Description

Blast circulation heating vacuum oven

Technical Field

The utility model relates to a general mechanical equipment makes technical field, especially relates to a blast air circulation heating vacuum oven.

Background

Lithium cell electrolyte is the organic matter that does not contain the hydrone, and the existence of water has very big harm to the battery, can cause the battery to generate heat and explode, consequently annotate liquid and seal at the battery and must pass through the vacuum baking before, and traditional vacuum oven is through installing the heating tube around the oven and generate heat the contact through the box with heat transfer inside the box, can lead to the box to generate heat inhomogeneous and the energy consumption increase like this.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defects in the prior art, the utility model provides a blast circulation heating vacuum oven.

The technical scheme is as follows: in order to realize the above purpose, the utility model discloses a blast air circulation heating vacuum oven is equipped with the vacuum oven, be equipped with the oven in the vacuum oven, the oven rear side is equipped with the valve, be equipped with the box in the oven, be equipped with circulation heating mechanism in the oven, be equipped with the air-blower in the circulation heating mechanism, the air-blower is connected with the box that generates heat, box one side of generating heat is equipped with out the tuber pipe, the box outside all is equipped with a plurality of fixed strip, box both sides fixed strip and the inboard contactless of oven, both sides fixed strip and the inboard contact of oven about the box, be equipped with temperature probe on the box, circulation heating mechanism adds hot gas in oven inner loop.

Furthermore, a heating tube support is arranged in the heating box body, and a heating tube is mounted on the heating tube support.

Furthermore, a connecting block is arranged on the rear side of the box body.

Furthermore, the circulating heating mechanism is fixedly arranged on the connecting block.

Further, when the temperature of the gas in the oven is too high, the rear side valve of the oven is opened.

The utility model has the advantages that:

the heat that produces the heating tube through the air-blower blows hot-blast to the oven outside through going out the tuber pipe, the heat will be through clearance distance space between the fixed strip with heat transfer around the box, oven outlying air is by one advance one of air-blower and the heat drive circulation that the heating tube circulation produced, make the more even transmission of heat around the box, make the temperature around the box more balanced, when temperature probe discovery gas temperature was too high, the valve will be opened, help temperature regulation and heat dissipation.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

An embodiment, as shown in fig. 1 to 5, a forced air circulation heating vacuum oven is provided with a vacuum oven 1, an oven 2 is arranged in the vacuum oven 1, a circulation heating mechanism 3 for heating the oven 2 is arranged in the oven 2, an air blower 4 is arranged in the circulation heating mechanism 3, the air blower 4 is connected with a heating box body 5, the heating box body 5 is connected with an air outlet pipe 10, a heating pipe 6 is arranged in the heating box body 5, a box body 7 is arranged in the oven 2, a connecting square block 8 is arranged on the rear side of the box body 7, the circulation heating mechanism 3 is fixedly mounted on the connecting square block 8, a plurality of fixing strips 9 are arranged on the outer side of the box body, a parallel automatic door is mounted on one side of the oven 1 and used for sealing the oven 2 and opening and closing the oven door 2, the fixing strips 9 on the two sides of the box body 7 are not in contact with the inner side of the oven 2, and the fixing strips 9 on the upper side and the lower side of the box body 7 are in contact with the inner sides.

The operation principle of the blast circulation heating vacuum oven is as follows:

oven 2 goes up parallel automatically-controlled door and opens, put into box 7 with the material inside, the automatically-controlled door is closed, box 7 directly falls to half vacuum state, circulation heating mechanism 3 begins work this moment, valve 12 closes, heating tube 6 work in the box 5 generates heat, the air-blower 4 of box 5 one side of generating heat blows hot-blast to the box 7 outside through going out the tuber pipe with the heat that heating tube 6 produced, the heat will be through clearance distance space between fixed strip 9 around with heat transfer to the box, box 7 outlying gas is gone into one by air-blower 4 and is gone out and the heat that the heating tube circulation produced at oven 2 inner loop, when temperature probe 11 detects oven 2 internal temperature too high, valve 12 will open the thermal discharge of help.

The above is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
