Description

Technical Field

[0001] The invention belongs to the technical field of slurry kneading, and in particular relates to an automatic feeding and stirring control system for slurry production. Background Art

[0002] Wet-process slurry production is an important step in the production of metallic pigments. Existing wet-process slurry production is usually processed by traditional manual feeding and manual control. The operator stirs and mixes the slurry through the slurry production system, which is usually a kneading machine. The operator adjusts the speed and timing of the kneading machine based on experience, and then manually shovels the slurry into the barrel of the kneading machine. The kneading machine stirs the slurry at the adjusted speed to complete the slurry production process.

[0003] However, there are some shortcomings in the traditional slurry production system. First, the manual control of the speed and timing of the kneading machine is easily limited by the operator's experience, resulting in unstable slurry quality each time, which will bring hidden dangers to product quality during the production process and cannot guarantee the safety of production. Furthermore, during the feeding process, the feeding position of manual barreling is relatively high, which is prone to dust, which not only affects the production environment, but also may pose a hidden danger to the health of operators. In addition, since the slurry loaded in this type of slurry production system is usually a highly viscous metallic pigment semi-finished product, it is difficult to barrel the slurry, and the feeding rate is low. Therefore, it is urgent to develop an automatic feeding and stirring control system for slurry production to replace the existing slurry production system, improve production efficiency, ensure production safety, and ensure the consistency of slurry quality. Summary of the invention

Before feeding, the agitator is coupled with the stirring barrel and drives the stirring barrel to tilt; when feeding, the agitator is decoupled from the stirring barrel and guides the slurry into the stirring barrel, and the positioning member maintains the tilted posture of the stirring barrel during the feeding process. After the feeding is completed, the agitator is coupled with the stirring barrel again, and the positioning member releases the restriction on the posture of the stirring barrel, and the agitator drives the stirring barrel to reset, and then the agitator is decoupled from the stirring barrel again, and can independently rotate and stir the slurry, thereby processing the slurry into a finished metallic pigment product.

[0008] As a further optimization scheme of the present invention, the agitator also includes several groups of connecting rods distributed axially along the stirring shaft, and multiple columnar stirring paddles are arranged between adjacent groups of connecting rods. Spiral stirring blades are arranged on the outside of the stirring shaft, and the spiral stirring blades are connected to the stirring shaft through connecting rods.

[0011] As a further optimization scheme of the present invention, a guide channel is provided at one end of the socket away from the U-shaped barrel, the annular air channel of the air supply and exhaust ring at the end of the loading ring is connected to the guide channel in the loading ring, and an air guide port is provided on one side of the annular air channel, and the air guide port is used to connect the joint with the corresponding annular air channel.

[0012] As a further optimization solution of the present invention, the positioning member includes a linear drive member, a positioning column fixed to the output end of the linear drive member, and a positioning hole corresponding to the positioning column is provided at the end of the U-shaped barrel.

[0013] As a further optimization scheme of the present invention, the system also includes a spraying mechanism, which includes a dosing pipe arranged above the U-shaped barrel, a liquid distribution pipe connected to the outlet of the dosing pipe, a plurality of nozzles evenly distributed at the bottom of the liquid distribution pipe, and a dosing pump for supplying liquid to the dosing pipe.

[0014] As a further optimization scheme of the present invention, the system also includes a frame, the frame has a first support and a second support, and a support frame fixed between the first support and the second support, and the U-shaped barrel is located on the inner side of the support frame; the spray mechanism also includes a lifting component fixed under the top wall of the support frame, and a cover plate fixed at the output end of the lifting component, and the liquid distribution pipe is fixed at the bottom of the cover plate.

[0015] As a further optimization scheme of the present invention, a temperature sensor is provided inside the U-shaped barrel, a flow meter is provided between the dosing pump and the dosing pipe, a position switch is provided on the cover plate, and a first valve for discharging and a second valve for circulating cleaning liquid are provided at the bottom of the U-shaped barrel; when the cover plate is away from the opening of the U-shaped barrel, or the second valve is opened, the agitator stops, and when the first valve is opened in a non-discharging state, the agitator stops.

