Description

Combined mechanism of vibrating cake discharging device and plate pulling device and filter press thereof

Technical Field

The utility model relates to a combined mechanism of a vibrating cake discharging device and a plate pulling device and a filter press thereof, belonging to the technical field of filter presses.

Background

The filter press is a main filtering device in the solid-liquid separation industry and is widely used in municipal environmental protection, food and beverage, chemical pharmacy, petrochemical industry, printing and dyeing industry, papermaking industry and other related industries. When the filter press works, each filter plate is pressed between the thrust plate and the pressing plate through the oil cylinder, so that a filter chamber is formed between each filter plate, solid particles are trapped in the filter chamber by filter cloth to form a filter cake in the flow process of the filter chamber after the material is pumped into the filter chamber, and filtrate is discharged out of the filter chamber through the filter cloth, so that solid-liquid separation of the material is realized.

After the filtration is completed, the compacting plates are retreated, the filter plates are sequentially pulled by the plate pulling device to discharge cakes, and the filter cloth is vibrated by the vibration cake discharging device to assist cake discharging in the process of pulling the filter plates, so that the filter cakes adhered on the filter cloth fall fully. For example, the patent with publication number CN212818345U provides a filter cloth supporting mechanism and cake unloading mechanism, which can shake the supporting rod suspending the filter cloth by a shaking cylinder, so that the filter cloth shakes, and the filter cake adhered on the filter cloth shakes off. The vibrating cylinder is arranged on the portal frame, the portal frame moves along the guide rail on the main beam, the bottom of the portal frame is fixedly connected with the plate pulling device, and the portal frame is driven to synchronously move through the plate pulling device.

When the filtering efficiency of the filter cloth is reduced, the filter cloth can be washed, the cloth washing device is generally arranged on the filter plate in a crossing manner, and the cloth washing device is driven by the driving mechanism to move along the guide rail on the main beam so as to clean the filter cloth. For example, patent publication No. CN213100970U discloses a traveling mechanism for a filter cloth cleaning device of a filter press, in which a plate puller pulls a filter plate to a cleaning position during cloth cleaning, and then the filter cloth is cleaned by the cleaning device.

When the existing filter press is equipped with a rapping cake discharging device, the structure is usually adopted, for example, in the patent with the publication number of CN212818345U, wherein the rapping cake discharging device is fixedly connected with a plate pulling device. If the cloth washing device is equipped, the frame of the cloth washing device and the frame of the rapping cake discharging device are all arranged on the filter plate in a crossing way, so that the rapping cake discharging device and the cloth washing device interfere with each other in the working process, the filter press is difficult to be equipped with the rapping cake discharging device and the cloth washing device at the same time, and the working efficiency of the filter press is affected.

Specifically, the driving member 312 is an electric push rod or an air cylinder, and the driving member 312 may be disposed at a lower portion of the supporting vertical beam of the first portal frame 110.

The combined mechanism of the rapping cake discharging device and the plate pulling device provided by the utility model can detachably connect the rapping cake discharging device 100 with the plate pulling device 200, and when the cloth washing device is required to wash the filter cloth, the plate pulling device 200 is separated from the rapping cake discharging device 100, so that the rapping cake discharging device 100 is stopped at a position which is not interfered with the cloth washing device and the plate pulling device 200, for example, at the end of an oil cylinder seat, and then the filter plate to be washed can be pulled away through the plate pulling device 200, and meanwhile, the cloth washing device moves towards the filter plate to wash the filter cloth. Thus, the mutual interference of the rapping cake discharging device 100 and the cloth washing device is avoided, so that the rapping cake discharging device and the cloth washing device can smoothly complete respective operation processes, and the filter press has the functions of rapping cake discharging and cloth washing.

