[0033] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0034] A large-scale manual slag-cleaning type separator drum rapid slag discharge device, such as Figure 1 As shown, the device includes a drum body 1, a drum cover 2, and a separation chamber formed between the drum cover 2 and the drum body. Several discs 3 are stacked in sequence in the separation chamber. The inner wall of the drum body 1 has a conical structure, and a slag discharge structure is provided at the bottom of the conical structure. The slag discharge structure is evenly arranged around the circumference of the drum body 1. The slag discharge structure includes a discharge port 4 that is radially arranged through the drum body 1. A screw plug structure is provided in the discharge port 4. The screw plug structure is used to close or open the discharge port 4. The inner wall of the discharge port 4 is provided with internal threads. The discharge port 4 is a stepped hole 5 with a T-shaped cross-section. The large diameter circle of the stepped hole 5 is located on the outside of the drum body 1, and the internal threads are provided on the inner wall of the large diameter circle.

[0035] Furthermore, the plug structure includes a bolt 6 and an O-ring 32. The bolt 6 includes a nut 7 and a insert 8. The insert 8 is located at the center of one side of the nut 7, and the insert 8 mates with the small-diameter circle of the stepped hole 5. The nut 7 has an annular groove on the side where the insert 8 is located, and the O-ring 32 is placed in the annular groove. The other side of the nut 7 has an internal hexagonal groove. The nut 7 is a flat cylindrical shape with external threads on its outer circumference. The upper conical surface angle of the conical structure is 2.5°, and the lower conical surface angle is 5°.

[0036] In the prior art, the inner wall of the drum body 1 is straight, such as... Figure 10 As shown, its sidewalls lack a rear slag discharge structure, requiring complete disassembly from the top for manual slag removal during use. This is a labor-intensive and time-consuming process, especially for large separators. The problem is even more pronounced during manual slag removal, where cleaning a large separator drum typically requires two people and 16 hours. In the specific implementation of this embodiment, as follows...Figure 1 As shown, the inner wall of the rotary drum is designed as a cone, the upper cone angle is 2.5°, and the lower cone angle is 5°. The design of this structure makes the slag phase deposit along the upper and lower cone to the middle. A plurality of discharge ports 4 are designed at the junction of the two cones, the discharge ports 4 are uniformly distributed along the circumference of the rotary drum, and a screw plug structure is arranged on the discharge ports 4. Specifically, the rotary drum body 1 is connected with the screw plug structure through threads. Specifically, the screw plug includes a bolt 6 for sealing the discharge port 4, a plug rod 8 is inserted into a small diameter circle inside the discharge port 4, a nut 7 is threadedly connected with a large diameter circle, and an O-ring seal is installed between each nut 7 and the rotary drum body 1 for sealing. The material of the bolt 6 is TA3 titanium alloy with high strength and low density, which reduces the self centrifugal force of the bolt 6 during operation of the separator, prevents the bolt 6 from being thrown out of the rotary drum body 1, and improves the safety of equipment operation.

[0037] During normal operation of the separator, the bolt 6 is screwed onto the rotary drum body 1, and the O-ring seal between the bolt 6 and the rotary drum body 1 can ensure that no material leaks out of the rotary drum. When it is necessary to clean the rotary drum, stop feeding and the separator, and after the rotary drum is completely stationary, unscrew the four bolts 6 on the rotary drum body 1. Run the separator at low speed, usually at 200-300 r / min, and the slag phase deposited in the rotary drum is quickly discharged from the four discharge ports 4 under the action of centrifugal force; a small amount of cleaning liquid is introduced into the rotary drum, and the flow rate of the cleaning liquid is about 2-4 m 3 / h; the cleaning liquid washes away the residual slag phase on the distributor, the disc 3, the rotary drum cover 2 and other parts, and finally discharges from the discharge port 4; every 10 minutes, switch the rotation direction of the rotary drum, which is more conducive to cleaning the slag phase in the rotary drum. Example Two

[0038] In example one, the bolt 6 must be removed before the slag discharge operation can be performed. In actual use, due to the small space outside the discharge port 4, it is not convenient to disassemble and install the bolt 6. Therefore, the present embodiment further improves the slag discharge operation without disassembling the screw plug structure.

[0039] Specifically, as Figure 2As shown, the screw plug structure includes a spring 9, an inner seal 10, and a limiting component 11 arranged sequentially from the inside to the outside. The inner seal 10 and the limiting component 11 are pressed together by their mating surfaces to form a seal on the discharge port 4. The limiting component 11 is fixedly installed inside the discharge port 4. The inner seal 10 has a cylindrical structure. The spring 9 applies a force to the inner seal 10, pressing it against the mating surface. The sidewall of the discharge port 4 is connected and evenly spaced with multiple side drain pipes 12. The inlet of one end of each side drain pipe 12 is evenly arranged around the discharge port 4, and the outlet of the other end is located on the outer wall of the drum body 1, so that the multiple side drain pipes 12 form a slag discharge channel that connects the inside and outside of the drum body 1. The inner seal 10 has an opening 13 at one end facing the inside of the drum body 1. The sidewall of the opening 13 has a through hole 14, which mates with the side drain pipe 12. In actual use, the mating surface can be as follows: Figure 2 The trapezoidal cross-section shown can also be a spherical cross-section, or as... Figure 4 As shown in the planar cross section, during slag removal, the slag phase is guided into the discharge port 4 by the conical side and enters the opening 13. When the through hole 14 provided on the side of the opening 13 is connected to the side discharge pipe 12, the slag discharge operation is formed.

