Problems solved by technology
[0004] The disadvantages of the above-mentioned rotary stretching device are: 1. When the rotary stretching device is driven to rotate, the pitch of the sheet is affected by factors such as the rotating speed of the rotary stretching device, the number of revolutions, and the conveying speed of the sheet. (Equivalent to the turbulence unit referred to below) are not exactly the same. After such a spiral bond is installed in the tube bundle, the fluid in different positions in the tube bundle will receive different turbulence, resulting in uneven heat transfer; or the rotating stretching device is set Unreasonable, too many turns will cause the sheet to be twisted off

The invention belongs to the technical field of heat exchanging equipment and discloses a turbulent flow belt clamping and rotating mechanism. The mechanism comprises a prewire cutting part and a twisting part in sequence in the sheet conveying direction, wherein the prewire cutting part comprises two sets of cutters perpendicular to the sheet conveying direction, and a power mechanism controlling the cutters to move up and down, and each set of cutters comprises two cutters which do not make contact and are located on the same line; the twisting part comprises two parallel clamping blocks, and a gear mechanism which is connected with the clamping blocks and controls the clamping blocks to rotate, and grooves parallel to the sheet conveying direction are formed in opposite sides of the two clamping blocks. Turbulent flow units of a turbulent belt formed through twisting of the turbulent flow belt clamping and rotating mechanism have the same length and can be cut off easily.
Description
technical field [0001] The invention belongs to the technical field of heat exchanger equipment. Background technique [0002] Tube heat exchanger, which is the most typical partition heat exchanger, has a long history of industrial application, and still occupies a dominant position in all heat exchangers. The tubular heat exchanger is mainly composed of a shell, a tube bundle, a tube plate and a head. The shell is mostly circular, and there are parallel tube bundles inside, and the two ends of the tube bundle are fixed on the end plate. There are spiral ties (also known as twisted iron, spoiler belt, spiral flat steel, etc.) in the rotating connection in the tube bundle, and the spiral ties are mainly used to improve heat exchange efficiency. When the fluid enters the heat exchange tube, the spiral bond makes the fluid enter a turbulent state, breaks the stagnant layer of the tube wall, increases the contact area between the fluid and the tube wall of the heat exchange tu...
