Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon boxes, in particular to an activated carbon box. Background Art

[0002] The activated carbon adsorption box is an environmentally friendly mechanical product that filters waste gas and absorbs odors. This equipment is an adsorption device for purifying high-concentration organic waste gas and paint waste gas. It uses the high-intensity adsorption force of activated carbon itself and combines it with the action of the fan to adsorb organic waste gas molecules. When the waste gas is powered by the centrifugal fan, the negative pressure enters the adsorption box and then enters the activated carbon adsorption layer, which has a very good adsorption effect on the waste gas of organic solutions.

[0003] Most of the existing activated carbon boxes introduce air from the inlet section, which flows out from the adsorption layer through direct current and is discharged from the outlet section. Due to the direct current, most of the air is adsorbed and filtered through the adsorption layer in the middle. The effect of the adsorption layers on both sides is lower, and it will be wasted when they are replaced.

[0004] In view of the above, the present application proposes an activated carbon box solution, which can perform diversion processing after the air is introduced, so that the air flows to the filter layers at different positions for filtering. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an activated carbon box, which solves the problems raised in the above background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] An activated carbon box includes a front axle, a middle axle and a rear axle;

[0008] The front shaft is trapezoidal and is used to introduce air that needs to be processed;

[0009] The central axis is in the shape of a rectangular parallelepiped, and its two ends are respectively connected to the front axis and the rear end;

[0010] The rear axle is in a trapezoidal shape and is used to discharge clean air after being adsorbed by activated carbon;

[0011] Wherein, the central axis comprises a bearing shell, a fixing frame, an adsorption layer and a fixing plate;

[0013] The adsorption layer is arranged in the fixing frame;

[0014] The fixing plates are connected to the bearing shells by bolts.

[0015] Optionally, the fixing frame includes a U-shaped frame, three front baffles and two rear baffles;

[0016] The U-shaped frame is adapted to be inserted into the bearing shell;

[0017] The three front baffles are distributed at one end of the U-shaped frame facing the front axle, so that the front side of the fixing frame has two air inlets;

[0019] Optionally, the front axle is connected to the middle axle, and the edge of the inner cavity of the front axle is pressed against the side of the fixing frame facing the front axle.

[0020] Optionally, the rear axle is connected to the middle axle, and the edge of the inner cavity of the rear axle is pressed against the side of the fixing frame facing the rear axle.

[0022] 1. Through the coordinated setting between the fixed frame and the adsorption layer, it is possible to promote the diversion of the introduced air when it flows to the central axis, so that multiple adsorption layers can all play an adsorption effect, reducing the probability of the adsorption layer at the edge contacting the air due to the direct flow of the introduced air, and the filtering effect is not high; this setting can increase the joint work between multiple adsorption layers and increase the adsorption effect.

[0027] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments.

[0028] In the description of the present invention, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "up", "down", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "end", "head" and "tail" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] The present application proposes an activated carbon box, which is specifically as follows:

[0030] For reference Figure 1 The present application is composed of a front axle 1, a middle axle 2 and a rear axle 3 which are connected and installed in sequence. The air to be treated is introduced through the front axle 1, and then adsorbed by the middle axle 2 in the middle, thereby discharging clean air treated by activated carbon adsorption from the rear axle 3.

[0031] For reference Figure 1 The front axis 1 is trapezoidal and connected with the middle axis 2. An opening is provided on its surface, and the air to be treated is introduced through the opening. Because of the connection with the middle axis 2, the air to be treated will immediately enter the middle axis 2 for treatment after being introduced.

[0032] For reference Figure 1-2 The middle axis 2 is specifically used for processing and filtering air, and it includes a bearing shell 21, a fixing frame 22, an adsorption layer 23 and a fixing plate 24; the bearing shell 21 plays a bearing role and promotes the front and rear ends to be connected with the front axle 1 and the rear axle 3, and its fixing frame 22 is provided with a plurality of groups of equidistant plug-in in the solid bearing shell 21, and the fixing frame 22 contacts the front axle 1 and the rear axle 3 on both sides after being inserted into the bearing shell 21, and because the front axle 1 and the rear axle 3 are thickened, the thickness is greater than the thickness of the bearing shell 21, so that after the front axle 1 and the rear axle 3 are connected to the bearing shell 21, a part will protrude outward, and this part presses against the left and right sides of the fixing frame 22 to prevent the fixing frame 22 from moving left and right, and secondly, in order to facilitate the disassembly and removal of the fixing frame 22, a fixing plate 24 is provided, and the fixing plate 24 is detachably provided on the bearing shell 21 by bolts, and is used to cover the fixing frame 22 inserted into the bearing shell 21.

[0033] Among them, the adsorption layer 23 plays the main adsorption effect on the central axis 2. The adsorption layer is an existing common activated carbon layer, which is composed of a large number of activated carbon particles or activated carbon blocks and a wrapping material; the wrapping material can be a structure suitable for carrying activated carbon particles or activated carbon blocks. After the adsorption layer 23 is prepared, the adsorption layer 23 can be inserted into the supporting shell 21.

[0034] For further reference Figure 3 In order to increase the effect of the adsorption layer 23 when doing the adsorption work, the fixing frame 22 is optimized again, and the fixing frame 22 is set to include three structures including a U-shaped frame 221, three front baffles 222 and two rear baffles 223; the U-shaped frame 221 is adapted to the inner cavity of the bearing shell 21 and inserted in the bearing shell 21, and the three front baffles 222 are distributed at the end of the U-shaped frame 221 facing the front axle 1, so that the front side of the fixing frame 22 has two air inlets; the two rear baffles 223 are distributed at the end of the U-shaped frame facing the rear axle 3, and correspond to the front and back of the two air inlets. Therefore, when the inhaled air enters from the two air inlets on the front side, it will cause the air to flow toward the adjacent adsorption layers 23 on both sides, and finally flow out from the port on the rear side where the rear baffle 223 is not set, and then be discharged from the rear axle 3 for filtration.

[0035] There are multiple groups of fixing frames 22, and the multiple groups of fixing frames 22 are not connected to each other, so as to reduce the possibility of the filtering effect being affected by the series connection between them.

[0036] Due to the design of the fixing frame 22, when the air flows, the air that needs to be adsorbed and filtered is directly discharged into the rear axle 3. Through the structural design of the fixing frame 22, the direct current air is disrupted, so that during the flow, it is not limited to flow in one direction, but can be diverted to both sides for adsorption and filtering effects.

[0037] In the utility model, the working steps of the device are as follows:

[0038] 1. First, prepare the adsorption layer 23 and firmly install it in the bearing shell 21 through the fixing plate 24;

[0039] 2. Secondly, the air to be treated is introduced through the front axle 1;

[0040] 3. Then, the air enters the central axis 2, passes through the fixed frame 22 for diversion, and then passes through the adsorption layer 23 for adsorption and filtration;

[0041] 4. Finally, the clean air treated with activated carbon adsorption is discharged through the rear axle 3, and the fixing plate 24 is removed regularly to replace the internal adsorption layer 23.

[0042] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
