Description

Technical Field

[0001] The utility model belongs to the technical field of adsorption towers, and in particular relates to an adsorption tower which is convenient for replacing activated carbon. Background Art

[0002] Activated carbon adsorption towers are a vital piece of equipment widely used in industrial waste gas treatment and air purification. They primarily utilize the adsorption properties of activated carbon to remove harmful substances from waste gas. Activated carbon, with its highly developed pore structure and large specific surface area, effectively absorbs pollutants such as various organic compounds, odors, and heavy metal ions. When waste gas containing pollutants passes through the activated carbon adsorption tower, the pollutants are adsorbed on the surface or in the pores of the activated carbon, thereby purifying the waste gas.

[0003] A public announcement (publication number): CN218794942U discloses an adsorption tower that facilitates the replacement of activated carbon. This technology discloses "comprising a tower body, a motor support plate fixedly connected to the front side of the tower body, a motor fixedly connected to the top of the motor support plate, a drive shaft fixedly connected to the output shaft of the motor, and three driven shafts rotatably connected to the inner wall of the front side of the tower body. This utility model has a reasonable structural design. By continuously rotating and striking the filter screen with a rubber hammer, the adsorption tower can be kept unobstructed for a long time, eliminating the need for manual handling and being easy to use. The activated carbon plate can be replaced by turning a handwheel and pulling the filter screen out of the tower body. This makes maintenance easy and worthy of widespread use."

[0004] However, in the aforementioned comparative documents, the activated carbon adsorption plate needs to be disassembled and replaced due to long-term use. During the replacement process, the sealing between the activated carbon adsorption plate and the tower body installation port is not good, and gas may leak from the installation port and the adsorption tower, which not only pollutes the environment but also threatens the health of operators. At the same time, it may be difficult to further stabilize the activated carbon plate after installation. After long-term use, the activated carbon may become loose, affecting its adsorption effect.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0026] The present invention provides an adsorption tower that facilitates the replacement of activated carbon. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0027] Reference Figure 1-4This embodiment provides a technical solution: an adsorption tower for facilitating replacement of activated carbon, comprising a tower body 1, an adsorption assembly 2 for adsorbing exhaust gas, and a sealing assembly 3 to prevent gas leakage. The adsorption assembly 2 is disposed inside the tower body 1, and the sealing assembly 3 is disposed on the front side of the tower body 1. The sealing assembly 3 is located between the tower body 1 and the adsorption assembly 2. Three groups of adsorption assemblies 2 are provided, and the three groups of adsorption assemblies 2 are disposed inside the tower body 1 in a linear array.

[0028] The sealing assembly 3 includes a sealing airbag 31 fixedly mounted on one side of the tower body 1. There are three sealing airbags 31, which correspond to the three groups of adsorption components 2 respectively. The top of the sealing airbag 31 is fixedly connected with a connecting pipe 32. The longitudinal section of the connecting pipe 32 is a mountain shape. The connecting pipe 32 is fixedly passed through the top of the tower body 1. The connecting pipe 32 is fixedly connected with an air intake pipe 33. The longitudinal section of the air intake pipe 33 is L-shaped. The bottom of the sealing airbag 31 is fixedly connected with an exhaust pipe 35. The exhaust pipe 35 is fixedly passed through the top of the tower body 1. Inside, one end of the exhaust pipe 35 is threadedly connected to a sealing plug 36. The sealing plug 36 is mainly made of rubber material and has a certain elasticity. After the adsorption component 2 is installed inside the tower body 1, the air flow flows through the air inlet pipe 33 and the connecting pipe 32 to the inside of the sealing airbag 31. The sealing airbag 31 then expands and contacts the adsorption component 2, thereby increasing the sealing between the adsorption component 2 and the tower body 1 and avoiding gas leakage. At the same time, the expanded sealing airbag 31 squeezes the closing plate 23, further increasing the stability of the installation of the adsorption component 2.

[0029] Reference Figure 2-3 An air pump 34 is fixedly connected to the top of the tower body 1 , and the air outlet of the air pump 34 is fixedly connected to the side of the air inlet pipe 33 away from the connecting pipe 32 . After the air pump 34 is running, the air flow is transmitted to the inside of the air inlet pipe 33 .

