Description

Technical Field

[0001] The invention belongs to the technical field of solid treatment, and in particular relates to a solid incinerator. Background Art

[0002] Solid incineration treatment has been widely used in the field of solid treatment as a means of effectively reducing the volume and amount of solid waste. Generally, solid incinerators put solids into the combustion chamber for high-temperature incineration, thereby decomposing or gasifying most of the organic components to achieve harmless, reduced and resource-based solid treatment. However, there are still some problems that need to be solved in the actual use of solid incinerators in the prior art.

[0003] In the existing solid incineration process, due to the relatively single feeding method, the input of solids is often uneven, resulting in incomplete combustion of solids in some areas of the furnace, which in turn affects the overall incineration efficiency. In addition, if the solids are not fully loosened and stirred during the combustion process, it is difficult for the internal oxygen to evenly enter the solid accumulation layer, which limits the full combustion of the solids. At the same time, some solids generated during the incineration process may adhere to the inner wall of the furnace body, making it difficult to clean, affecting the service life and continuous operation of the furnace body. In addition, when the hot air generated by the solids during the incineration process cannot effectively penetrate and preheat and dry the upper layer of solids that have not yet been burned, the overall combustion efficiency and treatment effect still need to be improved.

[0004] In summary, existing solid incinerators face problems such as uneven feeding, incomplete combustion, easy adhesion of solids, difficulty in effective loosening, and insufficient preheating in actual use. These problems not only affect the processing efficiency and environmental benefits of solid incineration, but also increase the operating cost of the system. Therefore, there is an urgent need for a solid incinerator that can improve the feeding method, increase the solid looseness, optimize the combustion process, and enhance the preheating effect to meet the needs of actual use. Summary of the invention

[0013] Furthermore, a top ring and a support ring are provided at the bottom of the gear ring;

[0014] A ball bearing is arranged between the top ring and the support ring;

[0015] The upper end surface of the support ring is provided with a ball groove for storing balls;

[0016] A first mounting plate is fixedly connected to the bottom of the first motor, and the first mounting plate is connected to the inner side wall of the furnace body.

[0017] Furthermore, the top end of the turntable is fixedly connected with support arms at equal intervals around the central axis of the turntable, and the top end of the support arm is connected to the lower end surface of the support ring.

[0018] Furthermore, the stirring assembly includes a grate ring, the number of which is set to be multiple, and the diameters of the multiple grate rings are proportionally reduced;

[0019] A driving shaft is provided at the bottom center of the grate ring;

[0020] A first driven gear is sleeved on the bottom of the driving shaft;

[0021] A second motor is arranged at the bottom of the driving shaft, and an output end of the second motor is sleeved with a second driving gear meshing with the first driven gear. A second mounting plate is fixedly connected to the bottom of the second motor, and one end of the second mounting plate is connected to the support arm.

[0022] Furthermore, the furnace body includes a water-cooled wall, a refractory ring is arranged on the top of the water-cooled wall, an insulation ring is sleeved on the outside of the refractory ring, a furnace top cover is fixedly connected to the top of the refractory ring, and a smoke exhaust pipe is connected to the top of the furnace top cover.

[0023] Furthermore, the material loosening mechanism comprises a second cylinder installed on the outer side of the furnace body, and a material loosening rod is connected to the telescopic end of the second cylinder, and the material loosening rod extends into the interior of the furnace body.

[0024] Furthermore, the feeding mechanism includes a pushing tube fixedly connected to the furnace body, the upper end surface of the pushing tube is provided with a feeding tube for feeding solids, and one end of the pushing tube is fixedly connected to a first cylinder, the telescopic end of the first cylinder is connected to a pushing plate, and the pushing plate is located in the pushing tube;

[0025] The outer side surface of the push tube is provided with a heat insulation layer.

[0026] Furthermore, a connecting plate is fixedly connected to the bottom of the column;

[0027] A bottom plate is arranged at the bottom of the furnace body, the connecting plate is connected to the bottom plate, and a first through groove is penetrated through the upper end surface of the bottom plate.