[0016] The beneficial effects of the present invention are:

[0017] 1) The present invention controls the coupling or decoupling of the agitator and the mixing barrel through a coupling component, and fixes the tilted mixing barrel through a positioning member. Since the mixing barrel is U-shaped and tilted during feeding, the feeding position can be lowered and the receiving position can be raised, thereby reducing dust.

[0019] 3) The agitator of the present invention uses round steel as stirring paddles inside, and the number of round steel is large, which can effectively mix the slurry and avoid the surface of the slurry being damaged by traditional paddles. At the same time, the spiral stirring blades on the periphery can ensure the overall fluidity of the material and mix evenly without dead corners;

[0020] 4) In the production process of the present invention, a controller is used to regulate the agitator, the feeding mechanism, the driving mechanism and the spraying mechanism, so that the solid content of the slurry can be adjusted during the stirring process, the stability of the process parameters can be ensured, and the particle size of the metallic pigment processed from the slurry in each batch is consistent. Compared with the traditional manual timing speed regulation, it is more stable and convenient, and the equipment reliability is high;

[0021] 5) The present invention automatically feeds the material through the feeding mechanism, and after stirring, the first valve opens to automatically discharge the material, so as to carry out assembly line packaging of the metallic pigment, with high processing efficiency, saving time and labor;

[0022] 6) The present invention adopts a large amount of signal collection, which can effectively control the slurry temperature and spray rate. When the cover plate or the second valve is opened, the agitator stops, and when the first valve is opened in the non-discharging state, the agitator stops, which effectively ensures the safe operation of the equipment.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Example

[0036] like Figure 1-3As shown, this embodiment relates to an automatic feeding and stirring control system for slurry production, which includes a stirring barrel 1 and an agitator 2 that runs through the stirring barrel 1. The agitator 2 includes a rotating drive member 21 and a stirring shaft 22 fixedly arranged at the output end of the rotating drive member 21, and the rotating drive member 21 includes a motor and a reducer and a coupling arranged between the motor output shaft and the stirring shaft 22, as well as a speed sensor. The stirring barrel 1 is U-shaped as a whole and has an upper opening. A feeding mechanism 3 is provided on the front side of the stirring barrel 1, and the feeding mechanism 3 is preferably two mechanical arms. A feeding mechanism 9 is also provided on the front side of the stirring barrel 1, and the feeding mechanism 9 is used to transport a slurry container S containing slurry, and the slurry is a semi-finished metallic pigment with high viscosity. A handle is provided on one side of the slurry container S, and an anti-slip groove is provided on the handle. The above-mentioned mechanical arm can clamp the handle of the slurry container S through its clamping claws and perform feeding operations. The mechanical arm is also provided with a camera, which can realize the recognition of the slurry container S and the stirring barrel 1 to ensure that the feeding mechanism 3 can complete automatic feeding. The feeding mechanism 9 is preferably a chain conveyor, and a guide plate is provided on the side of the chain conveyor close to the mixing barrel 1, and the guide plate can align the slurry container S to ensure that the robot arm can smoothly grab the slurry container S. In addition, in some other embodiments, the feeding mechanism 9 may not be provided, and several slurry containers S may be placed around the robot arm. A material pump capable of pumping high-viscosity materials and related pipelines may also be used instead of the robot arm to realize automatic feeding of the slurry.

[0037] The system also includes a controller for regulating the working state of the agitator 2, and the motor and speed sensor of the agitator 2 are connected to the PLC controller. A coupling component 4 is provided between the mixing barrel 1 and the agitator 2, and a driving mechanism 5 is provided on the front side of the mixing barrel 1. The driving mechanism 5 is used to drive the coupling component 4 to couple and decouple the mixing barrel 1 and the agitator 2. Two pairs of positioning members 6 are also provided on both sides of the length direction of the mixing barrel 1. The positioning members 6 are used to fix the posture of the mixing barrel 1 after the mixing barrel 1 is tilted. The controller is preferably a PLC controller. The driving mechanism 5, the feeding mechanism 3 and the feeding mechanism 9 are all connected to the PLC controller. The system dispatches the agitator 2, the feeding mechanism 3, the driving mechanism 5 and the feeding mechanism 9 through the PLC controller to realize automatic feeding and automatic stirring of slurry production. The agitator 2 also includes a plurality of groups of connecting rods 23 distributed axially along the agitator shaft 22. The ends of the connecting rods 23 are fixed to the agitator shaft 22. A plurality of columnar agitating paddles 24 are fixed between adjacent groups of connecting rods 23. The columnar agitating paddles 24 are preferably round steel. A spiral agitating blade 25 is provided on the outside of the agitator shaft 22. The spiral agitating blade 25 is connected to the agitator shaft 22 through the connecting rod 23.

