Description

Technical Field

[0001] This utility model relates to the field of activated carbon filtration and adsorption technology, specifically to a mobile activated carbon adsorption device. Background Technology

[0002] Activated carbon adsorption utilizes the high specific surface area and surface chemical properties of porous carbon materials to capture VOCs, odors, and particulate matter in waste gas through physical and chemical adsorption. Filter-type activated carbon adsorption devices employ modular housings integrating multiple layers of activated carbon filter media, delaying pore clogging and significantly improving adsorption efficiency compared to traditional adsorption methods. To provide strong support for industrial emergency environmental protection, a mobile filtration-type activated carbon adsorption device is needed.

[0003] According to the Chinese patent "An Activated Carbon Adsorption Filter Tower" authorized announcement number "CN222624100U", this utility model supports the activated carbon drawer box through two hollow horizontal plates at the ends of the plate frame. At the same time, the external plate can be pulled outward to drive the rollers to rub and roll in the guide groove of the plate frame, ensuring the smooth movement of the activated carbon drawer box. Meanwhile, the rails are embedded in the limiting groove of the activated carbon drawer box, which can ensure the stable horizontal movement of the activated carbon drawer box when it is pulled out, and prevent the activated carbon drawer box from tilting and falling when it is pulled out. This further assists the staff in disassembling and assembling the activated carbon drawer box and reduces the difficulty of disassembling and assembling the activated carbon drawer box.

[0004] Although the above application can make it easier for workers to dismantle the activated carbon by setting multiple activated carbon drawer boxes inside the activated carbon tower box, along with rollers, shelves and other components, thus facilitating the replacement of activated carbon, the activated carbon in this application is piled up inside the activated carbon drawer boxes during operation. This can easily lead to some of the effective adsorption areas of the activated carbon overlapping, preventing some of the activated carbon from being fully utilized and causing a decrease in overall adsorption efficiency.

[0005] Based on this, the present invention designs a mobile activated carbon adsorption device for filtration to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a mobile activated carbon adsorption device for filtration.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A mobile activated carbon adsorption filtration device includes a trolley and a carbon box, wherein the carbon box is fixedly connected to the upper surface of the trolley.

[0009] Furthermore, the flipping mechanism includes a flipping block disposed in the carbon box, with baffles fixedly connected to both bottom ends of the flipping block, the two baffles being slidably connected to the inner bottom wall of the carbon box, and an electric push rod disposed between the flipping block and the inner bottom wall of the carbon box.

[0010] Furthermore, the cross-section of the flipping block is an isosceles trapezoid, and the inclined surface of the flipping block is provided with multiple anti-slip textures.

[0011] Furthermore, the electric push rod is fixedly connected to the inner bottom wall of the carbon box, the drive end of the electric push rod is fixedly connected to the lower surface of the flipping block, and the baffle is inserted into the inner bottom wall of the carbon box and slidably connected to the inner bottom wall of the carbon box.

[0012] Furthermore, guide blocks are fixedly connected to both sides of the bottom wall of the carbon box. The cross-section of the guide block is a right trapezoid, and the two inclined surfaces of the guide block are arranged opposite each other.

[0013] Furthermore, a sliding plate is slidably connected to the inner wall of the guide block. The sliding plate is driven by a hydraulic rod and is parallel to the inclined surface of the guide block. A discharge channel is provided on the inner wall of the guide block, and the discharge channel connects the carbon box to the outside.

[0014] Furthermore, a filter box is installed above the trolley, which is connected to the inlet of the carbon box. Multiple filter screens are fixedly connected to the inner wall of the filter box, and the mesh size of the multiple filter screens decreases from the inlet to the outlet of the filter box.

[0015] Furthermore, a collection box is fixedly connected between the filter box and the surface of the trolley, the bottom of the filter box is connected to the collection box, and a drawer is provided inside the filter box.

[0016] Furthermore, a chimney is fixedly connected to the surface of the trolley, the chimney is connected to the outlet of the carbon box, and a fan is fixedly connected to the inner wall of the chimney, the fan being positioned above the connection between the chimney and the carbon box.

