[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: A double distributor structure of a double-push double-outlet pusher centrifuge, such as Figure 1 and Figure 2, including auxiliary distributors and main distributors that distribute the suspension slurry on the left and right sides of the push plate 2 respectively. The main distributor divides the suspension slurry into two parts, one of which flows evenly to the right side of the push plate 2 after passing through the main distributor (such as Figure 1 The slurry in the material flows to B, and the other part passes through the auxiliary distributor and is evenly distributed by the auxiliary distributor on the left side of the push plate 2 (such as Figure 1 The slurry in the material pusher plate flows to A). The pusher plate 2 is vertically distributed, and the left and right sides mentioned above are the left and right sides of the pusher plate 2 in the horizontal direction.

[0023] like Figure 1 and Figure 2 , the suspension slurry is passed into the main distributor, and the main distributor makes a part of the suspension slurry flow evenly to the right side of the push plate 2 after passing through the main distributor, and the other part passes through the auxiliary distributor and is evenly distributed on the left side of the push plate 2 by the auxiliary distributor, so that the distribution direction of the suspension slurry of the centrifuge is bidirectional distribution, so that the push plate 2 can push the material when moving left and right, thereby improving the discharge efficiency, and the uniform distribution reduces the vibration of the centrifuge, facilitates the formation of filter cakes, and reduces the water content of the solid phase.

[0024] like Figure 1 and Figure 4 In actual application, a drum 3 is arranged outside the push plate 2, the opening of the drum 3 is horizontally distributed, a screen cylinder 31 is arranged inside the drum 3, and a plurality of discharge holes 32 are circumferentially opened on the side of the drum 3 away from the opening of the drum 3. The opening of the drum 3 and the discharge holes 32 are arranged to facilitate the discharge of the solid phase material on the left and right sides of the push plate 2 in the drum 3. A push plate 331 is arranged inside the drum 3, and the push plate 2 is mounted on the support 34. A feed pipe 4 is built into the main distributor, and the suspension slurry passes through the feed pipe 4 and enters the main distributor for distribution and acceleration.

[0025] like Figure 1 and Figure 3 The main distributor includes a main body slidably connected to the outer wall of the feed pipe 4 and a chassis 1 arranged on one side of the main body. The main body includes an annular plate 11 slidably connected to the outer wall of the feed pipe 4 and a conical cylinder 12 coaxially arranged on one side of the annular plate 11. The taper of the conical cylinder 12 gradually moves away from the annular plate 11. An annular disk 13 is coaxially arranged at one end of the conical cylinder 12 away from the annular plate 11. A vertical cylinder 131 is coaxially arranged at one end of the annular disk 13 away from the conical cylinder 12. The chassis 1 is installed on the vertical cylinder 131 and the chassis 1 is arranged opposite to the annular disk 13. The chassis 1 is installed on the pushing disk 2, and then the main distributor is installed on the pushing disk 2. The vertical cylinder 131 is arranged close to the inner wall of the screen cylinder 31. like Figure 1 and Figure 3, a plurality of partitions 14 are arranged on the chassis 1, and the angle between the length direction of the partition 14 and the radial direction of the chassis 1 is 20°±3°, so that the slurry can flow along the partitions 14. One end of each partition 14 contacts the wall of the vertical cylinder 131, and the other end extends obliquely toward the center of the chassis 1. Two partitions 14 form a group. A material-passing hole 15 is provided on the outer wall of the vertical cylinder 131 between two adjacent groups of partitions 14. The two ends of the material-passing hole 15 are respectively distributed close to two adjacent partitions 14. The chassis 1 is provided with a material-passing hole 2 151 in each group of partitions 14. The two ends of the material-passing hole 2 151 in the length direction respectively extend to the opposite side of the two adjacent partitions 14. At this time, the material-passing hole 2 151 and the material-passing hole 1 15 are distributed at intervals and the number is the same.

[0026] like Figure 1 and Figure 3 The auxiliary material distributor includes a material through hole three 16 opened on the pushing plate 2 and corresponding to each material through hole two 151. The material through hole three 16 is connected to the material through hole two 151. Each material through hole two 151 is distributed close to the inner wall of the vertical cylinder 131. The pushing plate 2 is provided with a retaining ring 17 on the side away from the chassis 1. The longitudinal section of the retaining ring 17 is L-shaped. The horizontal part of the retaining ring 17 is fixedly connected to the surface of the pushing plate 2 and is vertically distributed opposite to the pushing plate 2. Each material through hole three 16 is distributed opposite to the vertical part of the retaining ring 17.

