Description

[0001] The present invention relates to the technical field of suspension conveying devices, and particularly to an intelligent conveying device for preventing powder from shaking off and hanging in the production of water-based paint. Background Art

[0002] When producing water-based paint, powdered raw materials need to be delivered to a processing tank and then processed. The powder raw materials are conveyed by a suspended pneumatic conveying device. The main principle is to use a Roots blower to form a high-pressure air flow and convey it into a sealed pipeline. When the powder material in the hopper is discharged into the pipeline, it is mixed into the high-pressure air flow and transmitted to a designated position. Finally, the powder and gas are separated, and the powder is conveyed to the designated position. The pipeline is suspended and fixed on the roof through connectors, which has the characteristics of saving space and long transmission distance.

[0003] The above-mentioned conveying device in the prior art has certain deficiencies in use: for powder materials with high adhesiveness or hygroscopic powder materials, they tend to adhere to the corners during pipeline transmission, causing sedimentation. If not dealt with in time, it will cause pipeline blockage. However, the cleaning work in the prior art is generally carried out by pulsed air flow, but this method has poor cleaning effect, and the fallen dirt still remains in the pipeline and needs to be further discharged by air flow. For larger dirt that falls off, the pressure of the air flow is difficult to discharge, and the dirt may still adhere to other positions of the pipeline when being discharged by air flow.

Detailed Description of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an intelligent conveying device for preventing powder from shaking off and hanging during the production of water-based paint.

[0023] Embodiment 1: Please refer to Figures 1 - 4 , an intelligent conveying device for preventing powder from shaking off and hanging during the production of water-based paint, including a Roots blower 1, an air delivery pipe 2, and a hopper 3. The output end of the hopper 3 is connected to the air delivery pipe 2. The air delivery 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, and a movable elbow 24 is connected between the other end of the vertical pipe 22 and the horizontal pipe 23. An inclined pushing component 4, a vertical pushing component 5, a cleaner 6, and a horizontal blocking component 7 are also installed at the connection of the vertical pipe 22 and the horizontal pipe 23; The inclined pushing component 4 is used to drive the movable elbow 24 to move obliquely, forcing the movable elbow 24 to separate from the vertical pipe 22 and the horizontal pipe 23; The vertical pushing component 5 is connected to the cleaner 6. The vertical pushing component 5 is used to drive the cleaner 6 to move vertically. The horizontal blocking component 7 includes a plug 71 that can move horizontally. The horizontal blocking component 7 is used to block one end of the movable elbow 24 connected to the horizontal pipe 23; The cleaner 6 is used to clean the inner wall of the movable elbow 24 and collect dirt; When dirt appears in the movable elbow 24, the inclined pushing component 4 operates, forcing the movable elbow 24 to move obliquely and then separate from the horizontal pipe 23 and the vertical pipe 22. Then, the vertical pushing component 5 and the horizontal blocking component 7 operate. When the horizontal blocking component 7 operates, it forces the plug 71 to move to block one end of the movable elbow 24 close to the horizontal pipe 23. When the vertical pushing component 5 operates, it forces the cleaner 6 to move upward and connect to the bottom end of the movable elbow 24. Finally, the cleaner 6 operates to clean the movable elbow 24 and collect dirt.

[0024] Among them, the powder material conveyed by this device is the raw material of water-based paint. The motors and cylinders in this device are all controlled by a PLC controller. The air delivery pipe 2 is installed on the factory building roof by means of hanging and fixing; During use, start the Roots blower 1 to output high-pressure air flow into the air delivery pipe 2. When the powder raw material in the hopper 3 is discharged, it is mixed into the air flow and moves from the air delivery pipe 2 to the designated position, thus realizing material feeding. If dirt adheres to the inside of the movable elbow pipe 24, first start the oblique pushing component 4. The oblique pushing component 4 operates to drive the movable elbow pipe 24 to move obliquely, so that the movable elbow pipe 24 is separated from the vertical pipe 22 and the horizontal pipe 23. Then start the horizontal plugging component 7 and the vertical pushing component 5. When the horizontal plugging component 7 operates, it drives the plug 71 to move horizontally, so that the plug 71 just plugs one end of the movable elbow pipe 24 that was originally connected to the horizontal pipe 23. When the vertical pushing component 5 operates, it drives the cleaner 6 to move vertically, so that the cleaner 6 is connected to one end of the movable elbow pipe 24 that was originally connected to the vertical pipe 22. Then start the cleaner 6. The cleaner 6 cleans the inside of the movable elbow pipe 24 and can also collect dirt during cleaning. Finally, the vertical pushing component 5, the horizontal plugging component 7 and the oblique pushing component 4 operate successively, so that the cleaned movable elbow pipe 24 is reset, and the movable elbow pipe 24 is reconnected to the horizontal pipe 23 and the vertical pipe 22.

