AI Technical Summary
In existing vibrating membrane bioreactor (V-MBR) technology, misalignment of the centerline when connecting the drive end and the carriage end, as well as vertical displacement of the carriage, can lead to equipment damage and operational instability. Furthermore, the universal bearing connection method affects vibration parameters.
The structure employs a combination of sliding connection components and spring load components, including a vertically arranged first linear shaft, a spring, a connecting front plate, and a base plate. The spring stores and releases the energy of the carriage, preventing the force from acting directly on the drive device and protecting the drive device from vertical stress.

Description
Technical Field
[0001] This invention relates to the field of water treatment technology, and in particular to a drive connection device for water treatment equipment. Background Technology
[0002] Vibrating membrane bioreactor (V-MBR) systems, as a novel membrane separation water treatment technology developed in recent years, replace the aeration and flushing methods in traditional MBR processes with periodic mechanical vibration, effectively suppressing membrane fouling while significantly reducing system operating energy consumption. This technology has now become an important technical means to support the implementation of the national "dual-carbon" strategy and wastewater resource utilization policy, demonstrating broad market application potential and industrialization value in the field of wastewater treatment.
[0003] In V-MBR technology, in order to achieve the horizontal reciprocating motion of the membrane module, the vibration drive end is rigidly connected to the carriage end through flange bolts. Through this mechanical transmission method, the kinetic energy of the drive device is effectively transmitted to the carriage assembly, which ultimately drives the vibrating membrane module assembled on the carriage to perform periodic horizontal reciprocating motion according to preset parameters.
[0004] However, a survey and analysis of existing vibrating membrane bioreactor (V-MBR) technology applications revealed the following key issues: First, when connecting the drive end and the carriage end, the vertical centerline of the flange hole is often misaligned, requiring readjustment of the drive end equipment base height and level to align the centerline before connecting the flange, which is cumbersome. Second, when the membrane module and carriage reciprocate horizontally within the membrane tank, the carriage end face experiences unexpected vertical displacement. Existing conventional flange bolt connections are rigid; when the carriage tends to displace vertically, the fixing bolts convert the displacement potential energy into a reaction force, which is transmitted to the connecting bolts and drive unit. This causes components to frequently experience vertical stress, leading to damage, severely affecting system stability and increasing maintenance costs.
[0005] While universal bearings can be used to compensate for the vertical displacement of the carriage, this solution has inherent drawbacks: the mechanism of absorbing displacement through bearing angle deflection alters the system's vibration amplitude, causing the membrane module's vibration parameters to deviate from design values, ultimately leading to a decrease in the membrane module's anti-fouling performance. This technical contradiction urgently requires a new connection solution. Summary of the Invention
[0006] The embodiments of the present invention provide a drive connection device for water treatment equipment, which solves the technical problems existing in the prior art.

[0020] The pitch lever runs through the upper support plate, the fixed plate, and the moving plate, and the bottom of the pitch lever is threaded to the moving plate; the distance between the fixed plate and the moving plate can be changed by lifting / pressing the pitch lever.
[0021] When the slide of the water treatment equipment drives the moving plate to slide up and down along the second linear axis by driving the connecting base plate, the spring can store and release the energy transmitted from the slide of the water treatment equipment to the connecting base plate.
[0022] Preferably, the elastic load component further includes a self-aligning nut, which is threadedly connected to the pitch rod and is located on top of the upper support plate; the pitch rod can be raised / lowered by rotating the self-aligning nut.
[0023] Preferably, the fixed plate has an extension, and the fixed plate is bolted to the connecting front plate through the first extension.
[0024] As can be seen from the technical solutions provided by the embodiments of the present invention above, the present invention provides a drive connection device for water treatment equipment, including a sliding connection component, a spring load component, a connecting front plate, and a connecting bottom plate; the sliding connection component includes a vertically arranged first linear shaft; the first linear shaft is mounted on the connecting bottom plate, the connecting front plate is indirectly movably connected to the linear shaft, and can slide along the surface of the linear shaft, so that the connecting bottom plate can slide up and down relative to the connecting front plate; the spring load component has a vertically arranged spring, one side of which is fixedly installed, and the other side is indirectly connected to the connecting front plate; the connecting front plate is used to connect the drive device of the water treatment equipment, and the connecting bottom plate is used to connect the slide of the water treatment equipment; when the slide of the water treatment equipment generates unexpected periodic vertical displacement during operation, the spring can store and release the energy transmitted from the slide of the water treatment equipment to the connecting bottom plate, avoiding the force generated when the slide moves up and down acting on the drive device in the water treatment equipment. The drive connection device provided by the present invention can transmit the axial horizontal force of the drive device while releasing the potential energy of the slide when it generates vertical displacement due to up and down jumping, protecting the connecting bolts and the drive device from vertical stress, thereby improving the overall structural stability.

