Description

Technical Field

[0001] The utility model relates to the field related to deaerators, in particular to an isolation and protection device for a deaerator. Background Art

[0002] In industrial production processes, particularly in the power, chemical, and metallurgical industries, controlling water quality in boiler water supply and circulating water systems is crucial for ensuring long-term, stable equipment operation and improving production efficiency. Removing dissolved oxygen from water is a crucial measure for preventing metal corrosion, reducing scale formation, and improving heat transfer efficiency. With the continuous advancement of industrial technology and increasingly stringent environmental protection requirements, the performance requirements for deaerators are also becoming increasingly stringent. Deaerators must not only have high deoxygenation efficiency but also demonstrate excellent durability, safety, and environmental friendliness.

[0003] Currently, common deaerators on the market are categorized into thermal deaerators, vacuum deaerators, and chemical deaerators. Vacuum deaerators, due to their high efficiency, energy-saving, and environmentally friendly features, are widely used in industrial production. Vacuum deaerators reduce the pressure within the water system, causing the water to boil below its boiling point, thereby releasing dissolved oxygen.

[0004] From the perspective of the deaerator's operating temperature, it is significantly necessary to set up a protective structure: first, the protective structure can serve as an insulating layer to reduce the heat exchange between the deaerator and the external environment, thereby reducing the thermal stress of the deaerator's internal materials and preventing material deformation or failure due to excessive thermal stress; second, the deaerator's operating temperature is relatively high, avoiding safety hazards caused by working equipment or staff touching it.

[0005] For example, the Chinese authorized patent with announcement number CN 220169433 U (an isolation and protection device for a deaerator) has a protective mechanism provided at the top of the base near the deaerator body. The protective mechanism includes a drive motor, the output shaft of the drive motor is connected to a bidirectional threaded rod through a first synchronous belt transmission, and both ends of the outer wall of the bidirectional threaded rod are threadedly connected to a threaded sleeve, and both ends of the top of the base near the deaerator body are provided with a protective shell. The utility model protects the outer wall of the deaerator body by driving the protective shell by the drive motor in the protective mechanism, avoiding the occurrence of burns caused by accidental collision between the surrounding personnel and the deaerator body when the deaerator body generates high temperature in the working state. The surrounding working environment is effectively protected when the deaerator body is working, thereby improving the safety of the device during use.

[0006] Although the above-mentioned existing technology has a protective function, the protective structure is closed by the drive of the threaded structure. The threaded connection has high movement accuracy, which can reduce the impact on the middle connection position when the two parts of the structure are closed, and can avoid the impact on the deaerator body structure. However, it is precisely because of the high movement accuracy of the threaded connection method that the movement path is increased, the movement time is increased, and it takes a long time to install the protective structure.

[0011] Preferably, a lower C-shaped fixing seat is fixed in the middle of both sides of the upper end of the support platform, and the lower C-shaped fixing seat is connected to a driving hydraulic cylinder through an axial rotation, and the output rod end of the driving hydraulic cylinder is connected to a side fixing block through an axial rotation, and the side fixing block is fixed to the upper end of the outer side of the side protective shell.

[0012] Preferably, a driving motor is installed at the front end of one side of the lower end of the support platform, and the front and rear ends of the lower end of the support platform are both installed with third transmission wheels through connecting vertical plates. The two third transmission wheels are connected through a second transmission belt, and the output shaft end of the driving motor is connected to the third transmission wheel at the front end.

Furthermore, the heat insulation cavity within the inner wall of the side protective shell, the upper protective shell, and the lower connecting shell of the outer protective shell plays an insulating role, reducing the heat exchange between the deaerator body and the outside world, effectively maintaining the internal temperature of the equipment, improving energy utilization, and reducing energy consumption losses. This partial structure achieves two-way protection, which not only protects staff but also ensures the operating efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-7 The present invention provides an embodiment of a support platform 1, with high-strength support legs 2 fixed to both sides of its lower end to ensure overall stability. A rectangular through-slot 3 is defined in the center of the support platform 1, allowing the support legs of the deaerator body 6 to pass through seamlessly and directly contact the ground. Furthermore, a side through-slot 5, extending from front to back, is designed on one side of the upper end surface of the support platform 1 to reserve space for the subsequent transmission belt to pass through.

[0030] Furthermore, an outer protective shell 7 is installed on both sides of the upper end of the support platform 1. Holes or sliding grooves are provided in the outer protective shell 7 and are located at the position of the pipes of the deaerator body 6. When the outer protective shell 7 is slidably installed, it does not affect the position of the upper end pipes or the connection between the side pipes and the outside world. The shell includes side protective shells 8, an upper protective shell 9, and a lower connecting shell 10. The three are tightly connected to form a complete protective cover.

[0031] A driving sliding block 17 is installed inside the front and rear ends of the side protection shell 8, and its inner wall is provided with an internal thread 24, which provides a solid foundation for subsequent thread transmission.

