All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to fall within the scope of the present utility model.
Example 1:
in the existing spinning production process, the polymer melt needs to enter a pipeline after flowing out of a screw extruder, enters a filter through the pipeline to remove impurities, the melt leaving the filter also needs to flow into a spinning box through the pipeline, the flow speed of the polymer melt is slow, and the polymer melt needs to be in the pipeline for a long time, so that the production efficiency is low, and the spinning equipment provided by the embodiment 1 of the utility model comprises the screw extruder 1, the filter 2 and the spinning box 3 as shown in fig. 1; the filter 2 comprises a first inlet 21 and a first outlet 22; the melt outlet of the screw extruder 1 is transversely arranged; the first inlet 21 is arranged transversely; the first outlet 22 is vertically disposed; the melt inlet opening of the spinning box 3 is arranged vertically upwards; the first inlet 21 is communicated with a melt outlet of the screw extruder 1 in a sealing way; the first outlet 22 is communicated with the melt inlet of the spinning box 3 in a sealing way; the filter 2 includes a cylindrical filter cylinder 23 and a cylindrical filter core 24; the filter cylinder 23 is vertically arranged; the filter cylinder 23 is internally provided with a cavity; the filter core 24 is coaxially arranged in the accommodating cavity of the filter cylinder 23; the first outlet 22 is provided at the bottom of the filter cylinder 23.
When the spinning device provided by the embodiment 1 of the utility model works, the polymer melt flowing out of the screw extruder 1 directly enters the filter 2 through the first inlet 21, and the melt flowing out of the filter 2 directly flows into the spinning box 3 through the first outlet 22; since the outlet of the screw extruder 1 is generally horizontally arranged, and the melt entering the spinning box 3 needs to vertically enter for facilitating the spinning of the melt, the inlet and the outlet of the filter in the prior art are horizontally arranged, and the polymer melt flowing out of the outlet of the filter needs to be changed in direction through an elbow, in this embodiment, the first inlet 21 communicated with the melt outlet of the screw extruder 1 is horizontally arranged, and the first outlet 22 communicated with the melt inlet of the spinning box 3 is vertically arranged, so that the polymer melt is filtered in the filter and simultaneously changes in moving direction, thereby the filter 2 is directly connected with the screw extruder 1 and the spinning box 3, the arrangement of pipelines is avoided, thereby preventing the polymer melt from staying for a long time and reducing the spinning efficiency.
The spinning equipment provided by the embodiment 1 of the utility model solves the problem that the polymer melt in the prior art needs to be in a pipeline for a long time, and reduces the speed of the whole production; the equipment provided by the embodiment of the utility model can accelerate the polymer melt to enter the spinning box after passing through the filter, and prevent the polymer melt from dragging the spinning production flow in the pipeline for a long time.
The filter 2 needs to be cleaned after a period of operation to ensure that the filter 2 can perform the filtering operation normally, in this embodiment, the first inlet 21 is detachably connected to the melt outlet of the screw extruder 1; the first outlet 22 is detachably connected to the melt inlet of the manifold 3. Filter 2 is removably connected to screw extruder 1 and manifold 3 so that filter 24 can be replaced or cleaned of filter 2 when the internal impurities are excessive.
The flanged pipe is a common method, and as a preferred embodiment, the first inlet 21 is flanged to the melt outlet of the screw extruder 1; the first outlet 22 is flanged to the melt inlet of the spinning beam 3.
