Description

Technical Field

[0001] The utility model relates to a discharging structure for a filter press. Background Art

[0002] A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment. After the filter press completes the filtration, it is necessary to use a discharging structure to separate the filter plates that are tightly attached to each other, so that the filter cakes between the filter plates fall off before the next filtration can be carried out. The discharging structure of many existing filter presses usually separates the filter plates and allows the filter cakes to fall off by their own gravity. However, the small volume of filter cake located in the corner of the filter press cavity of the filter plate is difficult to separate by its own gravity, resulting in incomplete discharge of the filter press and easy clogging of the corner of the filter press cavity of the filter plate. Therefore, it is necessary to develop a discharging structure for a filter press to solve the above problems. Utility Model Content

A unloading component 13 is provided in the mounting box 12, and the unloading component 13 includes a clamping plate 16, a clamping plate 2 17 and a bidirectional threaded rod 20. The bidirectional threaded rod 20 is rotatably arranged in the mounting box 12, and the bidirectional threaded rod 20 is provided with two sections of threads in opposite directions. The clamping plate 16 and the clamping plate 2 17 are arranged on the bidirectional threaded rod 20, and a shaking component 18 is provided on one side of the clamping plate 16, and a connecting groove 19 is provided on one side of the clamping plate 2 17; the clamping plate 16 and the clamping plate 2 17 can be used to restrict the filter plate between the two. When the mounting box 12 moves, the clamping plate 16 and the clamping plate 2 17 will move with the filter plate, so that the filter plate is separated from the adjacent filter plate.

[0018] Furthermore, the shaking assembly 18 includes a base 22, which is fixed on one side of the splint 16. A groove 23 is provided in the base 22, and a magnet slider 24 is slidably provided in the groove 23. An electromagnet 25 is provided at the bottom of the groove 23, and a spring is connected between the magnet slider 24 and the electromagnet 25. A rubber pad 26 is provided on the top of the magnet slider 24; the base 22 corresponds to the connecting groove 19, and when the splint 16 and the splint 2 17 are close to each other, the base 22 will be inserted into the connecting groove 19.

[0019] Furthermore, a motor 21 is provided on one side of the installation box 12 , and an output shaft of the motor 21 is connected to the bidirectional threaded rod 20 .

[0020] Furthermore, the motion component 15 includes an L-shaped plate 27, which is arranged on the lower side of the installation box 12. A motion groove 28 is provided on one side of the L-shaped plate 27. A threaded rod 30 is rotatably arranged in the motion groove 28. A motion block 29 is provided on the threaded rod 30. The motion block 29 is connected to the inner wall of the gantry 11. A motor 2 31 is provided on one side of the L-shaped plate 27, and the output shaft of the motor 2 31 is connected to the threaded rod 30.

[0021] Furthermore, a support rod 14 is connected between the bottom of the installation box 12 and the inner wall of the gantry 11 ; the support rod 14 provides support for the installation box 12 .

[0022] The working principle of the utility model is that when installing the discharge structure of the utility model, the horizontal part of the L-shaped plate 27 is connected to the bottom of the filter press crossbeam by bolts. At this time, the installation box 12 is located on one side of the crossbeam, and the wing plate of the filter plate slidably arranged on the crossbeam of the filter press is located on the upper side of the discharge assembly 13; when discharging, the motor 2 31 is started to rotate the threaded rod 30, so that the moving block 29 moves in the moving groove 28, so that the gantry 11 moves along the L-shaped plate 27 in the direction close to the filter plate, and the installation box 12 and the discharge assembly 13 move accordingly, and the discharge assembly 13 is moved to the lower side of the wing plate of a filter plate, so that the wing plate of the filter plate is located between the clamping plate 16 and the clamping plate 2 17, and at this time, the motor 1 21 is started to rotate the bidirectional threaded rod 20, so that the clamping plate 1 6 and the second clamping plate 17 are close to each other, so that the wing plate of the filter plate is restricted between the first clamping plate 16 and the second clamping plate 17, and the wing plate of the filter plate is fitted with the rubber pad 26 on the top of the magnet slider 24. At this time, the motor 2 31 is started in reverse to make the unloading assembly 13 move the filter plate back, so that this filter plate is separated from the filter plate on its side, and most of the filter cake between the two filter plates is detached. When the electromagnet 25 is energized, the electromagnet 25 uses magnetic force to repel the magnet slider 24, so that the magnet slider 24 rises, and the filter plate rises accordingly. When the electromagnet 25 is powered off, the magnetic force disappears, and the magnet slider 24 falls under the action of the spring, and the filter plate falls accordingly. Periodically energizing the electromagnet 25 can make the filter plate shake up and down, thereby shaking off the filter plate remaining in the filter pressing chamber of the filter plate, ensuring complete unloading.

[0023] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
