Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic systems, in particular to a hydraulic system and a chemical fiber grade titanium dioxide filter press device. Background Art

[0002] The hydraulic system is the central component of the chemical fiber grade titanium dioxide filter press device, mainly composed of power elements, actuators, control elements and auxiliary elements. The power element is mainly a hydraulic pump, the actuator is usually a hydraulic cylinder, the control element includes various hydraulic valves, and the auxiliary elements include hydraulic oil tanks, filters, pipelines, pressure gauges, etc. The chemical fiber grade titanium dioxide filter press device is usually composed of the filter press body, filter plates, filter frames, feeding devices, and unloading devices. The filter press body is a frame structure that supports and accommodates various components; the filter plates and filter frames are arranged alternately, and the surface of the filter plates is usually covered with filter cloth. Together, they form a filter chamber for achieving solid-liquid separation; the feeding device is responsible for conveying the suspension of chemical fiber grade titanium dioxide into the filter chamber; the unloading device is used to remove the filter cake from the filter plates after the filtration is completed. The suspension of chemical fiber grade titanium dioxide is fed into the filter chamber composed of filter plates and filter frames through the feeding device. During the filtration process, the filter plates are pressed against each other under external pressure, squeezing the suspended liquid in the filter chamber. The liquid is squeezed out through the filter cloth, while the titanium dioxide particles are trapped in the filter chamber, forming a filter cake, thus achieving solid-liquid separation. When the filtration is complete, the discharge device is activated to peel the filter cake from the filter plates and discharge it.

[0003] However, when the existing hydraulic system and chemical fiber grade titanium dioxide filter press device are in use, air is easily mixed into the hydraulic oil of the hydraulic system, which is difficult to discharge in time, resulting in problems such as oil emulsification, system vibration and noise, affecting its performance and life.

[0023] A chemical fiber grade titanium dioxide filter press device comprises a hydraulic system.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] This hydraulic system and chemical fiber grade titanium dioxide filter press device are provided with an air extraction mechanism and a defoaming mechanism, etc., and when in use, under the action of the circulation pump, the hydraulic oil can enter the circulation pump through the oil extraction pipe and enter the oil cylinder through the oil inlet pipe. The hydraulic oil in the oil cylinder can return to the temporary storage box in the oil tank through the return oil pipe for temporary storage. At the same time, when the hydraulic oil enters the fixed box through the oil inlet pipe, it can impact the side wall of the rotary fan, thereby pushing the rotary fan to rotate. When the rotation of the rotating rod drives the cam to rotate, when the tip of the cam abuts against the side wall of the push block, it can drive the rack to move through the connecting frame. At the same time, the reset spring is compressed. When the tip of the cam passes over the side wall of the push block, the rack can move and reset under the action of the reset spring. When the second guide plate is moved back and forth, the second curved plate is driven to move back and forth along the side wall of the first guide plate, and the second curved plate is driven to move by the first spring, thereby driving the rotating roller to roll on the top of the filter cloth, and through the first solenoid valve, the storage box is moved back and forth. The temporarily stored hydraulic oil flows quantitatively to the top of the filter cloth, and under the action of the rotating roller, the hydraulic oil on the filter cloth can be spread and squeezed, and then reaches the bottom of the vacuum box through the filter cloth and the hollow plate. At the same time, it can push the bubbles to slide along the filter cloth to the side wall of the first curved plate and squeeze and break them. Moreover, when the connecting frame moves back and forth, it can drive the pushing pin to slide back and forth in the slide groove through the mounting block, thereby pushing the rotating plate and the third curved plate to swing back and forth along the rotating pin. When the second tapered rod abuts against the side wall of the protrusion, the piston can be pushed to move in the direction close to the connecting pipe through the connecting rod. At the same time, the fourth spring is compressed. When the second tapered rod passes over the protrusion, the piston can move back and forth in the direction away from the connecting pipe under the action of the fourth spring, and so on. When the piston moves in the direction away from the connecting pipe, negative pressure is generated in the connecting pipe. At the same time, the first one-way valve opens and the second one-way valve closes. At this time, the air in the suction box can enter the connecting pipe through the suction pipe. When the piston moves in the direction close to the connecting pipe, the air in the connecting pipe can be squeezed out. At the same time, the first one-way valve closes and the second one-way valve opens. At this time, the air in the connecting pipe can be discharged through the exhaust pipe. This reciprocating process can discharge the air in the suction box, thereby facilitating the removal of bubbles in the hydraulic oil and ensuring its effectiveness and service life. In addition, when exhausting through the exhaust pipe, the cover plate can be pushed to rotate upward along the second rotating shaft. When the second rotating shaft rotates,It can drive the pointer to rotate, and by observing the scale mark indicated by the pointer through the visual sensor, the air discharge status in the vacuum box can be determined.

