Description

Technical Field

[0001] The utility model relates to the technical field of ore particle diameter measurement, in particular to a device that uses sound waves to measure particle diameters. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals, and the classification of ore particle size usually follows international standards, which classify soil particles of different sizes into different levels according to their effective diameters, so they need to be classified during processing.

[0003] After searching, the patent announcement number CN220399278U discloses a device for measuring the grade of ore using near infrared, including a frame body, the outer wall of the frame body is fixedly connected to a push handle, the upper surface of the frame body is fixedly connected to a rotating seat, and the inner wall of the rotating seat is fixedly connected to a driving frame through a bearing. The utility model can effectively measure the ore in the mine, without the need for manual measurement by the surveyor, can prevent the occurrence of safety hazards, and avoid affecting the health of the surveyor. The angle of the measuring instrument can be adjusted according to the size or position of the ore, so that the surveyor can conveniently measure the ore, can collect the qualified ore, and can also screen out the residue of the ore during shipment, avoiding waste of resources, and improving the measurement efficiency and practicality of the equipment.

[0004] The CN220399278U in the prior art can collect qualified ores when in use, and can also screen out the residues of the ore during shipping, so as to avoid waste of resources and improve the measurement efficiency and practicality of the equipment. However, when the ore is actually received for measurement, the ore falls and touches each other, which easily generates dust and affects the measurement environment. In addition, the ore is mostly discharged through a hopper, and the position of the material is not consistent during discharge, so it needs to be improved. Utility Model Content

[0022] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0023] 1. The utility model sets a bearing base. When personnel measure the particle size of the ore, the personnel install a universal wheel through the bottom end surface of the bearing base, so that the personnel hold the handle to push the bearing base to move the bearing base to the position where it needs to be used.

According to the rotation direction of the screw rod, the guide block can be driven up and down to drive the receiving hopper to approach the unloading position to receive the ore. When receiving, when the ore is discharged through the discharge pipe, the ultrasonic particle size analyzer generates and receives the ultrasonic wave to display and measure the ore particle size through the display screen on the control panel, so that the ore can be measured and adjusted according to the actual receiving position.

[0025] 3. The utility model sets up a box body. When personnel receive the ore particle size, in order to avoid the impact of dust generated by the collision of the ore materials on the surrounding environment, the personnel can turn on the exhaust fan to extract the gas in the box body. During the extraction, the end of the connecting pipe away from the gas collecting hood is embedded and fixed in the box body, so that the gas in the box body can be extracted through the connecting pipe. The gas collecting hood extracts the dust gas generated by the received ore, and the dust gas enters the box body and is filtered by the filter bag installed in conjunction with the filter, thereby meeting the requirements of material receiving and measurement and avoiding the impact of dust gas on the measurement environment.
