Dissolving device having graded filtering and impurity removing mechanism and used for rosin resin production

Abstract

The invention discloses a dissolving device having a graded filtering and impurity removing mechanism and used for rosin resin production. The dissolving device comprises a dissolving barrel and a filtering barrel, wherein one end of the dissolving barrel is inserted into the filtering barrel, the dissolving barrel and the filtering barrel are fixed through a first bolt, a feeding port is formed in the upper end of the dissolving barrel, a driving motor is fixed to one side of the feeding port, a rotating shaft is arranged in the dissolving barrel, one end of the rotating shaft is rotatably connected with the inner wall of the dissolving barrel through a bearing, and one end of the rotating shaft penetrates through one side of the dissolving barrel to be fixed to one end of the output shaft of the driving motor. According to the invention, the filtering barrel is fixed below the dissolving barrel through the first bolt, and the first filter screen, the second filter screen and the third filter screen are sequentially arranged in the filtering barrel, so that a mixed solution in the dissolving barrel can be conveniently subjected to graded filtration, and the filtering effect of themixed solution is improved to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of rosin resin production, and in particular relates to a dissolving device for rosin resin production with a staged filtration impurity removal mechanism. Background technique [0002] Rosin is a light yellow to reddish-brown, thermoplastic mixture of various components. Its components are slightly different due to different types of resin. When producing rosin resin, it is necessary to dissolve the rosin, which is generally carried out in a dissolution tank. The process is not to dissolve conventional pine resin into water, but to heat the pine resin into a molten fluid through high temperature, and mix it with high-temperature water condensed by steam to form a fluid mixture, which contains solid impurities, and the mixture needs to be filtered , and then test the viscosity of rosin. [0003] However, in the prior art, most of the mixture dissolving devices do not have the function of graded filtration, ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of dissolving device for rosin resin production with graded filtration impurity removal mechanism, to solve the above-mentioned background technology, because most of the mixture dissolving devices in the prior art do not have the graded filtration function, so that the solution in the filtered solution It also contains fine particles, and the filtering effect is not ideal. When stirring the rosin in the dissolution tank, it is easy to shake, so that the detected viscosity value is not an accurate value.
