Description

Technical Field

[0001] This application relates to the manufacturing technology of filter press equipment, and more particularly to a filter press assembly and a filter press. Background Technology

[0002] A filter press is a mechanical device that effectively separates solid particles from liquid in a suspension by applying external pressure. It is widely used in industries such as mining, chemical, pharmaceutical, metallurgy, food, and environmental protection.

[0003] In related technical solutions, a filter press forms a filter chamber by the contact of two opposing filter plates. Specifically, each filter plate has a groove, and a filter cloth is placed within the groove. The grooves on the two filter plates are positioned opposite each other, thus forming a filter chamber upon contact. The filter plates also have feed holes through which fluid enters the filter chamber. During the filtration process, the liquid in the fluid is squeezed out of the filter chamber, and the remaining solids form a filter cake within the filter chamber. After filtration is complete, the filter cake is dropped off by pulling apart the filter plates.

[0004] However, with the use of related technologies, some filter cake may stick to the filter cloth and cannot be completely removed, thus creating a safety hazard. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the related technologies, the purpose of this application is to provide a filter press assembly and a filter press. This application is beneficial to reducing the probability of filter cake sticking to the filter bag, thereby improving the safety of the filter press.

[0017] The first elastic block is disposed on the first filter plate along the third direction, and the second elastic block is disposed on the second filter plate along the third direction.

[0018] In one possible implementation, the first elastic block and the second elastic block correspond one-to-one;

[0019] Alternatively, the first elastic block and the second elastic block can be arranged alternately.

[0020] In one possible implementation, the first filter plate is provided with a first mounting groove, and the first elastic block is interference-fitted with the first mounting groove;

[0024] In one possible implementation, a plurality of first elastic blocks are spaced apart on the first filter plate, and a plurality of second elastic blocks are spaced apart on the second filter plate.

[0025] On the other hand, this application provides a filter press, including a frame on which a plurality of filter pressing components as described above are provided. The frame is also provided with a track and a vibrating device, which can slide along the track and is used to separate the filter bag from the filter cake.

[0026] In one possible implementation, the vibratory device includes a lifting mechanism, a track trolley mechanism, and a roller mechanism. The roller mechanism is disposed on the output end of the lifting mechanism, and the track trolley mechanism is disposed on one side of the lifting mechanism. The lifting mechanism is slidably connected to the track through the track trolley mechanism.

[0027] The lifting mechanism can lift the roller mechanism so that the roller mechanism lifts the filter press assembly.

[0028] In one possible implementation, the vibratory device includes a support, a first track trolley mechanism, a second track trolley mechanism, and a power mechanism. The first track trolley mechanism and the second track trolley mechanism are respectively disposed on both sides of the support along a second direction.

The second filter plate is disposed on a second side of the filter bag, and at least one second elastic block is provided on the side of the second filter plate facing the filter bag. The first and second elastic blocks respectively abut against both sides of the filter bag, thereby dividing the cavity into multiple continuous sub-cavities. This application divides the cavity of the filter bag into multiple continuous sub-cavities by using the first elastic block on the first filter plate and the second elastic block on the second filter plate. This makes the thickness of the area corresponding to the first and second elastic blocks in the cavity less than the thickness of other areas, creating weak points when the filter cake is broken. This facilitates the breakage of the filter cake during subsequent vibration, reduces the probability of the filter cake sticking to the filter bag, and thus improves the safety of the filter press.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0052] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] As described in the background section, in related technologies, a filter press forms a filter chamber by two opposing filter plates coming together. During filtration, the liquid in the fluid is squeezed out of the filter chamber, and the remaining solids form a filter cake inside. After filtration is complete, the filter cake is dropped off by pulling apart the filter plates. However, with this technology, some filter cake may adhere to the filter cloth and cannot be completely removed, thus posing a safety hazard.

[0054] In view of this, the embodiments of this application aim to provide a filter press assembly and a filter press, which, by setting at least one filter bag, a first filter plate and a second filter plate, forms a cavity inside the filter bag; a first elastic block on the first filter plate and a second elastic block on the second filter plate divide the cavity of the filter bag into multiple continuous sub-cavities, such that the thickness of the cavity and the area corresponding to the first elastic block and the second elastic block is less than the thickness of other areas, becoming a weak point when the filter cake is broken, which facilitates the breakage of the filter cake during subsequent vibration, reduces the probability of the filter cake sticking to the filter bag, and thus improves the safety of the filter press.

