Description

The utility model relates to technical devices for crushing glass products, reducing the energy consumption for grinding it on the corresponding main crushing means (machines).

Rotor, hammer and other crushers are known from the prior art, having an inlet feed hopper for crushed materials, a rotor with hammers mounted on it for crushing and an unloading window for crushed material (Zimin A.I., Gorelov Yu.V. Increasing the efficiency of crushing equipment in construction industry.-Yekaterinburg: UrGUPS, 2007, p. 173).

The disadvantages of the known technical solutions include their high energy intensity, due to the lack of options for using types of energy, alternative to electrical energy.

The closest to the claimed technical solution - the prototype - is a device for crushing glass products containing sequentially installed inclined belt conveyor for supplying glass containers to the crushing zone, designed to break the glass containers into fragments, a vertical column with crushing elements located on its inner surface, a means for crushing fragments and a means for receiving glass chips (RF Patent No. 134078 U1, publ. 10.11.2013).

The advantages of the prototype include a relatively low energy consumption of crushing, due to the inclusion of an additional stage of crushing, based on the use of the kinetic energy of the falling glass containers, before the main stage, which ultimately leads to the use of the main crushing equipment with lower energy consumption.

The disadvantages of the prototype should nevertheless include still high energy costs due to the low efficiency of use of the kinetic energy of the falling glass containers, due to that. that randomly oriented glass containers do not break when dropped. a large percentage of unbroken “bottoms” and “necks”.

The objective of the utility model is to ensure the optimal, from the point of view of crushing efficiency, orientation of the falling glass containers.

The technical result is a reduction in energy consumption.

The problem is solved, and the claimed technical result is achieved by the fact that the device for crushing glass containers containing sequentially installed an inclined belt conveyor for supplying glass containers to the crushing zone, designed to break the glass containers into fragments, a vertical column with crushing elements located on its inner surface, a means for crushing fragments and means for receiving glass chips, equipped with a means of horizontal orientation of the glass containers at the entrance to the column, while the means horiz For the actual orientation of the glass containers, it is advisable to perform in the form of horizontal stops placed on the conveyor belt and / or in the form of two spring-loaded shutters pivotally mounted on opposite walls in the upper part of the column, forming a receiving hopper with pitched surfaces inside the column and an opening line normal to the direction of conveyor movement .

The utility model is illustrated by images, where:

- in FIG. 1 shows a device for crushing glass containers, side view;

- in FIG. 2 is a view A in FIG. one.

A device for crushing glass containers 1 includes the following structural elements: inclined conveyor 2 for supplying glass containers 1 to the column 4, horizontal stops 3 to ensure horizontal orientation of the glass containers 1, spring-loaded flaps 5 to ensure horizontal orientation of the glass containers 1, inclined shelves 6 with evenly distributed on their surface pointed elements 7 for crushing horizontally oriented glass containers 1, and the main crushing means (machine) 8, including a loading hopper 9, shock drums trays 10, unloading window 11 of commodity glass chips 12.

A device for crushing glass works as follows. Glass containers 1 after preliminary (sorting, washing, etc.) operations are fed to an inclined conveyor 2, equipped with horizontal stops 3, through which, as well as due to the movement of the conveyor 2 and its angle of inclination, the horizontal orientation of the glass container 1 is ensured. Then, under the action the pressure forces of the accumulated horizontally oriented glass containers 1, or by triggering the sensor in the case of automation, a horizontally oriented glass container 1 is fed to the top of the column 4 equipped with horizontal orientation of the glass containers in the form of two spring-loaded shutters hinged on opposite walls 5. When enough glass containers 1 accumulate in the storage hopper formed by the shutters 5, under the action of the gravity of the accumulated horizontally oriented glass containers 1 or upon triggering the sensor in case of automation, the shutters 5 are opened, and horizontally oriented glass containers 1 fall towards the inclined shelves 6 with pointed elements evenly distributed on their surface 7. As a result of the impact of a horizontally oriented glass container 1 against the pointed elements 7, glass fragments are formed that fall into the working chamber of the main crushing means (machine) 8 through its loading hopper 9, where they are crushed by impact hammers 10 more efficiently with less energy. Next, through the discharge window 11 from the main crushing means 8 is displayed commodity glass chips 12.

Glass containers supplied for crushing in order to further use the resulting glass chips for the production of glass containers, building materials, etc., are represented by two main types:

- banks;

- bottles.

From the point of view of “breakability”, the most difficult raw materials are bottles (determined experimentally), which were used to determine the optimal orientation of glass containers in the light of the problem being solved by a useful model.

The experiments on determining the nature of fragments at various heights depending on the position of the bottle showed that the most optimal position of the bottle when feeding it into the neck of the column is horizontal, because This position is characterized by:

- the minimum number of large fragments (most of the fragments are small);

- almost guaranteed destruction of the bottom and neck of the bottle.

Oriented in this way by means of the claimed device for crushing glass containers, experiments have shown that it reduces the energy consumption for grinding it into standard chips by 5-7% compared with the prototype.

The foregoing allows us to conclude that the task set - ensuring the optimal, from the point of view of crushing efficiency, orientation of the falling glass containers - is solved, and the technical result - reduction of energy consumption - is achieved.

The analysis of the claimed technical solution for compliance with the conditions of patentability showed that the characteristics indicated in the independent claim are interrelated with each other with the formation of a stable set of necessary attributes unknown at the priority date from the prior art sufficient to obtain the desired technical result.

The properties regulated in the claimed device by individual features are well known in the art and require no further explanation.

Thus, the above information indicates the fulfillment of the following set of conditions when using the claimed technical solution:

- an object embodying the claimed technical solution, when implemented, relates to technical devices for crushing glass products. reducing energy consumption for grinding it on the corresponding main crushing means;

- for the claimed object in the form described in the formula, the possibility of its implementation using the methods and methods described above or known from the prior art on the priority date is confirmed;

- the object embodying the claimed technical solution, when implemented, is able to ensure the achievement of the technical result perceived by the applicant.

Therefore, the claimed object meets the criteria of patentability "novelty" and "industrial applicability" under applicable law.
