Description

A kind of rotary sedimentation tank for composite stabilizer production

technical field

The utility model relates to the technical field of composite stabilizer production equipment, in particular to a rotary sedimentation tank for composite stabilizer production.

Background technique

Due to the poor stability of PVC products to light and heat, it will decompose to produce hydrogen chloride at temperatures above 100°C or exposed to sunlight for a long time, which is harmful to human health, and further autocatalytic decomposition, causing discoloration and rapid decline in physical and mechanical properties. During the processing of PVC products, compound stabilizers will be added to improve the properties of PVC products. The performance of PVC products used by people is improved and the use is safer.

Since part of the composite stabilizer is in liquid state, a settling tank is needed to separate and purify the impurities of the composite stabilizer during production and processing. When the traditional settling tank is used to prevent overflow, only an overflow pipe is provided to allow the liquid to flow out. The settled liquid is mixed with solid impurities, which is easy to cause blockage of the overflow pipe, resulting in that the liquid in the settling tank cannot be removed, the overflow pipe is difficult to clean, and sludge is easily accumulated at the bottom of the settling tank and the sewage pipe, causing the settling tank to settle and separate. The effect is weakened and the sewage pipe is blocked. For this reason, we propose a rotary sedimentation tank for the production of composite stabilizers.

Preferably, the heights of the overflow pipe, the feed pipe and the liquid outlet pipe are successively reduced, and the positions of the three pipes are set reasonably, so that the functions of the three pipes can be better realized, and the overflow pipe prevents the inner cavity of the settling tank shell from being trapped. Liquid level is too high.

Preferably, the height of the filter screen is located between the overflow pipe and the feed pipe to prevent the material from falling to the top of the filter screen through the feed pipe. When flowing out, the filter can play a filtering role, so that the overflow is clear liquid.

Preferably, the feed pipe, the liquid outlet pipe and the sewage pipe are all provided with solenoid valves, so as to facilitate the control of the material entering and leaving the inner cavity of the settling tank shell.

Preferably, the bottom of the inner cavity of the settling tank shell is in a funnel shape, which is convenient for sludge discharge, and the bottom of the shell scraper is matched with the bottom of the inner cavity of the settling tank shell, so that the shell scraper can pierce the inner cavity of the settling tank shell by the shell scraper. The sludge on the bottom of the cavity is cleaned.

Preferably, the two sets of left-right symmetrical scrapers of the sewage pipe have a maximum distance equal to the inner diameter of the sewage pipe, which is convenient for scraping off the sludge on the inner wall of the sewage pipe.

Compared with the prior art, the utility model has the following beneficial effects:

1. The utility model is provided with a filter screen, when the liquid level in the inner cavity of the settling tank shell continues to rise, and the overflow pipe needs to discharge excess liquid, the liquid is filtered through the filter screen, which can effectively reduce the entry of solid impurities into the overflow. flow pipe, reducing the risk of overflow pipe clogging;

2. The utility model reduces the height of the motor lifting column when the bottom of the sedimentation tank and the sewage pipe are cleaned and discharged. Through the rotation of the scraper on the bottom of the stirring rod and the bottom of the rotating shaft, the sludge falls off and can be smoothly Through the sewage pipe, the inner cavity of the sedimentation tank can be cleaned, the sludge concentration can be reduced, the sedimentation effect can be improved, and the risk of blockage of the sewage pipe can be reduced;

3. In the present invention, when the clear liquid is discharged through the liquid outlet pipe, the filter screen lifting column is extended downward, so that the height of the filter screen is lower than the height of the liquid discharge pipe. When the electromagnetic valve is opened to discharge the clear liquid, the clear liquid can be reduced. The solid impurities mixed in the filter can improve the quality of the clear liquid, and the filter screen has a small amount of solid impurities, which can reduce the number of filter cleaning and replacement, and reduce maintenance costs.
