A vibratory unloading device for a plate and frame filter press

Abstract

This invention discloses a vibratory unloading device for a plate and frame filter press, comprising a supporting beam, a plate and frame, a moving assembly, and a vibrating assembly. The plate and frame slide on the supporting beam. The moving assembly includes a guide rail, a pulling plate trolley, a transmission component, and a push plate arm. Under external force, the transmission component drives the pulling plate trolley to reciprocate along the guide rail, causing the push plate arm to reciprocate and move the plate and frame on the supporting beam. The vibrating assembly includes a lifting component and a vibrator. Under external force, the lifting component drives the vibrator to reciprocate up and down, thereby ejecting one end of the plate and frame upward and then swinging it freely downward. The lifting component drives the vibrator upward, pushing one end of the plate and frame upward rapidly and then swinging it freely downward. The other end of the plate and frame is positioned on the supporting beam, and the plate and frame swing about the end that abuts the supporting beam. During multiple consecutive lifting and vibrating processes, the plate and frame are subjected to vibration force and its own downward swinging force, causing the filter cake residue attached to the plate and frame to separate quickly.

Description

Technical Field

[0001] This invention relates to the field of plate and frame filter press unloading technology, and specifically to a vibratory unloading device for a plate and frame filter press. Background Technology

[0002] A plate and frame filter press is a device used for chemical dewatering. It consists of multiple interconnected plates and frames that separate moisture from materials by applying pressure. The resulting filter cake residue adheres to the plates and frames and needs to be cleaned and collected. In the sulfuric acid processing area of ​​copper smelting, the sulfidation reaction liquid in the arsenic removal system is separated into solid and liquid components using a plate and frame filter press. After filtration, the filter cake is bagged and weighed using a ton bag packaging machine before being transported to a rigid landfill for disposal. During the filtration of arsenic sulfide slag, some hydrogen sulfide gas is released. When manually cleaning the filter cake residue, the hydrogen sulfide gas can easily cause poisoning to personnel. Furthermore, the arsenic sulfide slag is highly viscous, and the filter cloth covering the plates and frames of the plate and frame filter press has a small gap between it and the plates and frames, making it difficult to separate the filter cake residue from the plates and frames due to the obstruction of the filter cloth. Summary of the Invention

Detailed Implementation To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this invention. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0015] In one embodiment, see Figure 1 The present invention provides a vibratory unloading device for a plate and frame filter press, comprising a support beam 1, a plate and frame 2, a moving component, and a vibrating component.

[0016] The frame 2 is provided with a frame 2 arm, which slides on the support beam 1. The moving component includes a guide rail 4 installed on both sides of the support beam 1 and a pull plate trolley 5 movably installed on the guide rail 4. The guide rail 4 is provided with a transmission component 6 connected to the pull plate trolley 5. Two sets of push plate arms 7 are spaced apart and movably installed on the pull plate trolley 5. A rebound spring 8 is provided between the push plate arms 7 and the pull plate trolley 5. Under the action of external force, the transmission component 6 drives the pull plate trolley 5 to move back and forth along the guide rail 4, so that the push plate arms 7 move back and forth and drive the frame 2 to move on the support beam 1. The vibrating component includes a lifting component 9 installed on the pull plate trolley 5 on one side of the support beam 1 and a vibrator 10 connected to the lifting component 9. The center of the lifting component 9 and the two sets of push plate arms 7 are located on the same plane. The width of the vibrator 10 is greater than the width of the frame 2 arm. Under the action of external force, the lifting component 9 drives the vibrator 10 to move back and forth up and down, thereby ejecting one end of the frame 2 upward and then swinging it down freely.

[0017] In this embodiment, see Figure 1Two sets of support beams 1 are spaced apart and parallel to each other. The two sets of support beams 1 are stably fixed on the ground. Multiple sets of plate frames 2 after filtration are mounted on the support beams 1. The middle part of the plate frame 2, that is, the part fitted with filter cloth 11, is located between the two sets of plate frames 2. The two sides of the plate frame 2 are connected to the plate frame 2 arms by bolts. The width of the plate frame 2 arms is less than the width of the plate frame 2. The plate frame 2 arms at both ends of the plate frame 2 are located at the top of the support beams 1 and the two ends extend beyond the sides of the support beams 1 respectively. Since the plate frame 2 has thickness, there is a gap between the plate frame 2 arms of the two adjacent sets of plate frames 2, so that the push plate arm 7 can abut against the plate frame 2 arms and push the plate frame 2 to move along the support beams 1.

[0018] In this embodiment, see Figure 1 , 2 The bottom of the pull plate trolley 5 is provided with a slide groove 12, and a roller that contacts the guide rail 4 is provided in the slide groove 12. The transmission component 6 includes a transmission chain 601 installed on the guide rail 4 and a transmission motor 602 connected to the transmission chain 601. The transmission chain 601 is connected to the pull plate trolley 5.

