Abstract

The utility model relates to a horizontal drum drying machine, which is assembled and runs in a horizontal mode. The complete machine is driven to run by adopting pin wheels driven by chain wheels. Matched with bearing liners, the pin teeth of the pin wheels can rotate flexibly and are not easy to wear. The inner wall of the drying drum is inlaid with lifting blades with the slope angle of 10DEG in vertical and horizontal interlacing arrangement. The lifted material spreads towards one direction and is exhausted from the end of the drum flowingly. The interchange of heat of the material is carried out in the drying drum. The utility model has the advantages of complete dry, energy saving and low cost.

Description

The horizontal rotary drum drying machine

The utility model relates to a kind of " rotary dryer " that 5 ° of inclinations angle exist that have.

At present, known " rotary dryer " is mainly used in oven dry clay, coal dust, iron powder, quartz, slag, metal selects materials such as tantalite power (to see " cement equipment handbook chapter 2 71-86 page or leaf.Hunan science tech publishing house 1987 tablets held before the breast by officials).The technical characterstic of " rotary dryer " generally has 5 ° of inclinations angle, because drying cylinder body reaches its inclination discrepancy in elevation 1.2m-1.8m more than 12m-2m °, more than the inclination weight difference 2-10 ton, integral device and each parts thereof all must have the inclination angle accordingly, auxiliary with shelves wheel apparatus stable " rotary dryer " operation, resistance is big, adopt φ 3m-5m gear wheel to drive complex structure, installation difficulty is big, serious wear, admittedly barrier rate height, maintenance difficulty is big, the cost height, the oven dry material has the dead angle, and efficient is low, and power consumption is high.In addition, what need to propose is: the designer has designed a kind of " horizontal rotary drum drying machine " in earlier stage and it is characterized in that cylindrical shell is that horizontal is contained in two covers and falls on the Chinese character pin-shaped roller frame, is that the driving wheel friction of support roller drives operation.Applied for patent to State Patent Office, accepted application number: " 96 2 11282.8 ".But laying particular stress on operation, lose revolution, serious wear, production efficiency is lower.

The purpose of this utility model provides a kind of horizontal rotary drum drying machine, has both kept and improved the performance of " rotary dryer ", has effectively overcome the drawback of its existence again.Designs simplification is reasonable, and transmission operation science is energy-conservation admittedly the barrier rate is low, output is high, and small investment is good in economic efficiency.

The purpose of this utility model is achieved in that the oven dry tube of horizontal rotary drum drying machine is that horizontal is horizontal and is contained on the roller frame, and support roller is at each 3/10ths place at drying cylinder body two ends, and place's assembling chain wheel drive pinwheel moves in the middle of the drying cylinder body.56-71 pin tooth of pinwheel dress, speed ratio: 6.2-7.89, the pin tooth is joined bearing shell, adopts the 42simn metal material, improves wearability.Pin tooth and bearing shell are mounted and removable, and be replaceable, and be to rotate accordingly when stirring the pin tooth along with sprocket wheel thereupon, reduces resistance, reduces friction, and light and flexible effectively reduces the wastage, and is durable in use.Adopt 970 rev/mins on Y series L type-6 motor, ZSY type speed reducer, speed ratio: 15.6-17.5, actual 7-10 rev/min.Because drying cylinder body (main element) is level, thereby all parts and auxiliary equipment all be the level assembling, and complete machine then is a level run, pressure balance, and simple installation is easily gone, and it is little to wear and tear, admittedly the barrier rate is low, maintenance is easy.Drying cylinder body inwall insert has the lifting blade at 10 ° of inclinations angle, length 600-800mm, and vertical component width 160-200mm, lower width 100-120mm, arc angle is 25 °.Circumference is vertically arranged routine 12-16 sheet, and laterally staggered row's example is avoided the dead angle between lifting blade and the lifting blade, 20-33 row.When dryer rotated, lifting blade rose to 90 ° of angles when above with material, and beginning is alternately raised continuously to inclination side and spread, and has highly spread to 150 °.Material is space and thermal current (700 °-800 °) in drying cylinder body, directly carries out exchange heat, the moisture content that contains in the baking stimulating food material.The lifting blade that tilts is alternately raised to the oven dry end direction and is spread, and flows to discharge gate.Dried by the fire the material moisture content of discharging and be no more than 1%, unit-hour output 8-40 ton (specification different output difference) is according to material water content control inlet amount.

The utility model is owing to take such scheme, and is simple in structure, and it is convenient to install with maintenance, admittedly the barrier rate is low, the efficient height, save steel, energy-conservation, cost is low.

The utility model concrete structure further specifies with preferred plan in conjunction with the accompanying drawings.
