Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a filter press. Background Technology

[0002] In wastewater treatment, filter presses are typically used to separate solid sludge from liquid in the wastewater. During operation, the solid sludge is blocked by the filter cloth and gradually accumulates on it, forming a filter cake, while the liquid portion permeates through the filter cloth and flows away. Because the filter cake contains a small amount of moisture, some of it adheres to the filter cloth. To remove the filter cake from the filter press, external force must be applied to it for it to be removed effectively.

[0003] In the prior art, a vibration mechanism is installed on the filter press to apply vibration to the filter press, and the mechanical force generated by the vibration is used to remove the filter cake on the filter cloth.

[0017] The beneficial effects of this utility model are:

[0018] This invention provides a filter press, which comprises a first support and a second support arranged at intervals along a first direction, and multiple filter plate assemblies with filter chambers arranged between the first and second supports along the first direction. Filter elements are installed in the filter chambers along a second direction, and an inlet pipe is provided along the first direction connecting the filter chambers. This allows the liquid to be filtered to flow into the filter chambers of the filter plate assemblies after entering the inlet pipe. Solid sludge is blocked by the filter elements in the filter chambers, while the liquid can pass through the filter elements and enter the filter chambers of the next filter plate assembly. After being filtered by the filter elements in the filter chambers of multiple filter plate assemblies, the solid sludge in the liquid to be filtered is removed, thus achieving the filtration effect. Additionally, a vibrating assembly is provided on the main support. This vibrating assembly includes a magnetic memory alloy driving component and an actuating component arranged along the first direction. The magnetic memory alloy driving component can drive the actuating component to move along the first direction, thereby impacting the main support. This allows the magnetic memory alloy drive assembly to be used to remove filter cake from the filter media after filtration. The drive assembly impacts the main support, causing it to vibrate. This vibration is then transmitted to the multiple filter plate assemblies on the main support. The vibration of the filter plate assemblies also affects the filter media within their chambers, causing the solid sludge (filter cake) to detach under the mechanical force of the vibration, thus removing the filter cake from the filter chamber. In this process of removing filter cake, the magnetic memory alloy drive assembly serves as the power source for the impact. Because the drive assembly utilizes a magnetic field and the material properties of the magnetic memory alloy (deformation under a magnetic field) to generate power, its structure and principle are simple. It can operate without complex mechanical transmission structures, facilitating the installation, use, maintenance, and repair of the vibration mechanism. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0028] like Figure 1 As shown, this embodiment provides a filter press, which includes a main support 1, multiple filter plate assemblies 2, filter elements 3, liquid inlet pipe 4, and vibration assembly 5.

[0029] The aforementioned main support 1 includes a first support 11 and a second support 12 arranged at intervals along a first direction X1, where the first direction X1 is, for example, a horizontal direction. The first support 11 is, for example, a support formed by welding together multiple plate-like structures and multiple rod-like structures or by bolting them together, and the second support 12 is similarly formed. The function of the first support 11 and the second support 12 is to support other components in the filter press, providing a supporting function. Those skilled in the art can make specific settings according to the weight of each component and the installation position in the actual use scenario, which will not be described in detail here.

[0030] The aforementioned plurality of filter plate assemblies 2 are arranged along a first direction X1 between the first support 11 and the second support 12. Each filter plate assembly 2 is provided with a filter chamber 23, which extends along a second direction X2. Here, the second direction X2 is arranged at an angle to the first direction X1, for example, 90°.

[0031] For example, the filter plate assembly 2 includes a first filter plate 21 and a second filter plate 22 arranged along a first direction X1. A first groove 211 is formed on the side of the first filter plate 21 facing the second filter plate 22, and the first groove 211 extends along a second direction X2. That is, with... Figure 1 Taking the shown perspective as an example, a first groove 211 is formed on the right side of the first filter plate 21, and the first groove 211 extends from top to bottom. The first groove 211 is, for example, a rectangular groove. A second groove 221 is formed on the side of the second filter plate 22 facing the first filter plate 21, and the second groove 221 extends along a second direction X2, that is, with... Figure 1Taking the shown perspective as an example, a second groove 221 is provided on the left side of the second filter plate 22, and the second groove 221 extends from top to bottom. The shape and size of the second groove 221 should be adapted to the first groove 211, and the second groove 221 is also a rectangular groove, for example. The first groove 211 and the second groove 221 together form the filter chamber 23. In other words, after the right side of the first filter plate 21 is fitted and clamped to the left side of the second filter plate 22, the first groove 211 on the right side of the first filter plate 21 and the second groove 221 on the left side of the second filter plate 22 are directly opposite each other, so that the openings of the first groove 211 and the second groove 221 are connected to form a complete receiving cavity, which is the filter chamber 23.

