Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a cement slurry mixer. Background Art

[0002] When a highway is being built, in order to ensure the quality and performance of road construction materials, samples of the cement used in the construction are taken. Then, a cement slurry mixer is used in the laboratory to mix cement and water in different proportions to achieve cement slurries of different proportions. The cement slurries of different proportions are then tested to select the proportion with the best performance for use in road construction.

[0003] The cement slurry mixer in the laboratory includes a mixer body, a support plate and a mixing pot. The current installation of the mixing pot has two methods: a matching through-hole is opened on the support plate, and the through-hole matches the plug-in column at the bottom of the mixing pot, and then the mixing pot is directly plugged into the support plate; another method is to open a groove on the support plate, and then a magnet is set in the groove to fix the mixing pot by magnetic attraction. Both installation methods are simple and convenient, but both have the following problems. First, during the mixing process, as the slurry becomes more and more viscous, the mixing pot rotates with the mixing blades, resulting in insufficient mixing, which causes deviations in the experimental results. Secondly, when taking the pot, because the plug-in column and the through-hole match, there is suction between the plug-in column and the through-hole, and the magnetic installation method and the plug-in column also have suction. The suction disappears at the moment the mixing pot is pulled out, and the inertia of its pulling out easily causes the slurry to spill out of the pot. In order to solve these problems, we propose a cement slurry mixer. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-5 The utility model provides a technical solution: a cement slurry mixer, comprising a cement slurry mixer body 1 and a mixing pot 2, a support plate 3 is arranged on the cement slurry mixer body 1, and a mounting through hole 4 is opened on the support plate 3, a receiving cavity 5 is opened on the inner wall of the mounting through hole 4, and a clamping mechanism 6 is arranged in the receiving cavity 5, a plug-in column 7 is welded on the bottom end of the mixing pot 2, and the mixing pot 2 is placed on the support plate 3 through the plug-in column 7 to penetrate the mounting through hole 4, the clamping mechanism 6 comprises a driving ring 601 and a clamping block 602 rotatably mounted inside the receiving cavity 5, the outer wall of the driving ring 601 and the inner wall of the receiving cavity 5 are rotationally matched, and a plurality of clamping blocks 602 are distributed in an annular array on the inner circle of the driving ring 601, a tooth groove 603 is opened in an annular array on the inner wall of the driving ring 601, and a tooth block 604 is arranged on the circumferential outer wall of the rotating end of the clamping block 602, and the tooth block 604 and the tooth groove 603 are meshed and matched.

[0025] In this embodiment, the cement slurry mixer body 1 is the prior art and will not be elaborated here. A driving mechanism is provided in the cement slurry mixer body 1 to drive the support plate 3 to move up and down. When the support plate 3 is at the bottom, it is the installation or disassembly position of the mixing pot 2. After the support plate 3 moves up, it will drive the mixing pot 2 and the stirring blades in the cement slurry mixer body 1 to match, so that the stirring blades can fully stir the cement slurry inside the mixing pot 2.

[0026] Specifically, the installation hole 4 is opened at one end of the support plate 3 away from the cement slurry mixer body 1, and the diameter of the installation hole 4 is larger than the outer diameter of the plug-in column 7, so that there will be no matching suction after the plug-in column 7 of the mixing pot 2 is inserted into the installation hole 4, thereby avoiding the situation where the mixed cement slurry is splashed due to inertia when taking the pot.

[0027] Furthermore, the clamping mechanism 6 is arranged in the accommodating cavity 5, and the multiple clamping blocks 602 of the annular array are all installed in the accommodating groove 5 by rotating the rotating shaft. In the initial state, the clamping mechanism 6 is completely located in the accommodating cavity 5. When the driving ring 601 rotates, the tooth groove 603 on the driving ring 601 engages with the tooth block 604 on the multiple clamping blocks 602 of the annular array, so that the multiple clamping blocks 602 of the annular array are all rotated around the rotating shaft, so that the other end of the clamping block 602 protrudes from the accommodating groove 5 by rotation and enters the installation hole 4, and then squeezes the outer wall of the plug-in column 7, so that the stirring pot 2 is fixed.

