Description

Technical Field

[0001] The utility model belongs to the technical field of granulators, and particularly relates to a residual sand cleaning device for zirconium silicate ceramic sandblasting beads processing. Background Art

[0002] The zirconium silicate ceramic sandblasting bead manufacturing process begins with preparing zirconium silicate powder and appropriate additives, such as binders and lubricants. These are mixed in a defined ratio to form a uniform mixture. The mixture is then placed in a pot-type granulator and rotated to form the desired shape and size. The formed ceramic granules are then sintered in a high-temperature furnace, causing the materials within the granules to fuse and crystallize, forming a dense ceramic structure.

[0003] Because the wet mixture becomes viscous after being hydrated, it partially adheres to the inner wall of the pot pellet mill, forming sand scale that easily blocks the pellets and reduces the roundness of the pellets. Pot pellet mills are generally equipped with built-in high-pressure water spray balls or high-pressure water spray pipes. Using a water pump to boost pressure, high-pressure water is sprayed onto the inner wall of the pot to flush away the sand scale and clean it.

[0004] When cleaning sand scale in the existing pot-type granulator, a high-pressure water flow is sprayed toward its inner circle with a high-pressure water pipe, and the sand scale flows out from the lower discharge door. The sand scale becomes sticky after absorbing water and becomes wet. After being washed away, it adheres to the sand scale below to produce residue. The internal area of the cylinder is large, and repeated flushing is often required, which makes it inconvenient to quickly clean the residual sand scale in the pot-type granulator. For this reason, we propose a residual sand cleaning device for zirconium silicate ceramic sandblasting beads processing. Utility Model Content

[0005] The purpose of this utility model is to provide a residual sand cleaning device for zirconium silicate ceramic sandblasting bead processing, which can flush water on the inner wall of the cylinder and spray soap liquid at the same time for lubrication, thereby reducing the adhesion between the residual sand particles after being wetted, and using the jet inertia to quickly clean the residual sand scale in the pot-type granulator.

[0006] The technical solutions adopted in this application are as follows:

[0007] A device for cleaning residual sand particles used in sandblasting zirconium silicate ceramics, comprising a high-pressure water pipe and a nozzle connected to the high-pressure water pipe, a rotary joint provided between the high-pressure water pipe and the nozzle, the rotary joint comprising a stator portion and a rotor portion adapted to the stator portion, one end of the stator portion being fixedly connected to one end of the high-pressure water pipe, one end of the rotor portion being fixedly connected to one end of the nozzle, the other end of the nozzle being oriented in an axial direction offset from the rotor portion, and a soap liquid tube being fixedly attached to the outside of the high-pressure water pipe;

[0008] It also includes a support plate and a cylinder fixedly connected to the support plate. The support plate is in the shape of a square plate with a hole and the hole is fixedly connected to the stator. The axial direction of the cylinder output end is parallel to the axial direction of the rotor part. When cleaning sand particles, the cylinder is fixed at the opening of the cylinder, and the rotary joint and the nozzle are inserted into the interior of the cylinder to make the axis of the rotor part and the axis of the cylinder coincide as much as possible. First, start the high-pressure water pump, open the high-pressure water pipe and the soap liquid pipe, and deliver high-pressure water and soap water to the nozzle along the rotary joint. Spray from the other end of the nozzle to the inner circle of the cylinder. Due to the relative position of the nozzles, The deflection of the rotary joint can be rotated unidirectionally around the rotary joint under the reaction of the jet, and then the cylinder on the support plate is started to move the rotary joint along the axis of the cylinder, which can increase the spray area of the nozzle, and spray soap liquid on the inner wall of the cylinder while flushing water to lubricate and reduce the adhesion between the residual sand particles after they are wetted. After a layer of soap liquid is coated on the inner wall of the cylinder, the soap liquid pipe is closed, and the high-pressure water pump is controlled to pump water intermittently. The nozzle intermittently jets to flush and vibrate the cylinder, and the jet inertia is used to quickly clean the residual sand scale in the pot-type granulator.

[0009] A cylinder seat is fixed to the lower surface of the cylinder, and two legs distributed in an eight-shaped pattern are fixed on both sides of the cylinder seat. The cylinder seat and the two legs are used to support the opening of the cylinder, so that the cylinder can be as close to the center axis of the cylinder as possible.

