Description

Technical Field

[0001] The utility model relates to the field of filter presses, in particular to a filter press component and a filter press. Background Art

[0002] Filter press is a commonly used solid-liquid separation equipment, widely used in coal, mining, chemical, pharmaceutical, food and environmental protection industries.

[0003] When used in an existing filter press, two adjacent filter plates are generally closed by external filter pressing to form a filter chamber. When the material to be filtered is passed into the filter chamber from one end, the liquid penetrates the filter plate under the action of the feed pressure, while the solid particles are trapped on the filter cloth, gradually forming a layer of filter cake. However, the separation of the filtrate is achieved by relying on the opposite effects of the pressing and sealing forces. As the feed volume increases and the amount of material to be filtered increases, the filtration efficiency will also decrease. Utility Model Content

[0051] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0055] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0056] When used in an existing filter press, two adjacent filter plates are generally closed by external filter pressing to form a filter chamber. When the material to be filtered is passed into the filter chamber from one end, the liquid penetrates the filter plate under the action of the feed pressure, while the solid particles are trapped on the filter cloth, gradually forming a layer of filter cake. However, the separation of the filtrate is achieved by relying on the opposite effects of the pressing and sealing forces. As the feed volume increases and the amount of material to be filtered increases, the filtration efficiency will also decrease.

[0057] In view of this, the utility model provides a filter press assembly 100, including a filter bag 110, a partition assembly, a driving mechanism 130 and a sealing assembly, wherein the filter bag 110 is used to hold a filter material and has an opening at one end; the partition assembly includes at least two drainage partitions 120, each drainage partition 120 is arranged at intervals along a first direction X, and at least one filter bag 110 is arranged between two adjacent drainage partitions 120; the driving mechanism 130 includes a linkage assembly 131 and a first driving unit 132, the linkage assembly 131 is connected between each drainage partition 120, the first driving unit 132 is connected to the partition assembly, and the first driving unit 132 is used to drive each drainage partition 120 to move closer to or away from each other so as to filter the filter bag 110 through the drainage partition 120; the sealing assembly is used to seal or open the opening of the filter bag 110. When the filter press assembly 100 is working, the first driving unit 132 can be used to drive the partition assembly to move closer to each other. Since the linkage assembly 131 is connected between the drainage partitions 120, driven by the linkage assembly 131, the drainage partitions 120 can maintain equal spacing during movement, so that the pressure on each filter bag 110 is the same, thereby ensuring that the partition assembly can fully filter each filter bag 110, thereby improving the efficiency of the filter press. After the filter press is completed, the formed filter cake can be unloaded from the opening of the filter bag 110, and the operation is extremely convenient.

[0058] Figure 1 A schematic diagram of the overall structure of the filter press assembly provided in an embodiment of the utility model; Figure 2 for Figure 1 The enlarged view of point A in the middle; Figure 3 for Figure 1 The main view; Figure 4 The present invention is a schematic diagram of the overall structure of the filter press provided in the embodiment of the present invention.

[0059] You can refer to Figures 1 to 4 The embodiment of the utility model provides a filter press assembly 100, including a filter bag 110, a partition assembly, a driving mechanism 130 and a sealing assembly, wherein the filter bag 110 is used to hold a filter and has an opening at one end, the partition assembly includes at least two drainage partitions 120, each drainage partition 120 is arranged at intervals along a first direction X, and at least one filter bag 110 is arranged between two adjacent drainage partitions 120, wherein the first direction X is consistent with the thickness direction of the drainage partition 120; the driving mechanism 130 includes a linkage assembly 131 and a first driving unit 132, the linkage assembly 131 is connected between each drainage partition 120, the first driving unit 132 is connected to the partition assembly, the first driving unit 132 is used to drive each drainage partition 120 to move closer to or away from each other, so as to filter the filter bag 110 through the drainage partition 120, and the sealing assembly is used to seal or open the opening of the filter bag 110.

[0060] The drainage baffles 120 may be rectangular or square in shape as a whole, the filter bags 110 are sandwiched between the drainage baffles 120, and multiple filter bags 110 may be arranged between two drainage baffles 120, and multiple filter bags 110 are squeezed simultaneously through two drainage baffles 120 to simplify the overall structure of the filter bag 110 assembly. The simultaneous arrangement of multiple filter bags 110 can make the filter cake more uniform during the squeezing process, thereby improving the filter pressing efficiency and ensuring the consistency of the moisture content.

