Description

Technical Field

[0001] The utility model belongs to the technical field related to brake disc processing, in particular to a multi-layer automatic surface drying device for a cold core brake disc. Background Art

[0002] Cold core brake disc usually refers to the brake disc manufactured by special process. This kind of brake disc actively sends air into the brake disc body by changing the brake disc ventilation mechanism, and exhausts air outward in combination with the brake disc fan blades to increase the air intake and exhaust volume. During operation, the brake disc is cooled. During the production and manufacturing process, when the brake disc is processed, it needs to be cleaned. After cleaning, in order to prevent the brake disc from rusting, it needs to be dried on the surface to quickly dry the surface of the brake disc. However, it still has the following disadvantages in actual use:

[0003] During the surface drying process, the cold core brake disc surface drying device directly heats the surface of the brake disc through the drying equipment, so that the brake disc is surface dried. During operation, the temperature in the drying equipment is high and the oxygen content is high, which will cause the surface of the brake disc to be rapidly oxidized, affecting the stability of the brake disc surface drying;

[0004] When the cold core brake disc surface drying device is working, it usually passes through the drying equipment directly through the tray. When the drying equipment is running, when the surface is dried directly through a single layer of tray, the working efficiency is low. Utility Model Content

[0005] The utility model aims to provide a multi-layer automatic surface drying device for a cold core brake disc. By arranging a heat-insulating shell, a jet chamber, a tray assembly, a burner and an exhaust fan, the utility model solves the problems that the internal temperature of the cold core brake disc surface drying device is high, sufficient oxygen can easily cause oxidation of the brake disc surface, and the surface drying efficiency through a single-layer tray is low.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a multi-layer automatic surface drying device for a cold core brake disc, comprising a heat-insulating shell, a jet chamber, a tray assembly, a burner and an exhaust fan. A fixing port is provided on the top of the heat-insulating shell, a jet chamber is fixed in the fixing port, an exhaust fan is fixed at the top center of the jet chamber, an exhaust pipe is fixedly connected to the input end of the exhaust fan, the exhaust pipe is vertically passed through and fixed in the jet chamber, burners are arranged above the spray chambers on both sides of the exhaust fan, electric rollers are equidistantly arranged on the lower part of the inner wall of the heat-insulating shell, two output shafts of the electric rollers are fixed in the heat-insulating shell, a tray assembly is arranged above the electric roller, and when working, the heat-insulating shell is used to insulate the heat-insulating shell, hot flue gas generated in the burner is transported to the heat-insulating shell through the jet chamber, the brake disc on the tray assembly is dried, the dried hot flue gas is generated by the burner and transported to the jet chamber, and the air in the heat-insulating shell is extracted by the exhaust fan.

[0008] Furthermore, the top of the insulation shell is fixedly connected to an air inlet pipe, which is arranged at the top of the insulation shell outside the jet chamber. When the insulation shell is working, air is transported into the insulation shell through the air inlet pipe to cool the tray in the insulation shell.

[0009] Furthermore, fixing holes are provided in the center of the top and bottom of the jet chamber, connecting holes are provided on both sides of the fixing hole at the top of the jet chamber, the exhaust pipe is fixed in the two fixing holes, and jet holes are evenly provided on both sides of the fixing hole at the bottom of the jet chamber. When the jet chamber is working, the exhaust pipe is fixed through the fixing holes.

[0010] Furthermore, the top of the burner is fixedly connected to two air inlet pipes, the output end of the burner is fixedly connected to an exhaust pipe, the bottom end of the exhaust pipe is connected to the connecting hole, the burner transports air and fuel gas into the burner through the air inlet pipe, and transports the hot flue gas after combustion into the jet chamber through the exhaust pipe.

[0011] Furthermore, the tray assembly includes a fixed frame, a support tray and a support block. The support tray is fixed to the upper part of the inner wall of the fixed frame, and support blocks are fixed at the four corners of the top of the fixed frame. When the tray assembly is working, the support tray is fixed in it through the fixed frame, and the brake disc is supported thereon by the support tray.

[0012] Furthermore, the tray assembly also includes a pin, and a pin is fixed at the top center of each support block, and the pin is inserted into the fixed frame located above. When the tray assembly is working, the pin is inserted into the fixed frame located above, so that the two tray assemblies are combined together.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the internal temperature of the cold core brake disc surface drying device is high and sufficient oxygen can easily cause oxidation of the brake disc surface by arranging a heat-insulating shell, a jet chamber, a burner and an exhaust fan. Air and gas are transported to the burner through two air inlet pipes, and after being burned by the burner, they are transported to the jet chamber through the exhaust pipe, and then sprayed into the heat-insulating shell through the jet hole at the bottom of the jet chamber, so that the surface of the brake disc on the tray assembly passing under the jet hole is quickly heated and dried. The exhaust fan is then started to generate negative pressure in the exhaust pipe, and the smoke for drying the brake disc in the heat-insulating shell is sucked in and discharged through the exhaust fan. During the drying process, the smoke enters the heat-insulating shell, reduces the oxygen content of the heat-insulating shell, and dries the brake disc surface at the same time, so that when the cold core brake disc surface drying device works on the brake disc surface drying, the oxygen content is lower, and oxidation of the brake disc surface is reduced.

[0015] The utility model solves the problem of low surface drying efficiency of a cold core brake disc surface drying device through a single-layer tray by setting a heat-insulating shell and a tray assembly. A tray assembly is placed on a conveying structure outside the heat-insulating shell, and then the brake disc is placed on a supporting tray in a fixed frame and supported by the supporting tray. Then another tray assembly is arranged above the arranged tray assembly, so that a plug post is inserted into a fixed frame on the upper tray assembly, so that two upper and lower corresponding tray assemblies are combined, and then the brake disc is placed on the supporting tray. The above work is repeated until a suitable position is set between the tray assemblies, and then the electric roller is started and transported to the electric roller in the heat-insulating shell by the external conveying structure for surface drying. During operation, the cold core brake disc surface drying device can perform surface drying through multiple layers of trays, and the working efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS
