a vacuum oven

Abstract

The invention discloses a vacuum oven. Through the arrangement of a circulating air duct and a heating pack, after the heating pipe group generates heat, it is blown out to the left and right side plates through a fan, and the heat continuously flows from the left inclined plate, the left straight plate and the right inclined plate. The plate and the right straight plate reach various positions in the inner chamber, and enter the fan again from the back plate to form a heat cycle, which can quickly equalize the heat in each position of the inner chamber, and can also solve the problem of difficult heating at the door panel. The vacuum oven of the present invention includes an oven main body and at least one inner chamber, wherein a circulating air duct and a heating pack are arranged in the inner chamber; the circulating air duct includes a left side panel, a back panel and a right side panel, and the left side panel is The plate includes a left inclined plate and a left straight plate, and the right plate includes a right inclined plate and a right straight plate; the heating pack is arranged between the inner chamber of the vacuum oven and the circulating air duct, including the middle part of the partition plate and the The heating pack module is symmetrically arranged on both sides of the middle part of the partition.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a vacuum oven. Background technique [0002] A vacuum oven is a box-type drying equipment that dries dry materials under negative pressure conditions. The principle is: use a vacuum pump to extract air and dehumidify, so that a vacuum state is formed in the working room, the boiling point of water is reduced, and the drying speed is accelerated. [0003] In a traditional vacuum oven, the heating tube is set in the oven, and the heating tube is used to heat the air to dry the items, which usually causes the local temperature of the location where the heating tube is located to be too high. Due to the large space of the industrial oven and the uneven heating of the air, the drying efficiency is not high, and excellent products cannot be produced. In addition, it is generally difficult to transfer heat to the door panel of the vacuum oven, which makes it difficult for materials clo...

[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
