[0026] Example

[0027] Reference Figure 1-Figure 3 This embodiment provides a sandblasting cleaning equipment, including a tank body 110, a feed pipe 120 is connected to the top of the tank body 110, an air supply pipe assembly 140 is connected to the side wall of the feed pipe 120, the air supply pipe assembly 140 is used to connect to an air supply source (i.e., an air supply device), and the other end of the air supply pipe assembly 140 is connected to a spray gun 130, a discharge pipe 150 is connected to the bottom of the tank body 110, the discharge pipe 150 is connected to the side wall of the air supply pipe assembly 140, a feed hopper 160 is connected to the top of the feed hopper 160, and a telescopic bellows 170 is connected to the top of the feed hopper 160.

[0028] In this embodiment, the tank body 110 is integrated with the air supply pipe assembly 140 and the spray gun 130, which can be used independently and do not need to be fixed in a specific position. Therefore, the volume of the tank body 110 can be reduced to reduce space occupation. When in use, the entire device is moved to the vicinity of the position to be cleaned, and the spray gun 130 can be arbitrarily aimed at the position to be cleaned. Sand or steel balls are added to the feed hopper 160 and enter the tank body 110. The air supply source passes compressed gas into the air supply pipe assembly 140. A part of the compressed gas enters the feed pipe 120 and the tank body 110 to push the sand or steel balls out of the discharge pipe 150 and into the air supply pipe assembly 140, and the other part of the compressed gas is discharged from the discharge pipe 150. The gas enters the air supply pipe assembly 140 to push the sand or steel shot entering the air supply pipe assembly 140 toward the spray gun 130, thereby ejecting the sand or steel shot from the spray gun 130 at high speed for cleaning operations. Since the tank body 110 is independent, after moving to different positions, the feed hopper 160 may be far away from the sand supply device. Therefore, a telescopic bellows 170 that can be freely extended and retracted at different angles is used to connect the discharge port of the sand supply device (not shown in the figure), which provides feasibility for mobile use, thereby ensuring that the device of this embodiment can be used normally after being moved, and is suitable for operations in narrow spaces.

[0029] As an optional embodiment, the air supply pipe assembly 140 includes a main air intake pipe 141 connected to the side wall of the feed pipe 120, the other end of the main air intake pipe 141 is used to connect to the air supply source, the side wall of the main air intake pipe 141 is connected to a booster air pipe 142, the other end of the booster air pipe 142 is connected to the spray gun 130, and the discharge pipe 150 is connected to the side wall of the booster air pipe 142.

[0030] In this embodiment, after compressed gas is introduced into the main air inlet pipe 141, the sand in the feed pipe 120 can be pushed quickly into the tank body 110, and then discharged from the discharge pipe 150 into the booster air pipe 142. At the same time, a part of the compressed gas enters the booster air pipe 142 to push the sand in the booster air pipe 142 to the spray gun 130, thereby realizing the sandblasting operation. Here, only one main air inlet pipe 141 is used for multi-pipeline feeding, and there is no need to set up multiple air inlet pipes separately, which reduces the pipeline layout, makes the device more concise, and further improves the applicability of operations in narrow spaces.

[0031] As an optional embodiment, the spray gun 130 includes a spray head 131 connected to the booster air pipe 142 , a pneumatic switch 132 is provided on the spray head 131 , and the pneumatic switch 132 is connected to a strip nozzle 133 .

[0032] In this embodiment, during sandblasting, the pneumatic switch 132 is turned on, and sand enters the nozzle 131. With the help of compressed gas, the sand can be ejected out of the strip nozzle 133 at high speed. Here, the strip nozzle 133 is a slender tube that can penetrate into complex cavities such as molds, which can further improve the operation requirements in narrow spaces.

[0033] As an optional implementation, a side wall of the main air intake pipe 141 is further connected to a jet pipe 143 , and the other end of the jet pipe 143 is connected to the nozzle 131 .

[0034] In this embodiment, due to the use of a slender strip nozzle 133, relying solely on the booster air pipe 142 to provide the sand with a jet force may result in insufficient jet force, resulting in a poor sandblasting cleaning effect. Therefore, the air jet pipe 143 is directly connected to the nozzle 131 to further provide a booster jet force to the sand in the nozzle 131, thereby ensuring the sandblasting effect.

