Description

Technical Field

[0001] The utility model discloses a screw conveyor capable of quickly clearing blockages, belonging to the technical field of screw conveyors. Background Art

[0002] Waste materials such as paper slag produced by paper mills are burned as fuel for incinerators, and electricity is generated by burning paper slag, which not only saves energy but also turns solid waste into treasure. When paper slag is burned in an incinerator to generate electricity, a screw conveyor is often used to transport the paper slag to the incinerator for incineration. The screw conveyor is a machine that uses a motor to drive the screw to rotate and push the material to achieve the purpose of transportation. It can transport horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation.

[0003] Patent No.: CN220244876U, mentions an anti-blocking screw conveyor, which can adjust the amount of material entering from the hopper into the conveying pipe according to the use requirements by setting baffles and adjusting baffles and making them cooperate with each other, so as to avoid more materials entering the conveying pipe with the rotation of the screw at one time, thereby reducing the probability of the conveying pipe being blocked by materials, and finally ensuring the conveying efficiency of the screw conveyor; by setting a positioning handle and making it cooperate with the connecting screw on the adjusting baffle, the adjusting baffle can be fixed, but the device only relies on baffles and adjusting baffles to adjust the material conveying amount for anti-blocking treatment, and the effect is general. Once paper residue accumulates at the feed port of the screw conveyor and causes blockage, it cannot be used for feeding. Now there is an urgent need for a screw conveyor with fast unblocking to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a screw conveyor for rapid blockage removal, comprising a screw conveyor body 1, an anti-blocking feed pipe 4 and a breaking plate 13, the anti-blocking feed pipe 4 is installed on the right side of the upper end of the screw conveyor body 1, a mounting groove 5 is provided on the left side of the anti-blocking feed pipe 4, a horizontal mounting plate 6 is installed at the lower end of the mounting groove 5, a small fixed motor 7 is installed at the upper end of the horizontal mounting plate 6, a swing rod 8 is installed at the shaft end of the small fixed motor 7, two ear plates 10 are installed on the upper side of the left end of the anti-blocking feed pipe 4, and a fixed shaft 11 is fixed between the two ear plates 10 A swing cylinder 12 is sleeved on the annular side of the fixed shaft 11, and a breaking plate 13 is tilted and fixed on the lower end of the swing cylinder 12. A crushing motor 16 is installed on the lower side of the right end of the anti-blocking feed pipe 4, and a crushing shaft 17 is horizontally installed on the lower end of the anti-blocking feed pipe 4 through a bearing. A plurality of crushing blades 18 are installed on the annular side of the crushing shaft 17 at equal distances from left to right. This design solves the problem that the original device only relies on partition plates and adjusting baffles to adjust the material conveying amount for anti-blocking treatment, and the effect is general. Once paper residues accumulate at the feed port of the screw conveyor and cause blockage, the material cannot be fed.

[0019] As the first embodiment of the utility model: a feed pipe 3 is installed on the left side of the lower end of the screw conveyor body 1, a conveying motor 2 is installed on the right end of the screw conveyor body 1, and a rubber butt 9 is installed on the right side of the swing rod 8. The rubber butt 9 is movably abutted against the scattering plate 13. The added rubber butt 9 can prevent the swing rod 8 from directly contacting the scattering plate 13 and causing wear when rotating. A counterweight bar 14 is installed on the lower side of the left end of the scattering plate 13. The added counterweight bar 14 can shift the center of gravity of the scattering plate 13 downward, so that the scattering plate 13 is in a static state when not working. An anti-collision rubber strip 15 is installed on the left end of the counterweight bar 14. The added anti-collision rubber strip 15 can prevent the clockwise swinging scattering plate 13 from directly contacting the inner wall of the anti-blocking feed pipe 4. The shaft end of the crushing motor 16 is transmission-connected to the crushing shaft 17. The added crushing motor 16 can drive the crushing shaft 17 and the multiple crushing blades 18 to rotate.

[0020] As a second embodiment of the present utility model: paper residues are directly added into the anti-blocking feed pipe 4, and then the small fixed motor 7 is started. The shaft end of the small fixed motor 7 will drive the swing rod 8 to rotate in the mounting groove 5, and then drive the rubber head 9 to rotate. When the rubber head 9 rotates, it will hit the scattering plate 13, so that the scattering plate 13 swings counterclockwise, and when the scattering plate 13 swings counterclockwise, it will push and scatter the paper residues in the anti-blocking feed pipe 4, so that the paper residues will not be blocked. At the same time, the crushing motor 16 is started, and the crushing motor 16 will drive the crushing shaft 17 to rotate, and the crushing shaft 17 will drive multiple crushing blades 18 to rotate. The rotating multiple crushing blades 18 will crush the paper residues that fall to the lower end of the anti-blocking feed pipe 4, and then the conveying motor 2 is started. The conveying motor 2 drives the spiral conveying rod in the screw conveyor body 1 to rotate, and the crushed paper residues can be conveyed to other places through the discharge pipe 3.
