Beneficial effect
The utility model neodymium iron boron waste material comprehensively reclaims roasting cellar for storing things stove residual heat using device, designs the using residual heat from kiln furnace use device with better layout, and it can be brought up to utilization rate of waste heat more than 70%, for manufacturer obtains remarkable economic efficiency and social benefit.
Description of drawings
Fig. 1 comprehensively reclaims roasting cellar for storing things stove residual heat using device sketch map for neodymium iron boron waste material.
Among Fig. 1: disperse to take out that hot air duct 1, hot blast gather that the total lock of pipeline 2, air intake 3, waste heat air-introduced machine 4, dual-purpose cold and hot wind adjusting device 5, hot blast are responsible for 6, hot blast collecting hood 7, air intake arm 8, regulating gate 9, hot blast evacuated tube 10, air-introduced machine 11, insert door 12, air intake secondary air channel 13, the total lock 14 of air-out.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
The dispersion that the roasting cellar for storing things stove residual heat using device that comprehensively reclaims neodymium iron boron waste material contains the kiln salband is taken out hot air duct 1, hot blast and is gathered the total lock of pipeline 2, the total lock 3 of air intake and air-out 14, waste heat air-introduced machine 4 and hot blast collecting hood 7, a pair of air-introduced machine 11, a pair of slotting door 12 and the pair of air inlet secondary air channel 13 that also have and disperse to take out hot air duct 1 to join; Said waste heat air-introduced machine 4 is high-power air-introduced machines, can the turnover rate of hot blast be increased to 8-12 times/minutes and said hot blast gathers pipeline 2; It also disposes a dual-purpose cold and hot wind adjusting device 5; Said hot blast collecting hood 7 tops and hot blast gather and are provided with air intake arm 8 between the pipeline 2; It also contains and comprises that the total lock of air intake 3, hot blast are responsible for 6, the hot blast control mixing system of the total lock 14 of air-out and regulating gate 9, and the hot blast emptying system that joins with hot blast evacuated tube 10.
Hot air apparatus in the said dual-purpose cold and hot wind adjusting device 5 is 10-60 ten thousand kilocalories a small-sized concurrent heating fuel gas hot-blast stove.
With reference to Fig. 1; The roasting cellar for storing things stove residual heat using device that comprehensively reclaims neodymium iron boron waste material contains that hot air duct 1 is taken out in the dispersion that is configured in the kiln salband and the hot blast that is attached thereto gathers pipeline 2, the total lock 3 of air intake and the total lock 14 of air-out; Also have surplus heat air-introduced machine 4 and hot blast collecting hood 7, a pair of air-introduced machine 11, a pair of slotting door 12 and pair of air inlet secondary air channel 13 are taken out hot air duct 1 with dispersion and are joined; It also is furnished with a dual-purpose cold and hot wind adjusting device 5; Promptly when 10 ℃ of environment temperatures and following or kiln truce repairing, bring into play the concurrent heating effect, and when environment temperature is higher than 30 ℃; But suction cold air again; With suitable reduction hot blast temperature, the temperature that makes hot blast get into drying room is controlled in 70-90 ℃, is dried excessively to prevent base substrate; Gather at said hot blast collecting hood 7 tops and hot blast and to be provided with air intake arm 8 between the pipeline 2, be used to increase waste heat extraction amount, reduce the temperature that hot blast gathers hot blast in the pipeline 2,, reduce the heat loss of waste heat in carrying again to prolong the service life of waste heat air-introduced machine 4; The external emptying of residue hot blast during the hot blast emptying system that joins with the hot blast evacuated tube can will install when environment temperature surpasses 30 ℃; Traditional big 1-3 times of the power ratio of said waste heat air-introduced machine is original 1. 5-2. 0 times and hot blast gathers the diameter of pipeline 2, and it can make hot blast rate significantly increase.
