DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. 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 utility model.

[0027] In order to solve the technical problem of poor dust removal effect, the utility model provides a dust removal device, which can improve the dust removal effect of fertilizers.

[0028] It should be noted that the dust removal device described in the utility model is used for but not limited to fertilizer dust removal, etc. For the convenience of explanation, in the utility model, only a dust removal device applied to fertilizer dust removal is used as an example for explanation, and the principle of a dust removal device applied to other types of equipment is essentially the same as the principle applied to fertilizer dust removal, which will not be repeated here.

[0029] See also Figure 1 - Figure 3 , Figure 1 This is a structural schematic diagram of a dust removal device in an embodiment of the utility model, a dust removal device includes a tank body 1, a feed pipe 2, an air supply fan 3 and a blower 4, a feed port 11 is provided on the side wall of the tank body 1 near the top, a dust exhaust port 12 is provided on the top of the tank body 1, the feed pipe 2 is connected to the feed port 11, an air supply port 21 is provided on the side wall of the feed pipe 2, the air supply fan 3 is connected to the air supply port 21, and the blower 4 is connected to the dust exhaust port 12.

[0030] In this embodiment, on the one hand, the feed pipe 2 is connected to the air supply fan 3, and the air supply fan 3 continuously transmits wind to the feed pipe 2, so that the wind generated by the air supply fan 3 can separate the dust and fertilizer; on the second hand, the dust exhaust port 12 is connected to the blower 4, and the blower 4 continuously extracts the air in the tank body, so that the dust exhaust port 12 is in a negative pressure state, so that all the dust can be discharged from the tank body 1 upward from the dust exhaust port 12, effectively avoiding that part of the dust continues to fall with the material due to lack of force, and effectively improving the dust removal effect.

[0031] First, the fertilizer enters the tank body 1 along the feed pipe 2 due to its own gravity, and the wind force generated by the air supply fan 3 at the connection between the feed pipe 2 and the tank body 1 makes the fertilizer and the dust enter the tank body 1 in a separated state; second, the blower 4 continuously draws the air in the tank body 1 outward, so that the dust outlet 12 is in a negative pressure state, and the dust will move upward in the direction of the negative pressure state and be discharged from the dust outlet 12, and the fertilizer will continue to fall due to its own gravity, so that the fertilizer dust removal effect can be achieved.

[0032] In one embodiment, see Figure 1A first connecting pipe 41 is connected between the blower 4 and the dust outlet 12. In this embodiment, the first connecting pipe 41 is a flexible pipe, which effectively avoids the problem that the vibration generated by the blower 4 is transmitted to the tank body 1 and causes the connection between the first connecting pipe 41 and the dust outlet 12 to become loose, and also avoids the problem that the tank body 1 is vibrated and the service life is reduced.

[0033] In one embodiment, see Figure 1 The end of the blower 4 away from the first connecting pipe 41 is connected to a dust box 5. In this embodiment, the dust box 5 is used to temporarily store the dust separated from the fertilizer to prevent the dust from being directly discharged into the outside air and polluting the environment.

[0034] In one embodiment, see Figure 3 A second connecting pipe 42 is connected between the blower 4 and the dust box 5. In this embodiment, the second connecting pipe 42 also adopts a flexible pipe, which effectively prevents the vibration generated by the blower 4 from being transmitted to the dust box 5, thereby reducing the service life of the dust box 5.

[0035] In one embodiment, see Figure 3 , the bottom of the dust box 5 is in an inclined state. In this embodiment, the bottom of the dust box 5 is in an inclined state, which is convenient for the staff to clean the dust box 5, and the dust can be discharged along the inclined surface of the bottom.

[0036] In one embodiment, see Figure 3 The dust box 5 is provided with a slag discharge port 51. In this embodiment, the slag discharge port 51 is used to facilitate cleaning of the dust box 5.

[0037] Furthermore, the slag discharge port 51 is provided with a door, which is opened when cleaning is required and closed when cleaning is not required.

[0038] In one embodiment, see Figure 3 The dust outlet 12 is fixedly connected to an extension tube 121 in the direction toward the inside of the tank body 1, and the end of the extension tube 121 away from the dust outlet 12 is funnel-shaped. In this embodiment, the end of the extension tube 121 away from the dust outlet 12 is funnel-shaped, which effectively increases the air intake, so that more dust is sucked into the extension tube 121.

[0039] In one embodiment, see Figure 2 A third connecting pipe 31 is connected between the air supply fan 3 and the air supply port 21. In this embodiment, the third connecting pipe 31 also adopts a flexible pipe, which effectively alleviates the influence of the vibration generated by the air supply fan 3 on the feed pipe 2.

[0040] In one embodiment, see Figure 1The outer wall of the tank body 1 is fixedly connected with a support frame 13. In this embodiment, the number of the support frames 13 is at least three, one end of the support frame 13 is fixedly connected to the outer wall of the tank body 1, and the other end of the support frame 13 is fixedly connected to the ground by bolts.

[0041] In one embodiment, see Figure 3 The bottom of the tank body 1 is provided with a discharge port 14. In this embodiment, the bottom of the tank body 1 adopts an inverted cone structure, and its cross-sectional diameter gradually decreases from top to bottom. The discharge port 14 has the smallest diameter. The discharge port 14 is used to discharge the dust-removed fertilizer from the tank body 1 to a preset position.

[0042] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0043] First, the fertilizer enters the tank body 1 along the feed pipe 2 due to its own gravity, and the wind force generated by the air supply fan 3 at the connection between the feed pipe 2 and the tank body 1 effectively separates the fertilizer and the dust; then, the blower 4 continuously draws the air in the tank body 1 outward, so that the first connecting pipe 41 and the second connecting pipe 42 are both in a negative pressure state, and the dust will move upward in the direction of the negative pressure state, and enter the dust collecting box 5 after passing through the extension pipe 121, the dust exhaust port 12, the first connecting pipe 41, the blower 4 and the second connecting pipe 42 in turn; finally, the fertilizer continues to fall due to its own gravity and is discharged from the discharge port 14, thus completing the dust removal effect of the fertilizer.

[0044] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
