Description

Technical Field

[0001] This invention relates to the field of smart heating technology, and in particular to a safety protection device for urban smart heating pipeline networks. Background Technology

[0002] In heating systems, the cleanliness of circulating water directly affects the system's operating efficiency, equipment lifespan, and heating quality. After long-term use, heating pipes will corrode internally, producing a large amount of impurities and rust. During construction and operation, the pipe network will inevitably be mixed with solid particles such as mud and suspended matter, which can easily accumulate and clog user pipes, causing increased system resistance, decreased heat exchange efficiency, and increased heat consumption. In severe cases, it can even lead to users not receiving the required heating temperature. In addition, the accumulation of impurities will accelerate the wear and damage of heating equipment and shorten its service life.

[0003] Currently, the filtration equipment commonly used in heating systems mainly includes traditional Y-type filters, perforated plate filters, and some simple backwash filters.

[0004] Traditional filter screens are limited by their structure and can usually only intercept larger particles of impurities. They cannot effectively remove fine particles, rust particles and suspended solids carried in heating circulating water. Y-type filters do not have a cleaning function and are prone to clogging after long-term use, requiring timely shutdown and cleaning. Although some existing filtration equipment has a backwashing function, the backwashing effect is often unsatisfactory in actual use.

[0005] On the one hand, insufficient backwash water pressure and flow rate make it difficult to remove firmly attached impurities from the surface and inside of the filter screen; on the other hand, the filter screen is usually fixed in position. After the filter screen filters out a large number of impurities, the impurities accumulate on the inner wall of the pipe where the filter screen is located, making it easy for impurities to adhere to the inner wall of the pipe as well. Although backwashing can perform preliminary cleaning of the filter screen, it cannot effectively clean the pipe where the filter screen is located during the backwashing process, which will still affect the water quality.

[0006] Therefore, a safety protection device for urban smart heating pipeline networks is proposed. Summary of the Invention

[0007] Therefore, the technical problem to be solved by the present invention is that although partial backwashing can perform preliminary cleaning of the filter screen, it cannot effectively clean the pipe at the location where the filter screen is located during the backwashing process.

[0008] The above-mentioned technical problems are solved by the following technical solution: This invention proposes a safety protection device for urban smart heating pipeline networks, comprising, The conveying channel includes an annular channel, and an inlet channel, an outlet channel, and a cleaning channel disposed on the annular channel; A filtration mechanism is disposed within the annular channel; A drive mechanism, which is located on the annular channel, is used to control the filter mechanism to rotate inside the annular channel and scrape the inner wall of the annular channel; The cleaning channel is equipped with a drain valve.

[0009] In a preferred embodiment of the smart urban heating network safety protection device of the present invention: the discharge channel and the cleaning channel are respectively located on opposite sides of the annular channel.

[0010] In a preferred embodiment of the smart urban heating network safety protection device of the present invention: the filtration mechanism includes an annular track slidably disposed in the annular channel, and a sliding ring body disposed on the annular track, wherein a filter bucket is disposed on the sliding ring body.

[0011] In a preferred embodiment of the smart urban heating network safety protection device of the present invention: the filter barrel is arranged facing the first direction.

[0012] In a preferred embodiment of the smart urban heating network safety protection device of the present invention: the filter barrel is arranged facing the second direction.

[0013] In a preferred embodiment of the smart urban heating network safety protection device of the present invention: at least three filter barrels are provided and are distributed in a circular pattern outside the annular track.

[0014] In a preferred embodiment of the urban smart heating network safety protection device of the present invention: the inner wall of the annular track is provided with toothed blocks; The driving mechanism includes a drive motor disposed on the annular channel and a gear disposed on the output shaft of the drive motor; The gear is used to mesh with the tooth block.

[0015] In a preferred embodiment of the smart urban heating network safety protection device of the present invention: it further includes a first gate valve disposed on the annular channel; The valve plate of the first slide gate valve is the first plate body; The first plate is positioned between the entry channel and the cleanup channel.

[0016] In a preferred embodiment of the urban smart heating network safety protection device of the present invention: it further includes a second gate valve disposed on the annular channel; The valve plate of the second slide gate valve is a second plate body, and an inner baffle is provided on the second plate body; The inner baffle is located between the discharge channel and the cleaning channel.

[0017] In a preferred embodiment of the urban smart heating network safety protection device of the present invention: it further includes a third gate valve disposed on the annular channel; The valve plate of the third slide valve is a third plate body, and the third plate body is provided with a through hole; The third plate is located between the discharge channel and the cleaning channel.

