Description

Technical Field

[0001] This utility model relates to the field of heating pipeline technology, specifically to a supply and return pipeline structure for heating. Background Technology

[0002] Heating is a centralized insulation measure that uses heat sources, pipe networks, heat exchange stations, and other facilities to ensure building heating by transmitting heat energy. It is mainly used for winter heating in northern cities. The system typically uses energy sources such as coal, natural gas, electricity, or solar energy, and achieves heat supply through heat source conversion, pipe network distribution, and user-end heat dissipation. It has technical characteristics such as large scale, environmental protection, and intelligence.

[0003] Patent No. 202422329809.0 discloses a supply and return pipe structure for heating. This device improves the sealing performance of the connecting pipe by setting a pipe cover, sealing ring and fixing bolt, and at the same time facilitates the removal of the filter component from the connecting pipe, making it easier for workers to clean.

[0004] However, existing heating supply and return pipe structures use filter components such as filter frames and filter screens to filter the hot water in the pipes. However, the filter structure is fixed to the pipe using pipe covers, sealing rings, and fixing bolts. When disassembling and cleaning the filter structure, it is necessary to first remove the pipe covers, sealing rings, and fixing bolts to take the filter structure out of the pipe for cleaning, and then put the cleaned filter structure back into the pipe, and then fix the filter structure in the pipe again using pipe covers, sealing rings, and fixing bolts. The operation steps are cumbersome and the workload is large, which has a certain impact on heating efficiency. Therefore, a new heating supply and return pipe structure is needed. Utility Model Content

[0005] In view of the problems in the background art, this utility model provides a supply and return pipe structure for heating.

[0006] The technical solution adopted by this utility model to solve its technical problem is a supply and return pipe structure for heating, including a supply and return pipe A and a supply and return pipe B. A fixing bracket for connecting the supply and return pipe B is bolted to one side of the supply and return pipe A. A branch pipe A is screwed to the bottom outer side of the supply and return pipe A. A connecting pipe is screwed to the bottom outer side of the supply and return pipe A, and the end of the connecting pipe is screwed to the top outer side of the supply and return pipe B. A branch pipe B is screwed to the bottom outer side of the supply and return pipe B. A motor is bolted to the outside of the fixing bracket, and a support rod is keyed to the power output end of the motor. A gear is splined to the outside of the support rod, and a drive plate A and a drive plate B are symmetrically meshed to the outside of the gear. A cylinder frame A is welded to the end of the drive plate A and is located inside the supply and return pipe A. A cylinder frame B is welded to the end of the drive plate B and is located inside the supply and return pipe B. A filter frame A is screwed to the inside of the cylinder frame A, and a filter frame B is screwed to the inside of the cylinder frame B.

[0007] By adopting the above technical solution, hot water enters the supply and return pipe A through branch pipe A, then the hot water passes through the filter frame A in the cylinder A to filter the hot water, and then the filtered hot water is transported to the supply and return pipe B through the connecting pipe, and then discharged through the supply and return pipe B. When cleaning the filter rack A inside the cylinder frame A, the motor outside the fixed frame drives the gear outside the support rod to rotate. The gear meshes with the drive plate A and the drive plate B. The drive plate A then moves the cylinder frame A longitudinally upward inside the supply and return pipe A, causing the cylinder frame A to move the filter rack A out. At the same time, the drive plate B moves the cylinder frame B longitudinally downward inside the supply and return pipe B, causing the cylinder frame B to move the filter rack B into the supply and return pipe B. This makes it easier to replace the filter rack and improves heating efficiency. Both filter frame A and filter frame B have a multi-layer filter structure.

[0008] Specifically, rubber rings A are symmetrically fixed to the inner sides of the tube frame A and tube frame B with screws.

[0009] By adopting the above technical solution, when the cylinder frame A and cylinder frame B are removed from the supply and return pipes A and B respectively, the rubber ring A inside the cylinder frame A and cylinder frame B contacts the supply and return pipes A and B respectively. When the supply and return pipes A and B are moved into the supply and return pipes A and B respectively, the rubber ring A inside the cylinder frame A and cylinder frame B contacts the supply and return pipes A and B respectively, thereby improving the sealing performance between the cylinder frame A and cylinder frame B and the supply and return pipes A and B respectively.

