Technical field
The present invention relates to a kind of atomising device, particularly relate to a kind of high-speed centrifugal atomization device for the dry production process of compound zirconia spraying.
Background technology
At present, the high-speed centrifugal atomization device for the dry production process of compound zirconia spraying generally comprises housing, atomizing disk, slurry dispenser, material pipe, rotating shaft and motor; Slurry dispenser is fixedly mounted on the lower ending opening place of housing, and slurry dispenser is provided with axis hole and material hole; Rotating shaft is in housing, the upper end rotatable (generally passing through bearing) of rotating shaft is arranged on the top of housing, expose in housing outside by the axis hole on slurry dispenser the lower end of rotating shaft, and atomizing disk is fixedly mounted on lower end the below in slurry dispenser of rotating shaft; Material pipe is in housing, and the material lower end of pipe and the material hole of slurry dispenser are connected, and the upper end of material pipe reaches housing outside by the top of housing; The upper end of motor and rotating shaft is in transmission connection.Wherein, housing, atomizing disk, slurry dispenser, material pipe substantially all adopt stainless steel material to make, motor drives atomizing disk High Rotation Speed by rotating shaft, the centrifugal force of generation by be injected into slurry (compound zirconia) in atomizing disk throw away go in high temperature drying tower body dry.
Because the slurry being injected in atomizing disk produces one-sided active force to atomizing disk, affect the dynamic balancing of atomizing disk; The slurry being injected in atomizing disk easily condenses on atomizing disk, also affects the dynamic balancing of atomizing disk; Simultaneously, because slurry dispenser is very little with the spacing of atomizing disk, and the slurry dispenser of stainless steel due to and housing between heat transmission and temperature is very high, backwash will soon condense to the slurry on slurry dispenser lower surface, cause and atomizing disk between produce friction, also affected the dynamic balancing of atomizing disk, thereby cause atomizing disk to lose dynamic balancing in the situation that of High Rotation Speed and damage, the efficiency and the stability that have a strong impact on equipment operation, often break down, and production efficiency is lower.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high-speed centrifugal atomization device, and the atomizing disk of this high-speed centrifugal atomization device has good dynamic balancing stability, stable, reduces fault, enhances productivity.The technical scheme adopting is as follows:
A kind of high-speed centrifugal atomization device, comprise housing, atomizing disk, slurry dispenser, material pipe, rotating shaft and motor, slurry dispenser is fixedly mounted on the lower ending opening place of housing, slurry dispenser is provided with axis hole and material hole, rotating shaft is in housing, the upper end of rotating shaft is rotatably arranged on the top of housing, expose in housing outside by the axis hole on slurry dispenser the lower end of rotating shaft, atomizing disk is fixedly mounted on lower end the below in slurry dispenser of rotating shaft, material pipe is in housing, the material lower end of pipe and the material hole of slurry dispenser are connected, the upper end of material pipe reaches housing outside by the top of housing, the upper end of motor and rotating shaft is in transmission connection, it is characterized in that: also comprise gas blowing device and tracheae, described slurry dispenser is provided with pore, and pore and described material hole are symmetricly set on the both sides of rotating shaft, tracheae is in housing, and the lower end of tracheae is connected with pore, and the upper end of tracheae reaches housing outside by the top of housing, and gas blowing device is connected with the upper end of tracheae.
Above-mentioned pore is symmetricly set on the both sides of rotating shaft with expecting hole, refers to that the line of centres in pore, material hole is by the axis of rotating shaft.
Owing to having set up gas blowing device, and pore and material hole are symmetricly set on the both sides of rotating shaft, by material hole be injected into the slurry of atomizing disk, the air that is ejected into atomizing disk by pore all produces active force to atomizing disk, these two active forces are symmetrical, therefore make atomizing disk when High Rotation Speed, keep good dynamic balancing; Not being atomized the air that the slurry on atomizing disk is injected into that remains in that dish throws away blows away; Backwash also can be blown away to the air on slurry dispenser by same backwash to the slurry on slurry dispenser lower surface, makes condense a large amount of reduce of slurry on atomizing disk, slurry dispenser, thereby makes the dynamic balancing of atomizing disk more stable; Therefore, the atomizing disk of this high-speed centrifugal atomization device has good dynamic balancing stability, stable, reduces fault, enhances productivity.
As preferred version of the present invention, it is characterized in that: described gas blowing device comprises the first valve, at least one air cleaner, pressure regulator valve and the second valve; The first valve, air cleaner, pressure regulator valve and the second valve are connected in series successively.Above-mentioned air cleaner filters air, and the air degree of purity that makes to be injected to atomizing disk is higher, with ensure quality requirement; The cooperation of the first valve, pressure regulator valve and the second valve, by the adjusting to pressure regulator valve, make gas with slurry, the active force of atomizing disk be equated as far as possible, compressed air passes into from the first valve, by the second valve, sprayed after filtering, thereby make the suffered external force of atomizing disk balance more, make atomizing disk when High Rotation Speed, keep good dynamic balancing.Generally, the two poles of the earth air cleaner need to be set, the filtering accuracy of first order filter is 1um, and the filtering accuracy of second level filter is 0.01um, makes filtered compressed air have higher degree of purity.
As the further preferred version of the present invention, it is characterized in that: also comprise that Pressure gauge, Pressure gauge are arranged on the first valve place.By the reading on Pressure gauge, more easily by control valve, the pressure that sprays into air is adjusted to identical with the pressure that injects slurry.
As further preferred embodiments of the present invention, it is characterized in that: it is 0.14～0.32W/m.K(watt every meter every Kelvin that described slurry dispenser adopts pyroconductivity) low thermal conductivity material make.Further preferably low thermal conductivity material is polytetrafluoroethylene (PTFE), and further the pyroconductivity of preferably polytetrafluoroethylene is 0.24W/m.K.The slurry dispenser of being made by polytetrafluoroethylmaterial material, because the pyroconductivity of polytetrafluoroethylmaterial material is far below stainless steel, the temperature on the slurry dispenser surface of therefore being made by polytetrafluoroethylene (PTFE) is more much lower than the slurry dispenser of originally making of stainless steel, so backwash can not condense at once to the slurry on slurry dispenser, through backwash to the air blown on slurry dispenser, the solid condensing on slurry dispenser will reduce a lot, thereby further reduced the friction of slurry dispenser due to condensing of slurry and between atomizing disk, further make atomizing disk there is good dynamic balancing.
