Description

Technical Field

[0001] This application relates to the field of granular antioxidant production, and particularly to a drip plate granulator. Background Art

[0002] In the production and molding process of granular antioxidants, drip plate granulators are often used. A drip plate granulator generally includes a feeder, a cooling conveyor steel belt, and a scraper. The feeder is located at one end of the cooling conveyor steel belt and above the cooling conveyor steel belt, and the scraper is located at the other end of the cooling conveyor steel belt and abuts against the outer side wall of the cooling conveyor steel belt.

[0003] During the working process, the feeder intermittently sprays liquid materials onto the cooling conveyor steel belt. The liquid materials contact the cooling conveyor steel belt and gradually solidify into particles. The cooling conveyor steel belt rotates continuously to convey the granular materials. When the granular materials reach the other end of the cooling conveyor steel belt, the scraper scrapes off the granular materials fixed on the cooling conveyor steel belt. The scraped granular materials fall along the side of the scraper away from the steel plate, thus completing granulation. However, the scraper usually generates some material powders during the process of scraping off the granular materials. Therefore, a number of sieve holes are usually provided on the scraper. During the process of the granular materials sliding along the scraper, the material powders can break away from the granular materials along the sieve holes.

[0004] However, the granular materials sprayed from the feeder onto the cooling conveyor steel belt are not regular enough after forming, and there may be protrusions or tips. During the process of the granular materials sliding along the scraper, some granular materials may be stuck with the sieve holes, resulting in the situation of sieve hole blockage. As the sieve hole blockage increases, the screening efficiency of the granular materials will be reduced. Summary of the Invention

[0005] In order to reduce the occurrence of sieve hole blockage, this application provides a drip plate granulator.

[0006] The drip plate granulator provided by this application adopts the following technical solutions:

[0007] A drip plate granulator includes an inclined scraper. One or more screening components are installed on the scraper. The scraper is provided with installation openings having the same number as the screening components. Each screening component is installed at the corresponding installation opening. The screening component includes an arc-shaped mesh plate and a scraping blade. The upper end of the arc-shaped mesh plate is hinged to the upper edge of the installation opening, and a first torsion spring is installed between the upper end of the arc-shaped mesh plate and the upper edge of the installation opening. The middle part of the arc-shaped mesh plate protrudes upward from the upper surface of the scraper. The upper end of the scraping blade abuts against the upper arc surface of the arc-shaped mesh plate. The lower end of the scraping blade is hinged to the lower edge of the installation opening, and a second torsion spring is installed between the lower end of the scraping blade and the lower edge of the installation opening. A control component is connected to the scraping blade to intermittently pull and release the scraping blade downward of the installation opening.

[0008] By adopting the above technical solution, when the granular material falls along the scraper, the granular material will accumulate at the position where the arc-shaped mesh plate protrudes from the upper surface of the scraper. At this time, the material powder mixed in the granular material passes through the arc-shaped mesh plate and falls. The granular material continues to accumulate at the arc-shaped mesh plate until part of the granular material slides down from the upper end of the arc-shaped mesh plate along the scraper and the scraper. The setting of the arc-shaped mesh plate facilitates the granular material accumulated at the protrusion of the arc-shaped mesh plate to fall over the arc-shaped mesh plate. And by intermittently pulling the scraper blade to move in the direction close to the bottom of the installation port through the control component, the arc-shaped mesh plate is also pushed to move in the direction close to the bottom of the installation port during the movement of the scraper blade. The movement of the arc-shaped mesh plate in the direction close to the installation port facilitates the unloading of the granular material accumulated at the arc-shaped mesh plate, and during the movement of the arc-shaped mesh plate, the scraper blade moves relative to the upper arc surface of the arc-shaped mesh plate, which is convenient for scraping the granular material attached to the arc-shaped mesh plate, thereby dredging the arc-shaped mesh plate, reducing the blockage of the screen mesh holes, and improving the screening efficiency of the granular material.

