Description

Technical Field

[0001] The utility model relates to the technical field of quick-opening filter presses, and more specifically, to a vibration pull plate cake discharging device. Background Art

[0002] After the traditional filter press finishes filtering, it is necessary to manually or semi-automatically open the filter plates one by one to discharge the filter cake. This process not only takes time but also easily leads to production interruption, affecting the overall production efficiency. In addition, frequent manual operations increase the operation risks, and for sticky or difficult-to-discharge filter cakes, the processing capacity of traditional equipment is limited, often requiring additional manpower or chemical aids, increasing the production cost.

[0003] The past cake discharging devices often relied on hydraulic or mechanical drive systems and were realized through the following steps: When the filtration cycle is completed and the filtrate is completely discharged, the signal of the control system is triggered to drive the hydraulic cylinder or robotic arm to act; the telescopic movement of the hydraulic cylinder or robotic arm causes the pull plate device on the central beam to start, and the pull plate device connects all the filter plates through chains or steel wires; subsequently, the pull plate device starts to pull the filter plates orderly according to the preset program, causing separation between adjacent filter plates. This process requires precise control to avoid collisions between filter plates or damage to the filter cake; with the continuous action of the pull plate device, the filter plates are pulled open one by one to form enough space for the automatic shedding of the filter cake or the removal through auxiliary devices (such as vibrators or scrapers); after the filter plates are completely separated, the cake discharging process ends, and the pull plate device operates in reverse to close the filter plates again to prepare for the next filtration cycle; although the entire process of filter plate separation and closing realizes automation, limited by the drive technology and control accuracy at that time, there is still room for improvement in the operation speed and efficiency, and when dealing with sticky or difficult-to-shed filter cakes, the cake discharging effect and the separation stability of the filter plates face challenges.

[0004] In the prior art, during the use of quick-opening filter presses, there are problems of low cake discharging efficiency and complex operation when dealing with sticky or difficult-to-shed filter cakes; therefore, we make improvements and propose a vibration pull plate cake discharging device.

A vibrating reciprocating cylinder 4 is provided at the upper end of the air source pipe 3. A folding air bag 7 is provided at the outer end of the vibrating reciprocating cylinder 4. A positioning frame 8 is provided at the upper end of the folding air bag 7. Through slots 9 are respectively provided at both ends of the positioning frame 8. A flexible plate 17 is provided at the inner end of the through slot 9. A linkage rod 10 is provided at the upper end of the flexible plate 17. A slider 12 is provided at the front end of the linkage rod 10. A chute 11 is provided at the outer end of the slider 12. A linkage spring 13 is provided at the inner end of the chute 11. A connecting rod 14 is provided at the lower end of the flexible plate 17. An arc-shaped frame 15 is provided at the outer end of the connecting rod 14. A push rod 18 is provided at the rear end of the connecting rod 14. A linkage plate 16 is provided between the connecting rods 14.

[0029] The hook groove 6 is embedded and installed in the pull plate trolley 1. The positioning hook 5 is embedded in the hook groove 6. The upper end of the positioning hook 5 is fixedly connected to the linkage block 2.

[0030] Through the cooperation of the hook groove 6 and the positioning hook 5, the rapid and accurate positioning of the linkage block 2 and the pull plate trolley 1 is realized, ensuring the efficient start and positioning stability of the cake discharging device.

[0031] The inner end of the linkage block 2 is movably connected to the air source pipe 3. The upper end of the air source pipe 3 is movably connected to the vibrating reciprocating cylinder 4. The upper end of the linkage block 2 is fixedly connected to the positioning frame 8 through the folding air bag 7. The folding air bag 7 is wrapped around the outer end of the vibrating reciprocating cylinder 4.

[0032] The vibrating reciprocating cylinder 4 generates a reciprocating motion under the action of compressed air. Through the buffering of the folding air bag 7, the efficient resonance of the filter plate is realized, promoting the rapid falling off of the filter cake and improving the cake discharging efficiency.

[0033] The through slot 9 runs through the upper and lower ends of the positioning frame 8. The inner part of the through slot 9 is slidably connected to the flexible plate 17. The upper end of the flexible plate 17 is fixedly connected to the linkage rod 10.

[0034] The linkage between the flexible plate 17 and the linkage rod 10 enables the connecting rod 14 to achieve up and down displacement according to the movement of the pull plate trolley 1, squeezing the linkage spring 13, providing assistance for the stable operation of the vibration system and enhancing the vibration effect of the filter plate.

[0035] The lower end of the flexible plate 17 is fixedly connected to the connecting rod 14. The connecting rods 14 are fixedly connected through the linkage plate 16.

[0036] The arc-shaped frame 15 provides guidance for the connecting rod 14. The push rod 18 guides the displacement of the connecting rod 14 when the pull plate trolley 1 moves, ensuring the stable movement of the flexible plate 17 and the linkage rod 10 and realizing the effective drive of the vibration system.

[0037] Both ends of the connecting rod 14 are wrapped around the inner ends of the arc-shaped frame 15, the arc-shaped frame 15 is fixed to the lower end of the positioning frame 8, and there is a movable connection between the rear end of the connecting rod 14 and the push rod 18, and the push rod 18 moves inside the pull plate trolley 1.

[0038] When this application is in use: To facilitate the rapid separation of the filter plates, when the quick-pressure filter press discharges the cake, the filter plates move through the pull plate trolley 1, and the auxiliary cake discharging device starts to operate. The externally connected telescopic cylinder, under the action of compressed air, pushes the vibration reciprocating cylinder 4 to perform reciprocating motion, thereby causing the filter plates to generate intense resonance, prompting the cake to fall off. At the same time, single-side vibration, double-side vibration, and single-double vibration switching can be realized, which is used for working conditions where the cake is difficult to fall off and the material is sticky. And in the connection between the pull plate trolley 1 and the linkage block 2, the quick positioning of the hook groove 6 and the positioning hook 5 is adopted to ensure the quick positioning of the linkage block 2 and the pull plate trolley 1. After that, when the pull plate trolley 1 moves, the connecting rod 14 connected to the push rod 18 can move along the inside of the arc-shaped frame 15, driving the linkage rod 10 on the flexible plate 17 to move downward, squeezing the linkage spring 13, thus facilitating the movement of the linkage block 2 and the vibration reciprocating cylinder 4;

[0039] The introduction of the telescopic cylinder realizes the precise control of the vibration reciprocating cylinder 4, and single-side vibration, double-side vibration, or single-double vibration switching can be selected according to the characteristics of the cake, adapting to the cake discharging requirements under different working conditions.
