Description

Technical Field

[0001] This utility model relates to the technical field of secondary circulating water purification in heat exchange stations of thermal systems, and in particular to a purification and upgrading device for secondary circulating water in heat exchange stations of thermal systems. Background Technology

[0002] In existing technologies, water-based intelligent cleaning equipment is used to clean scale in the secondary circulating water of a heat exchange station in a thermal system. This equipment mainly consists of a main body and end caps. It utilizes the electrochemical properties of anions and cations in water to solve the scaling problem in the circulating water system. This is achieved by passing direct current between the anode and cathode plates, forming a large amount of scale in the strongly alkaline environment of the cathode region through electro-adsorption. The equipment also controls the Langerile index (LSI) and stability index of the water to regulate the salt balance, thereby controlling scaling and corrosion. Compared to traditional industrial water purification equipment, the main body of the water-based intelligent cleaning equipment is cylindrical due to the higher water pressure in the secondary circulating water of the heat exchange station. This results in more uniform pressure distribution and thicker walls, enhancing its pressure resistance.

[0003] During use, because the secondary circulating water of the heat exchange station of the thermal system has strict control over water loss, the water-cleaning equipment needs to be opened every two months to clean the scale. However, due to the large weight of the end cap, it is time-consuming, laborious and unsafe to open it manually. Utility Model Content

[0004] In order to improve the efficiency of scale removal and reduce safety hazards, this application provides a purification and upgrading device for the secondary circulating water of a heat exchange station in a thermal system.

[0005] This application provides a secondary circulating water purification and enhancement device for a heat exchange station in a thermal system, which adopts the following technical solution:

[0006] A purification and lifting device for secondary circulating water in a heat exchange station of a thermal system includes a main body, an end cover installed at the top of the main body, a lifting mechanism installed on the main body, and an auxiliary mechanism installed on the end cover. The lifting mechanism includes a hook and a power component, and the hook is slidably connected to the main body through the power component.

[0007] By adopting the above technical solution, when opening and transferring the end cap, the hook is manually hung on the auxiliary mechanism, and then the power unit is started. The power unit drives the hook to rise, and the hook drives the end cap to rise through the auxiliary mechanism, thereby realizing the transfer of the end cap, improving the transfer efficiency and reducing the safety hazards during manual transfer.

[0008] Optionally, the main body is further equipped with a rotating mechanism. The power assembly includes a rotating rod, which is rotatably connected to the main body via the rotating mechanism. A mounting plate is fixedly connected to the rotating rod. A first motor is fixedly connected to the end face of the mounting plate away from the main body. A winch is also rotatably connected to the end face of the mounting plate away from the main body. The output shaft of the first motor is fixedly connected to the winch. A connecting rope is wound on the winch. One end of the connecting rope is fixedly connected to the winch, and the end of the connecting rope away from the winch is fixedly connected to the hook.

[0009] By adopting the above technical solution, when the end cap is lifted, the first motor starts, drives the winch to rotate, the winch drives the connecting rope to wind, the connecting rope drives the hook to rise, and the hook drives the end cap to rise through the auxiliary mechanism; thus, the lifting of the end cap is more stable and more efficient.

[0010] Optionally, the lifting mechanism further includes a reinforcing rod, which is fixedly connected to the rotating rod, and the end of the reinforcing rod away from the rotating rod is fixedly connected to the mounting plate.

[0011] By adopting the above technical solution, since the end cap is relatively heavy, the mounting plate is also subjected to a large tensile force, which can easily lead to breakage at the connection between the rotating rod and the mounting plate. The setting of the reinforcing rod creates a triangular structure between the rotating rod, the reinforcing rod and the mounting plate, which makes the mounting plate more secure.

[0012] Optionally, the auxiliary mechanism includes two lifting noses, each with a fixed rope, and a lifting ring fixedly connected to one end of each fixed rope away from the lifting nose. The lifting ring engages with the lifting hook.

[0013] By adopting the above technical solution, when the end cap is lifted and installed, the hook is manually attached to the lifting ring. At the same time, the setting of two fixing ropes makes the end cap more balanced during lifting, making the lifting and lowering of the end cap more stable.

