Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a novel plate and frame structure for a filter press. Background Technology

[0002] Wastewater treatment often generates large amounts of sludge with a water content as high as 95-99.5%. To facilitate transportation and subsequent disposal, dewatering is essential, typically achieved through mechanical dewatering via filter press. Existing plate and frame filter presses often suffer from inconvenient filter cloth fixing and tensioning, impacting work efficiency. Furthermore, over long-term use, uneven stress on the filter cloth can lead to tensile deformation. Severely deformed filter cloth cannot maintain its tension, thus affecting filtration efficiency. Existing plate and frame structures often require downtime for disassembly and replacement, resulting in low filter cloth utilization and resource waste. Therefore, we propose a novel plate and frame structure for filter presses. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new plate and frame structure for filter presses. By rotating the tightening rod, the filter cloth on both sides of the main plate can be quickly tightened and fixed, making filter cloth installation faster and improving work efficiency. This can effectively solve the problems in the background art.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a novel plate and frame structure for a filter press, including a main plate body 1. Guide holes 2 are provided at the four corners of the side surface of the main plate body 1 for movement on the guide rods of the filter press. Two sets of bearing seats 3 are symmetrically arranged on the four side surfaces of the main plate body 1, with each set including two bearing seats 3, i.e., four bearing seats 3 are provided on each of the four side surfaces of the main plate body. A tightening rod 4 for tightening the filter cloth is rotatably arranged between two opposing bearing seats 3. Two tightening rods 4 are provided on each of the four side surfaces of the main plate body, respectively tightening the two filter cloths on both sides of the main plate body 1. By rotating the tightening rods 4, the filter cloths on both sides of the main plate body 1 can be quickly tightened and fixed, making filter cloth installation faster and improving work efficiency. After the filter cloth has been stretched and deformed for a period of time, the tension and filtration effect can be maintained by rotating the tightening rods 4, greatly improving the utilization rate of the filter cloth, reducing waste of filter cloth resources, and lowering wastewater treatment costs.

[0018] In a preferred embodiment, the outer surface of the tightening rod 4 is uniformly provided with a plurality of hooks 6 corresponding to the filter cloth for filter pressing. When installing the filter cloth, first hang the hanging holes on the filter cloth onto the hooks 6, and then rotate the tightening rod 4 to tighten and fix the filter cloth.

[0019] In a preferred embodiment, a drive device for rotating the tensioning rods 4 is installed on the bearing housing 3. The drive device includes a drive box 5 installed on the side surface of the bearing housing 3. The ends of the two tensioning rods 4 pass through the interior of the drive box 5 and are respectively connected to a gear. The two gears mesh with each other, so that when one tensioning rod 4 on the same side rotates, it can drive the other gear to rotate in the opposite direction through the gear, thereby driving the other tensioning rod 4 to rotate synchronously. This enables quick operation to tighten and fix the two filter cloths on both sides of the main board body 1, further improving work efficiency.

[0020] One end of the tightening rod 4 extends through the outer surface of the drive box 5 and connects to the ratchet 7. The outer surface of the drive box 5 is rotatably equipped with a pawl 8 that matches the ratchet 7, and a fixing block 10 is fixedly installed on the outer surface of the drive box 5. The side surface of the fixing block 10 is equipped with an elastic plate 9 for pressing the pawl 8. The ratchet and pawl structure drives and brakes the gear of the tightening rod 4. The ratchet 7 can rotate in the direction of tightening the filter cloth. After the filter cloth is tightened and fixed, the pawl 8 presses the ratchet 7 under the pressure of the elastic plate 9, so that it will not rotate in the direction of loosening the filter cloth, thus improving the stability of the filter pressing process. When the filter cloth needs to be replaced, the operator can manually move the elastic plate 9 to make the pawl 8 no longer restrict the ratchet 7, so that it can rotate in the opposite direction to loosen the filter cloth, making it convenient to replace the filter cloth.

[0021] An optional technical solution is that a rotating handle 11 is provided on the outer surface of the ratchet 7 near its edge. The rotating handle 11 includes a fixed rod and a rotating sleeve. The fixed rod is fixedly disposed on the side surface of the ratchet 7, and the rotating sleeve is rotatably disposed on the outside of the fixed rod, so that the operator can operate the ratchet 7 by rotating the handle 11.

[0022] An optional technical solution is that the outer surface of the ratchet 7 is uniformly provided with scale lines 12 near its edge. When the operator adjusts the ratchet 7 by turning the handle 11, he can refer to the scale lines 12 to check the rotation angle or number of turns, thereby accurately stretching the filter cloth.

[0023] Alternatively, the outer surface of the drive box 5 is provided with a positioning pointer 13 corresponding to the scale line 12, which is used to provide a reference positioning in conjunction with the scale line 12, making adjustment more convenient.

[0024] Preferably, the drive device is only located at one end of the tensioning rod 4, the drive devices on the upper and lower sides of the main body 1 are located on the same side, and the drive devices on the left and right sides of the main body 1 are located on the upper side. This arrangement makes it more convenient for the operator to stretch the filter cloth through the drive device.

[0025] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
