Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of granulating equipment, and in particular, to a locking structure of a granulator. BACKGROUND

[0002] In the pharmaceutical, chemical and other industries, the fluidized bed granulation dryer is widely used in the process of material granulation and drying. Among them, the top dust removal assembly is an important part of the fluidized bed granulation dryer. In the running process of the machine, in order to effectively remove the particles attached to the surface of the top dust removal assembly, this part needs to be vibrated up and down periodically. However, the existing technology currently faces many problems in realizing this vibration action. Because the vibration action state is relatively complex, the control of the frequency, amplitude and time of the vibration is not accurate enough, resulting in low vibration efficiency, which cannot fully shake off the particles on the surface, affecting the dust removal effect and the subsequent production quality. At the same time, after stopping the vibration, the stability of the top dust removal assembly is also difficult to guarantee. Due to the lack of effective locking structure or the locking structure is not perfect enough, it may cause residual vibration or position deviation of the assembly after stopping the vibration, which not only affects the normal operation of the equipment, but also increases the wear and failure risk of the equipment, shortens the service life of the equipment, and increases the maintenance cost. CONTENT OF THE UTILITY MODEL

[0003] In order to overcome the above defects, the embodiments of the present disclosure provide a locking structure of a granulator, which solves the technical problem of weak periodic vibration effect of the top dust removal assembly of the fluidized bed granulation dryer in the related art.

[0016] A clamping member is arranged to slide in the guide groove. The clamping member has an arc-shaped clamping portion. After the clamping member is driven by the pushing rod to move up and down, the arc-shaped clamping portion enters or exits the annular clamping groove.

[0017] For example, the granulator locking structure provided by at least one embodiment of the present disclosure further includes:

[0018] A second elastic member is arranged to act on one end of the clamping member and the other end of the inner wall of the guide groove, thereby providing a force for the clamping member to move away from the inner wall of the guide groove.

[0019] For example, the granulator locking structure provided by at least one embodiment of the present disclosure includes a plurality of guide grooves in the circumferential direction of the clamping bracket, and a plurality of clamping members and a plurality of second elastic members are arranged in the guide grooves.

[0020] For example, the granulator locking structure provided by at least one embodiment of the present disclosure includes an expanded-diameter accommodating cavity at one end of the pushing rod, and an expanded-diameter clamping portion at one end of the dust removal member. The expanded-diameter clamping portion is arranged to rotate in the expanded-diameter accommodating cavity, and the two ends of the first elastic member act on the inner wall of the expanded-diameter accommodating cavity and the expanded-diameter clamping portion, respectively.

[0021] For example, at least one embodiment of this disclosure provides a granulator locking structure in which the arc-shaped locking part has a second guide slope, the side wall of the annular locking groove has a third guide slope, and the second guide slope is configured to slide and abut against or cancel abut against the third guide slope after being driven to rise and slide.

First, the simultaneous lifting, vibration, and rotation of the dust collector significantly increases the cleaning range and effectiveness, greatly improving vibration efficiency and ensuring more thorough particle removal. Second, the guide slide and positioning frame provide precise tracks and stable support for the complex movements of the dust collector, ensuring accuracy and continuity of action and reducing the risk of poor cleaning results and equipment damage due to unstable movements. Furthermore, this combined action allows the equipment to complete effective dust removal in a shorter time, improving production efficiency and reducing the production cycle. Finally, this unique design better adapts to the complex working environment and demanding dust removal requirements of the top dust collector assembly in a fluidized bed granulator dryer, enhancing the overall performance and reliability of the granulator.

DETAILED DESCRIPTION

[0031] The present disclosure will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.

[0032] In order to make the drawing simple, only the parts related to the disclosure are schematically shown in each drawing, which does not represent the actual structure of the product.

For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0034] In the present disclosure, unless otherwise explicitly specified and limited, the "upper" or "lower" of the first feature to the second feature can include the direct contact of the first and second features, or the contact of the first and second features through another feature between them. Moreover, the "upper", "upper" and "upper" of the first feature to the second feature include the vertical and inclined upward of the first feature to the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0036] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-4 As shown, a granulator locking structure according to an embodiment of the present disclosure is illustrated. The granulator locking structure includes a main body 1, which has a granulation chamber 101, a dust removal chamber 102, and a guide slide 103, which are sequentially connected. A positioning frame 3 is disposed at one end of the guide slide 103 and has a connecting port 301 for connecting the dust removal chamber 102 and the guide slide 103. A dust removal component 2 is rotatably and vertically moved on the positioning frame 3 and is located inside the dust removal chamber 102.

