[0010] The beneficial effects of the present invention are: 1. This type of multi-feed quick-opening plate filter press can achieve the effects of multi-feed and secondary pressing. After the equipment enters the compression and pressure holding stage, multiple feed pipes on the end main beam support side feed at the same time, so that the filtrate quickly fills the filter chamber of the filter plate body in the A zone and the filter chamber of the B zone. At the same time, the water inlet valve of the diaphragm pressing air intake assembly is opened, and then the pressure pump connected to the air pipeline is turned on. Then the pressurized pressing water enters each diaphragm lining through the middle diaphragm air inlet port to perform secondary pressing on the filter plate. Since the middle pressing pipe of the middle thrust plate is connected to the left and right sides, the diaphragm pressing plates on the left and right sides are all fed with water for pressing together, which greatly reduces the time.

This multi-head feeding quick-opening plate filter press is provided with a transmission shaft, a small sprocket, a double-speed chain tensioner, a double-speed sprocket, a double-speed chain, a driving reducer, a driving reducer sprocket, a double-row chain, a one-time pulling limit sensor and a compression limit sensor. The double-speed chain tensioner can adjust the chain tension of the double-speed chain after the double-speed chain is installed and fixed. The driving reducer drives the driving reducer sprocket to rotate. The driving reducer sprocket rotates and drives the transmission shaft to rotate through the double-row chain. When the double-speed chain moves, it can drive the cylinder seat connecting the plate to move together, and then drive the compression plate assembly and the diaphragm filter plate assembly to cooperate with the compression cylinder to realize the compression and filtration work. The one-time pulling limit sensor and the compression limit sensor are both limit sensors for the cylinder seat connecting the plate, which are used to accurately ensure that the cylinder seat assembly fixed to the cylinder seat connecting plate can accurately move to the corresponding position to ensure that the pin can be inserted into the pin hole of the left and right main beam assemblies.

[0012] 3. This multi-feed quick-opening pull-plate filter press is provided with a filter plate body, a water outlet tap, a filter plate collecting hole, a zone A filter chamber, a zone B filter chamber, a zone A feed port and a zone B feed port. The filter plate collecting hole is a collecting hole that is interconnected with the collecting holes on other plates, which fully ensures that the filtrate flows out smoothly through the water outlet tap. The filter plate collecting trough is the collecting trough of the filter plate body, which interconnects the filter chamber and the filter plate collecting hole. The porous structure of the collecting trough ensures that the filtrate is fully filtered out. The zone A filter chamber and the zone B filter chamber are the main filter chambers, which are connected to each other by the filter chamber channels up and down. This structure fully ensures that when a single feed port is affected by uncontrollable factors such as filter cloth, resulting in the feed port on one side being unable to inject liquid into the filter chamber, the feed port on the other side can still fill the area of ​​the zone A filter chamber and the zone B filter chamber, avoiding the occurrence of blockage and other situations that lead to a reduction in filtration area and a decrease in output.

[0013] 4.

[0023] The oil cylinder assembly includes two floating oil cylinder bodies 4.4, both of which are equipped with a latch 4.1 oil cylinder barrel 4.3 by bolts, a latch oil cylinder rod 4.2 is provided on the latch 4.1 oil cylinder barrel 4.3, and the latch oil cylinder rod 4.2 is fixed with the latch 4.1 by bolts, and a clamping oil cylinder 4.7 is fixed with bolts to the floating oil cylinder body 4.4, and a synchronous oil return pipe 4.5 and a synchronous oil inlet pipe 4.6 are provided between the two floating oil cylinder bodies 4.4; By arranging a floating oil cylinder body 4.4, a bolt 4.1 oil cylinder barrel body 4.3, a bolt oil cylinder rod 4.2, a bolt 4.1, a clamping oil cylinder 4.7, a synchronous oil return pipe 4.5 and a synchronous oil inlet pipe 4.6, the synchronous oil return pipe 4.5 cooperates with the synchronous oil inlet pipe 4.6, and the oil circuit of the hydraulic system is evenly distributed to the left and right bolt 4.1 oil cylinders through a three-way joint.

[0024] How it works S1, double-head clamping: The driving reducer 1.2 of the double-head of the equipment is started at the same time to drive the double-speed chain 1.8 to pull the cylinder seat assembly 4 to move toward the middle thrust plate 10. At this time, the clamping cylinder 4.7 in the cylinder seat assembly 4 is in a retracted state, thereby driving the filter plate body 8.10 to move inward and close together; When the filter plate body 8.10 moves to the position of the clamping limit sensor 1.11, the reducer 1.2 is driven to stop working. At this time, the plug 4.1 is pushed out synchronously through the synchronous oil inlet pipe 4.6, and inserted into the main beam pin hole for fixing. Note that the hole size of the main beam plug 4.1 is larger than the diameter of the plug 4.1, so as to ensure that the cylinder seat and the main beam plug 4.1 are fixed after reaching the limit. After the above operation, the cylinder seat is fixed to the left and right main beams by the action of the latch 4.1. At this time, the clamping cylinder 4.7 fixed on the floating cylinder body 4.4 starts to work, pushing the clamping plate body 7.5 to continue to move inward, pressing the filter plates against each other, and then maintaining the pressure.

[0025] S2, Multi-head feeding: After the equipment enters the compression and pressure-maintaining stage, multiple feed pipes 7.4 on the side of the end main beam support 2 feed simultaneously, so that the filtrate quickly fills the zone filter chamber of the filter plate body 8.10 and the zone B filter chamber 8.9; After sufficient feeding is achieved, no large water flow will flow out of the water outlet tap 8.1, and the feeding is stopped, and the feeding valves connected to the feeding hose 7.3 are all closed; S3, diaphragm secondary pressing: The water inlet valve of the diaphragm pressing air inlet assembly 12 is opened, and then the pressure pump connected to the air pipeline is turned on, and then the pressurized pressing water enters each diaphragm lining through the middle diaphragm air inlet 8.11 to perform secondary pressing on the filter plate. Since the middle pressing pipe of the middle thrust plate 10 is connected to both the left and right sides, the diaphragm pressing plates on the left and right parts are all filled with water for pressing together, which greatly reduces the time.

[0026] S4, pull open at one time; When the secondary pressing is completed, the connected pressing pump of the diaphragm pressing air inlet assembly 12 is closed.

[0027] Then the clamping cylinder 4.7 fixed on the floating cylinder body 4.4 starts to work, pulling the clamping plate body 7.5 to move outward to loosen the filter plates; then at this time, the latch pin 4.1 is synchronously retracted through the synchronous oil inlet of the synchronous return oil pipe 4.5 and pulled out from the main beam pin hole.

[0028] The double-headed driving reducer 1.2 of the equipment is started at the same time to drive the speed chain 1.8 to pull the cylinder seat assembly 4 to move back to the middle thrust plate 10. At this time, the pressing cylinder 4.7 in the cylinder seat assembly 4 is in a retracted state, thereby driving the diaphragm filter plate assembly 8 and other filter plates to start moving backwards and spaced in sequence; When the filter plate body 8.10 moves to the limit sensor 1.10, the reducer 1.2 is driven to stop working. At this time, the pin 4.1 is pushed out synchronously through the synchronous oil inlet pipe 4.6, and inserted into the main beam pin hole for fixing. The hole size of the pin 4.1 of the main beam is larger than the diameter of the pin 4.1, so as to ensure that the cylinder seat and the main beam pin 4.1 are fixed after reaching the limit, and then the filter plate and filter plate space are cleaned.

[0029] Repeat this cycle.
