Embodiment 1

[0088] Such as Figure 1-2As shown, a material particle size on-line detector includes a feed hopper 1, a housing 2, a gas discharge pipe 3, a discharge collection hopper 4, a camera 5 and a retrieving device 12. The feeding funnel 1 is arranged on the left side of the top of the housing 2 , and the feeding funnel 1 communicates with the upper part of the housing 2 . The gas discharge pipe 3 is arranged on the right side of the top of the housing 2 , and the gas discharge pipe 3 communicates with the upper part of the housing 2 . The material retrieving device 12 is arranged above the casing 2 and the recovery end position of the material retrieving platform 1201 of the material retrieving device 12 is located above the feeding funnel 1 . The discharge collection bucket 4 is arranged at the lower part of the housing 2 and the discharge collection bucket communicates with the bottom of the housing 2 . Wherein the housing 2 is provided with an air inlet 6 on the left side wall...

Embodiment 2

[0096] Repeat Example 1, just as image 3 As shown, the detector also includes a control system 14 connected to the camera 5 .

Embodiment 3

[0098] Repeat Example 2, except that the air inlet 6 is an air inlet with a perforated plate structure.

Abstract

A material particle size online detector is characterized by comprising a material feeding funnel (1), a shell (2), a gas exhaust pipe (3), a discharged material collecting hopper (4) and a camera (5); the material feeding funnel (1) is arranged on one side (such as the left side) of the top of the shell (2); the material feeding funnel (1) is communicated with the upper part of the shell (2); thegas exhaust pipe (3) is arranged on the other side (such as the right side) of the top of the shell (2) or at the upper part of the side wall of the shell (2); the gas exhaust pipe (3) is communicated with the internal space in the shell (2); the discharged material collecting hopper (4) is arranged at the lower part of the shell (2) and the discharged material collecting hopper (4) is communicated with the bottom of the shell (2), wherein the an air inlet (6) is formed in the side wall, corresponding to one side with the material feeding funnel (1), of the shell (2); and the camera (5) is arranged at the side part of the shell (2). The material particle size online detector provided by the invention has the advantages that real-time online detection can be provided, the theoretical principle is simple, the operation is stable, and the reliability is high.

Description

technical field [0001] The invention relates to a material particle size detection device and method, in particular to an online material particle size detector and a detection method thereof, which belong to the field of raw material preparation in metallurgical sintering and pelletizing industries. Background technique [0002] In the field of metallurgical sintering and pelletizing, improving the air permeability of the material layer of the sintering machine can make the ore material heated more evenly, increase the thickness of the auxiliary material on the sintering machine trolley, and improve the quality and output of the sintering ore. If the material particles are too small, the gap between the materials is too small, which is not conducive to the air flow between the gaps, which will cause uneven heating of the materials, thereby increasing energy consumption; when the material particles are too large, the gap between the materials will increase, and the temperatur...
