Description

Technical Field

[0001] This application relates to the field of perchloric acid fume hoods, and more particularly to a dosing port structure for a perchloric acid fume hood and a perchloric acid fume hood. Background Technology

[0002] Perchloric acid fume hoods are laboratory equipment specifically designed for handling highly corrosive chemicals such as perchloric acid and hot nitric acid. They are primarily used in chemical analysis, research institutions, and industrial environments. The scrubbing tower inside the fume hood is mainly used to treat the acid mist generated during experiments. After initial spraying inside the fume hood, the exhaust gas enters the water scrubbing tower, where atomized water vapor dissolves the acidic substances. The gas then passes through a filtration layer before being discharged, ensuring that the exhaust gas meets emission standards. Since the internal scrubbing tower of the existing perchloric acid fume hood needs to be used for different experiments, different chemicals are required. In order to ensure that the effect of different chemicals is not affected, the dosing port needs to be cleaned. However, it is difficult to clean the dosing port directly on the scrubbing tower, which can easily lead to secondary pollution. Therefore, a perchloric acid fume hood with a dosing port structure that is easy to disassemble and replace is needed. Utility Model Content

[0003] To facilitate the disassembly and assembly of existing chemical dosing port structures, this application provides a chemical dosing port structure for a perchloric acid fume hood and a perchloric acid fume hood.

[0004] The present application provides a dosing port structure for a perchloric acid fume hood and a perchloric acid fume hood with the following technical solution: a dosing port structure for a perchloric acid fume hood and a perchloric acid fume hood, including a tower body disposed inside the perchloric acid fume hood and a dosing port and a dosing port mechanism disposed on the tower body; The dosing port mechanism includes a fixed sleeve plate fixedly fitted on the dosing port. Two fixed rings and two first housings are symmetrically fixedly installed on the cabinet. Corresponding fixed columns are fixedly installed inside each of the two first housings. Two sets of corresponding sliding blocks are slidably fitted on each of the two fixed columns. A corresponding L-shaped clamp is fixedly installed on one side of each of the two sets of sliding blocks. A corresponding spring is fitted on each of the two fixed columns. The two ends of the spring are respectively fixedly installed on the side of the sliding block and the first housing that are close to each other. The feed inlet and dosing inlet of the tower body are detachable, and the dosing inlet is located on the side of the tower body.

[0005] By adopting the above technical solution, the dosing port can be quickly disassembled and replaced, which facilitates deep cleaning of the disassembled dosing port and makes it easier to use next time. Therefore, the convenience and flexibility of disassembling and assembling the dosing port can be improved.

[0006] Preferably, the dosing port and the feed inlet on the side of the tower body are connected in a through-hole fixed connection.

[0007] By adopting the above technical solution, the dosing port and the feed port on the side of the tower are connected in a through-hole fixed connection, which can play an auxiliary role in installation and connection.

[0008] Preferably, the dosing port is configured as an L-shaped pipe.

[0009] By adopting the above technical solution, the dosing port is set as an L-shaped pipeline, which facilitates installation and use.

[0010] Preferably, each of the L-shaped clamps is fixedly installed with an installation ring on one side, and the two installation rings are connected to hooks by an external connecting rope, the hooks being adapted to the fixed rings.

[0011] By adopting the above technical solution and setting an installation ring, an auxiliary installation function can be achieved.

[0012] Preferably, the cabinet body has two symmetrical mounting slots, each containing a corresponding mounting block that is slidably installed. Both mounting blocks are fixedly installed to a fixing sleeve plate, and the sides of the two first housings that are close to each other are open. Each side of the fixing sleeve plate has a corresponding reinforcing slot, each containing a corresponding reinforcing block that is slidably installed. Both reinforcing blocks are fixedly installed to corresponding L-shaped clamps.

[0013] By adopting the above technical solution, rotating the knob will drive the worm gear to rotate, which in turn will drive the turbine and screw to rotate. The screw will cause the two connecting blocks to move closer together and then further apart, causing the two arc-shaped plates to move away from each other and engage with the clamping and fixing of the dosing port. This allows the dosing port to be disassembled. Then, by rotating the knob in the opposite direction, the dosing port can be installed and fixed. Therefore, the convenience and flexibility of cleaning, disassembly and replacement of the dosing port can be further improved.

[0014] Preferably, the dosing port mechanism further includes two second housings symmetrically fixedly installed on the cabinet. A screw is rotatably installed in one of the second housings. The screw has a bidirectional thread. Two connecting blocks are symmetrically screwed onto the screw. A corresponding arc-shaped plate is fixedly installed on one side of each of the two connecting blocks. A worm gear is fixedly installed at one end of the screw. A worm is adapted to the worm gear. A knob is fixedly installed at one end of the worm gear. A limit rod is fixedly installed in the other second housing. Two other connecting blocks are symmetrically slidably sleeved on the two limit rods. The other two connecting blocks are fixedly installed on the other side of the arc-shaped plate.

