Do you know the structure of those tanker truck?

▎Advantages of powder material transport tanker

Truckers who have transported bagged cement know that in the rainy season, it is more troublesome to load, transport and unload. Once the cement package is exposed to water, the cement powder will deteriorate and agglomerate, and finally lose its use, causing economic losses to users. .

Bulk cement tankers can also be loaded, transported, and unloaded in the factory normally during the rainy season. The closed tank body does not need to worry about water entering, and it also saves labor costs for loading and unloading, as well as cement packaging costs.

▎Development history of powder material transportation tanker

The powder material transport tanker is used to transport dust materials within 0.1mm in diameter. In addition to bulk cement, it can also transport coal ash, lime powder and other goods.

The first powder tankers that appeared were unloaded by gravity, and it was designed like the current dump truck, except that the tank was fully sealed. The disadvantages of this unloading method are obvious. For example, powder materials with a diameter of less than 0.1mm cannot be unloaded by gravity unloading. They can only be unloaded to the lowest point of the container itself, and the self-flow speed is also very weak, so it was eliminated.

▎The structure of the powder material transport tanker

Just looking at the appearance, the structure of the powder tanker is a large tank with a few pipes, which is not complicated at all. In fact, as you can imagine, its design is really not complicated, and the welding process is relatively more important.

But it is worth mentioning that the design of the tank body also needs to be rationally designed, using the computer to show the actual shape of the product, and analyzing the structural mechanical properties through structural features, so that the load-bearing capacity and stress area of the tank body can be more reasonable. , improve the service life.

Compared with the appearance, the internal structure is the most attractive. The design structure of the fluidized bed inside the tank is the essence of the entire tank. In order to reduce the amount of material left at the bottom of the tank, many bulk cement tankers have replaced the iron lining at the bottom of the tank with aluminum alloy material. The inclination angle of the tank is very important, which can determine the fluidity and residual amount of the internal material.

The common bulk cement tanker on the market has a standard load of about 35-36 tons, and the unloading time is about 20-30 minutes. This depends on the margin of the construction site storage tank and the size of the air pressure. Determine the size of the discharge port, and use the triangle principle to fix the discharge pipe inside the tank to ensure that the discharge pipe will not shift during the unloading process. Generally, as long as the sealing strip on the top of the tank does not leak air, The unloading time is not long.

In the early days, a large diesel engine was installed in front of the tank, but today's lightweight trailers directly connect the air compressor to the gearbox as power, which can greatly reduce the weight of the vehicle and reduce the number of pipes required. Reduce the operation steps of unloading and improve operational efficiency.

▎How to choose a tanker in the current market

The difference between a lightweight carbon steel tanker (weight 6.15-6.5 tons) and an aluminum alloy tanker (weight about 5.0 tons) is about 1 ton. In addition, when returning empty, the lighter weight can also reduce vehicle fuel consumption and tire wear. , On the other hand, the aluminum alloy tank body has high corrosion resistance, a longer life cycle, and low self-weight is not easy to be eliminated by the market. Therefore, it is recommended that you choose an aluminum alloy tank truck when buying a tanker truck.

There is another key point here. If you buy an aluminum alloy tanker, you must know the local after-sales service network. The aluminum alloy tanker of the big brand will have after-sales service. Once there is cracking and desoldering, you can go to the service station to repair it as soon as possible. To reduce the hardware damage of the vehicle, in the later process of using the vehicle, everyone should pay more attention to the chassis structure of the tanker, and repair it in time if any problems are found.

In daily use, the tanker is very durable. In addition to the regular maintenance of tires and axles, the interior of the tank also needs to be cleaned regularly to protect the runner at the bottom of the tank. Cleaning up the remaining cement material can also reduce the weight of the vehicle, usually once a year. Clean the appearance of the tank when you have time to reduce the adhesion of cement dust. Strong corrosiveness will also affect the strength of the tank, and the second-hand residual value of the well-maintained tank will be higher.