[0061] The opening on the filter bag 110 can be used for unloading the filter bag 110. It can be understood that the opening can be closed by a sealing assembly when the filter bag 110 contains the filter material, and opened for unloading when the drainage partitions 120 are separated from each other.

[0062] When the filter press assembly 100 provided by the embodiment of the utility model is working, the drainage baffles 120 can be driven to approach each other through the first driving unit 132. Since the linkage assembly 131 is connected between the drainage baffles 120, driven by the linkage assembly 131, the drainage baffles 120 can maintain equal spacing during the movement, so that the pressure on each filter bag 110 is the same, and the thickness of each filter bag 110 after feeding is equal, which improves the coordination of each drainage baffle 120 and improves the effect and efficiency of the filter press. After the filter press is completed, the moisture content of the formed filter cake is the same, and the material can be unloaded from the opening of the filter bag 110, which is extremely convenient to operate.

[0063] It should be noted that the traditional plate-frame filter press 200 works under low pressure, and its working principle is mainly to separate the filtrate through the opposite action of squeezing and sealing force. In high pressure scenes, the sealing difficulty of this equipment will also increase accordingly, and the material spraying phenomenon is prone to occur, which will not only affect the separation effect of the filtrate, but also make it difficult for the equipment to be operated unmanned. Secondly, the high pressure environment has high requirements for the rigidity and strength of the filter plate, so in terms of cost and equipment weight, the traditional plate-frame filter press 200 requires a greater investment. The bag filter press 200 designed in the embodiment of the utility model has a different working principle from the traditional plate-frame filter press 200, and does not need to rely on reverse pressure for sealing. In this way, the bag filter press 200 can not only maintain good sealing performance under high pressure, but also avoid the material spraying phenomenon, thereby improving the filtrate separation efficiency. In addition, the bag filter press 200 has relatively low requirements in terms of rigidity and strength, which reduces the cost and equipment weight, making it more suitable for various scenarios. Therefore, compared with the traditional plate and frame filter press 200, the bag filter press 200 provided in the embodiment of the utility model can not only solve the sealing and spraying problems and improve the filtrate separation effect, but also reduce the cost and equipment weight, realize unmanned operation, and has obvious advantages in high-pressure environments.

[0064] like Figure 1As shown, in the above embodiment, the first drive unit 132 can be connected to the two outermost drainage baffles 120 in the baffle assembly at both ends along its own expansion and contraction direction. It can be understood that when the baffle assembly includes multiple drainage baffles 120 (more than 3), the first drive unit 132 can squeeze the two outermost drainage baffles 120 from both sides, and the remaining drainage baffles 120 move synchronously with the two outermost drainage baffles 120 under the drive of the linkage assembly 131, so as to filter each filter bag 110. Among them, the first drive unit 132 can use a hydraulic cylinder as shown in Figure 1, and the two ends of the hydraulic cylinder are respectively connected to the two outermost drainage baffles 120 of the baffle assembly along the first direction X. In addition, the first drive unit 132 can also be a drive structure that drives the movement of the piston rod by pneumatic or electric means, or drives the chain drive, which is not specifically limited here.

[0065] In the above embodiment, first driving units 132 are provided on opposite sides of the partition assembly along the second direction Y, and the second direction Y is perpendicular to the first direction X. The first driving units 132 on both sides simultaneously drive the partition assembly to move, so that the partition assembly can move more stably.

[0066] In the above embodiment, the structure of the linkage assembly 131 can have various forms. For example, the linkage assembly 131 can include at least one hinge, which is in a rhombus shape, with four sides of the hinge hinged end to end, and two diagonal hinges of the hinge respectively hinged to two adjacent drainage baffles 120. When the drainage baffles 120 approach or move away from each other, the rhombus hinge is compressed or stretched accordingly. It can be understood that when the drainage baffles 120 approach or move away from each other, the length of the diagonal lines of each hinge along the first direction X can always remain consistent, so that the drainage baffles 120 can be kept equidistant. Specifically, the above hinge structure can be set on opposite sides of the baffle assembly, so that the structure of the baffle assembly is more stable.

