Description

Technical Field

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

[0002] Cement slurry mixer can stir the cement and water mixture specified in the standard into a uniform trial slurry for measuring the standard consistency and setting time of cement and making safety test blocks. It is one of the necessary equipment for cement plants, construction units, relevant professional colleges and universities, and cement laboratories of scientific research institutions.

[0003] A cement slurry mixer is usually composed of a base, an arm, a support frame, a stirring device, and a pot body. The support frame is arranged on the arm and can move up and down along the arm. When in use, the support frame is placed at the lowest point, and then the pot body is placed on the support frame, and then the support frame is lifted to a position suitable for stirring. The process of removing the pot body is reversed. The Chinese patent with application number CN202021001278.8 provides a cement slurry mixer that is easy to lift and lower, including a base, an arm, a support frame, a stirring device and a pot body. The stirring device is arranged above the base through the arm, the support frame is arranged on the arm and can move up and down along the arm, and a crank is arranged on the arm to control the up and down movement of the support frame. The arm is provided with a circular through hole, and a connecting block is provided at the bottom of the pot body. An electromagnet is provided at the lower part of the circular through hole. The electromagnet is connected to the electromagnet module located in the arm through a wire. The electromagnetic control module includes a switch connected to the crank, and the switch includes a conductive slip ring and a slip ring brush, and the conductive slip ring is provided with an opening. Although the above structure can improve the stability of the pot body and facilitate the rapid lifting and lowering operation of the support frame and the pot body, there are the following problems when using it: 1. The pot body is heavy and the pot body needs to be lifted and lowered for each stirring work, which will cause the overall energy consumption of the device to be high; 2. There is no cleaning device for the stirring device, resulting in a layer of dried cement slurry often attached to the stirring device. After long-term use, the weight of the stirring device will increase and thus increase energy consumption. Moreover, if the dried cement slurry is mixed into the new slurry in block form, it will affect the stirring effect. Utility Model Content

[0004] The utility model aims to provide a cement slurry mixer which is easy to lift. The overall energy consumption of the equipment is reduced by driving the stirring rod to lift instead of driving the pot body to lift in traditional equipment.

[0019] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0020] Example

[0021] like Figure 1-2 As shown, a cement slurry mixer that is easy to lift includes a base 1, an arm 2, a stirring device 3, a pot body 4 and a cleaning device, and the arm 2 is located at one end of the base 1. Threaded holes are provided at the four corners of the base 1, and threaded rods 6 adapted thereto are provided in the threaded holes. A knob 7 is provided at the top of the threaded rod 6, and a support foot 8 is provided at the bottom of the threaded rod 6. Rotating the knob 7 can adjust the height of the corners of the base 1, thereby realizing the leveling of the base 1, and can also enable the base 1 to adapt to uneven ground to stably support the overall structure.

[0022] The stirring device 3 includes a lifting power device 31, a lifting rod of the lifting power device 31 passes through the top plate of the support arm 2 and is connected to the mounting seat 32 of the rotating power device 33. The lifting power device 31 can be a cylinder, and the rotating power device 33 can be a motor. The lifting power device 31 can drive the rotating power device 33 to lift. The rotating power device 33 is connected to the stirring rod 35 through a transmission box 34. The transmission box 34 is provided with a meshing worm gear and a worm. The worm gear is fixedly connected to the output shaft of the rotating power device 33, and the worm is fixedly connected to the stirring rod 35. The bottom end of the stirring rod 35 is provided with a stirring blade. The rotating power device 33 can drive the stirring rod 35 to rotate to achieve the stirring of the cement slurry.

[0023] The cleaning device includes a high-pressure nozzle 5 corresponding to the stirring rod 35, and the high-pressure nozzle 5 is connected to a water tank, and the high-pressure nozzle 5 can clean the stirring rod 35. The water tank is located in the support arm 2 and below the lifting power device 31. A high-pressure pump is provided in the water tank, and the high-pressure pump is connected to the high-pressure nozzle 5 through a water pipe. The support arm 2 is provided with a water inlet communicated with the water tank.

[0024] The pot body 4 is located directly below the stirring rod 35, and the pot body 4 is connected to the base 1 through a stopper 9, and a groove 10 is provided on the stopper 9 to match the structure of the pot body 4, and the groove 10 can increase the stability of the pot body 4. The stopper 9 is also provided with a discharge channel 11 connected to the groove 10, and the top port of the discharge channel 11 is arranged opposite to the bottom discharge port of the pot body 4, and the bottom port of the discharge channel 11 is connected to the discharge pipe 12, and a valve is provided on the discharge pipe 12. The size of the top port of the discharge channel 11 can be larger than the size of the discharge port, so that the slurry in the pot body 4 can be smoothly removed.

[0025] When in use, the lifting power device 31 is used to drive the rotating power device 33 and the stirring rod 35 to descend, so that the stirring rod 35 enters the pot body 4 for stirring. After the stirring is completed, the lifting power device 31 is used to drive the rotating power device 33 and the stirring rod 35 to rise and move out of the pot body 4 to stop stirring, and the discharge pipe 12 is used to remove the stirred material in the pot body 4. After the material is removed, the high-pressure pump is turned on, and the stirring rod 35 is cleaned by the high-pressure nozzle 5 to prevent the material from drying on the stirring rod 35 and causing the weight of the stirring rod 35 to increase, and further prevent the increase in energy consumption and the reduction in stirring effect when the stirring rod 35 rotates. During cleaning, the rotating power device 33 drives the stirring rod 35 to rotate for all-round cleaning. When cleaning the stirring rod 35, part of the cleaning water will flow into the pot body 4 for cleaning the pot body 4, thereby realizing the reuse of part of the water resources, and at the same time preventing the material from drying on the inner wall of the pot body 4 and the discharge channel 11, so as to facilitate the subsequent thorough cleaning of the pot body 4 and the discharge channel 11.

[0026] Therefore, the utility model adopts the cement slurry mixer with the above structure that is easy to lift, and can use the lifting of the stirring rod instead of the lifting of the pot body to reduce energy consumption. It can also use a cleaning device to keep the stirring rod clean to further reduce energy consumption and ensure the stirring effect.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
