[0003] For example, a movable heating device with publication number CN207674582U includes a radiator, a hose and a movable base; an inlet pipe joint and a return pipe joint are provided on the radiator, and the inlet pipe joint and the return pipe joint are respectively connected to a group of branch pipe ends of the outlet pipe and the return pipe of the heating pipe through hoses; the movable base includes a base plate with a slot and adjustable supporting legs and casters; the two ends of the bottom of the radiator are respectively clamped in the slots of the base plate; the hose is a section of retractable connecting pipe, and the hose includes two threaded joints located at both ends of the pipe and a retractable pipe section located in the middle part of the pipe; the inlet pipe joint, the return pipe joint and the ends of each branch pipe of the outlet pipe and the return pipe are all provided with threaded joints that match the threaded joints at both ends of the hose pipe.

[0004] The above patent provides heating by heat conduction through radiators, but hot water circulates in the radiator and gradually produces some dirt. The dirt not only reduces the heat transfer efficiency, but also causes under-scale corrosion and shortens the service life of the equipment. Some existing heating equipment cannot filter the circulating water flow, which is not conducive to equipment maintenance. In addition, the water pipes in the radiator are generally curved structures, and the dirt in the water flow is easy to accumulate at the bends of the curved pipes. The dirt accumulated in the curved pipes is not easy to be discharged independently, which greatly affects the service life of the curved pipes.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original heating equipment. Summary of the invention

[0006] The purpose of the present invention is to provide a circulating filtering heating device to solve the problem in the above background technology that hot water circulates in the radiator and gradually produces some dirt. The dirt not only reduces the heat transfer efficiency, but also causes under-scale corrosion and shortens the service life of the equipment.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a circulating filtering heating device, comprising a radiator for emitting heat, the radiator being provided with a water inlet for controlling the inflow of hot water, the water inlet being connected through a curved tube, the outside of the curved tube being fixedly sleeved with a fixing block, and the curved tube being fixedly installed inside the radiator through the fixing block, the outside of the radiator being connected to the filter through a water outlet pipe, and the water outlet pipe being connected through the curved tube, and a drain pipe being connected through the bottom of the filter, a valve pipe being installed on the drain pipe, the upper end of the valve pipe being connected through a high-pressure return pipe, the high-pressure return pipe being connected through the inside of the filter, and a detector for detecting water quality being installed on the valve pipe; a filtering mechanism for graded filtering of sewage is provided inside the filter.

[0008] Preferably, the filtering mechanism comprises two waterproof electric-driven lifting rods fixed to the inner bottom surface of the filter, a lifting frame is fixed to the output end of the waterproof electric-driven lifting rod, and a filter cover is rotatably mounted on the lifting frame.

[0009] Preferably, three filter covers are arranged inside the filter, the three filter covers are connected to each other by round rods, and the filter aperture sizes of the three filter covers decrease sequentially from top to bottom.

[0010] Preferably, a support frame is fixed to the inner wall of the filter, a positioning ring is fixedly installed on the support frame, and the positioning ring is coaxially distributed with the filter cover; a hollow column is fixed inside the positioning ring, a wave groove is opened on the inner side of the hollow column, and a slide rod is slidably connected in the wave groove; the slide rod is fixedly connected to the round rod.

[0011] Preferably, the radiator is provided with a sewage discharge mechanism for discharging dirt from the inner bending part of the curved tube.

[0012] Preferably, the sewage discharge mechanism includes a sewage discharge pipe fixed in the radiator, and the sewage discharge pipe is connected with the curved pipe; a plurality of rotating rings are rotatably mounted on the outside of the sewage discharge pipe, and two knocking rods are fixedly connected to the rotating rings, and the two knocking rods are located at the front and rear sides of the curved pipe respectively; The multiple rotating rings are fixedly connected to each other via fixing plates.

