Abstract

Использование; подготовка дл  пластического формовани  керамической массы. Сущность изобретени : на съемной ступице, установленной на валу шнекового смесител  за наружной поверхностью его решетки, ра- диально расположены изогнутые режущие ножи. Ножи наклонены к решетке в месте креплени  к ступице под углом 75°, а у свободных краев - под углом 15°. 2 з.п. ф-лы, 7 ил.Using; preparation for plastic molding a ceramic mass. SUMMARY OF THE INVENTION: on a removable hub mounted on a shaft of a screw mixer behind an outer surface of its grill, curved cutting knives are radially arranged. The knives are inclined to the grill at the attachment point to the hub at an angle of 75 °, and at the free edges, at an angle of 15 °. 2 s.p. f-ly, 7 ill.

Description

Изобретение относитс  к устройствам дл  гранул ции керамической массы. Устройство размещаетс  непосредственно за решетчатой пластиной вакуумного пресса, примен емого в керамической промышленности и раздел ет выход щие из решетчатой пластины шнуры массы на короткие отрезки. Применение изобретени  даетс  тем самым дл  керамической промышленности .The invention relates to devices for granulating a ceramic mass. The device is placed directly behind the trellis plate of the vacuum press used in the ceramic industry and separates the mass cords exiting the trellis plate into short segments. The application of the invention is thus provided for the ceramic industry.

Целью изобретени   вл етс  расчетное разделение выход щих из решетчатой пластины шнуров массы внутри вакуумной камеры шнекового пресса.The aim of the invention is the calculated separation of the mass cords emerging from the grating plate within the vacuum chamber of the screw press.

На фиг. 1 показано устройство в частично разрезанном прессе, вид сбоку; на фиг.2 - то же, вид спереди; на фиг.З - режуща  звездочка; на фиг.4-6 - разрез А-А, Б-Б, В-В на фиг.З; на фиг.7 - режущий нож без учета его установочного угла.In FIG. 1 shows a device in a partially cut press, side view; figure 2 is the same front view; Fig. 3 - cutting asterisk; figure 4-6 is a section aa, bb, bb in figz; Fig.7 - cutting knife without taking into account its installation angle.

На фиг. 1 схематически представлено соответствующее изобретению устройство. Как видно из чертежа, размещенный в сме- сительном корыте 1 смесительный вал 2 снабжен смесительными лопаст ми 3.In FIG. 1 schematically shows a device according to the invention. As can be seen from the drawing, the mixing shaft 2 located in the mixing trough 1 is equipped with mixing blades 3.

Смесительный вал 2 проходит сквозь расположенную в смесительном корыте 1 решетчатую пластину 4 и имеет на конце режущую звездочку. Последн   состоит по сути из ступицы 5, котора , в свою очередь, оснащена несколькими режущими ножами 6. Соединение режущей звездочки со смесительным валом 2 происходит с помощью винта 7, и таким образом, выполнено разъемным , причем за счет не показанных на фиг.1 прокладок, рассто ние между режущими ножами 6 и решетчатой пластиной 4 может устанавливатьс  различным.The mixing shaft 2 passes through the grid plate 4 located in the mixing trough 1 and has a cutting sprocket at the end. The latter consists essentially of a hub 5, which, in turn, is equipped with several cutting knives 6. The cutting sprocket is connected to the mixing shaft 2 by means of a screw 7, and thus is made detachable, due to the gaskets not shown in Fig. 1 , the distance between the cutting knives 6 and the grid plate 4 can be set different.

На фиг.2 показано размещение режущих ножей 6, здесь, например, шесть штук. которые направлены радиально и образуют вместе со ступицей 5 режущую звездочку.Figure 2 shows the placement of the cutting knives 6, here, for example, six pieces. which are directed radially and form together with the hub 5 a cutting sprocket.

На фиг.3-6 подробнее разъ снено выполнение режущих ножей 6. Последние расположены на ступице 5 так, что со стороны основани  образуют установочный угол 30° относительно оси ступицы 5. Этот установочный угол равномерно увеличиваетс  к свободному концу режущего ножа до значеFigures 3-6 explain in more detail the implementation of the cutting knives 6. The latter are located on the hub 5 so that from the base side they form an installation angle of 30 ° relative to the axis of the hub 5. This installation angle increases uniformly to the free end of the cutting knife to

ни  около 60° (фиг.4-6), так что нож тем самым выполнен слегка спиральным.not about 60 ° (Figs. 4-6), so that the knife is thereby made slightly spiral.

За счет различного количества режущих ножей 6 возможно оказывать вли ние на свободный проход решетчатой пластины 4.Due to the different number of cutting knives 6, it is possible to influence the free passage of the grating plate 4.

Как видно из фиг.7, режуща  кромка режущего ножа 4 заточена под углом преимущественно в 45°.As can be seen from Fig.7, the cutting edge of the cutting knife 4 is sharpened at an angle mainly of 45 °.
