Technical Field

[0001] This utility model relates to the field of dust suppression technology for raw coal crushing, and in particular to a dust suppression device for a raw coal crusher. Background Technology

[0002] A raw coal crusher is a machine used to crush coal ore. It is also commonly used to crush other brittle materials and medium-hard materials with low moisture content.

[0003] In existing technologies, when raw coal is crushed, a lot of dust is emitted from the top of the raw coal crusher's feed hopper. The large amount of dust dispersed in the air is inhaled by the operators, which can cause harm to their health. To address this issue, we have designed a dust suppression device for raw coal crushers. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a dust reduction device for a raw coal crusher.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A dust suppression device for a raw coal crusher includes a crusher body 1. A support frame is fixedly installed at the bottom of the crusher body 1, and multiple locking casters are provided at the bottom of the support frame. A feed hopper 3, which is internally connected to the crusher body 1, is fixedly installed at the top of the crusher body 1. An installation frame 2 is fixedly installed between the crusher body 1 and the feed hopper 3. A baffle frame 5 is fixedly installed at the top of the feed hopper 3. A baffle plate 10 is fixedly installed on the side wall of the baffle frame 5, with the bottom of the baffle plate 10 abutting against the top of a placement frame 6. A top rod 9 is fixedly installed on the side wall of the baffle frame 5. A feeding mechanism is provided on the side wall of the installation frame 2. The feeding mechanism includes an electric push rod 4 fixedly installed on the side wall of the installation frame 2. The extension of the electric push rod 4... A placement frame 6 is fixedly installed at the constricted end. A connecting plate 13 is fixedly installed on the side wall of the placement frame 6. The inner bottom of the placement frame 6 is inclined. The placement frame 6 extends into the baffle frame 5 and is slidably connected to it. A first sliding groove 12 and a second sliding groove 14 are provided on the placement frame 6. A sealing plate 15 is slidably connected in the second sliding groove 14. A plurality of springs 16 are fixedly connected between the side wall of the sealing plate 15 and the inner side wall of the second sliding groove 14. A sliding rod 17 is fixedly installed on the side wall of the sealing plate 15. The sliding rod 17 extends into the first sliding groove 12 and is slidably connected to it. A sliding plate 11 is slidably connected in the first sliding groove 12. The right end of the sliding rod 17 is fixedly connected to the side wall of the sliding plate 11.

[0024] By setting up the baffle frame 5 and the feeding mechanism, when crushing raw coal, it can shield the dust that drifts out of the feed hopper 3 during crushing and discharge it outside the processing workshop, reducing the amount of dust drifting into the air.

[0025] A dust pump 7 is fixedly installed on the top of the baffle frame 5. The input end of the dust pump 7 is fixedly connected to an air inlet pipe 8 that communicates with its interior. The air inlet pipe 8 passes through the top of the baffle frame 5 and is fixedly connected to it. The output end of the dust pump 7 is fixedly connected to an exhaust pipe that communicates with its interior. The exhaust end of the exhaust pipe extends to the outside of the processing workshop.

[0026] By using the dust pump 7, air inlet pipe 8, and exhaust pipe on the baffle frame 5, the dust entering the placement frame 6 can be sucked out and discharged outside the processing workshop, further reducing the dispersion of dust.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] When raw coal needs to be crushed, the operator first starts the crusher body 1 and the dust pump 7. Then, the operator puts the raw coal into the placement frame 6. When the placement frame 6 is full of raw coal, the operator starts the extension of the electric push rod 4. The electric push rod 4 drives the placement frame 6 to gradually enter the baffle frame 5. When the side wall of the sliding plate 11 at the bottom of the placement frame 6 abuts against the end of the top rod 9, the top rod 9 squeezes the sliding plate 11 to slide to the right. The sliding plate 11 drives the sealing plate 15 to slide to the right through the sliding rod 17. The sealing plate 15 is released from the sealing of the placement frame 6. At this time, the top opening of the placement frame 6 is completely inside the baffle frame 5. The raw coal in the placement frame 6 falls through the bottom of the placement frame 6 into the crusher body 1 for crushing. The dust generated during crushing enters the feed hopper 3. Due to the obstruction of the placement frame 6, the dust is removed. Dust cannot be dispersed into the outside air. In addition, when the dust pump 7 is working, it sucks in the dust that has dispersed into the placement frame 6 through the air inlet pipe 8 and discharges it to the outside of the processing workshop through the discharge pipe on the dust pump 7. After the raw coal in the placement frame 6 has completely fallen, the operator controls the electric push rod 4 to retract. The electric push rod 4 drives the placement frame 6 to slide to the right. At this time, the sliding plate 11 gradually disengages from the top rod 9. The sealing plate 15 slides back to its original position under the action of the spring 16 and gradually seals the placement frame 6. Before the placement frame 6 is completely sealed, the baffle 10 always blocks the top opening of the placement frame 6. When the placement frame 6 is completely sealed, the opening on the placement frame 6 disengages from the baffle 10. Then the operator puts the raw coal into the placement frame 6 and repeats the above operation to continue the crushing operation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
