Description

Technical Field

[0001] This utility model relates to the field of biological pelleting, and more specifically, it relates to a biological pelleting machine with an adjustable filter screen. Background Technology

[0002] Existing bio-granulator technology has certain drawbacks in the structural design and installation of the filter system. The main problem is that the filter replacement is extremely inconvenient, and it is impossible to achieve quick and efficient disassembly and installation, which affects the ease of operation and production continuity. Traditional pelletizer filters generally use traditional installation methods such as bolt fixing, snap locking, or welding connection. Although these methods can ensure stability and sealing during operation, they bring operational difficulties when replacing or cleaning them.

[0003] Existing filter installation locations are typically designed inside equipment or in confined spaces, requiring operators to perform complex disassembly and assembly operations within limited workspaces. This not only increases labor intensity but also poses safety hazards, especially in high-temperature conditions or when residual materials are present, making the operating environment even more challenging. The filter specifications and pore size adjustment capabilities are limited, requiring the preparation of multiple sets of filters of different specifications for replacement. Each adjustment necessitates a tedious disassembly and assembly process, hindering rapid adjustments to production processes and severely impacting production efficiency and product quality control flexibility.

[0029] It also includes a quick-release mechanism, which includes a fixed cylinder 21. The outer wall of the filter cylinder 14 is provided with four sets of fixed cylinders 21. Multiple sets of elastic plates 22 are provided inside the fixed cylinders 21. Multiple sets of push springs 23 are provided inside the fixed cylinders 21. The other end of the push spring 23 is connected to a push ring 24. The push ring 24 is slidably connected to the fixed cylinder 21. Multiple sets of clamping plates 25 are slidably connected inside the fixed cylinder 21. Spacing grooves 26 are formed between the multiple sets of clamping plates 25. One end of the clamping plate 25 is connected to a circular plate 27. Multiple sets of plates corresponding to the elastic plates 22 are formed on the surface of the clamping plate 25. The card slot 28 and the side wall of the circular plate 27 are provided with a compression spring 29. The other end of the compression spring 29 is connected to a plug rod 210. The plug rod 210 is slidably connected to the fixed cylinder 21. The other end of the plug rod 210 is adapted to the slot 113. A pressure ring 211 is abutted and connected to the bottom of the circular plate 27. Multiple sets of sliding plates 212 are connected to the lower end face of the pressure ring 211. The sliding plates 212 are embedded in the spacer groove 26 and slidably connected to the card plate 25. The other end of the sliding plate 212 is connected to an arc ring 213. The arc ring 213 is located in the fixed cylinder 21 and is adapted to the elastic plate 22.

[0030] When the device is working, the material is first conveyed into the filter cylinder 14, the motor 12 is started, the motor 12 drives the driven wheel 16 to rotate through the belt 17, the rotating shaft 15 connected to the driven wheel 16 rotates accordingly, the rotating shaft 15 drives the discharge roller 18 connected to its other end to rotate together, the material falls below the filter screen 112 after being filtered by the filter screen 112, the discharge roller 18 cooperates with the discharge plate 19 to crush the falling material, and then falls into the inclined plate 110 through the discharge plate 19, and finally is discharged through the discharge port 111;

[0031] Under normal conditions, the elastic sheet 22 is engaged in the slot 28 to fix the insert rod 210. The insert rod 210 is inserted into the slot 113 on the surface of the filter screen 112 to fix the filter screen 112. When the filter screen 112 needs to be replaced, the operator manually presses the pressure ring 211. The pressure ring 211 moves the arc ring 213 downward through the sliding plate 212. The arc ring 213 squeezes the elastic sheet 22, causing the elastic sheet 22 to expand outward and disengage from the slot 28, thereby releasing the fixation of the insert rod 210. At this time, the elastic sheet 22 is engaged in the groove on the outer surface of the arc ring 213. Then, pull the circular plate 27 outward. The circular plate 27 moves the insert rod 210 outward through the compression spring 29, thereby releasing the fixation of the insert rod 210 to the slot 113 and releasing the old filter screen 112. Then, move the pressure ring 211 upward. The elastic piece 22 is disengaged from the arc ring 213. Then, the four sets of quick-release mechanisms are released sequentially to remove the old filter screen 112. When a new filter screen 112 needs to be installed, the new filter screen 112 is placed in the target position. The circular plate 27 is pressed to slide into the fixed cylinder 21. The circular plate 27 drives the insertion rod 210 and the locking plate 25 to move inward synchronously. When the locking groove 28 on the surface of the locking plate 25 moves to the position of the elastic piece 22, the elastic piece 22 is locked into the locking groove 28 again. The insertion rod 210 is also inserted into the slot 113 of the new filter screen 112. The push spring 23 provides an upward push force to the push ring 24, and the push ring 24 provides an upward push force to the locking plate 25, so that the elastic piece 22 and the inner bottom of the locking groove 28 are tightly abutted, thereby realizing the locking and fixing of the insertion rod 210 and the slot 113. The new filter screen 112 is installed.
