Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of cement additire process units, including calcining furnace 1, drying channel 2 and air-introduced machine 3, it is described
Connected between air-introduced machine 3 and calcining furnace 1 by drying channel 2, the drying channel 2 from close to one end of calcining furnace 1 to remote
One end of calcining furnace 1 is tilted down, and the middle part of drying channel 2 is arranged with gear wheel 4, and the lower section of gear wheel 4 is correspondingly arranged
There is motor 5, be connected by reductor 6 between the motor 5 and gear wheel 4, set inside the drying channel 2
There is paddle.
Specifically, the both ends of gear wheel 4 are respectively equipped with support ring 7, and two support rings 7 are set on drying channel 2,
The lower section of support ring 7 is correspondingly arranged on support component, and the support component includes support platform 8 and is arranged on support platform 8
On two rollers 9, two rollers 9 are symmetrical on support ring 7 and two rollers 9 are rolled with support ring 7 and connected.
A kind of production technology using above-mentioned cement additire process units, comprise the following steps：
1) industrial waste raw material is subjected to sampling chemical examination, obtains the content value of sulfur trioxide in raw material.
2) when the content of sulfur trioxide in raw material is less than %35, then sulfur trioxide is added in the feed so that in raw material
The content of sulfur trioxide is more than 35%, obtains standard raw material；When the content of sulfur trioxide in raw material is more than %35, then directly
Used as standard raw material.
3) standard raw material are put into and 3-5 minutes is calcined in calcining furnace 1.
4) the standard raw material after calcining are sucked into drying channel 2 by air-introduced machine 3, while starts motor 5, driven
Drying channel 2 is rotated, and paddle is stirred to the standard raw material in drying channel 2.
5) the standard raw material after drying by transmission belt blanking and are packed.
Specifically, the temperature in the calcining furnace 1 is 800-1100 DEG C.
Specifically, the drying time of the standard raw material is 20-30 minutes, and drying temperature is 200 DEG C, drying channel 2
The temperature of interior close calcining furnace one end is 400-500 DEG C, and the temperature in drying channel 2 close to the one end of air-introduced machine 3 is 90-100 DEG C.
Specifically, the raw material is titanium gypsum or ardealite, desulfurated plaster.
In fact, the error containing sulfur trioxide is ± 2% in raw material.
In fact, cement additire of the present invention is the cement retarder in industrial production.
By the Control for Kiln Temperature of calcining furnace 1 between 800-1100 DEG C, and by drying time control 20-30 minutes it
Between, primarily to the content of the crystallization water and attached water in control material.In this calcining heat and the section model of drying time
In enclosing, it can ensure that the content of the crystallization water is not less than 16%, ensure condensation degree, so as to avoid that the phenomenon of false set occurs；At this
In the interval range of individual calcining heat and drying time, it can ensure that the content of attached water is less than 15%, ensure the drying of material
Property, prevent that material is difficult to be molded because of overly moist, cannot get target product.
While sulfur trioxide content is tested, the humidity of raw material can be also tested, when raw material humidity is more than 40%, is then marked
Quasi- raw material need drying 30 minutes in drying channel 2；When raw material humidity is less than 30, then standard raw material need drying
Drying 20 minutes in passage 2；The final moisture content of drying is 15%.
Standard raw material are put into calcining furnace 1 and calcined, primarily to going the removal of impurity.
When drying channel 2 rotates, the paddle in drying channel 2 can be stirred the standard raw material of inside
Mix, and cause underlying standard raw material to reach the inner upper of drying channel 2, due to the suction of air-introduced machine 3, drying
Standard raw material in passage 2 rise to decline during this in experience, can towards air-introduced machine 3 one section of an end movement away from
From, so circulation, realize the purpose that standard raw material are transferred to the other end from one end of drying channel 2, and this displacement
Speed it is directly proportional to the rotating speed of drying channel 2, i.e. velocity of displacement of the standard raw material in drying channel 2 and motor 5
Rotating speed it is directly proportional, can by control the rotating speed of motor 5 control standard raw material in drying channel 2 drying when
Between, and in this process, due to the rotation of drying channel 2, effectively standard raw material can be molded, final
To granular material.
Compared with prior art, the cement additire process units and its production technology, can be by trade waste titanium gypsum
Refuse reclamation is carried out with ardealite, desulfurated plaster, the space of waste occupancy is saved, reduces pollution, it is also possible that useless
Gurry is fully utilized, and avoids the waste of resource.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
