Description

Technical Field

[0001] This invention relates to the field of air pollution technology, specifically to a waste gas purification device with detection capabilities. Background Technology

[0002] Waste gas purification devices with detection capabilities typically combine waste gas purification and online monitoring technologies to ensure that waste gas emitted by thermal power plants meets environmental standards and effectively reduces pollutant emissions.

[0003] Patent publication number CN214319504U relates to the field of waste gas treatment technology and discloses a waste gas purification device with detection effect. The device includes a purification unit, a power unit mounted on the upper surface of its outer surface, and a purification unit housing. An inlet / outlet base is fixedly connected to the left side of the outer surface of the housing, and a fixing pipe is fixedly connected to the left side of the outer surface of the inlet / outlet base. This waste gas purification device with detection effect utilizes the power unit mounted on the upper surface of the purification unit and a rotating motor installed within it. When the rotating motor is activated, it causes a rotating shaft to drive a sector gear plate to move up and down. Because the left side of the outer surface of the sector gear plate overlaps with the outer surface of the push gear rod, the push gear rod moves up and down within an upper and lower sliding groove, thereby compressing the waste gas within the purification device and thus increasing the purification rate.

[0004] In the aforementioned patent, since the left side of the outer surface of the sector gear plate overlaps with the outer surface of the push gear rod, the push gear rod moves up and down in the upper and lower sliding grooves, thereby squeezing the exhaust gas in the purification device and thus achieving the effect of improving the purification rate. However, the filter surface of the filter plate, which works for a long time, will find it difficult to achieve the original filtration effect as the working time increases, and it is difficult to switch the filter surface during the filtration period of the filter plate, which reduces the equipment's service life and filtration quality and increases the replacement frequency.

[0014] This invention provides a waste gas purification device with detection capabilities. It has the following beneficial effects:

[0015] (1) In this invention, the long rod rotates to drive the fan blades to rotate. The rotation of the fan blades increases the rate of waste gas transmission and improves the working efficiency of filtration. The rotating cylinder drives the filter cylinder to rotate. The rotation of the filter cylinder allows its filter surface to rotate, thereby switching the filtration position. This avoids the filter surface from failing to achieve its original filtration effect due to long-term work. The filtration quality of continuous work is improved by rotating and replacing the filter surface, reducing the frequency of manual replacement, increasing the work cycle and reducing time and manpower.

[0016] (2) The invention closes the circular groove on the circular plate by rotating the baffle. The closing of the circular groove prevents the gas in the filter box from leaking out when the filter cartridge is replaced, thus improving the safety and work efficiency of preventing unfiltered gas from leaking out. The circular cover is no longer limited by the curved rotating rod, so the circular cover can be opened at this time, thus preventing the safety hazards caused by the staff opening the circular cover before the air outlet is completely closed, and improving the stability and safety of the work.