[0032] The filter element 3 is installed inside the filter chamber 23 along the second direction X2. The filter element 3 is, for example, a filter cloth. Specifically, the filter element 3 is installed between the first filter plate 21 and the second filter plate 22. In other words, the filter element 3 is located between the first filter plate 21 and the second filter plate 22, and is fixed in place by the clamping force between the first filter plate 21 and the second filter plate 22.

[0033] The aforementioned inlet pipe 4 passes through the main support 1 along the first direction X1 and communicates with the filter chamber 23 in the filter plate assembly 2. It is readily understood that the inlet pipe 4 can pass through only the second support 12, only the first support 11, or both the first and second supports 12 simultaneously. When the inlet pipe 4 passes through only one support (i.e., only the first support 11 or only the second support 12), the end of the inlet pipe 4 can be fixedly welded (e.g., welded) to the inner wall of the support, thus sealing the inlet pipe 4 with the inner wall of the support. When the inlet pipe 4 passes through two supports simultaneously, a separate sealing element can be provided at the end of the inlet pipe 4 to prevent leakage of the liquid to be filtered inside the inlet pipe 4.

[0034] The aforementioned vibration assembly 5 is disposed on the aforementioned main support 1. It is readily understood that the vibration assembly 5 can be disposed on the outer side wall of the first support 11, the outer side wall of the second support 12, or both. The vibration assembly 5 includes a magnetic memory alloy driving component 51 arranged along the first direction X1 and an actuating component 52. The actuating component 52 is connected to the magnetic memory alloy driving component 51, which drives the actuating component 52 to move along the first direction X1, thereby impacting the aforementioned main support 1.

[0035] Therefore, the filter press provided in this embodiment includes a first support 11 and a second support 12 arranged at intervals along a first direction X1, and multiple filter plate assemblies 2 with filter chambers 23 arranged between the first support 11 and the second support 12 along the first direction X1. Filter elements 3 are installed in the filter chambers 23 along a second direction X2, and an inlet pipe 4 is provided along the first direction X1 connecting the filter chambers 23. This ensures that when the liquid to be filtered enters the inlet pipe 4, it flows into the filter chambers 23 of the filter plate assembly 2. Solid sludge is blocked by the filter elements 3 in the filter chambers 23, while the liquid can pass through the filter elements 3 and enter the filter chambers 23 of the next filter plate assembly 2. After being filtered by the filter elements 3 in the filter chambers 23 of multiple filter plate assemblies 2, the solid sludge in the liquid to be filtered is filtered out, thereby achieving the filtration effect of the liquid to be filtered. In addition, a vibration assembly 5 is provided on the main support 1. The vibration assembly 5 includes a magnetic memory alloy drive assembly 51 and an actuating element 52 arranged along the first direction X1. The magnetic memory alloy drive assembly 51 can drive the actuating element 52 to move along the first direction X1, thereby impacting the main support 1. In this way, when the filter cake on the filter element 3 of the filter press needs to be removed after the filtration work is completed, the magnetic memory alloy drive assembly 51 can drive the actuating element 52 to impact the main support 1. After the impact, the main support 1 vibrates, and the vibration is further transmitted to the multiple filter plate assemblies 2 on the main support 1. After the filter plate assembly 2 vibrates, the filter element 3 in the filter chamber 23 of the filter plate assembly 2 will also be affected by the vibration. The solid sludge (filter cake) generated during the filtration process attached to the filter element 3 will fall off under the influence of the mechanical force generated by the vibration, thereby realizing the removal of the filter cake in the filter chamber 23 of the filter press. In the process of removing the filter cake in the filter chamber 23 of the filter machine, the magnetic memory alloy drive component 51 is used as the power source for impact. Since the magnetic memory alloy drive component 51 uses the magnetic field and the material properties of the magnetic memory alloy (deformation will occur under the action of the magnetic field) to generate power, the structure and principle are simple. It can operate without setting up a complex mechanical transmission structure, which is convenient for the installation, use and maintenance of the vibration mechanism.

[0036] In some embodiments, such as Figure 2 As shown, the magnetic memory alloy drive assembly 51 includes: a housing 511, a magnetic core 512, an electromagnetic coil 513, a magnetic memory alloy component 514, an output component 515, and an elastic component 516.

