Anti-clogging heater damper

Abstract

This utility model relates to the field of flame arrester technology and discloses an anti-clogging flame arrester for a heating furnace. In pipeline transportation systems, the medium usually carries impurities such as dust and particulate matter. If these impurities are not pretreated, when they accumulate to a certain extent, they will not only significantly increase the pressure loss of the flame arrester and reduce the medium flow efficiency, but may also damage the structural integrity of the flame arresting element, leading to the failure of the flame arresting performance. This utility model sets up an anti-clogging component. The medium in the pipeline enters the sleeve, and the gas medium drives the filter frame to move towards the flame arresting core. The impurities in the gas medium are filtered by filter screens A, B, and C, thereby reducing the risk of flame arresting core clogging. When the pipeline stops transporting gas, the filter frame is reset under the action of the spring, and the filter screens A and B are cleared by the unblocking cone to ensure that the subsequent gas medium continues to be filtered.

Description

Technical Field

[0001] This utility model relates to the field of flame arrester technology, and in particular to a flame arrester for a heating furnace that prevents clogging. Background Technology

[0002] A flame arrester is a safety device used to prevent the spread of flames from flammable gases and liquid vapors. It is generally installed in pipelines that transport flammable gases or on ventilated tanks to prevent the spread of flames, deflagration, or detonation. It consists of a flame arrestor core, a flame arrestor shell, and accessories.

[0003] In Chinese patent application number 202320225071.6, this utility model discloses a pipeline flame arrester, including a housing one and a housing two. The housing one and housing two have the same structure. Both housing one and housing two have a flame-arresting layer installed inside. Both housing one and housing two are fixedly connected to a limit ring. Both housing one and housing two have several adjustment holes on one side of the limit ring. The adjustment holes are provided with limit blocks. A positioning bolt passes through the limit block. One end of the positioning bolt is screwed into the adjustment hole. Both housing one and housing two have a rotating connecting plate between the limit block and the limit ring. This device allows the rotatable housing one and housing two by changing the distance between the connecting plates, making it easier for the operator to disassemble the entire device.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: In pipeline transportation systems, the medium usually carries impurities such as dust and particulate matter. If no pretreatment measures are taken for these impurities, when the impurities accumulate to a certain extent, they will not only significantly increase the pressure loss of the flame arrester and reduce the medium flow efficiency, but may also damage the structural integrity of the flame arresting element, leading to the failure of the flame arresting performance, and thus posing a serious threat to the safe and stable operation of the entire pipeline transportation device. Utility Model Content

[0005] The technical problem to be solved by this utility model is that in the existing technology, the medium transported in the pipeline contains impurities during the use of the flame arrester. These impurities will block the flame arrester and ultimately affect its normal use. Therefore, we propose a flame arrester for heating furnace that prevents blockage.

[0006] To achieve the above objectives, this application adopts the following technical solution: a flame arrestor for an anti-clogging heating furnace, comprising: a flame arresting component, an anti-clogging component installed inside the flame arresting component, the flame arresting component including a sleeve, a connector installed on the sleeve, two sets of mating sleeves fixedly connected to the outer surface of the sleeve, bolts installed on the mating sleeves, a nut A threadedly connected to one end of the bolts, the two sets of mating sleeves being installed together by the bolts and the nut A, a flame arresting core being provided inside the sleeve, the anti-clogging component including a mounting frame, the mounting frame being fixedly installed on the inner wall of the sleeve, a filter screen A being installed on the mounting frame, a filter frame being provided on one side of the filter screen A, a filter screen B being installed on the filter frame, a clearing cone being installed on both the filter screen A and the filter screen B, a connecting rod being fixedly connected to one side of the filter frame, one end of the connecting rod movably extending through the mounting frame to one side, a nut B threadedly connected to one end of the connecting rod, a spring being fixedly connected to one side of the nut B, and a collection cover being fixedly connected to the other side of the filter frame.

[0007] Preferably, the connector is shaped like a frustum, and a flange is fixedly connected to one end of the connector. The flange has several mounting holes.

[0008] This allows for easy installation of the entire flame arrester onto the corresponding pipe via a flange.

[0009] Preferably, the diameter of the mounting frame is larger than the diameter of the filter frame, and the filter frame does not directly contact the inner surface of the sleeve;

[0010] This is to prevent the filter frame from scratching the inner surface of the sleeve during movement.

[0011] Preferably, both filter screen A and filter screen B act on the flame arrestor core. The mesh diameter of filter screen A is larger than that of filter screen B. Filter screen A is closer to the input end of the flame arrestor, and filter screen B is placed between filter screen A and the flame arrestor core.

[0012] It is used to filter the medium entering the sleeve, preventing impurities carried in the medium from directly contacting the flame arrestor core, thereby blocking the flame arrestor core and affecting the normal operation of the entire device.

[0013] Preferably, filter screen A and filter screen B are arranged alternately, with the unclogging cone installed on filter screen A corresponding to the filter hole on filter screen B, and the unclogging cone installed on filter screen B corresponding to the filter hole on filter screen A.

[0014] This is used to make two sets of cleaning cones work together to clean filter screens A and B, preventing impurities from clogging them.

