[0002] Ready-mix concrete pumping technology is widely used in construction, especially in high-rise and super-high-rise building construction, where its convenience and efficiency are particularly important. To ensure smooth pumping, the pump pipe must be wetted and lubricated before pumping concrete to reduce friction between the concrete and the pump pipe, thereby avoiding potential problems during the pumping process.

[0003] At present, in order to solve the problem of wetting and lubricating the pump pipe before concrete is pumped, the existing technical means are usually to use tank trucks to transport the pump-lubricating mortar to the construction site and use the pump-lubricating mortar to wet and lubricate the pump pipe. During the transportation process, in order to prevent the pump-lubricating mortar from stratifying or adhering to the inner wall of the storage tank, the pump-lubricating mortar usually needs to be stirred.

[0004] However, existing mixing tanks for transporting lubricating pump mortar usually use a mixing rod to rotate at a constant speed to stir the lubricating pump mortar, which not only has high energy consumption but also cannot accurately control the mixing uniformity and stability of the lubricating pump mortar.

DETAILED DESCRIPTION

[0025] The following will be combined with the Figure 1 -Attached Figure 3 The technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention and do not constitute a complete set of implementations. Those skilled in the art can combine the embodiments of the present invention to derive other embodiments without inventive work, and such embodiments are also within the scope of protection of the present invention.

[0026] The inventors of this application have discovered that existing mixing tanks for transporting lubricating pump mortar typically use a stirring rod that rotates at a constant speed to stir the lubricating pump mortar, which not only consumes a lot of energy but also makes it difficult to accurately control the mixing uniformity and stability of the lubricating pump mortar. Therefore, this application discloses a mixing tank for transporting lubricating pump mortar with intelligent stirring, which mainly adopts the following solutions:

[0027] The embodiment of the present application discloses a mixing tank with intelligent mixing function and a pump-type mortar transporting device. Figure 1, including a tank body 1 and a stirring rod 2 rotatably arranged in the tank body 1, a feed port 11 is opened on the top wall of the tank body 1, a discharge pipe 12 is connected to the position near the bottom of the tank body 1, a valve 121 is provided on the storage tank, a shaft sleeve 21 is provided on the stirring rod 2, a plurality of stirring blades 22 are fixedly provided on the shaft sleeve 21, and the stirring blades 22 are distributed at equal intervals along the circumference of the shaft sleeve 21, and a power unit for driving the stirring rod 2 to rotate is provided on the tank body 1.

[0028] Reference Figure 1 The power unit includes a servo motor 13 and a gearbox 14. Both the servo motor 13 and the gearbox 14 are fixedly mounted on the tank body 1. The output shaft of the servo motor 13 is coaxially fixedly connected to the input shaft of the gearbox 14. The output shaft of the gearbox 14 is coaxially fixedly connected to the stirring rod 2. The servo motor 13 can use a permanent magnet synchronous motor or an AC asynchronous motor as its power source, while the gearbox 14 can use a planetary reducer or a parallel shaft reducer to meet the speed adjustment requirements under different working conditions. The tank body 1 is also equipped with an electronic control system 15. The electronic control system 15 is electrically connected to the servo motor 13 and the gearbox 14 respectively. The electronic control system 15 controls the start-up of the servo motor 13 and adjusts the rotation speed of the stirring rod 2 by controlling the gearbox 14.

[0029] Reference Figure 2 、 3 A guide block 211 is fixedly provided on the inner side wall of the sleeve 21, and a guide groove 23 is opened on the side wall of the stirring rod 2 along the circumference of the stirring rod 2. The guide groove 23 is arc-shaped, and the guide block 211 is arranged in the guide groove 23; the stirring rod 2 is provided with a resistance sensing unit for detecting the resistance of the stirring blade 22 to the mortar. The resistance sensing unit includes a pressure sensor 24. The pressure sensor is fixedly provided in the guide groove 23 and abuts against the guide block 211. The pressure sensor 24 is electrically connected to the electronic control system 15.

