[0038] Example

[0039] Please refer to Figure 1-Figure 7 The utility model provides a sandblasting room, including a supporting frame 1, a first sand blocking layer 2, a material detector 3, an angle adjustment structure 4, a second sand blocking layer 5, and a nozzle assembly 6.

[0040] Furthermore, the supporting frame 1 is located above the material to be sandblasted, supporting the entire sandblasting device.

[0041] The supporting frame 1 includes a gridded rectangular tube 101 .

[0042] A first sand-blocking layer 2 containing sand-blocking gas is disposed on the top of the rectangular tube 101. A material detector 3 and a nozzle assembly 6 are disposed at the bottom of the rectangular tube 101. Both the detector head of the material detector 3 and the nozzle of the nozzle assembly 6 are oriented toward the material to be sandblasted, enabling rapid material detection and sandblasting.

[0043] The material detector 3 is composed of a laser sensor, which detects whether there is material by emitting laser light and then detecting the presence of the material by the laser light reflected back after the laser light hits the material.

[0044] Among them, the nozzle assembly 6 is connected to the external sand storage tank through a pipe (the end of the pipe connected to the nozzle assembly is a hose, so that the pipe can be bent when the angle of the nozzle assembly changes). When the valve of the sand storage tank is opened, the sand in the tank is pumped into the pipe and sprayed out from the nozzle to sandblast the material to be sandblasted below. The interior of the square rectangular tube 101 is hollow, and the pipe is located in the hollow interior of the support rectangular frame 1 to protect the pipe.

[0045] It is worth noting that the structures and principles of the material detector 3 and the sand storage tank mentioned above are conventional technical knowledge that can be mastered by those skilled in the art and belong to the existing technology, so they will not be described in detail in this specification.

[0046] Furthermore, an angle adjustment structure 4 is provided at the bottom of the square rectangular tube 101, and the angle adjustment structure 4 is rotated by the motor inside it to adjust the angle. A plurality of nozzle assemblies 6 are provided on the angle adjustment structure 4, and a large amount of sand particles are sprayed through multiple nozzles to perform fast and effective sandblasting at multiple angles.

[0047] The angle adjustment structure 4 includes a first motor 401 and a mounting plate 402 .

[0048] The first motor 401 is arranged at the bottom of the square rectangular tube 101. The driving shaft of the first motor 401 is fixedly connected to one end of the mounting plate 402. The other end of the mounting plate 402 is rotatably mounted on the support seat. The support seat is fixed to the bottom of the square rectangular tube 101. Several nozzle assemblies 6 are fixedly arranged on the mounting plate 402.

[0049] A plurality of material detectors 3 are provided at the bottom of the square rectangular tube 101. When material to be sandblasted appears below it, it will be quickly detected by the material detector 3 on it. According to the detection signals of the material detectors 3 at different plane positions, the specific size range of the material to be sandblasted below is judged. At this time, the detection signal of the material detector 3 is transmitted to the control terminal through the line. The control terminal drives the nozzle assembly 6 to rotate through the program control angle adjustment structure 4, so that the nozzle is directed to the range position of the material to be sandblasted, and accurate sandblasting is performed to improve the sandblasting efficiency.

[0050] In addition, a plurality of angle adjustment structures 4 are provided at the bottom of the lattice rectangular tube 101 along the left and right lateral directions, which are located in the middle of the lattice rectangular tube 101, and a plurality of angle adjustment structures 4 are provided at the bottom of the lattice rectangular tube 101 along the front and rear lateral directions, which are located at both ends of the lattice rectangular tube 101. The angle adjustment structures 4 in the two directions are not staggered, but the directions of their angle adjustments are staggered. While increasing the number of nozzle assemblies 6, the angle coverage range of the nozzle assemblies 6 is also increased, thereby avoiding the nozzle assemblies 6 from having a dead angle in the sandblasting of the material to be sandblasted below.

[0051] Furthermore, a first sand blocking layer 2 is provided above the square rectangular tube 101 , and the first sand blocking layer 2 includes an air storage box 201 , an inclined bottom shell 202 , an air outlet 203 , an air inlet 204 , a support column 205 , a cylinder 206 , and a plug plate 207 .

[0052] An air storage box 201 is provided above the square rectangular tube 101. The outer shape of the air storage box 201 is rectangular, and the interior of the air storage box 201 is hollow. The top of the air storage box 201 is connected to an air inlet 204. The air inlet 204 is provided with a pump (the pump is a conventional technology that can be mastered by people in this field, not shown in the figure), which pumps the sand-blocking gas into the air storage box 201 for storage and increases the air pressure in the air storage box 201. An air outlet 203 is provided at the bottom of the air storage box 201, and the sand-blocking gas is sprayed into the outside of the material to be sandblasted below through the air outlet 203 to block the sand particles and accompanying material debris splashed out during sandblasting.

