Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically a filter press with rapid vibration unloading. Background Technology

[0002] A filter press is a mechanical device that separates solid particles from liquid in a suspension by applying external pressure. It mainly consists of filter plates, filter frames, and filter chambers. It is an intermittent filtration device widely used in industries such as chemical, ceramics, and food. During operation, the material is pressed and dewatered to obtain sludge cakes and liquid. The resulting sludge cakes tend to adhere to the filter cloth, making separation difficult. Traditional solutions require manual peeling or cake scraping, which is not only inefficient and labor-intensive but also prone to damaging the filter cloth. To better clean the sludge cakes, a filter press with rapid vibration discharge is proposed.

[0003] As disclosed in the authorization announcement number CN222489043U, a filter press vibrating unloading mechanism includes a guide rail located on one side of the main beam of the filter press. A pull plate trolley is provided on the guide rail. The pull plate trolley includes a frame. The frame is provided with a vibrating assembly, a clamping assembly, and a limiting assembly. The vibrating assembly includes two telescopic cylinders arranged side by side on the frame along the direction of the guide rail. The cylinder rods of the telescopic cylinders extend upward. Vibrating seats are connected to the ends of the two cylinders. The vibrating seats include a top plate. Two support legs are integrally connected to the bottom of the top plate. The two support legs are configured to cooperate with the two cylinder rods. Each support leg has a stepped hole that penetrates the top plate. The vibrating seat is fixed to the cylinder rods by screws through the stepped holes.

[0004] Although it effectively solves the problems of the top pin being prone to breakage due to uncertain force direction and the drag chain being prone to breakage due to excessive drooping and bending in the existing technology, it greatly improves the reliability of the filter press operation;

[0005] However, this does not solve the problem that existing filter presses are not conducive to the reciprocating vibration and tapping of the filter plates to separate the sludge cake from the filter plates, nor to the sequential moving and vibrating cleaning of multiple filter plates and the scraping and cleaning of sludge, thus affecting the convenience of filter plate vibration cleaning and the efficiency of sludge cleaning. Utility Model Content

[0006] The purpose of this invention is to provide a filter press with rapid vibration unloading, in order to solve the problems mentioned in the background art, such as the filter press being inconvenient to reciprocate the vibration and knocking of the filter plates to separate the sludge cake from the filter plates, which is not conducive to the sequential moving and vibration cleaning of multiple filter plates and the scraping and cleaning of sludge, thus affecting the convenience of filter plate vibration cleaning and the efficiency of sludge cleaning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter press with rapid vibration unloading, comprising a frame and a material box. The material box is provided at the top of the frame, and multiple sets of filter plates are provided above the material box. A first integrated frame is symmetrically arranged on the outer wall of the material box. A first lead screw is movably installed inside each of the first integrated frames. A second stepper motor is provided on the side wall of each of the first integrated frames, and the output end of the second stepper motor is connected to the first lead screw. A first threaded sleeve is fitted on the surface of each of the first lead screws, and the first threaded sleeve is threadedly connected to the first lead screw. An integrated plate is provided at the top of each of the first threaded sleeves. A servo motor is provided on one side of each of the integrated plates. A drive shaft is installed at the output end of each of the servo motors. A short connecting arm is fitted on the surface of each of the drive shafts. A long connecting arm is provided at the end of each short connecting arm away from the drive shaft. A hinge shaft is provided at the end of each long connecting arm near the short connecting arm, and the long connecting arm is movably connected to the short connecting arm through the hinge shaft.

[0008] Preferably, each of the long connecting arms is provided with a reciprocating rod at the end away from the short connecting arm, and each of the reciprocating rods is provided with a linkage shaft at the end near the long connecting arm, and the reciprocating rod is movably connected to the long connecting arm through the linkage shaft.

[0009] Preferably, a limit block is provided on the other side of the integrated plate, and the reciprocating rod is slidably connected to the limit block.

[0010] Preferably, a second integrated frame is symmetrically installed on the inner wall of the material box, and a second lead screw is movably installed inside each of the second integrated frames.

[0011] Preferably, a first stepper motor is provided on the outer wall of the material box on one side of the second integrated frame, and the output end of the first stepper motor is connected to the second lead screw.

