Abstract
Description
Technical Field
[0001] This application relates to the field of sandblasting equipment technology, and in particular to a sand separating device for a sandblasting machine. Background Technology
[0002] Sandblasting machines use compressed air as power to form a high-speed jet that propels abrasive materials (steel grit, quartz sand, corundum, glass sand, resin sand, etc.) onto the surface of the workpiece to be treated. Due to the impact and cutting action of the abrasive on the workpiece surface, the workpiece surface achieves a certain degree of cleanliness and different roughness, thereby improving the mechanical properties of the workpiece surface. This enhances the fatigue resistance of the workpiece and increases the adhesion between the workpiece surface and the coating. The sand separator is an important component of the sandblasting machine.
[0003] In the existing technology, the main function of the sand separator is to perform cyclone separation by gravity, that is, to separate usable sand from waste sand. During the separation process, the waste sand is sucked away by the pipe at the top of the sand separator, while the sand falls to the bottom of the sand separator and is then sanded again by the spray gun.
[0004] However, when the sand falls into the sand distributor, due to the differences in particle size of different components and airflow disturbances, the sand accumulates unevenly at the bottom of the sand distributor, resulting in local accumulation that is too high or too low. When the sand accumulation at the bottom of the sand distributor is uneven, the sand supply in different areas during the sandblasting process will vary, resulting in unstable sand concentration sprayed from the spray gun, which reduces the sandblasting quality of the sandblasting machine and has obvious deficiencies. Utility Model Content
[0005] In order to improve the sandblasting quality of sandblasting machines, this application provides a sand separating device for sandblasting machines.
[0006] The sand separating device for a sandblasting machine provided in this application adopts the following technical solution:
[0007] A sand-separating device for a sandblasting machine includes a sandblasting machine body, a sand separator for storing sand on the sandblasting machine body, a vibration assembly on the sand separator, and a pneumatic vibrator disposed on the outer surface of the sand separator, the pneumatic vibrator being connected to an air source through a pneumatic control pipeline.
[0008] By adopting the above technical solution, during the sandblasting process, a pneumatic vibrator is used to vibrate the sand distributor. The sand flows inside the sand distributor with the vibration, thereby breaking the uneven accumulation state of the sand inside the sand distributor caused by factors such as particle differences. This allows the sand of different components to be fully mixed, improving the uniformity of the sand inside the sand distributor, and thus improving the sandblasting quality of the sandblasting machine.
[0009] Optionally, the vibration assembly further includes a throttle valve disposed on the pneumatic control line, the throttle valve being used to control the gas flow rate entering the pneumatic vibrator.
[0010] By adopting the above technical solution, workers can regulate the gas flow rate into the pneumatic vibrator through a throttle valve, thereby adjusting the force exerted by the pneumatic vibrator on the sand separator during vibration. During sandblasting, workers can adjust the force to the range of 2-3 bar to reduce the impact of vibration on the connection between the sand separator and the pneumatic vibrator.
[0011] Optionally, the vibration assembly further includes a solenoid valve disposed on the pneumatic control pipeline. The solenoid valve is connected to the control system via an electrical control pipeline and is used to control the vibration duration and working interval of the pneumatic vibrator.
[0012] By adopting the above technical solution, during sandblasting, workers control the vibration duration and interval through solenoid valves, so that the pneumatic vibrator runs intermittently. This allows the sand inside the sand separator to settle and redistribute naturally during the interval, further optimizing the sand separation effect, while preventing the equipment from overheating or consuming too much energy due to continuous vibration.
[0013] Optionally, the outer surface of the sand separator is provided with a mounting base, and the pneumatic vibrator is detachably connected to the mounting base by mounting screws.
[0014] By adopting the above technical solution, when the pneumatic vibrator malfunctions or needs maintenance, the mounting screws can be quickly removed and the vibrator taken off the mounting base, improving the convenience of worker operation.
[0015] Optionally, a protective shell is provided on the surface of the mounting base facing the pneumatic vibrator. Protective arc plates are slidably connected to both sides of the mounting base and the protective shell. The mounting base has a groove for the protective arc plates to pass through. Each end of the protective arc plate is provided with a connecting plate. Both connecting plates have clearance grooves for the installation of the pneumatic control pipeline. When the two connecting plates are connected by a fixing component, the protective shell and the two protective arc plates together cover the outer periphery of the pneumatic vibrator.
[0016] By adopting the above technical solution, when installing the pneumatic vibrator, the worker pushes the protective arc plate to one side of the mounting base, and then installs the pneumatic vibrator with mounting screws. After installation, the worker pulls the two protective arc plates to move them through the groove to one side of the protective shell, and connects the two connecting plates with the fixing components. In this way, the pneumatic vibrator is placed in the closed area enclosed by the two protective arc plates and the protective shell, reducing the possibility of the pneumatic vibrator falling and being damaged when the mounting screws loosen. At the same time, it isolates the influence of external forces on the operation of the pneumatic vibrator, ensuring the safety of the pneumatic vibrator during operation.
