Description

Technical Field

[0001] This application relates to the field of dyeing and printing waste gas treatment equipment, and in particular to a dyeing and printing waste gas treatment device with a filtration mechanism. Background Technology

[0002] Dyeing and printing waste gas refers to harmful gases generated during the dyeing and printing process, mainly originating from pretreatment, dyeing, printing, cleaning, and equipment maintenance. These waste gases typically contain various pollutants, which pose certain hazards to the environment and human health. They are usually treated using waste gas treatment devices.

[0003] Waste gas treatment devices typically include a pretreatment system, a spray system, an adsorption system, and an emission system. The waste gas passes through filters and other devices in the pretreatment system to remove impurities, then undergoes spray treatment in the spray system to reduce harmful substances, and then passes through adsorbents such as activated carbon in the adsorption system to adsorb harmful substances. Finally, it is discharged through the emission system.

[0004] The exhaust gas contains impurities such as lint, which can easily clog the filter screen after prolonged use. Usually, the filter screen needs to be removed and cleaned, which is inconvenient. Utility Model Content

[0005] To address the inconvenience of cleaning after removing the filter screen, this application provides a dyeing and printing waste gas treatment device with a filtration mechanism.

[0006] The dyeing and printing waste gas treatment device with a filtration mechanism provided in this application adopts the following technical solution:

[0007] A dyeing and printing waste gas treatment device with a filtration mechanism includes a treatment box and a filter box. A spray assembly is installed inside the treatment box, and an exhaust pipe is installed on the treatment box. The treatment box and the filter box are connected by a pipeline. An air inlet pipe is installed on the side of the filter box away from the treatment box. A filtration mechanism is installed inside the filter box, and the filtration mechanism includes a filter plate. An air suction assembly is installed inside the filter box. The air suction assembly includes an air suction pipe for suctioning lint from the filter plate and an air suction mechanism for providing negative pressure to the air suction pipe. The air suction pipe is distributed along the length of the filter plate, and an air suction nozzle is installed on the side of the air suction pipe facing the filter plate. The air suction mechanism is installed on the filter box and connected to the air suction pipe through an air outlet pipe. A lifting mechanism for driving the air suction pipe to move up and down is installed inside the filter box.

[0008] By adopting the above technical solution, the exhaust gas enters the filter box through the air inlet pipe, is filtered by the filter plate, and is then transported to the treatment box by the pipeline. It is then sprayed by the spraying mechanism and discharged through the exhaust pipe. When the filter plate needs to be cleaned after a period of use, the suction mechanism draws air into the suction pipe, and at the same time, the lifting mechanism drives the suction pipe to move up and down. At this time, the suction pipe sucks away the lint on the filter plate through the suction nozzle on one side, making the filter cleaning operation convenient.

[0009] Optionally, the lifting mechanism includes a motor and a screw. The screw is rotatably installed inside the filter box and is distributed parallel to the filter plate. The motor is mounted on the filter box, and the screw is connected to the output shaft of the motor. A slider is slidably installed inside the filter box. The slider slides in a direction perpendicular to the suction pipe. The slider is threadedly connected to the screw, and one end of the suction pipe is connected to the slider.

[0010] By adopting the above technical solution, the motor drives the screw to rotate, the screw drives the slider to slide, and at this time the slider drives the suction pipe to move up and down, adsorbing the lint on the filter plate. The suction pipe has a large coverage area on the filter plate.

[0011] Optionally, the suction mechanism includes a suction fan and a duct. The duct is located at one end of the outlet pipe away from the suction pipe, and the suction fan is located at one end of the duct away from the suction pipe. The duct is equipped with a sieve plate for filtering lint, and the sieve plate is detachably connected to the duct.

[0012] By adopting the above technical solution, the suction fan draws air into the suction pipe through the outlet pipe, and the lint is drawn to the air duct and collected by the sieve plate, making the lint collection operation convenient.

[0013] Optionally, the slider is provided with a brush plate, which is distributed along the length of the suction pipe. The brush plate has bristles on the side facing the filter plate, and one end of the bristles is in contact with one side of the filter plate.

[0014] By adopting the above technical solution, when the slider moves the suction pipe, the bristles on the brush plate brush off the lint on the filter plate and suck it away through the suction nozzle on the suction pipe, which has a good cleaning effect on the lint.

[0015] Optionally, the filter box is provided with a rotating rod, which is connected to the screw via a belt drive. The rotating rod is provided with a striking mechanism for intermittently striking one side of the filter plate.

