Description

Technical Field

[0001] This application relates to the field of industrial processing technologies, and more particularly to a branch pipe device for reducing the risk of blockage in an exhaust duct. Background Art

[0002] In the existing production and processing of polysilicon, silicon powder particles are leaked to varying degrees. Since the emission of silicon powder into the atmosphere will pollute the environment and endanger human health, in the prior art, dust collectors are used to collect the silicon powder generated in industrial production. Among them, the dust collector is a set of equipment that uses negative pressure to extract the silicon powder generated during the crushing of silicon materials. However, during the extraction of silicon powder, silicon blocks of different sizes will be sucked into the dust removal pipeline together. Because large particles are deposited in the pipeline and are not easily carried away, large particles will block small particles from continuing to deposit behind them, resulting in blockage of the dust removal pipeline. This will cause the suction at the end of the dust removal system to weaken, resulting in poor dust removal effect due to the reduced suction at the end of the dust removal, increasing the silicon dust content in the silicon material and affecting product quality. Utility Model Content

[0003] The purpose of this application is to provide a branch pipe device for reducing the risk of blockage in an exhaust duct.

[0004] To achieve the above object, the technical solution adopted in this application is as follows: A branch pipe device for reducing the risk of blockage in an exhaust duct is provided. The exhaust duct includes a dust outlet interface end and a dust removal pipeline end. The branch pipe device is disposed between the dust outlet interface end and the dust removal pipeline end. The branch pipe device includes: a container body, the container body is provided with a first connection end, a second connection end, and a third connection end. The first connection end is communicated with the dust outlet interface end, the second connection end is communicated with the dust removal pipeline end, and the third connection end is used for discharging large particle dust. Wherein, the branch pipe device is vertically arranged along the gravity direction, and the second connection end and the third connection end are arranged on opposite sides of the container body. The opening of the second connection end is vertically upward along the gravity direction, and the opening of the third connection end is vertically downward along the gravity direction.

[0005] As a preference, a cylindrical cavity is provided in the container body. The cylindrical cavity communicates with the first connection end, the second connection end, and the third connection end. And a first diameter is provided for the cross-section of the cylindrical cavity, and a second diameter is provided for the cross-section of the first connection end. The first diameter is greater than the second diameter.

[0006] As another preference, a third diameter is provided for the cross-section of the second connection end. The third diameter is smaller than the first diameter.

[0007] Further preferably, a fourth diameter is provided for the cross-section of the third connection end. The fourth diameter is smaller than the first diameter.

[0008] Furthermore, the first connection end includes a plurality of connection openings, and the plurality of connection openings are arranged at intervals around the outer wall of the container body.

[0009] Furthermore, the connection opening includes a first opening and a second opening with different inner diameters, and the first opening and the second opening are evenly arranged at intervals on the outer wall of the container body.

[0010] Furthermore, the third connection end is externally connected to a receiving member for storing the large particle dust.

[0011] Preferably, the distributor further includes a stopper connected to the third connection end. When the stopper abuts against the inner wall of the third connection end, the stopper stops the large particle dust from entering the receiving member, and the receiving member and the stopper cooperate to form a sealed space. When the stopper disengages from the inner wall of the third connection end, the large particle dust can enter the receiving member.

[0012] Preferably, the stopper includes a limiting track and a stop plate body. The limiting track is connected to the third connection end, and the stop plate body movably passes through the limiting track to enter the inner wall channel of the third connection end.

[0013] Preferably, the stopper further includes a locking member that passes through the limiting track and fits with the stop plate body. By applying pressure to the locking member, the relative movement of the stop plate body with respect to the third connection end is prevented.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] When the gas carrying large particle dust enters the column cavity, since the cross-sectional diameter of the column cavity is larger than that of the first connection end, the cross-sectional area of the column cavity is much larger than that of the first connection end. At this time, due to the sudden enlargement of the cross-sectional area, the gas flow rate is greatly reduced. Therefore, the large particle dust carried in the gas sinks into the third connection end under the action of gravity and inertia. At this time, the gas after sedimentation is composed of fine dust and air. The gas composed of fine dust and air can then enter the dust removal pipeline end through the second connection end and is subsequently processed by the dust collector. At the same time, since the second connection end and the third connection end are arranged oppositely in the vertical direction, that is, the air outlet and the dust discharge port are arranged oppositely in the vertical direction, the gas needs to overcome a certain gravity factor and is discharged through the second connection end with an opening provided vertically upward, while the large particle dust only needs to be discharged downward along the gravity direction, thereby further ensuring that the gas discharged along the air outlet has a small dust carrying amount.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0026] As used in the description and claims of this application, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to such process, method, product, or device.

