Description
Technical Field
[0001] This utility model relates to the technical field of protection and warmth preservation, and in particular to a winter antifreeze device for desalination stations. Background Technology
[0002] Demineralization plants are used in industries such as power and chemicals to produce high-purity water. Their core equipment (such as reverse osmosis membranes and pipelines) is prone to freezing and cracking or performance failure in low-temperature environments. Traditional anti-freezing measures mainly include: 1. Electric heat tracing: wrapping electric heating tape around the pipeline to maintain temperature through resistance heating. However, this method is energy-intensive (requires continuous power supply), has uneven coverage (difficult to fully cover large equipment), and poses a risk of electric leakage. 2. Steam heat tracing: laying steam pipes along the equipment to utilize waste steam heat for insulation. Disadvantages include low thermal efficiency (steam condensate needs to be recovered), complex system, and unsuitability for small stations without a steam source. 3. Building insulated sheds: constructing temporary insulated sheds to enclose the equipment, using warm air blowers for internal heating. Although lower in cost, it lacks flexibility (cannot adapt to irregularly shaped equipment), occupies a large space, and the warm air blowers pose a risk of drying out. Traditional anti-freezing measures have the following shortcomings: First, insufficient adaptability: the structure of the device cannot be flexibly adjusted according to the height and specifications of the demineralization plant, resulting in unstable anti-freezing effects. Secondly, the heat circulation effect is poor: electric heat tracing or fixed hot water circulation systems consume a lot of energy, and the entire structure needs to be disassembled for maintenance, resulting in low maintenance efficiency. Thirdly, the space utilization rate is low and the maintenance is poor: traditional devices are mostly fixed and cannot be stored when not in use, occupying space resources, which is particularly prominent in compact industrial settings, and maintenance is also difficult. Utility Model Content
[0003] The purpose of this utility model is to provide a winter antifreeze device for demineralized water stations, which addresses the shortcomings of existing technologies such as insufficient adaptability, poor thermal circulation effect, low space utilization, and poor maintenance.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a winter antifreeze device for a desalination station, comprising two sets of telescopic pipe devices symmetrically arranged on the left and right, a flipping device and a lifting device disposed at the bottom of the telescopic pipe devices, characterized in that the telescopic pipe devices include water pipe A, water pipe B and water pipe C; water pipe B is installed inside water pipe A, and the two form an up-and-down sliding structure; water pipe C is installed inside water pipe B, and the two form an up-and-down sliding structure; each set of telescopic pipe devices has two sets of lifting devices symmetrically arranged at the top of water pipe B and water pipe C.
[0005] Preferably, the two sets of telescopic pipe devices are fixed in an upper and lower structure and connected by two horizontal water pipes. The lower horizontal water pipe is connected to two water pipes A on the left and right sides, and the upper horizontal water pipe is connected to two water pipes C on the left and right sides. The two horizontal water pipes are fixed vertically and connected by several vertical water pipes.
[0006] Preferably, the top of the water pipe A is provided with a retaining ring A, the inner diameter of which matches the outer diameter of the water pipe B; the bottom of the water pipe B is provided with a retaining ring B, the outer diameter of which matches the inner diameter of the water pipe A.
[0007] Preferably, the top of water pipe B is provided with a retaining ring D, the inner diameter of which matches the outer diameter of water pipe C; the bottom of water pipe C is provided with a retaining ring C, the outer diameter of which matches the inner diameter of water pipe B.
[0008] Preferably, the lifting device includes a rotary motor, a lead screw, and a connecting block. A connecting block is fitted at the center of the top of both water pipe B and water pipe C. Each connecting block has two threaded through holes symmetrically arranged at both ends. A matching lead screw is connected to each threaded through hole, and a rotary motor is connected to the bottom of each lead screw.
[0009] Preferably, the flipping device includes a U-shaped block, a rotating block, a support base, a U-shaped pull block, and a hydraulic cylinder; the top of the U-shaped block has a through hole, inside which a rotating shaft is fixed, and the bottom has a horizontal key-shaped through hole; the rotating block is located inside the U-shaped block, with a through hole at the top that is rotatably connected to the rotating shaft of the U-shaped block, and a vertical key-shaped through hole at the bottom that is the same as the horizontal key-shaped through hole on the U-shaped block; the support base is fixed to the top of the rotating block.
[0010] Preferably, the inner width of the U-shaped pull block matches the outer width of the U-shaped block, one end of the U-shaped pull block is provided with a rotating shaft with two key-shaped through holes that match, the rotating shaft is inserted into the two key-shaped through holes at the same time, and the other end of the U-shaped pull block is connected to the output rod of the hydraulic cylinder.
