Abstract
Description
Technical Field
[0001] This utility model relates to the field of submersible pump technology, and in particular to an energy-saving hot air circulation heating furnace suitable for greenhouses. Background Technology
[0002] The energy-saving hot air circulation heater in the greenhouse improves the combustion efficiency of honeycomb briquettes, which can raise the temperature inside the greenhouse in a short time. It is suitable for dealing with sudden cold waves. Compared with electric heaters or gas equipment, it is inexpensive, suitable for small farmers, widely adaptable, and does not require electricity support, so it can be used in remote areas with power shortages.
[0003] Existing equipment typically consists of a shell, support frame, base, and placement trough. The base and shell work together to support the support frame, allowing it to support the square honeycomb briquettes and ensure stable combustion. The placement trough holds the igniter and honeycomb briquettes, enabling them to burn inside the shell and release heat, thus raising the temperature inside the greenhouse.
[0004] However, during use, the ash produced after the honeycomb briquettes burn accumulates inside the outer shell. This means that after each briquette burns, it is necessary to stop placing new briquettes and spend a lot of time cleaning up the ash before continuing to burn briquettes to provide heat to the greenhouse. This causes a break in the heat supply, resulting in reduced efficiency and poor heating effect. To address this issue, an energy-saving hot air circulation heater suitable for greenhouses is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an energy-saving hot air circulation heating furnace suitable for greenhouses, aiming to improve the problem in the existing technology where the ash produced after the burning of honeycomb briquettes requires a lot of time to clean up, resulting in a break in the heating supply and a reduction in heating efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving hot air circulating heater suitable for greenhouses includes an outer shell, a placement groove in the middle of the outer shell, a crossbar fixedly connected to the middle of the outer shell, and an ash collection component installed in the middle of the outer shell. The dust collection assembly includes a grid, which is fixedly connected to the middle of the outer shell. A dust collection box is slidably connected to the middle of the outer shell. A limit hole is opened on the outside of the dust collection box. A limit block is fixedly connected to the outside of the outer shell. A limit rod is slidably connected to the middle of the limit block. The limit rod and the limit hole are engaged with each other. A spring is provided inside the limit block. As a further description of the above technical solution: The outer side of the outer casing has an upper air inlet, the outer side of the outer casing has a lower air inlet, and the outer casing has symmetrical heat dissipation holes on both sides. As a further description of the above technical solution: A connecting block is rotatably connected to the middle of the outer shell, and a fire door is fixedly connected to the outer side of the connecting block; As a further description of the above technical solution: A heat-insulating handle is fixedly connected to the outside of the fire door, and a fixing hole is provided on the outside of the fire door. As a further description of the above technical solution: A fixing block is fixedly connected to the outer side of the outer shell, and a fixing rod is slidably connected to the middle of the fixing block. The fixing rod and the fixing hole are engaged with each other, and a spring is provided inside the fixing block. As a further description of the above technical solution: A fixing frame is fixedly connected to the inner side of the outer casing, and a smoke exhaust pipe is fixedly connected to the middle part of the outer casing; As a further description of the above technical solution: A support column is fixedly connected to the bottom of the outer shell, and an anti-slip block is fixedly connected to the bottom of the support column.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the outer shell provides support for the grid and the ash collection box, and the limiting rod and the limiting hole cooperate to provide a fixing effect for the ash collection box, so that it will not shift during operation. This allows the ash produced after the honeycomb briquette is burned to reach the inside of the ash collection box through the grid, thereby achieving rapid collection of ash and making subsequent ash cleaning more convenient. This also prevents the heating from being interrupted and improves the heating efficiency.
[0008] 2. In this utility model, the external natural wind enters the interior of the shell through the upper and lower air inlets, thereby assisting the combustion of the square honeycomb briquettes, enabling them to burn fully, improving their combustion efficiency, and allowing them to release more heat, thus providing more heat supply for the greenhouse.

[0011] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figure 1 and Figure 4This utility model provides an embodiment of an energy-saving hot air circulating heater suitable for greenhouses, comprising an outer shell 1, a placement groove 12 in the middle of the outer shell 1, a crossbar 11 fixedly connected to the middle of the outer shell 1, and an ash collection component installed in the middle of the outer shell 1. The placement groove 12 allows for the storage of igniting materials, facilitating the ignition of square honeycomb briquettes. The heat generated by the combustion of these igniting materials increases the stability of the greenhouse interior. The outer shell 1 provides support for the crossbar 11, ensuring stable operation and better support for the square honeycomb briquettes, preventing displacement. The outer shell 1 also provides support for the ash collection component, enabling stable operation and collection of ash produced after the honeycomb briquettes burn, facilitating subsequent ash processing. The ash collection component includes a grid 13, which is fixedly connected to the middle of the outer shell 1. An ash collection box 14 is slidably connected to the middle of the outer shell 1, providing support for the grid 13 and ensuring its stability. In operation, the ash produced after the burning of honeycomb briquettes passes through the grid 13 and reaches the ash collection box 14, thereby achieving ash collection. The ash collection box 14 has a limiting hole 15 on its outer side, and a limiting block 17 is fixedly connected to the outer side of the outer shell 1. A limiting rod 16 is slidably connected to the middle of the limiting block 17. The limiting rod 16 and the limiting hole 15 are engaged with each other. A spring 18 is provided inside the limiting block 17, and the outer shell 1 provides support for the limiting block 17, enabling it to operate stably. This allows it to better support the limiting rod 16, so that the limiting rod 16 can cooperate with the limiting hole 15 to lock the ash collection box 14, preventing displacement of the ash collection box 14 during operation and making the disassembly of the ash collection box 14 more convenient. The spring 18 allows the limiting rod 16 to reset after movement. Through the cooperation between the various structures of the ash collection component, the ash produced after the burning of honeycomb briquettes can be collected, so that the next burning of honeycomb briquettes will not be affected, and the cleaning of ash is more convenient.
