Abstract
Description
Technical Field
[0001] This invention belongs to the field of evaporator technology, specifically an evaporator for a small water source heat pump system. Background Technology
[0002] An evaporator is an important piece of equipment that primarily uses heating to vaporize the solvent in a solution, thereby concentrating the solution or precipitating the solute. With increasing environmental protection requirements and the development of industrial technology, evaporator technology is constantly advancing. New evaporator technologies such as low-temperature multi-effect evaporation, high-temperature vapor compression, and low-temperature vacuum evaporation are gradually being applied and promoted.
[0003] When the evaporator is operating, hot water flows through the pipes, and the kinetic and potential energy it carries is easily converted into impact force on the pipes. If the flow rate or pressure spikes abnormally, this force will increase significantly, potentially causing a violent impact on the pipe walls. Over time, this not only accelerates pipe wear but may also lead to rupture risks, seriously affecting equipment safety and operational efficiency. Therefore, ensuring the stability and rationality of hot water flow is crucial, thus requiring modification and optimization. Summary of the Invention
[0004] The purpose of this invention is to provide an evaporator for a small water source heat pump system to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an evaporator for a small water source heat pump system, comprising a shell and copper pipes, wherein the copper pipes are fixedly disposed between two sides inside the shell;
[0006] A damper is fixedly installed between two parts inside the outer shell. A fixed sleeve is fixedly fitted onto the outer surface of the damper. A stainless steel spring is fixedly connected to one end of the fixed sleeve. A movable block is fixedly installed at one end of the stainless steel spring. A hinge block is fixedly installed above the movable block. One end of a connecting rod is hinged inside the hinge block. A hinge block is hinged to the other end of the connecting rod. A base plate is fixedly installed above the hinge block. A connecting plate is movably installed above the base plate.
[0007] Preferably, an L-shaped bracket is fixedly installed on one side of the base plate, and a threaded rod is threadedly sleeved inside the L-shaped bracket. The upper and lower ends of the threaded rod pass through the upper and lower sides of the L-shaped bracket, respectively. The bottom end of the threaded rod passes through the upper and lower sides of the base plate and the connecting plate and is threadedly sleeved on the base plate and the connecting plate. A handle is fixedly installed above the threaded rod.
[0008] Preferably, a connecting copper pipe is fixedly installed at one end of the copper pipe, and one end of the connecting copper pipe penetrates one side of the outer shell. A vertical connecting pipe is fixedly installed above the connecting copper pipe. An arc-shaped sleeve 1 is movably sleeved above the vertical connecting pipe. A fixing plate 3 is fixedly installed at one end of the arc-shaped sleeve 1. A fixing plate 4 is movably installed on one side of the fixing plate 3. An arc-shaped sleeve 2 is fixedly installed on one side of the fixing plate 4. A fixing plate 2 is fixedly installed at one end of the arc-shaped sleeve 2. A fixing plate 1 is fixedly installed at the other end of the arc-shaped sleeve 1. A threaded rod 2 is threadedly sleeved inside the fixing plate 1. One end of the threaded rod 2 penetrates one side of the fixing plate 1 and the upper and lower sides of the fixing plate 2. The other end of the threaded rod 2 penetrates the upper and lower sides of the fixing plate 1 and is fixedly installed with a handle 2.
[0009] Preferably, an expansion valve is movably installed above the vertical connecting pipe, and the bottom end of the expansion valve is movably connected to the arc-shaped sleeve.
[0010] Preferably, there are two connecting plates and two base plates, with one base plate and one connecting plate evenly distributed on one side of the outer shell.
[0011] Preferably, a grid screen is fixedly installed between the two connecting plates, and the grid screen is located on one side of the copper pipe.
[0012] Preferably, the first fixing plate and the second fixing plate are movably connected, and the third fixing plate and the limiting rod are movably connected.
[0013] Preferably, a limiting rod is movably installed inside the fixing plate three, and one end of the limiting rod movably passes through one side of the fixing plate four and is movably connected to the fixing plate four.
