Description
Technical Field
The utility model relates to the technical field of production of environment-friendly materials, in particular to a temperature control and drainage device for a vacuum drying kiln.
Background
Vacuum drying is a method of drying under a vacuum condition and a pressure lower than atmospheric pressure. Under the vacuum condition, the boiling point of water is reduced, and the evaporation speed is accelerated, so that the drying speed of the material can be accelerated at a lower temperature. The moisture in the material continuously moves to the surface, the evaporation speed of the moisture is much higher than the speed of the moisture in the material, the moisture is directly evaporated by the internal temperature in the use process of the traditional vacuum drying kiln, the drying time is longer and the energy consumption is high.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides the temperature control and drainage device for the vacuum drying kiln, which has a reasonable structure and a good use effect.
In order to realize the purpose, the technical scheme provided by the utility model is as follows: a temperature control and water discharge device for a vacuum drying kiln comprises a kiln body, wherein one end of the kiln body is provided with a kiln door, the wall of an inner cavity at the other end is provided with a cooling coil pipe, two sides of the inner cavity of the kiln body are vertically fixed with a support, an air inlet area is reserved between the support and the wall of the inner cavity of the kiln body, a fan is arranged on the support, a heating pipe is arranged in the air inlet area, the bottom of the kiln body below the cooling coil pipe is provided with an inclined water guide surface, the kiln body at the lower side of the water guide surface is provided with a water collection hole which penetrates through the inside and the outside, and the outer side of the kiln body is provided with a water collection pipe connected with the water collection hole.
The heating pipe is a plurality of heating pipes which are in a shape of ' hui ', snake ' or ' ji ' and are fixed on the bracket.
The water collecting pipe is sequentially provided with a first valve, a second valve and a third valve.
After the scheme is adopted, after the material enters the vacuum drying kiln, the material is positioned between the brackets at two sides, the material is vacuumized by an external vacuum pump, the heating pipe is heated, hot air is blown to the material by the fan, so that the moisture in the material is evaporated, the cooling coil pipe is water-cooled or air-cooled (fixed on the inner cavity wall at the tail part of the kiln body), the evaporated water vapor meets the cooling coil pipe and is condensed into water, the water falls onto the water guide surface at the bottom of the kiln, the water is guided by the water guide surface and is discharged from the water collection hole into the water collection pipe, the first valve on the water collection pipe is a normally open valve, the second valve is a normally closed valve, the third valve is an output end, the second valve adopts a one-way valve according to requirements, the water is prevented from flowing back from the output end when in normal use, the scheme is used for quickly condensing and then discharging the moisture evaporated from the material, so that the time required by drying the material is greatly reduced, rational in infrastructure, excellent in use effect after this scheme of adoption.

Fig. 2 is a schematic view of the structure of the water collecting hole of the present invention.
Detailed Description
The utility model will be further described with reference to the accompanying drawings, in which preferred embodiments of the utility model are: referring to fig. 1 and fig. 2, the temperature control and water discharge device for a vacuum drying kiln in this embodiment includes a kiln body 201, a kiln door is opened at one end of the kiln body 201, a cooling coil 406 is installed on an inner cavity wall at the other end, supports 401 are vertically fixed at two sides of an inner cavity of the kiln body 201, an air inlet area is reserved between the supports 401 and the inner cavity wall of the kiln body 201, a fan is installed on the supports 401, heating pipes 405 are installed in the air inlet area, and the heating pipes 405 are multiple and fixed on the supports 401 in a shape of "hui", "snake" or "several". An inclined water guide surface is arranged at the bottom of the kiln body 201 below the cooling coil 406, a water collecting hole 407 which penetrates through the inside and the outside is arranged on the kiln body 201 on the lower side of the water guide surface, and a water collecting pipe 408 connected with the water collecting hole 407 is arranged on the outer side of the kiln body 201. The water collecting pipe 408 is provided with a first valve 409, a second valve 410 and a third valve 411 in sequence.
After the scheme is adopted, after the material enters the vacuum drying kiln, the material is positioned between the supports at the two sides, the material is vacuumized through an external vacuum pump, the heating pipe is heated, hot air is blown to the material through the fan, so that moisture in the material is evaporated, the cooling coil pipe is water-cooled or air-cooled (fixed on the inner cavity wall at the tail part of the kiln body), evaporated water vapor meets the cooling coil pipe and then condenses into water, the water falls onto the water guide surface at the bottom of the kiln, the water is discharged into the water collection pipe from the water collection hole through the water guide surface, the first valve on the water collection pipe is a normally open valve, the second valve is a normally closed valve, the third valve is an output end, the second valve adopts a one-way valve according to requirements, when the material is normally used, the water returns from the output end, the scheme quickly condenses and then discharges the moisture evaporated from the material, so that the time required by drying the material is greatly reduced, the structure after this embodiment of adoption is reasonable, excellent in use effect.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that the changes in the shape and principle of the present invention should be covered within the protection scope of the present invention.
