Description

Technical Field

[0001] The present invention relates to the technical field of suspension conveying devices, and in particular to an intelligent conveying device for preventing powder from falling and suspending for producing water-based paint. Background Art

[0002] When producing water-based paint, powdered raw materials need to be distributed into processing tanks for further processing. The powdered raw materials are transported using a suspended pneumatic conveying device. The main principle is to use a Roots blower to form a high-pressure airflow and transport it to a sealed pipe. When the powder material in the hopper is discharged into the pipe, it is mixed with the high-pressure airflow and transported to the designated location. Finally, the powder and gas are separated and the powder is transported to the designated location. The pipe is suspended and fixed to the roof through connectors, which saves space and has a long transmission distance.

[0003] The above-mentioned conveying device in the prior art has certain shortcomings when used: for powder materials with high adhesion or hygroscopic powder materials, they are often easy to adhere to the corners during pipeline transmission, causing accumulation. If not handled in time, it will cause pipeline blockage. However, the cleaning work in the prior art is generally carried out by pulse airflow cleaning, but this method has poor cleaning effect, and the fallen dirt still falls in the pipeline and needs to be further discharged by airflow. For larger dirt that falls off, the pressure of the airflow makes it difficult to discharge it, and the dirt may still adhere to other positions in the pipeline when discharged by the airflow.

[0004] In response to the shortcomings of the existing technology, the present invention provides an intelligent conveying device for powder in the production of water-based paint, which has the advantages of easy cleaning of dirt and anti-clogging.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] As introduced in the background technology, in order to solve the deficiencies in the prior art, the present application proposes an intelligent conveying device for preventing powder from falling and suspending for producing water-based paint.

[0035] Example 1: Please refer to Figures 1-4 , an intelligent conveying device for preventing powder from falling and hanging for producing water-based paint, comprising a Roots blower 1, an air pipe 2 and a hopper 3. The output end of the hopper 3 is connected to the air pipe 2. The air pipe 2 includes an output pipe 21, a vertical pipe 22 and a horizontal pipe 23. One end of the vertical pipe 22 is connected to the output pipe 21. A movable elbow 24 is connected between the other end of the vertical pipe 22 and the horizontal pipe 23. An oblique pushing component 4, a vertical pushing component 5, a cleaner 6 and a horizontal blocking component 7 are also installed at the connection between the vertical pipe 22 and the horizontal pipe 23;

[0036] The oblique pushing assembly 4 is used to drive the movable bend pipe 24 to move obliquely, forcing the movable bend pipe 24 to separate from the vertical pipe 22 and the horizontal pipe 23;

[0037] The vertical pushing assembly 5 is connected to the cleaner 6, and the vertical pushing assembly 5 is used to drive the cleaner 6 to move vertically. The horizontal blocking assembly 7 includes a plug 71 that can move horizontally, and the horizontal blocking assembly 7 is used to block the end of the movable elbow 24 connected to the horizontal pipe 23;

[0038] The cleaner 6 is used to clean the inner wall of the movable elbow 24 and collect dirt;

[0039] When dirt appears in the movable bend 24, the oblique pushing assembly 4 operates, forcing the movable bend 24 to move obliquely and separate from the horizontal pipe 23 and the vertical pipe 22, and then the vertical pushing assembly 5 and the horizontal blocking assembly 7 operate. When the horizontal blocking assembly 7 operates, it forces the plug 71 to move and blocks the movable bend 24 close to one end of the horizontal pipe 23. When the vertical pushing assembly 5 operates, it forces the cleaner 6 to move upward and connect with the bottom end of the movable bend 24. Finally, the cleaner 6 operates to clean the movable bend 24 and collect dirt.

