Device 3 is handled.
A kind of original recycled aggregate drying equipment integral method, including three kinds of operating conditions, i.e., dry simultaneously primary aggregate with again
Raw aggregate only dries primary aggregate use, the only use of drying recycled aggregate.
Primary aggregate and recycled aggregate are dried simultaneously, steps are as follows for working principle:
Step 1, primary material drying roller 1 are with ignition temperature by the driving rotation of the first variable-frequency motor 11, burner 12
1300-1500 DEG C of temperature carries out heating work, and primary aggregate is entered by primary material feed inlet 14, and burner 12 is to primary aggregate
It is dried with countercurrent heat exchange method, the primary aggregate after drying is sent out by primary material discharge port 15；
Step 2,450-600 DEG C of the high hot exhaust gas that primary material drying roller 1 generates pass through hot cigarette in the first air inducing case 13
Pipe 4 enters in reworked material drying roller 2 from hot fume entrance 22, and reworked material drying roller 2 is rotated by the second variable-frequency motor 21,
Reworked material is entered by reworked material feed inlet 24, and reworked material and hot fume are dried with countercurrent heat exchange method, the reworked material after drying by
Reworked material discharge port 25 is sent out；
At the same time, the tail gas of primary aggregate drying roller 1 some the first air inducing case 13 pass through the first dedusting
Pipe 6 is connected to the processing of deduster 3, and hot smoke pipe 4 is equipped with the first air-introduced machine 41, and the first dust removing tube 6 is equipped with third air-introduced machine 61,
By adjusting the power of the first air-introduced machine 41 and third air-introduced machine 61 to adjust the stream that hot fume enters reworked material drying roller 2
Amount, while 11 revolving speed of the first variable-frequency motor of coordinated control, adjustment are with control 2 hot fume inlet temperature of reworked material drying roller
450-600 DEG C and control the first dust removing tube 6 be sent into deduster 3 temperature control at 90-110 DEG C.
Step 3, the tail gas that reworked material drying roller 2 generates return to primary material by offgas duct 5 in the second air inducing case 23
Drying roller 1 is sent into equipped with 12 one end of burner, and remaining heat is sent back in primary material drying roller 1 in tail gas, while tail
Gas is reduced the content of harmful substance in tail gas at burner 12 by second-time burning.
At the same time, deduster 3 provides negative pressure by the 4th air-introduced machine 31, and offgas duct 5 is equipped with the second air-introduced machine 51, leads to
Adjustment 51 power of the second air-introduced machine is crossed to adjust the tail gas for being recovered into primary material drying roller 1, while the first frequency conversion of coordinated control
Motor 11,21 revolving speed of the second variable-frequency motor further control primary 1 first air inducing case of material drying roller, 13 outlet temperature, and control
Making the second dust removing tube 7 and being sent into the exhaust temperature control of deduster 3 is 90-110 DEG C.
To sum up, primary material drying roller 1, reworked material drying roller 2 only used one group of burner 12 as heating dress
It sets, reworked material drying roller 2 is in such a way that hot fume heats, and relative to conventional burners heating method, heating temperature is more
Uniformly, it is ensured that reworked material is in heating, drying under preference temperature, and avoids burner flame contact reworked material and occurred
Heat problem can save the design of burner hearth, can reduce material and glue cylinder problem, equipment cost, clean and maintenance cost all significantly drop
It is low；According to primary aggregate and recycled aggregate self-characteristic, primary aggregate heating temperature is higher, recycled aggregate heating temperature is lower,
Therefore, the high-temperature tail gas after the completion of primary aggregate heating, drying is enough to provide recycled aggregate heating, drying required temperature, reworked material
2 tail gas of drying roller sends primary 1 second-time burning of material drying roller back to by offgas duct 5 again, and after-heat is recycled again, into
One step reduces fuel cost, and tail gas second-time burning, and full combustion can reduce pernicious gas content in tail gas；On each pipeline
Air-introduced machine revolving speed it is adjustable, the first variable-frequency motor 11 and the second variable-frequency electric of primary material drying roller 1 and reworked material drying roller 2
The also adjustable revolving speed of machine 21, passes through each coordinated control, it is ensured that primary material drying roller 1 can be fitted with reworked material drying roller 2
The demand for answering operating temperature under different operating conditions guarantees the quality requirements of product, while it is useless also to can control the processing of deduster 3
The temperature of gas promotes the working efficiency and working life of deduster 3, and circulation of tail gas, which uses, also can reduce 3 operating pressure of deduster.
It only dries primary aggregate to use, steps are as follows for working principle:
The primary rotation of material drying roller 1, burner 12 work, and close hot smoke pipe 4, primary aggregate is by primary material feed inlet 14
Into burner 12 dries primary aggregate with countercurrent heat exchange method, and the primary aggregate after drying is sent by primary material discharge port 15
Out, the first air inducing case 13 is expelled to atmosphere after sending tail gas to the purification of deduster 3 by the first dust removing tube 6.
Recycled aggregate can be only dried, steps are as follows for working principle:
The burner 12 of primary material drying roller 1 works, and closes the first dust removing tube 6, the hot gas of generation is in the first air inducing case
13 by hot smoke pipe from hot fume entrance 22 enter reworked material drying roller 2 in, reworked material drying roller 2 rotate, reworked material by
Reworked material feed inlet 24 enters, and reworked material and hot fume are dried with countercurrent heat exchange method, and the reworked material after drying is gone out by reworked material
Material mouth 25 is sent out, and a part of tail gas is returned to primary material drying roller 1 equipped with burner by offgas duct 5 by the second air inducing case 23
12 one end are sent into, and remaining heat is sent back in primary material drying roller 1 in tail gas, while tail gas is secondary at burner 12
It burns to reduce the content of harmful substance in tail gas, a part is sent by the second dust removing tube 7 to processing discharge in deduster 3.
Realize the integrated integrated system that a set of equipment is suitable for various working.
It above are only a kind of specific embodiment of the invention, but the design concept of the present invention is not limited to this, all benefits
It is made a non-material change to the present invention, should all be belonged to behavior that violates the scope of protection of the present invention with this design.