[0018] The beneficial effects of this invention are as follows: Circulating water enters the annular channel from the inlet channel and is finally discharged from the outlet channel. The circulating water is filtered by the filtration mechanism, and impurities are intercepted by the filtration mechanism. When impurity cleaning is required, the drain valve is opened. Due to the pressure difference between the inside and outside of the equipment in the heating system, the pressure inside the conveying channel is high, so the circulating water will be discharged from the drain valve. During the discharge process, the impurities intercepted by the filter are sprayed out from the cleaning channel, realizing the flushing operation. At the same time, the filtration mechanism can be controlled to rotate in the annular channel by the drive mechanism, which helps to push the impurities inside to the cleaning channel to realize the discharge. Furthermore, the movement of the filtration mechanism scrapes and cleans the inner wall of the annular channel. By pushing the impurities closer to the cleaning channel and scraping the inner wall of the annular channel where the impurities are stored, the cleaning effect can be improved, thereby improving the water quality of the circulating water.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0030] Reference Figures 1-7 This embodiment provides a safety protection device for a smart urban heating network, including a conveying channel 1, which includes an annular channel 11, and an inlet channel 12, an outlet channel 13, and a cleaning channel 14 disposed on the annular channel 11; Specifically, the bottom outer wall of the annular channel 11 is provided with an inlet channel 12 for the circulation water to enter. The outlet channel 13 and the cleaning channel 14 are symmetrically arranged on both sides of the outer wall of the annular channel 11. The area above the connection between the annular channel 11 and the outlet channel 13 and the cleaning channel 14 forms a buffer space that can buffer suspended impurities.

[0031] The filter mechanism 2 is located inside the annular channel 11; the filter mechanism 2 is used to filter the circulating water flowing inside the channel 1.

[0032] The drive mechanism 3, which is located on the annular channel 11, is used to control the filter mechanism 2 to rotate inside the annular channel 11 and scrape the inner wall of the annular channel 11. By controlling the movement of the filter mechanism 2 through the drive mechanism 3, not only can the inner wall of the annular channel 11 be cleaned, but the position of the filter mechanism 2 can also be changed.

[0033] The cleaning channel 14 is equipped with a drain valve 4, which facilitates the cleaning of the filter mechanism 2.

[0034] Reference Figures 1-7 During use, the drain valve 4 is closed. Circulating water enters the annular channel 11 from the inlet channel 12 and is finally discharged from the outlet channel 13. The circulating water is filtered by the filter mechanism 2, and impurities are intercepted by the filter mechanism 2. When impurity cleaning is required, the drain valve 4 is opened. Due to the pressure difference inside and outside the equipment in the heating system, the pressure inside the conveying channel 1 is high, so the circulating water will be discharged from the drain valve 4. During the discharge process, the impurities intercepted by the filter are sprayed out from the cleaning channel 14 to achieve the flushing operation. At the same time, the filter mechanism 2 can be controlled to rotate in the annular channel 11 by the drive mechanism 3, which helps to push the impurities inside to the cleaning channel 14 to achieve sewage discharge. The movement of the filter mechanism 2 scrapes and cleans the inner wall of the annular channel 11. By pushing the impurities closer to the cleaning channel 14 and scraping the inner wall of the annular channel 11 where the impurities are stored, the cleaning effect can be improved, thereby improving the water quality of the circulating water.

[0035] For example, refer to Figures 1-3 The discharge channel 13 and the cleaning channel 14 are respectively located on opposite sides of the annular channel 11. By keeping the discharge channel 13 and the cleaning channel 14 far apart, the tendency of impurities to flow towards the discharge channel 13 can be reduced when cleaning impurities. Since the speed of the circulating water sprayed out of the cleaning channel 14 is greater than the flow speed of the circulating water in the discharge channel 13 after the drain valve 4 is opened, the pressure is low where the flow velocity is high, and impurities will be more inclined to move towards the cleaning channel 14.

[0036] Reference Figures 1-7 In one optional embodiment, the filtration mechanism 2 includes an annular track 21 slidably disposed within the annular channel 11, and a sliding ring 22 disposed on the annular track 21, with a filter barrel 23 disposed on the sliding ring 22.

[0037] The filter buckets 23 are provided in at least three and are distributed in a circular pattern outside the annular track 21. The annular track 21 is slidably disposed inside the annular channel 11. The outer wall of the sliding ring 22 matches the cross-sectional dimensions of the annular channel 11. The sliding ring 22 can slide along the inner wall of the annular channel 11. The sliding ring 22 is preferably made of rubber, which can provide a certain degree of sealing while also using the friction of the rubber to clean the inner wall of the annular channel 11.

