Technical Field

[0001] This utility model relates to the field of circulating water treatment technology, and in particular to a three-way filtration device. Background Technology

[0002] In modern industrial production processes, various types of industrial waste gases are typically generated. To meet increasingly stringent environmental emission standards, factories and enterprises generally employ specialized waste gas treatment equipment for centralized purification. During the operation of these equipment, a water circulation system or spray system is usually installed to cool and wash away dust from the high-temperature waste gases. To conserve water resources, this cooling and washing water is usually recycled.

[0003] However, in practical applications, existing water treatment pipelines and devices have the following significant drawbacks: First, traditional tees do not have a filtration function. The filtration function usually needs to be implemented by a separate component, which results in additional occupation of valuable installation space inside the equipment, making the equipment bulky.

[0004] Secondly, existing technologies combine the filter structure with the tee, but due to the complex or unreasonable design of the structure, the filter structure is either not securely fixed and is easy to fall off, causing filter failure and clogging of subsequent nozzles; or the disassembly and replacement of the filter structure is very cumbersome, and when the filter structure is clogged and needs cleaning and maintenance, the operation is time-consuming and laborious, which seriously affects the continuous operating efficiency of the equipment.

[0005] Therefore, there is an urgent need to develop a compact, easy-to-maintain, and less prone-to-failure three-way filtration device to overcome the above-mentioned defects. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] The following is combined with Figures 1-2This invention describes a three-pass filtration device according to an embodiment of the present invention.

[0023] like Figure 1-2 As shown, this utility model embodiment provides a three-way filtration device, including a three-way body, the three-way body including a first tube 1 and a second tube 2 communicating with the middle of the first tube 1; the two ends of the first tube 1 are respectively the water inlet 11 and the first water outlet 12, and the end of the second tube 2 away from the first tube 1 is the second water outlet 21; it also includes: a filter section 3, which is detachably disposed inside the first tube 1, and the water filtered by the filter section 3 enters the second tube 2.

[0024] It should be understood that in this embodiment, the filter unit 3 is disposed in the first pipe body 1, so that the water to be filtered enters the second pipe through the filtration of the filter unit 3 and flows out through the second water outlet 21 for use. No additional filtration equipment is required, the integration is high, and the space occupancy rate is reduced. When the filtration effect of the filter unit 3 drops to the point that it cannot be used normally, the sewage can be discharged through the first water outlet 12 for sewage discharge and to avoid blockage. Since the filter unit 3 is detachably connected to the first pipe body 1, it can be easily removed when it needs to be cleaned, which is convenient for disassembly and assembly and easy for maintenance.

[0025] In some possible implementations, the filter section 3 may be a filter element of the mesh type. The filter section 3 is cylindrical with openings at both ends, which are the inlet side and the outlet side, respectively. The sidewall of the filter section 3 has a filter mesh structure. Impurities with a particle size larger than the mesh size of the filter mesh cannot pass through the filter mesh and therefore cannot enter the second pipe through the filter side, thereby realizing the filtration function of the three-way filter device for sewage. When the filtration function of the filter section 3 decreases or filtration is not required, the sewage can also be directly discharged from the first outlet end 12, realizing the sewage discharge function of the three-way filter device.

[0026] like Figure 2 As shown, a three-way filter device provided according to an embodiment of the present utility model further includes: a water inlet pipe 4, disposed at the water inlet end 11, and at least a portion of the water inlet pipe 4 is inserted into the interior of the first pipe body 1.

[0027] In some possible implementations, the water inlet pipe 4 is inserted into the first pipe body 1 and welded or bonded to the first pipe body 1.

[0028] like Figure 2 As shown, according to an embodiment of the present invention, a three-way filter device is provided, wherein a limiting protrusion 41 is formed circumferentially on the inner wall of the water inlet pipe 4, which is suitable for engaging with the end of the filter section 3 near the water inlet 11; it also includes: a first core 5, which is a hollow structure, the first core 5 is disposed inside the first water outlet 12, and the first core 5 forms a limiting groove 51, which is suitable for engaging with the end of the filter section 3 near the first water outlet 12.

[0029] In some possible implementations, both ends of the water inlet pipe 4 are wide openings, and the middle part of the water inlet pipe 4 forms a narrow opening due to the setting of the limiting protrusion 41 (the inner diameter of the water inlet pipe 4 at this point is smaller than the inner diameter of the two ends of the water inlet pipe 4). Since the outer diameter of the filter part 3 is small, the narrow opening here can be engaged with the outer wall of the filter part 3 to form a mating relationship; the limiting protrusion 41 can be a continuous trapezoidal platform structure circumferentially set on the inner wall of the water inlet pipe 4, and the top surface of the trapezoidal platform abuts against the outer wall surface of the filter part 3.

[0030] In some possible implementations, the first core 5 is bonded to the inner wall of the first water outlet 12 to fix the tail end of the filter section 3, and the inner diameter of the internal through hole of the first core 5 is smaller than the inner diameter of the first water outlet 12.

[0031] like Figure 2 As shown, according to an embodiment of the present invention, a three-way filter device is provided, wherein a first sealing ring 31 is provided circumferentially on the outer wall of one end of the filter part 3, and a second sealing ring 32 is provided circumferentially on the outer wall of the other end of the filter part 3; a snap-fit ​​groove 411 is formed circumferentially on the limiting protrusion 41, which is suitable for abutting against the first sealing ring 31; and the second sealing ring 32 abuts against the side wall of the limiting groove 51.

