Description

Technical Field

[0001] The utility model belongs to the technical field of filter presses, and particularly relates to a discharging device applicable to a filter press and a filter press. Background Technique

[0002] A filter press mainly consists of parts such as filter plates, a frame, a hydraulic system, and an electrical control system. For example, a diaphragm filter press, as a common solid-liquid separation device, is often used to separate suspended substances from liquids. Specifically, a mixture to be treated is injected into the filter plates, and under the action of an external force, the filtrate flows out through the filter plates, while the solid particles remain on the filter plates to form filter cakes. After the filter cakes are formed, pressure can be continuously applied to improve the solid-liquid separation effect, and finally, dry solid substances and clarified liquids are obtained. Further, after using the filter press to achieve solid-liquid separation, in order to facilitate the next use, it is usually necessary to clean the filter cakes formed on the filter plates. However, existing filter presses usually do not have the function of rapid discharging, so that the filter cakes can only naturally fall off from the filter plates. In this way, not only does it lead to low discharging efficiency, but also it is easy to have some filter cakes remaining on the filter plates after discharging, so that workers need to manually clean the remaining filter cakes on the filter plates again, which makes the workers time-consuming and laborious and reduces the production efficiency of the filter press.

[0003] In response to the above problems, some researchers have proposed discharging devices for improving discharging efficiency, mainly including the following two methods: One is to design a toothed moving track on the frame. During the discharging process, when the filter plates slide on the toothed moving track, they vibrate up and down, thereby improving the falling-off efficiency of the filter cakes. However, this method still has the following problems: (a1) The amplitude of up and down vibration is small, and the falling-off rate of the filter cakes is low. Especially for filter cakes with high viscosity, there are still defects such as incomplete falling-off or even inability to fall off, and manual cleaning is still required, resulting in low operation efficiency; (a2) The filter plates slide on the toothed moving track, and the required energy consumption is high; (a3) The toothed moving track is easily damaged, difficult to maintain, and has a high maintenance cost. The other is to arrange a vibrating mechanism below the filter plates. By using the vibrating mechanism to strike the filter plates, the filter cakes are made to fall off from the filter plates. However, the vibrating mechanism still needs to be improved in the following aspects: (b1) The vibrating cylinder swings within a certain angle range, and drives the vibrating pipe to strike the bottom of the filter plates through a pin shaft and a connecting plate, having defects such as small striking amplitude, low vibration frequency, and high energy consumption. It not only easily causes high-viscosity filter cakes to be unable to be smoothly unloaded from the filter cloth, resulting in low discharging rate and affecting the subsequent filter pressing effect, but also consumes more electric energy, resulting in a very high treatment cost; (b2) Using the vibrating cylinder to drive the vibrating pipe to strike the bottom of the filter plates not only has a large amount of work and low operation efficiency, but also easily causes the filter cakes to fall on the vibrating pipes, resulting in corrosion and damage of the vibrating pipes; (b3) The adopted vibrating mechanism has a complex structure, is easily worn, has a high maintenance cost, and a low service life.

[0004] Therefore, it is necessary to propose a discharge device applicable to a filter press with high vibration utilization rate, low energy consumption, simple structure and low maintenance cost, which is of great significance for improving the processing efficiency of the filter press and promoting the wide application of the filter press.

[0034] As Figures 1 to 3 shown, in this embodiment, it further includes a main beam for installing the filter plate 1 and four second support legs 14 for supporting the main beam. Both ends of the striking strip 409 are connected with elastic components 410, and the middle part is a convex part. The elastic components 410 are installed on the second support legs 14, so that the convex part of the striking strip 409 fits on the filter plate 1.

[0035] As Figures 1 to 3 shown, in this embodiment, a striking plate 411 is further provided at one end of the striking strip 409. During operation, the driving component strikes the striking plate 411 to make the striking strip 409 vibrate and strike the filter plate 1.

[0036] In this embodiment, the elastic component 410 is a spring.

[0037] In this embodiment, the spring adopted has a large elastic coefficient, mainly playing a reset role, and can drive the striking strip 409 to vibrate as the striking plate 411 moves.

[0038] As Figures 1 to 3 shown, in this embodiment, the driving component includes a support platform 3, a transmission mechanism 4 and a first motor 5, wherein the support platform 3 is installed on the main beam.

[0039] As Figures 1 to 3 shown, in this embodiment, the transmission mechanism 4 includes a rotating disk 401, a connecting column 402, a first sprocket 403, a U-shaped plate 404, an eccentric rod 405, a guide ring 406, a striking rod 407, and a support frame 408. The U-shaped plate 404 is installed on the lower surface of the support table 3. After the connecting column 402 passes through the U-shaped plate 404, both ends are fixedly connected to the rotating disk 401 and the first sprocket 403. One side of the rotating disk 401 close to the filter press body is fixedly connected to the eccentric rod 405, and the eccentric rod 405 is fixedly connected to the outer circumference of the rotating disk 401. The other end of the eccentric rod 405 is slidably connected to the guide ring 406. Both sides of the guide ring 406 are fixedly connected to two striking rods 407.

Further, under the pulling force of the spring, the filter plates 1 of the filter press can be oscillated through the striking strip 409, so that the filter cake in the filter plates 1 can quickly fall off, thereby achieving relatively fast unloading.

[0044] The discharging device of the present utility model symmetrically arranges striking bars on both sides of a filter press body composed of a plurality of filter plates, and uses a driving assembly to drive the striking bars to vibrate, thereby using the striking bars to strike the filter plates to complete the rapid discharging of the filter cake in the filter plates, having the following advantages: (a) Using the driving assembly to drive the striking bars to vibrate can link the striking bars to directly vibrate and strike the filter plates.

On the one hand, the vibration energy can be more effectively utilized, enabling the vibration force to be directly transmitted to the filter plates, which is more conducive to improving the discharging effect and discharging efficiency of the device. On the other hand, under the action of the elastic components, the striking bars can vibrate and strike the filter plates multiple times, thereby also significantly improving the discharging effect and discharging efficiency of the device. Compared with the conventional vibrating discharging device, the discharging device of the present utility model can not only effectively improve the discharging effect and discharging efficiency, but also effectively reduce the workload and working intensity of the staff, being more time-saving and labor-saving. At the same time, it is also beneficial to improving the working efficiency of the filter press, having advantages such as high vibration utilization rate, low energy consumption, simple structure, and low maintenance cost.
