Description

FIG. one

The invention relates to press filters used in the chemical, food and related industries,

The purpose of the invention is to increase the operating efficiency and simplify operation.

Figure 1 shows a chamber filter press, a general view; 2 shows the pressure plate, front view; on fig.Z - compressed plate pack, a general view.

The chamber filter press contains filter plates 1 suspended from a pressure plate consisting of two parts — the top 2 and bottom 3, the clamping mechanism in the form of guides 4 in which the bellows 5 is located, with stroke limiter 6, the base plate 7 , on which the straps 8 are fixed, connected in the upper part by cross-pieces 9, spacers 10 are installed on the struts using levers.

The two parts (2 and 3) of the pressure plate are mounted so that they can move relative to one another in the vertical direction. The bellows 5 is fixed on the entire surface of the upper part of the pressure plate and connected to its lower part.

Chamber filter press works as follows.

The lifting mechanism lowers the pressure plate with filter plates 1 suspended on it to the base plate 7. At the same time, the gaps between the plates disappear, they lie on top of each other. After that, the spacers 10 are mounted by another mechanism between the cross-arms 9 and the upper part of the pressure plate 2. Next, the working fluid (oil) is injected into the bellows 5 under pressure, as a result of which the distance between the upper part of the pressure plate 2 and the lower 3 increases, sealing the filter bag plates 1. After the filtration process has been completed, the pressure in the bellows 5 is relieved, the struts 10 are advanced, the lifting plate rises with a lifting mechanism with filter plates 1 suspended on it,

Placing the bellows over the entire surface of the pressure plate ensures an even distribution of the load on the filter plates and, consequently, increases the reliability of the filter press operation.

It simplifies the operation of the filter press, since it does not require the installation of locking mechanisms, and there is also no need to periodically install and remove bellows.

Claims (1)
