Description

Technical Field

[0001] The utility model relates to the field of short fiber production equipment, in particular to a production equipment for regenerated polyester staple fiber. Background Art

[0002] Currently, waste textiles will be recycled and reused. For example, regenerated polyester waste is used to spin polyester staple fiber. In this recycling process, for example, the patent application number CN201520985082.X involves an automated production line for spinning polyester staple fiber using regenerated polyester waste. The production line in this patent includes a color matching device, a proportioning device, a drying device, a melting device, a primary filtering device, a pressurizing device, a reaction kettle, a secondary filtering device, a metering device, a bundling device, a drawing device, a shaping device, a crimping device, a cutting device, and a packing device. Such equipment adds a primary filtering device, a pressurizing device, a reaction kettle, and a secondary filtering device on the basis of non-regenerated polyester staple fiber. Due to environmental pollution and other reasons, regenerated polyester waste has more impurities. Although the possibility of impurities entering has been greatly reduced through processes such as crushing, granulating, and decoloring, there will still be a small amount of impurities entering the melting device during the machine screening process. The impurities will be blocked by the filtering device, but when there are more impurities blocked by the filtering device, the impurities will congest at the filtering device, affecting the filtering efficiency of the filtering device. Therefore, it is necessary to manually remove the impurities from the filtering device, reducing the work efficiency. Summary of the Utility Model

[0003] Aiming at the disadvantage of the prior art that the filtering efficiency of the filtering device is reduced due to excessive impurities, the utility model provides a production equipment for regenerated polyester staple fiber.

[0004] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0005] A production equipment for regenerated polyester staple fiber includes a melting device and a filtering device. The filtering device includes a filtering cavity and a filtering element for filtering impurities. The filtering device is cooperatively provided with a pushing and stirring device. The pushing and stirring device includes a pushing and stirring element, a stirring rod, and a power element for driving the stirring rod to rotate. The pushing and stirring element and part of the stirring rod are arranged in the filtering cavity. The pushing and stirring element is connected to the stirring rod, and the stirring rod drives the pushing and stirring element to rotate. The pushing and stirring element is provided with a stirring blade part and a pushing part for stirring the melt. The pushing part can be in contact with the filtering element. The filtering device is provided with a sedimentation tank and a slag discharge valve. The slag discharge valve is communicated with the sedimentation tank. The sedimentation tank is arranged outside the filtering element. When the power element drives the pushing and stirring element to rotate through the stirring rod, the pushing part can drive the impurities on the filtering element into the sedimentation tank.

[0006] Further, the pushing and stirring member further includes a sliding portion, which is slidably matched with the stirring rod. The pushing and stirring member is provided with a pushing and pulling member for driving the sliding portion to move along the stirring rod, and the pushing portion is controlled by the pushing and pulling member to be in a disengaged or abutted state relative to the filter member.

[0007] Further, the sliding portion is in the shape of a circular tube, and the working surface of the pushing portion for pushing impurities is in an arc shape and is tangent to the sliding portion.

[0008] Further, the sliding portion is in the shape of a cylinder and is provided with a spline hole, and the portion where the stirring rod is slidably matched with the sliding portion is in the shape of a spline shaft.

[0009] Further, the stirring rod is provided with a limiting member for restricting excessive sliding of the sliding portion.

[0010] Further, the filter member is provided with a plurality of filter members, and the plurality of filter members are provided with filter holes of different pore sizes. The plurality of filter members are arranged in sequence with the filter holes decreasing from large to small, and the filter member with the largest filter hole is arranged opposite to the melting device.

[0012] Further, the pushing and stirring member, the filter member, and the sedimentation tank are all provided with auxiliary heating devices.

[0013] Further, the auxiliary heating device adopts a hot air heater.

[0014] Due to the adoption of the above technical solutions, the present invention has remarkable technical effects: when the pushing and stirring member is in a normal stirring state, the pushing and pulling member does not move, driving the pushing and stirring member not to abut against the filter member, and the power member drives the stirring rod to rotate, and the stirring blade portion is in a normal state of stirring the melt. When there is a large accumulation of impurities on the filter member, the impurities easily interfere with the melt passing through the filter holes, thereby reducing the melt passing efficiency. The pushing and pulling member can be driven to drive the pushing and stirring member to move towards the filter member below, driving the pushing portion to abut against the surface of the filter member. At this time, when the power member rotates, the impurities on the surface of the filter member can be cleaned, and the impurities on the surface of the filter member are pushed into the sedimentation tank. The impurities and the melt in the sedimentation tank can both be discharged from the filter cavity through the slag discharge valve. Description of the Drawings

The power member 22 is located outside the filtering chamber 10. The power member 22 uses a reduction motor. The output shaft of the power member 22 is connected to one end of the stirring rod 21 through a coupling. The stirring rod 21 is rotatably connected to the filtering chamber 10. The stirring rod 21 is arranged axially along the central axis of the filtering chamber 10. The stirring member 20 includes a stirring blade portion 201, a pushing portion 202, and a sliding portion 203. The sliding portion 203 is in the shape of a circular tube, and the inner hole thereof is in the shape of a spline hole. The stirring rod 21 is provided with a sliding section 210 that cooperates with the sliding portion 203. The sliding section 210 is in the shape of a spline shaft that cooperates with the sliding portion 203. Through the cooperation of the sliding section 210 and the sliding portion 203, when the stirring rod 21 is controlled to rotate by the power member 22, the stirring member 20 is also controlled to rotate synchronously by the stirring rod 21. A limiting member 24 is sleeved on the sliding section 210 of the stirring rod 21. The limiting member 24 is in the shape of a circular ring and is positioned and clamped on the sliding section 210 by screws. The limiting member is used to prevent excessive movement of the sliding portion 203 and avoid the stirring member 20 moving out of the corresponding position. Since a plurality of filtering elements 11 are provided, in this embodiment, seven filtering elements 11 are provided. The stirring blade portion 201 having the same number as the filtering elements is provided on the sliding portion 203. Each stirring blade portion 201 is located above each filtering element 11. The stirring member 20 is provided with a pushing and pulling member 23. The pushing and pulling member 23 uses an electric push rod.

Through the pushing and pulling member 23, the sliding portion 203 can be driven to slide along the central axis direction of the stirring rod 21. Through the sliding portion 203, all the stirring blade portions 201 and the pushing portions 202 connected thereto can be driven to move along the central axis direction of the stirring rod 21.

[0021] The pushing portion 202 is integrally formed with the stirring blade portion 201. The stirring blade portion 201 is in the shape of an inclined blade.

[0022] When the pushing and stirring member 20 is in a normal stirring state, the pushing and pulling member 23 does not move, driving the pushing and stirring member 20 not to abut against the filtering member 11. The power member 22 drives the stirring rod 21 to rotate, and the stirring blade portion 201 is in a normal state of stirring the melt. When there is a large amount of impurities stacked on the filtering member 11, the impurities easily interfere with the melt passing through the filtering holes 12, thereby reducing the melt passing efficiency. The pushing and pulling member 23 can be driven to drive the pushing and stirring member 20 to move towards the filtering member 11 below, driving the pushing portion 202 to abut against the surface of the filtering member 11. At this time, the power member 22 rotates, and the impurities on the surface of the filtering member 11 can be cleaned, and the impurities on the surface of the filtering member 11 are pushed into the sedimentation tank 101.