[0038] In this embodiment, during operation, the driving device acts on the dust collector 2, enabling it to move up and down along the guide slide 103. Simultaneously, due to its cooperation with the positioning frame 3, it rotates during this movement. This combined action of lifting vibration and rotation effectively cleans the surface of the dust collector 2, removing attached particles. First, the simultaneous lifting vibration and rotation of the dust collector 2 significantly increases the cleaning range and effectiveness, greatly improving vibration efficiency and ensuring more thorough particle removal. Second, the guide slide 103 and positioning frame 3 provide precise tracks and stable support for the complex movements of the dust collector 2, ensuring accuracy and continuity of action and reducing the risk of poor cleaning results and equipment damage due to unstable movements. Furthermore, this combined action allows the equipment to complete effective dust removal in a shorter time, improving production efficiency and reducing the production cycle. Finally, this unique design better adapts to the complex working environment and demanding dust removal requirements of the top dust collector assembly of the fluidized bed granulator dryer, enhancing the overall performance and reliability of the granulator.

[0039] In some examples, a push rod 4 is also included, which is movable in the guide slide 103. One end of the dust removal component 2 is rotatably mounted on the push rod 4. The dust removal component 2 has a pushed inclined surface 201, and the positioning frame 3 has a pushing part 302. The dust removal component 2 is configured such that after it is lifted and slid, the pushed inclined surface 201 slides against the pushing part 302, thereby driving the dust removal component 2 to rotate.

[0040] In this embodiment, the push rod 4 moves up and down along the guide slide 103, driving the dust removal part 2 to move up and down. In the process of moving up and down, the pushed inclined surface 201 slides against the pushing part 302. Due to the blocking of the pushing part 302 and the guiding effect of the inclined surface, the dust removal part 2 is forced to rotate. First, through the cooperation of the push rod 4, the pushed inclined surface 201 and the pushing part 302, the rotation of the dust removal part 2 is achieved while moving up and down, which is simple in structure and stable and reliable in action. Second, the cooperation of this mechanical structure does not require complex control program, which reduces the cost and maintenance difficulty of the equipment, and improves the work efficiency. Third, the lifting and rotating amplitude and frequency of the dust removal part 2 can be accurately controlled, so as to better adapt to different working conditions and particle attachment conditions, and improve the stability and consistency of the dust removal effect. Finally, the simple and effective structure design prolongs the service life of the equipment, reduces the possibility of failure, and ensures the continuous and stable operation of the granulator.

[0041] In some examples, the pushed inclined surface 201 and the pushing part 302 are both several, and are arranged in a circle around the rotating shaft of the dust removal part 2.

[0042] In this embodiment, when the push rod 4 drives the dust removal part 2 to move up and down, the plurality of pushed inclined surfaces 201 will slide against the plurality of pushing parts 302 in turn. Due to the design of the circular arrangement, the dust removal part 2 can continuously and uniformly receive the driving force of rotation during the lifting process, so as to realize stable and continuous rotation. First, the circular arrangement of the plurality of pushed inclined surfaces 201 and the pushing part 302 ensures the continuity and stability of the rotation of the dust removal part 2 during the lifting process, avoids the jamming and unevenness of the rotation, and improves the dust removal effect. Second, the uniformly distributed structure can balance the stress, reduce local wear and stress concentration, and prolong the service life of the parts. Third, the circular arrangement design makes the control of the rotation of the dust removal part 2 more accurate and predictable, which helps to optimize the parameter setting of the whole dust removal process.

[0043] In some examples, a first elastic member 5 is further included, one end of the first elastic member 5 acting on the push rod 4, and the other end acting on the dust removal part 2, providing a force for resetting the rotation of the dust removal part 2.

