Description

Technical Field

[0001] The utility model relates to the technical field of ink production, in particular to an environmentally friendly ink reaction kettle fume treatment device. Background Art

[0002] The ink contains some gases that are harmful to the human body. The ink used mainly contains colorants, resins, solvents, auxiliary agents, etc. During the stirring reaction of the ink in the reactor, volatile organic waste gases such as benzene, toluene, xylene, butanone, lipids, ethers, etc. will be volatilized. Therefore, a large amount of organic waste gas will be discharged during the pressure relief and discharge of the reactor.

[0003] Existing reactors usually absorb and treat waste gas through the air suction equipment above the reactor. However, due to the certain distance between the air suction equipment and the reactor, some organic waste gas will still escape into the air during the pressure relief process of the reactor, causing environmental pollution.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides an environmentally friendly ink reaction kettle fume treatment device, such as Figures 1 to 4As shown, it includes a bracket 1, an exhaust gas treatment tank 2 and a first air suction hose 3 arranged on the exhaust gas treatment tank 2, a first support rod 4 is arranged on the top of the bracket 1 in the horizontal direction, the first support rod 4 is fixedly connected to the first air suction hose 3, the end of the first air suction hose 3 away from the bracket 1 is connected to the second air suction hose 5 in the vertical direction, the bottom end of the second air suction hose 5 is provided with an air suction hood 6, a second support rod 7 is movably arranged on the bracket 1 in the horizontal direction, the end of the second support rod 7 is fixedly connected to the air suction hood 6, and a driving mechanism 8 for driving the second support rod 7 to move in the vertical direction is arranged on the bracket 1.

[0027] Furthermore, the driving mechanism 8 includes a driving screw 8a vertically arranged on the bracket 1 and a driving block 8b cooperatedly arranged on the driving screw 8a. The bracket 1 is provided with a driving motor 9 for driving the driving screw 8a to rotate, and the second support rod 7 is fixedly connected to the driving block 8b.

[0028] Furthermore, a long strip-shaped limiting hole 10 is provided on the bracket 1 along the vertical direction, and two sides of the driving block 8 b are movably fitted in the limiting hole 10 .

[0029] Furthermore, the end of the second support rod 7 is rotatably disposed on the driving block 8b.

[0030] Furthermore, an end portion of the first support rod 4 is rotatably disposed on the bracket 1 .

[0031] Furthermore, a first telescopic block 11 is vertically provided at the bottom of the first support rod 4 , and a second telescopic block 12 is vertically provided at the top of the second support rod 7 . The top of the second telescopic block 12 is movably fitted to the inner wall of the first telescopic block 11 .

[0032] Furthermore, long first limiting blocks 13 are symmetrically arranged on both sides of the second telescopic block, and telescopic grooves 14 cooperating with the first limiting blocks 13 are symmetrically opened on the inner wall of the first telescopic block.

[0033] Furthermore, the air suction hood 6 is in the shape of a boss that is narrow at the top and wide at the bottom.

[0034] Furthermore, the bottom end of the air suction hood 6 is connected to an air suction portion 15 having a rectangular cross section.

[0035] Furthermore, the first air suction hose 3 and the second air suction hose 5 are both made of corrugated metal tubes.

[0036] During the reaction process of the reactor, there is a certain distance between the bottom of the suction hood 6 and the top of the reactor, so as to avoid affecting the feeding process of the reactor; after the reaction of the reactor is completed, the drive motor 9 is turned on to drive the driving screw 8a to rotate, driving the drive block 8b, the second support rod 7 and the suction hood 6 to descend to the rectangular suction part 15 to cover the top of the reactor, and then the reactor is opened to release the pressure, and the organic waste gas discharged from the top of the reactor is directly absorbed by the suction hood 6 in a negative pressure state and enters the waste gas treatment tank 2 for treatment (the waste treatment tank contains a vacuum pump that has been pumping air, an activated carbon adsorbent for treating organic waste gas, a photocatalyst, etc., which are prior art, so they are not described in detail and do not affect the actual technical scope of the present application); because the suction part 15 can cover the top of the reactor after the suction hood 6 descends, the organic waste gas discharged from the reactor will not escape into the air, thereby avoiding organic waste gas polluting the environment.

[0037] By providing a rotatable first support rod 4 and second support rod 7, the first support rod 4 and second support rod 7 can be rotated within a certain range, and the suction hood 6 can be aimed at other reactors, thereby achieving exhaust gas absorption and treatment of multiple reactors, expanding the usable range of the device, and reducing the equipment investment cost of the factory.

[0038] By setting the first telescopic block 11 and the second telescopic block 12, during the lifting and lowering of the second support rod 7, the second telescopic block 12 moves along the inner wall of the first telescopic block 11, which can not only improve the stability of the lifting and lowering process of the second air suction hose 5 driven by the second support rod 7, but also realize the synchronous rotation of the first support rod 4 and the second support rod 7.

[0039] By providing the first limiting block 13 and the telescopic slot 14 , the contact area between the first telescopic block 11 and the second telescopic block 12 is increased, and the stability of the second support rod 7 driving the second air suction hose 5 to rise and fall is further improved.

[0040] By setting a long strip-shaped limiting hole 10, the driving block 8b is raised and lowered along the limiting hole 10, which can not only increase the stability of the driving block 8b during the lifting process, but also limit the lifting range of the driving block 8b and the second support rod 7 by the length of the limiting hole 10, thereby avoiding excessive stretching or compression of the second suction hose 5.

[0041] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
