Description

Technical Field

[0001] The invention relates to a solid fuel heating stove, in particular to a rotating combined device heating stove which can burn biomass particles and clean coal fuel and is suitable for being installed on a heated brick bed. Background Art

[0002] Because the heating furnaces used for kang installation on the market lack the complete function of thermal efficiency regulation and conversion. As a result, it cannot adapt to the different smoke exhaust and air intake capabilities of different kang sizes, cannot ensure the normal combustion of fuel, and increase environmental pollution. Or in different combustion use periods such as high-temperature combustion heating and low-temperature night fire sealing, it is impossible to control the exhaust heat, select the kang surface temperature, and reduce fuel consumption by converting the heat exchange efficiency. Or in the slow fire period when the fire is sealed and turned into normal combustion, it is impossible to increase the kang suction force by reducing the heat exchange efficiency and increasing the smoke exhaust temperature to achieve rapid slow fire. For this reason, the applicant disclosed such a control heat exchange heating furnace in the 2023211067620 patent document: it has a hot water exchange pipe inside the water jacket flue and is connected to the upper and lower water jackets of the flue, and a control plate is provided on one side of the smoke exhaust port of the hot water exchange pipe, and a flow guard plate is provided on the side of the strip opening on the control plate, and an adjustable heat exchange and smoke exhaust channel can be formed between the flow guard plate and the hot water exchange pipe. By setting a flow guard plate on the side of the strip opening, when the control plate rotates from the flue opening state to the strip opening and the hot water exchange pipe in parallel, the control plate and the flow guard plate can effectively block the straight smoke exhaust in the adjacent hot water exchange pipe interval, so that the flue heat flow enters the heat exchange smoke exhaust channel and exchanges heat with the hot water exchange pipe. However, due to the large gap between the adjacent flow guard plates in the hot water exchange pipe interval (as shown in the above patent attachment), Figure 2 , Attachment Figure 4 As shown in the figure, the adjacent flow protection plate will divert part of the flue heat flow to the control plate. As a result, before the control plate rotates to the heat flow closed state, the heat flow will always leak out from the upper space of the control plate. The leaked hot air flow will compete for the flushing heat exchange air flow entering the heat exchange and smoke exhaust channel, resulting in the loss of the intermediate process of the thermal efficiency conversion of the control plate device, making it lack the continuity and integrity of the thermal efficiency conversion.

[0003] When the control plate rotates to the airflow closed state, the hot air flow in the direction of the control plate is easy to generate vortex airflow inside due to the structural dead angle between the control plate and the airflow protection plate. The vortex airflow is easy to interfere with the airflow entering the heat exchange and smoke exhaust channels on both sides of the airflow protection plate. Moreover, when the smoke exhaust capacity of the kang is small, the rising airflow in the furnace cannot be effectively divided into the heat exchange and smoke exhaust channels, which will further weaken its heat exchange and smoke exhaust capacity.

[0004] This patent adopts a double-layer structure in which a flow protection plate is set on one side of the control plate, which not only increases the difficulty of the process production, but also increases the structural weight and production cost of the control plate device.

[0005] Obviously, the overall area of ​​the inner wall plate of the water jacket flue is not less than the overall area of ​​the hot water exchange pipe. The control plate and the flow protection plate only constitute a heat exchange and smoke exhaust channel around the hot water exchange pipe, thereby improving the heat exchange efficiency of the hot water exchange pipe, but cannot simultaneously constitute a flushing heat exchange space with the inner wall plate of the water jacket flue to achieve synchronous flushing heat exchange, resulting in the inability to improve its flushing heat exchange capacity. Summary of the invention

[0006] In order to solve the above problems, the present invention proposes a method to strengthen the flushing heat exchange airflow and expand the flushing heat exchange space, so that the complete conversion of high and low thermal efficiency can be achieved at different use periods of various kangs.

