Abstract

The utility model relates to a hot air type pipe bundle dryer used for dry materials. The dryer has the following structure: a tube pipe bundle dryer is arranged in a casing; two ends of the dryer are rotationally connected with a supporting seat; a driving mechanism is connected with one end of the dryer through a transmission mechanism; a material inlet and a material outlet are formed on the casing; a feeder is connected with the material inlet; an air exhaust tube is connected with the upper part of the casing; and one end of the casing is provided with an air heating furnace blowing hot air into the dryer. The direct flame type air heating furnace is arranged and connected, so that the pipe bundle dryer enables the coal-fired hot air to flow directly into the tube bundle of the dryer, the tube wall is heated up, and materials are dried up. The coal-fired hot air furnace has the advantages that the utilization rate of the fuel is high, the operation is simple, the energy is saved, and the price is low, therefore, a large amount of equipment investment can be saved.

Description

A kind of hot air type pipe bundle drier

Technical field

The utility model relates to a kind of material drying device, specifically a kind of hot air type pipe bundle drier.

Background technology

Mostly existing pipe bundle drier is to adopt steam or heat conduction wet goods medium to come the tubulation in the heat drier to restrain.Mostly the structure of this class pipe bundle drier is to be equipped with tubulation bundled tube drier in casing, the two ends of drier are rotatably connected on the supporting seat, and driving mechanism drives whole drier rotation by transmission mechanism; Charging aperture place at casing is connected to loader, constantly to carry moist material in casing; Be connected to aiutage on casing top, to get rid of the steam in the casing; Steam boiler or heat-conducting oil furnace be delivering vapor or conduction oil in drier, with the tube bank of the tubulation in the heat drier, makes material be heated oven dry.This class pipe bundle drier is because of relatively large equipment such as needs adapted steam boiler or heat-conducting oil furnaces, and investment is big, and energy resource consumption is big, operates more loaded down with trivial details.

The utility model content

The purpose of this utility model just provides a kind of hot air type pipe bundle drier, to reduce investment, simplifies the operation energy savings.

The utility model is achieved in that a kind of hot air type pipe bundle drier, tubulation bundled tube drier is housed in casing, the two ends of drier are rotatably connected on the supporting seat, driving mechanism joins by an end of transmission mechanism and drier, on casing, have charging aperture and discharging opening, the place is connected to loader at charging aperture, and aiutage is connected on the top of casing, is provided with the hot-blast stove that is blown into hot blast to drier at an end of casing.The flue gas of hot-blast stove can be discharged by blower fan or chimney.

The utility model is by connecting the hot-blast stove of straight fiery type, makes coal hot-air directly enter in the tubulation tube bank in the drier heating tube wall, oven dry material.This coal-fired hot-blast stove fuel availability height, easy and simple to handle, save the energy, and price is very low, can save a large amount of equipment investments.

The utility model also can be at the air-introduced machine of other end setting exhausting from drier of casing on the basis of said structure.By air-introduced machine being set in the drier rear end, can guide the hot blast in the drying tube tube bank well, whole tube bank is heated evenly, thereby improves the heat drying process of material, improve dry mass.

The utility model also can be realized like this: drier is designed to two-layer pipe by the drying tube of hot-blast stove one end.This is owing to after adopting straight fiery type hot-blast stove, and is higher in the temperature of drier air intake, easily material heat is stuck with paste.After adopting two-layer pipe, just can reduce the temperature of outer wall effectively, reach the purpose of defence thickener.Through repetition test, the bimetallic tube part is advisable to account for 20-30% of drying tube total length.

The utility model also can be respectively arranged with the umbrella end socket at the two ends of drier, the external blast pipe of end socket, and another end socket picks out airduct.So just can seal the two ends of drier by end socket, and with the rotation central siphon of two airducts as drier.Since be with airduct as rotating central siphon, and the caliber of airduct is relatively thicker, supports support rollers so be provided with at least 4 at the root of each airduct, to guarantee the safe operation of equipment.

On the basis of said structure, the end socket inboard that the utility model is preferably in external blast pipe is provided with a split-wind plate again.Hot blast in the hot-blast stove directly enters drier by blast pipe, and under the effect of split-wind plate, hot blast just can be divided to advance in each drying tube equably, realizes evenly heating.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, this novel hot air type pipe bundle drier has one and the essentially identical casing 1 of tradition tube bank drier structure, and casing can be divided into upper casing and lower casing two parts.In casing 1 drier is housed, drier is a tubulation bundled tube structure, and tube bank is connected to form by drying tube 2 and tube sheet 16, is welded with angle steel 13 at the excircle of tube sheet, is welded with stock guide 14 and lifting blade 17 on angle steel 13.The two ends of drier are rotatably connected on the supporting seat 6, and driving mechanism 18 drives the drier rotation by transmission mechanism.Have some air vents 15 on casing 1 top, so that air enters, steam is discharged by aiutage 4, and aiutage 4 is connected on the top of casing 1.Charging aperture place at casing 1 right-hand member is connected to agitator type loader 3, so that material is sent in the casing 1 continuously.Hot-blast stove 5 is located at the right-hand member of casing 1, and air-introduced machine 7 is connected on the left end of casing 1.

Driving mechanism 18 in this device is made up of motor and speed reducer, and transmission mechanism can be chain drive or gear drive.Driving mechanism drags whole tube bank rotation by transmission mechanism.After material is added by loader 3, by the peripheral stock guide 14 of tube bank and lifting blade 17 material is constantly kicked up, moved forward, in this process, material is by heat drying constantly.At last, the material of having dried is drawn off from the discharging opening of casing 1 left end, and water vapour discharged automatically by aiutage 4.Finish whole dry run thus.

The right-hand member of the drying tube 2 in this device in the drier is designed to two-layer pipe, and bimetallic tube partly accounts for 20-30% of drying tube total length.In addition, be connected to umbrella end socket 8 respectively at the two ends of drier, the end socket 8 external blast pipes 9 of right-hand member, the end socket of left end picks out airduct 10.Root at each airduct is provided with 4 support support rollers 12.In the inboard of right-hand member end socket 8 split-wind plate 11 relative with blast pipe 9 internal orifices is housed also, so that hot blast is evenly distributed in each drying tube.
