[0002] In the processing of metal castings, as a commonly used surface treatment technical equipment, sandblasting machines are widely used to remove impurities such as oxide scales, rust, and oil stains on the surface of castings, and to improve the surface roughness and smoothness of castings. However, traditional sandblasting machines have significant environmental protection problems in actual applications.

[0003] Firstly, a large amount of dust is generated during the operation of traditional sandblasting machines. These dusts not only pollute the operation environment, but also pose a serious threat to human health. Since people and castings operate in the same space, it is difficult for operators to avoid close contact with sand dust. Working in such an environment for a long time may cause health problems such as respiratory diseases.

[0004] Secondly, sand dust and people are in the same space, resulting in low efficiency of sand dust removal. Traditional sandblasting machines lack an efficient dust removal system, making it difficult for sand dust to be quickly discharged, further exacerbating environmental pollution and the health risks of operators.

[0005] Therefore, in view of the deficiencies of the existing technology, it is necessary to improve the sandblasting machine to reduce the amount of dust generated during its operation and improve the efficiency of sand dust removal, thereby protecting the environment and the health of operators.

Detailed implementation manners

[0023] To better understand the present utility model, the following will Figures 1 to 6 be combined to explain in detail the implementation manners of the present utility model.

[0024] It should be noted that the "front, rear, left, right, up, down" directions described in the text are all based on Figure 1 the "front, rear, left, right, up, down" directions in

[0025] Refer to Figure 1 , an environment-friendly casting sandblasting machine of the present utility model includes a closed box body 1. A funnel 2 is arranged at the bottom of the box body 1 for collecting the sand dust generated during the sandblasting process. The bottom of the funnel 2 is connected with a pneumatically controlled sandblasting three-way valve 3, and this valve can accurately control the sandblasting operation. One connection of the pneumatically controlled sandblasting three-way valve 3 is connected with an air pipe 4, and a pressure valve 5 is arranged at the end of the air pipe 4. The pressure valve 5 is connected to the air source by a pipeline, and this pressure valve 5 is used to adjust the air pressure during the sandblasting process. The second connection is connected with a sandblasting pipe 6 extending into the box body 1, and a sandblasting head 7 is installed at the end of the sandblasting pipe 6. The above structure constitutes a sandblasting system for sandblasting the casting.

[0026] As shown in Figure 2 , a feeding port 8 is opened on one side of the box body 1, and a box door 9 adapted to the feeding port 8 is equipped. A locking part 10 (preferably using a buckle) is arranged between the box door 9 and the box body 1 to ensure that the inside of the box body 1 is in a closed state during the sandblasting process, reducing the leakage of dust. A dust suction pipe 11 is arranged at the top of the box body 1 and is connected to an external dust removal device. The dust removal device and the dust suction pipe 11 constitute a dust suction system. During the sandblasting process, the dust suction system continuously works to suck the dust in the box body 1 into the dust removal device for treatment, ensuring the air quality in the box body 1. An operating platform 12 that slides towards the box door 9 is arranged inside the box body 1, facilitating the operator to move the casting during the sandblasting process. A sand leakage groove 13 is opened on the operating platform 12 to enable the sand dust to flow smoothly into the funnel 2. Slide rails are arranged on both sides at the bottom of the operating platform 12 and are matched with the supporting pulleys 22 on the wheel frames 21 on both sides of the inner wall of the box body 1 to realize the smooth sliding of the operating platform 12. The slide rails are made of C-shaped steel, and the open end thereof is butted against the supporting pulley 22.

[0027] In order to observe the sandblasting condition of castings, Figure 1 As shown in FIG, an observation window 14 is provided on the front of the box 1, allowing the operator to observe the sandblasting process without opening the box door 9. Two operation holes are provided below the observation window 14, and sandblasting gloves extending into the box 1 are provided, so that the operator can perform sandblasting operations while keeping the box 1 closed.