[0028] A matching surface 605 is formed at one end of the clamping block 602 away from the rotating end, and the matching surface 605 matches the side wall of the plug-in column 7 .

[0029] In this embodiment, the matching surface 605 matches the side wall of the plug-in column 7. When the clamping block 602 presses the outer wall of the plug-in column 7, the contact area is increased through the matching surface 605, so that the clamping and fixing of the stirring pot 2 is more secure.

[0030] A movable groove 8 is provided on the inner wall of the accommodating chamber 5, and the movable groove 8 penetrates the accommodating chamber 5 and is connected with the outside. A driving rod 9 is movably installed in the movable groove 8, and one end of the driving rod 9 is welded to the outer wall of the driving ring 601. Spring grooves 10 are provided on the upper and lower ends of the circumferential outer wall of the driving ring 601, and a return spring 11 is fixedly installed in the spring groove 10. Stoppers 12 are welded on the upper and lower ends of the circumferential inner wall of the accommodating chamber 5, and the stopper 12 and the other end of the return spring 11 are fixedly connected, and the stopper 12 and the spring groove 10 are slidably matched.

[0031] A protective cover 13 is rotatably mounted on one side of the mixing area of ​​the cement slurry mixer body 1, and a push plate 14 is provided on the protective cover 13, and the push plate 14 matches the driving rod 9, and a lock buckle 15 is provided at one end of the protective cover 13 away from the rotating shaft.

[0032] In this embodiment, the protective cover 13 is U-shaped and forms a closed space with the cement slurry mixer body 1 by rotating, thereby achieving the purpose of preventing cement slurry from splashing during mixing. The push plate 14 is a long strip and is longitudinally arranged at the U-shaped bottom end of the protective cover 13. The push plate 14 and the U-shaped bottom end of the protective cover 13 are inclined, so that when the push plate 14 pushes the driving rod 9, the thrust direction and the contact edge direction of the push plate 14 are similar, so that the push plate 14 has better strength.

[0033] A rotation groove 16 is formed on one side of the driving rod 9 , and a roller 17 is rotatably mounted in the rotation groove 16 .

[0034] In this embodiment, after the protective cover 13 is closed, the push plate 14 is tightly against the driving rod 9, and the push plate 14 has an extrusion force on the driving rod 9. At this time, if the cement slurry mixer body 1 drives the support plate 3 to move up, the upward movement of the support plate 3 is more difficult and a harsh friction sound will be emitted. Through the setting of the roller 17, after the protective cover 13 is closed, the push plate 14 is in contact with the roller 17, so the support plate 3 can move up smoothly.

[0035] Working principle: When mixing cement slurry, take a certain proportion of cement and water and add them into the mixing pot 2, then insert the plug-in column 7 at the bottom of the mixing pot 2 into the mounting hole 4 of the support plate 3, rotate and close the U-shaped protective cover 13, and then lock it through the lock buckle 15. The push plate 14 on the protective cover 13 pushes the driving rod 9 when rotating, so that the driving ring 601 connected to the driving rod 9 rotates about its own axis in the accommodating chamber 5. The rotation of the driving ring 601 will squeeze the reset spring 11. At the same time, when the driving ring 601 rotates, the tooth groove 603 on its inner wall and the tooth block 604 on the clamping block 602 engage, so that the multiple clamping blocks 602 in the annular array rotate, and the mixing pot 2 is clamped and fixed on the support plate 3 through the fitting of the matching surface 605 and the outer wall of the plug-in column 7, and then the support plate 3 is moved upward by the driving mechanism in the cement slurry mixer body 1 until the stirring blade and the mixing pot 2 can match, and the stirring blade can be started to stir the cement slurry.

[0036] After the stirring is completed, the lock buckle 15 is unlocked, and the resilience of the reset spring 11 pushes the drive ring 601 to rotate, driving the drive rod 9 to rotate, thereby pushing the push plate 14 to open the protective cover 13. At the same time, the reset of the drive ring 601 drives the clamping block 602 to rotate and shrink into the accommodating chamber 5, unlocking the clamping of the stirring pot 2. At this time, the stirring pot 2 can be directly moved up and taken out.
