Description
Technical Field
[0001] This utility model relates to the field of gas filtration technology for non-woven fabric drying, and specifically to a gas spill prevention device. Background Technology
[0002] During the drying process of nonwoven fabric production, harmful gases and tar are generated along with the gases. Therefore, a filtration device is used during the production process to absorb the gases and prevent them from escaping into the outside world.
[0003] According to the publication number CN218608371U, a treatment device for waste gas from nonwoven fabric production is disclosed, which includes a machine body. The left and right side walls of the machine body are provided with sliding grooves. A slider is connected inside the left sliding groove, and a lifting component is provided inside the right sliding groove. A connecting rod is fixed to one side of the lifting component and the slider. A brush is fixed between the two connecting rods. A No. 2 bearing is fixed to the inner top wall and inner bottom wall of the machine body. A rotating column is fixed inside the No. 2 bearing at the top.
[0004] In the aforementioned patented technology, the gas is filtered through a filter drum during use. This filtration method can only filter particles in the gas.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0033] The present invention will be further described below with reference to the embodiments.
[0034] Example 1: Please refer to the accompanying drawings in the instruction manual. Figure 1 and Figure 2 A gas spill prevention device includes a filter device 1, a filter device 2, a filter device 3, a filter device 4, a cleaning mechanism 5, and a driving mechanism 6. The filter device 1 is installed at the top center of the filter device 4. The filter device 2 and the filter device 3 are respectively installed on the top of the filter device 4 and on both sides of the filter device 1. The filter device 2 and the filter device 3 are both connected to the filter device 1. The cleaning mechanism 5 and the driving mechanism 6 are both installed on the filter device 1.
[0035] The filtration device 1 includes a separation box 11, a drain pipe 12 sealed to the bottom wall of the separation box 11, a filter cylinder 13 fixedly installed on the bottom wall of the separation box 11 corresponding to the drain pipe 12, and a connecting pipe 14 sealed to the bottom wall of the separation box 11. The outer wall of the filter cylinder 13 has a filter hole. The end of the connecting pipe 14 away from the separation box 11 is sealed to the outer wall of the drain pipe 12. Two sets of solenoid valves are installed on the drain pipe 12.
[0036] Filter device 4 includes a filter housing 41, and a separation box 11 is mounted on the top wall of the filter housing 41 via multiple support plates. The filter housing 41 and the separation box 11 are connected by a drain pipe 12. Filter device 2 includes a spray tower 21 fixedly mounted on the top wall of the filter housing 41. A conveying pipe 22 is sealed to the bottom outer wall of the spray tower 21, and a conveying pipe 23 is sealed to the top of the spray tower 21. The conveying pipe 22 can be connected to a non-woven fabric dryer via an external pipe, and the end of the conveying pipe 23 away from the spray tower 21 is sealed to the outer wall of the filter cylinder 13. A set of solenoid valves is installed at the connection between the bottom of the drain pipe 12 and the filter housing 41, and another set of solenoid valves is installed at the connection between the top of the drain pipe 12 and the separation box 11.
[0037] The filter device 3 includes an ion filter 31 fixedly installed on the top wall of the filter box 41. The outer wall of the ion filter 31 is sealed to the conveying pipe 33 and the conveying pipe 32. The end of the conveying pipe 33 away from the ion filter 31 is sealed to the outer wall of the discharge pipe 12. The outer wall of the conveying pipe 33 is equipped with a control valve. The conveying pipe 32 can be connected to an external pipe to a non-woven fabric dryer, so that the temperature of the filtered exhaust gas can be supplied to the dryer for recycling.
[0038] It is worth noting that both the spray tower 21 and the ion filter 31 are existing technologies. The solution sprayed out of the spray tower 21 causes the tar in the gas to settle to the bottom of the spray tower 21. The filter cartridge 13 is used to filter small solid particles in the gas. The ion filter 31 is specifically used to filter volatile organic substances in the gas.
[0039] In practical use, the gas generated by the dryer is discharged into the spray tower 21 through the first conveying pipe 22 to initially separate the tar in the gas. The separated gas then enters the filter cartridge 13 through the second conveying pipe 23 for secondary filtration. While the gas is being filtered in the filter cartridge 13, the two sets of solenoid valves on the discharge pipe 12 are closed, and the control valve on the fourth conveying pipe 33 is opened. The gas can only enter the fourth conveying pipe 33 through the discharge pipe 12 via the inside of the connecting pipe 14. Then, it enters the ion filter 31 through the fourth conveying pipe 33. The ion filter 31 can filter volatile organic substances. Through three filtrations, the filtration effect is improved. In addition, the filtered gas is discharged through the third conveying pipe 32 and then enters the drying device through the external pipe to provide a heat source and realize the recycling of energy.
