The specific embodiment
As Figure 1-4, a kind of mica calciner cooling tower, comprise cooling column body 30, cooling column body 30 tops are provided with Yi Ge spray head mechanism 2, it is conical that described cooling column body 30 tops are, described comprises by upper cover plate 21, the shower tray that is truncated cone 20 that lower cover 22 and side plate 23 surround, shower tray 20 inside are hollow structure, can storage of water, upper cover plate 21 is provided with spray water inlet pipe 24 and spray water inlet pipe 24 extends to shower tray 20 inside, described shower tray 20 is provided with the feeding cylinder 25 that is cylindricality, feeding cylinder 25 is preferably cylindric, described feeding cylinder 25 runs through upper cover plate 21 and lower cover 22 and extends cooling column body 30 tops, on described lower cover 22, be densely covered with shower water outlet 221, shower water outlet 221 can be that various shapes are as circle, polygon etc.When work, mica enters from feeding cylinder 25, shower water first enters into shower tray 20 inside from spray water inlet pipe 24, again from shower water outlet 221 ejections, because feeding cylinder 25 is located in shower tray 20, from feeding cylinder 25 mica out, all drop in the coverage of shower water outlet 221, thereby by cooling in time.The bottom sidewall of described cooling column body 30 is provided with a washings water inlet pipe 31, the sidewall of cooling column body 30 is provided with a mica discharging opening 32 and described mica discharging opening 32 is positioned at washings water inlet pipe 31 tops, washings water inlet pipe 31 passes into rinsing water, be generally water for industrial use as running water, because the density ratio water of mica is little, therefore swim on the water surface, and the density ratio water of sandstone is large, therefore sink to the bottom, rinse cycle is separated with sandstone according to large young pathbreaker's mica of density, in cooling to mica, also realized purification, thereby alleviate the pressure of subsequent handling, operating efficiency is provided.
The air intake that cooling column body 30 tops are also connected with an induced duct 33 and this induced duct 33 is positioned at spray head mechanism 2 belows, described induced duct 33 connects the air-introduced machine 34 that can produce negative pressure, the negative pressure that air-introduced machine 34 produces makes mica be inhaled into from feeding cylinder 25, certainly, feeding cylinder 25 can connect mica treatment process above by airduct.
Conventionally, in mica, can mix impurity such as there being sandstone, after mica calcining, having one special operation is that sandstone is separated with mica, thereby improve the purity of mica, in the present embodiment, cooling column body 30 inside between washings water inlet pipe 31 and mica discharging opening 32 are also provided with a screen pack 35 that can allow water see through, this screen pack 35 is separated with mica by sandstone, the bottom of described cooling column body 30 is provided with a sandstone discharge gate 36 that can open and close, after sandstone is separated with mica, sandstone can be discharged from sandstone discharge gate 36.As preferably, screen pack 35 is that stainless steel screen pack and aperture are between 20-40 order.
As a kind of preferred scheme, shower water outlet in the present embodiment 221 is radial arrangement on lower cover 22, thereby generation center is intensive, and around the distribution of loose spray water column, further promotes cooling effect.
On upper cover plate 21, be installed with and have flexible hitch 26, this hitch 26 makes the present invention be suspended on the top of cooling tower by the mode hanging.Hitch 26 comprises some spring parts 261, described spring part 261 is regular polygon and is arranged in upper cover plate 21 surfaces and affixed with upper cover plate 21, the distribution of above-mentioned spring part 261 makes shower tray 20 stressed evenly, be convenient to install to hang and held stationary in use, spring part 261 can be selected spring, also can select and have flexible rope.Preferably, spring part 261 is cylindrical spring.
On side plate 23, be embedded with sealing ring 27 and sealing circle 27 outstanding side plate 23 surfaces.When hitch 26 is suspended on cooling tower top by shower tray 20, because hitch 26 has elasticity, therefore shower tray 20 upwards can be promoted automatically, make sealing ring 27 and the laminating of cooling tower inwall, reach sealing effectiveness.Preferably, sealing ring 27 is teflin ring, and polytetrafluoroethylene (PTFE) can be high temperature resistant and not perishable, so service life is longer.Above-mentioned scheme, closely cooperates spray head mechanism 2 and the top of cooling column body 30, thereby plays the effect of sealing, and negative pressure can not revealed.
The total course of work of the present invention is as follows: during air-introduced machine 34 work, produce negative pressure, by induced duct 33, make the inner negative pressure that produces of cooling column body 30, thereby mica is sucked from feeding cylinder 25, shower water mechanism 2 produces the spraying cooling water that can cover whole cooling column body 30 inside, the mica sucking is carried out to cooling down, 31 pairs of cooled micas of washings water inlet pipe carry out rinsing, the sandstone precipitation mixing in mica is removed, mica after rinsing is discharged from mica discharging opening 32, and cooling, the rinsing, purification one step that realize mica complete.Operating efficiency of the present invention is high, energy consumption is low and can significantly reduce the pressure of subsequent handling.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although more used the terms such as spray head mechanism 2, shower tray 20, upper cover plate 21, lower cover 22, side plate 23, spray water inlet pipe 24, feeding cylinder 25, hitch 26, sealing ring 27, shower water outlet 221, spring part 261, cooling column body 30, washings water inlet pipe 31, mica discharging opening 32, induced duct 33, air-introduced machine 34, screen pack 35, sandstone discharge gate 36 herein, do not got rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present invention, they are construed to any additional restriction is all contrary with spirit of the present invention.
