Description

Technical Field

[0001] This utility model relates to the field of powder material conveying technology, and in particular to an automatic powder material docking device. Background Technology

[0002] In the production processes of powder materials in industries such as chemical, petrochemical, environmental protection, pharmaceutical, pesticide, and fine chemical industries, the powder conveying process after drying needs to be completed under negative pressure to connect upstream and downstream equipment in order to meet the process requirements for airtightness, cleanliness, and production efficiency. Currently, the industry commonly uses transfer tanks and mobile transfer tanks to achieve material transfer. Although these devices can basically complete the material transfer function, they have limitations in practical applications.

[0003] On the one hand, the large size of transfer tanks and mobile transfer tanks requires independent storage and operation space, resulting in a loose production line layout. Especially in scenarios with limited workshop space, this significantly reduces the installation and maintenance space for other equipment, hindering the compact design of the production line. On the other hand, after materials enter the transfer device from the upstream equipment, they need to be manually handled or mechanically transferred to the downstream equipment. The transfer process not only extends the total material transportation time and reduces production continuity, but also increases the risk of material loss due to multiple loading, unloading and transfers, making it difficult to meet the high-efficiency requirements of modern continuous production lines.

[0004] Meanwhile, existing connection equipment has shortcomings in cleaning and maintenance. The inner surfaces of key channels such as the feed inlet are prone to residue buildup after long-term powder material transport. Because the device is a closed structure, manual cleaning requires disassembling the connecting parts between the feed inlet and the support, as well as the separation and docking components, making the operation cumbersome. Furthermore, if residual dust is not removed promptly, it may cause cross-contamination and affect the purity of subsequent materials. Therefore, an automatic powder material docking device needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides an automatic powder material docking device to solve the problems of powder accumulation on the inner wall of the feed inlet of existing docking equipment, the need to disassemble parts for manual cleaning due to the sealed structure, cumbersome operation, and the risk of cross-contamination caused by residues.

[0007] This utility model embodiment adopts the following technical solution: an automatic powder material docking device. It mainly includes a support frame with a top cover. A feeding section extends through the top cover, consisting of a feeding pipe (first feed pipe) and a feeding pipe (second feed pipe). The support frame has a docking part aligned with the feeding section. A driving part is installed on the support frame to achieve docking and fitting between the docking part and the feeding section. A blowing part for removing residual powder from the inner wall of the feeding pipe is provided at the coaxial connection point between the bottom surface of the top cover and the feeding pipe. The feeding pipe (second feed pipe) has multiple locking parts for quick locking and reliable sealing between the feeding pipe (first feed pipe) and the feeding pipe (second feed pipe).

[0008] Furthermore, the blowing part includes a movable sleeve fixed to the bottom surface of the top cover and coaxially sleeved outside the feed pipe. An air inlet pipe is connected to the movable sleeve. Multiple sets of air nozzles are arranged circumferentially on the inner wall of the movable sleeve, and the ends of the air nozzles extend into the inside of the feed pipe.

[0009] Furthermore, the locking part includes protruding seats fixed to the two sides of the feed tube. The second feed tube is provided with a notch groove that matches the protruding seat. A gripping rod is movably connected to the protruding seat. The gripping rod is linked to a pressing rod through a connecting rod. One end of the pressing rod is movably hinged to the protruding seat, and the other end is provided with a pressing block. The end of the first feed tube near the second feed tube extends outward with a protruding ring. The corresponding end of the second feed tube is provided with a step. The first feed tube overlaps the step through the protruding ring. A sealing gasket is provided at the contact point between the two.

[0010] Furthermore, a vibration motor is installed on the second feed pipe, and the vibration motor is fixed to the outer wall of the second feed pipe by a shock absorber.

[0011] Furthermore, a rotary cylinder is fixedly installed on the inner wall of the bracket, and a rotary cover is connected to its rotating end. When the device is in a non-conveying state, the rotary cylinder drives the rotary cover to rotate, and the adapter structure of the rotary cover makes it fit tightly against the sealing ring to form double sealing protection.

[0012] Furthermore, the docking part includes a lower base plate disposed on the bracket, a fixed seat connected to the lower base plate, a discharge port disposed through the fixed seat, a docking block disposed at one end of the discharge port near the inlet pipe, and a sealing ring made of silicone rubber installed on the upper surface of the docking block.

[0013] Furthermore, the drive unit includes two sets of lifting cylinders mounted on the fixed base. The two sets of lifting cylinders are symmetrically distributed. The telescopic ends of the lifting cylinders are rigidly connected to a support plate. The support plate is sleeved on the outer wall of the discharge pipe to form a synchronous lifting structure. Two sets of guide rods are installed on the lower base plate. The two sets of guide rods are arranged obliquely and symmetrically along the diagonal direction of the support plate. The corresponding positions of the support plate are movably sleeved with the guide rods through a sliding sleeve.

