Topic: Importance and maintenance of control gate lock of evaporation pool in Yantian.
I. Introduction
In the process of making salt from seawater, the salt field is one of the important production facilities, and the evaporation pool, as an important part of the salt field, is mainly used to concentrate and crystallize brine into salt crystals through the natural evaporation power of sunlight and wind. In this process, in order to ensure that the brine can flow in the established direction and maintain a suitable concentration, it needs to be adjusted by means of various valves. This paper discusses one of the important equipment-the control gate lock of Yantian evaporation pool.
Second, the working principle of evaporation pool and the function of gate lock
The evaporation pool of salt field mainly relies on direct sunlight and wind blowing to speed up the evaporation of water in brine, so that the salt in the solution gradually precipitates into coarse salt particles. Because the concentration of brine varies greatly between different regions, it is necessary to set a special gate for controlling the flow direction of brine and match it with a corresponding locking mechanism, so as to effectively maintain the balance between various units in the whole system and ensure that the final product quality meets the requirements.
1. The gate structure analysis:
(1) Opening and closing mode: manual or electric driving device is adopted;
(2) Sealing performance: In order to prevent leakage, a special rubber gasket is usually coated on the contact surface.
2. Realization of locking function:
When a certain part completes the drainage task, it is necessary to close the corresponding channel in time to avoid wasting resources;
In addition, it can also avoid the overflow problem caused by unexpected situations (such as heavy rainfall).
Three, common fault types and their treatment methods
1. Material aging and deformation: long-term exposure to harsh environment will easily lead to corrosion and rust of metal parts; Solutions include regular inspection and replacement of damaged parts and application of anti-corrosion coatings.
2. Bad seal and serious leakage: besides strengthening daily maintenance, we should also pay attention to improving manufacturing accuracy and reducing gap error; If necessary, we can consider introducing new material technology to improve and upgrade it.
3. Control failure can't be turned on and off normally: This may be an electrical failure caused by insufficient power supply, short circuit and other reasons. The troubleshooting and maintenance personnel need to have certain professional knowledge and skills to accurately judge and eliminate hidden dangers.
4. Accident risk caused by operation error: It is suggested to arrange special personnel to guide the training for novice operators until the correct steps are mastered; At the same time, it is also essential to improve the safety rules and regulations and strengthen the supervision and assessment mechanism.
IV. Conclusion
To sum up, for enterprises engaged in sea salt production, strengthening the management and maintenance of key components in the evaporation pool control system, such as gate locks, is not only conducive to improving overall efficiency and reducing costs, but also related to the safety of employees' lives and property, so it must be paid enough attention!