[0007] The present invention discloses a rotating combined device heating furnace, comprising a water jacket furnace body and a water jacket flue interconnected therewith, the water jacket furnace body and the water jacket flue being provided with a water inlet and a water outlet, a plurality of hot water exchange pipes being provided inside the water jacket flue, a rotating combined device being provided on one side of the smoke outlet of the hot water exchange pipe, the rotating combined device comprising a plurality of U-shaped plates with heat exchange smoke outlets, a rotating shaft comprising the rotating combined device being fixedly connected to the U-shaped plate and being matched with the side axial hole of the water jacket flue, the U-shaped plate corresponding to the hot water exchange pipe, the U-shaped plate being able to rotate to form a longitudinal heat exchange space, and the mutual edges in the U-shaped plate being able to form a combined edge for hot gas diversion.

[0008] By setting a rotating assembly device inside the water jacket flue, during the process of the U-shaped plate rotating to form the heat exchange space of the heat exchange water pipe, the combination edge of the U-shaped plate will gradually divide the flue hot air flow from the low position to the overall surface of the heat exchange water pipe for flushing and heat exchange, realizing a complete conversion of high and low thermal efficiency. And significantly improve the heat exchange capacity throughout the process. Under various use conditions, the corresponding angles of the U-shaped plate and the heat exchange water pipe can be adjusted to make the best choice of combustion state and heat exchange state.

[0010] By setting a U-shaped plate and a fire guide plate in the rotating assembly device, and using the U-shaped plate and the fire guide plate to rotate with the hot water exchange pipe and the heat bearing plate to form a longitudinal heat exchange space, the flushing heat exchange area in the water jacket flue can be effectively expanded to improve the flushing heat exchange capacity. At the same time, the smoke exhaust interval between the side wall plate of the water jacket flue and the adjacent hot water exchange pipe is also expanded, and the control capacity of inefficient heat exchange and smoke exhaust is expanded. At least one hot water exchange pipe is set in the water jacket flue, which also optimizes the setting structure of the smallest furnace type.

[0011] As a further improvement of the present invention, the spacing between the water jacket flue side wall plate and the adjacent hot water exchange pipe does not have a setting space on one side of the U-shaped plate, and the hot water exchange pipe is set correspondingly with an incomplete U-shaped plate. The incomplete U-shaped plate has at least half the structure of the U-shaped plate. The incomplete U-shaped plate is fixedly connected to the rotating shaft. The incomplete U-shaped plate can rotate to form a longitudinal heat exchange space corresponding to the hot water exchange pipe. The mutual edges of the incomplete U-shaped plate and the U-shaped plate can form a combined edge for hot gas diversion. With this structure, the scope of application of different use conditions and setting conditions can be expanded.

With this structure, the heat exchange distance between the bottom of the U-shaped plate and the back-fire end of the hot water exchange pipe can be selected in time to realize the transition from normal flushing heat exchange of the hot water exchange pipe to efficient flushing heat exchange.

[0016] As a further improvement of the present invention, the closing piece outside the strip shaft hole has a convex shape at the position corresponding to the strip shaft hole.

