Abstract

The utility model relates to a horizontal type screw thread pipe bundle drier, a steam hollow-core shaft is communicated with a screw thread pipe by an air-collecting sealing head, the screw thread pipe is fixed through a pipe plate of a pipe bundle, and the other end of the screw thread pipe is communicated with a valve gate by the air-collecting sealing head and the steam hollow-core shaft. High temperature steam penetrates in the screw thread pipe and conducts heat through the pipe wall to carry out heating and drying to material, an air heater is also arranged on the drier, and the air heater is loaded into a hot air pipeline to carry out doubly heating to the material through a blower. The utility model uses the screw thread pipe instead of a plain-pipe type pipe bundle, so the heat transferring effect is intensified. The utility model has the advantages of enhancing heat transferring effectively and improving evaporation capacity; under the premise of same evaporative capacity, the utility model solves the defects that the volume and the weight of a pipe bundle are large, and wet sticky material is attached to the pipe bundle and a main machine of the drier.

Description

Horizontal screw thread pipe bundle drier

The utility model relate to heat, dry technology, particularly a kind of light industry, feedstuff industry material of being used for carries out dry horizontal screw thread pipe bundle drier.

Present employed contact pipe bundle drier is widely used in starch, brew alcoholic beverages and feedstuff industry, because these factory's forward large scale developments, but large-scale pipe bundle drier exists the manufacturing process complexity, cost height, bulky shortcoming, give and make, transport, install and overhaul and all bring a lot of difficulties, because the heating tube of pipe bundle drier is a light-pipe structure,, reduced drying capacity in addition to various moist material bad adaptability.

The purpose of this utility model provides and a kind ofly replaces tube bank light pipe heating element heater with the enhanced heat transfer component screwed pipe, and with the horizontal screw thread pipe bundle drier of high temperature air dual-heated.

The utility model is to realize like this, it comprises casing, steam air-cored axis, tube bank tube sheet charging aperture, the pusher shovel, the gas collection end socket, exhaust outlet, hot-air duct, main frame insulation cladding discharge gate, bearing block, transmission mechanism, air heater, blower fan and separator, it is characterized in that steam air-cored axis is connected with screwed pipe by the gas collection end socket, screwed pipe is fixing by the tube bank tube sheet, and the other end of screwed pipe is by the gas collection end socket, steam air-cored axis is connected with valve, and high-temperature vapour passes in screwed pipe and by tube wall heat conduction material carried out heat drying, also be provided with air heater on drying machine, this air heater is sent into hot-air duct by blower fan material is carried out dual-heated.

The utility model is owing to replace the tube bank of light pipe formula with screwed pipe, strengthened heat-transfer effect, also owing to outside screwed pipe, added high-temperature hot air as second thermal source, material in the drying machine heated blow, so effective augmentation of heat transfer of energy, improve evaporability, under identical evaporation capacity prerequisite, solved main frame and the big shortcoming of tube bank volume and weight that wet adhesive material is stuck with paste tube bank and drying machine.

Below in conjunction with accompanying drawing the utility model is done further description,

Fig. 1 is the structural representation of horizontal screw thread pipe bundle drier,

Fig. 2 is the electrical schematic diagram of Fig. 1,

Fig. 3 be Fig. 1 along A--A to profile,

As Fig. 1--shown in 3, this horizontal screw thread pipe bundle drier comprises casing 15, steam air-cored axis 1, tube bank tube sheet 2, charging aperture 3, pusher shovel 4, gas collection end socket 5, exhaust outlet 7, hot-air duct 8, main frame insulation cladding 9, discharge gate 10, bearing block 11, transmission mechanism 12, air heater 13 and 18,

blower fan

14,17,19 and separator 16, steam air-cored axis 1 is connected with screwed pipe 6 by gas collection end socket 5, screwed pipe 6 is fixing by tube bank tube sheet 2, the other end of screwed pipe 6 is by the gas collection end socket, steam air-cored axis is connected with valve, high-temperature vapour passes in screwed pipe 6 and by tube wall heat conduction material is carried out heat drying, on drying machine, also be provided with air heater 13,18, this air heater 13,18 by

blower fan

14,19 send into 8 pairs of materials of hot-air duct carries out dual-heated, operation principle is that high temperature air is introduced into gas collection end socket 5 by steam air-cored axis 1, enter screwed pipe 6 inner chambers, the condensate water of cooling is by the end socket of the other end, air-cored axis's 1 valve is discharged drying machine, and wet stock is entered in the drying machine by charging aperture, and is middle through heat conduction heating and air heater 13 at tube bank screwed pipe 6, the high temperature air of 18 heating is at

blower fan

4,19 blast and simultaneously material are carried out convection current in the drier host machine and implement dual composite drying, dry material slowly reach under pusher shovel 4 and tube bank turning effort, outside discharge gate 10 discharge machines, the air that is cooled of the moisture in the material carries by air-introduced machine 17 shedders and enters separator 16 outward, and the material that waste vapour is carried secretly from last discharge returns in the drying machine from the bottom.
