Description

Technical Field

[0001] The utility model relates to the technical field of hazardous waste soil recycling, in particular to a storage and unloading warehouse for organic contaminated soil. Background Art

[0002] In recent years, with the acceleration of urbanization in my country, many polluting industries previously located in urban areas have relocated from city centers, creating a large number of organically contaminated sites, particularly chemical plants. If these contaminated sites are developed and reused without remediation, they pose significant risks to human health and the ecological environment. Currently, methods for treating or remediating organic soil pollution can be categorized as physical, chemical, and biological remediation. According to the "Catalogue of Remediation Technologies for Contaminated Sites (First Batch)" published by the Ministry of Environmental Protection in 2014, as well as the current status of soil remediation technology application in China, particularly in Wuhan, soil remediation technologies suitable for organic and heavy metal contamination include barrier landfills, chemical oxidation, ex situ thermal desorption, in situ thermal desorption, soil elution, cement kiln co-processing, phytoremediation, biopile technology, and ambient temperature desorption. Cement kiln incineration technology utilizes the high temperatures, long gas residence time, high heat capacity, good thermal stability, alkaline atmosphere, and zero waste residue emissions within the cement rotary kiln to remove organic pollutants while producing cement clinker.

[0003] Hazardous waste soil from existing cement production lines is stored in warehouses. When it is used, large pieces of stone and debris need to be selected by mechanical claws, and the material needs to be unloaded manually, which results in a low degree of automation. Utility Model Content

This is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, if the terms "first", "second", etc. appear in the description of the present invention, they are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0019] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] As shown in the accompanying drawings, the present invention includes a warehouse body 1, in which a plurality of storage pools 2 are arranged in a horizontal array, a plurality of warehouse doors 3 corresponding to the storage pools 2 are provided on the front side of the warehouse body 1, a unloading device 4 is provided in the storage pool 2, and a fine material discharge port and a coarse material discharge port are respectively provided at the bottom of the storage pool 2 on the side opposite to the warehouse door 3, and a screening device 5 is provided on the fine material discharge port, a fine material conveyor 6 connected to each fine material discharge port and a coarse material conveyor 7 connected to each coarse material discharge port are provided below the warehouse body 1, and an exhaust gas collection system is provided on the warehouse body 1.

[0021] The storage pool 2 is located below the ground. From the inside to the outside, the storage pool 2 is provided with a concrete hardened base layer, a waterproof layer and a concrete wear-resistant layer, which are used to harden and prevent penetration of the storage pool 2.

[0022] The unloading device 4 is used to send the solid waste to the screening device 5 in sequence. After screening by the screening device 5, the fine material falls onto the fine material conveyor 6, and the coarse material falls onto the coarse material conveyor 7 and is then transported to the crusher for crushing. After that, it enters the decomposition furnace together with the solid waste from the fine material conveyor 6 to decompose the pollution sources in the soil, and finally enters the cement kiln in proportion as raw materials for cement production.

[0023] The waste gas collection system is used to collect waste gas in the silo 1 and make the silo 1 in a negative pressure state to prevent the waste gas from being discharged to the outside. After being collected, the waste gas first enters the grate cooler of the cement production line for preheating, and then enters the cement kiln to participate in combustion.

[0024] Furthermore, a car unloading platform 9 is provided on the top of the storage tank 2 on one side of the warehouse door 3. The car unloading platform 9 extends into the warehouse body 1 to avoid splashing outside the warehouse body 1 when unloading.

[0025] Preferably, the unloading device 4 includes a pair of longitudinal guide rails 10 and a unloading plate 11. Both ends of the pair of longitudinal guide rails 10 are movably installed in the storage tank 2 through vertical guide rails 12, and both ends of the unloading plate 11 are respectively connected to the sliders of the pair of longitudinal guide rails 10.

[0026] The longitudinal guide rail 10 and the vertical guide rail 12 are both single-row chain guide rails, which are driven by motors respectively. The longitudinal guide rail 10 is used to drive the unloading plate 11 to move forward and backward, and is used to push the soil in the storage tank 2 to the screening device 5 in sequence. The vertical guide rail 12 controls the longitudinal guide rail 10 and the unloading plate 11 to move up and down. After the unloading plate 11 pushes the upper layer of soil, the vertical guide rail 12 controls the longitudinal guide rail 10 and the unloading plate 11 to move downward a distance, and then the unloading plate 11 can continue to push the next layer of soil to the screening device 5. After the soil in a storage tank 2 is used up, the unloading plate 11 is reset, and at the same time, the unloading device 4 and the screening device 5 in the next storage tank 2 are started to ensure the continuity of raw material transportation.

[0027] Furthermore, a group of tooth plates 15 inclined toward the rear side of the bin body 1 are provided at the bottom of the discharge plate 11 .

[0028] The tooth plate 15 can protect the discharge plate 11 from wear, and is convenient for pushing stones and other debris toward the screening device 5 when pushing the soil pile, and is also beneficial for separating the soil from the discharge plate 11.

[0029] Preferably, the screening device 5 comprises multiple rotating rollers arranged in a horizontal array, rotating synchronously and in the same direction. The rollers are linked by chains and driven by corresponding motors. The rollers are tilted and mounted above the fine material discharge port, with the lower roller extending over the coarse material discharge port. A gap is provided between adjacent rollers. Soil falls onto the rollers and falls through the gap, while larger debris such as rocks follows the rotation of the rollers and is transported toward the lower end. From the coarse material discharge port, it falls onto the coarse material conveyor 7 for screening.

[0030] Furthermore, a spiral guide belt 18 is provided on the rotating roller. The spiral guide belt 18 is similar to an auger. After the soil falls on the top, it is squeezed and transported by the spiral guide belt 18. The mud blocks are squeezed and broken and can fall from the gap, while the stones will move out to the lower end.

[0031] Preferably, the exhaust gas collection system 8 includes a group of exhaust pipes 20 and an air storage tank 21 connected to the group of exhaust pipes 20. A group of exhaust ports connected to the exhaust pipes 20 are provided on the top of the warehouse body 1, and a wind pressure fan 22 is provided on the exhaust port.

[0032] The air pressure blower 22 extracts the gas in the silo 1 to form a negative pressure inside the silo. The gas storage tank 21 is used to collect the gas and stabilize the pressure so that the gas pressure entering the cement kiln for combustion remains stable.
