Description

Technical Field

[0001] This utility model relates to the field of carbon emission monitoring technology, and more specifically, to a self-cleaning carbon emission monitoring device for the production of environmentally friendly building materials. Background Technology

[0002] During the production of environmentally friendly building materials (such as aerated concrete blocks, lightweight partition boards, and sintered bricks), equipment such as kilns, dryers, and mills emit flue gas containing carbon dioxide and particulate matter. To implement carbon emission control, real-time online monitoring of these flue gas emissions is necessary.

[0003] For example, the specification of the "Carbon Emission Monitoring Device with Automatic Alarm" disclosed in Chinese Utility Model Patent (Publication No.: CN219977939U) states that: by setting up a filtration mechanism, when the device collects gas, the gas passes through the filtration mechanism before entering the monitoring instrument. After the gas enters the filter cylinder in the filtration mechanism through the second gas tube, since the end of the second gas tube extends into the interior of the filter liquid in the filter cylinder, the gas is directly discharged into the filter liquid, and then moves upward and is gradually discharged. During this process, the solid particles in the gas are captured by the filter liquid and cannot be separated, so that the gas after passing through the filtration mechanism will no longer contain solid particles, ensuring the accuracy of the final detection. Regarding the aforementioned technologies, this device has some shortcomings. In actual use, the filtrate, as a consumable medium, requires frequent shutdowns for replacement, which not only generates a large amount of waste liquid, increases operation and maintenance costs and environmental burden, but also makes the filtrate prone to saturation and failure after long-term use. At the same time, flue gas passing through the filtrate will carry a large number of tiny droplets into the subsequent gas path. These droplets adhere to the optical window or sensor surface of the carbon emission monitor, which will interfere with optical path transmission or cause signal drift, thereby significantly reducing the detection accuracy and long-term stability of carbon dioxide concentration.

[0004] Therefore, we have made improvements to this by proposing a self-cleaning carbon emission monitoring device for the production of environmentally friendly building materials. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a self-cleaning carbon emission monitoring device for the production of environmentally friendly building materials, which solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A self-cleaning carbon emission monitoring device for environmentally friendly building materials production includes a housing. Symmetrically distributed partitions are fixedly installed inside the housing. A partition frame is fixedly installed between two partitions. The housing is divided into a lower chamber and an upper chamber by the partition frame between the two partitions. A filter port is provided on the partition frame. The lower chamber and upper chamber are connected through the filter port. A filter screen is fixedly installed inside the filter port. An air blowing assembly is provided at the top of the housing, and a sealing assembly is provided at the bottom of the housing. An air inlet assembly is provided at one end of the housing, and an air outlet assembly is provided at the other end of the housing. The air blowing assembly includes an air pump fixedly installed on the top of the housing. An output pipe is fixedly installed at the output end of the air pump. A second valve is provided on the output pipe. One end of the output pipe passes through the housing and extends to the upper part of the upper chamber.

[0007] As a preferred technical solution of this application, the sealing assembly includes a discharge port opened at the bottom of the box body, the discharge port being connected to the interior of the lower chamber, a sliding groove being opened on the inner wall of the discharge port, the sliding groove being connected to the lower side of the front of the box body, a sealing plate being slidably inserted into the sliding groove, and a first electric telescopic rod being fixedly installed on the bottom of the box body on one side of the discharge port, the driving end of the first electric telescopic rod being fixedly connected to one side of the front end of the sealing plate.

[0008] As a preferred technical solution of this application, the air intake assembly includes an air intake pipe disposed at one end of the housing, one end of the air intake pipe passing through a partition and communicating with the interior of the lower chamber, and a first valve is disposed on the air intake pipe.

[0009] As a preferred technical solution of this application, the air outlet assembly includes an air outlet pipe disposed at the other end of the housing, one end of the air outlet pipe passing through another partition and communicating with the interior of the upper chamber, and a carbon emission monitor and an air pump are respectively disposed on the air outlet pipe.

