Description

Technical Field

[0001] The present invention relates to the technical field of valve housing processing, and particularly to a steam turbine valve housing processing device. Background Art

[0002] As the core component of the steam turbine steam inlet system, the steam turbine valve housing is usually made of high-strength heat-resistant steel or stainless steel through sand casting or investment casting processes. Its internal flow path is complex and the dimensional accuracy requirements are high. Since the steam turbine valve housing is made by casting process, after the valve housing is manufactured, its inner wall is relatively rough and the inner wall of the valve housing needs to be bored.

[0003] For example, a steam turbine valve housing processing device described in Patent No. CN118023575B uses a limiting mechanism to limit and fix the valve housing horizontally and a supporting mechanism to limit and fix the valve housing vertically, so that the valve housing is fixed more firmly on the turntable. When the turntable rotates, a counterweight balances the turntable, enabling the turntable to rotate stably, thereby improving the boring processing accuracy of the inner wall of the valve housing. However, when processing the valve housing with this processing device, the generated waste is not processed. The waste generated from the valve housing processing has significant utilization value, and its metal material can be recycled through processes such as crushing, sorting, and melting, and remade into metal ingots or alloy materials for producing new parts. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a steam turbine valve housing processing device.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A steam turbine valve housing processing device includes a base, a box body, and a pushing wheel. A solid-liquid separation component is provided inside the box body, and the solid-liquid separation component is used to separate the cutting fluid from the waste generated during processing. An extrusion component is also provided inside the box body, and the extrusion component is used to extrude the waste separated by the solid-liquid separation component to further extrude the residual cutting fluid in the waste.

[0007] The solid-liquid separation component includes a driving mechanism and a separation mechanism. A worm and a worm gear are provided inside the driving mechanism. The separation mechanism consists of a conveying part and a separation part. A spiral blade is provided inside the conveying part, and a filter cylinder is provided inside the separation part. The worm and the worm gear mesh, and the worm gear is fixedly connected to the conveying part through a rotating shaft. The worm drives the worm gear to rotate, thereby driving the conveying part to rotate, so as to convey the waste spirally downward through the spiral blade. At the same time, the liquid is separated from the waste through the filter cylinder under the centrifugal force of the rotating spiral blade.

[0008] Preferably, the extrusion assembly is composed of a transmission mechanism and an extrusion mechanism. A reciprocating lead screw and a nut are provided in the transmission mechanism. The extrusion mechanism is composed of a set of smooth parts and a sliding part. A slider, a first spring, and an extrusion plate are provided in the smooth part. An inclined plane slider and a second spring are provided in the sliding part. A first mounting plate and a second mounting plate are installed at the lower end of the base. A first push rod is provided on the first mounting plate. A second pressing block is fixedly connected to the end of the first push rod away from the first mounting plate. When the reciprocating lead screw rotates, it drives the nut to slide forward, thereby driving the extrusion mechanism to slide. When the extrusion mechanism slides, the second pressing block pushes the inclined plane slider to slide down, thereby driving the entire sliding part to compress the second spring downward. At this time, the smooth part rebounds through the first spring, thereby driving the extrusion plate to rebound and extrude.

[0009] Preferably, a knocking assembly is provided in the box body. The knocking assembly is used to knock the surface of the second mounting plate. The knocking assembly is composed of another set of smooth parts, a sliding part, and a knocking part. The knocking part is fixedly connected to the side wall of the smooth part. A third electric push rod is installed on the first mounting plate. The telescopic end of the third electric push rod is fixedly connected to a third pressing block. When the reciprocating lead screw rotates, it drives the nut to slide forward, thereby driving the knocking assembly to slide. When the knocking assembly slides, the third electric push rod pushes out the third pressing block, pushing the inclined plane slider to slide down, thereby driving the entire sliding part to compress the second spring downward. At this time, the smooth part rebounds through the first spring, driving the knocking part to knock the surface of the second mounting plate.

[0010] Preferably, a chute bracket, a fixed box, a through groove, and a support body are installed on the base. A chute, a slide plate, a first electric push rod, and a second electric push rod are provided on the chute bracket. A valve housing is provided in the fixed box. The support body is arranged in the through groove. The valve housing is placed on the support body. A boring component and a liquid spraying component are installed at the lower end of the slide plate. The telescopic end of the second electric push rod is fixedly connected to a first pressing block. The second electric push rod can fix both ends of the valve housing by pushing the first pressing block downward. The first electric push rod pushes the slide plate downward, thereby driving the boring component and the liquid spraying component to slide downward.