[0038] Before feeding, the driving mechanism 5 couples the stirring shaft 22 of the stirrer 2 with the stirring barrel 1, that is, the stirring shaft 22 and the stirring barrel 1 are relatively fixed. The stirring shaft 22 drives the stirring barrel 1 to rotate, so that the stirring barrel 1 is tilted. When feeding, the feeding mechanism 9 operates intermittently to convey the slurry container S containing the slurry, and the slurry container S is moved to the top of the opening of the stirring barrel 1 through the two feeding mechanisms 3, and the slurry container S is rotated so that the slurry in the slurry container S falls into the stirring barrel 1. The stirring shaft 22 of the stirrer 2 is decoupled from the stirring barrel 1, that is, the stirring shaft 22 can rotate relative to the stirring barrel 1. The stirring shaft 22 rotates at a low speed, thereby guiding the slurry into the stirring barrel 1 through the connecting rod 23, the columnar stirring paddle 24 and the spiral stirring blade 25, so as to avoid the accumulation of the slurry with high viscosity on the upper part of the stirring barrel 1. The feeding mechanism 3 can greatly tilt the slurry container S to ensure that the slurry is quickly loaded into the stirring barrel 1 and avoid dust. During the feeding process, the positioning member 6 maintains the tilted posture of the mixing barrel 1 to ensure that the posture of the mixing barrel 1 can be fixed after the agitator 2 is decoupled from the mixing barrel 1. After the feeding is completed, the driving mechanism 5 drives the coupling component 4 again to couple the agitator shaft 22 of the agitator 2 with the mixing barrel 1 again. Then the positioning member 6 releases the restriction on the posture of the mixing barrel 1, and the agitator shaft 22 drives the mixing barrel 1 to rotate and reset, so that the opening of the mixing barrel 1 faces upward. After that, the driving mechanism 5 drives the coupling component 4 again to decouple the agitator shaft 22 from the mixing barrel 1 again. This allows the agitator 2 to operate independently, stir the slurry, and process the slurry into metallic pigments.

[0039] Specifically, Figure 4-7 As shown, the coupling assembly 4 includes a loading ring 41 fixedly mounted on the outside of the stirring shaft 22, a plurality of insertion holes 42 distributed along the circumference of the loading ring 41, and a plug 43 slidably mounted on the inside of the insertion hole 42. A fixing member 45 is fixedly mounted on the inside of the loading ring 41, and the fixing member 45 is fixedly connected to the stirring shaft 22. The fixing member 45 in this embodiment is welded to the stirring shaft 22. The loading ring 41 is fixed to the stirring shaft 22 by the fixing member 45. A sealing member is provided between the plug 43 and the insertion hole 42. The stirring barrel 1 includes a U-shaped barrel 11 and a connecting ring 12 provided at the end of the U-shaped barrel 11, and the connecting ring 12 is provided with a pin hole 13 corresponding to the plug 43 of the coupling assembly 4, and the plug 43 is clearance-matched with the pin hole 13, and the end of the plug 43 facing the pin hole 13 is chamfered. The U-shaped barrel 11 is composed of a U-shaped plate and two end plates fixed at both ends of the U-shaped plate in the length direction. When the U-shaped plate is tilted, it can receive the slurry through the side wall of its upper part to improve the material receiving position. When the driving mechanism 5 drives the latch 43 to insert into the pin hole 13 of the mixing barrel 1, the mixing barrel 1 is coupled with the agitator 2. When the driving mechanism 5 drives the latch 43 to leave the pin hole 13 of the mixing barrel 1, the mixing barrel 1 is decoupled from the agitator 2.

