Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon adsorption tanks, in particular to an activated carbon adsorption tank with a filter element that is easy to replace. Background Art

[0002] Activated carbon is a specially treated carbon. Organic raw materials are heated in an airless environment to reduce non-carbon components. This reaction with gases erodes the surface, creating a well-developed microporous structure. Because the activation process is microscopic, with numerous molecular carbides eroding the surface in a pitting pattern, the activated carbon's surface possesses countless tiny pores, making it suitable for a variety of applications requiring impurity removal. However, after prolonged use, activated carbon requires prompt replacement to maintain its adsorption properties.

[0003] According to an activated carbon adsorption tank disclosed (Announcement No.: CN219209460U), in the above application, the exhaust gas can be adsorbed and purified by the coordinated use of the activated carbon adsorption tank, support legs, air guide cone, top cover, hydraulic rod, lifting block, right-angle plate, mounting net, activated carbon particle body, connecting column and movable plate. Compared with the traditional activated carbon adsorption tank, the activated carbon adsorption tank is convenient for replacing and disassembling the mounting net and the activated carbon particle body. On the one hand, it is convenient to repair the activated carbon adsorption tank and ensure the adsorption and purification effect of the activated carbon adsorption tank. On the other hand, it is convenient to recycle the activated carbon, effectively reducing the waste of resources. It is highly practical and easy to promote and use.

[0004] However, in actual use of the above equipment, the filter element is directly placed in the mounting plate. During long-term use, vibrations often occur. The vibrations can cause the activated carbon particles in the mounting plate to move, which can easily lead to inconsistent thickness of the activated carbon in the mounting plate, making the adsorption effect of the activated carbon on the waste material uneven. In view of this, we propose an activated carbon adsorption tank with an easy-to-replace filter element. Utility Model Content

[0011] Preferably, the distance between the upper splint and the lower splint is consistent with the thickness of the activated carbon board, and the diameter of the central opening of the fixed frame is consistent with the diameter of the activated carbon board. The activated carbon board can be placed in the center of the fixed frame, and the activated carbon board can be fixed between the upper splint and the lower splint by rotating the rotating rod.

[0012] Preferably, a limiting groove is provided on the outer wall of the fixed frame, the spring telescopic block is slidably connected to the inner wall of the limiting groove, and the extrusion block passes through the inner wall of the limiting groove and is slidably connected to the inner wall of the limiting groove, so that the extrusion block can slide in the limiting groove through the reset spring, causing the spring telescopic block to contract.

When the connecting plate drives the spring telescopic rod to move to the limit slot, the spring telescopic block extends and fits into the limit slot, fixing the rotation angle of the rotating rod so that the rotating rod will not rotate again, thereby improving the fixing effect of the fixing frame.

[0026] like Figures 1-6As shown, the utility model provides a technical solution: an activated carbon adsorption tank with an easy-to-replace filter element, comprising a tank body 1, an outer wall of the tank body 1 is fixedly connected to a fixed bracket 2, an outer wall of the tank body 1 is provided with a material port 3, an outer wall of the tank body 1 is hinged with a sealing door 4, an outer wall of the sealing door 4 is fixedly connected to a sealing gasket 5, an outer wall of the sealing door 4 is slidably connected to a locking rod 6, an inner wall of the tank body 1 is rotatably connected to a fixed frame 7, an inner wall of the fixed frame 7 is fitted with an activated carbon plate 8, a fixing assembly 9 is arranged inside the fixed frame 7, and the fixing assembly 9 comprises a rotating shaft 91, a rotating rod 92, an upper splint 93, a lower splint 94, a fixing plate 95, a bolt 96, a pressure plate 97 and a friction pad 98.

[0027] In one embodiment of the present utility model, the rotating shaft 91 is fixedly connected to the arc-shaped outer wall of the fixed frame 7, the planar outer wall of the fixed frame 7 is rotatably connected to the rotating rod 92, the upper end outer wall of the rotating rod 92 is fixedly connected to the upper splint 93, and the lower end of the rotating rod 92 is fixedly connected to the lower splint 94.

[0028] In one embodiment of the present utility model, the fixing plate 95 is fixedly connected to the upper outer wall of the rotating rod 92, and the outer walls of the fixing plate 95 and the upper clamping plate 93 are penetrated and threadedly connected with bolts 96, and the lower end of the bolt 96 is rotatably connected to the pressure plate 97, and the lower outer wall of the pressure plate 97 is provided with a friction pad 98.

