Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] As attached Figure 1 , 2 As shown in Figures 3 and 4, this embodiment provides a fully negative pressure anti-spray conveyor integrated machine, including a base 1, a conveying box 2 is provided on the top of the base 1, a storage box 3 is connected to the top of the conveying box 2, a feed pipe 4 is connected to the outer wall of the storage box 3, and a gas extraction port 5 is connected to the top of the storage box 3. A slag discharge port 6 is opened on the surface of the storage box 3, and a sealing door 7 is installed inside the slag discharge port 6. The sealing door 7 is installed inside the slag discharge port 6 by a hinge and is used to open and close the sealing door 7.

[0021] A first explosion-proof motor 8 is installed on the top of the conveying box 2. A slurry pump 9 is installed inside the conveying box 2. A bell-shaped cover 10 is installed at the bottom of the first explosion-proof motor 8. The bell-shaped cover 10 is installed on the top of the conveying box 2. The first explosion-proof motor 8 is installed on the top of the bell-shaped cover 10. The output end of the first explosion-proof motor 8 and the slurry pump 9 are connected by a coupling. The bell-shaped cover 10 is located outside the coupling. A guide plate 13 is installed at an incline inside the conveying box 2. The input end of the slurry pump 9 is located inside the conveying box 2. The output end of the slurry pump 9 extends to the outside of the conveying box 2.

[0022] A mesh screen 11 is fixedly installed inside the storage bin 3. A labyrinth plate 12 is installed inside the storage bin 3 between the feed pipe 4 and the gas extraction port 5. The mesh screen 11 is a funnel-shaped structure formed by four screen plates. The slag discharge port 6 is connected to the bottom of the mesh screen 11.

[0023] Specifically, the principle of this embodiment is as follows: First, the material enters the storage box 3 from the feed pipe 4. The labyrinth plate 12 between the feed pipe 4 and the gas extraction port 5 will prevent the material from being drawn away by the gas extraction port 5. The material falling into the mesh screen 11 is screened into particles of different sizes, and the gas mixed in the material will be drawn away by the negative pressure pipe connected to the gas extraction port 5. The large particles are retained inside the mesh screen 11, while the small particles will fall into the conveying box 2. The inclined guide plate 13 is concentrated on one side of the input end of the slurry pump 9.

[0024] The first explosion-proof motor 8 drives the slurry pump 9 through a coupling to extract small particles of material. Large particles are discharged from the slag discharge port 6 under the action of the funnel-shaped mesh screen 11. This completes the integrated operation of screening, slag discharge, conveying and gas emission of material particles of different sizes.

[0025] Example 2

[0026] This embodiment provides a fully negative pressure anti-blowout conveyor integrated machine, based on Embodiment 1, as shown in the attached... Figure 2 , 3 As shown in Figure 5, a rotating rod 14 is rotatably installed inside the storage bin 3. Two striking blocks 15 are fixedly installed on the outside of the rotating rod 14. A second explosion-proof motor 16 is provided at one end of the rotating rod 14. The second explosion-proof motor 16 is fixedly installed on the back of the storage bin 3, and the output end of the second explosion-proof motor 16 is fixedly connected to the rotating rod 14. The rotating rod 14 and the two striking blocks 15 are all close to one side of the mesh screen 11.

[0027] Specifically, in this structure, considering the risk of clogging of the mesh screen 11, the second explosion-proof motor 16 drives the rotating rod 14 to rotate inside the storage box 3, so that the two striking blocks 15 strike the mesh screen 11, causing the mesh screen 11 to vibrate. On the one hand, this accelerates the screening effect of the mesh screen 11 on the material, and on the other hand, it reduces the risk of clogging of the mesh screen 11.