[0028] Considering that when spraying workpieces with regular and symmetrical shapes such as cylindrical castings, the position and angle of the sandblasting head 7 need to be frequently changed to complete the process, the efficiency is low. Figure 2 As shown in , a detachable turntable 16 is added to the operating table 12, and a rotating shaft 17 is provided at the bottom of the turntable 16. The bottom end of the rotating shaft 17 is rotatably connected to the base 18, and a slot is provided at the bottom of the base 18 to connect with the sand leakage groove 13, so as to facilitate the removal of the turntable 16, replacement and cleaning of the operating table 12. Figure 3 As shown in the figure, the operating table 12 has a disc as the axis and a ring as the outer ring. The disc and the ring are welded by an array of steel pipes. When sandblasting, sand particles can fall from the gaps of the steel pipes to prevent sand particles from accumulating on the turntable 16. A fixing rod 19 is set at the top of the inner wall of the box body 1. The fixing rod 19 is composed of a plurality of sections, and the sections are connected by universal joints to adapt to sandblasting operations at different angles. A clamping part 20 (preferably a spring clamp) is set at the end of the fixing rod 19 to fix the sandblasting head 7 instead of manual fixation.

[0029] like Figures 2 to 4 As shown in the figure, two mutually hinged operating tables 12 are arranged in the box 1, and a spring latch 27 is arranged between the two operating tables 12. By setting up tools such as a silent car in advance at the bottom, when it is necessary to load and unload workpieces, the box door 9 can be opened and the operating table 12 can be pulled outward. When the hinge point extends out of the opening, the locking state of the operating table 12 is released by pulling the spring latch 27. The outer operating table 12 loses the support of the support pulley 22 and flips down onto the silent car, thereby forming a slope, so as to facilitate the use of the slope for loading and unloading parts. Press plates 23 are arranged on both sides of the inner wall of the box 1 to provide support when the operating table 12 is unfolded to ensure operational stability.

[0030] like Figure 2 and Figure 6 As shown in the figure, a sleeve 24 adapted to the sandblasting tube 6 is arranged on the top of the box body 1, and fixed bristles 25 are arranged on the inner wall of the sleeve 24. The fixed bristles 25 can not only be used to support the sandblasting tube 6 in the sleeve 24, but also to remove residual sand and dust on the tube when the sandblasting tube 6 is extended or retracted.

[0031] like Figure 1 and Figure 2 As shown in , in order to improve the smoothness of the sandblasting tube 6 when it is pulled out, a pulley frame 26 adapted to the sandblasting tube 6 is set on the top of the box body 1.

[0032] Usage method and principle of the utility model:

[0033] First, carry out preparatory work. Check whether the sandblasting machine is in a normal working state, and ensure that the dust collection system, sandblasting system, etc. are all connected and can work normally.

[0034] Then, place the casting to be processed on the operating table 12, open the pneumatic control sandblasting three-way valve 3, and adjust the pressure valve 5 at the end of the air pipe 4 to set an appropriate sandblasting air pressure. Select a suitable sandblasting head 7 according to the material and surface condition of the casting, and fix it on the clamping part 20 of the fixing rod 19. Observe the position of the sandblasting head 7 through the observation window 14 to ensure that it maintains an appropriate distance and angle from the casting.

[0035] Next, after ensuring that the casting is placed stably, close the box door 9 to prevent dust leakage during sandblasting. Turn on the switch (power switch) of the sandblasting system to start the sandblasting operation. At the same time, turn on the external dust removal equipment to ensure that the dust collection system can smoothly suck in and process the dust. During the sandblasting process, the sandblasting head 7 can be finely adjusted outside the box body 1 through the sandblasting gloves to achieve the best sandblasting effect.

[0036] After that, during the sandblasting process, it is necessary to continuously monitor the sandblasting situation. Observe the changes on the surface of the casting through the observation window 14, and pay attention to whether there are any abnormal situations, such as blockage of the sandblasting head 7, displacement of the casting, etc. If an abnormal situation is found, the sandblasting operation should be stopped immediately, and corresponding measures should be taken for treatment.

[0037] Finally, when the surface of the casting reaches the expected treatment effect, turn off the switch of the sandblasting system to stop the sandblasting operation. Wait for a period of time to let the dust collection system continue to work for a while to ensure that the dust in the box body 1 is completely removed. Then, open the box door 9, and use the sandblasting gloves or special tools to take out the processed casting from the operating table 12. If there is residual sand and dust on the operating table 12, it can be moved to the lower part of the funnel 2 through the sliding operating table 12 for cleaning. After taking out and cleaning the casting, clean and maintain the entire sandblasting machine to keep the equipment clean and in good condition.

[0038] Through the above steps, the environmentally friendly casting sandblasting machine of the present invention can be used for sandblasting treatment of castings safely, efficiently and environmentally friendly.
