Description

Technical Field

[0001] The utility model relates to the technical field related to heat exchange stations, in particular to a heating device for a heat exchange station. Background Art

[0002] The heat exchange station automatically and continuously converts the heat obtained from the primary network into domestic water and heating water required by users. That is, hot water (or steam) enters the plate heat exchanger from the primary side inlet of the unit for heat exchange and then flows out from the primary side outlet of the unit; the secondary side return water passes through the filter to remove dirt, and then enters the plate heat exchanger through the secondary side circulating water pump for heat exchange, producing hot water of different temperatures for heating, air conditioning, floor heating or domestic water to meet user needs.

[0003] The utility model patent with announcement number CN219346624U discloses a mixed water heating device of a heat exchange station, which belongs to the technical field related to heat exchange stations. It solves the problem in the prior art that when performing mixed water heating, in order to avoid clogging of the filter cartridge, the filter cartridge needs to be moved out of the main body before cleaning can be carried out. During this period, the mixed water heating work needs to be stopped because impurities in the water cannot be filtered, which will affect the mixed water heating work. The utility model patent includes a shell of a mixed water heating device, a push rod drives the vertical plate to move horizontally, and then the vertical plate can drive the cross bar to move synchronously. When the cross bar moves horizontally, the vertical rod will contact with multiple groups of protrusions in turn, so that when the vertical rod contacts with the protrusions, the vertical rod will knock on the surface of the filter cartridge, and then the filter cartridge can be vibrated to remove scale and other debris attached to the filter cartridge. Moreover, the cleaning work can be completed when the filter cartridge only filters water, and there is no need to stop the mixed water heating work, which can avoid affecting the mixed water heating work.

[0004] However, the above patent still has shortcomings: this patent uses the coordination between the vertical rod and the protrusion to make the vertical rod slide toward the direction of the filter cartridge when it contacts the protrusion. Because the vertical rod slowly contacts the surface of the filter cartridge when sliding toward the direction of the filter cartridge under the resistance of the protrusion, the vertical rod will not have enough impact force on the filter cartridge, affecting the cleaning effect of the filter device; this patent can only vibrate and clean the impurities on the surface of the filter cartridge through the vertical rod, which may easily cause some of the impurities loosened by the vibration to still accumulate on the filter cartridge and cannot be processed, affecting the cleaning effect of the impurities. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a heat exchange station heating device to solve the problems proposed in the above background technology that the vertical rod has insufficient knocking force on the filter cartridge and some impurities loosened by the shock still accumulate on the filter cartridge and cannot be processed.

[0028] like Figure 2 and Figure 3 As shown, the filter element 2 is an annular structure, and a mounting ring 21 is provided on the outer ring surface of the filter element 2. The outer ring surface of the mounting ring 21 is arranged on the inner tube surface of the output pipe 12. A connecting ring 22 is provided on the inner ring surface of the filter element 2. A connecting block 23 is rotatably provided on the inner ring surface of the connecting ring 22. The water wheel 3 and the cleaning brush 5 are both transmission-connected with the connecting block 23, so that the filter element 2 is installed inside the output pipe 12 through the mounting ring 21. At the same time, the water wheel 3 drives the cleaning brush 5 to rotate on the filter element 2 through the cooperation of the connecting ring 22 and the connecting block 23.

[0029] like Figure 3 As shown, a driving shaft 31 is provided on the water wheel 3, and the driving shaft 31 is connected to the connecting block 23, so that the water wheel 3 drives the connecting block 23 to rotate through the driving shaft 31, and then drives the cleaning brush 5 to rotate on the filter element 2 through the connecting block 23.

[0030] like Figure 3 and Figure 4As shown, the vibration member 4 is arranged on the shaft body of the driving shaft 31, and a vibration cylinder 43 is arranged on the vibration member 4 in a circular array. A limit block 44 is slidably provided inside the vibration cylinder 43, and a return spring 45 is arranged between the limit block 44 and the inner wall of the vibration cylinder 43. A vibration rod 46 is also provided on the limit block 44, and the other end of the vibration rod 46 slides and extends to the side of the vibration cylinder 43 close to the filter element 2. The vibration block 41 is arranged on the rod end of the vibration rod 46 located outside the vibration cylinder 43, and the resistance block 42 is arranged on the mounting ring 21 in a circular array, so that the vibration member 4 is driven to rotate through the driving shaft 31, and then through the cooperation of the vibration member 4, the vibration cylinder 43, the limit block 44, the return spring 45 and the vibration rod 46, the vibration block 41 is separated from the mounting ring 21 under the resistance of the resistance block 42, and the vibration block 41 knocks on the mounting ring 21 after being separated from the resistance block 42.

[0031] like Figure 4 As shown, the vibrating block 41 and the abutting block 42 are both provided with inclined surfaces on their adjacent surfaces, so that the vibrating block 41 can be separated from the mounting ring 21 by the abutting block 42 through the inclined surfaces on the vibrating block 41 and the abutting block 42, and the vibrating block 41 can knock on the mounting ring 21 after being separated from the abutting block 42.

[0032] like Figure 5 and Figure 6 As shown, a linkage shaft 51 is rotatably provided on the cleaning brush 5 , and the linkage shaft 51 is connected to the connecting block 23 , so that the connecting block 23 drives the cleaning brush 5 to rotate on the filter element 2 through the linkage shaft 51 .

[0033] like Figure 6 As shown, the rolling block 6 rolls against the mounting ring 21 , so that the cleaning brush 5 rotates when rotating on the filter element 2 through the cooperation between the rolling block 6 and the mounting ring 21 .

[0034] Working principle: The heating machine 1 processes the water input by the input pipe 11 and outputs it through the output pipe 12. The water output through the output pipe 12 will be filtered out of impurities by the filter 2. The water filtered out of impurities by the filter 2 will drive the water wheel 3 to rotate. When the water wheel 3 rotates, it will drive the driving shaft 31 to rotate. When the driving shaft 31 rotates, it will drive the vibrating member 4 to rotate. When the vibrating member 4 rotates, it will drive the vibrating block 41 to rotate on the mounting ring 21. When the inclined surface of the vibrating block 41 rotates on the mounting ring 21 until it contacts the inclined surface of the contact block 42, When the vibration block 41 slides in the direction of the vibration member 4, it will drive the limit block 44 connected to the vibration rod 46 to squeeze the reset spring 45. When the inclined surface of the vibration block 41 rotates on the mounting ring 21 to be separated from the inclined surface of the resistance block 42, the limit block 44 will drive the vibration block 41 connected to the vibration rod 46 to knock on the mounting ring 21 under the elasticity of the reset spring 45, thereby shaking loose the impurities filtered on the filter element 2.

[0035] When the driving shaft 31 rotates, it will also drive the connecting block 23 to rotate. When the connecting block 23 rotates, it will drive the cleaning brush 5 connected to the linkage shaft 51 to rotate on the filter element 2, so that the impurities loosened on the filter element 2 are swept down by the cleaning brush 5. At the same time, when the cleaning brush 5 rotates on the filter element 2, it will drive the rolling block 6 to roll on the mounting ring 21, so that the cleaning brush 5 rotates on itself when it rotates on the filter element 2, thereby further improving the effect of sweeping down the impurities loosened on the filter element 2. The swept down impurities will fall into the interior of the collecting box 72 through the collecting valve 71 connected to the collecting pipe 7. When it is necessary to clean the impurities collected in the collecting box 72, the collecting valve 71 can be closed to clean the impurities collected in the collecting box 72 without stopping the machine.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
