Description

Technical Field

[0001] The utility model relates to the field of flameless venting devices, in particular to a dust flameless venting device with high flow rate. Background Art

[0002] With the development of modern industry, the potential danger of dust explosion has increased greatly. When mixed with air during processing, handling or storage operations, the explosion can cause the ignition of combustible gases, mists or dusts, resulting in a rapid pressure rise in a closed structure. At the same time, if there is not enough strength to withstand the deflagration pressure, it will cause heavy losses and casualties. Therefore, a dust flameless venting device with high flow rate is needed.

[0003] In the existing dust flameless venting devices, in order to ensure high flow rate, structural treatments for preventing ash accumulation and blockage are usually carried out to ensure the smoothness of the pipeline. After the dust flameless venting device vents, dry dust usually remains in the device, and there are still unextinguished dusts mixed in it, which is easy to cause secondary explosion. Moreover, the device is usually located in an environment with a large amount of dust, and a large amount of dust will accumulate on the explosion-proof plate, affecting the heat dissipation effect of the explosion-proof plate, thus affecting the venting effect of the device. Therefore, the utility model provides a dust flameless venting device with high flow rate to solve the problems raised in the above background art. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a dust flameless venting device with high flow rate is proposed. The device can mix the residual dust in the device with water to prevent secondary explosion, and can quickly clean the explosion-proof plate, so that dust blockage of the explosion-proof plate will not affect the heat dissipation effect during long-term placement. At the same time, the first fixed box and the second fixed box can be disassembled through a connecting plate for easy maintenance.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes a first fixed box and a second fixed box. A gas inlet is penetratively opened at the center of one side of the first fixed box. A water tank is fixedly arranged at the center of the upper end surface of the second fixed box. An atomizing nozzle is fixedly arranged at the center of the lower end surface of the water tank. An explosion-proof plate is fixedly arranged on one side of the second fixed box. Fixing plates are fixedly arranged at the outer sides of the explosion-proof plate near the front and rear ends. Card slots are penetratively opened at the centers of the front end faces of the two fixing plates. A cleaning mechanism is clamped in the two card slots. The cleaning mechanism includes two sliding pieces, a cleaning roller and two fixing blocks.

[0006] At the lower end surfaces of the inner walls of the first fixed box and the second fixed box near one side, installation grooves are respectively opened. At the centers of both sides of the inner walls of the two installation grooves, clamping grooves are respectively opened. At the upper end surfaces of the inner walls of the first fixed box and the second fixed box near one side, elastic return grooves are respectively opened. Springs are fixedly arranged in the two elastic return grooves. In the elastic return groove located in the first fixed box among the two elastic return grooves, a second fireproof board is movably clamped. In the elastic return groove located in the second fixed box among the two elastic return grooves, a first fireproof board is movably clamped;

[0007] Through the above technical solution, the atomizing nozzles added in the second fixed box can quickly settle the dust escaping in the device, reduce the probability of secondary deflagration, and at the same time can cool the inside of the device to extend the service life of the device. And the cleaning mechanism is used to clean the mesh holes on the surface of the explosion-proof board to prevent dust from blocking the mesh holes and affecting the discharge effect of the device.

[0008] Further, a plurality of cleaning columns are fixedly arranged on the outer wall of the cleaning roller. Bearings are respectively embedded at the centers of both sides of the cleaning roller. Connecting shafts are fixedly arranged in the two bearings. Two fixing blocks are respectively fixedly arranged on the opposite sides of the two connecting shafts. Two sliding pieces are respectively fixedly sleeved at the centers of the two fixing blocks. An operating rod is fixedly arranged on one side of one of the two fixing blocks;

[0009] Through the above technical solution, the cleaning roller can be driven to roll on the surface of the explosion-proof board by the operating rod, and the explosion-proof board is cleaned by the cleaning columns on the outer wall of the cleaning roller being inserted into the mesh holes.

[0010] Further, connecting plates are respectively fixedly arranged on the opposite sides of the first fixed box and the second fixed box. Through holes are respectively opened at the four corners near one side of the two connecting plates. In the two through holes located on the same horizontal line among the eight through holes, threaded rods are respectively slidably sleeved. Handles are respectively fixedly arranged on one sides of the four threaded rods. Nuts are respectively threaded on the outer walls of the other sides of the four threaded rods;

[0011] Through the above technical solution, the first fixed box and the second fixed box can be disassembled, which is convenient for maintaining and cleaning the inside of the device.

[0012] Further, a plurality of limiting rods are respectively fixedly arranged on both sides of the two installation grooves in the first fixed box and the second fixed box. The atomizing nozzle penetrates through the upper end surface of the second fixed box;

[0013] Through the above technical solution, the design of the limiting rods facilitates providing an installation track for the disassembly of the first fireproof board and the second fireproof board without affecting the flow rate.

[0014] Furthermore, sliding grooves are provided at the centers of the upper and lower end faces of the inner walls of the two card slots, and the two sliding plates are respectively slidably clamped in the two sliding grooves;

[0015] Through the above technical solution, the position of the cleaning mechanism can be restricted, so that the cleaning mechanism can roll closely against the surface of the explosion-proof plate.

