Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to sewage treatment equipment based on submerged flat membrane separation technology. Background Art

[0002] The sewage treatment equipment based on the submerged flat membrane separation technology is an efficient and advanced sewage treatment system. The submerged flat membrane separation technology directly immerses the membrane assembly into the biochemical reaction tank and uses the efficient interception effect of the membrane to achieve solid-liquid separation. Specifically, the sewage flows between multiple flat membranes, and the dense micropores on the surface of the membrane can intercept impurities such as particles and bacteria in the water. Under the action of pressure or external suction force, clean water flows into the filter plate through the membrane holes, and then flows out to the water collection tank through the water intake of the flat membrane, thereby achieving sewage purification.

[0003] In order to improve the sewage treatment effect, conventional sewage treatment equipment based on submerged flat membrane separation technology often installs multiple flat membrane modules to increase the sewage treatment capacity. Although this treatment method can improve the sewage treatment effect, the multiple flat membrane modules are installed inside the device in a sequentially connected manner. When a single flat membrane needs to be cleaned or maintained, all the flat membrane modules in front of the flat membrane need to be disassembled in turn, and the overall maintenance efficiency is low.

[0004] When performing maintenance on a single flat-plate membrane assembly, not only the flat-plate membrane needs to be disassembled, but also the water intake above all the flat-plate membrane assemblies at the front end and the water collection assembly need to be disassembled, resulting in high overall disassembly difficulty and inability to quickly disassemble the water intake channel of a single flat-plate membrane assembly, which urgently needs improvement. Summary of the invention

[0005] The object of the present invention is to provide a sewage treatment device based on submerged flat membrane separation technology to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a sewage treatment equipment based on submerged flat membrane separation technology, comprising a box frame, the side surfaces of the box frame are provided with slots at equal intervals, the insides of the slots are movably connected with flat membrane components, the flat membrane components are displaced up and down relative to the slots, water collecting boxes are fixedly installed at equal intervals on the top of the inner cavity of the box frame, every two of the water collecting boxes are connected by a water collecting pipe, the water collecting pipes located on the left and right sides pass through the left and right sides of the box frame, a transverse guide rail is fixedly installed in the middle of the bottom end of the water collecting box, an electric push rod is fixedly installed in the middle of the bottom end of the transverse guide rail, a linkage component is fixedly installed on the output end of the electric push rod, the transverse guide rail and the linkage component are movably connected, a water suction hose is fixedly sleeved on the front and rear sides of the linkage component, the bottom end of the water suction hose is fixedly connected to the top of the flat membrane component, the top of the water suction hose is fixedly connected to the water collecting box, and the left and right sides of the linkage component are installed with self-locking components located on the left and right sides of the flat membrane component.

[0007] In actual use, multiple flat membrane assemblies can be connected to the card slots, and the flat membrane assemblies can be fixed to the water pumping hoses. At the same time, the water collecting pipes need to be connected to the external water pumping devices. At the same time, an aeration device is installed at the bottom of the box frame, and the entire device is inserted into the water to complete the preparations before sewage treatment.

[0008] As a further technical solution of the present invention, the flat membrane assembly includes a support frame, a porous microfiltration membrane is fixedly installed inside the support frame, and clamping strips are fixedly installed at both the front and rear ends of the support frame. The support frame is movably connected between the clamping strips and the clamping slots.

[0009] As a further technical solution of the present invention, water intake pipes are installed on both the front and rear sides of the top of the support frame, the water intake pipes are connected to the porous microfiltration membrane, the water intake pipes are movably connected to the water suction hose, and the water intake pipes are connected to the water suction hose.

[0010] As a further technical solution of the present invention, a mounting hole is opened in the middle of the top of the support frame, and limiting holes located at the upper and lower ends of the mounting hole are opened on the left and right sides of the support frame, and the mounting hole and the limiting hole are movably connected with the self-locking component.

[0011] When treating sewage, the external pumping device can be turned on, and negative pressure can be generated in the treatment pool. The sewage will automatically rise to the porous microfiltration membrane, and after being filtered by multiple porous microfiltration membranes, it will be discharged through the water intake pipe. At this time, the sewage can enter the interior of the pumping hose, and enter the interior of multiple water collecting tanks through the pumping hose. Finally, after being gathered through the water collecting pipe, it is discharged from the water collecting pipes at the left and right ends, completing the sewage filtration process.

[0012] As a further technical solution of the present invention, the linkage assembly includes a linkage frame, the front and rear ends of the linkage frame are fixedly connected to the outer side surfaces of two water suction hoses, the middle part of the linkage frame is connected to the output end of the electric push rod, and the first fixed seat is fixedly installed on the left and right sides of the top of the linkage frame.

