Description
Technical Field
The utility model relates to a pressure filter hydraulic system and pressure filter thereof belongs to pressure filter technical field.
Background
The filter press is intermittent pressure filtration equipment in the solid-liquid separation industry, and is widely applied to municipal environmental protection, food and beverage, chemical pharmacy, petrifaction, printing and dyeing, papermaking and other related industrial industries. When the filter press works, each filter plate is tightly pressed between the thrust plate and the pressing plate through the pressing oil cylinder, a filter chamber is formed between the filter plates, and the filter chamber is sealed under the thrust action of the pressing oil cylinder and keeps a certain pressing force. During filtering, the material is pumped into the filtering chamber by the feeding pump, solid particles are intercepted in the filtering chamber by the filter cloth to form a filter cake in the process that the material flows in the filtering chamber, and filtrate is discharged out of the filtering chamber through the filter cloth, so that solid-liquid separation is realized. In addition, the filter press is also provided with a plate turnover mechanism for receiving liquid when the plate turnover is closed during filter pressing and cloth washing, and the plate turnover is opened during cake unloading.
Conventional filter presses typically employ reciprocating plate puller motions such as those disclosed in patent applications publication nos. CN202237435U and CN201519504U to sequentially pull apart the filter plates and remove the cake. The traditional cake unloading method has long process time and low working efficiency. With the demand of people for the filter press to be increasingly large-sized, automatic and efficient, a mode of pulling a group of a plurality of filter plates to unload cakes by using a long-stroke large-cylinder-diameter oil cylinder once as disclosed in the patent application of the publication No. CN213100975U appears at present, but when a pump station of an original hydraulic system, such as the pump station disclosed in the publication No. CN 202223948, is used for driving the long-stroke large-cylinder-diameter oil cylinder, the telescopic speed of a cylinder rod is slow, the time for pressing and loosening the filter plates is long, the intermittent time and the production efficiency of the filter press are influenced, and the requirement of efficient production of users cannot be met. In addition, the space of the site limits the volume of the hydraulic oil tank, resulting in that the hydraulic oil tank cannot be designed large enough to naturally dissipate the heat of the hydraulic oil, thereby causing the oil temperature to be difficult to decrease. And thirdly, the large-displacement hydraulic pump and the high-power motor are high in manufacturing cost, so that the equipment cost of the filter press is increased.
