A circular slot is formed on the top of flange A, and a reinforcing screw is threaded onto the inner wall of the slot. One end of the reinforcing screw is threaded onto flange B. The top of flange B is movably connected to the bottom of flange A. A circular slot is also formed on the top of flange B, and an air inlet is movably connected to the inner wall of the slot. An air inlet pipe is fixedly connected to the bottom of the air inlet. This drying adsorption tower, through the arrangement of flange A, reinforcing screw, flange B, and air inlet, allows operators to fix the device using flanges A and B, and to secure them with the reinforcing screw. This improves the stability of the device, facilitates operation, and allows for quick installation or disassembly, increasing work efficiency.

[0004] This patent allows the fixing plate to be fixed with bolts, but the existing fixing method does not have a sealing effect, and leakage is likely to occur during use, thus affecting normal adsorption. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides a device for measuring the thickness of building floor slabs, including a drying tower body 1. A leak-proof component 2 is connected to the top of the drying tower body 1. The leak-proof component 2 includes a fixing plate 201, an air inlet 202 connected to the top of the fixing plate 201, a sealing groove 203 formed on the surface of the drying tower body 1, a sealing ring 204 disposed inside the sealing groove 203, six sets of extended bolts 205 circumferentially connected to the surface of the fixing plate 201, and four sets of support frames 206 circumferentially connected to the outer surface of the drying tower body 1. A threaded rod 207 is inserted into the rear end of each support frame 206, and bearings are connected to both ends of the threaded rod 207. 208 and throttle 209, the front end of bearing 208 is connected to moving block 210, both outer surfaces of moving block 210 are connected to slider 211, both inner walls of support frame 206 are provided with sliding groove 213, the bottom surface of moving block 210 is provided with groove 212, threaded rod 207 is threadedly connected to support frame 206, threaded rod 207 is rotatably connected to moving block 210 through bearing 208, the outer surface of slider 211 is in contact with the inner wall of sliding groove 213, slider 211 and sliding groove 213 are slidably connected, the size of groove 212 matches the size of the top of extension bolt 205.

[0024] The effect achieved in Embodiment 1 is that, when installing and fixing the fixing plate 201, the sealing ring 204 can be placed in the sealing groove 203 first, and then the fixing plate 201 can be placed on top of the drying tower body 1 and fixed with the extension bolt 205. Then, the handle 209 can be rotated forward, so that the handle 209 can drive the threaded rod 207 and the support frame 206 to rotate in the forward thread. In turn, the bearing 208 is driven by the thread rotation to move the moving block 210 forward. When the moving block 210 moves, it will also... The slider 211 slides within the groove 213, improving the stability of the moving block 210 during movement. This allows the moving block 210 to provide secondary fixation for the fixed plate 201. When the fixed plate 201 needs to be disassembled, all the extension bolts 205 can be removed first, and then the handle 209 can be reversed to allow the moving block 210 to retract into the support frame 206. At this point, the fixed plate 201 can be removed. This prevents leakage from the drying tower body 1, which could affect normal adsorption operation.

[0025] Example 2, as Figure 1 and Figure 4 As shown, a filter assembly 3 is installed inside the drying tower body 1. The filter assembly 3 includes a fixing frame 301. Limiting grooves 302 are opened on the inner walls of both sides of the fixing frame 301. A first filter screen 303 is installed inside the fixing frame 301. A second filter screen 304 is magnetically connected to the top of the first filter screen 303. A third filter screen 305 is magnetically connected to the top of the second filter screen 304. A fourth filter screen 306 is magnetically connected to the top of the third filter screen 305. Limiting blocks 307 are connected to both sides of the first filter screen 303, the second filter screen 304, the third filter screen 305 and the fourth filter screen 306.

[0026] The effect achieved in Embodiment 2 is that the fixing frame 301 is internally connected to a first filter 303, a second filter 304, a third filter 305, and a fourth filter 306, which can sequentially filter impurity particles of different sizes. The first filter 303 has a filtration efficiency of 99.7% for particles larger than one micrometer, ensuring that fine particles cannot pass through, further improving the purity of oxygen. At the same time, each filter is fixed by magnetic connection, which is convenient for disassembly. The design of the limiting block 307 and the limiting groove 302 can prevent the filter from shifting, thus improving the filtration effect.

[0027] Working principle: After fixing the fixed plate 201 with the extended bolt 205, the handle 209 can be rotated to move the moving block 210 forward and fix the fixed plate 201. The double fixing method of the extended bolt 205 and the moving block 210 improves the sealing effect of the drying tower body 1 and avoids leakage of the drying tower body 1, which would affect the normal adsorption. The first filter screen 303, the second filter screen 304, the third filter screen 305 and the fourth filter screen 306 can filter impurities of different sizes, further improving the purity of oxygen. They are also set to magnetic connection, which makes disassembly and cleaning very convenient.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
