Description

Technical Field

[0001] This utility model belongs to the field of potato processing technology, and in particular relates to a steam exhaust device for potato peeling equipment. Background Technology

[0002] Potato peeling equipment is a type of machinery specifically designed to remove the outer skin of potatoes. It aims to improve peeling efficiency, reduce labor costs, and ensure consistent and high-quality peeling results. The main type of potato peeling machine is the steam peeler. This type of equipment uses high-pressure, high-temperature saturated steam to evenly heat the potatoes and then instantly releases the pressure to separate the skin from the flesh.

[0003] When potato peeling equipment scalds potatoes with steam, the process involves intermittent steam intake and exhaust. The steam needs to be expelled quickly, so a booster pump is typically installed in the exhaust pipe to rapidly extract the steam. Therefore, the steam discharged after peeling contains potato peels, mud, and other impurities. If these impurities are not treated, they can cause blockages in the pipes and booster pump during steam recovery, leading to equipment malfunction.

[0004] In existing technologies, separators are mostly used to separate impurities from exhaust gas. However, when separating impurities with a separator, it is necessary to clean the separator regularly to avoid clogging caused by prolonged use. Furthermore, when cleaning the separator, the equipment must be turned off, which leads to a decrease in potato peeling efficiency.

[0005] Therefore, in the existing potato peeling equipment, when treating waste gas, there is a problem that the separator becomes clogged after prolonged use, requiring staff to shut down the equipment and clean the separator, thus reducing the potato peeling efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the existing potato peeling equipment that, during waste gas treatment, causes the separator to become clogged after prolonged use, requiring staff to shut down the equipment and clean the separator, thus reducing the potato peeling efficiency.

[0007] To address the aforementioned problems, this utility model provides a steam exhaust device for a potato peeling machine, comprising an exhaust pipe, a filter assembly, and a cleaning assembly. One end of the exhaust pipe is connected to the steam outlet of the potato peeling machine, and the other end is connected to the steam inlet of a heat exchange device. The exhaust pipe has an outlet, a passage, and a pressure relief port on its side wall. The outlet and passage are positioned opposite each other relative to the axis of the exhaust pipe. The pressure relief port is located on the side wall of the exhaust pipe, near the upstream side, relative to the outlet and passage in the steam flow direction. The filter assembly includes a filter element and an opening / closing element. The filter element is disposed within the exhaust pipe, located downstream of the outlet in the steam flow direction, and its peripheral wall is fitted to the inner wall of the exhaust pipe. The opening / closing element is adaptably detachable within the outlet.

[0008] Furthermore, the cleaning component is disposed on the outer wall of the exhaust pipe, on the opposite side of the exhaust pipe circumferentially relative to the opening and closing component. The cleaning component includes a cleaning component that is adapted to the through port and can be moved radially along the exhaust pipe and extend into the exhaust pipe through the through port.

[0009] Furthermore, in the axial direction of the exhaust pipe, the end face of the filter element near the outlet, the downstream edge of the outlet, and the bottom wall of the cleaning element are aligned with each other; and the cleaning element moves in the radial direction of the exhaust pipe, with its bottom wall adhering to the filter element to clean the filter element.

[0010] Using the above technical solution, after this exhaust device is installed on the potato peeling equipment, when the equipment is working, the steam from scalding the potatoes inside the peeling machine is discharged from the steam outlet and enters the exhaust pipe. The discharged steam is then filtered by a filter component installed within the exhaust pipe, thus removing impurities from the exhaust steam. When the filter component becomes clogged, the pressure in the exhaust pipe rises to a certain threshold (e.g., above 2.0 MPa), and steam flows out from the pressure relief port, preventing it from flowing back into the potato peeling equipment and ensuring its reliability. Furthermore, when the pressure relief component is opened, the operator can push the cleaning component radially along the exhaust pipe to clean the filter component. This method of cleaning the filter component eliminates the need to shut down the potato peeling equipment for filtration and cleaning, ensuring the potato peeling efficiency of the equipment.

