Technical Field
[0001] This utility model relates to the field of cement-based self-leveling mortar raw material mixing and filtration, specifically a filter structure for mixing cement-based self-leveling mortar raw materials. Background Technology
[0002] Cement-based self-leveling mortar is a flooring material made by mixing cement as the base material with fine aggregates and additives in a certain proportion. It has good flow properties and can automatically level itself. After being mixed with water, it can automatically flow and distribute evenly on the ground, thereby achieving high-precision leveling of the ground. This makes the construction process more convenient and greatly improves the efficiency of use. When using cement-based self-leveling mortar, it is necessary to filter the mixed cement-based self-leveling mortar to avoid excessive impurities affecting the forming effect of the self-leveling floor.
[0003] Currently, the filtration of cement-based self-leveling mortar mainly occurs during the discharge process. However, when the discharge volume is too large, larger particles tend to accumulate on the filter screen, causing clogging and affecting the discharge effect. Furthermore, the large particles filtered out are inconvenient to recycle, which easily leads to resource waste. Therefore, a filter structure for mixing cement-based self-leveling mortar raw materials is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology and address the problems existing in the existing technology, this utility model proposes a filter structure for mixing cement-based self-leveling mortar raw materials.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a filter structure for mixing cement-based self-leveling mortar raw materials, comprising a mixing bucket; multiple sets of filter components are arranged vertically inside the mixing bucket, and the pore diameter of the filter holes in the multiple sets of filter components gradually decreases from top to bottom; The mixing drum is connected to a stirring shaft, which is connected to multiple stirring shafts. A fixed grinding disc is installed at the top inside the mixing drum. A material leakage port is provided on the fixed grinding disc. A rotating grinding disc is rotatably fitted onto the lower surface of the fixed grinding disc. A circulation pipe is installed at the bottom of the mixing tank. The end of the circulation pipe is bent and connected to the top of the mixing tank. The outlet at the upper end of the circulation pipe is located at the opening of the leakage port.
[0006] Preferably, the fixed grinding disc is rotatably mounted on the side wall of the mixing tank and located outside the stirring shaft, and the stirring shaft is connected to the rotating grinding disc through a fixed rod.
[0007] Preferably, a conveying pump is installed on the circulation pipe, and a discharge pipe connected to the bottom bend of the circulation pipe is provided therewith, and a sealing valve for sealing is installed on the discharge pipe.
[0008] Preferably, the filter assembly includes a V-shaped filter plate and a connecting rod. The V-shaped filter plate is fixed to the inner wall of the mixing tank and located outside the stirring shaft. The connecting rod is fixed to the stirring shaft. The V-shaped filter plate is provided with filter holes.
[0009] Preferably, a rolling wheel is rotatably mounted on the end of the connecting rod, and the rolling wheel is rolled in the V-shaped groove of the V-shaped filter plate. A scraper is fixedly connected to the connecting rod, and the movement trajectory of the scraper is located on the upper surface of the V-shaped filter plate.
[0010] Preferably, a second scraper is fixedly connected to the bottom end of the stirring shaft, and the rotation trajectory of the second scraper is located on the bottom surface of the mixing barrel. A motor for driving the stirring shaft is installed on the mixing barrel through a fixing component.
[0011] Preferably, a feeding port is provided on the side wall of the mixing barrel, and a support bracket is installed on the outer wall of the mixing barrel for support.
[0012] The advantages of this utility model are: This invention utilizes a V-shaped filter plate where larger particles are retained. Under the rolling action of a grinding wheel, these larger particles within the V-shaped grooves are crushed. Particles matching the filter pore size then leak downwards. Multiple sets of filter components further crush the larger particles, mixing them with the mortar raw materials for use. The raw materials, after exiting from the outlet of the circulation pipe, enter the leakage port, where a rotating grinding disc further grinds and crushes them, further breaking down the larger particles. This ensures the fluidity of the cement-based self-leveling mortar and improves the mixing effect of the mortar raw materials.

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 scope of protection of the present utility model.
[0016] Please see Figure 1-4 As shown, a filter structure for mixing cement-based self-leveling mortar raw materials includes a mixing tank 1; multiple sets of filter components 42 are arranged vertically inside the mixing tank 1, and the pore size of the filter holes in the multiple sets of filter components 42 gradually decreases from top to bottom. The mixing tank 1 is connected to a stirring shaft 41, which is connected to multiple sets of stirring shafts 41. A fixed grinding disc 44 is installed at the top inside the mixing tank 1. A material leakage port 45 is provided on the fixed grinding disc 44. A rotating grinding disc 46 is rotatably attached to the lower surface of the fixed grinding disc 44. A circulation pipe 5 is installed at the bottom of the mixing tank 1. The end of the circulation pipe 5 is bent and connected to the top of the mixing tank 1. The outlet at the upper end of the circulation pipe 5 is located at the opening of the leakage port 45.
