Description

Technical Field

[0001] The present invention relates to the technical field of purple sand clay refining, and specifically to a purple sand clay refining machine with a uniform batching structure. Background Art

[0002] Purple sand clay is the core raw material for making purple sand teapots. It is formed from inland lakes and coastal lagoon sedimentary deposits, buried deep in the mountain belly by external forces, and belongs to a special interlayer in the ridge clay ore layer. Purple clay, green clay, and red clay are the main categories of purple sand clay.

[0003] The mixing mechanism of traditional purple sand clay processing equipment relies on a single chamber or a simple stirring structure, resulting in uneven mixing of the clay due to gravity stratification or local retention. Moreover, the static extrusion method is difficult to refine the particles, and the highly viscous clay is prone to agglomeration. Secondly, the discharge control is extensive, lacking air flow assistance and dynamic pressure regulation, resulting in unstable discharge speed and easy blockage of the pipeline. At the same time, it is also difficult to flexibly adjust the process parameters according to the characteristics of the clay. Summary of the Invention

[0004] The purpose of the present invention is to provide a purple sand clay refining machine with a uniform batching structure to solve the problems mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A purple sand clay refining machine with a uniform batching structure, including a machine base. The bottom of the inner wall of the machine base is fixedly connected with a material cylinder through a support block. The top of the machine base is fixedly connected with an annular track. The top of the annular track is slidably connected with an annular rotating plate. The interior of the material cylinder is divided into chamber one and chamber two, and chamber one and chamber two are separated by a partition. Chamber one and chamber two are respectively divided into multiple refining chambers through multiple sets of sealing plates; Multiple sets of mounting frames are arranged in an annular array on the top of the annular rotating plate. The inner side of the mounting frame is fixedly installed with a central pipe and a material guiding pipe. Annular grooves are respectively opened at the top and bottom of the outer annular wall of the material cylinder. Annular sealing strips are slidably connected in the annular grooves. Through slots one and two are respectively opened at the corresponding positions of the material cylinder and the annular sealing strips. A through slot three is also opened on the side wall of the annular sealing strip located at the bottom of the outer annular wall of the material cylinder.

[0006] Furthermore, both ends of the central pipe are respectively communicated with the through slots two of the two annular sealing strips. One end of the material guiding pipe is communicated with the through slot three opened on the side wall of the annular sealing strip. Valve plates are respectively movably connected inside both ends of the central pipe and the end of the material guiding pipe close to the material cylinder through bearings. Motors for driving the corresponding valve plates to rotate are installed outside the central pipe and the material guiding pipe, and the motors are fixed on the outside of the mounting frame.

[0007] Further, a ring-shaped driving plate is fixedly connected to the bottom of the ring-shaped rotating plate, and driving grooves are equidistantly arranged on the outer side of the ring-shaped driving plate.

[0008] Further, a bracket is fixedly installed at the bottom of the barrel, and a rotating arm is movably connected inside the bracket through a bearing. One end of the rotating arm is fixedly installed with a driving block that cooperates with the driving groove, and a servo motor for driving the rotating arm to rotate is fixedly installed on the outer side of the bracket.

[0009] Further, electric push rods corresponding to the number of clay refining chambers are installed at both the top and the bottom of the barrel. A pressing plate is arranged inside the clay refining chamber, and the pressing plate is slidably connected inside the clay refining chamber in a form that completely fits the clay refining chamber. The output end of the electric push rod is fixedly connected to the pressing plate.

[0010] Further, central cylinders are arranged at the centers of the barrel inside both Chamber 1 and Chamber 2, and one end of the central cylinder is fixedly connected to the partition plate.

[0011] Further, ventilation holes matching the number of clay refining chambers are arranged on the outer side of one end of the central cylinder close to the partition plate. Ventilation pipes corresponding to the number of clay refining chambers are installed inside the central cylinder, and the air outlet ends of the ventilation pipes are hermetically connected to the ventilation holes.

