Description

Combined dry bolting mill with rotating-vibrating disk

The utility model is a kind of chemical industry equipment dry and that screening is used in combination that shakes that revolves, and is applicable to that various surfaces in the industry such as chemical industry, pharmacy, food contain the dry and screening of the powder and granule shape material of moisture content.

Powder body material drying device has various ways, if any adding hot-air directly and the pneumatic drier of powder body contact drying, cyclone drying machine, boiling drier etc.This drying device thermal loss that hot-air is directly contacted with the powder body is big, and the thermal efficiency is low, there are cross pollution in hot-air and material, needs many attaching devices such as air-supply, insulation, exhaust, air-treatment.The inside powder body strong agitation formula drying machine that the sleeve pipe heating is also arranged, this dried forms powder body are broken easily, between inwall and the stirring pen feather quiet space uneven drying are arranged, and powder body physical property significantly changes, and influences product quality.In addition, also exist the axle envelope to sneak into shortcomings such as foreign matter from hermetic unit.

Therefore, a lot of novel vibrating drying machines appear in recent years, as the vibrating dryer (patent No. SU798457, SU712629, SU1062484) of the Soviet Union, the vibration continuous multi-stage drying machine (the clear 55-50266 of the patent No.) of Japan.

Vibrating dryer has many good qualities: because vibration is flowed airborne powder or granule materials, have the characteristics of agitated dryer, can reduce intergranular friction again, crystalline form is complete, and material is heated evenly, and the heat energy consumption is little.

But vibrating dryer still has and waits improved place, and it is bigger influenced by loading capacity as particle in flow regime, and the in a single day too high flow model of loading height worsens, influence drying effect and drying capacity, the thermal efficiency is low in addition, and utilization rate of equipment and installations is low, and production capacity is low.

The purpose of this utility model is to keep on the basis of vibrating dryer advantage, design the dry screen-dividing machine of a kind of combined type rotating-vibrating disk, make it under the equal volume status of equipment, drying area doubles, thermal efficiency height, production capacity are big, this machine dry sieve divides combination to use energy savings.

The purpose of this utility model is achieved in that this machine is made of following six parts, top cover, cylinder, is loaded with disk, sieve nest, exciting device, the support of plane snail volume guide plate.

But level is equipped with the disk of multilayer heating medium heating in the cylinder of the utility model drying screening machine, vertical with disk alternate be equipped with suitable, inhour plane snail volume guide plate, every layer of alternate outer feed opening and center feed opening of being equipped with of disk outer circumferential side with the center, material is when the charging aperture of top cover is added on the ground floor disk, since the exciting material except that do self stir, and roll up guide plate along clockwise direction plane snail and move, move to outer circumferential side from the center, fall into the place, outer of second layer disk by the outer feed opening, and roll up guide plate along counter-clockwise direction plane snail and do same self stirring and moving, move to second layer disc centre place, fall on the second layer disk by the center feed opening, so recycle stock moves to outer circumferential side by the 3rd layer of disc centre place, fall into the 4th layer of disk outer circumferential side from the outer feed opening, fall into sieve nest from the 4th layer of disc centre feed opening at last.Material had both been reached the purpose of drying through in the process of every layer of disk with disk chuck thermal medium indirect by cylinder.The dry disk number of plies can increase or reduce according to the product yield size.The material that is dried falls into sieve nest, and after being sieved by exciting, lump material is emitted by the lump material outlet, and finished product cools off the back in sieve nest is emitted by the finished product discharging opening, and moisture is emitted by exhaust outlet through center and outer feed opening.

The advantage of this machine is that dry sieve divides combination to use, compact conformation, utilization rate of equipment and installations height, and the equipment drying area of equal volume doubles, and material is subjected to that three kinds of modes are conducted heat, thermal efficiency height.Revolve vibration again because exciting device produces, material was both moved along plane snail volume guide plate, can stir again, augmentation of heat transfer improves drying efficiency.Every layer in this machine is loaded with the cylinder, sieve nest of the disk of plane snail volume guide plate can monoblock type or dissection type assembling, can increase or reduce the disk number of plies according to the product quality size.When product need not to sieve, can remove sieve nest or screen cloth and form single formula rotating-vibrating disk drying machine.This machine assembling is flexible, easy to process, cost is low, can reduce pressure or atmospheric operation, also can intermittence or continued operation.

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