A granulator discharge port anti-clogging and flow guiding device

Abstract

This invention provides an anti-clogging and diversion device for the discharge port of a granulator, relating to the field of granulation equipment technology. It includes a granulator discharge pipe, with an anti-clogging cylinder slidably fitted onto the bottom of the outer surface of the discharge pipe. The invention utilizes a drive motor to rotate a driving gear, which in turn drives a driven gear ring to rotate. The driven gear ring then rotates an annular rotating plate within the annular groove of the anti-clogging cylinder. This rotating plate, in turn, drives six unblocking components to simultaneously remove deposits from the inner wall of the discharge pipe. This structure achieves dual active anti-clogging of both the granulator discharge pipe and the inner wall of the anti-clogging cylinder, avoiding the problems of existing discharge pipes relying solely on manual cleaning and prone to clogging. It eliminates the need for frequent machine shutdowns for cleaning, significantly improving production continuity. Simultaneously, the tensioning spring adapts to discharge pipes of different inner diameters, ensuring the inner sliding scraper always fits tightly against the inner wall, improving the device's adaptability and eliminating the need for customized scrapers for different discharge pipes, thus reducing operating costs.

Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to a granulator discharge port anti-blocking and flow guiding device. Background Technology

[0002] A granulator is a mechanical device that processes materials into granules of a specific shape through processes such as heating, extrusion, and cutting. It is widely used in industries such as chemical, agricultural, and plastic processing. In the production process of a granulator, the discharge port is the key channel through which the material is output from inside the equipment to the subsequent conveying or collection stage after granulation. It is usually a tubular or funnel-shaped structure, and its unobstructed flow directly affects the production efficiency of the granulator and the quality of the granulated product.

[0003] The existing technology has the following shortcomings:

[0004] When the granulated material is discharged through the discharge pipe, it is prone to increased viscosity due to the cooling effect of contact with the pipe wall, thus firmly adhering to the inner wall of the discharge pipe. As production continues, the adhered material will accumulate and thicken, gradually narrowing the discharge channel. In severe cases, it may cause complete blockage of the discharge pipe. At this time, the staff needs to stop the machine and disassemble the discharge pipe for cleaning. This not only directly interrupts the production process and reduces production efficiency, but the scraping of tools during the cleaning process will also damage the inner wall of the discharge pipe and shorten its service life. Utility Model Content

[0005] This utility model proposes a granulator discharge port anti-blocking and diversion device, which has the advantages of actively removing the deposits on the discharge pipe and the inner wall of the anti-blocking cylinder, having a good anti-blocking effect, stable connection with the discharge pipe, convenient disassembly and assembly, and strong adaptability, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a granulator discharge port anti-blocking and diversion device, including a granulator discharge pipe, wherein three connecting components are arranged in a ring array on the outer surface of the granulator discharge pipe, and an anti-blocking cylinder is slidably sleeved at the bottom of the outer surface of the granulator discharge pipe.

[0007] The anti-clogging cylinder has an annular groove in the middle of its inner surface. A drive motor is fixedly connected to the front of the outer surface of the anti-clogging cylinder. The output shaft of the drive motor passes through the interior of the annular groove and is fixedly connected to a drive gear. A driven gear ring is meshed with the outer surface of the drive gear. An annular rotating plate is fixedly connected to the inner surface of the driven gear ring. The annular rotating plate is rotatably connected to the middle of the inner surface of the anti-clogging cylinder. Six unblocking components are fixedly connected in an annular array on the inner side of the annular rotating plate.

[0008] Preferably, the connecting assembly includes a C-shaped connecting frame, which is fixedly connected to the outer surface of the granulator discharge pipe. A transmission screw is rotatably connected to the middle of the C-shaped connecting frame, and the top end of the transmission screw extends through to the top of the C-shaped connecting frame and is fixedly connected to a knob.

[0009] Preferably, the outer surface of the transmission screw is threadedly connected to a threaded slide plate, the outer surface of the threaded slide plate is slidably connected to the inner surface of the C-shaped connecting frame, and a U-shaped clamping plate is rotatably connected to the left and right ends of the threaded slide plate. The top of the outer surface of the anti-blocking cylinder has three arc-shaped slots arranged in an annular array, and the U-shaped clamping plate is rotatably clamped to the inner surface of the arc-shaped slots.

