Description

Technical Field

[0001] This utility model relates to the field of condensate recovery technology, specifically to a condensate recovery coil for a single-effect concentrator. Background Technology

[0002] In the pharmaceutical, food, and chemical industries, single-effect concentrators are widely used in the concentration process of materials. During this process, a large amount of high-temperature condensate is generated. Direct discharge of this condensate not only wastes water resources but also leads to heat loss. Therefore, the recycling of condensate has become an important aspect of energy conservation and consumption reduction.

[0003] Traditional condensate recovery systems often use flange connections to connect the recovery coil to the concentrator. However, flange connections have problems such as insufficient sealing performance, cumbersome installation and disassembly, and easy condensate leakage, which not only affect the recovery efficiency but may also cause equipment corrosion and environmental pollution. Utility Model Content

[0004] The purpose of this invention is to provide a condensate recovery coil for a single-effect concentrator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-effect concentrator condensate recovery coil, comprising a pipe body, with a water outlet fixedly connected to the bottom end of the pipe body, and a connecting mechanism installed at the top end of the pipe body. The connecting mechanism includes a sleeve, a sealing ring, and a sealing head. The sealing ring is installed inside the sleeve, and the sealing head is threadedly connected to the inner wall of the sleeve. A fixing block is fixedly connected to the top of the sealing head, and a conveying pipe is fixedly connected inside the fixing block. A sealing plate is installed above the sealing ring.

[0006] As a preferred technical solution of this utility model, the bottom of the sealing head is provided with an annular sealing groove, and the sealing head and the sealing groove are connected.

[0007] As a preferred technical solution of this utility model, the sealing groove and the sealing plate are adapted to each other, the sealing plate is slidably connected inside the sealing groove, and the center point of the sealing groove and the center point of the sealing plate are on the same vertical line.

[0008] As a preferred embodiment of this utility model, the bottom of the fixing block abuts against the top edge of the sleeve, the inner diameter of the fixing block is equal to the inner diameter of the tube body, and the outer diameter of the fixing block is equal to the outer diameter of the sleeve.

[0009] In a preferred embodiment of this invention, the thickness of the sealing plate is greater than the thickness of the sealing groove, and the outer diameter of the sealing plate is smaller than the inner diameter of the sleeve.

[0010] As a preferred embodiment of this utility model, the sealing plate is fixedly connected to the top end of the pipe body, and the sleeve is slidably fitted onto the outside of the pipe body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By optimizing the structural design of the connection mechanism and adopting a multi-seal method with threaded tightening, the sealing performance and ease of operation at the connection between the coil and the concentrator are significantly improved. Specifically, the sealing head and the sleeve are connected by threads. During the tightening process, the sealing plate first enters the sealing groove to achieve a preliminary seal. As it is further tightened, the fixing block fits tightly against the top edge of the sleeve, and at the same time, a pressure seal is formed between the sealing plate and the sealing ring, effectively preventing condensate leakage. This structure not only provides a reliable seal and avoids the problems of easy leakage and complicated installation of traditional flange connections, but also facilitates disassembly and maintenance, improving the efficiency and safety of condensate recovery. It is suitable for high-temperature condensate recovery scenarios in industries such as pharmaceuticals, food, and chemicals, and has significant energy-saving, consumption-reducing, and environmental benefits.

[0014] 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.

[0015] Please see Figures 1 to 3This utility model provides a condensate recovery coil for a single-effect concentrator, including a pipe body 1. The bottom end of the pipe body 1 is fixedly connected to a water outlet 2, and the top end of the pipe body 1 is equipped with a connecting mechanism 3. The connecting mechanism 3 includes a sleeve 31, a sealing ring 32, and a sealing head 33. The sealing ring 32 is installed inside the sleeve 31, and the sealing head 33 is threadedly connected to the inner wall of the sleeve 31. The top of the sealing head 33 is fixedly connected to a fixing block 34, and the inside of the fixing block 34 is fixedly connected to a conveying pipe 35. A sealing plate 36 is installed above the sealing ring 32.