[0011] According to an embodiment of the present invention, a steam exhaust device for a potato peeling equipment includes a cleaning component comprising a pressure relief component disposed on an openable pressure relief port and a driving component disposed between the pressure relief component and the cleaning component. The driving component comprises a rotating component and a driving member disposed between the rotating component and the cleaning component. The rotating component is disposed outside the pressure relief port and directly opposite the pressure relief component. The end of the rotating shaft of the driving component near the pressure relief port is fixedly connected to the rotating component, and the other end of the rotating shaft away from the pressure relief port is connected to the cleaning component via the driving member. The rotating component is connected to the cleaning component via the driving member.

[0012] Furthermore, the rotating component rotates in conjunction with the driving component, which in turn moves the cleaning component along the passage relative to the filter component to clean the filter component.

[0013] Using the above technical solution, when the potato peeling equipment is working, the steam from the scalded potatoes inside the potato peeling machine is discharged from the steam outlet of the potato peeling machine into the exhaust pipe, and continuously flows from the exhaust pipe to the heat exchange device; at the same time, the steam passing through the exhaust pipe is filtered by the filter components, so that the steam entering the heat exchange device remains clean and avoids the impact of impurities on the subsequent steam reuse.

[0014] Furthermore, when impurities clog the filter components and the air pressure in the exhaust pipe rises to a certain threshold (e.g., above 2.0 MPa), the pressure relief component opens, and steam flows out from the pressure relief port. The flowing steam blows the rotating component and drives the cleaning component to move relative to the filter components along the passage to clean the filter components. In addition, during the process of cleaning the filter components by moving relative to the filter components along the passage, the cleaning component can push open the opening and closing component, and push the impurities attached to or deposited on the filter components out of the exhaust port into the external space, thereby ensuring that the impurities on the filter components can be cleaned in a timely manner.

[0015] According to the embodiments of the present invention, the exhaust device for potato peeling equipment includes a drive component that further includes an exhaust pipe, wherein one end of the exhaust pipe surrounds the pressure relief port and is fixedly connected to the outer wall of the exhaust pipe, and the other end is connected to the external space; a rotating component is sleeved on a rotating shaft and located inside the exhaust pipe opposite to the pressure relief port; the rotating shaft extends parallel to the exhaust pipe, one end is rotatably connected to the inner wall of the exhaust pipe on the side away from the cleaning component, and the other end extends into the cleaning component and is connected to the drive component.

[0016] By adopting the above technical solution, when impurities clog the filter components and the air pressure in the exhaust pipe rises to a certain threshold (such as above 2.0 MPa), the pressure relief component opens, and steam flows out of the exhaust pipe from the pressure relief port into the vent pipe. The vent pipe collects the steam flowing out of the exhaust pipe, thereby increasing the blowing force of the steam on the rotating component, which in turn increases the driving force of the steam on the rotating component. This ensures that the rotating component can rotate reliably and drive the cleaning component to move and clean the filter components.

[0017] According to the embodiments of the present invention, the exhaust device for potato peeling equipment includes a rotating component further comprising multiple rotating blades, and a driving component configured as a rotating gear; wherein, the multiple rotating blades are fixed at intervals along the circumference of the rotating shaft to the circumferential side wall of the rotating shaft, and the multiple rotating blades are all inclined at a certain angle toward the same side of the exhaust pipe; the rotating gear is fixedly connected to the other end of the rotating shaft and is connected in transmission with the cleaning component.

[0018] By adopting the above technical solution, since multiple rotating blades are tilted at a certain angle toward the same side of the venting pipe, when the pressure relief component is opened, steam flows out of the venting pipe from the pressure relief port into the venting pipe, ensuring that the steam drives multiple blades to rotate the shaft in the same direction, reliably driving the rotating gear to rotate and drive the cleaning component to clean the filter component.

