Description

Technical Field

[0001] The present invention belongs to the technical field of open-flow automatic filter press (patent classification number B01D25 / 12), and relates to an open-flow liquid receiving trough device which turns to avoid vibration plate unloading to prevent filter cake from collapsing. Background Art

[0002] A filter press is a pressurized filtration device with multiple filter chambers that operate intermittently. An open-flow automatic filter press is a filter press with multiple filter chambers that discharge liquid in an open flow manner, so that the clarity of the filtrate can be observed. It is mainly composed of a double-beam frame, a filter plate clamping mechanism, an open-flow filtration mechanism and its open-flow liquid receiving tank, a flip-plate liquid receiving mechanism, a pulling plate vibration cake unloading mechanism, a filter cloth cleaning mechanism, and a PLC program control system. The main working process of the filter press is: filter plate clamping, low-pressure feeding, open-flow filtration (including open-flow liquid receiving), pulling the filter plates, vibrating plate cake unloading, and filter cloth cleaning. It is suitable for solid-liquid separation of various viscous suspension materials (i.e., a mixture of liquid and solid particles).

[0003] The open flow filtration mechanism, that is, the open flow liquid type multi-filter chamber filtration mechanism, is the core mechanism of the open flow filter press. It is mainly composed of head and tail sealed anti-corrosion filter plates, open flow filter plates, filter cloths, cloth-clamped distributors, filter plate sliding supports, open flow nozzles, open flow liquid receiving troughs, sealing rings at the ends of each fluid inlet and outlet holes, and external inlet and outlet pipes for each fluid; double open flow nozzles are installed under both sides of the open flow filter plates respectively, and the filtrate of the multiple filter chambers flows directly from two rows of open flow nozzles and transparent guide pipes (not concealed) to the open flow liquid receiving trough, and then flows into the external filtrate pool through two open flow pipelines; the clarity and turbidity of the filtrate can be observed through the transparent guide pipe to diagnose whether the filter cloth is damaged or leaking.

[0004] The open flow receiving trough, that is, the fixed open flow receiving trough, includes the receiving trough body, the discharge pipe flange, the slot cross brace, and the splash plate. It is an important characteristic component of the open flow filtration mechanism. The double open flow receiving trough spans the head and tail of the filter press and is fixedly installed on the head support legs, the trough bracket, and the tail support legs. It is located below the open flow nozzles on both sides of the open flow filter plate and is connected to the external open flow pipeline. It is used for open flow liquid collection and liquid storage. The filtrate is collected into the external filtrate tank through two open flow pipelines.

[0005] The existing fixed open flow liquid receiving tank has the following defects: although the open flow liquid receiving tank is not directly below the filter plate, it is close to the two sides of the filter plate, when the filter plate is vibrated to unload the cake after the filtration is completed, the divergent force generated by the vibration of the filter plate to assist the unloading of the cake causes the filter cake on the two sides of the filter plate to easily collapse into the open flow liquid receiving tank, which affects the recovery rate of the filter cake or the purity rate of the filtrate; since the open flow liquid receiving tank is very long (more than 13 m long), it is very difficult to move the open flow liquid receiving tank before the filter plate is vibrated to unload the cake each time, and it is very troublesome to restore and affects continuous production; the open flow liquid receiving tank cannot meet the needs of the users of the open flow filter press to further improve the recovery rate of the filter cake or the purity rate of the filtrate; preventing the filter cake from collapsing into the open flow liquid receiving tank is a technical problem that people have been eager to solve but have failed to solve.

The rotating pipe joint 10 is used to connect the fixed pipe at one end and the rotating pipe at the other end, so that the rotating open flow liquid receiving tank 1 does not affect the fixed drain pipe flange 12 and the external open flow hose line.

[0030] The right half shaft with a hand wheel comprises a tubular right half shaft 3 and a tank hand wheel 4. The tank hand wheel 4 is welded to one end of the tubular right half shaft 3 to form the right half shaft with a hand wheel.

The filtrate of the multiple filter chambers flows out from the two rows of clear flow nozzles 21 (not hidden) on both sides of the clear flow filter plate 22 to the double clear flow liquid receiving grooves 1, and then is collected into the filtrate tank through the two external clear flow hose lines. The clearness of the filtrate can be directly observed to diagnose whether the filter cloth is damaged and leaks.
