Abstract
The utility model relates to a low temperature drying screening machine for biological fertilizer. Hot air pipes of an air heater is connected with the hot air pipes longitudinally extending into a drying barrel; the utility model at least is provided with two hot air pipes; one hot air pipe approaching to a feed inlet port is longest; the hot air pipe extending into the middle part of the drying barrel is longer; the hot air pipe approaching to a discharge port is shortest; an inner end is connected with a circular hot air blowing port; air eyes are evenly distributed on the circular hot air blowing port. The utility model can effectively solve the technical problem that because of high drying temperature and long drying time, the survival rate of the microbial bacterium preparation can be reduced in the process of drying biological fertilizer. The utility model is suitable for drying and screening the biological fertilizer and the compound fertilizer.
Description
The utility model belongs to a kind of oven dry screening plant, especially for the oven dry sieve apparatus of bio-feritlizer.
Existing dryer comprises oven dry rotating cylinder, induced draft fan, opening for feed, actuating unit, discharge port, material screen, calorifier, calorifier have two kinds by holding position: a kind of calorifier is installed in opening for feed one end, be fed the calorifier drying of end when material after, high humidity because of the opening for feed material, the humidity of discharge port is little, along with the oven dry rotating cylinder rotate into discharge end the time, become tide again easily and make material bonding and produce the particle uneven phenomenon; Another kind is that calorifier is installed in discharge port one end, when the material of humidity enters the oven dry rotating cylinder from opening for feed after, the discharge port that rotates into along with the oven dry rotating cylinder, the hot blast of calorifier input is the highest in discharge port place temperature, and minimum in opening for feed place temperature, though improved the drying property and the easy agglomerating problem of adhesion of material, because discharge port temperature height, the problem that also causes the microbiobacterial agent surviving rate to reduce easily is directed at drying rate decline again if reduce the temperature of hot blast.
The purpose of this utility model provides a kind of improved bio-feritlizer oven drying at low temperature sieve apparatus, the oven dry material had not only been kept dry when discharging but also guarantees the surviving rate of microbiobacterial agent, improves product quality and production efficiency.
The technical solution of the utility model is:
Bio-feritlizer oven dry sieve apparatus, comprise drying cylinder body, opening for feed, induced draft fan, calorifier, volume damper, the revolution screening plant, discharge port, power-driven gear, gear wheel, support roller, roller, calorifier is at an end of discharge port, it is characterized in that: calorifier links to each other with the heating duct that vertically stretches into simplified interior each section of oven dry, heating duct has two at least, heating duct near opening for feed is the longest, stretching into the heating duct length of drying cylinder body middle part takes second place, heating duct near discharge port is the shortest, the heating duct inner termination is connected with annular heat wind mouth, is evenly equipped with the eye of wind on the annular blowing mouth.
The hot blast volume damper is housed on the heating duct.
The revolution screening plant is made of endless metal net and discharge port, the mesh of wire netting varies in size, and is little near the mesh of dram, and the mesh size of screen cloth middle part is placed in the middle, big near the mesh at calorifier position, three kinds of mesh are corresponding with powdery, middle particulate material, macrobead material discharge port respectively.
Working process: moist material enters in the oven dry rotating cylinder from opening for feed, the hot blast mouthpiece that is arranged on this position blows out the higher hot blast of temperature, at first it is dried, when material moves to the middle part along with the rotation of drying rotating cylinder, the hot blast mouthpiece that is arranged on this position blows out the low slightly hot blast of temperature, it is proceeded drying, when material moves to screening plant, the hot blast mouthpiece that is arranged on this place blows out the lower hot blast of temperature, make material reach dry standard, pass through endless metal screen cloth sub-sieve then, make powder enter the powder discharge port, particulate material discharge port during middle particulate material enters, the macrobead material enters macrobead material discharge port.
The utility model has the advantages that and adopt the multitube segmentation to send hot blast, with volume damper control air output attemperation, and adopt annular heat wind mouth that material is dried, improved the rate of drying of material, reduced energy consumption, effectively solved in the bio-feritlizer drying course simultaneously the long technical barrier that reduces the microbiobacterial agent survival rate of, drying time too high because of bake out temperature.Be applicable to the oven dry and the screening of bio-feritlizer and composite fertilizer.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of annular heat wind mouth.
Fig. 3 is the side-view of Fig. 2.
As shown in Figure 1, bio-feritlizer oven dry sieve apparatus comprises drying cylinder body 1, opening for feed 2, induced draft fan 3, calorifier 4, three heating ducts 5, annular heat wind mouth 6, volume damper 7, revolution screening plant 8, powder discharge port 9, middle particulate material outlet 10, macrobead material outlet 11, power-driven gear 12, gear wheel 13, support roller 14, roller 15, calorifier is at discharge port one end, and links to each other with three heating ducts 5 with volume damper 7; Ring-type hot blast mouthpiece 6 is equipped with in the end of heating duct 5, is separately positioned in the middle of opening for feed 2, the dram 1 and screening plant 8 and three positions, dram 1 junction; Revolution screening plant 8 links to each other with oven dry simplified 1, screening plant 6 is made of endless metal screen cloth 16 and powder, middle particulate material, macrobead material discharge port 9,10,11, the mesh of metallic sieve 16 varies in size, mesh near dram 1 is little, the mesh size of screen cloth middle part is placed in the middle, big near the mesh at calorifier 4 positions, three kinds of mesh are corresponding with powder-material discharge port 9, middle particulate material discharge port 10, macrobead material discharge port 11 respectively.Be evenly equipped with the eye of wind 17 on the ring-type hot blast mouthpiece 6, as shown in Figures 2 and 3.