[0040] Both ends of the U-shaped barrel 11 are provided with connecting rings 12, and the system has two coupling components 4 corresponding to the connecting rings 12. The driving mechanism 5 includes a two-way pump 51, and a gas pipeline 52 connected to one port of the two-way pump 51, the gas pipeline 52 has two gas outlets, and joints 53 are provided on both gas outlets of the gas pipeline 52. The two-way pump 51 is preferably a Roots pump. The driving mechanism 5 also includes two air supply and exhaust rings 54, and the two air supply and exhaust rings 54 are respectively rotated to the ends of the loading rings 41 of the two coupling components 4 away from the U-shaped barrel 11. A sealing member is provided between the mutually connected air supply and exhaust rings 54 and the loading rings 41. The two loading rings 41 are respectively communicated with the two joints 53, and the inner sides of the two loading rings 41 are provided with an annular air channel 55, and the annular air channel 55 is used to connect the joints 53 with the corresponding sockets 42. The left joint 53 is connected to the socket 42 in the left loading ring 41, and the right joint 53 is connected to the socket 42 in the right loading ring 41. A guide channel 44 is provided at one end of the socket 42 away from the U-shaped barrel 11, and the annular air channel 55 of the air supply and exhaust ring 54 at the end of the loading ring 41 is connected to the guide channel 44 in the loading ring 41. An air guide port 56 is provided on one side of the annular air channel 55, and the air guide port 56 is used to connect the joint 53 with the corresponding annular air channel 55.

[0041] When the drive mechanism 5 drives the coupling assembly 4 to couple the agitator 2 with the mixing barrel 1, the agitator 2 makes the pin 43 in the loading ring 41 face the pin hole 13, and the two-way pump 51 inflates the annular air channel 55 of the air supply and exhaust ring 54 through the air supply pipeline 52 and the joint 53. After the gas in the annular air channel 55 enters the loading ring 41, a positive pressure is formed in the plug hole 42, and the pin 43 is pushed into the pin hole 13, completing the coupling of the agitator shaft 22 with the mixing barrel 1. When the drive mechanism 5 drives the coupling assembly 4 to decouple the agitator 2 from the mixing barrel 1, the two-way pump 51 evacuates the air supply pipeline 52, and the gas in the plug hole 42 passes through the guide channel 44, the annular air channel 55, the air guide port 56 and the joint 53 in sequence, and enters the air supply pipeline 52, and is discharged outward through the two-way pump 51, resulting in a negative pressure in the plug hole 42, sucking the pin 43 out of the pin hole 13, completing the decoupling of the agitator shaft 22 from the mixing barrel 1. In addition, in some other embodiments, the driving mechanism 5 may also be a driving device whose output end can move linearly back and forth.

[0042] The system also includes a frame 8, which has a first support 81 and a second support 82, and a support frame 83 fixed between the first support 81 and the second support 82, and the U-shaped barrel 11 is located inside the support frame 83. A positioning seat 57 is fixed at the bottom of the air supply and exhaust ring 54, and the positioning seats 57 on both sides of the length direction of the mixing barrel 1 are respectively fixed on the first support 81 and the second support 82, and the left joint 53 passes through the first support 81 and the left positioning seat 57 and is connected to the air supply and exhaust ring 54, and the right joint 53 passes through the second support 82 and the right positioning seat 57 and is connected to the air supply and exhaust ring 54.

[0043] like Figure 8 and Fig. 9 As shown, the positioning member 6 includes a linear drive member 61, a positioning column 62 fixed at the output end of the linear drive member 61, and a positioning hole 14 corresponding to the positioning column 62 is provided at the end of the U-shaped barrel 11. The positioning column 62 is loosely matched with the positioning hole 14, and the end of the positioning column 62 facing the U-shaped barrel 11 is chamfered. The first support 81 and the second support 82 are respectively provided with brackets 63 corresponding to the positioning columns 62 on both sides of the length direction of the mixing barrel 1. The positioning column 62 passes through the bracket 63. The bracket 63 can withstand the load of the mixing barrel 1 on the positioning column 62 to prevent the linear drive member 61 from being damaged. When the posture of the mixing barrel 1 is fixed, the positioning column 62 is opposite to the positioning hole 14, and the linear drive member 61 inserts the positioning column 62 into the positioning hole 14 of the mixing barrel 1. When the posture of the mixing barrel 1 is released, the linear drive member 61 pulls the positioning column 62 out of the positioning hole 14. The linear drive member 61 is preferably an electric push rod. In other embodiments, the electric push rod may also be replaced by a device with telescopic capability, such as a pneumatic cylinder or an oil cylinder.