[0027] In a preferred embodiment, referring to Figures 1 to 6 , this application provides a sub-pipe divider 1 for reducing the risk of blockage in the exhaust duct. The exhaust duct includes a dust outlet interface end 2 and a dust removal duct end 3. The sub-pipe divider 1 is disposed between the dust outlet interface end 2 and the dust removal duct end 3. The sub-pipe divider 1 includes: a container body 10, which is provided with a first connection end 11, a second connection end 12, and a third connection end 13. The first connection end 11 communicates with the dust outlet interface end 2, the second connection end 12 communicates with the dust removal duct end 3, and the third connection end 13 is used for discharging large-particle dust. Wherein, the sub-pipe divider 1 is vertically arranged along the gravity direction, and the second connection end 12 and the third connection end 13 are arranged on opposite sides of the container body 10. The opening of the second connection end 12 is vertically upward along the gravity direction, and the opening of the third connection end 13 is vertically downward along the gravity direction.

[0028] Among them, the dust outlet interface end 2 and the dust removal duct end 3 included in the exhaust duct in the related art. The dust outlet interface end 2 is the lead-out end of dust and debris. One end of the dust outlet interface end 2 is connected to the sub-pipe divider 1 in this application document, and the other end is connected to screening equipment, crushing equipment, etc. The dust removal duct end 3 is connected to various dust collectors with different models and powers at one end. Through the suction force generated by the operation of the dust collector, the dust and debris are led out from the dust outlet interface end 2 and sucked towards the dust removal duct end 3. Therefore, the sub-pipe divider 1 in this application document is connected between the dust outlet interface end 2 and the dust removal duct end 3.

[0029] Preferably, a cylindrical cavity is provided in the container body 10. The cylindrical cavity is specifically a powder sedimentation bin. The cylindrical cavity communicates with the first connection end 11, the second connection end 12, and the third connection end 13. The cylindrical cavity includes a first diameter, and the first connection end 11 includes a second diameter d2. The first diameter is greater than the second diameter d2. The wall thickness of the container body 10 is preferably 2 millimeters.

[0030] At the same time, in actual use, the manifold 1 is specifically a large particle separation device. With the gravity direction as the vertical direction, the manifold 1 in the present application document is installed vertically so that the opening of the third connection end 13 is set vertically downward, the third connection end 13 is a discharge end, the first connection end 11 is an air inlet end, the opening is opened in the horizontal direction, the second connection end 12 is an air outlet end, the opening direction is set upward in the vertical direction, the opening extension direction of the first connection end 11 is perpendicular to the opening extension direction of the third connection end 13, that is, the gas carrying large particles of dust enters the column cavity of the container body 10 horizontally from the first connection end 11, and when the gas carrying large particles of dust enters the column cavity, because the cross-sectional diameter of the column cavity is larger than the cross-sectional diameter of the first connection end 11, the cross-sectional area of the column cavity It is much larger than the cross-sectional area of the first connection end 11. At this time, due to the sudden enlargement of the cross-sectional area, the gas flow rate is greatly reduced. Therefore, the large particles of dust carried in the gas sink into the third connection end 13 under the action of gravity and inertia. At this time, the gas after sedimentation is composed of fine dust and air. The gas composed of fine dust and air can then enter the dust removal duct end 3 through the second connection end 12, and be subsequently processed by the dust collector. At the same time, since the second connection end 12 and the third connection end 13 are relatively arranged in the vertical direction, that is, the air outlet and the dust discharge port are relatively arranged in the vertical direction, the gas needs to overcome a certain gravity factor and be discharged along the second connection end 12 with an opening vertically upward, while the large particles of dust only need to be discharged downward along the direction of gravity, thereby further ensuring that the gas discharged along the air outlet carries less dust.

[0031] As another preference, the second connecting end 12 includes a third diameter d3, and the third diameter d3 is smaller than the first diameter.

[0032] Further preferably, the third connecting end 13 comprises a fourth diameter d4, and the fourth diameter d4 is smaller than the first diameter.

[0033] Further preferably, a first transition tube 121 is provided between the container body 10 and the second connecting end 12, and the first transition tube 121 includes a first end and a second end, the first end of the first transition tube 121 is adapted to the first diameter of the container body 10 and is connected to the container body 10, the second end of the first transition tube 121 is adapted to the third diameter d3 of the second connecting end 12 and is connected to the second connecting end 12, and the inner diameter of the first transition tube 121 gradually decreases from the first end to the second end.

[0034] Further preferably, a second transition pipe 131 is provided between the container body 10 and the third connection end 13. The second transition pipe 131 includes a first end and a second end. The first end of the second transition pipe 131 is adapted to the first diameter of the container body 10 and is in communication with the container body 10. The second end of the second transition pipe 131 is adapted to the fourth diameter d4 of the third connection end 13 and is in communication with the third connection end 13. The inner diameter of the second transition pipe 131 gradually decreases from the first end to the second end.

