Description

Technical Field

[0001] The present invention relates to the technical field of industrial mixing equipment, in particular to a mixer feeding device and a control system thereof. Background Art

[0002] As a core piece of industrial equipment, blenders are widely used in food processing, chemical production, pharmaceutical mixing, building materials preparation, and other fields. Their core function is to uniformly mix raw materials through agitator blades, followed by material discharge through a discharge device. However, existing blender discharge devices still have significant deficiencies in structural design, material adaptability, and operational efficiency, as shown in the following aspects:

[0003] Existing unloading devices usually use a universal blade design, which is difficult to adapt to materials with different physical properties. For example:

[0004] 1. Insufficient material adaptability

[0005] Powdered materials: Powders with high fluidity are prone to generate dust during the feeding process due to air flow disturbance, causing environmental pollution and raw material loss;

[0006] Granular materials: brittle particles (such as pharmaceutical tablets and nuts) are easily broken when in direct contact with rigid metal blades, affecting the qualified rate of finished products;

[0007] Fibrous materials: Long-fiber materials (such as plant stems and textile raw materials) can easily wrap around the blade shaft, causing blockage of the feed port or even equipment shutdown.

[0008] Although some improvement plans propose adding scrapers or vibration auxiliary devices, the structure is complex and difficult to achieve rapid switching, and cannot meet the flexible needs of multi-variety and small-batch production.

[0009] 2. High cleaning and maintenance costs

[0010] In the pharmaceutical and food industries, equipment cleanliness requirements are stringent. Traditional unloading systems require frequent disassembly of the impellers and conveying pipes for manual cleaning, which can take up to 30-60 minutes per cleaning. Some mixers use high-pressure water jets for flushing, but residual water stains can cause corrosion of metal components or electrical system failures. Furthermore, the gap between the fixed impellers and the chamber easily accumulates material, forming stubborn dirt over time and further complicating maintenance.

[0011] In summary, existing mixer discharging devices have significant deficiencies in accuracy, speed regulation, and operational stability, failing to meet the high standards of modern production. Therefore, it is necessary to develop a mixer discharging device and its control system to address these issues and improve the quality and efficiency of concrete production. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-6 The present invention provides a technical solution: a mixer unloading device and a control system thereof, comprising a mixing bin 1, a front-end unloading assembly being arranged on one side of the mixing bin 1, the front-end unloading assembly comprising a first raw material box 2 being arranged on one side of the mixing bin 1, a first conduit 3 being arranged on the top of the first raw material box 2, a feeding initial end of the first conduit 3 extending into the first raw material box 2 and connected to a first pump 4, the first pump 4 being fixed in the first raw material box 2, a feeding end of the first conduit 3 being connected to the top of the mixing bin 1, a feeding system driving the first pump 4 to operate to feed the raw material in the first raw material box 2 into the first conduit 3, and then feeding the raw material into the mixing bin 1 via the first conduit 3, this process being used to transport the first raw material;

[0035] The first raw material includes a slurry such as cement mixed mortar. A first energy-saving bin 5 is provided on the conveying path of the first conduit 3. A paddle assembly 6 is provided in the first energy-saving bin 5. The paddle assembly 6 is driven by the conveying system to increase the speed of the raw material conveyed in the first conduit 3. Since the first conduit 3 is long and the entire raw material conveying process is long, the purpose of providing the first energy-saving bin 5 is to reduce the power of the first pump 4 and to ensure smooth conveyance of the raw material into the mixing bin 1.

[0036] First intelligent valves 7 are provided at both the raw material conveying end and the raw material output end of the first energy-saving bin 5. Both first intelligent valves 7 are controlled by the conveying system. The first intelligent valves 7 are integrated with a flow meter and linked to the controller to realize quantitative feeding. The raw materials transported through the first conduit 3 need to be conveyed into the first energy-saving bin 5. At this time, the first intelligent valve 7 at the raw material output end of the first energy-saving bin 5 is closed, and the first intelligent valve 7 at the raw material conveying end of the first energy-saving bin 5 is opened. When the first energy-saving bin 5 is full of raw materials, the conveying system drives the first intelligent valve 7 at the raw material conveying end of the first energy-saving bin 5 to close, so that the first energy-saving bin 5 is closed. Then the conveying system drives the paddle assembly 6 to stir the raw materials in the first energy-saving bin 5. The function of this stirring is to stir and loosen the raw materials in the first energy-saving bin 5, so that the stirring quality of the raw materials in the stirring bin 1 is better and the raw materials are prevented from sticking. The stirring time of the paddle assembly 6 is preset in the conveying system, and different stirring times are set according to different types of raw materials.

