Description

Technical Field

[0001] This invention relates to the field of centrifuge technology, specifically to a two-stage piston pusher centrifuge that can monitor the sealing performance in real time during operation. Background Technology

[0002] The two-stage piston pusher centrifuge is a continuously operating, hydraulically pulsed discharge filter centrifuge. It performs all operations, such as feeding, separation, washing, drying, and discharging, at full speed. The reciprocating motion of the pusher disc is controlled by the piston moving left and right by the reversing valve rod caused by the pressure oil pushing the piston to move and collide with it.

[0003] During operation, the pushing action of the material being spun out in a two-stage piston centrifuge can cause wear between the pusher plate and the centrifuge drum. This wear can lead to leaks, resulting in material loss, environmental pollution, and even health hazards for operators. Incomplete material separation also affects product quality and yield. Furthermore, the inability of the centrifuge to automatically detect leaks necessitates increased energy consumption to maintain operation, further increasing power consumption. Repeated compression and wear can create gaps between the pusher rod and the centrifuge drum, allowing material to leak into the equipment and cause corrosion and damage. This shortens the centrifuge's lifespan and increases operating costs. Additionally, the complex structure of the two-stage piston centrifuge means that disassembly for repairs when internal leaks occur is not only inefficient but also cumbersome.

[0004] To address the aforementioned issues, the inventors proposed a two-stage piston pusher centrifuge that can monitor sealing performance in real time during operation. This centrifuge boasts advantages such as automatic sealing detection, automatic alerts when gaps occur, and automatic gap filling. Summary of the Invention

[0005] To achieve the aforementioned objectives of automatically detecting sealing performance, automatically alerting when gaps occur in the machine, and automatically filling gaps, the present invention provides the following technical solution:

[0006] A two-stage piston pusher centrifuge capable of real-time monitoring of sealing performance during operation includes a power unit, a filter tube, and a feed pipe. The filter tube is rotatably connected inside the power unit, and the feed pipe is disposed inside the filter tube. A sealing detection component for detecting the sealing performance of the two-stage piston pusher centrifuge is disposed on the outer wall of the power unit near the filter tube. An alarm component for alerting the user of damage to the two-stage piston pusher centrifuge is disposed on the top of the sealing detection component. A sealing component for sealing the damaged parts of the two-stage piston pusher centrifuge is disposed inside the sealing detection component.

[0007] Furthermore, the sealing detection assembly includes a fixed plate, which is fixedly connected to the outer wall of the power platform near the filter tube. A centrifugal processing tube is fixedly connected to the outer wall of the fixed plate away from the power platform. A spherical groove is formed inside the centrifugal processing tube. A disc plate is fixedly connected to the outer wall of the fixed plate away from the power platform, and the disc plate is disposed inside the centrifugal processing tube. A push rod is slidably connected inside the fixed plate. The end of the push rod away from the centrifugal processing tube is fixedly connected to the inside of the power platform. A hemispherical groove is formed on the outer wall of the push rod. A spherical rod is slidably connected inside the disc plate. A chrome vanadium steel spring is fixedly connected to the top of the disc plate. The end of the chrome vanadium steel spring away from the disc plate is fixedly connected to the spherical rod.

[0008] Furthermore, the alarm assembly includes a windproof box fixedly connected to the top of the centrifugal processing tube. A first fixing rod is fixedly connected to the top of the centrifugal processing tube, and a rotating plate is rotatably connected to the top of the first fixing rod. A second fixing rod is fixedly connected to the top of the centrifugal processing tube, and a triangular rotating disk is rotatably connected to the top of the second fixing rod. A gear disk is fixedly connected to the end of the triangular rotating disk away from the second fixing rod. A positioning block is fixedly connected to the top of the second fixing rod, and a spring-loaded striking rod is rotatably connected inside the positioning block. A metal strip is fixedly connected to the side of the spring-loaded striking rod away from the positioning block. A curved fixing rod is fixedly connected to the outer wall of the second fixing rod, and a metal bell is fixedly connected to the end of the curved fixing rod away from the second fixing rod.

[0009] Furthermore, the sealing assembly includes an elastic ring slidably connected to the interior of a disc plate. The interior of the disc plate has a first groove and a second groove. A limit box is fixedly connected inside the second groove. A positioning hollow tube is fixedly connected inside the limit box. A power slide rod is slidably connected inside the positioning hollow tube. A first spring is fixedly connected to the outer wall of the power slide rod. The end of the first spring away from the power slide rod is fixedly connected to the positioning hollow tube. An L-shaped positioning rod is fixedly connected to the top of the positioning hollow tube. An electromagnet wedge is fixedly connected to the top of the L-shaped positioning rod. A rotating ring is slidably connected to the outer wall of the L-shaped positioning rod. A U-shaped metal rod is fixedly connected to the outer wall of the rotating ring, and the end of the U-shaped metal rod away from the electromagnet wedge is inserted into the interior of the power slide rod. A second spring is fixedly connected to the outer wall of the U-shaped metal rod, and the end of the second spring away from the U-shaped metal rod is fixedly connected to the electromagnet wedge.

