Description

TECHNICAL FIELD OF USEFUL MODEL

The present technical solution relates to technical means for grinding with drum mills, the drum of which is loaded with material that is crushed using special elements, for example, pebbles, balls, etc.

LEVEL OF TECHNOLOGY

A mill with a submersible bead basket is known (the brochure is published on the manufacturer's website https://www.netzsch-grinding.com/ru/produkty-i-reshenija/zhidkoe-izmelchenie/melnica-s-pogruzhnoi-korzinoi-mastermill/, file location https : //d2brmtk65c6tyc.cloudfront.net/media/grinding/brochures/12_Wet_Grinding/NETZSCH_MasterMill_RUS.pdf, published 07.2017, accessed 08.12.2020), which contains

working body, including a bead basket, made with the possibility of placing in a bowl;

stirrers of the bead mill, made with the possibility of placing in the bowl;

a lid capable of closing the bowl;

fixed head of the bead mill;

wherein

the bead basket is located on the vertical shaft of the bead basket with the ability to move in the vertical direction;

the agitators are located on the vertical shafts of the agitators with the ability to move in the vertical direction;

the shafts of the stirrers and the shaft of the bead basket are connected to the head of the bead mill;

the cover contains holes corresponding in position and shape to the shafts of the stirrers and the shaft of the bead basket, while the cover is movable in the vertical direction along the shafts.

In the known solution, the cover is freely located on the shafts and is made with the possibility of free movement in the vertical direction along the shafts as guides. It is assumed that the lid must always be in its lower position, which is determined either by the position of the stationary stopper (or bead basket), or by the bowl. The disadvantage of the known solution is that, in practice, the cover is wedged on the shafts, due to which it does not fall, or drops later than the moment when it is necessary. Such a mill is used in paint and varnish production to grind paint components. This disadvantage leads to the ingress of an excessive amount of harmful volatile components into the air, which increases the harmfulness of production; and this disadvantage can cause personal injury when attempting to manually lower the cover.

USEFUL MODEL DISCLOSURE

The developers of this technical solution were faced with the task of increasing the safety of using the bead mill.

The specified problem was solved by creating a bead mill, which includes

a working body, including a submersible bead basket, made with the possibility of placing in a bowl;

stirrers of the bead mill, made with the possibility of placing in the bowl;

a lid capable of closing the bowl;

fixed head of the bead mill;

wherein

the bead basket is located on the vertical shaft of the bead basket with the ability to move in the vertical direction;

the agitators are located on the vertical shafts of the agitators with the ability to move in the vertical direction;

the stirrer shaft and the bead basket shaft are connected to the head of the bead mill;

the lid contains holes corresponding in position and shape to the shafts of the stirrers and the shaft of the bead basket, the lid being movable in the vertical direction along the shafts;

characterized in that

the bead mill contains at least two linear actuators connected to the cover and the head of the bead mill;

and a control unit configured to direct control signals to linear actuators;

the linear drives are made with the possibility of independent movement of the cover in a given direction along the vertical axis under the control of signals from the control unit.

The technical result achieved by this technical solution is to improve the safety of the bead mill for personnel.

The technical result in the disclosed technical solution is achieved due to the fact that the lifting and lowering of the cover becomes controllable, while the installation of the cover on the rods of at least two actuators contributes to the even horizontal position of the cover in any position, which reduces the likelihood of its jamming. As a result, it is possible to timely close the lid, which minimizes the release of volatile components of the mixture into the surrounding space, and also reduces the likelihood of injury to personnel when trying to manually move the lid or involuntarily closing the lid.

BRIEF DESCRIPTION OF DRAWINGS

Fig. 1 is a schematic view of a bead mill.

IMPLEMENTING A UTILITY MODEL

In accordance with the disclosed technical solution, the bead mill includes a working body that includes a submerged bead basket 1 configured to be placed in a bowl 2. The possibility of placing in a bowl 2 can be provided due to the shape and dimensions of the basket 1, suitable for placement in a volume bowl 2, and also due to the location of the head part 3 of the bead mill relative to the frame 4 of the bead mill. So, the head part 3 of the bead mill can be located L-shaped with respect to the frame 4 of the mill. The head part 3 is stationary relative to the frame 4.

In the embodiment shown in Fig. 1, the bed 4 is made vertically on the base, and the head part 3 is connected to the upper part of the bed 4 and is located horizontally.

The mill may also contain a bowl clamping mechanism 5 connected to the mill frame and configured to fix the bowl in a predetermined position relative to the frame 4 under the basket 2.

The mill also contains agitators 6, made with the possibility of placing in a bowl 2.

The mill also contains a lid 7 adapted to close the bowl 2. The lid 7 is made of such a shape and size to be able to close the bowl 2 from above to prevent the volatile components of the mixture from escaping into the surrounding space.

In accordance with this useful model, the bead basket 1 is located on the vertical shaft 8 of the bead basket, and the mixers 6 are located on the vertical shafts 9 of the mixers with the ability to move in the vertical direction. In the diagram shown in Fig. 1, parts of the shafts above the cover 7 are covered with corrugated casings. The shafts 9 of the agitators 6 and the shaft 8 of the bead basket are connected to the head part 3 of the bead mill.

The cover 7 in accordance with the present technical solution contains holes corresponding in position and shape to the shafts 9 of the mixers and the shaft 8 of the bead basket 1, while the cover 7 is made with the possibility of moving in the vertical direction along the shafts. That is, the shafts act as a guide for free movement of the cover 7 along them.

In accordance with the present technical solution, the bead mill contains at least two linear actuators 11 connected to the cover 7 and the head part 3 of the bead mill. Also, the bead mill contains a control unit 13 configured to send control signals to linear actuators. In this case, the linear actuators 11 are made with the possibility of independent movement of the cover 7 in a predetermined direction along the vertical axis under the control of the signals of the control unit 13. The connection of the linear actuators 10 and 11 can be made by means of any known connecting element located on the actuator rods. In the embodiment shown in the drawing, the rods of the linear actuators are connected to the cover, and the bodies of the actuators are connected to the head part 3 of the bead mill.

By the term "independently" it should be understood that the movement of the cover 7 along the shafts 8 and 9 is essentially independent of the movement of the bead basket 1 or the mixers 9 and is carried out only as a result of the movement imparted by the linear drives 10 and 11 under the control of the control unit 13. It should be understood that in its upper position, the bead basket 1 prevents the cover 7 from moving below the position of the bead basket 1.

In a preferred embodiment, the actuators 10 and 11 are in the form of controlled pneumatic actuators (pistons). Such a design is the most explosion-proof and fire-safe and the least difficult to implement. In other embodiments, hydraulic or electrical actuators can also be used as linear actuators. It should be understood, however, that electric linear actuators must be explosion-proof.

The control unit in a preferred embodiment contains an interface for interaction with the mill operator, which is configured to receive from the user a command to move the cover 7 upward or a command to move the cover 7 downward. When an appropriate command is received, the linear drives 10 and 11 synchronously move the cover 7 in a predetermined direction along the shafts. Such an interface can be made in the form of a remote control with buttons, in the form of a touch panel, or in any other form.

The present technical solution has been described in detail with reference to certain variants of its implementation, however, it is obvious that it can be implemented in various versions without going beyond the scope of the claimed scope of legal protection determined by the claims of the utility model.