[0026] This hydraulic system and chemical fiber grade titanium dioxide filter press device, by setting a moving mechanism and a water supply mechanism, etc., and by inserting a plurality of rectangular tubes through the oil tank, can achieve a good heat dissipation effect on the hydraulic oil in the oil tank, and when the connecting frame moves, the mounting plate can be driven to move through the connecting plate, and when the third push rod abuts against the side wall of the triangular plate, the movable cover can be pushed to slide in the rectangular tube, and at the same time, the third spring is compressed. When the third push rod passes over the triangular plate, the movable cover can be moved and reset under the action of the third spring, and so on and so forth, so that the movable cover can be moved and reset. It moves back and forth in the rectangular tube. At this time, the bristles can clean the inner wall of the movable cover. At the same time, the sponge can slide on the inner wall of the rectangular tube. The cooling water in the water tank can enter the movable cover through the water supply pipe and the hose, and enter the sponge through the through hole to be absorbed and smeared on the inner wall of the rectangular tube. Moreover, when the movable cover and the sponge move back and forth, the external air can be sucked into the rectangular tube, thereby making the heat dissipation efficiency of the rectangular tube higher and the effect better, and then making the cooling efficiency of the hydraulic oil in the oil tank higher and the effect better, thereby ensuring the use effect and life of the hydraulic system.

When the second tapered rod 814 abuts against the side wall of the protrusion 807, the piston 707 can be pushed by the connecting rod 801 to move in the direction close to the connecting tube 703. At the same time, the fourth spring 805 is compressed. When the second tapered rod 814 passes over the protrusion 807, the piston 707 can be moved and reset in the direction away from the connecting tube 703 under the action of the fourth spring 805. This reciprocating process can make the piston 707 move back and forth in the working tube 706.

[0064] A chemical fiber grade titanium dioxide filter press device comprises a hydraulic system.

[0065] Working principle: When in use, under the action of the circulating pump 101, the hydraulic oil can enter the circulating pump 101 through the oil extraction pipe 106 and enter the oil cylinder 103 through the oil inlet pipe 104. The hydraulic oil in the oil cylinder 103 can return to the temporary storage box 10 in the oil tank 102 through the return oil pipe 105 for temporary storage. At the same time, when the hydraulic oil enters the fixed box 506 through the oil inlet pipe 104, it can impact the side wall of the rotary fan 511, thereby pushing the rotary fan 511 to rotate. When the rotation of the rotating rod 509 drives the cam 510 to rotate, when the tip of the cam 510 abuts against the side wall of the pushing block 508, it can drive the rack 504 to move through the connecting frame 507. At the same time, the return spring 505 is compressed. When the tip of the cam 510 passes over the side wall of the pushing block 508, the rack 504 can move and reset under the action of the return spring 505, and so on and so forth, which can make the gear 501 rotate back and forth.

