Technical Field

[0001] The utility model relates to the field of feed additive production, in particular to an exhaust gas treatment device after feed additive production. Background Technique

[0002] During the production process of feed additives, exhaust gas containing dust, volatile organic compounds (VOCs), malodorous gases, etc. will be generated. If these exhaust gases are not treated, they will have an adverse impact on the environment and the health of employees. Therefore, the exhaust gas treatment device is an indispensable part of the feed additive production process.

[0003] In the existing exhaust gas treatment device for feed additive production, usually spray washing liquid is used to remove harmful gases with acidity, alkalinity or easy solubility in water through the washing effect, and then the exhaust gas passes through activated carbon to adsorb organic pollutants and malodorous gases. However, since the activated carbon is static in the adsorber, it is inconvenient to fully contact with the exhaust gas, and the speed of the exhaust gas passing through the activated carbon is relatively fast, so it is easy to have the situation that the exhaust gas treatment is incomplete.

[0004] Therefore, an exhaust gas treatment device after feed additive production has now been developed, which can stir the activated carbon, and at the same time extend the residence time of the exhaust gas in the activated carbon to ensure complete exhaust gas treatment. Content of the Utility Model

[0006] An exhaust gas treatment device after feed additive production includes a housing, a sponge board, a water pump, a circulation pipe, a spray pipe and an adsorption mechanism. The inner side of the lower part of the housing is connected with a sponge board, the lower side of the housing is connected with a water pump, the right side of the water pump is connected with a circulation pipe, the upper part of the circulation pipe is connected with the housing, the upper part inside the housing is connected with a spray pipe, the circulation pipe is connected with the spray pipe, and an adsorption mechanism capable of adsorbing harmful substances in the exhaust gas is arranged on the housing.

[0010] Further explanation: A filter screen is provided on the lower side of the inner box.

[0011] Further explanation: It further includes a vibration mechanism. The vibration mechanism includes a slide bar, a second spring, a toothed rod, and a toothed disc. The slide bar is slidably connected between the front and rear parts of the outer box. Second springs are connected between both the front and rear parts of the slide bar and the outer box.

Detailed implementation manners

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] An exhaust gas treatment device after the production of a feed additive, as Figure 1 and Figure 2 shown, includes an outer shell 1, a sponge plate 2, a water pump 3, a circulation pipe 4, a spray pipe 5 and an adsorption mechanism 6. A sponge plate 2 is connected to the inner side of the lower part of the outer shell 1. An air inlet pipe is provided on the left side of the lower part of the outer shell 1 for facilitating the passage of exhaust gas. A water pump 3 is connected to the lower side of the outer shell 1. A circulation pipe 4 is connected to the right side of the water pump 3. The upper part of the circulation pipe 4 is connected to the outer shell 1. A spray pipe 5 is connected to the upper part inside the outer shell 1. The spray pipe 5 is of a disc structure for facilitating the uniform spraying of the washing liquid. The circulation pipe 4 is connected to the spray pipe 5. An adsorption mechanism 6 is provided on the outer shell 1.

[0022] As Figure 1 , Figure 3 and Figure 4 shown, the adsorption mechanism 6 includes an outer box 61, a bidirectional motor 62, a lever 63, a first spring 64, a gear set 65, a cover plate 66, an inner box 67 and a stirring frame 68. The outer box 61 is connected to the upper side of the outer shell 1. The bidirectional motor 62 is connected to the front side of the outer box 61. A lever 63 is connected to the output shaft on the front side of the bidirectional motor 62. The cover plate 66 is slidably connected to the upper part of the outer box 61. The lever 63 is in pressing fit with the cover plate 66. A first spring 64 is connected between the cover plate 66 and the outer box 61. The stirring frame 68 is rotatably connected to the inside of the outer box 61. A gear set 65 is connected between the stirring frame 68 and the output shaft on the rear side of the bidirectional motor 62. The inner box 67 is slidably connected to the inside of the outer box 61. A filter screen is provided on the lower side of the inner box 67 for facilitating the adsorption of exhaust gas by activated carbon. The stirring frame 68 is located inside the inner box 67.

[0023] When using the present utility model, first place the outer shell 1 in the exhaust gas emission area of the feed additive production. Add the washing liquid into the outer shell 1, and then connect the exhaust gas discharge pipe with the intake pipe so that the exhaust gas enters the outer shell 1. After that, start the water pump 3 to pump the washing liquid into the circulation pipe 4, so that the washing liquid sprays from the spray pipe 5 into the exhaust gas to wash the exhaust gas. After the washing liquid sprays out, the impurities in the washing liquid are filtered by the sponge plate 2, so that the washing liquid is pumped back into the circulation pipe 4 for spraying. Activated carbon is added into the inner box 67. After the exhaust gas is sprayed, it flows upward into the outer box 61. The exhaust gas passes through the filter screen, so that the activated carbon adsorbs the pollutants and malodorous gases in the exhaust gas. When the activated carbon adsorbs, start the bidirectional motor 62 to drive the lever 63 to rotate, so that the lever 63 presses the cover plate 66. Through the action of the first spring 64, the cover plate 66 moves back and forth, so that the cover plate 66 controls the intermittent opening and closing of the outer box 61. When the outer box 61 is opened, the treated exhaust gas is discharged. At the same time when the bidirectional motor 62 is started, it drives the gear set 65 to engage and move, so that the stirring frame 68 rotates in the activated carbon, thus playing a role in being able to stir the activated carbon, and at the same time extending the residence time of the exhaust gas in the activated carbon to ensure complete exhaust gas treatment.

[0024] As Figure 1 and Figure 5 shown, it further includes a vibration mechanism 7. The vibration mechanism 7 includes a slide bar 71, a second spring 72, a toothed rod 73 and a toothed disk 74. The slide bar 71 is slidably connected between the front and rear parts of the outer box 61. Both the front and rear parts of the slide bar 71 are connected with the outer box 61 by the second spring 72. The slide bar 71 is connected with the inner box 67. The upper part of the inner box 67 is connected with the toothed rod 73. The output shaft on the front side of the bidirectional motor 62 is connected with the toothed disk 74. The toothed disk 74 is located in front of the lever 63, and the toothed disk 74 is in pressing cooperation with the toothed rod 73.

[0025] By using the vibration mechanism 7 of the present device, the activated carbon in the inner box 67 can be vibrated. When the bidirectional motor 62 is started, it drives the toothed disk 74 to rotate, so that the toothed disk 74 moves the toothed rod 73, causing the inner box 67 and the slide bar 71 to move. After the teeth on the toothed disk 74 disengage from the toothed rod 73, the inner box 67 and the slide bar 71 are reset by the action of the second spring 72, thus playing a role in being able to vibrate the activated carbon in the inner box 67 and increasing the contact area between the activated carbon and the exhaust gas.