[0067] For another example, the linkage assembly 131 may include multiple telescopic rods, each of which is disposed between two adjacent drainage baffles. When the drainage baffles 120 move closer to or away from each other, each of the telescopic rods contracts or extends accordingly. Of course, the linkage assembly 131 may also be structured in other forms, as long as the synchronous linkage of the drainage baffles 120 can be achieved.

[0068] In the above embodiment, the drainage baffle 120 may have a drainage channel on the side facing the filter bag 110, and the drainage channel is used to discharge the liquid generated after the drainage baffle 120 filters the filter bag 110. During the filtration process, the seeping filtrate can flow out from the drainage channel on the drainage baffle 120 in time to prevent the filtrate from remaining between the filter bag 110 and the drainage baffle 120 and then re-infiltrating into the filter cake. Therefore, by providing the drainage channel, the water content of the filter cake can be reduced, the filtration is more thorough, and the filtration efficiency is improved.

[0069] There are many ways to form the drainage passage. For example, the drainage baffle 120 may have a plurality of protrusions 121 on the side facing the filter bag 110, and there is a gap between two adjacent protrusions 121, so that the drainage channel is formed by the gap. For another example, the drainage baffle 120 may have a groove on the side facing the filter bag 110, and the two ends of the groove extend to the top and the bottom of the drainage baffle 120 respectively, so that the drainage channel is formed by the groove. Whether the drainage passage is formed by the gap between the protrusions 121 or the groove, the filtrate can be discharged in time, avoiding the filtrate from remaining between the drainage baffle 120 and the filter bag 110, so that when the drainage baffle 120 is separated, the remaining part of the filtrate re-infiltrates into the filter cake in the filter bag 110, resulting in incomplete filtration. It can be understood that in a set of baffle assemblies, the two outermost drainage baffles 120 are only provided with drainage channels on the side in contact with the filter bag 110, while the middle drainage baffle 120 is provided with drainage channels on both sides because both sides of the middle drainage baffle 120 are in contact with the filter bag 110.

[0070] In the above embodiment, the filter press assembly 100 may further include a first mounting seat 140 and a second mounting seat 150, which are respectively connected to opposite sides of the drainage baffle 120 along the second direction Y (each drainage baffle 120 is provided with a first mounting seat 140 and a second mounting seat 150), and the first mounting seat 140 and the second mounting seat 150 are used to movably set the filter press assembly 100 on the frame 210 of the filter press 200. It can be understood that the first mounting seat 140 and the second mounting seat 150 can serve as supporting connection points of each drainage baffle 120 on the frame of the filter press 200, and when the baffle assemblies are close to or separated from each other, each drainage baffle 120 can move along the frame 210 through the first mounting seat 140 or the second mounting seat 150 thereon, and the first mounting seat 140 and the second mounting seat 150 can ensure that the drainage baffle 120 moves stably on the frame 210. Specifically, the first mounting seat 140 and the second mounting seat 150 may each include a seat body and a roller 141, the roller 141 is rotatably mounted on the seat body, and the first mounting seat 140 and the second mounting seat 150 are movably arranged on the frame 210 of the filter press 200 through the roller 141. When the baffle assemblies are close to or separated from each other, each drainage baffle 120 can move along the frame 210 through the roller 141 thereon.

[0071] like Figure 1 As shown, in the above embodiment, an annular limiting groove can be set on the outer periphery of the roller 141 of the first mounting seat 140 and the second mounting seat 150, or one of the two, and the annular limiting groove is used to be clamped on the frame 210 of the filter press 200. It can be understood that the roller 141 can be clamped on the frame 210 through the annular limiting groove thereon and roll along the frame 210. The roller 141 can be limited to ensure that the roller 141 rolls along a specific route to avoid lateral shaking during the movement of the partition assembly. Among them, the first mounting seat 140 and the second mounting seat 150 can form a two-point support, so that the drainage partition 120 is in a vertical free state, and the drainage partitions 120 in the free state are squeezed by external pressure, thereby ensuring the uniformity of the filtration of each filter bag 110 and the consistent moisture content of the filter cake produced.

