Abstract

The utility model relates to a grinding head drum type dryer for drying cement materials directly entering a ball mill, composed of an air locking hopper, a drying drum and an aligning hopper. The materials and hot fume enter the drying drum through the air locking hopper to carry out drying, and then pass through the aligning hopper to enter the ball mill. Capable of controlling temperature of system reasonably and broadening the comprehensive content of water of the materials required in the original technology, the utility model has the advantages of high heat utilization rate, simple structure, simple transformation of old technology, high safety as well as convenient operation and maintenance.

Description

Bistrique cartridge type dryer

The utility model relates to a kind of dryer.

Cement production process has strict requirement to the water content of ball mill mill feed material.All there is independently drying materials system in most producers, and the material that water content is high is stand-by by being transported to the storage storehouse after the oven dry one by one.The producer that also has adopts an oven dry of ball mill hollow axle end suspension storehouse is dried material in the storehouse after and enters grinding machine, perhaps in ball mill, set up an oven dry storehouse or directly high-temperature flue gas is fed ball mill, make material fragmentation while drying, though this method is simplified drying system to a certain extent, improve main frame output, but also there is following some deficiency: 1, can not give full play to the effect that bistrique is dried this process procedure, drying course is short, the water content that enters the material of drying the storehouse is still had very strict requirement, suppressed the raising of grinding system ability; 2, dry the storehouse or in grinding machine, set up the load that the oven dry storehouse all will increase the grinding machine bearing in the suspension of grinding machine hollow axle end,, can't adopt for the producer that has raw mill now with respect to the bearing capacity and the lubricating requirement raising of bearing; 3, the design selected technology that installation and securing member are set in oven dry storehouse is also very unripe.

The purpose of this utility model is to provide a kind of bistrique dryer, makes it give full play to the effect that bistrique is dried this process procedure, relaxes the requirement to material moisture on technology, improves the production capacity of grinding system.

The technical solution of the utility model is: it is made up of lock wind hopper, oven dry tube, aligning hopper three parts, the oven dry tube is between lock wind hopper and aligning hopper, one end of lock wind hopper is connected with the flue flange, the other end inserts in the centre bore of oven dry tube feed end, and the top of lock wind hopper is provided with and is subjected to material small bucket; The discharge end of oven dry tube inserts the charging hole of aligning hopper, and the discharge nozzle of aligning hopper inserts the quill shaft of ball mill, and the top of aligning hopper is provided with the meal inlet, is connected with powder concentrator powder retrieving pipe flange; Lock wind hopper and aligning hopper are fixed on the basis, ground with supporting leg; The oven dry tube adopts the supporting of backing ring support roller, and backing ring is fixed on the cylindrical shell, and support roller is fixed on the basis, ground by the support roller seat; Described oven dry tube passes through reduction box, pinion, gear wheel driven rotary by motor.

Be delivered to lock wind hopper through deployed cement material by belt, enter the oven dry tube from being subjected to material small bucket, hot blast enters the oven dry tube through the warm-air pipe of lock wind hopper, and material rolls in the oven dry tube and advances, and oven dry enters ball mill through the aligning hopper then while advancing.After being dried, material directly enters ball mill in the cartridge type dryer, can improve the production capacity of grinding system significantly, heat energy utilization rate height not only, energy consumption is low, and the reasonable control system temperature of energy, the comprehensive moisture of the material of former technological requirement can be relaxed more than 3 times.This equipment investment is little, is convenient to old technological transformation, can be according to producer's actual working environment dryer rotating speed reasonable in design, draw ratio and cylindrical shell gradient, and simultaneously, dryer is relative with ball mill centre-to-centre spacing to be dwindled, and it is few to take height space, and maintenance operation is convenient.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, the utility model is made up of lock wind hopper 1, oven dry tube 2, aligning hopper 3 three parts, one end of lock wind hopper is connected with the hot blast fume pipe by flange, the other end inserts in the central through hole of oven dry tube feed end, the top of lock wind hopper is subjected to material small bucket 9 by the flange connection, cement material is fixed on the basis, ground with supporting leg 8 at the middle part of lock wind hopper via being subjected to material small bucket to enter the oven dry tube.The oven dry tube supports and is fixed on the basis, ground by support roller seat 7 by backing ring 6, support roller 5.The aligning hopper is arranged on the discharge end of oven dry tube, is fixed on the basis, ground by supporting leg 4.The discharge nozzle of aligning hopper inserts the quill shaft of ball mill, and the top of aligning hopper is provided with the meal inlet.

As shown in Figure 3, Figure 4, lock wind hopper of the present utility model is by formed by material small bucket 9, warm-air pipe 10, square top and round bottom warm-air pipe 11, each several part connects with flange, hot blast enters warm-air pipe by the square top and round bottom warm-air pipe, enters the oven dry tube then, enters dryer for preventing natural wind, be provided with counterweight lock aerofoil 12 at the blanking skew notch that is subjected to material small bucket, the bottom of warm-air pipe 10 is provided with the little bucket 13 of scarfing cinder of a band door, can remove sediment in the pipe, and it is smooth and easy to keep ventilating.

As shown in Figure 2, the discharge end of oven dry tube of the present utility model is provided with the guide passage that is formed by arc stock guide 14, striker plate 15, conical tube 16, carries out guide with this passage, enters the aligning hopper again more than material can being risen to discharge end center height.Like this, under the little situation of dryer and ball mill centre-to-centre spacing, guarantee the drop at material and ball seat machine center, make the discharging successfully of aligning hopper.Be provided with access door on oven dry tube cylindrical shell, cylindrical shell every wet, adopts the lifting blade 17 of three kinds of different angles with insulation material in the cylindrical shell, and lifting blade is fixed by bolts on the lifting panel seat of cylinder inboard wall.