DETAILED DESCRIPTION

[0028] Depend on Figure 1 , Figure 2 As shown in the embodiment of the present invention, a furnace plate 2 is provided on the top of the water jacket furnace body 1, and a fuel filling port is left on the furnace plate 2, which also serves as a cooking port. The fuel filling port can also be provided on one side of the furnace body. A single body or water jacket heat exchange plate 4 can be provided below the furnace plate 2, and a cooking port is provided on the heat exchange plate 4 and corresponds to the cooking port on the furnace plate 2. A furnace port cover 21 is provided on each cooking port to seal the heat of the furnace. Of course, the cross-sectional shape of the water jacket furnace body 1 can be square, rectangular or other suitable shapes. A furnace lining 14 is provided inside the water jacket furnace body 1, and a grate 3 is provided at the lower part thereof. An air inlet is provided on one side of the lower part of the grate 3. The ash cleaning hopper 13 provided on the air inlet can open or close the air inlet. A water jacket flue 5 is provided on one side of the water jacket furnace body 1, and the water jacket furnace body 1 is connected to the water jacket of the water jacket flue 5. The water inlet 11 provided on the water jacket furnace body 1 and the water outlet 12 provided on the water jacket flue 5 form a circulation loop with the heating system. The corresponding openings of the water jacket furnace body 1 and the water jacket flue 5 are flue fire inlets 16, and the other end of the corresponding flue fire inlet 16 is a smoke exhaust port 17. The water jacket furnace body 1 and the water jacket flue 5 are not limited to being integrally formed as a water jacket structure. Figure 1 As shown, it can obviously be a combination of a water jacket body and a single plate body. The upper wall plate of the water jacket flue 5 can be as follows Figure 1 As shown, the upper wall plate has an upward protrusion, but the upper wall plate can also be a flat plate without protrusions. A hot water exchange pipe 15 is arranged inside the water jacket flue 5, and the hot water exchange pipe 15 is connected with the upper and lower water jackets of the water jacket flue 5. The hot water exchange pipe 15 can be arranged in a forward and backward tilted manner in the water jacket flue 5, or can be arranged in a vertical shape. The cross-sectional shape of the hot water exchange pipe 15 can be circular, elliptical or other suitable shapes.

[0029] exist Figures 1 to 3In the first embodiment shown, a plurality of hot water exchange pipes 15 are arranged inside the water jacket flue 5, and the hot water exchange pipes 15 are arranged in a single row between the side wall plates of the water jacket flue 5. A rotating assembly device is arranged on one side of the smoke outlet 17 of the hot water exchange pipe 15, and the rotating assembly device includes a plurality of U-shaped plates 7, and the bottom of the U-shaped plate 7 has a heat exchange smoke outlet 9. The heat exchange smoke outlet 9 can be extended to both ends at its bottom, or can be intermittently arranged at its bottom. The rotating shaft 6 included in the rotating assembly device is fixedly connected to the U-shaped plate 7. The axial hole on the side wall plate of the water jacket flue 5 is adapted to the corresponding rotating shaft 6. The leading end of the rotating shaft 6 has a rotating positioning device to adjust the rotation positioning of the U-shaped plate 7 in the water jacket flue. The number of the U-shaped plates 7 is the same as that of the hot water exchange pipes 15 and they correspond to each other. The setting interval between the side wall plate of the water jacket flue 5 and the adjacent hot water exchange pipe 15 has a setting space that can accommodate one side of the U-shaped plate 7. The U-shaped plate can be rotated until the hot water exchange pipe 15 enters its interior. The inner wall plate of the U-shaped plate 7 forms the longitudinal heat exchange space 18 of the hot water exchange pipe 15. The hot water exchange pipe 15 may enter the interior of the U-shaped plate 7 as a whole, or may enter the interior of the U-shaped plate 7 partially as a whole. However, the hot water exchange pipe 15 entering the interior of the U-shaped plate 7 as a whole can strengthen the flushing heat exchange airflow at the fire-facing end of the hot water exchange pipe 15, increase the heat exchange stroke of the hot water exchange pipe 15, and improve the heat exchange efficiency. The shape of the U-shaped plate 7 is not limited to the shape of the English letter "U", but also includes other suitable shapes that can be rotated to form the longitudinal heat exchange space 18. The mutual edges in the plate constituting the longitudinal heat exchange space 18 can form a combined edge 8 for hot gas diversion. The combined edge 8 can be a connector of the mutual edges, or it can have a combined interval between the mutual edges. So that the structure is stable in the use environment. The radial direction of the rotating shaft 6 corresponds to the axial direction of the heat exchange water pipe 15 with a suitable interval. The rotating shaft 6 can be arranged at the lower end of the U-shaped plate 7 when the heat exchange smoke outlet 9 and the heat exchange water pipe 15 are parallel. However, the preferred mode is that the rotating shaft 6 and the heat exchange smoke outlet 9 are arranged crosswise. Figure 1 When the flue is in the open state as shown, the heat exchange smoke outlet 9 at the lower end of the U-shaped plate 7 can be rotated counterclockwise to include the corresponding back-fire end of the hot water exchange pipe 15, so as to increase the setting distance between the lower end of the U-shaped plate 7 and the rotating shaft 6, and then increase the height of the rotating shaft 6 from the lower wall plate of the water jacket flue 5 while keeping the radial distance between the rotating shaft 6 and the axial distance between the hot water exchange pipe 15 unchanged, thereby expanding the cleaning space between the rotating shaft 6 and the lower wall plate of the water jacket flue 5.