[0038] The inner wall of the annular track 21 is provided with toothed blocks 211; a number of toothed blocks 211 are provided and are evenly distributed on the inner wall of the annular track 21.

[0039] The drive mechanism 3 includes a drive motor 31 mounted on the annular channel 11 and a gear 32 mounted on the output shaft of the drive motor 31; the gear 32 is used to mesh with the gear block 211.

[0040] In use, the operation of the drive motor 31 causes the gear 32 to rotate, which in turn pushes the tooth block 211, causing the annular track 21 to rotate inside the annular channel 11, thereby displacing the filter barrel 23.

[0041] It should be noted that due to the annular arrangement of the annular channel 11, the relative filtration diameter of the filter barrel 23 is increased, and the filtration area of ​​the filter barrel 23 is increased, which can increase the efficiency of operation. After the circulating water enters the interior of the annular channel 11 through the inlet channel 12, the flow rate of the circulating water will be reduced and it will flow in two paths, eventually converging again at the outlet channel 13. That is, at least two filter barrels 23 can be filtered simultaneously, and the filtration area is significantly increased. In addition, the flow rate of the circulating water is reduced during filtration, which can increase the filtration effect and reduce the situation of impurities clogging the filter holes.

[0042] Reference Figure 4 In one optional embodiment, the filter barrel 23 is oriented toward a first direction, and the direction from the barrel opening to the barrel body of the filter barrel 23 is clockwise.

[0043] like Figure 4 In the embodiment shown, after the circulating water enters the annular channel 11, it flows simultaneously to both sides of the annular channel 11. After being filtered by the filter bucket 23, it finally converges at the discharge channel 13 and is discharged from the discharge channel 13.

[0044] When cleaning impurities, refer to Figure 4 First, open the drain valve 4, and then control the filter bucket 23 to rotate in the first direction, that is, rotate clockwise, using the sliding ring 22 to clean the impurities and the impurities on the inner wall of the annular channel 11.

[0045] Reference Figure 7 For example, the filter barrel 23 is oriented in the second direction, and the direction from the opening of the filter barrel 23 to the barrel body is counterclockwise. When cleaning impurities, refer to... Figure 7 First, open the drain valve 4, then control the filter bucket 23 to rotate clockwise through the drive mechanism 3, and use the sliding ring 22 to clean the impurities and the impurities on the inner wall of the annular channel 11.

[0046] Reference Figures 1-7 In one optional embodiment, it further includes a first slide gate valve 5 disposed on the annular channel 11; the valve plate of the first slide gate valve 5 is a first plate body 51; the first plate body 51 is in a planar state.

[0047] The first plate 51 is positioned between the entry channel 12 and the cleanup channel 14.

[0048] During normal use, the first plate 51 can be pulled out, at which time multiple filter canisters 23 can be used simultaneously.

[0049] It should be noted that multiple pressure sensors can be installed inside the annular channel 11 to detect the internal pressure. The clogging status of the internal filter canister 23 can be determined by pressure analysis. When the pressure difference is too large, it is determined that the filter canister 23 is severely clogged and needs to be cleaned.

[0050] Move the filter bucket 23 that needs to be cleaned to the top of the annular channel 11, and then close the first plate 51. In this way, during the backwashing process, the circulating water flows through the top of the annular channel 11, which can increase the pressure during the backwashing and improve the backwashing effect.

[0051] Reference Figures 1-7 It also includes a second slide valve 6 disposed on the annular channel 11; The valve plate of the second slide valve 6 is the second plate body 61, and the second plate body 61 is provided with an inner baffle 62. The size of the inner baffle 62 matches the end size of the filter barrel 23. When it is necessary to increase the pressure during backwashing, the inner baffle 62 can be used to block the end of the filter barrel 23, so that the circulating water enters from the side of the filter barrel 23, thereby improving the cleaning effect on the side of the filter barrel 23.

[0052] The inner baffle 62 is located between the discharge channel 13 and the cleaning channel 14.

[0053] Reference Figures 1-7 It also includes a third slide valve 7 located on the annular channel 11; The valve plate of the third slide valve 7 is the third plate body 71, and the third plate body 71 is provided with a through hole 72. The third plate 71 is located between the discharge channel 13 and the cleaning channel 14.

[0054] The size of the through hole 72 is slightly larger than the size of the outer wall of the filter barrel 23. When it is necessary to enhance the cleaning effect on the end of the filter barrel 23, the third plate 71 can be extended so that the through hole 72 is aligned with the end of the filter barrel 23. At this time, circulating water will enter from the end of the filter barrel 23 to enhance the backwashing effect and strengthen the cleaning effect on the end of the filter barrel 23.

[0055] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
