Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a fly ash solidification treatment device. Background Technology

[0002] Fly ash refers to the lightweight, small-particle-size material produced during waste incineration. Fly ash from municipal solid waste incineration contains flue dust, chemical agents, and chemical reaction products, concentrating large amounts of heavy metals. Direct release into the atmosphere without treatment would cause severe environmental pollution. Currently, cement is used as a solidifying agent, and the fly ash is treated harmlessly through pretreatment, batching, mixing, stirring, molding, and curing. However, current fly ash solidification equipment requires transferring the mixed fly ash from the mixing device to the molding equipment during molding, leading to inefficient connection between the solidification processes. Therefore, a fly ash solidification treatment device has been designed to address this issue. Utility Model Content

[0003] In view of the shortcomings of existing environmental protection equipment, the purpose of this utility model is to provide a fly ash solidification treatment device, which has the advantages of direct molding after mixing and improved fly ash treatment efficiency.

[0004] To achieve the above objectives, the present invention provides a technical solution as follows: a fly ash solidification treatment device, comprising a mixing tank, a screw, a mixing motor, a mixing plate, an equipment support, a molding component, and a conveying mechanism. The mixing tank is fixedly connected to the top of the equipment support, and the equipment support has symmetrically arranged side plates in the middle. The molding component is arranged between the side plates and corresponds to the discharge port of the mixing tank. The molding component is used to shape the fly ash after mixing. The bottom of the equipment support is provided with a conveying mechanism corresponding to the bottom of the molding component. The screw is rotatably connected to the center of the mixing tank. The mixing motor is located at the top of the mixing tank to drive the screw to rotate. A mixing plate that fits against the inner wall of the mixing tank is fixedly connected to one side of the screw through a support.

[0005] Preferably, the molding assembly includes a feed baffle, a discharge baffle, a molding die, a feed hydraulic rod, a discharge hydraulic rod, and a molding hydraulic rod. Two molding dies are symmetrically slidably connected between the side plates via a sliding groove. The molding hydraulic rod is disposed between the molding die and the equipment support, and is used to drive the two molding dies to close or open. A feed baffle is slidably connected to the top of the molding die, and the feed baffle is in contact with the discharge port of the mixing tank. The feed hydraulic rod is disposed between the feed baffle and the equipment support, and is used to drive the feed baffle to close or open the discharge port of the mixing tank. A discharge baffle is slidably connected to the bottom of the molding die, and the discharge hydraulic rod is disposed between the discharge baffle and the equipment support, and the discharge baffle is used to block fly ash during the molding process.

[0006] Furthermore, the molding die has grooves for extrusion molding, and the two grooves form a cube when the molding dies are fitted together.

[0007] Preferably, the conveying mechanism includes a conveying motor and a conveyor belt. The conveyor belt is located at the bottom of the equipment support corresponding to the opening and closing position of the forming mold. The conveying motor is used to drive the conveyor belt to transport the formed fly ash to the curing station.

[0008] The beneficial effects of this utility model are: 1. By setting a molding component at the discharge port of the mixing tank, molding can be carried out directly after mixing, without the need to transfer the mixed fly ash to the molding equipment; 2. By controlling the extension and retraction of different hydraulic rods in the molding component, the molded fly ash can be continuously transported to the curing station, thereby reducing the number of transfers and improving the fly ash treatment efficiency.

[0016] Please see Figures 1 to 4 The embodiments of this utility model include:

[0017] A fly ash solidification treatment device includes a mixing tank 1, a screw 2, a mixing motor 3, a mixing plate 4, an equipment support 5, a molding component 6, and a conveying mechanism 7. The mixing tank 1 is fixedly connected to the top of the equipment support 5. The equipment support 5 has symmetrically arranged side plates 51 in the middle. The molding component 6 is arranged between the side plates 51 and corresponds to the discharge port of the mixing tank 1. The molding component 6 is used to shape the fly ash after mixing. The bottom of the equipment support 5 is provided with a conveying mechanism 7 corresponding to the bottom of the molding component 6. The screw 2 is rotatably connected to the center of the mixing tank 1. The mixing motor 3 is arranged at the top of the mixing tank 1 to drive the screw 2 to rotate. A mixing plate 4 that fits against the inner wall of the mixing tank 1 is fixedly connected to one side of the screw 2 through a bracket.