[0030] In the control of the rotating assembly device, the back extension end of the longitudinal heat exchange space 18 forming plate is provided with a fire collecting plate 36. The fire collecting plate has a sealing function that the airflow at the upper end of the flue flows outward from the upper port on the back of the longitudinal heat exchange space forming plate. When the fire collecting plates are connected to each other at their far fire ends and extend outward as a whole, they can rotate to form the transverse heat exchange space of the water jacket flue.

[0031] The rotating assembly works as follows: when the rotating assembly in the water jacket flue 5 rotates from the fire-blocking state to the Figure 1 , Figure 2 When the flue is shown to be in an open state, the hot air flow entering the flue will pass through the intervals between the multiple single-row hot water exchange pipes 15 and be discharged directly. Its higher exhaust temperature can improve the exhaust and air intake capabilities of the smaller suction kang, so that the fuel can enter normal combustion as soon as possible. When the U-shaped plate 7 rotates toward the side of the hot water exchange pipe 15, the U-shaped plate 7 first forms a longitudinal heat exchange space 18 at the lower end of the hot water exchange pipe 15, and its side combination edge 8 divides the high-temperature airflow in the flue into the formed longitudinal heat exchange space 18, forming the initial heat exchange airflow at the lower end of the hot water exchange pipe 15. As the upper end of the hot water exchange pipe 15 enters more of the U-shaped plate 7, the flushing heat exchange capacity of the hot water exchange pipe 15 will be simultaneously improved. When the hot water exchange pipe 15 fully enters the interior of the U-shaped plate 7 to form a complete longitudinal heat exchange space 18, the upper wall plate of the water jacket flue 5 also constitutes a transverse heat exchange space 38 at the same time. The high-temperature flue gas at the flue inlet 16 will be divided as a whole to form a synchronous flushing heat exchange airflow, thereby expanding the flushing heat exchange area, increasing the exhaust air inlet airflow, and significantly improving the heat exchange capacity.

[0032] Figure 4 , Figure 5 The difference between the second embodiment shown and the first embodiment is that one or more heat exchange water pipes 15 are arranged inside the water jacket flue, and the side wall plate of the water jacket flue 5 has a water jacket body heat bearing plate 34. The rotating assembly device includes one or more U-shaped plates 7 corresponding to the heat exchange water pipes 15, and the rotating assembly device also includes a fire guide plate 35 outside the U-shaped plate 7 and echoing the heat bearing plate 34, and the U-shaped plate 7 and the fire guide plate 35 are fixedly connected to the rotating shaft 6. Preferably, the fire guide plate 35 has a bending angle. The inner side wall plate of the fire guide plate 35 can rotate synchronously to form the longitudinal heat exchange space 18 of the heat bearing plate 34. The mutual edges in the fire guide plate 35 of the U-shaped plate 7 can form a combined edge 8 for hot gas diversion. Obviously, the combined edge 8 can divide the flue heat flow to the U-shaped plate 7 and the fire guide plate 35. The flue heat flow squeezed by the fire guide plate 35 flushes and exchanges heat in the narrow and long area of ​​the longitudinal heat exchange space 18. The flushing heat exchange area in the water jacket flue 5 is enlarged, and the flue smoke exhaust ventilation volume under the flushing heat exchange state is enhanced. The setting of the fire guide plate 35 also enlarges the smoke exhaust interval between the side wall plate of the water jacket flue 5 and the adjacent hot water exchange pipe 15, and expands the control range of inefficient heat exchange and smoke exhaust.