[0013] As a further technical solution of the present invention, one end of the first fixed seat away from the linkage frame is movably connected to a connecting rod via a rotating shaft, and one end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft. A guide block is fixedly installed on the top of the second fixed seat, and the guide block is movably clamped with the transverse guide rail.

[0014] When it is necessary to disassemble the water pumping hose and the water intake pipe, the electric push rod can be turned on and controlled to shorten, and the linkage frame can be driven to rise accordingly. At this time, the distance between the linkage frame and the transverse guide rail is reduced accordingly. When the linkage frame rises, the two water pumping hoses are driven to move upward until the connection between the water pumping hose and the water intake pipe is released, and the water intake channel can be cut off at this time.

[0015] During installation, the electric push rod can be controlled to extend, which can drive the linkage frame to descend and drive the water suction hose to move downward until the water suction hose and the water intake pipe are fully connected, so that the water intake channel can be connected and the water intake channel can be quickly established and cut off.

[0016] By utilizing the coordination between the electric push rod, the linkage assembly and the water suction hose, that is, by using the electric push rod to actively rise and fall the linkage frame, quickly driving the water suction hose to rise and fall, the water intake channel can be quickly established and cut off. The whole process is completed quickly, so that when maintaining a single flat membrane assembly alone, the channel can be quickly cut off and established, which significantly shortens the maintenance time and improves the maintenance efficiency.

[0017] As a further technical solution of the present invention, the self-locking component includes an extension frame, one end of which passes through one side of the transverse guide rail and is connected to one side of the guide block, and a mounting plate is fixedly installed at the bottom end of the extension frame close to the transverse guide rail.

[0018] As a further technical solution of the present invention, the mounting plate is located on the front side of the support frame, a mounting rod is fixedly installed in the middle of the mounting plate close to the support frame, and limiting rods are fixedly installed at the upper and lower ends of the mounting plate close to the support frame.

[0019] As a further technical solution of the present invention, when the water intake pipe and the water suction hose are movably connected, the distance between the two mounting plates is the minimum, and the mounting plates and the mounting holes are movably connected, and the limit rods and the limit holes are movably connected.

[0020] When maintaining a single flat membrane assembly, due to the rise of the linkage frame, the two connecting rods at the top can be driven to deflect in the direction away from the middle. At this time, the two guide blocks are displaced relative to the transverse guide rail, that is, the two guide blocks are driven to move away from each other. At this time, the two extension frames are driven to move away from each other, and the two mounting plates are driven to move away from each other, automatically releasing the clamping connection between the mounting rod and the mounting hole, and the clamping connection between the limit rod and the limit hole. At this time, the support frame is no longer connected to the self-locking component, and the support frame can be pulled out downward to complete the rapid disassembly process of a single support frame;

[0021] During installation, it is only necessary to movably connect the support frame and the slot, and the mounting rod and the mounting hole must correspond to each other, and then turn on the electric push rod to extend and drive the linkage frame to descend. At this time, the two mounting plates can be driven closer to each other until the mounting rod and the mounting hole are engaged with each other, and the limit rod and the limit hole are engaged with each other, thereby completing the automatic installation of the support frame and the installation between the water intake pipe and the water suction hose.

[0022] By utilizing the device to automatically establish and automatically cut off the pumping channel, and through the cooperation between the linkage component and the self-locking component, the device can automatically complete the installation of a single flat membrane component after establishing the pumping channel, and can automatically complete the disassembly of a single flat membrane component after the pumping channel is automatically released. The entire process is completed synchronously, and the flat membrane component at any position can be quickly disassembled and assembled without disassembling the flat membrane component at the front end, which significantly shortens the maintenance time and further improves the maintenance efficiency.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) The present invention utilizes the cooperation between the electric push rod, the linkage assembly and the water pumping hose, that is, the electric push rod is used to realize the active rise and fall of the linkage frame, and the water pumping hose is quickly driven to rise and fall, so as to quickly establish and cut off the water intake channel. The whole process is completed quickly, so that when a single flat membrane assembly is maintained separately, the channel can be quickly cut off and established, which significantly shortens the maintenance time and improves the maintenance efficiency.

[0025] (2) The present invention utilizes the process of automatically establishing and automatically cutting off the pumping channel by utilizing the device. Through the cooperation between the linkage component and the self-locking component, the device can automatically complete the installation of a single flat membrane component after establishing the pumping channel, and can automatically complete the disassembly of a single flat membrane component after the pumping channel is automatically released. The entire process is completed synchronously, and the flat membrane component at any position can be quickly disassembled and assembled without disassembling the flat membrane component at the front end, which significantly shortens the maintenance time and further improves the maintenance efficiency.

