Detailed Implementation

[0045] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0046] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0047] The present disclosure will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0048] like Figures 1 to 5 As shown, this disclosure provides a filtration device 1, including a filter box 2 and a filter assembly. A slot structure is provided on the inner wall of the filter box 2, and the filter assembly is disposed inside the filter box 2.

[0049] like Figures 1 to 2 As shown, the filter assembly includes a filter screen 3 and an elastic structure. The elastic structure has a first end and a second end, the first end of which is connected to the filter screen 3, and the second end is inserted into a slot structure. The first and second ends of the elastic structure can undergo compressive deformation under external force, allowing the filter screen 3 to be detachably connected to the filter box 2.

[0050] Specifically, when the elastic structure is in its natural state, that is, when it is not subjected to external force, the length of the filter assembly in the direction from the first end to the second end of the elastic structure is greater than the length of the filter box 2 in the same direction. During the installation of the filter screen 3 into the filter box 2, an external force is applied to the elastic structure to cause it to compress and deform, thereby reducing the length of the filter assembly in the direction from the first end to the second end of the elastic structure, thus facilitating the placement of the filter assembly into the filter box 2. When the elastic structure in the filter assembly moves to face the slot structure on the inner wall of the filter box 2, the external force applied to the first and second ends of the elastic structure disappears, the elastic structure recovers its deformation, and is at least partially inserted into the slot structure, thereby allowing the filter assembly to be stably installed in the filter box 2. The filter screen 3 in the filter assembly can be used to filter the filter media entering the filter box 2 to filter out impurities in the filter media, thereby improving the quality of the filter media. When the elastic structure is at least partially inserted into the slot structure, an external force is applied to the elastic structure again to compress and deform it, causing it to withdraw from the slot structure, thereby separating the filter assembly from the filter box 2. This disclosure controls the engagement and disengagement between the elastic structure and the filter box 2 by controlling the compression deformation of the elastic structure, thus achieving a detachable connection between the filter assembly and the filter box 2, that is, a detachable connection between the filter screen 3 and the filter box 2, thereby improving the applicability of the filter device 1 during use.

[0051] like Figure 3 As shown in this embodiment, the filter box 2 has an opening, and the filter medium enters the filter box 2 through the opening. The filtration device 1 may include a cover plate 21, which is fixed at the opening to seal the filter box 2. It should be noted that the cover plate 21 and the filter box 2 can be fixed together by bolts.

[0052] A feed pipe 22 is provided on the cover plate 21, which communicates with the interior of the filter box 2, allowing the filter medium to enter the filter box 2 through the feed pipe 22. A flange 24 can be provided at the end of the feed pipe 22 away from the filter box 2 to facilitate the fixed connection of the feed pipe 22 with other external structures. A discharge pipe 23 is provided at the end of the side wall of the filter box 2 away from the opening, which communicates with the interior of the filter box 2, allowing the filter medium filtered by the filter screen 3 to exit from the filter box 2 through the discharge pipe 23.

[0053] It should be noted that the filter medium in this disclosure can be a copper sulfate solution, which filters out impurities such as copper shavings and copper powder from the copper sulfate solution through the filter screen 3. In this case, the flange 24 on the feed pipe 22 can be connected to the copper dissolving tank. However, it is not limited to this, and the filter medium can also be other media besides copper sulfate solution, depending on the actual situation.

[0054] In this embodiment, the filter assembly may include a fixing frame 5. A receiving cavity 51 is formed in the middle region of the fixing frame 5, and the filter screen 3 is installed within the receiving cavity 51. A receiving groove is formed in the edge region of the fixing frame 5, and the first end of the elastic structure is located within and connected to the receiving groove. By setting the fixing frame 5 and placing the filter screen 3 and the elastic structure on the fixing frame 5, the filter screen 3 can be fixedly installed in the filter box 2 when the elastic structure is inserted into the slot structure, and the filter screen 3 can be separated from the filter box 2 when the elastic structure is separated from the slot structure. That is, this application can achieve a detachable connection between the filter screen 3 and the filter box 2 by controlling the connection relationship (insertion or separation) between the elastic structure and the slot structure.

