Description

Rotary drum continuous granulator

Technical field

The present invention relates to a kind of rotary drum nodulizer.

Background technology

Nodulizer is widely used in industries such as pharmacy, metallurgy, chemical industry, building materials, the round shaped grain degree of its product is a leading indicator of weighing the nodulizer performance, the round shaped grain degree is good more, porosity by its product that constitutes is high more, as being used for the ceramsite propping agent of oil exploitation, its porosity is high more, will improve in-place permeability, make the oil gas circulation, improve oil and gas production; Present widely used rotary drum nodulizer, as depicted in figs. 1 and 2, comprise cylinder 34, the rolling mechanism of frame 31, band portable cover 32 and discharging hatchcover 33, described cylinder 34 is that a cylinder and preceding high back are low, establish several piece plane flight 35 in it, an end of flight 35 and the inwall of cylinder 34 connect firmly; Described rolling mechanism comprises main motor 36, decelerator 37, pinion 38, be fixed in the outer bull gear 39 of cylinder 34 and be located at several support rollers 40 on the frame 31, be fixed in outer at least two rolling rings 41 of cylinder 34, rolling ring 41 cooperates with support roller 40, back-up roller 34; During use, earlier pre-wet feed is put into cylinder 34 from hatchcover 32, by rolling mechanism cylinder 34 is rotated, flight 35 is constantly taken up pre-wet feed, is fallen from the bottom of cylinder 34, so after operation a period of time, shut down again and open hatchcover 32, add certain siccative and water, be rotated further cylinder 34, after after a while, can obtain spheric granules; But this rotary drum nodulizer is controlled than difficult in axial translational speed material, cause most of material just to move to the rear end of cylinder 34 within a short period of time, making material all concentrate on this zone in the most of the time is constantly taken up, falls by flight 35, material is maldistribution in cylinder 34, cause it shorter along the curve that inner wall of rotary drum rolls in the unit interval, it is insufficient to roll, and the round shaped grain degree is relatively poor; Root area at every flight 35 forms the dead angle simultaneously, and partial material accumulates in this place, is difficult to roll, and has reduced yield rate, also need increase screening process; And use this equipment, need the compartment of terrain to shut down,, reduced production efficiency so that reinforced and taking-up product can not be realized serialization production.

Summary of the invention

The objective of the invention is the above-mentioned deficiency at prior art, a kind of rotary drum continuous granulator is provided, the product that it was produced has the advantage that the round shaped grain degree is good, yield rate is high, and can realize serialization production, has improved production efficiency.

For achieving the above object, rotary drum continuous granulator of the present invention, comprise frame, cylinder, rolling mechanism, high back is low before the described cylinder, it is characterized in that being provided with in the described cylinder two or more sub-cylinders, the inwall of each sub-cylinder is provided with the axial flight of several piece, terminal center in last sub-cylinder of adjacent two sub-cylinders is equipped with little tube, the front end sealing of this little tube, correspondence is provided with two or more imports on its sidewall, between last sub-cylinder and little tube, also be provided with two or more and the corresponding stock guide of import separately, the rear end of little tube communicates with a back sub-cylinder, sub-cylinder foremost is provided with centre bore, and a feed hopper and siccative feed mechanism are loaded on the preceding frame of sub-foremost cylinder, and a discharge bucket is located on the sub-cylinder of rearmost end.

Above-mentioned siccative feed mechanism comprises motor, decelerator, sprocket wheel chain gearing, is installed on the auger conveyor on the frame, the rotating shaft of described auger conveyor is a quill shaft, one feed pipe is loaded in the rotating shaft, the part that is positioned at the auger conveyor end outside at feed pipe is provided with several shower nozzles, and the discharge gate of auger conveyor and several shower nozzles all are positioned at sub-cylinder foremost.

During use, by rolling mechanism cylinder is rotated, in sub-cylinder foremost, add pre-wet feed by feed hopper, material is taken up by flight, along stock guide, enter in the little tube, roll into next sub-cylinder again, during this period continuously by the import on the sidewall, can import about 1/5th siccative and water smoke by the siccative feed mechanism, so that best balling-up condition to be provided; So circulation is discharged by discharge bucket until material; In the course of the work, because the import that material need advance on the too small tube enters next sub-cylinder, material can be controlled in axial translational speed, material is distributed uniform in cylinder, cause it longer along the curve that inner wall of rotary drum rolls in the unit interval, roll fully, the round shaped grain degree is good; And use this equipment, need not to shut down and just can feed in raw material, add water and discharge, can realize serialization production, improved production efficiency.

As a further improvement on the present invention, described flight is the arch flight, and the both sides of arch flight and the inwall of sub-cylinder connect firmly; This flight can be eliminated the dead angle area of root, avoids the gathering of partial material, forms slow-witted material, has improved yield rate.

As a further improvement on the present invention, described each sub-cylinder is circular arc at four axial corners; Can avoid forming dead angle area, further improve round shaped grain degree and yield rate at sub-cylinder.

As a further improvement on the present invention, described discharge bucket is located at the terminal center of the sub-cylinder of rearmost end, discharge bucket is positioned at the front end sealing of sub-cylinder, its sidewall is provided with two or more imports, also is provided with two or more and the corresponding stock guide of import separately between sub-cylinder and discharge bucket; Can improve the curve that material rolls along inner wall of rotary drum to greatest extent, and be convenient to discharge.

As a further improvement on the present invention, be provided with two or more and the corresponding baffle plate of import separately in described each little tube and the discharge bucket; Baffle plate can avoid partial material to be back in the sub-cylinder, enhances productivity.

In sum, the product that the present invention produced has the advantage that the round shaped grain degree is good, yield rate is high, and can realize serialization production, has improved production efficiency.