[0037] A second raw material box 8 is provided on one side of the first raw material box 2, and a second conduit 9 is provided on the top of the second raw material box 8. The initial feeding end of the second conduit 9 extends into the second raw material box 8 and is connected to the second pump 11. The second pump 11 is fixed in the second raw material box 8. The second conduit 9 is connected to the portion of the first conduit 3 between the first energy-saving bin 5 and the mixing bin 1, and an intelligent multi-way valve 10 is provided at the connecting portion. A second energy-saving bin 12 is provided on the conveying path of the second conduit 9, and a paddle assembly 6 is also provided in the second energy-saving bin 12. The feeding process of the second conduit 9 is consistent with that of the first conduit 3, and the operation process of the first energy-saving bin 5 is consistent with that of the second energy-saving bin 12. The conveying system drives the first conduit 3 and the second conduit 9 to convey raw materials alternately. The function of the intelligent multi-way valve 10 is to cooperate with the alternating conveying process of the first conduit 3 and the second conduit 9. The entire intelligent multi-way valve 10 is controlled by the conveying system. The purpose of this process is to ensure that the portion of the first conduit 3 between the first energy-saving bin 5 and the mixing bin 1 is always full of raw materials, so as to maintain the stable performance of raw material conveying in the mixing bin 1;

[0038] Second smart valves 21 are provided at both the raw material delivery end and the raw material output end of the second energy-saving bin 12. Both second smart valves 21 are controlled by the conveying system. The raw materials transported through the second conduit 9 need to be transported into the second energy-saving bin 12. At this time, the second smart valve 21 at the raw material output end of the second energy-saving bin 12 is closed, and the second smart valve 21 at the raw material delivery end of the second energy-saving bin 12 is opened. When the second energy-saving bin 12 is full of raw materials, the conveying system drives the second smart valve 21 at the raw material delivery end of the second energy-saving bin 12 to close, so that the second energy-saving bin 12 is closed. Then the conveying system drives the paddle assembly 6 to stir the raw materials in the second energy-saving bin 12. The function of this stirring is to stir and loosen the raw materials in the second energy-saving bin 12, so that the stirring quality of the raw materials in the stirring bin 1 is better and the raw materials are prevented from sticking. The stirring time of the paddle assembly 6 is preset in the conveying system, and different stirring times are set according to different types of raw materials.

[0039] For raw materials that are prone to agglomeration or stickiness, the first energy-saving bin 5 and the second energy-saving bin 12 can prevent material blockage, ensure continuous production, and reduce the risk of blockage;

[0040] The first conduit 3 and the second conduit 9 alternately carry out raw material delivery at a frequency that matches the stirring duration of the blade assembly 6;

[0041] The first pump 4 and the second pump 11 are both controlled by the conveying system and can carry out quantitative raw material delivery, ensuring that the raw materials delivered to the first energy-saving bin 5 and the second energy-saving bin 12 each time are the preset quantitative H1;

[0042] A pressure sensor 22 is provided on the inner side wall of the raw material output end of the first energy-saving bin 5 and the second energy-saving bin 12. The pressure sensor 22 transmits data to the conveying system. The conveying system has a preset rated pressure value L. If the pressure sensor 22 detects that the rated pressure value L has not been reached when the raw material is conveyed into the first energy-saving bin 5 or the second energy-saving bin 12, the conveying system will again convey a preset quantity H2 into the first energy-saving bin 5 and the second energy-saving bin 12. H2 is much smaller than H1. H2 is used as the preset quantity to supplement the raw material. Its function is to ensure the stability of the raw material quantity in the first energy-saving bin 5 and the second energy-saving bin 12.

[0043] The first energy-saving bin 5 stores a fixed amount of raw materials each time. Each time the raw materials are evenly stirred by the paddle assembly 6, they are output through the first intelligent valve 7 at the opened raw material output end. The above process of stirring the raw materials in the first energy-saving bin 5 is repeated, so that the raw materials transported to the mixing bin 1 through the first conduit 3 are all in a loose state. This method of transporting raw materials can ensure that the error of the amount of raw materials entering the mixing bin 1 is extremely small. The traditional raw material transportation mode adopts a method of continuously transporting raw materials, and the raw material transportation rate is unstable, resulting in the inability to accurately control the raw material transportation amount.

[0044] The first energy-saving bin 5 and the second energy-saving bin 12 have the same structure. Taking the first energy-saving bin 5 as an example, the first energy-saving bin 5 includes a column 13 arranged on one side of the mixing bin 1, and a first motor 14 is installed on the top of the column 13. A support plate 15 is fixedly installed on the output end of the first motor 14. Three long plates 16 are evenly extended outward on the side wall of the support plate 15. The ends of the three long plates 16 are fixedly installed with a first shell 17, a second shell 18 and a third shell 19 respectively. The blade assembly 6 is arranged in the first shell 17, the second shell 18 and the third shell 19. The blade assembly 6 includes axial flow blades, radial flow blades and airfoil blades. The three blades are all existing technical structures. Different types of blade assemblies 6 have different processing processes for different raw materials. For example, for fragile raw materials (such as brittle particles), axial flow blades can reduce the breakage rate and ensure the integrity of the finished product;

[0045] Characteristics of axial flow impellers: The blades have a large inclination angle, which promotes the axial flow of the fluid. It is suitable for low-viscosity liquids, has low energy consumption, and high mixing efficiency. It is often used in large storage tanks or sewage treatment.