[0012] Preferably, the surface of the second lead screw is fitted with a second threaded sleeve, and the second threaded sleeve is threadedly connected to the second lead screw.

[0013] Preferably, a scraper is slidably disposed inside the material box, and the scraper is connected to the second threaded sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the filter press not only realizes the reciprocating vibration and knocking of the filter plate to separate the sludge cake from the filter plate, which facilitates the sequential moving and vibration cleaning of multiple filter plates and the scraping and cleaning of sludge, but also improves the convenience of filter plate vibration cleaning and the efficiency of sludge cleaning.

[0015] (1) After the filter press finishes its filtration work, sludge cakes will adhere to the surface of the filter plates. When it is necessary to clean the sludge cakes, the second stepper motor drives the first lead screw to rotate, the first lead screw drives the integrated plate to move through the first threaded sleeve, the integrated plate drives the reciprocating rod to move to the lower ends of both sides of the filter plate, the servo motor drives the drive shaft to rotate, the drive shaft drives the short connecting arm to rotate, the short connecting arm drives the long connecting arm to swing back and forth through the hinge shaft, and the long connecting arm drives the reciprocating rod to swing back and forth through the linkage shaft. The reciprocating rod slides back and forth inside the limiting block, and the reciprocating rod vibrates and knocks the filter plate to remove the sludge cake adhering to the surface of the filter plate. At the same time, under the continuous action of the second stepper motor, the integrated plate is driven to move continuously, thereby moving and vibrating multiple sets of filter plates in sequence to clean them. This achieves the effect of reciprocating vibration and knocking the filter plates to detach the sludge cake from the filter plates, making it convenient to move and vibrate multiple sets of filter plates in sequence to clean them, and improving the convenience of filter plate vibration and cleaning.

[0016] (2) After the sludge cake is broken up by vibration, it will fall into the inside of the material box. In order to clean it better, the first step motor drives the second lead screw to rotate, the second lead screw drives the second threaded sleeve to move, the second threaded sleeve drives the scraper to move, and the scraper scrapes the sludge inside the material box. After the sludge is scraped into a pile, it can be cleaned quickly to improve the efficiency of sludge cleaning. Attached Figure Description

[0026] Example 1

[0027] Please see Figure 1-5This utility model provides an embodiment of a rapid vibration unloading filter press, comprising a frame 1 and a material box 2. The material box 2 is located at the top of the frame 1, and multiple sets of filter plates 4 are arranged above the material box 2. A first integrated frame 3 is symmetrically arranged on the outer wall of the material box 2. A first lead screw 7 is movably installed inside each of the first integrated frame 3. A second stepper motor 9 is arranged on the side wall of each of the first integrated frame 3, serving as a power drive. The output end of the second stepper motor 9 is connected to the first lead screw 7. The surface of the first lead screw 7 is fitted with a first threaded sleeve 6, and the first threaded sleeve 6 is threadedly connected to the first lead screw 7. The top of the first threaded sleeve 6 is provided with an integrated plate 5, and a servo motor 10 is provided on one side of the integrated plate 5. The output end of the servo motor 10 is equipped with a drive shaft 11. The surface of the drive shaft 11 is fitted with a short connecting arm 12. The end of the short connecting arm 12 away from the drive shaft 11 is provided with a long connecting arm 14. The end of the long connecting arm 14 close to the short connecting arm 12 is provided with a hinge shaft 13, and the long connecting arm 14 is movably connected to the short connecting arm 12 through the hinge shaft 13.

[0028] A reciprocating rod 16 is provided at the end of the long connecting arm 14 away from the short connecting arm 12, and a linkage shaft 15 is provided at the end of the reciprocating rod 16 near the long connecting arm 14. The reciprocating rod 16 is movably connected to the long connecting arm 14 through the linkage shaft 15.

