Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology of slag cooler, and more specifically, to a waste heat recovery and efficiency-enhancing heat exchange device for slag cooler. Background Technology

[0002] Slag coolers are primarily used to remove slag from high-temperature environments. However, the slag itself is not effectively utilized and is typically discharged directly, wasting thermal energy and potentially causing environmental pollution. In recent years, with the popularization of energy conservation and emission reduction concepts and technological advancements, the retrofitting and optimization of existing equipment has become a significant trend. Retrofitted slag coolers can effectively reduce thermal energy waste and, to some extent, reduce pollution emissions and improve energy efficiency. Therefore, innovation in waste heat recovery technology and equipment for slag coolers is particularly important.

[0003] While traditional waste heat recovery devices for slag coolers achieve heat recovery to some extent, there is still room for improvement in heat transfer efficiency and equipment reliability. For example, some waste heat recovery designs in existing technologies can affect the normal operation of slag coolers, leading to problems such as scaling and blockage, resulting in decreased heat exchange efficiency and even affecting the service life of the equipment. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a waste heat recovery and efficiency enhancement heat exchange device for cold slag machine, which has the advantage of high heat recovery.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery and efficiency-enhancing heat exchange device for a cold slag machine, comprising an inner cylinder and an outer cylinder. One end of the circumferential side of the inner cylinder is connected to one side of the outer cylinder via a connecting ring. The other end of the outer surface of the inner cylinder is located inside the outer cylinder. The outer surface of the inner cylinder located outside the outer cylinder is connected to a drive motor via a conventional mechanism. The upper and lower ends of the connecting ring side are respectively provided with an outlet and an inlet. The outlet is connected to one end of an outlet pipe. The other end of the outlet pipe is connected to the inlet of a heating system via a water pump. The inlet is connected to one end of an inlet pipe via a solenoid valve. The other end of the inlet pipe is connected to an external water pipe.

[0006] As a preferred embodiment of this utility model, the inner cylinder is connected to a rotating shaft on the side inside the outer cylinder, the rotating shaft is rotatably connected to the inner wall of a rotating groove, and the rotating groove is disposed on the inner surface of the outer cylinder.

[0007] As a preferred technical solution of this utility model, the outer surface of the inner cylinder is provided with a plurality of guide blocks, the guide blocks are slidably connected to guide grooves, and the guide grooves are provided on the inner circumferential side of the outer cylinder.

[0008] As a preferred embodiment of this utility model, a transmission groove is provided on the outer surface of the inner cylinder, and the rotating groove is rotatably connected to the connecting ring.

[0009] As a preferred embodiment of this utility model, a sealing ring is bonded to the inner surface of the transmission groove, and the sealing ring is made of rubber.

[0010] As a preferred technical solution of this utility model, the inner surface of the inner cylinder is provided with multiple heat-conducting grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting an outer cylinder and placing the inner cylinder inside, can separate the inner and outer cylinders. This separation prevents the slag cooler from being affected during waste heat recovery, thus avoiding scaling, blockage, and other problems that could lead to decreased heat exchange efficiency and reduced equipment lifespan.

[0013] 2. This utility model can connect a rotating shaft to a rotating groove by setting a rotating shaft.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides a waste heat recovery and efficiency enhancement heat exchange device for a cold slag machine, including an inner cylinder 2 and an outer cylinder 1. One end of the circumferential side of the inner cylinder 2 is connected to one side of the outer cylinder 1 through a connecting ring 4. The other end of the outer surface of the inner cylinder 2 is located inside the outer cylinder 1. The outer surface of the inner cylinder 2 located outside the outer cylinder 1 is connected to a drive motor 3 through a conventional mechanism 19. The upper and lower ends of the side of the connecting ring 4 are respectively provided with a water outlet 11 and a water inlet 12. The water outlet 11 is connected to one end of a water outlet pipe 5. The other end of the water outlet pipe 5 is connected to the water inlet of a heating system 7 through a water pump 6. The water inlet 12 is connected to one end of a water inlet pipe 9 through a solenoid valve 10. The other end of the water inlet pipe 9 is connected to an external water pipe 8.

