Description

Technical Field

[0001] This application relates to the field of filter press technology, and in particular to a filter press outlet pipe structure. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device.

[0003] The outlet of the filter press is usually connected to an outlet pipe, which leads into the clear liquid flow tank. Some outlet pipes are too long, and even extend directly into the clear liquid flow tank, making it difficult to observe the flowing liquid. In addition, the water pipe is easy to fall off and enter the subsequent tank, causing equipment and pipeline blockage, increasing the intensity of maintenance work, and hindering the subsequent work. Utility Model Content

[0004] The purpose of this application is to provide a filter press outlet pipe structure to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this application is as follows: A filter press outlet pipe structure, comprising: A water outlet section is provided at the water outlet, and a valve is provided on the water outlet section; The water tank is used to collect the water output from the filter press. A receiving plate, disposed on the upper edge of the water tank, is used to guide the water flow from the outlet section into the water tank.

[0006] Preferably, the receiving plate is provided with a flow guide groove.

[0007] Preferably, there are multiple guide channels, which are spaced apart along the width of the receiving plate, and each guide channel corresponds to one of the multiple outlet sections in the filter press.

[0008] Preferably, the guide channel is sealed at one end facing the outlet section and open at one end facing the water tank.

[0009] Preferably, the receiving plate has a sliding groove on its side wall along the width direction, a movable stud is slidably engaged in the sliding groove, a locking handle is rotatably sleeved on the movable stud, and a first locking nut for locking the locking handle is also provided on the movable stud; the end of the locking handle away from the movable stud is engaged with the water tank.

[0010] Preferably, the end of the snap-fit ​​handle away from the movable stud is provided with a snap-fit ​​groove, and the snap-fit ​​groove is snap-fitted into the side wall of the water tank.

[0011] Preferably, the snap-fit ​​handle is provided with a fixing stud, an auxiliary support rod is rotatably sleeved on the fixing stud, and a second locking nut for locking the auxiliary support rod is screwed on the fixing stud.

[0012] Preferably, the end of the auxiliary support rod away from the fixed stud is rotatably provided with a rotating roller for supporting the bottom of the receiving plate.

[0013] The filter press outlet pipe structure disclosed in this application significantly improves installation stability compared to the long outlet pipes in the prior art. The short-distance design of the outlet section completely solves the problem of easy detachment of long outlet pipes, thereby avoiding pipe and equipment blockage and reducing the workload of maintenance personnel.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0017] like Figure 1-6 As shown, a filter press 1 outlet pipe structure includes: A water outlet section 2 is installed at the water outlet, and a valve is provided on the water outlet section 2; Water tank 4 is used to receive the effluent from filter press 1; The receiving plate 3 is set on the upper edge of the water tank 4 and is used to guide the water flow from the outlet section 2 into the water tank 4.

[0018] The water outlet section 2 is directly installed at the water outlet of the filter press 1, replacing the excessively long water outlet pipe in the prior art. Its length is designed to be close to the water tank 4, without extending into the water tank 4. The sealing performance after installation is ensured by a sealing connection method that is compatible with the water outlet (such as threaded connection or flange connection) to avoid water leakage.

[0019] The valves configured on the outlet section 2 can control the flow of water at the corresponding outlet according to actual needs, which is convenient for individual maintenance of a single outlet and allows for flexible adjustment of the water flow rate.

[0020] Water tank 4 retains the original clear liquid receiving function of filter press 1, mainly used to collect the clear liquid after diversion. Its structure can be flexibly adjusted according to the on-site installation space without additional modification.

[0021] The receiving plate 3 is horizontally set at the upper edge of the water tank 4, and the height of its receiving surface is slightly lower than the water outlet end of the water outlet section 2, so that the liquid flowing out of the water outlet section 2 can fall accurately onto the receiving plate 3, and then flow smoothly into the water tank 4 through the guiding effect of the receiving plate 3.

[0022] Compared to the long outlet pipe in the background technology, the short-distance design of the outlet section 2 significantly improves installation stability and completely solves the problem of long outlet pipes being prone to falling off, thereby avoiding pipe and equipment blockage and reducing the workload of maintenance personnel. At the same time, the unobstructed layout between the receiving plate 3 and the outlet section 2 allows staff to directly observe the clarity, flow rate, and other status of the outflowing liquid, and promptly grasp the solid-liquid separation effect of the filter press 1, providing a guarantee for the smooth operation of subsequent work.

