Screw conveyor is also called auger conveyor. It is a commonly used conveying equipment. It is widely used in chemical, building materials, metallurgy and grain industries to transport powdery, granular and small materials with low viscosity and difficult to change. In actual use, there are still some serious problems, such as accidents, vibration, jamming, transmission parts damage and so on. Today Xiaobian teaches you how to solve the problem of screw conveyor jam. To solve the problem of the screw conveyor jam, it is necessary to solve the problem before the material enters the spiral. It is essential to prevent the debris from entering the spiral. For example, the granular or powdery material should be added with a mechanical screen in front of the conveyor, or you can try to change the spiral and The inner shell is matched, for example, the inner shell is changed so that the spiral edge is embedded in the spiral spiral track of the inner shell to form a seamless spiral conveying, and the material and the foreign matter are in a completely closed spiral space, so as to achieve the effect of no jamming.
The screw conveyor usually consists of a screw conveyor body, an inlet and outlet device, and a driving device. The body of the screw conveyor consists of three parts: the head section, the middle section and the tail section.
Under normal circumstances, the intermediate section of the screw conveyor is arranged in order of length in the final assembly. The longer intermediate section is close to the head section, and the middle section of the same length is twisted together. If there are special requirements, the arrangement is given when ordering. order. A thrust bearing is arranged in the head section of the screw conveyor to receive the axial force, and a screw shaft is supported by the bearing in the middle section and the tail section. Further, an axially movable radial bearing is arranged in the tail section of the screw conveyor to Compensate for errors in the length of the screw shaft and adapt to changes in temperature.
The spiral conveyor has a spiral surface in the form of a solid spiral (S method) and a belt spiral (D method). Flange connection between each screw shaft ensures the interchangeability of the coupling shaft and is convenient for maintenance. The screw conveyor cover is tile-shaped and clamped on the casing with a cover buckle. If the sealing performance needs to be improved, the user can add waterproof and coarse canvas between the cover and the casing. The screw conveyor enters and discharges the device with a feeding port, a square discharge port, a push-type discharge port, and a rack-type discharge port. The user opens the hole on the body at the use site. When arranging the screw conveyor, the position of the discharge port should be ensured to ensure the distance from the material to the end, and avoid the contact between the material inlet and the sling bearing oil cup, the casing coupling flange and the base.
Another benefit of vitamins for the human body is that it can help the growth and development of the human body to operate normally, especially for teenagers, vitamins are one of the essential nutrients in the growth process. For example, vitamin D can well adjust the metabolism of some trace elements in the human body, and can also promote the absorption of calcium by the human body, maintain bone health, and maintain a balance between the blood phosphorus level and the blood calcium level in the human body.