[0037] The aforementioned housing 511 is, for example, a cylindrical shell 511, which is mounted on the outer wall of the aforementioned main support 1. The aforementioned magnetic core 512 is, for example, an iron core formed by stacking multiple silicon steel sheets or a soft magnetic alloy, and is disposed inside the housing 511. The aforementioned electromagnetic coil 513 is, for example, a coil wound with enameled wire, and is wound around the outer peripheral wall of the aforementioned magnetic core 512. The aforementioned magnetically controlled shape memory alloy 514 (MSMA) is, for example, made of a Ni-Mn-Ga ternary alloy (Ni2MnGa), or it can be made of a Co-Ni alloy (Ni content approximately 30%~35%), or it can be made of a NiMnIn-based alloy. The magnetic shape memory alloy 514 passes through the aforementioned magnetic core 512 along the first direction X1. It is easy to understand that a power supply is also connected to the aforementioned electromagnetic coil 513.

[0038] The output component 515 is arranged along the first direction X1. One end of the output component 515 is connected to the magnetic memory alloy component 514, and the other end is connected to the actuator 52. The output component 515 can transmit the displacement generated by the magnetic memory alloy component 514 to the actuator 52, thereby enabling the actuator 52 to impact the main support 1.

[0039] The aforementioned elastic element 516 is disposed between the magnetic memory alloy component 514 and the output component 515. This elastic element 516 can reset the magnetic memory alloy component 514.

[0040] With the above settings, when the electromagnetic coil 513 wound around the outside of the magnetic core 512 is energized, according to Ampere's circuital law, the current in the coil will generate a closed magnetic circuit. Since the magnetic permeability of the magnetic core 512 is much higher than that of air, the magnetic lines of force can be highly concentrated in the region where the magnetic memory alloy 514 is located. At this time, the magnetic memory alloy 514 is affected by the magnetic field. Under the influence of the twin reorientation mechanism driven by magnetocrystalline anisotropy, the magnetic memory alloy 514 will deform. Specifically, when the direction of the applied magnetic field is perpendicular to the transverse direction of the easy magnetization axis of the magnetic memory alloy 514, the magnetic domain deflection induces twin boundary slip, which is macroscopically manifested as elongation along the direction perpendicular to the magnetic field (that is, the length of the magnetic memory alloy 514 in the first direction X1 increases). When the length of the magnetic memory alloy component 514 increases in the first direction X1, it pushes the connected actuator 52 to move along the first direction X1, causing the actuator 52 to impact the main support 1. Simultaneously, it compresses the elastic element 516 located between the magnetic memory alloy component 514 and the output component 515. When the power supply to the electromagnetic coil 513 is disconnected, the magnetic field acting on the magnetic memory alloy component 514 disappears. The magnetic memory alloy component 514 will no longer deform and will recover under external force. At this time, the compressed elastic element 516 recovers, thus pushing the magnetic memory alloy component 514 to move away from the main support 1 until the magnetic memory alloy component 514 returns to its original length for the next action. The structure is simple, without additional transmission structures, and easy to use. Furthermore, during the process of the elastic element 516 pushing the magnetic memory alloy component 514 to return to its original length, the magnetization intensity inside the magnetic memory alloy component 514 changes due to the rebound of the twinned structure, causing a change in the magnetic flux passing through the electromagnetic coil 513. According to Faraday's law of electromagnetic induction, a change in magnetic flux will induce a current in the electromagnetic coil 513, and the direction of the induced current is determined by Lenz's law. Furthermore, the induced current generated in the electromagnetic coil 513 can be stored in a supercapacitor for use in other control circuits, thus achieving energy recovery and saving energy to a certain extent, reducing the operating cost of the filter press.

[0041] In some embodiments, such as Figure 2 As shown, the magnetic memory alloy drive assembly 51 further includes a fixing member 517, which is, for example, plate-shaped and disposed inside the housing 511. The output member 515 passes through the fixing member 517.

[0042] The aforementioned output component 515 includes an output end 5151 and a connecting end 5152. The connecting end 5152 abuts against the end of the magnetic memory alloy component 514 near the main support 1 (i.e., they are in contact), while the output end 5151 is connected to the actuating component 52. The right end of the output component 515 is the output end 5151, and the left end is the connecting end 5152. The connecting end 5152 is connected to the right end of the magnetic memory alloy component 514, and the output end 5151 is connected to the actuating component 52. In the second direction X2, the size of the connecting end 5152 of the output component 515 is larger than the size of the output end 5151. In other words, the cross-sectional shape of the output component 515 is a "T" shape, with the larger end of the "T" shape being the connecting end 5152 and the smaller end being the output end 5151. This cross-sectional direction is parallel to the axial direction of the output component 515.

[0043] The aforementioned elastic element 516 is sleeved on the output element 515 and is located between the fixing element 517 and the connecting end 5152 of the output element 515. The elastic element 516 is, for example, a compression spring or a spring sheet.

