Description

Technical Field

[0001] The utility model relates to the field of metal smelting, in particular to a cooling device for the production of metal smelting rolled products. Background Art

[0002] The existing patent (publication number: CN112916627A) proposes a cooling device for the production of metal smelting rolled products, including a placement plate. A plurality of guide rollers are movably sleeved inside the placement plate. A water receiving tank fixedly connected to the bottom of the placement plate is arranged below the guide rollers. Moving mechanisms are arranged on both sides of the bottom of the placement plate. A gear is fixedly connected to the moving mechanism on the left side. A fixed plate is fixedly connected to the top of the placement plate. A fixed shaft is rotatably connected to the left side of the fixed plate. However, during the process of "the fixed pipe drives the water sprinkling pipe to rotate, and the rotation of the water sprinkling pipe facilitates watering the metal, which is beneficial for water cooling the metal during transportation", a large amount of steam may be generated during the watering process. The high-temperature steam will burn the operators and affect the operation safety during the cooling process. Summary of the Invention

[0003] Aiming at the above deficiencies of the existing technology, the utility model provides a metal smelting rolled product production cooling device. When cooling the metal smelting rolled product during the production process, the rolling product positioning rollers connected to the upper covering table and the bottom bearing table are respectively pressed against the upper and lower sides of the metal rolled product. At the same time, the side sealing plates cover both sides of the upper covering table and the bottom bearing table. The upper covering table, the bottom bearing table and the side sealing plates form a relatively closed cooling cavity. After the cooling liquid is injected into the cooling cavity through the cooling liquid supply pipe and the cooling liquid injection table to cool the metal rolled product, it will fall into the waste liquid recovery tank through the lower drainage tank. The steam generated during the cooling process will enter the side steam discharge pipe. The steam is gradually cooled inside the side steam discharge pipe and finally also falls into the waste liquid recovery tank, thus avoiding the release of a large amount of steam to pollute the production environment and ensuring the safety during the cooling process.

[0004] The purpose of the utility model is realized through the following technical solutions:

[0005] A metal smelting rolled product production cooling device includes a bottom bearing table, a lifting hydraulic cylinder, side sealing plates, lower sealing gaskets, metal rolled products, rolling product positioning rollers, steam blocking blocks, an upper covering table, and a cooling liquid supply pipe. The bottom of the bottom bearing table has bottom support columns. The bottom of the bottom support columns has a waste liquid recovery tank. Both sides of the bottom bearing table have lower sealing ears. Both sides of the waste liquid recovery tank have side support columns. The top of the side support columns has a hydraulic cylinder support platform. The lifting hydraulic cylinder is fixedly connected to the top of the hydraulic cylinder support platform. The hydraulic rod of the lifting hydraulic cylinder passes through the hydraulic cylinder support platform and is fixedly connected to the upper covering table. The top of the upper covering table has a main steam discharge pipe and a cooling liquid injection table. The main steam discharge pipe and the cooling liquid injection table are arranged in an alternating manner. The cooling liquid injection table has a liquid supply groove inside.

[0006] On the side of the coolant injection table, a coolant supply pipe is fixedly connected. On the side of the main steam discharge pipe, there is a side steam discharge pipe. Inside the main steam discharge pipe, there is a plug connection groove, which is adapted to the steam plug. The plug connection groove is connected to the steam plug, and the steam plug slides inside the plug connection groove. The top of the steam plug and the top of the plug connection groove are connected by a spring. Inside the bottom bearing table, there is a lower drain tank.

[0007] On the top of the bottom bearing table and the bottom of the upper covering table, there are positioning roller connection grooves. Inside the positioning roller connection grooves, there are positioning roller connection posts, which are rotatably connected to the calendered product positioning rollers. The calendered product positioning rollers on the upper and lower sides respectively press on the upper and lower sides of the metal calendered product. On both sides of the upper covering table, there are upper sealing ears, and at the bottom of the upper sealing ears, there are sealing plate positioning posts.

[0008] On the top of the side sealing plate, there is a sealing plate positioning groove, which is adapted to the sealing plate positioning post. The sealing plate positioning groove is connected to the sealing plate positioning post, and the sealing plate positioning groove slides outside the sealing plate positioning post. The bottom of the sealing plate positioning post and the bottom of the sealing plate positioning groove are connected by a spring. Beneficial effects

[0009] 1. When the present utility model cools the metal smelting and calendered product during the production process, the calendered product positioning rollers connected to the upper covering table and the bottom bearing table respectively press on the upper and lower sides of the metal calendered product. At the same time, the side sealing plate covers both sides of the upper covering table and the bottom bearing table. The upper covering table, the bottom bearing table, and the side sealing plate form a relatively closed cooling cavity. After the coolant is injected into the cooling cavity through the coolant supply pipe and the coolant injection table to cool the metal calendered product, it will fall into the waste liquid recovery tank through the lower drain tank. The steam generated during the cooling process will enter the side steam discharge pipe, and the steam will gradually cool inside the side steam discharge pipe and finally also fall into the waste liquid recovery tank, thereby avoiding a large amount of steam release from polluting the production environment and ensuring the safety during the cooling process.

[0010] 2. The bottom of the sealing plate positioning post of the present utility model is connected to the bottom of the sealing plate positioning groove by a spring, so that the side sealing plate can slide a certain distance on the side of the upper covering table, enabling the side sealing plate and the connected lower sealing gasket to continuously press on the upper part of the lower sealing ear after the distance between the adjacent upper and lower calendered product positioning rollers is changed. When the calendered product positioning rollers press on metal calendered products with different thicknesses, the sealing of the cooling cavity can be maintained, enabling this device to carry out the production and cooling operations of calendered products with different thicknesses and ensuring the adaptability of this device.

[0011] 3. The top of the steam plugging block of the present utility model is connected to the top of the plugging block connection groove through a spring. At the same time, the steam plugging block is located below the interface of the side steam discharge pipe and the main steam discharge pipe, so that the coolant will not easily flow out through the side steam discharge pipe after being injected into the cooling cavity. Only when enough steam is generated and the steam pressure inside the cooling cavity is high enough, the steam plugging block will be lifted, and the steam will be discharged through the side steam discharge pipe, avoiding waste caused by the outflow of the coolant during the cooling process and reducing the cost of the cooling operation.

[0012] 4. The positioning roller connection grooves on the same side of the present utility model are designed in multiple groups in parallel. At the same time, baffles are arranged between adjacent positioning roller connection grooves, so that the coolant and the generated steam entering the cooling cavity will not easily leak from the connection between the calender roll for positioning the rolled product and the metal rolled product, improving the sealing performance inside the cooling cavity.
