Problems solved by technology

The spiral sampling device is more common in the downflow sampler; the sampling volume of this device can be guaranteed, but the structure is relatively complicated
The sampling head and the spiral reamer of this device have no automatic cleaning function, the material will adhere to the surface of the spiral reamer, and the material will fall into the sampling head during non-sampling time; thus it will cause certain pollution to the next samp

Embodiment Construction

[0017] When the material falls in the material channel, the PLC in the control box (9) sends a control signal to the solenoid valve, which controls the solenoid valve to supply air to the cylinder (5). The piston rod of the cylinder (5) is recovered, which drives the connecting mechanism (8) to rotate, and the sampling knife (1) swings into the material channel slowly and at a uniform speed to intercept the material flow. The intercepted material will flow out from the discharge flange (6) through the fixed base (7) along the inclined direction of the sampling knife (1), thus completing the sampling work. After the sampling is finished, the PLC in the control box (9) sends out a control signal to control the solenoid valve to supply air to the cylinder (5), and the piston rod of the cylinder (5) is stretched out, driving the connecting device (8) to rotate, and the sampling knife (1) is slowly recovered , the scraper (10) removes the sticky material on the sampling knife (1) d...

Abstract

The invention relates to a swing type material sampling device with an automatic cleaning function, which can be used for on-line sampling through a material flow intercepting method in industries such as coal, cement, metallurgy and the like, and can ensure that each particle of a sampled material has equal probability to be sampled into a sample. The sampling cutter can be electrically, pneumatically or hydraulically driven to swing at a certain angle, and materials can be sampled online in real time. The device is provided with a double cleaning system of knocking cutter cleaning and mechanical cutter cleaning, and has the advantages of simple structure, safety, stability, high efficiency, high sampling representativeness, convenience in installation, no occupation of the internal space of a material channel and the like.

Description

technical field [0001] The invention relates to an online material sampling device, in particular to a mechanized mobile flow material sampling device. Background technique [0002] In industries such as coal and cement, it is necessary to analyze the properties and quality of materials at each production stage in real time to achieve the purpose of quality control; therefore, every process from sampling, sample preparation to analysis is very important. Nowadays, the sampling process has changed from traditional manual sampling to mechanical automatic sampling, and its efficiency, accuracy, and timeliness have been greatly improved. Existing mechanized sampling can be divided into static and moving flow, and moving flow sampling mainly includes cross-belt sampler and downflow sampler. The spiral sampling device is more common in the downflow sampler; the sampling volume of this device can be guaranteed, but the structure is relatively complicated. The sampling head and th...