[0040] The powder material transported by this equipment is the raw material of water-based paint. The motor and cylinder in this equipment are controlled by a PLC controller, and the air pipe 2 is installed on the roof of the factory building by hanging;

[0041] When in use, start the Roots blower 1 and output high-pressure airflow to the air delivery pipe 2. The powder raw material in the hopper 3 is mixed with the airflow when discharged and moves from the air delivery pipe 2 to the designated position, thereby realizing feeding. If dirt adheres to the movable elbow 24, first start the oblique pushing component 4. The oblique pushing component 4 drives the movable elbow 24 to move obliquely, so that the movable elbow 24 is separated from the vertical pipe 22 and the horizontal pipe 23. Then start the horizontal blocking component 7 and the vertical pushing component 5. When the horizontal blocking component 7 is running, it drives the plug 71 to move horizontally, so that the plug 71 The end of the movable bend 24 that was originally connected to the horizontal pipe 23 is just blocked. When the vertical pushing assembly 5 is running, it drives the cleaner 6 to move vertically, so that the cleaner 6 is connected to the end of the movable bend 24 that was originally connected to the vertical pipe 22, and then the cleaner 6 is started. The cleaner 6 cleans the inside of the movable bend 24 and can also collect dirt while cleaning. Finally, the vertical pushing assembly 5, the horizontal blocking assembly 7 and the oblique pushing assembly 4 are operated in sequence, so that the cleaned movable bend 24 is reset, and the movable bend 24 is reconnected to the horizontal pipe 23 and the vertical pipe 22.

[0042] By arranging the movable elbow 24, the oblique pushing assembly 4, the vertical pushing assembly 5, the cleaner 6 and the transverse blocking assembly 7, when dirt adheres to the inside of the movable rod elbow, the movable elbow 24 is first separated from other pipe fittings, and then the two ends of the movable elbow 24 are blocked by the plug 71 and the cleaner 6, and finally the cleaner 6 is used to clean it. This method can not only clean the inside of the movable elbow 24 but also collect dirt, thereby avoiding the problem of dirt falling into the pipe during cleaning and causing secondary adhesion or difficulty in discharge, and has a high degree of automation and high cleaning efficiency.

[0043] Example 2: See Figure 4-Figure 7 , different from the above embodiment, the cleaner 6 includes a vertically arranged outer sleeve 601, an inner sleeve 602 is provided inside the outer sleeve 601, the top edge of the inner sleeve 602 is connected to the inner wall of the outer sleeve 601 through an annular slope, a sieve plate 603 with the same inner diameter as the inner sleeve 602 is provided inside the inner sleeve 602, a plurality of balls 604 are provided on the top of the sieve plate 603, a transmission assembly is installed on the outer sleeve 601, and the transmission assembly is used to drive the sieve plate 603 to move vertically, and the inner sleeve 602 and the outer sleeve 601 are connected. There are also two sets of symmetrically distributed snap-in components, which are used to snap on the sieve plate 603. The transmission component includes a transmission motor 605 fixed to the outer wall of the outer sleeve 601. The output shaft of the transmission motor 605 extends to the inside of the outer sleeve 601 and is fixed with a base shaft 606. The end of the base shaft 606 is fixed with a main gear 607. A push rod 608 is provided on the surface of the main gear 607. One end of the push rod 608 is movably connected to the surface of the main gear 607. The other end of the push rod 608 is hinged with a hollow ring frame 609. The hollow ring frame 60 A spring 610 is fixed on the top of the main gear 607. The top of the spring 610 extends into the inner sleeve 602 and is fixedly connected to the bottom of the sieve plate 603. A transmission shaft 611 is provided on both sides of the main gear 607. The transmission shaft 611 is rotatably connected to the inner wall of the outer sleeve 601. A sub-gear 612 and a first bevel gear 613 are fixed on the transmission shaft 611. Two symmetrically arranged notches 614 are provided on the side wall of the inner sleeve 602. The engaging assembly includes a vertical shaft 615 located between the inner sleeve 602 and the outer sleeve 601. The vertical shaft 615 is connected by a bearing. The seat 616 is movably connected to the inner wall of the outer sleeve 601, and a cam 617 is fixed on the vertical shaft 615. The cam 617 corresponds to the position of the recess 614. The bottom end of the vertical shaft 615 is fixed with a fourth bevel gear 618. The engaging assembly also includes a horizontal shaft 619, one end of which is rotatably connected to the inner wall of the outer sleeve 601. A second bevel gear 620 and a third bevel gear 621 are fixed on the horizontal shaft 619. The second bevel gear 620 is engaged with the first bevel gear 613, and the third bevel gear 621 is engaged with the fourth bevel gear 618.

