Description

Technical Field

[0001] This utility model relates to the field of aluminum rod production technology, and in particular to an emulsion filtration device. Background Technology

[0002] The use of emulsion is an important step in the cooling and rolling process of molten aluminum. It plays a role in cooling, lubrication and cleaning, which can prevent defects such as scratches and cracks on the surface of aluminum materials, improve the surface finish of products, and absorb and remove a large amount of heat to prevent tools and aluminum materials from being damaged by overheating. It can improve the processing efficiency and quality of aluminum bars. Therefore, the management of emulsion is crucial to product quality and production efficiency.

[0003] Filtration of emulsions is a crucial step in ensuring their stable performance and extending their service life. In the past, filtration was usually simple, and when the emulsions failed to meet standards, they were handed over to a third party for treatment. However, this process was complicated and prone to leakage. Current filtration equipment is not only expensive but also has high maintenance costs. To address this, we have proposed an emulsion filtration device that utilizes factory conditions to reduce equipment and maintenance costs while performing filtration. Utility Model Content

[0004] This application provides an emulsion filtration device that solves the problem of high cost in traditional emulsion filtration.

[0005] This application provides an emulsion filtration device, including a filter box, a blind plate on one side of the filter box, the filter box being pressurized by an external pressurization system, a mounting flange on the top of the filter box, a filter pipe being installed on the mounting flange via a connecting flange, a liquid outlet pipe on the top of the connecting flange, the liquid outlet pipe being connected to an external collection system, and a drain pipe at the bottom of the filter box.

[0006] It also includes a pretreatment feeding structure connected to the filter box.

[0007] Preferably, the filter tube includes a connecting tube and a first filter screen, wherein the first filter screen is located at the bottom.

[0008] Preferably, the pretreatment feeding structure includes a pretreatment tank, a second filter screen is provided inside the pretreatment tank, the bottom of the pretreatment tank is connected to the filter box through an infusion pipe, and a solenoid valve is provided on the infusion pipe.

[0009] Preferably, a hook is provided at the edge of the pretreatment tank, and the second filter screen is suspended on the hook.

[0010] Preferably, a pressurized connecting pipe is installed on one side of the filter box, and the pressurized connecting pipe is connected to the external pressurization system.

[0011] Preferably, the filter box is also equipped with a level gauge and an electronic pressure relief valve.

[0012] Preferably, the level gauge is installed on the side away from the pretreatment feeding structure.

[0013] Preferably, the mounting flange is provided with studs, and the connecting flange is mounted on the mounting flange by means of studs.

[0014] As can be seen from the above technical solution, this application provides an emulsion filtration device. After the used emulsion is pretreated by the pretreatment feeding structure, it is sent to the filter box. When the liquid level in the filter box reaches a certain height, the external pressurization system is activated to pressurize the filter box to 3-15 standard atmospheres. Under the action of pressure, the emulsion in the filter box is filtered from the filter tube and flows to the external collection system for collection through the liquid outlet pipe. When the liquid outlet volume is greater than the set value or the liquid level is lower than the set value, the filter box is controlled to normal pressure. At this time, the emulsion in the filter tube flows back to flush the filter tube. At the same time, the emulsion to be filtered is injected into the filter box again, and the above steps are repeated for filtration. After filtration several times, the emulsion in the filter box is discharged, the blind plate is removed to clean the sediment at the bottom of the filter box, and the filter tube can also be removed for cleaning.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up the filter box and blind plate, the filtered residue first settles at the bottom, and is cleaned after multiple filtrations, which can ensure the smoothness of filtration.

[0017] 2. By setting up the filter tube, filtration is carried out by external pressure. Static sedimentation is performed first, followed by filtration. Each filtration is cleaned by recirculation, which improves filtration efficiency. In addition, the pressurization can be completed in one go in this application, without continuous work. The equipment in the factory can be used directly.

[0018] 3. By setting up a pre-treatment feeding structure, the emulsion entering the filter box is subjected to basic filtration, reducing impurities and further improving filtration efficiency.

[0019] In summary, this application can perform filtration by pressure, and the filtration efficiency can be adjusted according to the installed filter tube. It has high filtration efficiency, simple equipment, easy disassembly and maintenance, and low production and maintenance costs. It can meet the needs of uninterrupted filtration in the plant area, ensuring that the emulsion after cooling aluminum rods can be directly put into this application for filtration.

[0026] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] See Figure 1-4 This application discloses an emulsion filtration device for filtering emulsions generated during aluminum rod processing. Specifically, it includes a filter box 1, which is a rectangular filter box, readily available, inexpensive, and easily modifiable. A blind plate 2 is provided on one side of the filter box 1, fixed to it with screws. The sediment at the bottom of the filter box 1 can be cleaned by removing the blind plate 2. It is important to note that the filter box 1 should be thoroughly cleaned before prolonged periods of non-use to prevent the emulsion from becoming moldy and deteriorating. The filter box 1 is pressurized by an external pressurization system. Specifically, a pressurization connection pipe 5 is installed on one side of the filter box 1, connected to an external pressurization system. The device can be pressurized using an air compressor or other pressurization equipment. During filtration, the pressure inside the filter box 1 can be adjusted according to the filtration efficiency. Under the same filtration conditions, higher pressure results in higher filtration efficiency. The optimal filtration conditions are 3-15 standard atmospheres, allowing for rapid filtration.

