Description
Technical Field
[0001] The utility model belongs to the field of sandblasting machines, and more specifically, particularly relates to a sandblasting machine capable of recycling blasting materials. Background Art
[0002] Before we use steel, we need to go through preparation steps such as rust removal and grinding to remove the rust and oxide layer on the surface of the steel. The sandblasting machine we use now is fully capable of this job. Not only that, the steel surface treated with a slightly larger mesh number of spray will also form a certain degree of roughness and concave-convex texture, which helps to improve the adhesion with other materials and the adhesion of the coating, thereby improving the quality of subsequent painting, plating or welding processes. However, most manual sandblasting machines are used outdoors, and because the sandblasting machine uses a strong airflow to drive the spray to hit the steel surface to remove impurities on the steel surface, the staff needs to wear protective clothing and masks, and need to replenish the spray in time.
[0003] Based on the above, the inventors have found the following problems: the traditional sandblasting machine will generate a large amount of dust due to its working principle, which will cause harm to the human respiratory system, and because it is used outdoors, the spray material will fly everywhere due to the spraying, making it difficult to recycle and increasing the production cost. In addition, due to the hot weather, the workers still need to wear protective clothing and masks, which shortens the working time and reduces the efficiency of processing workpieces.

DETAILED DESCRIPTION
[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0025] Example:
[0026] As attached Figure 1 To Attachment Figure 6 As shown:
[0027] The utility model provides an energy-saving green steel product surface strong spraying equipment, including a body frame 1, a feeding hopper 2, and an air compressor 5. The feeding hopper 2 is provided on the top of the body frame 1, and an air compressor 5 is installed at the right position of the middle part of the body. A vertical auger conveyor 6 is installed on the left side of the body frame 1. The top of the vertical auger conveyor 6 is connected to the feeding hopper 2, and the bottom end of the vertical auger conveyor 6 is connected to a return bin 7. Through the coordinated use of the feeding hopper 2, the vertical auger conveyor 6 and the return bin 7, the screened spray material is conveyed to the feeding hopper 2 through the vertical auger conveyor 6, so that the automatic recycling of the spray material is realized without the need for manual repeated addition of the spray material, thereby improving the working efficiency. The spray material recovery module 3 is installed in the middle part of the body frame 1, and the spray material screening module 4 is installed at the bottom of the body frame 1. One end of the combined pipeline 8 is respectively connected to the spray material recovery module 3, the spray material screening module 4 and the air compressor 5, and the spray gun 9 is connected to the other end of the combined pipeline 8.
[0028] The spray recovery module 3 includes an upper shell 301, a return port 302, a blower 303, an air filter 304, a gas pipeline 305, a storage bin 306, a pressure sensor 307, a bottom baffle 308, a spur rack 309, and a drive motor 310. The return port 302 is opened on the top of the upper shell 301, and a blower 303 is installed on the left side of the upper shell 301. The blower 303 is the main power for the machine to realize waste suction. A pair of air filters 304 are symmetrically installed inside the upper shell 301. The upper shell 301 is provided with an air filter 304, and a gas pipeline 305 is arranged inside the upper shell 301.

By using the horizontal vibration motor 403, the vertical auger conveyor 6 and the pressure sensor 307 in coordination, the horizontal vibration motor 403 and the vertical auger conveyor 6 are in standby state when there is no signal from the pressure sensor 307, thereby saving electricity and reducing production costs.

The sprayed frosting is recovered through the suction port to achieve the effect of no dust and no flying sand during operation, ensure the health of the operators and improve the working comfort of the operators. Through the coordinated use of valve 1 906, valve 2 908 and valve 3 909, the suction flow, sandblasting flow and high-pressure gas flow can be controlled respectively, so as to better control the processing accuracy, save the spraying material, and thus improve the surface treatment effect of the workpiece and reduce the production cost.
[0032] The specific usage and function of this embodiment are as follows:
[0033] First, add a proper amount of spray material into the feeding hopper 2, then power on the machine, turn on the switch of the air compressor 5 to inflate the air cylinder of the air compressor, and then turn on the power switches of the vertical auger conveyor 6, the blower 303, and the horizontal vibration motor 403 respectively. When the pressure of the air compressor 5 is sufficient, pick up the spray gun 9 and place the spray gun 9 vertically close to the surface of the steel material to be worked on. At this time, open valve 1 906 to form a negative pressure between the spray gun 9 and the working surface, and then open valve 2 908 and valve 3 909 to start the operation. When the sandblasting recovery reaches a certain weight, the pressure sensor 307 will drive the motor 31 0 and the horizontal vibration motor 403 send an electrical signal, the drive motor 310 and the horizontal vibration motor 403 start working, and at the same time transmit the electrical signal to the vertical auger conveyor 6, the vertical auger conveyor 6 starts working synchronously, and the borax recovery and reuse is completed.
