Description

Technical Field

[0001] This utility model relates to the field of boiler water quality testing technology, and in particular to a pretreatment device for boiler water quality testing. Background Technology

[0002] Pretreatment devices for boiler water quality testing are mainly used to remove interfering substances from water samples and adjust water quality parameters to ensure the accuracy and stability of subsequent testing.

[0003] A pretreatment device for boiler water quality testing disclosed in Chinese Patent Publication No. CN218212267U filters impurities from boiler water entering a connecting pipe using multiple filter plates. The boiler water can then be discharged by opening a rubber stopper, resulting in impurity-free boiler water, which improves the accuracy of subsequent testing. However, based on water quality testing pretreatment devices and existing technologies in related fields, traditional pretreatment devices often use a single filter component or multiple filter plates. In high-impurity water, the filter screens clog frequently, requiring periodic shutdowns for backwashing or replacement. This leads to interruptions in boiler water quality testing and affects the continuity of online monitoring data. Utility Model Content

[0005] The purpose of this utility model is achieved through the following technical solution: a pretreatment device for boiler water quality testing, including a mounting frame, a rotating component rotatably mounted inside the mounting frame, multiple mounting holes equally spaced on the rotating component, and a filter assembly fixedly mounted inside each mounting hole; the mounting frame includes a base plate and a top plate, multiple support columns fixedly mounted on the top of the base plate, a lead screw fixedly mounted on the top of each support column, and a first insertion hole corresponding to each lead screw on the top plate, with a nut threadedly connected to the lead screw at the top of the top plate; an inlet pipe corresponding to one of the mounting holes on the top plate, an outlet structure corresponding to the inlet pipe on the bottom plate, multiple backflushing pipes corresponding to another mounting hole on the top plate, and an operating hole corresponding to the backflushing pipes on the bottom plate; boiler water enters the filter assembly through the inlet pipe, and then the filtered boiler water enters the mounting hole and is discharged through the outlet structure; the bottom of the filter assembly is provided with a sealing component for compression deformation when it rotates with the rotating component.

[0006] Preferably, the filter assembly includes a first internally threaded sleeve, the bottom of which is fixedly provided with a filter cylinder, and the inner wall of the filter cylinder is provided with an elastic element.

[0007] Preferably, the sealing assembly includes a second internally threaded sleeve fixedly installed at the bottom of the filter cylinder, and the internal thread of the second internally threaded sleeve is connected to a sealing cap.

[0008] Preferably, the elastic element is a spring, and the elastic element is fixedly installed between the first internal threaded sleeve and the second internal threaded sleeve.

[0026] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0027] like Figures 1 to 10 As shown, a pretreatment device for boiler water quality testing includes a mounting frame 1. A rotating component 2 is rotatably mounted inside the mounting frame 1. Multiple mounting holes 21 are evenly spaced on the rotating component 2, and a filter assembly 3 is fixedly installed inside each mounting hole 21. The mounting frame 1 includes a base plate 11 and a top plate 12. Multiple support columns 13 are fixedly mounted on the top of the base plate 11, and a lead screw 14 is fixedly mounted on the top of each support column 13. A first insertion hole 121 is provided on the top plate 12 corresponding to the position of each lead screw 14. A nut 15 is threadedly connected to the top of the lead screw 14 on the top of the top plate 12. Figures 8 to 10 As shown, a fixing rod 112 is fixedly provided at the center of the base plate 11, and a second insertion hole 24 adapted to the fixing rod 112 is provided at the center of the rotating part 2. By using the fixing rod 112, the rotating part 2 can be inserted and matched with the fixing rod 112 during assembly. Then, the stability of the rotating part 2 during rotation can be ensured through the second insertion hole 24. A water inlet pipe 122 is provided at the position of one of the mounting holes 21 on the top plate 12, and a water outlet structure 4 is provided at the position of the water inlet pipe 122 on the bottom plate 11. Multiple backflush pipes 123 are provided at the position of the other mounting hole 21 on the top plate 12, and an operation hole 111 is provided at the position of the backflush pipe 123 on the bottom plate 11. Boiler water enters the filter assembly 3 through the water inlet pipe 122, and then the filtered boiler water enters the mounting hole 21 and is discharged through the water outlet structure 4. A sealing assembly 5 is provided at the bottom of the filter assembly 3 for compression deformation when it rotates with the rotating part 2.

[0028] In summary, such as Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, multiple filter components 3 are used in an alternating working mode. When one set of filter components 3 is filtering, another set is backwashing simultaneously. The filter component 3 rotated to the operation port 111 can be directly backwashed, discharged, or replaced without disassembling the entire device. At the same time, the other components are in a state of waiting to be filtered. With the fixed layout of the water inlet pipe 122 and the backwash pipe 123, the working state can be switched in a short time, improving the overall water treatment efficiency and avoiding the downtime problem caused by backwashing in traditional single filter cartridge equipment.

