Description

Technical Field

[0001] This utility model relates to the field of waste heat utilization of chlorination furnace body, and in particular to a device for utilizing waste heat of chlorination furnace body for high-purity quartz sand. Background Technology

[0002] In the production process of high-purity quartz sand, the chlorination furnace is a key piece of equipment. With the continuous growth of market demand for high-purity quartz sand, the operating scale and frequency of chlorination furnaces are also gradually increasing. However, during the operation of the chlorination furnace, a large amount of heat energy is lost in the form of waste heat. If this waste heat cannot be effectively utilized, it will not only waste energy but also increase production costs and cause certain thermal pollution to the environment.

[0003] Traditional methods of utilizing waste heat from chlorination furnaces often involve simply installing a heat exchange device on the outside of the furnace, such as a common jacketed water tank.

[0004] While this method can absorb the waste heat of the furnace to some extent, the heat exchange efficiency is low because the water flows relatively steadily in the water tank and the heat exchange mainly relies on natural convection. The heat transfer between the water and the furnace wall is not sufficient. Therefore, a waste heat utilization device for chlorination furnaces using high-purity quartz sand is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a waste heat utilization device for a chlorination furnace body for high-purity quartz sand, which aims to improve the problem in the prior art that "the heat exchange efficiency is low because the water flow in the water tank is relatively stable".

[0032] 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.

[0033] Reference Figure 1 and Figure 2This utility model provides an embodiment of a waste heat utilization device for a chlorination furnace body for high-purity quartz sand, including a support frame 1 for supporting an outer shell 2. The support frame 1 has an outer shell 2 at its top, which is the shell of the chlorination furnace and plays a key role in the chlorination process of high-purity quartz sand, while generating a large amount of waste heat. This technology is prior art, so it will not be described in detail. A water tank 3 is snapped onto the outside of the outer shell 2, mainly for absorbing the waste heat of the outer shell 2. It is attached to the outside of the outer shell 2 so that the water can fully absorb the heat. A water inlet pipe is provided on the upper side of the water tank 3, and a water outlet pipe is provided on the lower side of the water tank 3. The water inlet pipe on the upper side is used to inject water into the water tank 3, and the water outlet pipe on the lower side can lead out the heated water for subsequent use.

[0034] Furthermore, an insulation shell 4 is provided on the outside of the water tank 3 to reduce heat exchange between the hot water inside the water tank 3 and the external environment, and to prevent heat from being lost to the surrounding environment too quickly. A turbulence mechanism is provided on the upper side of the support frame 1. The turbulence mechanism includes a turbulence component and an auxiliary component. The turbulence component includes a mounting plate 51, which serves to support and fix the drive motor 52. The bottom end of the mounting plate 51 is fixedly connected to the top of the outer shell 2. The drive motor 52 is fixedly connected to the outside of the mounting plate 51 as a power source. The rotation of its output shaft provides power for the rotation of the turbulence plate 56. When the drive motor 52 is working, the rotation of the output shaft drives the swing arm 53 to move, so that the turbulence plate 56 can move up and down in the water tank 3. The output shaft of the drive motor 52 passes through the mounting plate 51.

[0035] Reference Figure 3 and Figure 4 A swing arm 53 is fixedly connected to the rear side of the output shaft of the drive motor 52, connecting the output shaft of the drive motor 52 and the limiting bar 55. This transmits the rotational motion of the drive motor 52 to the limiting bar 55, thereby driving the connecting rod 54 and the spoiler 56 to move up and down. Simultaneously, its rear side slides against the inner wall of the limiting bar 55, ensuring the accuracy and stability of the movement. A connecting rod 54 is slidably connected to the inner wall of the water tank 3, connecting the limiting bar 55 and the spoiler 56, serving to transmit motion. When the limiting bar 55 moves under the drive of the swing arm 53, the connecting rod 54... The rod 54 can transmit motion to the baffle 56, causing the baffle 56 to move up and down inside the water tank 3. The top of the connecting rod 54 is fixedly connected to the limit strip 55, which is hollow at the front and back and can be connected to the swing arm 53. The rear side of the swing arm 53 slides on the inner wall of the limit strip 55. The baffle 56 is fixedly connected to the lower outer side of the connecting rod 54. When it moves, it can change the flow state of the water in the water tank 3, so that the water forms a turbulence. The turbulence can enhance the heat exchange between the water and the wall of the water tank 3 and the inside of the water, allowing the water to absorb the heat transferred from the outer shell 2 more fully.

