Description

Technical Field

[0001] The utility model belongs to the technical field of risers, and particularly relates to a heat-insulating and heat-generating straight-through open riser. Background Technique

[0002] The exothermic riser is made by adding a certain amount of thermite, flux, oxidant and the above-mentioned heat-insulating and heat-preserving materials when making the riser. It has both heat-generating and heat-insulating functions. During casting, the riser is quickly ignited and burned at about 680°C. The heat released at this time raises the temperature of the molten iron in the riser, makes the solidification time of the molten metal in the riser longer, extends the feeding time, and improves the feeding efficiency of the riser to the casting.

[0003] When the exothermic riser is in use, its inner wall contacts the molten metal. After a long time, it needs to be maintained, while the outer wall does not. However, the existing exothermic risers are mostly of an integral structure. When replacing, only the whole riser structure can be replaced, which not only has a high maintenance cost but also wastes materials. Therefore, it is necessary to design a new riser to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat-insulating and heat-generating straight-through open riser to solve the problem that the integral riser can only be replaced as a whole during replacement, resulting in high maintenance costs and material waste as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat-insulating and heat-generating straight-through open riser, including an outer cylinder, an inner cylinder is arranged inside the outer cylinder, a locking component is arranged between the outer cylinder and the inner cylinder, the locking component includes a clamping block, a clamping groove, a side cover, a spring, a plug rod and a jack, the clamping blocks are symmetrically fixed on both sides of the inner cylinder and are slidably inserted into the clamping grooves opened on the inner wall of the outer cylinder, the top of the clamping groove is open and the bottom is closed, the side covers are elastically connected to both sides of the outer cylinder through springs, the plug rods are fixed on the inner surface of the side covers and are inserted into the jacks opened on the surface of the clamping blocks.

[0006] Preferably, the clamping block is of a rectangular structure and matches the inner wall of the clamping groove.

[0007] Preferably, one end of the spring is fixedly connected to the inner surface of the side cover, and the other end is fixedly connected to the outer surface of the outer cylinder.

[0008] Preferably, the locking component further includes a pull ring, and the pull ring is rotatably connected to the outer surface of the side cover.

[0009] Preferably, the inner cylinder further includes a cylinder body and a top ring, the top ring is fixed at the top of the cylinder body and overlaps the top of the outer cylinder.

[0010] Preferably, a handle is fixed to the outer edge of the top ring. The number of handles is two, and they are symmetrically distributed on both sides of the top ring.

[0011] Preferably, a cover assembly is provided at the top of the inner cylinder. The cover assembly includes a top cover, a docking ring, a threaded post, a through hole, and a threaded knob. The top cover is lapped on the surface of the top ring. The docking ring is fixed to the bottom surface of the top cover and inserted into the interior of the cylinder body. The threaded posts are symmetrically fixed on the upper surface of the top ring and penetrate through the through holes opened on the surface of the top cover. The threaded knob is threadedly connected to the top end of the threaded post.

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

[0013] By designing the riser as a split structure composed of an outer cylinder and an inner cylinder, personnel can perform regular maintenance and replacement on the inner cylinder, while the external outer cylinder can continue to be used, reducing the maintenance cost and saving materials. Through the designed locking component, the fixed connection between the outer cylinder and the inner cylinder can be realized, ensuring the stable connection between the two, and the disassembly of the inner cylinder is also convenient and fast.

The top of the clamping groove 302 is open and the bottom is closed. When disassembling and assembling, the inner barrel 200 can be lifted upwards to move the clamping block 301 out of the opening at the top of the clamping groove 302, so that the inner barrel 200 can be disassembled. The side covers 303 are elastically connected to both sides of the outer barrel 100 through springs 304. The plug rods 305 are fixed on the inner surface of the side covers 303 and are inserted into the jacks 306 opened on the surface of the clamping blocks 301 to fix the inner barrel 200 inside the outer barrel 100.
