Description

Technical Field

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

[0002] As a core device in industrial production, mixers are widely used in fields such as food processing, chemical production, pharmaceutical mixing, and building material preparation. Its core function is to uniformly mix raw materials through mixing blades, and then complete the discharge of materials through a feeding device. However, the feeding devices of existing mixers still have significant defects in terms of structural design, material adaptability, and operation efficiency, which are specifically manifested in the following aspects: Existing feeding devices usually adopt a general-purpose blade design, which is difficult to adapt to materials with different physical properties. For example: 1. Insufficient material adaptability Powdery materials: Powders with strong fluidity are prone to generating dust due to air flow disturbance during the feeding process, causing environmental pollution and raw material loss; Granular materials: Brittle granules (such as pharmaceutical tablets, nut foods) are prone to breakage when directly contacting rigid metal blades, affecting the qualified rate of finished products; Fibrous materials: Long fiber substances (such as plant stalks, textile raw materials) are prone to winding around the blade shaft, resulting in blockage of the feeding port and even equipment shutdown.

[0003] Although some improvement schemes propose to increase scraping plates or vibration auxiliary devices, the structure is complex and it is difficult to achieve rapid switching, unable to meet the flexible requirements of multi-variety and small-batch production.

[0004] 2. High cleaning and maintenance costs In the pharmaceutical or food industry, strict requirements are imposed on the cleanliness of equipment. Traditional feeding devices need to be frequently disassembled for manual cleaning of blades and conveying pipelines, which takes up to 30 - 60 minutes each time. Some mixers use high-pressure water guns for rinsing, but the residual water stains may cause corrosion of metal parts or electrical system failures. In addition, the gaps between fixed blades and the cavity are prone to accumulating materials, forming stubborn dirt after long-term use, further increasing the maintenance difficulty.

[0005] In summary, the feeding devices of existing technologies have obvious deficiencies in terms of accuracy, speed regulation, and operation stability, and cannot meet the high standards of modern production. Therefore, it is necessary to develop a feeding device for a mixer and its control system to solve the above problems and improve the quality and efficiency of concrete production. Summary of the Invention

[0006] The object of the present invention is to provide a feeding device and its control system for a mixer to solve the problems raised in the above-mentioned background technology. The energy-saving mixing blades directly shorten the mixing time, reduce energy consumption waste, and lower the equipment maintenance frequency through three core directions: efficient mixing design, intelligent control, and material innovation, thereby comprehensively improving production efficiency.