[0072] The filter press assembly 100 provided in the embodiment of the utility model includes a filter bag 110, a partition assembly, a driving mechanism 130 and a sealing assembly. The filter bag 110 is used to hold the filter material and has an opening at one end; the partition assembly includes at least two drainage partitions 120, each drainage partition 120 is arranged at intervals along a first direction X, and at least one filter bag 110 is arranged between two adjacent drainage partitions 120, wherein the first direction X is consistent with the thickness direction of the drainage partition 120; the driving mechanism 130 includes a linkage assembly 131 and a first driving unit 132, the linkage assembly 131 is connected between each drainage partition 120, the first driving unit 132 is connected to the partition assembly, and the first driving unit 132 is used to drive each drainage partition 120 to move closer to or away from each other, so as to filter the filter bag 110 through the drainage partition 120; the sealing assembly is used to seal or open the opening of the filter bag 110. When the filter press assembly 100 provided by the embodiment of the utility model is working, the partition assembly can be driven to approach each other by the first driving unit 132. Since the linkage assembly 131 is connected between the drainage partitions 120, driven by the linkage assembly 131, the drainage partitions 120 can maintain equal spacing during the movement, so that the pressure on each filter bag 110 is the same, thereby ensuring that the partition assembly can fully filter each filter bag 110, thereby improving the efficiency of the filter press. After the filter press is completed, the formed filter cake can be unloaded from the opening of the filter bag 110, and the operation is extremely convenient.

[0073] In addition, the embodiment of the utility model further provides a filter press 200, comprising a frame 210 and the filter press assembly 100 in the above embodiment, wherein the filter press assembly 100 is movably arranged on the frame 210. The filter press 200 can perform more efficient and thorough filter pressing of the filter to be filtered through the filter press assembly 100 therein, thereby improving the filter pressing quality and working efficiency of the filter press 200.

[0074] like Figure 4 As shown, in the above embodiment, the frame 210 may include two beams 211 arranged opposite to each other, the beams 211 extending along the first direction X, and the filter press assembly 100 is rolled on the beams 211 through the rollers 141 of the first mounting seat 140 and the second mounting seat 150. The two beams 211 may be parallel to each other, and the first mounting seat 140 and the second mounting seat 150 each move along one beam 211 to improve the overall structural stability of the filter press 200.

[0075] like Figure 4As shown, in the above embodiment, the filter press 200 may also include a pressure plate assembly 220 and a second driving unit 230, the pressure plate assembly 220 includes a first pressure plate 221 and a second pressure plate 222, the first pressure plate 221 and the second pressure plate 222 are respectively arranged on both sides of the partition assembly along the first direction X, the second driving unit 230 is connected to the first pressure plate 221, and the second driving unit 230 is used to drive the first pressure plate 221 to move along the first direction X to squeeze the partition assembly through the first pressure plate 221 and the second pressure plate 222. It can be understood that the second driving unit 230 can drive the first pressing plate 221 to move along the first direction X, and the first pressing plate 221 can squeeze the outermost drainage baffle 120 of the baffle assembly. At the same time, the outermost drainage baffle 120 of the baffle assembly is pressed against the second pressing plate 222. In this way, the baffle assembly can be squeezed by the first pressing plate 221 and the second pressing plate 222. By setting the first pressing plate 221 and the second pressing plate 222, the second driving unit 230 can be prevented from directly acting on the drainage baffle 120, thereby protecting the drainage baffle 120. In addition, by squeezing the drainage baffle 120 by the pressing plate, the force on the drainage baffle 120 can also be made more uniform, thereby improving the overall reliability of the filter press 200. Among them, the second pressing plate 222 can be fixedly arranged on the frame 210, and the second driving unit 230 can specifically use a hydraulic cylinder.

[0076] In the above embodiment, the projections of the first pressing plate 221 and the second pressing plate 222 along the first direction X can cover the projections of the drainage baffle 120 along the first direction X. In this way, the contact area between the pressing plate and the drainage baffle 120 can be increased, so that the pressure of the pressing plate on the drainage baffle 120 is more uniform, the load of the drainage baffle 120 is reduced, and the reliability of the press is further improved.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
