Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to an integrated frame membrane filter. Background Technology

[0002] In the field of water treatment, membrane filtration technology is widely used. As a core piece of equipment, the structural design of the membrane filter affects the treatment effect, cost, and maintenance. Traditional membrane filters often have membrane modules installed separately in the tank, with the tank body and frame connected in a scattered manner, resulting in low stability and integration. At the same time, depending on the usage requirements, corresponding air and water supply pipelines need to be installed in the tank body, which greatly increases the load on the frame, leading to a decrease in the frame's service life. It also occupies the effective space in the tank, reducing the fill density and effective filling volume of the filter membrane. Under the same filter membrane volume and treatment scale, this indirectly increases the effective volume of the tank body and the manufacturing cost. Therefore, an integrated frame membrane filter is needed to solve the above problems. Utility Model Content

[0003] In response to the above situation and to overcome the shortcomings of the existing technology, this device provides an integrated frame membrane filter. The hollow frame of this device gives it good stability and strong load capacity, while optimizing the water treatment space of the membrane filter, increasing the packing density of the filter membrane and improving the water treatment efficiency.

[0014] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0015] according to Figures 1 to 5 As shown, the integrated frame membrane filter includes a lower frame 1, an upper frame 2 fixedly connected to the top of the lower frame 1, multiple sealing plates 5 fixedly connected around the upper frame 2, a partition 6 and a water storage base plate 8 fixedly connected to the inner side of the upper frame 2, a supporting base plate 12 fixedly connected to the top of the lower frame 1, and a drain outlet 121 opened on the surface of the supporting base plate 12. The upper frame 2 forms an inlet chamber 3 and a water storage chamber 4 through the partition 6, the supporting base plate 12, the water storage base plate 8 and the multiple sealing plates 5. A drain outlet 121 is opened at the bottom of the partition 6. The water inlet 61 is used to connect the water inlet chamber 3 and the water storage chamber 4. A hollow aeration frame 7 is fixedly connected to the bottom of the water storage chamber 4, and a hollow water outlet frame 11 is fixedly connected to the top of the water storage chamber 4. An aeration pipe 71 and a water inlet pipe 9 are embedded on the surface of the water storage base plate 8. The aeration pipe 71 is connected to and communicates with the aeration frame 7. A water outlet 115 is opened on the surface of the support base plate 12. The water outlet 115 is connected to and communicates with the water outlet frame 11. A filter mechanism 10 for water treatment is fixedly connected inside the water storage chamber 4.

[0016] In specific implementation, a water storage space is formed inside the upper frame 2 through the supporting base plate 12 at the top of the lower frame 1 and the sealing plate 5 around the upper frame 2. This water storage space is further divided into an inlet chamber 3 and a storage chamber 4 by a partition 6. The bottom of the inlet chamber 3 is a storage base plate 8, and the bottom of the storage chamber 4 is a supporting base plate 12. The inlet chamber 3 can temporarily store the water to be treated, while the water inlet hole 61 at the bottom of the partition 6 transports this portion of water to the storage chamber 4 for treatment. The inlet pipe 9 can be connected to a water conveying device, which transports the water to be treated into the inlet chamber 3 through the inlet pipe 9. The water in the inlet chamber 3 is then transported into the storage chamber 4 through the inlet hole 61 at the bottom of the partition 6. The water is filtered by the filtration mechanism 10 in the storage chamber 4. Both the outlet frame 11 and the aeration frame 7 are hollow. The aeration frame 7 can be connected and communicated with an aerator. The generated gas is transported to the water storage chamber 4 through the hollow aeration frame 7. The aeration creates turbulence in the water stored in the water storage chamber 4, thereby improving the water treatment effect. The treated pure water is pumped to the outlet pipe through the hollow outlet frame 11 located on the upper part of the water storage chamber 4. Then, the treated pure water is discharged from the membrane filter through the outlet 115 set on the supporting base plate 12. At the same time, the particulate matter generated during water treatment falls to the bottom of the water storage chamber 4 for collection and is discharged through the drain outlet 121. The hollow aeration frame 7 and outlet frame 11 facilitate the transportation of pure water and aeration, avoiding the need for corresponding pipelines to be arranged in the device for transporting gas and pure water. At the same time, it optimizes the water treatment space of the membrane filter, improves the space utilization rate in the water storage chamber 4, and the connection between the frames effectively improves the stability and load capacity of the device and extends the service life of the membrane filter.