Detailed implementation mode

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-6 , the present invention provides a technical solution: a feeding device and its control system for a mixer, including a mixing bin 1. A front-end feeding assembly is arranged on one side of the mixing bin 1. The front-end feeding assembly includes a first raw material tank 2 arranged on one side of the mixing bin 1. A first conduit 3 is arranged on the top of the first raw material tank 2. The feeding initial end of the first conduit 3 extends into the first raw material tank 2 and is connected to a first pump 4. The first pump 4 is fixed in the first raw material tank 2. The feeding end of the first conduit 3 is connected to the top of the mixing bin 1. The feeding system drives the first pump 4 to operate to transport the raw materials in the first raw material tank 2 into the first conduit 3, and the raw materials are transported into the mixing bin 1 through the first conduit 3. This process is used for transporting the first type of raw material; The first type of raw material includes paste-like substances such as cement mortar. A first energy-saving bin 5 is arranged on the conveying path of the first conduit 3. A paddle assembly 6 is arranged in the first energy-saving bin 5. The conveying system drives the paddle assembly 6 to operate to increase the speed of transporting the raw materials in the first conduit 3. Since the length value of the first conduit 3 is large and the entire raw material conveying process path is long, the purpose of setting the first energy-saving bin 5 is to reduce the power of the first pump 4 and also enable the raw materials to be smoothly transported into the mixing bin 1; First intelligent valves 7 are provided at both the raw material input end and the raw material output end of the first energy-saving bin 5. Both of the two first intelligent valves 7 are controlled by the conveying system. The first intelligent valves 7 integrate flow meters and are linked with the controller to achieve quantitative feeding. The raw materials transported via the first conduit 3 all 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 input end of the first energy-saving bin 5 is opened. When the first energy-saving bin 5 is filled with raw materials, the conveying system drives the first intelligent valve 7 at the raw material input end of the first energy-saving bin 5 to close, making the first energy-saving bin 5 sealed. Then, the conveying system drives the paddle assembly 6 to operate to stir the raw materials in the first energy-saving bin 5. The function of this stirring is to loosen the raw materials in the first energy-saving bin 5, making the stirring quality of the raw materials in the stirring bin 1 better and avoiding the adhesion of raw materials. The stirring duration of the paddle assembly 6 is preset in the conveying system, and different stirring durations are set according to different types of raw materials; A second raw material bin 8 is provided on one side of the first raw material bin 2. A second conduit 9 is provided at the top of the second raw material bin 8. The initial material conveying end of the second conduit 9 extends into the second raw material bin 8 and is connected to the second pump 11. The second pump 11 is fixed in the second raw material bin 8. The second conduit 9 is connected to a part of the first conduit 3 between the first energy-saving bin 5 and the stirring bin 1, and an intelligent multi-way valve 10 is provided at the connection part. A second energy-saving bin 12 is provided on the conveying path of the second conduit 9. A paddle assembly 6 is also provided in the second energy-saving bin 12. The material conveying process of the second conduit 9 is the same as that of the first conduit 3, and the operating processes of the first energy-saving bin 5 and the second energy-saving bin 12 are the same. The conveying system drives the first conduit 3 and the second conduit 9 to alternately convey raw materials. 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 intelligent multi-way valve 10 is controlled by the conveying system throughout the process. The purpose of this process is to ensure that the part of the first conduit 3 between the first energy-saving bin 5 and the stirring bin 1 is always filled with raw materials, maintaining the stable performance of the raw material conveying in the stirring bin 1; Second intelligent valves 21 are provided at both the raw material input end and the raw material output end of the second energy-saving bin 12. Both of the two second intelligent valves 21 are controlled by the conveying system. The raw materials transported via the second conduit 9 all need to be conveyed into the second energy-saving bin 12. At this time, the second intelligent valve 21 at the raw material output end of the second energy-saving bin 12 is closed, and the second intelligent valve 21 at the raw material input end of the second energy-saving bin 12 is opened. When the second energy-saving bin 12 is filled with raw materials, the conveying system drives the second intelligent valve 21 at the raw material input end of the second energy-saving bin 12 to close, making the second energy-saving bin 12 sealed. Then, the conveying system drives the paddle assembly 6 to operate to stir the raw materials in the second energy-saving bin 12. The function of this stirring is to loosen the raw materials in the second energy-saving bin 12, making the stirring quality of the raw materials in the stirring bin 1 better and avoiding the adhesion of raw materials. The stirring duration of the paddle assembly 6 is preset in the conveying system, and different stirring durations are set according to different types of raw materials; For easily caking or sticky raw materials, 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; The above-mentioned first conduit 3 and second conduit 9 alternately match the raw material conveying frequency with the stirring duration of the paddle assembly 6; Both the first pump 4 and the second pump 11 are controlled by the conveying system and can perform quantitative raw material conveying to ensure that the raw materials conveyed into the first energy-saving bin 5 and the second energy-saving bin 12 each time are the preset quantity H1; Pressure sensors 22 are arranged on the inner side walls of the raw material output ends of the first energy-saving bin 5 and the second energy-saving bin 12. The pressure sensors 22 transmit data to the conveying system. The conveying system presets a rated pressure value L. If the pressure sensors 22 detect that the rated pressure value L is not reached when the raw materials are conveyed into the first energy-saving bin 5 or the second energy-saving bin 12, the conveying system conveys the preset quantity H2 into the first energy-saving bin 5 and the second energy-saving bin 12 again. H2 is much smaller than H1, and H2 is used as the raw material supplementary preset quantity to ensure the stability of the raw material quantity in the first energy-saving bin 5 and the second energy-saving bin 12; The raw material storage quantity of the first energy-saving bin 5 is a fixed quantity each time. Each time the raw materials stirred evenly by the paddle assembly 6 are output by the first intelligent valve 7 at the opened raw material output end. Repeat the process of stirring the raw materials in the first energy-saving bin 5, so that the raw materials conveyed to the stirring bin 1 through the first conduit 3 are in a loose state, and this way of conveying raw materials can ensure that the error of the raw material quantity entering the stirring bin 1 is extremely small. The traditional raw material conveying mode adopts the way of continuously conveying raw materials, and the unstable raw material conveying rate leads to the inability to accurately control the raw material conveying quantity; 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 columns 13 arranged on one side of the stirring bin 1. First motors 14 are installed at the tops of the columns 13. The output ends of the first motors 14 are fixedly installed with support plates 15. Three long plates 16 are evenly extended outward on the side wall surfaces of the support plates 15. The ends of the three long plates 16 are respectively fixedly installed with a first shell 17, a second shell 18, and a third shell 19. The paddle assembly 6 is arranged in the first shell 17, the second shell 18, and the third shell 19. The paddle assembly 6 includes an axial-flow paddle, a radial-flow paddle, and an airfoil paddle. The three types of paddles are all structures of existing technologies. Different types of paddle assemblies 6 have different processing procedures for different raw materials. For example, for fragile raw materials (such as brittle particles), the axial-flow paddle can reduce the breakage rate and ensure the integrity of the finished product; Characteristics of the axial-flow paddle: The blade inclination angle is large, which can push the fluid to flow axially. It is suitable for low-viscosity liquids, has low energy consumption and high mixing efficiency, and is commonly used in large storage tanks or sewage treatment.