[0011] Preferably, when the boring component slides downward, it can perform boring processing on the valve housing. The liquid spraying component slides downward synchronously and sprays cutting fluid, flushing the waste materials processed by boring into the through groove.

[0012] Preferably, a first guide rod and a second guide rod are provided between the first mounting plate and the second mounting plate. The nut slides on the first guide rod. The extrusion assembly and the knocking assembly slide on the second guide rod.

[0013] Preferably, a collection box is provided inside the box body. A filter plate is provided inside the collection box. When the extrusion plate rebounds and extrudes the waste materials in the collection box, the residual liquid in the waste materials can be extruded, and the extruded liquid falls to the lower part of the collection box through the filter plate.

[0014] Preferably, a solid-liquid separation box is provided inside the separation part. The solid-liquid separation box is fixedly connected to the inner wall of the box body through a third mounting plate. The upper end of the rotating shaft is fixedly connected with a top plate. A second motor is provided inside the driving mechanism. A fourth mounting plate is fixedly connected to the side wall of the first mounting plate. The second motor is mounted on the fourth mounting plate. Two sets of solid-liquid separation components, extrusion components, and knocking components are provided.

[0015] The present invention has the following beneficial effects:

[0016] 1. In the present invention, when the boring component processes the valve housing downward, the liquid spraying component is started simultaneously to spray the cutting fluid. When the boring component works, it can cool the tool bit, and at the same time, the waste materials from the boring process are flushed into the leakage pipe through the through groove. The cutting fluid mixed with the waste materials flushes into the solid-liquid separation box. The worm drives the worm wheel to rotate, and then drives the conveying part to rotate, so as to convey the waste materials downward in a spiral manner through the spiral blade. At the same time, the cutting fluid is separated from the waste materials through the filter cylinder under the action of the centrifugal force generated by the rotation of the spiral blade.

[0017] 2. Further, when the second motor is started, the reciprocating lead screw rotates. When the reciprocating lead screw rotates, it drives the nut to slide forward, and then drives the extrusion mechanism to slide. When the extrusion mechanism slides, the second pressing block pushes the inclined plane slider to slide downward, and then drives the entire sliding part to compress the second spring downward. At this time, the smooth part rebounds through the first spring, and then drives the extrusion plate to rebound and extrude the waste materials in the collection box. The extruded liquid falls to the lower part of the collection box through the filter plate.

[0018] 3. Further, when there is too much waste material in the collection box and the pressure sensor senses a certain pressure, when the reciprocating lead screw rotates to drive the nut to slide forward and then drives the knocking component to slide, the third electric push rod pushes out the third pressing block, pushes the inclined plane slider to slide downward, and then drives the entire sliding part to compress the second spring downward. At this time, the smooth part rebounds through the first spring, driving the knocking part to knock on the surface of the second mounting plate to remind the staff that the collection box is full.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Embodiment 1:

[0031] Refer to Figures 1 - 7 and Figure 9, A steam turbine valve housing processing device, including a base 1, a box body 2, and a pushing wheel 3. A solid-liquid separation component is provided inside the box body 2, and the solid-liquid separation component is used to separate the cutting fluid from the waste generated during processing. An extrusion component is also provided inside the box body 2, and the extrusion component is used to extrude the waste separated by the solid-liquid separation component to further extrude the residual cutting fluid in the waste.

[0032] The solid-liquid separation component includes a driving mechanism and a separation mechanism. A worm 34 and a worm gear 33 are provided inside the driving mechanism. The separation mechanism consists of a conveying part and a separation part. A spiral blade 25 is provided inside the conveying part, and a filter cylinder 26 is provided inside the separation part. The worm 34 and the worm gear 33 are meshed, and the worm gear 33 is fixedly connected to the conveying part through a rotating shaft 24. The worm 34 drives the worm gear 33 to rotate, thereby driving the conveying part to rotate, so as to convey the waste spirally downward through the spiral blade 25. At the same time, the liquid is separated from the waste through the filter cylinder 26 under the action of the centrifugal force generated by the rotation of the spiral blade 25.

