Abstract
Description
Technical Field
[0001] This invention belongs to the field of combustion furnace technology, and particularly relates to a tilting beaker. Background Technology
[0002] Combustion-fired heaters are common and frequently used heating devices, especially in high-latitude regions and cold winter climates where demand is high. Currently, existing heaters are classified by energy source, including electric heaters, coal heaters, and water heaters, which respectively use electric power, combustion power, and hot water for heating. Small electric heating devices, such as mini electric heaters, fan heaters, and oil-filled radiators, are commonly used. However, due to power limitations, their heat output is relatively limited, resulting in poor actual heating performance. Water heaters are typically designed as part of building-integrated heating systems and are not suitable as a supplementary heating method.
[0003] With the development of new and clean fuels such as anthracite, solid-fuel combustion heaters have once again come into focus. Combustion heating is stable and provides a large amount of heat, and its cost is lower than that of electric heating, thus gaining increasing acceptance. However, current heaters have some significant drawbacks. For example, the ash produced by solid fuels requires periodic emptying and cleaning, which is cumbersome. Untimely ash removal can easily lead to dust pollution and even the safety hazard of dust explosions. Therefore, the ash removal process for current solid-fuel combustion heaters is crucial for maintaining their normal operation, reducing environmental pollution, and improving safety.
[0004] Currently, most solid-fuel combustion heaters use built-in ash collection tanks to collect ash, or some have a transfer beaker, also known as a tilting beaker, which is fixed by a shaft and can be used to temporarily store combustion ash, effectively preventing the continuous and large-scale accumulation of ash and the resulting dust explosion hazard. Ash is collected quantitatively or periodically, transferred and cooled, and then poured into a larger ash tank for emptying. However, the transfer process generally requires manual control, is cumbersome, and cannot be automated. Therefore, even semi-indoor solid-fuel combustion heaters with excellent heating performance cannot automatically guarantee their safety, limiting their application. Furthermore, the large amount of heat from combustion ash is difficult to dissipate, also creating a dust explosion hazard.
[0005] Therefore, it is of great significance to develop a tilting beaker that can automatically transfer combustion ash and enhance the collection and cooling of combustion ash. Summary of the Invention
[0006] To address the problems of existing inverted beakers, such as requiring manual operation, cumbersome process, low automation, high combustion ash temperature, and certain safety hazards when unattended, this invention provides an inverted beaker.
[0007] The main objective of this invention is:
[0008] 1. To achieve automated transfer of combustion ash from a tilting beaker;
[0009] II. It has a good transfer effect;
[0010] Third, it can effectively utilize the temperature of combustion ash and reduce safety hazards;

[0044] Example
[0045] One such Figure 1 The tilting beaker 10 shown is used for the pre-collection and pouring of solid fuel combustion ash in the solid fuel combustion furnace 20. When used in the solid fuel combustion furnace 20, it can form an ash-cleaning advantage, avoiding the defects of traditional ash-cleaning processes that require machine shutdown. It also avoids the problem of the traditional fixed beaker pouring process requiring manual operation and being relatively cumbersome when the beaker and ash tank 22 are used together. In addition, when there is a large amount of soot in the ash tank 22, the newly fallen high-temperature or even sparking combustion ash particles pose a safety hazard of secondary ignition of ash, causing deflagration or even dust explosion. Therefore, the current main development direction of solid fuel combustion furnace 20 is to adopt a two-stage collection of combustion ash to avoid direct contact between high-temperature ash and a large amount of dust.
[0046] The inverted beaker 10 specifically includes:
[0047] Mounting base 100, reverse motor 200, drive shaft, beaker assembly 400, induction assembly; beaker assembly 400 is used for ash collection.
[0048] The reverse motor 200 is a commercially available, programmable single-axis motor; the WT-85 model is used in this embodiment.
[0049] The mounting base 100 is used to install and fix the overall tilting beaker 10 in conjunction with the internal structure of the solid fuel combustion furnace 20. It is provided with a number of mounting holes 101, and is installed and fixed by rivets or screws and nuts. Since it usually operates under high temperature conditions and may need to bear a large weight, the firmness is not good by means of adhesive.
[0050] The reverse motor 200 and the beaker assembly 400 are located on opposite sides of the mounting base 100. The rotating shaft 300 is connected to the drive shaft of the reverse motor 200 and passes through the mounting base 100 to be fixedly connected to the beaker assembly 400.
[0051] Specifically, the beaker assembly 400 includes a beaker body 401 and a beaker base 402. The bottom of the beaker is provided with a pin hole and is rotatably hinged to the beaker body 401. The beaker body 401 is open at both the top and bottom, and the lower opening is movably closed by the beaker base 402. The two together form a beaker-like structure that can be opened and closed at the bottom and is open at the top, which is used to receive combustion ash.
[0052] The cup body 401 is fixed by a connecting arm 102 extending from the mounting base 100. One end of the rotating shaft 300 is fixed to the drive shaft of the reverse motor 200, and the other end extends into the cup body 401. A paddle 301 is provided on its outer circumference. A connecting seat 4021 is provided on the upper surface of the cup seat 402. The paddle 301 and the connecting seat 4021 are hinged. The reverse motor 200 can drive the rotating shaft 300 to rotate. The rotating shaft 300 drives the cup seat 402 to rotate relative to the cup body 401 through the paddle 301. The reverse motor 200 drives the cup seat 402 to close at the lower end of the cup body 401 through the rotating shaft 300, thus sealing the lower end of the cup body 401. The load power of the reverse motor 200 is set so that after a certain amount of ash is collected in the beaker assembly 400, the cup seat 402 opens and releases the ash downward.
