Taking the self-opening valve 500 installed at the discharge port of the first discharge pipe 130 as an example, the self-opening valve 500 comprises a round shaft 510 rotatably installed at the top of the discharge port of the first discharge pipe 130, the bottom of the round shaft 510 is welded with an outer valve body 520, the inner side of the outer valve body 520 is integrally formed with an inner valve body 530, the bottom of the inner valve body 530 is provided in a fan shape, the inside of the first discharge pipe 130 is provided with an arc-shaped groove 540 abutting with the inner valve body 530, when the outer valve body 520 abuts with the first discharge pipe 130, the inner valve body 530 is inserted into the inside of the first discharge pipe 130, and the bottom of the inner valve body 530 abuts with the arc-shaped groove 540. The round shaft 510 is rotatably connected with the U-shaped frame 511 through a pin shaft, the first discharge pipe 130 is provided with a slot for inserting the U-shaped frame 511, and the first discharge pipe 130 is connected with the U-shaped frame 511 through a screw 512.

Under the action of its own gravity, the outer valve body 520 and the inner valve body 530 are closed. The bottom of the inner valve body 530 is provided in a fan shape, the inside of the first discharge pipe 130 is provided with an arc-shaped groove 540 abutting with the inner valve body 530, when the outer valve body 520 abuts with the first discharge pipe 130, the inner valve body 530 is inserted into the inside of the first discharge pipe 130, and the bottom of the inner valve body 530 abuts with the arc-shaped groove 540.

[0038] Structure principle:

[0039] In use, the first feeding pipe 121 and the second feeding pipe 221 are communicated with the raw material supply pipe, and the first discharge pipe 130 and the second discharge pipe 230 are communicated with the feeding pipe of the filter press;

[0040] As Figure 1As shown in the figure, the arrow indicates the direction of raw material flow. When the oil cylinder 300 drives the connecting rod 301 to drive the first piston 110 and the second piston 210 to move downward, under the action of pressure, the outer valve body 520 and inner valve body 530 of the self-switching valve 500 inside the first conveying pipe 121 and the second discharge pipe 230 are pushed open, while the other two self-switching valves 500 are in the closed state. Under the action of pressure, the first housing 100 draws in raw material from the first conveying pipe 121, and the raw material inside the second housing 200 is squeezed out through the second discharge pipe 230.

[0041] like Figure 2 As shown, when the hydraulic cylinder 300 drives the connecting rod 301 to drive the first piston 110 and the second piston 210 to move upward, under the action of pressure, the self-closing valve 500 inside the first conveying pipe 121 and the second discharge pipe 230 is in a closed state, and the outer valve body 520 and inner valve body 530 of the other two self-closing valves 500 are pushed open. Under the action of pressure, the raw material inside the first housing 100 is squeezed out through the first discharge pipe 130, and the second housing 200 draws in the raw material from the second conveying pipe 221.

[0042] In summary:

[0043] The first piston 110 and the second piston 210 are driven up and down by the hydraulic cylinder 300. The first housing 100 and the second housing 200 alternately suck in and discharge raw materials, providing continuous and efficient feeding for filter presses or other equipment. One extension and retraction of the telescopic rod can supply material twice. By increasing the number of second housings 200, one extension and retraction can supply material multiple times, greatly improving the feeding efficiency.

[0044] The rotation of the circular shaft 510 facilitates the opening of the outer valve body 520 and the inner valve body 530. Under their own weight, the outer valve body 520 and the inner valve body 530 will close. The bottom of the inner valve body 530 is fan-shaped. The inside of the first discharge pipe 130 is provided with an arc-shaped groove 540 that fits with the inner valve body 530. When the outer valve body 520 abuts against the first discharge pipe 130, the inner valve body 530 is inserted into the inside of the first discharge pipe 130. The bottom of the inner valve body 530 fits with the arc-shaped groove 540, which greatly improves the sealing performance when the valve is closed.

[0045] The distance between the first housing 100 and the second housing 200 can be easily adjusted using the length adjustment component.

[0046] It should be noted that the number of second shells 200 can be increased to improve the material conveying efficiency.

[0047] The above merely describes preferred embodiments of the present application, and is not intended to limit the implementation and protection scope of the present application. For those skilled in the art, it should be understood that any equivalent substitutions and obvious changes made according to the content of the present application and drawings should be included in the protection scope of the present application.
