipe 4 and the sealing cover 5 facilitates the centralized collection and cleaning of debris, making maintenance simple; the overall structure is reinforced by the support mechanism, resulting in a long service life, making it especially suitable for continuously operating exhaust gas treatment systems in environmental engineering.

[0028] refer to Figure 1 and Figure 2 The main structure includes an exhaust pipe 1, a connecting pipe 3, a cleaning box 2, a filter screen 9, a waste pipe 4, and a sealing cover 5;

[0029] By providing an exhaust pipe 1, the environmental engineering waste gas can be easily discharged and treated through the exhaust pipe 1. A connecting pipe 3 is fixedly connected to the side wall of the exhaust pipe 1, so that after the environmental engineering waste gas is generated, it can be transmitted to the exhaust pipe 1 through the connecting pipe 3, and then discharged to the treatment terminal for purification treatment through the exhaust pipe 1. A cleaning box 2 is fixedly connected to the exhaust pipe 1, and a filter screen 9 is fixedly connected inside the cleaning box 2. After the environmental engineering waste gas is transmitted to the exhaust pipe 1 through the connecting pipe 3, the filter screen 9 in the cleaning box 2 can filter the impurities in the waste gas, thereby preventing the impurities in the waste gas from affecting the waste gas treatment terminal.

[0030] Meanwhile, a waste pipe 4 is fixedly connected to the bottom of the exhaust pipe 1, and a sealing cap 5 is screwed onto the bottom of the waste pipe 4. When the connecting pipe 3 and the exhaust pipe 1 are conveying and discharging exhaust gas, the bottom of the waste pipe 4 can be screwed closed by the sealing cap 5. This allows impurities in the air to be filtered and blocked by the filter screen 9. When impurities fall, they can fall into the waste pipe 4 for collection. When it is necessary to process the impurities in the waste pipe 4, the sealing cap 5 can be screwed open to facilitate the discharge and processing of the impurities in the waste pipe 4.

[0031] Secondly, the connecting pipe 3, the exhaust pipe 1, and the waste pipe 4 are all the same. When the debris at the filter screen 9 falls into the connecting pipe 3, since the connecting pipe 3 is connected to the environmental engineering waste gas outlet, there will be airflow to blow the debris that fell into the connecting pipe 3 into the waste pipe 4, so as to facilitate the collection of debris in the waste pipe 4 for centralized treatment.

[0032] Example 2:

[0033] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The cleaning mechanism includes a connecting box 8, an electric push rod 13, a mounting bracket 12, a rotating shaft 10, a cleaning roller brush 11, a motor 15, and a drive shaft 18;

[0034] A connecting box 8 is fixedly connected to the side wall of the cleaning box 2, and a mounting frame 12 is slidably connected inside the connecting box 8. Two electric push rods 13 are fixedly connected inside the connecting box 8, and the output ends of the two electric push rods 13 are fixedly connected to the side wall of the mounting frame 12. When in use, the mounting frame 12 can be slidably adjusted inside the connecting box 8 by the extension and retraction of the two electric push rods 13. Two cleaning roller brushes 11 are rotatably connected to the mounting frame 12. When the electric push rods 13 drive the mounting frame 12 to slide and adjust, the two cleaning roller brushes 11 can slide and be placed inside the connecting box 8 with the mounting frame 12, or slide and extend to the bottom of the filter screen 9 for use. This makes it easy for the two cleaning roller brushes 11 to be placed inside the connecting box 8 and to extend and rotate to clean the filter screen 9.

[0035] Meanwhile, a motor 15 is fixedly connected to the side wall of the mounting bracket 12 on one side of the electric push rod 13, and a drive shaft 18 is fixedly connected to the output end of the motor 15. The drive shaft 18 passes through the interior of the mounting bracket 12, so that the output end of the motor 15 can drive the drive shaft 18 to rotate inside the mounting bracket 12. A drive gear 17 is fixedly connected to the end of the drive shaft 18, so that the output end of the motor 15 can drive the drive gear 17 to rotate through the drive shaft 18.

[0036] Secondly, on the side wall of the mounting bracket 12 opposite to the motor 15, two rotating shafts 10 are rotatably connected, allowing the two cleaning roller brushes 11 to be fixedly connected to the rotating shafts 10, thus enabling them to rotate with the rotating shafts 10. Driven gears 16 are fixedly connected to the side walls of both rotating shafts 10, and these two driven gears 16 mesh with the driving gear 17 fixedly connected to the end of the drive shaft 18. This allows the motor 15 to drive the driving gear 17 to rotate, which in turn drives the two cleaning roller brushes 11 via the two driven gears 16. The filter screen 9 is rotated so that when cleaning the debris on the filter screen 9, the electric push rod 13 can first push the mounting frame 12 and the two cleaning roller brushes 11 to slide from the inside of the connecting box 8, so that the two cleaning roller brushes 11 slide to the bottom of the filter screen 9. At this time, the mounting frame 12 is still located inside the connecting box 8 to support the cleaning roller brushes 11. Then, the motor 15 drives the two cleaning roller brushes 11 to rotate, so that the two cleaning roller brushes 11 can rotate to clean the debris on the filter screen 9, thereby preventing the filter screen 9 from becoming clogged. The cleaned debris can fall into the waste pipe 4 for collection and treatment.

