Description
Technical Field
[0001] This utility model belongs to the field of filtration equipment technology, specifically, it relates to a segmented, easily detachable filter roller device for a microfiltration machine. Background Technology
[0002] Microfiltration machines, as highly efficient solid-liquid separation equipment, play a crucial role in municipal wastewater treatment, industrial wastewater purification, aquaculture water recycling, and drinking water pretreatment. They effectively reduce water turbidity and improve water quality by trapping suspended particulate matter, colloids, algae, and other impurities in the water through filter screens, laying a solid foundation for subsequent treatment processes. With increasingly stringent environmental protection requirements and growing demand for water resource recycling, the application scenarios for microfiltration machines are continuously expanding, market demand is steadily rising, and they have broad application prospects.
[0003] However, most microfiltration drums on the market currently use a one-piece structure. During actual operation, due to the continuous impact of water flow, the filter screen is prone to breakage due to excessive localized stress during impurity sieving. Simultaneously, the overall drum structure may also suffer from tearing due to prolonged load. Therefore, once a malfunction occurs, replacing the filter screen requires disassembling the entire drum, a time-consuming maintenance process. Thus, considering the above, existing microfiltration technologies suffer from structural instability, disassembly difficulty, and low replacement efficiency when replacing one-piece filter screens or drums. Utility Model Content
[0004] In view of this, the present invention provides a segmented, easily detachable roller device for microfiltration machines, which can solve the problems of unstable structure, difficult disassembly, and low replacement efficiency of integrated rollers.
[0005] This utility model is implemented as follows:
[0006] This utility model provides a segmented, easily detachable filter roller device for a microfiltration machine, comprising a roller with one end connected to a main shaft and the other end movably connected to a bearing. The roller consists of two sets of first filter sections and two sets of second filter sections connected by a flange structure. The outer ends of the second filter sections are respectively provided with two sets of protruding connecting ears. The connecting ears are fixedly connected by two cross-arranged baffles, and the baffles have a coupling through hole in the middle that passes through the main shaft. Each filter section has a baffle arranged on its surface, and the baffles have a gauge around their edges.
[0007] The technical advantages of the segmented, easily detachable filter roller device for microfiltration machines provided by this utility model are as follows: By designing the roller structure into four segments, which are connected by flange structures to form a complete roller, a fixing ring can be formed through the flange structure, and the support strength of the roller frame can be improved. When damage occurs and replacement is needed, each segment can be disassembled independently, which greatly shortens the maintenance and replacement time, reduces the difficulty, and improves efficiency. The baffle and the gauge can reduce the stress and wear on the filter screen and reduce the failure frequency.
[0008] Based on the above technical solution, the segmented, easily detachable filter roller device for a microfiltration machine of this utility model can be further improved as follows:
[0009] The first set of filter screens is connected by a flange structure to form the first cylinder of the drum, and the second set of filter screens is connected by a flange structure to form the second cylinder of the drum; a transverse reinforcing rib is formed at the transverse flange structure connection; a flange structure is formed around both ends of the first cylinder, and the inner end of the second cylinder is fixedly installed to the inner end of the first cylinder by bolts and flange structure.
[0010] The beneficial effects of adopting the above-mentioned improvement scheme are: the strength of the skeleton structure is enhanced by the flange structure connection, making it less prone to deformation when the drum is working.
[0011] Furthermore, the flange structure on both sides forms longitudinal reinforcing ribs; the surfaces of the first and second cylinders are densely covered with through holes for installing filter screens, and the filter screens are connected to the cylinders by bolts; the filter screens are selected with a filtration accuracy of 300 to 600 mesh.
[0012] The advantages of adopting the above-mentioned improved solution are: when a filter is replaced due to a malfunction, only one section needs to be replaced, saving about two-thirds of the time compared to replacing the entire filter in the original integrated design; at the same time, it is more cost-effective than replacing the entire filter in the original integrated design.
[0013] Furthermore, the two ends of the stop bar are respectively provided with connecting parts that are bent at 90°, and the connecting parts are provided with mounting through holes corresponding to the connecting ears, and are fixedly installed by bolts corresponding to the through holes on the connecting ears.
[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a stop bar and a 90° bent connection, compared with the fixed connection between the stop bar and the roller in the integrated roller, the stop bar can be disassembled separately without moving the entire roller. The bolt connection makes the disassembly operation more convenient and reduces the disassembly time.
[0015] Furthermore, the ruler bends outward along the spoiler to form a 75°-90° angle.
[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by designing the 75°-90° bend angle of the filter ruler, the efficiency of impurity discharge can be enhanced, filter screen clogging and wear can be reduced, and the replacement frequency due to filter screen damage can be reduced.
[0017] Furthermore, the stop bar includes a first stop bar and a second stop bar. The first stop bar is located at the inner end, and the second stop bar is located at the outer end. The two are coaxially stacked and aligned through a connecting hole, and their two ends are fixedly connected to the connecting ears through connecting parts.
[0018] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by designing the first and second stop rods to be cross-stacked and fixed by bolts, it not only supports the connecting main shaft to meet the rolling of the roller, but also differs from the overall structure of the one-piece stop rod, allowing a single stop rod to be disassembled without removing the entire stop rod assembly. The bolt connection makes disassembly more convenient and shortens the replacement time.
[0019] Furthermore, the first stop has through holes around the coupling through hole for fixing and installing the coupling seat, which is fixedly connected to the coupling seat by bolts, and the coupling seat is movably connected to the main shaft.
[0020] Furthermore, the outer end of the first cylinder is installed with a side flange via a flange. A water inlet is provided at the axial position of the side flange, and a mounting hole for installing a coupling flange is provided on the outer periphery of the water inlet.
