Description

The invention relates to equipment for pressing powder products, namely for laying tablets after pressing into a boat for subsequent sintering, and can find application in powder metallurgy, chemical and other industries, in particular, can be used in enterprises for the manufacture of tablet fuel from uranium dioxide (UO ₂ ) for fuel elements (fuel elements) of nuclear reactors.

The prior art device for stacking pressed tablets containing a grip for removing tablets, a receiving device for tablets and a cartridge made with the possibility of lowering at the time of unloading the tablets inside the container (RU 2296053 C2, 03/27/2007). However, this device does not contain structural elements that provide sintering of the tablets after pressing.

Closest to the proposed solution is the installation for the production of pelletized fuel for fuel elements disclosed in RU 2158030 C2, 10.20.2000. The installation comprises a device for laying pressed tablets in a boat for subsequent sintering, the tablet sintering unit is equipped with a mobile boat storage box with tablets with a docking unit with a tunnel furnace, with a vehicle for moving the boat with tablets inside the storage box and a mobile unloading box with a docking station node with a mobile storage box.

The disadvantages of this device are the lack of compact packing of pressed tablets in a boat and the low accuracy and performance of the device.

The objective of the technical solution is to create a high-performance, re-adjustable device with a simple design for the continuous laying of pressed tablets made by dry and wet technology in a boat.

The technical result of the claimed solution is:

- the possibility of tightly stacking pressed tablets in the form of pre-assembled pillars in a sintering boat;

- the universal ability of the device to work under various tablet pressing technologies, both “dry” and “wet”;

- continuity and accuracy of the laying process;

- the possibility of readjustment to another type of tablet.

The specified technical result is achieved by the fact that the device for laying pressed tablets in a sintering boat contains a means for supplying tablets, and in addition, it is equipped with a tablet tipper, pill pill cutter, pillar drive, a device for pushing the pill pill onto said drive with the possibility of forming a layer accumulator of pillars, vacuum gripper for suctioning the formed layer, while the vacuum gripper is connected to the manipulator to move and after hydrochloric placing tablets in the boat. In this case, the vacuum pickup preferably has the ability to rotate 90 degrees.

In addition, the manipulator includes a horizontal pneumatic actuator and a vertical displacement servo.

In this case, the means for supplying tablets is made in the form of a conveyor belt.

The proposed device is illustrated by drawings. Figure 1 (a, b) shows the proposed device: a - front view, b - top view.

Figure 2 - manipulator with a vacuum grip for a layer of pillars of tablets.

Figure 3 - node formation and storage columns in an enlarged scale.

The claimed device contains (Fig. 2) a conveyor belt 1 for removing and moving the tablets after pressing, a unit for forming a layer of tablets, which includes: a tipper 11 (Fig. 1a), designed for tipping vertically moving tablets, a cutter 2 pillar of tablets, a corrector 15 columns of tablets and a device 3 for pushing the formed column of tablets from the conveyor 1. To accumulate the collected pill pill, the device is equipped with a drive 4 and two correctors 5 pill pill placed on drive 4.

In addition, the device comprises a vacuum gripper 6 for suctioning a layer formed from pillars of pillars formed on the drive 4 and a manipulator 7 (Fig. 3) for moving the specified layer into a boat connected to the gripper 6. The manipulator 7 is equipped with a pneumatic horizontal displacement 12 and a vertical displacement servo 13 The vacuum capture 6 has the ability to rotate 90 ° in the horizontal plane with the help of a rotary pneumatic cylinder 14. The vacuum capture 6 is connected to the vortex pump and the gate (not shown) to create and remove the discharge ezheniya in its air system.

The device also contains a roller table 8 for placing boats and mechanisms for fixing 9 and pushing 10 boats from the roller table 8.

The device operates as follows.

The tablets after pressing, which are short cylinders, are overturned from the end onto the generators by the tipper 11, are moved along the conveyor belt 1 and are formed using the corrector 15 into a column of the required length. The formed column of tablets with the help of the cutter 2 is separated from the main stream and the device 3 (pusher) is moved parallel to the conveyor belt 1 to the drive 4 pillars of tablets with column correction using corrections 5. The process of accumulation of pillars of tablets on the drive 4 is carried out sequentially in a step-by-step mode until a layer is formed from a given number of posts. A vacuum grip 6 is lowered onto the formed layer, which sucks the tablets to its base. Using the manipulator 7, a layer of tablets is transferred to a boat mounted on the roller table 8. In the same way, the layers are laid into the boat, as required by the technological process, rotated by 90 degrees using the rotary pneumatic cylinder 14. The filled boat is fed from the roller table 8 into the boat using the collision mechanism 10 sintering transport corridor. Then, an empty boat is installed on the roller table 8, and the described cycle is repeated.

Thus, the claimed device allows for a continuous process of laying preformed sets of pressed tablets, limited by the height of the columns and their number, in sintering boats with high accuracy and performance.
