DETAILED DESCRIPTION

[0014] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0015] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0016] like Figure 1 As shown, a sealing structure for the filter cloth edge of an emulsion vacuum filter includes a vacuum filter 13, a decompression chamber 1 is provided at the bottom of the vacuum filter 13, a chain bed 3 is provided above the decompression chamber 1, a filter cloth 4 is laid on the upper surface of the chain bed 3, two sets of sealing components are symmetrically arranged on both sides above the chain bed 3, the sealing components include a sealing strip 7 and a sealing pressing plate 8 located above the sealing strip, and a sealing pressing portion 14 is provided on the lower middle side of the sealing strip 7 to press on the upper surface of the filter cloth. The filter cloth is laid on the chain bed, and the chain bed is driven by the motor chain to move and drive the filter cloth to be updated, and the emulsion fills the top of the filter cloth. The emulsion on the filter cloth is blocked by the sealing strip, so that the emulsion does not flow away from the edge, but flows down the decompression chamber of the vacuum filter after being continuously filtered by the filter cloth, thereby improving the emulsion filtration efficiency and the filtration effect.

[0017] In this embodiment, the vacuum filter 13 is provided with support plates 6 supporting the sealing assembly on both sides, and a fixing plate 9 is provided above the sealing assembly. The fixing plates are welded and fixed on both sides of the vacuum filter 13. The fixing plates 9 are provided with threaded holes, and the threaded holes are provided with clamping bolts 10 with the lower ends pressing against the sealing pressing plates, and the clamping bolts are threaded with locking nuts 11 clamped on the upper side of the fixing plates. The support plates and the sealing pressing plates are matched to clamp the sealing strips, and by adjusting the clamping bolts on the fixing plates, the sealing strips are tightly pressed against the filter cloth by the sealing pressing plates, so that the emulsion will not flow away from the edge, but will continue to flow back to the vacuum filter decompression chamber after being filtered by the filter cloth; when the filtering capacity of the filter cloth decreases, the amount of emulsion passing through the filter cloth decreases, the resistance of the emulsion passing through the filter cloth increases, and the emulsion level rises. At this time, the chain bed will drive the filter paper to move and update, thereby continuing to filter the emulsion.

[0018] In this embodiment, the sealing assembly extends out of the support plate toward the lower middle side and bends downward, the sealing strip and the sealing pressure plate are tightly attached together, a slot is provided on the upper part of the sealing strip, and the edge of the sealing pressure plate toward the middle side is inserted into the slot.

[0019] In this embodiment, the sealing and pressing portion of the sealing strip is triangular in shape, and the lower tip of the sealing and pressing portion is pressed against the upper surface of the filter cloth.

[0020] In this embodiment, two rows of rollers 2 for supporting the chain bed are symmetrically arranged in the decompression chamber, and the rollers on the same side correspond to the sealing pressing part in the upper and lower positions. The chain bed travels on the rollers and the track plate, and moves the filter cloth between the rollers and the sealing strip, completing the laying and replacement of the filter cloth from the paper input end to the paper output end.

[0021] In this embodiment, track plates 5 supporting both sides of the chain bed are fixedly connected to both sides of the decompression chamber.

[0022] The roller 2 is in the vacuum filter decompression chamber 1, and the filter cloth 4 is placed on the chain bed 3. The chain bed drives the filter cloth to move on the roller and the track plate 5 through the driving mechanism (including motor, sprocket, chain). The sealing plate 8 is installed on the sealing strip 7, and the clamping bolt 10 is installed on the clamping plate 9. The clamping plate is pressed on the support plate by adjusting the clamping bolt. The edge of the sealing strip is pressed on the filter cloth under the action of the sealing plate. When the sealing strip and the filter cloth are attached without a gap, tighten the locking nut 11 to prevent the emulsion 12 from flowing away from the edge of the filter cloth, thereby improving the emulsion filtration efficiency. When the filtering capacity of the filter cloth decreases, the amount of emulsion passing through the filter cloth decreases, the resistance of the emulsion passing through the filter cloth increases, and the emulsion level rises. At this time, the driving mechanism will drive the chain bed and the filter cloth to move and continuously filter the emulsion.
