Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a filtration device for sludge dewatering in wastewater treatment plants. Background Technology

[0002] In the process of wastewater treatment, sludge dewatering is a crucial step, and its treatment effect and efficiency directly affect the operating cost and environmental benefits of wastewater treatment plants. Some manufacturers use plate and frame filter presses as mechanical dewatering equipment for sludge. This is a traditional filter press that squeezes water out of the sludge through the squeezing action of plates and frames. The filter cloth set on the plates and frames filters out the water, thus achieving the effect of sludge dewatering.

[0003] However, when using some plate and frame filter presses, the unloading process relies on manual opening of the plate and frame components one by one, which is labor-intensive and time-consuming. Furthermore, after dewatering, sludge easily adheres to the surface of the filter cloth, requiring mechanical cleaning with tools such as scrapers. This is not only inefficient but may also damage the filter cloth and increase equipment maintenance costs. Therefore, a filtration device for sludge dewatering in wastewater treatment plants is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-6This utility model provides a filtration device for sludge dewatering in a wastewater treatment plant, including a support frame 1; a connecting frame 4 is fixedly connected to the side wall of the support frame 1, an extruder 2 is installed on the top of the support frame 1, a filter plate 3 is slidably connected to the side wall of the connecting frame 4, a sliding frame 5 is slidably connected to the other side wall of the connecting frame 4, a slider 57 is slidably connected to the middle of the sliding frame 5, a rectangular shell 51 is fixedly connected to the end of the slider 57, a cleaning component is provided in the middle of the rectangular shell 51, and an extrusion block 58 is fixedly connected to the bottom of the rectangular shell 51. The other end of the slider 57 is rotatably connected to a connecting plate 52. The bottom side wall of the connecting plate 52 is rotatably connected to a connecting block 54. A handle 53 is fixedly connected to the side wall of the connecting block 54. The cleaning assembly includes a mounting plate 561, which is slidably connected to the middle of the rectangular shell 51. The side wall of the mounting plate 561 contacts a scraper 56. During operation, after the sludge is dewatered by the squeezer 2 and the filter plate 3, the squeezer 2 can be activated to prevent it from contacting the filter plate 3. At this time, the slider can be pushed. Frame 5, the sliding frame 5 will slide on the side wall of the connecting frame 4. At the same time, the sliding frame 5 will drive the rectangular shell 51 and the extrusion block 58 to move synchronously until the extrusion block 58 is located at the top between the multiple sets of filter plates 3. At this time, the handle 53 can be pulled to drive the connecting block 54 to move. When the connecting block 54 moves, it will rotate with the connecting plate 52, and the angle of the connecting plate 52 will change. At this time, the other end of the connecting plate 52 will rotate with the slider 57, causing the slider 57 to slide in the middle of the sliding frame 5. The shell 51 and the extrusion block 58 will also move together and move towards the position between the multiple sets of filter plates 3 until the extrusion block 58 contacts the filter plates 3. The multiple sets of filter plates 3 will unfold along the inclined surface of the extrusion block 58, and the rectangular shell 51 and the extrusion block 58 will continue to move deeper between the multiple sets of filter plates 3. At this time, the scraper 56 in the cleaning component will contact the filter plates 3 and clean the sludge adhering to the side wall of the filter plates 3. In this way, while unfolding the filter plates 3, the sludge adhering to the filter plates 3 can be cleaned, which improves the processing efficiency.

[0027] Furthermore, such as Figures 5-6As shown, the cleaning assembly also includes a connector strip 563, which is fixedly connected to the side wall of the scraper 56. The mounting plate 561 has a connector groove 566 on its side wall, and the connector strip 563 is inserted into the middle of the connector groove 566. A limiting groove 565 is provided in the middle of the connector groove 566. A rubber strip 564 is fixedly connected to the side wall of the connector strip 563, and the rubber strip 564 contacts the middle of the limiting groove 565. During operation, when the scraper 56 needs to be disassembled and replaced after a period of use, the scraper 56 can be pulled directly, causing the connector strip 563 to move. The rubber strip 564 will slide in the middle of the insertion groove 566, and move the rubber strip 564. The rubber strip 564 will deform due to its own elasticity and detach from the middle of the limiting groove 565 until the insertion strip 563 is completely detached from the middle of the insertion groove 566. During installation, the insertion strip 563 is directly inserted into the middle of the insertion groove 566. During this process, the rubber strip 564 will deform elastically until the rubber strip 564 coincides with the limiting groove 565. At this time, the rubber strip 564 will reset due to its own elasticity and be stuck in the middle of the limiting groove 565. The whole process is quick and convenient, improving the efficiency of maintaining the scraper 56.

[0028] Furthermore, such as Figures 2-4 As shown, an L-shaped baffle 55 is fixedly connected to the side wall of the end of the rectangular shell 51. A ball bearing 551 is rotatably connected to the side wall of the end of the L-shaped baffle 55. During operation, after the filter plate 3 is unfolded by the rectangular shell 51 and the extrusion block 58, the moving filter plate 3 will contact the L-shaped baffle 55. The L-shaped baffle 55 supports the moving filter plate 3, ensuring the cleaning effect of the scraper 56 on the side wall of the filter plate 3. The L-shaped baffle 55 will move with the rectangular shell 51, and the ball bearing 551 will roll on the side wall of the filter plate 3 to ensure the smooth movement of the L-shaped baffle 55.

