Abstract
The utility model relates to a lithium tetrafluoroborate drying device, which comprises a barrel. A hollow sandwich is arranged on the lateral wall of the barrel, an inner container is arranged inside the barrel, a cover board is arranged on the top of the inner container, an upper cover board is arranged on the top of the barrel, a first vacuum tube is arranged on the cover board, and a second vacuum tube is arranged on the upper cover board. The lithium tetrafluoroborate drying device has the advantages that the stainless steel barrel bears most of pressure brought by vacuity, the inner container only bear smaller part of the pressure brought by vacuity, accordingly the inner container cannot deform or be cracked due to reduced strength under heating, materials and boron trifluoride and hydrogen fluoride gases emitted by the materials under heating cannot directly contact with the metal barrel, and corrosive damage of the device and pollution to the materials can be avoided.
Description
Technical field
The utility model relates to a kind of compound drying equipment, particularly a kind of LiBF4 drying equipment.
Background technology
LiBF4 normally carries out material reaction and makes in organic solution, this product is met water and promptly can be decomposed, and therefore must adopt vacuum drying method to carry out heat drying.Existing vacuum dryer comes with some shortcomings, traditional drying equipment common metal material is made, can emit corrosive gas such as boron trifluoride, hydrogen fluoride gas after containing the mixed material heating of LiBF4, this class gas can cause heavy corrosion to hardware, also can influence product quality simultaneously; If the drying equipment that adopts plastics such as polytetrafluoroethylene (PTFE) or polypropylene to make, plastic material is difficult for being corroded, but the back physical strength that is heated reduces, the vacuum that can bear is lower, effect is undesirable behind the product drying, if gas clean-up, cylindrical shell can produce distortion even break.
The utility model content
The purpose of this utility model provides a kind of LiBF4 drying equipment, can effectively solve problems such as the vacuum that physical strength reduces, bears under equipment corrosion-resistant that prior art exists, the heating state is lower, product drying weak effect.The utility model relates to a kind of LiBF4 drying equipment, comprise cylindrical shell, the sidewall of described cylindrical shell is provided with hollow interlayer, be provided with inner bag in the described cylindrical shell, described inner bag top is provided with cover plate, described cylindrical shell top is provided with upper cover plate, and described cover plate is provided with first vacuum tube, and described upper cover plate is provided with second vacuum tube.It is fixing on the cover board that described first vacuum tube passes upper cover plate.Described first vacuum tube is provided with first vacuum meter and first valve.Described second vacuum tube is provided with second vacuum meter and second valve.Described hollow chuck is provided with hot water inlet near the side of bottom, and described hollow chuck is provided with hot water outlet near the side at top, and hot water inlet and hot water outlet lay respectively at the both sides of cylindrical shell.Described hot water inlet is provided with the 3rd valve, and described hot water outlet is provided with the 4th valve.Described cylindrical shell is the cylindrical container of good seal, and described inner bag is the cylindrical container of good seal.Described cylindrical shell is that stainless steel material is made.Described chuck is that carbon steel material is made.Described inner bag is that polypropylene material is made.Advantage of the present utility model is to have born the pressure that most of vacuum is brought with stainless steel cylinder, make inner bag only bear the pressure that smaller portions vacuum is brought, so just inner bag is out of shape because of heat intensity reduces or breaks, material and the material not direct cylindrical shell of contacting metal material of the boron trifluoride of emitting and hydrogen fluoride gas that is heated has simultaneously been avoided to the corrosion-damaged of equipment with to the pollution of material.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described.
Comprise cylindrical shell 1 among the figure, the sidewall of described cylindrical shell is provided with hollow interlayer 2, is provided with inner bag 3 in the described cylindrical shell, described inner bag top is provided with cover plate 4, described cylindrical shell top is provided with upper cover plate 5, and described cover plate 4 is provided with first vacuum tube 7, and described upper cover plate is provided with second vacuum tube 6.It is fixing on the cover board that described first vacuum tube passes upper cover plate.Described first vacuum tube 7 is provided with first vacuum meter 10 and first valve 11.Described second vacuum tube 6 is provided with second vacuum meter 8 and second valve 9.First vacuum tube and second vacuum tube are connected with a vacuum system respectively.
Described hollow chuck is provided with hot water inlet 12 near the side of bottom, and described hollow chuck is provided with hot water outlet 13 near the side at top, and hot water inlet and hot water outlet lay respectively at the cylindrical shell both sides.
Described hot water inlet is provided with the 3rd valve 14, and described hot water outlet is provided with the 4th valve 15.Described cylindrical shell is the cylindrical container of good seal, and described inner bag is the cylindrical container of good seal.Described cylindrical shell is that stainless steel material is made.Described chuck is that carbon steel material is made.Described inner bag is that polypropylene material is made.First vacuum tube, second vacuum tube are that polypropylene material is made.
The utility model at work, earlier cleaned equipment dries up equipment with the dry air that purifies, and in dry environment, synthetic good a certain amount of LiBF4 is joined in the equipment inner bag, cover plate and upper cover plate is installed, assurance inner bag and cylindrical shell good seal.Open vacuum system, open second valve of second vacuum tube, by observing second vacuum meter and adjusting second valve, make the interior vacuum of cylindrical shell reach the appointment requirement, open the first vacuum port valve then, by observing first vacuum meter and adjusting first valve, make the interior vacuum of inner bag a little more than inner barrel vacuum, open the hot water heating circulation system after regulating vacuum, open the 3rd valve and the 4th valve, the hot water of squeezing into uniform temperature in the chuck carries out heating, drying to material, in the drying course by regulate vacuum that first valve and second valve control cylindrical shell in specifying claimed range and the vacuum of inner bag a little more than the vacuum of cylindrical shell.After drying materials reaches the fixed time, close hot water cyclesystem, make the temperature of inner bag and cylindrical shell drop to normal temperature gradually; Close first valve and second valve, close and disconnect vacuum system, open first valve and second valve charges into dry gas in inner bag, make inner bag and cylindrical shell vacuum drop to zero, open loam cake then and take out material, drying technology process is finished, and prepares to enter packaging process.
The utility model has born the pressure that most of vacuum is brought with stainless steel cylinder, make inner bag only bear the pressure that smaller portions vacuum is brought, so just inner bag is out of shape because of heat intensity reduces or breaks, material and the material not direct cylindrical shell of contacting metal material of the boron trifluoride of emitting and hydrogen fluoride gas that is heated has simultaneously been avoided to the corrosion-damaged of equipment with to the pollution of material.