[0021] Furthermore, the coupling flange is fixedly connected to the side flange by bolts corresponding to the mounting hole positions.
[0022] Furthermore, the outer end of the coupling flange is fixedly connected to the side flange, and the inner end is movably connected to the bearing. A water inlet is also provided at the shaft center of the coupling flange, which is used to connect the water inlet pipe.
[0023] Compared with existing technologies, the beneficial effects of the segmented, easily detachable filter roller device for microfiltration machines provided by this utility model are as follows: The segmented roller is formed by connecting two sets of first filter sections and two sets of second filter sections with a flange structure, unlike the integral structure of existing one-piece rollers. The flange connection allows for quick separation of each filter section via disassembly bolts, solving the problem of requiring complete removal when disassembling an integral roller. The cross-shaped baffles are fixed by connecting ears, allowing for individual removal of the baffles compared to the fixed structure of an integral roller, reducing the replacement range. The baffles and guide gauges reduce filter wear and tear, lowering the frequency of failures and indirectly shortening replacement time, resulting in improved disassembly convenience and reduced replacement time overall.

[0032] like Figure 1-4 The image shows an embodiment of a segmented, easily detachable filter roller device for a microfiltration machine provided by this utility model. In this embodiment, it includes a roller 10 with one end connected to the main shaft and the other end movably connected to a bearing. The roller is composed of two sets of first filter sections 11 and two sets of second filter sections 12 connected by a flange structure. The outer ends of the second filter sections are respectively provided with two sets of protruding connecting ears 13. The connecting ears are fixedly connected by two cross-arranged baffles 14, and the baffles have a coupling through hole 15 that penetrates the main shaft in the middle. Each filter section has a baffle 16 arranged on its surface, and a ruler 161 is provided on the edge of the baffle.
[0033] In the above technical solution, two sets of first filter screens are connected by a flange structure to form the first cylinder 101 of the roller, and two sets of second filter screens are connected by a flange structure to form the second cylinder 102 of the roller; a transverse reinforcing rib 17 is formed at the transverse flange structure connection; a flange structure 18 is formed around both ends of the first cylinder, and the inner end of the second cylinder is fixedly installed with the inner end of the first cylinder by bolts to the flange structure.
[0034] Furthermore, in the above technical solution, the flange structure on both sides forms longitudinal reinforcing ribs 19; the surfaces of the first and second cylinders are densely covered with through holes for installing the filter screen 20, and the filter screen is connected to the cylinder by bolts; the filter screen is selected with a filtration accuracy of 300 to 600 mesh.
[0035] Furthermore, in the above technical solution, the two ends of the stop bar are respectively provided with connecting parts 21 that are bent at 90°, and the connecting parts are provided with mounting through holes corresponding to the connecting ears, and are fixedly installed by bolts corresponding to the through holes on the connecting ears.
[0036] Furthermore, in the above technical solution, the ruler bends outward along the spoiler to form a 75°-90° angle.
[0037] Preferably, the bending angle of the ruler outward is 90° when in use.
[0038] Furthermore, in the above technical solution, the stop bar includes a first stop bar 141 and a second stop bar 142. The first stop bar is located at the inner end, and the second stop bar is located at the outer end. The two are coaxially and superimposed through the connecting through hole, and the two ends are fixedly connected to the connecting ear through the connecting part.
[0039] The connecting lugs are provided with mounting through holes, and the corresponding positions of the connecting parts are also provided with mounting through holes. The parts are locked and fixed by a bolt on one end and a nut on the other end.
[0040] Furthermore, in the above technical solution, the first stop rod is provided with a through hole around the coupling through hole for fixing and installing the coupling seat 22, and is fixedly connected to the coupling seat by bolts, and the coupling seat is movably connected to the main shaft.
[0041] Furthermore, in the above technical solution, the outer end of the first cylinder is installed with the side flange 23 via a flange, and the side flange has an inlet 24 at the axial position, and the inlet has a mounting hole for installing the coupling flange 25.
[0042] Furthermore, in the above technical solution, the coupling flange is fixedly connected to the side flange by bolts corresponding to the mounting hole positions.
[0043] Furthermore, in the above technical solution, the outer end of the coupling flange is fixedly connected to the side flange, and the inner end is movably connected to the bearing. A water inlet is also provided at the axial position of the coupling flange, and the water inlet is used to connect the water inlet pipe.
[0044] The roller is connected to one end of the bearing, and the water inlet pipe of the microfilter (not shown in the figure) extends from the water inlet of the side flange and the coupling flange to the inside of the roller, without interfering with the rotation of the roller.
[0045] Specifically, the principle of this utility model is as follows: During use, the main shaft and bearing inside the microfilter correspond to the coupling seat end and coupling flange end of the filter cartridge, respectively, allowing the roller to rotate inside the microfilter via water flow. Water enters the roller through the inlet pipe and is filtered through the fine mesh of the filter screen, with impurities trapped on the screen surface. The agitator creates water flow disturbance as the roller rotates. Since the first and second filter screen sections are connected by flanges and bolts, forming detachable first and second cylinders, if a section of the filter screen or cylinder is damaged during operation, the corresponding flange bolts can be removed individually to separate that section (e.g., removing only one side of the second filter screen section), without needing to disassemble the entire roller. The stop bar is fixed by connecting ears, and their cross-arrangement enhances structural stability. Its bolted connection to the coupling seat and coupling flange facilitates independent assembly and disassembly. This solves the problem of difficult and time-consuming maintenance of integrated rollers, significantly reducing downtime during maintenance.