[0017] Beneficial effects

[0018] 1. By setting a turning mechanism inside the carbon box, the activated carbon accumulated in the carbon box can be turned intermittently. This can effectively turn the activated carbon that is in contact with each other, thereby exposing the surfaces of the activated carbon that cannot be adsorbed, increasing the adsorption area of ​​the activated carbon, thus increasing the adsorption capacity of the activated carbon for harmful gases. This allows the same volume of activated carbon to adsorb more harmful substances, improving the overall adsorption efficiency of the activated carbon.

[0019] 2. By installing a filter box in front of the carbon box inlet, harmful gases are purified in stages, preventing large particles, moisture, grease and other pollutants from directly contacting the activated carbon surface and preventing its pore structure from being blocked; by installing the filter box and carbon box on a trolley, the trolley's mobility allows for rapid arrival at emergency sites, effectively responding to sudden exhaust gas pollution.

[0028] 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.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A mobile activated carbon adsorption device for filtration includes a trolley 100 and a carbon box 300, with the carbon box 300 fixedly connected to the upper surface of the trolley 100.

[0031] The flipping mechanism 400 includes a flipping block 410 disposed in the carbon box 300. Both bottom ends of the flipping block 410 are fixedly connected to baffles 411. The two baffles 411 are slidably connected to the inner bottom wall of the carbon box 300. An electric push rod 412 is disposed between the flipping block 410 and the inner bottom wall of the carbon box 300.

[0032] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment of this utility model, the flipping block 410 has an isosceles trapezoidal cross-section, and the inclined surface of the flipping block 410 is provided with multiple anti-slip textures. The electric push rod 412 is fixedly connected to the inner bottom wall of the carbon box 300, and the driving end of the electric push rod 412 is fixedly connected to the lower surface of the flipping block 410. The baffle 411 is inserted into the inner bottom wall of the carbon box 300 and slidably connected to the inner bottom wall of the carbon box 300. Guide blocks 420 are fixedly connected to both sides of the inner bottom wall of the carbon box 300. The cross-section of the guide block 420 is a right trapezoid, and the two inclined surfaces of the guide block 420 are arranged opposite to each other. The inner wall of the guide block 420 is slidably connected to the slide plate 421, which is driven by a hydraulic rod. The slide plate 421 is parallel to the inclined surface of the guide block 420. The inner wall of the guide block 420 is provided with a discharge channel 422, which connects the carbon box 300 to the outside.

[0033] In this embodiment, the device is used in conjunction with a professional hazardous gas generating or storage equipment, so the interface of the device is compatible with the hazardous gas generating or storage equipment. The top of the carbon box 300 of the device is provided with an inlet for adding activated carbon, and the bottom sides of the carbon box 300 are provided with corresponding pull-out plates. The pull-out plates cooperate with the discharge channel 422. When it is necessary to replace the activated carbon, the hydraulic rod is first activated to drive the sliding plate 421 to retract into the guide plate, so that the discharge channel 422 is connected to the interior of the carbon box 300. The pull-out plates are opened and the electric push rod 412 is activated at the same time. The activated carbon is squeezed into the discharge channel 422 by the flipping block 410 and then slid out through the inclined surface of the discharge channel 422 for collection. The electric push rod 412 in the device has a periodic motion. The periodic motion of the electric push rod 412 is achieved by the forward and reverse rotation control of the electric motor. The rotational motion is converted into the linear reciprocating motion of the lead screw nut through the gear reduction box. By setting the periodic start / stop and direction switching parameters of the motor, regular extension and retraction movements can be generated. The periodic movement can effectively turn the activated carbon while reducing the probability of damage to the activated carbon caused by continuous turning. The carbon box 300 is connected to the filter box 200 and the chimney 500 through the conical shell, and a screen is set at the connection between the carbon box 300 and the conical shell to prevent activated carbon leakage. When adding activated carbon, an appropriate amount of activated carbon should be added to the carbon box 300 to avoid poor adsorption of harmful gases due to insufficient activated carbon and loss caused by friction between activated carbon during turning due to excessive activated carbon.

