Description

A kind of Pneumatic drying device

Technical field

The utility model relates to dry materials field, specifically a kind of Pneumatic drying device.

Background technique

In Chemical Manufacture, in order to facilitate solid product storage, using with further processing, it is often necessary to pass through drying Remove hygroscopic water therein, and the type selecting of drier is one of an important factor for influencing solid product drying effect.

The material more sensitive for temperature performance, shows as viscosity at high temperature, or is easy agglomerating, largely influences Drying efficiency.Meanwhile existing gas flow dryer is mostly straight tube form, and will be straight with bend pipe (being bent in 90 degree or 180 degree) Pipe connects, and generally 14-20 meters of height, overall structure is higher and not compact, comes one to installation, checking maintenance and cleaning tape Fixed difficulty.

Utility model content

The purpose of the utility model is to overcome the deficiencies in above-mentioned background technique, provide a kind of Pneumatic drying device, the dress Setting should have the characteristics that simple and compact for structure, drying efficiency is high.

The technical solution of the utility model is:

A kind of Pneumatic drying device, the device include sequentially connected hopper, feeding mechanism, drier, cyclone separator, Sack cleaner；It is characterized by: fixing several spiral flow deflectors on the inner wall of the drier, flow deflector is along drying The axial arrangement of device, and the direction of rotation of adjacent baffle is opposite.

The drier is equipped with air inlet, feed inlet, outlet and collet, and collet is equipped with heat exchange medium import and heat exchange Media outlet.

The feeding mechanism is separately connected the outlet of hopper and the feed inlet of drier；The outlet of the drier connects rotation The import of wind separator, the lower exit port of cyclone separator connect main collector, and the top exit of cyclone separator connects pocket type Deduster import, the lower exit port auxiliary connection collector of sack cleaner.

The beneficial effects of the utility model are:

A kind of static cell-flow deflector is added inside the drier of the utility model, therefore without any machine operation portion Part, flow deflector can be broken up to pockets of particle is easy, and strengthen hot-air to the diabatic process of wet stock, shorten wet stock Drying time, improve the dry thermal efficiency, moreover it is possible to which the flow distance and wet stock and hot-air for increasing gas-solid mixing fluid exist Residence time in drier, to reduce the height of device；Therefore, the utility model have compact-sized, dry tenacity it is big, Thermal efficiency height and the high feature of utilization rate of equipment and installations.

Detailed description of the invention

Fig. 1 is the schematic view of the front view of the utility model.

Specific embodiment

Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model be not limited to Lower embodiment.

As shown in Figure 1, a kind of Pneumatic drying device, including hopper 6, feeding mechanism 7, drier 3, cyclone separator 8, bag Formula deduster 10, main collector 9, secondary collector 11.

The drier is the tubular shell placed vertically, and the bottom of drier is equipped with air inlet 4 and feed inlet 5, charging Mouth is located above air inlet, and the top of drier is equipped with outlet.Collet 2 is additionally provided on drier, the bottom of collet is equipped with heat exchange Medium import 13 and top are equipped with heat exchange media outlet 12.By the way that several spiral shapes are welded and fixed on the inner wall of the drier Flow deflector 1, flow deflector arranges that and the direction of rotation of adjacent baffle is opposite along the axis direction of drier.

The outlet of the hopper connects feeding mechanism, and feeding mechanism reconnects the feed inlet of drier, and feeding mechanism is preferred Screw conveyor.The import of the outlet connection cyclone separator of the drier, the lower exit port of cyclone separator connect main receipts Storage, the import of the top exit connection sack cleaner of cyclone separator, the lower exit port auxiliary connection of sack cleaner are collected Device.

The air inlet of hot-air input drier by the preheating of external heater, feeding mechanism is by the wet stock in hopper Input the feed inlet of drier；In drier, the gas-solid mixing fluid that hot-air and wet stock are formed flows from lower to upper, leads Flow is split gas-solid mixing fluid, rotates, and the interface for causing gas-solid mixing fluid strong updates, and generates efficient alternate Transmitting, so that the moisture of wet stock be vaporized；From dryer export flow out gas-solid mixing fluid enter in cyclone separator into Row separation, the solid after separation are collected by main collector, and the dusty gas after separation enters sack cleaner and is filtered, by mistake The solid particle of filter is collected by secondary collector, and purified gas enters external vent gas treatment tower processing.

Heat exchange medium used in collet can be selected according to the concrete condition of material.For those to temperature-insensitive Material, heat exchange medium can select hot-air or hot water, and enhancing collet is to the radiant heat transfer of drier and then promotes dry effect Rate.For those thermally sensitive materials, material may soften as viscous fluid state and be sticked to dry in the drying process Dry device inner cavity top, is easy to influence drying effect, and the medium that exchanges heat at this time can select cooling water, so that this kind of situation be avoided to send out It is raw.
