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 tank body 1, and tank body 1 upper end connects intermediate feed pipes 8 by upper flange 24, and intermediate feed pipe 8 upper ends are flexible coupling by rubber and 7 connect Hand-operated butterfly valves 6.Fixed air jar support 12 on described intermediate feed pipe 8 lateral walls, fixing cylinder 14 on the cylinder support 12, the piston rod front end of cylinder 14 connects cylinder joint 16.Cylinder joint 16 connects by connecting shaft 19 and connects rotating shaft 18 on second swing arm, 15, the second swing arms 15, connects first swing arm 13 in the rotating shaft 18.Described first swing arm, 13 front ends connect fork 21 by pivot shaft 17, connect fork 21 lower ends and connect taper inlet valve 22.Described cylinder 14 drives taper inlet valve 22 up-and-down movements by first swing arm 13, second swing arm 15.Be provided with seal ring 23 between described upper flange 24 and the taper inlet valve 22, seal ring 23 is connected on upper flange 24 madial walls, prevents gas leakage.
Described tank body 1 is provided with intake and exhaust valve seat 2, connects air inlet and exhaust valve 3 on the intake and exhaust valve seat 2.Intake and exhaust valve seat 2 is provided with a plurality of pores, reaches the purpose of giving vent to anger evenly, reducing wear by a plurality of pores.
Described tank body 1 is provided with level-sensing device 9, following level-sensing device 10 and pressure relay 11,
Described tank body 1 lower end connects a plurality of supporting legs 5, is used for supporting whole tank body 1.
Described tank body 1 lower end is provided with discharging opening 4.
Described tank body 1 sidewall is provided with access door 20, and when access door 20 blocked up sand at material, it is convenient that sand is dredged in cleaning.
When the upper and lower level- sensing device 9,10 in the tank body 1 was in no material state and air inlet and exhaust valve 3 and places exhaust condition, taper inlet valve 22 was opened, and material enters tank body 1.Along with material increases, the air in the tank body 1 is discharged by air inlet and exhaust valve 3.When level-sensing device 9 detection height were gone up in material arrival, taper inlet valve 22 cut out through delaying time 2 ~ 3 seconds, and air inlet and exhaust valve 3 is converted to the air inlet state, opens subsequently.
Pressurized air enters tank body 1 from air inlet and exhaust valve 3.According to the transporting resistance of material, pressurized air reaches required pressure in tank body 1.Under the effect of constant air pressure, the material in the tank body 1 is transported to discharging opening 4 through delivery duct.Last level-sensing device 9 is at first got back to free state.
Material reduces in tank body 1, and when following level-sensing device 10 was got back to no material state, air inlet and exhaust valve 3 was closed, and utilizes the residual air in the tank body 1 to continue the transmission clout.When the pressure reduction, during pressure relay 11 decompressions, air inlet and exhaust valve 3 is converted to exhaust condition, and the residual air in the tank body 1 is discharged through air inlet and exhaust valve 3, and through time-delay, taper inlet valve 122 is opened heavily again, and process of transmitting enters next new circulation.
For prevent because of upper and lower level- sensing device 9,10 and the pressure relay 11 malfunctioning tank bodies 1 that cause can't work, generally should control the time of setting up to replace in the automatically controlled program upper and lower level- sensing device meter 9,10 and pressure relay 11 finish corresponding action.