[0037] To facilitate understanding of the embodiments of the present invention, the following will provide further explanation and description with reference to the accompanying drawings and several specific embodiments. These embodiments do not constitute a limitation on the embodiments of the present invention.
[0038] Reference Figure 1 A drive connection device for water treatment equipment includes a connecting base plate 1, a sliding connection component 2, a spring load component 3, and a connecting front plate 4.
[0039] Assembly process of drive connection device: refer to Figure 2 First, assemble two bearing seats 21, a first linear shaft 22, and a box bearing 23 into a slide rail; then, the two slide rails and a connecting front plate 24 can be assembled into a sliding connection component 2 using bolts; refer to Figure 3-4 Weld one end of the pitch rod 31 to the moving plate 36, and place the linear bearing 37 in the groove of the moving plate 36 and fix it with bolts; pass the two second linear shafts 33 through the linear bearings 37 respectively, and fit the two springs 35 on the outside of the second linear shafts 33 respectively; place the groove of the fixed plate 34 downwards, so that it passes through the pitch rod 31 and the second linear shafts 33, and insert the other end of the spring 35 into the groove of the fixed plate 34; insert the lower stepped shaft end of the second linear shaft 33 into the lower support plate 38, and pass the upper support plate 32 through the pitch rod 31 and insert it into the upper stepped shaft end of the second linear shaft 33. At this time, a spring load component 3 is assembled; refer to Figure 1 The upper support plate 32 and lower support plate 38 of the spring load component 3 are connected to the threaded holes at the shaft ends of the first linear shaft 22 in the sliding connection component 2 by bolts. At the same time, the upper part of the connecting front plate of the fixed plate 34 is fixed by three bolts. The four bearing seats 21 in the sliding connection component 2 are connected to the connecting base plate 1 by bolts. The self-aligning nut 39 is screwed into the pitch rod 31 that protrudes upward through the upper support plate 32. The fixed connecting base plate 1 pushes the connecting front plate 4, and the connecting front plate 4 drives the box bearing 23 to move smoothly on the first linear shaft 22. At this time, the drive connection device is assembled and built.
[0040] Example 1
[0041] The objective of this embodiment is to connect the carriage and the drive unit by means of the self-aligning function of the drive connection device when the center of the carriage and the center of the drive unit are not aligned.
[0042] Reference Figure 5 The connecting base plate 1 is connected to the slide with bolts. The connecting front plate 4 and the flange shaft center of the drive device are not on the same straight line, differing by 10mm. The flange bolt holes cannot be connected due to misalignment. At this time, tighten the self-aligning nut 39. Because the upper support plate 32 is fixed, the pitch rod 31 moves upward, simultaneously driving the driving plate 36 upward and compressing the spring 35. After the elastic force generated by the compression of the spring 35 is equal to the weight of the box bearing 23 and the connecting front plate 4, continue to tighten the self-aligning nut 39. Because the fixed plate 34 is connected to the connecting front plate 4, it drives the box bearing 23 and the connecting front plate 4 to move upward until they are adjusted to a suitable position, so that the connecting front plate 4 and the flange shaft center of the drive device are aligned. At this time, the drive device moves to the left, and the corresponding connecting holes of the flange are exactly aligned with the openings on the connecting front plate 4, and are connected by bolts.
[0043] Example 2
[0044] The objective of this embodiment is to transmit the axial horizontal force of the drive device through the drive connection device, while also counteracting or releasing the potential energy of the slide when it undergoes vertical displacement due to up-and-down jumping, thus protecting the connecting bolts and drive device from vertical stress and improving the overall structural stability.
[0045] refer to Figure 6 After the slide and drive device are installed according to the method of Example 1 via the drive connection device, during the normal operation of the vibrating membrane bioreactor (V-MBR) system, the slide end face will generate unexpected jumping displacement in the vertical direction. Since the slide is fixedly connected to the connecting base plate 1 by bolts, the connecting base plate 1 will jump vertically with the same displacement. Similarly, the two pairs of bearing seats 21 fixedly connected to the connecting base plate 1 by bolts drive the two first linear shafts 22 to jump vertically with the same displacement. At the same time, the connecting front plate 4 is connected to the flange shaft of the drive device and is in an absolutely stationary state in the vertical direction. The two box bearings 23 fixedly connected to the connecting front plate 4 by bolts are also in an absolutely stationary state in the vertical direction, just like the connecting front plate 4. Because the box bearings 23 can slide flexibly along the axis on the first linear shafts 22, at this time, refer to Figure 6 The box bearing 23, connecting front plate 4, drive device flange shaft, which are outlined by double-dotted lines, are in a relative sliding state with the first linear shaft 22, bearing seat 21, connecting base plate 1, and slide in the vertical direction.
[0046] At the same time, the drive device flange shaft reciprocates along the axis in the horizontal direction, and its push and pull force is transmitted to the slide in sequence through the connecting front plate 4, box bearing 23, first linear shaft 22, bearing seat 21, and connecting base plate 1, thereby driving the slide to achieve reciprocating operation in the horizontal direction.
[0047] In summary, this invention provides a drive connection device for water treatment equipment, comprising a sliding connection component, a spring load component, a connecting front plate, and a connecting base plate. The sliding connection component includes a vertically arranged first linear shaft. The first linear shaft is mounted on the connecting base plate, and the connecting front plate is indirectly movably connected to the linear shaft and can slide along the surface of the linear shaft, allowing the connecting base plate to slide up and down relative to the connecting front plate. The spring load component has a vertically arranged spring, with one side of the spring fixedly installed and the other side indirectly connected to the connecting front plate. The connecting front plate is used to connect the drive device of the water treatment equipment, and the connecting base plate is used to connect the slide of the water treatment equipment. When the slide of the water treatment equipment generates unexpected periodic vertical displacement during operation, the spring can store and release the energy transmitted from the slide of the water treatment equipment to the connecting base plate, preventing the force generated by the vertical displacement of the slide from acting on the drive device in the water treatment equipment. The drive connection device provided by this invention can transmit the axial horizontal force of the drive device while releasing the potential energy of the slide due to vertical displacement caused by vertical jumping, protecting the connecting bolts and the drive device from vertical stress, thereby improving the overall structural stability.
