[0023] Embodiment 1: A double-push double-outlet pusher centrifuge with an inverted cone feed pipe 1 structure, such as Figure 2 , including a feed pipe 1 and a fixed rod 11 fixedly arranged in the feed pipe 1. The fixed rod 11 and the feed pipe 1 are preferably coaxially arranged. One end of the fixed rod 11 extends out of the end of the feed pipe 1 located in the centrifuge and an inverted cone block 12 is provided at the extended end. The end of the inverted cone block 12 with a larger taper is distributed away from the feed pipe 1. The inverted cone block 12 and the fixed rod 11 are also coaxially arranged. At this time, the fixed rod 11 can be fixed to the inner wall of the feed pipe 1 by a plurality of connecting rods, and each connecting rod is axially arranged on the fixed rod 11.

[0024] like Figure 2 The inverted cone block 12 is fixed at the outlet of the feed pipe 1 by the fixing rod 11. At this time, the slurry flowing out of the feed pipe 1 hits the inverted cone block 12, and then enters the main distributor 3 for acceleration and distribution. The slurry can be well distributed, so that the inverted cone block 12 and the outlet position of the feed pipe 1 are fixed, reducing the occurrence of uneven distribution.

[0025] like Figure 1 and Figure 3 Alternatively, the fixed rod 11 is replaced by a fixed tube for introducing washing liquid, the fixed tube and the feed tube 1 are both horizontally distributed, one end of the fixed tube passes through the pushing plate 2 and a plurality of washing holes 13 are opened on the outer wall through which it passes, and the other end extends out of the feed tube 1 through the bent tube 14. At this time, the bent tube 14 and one end of the feed tube 1 are both located outside the centrifuge, the inverted cone block 12 is fixed on the outer wall of the fixed tube extending out of the feed tube 1, and the pushing plate 2 is provided with a through hole 21 for the fixed tube to pass through.

[0026] like Figure 1 and Figure 3At this time, washing liquid is transported to the fixed pipe through the bent pipe 14, and then the screen cylinder 4 inside the push plate 2 is cleaned through each washing hole 13, so that the fixed pipe can not only fix the inverted cone block 12, but also transport washing liquid.

[0027] like Figure 1 and Figure 3 and Figure 4 In application, the parts around the feed pipe 1 are arranged as follows: the feed pipe 1 is installed in a feed pipe 1 seat, the fixed pipe passes through a push plate 2, and the two sides of the push plate 2 are respectively provided with a main distributor 3 and an auxiliary distributor (for detailed structure, please see the patent content of the double-push and double-outlet solid-liquid separation structure for pusher centrifuge and its centrifuge, which is applied by the applicant with application number 2025102540479). The outside of the push plate 2 is a rotating drum 5, and the rotating drum 5 is equipped with a screen cylinder 4. The push chassis 6 performs rotary and reciprocating motions, and the push chassis 6 is located in the rotating drum 5; there are 8 pillars 61 on the push chassis 6, and the push plate 2 is installed on the pillars 61. After the centrifuge is finished working, materials will be retained inside the screen cylinder 4 and the main distributor 3. The washing hole 13 is for the convenience of cleaning the materials on the screen cylinder 4 inside the push plate 2; like Figure 5 and Figure 6 and Figure 7 In order to be able to clean the inside of the main distributor 3, the inverted cone block 12 includes a cone cylinder 121 fixedly arranged on the fixed pipe, the cone cylinder 121 is hollow inside, the cone surface of the cone cylinder 121 is a plurality of evenly spaced inclined plates 122, the inclination direction of each inclined plate 122 is along the taper direction of the cone cylinder 121, the fixed pipe is coaxially provided with a cone guide column 123 in the cone cylinder 121, the cone surface of the guide column 123 is in contact with the plate surface of each inclined plate 122, the fixed pipe is provided with a plurality of washing holes 124 on the outer wall in contact with the guide column 123, the guide column 123 is provided with a guide hole 125 connected with each washing hole, each inclined plate 122 closes a row of guide holes 125, so that the inclined plate 122 closes all the guide holes 125, and the fixed pipe is provided with a driving member that causes the guide hole 125 to be misaligned with the inclined plate 122.

