The upper cover and the pedestal are connected through the inner and the outer fences of the explosion relief fences at the upper and the lower ends of the fences. The utility model has the advantages of small size, repeatable use, capacities of extinguishing explosive flame and trapping powder dust, etc.
Description
What the utility model belonged to industrial dust blast usefulness lets out the waterfall device.
Let out waterfall and be a kind of current techique that is used to protect manufacturing mechanism in the technology that has explosion hazard.The blast of existing sealed mode industrial dust is let out the waterfall device and is mainly contained and let out the waterfall film and let out two kinds at waterfall door.But they all can not be held back dust and extinguish explosive flame when letting out waterfall.At present, letting out the existing institute of waterfall Application of membrane and improve, is to add on the basis of letting out the waterfall film that flame is pounced on to collect partly to form, and lets out the waterfall film and often adopts industrial aluminum or Austenitic Stainless Steel, flame is pounced on the centralized procurement filter medium, guards against the tinsel of broken line shape etc. as pottery with holes, slag wool.Have fire-extinguishing function concurrently though let out the waterfall membrane technology through improvement, dust explosion is let out the unlatching of waterfall device and is finished by letting out the waterfall film, costs an arm and a leg and let out the waterfall film, and the time is long easily aging, must regularly replace, will let out the inside that the waterfall film is contained in the flame trapper in addition, whether it breaks, be difficult for finding, bring danger to production sometimes, let out the waterfall film and can not reuse, finish in case let out waterfall, need reinstall, complex process, be an impediment to the continuity of production.And the existing waterfall door of letting out can repeatedly use, but can not pounce on collection flame, and the harmfulness of dust explosion flame is very big, can cause secondary dust explosion or injury staff on every side.
The purpose of this utility model be to provide a kind of can reuse and have the dust explosion fire extinguishing of pouncing on collection flame function let out the waterfall door.
Fire extinguishing of the present utility model let out the waterfall door mainly by base, loam cake, let out the waterfall fence and let out waterfall piston four parts and constitute.
Fig. 1 is a structural representation of the present utility model.
［ 1 ］ base among the figure, ［ 2 ］ loam cake, ［ 3 ］ let out the waterfall fence, ［ 4 ］ let out the waterfall piston, ［ 5 ］ are let out waterfall piston opening pressure and are set up system, and ［ 6 ］ set up nut, ［ 7 ］ set up spring, ［ 8 ］ pressure rod, ［ 9 ］ pressurizing nut, ［ 10 ］ let out waterfall piston self-locking mechanism, ［ 11 ］ position-arresting anchor, ［ 12 ］ spring, ［ 13 ］ nut, ［ 14 ］ are let out waterfall lid, ［ 15 ］ guide post, ［ 16 ］ locating slot, ［ 17 ］ internal layer fence, ［ 18 ］ gross porosity steel wire, ［ 19 ］ pore steel wire, ［ 20 ］ filter medium, ［ 21 ］ outer fence, ［ 22 ］ garden ring, ［ 23 ］ buffer, ［ 24 ］ connecting bolt, ［ 25 ］ alarm, D is for letting out the waterfall container diameter. Base ［ 1 ］ is the garden shape steel plate of perforate in the middle of, by attachment bolt ［ 24 ］ with let out the waterfall container and connect, base top is welded with garden ring ［ 22 ］, opens the slope at the top of this garden ring and lets out waterfall and cover the wedge-type seal of ［ 14 ］ formation. Loam cake ［ 2 ］ is the garden shape steel plate of perforate in the middle of, covers to be equipped with 2 and to let out waterfall piston opening pressure and set up system ［ 5 ］ and 2 and let out waterfall piston self-locking mechanism ［ 10 ］, and they all are arranged symmetrically with. Let out waterfall piston opening pressure and set up system ［ 5 ］ by setting up nut ［ 6 ］, setting up spring ［ 7 ］, pressure rod ［ 8 ］ and pressurizing nut ［ 9 ］ form, the pressure rod horizontal