Description

Technical Field

[0001] This utility model relates to a combustion fireplace, and more specifically, to a ash removal hanging rack structure for a combustion fireplace. Background Technology

[0002] Combustion fireplaces produce a lot of ash during use, so an ash removal system is required.

[0003] For example, a Chinese patent document titled "Dust Removal Structure for Heat Pipes and Real Fireplace," with publication number CN119983919A, was found in the search results. Figure 2 and Figure 3 Its suspension rod 041 suspends the spring 03. The suspension rod 041 and the connecting rod 044 form a dust removal suspension frame. The dust removal suspension frame drives the spring to clean the heat dissipation pipe 01 under the up and down push of 042.

[0004] In the above-mentioned patented solution, when the ash removal suspension frame is parked, the connecting rod 044 and the bottom surface of the conversion chamber 02 abut against each other, causing an ash accumulation area to form between the short edges of the connecting rod 044 and the conversion chamber 02. Due to the blocking effect of the connecting rod 044, the impurities and ash in the ash accumulation area are difficult to enter the heat dissipation pipe 01 for discharge. After years of combustion, the ash layer in the ash accumulation area weakens the downward heat transfer performance of the area. Since the bottom of the conversion chamber 02 is the fresh air outlet for heat exchange, the heating performance of the fresh air will be reduced. Utility Model Content

[0005] The purpose of this utility model is to provide an ash removal hanging frame structure for a combustion fireplace. By using the lifting effect of the gasket, an airflow space is provided between the connecting rod and the base plate, so that the ash on the outside of the connecting rod can flow to the heat dissipation pipe through this space, making it less likely for ash to accumulate on the base plate outside the connecting rod, and the base plate can effectively transfer heat energy downward.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A ash removal hanging rack structure for a combustion fireplace includes: a frame, the frame including a connecting rod and a suspension rod fixed to the connecting rod; a heat dissipation base plate, on which an upward-facing guide rod is fixed; a baffle fixed to the connecting rod, the baffle having a guide hole for the guide rod to pass through; a rigid first gasket is sleeved inside the guide rod, the first gasket lifting the baffle to create an airflow gap between the connecting rod and the base plate.

[0007] Preferably, the upper surface of the base plate is provided with a ring-shaped enclosure, and the frame is located inside the enclosure.

[0008] Preferably, the first gasket is made of stainless steel.

[0009] Preferably, a fireproof flexible pad is provided below the No. 1 pad.

[0010] Preferably, the fireproof flexible mat is a mica composite fireproof flexible mat.

[0011] In summary, this utility model has at least one of the following beneficial effects: (1) The lifting effect of the shim provides a space for airflow between the connecting rod and the base plate, so that the ash on the outside of the connecting rod can flow to the heat dissipation pipe through the space, making it less likely for the base plate on the outside of the connecting rod to accumulate dust, and the base plate can effectively transfer heat downward.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Example 1: A hanging rack structure for cleaning ash from a combustion fireplace, referring to... Figure 1 The system includes a frame 1, which includes connecting rods 11. The number of connecting rods 11 can be two or more. In this embodiment, there are two connecting rods 11, which are arranged in parallel.

[0017] Four suspension rods 12 are welded and fixed between the two connecting rods 11, and the springs for cleaning can be suspended on the suspension rods 12.

[0018] Push rods 8 are hinged to the two suspension rods 12 in the middle position via clamps. The push rods 8 extend downward into the furnace. When the flame is extinguished, the user can push the push rods 8 upward to clean the ash. Of course, other drive mechanisms can also be used to drive the push rods 8 to clean the ash. The drive of the push rods 8 is not a key design point and will not be described in detail.

[0019] Reference Figures 2-3 It also includes a base plate 2 for heat dissipation. The base plate 2 is a metal plate. When hot air flows above the base plate 2, the base plate 2 can transfer heat downwards. Fresh air flows below the base plate 2, so the base plate 2 can heat the fresh air.

[0020] The upper surface of the base plate 2 is provided with a fence 21. The fence 21 is a metal strip and is welded to the base plate 2. The fence 21 forms a rectangular structure, and the frame 1 is located inside the fence 21.

