[0002] PFA refers to plastics made of fluororesin. The main varieties are polytetrafluoroethylene, tetrafluoroethylene-ethylene copolymer, tetrafluoroethylene-hexafluoropropylene copolymer and trifluorochloroethylene-ethylene copolymer. Since fluoroplastics contain fluorine atoms in their molecular structure, they have many excellent properties, such as excellent electrical insulation, high heat resistance, outstanding oil resistance, solvent resistance and wear resistance, good moisture resistance and low temperature resistance. Due to its excellent chemical properties, it is widely used in laboratory equipment.

[0003] In the prior art, the sealed PFA drum for steaming and cleaning used in the laboratory consists of a barrel body and an internal placement rack. However, in actual use, the placement rack needs to be taken out after pickling, and then the drum needs to be steamed, cleaned and drained. The operation is inconvenient and the acid vapor generated by pickling is prone to leakage, which has an adverse effect on the health of the experimenters. Therefore, we propose a sealed PFA drum for steaming and cleaning to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A sealed PFA drum for steaming and cleaning, comprising a barrel body 1, wherein a rack assembly is arranged in the barrel body 1, wherein:

[0024] The placement rack assembly includes a vertical tube 2, a plurality of through holes are provided on the lower end side wall of the vertical tube 2, and a plurality of curved tubes 3 are connected to the side wall of the vertical tube 2, the opening direction of the curved tube 3 is upward, a connecting frame 4 is slidably sleeved on the vertical tube 2, and a plurality of vertical grooves for making way for the curved tubes 3 are provided on the connecting frame 4, a plurality of rotating rods 6 are rotatably connected to the side wall of the connecting frame 4, a cup sleeve 7 is detachably connected to one side of the rotating rod 6, and a gear 8 is fixedly connected to the end of the rotating rod 6 away from the connecting frame 4, a rack 9 meshing with the gear 8 is provided on the inner wall of the barrel body 1, a control rod 10 is fixedly connected to the upper end of the connecting frame 4, and a gate-shaped frame 11 is fixedly connected to the upper end of the control rod 10, a limit block 12 is rotatably connected to the gate-shaped frame 11, and a strip groove is provided on the limit block 12.

[0025] Furthermore, the barrel body 1 includes a barrel body 101 and a barrel cover 102, the placement component is arranged in the barrel body 101, the upper ends of the vertical pipe 2 and the limit block 12 pass through the barrel cover 102, and a sealing gasket 103 is arranged on the upper surface of the barrel cover 102 near the vertical pipe 2 and the limit block 12.

[0026] Furthermore, the lower end of the vertical tube 2 is fixedly connected with a conical block 13, and the inner wall of the lower end of the barrel body 1 is provided with a positioning block 14 matching the conical block 13. This design is used to position the vertical tube 2 and enables the entire placement rack assembly to rotate around the vertical tube 2 as the axis to ensure that the rack 9 and the gear 8 are in a meshing state.

[0027] Furthermore, the cup sleeve 7 includes a C-shaped rod, one side of the C-shaped rod is fixedly connected with a connecting rod 701, and the end of the connecting rod 701 away from the C-shaped rod is fixedly connected with a cup holder 702, the inner wall of the C-shaped rod is provided with a horizontal bar 703, and the side wall of the rotating rod 6 is provided with a groove matching the horizontal bar 703, wherein the cross section of the C-shaped rod is C-shaped and can be stuck on the rotating rod 6, and the horizontal bar 703 cooperates with the groove to ensure that the C-shaped rod and the rotating rod 6 will not rotate relative to each other, thereby ensuring that the relative position of the cup sleeve 7 and the rotating rod 6 will not change during use.

[0028] Furthermore, a plurality of surrounding push rods 15 are fixedly connected to the upper end of the curved tube 3. This design is used to prevent the curved tube 3 from being completely in close contact with the laboratory vessel, thereby preventing the opening of the curved tube 3 from being blocked.

[0029] Furthermore, a groove 5 is provided on the upper surface of the barrel cover 102, and the limit block 12 is arranged close to the groove 5. In this design, the groove 5 is used to limit the position of the limit block 12 to prevent the limit block 12 from being displaced during the cleaning process and causing the connecting frame 4 to move downward. At the same time, the groove 5 is also used to facilitate the user to pinch the limit block 12 that has been placed horizontally.

[0030] In the utility model, the user selects a cup sleeve 7 of appropriate size according to the laboratory utensils to be cleaned, and then places the utensils in the cup sleeve 7, and then splices the placement rack assembly with the barrel cover 102 (specifically, the vertical pipe 2 and the limit block 12 pass through the sealing gasket 103 on the barrel cover 102), and then puts the placement rack assembly into the barrel body 1 and uses the barrel cover 102 to seal the upper end of the barrel body 1, and then uses the vertical pipe 2 to inject cleaning agent or neutralizing reagents such as strong acid and strong alkali into the barrel body 1 to clean the laboratory utensils. If high-temperature boiling cleaning is required, it can also be confirmed whether to connect the upper end of the vertical pipe 2 to the gas recovery and processing pipeline for boiling operation according to the current reagent used in the barrel body 1. After the cleaning is completed, the user pulls the limit block 12 to drive the entire connecting frame 4 to move upward, and then rotates the limit block 12 so that the limit block 12 is placed horizontally. The barrel cover 102 is on, so that the connecting frame 4 remains in this state. At this time, the rotating rod 6 on the connecting frame 4 rotates with the cooperation of the gear 8 and the rack 9, so that the cup sleeve 7 rotates synchronously, and the laboratory vessel is also flipped to be buckled on the elbow 3, so that the laboratory vessel can be drained and then rinsed with clean water, and the laboratory vessel washed with clean water can be drained in this state. After use, the limit block 12 is rotated to a vertical state, and then the barrel cover 102 is opened to take out the placement rack assembly. This kind of sealed steaming and cleaning PFA barrel not only ensures the sealing of the entire barrel, but also takes into account the recovery of harmful gases, and has inverted laboratory vessels for draining and other functions, optimizes the cleaning process, is convenient for users to use, reduces labor intensity, improves cleaning efficiency, and has a relatively simple structure without increasing equipment costs too much.