[0033] A chute bracket 4, a fixed box 7, a through groove 17, and a support body 18 are installed on the base 1.

A boring component and a liquid spraying component are installed at the lower end of the sliding plate 6. The telescopic end of the second electric push rod 10 is fixedly connected with a first pressing block 11. When the second electric push rod 10 pushes the first pressing block 11 downward, the two ends of the valve housing 8 can be fixed. The first electric push rod 9 pushes the sliding plate 6 downward, thereby driving the boring component and the liquid spraying component to slide downward.

[0034] When the boring component slides downward, it can perform boring processing on the valve housing 8. The liquid spraying component slides downward synchronously and sprays cutting fluid to flush the waste produced by the boring processing into the through groove 17.

[0035] A collection box 49 is provided inside the box body 2. A filter plate 52 is provided inside the collection box 49. When the extrusion plate 50 rebounds and extrudes the waste inside the collection box 49, the residual liquid in the waste can be extruded, and the extruded liquid falls to the lower part of the collection box 49 through the filter plate 52.

[0036] A solid-liquid separation box 22 is provided inside the separation part. The solid-liquid separation box 22 is fixedly connected to the inner wall of the box body 2 through a third mounting plate 58. The upper end of the rotating shaft 24 is fixedly connected with a top plate 23. A second motor 31 is provided inside the driving mechanism.

[0037] In this embodiment, the driving mechanism can specifically adopt the following structure:

[0038] The driving mechanism consists of a second motor 31, a worm 34, and a worm gear 33. The output shaft of the second motor 31 is fixedly connected to the worm 34, and the worm gear 33 is fixedly connected to the rotating shaft 24.

[0039] The separating mechanism can specifically adopt the following structure:

[0040] The separating mechanism includes a conveying part and a separating part. The conveying part consists of a first solenoid valve 28, a leakage pipe 19, a third liquid outlet pipe 21, a spiral blade 25, a second solenoid valve 29, and a discharge pipe 30. The separating part consists of a filter cartridge 26, a solid-liquid separation box 22, and a fourth liquid outlet pipe 53. The upper feed port of the leakage pipe 19 is fixedly connected to the circular outlet of the support body 18. The lower outlet of the leakage pipe 19 is fixedly connected to the first solenoid valve 28. The first solenoid valve 28 is fixedly connected to the upper end of the third liquid outlet pipe 21. The lower end of the third liquid outlet pipe 21 is fixedly connected to the upper end of the solid-liquid separation box 22 near the center of the rotating shaft 24. The side wall of the rotating shaft 24 is fixedly connected with a spiral blade 25. The filter cartridge 26 is fixedly connected to the inside of the solid-liquid separation box 22 close to the outer periphery of the spiral blade. The lower outlet of the solid-liquid separation box 22 is provided with a second solenoid valve 29, and the second solenoid valve 29 is fixedly connected to the discharge pipe 30. The lower end of the discharge pipe 30 is fixedly connected to the upper end of the collection box 49. One end of the fourth liquid outlet pipe 53 is fixedly connected to the side wall of the lower end of the solid-liquid separation box 22.

[0041] The boring component can specifically adopt the following structure:

[0042] The boring component consists of a first motor 12 and a cutter head 13. The first motor 12 is fixedly connected to the cutter head 13.

[0043] The liquid spraying component can specifically adopt the following structure:

[0044] The liquid spraying component consists of a spray head 16, a first liquid outlet pipe 54, a second liquid outlet pipe 15, a water pump 14, and a liquid storage tank 57. The inlet of the water pump 14 is fixedly connected to the liquid storage tank 57 through the first liquid outlet pipe 54. The outlet of the water pump is fixedly connected to the second liquid outlet pipe 15. The other end of the second liquid outlet pipe 15 is fixedly connected to the spray head 16. The spray head 16 is fixedly connected to the slide plate 6. The other end of the fourth liquid outlet pipe 53 is fixedly connected to the liquid storage tank 57.

[0045] In this embodiment, when machining the inner wall of the valve housing 8, the second electric push rod 10 pushes the first pressing block 11 downward to fix both ends of the valve housing 8. The first electric push rod 9 pushes the slide plate 6 downward, thereby driving the first motor 12 and the cutter head 13 to move downward to machine the inner wall of the valve housing 8. At the same time, the water pump 14 is started to pump the cutting fluid in the liquid storage tank 57 through the first liquid outlet pipe 54 and the second liquid outlet pipe 15 and spray it out from the spray head 16 to lubricate and cool the cutter head 13.