[0029] Limiting blocks 17 are provided on the other side of the integrated plate 5, and the reciprocating rod 16 is slidably connected to the limiting blocks 17;

[0030] After the filter press finishes its filtration process, sludge cakes will adhere to the surface of the filter plate 4. When it is necessary to clean these sludge cakes, the second stepper motor 9 is turned on, which drives the first lead screw 7 to rotate. With the first lead screw 7 threadedly connected to the first threaded sleeve 6, the first lead screw 7 moves the integrated plate 5 through the first threaded sleeve 6. The integrated plate 5 then moves the reciprocating rod 16 to the lower ends of both sides of the filter plate 4. The servo motor 10 is then turned on, which drives the drive shaft 11 to rotate. The drive shaft 11 then drives the short connecting arm 12 to rotate, and the short connecting arm 12 drives the long connecting arm 14 to reciprocate through the hinge shaft 13. With the sliding engagement of the reciprocating rod 16 and the limiting block 17, the long connecting arm 14 drives the reciprocating rod 16 to slide back and forth inside the limiting block 17 via the linkage shaft 15. The reciprocating rod 16 reciprocates and taps the filter plate 4 to knock off the sludge cake adhering to the surface of the filter plate 4. At the same time, under the continuous action of the second stepper motor 9, the integrated plate 5 is driven to move continuously, thereby moving and tapping multiple sets of filter plates 4 in sequence to clean them. This realizes the reciprocating tapping of the filter plates to detach the sludge cake from the filter plates, which facilitates the sequential movement and tapping of multiple sets of filter plates and improves the convenience of filter plate tapping and cleaning.

[0031] A second integrated frame 18 is symmetrically installed on the inner wall of the material box 2, and a second lead screw 19 is movably installed inside the second integrated frame 18.

[0032] The first stepper motor 8 is installed on the outer wall of the material box 2 on one side of the second integrated frame 18. The first stepper motor 8 plays the role of power drive, and the output end of the first stepper motor 8 is connected to the second lead screw 19.

[0033] The surface of the second lead screw 19 is fitted with a second threaded sleeve 21, and the second threaded sleeve 21 is threadedly connected to the second lead screw 19. A scraper 20 is slidably arranged inside the material box 2, and the scraper 20 is connected to the second threaded sleeve 21.

[0034] After the sludge cake is broken up by vibration, it will fall into the inside of the material box 2. In order to clean it better, the first step motor 8 is turned on, which drives the second lead screw 19 to rotate. With the threaded connection between the second lead screw 19 and the second threaded sleeve 21, the second lead screw 19 drives the second threaded sleeve 21 to move, and the second threaded sleeve 21 drives the scraper 20 to move. The scraper 20 scrapes the sludge inside the material box 2, and after the sludge is scraped into a pile, it can be cleaned quickly to improve the efficiency of sludge cleaning.

[0035] Work steps

[0036] After the filter press finishes its filtration process, sludge cakes will adhere to the surface of the filter plate 4. When it is necessary to clean these sludge cakes, the second stepper motor 9 drives the first lead screw 7 to rotate. The first lead screw 7 moves the integrated plate 5 through the first threaded sleeve 6. The integrated plate 5 moves the reciprocating rod 16 to the lower ends of both sides of the filter plate 4. The servo motor 10 drives the drive shaft 11 to rotate. The drive shaft 11 drives the short connecting arm 12 to rotate. The short connecting arm 12 drives the long connecting arm 14 to swing back and forth through the hinge shaft 13. The long connecting arm 14 drives the reciprocating rod 16 to slide back and forth inside the limit block 17 through the linkage shaft 15. The reciprocating rod 16 reciprocates and taps the filter plate 4 to remove the sludge cakes. The sludge cakes adhering to the surface of the filter plate 4 are shaken off. At the same time, under the continuous action of the second stepper motor 9, the integrated plate 5 is continuously moved, thereby moving and shaking multiple sets of filter plates 4 in sequence to clean them. After the sludge cakes are shaken apart, they fall into the inside of the material box 2. In order to clean them better, the first stepper motor 8 drives the second lead screw 19 to rotate, the second lead screw 19 drives the second threaded sleeve 21 to move, and the second threaded sleeve 21 drives the scraper 20 to move. The scraper 20 scrapes the sludge inside the material box 2, and after the sludge is scraped into a pile, it can be quickly cleaned. The above is the complete usage of the filter press with rapid vibration unloading.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
