Abstract

The invention relates to electrothermal air-blowing drying equipment with the good drying effect. The electrothermal air-blowing drying equipment comprises a cabinet, cabinet doors, a safety lock, a drying mechanism and a control mechanism; the drying mechanism comprises a rotating assembly and an air blower; the rotating assembly comprises a driving unit and a transmission unit; and the transmission unit comprises a notch disc, a rotating arm, a cylindrical pin, a groove wheel, a pin shaft, a rotating shaft and a rotating disc. A control system of the electrothermal air-blowing drying equipment with the good drying effect comprises a central control module and a work power supply module. In the electrothermal air-blowing drying equipment with the good drying effect and the control system thereof, through the drying mechanism, reliable and uniform heating drying for the circumferential direction of products is achieved; in addition, MCU programming is replaced, and thus the stability and reliability of operation of the equipment are improved; and in a work power supply circuit, a field effect pipe serves as an adjusting pipe, a circuit 1A can be expanded, during a transitory high load of the electrothermal air-blowing drying equipment, transitory high current output can also be conducted, and the practicability of the electrothermal air-blowing drying equipment is improved.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to an electric blast drying equipment with good drying effect and a control system thereof. Background technique [0002] Electric blast drying oven, also known as "oven", as the name suggests, adopts electric heating to carry out blast circulation drying test, which is divided into two types: 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, so that the atmospheric pressure in the box is lower than normal pressure, so that the product can be tested in a very clean state. It is a commonly used instrument and equipment, mainly used to dry samples. Provide the temperature environment required for the experiment. Drying ovens are used in various industries such as chemical industry, medicine, foundry, automobile, food, machinery a...

Problems solved by technology

However, the control of the motor requires the MCU to be programmed and controlled, which increases the workload of the MCU, and in the process of programming the MCU, BUGs often inevitably appear, which reduces the reliability of the drying equipment; not only In this way, during the working process of the drying equipment, the working power supply circuit is required to provide a stable working voltage. When the equipment temporarily increases the load, the working power supply circuit needs to increase the output current to improve the driving ability, but this requires power consumption Larger integrated circuits are provided, which affects the operating economic ratio of the equipment and reduces its practical value