[0046] The waste produced by the mixing of cutting fluid enters the solid-liquid separation tank 22 through the through groove 17, the leakage pipe 19, and the third liquid outlet pipe 21. The second motor 31 is started to drive the worm 34 and the worm gear 33 to rotate, and then drive the rotating shaft 24 and the spiral blade 25 to rotate. The waste is spirally conveyed downward by the spiral blade 25. At the same time, the cutting fluid is separated from the waste through the filter cylinder 26 under the action of the centrifugal force of the rotating spiral blade 25 and enters the liquid storage tank 57 through the fourth liquid outlet pipe 53, so that the cutting fluid can be recycled to a certain extent.

[0047] It should be noted that two sets of solid-liquid separation components are provided. During actual operation, the two sets of components can be used alternately. When one set of solid-liquid separation components is used for too long and too much waste accumulates at the upper end of the second solenoid valve 29, the first solenoid valve 28 in this set of solid-liquid separation components that is in use can be closed, and the cutting fluid in the corresponding solid-liquid separation tank 22 is completely discharged through the fourth liquid outlet pipe 53. At this time, the second solenoid valve 29 is opened to discharge the waste at the lower end of the spiral blade 25 through the discharge pipe 30 into the collection box 49, while the other set of solid-liquid separation components can work normally and will be alternated with the first set of solid-liquid separation components later.

[0048] Embodiment 2:

[0049] Refer to Figures 3 - 5 and Figure 8 The extrusion assembly is composed of a transmission mechanism and an extrusion mechanism. The transmission mechanism is provided with a reciprocating lead screw 32 and a nut 35. The extrusion mechanism is composed of a set of smooth parts and a sliding part. The smooth part is provided with a slider 20, a first spring 41, and an extrusion plate 50. The sliding part is provided with an inclined plane slider 38 and a second spring 40. A first mounting plate 55 and a second mounting plate 56 are installed at the lower end of the base 1. A first push rod 42 is provided on the first mounting plate 55. One end of the first push rod 42 away from the first mounting plate 55 is fixedly connected with a second pressing block 43. When the reciprocating lead screw 32 rotates, it drives the nut 35 to slide forward, and then drives the extrusion mechanism to slide. When the extrusion mechanism slides, the second pressing block 43 pushes the inclined plane slider 38 to slide down, thereby driving the entire sliding part to compress the second spring 40 downward. At this time, the smooth part rebounds through the first spring 41, and then drives the extrusion plate 50 to rebound and extrude.

[0050] A first guide rod 36 and a second guide rod 37 are provided between the first mounting plate 55 and the second mounting plate 56. The nut 35 slides on the first guide rod 36, and the extrusion assembly and the knocking assembly slide on the second guide rod 37.

[0051] Combined with Embodiment 1, the transmission mechanism of this embodiment can specifically adopt the following structure:

[0052] The transmission mechanism is composed of a reciprocating lead screw 32 and a nut 35. The reciprocating lead screw 32 is slidably connected with the nut 35, and the reciprocating lead screw 32 is coaxially fixedly connected with the worm 34.

[0053] The extrusion mechanism includes a set of smooth parts and sliding parts. The smooth parts are composed of a slider 20, a first spring 41, and a slider box 60. The sliding parts are composed of an inclined plane slider 38, a slide bar 39, a second spring 40, a connecting rod 48, and an extrusion plate 50. The slider 20 slides on the second guide rod 37. The slider 20 is fixedly connected to the second mounting plate 56 through the first spring 41. The side wall of the slider 20 is fixedly connected to the slider box 60. The inclined plane slider 38 slides in the slider box 60. One end of the second spring 40 is fixedly connected to the lower end of the inclined plane slider 38, and the other end is fixedly connected to the lower end of the slider box 60. The slide bar 39 is fixedly connected to the lower end of the inclined plane slider 38 and is slidably connected through the lower end of the slider box 60. The extrusion plate 50 is fixedly connected to the lower end of the slider box 60 through the connecting rod 48. The connecting rod 48 penetrates the side wall of the collection box 49. The extrusion plate 50 slides on the filter plate 52.

