Technical Field

[0001] This utility model belongs to the field of cantilever section cylinder spraying technology, specifically relating to a spraying device with residual material recovery. Background Technology

[0002] The tunneling machine cantilever section is a general term for the cantilever structure and its external cylindrical protective or support components in a cantilever tunneling machine. Its core function is to support the cutting head, transmit power, and adapt to efficient tunneling under complex geological conditions. The tunneling machine cantilever section is usually made of high-strength steel plates welded into a cylindrical shape. After the tunneling machine cantilever section is processed, a coating is usually formed on its surface using a spraying device.

[0003] The cantilever section of a tunneling machine can be coated with powder. The powder coating is applied to the surface of the object by electrostatic or fluidized bed method, and then cured by heating. There is no solvent emission, which is environmentally friendly.

[0004] In practical applications, some of the sprayed powder from the cantilever section of the tunneling machine will escape from both sides of the cantilever section during spraying operations, resulting in a waste of powder material. Utility Model Content

[0005] The purpose of this invention is to provide a spraying device with residual material recovery, which aims to solve the problem in the prior art where some of the sprayed powder escapes from both sides of the tunneling machine's cantilever section cylinder during spraying operations, thus causing waste of powder material.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spraying device with residual material recovery, comprising a base, a support arm, a movable frame, and a spraying assembly. The upper surface of the base is connected to the support arm, which is placed on a support device. The bottom side of the support arm is provided with a movable frame. The side surface of the movable frame is equipped with a spraying assembly for powder spraying. The surface of the support arm is connected to a drive rotation assembly for driving the movable frame to rotate. The side surface of the movable frame is connected to a residual material recovery assembly for collecting residual spraying powder.

[0007] As a preferred embodiment of the spraying device with residual material recovery according to this utility model, the spraying assembly includes an electrostatic spraying powder supply tank, a powder supply pipe, a ball valve, a spray pipe, and a nozzle. The electrostatic spraying powder supply tank is installed on the outer surface of the movable frame. The powder supply pipe is connected through the side surface of the electrostatic spraying powder supply tank. A ball valve is installed in the middle of the powder supply pipe. The end of the powder supply pipe is connected through the spray pipe installed on the side surface of the movable frame. A nozzle is connected to the side surface of the spray pipe and is installed on the side surface of the movable frame and extends to the other side.

[0008] As a preferred embodiment of the spraying device with residual material recovery of this utility model, the drive rotation assembly includes a bearing, a rotating shaft, a driven bevel gear, a drive motor and a driving bevel gear, and a bearing is fitted and installed on the top of the support arm. The rotating shaft connected to the movable frame is connected through the inside of the bearing.

[0009] As a preferred embodiment of the spraying device with residual material recovery of this utility model, a driven bevel gear is connected to the top of the rotating shaft, a drive motor is installed on the upper surface of the support arm, and the output end of the drive motor is connected to a driving bevel gear that meshes with the driven bevel gear.

[0010] As a preferred embodiment of the spraying device with waste material recovery according to this utility model, the waste material recovery component includes a Roots vacuum pump, a connecting pipe, a cyclone separator, a collection bin, a negative pressure pipe, a suction hopper, and a connecting bracket. The Roots vacuum pump is installed on the side surface of the movable frame, and the input end of the Roots vacuum pump is connected to the connecting pipe. The end of the connecting pipe is connected to the cyclone separator installed on the side surface of the movable frame, and the bottom of the cyclone separator is connected to the collection bin.

[0011] As a preferred embodiment of the spraying device with residual material recovery of this utility model, the negative pressure pipe is connected through to the side surface of the cyclone separator. The negative pressure pipe adopts a pair of two-pipe joints, and the ends of the two pipe joints of the negative pressure pipe are respectively connected through to a suction hopper. The two suction hoppers are respectively connected to the movable frame through a connecting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when the Roots vacuum pump is running, a negative pressure is generated inside the cyclone separator through the connecting pipe. When the cyclone separator generates a negative pressure, a suction force is generated inside the suction hopper from the negative pressure pipe. In this way, the powder that is not attached to the surface of the cantilever section cylinder can be sucked into the inside of the negative pressure pipe through the suction hopper. Then, the powder inside the negative pressure pipe can enter the inside of the cyclone separator, which can separate the powder from the air. The separated powder can fall into the inside of the collection bin, thereby realizing the recovery of residual powder.

