Description

Technical Field

[0001] This utility model relates to the field of alloy impeller technology, and in particular to a wear-resistant and corrosion-resistant alloy impeller. Background Technology

[0002] As a general-purpose mechanical device widely used in many fields, the impeller, a core component of the fan, plays a crucial role in converting the mechanical energy of the motor into the kinetic and potential energy of the gas. In industrial production, the fan impeller in the ventilation system is responsible for delivering fresh air to the workshop and expelling harmful gases, ensuring a safe and comfortable production environment. In thermal power plants, the impellers of induced draft fans and forced draft fans ensure the air supply required for boiler combustion and the emission of exhaust gases after combustion, which is essential for the stable operation of the power generation process. In chemical production plants, the fan impeller participates in multiple stages such as material conveying and reaction gas circulation, and is a key factor in maintaining the smooth flow of chemical processes. Therefore, it is necessary to design a wear-resistant and corrosion-resistant alloy impeller.

[0003] Existing alloy impellers are often found in industrial production environments with high levels of dust. When the fan is operating, the dust-laden airflow impacts the impeller surface at high speed, causing intense friction and collisions between dust particles and the impeller material. Continuous wear will gradually thin the impeller blades and increase surface roughness, leading to a decrease in fan airflow and pressure, and reduced efficiency. Long-term wear may also cause blade breakage, resulting in fan failure and severely affecting the continuity of production. Furthermore, existing fan impellers generate intense friction with the surrounding gas during high-speed rotation. As the rotational speed increases and the operating time lengthens, the impeller temperature will continuously rise. Excessive temperature will reduce the mechanical properties of the impeller material, such as strength and hardness, making the impeller more prone to wear and deformation, thus affecting its normal operation. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant and corrosion-resistant alloy impeller to solve the problems mentioned in the background art. In many industrial production environments, there is a large amount of dust. When the fan is working, the dust-laden airflow impacts the impeller surface at high speed, causing strong friction and collision between dust particles and the impeller material. Continuous wear will gradually thin the impeller blades and increase surface roughness, leading to a decrease in fan airflow and pressure, reduced efficiency, and long-term wear may even cause blade breakage, resulting in fan failure and seriously affecting the continuity of production. Furthermore, existing fan impellers generate strong friction with the surrounding gas when rotating at high speed. As the rotation speed increases and the operating time lengthens, the impeller temperature will continuously rise. Excessive temperature will reduce the mechanical properties of the impeller material, such as strength and hardness, making the impeller more prone to wear and deformation, affecting its normal operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant and corrosion-resistant alloy impeller, comprising an impeller, an impeller ring mounted on the right side of the impeller, a dustproof mechanism threaded around the outer periphery of the impeller ring, a cooling mechanism mounted on the back of the impeller, the dustproof mechanism comprising a dustproof frame threaded around the outer periphery of the impeller ring, a protective net mounted on the top surface of the dustproof frame, a filter frame mounted on the rear end of the dustproof frame, and a fixing plate mounted on the back of the fixing plate, a cooling plate mounted on the back of the cooling plate, and a cooling base mounted on the back of the cooling plate.

[0006] As a further embodiment of this utility model, a fixing ring is fixedly connected to the outer periphery of the blade ring, and several fixing holes are opened around the fixing ring. The fixing ring facilitates the installation of the dustproof mechanism.

[0007] As a further embodiment of this utility model, a fixing plate is connected to the internal thread of the fixing hole, and several threaded holes are opened around the fixing plate. The fixing plate serves to connect and fix the dustproof mechanism.

[0008] As a further embodiment of this utility model, the internal thread of the threaded hole is connected to a fixing bolt, and the external thread of the end of the fixing bolt is connected to the inside of the fixing hole of the fixing ring. The fixing bolt serves to fix the thread in the middle.

[0009] As a further embodiment of this utility model, the cooling plate has a hollowed-out cooling grid inside, and a cooling ring is installed on the right side of the cooling base. The hollowed-out partition creates space at the bottom support for heat dissipation and cooling.

[0010] As a further embodiment of this utility model, the cooling base has a cooling channel inside, the cooling channel is filled with coolant, and a liquid inlet is installed on the top surface of the cooling base. The liquid inlet is threaded with a cap. The cooling channel helps to cool the inside of the cooling base and maintain the stable operation of the device.

[0011] As a further embodiment of this utility model, a connector is fixedly connected to the middle right side of the fixing plate. The connector has a through hole inside, which facilitates the installation of the rotating impeller through the through hole.

