Description

Technical Field

[0001] This utility model relates to the technical field of aluminum wire drawing liquid filtration devices, and in particular to a water-based aluminum wire drawing liquid circulation filtration device. Background Technology

[0002] During the water-based aluminum wire drawing process, the drawing fluid will continuously rub against the aluminum surface, generating debris, impurities, and some precipitates due to chemical reactions. If these substances are not cleaned and filtered in time, they will seriously affect the performance of the drawing fluid and reduce the drawing quality, such as causing more scratches on the aluminum wire surface and a decrease in smoothness. Therefore, the drawing fluid needs to be filtered through a filtration device.

[0003] According to the proposed drawing fluid master box in announcement number CN220479075U, the drawing fluid is introduced into the filter box through a connecting hopper. The drawing fluid is filtered through two filter screens. The drawing fluid undergoes two layers of step-by-step filtration to remove metal debris. The pre-cleaned drawing fluid is then introduced into the master box through a guide plate and a connecting pipe, achieving advantages such as good impurity removal effect and solving the problem of poor impurity removal effect that could not meet production requirements.

[0004] Existing circulating filtration devices primarily remove impurities, debris, and sediments from water-based aluminum wire drawing liquids using fixedly installed filter screens. Over time, these impurities gradually clog the filter screens, leading to decreased filtration efficiency or even complete failure. Currently, most equipment requires manual inspection and replacement of the filter screens periodically. This not only increases operating costs and maintenance difficulty but may also cause production interruptions or product quality issues due to failure to replace them in a timely manner.

[0005] Therefore, there is an urgent need to provide a water-based aluminum wire drawing liquid circulation filtration device to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water-based aluminum wire drawing liquid circulation filtration device.

[0007] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a water-based aluminum wire drawing liquid circulation filtration device is provided, including a first filter box and a second filter box, wherein the first filter box and the second filter box are provided in three sets and connected end to end;

[0008] The bottom of the first filter box and the second filter box are both fixed with a liquid outlet bend, one end of each of the two liquid outlet bends is fixed with a one-way valve, and a liquid outlet tee is fixed between the two one-way valves.

[0009] The top of the first and second filter boxes is provided with a filtration mechanism to ensure stability throughout the entire filtration cycle, and the filter mechanism is provided with a switching mechanism that can automatically replace the filter with a spare filter.

[0010] Through the above technical solution, the water-based aluminum wire drawing liquid flows out from the outlet bend of the first filter box, and then flows to the next process through the one-way valve and the outlet tee.

[0011] The present invention is further configured such that: the filtration mechanism includes filter screens respectively fitted into the top of the first filter box and the second filter box, and the filter screens are provided in three types, namely coarse filter screen, fine filter screen and ultrafine filter element.

[0012] Through the above technical solution, the coarse filter removes large particulate impurities from the drawing liquid, the fine filter further filters out smaller particulate impurities, and the ultrafine filter element performs final purification of the drawing liquid to ensure the purity of the liquid.

[0013] The present invention is further configured such that: the top of the first filter box and the second filter box are both fixed with mounting box covers by bolts, and the top of the two mounting box covers are both fixed with liquid inlet bends.

[0014] The above technical solution allows for the removal and installation of the housing cover, making it convenient to maintain and replace old filters.

[0015] The present invention is further configured such that: one end of the liquid inlet bend on one side is fixed with a liquid inlet tee pipe, and one end of the liquid inlet bend on the other side is fixed with an electric valve that is fixedly connected to the liquid inlet tee pipe; and a fixing ring is integrally provided on the inner wall of the liquid inlet tee pipe.

[0016] Through the above technical solution, the water-based aluminum wire drawing liquid flows in from the inlet tee pipe, and then enters the first filter box through the electric valve and the inlet bend pipe.

[0017] The present invention is further configured such that: the switching mechanism includes an installation sleeve fixed to one side wall of the inner cavity of the liquid inlet tee pipe, and a telescopic sleeve is slidably installed on the outside of the installation sleeve.

[0018] With the above technical solution, the telescopic sleeve can be retracted when compressed by installing the sleeve.

[0019] The present invention is further configured such that: a first sealing ring is fixed to the outside of the mounting sleeve and is sealed to the telescopic sleeve, and a second sealing ring is fixed to the outside of the telescopic sleeve and is sealed to the fixed ring.

[0020] Through the above technical solution, the first sealing ring prevents water-based aluminum wire drawing liquid from seeping into the inside of the installation sleeve, and the second sealing ring prevents water-based aluminum wire drawing liquid from seeping into the inside of the inlet bend.

[0021] The present invention is further configured such that: a limit ring is fixed at one end of the telescopic sleeve, a cylindrical spring is fixed between the mounting sleeve and the telescopic sleeve, and a contact sensor is fixed on one side wall of the inner cavity of the mounting sleeve.

[0022] Through the above technical solution, the limiting ring prevents the telescopic sleeve from separating, the cylindrical spring drives the telescopic sleeve to extend through the mounting sleeve, and after the telescopic sleeve retracts, it will press the contact sensor, causing the contact sensor to drive the electric valve to close.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. This utility model has a switching mechanism that can automatically switch to a backup filter after the filter screen becomes clogged, without manual intervention, reducing downtime, improving production efficiency and equipment utilization. At the same time, the electric valve is closed by a contact sensor, which facilitates the replacement of the clogged filter screen, making daily maintenance and component replacement more convenient and reducing maintenance difficulty and cost.

