Description

Technical Field

[0001] This utility model belongs to the field of hazardous waste stabilization treatment technology, and in particular relates to a material pool for a hazardous waste stabilization treatment workshop. Background Technology

[0002] Hazardous waste stabilization is a technical method for treating hazardous waste, aiming to transform harmful substances in hazardous waste into forms that are less soluble, migrating, and diffused, thereby reducing their harm to the environment and human health. Stabilized hazardous waste effectively reduces the leaching of harmful substances, lowering the risk of pollution to soil, water, and air, protecting the ecological environment and human health. Furthermore, stabilized hazardous waste is more stable in form, potentially reducing its volume, facilitating transportation and storage, and providing convenience for subsequent safe landfill or other disposal methods. Due to the large volume requirements for hazardous waste stabilization and the increased standards for water-soluble salts and organic matter in hazardous waste, the collection and storage of fly ash, slag, sediment, sludge, and other hazardous wastes with single or multiple water-soluble salt or organic matter exceeding the standards necessitates mixing and blending before landfilling. For environmental reasons, hazardous waste can be directly fed into a mixing tank after unloading and mixed according to a formulation plan; after mixing, the hazardous waste can be transferred to a transfer container and then to the stabilization production line for stabilization production, thereby increasing capacity and addressing shortcomings in compliant disposal.

[0003] Currently, hazardous waste is typically mixed in the material storage pits using an excavator, and then the excavator's grab bucket places the waste into the stabilization production line's hopper. Most existing material storage pits are made of concrete, and the excavator's grab bucket inevitably bumps against the pit walls during mixing, especially during the grabbing and releasing process. Without reinforcement, this directly impacts the pit's lifespan. Furthermore, while some pits have steel plates on the walls, the size of the pit (e.g., 4200mm x 3500mm x 3200mm) makes it difficult to apply a single steel plate, resulting in numerous gaps. Finally, due to the pit's depth, the lack of speed bumps around the perimeter poses safety hazards when the excavator switches positions. Utility Model Content

[0004] This utility model addresses the technical problems existing in the aforementioned hazardous waste stabilization pools by proposing a stabilization pool for hazardous waste treatment workshops that is rationally designed, structurally strong, easy to assemble, and highly safe.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: the material pool for the hazardous waste stabilization treatment workshop provided by this utility model includes a concrete pool body. The concrete pool body has a cubic structure and a steel plate assembly is installed inside it. The steel plate assembly includes four vertical angle steels located at the four corners of the concrete pool body. Side steel plates that fit against the inner wall of the concrete pool body are arranged between adjacent vertical angle steels. A central steel plate distributed diagonally is provided at the bottom of the concrete pool body. Both ends of the central steel plate are 90-degree right angles. The two sides of the central steel plate... The structure consists of two triangular steel plates, which together form a cubic steel plate structure with an open top. This cubic steel plate structure is fitted to the inner wall of the concrete pool. Four bottom angle steels, connected end-to-end in a U-shape, are located on the inner bottom edge of the cubic steel plate structure. Four top angle steels, connected end-to-end in a U-shape, are located on the outer top of the cubic steel plate structure. One side of each top angle steel is attached to the inner wall of the cubic steel plate structure, and the other side is attached to the top of the concrete pool. Four speed bumps are distributed around the outer top of the concrete pool.

[0006] Preferably, the mating surfaces of adjacent bottom angle steels are at a 45° angle and are connected by welding, and the mating surfaces of adjacent top angle steels are at a 45° angle and are connected by welding.

[0007] Preferably, the wall thickness of the steel plate cubic structure is 14 mm.

[0008] Preferably, the top surface of the speed bump is arc-shaped, and multiple countersunk holes are provided near both sides of the speed bump. At least one pair of positioning clips are provided between the speed bump and the top angle steel.

[0009] Preferably, the positioning clip includes a bottom segment, which is attached to the bottom surface of the speed bump and the top angle steel. The bottom segment is provided with a clamping section integrally formed therewith. The clamping section is provided with an arc-shaped opening and through holes on both sides of the arc-shaped opening. The through holes are connected to the countersunk holes by screws.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This utility model provides a material pool for a hazardous waste stabilization treatment workshop. By breaking down the steel plate components into smaller parts, particularly by using vertical angle steel and intermediate steel plates, the assembly difficulty of the steel plate components is reduced. Furthermore, the top and bottom edges of the steel plate components are reinforced by bottom and top angle steel, requiring only separate welding of the top and bottom angle steel, thus reducing the amount of welding work involved in attaching the steel plates. The inclusion of speed bumps improves the safety of the mixing equipment moving near the concrete pool. This device is rationally designed, has high structural strength, is easy to assemble, and offers high safety, making it suitable for large-scale deployment. Attached Figure Description