[0023] In some further embodiments, the receiving plate 3 is provided with a guide groove 30.

[0024] On the bearing surface of the receiving plate 3, the guide groove 30 is recessed along the direction of water flow, and its extension trajectory points from one end near the outlet section 2 to the inside of the water tank 4. The structure of the tank is adapted to the water flow path.

[0025] The flow channel 30 can optimize the flow state of water. In the background technology, if only the planar receiving plate 3 is relied upon, the water flow is easy to spread in all directions, and even splashing water may occur. However, the flow channel 30 can form a directional constraint on the water flow, guide the water flow to flow precisely along the channel, and prevent the water flow from overflowing the receiving plate 3 or spreading disorderly.

[0026] This design simultaneously improves the stability and concentration of water flow, reduces waste of clear liquid, and prevents splashing liquid from polluting the surrounding environment, keeping the area around the equipment clean. Furthermore, the cross-sectional shape of the guide channel 30 can be selected as U-shaped or V-shaped depending on the actual water flow velocity. The U-shaped channel is more suitable for high-flow-rate conditions, reducing water flow resistance, while the V-shaped channel can create a concentrated water flow even with lower flow rates, ensuring effective water flow guidance. The inner wall of the channel can be smoothed to further reduce water flow friction and improve water flow efficiency.

[0027] In some further embodiments, there are multiple guide channels 30, which are spaced apart along the width of the receiving plate 3, and each guide channel 30 corresponds to a multiple outlet section 2 in the filter press 1.

[0028] When the filter press 1 is equipped with multiple outlets, multiple outlet sections 2 will be installed accordingly. At this time, the number of guide grooves 30 on the receiving plate 3 is consistent with the number of outlet sections 2, and they are evenly distributed along the width of the receiving plate 3. The position of each guide groove 30 is precisely aligned with the outlet end of an outlet section 2. Adjacent guide grooves 30 are separated by a raised partition structure to avoid mutual interference of water flow in different guide grooves 30. This achieves independent guidance and zoned observation of multiple groups of water flow. Compared with a single guide groove 30 or a flat receiving plate 3, multiple one-to-one corresponding guide grooves 30 can keep the water flow of each outlet section 2 independent. The staff can observe the water flow status in each guide groove 30 separately. For example, if the water flow in a certain guide groove 30 becomes turbid, the corresponding outlet can be quickly located to determine whether there is a problem with the filter media in that area. There is no need to shut down the entire machine for inspection, which greatly improves the efficiency of troubleshooting and reduces the losses caused by equipment downtime.

[0029] In some further embodiments, the guide channel 30 is sealed at one end toward the outlet section 2 and open at the other end toward the water tank 4.

[0030] The end of the guide channel 30 facing the outlet section 2 is sealed by a closed structure. This closed structure is integrally formed with the receiving plate 3 or fixed by a seal to ensure that water cannot flow out from this end. The end facing the water tank 4 remains open, with the edge of the opening corresponding to the inlet area of ​​the water tank 4, so that water can flow directly into the water tank 4 from the open end.

[0031] The sealing end can effectively prevent water flow from spreading to the edge of the receiving plate 3, thus preventing water from overflowing from the side of the receiving plate 3. In some further embodiments, the receiving plate 3 has a sliding groove 31 on its side wall along the width direction. The sliding groove 31 is slidably engaged with a movable stud 5. A locking handle 6 is rotatably sleeved on the movable stud 5. The movable stud 5 is also provided with a first locking nut 50 for locking the locking handle 6. The end of the locking handle 6 away from the movable stud 5 is engaged with the water tank 4.

[0032] On both sides of the receiving plate 3 along the width direction, the sliding groove 31 is opened along the length direction of the side wall. The groove is a through structure. One end of the movable stud 5 is slidably embedded in the sliding groove 31 through the snap-fit ​​structure and can move freely along the length direction of the sliding groove 31. The other end of the movable stud 5 passes through one end of the snap-fit ​​handle 6. The snap-fit ​​handle 6 can rotate freely around the movable stud 5. The first locking nut 50 is screwed on the movable stud 5 and is located on the outside of the snap-fit ​​handle 6. After tightening, the rotation angle of the snap-fit ​​handle 6 can be fixed by friction. The other end of the snap-fit ​​handle 6 is detachably snapped to the edge or side wall of the water tank 4 through the matching snap-fit ​​structure.

