Abstract

FIELD: mechanics.

SUBSTANCE: granulator scrubber mechanism is made up of two independent pieces. The scrubber mechanism represents, on the bath horizontal section, a frame articulated, at four points, to two pairs of discs symmetrically arranged on two parallel axles. The scrubbers are attached to the frame on the bath side, the spacing between them not exceeding the diameter described by the scrubber hinge. Note here that the vector of speed of the scrubber lowest point is directed parallel to the bath bottom, towards the glass stock unloading side. On the bath inclined section the scrubber mechanism represents two parallel axles supporting two pairs of sprockets of the chain conveyor that carries the scrubbers. The aforesaid horizontal section bottom represents a dual-layer structure with a gap between the said layers, the horizontal section end being furnished with a pit.

EFFECT: higher efficiency of granulation, improved labor conditions.

Description

The invention relates to a device for processing waste glass production and can be used to obtain granulate from a melt of material, in particular in the glass industry for the repair of glass furnaces or in the production of building materials.

Known granulator of glass melt, containing an inclined swinging tray, a melt separator, a falling device and a discharge funnel [1].

In addition, a granulator of glass melt is known, containing a bath with coolant, in the upper part of which are installed rotating rollers, and inside the bath there is a scraper conveyor for extracting glass melt [2].

A common disadvantage of the above devices is their low reliability, which leads to additional material and physical costs.

The objective of the invention is to remedy these disadvantages, that is, increase the efficiency of the formation of granulate, the reliability of the granulator, improve the working conditions of staff and save material and physical costs.

The technical result, which consists in eliminating these shortcomings in a granulator of glass melt containing a receiving tray, a bath with coolant and a scraper mechanism, is achieved due to the fact that the scraper mechanism is made of two independent parts:

on the horizontal section of the bath, the scraper mechanism is made in the form of a frame pivotally connected by four points with two pairs of discs symmetrically mounted on two parallel axes, to which scrapers are fixed on the side of the bottom of the bath with a step of no more than the diameter of the connection described on the hinge located on the disks, this speed vector of the lowest point of the scrapers is directed parallel to the plane of the bottom of the bath in the direction of unloading the glass;

on the inclined section of the bath, the scraper mechanism is made in the form of two parallel axes on which two pairs of sprockets are symmetrically fixed, carrying a chain conveyor with scrapers fixed to it.

In addition, the bath at the end of the horizontal section on the unloading side of the molten glass is provided with a pit, and the bottom of the bath is double, between which there is a gap, while the control system for the drive of the scraper mechanism in the horizontal section of the bath is equipped with an automatic control unit containing a sensor mounted on the drive frame, and a disk with a protrusion mounted on one of the drive axles so that, when interacting with the sensor, it stops the drive in a predetermined position, in this case, the location of the hinges di skov in the top dead position.

The invention is illustrated by drawings, where:

- figure 1 General view of the granulator glass;

- in figure 2, view A in figure 1;

- figure 3 section BB in figure 2;

- figure 4 is a structural diagram of the drive control.

The proposed granulator of the glass melt (Figs. 1-3) consists of a bath 1 filled with a cooling liquid of the receiving tray 2, through which the molten glass flows into the bath 1. In this case, the bath 1 has a horizontal section in the glass loading zone and an inclined one in the discharge zone.

The horizontal section has a double bottom, the upper of which is made in the form of a trough 3. At the end of the horizontal section, from the glass-unloading side, the bath 1 is equipped with a pit 4. The scraper mechanism is made of two independent parts: on the horizontal section of the bath 1, the scraper mechanism is made in the form of a frame 5, connected by four hinges 6 with disks 7, which are mounted symmetrically on two axes 8. In this case, disks 7 are made in the form of sprockets that are pairwise connected by a chain link 9. From the bottom of the bath 1 to the frame 5 s is defined scrapers 10 are fixed at this step.

The frame 5 is moved through the chain link 9 by the drive 11. On the inclined section of the bath 1, the scraper mechanism is made in the form of two parallel axes: the leading 12 and the driven 13, on which two pairs of sprockets 14, 15 are symmetrically mounted, carrying a chain conveyor 16 with fixed to it with scrapers 17.

The movement of the chain conveyor 16 is provided by the drive 18.

The drive control system (SOUP) 19 (Fig. 4) consists of a power supply unit (PSU) 20, a control unit (BU) 21, an automatic drive control unit (BAU) 22, including a sensor 23 and a disk 24 with a protrusion. When this sensor 23 is mounted on the frame of the actuator 11, and the disk 24 on one of the axes 8.

The device operates as follows. In the horizontal section of the bath 1 through the drive 11 through a chain link 9, the rotation of the sprockets 7, coupled on the axles 8, which are pivoted 6 by the hinges 6, rotates the frame 5 with the scrapers 10: on the inclined section of the bath 1 through the drive 19 of the axes 12, 13, of which the sprockets 14, 15 are fixed in pairs, movement is conveyed to the chain conveyor 16 carrying the scrapers 17.

The molten glass melt in the form of a jet or droplets enters the receiving tray 2 from the furnace and enters the bath 1 filled with coolant, in this case water, where due to the large temperature difference, the glass melt is intensively broken into granules. In order to more efficiently cool the molten glass, the bath 1 has a double bottom on a horizontal section, the upper of which is made in the form of a groove 3, washed from all sides with cooling water. In addition, when moving the hinges 6 from the upper dead position (IMF) to the lower dead position (IMF), the scrapers 10, mounted on the frame 5, carry out additional mechanical destruction of the glass melt and shift it towards the pit 4. Due to the fact that the scrapers 10 mounted on the frame 5 with a step less than the diameter described by the hinges 6, the granules move step by step along the entire plane of the horizontal bottom of the bath 1 to the pit 4, from which the granules are captured by the scrapers 17 of the chain conveyor 16 and move along an inclined section bath 1 to the zone of their removal beyond the granulator.

The drive control circuit (SOUP) 19 (figure 4) ensures the operation of the device in continuous mode and in cyclic mode. In this case, by means of the unit (BAU) 22, the drive 11 is stopped in a predetermined position. When you turn off the control unit (BU) 21 in any position of the actuator 11 (figure 4), except emergency, the actuator 11 will move from the power supply unit (BP) 20 through the automatic control unit (BAU) 22 until the protrusion of the disk 24 and the sensor 23 will not be on the same axis. In this case, this will correspond to the location of the hinges 6 in the upper dead position (VMP). This ensures that the starting torque of the drive 11 is reduced, especially in the cyclic mode of its operation, and energy savings are achieved.
