Description

Technical Field

[0001] This invention relates to the field of rice processing equipment technology, specifically to an anti-fog viewing window device for rice processing equipment. Background Technology

[0002] During the production and operation of rice processing equipment, workers need to observe the internal processing status in real time through the observation window on the equipment to determine whether the processing flow is normal. Currently, the observation windows of rice processing equipment are mostly single- or double-layered glass structures, directly installed at the observation port of the equipment, relying on the transparency of the glass itself to achieve the observation function.

[0003] However, in actual rice processing environments, there is a significant temperature difference between the internal temperature of the equipment and the external temperature. This temperature difference easily causes fogging on the surface of the observation window glass, obstructing the operator's view. Simultaneously, the rice processing process generates a large amount of dust, which easily disperses and adheres to the glass surface, forming a fog that further affects the observation effect. To address this issue, some existing equipment incorporates a simple wiping structure at the observation window, requiring operators to manually disassemble the wiping components to clean the glass. This operation is cumbersome and interrupts the normal processing and observation process. Other equipment adds a fan to blow dust away from the observation window, but the dust removal effect is limited and cannot fundamentally solve the problem of glass fogging. Furthermore, the vibration generated by the fan may affect the stability of the equipment. In addition, the existing dustproof structure of the observation window lacks effective dust collection and filtration. Dust easily accumulates around the observation window, not only re-adhering to the glass surface but also potentially entering other internal components of the equipment, affecting its overall lifespan and failing to meet the requirements for clear and stable observation windows during rice processing. Summary of the Invention

[0004] The problem to be solved by this invention is to provide a dust-proof viewing window device for rice processing equipment, which can solve the problem of fogging and dust adhesion in the viewing window from the root, ensure the clarity of the viewing window, and is easy to operate without affecting the normal operation of the equipment.

[0005] The technical solution provided by this invention to solve the above problems is as follows: a powder-proof and fog-proof viewing window device for rice processing equipment, comprising a mounting frame, a cover plate, fasteners, a glass plate, an air valve, and a shock-absorbing ring. The cover plate is installed on the top of the mounting frame by several fasteners. Glass plates are embedded in both the cover plate and the mounting frame. The air valve is installed on the mounting frame. The shock-absorbing ring is installed at the bottom of the mounting frame. The device also includes a sliding frame, a scraper, a first limiting plate, a second limiting plate, and a magnetic suction element. The symmetrically arranged first limiting plates are fixed to the bottom of the mounting frame. The sliding frame is slidably connected between the symmetrically arranged first limiting plates. The scraper is fixed to the top of the sliding frame. The symmetrically arranged second limiting plates are fixed to the top of the mounting frame. A magnetic suction element is slidably connected in each second limiting plate.

[0006] More preferably, the space between the cover plate and the mounting plate is evacuated by a valve. The vacuum can isolate the temperature and prevent the glass from fogging due to excessive temperature difference.

[0007] More preferably, the scraper is made of silicone and is used to scrape off the powder mist adhering to the glass slide.

[0008] More preferably, the sliding frame is made of metal, and the symmetrically arranged magnetic components are all attracted to the sliding frame.

[0009] More preferably, it also includes a fixing frame, a filter plate and a negative pressure component. The symmetrically arranged fixing frames are fixed to the lower part of the mounting frame. Each fixing frame is equipped with a filter plate and a negative pressure component is installed on each fixing frame.

[0010] More preferably, the negative pressure component draws the dust from the mounting frame into the fixed frame, preventing the dust from adhering to the glass plate.

[0011] More preferably, it also includes a lifting frame, a guide frame, springs, and brush plates. The symmetrically arranged guide frames are all fixed to the mounting frame. Each guide frame has a slidingly connected lifting frame. Each lifting frame is connected to the corresponding guide frame by symmetrically arranged springs. Each lifting frame has a brush plate fixed to its bottom. Each brush plate is in contact with the corresponding filter plate.

[0012] More preferably, when the lifting frame is pressed, the spring is compressed, and the lifting frame moves the brush plate downward. When the lifting frame is released, the spring returns to its original position, and the lifting frame moves upward to return to its original position, which in turn moves the brush plate upward. This allows the lifting frame to move the brush plate back and forth to remove the dust adhering to the filter plate.