[0025] By setting the movable elbow pipe 24, the oblique pushing component 4, the vertical pushing component 5, the cleaner 6 and the horizontal plugging component 7, when dirt adheres to the inside of the movable rod elbow pipe, first separate the movable elbow pipe 24 from other pipe fittings, then block both ends of the movable elbow pipe 24 with the plug 71 and the cleaner 6, and finally use the cleaner 6 to achieve cleaning. This method can not only clean the inside of the movable elbow pipe 24 but also collect dirt, avoiding the problem that the dirt during cleaning falls into the pipe and causes secondary adhesion or is difficult to discharge. Moreover, it has a high degree of automation and high cleaning efficiency.

[0026] Embodiment 2: Refer to Figures 4 - 7, different from the above embodiments, the cleaner 6 includes a vertically arranged outer sleeve 601, an inner sleeve 602 is arranged 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 arranged inside the inner sleeve 602, a plurality of spheres 604 are arranged on the top of the sieve plate 603, a transmission assembly is installed on the outer sleeve 601, the transmission assembly is used to drive the sieve plate 603 to move vertically, and two groups of symmetrically distributed clamping assemblies are further arranged between the inner sleeve 602 and the outer sleeve 601, the clamping assembly is used to clamp the sieve plate 603, the transmission assembly includes a transmission motor 605 fixed on the outer wall of the outer sleeve 601, the output shaft of the transmission motor 605 extends into the outer sleeve 601 and is fixed with a base shaft 606, a main gear 607 is fixed at the end of the base shaft 606, a push rod 608 is arranged 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, a spring 610 is fixed on the top of the hollow ring frame 609, the top end of the spring 610 extends into the inner sleeve 602 and is fixedly connected to the bottom of the sieve plate 603, transmission shafts 611 are arranged on both sides of the main gear 607, the transmission shafts 611 are rotatably connected to the inner wall of the outer sleeve 601, a secondary gear 612 and a first bevel gear 613 are fixed on the transmission shafts 611, two symmetrically arranged notches 614 are arranged on the side wall of the inner sleeve 602, the clamping assembly includes a vertical shaft 615 located between the inner sleeve 602 and the outer sleeve 601, the vertical shaft 615 is movably connected to the inner wall of the outer sleeve 601 through a bearing seat 616, a cam 617 is fixed on the vertical shaft 615, the cam 617 corresponds to the position of the notch 614, a fourth bevel gear 618 is fixed at the bottom end of the vertical shaft 615, the clamping assembly further includes a horizontal shaft 619, one end of the horizontal shaft 619 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 meshes with the first bevel gear 613, and the third bevel gear 621 meshes with the fourth bevel gear 618.

[0027] Among them, the cross-sections of the outer sleeve 601 and the inner sleeve 602 are both circular. The diameter of the top end of the outer sleeve 601 matches the diameter of the end of the movable elbow 24. The annular slope enables the dirt falling into the movable elbow 24 to directly enter the inner sleeve 602. The sphere 604 is a metal sphere coated with rubber on the outside. The connection point of 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 provided at the center of the top of the hollow ring frame 609. The 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 materials 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; During use, start the drive motor 605. After the drive 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, causing the top end of the push rod 608 to reciprocally push the hollow ring frame 609 up and down. When the push rod 608 pushes the hollow ring frame 609 upward, the hollow ring frame 609 drives the spring 610 upward, and the spring 610 drives the sieve plate 603 upward. The sieve plate 603 drives the sphere 604 on its surface upward. At this time, the cam 617 extends into the inner sleeve 602 through the notch 614. When the sieve plate 603 moves upward and contacts the cam 617, it cannot continue to move upward. However, when the hollow ring frame 609 continues to move upward, it compresses the spring 610. At the same time, when the main gear 607 rotates, it also drives the secondary gear 612 to rotate. When the secondary 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. After the cam 617 blocks the sieve plate 603 for a period of time, it moves out of the notch 614, releasing the clamping of the sieve plate 603. Since the spring 610 is in a compressed state at this time, the sieve plate 603 is pushed by the elastic force of the spring 610, causing the sphere 604 to be ejected. The flying sphere 604 contacts the inner wall of the movable elbow 24, and the dirt falls off due to the impact and vibration. Both the sphere 604 and the dirt fall back onto the sieve mesh under the action of gravity. At the same time, the contact between the sphere 604 and the dirt also breaks the dirt, achieving the grinding effect. After repeating many times, the cleaning of the movable elbow 24 is realized; By setting the cleaner 6, after the drive motor 605 runs, the sphere 604 can be ejected into the interior of the movable elbow 24. The impact of the sphere 604 and the generated vibration cause the dirt inside the movable elbow 24 to break away, and the dirt can also be broken, thereby realizing the cleaning work inside the movable elbow 24 and avoiding pipeline blockage.

