Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filtration and separation technology, specifically relating to an integrated device for an automatic turbine backwashing filter. Background Technology
[0002] A self-cleaning filter is a device that can automatically separate and filter impurities in a fluid under specific conditions (such as when the pressure drop reaches a preset value) and achieve self-cleaning in a certain way. It consists of three main parts: two vertical containers, an actuator, and a programmable controller.
[0003] Currently, in the cleaning process of commonly available automatic backwash filters, when the inlet and outlet pressure difference reaches a preset value, the control program will open and close relevant valves according to a predetermined process to switch filters. The switched-off filters are cleaned by the combined action of external backwash nitrogen, high-temperature steam and soaking media (such as clean aviation kerosene, diesel or a certain chemical cleaning agent). However, the backwash nitrogen, high-temperature steam and soaking media used often contain impurities or contaminants. After cleaning the filter element, these substances mix with the impurities of the cleaned filter element to form a relatively turbid medium. This cleaned medium should not be directly returned to the original fluid system to avoid secondary pollution. Therefore, the cleaned medium is discharged into the waste liquid tank, but this also leads to a large waste of resources. Utility Model Content
[0004] The purpose of this invention is to provide an integrated device for automatic turbine backwashing filter, which can automatically perform backwashing to ensure that the filter is unobstructed for a long period of time. This prevents the backwash liquid carrying impurities from being discharged into the sewage tank as waste liquid, but instead allows it to be recycled, achieving zero discharge.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] An integrated automatic turbine backwashing filter device includes a support frame. Two automatic turbine filters are fixedly mounted on the top of the support frame. The inlet ends of the two automatic turbine filters are connected to inlet pipes, and the outlet ends of the two automatic turbine filters are connected to outlet pipes. One end of each automatic turbine filter is connected to a first delivery pipe. The end of the first delivery pipe away from the automatic turbine filters is connected to a dual filter. The bottom of the dual filter is connected to a liquid storage and sedimentation tank. A circulating pump is fixedly mounted on the casing of one side of the liquid storage and sedimentation tank, and the inlet end of the circulating pump is fixedly connected to... On the liquid storage and settling tank, the outlet of the circulating pump is connected to a second delivery pipe, and one end of the second delivery pipe is connected to the inlet pipe. A discharge pipe is connected to the bottom of one side of the liquid storage and settling tank. Several shut-off valves are fixedly installed on the surfaces of the inlet pipe, the discharge pipe, the second delivery pipe, and the discharge pipe. Liquid level detection instruments are fixedly installed on the surfaces of the inlet pipe, the discharge pipe, the first delivery pipe, and the second delivery pipe. A ball valve is fixedly installed on the surface of each first delivery pipe. An intelligent operating cabinet is fixedly installed on one side of the top of the support frame and is electrically connected to the liquid storage and settling tank.
[0007] Preferably, the housing of the turbine automatic filter is made of castings, steel, or stainless steel welded parts.
[0008] Preferably, the housing of the dual filter surface is a welded component made of steel or stainless steel material and manufactured through a welding process.
[0009] Preferably, the inner side of the dual filter is equipped with a filter element, and different types of filter elements such as basket type, bag type, and candle type are used for filtration.
[0010] Preferably, the surface of the liquid storage and sedimentation tank is made of stainless steel.
[0011] Preferably, the liquid storage sedimentation tank has a built-in labyrinth baffle, gravity separation chamber, separation element, and movable partition.
[0012] Preferably, the liquid storage and sedimentation cabinet has a built-in heating coil, which is a heat-resistant coil made of high-density polyethylene or polypropylene.