Since the flow rate of the polymer melt flowing out of the screw extruder 1 is related to the extrusion speed of the screw extruder 1, but the extruded melt of the screw extruder 1 is not uniform, after the melt enters the filter 3, since the pipe diameter of the filter 3 is fixed, if the melt extruded by the screw extruder 1 is too much, the flow rate of the melt in the filter 3 is fast, if the melt extruded by the screw extruder 1 is too little, and if the melt flow rate in the filter 3 is slow, the melt cannot be uniformly filtered, so that the polymer melt can uniformly flow through the filter cylinder 23 and be filtered by the filter core 24, and in this embodiment, the filter 2 further comprises a guide pipe 25 horizontally arranged by a pipeline; one end of the guide pipe 25 is communicated with the filter cylinder 23 in a sealing way; the other end of the guide tube 25 is a first inlet 21. The polymer melt extruded by the screw extruder 1 passes through the guide pipe 25, is accumulated in the guide pipe 25, and proceeds until the melt enters the filter cylinder 23, the flow direction of the melt is changed due to the blocking of the inner wall of the filter cylinder 23 and the gravity action, and the inertial motion of the melt extruded by the screw extruder 1 in the horizontal direction is counteracted due to the blocking of the inner wall of the filter cylinder 23, so that the melt passes through the filter core 24 in the filter cylinder 23 at a relatively uniform speed by gravity, and the melt can be uniformly filtered.
Since the flow rate of the melt is slowed down when the melt contacts the side wall of the filter cylinder 23, the filter cylinder 23 further comprises a vent 231 in order to allow the melt to smoothly enter through the filter core 24, and in this embodiment, the air pump 4; the vent 231 communicates the cavity of the filter cylinder 23 with the external space; the air outlet of the air pump 4 is communicated with the vent 231 in a sealing way through a pipeline; the vent 231 is disposed vertically above the first outlet 22; the communicating position of the guide pipe 25 and the filter cylinder 23 is lower than the height of the vent hole 231; the first outlet 22 is provided with a valve 221 for controlling the opening and closing of the first outlet 22. The air pump 4 periodically circulates and breathes in and out, when the air pump 4 breathes in, the valve 221 of the first outlet 22 needs to be closed, at this time, the air pressure in the filter 2 is reduced, the melt is more easily guided to the vent holes from the screw extruder 1, when the air pump 4 deflates, the valve 221 is opened, the vent holes 231 blow in air so that the air pressure in the filter 2 is increased, the melt flowing out of the screw extruder 1 has extrusion force and cannot be pushed back to the screw extruder 1, and the melt can more smoothly pass through the filter core 24 right below the vent holes 231 due to the change of the internal air pressure.
In order to prevent the air pump 4 from being sucked into the air pump 4 during the suction process, the air pump 4 is damaged, and in the embodiment, the air pump further comprises a flexible film 5 which can deform along with the air pressure; the flexible membrane 5 is arranged inside the filter cylinder 23; the flexible membrane 5 is hermetically connected to the side wall of the filter cylinder 23; the flexible membrane 5 divides the cavity 23 of the filter cylinder into two spaces which are not communicated with each other; the flexible membrane 5 is arranged horizontally; the vent 231 communicates with a space above the flexible film 5; the guide tube 25 communicates with a space below the flexible film 5; the filter core 24 is disposed vertically below the flexible membrane 5. The air pressure in the filter cylinder 23 can be changed by blowing and sucking the air by the air pump 4, but the air blown by the air pump 4 and the sucked air can not directly contact the melt due to the blocking of the flexible film 5, but the size of the space on the other side of the flexible film 5 is changed by the deformation of the flexible film 5, so that the internal air pressure is changed, and the melt is assisted to pass through the filter core 24; the gas blown out by the air pump is prevented from containing impurities to influence the melt, and the melt is prevented from being sucked into the air pump 4 to influence the normal operation of the air pump.
In summary, the utility model discloses spinning equipment, which relates to the field of spinning, and comprises a screw extruder, a filter and a spinning box; the filter includes a first inlet and a first outlet; the melt outlet of the screw extruder is transversely arranged; the first inlet is transversely arranged; the first outlet is vertically arranged; the melt inlet opening of the spinning box is vertically upwards arranged; the first inlet is hermetically communicated with a melt outlet of the screw extruder; the first outlet is communicated with the melt inlet of the spinning box in a sealing way; the filter comprises a cylindrical filter cylinder body and a cylindrical filter core body; the filter cylinder body is vertically arranged; a containing cavity is formed in the filter cylinder; the filter core body is coaxially arranged in the accommodating cavity of the filter cylinder body; the first outlet is disposed at the bottom of the filter cartridge.
