Description

Technical Field

[0001] This utility model relates to the field of air-cooled tunnel box technology, specifically a roller conveyor type air-cooled tunnel box. Background Technology

[0002] In the food processing industry, roller conveyor air-cooled tunnel enclosures are widely used, especially in meat processing, where they play a crucial role in ensuring product quality and improving production efficiency. Traditional roller conveyor air-cooled tunnel enclosures mainly consist of an air-cooled enclosure and an air intake mechanism. However, long-term practical application has revealed a series of insurmountable problems.

[0003] While existing air-cooled tunnel enclosures can provide basic air-cooling space and the intake fan can also introduce outside air to form cold air, they have serious technical shortcomings in terms of fine-grained airflow control and conveyor belt cleaning and maintenance. In the airflow guidance stage, traditional air guiding methods are simple and crude, and cannot reasonably distribute and guide the cold air blown out by the intake fan. For example, in meat processing, it is impossible to ensure that the cold air evenly covers every piece of meat, resulting in some meat being over-cooled, affecting the taste and quality, while some meat is under-cooled, which easily breeds microorganisms and reduces the product qualification rate.

[0004] Cleaning and maintaining conveyor belts is a major challenge for traditional equipment. During meat processing, blood, grease, meat scraps, and dust easily adhere to the conveyor belt. Traditional equipment struggles to effectively remove sticky substances and particulate impurities, leading to dirt buildup on the conveyor belt surface. This not only affects equipment operation but also severely contaminates subsequently transported meat, increasing food safety risks. Similarly, conventional cleaning methods cannot thoroughly clean the dust accumulated in the mesh and gaps inside the conveyor belt. Long-term dust accumulation, once mixed into food, will cause product quality problems and economic losses. Utility Model Content

[0005] The purpose of this invention is to provide a roller conveyor type air-cooled tunnel housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes an air-cooled housing and an air intake fan. The air intake fan is fixed to the top of the air-cooled housing, and an air duct is fixed to the bottom of the outer wall of the air intake fan. An air guide plate is fixed to the end of the air duct away from the air intake fan. Multiple first fixing components are fixed to the outer wall of the air guide plate. A cleaning component is fixed to the left outer wall of the air guide plate, and a dust removal component is fixed to the right outer wall of the air guide plate.

[0007] Preferably, the cleaning component includes a first support member, which is fixed to the outer wall of the left side of the air guide plate. A scraper block is fixed to the side of the first support member away from the air guide plate. A second fixing member is fixed to the outer wall of the scraper block. The scraper block is fixed to the bottom of the air-cooled box by the second fixing member.

[0008] Preferably, the dust removal component includes a second support member, which is fixed to the outer wall of the right side of the air guide plate. A brush plate is fixed to the side of the second support member away from the air guide plate. A third fixing member is fixed to the outer wall of the brush plate. The brush plate is fixed to the bottom of the air-cooled box by the third fixing member.

[0009] Preferably, the scraper block is an irregularly shaped block, and the end of the scraper block that contacts the conveyor belt has a protrusion at a certain angle, which can effectively clean the dirt on the surface of the conveyor belt.

[0010] Preferably, the end of the brush plate that contacts the conveyor belt is made of hard bristles, which can effectively remove dust from the conveyor belt.

[0011] Preferably, the conveyor belt at the bottom of the air-cooled box is a mesh conveyor belt, which allows for bottom ventilation and ensures that the material is evenly exposed to air.

[0012] Preferably, the air guide plate has a hollow interior forming a cavity, allowing the air duct to deliver air into the cavity of the air guide plate.

[0013] Preferably, the top of the cavity of the air guide plate is provided with multiple ventilation holes to allow air circulation.

[0014] Preferably, a triangular protrusion is fixed at the bottom of the cavity of the air guide plate. The protrusion enables convection to be generated inside the cavity when cold air enters from both sides of the air guide plate, so that the cold air is ejected from the ventilation hole at the top of the cavity of the air guide plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Uniform airflow to materials: The design of the air duct and air guide plate enables airflow convection within the air-cooled box, ensuring that the materials receive cold air cooling in all directions and evenly. This design guarantees the temperature consistency of the materials during the air-cooling process.

[0017] 2. Conveyor Belt Cleaning: The design of the cleaning component greatly facilitates conveyor belt maintenance. Its angled protrusion at the contact end with the conveyor belt acts like a scraper, efficiently removing spilled sticky substances or particulate impurities during continuous operation, effectively maintaining conveyor belt cleanliness. This not only reduces the frequency of manual cleaning and lowers maintenance costs but also prevents secondary contamination of materials caused by dirt accumulation on the conveyor belt.

[0018] 3. Deep Dust Removal: The dust removal components can thoroughly clean dust adhering to the inside of the conveyor belt. The stiff brushes at the contact point with the conveyor belt, with their elasticity and hardness, can reach deep into the mesh and gaps of the conveyor belt to effectively brush off dust. This design is particularly important in the food production industry, ensuring the cleanliness of the conveyor belt and preventing dust from contaminating the food. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a roller conveyor type air-cooled tunnel box technical solution: including an air-cooled box 1 and an air intake fan 2. The air-cooled box 1 can create a stable space for materials and support the air intake fan 2. The air intake fan 2 is fixed at the top of the air-cooled box 1. The air intake fan 2 can draw in outside air and provide continuous cold air power for the air-cooled box 1, which promotes the rapid flow of air in the box. The bottom of the outer wall of the air intake fan 2 is fixed with an air duct 3. The air duct 3 can divert a part of the cold air blown out by the air intake fan 2. Relying on the pipe structure of the air duct, the diverted cold air is precisely guided by the guide plate and injected into the interior of the air guide plate 4.