[0017] (3) This invention uses the vibration of the filter cartridge to remove impurities from its surface, which avoids the problem of the filter cartridge being difficult to remove due to the adsorption of impurities on its surface when the staff replaces the filter cartridge. This improves the time for replacing the filter cartridge and increases work efficiency. The U-shaped baffle achieves the function of sealing the filter box by misaligning the round hole opened on the reset surface with the air inlet pipe, which avoids the problem of residual exhaust gas leakage in the filter box when the filter cartridge is completely removed, reduces the safety hazards to the staff, and improves the efficiency of exhaust gas treatment.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7One embodiment of the present invention is as follows: a waste gas purification device with detection effect, comprising a base 1, a filter box 2 fixedly installed on the top of the base 1, an air inlet pipe 3 fixedly penetrating the surface of the filter box 2, an exhaust fan 4 fixedly installed on the top of the base 1, a detection box 5 fixedly installed on the top of the exhaust fan 4, an exhaust pipe 6 fixedly penetrating the surface of the exhaust fan 4, a transport pipe 7 fixedly penetrating the top of the filter box 2, and a filtration device disposed inside the filter box 2, the filtration device comprising: a motor 801, a long rod 802, a fan blade 803, a rotating rod 804, a connecting block 805, a fixed circular plate 806, a sealing box 807, a sliding rod 808, a curved block 809, a fixed cylinder 810, a rotating cylinder 811, a sliding cylinder 812, a rotating block 813, a fixed block 814, and a filter cylinder 815. The motor 801 is fixedly installed inside the base 1, the long rod 802 is fixedly installed at the output end of the motor 801, the fan blade 803 is fixedly installed on the circumferential surface of the long rod 802, and the rotating rod 804 is fixedly installed inside the base 1. A spring is fixedly installed on the circumferential surface of the long rod 802. The end of the rotating rod 804 away from the long rod 802 is connected by the spring. The fixed circular plate 806 is fixedly installed on the inner wall of the filter box 2. The fixed circular plate 806 has a long groove inside. The sealing box 807 is fixedly installed on the top of the fixed circular plate 806. The sliding rod 808 is slidably installed on the inner wall of the long groove. The curved block 809 is fixedly installed on the bottom of the sliding rod 808. The fixed cylinder 810 is fixedly installed on the inner wall of the filter box 2. The rotating cylinder 811 is rotatably installed on the inner wall of the filter box 2. The sliding cylinder 812 is slidably installed on the circumferential surface of the rotating cylinder 811. The rotating block 813 is rotatably installed on the surface of the sliding rod 808. The fixed block 814 is fixedly installed on the surface of the sliding rod 808. The filter cylinder 815 is detachably installed on the inner wall of the rotating cylinder 811. The rotation increases the exhaust gas transmission rate, improves the filtration efficiency, reduces the frequency of manual replacement, increases the working cycle, and reduces time and manpower.

[0028] A second spring is provided between the sliding rod 808 and the fixed circular plate 806. The connecting block 805 contacts the curved block 809, and the sliding rod 808 is reset by the second spring.

[0029] In this embodiment, during operation: When the purification device starts, motor 801 and exhaust fan 4 are activated. Motor 801 rotates, driving long rod 802 to rotate, which in turn drives fan blades 803 to rotate. The rotation of fan blades 803 increases the rate of exhaust gas transmission, improving filtration efficiency. Long rod 802 rotates, driving rotating rod 804 to rotate, which in turn drives connecting block 805 to rotate. During the rotation of connecting block 805 from fast to slow, it contacts curved block 809 via spring 1. Curved block 809 is lifted by connecting block 805. At its fastest rotation speed, it does not contact curved block 809. 09 lifts and drives the sliding rod 808 to slide, which in turn drives the rotating block 813 to slide. The rotating block 813 then drives the rotating plate to rotate, which in turn drives the sliding cylinder 812 to rotate. The rotating cylinder 812 then drives the rotating cylinder 811 to rotate, which in turn drives the filter cylinder 815 to rotate. The rotation of the filter cylinder 815 allows its filter surface to rotate, preventing the filter surface from failing to achieve its original filtration effect due to long-term operation. By rotating the filter surface and replacing it, the filtration quality for continuous operation is improved, the frequency of manual replacement is reduced, the work cycle is increased, and time and manpower are reduced.

[0030] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the filter box 2 is further provided with a closing device for closing the air outlet pipe 6 and a reminder device for reminding the filter cartridge 815 to be replaced. The closing device includes: a square block 901, a circular groove plate 902, a thin rod 903, a baffle 904, and a rectangular block 905. A rotating plate is fixedly installed on the surface of the sliding cylinder 812. The square block 901 is fixedly installed on the surface of the rotating plate. The circular groove plate 902 is fixedly installed on the top of the filter box 2. The thin rod 903 rotates through the inner and outer walls of the sealing box 807. The baffle 904 is fixedly installed on the circumferential surface of the thin rod 903. The rectangular block 905 is fixedly installed on the circumferential surface of the thin rod 903. The closure of the circular groove can prevent the gas in the filter box 2 from leaking out when the filter cartridge 815 is replaced, thereby improving the safety and work efficiency in preventing the leakage of unfiltered gas.

[0031] The closing device also includes: a square short block 906, a round cover 907, a short rotating rod 908, and a curved rotating rod 909. The square short block 906 is fixedly installed on the circumference of the thin rod 903. The round cover 907 is detachably installed inside the filter box 2. The short rotating rod 908 is rotatably installed inside the round cover 907. The curved rotating rod 909 is fixedly installed on the circumference of the short rotating rod 908. This prevents the safety hazard caused by the operator opening the round cover 907 before the air outlet is completely closed, and improves the stability and safety of the operation.

