Description

Technical Field

[0001] This utility model relates to the field of mixing, and in particular to a fully automatic mixing device for the production of electrical grade magnesium oxide. Background Technology

[0002] Electrical grade magnesium oxide is the main filler material for making tubular electric heating elements. In the existing technology, the processing method of electrical grade magnesium oxide is generally to crush the block magnesium oxide, then classify the crushed magnesium oxide particles, and then mix the magnesium oxide particles of each grade in proportion through a mixer according to the actual needs of the product's tap density.

[0003] A search revealed Chinese patent application CN207872027U, which discloses an electrical magnesium oxide stirring device. The device includes a support frame and a stirring drum rotatably mounted on the support frame. Driven by a power device, the stirring drum rotates relative to the support frame. A feed inlet is formed at one end of the stirring drum, a storage bin is provided on the stirring drum corresponding to the feed inlet, and a discharge outlet is formed at the other end of the stirring drum corresponding to the feed inlet. Spiral blades are formed on the inner wall of the stirring chamber to transport the material from the feed inlet to the discharge outlet. The device also includes multiple auxiliary stirring pipes arranged radially along the stirring drum and communicating with the stirring chamber. The electrical magnesium oxide stirring device of this invention, by providing a storage bin on the stirring drum, allows the auxiliary stirring pipes to be arranged radially along the stirring drum as it rotates. This creates a height difference between the auxiliary stirring pipes and the drum, allowing the material to fall freely along the auxiliary stirring pipes under its own weight, thus improving the mixing effect.

[0004] In existing equipment, when processing magnesium oxide, the material is usually placed inside the device and stirred by a stirring mechanism. However, during the stirring process, the large amount of material can increase the resistance experienced by the stirring mechanism, thus affecting the stirring effect. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully automatic mixing device for the production of electrical grade magnesium oxide includes a mixing tank, a tank cover, and a stirring mechanism. The mixing tank is fixedly connected to the tank cover. A feed pipe is provided on one side of the mixing tank, and a discharge pipe is provided at its bottom. The stirring mechanism is located at the bottom of the tank cover. The stirring mechanism includes a stirring motor, a rotating rod, a gear set, a stirring assembly, a shaft, and a spiral blade. The rotating rod is rotatably connected to the tank cover via bearings, and the stirring motor is driven by the rotating rod. The stirring assembly is connected to the rotating rod via the gear set. The shaft is fixed to the bottom of the rotating rod, and the spiral blade is fixed to the outer wall of the shaft.

[0007] Preferably, the stirring assembly includes a connecting sleeve, multiple support plates, a rotating shaft, and multiple stirring blades; the connecting sleeve is fixedly sleeved on the outer wall of the rotating shaft; the multiple support plates are fixed at equal intervals on the circumferential outer wall of the connecting sleeve; the rotating shaft and the support plates are rotatably connected by bearings; and the multiple stirring blades are fixed in a spiral shape on the rotating shaft.

[0008] Preferably, the gear set consists of a driving gear and multiple driven gears; the driving gear is fixedly sleeved on the outer wall of the rotating rod; the driven gears are fixedly sleeved on the rotating shaft, and all of the multiple driven gears mesh with the driving gear.

[0009] Preferably, a vibration mechanism is also provided on the top of the stirring mechanism, and the vibration mechanism is connected to the stirring assembly.

[0010] Preferably, the vibration mechanism includes a support shaft, a support sleeve, a connecting spring, and an impact ball; the support shaft is fixed on the rotating shaft; the support sleeve is fixedly sleeved on the support shaft; and the impact ball is connected to the support sleeve through the connecting spring.

[0011] Preferably, a feed hopper is fixed to the top of the feed pipe, and the top opening size of the feed hopper is larger than its bottom opening size.

[0012] Preferably, the discharge pipe is provided with an openable and closable sealing plug inside.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through its set stirring mechanism, allows materials to be loaded into the mixing tank through the feed pipe during the stirring process. At this time, the stirring mechanism is activated, and the stirring mechanism will stir the materials. During this process, the spiral blades will convey the materials accumulated at the bottom of the mixing tank upwards. At the same time, the spiral blades can loosen the materials inside the mixing tank, so as to improve the stirring effect of the stirring mechanism and prevent the stirring mechanism from experiencing increased resistance due to a large amount of material during the stirring process, thereby affecting the stirring effect.

[0015] 2. This utility model, through the vibration mechanism, ensures that when the material is stirred by the stirring mechanism, the support sleeve rotates synchronously with the rotation of the shaft. At this time, the impact ball will impact the mixing tank and the rotating rod under the action of the connecting spring. The vibration generated during the impact will treat the material adhering to the inner wall of the mixing tank and the stirring mechanism, preventing the material from adhering to the mixing tank and affecting the stirring of the material.