[0019] According to an embodiment of the present invention, the exhaust device for a potato peeling equipment includes a cleaning component comprising a limiting component, a transmission component, and a cleaning component arranged sequentially along the width of the exhaust pipe; wherein, one end of the transmission component is fixedly connected to one end of the cleaning component, and the other end is fixedly connected to the limiting component, and the other end of the cleaning component extends at least partially into the passage; and a rotating gear is connected to the transmission component in a transmission manner.

[0020] By adopting the above technical solution, the power from the drive component can be transmitted to the cleaning component by setting the transmission component and the rotating gear transmission connection. The cleaning component can clean the filter component by setting the cleaning component. The limiting component can limit the displacement of the transmission component and prevent the rotating gear from disengaging from the transmission component due to excessive displacement distance.

[0021] According to the embodiments of this utility model, the exhaust device for potato peeling equipment also includes a support shell, a connection port on the support shell, and the support shell is fixedly installed on the outer wall of the exhaust pipe. The driving component and the cleaning component are both located inside the support shell, and the other end of the exhaust pipe extends into the connection port and communicates with the external space.

[0022] By adopting the above technical solution, the drive component and the cleaning component can be protected and supported by the supporting shell, thus avoiding the risk of damage to the drive component and the cleaning component due to operator error during transportation or installation of the exhaust device.

[0023] According to an embodiment of this utility model, the exhaust device for a potato peeling equipment includes an opening and closing component comprising a "T"-shaped plate and a pair of springs. A pair of mounting holes are provided on the periphery of the exhaust port. The pair of springs and the pair of mounting holes correspond to and are adapted to each other. One end of the pair of springs is disposed on the side of the wing plate of the "T"-shaped plate near the exhaust pipe, relative to the web of the "T"-shaped plate. The other end extends into the pair of mounting holes and is fixedly connected to the side wall of the wing plate away from the "T"-shaped plate. The web of the "T"-shaped plate extends into the exhaust port and is adapted to the exhaust port.

[0024] Using the above technical solution, when the cleaning component moves to clean the filter component, the cleaning component can push the web of the "T"-shaped plate to push the impurities out of the outlet and discharge them into the external space; when the cleaning component completely pushes the impurities out of the outlet and retracts relative to the outlet, the web of the "T"-shaped plate can close the outlet again under the action of the spring's rebound force.

[0025] The exhaust device for potato peeling equipment provided according to the embodiments of this utility model further includes a negative pressure pump, which is disposed between the exhaust device and the heat exchange device and is connected to the pipelines of the exhaust device and the heat exchange device respectively.

[0026] Using the above technical solution, when scalding potatoes with a potato peeler, the steam generated by the potato peeler is relatively fast, so the steam needs to be discharged quickly. By setting a negative pressure pump, the steam discharge speed can be increased, thereby improving the scalding rate of potatoes.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model discloses a steam exhaust device for a potato peeling machine, comprising: an exhaust pipe, a filter assembly, and a cleaning assembly; one end of the exhaust pipe is connected to the steam outlet of the potato peeling machine, and the other end is connected to the steam inlet of a heat exchange device; the exhaust pipe has an outlet, a passage, and a pressure relief port on its side wall, the outlet and the passage are arranged opposite to each other relative to the axis of the exhaust pipe, and the pressure relief port is located on the side wall of the exhaust pipe near the upstream side relative to the outlet and the passage in the steam flow direction; the filter assembly includes a filter element and an opening / closing element, the filter element is disposed in the exhaust pipe, located downstream of the outlet in the steam flow direction, and its peripheral wall is fitted and connected to the inner wall of the exhaust pipe, and the opening / closing element is adaptable to the outlet.

[0029] Furthermore, the cleaning component is disposed on the outer wall of the exhaust pipe, on the opposite side of the exhaust pipe circumferentially relative to the opening and closing component. The cleaning component includes a cleaning component that is adapted to the through port and can be moved radially along the exhaust pipe and extend into the exhaust pipe through the through port.

