Description

Technical Field

[0001] This utility model relates to the field of powder and granular material conveying technology, and specifically to a powder and granular material conveying leak prevention device. Background Technology

[0002] Screw conveyors, also known as screw conveyors, use rotating screw blades to push materials along the axial direction to achieve material transport. Screw conveyors are characterized by simple structure, convenient operation, and easy maintenance, and are widely used in various industries, especially suitable for horizontal or inclined conveying of powdery, granular, and small block materials.

[0003] For example, Chinese patent (application number CN202420434213.4) discloses a powder conveying leak-proof component, which includes: an auger conveying pipe, the auger conveying pipe being connected to a receiving tank via a discharge pipe, a detachably connected folding telescopic pipe inside the receiving tank, a guide pipe being detachably connected to the lower end of the folding telescopic pipe, and a rubber hose installed inside the folding telescopic pipe for connecting the discharge pipe and the guide pipe. In this patent, the folding telescopic pipe assists the auger conveyor in feeding. The folding telescopic pipe is a telescopic guide pipe that can connect the discharge pipe and the storage tank inlet according to their specific positions, reducing the time spent adjusting the storage tank position. The rubber hose prevents powder from getting stuck in the folding telescopic pipe, and the guide pipe makes the material drop more concentrated, reducing the amount of dust generated when the powder falls, thus avoiding material waste and being environmentally friendly.

[0004] However, in the aforementioned anti-leakage component for powder conveying, the spiral blades inside the auger conveying pipe still have a conventional structure. During powder conveying, there is a gap between the spiral blades and the inner wall of the auger conveying pipe, and they are not completely fitted. During powder conveying, some powder particles will slip through the gap, affecting the powder conveying effect. Therefore, the anti-leakage effect of the screw conveyor during powder conveying is not comprehensive enough. At the same time, since the discharge port is generally located at a high position, the operation of the folding telescopic tube extension and retraction control in the anti-leakage structure of the discharge port is inconvenient, affecting the use effect. Utility Model Content

[0005] The purpose of this invention is to provide a powder conveying leak prevention device, which aims to solve the problem of poor leak prevention effect of existing powder conveying leak prevention components.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] This utility model designs a powder conveying leak-proof device, which includes the following structural configuration:

[0008] The bracket serves as a supporting component for the device;

[0009] A screw conveyor assembly is fixedly mounted on the bracket;

[0010] A feeding device, which is disposed on the screw conveyor assembly, is used to supply the powder or granular material to be conveyed into its interior;

[0011] A drive motor is used to drive the spiral conveyor assembly.

[0012] The discharge pipe is disposed on the screw conveyor assembly;

[0013] And a dust suppression bag, which is connected to the discharge pipe to prevent powder particles from flying during the discharge process. The dust suppression bag also has the freedom to be retracted and extended.

[0014] The spiral conveyor assembly includes the following structural configuration:

[0015] A conveying pipe is fixedly mounted on the support, and the feeding device and the discharging pipe are respectively mounted on the conveying pipe and communicate with its interior;

[0016] The spiral blades are rotatably disposed inside the conveying pipe and driven to rotate by the drive motor.

[0017] An assembly groove is provided along the edge of the helical blade;

[0018] A plurality of sealing rods are arranged side by side along the extension direction of the assembly groove. One end of each sealing rod extends to the outside of the assembly groove and contacts the inner wall of the conveying pipe to seal the gap between the edge of the spiral blade and the inner wall of the conveying pipe, preventing the powder particles from slipping out of the gap during the conveying process and affecting the leak prevention effect.

[0019] And several springs, which are disposed in the assembly groove, with their two ends respectively connected to the sealing rod and the bottom of the assembly groove.

[0020] Specifically, in this powder conveying leak-proof device designed in this utility model, the assembly groove is set along the thickness direction of the spiral blade and along the edge of the blade, but does not penetrate the surface of the spiral blade. The opening of the assembly groove penetrates the edge of the spiral blade, thereby enabling one end of the sealing rod installed in the assembly groove to extend beyond the edge of the blade and contact the inner wall of the conveying pipe. The spring acts as a wear compensation device for the sealing rod. After the sealing rod wears against the inner wall of the conveying pipe, the sealing rod will shorten. At this time, the spring will push the sealing rod to move towards the inner wall of the conveying pipe to compensate, ensuring that the end of the sealing rod is always in close contact with the inner wall of the conveying pipe, thereby ensuring the leak-proof effect.

[0021] Furthermore, a powder conveying leak-proof device: the conveying pipe is inclinedly arranged on the support.

[0022] Furthermore, a powder conveying leak-proof device includes a fixed frame disposed at the end of the conveying pipe, a drive motor disposed on the fixed frame, and a spiral blade connected to the output end of the drive motor.

[0023] Furthermore, a powder conveying leak prevention device includes a connecting ring disposed outside the outlet end of the discharge pipe, and the top of the dust suppression bag is connected to the connecting ring.

