Description

Technical Field

[0001] The present invention relates to the technical field of automatic sampling and detection of fly ash from hazardous waste incineration, and in particular to an automatic sampling and detection device for fly ash from hazardous waste incineration. Background Art

[0002] Incineration is currently a relatively common means of treating hazardous industrial waste, but fly ash is produced after incineration. This fly ash is a substance with a high specific surface area. It is not only enriched with a large amount of toxic heavy metals such as mercury, lead and cadmium, but also enriched with a large amount of dioxins. It is a double-hazardous waste with both heavy metal hazard characteristics and environmental persistent organic toxicity, which is also extremely harmful to human health and the ecological environment.

[0003] With the emergence of some artificial stone products, a new type of green building decoration material is made from a mixture of natural stone tailings crushed stone powder and a specific binding material. Because its production process meets energy-saving, emission-reduction, and low-carbon standards, and can absorb large amounts of industrial tailings and waste, it has broad prospects for application and promotion. Therefore, during the production of artificial stone, it is necessary to collect incineration fly ash and mix it with other materials. The mixed incineration fly ash needs to be tested for hazardous substances before being integrated into cement paste to obtain green building decoration materials.

[0004] Its automatic sampling and detection device for hazardous waste incineration fly ash requires that the incineration fly ash be collected and mixed with some building debris for detection during use. However, due to the large volume of some building debris, the incineration fly ash cannot be evenly blended with them, resulting in inaccurate detection. Therefore, it does not meet existing needs. In response to this, we have proposed an automatic sampling and detection device for hazardous waste incineration fly ash. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention starts the air pump to suck the incineration fly ash into the collection box through the air inlet, and then puts some building debris and other materials into the collection box through the feed port. The materials come into contact with the baffle due to their own gravity, and squeeze the spring to deform, so that they slide along the surface of the baffle and fall into the collection box. After all the materials enter the collection box, the force on the spring is released, so that the baffle is reset and the feed port is closed, preventing the stirred dust from floating out of the collection box and affecting the environment.

[0018] 2. The present invention starts the driving motor to drive the driving gear to rotate. The driving gear rotates and meshes with the driven gear to rotate, thereby driving the two rotating rods to rotate. The two rotating rods rotate and respectively drive the first crushing roller and the second crushing roller to rotate, thereby crushing the larger material entering the feed port. The fixed tooth blocks on both sides of the inner wall of the feed port mesh with the first crushing roller and the second crushing roller, thereby preventing the material from falling into the collection box through the gap on the side of the feed port, making the crushing more uniform.

[0019] 3. The present invention allows the crushed material to fall into the interior of the collection box, and then starts the stirring motor to drive the stirring mechanism to operate. The stirring motor drives the transmission shaft to rotate, and then drives the first stirring rod to mix and stir the incineration fly ash and the crushed material. At the same time, the transmission shaft rotates, drives the mounting sleeve to rotate, and drives the rotating shaft to rotate around the transmission shaft. At the same time, through the cooperation between the gear and the annular gear plate, the rotating shaft rotates, and then drives the second stirring rod to rotate, thereby stirring the sediment material, making the stirring more uniform, and through the connection between the first scraper and the second scraper and the transmission shaft, the inner wall and the bottom end of the collection box can be scraped to prevent the material from sticking to the inner wall and affecting the mixing detection effect;

[0020] 4. The present invention pulls the partition so that the partition drives the connecting block and the connecting rod to penetrate away from the fixed block, and drives the limit plate to extrude the torsion spring to produce deformation, so that the partition is away from the discharge port, thereby extracting the mixed and stirred incineration fly ash and discharging it through the fan-shaped groove and the discharge port for inspection. After the qualified incineration fly ash is inspected, the partition is rotated to drive the upper end of the protrusion of the connecting block to be opposite to the bottom end of the protrusion of the trapezoidal block, thereby moving the partition away from the discharge port and supporting and fixing the partition, and then the mixed and stirred incineration fly ash is discharged from the discharge port.
