Description

Technical Field

[0001] The utility model relates to the technical field of powder tank trucks, in particular to an air compressor assembly for powder tank trucks. Background Art

[0002] Powder tank trucks are specialized vehicles for transporting low-density dry goods in powdered or granular form. Examples include bulk cement, flour, fly ash, concrete admixture powders, talcum powder, and other powdered items. Their operating principle is to utilize a power source to drive an air compressor (hereinafter referred to as the air compressor). This compressed air is then piped into the air chamber at the bottom of the sealed tank, causing the powder particles in the fluidized bed to suspend and flow. When the pressure within the tank reaches a certain level, the discharge valve opens, allowing the fluidized material to flow through the pipe for transport, completing the unloading process.

[0003] Existing air compressors for powder tankers have a simple structure and a single function. The air compressor is directly connected to the tanker's air chamber and lacks air storage. It starts when unloading and remains idle when not in use. As is well known, the air compressor requires a certain amount of time to start before it can provide compressed air at the appropriate pressure for unloading. This long wait time hinders efficiency. Furthermore, after unloading, the tank interior and exterior sometimes require cleaning. While the interior can be cleaned with compressed air, the exterior cannot be cleaned and requires other fans or manual labor, making this a cumbersome task. Utility Model Content

This part of the stored air can be used for unloading the powder material from the tank truck, and one end of the hose 8 on the winch 7 can be connected to the air tank 6. This part of the compressed air is used to blow the outside of the tank truck to clean the tank truck, which is convenient and practical. Moreover, when cleaning, the length of the hose is adjustable and can be rolled up and extended, which is suitable for cleaning every corner of the tank truck, and reduces the space occupied by the tank truck when rolled up.

[0029] Preferably, a locking pin is slidably mounted on the baffle 13 on the side of the winch 7 , and the turntable 14 of the winch 7 is provided with pin holes evenly distributed around the circumference and adapted to the locking pin.

[0030] The locking pin cooperates with the pin hole to temporarily fix the turntable 14 of the winch 7 to prevent it from rotating, thereby ensuring a certain telescopic length of the hose. Then, one end of the hose 8 on the winch 7 is connected to the gas tank 6, and this part of the compressed gas is used to blow the outside of the tank truck to clean the tank truck.
