Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ultrasonic-assisted wastewater treatment descaling device. Background Technology
[0002] With the continuous advancement of industrialization, wastewater treatment has become a crucial link in ensuring environmental safety and resource recycling. As the core equipment of a wastewater purification system, the internal structure and operating status of the wastewater treatment tank directly affect treatment efficiency and equipment lifespan. During wastewater treatment, suspended particles, organic matter, and minerals in the wastewater easily deposit on the inner wall of the tank, forming scale. This leads to decreased heat exchange efficiency, increased fluid resistance, and even corrosion and blockage, severely impacting the stable operation and maintenance costs of the wastewater treatment system.
[0003] Traditional wastewater treatment tanks typically use mechanical scraping to clean the inner walls, employing scrapers or blades to physically scrub the tank walls and prevent scale buildup. While this type of mechanical scraping can mitigate scaling to some extent, it has significant drawbacks. First, the mechanical scraping structure is generally fixed or partially rotating, with limited coverage, making it difficult to achieve comprehensive cleaning of the tank's inner walls and creating blind spots and dead zones where scale remains. Second, friction during mechanical scraping causes wear and tear; prolonged contact between the scraper and the tank wall accelerates equipment wear, increasing maintenance frequency and costs. Third, mechanical scraping alone is limited in its effectiveness against stubborn scale, failing to completely remove firmly adhered layers and impacting treatment efficiency. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides an ultrasonic-assisted wastewater treatment descaling device to solve the aforementioned problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic-assisted sewage treatment descaling device, comprising a fixed outer cylinder, a treatment cylinder rotatably connected inside the fixed outer cylinder, ultrasonic generators installed on the cylinder walls at the four positions of front, back, left, and right on the outside of the fixed outer cylinder, a rotary drive component installed on the cylinder wall of the fixed outer cylinder to drive the treatment cylinder to rotate inside the fixed outer cylinder, a top cover installed at the top of the fixed outer cylinder, a U-shaped scraper installed at the bottom inside the top cover, and the outer side wall of the U-shaped scraper tightly fitting against the inner side wall and bottom of the treatment cylinder.
[0008] As a preferred technical solution of this utility model, the rotary drive component includes a geared motor, a drive gear, and a transmission gear ring. The geared motor is installed on the right side wall of the outer wall of the fixed outer cylinder, the drive gear is installed on the output end of the geared motor, and the transmission gear ring is fixedly sleeved on the outer wall of the processing cylinder. The drive gear and the transmission gear ring mesh with each other.
[0009] As a preferred technical solution of this utility model, a transmission window is provided on the right side wall of the fixed outer cylinder for the drive gear and the transmission gear ring to mesh.
[0010] As a preferred technical solution of this utility model, a bearing that cooperates with the rotation of the processing cylinder is installed on the inner wall of the fixed outer cylinder.
[0011] As a preferred technical solution of this utility model, a feed pipe is installed at the center of the top of the top cover.
[0012] As a preferred technical solution of this utility model, an outlet valve pipe is installed at the center of the bottom of the processing cylinder, and the outlet valve pipe passes through the center of the bottom of the fixed outer cylinder.
[0013] As a preferred technical solution of this utility model, the bottom of the fixed outer cylinder is equipped with four support legs that are supported on the ground.
[0014] Compared with the prior art, this utility model provides an ultrasonic-assisted wastewater treatment descaling device, which has the following beneficial effects:
[0015] This device utilizes a rotatable treatment cylinder 2 within a fixed outer cylinder 1, achieving 360° uniform rotation of the inner wall of the treatment cylinder 2. This allows the ultrasonic generators 6, evenly distributed on all four sides of the fixed outer cylinder 1, to deliver ultrasonic radiation to the wastewater within the treatment cylinder 2 without any blind spots. The cavitation effect and micro-vibrations generated by ultrasound in the water effectively disrupt the adhesion structure of dirt, promoting its removal and suspension, significantly improving descaling efficiency. The rotation of the treatment cylinder 2 avoids localized concentrations or blind spots in ultrasonic energy, ensuring that the entire inner wall receives sufficient ultrasonic waves, greatly reducing the descaling dead zones that are common in traditional ultrasonic descaling equipment.
[0016] In addition, the U-shaped scraper 7 installed inside the device is in close contact with the inner wall and bottom of the treatment cylinder 2. As the treatment cylinder 2 rotates, it scrapes synchronously, mechanically removing the attached dirt and preventing dirt deposition and accumulation. The synergistic effect of the mechanical scraper and ultrasonic waves not only enhances the thoroughness of dirt removal but also avoids the efficiency bottlenecks and equipment wear problems that may result from a single descaling method, thus extending the service life of the equipment.
