Description

Technical Field

[0001] This utility model belongs to the field of granulation equipment technology, specifically relating to a quick disassembly and assembly device for the feed pipe of granulation equipment. Background Technology

[0002] In practical applications of biopharmaceutical granulation equipment, the feed pipe, as a key component connecting different equipment units, plays a crucial role in transferring raw materials from upstream equipment (such as mixers or conveyor systems) to the granulator via pneumatic conveying. The currently prevalent fixed feed pipe installation method has significant drawbacks: firstly, if the pipe becomes blocked, the entire pipe section must be disassembled and manually cleaned after the machine is stopped. This is not only cumbersome and time-consuming (lasting several hours), but frequent disassembly and assembly also accelerates the wear of flange seals, leading to leakage risks; secondly, traditional feed pipes often use bolts or clamps for connection—bolt disassembly is cumbersome, while clamps can easily result in insecure feed pipe installation, thus affecting disassembly and assembly efficiency. Therefore, this invention proposes a quick disassembly and assembly device for the feed pipe of granulation equipment. Utility Model Content

[0003] The purpose of this invention is to provide a quick disassembly and assembly device for the feed pipe of a granulation equipment, which can solve the above-mentioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows: This utility model provides a quick disassembly and assembly device for the feed pipe of a granulation equipment, including an outer tube and an inner sleeve that is slidably disposed inside the outer tube. A retractable inner insert is integrally provided on the inner sleeve. A feed pipe body inserted into the inner insert is sleeved on one side of the outer tube. The outer tube has symmetrically opened movable ports. Two retractable parts symmetrically distributed around the outer periphery of the feed pipe body are integrally provided on the side of the outer tube. A tightening ring is sleeved on the two retractable parts. A linkage mechanism is provided between the tightening ring and the inner sleeve. The linkage mechanism includes a linkage pull plate, a flip push plate, and a pin. The linkage pull plate consists of two pieces, symmetrically distributed around the outer periphery of the outer tube. The flip push plate consists of two pieces, located on opposite sides of the two linkage pull plates. A pin is provided above the outer tube, passing through the upper side of the two linkage pull plates and fitting into two movable holes. The two movable holes are respectively opened on the two flip push plates. The same push shaft is rotatably mounted on the upper side of the two flip push plates.

[0005] Preferably, the lower sides of the two linkage plates are respectively fitted onto two smooth shafts, the two smooth shafts are symmetrically distributed in the two movable openings, and the two smooth shafts are welded and fixed to the symmetrical sides of the outer periphery of the inner sleeve.

[0006] Preferably, the smooth shaft and the stop ear are in a locked state, and the stop ear is located on the upper side inside the movable opening. The protrusion of the stop ear inside the movable opening is level with half the height of the movable opening, and the diameter of the smooth shaft is set to two-thirds of the height of the movable opening.

[0007] Preferably, the tightening ring is movably fitted with two sliding sleeves corresponding to the two movable openings respectively. The two sliding sleeves are located between the lower opposite sides of the two flip push plates. The lower side of the flip push plate is fitted with a push-pull bolt, and the push-pull bolt is threadedly connected to the sliding sleeve.

[0008] Preferably, a fixed shaft is fixed between the two linkage pull plates, and a limiting plate is movably sleeved on the fixed shaft. The limiting plate has multiple locking grooves that engage with the push shaft.

[0009] Preferably, a sealing ring is fitted on the other side of the inner sleeve, and the sealing ring contacts the inner wall of the outer sleeve. A mounting ring corresponding to the sealing ring is fixed on the other side of the outer sleeve, and the mounting ring is installed at the feed inlet of the granulation equipment or the output outlet of the conveying equipment.

[0010] Preferably, the retaining groove of the limiting plate and the flipping push plate rotate around the pin shaft and then engage with the gripping push shaft.

[0011] The beneficial effects are: This invention, through the coordinated design of the outer casing, contraction section, and linkage mechanism, allows for the tightening and adjustment of the two contraction sections when the feed tube body is inserted into the inner insert tube. This achieves support for the inner wall and compression of the outer wall of the feed tube body, resulting in a quick and secure connection. Disassembly is achieved by simply reversing the operation. Furthermore, the retaining groove on the limiting plate maintains the tightened state of the two contraction sections, ensuring the feed tube body remains secure during use.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figure 1-3 As shown, a quick disassembly and assembly device for a granulation equipment feed pipe includes an outer tube 1 and an inner sleeve 2 slidably disposed inside the outer tube 1. A retractable inner insert 21 is integrally provided on the inner sleeve 2. A feed pipe body 6 inserted into the inner insert 21 is sleeved on one side of the outer tube 1. An open movable port 11 is symmetrically opened on the outer tube 1. Two retractable parts 12 symmetrically distributed around the outer periphery of the feed pipe body 6 are integrally provided on the side of the outer tube 1. A tightening ring 5 is sleeved on the two retractable parts 12. A linkage mechanism is provided on the tightening ring 5 and the inner sleeve 2. The linkage mechanism includes a linkage pull plate 3, a flip push plate 4, and a pin 7. There are two linkage pull plates 3, which are symmetrically distributed on the outer periphery of the outer tube 1. There are two flip push plates 4, which are located on opposite sides of the two linkage pull plates 3. A pin 7 is provided above the outer tube 1. The pin 7 passes through the upper side of the two linkage pull plates 3 and is fitted into two movable holes 42. The two movable holes 42 are respectively opened on the two flip push plates 4. The same push shaft 41 is rotatably installed on the upper side of the two flip push plates 4.

