Description

Technical Field

[0001] The present application relates to the field of ground source heat pump systems, and in particular to an ultrasonic ground source heat pump descaling and antiscaling device. Background Art

[0002] At present, the geothermal system is a new type of temperature regulation circulation system. Since the surface temperature is higher than the shallow underground temperature in summer and lower than the shallow underground temperature in winter, it uses the geothermal resources in the shallow underground as a source of cold and heat to achieve cold and heat circulation between the shallow underground and the surface.

[0003] The ground source heat pump system consists of a ground heat exchanger, a heat pump unit, an indoor distribution system, a control system and other auxiliary equipment. The ground heat exchanger is used to exchange heat with the soil under the surface, and contains pipes for passing refrigerant or water. The heat pump unit includes components such as evaporation, compressor, condenser and expansion valve to achieve heat exchange with the ground heat exchanger. The indoor distribution system, control system and other auxiliary equipment are used to distribute heat to each room on the ground.

[0004] Since there is more heat exchange between liquid media in the whole system, longer pipes are needed to pass the liquid media. And since the liquid media needs to pass through the whole ground source heat pump system for a long time, it may eventually cause more scale to remain in the system pipes to affect the heat exchange efficiency, thus reducing the overall efficiency. Operators usually clean the pipes by flushing.

[0005] With regard to the above-mentioned related technologies, the valves at different positions in the ground source heat pump system need to be repeatedly opened and closed during the flushing process, and a large amount of water is consumed for flushing, which leads to complicated and inefficient operations for operators. Utility Model Content

[0006] In order to clean and prevent scale inside a ground source heat pump system and simplify the operating procedures of operators to improve cleaning efficiency, the present application provides an ultrasonic ground source heat pump descaling and antiscaling device.

[0007] The present application provides an ultrasonic ground source heat pump descaling and anti-scaling device, which adopts the following technical solution:

[0008] An ultrasonic ground source heat pump descaling and anti-scaling device comprises a ring and a storage table, an ultrasonic transducer assembly is arranged inside the ring, the ultrasonic transducer assembly comprises a shell, an electrode layer, a piezoelectric crystal layer, a sound absorbing material layer and a matching layer, an ultrasonic generator connected to the ultrasonic transducer assembly is arranged outside the ring, a fixing assembly for fixing the ring to a pipeline is arranged outside the ring, the storage table is located on one side of the ring, the storage table is provided with a control assembly for controlling the ultrasonic generator, and the ultrasonic generator is located inside the control assembly.

[0009] By adopting the above technical solution, when descaling the inside of the pipeline, the ultrasonic transducer component is fixed and installed through the holding ring and the fixing component, and the ultrasonic transducer component and the ultrasonic generator are controlled by the control component on the storage table to generate ultrasonic waves to clean the scale inside the pipe. The ultrasonic descaling speed and cleaning degree are much higher than flushing, which effectively reduces the difficulty and complexity of the operator's operation during the descaling process and effectively improves the descaling efficiency.

[0010] Optionally, the outer shell is an arc-shaped outer shell, and an arc surface is provided on the arc-shaped outer shell near the center of the holding ring. The piezoelectric crystal layer is located between the arc-shaped outer shell and the holding ring, the electrode layer is located on both sides of the piezoelectric crystal layer close to the arc-shaped outer shell and the holding ring, and the sound-absorbing material layer is located on one side of the piezoelectric crystal layer close to the holding ring. The sound-absorbing material layer is used to fill the gap between the arc-shaped outer shell and the piezoelectric crystal layer.

[0011] By adopting the above technical solution, when the pipeline is descaling, the arc-shaped shell abuts against the pipeline, and the electrode layers on both sides of the piezoelectric crystal layer are used to apply AC voltage, thereby causing the piezoelectric crystal layer to vibrate. The sound-absorbing material layer around the piezoelectric crystal layer can effectively absorb ultrasonic waves transmitted in the opposite direction and reflect them back to the piezoelectric crystal layer to improve the emission efficiency. By making the arc-shaped shell fit the pipeline as much as possible, the efficiency of ultrasonic transmission is effectively improved.

[0012] Optionally, an opening is provided on one side of the holding ring, and the arc-shaped shell is divided into two sections. The two sections of the arc-shaped shell are evenly arranged on the inner side of the holding ring along the opening direction of the holding ring. The fixing component is located at the opening. A plurality of adjusting screws are provided between the holding ring and the arc-shaped shell. The holding ring is provided with threaded holes adapted to the adjusting screws, and the threaded holes correspond to the adjusting screws one by one. A bearing is provided on the side of the adjusting screw close to the arc-shaped shell, and the arc-shaped shell is provided with a mounting hole for fixing the bearing.

[0013] By adopting the above technical solution, when descaling pipes of different thicknesses, the operator rotates the adjusting screw to control the distance between the arc-shaped outer shell and the holding ring, thereby adjusting the spacing between the arc-shaped outer shells at both ends, and then adapting to pipes of different thicknesses through different spacings, effectively making the device suitable for pipelines of different thicknesses.