[0055] Furthermore, the receiving groove may include a bottom wall 521 and a first groove sidewall 522 and a second groove sidewall 523 formed on opposite sides of the bottom wall 521. The first groove sidewall 522 is disposed closer to the receiving cavity than the second groove sidewall 523. The second groove sidewall 523 has a through hole 524 extending through its inner and outer surfaces. The through hole 524 communicates with the interior of the receiving groove and corresponds to the slot structure.

[0056] The elastic structure may include a connector 41 and an elastic element 42. One end of the connector 41 is connected to the elastic element 42, and the other end passes through the through hole 524 and is inserted into the slot structure, thereby connecting the filter screen 3 and the filter box 2. The elastic element 42 is located at least within the receiving groove, and the end of the elastic element 42 away from the connector 41 is connected to the first groove sidewall 522 of the receiving groove. The elastic element 42 can undergo compressive deformation under external force to drive the connector 41 into the slot structure or to separate the connector 41 from the slot structure.

[0057] In this disclosure, the elastic element 42 can be a spring, but is not limited to it. The elastic element 42 can also be other structures with elastic contraction capabilities besides springs, depending on the actual situation.

[0058] In this embodiment of the present disclosure, the outer surface of the second tank sidewall 523 is sealed to the inner sidewall of the filter box 2, thereby avoiding the formation of gaps between the outer surface of the second tank sidewall 523 and the inner sidewall of the filter box 2, which would prevent some impurities in the filter medium from being filtered by the filter screen 3.

[0059] Furthermore, this disclosure allows the outer wall of the fixed frame 5 to fit against the inner wall of the filter box 2, thereby dividing the filter box 2 into an inlet area and an outlet area. The inlet area is located at the end of the outlet area closest to the opening. When the filter medium in the inlet area moves to the fixed frame 5, the filter medium can only pass through the filter screen 3 before entering the outlet area. This prevents impurities in the filter medium from entering the outlet area through the gap between the fixed frame 5 and the filter box 2, thereby reducing or preventing impurities from appearing in the filter medium and improving the quality of the filter medium.

[0060] For example, the filter box 2 in this disclosure can be a rectangular frame. In this case, the fixing frame 5 set in the filter box 2 can also be a rectangular frame. When the filter assembly is installed in the filter box 2, the outer side wall of the fixing frame 5 is completely fitted with the inner side wall of the filter box 2 to prevent the filter medium from entering the discharge area directly through the gap between the fixing frame 5 and the filter box 2 without being filtered. This can reduce impurities in the filter medium and improve the quality of the filter medium.

[0061] Furthermore, the elastic structure may also include a first limiting member 43 located within the receiving groove. An elastic member 42 is connected between the first limiting member 43 and the first groove sidewall 522. A plug-in member 41 is connected to the first limiting member 43 and located on the side of the limiting member away from the first groove sidewall 522. The orthographic projection of the first limiting member 43 on the second groove sidewall 523 covers the through hole 524. When the plug-in member 41 is engaged with the slot structure, the first limiting member 43 abuts against the second groove sidewall 523, thereby preventing the plug-in member 41 from completely detaching from the receiving groove. At the same time, since the first limiting member 43 can restrict the plug-in member 41 from completely detaching from the receiving groove, this disclosure can select an elastic member 42 with greater elastic expansion strength. That is, by setting the first limiting member 43, the selection of the elastic member 42 in this application can be more flexible.

[0062] In this embodiment, the elastic structure may include a pusher 44, one end of which is fixedly connected to the end of the elastic member 42 near the insertion member 41, and the other end of which extends outside the receiving groove. This disclosure allows the pusher 44 to move between the first and second ends to cause the elastic member 42 to undergo compressive deformation.

[0063] Specifically, the pusher 44 has a connecting portion 441 and a bent portion 442 inclined relative to the connecting portion 441. One end of the connecting portion 441 is fixedly connected to the end of the elastic member 42 near the insertion member 41, and the other end of the connecting portion 441 extends outside the receiving groove and connects to the bent portion 442 outside the receiving groove. This disclosure allows control of the detachable connection between the filter screen 3 and the filter box 2 by controlling the movement of the pusher 44 between the first end and the second end to cause the elastic member 42 to undergo compression deformation.