[0010] Preferably, the unblocking component includes an external fixed scraper, which is fixedly connected to the inner surface of the annular rotating plate. The outer side of the external fixed scraper is in contact with the inner surface of the anti-blocking cylinder. A connecting slide plate is fixedly connected to the inner side of the external fixed scraper. An inner sliding scraper is provided on the outer surface of the connecting slide plate. The outer side of the inner sliding scraper is in contact with the inner surface of the granulator discharge pipe.

[0011] Preferably, the outer bottom of the inner sliding scraper is provided with a connecting groove, the connecting slide plate passes through the interior of the connecting groove and is fixedly connected to a sliding pressure plate, and both the upper and lower ends of the sliding pressure plate are slidably connected to horizontally penetrating guide posts.

[0012] Preferably, the two guide posts are fixedly connected to the upper and lower sides of the inner wall of the connecting slide groove, respectively. A clamping spring is provided on the outer surface of the guide post. One end of the clamping spring is fixedly connected to the side of the sliding pressure plate near the connecting slide plate, and the other end of the clamping spring is fixedly connected to the inner wall of the connecting slide groove.

[0013] 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:

[0014] 1. In this utility model, through the mutual cooperation between the drive motor, the driving gear, the driven gear ring, the annular rotating plate, and the unblocking components, the drive motor starts and drives the driving gear to rotate. The driving gear meshes and drives the driven gear ring to rotate. The driven gear ring drives the annular rotating plate to rotate within the annular groove of the anti-clogging cylinder. The annular rotating plate then drives the six unblocking components to rotate synchronously. In the unblocking components, the outer fixed scraper rotates with the annular rotating plate against the inner wall of the anti-clogging cylinder, which can scrape off the material adhering to the inner wall of the anti-clogging cylinder in real time. The inner sliding scraper, under the elastic force of the tensioning spring, ... By sliding the pressure plate along the guide column, it always keeps in close contact with the inner wall of the granulator's discharge pipe. As the annular rotating plate rotates, it simultaneously removes the deposits attached to the inner wall of the discharge pipe. This structure achieves dual active anti-clogging of the granulator's discharge pipe and the inner wall of the anti-clogging cylinder, avoiding the problem of existing discharge pipes relying solely on manual cleaning and being prone to clogging. It eliminates the need for frequent shutdowns for cleaning, significantly improving production continuity. At the same time, the clamping spring can adapt to discharge pipes with different inner diameters, ensuring that the inner sliding scraper always keeps a tight fit with the inner wall, improving the device's adaptability. It also eliminates the need to customize scrapers for different discharge pipes, reducing operating costs.