As shown in fig. 6 and 7, the present utility model further provides a filter press, which comprises a combination mechanism of the rapping cake discharging device and the plate pulling device, and further comprises two main beams 400 and a plurality of filter plates 500, wherein each filter plate 500 is slidably arranged between the two main beams 400, the two main beams 400 are respectively provided with a first guide rail 410, the plate pulling device 200 and a sliding seat 130 of the first portal frame 110 for supporting the bottom of the vertical beam are slidably mounted on the first guide rail 410, and the front side and the rear side of each filter plate 500 are respectively provided with a filter cloth 510;

the rapping element 120 is used for rapping the filter cloth 510, and the plate puller 200 is used for pulling each filter plate 500 in turn. The rapping element 120 may be mounted on the cross beam of the first gantry 110 for intermittent rapping of the filter cloth 510 downwards, the rapping element 120 being located directly above the filter plate 500 pulled by the plate puller 200 when the slide 130 supporting the bottom of the vertical beam of the first gantry 110 is coupled to the plate puller 200 by means of a coupling mechanism.

Further, the filter press provided by the utility model further comprises a cloth washing device 600, so that the filter press has the functions of beating, cake discharging and cloth washing. The cloth washing apparatus 600 includes a second gantry 610 and a cloth washing member 620 mounted on the second gantry 610; the two main beams 400 are further provided with second guide rails 420 respectively, the supporting vertical beams of the second portal frame 610 are slidably mounted on the second guide rails 420, and the horizontal distance between the second guide rails 420 and the main beams 400 arranged on the same side main beam 400 is greater than the horizontal distance between the first guide rails 410 and the main beams 400. The cloth washing device 600 is driven by the driving mechanism to move along the second guide rail 420, so that the filter cloth 510 on the corresponding filter plate 500 can be washed, and the work of the plate pulling device 200 is not interfered.

Specifically, one end of the main beam 400 is provided with a thrust plate 710, the other end of the main beam 400 is provided with a compression plate 720 and a cylinder seat 731, the cylinder 730 is mounted on the cylinder seat 731, the thrust plate 710, the cylinder seat 731 and the main beam 400 are fixedly connected, the compression plate 720 is slidably connected with the main beam 400, and the compression plate 720 is fixedly connected with a cylinder rod of the cylinder 730. When the rod of the cylinder 730 is extended, the pressure plate 720 is pushed toward the thrust plate 710, and the filter plates 500 located between the pressure plate 720 and the thrust plate 710 are pressed against each other to form a filter chamber. After the filtration is completed, the cylinder 730 is retracted to drive the hold-down plate 720 away from the thrust plate 710. Then, plate pulling, beating, cake unloading and cloth washing operations can be performed.

The plate puller 200 is provided with plate pulling claws, and the plate pulling claws clamp the filter plate handles of the filter plates 500 during plate pulling, so that the filter plates 500 can be driven to move along the first guide rail 410 through the plate puller 200. After the cylinder 730 pulls the hold-down plate 720 to the cylinder seat 731, the plate puller 200 can reciprocate to sequentially pull each filter plate 500.

After the filter plates 500 are pulled apart, a large portion of the filter cake can naturally fall out from between the filter plates 500, but a small portion still adheres to the filter cloth 510. In order to sufficiently clean the filter cake adhered to the filter cloth 510, a rapping cake discharging operation is required. The rapping cake discharging mode is a common mode, and the rapping cake discharging operation is usually required after the pulling plate is finished. The cloth washing mode is started according to the cleaning degree of the surface of the filter cloth, and the two modes are switched through the PLC control cabinet.

The working processes of the vibration cake discharging working mode and the cloth washing working mode are specifically as follows:

(1) The working mode of shaking and cake discharging is as follows:

as shown in fig. 6, the cloth washing apparatus 600 is stopped at the thrust plate 710 end to avoid interfering with the operation of the rapping cake discharging device 100. Then, the plate pulling device 200 is moved to be close to the sliding seat 130 of the shaking and cake discharging device 100, the mandrel 330 is inserted into the shaft sleeve 320, the bolt 311 is inserted into the through holes on the shaft sleeve 320 and the mandrel 330 in a downward motion, and the connection between the shaft sleeve 320 and the mandrel 330 is realized, so that the shaking and cake discharging device 100 and the plate pulling device 200 are locked together, and the shaking and cake discharging device 100 synchronously moves along with the plate pulling device 200.