[0036] Reference Figure 4 and Figure 5The auxiliary components include a stabilizing rod 61, which guides and stabilizes the swing of the spoiler 56, ensuring that the spoiler 56 maintains the correct position and direction during the swing, preventing the spoiler 56 from shaking or shifting inside the water tank 3, thereby ensuring the stability and reliability of the turbulence effect. The stabilizing rod 61 is vertically fixed to the inner wall of the water tank 3, and the front inner wall of the spoiler 56 is slidably connected to the outside of the stabilizing rod 61. The outer side of the spoiler 56 has through holes 62, and multiple sets of through holes 62 are provided to allow water to pass through during the movement of the spoiler 56, further increasing the water flow and heat exchange effect. The lower side of the water tank 3 slides on the upper side of the support frame 1, and the upper side of the water tank 3 slides on the upper inner side of the outer shell 2, limiting the vertical movement of the water tank 3. The spoiler 56 and the water tank 3 are set in a U-shape, and multiple sets of spoilers 56 are provided. The U-shaped water tank 3 cooperates with the outer shell 2 to limit the horizontal movement of the water tank 3.

[0037] Reference Figure 1 and Figure 6 The front side of the outer casing 2 is provided with an installation component, which includes a fixing block 71, providing a sliding track for the limiting plate 72. Together with the compression spring 73, the limiting plate 72 can move within a certain range and remain in its initial position when no external force is applied. The fixing block 71 is fixedly connected to the front side of the outer casing 2. The limiting plate 72 is slidably connected to the inner wall of the fixing block 71 and is inserted into the fixing frame 74 on the front side of the water tank 3 to realize the connection and fixation of the outer casing 2 and the water tank 3. When it is necessary to disassemble the water tank 3, an external force can be applied to make the limiting plate 72 squeeze the compression spring 73 and disengage from the fixing frame 74, which facilitates the maintenance or replacement of the water tank 3. The limiting plate 72 and the fixing block 71 are elastically connected by the compression spring 73.

[0038] Furthermore, one end of the compression spring 73 is fixedly connected to the inner wall of the fixing block 71, and the other end of the compression spring 73 is fixedly connected to the left side of the limiting plate 72, providing elastic force so that the limiting plate 72 can return to its original position after being free from external force or after the external force disappears, ensuring the tight insertion of the limiting plate 72 and the fixing frame 74, thereby ensuring the stability of the connection between the outer shell 2 and the water tank 3. The front side of the water tank 3 is fixedly connected to the right side near the fixing block 71, and the limiting plate 72 is inserted into the inner wall of the fixing frame 74 for insertion with the limiting plate 72. Through the cooperation with the limiting plate 72, the connection between the water tank 3 and the outer shell 2 is realized, so that the water tank 3 can be stably snapped onto the outside of the outer shell 2, and is convenient for installation and disassembly.

[0039] Working principle: When in use, water is injected into the water tank 3 through the water injection pipe. When the drive motor 52 is working, its output shaft starts to rotate, driving the swing arm 53 to make a circular motion. The movement of the swing arm 53 is transmitted to the connecting rod 54 through the limit bar 55, causing the connecting rod 54 to slide up and down on the inner wall of the water tank 3. With the movement of the connecting rod 54, the baffle 56 moves up and down in the water tank 3.

[0040] When the baffle 56 moves, it changes the flow state of the water in the water tank 3, causing the water to form turbulence, which enhances the heat exchange between the water and the wall of the water tank 3 and the interior of the water. During the turbulence process, water at different temperature layers can mix more fully, so that the heat can be distributed more evenly in the water, allowing the water to absorb the heat transferred from the outer shell 2 more fully.

[0041] During the movement of the spoiler 56, the stabilizer bar 61 guides and stabilizes the movement of the spoiler 56, preventing the spoiler 56 from shaking or shifting in the water tank 3. When the spoiler 56 moves, water can pass through these through holes 62 during the movement of the spoiler 56, further increasing the water flow and heat exchange effect.

[0042] When the water tank 3 needs to be disassembled and maintained, the operator needs to apply external force to the limiting plate 72 to overcome the elastic force of the compression spring 73. The limiting plate 72 will slide along the inner wall of the fixing block 71. After the limiting plate 72 is completely separated from the fixing frame 74, the connection between the water tank 3 and the outer shell 2 is released. At this time, the water tank 3 can be removed from the outside of the outer shell 2 for maintenance.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
