Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving heating pipes, and more specifically, the utility model relates to an energy-saving heat pump heating pipe. Background Art

[0002] A heat pump is a mechanical device that converts low-temperature heat energy into high-temperature heat energy to achieve a heating effect. During the process of transporting the medium, a heat pump needs to use a heating pipe.

[0003] However, when the existing heating pipe is in use, since a large amount of heat leaks from the side wall of the pipe, if the heat cannot be effectively collected, the utilization efficiency of the heat will be reduced, thereby reducing the overall practicality.

[0004] After retrieval, a Chinese patent with the authorization announcement number CN218379593U discloses an energy-saving heat pump heating pipe. Under the action of the collection sleeve, the waste heat transferred from the heat preservation pipe can be collected into the circulating water in the collection tank, and then the circulating water is discharged, so as to export the waste heat and improve the utilization rate of the heat.

[0005] However, when this structure is actually used, once there are impurities in the medium transported inside the heat preservation pipe or the temperature changes during the waste heat recovery period, it is easy to cause the phenomenon of scaling on the inner wall of the heat preservation pipe, which is difficult to clean and will affect the transportation effect of the heat preservation pipe in the long term. In view of this, the utility model provides an energy-saving heat pump heating pipe. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides an energy-saving heat pump heating pipe to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: An energy-saving heat pump heating pipe includes a heat preservation pipe connected to a heat pump. A collection sleeve is sleeved outside the heat preservation pipe, and the collection sleeve fits on the outside of the heat preservation pipe. A plurality of heat conduction strips are distributed annularly on the outer surface of the heat preservation pipe, and a plurality of heat conduction grooves are distributed annularly on the inner wall of the collection sleeve. The heat conduction strips are slidably installed inside the heat conduction grooves. A flow groove is spirally formed inside the collection sleeve. A liquid inlet pipe is communicated with the surface of the collection sleeve, and a liquid outlet pipe is arranged on one side of the liquid inlet pipe. One ends of the liquid inlet pipe and the liquid outlet pipe are respectively communicated with both ends of the flow groove.

[0008] It can be seen that in this structure, the collection sleeve is installed outside the heat preservation pipe. The waste heat on the surface of the heat preservation pipe is conducted to the collection sleeve through the heat conduction strips and the heat conduction grooves, heating the circulating water spirally transported inside the collection sleeve, achieving the purpose of recovering the waste heat on the surface of the heat preservation pipe and improving the energy-saving performance of the heating pipe.

[0009] In order to achieve the purpose of removing scale from the inner wall of the heat-insulating pipe and avoid affecting the transportation of the medium by the heat-insulating pipe, preferably, a descaling structure is provided inside the heat-insulating pipe. The descaling structure includes a support seat, which is fixedly installed at one end inside the heat-insulating pipe. A bearing seat is provided at the other end inside the heat-insulating pipe. A transmission lead screw is arranged between the support seat and the bearing seat. A threaded block is arranged outside the transmission lead screw. A descaling ring is arranged outside the threaded block. Two connecting rods are arranged between the threaded block and the descaling ring. A turntable is arranged at one end of the transmission lead screw. Two guiding grooves are formed on the inner wall of the heat-insulating pipe. Two guiding blocks are arranged on the surface of the descaling ring. The transmission lead screw is rotatably connected between the support seat and the bearing seat, and one end of the transmission lead screw is fixedly connected to the turntable. The threaded block is threadedly connected to the outside of the transmission lead screw. The threaded block and the descaling ring are connected by two connecting rods. The outer wall of the descaling ring is attached to the inner wall of the heat-insulating pipe. The guiding blocks on the surface of the descaling ring are adapted to the guiding groove structure on the inner wall of the heat-insulating pipe, and the guiding blocks are slidably connected inside the guiding grooves.

