Description

Technical Field

[0001] The utility model relates to the technical field of gas purification, and in particular to an irritating gas purification device for green printing. Background Art

[0002] Irritating gases are generated during printing. Irritating gases are a type of harmful gas that is irritating to the eyes, respiratory mucosa and skin. Inhalation of high concentrations of irritating gases can lead to acute respiratory failure, which is the most serious hazard caused by irritating gases and one of the common emergencies of occupational diseases. Common irritating gases include chlorine, ammonia, phosgene, nitrogen oxides, hydrogen fluoride, sulfur dioxide and sulfur trioxide. There are many kinds of irritating gas purification devices for green printing, but most of these purification devices are inconvenient to use, have low purification efficiency, cannot quickly complete the purification of irritating gases, and are inconvenient to replace purification tanks, which affects the purification effect and is not conducive to actual use.

[0003] After searching, the Chinese patent announcement number is CN215782294U, which discloses a irritating gas purification device for green printing. In this patent, by setting a purification component, the irritating gas can be effectively purified to avoid the harm of the irritating gas to the human body. By setting two fans, the purification efficiency of the irritating gas is improved, and the purification can be completed quickly. By setting an installation component, the replacement of the purification tank can be completed conveniently, thereby ensuring the purification effect of the irritating gas, which is beneficial to actual use;

[0004] However, when the above-mentioned device is in use, it can be seen from the accompanying drawings that the purification tank extracts and purifies the irritating gas through the first threaded tube and the second threaded tube before discharging it. Therefore, when replacing the purification tank, it is necessary to align the connection with the first threaded tube and the second threaded tube to avoid gas leakage during the purification process. However, there is no relevant structure in the above-mentioned device, which leads to the possibility of gas leakage after replacement, and the fixing method using multiple bolts makes subsequent disassembly and replacement cumbersome. In addition, when the irritating gas is sucked by the fan, other impurities are easily sucked in, which leads to a reduction in the service life of the purification component. Overall, the purification process is inefficient when the above-mentioned device is used. Utility Model Content

[0005] The utility model proposes an irritating gas purification device for green printing, which has the advantages of simple and quick replacement and installation of the filter structure, improved sealing at the joints of the structures, and prevention of impurities from entering the filter structure, thereby improving the working efficiency of the entire device. It solves the problems in the related art that the filter structure is cumbersome to disassemble and replace, the sealing between the filter structure and the upper and lower connecting structures is poor, and other impurities may be affected by the fan to enter the filter structure during operation, resulting in low working efficiency during the use of the entire device.

[0010] Preferably, the shape of the cross-section of the sealing plate is larger than the shape of the front surface of the filter element, and the rear edge of the sealing plate and the front edge of the filter block are both made of magnetic material. Therefore, when in use, after the filter element is installed, the sealing plate is used to block the front side of the installed filter block by utilizing the magnetic material on the side opposite to the filter block, thereby ensuring the sealing of the filter block.

[0011] Preferably, the right side of the air intake pipe is connected to the right side of the vehicle body, and the air intake pipe passes through the filter block and the right side of the vehicle body, so that when in use, the fan is started to draw the irritating gas in the space where the vehicle body is located into the inner cavity of the filter block through the air intake pipe.

[0014] The working principle and beneficial effects of the utility model are:

[0015] The irritating gas purification device for green printing uses a squeeze spring structure and a clamping block structure. When working, the elastic force of the squeeze spring is smaller than the elastic force of the torsion spring in the inner cavity of the torsion shaft used to connect the baffle plate and the groove, so that the filter element can be quickly installed. When disassembling, it can be moved out by using a large external force. The sealing performance between the mutual structures is improved by cooperating with the sealing plate and the air inlet pipe and the exhaust pipe directly connected to the filter block. At the same time, the rotatable cleaning strip and the cleaning brush are used to quickly clean the impurities on the surface of the filter plate, so as to achieve the effect of simple and fast replacement and installation of the filter structure, improve the sealing performance of the connection between the mutual structures, prevent impurities from entering the filter structure, and improve the working efficiency of the overall device.

