Description

Technical Field

[0001] The utility model belongs to the technical field of powder conveying, in particular to a sanitary detachable cleaning gas powder blowing device. Background Art

[0002] In food and pharmaceutical processing, powder conveying often involves the use of rotary discharge valves. This separates the gas from the powder and then uses a Roots blower to blow the powder to the conveying location. However, rotary discharge valves are very expensive and difficult to disassemble and clean, making them unsuitable for conveying food and pharmaceutical powders requiring high hygiene standards.

[0003] In order to solve the above problems, the existing technology uses a powder injector to transport powder. However, there are two defects in the use of the powder injector: first, if the nozzle is installed in an unreasonable position at one time, it cannot be adjusted online and can only be adjusted after disassembly and assembly, and the number of adjustments is large; second, at the output end, powder is retained on the pipe wall. Utility Model Content

[0004] In order to solve the problems in the background technology, the utility model provides a sanitary detachable cleaning gas powder blowing device. The nozzle tube of the utility model can be adjusted online, and the best nozzle tube installation position can be found in the shortest time. The nozzle tube is provided with spiral ribs inside, so that the ejected air flow is spiral. The spiral air flow can rotate off the powder retained on the wall of the powder mixing tube to avoid powder retention on the tube wall.

[0005] The utility model provides a sanitary detachable cleaning gas powder blowing device, comprising a powder collecting hopper, a blowing tee, an air inlet pipe and a powder mixing pipe, the powder collecting hopper is connected to the upper end of the blowing tee, the air inlet pipe and the powder mixing pipe are respectively connected to the two ends of the blowing tee, the powder collecting hopper, the air inlet pipe and the powder mixing pipe are connected to the blowing tee by a clamp, so as to facilitate disassembly, a nozzle pipe is provided in the air inlet pipe, the nozzle pipe extends into the blowing tee, the two ends of the outer wall of the nozzle pipe are respectively matched with the air inlet pipe and the blowing tee for sliding sealing, the outer wall of the blowing tee is provided with a long hole, and the nozzle pipe is provided with a long hole. A push block is fixedly connected to the outer wall, and the push block extends from the long hole outside the blowing tee. A fixed block is fixedly connected to the outer wall of the blowing tee, and an adjusting bolt is arranged between the fixed block and the push block. By rotating the adjusting bolt, the nozzle tube is moved axially, thereby adjusting the position where the negative pressure is generated in the blowing tee, avoiding the problem of powder leakage caused by a poor installation position. The inner wall of the nozzle tube has spiral ribs, so that the gas flowing through the nozzle tube is spiral, and then the airflow sprayed into the powder mixing tube is spiral. The spiral airflow can send out the powder retained on the tube wall, reducing the amount of powder retained on the tube wall.

[0006] A further technical solution is: the powder collecting hopper is a funnel-shaped structure, and a plug is provided inside the lower end of the plug. A movable plug rod is connected above the plug, which can move up and down and rotate; the plug is in the shape of an inverted cone, the upper part of the plug can be sealed with the powder collecting hopper, and a stirring needle is provided at the lower part of the plug.

[0007] A further technical solution is that a pneumatic drive device is provided above the powder collecting hopper, and the pneumatic drive device drives the plug rod to move up and down and rotate.

[0008] A further technical solution is: the stirring needle is made of stainless steel and is detachably mounted on the plug. Beneficial effects

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. The powder collecting hopper, air inlet pipe, powder mixing pipe and blowing tee of this application are all connected by clamps. The detachable connection is more convenient for cleaning, and the disassembly and assembly speed of the clamp connection is fast, which is conducive to improving work efficiency.

[0011] 2. The nozzle tube of the present application can be moved online and can be adjusted to the optimal position in the shortest time.

[0012] 3. The inner wall of the nozzle tube of the present application is provided with spiral ribs, so that the airflow ejected from the nozzle tube is spiral. The spiral airflow can carry away the powder retained on the wall of the powder mixing tube, thereby reducing retention.

[0013] 4. This application uses a plug instead of a valve, which has a simpler plug structure and is easier to clean. In addition, the stirring needle at the bottom of the plug can break up and stir the powder when it is clumping or the material is not flowing smoothly, ensuring smooth material feeding.

[0020] like Figure 1 As shown, this embodiment discloses a sanitary detachable cleaning gas powder blowing device, including a powder collecting hopper 4, a blowing tee 3, an air inlet pipe 1 and a powder mixing pipe 8. The powder collecting hopper 4 is connected to the upper end of the blowing tee 3, and the air inlet pipe 1 and the powder mixing pipe 8 are respectively connected to the two ends of the blowing tee 3. The powder collecting hopper 4, the air inlet pipe 1 and the powder mixing pipe 8 are connected to the blowing tee 3 by a clamp 2, so as to facilitate disassembly and cleaning, and the clamp 2 has a fast disassembly and assembly speed, which is conducive to improving work efficiency.

[0021] like Figure 1-2 As shown, a nozzle tube 9 is provided in the air intake pipe 1, and the nozzle tube 9 extends into the blowing tee 3. The two ends of the outer wall of the nozzle tube 9 are respectively slidably sealed with the air intake pipe 1 and the blowing tee 3. The outer wall of the blowing tee 3 has a long hole 14. The outer wall of the nozzle tube 9 is fixedly connected with a push block 11. The push block 11 extends from the long hole 14 outside the blowing tee 3. The outer wall of the blowing tee 3 is fixedly connected with a fixing block 13. An adjusting bolt 12 is provided between the fixing block 13 and the pushing block 11. By rotating the adjusting bolt 12, the nozzle tube 9 is moved axially, thereby adjusting the position where the negative pressure is generated in the blowing tee 3, avoiding the problem of powder emitting due to poor installation position. The nozzle tube 9 of this embodiment can move online and can be adjusted to the optimal position in the shortest time, and the adjustment is continuous.

[0022] like Figure 3 As shown, the inner wall of the nozzle tube 9 is provided with spiral ribs 10, so that the gas flowing through the nozzle tube 9 is spiral, and the airflow sprayed into the powder mixing tube 8 is spiral. The spiral airflow can deliver the powder retained on the tube wall, reducing the amount of powder retained on the tube wall.
