The invention discloses a general tower teaching aid, relating to a teaching aid, in particular to a tower teaching aid which can be assembled into different structures. A base is connected with a tower section through a flange; a supporting ring is inserted into a connecting groove of the supporting ring annularly and uniformly distributed on the internal wall of the tower section through a connecting bulge of the supporting ring so as to be mounted on the internal wall of the tower section; a tenon on the supporting ring is inserted into a mortise of a connecting belt, and a connecting bulge of the connecting belt arranged on the connecting belt is inserted into a connecting groove of the connecting belt on the internal sidewall of the tower section for locating; a middle supporting beam and side supporting beams are arranged on the supporting ring; a middle liquid receiving dish is arranged on a lug type bracket in a middle position, and liquid receiving dishes on two sides are arranged on the side supporting beams and lug type brackets on two sides; the lug type brackets are arranged on the internal wall of the tower section through connecting bulges of the bracket on a rib plate of the bracket and connecting grooves of the lug type brackets on the internal wall of the tower section, and fixed by bolts; and an overflow weir and a down-flow plate are installed on the connecting belt from top to bottom through bolt holes on the connecting belt in combination with bolt holes on the down-flow plate and the overflow weir.
Description
technical field [0001] The general-purpose tower utensil teaching aid described in the present invention relates to a teaching aid, specifically a tower utensil teaching aid that can be assembled into different structures. Background technique [0002] At present, tower equipment is a mass transfer equipment commonly used in chemical production process, and it is also a compulsory course content for chemical engineering students in colleges and universities. [0003] Every tower equipment used in industry is a fixed welded structure with huge size and complex structure. With the help of theoretical descriptions in classrooms and textbooks, it is difficult to grasp the basic structure, and it is easier to form on the concept of fuzzy and abstract basic structure. The disadvantages of further study of relevant theoretical courses are often inefficient and unrealistic. [0004] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and...
