Description

Technical Field

[0001] The present invention relates to the technical field of air pollution treatment, and in particular to a purification device for producing and processing water purifier filter elements. Background Art

[0002] Water purifier filter cartridges are the core components of water purifiers, primarily used to filter impurities, pollutants, bacteria, viruses, heavy metals, and other harmful substances from water, thereby providing clean, safe drinking water. Different types of filter cartridges remove different contaminants from water through physical filtration, chemical adsorption, ion exchange, or biodegradation. The production process of water purifier filter cartridges produces some atmospherically harmful substances, such as tar, organic waste gases, and volatile organic compounds.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Example 1, with reference to Figure 1-3 A purification device for producing and processing water purifier filter elements includes a catalytic oxidation box 1, an air collecting box 12, and an outer tube 10. The outer tube 10 is rotatably arranged between the catalytic oxidation box 1 and the air collecting box 12. An inner sieve tube 21 is provided on the inner side of the outer tube 10. Air holes are evenly arranged on the inner sieve tube 21. The inner sieve tube 21 is connected to the inner side of the outer tube 10 through a column. The interlayer between the inner sieve tube 21 and the outer tube 10 is filled with activated carbon particles.

[0028] A fixed pipe 19 is fixedly installed on the inner side of the gas collecting box 12 through a bracket 13. An arc-shaped groove 18 is provided on the outer side of the fixed pipe 19. A filter bag 16 is wound in the arc-shaped groove 18. The filter bag 16 is arranged in a ring shape with both ends being open. Figure 6 A plurality of paddles 20 are evenly arranged at one end of the fixed tube 19, and the plurality of paddles 20 are distributed in a circular array, and one end of the paddle 20 extends to the inner side of the inner sieve tube 21, and the inner sieve tube 21 is movably arranged between the pores formed by the inner sieve tube 21 and the paddle 20.

[0029] During the production process of water purifier filter elements, tar, volatile organic compounds and other harmful gas substances will be produced. During this process, when treating some exhaust gases in a targeted manner, catalytic oxidation is used, which requires the use of catalysts and oxidants. However, these volatile organic compounds will adhere to the surface of the catalyst and oxidant, resulting in a decrease in treatment efficiency.

[0030] To this end, the inner sieve tube 21 is connected to the inner side of the outer tube 10 by means of a column connection. Since both ends of the outer tube 10 are closed, the gas gathered from the gas collecting box 12 will pass through the inner sieve tube 21. At this time, the filter bag 16 with openings at both ends will fit on the inner wall of the inner sieve tube 21. At the same time, the multiple paddles 20 extending from the inside of the fixed tube 19 are distributed in a circular array and extend together to the inner side of the inner sieve tube 21. At this time, the filter bag 16 is sleeved on the outside of the multiple paddles 20. At the same time, the filter bag 16 is located between the paddles 20 and the inner sieve tube 21. In this way, the gas entering from the inner sieve tube 21 can effectively pass through the filter bag 16 and enter the interlayer between the inner sieve tube 21 and the outer tube 10. In this process, the tar can be effectively adsorbed on the surface of the filter bag 16. When the adsorbed exhaust gas enters the interlayer between the inner sieve tube 21 and the outer tube 10, since the interlayer is filled with activated carbon particles, the volatile organic compounds in the exhaust gas are adsorbed by the activated carbon particles, and the exhaust gas is discharged from the air outlet 22 into the catalytic oxidation box 1 to catalytically oxidize other pollutants in the exhaust gas.

[0031] Example 2, reference Figure 4 The difference between this embodiment and embodiment 1 is that one end of the outer tube 10 extends to the inner side of the catalytic oxidation box 1, a plurality of air outlet holes 22 are evenly opened on the outer tube 10 outside the catalytic oxidation box 1, a motor 4 is installed on the outer wall of the catalytic oxidation box 1, a winding wheel 23 is fixedly installed at the end of the output shaft of the motor 4, and the filter bag 16 comes out from one end of the outer tube 10 and is wound on the winding wheel 23, and a seal 2 is provided at the connection between the outer tube 10 and the catalytic oxidation box 1 and the gas collecting box 12, and the end of the outer tube 10 away from the fixed tube 19 is tapered, and one end of the filter bag 16 is pulled out from the tapered position.

[0032] Connecting frames 15 are distributed in an annular array on the outside of the outer tube 10 , and rollers 17 are installed at the bottom of each connecting frame 15 . The rollers 17 fit the filter bag 16 to the outside of the fixed tube 19 .