[0029] like Figures 2 to 7As shown, the bottom end of the second internal threaded sleeve 51 is formed with a chamfered surface. The water outlet structure 4 includes a conical water outlet hole 41 opened on the base plate 11. A water outlet pipe 42 is fixedly provided on the base plate 11 below the conical water outlet hole 41. The side with the larger diameter of the conical water outlet hole 41 is set upward. The diameter of the operating hole 111 is smaller than the upper diameter of the conical water outlet hole 41. The second internal threaded sleeve 51 is in contact with the inner wall of the operating hole 111. Boiler water is injected into the filter cylinder 32 through the water inlet pipe 122. Then the filter cylinder 32 filters the boiler water, so that impurities are left inside the filter cylinder 32. Water flows from the filter cylinder 32 into the mounting hole 21. Then the water inside the mounting hole 21 can flow into the water outlet pipe 42 through the conical water outlet hole 41, thereby discharging the filtered boiler water through the water outlet pipe 42, thus ensuring the accuracy and stability of subsequent boiler water testing.

[0030] like Figures 2 to 8 As shown, the filter assembly 3 includes a first internally threaded sleeve 31, with a filter cylinder 32 (made of flexible material, such as a polyester fiber filter screen; this is used as an example only and no specific structural limitation is imposed) fixedly mounted at the bottom of the first internally threaded sleeve 31. An elastic element 33 is provided on the inner wall of the filter cylinder 32. An externally threaded sleeve 22 is fixedly mounted at the position of the mounting hole 21 corresponding to the position of the first internally threaded sleeve 31. The first internally threaded sleeve 31 and the externally threaded sleeve 22 are threadedly connected. Multiple backflush holes 23, which cooperate with the backflush pipe 123, are evenly spaced on the externally threaded sleeve 22. The sealing assembly 5 includes a second internally threaded sleeve 51 fixedly mounted at the bottom of the filter cylinder 32. A sealing cap 52 is threadedly connected to the inside of the second internally threaded sleeve 51. The elastic element 33 is a spring, fixedly mounted between the first internally threaded sleeve 31 and the second internally threaded sleeve 51. By rotating the rotating component 2, the positions of multiple filter assemblies 3 can be switched. When the chamfered surface of the second internal threaded sleeve 51 contacts the conical water outlet 41, the second internal threaded sleeve 51 can cause the filter cylinder 32 and the elastic element 33 to contract, thereby causing the filter cylinder 32 and the elastic element 33 to deform. The filter cylinder 32 deforms and squeezes out the fine impurities in the mesh through physical extrusion, and breaks up the dirt clumps on the surface. When the filter cylinder 32 that needs to be cleaned corresponds to the operating hole 111, the elastic force of the elastic element 33 quickly recovers, thereby causing the second internal threaded sleeve 51 to enter the operating hole 111, forming an extension and shaking of the filter cylinder 32, further improving the effect of clogging. Then the sealing cap 52 can be removed, and then clean water is injected into the mounting hole 21 through multiple backflush pipes 123. Then the clean water inside the mounting hole 21 can flow from the outside of the filter cylinder 32 into the inside, thereby forming a backflush on the filter cylinder 32, and thus the impurities and dirt are concentrated and discharged through the opening of the second internal threaded sleeve 51.

[0031] In summary, such as Figure 4 , Figure 5 and Figure 7As shown, when the filter assembly 3 rotates and switches, the filter cylinder 32 automatically contracts, causing the filter cylinder 32 to undergo elastic deformation. Through mechanical stress, particulate impurities in the mesh are squeezed out and the clumps attached to the surface are broken. By using a physical peeling mechanism combined with reverse water flow rinsing, the backwashing effect can be improved, solving the problem of deep clogging of traditional filter screens.

[0032] The work process is as follows:

[0033] S1: When in use, boiler water is injected into the filter cylinder 32 through the inlet pipe 122. The filter cylinder 32 then filters the boiler water, leaving impurities inside the filter cylinder 32. Water flows from the filter cylinder 32 into the mounting hole 21. The water inside the mounting hole 21 then flows into the outlet pipe 42 through the conical outlet hole 41, thereby discharging the filtered boiler water through the outlet pipe 42, thus ensuring the accuracy and stability of subsequent boiler water testing.

[0034] S2: When it is necessary to clean the filter cylinder 32, the rotating part 2 is rotated to switch the position of multiple filter components 3. When the chamfered surface of the second internal thread sleeve 51 contacts the conical water outlet hole 41, the second internal thread sleeve 51 can cause the filter cylinder 32 and the elastic element 33 to contract, thereby allowing the filter cylinder 32 and the elastic element 33 to deform.

[0035] S3: The filter cartridge 32 deforms, squeezing out the fine impurities inside the mesh through physical compression and breaking up the dirt that has clumped on the surface;

[0036] S4: When the filter cylinder 32 that needs to be cleaned corresponds to the operating hole 111, the elastic force of the elastic element 33 is quickly restored, thereby causing the second internal thread sleeve 51 to enter the operating hole 111, forming an extension and shaking of the filter cylinder 32, further improving the effect of removing the clumps. Then the sealing cover 52 can be removed, and then clean water is injected into the mounting hole 21 through multiple backflush pipes 123. Then the clean water inside the mounting hole 21 can flow from the outside of the filter cylinder 32 into the inside, thereby forming a backflush of the filter cylinder 32, thereby concentrating and discharging impurities and dirt through the opening of the second internal thread sleeve 51.

[0037] S5: When the rotating part 2 rotates, another filter assembly 3 will cooperate with the water inlet pipe 122 and the water outlet structure 4 to continuously perform filtration.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