[0013] Preferably, a motor is fixedly installed in the radiator, a driving bevel gear is connected to the output end of the motor, a bevel gear ring is meshingly connected to the driving bevel gear, and the bevel gear ring is fixed to the outside of the rotating ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: hot water is controlled to enter the curved tube through the water inlet, and the radiator dissipates the heat in the curved tube to the outside, thereby realizing rapid heating. After heating, the hot water flows into the filter through the water outlet pipe, and the internal dirt content of the water flow is reduced after being filtered in the filter, thereby maintaining the water flow for recycling. By providing a filtering mechanism, the filtering mechanism includes three filter covers, and the filter covers are longitudinally distributed in the filter, so as to realize graded filtration of hot water and improve the filtering effect of the water flow; during the filtering process, the waterproof electric drive lifting rod is operated to control the longitudinal reciprocating movement of the lifting frame, and the lifting frame pushes the three filter covers to move up and down reciprocatingly. During the reciprocating movement of the filter cover, the round rod connected to the filter cover moves up and down synchronously, and the round rod pushes the sliding rod to move in the wave groove. While the round rod moves up and down, it rotates in the hollow column along the direction of the wave groove, thereby driving the filter cover to rotate reciprocatingly. Through this part of the transmission, the filter cover can move longitudinally and reciprocate left and right, thereby accelerating the filtering of water by the filter cover. By providing a sewage discharge mechanism, after opening the valve connected between the curved pipe and the sewage discharge pipe, the dirt accumulated at the bend at the bottom of the curved pipe enters the sewage discharge pipe, and is discharged outwards autonomously through the sewage discharge pipe, thereby preventing the dirt from accumulating in the curved pipe; the operating motor controls the bevel gear to rotate, and the swivel is controlled to rotate reciprocally under the gear meshing transmission. The swivel drives the knocking rod to rotate and knock on the outer wall of the curved pipe, causing the curved pipe to vibrate, thereby accelerating the discharge of dirt at the bend at the bottom of the curved pipe, thereby improving the sewage discharge effect.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1-Figure 8 The present invention provides the following technical solutions: a circulating filtering heating device, comprising a radiator 1 for radiating heat, a water inlet 2 for controlling the inflow of hot water installed on the radiator 1, a curved tube 3 connected through the water inlet 2, a fixed block 4 fixedly sleeved on the outside of the curved tube 3, and the curved tube 3 is fixedly installed inside the radiator 1 through the fixed block 4, the outside of the radiator 1 is connected to the filter 6 through the outlet pipe 5, and the outlet pipe 5 is connected through the curved tube 3, and the filter 6 is connected through the drain pipe 7 below. A valve pipe 8 is installed on the drain pipe 7, and a high-pressure return pipe 9 is connected through the upper end of the valve pipe 8, and the high-pressure return pipe 9 is connected through the inside of the filter 6, and a detector 10 for detecting water quality is installed on the valve pipe 8. A filtering mechanism for graded filtering of sewage is arranged inside the filter 6. The filtering mechanism includes two waterproof electric-driven lifting rods 11 fixed on the bottom surface of the inside of the filter 6, and a lifting frame 12 is fixed on the output end of the waterproof electric-driven lifting rod 11, and a filter cover 13 is rotatably installed on the lifting frame 12.

[0019] like Figures 2 to 4 As shown, three filter covers 13 are arranged inside the filter 6, and the three filter covers 13 are connected to each other through round rods 14, and the filter aperture sizes of the three filter covers 13 decrease from top to bottom.

[0020] like Figures 2 to 4 As shown, a support frame 15 is fixed to the inner wall of the filter 6, and a positioning ring 16 is fixedly installed on the support frame 15. The positioning ring 16 is coaxially distributed with the filter cover 13; a hollow column 17 is fixed inside the positioning ring 16, and a wave groove 18 is opened on the inner side of the hollow column 17, and a slide rod 19 is slidably connected in the wave groove 18; the slide rod 19 is fixedly connected to the round rod 14.