[0010] The technical effects and advantages of the present utility model:

[0011] 1. By providing a descaling structure, the rotation of the transmission lead screw causes the threaded block to drive the descaling ring to move along the inner wall of the heat-insulating pipe through the connecting rod. The descaling ring is slidably guided along the inner wall of the heat-insulating pipe through the guiding blocks and guiding grooves, and can scrape off the dirt attached to the inner wall of the heat-insulating pipe, thereby avoiding the generation of a large amount of scale on the inner wall of the heat-insulating pipe and affecting the use effect of the heat-insulating pipe, and facilitating the cleaning operation of the operator on the heat-insulating pipe;

[0012] 2. Through multiple heat conduction strips and heat conduction grooves, the waste heat on the surface of the heat-insulating pipe is conducted to the surface of the collection sleeve, and the circulating water in the flow grooves of the collection sleeve is heated, and finally discharged through the liquid outlet pipe, achieving the effect of recycling the heat on the surface of the heat-insulating pipe, avoiding waste of heat, and achieving the purpose of energy saving. The spiral flow grooves can increase the flow time of the circulating water and improve the heat recovery effect. Description of the drawings

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As shown in the attached Figures 1-5 An energy-saving heat pump heating pipe shown includes a heat preservation pipe 1 connected to a heat pump. A collection sleeve 2 is sleeved outside the heat preservation pipe 1. The collection sleeve 2 fits on the outside of the heat preservation pipe 1. A plurality of heat conduction strips 12 are annularly distributed on the outer surface of the heat preservation pipe 1. A plurality of heat conduction grooves 13 are annularly distributed on the inner wall of the collection sleeve 2. The heat conduction strips 12 are slidably installed inside the heat conduction grooves 13. A spiral flow groove 14 is formed inside the collection sleeve 2. A liquid inlet pipe 15 is communicated with the surface of the collection sleeve 2. And a liquid outlet pipe 16 is arranged on one side of the liquid inlet pipe 15. One ends of the liquid inlet pipe 15 and the liquid outlet pipe 16 are respectively communicated with both ends of the flow groove 14.

[0021] Specifically, in this structure, the heat preservation pipe 1 is connected to the heat pump to achieve the transportation of the heating medium. The plurality of heat conduction strips 12 on the heat preservation pipe 1 are respectively slid into the heat conduction grooves 13 opened by the collection sleeve 2, so that the collection sleeve 2 is installed outside the heat preservation pipe 1. Circulating water flows inside the liquid inlet pipe 15, so that the circulating water flows through the spiral flow groove 14 and finally circulates out through the liquid outlet pipe 16;

[0022] During the process of the heat preservation pipe 1 transporting the heating medium, the heat on the surface of the heat preservation pipe 1 will be conducted to the inside of the collection sleeve 2 through the plurality of heat conduction strips 12 and the heat conduction grooves 13, and heat the circulating water inside the flow groove 14 belonging to the collection sleeve 2, achieving the effect of recycling the heat on the surface of the heat preservation pipe 1, avoiding waste of heat, and achieving the purpose of energy saving. The spiral flow groove 14 can increase the flow time of the circulating water and improve the heat recovery effect.

[0023] In a specific embodiment, as shown in the attached Figure 1 、 3, as shown in Figures 4, a descaling structure is provided inside the heat preservation pipe 1. The descaling structure includes a support base 3, which is fixedly installed at one end inside the heat preservation pipe 1. A bearing seat 4 is provided at the other end inside the heat preservation pipe 1. A transmission screw rod 5 is arranged between the support base 3 and the bearing seat 4. A threaded block 6 is arranged outside the transmission screw rod 5. A descaling ring 7 is arranged outside the threaded block 6. Two connecting rods 8 are arranged between the threaded block 6 and the descaling ring 7. A turntable 9 is arranged at one end of the transmission screw rod 5. Two guiding grooves 10 are formed on the inner wall of the heat preservation pipe 1. Two guiding blocks 11 are arranged on the surface of the descaling ring 7. The transmission screw rod 5 is rotatably connected between the support base 3 and the bearing seat 4, and one end of the transmission screw rod 5 is fixedly connected to the turntable 9. The threaded block 6 is threadedly connected to the outside of the transmission screw rod. The threaded block 6 and the descaling ring 7 are connected by two connecting rods 8. The outer wall of the descaling ring 7 is attached to the inner wall of the heat preservation pipe 1. The guiding block 11 on the surface of the descaling ring 7 is adapted to the structure of the guiding groove 10 on the inner wall of the heat preservation pipe 1, and the guiding block 11 is slidably connected inside the guiding groove 10.

