PL67995Y1 - Sliding and infeed mechanism for freezing plates in the plate freezer - Google Patents

Description

Pattern description

The object of the utility model is the mechanism of extending and feeding of freezing plates in a vertical plate freezer. Food of animal origin is frozen in rectangular or square blocks.

Known are vertical plate freezers where the displacement and advancement of the freezing plates with frozen blocks takes place with the use of hydraulic devices of large dimensions. Known solutions are disclosed in AU 543304 and WO 2011009461.

The disadvantage of the known devices is the use of additional sets of hydraulic aggregates - pump stations.

These inconveniences have been eliminated by building a device that has its own independent drive.

The essence of the utility model is the mechanism of extending and feeding of freezing plates with frozen food blocks in a vertical plate freezer. The freezing plate is fixed on the retaining beam by means of a plastic retaining shoe. The retainer beam connects the left track and the right track of the main frame. In the left and right guides, there are lifting brackets connected by a lifting beam, on which bent ejectors are fastened with hooks.

The freezing plates, fixed on the beam, are connected in pairs and fastened on sliding pins. In the side part of the main frame, on the stiffening beam, there is a bracket to which a screw jack with a movable self-propelled screw is attached. The hoist travel bolt is connected to a connecting hub located in the mechanism housing. The mechanism housing is connected by a ring to the first freezing plate.

The amount of displacement is determined by the travel limiter. The movement of extending the freezing plates automatically causes the ejectors bent with frozen blocks to move.

The sliding starts when defrosting is complete.

After removing the frozen blocks and lowering the bent ejectors, the freezing plates are moved back in the reverse order. After they are completely slipped, the device is ready for the next technological operation.

The advantage of the utility model is its compact structure, equipped with its own independent drive unit.

The solution according to the utility model is shown in the drawing where:

Fig. 1.- shows a front view of the device with a partial cross-section of the spreading mechanism,

Fig. 2.- shows a side view and a cross-section through the ejector bent with the freezing plate,

Fig. 3.- shows the side view showing the spreading drive,

Fig. 4.- shows a cross-section of the spreading and feeding mechanism showing the freezing plates,

Fig. 5.- shows the connection of the freezing plates with pins. The freezing plate H is fixed on the retaining beam 1 by means of plastic shims 8. The retaining beam 7 connects the left guide 1. to the right guide 2 of the main frame. In the left 1 and right 2 guide there are lifting brackets, left 4 and right 5 connected by a lifting beam 3, on which, by means of catches 9, bent ejectors 1_2 with plastic caps in the vertical part 13 and the horizontal part 14 are mounted. the fixing beam 7 of the freezing plates H is fed through the conduit 16, pressurized freezing agent, and discharged after relieving and reducing the pressure through the conduit 15. The freezing plates H are connected in pairs and the shift is fixed by bolts 27 and 28 by the value x. In the side part of the main frame, between the upper 17 and lower 18 stiffening beams there is a bracket 10, to which a screw jack with a movable screw 25 is attached with its own drive 19. The lifting screw 26 is connected to the connecting hub 30, located in the housing of the spreading and feeding mechanism 29, of the freezing plates H. The extension x is set by the sliding limiter 31 The movable screw 25 is protected by the cover 33. The sliding movement of the freezing plates 11 automatically causes movement of the bent ejectors 12. After the operation of removing the frozen blocks and lowering the bent ejectors 12 into the lower position, the freezing plates H are moved back to their initial position and the device is ready for the next technological operation.