[0027] like Figure 1 and Figure 3 Working principle: After the feed pipe 4 passes the slurry into the drum 3, the slurry enters between the main body and the chassis 1. As the drum 3 and the screen cylinder 31 rotate together, the main body and the chassis 1 are also driven to rotate. At this time, the slurry enters the space formed by the conical cylinder 12, the annular disk 13, the vertical cylinder 131, and the chassis 1 through the feed pipe 4. A part of the slurry flows to one side of the push plate 2 along the feed hole 15, and the other part of the slurry flows to the push plate 2 along the feed hole 2 151 and the feed hole 3 16. The other side is then guided to the screen cylinder 31 by the retaining ring 17, realizing bidirectional material distribution on both sides of the push plate 2. The second material passage hole 151 and the first material passage hole 15 are spaced and distributed in the same number, thereby realizing uniform distribution of slurry on both sides of the push plate 2, and the slurry on both sides of the push plate 2 realizes solid-liquid separation. The solid phase material is pushed to both sides of the drum 3 by the reciprocating push plate 2, which is convenient for discharging. The solid phase material flowing out of the discharge hole 32 is led out by the discharge pipe provided on the centrifuge, which is opposite to the discharge hole 32. The push plate 2 pushes materials in two directions, and the pushing efficiency is increased to twice the original, and the output of the centrifuge is increased to about twice that of the traditional unidirectional pushing structure.

[0028] The main distributor and the auxiliary distributor solve the problem of uneven distribution, and also solve the problem of excessive vibration caused by uneven distribution of the centrifuge. The use of a long drum 3 can reduce the water content of the solid phase slurry.

[0029] like Figure 2 The baffle ring 17 includes an annular cylinder 171 coaxially distributed with the pushing disk 2 and an annular baffle plate 172 arranged at one end of the annular cylinder 171 away from the pushing disk 2. Each of the three material through holes 16 is opposite to the baffle plate 172. The annular cylinder 171 is installed on the pushing disk 2 by means of locking screws, and the baffle plate 172 is installed on the end surface of the annular cylinder 171 by means of mounting screws. At this time, it is convenient to replace and install the baffle plate 172 or the annular cylinder 171. An annular groove 18 is provided on the disk surface of the pushing disk 2, and one side of the annular groove 18 The groove wall extends out of the disk surface of the pushing disk 2, and one side of the annular cylinder 171 contacts the groove wall of the annular groove 18. At this time, it is convenient to install and position the annular cylinder 171, and one end of the baffle plate 172 extends out of the inner wall of the annular cylinder 171 and extends toward the inner wall of the annular cylinder 171.

[0030] like Figure 1 Alternatively, the retaining ring 17 is provided with an annular connecting ring 173 on the horizontal part of the retaining ring 17, the connecting ring 173 is in contact with the disk surface of the pushing disk 2, the connecting ring 173 is arranged on the inner wall of the retaining ring 17, and a plurality of connecting screws (not shown in the figure) are provided on the ring surface of the connecting ring 173, one end of the connecting screw is threadedly connected with the disk surface of the pushing disk 2, at this time, the connecting ring 173 can be installed on the pushing disk 2 through the connecting screws, and then the retaining ring 17 can be installed on the pushing disk 2.

[0031] The annular disk 13 is installed on the partition 14 by fastening screws. One end of the vertical cylinder 131 is in contact with the chassis 1 and is provided with an annular sealing plate entering the chassis 1. The other end is welded to the outer wall of the annular disk 13. At this time, the vertical cylinder 131 is first welded to the annular disk 13, and then the annular disk 13 is installed on the partition 14 on the chassis 1.

[0032] Each partition 14 is mounted on the chassis 1 by a plurality of limit screws (not shown in the figure), and the nut of the limit screw is located on the side of the chassis 1 away from the partition 14. The limit screw passes through the chassis 1 and is threadedly connected to the partition 14, so as to facilitate the replacement of a partition 14. During installation, each partition 14 is first mounted on the chassis 1, and then the chassis 1 is mounted on the push plate 2 by screws, and then the annular plate 13 with the vertical cylinder 131 is installed.

[0033] like Figure 1 and Figure 4A washing pipe 41 is passed through the feed pipe 4, one end of the washing pipe 41 passes through the pushing plate 2, and the other end is provided with a bent pipe 44 that bends and passes through the feed pipe 4. A plurality of washing holes 42 are opened on the outer wall of the washing pipe 41 passing through the pushing plate 2, and detergent is introduced through the bent pipe 44 and the washing pipe 41, so as to facilitate the cleaning of the drum 3 and the screen cylinder 31 on the left side of the pushing plate 2; an inverted cone block 43 is provided on the outer wall of the washing pipe 41, and the side with a larger taper of the inverted cone block 43 is distributed close to the pushing plate 2, and the side with a smaller taper is distributed close to the feed pipe 4, which can reduce the slurry from passing through the hole in the middle of the pushing plate 2 and entering the drum 3.
