Description

Technical Field

[0001] This application relates to the field of filter press slag discharge technology, and in particular to a vibrating trolley for a filter press. Background Technology

[0002] In industrial production, chamber filter presses are commonly used solid-liquid separation equipment and are widely used in many fields such as chemical, pharmaceutical, food, and environmental protection. With its advantages of simple structure, convenient operation and large filtration area, it can effectively separate solid particles from liquid in suspension, thereby obtaining relatively pure filtrate and solid filter cake.

[0003] The hydraulic mechanism of the chamber filter press can squeeze multiple filter plates to form a sealed filter chamber between adjacent filter plates. The slurry supply valve is used to deliver the suspension to be treated into the filter chamber. When the suspension enters the filter chamber, under pressure, the liquid passes through the filter cloth and is discharged from the liquid outlet under the filter plate, while the solid particles are trapped in the filter chamber and gradually form a filter cake.

[0004] After solid-liquid separation, the filter press plates are pushed to separate the filter cake inside. However, in actual production, due to the strong pressure inside the filter chamber caused by the hydraulic mechanism, some filter cake adheres too tightly to the filter cloth and the filter press plates. Even though most of the filter cake falls off smoothly after the filter press plates separate, some filter cake and filter cake fragments remain inside the plates. In practice, the cleaning of residual filter cake and debris inside the filter press plates mainly relies on manual operation. The filter plates are tapped to vibrate and the filter cake inside falls off, thus completing the cleaning. However, this method is inefficient and has high labor costs, which affects the working efficiency of the chamber filter press.

[0005] To address the aforementioned issues, a vibrating trolley for a filter press is now designed. Utility Model Content

A slurry supply valve is provided at the other end of the machine body. A push plate mechanism for separating the filter plates is provided on the crossbeam.

The machine body is equipped with a rapping mechanism, which is used to tap the filter plate to remove filter residue; The rapping mechanism includes a drive unit arranged on the machine body and a striking unit arranged on the drive unit.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This application provides a vibrating trolley for a filter press, which can solve the problem in related technologies that after solid-liquid separation, some filter cake and filter cake fragments still remain inside the filter press plate, making manual cleaning inconvenient.

[0019] Please see Figures 1-3 A vibrating trolley for a filter press includes: a body 1 with two opposing crossbeams 2, on which a head plate 3, multiple filter plates 4, and a pressing plate 5 are arranged sequentially along the length of the body 1; handles 41 are provided on both sides of each filter plate 4; a hydraulic mechanism 6 is provided at one end of the body 1 for pushing the pressing plate 5 to squeeze the multiple filter plates 4; a slurry supply valve 7 is provided at the other end of the body 1; and a pusher mechanism 8 for separating the filter plates 4 is provided on the crossbeams 2, which includes a drive mechanism located at the bottom of the crossbeams 2. The machine body 1 is provided with a vibration mechanism 9, which is used to knock the filter plate 4 to remove filter residue. The vibration mechanism 9 includes a driving part 91 arranged on the machine body 1 and a striking part 92 arranged on the driving part 91. The driving part 91 is used to drive the striking part 92 to move along the length of the machine body 1, and the striking part 92 is used to knock the filter plate 4.

[0020] The driving component 81 controls the pushing component 82 to move to the appropriate position of the corresponding filter plate 4. The pushing component 82 contacts the handle 41 of the filter plate 4. Then, the driving component 81 controls the pushing component 82 to move again, and the pushing component 82 drives the corresponding filter plate 4 to move together. In this way, the separation operation of multiple filter plates 4 is performed in sequence.

[0021] After the filter press plate 4 is separated, the drive unit 91 starts and controls the striking unit 92 to move along the length of the machine body 1. The striking unit 92 can reach the front of the filter press plate 4 at different positions in sequence and strike it. The vibration generated by the striking causes the filter residue attached to the filter press plate 4 to fall off, thereby achieving the purpose of removing the filter residue and ensuring the normal operation and filtration effect of the filter press.

[0022] By using the drive unit 91 and the striking unit 92 in conjunction, the device can move to the position of the filter press plate 4 that needs to be struck and strike it. The vibration generated by the striking causes the filter residue attached to the filter press plate 4 to fall off. Compared with manual operation, this greatly improves the accuracy and effectiveness of the rapping cleaning and increases the cleaning efficiency.