[0021] By setting up an outer cylinder 1 and placing an inner cylinder 2 inside it, the inner cylinder 2 and the outer cylinder 1 can be separated from each other. Tap water is then introduced into the area between the inner cylinder 2 and the outer cylinder 1 through the water inlet 12. When the inner cylinder 2 dissipates heat from the slag, the heat from the slag can be transferred through the shell of the inner cylinder 2 to the water in the area between the inner cylinder 2 and the outer cylinder 1. The water absorbs the heat, and after a period of absorption, the water pump 6 sends the heat-absorbed water into the heating system 7 for heating. The process involves using the water inlet 12 to introduce fresh tap water into the area between the inner cylinder 2 and the outer cylinder 1. By repeating this process, the heat from the slag cooler can be continuously absorbed. This not only effectively reduces heat waste but also reduces pollution emissions to some extent, improves energy efficiency, and separates the inner cylinder 2 from the outer cylinder 1. This prevents the slag cooler from being affected during waste heat recovery, thus avoiding problems such as scaling and blockage, which can lead to decreased heat exchange efficiency and reduced equipment lifespan.

[0022] The inner cylinder 2 is connected to a rotating shaft 14 on its side inside the outer cylinder 1. The rotating shaft 14 is rotatably connected to the inner wall of a rotating groove, which is located on the inner surface of the outer cylinder 1.

[0023] By setting a rotating shaft 14, it can be connected to a rotating groove. The stability of the inner cylinder 2 during rotation is improved by the limiting and guiding function of the rotating groove.

[0024] The inner cylinder 2 has multiple guide blocks 15 on its outer surface. The guide blocks 15 are slidably connected to guide grooves 13, which are located on the inner circumferential side of the outer cylinder 1.

[0025] By setting guide block 15, the stability of the inner cylinder 2 during rotation can be improved by limiting the movement through guide groove 13.

[0026] The inner cylinder 2 has a transmission groove 17 on its outer surface, and the rotation groove is rotatably connected to the connecting ring 4.

[0027] The inner surface of the transmission groove 17 is bonded with a sealing ring 18, which is made of rubber.

[0028] By setting a sealing ring 18, the sealing performance of the transmission groove 17 can be effectively improved, preventing water in the outer cylinder 1 and inner cylinder 2 from leaking out and affecting the heat absorption effect of the subsequent water.

[0029] The inner surface of the inner cylinder 2 is provided with a plurality of heat-conducting grooves 16.

[0030] By setting the heat conduction groove 16, the thickness of the inner cylinder 2 can be reduced without affecting the sealing of the inner cylinder 2, thereby improving heat transfer.

[0031] Working principle and usage process of this utility model:

[0032] By setting up an outer cylinder 1 and placing an inner cylinder 2 inside it, the inner cylinder 2 and the outer cylinder 1 can be separated from each other. Tap water is then introduced into the area between the inner cylinder 2 and the outer cylinder 1 through the water inlet 12. When the inner cylinder 2 dissipates heat from the slag, the heat from the slag can be transferred through the shell of the inner cylinder 2 to the water in the area between the inner cylinder 2 and the outer cylinder 1. The water absorbs the heat, and after a period of absorption, the water pump 6 sends the heat-absorbed water into the heating system 7 for heating. The process involves using the water inlet 12 to introduce fresh tap water into the area between the inner cylinder 2 and the outer cylinder 1. By repeating this process, the heat from the slag cooler can be continuously absorbed. This not only effectively reduces heat waste but also reduces pollution emissions to some extent, improves energy efficiency, and separates the inner cylinder 2 from the outer cylinder 1. This prevents the slag cooler from being affected during waste heat recovery, thus avoiding problems such as scaling and blockage, which can lead to decreased heat exchange efficiency and reduced equipment lifespan.