[0044] In this embodiment, the first elastic member 5 is a torsion spring. When the push rod 4 drives the dust removal member 2 to lift and rotate, the first elastic member 5 is in a stretched or compressed state. When the driving force of the push rod 4 disappears, the first elastic member 5 releases the elastic potential energy to provide a rotating reset force for the dust removal member 2, so that the dust removal member 2 returns to the initial position. First, the first elastic member 5 can ensure that the dust removal member 2 resets accurately and quickly after completing the work action, and prepares for the next work cycle, thereby improving the work efficiency. Second, the elastic reset can reduce mechanical impact and wear, thereby prolonging the service life of the push rod 4 and the dust removal member 2 and other components. Third, it helps to maintain the stability and reliability of the equipment, and avoids affecting the subsequent work process due to the failure of the dust removal member 2 to reset in time.

[0045] In some examples, the guide chute 103 is cylindrical, and the inner wall of the guide chute 103 has an annular clamping groove 104. The device further comprises a clamping bracket 6 provided on the dust removal member 2, and the clamping bracket 6 has a guide groove 601 in the radial direction of the guide chute 103. A clamping member 7 is slidingly arranged in the guide groove 601, and the clamping member 7 has an arc-shaped clamping portion 701. The clamping member 7 is configured to, after being lifted and slidingly driven by the push rod 4, enter or exit the annular clamping groove 104 through the arc-shaped clamping portion 701.

[0046] In this embodiment, when the push rod 4 drives the dust removal member 2 to lift and slide, the clamping member 7 also lifts and slides. When the clamping member 7 rises to a certain position, the arc-shaped clamping portion 701 enters the annular clamping groove 104 to achieve locking. When the clamping member 7 descends, the arc-shaped clamping portion 701 exits the annular clamping groove 104 to release the locking. First, through the cooperation of the clamping member 7 and the annular clamping groove 104, the dust removal member 2 can be reliably locked when needed, ensuring its stability at a specific position and improving the work accuracy. Second, this locking structure responds quickly and is easy to operate, and can automatically achieve locking and unlocking according to the action of the push rod 4, thereby improving the automation degree and work efficiency of the equipment. The cooperation between the arc-shaped clamping portion 701 and the annular clamping groove 104 has high precision and small wear, can work stably for a long time, and reduces the maintenance cost.

[0047] In some examples, a second elastic member 8 is further included, one end of the second elastic member 8 acting on the clamping member 7, and the other end acting on the inner wall of the guide groove 601 to provide a force for the clamping member 7 to move away from the inner wall of the guide groove 601.

[0048] When the push rod 4 drives the clamping piece 7 to ascend and the arc-shaped clamping part 701 enters the annular clamping groove 104, the second elastic member 8 is in a compressed state, which increases the clamping force of the clamping piece 7 and the annular clamping groove 104 and ensures the reliability of the locking. When the push rod 4 drives the clamping piece 7 to descend and the arc-shaped clamping part 701 leaves the annular clamping groove 104, the second elastic member 8 is stretched, which helps the clamping piece 7 to reset. First, the second elastic member 8 enhances the stability of the clamping piece 7 and the annular clamping groove 104 when they are clamped, effectively prevents accidental unlocking, and improves the reliability of the locking. Second, the second elastic member 8 helps the clamping piece 7 to quickly reset during the unlocking process, which improves the operating efficiency of the device. Third, the existence of the elastic force reduces the rigid collision and wear between the clamping piece 7 and the inner wall of the guide groove 601, prolonging the service life of the components. Finally, the setting of the second elastic member 8 increases the self-adaptability of the entire locking structure, which can compensate for manufacturing and assembly errors to a certain extent and ensure the normal implementation of the locking function.

[0049] In some examples, the clamping bracket 6 has a plurality of guide grooves 601 circumferentially, and the clamping piece 7 and the second elastic member 8 are both a plurality of pieces, which are arranged in the guide grooves 601.