[0023] like Figure 4 and Figure 5 As shown, in one embodiment, the drive unit 91 includes a mounting bracket 911 arranged on the body 1. Two mounting plates 912 are arranged opposite each other on the mounting bracket 911. A lead screw 913 is rotatably arranged between the two mounting plates 912. A transmission block 914 is threadedly connected to the lead screw 913. Two support plates 915 located opposite each other on both sides of the lead screw 913 are arranged on the mounting bracket 911. A movable seat 916, L-shaped, is slidably connected between the outer sides of the two support plates 915. The transmission block 914 is connected to the movable seat 916. A drive motor 917 and a reducer 918 are arranged on the mounting bracket 911. The output shaft of the drive motor 917 is connected to the input shaft of the reducer 918. The output shaft of the reducer 918 is connected to either end of the lead screw 913. A threaded hole adapted to the lead screw 913 is provided on the transmission block 914. After the drive motor 917 starts, its output shaft begins to rotate, transmitting power to the input shaft of the reducer 918 connected to it. The reducer 918 reduces the speed and increases the torque of the high-speed rotation output by the drive motor 917, and then transmits the processed power to one end of the lead screw 913 through its output shaft, so that the lead screw 913 obtains rotational power and begins to rotate around its own axis.

[0024] When the lead screw 913 rotates, the transmission block 914 is threadedly connected to the lead screw 913, and the transmission block 914 cannot rotate with the lead screw 913 due to the restriction of the moving seat 916 and the support plate 915. According to the principle of threaded transmission, the transmission block 914 will move linearly along the axis of the lead screw 913. The transmission block 914 is connected to the moving seat 916, and the moving seat 916 will slide linearly along the length of the support plate 915 together with the transmission block 914.

[0025] The movable seat 916 is connected to the striking part 92. As the movable seat 916 slides linearly, the striking part 92 also moves along the length of the machine body 1, thereby striking the filter plates 4 at different positions in sequence to remove filter residue.

[0026] like Figure 4 and Figure 5As shown, specifically, the striking part 92 in this embodiment includes a fixed frame 921 mounted on a movable seat 916. A cylinder 922 is mounted on the fixed frame 921. A fixed plate 923 is mounted on the piston rod of the cylinder 922. A plurality of transmission rods 924 are mounted on the other end of the fixed plate 923. A connector 925 is mounted on the other end of the transmission rod 924. A striking plate 926 is mounted between two adjacent connectors 925.

[0027] When the striking part 92 reaches the designated position, the cylinder 922 is activated, and the piston rod of the cylinder 922 begins to extend and retract. The fixed plate 923 moves back and forth with the extension and retraction of the piston rod. Specifically, when the piston rod of the cylinder 922 extends, it pushes the fixed plate 923 forward, thereby causing the striking plate 926 to move forward and impact the filter press plate 4. When the piston rod of the cylinder 922 retracts, it pulls the fixed plate 923 backward, causing the striking plate 926 to move away from the filter press plate 4, completing one striking action. Through the repeated extension and retraction of the piston rod of the cylinder 922, multiple strikes are achieved on the filter press plate 4.

[0028] Cylinder 922 can provide a large output force. By controlling the air pressure of cylinder 922, the extension and speed of the piston rod can be easily adjusted, thereby achieving the adjustment of the striking force.

[0029] Furthermore, the movement of cylinder 922 is controlled by a pneumatic control system, and the extension and retraction frequency of its piston rod can remain relatively stable. As a mature pneumatic component, cylinder 922 possesses high reliability and stability. Under normal operating conditions, cylinder 922 can operate continuously for extended periods without easily malfunctioning; this is existing technology and will not be elaborated upon further.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the hydraulic mechanism 6 includes a cylinder 61 mounted on the machine body 1 and a hydraulic power station 62 mounted on one side of the machine body 1. The piston rod of the cylinder 61 contacts the pressure plate 5, and the hydraulic power station 62 and the cylinder 61 are connected by an oil pipe.

[0031] The hydraulic power station 62 starts working. Its internal hydraulic pump draws hydraulic oil from the oil tank, pressurizes the hydraulic oil, and delivers it to the oil cylinder 61 through the oil pipe. At this time, the piston in the oil cylinder 61 is in the initial position under the action of the hydraulic oil, and the clamping plate 5 is in the loose state, preparing for the subsequent filter press operation.

