Description

Technical Field

[0001] This utility model relates to the field of concentration and evaporation technology, specifically a tubular evaporator and concentrator. Background Technology

[0002] In industrial production or other fields, evaporation and concentration of various raw materials is a common processing method. Of course, there are many ways to evaporate and concentrate materials, including direct heating and evaporation of materials, and indirect evaporation treatment of materials.

[0003] Indirect evaporation is safer for raw materials as there is less direct contact between them. However, it also has some drawbacks and problems. For example, during heating and evaporation, since there is no contact between the evaporating material and the heating material, although the cleanliness of the material is improved, the heat distribution in the evaporating material is uneven during evaporation and concentration, which can easily lead to over-evaporation.

[0004] Therefore, we propose a tubular evaporator to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tubular evaporator concentrator to solve the problems mentioned in the background art.

A rotating shaft is installed and fixed on the inner ring of the sealed bearings. A stirring blade is provided at the top of the outer ring of the rotating shaft, and a rotating plate is provided at the bottom of the outer ring of the rotating shaft.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution for a shell-and-tube evaporator concentrator:

[0020] Example:

[0021] A tubular evaporator includes a heat transfer tube 1 installed and fixed inside the evaporator. Sealed bearings 2 are installed and fixed at both the upper and lower ends of the heat transfer tube 1. A rotating shaft 3 is installed and fixed on the inner ring of the sealed bearing 2. A stirring blade 4 is provided at the top of the outer ring of the rotating shaft 3, and a rotating plate 5 is provided at the bottom of the outer ring of the rotating shaft 3.

[0022] The minimum number of heat transfer pipes 1 is two, and each pair of heat transfer pipes 1 is connected and fixed by a bend 7.

[0023] The heat transfer pipe 1 has a partition plate 6 installed inside its cavity.

[0024] The stirring blade 4 is located outside the heat transfer tube 1, and the rotating vane 5 is located inside the heat transfer tube 1.

[0025] One side of the rotating piece 5 is in contact with the surface of the partition plate 6.

[0026] In this embodiment, the entire piping system is installed inside the cavity of the concentration equipment. Then, the mixture to be concentrated is added to the concentration equipment. After that, high-temperature gas or liquid is introduced into the cavity of the heat transfer pipe 1 through the external pipeline. The mixture in the concentration equipment is heated, evaporated and concentrated through the heat transfer pipe 1. When the flowing high-temperature gas or liquid hits the rotating plate 5, the rotating plate 5 will drive the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it drives the external stirring blade 4 to rotate. When the stirring blade 4 rotates, the mixture in the concentrator is continuously stirred. During stirring, the heat absorbed by the mixture can be uniformly processed to avoid excessive evaporation due to local overheating, which could cause excessive damage to the required substances or loss due to evaporation.

[0027] Meanwhile, as the rotating plate 5 rotates, it can also scrape the inner wall of the heat transfer pipe 1 and the surface of the partition plate 6 to keep the internal channels clean.

[0028] In this technical solution, by using a special heat transfer pipe 1 in conjunction with a rotating shaft 3 and stirring blades 4, the evaporated concentrate can be stirred during indirect heating, maintaining uniform heat distribution and avoiding problems such as material loss and damage caused by overheating.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
