Abstract

The utility model discloses a defoaming head for eliminating mixed bubble from paste materials under vacuum conditions, which is composed of a central tube, a net frame, a braiding net and a bottom cover. The utility model is vertically arranged on the top part of a tank body communicated with a negative pressure source, and the utility model can have action of eliminating bubble towards the paste materials absorbed by negative pressure, the paste materials flow through the defoaming head. The defoaming head does not only have simple structure, but also makes continuous production and process control possible.

Description

The vacuum defoamation head

The utility model relates to a kind of lotion that is, removes the device that mixes bubble in particular for the transparent lotion material in the cosmetics.

Transparent lotion cosmetics are a kind of emerging cosmetics types, have attracted vast consumer with its glittering and translucent and elegant practicality.Yet, although mostly this transparent lotion material is to process under vacuum condition, but in the production process of preparation, still sneak into a large amount of bubbles inevitably, therefore, deaeration just become before this series products can or can in an indispensable procedure, regrettably, this deaeration equipment still is a blank at present at home.

For addressing this problem, current common way is material to be placed under the vacuum condition leave standstill, its can be divided into before the can again or can after leave standstill two kinds: leave standstill the finished product materials after exactly reaction being finished before the can, under vacuum condition, continue in retort, to stay for some time, and then discharging can, this method is because the contact area of material and negative pressuren zone is limited, and deep layer deaeration effect is undesirable, and needs long time; Leave standstill after the can then is that the finished product materials that will contain bubble pours into earlier in the finished product bottle, and then deliver under the vacuum condition and place a period of time, though this method time is shorter than the former, the deaeration effect is also better than the former, but in the deaeration process, because air bubble expansion, material overflow, and often need the secondary supplement can.

The purpose of this utility model is the vacuum defoamation device that a kind of overflow-type simple in structure will be provided, and it can remove the bubble that mixes in the lotion effectively.

For reaching this purpose, the utility model has a central tube that vertically stretches into, and has the center and the welding mutually with it of the rack in grid hole around it passes one, and columnar netting places in the rack and with bottom and is tightened by screw thread.The end mouth of central tube is 2～5 millimeters apart from the inner plane of bottom; The base, grid hole of rack is 15～20 millimeters apart from the inner plane of bottom.The utility model is vertically mounted on the corresponding flange in deaeration tank top by the screw thread on the rack.

The deaeration jar communicates with negative pressure source during work, material sucks from top to bottom, when the central tube of deaeration head of flowing through arrives its bottom, turn back upwards to change and flow to, because the effect of negative pressure and dilatation, add the gap of unit weight, lotion translational speed in the material is slowed down, and bubble has the tendency of an acceleration at the time Hou Ze that expands, so just produced the speed difference that a lotion and bubble move up, move on to place, outlet grid hole on material continues, under pressure reduction and gravity effect, change the flow direction once more, but the stressed and flow direction of the lotion in the material and bubble is no longer identical this moment.Simultaneously, because the retardation of netting, the contact surface that has not only increased material and negative pressure of vacuum district amasss, and owing to netting overflows bubble to the retardation of lotion much larger than the retardation to bubble smoothly.Pass netting lotion can gather under the gravity effect fall into downwards jar at the bottom of.

The utility model is simple in structure, overcome leave standstill the formula contact surface long-pending little, the time long, the deficiency of weak effect, with right, replace leaving standstill the formula deaeration with overflow-type and also make and realize producing continuously and process control becomes possibility.

Concrete structure of the present utility model is as follows:

Fig. 1 is a profile of the present utility model.

Fig. 2 is a sectional drawing of the present utility model.

This device is vertically mounted on the vacuum defoamation tank top, it by central tube 1., rack 2., 4. 3. netting form with bottom.2. rack is the main part of deaeration head, has the grid hole on every side, is the window that bubble is overflowed, and head is processed with screw thread, in order to be installed on the corresponding flange of tank deck; 1. central tube passes rack centre bore 2. and welding with it; Netting cylindraceous 3. be installed in rack 2. in and 4. be tightened with bottom.Central tube after assembling lower port 1. is apart from 2～5 millimeters of bottom inner planes 4., 10～18 millimeters apart from rack base, grid hole 2..
