Abstract

This utility model discloses a water-sand mixing sandblasting machine, including a support frame with a grinding fluid tank and a sandblasting tank on the support frame. The grinding fluid tank contains a grinding fluid pump, and the sandblasting tank contains a spray gun and gloves. The inlet of the grinding fluid pump is located at the bottom of the grinding fluid tank. The grinding fluid pump has a grinding fluid delivery port and at least one grinding fluid backflushing port. The grinding fluid delivery port is connected to the spray gun through a first pipe to supply grinding fluid to the spray gun. The grinding fluid backflushing port delivers grinding fluid to the bottom of the grinding fluid tank through a second pipe to make the grinding fluid at the bottom of the grinding fluid tank more uniformly mixed. This sandblasting machine delivers grinding fluid to the spray gun through the grinding fluid delivery port and simultaneously delivers grinding fluid to the bottom of the grinding fluid tank through the grinding fluid backflushing port to backflush the grinding fluid tank, causing the abrasive and liquid to flow and preventing the abrasive from settling to the bottom. This results in a more uniform mixing of the abrasive and liquid, ensuring that the mixing ratio of abrasive and liquid is within a predetermined range.

Description

Technical Field

[0001] This utility model relates to the field of sandblasting equipment technology, specifically to a water-sand mixed sandblasting machine. Background Technology

[0002] A water-sand blasting machine uses a mixture of abrasive (such as brown corundum, glass beads, etc.) and liquid (such as water) as the medium, and external compressed air as the power source to perform blasting processing on the surface of solid workpieces. Its working principle is as follows: Abrasive and liquid are mixed in a specific ratio. A slurry pump supplies the abrasive slurry (the mixture of abrasive and liquid) to the blasting gun. Compressed air is used to accelerate the slurry. After entering the blasting gun through an air supply pipe, the compressed air accelerates the slurry within the blasting gun and ejects it through the nozzle, thus spraying the slurry onto the surface of the workpiece to achieve the desired processing purpose.

[0003] However, since the density of abrasive is greater than that of liquid, abrasive tends to settle at the bottom of the grinding fluid chamber. Therefore, when the inlet of the abrasive pump is at the bottom of the grinding fluid chamber, the proportion of abrasive in the sprayed grinding fluid is relatively large, while when the inlet of the abrasive pump is in the middle of the grinding fluid chamber, the proportion of abrasive in the sprayed grinding fluid is relatively small. This makes the mixing ratio of abrasive and liquid prone to change, thus affecting the processing effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water-sand mixing blasting machine that can make the abrasive and liquid mix more evenly.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A water-sand mixing sandblasting machine includes a support frame, on which a grinding fluid chamber and a sandblasting chamber are provided. The grinding fluid chamber is equipped with a grinding fluid pump, and the sandblasting chamber is equipped with a spray gun and gloves. The feed inlet of the grinding slurry pump is located at the bottom of the grinding slurry tank, and the grinding slurry pump is provided with a grinding slurry delivery port and at least one grinding slurry backflushing port. The grinding fluid delivery port is connected to the spray gun through a first pipe to supply grinding fluid to the spray gun; The grinding fluid backflushing port delivers grinding fluid to the bottom of the grinding fluid tank through a second pipe, so that the grinding fluid at the bottom of the grinding fluid tank is more evenly mixed.

[0006] As a further improvement to the above technical solution: the grinding pump is provided with a limiting plate, the limiting plate is provided with a limiting hole, the liquid outlet end of the second pipe extends into the limiting hole and discharges liquid downwards.

[0007] As a further improvement to the above technical solution: two grinding fluid backflushing ports are provided, and the two grinding fluid backflushing ports face the two sides of the grinding fluid tank respectively.

[0008] As a further improvement to the above technical solution: the grinding fluid pump is provided with a four-way connector, and the grinding fluid delivery port and the grinding fluid backflushing port are both located on the four-way connector.

[0009] As a further improvement to the above technical solution: the sandblasting chamber includes a chamber body, a chamber cover and a telescopic rod, the chamber cover is hinged to the chamber body, the telescopic rod is located between the chamber cover and the chamber body, the glove is located on the chamber cover, and the chamber cover is provided with an observation window.

[0010] As a further improvement to the above technical solution: the bottom of the chamber is a perforated plate, which is used to allow the grinding fluid to flow into the grinding fluid chamber.

[0011] As a further improvement to the above technical solution: the bottom of the grinding fluid chamber is provided with a grinding fluid outlet.

[0012] As a further improvement to the above technical solution, it also includes a control module and a foot switch. The control module is located on the top of the sandblasting chamber, and the foot switch is electrically connected to the control module.

[0013] As a further improvement to the above technical solution, it also includes a signal indicator light and an emergency stop button, both of which are electrically connected to the control module.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The water-sand mixing sandblasting machine disclosed in this utility model supports the grinding fluid tank and the sandblasting tank with a bracket. The grinding fluid is delivered by the grinding fluid pump and sprayed out by the spray gun. Gloves are provided for easy operation by the operator. During sandblasting, the grinding fluid is delivered to the spray gun through the grinding fluid delivery port and simultaneously delivered to the bottom of the grinding fluid tank through the grinding fluid backflushing port to backflush the grinding fluid tank, so that the abrasive and liquid flow together and the abrasive settles to the bottom. This makes the mixing of abrasive and liquid more uniform and ensures that the mixing ratio of abrasive and liquid is within a predetermined range. This equipment does not generate dust during sandblasting, which can effectively solve the problem of dust pollution to the air during sandblasting. It is especially suitable for workpieces with oily dirt on the surface.

