Abstract

PURPOSE:To exchange a filter paper quickly, and to recover cake and the filter paper separately, by making a roll for winding a filter paper extended from a paper scroll, freely detachable, and providing a scraper to the front of the winding roll. CONSTITUTION:A used filter paper 2 is taken out from each filter plate 1 when a filtration is finished, by rotating sprocket wheels 12 used for a winding roll 7 after mutually separating respective adjoining filter plates 1, 1 by releasing a filter plate locking device 6. Then, each filter paper 2 is moved on a paper tray 18, and cake is exfoliated by a scraper 20 when the tray 18 is turned over by a guide roll 19, and only the filter paper 2 is wound up by the roll 7, and a new filter paper 2 unwound from a filter paper scroll is extended. When the roll 7 becomes large enough with the paper 2, the roll 7 is taken out by removing the nuts 10 used for a collet and rotating the rotary tops of respective bearings 8 as well, then an empty roll 7 is attached.

Description

Detailed Description of the Invention In this type of filter, synthetic paper made of synthetic fibers, etc. is used as the filter paper, but in order to achieve even higher precision filtration, diatomaceous earth is added as a p-percentage agent to the filter paper. They are often pre-coated and used, and in order to reduce the installation area, door panels are usually stacked in 10 or more layers one above the other.

In this type of filter, the door plates are stacked one on top of the other, so when replacing the filter paper, in order to pull out multiple sheets of long filter paper coated with diatomaceous earth at once, conventionally, the door plates are stacked on top of each other on the extended surface of each furnace plate. A drawer shelf is provided in each case, and a spike bar that moves in the longitudinal direction of the filter paper along the shelf pierces the diatomaceous earth and the filter paper and moves them horizontally to pull out the filter paper from the door plate.

However, with this method, the filter paper that has been pulled out, solid matter such as cake and diatomaceous earth that adheres to it, may become lumps on the drawer shelf, solid matter may be scattered around the offshore filter, or the filter paper and solid matter may Separate collection is difficult even when it is desired to collect each substance separately.

The present invention was proposed in view of the above circumstances, and is a horizontal furnace plate type filter that smoothly pulls out used F paper from each door plate and separates and collects the F paper and solid matter such as cake. A plurality of filter paper scrolls are provided on the paper feed side of a door plate stack formed by stacking a plurality of door plates so as to be releasable, and the F paper expanded from the filter paper scrolls is drawn out from the door plate. In a horizontal door plate type filter, each of which is inserted between the door plates, the filter is pivoted by a removable bearing on the paper discharge side, and one end is connected to a drive means via a detachable joint, and the F paper between the door plates is wound. The present invention is characterized in that it comprises a plurality of paper winding rolls for removing the paper, and a plurality of scrapers disposed in front of each of the tear paper winding rolls for peeling off the cake on the corresponding paper.

An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a side view thereof, Fig. 2 is a partially thick plan view showing the section ■ in Fig. 1, and Fig. 3 is a section III-Ill in Fig. 2. FIG.

In the above figure, ■ indicates that a plurality of overlapping oven plates 52 are each expanded by a plurality of filter paper scrolls pivotally supported by an obliquely installed paper rack 3, and the upper and lower adjacent door plates 1. 1, a plurality of sheets of F paper are wound up on rolls 7, each of which will be described later; 4 is an inlet header for supplying the stock solution to each door plate 1; 15 is an outlet header for merging the filtrate from each door plate 1; Reference numeral 6 denotes a door plate pressurizing device for tightening a plurality of stacked door plates l so that they can be freely separated by jacks, and 7 is provided on the paper discharge side of each door plate l, and both ends are pivotally connected via bearings 8 that can be freely inserted and removed. A plurality of winding rolls, 9 a rubber collet that removably connects each winding roll 7 to the shaft of a roll sprocket 12 via a collet nut 10 and a collet holder 11, 13 a speed reducer, 14 a speed reducer 13 15 is a frame installed obliquely approximately parallel to the paper rack 3; 16 is a sprocket for each adjacent roll) l
2. An idler sprocket is pivotally mounted between 2 and 12 and applies appropriate tension to the chain 17 that is rotated around each roll sprocket 12. 18 is a horizontal paper tray that guides each F paper 2, and 19 is a paper tray. A guide roll 20 is attached to the frame 15 and is attached to the frame 15, and the cake on the F paper 2 that is passed around the guide roll 19 is peeled off. There are multiple scrapers to collect this.

In such a device, when performing filtration, each door plate 1 is pressed by a furnace plate pressurizing device 6 via a geared motor and a jack.
．． 1 and tighten the F paper 2 between them, and force the undiluted solution to each door plate 1 through the inlet header 4 and rubber hose.The undiluted solution is filtered through the F paper 2 or diatomaceous earth in each door plate 1. It becomes a liquid and is taken out from the outlet header 5.

To take out the used F paper 2 from each door plate 1, the door plate pressurizing device 6 is loosened by a geared motor, and each adjacent furnace plate 1. After mutually separating 1...
The sprocket for each roll (12) is rotated via the reducer 13° chain 17.

Then, each F paper 2 moves to the right on the paper tray 18,
When it is reversed by the guide roll 19, the cake is peeled off by the scraper 20, so only the F paper 2 is wound onto the winding roll 7, and a new F paper is spread on each door plate l.

In this way, the F paper between each door plate can be easily replaced at the same time, and once the winding girroller has become thick enough with the F paper, removing the collet nut (to) will replace each bearing. 8
By rotating the rotary piece, the take-up roll 7 is taken out, and the empty take-up roll 7 is again pivoted to the bearings 8, 8, which is then connected to the H-ru sprocket via the rubber collet 9). 12 respectively.

According to such a device, one take-up roll 71 guide roll 19. Each scraper 20 has an inclined frame 15
Since it is attached along the
However, since the used paper can be replaced smoothly and the take-up roll can be quickly replaced, and since the cake is separated from the p-paper, it can be recovered without polluting the working environment.

In this embodiment, each winding roll 7 is commonly driven by one reducer 13, but it is also possible to drive a small compact motor by directly connecting each winding roll 7 separately.

In short, according to the present invention, a plurality of P paper scrolls are provided on the paper feed side of a door plate stack formed by stacking a plurality of door plates so that they can be separated, and the P paper expanded from the tear paper scroll is inserted between the oven plates. In the horizontal ν-plate type filter, a plurality of horizontal ν-plate filters are supported on the paper discharge side by removable bearings, one end of which is connected to a driving means via a detachable joint, each winding the ν paper between the F plates. By providing a paper winding roll and a plurality of scrapers placed in front of each of the paper winding rolls for peeling off the cake on the corresponding P paper, the paper can be exchanged quickly and the work environment is clean.

The present invention is extremely useful industrially because it provides a high-performance horizontal oven plate type filtration-like screened paper drawing device that enables individual collection of cake and lachrymal paper.