[0044] For further information, see Fig.10 The system also includes a spray mechanism 7, which includes a dosing pipe 71 arranged above the U-shaped barrel 11, a liquid distribution pipe 72 connected to the outlet of the dosing pipe 71, a plurality of nozzles 73 evenly distributed at the bottom of the liquid distribution pipe 72, and a dosing pump for supplying liquid to the dosing pipe 71. The spray mechanism 7 also includes a lifting component 74 fixedly arranged below the top wall of the support frame 83, and a cover plate 75 fixedly arranged at the output end of the lifting component 74, and the liquid distribution pipe 72 is fixedly arranged at the bottom of the cover plate 75. The lifting component 74 is preferably an electric push rod. A guide member 76 is provided between the cover plate 75 and the top wall of the support frame 83, and the guide member 76 is preferably a telescopic tube composed of an inner tube and an outer tube. A temperature sensor is provided inside the U-shaped barrel 11, and a flow meter is provided between the dosing pump and the dosing pipe 71. The controller can adjust the rotation speed of the agitator 2 through the temperature information collected by the temperature sensor. When the temperature in the mixing barrel 1 is too high, the rotation speed of the agitator 2 is reduced. The controller also controls the dosing pump through the information transmitted by the flow meter, so that the spraying rate of the spraying mechanism 7 tends to a constant value. A position switch is provided on the cover plate 75, and a first valve 15 for discharging and a second valve 16 for circulating the cleaning liquid are provided at the bottom of the U-shaped barrel 11; when the cover plate 75 is away from the opening of the U-shaped barrel 11, or when the second valve 16 is opened, the agitator 2 stops, and when the first valve 15 is opened in a non-discharging state, the agitator 2 stops. A material receiving container is provided below the mixing barrel 1 to receive the metallic pigment flowing out of the first valve 15. A conveying device can also be provided below the mixing barrel 1, and the material receiving container is placed on the conveying device by a mechanical arm. As the conveying device operates, multiple material receiving containers sequentially receive the metallic pigment flowing out of the first valve 15.

[0045] Before the feeding operation, the spray mechanism 7 moves up the cover plate 75 and the liquid distribution pipe 72 under the cover plate 75 through the lifting component 74 to avoid the cover plate 75 and the liquid distribution pipe 72 interfering with the U-shaped barrel 11 when the mixing barrel 1 is rotated. After the mixing barrel 1 is reset, the lifting component 74 moves down the cover plate 75 to close the opening of the mixing barrel 1, and at this time, the lifting component 74 also cooperates with the guide member 76 to limit the cover plate 75 to the mixing barrel 1 to avoid the mixing barrel 1 from swinging during the mixing of the slurry. When the slurry is stirred, the dosing pump sprays the solvent into the mixing barrel 1 through the dosing pipe 71, the liquid distribution pipe 72 and the nozzle 73. In addition, the inlet of the dosing pump can also be connected to the multi-way valve, and the multi-way valve can be connected to multiple liquid storage containers. The multiple liquid storage containers are used to hold solvents, additives and additives, and the various liquids required for processing the slurry can be automatically sprayed into the mixing barrel 1 through the spray mechanism 7. In addition, in some other embodiments, the first valve 15 and the second valve 16 may not be provided. When discharging, a receiving container is arranged at the rear side of the mixing barrel 1, and the opening of the mixing barrel 1 is rotated backward by the stirrer 2 and tilted downward, so that the slurry flows into the receiving container to realize the discharging operation of the metallic pigment.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