[0013] More preferably, it also includes fixed posts, barrier frames and expansion frames, with symmetrically arranged fixed posts fixed to the side of each fixed frame, barrier frames snapped between the fixed posts on each fixed frame, and expansion frames fixed inside each fixed frame.

[0014] More preferably, the barrier frame is an upward-facing figure-eight shape to prevent dust at the bottom from flowing upward and adhering to the negative pressure component, and the inner wall of the expansion frame is a horizontal figure-eight sloping surface to concentrate air and guide the dust.

[0015] Compared with the prior art, the advantages of the present invention are: the present invention can avoid excessive temperature difference between the inside and outside of the equipment, which would cause the glass slide to fog up, by means of vacuum insulation, thus ensuring the clarity of the observation window from the source. The silicone scraper can directly scrape off the powder fog on the surface of the glass slide without disassembling the device, making the operation convenient and without damaging the glass slide.

[0016] The negative pressure assembly can draw dust from the mounting frame into the fixed frame and intercept it through the filter plate, reducing the possibility of dust adhering to the glass plate and forming dust mist. The lifting frame drives the brush plate to move back and forth, which can remove dust on the filter plate in time, ensuring the filtration efficiency of the filter plate and maintaining the stable operation of the negative pressure assembly.

[0017] The figure-eight-shaped barrier frame prevents dust from the bottom of the fixed frame from flowing upwards and adhering to the negative pressure component, ensuring the normal operation of the negative pressure component. The figure-eight-shaped slope of the expansion frame can concentrate the airflow and guide the dust, improving the efficiency of dust collection.

[0018] The shock-absorbing ring at the bottom of the mounting frame can reduce the vibration generated during equipment operation, prevent the connection of various components from becoming loose, and extend the overall service life of the device. Attached Figure Description

[0034] Example: As shown in the attached figure, a dust-proof viewing window device for rice processing equipment includes a mounting frame 1, a cover plate 2, fasteners 3, a glass plate 4, an air valve 5, and a shock-absorbing ring 6. The cover plate 2 is mounted on the top of the mounting frame 1 by several fasteners 3. Glass plates 4 are embedded in both the cover plate 2 and the mounting frame 1. The air valve 5 is mounted on the mounting frame 1 and creates a vacuum between the cover plate 2 and the mounting plate. This vacuum isolates the temperature, preventing excessive temperature differences from causing fogging of the glass plate 4. The shock-absorbing ring 6 is mounted on the bottom of the mounting frame 1. The device also includes a sliding frame 7 and a scraper. 8. A first limiting plate 9, a second limiting plate 10, and a magnetic suction element 11. The first limiting plates 9, which are symmetrically arranged, are fixed to the bottom of the mounting frame 1. The sliding frame 7 is slidably connected between the symmetrically arranged first limiting plates 9. The scraper 8 is fixed to the top of the sliding frame 7. The scraper 8 is made of silicone and is used to scrape off the powder and mist adhering to the glass plate 4. The second limiting plates 10, which are symmetrically arranged, are fixed to the top of the mounting frame 1. Each second limiting plate 10 is slidably connected to a magnetic suction element 11. The sliding frame 7 is made of metal, and the symmetrically arranged magnetic suction elements 11 are all attracted to the sliding frame 7.

