:,(54) УСТАНОВКА ДЛЯ ГРАНУЛЯЦИИ СИЛИКАТНЫХ РАСПЛАВОВ:, (54) INSTALLATION FOR GRANULATION OF SILICATE MELTS

Изобретение относьтс к установке aria гранул ции сйликатнь х расплавов и может быть использовано в промышленности строительных материалов и химической промышленности при переработке металлургичесхих и химических расплавов и шлаков в гра нулированный шлак и шлаковую пемзу.The invention is related to the installation of aria granulation of melted melts and can be used in the building materials industry and the chemical industry in the processing of metallurgical and chemical melts and slags into granulated slag and slag pumice.

Известна устаиовка с воздушным гранул тором и приемной тракшеейдл производства гранулированного шлака и зернистой шлаковой пемзы l.Famous installation with an air granulator and a traccheidle for the production of granulated slag and granular slag pumice l.

Известны ..также установки с вращаюшимис барабанами дл производства плотного или пористого, зернистого заполнител бетонов , в частности, шлаковой пемзы 23Однако такие установки характеризуютс плохим улавливанием и отводом неусвоенной технологической .воды, что ведет к получению влажного продукта, нуждающегос в последующем высушивании. Известна установка, содержаща врашаюшийс барабан с продольными ребрами на внутренней поверхности, поперечной коль иевой перегородкой н -асположенными под ней водоотводами з. При работе такой Known installations are also known with rotatable drums for the production of dense or porous granular aggregates of concrete, in particular, slag pumice. However, such installations are characterized by poor trapping and removal of undisturbed process water, which leads to a wet product that needs further drying. A device is known that contains a rotating drum with longitudinal ribs on the inner surface, a transverse ring septum and drainage pipes located under it. When working such

Цель изобретени - снижение уноса с водой мелких частиц, образующихс при гранул ции шлакового расплава.The purpose of the invention is to reduce the entrainment of fine particles with water resulting from the granulation of a slag melt.

, Дл Этого заборные части воарртводов выступают над внутренней поверхностью барабана, а продольные ребра выполнены перфорированными.For this purpose, the intake portions of the warrtvods protrude above the inner surface of the drum, and the longitudinal ribs are perforated.

Установка включает водовоздушный гранул тор 1, конец которого проходит через |торповый щит 2 и аходит внутрь загрузочной части вращающегос барабана 3, гимеюшего уклон в сторону разгрузочной части. Ось-водовозпушного гранул тора и ось барабана наход тс в одной вертикальной плоскости.The installation includes a water-air granulator 1, the end of which passes through the torped shield 2 and goes inside the loading part of the rotating drum 3, which slopes towards the unloading part. The axis of the water inlet pellet and the axis of the drum are in the same vertical plane.

Claims

Inside the drum 3 there is an annular partition 4, in front of which on the side facing the loading end of the drum there are intake parts of the drainage system 5, They protrude inwards to a height smaller than the height of the wall of the ring section. Longitudinal perforating ribs 6 are located on the same side of the collar partition. Outside the drum, the drainage holes are covered with a small gap by a fixed annular chamber 7, to the bottom of which the drain pipe 8 is attached, and to the upper side there is a gas exhaust pipe 9. The discharge end of the drum is enclosed in the receiving chamber 10, to which the gas-discharge duct 11 adjoins. From the bottom, the receiving chamber passes the discharge bunker 12. The slag melt entering the water-air granule — torus is expanded and dispersed. It is also dispersed / process water1. The air flow carries particles of slag and undigested water into the rotating drum. Due to the dramatic expansion, the air flow rate drops rapidly. Thanks to this, lighter and smaller, less inertial, water particles mostly settle near the outlet from the water-air granulator before the annular partition 4. A small amount of slag particles is also deposited here. The main part of heavier and larger slag particles with greater inertia is deposited further, on the other side of the annular partition 4. Due to the inclination of the drum O, water flows to the partition, which retards its further movement, and granular slag pumice behind the partition 4 moves unhindered to the discharge end of the drum. Gradually, the water level accumulating with in front of the partition increases, and it is poured into the inside of the inward trunk honor BOfloOTbOflpEj 5. More; heavy slag particles are below water level. The longitudinal ribs 6 continuously remove slag particles from the water and, due to the slope of the drum 3, throw them through the annular partition 4. This is facilitated by the air flow directed along the slope of the drum. Due to the fact that the ribs 6 are perforated, the slag particles rise and only the water that wets them is carried away. The remaining water flows down and flows out; through drainage systems. Thus, behind the partition 4, the still hot and dry particles of slag and particles of slag moistened with water are mixed. Due to the fact that the former are much larger than the latter and that the latter carry away a relatively small amount of water, it is completely evaporated. As a result, a dry product enters from the drum 3 into the receiving chamber 10 and further into the hopper 12. The water flowing out through the drainage systems collects inside the annular chamber 7 and flows out through the drain pipe 8. The vapors and gases that pass through the drainage systems when they are above the water level are removed through the vapor pipe 9. The remaining vapor and gases gather in the receiving chamber. and removed along a vapor outlet duct 11. Claims An apparatus for the granulation of silicate melts comprising a rotating drum with a mounted drum. its inner surface. longitudinal ribs. - XI, characterized in that, in order to reduce the water entrainment of small planks, formed during the granulation of the slag melt, the intake parts of the outlet pipe protrude above the inner surface of the drum, and the longitudinal ribs made perforated.