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Examples, such as Figures 1-7 As shown, the material pool for the hazardous waste stabilization treatment workshop provided by this utility model includes a concrete pool body 1. The concrete pool body 1 has a cubic structure and a steel plate assembly 2 is installed inside it. The steel plate assembly 2 includes four vertical angle steels 21 located at the four corners of the concrete pool body 1. Side steel plates 22 that fit against the inner wall of the concrete pool body 1 are installed between adjacent vertical angle steels 21. A middle steel plate 23 distributed diagonally is provided at the bottom of the concrete pool body 1. Both ends of the middle steel plate 23 are 90-degree right angles. There are two triangular steel plates 2 on both sides of the middle steel plate 23. 4. Angle steel 21, side steel plate 22 and triangular steel plate 24 form a steel plate cubic structure with an open top. The steel plate cubic structure is attached to the inner wall of the concrete pool 1. Four bottom angle steels 25 are connected end to end in a U-shape on the inner bottom edge of the steel plate cubic structure. Four top angle steels 26 are connected end to end in a U-shape on the outer top of the steel plate cubic structure. One side of the top angle steel 26 is attached to the inner wall of the steel plate cubic structure and the other side is attached to the top of the concrete pool 1. Four speed bumps 3 are distributed around the top of the concrete pool 1.

[0028] Specifically, the concrete pool 1 has dimensions of 4200mm x 3500mm x 3200mm, and its interior uses steel plate components 2 to improve the structural strength of the entire inner wall. More specifically, the steel plate components 2 provided by this invention are designed to be modular, particularly by using angle steel 21 and intermediate steel plate 23. The angle steel 21 and intermediate steel plate 23 can be installed before other steel plates, effectively reducing the area of ​​other steel plates, lowering the installation difficulty on the sides and ground of the concrete pool 1, minimizing the gaps at the joints, and improving the integrity of the entire cubic steel plate structure.

[0029] Furthermore, the bottom angle steel 25 and top angle steel 26 provided by the present invention can respectively form the bottom and top reinforcement protection of the cubic structure of steel plates. The mating surfaces of adjacent bottom angle steels 25 are at a 45° angle and are connected by welding. The mating surfaces of adjacent top angle steels 26 are at a 45° angle and are connected by welding. Only the top angle steel 26 and bottom angle steel 25 need to be welded separately. Other steel plates can be selectively spot welded, which reduces the amount of welding work for mounting steel plates. Moreover, the recycling rate of these steel plates is also guaranteed to a certain extent.

[0030] In order to improve the utilization rate and service life of the steel plate assembly 2, the wall thickness of the steel plate cubic structure provided by this utility model is 14mm. This thickness can ensure that the excavator grab bucket will not damage the concrete pool 1 when working against the wall, and can also control the cost of the steel plate cubic structure within a reasonable range.

[0031] For safety reasons, this invention improves the safety of the mixing equipment moving near the concrete pool 1 by setting speed bumps 3. Specifically, the top surface of the speed bump 3 is arc-shaped for deceleration, and multiple countersunk holes 31 are provided near both sides of the speed bump 3. At least one pair of positioning clips 4 are provided between the speed bump 3 and the top angle steel 26. Ordinary speed bumps 3 require several blind holes to be drilled in the ground for fixed connection, while this utility model uses positioning clips 4 to position the speed bump 3. If the excavator travels around the speed bump 3 and a slope is created, it will stop moving forward. The impact and friction on the speed bump 3 are reduced, and the positioning of the speed bump 3 by the positioning clips 4 can effectively meet the deceleration warning requirements.

[0032] To improve the practicality of the positioning clamp 4, the positioning clamp 4 provided by this utility model includes a bottom segment 41, which is attached to the bottom surface of the speed bump 3 and the top angle steel 26. A clamping section 42 integrally formed therewith is provided on the bottom segment 41. The clamping section 42 has an arc-shaped opening with through holes on both sides, and the through holes are connected to the countersunk hole 31 by screws 43. In this way, the bottom of the positioning clamp 4 is pressed down by the top angle steel 26, while the clamping section 42 is connected to the speed bump 3 by screws 43. When the speed bump 3 is subjected to impact and friction, the clamping opening formed by the clamping section 42 and the bottom segment 41 presses down on the speed bump 3, preventing it from flipping over and ensuring the stability of the speed bump 3's distribution around the material pool.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