[0032] At the same time, fixed vertical plates 14 are fixed on the front and rear sides of the upper end of the support platform 1, and a smooth round rod 15 is rotatably connected between the two fixed vertical plates 14, and a bidirectional threaded rod 16 is fixed in the middle section of the smooth round rod 15. The bidirectional threaded rod 16 has the same tooth shape, diameter and pitch as the internal thread 24 on the driving sliding block 17, ensuring that it matches the internal thread 24 of the driving sliding block 17 to achieve precise transmission.

[0033] Furthermore, a lower connecting plate 11 is fixed to the outer side of the lower end of the upper and lower connecting shells 10 of the outer protective shell 7. A limit sliding block 12 is integrally connected to the middle of the lower end of the lower connecting plate 11. A limit sliding groove 4 is provided in the middle of both sides of the upper end surface of the support platform 1. A lower C-shaped fixing seat 25 is installed at the center position on both sides of the upper end of the support platform 1 and is connected to a driving hydraulic cylinder 26 via an axis. The output rod end of the driving hydraulic cylinder 26 is connected to a side fixing block 27 via an axis, and the side fixing block 27 is firmly fixed to the upper end of the outer side of the side protective shell 8. When the driving hydraulic cylinder 26 is working, it can smoothly push the outer protective shell 7 to move along the limit sliding groove 4.

[0034] A drive motor 23 is mounted at the lower end of the support platform 1, which drives the third transmission wheel 21 at the front end to rotate via a drive shaft. The second transmission belt 22 synchronously drives the two third transmission wheels 21 to rotate. This is then continuously driven by the second transmission wheel 19 and the first transmission belt 20, ultimately driving the smooth round rod 15 and the bidirectional threaded rod 16 to rotate synchronously. As the bidirectional threaded rod 16 rotates, the sliding block 17 moves toward the center along the smooth round rod 15 and contacts the bidirectional threaded rod 16. Its internal threads 24 tightly mate with the external threads of the threaded rod, driving the two sliding blocks on both sides toward each other, ultimately achieving the slow closing of the outer protective shell 7.

[0035] During the initial movement of the protective structure, the output rod end of the driving hydraulic cylinder 26 extends, pushing the limit sliding block 12 at the lower end of the outer protective shell 7 to slide along the limit sliding groove 4 on the support platform 1. At this time, the driving sliding block 17 moves toward the center along the smooth round rod 15 without affecting the sliding process. In the later stage of the protective structure's movement, the internal threads 24 of the driving sliding block 17 contact the external threads of the bidirectional threaded rod 16. The rotation of the bidirectional threaded rod 16 drives the two driving sliding blocks 17 on each side to move toward the center, and the outer protective shell 7 slowly moves toward the center until it closes.

[0036] Furthermore, after the installation of the protective structure is completed, the thermal insulation cavity 13 inside the inner wall of the side protective shell 8, the upper protective shell 9 and the lower connecting shell 10 of the outer protective shell 7 plays an important role, effectively isolating the external heat, maintaining the stability of the internal temperature of the deaerator, significantly reducing energy loss, and improving the overall economy and environmental protection of the equipment; and avoiding harm to the staff caused by accidental touch.

[0037] Working principle: The drive motor 23 drives the front third transmission wheel 21 to rotate via the transmission shaft. Since the two third transmission wheels 21 are connected via the second transmission belt 22, the two third transmission wheels 21 rotate synchronously in the same direction. The second transmission wheel 19 coaxially connected to the third transmission wheel 21 also rotates synchronously in the same direction. Since the first transmission wheel 18 and the second transmission wheel 19 are connected via the first transmission belt 20, the first transmission wheel 18 rotates synchronously in the same direction, driving the smooth round rod 15 and the bidirectional threaded rod 16 to rotate. The output rod end of the driving hydraulic cylinder 26 extends. Since the two ends of the driving hydraulic cylinder 26 are connected to the shafts of the lower C-shaped fixed seat 25 and the side fixing block 27, respectively, the lower end limit sliding block 12 of the outer protective shell 7 is pushed to slide along the limit sliding groove 4 of the support platform 1, driving the sliding block 17 to move toward the middle direction along the smooth round rod 15.

[0038] When the driving sliding block 17 moves to the outside of the bidirectional threaded rod 16, the internal thread 24 of the driving sliding block 17 contacts the external thread of the bidirectional threaded rod 16. The rotation of the bidirectional threaded rod 16 drives the two driving sliding blocks 17 on each side to move toward the middle, and the outer protective shell 7 moves slowly toward the middle until it closes.

[0039] The outer protective shell 7 provides external protection for the deaerator body 6 to avoid contact with staff. At the same time, the presence of the thermal insulation cavity 13 in the inner wall of the outer protective shell 7 reduces heat exchange with the outside world.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