[0033] Compared to traditional fixed connection methods, this application does not require destructive processing such as welding or drilling on the water tank 4 or the receiving plate 3. The installation and disassembly process is simple and quick. At the same time, by adjusting the position of the movable stud 5 through the sliding groove 31 and adjusting the rotation angle of the snap-fit ​​handle 6, it can be adapted to water tanks 4 of different sizes and water outlet sections 2 of different installation heights, which greatly improves the adaptability of the structure. The first locking nut 50 after locking can ensure the stability of the connection structure and prevent the receiving plate 3 from shifting during use.

[0034] The cross-section of the sliding groove 31 can be a T-shaped cross-section to show that the movable stud 5 can only slide along the length direction of the sliding groove 31.

[0035] In some further embodiments, the end of the snap-fit ​​handle 6 away from the movable stud 5 is provided with a snap-fit ​​groove 60, which is snap-fitted to the side wall of the water tank 4.

[0036] The end of the snap-fit ​​handle 6 away from the snap-fit ​​handle 6 has a snap-fit ​​groove 60 opened along the thickness direction of the snap-fit ​​handle 6. The width of the snap-fit ​​groove 60 is adapted to the thickness of the side wall of the water tank 4. When snapping, the snap-fit ​​groove 60 is aligned with the side wall of the water tank 4, and the inner wall of the snap-fit ​​groove 60 is tightly fitted with the side wall of the water tank 4 to achieve a stable snap-fit ​​between the snap-fit ​​handle 6 and the water tank 4.

[0037] In some further embodiments, the snap-fit ​​handle 6 is provided with a fixing stud 8, an auxiliary support rod 7 is rotatably sleeved on the fixing stud 8, and a second locking nut 80 for locking the auxiliary support rod 7 is screwed on the fixing stud 8.

[0038] The fixing stud 8 is vertically set in the middle area of ​​the snap-fit ​​handle 6 or near one end of the water tank 4, and is integrally formed with the snap-fit ​​handle 6. One end of the auxiliary support rod 7 is rotatably sleeved on the fixing stud 8, and can rotate freely around the fixing stud 8 to adjust the support angle. The second locking nut 80 is screwed on the fixing stud 8 and is located on the outside of the rotating sleeve. After tightening, it can fix the rotation angle of the auxiliary support rod 7 and ensure the stability of the support state.

[0039] When the length of the receiving plate 3 is long or the water flow impact force it bears is large, the connection of the clamping handle 6 and the first locking nut 50 alone may not be able to meet the support requirements. The auxiliary support rod 7 can provide upward support from the bottom of the receiving plate 3, effectively dispersing the force on the receiving plate 3, avoiding problems such as bending and deformation of the receiving plate 3 due to long-term stress, extending the service life of the receiving plate 3, and improving the overall stability of the entire pipeline structure.

[0040] The auxiliary support rod 7 is positioned with the end furthest from the fixing stud 8 facing the outlet section 2.

[0041] In some further embodiments, the end of the auxiliary support rod 7 away from the fixed stud 8 is rotatably provided with a rotating roller 70 for supporting the bottom of the receiving plate 3.

[0042] The end of the auxiliary support rod 7 away from the fixed stud 8 is rotatably connected to the rotating roller 70 through a rotating shaft. The axis of the rotating shaft is consistent with the axis of the rotating roller 70. The rotating roller 70 can rotate freely around the rotating shaft. The outer circumferential surface of the rotating roller 70 is made of a smooth and wear-resistant material. When the auxiliary support rod 7 supports the receiving plate 3, the outer circumferential surface of the rotating roller 70 is in close contact with the bottom of the receiving plate 3 to form rolling support.

[0043] When adjusting the position of the receiving plate 3, the rolling support of the rotating roller 70 can convert sliding friction into rolling friction, which greatly reduces frictional resistance. This not only makes it convenient for staff to adjust the position of the receiving plate 3, but also protects the bottom structure of the receiving plate 3 from scratches and damage.

[0044] Meanwhile, the rolling support method ensures that the auxiliary support rod 7 always maintains close contact with the bottom of the receiving plate 3, resulting in a stable and reliable support effect.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
