Description

Technical Field

[0001] This utility model belongs to the technical field of marine aquaculture equipment, and more specifically, it is a rotating anti-vibration device for the filter screen of a marine aquaculture microfilter. Background Technology

[0002] Currently, with the continuous improvement of people's living standards, the demand for seafood is also increasing, and the marine aquaculture industry is developing rapidly. Consequently, the demand for aquaculture equipment is also rising. Marine aquaculture microfiltration machines are essential equipment in this industry. Their working principle mainly utilizes a rotating drum for filtration. The drum has a dense stainless steel screen on its exterior, driven by a motor via gears. When the wastewater to be treated enters the microfiltration drum axially and flows out radially through the screen, impurities in the water (fine suspended solids, fibers, pulp, etc.) are trapped on the inner surface of the filter screen on the drum. When the impurities trapped on the filter screen are carried to the upper part of the microfiltration machine by the rotating drum, they are backwashed by pressurized flushing water into the slag discharge tank and flow out. The entire process requires no manual intervention and can achieve fully automatic filtration.

[0003] However, existing microfiltration machines are prone to clogging during use. Once clogged, the drum can easily vibrate due to eccentric rotation, often causing damage to the drum and resulting in frequent maintenance work, which brings significant costs to marine aquaculture. There is an urgent need for a device with a vibration-damping structure to solve this technical problem. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a vibration damping device for the rotating filter screen of a seawater aquaculture microfilter. This device effectively solves the vibration problem during the rotation of the filter screen, reduces damage to the drum caused by vibration, significantly lowers maintenance costs, and improves the economic benefits of seawater aquaculture. The specific technical solution is as follows:

Connecting longitudinal beams are horizontally arranged at the four corners of the supporting structure. A quadrilateral bracket structure is symmetrically arranged at the other end of each connecting longitudinal beam. The supporting structure, bracket structure, and connecting longitudinal beams together constitute a parallelepiped frame supporting structure. The filter roller is disposed within the parallelepiped frame supporting structure.

[0007] The middle part of the supporting beam is fixedly connected to the lower end of the drive wheel column; the two sides of the drive wheel column on the supporting beam are symmetrically provided with roller support structures, the upper side of the roller support structure is provided with a pressure roller structure, and the upper end of the drive wheel column is fixedly provided with a drive structure.

The pressure roller 21 is engaged in the isosceles trapezoidal groove on the upper surface of the rotating track 54 in a rolling and rotating manner, together with the support roller 31, to prevent the filter roller 5 from axially shifting or vibrating.

[0030] The roller support structure 3 includes rollers 31, roller support plate 32, roller adjustment shaft 33, and roller adjustment bolt 34. One end of the roller support plate 32 is rotatably connected to the support beam 41 via the roller adjustment shaft 33; the other end of the roller support plate 32 is connected to the support beam 41 via the roller adjustment bolt 34; a pair of rollers 31 are arranged side by side on the upper part of the roller support plate 32, and the roller adjustment bolt 34 can adjust the two rollers 31 to simultaneously contact the rotating track 54, jointly supporting the filter drum 5.