[0010] A concave clamp is fixed on one end of the two legs away from the cylinder seat. The opening directions of the two concave clamps are both away from the cylinder seat, and they are respectively clamped on the lower edge of the cylinder opening, which can support and limit from both sides of the cylinder, thereby improving the reliability of fixing the cylinder.

[0011] A locking bolt is threadedly installed on one side of the two concave clamps. The locking bolt is rotated forward until it touches the outer surface of the cylinder, so that the two concave clamps are pressed against the cylinder and locked under the action of friction, thereby further improving the reliability of fixing the cylinder. Conversely, the locking bolt is reversed to disengage from the cylinder to release the locked state.

[0012] A one-way valve is fixed on the soap liquid pipe, so that the soap liquid inside the soap liquid pipe can only flow toward the high-pressure water pipe, preventing the high pressure in the high-pressure water pipe from flowing into the soap liquid pipe.

[0013] A bracket with a lower-opening hollow trapezoidal structure is fixed on the upper surface of the cylinder seat. The upper surface of the bracket has an arc and is slidably connected to the high-pressure water pipe, supporting the high-pressure water pipe to suspend above the cylinder to prevent it from getting caught on the cylinder and causing interference during movement.

[0014] The technical effects achieved by this utility model are:

When cleaning sand, the cylinder is fixed at the opening of the cylinder, the rotary joint and the nozzle are inserted into the interior of the cylinder, the high-pressure water pump is started first, the high-pressure water pipe and the soap liquid pipe are opened, and the high-pressure water and soap liquid are transported to the nozzle along the rotary joint, and sprayed from the other end of the nozzle to the inner circle of the cylinder.

[0023] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0024] like Figure 1-5As shown, a residual sand cleaning device for zirconium silicate ceramic sandblasting beads processing includes a high-pressure water pipe 1 and a nozzle 2 connected to the high-pressure water pipe 1. A rotary joint 3 is provided between the high-pressure water pipe 1 and the nozzle 2. The rotary joint 3 consists of a stator portion and a rotor portion adapted to the stator portion. One end of the stator portion is fixedly connected to one end of the high-pressure water pipe 1, and the other end of the high-pressure water pipe 1 is connected to a high-pressure water pump. One end of the rotor portion is fixedly connected to one end of the nozzle 2, and the other end of the stator portion is rotatably connected to the other end of the rotor portion. The direction of the other end of the nozzle 2 is staggered with the axial direction of the rotor portion. A soap liquid pipe 4 is fixed to the outside of the high-pressure water pipe 1, and the liquid outlet end of the soap liquid pipe 4 is connected to the inside of the high-pressure water pipe 1 through a tee.

[0025] It also includes a support plate 5 and a cylinder 6 fixedly connected to the support plate 5. The cylinder 6 can be purchased from a waterproof pneumatic column on the market. The output end of the cylinder 6 is fixedly connected to one side of the support plate 5. The support plate 5 is in the shape of a square plate with a hole and the hole is fixedly connected to the stator. The axial direction of the output end of the cylinder 6 is parallel to the axial direction of the rotor. The raw materials of zirconium silicate ceramic sandblasting beads are roll-formed in a pot-type granulator. Part of the raw materials adhere to the inner wall of the cylinder, forming residual sand particles that easily block subsequent rolling particles. When cleaning the sand particles, fix the cylinder 6 at the opening of the cylinder, and the rotary joint 3 and the nozzle 2 are inserted into the interior of the cylinder so that the axis of the rotor and the axis of the cylinder are as close as possible. Start the high-pressure water pump first, open the high-pressure water pipe 1 and the soap liquid pipe 4, and rotate the rotary joint 3. High-pressure water and soapy water are delivered to the nozzle 2 and sprayed onto the inner circle of the cylinder from the other end of the nozzle 2. Since the nozzle 2 is tilted relative to the rotary joint 3, it can rotate unidirectionally around the rotary joint 3 under the reaction of the jet. Then the cylinder 6 on the support plate 5 is started to move the rotary joint 3 along the axis of the cylinder, which can increase the spraying area of the nozzle 2. The inner wall of the cylinder is flushed with water while being sprayed with soapy liquid for lubrication, thereby reducing the adhesion between the residual sand particles after being wetted. After a layer of soapy liquid is coated on the inner wall of the cylinder, the soapy liquid pipe 4 is closed, and the high-pressure water pump is controlled to pump water intermittently. The nozzle 2 intermittently jets to flush and vibrate the cylinder, and the residual sand scale in the pot-type granulator is quickly cleaned by the jet inertia, so that the water flow carries the sand particles and discharges them from the cylinder discharge port.

