Abstract
The invention discloses an improved low-temperature vacuum drying oven. The improved low-temperature vacuum drying oven comprises an oven body, drying trays and at least one layer of drying rack, the inner top of the top of the oven box is semi-elliptical, the inner bottom of the bottom of the oven body is concave, and the concave portion of the inner bottom is provided with a drainage pipe; the drying racks are arranged inside the oven body, both the upper end and the lower end of the drying racks are provided with a steam pipe, the connector opening of each steam pipe is provided with a quick connector, and the drying trays are arranged on the drying racks. The improved low-temperature vacuum drying oven improves vacuum-pumping efficiency, avoids dead angles, solves the problem that materials at the top layer is not easy to dry, improves drying efficiency, solves the problems that materials are easy to be scorched at the contact position of the bottom of the drying tray and a heat dissipating coil pipe, improves drying efficiency on the whole and reduces drying energy loss.
Description
Technical field
The present invention relates to the drying box technical field, be specifically related to a kind of improved low-temperature vacuum drying case.
Background technology
So-called vacuum drying is exactly that the material will be dried is in the heat drying carried out under vacuum condition, it is to utilize the vavuum pump dehumidifier of bleeding, make in operating room to form vacuum state, reduce the boiling point of water, accelerate rate of drying, can at a lower temperature, obtain higher rate of drying, Btu utilization is abundant, without any impurity, sneaks in dry run.This drying box is widely used in the industries such as medicine, food, light industry, chemical industry and does low temperature drying, has dry goods speed fast, pollutes littlely, can the inherent quality of the article that are dried not damaged.Existing drying box top is square, leaves dead angle, is difficult for drying so that top one deck is equipped with the drip pan of material; Ponding constantly appears in bottom half, affects drying efficiency; Drip pan and heat dissipation plate close contact, cause the drip pan bottom to occur easily that with the radiator coil tube contact position material is by the phenomenon of adustion.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, a kind of improved low-temperature vacuum drying case is provided, improved and vacuumized efficiency, avoided the appearance at dead angle, solved top one deck material and be difficult for the phenomenon of drying.
Technical scheme: a kind of improved low-temperature vacuum drying case of the present invention, comprise casing, drip pan and one deck shelf at least, the interior top at described casing top is half elliptic, and the interior end of bottom is spill, and concave bottom of the interior end connects blow-off pipe is set; Described shelf is arranged at described box house, and the upper and lower two ends of described shelf connect respectively steam pipe is set, and described steam pipe interface is equipped with snap joint, and described drip pan is arranged on described shelf.
Being further defined to of technical solution of the present invention, described Nei Ding top is connected with vacuum-pumping tube, vacuum-pumping tube access surge tank.
Further, the positive middle and upper part of described casing and middle and lower part configuration front-view mirror, and at casing back middle position configuration rearview mirror.
Further, described casing comprises inner and outer wall, described inner and outer wall intermediate arrangement heat-insulation layer.
Further, described heat-insulation layer arranges the liner channel-section steel, and described liner channel-section steel is the well word and arranges.
Further, described shelf layering is distributed in drying box, from top to bottom S-type coil pipe.
Further, described shelf bottom device stainless steel steamboat.
Further, the distance between aforesaid drip pan and shelf is 8-10mm.
A kind of improved low-temperature vacuum drying case provided by the invention, the interior top of casing of adopting the semiellipse type, improved and vacuumized efficiency, avoided the appearance at dead angle, solved top one deck material and be difficult for the phenomenon of drying; The present invention has avoided the bottom half seeping phenomenon, improves drying efficiency; Avoided the drip pan bottom to occur easily that with the radiator coil tube contact position material is by the phenomenon of adustion; Improve on the whole drying efficiency, reduce and dry energy loss.
The accompanying drawing explanation
Fig. 1 is the structural representation of low-temperature vacuum drying case provided by the invention;
Fig. 2 is the side view of low-temperature vacuum drying case provided by the invention;
Fig. 3 is the cutaway view of low-temperature vacuum drying case provided by the invention.
The specific embodiment
Below technical solution of the present invention is elaborated, but protection scope of the present invention is not limited to described embodiment.
Embodiment:As shown in Figure 1, as shown in Figure 2, cutaway view as shown in Figure 3, comprises casing 1, shelf 8 and drip pan 7 to side view for low-temperature vacuum drying case of the present invention, its structural representation.
Casing 1 is of a size of 1.5m * 1.5m * 1.5m, the positive middle and upper part of casing 1 and middle and lower part configuration front-view mirror 3, and at casing 1 back middle position configuration rearview mirror 4, the inwall of casing 1 and outer wall intermediate arrangement heat-insulation layer, insulation bed thickness 80mm, insulation material filling aluminosilicate refractory fiber cotton, the liner reinforcement is the 8# channel-section steel, become intersecting parallels to make, the interior top 6 at casing 1 top is half elliptic, 6 tops, interior top are connected with vacuum-pumping tube 2, vacuum-pumping tube 2 access surge tanks 11, the interior end 9 of carrying out the vacuum pumping bottom, be spill, concave bottom of the interior ends 9 is connected with blow-off pipe 10, on blow-off pipe 10, seal ball-valve is installed.
The interior shelf 8 that arranges 8 layers of casing 1, the shelf material is the 1Cr18Ni9Ti stainless steel tube, be that S type coil pipe is made from top to bottom, supervisor is φ 22 * 2, φ 25 * 2, auxiliary pipe is φ 32 * 3, freely, snap joint all is equipped with in shelf 8 steam pipes and casing 1 junction for 4 stainless steel steamboats of shelf 8 bottom device, activity in orbit.
Article to be dried evenly are positioned in drip pan 7, close chamber door and sewage draining exit 10 valves of casing 1, carry out vacuum pumping, the interior air of casing 1 and moisture are extracted casing out by vacuum-pumping tube 2, and condensing drip is dropped in surge tank 11, when casing 1 internal pressure be reduced to-below 0.098mpa after, stop vacuum pumping, and keep pressure.