[0030] Furthermore, after this exhaust device is installed on the potato peeling equipment, during operation, the steam from scalding the potatoes inside the peeling machine is discharged from the steam outlet and enters the exhaust pipe. The discharged steam is then filtered by a filter component installed within the exhaust pipe, thus removing impurities from the exhaust steam. When the filter component becomes clogged, the pressure in the exhaust pipe rises to a certain threshold (e.g., above 2.0 MPa), causing the pressure relief component to open. Steam flows out from the pressure relief port and does not flow back into the potato peeling equipment, ensuring the reliability of the equipment's operation. Additionally, when the pressure relief component is open, the operator can push the cleaning component along the width of the exhaust pipe to clean the filter component. This method of cleaning the filter component eliminates the need to shut down the potato peeling equipment, ensuring the efficient peeling of potatoes. Attached Figure Description

[0050] When potato peeling equipment scalds potatoes with steam, the steam intake and exhaust process is intermittent, requiring rapid steam removal. Typically, a booster pump is installed in the exhaust pipe to quickly extract the steam from the peeling equipment. However, during this extraction process, because the potatoes have already been scalded, the skin and flesh have separated. Therefore, the steam carries some potato peel, dirt, and other impurities with it. If these impurities are not treated, they can cause blockages in the pipes and booster pump during steam recovery, leading to equipment malfunction.

[0051] In existing technologies, separators are mostly used to separate impurities from exhaust gas. However, when separating impurities with a separator, it is necessary to clean the separator regularly to avoid clogging caused by prolonged use. Furthermore, when cleaning the separator, the equipment must be turned off, which leads to a decrease in potato peeling efficiency.

[0052] To address the aforementioned problems, this utility model provides a steam exhaust device for potato peeling equipment. When installed on the potato peeling equipment, the steam from scalding the potatoes inside the peeling machine is discharged from the steam outlet and enters the exhaust pipe. The discharged steam is then filtered by a filter component installed within the exhaust pipe, removing impurities. When the filter component becomes clogged, the pressure in the exhaust pipe rises to a certain threshold (e.g., above 2.0 MPa), causing steam to flow out from the pressure relief port. The steam does not flow back into the potato peeling equipment, ensuring its reliability. Furthermore, when the pressure relief component is open, the operator can push a cleaning component along the width of the exhaust pipe to clean the filter component. This method of cleaning the filter component eliminates the need to shut down the potato peeling equipment, ensuring the efficient peeling of potatoes.

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0054] First, a general description of the exhaust device used in potato peeling equipment will be given.

[0055] like Figure 1 As shown in the figure, this utility model embodiment discloses a steam exhaust device for potato peeling equipment, including: a steam exhaust pipe 1, a filter assembly 2, a cleaning assembly 3, and a negative pressure pump 6.

[0056] Specifically, one end of the exhaust pipe 1 is connected to the steam outlet of the potato peeler 5, and the other end is connected to the steam inlet of the heat exchange device 7. The steam from scalding the potatoes in the potato peeler 5 flows into the exhaust pipe 1 through its steam outlet, and then into the heat exchange device 7. Furthermore, the side wall of the exhaust pipe 1 is provided with an outlet 10, a passage 11, and a pressure relief port 12. The outlet 10 and the passage 11 are positioned opposite each other relative to the axis of the exhaust pipe 1, and the pressure relief port 12 is located on the side wall of the exhaust pipe 1, near the upstream side, relative to the outlet 10 and the passage 11 in the steam flow direction.

[0057] It should be understood that the structure and setting of the potato peeling machine 5 are not limited. For example, it can be a potato steam peeling machine. This embodiment does not limit it. The structure and setting of the heat exchange device 7 are not limited. For example, it can be a heat exchange pool, a heat exchanger, etc., as long as it can condense the steam discharged from the potato peeling machine 5 into condensate. This embodiment does not limit it.

