Description

Technical Field

[0001] The utility model belongs to the technical field of experimental equipment, and in particular relates to a rapidly replaceable spray deposition conduit. Background Art

[0002] Since the spray material is in a solid-liquid mixed state during the spray deposition plating process, the spray deposition plating equipment should remain relatively sealed to ensure that the spray material liquid does not leak. Therefore, in the design of the spray deposition plating equipment, there is only one workpiece discharge outlet, namely the discharge valve. Since the discharge valve can only allow the steel plated parts to be discharged, the waste spray material, spray deposition medium and cleaning waste liquid can only be discharged from the spray material delivery chamber outlet by removing the connection between the conduit and the spray material delivery chamber outlet. The connection between the spray material delivery chamber outlet and the conduit is relatively traditional, which is troublesome to disassemble, and the connection between the two is prone to unstable leakage after multiple disassembly. In addition, when the spray deposition plating equipment needs to replace the spray material and the spray deposition medium in the preparation of different spray deposition coatings and clean the spray material delivery chamber and the spray deposition chamber inside the spray deposition equipment, it is also necessary to quickly disassemble the connection between the conduit and the spray material delivery chamber outlet so that the waste spray material and cleaning waste liquid are discharged from the outlet. Therefore, the utility model aims to connect a quickly replaceable conduit to the spray material delivery chamber outlet of the spray deposition plating equipment to facilitate the replacement of the spray deposition medium and the cleaning of the interior of the device.

[0018] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0019] Example 1

[0020] like Figure 1 As shown, a quickly replaceable spray deposition catheter comprises a fixture 1 , a movable sleeve 3 , a fixed sleeve 4 , a movable catheter 5 , a fixed catheter 6 and a protrusion 9 .

[0021] The lower end of the fixed conduit 6 is fixedly connected to the upper end of the fixed sleeve 4. The movable conduit 5 passes through the movable sleeve 3 and the fixed sleeve 4, and its upper end is tightly connected to the lower end of the fixed conduit 6. The inner diameters of the movable conduit 5 and the fixed conduit 6 are the same, and after connection, the movable conduit 5 and the fixed conduit 6 are connected. The outer surface of the movable conduit 5 is loosely matched with the inner wall of the movable sleeve 3 and is threadedly connected to the inner wall of the fixed sleeve 4. The upper end of the movable sleeve 3 is connected to the lower end of the fixed sleeve 4, and the clamp 2 is removably fixed to the connection between the movable sleeve 3 and the fixed sleeve 4, tightly connecting the movable sleeve 3 and the fixed sleeve 4. A protrusion 9 is provided on the outer wall of the movable conduit 5, and a hole is provided in the protrusion.

[0022] In this embodiment, an external thread 7 is provided on the outer surface of the movable catheter 5, and an internal thread 8 is provided on the inner surface of the fixed sleeve 4; the external thread 7 and the internal thread 8 match, so that the movable catheter 5 and the fixed sleeve 4 are threadedly connected, and the length of the external thread 7 provided on the outer surface of the movable catheter 5 is the same as the length of the fixed sleeve 4.

[0023] The protruding piece 9 is arranged on the outer wall of the lower part of the movable conduit 5 to avoid affecting the movable conduit 5 passing through the movable sleeve 3 and the fixed sleeve 4, and its upper end is tightly connected with the lower end of the fixed conduit 6.

[0024] In this embodiment, the movable sleeve 3 and the fixed sleeve 4 have the same size; the clamp 1 is fixed to the connection between the movable sleeve 3 and the fixed sleeve 4. A circular protrusion protruding outward from the sidewall of the sleeve is provided at one end of the movable sleeve 3 and the fixed sleeve 4. After the circular protrusions of the movable sleeve 3 and the fixed sleeve 4 are tightly connected, they are loosely fitted into the groove of the clamp 1. The clamp 1 comprises two semicircular bodies, each with a groove on its inner wall. Corresponding tightening heads are provided at both ends of the semicircular bodies, each with a hole. Bolts pass through the holes in the tightening heads, securing the two semicircular bodies into a circular body. An annular groove is formed on the inner wall of the circular body, and the connection between the movable sleeve 3 and the fixed sleeve 4 is fixed within the annular groove of the circular body.

[0025] In this embodiment, the movable sleeve 3, the fixed sleeve 4 and the fixed conduit 6 are all made of steel pipes, the outer walls of which are hot-dip galvanized and the inner walls of which are anti-corrosion plastic-coated, while the movable conduit 5 is made of PVC external threaded pipe.

[0026] The operating principle of the quickly replaceable spray deposition conduit described in this embodiment is as follows: the upper end of the fixed conduit 6 is connected to the discharge outlet of the spray material conveying chamber of the spray deposition plating device, the movable conduit 5 is passed through the movable sleeve 3, and then a wrench is inserted into the sleeve hole 9 to thread the external thread 7 provided on the upper part of the movable conduit 5 with the internal thread 8 inside the fixed sleeve 4. The upper end of the movable conduit 5 is tightly connected to the lower end of the fixed conduit 6, and the movable conduit 5 and the fixed conduit 6 are connected to form a channel. The lower end of the movable conduit 5 is connected to the spray material chamber of the spray deposition plating device. The upper end of the movable sleeve 3 is connected to the lower end of the fixed sleeve 4, and the clamp 2 is detachably fixed to the connection between the movable sleeve 3 and the fixed sleeve 4 by bolts 2, and the movable sleeve 3 and the fixed sleeve 4 are tightly fixed. The spray material enters the spray material conveying chamber of the spray deposition plating device, enters the fixed conduit 6 through the discharge outlet of the spray material conveying chamber, and then enters the spray material chamber of the spray deposition plating device through the movable conduit 5, and then the spray deposition plating is carried out.

[0027] The spray deposition medium in the spray deposition plating equipment will wear and consume after working for a period of time under high-intensity collision and impact conditions. At this time, the conduit I can be disassembled and the spray deposition plating equipment can be operated to allow the old spray medium to be discharged through the fixed conduit 6 and the fixed sleeve 4 in turn; at the same time, when preparing different spray deposition coatings, the conduit I can be quickly disassembled to clean the spray material conveying chamber and the spray deposition chamber inside the spray deposition equipment. The rear conduit I is disassembled first, and then the cleaned waste liquid is discharged through the fixed conduit 6 and the fixed sleeve 4 in turn. After the cleaning is completed, the conduit I is reassembled to replace the new spray material.

[0028] When replacing or removing the catheter, first use a wrench socket to remove the bolt 2 on the fixture 1, remove the fixture 1, and then use a wrench to rotate the sleeve hole 9 to unscrew the movable catheter 5 of catheter I from the fixed sleeve 4 of catheter II.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