[0016] Furthermore, the central materials of the first fireproof plate, the second fireproof plate and the explosion-proof plate are all wire meshes, and the aperture of the wire mesh on the first fireproof plate is smaller than the aperture of the wire mesh on the second fireproof plate;

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment

[0032] Refer to Figures 1-5 , an embodiment provided by the present utility model: including a first fixing box 1 and a second fixing box 5. An air inlet 12 is penetrated and opened at the center of one side of the first fixing box 1. A water tank 9 is fixedly arranged at the center of the upper end surface of the second fixing box 5. An atomizing nozzle 18 is fixedly arranged at the center of the lower end surface of the water tank 9. The atomizing nozzle 18 can atomize and spray the water in the water tank 9, which can increase the contact area between water and dust and improve the dust reduction effect. An explosion-proof plate 6 is fixedly arranged on one side of the second fixing box 5. Fixing plates 7 are fixedly arranged on both sides of the explosion-proof plate 6 near the front and rear ends. Card slots 16 are penetrated and opened at the centers of the front end surfaces of the two fixing plates 7. A cleaning mechanism 8 is clamped and arranged in the two card slots 16. The cleaning mechanism 8 can quickly clean the surface of the explosion-proof plate 6 to prevent the mesh holes on the surface of the explosion-proof plate 6 from being blocked by dust and affecting the discharge effect of the explosion-proof plate 6. The cleaning mechanism 8 includes two slide pieces 802, a cleaning roller 805 and two fixed blocks 807;

[0033] The first fixed box 1 and the second fixed box 5 are each provided with an installation groove 14 at one side of the lower end surface of the inner wall, and the two installation grooves 14 are each provided with a snap-in groove 15 at the center of both sides of the inner wall. The first fixed box 1 and the second fixed box 5 are each provided with a rebound groove 20 at one side of the upper end surface of the inner wall, and springs 17 are fixedly arranged in the two rebound grooves 20. A second fireproof plate 22 is movably snap-fitted in the rebound groove 20 located in the first fixed box 1, and a first fireproof plate 21 is movably snap-fitted in the rebound groove 20 located in the second fixed box 5.

[0034] When deflagration occurs, the burning dust enters the first fixed box 1 along the air inlet 12 and weakens the intensity of a part of the shock wave through the No. 2 fireproof plate 22 in the first fixed box 1, preventing the shock wave from damaging the atomizing nozzle 18 and affecting the use of the atomizing nozzle 18. The burning dust enters the second fixed box 5 and is blocked by the design of the No. 1 fireproof plate 21 for most of the dust, limiting the dust between the No. 1 fireproof plate 21 and the No. 2 fireproof plate 22. Then, the water in the water tank 9 is atomized and sprayed out through the atomizing nozzle 18, which can increase the contact area between water and dust so that the water mist can adsorb the dust. At the same time, the dust that has not been completely extinguished can be extinguished to prevent secondary deflagration in the device. Then a small part of the wet dust and high-pressure gas are discharged along the explosion-proof plate 6.

[0035] Since the device is placed in a space with a high dust density for a long time, dust usually adheres to the surface of the explosion-proof plate 6. When the dust blocks the mesh holes on the surface of the explosion-proof plate 6, the operating rod 801 is pulled to drive the fixed block 807 to slide along the card slot 16. At the same time, the slide 802 is embedded in the slide slot 23 to limit the range of movement of the fixed block 807. The cleaning roller 805 is driven to slide along the surface of the explosion-proof plate 6 by the fixed block 807 and the connecting shaft 806. At the same time, the design of the bearing 803 enables the cleaning column 804 to rotate when it is embedded in the mesh holes on the explosion-proof plate 6, so that the next group of cleaning columns 804 can be embedded in the explosion-proof plate 6 to clean the mesh holes on the surface of the explosion-proof plate 6, so as to prevent the mesh holes from being blocked by dust and affecting the discharge effect of the device.

[0036] When cleaning the inside of the device, first pull out the two positioning blocks 3 along the snap-in groove 15, and the spring 17 makes the No. 1 fireproof board 21 and the No. 2 fireproof board 22 pop out from the rebound groove 20, and then the replaced No. 1 fireproof board 21 and the No. 2 fireproof board 22 are respectively embedded in the second fixed box 5 and the first fixed box 1 along the two installation grooves 14, and the No. 1 fireproof board 21 and the No. 2 fireproof board 22 can be embedded in the rebound groove 20 through the design of multiple limit rods 13, and then the two positioning blocks 3 are embedded in the installation groove 14 along the two snap-in grooves 15, and then the nuts 4 and the threaded rods 10 are removed through the handle 11 along the screw holes 19 opened at the four corners of the connecting plate 2, so as to facilitate cleaning of the first fixed box 1 and the second fixed box 5.

[0037] Working principle: The cleaning mechanism 8 is used to clean the mesh holes on the surface of the explosion-proof plate 6, preventing the mesh holes from being blocked by dust and affecting the discharge effect of the device. Most of the dust can be restricted between the second fireproof plate 22 and the first fireproof plate 21 through their designs, and then the dust is adsorbed by the water mist sprayed by the atomizing nozzle 18, preventing secondary deflagration of the dust inside the device and achieving the effect of quickly cooling the interior of the device.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
