Abstract
The invention discloses a flash evaporation type micromolecule removing device with a nitrogen spray pipe, relating to equipment for chemical production, in particular to equipment for producing high-temperature vulcanized methyl vinyl silicone rubber. In the invention, the nitrogen spray pipe is arranged in the middle of a tank body in the vacuum area of the micromolecule removing device, wherein two ends of the nitrogen spray pipe are arranged outside the tank body, the tank body is transversely penetrated through the middle of the nitrogen spray pipe,and a nitrogen nozzle is arranged on the nitrogen spray pipe. The invention has the advantages that the problems that the existing equipment has poor micromolecule removing effect, the content of residue in the product is relatively high, the vacuum degree in the micromolecule removing device is unsatisfactory, and the like are solved.
Description
Technical field
The present invention relates to Chemical Manufacture equipment, especially for the equipment of producing methyl ethylene high temperature vulcanizing silicone rubber.
Background technology
It is the very important device that is used to produce methyl ethylene high temperature vulcanizing silicone rubber that Flash Type is taken off low molecule device.In this device, it will be finished and destroy temporary catalyst, under the condition of high temperature and high vacuum, the flash distillation from material of unreacted low molecule be come out then.Last methyl ethylene high temperature vulcanizing silicone rubber is extruded product by the screw extruder that takes off the bottom of hanging down the molecule device.
Existingly take off low molecule device and have following shortcoming: it is relatively poor one, to take off low molecular effect; Two, the content of residue in product is than higher, and peculiar smell is heavier in the product; Three, the vacuum of taking off in the low molecule device is undesirable.
Summary of the invention
The purpose of this invention is to provide a kind of Flash Type that has the nitrogen shower and take off low molecule device, the invention solves that existing equipment exists to take off low molecular effect relatively poor, the content of residue in product is than higher, takes off problems such as vacuum in the low molecule device is undesirable.
The Flash Type that has the nitrogen shower of the present invention is taken off low molecule device, be provided with the nitrogen shower at the tank body middle part of taking off low molecule device vacuum area, nitrogen shower two ends are arranged on the tank body outside, and tank body is laterally run through at nitrogen shower middle part, and the nitrogen ejiction opening is arranged on the nitrogen shower.
The Flash Type that has the nitrogen shower of the present invention is taken off low molecule device, in taking off low molecular vacuum area, has set up a nitrogen shower of laterally wearing, and its effect is conspicuous.Introduced the nitrogen of the incoagulability of inertia in vacuum system, it has following three advantages: it is better than original 1, to take off low molecular effect, has guaranteed the low molecular effect of taking off when the unit production capacity is big; 2, because the intervention of incoagulability nitrogen can make the analyte of catalyst remove thereupon, effectively reduce the content of residue in product, alleviate or eliminates foreign odor and distinguish the flavor of; 3, can also regulate the vacuum of taking off in the low molecule device by the flow of regulating nitrogen simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is the A-A cutaway view of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the present invention is done detailed explanation.
Consult Fig. 1, Fig. 2, the Flash Type that has the nitrogen shower is taken off low molecule device, be provided with nitrogen shower 2 at tank body 1 middle part of taking off low molecule device vacuum area, nitrogen shower 2 two ends are arranged on tank body 1 outside, tank body 1 is laterally run through at nitrogen shower 2 middle parts, and nitrogen ejiction opening 2-2 is arranged on the nitrogen shower 2.Nitrogen shower 2 two ends have to connect uses flange 2-1.
Claims (2)
1. the Flash Type that has the nitrogen shower is taken off low molecule device, it is characterized in that, be provided with nitrogen shower (2) at cartridge type tank body (1) middle part of taking off low molecule device vacuum area, nitrogen shower (2) two ends are arranged on tank body (1) outside, tank body (1) is laterally run through at nitrogen shower (2) middle part, and nitrogen ejiction opening (2-2) is arranged on the nitrogen shower (2).