[0019] Preferably, two sets of support frames 13 are installed on both sides of the support beam 1, and the guide rail 4 is installed on the support frame 13. The slide groove 12 has a square structure and is located at the bottom of the pull plate trolley 5. The rollers are connected to the inner wall of the slide groove 12 through the rotating shaft and can be installed on the bottom and side surfaces of the slide groove 12. The relative position of the pull plate trolley 5 and the guide rail 4 is restricted by the connection between the slide groove 12 and the guide rail 4. In order to facilitate the installation of the pull plate trolley 5, a "U" shaped groove can be opened at the bottom of the pull plate trolley 5, and the rollers can be installed in the U-shaped groove. Then, the bottom plate 14 is connected to the bottom of the U-shaped groove by bolts. The rollers are also installed on the bottom plate. The bottom plate and the U-shaped groove form a directional structure. The rollers and the four sides of the guide rail 4 are in contact with the guide rail 4, thereby ensuring a stable connection between the pull plate trolley 5 and the guide rail 4.

[0020] Preferably, the output end of the drive motor 602 is equipped with a drive chain 601 wheel, which is connected to the drive chain 601. By rotating the drive motor 602 forward or in reverse, the drive chain 601 is driven to move back and forth along the guide rail 4, thereby driving the pull plate trolley 5 to move back and forth on the guide rail 4.

[0021] In this embodiment, see Figure 1 , 2 The pusher arm 7 includes an arc-shaped section 701 connected to the puller trolley 5 and an inclined arm section 702 connected to the arc-shaped section 701. The plane of the inclined arm section 702 is higher than the plane of the arc-shaped section 701, and the height of the inclined arm section 702 increases progressively.

[0022] Preferably, the pull plate trolley 5 is provided with two sets of connecting ears 15 spaced apart. A connecting shaft 16 is rotatably provided inside the connecting ears 15. A rebound spring 8 is installed between the connecting shaft 16 and the connecting ears 15. The arc-shaped segment 701 is fixedly connected to the connecting shaft 16. During the movement of the pull plate trolley 5 along the guide rail 4, the arc-shaped segment 701 first contacts the pull plate and causes one set of push plate arms 7 to flip downward under the pressure of the pull plate. When the pull plate is located between the two sets of push plate arms 7, the other set of push plate arms 7 is not subjected to force and remains in a normal state. At this time, the inclined arm segment 702 of the push plate arm 7 is higher than the bottom end of the plate frame 2 arm. During the movement of the pull plate trolley 5, the push plate arm 7 abuts against the plate frame 2 arm.

[0023] In this embodiment, see Figure 2 , 3 The lifting component 9 includes a telescopic rod 901 mounted on the pull plate trolley 5. There is a gap between the telescopic rod 901 and the push plate arm 7. The center of the telescopic rod 901 and the two sets of push plate arms 7 are located on the same plane.

[0024] Preferably, the telescopic pole 901 can be an electric telescopic pole 901, and a cable reel 17 is installed on the outside. The wire 18 connected to the electric telescopic pole 901 is located inside the cable reel 17. During the process of the transmission chain 601 driving the pull plate trolley 5 to move along the guide rail 4, the cable reel 17 simultaneously loosens or winds up the wire 18, so as to supply power to the electric telescopic pole 901 and prevent the wire 18 from being dragged on the ground.

[0025] In this embodiment, see Figure 2 , 3 The vibrator 10 includes a vibrating disc 1001 mounted on a telescopic rod 901 and a vibrating head 1002 mounted on the arm of the frame 2. The width of the vibrating disc 1001 is greater than the width of the vibrating head 1002.

[0026] Preferably, the vibrating disc 1001 is made of circular metal and has a rubber cushioning layer on it.

[0027] In this embodiment, see Figure 3The top of the vibrating disc 1001 is provided with a protrusion 19 with a decreasing outer diameter. After the telescopic rod 901 pushes the vibrating disc 1001 upward, the protrusion 19 abuts against the vibrating head 1002 and pushes the plate frame 2 upward, and then quickly disengages from the plate frame 2 arm, allowing the plate frame 2 to fall freely. Due to the decreasing outer diameter of the protrusion 19, the force acting on the plate frame 2 arm is not vertically upward. After the force pushes the plate frame 2 arm upward, the plate frame 2 shifts by a small distance, and the other end of the plate frame 2 does not move upward with it, but is only located on the support beam 1. Thus, when the end of the plate frame 2 that is lifted moves downward, it swings. As the telescopic rod 901 quickly lifts the plate frame 2 arm multiple times, the landing point of the entire plate frame 2 after one side falls is different, realizing the swinging fall of the plate frame 2. During the entire swinging fall of the plate frame 2, the filter cake residue attached to the plate frame 2 is shaken, causing the filter cake residue to separate from the plate frame 2.