[0012] Further, the air inlet end of the ventilation pipe extending to the outside of the barrel is communicated with an external air pump, and a one-way valve is installed at the air inlet end of the ventilation pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In terms of the mixing effect of the mud material, the design of multiple clay refining chambers realizes the repeated pushing of a small amount of purple sand mud in multiple spaces, enabling the mud material to alternately circulate between Chamber 1 and Chamber 2, avoiding the problem of uneven mixing in a traditional single chamber, greatly improving the mixing uniformity. The central pipes with different diameters cooperate with the dynamic pressure change and air flow pushing, causing a flow velocity difference and shear force of the mud material, breaking the mud mass structure, further refining the mud material particles, and enhancing the uniformity and fineness.

[0014] 2. In terms of the operating performance of the equipment, the segmented processing method of alternately pushing by multiple clay refining chambers effectively reduces the equipment load, avoids the long-term high-load operation of a single chamber, helps to extend the service life of the equipment. At the same time, each component works together to make the mud material flow and circulate quickly, improving the mixing efficiency. In terms of the discharging quality, after multiple squeezes, shears, and air flow dispersions, the finally discharged purple sand mud has a uniform structure and delicate texture, achieving uniform batching and better meeting the requirements of subsequent production processes.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0018] Embodiment 1: As Figures 1 - 7 shown, a purple sand clay refining machine with a uniform batching structure includes a machine base 1. The bottom of the inner wall of the machine base 1 is fixedly connected to a barrel 2 through a support block. The top of the machine base 1 is fixedly connected to an annular track 3. The top of the annular track 3 is slidably connected to an annular rotating plate 4. The interior of the barrel 2 is divided into a first chamber and a second chamber, and the first chamber and the second chamber are separated by a partition plate 5. The first chamber and the second chamber are respectively divided into multiple clay refining chambers by multiple groups of sealing plates 6; Multiple groups of mounting frames 8 are arranged in an annular array on the top of the annular rotating plate 4. The inner sides of the mounting frames 8 are fixedly installed with a central tube 901 and a material guiding tube 902. Annular grooves are respectively opened at the top and bottom of the outer annular wall of the barrel 2. An annular seal 10 is slidably connected in the annular groove. A first material passing groove and a second material passing groove are respectively opened at the positions corresponding to the barrel 2 and the annular seal 10. A third material passing groove is also opened on the side wall of the annular seal 10 located at the bottom of the outer annular wall of the barrel 2; It should be noted that although there are multiple central tubes 901 and they are connected to the corresponding clay refining rooms, the inner diameters of the respective central tubes 901 can be set differently. For example, the inner diameters of 6 central tubes 901 decrease in sequence. This design enables the purple sand clay in different clay refining rooms to have different flow rates and pressures due to the change in inner diameter when entering the central tube 901, forming a shear force, thereby initially breaking the clay mass structure and promoting the mixing of the purple sand clay.

[0019] Both ends of the central tube 901 are respectively connected to the second material passing groove of two annular seals 10 in a communicating manner. The connection parts between both ends of the central tube 901 and the second material passing groove of the two annular seals 10 are in sealed connection to avoid leakage. One end of the material guiding pipe 902 is connected to the third material passing groove opened on the side wall of the annular seal 10 in a communicating manner, and the connection part between the material guiding pipe 902 and the third material passing groove opened on the side wall of the annular seal 10 is in sealed connection to avoid leakage. Valve plates 11 are movably connected inside both ends of the central tube 901 and one end of the material guiding pipe 902 close to the barrel 2 through bearings. Motors for driving the corresponding valve plates 11 to rotate are installed outside the central tube 901 and the material guiding pipe 902, and the motors are fixed outside the mounting frame 8. An independent power source for driving the motors to operate is installed inside the mounting frame 8. It should be explained here that in the non-working state of the material guiding pipe 902, the valve plate 11 blocks the inside of the material guiding pipe 902.

[0020] An annular driving plate 12 is fixedly connected to the bottom of the annular rotating plate 4. Driving grooves 13 are equidistantly opened on the outside of the annular driving plate 12. A bracket is fixedly installed at the bottom of the barrel 2, and a rotating arm 14 is movably connected inside the bracket through a bearing. A driving block 15 matched with the driving groove 13 is fixedly installed at one end of the rotating arm 14, and a servo motor for driving the rotating arm 14 to rotate is fixedly installed outside the bracket.