[0021] There is a gap between the connecting rod 11 and the edge of the adjacent enclosure 21. This gap is to prevent the connecting rod 11 from rubbing against the edge of the enclosure 21 during up and down movement, and also to ensure that the connecting rod 11 has sufficient operating space when installed inside the enclosure 21.

[0022] As can be seen, an upward-facing guide rod 31 is fixed on the base plate 2; the guide rod 31 is a vertical metal rod and is welded to the base plate 2. A baffle 4 is bent and fixed below the connecting rod 11. The baffle 4 has a guide hole 32 for the guide rod 31 to pass through. The guide hole 32 is an oval hole. The guide rod 31 is inserted into the guide hole 32. The short diameter of the guide hole 32 constrains the guide rod 31, thus limiting the left and right swing of the guide rod 31.

[0023] Reference Figure 3 and Figure 5 A rigid first washer 5 is fitted inside the guide rod 31. The first washer 5 is located between the base plate 2 and the baffle 4. Its purpose is to lift the baffle 4 when the frame 1 falls to a stop, thereby lifting the connecting rod 11 at the base plate 2, so that there is an airflow gap a between the connecting rod 11 and the base plate 2. The position of gap a is as follows: Figure 5 As shown.

[0024] The No. 1 gasket 5 is a stainless steel sheet, and the upper and lower surfaces of the stainless steel sheet are flat.

[0025] The function of shim 5 is to raise connecting rod 11; The stainless steel sheet also disperses the impact force and reduces local stress concentration. When the connecting rod 11 falls, it will hit the base plate 2. The impact force usually acts on the surface of the pad in the form of "point or line contact". The planar structure and uniform material of the stainless steel pad can quickly transform this "concentrated force" into "uniformly distributed force of surface contact", which greatly reduces the local stress intensity of the base plate 2 below.

[0026] In practical use, refer to Figure 2 Four rows of heat dissipation pipes are welded below the base plate 2. The first two rows are connected to the furnace and the last two rows are connected to the tail pipe. Therefore, the hot air in the furnace is discharged after passing through the four rows of heat dissipation pipes. During the circulation process, the hot air heats the four heat dissipation pipes. Fresh air flows under the base plate 2, and the heat dissipation pipes and the base plate 2 heat the fresh air. Reference Figure 5 A cover plate 7 is fixed above the base plate 2, forming a hot airflow conversion chamber. When the hot air flows in the conversion chamber, the hot airflow carries a large amount of ash, and some of the ash is discharged from the tailpipe along with the flow of hot air; Reference Figure 2 The ash between the connecting rod 11 and the enclosure 21 flows from the gap below the connecting rod 11 to the heat dissipation pipe for discharge, which reduces the accumulation of ash on the base plate 2 at this location, and the base plate 2 at this location can transfer heat energy to the fresh air below.

[0027] The installation position of the ash removal hanging rack structure in the fireplace is as follows: Figure 6 As indicated, cover plate 7 is located at the top of the fireplace, and the hot air flows upward to the conversion chamber for airflow circulation.

[0028] Example 2, an ash removal hanging rack structure for a combustion fireplace, differs from Example 1 in that, referring to... Figure 7 and Figure 8 A fire-resistant flexible pad 6 is provided below the first pad 5. The fire-resistant flexible pad 6 is placed below the first pad 5. In other embodiments, the fire-resistant flexible pad 6 and the first pad 5 can be bonded together with high-temperature resistant adhesive.

[0029] The fireproof flexible mat 6 is a mica composite fireproof flexible mat 6; the structure of the mica composite fireproof flexible mat 6 is: mica sheet + fiberglass cloth or silicone rubber. The mica sheet is the high-temperature resistant core, with a temperature resistance of 600-800℃.

[0030] When the mica composite fireproof flexible pad 6 is impacted, the impact damage to the base plate 2 is less than that of the rigid pad.

[0031] Therefore, a combination of soft and hard pads provides a better effect.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