[0040] Example 2: Based on Example 1, please refer to the accompanying drawings in the specification. Figure 1 - Figure 6 The cleaning mechanism 5 includes a connecting sleeve 51 rotatably mounted on the top wall of the separation box 11, a reciprocating screw 57 slidably mounted inside the connecting sleeve 51 and threadedly connected to the top wall of the separation box 11, a cleaning plate 54 fixedly mounted on the bottom wall of the reciprocating screw 57 and located inside the filter cylinder 13, a heater 53 fixedly mounted on the outer wall of the separation box 11, and a drain pipe 52 sealed and connected to the outlet end of the heater 53. The reciprocating screw 57 is a hollow cylinder, and the arc surface of the cleaning plate 54 and the inner surface of the filter cylinder 13... The cleaning plate 54 and the filter cylinder 13 are aligned on a straight line. The outer wall of the non-arc surface of the cleaning plate 54 is provided with water spray holes. The interior of the cleaning plate 54 is a hollow structure. The interior of the cleaning plate 54 and the interior of the reciprocating screw 57 are interconnected. The end of the drain pipe 52 away from the heater 53 is rotatably connected to the top of the connecting sleeve 51 through a rotary joint. The outer wall of the reciprocating screw 57 is fixedly installed on the limit block 55. The inner wall of the connecting sleeve 51 is provided with a limit groove 56 that slides with the limit block 55.
[0041] The filtration device 4 also includes a storage box 42 fixedly installed on the left side wall of the filter housing 41, a motor 43 fixedly installed on the front side wall of the storage box 42, two rotating rollers 44 respectively rotatably installed inside the right side of the filter housing 41 and inside the storage box 42, and a water conveying mechanism 47 set on the filter housing 41. The two rotating rollers 44 are connected by a conveyor belt assembly 46. The output end of the motor 43 is fixedly connected to the rotating roller 44 on the left side. A through groove 45 is opened at the top of the left side wall of the filter housing 41. The conveyor belt assembly 46 moves through the inside of the through groove 45. Multiple through filter holes are opened on the outer wall of the conveyor belt assembly 46.
[0042] The water supply mechanism 47 includes a water pump 471 fixedly installed on the front wall of the filter box 41, a water pump 472 sealed to the input end of the water pump 471, and a water supply pipe 473 sealed to the output end of the water pump 471. The end of the water pump 472 away from the water pump 471 is sealed to the front wall of the filter box 41, and the end of the water supply pipe 473 away from the water pump 471 is sealed to the water inlet of the heater 53.
[0043] The drive mechanism 6 includes a mounting plate 61 fixedly installed on the top wall of the separation box 11, a motor 62 fixedly installed on the top wall of the mounting plate 61, and a rotating rod 63 with its two ends rotatably installed on the inner top surface of the mounting plate 61 and the top wall of the separation box 11, respectively. The top of the rotating rod 63 is fixedly connected to the output end of the motor 62. Pulleys are fixedly sleeved on both the connecting sleeve 51 and the outer wall of the rotating rod 63. The two pulleys are connected by a transmission belt 64.
[0044] In practical use, by turning on motor 62, rotating rod 63 starts to rotate. Under the action of transmission belt 64, connecting sleeve 51 starts to rotate. Under the limit of limit block 55 by limit groove 56, reciprocating screw 57 starts to rotate. At the same time, due to the threaded connection between reciprocating screw 57 and the top wall of separation box 11, reciprocating screw 57 carries cleaning plate 54 up and down inside filter cylinder 13. The arc surface of cleaning plate 54 cleans the inner wall of filter cylinder 13. At the same time, water pump 471 and water pipe 472 can draw out water from inside filter box 41 and discharge it into heater 53 through water pipe 473. The heated water enters the interior of heater 53 through the top of reciprocating screw 57 and is finally discharged from the interior of cleaning plate 54 through water spray hole, rinsing the inner wall of filter cylinder 13 and improving the cleaning effect. Moreover, the heated water is more likely to remove tar. At the same time, the centrifugal force generated by the rotation of cleaning plate 54 can increase the force of water impacting the inner wall of filter cylinder 13 and improve the cleaning effect.
[0045] During the rinsing process, the two sets of solenoid valves on the drain pipe 12 can be opened, and the control valve on the conveyor pipe 33 can be closed. At this time, the water-liquid mixture inside the separator 11 will enter the interior of the filter box 41 through the drain pipe 12. The mixture will fall onto the conveyor belt assembly 46, which will filter the mixture. The filtered water can enter the bottom of the filter box 41 cavity through the filter hole 2, which can realize the recycling of water and reduce resource consumption. At the same time, the drive motor 43 is started. With the cooperation of the two rotating rollers 44, the conveyor belt assembly 46 can discharge the filtered particles through the channel 45 into the interior of the storage box 42 for storage, which is convenient for subsequent processing.
[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