[0044] With the above configuration, when the magnetic memory alloy component 514 deforms under the action of a magnetic field, pushing the output rod to move along the first direction X1, and thus driving the actuator 52 to move along the first direction X1 and impact the main support 1, one end of the elastic component 516 abuts against the fixed component 517, and the other end abuts against the connecting end 5152 of the output component 515. When the output component 515 moves towards the main support 1, it will compress the elastic component 516, causing the elastic component 516 to accumulate elastic potential energy. When applied to the magnetic memory alloy component 514... After the magnetic field on 4 disappears, the magnetic memory alloy component 514 stops pushing against the output component 515. At the same time, the elastic component 516 releases its accumulated elastic potential energy, that is, it pushes against the connecting end 5152 of the output component 515 in a direction away from the main support 1, and then pushes against the magnetic memory alloy component 514, so that the magnetic memory alloy component 514 is subjected to external force. Under the action of external force, the magnetic memory alloy component 514 recovers its original length in the first direction X1. The structure is simple, easy to use, and easy to install and maintain.

[0045] In some embodiments, such as Figure 2 As shown, the aforementioned actuator 52 includes a connecting portion 521 and an actuating portion 522 arranged along the first direction X1. The connecting portion 521 is threadedly connected to the output end 5151. The actuating portion 522 is used to impact the main body bracket 1. This arrangement facilitates the connection and disassembly of the actuator 52 and the output portion 515, thereby facilitating the replacement and maintenance of the actuator 52.

[0046] In some embodiments, such as Figure 1As shown, there can be multiple vibrating components 5, which are respectively disposed on the first support 11 and the second support 12. For example, there are four vibrating components 5, with two disposed on the first support 11 and the other two disposed on the second support 12. Distributing multiple vibrating components 5 on the first support 11 and the second support 12 improves the removal effect of filter cake inside the filter press.

[0047] In some embodiments, such as Figure 1 As shown, in the first direction X1, multiple vibrating components 5 located on the first support 11 are correspondingly arranged with multiple vibrating components 5 located on the second support 12. For example, two vibrating components 5 are installed on the first support 11, and two vibrating components 5 are also installed on the second support 12. In the first direction X1, the two vibrating components 5 installed on the first support 11 and the two vibrating components 5 installed on the second support 12 are correspondingly arranged. By this arrangement, the position of vibration on the first support 11 corresponds to the position of vibration on the second support 12, ensuring that the vibration on the two supports tends to be balanced, thereby ensuring the stability of the entire filter press during operation.

[0048] In some embodiments, such as Figure 1 As shown, the number of vibrating components 5 on the first support 11 is even (for example, 2), and the multiple vibrating components 5 on the first support 11 are symmetrically arranged on the first support 11 with the axis of the liquid inlet pipe 4 as the axis of symmetry. And / or, the number of vibrating components 5 on the second support 12 is even (for example, 2), and the multiple vibrating components 5 on the second support 12 are symmetrically arranged on the second support 12 with the axis of the liquid inlet pipe 4 as the axis of symmetry. This arrangement ensures that, in the second direction X2, the vibration position of the upper half of the first support 11 corresponds to the vibration position of the lower half of the first support 11, ensuring a balance in the vibration areas of the upper and lower parts of the first support 11. Similarly, this arrangement also ensures that the vibration position of the upper half of the second support 12 corresponds to the vibration position of the lower half of the second support 12, ensuring a balance in the vibration areas of the upper and lower parts of the second support 12, thereby further guaranteeing the stability of the entire filter press during operation.

[0049] In some embodiments, such as Figure 1 As shown, the filter plate assembly 2 is provided with a filtrate outlet 24, which is connected to both the first groove 211 and the second groove 221. By providing the filtrate outlet 24 on the filter plate assembly 2, the filtered filtrate can be discharged from the filter chamber 23 of the filter plate assembly 2 in a timely manner, ensuring the filtration effect.

[0050] For example, such as Figure 1 As shown, the lower end of the first filter plate 21 is provided with a first liquid outlet channel 212, which communicates with the first groove 211 on the first filter plate 21. The lower end of the second filter plate 22 is provided with a second liquid outlet channel 222, which communicates with the first groove 211 on the second filter plate 22. The first liquid outlet channel 212 and the second liquid outlet channel 222 together form the filtrate outlet 24. With this arrangement, the filtered liquid can flow out from the first liquid outlet channel 212 and the second liquid outlet channel 222 respectively, forming a redundant multi-flow path configuration. When one liquid outlet channel (e.g., the first liquid outlet channel 212) cannot work properly due to blockage or other reasons, the other liquid outlet channel (i.e., the second liquid outlet channel 222) can still maintain the flow of liquid, reducing the risk of downtime maintenance of the filter press and improving the practicality of the filter press.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
