Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a wastewater treatment device with an antifouling membrane. Background Technology

[0002] Antifouling membranes are less affected by particles, colloidal particles, or solute macromolecules in wastewater during the filtration process, and have a longer service life than conventional wastewater filtration membranes. Currently, antifouling membranes are mostly used in conjunction with polyester nonwoven fabric, and the impurities filtered out of the wastewater will adhere to the inside of the polyester nonwoven fabric.

[0003] To ensure wastewater treatment efficiency, the filtered impurities need to be removed and discharged regularly. To ensure the efficiency of impurity removal, most existing technologies use nozzles to achieve the cleaning process. However, due to the limited number of nozzles, there are often cleaning dead corners on the inner surface of the polyester nonwoven fabric during the nozzle rotation cleaning process, which can easily lead to impurity residue.

[0004] Therefore, it is necessary to invent an anti-fouling membrane wastewater treatment device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-fouling membrane wastewater treatment device that avoids cleaning dead zones caused by the gap between adjacent nozzles, resulting in better actual cleaning effect and effectively reducing impurity residue. Furthermore, it utilizes only the driving force of the cleaning liquid spraying out, eliminating the need for additional driving components. This addresses the problem mentioned in the background art where, to ensure impurity removal efficiency, most existing technologies use nozzles for the cleaning process. However, due to the limited number of nozzles, cleaning dead zones often exist on the inner surface of the polyester nonwoven fabric during the nozzle's rotating cleaning process, easily leading to impurity residue.

[0006] According to one aspect of this disclosure, the following technical solution is provided: an antifouling membrane wastewater treatment device, comprising:

[0007] Wastewater treatment assembly, the wastewater treatment assembly being used for filtering wastewater;

[0008] Cleaning agent delivery mechanism, wherein the cleaning agent delivery mechanism is used to output cleaning agent and drive multiple sets of rotating cleaning components to revolve; and

[0009] Multiple sets of evenly distributed rotating cleaning components, each set of which includes a branch pipe fixedly installed through the outside of the rotating tube. A hollow turntable is rotatably sleeved at the outer end of the branch pipe away from the rotating tube via a bearing. Multiple cleaning holes are evenly opened on the side of the hollow turntable away from the branch pipe. Four push tubes are evenly fixedly installed through the outer side of the hollow turntable.

[0010] According to at least one embodiment of the present disclosure, the wastewater treatment device with an antifouling membrane includes a housing, an inlet pipe fixedly disposed through the center of the top of the housing, and an outlet pipe fixedly disposed through the center of the bottom of the housing.

[0011] According to at least one embodiment of the antifouling membrane wastewater treatment device of the present disclosure, a filter cylinder is fixedly disposed at the top of the inner cavity of the housing, an antifouling membrane is bonded and fixedly disposed on the top inner side of the filter cylinder, and a polyester nonwoven fabric is bonded and fixedly disposed on the inner side of the antifouling membrane.

[0012] According to at least one embodiment of the antifouling membrane wastewater treatment apparatus of the present disclosure, the cleaning agent transmission mechanism includes a rotating tube rotatably nested in the center of the inner cavity of the filter cylinder via a bearing, and a first sealing element is provided between the rotating tube and the filter cylinder.

[0013] According to at least one embodiment of the antifouling membrane wastewater treatment device of the present disclosure, the bottom end of the rotating tube is connected to a servo motor fixedly disposed at the bottom of the filter cylinder, a waterproof cover fixedly disposed at the bottom of the filter cylinder is sleeved on the outside of the servo motor, the power supply wire of the servo motor passes through the waterproof cover and extends to the outside of the housing, and a second sealing element is provided between the power supply wire and the waterproof cover.

[0014] According to at least one embodiment of the antifouling membrane wastewater treatment device of the present disclosure, a fixed frame is rotatably sleeved on the outer top of the rotating tube and fixedly installed inside the inlet pipe via a bearing, and an inlet pipe is rotatably connected to the top of the rotating tube via a rotary joint and fixedly installed through the side of the inlet pipe, and a booster pump is fixedly installed on the inlet pipe and fixedly installed on the top of the housing.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features multiple evenly distributed rotating cleaning components. The cleaning agent, once inside the rotating tube, enters multiple hollow turntables through branch pipes and is then sprayed onto the inner side of the polyester nonwoven fabric through multiple cleaning holes. During this process, a servo motor drives the rotating cleaning components to revolve around the rotating tube. Simultaneously, the cleaning agent is sprayed out from multiple push pipes on the outer side of the hollow turntables. Due to the pushing force of the sprayed cleaning agent, the hollow turntables revolve around the tubes while simultaneously rotating around the branch pipes, causing the multiple cleaning holes to rotate. Compared to existing technologies, this invention avoids cleaning dead zones caused by gaps between adjacent nozzles, resulting in better cleaning performance and effectively reducing impurity residue. Furthermore, it utilizes only the pushing force of the sprayed cleaning liquid, eliminating the need for additional drive components. Attached Figure Description

[0027] Figure 2 This is a schematic diagram of the wastewater treatment component 1 of an antifouling membrane wastewater treatment apparatus according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the cleaning agent transfer mechanism 2 and the rotating cleaning assembly 3 of an antifouling membrane wastewater treatment device according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the antifouling membrane wastewater treatment device disclosed herein solves the problems of dead corners and impurity residues in traditional nozzle cleaning through the synergistic effect of components such as wastewater treatment component 1, cleaning agent transmission mechanism 2 and multiple sets of evenly distributed rotating cleaning components 3. It is suitable for the filtration treatment of municipal sewage and light industrial wastewater (such as pretreatment of dyeing and printing wastewater, food processing wastewater, etc.).

