Description

Technical Field

[0001] The invention belongs to the field of conveying technology, and specifically relates to a material discharge device, and in particular to a liquid material discharge device and a material discharge method thereof. Background Art

[0002] During the process of liquid discharge, the liquid passes through the flow meter and then flows into the container through the lower end of the discharge pipe. The volume of the liquid flowing into the container is calculated based on the flow rate displayed by the flow meter.

[0003] However, in a traditional feeding pipe, it is unpredictable how much liquid is in the feeding pipe before the feeding starts. Therefore, there will be errors when the flow meter measures the volume of the liquid being fed.

[0004] When a traditional feed pipe transports liquid into a container, the liquid impacts the bottom wall or side wall of the container under the action of pressure and its own gravity; if the transported liquid is corrosive to a certain extent, the liquid with impact force directly impacts the bottom wall or side wall of the container, which will affect the service life of the container.

A liquid feeding device, characterized in that: include: A feeding pipe (1) having a hollow interior and arranged vertically; An adjusting member (2) is arranged at the lower end of the feeding tube (1) for lifting; A sealing member (3) is circumferentially arranged around the inner wall of the ring adjusting member (2); A plurality of sealing blocks (4), wherein the sealing blocks (4) are slidably arranged on the inner bottom wall of the adjusting member (2); The adjusting member (2) comprises: an adjusting disk (21) which is arranged below the feeding tube (1); A limiting ring (22) is arranged on the adjusting disk (21) and has an outer diameter smaller than the outer diameter of the feeding tube (1); The limiting ring (22) is provided with a plurality of discharge ports (24) corresponding to the sealing block (4); When the material is not being discharged, the sealing blocks (4) abut against each other to seal the discharge opening (10) of the discharge pipe (1); When discharging the material, the sealing block (4) slides outward to push the upper end of the sealing member (3) to tilt outward, and the sealing member (3) is suitable for guiding the liquid to spray obliquely upward; If the liquid flow rate in the discharge pipe (1) is less than a threshold value, the regulating member (2) moves upward to seal the discharge opening (10), so that the discharge pipe (1) is filled with liquid.

9. The liquid feeding device according to claim 8, characterized in that: A positioning column (20) is fixed to the upper end of the adjustment disk (21); The sealing block (4) is slidably arranged on the adjusting disk (21); The sealing block (4) slides inwards until it abuts against the positioning column (20) to seal the discharge port (10) of the discharge pipe (1); The sealing block (4) slides outwards until it abuts against the sealing member (3) to push the sealing member (3) to deform outwards.

10. The liquid feeding device according to claim 9, characterized in that: The inner bottom wall of the discharge port (10) is provided with a first inclined surface (12) along the circumferential direction; The side wall of the sealing block (4) is provided with a second inclined surface (40), and the first inclined surface (12) and the second inclined surface (40) are parallel to each other; When the adjusting disk (21) moves upward to reset, the first inclined surface (12) is suitable for pushing the second inclined surface (40) so that the sealing blocks (4) move towards each other to seal the discharge port (10).

11. The liquid feeding device according to claim 10, characterized in that: The sealing member (3) is in an "L" shape, and the outer wall of the horizontal section of the sealing member (3) abuts against the inner wall of the limiting ring (22); When the sealing block (4) slides radially outward, it pushes the vertical section of the sealing member (3) to bend and deform outward.

12. A material discharging method for a material discharging device, characterized in that: The liquid feeding device according to any one of claims 1 to 11 is used, comprising: When no material is being discharged, the sealing blocks (4) abut against each other to seal the discharge opening (10) of the discharge pipe (1); When discharging, when the liquid flows downward through the discharging pipe (1), the liquid pushes the regulating member (2) to move downward; When the adjusting member (2) moves downward, each sealing block (4) slides outward synchronously; The sealing block (4) pushes the upper end of the sealing member (3) to tilt outward, and the sealing member (3) is suitable for guiding the liquid to spray obliquely upward.