[0010] Furthermore, the shape and size of the spherical groove are adapted to the shape and size of the spherical rod, allowing the spherical rod to slide inside the spherical groove.

[0011] Furthermore, the shape and size of the hemispherical groove are adapted to the shape and size of the elastic ring, so that the elastic ring can be snapped into the inside of the hemispherical groove.

[0012] Furthermore, the elastic ring is preferably made of rubber to give it elasticity.

[0013] Furthermore, the elastic striking rod is electrically connected to the power supply of the device, and the electromagnet inclined block is electrically connected to the elastic striking rod, so that the electromagnet inclined block becomes magnetic when in contact with metal.

[0014] Compared with existing technologies and products, the beneficial effects of the present invention are:

[0015] 1. By using the sealing detection component in conjunction with the centrifuge, the sealing performance of the two-stage piston pusher centrifuge can be automatically detected when a sealing problem occurs. At the same time, leakage problems of the centrifuge can be detected in time, avoiding material loss, environmental pollution and other hazards caused by leakage. It also reduces unnecessary energy consumption of the two-stage piston pusher centrifuge, solves the problem of not being able to detect internal leakage problems in time, avoids corrosion and damage to the equipment, extends the service life of the two-stage piston pusher centrifuge, and protects the health and safety of operators.

[0016] 2. By using the alarm components in conjunction with the system, the leakage of the double-stage piston pusher centrifuge is alerted when the metal bell is struck by the elastic striking rod. This reduces the downtime of the centrifuge, avoids unnecessary energy waste, improves production efficiency, solves the problem of not being able to detect leakage faults in the double-stage piston pusher centrifuge, prevents dangerous situations caused by malfunctions of the double-stage piston pusher centrifuge, and solves the problem of manual real-time monitoring of the sealing of the double-stage piston pusher centrifuge, thus reducing maintenance costs.

[0017] 3. Through the coordinated use of sealing components, in the event of a leak in the double-stage piston pusher centrifuge, the power slide rod pushes the elastic ring to fill the leak, reducing material loss and preventing the processed material from spraying out of the machine, thus avoiding environmental pollution. This also improves the safety of the double-stage piston pusher centrifuge, reducing the likelihood of accidents caused by machine malfunctions during leaks. Furthermore, the timely sealing of leaks reduces corrosion and damage to the centrifuge, extending its lifespan. Attached Figure Description

The shape and size of the spherical groove 23 are adapted to the shape and size of the spherical rod 27, so that the spherical rod 27 can slide inside the spherical groove 23.

[0036] The alarm assembly 3 includes a windproof box 31, which is fixedly connected to the top of the centrifugal processing tube 22. A first fixing rod 32 is fixedly connected to the top of the centrifugal processing tube 22. A rotating plate 33 is rotatably connected to the top of the first fixing rod 32.

A gear disk 36 is fixedly connected to the end of the triangular rotating disk 35 away from the second fixing rod 34.

[0037] The sealing assembly 4 includes an elastic ring 41, which is slidably connected to the inside of the disc plate 24. The shape and size of the hemispherical groove 26 are adapted to the shape and size of the elastic ring 41, so that the elastic ring 41 can be snapped into the inside of the hemispherical groove 26. The elastic ring 41 is preferably made of rubber to make it elastic. The inside of the disc plate 24 is provided with a first groove 42 and a second groove 43. A limit box 44 is fixedly connected inside the second groove 43. A positioning hollow tube 45 is fixedly connected inside the limit box 44. A power slide rod 46 is slidably connected inside the positioning hollow tube 45. A first spring 47 is fixedly connected to the outer wall of the power slide rod 46. The end of the first spring 47 away from the power slide rod 46 is connected to the positioning hollow tube 45. An L-shaped positioning rod 48 is fixedly connected to the top of the positioning hollow tube 45. An electromagnet inclined block 49 is fixedly connected to the top of the L-shaped positioning rod 48. A rotating ring 410 is slidably connected to the outer wall of the L-shaped positioning rod 48. A U-shaped metal rod 411 is fixedly connected to the outer wall of the rotating ring 410. The end of the U-shaped metal rod 411 away from the electromagnet inclined block 49 is inserted into the interior of the power slide rod 46. A second spring 412 is fixedly connected to the outer wall of the U-shaped metal rod 411. The end of the second spring 412 away from the U-shaped metal rod 411 is fixedly connected to the electromagnet inclined block 49. The electromagnet inclined block 49 and the elastic striking rod 38 have an electrical connection, so that the electromagnet inclined block 49 becomes magnetic when the elastic striking rod 38 comes into contact with metal.

