Abstract

The utility model relates to a diaphragm type filter press. In the solid-liquid separation of the coal slurry and the water, the common van-type filter press is now widely used to enable the separation of the coal slurry and the water; the equipment is replaced by the advanced diaphragm type filter press, but the replacement of the common van-type filter press by the diaphragm type filter press exists the problems that the investment is big, the van-type filter press replaced only is able to be discarded and other problems. The utility model is characterized in that: a plurality of diaphragm filter plates filtering through both sides and arranged a plurality of blowholes on the lateral face replace the filter plates on the used common van-type filter press with interval; a compressed air main pipe provided with the same quantity of branch pipes is arranged along the lateral face of the blowholes; a plurality of high-pressure hoses are used one by one to connect the blowholes on the diaphragm filter plates and the branch pipes on the compressed air main pipe. The utility model uses the more economical and practical method to graft the advanced diaphragm pressure filtration technique in the common van-type filter press, so as to enable the renewal of the common van-type filter press.

Description

The membrane pressure filter that common chamber-type press filter repacks into

Technical field

The utility model technology relates to the improvement technology of chamber-type press filter in a kind of black water Separation of Solid and Liquid field operation.

Background technology

In coal production, the process, generally use common chamber-type press filter in the black water Separation of Solid and Liquid engineering at present, yet a new generation is the chamber-type press filter of band membrane filter plate, i.e. membrane pressure filter, and have membrane pressure filter to substitute the trend of common chamber-type press filter greatly.Its reason be membrane pressure filter than the common chamber-type press filter that is using, better solid-liquid separation effect is arranged, bigger disposal ability and better economy are arranged.But if upgrade the common chamber-type press filter that generally uses in the existing Separation of Solid and Liquid engineering with membrane pressure filter, it is big investment just to have occurred, and the common chamber-type press filter of replacing can only be scrapped, and has caused certain problems such as the wasting of resources.

Summary of the invention

Purpose of the present invention just is to provide a kind of technology that economically common chamber-type press filter is transformed into membrane pressure filter.

Technical scheme of the present invention: the filter plate 1 that the side is had a two-face filtering band barrier film of air-filled pore substitutes the filter plate 2 on the common chamber-type press filter at interval, be furnished with the pneumatic manifold 4 that equates arm with membrane filter plate quantity along air-filled pore 3 one sides by adorning one, air-filled pore on the membrane filter plate and the arm on the pneumatic manifold linked with 5 ground of high-pressure hose.

Characteristics of the present invention: the filter plate that adopts the side to have the two-face filtering band barrier film of air-filled pore substitutes the filter plate on the common chamber-type press filter at interval, add simple air duct and just can repack membrane pressure filter into, its investment is less than changing 50% of a new membrane pressure filter, and the filter plate of replacing still can be used as spare parts, transform simple and the duration weak point, if even transform arrangement of time and must get well, can not influence use.

Description of drawings

Fig. 1 is common chamber-type press filter structural representation.

Fig. 2 is the structural representation that the utility model technology repacks common chamber-type press filter into membrane pressure filter.

The specific embodiment

Implement the detailed description of present technique

1, according to appearance and size that intend to transform common chamber-type press filter (Fig. 1) filter plate 2 and plup inlet, filtrate hole, handle, filter cloth, select corresponding side to have the filter plate 1 of the two-face filtering band barrier film of air-filled pore 3, and load onto filter cloth, standby.

2, prepare the pneumatic manifold 4 that length intends transforming the press filtration captain approximately, and press arm in the distance of two filter plate thickness of Guan Shangyi.

3, the interval hangs out the filter plate 2 on the common chamber-type press filter of figure (1), lifts up into above-mentioned standby filter plate 1.

4, state pneumatic manifold in the side that air-filled pore 3 is arranged by loading onto.

5, with 5 ground of high-pressure hose air-filled pore on the membrane filter plate and the arm on the pneumatic manifold are linked.

Claims

1, the membrane pressure filter that repacks into of common chamber-type press filter, it is characterized in that: the filter plate (1) that the side is had a two-face filtering band barrier film of air-filled pore substitutes at interval the filter plate (2) on the common chamber-type press filter, being furnished with the pneumatic manifold (4) that equates arm with membrane filter plate quantity by adorning one, air-filled pore on the membrane filter plate and the arm on the pneumatic manifold are linked with (5) ground of high-pressure hose along air-filled pore (3) one sides.