[0066] When the gear 501 rotates, the rotating disk 410 can be driven to rotate back and forth through the first rotating shaft 409. When the side wall of the first tapered rod 411 abuts against the end of the second push rod 408, the push plate 407 can be pushed to move toward the fixed plate 401. At the same time, the second spring 404 is compressed. When the first tapered rod 411 passes over the end of the second push rod 408, the push plate 407 can be moved and reset under the action of the second sleeve rod 403. This reciprocating movement can make the push plate 407 reciprocate and, at the same time, push the first push rod 406 to slide back and forth in the inclined slot 405, thereby driving The movable plate 305 slides back and forth along the side wall of the first guide rod 304, and drives the second curved plate 308 to move through the first spring 311, etc., thereby driving the rotating roller 309 to roll on the top of the filter cloth 302. Through the first solenoid valve 12, the hydraulic oil temporarily stored in the temporary storage box 10 flows quantitatively to the top of the filter cloth 302. Under the action of the rotating roller 309, the hydraulic oil on the filter cloth 302 can be flattened and squeezed, and then reaches the bottom of the vacuum box 11 through the filter cloth 302 and the hollow plate 301. At the same time, it can push the bubbles to slide along the filter cloth 302 to the side wall of the first curved plate 303 and squeeze and crush them.

[0067] Moreover, when the connecting frame 507 moves back and forth, the pushing pin 812 can be driven by the mounting block 811 to slide back and forth in the slide groove 810, thereby pushing the rotating plate 809 and the third curved plate 813 to swing back and forth along the rotating pin 808. When the second tapered rod 814 abuts against the side wall of the protrusion 807, the piston 707 can be pushed by the connecting rod 801 to move toward the connecting pipe 703. At the same time, the fourth spring 805 is compressed. When the second tapered rod 814 passes over the protrusion 807, the piston 707 can be moved and reset in the direction away from the connecting pipe 703 under the action of the fourth spring 805. This reciprocating process can make the piston 707 move back and forth in the working tube 706.

[0068] When the piston 707 moves in the direction away from the connecting pipe 703, negative pressure can be generated in the connecting pipe 703. At the same time, the first one-way valve 702 is opened and the second one-way valve 705 is closed. At this time, the air in the vacuum box 11 can enter the connecting pipe 703 through the vacuum pipe 701. When the piston 707 moves in the direction close to the connecting pipe 703, the air in the connecting pipe 703 can be squeezed. At the same time, the first one-way valve 702 is closed and the second one-way valve 705 is opened. At this time, the air in the connecting pipe 703 can pass through The exhaust pipe 704 is used to discharge air, and the air in the vacuum box 11 can be discharged in this reciprocating manner, thereby facilitating the removal of bubbles in the hydraulic oil, ensuring its effectiveness and life. Moreover, when exhausting air through the exhaust pipe 704, the cover plate 708 can be pushed to rotate upward along the second rotating shaft 902. When the second rotating shaft 902 rotates, the pointer 904 can be driven to rotate. Moreover, the air discharge status in the vacuum box 11 can be determined by observing the scale mark 905 indicated by the pointer 904 through the visual sensor 906.

[0069] After the air is exhausted, the second solenoid valve 17 can be opened to allow the hydraulic oil in the air extraction box 11 to enter the oil tank 102;

[0070] By inserting a plurality of rectangular tubes 13 through the oil tank 102, a good heat dissipation effect can be achieved for the hydraulic oil in the oil tank 102. Moreover, when the connecting frame 507 moves, the mounting plate 602 can be driven to move through the connecting plate 601. When the third push rod 603 abuts against the side wall of the triangular plate 604, the movable cover 14 can be pushed to slide in the rectangular tube 13. At the same time, the third spring 605 is compressed. When the third push rod 603 passes over the triangular plate 604, the movable cover 14 can be moved and reset under the action of the third spring 605. This reciprocating process can make the movable cover 14 move back and forth in the rectangular tube 13. When the movable cover 14 is moved back and forth, the bristles 16 can clean the inner wall of the movable cover 14. At the same time, the sponge 15 can slide on the inner wall of the rectangular tube 13. The cooling water in the water tank 202 can enter the movable cover 14 through the water supply pipe 203 and the hose 204, and enter the sponge 15 through the through hole 201 to be absorbed and smeared on the inner wall of the rectangular tube 13. Moreover, when the movable cover 14 and the sponge 15 move back and forth, the external air can be sucked into the rectangular tube 13, thereby making the heat dissipation efficiency of the rectangular tube 13 higher and the effect better, thereby making the cooling efficiency of the hydraulic oil in the oil tank 102 higher and the effect better, thereby ensuring the use effect and life of the hydraulic system.