[0055] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the content of this application. It should be noted that, in the description of this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other, and the third direction Z can be, for example, a vertical direction.

[0056] Please refer to Figures 1-3 This embodiment provides a filter press assembly 10, including:

[0057] At least one filter bag 100, exemplary of which, the filter bag 100 may be made of high-strength filter cloth, enabling it to withstand strong pressure without rupture. The specific material of the filter bag 100 can be determined as needed. A cavity is formed inside the filter bag 100 to facilitate the injection of coal slurry into it. The number of filter bags 100 can be determined as needed, for example, one or two.

[0058] A first filter plate 200 is disposed on the first side of the filter bag 100, and at least one first elastic block 210 is provided on the side of the first filter plate 200 facing the filter bag 100. In this embodiment, the first filter plate 200 may be made of metal material, thereby giving it high rigidity. The first elastic block 210 is fixedly connected to the first filter plate 200, and the specific connection method can be determined as needed.

[0059] The second filter plate 300 is disposed on the second side of the filter bag 100, and at least one second elastic block 310 is provided on the side of the second filter plate 300 facing the filter bag 100. In this embodiment, the second filter plate 300 can adopt a structure similar to the first filter plate 200 to reduce manufacturing difficulty. The second filter plate 300 can be made of metal material, thereby giving it high rigidity. The second elastic block 310 is fixedly connected to the second filter plate 300, and the specific connection method can be determined as needed.

[0060] During the filter press process, the first elastic block 210 and the second elastic block 310 abut against both sides of the filter bag 100, thereby dividing the cavity into multiple continuous sub-cavities. In this embodiment, the first elastic block 210 and the second elastic block 310 can be made of a material with an elastic modulus lower than that of the filter bag 100. During filter press, the first elastic block 210 and the second elastic block 310 can absorb part of the deformation of the filter cake, reducing the pressure of the filter cake on the filter bag 100. Specifically, as shown... Figure 3 As shown, after the filter bag 100 is compressed by the first elastic block 210 and the second elastic block 310, the filter cake 1000 inside it deforms, forming a locally thinner area. This area is located between two adjacent sub-cavities. Because this area is thinner, it is easier to break during subsequent vibration, thus reducing the probability of the filter cake 1000 sticking to the filter bag 100 and improving the safety of the filter press.

[0061] As described above, in this embodiment, the cavity of the filter bag 100 is divided into multiple continuous sub-cavities by the first elastic block 210 on the first filter plate 200 and the second elastic block 310 on the second filter plate 300. This makes the thickness of the cavity and the corresponding area of ​​the first elastic block 210 and the second elastic block 310 less than the thickness of other areas, which becomes the weak point when the filter cake 1000 is broken. This makes it easier for the filter cake 1000 to be broken during subsequent vibration, reducing the probability of the filter cake 1000 sticking to the filter bag 100, thereby improving the safety of the filter press.

[0062] Please continue to refer to Figure 1 In this embodiment, the first filter plate 200 and the second filter plate 300 are respectively disposed on both sides of the filter bag 100 along the first direction X.

[0063] In one possible implementation, the first elastic block 210 of this embodiment is disposed on the first filter plate 200 along the second direction Y, and the second elastic block 310 is disposed on the second filter plate 300 along the second direction Y. With the above structure, the cavity inside the filter bag 100 can be divided into multiple sub-cavities disposed along the third direction Z, thereby facilitating the breakage of the filter cake 1000 during subsequent vibration, reducing the probability of the filter cake 1000 adhering to the filter bag 1000, and thus improving the safety of the filter press.

[0064] In another possible implementation, the first elastic block 210 of this embodiment is disposed on the first filter plate 200 along the third direction Z, and the second elastic block 310 is disposed on the second filter plate 300 along the third direction Z. With the above structure, the cavity inside the filter bag 100 can be divided into multiple sub-cavities disposed along the second direction Y, thereby facilitating the breakage of the filter cake 1000 during subsequent vibration, reducing the probability of the filter cake 1000 adhering to the filter bag 1000, and thus improving the safety of the filter press.

