Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the powder discharging device described in Patent Document 1, when guiding crushed materials such as glass and pottery instead of powder particles, the flexible sheet is immediately broken and cannot be used.

[0006] In addition, when the shooter (cylindrical body) has a hole and the shooter needs to be replaced, first, the connection with the frame that fixes the shooter is released, and the shooter needs to be lifted using a heavy machine and then replaced with a new shooter, which requires time and effort.

[0007] Therefore, the present invention, in view of the above circumstances, aims to provide a method for safely replacing the chute of a cyclone chute with less burden on the worker, and to provide a cyclone chute. [Means for solving the problem]

[0008] The present invention relates to a method for replacing the chute of a cyclone chute, which is inserted into a recovery section, wherein the cyclone chute comprises a cyclone section fixed to a frame, a chute section inserted into an insertion port of the recovery section, and a spacer section having a thickness greater than the insertion depth of the chute section into the recovery section and located between the cyclone section and the chute section, and the chute is connected to the cyclone section, the method being characterized by sequentially performing the following steps: a separation step of releasing the connection and separating the cyclone section, the chute section, and the spacer section; a first removal step of removing the spacer section; a second removal step of removing the chute section from the insertion port using the gap formed by the first removal step; a first intake step of taking in a new chute section and inserting it into the insertion port; and a second intake step of taking in the spacer section between the new chute section and the cyclone section.

[0009] The cyclone chute according to the present invention comprises a cyclone section fixed to a frame, a chute section inserted into the insertion port of a collection section, and a spacer section located between the cyclone section and the chute section. The cyclone section, the chute section, and the spacer section are each divisibly connected, and the thickness of the spacer section is greater than the insertion depth of the chute section into the collection section.

[0010] Furthermore, the length from the lower end of the cyclone section to the insertion port is longer than the height of the new chute section. [Effects of the Invention]

[0011] According to the present invention, in a cyclone chute in which a cyclone section, a chute section, and a spacer section are connected, after disconnecting the connection and separating the components, the spacer section is removed, creating a gap equal to the size of the spacer section. Since this gap is thicker than the insertion depth of the chute section into the collection section, the chute section can be removed and replaced with a new chute section.

[0012] Furthermore, it has a cyclone section fixed to the frame, a chute section that is inserted into the insertion port of the collection section, and a spacer section located between the cyclone section and the chute section. The cyclone section, chute section, and spacer section are each detachably connected, and the thickness of the spacer section is greater than the insertion depth of the chute section into the collection section. By removing the spacer section, the gap created allows the chute section to be removed and replaced with a new chute section.

[0013] Furthermore, since the length from the bottom end of the cyclone section to the insertion port is longer than the height of the chute section and the new chute section, the chute section can be removed and the new chute section can be installed. [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0015] Hereinafter, with reference to the drawings, the cyclone shooter 100 according to the present invention and the shooter replacement method of the cyclone shooter 100 will be described in detail.

[0016] [Regarding the Cyclone Shooter 100] The cyclone shooter 100 is provided in a crushing facility such as a pottery or a glass mat. The pottery or glass mat that has been crushed by a crusher into dust is sucked into a dust collector through a flow path L, and heavy fragments fall into a lower recovery section 60 and are recovered by the cyclone shooter 100. Thereby, before the dust is sucked into the dust collector, clogging of the filter of the dust collector is prevented.

[0017] The cyclone shooter 100 in the present embodiment mainly includes a cyclone section 10, a shooter section 20, and a spacer section 30. [End]]

[0018] [End]] [End]](Regarding the Cyclone Section [End]]The cyclone section 10 is fixed to a frame 40 around it, the upper part is connected to the flow path L, and it sends fragments to the shooter section to be described later, which is located below. Heavy fragments flow into the cyclone section 10, and dust and powder-like substances pass horizontally without falling into the cyclone section 10 and flow through the flow path L. [End]]

[0019] [End]] [End]]As shown in FIGS. 1 and 2, the cyclone section 10 has a cylindrical shape with a hollow interior, and has a tapered section 11 that tapers downward and a first flange section 12. [End]]

[0020] [End]] [End]]The tapered portion 11 includes an upper tapered portion 11a and a lower tapered portion 11b that can be split from each other. The upper tapered portion 11a has its upper end connected to the flow path L and has an upper flange portion 11c extending horizontally at its lower end. The lower tapered portion 11b also has a lower flange portion 11d at its upper end, and by connecting the upper flange portion 11c and the lower flange portion 11d, the upper tapered portion 11a and the lower tapered portion 11b can be connected and fixed.

[0021] At the lower end of the lower tapered portion 11b, in order to connect to the shooter portion 20, it has a first flange portion 12 extending horizontally. The first flange portion 12 is provided with insertion holes for inserting a connecting member 50 such as a bolt at regular intervals. As shown in FIG. 2, the distance H2 from the first flange portion 12, which is the lower end of the cyclone portion 10, to the insertion port 61 of the recovery portion 60 is formed to be shorter than the sum of the height H3 of the shooter portion 20 and the thickness H1 of the spacer portion 30. Thereby, the shooter portion 20 can be inserted into the insertion port 61 of the recovery portion 60, so that the falling debris will not fly out sideways.