[0029] Furthermore, such as Figure 3 and Figure 5 As shown, the slider 57 has a groove 571 on its side wall. A rotating rod 59 is rotatably connected to the middle of the groove 571. The end of the rotating rod 59 is fixed to the side wall of the connecting plate 52. A torsion spring 510 is sleeved on the outer wall of the rotating rod 59. One end of the torsion spring 510 is fixed to the side wall of the connecting plate 52, and the other end is fixed to the middle of the groove 571. During operation, when the connecting plate 52 and the slider 57 rotate, the connecting plate 52 will drive the rotating rod 59 to rotate in the middle of the groove 571, and drive the torsion spring 510 to undergo torsional deformation. When the handle 53 is not in use, the connecting plate 52 will reset under the elastic action of the torsion spring 510. The slider 57, the rectangular shell 51 and the cleaning assembly will also reset accordingly, improving convenience.

[0030] Furthermore, such as Figures 5-6As shown, the cleaning assembly also includes a spring 562. One end of the spring 562 is fixed to the middle of the rectangular shell 51, and the other end of the spring 562 is fixed to the side wall of the mounting plate 561. When working, the spring 562 has a certain elasticity. Through its own elasticity, it can ensure that the scraper 56 and the side wall of the filter plate 3 are tightly attached to each other, thus ensuring the effect of sludge cleaning.

[0031] Furthermore, such as Figure 6 As shown, the end of the rubber strip 564 is set with an arc-shaped surface. During operation, the arc-shaped surface ensures that the rubber strip 564 can smoothly detach from the middle of the limiting groove 565, thus improving convenience.

[0032] Furthermore, such as Figures 1-2 As shown, multiple sets of rectangular shell 51, connecting plate 52 and cleaning components are provided, and the multiple sets of rectangular shell 51, connecting plate 52 and cleaning components are symmetrically arranged with the center line of sliding frame 5 as the axis of symmetry. During operation, the multiple sets of rectangular shell 51, connecting plate 52 and cleaning components ensure that the sides of filter plate 3 can be thoroughly cleaned, thus improving practicality.

[0033] Working principle: After the sludge is dewatered by the press 2 and filter plate 3, the press 2 can be activated to prevent it from contacting the filter plate 3. At this time, the sliding frame 5 can be pushed, and the sliding frame 5 will slide on the side wall of the connecting frame 4. At the same time, the sliding frame 5 will drive the rectangular shell 51 and the pressing block 58 to move synchronously until the pressing block 58 is located at the top between the multiple sets of filter plates 3. Then, the handle 53 can be pulled to move the connecting block 54. When the connecting block 54 moves, it will rotate with the connecting plate 52, and the angle of the connecting plate 52 will change. At this time, the other end of the connecting plate 52 will be connected with the slider 57. The rotation causes the slider 57 to slide in the middle of the sliding frame 5. The rectangular shell 51 and the extrusion block 58 will also move accordingly and move towards the position between the multiple sets of filter plates 3 until the extrusion block 58 contacts the filter plates 3. The multiple sets of filter plates 3 will unfold along the inclined surface of the extrusion block 58, and the rectangular shell 51 and the extrusion block 58 will continue to move deeper between the multiple sets of filter plates 3. At this time, the scraper 56 in the cleaning component will contact the filter plates 3 and clean the sludge adhering to the side wall of the filter plates 3. In this way, while unfolding the filter plates 3, the sludge adhering to the filter plates 3 can be cleaned, which improves the processing efficiency.

[0034] After the filter plate 3 is unfolded by the rectangular shell 51 and the extrusion block 58, the moving filter plate 3 will come into contact with the L-shaped baffle 55. The L-shaped baffle 55 supports the moving filter plate 3, ensuring the cleaning effect of the scraper 56 on the side wall of the filter plate 3. The L-shaped baffle 55 will move with the rectangular shell 51, and the ball bearing 551 will roll on the side wall of the filter plate 3 to ensure the smooth movement of the L-shaped baffle 55.

[0035] When the scraper 56 needs to be disassembled and replaced after a period of use, it can be pulled directly. The scraper 56 will move the connector strip 563, which will slide in the middle of the connector groove 566, moving the rubber strip 564. The rubber strip 564 will deform due to its elasticity and detach from the middle of the limiting groove 565 until the connector strip 563 is completely detached from the middle of the connector groove 566. During installation, the connector strip 563 is directly inserted into the middle of the connector groove 566. During this process, the rubber strip 564 will deform elastically until it overlaps with the limiting groove 565. At this time, the rubber strip 564 will reset due to its elasticity and be stuck in the middle of the limiting groove 565. The whole process is quick and convenient, improving the efficiency of maintaining the scraper 56.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