[0032] A spring is installed between the short rotating rod 908 and the curved rotating rod 909, and a torsion spring is installed between the circular groove plate 902 and the thin rod 903. The curved rotating rod 909 is reset by the spring, and the thin rod 903 is reset by the torsion spring.

[0033] The prompting device includes: a sloping sliding rod 1001, a rotating handle 1002, a coarse rotating rod 1003, and a rotating long rod 1004. The sloping sliding rod 1001 is slidably installed through the inner and outer walls of the fixed circular plate 806. The rotating handle 1002 is rotatably installed on the surface of the circular cover 907. The coarse rotating rod 1003 rotatably passes through the inner and outer walls of the circular cover 907. The rotating long rod 1004 is fixedly installed on the circumferential surface of the coarse rotating rod 1003. This device avoids the problem of filter cartridge 815 being difficult to remove due to the adsorption of impurities on its surface when the operator replaces it, thus improving the time for replacing filter cartridge 815 and increasing work efficiency.

[0034] The warning device also includes a U-shaped baffle 1005, a base plate 1006, and an inclined block 1007. The U-shaped baffle 1005 is slidably installed on the inner wall of the filter box 2, the base plate 1006 is fixedly installed on the top of the U-shaped baffle 1005, and the inclined block 1007 is fixedly installed on the top of the base plate 1006. This avoids the problem of exhaust gas leakage when the filter cartridge 815 is completely removed, reduces the safety hazards to the staff, and improves the efficiency of exhaust gas treatment.

[0035] A spring is installed between the U-shaped baffle 1005 and the filter box 2. The inclined block 1007 contacts the filter cylinder 815, and the spring drives the U-shaped baffle 1005 to reset.

[0036] In this embodiment, during operation: the rotating plate rotates, causing the square block 901 to rotate. After the square block 901 rotates 180 degrees, it indicates that the filter cartridge 815 needs to be replaced. Before replacing the filter cartridge 815, the rotation of the square block 901 causes the rectangular block 905 to rotate, which in turn causes the thin rod 903 to rotate. The rotation of the thin rod 903 causes the baffle 904 to rotate, and the rotation of the baffle 904 closes the circular groove on the circular plate 902. The closure of the circular groove prevents gas leakage from the filter box 2 when replacing the filter cartridge 815, improving safety and work efficiency in preventing unfiltered gas leakage. The rotation of the thin rod 903 drives the square short block 906 to rotate. The square short block 906 rotates and contacts the curved rotating rod 909, pressing and rotating it. After the curved rotating rod 909 rotates, the round cover 907 can be fully opened. This avoids the situation where the round cover 907 cannot be opened if the air outlet is not fully closed. Only when the air outlet is fully closed will the curved rotating rod 909 no longer limit the round cover 907, and the round cover 907 can be opened. This prevents the safety hazard caused by the staff opening the round cover 907 before the air outlet is fully closed, and improves the stability and safety of the work.

[0037] The rectangular block 905 rotates, causing the inclined sliding rod 1001 to slide. When the inclined sliding rod 1001 slides downward, it contacts the connecting block 805. The connecting block 805 rotates and taps the inclined sliding rod 1001. Due to the vibration, the impurities on the surface of the filter cartridge 815 fall off, preventing the filter cartridge 815 from being difficult to remove due to the adsorption of impurities on its surface when the staff replaces it. This improves the time for replacing the filter cartridge 815 and increases work efficiency. When the filter cartridge 815 is completely removed, the inclined block 1007 is no longer squeezed by the force of the filter cartridge 815 and is released from its limit. The U-shaped baffle 1005 is reset by the spring 4. The U-shaped baffle 1005 achieves the function of sealing the filter box 2 by misaligning with the air inlet pipe 3 through the round hole opened on the reset surface. This avoids the problem of residual exhaust gas leakage in the filter box 2 when the filter cartridge 815 is completely removed, reduces the safety hazards to the staff, and improves the efficiency of exhaust gas treatment.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
