Description

Technical Field

[0001] This utility model relates to the field of wet granulation machine technology, and specifically to a feeding device for a wet granulation machine. Background Technology

[0002] A wet granulator is a device for wet granulation of materials. The materials and binders are mixed in a cylindrical container by a stirring paddle to form a moist soft material. During this process, the materials are fully mixed and gradually form liquid bridges, transforming into a loose soft material. After the mixed soft material reaches the appropriate state, it is cut into uniform wet granules by a side-mounted high-speed cutter. These wet granules maintain good flowability and compressibility during the cutting process, which facilitates subsequent processes.

[0003] Traditionally, raw material powder is directly poured into wet granulation machines without screening, which may result in coarse particles being mixed in and affecting the quality of the granules.

[0004] The prior art proposes a Chinese patent with publication number CN220919088U to solve the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: A feeding device for a wet granulation machine includes a housing, a feeding hopper installed on the top of the housing, a drive motor installed on the narrower side of the outer surface of the housing, a movable block embedded on the wider side of the outer surface of the housing, and a connecting block installed on the outer side of the movable block. This utility model, through the design of a feeding device for a wet granulation machine, uses a drive motor to drive a rotating rod to rotate, which in turn drives two cams to rotate, creating a vibration effect that pushes the top of the screen... The fine raw materials are screened through a screen and flow onto an inclined plate, finally exiting through the discharge port into the wet granulation machine. The moving block drives the scraper to scrape the top of the screen, cleaning out the remaining coarse raw materials from the inside of the box. This effectively solves the problem that traditional wet granulation machines cannot screen raw materials during feeding, resulting in coarse particles entering the processing and affecting particle quality. However, after the above solution involves scraping the screen surface for a long time, the direct contact between the scraper and the screen will accelerate the wear of the screen, leading to a decrease in screen screening efficiency, uneven particle size, and even leakage, thus affecting the screening effect. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for a wet granulation machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A feeding device for a wet granulation machine includes a granulator body; a feeding box is fixedly installed on the top of the granulator body, a controller is fixedly connected to one end of the feeding box, a pull plate is connected to one side of the feeding box via a bolt, the pull plate is tightly fitted to one end of the feeding box, a filter screen is fixedly installed inside the feeding box, a dust collection box is set on the top of the filter screen, several negative pressure fans are fixedly installed on the top of the dust collection box, a partition is fixedly installed inside the dust collection box, a dust suction port is opened at the bottom of the dust collection box on the other side of the partition, brushes are fixedly connected to the bottom surface of the dust collection box on both sides of the dust suction port, the bottom surface of each brush is in contact with the surface of the filter screen, a baffle plate is slidably installed on one side of the dust collection box, and connecting rods are fixedly installed on the top of the dust collection box outside the negative pressure fans, the side surface of each connecting rod is fixedly connected to the surface of the pull plate.

[0008] After prolonged scraping of the screen surface by a scraper, the direct contact between the scraper and the screen accelerates screen wear, leading to reduced screening efficiency, uneven particle size, and even material leakage, thus affecting the screening effect. In this application, the negative pressure fan creates negative pressure inside the dust collection box, allowing excess impurities on the filter screen surface to be sucked into the dust collection box through the suction port. When the negative pressure fan stops working, the impurities fall to the top of the guide plate, thus collecting them. Pulling the pull plate to one side moves the dust collection box synchronously to one side, adjusting the suction position and causing the brush to slide along the filter screen surface, separating the impurities adhering to the filter screen surface and sucking them into the dust collection box for cleaning. This structure replaces the scraper for cleaning the filter screen surface, reducing the possibility of wear and tear and extending the filter screen's service life.

[0009] A further improvement of this utility model is that a support plate is attached to the bottom surface of the filter screen. The support plate is located directly below each brush. Fixing rods are fixedly installed on both ends of one side of the support plate. One side of each fixing rod is fixedly connected to the surface of the pull plate.

[0010] In the above-mentioned technical solution, when the brush slides along the surface of the filter screen, it exerts a certain pressure on the filter screen. After long-term operation, the surface of the filter screen is easily squeezed and deformed, thereby reducing the effectiveness of the filter screen. In this application, by attaching the support plate to the bottom surface of the filter screen, the support plate can be moved synchronously during the movement of the pull plate and the brush. During the process of the brush sliding along the surface of the filter screen, the support plate can support the bottom surface of the filter screen, thereby reducing the possibility of the filter screen surface being squeezed and deformed, and improving the protection effect of the filter screen.

[0011] A further improvement of this utility model is that sliders are fixedly installed on both ends of the support plate, and a pair of grooves matching the shape of each slider are opened on the inner wall of the feed box, with each slider slidingly connected to the inside of each groove.

[0012] By adopting the above technical solution, the contact area between the two sides of the support plate and the inner wall of the feed box can be increased by setting sliders and grooves, thereby guiding and limiting the sliding trajectory of the support plate and ensuring that the support plate can slide along the bottom surface of the filter screen.