At the same time, the water collecting pipe 5 needs to be connected to the external water pumping device, and an aeration device is installed at the bottom of the box frame 1, and the entire device is inserted into the water to complete the preparations before sewage treatment.

[0038] like Figure 1 and Figure 3 as well as Figure 5 As shown, the flat membrane assembly 3 includes a support frame 301, a porous microfiltration membrane 303 is fixedly installed inside the support frame 301, and clamping strips 302 are fixedly installed at the front and rear ends of the support frame 301. The support frame 301 is movably clamped with the clamping slot 2 through the clamping strip 302. Water intake pipes 304 are installed on the front and rear sides of the top of the support frame 301. The water intake pipe 304 is connected to the porous microfiltration membrane 303. The water intake pipe 304 is movably connected to the water suction hose 8. The water intake pipe 304 is connected to the water suction hose 8. A mounting hole 305 is opened in the middle of the top of the support frame 301, and limiting holes 306 located at the upper and lower ends of the mounting hole 305 are opened on the left and right sides of the support frame 301. The mounting hole 305 and the limiting hole 306 are movably clamped with the self-locking component 10.

[0039] When treating sewage, the external pumping device can be turned on, and negative pressure can be generated in the treatment pool. The sewage will automatically rise to the porous microfiltration membrane 303, and after being filtered by multiple porous microfiltration membranes 303, it will be discharged through the water intake pipe 304. At this time, the sewage can enter the interior of the pumping hose 8, and enter the interior of multiple water collecting boxes 4 through the pumping hose 8. Finally, after being gathered through the water collecting pipe 5, it is discharged from the water collecting pipe 5 at the left and right ends, completing the sewage filtration process.

[0040] like Figure 3 and Figure 6 as well as Figure 7 As shown, the linkage assembly 9 includes a linkage frame 901, the front and rear ends of the linkage frame 901 are fixedly sleeved with the outer side surfaces of the two water suction hoses 8, the middle part of the linkage frame 901 is connected to the output end of the electric push rod 7, and the left and right sides of the top of the linkage frame 901 are fixedly installed with a first fixed seat 903, and the end of the first fixed seat 903 away from the linkage frame 901 is movably connected to a connecting rod 905 through a rotating shaft, and the end of the connecting rod 905 away from the first fixed seat 903 is movably connected to a second fixed seat 904 through a rotating shaft, and the top of the second fixed seat 904 is fixedly installed with a guide block 902, and the guide block 902 is movably clamped with the transverse guide rail 6.

[0041] Embodiment: When it is necessary to disassemble the water suction hose 8 and the water intake pipe 304, that is, when disassembling, the electric push rod 7 can be turned on and controlled to shorten, and the linkage frame 901 can be driven to rise accordingly. At this time, the distance between the linkage frame 901 and the transverse guide rail 6 is reduced accordingly. When the linkage frame 901 rises, the two water suction hoses 8 are driven to move upward until the sleeve connection between the water suction hose 8 and the water intake pipe 304 is released, and the water intake channel can be cut off at this time;

[0042] During installation, the electric push rod 7 can be controlled to extend, which can drive the linkage frame 901 to descend and drive the water suction hose 8 to move downward until the water suction hose 8 and the water intake pipe 304 are fully connected, so that the water intake channel can be connected and the water intake channel can be quickly established and cut off.

[0043] By utilizing the cooperation between the electric push rod 7, the linkage assembly 9 and the water suction hose 8, that is, the electric push rod 7 is used to realize the active rise and fall of the linkage frame 901, and the water suction hose 8 is quickly driven to rise and fall, so as to quickly realize the establishment and cutting of the water intake channel. The whole process is completed quickly, so that when a single flat membrane assembly 3 is maintained separately, the channel can be quickly cut off and established, which significantly shortens the maintenance time and improves the maintenance efficiency.

[0044] like Figure 3 and Figure 6 as well as Figure 8As shown, the self-locking component 10 includes an extension frame 101, one end of the extension frame 101 passes through one side of the transverse guide rail 6 and is connected to one side of the guide block 902, and a mounting plate 102 is fixedly installed at the bottom end of the extension frame 101 close to the transverse guide rail 6, and the mounting plate 102 is located on the front of the support frame 301, and a mounting rod 103 is fixedly installed in the middle of the mounting plate 102 close to the support frame 301. Limiting rods 104 are fixedly installed at the upper and lower ends of the mounting plate 102 close to the support frame 301. When the water intake pipe 304 and the water suction hose 8 are movably connected, the distance between the two mounting plates 102 is the minimum value, and the mounting plate 102 and the mounting hole 305 are movably connected, and the limiting rod 104 and the limiting hole 306 are movably connected.

