Description

TECHNICAL FIELD

[0001] The utility model relates to chemical equipment cleaning technical field, specifically, relate to a pipe orifice of chemical equipment is blocked up tool. BACKGROUND

[0002] After the chemical equipment runs for a long time, the complex physical and chemical changes inside the equipment will inevitably produce some solid impurities. In the whole process of chemical production, various materials are always in a fluid state of continuous flow, and the newly generated solid impurities will mix with the flowing medium and move together. The fluid continues to flow forward, and when it flows near the pipe orifice of the equipment, the cross-sectional area of the pipe orifice is much smaller than that of the main part of the pipe. When the impurities flow in the relatively spacious pipe, the distribution is relatively dispersed, but when they enter the narrow area of the pipe orifice, their activity space is greatly compressed, and they cannot move smoothly and can only gather here. With the passage of time, the accumulated impurities become more and more, gradually occupying the space of the pipe orifice, and finally making the flow cross section of the pipe orifice narrower and narrower, and further causing the pipe orifice to be blocked. This will bring a lot of obstacles to the normal operation of the chemical equipment, such as unsmooth fluid delivery, abnormal rise or drop of pressure, etc.

[0003] In chemical production, pipe orifice blockage can cause many troubles, in order to avoid these adverse effects, the common methods at present are manual cleaning or using high-pressure water or gas flow to clean the blockage, but both methods have defects. As for manual cleaning, most of the chemical equipment is in a dangerous production environment, and the operator must directly face toxic and harmful gases, flammable and explosive substances, high temperature and high pressure, etc., and the personal safety is threatened at any time. Moreover, the efficiency of manual cleaning is very low, and the pipe orifice of large-scale chemical equipment is numerous and complex, which consumes a lot of time and labor to clean up, which is easy to prolong the downtime of the equipment and further affect the production progress, causing great economic loss. For high-pressure water or gas flow, although this method can be operated remotely and the operator does not need to directly contact dangerous substances, but if the deposited material is hard or solidified, the cleaning effect is not good, and high-pressure washing cannot achieve the expected cleaning effect. In addition, high-pressure washing may damage the pipe and equipment. UTILITARIAN CONTENT

On the one hand, such a design makes the overall structure more compact, and in the limited installation space of the blockage clearing tool, the components can be reasonably arranged to avoid installation difficulties caused by component size conflicts and ensure smooth assembly of the equipment. On the other hand, the smaller caliber of the lead screw 5 requires relatively less driving force when rotating to adjust the drive shaft 2 to advance and retreat, which is more labor-saving, reduces the labor intensity of the operator, improves the work efficiency, and also reduces the power requirement of the driving components, which is beneficial to prolong the service life of the equipment and ensure the stable development of the blockage clearing work.
