Description

Technical Field

[0001] This utility model relates to the field of cement product processing and production technology, specifically a filtration and separation structure for the production of low-carbon modified liquid accelerators. Background Technology

[0002] "Cement products" refer to various building components or engineering materials made with cement as the main cementing material through molding, curing, and other processes. They are widely used in infrastructure fields such as construction, municipal works, transportation, water conservancy, and power. Low-carbon modified liquid quick-setting agent is a chemical admixture used in shotcrete (such as tunnels, mines, slope protection, etc.). Its main function is to rapidly solidify and harden the cement paste, thereby reducing rebound, improving construction efficiency, and increasing early strength.

[0003] Cement products require the addition of low-carbon modified liquid accelerators during processing. In the production of low-carbon modified liquid accelerators, it is necessary to remove small amounts of insoluble matter, dust, fibers, etc., introduced from the raw materials or generated during the reaction process to ensure product clarity and improve product appearance quality. Currently, the method for removing dust and impurities is usually to use cartridge filters for fine filtration. However, existing cartridge filters clog quickly during use, have a short lifespan, and require frequent replacement, increasing operating costs. Therefore, improvements are needed.

[0006] Preferably, the top of the filter cartridge is fixedly connected to a cover by bolts, and grooves are provided at the bottom of the cover and the top side of the filter cartridge. A sealing ring is placed inside the groove, and a liquid outlet pipe is connected to the top of the cover.

[0007] Preferably, a limiting frame is fixedly connected to the top side of the cover, and the limiting frame is symmetrically distributed about the bisector of the cover.

[0008] Preferably, one end of the push rod passes through the cover and the limiting frame and is located at the top of the limiting frame, and a sealing sleeve is provided between the push rod and the cover.

[0009] Preferably, a mounting bracket is fixedly connected to the top side of the limiting frame, and a drive wheel is rotatably connected to the inner side of the mounting bracket.

[0010] Preferably, a drive motor is fixedly connected to one end of the mounting bracket, and one end of the drive motor shaft is connected to the shaft at one end of the drive wheel.

[0011] Preferably, the mounting bracket, drive wheel, and drive motor are symmetrically distributed about the bisector of the limiting bracket, the inner side of the drive wheel is attached to the outer wall of the push rod, and the push rod and the cover are slidably connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) This device can prevent the filter element from clogging frequently, extend the service life of the filter element, and reduce the cost of using the filter element.

[0013] (2) This device uses a suction ring on the outer wall of the filter element. The suction ring can automatically rise and fall. The top side of the suction ring is connected to a suction pump and a drain pipe. Thus, while the suction ring is rising and falling, the suction force can be used to discharge more impurities adsorbed on the surface of the filter element from the drain pipe. This can avoid frequent clogging of the filter element and extend the service life of the filter element.

[0014] (3) This device uses a spiral inlet pipe fitted at the lower end of the filter element to transport the liquid around the filter element in a spiral shape, so that the liquid and the filter element can be in uniform contact for filtration, thus avoiding excessive clogging in a certain part of the filter element.

[0018] Please see Figure 1-5This utility model provides a technical solution: a filtration and separation structure for the production of low-carbon modified liquid quick-setting agent, including a filter cartridge 3, a base 12 fixedly connected to the bottom of the filter cartridge 3, and a cover 9 fixedly connected to the top of the filter cartridge 3 by bolts. Grooves are provided at the bottom of the cover 9 and on the top side of the filter cartridge 3, and a sealing ring 15 is placed inside the groove. A liquid outlet pipe 8 is connected to the top of the cover 9. The sealing ring 15 in this structure can ensure the sealing of the connection between the cover 9 and the filter cartridge 3. A limiting frame 2 is fixedly connected to the top side of the cover 9. The limiting frame 2 is symmetrically distributed about the bisector of the cover 9. The limiting frame 2 in this structure can limit the movement of the push rod 1, ensuring the stability of the push rod 1 during movement. The filter cartridge 3 has a filter element 4 inserted inside. A spiral inlet pipe 13 and a suction ring 19 are fitted onto the outer wall of the filter element 4. An inlet pipe 10 is connected to one side of the filter cartridge 3. The inlet pipe 10 is also driven by a pump; this part is existing technology and will not be described in detail here. One end of the inlet pipe 10 is connected to the spiral inlet pipe 13, and a magnetic column 11 is threaded onto the top of the inlet pipe 10. The magnetic column 11 can be detached from the top of the inlet pipe 10. The magnetic column 11 can adsorb metallic impurities in the liquid, facilitating cleaning. A solenoid valve 7 is also installed on the inlet pipe 10 to control its automatic opening and closing. A push rod 1 is connected to the top side of the suction ring 19. One side of the push rod 1... The end of the cover 9 and the limiting frame 2 are located at the top of the limiting frame 2. A sealing sleeve 14 is provided between the push rod 1 and the cover 9. The sealing sleeve 14 of this structure can ensure the sealing between the push rod 1 and the cover 9, and ensure the sealing of the filter cartridge 3 during operation. A mounting frame 17 is fixedly connected to the top side of the limiting frame 2. A drive wheel 16 is rotatably connected to the inner side of the mounting frame 17. This structure can ensure the stability of the drive wheel 16 during installation. A drive motor 18 is fixedly connected to one end of the mounting frame 17. One end of the shaft of the drive motor 18 is connected to the shaft of one end of the drive wheel 16. This structure has multiple drive wheels 16. The number of drive wheels 16 is set according to the actual situation. The mounting frame 17 Both the drive wheel 16 and the drive motor 18 are symmetrically distributed about the bisector of the limit frame 2. The inner side of the drive wheel 16 is tightly attached to the outer wall of the push rod 1. The push rod 1 and the cover 9 are slidably connected. The drive motor 18 of this structure can drive the drive wheel 16 to rotate automatically. The drive wheel 16 can use friction to push the push rod 1 to move by rotating, which makes it easy for the push rod 1 to slide on the cover 9. A drain pipe 6 is inserted inside the push rod 1. One end of the drain pipe 6 is connected to the suction ring 19. A suction pump 5 and a solenoid valve 7 are installed on the drain pipe 6. The suction ring 19 and the filter element 4 are slidably connected. The suction pump 5 and the solenoid valve 7 of this device are controlled by a PLC.

[0019] Working principle: When using the filtration and separation structure for the production of this low-carbon modified liquid quick-setting agent, the liquid first enters the spiral inlet pipe 13 from the inlet pipe 10. Then, under the action of the spiral inlet pipe 13, the liquid moves spirally from bottom to top around the filter element 4. During the liquid transportation process, it contacts the filter element 4 for filtration and separation. The separated impurities remain on the outer wall of the filter element 4, while the liquid is discharged from the outlet pipe 8. When cleaning the filter element 4, the drive motor 18 drives the drive wheel 16 to rotate automatically. Under the action of friction, the drive wheel 16 pushes the push rod 1 downward, causing the push rod 1 to push the suction ring 19 to move from top to bottom on the outer wall of the filter element 4. During the movement, under the action of the suction pump 5 and the solenoid valve 7, the impurities on the surface of the filter element 4 can be adsorbed and discharged from the drain pipe 6, thereby improving the service life of the filter element 4.
