During the sample preparation process using the U-shaped frame circulating sampling device, the exterior of the device is directly exposed to the experimental environment. Once harmful gases are released from the U-shaped frame circulating sampling device, it is difficult to effectively remove the harmful gases between the device and the experimenters. At the same time, the device is difficult for the experimenters to adjust the angle.

[0004] In view of this, a catalyst sample preparation fume hood was designed to solve the above problems. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a catalyst sample preparation ventilation cabinet.

[0020] Example 1: Combination Figures 1 to 4 As shown, the present invention provides a catalyst sample preparation fume hood, including a support assembly 100, a cabinet adjustment assembly 200 mounted on the support assembly 100, and a fume hood assembly 300 mounted on the cabinet adjustment assembly 200. The support assembly 100 provides a support carrier for the cabinet adjustment assembly 200, the cabinet adjustment assembly 200 provides a rotation carrier for the fume hood assembly 300, and the fume hood assembly 300 provides a sealed protection for the U-shaped frame circulating sampling device.

[0021] The support assembly 100 includes a load-bearing base plate 110, a rotating base 120 in the middle of the load-bearing base plate 110, and four clips 130 arranged in a cross shape on the top of the load-bearing base plate 110. The clips 130 have two oval holes inside, and bolts 140 are inserted into the oval holes. The bolts 140 are threaded into the load-bearing base plate 110. The cabinet adjustment assembly 200 includes a track plate 210 movably installed outside the auxiliary rotation base 120, a pre-installed pad 2101 fixedly installed inside the track plate 210, a bottom support plate 240 fixedly installed outside the pre-installed pad 2101, a support plate 220 fixedly installed on the top of the track plate 210, a horizontally placed double-acting screw 230 threaded inside the support plate 220, and a baffle 250 installed outside the track plate 210. The fume hood assembly 300 includes a housing 310 movably mounted outside the track plate 210, a back plate 350 fixedly mounted on the back of the housing 310, a fan 330 fixedly mounted inside the housing 310, a sealing pad 340 fixedly mounted on the bottom of the outer end of the fan 330, a limit plate 3301 and a rack 3302 respectively mounted on both sides of the fan 330, a chassis 320 mounted outside the housing 310, a motor 3201 fixedly mounted inside the chassis 320, a gear 3202 mounted on the motor 3201, and the gear 3202 is adapted to mesh with the rack 3302.

[0022] When in use, the load-bearing base plate 110 is installed on the workbench in advance, and four clips 130 are evenly fixed on the top of the load-bearing base plate 110 using multiple bolts 140 until the four clips 130 are distributed in a cross shape. Then the track plate 210 is movably installed on the outside of the auxiliary rotation base 120. By rotating the outer wheel of the bidirectional lead screw 230, as the bidirectional lead screw 230 moves laterally outward along the inside of the support plate 220, the inner end of the bidirectional lead screw 230 will drive the back plate 350 and the outer shell 310 to slide outward along the track plate 210 until the pre-installed pad 2101 and the bottom support plate 240 are exposed. Then, the U-shaped frame circulating sampling device is assembled in the pre-installed pad 2101. According to the experimental personnel's position requirements, the exposed port of the outer shell 310 can be changed by manually rotating the track plate 210. When the motor 3201 runs and cooperates with the gear 3202 to push the rack 3302 and the fan 330 to descend, the bottom end of the sealing pad 340 will press against the top of the bottom support plate 240. At this time, the U-shaped frame circulating sampling device will be in a closed environment to achieve safe and continuous sample preparation.

[0023] Example 2: Combination Figure 4 As shown, in the above embodiment, a crossbar 3501 is installed on the inner side of the back plate 350, and a scraper pad 360 is installed on the outer side of the crossbar 3501, and the scraper pad 360 has a structure that is wider at the top and narrower at the bottom. Rectangular slots are provided on both sides of the outer casing 310, and a glass plate 3101 is fixedly installed in the rectangular slots; The inner wall of the outer casing 310 is fixedly installed with symmetrically distributed horizontal plates, and the bottom support plate 240 is adapted to be inserted into two adjacent horizontal plates. The bottom of the fan 330 is provided with an air intake slot, and the inner side of the top of the fan 330 is provided with an exhaust slot.

[0024] Preferably, the baffle 250 is located inside the scraper pad 360 and is used to limit the lateral movement of the back plate 350 and the outer shell 310. The outer shell 310 has two symmetrically distributed vertical slots inside. The limiting plate 3301 and the rack 3302 are respectively movably installed in the two vertical slots. The motor 3201, which is operated through the cloud, will drive the rack 3302 and the fan 330 to adjust the height, so as to facilitate the venting of harmful gases released by the U-shaped frame circulating sampling device at different flow rates, and at the same time, it is convenient for the experimental personnel to observe.

[0025] The working principle and usage process of this utility model are as follows: The load-bearing base plate 110 is pre-installed on the workbench. Then, four clips 130 are fixedly installed on the top of the load-bearing base plate 110 using multiple bolts 140 until the four clips 130 are arranged in a cross shape. Then, the track plate 210 is movably installed on the outside of the auxiliary rotating base 120. The pre-installed pad 2101 and the track plate 210 are snapped between two of the clips 130. Then, the bidirectional screw 230 is rotated until the bidirectional screw 230 extends outward along the support plate 220. Finally, the bidirectional screw 230 will drive the back plate 350 and the outer shell 310 to move laterally along the track plate 210. The pre-installed pad 2101 and the bottom support plate 240 will be exposed. Then, the U-shaped frame circulating sampling device is installed in the pre-installed pad 2101. During real-time sample preparation of the catalyst using the U-shaped frame circulating sampling device, the back plate 350, outer shell 310, and fan 330 covering the U-shaped frame circulating sampling device provide an effective ventilation environment for the sample preparation area. As the motor 3201 starts and runs, the motor 3201, in conjunction with the gear 3202, drives the rack 3302 and the fan 330 to descend as a whole until the bottom end of the sealing pad 340 fits against the top of the base plate 240. At this time, the U-shaped frame circulating sampling device can perform anti-interference sample preparation in a sealed environment. To meet the requirements of the working angle, the cabinet adjustment component 200 and the fume hood component 300 can rotate along the auxiliary rotating base 120.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
