Description

Technical Field

[0001] This application relates to the field of pipeline impurity removal and filtration technology, and more specifically, to a pipeline impurity removal and filtration device. Background Technology

[0002] In northern regions, heating systems are a key infrastructure for ensuring residents stay warm during winter. However, the water in heating pipes is not pure. Over time, the metal components inside the pipes rust and corrode, producing new debris. If left untreated, impurities will gradually accumulate, not only reducing heat transfer efficiency and significantly diminishing the indoor heating effect, but also potentially clogging pipes, causing heating malfunctions, or even damaging heating equipment. Therefore, impurity removal and filtration devices for heating pipes are of paramount importance.

[0003] In the field of filtration for heating pipes, external filters are typically used to filter the water entering the heating pipes. Currently, straight-through filters are commonly used due to their simple structure and minimal obstruction to water flow, making them widely applicable. In traditional straight-through filters, water rushes in from above the inlet. As it flows through the internal filter cartridge, impurities and rust are trapped, and the purified water is discharged from the outlet below. However, in practice, this has revealed many problems. Due to gravity, a large amount of water rushes rapidly to the bottom of the filter cartridge, instantly increasing the water pressure at the bottom. Rust accumulates at this point much faster than at the top. As the blockage at the bottom worsens, the water slowly flows upward through the upper filter cartridge, resulting in the upper filtration section not being fully utilized. When replacing the filter cartridge, it is found that the upper area still retains considerable filtration capacity, greatly reducing the overall utilization rate of the filter cartridge, wasting resources and affecting filtration efficiency. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application provides a pipeline impurity removal and filtration device, which has the advantage of high filtration and impurity removal efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a pipeline impurity removal and filtration device, comprising a tank, an inlet fixedly installed on the top of the tank, a base installed on the bottom side of the tank, an outlet fixedly installed through the base, a filtration and impurity removal assembly fixedly installed on the top of the base, the filtration and impurity removal assembly comprising a filter cylinder fixedly installed on the top of the base and located inside the tank, a winding guide groove fixedly installed on the outer surface of the filter cylinder, the winding guide groove being coiled and tightly attached to the inner wall of the tank, a guide slot being opened inside the winding guide groove, and the top of the outlet communicating with the inside of the filter cylinder.

[0006] As a preferred technical solution of this application, a sealing assembly is movably installed at the connection between the tank and the base. The sealing assembly includes a first C-shaped retaining ring and a second C-shaped retaining ring movably installed on both sides of the contact point between the tank and the base. One end of the first C-shaped retaining ring and the second C-shaped retaining ring are hinged together by a hinge. A fixing protrusion is fixedly installed on the outer surface of the other end of the first C-shaped retaining ring and the second C-shaped retaining ring. The two fixing protrusions are connected by a fastening assembly. An airbag is fixedly installed inside the first C-shaped retaining ring and the second C-shaped retaining ring, and the airbag is annular.

[0007] As a preferred technical solution of this application, the fastening assembly includes a bidirectional threaded rod, the internal threads of the two fixing protrusions are on the rod body of the bidirectional threaded rod in different thread directions, and the two ends of the bidirectional threaded rod pass through the fixing protrusions.

[0008] As a preferred technical solution of this application, the end of the bidirectional threaded rod is provided with a rotating block, and the radius of the rotating block is larger than the radius of the bidirectional threaded rod.

[0009] As a preferred technical solution of this application, the filter cylinder is wide at the top and narrow at the bottom, and the winding guide groove is inclined inward.

[0010] As a preferred technical solution of this application, a heat insulation sleeve is fixedly fitted onto the outer surface of the tank.

[0011] As a preferred technical solution of this application, a water outlet connecting pipe is fixedly connected to the bottom side of the base, and it is connected to the water outlet and is L-shaped.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] 1. This application utilizes the principle that hot water flows downwards along the spiraling guide channel, gradually passing through the filter cartridge for filtration and impurity removal. The specially designed guide slots allow water to flow directly into the lower spiral guide channel, preventing water from concentrating in the upper channel and passing through the filter cartridge. This ensures the filter cartridge is fully utilized. Compared to traditional devices, this device, through the unique structure of the spiral guide channel, allows hot water to flow along a specific trajectory, extending the time and speed of water flow during the spiraling process. This ensures that the water entering the filter makes full contact with the filter cartridge at the top for filtration and impurity removal. Furthermore, the clever diversion design of the guide slots prevents localized filtration overload, allowing some water to directly reach the lower part for filtration. This ensures balanced filtration loss in all areas of the filter cartridge, extending its service life, reducing maintenance costs, extending filter cartridge replacement time, reducing filter cartridge replacement frequency, and improving the overall utilization rate of the filter cartridge.

