Description

Technical Field

[0002] The filter press uses a special filter medium to apply a certain pressure to the object, causing the liquid to seep out. It is a mechanical device that is commonly used in solid-liquid separation equipment. As a mature dehydration equipment, the filter press is widely used in the field of environmental protection and has become an important equipment for sewage sludge treatment.

[0003] The filtrate enters the filter press under the pressure of the feed pump. The filter medium intercepts the particles in the filtrate through the filter cloth, forming a filter cake in the filter chamber. The filtrate is discharged through the outlet holes of the filter plates. When the pressure reaches the set pressure, the filter cake is formed in the filter chamber, the feed pump stops, the compression plate is loosened, and the filter plates are pulled apart piece by piece to remove the filter cake in the filter chamber. After the filter plates are gradually pulled apart, the filter cake falls directly. However, the filter cake is in a wet state and has a certain adsorption capacity, which causes the filter cake to not fall all easily, affecting the subsequent use of the filter press. Therefore, a leak-proof and sealed filter press is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2The utility model provides an embodiment: a leak-proof and sealed filter press, including a bracket 1, a pressure plate 2 is arranged inside the bracket 1, a hydraulic press 3 is fixedly connected to the inside of the bracket 1, the output end of the hydraulic press 3 is connected to the pressure plate 2, a filter press plate 4 is arranged inside the bracket 1, and a vibration component is arranged on the side wall of the filter press plate 4, a fixed rod 5 is fixedly connected to the inside of the bracket 1, a slider 6 is slidably connected to the side wall of the fixed rod 5, the side wall of the slider 6 is fixedly connected to the side wall of the filter press plate 4, and the side wall of the filter press plate 4 is provided with a fixed component; the vibration component includes a connecting plate 26, and the side wall of the connecting plate 26 is fixedly connected to the bracket Inside the frame 1, the bottom of the filter press plate 4 is fixedly connected to a connecting block 7, the inside of the connecting plate 26 is fixedly connected to a round rod 8, the inside of the connecting block 7 is slidably connected to the side wall of the round rod 8, the side wall of the round rod 8 is sleeved with a first spring 9, one end of the first spring 9 is fixedly connected to the inside of the connecting plate 26, and the other end of the first spring 9 is fixedly connected to the side wall of the connecting block 7, the inside of the bracket 1 is rotatably connected to a rotating shaft 10, the side wall of the rotating shaft 10 is fixedly connected to an eccentric wheel 11, the side wall of the eccentric wheel 11 is in contact with the filter press plate 4, and a motor 12 is provided on the side wall of the bracket 1, and the output end of the motor 12 is connected to the rotating shaft 10;

[0033] After completing the filtration process, the hydraulic press 3 pulls open the filter press plate 4 through its mechanical device. At this time, the filter cake will fall from the filter press plate 4. However, there will often be some filter cake residues still adsorbed on the surface of the filter cloth 13. In order to remove these residues, the motor 12 is started. The operation of the motor 12 drives the rotating shaft 10 to rotate, and then the eccentric wheel 11 also starts to rotate. The rotation of the eccentric wheel 11 will knock on the filter press plate 4. These knocking actions cause the connecting block 7 fixed at the bottom to slide on the side wall of the round rod 8. During the sliding process, the connecting block 7 will apply pressure to the first spring 9, causing the first spring 9 to perform telescopic movement. The filter press plate 4 shakes so that the filter cake residue remaining on the filter cloth 13 falls off, ensuring that the filter press can smoothly perform the next filtration operation.

[0034] Reference Figure 1 - Figure 4The fixed assembly includes a filter cloth 13, the side wall of the filter cloth 13 is fixedly connected to the inside of the filter press plate 4, the side wall of the filter press plate 4 is fixedly connected to a fixed frame 14, the side wall of the filter press plate 4 is fixedly connected to a fixed plate 15, a screw 16 is provided inside the fixed plate 15, the screw 16 passes through the fixed plate 15 and extends to the inside of the fixed frame 14, the side wall of the screw 16 is threadedly connected to a rotating block 17, the side wall of the rotating block 17 is fixedly connected to a connecting rod 18, the screw 16 is slidably connected to a push rod 19, the side wall of the push rod 19 is fixedly connected to a fixed block 20, and the fixed block The side wall of 20 slides inside the screw rod 16, and a card plate 21 is rotatably connected inside the fixed block 20. A card block 22 is fixedly connected to the lower surface of the screw rod 16, and a vertical slot 23 is opened inside the card block 22. A sliding rod 24 is fixedly connected to the bottom of the push rod 19, and a second spring 25 is sleeved on the side wall of the slide rod 24. One end of the second spring 25 is fixedly connected to the side wall of the push rod 19, and the other end of the second spring 25 is fixedly connected to the inside of the card block 22. One end of the push rod 19 is slidably connected to the inside of the card block 22, and the side wall of the slide rod 24 is slidably connected to the inside of the vertical slot 23;

[0035] When performing the fixing operation of the filter cloth 13, first move it downward by pressing the push rod 19. As the push rod 19 descends, the second spring 25 is compressed by pressure, and this pressure causes the fixing block 20 to enter the interior of the block 22. At the same time, the card plate 21 will also fit tightly against the side wall of the screw 16. When the screw 16 is inserted into the interior of the fixing plate 15, ensure that the screw 16 is in place. After the screw 16 is in place, the push rod 19 can be released. At this time, the second spring 25 loses its extrusion and begins to reset. As the second spring 25 resets, the fixing block 20 withdraws from the interior of the block 22, so that the card plate 21 opens and rests against the interior of the fixed frame 14. Then, the rotating block 17 is rotated to the surface of the fixing plate 15 by rotating the connecting rod 18, so that the filter cloth 13 can be fixed to the interior of the filter press plate 4, completing the installation of the filter cloth 13.

[0036] Working principle: When the filter press plate 4 is pulled open, part of the filter cake residue is adsorbed on the filter cloth 13. By starting the motor 12 to rotate the rotating shaft 10, the eccentric wheel 11 is driven to rotate and knock the filter press plate 4, so that the connecting block 7 slides on the side wall of the round rod 8. The shaking of the connecting block 7 squeezes the first spring 9, causing the first spring 9 to perform telescopic movement. The filter press plate 4 causes the residue to fall off during the shaking, ensuring the normal operation of the filter press.

[0037] When installing the filter cloth 13, the push rod 19 is pressed downward to move the second spring 25 under pressure and compressed. As the push rod 19 moves, the fixing block 20 enters the interior of the block 22, and the card plate 21 is also tightly fitted to the side wall of the screw 16. After the screw 16 is inserted into the interior of the fixed plate 15, the push rod 19 is released to release the pressure of the second spring 25 to reset, so that the fixing block 20 is disengaged from the interior of the block 22, and the card plate 21 is also opened and abuts against the interior of the fixed frame 14. Then, by rotating the connecting rod 18, the rotating block 17 is driven to rotate to the surface of the fixed plate 15, and the filter press plate 4 is fixed, thereby completing the fixation of the filter cloth 13.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