[0029] In one embodiment of the present utility model, a limiting assembly 10 is provided inside the fixed frame 7, and the limiting assembly 10 includes a connecting plate 101, which is fixedly connected to the arc-shaped outer surface of the rotating rod 92, and the end of the connecting plate 101 away from the rotating rod 92 is slidably connected to a spring telescopic block 102.

[0030] In one embodiment of the present invention, the push plate 103 passes through and is slidably connected to the outer wall of the fixed frame 7. The end of the push plate 103 close to the rotating rod 92 is fixedly connected to the extrusion block 104, and the end of the extrusion block 104 away from the push plate 103 is fixedly connected to the return spring 105.

[0031] In addition, the distance between the upper clamping plate 93 and the lower clamping plate 94 is consistent with the thickness of the activated carbon board 8, and the diameter of the central opening of the fixing frame 7 is consistent with the diameter of the activated carbon board 8. The activated carbon board 8 can be placed in the center of the fixing frame 7, and then the rotating rod 92 is rotated to fix the activated carbon board 8 between the upper clamping plate 93 and the lower clamping plate 94, so that the activated carbon board 8 can be fixed to prevent the activated carbon board 8 from falling.

[0032] In an embodiment of the present utility model, a limiting groove is provided on the outer wall of the fixed frame 7, the spring expansion block 102 is slidably connected to the inner wall of the limiting groove, and the extrusion block 104 passes through the inner wall of the limiting groove and is slidably connected to the inner wall of the limiting groove, so that the extrusion block 104 can slide in the limiting groove through the reset spring 105, so that the spring expansion block 102 contracts, which can block the spring expansion block 102 from extending into the limiting groove. When the fixed frame 7 is pushed into the tank body 1, the push plate 103 drives the extrusion block 104 to leave the limiting groove, so that the spring expansion block 102 can extend into the limiting groove, fix the rotation angle of the rotating rod 92, and prevent the activated carbon plate 8 from falling.

[0033] In an embodiment of the present utility model, there are two groups of fixing components 9 and limiting components 10, and the two groups of fixing components 9 and limiting components 10 are mirror-distributed at both ends of the fixing frame 7, so that both ends of the activated carbon plate 8 can be fixed, so that the fixing effect of the fixing frame 7 on the activated carbon plate 8 is better.

[0034] In an embodiment of the present utility model, a sliding groove is provided on the inner wall of the fixed frame 7, and the upper splint 93 and the lower splint 94 are both slidably connected to the inner wall of the sliding groove. Rotating the rotating rod 92 can make the upper splint 93 and the lower splint 94 slide into the interior of the sliding groove, so that the activated carbon plate 8 can be placed inside the fixed frame 7.

[0035] In an embodiment of the present invention, the upper and lower ends of the rotating shaft 91 are rotatably connected to the inner wall of the tank body 1, and the outer wall of the fixed frame 7 is in contact with the inner wall of the tank body 1, so that the fixed frame 7 can be rotated to the outside of the tank body 1 through the rotating shaft 91, which is convenient for users to replace.

[0036] In the present invention, when the activated carbon plate 8 needs to be replaced, the sealing door 4 is opened, and the fixing frame 7 is rotated to make the fixing frame 7 leave the tank body 1. At this time, the bolts 96 can be loosened, and the rotating rod 92 can be rotated to remove the activated carbon plate 8. Then, a new activated carbon plate 8 is placed in the opening of the fixing frame 7. Then, the rotating rod 92 is rotated to fix the activated carbon plate 8 between the upper clamping plate 93 and the lower clamping plate 94. Then, the bolts 96 are tightened to move the bolts 96 and drive the pressing plate 97 to further fix the activated carbon plate 8. At the same time, the friction pad 98 on the pressing plate 97 can prevent the pressing plate 97 from being damaged. The carbon plate 8 is offset to make the adsorption effect of the activated carbon more uniform. When the rotating rod 92 is rotated, the connecting plate 101 drives the spring expansion block 102 to move above the limiting groove. At this time, the limiting groove is filled with the extrusion block 104, so that the spring expansion block 102 cannot extend. When the fixed frame 7 is pushed back into the tank body 1, the push plate 103 is squeezed, so that the extrusion block 104 leaves the limiting groove. At this time, the spring expansion block 102 extends and is stuck in the limiting groove, so that the rotation angle of the rotating rod 92 is fixed, so that the rotating rod 92 will not rotate again, which can prevent the activated carbon plate 8 from falling and make the fixing effect of the fixed frame 7 better.

[0037] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