[0011] Preferably, the two rotary motors of the two lifting devices of water pipe B are fixed on the upper surface of the support base; the two rotary motors of the two lifting devices of water pipe C are fixed on the upper surface of the connecting block of water pipe B.
[0012] Compared with the prior art, the present invention has the following beneficial effects.
[0013] 1. The telescopic pipe device consists of water pipes A, B, and C. The screw is driven by the rotating motor of the lifting device to allow water pipe B to slide up and down inside water pipe A and water pipe C to slide up and down inside water pipe B. This allows the total height of the device to be flexibly adjusted to adapt to demineralized water stations of different heights without the need for customized production, making it highly versatile.
[0014] 2. The flipping device uses a hydraulic cylinder to pull a U-shaped block, causing the rotating block to rotate 90° around the axis, so that the device changes from a vertical position to a horizontal position on the ground. When not in use, it can be stored close to the wall, saving space. When inspecting the demineralized water station, there is no need to disassemble the pipeline; simply flipping the device will expose the equipment, improving maintenance efficiency.
[0015] 3. The horizontal and vertical water pipes are connected to form a cage-like heat dissipation structure. Hot water flows in from the joint and is evenly distributed, and is protected by heat dissipation through the metal pipe wall. The design of the retaining rings A, B, C, and D ensures that there are no gaps at the water pipe connection, preventing hot water leakage, and at the same time limits the sliding range of the water pipe to prevent it from coming off.
[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figure 1-8 A winter antifreeze device for a demineralized water station includes two sets of telescopic pipe devices 11 arranged symmetrically on the left and right, a flipping device 7 and a lifting device 8 located at the bottom of the telescopic pipe devices 11. The telescopic pipe device 11 comprises a water pipe A 1, a water pipe B 2, and a water pipe C 3; water pipe B 2 is fitted inside water pipe A 1, and the two form a sliding structure; water pipe C 3 is fitted inside water pipe B 2, and the two form a sliding structure; each set of telescopic pipe devices 11 has two sets of lifting devices 8 symmetrically arranged at the top of water pipe B 2 and water pipe C 3. Water pipe B 2 slides up and down inside water pipe A 1, and water pipe C 3 slides up and down inside water pipe B 2. The two sets of sliding devices work together to change the total height of the telescopic pipe device 11, adapting to demineralized water stations of different heights available on the market.
[0028] The two sets of telescopic pipe devices 11 are fixed vertically and connected by two horizontal water pipes 4. The lower horizontal water pipe 4 connects to two water pipes A1 on the left and right sides, and the upper horizontal water pipe 4 connects to two water pipes C3 on the left and right sides. The two horizontal water pipes 4 are vertically fixed and connected by several vertical water pipes 5. A connector 6 is provided on the water pipe A1. In use, several of these devices are evenly arranged in the length and width directions according to the length and width of the demineralized water station 9, forming a steamer-like structure that surrounds the demineralized water station 9. One of the connectors 6 is connected to a hot water supply device via a flexible hose. Hot water enters the telescopic pipe device 11 from the connector 6 and flows into each horizontal water pipe 4 and vertical water pipe 5. The hot water inside dissipates heat, raising the temperature of the demineralized water station 9 in the middle, preventing the demineralized water station 9, especially the reverse osmosis membrane inside, from freezing. Then it flows out from the connector 6 of another water pipe A1, forming a complete circulation pipeline.
[0029] The top of water pipe A1 is equipped with a retaining ring A101, the inner diameter of which matches the outer diameter of water pipe B2; the bottom of water pipe B2 is equipped with a retaining ring B201, the outer diameter of which matches the inner diameter of water pipe A1. The top of water pipe B2 is equipped with a retaining ring D202, the inner diameter of which matches the outer diameter of water pipe C3; the bottom of water pipe C3 is equipped with a retaining ring C301, the outer diameter of which matches the inner diameter of water pipe B2. The design of these retaining rings serves two purposes: first, to ensure seamless connection between water pipe A1 and water pipe B2, and between water pipe B2 and water pipe C3, preventing leakage; and second, to act as a limit, preventing water pipe B2 from detaching from water pipe A1, and water pipe C3 from detaching from water pipe B2, during vertical sliding.
