[0002] Silica powder is a multi-purpose material, widely used in refractory materials, silicone chemicals, electronics industry and glass and ceramics industry. The mass production of silica powder is to use various crushing equipment to crush silica ore step by step until the silica ore is crushed into silica powder of different particle sizes. After the silica ore is crushed into small pieces of ore, when it needs to be crushed into silica powder, the commonly used equipment is a cone crusher, and its working principle is: a crushing chamber is formed between the rotating movable cone and the fixed cone, and the material is crushed by multiple squeezing and collision of the movable cone and the fixed cone. During the grinding process, the movable cone and the fixed cone wear faster and have a shorter service life. Whether they need to be replaced or not, it is particularly necessary to develop a highly wear-resistant and long-life silica powder crushing equipment. Summary of the invention

[0019] A vertical pipe 7 is provided at the upper end of the feed port 1, and the vertical pipe 7 extends to the top of the cone crushing device. A plurality of high-pressure jet pipes 8 with downward openings are provided at the inner upper end of the vertical pipe 7, and the high-pressure jet pipes 8 are connected to a high-pressure air pump 9. The high-pressure air pump 9 is a prior art and will not be described in detail here. A feed pipe 10 is provided on the side of the vertical pipe 7 below the high-pressure jet pipe 8.

[0020] The ore enters the vertical pipe 7 from the feed pipe 10, and the high-pressure air pump 9 delivers high-pressure air to the high-pressure jet pipe 8. The high-pressure jet pipe 8 is used to accelerate the ore in the vertical pipe 7, thereby increasing the initial velocity of the ore entering the cone crushing device. The ore is initially crushed by impacting the guide block 5 at a high velocity, thereby reducing the wear on the crushing equipment.

[0021] Embodiment 2: A highly wear-resistant and long-life silicon powder crushing device comprises a cone crushing device, wherein a feed port 1 is arranged at the upper end of the cone crushing device, a cone crushing device housing 2 is arranged inside the housing 2, a fixed cone 3 and a moving cone 4 are arranged, a guide block 5 is arranged at the upper end of the moving cone 4, a discharge port 6 is arranged at the lower end of the housing 2, and the guide block 5 is hemispherical.

[0022] A vertical pipe 7 is arranged at the upper end of the feed port 1, and the vertical pipe 7 extends to the top of the cone crushing device. A plurality of high-pressure jet pipes 8 with downward openings are arranged at the inner upper end of the vertical pipe 7, and the high-pressure jet pipe 8 is connected to a high-pressure air pump 9. The high-pressure air pump 9 is a prior art and will not be described in detail here. A feed pipe 10 is arranged on the side of the vertical pipe 7 below the high-pressure jet pipe 8, and the feed pipe 10 extends obliquely, and an angle of 60 degrees is formed between the feed pipe 10 and the vertical pipe 7. A feed spiral blade 11 is arranged coaxially inside the feed pipe 10, and the feed spiral blade 11 is used to control the feed speed of the ore to avoid excessive wear of the crushing equipment due to excessive one-time feeding.

[0023] An exhaust pipe 12 is provided on the outer shell 2 below the fixed cone 3. The exhaust pipe 12 extends vertically and has an upper end open. The exhaust pipe 12 discharges the gas in the outer shell 2 to avoid a reduction in the ore feed rate due to high air pressure in the outer shell 2.

[0024] The specific working process is as follows: start the high-pressure air pump 9 and the cone crushing device, use the feed spiral blade 11 to gradually let the ore enter the vertical pipe 7 from the feed pipe 10, the high-pressure air pump 9 transports the high-pressure air to the high-pressure jet pipe 8, and uses the high-pressure jet pipe 8 to accelerate the ore in the vertical pipe 7, thereby increasing the initial velocity of the ore entering the cone crushing device, and uses the high-speed impact guide block 5 to initially crush the ore, and then uses the cone crushing device to grind the ore, thereby reducing the wear on the crushing equipment.
