Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a stirring device capable of realizing automatic proportioning of catalytic liquid. Background Art

[0002] In the fields of coal mining and storage, in order to prevent coal from spontaneous combustion, it is often necessary to use an inhibitor liquid to treat the coal. The inhibitor liquid is a liquid used to prevent coal from spontaneous combustion. During the coal mining and storage process, there is a risk of coal spontaneous combustion due to the characteristics of the coal itself and environmental factors. The inhibitor liquid reduces the possibility of coal spontaneous combustion by inhibiting the oxidation reaction of the coal. Most inhibitor liquids are made by manually mixing and stirring a variety of chemical substances.

[0003] However, the accuracy of the current manual proportioning of the retardant solution is difficult to guarantee, and due to the uneven experience and skill levels of operators, errors are prone to occur during the proportioning process, resulting in unstable concentration of the retardant solution. Too high a concentration may cause waste and may also have a negative impact on the performance of the coal, while too low a concentration cannot achieve effective fire retardant effect.

[0004] Secondly, manual mixing is inefficient, consuming a significant amount of time and manpower, and resulting in uneven mixing, which impacts the quality of the catalyst solution. This is especially true in large-scale coal processing scenarios, where manual mixing cannot meet the demands of rapid production.

[0005] In addition, manual operation also has safety risks. During the mixing process, operators may be exposed to chemical substances, which may harm their health. At the same time, the operation of the mixing equipment may also cause accidental injuries to the operators.

[0006] Therefore, how to provide a stirring device that can achieve automatic proportioning of the catalytic liquid is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

The utility model can automatically control the automatic feeding device and the automatic stirring device to perform feeding and stirring operations, so that the proportioning and stirring and mixing work can be automatically completed with high precision. When stirring is performed using stirring blades composed of three groups of opposite inward-rotating ascending plates and outward-rotating descending plates, the solute can be rotated clockwise in the horizontal direction and can also be rotated in the vertical direction at the same time, thereby greatly improving the mixing efficiency and quality.

[0008] According to an embodiment of the present invention, a stirring device capable of realizing automatic proportioning of a catalytic liquid comprises an automatic stirring device, an automatic feeding device and a controller;

[0009] The automatic stirring device is arranged below the discharge port of the automatic feeding device, and the automatic stirring device includes a stirring container and a stirring motor.

The stirring main shaft is installed with a driving force on the output shaft at the bottom of the stirring motor, and the stirring main shaft is vertically arranged in the stirring container. Three groups of branch connecting rods are fixedly welded to the bottom end of the stirring main shaft. An inward-rotating rising plate is fixedly installed on the side of the branch connecting rod close to the stirring main shaft, and an outward-rotating descending plate is fixedly installed on the side of the branch connecting rod away from the stirring main shaft.

[0010] Furthermore, the three groups of branch connecting rods are distributed at an average angle to the axis of the stirring main shaft, and the angle between each group of branch connecting rods is 120°.

[0011] Furthermore, the inward rotating ascending plate forms an angle of 20° to 25° with the horizontal direction of the branch connecting rod, and the outward rotating descending plate forms an angle of -20° to -25° with the horizontal direction of the branch connecting rod.

[0012] Furthermore, the inward-rotating ascending plate and the outward-rotating descending plate have the same length, and there is a gap between the inward-rotating ascending plate and the outward-rotating descending plate, and the distance of the gap is between one-third and two-thirds of the length of the inward-rotating ascending plate.

[0013] Furthermore, a liquid level detection device is provided on one side of the automatic stirring device, and a concentration detection device is provided on the other side of the automatic stirring device.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0026] Example 1

[0027] refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , a stirring device capable of realizing automatic proportioning of an inhibitory liquid, comprising an automatic stirring device 1, an automatic feeding device 2 and a controller 5;

[0028] The automatic stirring device 1 includes a stirring container 11 and a stirring motor 12. The stirring motor 12 is fixedly installed at the center of the top of the stirring container 11. The output shaft at the bottom of the stirring motor 12 is driven by a stirring main shaft 13, and the stirring main shaft 13 is vertically arranged in the stirring container 11. Three groups of branch connecting rods 14 are fixedly welded to the bottom end of the stirring main shaft 13. An inward rotating rising plate 15 is fixedly installed on the side of the branch connecting rod 14 close to the stirring main shaft 13, and an outward rotating descending plate 16 is fixedly installed on the side of the branch connecting rod 14 away from the stirring main shaft 13.