[0058] More specifically, the filter assembly 2 includes a filter element 20 and an opening / closing element 21. The filter element 20 is disposed inside the exhaust pipe 1, downstream of the outlet 10 in the steam flow direction, and its peripheral wall is attached to the inner wall of the exhaust pipe 1. The opening / closing element 21 is adaptable to the outlet 10. By setting the filter element 20, the steam discharged from the potato peeler 5 into the exhaust pipe 1 can be filtered, avoiding the problem of impurities clogging the pipes when the steam is condensed into condensate and then recycled along with the condensate. For example, when the condensate is recycled to the heating system, since the steam has been filtered in advance, there are no impurities in the condensate after the steam is condensed into condensate through the heat exchange device 7. Therefore, when the condensate is recycled to the heating system, there will be no problem of impurities clogging the heating system pipes.

[0059] It is necessary to understand that, such as Figure 1 As shown, when scalding potatoes using the potato peeler 5, the steam generated by the potato peeler 5 is relatively fast and needs to be discharged quickly. Therefore, this steam exhaust device for potato peeling equipment also includes a negative pressure pump 6. The negative pressure pump 6 is located between the steam exhaust device and the heat exchange device 7 and is connected to the pipelines of the steam exhaust device and the heat exchange device 7 respectively, thereby ensuring the steam discharge speed from the potato peeler 5, so that the scalding rate of the potatoes will not be affected by the slow steam discharge speed.

[0060] It is important to understand that the impurities discharged from the potato peeler 5 are from potatoes that have been scalded with steam, and the skin and flesh have been separated. Furthermore, because the steam is discharged at a relatively high speed and pressure after peeling, some potato skin and dirt will be mixed in with the discharged steam.

[0061] More specifically, the cleaning component 3 is disposed on the outer wall of the exhaust pipe 1, on the other side of the exhaust pipe 1 in the circumferential direction relative to the opening and closing component 21. The cleaning component 3 includes a cleaning component 30, which is adapted to the through port 11 and can be moved radially along the exhaust pipe 1 and extend into the exhaust pipe 1 through the through port 11.

[0062] More specifically, in the axial direction of the exhaust pipe 1, the side end face of the filter element 20 near the outlet 10, the downstream edge of the outlet 10, and the bottom wall of the cleaning element 30 are aligned with each other; and the cleaning element 30 moves in the radial direction of the exhaust pipe 1, with its bottom wall adhering to the filter element 20 to clean the filter element 20.

[0063] In summary, the working principle of this exhaust device for potato peeling equipment is as follows: After the exhaust device is installed on the potato peeling equipment, when the equipment is working, the steam from scalding the potatoes in the potato peeling machine 5 is discharged from the steam outlet of the potato peeling machine 5 and enters the exhaust pipe 1. Then, the discharged steam is filtered by the filter element 20 installed in the exhaust pipe 1, thereby removing impurities from the discharged steam. When the filter element 20 is blocked, the air pressure in the exhaust pipe 1 rises to a certain threshold (e.g., when the filter element 20 is blocked, the steam pressure rises to a certain threshold). Steam (above 2.0 MPa) flows out from the pressure relief port 12 and does not flow back into the potato peeling equipment, ensuring the reliability of the potato peeling equipment. Furthermore, when the pressure relief component 32 is opened, the operator can push the cleaning component 30 to move radially along the exhaust pipe 1, cleaning the filter component 20 through the cleaning component 30. By cleaning the filter component 20 in this way, it is not necessary to shut down the potato peeling equipment to filter and clean the filter component 20, ensuring the potato peeling efficiency of the potato peeling equipment.

[0064] In the embodiments disclosed in this example, as Figure 1 and Figure 2 As shown, the structure and arrangement of the cleaning component 3 of the exhaust device for potato peeling equipment will be further explained below.

[0065] The cleaning component 3 includes a cleaning member 30 that is adapted to the through port 11 and can be moved radially along the exhaust pipe 1 and extends into the exhaust pipe 1 through the through port 11, a pressure relief member 32 that is adapted to the pressure relief port 12 and can be opened, and a drive member 31 that is disposed between the pressure relief member 32 and the cleaning member 30.