[0014] Furthermore, a silicone rubber guide ring is fitted onto the outside of the docking block.

[0015] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0016] An automatic powder material docking device, through the integrated design of support, top cover and feeding section, eliminates the need for traditional independent transfer tanks / transfer tanks. The support uniformly supports the top cover, feeding section and docking section, reducing the equipment's footprint. At the same time, the docking and fitting drive unit automatically docks the feeding section and the docking section, replacing manual handling and transfer, improving production continuity, and adapting to the high-efficiency requirements of modern continuous production lines. Meanwhile, the blowing section on the bottom of the top cover can actively blow away residual powder on the inner wall of the feeding pipe. Combined with multiple locking parts of the second feeding pipe, it simplifies the tedious disassembly process of manual cleaning in a closed structure, and can promptly remove residues, avoid cross-contamination, ensure material purity, and effectively solve the cleaning and maintenance defects of existing docking equipment.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-5 As shown in the figure, the present invention provides an automatic powder material docking device, including a support 1, which is made of stainless steel square tube and is used to support and fix the entire device. A top cover 5 is provided on the top of the support 1 to form an upper closed structure of the device. An inlet 4 is passed through the top cover 5. The inlet 4 is composed of an inlet pipe 41 and an inlet pipe 42. The inlet pipe 41 is firmly connected and fixed to the center of the top cover 5 through a flange, forming a powder inlet channel that can be adapted to different conveying needs, so as to realize the orderly introduction of powder materials.

[0029] Furthermore, a docking part is provided on the support 1. This docking part includes a lower base plate 6 on the support 1, and a fixing seat 7 is connected to the lower base plate 6 by fixing bolts. A discharge port 8 is provided through the fixing seat 7, allowing the powder to be smoothly output through the discharge port 8. A docking block 9 is provided at the end of the discharge port 8 near the inlet pipe 42. The docking block 9 is a key component for docking the inlet part 4 and the discharge port 8. A sealing ring 10 made of silicone rubber is installed on the upper surface of the docking block 9. Silicone rubber has good elasticity and sealing performance. When the upper surface of the docking block 9 is in contact with the inlet part 4, the sealing ring 10 can tightly fill the gap, effectively preventing powder leakage, ensuring the sealing performance of the docking area, and meeting the sealing requirements under negative pressure or positive pressure conveying conditions.

[0030] Furthermore, a silicone rubber guide ring is fitted outside the docking block 9. This guide ring is a crucial component for optimizing the docking process and conveying efficiency. Utilizing the elastic properties of silicone rubber, it automatically compensates for installation errors between the inlet section 4 and the outlet pipe 8 when they dock, ensuring alignment between them and preventing docking difficulties or sealing failures due to installation deviations. Simultaneously, during powder conveying, the guide ring guides the flowing powder, ensuring it follows a proper path through the docking area. This reduces direct impact and residue between the powder and the inner wall of the docking components, effectively preventing dust from overflowing from the docking gaps. This improves the overall cleanliness and conveying efficiency of the device, creating favorable conditions for subsequent cleaning, maintenance, and continuous production.

[0031] To achieve precise alignment and fit between the upper surface of the docking block 9 and the feeding section 4, such as Figures 2-3 As shown, a drive unit is installed on the fixed base 7. The drive unit includes two sets of lifting cylinders 11 fixedly installed on the fixed base 7. The two sets of lifting cylinders 11 are symmetrically distributed to ensure balanced driving force. The telescopic ends of the lifting cylinders 11 are rigidly connected to the support plate 14. The support plate 14 is also fixedly sleeved on the outer wall of the discharge port 8 to form a synchronous lifting structure. To ensure the stability and verticality of the lifting process, two sets of guide rods 12 are fixedly installed on the bottom plate 6. They are arranged obliquely and symmetrically along the diagonal direction of the support plate 14. The corresponding positions of the support plate 14 are movably sleeved with the guide rods 12 through the sliding sleeve 13 (with built-in wear-resistant bearings), so that the support plate 14 moves smoothly and linearly along the guide rods 12 under the drive of the lifting cylinders 11, avoiding tilting and offset caused by uneven gravity, thereby ensuring that the docking block 9 fits with the lower end face of the feed part 4 and forms a reliable seal with the sealing ring 10.

[0032] To further improve the sealing performance of the device, a rotary cylinder 2 is fixedly installed on the inner wall of the bracket 1. The rotating end of the cylinder is connected to a rotary cover 3. When the device is not in the conveying state, the rotary cylinder 2 drives the rotary cover 3 to rotate. The adaptive structure of the rotary cover 3 makes it fit tightly against the sealing ring 10, forming a double sealing protection, effectively preventing external air and impurities from entering. At the same time, in conjunction with the docking of the lifting cylinder 11 and the guide rod 12, a comprehensive sealing guarantee is formed, improving the sealing performance and reliability of the device under cleaning, standby and other working conditions.

