Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a modular adsorption and concentration device. Background Art

[0002] Adsorption concentration devices can be used to capture and remove volatile organic compounds produced in industrial processes. After the exhaust gas passes through the device, VOCs will be adsorbed onto the adsorbent, thereby reducing emissions to the environment.

[0003] A Chinese patent discloses a waste gas adsorption and concentration device (authorization announcement number CN218687930U). The patented technology includes a mounting frame, an absorption mechanism and a mounting assembly. A fixed box is fixedly installed on the top of the mounting frame; the absorption mechanism is arranged on the inner side of the fixed box, and the absorption mechanism includes a fixed plate and a rotating rod. Two sets of fixed plates are fixedly installed on the inner side of the fixed box, and a rotating rod is rotatably installed between the two sets of fixed plates. The waste gas adsorption and concentration device can control the start of the motor to make the gear and the gear ring mesh and drive the mounting box, so that the zeolite rotates to absorb the waste gas, and the fanning plate rotates to fan the waste gas. The waste gas can be introduced into the fixed box through the air inlet pipe, so that the filter screen can roughly filter the waste gas, and the wire mesh, sponge and activated carbon can filter the fine impurities in the waste gas.

[0004] This patented technology purifies harmful substances in exhaust gas through activated carbon, but the activated carbon is fixedly installed inside the equipment. When the activated carbon adsorption is saturated and needs to be replaced, it is necessary not only to stop the operation of the equipment, but also to manually clean out the saturated activated carbon before adding new activated carbon. The replacement process is laborious and cumbersome. Therefore, those skilled in the art provide a modular adsorption concentration device to solve the problems raised in the above background technology. Utility Model Content

[0009] The adsorption structure includes a rotating shaft, a grid frame arranged in a circular array on the outer wall of the rotating shaft, a filter box inserted into the grid frame, a clamping plate at one end of the filter box, a spring located inside the side of the filter box, and a clamping block at one end of the spring;

[0010] as well as;

[0013] Specifically, when the grid plate and the clamping plate rotate, they fit tightly with the inside of the mounting shell to prevent gas from flowing out from the sides of the grid plate and the clamping plate, and the rotating shaft is rotatably supported inside the mounting shell through the bearing.

[0014] Furthermore, a card slot is provided on the inner wall of the installation frame, and the card block corresponds to the card slot;

[0015] Specifically, the card block is clamped in the card slot and is elastically supported and positioned by a spring.

[0016] Furthermore, a fixing plug is provided at the opening of one end of the filter box, and a gripping groove is provided inside the upper end of the card plate;

[0017] Specifically, the fixed plug seals the opening position at one end of the filter box.

[0018] Furthermore, the inner wall of the grid tube is provided with symmetrically distributed guide rails, and the outer wall of the filter box is provided with symmetrically distributed sliders that are slidably sleeved on the outer wall of the guide rails;

[0022] 2. Beneficial effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] The utility model contains activated carbon in a filter box and supports it through a grid frame, which is distributed in an annular shape on the inner wall of the installation shell. The support frame and the inner wall of the installation shell are rotatably installed. After the gas is input into the installation shell, it can flow to both sides above, and the activated carbon can adsorb harmful substances in the exhaust gas, thereby improving the exhaust gas purification amount. When the activated carbon near the air inlet of the installation shell is used for a period of time and its adsorption capacity decreases, the grid frame at the upper end is adjusted to both sides above the air inlet by rotating the rotating shaft, thereby ensuring the exhaust gas adsorption effect. Multiple activated carbon modules and multiple purifications can improve the purification effect.