[0015] 2. In this utility model, through the mutual cooperation between the C-shaped connecting frame, transmission screw, knob, threaded slide plate, U-shaped clamping plate, and the arc-shaped groove of the anti-blocking cylinder in the connecting assembly, during installation, the anti-blocking cylinder is first slidably fitted onto the outer surface of the granulator discharge pipe, and then the U-shaped clamping plate is rotated around the threaded slide plate, so that the U-shaped clamping plate is inserted into the arc-shaped groove of the anti-blocking cylinder; then, the knob is rotated to drive the transmission screw to rotate, and the transmission screw drives the threaded slide plate to slide upward along the inner wall of the C-shaped connecting frame, and the threaded slide plate generates an upward tension force on the U-shaped clamping plate, so that the U-shaped clamping plate is tightly engaged with the arc-shaped groove, and finally the anti-blocking cylinder and the discharge pipe are firmly fixed; during disassembly, the knob is rotated in the opposite direction, and the transmission screw drives the threaded slide plate to rotate upward. The sliding plate moves down, releasing the tension on the U-shaped clamping plate. Then, the U-shaped clamping plate is rotated out of the arc-shaped groove, allowing the anti-blocking cylinder to be removed from the discharge pipe. This connection structure eliminates the shortcomings of existing components that cannot be disassembled by welding when adding parts to the discharge pipe, and the easy loosening of a single bolt. Through a two-step operation of first clamping and then tightening, the connection stability between the anti-blocking cylinder and the discharge pipe is ensured, and quick disassembly and assembly are achieved by turning the knob. The operation is convenient and facilitates later maintenance. The three ring array connection components cooperate with the arc-shaped groove to ensure that the anti-blocking cylinder is subjected to uniform force and is not prone to displacement in the vibration environment of the granulator. This avoids the problem of reduced anti-blocking effect or material leakage due to loose connection, ensuring stable operation of the device. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution: including a granulator discharge pipe 1, three connecting components 2 are arranged in an annular array on the outer surface of the granulator discharge pipe 1, and an anti-blocking cylinder 3 is slidably sleeved at the bottom of the outer surface of the granulator discharge pipe 1. The connecting components 2 include a C-shaped connecting frame 21, which is fixedly connected to the outer surface of the granulator discharge pipe 1. A transmission screw 22 is rotatably connected to the middle of the C-shaped connecting frame 21. The top end of the transmission screw 22 extends through to the top of the C-shaped connecting frame 21 and is fixedly connected to a knob 23. A threaded sliding plate 24 is threadedly connected to the outer surface of the transmission screw 22. The outer surface of the threaded sliding plate 24 is slidably connected to the inner surface of the C-shaped connecting frame 21. A U-shaped clamping plate 25 is rotatably connected to the left and right ends of the threaded sliding plate 24. Three arc-shaped slots 31 are arranged in an annular array at the top of the outer surface of the anti-blocking cylinder 3. The U-shaped clamping plate 25 is rotatably clamped to the inner surface of the arc-shaped slots 31.

[0024] The overall effect of Embodiment 1 is as follows: by cooperating with the arc-shaped groove 31 of the anti-blocking cylinder 3 through the connection components 2 of the three annular array, a stable connection between the anti-blocking cylinder 3 and the discharge pipe 1 of the granulator is achieved. During installation, the anti-blocking cylinder 3 is first slidably fitted onto the outer surface of the discharge pipe 1 of the granulator. The U-shaped clamping plate 25 is rotated to make it engage with the arc-shaped groove 31. Then, the knob 23 is rotated to drive the transmission screw 22 to rotate, driving the threaded slide plate 24 to slide up along the inner wall of the C-shaped connecting frame 21 and generate a tension force on the U-shaped clamping plate 25, ensuring that the U-shaped clamping plate 25 and the arc-shaped groove 31 are tightly engaged, preventing the anti-blocking cylinder 3 from shifting when the granulator vibrates. During disassembly, the knob 23 is rotated in the opposite direction to move the threaded slide plate 24 down, and after releasing the tension force, the U-shaped clamping plate 25 can be turned out to remove the anti-blocking cylinder 3. The operation is convenient and does not require welding or a single bolt fixation, reducing maintenance costs and improving connection stability.

[0025] Example 2: As Figure 3 and Figure 4 As shown, this utility model provides a technical solution: an annular groove is formed in the middle of the inner surface of the anti-clogging cylinder 3. A drive motor 32 is fixedly connected to the front side of the outer surface of the anti-clogging cylinder 3. The output shaft of the drive motor 32 passes through the interior of the annular groove and is fixedly connected to a drive gear 33. A driven gear ring 34 is meshed with the outer surface of the drive gear 33. An annular rotating plate 35 is fixedly connected to the inner surface of the driven gear ring 34. The annular rotating plate 35 is rotatably connected to the middle of the inner surface of the anti-clogging cylinder 3. Six unblocking components 36 are fixedly connected in an annular array on the inner side of the annular rotating plate 35. The unblocking components 36 include an outer fixed scraper 361, which is fixedly connected to the inner surface of the annular rotating plate 35. The outer side of the outer fixed scraper 361 is in contact with the inner surface of the anti-clogging cylinder 3. A connecting slide plate 362 is fixedly connected to the inner side of 61. An inner sliding scraper 363 is provided on the outer surface of the connecting slide plate 362. The outer side of the inner sliding scraper 363 is in contact with the inner surface of the granulator discharge pipe 1. A connecting groove is provided at the bottom of the outer side of the inner sliding scraper 363. The connecting slide plate 362 passes through the interior of the connecting groove and is fixedly connected to a sliding pressure plate 364. A horizontally penetrating guide post 365 is slidably connected to both the upper and lower ends of the sliding pressure plate 364. The two guide posts 365 are fixedly connected to the upper and lower sides of the inner wall of the connecting groove, respectively. A clamping spring 366 is provided on the outer surface of the guide post 365. One end of the clamping spring 366 is fixedly connected to the side of the sliding pressure plate 364 near the connecting slide plate 362, and the other end of the clamping spring 366 is fixedly connected to the inner wall of the connecting groove.

