Description
Technical field
The utility model relates to a kind of equipment of chemical field, is meant the device that can the lower-molecular substance in polymeric fluid material such as the polysiloxane-based adhesive be removed especially.
Background technology
At chemical technology field particularly is technical field of macromolecules; Product regular meeting synthetic or preparation contains impurity or volatile substance (like the compound of small-molecular weight etc.) and need remove, and for example just contains the not various completely low-molecular-weight dimethyl siloxane ring bodies of polymerization (mainly being D-3D10) of part in the polysiloxane-based adhesive commonly used in the electronics industry.Above-mentioned lower-molecular substance volatilizees because of electronic installation is heated when electronic installation uses, condensation during cooling, as condense in the hard contact surface and can cause contact insulation short circuit or sparking to cause fault.How the lower-molecular substance in the polysiloxane-based adhesive is removed is a difficult problem always; Its reason one is the polysiloxanes heating temperature when surpassing more than 190 ℃; Understand progressively cracking chain rupture and form new lower-molecular substance; It two is that the operating efficiency or the accessible vacuum of conventional industrial vacuum pump under said temperature is extremely low to the efficient that removes lower-molecular substance, and it three is owing to do not allow to exist bubble in the adhesive, so can not stir.Therefore, it is very important to solve removing electronics industry of lower-molecular substance in the polysiloxane-based adhesive.
Summary of the invention
The goal of the invention of the utility model is to disclose a kind of device that removes that can remove lower-molecular substance in the polysiloxane-based adhesive fast.
The technical solution that realizes the utility model is following: comprise tank body; Be covered with a motor on the key tank body; The motor shaft of motor drives plate-like connector and the vertical scraper plate rotation of being located at plate-like connector edge; Tank body below is provided with condensing unit, and the sidewall of tank body has heater and discharging opening, on covered charging aperture.
Form narrow slit between described scraper plate and the tank body, charging aperture is positioned at the top, edge of plate-like connector.
Described heater is that one of the outer wall formation of tank body has the jacket structured of inner chamber, and chuck is provided with inlet and liquid outlet.
The condenser pipe of described condensing unit places in the tank body, and there are cooling water inlet, coolant outlet and condensate outlet in the below of condenser pipe.
The width of the narrow slit between described scraper plate and the tank body can be regulated.
Be provided with the vacuum shaft envelope between described motor shaft and the loam cake, the tank body below is provided with vacuum orifice.
The utility model design is unique, simple in structure, and special the adaptation removes the macromolecular material of certain viscosity such as the lower-molecular substance in the polysiloxane-based adhesive, and removal efficiency is high, can not produce bubble for adhesive, can guarantee the high-quality of product.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
See also Fig. 1; The specific embodiment of the utility model is following: comprise tank body 1, it has certain volume, and key is to be provided with a motor 3 at loam cake 2; The motor shaft 4 of motor 3 drives plate-like connector 16 and 5 rotations of the vertical scraper plate of being located at plate-like connector 16 edges; Tank body 1 below is provided with condensing unit, and the sidewall of tank body 1 has heater and discharging opening 6, and charging aperture 7 is arranged on the loam cake 2; During actual the use; Polysiloxane-based adhesive is got into by charging aperture 7; Drop on the plate-like connector 16 between motor shaft 4 and the scraper plate 5, and then under the guiding of rotary centrifugal force and plate-like connector 16, flow to and be located in the scraper plate 5 and the interval between the tank body 1 at plate-like connector 16 edges, adhesive then contacts with the inwall of tank body 1; Then adhesive flows downward along inwall; In the time of scraper plate 5 rotations simultaneously adhesive spread to the thin layer of setting, at this moment there is the motion of downward and horizontal both direction simultaneously in adhesive, and scraper plate 5 can make the inwall formation thin layer of adhesive at tank body 1 on the one hand; The proper extension adhesive helps lower-molecular substance and from adhesive, evaporates at the flowing time of inwall simultaneously; For increasing the evaporation rate of lower-molecular substance; The sidewall of tank body 1 has heater; Heater is that one of the outer wall formation of tank body 1 has the jacket structured of inner chamber, and chuck is provided with inlet 8 and liquid outlet 9, injects heated oils or steam or other through inlet 8 and has the liquid of design temperature; Make the inwall of tank body 1 be heated to of the volatilization of the temperature of setting with the lower-molecular substance in the quickening adhesive; The adhesive that removes lower-molecular substance flows out along the discharging opening 6 that internal face flow to tank body 1 side wall lower ends, and the lower-molecular substance that volatilizes runs into the condenser pipe 10 of the condensing unit of tank body 1 below setting, is condensed into liquid rapidly; Flow downward along condenser pipe 10; The condenser pipe 10 of condensing unit places in the tank body 1, and there are cooling water inlet 11, coolant outlet 12 and condensate outlet 13 in the below of condenser pipe 10, and aforesaid condensate is discharged through collecting by condensate outlet 13; For accelerating the volatilization of lower-molecular substance; Should make between scraper plate 5 and the tank body 1 and form narrow slit; Then can make adhesive or polysiloxanes form thinner glue-line in the inner wall surface of tank body 1; And charging aperture 7 setting is positioned at the top, edge of plate-like connector 16, then help adhesive get into narrow slit with reduce adhesive bond other parts surface and increase the workload of removing residue, for ease of adapting to different adhesives or macromolecular material; The width of the narrow slit between scraper plate 5 and the tank body 1 can be regulated, to regulate the thickness of adhesive in inner wall surface; For improving the evaporation rate of lower-molecular substance; Can be with vacuum pumping in the tank body 1, adhesive is in the process that flows down along tank body 1 inwall, and liquid level as thin as a wafer is in the hot vacuum environment; Help the quick volatilization of lower-molecular substance; Improve the efficient of condensation simultaneously, therefore between motor shaft 4 and loam cake 2, be provided with vacuum shaft envelope 14, below tank body 1, be provided with vacuum orifice 15 to improve sealing.