[0012] This utility model provides a wear-resistant and corrosion-resistant alloy impeller, which has the following beneficial effects:

[0013] 1. This wear-resistant and corrosion-resistant alloy impeller, through the dustproof mechanism, requires the dustproof frame to be tightened together with the fixing bolts, using the fixing rings and fixing plates around the perimeter of the frame. The protective netting on the top surface of the dustproof frame prevents large impurities from entering the blades. Next, a filter frame is installed inside the rear of the dustproof frame, blocking and collecting smaller impurities to prevent them from entering the blades and causing frictional damage. This protects the blades and avoids strong friction and collision between dust particles and the impeller material, which would cause the impeller blades to gradually thin and the surface roughness to increase, leading to a decrease in airflow and pressure, and reduced efficiency. Long-term wear could also cause blade breakage, resulting in fan malfunction and severely affecting the continuity of production.

[0014] 2. This wear-resistant and corrosion-resistant alloy impeller, through the setting of a cooling mechanism, addresses the issue that during device operation, prolonged fan rotation can generate heat in the impeller, potentially leading to overheating and damage. Therefore, a cooling plate is installed on the back of the impeller, with perforated cooling grids inside for heat dissipation. Furthermore, a cooling ring and cooling base are installed behind the cooling plate, with coolant filling the internal cooling channels through the liquid inlet on the top surface of the cooling base, simultaneously cooling the impeller. This effectively cools the impeller, preventing its temperature from continuously rising with increasing rotational speed and operating time. Excessive temperature can reduce the mechanical properties, strength, and hardness of the impeller material, making it more prone to wear and deformation, thus affecting its normal operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a wear-resistant and corrosion-resistant alloy impeller, including an impeller 1, an impeller ring 2 installed on the right side of the impeller 1, a dustproof mechanism 3 threadedly connected to the outer periphery of the impeller ring 2, a cooling mechanism 4 installed on the back of the impeller 1, the dustproof mechanism 3 including a dustproof frame 301 threadedly connected to the outer periphery of the impeller ring 2, a protective net 302 installed on the top surface of the dustproof frame 301, a filter frame 303 installed at the rear end of the dustproof frame 301, and a cooling mechanism 4 including a fixing plate 401 installed on the back of the impeller 1, a cooling plate 402 installed on the back of the fixing plate 401, and a cooling base 403 installed on the back of the cooling plate 402.

[0022] Please see Figure 2 A fixing ring 5 is fixedly connected to the outer periphery of the blade ring 2. Several fixing holes are opened around the fixing ring 5. The fixing ring 5 facilitates the installation of the dustproof mechanism 3.

[0023] Please see Figure 2 The fixing hole has a fixing plate 6 connected to the internal thread. The fixing plate 6 has several threaded holes around its perimeter. The fixing plate 6 serves to connect and fix the dustproof mechanism 3.

[0024] Please see Figure 2 The threaded hole has a fixing bolt 7 inside, and the external thread of the end of the fixing bolt 7 is connected to the fixing hole of the fixing ring 5. The fixing bolt 7 serves to fix the middle thread.

[0025] Please see Figure 3 The cooling plate 402 has a hollowed-out cooling grid inside, and the cooling base 403 has a cooling ring 8 installed on the right side. The hollowed-out partition creates space at the bottom support for heat dissipation and cooling.

[0026] Please see Figure 3 The cooling base 403 has a cooling channel inside, which is filled with coolant. The top surface of the cooling base 403 is equipped with a liquid inlet 9, and the inside of the liquid inlet 9 is threaded with a cap 10. The cooling channel helps to cool the inside of the cooling base 403 and maintain the stable operation of the device.

[0027] Please see Figure 1A connector 11 is fixedly connected to the middle right side of the fixing plate 401. The connector 11 has a through hole inside, which facilitates the installation of the rotating impeller 1 through the through hole.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: First, use the fixing bolts 7 to connect the dustproof frame 301 with the fixing rings 5 ​​and fixing pieces 6 around it and tighten them with threads to install it together. Since the top surface of the dustproof frame 301 is equipped with a protective net 302, it can prevent large impurities from entering the blades. Then, a filter frame 303 is installed inside the rear of the dustproof frame 301. The filter frame 303 blocks and collects smaller impurities, preventing impurities from entering the blades and causing friction damage to the blades.

[0030] The second step: Due to the prolonged fan rotation, the impeller 1 will generate heat, which may cause it to overheat and damage the impeller 1. Therefore, a cooling plate 402 is installed on the back of the impeller 1 to cool it down. The cooling plate 402 has a hollow cooling grid inside, which dissipates heat and cools down through the hollow space. Since a cooling ring 8 and a cooling base 403 are installed on the back of the cooling plate 402, coolant is filled into the internal cooling channel through the liquid inlet head 9 on the top surface of the cooling base 403 to cool down simultaneously.