[0014] In this invention, the drive motor rotates the active bevel gear during operation. When the active bevel gear rotates, it drives the rotating shaft to rotate through the driven bevel gear, which in turn drives the movable frame to rotate. When the movable frame rotates, it can drive the spraying assembly to perform a circumferential spraying on the cantilever section of the cylindrical tunneling machine. This can achieve full coverage spraying of the cantilever section, thereby improving the spraying efficiency of the cantilever section. Attached Figure Description

The nozzle 405, which is installed on the side surface of the movable frame 3 and extends to the other side, is connected to the side surface of the spray pipe 404.

[0027] In practical use, after opening the ball valve 403, the powder inside the electrostatic powder supply tank 401 can enter the inside of the spray pipe 404 through the powder supply pipe 402, and then the powder inside the spray pipe 404 can be sprayed at high speed onto the surface of the tunneling machine cantilever section cylinder through the nozzle 405.

[0028] Preferably, the drive rotation assembly 5 includes a bearing 501, a rotating shaft 502, a driven bevel gear 503, a drive motor 504, and a driving bevel gear 505. The bearing 501 is fitted and installed on the top of the support arm 2, and the rotating shaft 502, which is connected to the movable frame 3, is connected through the interior of the bearing 501.

[0029] In practical use, when the rotating shaft 502 is subjected to a force, it can rotate and drive the movable frame 3 to rotate. When the movable frame 3 rotates, it can drive the spraying assembly 4 to perform a circumferential spraying on the cylindrical tunneling machine cantilever section.

[0030] Preferably, a driven bevel gear 503 is connected to the top of the rotating shaft 502, a drive motor 504 is mounted on the upper surface of the support arm 2, and the output end of the drive motor 504 is connected to a driving bevel gear 505 that meshes with the driven bevel gear 503.

[0031] In practical use, when the drive motor 504 is running, it can drive the active bevel gear 505 to rotate. When the active bevel gear 505 rotates, it can drive the driven bevel gear 503 to rotate through the meshing structure. When the driven bevel gear 503 rotates, it can drive the rotating shaft 502 to rotate inside the bearing 501, thus realizing the transmission of the rotating shaft 502.

[0036] Working principle: When using this spraying device, first move the tunneling machine cantilever section cylinder between the spraying component 4 and the residual material recovery component 6. Then, the ball valve 403 can be opened. After the ball valve 403 is opened, the powder inside the electrostatic spraying powder supply tank 401 can enter the interior of the spray pipe 404 through the powder supply pipe 402. Then, the powder inside the spray pipe 404 can be sprayed out through the nozzle 405, so that the powder can adhere to the surface of the cantilever section cylinder.

[0037] Simultaneously, the Roots vacuum pump 601 can be operated. When the Roots vacuum pump 601 is running, it can generate negative pressure inside the cyclone separator 603 through the connecting pipe 602. When the cyclone separator 603 generates negative pressure, it can generate suction from the negative pressure pipe 605 inside the suction hopper 606. In this way, the powder that is not attached to the surface of the cantilever section cylinder can be sucked into the inside of the negative pressure pipe 605 through the suction hopper 606. Then, the powder inside the negative pressure pipe 605 can enter the inside of the cyclone separator 603. The cyclone separator 603 can separate the powder from the air. The separated powder can fall into the inside of the collection bin 604, thereby realizing the recovery of residual powder.

When the active bevel gear 505 rotates, it can drive the driven bevel gear 503 to rotate. When the driven bevel gear 503 rotates, it can drive the rotating shaft 502 to rotate and drive the movable frame 3 to rotate. When the movable frame 3 rotates, it can drive the spraying assembly 4 to perform a circumferential spraying on the cylindrical tunneling machine cantilever section.
