Description

Technical Field

[0002] Chemical storage tanks are equipment used to store and transport various chemical substances. Chemical storage tanks can be divided into different types according to different material properties and tank structures. Chemical storage tanks need to be cleaned after each use. Some cleaning devices include tank bodies and cleaning pipes. The cleaning pipes are provided with adjustment mechanisms on the outside. The adjustment mechanisms include fixed grooves, baffles, slide grooves, fixed plates, long plates and connecting grooves. When the position of the baffles on the cleaning pipes is adjusted through the baffles, the long plates are pulled upward to release the clamping connection between the fixed plates and the connecting grooves. At this time, the fixed plates are pulled upward to release the clamping connection between the fixed plates and the fixed grooves. At this time, pull upward or push downward. The baffle makes the baffle be in a suitable position, and at this time, the fixed plate is pushed to be clamped in the inside of the fixed groove. At this time, the long plate is pressed downward to make the fixed plate clamped in the inside of the connecting groove. At this time, the baffle is fixed in the position of the cleaning pipe, which is convenient for adjusting the position of the baffle according to the depth of the chemical storage tank, so as to adapt to different chemical storage tanks. However, when the device cleans the chemical storage tank, the depth of the cleaning pipe is adjusted according to the depth of the chemical storage tank itself through manual control. This method requires manual operation by the staff and needs to be improved. In addition, the cleaning pipe can only be moved vertically, resulting in the cleaning coverage of the cleaning pipe in the chemical storage tank being always fixed, and there is room for improvement.