[0014] Optionally, the rotating mechanism includes a sleeve, which is fixedly connected to the side wall of the main body. The rotating rod is rotatably connected in the sleeve. A limiting groove is formed on the end face of the sleeve. A rotating groove is formed on the side wall of the limiting groove. A limiting block is fixedly connected to the side wall of the rotating rod. The limiting block passes through the limiting groove and is rotatably connected in the rotating groove.

[0015] By adopting the above technical solution, when the end cap is lifted, it is still above the main body. When the operator cleans the scale inside the main body, the operator is also above the main body. Therefore, there is still a probability that the end cap may fall and cause injury to the operator. However, the sleeve and limit block enable the rotation of the rotating rod, which in turn enables the rotation of the end cap. By rotating the rotating rod, the end cap is rotated out of the main body, thereby reducing the probability that the end cap may accidentally fall and cause injury to the operator.

[0016] Optionally, the rotating mechanism further includes a drive assembly, which includes a second motor that is connected to the main body. A first bevel gear is keyed to the output shaft of the second motor, and a second bevel gear is fixedly connected to the end of the rotating rod away from the mounting plate. The first bevel gear meshes with the second bevel gear.

[0017] By adopting the above technical solution, when the end cover is rotated, the second motor starts, the second motor drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the rotating rod to rotate, and thus drives the end cover to rotate.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. When opening and transferring the end cap, manually hook the hook onto the auxiliary mechanism, then start the power unit. The power unit drives the hook to rise, and the hook drives the end cap to rise through the auxiliary mechanism, thereby realizing the transfer of the end cap, improving the transfer efficiency and reducing the safety hazards during manual transfer;

[0020] 2. Because the end cap is relatively heavy, the mounting plate is also subjected to a large tensile force, which can easily lead to breakage at the connection between the rotating rod and the mounting plate; the reinforcing rod creates a triangular structure between the rotating rod, the reinforcing rod and the mounting plate, thus making the mounting plate more secure.

[0021] 3. When lifting and installing the end cap, manually hook the hook onto the lifting ring. The two fixing ropes make the end cap more balanced during lifting, making the lifting and lowering of the end cap more stable.

[0022] 4. When the end cap is lifted, it is still above the main body. When the operator cleans the scale inside the main body, the operator is also above the main body. Therefore, there is still a probability that the end cap may fall and injure the operator. The sleeve and limit block are designed to rotate the rotating rod, which in turn allows the end cap to rotate. By rotating the rotating rod, the end cap is rotated out of the main body, thus reducing the probability of the end cap accidentally falling and injuring the operator. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] This application discloses a device for purifying and upgrading the secondary circulating water of a heat exchange station in a thermal system.

[0031] refer to Figure 1 The heat exchange station secondary network circulating water purification and lifting device of the heat system includes a main body 1, which is installed on the ground. An end cover 2 is installed on the top of the main body 1. A rotating mechanism 5 is also installed on the main body 1. A lifting mechanism 3 is installed on the rotating mechanism 5. An auxiliary mechanism 4 that cooperates with the lifting mechanism 3 is installed on the end cover 2.

[0032] When the end cap 2 is opened and transferred, the end cap 2 is first fixed to the lifting mechanism 3 by the auxiliary mechanism 4. Then the lifting mechanism 3 lifts the end cap 2 away from the main body 1. Then the rotating mechanism 5 drives the end cap 2 to rotate out of the top of the main body 1, thereby realizing the transfer of the end cap 2, improving the transfer efficiency and reducing the safety hazards during manual transfer.

[0033] refer to Figure 2The lifting mechanism 3 includes a power component 32, which includes a rotating rod 321. The rotating rod 321 is rotatably connected to the main body 1 via a rotating mechanism 5. A mounting plate 322 is fixedly connected to the end of the rotating rod 321 away from the ground. A first motor 323 is fixedly connected to the end face of the mounting plate 322 away from the main body 1. A winch 324 is also rotatably connected to the end face of the mounting plate 322 away from the main body 1. The output shaft of the first motor 323 is fixedly connected to the winch 324. A connecting rope 325 is also rotatably connected to the winch 324. One end of the connecting rope 325 is fixedly connected to the winch 324, and the other end of the connecting rope 325 is fixedly connected to a hook 31.

