A grinding feed device for high-chromium steel balls

Abstract

This utility model discloses a grinding and feeding device for high-chromium steel balls, including a storage hopper, a feeding measuring hopper installed at the bottom of the storage hopper, a discharge pipe fixedly installed at the bottom of the storage hopper, a solenoid valve installed on the discharge pipe, and a rotating drum rotatably mounted at the bottom of the solenoid valve via a bearing. The grinding equipment to be used is placed below the feeding measuring hopper at the bottom of the storage hopper. The solenoid valve is opened, and the material inside the storage hopper enters the feeding measuring hopper at the bottom of the storage hopper through the discharge pipe. Air is drawn in by a blower in a baghouse dust collector, and dust generated during the material's fall is absorbed by a dust collection hood. The dust enters the baghouse dust collector through a dust collection pipe, achieving dust removal and improving the air quality of the working environment. Simultaneously, the rotating drum is controlled to rotate, and a pusher rod on the drum can push the material entering the feeding measuring hopper to smooth the material and improve feeding accuracy.

Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding feed device for high-chromium steel balls. Background Technology

[0002] High-chromium steel balls are high-strength, wear-resistant steel balls with chromium as the main alloying element. They are mainly used as grinding media in industrial equipment such as ball mills.

[0003] In the patent application "A Feeding Device for Grinding High-Chromium Steel Balls" with authorization announcement number "CN221674473U", when grinding is required, the grinding equipment is first placed directly below the second electric valve. Simultaneously, the scale line corresponding to the material quantity on the outer wall of the second storage tank is located. The outlet of the first electric valve is moved to the same horizontal plane as the appropriate scale line on the outer wall of the second storage tank. The first electric valve is then activated, and the material inside the first storage tank is directly conveyed to the inside of the second storage tank. When the material just fills to the outlet of the first electric valve, the feeding into the second storage tank will stop. At this point, the amount of material inside the second storage tank is the appropriate amount for this grinding equipment, thus achieving the goal of controlling the appropriate amount of material entering the grinding equipment. However, when feeding the material, the material inside the second storage tank is arranged in a cone shape, and the material cannot accurately reach the same horizontal plane as the appropriate scale line on the outer wall of the second storage tank. At the same time, when feeding the material inside the first storage tank, some dust will be generated, affecting the feeding environment. Utility Model Content

The material will be drawn in by the blower in the bag dust collector, and the dust generated when the material falls will be absorbed by the dust collection hood 6. The dust will enter the bag dust collector through the dust collection pipe 7, thus cleaning the dust and improving the air quality of the working environment. At the same time, control the rotating drum 4 to rotate, and the push rod 5 on the rotating drum 4 can push the material entering the feeding measuring hopper to smooth the material and improve the feeding accuracy.

[0026] During the rotation of the cross 10, the pusher plate 14 will rotate synchronously. The pusher plate 14 can push the material located on the inner wall of the storage hopper 1 to prevent the material from accumulating on the inner wall of the storage hopper 1.

The solenoid valve 3 is opened, and the material inside the storage hopper 1 will enter the feeding measuring hopper at the bottom of the storage hopper 1 through the discharge pipe 2. The blower in the bag dust collector will draw air in, and the dust generated when the material falls will be absorbed by the dust collection hood 6. The dust will enter the bag dust collector through the dust collection pipe 7, thereby cleaning the dust and improving the air quality of the working environment. At the same time, the motor 8 is controlled to operate, and the motor 8 will drive the rotating shaft 9 to rotate. The transmission of the first transmission belt 18 to the second pulley 17 and the first pulley 15 will drive the transmission shaft 16 to rotate. At the same time, the transmission of the second transmission belt 21 to the third pulley 19 and the fourth pulley 20 will drive the rotating drum 4 to rotate. The push rod 5 on the rotating drum 4 can push the material entering the feeding measuring hopper to smooth the material and improve the feeding accuracy.

[0031] When the motor 8 drives the rotating shaft 9 to rotate, the cross 10 will rotate. The stirring rod 11 on the cross 10 can stir the material inside the storage hopper 1 to prevent the material from stagnating inside the storage hopper 1. At the same time, the rotation of the cross 10 will drive the pusher plate 14 to rotate.
