DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1In this embodiment, a special fume hood for finishing octanoylglycine includes a fume hood body 1, two layers of mesh plates 2 are fixed on the top between the inner walls on the four sides of the fume hood body 1, fans 3 are fixed on the left and right ends of the inner bottom wall of the fume hood body 1, air inlet holes 4 are opened on the left and right sides of the fume hood body 1, and the inner cavity of the air inlet hole 4 is provided with a filter 5, and the upper and lower ends of the inner cavity of the left and right side walls of the fume hood body 1 are provided with replacement mechanisms 6 for facilitating the replacement of the filter 5, and the inner top wall of the bottom inner cavity of the fume hood body 1 is provided with a moving mechanism 7 for facilitating the movement of the fume hood body 1.

[0023] Among them, support seats are fixed on the left and right ends of the lower surface of the fume hood body 1, fans are fixed on the left and right ends of the lower surface of the mesh plate 2 placed at the lower end, and air guide covers are fixed on the opposite sides of the left and right side walls of the inner cavity of the fume hood body 1, and the air inlet end of the fan 3 is connected to the air guide cover.

[0024] It can be understood that capryloyl glycine is placed on the mesh plate 2, and then the fan 3 is started. The air inlet end of the fan 3 draws air in through the air inlet hole 4. The air is filtered when passing through the filter 5, and then enters the inner cavity of the air guide cover, and finally dispersed through the air outlet end of the fan 3. The fan is then used to blow the drawn air upward, so that the inner cavity of the fume hood body 1 can be ventilated.

[0025] See also Figure 2-3 In order to prevent octanoylglycine from being contaminated by dust, the replacement mechanism 6 in this embodiment includes a cavity 601 opened at the upper and lower ends of the inner cavity of the left and right side walls of the fume hood body 1, and the left end between the opposite sides of the inner cavity of the front and rear side walls of the cavity 601 is rotatably connected to a rotating rod 602 through a bearing, and a worm gear 603 is fixed to the outer surface of the rotating rod 602, and a driven bevel gear 604 is fixed to the outer surface of the rotating rod 602 and located in front of the worm gear 603. One side of the driven bevel gear 604 is meshed with a driving bevel gear 605, so that the driving bevel gear 605 rotates, and the rotation of the driving bevel gear 605 causes the driven bevel gear meshed and connected to one side thereof. 604 rotates, and the rotation of the driven bevel gear 604 drives the rotating rod 602 to rotate. The rotation of the rotating rod 602 causes the worm wheel 603 to rotate. One side of the worm wheel 603 is meshedly connected with a worm 606. Limit plates 607 are fixed on the opposite sides of the worm 606 at the upper and lower ends. The upper surface of the limit plate 607 passes through the air inlet hole 4 and extends to the inner cavity of the air inlet hole 4. The rotation of the worm wheel 603 causes the worm 606 to move. At this time, the two worms 606 move in opposite directions on the outer surface of the limit rod. The movement of the worm 606 drives the limit plate 607 to move until one end of the limit plate 607 releases the restriction on the filter 5, and the filter 5 can be removed and replaced.

[0026] Among them, the inner cavities of the two active bevel gears 605 are fixed with driving rods, and the opposite sides of the two driving rods penetrate the fume hood body 1 and extend to the side away from the fume hood body 1. The inner walls of the upper and lower ends of the cavities 601 on the opposite sides are fixed with limiting rods, and the worm 606 makes up and down linear motion on the outer surface of the limiting rod. The cross-sectional shape of the limiting plate 607 is U-shaped, and the size of the inner cavity of the limiting plate 607 is adapted to the size of the filter 5.

[0027] It should be noted that, by regularly replacing the filter 5 through the replacement mechanism 6, not only the filtering effect of the filter 5 is improved, but also dust can be prevented from entering the inner cavity of the fan 3 to cause contamination of the capryloyl glycine.

[0028] See also Figure 4 In order to move the fume hood body 1, the moving mechanism 7 in this embodiment includes a motor 701 fixed to the top wall of the inner cavity at the bottom of the fume hood body 1, and the output shaft of the motor 701 is fixed with a threaded rod 702, and the outer surface of the threaded rod 702 is threadedly connected with a moving plate 703. When the motor 701 is started, the output shaft of the motor 701 rotates, thereby driving the threaded rod 702 to rotate. The rotation of the threaded rod 702 causes the moving plate 703 threadedly connected to its surface to move downward. Universal wheels 704 are fixed to the left and right ends of the lower surface of the moving plate 703. The moving plate 703 moves downward and drives the universal wheel 704 to move downward, so that the universal wheel 704 can contact the ground through the outlet, and then the fume hood body 1 can be pushed to move to a suitable position.

[0029] Among them, slide grooves are opened on the opposite sides of the left and right side walls of the bottom inner cavity of the fume hood body 1, and sliders are fixed on the left and right sides of the movable plate 703. The sliders make linear up and down movements in the inner cavity of the slide groove. When the movable plate 703 moves, the sliders fixed on both sides move in the inner cavity of the slide groove, which can limit the movement of the movable plate 703. The left and right ends of the inner bottom wall of the fume hood body 1 are opened with outlets that are compatible with the size of the universal wheel 704.

[0030] The working principle of the above embodiment is:

[0031] (1) When replacing the filter screen 5, first rotate the driving rod. The rotation of the driving rod rotates the active bevel gear 605. The rotation of the active bevel gear 605 rotates the driven bevel gear 604 meshingly connected to one side thereof. The rotation of the driven bevel gear 604 drives the rotating rod 602 to rotate. The rotation of the rotating rod 602 rotates the worm gear 603. The rotation of the worm gear 603 moves the worm 606. At this time, the two worm gears 606 move in opposite directions on the outer surface of the limit rod. The movement of the worm gear 606 drives the limit plate 607 to move until one end of the limit plate 607 releases the restriction on the filter screen 5. Then, the filter screen 5 can be removed and replaced.

[0032] (2) In order to facilitate the staff to move the fume hood body 1, the motor 701 is first started, and the output shaft of the motor 701 rotates, thereby driving the threaded rod 702 to rotate. The rotation of the threaded rod 702 causes the movable plate 703 threadedly connected to its surface to move downward. When the movable plate 703 moves, the sliders fixed on both sides of it move in the inner cavity of the slide groove, which can limit the movement of the movable plate 703. The movable plate 703 moves downward and drives the universal wheel 704 to move downward, so that the universal wheel 704 can contact the ground through the outlet, and then the fume hood body 1 can be pushed to move to a suitable position.
