Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a bubbling stirring device and wet sandblasting equipment. Background Art

[0002] In wet sandblasting equipment, an abrasive liquid formed by a uniform mixture of liquid water and abrasives needs to be configured in the abrasive box, and the abrasive liquid is sprayed onto the surface of the workpiece by a spray gun through the power provided by the abrasive liquid pump and compressed air to achieve the effects of rust removal, burr removal, surface hardening, etc. Compared with dry sandblasting, wet sandblasting has the advantages of no dust generation during the sandblasting process, high work efficiency, and low abrasive consumption. However, in order to ensure the sandblasting quality of the abrasive liquid, wet sandblasting requires abrasives made of materials such as aluminum oxide, ceramics, and glass to be evenly mixed in liquid water without sinking. In the prior art, there is a problem of lack of a powerful stirring device to mix the abrasive liquid evenly. The patent with publication number CN208246604U uses an impeller stirrer to ensure the uniform mixing of the abrasive liquid. However, in addition to the need to add a drive motor, which increases cost and structural complexity, this stirring device also has the problem of dead corners of sedimentation at the bottom of the abrasive liquid box. Utility Model Content

[0003] In order to solve the technical problems existing in the background technology, the utility model proposes a bubbling stirring device which can stir the grinding liquid uniformly in all directions and has a simple and reliable structure, and a wet sandblasting equipment including the bubbling stirring device.

[0004] The bubbling stirring device includes: a container for containing a liquid-solid mixture to be stirred, an air guide pipe, and a high-pressure air source. The air guide pipe is spirally arranged along the inner wall of the container from the bottom of the container to the top of the container and is fixed to the inner wall of the container. The bottom opening of the air guide pipe is connected to the high-pressure air source through the air pipe. The top of the air guide pipe is a closed structure. A plurality of bubbling holes connected to the inner cavity of the air guide pipe are evenly arranged on the wall of the air guide pipe that contacts the liquid-solid mixture to be stirred.

[0005] Preferably, the high-pressure gas source is provided by an air compressor, and a pressure regulating valve is connected between the air compressor and the bottom opening of the air guide pipe.

[0006] Preferably, the pore size of the bubble hole should be within the range of 1 / 3-1 / 2 the diameter of the air guide tube.

[0007] Preferably, the bubbling stirring device also includes a plurality of fixed buckles, and an installation groove for accommodating the fixed air guide tube is opened on the inner wall of the container. The fixed buckle can press the air guide tube against the inner wall of the container and fix it. The upper and lower ends of the fixed buckle are fixed to the inner wall of the container by screw connection or other connection methods.

[0008] Preferably, the air guide tube is made of stainless steel or PVC.

[0009] Preferably, the compressed air delivery pipe and the air guide pipe connected to the spray gun share a common air compressor.

[0010] Compared with the prior art, the beneficial effects of the bubbling stirring device of the utility model are:

[0011] Since the air guide tube extends from the bottom of the container to the top of the container, the mixture to be stirred at each liquid level can be mixed more comprehensively and effectively, thereby achieving a better stirring effect. Compared with the stirring device using an impeller mechanism, it can also effectively prevent the solid phase from forming a precipitation dead corner at the bottom of the container. The air guide tube is spirally extended from the bottom of the container to the top of the container and is spirally fixed on the inner wall of the container. This design structure can not only surround the mixture to be stirred in the bubbling hole in all directions, thereby improving the bubbling stirring effect, but also make the air guide tube into an integrated simple structure, and at the same time facilitate the connection between the air guide tube and the high-pressure gas source.

[0012] The pressure regulating valve can maintain the pressure of the high-pressure gas from the air compressor within the range where it can work efficiently, thereby improving the reliability of the bubbling stirring device.

[0013] The utility model also provides a wet sandblasting device, comprising a wet sandblasting device body and the above-mentioned bubbling stirring device. The grinding liquid box in the wet sandblasting device body is the container in the bubbling stirring device.

[0014] Preferably, the high-pressure gas delivery pipe connected to the spray gun and the air guide pipe share a high-pressure gas source.

[0015] Compared with the prior art, the beneficial effects of the wet sandblasting equipment of the utility model are:

[0016] By simply improving the structure of the grinding liquid box and at a relatively low improvement investment cost, a bubbling stirring device can be obtained that can reliably and evenly mix the abrasive in the grinding liquid in all directions without dead angles, thereby ensuring the mixing uniformity of the grinding liquid and thus ensuring the sandblasting quality of the wet sandblasting equipment.