[0033] After the filter bag 16 absorbs the tar for a period of time, the tar will be densely distributed on the surface of the filter bag 16 inside the inner sieve tube 21, and needs to be processed in time to prevent the speed of gas entry from decreasing.

[0034] For this purpose, a corresponding arc groove 18 is provided on the outside of the fixed tube 19, and the winding cross section of the filter bag 16 is as follows: Figure 8 As shown, the wound filter bag 16 is located on the inner side of the arc groove 18, and the other end of the filter bag 16 passes through the inner screen tube 21 and comes out from the other end of the outer tube 10. At the same time, one end of the filter bag 16 that has passed through is fixed on the reel 23. The power supply of the control motor 4 is started intermittently, driving the reel 23 to pull the filter bag 16 out from the inner side of the inner screen tube 21. In this way, a new filter bag 16 will reappear on the inner side of the inner screen tube 21. When the filter bag 16 is dragged, the wound filter bag 16 on the outer side of the arc groove 18 is 6 will flip over, and during the flipping process, the filter bag 16 is transported. At the same time, multiple groups of connecting frames 15 are provided on the outer tube 10. The bottom of the connecting frame 15 is provided with a roller 17 with unrestricted rotation. When the filter bag 16 moves, the roller 17 will press against the filter bag 16 in the arc groove 18, and at the same time, the extracted single-layer filter bag 16 will press against the outer end position of the fixed tube 19, so that the filter bag 16 can move stably until the filter bag 16 inside the original inner screen tube 21 is replaced.

[0035] Example 3, reference Figure 5 and Figure 7 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that an outer ring gear 5 is fixedly mounted on the outer side of the outer tube 10, an electric telescopic rod 9 is fixedly mounted on the lower end of the catalytic oxidation box 1, and a rack 8 is fixedly mounted on the upper part of the electric telescopic rod 9. The rack 8 is located on one side of the outer ring gear 5, and the outer ring gear 5 and the rack 8 are meshed with each other. Baffles 7 are vertically symmetrically arranged on both sides of the rack 8, and the outer ring gear 5 is located between the two baffles 7.

[0036] An upper storage box 24 and a lower storage box 14 are symmetrically arranged on the outside of the air collecting box 12. The upper storage box 24 and the lower storage box 14 are located on the upper and lower sides of the outer tube 10, and the bottom of the upper storage box 24 and the upper part of the lower storage box 14 are respectively in contact with the outer surface of the outer tube 10. The upper storage box 24, the upper and lower ends of the outer tube 10 and the exchange hole 11 are between the lower and upper ends of the lower storage box 14. The outer shell 3 is installed on the outer wall of the catalytic oxidation box 1, and the rack 8 and the outer gear ring 5 are both located on the inner side of the outer shell 3. A discharge port is provided at the bottom of the lower storage box 14, and a feeding port is provided at the top of the upper storage box 24.

[0037] When activated carbon is adsorbing volatile organic compounds, the activated carbon particles need to be replaced after a period of time. Previously, the equipment needed to be disassembled and the activated carbon particles replaced. This method is inefficient and easily discharges untreated exhaust gas directly into the air.

[0038] To this end, two lower storage boxes 14 and upper storage boxes 24 of the same size are provided on the outside of the gas collecting box 12. The inside of the upper storage box 24 is filled with activated carbon particles that have not participated in the adsorption, and the lower storage box 14 and the upper storage box 24 are respectively provided with a discharge port and a feeding port. After a period of time, the electric telescopic rod 9 is started, and the rack 8 is driven by the electric telescopic rod 9 to move up and down, so that the outer gear ring 5 can move with the outer tube 10 to rotate, and the baffles 7 provided on both sides of the rack 8 can prevent the outer gear ring 5 from deflecting. When the outer tube 10 is rotated to a certain angle, the lower storage box 1 4 and the exchange hole 11 on the upper storage box 24 coincide with the exchange hole 11 on the outer tube 10. At this time, under the action of gravity, the activated carbon particles in the upper storage box 24 enter the interlayer between the outer tube 10 and the inner sieve tube 21, and the activated carbon particles originally in the interlayer flow along the exchange hole 11 at the bottom into the lower storage box 14 below for storage, thereby ensuring that the activated carbon particles can adsorb volatile organic compounds and at the same time ensuring that the gas entering the catalytic oxidation box 1 will not cover the surface of the catalyst and the oxidant, thereby ensuring the treatment effect of the exhaust gas and preventing the occurrence of air pollution.

[0039] The working principle of the device is: During the production process of water purifier filter elements, tar, volatile organic compounds and other harmful gas substances will be produced. During this process, when treating some exhaust gases in a targeted manner, catalytic oxidation is used, which requires the use of catalysts and oxidants. However, these volatile organic compounds will adhere to the surface of the catalyst and oxidant, resulting in a decrease in treatment efficiency.