[0066] More specifically, the structure and arrangement of the pressure relief component 32 are not limited. For example, it can be configured as a pressure relief valve, a pressure valve, etc., which is not limited in this embodiment. However, it should be understood that the pressure relief component 32 can automatically open when the pressure in the exhaust pipe 1 reaches a certain threshold. The pressure threshold in the exhaust pipe 1 can be set to 1.5 MPa, 2 MPa, etc., and those skilled in the art can design it according to their needs. This embodiment is not limited in this embodiment.

[0067] The structure and arrangement of the drive component 31 will be further explained below.

[0068] The drive component 31 includes a rotating component 310 and a drive component 311 disposed between the rotating component 310 and the cleaning component 30. The rotating component 310 is disposed outside the pressure relief port 12 and directly opposite the pressure relief component 32. The end of the rotating shaft 312 of the rotating component 310 away from the pressure relief port 12 is connected to the cleaning component 30 by the drive component 311. The rotating component 310 is connected to the cleaning component 30 through the drive component 311. When the rotating component 310 rotates, it drives the drive component 311 and drives the cleaning component 30 to move relative to the filter component 20 along the passage 11 to clean the filter component 20.

[0069] Specifically, when the potato peeling equipment is working, the steam from the scalded potatoes in the potato peeling machine 5 is discharged from the steam outlet of the potato peeling machine 5 into the exhaust pipe 1, and continuously flows from the exhaust pipe 1 to the heat exchange device 7; at the same time, the steam passing through the exhaust pipe 1 is filtered by the filter component 20, so that the steam entering the heat exchange device 7 remains clean, avoiding the impact of impurities on the subsequent steam reuse.

[0070] More specifically, the drive component 31 also includes a venting pipe 313, wherein one end of the venting pipe 313 surrounds the pressure relief port 12 and is fixedly connected to the outer wall of the exhaust pipe 1, and the other end is connected to the external space; the rotating component 310 is sleeved on the rotating shaft 312 and is located inside the venting pipe 313 at a position opposite to the pressure relief port 12; the rotating shaft 312 extends parallel to the exhaust pipe 1, one end is rotatably connected to the inner wall of the venting pipe 313 away from the cleaning component 30, and the other end extends into the cleaning component 30 and is connected to the drive component 311.

[0071] More specifically, by setting up a vent pipe 313, when impurities clog the filter component 20 and the air pressure in the exhaust pipe 1 rises to a certain threshold (such as above 2.0 MPa), the pressure relief component 32 opens, and steam flows from the pressure relief port 12 of the exhaust pipe 1 into the vent pipe 313. The vent pipe 313 collects the steam flowing out of the exhaust pipe 1, thereby increasing the thrust of the steam on the rotating component 310, thus increasing the driving force of the steam on the rotating component 310, thereby ensuring that the rotating component 310 can rotate reliably and drive the linkage component 311 to move the cleaning component 30 to clean the filter component 20.

[0072] More specifically, the structure and arrangement of the driving component 311 and the rotating component 310 are not limited.

[0073] In one feasible embodiment, the rotating member 310 is configured as a plurality of rotating blades 3101, and the driving member 311 is configured as a rotating gear; wherein, the plurality of rotating blades 3101 are fixed at intervals along the circumferential direction of the rotating shaft 312 to the peripheral side wall of the rotating shaft 312, and the plurality of rotating blades 3101 are all inclined at a certain angle toward the same side of the venting pipe 313; the rotating gear is fixedly connected to the other end of the rotating shaft 312 and is connected in a transmission manner to the cleaning component 30.

[0074] It should be understood that the number of rotating blades 3101 can be set to 2, 3, 5, etc. This embodiment does not limit this.

[0075] Specifically, since multiple rotating blades 3101 are all tilted at a certain angle toward the same side of the vent pipe 313, when the pressure relief component 32 is opened, steam flows from the pressure relief port 12 of the exhaust pipe 1 into the vent pipe 313. This ensures that the steam drives the multiple blades to rotate the shaft 312 in a specific direction, reliably driving the rotating gear to rotate and move the cleaning component 30 relative to the filter component 20 to clean the filter component 20. It should be understood that the angle at which the multiple rotating blades 3101 are tilted toward the same side of the vent pipe 313 can be 30°, 34°, 37°, etc.

