Abstract
The invention discloses a method and a device for controlling the moderate heat cement temperature. The method comprises that cement entering the lower portion inside a cooling cylinder is continuously stirred through rotation of spiral conveying blades, full heat exchange between the cement and cooling water outside a vertical wall of the cooling cylinder is achieved through the vertical wall, simultaneously, the cement is lifted from the lower portion of the cooling cylinder to the upper portion of the cooling cylinder, and finally, the cement is discharged out of the cooling cylinder through a discharging port. The device comprises the cooling cylinder, a power driving device, an immersing cylinder, a cooling water sleeve, a water curtain device and the like, wherein a charging port and the discharging port are arranged on the cooling cylinder, spiral conveying blades are arranged in the middle inside the cooling cylinder, the power driving device of spiral conveying blades is arranged outside the cooling cylinder, the immersing cylinder and the cooling water sleeve are arranged outside the vertical wall of the cooling cylinder, and the water curtain device is arranged on the circumference of the outer wall at the top of the cooling cylinder. Compared with the prior art, the method and the device have the advantages that the problem that the cement warehousing temperature is too high during production of the moderate heat cement by original cement production devices is solved.
Description
Technical field
The invention belongs to building material technical field, particularly relate to a kind of moderate heat cement temperature-controlled process and equipment.
Background technology
In the cement production process flow process that my company was traditional in the past, cement arrives the operations such as grinding through raw material again to grog, and when going out to grind, cement temperatures is generally at 130 DEG C, sometimes up to 135 DEG C, directly enter cement silo finally by various conveying equipment cement, cement temperatures during warehouse-in is at about 100 DEG C.Along with the development of society, novel building emerges in an endless stream, also more and more higher to the requirement of Cement Quality accordingly.In nuclear power station or large hydropower station etc. are built, in order to reduce internal-external temperature difference stress, prevent reactor or dam cracking, the normal lower cement of hydration heat that uses is poured into a mould, therefore, start to produce moderate-heat portland cement (calling moderate heat cement in the following text) in enormous quantities according to my company of market demand.But the cement temperatures during manufacturing technique requirent of this cement warehouse-in must be less than or equal to 60 DEG C, therefore, utilize my company's existing equipment to produce moderate heat cement just to need to go out between mill and cement warehouse-in at cement, by cement temperatures control method and the equipment of increase, cement temperatures when putting in storage is made to control within manufacturing technique requirent, be less than or equal to 60 DEG C.
Summary of the invention
The invention provides a kind of moderate heat cement temperature-controlled process and equipment, it can solve the too high problem of temperature of cement warehouse-in when original cement manufacture plant produces moderate heat cement.
In order to solve the problem, the technical solution adopted in the present invention is: this moderate heat cement temperature-controlled process, includes the cement that need cool and enters in described cooling cylindrical shell from the charging aperture of cooling cylindrical shell bottom; Constantly stir by the rotary motion being arranged on the spiral conveying blade vertically extended in described cooling cylindrical shell, promote described cement, make it be expressed to the inwall of described cooling cylindrical shell, thus make described cement be thus lifted to the chilled water spread all over the outer wall that is arranged on described cooling cylindrical shell the process on the top of described cooling cylindrical shell from the bottom of described cooling cylindrical shell fully to carry out heat interchange; Finally, described cement is discharged from the discharging opening on described cooling cylindrical shell top.
In the technical scheme of above-mentioned moderate heat cement temperature-controlled process, technical scheme can also be more specifically: the rotational speed of described spiral conveying blade is 72-76 rpm; The temperature of described chilled water, summer is 28 DEG C--30 DEG C, winter is 16 DEG C-20 DEG C.
This moderate heat cement Temperature-controlled appliance, include a cooling cylindrical shell, the bottom of described cooling cylindrical shell is provided with charging aperture, the top of described cooling cylindrical shell is provided with discharging opening, the spiral conveying blade being provided with vertically extension in described cooling cylindrical shell, described spiral conveying blade drives by being arranged on the external actuating unit of described cooling cylinder; The bottom of described cooling cylinder body outer wall is set with the immersion cylinder that there is opening a upper end, it is funnelform cooling jacket that the middle part of this cooling cylinder body outer wall is set with an open upper end, the upper end open of described immersion cylinder is communicated with the lower end of described cooling jacket, be provided with water inlet in the bottom of described immersion cylinder, the top of described cooling jacket is provided with water delivering orifice; Top exterior walls near described cooling cylindrical shell above described cooling jacket is circumferentially provided with water screen apparatus.
In the technical scheme of above-mentioned moderate heat cement Temperature-controlled appliance, technical scheme can also be more specifically: described water inlet and described water screen apparatus are all communicated with cooling water inlet pipe.
Owing to adopting technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention controls within the scope of technological requirement by taking cooling provision and increase cooling device that cement is entered warehouse temperature.
2, structure of the present invention is simple, good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present invention.
