Heating and drying oven capable of conveniently taking and placing experimental vessel

Abstract

The invention discloses a heating and drying oven capable of conveniently taking and placing experimental vessel. The heating and drying oven comprises a drying oven body and a control box, wherein abottom plate is arranged on the inner part of the drying oven body; a rotary disc is arranged on the center of the upper surface of the bottom plate; the bottom of the rotary disc is fixedly equippedwith a rotary shaft; a drive motor is arranged in a cavity between the bottom plate and the lower side surface of the drying oven body; the drive motor is connected with a rotary shaft; the upper partof the rotary disc is connected with a rotary frame; a plurality of bumps are arranged on the rotary disc; the bottom of the rotary frame is equipped with a plurality of grooves which are adaptive tothe bumps; the rotary frame is embedded into the upper part of the rotary disc through the grooves; a plurality of fixed rings are uniformly welded on a vertical bracket of the rotary frame; fixed blocks are arranged on the bottom of a vessel placing frame; and the fixed blocks are inserted into the fixed rings in a penetrating mode, so that detachable connecting between the vessel placing frameand the rotary frame is realized. The rotary frame rotates for rotating the vessel on the innermost layer or a blank position of the vessel placing frame to the opening of the drying oven, so that thevessel is conveniently taken out or placed in, and therefore, scald on an operator is avoided.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a heating and drying oven which is convenient for taking and placing experimental vessels. Background technique [0002] The heating drying oven is a commonly used laboratory instrument and equipment, which uses electric heating to dry the experimental utensils. Sometimes because there are many utensils stored in the drying box, and the utensils used are placed near the innermost layer of the drying box, it is very inconvenient to take out the utensils. If the utensils near the innermost layer are directly reached by hand, it is easy to burn the operation If the heating power is turned off and the required utensils are taken out after the drying box cools down, not only there is a long cooling time waiting, but also the remaining utensils in the drying box need to be reheated, which increases the power consumption. If the outer layer of the drying box has been filled with utensil...
