Baffle plate in stirring tank

Abstract

The invention discloses a baffle plate in a stirring tank. The baffle plates are uniformly distributed between two and four places and arranged on the inner wall of the stirring tank and are parallel to a rotating shaft of stirring blades in the stirring tank, and the width of each baffle plate is 1 / 12-1 / 10 of the inner diameter of the stirring tank. Each baffle plate disclosed by the invention is a baffle plate group formed by arranging a plurality of small baffle plates at intervals, the height of each small baffle plate is 1 / 2-2 / 3 of the width of the small baffle plate, and a gap between every two adjacent small baffle plates is 1-2 times the height of each small baffle plate. The baffle plate is characterized in that a standard baffle plate is slit into a plurality of sections and the gaps are preserved by picking one part at intervals. Compared with the baffle plate with a slit, the baffle plate is equivalent to the baffle plate with the slit on the aspects of improving the mixing effect and efficiency, but has the advantage of reducing the energy consumption greatly, and has better energy-saving and consumption-reducing effects.

Description

technical field [0001] The invention relates to a mechanical stirring tank with baffles commonly used in the production process of chemical products. Background technique [0002] Mechanical stirring is an operation step often used in the production process of many chemical products. The stirred reactor is the most commonly used equipment to realize this mechanical stirring. Its traditional structure includes a stirring tank containing fluid materials (mixed liquid or mixed slurry), vertically arranged The rotating shaft in the middle of the stirring tank and the paddles fixed on the rotating shaft (the rotating shaft and the paddles, collectively referred to as stirring paddles). In order to eliminate the "vortex" generated by the liquid surface of the fluid material in the traditional mixing tank as much as possible, to avoid the accident of the fluid material overflowing the mixing tank, and to overcome the overall movement of the fluid material caused by the "vortex", wh...

Problems solved by technology

However, because the baffles in the "Stirred Reactor with Slotted Baffles" have something in common with other prior art, that is, each baffle is a single piece, from the upper end of the baffle to the lower end of the baffle. In the entire length range between them, the circular motion of the fluid material is blocked, so the energy consumption increased due to the addition of the baffle (called "baffle energy consumption" in this case) is also greatly reduced. limited