[0034] When the end cover 2 is lifted, the first motor 323 starts, the first motor 323 drives the winch 324 to rotate, the winch 324 drives the connecting rope 325 to wind, the connecting rope 325 drives the hook 31 to rise, and the hook 31 drives the end cover 2 to rise through the auxiliary mechanism 4; thus making the lifting of the end cover 2 more stable and more efficient.

[0035] The lifting mechanism 3 also includes multiple reinforcing rods 33, which are all fixedly connected to the side wall of the rotating rod 321 and located at the end of the rotating rod 321 near the mounting plate 322. The end of the reinforcing rod 33 away from the rotating rod 321 is fixedly connected to the mounting plate 322. Since the end cap 2 is relatively heavy, the mounting plate 322 is also subjected to a large tensile force, which can easily cause breakage at the connection between the rotating rod 321 and the mounting plate 322. The setting of the reinforcing rods 33 forms a triangular structure between the rotating rod 321, the reinforcing rods 33 and the mounting plate 322, which makes the mounting plate 322 more firmly fixed.

[0036] refer to Figure 3 The auxiliary mechanism 4 includes two lifting noses 41, with fixed ropes 42 fixedly connected to the two lifting noses 41. The ends of the two fixed ropes 42 away from the lifting noses 41 are fixedly connected to a lifting ring 43, which cooperates with the hook 31. When the end cap 2 is lifted and installed, the hook 31 is manually hooked onto the lifting ring 43. At the same time, the setting of the two fixed ropes 42 makes the end cap 2 more balanced during lifting, making the lifting and lowering of the end cap 2 more stable.

[0037] refer to Figure 4 and Figure 5 The rotating mechanism 5 includes a sleeve 51, which is fixedly connected to the side wall of the main body 1. The rotating rod 321 is rotatably connected in the sleeve 51. A limiting groove 511 is opened on the end face of the sleeve 51 away from the ground. A rotating groove 512 is opened on the bottom wall of the limiting groove 511. A limiting block 52 is fixedly connected to the side wall of the rotating rod 321. The limiting block 52 passes through the limiting groove 511 and is rotatably connected in the rotating groove 512.

[0038] When the end cap 2 is lifted, it is still above the main body 1. When the operator cleans the scale inside the main body 1, the operator is also above the main body 1. Therefore, there is still a probability that the end cap 2 may fall and injure the operator. The sleeve 51 and the limiting block 52 enable the rotation of the rotating rod 321, which in turn enables the rotation of the end cap 2. By rotating the rotating rod 321, the end cap 2 is rotated out of the main body 1, thereby reducing the probability that the end cap 2 may accidentally fall and injure the operator.

[0039] The rotating mechanism 5 also includes a drive assembly 53, which includes a second motor 531. The second motor 531 is fixedly connected to the side wall of the main body 1. A first bevel gear 532 is keyed to the output shaft of the second motor 531. A second bevel gear 533 is fixedly connected to the end of the rotating rod 321 away from the mounting plate 322. The first bevel gear 532 and the second bevel gear 533 mesh. When the end cover 2 is rotated, the second motor 531 is started, and the second motor 531 drives the first bevel gear 532 to rotate. The first bevel gear 532 drives the second bevel gear 533 to rotate, and the second bevel gear 533 drives the rotating rod 321 to rotate, thereby driving the end cover 2 to rotate.

[0040] The implementation principle of the secondary circulating water purification and lifting device of the heat exchange station of the thermal system in this application embodiment is as follows: When the end cover 2 is opened and transferred, the hook 31 is manually hung on the lifting ring 43, and then the first motor 323 is started. The first motor 323 drives the winch 324 to rotate. The winch 324 drives the connecting rope 325 to wind. The connecting rope 325 drives the hook 31 to rise. The hook 31 drives the end cover 2 to rise through the auxiliary mechanism 4. When the end cover 2 rises to the specified height, the second motor 531 is started. The second motor 531 drives the first bevel gear 532 to rotate. The first bevel gear 532 drives the second bevel gear 533 to rotate. The second bevel gear 533 drives the rotating rod 321 to rotate, thereby driving the end cover 2 to rotate.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
