The specific embodiment
Embodiment during following the utility model is incited somebody to action by reference to the accompanying drawings is further described:
Shown in Fig. 1 ~ 2, the utility model mainly comprises two material pots 2 that are connected on threeway conveying pipeline 1 discharging opening.Material pot 2 comprises tank body 25, and tank body 25 upper ends connect unidirectional feed pipe 8 by upper flange 9, and tank body 25 lower ends connect discharge nozzle 14 by lower flange 13.Described tank body 25 sides connect air inlet and exhaust valve 11 by intake and exhaust valve seat 10, are mainly used in the exhaust of pressurized air air inlet and residual air.Described tank body 25 sides are provided with level-sensing device 23 and pressure relay 24, and level-sensing device 23 is for detection of the height of materials in the tank body 25, and pressure relay 24 is for detection of the pressure condition in the tank body 25.
Being provided with first seal ring, 26, the first seal rings 26 between described unidirectional feed pipe 8 and the upper conical spool 7 is close on unidirectional feed pipe 8 madial walls.
Discharge nozzle 14 interior fixedly lower spring cups 21, rubber air spring 19 is installed on the lower spring cup 21, rubber air spring 19 upper ends connect upper spring seat 17, upper spring seat 17 upper ends connect inferior pyramidal valve 12, rubber air spring 19 can drive inferior pyramidal valve 12 up-and-down movements, reaches the purpose of opening or closing tank body 25.Described discharge nozzle 14 sides connect discharging flange 15, by 15 dischargings of discharging flange.Described lower spring cup 21 lower ends are provided with gas port 16.
Described discharge nozzle 14 sides are provided with access door 20, can overhaul the rubber air spring 19 of discharge nozzle 14 inside by access door 20.
Being provided with second seal ring, 27, the second seal rings 27 between described lower flange 13 and the inferior pyramidal valve 12 is close on lower flange 13 madial walls.
Connect a plurality of supporting legs 18 on described tank body 25 sidewalls, support tank body 25 by supporting leg 18.
Principle of work of the present utility model is: during work, level-sensing device 23 detects material in the material pot 2, and the upper conical spool 7 of cylinder 5 controls is opened, and material enters in two material pots 2 by threeway conveying pipeline 1.Along with material increases, the air in the tank body 25 is discharged by air inlet and exhaust valve 11.When material reached level-sensing device 23 detection height, Pneumatic butterfly valve 22 and upper conical valve 7 were closed, and air inlet and exhaust valve 11 is converted to the air inlet 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 the tank body 25 is transported to the emptying point through delivery duct.
Material reduces in tank body 25, and when level-sensing device 23 was got back to no material state, air inlet and exhaust valve 11 was closed, and utilizes the residual air in the tank body 25 to continue the transmission clout.When pressure reduces, during pressure relay 24 decompressions, air inlet and exhaust valve 11 is converted to exhaust condition, residual air in the 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, gas port 16 ventilations, to virgin state, process of transmitting enters next new circulation with inferior pyramidal valve 7 tops.
In order to prevent to work because of level-sensing device 23 and the pressure relay 24 malfunctioning tank bodies 25 that cause, generally should control to replace level-sensing device 23 and pressure relay 24 to finish corresponding action in the automatically controlled program time of setting up.
Signaling to tank body 25 when material in the feed bin in emptying point reaches the detection height of high charge level meter stops to carry; Otherwise, when material in the feed bin in emptying point drops to the detection height of low level-sensing device, signal to tank body 25 and carry.