[0017] By combining ultrasonic radiation (without blind spots) with mechanical scraping for descaling, the device effectively addresses scaling issues during wastewater treatment, ensuring the inner wall of the treatment tank remains clean over the long term. This reduces maintenance frequency and operating costs, while enhancing the stability and reliability of wastewater treatment. Furthermore, the design is compact and features smooth transmission, making it suitable for large-scale industrial applications and possessing broad prospects for widespread adoption and practical value.
[0018] In summary, this ultrasonic-assisted wastewater treatment descaling device innovatively combines a 360° rotating treatment cylinder with a multi-directional ultrasonic generator, achieving omnidirectional, blind-spot-free ultrasonic descaling and overcoming the technical bottlenecks of uneven energy distribution and descaling blind spots inherent in traditional equipment. Combined with a U-shaped mechanical scraper closely attached to the inner wall, a highly efficient synergistic mechanism of ultrasonic and mechanical scraping is formed, significantly improving the thoroughness of descaling and the stability of equipment operation during wastewater treatment. This device not only improves wastewater treatment efficiency and reduces equipment maintenance difficulty, but also possesses advantages such as reasonable structure, simple operation, and strong adaptability. It has significant engineering application value and promotion potential, providing a highly efficient and reliable new descaling solution for the wastewater treatment field.

[0031] Please see Figure 1-4 An ultrasonic-assisted wastewater treatment descaling device includes a fixed outer cylinder 1, with a treatment cylinder 2 rotatably engaged inside the fixed outer cylinder 1. The treatment cylinder 2 is rotatable around an axis inside the fixed outer cylinder 1, and a transmission gear ring 33 is fixedly sleeved on its outer wall. Ultrasonic generators 6 are installed on the four outer walls of the fixed outer cylinder 1 (front, back, left, right), respectively, for emitting ultrasonic waves to the wastewater inside the treatment cylinder 2, thus enabling 360° ultrasonic descaling of the interior of the treatment cylinder 2 in conjunction with the rotatable treatment cylinder 2.
[0032] A transmission window 12 is provided on the right side wall of the fixed outer cylinder 1. A drive mechanism is installed inside the transmission window 12, including a geared motor 31 mounted on the right side wall of the fixed outer cylinder 1. A drive gear 32 is installed at the output end of the geared motor 31, and the drive gear 32 meshes with a transmission gear ring 33 on the outer wall of the processing cylinder 2. The geared motor 31 drives the drive gear 32 to rotate, thereby driving the transmission gear ring 33 and the processing cylinder 2 connected to it to rotate. This design allows all directions of the inner wall of the processing cylinder 2 to make full contact with the ultrasonic waves emitted by the ultrasonic generators 6 on all four sides.
[0033] A bearing 4 is installed on the inner wall of the fixed outer cylinder 1. The bearing 4 works in conjunction with the rotation of the treatment cylinder 2 to ensure smooth rotation of the treatment cylinder 2 and reduce friction and wear. A top cover 5 is provided at the top of the fixed outer cylinder 1. A feed pipe 51 is installed at the center of the top of the top cover 5 for the entry of sewage. A U-shaped scraper 7 is installed at the bottom inside the top cover 5. The outer wall of the U-shaped scraper 7 is in close contact with the inner wall and bottom of the treatment cylinder 2. As the treatment cylinder 2 rotates, the scraper 7 scrapes the inner wall of the cylinder to prevent dirt deposition and promote the descaling effect.
[0034] A discharge valve pipe 21 is installed at the center of the bottom of the treatment cylinder 2. The discharge valve pipe 21 extends out of the center of the bottom of the fixed outer cylinder 1 and is used for the discharge of treated wastewater. Four support legs 11 are installed at the bottom of the fixed outer cylinder 1, which support the entire device and fix it stably to the ground.
[0035] Working Principle: Wastewater enters the treatment cylinder 2 through the feed pipe 51 at the center of the top cover 5. Supported by the bearing 4 inside the fixed outer cylinder 1, the treatment cylinder 2 is driven by the geared motor 31 to rotate the drive gear 32, which in turn transmits power to the transmission gear ring 33, enabling the treatment cylinder 2 to rotate 360°. During rotation, the inner wall of the cylinder receives ultrasonic waves emitted by the ultrasonic generators 6 on all four sides of the fixed outer cylinder 1, enhancing the descaling effect and preventing dead zones. Simultaneously, as the treatment cylinder 2 rotates, the U-shaped scraper 7, which is closely attached to its inner wall and bottom, scrapes the cylinder wall, further assisting in cleaning up dirt deposits and promoting dirt removal. After the action of ultrasonic waves and mechanical scraping, the dirt is effectively removed and suspended in the wastewater. The treated wastewater is discharged from the device through the outlet valve 21 at the center of the bottom of the treatment cylinder 2, completing the entire descaling process.
