When the filter press plates 15 are pressed and tightly attached, the reset plate 35 of the lower filter press plate 15 generates upward pressure on the upper filter press plate 15 under the action of the pressing spring 33, so that the contact pressure between the adjacent filter press plates 15 is enhanced.
A large amount of liquid is generated around the filter press plate 15 during the press filtration process, and the liquid enters the water containing space through the water permeable plate 34 and is discharged from the water outlet 37.
The filter press plate 15 may also include one or two wiper plates 36, typically with the wiper plates 36 being attached to the side walls of the bottom seal plate 31 on the feed and discharge sides of the filter press plate 15, respectively. The scraper 36 is used for scraping mud to separate the mud cake from the filter cloth.
The filter pressing assembly is a core component of the full-automatic filter press, and at least two or more filter pressing plates 15 are needed to work simultaneously to perform filter pressing operation. When the upper surface of each filter press plate 15 is covered with material, the cylinder 12 of the main press machine descends, and when each upper filter press plate 15 is pressed downwards, in the two adjacent filter press plates 15, the rubber sealing strip 32 at the bottom of the upper filter press plate 15, together with the filter cloth, the material to be treated in a solid-liquid mixed state, and the filter cloth of the lower filter press plate 15 are pressed downwards, the rubber sealing strip 32 of the upper filter press plate 15 drives the double-layer filter cloth to contact with the reset plate 35 in the groove 39 of the lower filter press plate 15, and the upward reaction force generated by the continuously pressing compression spring 33 pushes the upper filter cloth and the rubber sealing strip 32, so that the continuously pressing will be tighter and play a sealing role.

2. Lifting mechanism is connected to the filter-pressing subassembly, and its elevating movement is used for realizing two effects respectively: driving each filter press plate 15 to rise and generating uniform gaps between adjacent filter press plates 15; the respective filter presses 15 are driven downward and brought into close contact with each filter press 15.
There are a variety of structures for implementing the lifting function, the invention provides a concrete structure as follows:
The main press cylinder 12 rises to drive the press pressing table 13 to rise, the jacking cylinder 18 rises to drive the uppermost filter pressing plate 15 to move upwards, semicircular hanging plates 23 on two sides of the filter pressing plate 15 also move upwards to drive the next laminated filter plate to drive the next semicircular hanging plate to move upwards, all the filter pressing plates 15 are opened at one time, and the jacking cylinder 18 also has all the travel steps and then pressure maintaining.
The invention uses a plurality of hanging plates 23, each hanging plate 23 is crescent or semicircular, and the hanging plate 23 is a common part. A plurality of hanging plates 23 are connected and arranged between the adjacent filter pressing plates 15, so that the distance between the filter pressing plates 15 is kept within a certain interval range in a separated state. The hanging plates 23 are connected and arranged between the adjacent filter pressing plates 15, when each filter pressing plate 15 needs to be separated, a certain distance can be kept between every two filter pressing plates due to the length limitation of the hanging plates 23; the hanging plate 23 is provided so as not to affect the contact and separation actions of the filter press plate 15, and is only used for limiting the filter press plate 15 not to be separated at will when separated.
And a jacking cylinder 18 is also arranged, and the telescopic rod of the jacking cylinder is connected with a filter pressing plate 15 at the topmost layer. When the telescopic rod of the jack cylinder 18 is extended and contracted, the respective filter press plates 15 are driven to be lifted and lowered. Meanwhile, the filter press plates 15 are uniformly spaced apart while ascending and closely contact while descending. When the respective filter press plates 15 are at the time of producing uniform intervals, the upper surfaces of the respective filter press plates 15 can be distributed. The jacking cylinder 18 is used for realizing the distance adjustment between the filter pressing plates 15 through the telescopic action of the telescopic rod.
3. The press 1 is vertically arranged at the top of the filter pressing assembly and is used for generating downward pressure on the filter pressing assembly under the state that a plurality of filter pressing plates 15 are in close contact with each other so as to finish filter pressing of the distributed materials. The materials are solid-liquid mixture.