[0026] The overall effect of Embodiment 2 is as follows: Power is provided by the drive motor 32, which drives the active gear 33 to rotate and mesh with the driven gear ring 34, causing the annular rotating plate 35 to rotate stably within the annular groove of the anti-blocking cylinder 3, thereby driving the six unblocking components 36 to rotate synchronously. In the unblocking components 36, the outer fixed scraper 361 rotates against the inner wall of the anti-blocking cylinder 3, effectively scraping away material adhering to the inner wall of the anti-blocking cylinder 3 in real time, preventing blockage inside the anti-blocking cylinder 3; the inner sliding scraper 363, under the elastic force of the tightening spring 366, moves through... The sliding pressure plate 364 slides along the guide column 365, always closely adhering to the inner wall of the granulator discharge pipe 1. As it rotates with the annular rotating plate 35, it simultaneously removes the sticky material from the inner wall of the granulator discharge pipe 1, achieving double anti-clogging. At the same time, the clamping spring 366 can adaptively adjust the position of the inner sliding scraper 363 according to the inner diameter of the granulator discharge pipe 1, eliminating the need to customize scrapers for discharge pipes with different inner diameters, improving the adaptability of the device. Furthermore, the scraper rotation cleaning does not require manual disassembly, avoiding damage to the inner wall of the discharge pipe due to tool scraping, and extending the service life of the equipment.

[0027] The working principle of the whole equipment is as follows: Before use, the anti-blocking cylinder 3 is slidably sleeved on the bottom of the outer surface of the granulator discharge pipe 1. The U-shaped clamping plate 25 in the connecting assembly 2 is rotated so that it is inserted into the arc-shaped clamping groove 31 on the outer surface of the anti-blocking cylinder 3. Then, the knob 23 is rotated to drive the transmission screw 22 to rotate, which drives the threaded slide plate 24 to slide upward along the inner wall of the C-shaped connecting frame 21, generating an upward tension force on the U-shaped clamping plate 25, so that the anti-blocking cylinder 3 is firmly connected to the granulator discharge pipe 1.

[0028] When the granulator is working, the drive motor 32 on the outer surface of the anti-blocking cylinder 3 is started. The output shaft of the drive motor 32 drives the drive gear 33 to rotate. The drive gear 33 meshes and drives the driven gear ring 34 to rotate. The driven gear ring 34 drives the annular rotating plate 35 to rotate in the annular groove of the anti-blocking cylinder 3. The annular rotating plate 35 then drives the six unblocking components 36 on the inner side to rotate synchronously.

[0029] During the rotation of the unblocking component 36, the outer fixed scraper 361 adheres to the inner wall of the anti-blocking cylinder 3 to scrape away the internal deposits, while the inner sliding scraper 363 adheres to the inner wall of the granulator discharge pipe 1 under the elastic force of the top spring 366, simultaneously scraping away the sticky material on the inner wall of the granulator discharge pipe 1 to prevent material accumulation and blockage. When maintenance or replacement of parts is required, the knob 23 is rotated in the opposite direction to move the threaded slide plate 24 down, releasing the tension on the U-shaped clamping plate 25. After the U-shaped clamping plate 25 is rotated out, the anti-blocking cylinder 3 can be removed from the granulator discharge pipe 1. The operation is convenient and does not affect the main structure of the granulator.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