[0065] In another possible implementation, the first elastic block 210 of this embodiment is inclined to the second direction Y and the third direction Z on the first filter plate 200, and the second elastic block 310 is inclined to the second direction Y and the third direction Z on the second filter plate 300. That is, the first elastic block 210 and the second elastic block 310 of this embodiment can also be inclined, thereby dividing the cavity inside the filter bag 100 into multiple inclined sub-cavities, which facilitates the breakage of the filter cake 1000 during subsequent vibration, reduces the probability of the filter cake 1000 sticking to the filter bag 100, and thus improves the safety of the filter press.

[0066] like Figure 1 As shown, preferably, the filter bag 100 in this embodiment is provided with a discharge port, which is located at one end of the filter bag 100 along the third direction Z, so as to facilitate the separation of the filter cake 1000 from the filter bag 100 by gravity or other forces.

[0067] The first elastic block 210 is disposed on the first filter plate 200 along the third direction Z, and the second elastic block 310 is disposed on the second filter plate 300 along the third direction Z. The filter bag 100 is divided into multiple sub-cavities disposed along the second direction Y, which facilitates the breakage of the filter cake 1000 during subsequent vibration, reduces the probability of the filter cake 1000 sticking to the filter bag 100, and thus improves the safety of the filter press.

[0068] Please continue to refer to Figure 1 In this embodiment, the first elastic block 210 and the second elastic block 310 can correspond one-to-one, so that they can jointly abut against the filter bag 100 on opposite sides, which is beneficial to reduce the thickness of the filter cake 1000 in this area.

[0069] In other possible implementations, the first elastic block 210 and the second elastic block 310 of this embodiment can also be arranged alternately. This structure can also divide the cavity inside the filter bag 100 into multiple continuous sub-cavities, thereby reducing the probability of the filter cake 1000 sticking to the filter bag 100 and improving the safety of the filter press.

[0070] Please continue to refer to Figure 2 In this embodiment, the first filter plate 200 is provided with a first mounting groove, and the first elastic block 210 is interference-fitted with the first mounting groove. Specifically, the first mounting groove can be, for example, a dovetail groove, and the first elastic block 210 is partially pressed into the dovetail groove, thereby achieving an interference fit with the first filter plate 200.

[0071] Similarly, the second filter plate 300 is provided with a second mounting groove, and the second elastic block 310 is interference-fitted with the second mounting groove. Specifically, the second mounting groove can be, for example, a dovetail groove, and the second elastic block 310 is partially pressed into the dovetail groove, thereby achieving an interference fit with the second filter plate 300.

[0072] Furthermore, the first elastic block 210 in this embodiment includes either a polyurethane block or a rubber block. The second elastic block 310 may also include either a polyurethane block or a rubber block. It is understood that the hardness of the first elastic block 210 and the second elastic block 310 can also be adjusted according to the coal slime pressure filter.

[0073] The first elastic block 210 is prism-shaped or cylindrical, and the second elastic block 310 is prism-shaped or cylindrical. The specific shapes of the first elastic block 210 and the second elastic block 310 can be set as needed. The shape of the first elastic block 210 and the shape of the second elastic block 310 can be the same or different.

[0074] In this embodiment, a plurality of first elastic blocks 210 may be spaced apart on the first filter plate 200, and a plurality of second elastic blocks 310 may be spaced apart on the second filter plate 300. By setting a plurality of first elastic blocks 210 and a plurality of second elastic blocks 310, the number of sub-cavities inside the filter bag 100 can be increased, thereby facilitating the separation of the filter cake 1000 from the filter bag 100, reducing the probability of the filter cake 1000 sticking to the filter bag 100, and improving the safety of the filter press.

[0075] Please continue to refer to Figures 4-8 This embodiment also provides a filter press, including a frame 20, on which a plurality of the above-mentioned filter press components 10 are provided. The frame 20 is also provided with a track 30 and a vibrating device 40. The vibrating device 40 can slide along the track 30 and is used to separate the filter bag 100 from the filter cake 1000.

[0076] It is understood that, since the filter press of this embodiment uses the above-mentioned filter press component 10, it can reduce the probability of filter cake sticking to the filter bag, which is beneficial to improving the safety of the filter press.

