DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] like Figure 1-6 As shown, one embodiment of the utility model discloses a sandblasting device for a variable frequency power-saving control cabinet, comprising a sandblasting cabinet 1, a mounting beam 10 is fixedly arranged at the upper end of the interior of the sandblasting cabinet 1, a mounting frame is arranged below the mounting beam 10, a plurality of nozzles 12 for sandblasting are fixed on the mounting frame, an air supply and exhaust joint 13 is installed on the outer side of the nozzle 12, the air supply and exhaust joint 13 is threadedly connected to the nozzle 12, a soft diaphragm 14 is arranged inside the nozzle 12, and the soft diaphragm 14 is anchored and connected to the nozzle 12;

[0027] It should be noted that all the nozzles in this embodiment are connected to the container for storing the blasting material required for sandblasting through a connecting pipe. The blasting material in the container for storing the blasting material is extracted from the container by a power device and enters each nozzle through the connecting pipe for spraying, thereby realizing the sandblasting operation.

[0028] Through the above arrangement, this embodiment can realize that the soft diaphragm is squeezed by filling the nozzle with gas through the air supply and exhaust interface, thereby compressing the channel for conveying electrophoretic paint inside the nozzle, increasing the pressure, increasing the flow rate, and reducing the amount of sandblasting; and after extracting the internal air of the nozzle through the air supply and exhaust interface, the channel for conveying electrophoretic paint inside can be expanded, reducing the pressure, reducing the spraying speed, and increasing the flow rate. Thus, the flow rate of the spray material is changed by changing the channel for conveying the spray material inside the nozzle, avoiding the occurrence of uneven sandblasting when sandblasting the cabinet panel of the variable frequency power saving control cabinet, and improving the quality of sandblasting.

[0029] The outer walls of the lower ends of both sides of the sandblasting cabinet 1 are provided with dust collecting components 2, and the interiors of the two side walls of the sandblasting cabinet 1 are provided with dust collecting grooves 20, and the inner walls of the dust collecting grooves 20 are embedded with dust collecting pipes 21; a negative pressure drainage component 22 is provided above the dust collecting grooves 20; the bottom of the dust collecting pipe 21 is connected to the dust collecting component 2, and the top of the dust collecting pipe 21 is connected to the negative pressure drainage component 22.

For these particulate dust, the negative pressure fan can be started, and the negative pressure fan generates negative pressure when working, so that the particulate dust inside the sandblasting cabinet is sucked into the U-shaped tube. Because the U-shaped tube is connected to the dust collecting pipe, this part of the particulate dust then moves into the dust collecting pipe, and then this part of the particulate dust enters the dust collecting box in the dust collecting component. Water for absorbing these particulate dust is placed in the dust collecting box in advance, which can effectively absorb these particulate dust, thereby improving the dust removal performance of the sandblasting device of the present embodiment.

[0031] In this embodiment, the dust collecting assembly 2 includes a dust collecting box 23, the bottom of the dust collecting pipe 21 is inserted into the dust collecting box 23, and the dust collecting box 23 is provided with water.

[0036] Through the above arrangement, this embodiment can achieve that when the sandblasting cabinet is working, some dust generated inside the sandblasting cabinet is guided into the U-shaped tube by the negative pressure fan, and then flows from the U-shaped tube to the dust collecting tube. A mesh cover is provided to block the spray material sprayed from the nozzle to prevent the spray material from entering the negative pressure fan and causing damage to the negative pressure fan.

[0037] In this embodiment, a second through hole 4 is provided on the surface of the sandblasting cabinet 1 on one side of the dust collecting groove 20 , and both ends of the U-shaped tube 27 are connected to the first through hole 28 and the second through hole 4 respectively.

[0038] Through the above arrangement, the present embodiment can achieve the effect of connection through the U-shaped tube, so that the particle dust inside the sandblasting cabinet can enter the dust collecting tube along the U-shaped tube and then enter the dust collecting box.

[0039] In this embodiment, the mounting frame includes a circular frame 110, and two mutually perpendicular square frames 111 are arranged in the middle of the circular frame 110, and both ends of the two square frames 111 are fixedly connected to the inner side wall of the circular frame 110; the two square frames 111 are fixedly connected at the intersection position;

[0043] In this embodiment, a rotating shaft 30 is fixedly connected at the place where the two square frames 111 are fixed to each other. The upper end of the rotating shaft 30 is connected to the output shaft of a driving motor 31 through a coupling. The driving motor 31 is fixed to the bottom of the mounting beam 10.

[0044] In this embodiment, the mounting frame of the above structure is provided and the nozzle is fixedly provided on the mounting frame of the above structure, so that the sandblasting covers a wider range.

[0045] The above arrangement of this embodiment can realize that by starting the driving motor, the power output shaft of the driving motor rotates to drive the rotating shaft to rotate, thereby driving the overall mounting frame to rotate, so that the nozzles fixed on the mounting frame can rotate, further increasing the range covered by the sandblasting, and then further improving the efficiency of the sandblasting. Thereby, the spray material sprayed by the nozzle can be sprayed onto the cabinet board of the variable frequency power saving control cabinet in a more comprehensive manner.
