Description

The utility model is intended for use in the chemical industry, powder metallurgy, in particular for the formation of fuel pellets from carbon-containing and other fine materials.

A fully automatic closed granulation system is known, containing a wet mixing granulator, a guide rack mounted on a fixed frame, as well as supporting and adjacent blocks, a guide (CN patent No. 103157403, B01J 2/00, 03/29/2013).

A disadvantage of the known granulation system is the lack of the possibility of carrying out complex maintenance, as well as equipment repair by a robotic technological complex.

The known design implies the presence of operating personnel to perform equipment maintenance operations.

The technical task of the claimed utility model is to create a design of a granulator used as part of a robotic line for the preparation of press powder.

The technical result of the claimed utility model is the production of granules from toxic materials in the absence of working personnel in the working area.

The technical result is achieved due to the fact that the press powder granulator for a robotic line (hereinafter referred to as the granulator) contains a fixed welded frame on which the granulation mechanism is fixed. The granulator is equipped with a container for powder fixed on a fixed welded frame with a unit for dust-free transfer of unloading connected to a unit for horizontal screw feeding and a unit for vertical screw feeding of powder into the granulation mechanism, a container for the obtained granules, a unit for dust-free transfer of loading docked to it and technological panels with quick-release pneumatic and electrical connections for supplying process media and power supply via a multi-connector. The granulation mechanism is located in a welded housing, which contains a sealed cover with a handle for gripping the manipulator during maintenance. Technological panels are displayed on one side to reduce the space for maintenance and repair operations. Quick disconnect pneumatic and electrical connections are made unified for use with different types of manipulators.

The proposed technical solution is illustrated by the following drawings: Fig. 1 shows a general view of the press powder granulator, Fig. 2 is a top view showing the areas of movement of the robotic technological complex.

The press powder granulator for the robotic line includes a horizontal screw feed unit 1, consisting of a horizontal socket with inclined inlet and outlet nozzles. Node 1 provides a dosed supply of powder to the hopper 2 with a level sensor 3.

The unit 1 is connected to the unit 4 of the dust-free transfer of the discharge, which transfers the powder from the powder container 5 to the unit 1 of the horizontal screw feed.

The node 6 of the vertical screw feed includes an angle gearbox, a servomotor and a screw, which prepresses the powder and feeds it to the granulation mechanism 7.

The granulation mechanism 7 is located in a welded housing 8, closed with a sealed lid, which is secured with hinged bolts. The cover has a handle for gripping the manipulator during maintenance.

The node 9 of the dust-free transfer of loading is similar in design to the node 4 of the dust-free transfer of unloading and is designed to load the finished product into the container for the obtained granules 10.

The nodes of the granulator are fixed on a fixed welded frame 11, which ensures the rigidity of the structure. On the frame 11 from the side of the zone of movement of the manipulator serving the equipment, there are technological panels 12 with pneumatic and electric quick-release connections, the shape of which is made under the arm of the manipulator. Since the technological panels 12 are displayed on one side, this design allows to reduce the space for maintenance and repair operations.

The manipulator as part of the robotic technological complex replaces the powder container 5 and the container for the obtained granules 10, which are automatically fed into the working position. Also, with the help of the manipulator, if necessary, the frame 11 is removed from its place and placed in the same position.

On the panels 12 for supplying media, for supplying electrical cables, quick-release connections are unified, that is, they can be used with different types of manipulators. At the same time, taking into account the unification, the holders are equipped with various standard sizes for various technological tasks and the capabilities of manipulators.

The proposed design of the granulator allows the robotic technological complex to provide comprehensive maintenance of parts of the plant with the possibility of automated changeover and equipment repair.

The inventive press powder granulator for a robotic line operates as follows.

Before starting work, technological media are supplied and power is connected to the granulator by means of technological panels 12 through a multi-connector (not shown in the figure) located on a universal platform using quick-connect pneumatic and electrical connections.

An atmosphere with the required technological parameters is created in the granulator. The gas enters the unit 9 of the dust-free transfer of loading the container for the obtained granules 10. The gas exits from the unit 4 of the dust-free transfer of the unloading of the container for the powder 5.

The original filled powder container 5 is installed on the neck of the dust-free unloading unit 4 using a manipulator. Similarly, an empty container for the obtained granules 10 is docked to the neck of the node 9 dust-free pouring download. Before installation, the manipulator removes protective covers from the container for powder 5 and the container for obtained granules 10 (not shown in the figure).

The powder is poured from the powder container 5 through the dust-free unloading unit 4 into the socket of the horizontal screw feed unit 1, then the screw moves the powder into the hopper 2. The filling of the hopper 2 is controlled by the level sensor 3.

The auger unit 6 of the vertical screw feed provides metered feed with pre-pressing of the powder from the hopper 2 onto the rolls of the granulation mechanism 7. The pressing force is controlled by strain gauges (not shown in the figure), the adjustment of which is periodically performed using a control weight installed using a manipulator. The speed of the augers of units 1 and 6 is controlled automatically.

The obtained granules from the granulation mechanism 7 enter the container for the obtained granules 10 through the node 9 of the dust-free transfer of the load.

When undocking the powder container 5 and the container for the obtained granules 10 from the dust-free transfer units 4 and 9, respectively, the mating surfaces are wiped from traces of product particles by means of a manipulator.

The granulator, if necessary, is transported to the place of repair or disposal together with the frame 11. For transporting, lifting and lowering the granulator, a special mark is placed on the frame 11 for precise integration of the granulator into the robotic line.

The manipulator can also carry out the following operations: removing the fasteners from the foundation, detaching the granulator blocks and repeating the operations in reverse order. Another manipulator lifts the granulator for removal from the operating room and then performs the reverse operations to place the granulator exactly into place in the production line.

The design of the granulator for the robotic technological complex provides for the absence of manual operations to remove equipment from the robotic line. This eliminates the errors of the operating personnel, since all the functions for servicing by means of a robotic technological complex are programmed in the control system. As a result, it becomes possible to carry out the operations of changing equipment and carrying out short repairs more accurately and accurately.

Thus, the use of the claimed press powder granulator for a robotic line makes it possible to produce granules from toxic materials in the absence of personnel in the working area.
