DETAILED DESCRIPTION

[0023] The utility model provides a dust removal structure. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0024] See also Figure 1-Figure 3 The utility model provides a dust removal structure, including a supporting frame 1, a cover body 2 arranged outside the supporting frame 1, a dust suction duct 3 connected to the inside of the cover body 2, a dust suction mechanism (not shown in the figure) connected to the dust suction duct 3, and a feeding cylinder 4 arranged inside the cover body 2; the feeding cylinder 4 is provided with a feeding hood 41, the feeding hood 41 is provided with a feeding port 42, and the feeding port 42 is provided with a plurality of first shielding soft curtains 43, and the first shielding soft curtains 43 are used to shield the feeding port 42; the dust suction mechanism is used to suck away the dust flying into the inner cavity of the cover body 2 through the dust suction duct 3.

[0025] When feeding, the operator moves the material to be fed to the inside of the cover body 2, opens any one or more of the first shielding soft curtains 43, and then feeds the material into the feeding cover 41 one by one. Since the first shielding soft curtains 43 are soft, the dust outlet can be minimized to the greatest extent. The material enters the feeding cylinder 4 through the feeding port 42. Since the first shielding soft curtain 43 is provided, the lateral diffusion of dust can be reduced. Even a small amount of dust that diffuses to the outside of the feeding cover 41 can be quickly sucked away by the dust collection mechanism. Specifically, the cover body 2 is a soft film, so the cover body 2 needs to be propped up by the support frame 1. The dust collection mechanism is a conventional negative pressure vacuum cleaner, which is not described in detail here.

[0026] See also Figure 2 and Figure 3 In some embodiments, the feeding port 42 is located on one side of the feeding cover 41, and the bottom of the feeding cover 41 is provided with a material guiding slope. The inclined material guiding slope can guide the dropped materials to fall smoothly into the feeding cylinder 4, reducing the impact force of the materials when they fall and the dust generated thereby, and the upwardly flying materials can also be captured by the feeding cover 41, and fall freely to the material guiding slope again, and continue to be put into the feeding cylinder 4 under the guidance of the material guiding slope.

[0027] See also Figure 3 In some embodiments, the plurality of first soft shielding curtains 43 cover the feeding port 42, and the length of the plurality of first soft shielding curtains 43 is greater than the height of the feeding port 42. Specifically, the upper portion of the plurality of first soft shielding curtains 43 is fixed to the side wall of the feeding cover 41, so that the plurality of first soft shielding curtains 43 are located above the feeding port 42. By limiting the length of the plurality of first soft shielding curtains 43, it is ensured that the feeding port 42 can be fully covered, thereby further reducing the spillage of dust.

[0028] See also Figure 1 and Figure 2 In some embodiments, an entrance 21 for people to enter is opened in front of the cover body 2, and a laterally extending upper slide rail 11 and a lower slide rail 12 are provided on the support frame 1. A second shielding soft curtain 22 is slidably provided between the upper slide rail 11 and the lower slide rail 12; the second shielding soft curtain 22 is used to shield the entrance 21. Pull open the second shielding soft curtain 22 and open the entrance 21, so that the operator can move the material to one side of the feeding cylinder 4. Before feeding, pull the second shielding soft curtain 22 and close the entrance 21, so that the interior of the cover body 2 is in a relatively closed space, which is conducive to the operation of the dust collection mechanism. The upper slide rail 11 and the lower slide rail 12 are provided to fix the second shielding soft curtain 22 with a relatively soft texture to prevent it from shifting due to touch or wind.

[0029] See also Figure 2 and Figure 4 In some embodiments, a regulating valve 5 is provided on the dust suction pipe 3, and a turbidity sensor 23 is provided inside the cover body 2. The turbidity sensor 23 and the regulating valve 5 are electrically connected to the controller respectively; the turbidity sensor 23 is used to obtain the turbidity inside the cover body 2, and the controller is used to control the opening degree of the regulating valve 5. The turbidity sensor 23 is used to monitor in real time and feedback is given to the controller, and the opening degree of the regulating valve 5 is adjusted by the controller. When the amount of dust inside the cover body 2 is large, the opening degree of the regulating valve 5 is large; otherwise, the opening degree of the regulating valve 5 is small. The above-mentioned setting is used to change the amount of air entering the regulating valve 5. Of course, the amount of air entering the dust suction pipe 3 can also be changed by changing the suction amount of the dust suction mechanism.

[0030] See also Figure 5In some embodiments, the regulating valve 5 includes a valve body 51 with a hollow interior, pipe joints 52 respectively arranged at the upper and lower parts of the valve body 51, a plug plate 53 inserted on the valve body 51, and a driving member 54 for driving the plug plate 53 to move horizontally. Specifically, when the opening degree of the regulating valve 5 needs to be increased, the driving member 54 drives the plug plate 53 to move outward, so that the distance between the plug plate 53 and the inner cavity side wall of the valve body 51 becomes larger; conversely, the driving member 54 drives the plug plate 53 to move inward, so that the distance between the plug plate 53 and the inner cavity side wall of the valve body 51 becomes smaller. The pipe joint 52 is used to connect with the dust collection pipe 3 through a flange.

[0031] See also Figure 5 In some embodiments, a slot 511 is provided inside the valve body 51, the notch of the slot 511 is connected to the outside, the plug plate 53 is provided in the slot 511, and the plug plate 53 protrudes from the slot 511; the protruding portion of the plug plate 53 is connected to the driving member 54. The slot 511 is provided to limit the trajectory of the lateral movement of the plug plate 53 to prevent the plug plate 53 from vibrating up and down due to wind resistance. The size of the plug plate 53 is limited to be larger than the size of the cross section of the valve body 51, so as to ensure the sealing of the outside of the valve body 51 and prevent dust from overflowing from the position of the slot 511 to the outside of the valve body 51.

[0032] See also Figure 5 In some embodiments, a mounting seat 55 is provided on the outer wall of the valve body 51, the driving member 54 is a cylinder, the cylinder body of the cylinder is fixed on the mounting seat 55, and the output end of the cylinder is fixedly connected to the protruding portion of the plug plate 53 through a connecting seat 56. The mounting seat 55 is provided to provide a mounting position for the cylinder, and the connecting seat 56 is used to realize a stable connection between the cylinder and the plug plate 53.

[0033] See also Figure 4 In some embodiments, the outer end of the dust suction pipe 3 is also connected to the dust collecting mechanism 6. Specifically, the material after entering the dust suction pipe 3 can be recovered by the dust collecting mechanism 6, and the recovered material can be re-fed to avoid waste.

[0034] To sum up, the utility model sets a feeding hood 41 and a first shielding soft curtain 43 in the feeding cylinder 4 to shield the feeding port 42, thereby reducing the escape of dust when the material is fed into the feeding cylinder 4; the set hood body 2, dust suction pipe 3 and dust suction mechanism are used to promptly absorb the dust flying to the outside of the feeding hood 41.
