[0036] After the traditional filter press is completed, a filter cake will be formed. It is usually necessary to pull the filter plates or filter cloths apart piece by piece to remove the filter cake in the filter chamber, which results in low efficiency in removing the filter cake. During the filtration process, due to the direct contact between the filter cake and the filter cloth, adhesion will form between the filter cake and the filter cloth or filter plate. In addition, during the high-pressure filtration process, the formation of the filter cake will also increase the cohesive force of the filter cake, making it difficult to peel off the filter cake.

[0037] In view of this, the embodiment of the present application provides a filter bag vibration unloading device on the filter press. The vibration mechanism moves to the corresponding position of the filter bag when the filter bag is unloading, and vibrates the suspension device on the top of the filter bag. The vibration force is transmitted to the filter bag, which effectively destroys the adhesion between the filter cake and the filter bag, making the filter cake easier to fall from the opening, thereby improving the unloading efficiency, reducing the intensity and difficulty of manual operation, and enhancing the uniformity and integrity of the unloading process.

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Figure 1 This is a schematic diagram of the structure of the filter bag vibration unloading device provided in the embodiment of the present application. Figure 2 A bottom view of the filter bag vibrating unloading device provided in an embodiment of the present application, Figure 3 A schematic diagram of the structure of the vibrating member of the filter bag vibrating unloading device provided in an embodiment of the present application, Figure 4 This is a schematic diagram of the structure of the connecting member of the filter bag vibration unloading device provided in the embodiment of the present application, Figure 5 A schematic diagram of the connecting parts and protective structure of the filter bag vibration unloading device provided in an embodiment of the present application.

[0040] The embodiment of the present application provides a filter press, including a frame 100, a filter bag assembly 200 and a filter bag vibration unloading device arranged on the frame 100, the filter bag assembly 200 is movably arranged on the frame 100, and the filter bag vibration unloading device is arranged on the frame 100. The filter bag vibration unloading device is used to generate vibration force, perform high-frequency vibration on the filter bag assembly 200, and shake out the filter cake that cannot fall by its own weight after the filter pressure in the filter bag assembly 200 is completed, out of the filter bag 202.

[0041] For example, Figure 1 and Figure 2 As shown, the sealing device 204 is used to seal the bottom opening of the filter bag 202 when the filter bag 202 is feeding or filtering, and the sealing device 204 is also used to open the filter bag 202 after filtering. The pressing plate 201 is used to squeeze the filter bag 202 so that the filtered material in the filter bag 202 forms a filter cake after filtering. The filter bag 202 is suspended on the frame 100 by the suspension device 203 to ensure that the filter bag 202 can maintain a stable suspension posture during the filtering process to prevent shaking or deviation from affecting the filtering effect.

[0042] In some embodiments of the present application, the filter bag vibration unloading device includes a filter bag assembly 200 and at least one vibration mechanism 401. The filter bag assembly 200 includes a suspension device 203 and a filter bag 202, the suspension device 203 is connected to the top of the filter bag 202, and the bottom of the filter bag 202 has an opening. The vibration mechanism 401 is movably arranged, and the vibration mechanism 401 is configured to move to the corresponding filter bag 202 and vibrate the suspension device 203 when the filter bag 202 is unloaded, so that the filter cake in the filter bag 202 falls from the opening.

[0043] In the embodiment of the present application, two vibration mechanisms 401 are provided, which are respectively arranged at the two ends of the filter bag assembly 200. It should be noted that the vibration mechanisms 401 can be but are not limited to two, for example, they can also be arranged on one side of the filter bag assembly 200. It can be understood that when two vibration mechanisms 401 are provided, the filter cake can achieve more balanced and effective vibration during the unloading process, thereby enhancing the effect of the filter cake falling off from the filter bag 202.