[0028] Example three, refer toFigure 6 , different from the above embodiments, a filter cylinder 622 is provided at the bottom end of the outer sleeve 601, and the filter cylinder 622 is threadedly connected to the bottom end of the outer sleeve 601.

[0029] Among them, the filter cylinder 622 is disassembled and assembled by screwing. When the cleaner 6 operates, the dirt falls off and breaks, and the broken dirt passes through the sieve plate 603, passes through the inner cavity of the outer sleeve 601, and finally falls into the filter cylinder 622; By providing the filter cylinder 622, it is beneficial to realize the collection of dirt for treatment or recycling.

[0030] Embodiment Four, refer to Figure 8 , different from the above embodiments, the inclined pushing component 4 includes an inclined plate 41. Two hoops 42 are respectively fixedly connected to both ends of the inclined plate 41. The two hoops 42 are respectively fixedly installed on the horizontal pipe 23 and the vertical pipe 22. An inclined cylinder 43 is fixedly connected to the inclined plate 41, and the output end of the inclined cylinder 43 is fixedly connected to the movable elbow 24.

[0031] Among them, the inclination angle of the inclined plate 41 is set to 45 degrees. In actual application, sealing rubber gaskets are provided on the end faces of the horizontal pipe 23, the vertical pipe 22, and the movable elbow 24. By providing the hoops 42, it is beneficial to fix the inclined plate 41. At the same time, the inclined plate 41 can also improve the stability of the end of the vertical pipe 22 and the end of the horizontal pipe 23. When in use, start the inclined cylinder 43, and when the inclined cylinder 43 extends, it can drive the movable elbow 24 to move obliquely, and then separate from the vertical pipe 22 and the horizontal pipe 23. Similarly, when the inclined cylinder 43 contracts, it drives the movable elbow 24 to reset; By providing the inclined pushing component 4, the pushing of the movable elbow 24 is realized through the inclined cylinder 43, which is convenient for the movable elbow 24 to quickly separate from the vertical pipe 22 and the horizontal pipe 23. At the same time, the inclined rod and the hoops 42 can also fix the ends of the horizontal pipe 23 and the vertical pipe 22, improving the stability of the vertical pipe 22 and the horizontal pipe 23 and preventing the positions of the ends of the vertical pipe 22 and the horizontal pipe 23 from changing.

[0032] Embodiment Five, refer to Figures 3 - 5 , different from the above embodiments, the horizontal blocking component 7 includes a vertical plate 72. The vertical plate 72 is fixed on the horizontal pipe 23. A horizontal cylinder 73 is fixed on the vertical plate 72. The output end of the horizontal cylinder 73 is fixedly connected to a plug 71. An air hole 74 is provided on the plug 71. A branch pipe 75 is fixed on one 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.

[0033] Among them, 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 provided with a movable bellows, and the rest is made of stainless steel pipe. When the powder conveying work is carried out, the first valve 76 is closed and the second valve 77 is opened. When the horizontal plugging assembly 7 operates, the first valve 76 is opened and the second valve 77 is closed. Then the horizontal cylinder 73 extends to drive the plug 71 to block the end of the movable elbow 24. Then the Roots blower 1 is started. The air flow 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 air flow 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.

[0034] Embodiment Six. Refer to Figure 5 and Figure 6 Differing from the above embodiments, the vertical pushing assembly 5 includes a cross plate 51 fixed on the vertical pipe 22. A vertical cylinder 52 is fixed on the cross plate 51.

[0035] Among them, the bracket 53 is U-shaped, and the filter cartridge 622 is located inside the bracket 53. During use, after the vertical cylinder 52 operates and extends, it drives 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 elbow 24, which is beneficial to installing the cleaner 6 at the bottom end of the movable elbow 24 and facilitating subsequent cleaning work.

[0036] Embodiment Seven. Refer to Figure 8 Differing from the above embodiments, a gate valve 8 is installed on the movable elbow 24, and the gate valve 8 is arranged at the connection end of the movable elbow 24 and the vertical pipe 22.

[0037] During use, before the oblique pushing assembly 4 operates, the gate valve 8 is started and closed first to prevent the vibration when the movable elbow 24 is separated from shaking off the internal dirt, so that the dirt falls into the vertical pipe 22 or the outside. Then the gate valve 8 is opened after the vertical pushing assembly 5 operates.
