Description

Technical Field

[0001] This utility model relates to the field of dredged soil processing and mixing, and more specifically, to a mixing device for dredged soil solidification materials. Background Technology

[0002] Dredged soil is the main waste generated in river and port dredging projects. It usually needs to be stabilized by adding solidification materials (such as cement, lime, special solidification agents, etc.) before it can be utilized as a resource. In the solidification process of dredged soil, the mixing effect of the mixing equipment directly affects the strength and stability of the solidified body.

[0003] Existing mixing equipment mostly uses a single mixing paddle combined with top feeding, which has the following problems: dredged soil contains a large amount of water and coarse and fine particles, while the curing agent is mostly powder or low-viscosity slurry. The two have a large density difference, which easily leads to the phenomenon of stratification where the curing agent floats to the top and the dredged soil particles sink to the bottom, resulting in uneven mixing.

[0019] Example 1: Please see Figure 1-3A mixing device for dredged soil solidification materials includes a mixing tank 1, a feed pipe 2 installed on the surface of the mixing tank 1, a mixing motor 3 fixedly installed on the top of the mixing tank 1, a mixing shaft 4 fixedly connected to the output end of the mixing motor 3, a mixing blade 5 fixedly installed on the surface of the mixing shaft 4, a reciprocating mixing mechanism 6 provided on the mixing tank 1, and a discharge pipe installed at the bottom of the mixing tank 1. When mixing, the mixing motor 3 is turned on, causing it to drive the mixing shaft 4 and the mixing blade 5 to rotate, thereby mixing the material in the mixing tank 1. During the mixing process, the reciprocating mixing mechanism 6 can transport the material at the bottom of the mixing tank 1 to the inside of the mixing tank 1. Through this reciprocating motion, the mixing effect can be improved and uneven mixing can be avoided.

[0020] The reciprocating mixing mechanism 6 includes a material extraction component 61 installed on the surface of the mixing tank 1, a material distribution component 62 installed at the top of the inner cavity of the mixing tank 1, and a feeding component 63 installed at the bottom of the inner cavity of the mixing tank 1. By setting the material extraction component 61, the material at the bottom of the mixing tank 1 can be extracted to the top. By setting the material distribution component 62, the material can be distributed to various positions of the mixing tank 1 when distributing the material at the top. By setting the feeding component 63, the material can be absorbed through multiple pores during suction, which can prevent turbulence in the mixing tank 1. Through the cooperation between the material extraction component 61, the material distribution component 62 and the feeding component 63, the mixing effect of the material can be improved, and the problem of uneven mixing in the prior art can be solved.

[0021] Furthermore, the material extraction component 61 includes a material extraction pump 611 installed on the surface of the mixing tank 1. The inlet end of the material extraction pump 611 is fixedly connected to a material extraction pipe 612, and the outlet pipe of the material extraction pump 611 is fixedly connected to a discharge pipe 613. One end of both the material extraction pipe 612 and the discharge pipe 613 penetrates the interior of the mixing tank 1. By turning on the material extraction pump 611, under the action of the material extraction pipe 612, the material at the bottom of the inner cavity of the mixing tank 1 can be transported to the top of the mixing tank 1 through the discharge pipe 613, avoiding the problem of uneven mixing due to stratification.

[0022] Furthermore, the material feeding component 62 includes a material feeding disc 621 fixedly installed at the top of the inner cavity of the mixing tank 1. A wire mesh 622 is embedded in the bottom of the inner cavity of the material feeding disc 621. A pushing unit 623 is provided at the connection between the mixing shaft 4 and the material feeding disc 621. The material feeding disc 621 and the mixing shaft 4 are rotatably connected. One end of the feeding pipe 613 passes through the interior of the material feeding disc 621. When the material is transported into the mixing tank 1 through the feeding pipe 613, it is first transported into the material feeding disc 621. When the mixing shaft 4 rotates, it can drive the pushing unit 623 to rotate in the inner cavity of the material feeding disc 621. The wire mesh 622 can evenly distribute the material at various positions at the top of the inner cavity of the mixing tank 1, avoiding material accumulation. By setting the wire mesh 622, the material can be screened during material feeding, thereby improving the subsequent mixing effect.

[0023] The feeding unit 623 includes a fixing collar 6231 fixedly mounted on the surface of the stirring shaft 4. A connecting plate 6232 is fixedly connected to the surface of the fixing collar 6231, and a push plate 6233 is fixedly connected to the bottom end of the connecting plate 6232. When the stirring shaft 4 rotates, it can drive the fixing collar 6231 to rotate synchronously. With the connection of the connecting plate 6232, the push plate 6233 can rotate within the distribution plate 621, thereby distributing the material at various positions. The side of the push plate 6233... The surface is provided with a push groove 6234, which is inclined downward. When the push plate 6233 pushes the material, it can apply a downward force to the material, which facilitates the material to pass through the wire mesh 622 for cutting and spreading. A cutting mesh 6235 is embedded in the bottom of the inner cavity of the push groove 6234. By setting the cutting mesh 6235, the material that has not passed through the wire mesh 622 can be screened when the push plate 6233 pushes the material, and at the same time, the load on the stirring shaft 4 can be reduced.

[0024] Furthermore, the feeding component 63 includes a cavity ring plate 631 fixedly installed at the bottom of the inner cavity of the mixing tank 1. The top of the cavity ring plate 631 is provided with a through groove 632. One end of the extraction pipe 612 is connected to the cavity ring plate 631. The top of the cavity ring plate 631 is provided with multiple first inlets 633, and the inside of the through groove 632 is provided with multiple second inlets 634. When the extraction pipe 612 extracts the material at the bottom of the inner cavity of the mixing tank 1, the material enters the cavity ring plate 631 through the first inlets 633 and the second inlets 634, and is then extracted through the extraction pipe 612. By setting multiple extraction points, turbulence in the mixing tank 1 due to extraction can be avoided. By setting the through groove 632, interference with the discharge can be avoided.

[0025] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
