Description

Wear-resisting terminal box

Technical Field

The utility model relates to a pneumatic conveying technical field, concretely relates to wear-resisting terminal box.

Background

In the current pneumatic conveying industry, different classified materials are often required to be conveyed according to the production process. The traditional elbow has large conveying resistance, large abrasiveness and high tail end flow velocity to impact the stock bin rapidly. Mainly because during pneumatic conveying material, the material is in the acceleration state along pipeline inner wall transport always, and terminal material velocity of flow is high, and is big to terminal equipment impact, and operating mode and installation space that a lot of were reformed transform are a bit in the reality, and need overcome operating condition, and terminal pneumatic conveying becomes the key position, and consequently the material is very big to terminal elbow radian restriction requirement, makes the blanking that the material can be more stable become the key of being of great importance in receiving the ash storehouse. Meanwhile, the disassembly is also required to be convenient, and the tail end receiving bin is used for metering and is convenient to install and maintain. In order to solve the problem, the traditional method is to install a ceramic-lined elbow or a welded elbow at the outlet of a certain end of a conveying pipeline. Although this kind of mode has solved the direction outflow that the material can be normal, the new problem that brings is that inside lining ceramic elbow or welding elbow wear and tear fast, terminal feed bin atress is big, installation space net height, and later stage installation maintenance is with high costs, describes as follows respectively:

1. the loss of the ceramic-lined elbow and the welded elbow is fast: when the tail end pipeline is ash discharged and unloaded, the lining ceramic elbow and the welding elbow are seriously abraded along with the direct scouring of the gas in the pipeline on the pipe walls of the lining ceramic elbow and the welding elbow, and the material in the elbow is directly pressed under pressure, so that the use cost and the maintenance cost are high.

2. Poor conductivity, high installation conditions, influence of end metering: because traditional inside lining pottery or welding elbow are mostly concentric the same footpath or concentric reducing, and in order to accomplish smooth, the radius of curvature can enlarge many times, needs the installation space height. And for the welding concatenation form, the big and direct area of resistance presses the impact to receive the storehouse when resulting in the material to flow from the pipeline like this for material outlet position forms easily and blocks up and causes and receive the storehouse and take inaccurate when weighing device.
