Description

Technical Field

[0001] This utility model relates to the field of liquid cement grinding aids, and more specifically, to a liquid cement grinding aid filtration device. Background Technology

[0002] Liquid cement grinding aid is a composite additive composed of various chemical substances, such as polycarboxylate superplasticizer, silicate cement, polyol, ethylenediaminetetraethanol, and hydroxyethyl cellulose. Through physicochemical action, it can significantly improve the grinding efficiency of cement mills, increase cement production, and simultaneously reduce energy consumption and production costs.

[0003] In the production process of cement mills, liquid grinding aids are widely used to optimize grinding efficiency and improve cement quality. However, due to the various tiny impurities that liquid grinding aids may contain, such as suspended particles, precipitates, or incompletely dissolved chemical components, these impurities tend to accumulate in the conveying pipes and nozzles, leading to pipe blockage and nozzle clogging. This not only affects the continuity and stability of cement production, but may also lead to equipment failure and reduced production efficiency.

[0004] Therefore, we have made improvements to this by proposing a liquid cement grinding aid filtration device. Utility Model Content

[0032] To address the technical problems in the background section, the following liquid cement grinding aid filtration device is provided:

[0033] Combination Figure 1 - Figure 5 As shown, the present invention provides a liquid cement grinding aid filtration device, including a conveying pipe 1, a Y-type filter 2 threadedly connected to the middle of the conveying pipe 1, and the Y-type filter 2 including an inclined tube 3, a mounting cover 4 provided on one side surface of the inclined tube 3, and a handle 5 fixedly installed on the surface of the mounting cover 4, a filtration mechanism 6 provided inside the inclined tube 3, and a connecting mechanism 7 provided between the mounting cover 4 and the inclined tube 3; the filtration mechanism 6 includes a baffle 601, and the baffle 601 is fixedly installed inside the Y-type filter 2, and a water flow hole 602 is opened on the surface of the baffle 601; a filter screen cylinder 603 is provided inside the inclined tube 3, and a fixing ring 604 is fixedly installed on both ends of the filter screen cylinder 603.

[0034] In this embodiment: the middle of the conveying pipe 1 is threadedly connected to the Y-type filter 2. The main structure of the Y-type filter 2 is composed of an inclined tube 3. An installation cover 4 is designed on one side of the inclined tube 3. An easy-to-operate handle 5 is fixedly installed on the installation cover 4, which is convenient for users to open or close easily. The inclined tube 3 is equipped with a filter mechanism 6. This mechanism consists of a baffle 601 fixedly installed inside the Y-type filter 2. The baffle 601 has evenly spaced water flow holes 602 to ensure that the liquid grinding aid can flow evenly. The inclined tube 3 is also equipped with a detachable filter screen cylinder 603. Its two ends are firmly installed inside the inclined tube 3 by fixing rings 604, thereby effectively intercepting and filtering out the tiny impurities in the liquid grinding aid, ensuring that the grinding aid entering the cement mill is pure and free of dirt.

[0035] refer to Figure 2 - Figure 4Based on the above embodiments, in order to connect the filter cylinder 603, this embodiment provides the following design:

[0036] In a preferred embodiment, a plurality of protrusions 605 are fixedly installed on one side surface of the fixing ring 604 at the lower end of the filter cylinder 603, and a plurality of mounting holes 606 are opened on one side surface of the mounting cover 4, and the protrusions 605 and the mounting holes 606 are connected by a snap-fit ​​connection.

[0037] In this embodiment, several protrusions 605 are installed on one side surface of the fixing ring 604 at the lower end of the filter cylinder 603. These protrusions 605 are engaged with the mounting holes 606 pre-drilled on one side surface of the mounting cover 4. At the same time, the fixing ring 604 on the upper side will contact the baffle 601 to improve the sealing of both ends of the filter cylinder 603. This makes the installation and removal of the filter cylinder 603 simple and convenient for users to clean or replace the filter cylinder 603 regularly.

[0038] refer to Figure 1 - Figure 4 Based on the above embodiments, in order to clean the filter cylinder 603 and prevent it from becoming clogged, thus affecting the flow of the grinding aid, this embodiment provides the following design:

[0039] In a preferred embodiment, a motor 607 is fixedly mounted on the lower surface of the mounting cover 4, and a connecting block 608 is fixedly connected to the output end of the motor 607. The connecting block 608 is rotatably connected to the other side surface of the mounting cover 4. A cleaning brush 609 is fixedly mounted on one side surface of the connecting block 608, and the cleaning brush 609 is in contact with the inner wall of the filter cylinder 603.

[0040] In this embodiment: the cleaning brush 609 is in close contact with the inner wall of the filter cylinder 603. As the motor 607 is started, the connecting block 608 and the cleaning brush 609 will rotate, thereby effectively cleaning the residual impurities on the inner wall of the filter cylinder 603. The cleaned impurities will fall to the bottom of the filter cylinder 603, which will not affect the normal flow of the grinding aid and also facilitates the centralized treatment of the filtered impurities.

[0041] refer to Figure 1 - Figure 5 Based on the above embodiments, in order to facilitate the connection of the mounting cover 4, this embodiment provides the following design:

[0042] In a preferred embodiment, the connecting mechanism 7 includes a mounting block 701, and two mounting blocks 701 are provided. Both mounting blocks 701 are fixedly mounted on one side surface of the mounting cover 4. Two mounting grooves 702 are opened on one side surface of the inclined tube 3, and a slot 703 is opened on one side surface of the mounting groove 702. The mounting block 701 and the mounting groove 702 are engaged and connected.

[0043] In this embodiment: two mounting blocks 701 are fixedly mounted on one side surface of the mounting cover 4. Two matching mounting grooves 702 are opened on one side surface of the inclined tube 3, and a slot 703 is located on one side of the mounting groove 702. During the installation process, the mounting blocks 701 can be easily inserted into the mounting grooves 702, which makes it easy to connect the mounting cover 4 to one side surface of the inclined tube 3.

[0045] In a preferred embodiment, a slot 704 is provided on one side surface of the mounting block 701, and a locking block 705 is slidably connected inside the slot 704. The locking block 705 is engaged with the slot 703, and one side surface of the locking block 705 is inclined. A spring 706 is fixedly installed between the locking block 705 and the inner wall of the slot 704.

[0046] In this embodiment, a slot 704 is cleverly provided on one side surface of the mounting block 701. A self-resetting locking block 705 is slidably connected inside the slot 704. One side surface of the locking block 705 is inclined. When the mounting cover 4 is connected to the inclined tube 3, the locking block 705 can automatically retract inward as the mounting block 701 enters the mounting slot 702. After reaching the position of the locking slot 703, the locking block 705 is quickly ejected under the elastic force of the spring 706, forming a stable locking connection with the locking slot 703. This not only ensures that the connection between the mounting cover 4 and the inclined tube 3 is both quick and stable, but also allows the user to easily separate the mounting cover 4 by simply applying a little external force to retract the locking block 705 inward without it locking with the locking slot 703. This greatly improves the convenience of operation and the practicality of the device, making it easier to clean the collected impurities.
