Description

Technical Field

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

[0002] Cement is an indispensable raw material in the construction industry. The quality of cement also plays a key role in the quality of construction. The consistency of cement paste is an important indicator to measure the quality of cement. The standard consistency of cement paste indicates the thinness of cement paste, which is the ratio of water consumption to cement mass when the cement paste reaches the standard consistency. The purpose of determining the standard consistency is to measure the cement paste under the condition of standard consistency during the cement setting time and stability test, so that different cements can be comparable. The standard consistency of cement paste can be used to know the water requirement of various brands of cement. The quality of cement with large water requirement is worse than that of cement with small water requirement. It is an important indicator for evaluating cement quality. The standard consistency of cement paste is the consistency of cement paste when the test rod is sunk into the paste and is 6±1mm away from the bottom plate measured by Vicat instrument.

[0003] The process of preparing cement paste of standard consistency: first add an appropriate amount of water into the mixing pot (the amount of cement of standard consistency is 500g). Then put the mixing pot on the pot base of the cement paste mixer, stir the mixing blade at low speed for 120s, stop for 15s, and then stir at high speed for 120s. After stopping, take out the cement paste in the mixing pot, squeeze it into the test mold, compact it and scrape it flat. From its preparation process, it can be seen that the mixing pot and other parts will be in direct contact with the cement paste and be stuck with cement paste. If it is not cleaned, it will affect the second sample making or the guide equipment cannot be used. Therefore, cement paste cleaning is an indispensable process.

[0004] In the prior art with publication (announcement) number: CN218429147U and publication (announcement) date: 2023-02-03, a cement slurry mixing device for large-volume concrete is disclosed, and a cleaning mechanism is provided on one side of the base column, the cleaning mechanism includes a fixed frame and a transmission motor, one side of the base column is fixedly connected to the fixed frame, the inner side of the fixed frame is fixedly connected to a fixed plate, the top of the fixed plate is fixedly connected to the transmission motor, the bottom of the transmission motor is fixedly connected to a power rod, and the surface of the power rod is fixedly connected to a cleaning brush, and a liquid storage mechanism is provided on the other side of the base column, and the liquid storage mechanism includes a liquid storage tank and a liquid inlet.

[0005] In the above-mentioned prior art, after the power rod is rotated, the cleaning brush can be driven to rotate. At this time, the cleaning brush can be used to clean along the inside of the mixing pot. The mixing pot can be cleaned in a portable manner to remove residual concrete, thereby reducing the workload of the operator. However, the above-mentioned cleaning operation requires the worker to hold the mixing pot and the cleaning brush close to each other and rotate them, and the cleaning operation is not convenient enough. Therefore, a cleaning device for cement slurry is proposed to optimize the above-mentioned structure. Utility Model Content
