Description

Technical Field

[0001] This utility model relates to the field of chemical fiber textile equipment technology, specifically to a pre-spinning oiling agent filtration and conveying system. Background Technology

[0002] In the chemical fiber spinning production process, the recycling of pre-spinning oil (especially recycled oil) is a key link in reducing production costs. However, the oil filtration and conveying system widely used in the industry has fundamental defects in its process design, which leads to frequent equipment failures and seriously restricts production stability and oil utilization efficiency.

[0003] Existing systems generally employ a "solenoid valve first, filter element later" delivery process: the oil in the storage tank (containing a large amount of recycled oil) first enters the solenoid valve through the delivery pipeline. After the flow rate is regulated by the solenoid valve, it is then delivered to the filter element for impurity filtration. The core problem with this process is that the recycled oil inevitably contains impurities such as waste yarn lint, metal shavings, and polymer particles generated during the spinning process. These impurities enter the solenoid valve and delivery pipeline directly without filtration, causing frequent solenoid valve malfunctions and pipeline blockages. Utility Model Content

[0004] The purpose of this invention is to provide a pre-spinning oil filtration and delivery system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-spinning oil agent filtration and conveying system, comprising a filter, a solenoid valve, and an oil storage tank. The oil outlet of the oil storage tank is connected to the input end of the filter via a conveying pipe, for conveying the oil agent to be filtered to the filter. The output end of the filter is connected to the input end of the solenoid valve via a conveying pipe. The output end of the solenoid valve is used to connect to the oil supply end of the spinning machine, and the solenoid valve controls the on / off conveying and flow regulation of the filtered oil agent.

[0006] Furthermore, the filter includes an inner barrel and an outer barrel detachably fitted onto the outside of the inner barrel. The top of the outer barrel has an opening adapted to the outer diameter of the inner barrel, through which the inner barrel is inserted into the outer barrel. The bottom of the inner barrel has an opening communicating with the inside of the outer barrel. Several filter elements are concentrically fitted inside the inner barrel, and the pore size of the filter elements decreases sequentially from the outside to the inside, dividing the inner barrel into several independent cavities. The top of the inner barrel is provided with an oil inlet and an oil outlet. The oil inlet communicates with the outermost cavity, and the oil outlet communicates with the innermost cavity. After the filter oil enters the outermost cavity through the oil inlet, it is filtered sequentially by each filter element and then enters the innermost cavity, before being discharged to the solenoid valve through the oil outlet.

[0007] Furthermore, both the inner and outer tubs are coaxial cylindrical structures, with the inner wall of the outer tub fitting against the outer wall of the inner tub, and the outer tub being able to rotate relative to the central axis of the inner tub; when the inner and outer tubs are relatively fixed, the bottom end of the inner tub is tightly attached to the bottom end of the outer tub to achieve a seal.

[0008] Furthermore, a number of scrapers corresponding to each filter element are fixedly arranged at the bottom of the inner side of the outer barrel, and the scrapers are arranged in a circumferential array and closely attached to the inner and outer walls of the filter element to remove impurities attached to the surface of the filter element.

[0009] Furthermore, the top ends of the inner and outer tubs are provided with corresponding first and second flange rings, which are fixedly connected by fixing bolts and nuts.

[0010] Furthermore, the second flange ring is provided with several arc-shaped sliding holes that are adapted to the fixing bolts, and the center of the arc-shaped sliding holes coincides with the central axis of the inner barrel, so as to accommodate each fixing bolt to rotate around the central axis of the inner barrel.

[0011] Furthermore, the number of fixing bolts is less than the number of circumferential arrays of the scrapers corresponding to a single filter element.

[0012] Furthermore, the number of filter elements is set to three, and the three filter elements divide the interior of the inner barrel into four independent cavities.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The pre-spinning oil filter conveying system adopts the conveying process of "filter first, then solenoid valve". The oil is first filtered by the filter to remove impurities such as waste yarn and lint, and then enters the solenoid valve. Since the impurities have been intercepted in advance, the problems of solenoid valve failure and conveying pipeline blockage are reduced.

[0015] (2) By using multiple filter elements to form gradient filtration, the filtration effect is better;

[0016] (3) By setting an outer barrel and scraper, it is convenient to clean the filter element, reduce the occurrence of clogging, and facilitate the collection and treatment of impurities. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1 This utility model provides an embodiment of a pre-spinning oil filtration and conveying system, including a filter 1, a solenoid valve 2, and an oil storage tank 3. The oil outlet of the oil storage tank 3 is connected to the input of the filter 1 through a conveying pipe. A conveying pump (not shown in the figure) is provided at the outlet of the oil storage tank 3 for conveying the oil to be filtered to the filter 1. The output of the filter 1 is connected to the input of the solenoid valve 2 through a conveying pipe. The output of the solenoid valve 2 is used to connect to the oil supply end of the spinning machine. The solenoid valve 2 controls the on / off conveying and flow regulation of the filtered oil. The conveying process adopts "filter first, then solenoid valve". The oil first passes through the filter 1 to remove impurities such as waste yarn and lint, and then enters the solenoid valve 2. Since the impurities have been intercepted in advance, it can avoid impurities from entangled in the valve core of the solenoid valve 2 or stuck in the valve seat gap. This reduces the problem of solenoid valve 2 failure, such as valve core jamming or sealing failure, as well as blockage of the conveying pipe, such as impurities accumulating at pipe bends and interfaces, thus ensuring the continuity of oil delivery.