[0037] In addition, a protective cover 14 is fixedly connected to the mounting bracket 12. During use, when the mounting bracket 12 and the two cleaning roller brushes 11 are retracted into the connecting box 8, dust will fall into the connecting box 8. At this time, the protective cover 14 can protect the components on the mounting bracket 12. When the mounting bracket 12 slides out of the connecting box 8, the mounting bracket 12 will push out the debris that has fallen into the connecting box 8. At this time, the protective cover 14 can still protect the components on the mounting bracket 12, thereby extending the service life of the components on the mounting bracket 12.

[0038] Example 3:

[0039] refer to Figure 1 and Figure 2 The support mechanism includes a support rod 7 and a support ring 6;

[0040] By fixing a support ring 6 to the side wall of the exhaust pipe 1, the support ring 6 can reinforce the side wall of the exhaust pipe 1. A support rod 7 is fixedly connected to the bottom of the connecting box 8, and the other end of the support rod 7 is fixedly connected to the support ring 6, so that the exhaust pipe 1, the connecting box 8 and the support rod 7 can form a triangular support structure. This facilitates the stable installation of the cleaning box 2 and the connecting box 8 on the exhaust pipe 1 for use, thereby improving the safety of the internal components of the cleaning box 2 and the connecting box 8.

[0041] Working principle: First, during normal operation, the environmental engineering waste gas enters the exhaust pipe 1 system through the connecting pipe 3, and then enters the cleaning box 2 located on the exhaust pipe 1. The filter screen 9 fixed in the cleaning box 2 physically intercepts and filters the particulate matter and impurities in the waste gas. The purified waste gas continues to flow along the exhaust pipe 1 to the subsequent treatment unit. During the filtration process, the intercepted impurities gradually adhere to the surface of the filter screen 9 or fall into the waste pipe 4 at the bottom of the exhaust pipe 1 for temporary storage under their own weight. The bottom of the waste pipe 4 is equipped with a screw-on sealing cap 5, which can be opened during regular maintenance to clean the accumulated impurities. When the filter... When the ventilation efficiency of filter screen 9 decreases due to prolonged operation, the cleaning mechanism can be activated for online cleaning: First, the two symmetrically arranged electric push rods 13 inside the control connection box 8 extend synchronously, pushing the sliding mounting bracket 12 to move along the inner wall of the connection box 8 towards the cleaning box 2. This causes the two cleaning roller brushes 11, which are rotatably mounted on the mounting bracket 12 via the rotating shaft 10, to extend from inside the connection box 8 and move accurately to the position below filter screen 9. Subsequently, the motor 15 fixed to the side wall of the mounting bracket 12 is activated. The motor 15 drives the drive shaft 18 fixed to its output end to rotate, thereby driving the drive gear 1 fixed to the end of the drive shaft 18. 7. Rotation; The driving gear 17 meshes with two driven gears 16 respectively fixed on two rotating shafts 10, thereby synchronously transmitting power to the two cleaning roller brushes 11, causing them to rotate and brush in opposite directions or in the same direction below the filter screen 9; During this process, the bristles of the cleaning roller brushes 11 thoroughly clean the surface of the filter screen 9, removing debris that is blocked or attached to it. The removed debris falls downwards into the waste pipe 4 under the action of gravity for collection; After the cleaning task is completed, the electric push rod 13 retracts, driving the mounting frame 12 and the cleaning roller brushes 11 to return to their original position inside the connecting box 8. At this time, the protective cover 1 fixed to the side wall of the mounting frame 12... 4 provides dust protection for transmission components such as motor 15 and gear set; the stability of the entire device is ensured by the support mechanism: the support ring 6 fixed to the side wall of exhaust pipe 1 is rigidly connected to the bottom of the connecting box 8 by the support rod 7, forming a stable triangular support structure, which effectively resists vibration and load during equipment operation and cleaning, ensuring the long-term reliable operation of cleaning box 2, connecting box 8 and internal mechanisms; in summary, the device realizes continuous operation of exhaust gas filtration and automatic filter cleaning, greatly reducing the system downtime maintenance needs caused by filter screen 9 blockage, and improving exhaust gas treatment efficiency and system automation level.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
