[0035] like Figure 1 The figure shows the installation structure diagram of the existing rapper. During use, the steel ball often hits the cylinder, causing damage and penetration of the cylinder, and serious wear of the guide tube. The service life is generally only 2-4 months. The entire cylinder can only be replaced each time, and the damaged cylinder needs to be repaired at the same time, which has a great impact on the life of the entire equipment and the inspection and maintenance time.

[0036] This article will explain the dryer drum vibrator of the pelletizing process in the steel industry. Figure 2 The figure shows the installation diagram of the existing rapper. During use, the steel ball continuously impacts the same point, causing perforation of the cylinder. The rapper must be replaced after only 6 months of use.

[0037] In order to solve the existing problems, ensure that the impact on the cylinder is reduced, extend the service life of the cylinder body, and reduce the maintenance intensity, the present invention provides an arc-shaped steel cylinder vibrator.

[0038] like Figure 3The figure shows the installation diagram of the vibrator of the present invention. The circular arc steel cylinder vibrator of the present invention is a vibrator installed on the cylinder of cylindrical rotating equipment in the metallurgical industry, including: arc plate 02, short tube 03, steel ball 07, guide tube 08, impact plate 09 and buffer device. The arc plate 02 is welded to the cylinder 01, the lower end of the short tube 03 is welded to the arc plate 02, and the upper end is detachably connected to the lower end of the guide tube 08; the impact plate 09 (vibrating circular steel plate) is placed in the short tube 03 and connected to the arc plate 02, and an activity space is formed between the impact plate 09 and the guide tube 08, and the steel ball 07 is placed in the activity space and moves in the activity space. The outer wall of the guide tube 08 is provided with a longitudinal rib plate 10 and an annular rib plate 11. The buffer device is installed at the end of the guide tube 08 ( Figure 3 The upper right end in this embodiment is based on Figure 3 The current location status is shown in .

[0039] Preferably, the longitudinal ribs 10 and the annular ribs 11 are welded to the outer wall of the guide tube 08, and a plurality of annular ribs 11 are provided, which are spaced apart along the length direction of the guide tube 08; a plurality of longitudinal ribs 10 are provided between two adjacent annular ribs 11, and the upper flange 06 of the guide tube 08 is connected to the adjacent annular ribs 11 ( Figure 3 A plurality of longitudinal ribs 10 are arranged between the annular ribs 11 at the bottom. Each group of longitudinal ribs 10 is evenly distributed along the outer wall of the guide tube 08.

[0040] When the cylinder 01 rotates, the steel ball 07 in the vibrator moves in the guide tube 08. When the cylinder 01 rotates to the highest point, the steel ball 07 falls and impacts the upper pad (impact plate 09) of the cylinder 01. After the cylinder 01 is vibrated, the material adhered to the inside of the cylinder 01 falls, thereby ensuring that there is no material accumulation inside the cylinder 01. When the pad is impacted and worn, the pad is replaced regularly. At the same time, a longitudinal rib plate 10 is set at every 60° interval along the 360° direction on the outer wall of the guide tube 08, and an annular rib plate 11 is set at intervals in the length direction, thereby effectively ensuring that the steel ball 07 will not fall off the guide tube 08, greatly extending the service life of the guide tube 08.

[0041] Preferably, the buffer device is mainly composed of a buffer shaft 12, a disc spring 13, an end plate 14 and its cover plate 15, and a nut 16. The end plate 14 is welded to the end of the guide tube 08 and the longitudinal rib plate 10, and the cover plate 15 is connected to the outer side of the end plate 14 by multiple sets of bolts. The buffer shaft 12 and the disc spring 13 are located inside the guide tube 08. The buffer shaft 12 is slidably connected to the cover plate 15 and can be reciprocatingly slidably connected in the guide tube 08. The disc spring 13 is sleeved on the outside of the buffer shaft 12, and the two ends of the disc spring 13 are fixedly connected to the buffer shaft 12 and the end plate 14 respectively. During operation, when the steel ball 07 is recalled after impact, the steel ball 07 falls back to the buffer shaft 12, and the buffer shaft 12 compresses the disc spring 13 to gradually reduce the speed of the steel ball 07. The disc spring 13 moves in the guide tube 08. When designed, the thickness of the end plate 14 is the maximum compression amount of the disc spring 13.