[0014] 2. When the bidirectional threaded rod rotates, it will cause the two fixed protrusions to gradually move inward, thereby causing the first C-shaped retaining ring and the second C-shaped retaining ring to gradually move inward. Then, the internal airbag will gradually fit tightly against the contact point between the tank and the base, and the airbag will be gradually compressed, causing it to expand laterally, thereby increasing the sealing effect at the contact point between the tank and the base. Compared with traditional devices, this device is simple and efficient to operate by rotating the bidirectional threaded rod. It can drive the first C-shaped retaining ring and the second C-shaped retaining ring to move closer through the fixed protrusion, causing the internal airbag to expand and fit tightly against the contact point between the tank and the base, effectively enhancing the sealing and stability of the connection.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0024] like Figures 1 to 6 As shown, the pipeline impurity removal and filtration device provided in this application includes a tank 1. An inlet 2 is fixedly installed on the top of the tank 1. A base 3 is installed on the bottom side of the tank 1. An outlet 4 is fixedly installed through the base 3. A filter and impurity removal assembly 5 is fixedly installed on the top of the base 3. The filter and impurity removal assembly 5 includes a filter cylinder 501 fixedly installed on the top of the base 3 and located inside the tank 1. A winding guide groove 502 is fixedly installed on the outer surface of the filter cylinder 501. The winding guide groove 502 is coiled and tightly attached to the inner wall of the tank 1. A guide slot 503 is opened inside the winding guide groove 502. The top of the outlet 4 is connected to the inside of the filter cylinder 501.

[0025] When the operator connects an external hot water supply pipe through inlet 2, hot water flows into the tank 1 through inlet 2. Since the top of the filter cartridge 501 is sealed, the hot water flows in from the periphery of the filter cartridge 501. Because the winding guide grooves 502 coil up and down and adhere tightly to the inner wall of the tank 1, the hot water flows downwards along the spiral trajectory of the winding guide grooves 502. Simultaneously, the water gradually passes through the filter cartridge 501 for filtration and impurity removal. Furthermore, the guide slots 503 at different vertical heights allow water to flow directly into the lower winding guide grooves 502, preventing water from concentrating in the upper winding guide grooves 502 and being filtered by the filter cartridge 501, thus ensuring that the filter cartridge 501 is fully utilized for filtration. The hot water filtered by the filter cartridge 501 flows into outlet 4 and exits from the bottom of outlet 4.

[0026] Hot water flows downwards along the spiraling guide channel 502, gradually passing through the filter cartridge 501 for filtration and impurity removal. The guide slot 503 allows water to flow directly into the lower spiral guide channel 502, preventing water from concentrating in the upper channel and passing through the filter cartridge 501. This ensures the filter cartridge 501 is fully utilized for filtration. Compared to traditional devices, this device, through the unique structure of the spiral guide channel 502, allows hot water to flow along a specific trajectory, extending the time and speed of water flow during the spiraling process. This ensures that the water entering the filter makes full contact with the filter cartridge at the top for filtration and impurity removal. Furthermore, the clever diversion design of the guide slot 503 avoids local filtration overload, allowing some water to directly reach the lower filter cartridge 501 for filtration. This ensures balanced filtration loss across all areas of the filter cartridge 501, extending its service life, reducing maintenance costs, extending filter cartridge replacement time, reducing filter cartridge replacement frequency, and improving the overall utilization rate of the filter cartridge.

[0027] The bottom side of the tank body 1 can be fixedly connected to the base 3, for example, by welding the tank body 1 to the base 3. Alternatively, the bottom side of the tank body 1 can be movably connected to the base 3, for example, by a threaded connection, to facilitate disassembly and maintenance.

[0028] A sealing component 6 is movably installed at the connection between the tank body 1 and the base 3. The sealing component 6 ensures that the hot water in the tank body 1 will not flow out from the contact point between the tank body 1 and the base 3 during the filtration process.

[0029] The sealing assembly 6 includes a first C-shaped retaining ring 601 and a second C-shaped retaining ring 602 movably installed on both sides of the contact point between the tank body 1 and the base 3. One end of the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 is hinged by a hinge 603. The outer surface of the other end of the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 is fixedly installed with a fixing protrusion 604. The two fixing protrusions 604 are connected by a fastening assembly. An airbag 606 is fixedly installed inside the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602, and the airbag 606 is annular.

[0030] When the worker places the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 onto the contact point between the tank 1 and the base 3, and gradually moves the two fixing protrusions 604 inward, this causes the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 to gradually move inward. This causes the inner side of the internal airbag 606 to gradually and tightly fit against the contact point between the tank 1 and the base 3. Simultaneously, the hinge 603 provides support for the rotation of the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602. Then, the two fixing protrusions 604 are fixedly connected together using fastening components, such as bolts and nuts. The bolts pass through the two fixing protrusions 604 sequentially and are secured by the nuts.

