Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to an elevated tank. Background Art

[0002] The production process of pyrazolol includes dissolution process, reduction process, acidification process, cyclization process and oxidation process. In the dissolution process, water and ethylene glycol are added to the preparation kettle, stirring is started, and after stirring for 30 minutes, it is poured into the high-level tank, and then put into the dissolution kettle, and p-chloroaniline is added. The temperature is raised to 60 degrees to dissolve, and then stirred for 30 minutes, and then cooled to 0-5°C, sulfuric acid is slowly added dropwise, and after the addition is completed, it is stirred for 30 minutes, and the dissolved liquid is transferred to the transfer tank. The high-level tank is required in the dissolution process of pyrazolol production.

[0003] The high-level tank currently in use is a general storage container. After water and ethylene glycol enter the dissolving kettle from the high-level tank, para-chloroaniline needs to be added into the dissolving kettle and the temperature is increased. The existing heating is only carried out in the dissolving kettle, and the heating efficiency is low. If the water and ethylene glycol in the high-level tank can be heated in advance, the heating time of the materials in the dissolving kettle can be reduced, thereby improving the efficiency of the dissolving process.

[0004] In the prior art, the patent document with application number CN202222726662.X discloses a high-purity liquid alkali high-level tank, which can directly filter the liquid alkali to prevent impurities from accumulating on the inner wall of the high-level tank and being difficult to clean. By setting a filter screen placed inside the high-level tank, so that the bottom surface of the filter screen is directly in contact with the top of the liquid accumulation seat, the soda ash crystals can be accumulated on the bottom surface of the inner wall of the filter screen, thereby improving the purity when discharging the liquid alkali, and facilitating the subsequent cleaning of the high-level tank without scraping the wall, thereby improving the convenience of cleaning. By setting a connecting frame between the filter screen and the inner wall of the high-level tank, and a slider connected to one end of the connecting frame, the connecting frame can stably hang the filter screen on the inner wall of the high-level tank by relying on the bottom of the chute, and it is also convenient to pull the filter screen out from the inside of the high-level tank. The high device is suitable for small high-level tanks. When the volume of the high-level tank is large, the volume of the filter screen increases accordingly, and there are great safety hazards in the process of pulling out the large filter screen.

[0005] The patent document with application number CN202021926309.0 discloses a high-level tank, which can make the impurities in the liquid deposit to the side with a cleaning port by setting an inclined filtering device, which is easy to clean and effectively reduces the possibility of blocking the filtering device. The high-level tank of the utility model effectively avoids blocking the filtering device during use by setting a stirring fan blade above the filtering device, thereby improving the passage efficiency of the liquid. In general, the high-level tank of the utility model has a simple structure, is easy to clean, and ensures the passage efficiency of the liquid. The filtering device of the high-level tank can discharge the filtered impurities without being taken out. However, impurities attached to the filtering device are not convenient to remove, and when impurities accumulate on the filtering device for a long time, it is easy to cause blockage of the filtering device.
