Description

Technical Field

[0001] This utility model belongs to the field of air preheater technology, and in particular relates to an air preheater for natural gas heating boilers. Background Technology

[0002] A natural gas heating boiler is a device that uses natural gas as fuel to heat water by combustion. It is widely used in home heating, commercial venues and industrial fields. It uses the heat generated by the combustion of natural gas to heat the water in the boiler, and then provides heating through a hot water circulation system (such as underfloor heating or radiators). It can also provide domestic hot water. Existing boiler flue gas contains a large amount of dust. After this dust enters the air preheater, it will adhere to the heat dissipation pipes or fins inside the air preheater, which will greatly reduce the heat exchange efficiency of the air preheater. To address this, we provide an air preheater for natural gas heating boilers. Utility Model Content

[0003] The purpose of this utility model is to provide an air preheater for a natural gas heating boiler. By replacing the filter element, the reduced filtration effect of the filter element is avoided, which prevents flue gas dust from entering the copper tubes and distribution grooves and covering their surfaces, thereby affecting the heat conduction effect. This solves the problem that a large amount of dust adheres to the heat dissipation pipes or heat dissipation fins inside the existing air preheater, which greatly reduces the heat exchange efficiency of the air preheater.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an air preheater for a natural gas heating boiler, comprising a filtration mechanism and a filter box. The filtration mechanism has a preheating mechanism at its bottom, the filter box has an air inlet at its top and an air outlet at its bottom, a mounting bracket is inserted into the front of the filter box, and a filter element is fixedly connected to the inner wall of the mounting bracket. The mounting bracket has slots on its left and right sides, and the filter box has a compression groove inside to replace the filter element inside the mounting bracket, preventing the filter element from reducing its filtration effect and allowing flue gas dust to enter the copper pipe and the distribution groove, covering their surface and thus affecting the heat conduction effect.

[0005] Furthermore, there are two extrusion grooves. A locking block is slidably connected to the inner wall of the extrusion groove. The locking block is in contact with the inner wall of the groove. The end of the locking block that is far away from the locking block is fixedly connected to the extrusion groove. The end of the extrusion groove that is far away from the locking block is fixedly connected to the inner wall of the extrusion groove. The mounting bracket is limited by the cooperation between the locking block and the groove.

[0006] Furthermore, a push plate is fixedly connected to the front of the card block. The front of the push plate penetrates through the filter box and extends to the outside. The mounting bracket is located on the left side of the air inlet and on the right side of the air outlet. The filtered hot air is sent to the inside of the diversion trough through the air outlet.

[0007] Furthermore, the preheating mechanism includes a preheating box fixedly connected to the bottom of the filter box. The preheating box has a diversion channel inside, and a plurality of air inlet slots are opened inside the diversion channel. Copper pipes are fixedly connected to the bottom of each air inlet slot. Heat sinks are fixedly connected to the left and right sides of each copper pipe. The heat sinks are used to send the hot air in the copper pipe to the interior of the preheating box.

[0008] Furthermore, a fan is fixedly connected to the left side of the preheating box, an air outlet pipe is fixedly connected to the right side of the preheating box, and an exhaust pipe is fixedly connected to the bottom of the preheating box.

[0009] This utility model has the following beneficial effects: This utility model, by setting a filter element, specifically by pulling the push plate to both sides, causing it to move the locking block and move the spring until the locking block disengages from the slot, and then pulling the mounting bracket to the front, causing it to disengage the filter element from the filter box, and then replacing the filter element inside the mounting bracket, prevents the filter element's filtration effect from decreasing, which would allow flue gas and dust to enter the copper pipe and the diversion groove and cover their surface, thereby affecting the heat conduction effect.

