Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a countercurrent extraction feeding device for a feeding machine. Background Technology

[0002] In industrial production fields such as chemical, pharmaceutical, and food processing, feeding devices are indispensable key components of reaction vessels, storage tanks, or extraction equipment, used to smoothly discharge processed materials from the equipment. Especially in processes such as countercurrent extraction, the materials are often wet, viscous, or easily agglomerated powder mixtures.

[0003] When using traditional feeding devices to process the above-mentioned types of materials, due to the inherent characteristics of the materials, they easily adhere to the inner wall of the feeding pipe during the feeding process. Over time, the adhered material gradually accumulates and hardens, resulting in a reduction in the effective cross-sectional area of ​​the feeding channel, an increase in material flow resistance, and ultimately leading to poor feeding or even complete blockage, severely affecting the continuity and efficiency of production.

[0004] To address the clogging problem, existing technologies have developed feeding devices with internal stirring or scraping mechanisms. These mechanisms can agitate the material and scrape the pipe wall while feeding, alleviating clogging to some extent. However, these internal stirring and scraping components are in direct contact and friction with the material for extended periods, making them vulnerable parts that require regular inspection, maintenance, or replacement. In existing designs, these internal mechanisms are typically integrated and fixed with the drive motor and the feeding pipe body, making disassembly extremely cumbersome. Often, the entire device must be removed from the main equipment, and multiple components must be disassembled to remove the internal mechanisms. This process is time-consuming and labor-intensive, resulting in excessive downtime for equipment maintenance.

[0005] Therefore, this utility model proposes a countercurrent extraction feeding device for a feeding machine to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a countercurrent extraction feeding device for a feeding machine, which aims to improve the problems of material easily sticking to the pipe wall and causing blockage in the existing countercurrent extraction feeding device for feeding machines, and the cumbersome and time-consuming maintenance and disassembly of the internal stirring mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a countercurrent extraction feeding device for a feeding machine, comprising a feeding pipe and a motor disposed outside the feeding pipe; the device further comprises an anti-blocking component, an upper connecting plate, a lower connecting plate, and a connecting component.

[0008] The anti-clogging component includes a rotating shaft, an impeller, and a plastic plate; the connecting component includes a housing, a fixing plate, a spring, a limiting rod, and a plug rod.

[0009] The anti-clogging component is rotatably disposed inside the feed tube. The rotating shaft is drivenly connected to the motor. The impeller is fixedly connected to the rotating shaft. A groove is provided on the impeller. The plastic plate is detachably installed in the groove. The upper connecting plate is fixedly connected to the end of the rotating shaft. The lower connecting plate is fixedly connected to the feed tube. The connecting component is detachably connected between the upper connecting plate and the lower connecting plate. A cavity is formed inside the outer shell. The fixing plate is slidably disposed in the cavity. The spring is disposed between the inner wall of the cavity and the fixing plate. The limiting rod is rotatably connected to the fixing plate and can extend out of the outer shell to be inserted and locked with the lower connecting plate. The insertion rod passes through the outer shell and is connected to the fixing plate.

[0010] Preferably, the device further includes bolts, nuts, and washers, wherein the bolts pass through the impeller and the plastic plate in sequence, and the plastic plate is locked and fixed to the impeller by the nuts and washers.

[0011] Preferably, the connecting assembly further includes a threaded rod that passes through the upper connecting plate and is threadedly connected to the housing.

[0012] Preferably, a rotating ring is fixedly connected to the free end of the threaded rod.

[0013] Preferably, a pull ring is connected to the outer wall of the housing.

[0014] Preferably, when the insertion rod is compressed, it causes the fixing plate to compress the spring, so that the limiting rod retracts back into the housing.

[0015] Preferably, the wall of the feeding pipe is connected to an inlet pipe and an outlet pipe.

[0016] Preferably, the device further includes flange fasteners, which are detachably connected to the ports of the feed pipe and the discharge pipe, respectively.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, an anti-blocking component is first installed inside the feeding pipe and driven to rotate by a motor. The impeller on the component agitates the material and the plastic plate scrapes the inner wall of the feeding pipe, which solves the problem of material easily sticking to the pipe wall, causing poor flow and blockage in the prior art. This achieves the technical effects of active anti-blocking, ensuring smooth feeding, and improving conveying efficiency.

[0019] 2. In this utility model, a quick-release connection assembly using components such as springs and insert rods is used to connect the anti-blocking assembly and the feed pipe, which solves the problem of complex and time-consuming internal mechanism maintenance and disassembly in the prior art, and achieves the technical effects of simplifying disassembly and assembly steps, shortening downtime, and significantly improving maintenance efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-5 This utility model provides an embodiment of a countercurrent extraction feeding device for a feeding machine, which aims to solve the problems of easy material blockage and cumbersome maintenance and disassembly of internal mechanisms in the existing feeding devices.