The plate puller 200 moves toward the thrust plate 710 together with the rapping cake discharging device 100, the plate puller 200 moves to the first filter plate and holds the first filter plate, and then the plate puller 200 moves with the first filter plate toward the hold-down plate 720. After the first filter plate is pulled apart, most of the filter cake between the first filter plate and the next filter plate falls under the action of gravity, but a part of the filter cake still adheres to the filter cloth 510. In order to sufficiently separate the filter cake adhered to the filter cloth 510, the rapping element 120 of the rapping device 100 starts to operate to rapp the filter cloth so that the filter cake adhered to the filter cloth 510 is sufficiently separated in the process that the plate pulling device 200 moves with the filter plate in the direction of the pressure plate 720. Then repeating the above actions, pulling the next filter plate open and vibrating until the cake unloading of all filter plates is completed.

The plate puller 200 and the cloth shake-out apparatus are both positioned on the first rail 410, and in order to bring the plate puller 200 sufficiently close and grip the filter plate to be pulled apart, the plate puller 200 is typically positioned between the end of the thrust plate 710 and the shake-out apparatus 100.

(2) Cloth washing working mode:

when the filter cloth needs to be cleaned, as shown in fig. 7, the plate pulling device 200 drives the rapping cake discharging device 100 to move to a limiting position at the end of the oil cylinder seat 731, and the plate pulling device 200 is separated from the sliding seat 130 of the shaking cake discharging device by combining the action of the mechanism. Then, the plate puller 200 works independently, the pulling plate is moved towards the thrust plate 710, and the cloth washing device 600 moves towards the pressing plate 720 to be close to the filter plate to be washed, so that the filter cloth on the filter plate can be washed by the cloth washing device 600. The above-described actions are repeated until all filter plate washings are completed. The cloth washing element 620 of the cloth washing apparatus 600 can be lifted up and down to wash the filter cloth comprehensively.

In summary, when the rapping and cake discharging mode is in operation, the plate pulling device 200 is combined with the rapping and cake discharging device 100, and the filter cloth 510 can be rapped by the rapping and cake discharging device 100 during the plate pulling process. When the cloth washing mode works, the plate pulling device 200 is separated from the rapping cake discharging device 100, the rapping cake discharging device 100 is stopped at a position which is not mutually interfered with the cloth washing device 600 and the plate pulling device 200, namely, the filter plate 500 to be washed can be pulled out through the plate pulling device 200, meanwhile, the cloth washing device 600 moves towards the filter plate 500 to perform the washing operation of the filter cloth 510, and thus, the filter press has the functions of rapping cake discharging and cloth washing.

Specifically, the filter cloth 510 is disposed on both front and rear sides of the filter plate 500 by a supporting device, as shown in fig. 3 and 4, and in one embodiment, the supporting device includes a cloth rail 810, two fixing seats 820, two guide bars 830, and two springs 840.

The rapping element 120 typically employs a cylinder, the cylinder rod of which extends downwards. The cylinder works under the control of the reversing valve, the cloth hanging rod 810 is hit according to the PLC program set times, when the cylinder rod of the cylinder extends downwards, the cylinder rod hits the cloth hanging rod 810 downwards, the cloth hanging rod 810 moves downwards to enable the spring 840 to compress and enable the upper end of the filter cloth 510 to move downwards, the filter cloth 510 is in a loose state, then the cylinder rod of the cylinder is retracted, the spring 840 extends under the action of self elasticity, the cloth hanging rod 810 is enabled to bounce upwards, the filter cloth 510 is driven to move upwards to reset, and in the process that the filter cloth 510 moves up and down along with the cloth hanging rod 810, a filter cake adhered on the filter cloth 510 is shaken off.

Specifically, the hanging manner of the filter cloth 510 on the cloth hanging rod 810 can be a crossed hinge type or a cloth hanging pin type.

As shown in fig. 8, the cross hinge type means that a cloth hanging sleeve belt 511 is provided at the upper end of each side of the filter cloth 510, and the cloth hanging sleeve belt 511 is capable of allowing the cloth hanging rod 810 to pass through in the axial direction, and the cloth hanging rod 810 crosses through the cloth hanging sleeve belts on the filter cloths 510 at both sides, forming a cross hinge type cloth hanging form.