[0015] By adopting the above technical solution, the connecting block can be moved and positioned in a limited manner by setting a limiting rod.

[0016] Preferably, a support frame is fixedly mounted on one of the second housings, and one end of the worm gear is rotatably mounted on the support frame.

[0017] By adopting the above technical solution and setting up a support frame, the installation can be assisted.

[0018] Preferably, the two arc-shaped plates and the dosing port are clamped together.

[0019] By adopting the above technical solution, the curved plate and the dosing port are used for clamping, which facilitates clamping, installation and fixation.

[0020] Preferably, both of the arc-shaped plates are provided with anti-slip pads, the two second housings are open on the side that is close to each other, the cabinet is provided with an exhaust port and an air inlet, and one side of the cabinet is provided with an inspection door.

[0021] By adopting the above technical solution and setting anti-slip pads, the friction can be increased, thus further improving the stability and firmness of the installation and clamping.

[0022] This utility model also proposes a perchloric acid fume hood, which includes a dosing port structure for perchloric acid fume hood.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This application utilizes L-shaped clamps and the like. By pulling the two hooks away from each other, the two hooks move away from each other, causing the two L-shaped clamps to move closer together. This, in turn, causes the corresponding two sliding blocks to move, thereby compressing the corresponding springs. By releasing the two hooks, the dosing port can be quickly disassembled and replaced, facilitating deep cleaning of the disassembled dosing port and making it easier for the next use. Therefore, it can improve the convenience and flexibility of disassembling and assembling the dosing port.

[0024] 2. This application utilizes the cooperation of curved plates, etc., to rotate a knob, which in turn drives the worm gear to rotate. The rotation of the worm gear drives the turbine and screw to rotate. The rotation of the screw drives the two connecting blocks to move closer together, and the two connecting blocks to move further apart, causing the two curved plates to move further apart as well, thus clamping and fixing the dosing port. This allows the dosing port to be disassembled. Furthermore, by rotating the knob in the opposite direction, the dosing port can be installed and fixed. Therefore, the convenience and flexibility of cleaning, disassembly, and replacement of the dosing port can be further improved. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0027] This application discloses a dosing port structure for a perchloric acid fume hood and a perchloric acid fume hood. Example

[0028] Reference Figure 1 , Figure 5 and Figure 6 A dosing port structure for a perchloric acid fume hood and a perchloric acid fume hood, comprising a tower body 6 disposed inside the perchloric acid fume hood body 1 and a dosing port 2 and a dosing port mechanism disposed on the tower body 6; The feed inlet and dosing port 2 of the tower body 6 are detachable. The dosing port 2 is located on the side of the tower body 6. The dosing port 2 and the feed inlet on the side of the tower body 6 are connected in a through-hole fixed connection. The dosing port 2 is arranged in an L-shaped pipe. Reference Figure 2 , Figure 3 and Figure 4 The dosing port mechanism includes a fixed sleeve plate 11 fixedly sleeved on the dosing port 2. Two fixed rings 8 and two first housings 12 are symmetrically fixedly installed on the cabinet body 1. A corresponding fixed post 16 is fixedly installed inside each of the two first housings 12. Two sets of corresponding sliding blocks 15 are slidably sleeved on each of the two fixed posts 16. A corresponding L-shaped clamp 7 is fixedly installed on one side of each of the two sets of sliding blocks 15. A corresponding spring 17 is sleeved on each of the two fixed posts 16. The two ends of the spring 17 are respectively fixedly installed on the side of the sliding block 15 and the first housing 12 that are close to each other.

[0029] During use, the dosing port 2 can be quickly disassembled and reassembled, making it easy to perform deep cleaning and thus easier to use next time. This improves the convenience and flexibility of using the dosing port 2.

[0030] Each of the L-shaped clamps 7 has a mounting ring 13 fixedly installed on one side. Each mounting ring 13 has a hook 14 connected to it via an external connecting rope, and the hook 14 is compatible with the fixing ring 8. Two mounting slots 9 are symmetrically formed on the cabinet body 1. A corresponding mounting block 10 is slidably installed in each of the two mounting slots 9. Both mounting blocks 10 are fixedly installed to the fixing sleeve 11. The sides of the two first housings 12 that are close to each other are open. Each of the fixing sleeve 11 has a corresponding reinforcing slot 18 on both sides. A corresponding reinforcing block 19 is slidably installed in each of the two reinforcing slots 18, and both reinforcing blocks 19 are fixedly installed to the corresponding L-shaped clamps 7.

