Automatic organic tin adding device and inspection and monitoring method

Abstract

The invention relates to the technical field of sectional material and pipe production, and particularly discloses an automatic organic tin adding device. The automatic organic tin adding device comprises an organic tin adding machine and a perpendicular adding pipe arranged at the output end of the organic tin adding machine. The perpendicular adding pipe comprises a front level pipe and a rear level pipe, wherein the front level pipe is connected with the rear level pipe through an angle seat valve, a through hole is formed in the valve body of the angle seat valve, and the valve body is connected with a pressure transmitter used for checking the amount of stored organic tin in the front level pipe. The automatic organic tin adding device further comprises a monitoring instrument connected with the pressure transmitter and used for converting electric signals output by the pressure transmitter into digital display values. With the automatic organic tin adding device, the amount of added organic tin can be directly observed, and the phenomenon that the quality of pipes or sectional materials is affected because organic tin is not added, or the amount of added organic tin is insufficient, or organic tin is repeatedly added is avoided.

Description

technical field [0001] The invention relates to the technical field of profile and pipe production, in particular to an organotin automatic adding device and a detection and monitoring method. Background technique [0002] As a heat stabilizer for PVC, organotin is widely used in the processing and production of PVC pipes, profiles and various products. Proper amount of organotin should be added in the production process of PVC resin and various formula mixes. The methods of adding are usually manual weighing and adding or automatic adding by machine. Equipment factors such as damage to the sealing ring of the feeder affect the amount of organotin fed, and it is impossible to see whether there is actually organotin in the closed pipeline, and the amount of organotin cannot be observed and grasped intuitively. Furthermore, since there is no visual data display and historical records to check and check, the above-mentioned human or equipment reasons will easily lead to the oc...

Problems solved by technology

Proper amount of organotin should be added in the production process of PVC resin and various formula mixes. The methods of adding are usually manual weighing and adding or automatic adding by machine. Equipment factors such as damage to the sealing ring of the feeder affect the amount of organotin added, and it is impossible to see whether there is actually organotin in the closed pipeline, and the amount of organotin cannot be observed and grasped intuitively

Furthermore, since there is no visual data display and historical records to check and check, the above-mentioned human or equipment reasons will easily lead to the occurrence of missed, under-added or repeated addition of organic tin, which will affect the quality of PVC pipes, profiles and other products. Quality takes its toll and waste

Without a stable and reliable organotin automatic adding device and detection and monitoring method, it is difficult to guarantee the stable performance of PVC formula, and it cannot meet the needs of efficient and intelligent automatic production of PVC products
