Description

Technical Field

[0001] This utility model relates to the field of kiln pipeline technology, and in particular to a kiln heat energy balance pipeline mechanism. Background Technology

[0002] In traditional sintering equipment, the kiln usually supplies oxygen to the combustion zone by directly inputting cold air from the outside. However, this method can lead to a large temperature difference between different areas in the kiln (such as channel A and channel B), affecting the uniformity of the sintering temperature and causing problems such as asynchronous volatilization of adhesives and unstable sintering quality.

[0003] In response, some existing kilns attempt to heat the cold air first and then input it. While this can reduce the temperature difference between stage A and stage B to some extent, it consumes a lot of energy, and the heat in the cooling section of the sintering equipment is often wasted. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a kiln heat energy balancing pipeline mechanism, which solves the technical problem that existing kilns cannot effectively utilize the heat in the cooling section, resulting in a large temperature difference between channel A and channel B, which adversely affects the sintering quality of the product.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a kiln heat energy balance pipeline mechanism, including a sintering device. The sintering device has an internal kiln channel A and a kiln channel B. Electric heaters and material conveying tracks are respectively installed inside kiln channel A and kiln channel B. A circulating fan is installed on the side of kiln channel A, and an exhaust pipe connects the circulating fan to kiln channel A. An intake pipe connects the intake end of the circulating fan to the intake end of the circulating fan. During the sintering process of the product inside kiln channels A and B, the circulating fan will pass through the exhaust pipe... Air is introduced into the interior of channel A inside the kiln through the inlet pipe, thereby ensuring the normal operation of the sintering process. The inlet pipe is equipped with a heat energy circulation mechanism for conveying the heat energy of the cooling section of the sintering equipment. The heat energy circulation mechanism includes a connecting component. One side of the connecting component is equipped with a main exhaust pipe that communicates with the inlet pipe, and the other side of the connecting component is equipped with a branch inlet pipe. The branch inlet pipe is covered with an insulation sleeve, and the insulation sleeve is covered with an outer protective sleeve. When the circulating fan is powered on, it will draw the hot air inside the branch inlet pipe into the interior of channel A inside the kiln, thereby promoting combustion.

[0006] Preferably, several branch air inlets are evenly spaced, which can improve the efficiency of heat transfer, realize multi-point heat transfer, and allow for cyclic maintenance of the pipeline without stopping the machine.

[0007] Preferably, the branch air intake pipe is rotatably connected to an inclined baffle, and a water collection box is detachably installed on the outside of the branch air intake pipe. Initially, the inclined baffle covers the inside of the branch air intake pipe. During heat transfer, the inclined baffle will rotate upward under the action of the circulating fan.

[0008] Preferably, the insulation sleeve is made of polyurethane foam, which can effectively reduce heat loss during heat transfer.

[0009] Preferably, the branch air intake pipe is made of stainless steel, and the outer protective sleeve is made of polyethylene material. The outer protective sleeve can provide a certain degree of protection to the insulation sleeve and prevent damage to the insulation sleeve.

[0010] By employing the above technical solution, this utility model provides a kiln heat energy balancing pipeline mechanism, which has at least the following beneficial effects:

[0011] 1. This utility model, by setting up a circulating fan and a heat energy circulation mechanism, re-transports the hot air from the cooling section of the sintering equipment to channel A inside the kiln, so that the incoming air is in a high-temperature state. Compared with directly inputting cold air from the outside, this significantly reduces the temperature difference between channel A and channel B inside the kiln. This not only optimizes the temperature uniformity of the sintering process, but also reduces heat loss and improves energy utilization, thereby reducing overall energy consumption.

[0012] 2. This utility model, by setting up a circulating fan and a heat energy circulation mechanism, inputs preheated air from the side, and combines the synergistic effect of the electric heater and the material conveying track to ensure uniform temperature distribution during sintering, avoiding local overheating or overcooling. This stable thermal environment allows the product adhesive to volatilize simultaneously, thereby reducing sintering defects, improving the density and mechanical properties of the product, and ensuring the consistency of sintered product quality.

[0013] 3. By setting up connecting components and branch air inlets, the branch air inlets are arranged in multiple groups at equal intervals to form a multi-point heat absorption and heat transfer network. This not only improves the heat transfer efficiency, but also enables rotational maintenance without downtime, greatly reducing production interruption time. In addition, the design of the inclined baffle and water collection box can automatically collect condensate, prevent pipe blockage or corrosion, extend the service life of the equipment, and reduce maintenance costs.

[0014] 4. This utility model features an insulated sleeve and an outer protective sleeve. The intake pipe is made of stainless steel, and the outer protective sleeve is made of polyethylene, which has both high temperature resistance and corrosion resistance. At the same time, the insulated sleeve can effectively reduce heat loss. The overall structure takes into account thermal efficiency, safety and durability. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] In existing technologies, some kilns attempt to preheat cold air before introducing it into the furnace. While this can reduce the temperature difference between stages A and B to some extent, it consumes a lot of energy, and the heat from the cooling section of sintering equipment 1 is often wasted. To address this technical deficiency in existing technologies, such as... Figures 1-6As shown, this embodiment proposes a kiln heat energy balance pipeline mechanism, which can significantly reduce the temperature difference between kiln channel A2 and kiln channel B3. Specifically, the sintering equipment 1 has kiln channel A2 and kiln channel B3. Electric heaters 4 and material conveying tracks 5 are respectively installed inside kiln channel A2 and kiln channel B3. A circulating fan 6 is installed on the side of kiln channel A2. An exhaust pipe 7 connects the circulating fan 6 to kiln channel A2. An air inlet pipe 8 connects the air inlet end of the circulating fan 6. During the sintering process of the product inside kiln channel A2 and kiln channel B3, the circulating fan 6 will input air into kiln channel A2 through the exhaust pipe 7, thereby ensuring the normal operation of the sintering operation.