[0026] The opening or closing of the high-pressure water pipe 1 and the soap liquid pipe 4 can be controlled by installing electromagnetic valves on both of them and utilizing the on and off of the electromagnetic valves. This technical solution is a prior art and is not shown in the figure.

[0027] like Figure 2 、 Figure 3 and Figure 4 As shown, a cylinder base 7 is fixed to the lower surface of the cylinder 6, and the upper surface of the cylinder base 7 is fixedly connected to the lower surface of the cylinder 6. Two legs 8 distributed in an eight-shape are fixed on both sides of the cylinder base 7. The upper ends of the two legs 8 are detachably connected to the two sides of the cylinder base 7. The cylinder base 7 and the two legs 8 are used for support at the opening of the cylinder body, so that the cylinder 6 can be as close to the center axis of the cylinder body as possible.

[0028] like Figure 2 、 Figure 3 and Figure 5 As shown, a concave clamp 9 is fixed to one end of the two legs 8 away from the cylinder seat 7. The opening directions of the two concave clamps 9 are both away from the cylinder seat 7, and are respectively clamped on the lower edge of the cylinder opening. They can support and limit from both sides of the cylinder body, thereby improving the reliability of fixing the cylinder 6.

[0029] like Figure 2 and Figure 5 As shown, one side of the two concave clips 9 is threaded with a locking bolt 10. The locking bolt 10 is rotated forward until it touches the outer surface of the cylinder, so that the two concave clips 9 are close to the cylinder and locked under the action of friction, thereby further improving the reliability of fixing the cylinder 6. Conversely, the locking bolt 10 is reversed to disengage from the cylinder to release the locked state.

[0030] like Figure 1 As shown, a one-way valve 11 is fixed on the soap liquid pipe 4, so that the soap liquid inside the soap liquid pipe 4 can only flow toward the high-pressure water pipe 1, preventing the high pressure in the high-pressure water pipe 1 from flowing into the soap liquid pipe 4.

[0031] like Figure 1 、 Figure 2 and Figure 4 As shown, a bracket 12 with a hollow trapezoidal structure with a lower opening is fixed to the upper surface of the cylinder seat 7. The two sides of the lower end of the bracket 12 are respectively located on both sides of the cylinder 6 and are fixedly connected to the upper surface of the cylinder seat 7. The upper surface of the bracket 12 has an arc and is slidably connected to the high-pressure water pipe 1, preferably sliding in a chute manner, supporting the high-pressure water pipe 1 to be suspended above the cylinder 6 to prevent it from getting caught on the cylinder 6 and causing interference during movement.

[0032] The working principle of this utility model is as follows: when cleaning sand particles, the cylinder 6 is fixed at the opening of the cylinder, the rotary joint 3 and the nozzle 2 are inserted into the interior of the cylinder, and the axis of the rotor part and the axis of the cylinder are made to coincide as much as possible. First, the high-pressure water pump is started, the high-pressure water pipe 1 and the soap liquid pipe 4 are opened, and high-pressure water and soapy water are delivered to the nozzle 2 along the rotary joint 3, and sprayed from the other end of the nozzle 2 to the inner circle of the cylinder. Since the nozzle 2 is deflected relative to the rotary joint 3, it can rotate unidirectionally around the rotary joint 3 under the reaction of the jet.

[0033] Restarting the cylinder 6 on the support plate 5 and moving the rotary joint 3 along the axis of the cylinder can increase the spraying area of the nozzle 2, flushing the inner wall of the cylinder with water while spraying soapy liquid for lubrication, reducing the adhesion between the residual sand particles after being wetted.

[0034] After a layer of soap liquid is coated on the inner wall of the cylinder, the soap liquid pipe 4 is closed, the high-pressure water pump is controlled to pump water intermittently, and the nozzle 2 intermittently jets to flush and vibrate the cylinder. The residual sand scale in the pot-type granulator is quickly cleaned by the inertia of the jet, and the water flow carries the sand and is discharged from the discharge port of the cylinder.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
