Description

Technical Field

[0001] This utility model relates to the field of fertilizer production equipment technology, and in particular to a vibration device for fertilizer granule drying equipment. Background Technology

[0002] In fertilizer production, the granulated fertilizer granules need to be dried using a drum dryer. To prevent the fertilizer granules from sticking to the inner wall of the drum, multiple vibrating devices are evenly distributed in a ring on the outer wall of the drum. The vibrating devices on existing drying equipment are the same as those disclosed in CN205027101U, combined with... Figure 1 The vibrating device consists of a hollow tube directly welded to the outer wall of the drum. However, after prolonged use, the following problems arise: First, the metal balls directly impact the outer wall of the drum. Since the drum's wall thickness is approximately 8mm, repeated impacts from the metal balls cause inward deformation at the impact points. Second, after prolonged use, wear on the inner wall of the hollow tube can lead to breakage. However, since the hollow tube is directly welded to the outer wall of the drum, it needs to be cut before repair or replacement. If it is welded to the original position, it needs to be ground smooth before welding again, making the replacement of the hollow tube inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the problems existing in the background art and provide a vibration device for fertilizer granule drying equipment. By setting a hammer plate, which is installed on a clamping plate, the hammer plate directly bears the impact of the hammer ball, reducing damage to the drum. The clamping plate is installed and connected to the drum, and the connecting ring is detachably connected to the clamping plate by screws, making the replacement of the guide tube more convenient.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a vibration device for fertilizer granule drying equipment, including a guide tube, a hammer ball movably placed inside the guide tube, one end of the guide tube being closed, and the other end being used for installation and connection with the drum of the drying equipment. A connecting ring is fixedly connected to the end of the guide tube that is installed with the drum, and the connecting ring is provided with a plurality of first mounting holes. It also includes a clamping plate and a hammer plate, and the clamping plate is provided with a plurality of second mounting holes, the second mounting holes corresponding to the positions of the first mounting holes. The hammer plate is installed on the clamping plate, and the connecting ring is detachably connected to the clamping plate by screws.

[0005] The edge of the hammer plate is provided with multiple lugs, and the middle of the side of the card plate facing the connecting ring is provided with a countersunk hole. The circumferential wall of the countersunk hole is provided with multiple slots axially, and the number of slots is the same as the number of lugs. The hammer plate is placed in the countersunk hole, and the lugs are placed in the slots.

[0006] The thickness of the lug is not less than the depth of the slot.

[0007] The bottom of the countersunk hole circumferential wall is provided with a slot on one side of the slot. The lug of the hammer plate can be screwed into the slot. Multiple limiting blocks are provided on the side of the connecting ring connected to the card plate. The number of limiting blocks is the same as the number of slots. The limiting blocks are inserted into the slots to limit the hammer plate.

[0008] The limiting block has a wedge-shaped structure.

[0009] The outer circumferential wall of the card plate is provided with multiple radial holes, which correspond to the card slots and are connected to each other.

[0010] It also includes a base plate with a fourth mounting hole, which is a threaded hole. One side of the base plate is an arc-shaped surface that fits the outer wall of the roller, and the other side is used to connect with the clamping plate.

[0011] The base plate is fixedly connected to the outer circumference of the roller with stiffening plates.

[0012] The present invention has the following beneficial effects:

[0013] 1. This utility model incorporates a hammering plate mounted on a clamping plate. The hammering plate directly bears the impact of the hammering ball, reducing damage to the roller. The connecting ring is detachably connected to the clamping plate via screws, making the replacement of the guide tube more convenient.

[0014] 2. This utility model features a slot at the bottom of the countersunk hole in the clamping plate. During installation, the lug of the hammer plate can be screwed into the slot, allowing the hammer plate to be embedded within the clamping plate. This prevents the hammer plate from contacting the connecting ring, reducing wear on the connecting ring. Four limiting blocks are provided on the side where the connecting ring connects to the clamping plate. These limiting blocks extend a certain distance and, during installation, insert into the slots to limit the hammer plate's movement, preventing it from rotating.

