Description

Technical Field

[0001] This utility model relates to the technical field of cement building material experimental equipment, specifically a cement paste mixing device. Background Technology

[0002] Cement paste mixing equipment is a key piece of equipment in cement performance testing. It is used to mix cement and water in a standard ratio to prepare a homogeneous cement paste. In a laboratory environment, cement paste mixing equipment is used frequently, and the mixing blades and container must be thoroughly cleaned after each use to prevent residual cement from affecting the accuracy of subsequent test results.

[0003] Existing cement paste mixing equipment typically includes a mixer body, mixing blades, and a base. After use, operators need to manually wipe or rinse the mixing blades with water, a process that presents several problems: First, the mixing blades are in a fixed position, requiring operators to bend over or use auxiliary tools during cleaning, making it inconvenient and inefficient; second, cement slurry easily drips onto the base during cleaning, not only contaminating the equipment but also making it difficult to remove the dried cement; third, traditional cleaning methods often result in water waste and environmental pollution.

[0004] Therefore, there is an urgent need in this field for a cement paste mixing device that is simple in structure, easy to operate, and has a good cleaning effect. Utility Model Content

[0005] The purpose of this invention is to provide a cement slurry mixing device that solves the problems of inconvenient cleaning of mixing blades, cement slurry contamination of the base during cleaning, and low cleaning efficiency in the prior art.

[0006] To achieve the above objectives, this utility model provides a cement paste mixing device, including a mixer body. The mixer body includes a base and mixing blades mounted on the base. A column fixedly connected to the base is provided on one side of the mixing blades. The lower end of the column is rotatably connected to the base via a bearing in a bearing seat, and the bearing seat is fixedly connected to the base. A positioning sleeve is fitted on the side wall of the column, and the positioning sleeve is fixedly positioned to the column by a locking mechanism. A swing rod is horizontally mounted on the positioning sleeve. One end of the swing rod is fixedly connected to the side wall of the positioning sleeve, and the other end is a horizontally suspended free end. A cleaning bucket is provided at the suspended end of the swing rod, and a lifting mechanism is movably fitted on the inner side wall of the cleaning bucket. The lifting ring is a circular cylindrical body that fits inside the cleaning tank. The cleaning tank and the lifting ring are secured together by screws in threaded holes on the upper side wall of the cleaning tank. To adjust the height, simply loosen the screws to raise or lower the lifting ring. The lifting ring's fit inside the cleaning tank prevents cleaning fluid from leaking out through the gap between them. The upper end of the lifting ring is fitted with a cap, which has a rectangular inlet for the agitator blades to pass through. A spray structure is located below the cap. By pulling the lifting ring upwards, the agitator blades are vertically inserted into the cleaning tank through the inlet, and the spray structure facilitates cleaning of the inserted blades.

[0007] Because the mixing blades are fixed, the operator can only move the cleaning bucket directly under the mixing blades by manually rotating the positioning sleeve on the column, which in turn rotates the swing arm. After use, removing the mixing bucket causes cement slurry to drip onto the base, and the mixing blades are also difficult to clean, affecting subsequent tests. Therefore, by moving the cleaning bucket horizontally under the mixing blades, the dripping cement slurry is collected, preventing soiling the base. Simultaneously, inserting the mixing blades into the cleaning bucket prevents water from overflowing during cleaning.

[0008] Preferably, the swing rod is a telescopic rod, comprising a fixed tube and a telescopic tube disposed at its telescopic end. The fixed tube is a rectangular hollow tube, and the telescopic tube is a rectangular hollow tube. The telescopic tube portion is fitted inside the hollow cavity of the fixed tube. Screw holes are provided on the side wall of the fixed tube, and the two are fastened together by screws installed in the screw holes. Because the stirring blade rotates eccentrically, with the rotation position far from the central axis, the telescopic nature of the swing rod and the rotating structure positioned on the column allow the cleaning bucket to move at multiple angles to directly below the stirring blade.

[0009] Preferably, the bottom of the cleaning bucket is provided with a drain outlet, which is connected to a drain pipe, and a valve is provided on the drain pipe. The wastewater after cleaning can be easily discharged through the drain pipe and valve.

[0010] Preferably, the spray structure includes multiple annular spray pipes disposed on the inner sidewall of the lifting ring, each spray pipe being equipped with multiple nozzles, and the spray pipes being connected by connecting pipes, which are connected to a water supply pipe via pipe fittings. The nozzles are evenly distributed on the spray pipes to ensure thorough cleaning of the stirring blades.

[0011] Preferably, each of the spray pipes is connected to a water supply pipe via a pipe fitting. The water supply pipe can be connected to an external water source to provide water for cleaning.

[0012] Preferably, an operating lever is fixedly installed on the side wall of the column. The operating lever allows for manual rotation of the column to adjust the position of the cleaning bucket.

[0013] Preferably, a filter screen is installed on the side wall near the bottom of the cleaning tank to intercept and separate cement. The filter screen can filter cement particles in the cleaning solution, facilitating cement recycling and water reuse.

