Description

Technical Field

[0001] This utility model relates to a mixed-type zirconium oxide raw material iron removal filter, belonging to the technical field of filtration devices. Background Technology

[0002] In the production of zirconia ceramics, ferromagnetic impurities in the raw materials (such as iron filings and iron powder) can severely affect the performance and quality of the product. The presence of iron not only causes zirconia ceramics to turn yellow or black, affecting their appearance, but also reduces the dielectric properties of the ceramics, significantly impacting the breakdown strength, insulation resistance, and withstand voltage of electronic ceramics. Therefore, iron removal is a crucial step in the processing of zirconia raw materials.

[0003] Currently, iron removal methods for zirconia raw materials mainly include physical and chemical methods. Physical iron removal primarily utilizes the attraction of a magnetic field to remove ferromagnetic impurities from the raw material, offering advantages such as environmental friendliness and high efficiency. However, traditional physical iron removal equipment often suffers from cumbersome operation and low efficiency when cleaning iron impurities adsorbed on magnetic rods. When the surface of the magnetic rod is saturated with iron impurities, it not only affects its ability to continue adsorbing and filtering iron impurities but also increases fluid resistance within the cylinder, reducing filtration efficiency. Furthermore, some equipment also suffers from difficulties in cleaning the iron removal medium and its tendency to accumulate, leading to a decrease in filtration efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a zirconia raw material iron removal filter, which aims to improve the iron filings removal efficiency by optimizing the equipment structure and cleaning method, while reducing maintenance time costs and operation difficulty.

[0005] The present invention relates to a zirconia raw material iron removal filter for collecting impurities, comprising a filter cylinder with a fluid inlet and a fluid outlet, and several magnetic rods inside the filter cylinder. The top ends of the magnetic rods are fixed to a cover plate, and an upper end cover is fixed to the top port of the filter cylinder. The magnetic rods pass through the upper end cover and are inserted into the filter cylinder. The cover plate is located on the upper end cover and is fixed by fasteners. After the fasteners are released, the cover plate can be pulled upward along with the magnetic rods. The bottom port of the filter cylinder is connected to a collection cylinder, and a gate valve is provided between the collection cylinder and the filter cylinder.

[0006] When zirconia fluid containing ferromagnetic impurities flows through the filter cartridge, the strong magnetic field of the magnetic rod attracts and firmly adsorbs these iron filings, iron powder, and other impurities, preventing them from continuing to flow with the fluid, thus filtering out iron impurities. After a period of use, when the surface of the magnetic rod is covered with iron impurities, it will affect the continued adsorption and filtration of iron impurities, and will also increase the fluid resistance inside the cartridge. At this time, simply empty the fluid in the filter cartridge, open the gate valve, release the fasteners from the end cap, and pull up the cover plate. The iron filings adsorbed on the magnetic rod will be scraped off by the cover plate and fall into the collection cylinder. After scraping, the gate valve closes, and the fluid passes through the filter cartridge normally for adsorption and filtration. When a certain amount of iron filings accumulates in the collection cylinder, they are collected and processed. Iron filings cleaning is quick and convenient, and does not require frequent cleaning.

[0007] Preferably, a sealing sleeve is provided at the sliding connection between the magnetic rod and the upper end cover, and the sealing sleeve is fixedly installed on the bottom surface of the upper end cover.

[0008] Preferably, the lower end of the filter cartridge is provided with a drain port, through which the fluid inside the filter cartridge can be drained.

[0009] The bottom of the collection cylinder of this utility model is provided with a detachable lower end cover.

[0010] Preferably, the cover plate is provided with a lifting handle.

[0011] Preferably, the fastener is a claw.

[0012] The advantages of this utility model compared with the prior art are:

[0013] 1. Simple cleaning method: When the surface of the magnetic rod is covered with iron impurities, simply drain the fluid from the filter cartridge, open the gate valve, release the fasteners from the end cover, and pull the cover upwards to scrape off the iron impurities adsorbed on the magnetic rod and let them fall into the collection cylinder. This cleaning method is simple and quick, greatly reducing maintenance time and operational difficulty.

[0014] 2. Centralized collection and treatment of iron impurities: The design of the impurity collection cylinder allows the scraped iron impurities to be collected in the collection chamber, eliminating the need for frequent cleaning and facilitating subsequent centralized treatment and recycling, thus reducing environmental pollution and resource waste.

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] The description of this utility model is merely a structural or even functional description of the embodiments, and the scope of this utility model is not limited by the embodiments described herein.

[0020] like Figure 1 , 2 As shown, this embodiment is achieved through the following technical solution: a mixed-type zirconia raw material iron removal filter, including a filter cylinder 7, a fluid inlet 8 and a fluid outlet 13 on the filter cylinder 7, a plurality of magnetic rods 3 inside the filter cylinder 7, the top of the magnetic rods 3 being fixed on a cover plate 5, and an upper end cover 1 being fixed to the top port of the filter cylinder 7 by a stud 6, and the magnetic rods 3 passing through the upper end cover 1 and being placed inside the filter cylinder 7.

[0021] The cover plate 5 is located above the upper cover 1 and is fixed by a pawl 14. The pawl 14 is rotatably mounted on the stud 6. After the pawl 14 rotates to release the fixation, the cover plate 5, together with the magnetic rod 3, can be pulled upwards. Figure 2 As shown, the cover plate 5 is equipped with a lifting handle 4.

[0022] In this embodiment, the bottom port of the filter cartridge 7 is connected to the collection cartridge 10, and the bottom of the collection cartridge 10 is provided with a detachable lower end cover 11. A gate valve 9 is provided between the collection cartridge 10 and the filter cartridge 7.

[0023] In this embodiment, a sealing sleeve 2 is provided at the sliding connection between the magnetic rod 3 and the upper end cover 1, and the sealing sleeve 2 is fixedly installed on the bottom surface of the upper end cover 1.

[0024] In this embodiment, the filter cartridge 7 is provided with a drain outlet 15 at its lower end.

[0025] The working principle of this utility model:

[0026] When the zirconia fluid containing ferromagnetic impurities flows through the inside of the filter cartridge 7, the strong magnetic field of the magnetic rod will attract and firmly adsorb these iron filings, iron powders and other impurities, preventing them from continuing to flow with the fluid, thereby playing the role of filtering iron impurities.

[0027] After a period of use, when the surface of the magnetic rod 3 becomes covered with iron impurities, it will affect the effect of continuing to adsorb and filter iron impurities, and will also increase the fluid resistance inside the cylinder. At this time, simply open the drain port 15 to drain the fluid inside the filter cylinder 7, open the gate valve 9, release the fixing effect of the claw 14 on the cover plate 5, and lift the cover plate 5 upward by pulling the handle 4. The iron filings adsorbed on the magnetic rod 3 will be scraped off by the sealing sleeve 2 and fall into the impurity collection chamber 12.

[0028] After scraping is complete, the drain port 15 and the gate valve 9 are closed, and the fluid passes normally through the filter cylinder 7 for adsorption and filtration. When a certain amount of iron filings accumulates in the collection cylinder 10, the lower end cover 11 is opened for centralized collection and treatment. Iron filings cleaning is quick and convenient, and does not require frequent cleaning.

[0029] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
