The utility model feed bin Pneumatic butterfly valve places under the bin outlet gate valve and prepares directly over the batch can, under the preparation batch can batch can Pneumatic butterfly valve is installed, so that the transmission of powder can only depend on gravity to finish between feed bin and the preparation batch can, convenient and saving equipment and transmission cost.
In the utility model preparation batch can the batch can sensor is installed, the transfer pot sensor is installed in the pneumatic transporting tank sending, controller all is connected with batch can sensor, transfer pot sensor.
The utility model is simple for structure easy to use, and traffic capacity is larger, and fed distance is far away, and transport efficiency is high, and the delivery of maintenance cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the close phase positive-pressure pneumatic of the utility model embodiment continous way load transfer device comprises dust exhaustor 1, feed bin 2, bin outlet gate valve 3, feed bin Pneumatic butterfly valve 4, preparation batch can 5, batch can Pneumatic butterfly valve 6, blow off valve 7, pneumatic transporting tank sending 8, delivery duct 9, atmospheric valve 10, batch can sensor, transfer pot sensor and controller.Dust exhaustor 1 is installed on the feed bin 2, and feed bin 2 outlets are equipped with-bin outlet gate valve 3, and bin outlet gate valve 3 is connected with feed bin Pneumatic butterfly valve 4, and feed bin Pneumatic butterfly valve 4 is installed on the preparation batch can 5; Between preparation batch can 5 and the pneumatic transporting tank sending 8 blow off valve 7 is installed, between feed bin 2 and the preparation batch can 5 atmospheric valve 10 is installed, in the preparation batch can 5 the batch can sensor is installed, the batch can sensor is used for detecting preparation batch can 5 interior powder filling amounts, the transfer pot sensor is installed in the pneumatic transporting tank sending 8, the transfer pot sensor is used for detecting pneumatic transporting tank sending 8 interior powder filling amounts, controller and feed bin Pneumatic butterfly valve 4, batch can Pneumatic butterfly valve 6, blow off valve 7, pneumatic transporting tank sending 8, atmospheric valve 10, the batch can sensor, the transfer pot sensor all connects, controller, the batch can sensor, the transfer pot sensor all can adopt existing techniques in realizing; 5 outlets of preparation batch can are equipped with batch can Pneumatic butterfly valve 6 and are connected with pneumatic transporting tank sending 8; Pneumatic transporting tank sending 8 is connected on the delivery duct 9, powder material can be delivered to named place of destination.
Working process is as follows:
At first be feed bin 2 chargings, 2 li of feed bins have after the material, bin outlet gate valve 3 is placed normally open, open feed bin Pneumatic butterfly valve 4 and batch can Pneumatic butterfly valve 6, open simultaneously atmospheric valve 10, powder material is then because Action of Gravity Field enters pneumatic transporting tank sending 8 by preparation batch can 5, after pneumatic transporting tank sending 8 interior material are full, close simultaneously batch can Pneumatic butterfly valve 6 and blow off valve 7, pneumatic transporting tank sending 8 is carried and is started afterwards.
In the process that pneumatic transporting tank sending 8 is being carried, then powder material continues to pack into preparation batch can 5 until material full (namely reaching the full settings of preparation batch can powder) is then closed feed bin Pneumatic butterfly valve 4 and atmospheric valve 10.
