[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0023] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are all based on the attached Figure 1 drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0024] As Figures 1-4As shown in the figure, a new type of heat-insulating and heat-generating riser includes a riser body 1. The top of the riser body 1 is open, and a cover body 2 is movably arranged at the open part. An air vent 5 penetrating its surface is opened on the cover body 2. An outlet 8 penetrating the bottom of the riser body 1 is opened on the riser body 1. A rotating rod 4 is rotatably connected to the middle of the cover body 2. A first cover plate 7 capable of covering the air vent 5 is fixedly connected to the outer wall near the middle of the rotating rod 4 through a connecting strip 6. The bottom of the rotating rod 4 is fixedly connected to a second cover plate 13 capable of covering the outlet 8 through a connecting block 12.

[0025] Specifically, the open part of the riser body 1 can be covered by the cover body 2. At the same time, the cover body 2 can be disassembled for continued use after replacing the riser body 1, reducing costs. The air vent 5 can intake air during the replenishment of metal to maintain the air pressure inside the riser body 1. The cover body 2 supports the rotation of the rotating rod 4, drives the connecting strip 6 and the connecting block 12 to rotate through the rotating rod 4, so that the first cover plate 7 and the second cover plate 13 follow the rotation, and then the first cover plate 7 and the second cover plate 13 cover or open the air vent 5 or the outlet 8.

[0026] Furthermore, a positioning column 9 is fixedly connected to the bottom inside the riser body 1. A positioning sleeve 11 is fixedly arranged at the bottom of the rotating rod 4, and an insertion hole for inserting the positioning column 9 is opened on the positioning sleeve 11.

[0027] Specifically, when installing the rotating rod 4, the positioning column 9 is inserted into the insertion hole on the positioning sleeve 11 for positioning, and at the same time, it further supports the stable rotation of the rotating rod 4.

[0028] Furthermore, a part of the cover body 2 is configured as a detachable lifting cover body 15, and the lifting cover body 15 is hinged to the cover body 2. A handle 16 is arranged on the lifting cover body 15.

[0029] Specifically, the cover body 2 and the lifting cover body 15 covering the open part of the riser body 1 can increase the sealing performance of the riser body 1, and lifting the lifting cover body 15 is convenient for adding liquid metal.

[0030] Furthermore, the riser body 1 is in a conical shape with a gradually increasing diameter from the bottom to the top to increase the liquid metal storage capacity.

[0031] Furthermore, a detachable annular handle sleeve 14 is sleeved on the outer wall of the riser body 1. The annular handle sleeve 14 is movably sleeved on the outer wall of the riser body 1, which is convenient for taking the riser body 1 and avoiding high temperature. At the same time, it can be installed on a good riser body 1 after the riser body 1 is damaged and cannot be used.

[0032] Furthermore, a cover groove 3 capable of accommodating the cover body 2 is arranged along the inner edge at the open part of the riser body 1. While increasing the sealing performance, it can ensure the stable placement of 2.

[0033] Furthermore, the rotating rod 4 is arranged vertically, and a handle 10 is fixedly connected to the top to facilitate driving the rotation of the rotating rod 4.

[0034] Furthermore, the positioning post 9 is cylindrical so that the positioning sleeve 11 can rotate on the positioning post 9.

[0035] In the above structure, the riser body 1 is installed above the casting, then the cover body 2 is placed inside the cover groove 3, and at the same time, 119 is inserted on the positioning sleeve 11. At this time, the first cover plate 7 covers the vent hole 5 and the second cover plate 13 covers the liquid outlet 8. The lifting handle 16 is used to lift the lifting cover body 15, and the liquid metal is poured into the riser body 1. Then the lifting cover body 15 is covered to achieve heat preservation. When metal needs to be replenished, the handle 10 is used to drive the rotating rod 4 to rotate. The rotating rod 4 synchronously drives the first cover plate 7 and the second cover plate 13 to rotate, so that the vent hole 5 and the liquid outlet 8 are unblocked. Then the liquid metal flows to the casting for replenishment. After the replenishment is completed, 18 is used to drive the rotating rod 4 to rotate, so that the first cover plate 7 and the second cover plate 13 cover the vent hole 5 and the liquid outlet 8. Therefore, it has good heat preservation performance and can prevent the liquid metal from splashing.

[0036] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present application.
