Dual-drying-chamber hot air circulating drying box

Abstract

The invention discloses a hot air circulation oven with double drying chambers, which comprises a box body, the box body is provided with two drying chambers, a downflow duct is arranged between the two drying chambers, and a heater is arranged in the downflow duct. A blower is provided on the top of the lower air passage; an upper air passage is provided on both sides of each drying chamber, and an induced draft fan is provided on the top of the upper air passage; a temperature sensor is also provided inside the box, and the temperature sensor is connected to a solenoid valve and an alarm; There are air supply motors on both sides of the box, and the blower and the induced draft fan are connected to the air supply motor through a transmission shaft; a thermostat is provided on the box, and the thermostat is connected to a PLC controller on one side of the box, and the PLC The controller is also connected to control various electrical components including the heater, the blower, the induced draft fan and the blower motor. The double drying room design is also equipped with a matching double circulation system, so as to overcome the problem of uneven drying effect caused by the large oven body; when the temperature control fails, the staff can be reminded.

Description

technical field [0001] The invention relates to drying mechanical equipment, in particular to a hot air circulation oven with double drying chambers. Background technique [0002] The hot air circulation oven is mainly used for heating and curing, drying and dehydration of materials in industries such as medicine, chemical industry, food, agricultural and sideline products, aquatic products, and light industry. With the advancement of science and technology and the development of the times, people's requirements for heat treatment of materials are constantly improving. Hot air circulation ovens are generally equipped with a heating system and a hot air circulation system. The hot air circulation system supplies air to circulate the hot air in the oven to ensure uniform indoor temperature. sex.

Problems solved by technology

Some single-chamber ovens, because there is a drying chamber and its supporting circulation system in the same cabinet, so when the drying chamber is larger or the drying of the dried object is more difficult, it may not be able to dry The balance of the drying temperature of the product will affect the drying effect; at the same time, the control settings of each component of the oven, such as each process is manually set, is time-consuming and laborious, and is prone to operational errors. Microprocessor joint control can be used. Automatic control is achieved by means of automatic control; while in some process operations related to production safety, such as automatic control by microprocessors, when control failure occurs, life and property safety will be endangered.