[0045] Embodiment: When maintaining a single flat membrane assembly 3, due to the rise of the linkage frame 901, the two connecting rods 905 at the top can be driven to deflect in the direction away from the middle, and the two guide blocks 902 are displaced relative to the transverse guide rail 6, that is, the two guide blocks 902 are driven to move away from each other, and the two extension frames 101 are driven to move away from each other, and the two mounting plates 102 are driven to move away from each other, and the clamping connection between the mounting rod 103 and the mounting hole 305, and the clamping connection between the limit rod 104 and the limit hole 306 are automatically released. At this time, the support frame 301 is no longer connected to the self-locking assembly 10, and the support frame 301 can be pulled out downward to complete the rapid disassembly process of the single support frame 301;

[0046] During installation, it is only necessary to flexibly connect the support frame 301 with the slot 2, and the mounting rod 103 and the mounting hole 305 must correspond to each other, and then turn on the electric push rod 7 to extend and drive the linkage frame 901 to descend. At this time, the two mounting plates 102 can be driven close to each other until the mounting rod 103 and the mounting hole 305 are connected to each other, and the limiting rod 104 and the limiting hole 306 are connected to each other, thereby completing the automatic installation of the support frame 301 and completing the installation between the water intake pipe 304 and the water suction hose 8.

[0047] By utilizing the device to automatically establish and automatically cut off the pumping channel, through the cooperation between the linkage component 9 and the self-locking component 10, the device can automatically complete the installation of a single flat membrane component 3 after establishing the pumping channel, and can automatically complete the disassembly of a single flat membrane component 3 after the pumping channel is automatically released. The whole process is completed synchronously, and the flat membrane component 3 at any position can be quickly disassembled and assembled without disassembling the flat membrane component 3 at the front end, which significantly shortens the maintenance time and further improves the maintenance efficiency.

[0048] Working principle and usage process:

[0049] When in use, multiple flat membrane assemblies 3 can be connected to the card slots 2, and the flat membrane assemblies 3 and the water pumping hose 8 can be fixed. At the same time, the water collecting pipe 5 needs to be connected to the external water pumping device, and the aeration device is installed at the bottom of the box frame 1, and the whole device is inserted into the water to complete the preparation before sewage treatment;

[0050] When treating sewage, the external pumping device can be turned on, and negative pressure can be generated in the treatment pool. The sewage automatically rises to the porous microfiltration membrane 303, and after being filtered by multiple porous microfiltration membranes 303, it is discharged through the water intake pipe 304. At this time, the sewage can enter the interior of the pumping hose 8, and enter the interior of multiple water collection boxes 4 through the pumping hose 8. Finally, after being gathered through the water collection pipe 5, it is discharged from the water collection pipes 5 at the left and right ends, completing the sewage filtration process;

[0051] When it is necessary to disassemble the water suction hose 8 and the water intake pipe 304, that is, when disassembling, the electric push rod 7 can be turned on and controlled to shorten, and the linkage frame 901 can be driven to rise accordingly. At this time, the distance between the linkage frame 901 and the transverse guide rail 6 is reduced accordingly. When the linkage frame 901 rises, it drives the two water suction hoses 8 to move upward until the sleeve connection between the water suction hose 8 and the water intake pipe 304 is released, and the water intake channel can be cut off at this time;

[0052] During installation, the electric push rod 7 can be controlled to extend, which can drive the linkage frame 901 to descend, and drive the water suction hose 8 to move downward until the water suction hose 8 and the water intake pipe 304 are completely connected, so that the water intake channel can be connected, and the water intake channel can be quickly established and cut off;

[0053] When maintaining a single flat membrane assembly 3, due to the rise of the linkage frame 901, the two connecting rods 905 at the top can be driven to deflect in the direction away from the middle. At this time, the two guide blocks 902 are displaced relative to the transverse guide rail 6, that is, the two guide blocks 902 are driven to move away from each other. At this time, the two extension frames 101 are driven to move away from each other, and the two mounting plates 102 are driven to move away from each other, and the connection between the mounting rod 103 and the mounting hole 305, as well as the connection between the limit rod 104 and the limit hole 306 are automatically released. At this time, the support frame 301 is no longer connected to the self-locking assembly 10, and the support frame 301 can be pulled out downward to complete the rapid disassembly process of the single support frame 301;

[0054] During installation, it is only necessary to flexibly connect the support frame 301 with the slot 2, and the mounting rod 103 and the mounting hole 305 must correspond to each other, and then turn on the electric push rod 7 to extend and drive the linkage frame 901 to descend. At this time, the two mounting plates 102 can be driven close to each other until the mounting rod 103 and the mounting hole 305 are connected to each other, and the limiting rod 104 and the limiting hole 306 are connected to each other, thereby completing the automatic installation of the support frame 301 and completing the installation between the water intake pipe 304 and the water suction hose 8.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