[0032] It should be understood that the snap-fit ​​groove 411 is formed on the top surface of the limiting protrusion 41, creating a tapered structure from the filter section 3 toward the water inlet 11. After the filter section 3 is installed in place, the first sealing ring 31 abuts tightly against the snap-fit ​​groove 411, and the second sealing ring 32 abuts tightly against the side wall of the limiting groove 51, thus achieving a firm fixation. This is to prevent the filter section 3 from moving within the first tube 1 due to water flow impact or water pressure changes during the operation of the three-way filter device, which could lead to filter failure and serious nozzle blockage.

[0033] like Figure 2 As shown, according to an embodiment of the present invention, a three-way filter device is provided in which the opening of the limiting groove 51 gradually expands from one side of the first water outlet 12 to one side of the water inlet 11.

[0034] It should be understood that the groove of the limiting groove 51 is gradually widened and has the shape of a trumpet, which can naturally form a guiding effect and guide the filter part 3 during installation, making the installation process of the filter part 3 smoother and more convenient.

[0035] like Figure 2 As shown, a three-way filter device provided according to an embodiment of the present utility model further includes: a first water outlet pipe 6, disposed at the first water outlet end 12, and at least a portion of the first water outlet pipe 6 is inserted into the interior of the first core 5.

[0036] In some possible implementations, the first water outlet pipe 6 is inserted into the interior of the first core 5 and bonded to the first core 5. The inner diameter of the first water outlet pipe 6 is not less than the inner diameter of the through hole inside the first core 5. At least a portion of the first water outlet pipe 6 extends out of the first core 5 to facilitate connection to other pipes or mechanisms.

[0037] like Figure 1-2 The three-way filtration device provided according to an embodiment of the present utility model is shown, wherein the inner diameter of the first outlet pipe 6 is smaller than the inner diameter of the inlet pipe 4.

[0038] It should be understood that since the three-way filter device has only one inlet end 11 and two outlet ends, the inner diameter of the inlet pipe 4 is larger than the inner diameter of the first outlet pipe 6, ensuring that the water inlet volume of the inlet end 11 is greater than the water outlet volume of any one of the outlet ends, which is a scientific and reasonable design. The inner diameter of the inlet pipe 4 is larger than the inner diameter of the first outlet pipe 6, so that when discharging sewage, the water flow speed can gradually increase along the axial direction of the first pipe body 1, and the water pressure can gradually increase, which facilitates the rapid discharge of sewage and can also flush down the impurities attached to the filter section 3, preventing impurities from accumulating in the pipe body.

[0039] like Figure 2 As shown, a three-way filter device provided according to an embodiment of the present invention further includes: a second water outlet pipe 7, which is disposed at the second water outlet end 21.

[0040] In some possible implementations, the second water outlet pipe 7 is bonded or welded to the second water outlet end 21, and at least a portion of the second water outlet pipe 7 extends beyond the second water outlet end 21 to facilitate connection to other pipes or mechanisms.

[0041] like Figure 2 As shown, a three-way filter device provided according to an embodiment of the present invention further includes: a second core 8, which is a hollow structure, and the second core 8 is disposed inside the second water outlet 21; wherein at least a portion of the second water outlet pipe 7 is inserted into the interior of the second core 8.

[0042] It should be understood that the second core 8 can be glued and fixed inside the second water outlet 21; the second core 8 is to match the size of the second water outlet 21 and the second water outlet pipe 7. If the size of the second water outlet pipe 7 matches that of the second water outlet 21, then the second core 8 is not needed.

[0043] like Figure 1-2 As shown, a three-way filter device provided according to an embodiment of the present utility model further includes: a flexible joint 9, which is disposed in the inlet pipe 4, the first outlet pipe 6 and the second outlet pipe 7.

[0044] It should be understood that the fittings 9 at the ends of the inlet pipe 4, the first outlet pipe 6, and the second outlet pipe 7 facilitate the connection to other pipes or mechanisms, and also facilitate the installation, disassembly, and maintenance of the three-way filter device.

[0045] In some other embodiments of this utility model, a sensor and a valve body can be installed on the first water outlet pipe 6, and the opening and closing of the valve body can be controlled by a controller. The sensor measures the pressure inside the pipe. If the pressure exceeds a preset pressure threshold, the filter section 3 may be blocked. At this time, the valve body is controlled to open so that water can be discharged from the first water outlet pipe 6. Specifically, if the pressure reaches the first preset pressure threshold, the valve body is controlled to open at a first preset time interval and close after a second preset time interval. If the pressure reaches the second preset pressure threshold, the valve body is controlled to remain open, thereby ensuring the normal use of the three-way filter device.

[0046] In a specific embodiment of this utility model, the three-way filter device is used as follows: Installation: Attach the inlet pipe 4, the first core 5, and the second core 8 to the inlet end 11, the first outlet end 12, and the second outlet end 21, respectively; insert the first outlet pipe 6 into the first core 5 and attach it securely; insert the second outlet pipe 7 into the second core 8 and attach it securely; insert the filter part 3 into the first pipe body 1 along the inlet pipe 4 until the first sealing ring 31 of the filter part 3 engages and is securely fastened to the snap-fit ​​groove 411, and the second sealing ring 32 engages and is securely fastened to the limiting groove 51; install the union 9 at the end of the inlet pipe 4, the end of the first outlet pipe 6, and the end of the second outlet pipe 7, respectively.

[0047] Maintenance: If the filtration function of the filter section 3 is significantly reduced or blocked, maintenance should be performed. First, disconnect the union 9 at the end of the inlet pipe 4, the end of the first outlet pipe 6, and the end of the second outlet pipe 7. Then, use tweezers or clamps to pull the filter section 3 out of the inlet pipe 4. After pulling out the filter section 3, a new filter section 3 can be replaced or the filter section 3 can be cleaned.

[0048] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model 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 of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
