Description

Technical Field

[0001] The utility model relates to the technical field of discharging devices, in particular to a material guide plate for a silo of a biomass power plant. Background Art

[0002] Biomass power plant is a power plant that uses straw, grass, bark, roots and other fuels to generate electricity. The above fuel is chopped and sent to the fluidized bed boiler for combustion through the silo in front of the furnace by a screw conveyor. Generally, in order to ensure that the fuel can be continuously transported to the fluidized bed boiler for combustion, a screw conveyor for transporting fuel is often set at the outlet of the silo.

[0003] When there is a lot of fuel in the silo, it may cause fuel blockage in the conveyor when feeding into the screw conveyor. In serious cases, the screw conveyor may even be stuck, which is not conducive to use. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide plate for a silo of a biomass power plant, comprising a guide plate and a silo, wherein two guide plates are provided and symmetrically distributed inside the silo;

[0006] The surface of the material bin is provided with a material guiding component for causing the material guiding plate to reciprocate;

[0007] An auxiliary component is arranged in the material bin, which is used to make the material guide plate shift horizontally while deflecting and guiding the material.

[0008] Optionally, the material guide component includes an electric push rod arranged on the surface of the silo, a rack row is fixedly installed on the output end of the electric push rod, and the inner wall of the silo is rotatably connected with a symmetrically arranged rotating rod 1 and a rotating rod 2, and the surfaces of the rotating rod 1 and the rotating rod 2 are both provided with arc-shaped protrusions;

[0009] The invention also comprises two sleeves, which are respectively sleeved on the surfaces of the first rotating rod and the second rotating rod.

[0010] Optionally, the surface of the rotating rod one is fixedly connected to gear one meshing with the rack row, the surface of the silo is fixedly connected to rotating rod three, the surface of the rotating rod three is fixedly connected to gear two meshing with the rack row, and the surface of the rotating rod two is fixedly connected to gear three meshing with gear two.

[0011] Optionally, the auxiliary component includes a connecting rod fixedly connected to the surface of the guide plate, a sphere is fixedly connected to the end of the connecting rod, and an arc block is fixedly connected to the inner wall of the silo.

[0012] Optionally, a circular ring is rotatably connected to the surface of the sleeve, and a spring is provided between the circular ring and the inner wall of the silo.

[0013] Optionally, a sliding block is fixedly connected to the surface of the rack row, and a rectangular notch is provided on the surface of the silo for the sliding block to slide and extend out.

[0014] Optionally, the upper surface of the silo is fixedly connected to a feed pipe, and the lower surface of the silo is fixedly connected to a discharge pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model controls the electric push rod to reciprocate and extend, and under the meshing action of the rack row, gear one, gear two and gear three, the two guide plates can be deflected in the direction of moving away from each other and then reset. In this process, the gap between the two guide plates will gradually increase to discharge the fuel, thereby preventing a large amount of fuel accumulated on the guide plates from falling into the discharge pipe at one time, solving the problem that the screw conveyor may be blocked or stuck due to excessive fuel in the silo, and ensuring the continuous transportation of the fuel.

[0017] The utility model can control the amplitude of the reciprocating swing of the two guide plates by controlling the reciprocating extension distance of the electric push rod. When the fuel in the silo is large, the delivery of the fuel in the feed pipe is stopped first, and then the reciprocating extension distance of the electric push rod is reduced, so that the gap for unloading the materials leaking between the two guide plates can be reduced, so as to better avoid the blockage of the fuel in the discharge pipe and the screw conveyor below.

[0018] The utility model can control the reciprocating extension of the electric push rod to make the guide plate reciprocate and deflect, and at the same time, under the action of the spring, the sphere and the arc block, the two sleeves can also drive the two guide plates to move back and forth in a small range, so that the fuel accumulated on the guide plate can be shaken off, avoiding the problem of fuel accumulation on the guide plate and affecting the discharge of the material, thereby improving the discharge effect of the guide plate, and is worthy of promotion and use.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figures 1 to 4 The utility model provides a biomass power plant silo guide plate, including a guide plate 11 and a silo 1. Two guide plates 11 are provided and symmetrically distributed inside the silo 1. The surface of the silo 1 is provided with guide components and auxiliary components.

[0026] The upper surface of the silo 1 is fixedly connected with a feed pipe 2 , and the lower surface of the silo 1 is fixedly connected with a discharge pipe 3 .