[0017] The fixed grinding disc 44 is rotatably mounted on the side wall of the mixing tank 1 and located outside the stirring shaft 41. The stirring shaft 41 is connected to the rotating grinding disc 46 through a fixing rod 47.
[0018] A conveying pump 6 is installed on the circulation pipe 5, and a discharge pipe 7 connected to the bottom bend of the circulation pipe 5 is provided therewith. A sealing valve 8 for sealing is installed on the discharge pipe 7.
[0019] The filter assembly 42 includes a V-shaped filter plate 421 and a connecting rod 422. The V-shaped filter plate 421 is fixed to the inner wall of the mixing tank 1 and located outside the stirring shaft 41. The connecting rod 422 is fixed to the stirring shaft 41. The V-shaped filter plate 421 is provided with filter holes.
[0020] A rolling wheel 423 is rotatably mounted on the end of the connecting rod 422. The rolling wheel 423 is rolled in the V-shaped groove of the V-shaped filter plate 421. A scraper 424 is fixedly connected to the connecting rod 422. The movement trajectory of the scraper 424 is located on the upper surface of the V-shaped filter plate 421.
[0021] The bottom end of the stirring shaft 41 is fixedly connected to a second scraper 43. The rotation trajectory of the second scraper 43 is located on the bottom surface of the mixing tank 1. A motor 4 for driving the stirring shaft 41 is installed on the mixing tank 1 by means of a fixing component.
[0022] The mixing tank 1 has a feeding port 2 on its side wall and a support bracket 3 for support on its outer wall.
[0023] During operation, the current filtration of cement-based self-leveling mortar mainly occurs during the discharge process. However, when the discharge volume is too large, larger particles tend to accumulate on the filter screen, causing clogging and affecting the discharge effect. Furthermore, the large particles filtered out are inconvenient to recycle, which can easily lead to resource waste. In this solution, the stirring shaft 41 is driven by the motor 4. When the stirring shaft 41 rotates, it drives the connecting rod 422 to rotate. When the connecting rod 422 rotates, it drives the rolling wheel 423 to roll in the V-shaped groove of the V-shaped filter plate 421 and drives the first scraper 424 to scrape on the upper surface of the V-shaped filter plate 421. At the same time, the stirring shaft 41 rotates and drives the second scraper 43 to scrape on the bottom surface of the mixing tank 1. The stirring shaft 41 also drives the rotating grinding disc 46 to rotate on the lower surface of the fixed grinding disc 44. By feeding cement mortar raw materials into mixing bucket 1 through feeding port 2, the materials will fall down step by step from the filter holes of multiple V-shaped filter plates 421 after feeding. Larger particles will remain on the V-shaped filter plates 421, and the large particles will be concentrated in the V-shaped groove of the V-shaped filter plate 421 under the scraping of scraper 424. The large particles in the V-shaped groove will be crushed by the rolling of roller 423. After crushing, the particles that meet the filter hole diameter will leak down and be crushed by multiple roller crushing of multiple filter components 42. The crushed particles will be mixed with mortar raw materials for use, avoiding material waste. The raw materials leaking at the bottom of the mixing bucket 1 will gradually mix under the stirring of the second scraper 43, and in conjunction with the operation of the control conveying pump 6, the raw materials mixed in the mixing bucket 1 will be circulated and conveyed to the upper part of the mixing bucket 1. After the raw materials are discharged from the discharge end of the circulation pipe 5, they will enter the leakage port 45, and the rotating grinding disc 46 will grind and crush the raw materials again under the rotation, so as to further crush the large particles in the raw materials, so as to ensure the fluidity of the cement-based self-leveling mortar and improve the mixing effect of the mortar raw materials. After the raw materials are ground and mixed, the mixed raw materials in the mixing tank 1 can be discharged and used by opening the closed valve 8 and turning off the delivery pump 6; It achieves the function of mixing and filtering cement-based self-leveling mortar, which is more convenient to use than traditional mortar raw material mixing and filtering structures, effectively avoids material waste, and can improve the mixing effect of mortar raw materials.