[0044] The cross-sections of the outer sleeve 601 and the inner sleeve 602 are both circular. The diameter of the top of the outer sleeve 601 matches the diameter of the end of the movable elbow 24. The annular slope allows dirt that falls into the movable elbow 24 to directly enter the inner sleeve 602. The sphere 604 is a metal ball coated with rubber. The connection point between the push rod 608 and the surface of the main gear 607 is set near the edge of the main gear 607. A cone is set at the center of the top of the hollow ring frame 609, and a spring 610 is fixed on the cone. The diameter of the hollow ring frame 609 matches the inner diameter of the inner sleeve 602, which can prevent powder material from accumulating on the hollow ring frame 609. The sieve plate 603 is provided with evenly distributed sieve holes, and the diameter of the sieve holes is smaller than the diameter of the sphere 604.

[0045] When in use, the transmission motor 605 is started. After the transmission motor 605 runs, it drives the base shaft 606 to rotate. When the base shaft 606 rotates, it drives the main gear 607 to rotate. When the main gear 607 rotates, it drives the bottom end of the push rod 608 to move, so that the top of the push rod 608 reciprocates and pushes the hollow ring frame 609 to move up and down. When the push rod 608 pushes the hollow ring frame 609 to move up, the hollow ring frame 609 drives the spring 610 to move up, and the spring 610 drives the sieve plate 603 to move up. The sieve plate 603 drives the surface of the sphere 604 to move up. At this time, the cam 617 extends into the inner sleeve 602 through the notch 614. When the sieve plate 603 moves up, it contacts the cam 617 and cannot continue to move up. When the hollow ring frame 609 continues to move up, it compresses the spring 610. At the same time, when the main gear 607 rotates, it also drives the sub-gear 612 to rotate. When the sub-gear 612 rotates, it drives the transmission shaft 611 and the first bevel gear 613 to rotate. When the first bevel gear 613 rotates, it drives the second bevel gear 620 to rotate. When the second bevel gear 620 rotates, it drives the horizontal shaft 619 and the third bevel gear 621 to rotate. When the third bevel gear 621 rotates, it drives the fourth bevel gear 618 and the vertical shaft 615 to rotate. When the vertical shaft 615 rotates, it drives the cam 617 to rotate. The cam 617 blocks the screen plate 603 for a period of time and then moves to the outside of the recess 614, releasing the engagement of the screen plate 603. Since the spring 610 is in a compressed state at this time, the screen plate 603 is pushed by the elastic force of the spring 610, and the ball 604 is bounced off. The splashing ball 604 contacts the inner wall of the movable bend pipe 24 and uses the impact and vibration to cause the dirt to fall off. The ball 604 and the dirt all fall back onto the screen under gravity. At the same time, the contact between the ball 604 and the dirt also causes the dirt to be broken, achieving a grinding effect. After repeated cleaning, the movable bend pipe 24 is cleaned.

[0046] By setting up the cleaner 6, the transmission motor 605 can eject the ball 604 into the movable bend pipe 24 after it is running. The impact and vibration generated by the ball 604 can be used to separate the dirt inside the movable bend pipe 24 and crush the dirt, thereby achieving the cleaning work inside the movable bend pipe 24 and avoiding pipe blockage.

[0047] Example 3, see Figure 6 , which is different from the above embodiment, a filter cartridge 622 is provided at the bottom end of the outer sleeve 601 , and the filter cartridge 622 is threadedly connected to the bottom end of the outer sleeve 601 .

[0048] The filter cartridge 622 is assembled and disassembled by tightening. When the cleaner 6 is running, the dirt falls off and breaks. The broken dirt passes through the screen plate 603, passes through the inner cavity of the outer sleeve 601, and finally falls into the filter cartridge 622.

[0049] The provision of the filter cartridge 622 facilitates the collection of dirt for processing or recycling.

[0050] Example 4, see Figure 8 , different from the above embodiment, the oblique pushing assembly 4 includes an oblique plate 41, and two clamps 42 are fixedly connected to both ends of the oblique plate 41. The two clamps 42 are fixedly installed on the horizontal pipe 23 and the vertical pipe 22 respectively. An oblique cylinder 43 is fixedly connected to the oblique plate 41, and the output end of the oblique cylinder 43 is fixedly connected to the movable bend 24.