[0010] Specifically, both the supply and return pipes A and B have ring plates welded inside.

[0011] By adopting the above technical solution, the ring plates welded inside both the supply and return pipes A and B support the cylinder frame A and cylinder frame B respectively.

[0012] Specifically, a rubber ring B is fixed to the outer side of the ring plate with screws.

[0013] By adopting the above technical solution, when the cylinder frame A contacts the ring plate inside the supply and return pipe A, and the cylinder frame B contacts the ring plate inside the supply and return pipe B, the rubber ring B outside the ring plate has elasticity to fill the gap, thereby improving the sealing performance between the cylinder frame A and the ring plate, and between the cylinder frame B and the ring plate.

[0014] Specifically, the motor input terminal is electrically connected to the power supply terminal of an external power source.

[0015] By adopting the above technical solution, the electrical equipment can operate normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0016] The beneficial effects of this utility model are: (1) The heating supply and return pipe structure described in this utility model, when cleaning the filter frame A in the cylinder frame A, the motor outside the fixed frame drives the gear outside the support rod to rotate, the gear meshes with the drive plate A and the drive plate B, and then the drive plate A drives the cylinder frame A to move longitudinally upward in the supply and return pipe A, so that the cylinder frame A drives the filter frame A to move out, and at the same time the drive plate B drives the cylinder frame B to move longitudinally downward in the supply and return pipe B, so that the cylinder frame B drives the filter frame B to move into the supply and return pipe B, thereby facilitating the replacement of the filter frame and improving the heating efficiency.

[0017] (2) In the heating supply and return pipe structure described in this utility model, when the cylinder frame A and cylinder frame B are moved out from the supply and return pipes A and B respectively, the rubber ring A inside the cylinder frame A and cylinder frame B respectively contacts the supply and return pipes A and B respectively. When the supply and return pipes A and B are moved into the supply and return pipes A and B respectively, the rubber ring A inside the cylinder frame A and cylinder frame B respectively contacts the supply and return pipes A and B respectively, thereby improving the sealing between the cylinder frame A and cylinder frame B and the supply and return pipes A and B respectively. At the same time, when the cylinder frame A3 contacts the ring plate 15 inside the supply and return pipe A5 and the cylinder frame B8 contacts the ring plate 15 inside the supply and return pipe B10, the rubber ring B14 outside the ring plate 15 has elasticity to fill the gap, thereby improving the sealing between the cylinder frame A3 and the ring plate 15 and the cylinder frame B8 and the ring plate 15.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To improve heating efficiency, as one embodiment of this utility model, such as Figures 1 to 2As shown, the present invention discloses a heating supply and return pipe structure, including a supply and return pipe A5 and a supply and return pipe B10. A fixing bracket 4 for connecting the supply and return pipe B10 is bolted to one side of the supply and return pipe A5. A branch pipe A2 is screwed to the bottom outer side of the supply and return pipe A5. A connecting pipe 7 is screwed to the bottom outer side of the supply and return pipe A5, and the end of the connecting pipe 7 is screwed to the top outer side of the supply and return pipe B10. A branch pipe B11 is screwed to the bottom outer side of the supply and return pipe B10. An electric... The motor 6 has a keyed connection to a support rod 16 at its power output end. A gear 17 is externally splined to the support rod 16, and a drive plate A1 and a drive plate B18 are symmetrically meshed externally to the gear 17. A cylinder frame A3 is welded to the end of the drive plate A1, and the cylinder frame A3 is located inside the supply and return pipe A5. A cylinder frame B8 is welded to the end of the drive plate B18, and the cylinder frame B8 is located inside the supply and return pipe B10. A filter frame A12 is screwed to the inside of the cylinder frame A3, and a filter frame B9 is screwed to the inside of the cylinder frame B8.