[0017] Furthermore, the water outlet frame 11 includes a hollow water outlet pipe 111, and multiple hollow crossbars 112 are fixedly connected between the inner sides of the water outlet pipe 111. Multiple water inlets 113 are opened on both sides of the crossbars 112. A water outlet pipe 114 is fixedly connected to the bottom of the water outlet pipe 111, and the other end of the water outlet pipe 114 is connected to and communicates with the water outlet 115.

[0018] In practical implementation, multiple water inlets 113 are provided on both sides of the crossbar 112. The water inlets 113 can transport the pure water from the upper layer through the crossbar 112 and the water outlet pipe 111 to the water outlet pipe 114, and then through the water outlet pipe 114 to the pure water outlet 115. The hollow structure of the water outlet frame 11 can serve as a pure water delivery pipe, reducing the number of pipes laid in the water storage chamber 4, reducing the load on the frame, and extending the service life of the frame.

[0019] Furthermore, the aeration frame 7 includes an aeration pipe 71, the bottom end of which is connected to an aerator, and a hollow air supply pipe 72 is fixedly connected to the top end of the aeration pipe 71. The other end of the air supply pipe 72 is fixedly connected to a hollow first air supply frame 73. The outer side of the first air supply frame 73 is fixedly connected to the upper frame 2. The bottom of the first air supply frame 73 is fixedly connected to and connected to multiple connecting pipes 74. The multiple connecting pipes 74 are fixedly connected to and connected to a second air supply frame 75. The second air supply frame 75 is fixedly connected to the upper frame 2. The bottom of the second air supply frame 75 has multiple aeration ports 76.

[0020] In practical implementation, the bottom end of the aeration pipe 71 is connected to the aerator. The aerator can be an existing aeration device used to generate aeration during water treatment. The gas generated by the aerator is transported to the first air conveying frame 73 through the aeration pipe 71. The gas is then transported to the second air conveying frame 75 located at the bottom of the water storage chamber 4 through the first air conveying frame 73. Subsequently, the gas is discharged through multiple aeration ports 76 opened at the bottom of the second air conveying frame 75. The second air conveying frame 75 located at the bottom of the water storage chamber 4 can transport the gas into the water storage chamber 4, thereby making the transported gas generate a better aeration effect, which in turn causes turbulence in the water body and improves the water treatment effect. At the same time, using the aeration pipe 71 and the hollow first air conveying frame 73 and second air conveying frame 75 as gas transport pipelines saves space in the water storage chamber 4.

[0021] Furthermore, the filtration mechanism 10 includes a mounting frame 101, which is fixedly connected to the inner side of the upper frame 2. A plurality of filter membranes 102 are fixedly connected to the inner side of the mounting frame 101, and the bottom of the filter membranes 102 is fixedly connected to a support frame 103 fixedly connected to the inner side of the second gas delivery frame 75.

[0022] In practical implementation, the installation frame 101 and the support frame 103 are distributed vertically, and multiple filter membranes 102 are arranged in parallel between the vertically distributed installation frame 101 and support frame 103. The filter membranes 102 can be submersible curtain membranes. The water is filtered through the filter membranes 102. Multiple sets of filter membranes 102 can be installed using the installation frame 101 and support frame 103, which effectively improves the water treatment effect.

[0023] Furthermore, the bottom of the support base plate 12 is set in a cone shape, and the drain outlet 121 is located at the lowest point of the support base plate 12.

[0024] In practice, the support base plate 12 is set in a cone shape to facilitate the settling of particulate matter in the water onto the upper surface of the support base plate 12, thereby facilitating the discharge of particulate matter through the drain outlet 121.

[0025] Furthermore, the height of the inlet 113 is higher than the height of the outlet 115.

[0026] In practical implementation, both the outlet pipe 111 and the crossbar 112 are located on the upper layer of the water storage chamber 4. The inlets 113 on both sides of the crossbar 112 facilitate the extraction of pure water from the upper layer. At the same time, the outlet pipe 114 connected to the bottom of the outlet pipe 111 transports pure water to the outlet 115 on the surface of the support base plate 12 for discharge. Since the height of the inlets 113 on both sides of the crossbar 112 is located on the upper layer of the water storage chamber 4, and the outlet 115 at the bottom of the outlet pipe 114 is located above the lower frame 1, the siphon principle generated by the height difference between the inlets 113 and the outlet 115 allows pure water to be naturally discharged outward through the outlet 115. This eliminates the need for a dedicated pumping mechanism to extract pure water, reducing the operating cost of the membrane filter for enterprises and improving the pure water output efficiency.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