[0016] As an optional implementation, the lower sides of the two linkage pull plates 3 are respectively fitted onto two smooth shafts 22. The two smooth shafts 22 are symmetrically distributed in the two movable ports 11, and the two smooth shafts 22 are welded and fixed to the symmetrical sides of the outer periphery of the inner sleeve 2. In this way, when the two smooth shafts 22 slide in the movable ports 11, they synchronously drive the inner sleeve 2 to move, thereby causing the inner insertion tube 21 on the inner sleeve 2 to protrude outward and be inserted into the feed tube body 6.

[0017] See attached document Figure 1 and attached Figure 2The smooth shaft 22 is locked to the stop ear 11a, and the stop ear 11a is located on the upper side inside the movable opening 11. The protrusion of the stop ear 11a inside the movable opening 11 is level with half the height of the movable opening 11. The diameter of the smooth shaft 22 is set to two-thirds of the height of the movable opening 11. When the smooth shaft 22 is located on the inner side of the movable opening 11, the inner insertion tube 21 is level with the side of the contraction part 12. The distance between the stop ear 11a and the inner side of the movable opening 11 is set between 10-20mm. This allows the smooth shaft 22 to slide within the movable opening 11, and the stop ear 11a to restrict the movement of the smooth shaft 22. This, in conjunction with the linkage mechanism, enables the tightening adjustment of the two contraction parts 12.

[0018] See attached document Figure 3 Two sliding sleeves 51, corresponding to the two movable openings 11, are movably sleeved on the tightening ring 5. The two sliding sleeves 51 are located between the opposite sides of the lower side of the two flipping push plates 4. A push-pull bolt 52 is sleeved through the lower side of the flipping push plate 4, and the push-pull bolt 52 is threadedly connected to the sliding sleeve 51. In this way, when the flipping push plate 4 rotates by the pin 7, it can drive the tightening ring 5 on the push-pull bolt 52 to move closer to the outer tube 1, thereby merging and tightening the two shrinking parts 12, and then cooperating with the feed tube body 6 and the inner insertion tube 21 to achieve clamping and fixing of the inner and outer walls.

[0019] Furthermore, a fixed shaft 31 is fixed between the two linkage pull plates 3, and a limiting plate 32 is movably sleeved on the fixed shaft 31. The limiting plate 32 has multiple locking grooves 32a that engage with the push shaft 41, so that the limiting plate 32 can be freely rotated and adjusted using the fixed shaft 31.

[0020] Furthermore, a sealing ring 23 is fitted on the other side of the inner sleeve 2, and the sealing ring 23 contacts the inner wall of the outer sleeve 1. An installation ring 13 corresponding to the sealing ring 23 is fixed on the other side of the outer sleeve 1, and the installation ring 13 is installed at the feed port of the granulation equipment or the output port of the conveying equipment. The sealing ring 23 can seal the gap between the outer sleeve 1 and the inner sleeve 2 when the inner sleeve 2 moves inside the outer sleeve 1, thereby improving the sealing performance of the connection between the feed pipe and the device.

[0021] Furthermore, after the retaining plate 32's locking groove 32a and the flipping push plate 4 rotate around the pin 7, they engage with the gripping push shaft 41. This allows the gripping push shaft 41 to drive the flipping push plate 4 to rotate, causing the tightening ring 5 to shrink and press the two shrinking parts 12 onto the feed tube body 6. At the same time, the retaining plate 32 can rotate to drive the corresponding locking groove 32a to reset and restrict the gripping push shaft 41.

[0022] Using the above structure, the following steps are included: 1. Tightening and Adjustment Stage Initial state: After the feed tube body 6 is inserted into the inner tube 21, the linkage pull plate 3 drives the inner sleeve 2 to move outward through the smooth shaft 22, so that the inner tube 21 is inserted into the inner wall of the feed tube and fits. At this time, the smooth shaft 22 slides along the movable port 11 to the position of the stop ear 11a (moving distance 10-20mm). The stop ear 11a restricts the smooth shaft 22 from moving outward further, ensuring that the inner tube 21 is flush with the side of the contraction part 12. Tightening action: The operator presses down on the push shaft 41, causing the two flipping push plates 4 to flip outward around the pin 7. The flipping push plates 4 pull the sliding sleeve 51 and the tightening ring 5 towards the contraction section 12 through the push-pull bolt 52. The tightening ring 5 presses the two contraction sections 12 inward and clamps the outer wall of the feed pipe body 6, achieving double fixation inside and outside. 2. Restriction and Regulation Phase Locked state: When the tightening ring 5 presses against the contraction part 12, the flipping push plate 4 rotates to a certain angle, and the gripping push shaft 41 aligns with the locking groove 32a on the limiting plate 32. The operator rotates the limiting plate 32 to make the locking groove 32a engage with the gripping push shaft 41, preventing the flipping push plate 4 from springing back and maintaining the clamping force of the tightening ring 5. Disassembly operation: When disassembly is required, reverse the limiting plate 32 to release the gripping push shaft 41, release the restriction on the flipping push plate 4, lift the gripping push shaft 41 to drive the flipping push plate 4 to reset, tighten the ring 5 to loosen the contraction part 12, smooth shaft 22 retracts to the inside of the movable port 11, the inner insertion tube 21 disengages from the feed tube, and the feed tube body 6 can be quickly pulled out.
