Efficient and energy-saving rubber dispersing and dissolving apparatus

Abstract

The invention relates to the field of chemical mechanical equipment, and especially relates to an efficient and energy-saving rubber dispersing and dissolving apparatus. The apparatus comprises a supporting frame and a reaction kettle arranged on the supporting frame, a stirring device and a rubber block tearing device are arranged in the reaction kettle, the top and the bottom of the reaction kettle are communicated through a circulating pipeline, a circulating pump is arranged on the circulating pipeline, and a pressure weighing device is arranged between the upper portion of the reaction kettle and the supporting frame. Compared with like apparatuses in the prior art, the apparatus has the following advantages: the apparatus is high in automation degree, the rubber cutting procedure before dissolution is omitted, and rubber blocks can be directly put into a reaction kettle, so the danger of rubber cutting operation is avoided, and pollution is reduced; and through cooperative use ofthe stirring device, the rubber block tearing device, a base oil heater and the circulating pipeline, the rubber dissolving time is greatly shortened, rapid dispersion and dissolution of polymer rubber in base oil are achieved, and the apparatus can also be used for blending lubricating oil and paint which require dispersion and homogenization.

Description

technical field [0001] The invention relates to the field of chemical machinery equipment, in particular to a high-efficiency and energy-saving rubber dispersing and dissolving device. Background technique [0002] Lubricating oil tackifier, also known as viscosity index improver, is an oil-soluble polymer with a relative molecular mass ranging from tens of thousands to hundreds of thousands, and is generally in the form of rubber or solid at room temperature. For ease of use, it is usually diluted to a 5% to 12% concentrate with 150SN or 100SN neutral oil. In the traditional production of lubricating oil, the polymer rubber is dispersed and dissolved in the base oil. The base oil needs to be added to the blending kettle, and the blending kettle is heated to keep it at a certain temperature.

Problems solved by technology

In the traditional production of lubricating oil, the polymer rubber is dispersed and dissolved in the base oil. The base oil needs to be added to the blending kettle, and the blending kettle is heated to keep it at a certain temperature. The tackifier dry glue is chopped and manually poured into the blending kettle Add the cut dry glue, stir and mix evenly, it usually takes 10-30 hours, even if it takes such a long time, due to the mixing of lubricating oil and tackifier in the mixing tank, the polymer binder rubber is easy to float on the oil surface On, or adhered to the wall of the device, the top of the heating coil, resulting in uneven blended binder concentrate, unable to fully mix the dry glue containing macromolecular chains into the lubricating oil, the lubricating oil produced with this concentrate When in use, it is easy to delaminate, and due to frictional heating, the viscosity of the oil decreases, and the dry glue is easy to precipitate. The precipitation of the dry glue will further reduce the viscosity of the oil. Such a vicious cycle will seriously affect the lubricating performance of the oil, and even cause the lubricating oil complete failure of

At the same time, due to the low efficiency of simple constant temperature stirring, slow stirring speed, or insufficient heat preservation, the long sol time is not conducive to the production efficiency of lubricating oil

In addition, when cutting rubber blocks by hand or simple machinery, the safety of the operation is poor, the speed is low, and the pollution is serious