[0026] Specifically, the intake pipe 8 is equipped with a heat energy circulation mechanism 9 for conveying heat energy from the cooling section of the sintering equipment 1. The heat energy circulation mechanism 9 includes a connecting component 901. One side of the connecting component 901 is equipped with a main exhaust pipe 902 that communicates with the intake pipe 8, and the other side of the connecting component 901 is equipped with a branch intake pipe 903. The branch intake pipes 903 are made of stainless steel, and several branch intake pipes 903 are evenly spaced, which can improve the efficiency of heat transfer, realize multi-point heat transfer, and also allow for cyclic maintenance of the pipeline without stopping the machine. The branch intake pipes 903 are covered with an insulation sleeve 904, which is made of polyurethane foam, and can effectively reduce the heat transfer process. To reduce heat loss, an outer protective sleeve 905 is fitted around the insulation sleeve 904. When the circulating fan 6 is powered on, it draws the hot air inside the branch air inlet pipe 903 into the interior of kiln A channel 2, thereby promoting combustion. The outer protective sleeve 905 is made of polyethylene material and can provide a certain degree of protection for the insulation sleeve 904 to prevent damage. An inclined baffle 906 is rotatably connected inside the branch air inlet pipe 903, and a water collection box 907 is detachably installed on the outside of the branch air inlet pipe 903. Initially, the inclined baffle 906 covers the inside of the branch air inlet pipe 903. During heat transfer, the inclined baffle 906 will rotate upward under the action of the circulating fan 6.

[0027] As can be seen from the above, during the sintering process of the product, the circulating fan 6 will automatically transfer the heat generated by the cooling section of the sintering equipment 1 to the interior of the conveying kiln A channel 2 through the branch air inlet pipe 903, so that the air entering the kiln A channel 2 is in a high temperature state. Compared with the existing technology of directly conveying the outside air to the kiln A channel 2, it can effectively reduce the temperature difference between the kiln A channel 2 and the kiln B channel 3, and ensure that the product adhesive volatilization can be carried out simultaneously.

[0028] Moreover, such as Figure 1As shown, multiple branch air inlets 903 are provided, which can set multiple heat absorption points near the cooling end of the sintering equipment 1, effectively improving the efficiency of heat transfer, thereby ensuring the normal operation of the sintering process. In addition, multiple branch air inlets 903 can be inspected and maintained in turn without stopping the machine.

[0029] In addition, such as Figure 6 As shown, each branch air intake pipe 903 is equipped with an inclined baffle 906. After the circulating fan 6 stops working, the inclined baffle 906 will tilt and block the inside of the branch air intake pipe 903. Then, the condensate generated on the inner wall of the branch air intake pipe 903 will flow down the inner wall of the pipe. Subsequently, the condensate will flow into the water collection box 907 under the action of the inclined baffle 906.

[0030] This embodiment, by setting up a circulating fan 6 and a heat circulation mechanism 9, re-transports the hot air from the cooling section of the sintering equipment 1 back to channel A 2 inside the kiln. This ensures the incoming air is at a high temperature, significantly reducing the temperature difference between channel A 2 and channel B 3 compared to directly inputting cold outside air. This not only optimizes the temperature uniformity of the sintering process but also reduces heat loss and improves energy utilization, thereby reducing overall energy consumption. Furthermore, by using the circulating fan 6 and heat circulation mechanism 9 to input preheated air from the side, combined with the synergistic effect of the electric heater 4 and the material conveying track 5, this embodiment ensures uniform temperature distribution during sintering, avoiding localized overheating or overcooling. This stable thermal environment allows for simultaneous evaporation of the adhesive in the product, reducing sintering defects, improving the density and mechanical properties of the product, and ensuring... The sintered products exhibit consistent quality. Furthermore, this embodiment, by setting up a connecting component 901 and a branch air inlet pipe 903, with multiple sets of equally spaced branch air inlet pipes 903 forming a multi-point heat absorption and heat transfer network, not only improves heat transfer efficiency but also enables alternating maintenance without downtime, significantly reducing production interruption time. In addition, the design of the inclined baffle 906 and water collection box 907 can automatically collect condensate, preventing pipe blockage or corrosion, extending equipment lifespan, and reducing maintenance costs. Moreover, this embodiment, by setting up an insulation sleeve 904 and an outer protective sleeve 905, with the branch air inlet pipe 903 made of stainless steel and the outer protective sleeve 905 made of polyethylene, combines high temperature resistance and corrosion resistance. At the same time, the insulation sleeve 904 can effectively reduce heat loss. The overall structure takes into account thermal efficiency, safety, and durability.