The slurry delivery port 42 is connected to the spray gun 50 through the first pipe 44 to supply slurry to the spray gun 50; The grinding fluid backflushing port 43 delivers grinding fluid to the bottom of the grinding fluid tank 20 through the second pipe 45, so as to make the grinding fluid at the bottom of the grinding fluid tank 20 more uniformly mixed.

[0024] This water-sand blasting machine supports the slurry tank 20 and the blasting tank 30 via a bracket 10. Abrasive slurry is pumped in by a slurry pump 40 and sprayed out by a spray gun 50. Gloves 60 facilitate operation. During blasting, slurry is supplied to the spray gun 50 through the slurry inlet 42 and simultaneously supplied to the bottom of the slurry tank 20 through the slurry backflushing inlet 43. This backflushing of the slurry tank 20 promotes the flow of abrasive and liquid, preventing abrasive from settling to the bottom and ensuring a more uniform mixing ratio. The equipment does not generate dust during blasting, effectively solving the problem of dust pollution during blasting. It is particularly suitable for workpieces with oily surfaces.

[0025] In this embodiment, the grinding slurry pump 40 is provided with a limiting plate 46, and the limiting plate 46 is provided with a limiting hole. The liquid outlet end of the second pipe 45 extends into the limiting hole and discharges liquid downwards. Specifically, the limiting hole limits and fixes the second pipe 45 to prevent the second pipe 45 from shifting, thereby further ensuring the backflushing effect.

[0026] In this embodiment, two grinding fluid backflushing ports 43 are provided, with the two ports facing opposite sides of the grinding fluid tank 20. Specifically, by providing two grinding fluid backflushing ports 43, the backflushing effect can be further guaranteed, making the abrasive and liquid mix more evenly. In other embodiments, the position and number of grinding fluid backflushing ports 43 can be changed to achieve the same effect.

[0027] In this embodiment, the grinding fluid pump 40 is provided with a four-way connector 47, and both the grinding fluid delivery port 42 and the grinding fluid backflushing port 43 are located on the four-way connector 47. Specifically, the four-way connector 47 facilitates disassembly, assembly, and maintenance.

[0028] In this embodiment, the sandblasting chamber 30 includes a chamber body 31, a chamber cover 32, and a telescopic rod 33. The chamber cover 32 is hinged to the chamber body 31, the telescopic rod 33 is located between the chamber cover 32 and the chamber body 31, and a glove 60 is mounted on the chamber cover 32. The chamber cover 32 is provided with an observation window 321. Specifically, the chamber cover 32 facilitates the loading and unloading of workpieces, and the observation window 321 on the glove allows the operator to observe the workpiece processing.

[0029] In this embodiment, the bottom of the chamber 31 is a perforated plate 311, which allows the grinding fluid to flow into the grinding fluid chamber 20. Specifically, the grinding fluid sprayed from the spray gun 50 can flow into the grinding fluid chamber 20 through the perforated plate 311, thus allowing for repeated use.

[0030] In this embodiment, the bottom of the grinding fluid tank 20 is provided with a grinding fluid outlet 21. Specifically, after use, the grinding fluid outlet 21 can be opened to discharge the grinding fluid for cleaning the machine or replacing it with new grinding fluid.

[0031] This embodiment also includes a control module, a foot switch 70, an indicator light 80, and an emergency stop button 90. The control module is located on the top of the sandblasting chamber 30. The foot switch 70 is electrically connected to the control module, and both the indicator light 80 and the emergency stop button 90 are electrically connected to the control module. Specifically, the control module is preferably a microcontroller. The control module controls each component. The foot switch 70 facilitates the operator to turn the equipment on and off. The indicator light 80 includes equipment start / stop lights, status lights, etc., to facilitate observation of the equipment's operating status. The emergency stop button 90 can be used in emergencies to improve equipment safety. The connection and control relationships between the microcontroller and the indicator light 80 and the emergency stop button 90 are existing technologies and will not be described in detail here.

[0032] In this embodiment, a function switch 91 and a window cleaning switch 92 are also included. Both the function switch 91 and the window cleaning switch 92 are electrically connected to the control module. The function switch 91 is equipped with an LED light. When the function switch 91 is turned on, the LED light is lit. At this time, pressing the foot switch 70 will perform sandblasting. When the function switch 91 is turned off, the LED light is turned off. At this time, pressing the foot switch 70 will only perform air cleaning without sandblasting. The sandblasting chamber 30 is also equipped with a nozzle (not shown in the figure) for blowing air onto the observation window 321. When the window cleaning switch 92 is turned on, the observation window 321 can be cleaned by blowing air. The connection and control relationship between the microcontroller function switch 91 and the window cleaning switch 92 are existing technologies and will not be described in detail here.
