Description

Technical Field

[0001] This utility model relates to the field of porcelain clay molding technology, specifically to a porcelain clay molding device. Background Technology

[0002] The plunger pump uses hydraulic pressure to drive the ceramic plunger in reciprocating motion, creating a pressure difference to achieve efficient intake and discharge of ceramic slurry, ensuring stable delivery of the slurry to the molding die area. The wear-resistant properties of the ceramic plunger (such as alumina material) can withstand long-term friction from ceramic slurry with high solids content, extending the equipment's lifespan.

[0003] In traditional ceramic forming processes, clay transportation often suffers from problems such as large pressure fluctuations and impurity residues. While existing technologies, such as centrifugal forming devices, can achieve defoaming, they are ill-suited to the high-pressure transportation requirements of high-solids-content (>70%) ceramic clay. Plunger pumps, which hydraulically drive ceramic plungers (made of alumina) in reciprocating motion to create a stable pressure difference, achieve efficient clay intake and high-pressure discharge. However, conventional plunger pumps tend to produce pulsating flow at the discharge point, resulting in insufficient clay uniformity and uneven mold filling. Utility Model Content

[0004] The purpose of this invention is to provide a clay molding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a porcelain clay forming device, comprising a base plate, a plunger pump installed on one side of the top of the base plate, the discharge end of the plunger pump being connected to a discharge pipeline, and a vortex assembly provided at the end of the discharge pipeline; the vortex assembly comprising a flange end, a mounting cylinder, and a discharge end, and vortex fans symmetrically arranged inside the mounting cylinder, the vortex fans being composed of a frame and internal adjustable speed vortex blades, the blade inclination angle of the vortex blades being 15°-45°.

[0006] The base plate is also equipped with a hydraulic unit on top, and the hydraulic unit is connected to a plunger pump through a pressure pipe.

[0007] The plunger pump has a feed pipe on the other side, and a buffer tank is installed on the outer wall of the top side of the feed pipe through a flange.

[0008] The feed pipeline has a filter assembly installed at one end via a flange. The filter assembly includes a filter cylinder, and a drain valve is threadedly connected to the bottom end of the filter cylinder.

[0009] The filter cylinder has an end cap threaded to its top, and the filter cylinder is filled with a filter element.

[0010] The filter cylinder has a feed pipe threaded to one end, and a connecting pipe threaded to the outer wall of one side of the filter cylinder. One end of the connecting pipe is fixedly connected to one end of the feed pipe by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes the centrifugal force generated by the adjustable-speed swirl vanes in the swirl assembly to effectively eliminate air bubbles and uneven density in the ceramic clay, significantly improving the stability of the clay flow and ensuring uniform mold filling. Furthermore, the adjustable-speed design of the swirl vanes, combined with the pressure regulation of the hydraulic unit, allows for compatibility with ceramic clays of various moisture contents, meeting diverse molding needs from fine ceramics to coarse pottery. The filter assembly of this invention employs a filter element connected to a threaded drain valve, enabling the cleaning of impurities without shutting down the machine, reducing the risk of equipment blockage and extending the filter element's lifespan.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model provides a technical solution: a porcelain clay forming device, including a base plate 1, a plunger pump 3 installed on one side of the top of the base plate 1, the discharge end of the plunger pump 3 connected to the discharge pipe 4, and a vortex assembly 5 provided at the end of the discharge pipe 4; the vortex assembly 5 includes a flange end 9, a mounting cylinder 10, and a discharge end 12, and vortex fans 11 are symmetrically arranged inside the mounting cylinder 10. The vortex fans 11 are composed of a frame 13 and internal adjustable speed vortex blades 14, and the blade inclination angle of the vortex blades 14 is 15°-4°. At 5°, a hydraulic unit 2 is also provided on the top of the base plate 1. The preferred model of the hydraulic unit 2 is HYU-60. The hydraulic unit 2 drives the ceramic plunger of the plunger pump 3 to reciprocate, forming a high-pressure mud flow of 10-15MPa, which is pushed to the cyclone assembly 5 through the discharge pipe 4. The symmetrically arranged cyclone fan 11 rotates at an adjustable speed. The centrifugal force generated by the blade tilt angle of 15°-45° makes the mud density uniform and the bubble removal rate ≥95%. The hydraulic unit 2 is connected to the plunger pump 3 through a pressure pipe.

[0021] The plunger pump 3 has a feed pipe 6 on the other side, and a buffer tank 7 is installed on the outer wall of the top side of the feed pipe 6 via a flange. The buffer tank is connected to the feed pipe 6 via a flange, and its volume buffering characteristics are used to balance the suction pulse pressure of the plunger pump 3, reducing the impact of hydraulic fluctuations on the uniformity of the mud. A filter assembly 8 is installed at one end of the feed pipe 6 via a flange. The filter assembly 8 includes a filter cylinder 16, and a drain valve 20 is threaded to the bottom end of the filter cylinder 16. The drain valve 20 has a vibration motor at the bottom end, and an end cap 17 is threaded to the top end of the filter cylinder 16. The filter cylinder 16 is filled with... The filter element 19 has a multi-stage structure. The filter assembly 8 uses a threaded filter cylinder 16 and a detachable filter element 19. With the bottom drain valve 20, it can quickly clean impurities and replace the filter element, improving maintenance efficiency. One end of the filter cylinder 16 is threadedly connected to the feed pipe 18. The ceramic clay raw material enters the filter assembly 8 through the feed pipe 18. After the multi-stage filter element 19 intercepts impurities, the cleaned mud is transported to the buffer tank 7 through the connecting pipe 15. The outer wall of one side of the filter cylinder 16 is threadedly connected to the connecting pipe 15, and one end of the connecting pipe 15 is fixedly connected to one end of the feed pipe 6 by bolts.

[0022] Working principle: The porcelain clay raw material enters the filter assembly 8 through the feed pipe 18. After impurities are intercepted by the multi-stage filter element 19, the cleaned slurry is transported to the buffer tank 7 through the connecting pipe 15. The buffer tank is connected to the feed pipe 6 through the flange to balance the suction pulse pressure of the plunger pump 3. The hydraulic unit 2 drives the ceramic plunger of the plunger pump 3 to reciprocate, forming a negative pressure to suck in the slurry and pressurize it to 10-15MPa. It is then pushed to the cyclone assembly 5 through the discharge pipe 4. During this process, the buffer tank 7 continuously compensates for pressure fluctuations to ensure flow stability. After the high-pressure slurry enters the mounting cylinder 10, the symmetrically arranged cyclone fans 11 rotate. The centrifugal force generated by the blade tilt angle of 15°-45° makes the slurry density uniform and the bubble removal rate ≥95%. The homogenized slurry is discharged from the discharge end 12. The homogenized slurry is injected into the mold through the external pipe connected to the flange end 9. During the molding process, the hydraulic unit 2 dynamically adjusts the pressure according to the molding requirements to adapt to the molding process requirements of porcelain clay with different moisture contents of 30%-75%.