[0035] Among them, the first transition pipe 121 plays a role in contracting and aggregating the gas, so that the flow rate of the gas decreased after passing through the column cavity increases when passing through the first transition pipe 121 to the second connection end 12. The same is true for the second transition pipe 131, and the second transition pipe 131 can play a certain role in aggregating and guiding large-particle dust debris, facilitating the entry of large-particle dust into the third link end through the second transition pipe 131, and thus discharging.

[0036] Further, the first connection end 11 includes a plurality of connection openings 20, and the plurality of connection openings 20 are arranged at intervals around the outer wall of the container body 10.

[0037] Further, the connection opening 20 includes a first opening 21 and a second opening 22 with different inner diameters, and the first opening 21 and the second opening 22 are arranged at equal intervals on the outer wall of the container body 10.

[0038] Specifically, since the first connection end 11 is composed of a plurality of connection openings 20, and the connection openings 20 can be further divided into a first opening 21 and a second opening 22, the second diameter d2 of the first connection end 11 is respectively composed of the fifth diameter d5 of the first opening 21 and the sixth diameter d6 of the second opening 22. Therefore, in a specific embodiment, a plurality of first openings 21 are provided, and a plurality of second openings 22 are also provided. The fifth diameter d5 of the first opening 21 is preferably 75 mm, and the sixth diameter d6 of the second opening 22 is preferably 114 mm. Figures 1 to 3 For example, four first openings 21 are preferably provided, and five second openings 22 are preferably provided. The arrangement of the plurality of first openings 21 and second openings 22 can facilitate the adaptability of the manifold 1 in this application document to various different specifications of the dust outlet interface end 2, so as to expand the usage range of the manifold 1. At the same time, Figure 1 Since the number of the first openings 21 and the second openings 22 of the manifold 1 in [[ ]] is relatively large, in order to facilitate connection, the first openings 21 and the second openings 22 are arranged staggered up and down to reserve sufficient connection space.

[0039] Further, in a specific embodiment, the first diameter is preferably 450 mm, the third diameter d3 is preferably 300 mm, and the fourth diameter d4 is preferably 219 mm.

[0040] Among them, Figures 5 to 6 a manifold 1 with only three second openings 22 and two first openings 21 is given. The fifth diameter d5 of the first opening 21 is also preferably 75 mm, and the sixth diameter d6 of the sixth opening is also preferably 114 mm. Since the number of the first openings 21 and the second openings 22 is small, the first openings 21 and the second openings 22 are only evenly spaced on the outer wall of the container body 10.

[0041] Furthermore, the third connection end 13 is externally connected to a receiving member 30 for storing large-particle dust.

[0042] Preferably, the manifold 1 further includes: a stop member 40 connected to the third connection end 13. When the stop member 40 abuts against the inner wall of the third connection end 13, the stop member 40 stops large-particle dust from entering the receiving member 30, and the receiving member 30 and the stop member 40 cooperate to form a sealed space. When the stop member 40 disengages from the inner wall of the third connection end 13, the large-particle dust can enter the receiving member 30.

[0043] Preferably, the stop member 40 includes: a limiting track 42 and a stop plate body 41. The limiting track 42 is connected to the third connection end 13, and the stop plate body 41 movably passes through the limiting track 42 to enter the inner wall channel of the third connection end 13.

[0044] The bottom of the third connection end 13 is equipped with a stop member 40, which is specifically a kind of slide gate valve. The stop plate body 41 is specifically a kind of flat plate structure. A hose can be externally connected to the third connection end 13 and connected to a sealed receiving member 30. The receiving member 30 is preferably a kind of bucket or bag. When collecting large-particle dust, the stop plate body 41 is pulled out along the limiting track 42 to make the slide gate valve in an open state. The large-particle dust and silicon material fall into the lower sealed bucket or bag through the opened third connection end 13. When the receiving member 30 such as the bucket or bag is full, the stop plate body 41 is pushed along the limiting track 42 to close the slide gate valve. Thus, the sealed bucket or bag can be replaced without stopping the dust collector and other equipment and without affecting the dust removal work, so as to ensure continuous production in the workshop.

[0045] Preferably, the stop member 40 further includes: a locking member 43. The locking member 43 passes through the limiting track 42 and fits with the stop plate body 41. By applying pressure to the locking member 43, the movement of the stop plate body 41 relative to the third connection end 13 is blocked.

[0046] The locking member 43 is specifically a kind of screw-nut matching structure. By rotating the screw relative to the nut, pressure is applied to the stop plate body 41. When the screw rotates to a certain extent, the pressure applied by the screw to the stop plate body 41 is large enough to effectively block the movement of the stop plate body 41 relative to the limiting track 42, and the adjustment method is simple and convenient.

Those skilled in the art should understand that the present application is not limited by the above embodiments.