[0022] In this embodiment, the tapered portion 11 is assumed to be divided into an upper tapered portion 11a and a lower tapered portion 11b, but it may also be an integrally formed type instead of being divided. Also, the shape of the tapered portion 11 does not have to be a tapered shape. As long as it is a plug-in type, it may be cylindrical, and the configuration, shape, etc. are not particularly limited.

[0023] (Regarding the shooter portion 20) The shooter portion 20 feeds the heavy debris sent from the cyclone portion 10 into the recovery portion 60. As shown in FIG. 2, the shooter portion 20 has a cylindrical tube portion 21 and a second flange portion 22 extending horizontally at the upper end of the tube portion 21. Although not shown, the second flange portion 22 is provided with insertion holes for inserting a connecting member 50 such as a bolt at regular intervals.

[0024] The area of ​​the insertion port 61 is formed to be larger than that of the cylindrical portion 21 and smaller than that of the second flange portion 22. The lower end of the cylindrical portion 21 is not fixed and is inserted into the insertion port 61 of the recovery portion 60. Even if there are slight dimensional errors during the manufacturing of the chute portion 20 or the cyclone portion 10, the insertion method without fixing the lower end allows for adjustment at the lower end. A sealant 70 is provided to fill the gap between the lower end of the cylindrical portion 21 and the insertion port 61.

[0025] As shown in Figure 2, the height H3 of the chute section 20 is formed to be shorter than the height H2 from the lower end of the cyclone section 10 to the insertion port 61. This eliminates the need to lift the cyclone section 10 upwards using a crane or the like, as will be described later. A new chute section 80 can be incorporated.

[0026] The chute section 20 is located at the bottom and has a small horizontal cross-sectional area, making it easy for heavy fragments to fall with force and hit its inner surface. As a result, the inner surface of the chute section 20 is a component that experiences severe wear.

[0027] The lower end of the chute section 20 is inserted into the insertion opening 61 of the chute section 20, with an insertion depth H4 of approximately 10 mm to 20 mm, preferably 15 mm. As mentioned above, a sealant 70 is provided between the insertion opening 61 and the outer circumference of the chute section 20 to prevent the formation of any gaps.

[0028] The chute section 20 is fixed to the cyclone section 10 only by the second flange section 22 via the spacer section 30, and is not fixed anywhere else. When the fixing of the second flange section 22 is released, the cylindrical section 21 of the chute section 20 is inserted into the insertion port 61, falls down, and gets caught on the insertion port 61 by the second flange section 22.

[0029] (Regarding the spacer part 30) As shown in Figure 2, a disc-shaped spacer portion 30 is provided between the cyclone portion 10 and the chute portion 20. As shown in Figure 6, an insertion hole 31 for inserting a connecting member 50 such as a bolt and a flow hole 32 are provided.

[0030] The position of the insertion hole 31 is such that when the cyclone section 10, spacer section 30, and chute section 20 are stacked, the insertion hole of the first flange section 12 and the insertion hole of the second flange section 22 coincide. In this way, the cyclone section 10, spacer section 30, and chute section 20 are connected together by the connecting member 50. Furthermore, by removing the connecting member 50, the cyclone section 10, spacer section 30, and chute section 20 can be separated, respectively.

[0031] A flow hole 32 for passing fragments is provided approximately in the center of the spacer section 30. The shape and size of the flow hole 32 match the shape and size of the horizontal cross-section of the inner surface of the cyclone section 10 and the chute section 20. This ensures that fragments falling from the cyclone section 10 do not interfere with the chute section 20 and are instead guided to the chute section 20.

[0032] Furthermore, the thickness H1 of the spacer portion 30 is formed to be greater than the insertion depth H4 of the chute portion 20 into the collection portion 60. This allows the chute portion 20 to be removed using the gap D created after removing the spacer portion 30, as will be described later. This makes it possible to remove the chute portion 20 without lifting the cyclone portion 10 upwards, and to replace it with a new chute portion 80.

[0033] It is conceivable to replace the chute section 20 by lifting the cyclone section 10 upwards without using the spacer section 30, but since the lower tapered section 11b of the cyclone section 10 alone weighs about 250 kg, a crane would be required to lift the cyclone section 10 upwards, and it would also be necessary to detach it from the frame 40, which would be labor-intensive and time-consuming.

[0034] Furthermore, since the recovery unit 60 is used to recover fragments and is usually fixed to the ground surface, it is difficult to adjust the height of the recovery unit 60.

[0035] Therefore, when replacing the chute section 20 in the cyclone chute 100, it is only necessary to replace the chute section 20 and the spacer section 30, which together weigh several tens of kilograms. As such, even with a small number of people, no special tools are required, and the replacement can be done easily and safely in a relatively short amount of time.