[0028] In this embodiment, see Figure 2 The pull plate trolley 5 is also equipped with a limit rod 20, and a limit frame 21 is provided on the limit rod 20. The center of the limit frame 21 and the center of the two sets of pull plate arms are located on the same plane.

[0029] Preferably, the limiting rod 20 is welded or bolted to the side of the pull plate trolley 5 away from the plate frame 2. The limiting frame 21 has a U-shaped structure and is connected to the limiting rod 20 by bolts or welding. The bottom end of the limiting frame 21 is located above the top end of the plate frame 2 arm, and there is a gap between the two. During the process of the plate frame 2 arm being bounced up, the limiting frame 21 restricts the swing space of the plate frame 2 arm. Under the limitation of the limiting frame 21, the plate frame 2 arm is still within the range of the vibrating plate 1001 after falling, which makes it easy for the vibrating plate 1001 to push the plate frame 2 arm up again. Of course, the width of the vibrating plate 1001 can also be set to be greater than the internal width of the limiting frame 21 to ensure that the plate frame 2 arm is within the area of ​​the vibrating plate 1001 after falling.

[0030] In this embodiment, see Figure 1 , 2 It also includes a control system, which includes a controller 22 and two sets of contact switches 23 mounted on the pusher arm 7. The controller 22 is electrically connected to the contact switches 23, the drive motor 602, and the telescopic rod 901, respectively.

[0031] Preferably, the controller 22 adopts an existing PLC control system to control the rotation duration and time interval of the drive motor 602, and also to control the working frequency of the electric telescopic rod 901. The contact switch 23 is mounted on the pusher arm 7. As the drive motor 602 rotates, it drives the pusher arm 7 to move along the guide rail 4. After one set of pusher arms 7 is pressed down and abuts against the contact switch 23, another set of pusher arms 7 abuts against the arm of the plate frame 2. At this time, the signal from the contact switch 23 is transmitted to the controller 22, which controls the drive motor 602 to reverse, driving the pull-plate trolley 5 to move in the opposite direction along the guide rail 4. The pressed-down pusher arms 7 flip and abut against the arm of the plate frame 2, thereby driving the plate frame 2 to move along the support beam 1. The controller 22 controls the working duration of the drive motor 602, which controls the moving distance of the plate frame 2. After the plate frame 2 moves a certain distance, it pauses. The controller 22 controls the electric push rod to move up and down rapidly. The vibrating disc 1001 pushes the plate frame 2 arm to move up and fall freely. At this time, the plate frame 2 is displaced and shaken under the pushing and vibrating action of the vibrating disc 1001. The filter cake residue attached to the plate frame 2 is shaken off. After the plate frame 2 arm is pushed and vibrated several times, the controller 22 controls the drive motor 602 to reverse again, pushing the vibrated plate frame 2 a distance to the side of the vibrated plate frame 2. At this time, the push plate arm 7 on the side of the vibrated plate frame 2 is pressed down and flips. The contact switch 23 transmits the signal to the controller 22. The controller 22 controls the drive motor 602 to rotate forward, so that the plate pulling trolley 5 moves toward the plate frame 2 to be vibrated and deslag removed, and pulls the new plate frame 2 to be deslag removed, and starts to repeat the above frame moving and vibrating process, vibrating and deslag removing the plate frame 2 one by one.

[0032] In this embodiment, the controller 22 controls the drive motor 602 to rotate, thereby causing the drive chain 601 to move the plate-pulling trolley 5 along the guide rail 4 to the plate frame 2 to be descaled. The push plate arm 7 on the side near the descaled area is pressed down and flipped, pressing down the contact switch 23. The push plate arm 7 on the other side abuts against the arm of the plate frame 2 to be descaled. At this time, the controller 22 controls the drive motor 602 to reverse, causing the plate-pulling trolley 5 to move away from the plate frame 2 to be descaled. After moving the plate frame 2 to be descaled along the support beam 1 for a certain distance, the drive motor 602 is stopped, and the controller 22 controls the telescopic rod 901 to quickly extend and retract multiple times from the plate frame 2 to the plate frame 2 to be descaled. One side of the plate frame 2 is ejected from the supporting beam 1, causing one side of the plate frame 2 to swing and fall freely. During this process, the plate frame 2 vibrates and swings, causing the filter cake residue attached to the plate frame 2 to separate from the plate frame 2. After the vibration is completed, the controller 22 controls the drive motor 602 to rotate again, driving the plate frame 2 away from the plate frame 2 to be descaled, and moving the descaled plate frame 2 to the other side of the supporting beam 1. Then the controller 22 controls the drive motor 602 to reverse, causing the plate pulling trolley 5 to move toward the plate frame 2 to be descaled, and repeating the above frame moving and vibration process, vibrating and descaling the plate frame 2 one by one.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