[0009] Preferably, the control assembly comprises a control motor installed on the lower side of the scraper, a wire wheel is fixedly connected to the output shaft of the control motor, and a control rope is fixedly connected between the wire wheel and the scraper.

[0010] By adopting the above technical solution, the control motor is intermittently turned on and off. When the control motor is started, the output shaft of the control motor drives the wire wheel to rotate, and the wire wheel rotates to reel the control rope. In this way, the control rope pulls the scraper to move in the direction close to the bottom of the installation port, and the movement of the scraper pushes the arc-shaped mesh plate to move. When the control motor is turned off, the arc-shaped mesh plate is reset by the force of the first torsion spring, and the scraper is reset by the force of the second torsion spring.

[0011] Preferably, the scraper is connected to an adjustment component for adjusting the inclination of the scraper, a mounting frame is provided under the scraper, an arc rod is fixedly connected to the lower surface of the scraper, the middle part of the arc rod gradually protrudes downward, the arc rod passes through the mounting frame and is slidably connected to the mounting frame, and a fastener is connected to the mounting frame to lock the arc rod and the mounting frame.

[0012] By adopting the above technical solution, the fasteners are loosened to allow the arc rod to move relative to the mounting frame, and then the arc rod is rotated. The rotation of the arc rod can adjust the inclination angle of the scraper, and the operation is simple and convenient.

[0013] Preferably, the mounting frame includes a first frame rod and a second frame rod, a side surface of the first frame rod and a side surface of the second frame rod are both provided with through holes, the arc rod passes through the through holes on the first frame rod and the second frame rod, the inner circle side wall of the arc rod is provided with a plurality of convex teeth, each through hole is rotatably connected to a gear, and each gear is engaged with the convex teeth.

[0014] By adopting the above technical solution, when the arc rod is rotated, the movement of the arc rod and the rotation of the gear cooperate with each other, and the rotation of the gear provides a guide for the movement of the arc rod.

[0015] Preferably, the fastener includes a bolt rotatably connected to the first rack. The bolt passes through the first rack and the gear on the first rack, and is fixedly connected to the gear on the first rack. One end of the bolt is threadedly connected to a nut that abuts against one side wall of the first rack.

[0016] By adopting the above technical solution, rotate the nut on the bolt to disengage the nut from the first rack. Then rotate the bolt, and the rotation of the bolt can drive the gear on the first rack to rotate, and the rotation of the gear can drive the arc rod to rotate, so as to facilitate the adjustment of the inclination of the scraper, and further adjust the feeding rate of the granular material.

[0017] Preferably, a cooling conveyor steel belt is provided on one side of the scraper. The cooling conveyor steel belt includes a steel belt body and a support frame. The upper end of the scraper abuts against the outer surface of one end of the steel belt body. The mounting frame is fixedly connected with a screw rod in the direction close to the support frame. The screw rod passes through the support frame, and two nuts for clamping the support frame are threadedly connected to the screw rod.

[0018] By adopting the above technical solution, loosen the nut on the screw rod to move the nut away from the support frame. Then the mounting frame and the scraper on the mounting frame can be moved away from or close to the cooling conveyor steel belt, which is convenient for adjusting the tightness of the scraper against the cooling conveyor steel belt.

[0019] Preferably, a guide plate is fixedly connected to the lower surface of the scraper. The guide plate has the same inclination direction as the scraper and is located below the installation opening.

[0020] By adopting the above technical solution, the guide plate receives the material powder falling from the installation opening and plays a guiding role in the sliding of the material powder.

[0021] Preferably, the end of the scraping blade that abuts against the upper arc surface of the arc-shaped mesh plate is shrunk into a tip, and the tip abuts against the upper arc surface of the arc-shaped mesh plate.

[0022] By adopting the above technical solution, the tip of the scraping blade abuts against the upper arc surface of the arc-shaped mesh plate, which is convenient for the particles accumulated on the arc-shaped mesh plate to move over the arc-shaped mesh plate to the scraping blade.

