Embodiment Construction
[0013] Attached Figure 1~3 As shown, it is a preferred embodiment of the high-pressure closed-type cutting device dedicated to high-pressure conveying according to the present invention, which includes a material storage cylinder 1 and a traction cylinder 2, and the bottom of the material storage cylinder 1 is provided with a discharge port 3. A closed cut-off plate 4 is horizontally interspersed on the storage cylinder 1 at a position close to the bottom of the storage tank 1. The closed cut-off plate 4 is provided with a communication hole 5 opposite to the discharge port 3 up and down. The closed cut-off plate 4 The top is provided with an upper PTFE gasket 6 that compresses and seals the cut-off plate 4, and the lower PTFE gasket 7 is arranged below the closed cut-off plate 4. Several upper compression limiters are evenly distributed on the top of the upper PTFE gasket 6. Bit groove 8, the bottom end of lower PTFE gasket 7 is evenly distributed with several lower compres...

The invention aims at providing a high pressure closed type cutting-off device special for high pressure material conveying, wherein the high pressure closed type cutting-off device is reasonable in structure, easy to machine, accurate and reliable in action, convenient to adjust, good in sealing performance and capable of conducting self-cleaning and self-clearing on a cutting edge. The high pressure closed type cutting-off device special for high pressure material conveying comprises a material storage cylinder and a traction air cylinder. A discharging opening is formed in the bottom of the material storage cylinder. A closed cutting-off plate is horizontally arranged at the position, close to the bottom end of the material storage cylinder, of the material storage cylinder in an inserted manner. The closed cutting-off plate is provided with a communicating hole which is vertically opposite to the discharging opening. An upper polytetrafluoroethylene sealing gasket for compressing the closed cutting-off plate is arranged above the closed cutting-off plate, and a lower polytetrafluoroethylene sealing gasket is arranged below the closed cutting-off plate. Multiple upper compression limiting grooves are uniformly formed in the top end of the upper polytetrafluoroethylene sealing gasket.
Description
technical field [0001] The invention relates to a high-pressure feeding device, in particular to a high-pressure closed cutting device dedicated to high-pressure feeding. Background technique [0002] The fully degradable electronic transfer tray is an upgraded product that replaces non-degradable plastic products. It is one of the effective ways to control "industrial white pollution". The biomass material synthesized by modified starch + agricultural straw fiber has excellent environmental friendliness. The finished product has excellent performance, low cost, and can be produced industrially on a large scale. It is a new type of material with great commercial value and development prospects. [0003] The fully degradable electronic component transfer tray is mainly made of modified starch and agricultural straw fiber. Since the production process adopts the fusion technology of normal temperature water, the wet dough has a certain viscosity and is relatively dry, so the f...