[0077] Please continue to refer to Figure 4 and Figure 5 In one possible implementation, the vibrating device 40 of this embodiment includes a lifting mechanism 41, a track trolley mechanism 42, and a roller mechanism 43. The roller mechanism 43 is disposed on the output end of the lifting mechanism 41, which may include components such as a pneumatic cylinder or a hydraulic cylinder. The track trolley mechanism 42 is disposed on one side of the lifting mechanism 41, and the lifting mechanism 41 is slidably connected to the track 30 through the track trolley mechanism 42, thereby driving the vibrating device 40 to move along the frame 20.

[0078] In this embodiment, the lifting mechanism 41 can lift the roller mechanism 43 to raise the filter press assembly 10. Specifically, in use, the track trolley mechanism 42 first drives the vibrating device 40 to the designated area below the filter press assembly 10. Then, the lifting mechanism 41 lifts the roller mechanism 43, thereby detaching the filter press assembly 10 from the frame 20. Then, the track trolley mechanism 42 drives the vibrating device 40 to continue moving, and the filter press assembly 10 lifted by the roller mechanism 43 also moves with the vibrating device 40, colliding with another filter press assembly 10 still on the frame 20. Since the vibrating device 40 continues to move forward driven by the track trolley mechanism 42, the filter press assembly 10 on the roller mechanism 43 will fall back onto the frame 20 after being collided with it, causing the filter cake in the filter bag of the filter press assembly 10 to fall off. Finally, the lifting mechanism 41 lowers, causing the roller mechanism 43 to lower, and the vibrating device 40 returns to its initial state. The above process is repeated until all vibrating requirements are met.

[0079] In this embodiment, multiple filter press components 10 can be vibrated by adjusting the length of the roller mechanism 43.

[0080] Please continue to refer to Figures 6-8 In another possible implementation, the vibrating device 40 of this embodiment includes a support 44, a first track trolley mechanism 45, a second track trolley mechanism 46, and a power mechanism 47. The first track trolley mechanism 45 and the second track trolley mechanism 46 are respectively disposed on both sides of the support 44 along the second direction Y. The track 30 includes a first track and a second track disposed on both sides of the frame 20 along the second direction Y. The first track trolley mechanism 45 is slidably disposed on the first track, and the second track trolley mechanism 46 is slidably disposed on the second track.

[0081] Please continue to refer to Figure 8 This embodiment also includes a suspension device 50, which includes a filter bag rod 51, a guide rod 52, a fixing block 53, and a spring 54. The guide rod 52 is disposed on both sides of the filter bag rod 51 along the second direction Y. The first end of the guide rod 52 is connected to the filter bag rod 51, and the second end of the guide rod 52 is connected to the fixing block 53. The two ends of the spring 54 abut against the filter bag rod 51 and the fixing block 53, respectively. The filter bag 100 of the filter pressing assembly 10 is suspended on the filter bag rod 51.

[0082] In this embodiment, the power mechanism 47 is located in the middle of the support 44 and on the side of the support 44 facing the filter bag 100 rod. The number of power mechanisms 47 can be set as needed. For example, two power mechanisms 47 can be set. The power mechanism 47 can extend and retract along the third direction Z to abut against the filter bag rod 51. The power mechanism 47 may include, for example, a pneumatic cylinder or a hydraulic cylinder.

[0083] In this embodiment, the first track trolley mechanism 45 and the second track trolley mechanism 46 first drive the vibrating device 40 to the designated position above the filter press assembly 10. Then, the power mechanism 47 extends downwards, abutting against the filter bag rod 51, and compresses the suspension device 50 and the filter press assembly 10 downwards by a certain distance. Next, the first track trolley mechanism 45 and the second track trolley mechanism 46 drive the vibrating device 40 to continue moving, causing the power mechanism 47 to separate from the suspension device 50. Under the elastic restoring force of the spring 54 of the suspension device 50, the suspension device 50 quickly rebounds, driving the filter bag upwards. Friction is generated between the filter cake inside the filter bag and the filter bag, causing the filter cake to fall out of the filter bag, completing one vibrating cycle. The above process is repeated until all vibrating requirements are met.
