Description

Technical Field

[0001] The utility model relates to the technical field of graphite tube processing, in particular to a graphite tube surface spraying device. Background Art

[0002] Graphite piping refers to the combination of impermeable graphite tubes and fittings. Graphite tubes are divided into pressure tubes and impregnated tubes. Graphite piping is used to transport corrosive media without metal ion pollution. It also has good thermal conductivity and can be used for air cooling or water cooling.

[0003] Impregnated graphite tubes are divided into two categories. One is a thermosetting resin graphite profiled tube that is impregnated with resin after being baked at high temperature (700°C), or a raw material extruded tube with asphalt as a binder that is baked and graphitized and then impregnated with resin. The former is called a carbonized tube, and the latter is a graphitized tube. This type of graphitized tube is also used as a heat exchange tube; the other is a graphite rod that is processed into a tube and then impregnated with resin, or a cast tube that is baked and impregnated with resin. When impregnating a thermosetting resin graphite profiled tube with resin, the resin can be evenly sprayed on the surface of the thermosetting resin graphite profiled tube with the help of a surface spraying device.

[0004] When using a surface spraying device to spray resin on the surface of a thermosetting resin graphite corrugated tube, due to the difference in diameter of the thermosetting resin graphite corrugated tube being sprayed, when the spraying speed of the spraying device remains unchanged, the amount of resin sprayed on the periphery of the thermosetting resin graphite corrugated tube per unit time decreases, and the thickness of the sprayed resin is thinner. If the amount of resin sprayed per unit time is increased, it is necessary to change the resin supply per unit time, and perform a series of adjustments on the production line, which is rather cumbersome. For this reason, we propose a graphite tube surface spraying device. Utility Model Content

[0013] Furthermore, a rubber pad is bonded to the side wall of the graphite tube clamping bar.

[0014] Furthermore, two ends of the spray plate extend to the inner sides of the rotating frames on both sides respectively.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, a graphite tube surface spraying device includes a counterweight base plate 1, the surface of the counterweight base plate 1 is structured with a longitudinal slide groove, and a first limit block 4 and a first limit rod 2 penetrating the first limit block 4 are slidably arranged in the longitudinal slide groove, the outer periphery of the first limit rod 2 is sleeved with a first return spring 3 abutting against the first limit block 4, a symmetrically arranged graphite tube rotating component 5 is installed between the surface of the counterweight base plate 1 and the surface of the first limit block 4, a support rod 7 is installed on the side wall of the counterweight base plate 1, and a spraying plate 8 is installed on the top of the support rod 7, an intelligent control panel 9 is installed on the surface of the spraying plate 8, a plurality of columns 10 are inserted into the surface of the counterweight base plate 1, and a receiving plate 11 is fixed between the tops of the columns 10.

[0025] In order to drive the thermosetting resin graphite profiled tube to be sprayed to rotate at a uniform speed, so as to evenly spray the resin on the outer periphery of the thermosetting resin graphite profiled tube, and to quickly clamp and fix the thermosetting resin graphite profiled tubes of different diameters, and to control the rotation speed according to the diameter of the thermosetting resin graphite profiled tube to ensure the spraying thickness of the resin, the graphite tube rotating component 5 includes a vertical plate 51, a circular frame 52 is fixed on the top of the vertical plate 51, and a rotating frame 53 protruding from the circular frame 52 is rotatably arranged in the circular frame 52, the side wall of the rotating frame 53 is structured with a symmetrically arranged card groove 54, and a second limit block 57 and a second limit rod 55 penetrating the second limit block 57 are slidably arranged in the card groove 54, the outer periphery of the second limit rod 55 is sleeved with a second return spring 56 abutting against the side wall of the second limit block 57, and an arc-shaped graphite tube clamping strip 58 is fixed to the side wall of the second limit block 57. A circular groove is constructed on the inner side of the strip 58, and an infrared diameter measuring sensor 59 is installed in the circular groove. The infrared diameter measuring sensor 59 is connected to the intelligent control panel 9. A rotating motor 6 is installed on the outer wall of the circular frame 52 of the graphite tube rotating component 5 on one side, and the output shaft of the rotating motor 6 is transmission-connected to the side wall of the rotating frame 53. The rotating motor 6 is connected to the intelligent control panel 9 through a circuit board. The intelligent control panel 9 controls the rotation speed of the rotating motor 6 in time according to the diameter data detected by the infrared diameter measuring sensor 59, thereby controlling the rotation speed of the thermosetting resin graphite corrugated tube to ensure that the resin spraying thickness is sufficient. A rubber pad is bonded to the side wall of the graphite tube clamping strip 58. The rubber pad is used to play a buffering role between the thermosetting resin graphite corrugated tube and the graphite tube clamping strip 58 to avoid clamping the two ends of the thermosetting resin graphite corrugated tube spraying plate 8 respectively extending to the inner side of the rotating frame 53 on both sides.

[0026] It should be noted that the utility model is a graphite tube surface spraying device. When in use, first pull a group of slidable graphite tube rotating parts 5 outward, so that the vertical plate 51 moves outward with the first limit block 4, squeezing the first reset spring 3. At this time, the spacing of the rotating frame 53 increases, and the graphite tube clamping strips 58 are moved to both sides. After the thermosetting resin graphite profiled tube is placed between the graphite tube clamping strips 58, the graphite tube clamping strips 58 are released, and the graphite tube clamping strips 58 are driven to reset under the action of the second reset spring 56, thereby clamping and fixing the thermosetting resin graphite profiled tube, and keeping the thermosetting resin graphite profiled tube located on the axis between the rotating frames 53. At this time, the infrared diameter measuring sensor 59 detects the diameter of the thermosetting resin graphite profiled tube and feeds it back to the intelligent control panel 9. Since the resin spraying flow rate remains unchanged, the intelligent control panel 9 obtains the circumference value of the thermosetting resin graphite profiled tube according to the diameter, and calculates the rotation speed of the thermosetting resin graphite profiled tube according to the value, and then controls the rotation speed of the rotating motor 6 through the circuit board. The rotating motor 6 drives the rotating frame 53 on one side to rotate, thereby driving the thermosetting resin graphite profiled tube together with the rotating frame 53 to rotate around the extension line of the center of the circular frame 52, and the spraying plate 8 sprays a certain thickness of resin on the outer periphery of the thermosetting resin graphite profiled tube.
