[0038] like Figure 1 As shown, the utility model provides a device for improving the sandblasting efficiency of a sandblasting machine, the device comprising:

[0039] The sand tank 100 is used to store steel sand, and a sand inlet 110 is arranged on the top of the sand tank 100.

[0040] At least one air storage bag 200 is used to store compressed air. The air storage bag 200 is connected to the sand tank 100 through a first pipeline 210 and communicates with the interior of the sand tank 100. At least one compressed air intake pipe 220 is connected to the air storage bag 200.

[0041] The abrasive valve 300 is disposed at the bottom of the sand pot 100 , and the abrasive valve 300 is connected to the air storage bag 200 through a second pipeline 310 .

[0042] The compressed air in the air storage bag 200 can be pressurized to the sand tank 100 through the first pipeline 210 to increase the pressure of the steel sand, thereby improving the sand feeding efficiency.

[0043] The compressed air in the air storage bag 200 can be pumped into the abrasive valve 300 through the second pipeline 310, so that the steel sand is sprayed out together with the compressed air, thereby increasing the sand discharge pressure.

[0044] The abrasive valve 300 includes a steel grit inlet, a compressed air inlet, and an outlet. The compressed air and the steel grit are ejected from the outlet of the abrasive valve 300 .

[0045] like Figure 1 As shown, as a preferred embodiment of the sandblasting efficiency improvement device of the present invention, a closing valve 120 is provided in the sand inlet 110 of the sand tank 100 , and the closing valve 120 is connected to the first pipeline 210 .

[0046] The compressed air supplied by the first pipeline 210 allows the closing valve 120 to press against the sand inlet 110 under the pressure of the compressed air, and the sand is not inletted at this time. When the sand is inletted, the compressed air is cut off, and the mushroom head valve returns to its original position, thereby starting to inlet the sand.

[0047] like Figure 1 As shown, as a preferred embodiment of the sandblasting efficiency improvement device of the sandblasting machine of the utility model, a first air inlet valve 211 and a one-way valve 212 are arranged on the first pipeline 210 .

[0048] Preferably, a first air intake valve 211 and a one-way valve 212 are sequentially arranged from the inlet to the outlet of the first pipeline 210 .

[0049] The state of the closing valve 120 inside the sand pot 100 is controlled by compressed air through the first air inlet valve 211 and the one-way valve 212 , so that the opening and closing of the sand inlet 110 can be automatically controlled.

[0050] like Figure 1 As shown, as a preferred embodiment of the sandblasting efficiency improvement device of the utility model, two compressed air intake pipes 220 are connected to the air storage bag 200, and the two compressed air intake pipes 220 are respectively arranged on the left and right sides of the air storage bag 200.

[0051] The air storage bag 200 adopts a two-side air intake method, which can reduce the air storage time and thus ensure the pressure requirement of the compressed air.

[0052] like Figure 1 As shown, as a preferred embodiment of the sandblasting efficiency improvement device of the present invention, the second pipeline 310 includes a plurality of pipelines arranged in parallel.

[0053] like Figure 1As shown, as a preferred embodiment of the sandblasting efficiency improvement device of the utility model, the second pipeline 310 is a wear-resistant high-pressure air pipe.

[0054] like Figure 1 As shown, as a preferred embodiment of the sandblasting efficiency improvement device of the sandblasting machine of the utility model, a second air inlet valve 311 is provided on the second pipeline 310 .

[0055] Compressed air is pumped into the abrasive valve 300 through the second air inlet valve 311, and the steel sand is ejected together with the compressed air, thereby increasing the sand discharge pressure.

[0056] like Figure 1 As shown, as a preferred embodiment of the sandblasting efficiency improvement device of the present invention, a material level meter 130 is arranged outside the sand tank 100 to display the steel sand material level.

[0057] As a preferred implementation of the device for improving the sandblasting efficiency of a sandblasting machine of the utility model, a plurality of sand guns are connected to the abrasive valve 300 .

[0058] The steps of using the preferred embodiment of the sandblasting efficiency improvement device of the utility model are as follows:

[0059] S1. First, the air storage bag 200 is stored with air through the dual compressed air inlet pipes 220 in the device to increase the compressed air pressure.

[0060] S2. The first air inlet valve 211 remains closed, and the closing valve 120 is open. The steel sand enters the sand tank 100 from the external sand bin.

[0061] S3. When the material level meter 130 shows that the steel sand material level reaches the standard, the first air inlet valve 211 is opened, the sealing valve 120 inside the sand tank 100 is in a closed state, and the steel sand stops entering.

[0062] S4, opening the first air inlet valve 211 to pressurize the steel sand in the sand pot 100.

[0063] S5. After pressurization, the abrasive valve 300 and the second air inlet valve 311 are opened, and the pressurized steel sand is mixed with the compressed air and ejected from the outlet of the abrasive valve 300, and the high-speed steel sand flows into the sand gun pipeline.

[0064] S6. Steel sand is sprayed out from the sand gun to polish the surface of the steel structure.

[0065] In summary, the sandblasting efficiency improvement device of the utility model solves the problem that the efficiency of the sandblasting machine cannot meet the production capacity requirements, and directly adding a sand gun, the sand feeding efficiency and the sand discharge pressure cannot meet the use requirements. The sandblasting efficiency improvement device of the sandblasting machine can ensure that the efficiency and pressure of the sandblasting can match after adding a sand gun at the bottom of the sand tank 100.