[0014] The beneficial effects of this invention are as follows:
[0015] 1. This invention utilizes the impact of hot water flowing through a grid screen to propel the grid screen and subsequent components, including the connecting plate, base plate, and hinge block, backward in sequence. The movement of the hinge block causes one end of the connecting rod to move backward while the other end approaches the fixed sleeve, thereby moving the moving block and hinge block, ultimately compressing the stainless steel spring. Compared to traditional devices, this device avoids damage to the copper pipe caused by the kinetic energy of the water flow by blocking its potential energy, thus reducing the operating cost and improving the working efficiency of the device.
[0016] 2. This invention rotates the handle to drive the threaded rod to rotate. As the threaded rod rotates, it gradually detaches from the base plate and connecting plate. Once the threaded rod is completely detached from the base plate, continue rotating the handle to completely remove the threaded rod from the interior of the connecting plate. At this point, the connecting plate and the grid screen can be disassembled. Compared with traditional devices, this device allows for the replacement of the threaded rod when it is damaged by disassembling the grid screen, instead of directly replacing the copper pipe, thereby reducing the operating cost of the device.
[0017] 3. This invention rotates the second handle to drive the second threaded rod to rotate. Because the first and second fixing plates are threaded together with the second threaded rod, the rotation of the second threaded rod causes the first and second fixing plates to move away from each other, thereby pushing the first and second arc-shaped sleeves to separate and detach from the surface of the vertical connecting pipe. Finally, the vertical connecting pipe is removed from the expansion valve. Compared with traditional devices, this device can reduce the time wasted in installing the expansion valve by quickly fixing and disassembling the vertical connecting pipe and the L-shaped bracket, thus improving the working efficiency of the device.

Detailed Implementation
[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] like Figures 1 to 8 As shown, an embodiment of the present invention provides an evaporator for a small water source heat pump system, including a shell 1 and copper pipes 2, the copper pipes 2 being fixedly disposed between the two sides inside the shell 1;
[0029] A damper 4 is fixedly installed between two parts inside the outer casing 1. A fixed sleeve 5 is fixedly sleeved on the outer surface of the damper 4. A stainless steel spring 6 is fixedly connected to one end of the fixed sleeve 5. A movable block 7 is fixedly installed to one end of the stainless steel spring 6. A hinge block 8 is fixedly installed above the movable block 7. One end of a connecting rod 9 is hinged inside the hinge block 8. A hinge block 10 is hinged to the other end of the connecting rod 9. A base plate 11 is fixedly installed above the hinge block 10. A connecting plate 12 is movably installed above the base plate 11.
[0030] When the staff uses the device, they first place it in a suitable position. The flowing hot water will generate a certain impact force on the screen 24. When the screen 24 is subjected to the impact force, it will move backward. When the screen 24 moves backward, it will cause the connecting plate 12 to move backward. When the connecting plate 12 moves backward, it will drive the base plate 11 to move backward. When the base plate 11 moves backward, it will drive the hinge block 10 to move backward. When the hinge block 10 moves backward, it will cause one end of the connecting rod 9 to move backward, and the other end of the connecting rod 9 will move closer to the fixed sleeve 5, thereby driving the moving block 7 and the hinge block 8 to move, causing the stainless steel spring 6 to be compressed.
[0031] The hot water flow impacts the baffle screen 24, causing the baffle screen 24 and subsequent components such as the connecting plate 12, the base plate 11, and the hinge block 10 to move backward in sequence. The movement of the hinge block 10 causes one end of the connecting rod 9 to move backward, while the other end moves closer to the fixed sleeve 5, thereby driving the moving block 7 and the hinge block 8 to move, ultimately compressing the stainless steel spring 6. Compared with traditional devices, this device avoids damage to the copper pipe 2 by blocking the potential energy of the water flow, thereby reducing the operating cost of the device and improving its working efficiency.
