Description

Technical Field

[0001] This utility model belongs to the technical field of centralized heating system equipment and accessories, and relates to a filtration device for efficient heating. Background Technology

[0002] In the cold winter, urban heating is a key link in ensuring the comfort of residents' lives. Among them, the method of supplying heat by transporting hot water through pipes to the underfloor heating system inside the house is widely used. This heating mode relies on a huge and complex hot water transportation system. During the long-distance transportation of hot water, it is inevitable that various impurities such as mud, rust, and scale will be mixed in.

[0003] To prevent these impurities from entering users' homes and clogging the pre-buried water pipes, affecting the heating effect, or even damaging the heating system, it is particularly important to install filtration devices at key points in hot water transportation. Although some existing heating filtration devices can filter impurities in hot water to a certain extent, they have revealed obvious defects in actual use.

[0004] When the filter cartridge of the filter device becomes clogged due to long-term use and its filtration effect decreases, it needs to be replaced. However, due to system design and other reasons, some hot water delivery nodes cannot shut off the hot water supply before the filter cartridge replacement operation. This results in the continuous flow of hot water during the replacement process, which not only causes a lot of waste of hot water, but also makes the filter cartridge replacement operation difficult due to the impact of water flow, thus affecting the replacement efficiency.

[0005] Meanwhile, since hot water is being transported, the pipes maintain a high temperature throughout long-term operation. Without shutting off the hot water, the temperature of the pipes and filter devices themselves is even higher, which greatly inconveniences the operators during replacement work. Not only are they prone to scalding the operators, but the high temperature environment may also cause the replacement tools to deform due to heat, further increasing the difficulty and safety hazards of the replacement work. Utility Model Content

[0006] The technical problem this utility model aims to solve is that, due to system design and other reasons, some hot water delivery nodes cannot shut off the hot water supply before filter replacement. This results in continuous hot water flow during the replacement process, which not only wastes a lot of hot water but also makes filter replacement difficult due to water flow impact. Furthermore, without shutting off the hot water, the temperature of the pipes and the filter itself is even higher, which greatly inconveniences the operator. It not only easily burns the operator but may also cause the replacement tools to deform due to the high temperature environment, further increasing the difficulty and safety hazards of the replacement work.

[0007] The present invention discloses a heat-dissipating filtration device, comprising a housing, the housing being cylindrical in shape, a conversion cylinder rotatably connected inside the housing, and two rotating shafts fixedly connected to the two end faces of the conversion cylinder away from the center of the housing. The end of the rotating shaft away from the conversion cylinder passes through the housing and is movably connected to the housing. A driven grooved wheel is fixedly connected to the end of the rotating shaft away from the conversion cylinder. The end face of the conversion cylinder has evenly distributed water passage openings, and a filtration assembly is disposed within each water passage opening. Circular openings are provided near the top and bottom of the two end faces of the housing away from the conversion cylinder, corresponding to the water passage openings. Flange pipes are fixedly connected near the bottom of the two end faces of the housing away from the conversion cylinder, and the flange pipes communicate with the interior of the lower circular opening. A conversion transmission assembly is disposed on the outer wall of the housing, the conversion transmission assembly being used to drive the conversion cylinder to rotate as a whole.

[0008] Preferably, the filter assembly includes internal threads, a filter cylinder, external threads, a filter screen, loading / unloading protrusions, and loading / unloading grooves. Each of the several water inlets is equipped with a filter cylinder. External threads are formed on the outer wall of the filter cylinder away from the driven groove wheel. Internal threads are formed on the inner wall of the water inlet away from the driven groove wheel. The internal threads match the external threads. A filter screen is installed on the outer wall of the filter cylinder. Loading / unloading protrusions are symmetrically and fixedly connected to the end face of the filter cylinder away from the driven groove wheel. Loading / unloading grooves are symmetrically formed on the end face of the filter cylinder away from the driven groove wheel. Evenly distributed sealing gaskets are fixedly connected to the two end faces of the conversion cylinder away from the center of the housing. The sealing gaskets match the water inlets.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] like Figures 1 to 8 As shown, the device includes a housing 1, which is cylindrical in shape. A conversion cylinder 2 is rotatably connected inside the housing 1. A rotating shaft 14 is fixedly connected to each of the two end faces of the conversion cylinder 2 away from the center of the housing 1. The end of the rotating shaft 14 away from the conversion cylinder 2 passes through the housing 1 and is movably connected to the housing 1. A driven grooved wheel 18 is fixedly connected to the end of the rotating shaft 14 away from the conversion cylinder 2. Water passage openings 3 are evenly distributed on the end face of the conversion cylinder 2. A filter assembly is installed in the water passage opening 3. Circular openings 11 are opened near the top and bottom of the two end faces of the housing 1 away from the conversion cylinder 2. The circular openings 11 correspond to the water passage openings 3. Flange pipes 15 are fixedly connected to the bottom of the two end faces of the housing 1 away from the conversion cylinder 2. The flange pipes 15 are connected to the interior of the circular openings 11 on the lower side. A conversion transmission assembly is provided on the outer wall of the housing 1. The conversion transmission assembly is used to drive the conversion cylinder 2 to rotate as a whole.

