[0002] When the current power plant is generating thermal power, the coal powder in the coal storage bin passes through the vertical funnel of the central feeder and falls onto the conveyor belt below the central feeder. The conveyor belt then transports the coal powder to the furnace for combustion to generate heat energy. When the water content of the coal is slightly high, it is easy to cause blockage in the vertical funnel of the central feeder, causing the central feeder to be unable to smoothly discharge coal, and the blocked part needs to be unblocked. The current unblocking method is to open the inspection door on the outer wall of the vertical funnel of the central feeder, manually insert an iron rod into the inner cavity of the vertical funnel through the inspection door hole, and the operator stands outside the inspection door hole, holding the iron rod, moving it up and down, and hitting the blocked part to unblock the blockage.

[0021] The structure of the present invention is further described below with reference to the accompanying drawings and by way of examples. It should be noted that the present examples are descriptive rather than restrictive.

[0022] A device for clearing coal blockage in a central feeder, see Figure 1-Figure 3 The invention point is: it includes a support seat 3, a dredging rod 1, a connecting rod 2 and a force application rod 5.

[0023] The support seat is the base of the dredging device. On the one hand, it realizes the connection between the dredging action rod, the connecting rod and the force action rod. On the other hand, it realizes the support and stability of the entire dredging device on the lower edge of the detection door hole of the central feeder, thereby realizing the positioning and installation of the entire dredging device on the central feeder.

[0024] The support seat is composed of a seat bottom part 3.3 and a support rod part 3.2 connected to the base part, and the overall height of the support seat is less than the height of the detection door hole of the center feeder. A card slot 3.1 is provided at the base end, and the width of the card slot matches the wall thickness of the lower edge of the inspection door hole, so that the support seat can be clamped on the lower edge of the detection door hole of the center feeder through the card slot to form a fulcrum. The shape of the card slot is preferably an arc card slot that matches the shape of the lower edge. In order to improve the stability of the support seat clamped on the lower edge of the detection door hole of the center feeder, the seat bottom part can adopt an extended base structure relative to the support rod part, and two left and right card slots are provided on the base. The two card slots are respectively clamped on the two sides of the lowest edge of the detection door hole of the center feeder to achieve a stable support effect. Hinge holes are respectively provided in the middle and upper parts of the support rod.

[0025] The force-applying rod is a two-section structure, consisting of a rod connecting section 5.1 and a force-applying section 5.2. In the present invention, the rod connecting section and the force-applying section are arranged at an obtuse angle, the rod connecting section is a crossbar section, and the force-applying section is a downward bending rod section. A hinge hole is respectively arranged at the head and near the tail of the connecting rod section. The hinge hole at the tail of the force-applying rod is hinged with the hinge hole at the middle position of the support rod through the first hinge shaft 6.

[0026] The dredging rod is a vertical rod, and a conical dredging head is provided at the upper end of the dredging rod for direct contact with the coal blockage part. A hinge hole is provided at the middle and lower part and the lower end of the dredging rod respectively. The hinge hole at the lower part of the dredging rod is hingedly connected with the hinge hole at the head of the force application rod through the second hinge shaft 7.

[0027] Both ends of the connecting rod are provided with hinge holes, wherein the hinge hole at one end is hingedly connected to the hinge hole in the lower part of the dredging rod through the third hinge shaft 8, and the hinge hole at the other end is hingedly connected to the hinge hole in the upper part of the support rod of the support seat through the fourth hinge shaft 4.

[0028] In the above device, for easy operation, a handle is mounted on the force application section of the force application rod, and the handle is made of silicone or rubber. In order to reduce the card-mounting wear on the lower edge of the detection door hole of the center feeder, it is preferred to wrap a plastic sleeve and a rubber sleeve in the card slot, so that the soft material is in direct contact with the lower edge of the detection door hole to achieve the effect of reducing wear.

[0029] The support seat, the dredging rod, the connecting rod and the force-applying rod are connected through four hinge shafts to form a parallelogram connecting rod mechanism.

[0030] The method of using the coal blockage dredging device for the feeder in this center is:

[0031] The coal blockage unblocking device for the center feeder is clamped on the lower edge of the detection door hole 9.1 of the center feeder 9 through the clamping slot at the lower part of the support seat. At this time, most of the rod connecting sections of the unblocking rod, the connecting rod and the force-applying rod extend into the inner cavity of the vertical funnel of the center feeder; and the force-applying section of the force-applying rod is located outside the center feeder. Then the force-applying section is manually pressed down to make the force-applying rod rotate around the center of the first hinge axis. At this time, the rod connecting section rotates upward, pushing the unblocking rod upward, so that the conical unblocking head of the unblocking rod acts on the position of coal blockage. Through multiple actions, the blocked part can be smoothly unblocked.