[0021] The water inlet 2 and the drain pipe 7 are connected to the water inlet and outlet ports of the heating boiler to control the inflow and outflow of hot water. The hot water enters the curved pipe 3 through the water inlet 2. The hot water in the curved pipe 3 flows, and the heat is transferred to the radiator 1. The heat is dissipated outward through the radiator 1 to achieve the purpose of heating; the hot water flows into the water outlet pipe 5 in the curved pipe 3, and the water flow in the water outlet pipe 5 flows into the filter 6. The filter 6 is provided with three filter covers 13 from top to bottom. The hot water flows in the three filter covers 13 with different aperture sizes for graded filtration. During filtering, the waterproof electric drive lifting rod 11 is driven to push the lifting frame 12 to move up and down reciprocatingly. The lifting frame 12 drives the three filter covers 13 to move up and down synchronously. The round rod 14 connected between the filter covers 13 penetrates the hollow column 17 and moves up and down. Figure 5 As shown, the side of the round rod 14 is connected with a slide bar 19, and the slide bar 19 moves up and down with the round rod 14. When the slide bar 19 moves up and down, it slides and moves along the direction of the wave groove 18, so that the slide bar 19 and the round rod 14 can rotate back and forth in the hollow column 17, and the hollow column 17 drives the filter cover 13 to rotate back and forth synchronously, so that the filter cover 13 can move up and down and rotate back and forth, thereby accelerating the filtering efficiency of the filter cover 13 for hot water; the filtered hot water is discharged outward through the drain pipe 7, and the valve pipe 8 between the drain pipe 7 and the high-pressure return pipe 9 is connected with a detector 10, and the detector 10 can detect the water quality discharged from the drain pipe 7. If the filtered water quality is still not up to standard, open the valve pipe 8 to control the water flow in the drain pipe 7 to flow into the high-pressure return pipe 9. The high-pressure return pipe 9 is provided with a pressure pump, which can control the flow of hot water. The water flow re-enters the filter 6 through the high-pressure return pipe 9, realizes hot water circulation filtration, and improves the filtering effect of the water flow.

[0022] Embodiment 2: Based on Embodiment 1, a sewage discharge mechanism is also disclosed, and its specific structure is as follows: a sewage discharge mechanism for discharging dirt from the inner bend of the curved tube 3 is arranged inside the radiator 1. Figure 6 , Figure 7 As shown, the sewage discharge mechanism includes a sewage discharge pipe 20 fixed in the radiator 1, and the sewage discharge pipe 20 is connected with the curved pipe 3. A plurality of swivels 21 are rotatably mounted on the outside of the sewage discharge pipe 20, and two knocking rods 22 are fixedly connected to the swivels 21, and the two knocking rods 22 correspond to the front and rear sides of the curved pipe 3; the plurality of swivels 21 are fixedly connected to each other through fixing plates 23.

[0023] like Figure 8 As shown, a motor 24 is fixedly installed in the radiator 1 , and a driving bevel gear 25 is connected to the output end of the motor 24 . A bevel gear ring 26 is meshingly connected to the driving bevel gear 25 , and the bevel gear ring 26 is fixed to the outside of the rotating ring 21 .

[0024] The curved part in the curved pipe 3 is prone to accumulate dirt. A valve is connected between the curved pipe 3 and the sewage pipe 20. The valve is opened to control the through connection between the curved pipe 3 and the sewage pipe 20, and the dirt in the curved pipe 3 enters the sewage pipe 20. At the same time, the running motor 24 controls the driving bevel gear 25 to rotate reciprocatingly, and the driving bevel gear 25 is meshed and connected with the bevel gear ring 26. Under the meshing transmission, the bevel gear ring 26 is driven to rotate reciprocatingly, thereby realizing the reciprocating rotation of the rotating ring 21 on the outside of the sewage pipe 20. When the rotating ring 21 reciprocates, it drives the knocking rod 22 to rotate. The knocking rod 22 rotates and knocks on the outer surface of the curved pipe 3, causing the pipe wall of the curved pipe 3 to vibrate, thereby accelerating the discharge of dirt in the curved pipe 3 into the sewage pipe 20.