[0050] In this embodiment, when the push rod 4 drives the dust removal piece 2 to ascend and descend, the plurality of clamping pieces 7 ascend and descend simultaneously. During the ascending process, the arc-shaped clamping parts 701 of the plurality of clamping pieces 7 enter the annular clamping grooves 104 simultaneously, achieving multi-point synchronous locking. During the descending process, the arc-shaped clamping parts 701 leave the annular clamping grooves 104 simultaneously, releasing the locking. The clamping pieces 7 and the second elastic members 8 in the plurality of guide grooves 601 work cooperatively, achieving multi-point locking, which greatly improves the stability and reliability of the locking and ensures the accurate fixation of the dust removal piece 2 in the working position. Second, the evenly distributed multi-point locking structure can more evenly share the stress during locking, reducing local stress concentration and prolonging the service life of the components. Third, the plurality of clamping pieces 7 act simultaneously, improving the efficiency of locking and unlocking and enabling the device to switch working states faster. This circumferentially distributed multi-point locking structure design is more compact, occupies less space, and also enhances the versatility and adaptability of the entire granulator locking structure, which can meet different working conditions and requirements.

[0051] In some examples, one end of the push rod 4 has a diameter-expanded accommodating cavity 401, one end of the dust removal piece 2 has a diameter-expanded clamping part 202, the diameter-expanded clamping part 202 is rotationally arranged in the diameter-expanded accommodating cavity 401, and the two ends of the first elastic member 5 act on the inner wall of the diameter-expanded accommodating cavity 401 and the diameter-expanded clamping part 202, respectively.

[0052] In this embodiment, when the push rod 4 is lifted, the diameter-expanding clamping part 202 is rotated in the diameter-expanding accommodating cavity 401, so that the dust removal part 2 is lifted and rotated. In the process of rotation, the first elastic part 5 is correspondingly stretched or compressed. When the driving force of the push rod 4 disappears, the elastic restoring force of the first elastic part 5 makes the diameter-expanding clamping part 202 drive the dust removal part 2 to rotate back to the original position. The matching structure of the diameter-expanding accommodating cavity 401 and the diameter-expanding clamping part 202 is simple and stable, which can effectively realize the rotation connection and power transmission between the dust removal part 2 and the push rod 4. Secondly, this structure design provides a suitable installation position for the first elastic part 5, which ensures that the elastic part can stably play a role and realize reliable resetting of the dust removal part 2. In addition, the contact area and connection strength between the components are increased, the damage risk caused by stress concentration at the connection position is reduced, and the overall durability of the equipment is improved.

[0053] In some examples, the arc-shaped clamping part 701 has a second guide slope 702, and the sidewall of the annular clamping groove 104 has a third guide slope 105, the second guide slope 702 is configured to be brought into sliding abutment or non-abutment with the third guide slope 105 after being lifted and slid.

[0054] In this embodiment, when the push rod 4 drives the clamping part 7 to rise, the second guide slope 702 of the arc-shaped clamping part 701 is in sliding abutment with the third guide slope 105 of the sidewall of the annular clamping groove 104. In this process, due to the effect of the guide slope, the clamping part 7 can more smoothly enter the annular clamping groove 104, and the locking is realized. When the push rod 4 drives the clamping part 7 to descend, the second guide slope 702 and the third guide slope 105 are out of abutment, and the clamping part 7 can smoothly escape from the annular clamping groove 104, and the locking is released. First, the cooperation of the second guide slope 702 and the third guide slope 105 makes the clamping part 7 enter and exit the annular clamping groove 104 more smoothly and stably, reduces the jamming and impact, and improves the reliability of the locking and unlocking action. Secondly, the design of the guide slope reduces the wear between the components, prolongs the service life of the clamping part 7 and the annular clamping groove 104. Furthermore, it helps to improve the response speed of locking and unlocking, so that the granulator can switch between working states more quickly and improve the work efficiency.

[0055] In some examples, the dust removal part 2 has a plurality of dust removal cloth bags 203, and the plurality of dust removal cloth bags 203 are located in the dust removal cavity 102.

[0056] In the embodiment, during the operation, the dust removal cloth bag 203 is continuously moved by the lifting vibration and rotation of the dust removal member 2, so that the particles attached to the surface of the dust removal cloth bag 203 are removed by the vibration and centrifugal force. The composite action of the dust removal member 2 can effectively remove the particles on the surface of the dust removal cloth bag 203, maintain the good air permeability and filtering effect, and thus improve the overall dust removal efficiency. The cleaning method for the dust removal cloth bag 203 does not require additional cleaning devices or complex operations, thereby saving the cost and maintenance workload.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, not to limit the present disclosure. Although the present disclosure has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present disclosure can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present disclosure, which should be covered in the scope of the claims of the present disclosure.
