Description

Technical Field

[0001] This utility model relates to the field of high-pressure water blasting technology, specifically a high-pressure water blasting cleaning device. Background Technology

[0002] Water jetting is a technique that uses a high-speed jet formed by mixing water and sand to treat the surface of an object. Water and sand are mixed in a certain proportion, and the mixture is propelled at high speed by a high-pressure water pump and sprayed onto the surface of the object to be treated through a spray gun.

[0003] For example, a high-pressure water blasting cleaning device with authorization announcement number "CN207289840U" can immediately collect and use the blasted wet sand without further treatment, greatly reducing the difficulty of recycling the raw material used in the high-pressure water blasting cleaning device, namely the wet sand. At the same time, the sand content of the wet sand is much lower than that of dry sand. Traditional high-pressure water blasting devices usually transport water and sand in a fixed preset ratio. In use, the sand and water are simply mixed in a fixed mixing chamber and then sprayed directly. This design means that in actual use, regardless of the cleaning task, only a single ratio of water and sand mixture can be used. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional high-pressure water blasting devices can only use a single ratio of water and sand mixture regardless of the cleaning task, and proposes a high-pressure water blasting cleaning device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-pressure water jet sandblasting cleaning device is designed, comprising a base and a housing. The housing is fixedly connected to the upper end of the base, and the upper end of the housing is threadedly connected to the housing cover by bolts. The upper end of the housing cover is threadedly connected to a servo motor by bolts. Both sides of the inner wall of the housing cover are fixedly connected to the feed pipe. The lower end of the housing is fixedly connected to the discharge port. The upper end of the base is provided with a water jet sandblasting ratio changing structure. A shell is fixedly connected to the left side of the upper end of the base, and the interior of the shell is provided with a sand removal structure.

[0007] Preferably, the water jetting ratio changing structure includes a water tank and blocks. The lower end of the water tank is fixedly connected to the base, the right end of the water tank is fixedly connected to the first water pump, the end of the first water pump is fixedly connected to the water pipe, the end of the water pipe is fixedly connected to the tank body, the right end of the tank body is fixedly connected to multiple blocks, and the outer wall of the water pipe is fixedly connected to the blocks.

[0008] Preferably, the output shaft of the servo motor is fixedly connected to a stirring rod, and the outer wall of the stirring rod is rotatably connected to the box cover through a sealed bearing.

[0009] Preferably, the ends of the water tank and the discharge port are both fixedly connected to the discharge pipe.

[0010] Preferably, the sand removal structure includes a round rod, both ends of which are rotatably connected to the box and the base respectively via sealed bearings. Both sides of the outer wall of the round rod are rotatably connected to the shell via sealed bearings. The lower outer wall of the round rod is fixedly connected to a second bevel gear. The second bevel gear meshes with a first bevel gear. The rotating shaft of the first bevel gear is rotatably connected to the shell via a sealed bearing. The end of the rotating shaft of the first bevel gear is fixedly connected to a handle. The upper outer wall of the round rod is fixedly connected to the mesh box.

[0011] Preferably, the left end of the housing is fixedly connected to the second water pump.

[0012] The high-pressure water jet cleaning device proposed in this utility model has the following advantages: by changing the structure and the fit of the outlet by changing the water jet ratio, the water-sand mixture falls into the mesh box through the outlet. The size of the filter screen at the bottom of the mesh box is much smaller than the size of the sand, so the water flows through the mesh box into the water tank, while the sand remains in the mesh box. The first water pump causes the water in the water tank to flow back into the box through the water pipe, thereby reducing the proportion of sand and achieving the effect of changing the water-sand mixture ratio when the equipment is in use.

[0027] Working principle:

[0028] When using a high-pressure water jet cleaning device:

[0029] Feeding and mixing:

[0030] The operator pours the sand into the box 2 through the feed inlet 7 on the left side of the box cover 6 (e.g., Figure 2 Water is poured into the box 2 through the feed inlet 7 on the right side of the box cover 6. The external power supply of the servo motor 8 is connected and the servo motor 8 is started. The output shaft of the servo motor 8 rotates, which drives the stirring rod 9 to rotate. The rotation of the stirring rod 9 mixes the water and sand in the box 2. After observing that the water and sand are evenly mixed through the observation window at the front of the box 2, the servo motor 8 is turned off.

[0031] Water blasting operation:

[0032] Turn on the second water pump 12 and the sandblasting gun. The left end of the second water pump 12 is connected to the sandblasting gun through a pipe. The water and sand mixture is sprayed out through the sandblasting gun. The second water pump 12 can be a high-pressure plunger pump. Through the reciprocating motion of the plunger, low-pressure water is drawn in and compressed into high-pressure water for output. The second water pump 12 makes the water and sand mixture obtain high speed and spray it onto the surface of the object to be treated through the sandblasting gun. The high-speed water and sand jet relies on strong impact force to break and peel off dirt, rust, old coatings and other impurities on the surface of the object.

[0033] When cleaning lighter dirt or items requiring high surface precision, the proportion of abrasive needs to be reduced. In this case, the solenoid valve at the discharge port 10 is opened. The discharge port 10 contains a solenoid valve, allowing the water-abrasive mixture to fall into the mesh box 405 through the discharge port 10 (e.g., ...). Figure 2The size of the filter screen at the lower end of the mesh box 405 is much smaller than the size of the sand. Therefore, water flows through the mesh box 405 into the water tank 501, while the sand remains in the mesh box 405. When the first water pump 502 is turned on, the water in the water tank 501 flows back into the box 2 through the water pipe 503, thereby reducing the proportion of sand and achieving the effect of changing the water-sand mixture ratio when the equipment is in use.

[0034] After water blasting is completed, turn off all power, unscrew the bolts connecting handle 404 to housing 3, and rotate handle 404. The rotation of handle 404 will drive the first bevel gear 403 to rotate (e.g., Figure 3 The first bevel gear 403 rotates, driving the second bevel gear 402 to rotate. The second bevel gear 402 rotates, driving the round rod 401 to rotate. The round rod 401 rotates, driving the mesh box 405 to rotate 180 degrees, thus facilitating the operator to remove the sand from the mesh box 405. After the sand is removed, the mesh box 405 is reset by the handle 404, thus completing the working process of the high-pressure water sandblasting cleaning device. A maintenance door is installed at the front end of the shell 3, through which the operator can periodically inspect the equipment inside the shell 3.