[0033] To address the issue of powder residue on the inner wall of the feed pipe, a blowing section is installed on the bottom surface of the top cover 5, coaxially connected to the feed pipe 41. This blowing section includes a movable sleeve 15 fixed to the bottom surface of the top cover 5 and coaxially sleeved outside the feed pipe 41. An air inlet pipe 16 is connected to the movable sleeve 15 for connecting to an external air supply device. Simultaneously, multiple sets of air nozzles 17 are arranged circumferentially on the inner wall of the movable sleeve 15 (the corresponding component numbers in the diagram can be adjusted according to actual conditions). The ends of the air nozzles 17 extend into the feed pipe 41. During powder conveying, external gas is sprayed through the air inlet pipe 16 and the movable sleeve 15, and then through the air nozzles 17 onto the inner wall of the feed pipe. The airflow impact force blows off the attached powder, preventing residue accumulation and ensuring the cleanliness of the feed pipe and the purity of subsequent materials. Combined with the overall docking device, this improves the continuity and stability of the powder conveying process.

[0034] To further enhance the powder cleaning effect on the inner wall of the feed pipe, a vibration motor 18 is installed on the feed pipe 42. The vibration motor 18 is fixed to the outer wall of the feed pipe 42 by a shock absorber. When the vibration motor 18 is working, it generates micro-vibrations at a specific frequency. By using the vibration inertial force, the powder adhering to the inner wall of the feed pipe 42 due to electrostatic adsorption and adhesion is shaken off. Combined with the airflow of the blowing section, a combined cleaning mode of vibration and air blowing is formed, which effectively removes residual powder in the feed pipe, avoids blockage and pollution problems caused by long-term accumulation, ensures the smooth flow of powder and the purity of materials, and improves the device's adaptability to highly adhesive and ultrafine powders.

[0035] To achieve rapid locking and reliable sealing between feed tube 1 41 and feed tube 2 42, feed tube 2 42 is equipped with multiple locking parts. Each locking part includes a protrusion 110 fixed to the side of feed tube 2 42. Feed tube 2 42 is provided with a notch that matches the protrusion 110 for easy installation and positioning. A gripping rod 111 is movably connected to the protrusion 110. The gripping rod 111 is linked to a pressing rod 113 via a connecting rod 112. One end of the pressing rod 113 is movably hinged to the protrusion 110, and the other end is provided with a pressing block 114. One end of feed pipe 41 extends outward with a protruding ring near feed pipe 42. The corresponding end of feed pipe 42 is provided with a step. Feed pipe 41 overlaps the step through the protruding ring. A sealing gasket is provided at the contact point between the two. During operation, the holding rod 111 drives the pressing rod 113 to rotate, so that the pressing block 114 presses against the step. The lever principle is used to achieve a tight lock between feed pipe 41 and feed pipe 42, ensuring the sealing performance and structural stability of the connection, and facilitating quick assembly, disassembly and daily maintenance.

[0036] Working Principle: When conveying powder materials, the first step is to lock the feed pipe 41 and feed pipe 42 together via the locking mechanism. Operating the gripping rod 111, the connecting rod 112 drives the pressing rod 113 to rotate, causing the pressing block 114 to press against the step of feed pipe 42. This, combined with the sealing gasket at the contact point between the protruding ring of feed pipe 41 and the step of feed pipe 42, achieves a preliminary seal. Subsequently, the lifting cylinder 11 drives the support plate 14 to rise smoothly along the guide rod 12, moving the discharge port 8 upwards. This causes the upper surface of the docking block 9 to align with the lower surface of the feed section 4. The elasticity of the sealing ring 10 and the silicone rubber guide ring ensures a tight connection between the feed and discharge channels. Simultaneously, the blowing unit starts, and external gas is injected through the air inlet pipe 16 and the movable sleeve 15, through the air nozzle 17, into the inner wall of feed pipe 41. This, combined with the slight vibration generated by the vibration motor 18 on feed pipe 42, removes powder adhering to the inner wall, ensuring clean material conveying.

[0037] When conveying is complete or the device is in standby mode, the lifting cylinder 11 moves the discharge port 8 down to reset, and the rotating cylinder 2 drives the rotating cover 3 to rotate and fit tightly against the sealing ring 10, forming a double seal to prevent external impurities from entering. For cleaning and maintenance, reverse the locking mechanism and release the gripping rod 111 and pressing rod 113 to quickly separate the feed pipe 41 and feed pipe 42, facilitating pipe cleaning. This achieves automatic, efficient, and clean conveying of powder materials, adapting to continuous production needs.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
