The updraft biomass gasification furnace is gradually playing a role in the field of garbage disposal due to its good environmental protection effect. However, the continuous use problem of the updraft garbage gasifier is a difficult problem, and when the charging cover is opened for charging during use, gasified dense smoke can emerge, so that the gasification garbage gasifier can only be intermittently used, namely, the charging cover is opened again for charging after the primary material is completely gasified.
If the updraught type garbage gasification furnace is intended to be continuously used, a screw feeder and a feed hopper are added at the position of a storage box, and garbage in the feed hopper is continuously added into the gasification furnace through the screw feeder according to the requirement of the gasification furnace. The spiral feeder is used for feeding the garbage gasification furnace, the requirements on the shape and the size of garbage materials are high, the materials must be crushed to a certain granularity and can enter the gasification furnace through spiral pushing, and the materials are guaranteed to be extruded through a certain pressure in the pushing process, so that the smoke of the gasification furnace is prevented from exiting the spiral pipe in the garbage pushing process. However, the gasification furnace has low requirements on the shape and the size of the garbage, and common household garbage can be directly added into the gasification furnace for use, which means that a process of crushing and forming the garbage is added after a screw feeder is added, and the process is unnecessary for gasification.
How to add irregular materials such as crop straws and household garbage into a gasification furnace without interrupting the use in the use process of the gasification furnace is a difficult problem. The inventor has provided a device that a double-door feeding box is added above a gasification furnace storage box, a water sealing cover is arranged on the double-door feeding box, and an inner door is arranged at the bottom of the double-door feeding box. When feeding, the inner door is closed, the water sealing cover is opened to add materials, the water sealing cover is covered after the materials are filled, and then the inner door is opened through the rotating device to enable the materials to fall into the gasification furnace. The method is theoretically feasible, but has poor application effect in the practical application process, mainly has poor sealing effect of the inner door, tar and particles can be generated in the garbage gasification process, the design accuracy of the inner door is too high, the operation flexibility can be gradually reduced, and the inner door is inconvenient or even impossible to use.

Optionally, as shown in fig. 2, the feeding sealing device further includes a lifting driving member 80, where the lifting driving member 80 is disposed on the sealing outer cover 41 and connected to the sealing inner cover 70, and the lifting driving member 80 is used to drive the sealing inner cover 70 to lift and position up and down in the sealing outer cover 41 under the action of external force.
In the first embodiment of this alternative, as shown in fig. 1 and 2, the lifting driving member 80 includes a screw sleeve 81 with two ends communicating and an internal thread on the inner wall, a lifting screw 82 cooperatively disposed in the screw sleeve 81, and a supporting plate 83 fixedly connected to the bottom end of the lifting screw 82. The screw bush 81 is vertically disposed and the bottom end is fixed to the outer end surface of the seal housing 41. The outer end surface of the sealing outer cover 41 is provided with a through hole communicated with the screw rod sleeve 81, and the bottom end of the lifting screw rod 82 penetrates through the through hole and then stretches into the sealing outer cover 41. The inner seal cover 70 is sleeved on the outer circle at the bottom end of the lifting screw 82 and is supported on the support plate 83. In operation, the lifting screw 82 is rotated, and the lifting screw 82 drives the seal inner cover 70 to lift up and down in the seal outer cover 41.
Referring to fig. 6 again, since the inner sealing cover 70 is directly sleeved on the outer circle at the bottom end of the lifting screw 82, there is a gap between the inner sealing cover 70 and the lifting screw 82, and the inner sealing cover 70 is supported on the supporting plate 83, so when the lifting screw 82 rotates, the inner sealing cover 70 may be driven to rotate and shake, and shake exists in the descending process of the inner sealing cover 70, which may cause that the blanking frame 30 cannot be accurately covered after the inner sealing cover 70 descends, and the position of the inner sealing cover 70 is inconvenient to manually adjust, so as to affect the sealing effect of the feeding sealing device, therefore, in the preferred embodiment of the invention, the inner sealing cover 70 is in a box cover shape matched with the outer sealing cover 41, so that the blanking frame 30 is accurately covered after the guiding limit of the outer sealing cover 41 descends.

One end of the hinge shaft 62 is fixedly connected with a driving handle 63 extending out of the storage box 42, and the driving handle 63 is used for driving the hinge shaft 62 to rotate under the action of external force so as to enable the blanking plate 61 to rotate around the axis of the hinge shaft 62, so that the discharge door 60 is opened or closed. In operation, the urging drive handle 63 rotates the hinge shaft 62 about its own axis, and thereby drives the blanking plate 61 fixed to the hinge shaft 62 to rotate about the axis of the hinge shaft 62, thereby effecting opening or closing of the discharge door 60.
Further, in order to prevent the hinge shaft 62 from being rotated again to open the discharge door 60, in the present invention, the discharge door 60 further includes a limiting locking member 64 disposed on an outer sidewall of the storage box 42, and the limiting locking member 64 is connected to the driving handle 63 to lock and fix the hinge shaft 62 rotated in place. Specifically, the limiting locking member 64 includes a locking ring fixedly disposed on an outer sidewall of the storage box 42, and a locking hook fixedly connected to the driving handle 63 and cooperatively disposed with the locking ring, where the driving handle 63 drives the blanking plate 61 to rotate in place to lock the blanking plate 61 when the discharging door 60 is closed, so as to further limit the blanking plate 61 to rotate to open the discharging door 60.
Optionally, as shown in fig. 3-5, an outer side wall or an inner side wall of the upper end of the storage tank 42 is provided with a sealing water tank 90 which is convex and annular, and the sealing water tank 90 is filled with sealing liquid 20.
