Abstract
The invention discloses a heating box with low thermal loss. A rack is of a frame-type structure sealed on four sides, and a seal plate is fixedly connected with a through hole at the right side of the rack. An outlet box is fixedly connected with the side of the seal plate. An air outlet is inserted into the inner cavity of the rack through a through hole at the front side of the rack and fixedly connected with a connection plate on the rack. A heating pipe is fixed in the cavity of the air outlet, and the binding post of the heating pipe is located in a cavity formed by the rack and the air outlet. A filter net is arranged between the rack and the air outlet. The air outlet is a tapered connecting pipe of which the two sides are communicated, the air outlet is further fixed with a temperature probe, and the probing rod of the temperature probe is inserted into the inner cavity of the air outlet pipe.
Description
Technical field
The present invention relates to a kind of heated-air drying equipment, the heating cabinet in the hot air delivery system of especially using in PE film crushing washing industry, belong to the plant equipment field.
Background technology
The structure of heating cabinet commonly used is in PE film bottle crushing washing industry at present, frame (1) is the frame type structure communicated before and after the sealing of four sides, in the interlayer of frame (1), be filled with heat-preservation cotton (1-1), in the cavity of frame (1), be fixed with heating tube (2), the binding post of heating tube (2) stretches in the cavity of frame (1) top.Shrouding (1-3) is fixedly connected on the top of frame (1).Outlet box (1-2) is fixedly connected on the square tube of frame side.On the passage communicated in the front and back of frame (1), be separately installed with screen pack (3) and air outlet (4), air outlet (4) is the pipeline that the two sides of a taper communicates, on air outlet (4), also be fixed with temp probe (5), the feeler of temp probe (5) stretches into the inner chamber of air outlet.Operation principle is, connects blower fan on air outlet (4), and then air enters air outlet (4) from screen pack (3) by heating tube (2) heating and transferred out by blower fan.The heating cabinet of said structure form is due to the binding post of heating tube (2) in an enclosure space, and the high-temperature that heating tube (2) produces accumulates in enclosure space, and the binding post and the wire that cause connecting heating tube (2) are burned soon.And heat can a large amount of being transmitted on frame cause thermal losses.
Summary of the invention
Technical problem to be solved by this invention is: binding post and wire capacity for existing heating cabinet heating tube are burned, heat is transmitted on frame the shortcoming that causes thermal losses, propose a kind ofly can effectively improve heating tube and wire service life, reduce the heating cabinet of thermal losses.
For achieving the above object, the technical solution used in the present invention is: frame is circumferential closed frame type structure, and shrouding is fixedly connected on the through hole, right side of frame.Outlet box is fixedly connected on the side of shrouding.Air outlet is from the inner chamber that inserts frame the front side through hole of frame, and is fixedly connected with the connecting plate on frame.In the cavity of air outlet, be fixed with heating tube, the binding post of heating tube is in the cavity of frame and air outlet formation.Between frame and air outlet, screen pack is installed.Air port is the tube connector that the two sides of a taper communicates, and on air outlet, also is fixed with the temperature control head, and the feeler of temperature control head stretches in the inner chamber of outlet.
Operation principle is, connects blower fan at air outlet, and air, from screen pack, suck the passage that flows into frame and air outlet formation, then heats and then enters air outlet and by blower fan, transferred out by heating tube.In the cavity that frame and air outlet form, the air that the high temperature on the heating tube binding post is flowed is taken away due to the binding post of heating tube, and this just makes the binding post of heating tube and wire be not easy to be burned.And, because the cold air sucked is first through frame and the passage that air outlet forms, between air outlet and frame, be to fix by very little connecting plate, so just make the heat can be by a large amount of not being transmitted on frame.
The invention has the beneficial effects as follows: heating tube and wire long service life, the heating cabinet thermal losses is low, energy-conservation.
