Description

Technical Field

[0001] This utility model relates to the field of aluminum rolling technology, specifically to a screen structure for preventing clogging of the filter valve in a mixing tank. Background Technology

[0002] In the aluminum rolling process, rolling oil is recycled as a coolant and lubricant. The recycled rolling oil carries aluminum ash impurities generated by friction between the rolls and the aluminum material. To remove this aluminum ash and improve the purity and recycling rate of the rolling oil, the industry commonly employs a process of adding adsorbents (such as diatomaceous earth or clay) to the rolling oil in a mixing tank (or mixing vessel). These adsorbents effectively adsorb the aluminum ash in the rolling oil, and then a suction pump transports the oil and adsorbent mixture to a plate filter. In the plate filter, the diatomaceous earth and clay that have adsorbed the aluminum ash are trapped by the filter paper and form a filter cake, while the clean rolling oil is recycled through the filter paper.

[0003] However, the existing production process has a significant drawback: the diatomaceous earth and clay used as raw materials may contain large, insoluble impurities such as fibers, plastic flakes, and lumps during production and transportation. When these impurities are added to the mixing tank, they will directly enter the tank. Since the valve core channel of the suction valve is usually quite precise, these large impurities are very easy to accumulate at the valve core, which will cause the suction valve to become blocked. Once a blockage occurs, the machine must be stopped and the mixing tank and valve must be disassembled and cleaned, which will greatly reduce work efficiency and make it inconvenient to use. Utility Model Content

By setting a double-layer filter structure with the upper screen hole being larger than the lower screen hole, gradient filtration of incoming materials is achieved, ensuring that only fine particles that meet the requirements can enter the main chamber of the mixing tank. It can effectively intercept large foreign objects that may cause valve core clogging, thereby avoiding valve core clogging, helping to improve work efficiency, and is easy to use. It can effectively solve the problems in the background art.

[0009] As a preferred embodiment of this utility model, the upper end of the inner side of the annular card plate is provided with an annular baffle, and the upper screen is placed on the annular baffle.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3This utility model provides a technical solution: a screen structure for preventing clogging of the filter valve of a mixing tank, including an annular plate 1 movably installed at the feed inlet of the mixing tank 7, a lower screen 2 provided at the bottom of the annular plate 1, and an upper screen 4 installed at the upper end of the inner side of the annular plate 1, and a through hole with the same size as the upper screen hole of the lower screen 2 opened at the lower end of the peripheral side of the annular plate 1, and a funnel 5 installed on the upper surface of the annular plate 1, the funnel 5 being used to guide the material and facilitate the material to pass through the screen for filtration.

[0015] Furthermore, a bearing 71 is provided on the upper surface of the feed inlet of the mixing tank 7, and an annular clamping plate 1 is movably inserted into the inner ring of the bearing 71.

[0016] Furthermore, the side of the mixing tank 7 is provided with a driving component that drives the annular plate 1 to swing back and forth.

[0017] Furthermore, the driving component includes a servo motor 8 mounted on the upper side of the mixing tank 7. A driving disk 81 is mounted on the output shaft of the servo motor 8. A connecting rod 82 is rotatably mounted on an eccentric column on the upper surface of the driving disk 81. A locking post 83 is located at the end of the connecting rod 82 away from the driving disk 81. An ear plate 6 is located on the side of the annular locking plate 1, and the locking post 83 is movably inserted into the ear plate 6. The servo motor 8 drives the driving disk 81 to rotate, and the driving disk 81 drives the annular locking plate 1 to reciprocate within a certain angle via the connecting rod 82. The annular locking plate 1 drives the funnel 5 and the lower screen 2 to reciprocate. The upper screen 4 and the lower screen 2 perform secondary filtration of the raw materials, preventing large particles of impurities from clogging the valve core of the suction valve on the mixing tank 7. Simultaneously, it ensures that the material on the lower screen 2 can dissolve into the rolling oil.

[0018] The eccentric drive unit can drive the screen to rotate back and forth. The oscillation of the screen can effectively disturb the raw materials and impurities on its surface, preventing impurities from accumulating and caking on the screen surface, ensuring the continuous unobstructed flow of the filtration channel, avoiding the problem of easy clogging of traditional static screens, and greatly reducing the maintenance frequency.

[0019] Furthermore, an annular baffle 3 is provided on the upper inner side of the annular plate 1, and the upper screen 4 is placed on the annular baffle 3, which facilitates the removal of the upper screen 4 and thus facilitates the cleaning of impurities between the upper screen 4 and the lower screen 2.

[0020] Under the shearing and stirring action of the reciprocating rotation of the screen, it can be dissolved and dispersed into the rolling oil more quickly and evenly. This not only improves the utilization rate of diatomaceous earth and white clay, allowing their adsorption capacity to be fully utilized, but also makes the oil-soil mixture more uniform, which is conducive to the formation of a stable and permeable filter cake on the plate filter in the subsequent process.

[0021] The servo motor 8 used in this utility model is a commonly used electronic component in the prior art. Its working method and circuit structure are well-known technologies and will not be described in detail here.

[0022] When using: Insert the annular plate 1 into the feed inlet of the mixing tank 7, and then pour the diatomaceous earth and white clay raw materials into the funnel 5; The rolling oil enters the mixing tank 7 through the oil inlet pipe on the mixing tank 7, and the rolling oil is kept submerged in the lower screen 2; The servo motor 8 is controlled to operate, driving the drive disk 81 to rotate. The drive disk 81, through the connecting rod 82, drives the annular clamping plate 1 to reciprocate within a certain angle. The annular clamping plate 1 drives the funnel 5 and the lower screen 2 to reciprocate. The upper screen 4 and the lower screen 2 perform secondary filtration of the raw materials to prevent large particles of impurities from clogging the valve core of the suction valve on the mixing tank 7. At the same time, it ensures that the material on the lower screen 2 can be dissolved into the rolling oil.

[0023] This invention achieves gradient filtration of incoming materials by setting a double-layer filter structure with the upper sieve hole being larger than the lower sieve hole. This ensures that only fine particles that meet the requirements can enter the main chamber of the mixing tank, effectively intercepting large foreign objects that may cause valve core blockage, thereby avoiding valve core blockage, improving work efficiency, and making it convenient to use.
