[0001] This application relates to the field of rotary kiln equipment technology, and in particular to a temperature control and energy-saving device for rotary kiln systems. Background Technology

[0002] In industrial production, rotary kilns, as a core piece of equipment that achieves high-temperature material processing through a rotating cylinder, are widely used in various fields such as cement clinker calcination, metallurgical ore roasting, and chemical raw material sintering. Temperature control of the rotary kiln system plays a crucial role in product quality and production efficiency. The temperature inside the kiln needs to be precisely maintained within the range of 800-1600℃ according to different process requirements.

[0003] Existing rotary kiln systems have many problems with temperature control, such as insufficient temperature precision and large temperature fluctuations. This not only affects the stability of product quality but may also lead to energy waste during the production process. To address these issues, we propose a temperature control and energy-saving device for rotary kiln systems. Utility Model Content

[0004] The purpose of this application is to provide a temperature control and energy-saving device for rotary kiln systems to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A temperature control and energy-saving device for a rotary kiln system includes a rotary kiln body. An electric heating coil is installed inside the feed end of the rotary kiln body. A temperature monitor is installed on the top of the rotary kiln body. A spiral tube is installed inside the discharge end of the rotary kiln body. A cooling box is installed outside the rotary kiln body. The output end and input end of the spiral tube are both connected to the outer surface of the cooling box, and the input end of the spiral tube extends into the interior of the cooling box and is connected to a submersible pump.

[0007] In a further embodiment, a sealing plate is fixedly connected to the inner wall of the cooling box, and a set of baffles and a set of partitions are fixedly connected to the upper surface of the sealing plate. A water leakage groove is formed on the upper surface of the sealing plate.

[0008] In a further embodiment, a set of fans is embedded on the upper surface of the cooling box, and each fan is provided with a protective cover.

[0009] In a further embodiment, a support plate is fixedly connected to the bottom surface of the cooling box, and the other end of the support plate is connected to the outer surface of the rotary kiln body.

[0010] In a further embodiment, the exhaust end of the rotary kiln body is connected to a heat exchange box, the heat exchange box is provided with heat exchange tubes, and one side of the heat exchange box is connected to an exhaust pipe.

[0011] In a further embodiment, a station plate is fixedly connected to the bottom surface of the heat exchange box, and the bottom end of the station plate is connected to the outer surface of the rotary kiln body.

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

[0013] This application utilizes a combination of a spiral tube, a cooling tank, and a submersible pump. The submersible pump draws water from inside the cooling tank into the spiral tube, where the flowing water absorbs heat from the rotary kiln body, thus controlling the kiln and ensuring product quality stability. Furthermore, the combination of a sealing plate, baffles, and a fan allows the baffles and baffles to guide the heat-absorbing water, while the fan cools it further, reducing the temperature of the water leaking into the bottom of the cooling tank and enabling continuous water utilization.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[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] Please see Figure 1-3 In this utility model, a temperature control and energy-saving device for a rotary kiln system is provided. An electric heating coil 4 is installed inside the feed end of the rotary kiln body 1, and a temperature monitor 9 is installed on the top of the rotary kiln body 1. The electric heating coil 4 can be used to heat the feed end of the rotary kiln body 1. By controlling the working state of the electric heating coil 4, the temperature of the feed end of the rotary kiln body 1 can be adjusted. At the same time, the temperature monitor 9 can be used to monitor the internal temperature of the rotary kiln body 1 in real time.

[0021] The exhaust end of the rotary kiln body 1 is connected to a heat exchange box 7. The heat exchange box 7 is equipped with heat exchange tubes 8. One side of the heat exchange box 7 is connected to an exhaust pipe 6. The flue gas inside the rotary kiln body 1 will directly enter the heat exchange box 7. Then, water will be injected into the heat exchange tubes 8. When the flue gas flows inside the heat exchange box 7, it will transfer heat to the water inside the heat exchange tubes 8, thereby achieving the effect of waste heat utilization. A station plate 5 is fixedly connected to the bottom surface of the heat exchange box 7. The bottom end of the station plate 5 is connected to the outer surface of the rotary kiln body 1. The station plate 5 can stably support the heat exchange box 7 and keep it in a firm state.

[0022] A spiral tube 10 is installed inside the discharge end of the rotary kiln body 1, and a cooling box 2 is installed outside the rotary kiln body 1. The output end and input end of the spiral tube 10 are both connected to the outer surface of the cooling box 2, and the input end of the spiral tube 10 extends into the interior of the cooling box 2 and is connected to a submersible pump 15. When temperature adjustment is required, the submersible pump 15 is controlled to work, and the submersible pump 15 will draw water into the spiral tube 10. When the water flows inside the spiral tube 10, it can absorb heat inside the rotary kiln body 1, thereby controlling the internal temperature of the rotary kiln body 1 and ensuring the stability of product quality. A support plate 3 is fixedly connected to the bottom surface of the cooling box 2, and the other end of the support plate 3 is connected to the outer surface of the rotary kiln body 1. The support plate 3 can be used to support the cooling box 2 outside the rotary kiln body 1.

[0023] A sealing plate 16 is fixedly connected to the inner wall of the cooling box 2. A set of baffles 17 and a set of partitions 14 are fixedly connected to the upper surface of the sealing plate 16. A water leakage groove 13 is opened on the upper surface of the sealing plate 16. The sealing plate 16 can block the water flowing back into the cooling box 2. At the same time, the baffles 17 and partitions 14 will guide the water, allowing the water to flow from the water leakage groove 13 to the bottom of the cooling box 2. A set of fans 12 is embedded on the upper surface of the cooling box 2. Each fan 12 is equipped with a protective cover 11. The fans 12 can blow air to cool the water on the sealing plate 16, thereby reducing the water temperature and facilitating the reuse of water. At the same time, the protective cover 11 can block impurities to prevent them from entering the water.

[0024] The working principle of this application is as follows: During use, the temperature monitor 9 monitors the internal temperature of the rotary kiln body 1 in real time, and the heating temperature of the electric heating coil 4 can be adjusted through the control panel. When the monitored temperature value is high, the control panel will start the submersible pump 15, and the cooling water inside the cooling tank 2 will be drawn into the spiral tube 10 to absorb heat inside the rotary kiln body 1, thereby achieving the temperature control effect. The water after absorbing heat will flow to the sealing plate 16, and will be guided by the baffle 17 and the partition 14 to flow downward from the drain trough 13, thereby accurately adjusting the internal temperature of the rotary kiln body 1 and ensuring the stability of product quality.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