[0054] In the first embodiment, when the motor starts to drive the worm 34 to rotate, the reciprocating lead screw 32 rotates simultaneously. In this embodiment, when the reciprocating lead screw 32 rotates, it drives the nut 35 to slide forward. When the nut 35 slides, its inclined surface part can drive the inclined plane slider 38 to slide, thereby driving the slider 20 and the slider box 60 to slide together. When the inclined plane slider 38 slides to the second pressing block 43, the second pressing block 43 pushes the inclined plane slider 38 to slide downward, thereby driving the slide bar 39 to slide downward and compressing the second spring 40 downward. At this time, the nut 35 no longer drives the inclined plane slider 38 to slide, while the slider 20 and the slider box 60 rebound through the first spring 41, thereby driving the connecting rod 48 and the extrusion plate 50 to rebound and extrude the waste materials in the collection box 49.

[0055] It should be noted that the rotation of the reciprocating lead screw 32 can drive the nut 35 to reciprocate, so that the extrusion plate 50 can reciprocally extrude the waste materials in the collection box 49. At the same time, when the collection box 49 gradually receives more waste materials, the setting of the first spring 41 can buffer the extrusion movement of the extrusion plate 50.

[0056] Embodiment Three:

[0057] Referring to Figure 4 , a knocking component is provided in the box body 2. The knocking component is used to knock the surface of the second mounting plate 56. The knocking component is composed of another set of smooth parts, sliding parts, and knocking parts. The knocking part is fixedly connected to the side wall of the smooth part. A third electric push rod 44 is installed on the first mounting plate 55. The telescopic end of the third electric push rod 44 is fixedly connected with a third pressing block 45. When the reciprocating lead screw 32 rotates, it drives the nut 35 to slide forward, thereby driving the knocking component to slide. When the knocking component slides, the third electric push rod 44 pushes out the third pressing block 45, pushing the inclined plane slider 38 to slide downward, thereby driving the entire sliding part to compress the second spring 40 downward. At this time, the smooth part rebounds through the first spring 41, driving the knocking part to knock the surface of the second mounting plate 56.

[0058] The knocking component can specifically adopt the following structure:

[0059] The knocking component is composed of another set of smooth part, sliding-down part and knocking part. The smooth part is composed of a slider 20, a first spring 41 and a slider box 60. The sliding-down part is composed of an inclined-plane slider 38, a slide bar 39, a second spring 40, a connecting rod 48 and a pressing plate 50. The knocking part is composed of a pressure sensor 51, a second push rod 46 and a fourth pressing block 47. The slider 20 slides on the second guide rod 37. The slider 20 is fixedly connected to the second mounting plate 56 through the first spring 41. The side wall of the slider 20 is fixedly connected to the slider box 60. The inclined-plane slider 38 slides in the slider box 60. One end of the second spring 40 is fixedly connected to the lower end of the inclined-plane slider 38, and the other end is fixedly connected to the lower end of the slider box 60. The slide bar 39 is fixedly connected to the lower end of the inclined-plane slider 38 and is slidably connected through the lower end of the slider box 60. The pressure sensor 51 is fixedly connected above the filter plate 52 and is electrically connected to the third electric push rod 44. The second push rod 46 is fixedly connected to the fourth pressing block 47. The other end of the second push rod 46 is fixedly connected to the side wall of the slider 20.

[0060] In this embodiment, in combination with Embodiments 1 and 2, when there is too much waste in the collection box 49, the pressure sensor 51 senses a certain pressure, and the third electric push rod 44 is started. The reciprocating lead screw 32 rotates to drive the nut 35 to slide forward. When the nut 35 slides, its inclined surface drives the inclined-plane slider 38 to slide, and then drives the slider 20 and the slider box 60 to slide together. When the third electric push rod 44 is started, the third pressing block 45 can be pushed out. Then, the third pressing block 45 can push the inclined-plane slider 38 to slide down, thereby driving the slide bar 39 to slide downward and compressing the second spring 40 downward. At this time, the nut 35 no longer drives the inclined-plane slider 38 to slide, while the slider 20 and the slider box 60 rebound through the first spring 41, driving the second push rod 46 and the fourth pressing block 47 to rebound. When the fourth pressing block 47 rebounds, it can knock on the surface of the second mounting plate 56 to remind the staff that the collection box 49 is full and the waste in the box should be removed in time.

[0061] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