[0023] In use, hot water enters the supply and return pipe A5 through the branch pipe A2, and then the hot water passes through the filter frame A12 in the cylinder frame A3 to filter the hot water. After that, the filtered hot water is transported to the supply and return pipe B10 through the connecting pipe 7, and then discharged through the supply and return pipe B10. When cleaning the filter rack A12 inside the cylinder frame A3, the motor 6 outside the fixed frame 4 drives the gear 17 outside the support rod 16 to rotate. The gear 17 meshes with the drive plate A1 and the drive plate B18, which in turn drives the cylinder frame A3 to move longitudinally upward in the supply and return pipe A5, so that the cylinder frame A3 moves the filter rack A12 out. At the same time, the drive plate B18 drives the cylinder frame B8 to move longitudinally downward in the supply and return pipe B10, so that the cylinder frame B8 moves the filter rack B9 into the supply and return pipe B10, thereby facilitating the replacement of the filter rack and improving heating efficiency.

[0024] To improve the sealing performance between the cylinder racks A3 and B8 and the supply and return pipes A5 and B10 respectively, for example, as follows: Figure 2 As shown, the present invention also includes rubber rings A13 symmetrically fixed to the inner sides of the tube frame A3 and tube frame B8 by screws.

[0025] During use, when the cylinder frame A3 and cylinder frame B8 are removed from the supply and return pipes A5 and B10 respectively, the rubber rings A13 inside the cylinder frame A3 and cylinder frame B8 contact the supply and return pipes A5 and B10 respectively. When the supply and return pipes A5 and B10 are moved into the supply and return pipes A5 and B10 respectively, the rubber rings A13 inside the cylinder frame A3 and cylinder frame B8 contact the supply and return pipes A5 and B10 respectively, thereby improving the sealing performance between the cylinder frame A3 and cylinder frame B8 and the supply and return pipes A5 and B10 respectively.

[0026] For support of gantry A3 and gantry B8, for example, as follows: Figure 2 As shown, the present invention also includes annular plates 15 welded inside both the supply and return pipes A5 and B10.

[0027] During use, the ring plates 15 welded inside the supply and return pipes A5 and B10 respectively support the cylinder frame A3 and cylinder frame B8.

[0028] To improve the sealing performance between the cylinder frame A3 and the ring plate 15, and between the cylinder frame B8 and the ring plate 15, for example, such as Figure 2 As shown, the present invention also includes a rubber ring B14 fixed to the outer side of the ring plate 15 by screws.

[0029] When in use, when the cylinder frame A3 contacts the ring plate 15 inside the supply and return pipe A5, and the cylinder frame B8 contacts the ring plate 15 inside the supply and return pipe B10, the rubber ring B14 outside the ring plate 15 has elasticity to fill the gap, thereby improving the sealing between the cylinder frame A3 and the ring plate 15, and between the cylinder frame B8 and the ring plate 15.

[0030] For electrical equipment to function properly, for example, such as Figure 1 As shown, this utility model also includes an electric connection between the input terminal of the motor 6 and the power supply terminal of an external power source.

[0031] When in use, the electrical equipment works normally by connecting to an external power source, and all electrical equipment is controlled by the PLC controller.

[0032] In use, hot water enters the supply and return pipe A5 through branch pipe A2, then passes through the filter frame A12 inside the cylinder frame A3 for filtration. The filtered hot water is then transported to the supply and return pipe B10 through connecting pipe 7 and discharged through B10. When cleaning the filter frame A12 inside the cylinder frame A3, the motor 6 outside the fixed frame 4 drives the gear 17 outside the support rod 16 to rotate. The gear 17 meshes with the drive plate A1 and drive plate B18, causing the drive plate A1 to move the cylinder frame A3 longitudinally upwards within the supply and return pipe A5, thus moving the filter frame A12 out of the cylinder frame A3. Simultaneously, the drive plate B18 moves the cylinder frame B8 within the supply and return pipe B10. The inner longitudinal downward movement causes the cylinder frame B8 to move the filter frame B9 into the supply and return pipe B10, thereby facilitating the replacement of the filter frame and improving heating efficiency. When the cylinder frame A3 and cylinder frame B8 move out of the supply and return pipes A5 and B10 respectively, the rubber rings A13 inside the cylinder frame A3 and cylinder frame B8 contact the supply and return pipes A5 and B10 respectively. When the supply and return pipes A5 and B10 move into the supply and return pipes A5 and B10 respectively, the rubber rings A13 inside the cylinder frame A3 and cylinder frame B8 contact the supply and return pipes A5 and B10 respectively, thereby improving the sealing between the cylinder frame A3 and cylinder frame B8 and the supply and return pipes A5 and B10 respectively.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