[0028] During filtration, a mounting flange 7 is provided on the top of the filter box 1. The mounting flange 7 has mounting holes, and a filter tube is installed on the mounting flange 7 through a connecting flange 10. The mounting flange 7 is provided with studs 6, and the connecting flange 10 is installed on the mounting flange 7 through the studs 6. The installation is quick and the sealing is good. The filter tube extends into the filter box 1. In actual use, multiple mounting flanges 7 can be used to install filter tubes of different specifications and quantities according to specific needs. The more filter tubes installed, the higher the filtration efficiency. The mounting flanges 7 in other positions can be blocked by flange blind plates. A liquid outlet pipe 11 is provided on the top of the connecting flange 10. After the internal of the filter box 1 is pressurized, the emulsion inside is filtered through the filter tube and discharged from the liquid outlet pipe 11. The liquid outlet pipe 11 is connected to the external collection system. In use, the liquid outlet pipe 11 needs to be connected to the emulsion collection tank through a pipeline. A drain pipe 15 is also provided at the bottom of the filter box 1. When it is necessary to clean the filter box 1, all the liquid inside can be discharged through the drain pipe 15 before cleaning.

[0029] This application also includes a pretreatment feeding structure connected to the filter box 1, which performs initial filtration on the emulsion entering the filter box 1 to remove larger impurities, thereby reducing clogging of the filter tube and further improving filtration efficiency.

[0030] In some embodiments, the emulsion in the pretreatment feeding structure can be pumped to the filter box 1 to achieve continuous filtration. This embodiment is suitable for filtering the emulsion of cooling aluminum rods. The filtration accuracy is not high, so the filtration density requirement of the filter tube is not high. Filtration can be completed with a pressure of 3-5 standard atmospheres and the filtration efficiency is high.

[0031] In some embodiments, the emulsifier in the pretreatment feeding structure is fed into the filter box 1 under normal pressure, and then the pipeline is closed and pressure is applied to the filter box 1 to filter the emulsion. This embodiment is used to filter the emulsion in the rolling process, so the filtration requirements are high. The pressure of 5-15 standard atmospheres can be used for filtration. After each filtration, the filter box 1 is restored to normal pressure, and the emulsion in the filter tube flows back into the filter box 1 to clean the filter tube for the next filtration.

[0032] In this application, the filter tube includes a connecting pipe 9 and a first filter screen 8, wherein the first filter screen 8 is located at the bottom. During filtration, filtration is mainly carried out through the first filter screen 8. Therefore, when the emulsion is injected into the filter box 1, it can be injected to 2 / 3 of the height of the connecting pipe 9. When pressurized, the pressure inside the filter box 1 can be guaranteed. The connection position between the connecting pipe 9 and the first filter screen 8 is the lowest position of the emulsion.

[0033] In this application, the pretreatment feeding structure includes a pretreatment tank 12, which can be an open tank. A second filter screen 16 is installed inside the pretreatment tank 12 to perform initial filtration of the emulsion. The bottom of the pretreatment tank 12 is connected to the filter box 1 through a liquid delivery pipe 13. A solenoid valve 14 is installed on the liquid delivery pipe 13 to control the connection between the filter box 1 and the pretreatment tank 12. It should be understood that the emulsion in the pretreatment tank 12 is pumped into the filter box 1.

[0034] Furthermore, a hook 17 is provided at the edge of the pretreatment tank 12, and the second filter screen 16 can be quickly installed and removed from the pretreatment tank 12. Therefore, the second filter screen 16 is suspended on the hook 17, and when there is a lot of filter material on the upper layer of the second filter screen 16, it can be quickly replaced.

[0035] In this application, in order to more accurately detect the information inside the filter box 1, a level gauge 3 and an electronic pressure relief valve 4 are also installed on the filter box 1. The level gauge 3 is used to detect the pressure inside the filter box 1, and the electronic pressure relief valve 4 is used to quickly release the pressure inside the filter box 1 to normal pressure, thereby controlling the pressure inside the filter box 1.

[0036] Furthermore, the level gauge 3 is installed on the side away from the pretreatment feeding structure. When the emulsion flows to the level gauge 3, the liquid level is stable, avoiding the influence of the pretreatment feeding structure on the level gauge 3 and causing liquid level measurement error.

[0037] As can be seen from the above technical solution, the used emulsion is pretreated by the pretreatment feeding structure and then sent to the filter box 1. When the liquid level in the filter box 1 reaches a certain height, the external pressurization system is activated to pressurize the filter box 1 to 10-15 standard atmospheres. Under the action of pressure, the emulsion in the filter box 1 is filtered from the filter tube and flows to the external collection system through the liquid outlet pipe 11 for collection. When the liquid outlet volume is greater than the set value or the liquid level is lower than the set value, the filter box 1 is controlled to normal pressure. At this time, the emulsion in the filter tube flows back to flush the filter tube. At the same time, the emulsion to be filtered is injected into the filter box 1 again, and the above steps are repeated for filtration. After filtration several times, the emulsion in the filter box 1 is discharged, the blind plate 2 is removed to clean the sediment at the bottom of the filter box 1, and the filter tube can also be removed for cleaning.

[0038] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope of this application is indicated by the claims.

[0039] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The embodiments of this application described above do not constitute a limitation on the scope of protection of this application.
