Description

Technical Field

[0001] This utility model belongs to the field of mixer technology, and in particular to a cement paste mixer for cement testing. Background Technology

[0002] Cement paste mixers mix cement and water according to standard specifications to form a uniform test paste for determining cement standard consistency, setting time, and preparing safety test blocks. It is a commonly used piece of equipment in concrete testing. During mixing, cement and water are added to the same mixing drum. Existing mixers, by installing adjustment components, allow the mixing drum to tilt, facilitating material discharge and cleaning (cleaning prevents cement from adhering to the inner wall of the drum, corroding it, and significantly shortening its lifespan), increasing the device's practicality. However, while this increases practicality to some extent, manual cleaning is still required, making the cleaning of the mixing drum time-consuming and labor-intensive.

[0003] A search of Chinese patent documents (authorization announcement number CN218227216U) reveals that this application relates to the technical field of concrete testing equipment, and particularly to a cement paste mixer, which includes a base frame, a mixing pot, a splash guard, a water tank, a mixing mechanism, a tilting mechanism, and a lifting mechanism. The tilting mechanism includes a U-shaped frame, a rotating shaft, and a fixing component for fixing the mixing pot. The rotating shaft is horizontally positioned, connected to the U-shaped frame, passes through a pot support, and the mixing pot can rotate around the rotating shaft. This cement paste mixer uses a lifting mechanism to drive the U-shaped frame to rise and fall vertically, thereby adjusting the height of the mixing pot, and uses a fixing component. While this patent increases the practicality of the device to some extent, it requires manual cleaning during the washing process, making the cleaning of the mixing drum time-consuming and labor-intensive.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This cement slurry mixer for cement testing, thanks to the design of the scraper, adjustment components, and auxiliary components, achieves cement mixing by starting the first stepper motor to drive the mixing paddle. The servo motor then drives the gears, which in turn rotate the mounting plate at the top of the drive shaft, causing the mixing paddle and scraper to switch positions. Activating the second stepper motor then drives the scraper to rotate, achieving automatic cleaning. This makes cleaning time-saving and labor-saving. The adjustment components allow for position adjustment of the mixing drum and assist in mixing and cleaning, greatly increasing the automation level of the device and making it more labor-saving. The auxiliary components also facilitate the fixing and rotation of the mixing drum, enabling rapid material discharge.

A mounting box 2 is fixedly connected to the side of the workbench 1. The mounting box 2 is L-shaped, and a drive shaft 3 is connected through its inner side. A servo motor 14 is mounted at the bottom of the mounting box 2. Gears 15 are connected to both the drive end of the servo motor 14 and the outer periphery of the drive shaft 3. Both gears 15 are installed inside the mounting box 2, and their dimensions are determined according to actual conditions. The two gears 15 mesh with each other. A rectangular mounting plate 4 is fixedly connected to the top of the drive shaft 3. The top of the mounting plate 4 is fitted with the fixed end of the first stepper motor 7.

During cleaning, the rotation of the scraper 12 can clean the mud in the mixing tank 9. During cleaning, a certain amount of cleaning water is added to the mixing tank 9.

[0027] A filter screen 13 is embedded in the top of the workbench 1. The filter screen 13 is designed to filter the cleaning water so that it can be reused. Two drain pipes are connected to the side of the workbench 1. The adjustment component 5 includes two limiting plates 52 installed on the side of the workbench 1, a lead screw 53 installed between the two limiting plates 52, and a drive motor 51 installed on the side of the limiting plates 52 to provide adjustment power for the lead screw 53.

The outer circumference of the lead screw 53 is threaded with a linkage block 54, and one end of the linkage block 54 passes through the limiting groove on the side of the workbench 1 and is connected to a holding platform 56. The bottom end of the holding platform 56 is equipped with the fixed end of an electric push rod 55, and the driving end of the electric push rod 55 passes through the holding platform 56 and is connected to a placement plate 57. The placement plate 57 is embedded in the holding platform 56 and can move up and down.

The power supply is also common knowledge in the art. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. The scale of the attached drawings is for reference only and can be adjusted to a certain extent according to the actual use.

[0030] Working principle

[0031] This cement paste mixer for cement testing is used by adding cement and water into the mixing drum 9. The drive motor 51 is started to adjust the placement plate 57 on the side of the lead screw 53, so that the mixing drum 9 is directly below the mixing paddle 8. The electric push rod 55 is then started to raise the placement plate 57, causing the mixing paddle 8 to embed into the mixing drum 9. The first step motor 7 is then started to rotate the mixing paddle 8 for mixing. After processing is complete, the electric push rod 55 is started to reset the placement plate 57. The drive motor 51 is then started to move the mixing drum 9 between the two fixed plates 64. The operation is then adjusted according to the actual situation. The electric push rod 55 raises the mixing tank 9 to a certain height. The hydraulic rod 62 is activated to adjust the support column 70 at the bottom of the linkage plate 63. The adjustment of the support column 70 causes the slider 67 at the bottom of the movable rod 69 to move in opposite directions, thereby clamping the mixing tank 9 with the fixed plate 64. The forward and reverse motors 65 are activated to rotate the fixed mixing tank 9 as needed. When cleaning is required, the servo motor 14 is activated to rotate the mounting plate 4 at the top of the drive shaft 3, so that the mixing paddle 8 and the scraper 12 are swapped. The above operation is repeated to carry out the cleaning operation.