[0013] Reference Figure 1 Figure 2 and Figure 3 , Figure 5The outer shell 1 has an upper air inlet 20 and a lower air inlet 23 on its outer side. Symmetrical heat dissipation holes 9 are located on both sides of the outer shell 1. The upper and lower air inlets 20 and 23 work together to allow natural airflow into the outer shell 1, ensuring complete combustion of the honeycomb briquettes and improving combustion and heat release efficiency. The heat dissipation holes 9 allow the heat generated during combustion to dissipate outwards, increasing the stability of the greenhouse interior. A connecting block 2 is rotatably connected to the middle of the outer shell 1. A fire door 3 is fixedly connected to the outer side of the connecting block 2, and a heat-insulating handle 4 is fixedly connected to the outer side of the fire door 3. The connecting block 2 allows the fire door 3 to connect to the outer shell 1, enabling the fire door 3 to seal the outer shell 1 and prevent flames from splashing out during combustion, thus avoiding danger. A fixing hole 5 is located on the outer side of the fire door 3, and a fixing block 7 is fixedly connected to the outer side of the outer shell 1. A sliding connection is made in the middle of the fixing block 7. The fixing rod 6 and the fixing hole 5 are interlocked. The fixing block 7 is equipped with a spring 8 inside. The outer shell 1 provides support for the fixing block 7 so that it can operate stably, thereby providing better support for the fixing rod 6. The fixing rod 6 can cooperate with the fixing hole 5 to achieve the locking effect of the fire door 3, so that the fire door 3 will not be displaced during operation. The spring 8 can make the fixing rod 6 return to its original position after movement. The inner side of the outer shell 1 is fixedly connected to the fixing frame 10, and the middle of the outer shell 1 is fixedly connected to the smoke pipe 19. The fixing frame 10 provides support for the honeycomb briquettes, so that the honeycomb briquettes can burn stably. The smoke generated by the burning honeycomb briquettes can be discharged from the inside of the outer shell 1 through the smoke pipe 19. The bottom of the outer shell 1 is fixedly connected to the support column 21, and the bottom of the support column 21 is fixedly connected to the anti-slip block 22. The support column 21 and the anti-slip block 22 cooperate with each other to provide stable support for the outer shell 1 and to ensure stable operation of the outer shell 1.
[0014] Working principle: In use, by pulling the fixing rod 6, it moves within the fixing block 7, causing the fixing rod 6 to disengage from the fixing hole 5, thereby releasing the lock on the fire door 3. At this time, pulling the heat insulation handle 4 moves the fire door 3, causing the connecting block 2 to rotate along the outer shell 1, thus opening the fire door 3 and exposing the placement cavity inside the outer shell 1. The igniter is placed in the placement slot 12, and then square honeycomb briquettes are placed on the fixing frame 10. After placing the outer side, the igniter is lit, the fire door 3 is closed, and at the same time, the fixing rod 6 is released and pushed back to its original position by the spring 8, locking the fire door 3. At this time, the outside natural air enters the interior of the outer shell 1 through the upper air inlet 20 and the lower air inlet 23, thus making the honeycomb briquettes inside the outer shell 1 burn more completely.
[0015] At this time, the heat generated by the burning of the honeycomb briquette is discharged through the heat dissipation hole 9, and the flue gas generated by the combustion is discharged through the exhaust pipe 19. When the honeycomb briquette is completely burned, it is necessary to clean its ash. By pulling the limiting rod 16, it moves in the limiting block 17, so that the limiting rod 16 is disengaged from the limiting hole 15, thereby releasing the lock on the ash collection box 14. Pulling the handle moves the ash collection box 14, so that it is disengaged from the outer shell 1. At this time, the ash inside can be cleaned. After cleaning, the ash collection box 14 is pushed into the middle of the outer shell 1, the limiting rod 16 is released, and the spring 18 pushes it to reset, so that it is engaged with the limiting hole 15, thereby locking the ash collection box 14.
[0016] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