[0035] As an optional embodiment, the nozzle 131 is further connected to a loop air pipe 144 , the loop air pipe 144 is connected to a first control valve 145 , and the first control valve 145 is connected to the side wall of the main air inlet pipe 141 .

[0036] In this embodiment, in order to prevent the inside of the nozzle 131 from being too large, the excess compressed gas is recovered to the main air intake pipe 141 through the loop air pipe 144, so that the compressed gas can be recycled, which has the effect of energy saving and emission reduction. When the gas needs to be recovered, the first control valve 145 can be opened. A pressure gauge can be set at the nozzle 131 to detect the air pressure status, and a controller can also be configured. The pressure gauge and the first control valve 145 are electrically connected to the controller to realize automatic control of the air pressure, which is more convenient to use.

[0037] As an optional embodiment, a one-way valve 146 is provided at the connection position between the main air intake pipe 141 and the side wall of the feed pipe 120, a second control valve 180 is provided on both the feed pipe 120 and the discharge pipe 150, and a third control valve 147 is provided at the connection position between the booster air pipe 142 and the side wall of the main air intake pipe 141.

[0038] In this embodiment, by coordinating the opening and closing of the one-way valve 146, the second control valve 180 and the third control valve 147, the operation of each pipeline can be opened or closed as needed, which makes the use more flexible.

[0039] As an optional embodiment, a plurality of support frames 190 are provided on the side wall of the tank body 110 , and the height of the support frames 190 at the connection positions on the side wall of the tank body 110 is adjustable.

[0040] In this embodiment, since the spray gun 130 needs to be aimed at the position to be cleaned during use, there may be a situation where the initial height of the spray gun 130 and the height difference between the position to be cleaned are large. At this time, the spray gun 130 needs to be held by hand to the position to be cleaned, which causes the pipe connected to the spray gun 130 to bend more and affects the transportation of sand in the pipe. Therefore, this embodiment can adjust the height of the connection position of the support frame 190 on the side wall of the tank body 110 according to the position to be cleaned, so that the initial height of the spray gun 130 can be flexibly adjusted according to the use environment, so as to facilitate the subsequent parallel alignment of the spray gun 130 with the position to be cleaned. The pipelines are relatively straight, which reduces the large bending of the pipeline caused by the large height difference between the initial height of the spray gun 130 and the position to be cleaned, thereby affecting the transportation of sand in the pipeline, thereby ensuring the sandblasting effect.

[0041] As an optional embodiment, the side wall of the tank body 110 is provided with multiple vertically arranged guide rails 210, the support frame 190 is slidably connected to the corresponding guide rails 210, and a limiting structure is provided between the support frame 190 and the tank body 110 to fix the support frame 190 at the corresponding height position of the tank body 110.

[0042] In this embodiment, when adjustment is required, the support frame 190 is slid along the guide rail 210 to the corresponding height, and then the support frame 190 is fixed at the corresponding height position of the tank body 110 through the limiting structure. At this time, the overall height of the tank body 110 relative to the ground changes, causing the horizontal height of the pipeline below the discharge pipe to change accordingly. It should be noted that the limiting structure here can ensure the fixing pin set on the support frame 190 and the multiple positioning holes that cooperate with the fixing pin. The multiple positioning holes are arranged along the height length of the guide rail 210. The limiting structure here can also adopt other applicable structures and should not be limited here.

[0043] As an optional embodiment, the support frame 190 includes a connecting frame 191 slidably connected to the guide rail 210, a bracket 192 is hinged at the bottom of the connecting frame 191, the bottom of the bracket 192 is connected to a floor 193, and fastening screws 194 are provided on the floor 193.

[0044] In this embodiment, the bracket 192 can be rotated to fit against the outer wall of the tank body 110 and can be folded and stored for easy transportation or storage. When needed, the bracket 192 is unfolded so that the floor 193 is parallel to the ground, and then the fastening screws 194 are screwed into the reserved holes in the ground or base plate to secure the bracket 192. It should be noted that the bracket 192 and the connecting frame 191 can be hinged with damping, and their unfolding angle can be set within a certain range.

[0045] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
