Description
Обычно определение гранулометрнчсского состава несков и т. п. материалов существующим методом требует сложного лабораторного оборудовани , трудоемких и длнтсльных нроцессов исследовани .Usually the determination of the granulometry of the neskov, etc. materials by the existing method requires sophisticated laboratory equipment, laborious and long-term research processes.
В предлагаемом способе и приборе дл мокрого фракционировани песков и т. н. материалов указанные недостатки устранены тем, что пробу исследуемого материала загружают в прибор с несколькими коническими ситами, пемещеннымн в цилиндрический корпус, укрепленный на поплавке, плавающем в сосуде с жндкостью так, чтобы 100 деление шкалы прибора было на уровне жидкости, в которую погружен поплавок.In the proposed method and an apparatus for the wet fractionation of sands, and so on. These deficiencies are eliminated by the fact that the sample of the material under investigation is loaded into a device with several conical screens, placed in a cylindrical case, mounted on a float floating in a vessel with a tank so that the scale of the device is 100 times the level of the liquid in which the float is immersed.
Цилиндрический корпус в процессе фракционировани ирнводнтс во вращательное движение и носле осаждени различных фракций на соответствующих ситах вымывают поочередно снизу отдельные фракции . Это достигаетс посредством дисков с отверсти ми, которые укреплеиы в центре каждого сита. Отверсти дисков перекрыты осевым стержнем, подвижным в вертикальном направлении. Открыва поочередио (снизу) отверсти в дисках, вымывают осевипю на данном сите фракцию. После вымывани каждого из сит, прибор времешю иереноситс в сосуд с чистой водой и но мере увеличени размера его всплывани на шкале определ етс процентное содержание каждое фракции в пробе.The cylindrical body in the process of fractionation of the irregulars into rotational motion and carrying out the deposition of various fractions on the corresponding sieves, alternately elute the separate fractions from the bottom. This is achieved by means of discs with holes that are reinforced in the center of each screen. The holes of the discs are covered with an axial rod that moves in the vertical direction. Opening alternately (from below) the holes in the disks, wash out the fraction with osevipyu on this sieve. After each of the sieves is washed out, the device will be transferred to a vessel with pure water, but as the size of its float increases on a scale, the percentage of each fraction in the sample is determined.
Такое устройство упрощает процесс определенп гранулометрического состава песков, позвол обойтись без вспомогательной аннаратуры и расчетов пеносредственно в нолевых услови х или на стройке.Such a device simplifies the process of determining the granulometric composition of sands, making it possible to do without ancillary annotations and calculations directly under zero conditions or at a construction site.
На чертеже схематически изображено предлагаемое устройство.The drawing schematically shows the proposed device.
Цилиндрический корпус / с несколькими коническими ситами 2 установлен на поплавке 3, снабженном трубкой 4 со шкалой 5, градуированной в процентах.The cylindrical body / with several conical sieves 2 is mounted on the float 3, equipped with a tube 4 with a scale of 5, graduated in percentage.
В центре каждого сита укреплен диск 6 с отверстие м.In the center of each screen there is a reinforced disk 6 with a hole of m.
Осевой стержень 7, подиижной в вертикальном направлении вставлен в отверсти дисков и открывает их, с целью ноочередного вымываин фракний, осевн1их на соответствующих ситах.An axial rod 7, podizhnoy in the vertical direction is inserted into the holes of the discs and opens them, with the aim of a new washout of fractions, which are axially fixed on the corresponding sieves.
Испытуемый песок н т. н. материал насыпаетс к прибор сверху через трубку 8 п)и закрытых отверсти х дисков осевым стержнем 7.Test sand n. The material is poured into the device from above through the tube 8 p) and the closed holes of the disks with an axial rod 7.
Прибор загрузке пеггытуемого материала находитс в сосуде 9 с жидкостью п погружаетс до 100 делени шкалы 5. Таким путем отбираетс проба, дающа на пгкале 100%. Далее по щкале беретс отсчет пропентного содержани фракпгп каждого сита.The device for loading the pulverized material is in the vessel 9 with liquid n immerses up to 100 divisions of the scale 5. In this way, a sample is taken which gives 100% on the plate. Further, the scale of the fractional fraction of each sieve is taken along the scale.