[0016] By adopting the above technical solution, when the screw rotates, it drives the rotating rod to rotate, and the rotating rod drives the striking mechanism to strike the filter plate, shaking off the lint and other impurities on the filter plate, further enhancing the cleaning effect on the filter plate. At the same time, the screw is driven synchronously, making the driving operation convenient.

[0017] Optionally, the striking mechanism includes striking rods and a turntable. The turntable is coaxially connected to the rotating rod. Multiple striking rods are provided and evenly arranged along the circumferential sidewall of the turntable. One end of the striking rod abuts against one side of the filter plate.

[0018] By adopting the above technical solution, when the rotating rod rotates, it drives the turntable to rotate. When the turntable rotates, the striking rod on the turntable intermittently strikes one side of the filter plate, causing the filter plate to vibrate and resulting in a better cleaning effect.

[0019] Optionally, the turntable has a groove on its outer circumferential wall, the groove being distributed along the radius of the turntable, the striking rod being slidably installed in the groove of the turntable, and a spring being provided on the turntable in the groove, one end of the spring being connected to one side of the striking rod.

[0020] By adopting the above technical solution, when one end of the striking rod comes into contact with one side of the filter plate, the striking rod is pushed by the spring and the striking rod makes elastic impact on the filter plate, reducing the probability of the striking rod damaging the filter plate.

[0021] Optionally, a collection box is slidably installed at the bottom of the filter box and on the side of the filter plate facing the air intake pipe.

[0022] By adopting the above technical solution, some of the impurities shaken off during cleaning fall to the collection box on the lower side. The collection box can be slid out for cleaning, reducing the probability that impurities will be blown up again and re-attach to the filter plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the filter plate needs to be cleaned after a period of use, the suction mechanism draws air into the suction pipe, and at the same time the lifting mechanism drives the suction pipe to move up and down. At this time, the suction pipe sucks away the lint on the filter plate through the suction nozzle on one side, making the filter cleaning operation convenient.

[0025] 2. By setting a rotating rod to drive the turntable, which in turn drives the striking rod to vibrate the filter plate, the amount of impurities adhering to the filter plate is reduced;

[0026] 3. Some impurities are collected through the collection box, making cleaning easier. Attached Figure Description

At this time, the slider 24 drives the suction pipe 3 to move up and down, adsorbing the lint on the filter plate 22. The suction pipe 3 has a large coverage area on the filter plate 22.

[0038] Reference Figure 3A brush plate 241 is horizontally arranged on the slider 24. The brush plate 241 is distributed along the length of the suction pipe 3. There are two brush plates 241, which are located on the upper and lower sides of the suction pipe 3 respectively. The brush plate 241 has bristles on the side facing the filter plate 22. One end of the bristles is in contact with one side of the filter plate 22. The bristles are evenly arranged along the length of the brush plate 241. When the slider 24 moves the suction pipe 3, the bristles on the brush plate 241 brush off the lint on the filter plate 22 and suck it away through the suction nozzle 31 on the suction pipe 3.

When one end of the striking rod 61 abuts against one side of the filter plate 22, the striking rod 61 is pushed by the spring 63, and the striking rod 61 elastically strikes the filter plate 22, reducing the probability of the striking rod 61 damaging the filter plate 22.

[0043] Reference Figure 1 and Figure 2 A collection box 29 is slidably installed at the bottom of the filter box 2 and on the side of the filter plate 22 facing the suction pipe 3. During cleaning, some of the shaken-off impurities fall into the collection box 29 on the lower side. The collection box 29 is slid out for cleaning.

[0044] The implementation principle of the dyeing and printing waste gas treatment device with a filtration mechanism in this application embodiment is as follows: the waste gas enters the filter box 2 through the air inlet pipe 21, is filtered by the filter plate 22, and is transported to the treatment box 1 by the pipeline 13, is sprayed by the spray pipe 112, and is discharged through the exhaust pipe 12.

[0045] When the filter plate 22 needs to be cleaned after a period of use, the suction mechanism 4 draws air into the suction pipe 3, and at the same time, the motor 51 drives the suction pipe 3 to move up and down. At this time, the suction pipe 3 sucks away the lint on the filter plate 22 through the suction nozzle 31 on one side. At the same time, the rotating rod 27 drives the striking rod 61 on the turntable 62 to strike and vibrate the filter plate 22, shaking off the lint and other impurities on the filter plate 22, which are then collected in the collection box 29.
