Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology; specifically, it relates to an infrared electric heater for a precision aeration system. Background Technology
[0002] Temperature is a crucial control parameter in the aeration process of wastewater treatment. If the water temperature is low, it may be necessary to extend the aeration time or increase the aeration volume to ensure that microorganisms have sufficient oxygen for metabolism. In the high temperatures of summer, care must be taken to prevent excessively high water temperatures from damaging the microorganisms, in order to maintain a suitable survival temperature for them and ensure the efficient operation of the aeration process. This allows the microorganisms to effectively decompose organic matter in the wastewater, achieving good wastewater treatment results.
[0003] Electric heaters, as the core component of electric heating water temperature control systems, come in various types, each with its own characteristics and applicable scenarios. Common electric heaters include resistance electric heaters, electromagnetic electric heaters, and infrared electric heaters.
[0004] Infrared electric heaters transfer heat through infrared radiation, resulting in a more uniform heating process that effectively avoids localized overheating. They also possess a certain degree of sterilization and disinfection, making them suitable for special wastewater treatment scenarios with high water quality and hygiene requirements. However, in conventional methods, the quartz tube of the infrared electric heater is directly fixed to the baffle plate. During operation, the quartz tube is highly susceptible to deformation under thermal stress, which can easily lead to bursting. Utility Model Content
[0005] In view of this, the present invention provides an infrared electric heater for a precision aeration system, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.
[0006] To achieve the aforementioned objectives, this utility model provides an infrared electric heater for a precision aeration system, comprising a housing, on which a quartz tube is mounted. Baffles are equidistantly sleeved around the outside of the quartz tube along its length. A pull rod, passing sequentially through all the baffles, is mounted on the housing to stabilize the baffles. The pull rod is rotatably engaged with the housing and slidably engaged with the baffles. A fixed sleeve, fitted over the quartz tube, is fixedly mounted inside each baffle. A telescopic connecting sleeve is located at the front end of the fixed sleeve. The fixed portion of the connecting sleeve is fixedly connected to the fixed sleeve. A pull plate, fitted over the quartz tube, is fixedly connected to the front end of the movable portion of the connecting sleeve. Multiple centrally symmetrically distributed elastic clips are mounted inside the fixed sleeve. These elastic clips clamp the outside of the quartz tube and are slidably engaged with the movable portion. When the movable portion moves backward, it compresses the elastic clips towards the center of the quartz tube. The pull rod is threadedly engaged with the pull plate, enabling control of the pull plate's displacement along the length of the quartz tube.
[0007] In the infrared electric heater of the precision aeration system described above, optionally, the fixed part includes an inner sleeve whose inner diameter is adapted to the inner diameter of the fixed sleeve and an outer sleeve fixedly sleeved outside the inner sleeve. The front end of the outer sleeve is open. The rear end of the movable part is slidably disposed between the outer surface of the inner sleeve and the inner wall surface of the outer sleeve. The elastic clip is located in the cavity of the movable part. The front end of the movable part is slidably sleeved outside the front end of the inner sleeve.
[0008] In the infrared electric heater of the precision aeration system described above, optionally, the elastic clip includes an arc-shaped clip, a spring and a slider. The arc-shaped clip clamps the quartz tube, and the two ends of the spring are respectively connected to the arc-shaped clip and the slider. The inner wall of the movable part is a conical surface with the front end inclined downward, and the slider slides in cooperation with the inner wall of the movable part.
[0009] In the infrared electric heater of the precision aeration system described above, optionally, the inner side of the slider is provided with a rod that is inserted into the spring cavity, and the outer side of the arc-shaped clamp is provided with a slot, and the inner end of the rod is inserted into the slot.
[0010] In the infrared electric heater of the precision aeration system described above, optionally, a through groove is provided on the inner sleeve, the arc-shaped clamp is located in the through groove, and the arc-shaped clamp is adapted to the size of the through groove.