[0042] Preferably, the buffer shaft 12 is a stepped shaft, including a first shaft section, a second shaft section and a third shaft section connected in sequence, the outer diameter of the first shaft section is larger than the outer diameter of the second shaft section, and the outer diameter of the second shaft section is larger than the outer diameter of the third shaft section; a first through hole connected to the inside of the guide tube 08 is opened in the middle of the end plate 14, and a second through hole connected to the first through hole is opened in the middle of the cover plate 15, and the inner diameter of the second through hole is smaller than the inner diameter of the first through hole; the third shaft section is slidably connected in the second through hole, and one end of the third shaft section passing through the second through hole is matched with a nut 16, and the nut 16 is used to limit the movement of the buffer shaft 12; the second shaft section slides in the first through hole, and the disc spring 13 is sleeved on the outside of the second shaft section and is located between the first shaft section and the end plate 14; wherein one end of the disc spring 13 is connected to the first shaft section, and the other end is connected to the end plate 14. When the steel ball 07 impacts the buffer shaft 12, as Figure 4 The current schematic diagram shown will cause the buffer shaft 12 to move to the right, wherein the first shaft section compresses the disc spring 13, the second shaft section slides to the right in the first through hole, and the third shaft section slides to the right in the second through hole. When the steel ball 07 is separated from the buffer shaft 12, the buffer shaft 12 is reset under the action of the disc spring 13, and the first shaft section, the second shaft section, and the third shaft section all move to the left, and the leftward movement of the buffer shaft 12 is limited by the nut 16.

[0043] Preferably, the end plate 14 and the adjacent annular rib plate 11 ( Figure 3 A plurality of longitudinal ribs 10 are arranged between the uppermost annular ribs 11 , and the plurality of longitudinal ribs 10 are evenly distributed along the circumference of the outer wall of the guide tube 08 .

[0044] Preferably, flanges (short tube flange 04 and upper flange 06) are provided between the short tube 03 and the guide tube 08, and the short tube flange 04 and the upper flange 06 are detachably connected by bolts. The short tube flange 04 is provided at the upper end of the short tube 03, and the upper flange 06 is provided at the lower end of the guide tube 08. A pressure ring 05 is provided between the short tube flange 04 and the upper flange 06; the pressure ring 05 presses the impact plate 09 onto the arc plate 02, wherein the body of the pressure ring 05 is inserted into the short tube 03, the body end (lower end) of the pressure ring 05 is pressed against the upper end of the impact plate 09, and the lower end of the impact plate 09 is pressed and contacted with the arc plate 02. When designing, the diameter of the impact plate 09 is 10-15 mm smaller than the diameter of the short tube 03, so as to facilitate the effective removal of the impact plate 09 after impact. In addition, a longitudinal rib plate 10 and an annular rib plate 11 are provided on the guide tube 08; the service life of the guide tube 08 is greatly extended.

[0045] A novel rapper of the present invention can solve the following problems:

[0046] 1) The problem that the original steel ball directly impacts the cylinder steel plate, causing the cylinder steel plate to be damaged, is solved. The new rapper of the present invention has a rapping plate inside the rapper, that is, the impact plate 09 (impact pad) can be replaced, and the steel ball 07 directly impacts the rapping plate, and the rapping plate then transmits the vibration force to the cylinder 01. When the rapping plate is damaged by the impact of the steel ball 07, it can be replaced regularly, thereby solving the original overall replacement situation. After each impact of the steel ball 07, the force is transmitted to the cylinder 01, achieving the same vibration effect while effectively protecting the cylinder 01.

[0047] 2) The longitudinal ribs 10 and the annular ribs 11 are installed on the guide tube 08, which greatly prolongs the service life of the guide tube 08.

[0048] 3) A buffer device is provided at the end of the guide tube 08, which is mainly composed of a buffer shaft 12, a disc spring 13, an end plate 14 and its cover plate 15, and a nut 16. During operation, when the steel ball 07 returns after impact, the steel ball 07 falls back to the buffer shaft 12, and the buffer shaft 12 compresses the disc spring 13 to gradually reduce the speed of the steel ball 07. The disc spring 13 moves in the guide tube 08. When designed, the thickness of the end plate 14 is the maximum compression amount of the disc spring 13.

[0049] The circular arc steel drum vibrator of the present invention is an effective vibrating method for preventing materials from sticking on cylindrical mixers or dryers in the metallurgical field, and its vibrating strength is directly related to the length of the guide tube. In the past, the steel ball of the vibrator directly impacted the cylinder body, while the steel ball of the vibrator of the present invention impacts the replaceable impact plate, which effectively solves the problems of short service life, difficult replacement, and production impact.