[0032] Upon receiving the clamping command, the hydraulic power station 62 continues to supply high-pressure hydraulic oil to the cylinder 61. As the hydraulic oil continuously enters, the pressure inside the cylinder 61 gradually increases. Under the pressure, the piston begins to move, pushing the clamping plate 5 in contact with it towards the filter plate assembly. During its movement, the clamping plate 5 gradually presses the filter plates together, forming a tight seal. When the clamping force reaches the set value, the pressure sensor inside the hydraulic power station 62 detects the pressure signal and feeds it back to the control system. The control system then controls the hydraulic pump to stop operating or maintain a certain pressure output, keeping the clamping plate 5 in a clamped state. The hydraulic power station 62 maintains the pressure inside the cylinder 61 within the set value range by adjusting the flow rate and pressure of the hydraulic oil.

[0033] When the filter pressing process is completed, the equipment receives a release command. The hydraulic power station 62 changes the direction of hydraulic oil delivery, causing the hydraulic oil in the cylinder 61 to flow back to the oil tank. As the hydraulic oil flows back, the pressure in the cylinder 61 gradually decreases. Under the action of spring force or external load, the piston begins to return, driving the pressing plate 5 away from the filter plate assembly, thus releasing the filter plates.

[0034] In actual operation, the operator can directly control the start and stop of the hydraulic pump and the direction of hydraulic oil delivery through the manual control buttons on the hydraulic power station 62, thereby realizing the manual operation of the cylinder 61. Alternatively, parameters such as clamping force and holding time can be set on the control panel, and the control system will automatically control the operation of the hydraulic power station 62 according to the preset program. This is existing technology and will not be described in detail here.

[0035] like Figure 3 and Figure 6 As shown, in one embodiment, the driving component 81 includes a housing 811 disposed below the crossbeam 2. The crossbeam 2 has a through hole 21 and communicates with the housing 811. A second driving motor 812 is disposed inside the housing 811. A second lead screw 813 is disposed on the output shaft of the second driving motor 812. A second transmission block 814 is disposed on the outer side of the second lead screw 813.

[0036] After the start command is issued, the second drive motor 812 starts to run, the output shaft of the second drive motor 812 starts to rotate, and the second lead screw 813 will rotate synchronously with the output shaft. The second transmission block 814 is provided with a threaded hole that matches the second lead screw 813.

[0037] When the lead screw 2 813 rotates, according to the principle of lead screw transmission, the transmission block 2 814 will convert the rotational motion of the lead screw 2 813 into its own linear motion. The transmission block 2 814 moves linearly along the axis of the lead screw 2 813, and its direction of movement depends on the rotation direction of the lead screw 2 813. When the drive motor 2 812 rotates forward, the transmission block 2 814 may move along the lead screw 2 813 in one direction; when the drive motor 2 812 rotates in reverse, the transmission block 2 814 will move in the opposite direction.

[0038] like Figure 3 and Figure 6 As shown, in one embodiment, the pusher 82 includes an electric push rod 821 arranged in the through hole 21. The bottom of the electric push rod 821 is connected to the transmission block 814. The piston rod of the electric push rod 821 is provided with a lever 822. The electric push rod 821 is used to drive the lever 822 to move up and down.

[0039] When the device is in the initial position, the electric push rod 821 is in the retracted state, the lever 822 is in the lower position, the transmission block 814 is also in the initial position of its stroke, and the entire pusher 82 is in a relatively stationary state and has not performed a push operation.

[0040] When the device receives the start signal, the drive unit 81 starts to work. Since the bottom of the electric push rod 821 is connected to the transmission block 814, the electric push rod 821 will move together with the transmission block 814 to reach the predetermined position.

[0041] When the electric actuator 821 moves to the designated horizontal position, the electric actuator 821 sends an extension command, and the electric actuator 821 pushes the piston rod to extend outward, and the lever 822 also rises accordingly to reach the preset height position.

[0042] After the lever 822 rises to the specified height, it will contact the handle 41 that needs to push the filter plate 4. Then, the drive unit 81 will work again, driving the lever 822 to move away from the filter plate 4. At the same time, the lever 822 will contact the handle of the filter plate 4, thereby causing the filter plate 4 to separate.

[0043] After the pushing operation is completed, the electric push rod 821 retracts the piston rod, causing the lever 822 to descend back to its initial lower position. Then, the drive unit 81 starts again, and the drive motor 812 drives the lead screw 813 to rotate. The transmission block 814 moves along the lead screw 813 to a suitable position below the next filter plate 4 that needs to be separated. The electric push rod 821 also moves to that position, waiting for the next separation operation.