[0018] The molding assembly 6 includes a feed baffle 61, a discharge baffle 62, a molding die 63, a feed hydraulic rod 64, a discharge hydraulic rod 65, and a molding hydraulic rod 66. Two molding dies 63 are symmetrically slidably connected between the side plates 51 via sliding grooves. The molding hydraulic rod 66 is positioned between the molding die 63 and the equipment support 5, and is used to drive the two molding dies 63 to close or open. The top of the molding die 63 is slidably connected to the feed baffle 61, which is in contact with the discharge port of the mixing tank 1. The feed hydraulic rod 64 is positioned between the feed baffle 61 and the equipment support 5, and is used to drive the feed baffle 61 to close or open the discharge port of the mixing tank 1. The bottom of the molding die 63 is slidably connected to the discharge baffle 62, and the discharge hydraulic rod 65 is positioned between the discharge baffle 62 and the equipment support 5. The discharge baffle 62 is used to block fly ash during the molding process.

[0019] The molding die 63 has a groove 631 for extrusion molding. After the molding dies 63 are fitted together, the two grooves 631 form a cube.

[0020] The conveying mechanism 7 includes a conveying motor 71 and a conveying belt 72. The conveying belt 72 is set at the bottom of the equipment support 5 corresponding to the opening and closing position of the forming mold 63. The conveying motor 71 is used to drive the conveying belt 72 to transport the formed fly ash to the curing station.

[0021] With the above settings, its specific working principle in actual operation is as follows:

[0022] Mixing: First, pour the treated fly ash and curing agent into the mixing tank 1. Then, start the mixing motor 3 to drive the screw 2 to rotate forward. During the forward rotation of the screw 2, the screw 2 lifts the fly ash at the bottom of the mixing tank 1 to the top for mixing. The mixing plate 4, which is attached to the inner wall of the mixing tank 1, mixes the fly ash until the fly ash is fully mixed and can be molded.

[0023] Extrusion molding: The feeding hydraulic rod 64 and the forming hydraulic rod 66 are activated to retract, thereby causing the feeding baffle 61 and the forming mold 63 to open, allowing the fly ash in the mixing tank 1 to enter between the forming molds 63. At this time, the stirring motor 3 is activated to reverse. Under the obstruction of the discharge baffle 62, the fly ash in the mixing tank 1 is squeezed into the space between the forming molds 63 by the screw 2. When the space between the forming molds 63 is filled with fly ash, the stirring motor 3 is stopped. Then, the feeding hydraulic rod 64 and the forming hydraulic rod 66 are activated to extend in sequence. The extension of the feeding hydraulic rod 64 causes the feeding baffle 61 to close the discharge port of the mixing tank 1. At this time, the fly ash is located between the forming molds 63 and cannot move. When the forming hydraulic rod 66 extends, the forming molds 63 move closer to each other, compressing the fly ash into the internal groove 631 to form a dense cube, thereby completing the molding process.

[0024] After molding is completed, the discharge hydraulic rod 65 and the molded hydraulic rod are activated to retract, thereby causing the discharge baffle 62 and the molding mold 63 to open, so that the molded fly ash can fall from the molding mold 63 onto the conveyor belt and be transported to the curing station; when the molded fly ash falls onto the conveyor belt, the discharge hydraulic rod 65 and the molded hydraulic rod are activated to extend, thereby causing the discharge baffle 62 and the molding mold 63 to close.

[0025] By repeating the extrusion molding process, the molded fly ash can be continuously transported to the curing station, thereby reducing the number of transfers and improving fly ash treatment efficiency.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
