Description

Technical Field

[0001] This utility model relates to the field of ring hammer crushers, specifically to an air volume regulating device applied to ring hammer crushers. Background Technology

[0002] A ring hammer crusher is a device that crushes coal by striking it with ring hammers. It includes a housing, inside which are a rotor assembly and a screen assembly. The main shaft of the rotor assembly is connected to the output shaft of a motor, and the motor drives the rotor assembly to rotate, thus making the ring hammers work.

[0003] Currently, when the ring hammer crusher is working, coal enters from the feed inlet at the top of the box. The air volume generated by the coal flow drop and the air volume generated by the rotation of the rotor assembly cannot be controlled, resulting in uneven coal feeding, large amounts of dust, and pollution of the site environment. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an air volume regulating device for a ring hammer crusher, which can control the air volume generated by the coal flow drop and the air volume generated by the rotation of the rotor assembly, thereby reducing dust and reducing pollution to the on-site environment.

[0005] The purpose of this utility model is achieved as follows: It includes an airflow baffle, a driven shaft is bolted to the left end of the airflow baffle, and a drive shaft is bolted to the right end of the airflow baffle. The driven shaft is rotatably connected to the liner of the ring hammer crusher and the left side wall of the housing. The left end of the driven shaft extends out from the left side wall of the ring hammer crusher housing. An annular left support seat is provided on the outside of the driven shaft extending out from the left side wall of the ring hammer crusher housing. The left support seat is welded to the left side wall of the ring hammer crusher. The left pressure cover is bolted to the left end face of the left support seat. The setting of the left pressure cover and the left support seat can prevent the left end of the driven shaft from being exposed.

[0006] The drive shaft is rotatably connected to the liner and the right side wall of the housing of the ring hammer crusher, and the drive shaft extends from the right side wall of the housing. An annular right support seat is provided on the outside of the drive shaft extending from the right side wall of the ring hammer crusher housing. The right support seat is welded to the right side wall of the ring hammer crusher housing. The right pressure cover is bolted to the right end face of the right support seat. The right pressure cover has a hole for the drive shaft to extend out. The drive shaft extends out from the hole of the right pressure cover. From left to right, the drive shaft extending out from the right pressure cover has a first square section, a circular threaded section, and a second square section. The positioning plate has a square hole that matches the first square section of the drive shaft. The positioning plate fits onto the first square section of the drive shaft through the square hole. A nut is screwed onto the circular threaded section of the drive shaft. The bottom of the wrench has a square hole that matches the second square section of the drive shaft. The square hole of the wrench fits onto the second square section of the drive shaft.

[0007] The right end face of the right pressure cover is provided with several positioning holes, the centers of these positioning holes are on the same circumference, the lower part of the positioning plate has a hole, the positioning pin is set in the hole in the lower part of the positioning plate, the left end of the positioning pin is inserted into the positioning hole of the right pressure cover, and a spring is sleeved on the positioning pin located between the right pressure cover and the positioning plate.

[0008] The airflow baffle is arranged parallel to the main shaft of the rotor assembly of the ring hammer crusher, and the airflow baffle is located above the rotor assembly.

[0009] The advantages of this invention are: during operation, a suitable opening angle can be selected according to actual needs. For example, the lowest positioning hole can be set to 0°, and the other positioning holes from bottom to top can be 45°, 90°, and 135° respectively. If the airflow baffle needs to be rotated 45°, simply move the wrench to align the positioning pin with the positioning hole at 45° and insert the positioning pin into the positioning hole. At this time, the airflow baffle inside the housing will rotate 45°. By rotating the airflow baffle in this device, the airflow generated by the coal flow drop and the airflow generated by the rotation of the rotor assembly can be controlled, thereby reducing dust and lowering the pollution to the on-site environment.
