Abstract

The utility model relates to the stirrer of a drier for materials in paste form. The barrel bottom of a vertical stirring barrel forms a cone shape, and the bottom diameter is less than the barrel diameter. The exterior of the barrel is surrounded with a hot blast chamber. The barrel bottom forms an air inlet. Impeller vanes and stirring vanes are arranged on a rotating shaft. The surrounding periphery of the stirring barrel wall is provided with a plurality of guide perforations. The paste form material can be continuously pushed into the stirring barrel and cut, impacted, stirred with the hot blast for carrying out the heat exchange. The utility model is suitable for the mining industry, the food industry, the chemical industry to process paste form wet materials.

Description

Stirrer of drier for paste-shape materials

The utility model relates to agitator, particularly a kind of agitator that is applicable to the oven dry of paste wet stock.

The wet stock of paste, as the wet mineral powder of the sticky attitude that grinds with wet ball mill, and plaster material etc. in the pharmacy operation, all need dry and break into the powder attitude.Handle sticky shape mineral powder, often adopt the drying tunnel heating, drying to stir.The pharmacy operation generally adopts the heating, vacuum dehumidifying to plaster material, breaks into powdery then.Above-mentioned wet stock processing method heat energy utilization rate is low, and processing speed is slow, and promptly efficient is low, cost is high.

The purpose of the utility model be provide a kind of to wet stock oven dry, stir carry out simultaneously, thermal efficiency height, processing speed be fast, and the agitator of the uniform wet stock dryer of discharging.

Described agitator has vertical mixing drum, and the center is adorned by motor-driven rotating shaft, is the cone-shaped of intermediate projections and the cone base diameter diameter less than mixing drum at the bottom of the mixing drum, and the lower end of stirring barrel did not link to each other with the cone-shaped tube end, formed the air inlet of ring-type.The annular heat air compartment surrounds mixing drum, and base, hot blast chamber tilts and links to each other with the base at the cone-shaped tube end.Hot-flow flue tangentially is communicated with the hot blast chamber.A center at the bottom of rotating shaft is contained in tin, its top dress impeller blade is near cone-shaped tube bottom dress stirring vane.The ring that stirs relative stirring vane position on the barrel has a plurality of fresh air inlets on week.Open charging aperture on the sidewall on mixing drum top, the pipeline of connecting conventional cyclone separator is arranged at the mixing drum top.

Described agitator pushes plaster material continuously in charging aperture, it is by gravity fall, and the impeller blade cuts that is rotated is clashed into the follow-up whereabouts of continuing.Because be cone-shaped at the bottom of rotary centrifugal force effect and the mixing drum, material will drop on a feather edge, i.e. ring-type air inlet place.The high temperature and high speed hot blast tangentially enters the hot blast chamber, and pours mixing drum by ring-type air inlet place, material is rotated up blow afloat, and toasts wet stock simultaneously.Do not dried the material that still is the larger particles shape, fallen again along barrel, be cut, clash into, stir, toast, dried the material that is the powder attitude and taken out of cyclone separator and the flow separation that described agitator enters routine by air-flow according to gravity and rotary centrifugal force.There is relatively large wet stock group to drop on ring-type air inlet place for preventing that charging rate is too fast, air-flow is difficult to for the moment material group blown afloat and causes the obstruction in short-term of ring-type air inlet, cause the agitator discharging inhomogeneous, at a plurality of fresh air inlets place air intake that stirs barrel ring Zhou Shangkai, making the material top of blocking the ring-type air inlet is low-pressure area, under airflow injection and blade stirring action, can guarantee that the ring-type air inlet does not get clogged, discharging is even.Adopt described agitator to handle wet stock, material is cut, can carry out heat exchange fully with high temperature gas flow in the bump, whipping process.The efficient height, processing speed is fast, discharging is even.

Fig. 2 is the A-A view of Fig. 1.

Vertical mixing drum 2 centers dress rotating shaft 4, this axle is by motor-driven.At the bottom of the mixing drum 8 be cone-shaped and the cone base diameter less than mixing drum 2 diameters.The bottom of mixing drum 2 walls with 8 do not link to each other at the bottom of the tube, form ring-type air inlet 7, this air inlet is within the projected area of mixing drum 2, annular heat air compartment 3 surrounds mixing drums 2, the base 10 of hot blast chamber 3 slopes inwardly and links to each other with 8 base at the bottom of the tube.Hot-flow flue 13 tangentially is communicated with hot blast chamber 3.At the bottom of rotating shaft 4 is contained in tin 8, its top dress impeller blade 5 near tube place, the ends 8 a dress stirring vane 6, has connecting rod 11 to connect impeller blade 5 and blades 6, to gain in strength.The ring at relative blade 6 positions has the fresh air inlet 9 of a plurality of strips on week on mixing drum 2 walls.Open charging aperture 12 on the sidewall on mixing drum 2 tops, the pipeline 1 of connecting conventional cyclone separator is arranged at mixing drum 2 tops.

Claims

1, the mixer of plaster material drying machine, vertical mixing drum 2 is arranged, be equipped with by motor-driven rotating shaft 4 at the center, it is characterized in that at the bottom of the mixing drum 8 cone-shaped for intermediate projections, and the cone base diameter is less than the diameter of mixing drum 2, the lower end of mixing drum 2 walls did not link to each other with the cone-shaped tube end 8, form the air inlet 7 of ring-type, annular heat air compartment 3 surrounds mixing drum 2, base, hot blast chamber 10 tilts and links to each other with 8 base at the bottom of the tube, hot-flow flue 13 tangentially is communicated with hot blast chamber 3, and rotating shaft 4 tops dress impeller blade 5 is near tube place, the ends 8 dress stirring vane 6, the ring at relative stirring vane 6 positions is on week on mixing drum 2 walls, have a plurality of fresh air inlets 9, open charging aperture 12 on the sidewall on mixing drum 2 tops, the pipeline 1 that is communicated with conventional cyclone separator is arranged at the mixing drum top.
