Description
First, technical field
The invention belongs to kiln auxiliary equipment, it is used for wet pressing ferrite magnetic material dry heat system particularly with regard to one kind
System.
2nd, background technology
The production of global magnetic material magnet is concentrated mainly on Asia, Japanese based on high-grade magnet；China is with low and middle-grade magnetic
Body is main body, and the expensive goods market of partitioning portion；Other country in Southeast Asia's partitioning portion low-and-medium-grade products markets.
Because China is with good complete machine configuration market and investment environment, Japan, American-European ferrimagnet are accelerated
Manufacturing industry to China transfer.
Recent two decades, the speed that Chinese ferrite industry substantially remains in 20% or so increases, and average every five annual production is turned over
.In recent years, the output and quality and class of Chinese ferrimagnet improved a lot, and can substantially produce Japanese TDK public
The product of the various trade mark standards of department.
Permanent-magnet ferrite product accounts for 42% in high-tech sector application, such as household electrical appliances（Micro-wave oven, air-conditioning, small household appliances）, office use
Product（Duplicator, facsimile machine）, automobile, motorcycle, high-fidelity music center, gauge sensor part.Traditional low-and-medium-grade products field should
With accounting for 58%, such as loudspeaker, absorption magnet, toy motor, magnetic separation device.All in all, the performance of Chinese ferrimagnet is also
With low and middle-grade for majority, although yield height ranks first in the world, but the output value is unsatisfactory.The magnetic material gross output value of present China
26500000000 RMB, the permanent-magnet ferrite output value 6,200,000,000, soft magnetic ferrite yield 9,300,000,000, remaining samarium-cobalt magnet, Neodymium iron boron magnetic and
Metallic magnet accounts for 11,000,000,000 yuan of market.
It is the crux that wet pressing ferrite magnetic material is burnt till to dry draining.At present, the general dryer section of external kiln is longer, entirely
Portion utilizes residual heat from kiln furnace, and residual heat from kiln furnace is not enough, and temperature is at 50~80 degree, and product fills one layer, and yield is small, good product quality class
Height, energy consumption is relatively low, and ton energy consumption is 700~750 degree of electricity left and right.Domestic kiln dryer section does not utilize residual heat from kiln furnace, is used under roller rod
Elema is directly heated, and it is big to there is the section temperature difference, and product fills tall and big, but product quality is of low grade, energy consumption is higher, and ton energy consumption exists
800~1000 degree of electricity left and right.
3rd, the content of the invention
It is an object of the invention to provide a kind of rational in infrastructure, safety and environmental protection, it is energy-saving, high-efficiency high-quality be used for wet pressing iron oxygen
Body magnetic material roller kilns dry heat device.
The technical scheme is that：It is by kiln body framework, Yao Qiang, Yao Ding, kiln bottom, roller rod transmission mechanism and heating system
The parts such as system are constituted, and heating system includes kiln tail waste-heat recovery device and electric heater unit two parts, the kiln tail waste heat recovery
Device is responsible for by waste heat, waste heat branch pipe, valve and the tracheae with air outlet are constituted, composition, is arranged on the waste heat above kiln top
Supervisor is connected by blower fan with being arranged on the exhaust outlet of kiln tail, and has been uniformly arranged the gas with air outlet above every section kiln bottom
Pipe, is connected by the waste heat branch pipe for being provided with valve with waste heat supervisor.The electric heater unit is resistance wire, is arranged in kiln thorax
Between tracheae with air outlet and roller rod.
The beneficial effects of the present invention are：There is rational in infrastructure, safety and environmental protection, energy-saving, high-efficiency high-quality, both
The drying temperature of product is improved, the temperature homogeneity in dryer section kiln is in turn ensure that, product is burnt till steady quality, yield rate
Height, with good social and economic benefit.
The invention will be further described below in conjunction with the accompanying drawings.
4th, illustrate
Fig. 1 is preheating and drying of the present invention section main structure diagram；
Fig. 2 is preheating and drying of the present invention section overlooking the structure diagram；
Fig. 3 is preheating and drying of the present invention section cross section structure schematic diagram.
In figure：1 is waste heat supervisor, and 2 be waste heat branch pipe, and 3 be valve, and 4 be air outlet, and 5 be electric heater unit, and 6 be roller rod,
7 be load bearing board, and 8 be product, and 9 be kiln body framework, and 10 be waste discharge supervisor, and 11 be waste discharge blower fan, and 12 be the waste discharge mouth of pipe.
5th, embodiment
Exemplified by building one 22 section length for 44 meters of roller kilns, 1~6 section is set to preheating and drying section, 7~12 sections and set
For heating pre-burning section, 13~16 section be set to high temperature burn till section, 17~22 section be set to cooling section.As shown in Figure 1, Figure 2, Figure 3 shows,
The preheating and drying section is made up of parts such as kiln body framework 9, Yao Qiang, Yao Ding, kiln bottom, roller rod transmission mechanism and heating systems,
Heating system includes kiln tail waste-heat recovery device and the two parts of electric heater unit 5, and the kiln tail waste-heat recovery device is by waste heat
Supervisor 1, waste heat branch pipe 2, valve 3 and the tracheae composition with air outlet 4, are arranged on the waste heat supervisor 1 above kiln top by blower fan
It is connected with the exhaust outlet for being arranged on kiln tail, and two tracheaes with air outlet 4 has been uniformly arranged above every section kiln bottom, by sets
The waste heat branch pipe 2 for having put valve 3 is connected with waste heat supervisor 1；The electric heater unit 5 is resistance wire, is arranged in kiln thorax and takes out of
Between the tracheae and roller rod 6 in air port 4.When implementing the present invention, waste heat supervisor 1 cools down kiln tail by waste heat branch pipe 2 and air outlet 4
The waste heat of section is squeezed into preheating and drying section kiln thorax, passes through the regulating air volume of valve 3.Resistance wire 5 heats hot blast again, reaches it
To 200~300 degree, then hot air convection heat transfer and the radiant heat transfer of resistance wire 5 heat product 8 and load bearing board 7 jointly.At 200 degree
Following dryer section convection heat transfer' heat-transfer by convection is occupied an leading position and efficient than radiant heat transfer, so that product is uniformly dried, improves product
Qualification rate and class, the general moisture content of wet pressing ferrite magnetic material is between 13~15%.Present invention incorporates domestic and international kiln
Stove advantage, the characteristics of not being afraid of oxidation using resistance wire（Elema likes oxidation to the wind）Hot blast is heated, makes drying efficiency higher and faster,
The section temperature difference is small, and product fills tall and big, and good product quality class is high, and energy consumption is low, and ton energy consumption is in 650 degree electricity or so, and product burns till matter
Amount is stable, high yield rate, with good social and economic benefit.