[0031] In use, by pulling the two hooks 14 away from each other, the two hooks 14 will move away from each other and cause the two L-shaped clamps 7 to move closer to each other, which will also cause the two corresponding sliding blocks 15 to move, thereby compressing the corresponding springs 17. By releasing the two hooks 14, the two L-shaped clamps 7 will automatically reset and can be fixedly installed on the replaced dosing port 2. Therefore, it is easy to perform deep cleaning so that it can be used again next time, further improving the convenience and flexibility of disassembly and assembly. Example

[0032] Reference Figure 7 , 8The dosing port mechanism also includes two second housings 20 symmetrically fixedly installed on the cabinet 1. A screw 22 is rotatably installed in one of the second housings 20. The screw 22 has a bidirectional thread and two connecting blocks 23 are symmetrically screwed onto the screw 22. A corresponding arc plate 21 is fixedly installed on one side of each of the two connecting blocks 23. A turbine 24 is fixedly installed at one end of the screw 22. A worm gear 25 is adapted to the turbine 24. A knob 26 is fixedly installed at one end of the worm gear 25. A limit rod 28 is fixedly installed in the other second housing 20. Two other connecting blocks 23 are symmetrically slidably sleeved on the two limit rods 28. The other two connecting blocks 23 are fixedly installed on the other side of the arc plate 21. A support frame 27 is fixedly installed on one of the second housings 20. One end of the worm gear 25 is rotatably installed on the support frame 27. The two arc plates 21 are clamped to the dosing port 2.

[0033] In use, by rotating the knob 26, the knob 26 rotates, which in turn drives the worm gear 25 to rotate. The rotation of the worm gear 25 drives the turbine 24 and the screw 22 to rotate. The rotation of the screw 22 drives the two connecting blocks 23 to move closer together and further away from each other, which in turn drives the two arc-shaped plates 21 to move further away from each other and to clamp and fix the dosing port 2. This allows the dosing port 2 to be disassembled. Then, by rotating the knob 26 in the opposite direction, the dosing port 2 can be installed and fixed. Therefore, the convenience and flexibility of cleaning, disassembly and replacement of the dosing port 2 can be further improved.

[0034] Reference Figure 8 Both arc-shaped plates 21 are equipped with anti-slip pads, and the two second shells 20 are open on the side that is close to each other. The cabinet 1 is equipped with an exhaust port 4 and an air inlet 5 respectively, and an inspection door 3 is provided on one side of the cabinet 1.

[0035] When in use, the anti-slip pads can be added to increase friction, thereby further improving the stability and firmness of the installation and clamping.

[0036] This utility model also proposes a perchloric acid fume hood, which includes a chemical dosing port structure for the perchloric acid fume hood. The specific structure of the chemical dosing port structure for the perchloric acid fume hood is referred to the above embodiments. Since this perchloric acid fume hood adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. This application employs two different disassembly and assembly methods, which can be selected according to usage requirements, further improving the flexibility and adaptability during use.

[0037] The perchloric acid fume hood described in this application is existing technology equipment, therefore the specific internal structure and installation and use process are not described in detail, and conventional installation techniques are used for installation and connection.

[0038] The present application embodiment describes a dosing port structure for a perchloric acid fume hood and the implementation principle of the perchloric acid fume hood as follows: When the dosing port 2 needs to be disassembled for cleaning and replacement, the two hooks 14 are pulled away from each other. The two hooks 14 moving away from each other will cause the two L-shaped clamps 7 to move closer to each other, and will also cause the corresponding two sliding blocks 15 to move, thereby compressing the corresponding springs 17. At this time, the reinforcing block 19 will disengage from the reinforcing groove 18 and install the two hooks 14 on the corresponding fixing ring 8, thereby allowing the dosing port 2 to be disassembled. The new dosing port 2 is then installed by fitting the mounting block 10 on the fixing sleeve 11 with the mounting groove 9. By releasing the two hooks 14, the two L-shaped clamps 7 will automatically reset, and the replaced dosing port 2 can be fixedly installed. Therefore, it is convenient to perform deep cleaning so that it can be used again next time, further improving the convenience and flexibility of disassembly and assembly. By rotating knob 26, the knob 26 rotates, which in turn drives worm gear 25 to rotate. The rotation of worm gear 25 drives turbine 24 and screw 22 to rotate. The rotation of screw 22 drives two connecting blocks 23 to move closer together and further away from each other, which in turn drives two arc-shaped plates 21 to move further away from each other and engage with the clamping and fixing of the dosing port 2. This allows the dosing port 2 to be disassembled. Then, by rotating knob 26 in the opposite direction, the dosing port 2 can be installed and fixed. Therefore, the convenience and flexibility of cleaning, disassembly and replacement of the dosing port 2 can be further improved.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
