Detailed Embodiments

[0020] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present disclosure.

[0021] The embodiments of the present disclosure will be described in detail below in conjunction with the drawings.

[0022] Refer to Figure 1As shown in the figure, a material mixing system according to an exemplary embodiment of the present disclosure includes a stirring device and at least two material conveying devices. The stirring device includes a stirring barrel 1, a stirring mechanism, and a driving mechanism 8 for driving the operation of the stirring mechanism. The stirring mechanism is arranged inside the stirring barrel 1, and the driving mechanism 8 passes through the stirring barrel 1 and is connected to the stirring mechanism. The stirring barrel 1 is provided with a discharge port 12 and a plurality of feed ports 11, and the stirring barrel 1 is supported by a hydraulic lifting column 5; the material conveying device includes a material storage container, a material conveying pipeline, and a material detection mechanism. The input port of the material conveying pipeline is communicated with the material storage container, the output port of the material conveying pipeline is communicated with the feed port 11, and the material detection mechanism is connected to the material conveying pipeline for detecting and controlling the feeding amount of the material.

[0023] In this embodiment, the material conveying device can convey liquids, solids, gases, etc. Two or more material conveying devices can be provided according to actual needs, and specifically whether to convey liquids, solids or gases can be combined according to the product to be prepared. A plurality of feed ports 11 are provided on the stirring barrel 1, and the number of feed ports 11 to be used is specifically selected according to the types of raw materials required to adapt to different usage situations. The hydraulic lifting column 5 includes a hydraulic cylinder, a hydraulic pump, a control valve, and hydraulic oil. The inside of the hydraulic cylinder includes a piston and a sealing device, and the reciprocating movement of the piston is realized by the push of the hydraulic oil. The hydraulic pump provides a power source for the hydraulic cylinder, sucks the hydraulic oil into the pump body through a suction action, and compresses it inside the pump body to form high-pressure oil; the control valve is installed in the hydraulic system for controlling the flow direction, pressure, and flow rate of the hydraulic oil, so as to achieve precise control of the movement of the hydraulic lifting column 5. Therefore, the hydraulic lifting column 5 can adapt to the ground in different situations, control the lifting of each hydraulic lifting column 5 according to the flatness of the ground, and ensure that the stirring device is in a horizontal posture. After stirring is completed, the angle of the stirring device can be adjusted by adjusting the hydraulic lifting column 5 to facilitate the complete discharge and cleaning of the stirred product, preventing residues from corroding the stirring barrel 1.

[0024] In summary, since the material mixing system includes at least two material conveying devices, and the material storage container of the material conveying device is connected to the stirring device through the material conveying pipeline, at least two materials can be mixed and stirred simultaneously; since the material conveying pipe is connected with a material detection mechanism, the ratio relationship between multiple materials can be automatically controlled by detecting the change amount of the material; the stirring barrel 1 is supported by the hydraulic lifting column 5, which can not only adapt to different ground environments, eliminate the influence of ground flatness on the operation of the stirring device, but also tilt the angle of the stirring barrel 1 by controlling the hydraulic lifting column 5 to facilitate the complete discharge of the material in the stirring barrel 1, thereby improving the overall working efficiency of the material mixing system.

[0025] In an implementable embodiment, the stirring mechanism includes a stirrer 2. The stirrer 2 includes a stirring shaft 21 parallel to the axis of the stirring barrel 1 and a plurality of stirring parts 22 distributed along the axial direction of the stirring shaft 21. A high-frequency vibrator 23 is provided on the stirring shaft 21.

[0026] In this embodiment, the driving mechanism 8 is connected to the stirring shaft 21. The driving mechanism 8 can specifically be a motor for controlling the rotation of the stirring shaft 21. The stirring part 22 can include, but is not limited to, blades, spiral blades, or stirring rods perpendicular to the stirring shaft 21, etc. In the present disclosure, taking the preparation of a curing agent as an example, during the stirring process, the high-frequency vibration generated by the high-frequency vibrator 23 is used to prevent the curing agent from sticking to the inner wall of the stirring barrel 1, avoiding inconvenience in cleaning. When cleaning the stirring barrel 1, the high-frequency vibrator 23 can also play a role, optimizing the cleaning degree and preventing the curing agent from curing and affecting the next use.