[0051] The inclined plate 41 has an inclination angle of 45 degrees. In actual use, sealing rubber pads are provided on the end faces of the horizontal tube 23, the vertical tube 22, and the movable elbow 24. The provision of a clamp 42 facilitates the fixing of the inclined plate 41. At the same time, the inclined plate 41 can also improve the stability of the ends of the vertical tube 22 and the horizontal tube 23. When in use, the inclined cylinder 43 is activated, and the inclined cylinder 43 extends to drive the movable elbow 24 to move obliquely, thereby separating from the vertical tube 22 and the horizontal tube 23. Similarly, when the inclined cylinder 43 contracts, it drives the movable elbow 24 to return to its original position.

[0052] By setting up an oblique pushing component 4, the pushing of the movable bent pipe 24 is achieved through the oblique cylinder 43, which facilitates the rapid separation of the movable bent pipe 24 from the vertical pipe 22 and the horizontal pipe 23. At the same time, the oblique rod and the clamp 42 can also fix the ends of the horizontal pipe 23 and the vertical pipe 22, thereby improving the stability of the vertical pipe 22 and the horizontal pipe 23 and avoiding changes in the positions of the ends of the vertical pipe 22 and the horizontal pipe 23.

[0053] Example 5, see Figure 3-Figure 5 , different from the above embodiment, the horizontal blocking assembly 7 includes a vertical plate 72, the vertical plate 72 is fixed on the horizontal tube 23, a horizontal cylinder 73 is fixed on the vertical plate 72, the output end of the horizontal cylinder 73 is fixedly connected to the plug 71, the plug 71 is provided with an air hole 74, and a branch pipe 75 is fixed to the side of the air hole 74 close to the horizontal cylinder 73, one end of the branch pipe 75 is connected to the output pipe 21, a first valve 76 is provided on the branch pipe 75, and a second valve 77 is provided on the output pipe 21.

[0054] The plug 71 matches the diameter of the end of the movable elbow 24. One end of the branch pipe 75 connected to the air hole 74 is configured as a movable bellows, and the rest is configured as a stainless steel pipe. When powder conveying is in progress, the first valve 76 is closed and the second valve 77 is opened.

[0055] When the transverse blocking assembly 7 is in operation, the first valve 76 is opened and the second valve 77 is closed, and then the transverse cylinder 73 is extended, driving the plug 71 to block the end of the movable elbow 24, and then the Roots blower 1 is started. The airflow generated by the Roots blower 1 enters the interior of the movable elbow 24 through the branch pipe 75 and the air hole 74, and then passes through the sieve plate 603, the outer sleeve 601 and the filter cartridge 622. At this time, the airflow can dry the dirt inside the movable elbow 24, making it easier to fall off and break, and can also accelerate the broken dirt debris to pass through the sieve plate 603, which not only improves the cleaning efficiency but also improves the collection efficiency of the dirt debris.

[0056] Example 6, see Figure 5 and Figure 6 , different from the above embodiment, the vertical pushing assembly 5 includes a horizontal plate 51, the horizontal plate 51 is fixed on the vertical pipe 22, a vertical cylinder 52 is fixed on the horizontal plate 51, and a bracket 53 is fixed to the output end of the vertical cylinder 52, and the bracket 53 is fixedly connected to the side wall of the outer sleeve 601.

[0057] Among them, the bracket 53 is set to be U-shaped, and the filter cartridge 622 is located on the inner side of the bracket 53. When in use, the vertical cylinder 52 extends after operation, driving the bracket 53 and the outer sleeve 601 to move, so that the end of the outer sleeve 601 is aligned with the end of the movable bend 24, which is conducive to installing the cleaner 6 at the bottom end of the movable bend 24, facilitating subsequent cleaning work.

[0058] Example 7, see Figure 8 , which is different from the above embodiment, a gate valve 8 is installed on the movable elbow 24 , and the gate valve 8 is set at the end where the movable elbow 24 is connected to the vertical pipe 22 .

[0059] During use, before the oblique pushing assembly 4 is operated, the gate valve 8 is first started and closed to prevent the vibration when the movable elbow 24 is separated from shaking off the internal dirt, thereby causing the dirt to fall into the vertical pipe 22 or the outside. When the vertical pushing assembly 5 is operated, the gate valve 8 is opened.

[0060] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