[0040] To this end, the inner sieve tube 21 is connected to the inner side of the outer tube 10 by means of a column connection. Since both ends of the outer tube 10 are closed, the gas gathered from the gas collecting box 12 will pass through the inner sieve tube 21. At this time, the filter bag 16 with openings at both ends will fit on the inner wall of the inner sieve tube 21. At the same time, the multiple paddles 20 extending from the inside of the fixed tube 19 are distributed in a circular array and extend together to the inner side of the inner sieve tube 21. At this time, the filter bag 16 is sleeved on the outside of the multiple paddles 20. At the same time, the filter bag 16 is located between the paddles 20 and the inner sieve tube 21. In this way, the gas entering from the inner sieve tube 21 can effectively pass through the filter bag 16 and enter the interlayer between the inner sieve tube 21 and the outer tube 10. In this process, the tar can be effectively adsorbed on the surface of the filter bag 16. When the adsorbed exhaust gas enters the interlayer between the inner sieve tube 21 and the outer tube 10, since the interlayer is filled with activated carbon particles, the volatile organic compounds in the exhaust gas are adsorbed by the activated carbon particles, and the exhaust gas is discharged from the air outlet 22 into the catalytic oxidation box 1 to catalytically oxidize other pollutants in the exhaust gas.

[0041] After the filter bag 16 absorbs the tar for a period of time, the tar will be densely distributed on the surface of the filter bag 16 inside the inner sieve tube 21, and needs to be processed in time to prevent the speed of gas entry from decreasing.

[0042] For this purpose, a corresponding arc groove 18 is provided on the outside of the fixed tube 19, and the winding cross section of the filter bag 16 is as follows: Figure 8 As shown, the wound filter bag 16 is located on the inner side of the arc groove 18, and the other end of the filter bag 16 passes through the inner screen tube 21 and comes out from the other end of the outer tube 10. At the same time, one end of the filter bag 16 that has passed through is fixed on the reel 23. The power supply of the control motor 4 is started intermittently, driving the reel 23 to pull the filter bag 16 out from the inner side of the inner screen tube 21. In this way, a new filter bag 16 will reappear on the inner side of the inner screen tube 21. When the filter bag 16 is dragged, the wound filter bag 16 on the outer side of the arc groove 18 is 6 will flip over, and during the flipping process, the filter bag 16 is transported. At the same time, multiple groups of connecting frames 15 are provided on the outer tube 10. The bottom of the connecting frame 15 is provided with a roller 17 with unrestricted rotation. When the filter bag 16 moves, the roller 17 will press against the filter bag 16 in the arc groove 18, and at the same time, the extracted single-layer filter bag 16 will press against the outer end position of the fixed tube 19, so that the filter bag 16 can move stably until the filter bag 16 inside the original inner screen tube 21 is replaced.

[0043] When activated carbon is adsorbing volatile organic compounds, the activated carbon particles need to be replaced after a period of time. Previously, the equipment needed to be disassembled and the activated carbon particles replaced. This method is inefficient and easily discharges untreated exhaust gas directly into the air.

[0044] To this end, two lower storage boxes 14 and upper storage boxes 24 of the same size are provided on the outside of the gas collecting box 12. The inside of the upper storage box 24 is filled with activated carbon particles that have not participated in the adsorption, and the lower storage box 14 and the upper storage box 24 are respectively provided with a discharge port and a feeding port. After a period of time, the electric telescopic rod 9 is started, and the rack 8 is driven by the electric telescopic rod 9 to move up and down, so that the outer gear ring 5 can move with the outer tube 10 to rotate, and the baffles 7 provided on both sides of the rack 8 can prevent the outer gear ring 5 from deflecting. When the outer tube 10 is rotated to a certain angle, the lower storage box 1 4 and the exchange hole 11 on the upper storage box 24 coincide with the exchange hole 11 on the outer tube 10. At this time, under the action of gravity, the activated carbon particles in the upper storage box 24 enter the interlayer between the outer tube 10 and the inner sieve tube 21, and the activated carbon particles originally in the interlayer flow along the exchange hole 11 at the bottom into the lower storage box 14 below for storage, thereby ensuring that the activated carbon particles can adsorb volatile organic compounds and at the same time ensuring that the gas entering the catalytic oxidation box 1 will not cover the surface of the catalyst and the oxidant, thereby ensuring the treatment effect of the exhaust gas and preventing the occurrence of air pollution.