positioned, the front end of pressure rod is and is line between the inclined-plane of roller shape and pressurizing nut and contacts, set up nut ［ 6 ］ and pressure rod ［ 8 ］ and be the spiral assembling, can be in the upper precession of pressure rod ［ 8 ］, with set pressure. Opening pressure Pstat sets up scope: 0.005MPa～0.05MPa; Let out waterfall piston self-locking mechanism ［ 10 ］ by position-arresting anchor ［ 11 ］, spring ［ 12 ］, nut ［ 13 ］ form, and when letting out waterfall lid ［ 14 ］ and be opened to a certain degree, position-arresting anchor just is located in ［ 16 ］ and locates. Let out the waterfall fence by internal layer fence ［ 17 ］, gross porosity steel wire ［ 18 ］, pore steel wire net ［ 19 ］, filter medium ［ 20 ］ and outer fence ［ 21 ］ form, the inside and outside layer fence of letting out the waterfall fence can adopt bar construction, and filter medium can be selected the on-metallic article materials such as glass fiber, slag wool and goods thereof. The Main Function of letting out the waterfall fence is to extinguish explosive flame and hold back dust. Letting out waterfall piston ［ 4 ］ forms by letting out waterfall lid ［ 14 ］ and guide post ［ 15 ］, let out waterfall lid ［ 14 ］ and be bowl-shape, be connected with guide post ［ 15 ］, the inner lower limb of bowl is equipped with Gask-O-Seal, consist of wedge-type seal, have annular positioning groove ［ 16 ］ on the guide post ［ 15 ］, top and pressurizing nut ［ 9 ］ are threaded engagement. Warning device ［ 25 ］ links with self-locking mechanism ［ 10 ］; Buffer ［ 23 ］ is the garden cylindrical spring, and top is welded on and covers, and guide post passes therebetween. Whole letting out between waterfall door loam cake and the base is threaded by letting out waterfall fence ectonexine fence upper/lower terminal.
Use this practical fire extinguishing to let out the waterfall door, when airtight internal tank generation dust explosion, pressure wave will act on to be let out on the waterfall lid ［ 14 ］, if meeting or exceeding, this active force lets out waterfall piston opening pressure setting system ［ 5 ］ to letting out the setting value of waterfall piston, letting out the waterfall piston opens gun and lets out waterfall lid, let out the waterfall piston in position and let out waterfall piston self-locking mechanism ［ 10 ］ pinning, so that powerful blast pressure continues to release from letting out the waterfall mouth, dust and flame are fired and are not fired in having of blast ejection, dust can be let out the in-built filter medium of waterfall fence and be trapped in and let out waterfall door inside, flame also extinguishes because of the fire extinguishing function of cooling and filter medium, when letting out waterfall, the action of self-locking mechanism causes open alarming device ［ 25 ］, thereby the alarm signal of sounding, remind the staff that it is in time resetted, in order to let out waterfall preparation for blast next time performs.
Further specify content of the present utility model with embodiment below:
15 liters of Hartman explosive assemblys of modified model to let out waterfall Jiong diameter D be 120mm, a blast jar maximum explosion pressure that allows is 1.0MPa, waterfall door design parameter is let out in the fire extinguishing that is applied under this condition: as requested maximum allows explosion pressure and the given waterfall area of letting out to set this fire extinguishing to let out the cracking pressure of waterfall door be 0.02MPa, the elasticity coefficient K=20kg/m of selected pressure setting spring, the last hypotenuse angle of pressurizing nut is 45 °, the centre hole of base diameter is 120mm, filter medium is selected 5 layers of glass fibre cloth for use, gross porosity steel wire aperture is 10mm * 10mm, pore steel wire aperture is 1.5mm * 1.5mm, letting out waterfall fence height is 190mm, its internal diameter is 130mm, in, outer fence adopts bar construction, and the internal layer fence selects for use φ 6 garden steel to surround.
It is little to the utlity model has volume, reusable, can extinguish explosive flame, holds back the advantages such as dust.