[0010] As a preferred technical solution of this application, a connecting pipe is fixedly connected to one end of the output pipe located inside the upper chamber, and a sealing cover is fixedly connected to the bottom end of the connecting pipe. The sealing cover is adapted to the position of the filter port. A second electric telescopic rod is fixedly installed on one side of the top of the box. The driving end of the second electric telescopic rod passes through the box and extends into the interior of the upper chamber. The driving end of the second electric telescopic rod is fixedly connected to the sealing cover.

[0011] As a preferred technical solution of this application, the connecting pipe is made of an elastic telescopic flexible hose.

[0012] As a preferred technical solution of this application, a sealing gasket is provided on the inner wall of the slide.

[0013] As a preferred technical solution of this application, a controller is fixedly installed on one side of the front of the box, and a support frame is fixedly installed on the bottom of the box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1.

This solves the problems of frequent liquid filtration replacement, waste liquid generation, high maintenance costs, and easy saturation failure. At the same time, it avoids the defect of sensor accuracy degradation caused by liquid droplets being carried by flue gas after passing through the liquid. By scraping away accumulated dust by sliding the sealing plate along the chute and cooperating with high-pressure gas backflushing, an online self-cleaning function without manual disassembly is achieved, which greatly improves monitoring accuracy and operational stability.

[0015] 2. Through the coordinated use of the connecting pipe, sealing cover, and second electric telescopic rod, during backflushing cleaning, the second electric telescopic rod drives the sealing cover to move downwards until it seals against the filter port, ensuring that all high-pressure gas blows downwards and backflushes the filter screen, avoiding the problem of incomplete cleaning due to airflow leakage; the connecting pipe adopts an elastic telescopic hose, which can adapt to the lifting and lowering movement of the sealing cover to ensure that the air path is always unobstructed; it achieves precise and efficient backflushing cleaning of the filter screen, significantly improves the self-cleaning effect, extends the service life of the filter screen, and further reduces the frequency of manual maintenance.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] 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.

[0021] 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.

[0022] Example 1 Please refer to Figures 1-5 A self-cleaning carbon emission monitoring device for environmentally friendly building materials production includes a housing 1. Symmetrically distributed partitions 10 are fixedly installed inside the housing 1. A partition frame 11 is fixedly installed between the two partitions 10. The housing 1 is divided into a lower chamber 12 and an upper chamber 13 by the partition frame 11 between the two partitions 10. A filter port 14 is provided on the partition frame 11. The lower chamber 12 and the upper chamber 13 are connected through the filter port 14. A filter screen is fixedly installed inside the filter port 14. An air blowing assembly 7 is provided on the top of the housing 1. A sealing assembly 6 is provided on the bottom of the housing 1. An air inlet assembly is provided at one end of the housing 1, and an air outlet assembly is provided at the other end of the housing 1. The air blowing assembly 7 includes an air blowing pump 20 fixedly installed on the top of the housing 1. An output pipe 21 is fixedly installed at the output end of the air blowing pump 20. A second valve 25 is provided on the output pipe 21. One end of the output pipe 21 passes through the housing 1 and extends to the upper part of the upper chamber 13.

[0023] Furthermore, the sealing assembly 6 includes a discharge port 16 located at the bottom of the housing 1, which is connected to the interior of the lower chamber 12. A groove 17 is formed on the inner wall of the discharge port 16, which is connected to the lower front side of the housing 1. A sealing plate 18 is slidably inserted into the groove 17. A first electric telescopic rod 19 is fixedly installed on one side of the discharge port 16 at the bottom of the housing 1, and the drive end of the first electric telescopic rod 19 is fixedly connected to one side of the front end of the sealing plate 18. The sealing plate 18 is slidably inserted into the groove 17 on the inner wall of the discharge port 16 and is driven to open and close by the first electric telescopic rod 19. During normal monitoring, the sealing plate 18 closes the discharge port 16 to ensure airtightness; during cleaning, it automatically opens. During the sliding process, solid particles accumulated on the surface of the sealing plate 18 are scraped off and discharged by the edge of the inner wall of the discharge port 16, achieving automatic cleaning and discharge of accumulated dust and avoiding the tedious operation of manual disassembly and cleaning.

