DETAILED DESCRIPTION

[0017] Below by embodiment, and in conjunction with the accompanying Figure 1-2 , the technical solution of the present invention is further specifically described.

[0018] A pigment processing device includes a closed rectangular box 1:

[0019] A cylinder 2 is provided in the middle of the bottom of the box body 1, and a one-way air inlet pipe I3 ​​is provided on the bottom wall of the box body 1 in the opening of the cylinder 2. A barrel body I4 extending to the outside of its top is further provided in the cylinder 2. A grid plate 5 is provided on the barrel body I4, which is against the inner wall of the box body 1. The grid plate 5 is located above the cylinder 2. An airbag layer 6 is provided on the top of the grid plate 5. The airbag layer 6 is connected to the bottom of the side wall of the cylinder 2 through a corrugated hose I7. A solenoid valve I8 is provided on the corrugated hose I7. A one-way air outlet pipe I9 and a corrugated hose II11 connected to the one-way air inlet pipe II10 at the bottom of the box body 1 are also provided on the bottom wall of the barrel body I4;

[0020] A barrel body II12 is provided at the top of the box body 1, and the side wall of the upper half of the barrel body II12 is a mesh structure. A rotating shaft 14 driven by a motor 13 is provided in the barrel body II12, and the bottom end of the rotating shaft 14 passes through the barrel body II12 and the bottom wall of the barrel body I4 in sequence. A thread is provided on the rotating shaft 14 below the barrel body II12, wherein a spiral tube 15 screwed to the thread is provided on the bottom wall of the barrel body I4, and an air passage 16 connected to the outer side of the bottom thereof is vertically provided in the rotating shaft 14. A stirring paddle 17 and a one-way air outlet pipe II18 located in the barrel body II12 are also provided on the rotating shaft 14, and the one-way air outlet pipe II18 is connected to the air passage 16.

[0021] like Figure 1 、 2 As shown, an exhaust pipe 19 is provided on the corrugated hose I7 between the solenoid valve I8 and the airbag 6, and a solenoid valve II20 is provided on the exhaust pipe 19. The corrugated hose I7 is fixedly connected to the side wall of the cylinder 2 below the barrel body I4.

[0022] In this embodiment, a discharge pipe 21 is provided on the side wall of the box body 1 above the grid plate 5, and a slag discharge pipe 23 is provided at the bottom of the box body 1, which penetrates the bottom wall of the barrel body I4 and communicates with the bottom of the barrel body II12.

[0023] In this embodiment, the bottom end of the rotating shaft 14 is fixed to the inner bottom wall of the box body 1 through a bearing, and a connecting pipe 23 connected to the air vent 16 is provided at the bottom of the side wall of the rotating shaft 14, and the connecting pipe 23 is located below the barrel body I4.

[0024] In this embodiment, the size of the barrel body I4 is adapted to the size of the internal opening of the cylinder 2, and the size of the barrel body II12 is adapted to the size of the internal opening of the barrel body I4.

[0025] In this embodiment, multiple groups of stirring paddles 17 and one-way air outlet pipes II18 are evenly arranged on the outer wall of the rotating shaft 14 in the barrel body II12, and a feed pipe 24 connected to the barrel body II12 is provided on the top wall of the box body 1.

[0026] When in use, the one-way air inlet pipe II10 is opened to allow gas to be injected into the cavity formed between the barrel body I4 and the barrel body II12. When the raw materials are slowly introduced into the barrel body II12 through the feed pipe 24, the motor 13 drives the stirring paddle 17 to rotate through the rotating shaft 14 to stir and mix the raw materials slowly filled into the barrel body II12. In this process, the thread on the rotating shaft 14 rotates in the spiral tube 15 to drive the barrel body I4 and the grid plate 5 to move upward, so that the slowly moving barrel body I4 gradually covers the aperture on the side wall of the barrel body II12 to prevent the raw materials from flowing out of the aperture on the side wall of the barrel body II12 without mixing when the liquid level in the barrel body II12 gradually rises. When the barrel body I4 moves upward, its bottom wall is opened. The hole slides on the slag discharge pipe 22, and at the same time stretches the corrugated hose II11. When the barrel body I4 moves upward, it squeezes the gas in the cavity formed between the barrel body I4 and the barrel body II12, so that the gas is pressurized and flows from the one-way air outlet pipe I9 to the cavity formed between the barrel body I4, the cylinder 2 and the bottom wall of the box body 1, and then enters the air permeable channel 16 through the connecting pipe 23 and is discharged into the barrel body II12 by a plurality of one-way air outlet pipes II18, so as to achieve the purpose of pneumatic stirring of the raw materials in the barrel body II12. While the raw materials are physically stirred by the stirring paddle 17, the raw materials are also pneumatically stirred by the gas ejected through the one-way air outlet pipe II18, thereby effectively improving the stirring and mixing effect and efficiency of the raw materials.