[0015] 3. The curved surface of the base plate of this utility model fits the outer wall of the roller, and the edge of the base plate is welded and fixed to the roller. The clamping plate is located between the connecting ring and the base plate. The threaded end of the screw passes through the first mounting hole on the connecting ring and the second mounting hole on the clamping plate, and then is screwed and fixed to the fourth mounting hole. This not only increases the force-bearing area of ​​the hammer ball impacting the roller, but also makes the clamping plate, hammer plate, and guide tube vulnerable parts that can be replaced individually as needed.

[0032] Example 1:

[0033] like Figure 2-7 As shown, a vibration device for a fertilizer granule drying equipment includes a guide tube 10, within which a hammer ball 50 is movably placed. One end of the guide tube 10 is closed, and the other end is used for installation and connection with a drum 1 of the drying equipment. A connecting ring 11 is fixedly connected to the end of the guide tube 10 that is installed with the drum 1, and the connecting ring 11 is provided with a plurality of first mounting holes 12. It also includes a clamping plate 20 and a hammering plate 30. The clamping plate 20 is provided with a plurality of second mounting holes 21, the second mounting holes 21 corresponding to the positions of the first mounting holes 12. The hammering plate 30 is mounted on the clamping plate 20, and the clamping plate 20 is installed and connected to the drum 1. The connecting ring 11 is detachably connected to the clamping plate 20 by screws 60.

[0034] The guide tube 10 can be a straight tube or a... Figure 2 , 3The diagram shows a tube with a bent section. The diameter of the hammer ball 50 is smaller than the inner diameter of the guide tube 10, allowing the hammer ball 50 to roll automatically within the guide tube 10. By providing a hammer plate 30, which is mounted on the clamping plate 20, the hammer plate 30 directly bears the impact of the hammer ball 50, reducing damage to the roller 1. In this embodiment, the clamping plate 20 is fixedly connected to the roller 1, and the connecting ring 11 is detachably connected to the clamping plate 20 by screws 60, making the replacement of the guide tube 10 more convenient.

[0035] In this embodiment, the edge of the hammer plate 30 is provided with four lugs 31, and the middle of the side of the card plate 20 facing the connecting ring 11 is provided with a countersunk hole 22. The circumferential wall of the countersunk hole 22 is provided with four slots 23. The number of slots 23 is the same as the number of lugs 31. The hammer plate 30 is placed in the countersunk hole 22, and the lugs 31 are placed in the slots 23.

[0036] In this embodiment, during installation, the clamping plate 20 is welded to the roller 1, the second mounting hole 21 is a threaded hole, the hammer plate 30 is placed into the countersunk hole 22, the lug 31 is placed into the slot 23, and the threaded end of the screw 60 passes through the first mounting hole 12 on the connecting ring 11 and is then screwed into the second mounting hole 21 for fixation. The connecting ring 11 limits the lug 31 within the slot 23.

[0037] In a preferred embodiment, the thickness of the lug 31 is not less than the depth of the slot 23. That is, the thickness of the lug 31 is equal to or greater than the depth of the slot 23, thus better securing the hammer plate 30.

[0038] Example 2:

[0039] Based on Example 1, see Figure 5 The bottom of the circumferential wall of the countersunk hole 22 is provided with a slot 24 on one side of the slot 23. The lug 31 of the hammer plate 30 can be screwed into the slot 24. Multiple limiting blocks 13 are provided on the side of the connecting ring 11 connected to the slot 20. The number of limiting blocks 13 is the same as the number of slots 23. The limiting blocks 13 are inserted into the slots 23 to limit the hammer plate 30.

[0040] By providing a slot 24 at the bottom of the countersunk hole 22 of the retaining plate 20, the lug 31 of the hammer plate 30 can be screwed into the slot 24 during installation, allowing the hammer plate 30 to be embedded in the retaining plate 20. The hammer plate 30 does not contact the connecting ring 11, reducing wear on the connecting ring 11 caused by the hammer plate 30. See also... Figure 4 Four limiting blocks 13 are provided on the side where the connecting ring 11 is connected to the card plate 20. The limiting blocks 13 extend a certain distance. During installation, the limiting blocks 13 are inserted into the slot 23 to limit the hammer plate 30 so that the hammer plate 30 cannot rotate.

