When the constant-speed high-level tank is used, the first electromagnetic valve or the second electromagnetic valve is controlled to fill or discharge gas into the air bag through pressure data obtained by the pressure sensor, so that the pressure at the discharge port is maintained at a set pressure, and the discharge port can discharge materials at a constant speed.
In the above technical scheme, preferably, the top plate and the bottom plate are arranged at two ends of the air bag, and a reset tension spring is arranged between the top plate and the bottom plate. Adopt this structure can be when needs gassing, directly open the second solenoid valve can, the automatic distance of dwindling between roof and the bottom plate of elasticity that the extension spring can reset, and exhaust gas is changeed the control.
In the above technical scheme, preferably, the inner side wall of the tank body is provided with a guide slide rail, the bottom plate is fixed at the bottom of the slide rail, and the top plate is slidably arranged on the slide rail. Adopt this structure to make the gasbag fixed in the internal position of jar, prevent that it from plugging up feed inlet or discharge gate.
Among the above-mentioned technical scheme, it is preferred, the jar body can be dismantled and set up on the support, the support includes a plurality of stands, be provided with the supporting part between the stand, be provided with the confession on the supporting part the passageway of discharge gate ejection of compact, the stand top is provided with the slide, it is provided with the piece of leaning on to slide on the slide, it is provided with the rack to lean on the piece bottom, slide one side be provided with rack complex gear, gear revolve so that lean on the piece and be close to or keep away from the jar body, the coaxial ratchet that is provided with of gear, be provided with on the stand with ratchet complex pawl. By adopting the structure, the tank body on the bracket can be replaced, and the installation of the tank bodies with different sizes can be met.
Compared with the prior art, the utility model, following beneficial effect has: when the constant-speed high-level tank is used, the first electromagnetic valve or the second electromagnetic valve is controlled to fill or discharge gas into the air bag through pressure data obtained by the pressure sensor, so that the pressure at the discharge port is maintained at a set pressure, and the discharge port can discharge materials at a constant speed.
Drawings

Fig. 2 is a schematic top view of the bracket according to the embodiment of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 2, a constant-speed high-level tank, including airtight jar body 1, be provided with feed inlet 11 and discharge gate 12 on jar body 1, it is provided with pressure sensor 2 to be close to discharge gate 12 side in jar body 1, be provided with gasbag 3 in jar body 1, gasbag 3 is connected with admission line 31 and pipeline 32 of giving vent to anger, be provided with first solenoid valve 4 on the admission line 31 and connect air pump 5, pipeline 32 of giving vent to anger stretches out jar body 1 and is connected with second solenoid valve 6, pressure sensor 2, first solenoid valve 4 and second solenoid valve 6 all are connected with controlling means 7. When the constant-speed high-level tank is used, pressure data can be obtained through the pressure sensor 2, a pressure value is set through the control device 7 when the constant-speed high-level tank is used, the constant discharging speed can be ensured when the pressure value at the discharging port 12 is constant, and when the pressure value measured by the pressure sensor 2 is reduced, the first electromagnetic valve 4 is controlled to be opened to fill gas into the air bag 3, so that the pressure value can be increased, and the pressure value is maintained to be constant; when the material is fed from the feeding hole 11, when the pressure value measured by the pressure sensor 2 rises, the second electromagnetic valve 6 is controlled to open the air bag 3 to deflate, so that the pressure value can be reduced, the pressure at the discharging hole 12 is maintained at the set pressure, and the discharging hole 12 can discharge the material at a constant speed.
