Electric heating constant-temperature air blowing drying box

Abstract

The invention discloses an electric heating constant-temperature air blowing drying box. The electric heating constant-temperature air blowing drying box comprises a drying box body, a machine frame, a circulation pipe arranged on the drying box body, a box door arranged on the drying box body, two fixing portions symmetrically arranged on the inner wall of the drying box body, and a supporting plate arranged inside the drying box body, wherein the drying box body is arranged on the machine frame; a heater is arranged on the machine frame, and the output end of the heater extends to the bottom inside the drying box body and is provided with a heating iron wire ring; two first rotary shafts and two second rotary shafts are symmetrically arranged on two sides of the supporting plate; the two first rotary shafts are both provided with large roller wheels; the two second rotary shafts are both provided with small roller wheels; the fixing portions are provided with first roller grooves matched with the large roller wheels and further provided with second roller grooves matched with the small roller wheels; the upper portion of the supporting plate is provided with a fixing seat; and the circulation pipe is connected with an air blower. The electric heating constant-temperature air blowing drying box saves energy, is uniform in internal temperature, and is controllable in temperature.

Description

technical field [0001] The invention relates to an electric heating constant temperature blast drying oven. Background technique [0002] The electric constant temperature blast drying oven is one of the most widely used laboratory equipment in various laboratories. It is the main tool used for precision constant temperature and auxiliary heating in colleges, universities, industrial and mining enterprises, and scientific research units; the traditional drying oven is generally They are all controlled manually, and the control dial is at the bottom of the drying box. It is very inconvenient to squat down when operating. In addition, the internal heating device is installed at the bottom of the inner tank, and the heating is uneven, which causes the side wall of the inner tank to be heated. Slower, the temperature at the bottom is higher and the temperature at the upper part is lower. Similarly, the heat dissipation is uneven, the internal temperature of the inner tank is not...

It is the main tool used for precision constant temperature and auxiliary heating in colleges, universities, industrial and mining enterprises, and scientific research units; the traditional drying oven is generally They are all controlled manually, and the control dial is at the bottom of the drying box. It is very inconvenient to squat down when operating. In addition, the internal heating device is installed at the bottom of the inner tank, and the heating is uneven, which causes the side wall of the inner tank to be heated. Slower, the temperature at the bottom is higher and the temperature at the upper part is lower. Similarly, the heat dissipation is uneven, the internal temperature of the inner tank is not easy to control, and it is inconvenient to take the test object, which will bring losses to the user.