[0024] Specifically, in this structure, once there are impurities in the heat supply medium inside the heat preservation pipe 1, or during the heat recovery process, due to temperature changes, the inner wall of the heat preservation pipe 1 has a structural phenomenon. In order to facilitate the removal of the dirt on the inner wall of the heat preservation pipe 1, specifically;

[0025] The entire heat preservation pipe 1 is removed from the heat pump. By rotating the turntable 9 at one end of the heat preservation pipe 1, the transmission screw rod 5 rotates between the bearing seat 4 and the support base 3. The rotation of the transmission screw rod 5 causes the threaded block 6 to move. Since the threaded block 6 is connected to the descaling ring 7 through two connecting rods 8, and the guiding block 11 on the surface of the descaling ring 7 slides and guides inside the guiding groove 10 on the inner wall of the heat preservation pipe 1, therefore, the rotation of the descaling ring 7 following the threaded block 6 will be restricted, causing the threaded block 6 to move horizontally on the outside of the transmission screw rod 5. Furthermore, the threaded block 6 drives the descaling ring 7 to move while adhering to the inner wall of the heat preservation pipe 1 through the connecting rod 8, scraping off the dirt generated on the inner wall of the heat preservation pipe 1, avoiding a large amount of scale formation on the inner wall of the heat preservation pipe 1, affecting the conveying effect of the heat preservation pipe 1, and facilitating the operator to clean.

[0026] Specifically, this structure is inside the heat preservation pipe 1 and will not affect the normal use of the heat preservation pipe 1.

[0027] The working principle of the present utility model:

[0028] The present application provides an energy-saving heat pump heating pipe. During specific use, the heat preservation pipe 1 is connected to the heat pump to achieve the transportation of the heating medium. A plurality of heat conduction strips 12 on the heat preservation pipe 1 are respectively slid into the heat conduction grooves 13 opened in the collection sleeve 2, so that the collection sleeve 2 is installed outside the heat preservation pipe 1. Circulating water flows inside the liquid inlet pipe 15, so that the circulating water flows through the spiral flow groove 14 and finally circulates out through the liquid outlet pipe 16;

[0029] During the process of the heat preservation pipe 1 transporting the heating medium, the heat on the surface of the heat preservation pipe 1 will be conducted to the inside of the collection sleeve 2 through a plurality of heat conduction strips 12 and heat conduction grooves 13, and heat the circulating water inside the flow groove 14 to which the collection sleeve 2 belongs, achieving the effect of recycling the heat on the surface of the heat preservation pipe 1, avoiding waste of heat, and achieving the purpose of energy saving. The spiral flow groove 14 can increase the flow time of the circulating water and improve the heat recovery effect;

[0030] When it is necessary to treat the scale on the inner wall of the heat preservation pipe 1, the whole heat preservation pipe 1 is removed from the heat pump. By rotating the turntable 9 at one end of the heat preservation pipe 1, the transmission lead screw 5 rotates between the bearing seat 4 and the support seat 3, driving the descaling ring 7 to move along the inner wall of the heat preservation pipe 1, scraping off the dirt generated on the inner wall of the heat preservation pipe 1, avoiding a large amount of scale on the inner wall of the heat preservation pipe 1, affecting the transportation effect of the heat preservation pipe 1, and facilitating the operator to clean up.

[0031] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