[0064] For example, the pusher 44 in this disclosure can be inverted L-shaped, with the bent portion 442 located outside the receiving groove and perpendicular to the connecting portion 441. This disclosure can push the bent portion 442 located outside the receiving groove to cause the elastic member 42 to undergo compression deformation between the first end and the second end, thereby realizing a detachable connection between the elastic structure and the slot structure, that is, realizing a detachable connection between the filter assembly and the filter box 2.

[0065] However, it is not limited to this. The pusher 44 in this disclosure can also be in other shapes besides the inverted L-shape, such as the T-shape, the inverted J-shape, etc., so that by controlling the movement of the pusher 44 between the first end and the second end, the elastic member 42 can be compressed and deformed, thereby realizing the detachable connection between the elastic structure and the slot structure.

[0066] It should be noted that when the elastic structure in this disclosure has both a first limiting member 43 and a pushing member 44, the connecting part 441 in the pushing member 44 can be connected to the first limiting member 43. The pushing member 44 pushes the first limiting member 43 to move between the first end and the second end, so that the elastic member 42 undergoes compression deformation. At the same time, the first limiting member 43 can abut against the side wall of the receiving groove near the receiving groove to limit the distance the elastic member 42 moves away from the first end, thereby preventing the insertion member 41 from disengaging from the receiving groove.

[0067] In this embodiment, the fixing frame 5 may include a second limiting member 53. The second limiting member 53 is located on the side of the receiving groove away from the bottom wall 521 of the groove, and the second limiting member 53 is connected to the inner surface of the first groove side wall 522. The second limiting member 53 is spaced apart from the elastic member 42, and the orthographic projection of the second limiting member 53 on the bottom wall 521 of the groove partially coincides with the orthographic projection of the elastic member 42 on the bottom wall 521 of the groove. That is, the second limiting member 53 in this disclosure can partially cover the opening of the receiving groove to avoid the problem that part of the elastic member 42 will detach from the receiving groove due to the groove opening being too large, thereby reducing the risk of damage to the elastic member 42, extending the service life of the elastic structure, and effectively ensuring the detachable connection between the filter screen 3 and the filter box 2.

[0068] Furthermore, the receiving groove may also include two intermediate groove sidewalls disposed between the first groove sidewall 522 and the second groove sidewall 523, with the elastic structure placed within the space formed by the two intermediate groove sidewalls, the first groove sidewall 522, the second groove sidewall 523, and the groove bottom wall 521. The two intermediate groove sidewalls are provided with sliding grooves 525, which are located at least between the second limiting member 53 and the second groove sidewall 523, and extend along the compression direction of the elastic structure. In this disclosure, by making the pushing member 44 slidably connected to the sliding groove 525, the friction between the pushing member 44 and the intermediate groove sidewall can be reduced. This reduces the risk of damage to the pushing member 44 and the fixing frame 5, while also facilitating control of the movement of the pushing member 44 between the first and second ends.

[0069] like Figure 4 As shown in the present embodiment, the elastic structure may include a plurality of elastic elements 42 arranged in an array at intervals, and the plurality of elastic elements 42 are connected to the side of the plug 41 near the first groove sidewall 522.

[0070] Furthermore, the filter assembly in this disclosure may include two elastic structures, which are disposed on opposite sides of the filter screen 3 and symmetrically arranged about the filter screen 3. The filter box 2 has slot structures on its two inner sidewalls corresponding to the two elastic structures, with a one-to-one correspondence between the slot structures and the elastic structures.

[0071] Each elastic structure may be provided with multiple elastic elements 42, and the multiple elastic elements 42 may be arranged in an array at intervals along the extension direction of the corresponding side of the filter screen 3.

[0072] For example, the number of elastic elements 42 in each elastic structure can be 4, 5, 6, etc., which can be set according to the actual situation.