[0027] like Figures 2-8 As shown, the filter assembly includes an internal thread 4, a filter cylinder 5, an external thread 6, a filter screen 7, a loading / unloading protrusion 8, and a loading / unloading groove 9. A filter cylinder 5 is installed in each of several water inlets 3. An external thread 6 is provided on the outer wall of the filter cylinder 5 away from the driven groove wheel 18. An internal thread 4 is provided on the inner wall of the water inlet 3 away from the driven groove wheel 18. The internal thread 4 matches the external thread 6. A filter screen 7 is installed on the outer wall of the filter cylinder 5. A loading / unloading protrusion 8 is symmetrically and fixedly connected to the end face of the filter cylinder 5 away from the driven groove wheel 18. A loading / unloading groove 9 is symmetrically provided on the end face of the filter cylinder 5 away from the driven groove wheel 18. Two evenly distributed sealing gaskets 13 are fixedly connected to the two end faces of the conversion cylinder 2 away from the center of the housing 1. The sealing gaskets 13 match the water inlets 3. The end of the sealing gasket 13 away from the conversion cylinder 2 abuts against the inner wall of the housing 1. Several evenly distributed drainage grooves 10 are provided on the inner wall of the water inlet 3.

[0028] The filter cartridge 5 in this technical solution is made of stainless steel and is installed in the water inlet 3 by means of threaded connection. The mounting and dismounting protrusion 8 and mounting and dismounting groove 9 are for easy tool clamping and leverage, so as to facilitate the disassembly and installation of the filter cartridge 5. During use, the sealing gasket 13 is in tight contact with the inner wall of the housing 1, so that hot water will not leak when passing through the filter cartridge 5 and the water inlet 3.

[0029] like Figures 1 to 8 As shown, the conversion transmission assembly includes a transmission pulley 22, a transmission belt 20, and a servo motor 19. The servo motor 19 is mounted on the outside of the housing 1. The output end of the servo motor 19 is fixedly connected to the transmission pulley 22. The transmission belt 20 is installed between the transmission pulley 22 and the driven pulley 18.

[0030] The servo motor 19 in this technical solution has position control, speed control, torque control, and electric self-locking function. Before use, programming instructions need to be input to make the servo motor 19 drive the conversion cylinder 2 to rotate only 90 degrees each time and then stop, and perform electric self-locking after stopping. In this way, the conversion cylinder 2 will not rotate during use. Moreover, the tight contact of the sealing gasket 13 can increase the friction between the conversion cylinder 2 and the housing 1, thereby preventing the conversion cylinder 2 from rotating during operation.

[0031] Each of the two flanges 15 is equipped with a pressure valve 16 and several bolts 17. The pressure valves 16 can clearly indicate whether the filter cartridge 5 is clogged. Therefore, if the filter cartridge 5 is clogged without shutting off the terminal water source, the water pressure of the pressure valve 16 on the water inlet side will increase, and the water pressure of the pressure valve 16 on the other side will decrease. The degree of clogging of the filter cartridge 5 can also be determined by observing the pressure valve 16 on the water inlet side, further increasing the convenience of use.

[0032] In addition, the end of the conversion cylinder 2 away from the center of the housing 1 is symmetrically provided with sealing grooves 21, and the inner wall of the housing 1 is symmetrically fixed with sealing rings 12 that match the sealing grooves 21. The sealing rings 12 can further increase the sealing between the housing 1 and the conversion cylinder 2, and at the same time increase the friction between the housing 1 and the conversion cylinder 2, so that the conversion cylinder 2 will not rotate during operation.

[0033] Working Principle: In this technical solution, the housing 1 needs to be installed as a whole on a node in the water supply system. Before installation, multiple water inlets 3 need to be machined to install filter cartridges 5, and one of the filter cartridges 5 should be aligned with the flange pipe 15. Next, the housing 1 is installed and fixed on the delivery pipe node using bolts 17 on the flange pipe 15. During use, the pressure index of the pressure valve 16 can be observed to determine if the filter cartridge 5 is clogged. If the filter cartridge 5 is clogged, the pressure of the pressure valve 16 on the input water source side will increase due to the blockage, while the pressure of the pressure valve 16 on the output water source side will decrease. If this occurs, the servo motor 19 can be started by an external control power supply to drive the transmission pulley 22. The transmission pulley 22, through the transmission belt 20, drives the driven pulley 18 and the rotating shaft 14 to rotate. Simultaneously, the rotating shaft 14 drives the conversion cylinder 2 to rotate. This allows the filter cartridge 5 that needs replacement to be rotated to the upper side, and the new filter cartridge 5 to align with the lower circular opening 11. This allows for filter cartridge 5 replacement without interrupting water supply at the terminal.

[0034] Next, the filter cartridge 5, which has been moved to the upper side, can be rotated using a tool that matches the loading / unloading protrusion 8 and loading / unloading groove 9. This allows the filter cartridge 5 to rotate and disengage from the water inlet 3, and be removed from the upper circular opening 11. Then, the filter cartridge 5 can be replaced or cleaned. After cleaning, it can be rotated and installed back into the water inlet 3. In this way, the cleaned filter cartridge 5 can be used as a spare filter element. The above operation can effectively solve the problem that some hot water delivery nodes cannot shut down the hot water delivery before filter element replacement due to system design and other reasons. This results in continuous hot water flow during the replacement process, which not only wastes a lot of hot water, but also makes filter element replacement difficult due to water flow impact. At the same time, without shutting down the hot water, the temperature of the pipes and the filter device itself is even higher, which brings great inconvenience to the operator. It is not only easy to burn the operator, but also the replacement tools may be deformed due to heat in the high temperature environment, further increasing the difficulty of the replacement work and the safety hazards.

[0035] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