[0027] During the above process, the gas in the cavity formed between the barrel body I4 and the barrel body II12 is discharged into the cavity formed between the barrel body I4, the cylinder 2 and the bottom wall of the box body 1 through the one-way air outlet pipe I9. At the same time, when the barrel body I4 moves upward, a suction force is generated in the cylinder 2, so that the external gas is extracted through the one-way air inlet pipe I3 ​​to forcibly fill the cavity formed between the barrel body I4, the cylinder 2 and the bottom wall of the box body 1. Then, most of the gas in the cavity enters the air permeable channel 16 through the connecting pipe 23 and is discharged by the one-way air outlet pipe II18, thereby playing a pneumatic stirring role on the raw materials in the barrel body II12.

[0028] like Figure 2 As shown, when the barrel body I4 moves up to the top, the motor 13 reverses, and continues to stir the raw materials in the barrel body II12 through the rotating shaft 14 and the stirring paddle 17, while it also indirectly drives the barrel body I4 to move down and reset. At this time, the mixed liquid raw materials in the barrel body II12 will overflow to the top of the grid plate 5 on the outside through the aperture gradually exposed on the side wall of the barrel body II12, and the large volume of granular raw materials will be filtered in the barrel body II12 to achieve a filtering effect on the raw materials. At the same time, the downward movement of the barrel body I4 will squeeze the gas in the cavity formed by the barrel body I4, the cylinder 2 and the bottom wall of the box body 1, so that the gas inside the cavity quickly enters the air permeable channel 16 through the connecting pipe 23 and is discharged by the one-way air outlet pipe II18, thereby playing a pneumatic stirring role on the raw materials in the barrel body II12;

[0029] The raw materials can be further circulated and mixed again. The steps are as follows: the motor 13 rotates forward to indirectly drive the barrel body I4 and the grid plate 5 to move up to a certain extent, so that the top of the barrel body I4 side wall is higher than the liquid level in the barrel body II12. At this time, the raw materials above the grid plate 5 on the outside of the barrel body II12 can flow into the inside through the aperture of the barrel body II12 side wall, and then the stirring paddle 17 and the gas stir and mix the re-mixed raw materials. At the same time, when the barrel body I4 and the grid plate 5 move up, the solenoid valve I8 is opened. At this time, the barrel body I4 The gas in the cavity formed between the barrel body II12 is forcibly introduced into the cavity formed between the barrel body I4, the cylinder 2 and the bottom wall of the box body 1 by the one-way air outlet pipe I9. Part of the gas in the cavity enters the air permeable channel 16, while part of the gas enters the air bag layer 6 through the opened corrugated hose I7 to fill it and expand it, so that the air bag layer 6 pushes the raw materials above the grid plate 5 to move upward to overflow the top of the side wall of the barrel body I4, so that the raw materials re-enter the barrel body II12 for circulation, stirring and mixing;

[0030] Next, the motor 13 reverses and indirectly drives the barrel body I4 and the grid plate 5 to move downward, and at the same time closes the solenoid valve I8 and opens the solenoid valve II20 to exhaust the air bag layer 6 through the exhaust pipe 19 to shrink it. Then, as the barrel body I4 moves downward, the raw materials in the barrel body II12 flow out from the aperture of the side wall of the barrel body II12, thereby filtering the raw materials that exceed the standard. Finally, Figure 1 As shown, the filtered raw materials can be discharged through the discharge pipe 21, and the raw materials filtered in the barrel II12 can be discharged through the opened slag discharge pipe 22.

[0031] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
