Description

Technical Field

[0001] This utility model relates to the field of ring coolers, specifically an automatic variable speed ring cooler blower. Background Technology

[0002] In industries such as metallurgy and chemical engineering, the ring cooler blower is a key piece of equipment in the cooling process, undertaking the important task of providing cooling airflow to materials. Its performance directly affects production efficiency and product quality.

[0003] Currently, traditional ring-cooled blower equipment suffers from numerous problems. On the one hand, the equipment's structural design is not reasonable enough. The materials used for components such as the base and casing of some blowers are not strong enough to withstand the complex loads during long-term operation, making them prone to deformation or even damage. This results in poor equipment stability and a short service life. Furthermore, the equipment's sealing is inadequate, making internal parts susceptible to corrosion from the external environment, increasing maintenance costs and frequency. On the other hand, in terms of blower functionality, most blowers are driven by ordinary motors, which cannot flexibly adjust the wind speed according to actual working conditions, making it difficult to meet diverse production needs. The aerodynamic design of components such as impellers and fan plates is imperfect, resulting in high airflow resistance and low blower efficiency. In addition, existing blowers have significant deficiencies in daily maintenance. Dust easily accumulates on components such as impellers and fan plates after long-term use, affecting the blower effect. However, the cleaning process is usually cumbersome, often requiring shutdown and disassembly of parts, which not only consumes a lot of time and manpower but also reduces production efficiency, leading to economic losses for enterprises. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic variable wind speed annular cooler blower.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an automatic variable speed annular cooler blower, including a base, a transmission component fixed on one side of the top of the base, a blower housing fixed on the other side of the top of the base, an impeller rotatably connected inside the blower housing, multiple air plates fixed inside the impeller, a support shaft inserted into one side wall of the impeller, a support component provided on the outer wall of the support shaft, a connecting pipe rotatably connected inside the support shaft, an air supply pipe inserted into the other end of the connecting pipe, and an air supply pipe clamp provided on the outer wall of the air supply pipe.

[0006] Furthermore, the interior of the impeller and the air vane is hollow to form an air duct, and the air duct of the air vane is connected to the air duct of the impeller.

[0007] Furthermore, the hollow interior of the support shaft forms an air intake channel, which is connected to the air duct inside the impeller.

[0008] Furthermore, the transmission assembly includes a motor, which is fixed on the top side of the base away from the blower housing. A transmission belt is fixed to the output end of the motor, and the other end of the transmission belt is connected to the impeller.

[0009] Furthermore, the outer wall of the connecting pipe is fixed with an annular protrusion, and the connecting pipe is rotatably connected to the support shaft through the annular protrusion.

[0010] Furthermore, the support assembly includes a bearing frame, which is rotatably connected to the outer wall of the support shaft. A bracket is fixed to the end of the bearing frame, which is inserted into and connected to the connecting pipe. The bracket is also fixedly connected to the blower housing and the air supply pipe clamp, respectively.

[0011] The beneficial effects of this utility model are:

[0012] Superior blower performance: The impeller is made of lightweight, high-strength aluminum alloy and features a special curved surface design. The smooth surface of the internal arc-shaped air vane greatly improves aerodynamic efficiency, reduces airflow resistance, and ensures that outside air entering the equipment can be efficiently accelerated within the air duct, thereby outputting a strong and stable airflow and achieving efficient blower function.

[0013] Easy cleaning and maintenance: The impeller and the inner wall of the fan plate are machined with micro air holes, which are connected to the internal air duct. When dust needs to be cleaned, high-pressure gas enters the internal air duct of the impeller and the fan plate through the air supply pipe, connecting pipe, and air intake of the support shaft. It is then sprayed out from the micro air holes to blow away the dust on the outer wall. Cleaning and maintenance can be completed without disassembling the impeller and other parts, ensuring continuous and efficient operation of the equipment, reducing downtime for maintenance, and improving production efficiency.

[0014] Strong overall stability: The connecting pipe is rotatably connected to the support shaft through the annular convex rib, which can not only ensure the stability of the support shaft rotation, but also realize the high-pressure gas transmission. The bracket in the support assembly connects the connecting pipe, blower housing and gas transmission pipe clamp into a stable whole, effectively preventing the displacement of each component during equipment operation and ensuring the stability and reliability of equipment operation.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] See Figures 1-5 This is a schematic diagram of the structure of an automatic variable speed annular cooler blower, including a base 1. The base 1 is made of high-strength alloy steel casting, possessing good compressive strength and stability, and can withstand various loads during equipment operation. A transmission component is fixed to one side of the top of the base 1, and a blower housing 4 is fixed to the other side of the top of the base 1. The blower housing 4 is a closed metal shell made of stainless steel, which not only effectively prevents internal parts from being corroded by the external environment, but also reduces operating noise to a certain extent. An impeller 5 is rotatably connected inside the blower housing 4. The impeller 5 is the blower mechanism. The core component of the device is made of lightweight but high-strength aluminum alloy. Its special curved surface design helps to improve aerodynamic efficiency. Multiple air vanes 6 are fixed inside the impeller 5. The air vanes 6 are evenly distributed inside the impeller 5 and adopt an arc-shaped structure design. The surface is specially smoothed to reduce airflow resistance. Furthermore, micro-pores are machined inside the outer walls of the air vanes 6 and the impeller 5. The hollow interiors of the impeller 5 and the air vanes 6 form air ducts. The air ducts of the air vanes 6 are connected to the air ducts of the impeller 5, thus forming a complete airflow channel, providing a smooth path for cleaning dust from the outer walls of the impeller 5 and the air vanes 6.