[0032] An L-shaped bracket 13 is fixedly installed on one side of the base plate 11. A threaded rod 14 is threaded inside the L-shaped bracket 13. The upper and lower ends of the threaded rod 14 pass through the upper and lower sides of the L-shaped bracket 13, respectively. The bottom end of the threaded rod 14 passes through the upper and lower sides of the base plate 11 and the connecting plate 12 and is threadedly connected to the base plate 11 and the connecting plate 12. A handle 15 is fixedly installed on the top of the threaded rod 14.
[0033] When the operator uses the device, they first turn handle 15. When handle 15 turns, it drives the threaded rod 14 to rotate. As the threaded rod 14 rotates, because the connection between the connecting plate 12 and the base plate 11 and the threaded rod 14 is threaded, the bottom of the threaded rod 14 will gradually move out of the interior of the base plate 11 as the threaded rod 14 rotates. When the bottom of the threaded rod 14 has completely moved out of the interior of the connecting plate 12, the operator continues to turn handle 15. As the threaded rod 14 continues to rotate, the bottom of the threaded rod 14 will completely move out of the interior of the connecting plate 12. When the bottom of the threaded rod 14 has completely moved out of the interior of the connecting plate 12, the connecting plate 12 and the grid screen 24 can be removed.
[0034] By rotating handle 15, the threaded rod 14 is driven to rotate. As the threaded rod 14 rotates, it gradually separates from the base plate 11 and the connecting plate 12. After the threaded rod 14 is completely separated from the base plate 11, continue to rotate handle 15 to completely remove the threaded rod 14 from the interior of the connecting plate 12. At this time, the connecting plate 12 and the grid screen 24 can be detached. Compared with the traditional device, this device can replace the threaded rod 14 when it is damaged by disassembling the grid screen 24, instead of directly replacing the copper pipe 2, thereby reducing the operating cost of the device.
[0035] Among them, a connecting copper pipe 3 is fixedly installed at one end of the copper pipe 2. One end of the connecting copper pipe 3 passes through one side of the outer shell 1. A vertical connecting pipe 16 is fixedly installed above the connecting copper pipe 3. An arc-shaped sleeve 17 is movably sleeved above the vertical connecting pipe 16. A fixing plate 26 is fixedly installed at one end of the arc-shaped sleeve 17. A fixing plate 27 is movably installed on one side of the fixing plate 26. An arc-shaped sleeve 18 is fixedly installed on one side of the fixing plate 27. A fixing plate 25 is fixedly installed at one end of the arc-shaped sleeve 18. A fixing plate 19 is fixedly installed at the other end of the arc-shaped sleeve 17. A threaded rod 20 is threaded inside the fixing plate 19. One end of the threaded rod 20 passes through one side of the fixing plate 19 and the upper and lower sides of the fixing plate 25. The other end of the threaded rod 20 passes through the upper and lower sides of the fixing plate 19 and is fixedly installed with a handle 21.
[0036] When the operator uses the device, they first turn handle 21. When handle 21 turns, it drives threaded rod 20 to rotate. As threaded rod 20 rotates, the connection between fixed plate 19 and fixed plate 25 and threaded rod 20 is provided with the same thread as threaded rod 20. Therefore, as threaded rod 20 rotates, fixed plate 19 and fixed plate 25 move away from each other, which in turn causes arc sleeve 17 and arc sleeve 28 to move away from each other. When arc sleeve 17 and arc sleeve 28 are separated from the surface of vertical connecting pipe 16, vertical connecting pipe 16 can be removed from the inside of expansion valve 23.
[0037] By rotating the handle 21, the threaded rod 20 is rotated. Since there are threads between the fixing plate 19, the fixing plate 25 and the threaded rod 20, the rotation of the threaded rod 20 causes the fixing plate 19 and the fixing plate 25 to move away from each other, thereby pushing the arc sleeve 17 and the arc sleeve 28 to separate and detach from the surface of the vertical connecting pipe 16. Finally, the vertical connecting pipe 16 is removed from the expansion valve 23. Compared with the traditional device, this device can reduce the time wasted in installing the expansion valve 23 by quickly fixing and disassembling the vertical connecting pipe 16 and the L-shaped bracket 13, thereby improving the working efficiency of the device.