Specifically, the press 1 includes a press upper table 11 whose position is kept fixed; a main press cylinder 12 is provided and comprises a cylinder body and a telescopic rod, wherein the cylinder body is fixedly connected to a press upper platform 11, and the end part of the telescopic rod is connected with a press pressing table 13. The press 1 further comprises four press-filter plate guide posts 14, wherein the four press-filter plate guide posts 14 are vertically arranged around the main press cylinder 12 and are positioned between the upper press platform 11 and the bottom plate 17.
The press plate 15 may further include four guide sleeves 38, where each guide sleeve 38 has an annular structure, and is disposed on two sides of the bottom sealing plate 31, and is configured to be correspondingly sleeved on each press plate guide post 14.
2. The filter pressing process of the full-automatic filter press comprises the following steps:
As shown in fig. 1-2, the main press cylinder 12 drives the press platen 13 to press down onto the topmost press plate 15. The jacking cylinder 18 descends to drive all the filter press plates 15 to descend until all the filter press plates 15 are closed, and at the moment, the pressure of the press 1 is maintained for 10 minutes. In the pressure maintaining process, the filter-pressed wastewater is discharged to a total wastewater collecting pipe through a water outlet 37 on the side surface of the filter-pressing plate 15, the wastewater of the total wastewater collecting pipe directly flows into a wastewater collecting pit and is pumped to a wastewater treatment station for treatment, and the wastewater is discharged to a river channel or a city pipe network after reaching standards. After the pressure is maintained for 10 minutes, the main press cylinder 12 drives the press platen 13 to ascend until the travel is completed. The jacking cylinder 18 acts to jack up to drive each laminated filter plate 15 to be uniformly opened, the solid-liquid substance after press filtration becomes mud cake at the moment, each laminated filter plate 15 acts to rotate the filter cloth through the corresponding driving motor, the filter cloth moves forward towards the mud discharging direction, the mud cake is separated from the filter cloth and falls onto the belt conveyor after passing through the mud scraping plate 36 when going to the end, and the mud cake is sent out of the workshop until the mud cake collecting hopper, so far, the whole press filtration process is finished.
According to the invention, the rollers arranged on each layer of filter plates rotate to drive the filter cloth to rotate and are used for discharging mud, so that each layer can discharge mud simultaneously, and the overall mud discharging efficiency is high. Whereas the usual sludge outlet device is a continuous Z-folded filter cloth, the time for which the cake takes to transport and discharge this form of filter cloth is relatively long.
The press machine is a four-column press machine, and the material between filter cloth is forcedly dehydrated, and the maximum tonnage of the press machine can reach 320t, so the maximum dehydration rate can reach about 38 percent. The separated product generally comprises mud cake with water content of 38-45% and separated sewage. The purpose of solid-liquid separation is mainly to provide conditions for later mud cake landfill, incineration and organic fertilizer fermentation. Pollution of landfill sites and underground water can be reduced after sludge is dehydrated; the incineration cost can be reduced after the sludge is dehydrated; after the sludge is dehydrated, the fermentation speed of the organic fertilizer can be increased, the pollution to the environment and the atmosphere can be greatly reduced, and the long-term economic benefit and social benefit are realized.
In the prior art, the basic requirement on the filter cloth is that the filter cloth has better water permeability. The commonly used Z-shaped filter cloth arrangement form can use filter cloth with the length of 500 meters at one station, and the filter cloth needs to achieve certain strength because the span of the filter cloth is large and the filter cloth needs to bear certain pressure; however, in order to facilitate folding and to require a certain softness of the filter cloth, a certain required water permeability must be ensured. The requirements for the filter cloth are high in finishing and the cost is high. The filter cloth in the invention is a closed annular structure arranged around each filter pressing plate, and the length of each filter pressing plate is usually 1-2 m, so that the requirements on the pressure bearing capacity and softness of the filter cloth are reduced, and only the requirement on the water permeability is met.