[0044] The filter bag assembly 200 includes a suspension device 203 and a filter bag 202. The filter bag 202 is suspended on the frame 100 through the suspension device 203, and the filter bag 202 can be moved and arranged on the frame 100 through the suspension device 203. In the embodiment of the present application, the number of the filter bags 202 is set to twelve. It should be noted that the number of the filter bags 202 can be twelve, but is not limited to twelve, and can be any number, and there is a filter plate between two adjacent filter bags 202. The bottom of each filter bag 202 is provided with an opening, and the opening is connected to the sealing device 204. The sealing device 204 can control the opening of the filter bag 202 to be closed or open. When the filter bag 202 is in feeding or pressure filtering, the opening is closed, and when the filter bag 202 is in the pressure filtering, the opening is open.

[0045] It is understood that when the filter bag 202 is in the process of feeding or filtering, the sealing device 204 closes the opening at the bottom of the filter bag 202 to ensure that the filter material is injected into the filter bag 202, and the pressure plate 201 is controlled to squeeze the filter bag 202, and the liquid is separated so that the filter material in the filter bag 202 forms a filter cake, and then the sealing device 204 opens the opening at the bottom of the filter bag 202. After the filtering is completed, the filter cake in part of the filter bag 202 can fall naturally from the opening at the bottom of the filter bag 202 by its own weight. If the filter cake in the filter bag 202 is stuck to the filter bag 202 and cannot fall by its own weight, it can fall from the opening of the filter bag 202 under the action of the vibration of the vibration unloading device and the weight of the filter cake itself, thereby separating the filter cake from the filter bag 202. By arranging the vibration of the vibration unloading device on the filter press, it is also beneficial to improve the unloading efficiency of the filter cake, and under the action of the up and down vibration, the filter cake in the filter bag 202 can fall off from the filter bag 202 more evenly.

[0046] It should be noted that the filter bag 202 in the filter bag assembly 200 can be connected to the suspension device 203 via a sensor (not shown in the figure), and the weight of the filter bag 202 can be identified by the sensor to determine whether the filter cake in the filter bag 202 can be discharged by its own weight after the filtration is completed. If the filter cake in the filter bag 202 is adhered to the filter bag 202 and cannot be discharged by its own weight, the filter press can control the filter bag vibration discharge device to move to the corresponding filter bag 202 to vibrate up and down to complete the discharge.

[0047] In some embodiments of the present application, each vibration mechanism 401 includes a vibration member 402 and a conveying device 403, and the vibration member 402 is disposed on the conveying device 403, so that the conveying device 403 drives the vibration member 402 to move. The top end of the vibration member 402 abuts against one end of the suspension device 203, and the suspension device 203 is vibrated by the vibration member 402, so that the filter cake in the filter bag 202 falls from the opening.

[0048] like Figure 1 and Figure 2 As shown, each vibration mechanism 401 includes a vibration member 402 and a conveying device 403. The vibration member 402 can be installed on the conveying device 403. The conveying device 403 drives the movement of the vibration member 402, so that the vibration member 402 reaches the specific unloading position of the filter bag 202, and then carries out the subsequent vibration operation. The top of the vibration member 402 abuts against the suspension device 203 in the filter bag assembly 200, and the vibration member 402 generates an up-and-down vibration force, which is transmitted to the filter bag 202 through the suspension device 203. The filter bag 202 generates up-and-down high-frequency vibration, destroys the adhesion between the filter cake and the filter bag 202, and makes the filter cake fall smoothly from the open end of the filter bag 202 under the gravity of the filter cake itself.

[0049] It is understandable that the vibrating member 402 is moved on the frame 100 to the lower side of the suspension device 203 in the corresponding filter bag assembly 200 by the conveying device 403. Therefore, the moving position and moving path of the vibrating member 402 can be accurately controlled, thereby achieving accurate unloading for different filter bags 202.

[0050] It should be noted that the vibrating member 402 can be a vibration exciter, a vibration motor, or a motor with a piston cylinder. The vibration exciter and the vibration motor are existing devices, and the specific working principle and structure can refer to the existing devices. In the embodiment of the present application, a motor with a piston cylinder is specifically taken as an example.

