The utility model can also be achieved in that thermal insulation board 22 is housed on the pressure plare 14 that thermal insulation board 22 mainly is the heat-insulating problem that solves hopper 15 and pressure plare 14 tops; Feed hopper liner 21 is housed in the hopper 15, and feed hopper liner 21 is the polyfluortetraethylene plate material, and it mainly is to prevent the adhesion problems of waste plastics to hopper 15; Between interior coaming plate 17 and the peripheral board 25 thermal insulation layer 16 is housed, thermal insulation layer 16 is to prevent that the heat that heats in the casing from outwards distributing; Blast pipe 24 is housed on the top board 23, and it can be used as the waste gas outlet in the heating casing.

Good effect of the present utility model is:

1, this machine is to adopt hot-air sterilization, general bacterial propagule kept 1 hour under xeothermic 80--100 ℃ temperature, can be killed, and the temperature of unmaking of this product can reach 130 ℃, and also about 1 hour, the residual liquid that adds in the upper tubing forms steam to holding temperature after heating, so inside and outside virus, the bacterium of woven hose then can all be killed, and molten molten distortion takes place because of being subjected to high temperature in the plastics of this moment, is unmaking middle sterilization thereby reached, the purpose of unmaking in sterilization.

2, this product not only can solve the noise of other method of unmaking big, pollute heavy, labour intensity is big and ineffective problem, and the raw material that the waste plastic after the sterilization of unmaking can be used as plastic molding and processing plant is utilized.

Description of drawings.

Fig. 1 is a structure cutaway view of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, 2.Open the chamber door of heating casing, will give up woven hose or useless syringe are packed in the hopper 15, close chamber door.Referring to Fig. 2, knife switch HK closes, ' falling ' button AR behind the power connection, is pressed in indicator lamp ZA work, referring to Fig. 1, be fixed on the electric machine support 12 on the top board 23 motor D is housed, motor D drives travelling gear 10, and travelling gear 10 drives transmission worm screw 5, transmission worm screw 5 drives transmission worm gear 4, and transmission worm gear 4 drives pressure leading screw 1 and moves down.Pressure plare 14 is fixed on the lower end of pressure leading screw 1 by card 13, when pressure leading screw 1 moves down, pressure plare 14 is pressed on useless woven hose or the useless syringe, spacing control 7 is fixed on the pressure leading screw 1, when pressure leading screw 1 drops to limit controller 7 and touches travel switch CY1, referring to Fig. 2, travel switch CY1 disconnects, and motor D shuts down.This moment, heating disinfection was partly started working, and referring to Fig. 2, power switch K connects the power input of temperature controller WKY, and the coil of relay 2JD connects the control output end of temperature controller WKY, and thermocouple PU connects the signal input part of temperature controller WKY, and thermocouple PU measures temperature.Dotted portion is the schematic internal view of temperature controller WKY among Fig. 2, and temperature controller WKY is a WPCK-BAI type temperature measurement-control instrument.Referring to Fig. 2, power switch K connects the power input of temperature controller WKY, stir power switch K, the coil working of relay 1JD makes normally opened contact 1JD1, the 1JD2 closure of relay 1JD, and this contact makes the coil working of relay 2JD, its normally opened contact 2JD1,2JD2 closure, indicator lamp ZB work, resistance wire RL begins heating, heats up; When resistance wire RL is heated to 130 ℃ of design temperatures, thermocouple PU connects the signal input part of temperature controller WKY, the signal that thermocouple PU will arrive set temperature value is transferred to temperature controller WKY, the coil of relay 1JD is quit work, often the leaving of relay 1JD touches 1JD1 and 1JD2 transfers off-state to by closure state, the coil of relay 2JD is quit work, the normally opened contact 2JD1 of relay 2JD, 2JD2 transfers off-state to by closure state, because relay 2JD connects the control output end of temperature controller WKY, so controlling resistance silk RL stops heating, by switching on and off of temperature controller WKY controlling resistance RL, thereby reach the purpose of constant temperature.After the waste plastics in the hopper 15 is subjected to the molten distortion of hot melt,, the waste plastics pressurized in the hopper 15 is shaped once more by ' falling ' button AR.After the complete pressurized of the waste plastics in the hopper 15 is shaped,, press ' liter ' button AL referring to Fig. 1, motor D work, drive pressure leading screw 1 by running part and move up, pressure plare 14 leaves the waste plastics that pressurized is shaped, when pressure leading screw 1 rises to limit controller 7 and touches travel switch CY2, referring to Fig. 2, travel switch CY2 disconnects, and motor D shuts down, and opens chamber door then, cool off after 5 minutes, the shaping waste plastics in the hopper 15 is drawn off.Referring to Fig. 1, the handwheel 6 of pressure leading screw 1 upper end dress is upper and lower mobile with manual adjustments pressure leading screw 1 under power failure or other situation.