[0010] This invention incorporates copper pipes. Specifically, when hot air enters the distribution channel, it enters the copper pipes. Then, heat dissipation fins on the outside of the copper pipes disperse the heat inside the preheating chamber. Finally, a fan is activated to push the heated air inside the preheating chamber outwards, allowing it to enter a designated area through the air outlet pipe. This prevents the hot air from escaping from the preheating chamber and thus affecting the utilization of the heat.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, this utility model is an air preheater for a natural gas heating boiler, including a filter mechanism 1 and a filter box 101. A preheating mechanism 2 is located at the bottom of the filter mechanism 1. An air inlet 102 is located at the top of the filter box 101, and an air outlet 103 is located at the bottom of the filter box 101. A mounting bracket 104 is inserted into the front of the filter box 101, and a filter element 110 is fixedly connected to the inner wall of the mounting bracket 104. Slots 105 are located on both the left and right sides of the mounting bracket 104. An extrusion groove 106 is located inside the filter box 101 to... The push plate 108 is pulled to both sides, causing the locking block 107 to move and the spring 109 to move until the locking block 107 disengages from the slot 105. Then the mounting bracket 104 is pulled to the front, causing the filter element 110 to disengage from the filter box 101. Then the filter element 110 inside the mounting bracket 104 is replaced to prevent the filter element 110 from reducing its filtration effect, which would allow flue gas dust to enter the copper pipe 205 and the diversion groove 202 and cover their surfaces, thus affecting the heat conduction effect.

[0017] There are two extrusion grooves 106. A locking block 107 is slidably connected to the inner wall of the extrusion groove 106, and the locking block 107 is in contact with the inner wall of the groove 105.

[0018] One end of the card block 107 that is far away from the other end is fixedly connected to the compression groove 106, and the end of the compression groove 106 that is far away from the card block 107 is fixedly connected to the inner wall of the compression groove 106.

[0019] The front of the card block 107 is fixedly connected to the push plate 108, which penetrates the filter box 101 and extends to the outside. The mounting bracket 104 is located on the left side of the air inlet 102 and on the right side of the air outlet 103.

[0020] The preheating mechanism 2 includes a preheating box 201 fixedly connected to the bottom of the filter box 101, and a diversion channel 202 is provided inside the preheating box 201.

[0021] The distribution channel 202 has several air inlet slots 207 inside, and copper pipes 205 are fixedly connected to the bottom of each air inlet slot 207. Heat sinks 206 are fixedly connected to the left and right sides of the copper pipes 205. When hot air enters the distribution channel 202, it enters the copper pipes 205, and then the heat sinks 206 on the outside of the copper pipes 205 disperse the heat inside the copper pipes 205 into the preheating box 201. Then, the fan 203 is started to push the heated air inside the preheating box 201 to the outside, so that it enters the designated area through the air outlet duct 204, thus preventing the hot air from escaping from the preheating box 201 and affecting the utilization of the hot air.

[0022] A fan 203 is fixedly connected to the left side of the preheating box 201, an air outlet pipe 204 is fixedly connected to the right side of the preheating box 201, and an exhaust pipe 208 is fixedly connected to the bottom of the preheating box 201.

[0023] A specific application of this embodiment is as follows: In use, first connect the boiler exhaust pipe to the top of the air inlet 102. The hot air generated by the boiler will enter the mounting bracket 104 through the air inlet 102. When the hot air enters the mounting bracket 104, it will be filtered by the filter element 110 to intercept and filter the dust in the hot air. Then, it will enter the diversion groove 202 through the exhaust port 103. When the filter element 110 needs to be replaced, first pull the push plate 108 to both sides to move the locking block 107 and move the spring 109 until the locking block 107 disengages from the locking slot 105. Then, pull the mounting bracket 104 forward to remove the filter element 110 from the filter box 101. Then, the filter element 110 inside the mounting bracket 104 is replaced to prevent the filter element 110 from reducing its filtration effect and causing flue gas and dust to enter the copper pipe 205 and the diversion groove 202 and cover their surfaces, thus affecting the heat conduction effect. When hot air enters the diversion groove 202, it will enter the copper pipe 205, and then the heat dissipation fins 206 on the outside of the copper pipe 205 will disperse the heat inside the copper pipe 205 into the preheating box 201. Then, the fan 203 is started to push the hot air heated inside the preheating box 201 to the outside, so that it enters the designated area through the air outlet duct 204, preventing the hot air from escaping from the preheating box 201 and affecting the utilization effect of the hot air.