[0038] An expansion valve 23 is movably installed above the vertical connecting pipe 16, and the bottom end of the expansion valve 23 is movably connected to the arc-shaped sleeve 17.
[0039] The expansion valve 23 allows for the recycling of condensate, improving its efficiency and reducing operating costs.
[0040] There are two connecting plates 12 and two base plates 11, which are evenly distributed on one side of the outer shell 1, with one base plate 11 and one connecting plate 12 forming a group.
[0041] The design of the connecting plate 12 facilitates the fixing of the position of the grid screen 24, thereby improving the stability of the grid screen 24 during use.
[0042] A grid screen 24 is fixedly installed between the two connecting plates 12, and the grid screen 24 is located on one side of the copper pipe 2.
[0043] The design of the baffle screen 24 can block the impact force generated by hot water, preventing the impact force generated by hot water from directly contacting the copper pipe 2 and causing damage to the copper pipe 2.
[0044] Among them, fixing plate 19 and fixing plate 25 are movably connected, and fixing plate 3 and limiting rod 22 are movably connected.
[0045] The movable connection between the fixing plate 19 and the handle 15 allows the arc sleeve 17 and the arc sleeve 2 18 to be quickly removed from the outer surface of the vertical connecting tube 16.
[0046] Among them, a limiting rod 22 is movably installed inside the fixed plate 3 26, and one end of the limiting rod 22 movably passes through one side of the fixed plate 4 27 and is movably connected to the fixed plate 4 27.
[0047] The design of the limiting rod 22 facilitates the movement of the arc sleeve 17 and the arc sleeve 2 18, thereby improving the working efficiency of the device.
[0048] Working principle and usage process:
[0049] When the staff uses the device, they first place it in a suitable position. The flowing hot water will generate a certain impact force on the screen 24. When the screen 24 is subjected to the impact force, it will move backward. When the screen 24 moves backward, it will cause the connecting plate 12 to move backward. When the connecting plate 12 moves backward, it will drive the base plate 11 to move backward. When the base plate 11 moves backward, it will drive the hinge block 10 to move backward. When the hinge block 10 moves backward, it will cause one end of the connecting rod 9 to move backward, and the other end of the connecting rod 9 will move closer to the fixed sleeve 5, thereby driving the moving block 7 and the hinge block 8 to move, causing the stainless steel spring 6 to be compressed.
[0050] When the operator uses the device, they first turn handle 15. When handle 15 turns, it drives the threaded rod 14 to rotate. As the threaded rod 14 rotates, because the connection between the connecting plate 12 and the base plate 11 and the threaded rod 14 is threaded, the bottom of the threaded rod 14 will gradually move out of the interior of the base plate 11 as the threaded rod 14 rotates. When the bottom of the threaded rod 14 has completely moved out of the interior of the connecting plate 12, the operator continues to turn handle 15. As the threaded rod 14 continues to rotate, the bottom of the threaded rod 14 will completely move out of the interior of the connecting plate 12. When the bottom of the threaded rod 14 has completely moved out of the interior of the connecting plate 12, the connecting plate 12 and the grid screen 24 can be removed.
[0051] When the operator uses the device, they first turn handle 21. When handle 21 turns, it drives threaded rod 20 to rotate. As threaded rod 20 rotates, the connection between fixed plate 19 and fixed plate 25 and threaded rod 20 is provided with the same thread as threaded rod 20. Therefore, as threaded rod 20 rotates, fixed plate 19 and fixed plate 25 move away from each other, which in turn causes arc sleeve 17 and arc sleeve 28 to move away from each other. When arc sleeve 17 and arc sleeve 28 are separated from the surface of vertical connecting pipe 16, vertical connecting pipe 16 can be removed from the inside of expansion valve 23.