[0036] (Regarding other implementations) In this embodiment, there is only one spacer 30, but multiple spacers may be provided if necessary. Even if the height of the cylindrical portion 21 of the chute portion 20 changes, this can be accommodated by changing the number of spacer 30s.

[0037] In this embodiment, the cyclone shooter 100 was positioned vertically, but it can be used similarly with a horizontally positioned cyclone shooter.

[0038] [How to replace the shooter on the Cyclone Shooter 100] Next, we will explain how to replace the chute section of the Cyclone Shooter 100. The replacement method includes, in order, a separation step, a first removal step, a second removal step, a first intake step, a second intake step, and a connection step.

[0039] (Regarding the division process) First, as shown in Figure 3(a), a separation process is performed in which the connecting member 50 that connects the cyclone section 10, the spacer section 30, and the chute section 20 is removed, and the cyclone section 10, the spacer section 30, and the chute section 20 are separated. If a sealant 70 is provided between the chute section 20 and the insertion port 61, the sealant 70 is removed before the separation process is performed.

[0040] In this case, the chute section 20 is fixed only to the cyclone section 10 via the spacer section 30, and nothing else is fixed to it. Therefore, after removing all eight connecting members 50, the spacer section 30 is supported to prevent it from falling into the insertion opening 61 of the collection section 60.

[0041] (Regarding the first removal process) Next, after the splitting process, the spacer portion 30 is no longer fixed, so the first removal process can be performed, in which only the spacer portion 30 is moved laterally and removed.

[0042] Since the spacer section 30 weighs approximately 10 kg, it can be easily removed by hand alone, without the use of machinery, while another worker supports the chute section 20 and the spacer section 30.

[0043] Subsequently, when the spacer portion 30 is removed, a gap D is formed equal to the thickness H1 of the spacer portion 30, as shown in Figure 3(b). Also, as mentioned above, the thickness H1 of the spacer portion 30 is formed to be greater than the insertion depth H4 of the chute portion 20.

[0044] (Regarding the second removal process) Therefore, as shown in Figure 4(a), the chute portion 20 can be lifted up using the gap D until it is completely removed from the insertion opening 61, and then, in the same way as the spacer portion 30, it can be moved laterally and removed, thus performing a second removal step. After the second removal step, as shown in Figure 4(b), the spacer portion 30 and the chute portion 20 are absent.

[0045] (Regarding the first intake process) Subsequently, a first insertion process is performed to introduce the new chute section 80. The new chute section 80 has the same shape and structure as the chute section 20, and is a brand new chute section 20 that is free from wear and holes. As shown in Figure 5(a), the height H3 of the new chute section 80 is shorter than the distance H2 from the lower end of the lower tapered section 11b to the insertion opening 61, so the new chute section 80 can be inserted from the side through the gap D.

[0046] After inserting the new chute section 80 from the side, insert the cylindrical section 21 into the insertion opening 61. This creates a gap above the chute section 20 for later inserting the spacer section 30 from the side.

[0047] (Regarding the second intake process) After the first intake process, a second intake process is performed in which the spacer portion 30 is placed on top of the new chute portion 80 and taken in, as shown in Figure 5(b). At this time, the spacer portion 30 is placed so that the insertion hole 31 of the spacer portion 30 and the insertion hole of the second flange portion 22 of the chute portion 20 are aligned.

[0048] (Regarding the consolidation process) After the second intake process, a connecting process is performed again to connect the cyclone section 10, the new chute section 80, and the spacer section 30. When connecting, connecting members 50 such as bolts and nuts are inserted through the insertion holes and secured.

[0049] When connecting the units, first insert only one connecting member 50 through the cyclone section 10, spacer section 30, and chute section 20, and temporarily fasten it in place. With only one member fixed in place, the spacer section 30 and chute section 20 are fixed in an obliquely tilted position.

[0050] Subsequently, while one worker supports the spacer portion 30 and the chute portion 20 so that they are in a horizontal position, another worker inserts the connecting member 50 into the insertion hole on the opposite side of the temporarily fixed location and temporarily fastens it. Once the two connecting members 50 are temporarily fastened, the spacer portion 30 and the chute portion 20 are maintained in a horizontal position.

[0051] After that, the connecting members 50 are temporarily fixed in place through all the insertion holes, and then the connecting members 50 are tightened to complete the connection process.

[0052] The above process completes the replacement of the cyclone chute 100. Conventionally, when replacing the chute 20 by lifting the cyclone unit 10, it was necessary to lift the lower tapered section, which weighs more than 250 kg, after disconnecting the cyclone unit 10 and the chute 20. However, with the method according to the present invention, the chute can be replaced without lifting the cyclone unit 10, only by the burden of disconnecting the cyclone unit 10 and the chute 20.

[0053] Therefore, no special tools are required, and the chute section 20 can be replaced by two workers using only common tools such as wrenches, in a short time of about 30 minutes. In addition, this not only shortens the construction period and reduces costs, but also enhances worker safety. [Explanation of symbols]