[0026] A guide plate 4 is fixed at the end of the air duct 3 away from the air inlet fan 2. The guide plate 4 has a hollow cavity structure inside. The triangular protrusion at the bottom of the cavity of the guide plate 4 can change the direction of the cold air entering from both sides, causing the airflow to generate convection in the cavity and playing a guiding role. Multiple ventilation holes are opened at the top of the guide plate 4. These ventilation holes are arranged in a specific layout. Multiple first fixing members 5 are fixed on the outer wall of the guide plate 4. One end of the first fixing member 5 is fixedly connected to the outer wall of the guide plate 4, and the other end is fixedly connected to the bottom of the air-cooled box 1. The first fixing member 5 provides a stable fixing effect for the guide plate 4.

[0027] A cleaning component is fixed to the left outer wall of the air guide plate 4. The cleaning component can effectively remove dirt attached to the surface of the conveyor belt, thereby reducing maintenance costs. The cleaning component includes a first support member 6, which is firmly connected to the left outer wall of the air guide plate 4 and can provide stable support for the scraper block 7. The scraper block 7 is fixed to the side of the first support member 6 away from the air guide plate 4. The scraper block 7 has an irregular shape and protrudes at a specific angle at the end that is disconnected from the conveyor belt. It can scrape off sticky substances or particulate impurities on the surface of the conveyor belt and effectively maintain the cleanliness of the conveyor belt. A second fixing member 8 is fixed to the outer wall of the scraper block 7. The second fixing member 8 firmly fixes the scraper block 7 to the bottom of the air-cooled box 1, ensuring that the scraper block 7 is stable in position during the cleaning operation and always maintains appropriate contact pressure with the conveyor belt, ensuring that the cleaning work is carried out efficiently.

[0028] A dust removal component is fixed to the right outer wall of the air guide plate 4. The dust removal component can clean the dust adhering to the inside of the conveyor belt and ensure the food safety of the materials. The dust removal component includes a second support member 9, which is fixed to the right outer wall of the air guide plate 4 to provide stable support for the brush plate 10. The brush plate 10 is fixed to the side of the second support member 9 away from the air guide plate 4. The end of the brush plate 10 that contacts the conveyor belt is made of hard bristles. The bristles have a certain degree of elasticity and hardness and can clean the dust adhering to the mesh and gaps of the conveyor belt. A third fixing member 11 is fixed to the outer wall of the brush plate 10. The third fixing member 11 can stably fix the brush plate to the bottom of the air-cooled box 1 to ensure that the position of the brush plate 10 is accurate during the dust removal process and maintain a stable dust removal effect.

[0029] Working Principle: When using a roller-type air-cooled tunnel housing, starting the inlet fan 2 causes the motor to drive the impeller to rotate at high speed. As the impeller rotates, the blades push the air, reducing the air pressure inside the fan and creating a negative pressure zone. Outside air is drawn into the fan under the influence of the atmospheric pressure difference. Subsequently, accelerated by the impeller, it is ejected from the fan outlet as a high-speed airflow. This process dries the material inside the air-cooled housing 1. Due to the design of the duct 3, the airflow is split when ejected from the inlet fan 2, with a portion of the airflow entering the duct of duct 3. The other end is fixedly connected to the air guide plate 4, so the airflow can enter the cavity of the air guide plate 4 through the pipe of the air duct 3. When the airflow enters the cavity of the air guide plate 4, the triangular protrusion fixed at the bottom of the cavity of the air guide plate 4 changes the direction of the airflow entering from both sides, causing the airflow to generate convection in the cavity, making the airflow more uniformly mixed, and finally being stably sprayed out from the ventilation hole at the top of the air guide plate 4. Since the conveyor belt is a mesh conveyor belt, it will not affect the airflow from below to cool the material, thus ensuring that the material in the cold air box 1 receives cold air cooling in all directions and evenly.

[0030] If a sticky object adheres to the outer wall of the conveyor belt while it is transporting materials, the sticky dirt will move to one side of the scraper block 7 as it moves along the conveyor belt. The raised part of the scraper block 7 will fit tightly against the surface of the conveyor belt. The raised part of the scraper block 7, with its shape and fixed position, will scrape the dirt off the surface of the conveyor belt like a scraper, effectively cleaning the conveyor belt. The second fixing part 8 will firmly fix the scraper block 7 to the bottom of the air-cooled box 1, ensuring that the scraper block 7 is stable in position during the cleaning operation and always maintains appropriate contact pressure with the conveyor belt, ensuring that the cleaning work is carried out efficiently.

[0031] During the material transport process, the airflow generated by the air intake fan 2 and the air guide plate 4 may cause dust or impurities to accumulate inside the conveyor belt, especially in the mesh and gaps. When the conveyor belt passes the brush plate 10, the hard brush makes full contact with the surface and internal gaps of the conveyor belt. The brush penetrates the mesh and gaps with its own elasticity and brushes off the dust during the movement of the conveyor belt, achieving efficient removal of dust inside the conveyor belt. The third fixing member 11 stably fixes the brush plate 10 to the bottom of the air-cooled box 1, ensuring that the brush plate 10 is accurately positioned during the process and maintaining a stable dust removal effect.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
