Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, in particular to a high-pressure explosion-proof bag filter. Background Technique

[0002] During industrial production processes, a large amount of dust and particulate matter are generated, which pose a serious threat to the environment and human health. To effectively remove these pollutants, bag filters, as efficient dust removal equipment, have been widely used. During the use of bag filters, dust accumulation and dust ignition can both cause an increase in internal pressure, which may further lead to an explosion; in practical applications, bag filters usually require the following technologies:

[0003] 1. A sturdy dust collector box body for isolating the internal and external spaces, enabling dust to be filtered inside the dust collection box body.

[0004] 2. Optimized airflow distribution design technology to make the dust-containing gas pass through the filter bags evenly, reducing local resistance and wear, and improving the overall dust removal effect.

[0005] 3. A stable pressure relief mechanism that can relieve pressure in a timely manner when the internal pressure of the box body is too high, preventing the box body from exploding due to excessive pressure.

[0006] The existing Chinese patent: An explosion-proof dust high-pressure explosion-proof bag filter, publication number: CN214914325U, includes a box body, a pressure relief device is installed on the box body, the pressure relief device includes a mounting frame and a pressure relief cover, a pressure relief mechanism is arranged inside the mounting frame, the pressure relief mechanism includes a pressure relief pipe and a driving component, the pressure relief pipe is rotatably connected to the mounting frame, a turntable is sleeved on the outer wall of the other end of the pressure relief pipe, a connecting plate is installed on the outer wall of the turntable, six oblong holes are evenly distributed on the turntable, and a sliding rod is slidably connected in the oblong holes. The utility model controls the rotation of the turntable through the driving component, drives the sliding rod to slide in the oblong holes by using the turntable, drives the baffle to move outwards or inwards by using the sliding rod, and exposes or blocks the pressure relief pipe by using the baffle moving outwards or inwards, so as to effectively avoid the situation of explosion caused by excessive air pressure in the box, and reduce the potential safety hazard.

[0007] However, during the implementation of the above technical solution, it is found that at least the following technical problems exist: The above high-pressure explosion-proof bag filter relies on a pressure sensor to detect the pressure. When the detected pressure is too high, the pressure relief pipe is driven by a motor to be opened for pressure relief to avoid explosion. However, if an electric spark generated by electronic components such as a motor appears inside the dust collector, it will quickly ignite the internal dust, and its ignition speed is relatively fast, which will cause the internal pressure to rise rapidly. And the above pressure relief structure of the dust collector is complex and the response speed is slow. When the internal dust explodes and burns, it cannot quickly discharge the pressure, which may further lead to the explosion of the box body. Summary of the Utility Model

[0008] (1) Technical problem to be solved

[0009] In view of the deficiencies of the prior art, the present utility model provides a high-pressure explosion-proof bag-type dust collector. For the above-mentioned high-pressure explosion-proof bag-type dust collector, the pressure is detected by a pressure sensor. When the detected pressure is too high, the pressure relief pipe is driven by a motor to open for pressure relief to avoid explosion. However, if an electric spark generated by electronic components such as a motor appears inside the dust collector, it will quickly ignite the internal dust, and its ignition speed is relatively fast, which will cause the internal pressure to rise rapidly. Moreover, the above-mentioned pressure relief structure of the dust collector is complex and the response speed is slow. When the internal dust explodes and burns, the pressure cannot be quickly discharged, which may lead to the explosion of the box body.

[0010] (2) Technical solution

[0011] To achieve the above objectives, the present utility model is realized through the following technical solutions:

[0012] A high-pressure explosion-proof bag-type dust collector includes a dust collector main body. An explosion relief pipe is fixedly installed on the dust collector main body. Explosion relief doors are rotatably installed symmetrically on the explosion relief pipe. A water storage bag is fixedly installed on the explosion relief door. A nozzle is fixedly installed inside the explosion relief door. Pressing plates are fixedly installed symmetrically on the explosion relief pipe. A pressure relief strip is installed on the explosion relief pipe through bolts. A quick break is provided in the middle of the pressure relief strip. Bent openings are symmetrically provided at both ends of the pressure relief strip; the dust collector main body is communicated with the explosion relief pipe, the water storage bag is communicated with the nozzle, the water storage bag is filled with water, a pressure relief pipe is fixedly installed on the dust collector main body, a pressure relief cone is slidably installed inside the pressure relief pipe, a spring is installed on the outer side wall of the pressure relief cone, and a screw cap is installed on the pressure relief pipe.

[0013] Preferably: A threaded sleeve is rotatably installed on the screw cap; the threaded sleeve is threadedly connected to the pressure relief pipe.

[0014] Preferably: A sealing gasket is fixedly installed at the bottom end of the pressure relief cone.

[0015] (3) Beneficial effects

[0016] First, a quick break is provided in the middle of the pressure relief strip. Therefore, when the dust inside the dust collector main body is ignited by a spark, the pressure relief strip can be quickly squeezed and broken, thereby opening the two explosion relief doors for pressure relief. At the same time when the explosion relief doors are opened, the water storage bag is squeezed and will also spray the escaping flame, achieving the effect of quickly relieving pressure when the dust is ignited and avoiding the explosion of the dust collector main body.

[0017] Second, after the pressure relief is completed, a new pressure relief strip can be installed to resume use. Not only is the pressure relief cost low, but it can also be quickly restored to use after pressure relief. By replacing the spring, the internal pressure of the dust collector main body can be adjusted. The structure is simple, the operation is stable, and the reliability is higher.

