DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A fire prevention device for crushing materials of a crusher comprises a body 1, an air inlet hole communicating with the interior is provided on the side of the body 1, an air inlet pipe 2 is fixedly installed in the air inlet hole, a rectangular block 3 is fixedly installed at one end of the air inlet pipe 2, a rectangular groove is provided at the upper end of the rectangular block 3, a connecting hole communicating with the rectangular groove is provided on the side of the rectangular block 3, and a connecting pipe 4 is fixedly installed in the connecting hole;

[0023] A fan 5 is fixedly installed on the body 1 through a mounting seat, the output end of the fan 5 is connected to the connecting pipe 4, a first absorbent cotton 6 is inserted in the rectangular groove, a cover plate 15 is fixedly installed on the upper end of the first absorbent cotton 6, a water cavity is opened inside the rectangular block 3, a plug hole connected to the water cavity is opened on the bottom wall of the rectangular groove, a second absorbent cotton 7 is fixedly installed on the lower end of the first absorbent cotton 6, one end of the second absorbent cotton 7 is inserted into the water cavity through the plug hole, and the water absorption of the first absorbent cotton 6 is lower than that of the second absorbent cotton 7;

[0024] An L-shaped water injection pipe 8 is fixedly installed on the side of the rectangular block 3, and a water injection hole connected to the water injection pipe 8 is opened on the inner wall of the water cavity. The water injection pipe 8 is made of transparent material;

[0025] Water with a relatively low temperature can be injected into the water cavity through the water injection pipe 8. When the water is injected into the water cavity, it will be sucked onto the second absorbent cotton 7. Since the water absorption of the second absorbent cotton 7 is greater than that of the first absorbent cotton 6, when the first absorbent cotton 6 absorbs water from the second absorbent cotton 7, the water will only be partially absorbed on the first absorbent cotton 6, thereby facilitating the wind to pass through the first absorbent cotton 6.

[0026] When the crusher is in use, the fan 5 is started, and the wind generated by the fan 5 will enter the rectangular groove through the connecting pipe 4 and pass through the first absorbent cotton 6 in the rectangular groove. When the wind passes through the first absorbent cotton 6, the low-temperature water absorbed in the first absorbent cotton 6 will cool the wind, thereby generating cold wind. The generated cold wind then enters the crusher through the air inlet pipe 2, cooling the interior of the machine body 1 to prevent fire and damage.

[0027] A feed pipe 9 connected to the interior is fixedly installed on the side wall of the body 1, and a material box 10 is fixedly connected to the upper end of the feed pipe 9. The material box 10 is filled with dry powder. A sealing component for blocking the feed pipe 9 is provided inside the feed pipe 9. A rectangular hole is opened on the lower surface of the feed pipe 9. The sealing component includes a sealing plate 11 inserted in the rectangular hole, two spring rods 12 symmetrically fixedly installed at the lower end of the sealing plate 11 and a mounting plate 13 fixedly installed at the lower ends of the two spring rods 12. The mounting plate 13 is fixedly installed on the body 1. A fireproof pad is fixedly installed on the side of the sealing plate 11 close to the body 1, and a sealing pad is fixedly installed on the side away from the body 1. The fireproof pad can prevent the sealing plate 11 from burning when a fire occurs inside the crusher. The sealing pad can reduce the gap between the sealing plate 11 and the rectangular hole, so that the dry powder seeps out from the rectangular hole.

[0028] The sealing plate 11 is inserted into the feed pipe 9, thereby blocking the feed pipe 9. At this time, the dry powder in the material box 10 cannot enter the body 1. When the crusher catches fire, the staff can pull the sealing plate 11 to move vertically downward, the spring rod 12 is compressed, and the feed pipe 9 will be opened. At this time, the dry powder will enter the body 1 from the material box 10, and the dry powder will quickly extinguish the fire inside the body 1, effectively preventing the fire from spreading.

[0029] A flame detector 14 is fixedly installed on the body 1, and an alarm is installed on the flame detector 14. The flame detector 14 and the alarm are electrically connected. The flame detector 14 is a prior art and can detect whether there is a fire inside the crusher. When a fire occurs, the alarm will sound an alarm in the first time, thereby being able to remind the staff in the first time.

[0030] In the utility model, when the crusher is in use, the fan 5 is started, and the wind generated by the fan 5 enters the rectangular groove through the connecting pipe 4 and passes through the first absorbent cotton 6 in the rectangular groove. When the wind passes through the first absorbent cotton 6, the low-temperature water absorbed in the first absorbent cotton 6 will cool the wind, thereby generating cold wind. The generated cold wind then enters the crusher through the air inlet pipe 2, cools the inside of the machine body 1, and prevents fire from causing losses.

[0031] In general, in response to the technical problem: when the crusher is crushing solid materials, the materials are very easy to catch fire, which may cause a fire and cause huge losses; the technical solution is adopted: through the cooperation of the fan 5, the connecting pipe 4, the rectangular block 3, the first absorbent cotton 6, the second absorbent cotton 7 and the air inlet pipe 2, a relatively low-temperature gas is blown into the inside of the body 1; because the implementation process of the technical solution is: when the crusher is in use, the fan 5 is started, and the wind generated by the fan 5 will enter the rectangular groove through the connecting pipe 4 and pass through the first absorbent cotton 6 in the rectangular groove. When the wind passes through the first absorbent cotton 6, the low-temperature water absorbed in the first absorbent cotton 6 will cool the wind, thereby generating cold wind, and the generated cold wind enters the crusher through the air inlet pipe 2, which has a cooling effect on the inside of the body 1; so the technical problem can definitely be solved, and the technical effect achieved is: preventing fires and causing losses.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
