Detailed Implementation

[0026] The following are specific implementation cases and appendices. Figures 1 to 4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0027] A hazardous waste solidification device, such as Figures 1 to 4As shown, the hazardous waste solidification device includes: a mounting plate 10, a support frame 11, a mixing tank 12, a conveying pipe 13, a first conveying hole 14, a stirring paddle 15, a second conveying hole 16, a rotating shaft 17, and a spiral blade 18; two support frames 11 are mounted on the mounting plate 10, and there is a gap between the two support frames 11; the mixing tank 12 is a hollow cavity, located between the two support frames 11, and both ends of the mixing tank 12 are rotatably connected to the two support frames 11 respectively; the conveying pipe 13 is a hollow cavity, passing through both ends of the mixing tank 12 in sequence, and the conveying pipe 13 is rotatably connected to both ends of the mixing tank 12; multiple The first feed port 14 is located inside the mixing tank 12, and multiple first feed ports 14 are arranged on the outer wall of the feed pipe 13; the stirring paddle 15 is a hollow cavity with an opening at the end, multiple stirring paddles 15 are located inside the mixing tank 12, multiple stirring paddles 15 are installed on the outer wall of the feed pipe 13, and the opening of the stirring paddle 15 is connected to the first feed port 14; multiple second feed ports 16 are arranged on the outer wall of the stirring paddle 15; the rotating shaft 17 passes through both ends of the feed pipe 13 in sequence, and the rotating shaft 17 is rotatably connected to the feed pipe 13; multiple spiral blades 18 are located inside the feed pipe 13, and multiple spiral blades 18 are fitted on the outside of the rotating shaft 17.

[0028] By mounting two support frames 11 on the mounting plate 10, the mixing tank 12 is positioned between the two support frames 11, and both ends of the mixing tank 12 are rotatably connected to the two support frames 11 respectively, so that the two support frames 11 cooperate to support the mixing tank 12, thereby enabling the mixing tank 12 to rotate between the two support frames 11; by passing the conveying pipe 13 through both ends of the mixing tank 12 in sequence, and rotatably connecting the conveying pipe 13 to both ends of the mixing tank 12, the mixing tank 12 supports the conveying pipe 13, thereby enabling the conveying pipe 13 to rotate inside the mixing tank 12. By setting multiple first feed holes 14 on the outer wall of the feed pipe 13, and welding multiple agitators 15 onto the outer wall of the feed pipe 13, with the openings of the agitators 15 connected to the first feed holes 14, the curing agent in the feed pipe 13 can enter the agitator 15 through the first feed holes 14. By setting multiple second feed holes 16 on the outer wall of the agitator 15, the curing agent in the agitator 15 can flow out through the second feed holes 16. By passing a rotating shaft 17 sequentially through both ends of the feed pipe 13 and rotatably connecting the rotating shaft 17 to the feed pipe 13, the feed pipe 13 supports the rotating shaft 17, allowing the rotating shaft 17 to rotate within the feed pipe 13. By mounting multiple spiral blades 18 on the outside of the rotating shaft 17, the rotating shaft 17 can drive the multiple spiral blades 18 to rotate, allowing the spiral blades 18 to move the curing agent within the feed pipe 13, thereby enabling the curing agent to enter each agitator 15.

[0029] When using the product, first pour the curing agent into the delivery pipe 13; then, rotate the shaft 17, causing the shaft 17 to drive multiple spiral blades 18 to rotate, thereby causing the multiple spiral blades 18 to move the curing agent within the delivery pipe 13; since multiple agitators 15 are installed on the outer wall of the delivery pipe 13, and the openings of the agitators 15 are connected to the first delivery hole 14, when the curing agent moves within the delivery pipe 13, the curing agent flows into the agitators 15 through the first delivery hole 14 (the curing agent first enters the lower agitator 15 due to gravity, and then...). After a set time, rotate the feed pipe 13 to move the upper stirring paddle 15 to the lower position so that the subsequent curing agent can enter the stirring paddle 15; then, pour the hazardous waste into the mixing tank 12; then, rotate the feed pipe 13 to drive the multiple stirring paddles 15 to rotate, so that the curing agent in the stirring paddle 15 flows out through the second feed hole 16 due to centrifugal force, thereby mixing the curing agent with the hazardous waste; at the same time, rotate the mixing tank 12 in the opposite direction to make the mixing tank 12 drive the hazardous waste to rotate, thereby mixing the curing agent with the hazardous waste together.

[0030] By adopting the above structure, multiple agitators 15 are installed on the outer wall of the feed pipe 13, the openings of the agitators 15 are connected to the first feed hole 14, and multiple second feed holes 16 are set on the outer wall of the agitators 15. This allows the curing agent poured into the feed pipe 13 to flow into the multiple agitators 15. When the feed pipe 13 drives the agitators 15 to rotate, the curing agent flowing into the agitators 15 can flow out through the second feed holes 16 due to centrifugal force. This allows the curing agent to be fully mixed with the hazardous waste in various parts of the mixing tank 12. Compared with pouring the curing agent into one place, the mixing effect of the curing agent and the hazardous waste is better, thereby improving the curing effect of the hazardous waste.

[0031] In embodiments of this utility model, such as Figures 1 to 4 As shown, the hazardous waste solidification device further includes: a first inlet 19, an outlet 20, a second inlet 21, a base plate 22, and an inclined mechanism 23; the first inlet 19 is located at the top of one end of the mixing tank 12; the outlet 20 is located at the bottom of the other end of the mixing tank 12; the second inlet 21 is located at the top of one end of the conveying pipe 13; the base plate 22 is located below the mounting plate 10, and the base plate 22 is rotatably connected to the end of the mounting plate 10 near the outlet 20; the inclined mechanism 23 is mounted on the base plate 22, and the inclined mechanism 23 is in contact with the end of the mounting plate 10 near the first inlet 19.

[0032] By setting the first inlet 19 at the top of one end of the mixing tank 12, hazardous waste can be poured into the mixing tank 12 through the first inlet 19; by setting the outlet 20 at the bottom of the other end of the mixing tank 12, the material in the mixing tank 12 can flow out through the outlet 20, so as to facilitate the recycling of the material; by setting the second inlet 21 at the top of one end of the conveying pipe 13, the curing agent can be poured into the conveying pipe 13 through the second inlet 21. By placing the base plate 22 below the mounting plate 10 and rotatably connecting the base plate 22 to the end of the mounting plate 10 near the discharge port 20, the mounting plate 10 can rotate relative to the base plate 22. By installing the tilting mechanism 23 on the base plate 22 and attaching the tilting mechanism 23 to the end of the mounting plate 10 near the first feed port 19, the tilting mechanism 23 can drive the mounting plate 10 to tilt and rotate, thereby achieving an inclined state inside the mixing tank 12. This allows the material inside the mixing tank 12 to move towards the discharge port 20 due to gravity, ensuring that the material can flow out from the discharge port 20 and improving the user experience of the product.

[0033] Specifically, valves are provided in the first inlet 19, the second inlet 21 and the outlet 20 to prevent material from flowing out of the mixing tank 12 or the conveying pipe 13 when the mixing tank 12 and the conveying pipe 13 are rotated.