Detailed implementation manners

[0033] The following further describes the present application in detail with reference to the attached Figures 1-5 drawings.

[0034] The embodiment of the present application discloses a drip plate granulator. Refer to Figure 1 , a drip plate granulator includes a cooling conveyor steel belt 1, and a scraping mechanism 2 is connected to one end of the cooling conveyor steel belt 1. The scraping mechanism 2 is used for scraping the granular materials on the cooling conveyor steel belt 1.

[0035] The cooling conveyor steel belt 1 includes a steel belt body 11 in a closed-loop shape, and also includes a support frame 12 and two support rollers 13. The steel belt body 11 is installed outside the two support rollers 13. A mounting roller 14 is rotatably connected to the axis of each support roller 13. The mounting roller 14 penetrates through the support roller 13, and each end of the mounting roller 14 is fixedly connected to the support frame 12.

[0036] Refer to Figure 2, the scraping mechanism 2 includes a scraper 21 and a mounting frame 22, and the mounting frame 22 is used to support the scraper 21. One end of the scraper 21 abuts against the outer side wall of the steel belt body 11, and the scraper 21 gradually slopes downward in the direction away from the steel belt body 11. One or more screening components 23 are installed on the scraper 21. In this embodiment, one screening component 23 is installed on the scraper 21, and the screening component 23 is used to screen the material powder mixed in the granular material.

[0037] Refer to Figure 2 and Figure 3 , the scraper 21 is provided with mounting openings 211 having the same number as the screening components 23. The screening component 23 includes an arc-shaped mesh plate 231 and a scraping blade 232, and the middle part of the arc-shaped mesh plate 231 gradually bulges upward. The upper end of the arc-shaped mesh plate 231 is fixedly connected with a connecting shaft 233, and the connecting shaft 233 is as long as the arc-shaped mesh plate 231. The connecting shaft 233 penetrates through the arc-shaped mesh plate 231 and each end of the connecting shaft 233 is rotatably connected with one side wall of the mounting opening 211. Both ends of the connecting shaft 233 are sleeved with first torsion springs 234. One end of the first torsion spring 234 is fixedly connected with the corresponding side wall of the mounting opening 211, and the other end is fixedly connected with the arc-shaped mesh plate 231. When the first torsion spring 234 is in a normal state, the middle part of the arc-shaped mesh plate 231 protrudes from the upper surface of the scraper 21.

[0038] The upper end of the scraping blade 232 shrinks into a tip and abuts against the upper surface of the arc-shaped mesh plate 231. The lower end of the scraping blade 232 is fixedly connected with a rotating shaft 235, and the scraping blade 232 is as long as the arc-shaped mesh plate 231. The rotating shaft 235 penetrates through the scraping blade 232 and each end of the rotating shaft 235 is rotatably connected with one side wall of the mounting opening 211. Both ends of the rotating shaft 235 are sleeved with second torsion springs 236. One end of the second torsion spring 236 is fixedly connected with one side wall of the mounting opening 211, and the other end is fixedly connected with the scraper 21. The scraping blade 232 gradually slopes downward in the direction away from the arc-shaped mesh plate 231, and a control component 24 is connected to the scraping blade 232 to intermittently pull and release the scraping blade 232 downward below the mounting opening 211.

[0039] When the cooling conveyor steel belt 1 rotates, the granular material on the cooling conveyor steel belt 1 is scraped off by the scraper 21 and slides down along the scraper 21. The granular material sliding along the scraper 21 is blocked by the arc-shaped mesh plate 231 and accumulates on one side of the arc-shaped mesh plate 231 close to the cooling conveyor steel belt 1. At this time, the material powder mixed in the granular material passes through the arc-shaped mesh plate 231 and falls, completing the screening of the granular material.

