Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of granulation devices, and specifically relates to a granulation device for processing zirconium silicate ceramic sandblasting beads. Background Art
[0002] Zirconium silicate ceramic blasting beads are typically made from zirconium silicate and are available in various sizes and shapes to meet diverse grinding and polishing needs. They are typically fed into a pot-type granulator, where powdered zirconium silicate and a fixed amount of water are continuously rotated to form finely rounded particles. These particles are then removed and placed in a furnace for high-temperature sintering to set their shape.
[0003] Traditional pot-type pellet mills place a curved drum at an angle on a bridge. A reduction motor drives the main shaft, which passes through the bridge and rotates the drum. This causes the particles to rotate and spin within the drum, creating friction and roundness. After the particles are formed, the reduction motor is stopped, and the drum discharge door is moved to the bottom and opened to discharge the particles.
[0004] When processing zirconium silicate ceramic sandblasting beads in an existing pot-type granulator, a magnet is used to hold the lid tightly at the opening of the barrel, and the process of opening the lid again when adding materials is cumbersome. A rotating device is added between the lid and the barrel opening so that the feeding tube can pass through the lid to add materials while closing the opening. However, the device is far away from the reduction motor, and the radial load applied to the main shaft is large, causing loud noise during the granulation process. Therefore, we propose a granulation equipment for processing zirconium silicate ceramic sandblasting beads. Utility Model Content
[0005] The purpose of this utility model is to provide a granulation equipment for processing zirconium silicate ceramic sandblasting beads, which can form an air spring at the opening of the rotating pot body for buffering, relieve the radial load of the main shaft of the transmission mechanism, and help reduce the noise during the granulation process.
[0006] The technical solutions adopted in this application are as follows:
[0007] A granulating device for processing zirconium silicate ceramic sandblasting beads comprises a rotating pot body and a cover plugged into the opening of the rotating pot body, a feed pipe is fixed through the cover, the diameter of the cover is smaller than the diameter of the opening of the rotating pot body, an air bag with an annular structure and a guide ring fixedly connected to the inner side of the air bag are rotatably mounted on the inner edge of the cover, the outer edge of the guide ring is folded along the outer side of the air bag toward the inner side of the rotating pot body, an air intake pipe is fixed to the air bag, and the air intake end of the air intake pipe extends out of the opening of the rotating pot body. When processing zirconium silicate ceramic sandblasting beads, the cover is moved to drive the lower end of the feed pipe to be inserted into the interior of the rotating pot body until the cover covers the opening of the rotating pot body, and then the cover is opened. Open the air inlet pipe and use an air pump to inflate the inside of the airbag to expand and extend the airbag, and use the guide ring to support and guide the airbag so that the airbag gradually fills the space between the opening of the rotating pot body and the outside of the lid. The airbag and the guide ring form an air spring at the opening of the rotating pot body for buffering. Even if the rotating pot body rotates driven by the main shaft, the lid and the feed pipe can squeeze the air spring in the radial direction, leaving a runout margin, which can relieve the radial load of the main shaft of the transmission mechanism, which is beneficial to reduce the noise during the granulation process and optimize the environmental performance of the granulation equipment. At the same time, the feed pipe can continuously add material, and the wet raw material is spherical in the rotating pot body, and then the machine is stopped and taken out.
[0008] The outer edge of the airbag is bonded with an annular oil film, which lubricates the outer edge of the airbag and the opening of the rotating pot body, reduces friction, and prevents the airbag from being worn.
[0009] A pressure relief valve is fixed through the outer surface of the lid, and one end of the pressure relief valve extends into the interior of the rotating pot body. Since the opening of the rotating pot body is closed by the air spring and the lid, a closed environment is formed. After adding materials, the internal pressure increases until the pressure relief valve is pushed open, and the excess air is discharged into the factory environmental protection treatment system to prevent the pot from exploding.
[0010] An extension portion is integrally installed radially on the outer edge of the lid, and the diameter of the extension portion is larger than the diameter of the opening of the rotating pot body. It is tightly attached to the outer edge of the opening of the rotating pot body from the outside, and can cooperate with the guide ring to limit it from the inside and the outside respectively, so as to facilitate flattening the airbag at the opening of the rotating pot body.
[0011] A hopper is fixed to the end of the feed pipe away from the rotating pot body, and a feed pump is fixed to the feed port of the hopper. The hopper is supported by industrial steel and suspended above the rotating pot body. The output end of the feed pump is inserted into the raw material bag or raw material box with a hose, and then the pump is started to absorb the raw materials, first sent into the feed hopper for concentration, and then transported to the inside of the rotating pot body along the feed pipe.
[0012] The rotary pot body discharge port is hinged with a discharge door, which is closed during granulation. After the granules are granulated into balls, the machine is stopped, the rotary pot body discharge port is turned downward, and the discharge door is opened to discharge the spherical materials, which are then sent to the baking oven for sintering and hardening.
[0013] The technical effects achieved by this utility model are:
[0014] The present invention provides a practical granulating device for processing zirconium silicate ceramic sandblasting beads. When processing zirconium silicate ceramic sandblasting beads, the cover is moved to drive the lower end of the feed pipe to be inserted into the interior of the rotating pot body until the cover covers the opening of the rotating pot body, and then the air inlet pipe is opened and the air pump is used to inflate the interior of the airbag to expand and extend the airbag, and the guide ring is used to support and guide the airbag so that the airbag gradually fills the space between the opening of the rotating pot body and the outer side of the cover. The airbag and the guide ring form an air spring at the opening of the rotating pot body for buffering. Even if the rotating pot body rotates driven by the main shaft, the cover and the feed pipe can squeeze the air spring in the radial direction, leaving a jump margin, which can relieve the radial load of the main shaft of the transmission mechanism, is beneficial to reducing noise during the granulation process, and optimizes the environmental protection performance of the granulation equipment. At the same time, the feed pipe can continuously add material, and the wet raw material is spherical in the rotating pot body, and then the machine is stopped and taken out.