[0024] Furthermore, the air intake assembly includes an air intake pipe 3 disposed at one end of the housing 1. One end of the air intake pipe 3 passes through a partition 10 and is connected to the interior of the lower chamber 12, ensuring that the flue gas to be tested is directly introduced into the lower chamber 12. A first valve 4 is provided on the air intake pipe 3. The first valve 4 is used to close the air intake during backflushing cleaning, block the air path, and prevent the backflushing airflow from escaping from the air intake pipe 3.

[0025] Furthermore, the exhaust assembly includes an exhaust pipe 8 located at the other end of the housing 1. One end of the exhaust pipe 8 passes through another partition 10 and is connected to the interior of the upper chamber 13, ensuring that the flue gas purified by the filter can smoothly enter the exhaust pipe 8. A carbon emission monitor 9 and a vacuum pump 15 are respectively installed on the exhaust pipe 8. The vacuum pump 15 provides stable power for the flow of flue gas, while the carbon emission monitor 9 performs real-time detection of the filtered gas.

[0026] Furthermore, a sealing gasket is provided on the inner wall of the slide 17. This effectively prevents dust or fumes in the lower chamber 12 from leaking outwards along the gap between the sealing plate 18 and the slide 17, ensuring the airtightness and cleanliness of the device during operation.

[0027] Furthermore, a controller 5 is fixedly installed on one side of the front of the housing 1, and a support frame 2 is fixedly installed on the bottom of the housing 1.

[0028] Example 2 The self-cleaning carbon emission monitoring device for environmentally friendly building material production provided in Example 1 is further optimized. Specifically, one end of the output pipe 21 located inside the upper chamber 13 is fixedly connected to a connecting pipe 22, and the bottom end of the connecting pipe 22 is fixedly connected to a sealing cover 23. The sealing cover 23 is adapted to the position of the filter port 14. A second electric telescopic rod 24 is fixedly installed on one side of the top of the box 1. The driving end of the second electric telescopic rod 24 passes through the box 1 and extends into the interior of the upper chamber 13. The driving end of the second electric telescopic rod 24 is fixedly connected to the sealing cover 23.

[0029] Furthermore, the connecting pipe 22 is made of a flexible, telescopic hose. This allows it to adapt to the expansion and contraction of the sealing cover 23 during its lifting and lowering process, ensuring that the air passage remains unobstructed at all times.

[0030] It should be noted that the controller control circuit can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0031] The usage process of the self-cleaning carbon emission monitoring device for environmentally friendly building materials production provided by this utility model is as follows: After the device is started, the suction pump 15 operates, allowing the flue gas to be tested to enter the lower chamber 12 inside the housing 1 through the inlet pipe 3. Since the lower chamber 12 and the upper chamber 13 are connected by the filter port 14 on the partition frame 11 and a filter screen is fixedly installed inside the filter port 14, the flue gas must pass through the filter screen to enter the upper chamber 13. During this process, solid particles in the flue gas are intercepted by the filter screen and accumulate on the upper surface of the sealing plate 18 at the bottom of the lower chamber 12. Subsequently, the filtered clean flue gas enters the carbon emission monitor 9 through the outlet pipe 8 for carbon dioxide concentration detection. When the dust accumulated on the surface of the filter screen after long-term use causes airflow obstruction, the controller 5 first controls the second valve 25 to open and the first valve 4 to close, thereby blocking the air intake and introducing a backflushing air source. Then, the second electric telescopic rod 24 in the air blowing assembly 7 drives the sealing cover 23 to move downwards until it seals against the filter port 14. At the same time, the first electric telescopic rod 19 drives the sealing plate 18 to slide along the slide groove 17 to open the discharge port 16. During the process of the sealing plate 18 sliding outwards, the solid particles accumulated on the upper surface of the sealing plate 18 are scraped off by the inner wall edge of the discharge port 16 and discharged outside the box 1 through the discharge port 16. At this time, the air blowing pump 20 works, and the high-pressure gas blows the filter screen downwards from the sealing cover 23 through the output pipe 21 and the connecting pipe 22, blowing the dust attached to the filter screen backwards. The dust blown off is also discharged through the discharge port 16 under the action of gravity and airflow, thereby realizing the online self-cleaning function without manual disassembly.