[0076] The structure and arrangement of the cleaning component 30 will be further explained below.

[0077] The cleaning component 30 includes a limiting member 300, a transmission member 301, and a cleaning member 302 arranged sequentially along the width of the exhaust pipe 1. One end of the transmission member 301 is fixedly connected to one end of the cleaning member 302, and the other end is fixedly connected to the limiting member 300. The other end of the cleaning member 302 extends at least partially into the passage 11. Furthermore, the rotating gear is connected to the transmission member 301 to transmit power from the drive member 31 to the cleaning component 30. The cleaning member 302 can clean the filter member 20, and the limiting member 300 can restrict the displacement of the transmission member 301 to prevent the gear from disengaging from the transmission member 301 due to excessive displacement.

[0078] Specifically, the arrangement of the structure of the limiting component 300, the transmission component 301, and the cleaning component 302 is not limited.

[0079] In one feasible embodiment, the transmission component 301 is configured as a rack, the cleaning component 302 is configured as a cleaning push plate 3020, and the limiting component 300 is configured as a limiting plate 3001. The cleaning push plate 3020 and the limiting plate 3001 are parallel to each other. One end of the rack is fixedly connected to a side wall of the cleaning push plate 3020, and the other end extends in a direction away from the cleaning push plate 3020 and is fixedly connected to a side wall of the limiting plate 3001. The rotating gear meshes with the rack.

[0080] Specifically, when the pressure relief component 32 is opened, steam flows from the pressure relief port 12 of the exhaust pipe 1 into the vent pipe 313. The steam then drives the rotating blades, causing the rotating shaft 312 to rotate and in conjunction with the rotating gear. The rotating gear drives the rack to move along the width direction of the exhaust pipe 1, which in turn moves the cleaning push plate 3020 along the width direction of the exhaust pipe 1 to clean the filter component 20. Furthermore, the cleaning push plate 3020 extends into the outlet 10 to push open the opening and closing component 21, thereby achieving the discharge of impurities. With this configuration, the filter component 20 can be cleaned without manual operation, which has the advantage of reducing labor costs.

[0081] It should be understood that, along the axial direction of the exhaust pipe 1, the cleaning push plate 3020 has a through hole extending through it, and the radial dimension of this through hole is larger than the radial dimension of the filter holes of the filter plate 200. After the cleaning push plate 3020 cleans the filter plate 200, steam can flow to the heat exchange device 7 through the through hole of the cleaning push plate 3020 and the filter holes of the filter plate 200.

[0082] In the embodiments disclosed in this example, as Figure 1 and Figure 2 As shown below, the structure and arrangement of the filter assembly 2 of the exhaust device for potato peeling equipment will be further explained.

[0083] The filter assembly 2 includes a filter element 20 and an opening / closing element 21. The filter element 20 is disposed in the exhaust pipe 1, located downstream of the outlet 10 in the steam flow direction, and its peripheral wall is attached to the inner wall of the exhaust pipe 1. The opening / closing element 21 is adaptable to the outlet 10.

[0084] Specifically, the structure and arrangement of the filter element 20 are not limited.

[0085] In one feasible embodiment, the filter element 20 is configured as a filter plate 200 with multiple filter holes thereon. The exhaust pipe 1 has a rectangular cross-section, with the outlet 10 and the through port 11 located on opposite side walls of the exhaust pipe 1, and the opening width of the outlet 10 and the through port 11 being equal to the width of their respective side walls. The filter plate 200 is fixedly installed inside the exhaust pipe 1, and one side wall of both the outlet 10 and the through port 11 is flush with the side wall of the filter plate 200 near the steam inlet of the exhaust pipe 1. Furthermore, the cleaning push plate 3020 is also adapted to the outlet 10. With this configuration, when the cleaning push plate 3020 moves to clean the filter plate 200, it can pass through all positions of the side wall of the filter plate 200 near the steam inlet, thereby ensuring complete cleaning of the filter plate 200.