[0040] When there is a large accumulation of granular materials at the arc-shaped mesh plate 231, some of the granular materials that have completed screening and are accumulated at the top of the arc-shaped mesh plate 231 cross over the arc-shaped mesh plate 231 and continue to slide down along the scraping blade 232 and the scraping plate 21, and then move to other positions for collection. The design of the arc-shaped mesh plate 231 facilitates the sliding of granular materials along the arc surface of the arc-shaped mesh plate 231.

[0041] At the same time, the control component 24 is activated to intermittently pull the scraping plate 21 downward below the installation port 211. The scraping blade 232 is forced to rotate in the direction close to the installation port 211, and the arc-shaped mesh plate 231 also rotates in the direction close to the installation port 211 under the action of the scraping blade 232 until the upper surface of the scraping blade 232 approaches parallel to the upper surface of the scraping plate 21. At this time, the surface of the arc-shaped mesh plate 231 exposed above the scraping blade 232 also approaches parallel to the upper surface of the scraping plate 21. In this way, the granular materials remaining at the arc-shaped mesh plate 231 can slide more smoothly. Moreover, during the movement of the arc-shaped mesh plate 231, the relative movement of the scraping blade 232 with respect to the arc-shaped mesh plate 231 also facilitates scraping the granular materials attached to the arc-shaped mesh plate 231, and the granular materials blocking the arc-shaped mesh plate 231 can also be easily separated from the arc-shaped mesh plate 231.

[0042] Refer to Figure 4 , a guide plate 3 is fixedly connected to the lower surface of the scraping plate 21. The guide plate 3 is located below the installation port 211 and gradually slopes downward in the direction away from the steel belt body 11. When the material powder falls from the installation port 211, the guide plate 3 provides a guiding effect for the movement of the material powder.

[0043] The control component 24 includes two fixing plates 241 fixedly connected to the side of the guide plate 3 facing away from the scraping plate 21. A wire wheel 242 is rotatably connected between the two fixing plates 241. A control motor 243 is also fixedly connected to the side of the guide plate 3 facing away from the scraping plate 21. The output shaft of the control motor 243 penetrates through one of the fixing plates 241 and is fixedly connected to the wire wheel 242. The control component 24 further includes a control rope 244. One end of the control rope 244 is fixedly connected to the side wall of the wire wheel 242, and the other end penetrates through the guide plate 3 and is fixedly connected to the lower surface of the scraping blade 232.

[0044] Refer to Figure 3 and Figure 4 , when the control motor 243 is started, the output shaft of the control motor 243 rotates to drive the wire wheel 242 to rotate. The wire wheel 242 rotates to wind up the control rope 244, and the control rope 244 is wound up to pull the scraping blade 232 to rotate in the direction close to the installation port 211. When the control motor 243 is turned off, at this time, the scraping blade 232 is reset under the action of the second torsion spring 236, and the arc-shaped mesh plate 231 is reset under the action of the first torsion spring 234. In this way, the control motor 243 can be intermittently turned on and off to pull the scraping plate 21 to move.

[0045] To facilitate the adjustment of the inclination of the scraping plate 21 and thus adjust the feeding rate of the granular material, an adjustment assembly 4 is connected to the scraping plate 21.

[0046] Referring to Figure 2 and Figure 5 , the mounting frame 22 includes two groups of seat frames, and the scraping plate 21 is located between the two groups of seat frames. Each group of seat frames includes a first rack bar 221 and a second rack bar 222, and a reinforcing bar 223 is fixedly connected between the first rack bar 221 and the second rack bar 222. The adjustment assembly 4 includes two arc-shaped bars 41, and each arc-shaped bar 41 is located at one end under the scraping plate 21. Both ends of each arc-shaped bar 41 are fixedly connected to the lower surface of the scraping plate 21. Through holes 224 are formed in one side surface of each of the first rack bar 221 and the second rack bar 222. The arc-shaped bar 41 passes through the through holes 224 in the first rack bar 221 and the second rack bar 222 and is lapped on the bottom surface of the through holes 224, and the seat frame supports the arc-shaped bar 41.