[0030] The lifting device 8 includes a rotary motor 801, a lead screw 802, and a connecting block 803. A connecting block 803 is centrally fitted onto the top of each of the water pipes B2 and C3. Each connecting block has two symmetrically arranged threaded holes at both ends, and a matching lead screw 802 is connected to each threaded hole. A rotary motor 801 is connected to the bottom of each lead screw. The rotary motor 801 rotates forward and backward, driving the lead screw to rotate forward and backward, causing the connecting block 803 to rise or fall. Because the connecting block 803 is fixed to the top of water pipe B2 or water pipe C3, the rise and fall of water pipe B2 or water pipe C3 achieves the effect of adjusting the height of the telescopic pipe device 11. The lead screw thread has good self-locking properties, and the height will not easily change after adjustment. The connecting block 803 has a positioning and limiting structure to prevent water pipe B2 or water pipe C3 from rotating during lifting.
[0031] The flipping device 7 includes a U-shaped block 701, a rotating block 702, a support base 703, a U-shaped pull block 704, and a hydraulic cylinder 705. The U-shaped block 701 has a through hole at its top, inside which a rotating shaft is fixed, and a keyed through hole horizontally at its bottom. The rotating block 702 is located inside the U-shaped block 701, with a through hole at its top that is rotatably connected to the rotating shaft of the U-shaped block 701, and a keyed through hole vertically at its bottom that is identical to the horizontal keyed through hole on the U-shaped block 701. The support base 703 is fixed to the top of the rotating block 702. The internal width of the U-shaped pull block 704 matches the external width of the U-shaped block 701. One end of the U-shaped pull block 704 has a rotating shaft with two matching keyed through holes, which is simultaneously inserted into both keyed through holes. The other end of the U-shaped pull block 704 is connected to the output rod of the hydraulic cylinder 705. Hydraulic cylinder 705 pulls U-shaped pull block 704 backward. The pivot of U-shaped pull block 704 slides backward in the horizontal keyed through hole of U-shaped block 701. Because the pivot of U-shaped pull block 704 is simultaneously in the vertical keyed through hole of rotating block 702, rotating block 702 rotates. When the pivot of U-shaped pull block 704 reaches the rear end of the horizontal keyed through hole of U-shaped block 701, rotating block 702 completes a 90° rotation, causing a change in the structure on support base 703. This changes the device from being perpendicular to the ground to being placed on the ground, saving space. It can be used for maintenance of demineralized water station 9 or for storage when not in use for a short period of time. Figure 8 As shown.
[0032] The two rotating motors 801 of the two lifting devices 8 of water pipe B2 are fixed to the upper surface of the support base 703; the two rotating motors 801 of the two lifting devices 8 of water pipe C3 are fixed to the upper surface of the connecting block 803 of water pipe B2. The structure is more compact and saves space.
[0033] Working process: After connecting all components or structures of this utility model, ensure sealing. Place the two sets of telescopic pipe devices 11 symmetrically around the demineralized water station 9, and fix them to the ground or foundation support through the support base 703 of the flipping device 7, ensuring that the U-shaped block 701 and the rotating block 702 are firmly connected. Start the rotary motor 801 between water pipe A 1 and water pipe B 2. The motor rotates clockwise, driving the lead screw 802 to rotate clockwise. The connecting block 803 moves upward along the lead screw, pushing water pipe B 2 to rise inside water pipe A 1. Similarly, start the rotary motor 801 between water pipe B 2 and water pipe C 3, driving water pipe C 3 to rise inside water pipe B 2, until the total height of the telescopic pipe device 11 matches that of the demineralized water station 9. A horizontal water pipe 4 connects water pipes A1 (lower horizontal water pipe) and C3 (upper horizontal water pipe) on both sides, and a vertical water pipe 5 is installed between the horizontal water pipes 4, forming a cage-like enclosure structure. A connector 6 on one of the water pipes A1 is connected to an external hot water source (such as a boiler or electric water heater) via a flexible hose. When the hot water source is turned on, hot water flows in through connector 6 and circulates through various pipes. During this flow, the hot water dissipates heat through the metal pipe walls, raising the temperature around the demineralized water station and preventing the equipment from freezing. The hot water then flows out from connector 6 of the other water pipe A1, forming a complete circulation pipeline.
[0034] When the demineralized water station needs maintenance, start the hydraulic cylinder 705. Its output rod pulls the U-shaped block 704 backward. The rotating shaft of the U-shaped block 704 slides in the horizontal keyed through hole of the U-shaped block 701, simultaneously driving the vertical keyed through hole of the rotating block 702 to rotate. When the rotating shaft reaches the end of the horizontal keyed through hole, the rotating block completes a 90° rotation, and the support base 703 and the telescopic pipe device 11 above it tilt to a horizontal position, exposing the demineralized water station 9 equipment. After maintenance or during short-term idle periods, keep the equipment horizontal. Multiple units can be stored side by side against a corner of the wall or covered with a dust cover to reduce space occupation. When using it again, reverse the operation of the hydraulic cylinder to restore the equipment to a vertical position and readjust the height.
