Embodiment 1

[0032] Such as Figure 1-3 As shown, a double-temperature vacuum drying oven with one chamber includes a furnace body 1 and a vacuum pump 10. The furnace body is provided with a vacuum interface, which communicates with the air inlet of the vacuum pump 10 through a pipeline, and the furnace body is provided with a first A heating device and a second heating device, the first heating device includes a heating water tank 8, a water pump 9 and a water pipe 7, wherein the water tank 8 and the water pump 9 are arranged outside the body of heater 1, and the water pipe 7 is arranged in the interlayer of the side wall of the body of furnace, The water inlet of the water pipe 7 communicates with the water outlet of the water pump 9, the water outlet of the water pipe 7 communicates with the water tank 8, and the water inlet of the water pump 9 communicates with the water tank 8 to form a hot water circulation loop. The water tank 8 is provided with an electric heating tube. The second ...

Embodiment 2

[0044] Utilize the method for drying in a double-temperature vacuum drying oven in one chamber, comprising the steps:

[0045] Step 1. Put the glass sheet into the baking tray, put the baking tray on the heat exchange support, close the furnace door, close the exhaust valve, and the furnace chamber is in a sealed state;

[0046] Step 2, start the second solenoid valve, start the vacuum pump, and evacuate the furnace chamber;

[0047] Step 3: Open the valve on the water pump, and the hot water circulates in the water pipe to heat the first chamber at a heating temperature of 70 degrees to dry the moisture on the surface of the glass sheet; at the same time, control the electric heating plate at the bottom of the second chamber to work , heating the second chamber, the heating temperature is 120 degrees;

[0048] Step 4. When the pressure in the chamber of the furnace body is -0.098MPa, the first electromagnetic valve is opened, and the liquid medicine is added to the material ...

Abstract

The invention discloses a one-room dual-temperature vacuum drying box and a drying method. The drying box comprises a furnace body and a vacuum pump; the furnace body is communicated with an air inlet of the vacuum pump through a pipeline, a first heating device and a second heating device are arranged on the furnace body, furnace body cavities comprise a first cavity and a second cavity which are communicated, the first heating device is used for heating and drying products placed in the first cavity, the second heating device is used for heating liquid medicines in the second cavity so as to enable the water to be instantly diffused, and the heating temperature of the first cavity is different from the heating temperature of the second cavity; the drying process requirement is different, the process needs to be carried out under the different temperature conditions, one-room dual-temperature control is needed, the one-room dual-temperature vacuum drying box is used, multiple process needs can be met at the same time, and the beneficial effects of being convenient to operate and capable of enabling the efficiency to be doubled are achieved; the vacuum furnace is used for drying the products, the furnace body cavities are closed, and therefore cleanness is high; dust, impurities and water spots on the surface in the furnace body can be pumped out through the vacuum pump, and in the heating process, the products are not polluted.

Description

technical field [0001] The invention relates to a one-chamber double-temperature vacuum drying oven and a drying method. Background technique [0002] Some special products need to be dried with different processes on the surface, such as special glass sheets, etc., drying and surface vaporization diffusion, the two need different temperature treatments in the same environment, and there is no one-room dual-temperature vacuum in the prior art The drying device needs to be carried out step by step and with multiple devices. The operation is cumbersome and inefficient, and it is completed in an atmospheric oven. As a result, when the product is heated and dried, the water and oil stains on the product surface will leave stains after vaporization, and During the heating process, dust, sundries, etc. will pollute the product. Contents of the invention [0003] The purpose of the present invention is to provide a one-chamber dual-temperature vacuum drying oven and a drying met...
