Description
Technical Field
[0001] The utility model relates to the technical field of low-temperature airflow pulverizers, in particular to a micro-fine powder low-temperature airflow pulverizer. Background Art
[0002] Low-temperature airflow pulverizer uses high-speed airflow to finely grind materials. It can be divided into disc-type airflow pulverizer and elliptical airflow pulverizer. After the compressed air is filtered and dried, it is sprayed into the grinding chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the material is repeatedly collided, rubbed, and sheared to be crushed.
[0003] The friction between the material and the crushing chamber will generate static electricity, which may pose a potential threat to the safety of the operator. When the low-temperature airflow mill is in use, the airflow will impact the material guide chamber and the crushing chamber, which may easily cause wear and tear, resulting in a higher frequency of replacement, increasing the cost of use and maintenance. The crushed material is filtered out through a screen, but different materials require different sizes of screens, so the screen often needs to be replaced. When replacing, it is generally necessary to disassemble the discharge pipe first, and then disassemble and assemble the screen, which is more cumbersome and reduces the convenience of replacing the screen of the low-temperature airflow mill.

The airflow pushes the material along the material conduit 205 and the airflow conduit 204 into the crushing tank 1. At the same time, a high-speed airflow is poured into the airflow conduit 204. At the intersection of multiple high-pressure airflows, the material is repeatedly collided, rubbed, and sheared to be crushed, and the rapid transfer of the airflow can quickly take away the heat of the equipment, so that the temperature of the area where the material is located remains stable, avoiding the temperature increase caused by the operation of the machine. Subsequently, the smaller materials after crushing enter the discharge pipe 202 with the airflow, and pass through the screen 207 into the discharge pipe 203, and are discharged through the discharge pipe 203. The larger materials continue to be crushed inside the crushing tank 1 to realize the fine powder low-temperature airflow crushing function of the low-temperature airflow crusher.

Under the action of the wear-resistant inner cylinder 401, the inner wall of the crushing tank 1 can be protected, and it is not easy to wear too quickly due to the friction between the material and the inner wall. At the same time, when the airflow carries the material through the material conduit 205 and enters the feed port 206, due to the direction of movement, The change causes the airflow and the material to impact the bending section. At this time, the airflow can be buffered by the buffer pad 4024, and the impact can be further buffered and unloaded by the elastic column 4021. The elastic sleeve 4023 can prevent the material from entering the elastic sleeve 4023. With the cooperation of the connecting plate 4022 and the screws, the buffer pad 4024 can be conveniently installed inside the feed port 206 to realize the wear-resistant function of the low-temperature airflow pulverizer and reduce the replacement frequency of wear parts, thereby saving the use cost and maintenance cost.
[0035] Static electricity is easily generated when materials are rubbed. At this time, the control row key 102 can be operated to make the control row key 102 control the blower 5012 and the ion generator 502 to generate positive and negative ions under the action of the ion generator 502, and enter the air duct 5013 under the action of the blower 5012, and are discharged through the micropores 5011 to neutralize the static electricity carried by the materials. Since the aperture of the micropores 5011 is much smaller than the aperture of the screen 207, the material can be prevented from entering the air duct 5013 to realize the anti-static function of the low-temperature airflow pulverizer, so that the low-temperature airflow pulverizer is not easy to bring potential threats to the safety of the operator due to static electricity when using it.
[0036] The screen 207 can be replaced by loosening the fastening bolt 3013 to move the fastening bolt 3013 away from the threaded hole 302, and then the adjusting tube 3011 is pushed upward to move the adjusting tube 3011 above the screen 207, so that the screen 207 can be taken out for replacement, and then the replaced screen 207 is placed inside the placement groove 303, and then the adjusting tube 3011 is loosened to slide the adjusting tube 3011 to the bottom of the guide slide groove 3014.