[0027] In an implementable embodiment, the stirring mechanism includes two stirrers 2. The stirrer 2 includes a stirring shaft 21 parallel to the axis of the stirring barrel 1 and a plurality of stirring parts 22 distributed along the axial direction of the stirring shaft 21. A high-frequency vibrator 23 is provided on the stirring part 22. Among them, the rotation directions of the two stirring shafts 21 are opposite.

[0028] In this embodiment, by controlling the rotation directions of the two stirring shafts 21 to be opposite, the stirring efficiency and effect are improved, making the stirring more thorough. In order to enable the two stirring shafts 21 to rotate in different directions, the driving mechanism 8 can specifically be a bevel gear transmission structure. The design of the bevel gears enables the power to be transmitted in the vertical direction, and through the meshing between the bevel gears, the reverse synchronous operation of the two shafts is achieved. Specifically, two bevel gears with opposite fixed directions are arranged on the same power shaft, and the power shaft and the stirring shaft 21 meet the perpendicular condition. Then, these two bevel gears are respectively meshed with the bevel gears arranged on the two stirring shafts 21, thereby driving the two stirring shafts 21 to rotate in reverse synchronously. The driving mechanism 8 can also be motors respectively connected to the two stirring shafts 21, and the two motors respectively control the two stirring shafts 21 to achieve reverse rotation. In addition, the driving mechanism 8 can also be a gear transmission structure. In order to achieve the reverse rotation of the two stirring shafts 21, the primary gear and the secondary gear can be installed on their respective stirring shafts 21. In this way, when the primary gear rotates clockwise, due to the effect of the tooth number ratio and the meshing method, the secondary gear will rotate counterclockwise. It can be understood that the driving mechanism 8 is not limited to the above several forms, as long as it satisfies the condition that the rotation directions of the two stirring shafts 21 are opposite. The stirring part 22 can include but is not limited to blades, spiral blades, or stirring rods perpendicular to the stirring shaft 21, etc. During the stirring process, the high-frequency vibrator 23 generates high-frequency vibration to prevent the curing agent from adhering to the inner wall of the stirring barrel 1, avoiding inconvenience in cleaning. When cleaning the stirring barrel 1, the high-frequency vibrator 23 can also play a role, optimizing the cleaning degree and preventing the curing agent from solidifying and affecting the next use.

[0029] In an implementable embodiment, a plurality of water spray nozzles 24 are formed on the stirring part 22, and the plurality of water spray nozzles 24 are evenly distributed on the stirring part 22.

[0030] In this embodiment, the stirring shaft 21 can be a hollow water storage structure, the stirring part 22 is communicated with the stirring shaft 21, the water spraying system further includes a water tank, a water pump, and a high-pressure water pipe. The water pump provides high-pressure water source for the water spraying system to ensure that the water flow can be sprayed out with sufficient pressure. The high-pressure water pipe connects the water tank and the water pump and conveys the high-pressure water flow to the water spray nozzles 24 on the stirring part 22 to spray high-pressure water flow. These high-pressure water flows impact the inner wall of the stirring barrel 1 at an extremely high speed, and cooperate with the high-frequency vibrator 23 to jointly clean the stirring barrel 1 in a timely manner, saving manpower without affecting the next use, and improving the use efficiency and service life of the machine. It can be understood that the water spray nozzles 24 can be designed into different shapes and sizes according to needs to adapt to different cleaning environments. In addition, the water spraying system further includes a control system, and the control system is used to control parameters such as the start and stop, water spraying time, and water spraying intensity of the water spraying system to ensure that the water spraying process can proceed according to the preset program.

The input port of the solid conveying pipeline 42 communicates with the solid storage container 41, and the output port of the solid conveying pipeline 42 communicates with another one of the plurality of feeding ports 11.

[0032] In this embodiment, the input ports of both the liquid conveying pipeline 32 and the solid conveying pipeline 42 should be higher than the output ports, that is, to ensure that the materials can smoothly flow from the material storage container into the mixing barrel 1 along the material conveying pipeline in a downward inclined manner.

