Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises two material pots 2 be connected on threeway conveying pipeline 1 discharging opening.Material pot 2 comprises tank body 25, and tank body 25 upper end connects unidirectional feed pipe 8 by upper flange 9, and tank body 25 lower end connects discharge nozzle 14 by lower flange 13.Described tank body 25 side connects air inlet and exhaust valve 11 by intake and exhaust valve seat 10, is mainly used in the exhaust of pressurized air air inlet and residual air.Described tank body 25 side is provided with level-sensing device 23 and pressure relay 24, and level-sensing device 23 is for detecting the height of materials in tank body 25, and pressure relay 24 is for detecting the pressure condition in tank body 25.
Cylinder 5 is fixed in unidirectional feed pipe 8 upper end, and the piston rod of cylinder 5 drives upper conical spool 7 up-and-down movement of lower end by pipe link 6, thus it is reinforced in tank body 25 to open or close unidirectional feed pipe 8.Described unidirectional feed pipe 8 side connects telescopic pipe 3 by feed opening flange 4, and feed opening flange 4 is provided with Pneumatic butterfly valve 22.
Be provided with the first seal ring 26, first seal ring 26 between described unidirectional feed pipe 8 and upper conical spool 7 to be close on unidirectional feed pipe 8 madial wall.
Discharge nozzle 14 internal fixtion lower spring cup 21, lower spring cup 21 is installed rubber air spring 19, rubber air spring 19 upper end connects upper spring seat 17, upper spring seat 17 upper end connects inferior pyramidal valve 12, rubber air spring 19 can drive inferior pyramidal valve 12 up-and-down movement, reaches the object of opening or closing tank body 25.Described discharge nozzle 14 side connects discharging flange 15, by discharging flange 15 discharging.Described lower spring cup 21 lower end is provided with gas port 16.
Described discharge nozzle 14 side is provided with access door 20, can be overhauled the rubber air spring 19 of discharge nozzle 14 inside by access door 20.
Be provided with the second seal ring 27, second seal ring 27 between described lower flange 13 and inferior pyramidal valve 12 to be close on lower flange 13 madial wall.
Described tank body 25 sidewall connects multiple supporting leg 18, supports tank body 25 by supporting leg 18.
Principle of work of the present invention is: during work, and level-sensing device 23 detects material in material pot 2, and cylinder 5 controls upper conical spool 7 and opens, and material is entered in two material pots 2 by threeway conveying pipeline 1.Along with material increases, the air in tank body 25 is discharged by air inlet and exhaust valve 11.When material reaches level-sensing device 23 detection height, Pneumatic butterfly valve 22 and upper conical valve 7 are closed, and air inlet and exhaust valve 11 is converted to air-suction state, and inferior pyramidal valve 12 is opened subsequently, and material is carried to feed point under compressed-air actuated effect.
Pressurized air enters tank body 25 from air inlet and exhaust valve 11.According to the transporting resistance of material, pressurized air reaches required pressure in tank body 25.Under the effect of constant air pressure, the material in tank body 25 is transported to emptying point through delivery duct.
When material in tank body 25 reduces, when level-sensing device 23 is got back to without material state, air inlet and exhaust valve 11 is closed, and utilizes the residual air in tank body 25 to continue to send clout.When pressure reduces, during pressure relay 24 decompression, air inlet and exhaust valve 11 is converted to exhaust condition, residual air in tank body 25 is discharged through air inlet and exhaust valve 11, through time delay, Pneumatic butterfly valve 22 and upper conical valve 7 are opened heavily again, and gas port 16 is ventilated, inferior pyramidal valve 7 is pushed up virgin state, and process of transmitting enters next new circulation.
In order to prevent, because level-sensing device 23 and the malfunctioning tank body 25 that causes of pressure relay 24 cannot work, generally should setting up time controling in automatically controlled program to replace level-sensing device 23 and pressure relay 24 to complete corresponding action.
Signal to tank body 25 when material reaches the detection height of high charge level meter in the feed bin in emptying point and stop conveying; Otherwise, signal to tank body 25 when material drops to the detection height of low level-sensing device in the feed bin in emptying point and carry.
