Description

Technical Field

[0001] The utility model relates to the technical field of biomass gasifiers, in particular to a heat-insulating feed gate for a biomass gasifier. Background Art

[0002] Biomass gasifier is a kind of equipment with great significance. It converts biomass raw materials into combustible gas through specific technology. This gasifier adopts advanced technology and can efficiently process various types of biomass, such as crop straw, wood waste, etc. During the working process, the biomass undergoes a series of complex thermochemical transformations in the furnace, and the generated gas can be used for various purposes such as power generation and heating. The advantages of biomass gasifier are significant. It not only realizes the effective utilization of waste biomass and reduces resource waste, but also provides a clean and renewable way for energy supply.

[0003] For example, a utility model with announcement number CN206469714U discloses a multi-pipeline aluminum regeneration waste heat furnace feeding device, which includes a waste heat furnace, a tail gas pipe and a drain pipe, and is characterized in that: the upper left side of the waste heat furnace is connected to the tail gas pipe, the lower left side of the waste heat furnace is connected to the drain pipe, a heat insulation board is vertically arranged in the middle of the waste heat furnace, the top of the heat insulation board is connected to the top of the waste heat furnace, a feeding hopper is arranged on the top of the right side of the waste heat furnace, a feeding pipe is vertically arranged at the bottom of the feeding hopper, a top cover is arranged on the top of the feeding hopper, and a gate is arranged; the feeding hopper makes the feeding tend to be continuous fluid feeding, so as to prevent the material in the waste heat furnace from increasing instantly and occupying the position of the aluminum water, so as to ensure the stability of the aluminum water flow; in addition, through the use of the heat insulation board, the temperature on the left side of the waste heat furnace is higher than that on the right side, which reduces the possibility of unmelted material directly entering the drain pipe.

[0004] Similar to the above application, there is still the following disadvantage: after pouring materials into the inner cavity of the gasifier, the sealing performance of the gasifier will be deteriorated. Utility Model Content

[0005] The utility model discloses a heat-insulating feeding gate for a biomass gasifier, aiming to solve the technical problem that the sealing performance of the gasifier deteriorates after pouring materials into the inner cavity of the gasifier.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The cam is an axially rotatable plate that is fixedly connected to the outer wall of the fixing frame, and the cam is connected to the inner wall of the fixing frame at the bottom thereof.

[0008] By setting a limit rod, the sealing mechanism can be limited so that the sealing mechanism can produce a stable vertical up and down movement effect. By setting a sealing mechanism, the gap between the feed pipe and the discharge pipe can be sealed and connected, so that the biomass gasifier produces a sealed and open effect. The setting of the feed pipe and the feeding mechanism can pour the biomass raw materials to be burned into the inner cavity of the biomass gasifier.

[0009] In a preferred embodiment, the number of the limit rods is two, and the two limit rods are symmetrically installed between the opposite surfaces of the bottom frame and the limit frame. The sealing mechanism also includes a support rod, which is fixedly connected to the outer side surface of the limit frame. The number of the support rods is two, and the two support rods are symmetrically arranged, and the ends of the support rods are fixedly connected to a hydraulic press.

[0010] By setting two limit rods, the two sides of the sealing mechanism can be limited respectively, so that the sealing mechanism can produce stable movement when moving. By setting two hydraulic presses, when the blocking plate moves, both ends can receive a downward force, so that the movement of the blocking plate is more stable.

[0011] In a preferred embodiment, the output end of the hydraulic press is fixedly connected to a moving rod, the bottom end of the moving rod is fixedly connected to the upper surface of the blocking plate, the blocking plate is frictionally fitted with the inner wall of the limit frame, the bottom end of the blocking plate is fixedly connected to an extrusion strip, the outer side surface of the extrusion strip is symmetrically installed with a sealing strip, and the sealing strip is extrusion-fitted with the inner wall of the bottom frame.

[0012] By setting up a moving rod, the bottom end of the moving rod can be used to squeeze the baffle plate under the action of a hydraulic press, so that the baffle plate can move up and down. The setting of the extrusion strip and the sealing strip can increase the sealing between the baffle plate and the bottom frame, so that the baffle plate will not shake.

[0013] As can be seen from the above, a heat-insulating feed gate for a biomass gasifier has the following improvements and advantages compared with the prior art:

[0014] First, by providing a sealing mechanism, the gap between the feed pipe and the discharge pipe can be sealed and connected, so that the biomass gasifier can produce a sealed and open effect.

[0015] Secondly, by setting a limiting ball, the rotating sleeve can be limited, so that the rotating sleeve can produce a stable rotation effect on the outer surface of the limiting ball. The setting of the fan blade can produce rotation under the influence of the airflow in the inner cavity of the biomass gasifier, so that the raw materials attached to the inner wall of the feed port can be blown into the inner cavity of the feed pipe.

[0026] Reference Figure 3In a preferred embodiment, the number of the limit rods 5 is two, and the two limit rods 5 are symmetrically installed between the opposite surfaces of the bottom frame 4 and the limit frame 3. By setting two limit rods 5, the two sides of the sealing mechanism 6 can be limited respectively, so that the sealing mechanism 6 can produce stable movement when moving. The sealing mechanism 6 also includes a support rod 66, which is fixedly connected to the outer side of the limit frame 3. The number of the support rods 66 is two, and the two support rods 66 are symmetrically arranged. The ends of the support rods 66 are fixedly connected with a hydraulic press 67. By setting two hydraulic presses 67, when the blocking plate 62 moves, both ends receive a downward force, so that the blocking plate 62 moves more stably.

[0029] Working principle: When it is necessary to pour the biomass raw materials into the biomass gasifier, the operator connects the hydraulic press 67 to the power supply and turns on the switch of the hydraulic press 67, and controls the moving rod 68 to drive the blocking plate 62 to move downward until the through hole 63 on the outer surface of the blocking plate 62 is aligned with the holes of the feed pipe 8 and the through hole plate 11, so as to achieve the effect of pouring the raw materials into the biomass gasifier, and then controls the hydraulic press 67 to move the blocking plate 62 upward, so that the feed pipe 8 and the through hole 63 are aligned with each other. The material plate 11 is blocked to prevent the high-temperature gas in the inner cavity of the biomass gasifier from splashing out; the operator places the raw materials to be poured into the inner cavity of the biomass gasifier into the inner cavity of the feed port 91. When the baffle plate 62 is opened, due to the airflow generated by the combustion in the inner cavity of the biomass gasifier, suction will be generated in the inner cavity of the feed pipe 8, causing the fan blade plate 95 to rotate, thereby allowing the raw materials to quickly pass through and enter the inner cavity of the discharge pipe 12, and finally enter the inner cavity of the biomass gasifier.
