[0040] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0041] Implementation Case 1

[0042] Please refer to Figure 1-13 As shown, a sulfur dioxide purification treatment device with automatic monitoring function includes a frame 1, a first box body 101 and a second box body 102 are welded to the top of the frame 1, an air intake pipe 103 is connected to the front bottom end of the second box body 102, a monitor 104 is installed on the top of the second box body 102, a probe of the monitor 104 extends to the inside of the second box body 102, and a blower 105 is arranged on the left top end of the second box body 102, an inclined plate 108 and an inclined platform 114 are fixedly connected to the inside of the second box body 102 on both sides, a first filter plate 109 is arranged on the top of the inclined platform 114, the bottom of the second box body 102 is connected to the first box body 101 through a through groove 110, and a lifting mechanism 2 and a purification mechanism 3 are also arranged on both sides of the inside of the second box body 102, an opening and closing mechanism 4 is installed on the bottom end of the inside of the second box body 102, a cleaning mechanism 5 is arranged on the top end of the inside of the first box body 101, and a driving mechanism 6 is installed on the back of the second box body 102.

[0043] In this solution, the gas to be purified enters the interior of the second box 102 through the air inlet pipe 103, and the lifting platform 207 is rapidly raised by the lifting mechanism 2, so that the gas to be purified also rapidly rises and passes through the first filter plate 109. The filter hole diameter of the first filter plate 109 is much larger than that of the second filter plate 407. The first filter plate 109 filters the large particles of smoke in the gas. Under the action of the hair dryer 105, the gas to be purified is blown to the right side of the interior of the second box 102, and the concentration of sulfur dioxide therein is monitored by the monitor 104. The sodium hydroxide solution is sprayed out by the purification mechanism 3 in a stirring state to process the sulfur dioxide therein, so that the sulfur dioxide generates sodium sulfite crystals and sodium bisulfite crystals, wherein these two crystals are soluble in water. If there are too many sodium sulfite crystals and sodium bisulfite crystals, they will cover the top of the second filter plate 407. An inclined first filter plate 109, an inclined platform 114 and an inclined plate 108 are provided so that small particles of smoke can also cover the top of the second filter plate 407. By the coordinated use of the opening and closing mechanism 4 and the cleaning mechanism 5, the top of the second filter plate 407 can be cleaned in time, so that small particles of smoke, sodium sulfite crystals and sodium bisulfite crystals can all fall on the inclined portion of the mounting member 111 for collection, and the fallen sodium hydroxide solution can be collected inside the first box body 101, so that some impurities are separated from the sodium hydroxide solution, which can shorten the subsequent recovery process of the sodium hydroxide solution to a certain extent, facilitate the secondary utilization of the sodium hydroxide solution, and meet the needs of the staff. It is worth mentioning here that the lifting mechanism 2, the purification mechanism 3 and the opening and closing mechanism 4 are all driven by the same driving mechanism 6, which is convenient and fast, relatively flexible, simple in structure and easy to use.

[0046] In this scheme, the working principle of the lifting mechanism 2 is as follows: the first gear 206 is rotated through the driving mechanism 6, and then the first rotating rod 204 and the second bevel gear 205 are rotated as a whole, so that the first bevel gear 203 and the first screw rod 201 are rotated as a whole, driving the lifting platform 207 and the punch rod 208 to move upward as a whole. On the one hand, the gas to be purified is squeezed upward, thereby accelerating the purification speed of sulfur dioxide gas. On the other hand, the position of the punch rod 208 also corresponds to the position of the filter holes of the first filter plate 109. The punch rod 208 can flush out impurities stuck in the filter holes of the first filter plate 109 upward, clear the first filter plate 109, and also meet the needs of the staff. The impurities flushed down have been mentioned in the above content and will also fall on the top of the second filter plate 407.

[0050] In this solution, the working principle of the purification mechanism 3 is as follows: the second gear 307 is rotated by the driving mechanism 6, and then the rotating shaft 305 and the active bevel gear 306 are rotated as a whole, so that the driven bevel gear 304, the second rotating rod 301 and the connecting rod 302 are rotated as a whole, and under the stirring rotation, the sodium hydroxide solution is sprayed out, and the sulfur dioxide gas is purified by a rapid reaction.

[0053] Please refer to Fig.10 As shown, mounting members 111 are fixedly installed on both sides of the first box body 101 , a fastening spring 112 is fixedly installed inside the vertical plate of the mounting member 111 , and the other end of the fastening spring 112 is fixedly connected to the abutment plate 113 .

[0054] In this embodiment, the working principle of the opening and closing mechanism 4 is as follows: the third gear 402 is rotated through the driving mechanism 6, driving the two groups of fixed plates 403 to rotate, and then the first rotating member 404, the second rotating member 405 and the third rotating member 406 are all rotated synchronously, so that the two groups of second filter plates 407 approach or move away from each other. In the process of approaching or moving away, the two groups of second filter plates 407 are always at the same height, and in this process, due to the provision of a fastening spring 112, the top end of the abutment plate 113 is also always at the bottom end of the second filter plate 407.

[0055] Example 5

[0056] Please refer to Fig.10 and Fig.11 As shown, the cleaning mechanism 5 includes a second screw rod 502, a fixed rod 503, a frame 504 and a servo motor 507.

