Vacuum oven

Abstract

The invention discloses a vacuum oven. Through the arrangement of a circulating air duct and a heating bag, after a heating tube group generates heat, the heat is blown to a left side plate and a right side plate through a fan, and the heat continuously reaches all positions of an inner chamber from a left inclined plate, a left straight plate, a right inclined plate and a right straight plate andthen enters the fan again from a back plate to form heat circulation, so that the heat at all positions of the inner chamber can be quickly balanced, and the problem that a door plate is difficult toheat can also be solved. The vacuum oven comprises an oven body and at least one inner chamber, and the circulating air duct and the heating bag are arranged in the inner chamber. The circulating airduct comprises the left side plate, the back plate and the right side plate, the left side plate comprises the left inclined plate and the left straight plate, and the right side plate comprises theright inclined plate and the right straight plate. The heating bag is arranged between the inner chamber of the vacuum oven and the circulating air duct, and comprises a middle partition plate and heating bag modules symmetrically arranged on the two sides of the middle partition plate.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a vacuum oven. Background technique [0002] Vacuum oven is a box-type drying equipment that dries dry materials under negative pressure conditions. The principle is: use the vacuum pump to pump air and dehumidify, so that a vacuum state is formed in the working room, the boiling point of water is lowered, and the drying speed is accelerated. [0003] In the traditional vacuum oven, the heating pipe is installed in the oven, and the heating pipe is used to heat the air to dry the items, which usually leads to excessive local temperature at the position where the heating pipe is located. Due to the large space of the industrial oven, the air heat is unevenly heated, resulting in low drying efficiency and the inability to produce high-quality products. In addition, it is generally difficult for heat to be transmitted to the door panel of the vacuum oven, which makes it difficult f...

Problems solved by technology

[0005] The invention discloses a vacuum oven. Through the arrangement of a circulating air duct and a heating package, after the heating tube group generates heat, it is blown out to the left side plate and the right side plate through a fan, and the heat is continuously transmitted from the left inclined plate, the left straight plate, and the right inclined plate. The board and the right straight board reach all positions of the inner chamber, and enter the fan again from the back board to form a heat cycle, which can quickly balance the heat of each position of the inner chamber, and can also solve the problem of difficult heating at the door panel
