Dust such as small particles of QfJ melting metal, that is, spatter, is heated to a temperature exceeding 100 (lCt) from alooU due to the heat caused by the arc and gas flame.
Distributed within two intestines. Of these, the powder diameter is 0.1μ
The dust of 10μm to 20μm can still be filtered out by careful filtering using bag filters, etc.
It is effective to pack the dust in the range of 1 using an inertial force machine such as a louver type or a centrifugal force machine such as a cyclone type.

果じん機を使用することができる。As a filter cloth material until filtration dust, the maximum continuous use temperature of the sieve is 2.
Since the glass fiber temperature is 50C, most of the materials used are nylon or Tetron with a maximum continuous temperature of 110C to 150C.However, as mentioned above, the temperature of the dust ranges from several 100C to over 1000C. As a result, filter cloths made of nylon or tetron may burn out, reducing the efficiency of the filter.In addition, the amount of heat held by individual dust particles and the amount of heat that dust reaches from the source to the filter cloth may decrease. As a result of considering the amount of time it would take, we found that if we first collect dust with a particle size of 50 μm or more using an inertial force dust collector or centrifugal force dust collector, and then use a filtration dust collector, the dust can be reduced. It is possible to lengthen the time from when the dust is generated to when it reaches the filtration and dust multiplier.Therefore, when dust is generated, the temperature of the dust, which exceeds 1000C from several 100C, decreases in the casing to a temperature close to room temperature. It is possible to prevent burnout of the filter cloth made of nylon or tetron, which is similar to filtration dust, and also to remove dust with a particle size of 50 μm or more using an inertial force dust collector or centrifugal force dust collector, and to reduce the particle size by using a filtration dust collector. Since dust of 50 μm or less is collected, a dust extractor that matches the particle size of the dust to be collected can be used.

ている。For example, when Louva Kataji's inertia force machine is made smaller to reduce the installation area and installation cost, the gas flow rate inside the machine becomes faster and the collected dust is scattered, increasing the efficiency of the machine. descend. In addition, for example, a cyclone-type dust extractor has a dusting efficiency of 85% to 95% and a relatively low pressure loss of 60% to 80%, but the installation height is relatively low. The price is high for a coarse dust filter used for pre-treatment of a dust filtration machine. Therefore, in the past, straight flow type cyclones, tangential flow type cyclones, etc. have been used as modifications of the cyclone type centrifugal force dust control.

In FIG. 1, the straight flow type cyclone is a horizontal cyclone, and the central axis X--X of the outer cylinder 3 is horizontal. A gas inlet 1 is provided at one end of the outer cylinder 3, and a guide vane 5 for imparting swirling motion to the inflowing gas is fixed to a fixed shaft 6. A dust box 7 is provided at the bottom of the other end of the outer cylinder 3, and a dust box 7 is provided at the bottom of the other end of the outer cylinder 3.
An inner cylinder 4 whose axis coincides with the axis X-X of There is. With this configuration, the dust-containing gas flowing in from the gas inlet 1 is given a swirling motion by the guide vanes 5. Therefore, the dust contained in the gas is pressed against the inner wall of the outer cylinder 3 by the centripetal force, moves to the other end of the outer cylinder according to the gas flow, falls into the dust box 7, and is accumulated. . On the other hand, the clean gas from which dust has been separated travels from the guide vane 5 in the direction of the inner cylinder 4 while being rotated by the guide vane 5, passes through the inner cylinder 4, and exits from the gas outlet 2 through the grinding and IIJF cutting. Exposed outside the workshop or welding area.

ス流出口2と連結されている。In FIG. 2, the tangential flow type cyclone is a vertical cyclone, and the central axis X--X of the outer cylinder 3 is vertical. At the upper end of the outer cylinder 3, the inflow direction of the inflow gas is
The gas inlet 1 is opened so as to coincide with the direction of the contact edge. - Also, a turning circle m8 is attached whose axis coincides with the axis XX of the outer cylinder 3, and serves as the center of rotation when the gas flowing in from the gas inlet 1 turns. A dust box 7 and an inner cylinder 4 whose axis coincides with the axis XX of the outer cylinder 3 are provided at the lower end of the outward facing 3. It is connected to a gas outlet 2 which is open to the outdoors.

作業場の屋外に排出される。With this configuration, the dust-containing gas that has flowed from the gas inlet 1 in the direction in which the cylinder 3 is attached is rotated around the center of the rotating cylinder 8f. Therefore, the dust contained in the gas is pressed against the inner wall of the outer cylinder 3 by the centripetal force, and moves to the -F end of the outer cylinder 3 according to the action of gravity and the flow of gas, and is moved to the -F end of the outer cylinder 3. It falls and accumulates inside the pouch. On the other hand, the clean gas from which the dust has been separated travels in the direction of the inner cylinder 4 while being swirled, passes through the entire inner cylinder 4, and is discharged from the gas outlet 2 to the outdoors of the polishing or grinding workshop or the bathing workshop.

飛散現象によって、果しん効率が低下する欠点がおる。As mentioned above, the straight flow type cyclone and the tangential flow type Zyclone have simple structures, but the inflow gas is more than 10 meters /
Since it flows into the housing inner cylinder 4 at a rotation speed of s, the pressure loss is 150 tranH20, which is a disadvantage. Further, when a part of the gas that has progressed while swirling on the inner wall of the external teeth 3 reaches the bottom of the dust box 7 and turns around, a so-called re-scattering phenomenon occurs in which the dust accumulated in the dust box 7 is left behind. The disadvantage is that the efficiency of the process is reduced.

じん効率を尚めることを特徴とするものである。This invention is based on the swirling of offshore gas from which dust is separated by centripetal force. l! - By stopping the dust rotation prevention plate after several intervals, the increase in pressure loss is completely suppressed, and the clean gas from which dust has been separated is prevented from flowing into the dust box. By attaching a plate to prevent the dust from being scattered again, the dust multiplication efficiency can be improved.