[0015] Preferably, the collection cover is semi-circular, with through holes, and a filter screen C is installed inside the collection cover;

[0016] This is used to allow the medium passing through filter screen B to undergo a second filtration process, further ensuring the cleanliness of the medium in contact with the flame arrestor core.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] In this invention, after the flame arrester is installed on the corresponding pipeline, the medium in the pipeline enters the sleeve. Then, under the action of the collecting hood, the contact area between the filter frame and the medium is further increased. The gas medium drives the filter frame to move towards the flame arrester core. Impurities in the gas medium are filtered through filter screens A, B, and C, thereby reducing the risk of flame arrester core blockage. When the pipeline stops supplying gas, the filter frame is reset under the action of the spring, and filter screens A and B are cleared by the unblocking cone to ensure that the subsequent gas medium can continue to be filtered.

Detailed Implementation

[0026] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a flame arrestor for an anti-clogging heating furnace, comprising: a flame arresting component 1, an anti-clogging component 2 installed inside the flame arresting component 1, the flame arresting component 1 including a sleeve 11, a connector 12 installed on the sleeve 11, two sets of mating sleeves 13 fixedly connected to the outer surface of the sleeve 11, bolts 14 installed on the mating sleeves 13, a nut A15 threadedly connected to one end of the bolts 14, the two sets of mating sleeves 13 being installed together by the bolts 14 and the nuts A15, a flame arresting core 16 being provided inside the sleeve 11, and the anti-clogging component 2 including a mounting frame 21. Mounting frame 21 is fixedly installed on the inner wall of sleeve 11. Filter screen A22 is installed on mounting frame 21. Filter frame 23 is provided on one side of filter screen A22. Filter screen B24 is installed on filter frame 23. Unblocking cones 25 are installed on both filter screen A22 and filter screen B24. Connecting rod 26 is fixedly connected to one side of filter frame 23. One end of connecting rod 26 extends movably through mounting frame 21 to one side. Nut B27 is threadedly connected to one end of connecting rod 26. Spring 28 is fixedly connected to one side of nut B27. Collection cover 29 is fixedly connected to the other side of filter frame 23.

[0028] First, the entire flame arrester is installed onto the designated pipeline via connector 12. During actual assembly, a branch pipe is also installed on the main pipeline, and a corresponding valve and flame arrester are installed on this branch pipe. This ensures that the entire device can still function normally when one set of flame arresters is disassembled or replaced. When other media in the pipeline enter the sleeve 11 through connector 12, the pressurized gas medium pushes the filter frame 23 and filter screen B24 towards the flame arrester core 16. Then, under the action of the collection hood 29, the contact area between the filter frame 23 and the gas medium is further increased. At this time, the connecting rod 26 drives the nut B27 towards the mounting frame. The movement at point 21 ultimately compresses the spring 28 under the combined action of the mounting frame 21 and the nut B27. During this process, the filter screens A22 and B24 filter the gas medium in the sleeve 11, ensuring the cleanliness of the gas medium in contact with the flame arrestor core 16, thereby effectively reducing the possibility of blockage of the flame arrestor core 16. When the gas supply to the pipeline stops, the filter frame 23 moves towards the mounting frame 21 under the action of the spring 28's rebound force. Then, the mounting frame 21 and the filter frame 23 fit together, and when they fit together, the two sets of unblocking cones 25 unblock the filter screens A22 and B24, ensuring that the filter screens A22 and B24 can work normally.

[0029] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a flame arrester for a heating furnace that prevents blockage, wherein the connector 12 is configured in the shape of a frustum, and a flange 121 is fixedly connected to one end of the connector 12, and a plurality of mounting holes are provided on the flange 121.

[0030] By installing flange 121 on connector 12 and opening mounting holes on flange 121, it is easier for operators to install the flame arrester on the designated pipeline, and it also reduces the difficulty of disassembly and cleaning later.

[0031] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: a flame arrester for an anti-clogging heating furnace, wherein the diameter of the mounting frame 21 is larger than the diameter of the filter frame 23, the filter frame 23 does not directly contact the inner surface of the sleeve 11, both filter screens A22 and B24 act on the flame arresting core 16, the mesh diameter of filter screen A22 is larger than the mesh diameter of filter screen B24, filter screen A22 is close to the input end of the flame arrester, filter screen B24 is disposed between filter screen A22 and the flame arresting core 16, filter screens A22 and B24 are staggered, the unblocking cone 25 installed on filter screen A22 corresponds to the filter hole on filter screen B24, the unblocking cone 25 installed on filter screen B24 corresponds to the filter hole on filter screen A22, the collecting cover 29 is set as a semi-circle, the collecting cover 29 has a through hole 291, and a filter screen C292 is installed inside the collecting cover 29.

[0032] When installing the filter frame 23, a wear-resistant ring is also fitted on its outer surface. Since the filter frame 23 does not directly contact the inner surface of the sleeve 11, the stability of the entire device is further improved, preventing the filter frame 23 from scratching the inner surface of the sleeve 11 due to accidental damage during operation. Furthermore, by setting filter screens A22 and B24 with different mesh sizes, the filtration effect of the entire device can be further increased, ensuring the cleanliness of the gas medium inside the sleeve 11. At the same time, a through hole 291 is opened on the collection cover 29 to make it easier for the gas medium to pass through the through hole 291, preventing the through hole 291 from being subjected to excessive force. Additionally, a filter screen C292 is installed inside the through hole 291 to further increase the filtration effect of the entire device.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