[0024] Furthermore, a powder conveying leak prevention device includes a winding motor, a winding wheel, and a pull rope. The winding motor is mounted on the bracket, the winding wheel is fixedly mounted on the output end of the winding motor, and the pull rope passes through the connecting ring, with one end connected to the winding wheel and the other end connected to the bottom of the dust suppression bag. When the winding motor is running, it drives the dust suppression bag to retract or release via the pull rope.

[0025] Furthermore, a powder conveying leak-proof device includes a mounting frame disposed on the support, and the winding motor is mounted on the mounting frame.

[0026] Furthermore, a powder conveying leak prevention device further includes a counterweight ring disposed at the bottom of the dust suppression bag, and the pull rope is connected to the counterweight ring.

[0027] Furthermore, a powder conveying leak prevention device includes a sealing element disposed along the edge of the spiral blade and located on both sides of the sealing rod, for sealing the gap between several sealing rods arranged side by side.

[0028] Furthermore, a powder conveying leak-proof device: the sealing rod and the sealing element are both made of silicone.

[0029] Furthermore, a powder conveying leak-proof device includes a limiting step in the assembly groove, a limiting ring at the end of the sealing rod, a spring connected to the limiting ring, and the limiting step cooperating with the limiting ring to prevent the sealing rod from falling out of the assembly groove.

[0030] The beneficial effects of this utility model are:

[0031] This invention relates to a powder conveying leak-proof device. It comprises spiral blades, an assembly groove, several sealing rods, springs, and sealing elements. The sealing rods, installed side-by-side within the spiral blades, are pushed out by the springs and come into close contact with the inner wall of the conveying pipe. This achieves a preliminary sealing effect on the gap between the spiral blade edge and the inner wall of the conveying pipe, preventing powder leakage during conveying. Simultaneously, sealing elements are installed on both sides of the sealing rods (at the edges of the spiral blades) to further seal the gaps between the sealing rods, achieving a further sealing effect and preventing powder leakage from the gaps between the sealing rods. Therefore, the spiral conveying assembly of this application has a dual sealing effect, preventing leakage of powder from the gap between the spiral blade edge and the inner wall of the conveying pipe during powder conveying. Meanwhile, the silicone sealing rod and sealing element can fit tightly against the inner wall of the conveying pipe, ensuring a sealing effect and preventing gaps between the edge of the spiral blade and the inner wall of the conveying pipe. The setting of the sealing rod and sealing element is equivalent to making the edge of the spiral blade fit more closely with the inner wall of the conveying pipe, preventing the powder particles from slipping between the edge of the spiral blade and the inner wall of the conveying pipe during conveying, thus ensuring the conveying effect of the powder particles.

[0032] This utility model designs a powder conveying leak-proof device, which consists of a discharge pipe, connecting ring, dust suppression bag, counterweight ring, pull rope, winding motor, and winding wheel. As the powder is conveyed, it eventually exits from the discharge pipe. Starting the winding motor releases the pull rope, and the dust suppression bag is lowered under the weight of the counterweight ring. The dust suppression bag extends into the corresponding powder storage device. This not only ensures normal powder output but also prevents powder from flying during the process from the discharge pipe to the storage device. Furthermore, the flexible nature of the dust suppression bag allows for more flexible retraction and easier adjustment of the outlet direction. After the powder is conveyed, starting the winding motor drives the winding wheel to rewind the pull rope, causing the counterweight ring to rise and retract the dust suppression bag. The operation is convenient and ensures effective use. Attached Figure Description

[0041] Example 1

[0042] like Figures 1-4 As shown in the figure, this embodiment 1 designs a powder conveying leak-proof device, which includes the following specific structural configuration:

[0043] Support 1, which serves as a supporting component of the device;

[0044] The spiral conveying assembly 2 includes a conveying pipe 21, spiral blades 22, an assembly groove 23, several sealing rods 24, several springs 24, and a sealing element 26. The conveying pipe 21 is fixedly mounted on the bracket 1 and is inclined. The spiral blades 22 are rotatably mounted inside the conveying pipe 21. The assembly groove 23 is provided along the edge of the spiral blades 22 and also has a limiting step 27. The end of each sealing rod 24 is provided with a limiting ring 28. Several sealing rods 24 are arranged side by side along the extension direction of the assembly groove 23, with one end of each sealing rod 24 extending to the outside of the assembly groove 23 and meeting the inner edge of the conveying pipe 21. The wall contact is used to seal the gap between the edge of the spiral blade 22 and the inner wall of the conveying pipe 21, thereby preventing the powder particles from slipping out of the gap during the conveying process and affecting the anti-leakage effect. The limiting step 27 cooperates with the limiting ring 28 to prevent the sealing rod 24 from falling out of the assembly groove 23. The spring 25 is set in the assembly groove 23, and its two ends are respectively connected to the limiting ring 28 and the bottom of the assembly groove 23. The sealing element 26 is set along the edge of the spiral blade 22 and located on both sides of the sealing rod 24 to close the gap between several sealing rods 24 arranged side by side. The sealing rod 24 and the sealing element 26 are respectively made of silicone.

