Description

A buffer structure for environmentally friendly vacuum unit

Technical Field

The utility model relates to the technical field of vacuum technology, in particular to an environmentally friendly vacuum unit buffer structure.

Background Art

In the chemical, pharmaceutical, textile, food, brewing, metallurgy, environmental protection and other industries, there are many vacuum processes, such as vacuum absorption, vacuum filtration, vacuum concentration, vacuum drying, vacuum transportation, vacuum deoxidation and vacuum oxygenation. These vacuum processes generally use water jet vacuum pumps as vacuum generating elements, and are combined with power sources, circulating water tanks, vacuum measurement and vacuum control components to form a new type of vacuum device.

In the prior art, the authorized patent with announcement number CN214146831U discloses an environmentally friendly vacuum unit buffer structure, including a positioning frame and two symmetrically arranged arc-shaped clamping plates, a threaded sleeve is rotatably connected to the center of the top of the positioning frame through a first bearing, and a matching threaded rod is inserted into the inner thread of the threaded sleeve, the top of the threaded rod is fixedly connected to a frame, the bottom of the frame is symmetrically fixedly connected to a sliding rod, and the sliding rod is slidably connected to the top of the positioning frame, and the opposite sides of the two arc-shaped clamping plates are fixedly connected to an L-shaped rod, and the vertical part of the L-shaped rod is fixedly inlaid with two guide sleeves matching the frame, and the L-shaped rod is slidably sleeved with the frame through the guide sleeve, and the horizontal part of the frame near both ends is movably sleeved with matching retaining rings. The utility model is not only convenient for positioning and clamping various pipelines of the vacuum unit, but also convenient for buffering and protecting them, and convenient for adjustment according to actual needs, effectively avoiding damage to the pipeline due to vibration.

However, the above technical solution still has the following shortcomings when in use: the above device uses the elastic force of the spring acting on the L-shaped rod to clamp the pipe with the arc-shaped clamp. When the pipe vibrates, the spring will reciprocate and contract, causing the arc-shaped clamp to be loosely clamped, resulting in unstable installation of the pipe. In this regard, we propose an environmentally friendly vacuum unit buffer structure to solve the above-mentioned problems.
