Description

Drum-type bacterial manure dryer

The utility model relates to a kind of drying plant, particularly can dry the drum-type bacterial manure dryer of operation continuously.

The drying plant that is used for bacterial manure or composite fertilizer at present, as the vertical vibrating dryer, be to be combined into vertical barrel by multilayer baking material drawer, hot-air is entered by gas channel and respectively dries by the fire the bed of material, in vibration processes, dry, this equipment can only be dried particle or lump material, can not dry by the fire powdery bacterial manure or other granular material, and drying rate is slow, efficient is low; Rotary dryer in the extensive use of cement building material industry, the dryer main body is the horizontal revolving tube, material passes through in the tube that rotates continuously, hot-air is finished drying procedure by the object of motion, using its bake out temperature of this dryer is 120 ℃～300 ℃, the temperature of oven dry bacterial manure then can not be above 70 ℃, under above-mentioned hot conditions, will kill most of organic bacterium, simultaneously in order to guarantee the oven dry of bacterial manure, the slow down translational speed of material of the time of staying of increase material in equipment that the very important person is, therefore above-mentioned two kind equipments all can not satisfy the drying requirement of bacterial manure.The disclosed patent No.: 91209731.0 titles: rotary drier patented technology, be by dry bucket, central hollow axle and driving and transmission device are formed, during work, the material that is dried is rotated drive and rolls mutually and frictional impact in dry bucket, heated drying air is in rotary course, spray by the introducing of central hollow axle and from the central shaft spray orifice of interior one section of dry bucket, the thing that is dried turns over stream on one side in bucket, handled by hot air dries on one side, this equipment removes the demand of the smoking place that can not satisfy bacterial manure, and another defective is to dry operation continuously.

The purpose of this utility model is: in order to overcome many discomforts and the defective that the said equipment exists in smoking the bacterial manure process, existing swinging drying plant is improved, design a kind of in, comprise the drying plant that all powderies, particle, the lump material of bacterial manure carry out the continuous drying operation under the cryogenic conditions.

The utility model is mainly by rotating cylinder, rotating cylinder drives and transmission device, the defeated arranging device of hot air source constitutes, motor rotates by the gear ring engagement of decelerator driven gear and rotating cylinder periphery, the support roller that is positioned at the rotating cylinder bottom places on the support roller seat in order to support rotating cylinder, one end places in the rotating cylinder as the wind conveying pipe of air inlet, the architectural feature of this equipment is: the wind conveying pipe in the rotating cylinder is the movable connection of non-rotation type, and be installed in the rotating cylinder by supporting and regulating device, one end of wind conveying pipe is an air inlet, the other end and be positioned at rotating cylinder and be provided with exhaust vent, the exhaust vent place is provided with deep bead turns to air-flow, also be provided with exhaust outlet with air inlet in same end, warm wind regime enters wind conveying pipe by air inlet, deliver to afterbody by wind conveying pipe again, thermal current enters in the rotating cylinder by the exhaust vent of wind conveying pipe afterbody and the effect of deep bead, and turns to feed end to flow, outside exhaust outlet discharge machine, connect with the dust-precipitator and the exhaust blower that collect in uniting; On the rotating cylinder of air inlet end feed pipe is installed, the other end is equipped with discharge nozzle, and the rotating cylinder inwall that is positioned at the feed pipe place is provided with helical blade.

The utility model also has following architectural feature: the wind conveying pipe outer wall is provided with the spiral striker plate, and the rotating cylinder inwall is provided with lifting blade.

Material to be dried (containing bio-bacterial manure) enters in the rotating cylinder by feed pipe, send into baking zone by the helical blade in the rotating cylinder, the lifting blade of rotating cylinder inwall constantly gives rise to the rotating cylinder middle and upper part to the material of rotating cylinder bottom in baking zone, shed downwards incessantly again simultaneously, material flows to the rotating cylinder bottom again through the wind conveying pipe in the middle part of the rotating cylinder and enters next oven dry circulation; Spiral striker plate on the wind conveying pipe has the returning charge effect, makes material slow down and guarantee that material is dried to the translational speed of discharge end, dry material outflow rotating cylinder and is discharged by discharge nozzle, finishes drying course.

The said bracket adjustment device of the utility model is made up of wind conveying pipe support, back shaft, support set and support adapter, wind conveying pipe and back shaft are fixedly connected and are integral, be provided with support set at the back shaft position, support set is connected the rotating cylinder inwall by support adapter and wind conveying pipe support, and the support set under the rotating cylinder drive is rotated along the back shaft on the wind conveying pipe.

The utlity model has following advantage:

1, this device structure can satisfy various bacterial manure and smokes technological requirement, realizes extensive continuous drying production easily, because wind conveying pipe is set in rotating cylinder, so increased the heat endurance of rotating cylinder inside;

2, be applicable to the continuous drying operation of powdery, particle, lump material under the cryogenic conditions in all;

3, reasonable in design, easy for installation, equipment drying efficiency height.

Doing one below by accompanying drawing in conjunction with embodiment of the present utility model describes in detail.
