Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding device technology, and in particular to a dual-feed material level control device. Background Technology
[0002] Controlling and ensuring the material level inside the gasifier is crucial for continuous and safe production. Currently, most gasifiers in China require a stable and high-level pressurized layer to maintain the four reaction layers within the furnace: the drying layer, the pyrolysis layer, the reduction layer, and the oxidation layer. Balanced feeding and uniform distribution of raw materials are also prerequisites for stable oxidation-reduction processes in the gasifier.
[0003] Gasifiers typically use a single-channel feeding system. When the feeding equipment malfunctions, the furnace must be shut down and allowed to recover before it can be restarted. This disrupts continuous production and product quality for the energy user. Furthermore, single-channel feeding can lead to uneven material levels within the furnace, resulting in uneven combustion and consequently, a decline in fuel gas quality.
[0004] Therefore, how to design a dual-feed material level control device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] This utility model provides a dual-feed material level control device, which solves the technical problems of existing gasifiers having a single feeding channel and uneven material levels inside the gasifier.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a dual-feed material level control device for regulating the material level in a gasifier, wherein the top of the gasifier is provided with a feeding port, and includes: a material cylinder, a controller, and feeding mechanisms symmetrically arranged on both sides of the gasifier.
[0007] The feed cylinder is inserted into the feeding port; each feeding mechanism includes a conveyor belt assembly and a screw feeding assembly. The conveyor assembly is arranged in an upwardly inclined manner from away from the gasifier to near the gasifier and transports a feeding hopper along its inclined direction; the screw feeding assembly is fixed on one side of the gasifier corresponding to the feeding port and a dropping hopper is fixed on it; the tilted feeding hopper can be connected to the dropping hopper; the feed inlet of the screw feeding assembly is connected to the dropping hopper and its discharge outlet is connected to the feed cylinder; the controller is electrically connected to the conveyor belt assembly and the screw feeding assembly respectively.
[0008] The beneficial effects of this utility model are: it improves the traditional feeding method of gasifiers. By setting a conveyor belt assembly, a screw feeding assembly, a feeding hopper and a dropping hopper on both sides of the gasifier, biofuel can be added to the gasifier separately, and one can be used as a backup to prevent the feeding mechanism from failing and affecting the gasification operation of the gasifier.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, the material cylinder has a conical structure with its smaller end facing downwards.
[0011] The further beneficial effect of adopting the above is that by designing the feed cylinder as a conical structure, the biofuel can be evenly distributed in the gasifier after entering from the top of the feed cylinder.
[0012] Furthermore, it also includes multiple feeders and multiple feeders. The material cylinder extends into the interior of the gasifier and is divided into a feed layer area and a feed layer area from top to bottom. The multiple feeders are fixed at intervals along the circumference of the material cylinder on the inner cylinder wall corresponding to the feed layer area. The multiple feeders are fixed at intervals along the circumference of the material cylinder on the inner cylinder wall corresponding to the feed layer area. The controller is electrically connected to the multiple feeders and the multiple feeders respectively.
[0013] The further beneficial effects of the above are: by fixing multiple feed gauges at intervals along the circumference of the material cylinder on the inner wall of the corresponding feed layer area of the material cylinder, it is possible to monitor in real time whether there is material in the feed layer area of the material cylinder and whether the material is evenly distributed; at the same time, by fixing multiple feed gauges at intervals along the circumference of the material cylinder on the inner wall of the corresponding feed layer area of the material cylinder, it is possible to monitor in real time whether there is material in the feed layer area of the material cylinder and whether the material is evenly distributed.
[0014] Furthermore, it also includes multiple surveillance cameras, which are respectively fixed inside the two feeding hoppers and the two unloading hoppers; the controller is electrically connected to the multiple surveillance cameras respectively.
[0015] The further beneficial effect of adopting the above is that by using multiple monitoring cameras to monitor the two feeding hoppers and two discharge hoppers in real time, biomass fuel can be replenished into the two feeding hoppers and two discharge hoppers in a timely manner.
