the principle and composition of powder tanker
Product overview of powder tanker: powder tanker, the full name of powder material transporter, is suitable for bulk transportation of powder and dry materials such as fly ash, cement, lime powder, ore powder, granular alkali and other particles whose diameter is not greater than 0.1mm.Powder material transporter is a kind of special vehicle widely used in industry, agriculture, commerce, power plant, construction, etc. Second, the advantages of powder tanker: the powder particles are not packaged in paper bags from the factory, transported and stored, directly Shipped by powder tanker.
Therefore, powder tanker has the following advantages: 1. Reduce labor consumption, increase labor productivity, and improve labor conditions; 2. Save raw materials and paper bag packaging and crushing costs, and reduce transportation costs; 3. Reduce cement loss, and the loss rate is generally 0% 5 or less, and the bag loss rate is greater than this ratio; 4. To ensure the quality of cement, bulk cement is not easily affected by moisture during transportation, and powder tanker is rarely deteriorated after one year of storage; 5. Reduce environmental pollution;
Product structure and working principle of powder tanker: 1. Product structure Powder tanker car chassis and powder bulk transportation special device is composed of two parts; 2. The upper part mainly includes four parts: transmission system, tank body, pipeline system, auxiliary device and sub-beam; 3. Powder tanker working principle: The power of the automobile engine is transmitted to the air compressor through the power take off, transmission shaft and other mobile devices, and the compressed air generated by the air compressor enters the tank body, and the powder material is liquefied through the liquefaction device. The powder material is transported to the designated position along the discharge pipeline with the air; 4. Introduction to the fluidization of the powder:
After the gas enters the powder layer from the lower part of the container, if the gas flow rate exceeds a certain value (0.015m/m for cement) s), the friction between the gas and the powder is equal to the weight of the powder, and the powder is no longer supported by the fluidized bed. At this time, they can move freely and flow from high to low, so that the upper part of the powder layer The plane remains horizontal, with liquid-like properties. If there are holes in the side wall of the container at this time, the powder can also be ejected from the holes. This is called fluidization. The cement truck utilizes the fluidization characteristics of the powder to realize unloading. The function of the fluidized cloth is to compress the air to form a fine and uniform air flow into the powder layer to fluidize the powder;
Sub assembly structure and working principle 1. The main head of the tank, the cylinder body, the human body It is composed of hole cover and liquefaction device; a. The head adopts standard elliptical head, the main specifications are EH2300, EH2400, EH2500, EH2600, EH2700mm.b head, cylinder material is Q345, QST420, 610, etc.; c. Manhole The cover adopts two structures, one is the inner button type hole cover (the height of the whole vehicle is 100mm lower than that of the external pressure spring lifting structure after loading, but the operation maneuverability is poor and the operation is troublesome), and the other powder tanker is an external three claw external pressure type. Manhole cover (high height, good maneuverability and easy operation), the standard configuration is an inner button manhole cover. c.
The internal fluidization device is the core component of the powder tanker, mainly including a canvas-type liquefaction device (composed of a perforated plate, a side slide, and the supporting structure below, and the powder tanker perforated plate and the side slide form a certain angle with the horizontal plane.