[0017] The high-pressure delivery pipe and the air guide pipe connected to the spray gun share a high-pressure gas source, which can reduce equipment costs and simplify structural design. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific implementation of the present utility model will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 and Figure 2 The bubbling stirring device includes: a container 1 for containing a liquid-solid phase mixture to be stirred, an air guide pipe 2, and a high-pressure gas source 3. The air guide pipe 2 is spirally arranged along the inner wall 11 of the container from the bottom of the container 1 to the top of the container 1 and is fixed on the inner wall 11 of the container. The bottom opening 21 of the air guide pipe is connected to the high-pressure gas source 3 through the air pipe. The top of the air guide pipe 2 is a closed structure. A plurality of bubbling holes 22 connected to the inner cavity of the air guide pipe 2 are evenly arranged on the wall of the air guide pipe 2 that contacts the liquid-solid phase to be stirred.

[0024] The working principle of the bubbling stirring device is as follows: the high-pressure gas in the high-pressure gas source 3 enters the bottom opening 21 of the air duct through the air pipe and continues to spray to the top of the air duct. The high-pressure gas filled in the air duct 2 will be sprayed out through the bubbling hole 22 to form small bubbles. The small bubbles pass through the liquid and solid phases to be stirred and strongly mix them, thereby playing a stirring role.

[0025] Since the air duct 2 extends from the bottom of the container 1 to the top of the container 1, the mixture to be stirred at each liquid level can be mixed more comprehensively and effectively, thereby achieving a better stirring effect. Compared with the stirring device using an impeller mechanism, it can also effectively prevent the solid phase from forming a precipitation dead corner at the bottom of the container 1. The air duct 2 is spirally extended from the bottom of the container 1 to the top of the container 1 and is spirally fixed on the inner wall 11 of the container. This design structure can not only surround the mixture to be stirred in the bubbling hole 22 in all directions, thereby improving the bubbling stirring effect, but also make the air duct 2 into an integrated simple structure, and also facilitate the connection between the air duct 2 and the high-pressure gas source.

[0026] Reference Figure 3 The high-pressure gas source 3 is provided by an air compressor, and a pressure regulating valve 4 is connected between the air compressor and the bottom opening 21 of the air guide pipe. The pressure regulating valve 4 can keep the pressure of the high-pressure gas coming out of the air compressor within the range of efficient operation, thereby improving the reliability of the bubbling stirring device.

[0027] In order to form larger and more powerful stirring bubbles and achieve better stirring effect, the aperture size of the bubbling hole should be within the range of 1 / 3-1 / 2 the diameter of the air guide tube.

[0028] Reference Figure 1 、 Figure 3The bubbling stirring device also includes a plurality of fixed buckles 5. An installation groove 111 for accommodating the fixed air guide tube 2 is opened on the inner wall 11 of the container. The fixed buckles 5 can press the air guide tube 2 against and fix it on the inner wall 11 of the container. The upper and lower ends of the fixed buckles 5 are fixed to the inner wall 11 of the container by screw connection or other connection methods. The fixed buckles 5 can firmly fix the air guide tube 2 on the inner wall 11 of the container, thereby enhancing the reliability of the bubbling stirring device.

[0029] In order to extend the service life of the air guide tube 2 while taking into account economy, the air guide tube 2 is made of stainless steel or PVC that is strong, durable and highly corrosion-resistant.

[0030] Reference Figure 4 The wet sandblasting equipment includes a wet sandblasting equipment body and the above-mentioned bubbling stirring device. The grinding liquid box 6 in the wet sandblasting equipment body is the container 1 described in the bubbling stirring device.

[0031] By simply improving the structure of the grinding liquid box and at a relatively low improvement investment cost, a bubbling stirring device can be obtained that can reliably and evenly mix the abrasive in the grinding liquid in all directions without dead angles, thereby ensuring the mixing uniformity of the grinding liquid and thus ensuring the sandblasting quality of the wet sandblasting equipment.

[0032] In actual application, the grinding liquid in the grinding liquid tank 6 is first extracted into the grinding liquid discharge pipe 7 through the grinding liquid pump 8. The grinding liquid discharge pipe 7 is connected to the spray gun 10 together with the compressed air delivery pipe 9. The grinding liquid in the grinding liquid discharge pipe 7 is sprayed onto the surface of the workpiece through the spray gun 10 under the acceleration power of the compressed air. The compressed air delivery pipe 9 is connected to the air compressor, so the compressed air delivery pipe 9 and the air guide pipe 2 can share an air compressor, reducing equipment costs and simplifying structural design.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