[0045] The feeding device 3 is installed on the conveying pipe 21 and communicates with its interior, and is used to provide the powder material to be conveyed into the interior of the conveying pipe 21;

[0046] A drive motor 4 is used to drive the spiral blades 22 to rotate inside the conveying pipe 21, so as to realize the spiral pushing of powder and granular materials along the axial direction of the conveying pipe 21. A fixed frame 7 is provided at the end of the conveying pipe 21, and the drive motor 4 is mounted on the fixed frame 7. The spiral blades 22 are connected to the output end of the drive motor 4.

[0047] The discharge pipe 5 is disposed on the conveying pipe 21 and communicates with its interior. A connecting ring 8 is also provided on the outside of the outlet end of the discharge pipe 5.

[0048] The dust suppression bag 6 is connected to the connecting ring 8 at its top, enabling communication with the discharge pipe 5. The bottom of the dust suppression bag 6 is equipped with a counterweight ring (steel ring) 13. The dust suppression bag 6 is used to prevent powder particles from flying during the discharge process. The dust suppression bag 6 also has the freedom to retract and release. Specifically, this freedom is achieved by setting up a winding motor 9, a winding wheel 10, and a pull rope 11. The bracket 1 is equipped with a mounting frame 12. The winding motor 9 is mounted on the mounting frame 12. The winding wheel 10 is located at the output end of the winding motor 9. The pull rope 11 passes through the connecting ring 8 and is connected at one end to the winding wheel 10. The other end is connected to the counterweight ring 13 at the bottom of the dust suppression bag 6. When the winding motor 9 rotates, the pull rope 11 can drive the dust suppression bag 6 to retract or release.

[0049] Specifically, in the above-mentioned embodiment 1: the connecting ring 8 facilitates the installation of the dust suppression bag 6 and provides a bending point for the pull rope 11, making it easier for the other end of the pull rope 11 to connect with the winding wheel 10; the assembly groove 23 provides space for the sealing rod 24 to retract, and the buffer spring 25 provides a force for the sealing rod 24 to press against the inner wall of the conveying pipe 21. The bracket 1 in embodiment 1 has two sets, and the conveying pipe 21 is fixedly installed on the bracket 1 to form an inclined structure.

[0050] In the above embodiment 1, the connecting ring 8 is fixedly installed between the discharge pipe 5 and the dust suppression bag 6. The counterweight ring 13 is specifically a steel ring. There are two sets of pull ropes 11, which are symmetrically fixedly connected to the counterweight ring 13. One end of the pull rope 11 passes through the connecting ring 8 and is connected to the winding wheel 10. The winding wheel 10 is fixedly installed on the output end of the winding motor 9.

[0051] The working principle and usage process of this utility model are as follows: In actual use, the equipment is placed in a suitable position, and the powder material to be conveyed is fed into the screw conveyor assembly 2 (conveyor pipe 21) from the feeding device 3. The drive motor 4 drives the screw blade 22 to rotate and continuously convey the powder material obliquely upward. During the rotation of the screw blade 22, the sealing rod 24 is pushed out by the action of the spring 25 and comes into close contact with the inner wall of the conveyor pipe 21. At the same time, the sealing element 26 can seal the gap between the sealing rod 24. The silicone sealing rod 24 and the sealing element 26 can adhere tightly to the inner wall of the conveyor pipe 21 to ensure the sealing effect and prevent gaps from forming between the edge of the screw blade 22 and the inner wall of the conveyor pipe 21. This makes the screw blade 22 fit more closely to the inner wall of the conveyor pipe 21, preventing the powder material from leaking out from the edge of the screw blade 22 during conveying. The powder slides through the gap between itself and the inner wall of the conveying pipe 21, thus ensuring the conveying effect of the powder. As the powder is conveyed, it will eventually be discharged from the discharge pipe 5. A powder storage device can be installed below the discharge pipe 5. The winding motor 9 is started to rotate and release the pull rope 11. Under the action of the counterweight ring 13, the dust suppression bag 6 can be lowered. The dust suppression bag 6 can be directly inserted into the corresponding powder storage device. After passing through the discharge pipe 5 and the dust suppression bag 6, the powder enters the powder storage device. The dust suppression bag 6 not only ensures the normal output of the powder, but also prevents the powder from flying excessively. Its flexible nature allows for more flexible retraction and easier adjustment of the port direction. After the powder is conveyed, the winding motor 9 can be started to rotate in the opposite direction to drive the winding wheel 10 to wind up the pull rope 11, which in turn drives the counterweight ring 13 to rise, achieving the effect of retracting the dust suppression bag 6. The operation is convenient and ensures the effect of use.

[0052] Specifically, in Embodiment 1, the setting of the counterweight ring 13 can ensure the stability of the dust suppression bag 6 and prevent it from drifting due to external wind. On the other hand, the counterweight ring 13 can cooperate with the pull rope 11. Under the gravity of the counterweight ring 13, it is easy to retract the dust suppression bag 6 or ensure the stable release of the dust suppression bag 6, so as to prevent it from drifting due to external wind and so that the dust suppression bag 6 can effectively extend into the corresponding powder storage device.

[0053] The above-described preferred embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of this utility model. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