[0029] The three groups of branch connecting rods 14 are distributed at an average angle to the axis of the stirring main shaft 13, and the angle between each group of branch connecting rods 14 is 120°;

[0030] Secondly, the inward rotating ascending plate 15 forms an angle of 20° to 25° with the branch connecting rod 14 in the horizontal direction, and the outward rotating descending plate 16 forms an angle of -20° to -25° with the branch connecting rod 14 in the horizontal direction;

[0031] In addition, the inward-rotating ascending plate 15 and the outward-rotating descending plate 16 are of the same length, and there is a gap between the inward-rotating ascending plate 15 and the outward-rotating descending plate 16. The distance between the edge of the inward-rotating ascending plate 15 and the outward-rotating descending plate 16 is greater than 1 / 3 of the length of the plate and less than 2 / 3 of the length of the plate.

[0032] In this embodiment, when the stirring motor 12 is started, it can drive the stirring shaft 13, the branch connecting rod 14 and each group of blades to rotate. Since the inward rotating rising plate 15 and the outward rotating descending plate 16 have opposite angles to the horizontal direction, the solution close to the side of the stirring shaft 13 will be subjected to the upward lifting force exerted by the inward rotating rising plate 15, and the solution close to the outside will be subjected to the downward force exerted by the outward rotating descending plate 16. Therefore, while the solution rotates horizontally in the stirring container 11, the liquid close to the inside of the stirring shaft 13 in the vertical direction will move upward, while the solution close to the outside will move downward. The solution and solute can be disturbed in the vertical direction through the speed difference, so that it can be stirred in the vertical direction while stirring horizontally, thereby improving the stirring speed and uniformity.

[0033] Example 2

[0034] refer to Figure 1 , the automatic stirring device 1 is arranged below the discharge port of the automatic feeding device 2, and the automatic feeding device 2 adopts a spiral conveying structure to transport the solute;

[0035] Specifically, the automatic stirring device 1 is composed of a motor and an auger blade and other mechanisms. When the motor is started, the auger blade can be driven to rotate, thereby driving the solute to be transported from the bottom to the top, and finally falls into the automatic stirring device through the discharge port;

[0036] In this embodiment, the solute can be automatically fed into the automatic stirring device 1 through the automatic feeding device 2, and the automatic feeding device 2 can accurately control the mass of the transmitted solute according to the control instructions, thereby reducing labor intensity, and can accurately control the material usage and improve the feeding efficiency.

[0037] Example 3

[0038] refer to Figure 1-2 , a liquid level detection device 3 is provided on one side of the automatic stirring device 1, a concentration detection device 4 is provided on the other side of the automatic stirring device 1, and a power supply system and a logic control system are provided in the controller 5;

[0039] Among them, the automatic stirring device 1 and the automatic feeding device 2 are both connected to the power supply system signal in the controller 5, and the liquid level detection device 3 and the concentration detection device 4 are both connected to the logic control system signal in the controller 5;

[0040] In this embodiment, the controller 5 can perform logical control of automatic batching. The controller 5 can perform real-time regression calculation based on the liquid level (volume) of the stirring container 11 and the feedback value of the concentration detection device 4 to predict the amount of solute required to achieve the target concentration and target volume. The calculation processor then sends feedback instructions to the power supply system and each valve to realize automatic control of the automatic feeding device 2 and the automatic stirring device 1, thereby accurately controlling factors such as the amount of solute and solvent added and the stirring time.

[0041] Working principle: The solute can be automatically fed into the automatic stirring device 1 through the automatic feeding device 2, and the liquid level of the solute can be automatically detected according to the liquid level detection device 3. When each group of solutes is injected into the set threshold, the controller 5 can control the start and stop of the automatic feeding device 2 according to the feedback value, and can automatically start the automatic stirring device 1. At this time, the stirring motor 12 can start to drive the stirring main shaft 13 to rotate, and the three groups of branch connecting rods 14 at the bottom of the stirring main shaft 13 and each group of inner rotating rising plates 15 and outer rotating descending plates 16 are located in the stirring container 11 and rotate horizontally. At this time, the solute can be moved along the stirring container 11. The stirring is carried out in a clockwise rotation. At the same time, since the horizontal angles of the inwardly rotating ascending plate 15 and the outwardly rotating descending plate 16 are opposite, the inwardly rotating ascending plate 15 can drive the inner solute to move upward, and the outwardly rotating descending plate 16 can drive the outer solute to move downward, thereby realizing vertical circulation stirring of the solute in the stirring container 11. After stirring, the concentration of the solution is monitored in real time by the concentration detection device 4. When the concentration meets the set threshold, the stirring operation is completed and the solution can be discharged. When the concentration does not meet the requirements, the automatic feeding device 2 can be automatically controlled to add the corresponding raw materials and stir again until the concentration requirements are met.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