[0038] Based on the above preferred embodiments, the working principle of the present invention is as follows:

[0039] When not in use: the chrome vanadium steel spring 28 is compressed by the ball rod 27, the second spring 412 is not compressed by the U-shaped metal rod 411 and the electromagnet wedge block 49, and the first spring 47 is compressed by the positioning hollow tube 45 and the power slide rod 46.

[0040] When in use, the operator turns on the power supply to the equipment, the power station 11 starts, and the filter tube 12 begins to rotate at high speed inside the centrifugal processing tube 22. Since the end of the push rod 25 away from the centrifugal processing tube 22 is fixedly connected to the inside of the power station 11, the power station 11 causes the push rod 25 to slide back and forth inside the centrifugal processing tube 22. At this time, the material is sprayed through the feed pipe 13 onto the side of the push rod 25 away from the power station 11. The material slides back and forth inside the centrifugal processing tube 22 with the push rod 25. The material sprayed from the feed pipe 13 gradually accumulates until it is pushed into the inside of the filter tube 12 by the push rod 25. After the material enters the inside of the high-speed rotating filter tube 12, the centrifugal force generated by the high-speed rotation of the filter tube 12 causes the liquid inside the material to be thrown out onto the inner wall of the centrifugal processing tube 22. Due to gravity, the liquid on the inner wall of the centrifugal processing tube 22 gradually gathers at the bottom of the inner cavity of the centrifugal processing tube 22.

[0041] As the push rod 25 reciprocates inside the centrifugal processing tube 22, the side of the push rod 25 near the fixed disk 21 forms a sealed space with the fixed disk 21 inside the disc plate 24. Because the spherical rod 27 is slidably connected inside the disc plate 24, the spherical rod 27 slides within the sealed space formed by the disc plate 24, the push rod 25, and the fixed disk 21. As the push rod 25 moves towards the feed tube 13, the air pressure in this sealed space is lower than the air pressure between the centrifugal processing tube 22 and the disc plate 24, causing the spherical rod 27 to slide inwards into the disc plate 24. When the inside of the disc plate 24 slides away from the feed pipe 13, the air pressure in the sealed space formed by the disc plate 24, the push rod 25, and the fixed plate 21 is close to the air pressure between the centrifugal processing tube 22 and the disc plate 24. At this time, the spherical rod 27 is elastically extended and pushed by the chrome vanadium steel spring 28, causing the spherical rod 27 to slide slightly towards the spherical groove 23 inside the centrifugal processing tube 22. When the spherical rod 27 slides inside the disc plate 24, the chrome vanadium steel spring 28 fixed on the outer wall of the spherical rod 27 is compressed towards the disc plate 24 by the movement of the spherical rod 27. When the push rod 25 slides towards the power table 11, the spherical rod 27 slides slightly towards the inside of the disc plate 24.

[0042] As the push rod 25 slides away from the power table 11, the spherical rod 27 will slide slightly away from the disc plate 24. When leakage occurs in the sealed space formed by the disc plate 24, push rod 25, and fixed plate 21, the sealed space that cannot be formed by the disc plate 24, push rod 25, and fixed plate 21 gradually approaches the air pressure between the centrifugal processing tube 22 and the disc plate 24. Because the chrome vanadium steel spring 28 has strong extensibility, at this time the spherical rod 27 is pushed away from the disc plate 24. The elastic extension push causes the spherical rod 27, which slides inside the disc plate 24, to slide towards the spherical groove 23. This achieves the effect of automatically detecting the sealing performance when the seal of the two-stage piston pusher centrifuge malfunctions. At the same time, it can detect the centrifuge leakage problem in time, avoid the resulting material loss, environmental pollution and other hazards, reduce unnecessary energy consumption of the two-stage piston pusher centrifuge, solve the problem of not being able to detect the leakage problem inside the equipment in time, avoid corrosion and damage to the equipment, extend the service life of the two-stage piston pusher centrifuge, and protect the health and safety of the operators.