[0035] In this embodiment, specifically, it also includes a fixed frame 12, a filter plate 13 and a negative pressure component 14. The symmetrically arranged fixed frames 12 are fixed to the lower part of the mounting frame 1. Each fixed frame 12 is equipped with a filter plate 13, and each fixed frame 12 is equipped with a negative pressure component 14. The negative pressure component 14 draws the dust in the mounting frame 1 into the fixed frame 12 to prevent the dust from adhering to the glass plate 4. Furthermore, it also includes a lifting frame 15, a guide frame 16, a spring 17, and a brush plate 18. The symmetrically arranged guide frames 16 are all fixed to the mounting frame 1. Each guide frame 16 is slidably connected to a lifting frame 15. Each lifting frame 15 is connected to a corresponding guide frame 16 by a symmetrically arranged spring 17. Each lifting frame 15 has a brush plate 18 fixed to its bottom. Each brush plate 18 is in contact with a corresponding filter plate 13. When the lifting frame 15 is pressed, the spring 17 is compressed, and the lifting frame 15 drives the brush plate 18 to move downward. When the lifting frame 15 is released, the spring 17 returns to its original position, driving the lifting frame 15 to move upward and reset, thereby driving the brush plate 18 to move upward. This allows the lifting frame 15 to drive the brush plate 18 to reciprocate and remove the dust adhering to the filter plate 13. Secondly, it also includes fixed columns 19, barrier frames 20 and expansion frames 21. Each fixed frame 12 is fixedly connected to a symmetrically arranged fixed column 19 on its side. A barrier frame 20 is snapped between the fixed columns 19 on each fixed frame 12. The barrier frame 20 is an upward-facing figure-eight shape to prevent dust at the bottom from flowing upward and adhering to the negative pressure component 14. An expansion frame 21 is fixedly connected inside each fixed frame 12. The inner wall of the expansion frame 21 is a horizontal figure-eight sloping surface, which is used to gather air and guide dust.

[0036] Install the mounting frame 1 at the observation window position of the rice processing equipment, and then install the cover plate 2 on top of the mounting frame 1 with fasteners 3 to ensure that the cover plate 2 and the glass plate 4 inside the mounting frame 1 are in a stable position. Then operate the air valve 5 to evacuate the space between the cover plate 2 and the mounting frame 1 into a vacuum state. The vacuum environment can isolate the temperature and prevent the glass plate 4 from fogging due to excessive temperature difference between the inside and outside of the equipment. This reduces the possibility of fogging of the glass plate 4 from the root and ensures the basic clarity of the observation window. The shock-absorbing ring 6 installed at the bottom of the mounting frame 1 can reduce the vibration generated during the operation of the equipment, prevent the vibration from causing the connection of various components to loosen, and extend the overall service life of the device. When dust adheres to the surface of the glass slide 4 and affects observation, the magnetic suction component 11 installed in the second limiting plate 10 is moved. Since the sliding frame 7 is made of metal, the magnetic suction component 11 will generate an attraction force with the sliding frame 7, causing the sliding frame 7 to slide between the first limiting plates 9. The scraper 8 fixed to the top of the sliding frame 7 moves accordingly, scraping the surface of the glass slide 4. The scraper 8 is made of silicone, which is soft and conforms well, directly removing the dust from the glass slide 4. The defogging operation can be completed without disassembling the device, which is convenient and will not damage the glass slide 4, ensuring that the observation work can continue. During the operation of the equipment, the negative pressure component 14 installed on the fixed frame 12 is activated. The negative pressure component 14 will suck the dust in the mounting frame 1 into the fixed frame 12. The dust is intercepted when it passes through the filter plate 13 in the fixed frame 12, preventing the dust from drifting in the mounting frame 1 and adhering to the glass slide 4, reducing the formation of dust, maintaining the cleanliness of the glass slide 4, and reducing the cleaning frequency of the scraper 8. When the dust adhering to the filter plate 13 is too much and affects the filtration effect, press the lifting frame 15. The lifting frame 15 moves downward in the guide frame 16, the spring 17 is compressed, and the brush plate 18 fixed to the bottom of the lifting frame 15 moves downward to brush the surface of the filter plate 13. After the lifting frame 15 is released, the spring 17 returns to its original position, driving the lifting frame 15 and the brush plate 18 to move upward. This operation is repeated to realize the reciprocating cleaning of the filter plate 13 by the brush plate 18, which can remove the dust on the filter plate 13 in time, ensure the filtration efficiency of the filter plate 13, and ensure that the dust collection of the negative pressure component 14 can be carried out stably. During the dust collection process, the barrier frame 20 installed between the fixed columns 19 on the side of the fixed frame 12 is shaped like an upward V-shape, which can prevent the dust accumulated at the bottom of the fixed frame 12 from flowing upward and prevent the dust from adhering to the negative pressure component 14 and affecting its normal operation. The inner wall of the expansion frame 21 inside the fixed frame 12 is a horizontal V-shaped slope, which can concentrate the airflow and guide the dust, so that the dust can be smoothly adsorbed into the fixed frame 12, optimize the internal environment of dust collection, improve the efficiency of dust collection, and extend the service life of the negative pressure component 14.