[0013] The technical effects achieved by this utility model are as follows:
[0014] This utility model discloses an integrated automatic turbine backwashing filter device. Through the coordinated operation of an automatic turbine filter, a dual filter, a liquid storage and settling tank, and a second delivery pipe, the impeller module built into the inlet of the automatic turbine filter continuously draws the kinetic energy of the liquid medium to be filtered from the inlet pipe, driving the internal backwashing device of the automatic turbine filter to operate. This facilitates continuous backwashing of each internal candle filter element through the internal and external pressure difference. The backwash liquid is discharged through the first delivery pipe and enters the dual filter for secondary filtration. The filtered backwash liquid flows from the outlet of the dual filter into the lower liquid storage and settling tank, passing through a labyrinthine baffle and a gravity separation chamber. Through the layered action of the separation elements, impurities settle at the bottom of the liquid storage settling tank for easy cleaning. When the liquid level detection instrument detects that the liquid level has reached the set value, the intelligent control cabinet automatically starts the circulation pump. The backwash liquid, which has undergone secondary filtration and static sedimentation, is then pumped into the inlet of the inlet pipe and used as a regular filter medium to enter the turbine automatic filter for precision filtration. This achieves the goal of zero discharge from backwashing through automatic filtration. The device can automatically perform backwashing to ensure that the long-cycle filter is unobstructed, preventing the backwash liquid carrying impurities from being discharged as waste liquid into the sewage tank. Instead, it continues to be recycled, achieving zero discharge. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0021] like Figure 1 - Figure 3As shown, an integrated turbine automatic backwashing filter device includes a support frame 1. Two turbine automatic filters 2 are fixedly installed on the top of the support frame 1. The inlet ends of the two turbine automatic filters 2 are connected to inlet pipes 3, and the outlet ends of the two turbine automatic filters 2 are connected to drain pipes 4. One end of the two turbine automatic filters 2 is connected to a first delivery pipe 5. The end of the first delivery pipe 5 away from the turbine automatic filters 2 is connected to a dual filter 6. The bottom of the dual filter 6 is connected to a liquid storage and settling tank 7. A circulation pump 8 is fixedly installed on the casing on one side of the liquid storage and settling tank 7, and the inlet end of the circulation pump 8 is fixedly connected to the liquid storage and settling tank. On the 7, the outlet end of the circulating pump 8 is connected to the second conveying pipe 9, and one end of the second conveying pipe 9 is connected to the inlet pipe 3. The bottom of one side of the liquid storage sedimentation tank 7 is connected to the discharge pipe 10. Several shut-off valves 11 are fixedly installed on the surface of the inlet pipe 3, the discharge pipe 4, the second conveying pipe 9 and the discharge pipe 10. Liquid level detection instruments 12 are fixedly installed on the surface of the inlet pipe 3, the discharge pipe 4, the first conveying pipe 5 and the second conveying pipe 9. A ball valve 13 is fixedly installed on the surface of each first conveying pipe 5. An intelligent operation cabinet 14 is fixedly installed on one side of the top of the support frame 1 and is electrically connected to the liquid storage sedimentation tank 7.
[0022] The support frame 1 supports the entire device. The impeller module built into the inlet of the turbine automatic filter 2 continuously draws the kinetic energy of the filter liquid medium in the inlet pipe 3, driving the backwashing device inside the turbine automatic filter 2 to work. Through the internal and external pressure difference, the internal candle filter element is continuously backwashed one by one. The backwash liquid is discharged from the first delivery pipe 5 and enters the double filter 6 for secondary filtration. The filtered backwash liquid flows from the outlet of the double filter 6 into the liquid storage and sedimentation tank 7 below. After passing through the labyrinth baffle, gravity separation chamber and separation elements, the impurities settle at the bottom of the liquid storage and sedimentation tank 7, which can be cleaned periodically. When the liquid level detection instrument 12 detects that the liquid level has reached the set value, the circulation pump 8 is automatically started through the intelligent operation cabinet 14. The backwash liquid after secondary filtration and static sedimentation is input into the inlet of the inlet pipe 3 through the circulation pump 8. As the regular filter medium, it enters the turbine automatic filter 2 again through the inlet pipe 3 for precision filtration, so as to achieve automatic filtration and achieve the goal of zero discharge of backwashing.
[0023] Only after the liquid has been filtered through the precision filter element of the turbine automatic filter 2 can the clean liquid flow out from the drain pipe 4. When the liquid level slowly drops to the set low level, the circulation pump 8 will stop automatically. If the circulation pump 8 system fails, the backwash liquid of the liquid storage sedimentation tank 7 can still flow into the underground tank through the discharge pipe 10 to ensure the safe operation of the online system.
[0024] The design of various valves, such as the shut-off valve 11, the liquid level detection instrument 12, and the ball valve 13, allows staff to flexibly adjust the filtration process according to actual needs. The shut-off valve 11 can be used to control the flow direction of the backwash liquid, ensuring that it can accurately enter the designated processing stage when needed.
[0025] The liquid level sensor in the liquid level detection instrument 12 accurately monitors the liquid position, providing key data support for automated control and enhancing the adaptability and flexibility of the entire device.
[0026] like Figure 1 As shown, the housing of the turbine automatic filter 2 is made of castings, steel, and stainless steel welded parts.
[0027] Specifically, the housing of the turbine automatic filter 2 is made of castings, steel, and stainless steel welded parts, which ensures that the turbine automatic filter 2 is sturdy and durable and can withstand high working pressure and harsh working environment. The use of castings gives the housing high strength and rigidity, and can withstand greater impact force.
