Embodiment 1

[0037] Embodiment 1, the public works module, the reaction module, the crystallization module, and the sieve plate rectification module are connected sequentially to form a modular teaching practice device for an aspirin production line, such as Figure 14 shown.

[0038] The device can modularize and scale the aspirin production line and install it in the laboratory, which is convenient for practical teaching work, and can be freely assembled to exercise students' hands-on ability and creative ability, and the risk is greatly reduced.

[0039] In the reaction module, add acetic anhydride solution to the acetic anhydride raw material tank fy1, add salicylic acid to the reactor fy3, turn on the reactor fy3 and the acid anhydride pump fy2, add the acetic anhydride raw material tank to the reactor fy3 through the acid anhydride pump fy2, and then Add concentrated sulfuric acid to the reactor fy3 through the constant pressure funnel on the reactor fy3, turn on the heating circulat...

Embodiment 2

[0043] Embodiment 2: Connect the water distribution module, A2O module, and post-treatment module in sequence to form a teaching practice device for a sewage treatment production line, such as Figure 15 shown.

[0044] The practice method utilizing the teaching practice device of the sewage treatment production line comprises the following steps:

[0045] 1) Carry out practical operation of water distribution, including the following steps:

[0046] 1.1) According to practical requirements, manually set the upper limit and level difference of the circulating water tank 101 of the control system through the touch screen, and set the upper limit and temperature difference of the circulating water tank 101;

[0047] 1.2) Open the valve 118 to supply water to the circulating water tank 101. When the liquid level of the circulating water tank 101 rises to the actual required water level, open the valve 112, start the circulating water pump 106, and maintain the running state of t...

Embodiment 3

[0067] Embodiment 3: The public engineering module, the reaction module, the crystallization module, and the sieve plate rectification module are connected in sequence to form a modular teaching and practice device for a pharmaceutical intermediate production line.

[0068] For the specific operation process of the modular teaching practice device of the pharmaceutical intermediate production line, please refer to the Chinese invention patent with the application number: 201711173843.1 and the invention name: the teaching device for the benzamide production line. The teaching practice device has been publicly explained.

Abstract

The invention discloses a general modular teaching practice device for chemical production lines. The device comprises a public engineering module, a reaction module, a crystallization module, a sieveplate rectification module, an emulsification module, a slurry blending module, an evaporative condensation module, a pretreatment module, an extraction module and a drying module and also comprisesa water distribution module, an A2O module, an aftertreatment module and an electric control system. All the modules are freely matched, combined and connected according to teaching practice requirements, the electric control system comprises electric control cabinets arranged in all the modules, and the electric control cabinet in each module is provided with a controller and a touch screen. Thedevice can effectively help students master related knowledge of various chemical treatment processes and basic principles of the treatment processes, enhance the ability of students for controlling various chemical production treatment process indexes and improve capacity for chemical production line design, building, debugging and control operation.

Description

technical field [0001] The invention relates to the technical field of teaching practice in chemical production lines, in particular to a universal modularized teaching practice device for chemical production lines. Background technique [0002] At present, the regional distribution of the world's chemical industry is mainly in developed countries. my country's chemical industry accounts for a relatively small proportion of the world's chemical industry. severe scarcity. Our country urgently needs to train some talents in chemical production, and in most colleges and universities in our country, there is a lack of teaching practice devices for chemical production lines. The teaching equipment is single, and often one device can only be used for one chemical production line. Well, experimental capabilities are limited. Therefore, in view of the current situation of chemical production line teaching in my country, it is urgent to set up a general modular teaching practice dev...