[0014] More preferably, the locking mechanism includes a locking screw disposed on the side wall of the positioning sleeve. The locking screw passes through the side wall of the positioning sleeve and contacts the outer surface of the column. The positioning sleeve and the column are fixed by tightening the locking screw.

[0015] The beneficial effects of this utility model are: 1. This utility model features a movable cleaning bucket and spray structure, allowing the stirring blades to be directly inserted into the cleaning bucket for automatic cleaning without the need for manual wiping, resulting in thorough and efficient cleaning.

[0016] 2. This utility model collects dripping cement slurry by moving the cleaning bucket directly under the mixing blades, thus preventing contamination of the base and the surrounding environment of the equipment.

[0017] 3. This utility model allows the cleaning bucket to be flexibly adjusted in position by means of the telescopic structure of the swing rod and the rotating structure of the positioning sleeve, so as to adapt to the stirring blades of different sizes and positions.

A screw is installed in each threaded hole, and the cleaning tank 4 is fastened to the side wall of the lifting ring 5 by tightening the screws. When it is necessary to adjust the height of the lifting ring 5, the screws are loosened to raise or lower the lifting ring 5. The lifting ring 5 fits inside the cleaning tank 4 with a very small gap between them to prevent the cleaning liquid from overflowing from the gap. To further prevent leakage, an annular groove is provided on the outer side wall of the lifting ring 5, and an elastic sealing ring is fitted inside the groove. The sealing ring is in close contact with the inner wall of the cleaning tank 4.

[0026] In this embodiment, please refer to Figure 1 , 2 3. A cover 6 is provided at the upper end of the lifting ring 5. The cover 6 is preferably a transparent glass plate to facilitate observation of the cleaning status of the stirring blades 12 inside the cleaning tank 4. The cover 6 is fixedly connected to the lifting ring 5 by bolts. The cover 6 is provided with a placement port 61 for the stirring blades 12 to pass through. The placement port 61 is a rectangular strip, and its size is slightly larger than the cross-sectional size of the stirring blades 12 to facilitate the insertion of the stirring blades 12.

[0027] In this embodiment, please refer to Figure 1 , 4A spray structure 7 is provided below the cap 6. The spray structure 7 includes multiple annular spray pipes 71 mounted on the inner wall of the lifting ring 5. Each spray pipe 71 has multiple nozzles 72. The spray pipes 71 are connected by connecting pipes 73, which are connected to a water supply pipe 75 via pipe connectors 74. The spray pipes 71 are evenly distributed directly below the placement opening 61, and multiple nozzles 72 are spaced apart along the length of each spray pipe 71. The nozzles 72 are evenly distributed, horizontally or inclined downwards, aimed at the stirring blades 12 inserted into the placement opening 61, ensuring comprehensive cleaning of the stirring blades 12 with cleaning fluid. The water supply pipe 73 can be connected to an external water source, such as a water tank or reservoir. A booster pump draws the cleaning fluid from the water tank or reservoir and supplies it to the water supply pipe 73. A solenoid valve is installed on the water supply pipe 73, connected to a controller to control the cleaning process.

[0028] In this embodiment, please refer to Figure 1 , 3 4. A drain outlet is located at the bottom of the cleaning bucket 4, connected to a drain pipe 91. A valve 92, a manual ball valve, is installed on the drain pipe 91. The bottom of the cleaning bucket 4 is sloped, with the drain outlet at the lowest point to facilitate complete drainage of wastewater.

[0030] The working process of this utility model is as follows: After the cement slurry mixing device is used and the mixing tank is removed, when it is necessary to clean the mixing blades 12, the operator first loosens the locking screws on the positioning sleeve 22, adjusts the height and rotation angle of the positioning sleeve 22, and simultaneously adjusts the extension length of the swing rod 3 so that the cleaning tank 4 is moved directly below the mixing blades 12. Then, the lifting ring 5 is pulled upwards so that the mixing blades 12 are inserted into the cleaning tank 4 through the placement port 61. The height of the lifting ring 5 is adjusted so that the mixing blades 12 are completely immersed in the cleaning tank 4 or within the spray range, and then the screws on the lifting ring 5 are tightened to fix the height. The solenoid valve on the water supply pipe 73 is opened, and cleaning water is sprayed out through the spray pipe 71 and the nozzle 72 to spray and clean the mixing blades 12. During the cleaning process, the cement slurry remaining on the mixing blades 12 is washed off and falls to the bottom of the cleaning tank 4. The filter screen 10 intercepts cement particles, and the water can be discharged and recycled through the filter screen 10. After cleaning, the water supply valve is closed, and the valve 92 on the drain pipe 91 is opened to discharge the sewage. If cement particles need to be recycled, the cement residue on the filter screen 10 can be cleaned. The entire cleaning process is simple and quick, without moving the mixing blades 12, avoiding cement slurry dripping and contaminating the base, while also ensuring thorough cleaning and preparing for the next test.