[0043] At the end of the elastic extension of the chromium vanadium steel spring 28, the spherical rod 27 passes through the spherical groove 23 and abuts against the rotating plate 33 inside the windproof box 31. Since the rotating plate 33 is rotatably connected to the top of the first fixed rod 32, after the rotating plate 33 is abutted by the spherical rod 27, the end of the rotating plate 33 away from the spherical rod 27 rotates towards the centrifugal processing tube 22. The end of the rotating plate 33 away from the spherical rod 27 abuts against the outer wall of the triangular rotating disk 35, causing the triangular rotating disk 35 to rotate. Since the end of the triangular rotating disk 35 away from the second fixed rod 34 is fixedly connected to the gear disk 36, the gear disk 36 rotates synchronously with the triangular rotating disk 35 as the triangular rotating disk 35 rotates. When the gear disk 36 rotates, due to the metal strip 3... 11 is positioned above the gear disk 36. When the gear disk 36 rotates, it first contacts the end of the metal strip 311 away from the rotating plate 33. Because the metal strip 311 is made of metal and has elasticity, after the end of the metal strip 311 away from the rotating plate 33 is contacted when the gear disk 36 rotates, the metal strip 311 drives the elastic striking rod 38 to rotate in the direction of the metal bell 310 inside the positioning block 37. When the elastic striking rod 38 rotates in the direction of the metal bell 310 at the top of the curved fixing rod 39, the elastic striking rod 38 will strike the metal bell 310 when it rotates.

[0044] After the metal strip 311 contacts the gear disk 36 at one end near the rotating plate 33, the metal strip 311 drives the elastic striking rod 38 to rotate away from the metal bell 310, causing the elastic striking rod 38 to strike the metal bell 310 and produce a sound. This serves as a reminder to the staff that the double-stage piston pusher centrifuge is leaking when the elastic striking rod 38 strikes the metal bell 310, reducing the downtime of the centrifuge, avoiding unnecessary energy waste, improving production efficiency, solving the problem of not being able to detect leaks in the double-stage piston pusher centrifuge, preventing dangerous situations caused by malfunctions of the double-stage piston pusher centrifuge, and solving the problem of manual real-time monitoring of the sealing of the double-stage piston pusher centrifuge, thus reducing maintenance costs.

[0045] When the push rod 25 slides back and forth inside the disc plate 24 for a long time, the outer wall of the push rod 25 will be damaged due to long-term friction with the inner wall of the disc plate 24, which will lead to leakage in the sealed space formed by the push rod 25, the disc plate 24 and the fixed plate 21. Since the elastic striking rod 38 is electrically connected to the power supply of the equipment, and the electromagnet inclined block 49 is electrically connected to the elastic striking rod 38, after the elastic striking rod 38 strikes the metal bell 310, the internal circuit of the electromagnet inclined block 49 is connected. At this time, the electromagnet inclined block 49 becomes magnetic. After the electromagnet inclined block 49 becomes magnetic, it begins to magnetically attract the U-shaped metal rod 411. At this time, the U-shaped metal rod 411, which is fixedly connected to the outer wall of the rotating ring 410, begins to rotate on the outer wall of the L-shaped positioning rod 48. When one end of the U-shaped metal rod 411 touches the electromagnet inclined block 49, the end of the U-shaped metal rod 411 inserted into the power slide rod 46 no longer touches the power slide rod 46.

[0046] At this time, the first spring 47, which is compressed by the positioning hollow tube 45 and the power slide rod 46, extends elastically, causing the power slide rod 46 to slide away from the positioning hollow tube 45. The power slide rod 46 pushes the elastic ring 41 to slide towards the push rod 25. Because the push rod 25 cannot contact the elastic ring 41 when it slides back and forth inside the disc plate 24, the power slide rod 46 pushes the elastic ring 41 to slide towards the push rod 25, causing the elastic ring 41 to move towards the push rod 25. As the push rod 25 slides within the disc plate 24, and the power table 11 causes the push rod 25 to slide towards the limiting box 44, the elastic ring 41, preferably made of rubber, becomes elastic. After being compressed by the outer wall of the push rod 25, the elastic ring 41 begins to deform. When the hemispherical groove 26 on the outer wall of the push rod 25 contacts the elastic ring 41, the shape and size of the hemispherical groove 26 are compatible with the shape and size of the elastic ring 41. This allows the elastic ring 41 to engage inside the hemispherical groove 26. When the power table 11 causes the push rod 25 to slide back and forth inside the disc plate 24, the disc plate 24, push rod 25, and fixed disc 21 form a sealed space again. This achieves the goal of filling the gap in the double-stage piston pusher centrifuge by pushing the elastic ring 41 with the power slide rod 46 after a leak occurs, reducing material loss and preventing the processed material from spraying out of the machine, thus avoiding pollution of the processed material environment. It also improves the safety of the double-stage piston pusher centrifuge, reducing the risk of accidents caused by machine malfunctions when a leak occurs. Furthermore, timely sealing of leaks reduces corrosion and damage to the centrifuge, extending its lifespan.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
