Description

Technical Field

[0001] This utility model belongs to the technical field of straw production equipment, specifically relating to a contamination prevention device for a straw production cooling device. Background Technology

[0002] In straw manufacturing, the cooling system is a crucial element in ensuring product quality and production efficiency. Current straw production cooling systems primarily employ a combination of air and water cooling. By precisely controlling the temperature, flow rate, and duration of the cooling medium, rapid and uniform cooling and shaping of straws made of various materials such as PP, PET, and PLA are achieved. Modern cooling systems are typically equipped with multi-stage temperature control modules that automatically adjust the cooling intensity based on the straw diameter and extrusion speed, preventing deformation or internal stress issues caused by uneven cooling. Regarding hygiene, the system utilizes food-grade stainless steel and a closed design, combined with a HEPA filtration system and UV sterilization module to effectively control the cleanliness of the production environment. An advanced intelligent control system monitors the temperature curve and product status in real time during the cooling process, ensuring that straw dimensional stability and surface finish meet industry standards.

[0003] In the anti-fouling system of the straw production cooling device, the air inlet filter plate is a key component that prevents external dust and impurities from entering the cooling channel. Over time, large amounts of dust and impurities tend to accumulate on the surface of the filter plate, affecting the airflow efficiency. Current technology mainly relies on manual cleaning after machine shutdown. Operators need to disassemble the filter plate and then blow it with compressed air or clean it with a brush. The cleaning operation is cumbersome, inconvenient, and inefficient. At the same time, dust is easily scattered during the cleaning process, which can easily cause secondary dust pollution.

[0018] See attached document Figure 1-5A contamination prevention device for a straw production cooling apparatus includes an air inlet duct 3, a dust filter plate 5 fixed at the port of the air inlet duct 3, an internal plate 6 inside the air inlet duct 3, a connecting pipe 9 rotatably connected to the center of the internal plate 6, a cleaning disc 7 fixed on the connecting pipe 9 located on one side of the dust filter plate 5, multiple equidistant ventilation holes 8 through the side of the cleaning disc 7, a cleaning component 1 inside the cleaning disc 7 for cleaning dust from the dust filter plate 5, and a rotating component 2 inside the air inlet duct 3 for rotating the cleaning disc 7. In use, cold air from the outside environment is filtered through the dust filter plate 5 and flows into the air inlet duct 3 through the multiple ventilation holes 8 on the cleaning disc 7. The air inlet duct 3 then delivers the cold air to the cooling apparatus to cool the straws. During this process, the dust filter plate 5... 5. The filter plate 5 filters and intercepts solid particulate impurities in the air. After prolonged use, a large amount of dust and impurities accumulate on the sides of the filter plate 5, causing some blockage to the filter holes and affecting the airflow rate. When the filter plate 5 needs to be cleaned, the set adjustment component 2 drives the cleaning disc 7 to rotate, thereby brushing the sides of the filter plate 5 through the rotating cleaning disc 7. The set cleaning component 1 sucks away the dust and impurities brushed from the filter plate 5, avoiding dust flying around during cleaning and preventing secondary pollution of the filter plate 5 and the air inlet duct 3. This effectively improves the cleaning effect of the filter plate 5, increases the overall cleaning efficiency, and eliminates the need for manual cleaning of the filter plate 5, saving manpower and effectively reducing the cleaning workload.

[0019] Further as Figure 2 , Figure 3 and Figure 5 As shown, it is worth noting that the cleaning component 1 includes an inner cavity 103 inside the cleaning circular plate 7. The inner cavity 103 is connected to the connecting pipe 9. The cleaning circular plate 7 has a suction hole 101 on its side near the dust filter plate 5, which communicates with the inner cavity 103. The end of the connecting pipe 9 is rotatably connected to a suction pipe 104, which communicates with the inner cavity 103. Multiple suction holes 101 are provided and are evenly distributed. The suction pipe 104 is connected to a dust collector. A negative pressure is formed between the suction pipe 104 and the inner cavity 103, thereby suctioning and removing the dust and impurities brushed off the dust filter plate 5 through the multiple suction holes 101. This avoids dust flying everywhere during cleaning and prevents secondary pollution of the dust filter plate 5 and the inside of the air inlet duct 3 caused by flying dust and impurities. This effectively improves the cleaning effect of the dust filter plate 5, increases the overall cleaning efficiency, and eliminates the need for manual cleaning of the dust filter plate 5, saving manpower and effectively reducing the cleaning workload.

[0020] Further as Figure 3 and Figure 4As shown, it is worth noting that the cleaning disc 7 is provided with densely distributed bristles 102 on the side near the dust filter plate 5, and the bristles 102 are in contact with the side of the dust filter plate 5. In actual operation, when the cleaning disc 7 rotates, the bristles 102 on the cleaning disc 7 brush the side of the dust filter plate 5, thereby efficiently cleaning the filter holes on the dust filter plate 5 through the bristles 102.

[0021] Further as Figure 2 and Figure 5 As shown, it is worth noting that the switching assembly 2 includes a drive motor 203 fixed to the side of the built-in plate 6. A second gear 202 is fixed to the output end of the drive motor 203, and a first gear 201 that meshes with the second gear 202 is fixed to the outer wall of the connecting pipe 9. In actual operation, the drive motor 203 is started, and the output end of the drive motor 203 drives the second gear 202 to rotate. In turn, the second gear 202 and the first gear 201 work together to drive the connecting pipe 9 to rotate. This, in turn, drives the cleaning disc 7 to rotate, thereby achieving the brushing and cleaning of the dust filter plate 5.

[0022] This solution has the following working process: Cold air from the external environment is filtered by the dust filter plate 5 and then flows into the air inlet duct 3 through multiple air vents 8 on the cleaning disc 7. The air inlet duct 3 then delivers the cold air to the cooling device to cool the suction pipe. During this process, the dust filter plate 5 filters and intercepts solid particulate impurities in the air. After prolonged use, a large amount of dust and impurities accumulate on the sides of the dust filter plate 5, causing some blockage to the filter holes and affecting the airflow rate. When the dust filter plate 5 needs to be cleaned, the drive motor 203 is started to operate. The output end of 203 drives the second gear 202 to rotate, which in turn drives the connecting pipe 9 to rotate through the cooperation of the second gear 202 and the first gear 201. This, in turn, drives the cleaning disc 7 to rotate through the connecting pipe 9. The bristles 102 on the cleaning disc 7 brush the side of the dust filter plate 5, thereby efficiently cleaning the filter holes on the dust filter plate 5. The dust and impurities brushed off the dust filter plate 5 are then sucked away through multiple suction holes 101, preventing dust from flying around during cleaning and avoiding secondary pollution of the dust filter plate 5 and the inside of the air inlet duct 3 caused by the flying dust and impurities.

[0023] Further as Figure 2 As shown, it is worth noting that a connecting rod 10 is fixed between the built-in plate 6 and the inner wall of the air inlet duct 3. Multiple connecting rods 10 are provided and the multiple connecting rods 10 are distributed in a ring.

[0024] In summary: When cleaning the dust filter plate 5 is required, the rotating component 2 drives the cleaning disc 7 to rotate, thereby brushing the side of the dust filter plate 5. The cleaning component 1 then sucks away the dust and impurities brushed from the dust filter plate 5, preventing dust from flying around during cleaning and avoiding secondary pollution of the dust filter plate 5 and the air inlet duct 3. This effectively improves the cleaning effect of the dust filter plate 5, increases the overall cleaning efficiency, and eliminates the need for manual cleaning of the dust filter plate 5, saving manpower and effectively reducing the cleaning workload.