[0025] At the same time, because the adsorption structure is connected to the installation frame through a card plate and is in the shape of multiple modules, when it is smoother, the card plate can be directly pulled out to drive the filter box to be moved out, and the saturated activated carbon can be replaced, avoiding the need to clean the saturated activated carbon in advance and the problem of shutdown operation affecting production. The modular adsorption structure is easy to use.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0041] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] See also Figure 1-Figure 4 As shown, this embodiment is a modular adsorption concentration device, including a main structure 100;

[0044] The main structure 100 includes a mounting shell 101, an air outlet 103 provided inside the upper end of the mounting shell 101, an air inlet 104 provided inside the lower end of the mounting shell 101, and a bracket 102 located at the lower end of the housing;

[0045] The adsorption structure 300 includes a rotating shaft 304, a grid frame 302 arranged in a circular array on the outer wall of the rotating shaft 304, a filter box 303 inserted into the grid frame 302, a clamping plate 301 at one end of the filter box 303, a spring 311 located inside the side of the filter box 303, and a clamping block 305 at one end of the spring 311;

[0046] The inner wall of the installation shell 101 is provided with a sealing sleeve, the front and rear ends of the grid frame 302 and one end of the clamping plate 301 are provided with arc surfaces, and the arc surfaces are in contact with the sealing sleeve, the front and rear ends of the installation shell 101 are embedded with bearings, and the front and rear ends of the rotating shaft 304 are rotatably inserted into the bearings;

[0047] The inner wall of the installation frame is provided with a card slot 310, and the card block 305 corresponds to the card slot 310;

[0048] A fixing plug 309 is provided at the opening of one end of the filter box 303, and a gripping groove 306 is provided inside the upper end of the clamping plate 301;

[0049] The inner wall of the grid tube is provided with symmetrically distributed guide rails 308, and the outer wall of the filter box 303 is provided with symmetrically distributed sliders 307 that are slidably sleeved on the outer wall of the guide rails 308;

[0050] Using the adsorption structure 300;

[0051] The mounting shell 101 is mounted through the bracket 102, and the air inlet 104 is connected to the exhaust gas delivery pipeline. The exhaust gas enters the mounting shell 101 through the air inlet 104, and the gas flows to both sides and upward, flows through the grid frame 302 and the filter box 303 and contacts the activated carbon, and the harmful gas in the exhaust gas is adsorbed and purified by the activated carbon;

[0052] After a period of use, the rotating shaft 304 drives the grid frame 302 to rotate, and the position of the grid frame 302 is adjusted. The grid frame 302 close to the air inlet 104 rotates to one side, or directly rotates to one side of the air outlet 103. The activated carbon at the bottom is saturated quickly, followed by the middle, and the top is the slowest. After the grid frame 302 rotates, the activated carbon with fast adsorption saturation rotates to one side, and the corresponding air inlet 104 with relatively good adsorption is avoided. The problem of too fast adsorption saturation of the activated carbon leads to a decrease in the exhaust gas purification effect of the activated carbon at the bottom;

[0053] The saturated activated carbon corresponds to the air outlet 103 and is pulled outward through the gripping groove 306. The card block 305 is squeezed and the squeezing spring 311 contracts, so that the filter box 303 is pulled to the outside and replaced directly with a new one. The filter box 303 is positioned by inserting the block into the card slot 310 to realize the modular replacement of the activated carbon. During the process of exhaust gas adsorption and concentration, the activated carbon can be easily replaced.

[0054] Example 2

[0055] See also Figure 1-Figure 4 As shown, this embodiment is based on the embodiment 1 and also includes:

[0056] as well as;

[0057] The fixing structure 200 includes a threaded sleeve 201 at the upper end of the bracket 102, a screw 204 rotatably inserted into the threaded sleeve 201, positioning grooves 206 opened on the outer wall of the rotating shaft 304 and distributed at equal intervals, and a positioning block 203 located at the upper end of the screw 204 and inserted into the positioning groove 206.

[0058] The outer wall of the screw rod 204 is sleeved with a torsion block 202, one end of the rotating shaft 304 is provided with a rotating rod 205, and the outer wall of the rotating rod 205 is provided with rotating rods 207 in a circular array;

[0059] Performing use of the fixed structure 200;

[0060] During the rotation of the shaft 304, the positioning block 203 disengages from the positioning groove 206, and the gripping rotating rod 207 applies force to the rotating rod 205, driving the shaft 304 to rotate, thereby causing the grid frame 302 on the outer wall of the shaft 304 to rotate. After the rotation, the rotating torsion block 202 drives the screw rod 204 to rotate in the opposite direction, and the screw rod 204 drives the upper positioning block 203 to be inserted into the positioning groove 206, so that the rotating shaft 304 is fixed, and the grid frame 302 after the fixed position remains stable during use.