[0023] A support shaft 7 is inserted into one side wall of the impeller 5. The support shaft 7 is a hollow cylindrical metal rod made of high-strength alloy steel, which has good rigidity and wear resistance. The outer wall of the support shaft 7 is equipped with a support assembly. The hollow interior of the support shaft 7 forms an air intake channel, which is connected to the air duct inside the impeller 5, so that the high-pressure gas used for cleaning can smoothly enter the impeller for the cleaning process.

[0024] The transmission assembly includes a motor 2, which is fixed on the top side of the base 1 away from the blower housing 4. The motor 2 is a high-performance variable frequency motor that can flexibly adjust the speed according to actual needs, thereby realizing the automatic variable wind speed function of the blower equipment. A transmission belt 3 is fixed to the output end of the motor 2. The transmission belt 3 is made of high-quality rubber material with a special anti-slip treatment on the surface, which has good transmission efficiency and a long service life. The other end of the transmission belt 3 is connected to the impeller 5. The power of the motor 2 is transmitted to the impeller 5 through the transmission belt 3, driving the impeller 5 to rotate at high speed.

[0025] The other end of the connecting pipe 10 is connected to an air supply pipe 11, which is connected to a high-pressure air pump. The air supply pipe 11 is used to deliver high-pressure gas for cleaning dust from the outer wall of the impeller 5 and the air plate 6 to a designated location. An air supply pipe clamp 12 is provided on the outer wall of the air supply pipe 11. The air supply pipe clamp 12 consists of two metal plates and is fastened to the outer wall of the air supply pipe 11 by bolts. It serves to fix and protect the air supply pipe 11 and prevent the air supply pipe 11 from being displaced or damaged under airflow pressure.

[0026] The outer wall of the connecting pipe 10 is fixed with an annular protrusion. The connecting pipe 10 is rotatably connected to the support shaft 7 through the annular protrusion. The design of the annular protrusion can prevent the support shaft 7 from shifting during rotation, ensuring that the support shaft 7 remains stable during rotation. At the same time, high-pressure gas is delivered to the support shaft 7 and then to the air duct of the impeller 5 through the support shaft 7.

[0027] The support assembly includes a bearing frame 9, which is made of high-strength cast iron and has a high-precision rolling bearing installed inside. This effectively reduces the friction when the support shaft 7 rotates. The bearing frame 9 is rotatably connected to the outer wall of the support shaft 7. A bracket 8 is fixed to the end of the bearing frame 9. The bracket 8 is a metal frame structure with good support strength. The bracket 8 is inserted into the connecting pipe 10 and fixedly connected to the blower housing 4 and the air supply pipe clamp 12, respectively. The bracket 8 connects the connecting pipe 10, the blower housing 4, and the air supply pipe clamp 12 into a stable whole, ensuring the stability of the equipment during operation.

[0028] When using this utility model:

[0029] When the automatic variable speed annular cooler blower is running, it first starts the blower operation. The high-performance variable frequency motor 2 is installed on the side of the base 1 away from the blower housing 4. Its output end is connected to the impeller 5 through a specially treated anti-slip rubber transmission belt 3. The motor 2 adjusts the speed according to actual needs and transmits power to the impeller 5 through the transmission belt 3, driving the impeller 5 to rotate at high speed. The impeller 5 is made of lightweight high-strength aluminum alloy. Its special curved surface design improves aerodynamic efficiency. The smooth surface of the evenly distributed arc-shaped air plates 6 inside reduces airflow resistance. Outside air enters through the air inlet of the blower housing 4. As the impeller 5 rotates, the air is accelerated in the air duct and output through the air outlet of the blower housing 4 to realize the blower function.

[0030] When it is necessary to clean the dust on the outer wall of the impeller 5 and the fan plate 6, the cleaning process is started. The air supply pipe 11 is connected to the high-pressure air pump, and high-pressure gas is transported through the air supply pipe 11. The air supply pipe clamp 12 on the outer wall of the air supply pipe 11 plays a role in fixing and protecting it, preventing the air supply pipe 11 from being displaced or damaged due to airflow pressure. The annular protrusion on the outer wall of the connecting pipe 10 is rotatably connected to the support shaft 7, which on the one hand ensures the stability of the rotation of the support shaft 7, and on the other hand introduces the high-pressure gas into the air intake of the support shaft 7. The high-pressure gas enters the air duct inside the impeller 5 and the fan plate 6 along the air intake. Since the outer wall of the fan plate 6 and the impeller 5 is machined with micro air holes, the high-pressure gas is sprayed out from these micro air holes to blow and clean the outer wall of the impeller 5 and the fan plate 6, cleaning the attached dust. The cleaned dust is discharged with the airflow, completing the cleaning and maintenance of the impeller 5 and the fan plate 6, ensuring the continuous and efficient operation of the equipment.