[0017] Optionally, the fixing component includes a pin rod, and the two connecting plates are provided with pin holes that slide with the pin rod. One end of the pin rod is provided with an abutment block, and the other end is provided with a threaded section. The outer surface of the threaded section is threaded with an inner threaded sleeve, and the opposing surfaces of the inner threaded sleeve and the abutment block abut against the outer surface of the connecting plate.
[0018] By adopting the above technical solution, when connecting the two connecting plates, the worker passes the pin rod through the two pin holes and makes the abutment block fit tightly against the surface of one side of the connecting plate. Then, the inner thread sleeve is screwed onto the threaded section and gradually tightened to make it abut against the other side of the connecting plate. In this way, the two connecting plates are fixed, thereby forming protection for the pneumatic vibrator.
[0019] Optionally, the mounting base and the protective shell are provided with arc grooves on opposite sides, and the protective arc plate is provided with guide blocks that slide in cooperation with the arc grooves on opposite sides.
[0020] By adopting the above technical solution, the setting of the arc groove and guide block restricts the movement trajectory of the protective arc plate, effectively reducing the possibility of the protective arc plate deviating when sliding, thereby ensuring the direct connection of the two pin holes, and at the same time facilitating workers to move the protective arc plate quickly, improving the convenience of workers' operation.
[0021] Optionally, a magnetic sheet is embedded in the guide block on the side facing the mounting base, and a magnetic block for attracting the magnetic sheet is provided on the inner wall of the arc groove away from the protective shell.
[0022] By adopting the above technical solution, when workers install the pneumatic vibrator, the magnetic attraction between the magnetic block and the magnetic sheet fixes the protective arc plate to one side of the mounting base, thereby restricting the sliding of the protective arc plate. This avoids the protective arc plate from accidentally sliding to the side of the protective shell and obstructing the operating space during the installation of the pneumatic vibrator, reducing the tedious steps of workers repeatedly adjusting the position of the protective arc plate, and thus improving the installation efficiency of the pneumatic vibrator.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. This application sets up a vibration component, and during the sandblasting process, a pneumatic vibrator is used to vibrate the sand distributor. The sand flows inside the sand distributor with the vibration, thereby breaking the uneven accumulation state of the sand inside the sand distributor caused by factors such as particle differences. This allows the sand of different components to be fully mixed, improves the uniformity of the sand inside the sand distributor, and thus improves the sandblasting quality of the sandblasting machine.
[0025] 2. By setting up a protective shell, protective arc plates, and fixing components, after the pneumatic vibrator is installed, the worker pulls the two protective arc plates to move them through the grooves to one side of the protective shell, and connects the two connecting plates through the fixing components. In this way, the pneumatic vibrator is placed in the closed area enclosed by the two protective arc plates and the protective shell, reducing the possibility of the pneumatic vibrator falling and being damaged when the mounting screws loosen. At the same time, it isolates the influence of external forces on the operation of the pneumatic vibrator, ensuring the safety of the pneumatic vibrator during operation. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0032] This application discloses a sand separating device for a sandblasting machine.
[0033] Reference Figure 1 A sand-separating device for a sandblasting machine includes a sandblasting machine body 1, a sand separator 2 for storing sand is installed on the sandblasting machine body 1, and a vibration component 3 is provided on the sand separator 2. The vibration force generated by the vibration component 3 causes the sand separator 2 to vibrate.
[0034] Reference Figure 1 and Figure 2A mounting base 4 is fixedly installed on the outer surface of the sand separator 2. A pneumatic vibrator 31 is detachably connected to the mounting base 4 by mounting screws 5. The pneumatic vibrator 31 is connected to the air source through a pneumatic control pipeline 32. A throttle valve 33 is fixedly installed on the pneumatic control pipeline 32. The throttle valve 33 is used to control the flow rate of the gas entering the pneumatic vibrator 31, thereby adjusting the magnitude of the force exerted by the pneumatic vibrator 31 on the sand separator 2 when it vibrates.
[0035] Before the sandblasting machine is run, the worker installs the pneumatic vibrator 31 on the mounting base 4 using mounting screws 5. Then, the vibration force of the pneumatic vibrator 31 is adjusted to the range of 2-3 bar using the throttle valve 33, thereby reducing the possibility of the mounting screws 5 loosening. When the pneumatic vibrator 31 vibrates the sand distributor 2, the sand flows inside the sand distributor 2 with the vibration, thereby breaking the uneven accumulation state of the sand inside the sand distributor 2 caused by factors such as particle differences. This allows the sand of different components to be fully mixed, improving the uniformity of the sand inside the sand distributor 2, and thus improving the sandblasting quality of the sandblasting machine.
[0036] Reference Figure 1 and Figure 2 The vibration assembly 3 also includes a solenoid valve 34 installed on the pneumatic control line 32. The solenoid valve 34 is connected to the control system of the sandblasting machine through the electrical control line 35. A controller 36 is installed on the solenoid valve 34. A knob 361 and a knob 362 are rotatably connected to the controller 36. Knob 361 is used to control the vibration duration of the pneumatic vibrator 31, and knob 362 is used to control the working interval time.