[0011] The infrared electric heater of this invention uses a pull rod to drive the pull plate to move, which in turn drives the movable part to move. The movable part then applies pressure to the arc-shaped clamping piece, which compresses the arc-shaped clamping piece and increases the clamping force on the quartz tube. This allows for adjustment of the clamping force on the quartz tube and better adaptation to the deformation of the quartz tube under thermal stress. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] like Figures 1 to 3 As shown, this utility model provides an infrared electric heater for a precision aeration system, including a housing 1. A quartz tube 2 is disposed on the housing 1. Baffles 3 are equidistantly sleeved on the outside of the quartz tube 2 along its length. A pull rod 4 is disposed on the housing 1, passing through all the baffles 3 in sequence, for stabilizing the baffles 3. The pull rod 4 is rotatably engaged with the housing 1 and slidably engaged with the baffles 3. A fixing sleeve 5 is fixedly disposed inside the baffles 3 and sleeved on the outside of the quartz tube 2. The front end of the fixing sleeve 5 is provided with a telescopic connector. The connecting sleeve has a fixed part that is fixedly connected to the fixed sleeve 5. The front end of the movable part 6 of the connecting sleeve is fixedly connected to a pull plate 7 that is sleeved on the outside of the quartz tube 2. The fixed sleeve 5 has a plurality of elastic clips that are centrally symmetrically distributed inside. The elastic clips are clamped on the outside of the quartz tube 2 and are configured to slide with the movable part 6. When the movable part 6 moves backward, it compresses the elastic clips toward the center of the quartz tube 2. The pull rod 4 is threadedly engaged with the pull plate 7, which can control the displacement of the pull plate 7 in the length direction of the quartz tube 2.
[0019] By rotating the pull rod 4, the pull plate 7 is displaced rearward. The pull plate 7 causes the movable part 6 to move rearward within the fixed part. At this time, the pull plate 7 increases the clamping force of the elastic clip on the quartz tube 2 by compressing the elastic clip. Therefore, during equipment debugging, the clamping force of the elastic clip on the quartz tube 2 can be adjusted according to the vibration conditions, ensuring the equipment reaches a good working state. Simultaneously, the elastic properties of the elastic clip can better adapt to the deformation of the quartz tube 2 under thermal stress.
[0020] The fixed part includes an inner sleeve 8 whose inner diameter matches the inner diameter of the fixed sleeve 5, and an outer sleeve 9 of the fixed sleeve 5 located outside the inner sleeve 8. The front end of the outer sleeve 9 is open. The rear end of the movable part 6 is slidably disposed between the outer surface of the inner sleeve 8 and the inner wall surface of the outer sleeve 9. An elastic clip is located in the cavity of the movable part 6, and the front end of the movable part 6 is slidably sleeved outside the front end of the inner sleeve 8. In this embodiment, the inner sleeve 8 and the outer sleeve 9, together with the movable part 6, can form a relatively closed area, improving the stability of the elastic clip.
[0021] Specifically, the elastic clamp includes an arc-shaped clamp 10, a spring 11, and a slider 12. The arc-shaped clamp 10 clamps the quartz tube 2. The two ends of the spring 11 are connected to the arc-shaped clamp 10 and the slider 12, respectively. The inner wall of the movable part 6 is a conical surface with a downward-sloping front end, and the slider 12 slides in conjunction with the inner wall of the movable part 6. In this embodiment, when the movable part 6 moves backward, its inner wall slides outside the slider 12 while compressing the slider 12 inward, causing the slider 12 to compress the spring 11, thereby increasing the clamping force of the arc-shaped clamp 10 on the quartz tube 2.
[0022] The inner side of the slider 12 is provided with a rod 13 that inserts into the cavity of the spring 11, and the outer side of the arc-shaped clamp 10 is provided with a slot 14, the inner end of the rod 13 being inserted into the slot 14. By providing the rod 13 and the slot 14, the spring 11 will not twist during the displacement and compression of the movable part 6, ensuring that the spring 11 can stably apply force to the arc-shaped clamp 10.
[0023] The inner sleeve 8 has a through groove 15, and the arc-shaped clamping piece 10 is located in the through groove 15, and the size of the arc-shaped clamping piece 10 is adapted to the through groove 15. The through groove 15 can limit the arc-shaped clamping piece 10 and improve the stability of the arc-shaped clamping piece 10.
[0024] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
