Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, and more specifically to a filter press which is convenient for replacing filter plates. Background Art

[0002] A filter press is a filtering device for solid-liquid separation. Its working principle is to use a special filter medium to apply a certain pressure to the object, so that the liquid can be dialyzed out to achieve the effect of solid-liquid separation. A filter press is generally composed of a compression plate, a thrust plate, a filter plate, a hydraulic cylinder, a main beam, a transmission and a pulling device. When the hydraulic cylinder piston pushes the head plate to make the filter plate press the adjacent filter plate to form a filter chamber, the feed pump sends the mud into the filter chamber, the water passes through the filter cloth and is discharged through the drain port, and the solid mud forms a filter cake in the filter chamber. When the mud fills the filter chamber, the high-pressure pump is used to continue to pressurize the mud to separate the solid and liquid in the filter chamber.

[0003] The filter plate of the filter press plays a vital role in the operation of the filter press. It can increase the filtration area: the filter plate can effectively increase the area of ​​the filter chamber wall, thereby increasing the contact area between the filter cloth and the mixed liquid, so that more liquid can be filtered through the filter cloth, thereby improving the filtration efficiency of the filter press; divide the filter chamber and store the filter cake: the filter plate divides the filter chamber into filter cavities, each of which can be filtered independently. In addition, the two sides of the filter plate are usually designed to be concave. This design allows the space between the two filter plates to be used to store the filter residue intercepted by the filter cloth, that is, the filter cake. This structure is not only conducive to the storage of the filter cake, but also when there are more filter cakes, the blind spot design at the bottom of the filter plate can increase the friction between the filter plate and the filter cake, making the filter cake more stable; transfer pressure: in the process of filtration, in order for the filtrate to effectively percolate out of the filter cloth, an effective pressure difference needs to be formed on both sides of the filter cloth. At this time, the filter plate, as a transmitter of pressure provided by the hydraulic pressure, transmits the pressure to the liquid, so that the liquid in the solid-liquid mixture can effectively percolate out of the filter cloth.

[0004] Although the filter plate of the filter press plays a very important role, the filter plate of the filter press is relatively heavy. Replacing the filter plate may take more time and effort, thereby reducing the efficiency of replacing the filter plate of the filter press. Utility Model Content
