DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples, but the examples are not intended to limit the present invention.

[0025] like Figure 1-Figure 2 As shown, an embodiment of the present invention is a jaw crusher with a dust removal function, comprising a crushing box 1, a receiving box 2 and a dust reduction box 6. A connecting plate 25 is fixedly provided at the lower end of the outer wall of the crushing box 1, and the connecting plate 25 is fixed above the receiving box 2 through a support frame 26. A feed hopper 3 is provided at the upper end of the crushing box 1, and the feed hopper 3 is connected to the crushing box 1 through a feed pipe 4. A movable jaw plate 7 and a fixed jaw plate 8 are installed in the crushing box 1.

[0026] The crushing box 1 is connected to the receiving box 2 through a discharge barrel 5 , and a screen 14 is installed in the discharge barrel 5 .

[0027] The material receiving box 2 is arranged below the crushing box 1 , and a material receiving trough 15 is placed inside the material receiving box 2 . Inclined material guide plates 16 are fixedly connected to the inner walls of the left and right side panels of the material receiving box 2 .

[0028] A fixing frame 9 is installed at the right end of the outer wall of the crushing box 1, and a cylinder 10 is installed on the fixing frame 9. The output end of the cylinder 10 is fixedly connected to the push plate 11. A slide 13 is installed in the fixing frame 9. The push plate 11 is connected to the slide 13 for left and right sliding. A baffle 12 is fixedly installed at the left end of the push plate 11. The upper end surface of the baffle 12 is always in contact with the top surface of the inner cavity of the crushing box 1. An opening is opened on the baffle 12. When the push plate 11 is located at the far left, the opening 7 on the baffle 12 faces the feed pipe 4. When the push plate 11 is located at the far right, the baffle 12 can close the feed pipe 4.

[0029] A first dust hood 17 is installed at the upper end of the feed hopper 3, and a second dust hood 18 is installed at the upper end of the receiving box 2. The first dust hood 17 is connected to the connecting pipe 22 through a first connecting branch pipe 20, and the second dust hood 18 is connected to the connecting pipe 22 through a second connecting branch pipe 21. The connecting pipe 22 is connected to the air inlet end of the dust reduction box 6. A baffle 19 is installed in the second dust hood 18, a first valve 23 is installed at the first connecting branch pipe 20, and a second valve 24 is installed at the second connecting branch pipe 21.

[0030] Material enters the crushing chamber 1 from the feed hopper 3 through the feed pipe 4. The control cylinder 10 drives the push plate 11 to slide left and right on the slide 13. When the push plate 11 is at the far left, the opening of the baffle 12 faces the feed pipe 4, allowing material to enter normally. When the push plate 11 is at the far right, the baffle 12 closes the feed pipe 4, controlling the feeding.

[0031] Inside the crushing box 1, the movable jaw 7 and the fixed jaw 8 crush the material. The crushed material is screened by the screen 14 in the discharge barrel 5. Qualified material falls into the receiving trough 15 in the receiving box 2. The inclined guide plate 16 in the receiving box 2 guides the material to fall into the receiving trough 15 more smoothly.

[0032] During the crushing and feeding process, dust generated at the feed hopper 3 is collected by the first dust hood 17, and dust generated at the receiving box 2 is collected by the second dust hood 18. The dust collected by the first dust hood 17 enters the connecting pipe 22 through the first connecting branch pipe 20 and the first valve 23. The dust collected by the second dust hood 18 also enters the connecting pipe 22 through the second connecting branch pipe 21 and the second valve 24. Finally, the dust enters the dust reduction box 6 through the connecting pipe 22 for dust reduction treatment.

[0033] The connecting pipe 22 extends into the interior of the dust removal box 6. An air distribution plate 2201 is fixedly mounted at the lower end of the connecting pipe 22. The air distribution plate 2201 has multiple air holes evenly distributed thereon. The dust removal box 6 contains a dust removal liquid. A porous baffle 602 is mounted within the dust removal box 6. The porous baffle 602 is positioned above the dust removal liquid. The connecting pipe 22 passes through the porous baffle 602. An air outlet 601 is formed at the upper end of the dust removal box 6. Dust-laden gas enters the dust removal box 6 through the connecting pipe 22. After being evenly dispersed by the air distribution plate 2201, it enters the dust removal liquid as tiny bubbles. During this process, dust particles in the gas fully come into contact with the dust removal liquid, where they are adsorbed, condensed, and precipitated. The porous baffle 602 not only prevents larger bubbles from rising directly, but also further disperses and refines the gas as it passes through the porous baffle 602, improving the dust removal effect. Furthermore, the porous baffle 602 prevents the dust removal liquid from violently fluctuating or splashing due to the airflow. The gas treated by the dust removal liquid continues to rise and is discharged from the dust reduction box through the gas outlet 601. At this time, the dust content in the discharged gas is greatly reduced, achieving a good dust removal effect.

[0034] Among them, the electrical components appearing in the article are all electrically connected to an external main controller and a power supply, and the main controller can be a conventional known device that plays a control role such as a computer.

[0035] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