[0013] A further improvement of the present invention is that a baffle is fixedly installed inside the feed box at one end of the dust collection box, and a sliding plate is slidably connected inside the baffle by several springs. The bottom surface of the sliding plate is lower than the top surface of the dust collection box.

[0014] In the above-mentioned technical solution, when the material is poured into the internal triangular plate of the feeding box from the top, some material tends to accumulate on the top surface of the dust collection box, resulting in waste and affecting subsequent processing. In this application, by installing baffles and sliding plates, one side of the dust collection box can be blocked to prevent material from falling onto the top surface of the dust collection box and causing waste.

[0015] A further improvement of this utility model is that: the two sides of the slide plate near the bottom are provided with inward inclined surfaces, and the inclined surface of the other side of the slide plate is pressed against the surface of the dust collection box.

[0016] The above technical solution involves setting the slide plate into a special shape so that after the slide plate is moved to a certain height, it can be pressed upwards during the movement of the dust collection box, thereby reducing the impact on the movement of the dust collection box.

[0017] A further improvement of this utility model is that a triangular plate is fixedly installed on the top of the material blocking plate, and the other side surface of the triangular plate is in contact with the surface of the dust collection box.

[0018] In the above technical solution, by installing a triangular plate, when the material falls to the top of the blocking plate, the material can slide down along the triangular plate, thereby preventing some material from accumulating on the top of the blocking plate and causing waste.

[0019] A further improvement of the present invention is that a guide plate is fixedly installed inside the dust collection box at one end of the partition, and the top surface of the guide plate is provided with an inclined surface that slopes to one side and bottom.

[0020] In the above technical solution, by installing a guide plate, after the blocking plate is moved to the top, the impurities can slide out to one side along the inclined surface of the guide plate, so as to facilitate the removal of the impurities from the dust collection box, which provides convenience for the operator.

[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0022] 1. This utility model provides a feeding device for a wet granulation machine. Through the cooperation between the negative pressure fan and the brush, the dust collection box can be moved synchronously to one side when the pull plate is pulled to one side. This allows the brush to scrape the impurities adhering to the filter screen surface, separating them from the filter screen surface. Then, the negative pressure fan sucks the impurities into the dust collection box, thereby cleaning the filter screen surface. This replaces the cleaning work of the scraper on the filter screen surface, thereby reducing the possibility of wear on the filter screen surface and extending the service life of the filter screen.

[0023] 2. This utility model provides a feeding device for a wet granulation machine. By installing a support plate, it is made to fit in close contact with the bottom surface of the filter screen. As the brush slides along the surface of the filter screen, the support plate can slide synchronously along the bottom surface of the filter screen, supporting the bottom surface of the filter screen. This reduces the possibility of the filter screen surface being squeezed and deformed, and improves the protection effect of the filter screen.

[0024] 3. This utility model provides a feeding device for a wet granulation machine. Through the cooperation between the baffle, the sliding plate and the spring, one side of the dust collection box can be blocked to prevent the material from falling and accumulating on the top surface of the dust collection box. In addition, the triangular plate can prevent some material from accumulating on the top of the blocking plate, thereby reducing waste and facilitating subsequent wet granulation processing of the material.

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] Example 1

[0035] like Figure 1 , Figure 3 and Figure 6 As shown, this utility model provides a feeding device for a wet granulation machine, including a granulator body 1; a feeding box 2 is fixedly installed on the top of the granulator body 1, a controller 4 is fixedly connected to one end of the feeding box 2, a pull plate 3 is connected to one side of the surface of the feeding box 2 by a bolt, the pull plate 3 is tightly fitted to one end of the surface of the feeding box 2, a filter screen 5 is fixedly installed inside the feeding box 2, a dust collection box 6 is provided on the top of the filter screen 5, several negative pressure fans 13 are fixedly installed on the top of the dust collection box 6, a partition 18 is fixedly installed inside the dust collection box 6, a dust suction port is opened at the bottom of the dust collection box 6 on the other side of the partition 18, a brush 15 is fixedly connected to the bottom surface of the dust collection box 6 on both sides of the dust suction port, the bottom surface of each brush 15 is in contact with the surface of the filter screen 5, a material blocking plate 9 is slidably installed on one side of the surface of the dust collection box 6, and a connecting rod 12 is fixedly installed on the top of the dust collection box 6 outside the negative pressure fans 13, the side surface of each connecting rod 12 is fixedly connected to the surface of the pull plate 3.

[0036] In this embodiment, after scraping the screen surface for a long time, the direct contact between the scraped material and the screen will accelerate the wear of the screen, resulting in reduced screening efficiency, uneven particle size, and even material leakage, thus affecting the screening effect. In this application, by turning on the negative pressure fan 13, a negative pressure can be formed inside the dust collection box 6, which can then suck excess impurities on the surface of the filter screen 5 into the dust collection box 6 through the suction port. When the negative pressure fan 13 stops working, the impurities can fall to the top of the guide plate 19, thereby collecting the impurities. By pulling the pull plate 3 to one side, the dust collection box 6 can be moved synchronously to one side, thereby adjusting the suction position and causing the brush 15 to slide along the surface of the filter screen 5, thereby separating the impurities adhering to the surface of the filter screen 5 and sucking them into the dust collection box 6, thus cleaning the surface of the filter screen 5. The above structure replaces the scraper to clean the surface of the filter screen 5, reducing the possibility of wear on the surface of the filter screen 5 and thus extending the service life of the filter screen 5.