[0014] Optionally, the fixing assembly includes a quick buckle, and the holding ring is provided with a quick-fitting socket.

[0015] By adopting the above technical solution, when the descaling pipe needs to be descaled, the installation relationship between the buckle and the socket is loosened, thereby loosening the fixing component, making it easier for the operator to open the ring to move the device to other positions in the pipe.

[0016] Optionally, the outer shell is a cylindrical outer shell, and the electrode layer, piezoelectric crystal layer, sound absorbing material layer and matching layer are arranged in sequence inside the cylindrical outer shell, and three cylindrical outer shells are evenly arranged along the inner side of the holding ring. The cylindrical outer shell extends toward the center of the holding ring, and the cylindrical outer shell and the pipeline are both provided with flanges for connection.

[0017] By adopting the above technical solution, the assembled shell is connected to the pipeline through a flange. When descaling the inside of the pipeline, the ultrasonic transducer components in the three columnar shells work simultaneously. By directly contacting the columnar shell with the medium, the efficiency of ultrasonic transmission is significantly improved, thereby effectively improving the descaling efficiency.

[0018] Optionally, the holding ring includes three sections of mounting rings, the mounting rings correspond to the columnar shell one by one, an insert block is provided at one end of the mounting ring, and a slot adapted to the insert block is provided at the other end of the mounting ring.

[0019] By adopting the above technical solution, when in practice, the plugs of two adjacent mounting rings are inserted into the slots, and then the three sections of mounting rings are assembled into a holding ring, so as to fix one end of the columnar shell principle pipe, effectively reducing the vibration during use to improve the stability of the installation.

[0020] Optionally, the fixing assembly includes an auxiliary fixing rod, one end of which is fixedly connected to the holding ring, and one end of the auxiliary fixing rod close to the inner side of the holding ring is provided with a magnet adapted to the pipe.

[0021] By adopting the above technical solution, the holding ring is fixed on the pipeline through the auxiliary fixing rod. Since the holding ring is attracted to the pipeline by the magnet, it plays an auxiliary supporting role for the structural strength of the installation.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When descaling the inside of the pipe, the ultrasonic transducer assembly is fixed and installed through the holding ring and the fixing assembly, and the ultrasonic transducer assembly and the ultrasonic generator are controlled through the control assembly on the storage table to generate ultrasonic waves to clean the scale inside the pipe. The ultrasonic descaling speed and cleaning degree are much higher than flushing, which effectively reduces the difficulty and complexity of the operator's operation during the descaling process and effectively improves the descaling efficiency;

[0024] 2. When descaling the pipeline, the arc-shaped shell is in contact with the pipeline, and the electrode layers on both sides of the piezoelectric crystal layer are used to apply AC voltage, thereby causing the piezoelectric crystal layer to vibrate. The sound-absorbing material layer around the piezoelectric crystal layer can effectively absorb the ultrasonic waves transmitted in the opposite direction and reflect them back to the piezoelectric crystal layer to improve the emission efficiency. By making the arc-shaped shell fit the pipeline as much as possible, the efficiency of ultrasonic transmission is effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] Embodiment 1:

[0032] The embodiment of the present application discloses an ultrasonic ground source heat pump descaling and antiscaling device.

[0033] Reference Figure 1 and Figure 2 An ultrasonic ground source heat pump descaling and anti-scaling device comprises a ring 1 and a storage table 2, an ultrasonic transducer assembly inside the ring 1, the ultrasonic transducer assembly comprises a shell 3, an electrode layer 311, a piezoelectric crystal layer 312, a sound absorbing material layer 313 and a matching layer 314, an ultrasonic generator connected to the ultrasonic transducer assembly is arranged on the outside of the ring 1, a fixing assembly 4 for fixing the ring 1 on the pipe 101 is arranged on the outside of the ring 1, the storage table 2 is located on one side of the ring 1, the storage table 2 is provided with a control assembly 21 for controlling the ultrasonic generator, and the ultrasonic generator is located inside the control assembly 21. When descaling the inside of the pipe 101, the ultrasonic transducer assembly is fixed and installed by the ring 1 and the fixing assembly 4, and the ultrasonic transducer assembly and the ultrasonic generator are controlled by the control assembly 21 on the storage table 2 to generate ultrasonic waves to clean the scale inside the pipe, and the ultrasonic descaling speed and cleaning degree are much higher than flushing, which effectively reduces the difficulty and complexity of the operation of the operator during the descaling process and effectively improves the descaling efficiency.

