Description

Technical Field

[0001] This utility model relates to the field of fertilizer production equipment technology, and in particular to a high-efficiency mixing device for fertilizer production. Background Technology

[0002] High-efficiency mixing equipment for fertilizer production is used to mix raw materials of different components to prepare the final fertilizer product. It is commonly used in the production process of fertilizers such as chemical fertilizers, organic fertilizers, and compound fertilizers.

[0003] Most existing fertilizer mixing devices use simple stirring blades for mixing, which results in uneven mixing, low efficiency, and high energy consumption, making it difficult to meet the needs of modern fertilizer production. Therefore, we provide a high-efficiency mixing device for fertilizer production that achieves uniform mixing, high efficiency, and low energy consumption. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a high-efficiency mixing device for fertilizer production that is uniform in mixing, highly efficient, and low in energy consumption, so as to solve the above-mentioned technical problem.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A high-efficiency mixing device for fertilizer production includes a frame on which a mixing tank is mounted. The mixing tank is a vertical cylindrical structure with a conical bottom. The top of the mixing tank has a feed inlet, and the bottom of the mixing tank has a discharge outlet. A stirring mechanism is installed inside the mixing tank.

[0008] The stirring mechanism includes a fixed plate, which is installed at the feed inlet. A stirring shaft is vertically and rotatably mounted on the fixed plate and is vertically positioned at the center of the mixing tank. A drive motor is mounted on the fixed plate, and the output shaft of the drive motor is connected to the stirring shaft. A first stirring blade and a second stirring blade are mounted on the stirring shaft.

[0009] The inner wall of the mixing tank is equipped with a baffle plate, and the outer surface of the mixing tank is equipped with a controller for controlling the speed and direction of the drive motor. The use of spiral stirring blades and baffle plates can create strong convection and shearing effects, so that the materials are fully mixed and the mixing uniformity is improved.

[0010] As an improved technical solution, the outer surface of the stirring shaft has an integrally formed connecting plate, and the first stirring blade and the second stirring blade are mounted on the connecting plate to facilitate the connection and fixation of the first stirring blade and the second stirring blade.

[0011] As an improved technical solution, both the first stirring blade and the second stirring blade are spiral-shaped, and the first stirring blade and the second stirring blade rotate in opposite directions. The opposite rotation of the first stirring blade and the second stirring blade can eliminate the centrifugal force of the material during the mixing process and prevent the material from separating.

[0012] As an improved technical solution, the guide plate is spiral-shaped and staggered with the second stirring blade, and the spiral direction is the same. The guide plate can guide the flow direction of materials, improve mixing efficiency, and reduce energy consumption.

[0013] As an improved technical solution, a solenoid valve for controlling the discharge speed is installed on the discharge port, and the solenoid valve is electrically connected to the controller via a wire, so that the discharge speed of the discharge port can be controlled by the controller controlling the solenoid valve.

[0014] As an improved technical solution, the mixing tank is provided with a wear-resistant liner to improve its wear resistance.

[0015] As an improved technical solution, the outer wall of the mixing tank is provided with a heat insulation layer to facilitate heat preservation of the mixing tank.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model uses spiral stirring blades and guide plates, which can create strong convection and shearing effects, so that the materials are fully mixed and the mixing uniformity is improved.

[0018] 2. In this utility model, the stirring blades rotate in opposite directions, which can eliminate the centrifugal force of the material during the mixing process and prevent the material from separating.

In application, the material to be mixed is added to the mixing tank 2 through the feed port 201, and then the drive motor 4 is started. At this time, the output shaft of the drive motor 4 drives the stirring shaft 5 to rotate. The stirring shaft 5 drives the first stirring blade 6 and the second stirring blade 7 to rotate. When the first stirring blade 6 and the second stirring blade 7 rotate, the material forms a strong convection and shearing effect under the action of the spiral first stirring blade 6 and the second stirring blade 7 and the spiral baffle plate 8, so that the material is fully mixed.

[0035] Reference Figure 4 The outer surface of the stirring shaft 5 has an integrally formed connecting plate 501.

At this time, the output shaft of the drive motor 4 drives the stirring shaft 5 to rotate. The stirring shaft 5 drives the first stirring blade 6 and the second stirring blade 7 to rotate. When the first stirring blade 6 and the second stirring blade 7 rotate, the material forms strong convection and shearing under the action of the spiral first stirring blade 6 and the second stirring blade 7 and the spiral guide plate 8, so that the material is fully mixed. After the mixture is uniform, the solenoid valve 10 on the discharge port 202 is opened to discharge the mixed material.
