[0028] Please see Figure 1 and Figure 2This application provides a dust removal device 10 for a separator, used to remove dust during the use of the separator, thereby reducing pollution to the on-site environment and ensuring the safety of operators. The separator includes a feed hopper and two receiving troughs, with the two receiving troughs located below the feed hopper. The feed hopper has an inlet and an outlet, with the inlet located at the top and the outlet at the bottom. The inlet is used to evenly pour in the material to be sampled. After flowing out from the outlet, the material enters the sampling grid, ultimately distributing the material evenly into the two receiving troughs. The structure and working principle of the separator are existing technologies and will not be described in detail here.
[0029] In this embodiment, the bi-divider dust removal device 10 includes a main body 100, a fixing member 200, and a dust removal pipe 300. The main body 100 has a dust removal chamber 111 and an opening 121 and a material inlet 112 communicating with the dust removal chamber 111. The dust removal chamber 111 is used to install the bi-divider. The material inlet 112 is located on the top of the main body 100 and is correspondingly arranged with the feed inlet. The fixing member 200 is located on the main body 100 and is used to fix the feed hopper. The dust removal pipe 300 is located on the main body 100, communicates with the dust removal chamber 111, and is used to connect to dust removal equipment.
[0030] The main body 100 is the basic component of the two-part dust collector 10, used to provide installation and protection for at least other components of the two-part dust collector 10. The main body 100 has a dust collection chamber 111, in which the two-part dust collector can be placed. The main body 100 has a dust collection chamber 111 and a material inlet 112 communicating with the dust collection chamber 111. The material inlet 112 is located at the top of the main body 100. When the two-part dust collector is placed in the dust collection chamber 111, the material inlet 112 is correspondingly set with the feed inlet, so that the material can enter the feed inlet through the material inlet 112. The fixing member 200 can fix the feed hopper to prevent the feed hopper from vibrating when sorting materials, so that the material inlet 112 and the feed inlet are kept in corresponding positions, minimizing material spillage or dust leakage.
[0031] The dust collection duct 300 is used to connect to the dust collection equipment, which is a negative pressure suction filtration system that captures dust through negative pressure suction. Any dust collection equipment provided by the factory can be used, and will not be elaborated further here. The main body 100 has an opening 121 that communicates with the dust collection chamber 111. The opening 121 serves as an air inlet channel, forming a complete airflow path with the dust collection duct 300 to prevent airflow stagnation within the dust collection chamber 111, thereby improving the dust collection effect.
[0032] This application provides a dust removal device 10 for a separator. During the use of the separator, the separator is placed inside the main body 100, and the feed hopper of the separator is fixed by the fixing member 200. The feed inlet and the feed outlet 112 of the separator are correspondingly set. In this way, the material can enter the feed inlet through the feed outlet 112. The dust removal pipe 300 is connected to the dust removal equipment, so that the dust removal equipment can collect the dust raised during the use of the separator, reduce the pollution to the on-site environment, and ensure the safety of the operators.
[0033] In some embodiments, the dust removal device further includes a support plate 400 disposed within the dust removal chamber 111. The support plate 400 supports the feed hopper and is positioned between two receiving troughs. The two receiving troughs are placed on the bottom surface of the dust removal chamber 111, and the support plate 400 provides support to the feed hopper so that the support plate 400 is positioned above the two receiving troughs.
[0034] In some embodiments, the main body 100 includes a housing 110 and a door 120. The material inlet 112, the fastener 200 and the dust removal pipe 300 are all disposed on the housing 110. One side of the housing 110 is open. The door 120 is rotatably connected to the housing 110 and covers at least part of the open.
[0035] The door 120 is connected to the outer casing 110 via hinges. The door 120 can be rotated relative to the outer casing 110 to open and close the opening. Of course, when the door 120 is in the closed state, the door 120 covers at least part of the opening; that is, the door 120 can cover the entire opening or only a part of the opening. When the separator needs to be placed into the dust collection chamber 111, the door 120 is opened. When the separator is placed and material screening begins, the door 120 is closed, so that external air can only enter through the opening 121, avoiding the dispersion of the suction negative pressure and improving dust collection efficiency.
[0036] For example, the door 120 may only cover the open portion, while the remaining portion of the open is configured as opening 121. Specifically, the door 120 covers the upper part of the open, and the lower part of the open is configured as opening 121. It is also understood that the two receiving troughs are placed on the bottom surface of the dust removal chamber 111, that is, the two receiving troughs are located at the lower part of the dust removal chamber 111, so the two receiving troughs can be set exactly to correspond to opening 121.
[0037] In some embodiments, the fastener 200 includes two fastening portions 210, which are telescopically disposed on the housing 110. The two fastening portions 210 are located on both sides of the feed hopper and can abut against the feed hopper.
[0038] After the feed hopper is placed in the dust removal chamber 111, the two fixing parts 210 extend to abut against both sides of the feed hopper, fixing the feed inlet to prevent vibration during material sorting. This ensures that the discharge port 112 is aligned with the feed inlet, minimizing material spillage or dust leakage. After use, the two fixing parts 200 retract to separate from the separator, allowing it to be removed.
[0039] Specifically, the fixing part 210 is threadedly connected to the outer casing 110. That is, the fixing part 210 can be a screw, and both sides of the outer casing 110 are provided with screw holes 114. The fixing part 210 passes through the screw holes 114 and is threadedly connected to them. Under the transmission action of the thread, the extension and retraction of the fixing part 210 can be realized. Furthermore, since the thread transmission distance between the fixing part 210 and the screw hole 114 is controllable, that is, the extension and retraction length of the fixing part 210 is controllable, the two fixing parts 210 can also be used to fix feed inlets of different sizes, improving the versatility of the two-part dust collector 10.
[0040] In some embodiments, the main body 100 may be generally cuboid, and the main body 100 has two sides that are arranged opposite to each other along its length direction and two sides that are arranged opposite to each other along its width direction. The dust removal pipe 300 and the door 120 may be arranged opposite to each other, and the dust removal pipe 300 and the door 120 are arranged opposite to each other along the length direction of the main body 100. The two fixing parts 210 are arranged opposite to each other along the width direction of the main body 100.
[0041] In some embodiments, the top of the outer casing 110 is provided with two opposing guide ramps 113, and the feed inlet 112 is disposed between the two guide ramps 113. The two guide ramps 113 are arranged symmetrically, with a larger distance between their upper ends and gradually converging downwards, resembling an inverted figure eight. The lower ends of the two guide ramps 113 are directly connected to the edge of the feed inlet 112. When the material to be screened slides down the guide ramps 113, the component of gravity is decomposed, and the vertical falling speed is reduced, thereby slowing down the falling speed of the material to reduce dust. Furthermore, the double ramps concentrate the material to the feed inlet 112, which can reduce the dust generated by the material dispersing and impacting the sidewalls.
[0042] Specifically, the inclination angle of the guide ramp 113 is 45° to 60°.
[0043] This application provides a dust removal device 10 for a separator. During the use of the separator, the separator is placed inside the main body 100, and the feed hopper of the separator is fixed by the fixing member 200. The feed inlet and the feed outlet 112 of the separator are correspondingly set. In this way, the material can enter the feed inlet through the feed outlet 112. The dust removal pipe 300 is connected to the dust removal equipment, so that the dust removal equipment can collect the dust raised during the use of the separator, reduce the pollution to the on-site environment, and ensure the safety of the operators.
[0044] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