[0033] In an implementable embodiment, the material conveying device further includes a pump station, and the pump station is connected to the material conveying pipeline.

[0034] In this embodiment, the input ports of the liquid conveying pipeline 32 and the solid conveying pipeline 42 do not need to be higher than the output ports, that is, the material conveying pipeline can be inclined from the material storage container towards the mixing barrel 1 which is inclined upwards. The pump station can provide a power source for the material conveying pipeline to push the materials forward.

[0035] Furthermore, in an implementable embodiment, the material detection mechanism includes a liquid detection mechanism 33. The liquid detection mechanism 33 is arranged inside the liquid conveying pipeline 32 and is used to detect the liquid flow rate passing through the liquid detection mechanism 33 and control the liquid feeding amount of the liquid material.

[0036] In this embodiment, the liquid detection mechanism 33 can specifically be, including but not limited to, an ultrasonic flowmeter, an electromagnetic flowmeter, a vortex street flowmeter or a mass flowmeter, etc. Among them, the ultrasonic flowmeter measures the flow rate of the fluid by using the time difference of ultrasonic waves propagating in the liquid, and then calculates the flow rate; the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction and calculates the flow rate by measuring the induced electromotive force generated by the conductive liquid moving in the magnetic field; the vortex street flowmeter sets a bluff body in the fluid. When the fluid passes through, regular vortices are alternately generated on both sides of the bluff body, and the flow rate is deduced by measuring the shedding frequency of the vortices; the mass flowmeter directly obtains the flow rate data by measuring the liquid flow rate of the liquid passing through the liquid conveying pipeline 32 per unit time.

[0037] In an implementable embodiment, the material detection mechanism further includes a solid detection mechanism 43. The solid detection mechanism 43 is connected to the solid storage container 41 and is used to detect the mass change of the solid material in the solid storage container 41 and control the feeding amount of the solid material.

[0038] In an implementable embodiment, the solid conveying device 4 further includes a conveying mechanism 6 disposed beside the solid storage container 41. The conveying mechanism 6 includes a plurality of transmission shafts 61 and a conveyor belt 62 sleeved on the plurality of transmission shafts 61. The conveyor belt 62 is used to convey solid materials into the solid storage container 41.

[0039] In this embodiment, the operation process of the material mixing system is as follows: Solid materials are conveyed by the conveyor belt 62 into the solid storage container 41 for temporary storage, and then transported into the mixing barrel 1 through the solid conveying pipeline 42. Meanwhile, the solid detection mechanism 43 detects the change in the mass of the solid materials to control the mass of the solid materials entering the mixing barrel 1. At the same time, the liquid materials are pre-temporarily stored in the liquid storage container 31 and then input into the mixing barrel 1 through the liquid conveying pipeline 32. Meanwhile, the liquid detection mechanism 33 detects the flow rate of the input liquid to control the liquid materials entering the mixing barrel 1. During the stirring process of the stirrer 2, the high-frequency vibrator 23 operates to continuously vibrate the stirrer 2 and the mixing barrel 1 to prevent the adhesion of the curing agent. After stirring is completed, the hydraulic lifting column 5 is controlled to tilt the angle of the mixing barrel 1 so that the stirring product can be completely discharged. After the work is completed, the mixing barrel 1 maintains a certain angle, the stirrer 2 rotates slowly, and at the same time, the high-frequency vibrator 23 and the water spraying system start to work to clean the used mixing barrel 1, and then the residue is discharged through the discharge port 12 after removing the discharge pipe. In the material mixing system, the mixing device and the plurality of material conveying devices can be detachably assembled to facilitate the movement of the machine and later inspection and replacement.

[0040] In an implementable embodiment, the material mixing system further includes a carrying device 7. The carrying device 7 includes a carrying platform 71 and a plurality of support columns 72 for supporting the carrying platform 71. The material conveying device is located on the carrying platform 71. The support columns 72 can also be replaced by the hydraulic lifting columns 5 as needed, which will not be elaborated here.
