Description

Technical Field

[0001] The utility model relates to an industrial solid waste treatment device, in particular to an industrial solid waste resource utilization device. Background Art

[0002] Industrial solid waste refers to solid waste generated in industrial production activities. It is a variety of waste residues, dust and other wastes discharged into the environment during the industrial production process. It can be divided into general industrial waste and hazardous solid waste. Among them, general industrial waste includes blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, coal slag, sulfuric acid slag, waste gypsum, desulfurization ash, carbide slag, salt mud, etc.; hazardous solid waste includes hazardous solid waste. The passive storage of industrial solid waste not only occupies a large amount of land, but also causes waste of manpower and material resources, and even causes environmental pollution. Therefore, it is very necessary to treat industrial solid waste as a resource.

[0003] At present, the pH value of alkaline industrial solid waste is usually greater than 10, or even greater than 12, and it has strong alkalinity. Using alkaline industrial solid waste as an activator for gelling materials can solve the problems of high commodity cost and high energy consumption of conventional activators. The usual practice is to mix, shape, and cure a variety of alkaline industrial waste residues with water in proportion to obtain alkaline gelling materials. However, there are the following problems during production: 1. The moisture content of alkaline industrial waste residues is usually different, so the moisture content of the waste residue is first tested, then it is transported to the mixing equipment for feeding, and finally a set proportion of water is added for stirring. During transportation, the moisture content of the waste residue is prone to change due to environmental changes, resulting in inaccurate ratios and affecting product quality; 2. The moisture content of alkaline industrial waste residues is usually tested by random sampling, which is prone to detection errors, and ultimately leads to inaccurate ratios with water, affecting product quality. Utility Model Content

[0004] The purpose of the utility model is to provide an industrial solid waste resource utilization device with a reasonable structure and reliable use, to solve the problems of early detection of waste slag moisture content and large detection error, to significantly improve the accuracy of moisture content detection and to ensure product quality.

[0005] The technical solution of the utility model is:

[0006] A device for resource utilization of industrial solid waste includes a base, a stirring tank and a moisture content detector. The technical key points are: the base includes a bottom plate, left and right guide rails fixed above the bottom plate and parallel to each other, and a slidable seat body arranged above the left and right guide rails; the stirring tank is fixed above the slidable seat body; a gantry bracket is provided above the front section of the base; a first longitudinal telescopic cylinder and a moisture content detector are fixed on the top of the gantry bracket; the number of the moisture content detectors is equal to and one-to-one corresponding to the number of the first longitudinal telescopic cylinders; the cylinder rod of the first longitudinal telescopic cylinder is located below the top plate of the gantry bracket and is connected and fixed to the upper end of the detection probe of the moisture content detector; a avoidance hole for the detection probe of the moisture content detector to pass through is provided on the cover plate of the stirring tank; the number of the avoidance holes is equal to and one-to-one corresponding to the number of the detection probes.

[0008] In the above-mentioned industrial solid waste resource utilization device, a stirring motor is fixed at the center of the upper surface of the cover plate of the stirring tank, and a stirring paddle connected to the output end of the stirring motor is provided in the stirring tank.

[0009] The above-mentioned industrial solid waste resource utilization device has front and rear vertical plates at the front and rear ends of the base plate, a horizontal lead screw parallel to the left and right guide rails is provided between the front and rear vertical plates, a thread sleeve connected to the horizontal lead screw is fixed to the middle part of the bottom surface of the slidable seat body, and a motor reducer connected to the end of the horizontal lead screw is fixed on one of the front and rear vertical plates.

[0010] In the above-mentioned industrial solid waste resource utilization device, the number of the first longitudinal telescopic cylinders is four, two by two, and the two pairs of first longitudinal telescopic cylinders are symmetrically arranged on the left and right sides of the center line of the mixing tank that is in place under the gantry bracket, and the two first longitudinal telescopic cylinders in the same pair are symmetrically arranged on the front and rear sides of the center line of the mixing tank that is in place under the gantry bracket.

[0011] In the above-mentioned industrial solid waste resource utilization device, a travel switch corresponding to the slidable seat is provided on the bottom plate.

[0012] The beneficial effects of the utility model are:

[0013] When in use, the slidable seat of the base is used to drive the mixing tank to the top of the rear section of the base, the cover of the mixing tank is opened, solid waste is added thereto, and then the cover is reset. The slidable seat of the base is used to drive the mixing tank to the detection station below the gantry bracket, and each first longitudinal telescopic cylinder is started to drive the detection probe of each moisture content detector downward. The detection probe passes through the cover of the mixing tank and is inserted into the solid waste for online detection. The moisture content of the solid waste in the mixing tank is detected from multiple positions. In order to achieve a more accurate detection rate, after one detection, the detection probe is reset upward under the drive of the first longitudinal telescopic cylinder, and the stirring mechanism in the mixing tank is started to stir the solid waste. After shutdown, each detection probe is driven by the first longitudinal telescopic cylinder to repeat the above action downward and inserted into the solid waste for secondary detection. Based on the two detection signals, the staff calculates the average moisture content data as the basis for the water addition ratio. When the utility model detects the moisture content in the mixing tank, the detection time is not advanced, thereby avoiding the problem of the environment affecting the moisture content during long-term transportation. At the same time, the moisture content of solid waste residues in different directions and depths can be detected online for multiple times, which significantly improves the accuracy of moisture content detection, ensures accurate mixing ratio with water, and ensures product quality.
