[0003] The existing cement paste mixer is not reasonable in the design of the stirring structure of most conventional devices in terms of stirring efficiency. The stirring blade often adopts a simple planar structure, and the layout lacks scientificity, and cannot form strong and orderly cement flow circulation during the stirring process. This leads to insufficient mixing of the cement in the stirring container, and local clumping or uneven composition is prone to occur, affecting the quality of the cement paste.

[0004] For equipment cleaning, most of the existing mixers lack effective automatic cleaning mechanisms. After stirring is completed, cement is easily attached to the stirring blade, the inner wall of the container and the like, and since there is no special cleaning device or the cleaning means is extremely simple, manual cleaning work is required.

The mixing plates 4 are inclined downwards to generate a downward thrust on the cement during mixing, causing the cement to form a mixture between the bottom and middle of the container. A stronger circulating flow and an inclination effectively prevent cement stagnation; one end of a mixing plate 4 near the inner wall of the assembly box 1 is fixed by a side scraper 11, the side scraper 11 is in contact with the inner wall of the assembly box 1, and a bottom scraper 12 is fixed at the bottom of the outer tube 3, the bottom scraper 12 is in contact with the bottom of the inner wall of the assembly box 1; a servo motor 5 is installed on the top of the assembly box 1, the output end of the servo motor 5 is connected to an output shaft 6, an output spur gear 7 is fixed on the outer side of the output shaft 6, and an actuating spur gear 8 that meshes with the output spur gear 7 is fixed on the outer side of the outer tube 3.

[0022] The rotatable connection between the outer tube 3 and the assembly box 1 ensures flexible rotation during mixing and cleaning. Multiple water spray holes 301 allow water to be evenly sprayed throughout the assembly box 1 during cleaning, achieving comprehensive cleaning. The downward-sloping mixing plate 4 exerts a downward thrust on the cement during mixing, creating a strong circulation flow between the bottom and middle of the container, enhancing the mixing effect, effectively preventing uneven mixing caused by cement stagnation, and improving the quality stability of the cement paste. The side scraper 11 contacts the inner wall of the assembly box 1, and the bottom scraper 12 contacts the bottom, promptly scraping off any adhering cement. The servo motor 5, through the transmission of the output shaft 6, output spur gear 7, and actuation spur gear 8, precisely controls the speed and direction of rotation of the outer tube 3. This can be flexibly adjusted according to different cement types and mixing requirements, improving the automation level and mixing accuracy of the equipment, and reducing the impact of human error on product quality.

[0023] like Figure 1 As shown, in this embodiment, during the stirring state, a sealing tube 10 is inserted into the outer tube 3. The sealing tube 10 can block the water spray hole 301 to prevent cement from entering the interior of the outer tube 3. The side wall of the assembly box 1 is fixed with a tube insertion component 13 for placing the sealing tube 10 when not in use.

[0024] The closed tube 10 effectively prevents cement from entering the outer tube 3 during mixing, ensuring the cleanliness of the internal structure of the outer tube 3. The insertion component 13 provides a dedicated storage place for the closed tube 10 when not in use, preventing loss or damage caused by careless placement, and facilitating quick access and storage by operators.

[0026] The plug-in end 901 of the water pipe joint 9 is inserted into the outer pipe 3, so that water can flow smoothly into the inside of the outer pipe 3, the rotating end 902 has an outer diameter greater than the outer pipe 3 and is rotationally connected with the outer pipe 3, so that the outer pipe 3 will not be hindered by the water pipe joint 9 when rotating to clean. The joint end 903 is connected with the water pipe 14, which is convenient for connecting with the external water supply system to realize stable supply of cleaning water. The plug-in pipe component 13 can store the water pipe joint 9 in the cleaning state, avoiding the messy placement of the water pipe joint 9 when not in use, and preventing it from being damaged or lost.

[0027] The working principle of the utility model is as follows:

[0028] The cement raw materials are poured into the assembly box 1 through the feeding hopper 2. Then the servo motor 5 is started, the output shaft 6 is driven to rotate by the output end of the servo motor 5, and the output spur gear 7 on the outer side of the output shaft 6 rotates accordingly. Since the outer side of the outer pipe 3 is fixed with the action spur gear 8 meshing with the output spur gear 7, the outer pipe 3 starts to rotate under the action of gear transmission. The outer surface of the section of the outer pipe 3 inside the assembly box 1 is fixed with a plurality of downward inclined stirring plates 4, and the stirring plates 4 stir the cement as the outer pipe 3 rotates. The downward inclined design of the stirring plates 4 generates a downward thrust on the cement during stirring, promoting the formation of strong circulating flow between the bottom and the middle of the container, effectively preventing the cement from stagnating, so that the cement can be fully mixed and evenly distributed.

[0029] During stirring, one end of the stirring plates 4 close to the inner wall of the assembly box 1 is fixed by the side scraper 11, the side scraper 11 is in contact with the inner wall of the assembly box 1, the bottom scraper 12 at the bottom of the outer pipe 3 is in contact with the bottom of the inner wall of the assembly box 1, and the side scraper 11 and the bottom scraper 12 can scrape off the cement adhering to the inner wall of the assembly box 1, further ensuring the uniformity of the cement slurry. At this time, the closed pipe 10 is plugged into the outer pipe 3, the closed pipe 10 blocks the water injection hole 301, preventing the cement from entering the inside of the outer pipe 3.

[0030] When the stirring operation is completed and the equipment needs to be cleaned, the closed pipe 10 is pulled out from the outer pipe 3 and placed on the pipe inserting part 13. Then the water pipe 14 is connected to the joint end 903 of the water pipe joint 9, at this time the plug-in end 901 of the water pipe joint 9 is inserted into the top of the outer pipe 3 and the rotating end 902 is rotationally connected with the outer pipe 3. Water enters the water pipe joint 9 through the water pipe 14 and then flows into the inside of the outer pipe 3. Since the outer surface of the outer pipe 3 is provided with a plurality of water spraying holes 301 in the section inside the assembly box 1, the water sprayed from the water spraying holes 301 can clean the inside of the assembly box 1, the stirring plate 4, the side scraping plate 11, the bottom scraping plate 12 and other components. During the cleaning process, the outer pipe 3 can be rotated under the drive of the servo motor 5, so that the water sprayed from the water spraying holes 301 can fully wash all parts inside the equipment, ensuring complete cleaning. The sewage after cleaning can be discharged through the discharge port at the bottom of the assembly box 1.