[0046] Features of radial impellers: The blades are perpendicular to the axis of rotation, promoting radial flow of the fluid. They are suitable for high-viscosity media and adopt a multi-layer combination design to enhance shear force while reducing power loss.

[0047] Features of airfoil blades: Streamlined design imitating aircraft wings, reducing vortex generation and energy loss;

[0048] The above is an explanation of the three types of blades, and each blade is detachable, which is convenient for maintenance and partial replacement, extending the service life;

[0049] Support rods 20 are provided at both ends of the blade assembly 6, which are connected to the first shell 17, the second shell 18 and the third shell 19 through the support rods 20. Connecting ports 23 matching the smart valves (the smart valves here and in the subsequent section are the first smart valve 7 and the second smart valve 21 mentioned above) are provided at both ends of the first shell 17, the second shell 18 and the third shell 19. The connecting port 23 is a combined structure, including a metal short tube 24 fixedly mounted on the first shell 17, the second shell 18 and the third shell 19. A slide groove 25 is provided on the outer wall of the metal short tube 24. A sealing tube 26 is slidably connected to the slide groove 25. A rubber layer 27 is provided at the end of the sealing tube 26. The sealing tube 26 matches the specifications of the smart valve. The conveying system drives the sealing tube 26 to move along the slide groove 25, thereby realizing the connection and connection between the sealing tube 26 and the smart valve. Disconnected. In the initial state, the sealing tube 26 and the smart valve are disconnected, which is convenient for cleaning and maintenance of the first energy-saving bin 5 and the second energy-saving bin 12. When the sealing tube 26 is disconnected from the smart valve, the conveying system drives the first motor 14 to operate, and the operation of the first motor 14 drives the support plate 15 to rotate. The rotation of the support plate 15 drives the long plate 16 to rotate, and the rotation of the long plate 16 drives the first shell 17, the second shell 18 and the third shell 19 to rotate. The conveying system drives the first shell 17, the second shell 18 and the third shell 19 to rotate to select the appropriate paddle assembly 6 for raw material conveying. Different types of paddle assemblies 6 can match the characteristics of the raw materials (such as viscosity, particle size, fluidity), improve the conveying speed and smoothness, avoid ineffective energy consumption, and achieve targeted adaptation of raw materials. At the same time, adapting the paddle assembly 6 can reduce the overall load of the equipment and reduce energy consumption.

[0050] A water tank 33 is provided on one side of the first raw material tank 2 and the second raw material tank 8. A third conduit 34 is provided on the top of the water tank 33. The output port of the third conduit 34 matches the specifications of the connecting port 23. The water delivery initial end of the third conduit 34 extends into the water tank 33 and is connected to the third pump 35. The delivery system drives the third pump 35 to operate. The third pump 35 operates to deliver the water in the water tank 33 into the third conduit 34, and then delivers the water into the first shell 17, the second shell 18 and the third shell 19 connected to the third conduit 34 through the third conduit 34, and then cleans the paddle assemblies 6 in the first shell 17, the second shell 18 and the third shell 19. While one group of paddle assemblies 6 is in use, the other group of used paddle assemblies 6 can be cleaned. The used paddle assemblies 6 are cleaned in time to avoid the raw materials solidifying on the paddle assemblies 6 and causing damage to the paddle assemblies 6.

[0051] The first raw material box 2 and the second raw material box 8 are both supplemented and replaced with raw materials by an external injection mechanism. In this embodiment, the injection mechanism is a prior art and will not be described in detail here.

[0052] A main pipe 28 is provided at the bottom of the mixing bin 1, and a third intelligent valve 31 is provided on the main pipe 28. The bottom end of the main pipe 28 is connected to the central pipe 29. A number of movable storage tanks 30 are provided on the side of the central pipe 29. A number of intelligent pumps 32 are evenly provided on the side wall of the central pipe 29. Each intelligent pump 32 is connected to a storage tank 30. The medium stirred by the mixing bin 1 is transported into the central pipe 29 through the main pipe 28. The conveying system drives the intelligent pump 32 to transport the medium in the central pipe 29 to the corresponding storage tank 30. When the storage tank 30 is full, it is transported manually by an outsider or by a forklift, and the full storage tank 30 is transported away and replaced with an empty storage tank 30. The conveying system drives the intelligent pump 32 to operate in sequence according to the preset process, so that the storage tank 30 can be recycled.

[0053] The intelligent pumping machine 32 is a conventional structure and will not be described in detail here.
