The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0025] Please see Figures 1 to 2 A dryer for precisely discharging powder includes a tank 1, on which an inlet 11 and an outlet 12 are provided. The inlet is located at the top of the tank and the outlet is located at the bottom of the tank. A heating mechanism (not shown) and a stirring shaft 2 are installed inside the tank. A vibration assembly 3 is installed on the outside of the side wall of the tank. The vibration assembly 3 includes at least one vibrating block 32 that can reciprocate in a direction perpendicular to the side wall of the tank to impact the side wall of the tank. A stirring blade 21 is installed on the stirring shaft 2. The stirring blade is inclined downward to prevent powder accumulation.

[0026] The vibration assembly 3 also includes a fixed base 31 that is connected and fixed to the tank body. A receiving groove 312 is provided on the side of the fixed base near the tank body. The vibration block is located in the receiving groove 312. A push hole 311 is also provided in the fixed base. One end of the vibration block extends into the push hole. A push rod 33 is provided in the push hole that is connected to the vibration block and can push the vibration block closer to or away from the fixed base along the push hole.

[0027] The diameter of the end of the push hole 311 away from the vibrating block is larger than the diameter of the end closer to the vibrating block. The outer diameter of the end of the vibrating block that extends into the push hole is larger than the diameter of the end of the push hole closer to the vibrating block so that the push hole forms a limiting structure for the vibrating block to prevent the vibrating block from slipping. A buffer spring 34 is also provided in the push hole, and the buffer spring is located between the push rod and the vibrating block.

[0028] The vibrating block 32, the push hole 311 and the push rod 33 are multiple of each other. A synchronization seat 35 is provided on the side of the fixed seat away from the vibrating block. Each push rod is connected and fixed to the synchronization seat. A driving device 36 is connected to the side of the synchronization seat away from the push rod to synchronously drive each push rod to reciprocate.

[0029] The drive device 36 is specifically a combination of one or more of the following: a cam assembly, a hydraulic telescopic rod assembly, and an electrically driven telescopic rod assembly, which can drive the synchronous seat to reciprocate towards or away from the fixed seat.

[0030] A rubber sheet 321 is fixed to the side of the vibrating block 32 near the tank body. The side wall of the tank body 1 is made of elastic metal material to facilitate deformation and vibration upon impact. When the vibrating component strikes the side wall of the tank body, the side wall undergoes slight deformation to generate side wall vibration, shaking off the dust. It should be noted that the striking force needs to be adjusted according to the specific material of the tank body. At the same time, cushioning pads such as cotton cloth or foam layers can be used to buffer the impact and prevent excessive impact from affecting the service life of the tank body.

[0031] The tank body 1 is also provided with a purging mechanism 4. The purging mechanism includes an air inlet pipe 41 extending from the outside of the tank body into the inside of the tank body and a purging pipe located in the tank body and connected to the air inlet pipe. The purging pipe is provided with multiple purging air ports 42, which point to each stirring blade 21.

[0032] A support mechanism 5 is installed on the outside of the tank body 1. The support mechanism includes a clamp that fits around the outer wall of the tank body. The clamp includes at least one pair of semi-circular rings that fit together and are adjustable in position.

[0033] The clamp includes an upper clamp 51 located on the upper part of the outer side of the tank body and formed by a pair of clamp rings. A slide rail 53 is provided above the tank body 1, and a pair of telescopic rods 52 that can move along the slide rail are installed on the slide rail. The two telescopic rods are respectively connected and fixed to the two clamp rings of the upper clamp.

[0034] The clamp also includes a lower clamp 54 located on the lower part of the outer side of the tank body and formed by a pair of clamp rings. The clamp rings of the lower clamp are respectively fixedly connected to at least one support rod 55 installed on the ground.

[0035] The dryer for precise powder output in this embodiment accurately measures the material before feeding. After the material is fed into the dryer, it is stirred and dried by the dryer. After the drying process is completed, the outlet is opened to output the powder. At this time, the vibration component 3 and the blowing mechanism 4 work. Under the action of the push rod, the vibrating block repeatedly hits the side wall of the tank, so that the powder adhering to the side wall can be dislodged under vibration. At the same time, the blowing mechanism blows the stirring blades, so that the powder remaining on the stirring blades can also be completely separated from the stirring blades under the action of airflow.

[0036] The beneficial effects of this utility model are: by combining the vibration component and the purging mechanism, the powder in the dryer tank is vibrated and purged, reducing the powder residue in the tank, effectively controlling the accuracy of the metering during the powder conveying process, which is beneficial to the control of the amount of powder used in subsequent processes and improving product quality.

[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications and variations to the above embodiments within the scope of the present invention.