[0034] The flipping mechanism of this device is located inside the carbon box 300 and occupies part of the space in the carbon box 300. However, since the carbon box 300 does not need to be completely filled with activated carbon and the gas is in a flowing state when the activated carbon adsorbs harmful gases, and the internal space of the carbon box 300 is always in the gas flow path, it is only necessary to control the amount of activated carbon added to the carbon box 300 so that the gas passes through the surface of the activated carbon when it flows, so as not to affect the adsorption performance of the activated carbon. At the same time, since this device filters harmful gases, the flipping mechanism 400 will not affect the physical form and chemical properties of the harmful gases. Therefore, the flipping mechanism 400 will not have any negative impact on the filtration and purification of harmful gases.

[0035] In some embodiments, such as Figure 1 , Figure 2 and Figure 5As shown, in a preferred embodiment of this utility model, a filter box 200 is provided above the trolley 100. The filter box 200 is connected to the inlet of the carbon box 300. A plurality of filter screens 210 are fixedly connected to the inner wall of the filter box 200. The mesh size of the plurality of filter screens 210 decreases from the inlet to the outlet of the filter box 200. A collection box 220 is fixedly connected between the filter box 200 and the surface of the trolley 100. The bottom of the filter box 200 is connected to the collection box 220. A drawer 221 is provided inside the filter box 200. A chimney 500 is fixedly connected to the surface of the trolley 100. The chimney 500 is connected to the outlet of the carbon box 300. A fan 510 is fixedly connected to the inner wall of the chimney 500. The fan 510 is located above the connection between the chimney 500 and the carbon box 300.

[0036] In this embodiment, a sealing strip is required between the upper surface of the drawer 221 and the inner wall of the filter box 200 to keep the drawer 221 sealed with the filter box 200 when it is not pulled out, so as to prevent the leakage of harmful gases. At the same time, a limiting block is fixedly connected to the bottom of the filter 210 located in the middle of the multiple filter screens 210. A partition is provided in the middle of the drawer 221. The partition and the limiting block are used to isolate the filter area corresponding to each filter screen 210 in the filter box 200 to prevent the flow of impurities inside. The partition is inserted into the inner wall of the limiting block and the groove of the limiting block is set downward to reduce the probability of impurities accumulating in the groove.

[0037] When using this utility model, first add activated carbon into the carbon box 300, then push the trolley 100 next to the harmful gas equipment, then connect the inlet of the filter box 200 to the outlet of the harmful gas equipment and start the fan 510 and the electric push rod 412.

[0038] Once the hazardous gas equipment is stably connected to the filter box 200, the fan 510 blows air out through the chimney 500, making the overall internal air pressure of the device lower than the internal air pressure of the hazardous gas equipment. At this time, the hazardous gas will flow into the filter box 200 and enter the carbon box 300 after passing through the filter screen 210. When passing through the filter screen 210, the filter screen 210 will filter and intercept large particulate impurities in the gas and make them fall into the collection box 220 under the action of gravity.

[0039] Harmful gases entering the carbon box 300 are adsorbed by activated carbon. At this time, the electric push rod 412 periodically pushes the flipping block 410 up and down. When the flipping block 410 moves up and down, it will push the activated carbon in the carbon box 300 to flip. At the same time, the flipping of the activated carbon will accelerate the flow of gas in the carbon box 300, so that the harmful gases can fully contact the activated carbon. When the flipping block 410 moves upward, the baffle 411 will move with the flipping block 410 to prevent the activated carbon from falling below the flipping block 410 when the flipping block 410 moves upward. At the same time, the inclined surface of the flipping block 410 will push the activated carbon to both sides to the top of the guide block 420, and then fall down through the inclined surface of the guide block 420, thereby achieving the effect of flipping the activated carbon.

[0040] The purified gas enters the chimney 500 and is then blown out from the top of the chimney 500 by the fan 510.

[0041] It should be noted that the electric actuator 412, fan 510 and filter 210 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the electric actuator 412 and fan 510 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0042] 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. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