[0041] Furthermore, to facilitate the insertion of the limiting block 13 into the slot 23, the limiting block 13 can adopt a wedge-shaped structure. That is, the end of the limiting block 13 away from the connecting ring 11 is narrower, and the end connected to the connecting ring 11 is wider. When the screw 60 is tightened, one side of the limiting block 13 tightly abuts against the lug 31. Of course, the side of the lug 31 that abuts against the limiting block 13 can also be set as an inclined surface adapted to the limiting block 13.

[0042] See Figure 5 The outer circumferential wall of the clamping plate 20 is provided with multiple radial holes 25, which correspond to the positions of the clamping grooves 24 and are connected to each other. The radial holes 25 serve two purposes: firstly, to facilitate the machining of the clamping grooves 24, during which the milling cutter mills the radial holes 25 and the clamping grooves 24 from the outer circumference of the clamping plate 20; secondly, to facilitate the removal of the hammer plate 30 from the countersunk hole 22 of the clamping plate 20. After the lug 31 is screwed into the clamping groove 24, the lug 31 can be moved through the radial holes 25.

[0043] It should be noted that in this embodiment, the position of the second mounting hole 21 should avoid the position of the slot 24.

[0044] Example 3:

[0045] Based on Example 1 or Example 2, see Figure 2 , 3 7. The present invention also includes a base plate 40, on which a fourth mounting hole 41 is provided. The fourth mounting hole 41 is a threaded hole. One side of the base plate 40 is an arc-shaped surface 42 adapted to the outer wall of the roller 1, and the other side is used to connect with the clamping plate 20.

[0046] In use, the arc-shaped surface 42 of the base plate 40 fits against the outer wall of the roller 1, and the edge of the base plate 40 is welded and fixed to the roller 1. The clamping plate 20 is located between the connecting ring 11 and the base plate 40. The threaded end of the screw 60 passes through the first mounting hole 12 on the connecting ring 11 and the second mounting hole 21 on the clamping plate 20, and then screws and fixes it to the fourth mounting hole 41. This structure not only increases the force-bearing area of ​​the hammer ball 50 impacting the roller 1, but also makes the clamping plate 20, the hammer plate 30, and the guide tube 10 vulnerable parts that can be replaced individually as needed.

[0047] Furthermore, a stiffening plate 43 is fixedly connected to the outer circumference of the base plate 40, and the stiffening plate 43 is used for welding to the outer wall of the roller 1. This increases the support area and makes the impact force more dispersed.

[0048] The operation process or principle of this utility model is as follows:

[0049] Based on Example 3, when using it, please refer to... Figure 2 , 3During installation, first, the arc-shaped surface 42 of the base plate 40 is attached to the outer wall of the roller 1, and the edge of the base plate 40 is welded and fixed to the roller 1. At the same time, the stiffening plate 43 is welded to the outer wall of the roller 1.

[0050] Next, place the hammer plate 30 into the countersunk hole 22, and the lug 31 into the slot 23. Then, screw the lug 31 into the retaining groove 24, so that the hammer plate 30 is embedded in the retaining plate 20. The hammer plate 30 does not contact the connecting ring 11, reducing the wear caused by the hammer plate 30 on the connecting ring 11. Then, align the connecting ring 11 at one end of the guide tube 10 with the retaining plate 20. Then, pass the threaded end of the screw 60 through the first mounting hole 12 on the connecting ring 11 and the second mounting hole 21 on the retaining plate 20, and then screw it into the fourth mounting hole 41 for fixation. During installation, apply thread-locking adhesive to the threads of the screw 60 to prevent the screw 60 from loosening due to vibration.

[0051] With the above structure, the hammer plate 30 directly bears the impact of the hammer ball 50, reducing damage to the roller 1. After the hammer plate 30 is damaged, it can be replaced separately. After the clamping plate 20 is worn, it can be replaced separately. After the guide tube 10 is worn and broken, it can be replaced.
