Description

Technical Field

[0001] The utility model belongs to the technical field of feed production, and particularly relates to an external heater for a spiral auger conveyor. Background Art

[0002] Grease post-spraying technology has been widely used in the production and processing of various feeds to solve the problems of loss of effective ingredients and cross-infection of drugs caused by the production of pellet feed and extruded feed under high temperature, high humidity and high pressure. In actual production, when the weather is cold, the post-sprayed oil product is pre-cooled when it contacts the auger shaft, and the oil and material stick to the main shaft of the auger conveyor, and the stickiness increases, affecting the transportation; in addition, some sticky blocks will fall off during continuous transportation and enter the next process, affecting product quality. Utility Model Content

[0003] The utility model aims to provide an external heater for a spiral auger conveyor.

[0004] The utility model is realized through the following measures: an external heater for a spiral auger conveyor, characterized in that a heating port is arranged on a machine cover of the conveyor, a lower frame plate is arranged on the upper end surface of the machine cover and located at the periphery of the heating port, a heating cover is arranged above the lower frame plate, and a heating lamp is installed on the inner upper part of the heating cover.

[0005] The middle of the lower frame plate is sealed by a protective net, and the protective net is made of high temperature resistant material.

[0006] It also includes an upper frame plate parallel to the lower frame plate, the upper frame plate and the lower frame plate are fixedly connected via a rectangular cylinder, and the heating cover is slidably arranged on the upper frame plate.

[0007] A right-angle plate is fixedly arranged on the upper end surface of the upper frame-shaped plate, the openings of the two right-angle plates are arranged opposite to each other, and sliding plates sliding along the right-angle plates are arranged on the outer edges of both sides of the lower part of the heating cover.

[0008] The heating cover comprises a top plate and inclined side plates symmetrically arranged on both sides of the top plate, and the lower ends of the two inclined side plates are expanded outwards. The inclined side plates can facilitate the flow of hot air along the inclined side plates.

[0009] The sliding plate is fixed to the outer edge of the lower end of the inclined side plate.

[0010] The middle of the upper frame plate is sealed by a high temperature resistant dustproof net, and the dustproof net can reduce the entry of external dust into the conveyor.

[0011] The length of the heating cover along the main axis direction is less than the length of the heating port, and a roller is provided on the inner wall of the top plate through a bracket, and the roller is tangent to the dust screen. If the heating lamp is too long, the cost is high and it is difficult to install and maintain. By setting the heating cover to slide, the length of the heating lamp can be reduced and it can be directly slid out from one end of the right angle plate for later maintenance, which is convenient for installation and disassembly.

[0012] A plurality of top screws are provided through the horizontal plate of the right-angle plate through threaded connection, so as to fix the heating cover and avoid excessive shaking of the heating cover when the machine is running.

[0013] The heating lamp is located directly above the main shaft.

[0014] Usage: fix the lower frame plate to the periphery of the heating port by welding or bolting. Generally, the inner wall of the lower frame plate is flush with the inner wall of the heating port. Install the rectangular cylinder with a protective net and a dustproof net with the upper frame plate and the lower frame plate. Finally, slide the heating cover along one end of the right-angle plate and start the heating lamp to heat the inside of the conveyor.

[0015] The beneficial effects brought about by the technical solution provided by the embodiment of the utility model are: through an external heating lamp, the inner bin of the conveyor can be heated, the temperature around the main shaft and the machine cover can be increased, and the phenomenon of grease and material sticking together can be avoided as much as possible; the structure is simple and the manufacturing cost is low. It is applied to existing conveyors, which effectively reduces the adhesion of grease and materials and reduces the sticky blocks in the product. BRIEF DESCRIPTION OF THE DRAWINGS
