Description

Technical Field

[0001] This utility model relates to the technical field of biomass boilers, and in particular to a fully enclosed dust-free unloading system for biomass. Background Technology

[0002] When using a biomass boiler, biomass fuel needs to be placed in the feed bin. Biomass pellets are usually packaged in bags, and the bags need to be opened before being poured into the feed bin. A lot of dust is generated during the pouring process.

[0003] For example, patent application number CN202121683995.8 discloses a biomass feeding device. In this patent, biomass fuel is discharged from the discharge port of the elevator 7 through the elevator 7 and enters the feeding hopper 1 through the feed inlet 12 of the feeding hopper 1. The motor 8 drives the upper rotating shaft 21 to rotate through the first pulley 81, the second pulley 82 and the belt. The upper rotating shaft 21 drives the sun gear 31 to rotate. Since the gear ring 33 is fixed, the planetary gear 32 starts to rotate around the sun gear 31. At the same time, the direction of rotation of the planetary gear 32 around the sun gear 31 is opposite to the direction of rotation of the sun gear 31. In this way, the upper rotating shaft 21 and the lower rotating shaft 22 rotate simultaneously with different speeds and directions of rotation. During the falling process, the biomass fuel is struck by the upper striking rod 4 and the lower striking rod 5 in turn, which disperse the biomass fuel with different directions and striking forces, so that the biomass fuel is fully dispersed.

[0004] The current feeding method generates a large amount of dust, which floats in the air and can be inhaled by people. Utility Model Content

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-4 In this first embodiment, a fully enclosed dust-free unloading system for biomass includes...

[0032] Feeding bin 10;

[0033] Two clamping plates 60 are movably disposed in the upper port of the feeding bin 10, and the center of the opposite surfaces of the two clamping plates 60 are respectively provided with positioning grooves 61;

[0034] Two dustproof cloths 70 are respectively set on the opposite side of the two clamping plates 60 on one side and on the inner wall of the feeding hopper 10 on the other side.

[0035] The two clamps 60 are brought close to each other to unfold the dustproof cloth 70, so that the clamps 60 and the dustproof cloth 70 seal the feed hopper 10.

[0036] Two rotating columns 81 are rotatably installed inside the feeding bin 10;

[0037] Two blades 80 are respectively mounted on two rotating columns 81, and the blades 80 are used to cut open the packaging bag;

[0038] The crossbeam plate 31 is located directly above the upper opening end of the feeding hopper 10;

[0039] The movable plate 30 is movably mounted on the crossbeam plate 31;

[0040] An electric take-up roller 40 is mounted on a movable plate 30;

[0041] The chain 51 has one end mounted on the winding roller of the electric winding roller 40 and the other end mounted on a hook 50.

[0042] Foam sleeve 52 is fixedly fitted onto chain 51 to fill the two positioning slots 61.

[0043] This embodiment is implemented as follows:

[0044] In use, the hook 50 is first hooked onto the biomass fuel packaging bag. Then, the electric winding roller 40 winds up the chain 51 to lift the packaging bag upwards. Then, the moving plate 30 moves to send the packaging bag above the feeding bin 10. Then, the electric winding roller 40 releases the chain 51, allowing the packaging bag to enter the feeding bin 10. At this time, the foam sleeve 52 is aligned with the positioning groove 61. Then, the two clamping plates 60 move, causing the positioning groove 61 to clamp the foam sleeve 52, and the two clamping plates 60 close. During this process, the dustproof cloth 70 unfolds and, together with the clamping plates 60, seals the opening of the feeding bin 10, thus preventing dust leakage.

[0045] The advantage of this application over existing technologies is that it enables dust-free material loading.

[0046] Please see Figure 1 The crossbeam plate 31 is provided with a first guide rod 33 and a first ball screw module 32. The ball screw of the first ball screw module 32 passes through the moving plate 30 and is threadedly connected to the moving plate 30. The first guide rod 33 slides through the moving plate 30.

[0047] The first ball screw module 32 can drive the moving plate 30 to move along the first guide rod 33.

[0048] Please see Figure 1 A positioning sleeve 21 is fixedly fitted on the feeding bin 10, and the positioning sleeve 21 is fixedly connected to the crossbeam plate 31 through several support frames 20.

[0049] The positioning sleeve 21 is connected to the feeding bin 10 by the positioning sleeve 21 and the support frame 20.

[0050] Please see Figure 1 , 2 3, 4, The feeding bin 10 is equipped with a second ball screw module 63 and two second guide rods 64. The ball screw of the second ball screw module 63 has two opposite threads. The two opposite threads on the ball screw of the second ball screw module 63 are respectively threaded to two clamping plates 60. The two second guide rods 64 slide through the two clamping plates 60.

[0051] The second ball screw module 63 can drive the two clamping plates 60 to move along the second guide rod 64 in a direction that is closer to or further away from each other.

[0052] Please see Figure 3 , 4 The inner wall of the feeding bin 10 has grooves 62 at the front and rear ends of the clamping plate 60, and the front and rear ends of the clamping plate 60 slide into the grooves 62. The front and rear ends of the dustproof cloth 70 also slide into the grooves 62.

[0053] The groove 62 allows for better dust protection of the clamp 60 and the dustproof cloth 70.

[0054] Please see Figure 1 , 2 3. A servo motor 82 is installed on the outer wall of the feeding bin 10 at the position of each rotating column 81. The output end of the servo motor 82 is fixedly connected to the rotating shaft of the rotating column 81.

[0055] The servo motor 82 can drive the rotating column 81 to rotate.

[0056] The above are merely preferred embodiments of this utility model.