At this time, the block 9 moves toward the inner cavity of the strip groove 7 and contracts the squeezing spring 8, which is convenient for the block 9 to pass through the baffle plate 5. The elastic force of the torsion spring makes it difficult for the installed block 9 and the filter element 6 to automatically move out of the inner cavity of the filter block 2. The position of the strip groove 7 matches the position of the groove 4. The block 9 is connected to the inner cavity of the strip groove 7 through the squeezing spring 8. The rear sides of the left and right blocks 9 facing the groove 4 are both arc-shaped. Therefore, when in use, the arc design on one side of the block 9 is used to facilitate the block 9 to contract into the inner cavity of the strip groove 7 and pass through the baffle plate 5. A sealing plate 10 is fixedly installed on the front side of the filter element 6. The shape of the cross section of the sealing plate 10 is larger than the shape of the front surface of the filter element 6. The rear edge of the sealing plate 10 is aligned with the front edge of the filter block 2. They are all made of magnet material, so when in use, after the filter element 6 is installed, the sealing plate 10 is used to block the front side of the installed filter block 2 by using the magnet material on the side opposite to the filter block 2, thereby ensuring the sealing of the filter block 2, and an air intake pipe 11 is fixedly installed on the right side of the filter block 2, and the right side of the air intake pipe 11 is connected to the right side of the vehicle body 1, and the air intake pipe 11 passes through and connects the filter block 2 and the right side of the vehicle body 1, so that when in use, the fan 12 is started to draw the irritating gas in the space where the vehicle body 1 is located into the inner cavity of the filter block 2 through the air intake pipe 11, the fan 12 is fixedly installed in the middle of the inner cavity of the air intake pipe 11, and a filter plate 13 is fixedly installed on the right side of the inner cavity of the air intake pipe 11, and the top of the exhaust pipe 3 extends out of the top of the vehicle body 1, and the filter plate 13 is arranged on the exhaust The top of the inner cavity of the tube 3, so that when in use, the filtered gas is discharged through the exhaust pipe 3, and the filter plate 13 is cooperated to prevent impurities from clogging the exhaust pipe 3. A placement block 14 is fixedly installed on the right side of the inner cavity of the vehicle body 1, and the placement block 14 is located at the top of the right side of the inner cavity of the vehicle body 1. A reserve filter element 6 is placed in the inner cavity of the placement block 14. A circular shaft 15 is movably installed on the right side of the vehicle body 1, a cleaning strip 16 is fixedly installed on the right side of the circular shaft 15, and a cleaning brush 17 is fixedly installed on the left side of the cleaning strip 16. The circular shaft 15 is located at the top of the position where the intake pipe 11 passes through the right side of the vehicle body 1, and the length of the part of the cleaning strip 16 located at the bottom of the circular shaft 15 is greater than the diameter of the inner cavity of the intake pipe 11, and the length of the cleaning brush 17 is greater than the distance between the cleaning strip 16 and the filter plate 13 on the right side of the inner cavity of the intake pipe 11.

[0025] Working principle: When working, first use the push handle on the left side of the vehicle body 1 to move the vehicle body 1 to a suitable use position, then start the fan 12, and use the fan 12 to draw air containing irritating gases into the inner cavity of the filter block 2 through the air inlet pipe 11, so that the gas is filtered by the filter element 6 and then discharged from the exhaust pipe 3. After a period of time, the filtering effect of the filter block 2 is reduced. At this time, the filter element 6 needs to be replaced, and then the vehicle body 1 is opened, and the sealing plate 10 is manually pulled forward to move the filter element 6 out of the inner cavity of the filter block 2. During the forward movement of the filter element 6, the elastic force of the torsion spring in the inner cavity of the torsion shaft connected with the baffle 5 and the groove 4 is greater than the elastic force of the extrusion spring 8. When the filter element 6 moves forward, a larger external force needs to be used to pass through the card The block 9 pushes the baffle plate 5 to rotate, so that the block 9 can be moved forward through the baffle plate 5, thereby allowing the filter element 6 to move out of the filter block 2, and then the spare filter element 6 placed in the inner cavity of the placement block 14 is taken to the inner cavity of the filter block 2, and the spare filter element 6 is pushed into the inner cavity of the filter block 2. During the forward installation of the spare filter element 6, the elastic force of the extrusion spring 8 is smaller than the elastic force of the torsion spring in the inner cavity of the torsion shaft, so that the block 9 contacts the baffle plate 5 and then contracts into the inner cavity of the strip groove 7, until after passing the baffle plate 5, the block 9 will automatically move out and reset under the elastic force of the extrusion spring 8 and extend into the inner cavity of the groove 4, so as to fix the installed filter element 6, and at the same time cooperate with the sealing plate 10 to seal the installed filter block 2 and the filter element 6;

[0026] During use, there may be more impurities on the surface of the filter plate 13 on the right side of the inner cavity of the intake pipe 11 due to the suction of air. Therefore, during use, the cleaning strip 16 is manually pushed to rotate, and the cleaning brush 17 is used to quickly clean the impurities on the surface of the filter plate 13 on the right side of the inner cavity of the intake pipe 11, so as to improve the working efficiency of the intake pipe 11.

[0027] In summary, compared with general similar devices, this irritating gas purification device for green printing has the advantages of simple and quick replacement and installation of the filter structure, improving the sealing of the joints between the structures and preventing impurities from entering the filter structure, thereby improving the working efficiency of the overall device.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