[0051] In some embodiments of the present application, each vibration mechanism 401 further includes a top plate 4011, a first fixing member 4013 and at least one top rod 4012, one end of each top rod 4012 is connected to the top plate 4011, part of the top rod 4012 is inserted into the first fixing member 4013, and a motor and a piston cylinder may be provided inside the first fixing member 4013. The top plate 4011 is in contact with the filter bag assembly 200, and the top rod 4012 is driven by the motor inside the first fixing member 4013 to realize the vibration of the top plate 4011 suspension device 203, so that the filter cake in the filter bag 202 falls from the opening.

[0052] like Figure 3As shown, in the embodiment of the present application, each vibration mechanism 401 includes a top plate 4011 and two top rods 4012 connected to the top plate 4011. It should be noted that the number of top rods 4012 can be one or two, and setting two top rods 4012 connected to the top plate 4011 can enhance stability, provide more stable support for the top plate 4011, and transmit up and down vibration force.

[0053] It is understood that one end of the top rod 4012 is connected to the top plate 4011, and part of the top rod 4012 is inserted into the first fixing member 4013. A motor (not shown in the figure) may be provided inside the first fixing member 4013, and the motor drives the top rod 4012 to perform piston motion, thereby providing an up-and-down vibration force to be transmitted to the top plate 4011. The other end of the top plate 4011 abuts against the suspension device 203 in the filter bag assembly 200, so that the vibration generated by the vibration member 402 can be effectively transmitted to the filter bag 202 connected to the suspension device 203. During the vibration process, the top plate 4011 can ensure the stability of the movement trajectory of the top rod 4012 and the vibration member 402, avoid the deviation caused by vibration, and help to ensure that the vibration mechanism 401 acts accurately on the filter bag assembly 200, so that the filter cake that cannot fall from the open mouth of the filter bag 202 by its own weight after the filter pressing is completed falls under the action of the vibration force. Furthermore, by appropriately adjusting parameters such as the length of the top rod 4012 , the vibration effect of the vibration mechanism 401 on the filter bag assembly 200 can be fine-tuned to meet the unloading requirements of different filter bags 202 .

[0054] In another possible implementation, the vibrating member 402 may further include a connecting member 4014, the connecting member 4014 is connected to the first fixing member 4013, and the vibrating member 402 is disposed on the conveying device 403 through the connecting member 4014. The conveying device 403 may further include a protective structure 4038, the protective structure 4038 is sleeved on a part of the transmission element 4033, and the vibrating member 402 is disposed on the protective structure 4038 through the connecting member 4014.

[0055] Combination Figure 3 and Figure 4 As shown, the connecting member 4014 is composed of an L member 4015 and a T member 4016, and the bottom end of the T member 4016 is connected to the top end of the first fixing member 4013. Both ends of the transmission element 4033 can be sleeved on the T member 4016, so that the vibrating member 402 is connected to the transmission element 4033 through the connecting member 4014. It can be understood that the transmission element 4033 can be a belt.

[0056] like Figure 5As shown, the protective structure 4038 is sleeved on the transmission element 4033 to prevent debris or foreign matter from entering the conveying device 403, and the protective structure 4038 can also buffer the external impact and vibration of the conveying device 403 during operation. In the embodiment of the present application, two protective structures 4038 are provided, and a groove 4039 is also provided on the top protective structure 4038. The T piece 4016 on the connecting piece 4014 can pass through the groove 4039, so that part of the connecting piece 4014 can be sleeved on the protective structure 4038, and the vibrating piece 402 can move on the protective structure 4038.

[0057] In some embodiments of the present application, each vibration mechanism 401 further includes a motor, which is connected to the conveying device 403. The motor drives the conveying device 403 to drive the vibration member 402 to move to the corresponding filter bag 202. In the embodiment of the present application, each vibration mechanism 401 includes a motor (not shown in the figure), which can be connected to the conveying device 403 as a power source, and the conveying device 403 can be driven by the motor to move, so that the vibration member 402 on the conveying device 403 can be moved to the lower part of the suspension device 203 of the corresponding filter bag assembly 200, thereby reducing the complexity of manual operation and improving the efficiency and accuracy of unloading.