[0028] Steel materials offer excellent corrosion resistance and wear resistance, extending the service life of the equipment; while the application of stainless steel welded parts not only enhances the overall structural strength of the shell, but also avoids leakage problems caused by corrosion, ensuring the sealing and filtration effect of the equipment.
[0029] like Figure 1 As shown, the housing of the dual filter 6 is a welded component made of steel or stainless steel through a welding process.
[0030] The shell of the dual filter 6 is designed with steel or stainless steel, which has sufficient strength and rigidity to withstand various stresses and pressures during operation, and has good resistance to corrosion and wear, thus ensuring the stability and reliability of the dual filter 6 during long-term use.
[0031] The application of welding technology further enhances the overall structural strength of the shell;
[0032] The choice of steel or stainless steel materials also avoids leakage problems caused by corrosion, ensuring the sealing and filtration effect of the dual filter 6, thereby improving the working efficiency and performance of the entire device.
[0033] like Figure 3 As shown, the inner side of the dual filter 6 is equipped with filter elements, which are of different types such as mesh basket type, bag type, and candle type for filtration.
[0034] Specifically, the dual filter 6 has two independent filtration chambers, each with a filter element installed. This design allows the other chamber to continue operating normally while the filter element in one chamber is being backwashed or maintained, thus ensuring continuous operation and filtration efficiency of the filter.
[0035] Different types of filter cartridges can be selected according to actual filtration needs to meet the requirements of different media and filtration precision, thus enhancing the adaptability and flexibility of the equipment.
[0036] like Figure 2 As shown, the surface of the liquid storage sedimentation tank 7 is made of stainless steel.
[0037] The surface of the liquid storage sedimentation tank 7 is made of stainless steel, which ensures the strength and rigidity of the liquid storage sedimentation tank 7, improves its corrosion resistance and wear resistance, and enables it to maintain long-term stability and reliability in harsh working environments.
[0038] The liquid storage and sedimentation tank 7 is designed with full consideration of the needs of liquid storage and sedimentation, which can effectively promote the sedimentation and separation of liquids and improve the purity and processing efficiency of liquids.
[0039] like Figure 1 As shown, the liquid storage and sedimentation tank 7 is equipped with a labyrinth baffle, a gravity separation chamber, separation elements, and movable partitions.
[0040] Specifically, the labyrinthine baffle design can guide the fluid to change its flow direction multiple times within the liquid storage and settling tank 7, increasing the contact time between the fluid and the gravity separation chamber, thereby improving the settling effect;
[0041] The gravity separation chamber uses gravity to allow heavier impurity particles to settle to the bottom naturally, while lighter clean liquid rises to the top, achieving initial liquid separation.
[0042] The separation element further refines the liquid, removing tiny particles and suspended solids to ensure high purity of the output liquid; the movable baffle can be adjusted in position according to actual needs, flexibly controlling the space size of different chambers to adapt to the needs of different media and processing volumes, enhancing the versatility and practicality of the equipment.
[0043] like Figure 1 As shown, the liquid storage and sedimentation tank 7 is equipped with a heating coil, which is made of heat-resistant high-density polyethylene or polypropylene.
[0044] The design of the heating coil not only improves the adaptability of the liquid storage and settling tank 7, enabling it to work normally in low-temperature environments and prevent liquid freezing, but also allows for heating of the liquid when necessary. The selection of high-density polyethylene or polypropylene materials ensures that the heating coil has good cold resistance and chemical stability, ensuring normal operation in winter or in cold northern regions, in accordance with process requirements.
[0045] The working principle of this utility model is as follows: First, the impeller module built into the inlet of the turbine automatic filter 2 continuously draws the flow kinetic energy of the liquid medium to be filtered, which drives the backwashing device inside the turbine automatic filter 2 to work. Through the internal and external pressure difference, the internal candle filter element is backwashed one by one. The backwash liquid after backwashing is discharged from the first conveying pipe 5 and enters the double filter 6 for secondary filtration. The filtered backwash liquid flows from the outlet of the double filter 6 into the liquid storage and sedimentation tank 7 below. After passing through the labyrinth baffle, gravity separation chamber and separation element, the impurities are settled at the bottom of the liquid storage and sedimentation tank 7.
[0046] When the liquid level detection instrument 12 detects that the liquid level has reached the set value, the intelligent operation cabinet 14 automatically starts the circulation pump 8, and inputs the backwash liquid after secondary filtration and static sedimentation into the inlet of the liquid inlet pipe 3 through the circulation pump 8 for precision filtration again, so as to achieve the zero discharge target of backwashing and complete the backwashing work.
[0047] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