[0047] A gear 42 is rotatably connected in each through hole 224. A plurality of convex teeth 43 are provided on the inner sidewall of the arc-shaped bar 41, and the convex teeth 43 on each arc-shaped bar 41 are engaged with the corresponding two gears 42. A fastener for fixing the gear 42 to the first rack bar 221 is connected to the first rack bar 221. The fastener includes a bolt 44 rotatably connected to the first rack bar 221. The bolt 44 passes through the first rack bar 221 and the gear 42 on the first rack bar 221, and the bolt 44 is fixedly connected to the gear 42 on the first rack bar 221. A nut is threadedly connected to one end of the bolt 44 and abuts against one sidewall of the first rack bar 221.

[0048] When the nut abuts against one sidewall of the first rack bar 221, it is difficult for the bolt 44 to rotate. At this time, it is difficult for the gear 42 on the first rack bar 221 to rotate, that is, the arc-shaped bar 41 is locked, and the inclination of the scraping plate 21 is fixed. When it is necessary to adjust the inclination of the scraping plate 21, loosen the nuts on each first rack bar 221 to make the bolt 44 rotatable. At this time, synchronously rotate the two bolts 44 to adjust the rotation of the gear 42 on the first rack bar 221. The rotation of the gear 42 on the first rack bar 221 drives the arc-shaped bar 41 to rotate, so that the inclination of the scraping plate 21 can be adjusted. The gear 42 on the second rack bar 222 plays a guiding role in the movement of the arc-shaped bar 41.

[0049] Referring to Figure 2 , to facilitate the adjustment of the tightness of the scraping plate 21 against the cooling conveyor steel belt 1, a connection assembly 5 is connected to the mounting frame 22. The connection assembly 5 includes a screw rod 51 fixedly connected to each group of seat frames. The screw rod 51 is located on the side of the seat frame close to the support frame 12. Each screw rod 51 penetrates through the support frame 12, and two nuts are threadedly connected to the screw rod 51, and the two nuts clamp the support frame 12.

[0050] When it is necessary to adjust the distance between the scraping plate 21 and the cooling conveyor steel belt 1, loosen the nut on the screw rod 51 to move the nut away from the support frame 12, and then the mounting frame 22 and the scraping plate 21 on the mounting frame 22 can be moved in the direction close to or away from the cooling conveyor steel belt 1.

[0051] The implementation principle of the drip plate granulator in the embodiment of the present application is as follows: the cooling conveyor steel belt 1 rotates, and at the same time, the scraping plate 21 closely adheres to the outer side of one end of the cooling conveyor steel belt 1. The cooling conveyor steel belt 1 moves relative to the scraping plate 21. In this way, the scraping plate 21 scrapes the granular materials fixed on the surface of the cooling conveyor steel belt 1, and the scraped materials slide down along the scraping plate 21. Subsequently, the granular materials are blocked by the arc-shaped mesh plate 231 and accumulate on the side of the arc-shaped mesh plate 231 close to the cooling conveyor steel belt 1. The material powder mixed in the granular materials passes through the arc-shaped mesh plate 231 and slides down along the guide plate 3.

[0052] At the same time, the control motor 243 is intermittently opened and closed. The control motor 243 pulls the scraping plate 21 downward through the control rope 244 to the lower part of the mounting port 211. Subsequently, the scraping blade 232 and the arc-shaped mesh plate 231 are forced to rotate in the direction close to the mounting port 211 until the upper surface of the scraping blade 232 approaches parallel to the upper surface of the scraping plate 21. When the control motor 243 is closed, the scraping blade 232 is reset by the acting force of the second torsion spring 236, and the arc-shaped mesh plate 231 is reset by the acting force of the first torsion spring 234. In this way, the scraping blade 232 and the arc-shaped mesh plate 231 reciprocate.

[0053] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