[0058] In some embodiments of the present application, the conveying device 403 further includes a first rotating wheel 4031 and a second rotating wheel 4032. The first rotating wheel 4031 is connected to a motor, and the first rotating wheel 4031 is driven to move by the motor. In a possible implementation, the motor can be connected to the first rotating wheel 4031, and the motor drives the conveying device 403 by driving the first rotating wheel 4031 to rotate, so that the vibrating member 402 on the conveying device 403 can move to the lower side of the corresponding suspension device 203 of the filter bag assembly 200. The conveying device 403 can accurately control the movement trajectory and speed of the vibrating member 402 through the motor, thereby ensuring that the vibrating member 402 can accurately move to the corresponding filter bag 202 position and perform up and down vibration unloading.

[0059] In some embodiments of the present application, Figure 1 and Figure 2As shown, the transmission device 403 also includes a transmission element 4033, which is arranged on the first rotating wheel 4031 and the second rotating wheel 4032, and the vibrating member 402 is arranged on the transmission element 4033, and the first rotating wheel 4031 is driven by the motor to move so that the vibrating member 402 on the transmission element 4033 moves to the corresponding filter bag 202. The transmission element 4033 can bear and transmit power to ensure the stable movement of the vibrating member 402 on the transmission element 4033. In addition, the vibrating member 402 and the transmission element 4033 are detachably connected, which can be easily disassembled and replaced, thereby reducing the maintenance cost of the equipment and improving the maintenance efficiency. It should be noted that the transmission element 4033 can be a chain or a belt, etc.

[0060] That is to say, the motor can be connected to the first rotating wheel 4031, and the motor can drive the first rotating wheel 4031 to move, thereby prompting the vibrating member 402 on the transmission element 4033 connected to the first rotating wheel 4031 to move to the position below the suspension device 203 of the corresponding filter bag assembly 200, and carry out subsequent up and down vibration unloading.

[0061] In some embodiments of the present application, the conveying device 403 further includes a second fixing member 4034 and a first rotating shaft 4036 . The second fixing member 4034 is connected to the first rotating wheel 4031 via the first rotating shaft 4036 , and a plurality of fixing holes 4035 are provided on the second fixing member 4034 .

[0062] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the motor can be connected to the first rotating wheel 4031 through the first rotating shaft 4036, and the motor can be stably fixed on the frame 100 by using the second fixing member 4034. The motor drives the first rotating shaft 4036 to move, so that the first rotating wheel 4031 can rotate smoothly on the first rotating shaft 4036, so as to realize the movement of the vibrating member 402 on the transmission element 4033 connected to the first rotating wheel 4031. In a possible implementation, four fixing holes 4035 can be provided on the second fixing member 4034, and the motor can be connected to the frame 100 through the second fixing member 4034. It should be noted that the second fixing member 4034 and the motor can be fixed to the frame 100 by fasteners passing through the fixing holes 4035.

[0063] In some embodiments of the present application, a second rotating shaft 4037 is further included, and the second rotating wheels 4032 in two adjacent vibration mechanisms 401 are connected via the second rotating shaft 4037. Figure 1 and Figure 2In the embodiment of the present application, two vibration mechanisms 401 are provided, and the two second rotating wheels 4032 in the two vibration mechanisms 401 are connected via a second rotating shaft 4037. It can be understood that by connecting the two second rotating wheels 4032 in the two vibration mechanisms 401 via the second rotating shaft 4037, the vibration members 402 in the two vibration mechanisms 401 can be moved synchronously, ensuring that the two vibration members 402 can accurately move to the two ends of the corresponding suspension device 203 of the filter bag assembly 200, providing coordinated up and down vibration to the filter bag 202, ensuring that the filter cake in the filter bag 202 can fall off.
