Description

Technical Field

[0001] This utility model relates to the field of material conveying blower technology, and more specifically, to a polyacrylamide material conveying blower. Background Technology

[0002] Polyacrylamide is a linear polymer. It possesses excellent flocculation properties, enabling suspended particles in liquids to coagulate and settle. Therefore, it is widely used in wastewater treatment to effectively remove impurities and pollutants from water. Simultaneously, it plays an important role in numerous industrial sectors, including papermaking for paper reinforcement and retention / filtration aids, and in oil extraction for enhanced oil recovery.

[0003] Polyacrylamide powder requires conveying fans for transport. When conveying polyacrylamide powder in humid conditions, the powder is affected by the moist air, leading to reduced conveying efficiency and sticky conveying pipes. This necessitates larger air volumes and pressures to maintain conveying effectiveness, further increasing energy consumption. Therefore, we propose a polyacrylamide conveying fan.

Detailed Implementation

[0021] like Figures 1 to 6 As shown, this utility model relates to a polyacrylamide conveying blower, including a base 101, a blower body 200 mounted on the base 101, and a drying mechanism 300 installed at the air inlet of the blower body 200. The rear end of the base 101 is provided with an arc-shaped positioning groove 102. The rear end of the base 101 is provided below the positioning groove 102 and a support plate 103 is provided below the positioning groove 102. The upper end surface of the support plate 103 is a concave arc surface. The blower body 200 includes a blower housing 201. The rear end of the blower housing 201 is provided with an installation pipe 203. A fixing member 204 is snapped onto the installation pipe 203. The fixing member 204 is installed on the base 101 by bolts. The drying mechanism 300 includes a drying pipe 301 installed at the air inlet of the blower body 200. An installation plate 302 is provided on the outer side of the front end of the drying pipe 301. The installation plate 302 is connected to the blower housing 201 by bolts. This invention allows the air entering the drying tube 301 to have sufficient time and space to fully contact the desiccant during its flow. The dried air prevents the polyacrylamide powder from getting damp, thus maintaining the good physical properties of the powder and preventing sticking due to moisture, thereby effectively improving the conveying efficiency of polyacrylamide.

[0022] Specifically, the front end of the fan housing 201 has a protruding annular edge that is embedded in the positioning groove 102. The outer surface of the fan housing 201 is located within the recessed arc surface at the upper end of the support plate 103. This structural design allows the fan to be placed more stably on the base 101 during operation, reducing vibration and displacement caused by fan operation, thus extending the fan's service life and ensuring its stability during operation, reducing the risk of component damage due to shaking.

[0023] Furthermore, an air outlet pipe 202 is provided on the side end of the fan casing 201, an impeller is rotatably mounted inside the fan casing 201, and a drive box 205 is installed at the end of the mounting pipe 203. The shaft of the impeller extends from the mounting pipe 203 to the drive box 205, where a driven pulley is installed. The drive box 205 can protect the pulley and the drive belt.

[0024] It is worth noting that a motor 206 is bolted to one side of the upper surface of the base 101. The output shaft of the motor 206 extends into the drive housing 205, where a drive pulley is installed. A transmission belt is provided between the drive pulley and the driven pulley. When the motor 206 operates, it can rotate the drive pulley, which in turn can rotate the driven pulley under the action of the transmission belt, thereby causing the impeller of the fan to rotate at high speed to blow air.

[0025] It is worth noting that the drying tube 301 gradually increases in size from front to back in a stepped manner. A drying chamber 308 is provided inside the drying tube 301, and a desiccant is placed inside the drying chamber 308. The inner wall of the drying tube 301 is evenly provided with mesh holes that communicate with the drying chamber 308. This stepped-like design of the drying tube 301 allows the air entering the drying tube 301 sufficient time and space to fully contact the desiccant during its flow, resulting in better drying of humid air.

[0026] It is worth noting that a second air inlet 304 is provided at the front end of the drying tube 301, and a feed inlet 303 is provided outside the second air inlet 304 at the front end of the drying tube 301. A double tube body 305 is provided at the rear end of the drying tube 301, and an air inlet channel 307 is formed between the double tube bodies 305. A first air inlet 306, which is connected to the air inlet channel 307, is opened at the rear end of the double tube bodies 305. The first air inlet 306 is arc-shaped. The air inlet channel 307 formed between the double tube bodies 305 can guide air into the drying tube 301 in an orderly manner. Combined with the first air inlet 306, the air entering the drying tube 301 can be distributed at a wide angle, so that the desiccant can be fully contacted during the air circulation, and the humid air can be effectively dried.

[0027] Working Principle: This embodiment provides a polyacrylamide conveying blower. During use, the motor 206 operates, causing the active pulley to rotate and drive the driven pulley, thereby enabling the impeller to rotate at high speed to supply air. External air can enter through the air inlet channel 307, and the air can enter the drying pipe 301 through the first air inlet 306. The first air inlet 306 is wide-mouthed, allowing the incoming air to pass through the stepped inner wall of the drying pipe 301, which is from large to small, so that the air can fully contact the desiccant, thereby drying the air. The dried air can enter the blower housing 201 through the second air inlet 304, and then the air can be discharged from the air outlet 202 to supply air for conveying polyacrylamide materials. The dried air will not cause the polyacrylamide powder to become damp, which can improve the conveying efficiency of polyacrylamide.

[0028] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