[0053] The sensing component includes a sensing ring 302 sleeved on the rotating shaft 300, a limiting ring 303 sleeved on the outside of the sensing ring 302, and a limiting sensor 500 installed on the mounting base 100 or the inner wall of the combustion furnace. The optimal position of the limiting sensor 500 is in the horizontal direction of the sensing ring 302 to ensure that a large gap can be formed between it and the cup body 401, thereby avoiding and reducing ash contamination. The sensing ring 302 is fixed to the rotating shaft 300 and rotates in the same way as the rotating shaft 300. A plurality of sensing plates 3021 are provided on the outer periphery of the sensing ring 302.
[0054] The sensing ring 302 is also fitted with a limiting ring 303 with a sensing notch 3031 on the outside. The limiting ring 303 is fixedly connected to the mounting base 100 and covers the outer periphery of the sensing ring 302. The sensing notch 3031 is located on the side of the sensing ring 302 facing the limiting sensor 500.
[0055] The limit sensor 500 is electrically connected to the reverse motor 200;
[0056] When the limit sensor 500 senses the rotation of the rotating shaft 300, it sends an electrical signal to the reverse motor 200, which in turn drives the rotating shaft 300 to rotate, thereby causing the cup holder 402 to reset.
[0057] Specifically, such as Figure 4As shown, the tilting beaker 10 is installed in the solid fuel combustion furnace 20. The tilting beaker 10 is mounted entirely on the inner wall panel of the solid fuel combustion furnace 20 via the mounting base 100, and is positioned directly above the ash collection trough 22, the main ash-collecting structure of the combustion furnace. This allows for easy and quick ash disposal when the beaker is tilted. The ash discharge pipe 21 of the combustion assembly inside the solid fuel combustion furnace 20 extends directly above the tilting beaker 10 and the ash collection trough 22. The soot generated during the combustion process of the combustion assembly is first discharged through the ash discharge pipe 21. The ash falls into the tilting beaker 10. After a certain amount of ash is collected, the cup holder 402 opens to allow the ash to fall into the ash collection tank 22. The reverse motor 200 is used to reset the cup holder 402, which can achieve automatic ash removal of the beaker assembly 400 without manual operation. Manual operation only requires periodically removing the ash collection tank 22 and emptying it, which greatly improves the automation level of the combustion furnace. Compared with the conventional solid fuel combustion furnace 20, the volume of the ash collection tank 22 can be further increased to extend the cleaning cycle.
[0058] In addition, such as Figure 2 As shown, the cup holder 402 is provided with a closed water tank 4022, and the closed water tank 4022 is provided with a water inlet 40221. The water inlet 40221 is connected to a water supply pipe, and water is supplied to the water tank 4022 through the water supply pipe.
[0059] The enclosed water tank 4022 is equipped with a float seal 40222. Under the action of buoyancy, the float seal 40222 moves up and down along the track 40223, sealing the water inlet 40221 to control the upper limit of water volume in the water tank 4022. The base, as... Figure 1 and Figure 3 The diagram shows a tower-shaped structure 4023 inserted into the side wall of the cup body 401. The tower-shaped structure 4023 has an air outlet 40231 on the side facing the inside of the cup body 401. The air outlet 40231 is connected to the water tank 4022 through a channel 40232. The position of the connection between the channel 40232 and the water tank 4022 is higher than the height of the water inlet 40221, which can effectively prevent a large amount of water from entering the channel 40232.
[0060] The above structure allows a certain amount of water to be stored in the water tank 4022. In actual use, the combustion ash usually carries a lot of heat, so the beaker assembly 400 is also in a state of long-term high temperature. This state can heat the water in the water tank 4022 and generate steam. The steam is discharged into the cup body 401 through the channel 40232 and the vent 40231, which can wet the combustion ash. After being wetted, the combustion ash increases in weight and forms larger particles that fall into the beaker assembly 400, which can effectively reduce dust and improve the cleanliness of the inside of the combustion furnace.
[0061] Furthermore, to prevent clogging of the duct 40232, dust from entering the duct 40232, and to increase the actual vapor pressure, the following measures are implemented: Figure 3 The projectile seat 4024 shown is disposed in the channel 40232 and is in sealing contact with the wall of the channel 40232 to achieve a sealing setting. Its lower end is a seat bottom with an inverted conical cavity 40241 and a through hole at the tip of the cavity, and its upper end is an annular limiting head 40242. A sealing bead 40243 is provided inside the projectile seat 4024. The sealing bead 40243 falls down under the action of gravity to block the through hole of the seat bottom, so as to provide a movable seal for the projectile seat 4024 and the channel 40232.
[0062] After steam is generated and reaches a high vapor pressure in the water tank 4022, the steam pushes the sealing bead 40243 to contact the seal and enters the cup body 401 through the spring seat 4024 and the channel 40232, wetting and settling the combustion ash. At this time, it can ensure that the channel 40232 always maintains a high vapor pressure, which is a positive pressure environment relative to the cup body 401 environment, thus preventing dust from entering the channel 40232. When the vapor pressure drops, the spring seat 4024 seals, which can also effectively prevent dust from entering the water tank 4022 and making it difficult to clean. In addition, the channel 40232 is provided with a dustproof net 40233 at the opening on the side wall of the tower-shaped structure 4023, which can further prevent dust from entering the channel 40232 and improve the use effect.
