Abstract

This invention relates to devices for remotely switching a stream during pneumatic conveying of material through pipes. The purpose of the invention is to increase productivity and reliability. The device allows to reduce the time and increase the reliability of the installation of a given flow direction (GSP) in the switch due to the system of automatic changing the direction of rotation of the rotational drive of the transfer pipe and the orientation associated with its adaptation, which in combination with the actuator 3 longitudinal movement of the locking tip located on the output the end of the transfer pipe with the possibility of contacting with the output pipes and with the limit switch included in the chain of the 1 turn actuator 1 of the nozzle allows the search for a predetermined flow direction remotely retracted locking tip. . The reliability of actuation is also ensured by the fact that the contacts of the start button 20 interlocked from the relay circuit 19 of the actuator of rotation of the transfer nipple 2 are included in the drive chain 3 for longitudinal movement. 4 Il. g (L

The statement relates to a PPHM device for remotely switching the flow direction when transporting material through pipes.

The purpose of the acquisition is to increase productivity and reliability.

FIG. I shows a block diagram of the device; in fig. 2 - switch in assembled form, cross section; in fig. 3 - section aa of FIG. 2; in fig. 4 is a circuit diagram of the device.

The device consists of an electric drive I rotate the transfer pipe 2 and is made in the form of an electromy pusher drive 3 longitudinal movement of the spring-loaded locking tip 4 and is equipped with an automatic search system 5 for a given flow direction, which includes the automatic rotation direction I drive system 6 and is associated with a device 7 oenationalization of the transfer pipe 2. The transfer pipe 2 is installed coaxially on the input pipe 8 with the possibility of interaction with one of the output n tubes 9 fixed to the housing

10, and the locking tip 4 is placed coaxially at the output end of the transfer pipe 2 with the possibility of interaction with the limit switch

11, also mounted on the nozzle 2 and included in the electrical circuit of the actuator 1. The orientation adaptation device 7 includes limit switches 12 installed in recesses on the inner surface of the housing 10 in the location area of the locking tip 4 for contact with a locking element 13 made in the form of a spring ball placed on the horizontal bar 14 fixed on the transfer nipple 2. The system 6 automatically changes the direction of rotation of the drive I and includes ends e switches of the right 15 and left 16 rotation, mounted on the stopper I7, which is mounted inside the housing 10 with the possibility of contact with the horizontal film 14. In addition, the drawing shows the device 18 of the actuator reverse I, included in system 6, and also included in the composition of the system 5 automatic search for a given direction

relay 19 of the opening of the drive circuit 1, interlocked contacts of the start button 20 of the device, switched on and the drive circuit 3 for moving the locking tip 4, and an electrical switch 21 for setting the required flow direction.

 

The device works as follows.

If it is necessary to feed the mixture through one of the outlet nozzles 9 by an electric switch 21, it closes the circuit. The limit switch 12 corresponding to this direction in the orientation adaptation tool 7 of the transfer pipe 2. After this, the actuator 3 switches on the actuator 3, system 5 and fixture 7, while the actuator 3 a hive, the locking tip 4 of the nozzle 9 in which it was located, in its final position, closes the contacts of the limit switch 11, which turns on the actuator 1. Rotation of the actuator I occurs until the fixed I3 does not protruct with limit switch 12, which interrupts circuit 5 of system 5, through circuit 19, disconnects drive circuit 1, stops its rotation, and relieves voltage from actuator 3, while locking lug 4 under the action of a spring fits tightly into the cone socket of a given outlet fitting 9. If prior to setting a given direction, horizontal bar 14 contacts with one of the limit switches 15 or 16, then the signal enters the device 18 of the reverse drive I, which This begins to rotate in the opposite direction until the exit and a predetermined direction. At the time of actuation, the device 18 is operable by the systems 5 and 6 and the device 7 is supported by an interlocked button 20 and turnip 19, the same also ensures that the entire device is de-energized.