[0037] Example 2

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, based on Embodiment 1, the present invention provides the following technical solution: Preferably, a support plate 11 is attached to the bottom surface of the filter screen 5. The support plate 11 is located directly below each brush 15. Fixing rods 14 are fixedly installed on both ends of one side of the support plate 11. One side of each fixing rod 14 is fixedly connected to the surface of the pull plate 3. Slider 16 is fixedly installed on both ends of the support plate 11. A pair of sliding grooves matching the shape of each slider 16 are opened on the inner wall of the feed box 2. Each slider 16 is slidably connected to the inside of each sliding groove.

[0039] In this embodiment, when the brush 15 slides along the surface of the filter screen 5, the brush 15 exerts a certain pressure on the filter screen 5. After long-term operation, the surface of the filter screen 5 is easily squeezed and deformed, thereby reducing the effectiveness of the filter screen 5. In this application, by attaching the support plate 11 to the bottom surface of the filter screen 5, the support plate 11 can be moved synchronously during the movement of the pull plate 3 and the brush 15. During the sliding of the brush 15 along the surface of the filter screen 5, the support plate 11 can support the bottom surface of the filter screen 5, thereby reducing the possibility of the filter screen 5 being squeezed and deformed, and improving the protection effect of the filter screen 5. By setting the slider 16 and the groove, the contact area between the two sides of the support plate 11 and the inner wall of the feed box 2 can be expanded, thereby guiding and limiting the sliding trajectory of the support plate 11, ensuring that the support plate 11 can slide along the bottom surface of the filter screen 5.

[0040] Example 3

[0041] like Figure 1 , Figure 2 and Figure 5 As shown, based on Embodiment 2, the present invention provides the following technical solution: Preferably, a baffle 7 is fixedly installed inside the feed box 2 at one end of the dust collection box 6. A sliding plate 8 is slidably connected inside the baffle 7 by several springs 17. The bottom surface of the sliding plate 8 is lower than the top surface of the dust collection box 6. The two sides of the sliding plate 8 near the bottom are provided with inclined surfaces that slope inward. The inclined surface of the other side of the sliding plate 8 is pressed against the surface of the dust collection box 6. A triangular plate 10 is fixedly installed on the top of the baffle plate 9. The other side of the triangular plate 10 is in contact with the surface of the dust collection box 6. A guide plate 19 is fixedly installed inside the dust collection box 6 at one end of the partition plate 18. The top surface of the guide plate 19 is provided with an inclined surface that slopes to one side and to the bottom.

[0042] In this embodiment, when material is poured from the top of the feed box 2 into the internal triangular plate 10, some material tends to accumulate on the top surface of the dust collection box 6, resulting in waste and affecting subsequent processing. In this application, by installing the baffle 7 and the sliding plate 8, one side of the surface of the dust collection box 6 can be blocked to prevent material from falling onto the top surface of the dust collection box 6 and causing waste. Furthermore, by setting the sliding plate 8 into a special shape, after the sliding plate 8 is moved to a certain height, it can be pressed upwards during the movement of the dust collection box 6, thereby reducing the impact on the movement of the dust collection box 6. By installing the triangular plate 10, when material falls to the top of the blocking plate 9, the material can slide down along the triangular plate 10, thereby preventing some material from accumulating on the top of the blocking plate 9 and causing waste. By installing the guide plate 19, after the blocking plate 9 is moved upwards, impurities can slide down to one side along the inclined surface of the guide plate 19, making it easier to remove the impurities from inside the dust collection box 6, providing convenience for the operator.

[0043] The working principle of the feeding device used in the wet granulation machine is explained in detail below.

[0044] like Figures 1-6 As shown, the operator can pour the material to be granulated into the feed box 2, and then use the filter screen 5 to filter the material. The material with particle size smaller than the filter screen 5 can directly enter the granulator body 1 for wet granulation. After the material is processed, the operator can turn on the negative pressure fan 13 to suck the excess impurities on the surface of the filter screen 5 into the dust collection box 6 through the dust suction port. The operator then removes the plug at the top of the pull plate 3 and pulls the pull plate 3 to one side, which moves the dust collection box 6 to one side. At this time, the brush 15 can be moved. Sliding along the surface of the filter screen 5, the impurities adhering to the surface of the filter screen 5 are separated from its surface, so that the impurities can be sucked into the dust collection box 6, thereby cleaning the surface of the filter screen 5. During the movement of the brush 15, the support plate 11 can move synchronously along the bottom surface of the filter screen 5, thereby supporting the surface of the filter screen 5 and reducing the possibility of deformation of the filter screen 5. After cleaning, the operator can push the material blocking plate 9 to the top, and the impurities can automatically slide out from the inside of the dust collection box 6 along the surface of the guide plate 19, so as to facilitate the subsequent processing of the impurities.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