[0086] More specifically, the end wall of the cleaning push plate 3020 located inside the through port 11 is also provided with a wedge-shaped opening opposite to the outlet port 10, and the opening size of the wedge-shaped opening in the axial direction of the exhaust pipe 1 is equal to the opening size of the outlet port 10 in the axial direction of the exhaust pipe 1. This arrangement allows the cleaning push plate 3020 to move and clean the filter plate 200, so that as impurities gradually accumulate on the filter plate 200, the wedge-shaped opening can limit the impurities, keeping them within the opening cavity formed by the wedge-shaped opening, thus allowing the impurities to be smoothly discharged from the outlet port 10.

[0087] More specifically, the structure and arrangement of the opening and closing component 21 are not limited.

[0088] In one feasible embodiment, the opening and closing component 21 includes a "T"-shaped plate 210 and a pair of springs 211. A pair of mounting holes are provided on the periphery of the outlet 10. The pair of springs 211 and the pair of mounting holes correspond to and are adapted to each other. One end of the pair of springs 211 is disposed on the side of the flange of the "T"-shaped plate 210 near the exhaust pipe 1, relative to the web of the "T"-shaped plate 210. The other end extends into the pair of mounting holes and is fixedly connected to the side wall of the flange of the "T"-shaped plate 210 away from the mounting holes. The web of the "T"-shaped plate 210 extends into the outlet 10 and is adapted to the outlet 10.

[0089] Specifically, when the cleaning component 30 moves to clean the filter component 20, the cleaning component 30 can open the outlet 10 by pushing the web of the "T"-shaped plate 210, and then push the impurities out of the outlet 10 and discharge them into the external space; after the cleaning component 30 has completely pushed the impurities out of the outlet 10, the filter component 20 is turned on, and the steam continues to flow to the heat exchange device 7, and the pressure relief component 32 is closed; at the same time, the outlet 10 is closed again under the action of the spring 211's restoring force, and the "T"-shaped plate 210 gradually resets and pushes the cleaning component 30 to retract relative to the outlet 10.

[0090] More specifically, by setting a pair of springs 211, the rebound force of the "T" plate 210 can be increased, so that the "T" plate 210 can reliably close the outlet 10.

[0091] In the embodiments disclosed in this example, as Figure 1 and Figure 2 As shown, this exhaust device for potato peeling equipment also includes a support housing 4, which has a connection port and is fixedly installed on the outer wall of the exhaust pipe 1. The drive component 31 and the cleaning component 30 are both located inside the support housing 4, and the other end of the exhaust pipe 313 extends into the connection port and communicates with the external space.

[0092] Specifically, by providing a support housing 4, the drive component 31 and the cleaning component 30 can be protected and supported, reducing the risk of damage to the drive component 31 and the cleaning component 30 due to operator error during transportation or installation of the exhaust device.

[0093] In summary, this utility model provides a steam exhaust device for potato peeling equipment. The steam exhaust device will be described below in conjunction with the working process.

[0094] After this exhaust device is installed on the potato peeling equipment, during operation, under the pressure boosting action of the negative pressure pump 6, the steam from scalding the potatoes in the potato peeling machine 5 is discharged from the steam outlet of the potato peeling machine 5 and enters the exhaust pipe 1. Then, the discharged steam is filtered by the filter component 20 installed in the exhaust pipe 1, thereby removing impurities from the exhaust steam. When the filter component 20 becomes clogged, the air pressure in the exhaust pipe 1 rises to a certain threshold (e.g., above 2.0 MPa), and the pressure relief component... When pressure relief port 32 is opened, steam flows out from pressure relief port 12 and will not flow back into the potato peeling equipment, ensuring the reliability of the potato peeling equipment. Furthermore, when pressure relief port 32 is opened, the operator can push cleaning component 30 to move radially along exhaust pipe 1 to clean filter component 20. By cleaning filter component 20 in this way, it is not necessary to shut down the potato peeling equipment to filter and clean filter component 20, thus ensuring the peeling efficiency of potato peeling equipment.