[0040] In this embodiment, the inner seal 10 controls the opening of the side drain pipe 12 through rotation. The inner seal 10 and the limiting component 11 are divided into a first preset position and a second preset position according to their relative rotation angle, such as... Figure 3 As shown in A, the second preset position is as follows. Figure 3 As shown in Figure B, the first preset position is when the inner seal 10 and the limiting component 11 are in the first preset position, the through hole 14 and the side discharge pipe 12 are misaligned. At this time, because the through hole 14 and the side discharge pipe 12 are not connected, slag discharge cannot be performed. This preset position is used during normal centrifugal separation of the drum body 1. When the through hole 14 is in the second preset position and the inlet of the side discharge pipe 12 is aligned, as shown in Figure B... Figure 3 As shown in Figure A, the through hole 14 connects to the side drain pipe 12, which facilitates slag discharge.

[0041] like Figure 4 As shown, the outer end of the discharge port 4 is provided with a drive unit for controlling the rotation of the inner seal 10; the drive unit includes a drive rod 15 and a drive handle 16. The drive rod 15 is fixedly connected to the end of the inner seal 10, and the drive rod 15 passes through the limiting component 11 and is connected to the drive handle 16 on the outer side of the discharge port 4. In actual use, by twisting the drive handle 16, the inner seal 10 is driven to rotate by the drive rod 15, thereby changing the inner seal 10 between two preset positions.

[0042] As a further optimization improvement in the embodiment, when operating in the narrow space outside the discharge port 4, it is not intuitive to understand the angle of rotation of the inner sealing element 10. In order to avoid the misalignment problem caused by insufficient or excessive rotation, a rotation angle control part for the inner sealing element 10 is provided at the joint surface in the embodiment. The rotation angle control part includes an elastic protruding pin 17, an arc-shaped groove 18, and a limiting groove 19. The elastic protruding pin 17 is arranged on the limiting part 11, and the action end of the elastic protruding pin 17 elastically expands and contracts along the axis direction of the discharge port 4. The inner sealing element 10 is provided with the arc-shaped groove 18 matched with the elastic protruding pin 17. The inner bottom of the two ends of the arc-shaped groove 18 is provided with the limiting groove 19. As shown in Figure 4 、 Figure 5 , in actual use, the action end of the elastic protruding pin 17 is placed in the arc-shaped groove 18, and the circular arc angle of the arc-shaped groove 18 is the rotation angle range of the inner sealing element 10 relative to the limiting part 11. The limiting grooves 19 at both ends are the positioning points of the two preset positions. When the inner sealing element 10 rotates relative to the limiting part 11, when reaching the first preset position, the elastic protruding pin 17 is clamped into the corresponding limiting groove 19. At this time, the through hole 14 and the side discharge pipe 12 are misaligned with each other, and the discharge port 4 is closed for normal centrifugal operation. In the state of centrifugation, the inner sealing element 10 is pressed to the limiting part 11 side under the action of centrifugal force, which can enhance the sealing performance. When slagging is needed, the rotating drive handle 16 is rotated, and the inner sealing element 10 can be rotated through the drive rod 15, so that the elastic protruding pin 17 moves in the arc-shaped groove 18 relative to the inner sealing element 10. When moving to the other end of the arc-shaped groove 18, the elastic protruding pin 17 is clamped into the limiting groove 19 at the end, and at this time, the second preset position is reached, so that the through hole 14 and the side discharge pipe 12 are aligned, and at this time, the slagging operation can be performed. The cooperation of the limiting groove 19 and the elastic protruding pin 17 can make the inner sealing element 10 have good segmentation when rotating, and the rotation angle can be accurately controlled. Embodiment Three

[0043] As another control form of the inner sealing element 10, in the embodiment two, the rotating drive handle 16 is rotated to complete the operation in the narrow space. In the embodiment, the opening and closing of the discharge port 4 is completed by pressing the drive handle 16.

According to the axial displacement of the inner sealing element 10, it is divided into a first preset position and a second preset position. When the inner sealing element 10 is tightly attached to the limiting part 11, it is the first preset position, and the through hole 14 and the inlet of the side discharge pipe 12 are misaligned along the axis direction. When it is in the second preset position, the through hole 14 and the inlet of the side discharge pipe 12 are aligned. Figure 6The first preset position is shown in the middle A, at this time, the side pipe 12 is misaligned with the through hole 14 in the axial direction, so that the discharge port 4 can be sealed, Figure 6 As shown in the middle B, the inner sealing element 10 is pushed inward and positioned by pressing the driving handle 16, at this time, it is located in the second preset position, the through hole 14 is aligned with the side pipe 12, and the slag discharge operation can be quickly controlled.

[0045] In the first preset position, the distance between the plane where the inlet of the inner wall of the discharge port 4 is located and the plane where the through hole 14 is located is the action stroke 20 of the inner sealing element 10.