[0024] Please see Figure 2-4 The filter 1 is the core filter component, including an inner barrel 4 and an outer barrel 5 that is detachably fitted to the outside of the inner barrel 4. The top of the outer barrel 5 has an opening that matches the outer diameter of the inner barrel 4, through which the inner barrel 4 is inserted into the outer barrel 5. The bottom of the inner barrel 4 has an opening that communicates with the inside of the outer barrel 5. Both the inner barrel 4 and the outer barrel 5 are coaxial cylindrical structures, and the inner wall of the outer barrel 5 fits against the outer wall of the inner barrel 4. The outer barrel 5 can rotate relative to the central axis of the inner barrel 4. To improve the sealing performance, a sealing ring (not shown in the figure) can be provided on the contact surface between the two.

[0025] Three filter elements 6 are concentrically nested inside the inner barrel 4. Each filter element 6 is a cylindrical structure with two open ends, and they are coaxially arranged with the inner barrel 4, dividing the interior of the inner barrel 4 into four independent cavities. The height of the three filter elements 6 is the same as the internal height of the inner barrel 4, and their tops are fixedly connected to the top of the inner barrel 4. When the inner barrel 4 and the outer barrel 5 are relatively fixed, the bottom ends of the inner barrel 4 and the filter elements 6 are tightly pressed against the bottom of the inner end of the outer barrel 5, achieving a seal. The pore size on the side wall of the filter element 6 decreases progressively from the outside to the inside, being 20μm, 10μm, and 5μm respectively, achieving gradient filtration of the oil and resulting in better filtration.

[0026] The top of the inner barrel 4 is welded with an oil inlet 7 and an oil outlet 8. The oil inlet 7 is connected to the outermost cavity, and the oil outlet 8 is connected to the innermost cavity. After the filter oil enters the outermost cavity from the oil inlet 7, it passes through the 20μm, 10μm and 5μm filter elements 6 in sequence before entering the innermost cavity, gradually removing impurities of different particle sizes, and then is discharged to the solenoid valve 2 through the oil outlet 8.

[0027] The bottom of the inner barrel 5 is fixedly provided with several scrapers 9 that correspond one-to-one with each filter element 6. Each filter element 6 is specifically provided with four sets of scrapers 9. The four sets of scrapers 9 are arranged in a circumferential array, and there are two scrapers 9 in each set. They are tightly attached to the inner and outer walls of the filter element 6 and are used to remove impurities attached to the inner and outer surfaces of the filter element 6 when it rotates.

[0028] In this embodiment, the top ends of the inner tub 4 and the outer tub 5 are provided with corresponding first flange rings 10 and second flange rings 13. The first flange rings 10 and the second flange rings 13 are fixedly connected by fixing bolts 11 and nuts 12. There are three fixing bolts 11 and nuts 12 respectively. The first flange ring 10 has three through holes adapted to the fixing bolts 11. The second flange ring 13 has three arc-shaped sliding holes 1301 adapted to the fixing bolts 11. The center of the arc-shaped sliding holes 1301 coincides with the central axis of the inner tub 4, which is used to accommodate the three fixing bolts 11 to rotate around the central axis of the inner tub 4. During assembly, the outer tub 5 is sleeved on the outside of the inner tub 4 from bottom to top. Then, the bolts are passed through the through holes and arc-shaped sliding holes 1301 on the first flange ring 10 in sequence and then threaded with the nuts 12 to achieve relative fixation of the inner tub 4 and the outer tub 5. When it is necessary to clean the filter element 6, the nuts 12 are loosened to allow the inner tub 4 and the outer tub 5 to rotate relative to each other. It is convenient to use.

[0029] In some other embodiments, the fixing bolts 11 and scrapers 9 may be set to other quantities to ensure that when the outer barrel 5 is driven to rotate, the fixing bolts 11 slide from one end of the arc-shaped sliding hole 1301 to the other end, and the multiple scrapers 9 can clean the filter element 6 from all directions.

[0030] Working principle: During operation, the delivery pump draws the oil from the oil storage tank 3. First, it passes through the three-stage filtration of the filter 1 to remove waste yarn, lint and other impurities mixed in with the oil. Then, the solenoid valve 2 regulates the delivery of the oil and the flow rate to avoid oil leakage, blockage and overflow.

[0031] After working for a period of time, impurities will adhere to the surface of filter element 6, causing a decrease in filtration efficiency. At this time, first turn off the delivery pump and solenoid valve 2, loosen nut 12 to release the relative fixation of inner barrel 4 and outer barrel 5, and then push outer barrel 5 by hand to rotate around the central axis of inner barrel 4. Fixing bolt 11 slides in arc-shaped sliding hole 1301 and plays a limiting role. At this time, scraper 9 rotates synchronously with outer barrel 5, and scraper 9 moves relative to the inner and outer walls of each filter element 6 to scrape off the impurities adhering to filter element 6 to avoid affecting the filtration effect. Impurities fall into the bottom of outer barrel 5 through the through hole at the bottom of inner barrel 4. Then tighten nut 12 to continue filtration. If there are many impurities accumulated at the bottom of outer barrel 5, the fixing bolt 11 can be completely removed, outer barrel 5 can be removed from inner barrel 4, poured out and cleaned of impurities, and then reassembled. The operation is flexible.