When the two groups of second filter plates 407 are away from each other and located at the top end inside the first box body 101, the second screw rod 502 is driven to rotate through the output end of the servo motor 507, so that the two groups of frames 504 are first moved closer to each other and move to the middle position inside the first box body 101. Secondly, the output end of the hydraulic rod 505 extends and drives the scraper 506 to move downward, so that the bottom end of the scraper 506 is attached to the top end of the second filter plate 407, and then the output end of the servo motor 507 rotates in the opposite direction, driving the two groups of frames 504 and the scraper 506 to move away from each other as a whole, and cleaning the impurities on the two groups of second filter plates 407 to the inclined portion of the mounting member 111 for collection.

[0060] Please refer to Figure 7 and Figure 8 As shown, a third screw rod 612 is rotatably connected at the middle position inside the second mounting groove 611, and a lifting plate 614 is threadedly connected to the outer surface of the third screw rod 612. A guide rail 613 is also fixedly installed inside the second mounting groove 611, and the lifting plate 614 is slidably connected to the guide rail 613. A stepper motor 618 is installed on the top of the fixing member 601, and the top end of the third screw rod 612 is fixedly connected to the output end of the stepper motor 618. The outer side of the lifting plate 614 is fixedly connected to the second tooth plate 617 through the second connecting member 616, and the second tooth plate 617 is meshed with the first gear 206. An electric push rod 615 is also fixedly installed on the outer side of the lifting plate 614.

[0061] Please refer to Fig. 9As shown, slide grooves 619 are further provided on both sides of the first installation groove 602 , and sliders 620 adapted to the slide grooves 619 are fixedly installed on both sides of the lifting member 604 , and the sliders 620 are slidably connected to the inside of the slide grooves 619 .

[0062] In this solution, the working principle of the driving mechanism 6 is as follows: Figure 7 The state in is the state when the first spring 603 is not deformed. When the purification mechanism 3 needs to work, the output end of the electric push rod 615 is extended to press the switch 621, and the water pump 107 is started, so that the sodium hydroxide solution in the storage box 106 enters the second rotating rod 301, and the output end of the stepping motor 618 drives the third screw rod 612 to rotate, and then the lifting plate 614 moves upward, and the electric push rod 615 also moves upward, and drags the bottom of the first wedge block 607, and drives the lifting member 604 to move upward together, and the first A spring 603 is in a contracted state, and the lifting member 604 moves upward, driving the first connecting member 609 and the first tooth plate 610 to move upward as a whole, so that the second gear 307 rotates, thereby rotating the second rotating rod 301, so that the sodium hydroxide solution and sulfur dioxide react more fully under the stirring state, and the output end of the electric push rod 615 retracts and does not contact the switch 621, so that the water pump 107 stops working, thereby controlling the amount of sodium hydroxide solution sprayed according to the concentration of sulfur dioxide monitored by the monitor 104;

[0063] If the inclined surface of the first wedge block 607 contacts the inclined surface of the second wedge block 608 during the upward movement of the first wedge block 607, the telescopic rod 605 and the second spring 606 will be driven to shrink as a whole, so that the first wedge block 607 shrinks into the interior of the lifting member 604, and the lifting member 604 moves downward quickly to reset under the action of the first spring 603 restoring the deformation;

[0064] When the lifting mechanism 2 needs to work, the output end of the electric push rod 615 retracts, and the output end of the stepping motor 618 rotates in the opposite direction, so that the lifting plate 614 moves downward, driving the second gear plate 617 to move downward, and then the first gear 206 rotates, so that the lifting mechanism 2 works;

[0065] When the opening and closing mechanism 4 needs to work, with the cooperation of the electric push rod 615 and the stepper motor 618, the output end of the electric push rod 615 is in an extended state and is located on the top of the lifting member 604. Then, under the action of the output end of the stepper motor 618, the lifting plate 614 and the electric push rod 615 move downward as a whole, pulling the lifting member 604 downward, and the first spring 603 is in a stretched state, causing the first tooth plate 610 to move downward, which will drive the third gear 402 to rotate, thereby the opening and closing mechanism 4 works.

[0066] Working principle and use process of this device: In this scheme, the gas to be purified enters the interior of the second box 102 through the air inlet pipe 103, and the lifting platform 207 is rapidly raised by the lifting mechanism 2, so that the gas to be purified also rises rapidly and passes through the first filter plate 109. The filter hole diameter of the first filter plate 109 is much larger than that of the second filter plate 407. The first filter plate 109 filters the large particles of smoke in the gas. Under the action of the blower 105, the gas to be purified is blown to the right side of the interior of the second box 102, and the concentration of sulfur dioxide therein is monitored by the monitor 104, and the sodium hydroxide solution is sprayed out by the purification mechanism 3 in a stirring state to treat the sulfur dioxide therein, so that the sulfur dioxide generates sodium sulfite crystals and sodium bisulfite crystals, wherein these two crystals are soluble in water. If there are too many sodium sulfite crystals and sodium bisulfite crystals, they will cover the top of the second filter plate 407. Due to the inclined first filter plate 109, the inclined platform 114 and the inclined plate 108, small particles of smoke will also cover the top of the second filter plate 407. Through the coordinated use of the opening and closing mechanism 4 and the cleaning mechanism 5, the top of the second filter plate 407 can be cleaned in time, so that small particles of smoke, sodium sulfite crystals and sodium bisulfite crystals will all fall on the inclined portion of the mounting member 111 for collection, and the fallen sodium hydroxide solution will be collected in the first box 101. In this way, some impurities are separated from the sodium hydroxide solution, which can shorten the subsequent recovery and processing process of the sodium hydroxide solution to a certain extent, facilitate the secondary utilization of the sodium hydroxide solution, and meet the needs of the staff.