[0030] Reference Figure 2-4 The adsorption component 2 includes a frame 21 inside the tower body 1, and an activated carbon plate 22 is fixedly connected to the inner wall of the frame 21. A closing plate 23 is fixedly connected to one side of the activated carbon plate 22. The closing plate 23 is located at the center of one side of the frame 21. The inner circle of the sealing airbag 31 is tightly attached to the outer wall of the closing plate 23. The closing plate 23 drives the frame 21 to move to the inside of the tower body 1, so that the activated carbon plate 22 moves to a suitable installation position inside the tower body 1, and the activated carbon plate 22 filters and adsorbs the gas.

[0031] Reference Figure 3 The inside of the tower body 1 is fixedly connected with a card plate 4. The number of card plates 4 is equal to that of adsorption components 2 and they correspond one to one. The card plate 4 is slidably connected to the frame 21. The card plate 4 facilitates the movement of the frame 21 to the inside of the tower body 1.

[0032] Reference Figure 2-3A mounting groove 5 is provided on the front side of the tower body 1. The number of the mounting grooves 5 is equal to that of the adsorption components 2, and they correspond one to one. The closing plate 23 is fitted with the tower body 1 through the mounting groove 5. The sealing airbag 31 is installed on the front side of the tower body 1 through the mounting groove 5. The outer wall of the sealing airbag 31 is installed on the inner wall of the mounting groove 5. The mounting groove 5 facilitates the movement of the closing plate 23 to fit with the tower body 1.

[0033] Reference Figure 2 The closing plate 23 is threadedly connected with a self-tapping screw 24, which is threadedly connected to the tower body 1. The self-tapping screw 24 threads penetrate the corners of the closing plate 23 and extend to be threadedly connected to the tower body 1, thereby making the closing plate 23 firmly fixed on the front side of the tower body 1, so that the frame 21 can be detachably installed inside the tower body 1.

[0034] Reference Figure 2 A spring 25 is fixedly connected to the card plate 4, and one end of the spring 25 is fixedly connected to a rebound plate 26. The number of rebound plates 26 is equal to that of the card plate 4, and they correspond one to one. The rebound plate 26 is slidably connected to the card plate 4, and the rebound plate 26 is tightly attached to one side of the frame 21. After the tapping screw 24 moves to separate from the tower body 1, the spring 25 pushes the rebound plate 26 to move, so that the closing plate 23 is moved out from the inside of the mounting groove 5, thereby facilitating the removal of the activated carbon plate 22 from the inside of the tower body 1.

[0035] Working principle:

[0036] After the exhaust gas is transmitted to the interior of the tower body 1, it flows from left to right. The exhaust gas is sequentially adsorbed and filtered by the three adsorption components 2. The activated carbon plate 22 separates some impurities and odors in the exhaust gas. When the activated carbon plate 22 needs to be replaced, the tapping screw 24 rotates and moves to separate from the tower body 1, and the sealing plug 36 moves to separate from the exhaust pipe 35. The sealing airbag 31 changes from an expanded state to a contracted state, and the spring 25 changes from a compressed state to an initial state. The rebound plate 26 then pops out in a direction away from the spring 25, and the closing plate 23 moves to separate from the tower body 1, thereby removing the frame 21 from the interior of the card plate 4, so that the activated carbon plate 22 is removed from the interior of the tower body 1.

[0037] After the activated carbon plate 22 is installed inside the tower body 1, the self-tapping screws 24 fix the closing plate 23 and the tower body 1 together. When the self-tapping screws 24 are running, the gas is transmitted to the inside of the sealing airbag 31 through the air inlet pipe 33 and the connecting pipe 32. The connecting pipe 32 then expands and fits tightly against the closing plate 23, thereby increasing the sealing between the closing plate 23 and the tower body 1, avoiding gas leakage inside the tower body 1, and at the same time, the squeezing of the sealing airbag 31 further increases the stability of the installation of the closing plate 23.