[0028] like Figure 5 and Figure 6 and Figure 7 The fixed pipe is coaxially distributed with the feed pipe 1, and includes a first pipe 15 fixedly connected to the elbow 14 and a second pipe 16 connected to the first pipe 15 and rotatably connected to one end of the first pipe 15 away from the elbow 14. The first pipe 15 and the second pipe 16 are located on the same straight line, one end of the second pipe 16 passes through the push plate 2, and the washing hole 13 is opened on the second pipe 16, and the washing hole 2 124 is also set on the second pipe 16; like Figure 5 and Figure 6 and Figure 7One end of each inclined plate 122 on the conical cylinder 121 is fixedly connected through the annular plate 17, and the other end is fixedly connected to the bottom of the conical cylinder 121. The annular plate 17 is fixed on the first tube 15, so that the position of the conical cylinder 121 is fixed. The bottom of the conical cylinder 121 is rotatably connected to the second tube 16. The guide column 123 is fixedly arranged on the second tube 16, so that when the second tube 16 rotates, the guide column 123 is driven to rotate together.

[0029] like Figure 5 and Figure 6 and Figure 7 The driving member includes a curved and extended driving tube 18 arranged on the outer wall of the second tube 16. The driving tube 18 is curved and extended in a direction away from the outer wall of the second tube 16. There are a plurality of driving tubes 18 arranged in an axial array along the second tube 16. The number of driving tubes 18 after the array is completed is consistent with the number of washing holes 13 on the longitudinal section of the second tube 16, and each driving tube 18 is connected to the washing hole 13.

[0030] like Figure 5 and Figure 6 and Figure 7 , each guide hole 125 is an inclined hole, and the outlets are all toward the main distributor 3; when the washing liquid is not introduced into the fixed pipe, a reset member is provided at the bottom of the conical cylinder 121 to make the inclined plate 122 close the guide hole 125.

[0031] like Figure 5 and Figure 6 and Figure 7 The reset member includes a mounting groove 19 provided on the side with a larger taper of the guide column 123, the notch of the mounting groove 19 faces the bottom of the conical cylinder 121, the bottom of the conical cylinder 121 is a circular plate, and an extension column 191 extending toward the conical cylinder 121 is provided at the bottom of the mounting groove 19. A torsion spring 192 is installed in the mounting groove 19 on the outer wall of the second tube 16. The torsion spring 192 is sleeved on the outer wall of the second tube 16, and one end of the torsion spring 192 is fixed to the bottom of the conical cylinder 121, and the other end is fixed to the extension column 191. A blocking column (not shown in the figure) is provided at the bottom of the conical cylinder 121. When the second tube 16 rotates to drive the extension column 191 to collide with the blocking column, each column of guide holes 125 is dislocated and separated from the inclined plate 122.

[0032] Working principle: When the washing liquid is pumped into the first tube 15 and the second tube 16 through the curved tube 14, the washing liquid enters the driving tube 18 through the washing hole 13. Since the driving tube 18 is curved, the sprayed washing liquid is convenient for tilting the screen drum 4 on the one hand, and for driving the second tube 16 to rotate on the other hand, driving the guide column 123 to rotate. At this time, the guide hole 125 is misaligned with the inclined plate 122, so that the inclined plate 122 opens each guide hole 125, which is convenient for the washing liquid to be sprayed out from the washing hole 2 124 and the guide hole 125, and then sprayed to the main distributor 3, so as to achieve the cleaning of the materials in the main distributor 3; At this time, the extension column 191 conflicts with the blocking column, thereby limiting the continued rotation of the second tube 16, so that the guide hole 125 continues to spray out the washing liquid; when the washing liquid is blocked, the second tube 16 loses the power provided by the washing liquid, and the extension column 191 moves away from the blocking column under the action of the torsion spring 192, so that each column of the guide holes 125 rotates toward the corresponding inclined plate 122. When the torsion spring 192 is in a natural state, each inclined plate 122 closes each column of the guide holes 125 to facilitate the slurry to flow out of the feed pipe 1 again. At this time, the conical surface of the guide column 123 and each inclined plate 122 play a role in distributing and guiding the slurry.

[0033] The conical cylinder 121 and the guide column 123 are both made of stainless steel. Stainless steel has good corrosion resistance, can withstand large thrust and centrifugal force, has a smooth surface, and is easy to clean and maintain.

[0034] Embodiment 2: A double-push double-outlet pusher centrifuge, such as Figure 4 , including the above-mentioned embodiment 1.