[0028] Furthermore, second through grooves are evenly opened on the furnace bottom plate.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] By improving the feeding method, the solids to be incinerated can be fed into the furnace body in an orderly and uniform manner along the feeding pipe and the pushing pipe, thereby avoiding the problem of incomplete combustion in some areas caused by uneven feeding in the prior art. The push plate driven by the first cylinder in the pushing pipe can stably and continuously push the solids into the furnace body, making the solid layer distribution more reasonable. When the solids are in a suitable position, the loosening mechanism arranged on the outside of the furnace body is used to loosen the solids above, so that the originally dense solid accumulation structure becomes loose, which is conducive to the smooth entry of oxygen into the solids, and fundamentally solves the problems of insufficient oxygen and incomplete combustion during the solid combustion process.

[0031] By setting up a stirring assembly inside the furnace body and using multiple grate rings to stir and turn the layers, the solids are constantly disturbed and redistributed during the combustion process. With the multi-layer, decreasing diameter grate ring design, a good ventilation gap can be formed in each layer of solids, making the hot air flow smoother, thereby effectively improving the problem of uneven air penetration in the solid accumulation layer. The continuous operation of the stirring assembly can not only improve the combustion efficiency of the solids, but also reduce the cleaning difficulties and equipment losses caused by the solids adhering to the inner wall of the furnace body, thereby optimizing the stability of the furnace body and extending the life of the equipment.

[0032] By loosening the upper solid layer inside the furnace, the hot air can more easily penetrate the solid layer on the top of the grate ring, preheating and drying the unburned upper solid in advance. This preheating makes it easier for the solid to reach a high temperature when entering the actual combustion stage, thereby reducing the heating time, improving the overall combustion efficiency, and effectively reducing the probability of incomplete combustion and the generation of harmful gases.

[0033] By arranging the furnace chassis, support ring, ball bearing and other components in a coordinated manner in the structural design, the transmission resistance and mechanical vibration are reduced, making the grate ring and stirring assembly more stable and reliable during operation. Driven by the first motor and the second motor, the power is smoothly transmitted through reasonable gear meshing and support structure, which not only reduces energy consumption, but also provides reliable power support for continuous and long-term high-temperature combustion.

[0034] Through slots are set on the furnace chassis, bottom plate and corresponding components to allow the ash and slag formed by combustion to fall and be discharged in time, thus avoiding poor ventilation and subsequent cleaning difficulties caused by the accumulation of slag at the bottom. This optimized design enables the entire incineration device to achieve efficient combustion while greatly reducing the complexity of cleaning and maintenance, helping to maintain the continuous and stable working state of the equipment and improving the convenience of operation.

[0075] The working principle of the present invention is:

[0076] When in use, the solid to be incinerated is put into the feeding pipe 62 through the open end of the feeding pipe 62, and the solid entering the feeding pipe 62 will fall into the pushing pipe 61 along the feeding pipe 62.

[0077] Driven by the second motor 42 and in cooperation with the second driving gear 422 and the first driven gear 431, the grate ring 41 is driven to rotate. As the grate ring 41 rotates, the solids falling on the grate ring 41 will be loosened, so that during the combustion of the solids, it is easier for oxygen to enter the gaps in the solids, thereby improving the combustion efficiency of the solids.

[0078] Driven by the first motor 35 and in cooperation with the first driving gear 351 and the gear ring 33, the furnace bottom plate 34 located on the top of the gear ring 33 is driven to rotate, thereby driving the protective cylinder 5 to rotate synchronously. During the rotation process, the protective cylinder 5 can stir the solid attached to the inner wall of the water-cooled wall 11 to prevent the solid from adhering to the inner wall of the water-cooled wall 11 during the combustion process.

[0079] During the rotation process, the furnace bottom plate 34 is always in a rotating state, and the grate ring 41 rotates indirectly;

[0080] During the solid incineration process, the second cylinder 71 drives the loosening rod 72 at its telescopic end to perform telescopic movement. As the loosening rod 72 is extended and retracted, the solid on the grate ring 41 can be loosened, so that the hot air generated by the solid combustion can pass through the solid on the top of the grate ring 41, preheating and drying the unburned solid on the top, so as to facilitate the subsequent combustion of the solid;

[0081] The smoke generated by the combustion will be discharged through the smoke exhaust pipe 141 provided on the top of the furnace top cover 14;

[0082] The slag produced during the combustion process will pass through the grate ring 41 and the second through groove 341 , fall onto the bottom plate 15 , and be discharged through the first through groove 151 .

[0083] The above is only a preferred embodiment of the present invention.