[0030] During operation, the pressure variation range of the pressure sensor 24 is preset first. The rotation of the stirring rod 2 drives the stirring blade 22 to rotate. The stirring blade 22 stirs the lubricating mortar. The stirring blade 22 is subjected to resistance from the lubricating mortar and transmits it to the pressure sensor 24. The pressure sensor 24 detects in real time the size of the resistance of the lubricating mortar suffered by the stirring blade 22 during the stirring process. When the size of the resistance of the lubricating mortar suffered by the stirring blade 22 exceeds or decreases to a certain range, the electronic control system 15 automatically controls the gearbox 14 to adjust the rotation speed of the stirring rod 2 to increase or decrease the rotation rate of the stirring rod 2.

[0031] Reference Figure 2 、 3, a flexible sleeve 25 is sleeved on the stirring rod 2 and on the upper and lower sides of the sleeve 21. The two ends of the flexible sleeve 25 are fixedly connected to the stirring rod 2 and the sleeve 21 respectively. The flexible sleeve 25 is made of elastic materials such as rubber and silicone. Through the setting of the flexible sleeve 25, the lubricating pump mortar can be prevented from entering the gap between the sleeve 21 and the stirring rod 2, thereby preventing the lubricating pump mortar from solidifying in the gap between the sleeve 21 and the stirring rod 2, causing the sleeve 21 to be stuck on the stirring rod 2, affecting the detection accuracy of the resistance sensing unit.

[0032] Reference Figure 3 The design forms of the stirring blade 22 are various, and paddle-type, spiral-type or other forms of blades can be selected according to actual conditions. For example, the paddle-type stirring blade 22 is suitable for low-viscosity lubricating pump mortar, while the spiral-type stirring blade 22 is more suitable for the stirring requirements of high-viscosity lubricating pump mortar. In order to facilitate the installation of different types of stirring blades 22 according to the stirring requirements, the stirring blade 22 and the shaft sleeve 21 are set to a detachable connection form. Specifically, a mounting block 221 is fixedly provided on the stirring blade 22, and a mounting groove 212 for inserting the mounting block 221 is provided on the side wall of the shaft sleeve 21. The mounting groove 212 is opened along the length direction of the shaft sleeve 21. The mounting block 221 can adopt a dovetail block, a T-shaped block or other blocks of special shapes, and the mounting groove 212 is adapted to the mounting block 221.

[0033] Reference Figure 3 The shaft sleeve 21 is also provided with a fixing assembly for preventing the mounting block 221 from detaching from the mounting groove 212. The fixing assembly includes a fixing ring 213 and a fixing member 214. The fixing ring 213 is made of a high-strength alloy material to ensure its firmness and reliability. The fixing member 214 is usually a bolt. After each stirring blade 22 is installed on the shaft sleeve 21, the fixing ring 213 is sleeved on the shaft sleeve 21 and fixed by bolts. This prevents the mounting block 221 on each stirring blade 22 from detaching from the mounting groove 212 on the shaft sleeve 21, thereby achieving the purpose of fixing the stirring blade 22.

[0034] The implementation principle of the intelligent stirring lubricant pump mortar transport mixing tank in the embodiment of the present application is: when working, the pressure variation range of the pressure sensor 24 is preset first, and the stirring rod 2 rotates to drive the stirring blade 22 to rotate, and the lubricant pump mortar is stirred by the stirring blade 22. The stirring blade 22 is subjected to resistance from the lubricant pump mortar and is transmitted to the pressure sensor 24. The pressure sensor 24 detects in real time the size of the resistance of the lubricant pump mortar suffered by the stirring blade 22 during the stirring process. When the size of the resistance of the lubricant pump mortar suffered by the stirring blade 22 exceeds or decreases to a certain range, the electronic control system 15 automatically controls the gearbox 14 to adjust the rotation speed of the stirring rod 2 to increase or decrease the rotation rate of the stirring rod 2, thereby being able to accurately control the mixing uniformity and stability of the lubricant pump mortar, while effectively reducing energy consumption.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