[0037] Before sandblasting, workers set the vibration duration and interval of the pneumatic vibrator 31 by turning knob 361 and knob 362, so that the pneumatic vibrator 31 runs intermittently. This allows the sand inside the sand separator 2 to settle and redistribute naturally during the interval, further optimizing the sand separation effect, while preventing the equipment from overheating or consuming too much energy due to continuous vibration.
[0038] Reference Figure 3 and Figure 4 A protective shell 6 is fixedly connected to the surface of the mounting base 4 facing the pneumatic vibrator 31. Multiple heat dissipation slots 61 are opened on the outer surface of the protective shell 6. Arc grooves 7 are opened on the inner sidewalls of the mounting base 4 and the protective shell 6 respectively. The two arc grooves 7 are interconnected and concentrically arranged. A guide block 81 is slidably connected inside each arc groove 7. The cross-section of the guide block 81 and the arc groove 7 can be set as T-shaped to improve the connection stability. In this embodiment, taking a square shape as an example, a protective arc plate 8 is connected to the two guide blocks 81 on the same side. The protective arc plate 8 is slidably connected to the mounting base 4 and the protective shell 6.
[0039] Reference Figure 3 and Figure 4The mounting base 4 has a groove 41 for the protective arc plate 8 to pass through. The arc groove 7 is connected to the groove 41. Each protective arc plate 8 has a connecting plate 82 fixedly connected to its end. The connecting plate 82 has a clearance groove 83 for the installation of the pneumatic control pipeline 32. When the two connecting plates 82 are connected by the fixing component 9, the protective shell 6 and the two protective arc plates 8 together cover the outer periphery of the pneumatic vibrator 31.
[0040] Reference Figure 3 and Figure 4 The fixing component 9 includes a pin rod 91. Two connecting plates 82 are provided with pin holes 821 that slide with the pin rod 91. One end of the pin rod 91 is fixedly connected to an abutment block 92, and the other end of the rod body is provided with a threaded section 93. The outer surface of the threaded section 93 is threadedly connected to an inner threaded sleeve 94. The opposing surfaces of the inner threaded sleeve 94 and the abutment block 92 abut against the outer surface of the connecting plate 82.
[0041] When installing the pneumatic vibrator 31, the worker pushes the protective arc plate 8 to one side of the mounting base 4, and then installs the pneumatic vibrator 31 with the mounting screw 5. After installation, the worker pulls the two protective arc plates 8 towards the protective shell 6. Under the guidance of the arc groove 7 and the guide block 81, the two protective arc plates 8 move to one side of the protective shell 6 through the groove 41 and the two connecting plates 82 abut against each other. At this time, the worker passes the pin rod 91 through the two pin holes 821 and makes the abutting block 92 tightly fit against the surface of one side of the connecting plate 82. Finally, the inner thread sleeve 94 is screwed onto the thread section 93 and gradually tightened to make it abut against the other side of the connecting plate 82. In this way, the two connecting plates 82 are fixed, so that the pneumatic vibrator 31 is in the closed area enclosed by the two protective arc plates 8 and the protective shell 6, reducing the possibility of the pneumatic vibrator 31 falling and being damaged when the mounting screw 5 is loose. At the same time, it isolates the influence of external forces on the operation of the pneumatic vibrator 31, ensuring the safety of the pneumatic vibrator 31 during operation.
[0042] When the pneumatic vibrator 31 malfunctions or requires maintenance, the worker loosens the inner threaded sleeve 94, grasps the abutment block 92, and pulls out the pin rod 91. The connection between the two connecting plates 82 is lost. The worker separates the pneumatic control line 32 from the pneumatic vibrator 31 through the clearance groove 83. Then, the worker moves the protective arc plate 8 toward the mounting base 4, exposing the pneumatic vibrator 31 on the mounting base 4. Finally, the worker loosens the mounting screw 5 and removes the pneumatic vibrator 31.
[0043] Reference Figure 3 and Figure 4A magnetic sheet 811 is fixedly embedded on the side of the guide block 81 facing the mounting base 4. A magnetic block 71 for adsorbing the magnetic sheet 811 is fixedly connected on the inner wall of the arc groove 7 away from the protective shell 6. When the worker installs the pneumatic vibrator 31, the magnetic attraction between the magnetic block 71 and the magnetic sheet 811 fixes the protective arc plate 8 to one side of the mounting base 4, thereby preventing the protective arc plate 8 from accidentally sliding during the installation of the pneumatic vibrator 31.
[0044] The implementation principle of a sand-separating device for a sandblasting machine according to an embodiment of this application is as follows: Before the sandblasting machine is run, the worker installs the pneumatic vibrator 31 on the mounting base 4 using mounting screws 5. Then, the vibration force of the pneumatic vibrator 31 is adjusted to the range of 2-3 bar using the throttle valve 33, thereby reducing the possibility of the mounting screws 5 loosening. When the pneumatic vibrator 31 vibrates the sand separator 2, the sand flows inside the sand separator 2 with the vibration, thereby breaking the uneven accumulation state of the sand inside the sand separator 2 caused by factors such as particle differences, so that the sand of different components can be fully mixed, improving the uniformity of the sand inside the sand separator 2, and thus improving the sandblasting quality of the sandblasting machine.
[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