[0021] Characteristics of radial-flow blades: The blades are perpendicular to the rotation axis, pushing the fluid to flow radially. They are suitable for high-viscosity media and adopt a multi-layer combined design to enhance the shear force while reducing power loss.

[0022] Characteristics of airfoil blades: The streamlined design imitates the wings of an airplane, reducing the generation of eddy currents and energy loss. The above are the explanations of three types of blades, and each type of blade has detachable blades, which is convenient for maintenance and partial replacement, and prolongs the service life. Support rods 20 are provided at both ends of the blade assembly 6 and are connected inside the first housing 17, the second housing 18, and the third housing 19 through the support rods 20. Connection ports 23 matching the intelligent valves (the intelligent valves here and in the subsequent paragraphs of this section are the above-mentioned first intelligent valve 7 and second intelligent valve 21) are provided at both ends of the first housing 17, the second housing 18, and the third housing 19. The connection port 23 is a combined structure, including a metal short tube 24 fixedly installed on the first housing 17, the second housing 18, and the third housing 19. A chute 25 is provided on a part of the outer side wall of the metal short tube 24. A sealing tube 26 is slidably connected to the chute 25. A rubber layer 27 is provided at the end of the sealing tube 26. The sealing tube 26 matches the specification of the intelligent valve. The conveying system drives the sealing tube 26 to move along the chute 25, thereby realizing the connection and disconnection between the sealing tube 26 and the intelligent valve. In the initial state, the sealing tube 26 and the intelligent valve are in a disconnected state, which is convenient for cleaning and maintenance of the first energy-saving bin 5 and the second energy-saving bin 12. In the state where the sealing tube 26 and the intelligent valve are disconnected, the conveying system drives the first motor 14 to operate. 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. The rotation of the long plate 16 drives the first housing 17, the second housing 18, and the third housing 19 to rotate. The conveying system drives the first housing 17, the second housing 18, and the third housing 19 to rotate to select a suitable blade assembly 6 for raw material conveying. Different types of blade 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, achieve targeted adaptation of the raw materials. At the same time, the adapted blade assembly 6 can reduce the overall load of the equipment and lower energy consumption.

[0023] Water tanks 33 are provided on one side of the first raw material tank 2 and the second raw material tank 8. A third conduit 34 is provided at the top of the water tank 33. The output port of the third conduit 34 matches the specification of the connection 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 conveying system drives the third pump 35 to operate. When the third pump 35 operates, the water in the water tank 33 is conveyed into the third conduit 34, and then conveyed through the third conduit 34 into the first housing 17, the second housing 18, and the third housing 19 connected to the third conduit 34, thereby cleaning the paddle assemblies 6 in the first housing 17, the second housing 18, and the third housing 19. While one set of paddle assemblies 6 is in use, another set of used paddle assemblies 6 can be cleaned. The used paddle assemblies 6 are cleaned in a timely manner to prevent the raw materials from solidifying on the paddle assemblies 6 and causing damage to the paddle assemblies 6; The first raw material tank 2 and the second raw material tank 8 are both replenished and replaced with raw materials by an external feeding mechanism. In this embodiment, the feeding mechanism is a prior art and will not be elaborated here.

[0024] A main pipe 28 is provided at the bottom of the mixing chamber 1. A third intelligent valve 31 is provided on the main pipe 28. The bottom end of the main pipe 28 is connected to a central pipe 29. A number of movable storage tanks 30 are provided on the side of the central pipe 29. A number of intelligent pump feeders 32 are evenly provided on the side wall of the central pipe 29. Each intelligent pump feeder 32 is connected to a storage tank 30. The medium completed by mixing in the mixing chamber 1 is conveyed into the central pipe 29 through the main pipe 28. The conveying system drives the intelligent pump feeders 32 to convey the medium in the central pipe 29 to the corresponding storage tanks 30. When the storage tanks 30 are full, they are transported away by manual handling or forklift handling from the outside, and the empty storage tanks 30 are replaced. The conveying system drives the intelligent pump feeders 32 to operate in sequence according to the preset process, so that the storage tanks 30 can be recycled; The intelligent pump feeder 32 is a prior art structure and will not be elaborated here.
