Electric heating air blow constant-temperature drying box

Abstract

The invention relates to the technical field of constant temperature drying boxes, and discloses an electric blast constant temperature drying box, comprising a drying box, a chassis is fixedly installed at the bottom of the drying box, a motor is fixedly installed at the bottom of the inner cavity of the box, and the motor A driving wheel is fixedly fitted on the output shaft of the driving wheel, the outer teeth of the driving wheel mesh with the driven wheel, the middle part of the driven wheel is fixedly fitted with a rotating rod, and one end of the rotating rod is fixedly fitted with a The rotating bearing, one end of the rotating rod passes through the outside of the cabinet and extends to the inside of the drying box. The electric blast constant temperature drying oven, through the cooperation of the driving wheel and the passive theory, makes the rotating rod drive the tray to rotate, and uses the cooperation of the sliding block and the guide rail to make the driving plate drive the baffle Ⅰ to rotate, preventing the temperature of the drying box from spreading evenly. Avoid some places where the temperature is high and some places where the temperature is low, which will affect the uneven heating of objects.

Description

technical field [0001] The invention relates to the technical field of a constant temperature drying oven, in particular to an electric blast constant temperature drying oven. Background technique [0002] The electric heating constant temperature blast drying oven is used for drying, baking, melting wax, and sterilization in industrial and mining enterprises, laboratories, scientific research units, etc. The electric heating blast drying oven is also called "oven". It is divided into blast drying and vacuum drying. Blast drying is to blow hot air through the circulating fan to ensure the temperature balance in the box. Vacuum drying is to use a vacuum pump to extract the air in the box to make the atmospheric pressure in the box lower than normal pressure. The product is tested in a very clean state. [0003] The existing known electric blast constant temperature drying oven can achieve the function of constant temperature, but when most electric blast constant temperature...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electric blast constant temperature drying box, which has the advantages of fast heating and uniform heating, and solves the problem that most of the electric blast constant temperature drying boxes are dry in the box when they are in use. Uneven drying, high temperature in some places and low temperature in some places, resulting in uneven heating of the object, causing the object to fail to dry, and affecting the later experiments
