SU17203A1 - A device for filtering rosin - Google Patents

Description

The present invention relates to filtering devices consisting of a vertical cylinder connected to a vacuum pump, in the upper part of which is a filter element from a layer located between two grids.

In order to automatically regulate the already filtered rosin from the device to be filtered and to let out the filter, the cylinder in the proposed device is equipped with a float that alternately connects it to the vacuum pump or air using a valve, and controls the inlet and outlet of the filtered rosin.

In the schematic drawing of FIG. 1 shows a vertical section of the device and FIG. 2nd horizontal section along bc in FIG. one.

The filtering device consists of a vertical cylinder A, closed by a cover E with a hermetic closure. A pipe -F is welded into the cover E, through which rosin is injected and: from the containing rosin, ol and not shown in the drawing of the apparatus into the filter. Pipe F at the time of the inlet of the canister is connected to the drain valve of the apparatus. Inside the tube there is a valve that prevents air from entering the cylinder into the apparatus. Under cover E, a cotton filter a is placed, consisting of two grids and a layer between them. Inside cylinder A, in the longitudinal direction, it moves on wheels d along rails with a hollow float c. A sliding valve t is attached to the wheels and is designed to regulate the inlet and suction of air from the cylinder.

In the walls of the cylinder there are two holes 25 cm apart from each other. The top opening / is connected to a vacuum pump, and the bottom e serves to intake air. During the inactivity of the filter, the float with stands on the cross / inside the cylinder and the valve t closes the air inlet e, the cylinder is also connected to a vacuum pump, with which the same discharge is established inside it as in the apparatus. When there is a vacuum inside the cylinder, the rosin begins to flow from the apparatus, is filtered and drains to the bottom of the cylinder along the surface of the conical zoite & it serves to protect the float from being sprayed with rosin. Comes to the cross /, rosin and Ichinaet raise the float with, together with the valve t. In this case.

when the valve closes opening g and, consequently, turns off the vacuum pump and rises a little higher, the air inlet e opens, which closes the valve when the cylinder is filled with rosin and allows the filtered rosin to flow through valve K. into the substituted vessel.

With a decrease in the level of rosin in cylinder A, the float C is lowered together with the valve t, which again closes the air inlet e and connects the cylinder to the vacuum pump, whereby the rosin will again start to flow from the apparatus into the cylinder, etc.

The subject of the patent.

A device for filtering rosin, consisting of a vertical cylinder connected to a vacuum pump, in the upper part of which is a filter element of a layer located between two grids, characterized by the use of a hollow float moving in the longitudinal direction inside cylinder A, connected to the valve T, for alternately closing the suction port i and the air inlet to cylinder A.