When the lid 2 is moved, the lower end of the feed pipe 3 is driven to be inserted into the interior of the rotating pot body 1 until the lid 2 covers the opening of the rotating pot body 1, and then the air inlet pipe 6 is opened and the air pump is used to inflate the air bag 4 to expand and extend the air bag 4, and the guide ring 5 is used to support and guide the air bag 4 so that the air bag 4 gradually fills the space between the opening of the rotating pot body 1 and the outside of the lid 2. The air bag 4 and the guide ring 5 form an air spring at the opening of the rotating pot body 1 for buffering. Even if the rotating pot body 1 and the air spring rotate under the drive of the main shaft, the lid 2 and the feed pipe 3 can squeeze the air spring in the radial direction, leaving a runout margin, which can relieve the radial load of the main shaft of the transmission mechanism, which is beneficial to reduce the noise during the granulation process and optimize the environmental performance of the granulation equipment. At the same time, the feed pipe 3 can be continuously fed, and the moistened raw materials are spherical in the rotating pot body 1, and then the machine is stopped and taken out.
[0024] Among them, the air inlet end of the air inlet pipe 6 can be closed by a solenoid valve, and the opening and closing can be controlled by program, which saves time and effort. The air inlet pipe 6 is made of hard alloy and can stably support the lid 2 after being fixed, so that it is convenient to suspend it at the opening of the rotating pot body 1.

[0026] like Figure 1 and Figure 2 As shown, a pressure relief valve 8 is fixed through the outer surface of the lid 2, and one end of the pressure relief valve 8 extends into the interior of the rotating pot body 1. Since the opening of the rotating pot body 1 is closed by the air spring and the lid 2, a closed environment is formed. After adding materials, the internal pressure increases until the pressure relief valve 8 is pushed open, and the excess air is discharged into the factory environmental protection treatment system to prevent the pot from exploding.
[0027] like Figure 1 , pictures and Figure 3As shown, an extension portion 9 is integrally installed radially on the outer edge of the lid 2.

[0029] like Figure 1 As shown, the discharge port of the rotating pot body 1 is hinged with a discharge door 12, which is closed during granulation. After the granules are granulated into balls, the machine is stopped, and the discharge port of the rotating pot body 1 is turned downward, and the discharge door 12 is opened to discharge the spherical materials, which are then sent to the baking oven for sintering and hardening.
[0030] The working principle of the utility model is as follows: when processing zirconium silicate ceramic sandblasting beads, the cover 2 is moved to drive the lower end of the feed pipe 3 to be inserted into the interior of the rotating pot body 1 until the cover 2 covers the opening of the rotating pot body 1, and then the air inlet pipe 6 is opened and an air pump or an air pump is used to inflate the interior of the airbag 4 to make the airbag 4 expand and extend, and the guide ring 5 is used to support and guide the airbag 4 so that the airbag 4 gradually fills the space between the opening of the rotating pot body 1 and the outside of the cover 2, and the airbag 4 and the guide ring 5 form an air spring at the opening of the rotating pot body 1 for buffering.
[0031] Even if the rotating pot body 1 and the air spring rotate driven by the main shaft, the cover 2 and the feed pipe 3 can squeeze the air spring in the radial direction, leaving a runout margin, which can alleviate the radial load of the main shaft of the transmission mechanism, is beneficial to reducing noise during the granulation process, and optimizes the environmental performance of the granulation equipment.
[0032] At the same time, the feed pipe 3 can continuously add materials, and the wet raw materials are spherical in the rotating pot body 1, and then the machine is stopped and taken out.