[0073] This disclosure provides a plurality of elastic elements 42 arranged in an array at intervals in an elastic structure. When subjected to external force, the external force is uniformly transmitted to the plug-in 41 through the plurality of elastic elements 42, so that the plug-in 41 is uniformly stressed at all points and moves in a direction parallel to the first end to the second end. This avoids the plug-in 41 from deviating in the direction of movement and abutting against the inner sidewall of the receiving groove, thereby ensuring that the plug-in 41 can smoothly engage and disengage with the slot structure, thus ensuring the detachable connection between the filter screen 3 and the filter box 2.

[0074] like Figure 5As shown in this embodiment, the filter device 1 may further include a cleaning structure, which may specifically include a cleaning assembly 64, a sliding rod 61, a drive motor 62, and a guide rod 63. The cleaning assembly 64 is located inside the filter box 2 and contacts the filter surface of the filter screen 3 for cleaning the filter screen 3. The sliding rod 61 is located inside the filter box 2, and its opposite ends are respectively connected to the inner sidewall of the filter box 2. The sliding rod 61 is connected to the cleaning assembly 64 and can rotate around its central axis. The drive motor 62 is located outside the filter box 2, and its output end is fixedly connected to the sliding rod 61. Simultaneously, a mounting plate 25 may be provided on the outer sidewall of the filter box 2, with one end connected to the filter box 2 and the other end extending away from the filter box 2. The drive motor 62 is placed on the mounting plate 25 to provide support and protection for the drive electrode. The opposite ends of the guide rod 63 are respectively connected to the inner sidewall of the filter box 2. The guide rod 63 is used to guide the cleaning assembly 64 to prevent the cleaning assembly 64 from rotating with the sliding rod 61 when it slides along the axis of the sliding rod 61, thereby improving the stability of the cleaning assembly 64 during movement and ensuring that the cleaning assembly 64 can continuously clean the filter surface during movement.

[0075] It should be noted that the filter surface of filter screen 3 refers to the surface of filter screen 3 used for filtering the filter medium. The drive motor 62 can supply power to the sliding rod 61, causing the sliding rod 61 to rotate along its central axis, thereby driving the cleaning component 64 to slide on the sliding rod 61. By causing the cleaning component 64 to slide back and forth on the sliding rod 61, the filter screen 3 is cleaned reciprocally. The cleaning area of ​​the cleaning component 64 covers the filter surface of the filter screen 3, so as to avoid the accumulation of impurities on the filter screen 3 and the problem of filter screen 3 clogging. This can improve the filtration efficiency of the filter screen 3 for the filter medium, and improve the working efficiency and stability of the filter device 1 during use.

[0076] In this disclosure, the length of the cleaning component 64 can be the same as the length of the filter 3, and the width of the cleaning component 64 can be less than the width of the filter 3. The sliding direction of the cleaning component 64 is its width direction, and the length direction of the cleaning component 64 is perpendicular to its width direction.

[0077] Furthermore, the cleaning assembly 64 in this disclosure may include a base 641 and a cleaning component 642, with the base 641 connected to a sliding rod 61. Specifically, the sliding rod 61 may pass through the base 641, and a thread may be provided on the side of the sliding rod 61. When the drive motor 62 drives the sliding rod 61 to rotate, the thread of the sliding rod 61 can rotate and push the base 641 to reciprocate on the sliding rod 61. The cleaning component 642 is located between the base 641 and the filter screen 3, with one end of the cleaning component 642 located on the base 641 and the other end in contact with the filter surface of the filter screen 3. When the base 641 slides along the sliding rod 61, the cleaning component 642 cleans the filter screen 3 to prevent impurities from accumulating on the filter screen 3 and causing clogging, thereby improving the filtration efficiency of the filter screen 3 for the filter medium.

[0078] For example, the cleaning element 642 in this disclosure can be a brush bristle, and correspondingly, the base 641 can be a brush holder, but it is not limited to this. Other structures that can achieve cleaning of the filter screen 3 besides the brush bristle can be included in the embodiments of this disclosure.