[0053] The bottom of the gas storage box 201 is an inclined bottom shell 202 , and the inclined bottom end of the inclined bottom shell 202 is close to the gas outlet 203 , so that the sand-blocking gas can flow into the gas outlet 203 through the inclined bottom shell 202 .

[0054] The air outlet 203 is a square ring-shaped air outlet formed along the outer wall of the lower end of the air storage box. The blasting material is covered by the ground projection of the air outlet 203.

[0055] The bottom of the inclined bottom shell 202 is connected to the top of the support column 205, and the bottom of the support column 205 is connected to the top of the rectangular tube 101, thereby fixing the entire first sand-blocking layer 2 and the rectangular tube 101 together. The support frame 1 also includes a rectangular tube frame 102, which is fixed to the outside of the gas storage box 201 and symmetrically arranged on both sides of the gas storage box 201. The rectangular tube frame 102 can be installed and fixed to the top of a building.

[0056] A plug plate 207 of matching shape is vertically slidably provided at the air outlet 203. The plug plate 207 has sealing properties and can seal the air outlet 203 to prevent the sand-blocking gas in the material box from leaking out of the air outlet 203 at will. The plug plate 207 is connected to the push rod of the cylinder 206. The cylinder 206 is fixed on the material box, and the push rod passes through the material box.

[0057] Preferably, when the material detector 3 detects the material to be sandblasted below, the nozzle assembly 6 starts sandblasting, and the cylinder 206 drives the plug plate 207 to move upward, opening the air outlet 203, so that the high-pressure sand-blocking gas in the air storage box 201 is sprayed from the rectangular air outlet 203 to the outside of the material to be sandblasted below. The sand-blocking gas forms a vertically downward rectangular "air wall" to cover the entire material to be sandblasted. When the sand particles sprayed by the nozzle assembly 6 process the surface of the material, the sand particles and debris falling off the surface of the material will be splashed around together. At this time, the "air wall" formed by the sand-blocking gas can blow the sand particles and debris to the bottom to avoid the splashing range being too large and difficult to clean.

[0058] In this embodiment, the sand-blocking gas is preferably set to air or inert gas (flame retardant), which can not only block the sand particles, but also accelerate the cooling of the sand particles when the gas flows, thereby preventing the high-temperature sand particles due to sandblasting from splashing into the external environment, causing high temperature accumulation and causing safety accidents.

[0059] Furthermore, a second sand blocking layer 5 is provided on the air storage box 201 . The second sand blocking layer 5 includes a second motor 501 , a roller 502 , a blocking cloth 503 , and a weight block 504 .

[0060] Second motors 501 are mounted on the four sides of the rectangular air storage box 201. A roller 502 is connected to the drive shaft of each second motor 501. A blocking cloth 503 is wound around the roller 502 and positioned outside the air outlet 203. One end of the blocking cloth 503 is wound around the roller 502, and a weight block 504 is mounted on the other end of the blocking cloth 503.

[0061] The surface of the blocking cloth 503 is coated with a flame retardant coating, and the blocking cloth 503 itself is made of a high-strength fiber cloth with a certain degree of flexibility.

[0062] The horizontal width of the blocking cloth 503 is consistent with the horizontal length of the material box, and the vertical length of the blocking cloth 503 is consistent with the height distance from the device to the material to be sandblasted below.

[0063] Under normal circumstances, the roller 502 completely rolls up the blocking cloth 503, so that the entire sandblasting room can be folded to the top, without occupying the space below, thereby increasing the space of the factory building.

[0064] When sandblasting is in progress, the second motor 501 works synchronously, driving one end of the cloth 503 to separate from the roller 502. This end of the cloth 503 is kept moving vertically downward by the weight of the weight block 504, so that the cloths 503 on the four sides of the air storage box 201 form the "walls" of the sandblasting room, forming the sandblasting room structure.

[0065] Among them, when the cloth 503 is folded to the top of the device, the space for sandblasting the material is vacated, thereby increasing the working space of the entire production plant; and when the cloth 503 is moved down to the ground, a sandblasting room structure is formed by the device, and the material covered therein is sandblasted, which is fast and convenient, and there is no need for additional processing of the factory floor to adapt to the sandblasting work.

[0066] In addition, the baffle 503 can further block the splashing sand and debris through its own flame retardant surface and high-strength fiber cloth structure, preventing them from splashing out of the sandblasting room.

[0067] Thus far, various embodiments of the present invention have been described in detail. To avoid obscuring the concept of the present invention, some details known in the art have been omitted. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions of the present invention.