[0033] The improved heat exchange smoke outlet 9 is composed of a reverse arc panel, which is transitioned with the U-shaped plate surface, so as to reduce air flow resistance and improve heat exchange and smoke exhaust capacity.

[0034] Figures 6 to 9The third embodiment shown is different from the first embodiment only in that the interval between the side wall plate of the water jacket flue 5 and the adjacent hot water exchange pipe 15 does not have a setting space that can accommodate one side of the U-shaped plate 7, and the hot water exchange pipe 15 is set correspondingly with an incomplete U-shaped plate 33. The incomplete U-shaped plate 33 has at least half the structure of the U-shaped plate 7. The incomplete U-shaped plate 33 is fixedly connected to the rotating shaft 6. The incomplete U-shaped plate 33 can rotate to form a longitudinal heat exchange space 18 at the corresponding part of the hot water exchange pipe 15. The mutual edges of the incomplete U-shaped plate 33 and the U-shaped plate 7 can form a combined edge 8 for hot gas diversion. The U-shaped plate 7 adopts a preferred structure in which the side edges are separated outward, which can increase the airflow scouring heat exchange angle and enhance the heat exchange effect.

[0035] The shaft holes on the wall plates on both sides of the water jacket flue 5 are strip-shaped shaft holes 19, and the rotating shaft 6 can reciprocate in the strip-shaped shaft holes 19. In order to realize the movement and closure of the strip-shaped shaft hole 19, a closing piece 23 is provided on the rotating shaft 6, and the shaft hole on the closing piece 23 is adapted to the rotating shaft 6. A spring 24 is provided on the closing piece, and a fixing ring 25 is provided on the other end of the spring 24. The fixing ring 25 is positioned on the rotating shaft 6 through a pin 26. The spring 24 can be provided on both sides of the flue, but the spring 24 is provided on the closing piece 23 on one side of the flue, that is, the spring 24 can be used to pull the opposite closing piece 23 and the wall plate where the strip-shaped shaft hole 19 is located to form a corresponding pressure through the reverse force of the spring 24 on the rotating shaft 6. In order to avoid condensation of soot at the closing piece 23 corresponding to the strip-shaped shaft hole 19 during movement, the closing piece 23 is convex at the position corresponding to the strip-shaped shaft hole 19 when moving. The corresponding concave surface of the outer convex shape can accommodate the condensed soot in the strip-shaped shaft hole 19, so that the outer plane of the closing piece 23 and the wall plate where the strip-shaped shaft hole 19 is located can be seamlessly closed.

[0036] In order to facilitate the adjustment of the movement of the rotating shaft 6 in the strip shaft hole 19, a rotating rod 20 is arranged outside the flue, and a fork-shaped piece 22 is arranged at both ends of the rotating rod 20, and the rotating shaft 6 can be flexibly placed in the fork of the fork-shaped piece 22. Since the rotating rod 20 and the rotating shaft 6 are arranged in the same direction, the fork-shaped pieces 22 at both ends of the rotating rod 20 form a same angle and radius shift with the rotating shaft 6 at both ends, so that the rotating shaft 6 can move synchronously in the strip shaft hole 19. The outer end of the rotating rod 20 is provided with a moving positioning device, and the preferred arrangement mode is that the rotating positioning device at the lead-out end of the rotating shaft 6 and the moving positioning device at the outer end of the rotating rod 20 are arranged on both sides of the flue, so that the corresponding angle between the U-shaped plate 7 and the hot water exchange pipe 15 and the appropriate distance between the heat exchange smoke outlet 9 and the hot water exchange pipe 15 can be adjusted in both directions. When the kang has a large suction force, the rotating shaft 6 can drive the heat exchange smoke outlet 9 to move closer to the back-fire end of the hot water exchange pipe 15, which can increase the heat exchange stroke of the hot water exchange pipe 15 in the U-shaped plate 7, enhance the flushing heat exchange intensity of the fire-facing surface of the hot water exchange pipe 15, compress the heat exchange interval of the back-fire surface of the hot water exchange pipe 15, and further enhance the heat exchange efficiency.