[0027] Embodiments of the present application provide a high-pressure explosion-proof bag filter, effectively solving the technical problem of the above-mentioned high-pressure explosion-proof bag filter. The pressure is detected by a pressure sensor, and when the detected pressure is too high, the pressure relief pipe is driven by a motor to open for pressure relief to avoid explosion. However, if electric sparks generated by electronic components such as motors appear inside the dust collector, the internal dust will be quickly ignited, and its ignition speed is relatively fast, which will cause the internal pressure to rise rapidly. The pressure relief structure of the above-mentioned dust collector is complex and the response speed is slow. When the internal dust explodes and burns, the pressure cannot be quickly discharged, which will lead to the explosion of the box body. A quick-break port is provided in the middle of the pressure relief strip. Therefore, when the dust inside the dust collector main body is ignited by a spark, the pressure relief strip can be quickly squeezed and disconnected, thereby opening two explosion relief doors for pressure relief. At the same time when the explosion relief doors are opened, the water storage bag is squeezed and will also spray the escaping flame, achieving the effect of quickly relieving pressure when the dust is ignited to avoid the explosion of the dust collector main body. After the pressure relief is completed, a new pressure relief strip can be installed to resume use. Not only is the pressure relief cost low, but it can also be quickly restored to use after pressure relief. By replacing the spring, the internal pressure of the dust collector main body can be adjusted. The structure is simple, the operation is stable, and the reliability is higher.

[0028] Embodiment

[0029] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in

[0030] In view of the problems existing in the prior art, the present utility model provides a high-pressure explosion-proof bag filter, which includes a dust collector main body 1, an explosion relief pipe 2 is fixedly installed on the dust collector main body 1, explosion relief doors 3 are symmetrically and rotatably installed on the explosion relief pipe 2, a water storage bag 4 is fixedly installed on the explosion relief doors 3, a nozzle 5 is fixedly installed inside the explosion relief doors 3, and extrusion plates 6 are symmetrically and fixedly installed on the explosion relief pipe 2.

[0031] A pressure relief strip 7 is installed on the pressure relief pipe 2 through bolts. A quick-break port 8 is provided in the middle of the pressure relief strip 7, and bent ports 9 are symmetrically provided at both ends of the pressure relief strip 7; the dust collector main body 1 is communicated with the pressure relief pipe 2, the water storage bag 4 is communicated with the nozzle 5, the water storage bag 4 is filled with water, and a pressure relief pipe 11 is fixedly installed on the dust collector main body 1.

[0032] A pressure relief cone 12 is slidably installed inside the pressure relief pipe 11. A spring 13 is installed on the outer side wall of the pressure relief cone 12. A screw cap 14 is installed on the pressure relief pipe 11, and a threaded sleeve 15 is rotatably installed on the screw cap 14; the threaded sleeve 15 is threadedly connected with the pressure relief pipe 11, and a sealing gasket 16 is fixedly installed at the bottom end of the pressure relief cone 12.

[0033] Working principle:

[0034] First step, during use, if the internal pressure rises slowly, when the internal pressure is greater than the elastic force of the spring 13, it will push the pressure relief cone 12 to slide upward against the elastic force of the spring 13. When the pressure relief cone 12 drives the sealing gasket 16 to slide upward and leave the top opening of the pressure relief pipe 11, the pressure inside the dust collector main body 1 will be discharged along the top opening of the pressure relief pipe 11 until the internal pressure of the dust collector main body 1 is less than the elastic force of the spring 13. The pressure relief cone 12 will be pushed by the elastic force of the spring 13 to block the top opening of the pressure relief pipe 11 again. When it is necessary to adjust the internal pressure of the dust collector main body 1, the threaded sleeve 15 can be rotated and then the screw cap 14 can be removed. The pressure relief cone 12 and the spring 13 are taken out, and then the spring 13 on the outer side wall of the pressure relief cone 12 is replaced with a spring 13 of other specifications. The greater the elastic force of the spring 13, the greater the internal pressure of the dust collector main body 1 will be, and the smaller the elastic force of the spring 13, the smaller the internal pressure of the dust collector main body 1 will be. After the spring 13 is replaced, the pressure relief cone 12, the spring 13 and the screw cap 14 are reinstalled, and then the threaded sleeve 15 is tightened.

[0035] Second step, a quick-break port 8 is provided on the pressure relief strip 7, such that the pressure that the pressure relief strip 7 can withstand is less than the pressure that the dust collector main body 1 can withstand. Therefore, if a spark appears inside, it will quickly ignite the dust inside the dust collector main body 1, causing the pressure inside the dust collector main body 1 to increase rapidly. However, the opening of the pressure relief pipe 11 is small and cannot relieve pressure quickly. At this time, the pressure inside the dust collector main body 1 will push the two explosion relief doors 3. The two explosion relief doors 3 exert pressure on the pressure relief strip 7, which will break the pressure relief strip 7 at the quick-break port 8. After the quick-break port 8 is disconnected, the pressure relief strips 7 on both sides will bend outward along the bending port 9. During this process, the two explosion relief doors 3 will continue to rotate and open towards both ends. The pressure inside the dust collector main body 1 will also be discharged along the opening where the explosion relief doors 3 open. At the same time, during the process of the explosion relief doors 3 rotating towards both ends, the water storage bag 4 will be squeezed by the explosion relief doors 3 and the pressing plate 6. After the water storage bag 4 is squeezed, the water inside will be quickly sprayed out along the nozzle 5. Therefore, when the explosion relief doors 3 open to relieve pressure, the water storage bag 4 will also spray the escaping flame at the same time. This can not only quickly relieve the pressure inside the dust collector main body 1 to avoid dust explosion, but also reduce the harm of the escaping flame. When the equipment is repaired again, rotate the two explosion relief doors 3 back to their original positions, and then take out a new pressure relief strip 7 and install it with bolts to restore normal use again.

[0036] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
