Description

A kind of drying machine

Technical field：

Heating being dried to mixing the mixture formed by building stones and reclaimed materials the utility model is related to a kind of Device.

Background technology：

The bituminous paving reclaimed materials and building stones to get off at present to milling is that heating is dry respectively in two independent drying cylinders Dry, right latter two material, which enters back into mix in cylinder, to be mixed.

The existing drying machine that heat drying is carried out to reclaimed materials is that open fire is heated to hot-blast stove, and temperature control difficulty is big, cuts The hard pitch flue gas of generation and the flue gas of bituminous mixing plant enter dust pelletizing system together, and the flue gas of high temperature can make dust pelletizing system At damage, the case where also occurring that equipment burnout sometimes due to bitumen flue gas temperature is excessively high, security risk is very big.

The existing drying machine that building stones are carried out with heat drying includes inclined cylinder gradually downward from the front to the back, before cylinder End is connected with discharging smoke box, and the rear end of cylinder is connected with charging smoke box, and charging smoke box is equipped with material inlet, the bottom for the smoke box that discharges Portion is equipped with material outlet, is fixed with spiral helicine sliding plate on cylinder back-end inner wall, the cylinder inboard wall in front of sliding plate is equipped with Lifting blade, the cylinder inboard wall in front of lifting blade are equipped with material rotating plate, and the cylinder inboard wall in front of material rotating plate is equipped with scraping wings, burning The flame of device is entered from discharging smoke box in cylinder, is thermally dried to material.If building stones and reclaimed materials formed mixed Conjunction material, which is sent into it, to be thermally dried, and due to containing pitch in reclaimed materials, pitch can be burnt always with direct flame contact Change, pitch is made to fail.

In addition two drying cylinders are set more there is also investing, take up an area big, the high problem of production cost.

Invention content：

The technical problem to be solved by the utility model is to provide it is a kind of can be to being made of building stones and reclaimed bituminous pavement Mixed material is thermally dried, and pitch will not be burnt, and drying effect is good, small investment, the drying machine taken up little area.

What above-mentioned purpose was realized in：It includes holder, and motor is rack-mount, there is support roller on motor output shaft, Further include that inclined cylinder, cylinder outside are equipped with rolling ring gradually downward from the front to the back, the rolling ring of cylinder is placed on support roller, motor work Work can drive barrel body rotation, the front end of cylinder to have discharging smoke box, the rear end of cylinder to have charging smoke box, charging smoke box to be equipped with material The bottom of import, the smoke box that discharges is equipped with material outlet；It is characterized in that：

Several material scraping plates are fixed on barrel front end outer wall, the outer end of material scraping plate is contacted with the wall of discharging smoke box；

Be fixed with several preceding stock guides in cylinder front inner wall, the preceding stock guide on cylinder inboard wall in the shape of a spiral Arrangement, fiery cylinder are mounted on the front in cylinder by fiery tube stent, and burner is extend into from discharging smoke box in cylinder, burner Crater is opposite with fiery cylinder；

Choking coil is equipped in the cylinder at preceding stock guide rear, choking coil is mounted on choked flow coil support, and choked flow coil support is solid It is scheduled on cylinder inboard wall；Several preceding sliding plates being obliquely installed are fixed on cylinder inboard wall outside choking coil；Choking coil with There are distances for the bottom of sliding plate；When work, heat smoke passes through in the middle part of choking coil, and material is between choking coil and sliding plate Space passes through；

Several rear stock guides are fixed on the cylinder inboard wall at preceding sliding plate rear, the rear stock guide is arranged in the shape of a spiral Row；The rear stock guide bottom is bent to side, keeps rear stock guide approximate and L-shaped；

Spiral helicine rear sliding plate is fixed on the cylinder inboard wall at stock guide rear afterwards.

The utility model has the advantages that：Cylinder rotates when work, and mixed material is driven to move from back to front, and heat smoke is in the past It moves backward, stock guide raises mixed material and is scattered in cylinder after, and carrying out adequately heat with the heat smoke in cylinder hands over It changes, makes mixed material drying heating, then the premenstrual stock guide overturning of mixed material, makes material homogeneous heating, then go out from material Mouth outflow.Due to being equipped with fiery cylinder in cylinder, flame can be isolated with mixed material for fiery cylinder, flame not with material directly contact, It can prevent the pitch in reclaimed materials from being burnt aging, the flue gas that in addition pitch generates can be burned off, and reduce the discharge of noxious fume. The fine powder material of building stones can wrap up reclaimed materials and bitumen flue gas in switching process, be handled.

Due to being equipped with choking coil, the bitumen flue gas that is generated in can heating reclaimed materials is forced to being burnt up by flame in the middle part of cylinder, To reduce the discharge of harmful smoke.

The present apparatus can dry the mixed material added with reclaimed materials, can also dry the material without containing reclaimed materials, realize One dual-purpose, to reduce investment, reduces production cost, takes up an area few.