[0025] 2. This utility model has a filtration mechanism that uses three sets of filtration devices to perform coarse filtration, fine filtration and ultrafine filtration on water-based aluminum wire drawing liquid, which significantly improves the filtration accuracy and efficiency. Each set of filtration devices is equipped with two filter screens that operate alternately to ensure a stable filtration effect throughout the entire filtration cycle and improve product quality.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figures 1-4 A water-based aluminum wire drawing liquid circulation filtration device includes a first filter box 1 and a second filter box 2. Three sets of the first filter box 1 and the second filter box 2 are arranged end-to-end. A liquid outlet bend 3 is fixed to the bottom of each of the first filter box 1 and the second filter box 2. A one-way valve 4 is fixed to one end of each of the two liquid outlet bends 3, and a liquid outlet tee pipe 5 is fixed between the two one-way valves 4. A filtration mechanism 6 is provided at the top of each of the first filter box 1 and the second filter box 2 to ensure stability throughout the filtration cycle. The filtration mechanism 6 includes filter screens 601 respectively fitted into the top of the first filter box 1 and the second filter box 2. Three types of filter screens 601 are provided: a coarse filter screen, a fine filter screen, and an ultra-fine filter element. A mounting cover 602 is fixed to the top of each of the first filter box 1 and the second filter box 2 by bolts. An inlet valve is fixed to the top of each of the two mounting covers 602. The liquid inlet bend 603 has an inlet tee pipe 604 fixed at one end on one side and an electric valve 605 fixedly connected to the inlet tee pipe 604 at the other end on the other side. The inner wall of the inlet tee pipe 604 is integrally provided with a fixing ring 606. The water-based aluminum drawing liquid flows in from the inlet tee pipe 604 and then enters the first filter box 1 through the electric valve 605 and the inlet bend 603. The coarse filter screen removes large particulate impurities in the drawing liquid, the fine filter screen further filters smaller particulate impurities, and the ultrafine filter element performs final purification of the drawing liquid to ensure the purity of the liquid. Finally, the water-based aluminum drawing liquid flows out from the outlet bend 3 of the first filter box 1 and then flows to the next process through the one-way valve 4 and the outlet tee pipe 5. The box cover 602 can be installed and removed to facilitate the maintenance and replacement of the old filter screen 601.

[0033] like Figure 3 and Figure 4As shown, the filter mechanism 6 has an internal switching mechanism 7 that can automatically replace the filter screen with a spare screen. The switching mechanism 7 includes a mounting sleeve 701 fixed to one side wall of the inner cavity of the liquid inlet tee pipe 604. A telescopic sleeve 703 is slidably mounted on the outside of the mounting sleeve 701. A first sealing ring 702 is fixed to the outside of the mounting sleeve 701 and is sealed to the telescopic sleeve 703. A second sealing ring 704 is fixed to the outside of the telescopic sleeve 703 and is sealed to the outside of the telescopic sleeve 703 and is sealed to the fixed ring 606. A limit ring 705 is fixed to one end of the telescopic sleeve 703. A cylindrical spring 706 is fixed between the mounting sleeve 701 and the telescopic sleeve 703. A certain element is fixed to one side wall of the inner cavity of the mounting sleeve 701. The contact sensor 707 and the cylindrical spring 706 drive the telescopic sleeve 703 to extend through the mounting sleeve 701, so that the telescopic sleeve 703, together with the fixing ring 606, seals one end of the liquid inlet tee pipe 604. The limiting ring 705 prevents the telescopic sleeve 703 from separating. If the telescopic sleeve 703 is under too much pressure, it can be retracted through the mounting sleeve 701. In this way, the telescopic sleeve 703 no longer seals one end of the liquid inlet tee pipe 604. The water-based aluminum wire drawing liquid flows into the second filter box 2 for filtration through the liquid inlet tee pipe 604. After the telescopic sleeve 703 retracts, it will press the contact sensor 707, so that the contact sensor 707 drives the electric valve 605 to close.

[0034] In use, the water-based aluminum drawing liquid flows in through the inlet tee pipe 604, then enters the first filter box 1 through the electric valve 605 and the inlet bend pipe 603. A coarse filter removes large particles of impurities from the drawing liquid, a fine filter further filters smaller particles, and an ultrafine filter performs final purification to ensure liquid purity. Finally, the water-based aluminum drawing liquid flows out from the outlet bend pipe 3 of the first filter box 1, then flows to the next process through the one-way valve 4 and the outlet tee pipe 5. A cylindrical spring 706 drives the telescopic sleeve 703 to extend through the mounting sleeve 701, so that the telescopic sleeve 703, in conjunction with the fixing ring 606, seals one end of the inlet tee pipe 604. The limiting ring 7... 05. To prevent the telescopic sleeve 703 from separating, after the filter screen 601 in the first filter box 1 becomes clogged, the pressure on the telescopic sleeve 703 increases, causing the telescopic sleeve 703 to retract through the mounting sleeve 701. In this way, the telescopic sleeve 703 no longer blocks one end of the liquid inlet tee pipe 604, and the water-based aluminum wire drawing liquid flows into the second filter box 2 for filtration through the liquid inlet tee pipe 604. After the telescopic sleeve 703 retracts, it will press the contact sensor 707, causing the contact sensor 707 to drive the electric valve 605 to close, thereby blocking the other end of the liquid inlet tee pipe 604 and allowing the mounting box cover 602 to be disassembled and reassembled, thus facilitating the maintenance and replacement of the old filter screen 601.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