[0030] like Figure 2 As shown in this disclosure, the wastewater treatment component 1 includes a shell 11, which is a cylindrical structure made of 304 stainless steel. It is resistant to wastewater corrosion and has high strength. The FRP is lightweight and resistant to acids and alkalis, making it suitable for industrial wastewater scenarios. An inlet pipe 12 is fixedly installed through the center of the top of the shell 11, and an outlet pipe 13 is fixedly installed through the center of the bottom of the shell 11. Both are made of the same material as the shell 11. A filter cylinder 14 is fixedly installed at the top of the inner cavity of the shell 11. It is also made of 304 stainless steel and the inner wall is polished. An antifouling membrane 15 is bonded and fixedly installed on the top of the inner side of the filter cylinder 14. The antifouling membrane is made of PVDF material. The PVDF antifouling membrane has strong antifouling resistance and slow flux decay. The epoxy adhesive is resistant to wastewater corrosion and does not leach harmful substances. A polyester non-woven fabric 16 is bonded and fixedly installed on the inner side of the antifouling membrane 15. The polyester non-woven fabric is made of high-strength polyester non-woven fabric, which has high tensile strength, uniform pores, and can be repeatedly washed and reused.

[0031] This allows wastewater to enter the filter cylinder 14 through the inlet pipe 12, and then pass through the polyester nonwoven fabric 16 and the antifouling membrane 15 in sequence for filtration. The filtered wastewater then enters the housing 11 from inside the filter cylinder 14 and is then output through the outlet pipe 13. The filtered impurities remain inside the polyester nonwoven fabric 16.

[0032] like Figure 3As shown, in a preferred embodiment, the cleaning agent delivery mechanism 2 includes a rotating tube 21 rotatably nested within the center of the filter cylinder 14 via a bearing. A first sealing element (not shown) is provided between the rotating tube 21 and the filter cylinder 14 to prevent wastewater inside the filter cylinder 14 from flowing out through the gap between the output shaft of the servo motor 22 and the filter cylinder 14. The bottom end of the rotating tube 21 is connected to a servo motor 22 fixedly disposed at the bottom of the filter cylinder 14. A waterproof cover (not shown) is sleeved on the outside of the servo motor 22 and fixedly disposed at the bottom of the filter cylinder 14 to prevent the servo motor 22 from being short-circuited and damaged due to immersion in wastewater. The power supply wire of 2 passes through the waterproof cover and extends to the outside of the housing 11. A second sealing element (not shown) is provided between the power supply wire and the waterproof cover to prevent sewage from entering the interior of the waterproof cover. The top of the outer side of the rotating pipe 21 is fitted with a fixed bracket 23 that is fixedly installed inside the water inlet pipe 12 through a bearing to stabilize the rotating pipe 21 and prevent it from shaking due to centrifugal force when it revolves, thus ensuring the stability of the movement trajectory of the branch pipe 31 and the hollow turntable 32. The top of the rotating pipe 21 is rotatably connected to an inlet pipe 24 that is fixedly installed through the side of the water inlet pipe 12 through a rotary joint. A booster pump 25 that is fixedly installed on the top of the housing 11 is installed on the inlet pipe 24.

[0033] Therefore, when it is necessary to clean the inside of the polyester nonwoven fabric 16, the booster pump 25 inputs the cleaning fluid into the rotating tube 21 through the inlet pipe 24, and then the rotating tube 21 inputs the cleaning fluid into multiple branch pipes 31. During this process, the servo motor 22, after being powered on, drives the rotating tube 21 to rotate continuously.

[0034] It should be noted that a drain pipe (not shown) extending to the outside of the housing 11 is fixedly installed through the bottom back of the filter cylinder 14. A drain valve is installed on the drain pipe so that after the cleaning fluid is rinsed, the drain valve can be opened and the impurities washed off can be output through the drain pipe.

[0035] like Figure 3 As shown in this disclosure, any set of rotating cleaning components 3 includes a branch pipe 31 fixedly disposed through the outside of the rotating pipe 21. A hollow turntable 32 is rotatably sleeved at the outer end of the branch pipe 31 away from the rotating pipe 21 via a bearing. A plurality of cleaning holes 33 are evenly opened on the side of the hollow turntable 32 away from the branch pipe 31. Four push pipes 34 are evenly fixedly disposed through the outer side of the hollow turntable 32. The four push pipes 34 are evenly distributed around the circumference of the hollow turntable 32 and form a 15° angle with the tangent direction of the hollow turntable 32. This angle can maximize the reaction force of the cleaning agent spray. The spray direction is opposite to the rotation direction of the hollow turntable 32.

[0036] Thus, the cleaning agent entering the rotating tube 21 enters the interior of multiple hollow turntables 32 through multiple branch tubes 31, and is then sprayed onto the inner side of the polyester nonwoven fabric 16 through multiple cleaning holes 33. During this process, the servo motor 22 drives multiple sets of rotating cleaning components 3 to revolve through the rotating tube 21. At the same time, the cleaning agent is also sprayed out from multiple push tubes 34 on the outside of the hollow turntables 32. At this time, due to the pushing effect of the cleaning agent spraying out, the hollow turntables 32 revolve while driving the multiple cleaning holes 33 to rotate around the branch tubes 31 as the axis. Compared with the prior art, this utility model can avoid the situation of cleaning dead corners due to the gap between two adjacent nozzles, and the actual cleaning effect is better. It can effectively reduce the residue of impurities. In addition, it can be achieved by only using the pushing force of the cleaning liquid spraying out, without the need to set up additional driving components.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
