Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum mixing technology, and in particular to a phosphogypsum water-stabilized material mixing device. Background Technology

[0002] Traditional mixing equipment typically faces several major problems in the mixing of materials such as phosphogypsum and fly ash: uneven material crushing, low mixing efficiency, severe dust emissions, and high equipment maintenance costs. Phosphogypsum, as an industrial byproduct, is hard and prone to agglomeration, while fly ash consists of fine particles that are easily dispersed. Therefore, achieving efficient and uniform mixing while effectively controlling dust pollution is a pressing issue that needs to be addressed in existing technologies.

[0003] Traditional mixers often employ a single stirring or tumbling method, which frequently fails to meet the stringent requirements for particle size and uniformity of phosphogypsum water-stabilized materials. Furthermore, their complex structure and inconvenient maintenance increase operating costs for businesses. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixing device for phosphogypsum water-stabilized materials. To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A phosphogypsum water-stabilized material mixing device includes a casing, two crushing rollers, two discharge plates, and a first driving device. The top of the casing has multiple material inlets, and the bottom center has a material outlet. The material inlets are symmetrically distributed. Several crushing rods arranged in a circular array are fixedly connected to the crushing rollers. The two crushing rollers are symmetrically arranged and located below the material inlets to scatter the material sliding down from the material inlets. The discharge plates are inclined downward and installed on the inner wall of the casing to concentrate the scattered material at the material outlet. The first driving device drives the two crushing rollers to rotate.

[0006] Furthermore, each of the unloading plates is provided with a rotating drum below it. The rotating drum is rotatably installed inside the machine housing and connected to a second driving device. The second driving device drives the rotating drum to rotate, so as to concentrate the material sliding off the unloading plate into the material outlet.

[0007] Furthermore, the unloading plate is fixedly connected to the chassis.

[0008] Furthermore, the unloading plate is hinged to the machine housing, and several protrusions are fixedly connected to the rotating drum, with the unloading plate overlapping the rotating drum.

[0009] Furthermore, the end of the unloading plate is fixedly connected with several arc-shaped elastic levers arranged at intervals, and the levers overlap the rotating drum.

[0010] Furthermore, a bag filter is installed on the top of the chassis to absorb dust during mixing.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting two symmetrically distributed crushing rollers and their annular array crushing rods, large pieces of phosphogypsum can be effectively crushed into smaller particles. The material falling on the crushing rollers is lifted up by the crushing rollers, ensuring the uniformity of material particle size and mixing, thereby improving the quality of phosphogypsum water-stabilized material.

[0013] 2. The combined design of the discharge plate and the rotating drum not only guides the material to slide smoothly to the material outlet, but also drives the rotating drum to rotate through the second drive device, which further promotes the tumbling and dispersion of the material and greatly improves the mixing efficiency.

[0014] 3. Depending on the usage requirements, the unloading plate can be fixedly connected or hinged to the inner wall of the machine. The latter allows the unloading plate to swing slightly with the rotation of the drum. With the protrusions and elastic levers on the drum, the flow path of the material can be adjusted more precisely to ensure that the material falls into the material outlet in a concentrated manner, avoiding material accumulation or jamming.

[0015] 4. The equipment structure has been simplified, the number of vulnerable parts has been reduced, the workload and cost of daily maintenance and repair have been reduced, and the reliability and service life of the equipment have been improved. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] This utility model provides, for example Figure 1The illustrated phosphogypsum water-stabilized material mixing device includes a housing 1, two crushing rollers 2, two discharge plates 3, and a first driving device. The top of the housing 1 has multiple material inlets 4, and the bottom center has a material outlet 5. The material inlets 4 are symmetrically distributed. Several crushing rods 6 arranged in a circular array are fixedly connected to the crushing rollers 2. The two crushing rollers 2 are symmetrically arranged and located below the material inlets 4, respectively, for throwing the material that slides down from the material inlets 4. The discharge plates 3 are inclined downward and installed on the inner wall of the housing 1, for concentrating the thrown material at the material outlet 5. The first driving device drives the two crushing rollers 2 to rotate.

[0023] When using, such as Figure 1 As shown, two or more materials slide down through multiple material inlets 4 symmetrically distributed at the top to between two crushing rollers 2 below. The annular array of crushing rods 6 on the crushing rollers 2 rotates towards the center of the machine box 1 under the drive of the first drive device, which initially crushes and scatters the materials. Subsequently, the materials slide and concentrate along the discharge plate 3 inclined on the inner wall of the machine box 1, and are finally discharged from the material outlet 5 at the bottom center, ensuring the uniformity of material particle size and mixing, thereby improving the quality of phosphogypsum water-stabilized material.

[0024] To prevent material from accumulating on the discharge plate 3, such as Figure 1 As shown, the unloading plate 3 can be fixedly connected to the inner wall of the housing 1. Each unloading plate 3 is provided with a rotating drum 7 below it. The rotating drum 7 is rotatably installed in the housing 1 and connected to a second driving device. The second driving device drives the rotating drum 7 to rotate, so as to concentrate the material sliding down the unloading plate 3 into the material outlet 5.

[0025] To further improve the smooth flow of fine powder, such as Figure 2 As shown, the unloading plate 3 is hinged to the housing 1, and several protrusions 8 are fixedly connected to the rotating drum 7. The unloading plate 3 overlaps the rotating drum 7. As the rotating drum 7 rotates, the protrusions 8 on the rotating drum 7 cause the unloading plate 3 to shake up and down, which facilitates the material to slide off the unloading plate 3 and avoids the accumulation or jamming of small materials.

[0026] To facilitate the shaking of the unloading plate 3, such as Figure 2 , Figure 3 As shown, a plurality of arc-shaped elastic levers 9 are fixedly connected to the end of the unloading plate 3 at intervals, and the levers 9 overlap the rotating drum 7. The use of elastic levers 9 increases the vibration frequency of the unloading plate 3.

[0027] In order to absorb the dust generated during the mixing process, such as Figure 1 As shown, a baghouse dust collector 10 is installed on the top of the casing 1 to absorb dust during mixing. This reduces environmental pollution, improves the working environment, and protects the health of operators.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