[0027] The material guide component includes an electric push rod 4 arranged on the surface of the silo 1, a rack row 5 is fixedly installed on the output end of the electric push rod 4, and the inner wall of the silo 1 is rotatably connected with a symmetrically arranged rotating rod 1 7 and a rotating rod 2 8, and the surfaces of the rotating rod 1 7 and the rotating rod 2 8 are both provided with arc-shaped protrusions 15;

[0028] It also includes two sleeves 14, which are respectively sleeved on the surfaces of the rotating rod 1 7 and the rotating rod 2 8.

[0029] The surface of the rotating rod 7 is fixedly connected to a gear 6 meshing with the rack row 5, the surface of the silo 1 is fixedly connected to a rotating rod 3, the surface of the rotating rod 3 is fixedly connected to a gear 2 9 meshing with the rack row 5, and the surface of the rotating rod 2 8 is fixedly connected to a gear 3 10 meshing with the gear 2 9.

[0030] A sliding block 13 is fixedly connected to the surface of the rack row 5 , and a rectangular notch 12 is provided on the surface of the silo 1 for the sliding block 13 to slide and extend out.

[0031] More specifically, when this embodiment is used, Figure 1 As shown, pour fuel into the feed pipe 2, and connect the discharge pipe 3 with the feed port of the screw conveyor, then control the electric push rod 4 to extend reciprocatingly, drive the rack row 5 to move reciprocatingly, and with the reciprocating movement of the rack row 5, the gear 1 6 and the gear 2 9 will reciprocate synchronously and in the same direction, and under the meshing action of the gear 2 9 and the gear 3 10, the gear 3 10 can reciprocate in the opposite direction of the gear 1 6.

[0032] like Figure 2 and Figure 4 As shown, during this process, the rotating rod 1 7 will rotate clockwise and the rotating rod 2 8 will rotate counterclockwise synchronously. Since the two sleeves 14 are sleeved on the outer sides of the arc-shaped protrusion and the rotating rod 1 7 and the arc-shaped protrusion and the rotating rod 2 8, the reverse rotation of the rotating rod 1 7 and the rotating rod 2 8 will cause the sleeve 14 to drive the two guide plates 11 to deflect away from each other and then reset. During this process, the gap between the two guide plates 11 will gradually increase, so that the fuel on the two guide plates 11 can fall into the discharge pipe 3 below, so that it can be transported to the screw conveyor below to complete the fuel transportation.

[0033] It is worth noting that since the gap between the two guide plates 11 is gradually enlarged, it is possible to prevent a large amount of fuel accumulated on the two guide plates 11 from falling into the discharge pipe 3 at one time, thereby avoiding the problem of clogging of the discharge pipe 3, thereby avoiding the problem of clogging or jamming of the screw conveyor below, and ensuring the continuous delivery of fuel.

[0034] Furthermore, by controlling the reciprocating extension distance of the electric push rod 4, the reciprocating swing amplitude of the two guide plates 11 can be controlled. When there is a lot of fuel in the silo 1, the delivery of fuel in the feed pipe 2 can be stopped first, and then the reciprocating extension distance of the electric push rod 4 can be reduced, so that the gap for unloading materials leaking between the two guide plates 11 can be reduced, so as to better avoid the blockage of fuel in the discharge pipe 3 and the screw conveyor below.

[0035] Embodiment 2, based on the above embodiment:

[0036] Furthermore, the auxiliary components in the first embodiment are disclosed, and the auxiliary components include a connecting rod 17 fixedly connected to the surface of the guide plate 11 , a sphere 18 is fixedly connected to the end of the connecting rod 17 , and an arc block 20 is fixedly connected to the inner wall of the silo 1 .

[0037] A circular ring 19 is rotatably connected to the surface of the sleeve 14 , and a spring 16 is provided between the circular ring 19 and the inner wall of the silo 1 .

[0038] More specifically, when this embodiment is used, Figure 2 and Figure 3 As shown, when the electric push rod 4 is controlled to reciprocate and extend so that the guide plate 11 is reciprocatingly deflected, the ball 18 at the end of the connecting rod 17 is also reciprocatingly deflected with the axis of the sleeve 14 as the center. When the ball 18 contacts the arc block 20, the guide plate 11 is pushed in the direction close to the rack row 5. In this process, the spring 16 is also squeezed. When the ball 18 is separated from the arc block 20, under the action of the elastic potential energy of the spring 16, the ball 18 and the guide plate 11 are driven to reset. That is, at this time, with the deflection of the ball 18, the two sleeves 14 can also drive the two guide plates 11 to reciprocate slightly on the rotating rod 2 8 and the rotating rod 1 7, so that the fuel on the guide plate 11 can be better shaken off, avoiding the problem that some fuel may accumulate on the guide plate 11 and affect the unloading, thereby improving the discharging effect of the guide plate 11 and making it more practical.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
