The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

As shown in fig. 1-6, the utility model discloses an automatic pressure relief explosion-proof pulverizer, which comprises a cup body 200, wherein a pulverizing cavity 2001 is arranged in the cup body 200, a pressure relief opening 2002 is arranged at the top of the cup body 200, and the pressure relief opening 2002 is communicated with the pulverizing cavity 2001. In addition, be provided with automatic relief valve on the relief vent 2002, automatic relief valve includes exhaust cover 31, and exhaust cover 31 is used for covering relief vent 2002, and the bottom of exhaust cover 31 is provided with lift guide pillar 32, and lift guide pillar 32 wears to establish in relief vent 2002. In this way, the exhaust cover 31 moves up and down with respect to the relief port 2002 under the guide of the elevating guide post 32 to open or close the relief port 2002.

Specifically, when the pressure in the grinding chamber 2001 is normal, the pressure release opening 2002 is covered by the exhaust cover 31 under the action of gravity. When the pressure in the grinding chamber 2001 is too high, the air discharging cover 31 is pushed to move upwards along the guide of the lifting guide post 32 under the pushing of the internal air, so that the air discharging cover 31 moves to open the pressure relief opening 2002, and the purpose of pressure relief of the grinding chamber 2001 is achieved. Conversely, when the pressure in the grinding chamber 2001 returns to normal, the exhaust cover 31 moves downward along the guide of the lifting guide post 32 under the action of gravity, so that the exhaust cover 31 moves to close the pressure relief opening 2002.

Therefore, by arranging the automatic pressure release valve, when the pressure in the grinding cavity 2001 is excessive, the air discharge cover 31 is pushed to move upwards along the guide of the lifting guide post 32 under the pushing of the internal air so as to open the pressure release opening 2002; on the contrary, when the pressure in the milling chamber 2001 is recovered to be normal, under the effect of self gravity, the exhaust cover 31 moves downwards along the guide of the lifting guide pillar 32 to close the pressure relief opening 2002, so that the automatic pressure relief and explosion prevention function of the milling machine can be realized, and meanwhile, by adopting the structure, the automatic covering function of the pressure relief opening 2002 after pressure relief can be realized, and the long-term leakage of the pressure relief opening 2002 is avoided, so that the sanitation condition in the milling chamber 2001 is effectively ensured.

The bottom of the lifting guide pillar 32 is provided with a limit base 33, the limit base 33 is located in the grinding chamber 2001, and the size of the limit base 33 is larger than the pressure relief opening 2002, that is, the limit base 33 cannot be directly ejected out of the pressure relief opening 2002, so that under the limit action of the limit base 33, when the pressure in the grinding chamber 2001 is prevented from being too large, the exhaust cover 31 can be directly ejected from the pressure relief opening 2002 to be separated. Further, the limiting base 33 is provided with a vent 331, and when the limiting base 33 is abutted against the pressure relief 2002, the grinding chamber 2001 can be communicated with the outside through the vent 331; that is, when the exhaust cover 31 is pushed to move upward along the guide of the lifting guide post 32 under the pushing of the internal air, so that the limit base 33 abuts against the pressure relief opening 2002 and covers the pressure relief opening 2002, the air in the grinding chamber 2001 can still be discharged outwards through the air vent 331 by the arranged air vent 331, so that the problem that the limit base 33 can completely cover the pressure relief opening 2002 is avoided, and the reliability of pressure relief is effectively ensured. It should be noted that, with such a structure, the whole pressure release channel is not a straight channel, but a pressure release channel similar to a circular arc, so that the purpose of the arrangement is to make the powder grinding chamber 2001 smoothly leak air during pressure release, and the powder in the powder grinding chamber 2001 is not easily taken away, so as to prevent the powder in the powder grinding chamber 2001 from being easily carried to the outside of the pressure release opening 2002 by the air.

Wherein, the ventilation port 331 is provided with at least two and arrange along the circumference of spacing base 33, in this embodiment, the ventilation port 331 is provided with two, so, through increasing the quantity of ventilation port 331, can effectively increase the quantity of pressure release export to promote the pressure release ability.

The lifting guide post 32 gradually increases and changes in size from one end of the limit base 33 toward one end of the exhaust cover 31. In this embodiment, the lifting guide post 32 has an inverted trapezoid shape, so, due to the shape of the lifting guide post 32, the channel in the pressure relief opening 2002 is narrowed, and the purpose of the arrangement is to enable the air to smoothly leak away when the powder grinding chamber 2001 is depressurized, and the powder in the powder grinding chamber 2001 is not easily taken away, so that the powder in the powder grinding chamber 2001 is prevented from being easily taken to the outside of the pressure relief opening 2002 by the air.

Wherein, the top of cup 200 is provided with the platform that sinks, sinks the platform and sinks in the surface of cup 200, and the bottom of sinking platform is provided with pressure release mouth 2002, and is formed with downward sloping drainage inclined plane 4 on the lateral wall of sinking platform. Thus, when air is discharged from the pressure relief port 2002 to enter the sinking platform, the air can be better discharged from the sinking platform to the outside of the cup body 200 under the action of the drainage inclined plane 4.