[0031] By moving the two fixed protrusions 604 closer together, the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 will move closer together, causing the internal airbag 606 to gradually and tightly fit against the contact point between the tank body 1 and the base 3, thereby increasing the sealing effect at the contact point between the tank body 1 and the base 3. Compared with traditional devices, this device uses the fixed protrusions 604 to move the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 closer together, causing the internal airbag 606 to expand and tightly fit against the contact point between the tank body 1 and the base 3, effectively enhancing the sealing and stability of the connection.

[0032] The fastening assembly includes a bidirectional threaded rod 605, with two fixing protrusions 604 internally threaded to the rod body of the bidirectional threaded rod 605 in different thread directions, and both ends of the bidirectional threaded rod 605 extending through the fixing protrusions 604.

[0033] The fastening assembly can also be a bidirectional threaded rod 605, with opposite thread directions on the two sections of the rod. Two fixing protrusions 604 are threaded onto the sections of the bidirectional threaded rod 605 with different thread directions. By rotating the bidirectional threaded rod 605, the two fixing protrusions 604 can be moved closer or further away. When rotating the bidirectional threaded rod 605 and moving the two fixing protrusions 604 closer, the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 can be moved closer simultaneously, thereby making the internal airbag 606 gradually fit tightly against the contact point between the tank 1 and the base 3. This device moves the two fixing protrusions 604 simultaneously by rotating the bidirectional threaded rod 605, making it simple and efficient to operate. After stopping the rotation of the bidirectional threaded rod 605, nuts can be threaded onto the sections of the bidirectional threaded rod 605 on the sides of the two fixing protrusions 604 that are further away from each other, to limit the two fixing protrusions 604 from moving further away.

[0034] In addition, a limiting block is provided between the two sections of the bidirectional threaded rod 605 with opposite thread directions to prevent the fixed protrusion 604 from moving to the rod body to which the other fixed protrusion 604 is screwed during the rotation of the bidirectional threaded rod 605.

[0035] The end of the bidirectional threaded rod 605 is provided with a rotating block, and the radius of the rotating block is larger than that of the bidirectional threaded rod 605.

[0036] By providing a rotating block at the end of the bidirectional threaded rod 605, with a radius larger than that of the bidirectional threaded rod 605, the rotating bidirectional threaded rod 605 can be effectively limited, preventing it from disengaging.

[0037] The filter cylinder 501 is wider at the top and narrower at the bottom, and the winding guide groove 502 is inclined inward.

[0038] The filter cylinder 501 has a shape that is wider at the top and narrower at the bottom, which can effectively increase the amount of water passing through the upper filter cylinder 501 and prevent water from being pulled by gravity to pass through the lower part of the winding guide groove 502 in large quantities. This makes the efficiency of the filter cylinder 501 more consistent. In addition, the winding guide groove 502 is inclined inward, which allows water to pass through the filter cylinder 501 quickly to filter and remove impurities.

[0039] If the tank 1 is of equal size at the top and bottom, the width of the winding guide groove 502 is wider at the top and narrower at the bottom, so that when the filter cylinder 501 is wider at the top and narrower at the bottom, the winding guide groove 502 can fit tightly against the inner wall of the tank 1.

[0040] Among them, the outer surface of the tank body 1 is fixedly fitted with a heat insulation sleeve 8.

[0041] The heat insulation sleeve 8 can effectively reduce heat loss when hot water passes through the tank 1.

[0042] The base 3 has a water outlet pipe 7 fixedly connected to its bottom side, which is connected to the water outlet 4 and is L-shaped.

[0043] By connecting the outlet pipe 7 to the outlet 4 in an L-shape, the filtered and impurity-removed hot water can flow into the heating equipment after being buffered by the L-shape of the outlet pipe 7, thus reducing the impact on the heating equipment.

[0044] The working principle and usage process of this application:

[0045] When the staff connects the external hot water supply pipe through the inlet 2, the hot water flows into the tank 1 through the inlet 2. Since the top of the filter cylinder 501 is sealed, the hot water flows in from both sides. And since the winding guide groove 502 is close to the inner wall of the tank 1, the hot water flows down along the spiral trajectory of the winding guide groove 502. At the same time, the water will gradually pass through the filter cylinder 501 for filtration and impurity removal along the winding guide groove 502. And through the opening of the guide slot 503, the water can flow directly into the winding guide groove 502 below, avoiding the water from concentrating in the winding guide groove 502 above and being filtered by the filter cylinder 501. This allows the filter cylinder 501 to be fully utilized for filtration.

[0046] When the worker attaches the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 to the contact point between the tank body 1 and the base 3, by rotating the bidirectional threaded rod 605, the two fixed protrusions 604 will gradually move inward, thereby causing the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602 to gradually move inward. Then, the internal airbag 606 will gradually fit tightly against the contact point between the tank body 1 and the base 3. At the same time, the hinge 603 provides support for the rotation of the first C-shaped retaining ring 601 and the second C-shaped retaining ring 602.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein.