[0034] Reference Figure 1 and Figure 2 In order to reduce the distance between the housing 3 and the pipe 101 as much as possible and make them fit well, a good descaling efficiency and effect have been achieved. The housing 3 is an arc housing 313, and the arc housing 313 is provided with an arc surface near the center of the ring 1. The piezoelectric crystal layer 312 is located between the arc housing 313 and the ring 1, and the electrode layer 311 is located on both sides of the piezoelectric crystal layer 312 close to the arc housing 313 and the ring 1. The sound absorbing material layer 313 is located on the side of the piezoelectric crystal layer 312 close to the ring 1, and the sound absorbing material layer 313 is used to fill the gap between the arc housing 313 and the piezoelectric crystal layer 312. When descaling the pipe 101, the arc-shaped shell 313 abuts against the pipe 101, and the electrode layers 311 on both sides of the piezoelectric crystal layer 312 are used to apply an AC voltage, thereby causing the piezoelectric crystal layer 312 to vibrate. The sound-absorbing material layer 313 around the piezoelectric crystal layer 312 can effectively absorb ultrasonic waves transmitted in the opposite direction and reflect them back to the piezoelectric crystal layer 312 to improve the emission efficiency. By making the arc-shaped shell 313 fit the pipe 101 as much as possible, the efficiency of ultrasonic wave transmission is improved.

[0035] Reference Figure 1 and Figure 2 , due to the use of the holding ring 1, the operator can disassemble the device relatively quickly and move it to other pipes 101 for descaling. An opening is provided on one side of the holding ring 1, and the arc-shaped shell 313 is divided into two sections. The two sections of the arc-shaped shell 313 are evenly arranged on the inner side of the holding ring 1 along the opening direction of the holding ring 1. The fixing component 4 is located at the opening. A plurality of adjusting screws 32 are provided between the holding ring 1 and the arc-shaped shell 313. The holding ring 1 is provided with threaded holes adapted to the adjusting screws 32. The threaded holes correspond to the adjusting screws 32 one by one. A bearing 321 is provided on the side of the adjusting screw 32 close to the arc-shaped shell 313. The arc-shaped shell 313 is provided with a mounting hole for fixing the bearing 321. When descaling pipes 101 of different thicknesses, the operator rotates the adjusting screw 32 to control the distance between the arc-shaped shell 313 and the holding ring 1, thereby adjusting the spacing between the arc-shaped shells 313 at both ends, and then adapting to pipes 101 of different thicknesses through different spacings, so that the device is suitable for pipes 101 of different thicknesses.

[0036] Reference Figure 1 and Figure 2 Since the device needs to be disassembled and installed, in order to facilitate the operator to disassemble and install the device. The fixing component 4 includes a quick buckle 41, and the ring 1 is provided with a holder 42 for quick adaptation. When the descaling pipe 101 needs to be descaled, the installation relationship between the buckle and the holder 42 is loosened, and the fixing component 4 is loosened, so that the operator can open the ring 1 to move the device to other positions of the pipe 101.

[0037] Embodiment 2:

[0038] In this embodiment, the biggest difference is the shape of the housing 3 and the shape of the holding ring 1 .

[0039] Reference Figure 3 and Figure 4 In order to further improve the efficiency of descaling, the scale is removed by direct contact between the housing 3 and the medium. The housing 3 is a cylindrical housing 333. The electrode layer 311, the piezoelectric crystal layer 312, the sound absorbing material layer 313 and the matching layer 314 are sequentially arranged inside the cylindrical housing 333. Three cylindrical housings 333 are evenly arranged along the inner side of the ring 1. The cylindrical housing 333 extends toward the center of the ring 1. The cylindrical housing 333 and the pipe 101 are both provided with flanges 331 for connection. The assembled housing 3 is connected to the pipe 101 through the flange 331. When descaling the inside of the pipe 101, the ultrasonic transducer components in the three cylindrical housings 333 work at the same time. The direct contact between the cylindrical housing 333 and the medium significantly improves the efficiency of ultrasonic transmission, thereby improving the efficiency of descaling.

[0040] Reference Figure 3 and Figure 4 In order to fix and limit the other end of the columnar housing 333 to reduce the vibration generated when the device is used. The holding ring 1 includes three sections of mounting rings 11, and the mounting rings 11 correspond to the columnar housing 333 one by one. One end of the mounting ring 11 is provided with an insert block 43, and the other end of the mounting ring 11 is provided with a slot 44 adapted to the insert block 43. When practical, the insert blocks 43 of the adjacent mounting rings 11 are inserted into the slot 44, and then the three sections of the mounting rings 11 are assembled into the holding ring 1, so as to fix one end of the principle pipe 101 of the columnar housing 333, effectively reduce the vibration during use, and improve the stability of the installation.

[0041] Reference Figure 3 and Figure 4 , in order to further strengthen the installation rigidity between the mounting rings 11, so as to improve the stability of the columnar housing 333. The fixing assembly 4 includes an auxiliary fixing rod 5, one end of which is fixedly connected to the holding ring 1, and the end of the auxiliary fixing rod 5 close to the inner side of the holding ring 1 is provided with a magnet 51 adapted to the pipe 101.
