6, filter cloth processing and installation method

This section is based on plate thickness 60mm, thickness 30mm filter cake as an example. Due to the different models, as well as a variety of working conditions under the filtration process is different from the production of cloth different ways, the user can consult to my company's technology department.

(1) cloth cover processing methods

1, the primary reference template diagram (a) shows, using plywood or other material produced a template, using metal plates around the hole wrap to prevent the electrical ferrochrome work Tanghuai template.

2, will be cut to 1080 × 1100mm as a filter cloth filter cloth films, cloth cut to 410 × 70mm as a set of intermediate connecting ring.

3, will reveal the width of 10mm triangular cloth piece around and used industrial sewing machine stitches (double side cloth reinforcement, pay attention to rectangular filter cloth, sewing cloth, after a good film can be found in Figure (b), dimensions in brackets as a reference size).

4, in the cloth-chip hot-hole φ5 three weeks or so (electric iron according to the size of the head diameter), hot in the single-layer filter cloth, the location can refer to diagram (b).

5, the template on the filter cloth on-chip, power chrome iron hot holes and washed out the middle hole. Washing hole hole hole location and the number of actual plate sizing.

6, take two tablets and an intermediate connection filter cloth cloth cloth cloth first intermediate connection piece sewing circle around the center hole diameter of approximately φ130 or so, and then gradually to sew 3-4 hole circle, until the inner ring diameter of φ105; and then re-join the middle of lap two stitches Junction; the end, the same method to connect the middle of a circle with another cloth pieces stitched together. (See Figure (c)

7, A-hole that motivated material I, B Kong, said in the Inlet. Under normal circumstances, the two only one, the two feeding methods filter cloth, its processing and installation the same way.

(2) Cloth film processing methods

1, will be cut to 1060 × 2190mm as a filter cloth filter cloth on their processing methods see Figure (d) and (1), supra.

2, A, B indicates that the feed hole, C, D, said feed hole upward mobility. Can only be opened at the same time A, B or C, D Hole.

3, electricity ferrochrome iron out the feed hole and washed hole, washing hole hole hole location and the number of actual plate sizing.

(3) installation method

1, the installation cloth cover, it will be one of the side of cloth rolled into cylindrical shape, and then through the plate center hole, and then start pave the way, with a plate on the truss with a belt filter cloth (see Figure e : filter cloth cover installation diagram).

2, installation of filter cloth films, usually use cloth folder (as shown in Figure g folders made of polypropylene filter cloth, filter cloth made of stainless steel clip, its slightly different shape with the figure g, this manual does not indicate otherwise) a fixed , the installation method see Figure f and Figure g.

(4) The filter cloth production and installation of Attention

1, electric ferrochrome can be used 500W.

2, be careful when ironing cloth, filter cloth filter part of the not burning, or else there are holes cloth, slurry through the filter cloth is easy, resulting in a fluid pressure difference on both sides of muddy and not the same, and in severe damage to filter board.

3, filter cloth to sew well, otherwise used for a period of time, the stitching easy to crack, resulting in a turbid liquid.

4, sewing machine pins should choose a reasonable, otherwise easily leak from the pin at material.

5, cloth worn on-chip to be away from the rope handle hole and tap position, and ensure the smooth cloth bag at the plate to the outside.

6, the user hole in the cloth, should fully understand the physical properties of the filter cloth. For easy to shrink cloth and must be shrunk, a fluid port (lotion mouth) hole size of plate holes about 70%. When installing filter cloth, filter cloth should pay attention to holes to be aligned with the plate hole, without folding, so as to avoid leakage. Filter cloth around the top and the plate ends is greater than 30mm is better. Cloth to use for some time to harden, its filtration performance degradation, this cloth should be regularly checked and any hardening phenomenon, then with the corresponding to the low concentration of weak acid or weak base, and (soaked 24 hours), to restore its.
