Technical Field

The utility model relates to a pressure filter equipment field, especially a filter plate can be dismantled to plate filter press.

Background

The filtering equipment is mechanical equipment or a device for filtering, is common general equipment in industrial production and comprises vacuum and pressurization, wherein the vacuum type is commonly used by a rotary drum, a disc, a horizontal belt type and the like, and the pressurization type is commonly used by pressure filtering, squeezing, dynamic filtering, a rotating type and the like.

The plate type filter press has large filtering area and large flow, and is a filter press device which is often used in industry at present; the plate filter structurally comprises a frame, a pressing mechanism and a filtering mechanism:

1. the frame is a basic component of the filter press, the two ends of the frame are provided with a thrust plate and a compression head, the thrust plate and the compression head are connected by crossbeams at the two sides, and the crossbeams are used for supporting the filter plate, the filter frame and the compression plate;

2. a pressing mechanism: the filter comprises three types of manual compression, mechanical compression and hydraulic compression, and has the function of compressing a filter frame and a filter plate into a tightly combined row so as to form a filter chamber between the filter plate and the filter plate;

3. a filtering mechanism: consists of a filter plate, a filter frame, filter cloth and the like.

The basic principle of the plate filter is that filter plates, filter frames and filter cloth are arranged in a certain order and then are compacted into a tight row by a compacting mechanism, then feeding is carried out to the filter mechanism by feeding equipment through a feeding port, suspension liquid is fed into a filter pulp channel under specified pressure and flows into each filter frame through the channel; filtrate respectively passes through the filter cloth on two sides of the filter frame and is discharged from a filtrate outlet along a channel on the surface of the filter plate (the surface of the filter plate is uneven, so that the filtrate can flow conveniently); the particles are trapped by the filter cloth and deposited on the filter cloth, and the filtration is stopped after the filter cake fills the whole frame.

The filtering mechanism is the core part of the plate filter press for filtering and plays a key role.

The filtering mechanism of the plate filter used in the factory at present has simple structure, and only consists of a frame body with simple structure and block-shaped filter plates arranged at the front side and the rear side of the frame body, and the filter cloth plays a better filtering role in order to be opened and is directly fixed on the filter plates in a bolt way and the like; after the filter cloth is used for a long time, the filter cloth can be abraded to a certain extent and even can be damaged by sharp impurities contained in the suspension, and the filter cloth loses the filtering effect after being abraded and even damaged and needs to be replaced;

however, since the filter cloth and the filter plate are fixedly connected, replacement of the filter cloth and the filter plate means that the filter cloth and the filter plate need to be replaced together, and even if the filter cloth is connected with the filter plate in a detachable manner such as a bolt, the connection structure still needs to be opened first for replacement;

therefore, the filter cloth is inconvenient to replace due to the fixed connection of the filter cloth and the filter cloth, even the filter plate is damaged (such as scratching) carelessly in the replacement process, and the damaged filter plate can accelerate the damage of the filter cloth, so that great economic loss is brought.

The patent of publication number CN202120058685.0 discloses a filter-pressing plate for a plate filter press, which structurally comprises a plate frame, wherein an elastic bag is fixedly arranged in the middle of the plate frame, the elastic bag is communicated with a high-pressure pipe, two sides of the elastic bag are respectively provided with a squeezing plate, the squeezing plates are elastic plates, the edge positions of the squeezing plates are fixedly connected with the inner wall of the plate frame, two ends of the plate frame are respectively provided with filter cloth, the edge of the filter cloth is fixedly connected with the edge of the inner wall of the plate frame, the corner of the plate frame is provided with even-number water channels along the axis direction, the water channels penetrate through two ends of the plate frame, a communicating water channel communicated with a cavity between the squeezing plate and the filter cloth is arranged in the water channel, and the centers of the filter cloth, the squeezing plate and the elastic bag are provided with coaxial through holes. This for patent filter-pressing board is through redesign to the filter-pressing board, increase the application of force direction of extrusion force, promote the extrusion rate of inside moisture.

However, the patent adopts a mode that the filter cloth is fixedly connected with the edge of the inner wall of the plate frame, namely, the filter cloth of the patent is still fixedly connected, and the problems that the filter cloth is inconvenient to replace after being damaged, the filter plate is easy to damage due to replacement, and the filter plate is damaged to accelerate the damage of the filter cloth can also exist.

Therefore, the fixed connection of the filter cloth and the filter plate or the filter frame of the plate-type filter machine used at present has the problems that the filter cloth is inconvenient to replace after being damaged, the filter plate is easy to damage during replacement, and the filter cloth is damaged and is accelerated.