[0029] The countercurrent extraction feeding device for the feeding machine includes a feeding pipe 1 and an anti-blocking component 5 rotatably disposed inside the feeding pipe 1. The feeding pipe 1 serves as the main channel for material conveying. A motor 4 disposed outside the feeding pipe 1 is connected to the anti-blocking component 5 for driving the anti-blocking component 5 to rotate.

[0030] Specifically, the anti-clogging component 5 includes a rotating shaft 501, an impeller 502 fixedly connected to the rotating shaft 501, and a plastic plate 504 detachably mounted on the impeller 502. One end of the rotating shaft 501 is connected to the motor 4 for transmission. A groove 503 is provided on the impeller 502, and the plastic plate 504 is installed in the groove 503. When the anti-clogging component 5 rotates, the plastic plate 504 is used to scrape the inner wall of the feed pipe 1.

[0031] To enable quick assembly and disassembly of the anti-clogging component 5, the device's connection structure includes an upper connecting plate 6 fixedly connected to the end of the rotating shaft 501, a lower connecting plate 8 fixedly connected to the feed tube 1, and a connecting component 7 detachably connected between the upper connecting plate 6 and the lower connecting plate 8.

[0032] The connecting assembly 7 includes a housing 701, the interior of which forms a cavity 702; a fixing plate 704 is slidably disposed within the cavity 702; a spring 703 is disposed between the inner wall of the cavity 702 and the fixing plate 704 to provide elastic force to the fixing plate 704; a limiting rod 705 is rotatably connected to the fixing plate 704, the rod of the limiting rod 705 can extend out of the housing 701 to be inserted and locked with the lower connecting plate 8, thereby fixing the connecting assembly 7 to the lower connecting plate 8; an insert rod 706 passes through the housing 701 and is connected to the fixing plate 704, and by pressing the insert rod 706, the fixing plate 704 can be slid within the cavity 702, thereby realizing the retraction and unlocking of the limiting rod 705.

[0033] In order to ensure that the plastic plate 504 can be securely installed on the impeller 502 and is easy to replace, the device also includes a bolt 505, a nut 506 and a washer 507 for locking. During assembly, the bolt 505 passes through the pre-set through hole on the impeller 502 and the corresponding through hole on the plastic plate 504 in sequence, and the washer 507 is put on the protruding end of the bolt 505. Finally, the plastic plate 504 is detachably locked and fixed on the impeller 502 by tightening the nut 506.

[0034] To achieve a secure and adjustable fastening between the connecting assembly 7 and the upper connecting plate 6, the connecting assembly 7 also includes a threaded rod 707. One end of the threaded rod 707 is threaded to the housing 701, and the other end passes through the upper connecting plate 6. To facilitate the operator to rotate the threaded rod 707 by hand, a rotating ring 708 is fixedly connected to the free end of the threaded rod 707.

[0035] To facilitate pulling the connecting component 7 out from between the upper connecting plate 6 and the lower connecting plate 8 after unlocking, a pull ring 709 is also fixedly connected to the outer wall of the housing 701.

[0036] In order to connect the device to the external piping system, the feed pipe 1 is connected to the inlet pipe 2 and the outlet pipe 3 respectively. In order to ensure the sealing of the connection, the device also includes a flange 9, which is used to detachably seal the ports of the inlet pipe 2 and the outlet pipe 3 to the external pipeline.

[0037] Working principle: During material feeding, the external pipe is sealed to the feed pipe 2 and the discharge pipe 3 through the flange 9. Then, the motor 4 is started. The motor 4 drives the rotating shaft 501 to rotate through the transmission mechanism, which in turn drives the entire anti-clogging component 5 fixedly connected to the rotating shaft 501 to rotate synchronously inside the feed pipe 1. During the rotation, the impeller 502 and the plastic plate 504 installed on the impeller 502 work together to act on the material in the feed pipe 1. On the one hand, the rotation of the impeller 502 agitates and tumbles the material, and on the other hand, the outer edge of the plastic plate 504 continuously scrapes the inner wall of the feed pipe 1, scraping off the attached material. Through the dual action of agitation and scraping, the caking and clogging of the material during the conveying process is effectively prevented, ensuring that the material can be discharged smoothly.

[0038] When the anti-clogging component 5 needs to be repaired or replaced, the operator first presses the insertion rod 706 on the connecting component 7. The insertion rod 706 pushes the fixing plate 704 inward and compresses the spring 703 in the cavity 702. As the fixing plate 704 moves, the limiting rod 705 connected to the fixing plate 704 retracts inward and disengages from the insertion and locking state with the lower connecting plate 8. Then, the operator rotates the rotating ring 708 on the threaded rod 707 to make the threaded rod 707 unscrew from the outer shell 701, releasing the fastening to the upper connecting plate 6. Finally, by pulling the pull ring 709, the entire connecting component 7 can be removed from between the upper connecting plate 6 and the lower connecting plate 8. At this time, the anti-clogging component 5 fixed on the rotating shaft 501 can be directly pulled out from the feed tube 1. The entire disassembly process does not require complicated tools and is very convenient.