[0016] Furthermore, an annular sealing groove 37 is provided at the bottom of the sealing head 33. The sealing head 33 and the sealing groove 37 are connected. Its function is to provide a precise annular channel for the insertion and guidance of the sealing plate 36, ensuring that the sealing plate 36 can smoothly and centrally enter the sealing groove 37 during the process of the sealing head 33 screwing into the sleeve 31. This lays the foundation for forming an effective primary seal, ensures the coaxiality and smoothness of the sealing process, and avoids sealing failure caused by misalignment.

[0017] Furthermore, the sealing groove 37 and the sealing plate 36 are adapted to each other, and the sealing plate 36 is slidably connected inside the sealing groove 37. The center point of the sealing groove 37 and the center point of the sealing plate 36 are on the same vertical line. Its function is to enable the sealing plate 36 to slide tightly into the sealing groove 37 and fill its space through precise dimensional fit and centering design, so as to achieve preliminary radial sealing and reduce the possibility of condensate leakage from the connection gap.

[0018] Furthermore, the bottom of the fixing block 34 abuts against the top edge of the sleeve 31. The inner diameter of the fixing block 34 is equal to the inner diameter of the pipe body 1, and the outer diameter of the fixing block 34 is equal to the outer diameter of the sleeve 31. When the sealing head 33 is fully tightened, the fixing block 34 and the top of the sleeve 31 form end face contact and limit, while keeping the inner diameter of the flow channel consistent to avoid fluid disturbance and pressure loss. The effect is to achieve both a stable connection and axial positioning of the structure, and to ensure smooth flow of fluid, thereby improving the overall stability and transmission efficiency of the system.

[0019] Furthermore, the thickness of the sealing plate 36 is greater than the thickness of the sealing groove 37, and the outer diameter of the sealing plate 36 is smaller than the inner diameter of the sleeve 31. When the fixing block 34 abuts against the top of the sleeve 31, the sealing plate 36 can maintain a certain amount of compression in the sealing groove 37 and generate a pressing force with the sealing ring 32 above, forming a reliable and self-tightening axial end face seal, which doubles the sealing performance of the connection and effectively prevents the leakage of high temperature and high pressure condensate.

[0020] Furthermore, the sealing plate 36 is fixedly connected to the top end of the pipe body 1, and the sleeve 31 is slidably sleeved on the outside of the pipe body 1, so that the sleeve 31 can move axially and adjust the angle relative to the pipe body 1, thereby facilitating docking with the sealing head 33. The effect is to significantly simplify the installation and disassembly process, improve the convenience of assembly and work efficiency, and facilitate later maintenance and replacement.

[0021] Working principle: First, connect the delivery pipe 35 to the condensate outlet of the single-effect concentrator. By rotating the sleeve 31, it begins to screw into the sleeve 31 via threads. During this process, the annular sealing groove 37 at the bottom of the sealing head 33 gradually approaches and fits into the sealing plate 36 fixed at the top of the pipe body 1. Because the sealing groove 37 and the sealing plate 36 are precisely matched and centered, the sealing plate 36 can smoothly slide into the interior of the sealing groove 37, forming the first radial seal, effectively preventing initial leakage of condensate. As the sleeve 31 continues to tighten, the bottom of the fixing block 34 finally abuts and presses against the top edge of the sleeve 31, achieving axial limiting and end face sealing. At the same time, because the thickness of the sealing plate 36 is designed to be greater than that of the sealing head 33, the sealing plate 34 can be screwed into the sleeve 31. When the sealing groove 37 is tightened to the correct position, the sealing plate 36 is compressed within the sealing groove 37, further pressing the sealing ring 32, thus forming a second tight axial end face seal. This dual sealing mechanism works together to ensure the sealing reliability of the connection under high temperature and high pressure conditions. After the condensate flows out from the single-effect concentrator, it enters the interior of the pipe body 1 through the delivery pipe 35 and the fixing block 34. Since the fixing block 34 has the same inner diameter as the pipe body 1, the flow path is smooth and without abrupt changes. The condensate can flow steadily to the outlet 2 at the bottom of the pipe body 1 and be collected and recycled. When disassembly is required, the sleeve 31 only needs to be rotated in the opposite direction to gradually release the pressing state of each sealing surface, achieving quick and convenient separation and greatly simplifying the maintenance process.