[0021] Electric push rods 19 corresponding to the number of clay refining rooms are installed at both the top and the bottom of the barrel 2. A pressing plate 16 is arranged inside the clay refining room, and the pressing plate 16 is slidably connected inside the clay refining room in a form that completely fits the clay refining room. The output end of the electric push rod 19 is fixedly connected to the pressing plate 16.

[0022] Embodiment 2: Central tubes 7 are arranged at the center of the barrel 2 inside both the first chamber and the second chamber. One end of the central tube 7 is fixedly connected to the partition plate 5. Ventilation holes 17 matching the number of clay refining rooms are opened on the outside of one end of the central tube 7 close to the partition plate 5. Ventilation pipes 18 corresponding to the number of clay refining rooms are installed inside the central tube 7. The air outlet ends of the ventilation pipes 18 are in sealed connection with the ventilation holes 17. The air inlet ends of the ventilation pipes 18 extending outside the barrel 2 are connected to an external air pump, and one-way valves are installed at the air inlet ends of the ventilation pipes 18.

[0023] Combining Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows: I. Initial charging and layered extrusion stage Charging preparation Open the detachable cover plate at the top of the barrel 2, and place the purple sand mud in each mud refining compartment in Chamber 1. The mud refining compartments are separated into multiple groups of independent spaces by the sealing plate 6. Such a design can achieve the treatment of purple sand mud in multiple spaces with small amounts, which helps to improve the mixing uniformity.

[0024] Initial extrusion and transportation After the purple sand mud is placed, start the electric push rod 19. The electric push rod 19 drives the pressing plate 16 to move towards the partition plate 5 to initially extrude the purple sand mud in the mud refining compartment. At this time, under the action of pressure, the purple sand mud enters the central pipe 901 connected thereto through the first material passing groove on the side wall of the barrel 2. It should be noted that although there are multiple central pipes 901 and they are connected to the corresponding mud refining compartments, the pipe diameters in each central pipe 901 can be set differently; For example, the pipe diameters of the 6 central pipes 901 decrease in sequence. Such a design can enable the purple sand mud in different mud refining compartments to generate different flow rates and pressures due to the change in pipe diameter when entering the central pipe 901, forming a shear force, thereby initially breaking the mud mass structure and promoting the mixing of the purple sand mud. At the same time, during this process, the valve plate 11 in the central pipe 901 is in an open state and does not block the central pipe 901 to ensure that the purple sand mud can smoothly enter the pipeline system.

[0025] II. Alternating cycle and dynamic mixing stage Driving of the annular rotating plate 4 and transfer of the mud material After the purple sand mud in the mud refining compartment in Chamber 1 enters the central pipe 901, the servo motor drives the rotating arm 14 to rotate. The number of driving grooves 13 is twice the number of central pipes 901. When the rotating arm 14 rotates two weeks, by using the mutual cooperation of the driving block 15 and the driving groove 13, the annular rotating plate 4 is driven to rotate. The rotation of the annular rotating plate 4 causes the central pipe 901 filled with purple sand mud to be connected to the next mud refining compartment.

[0026] Air pump assistance and circulating flow At this time, the external air pump is started, and the gas is blown into the mud refining compartment through the ventilation pipeline 18, the ventilation hole 17 and the one-way valve. Under the action of the gas, the electric push rod 19 drives the pressing plate 16 to rise until the height of the pressing plate 16 is higher than the height of the first material passing groove in Chamber 1, and continue to blow the gas, so that the purple sand mud in the central pipe 901 is blown by the high-pressure gas into the mud refining compartment in Chamber 2. Then, the pressing plate 16 in Chamber 2 presses the purple sand mud in the mud refining compartment into the central pipe 901 again under the action of the corresponding electric push rod 19; Afterwards, the external air pump starts again, repeating the above process to blow the gas into the second chamber's clay refining area. Subsequently, the electric push rod 19 drives the pressing plate 16 to descend until the height of the pressing plate 16 is lower than the height of the first material feeding trough in the second chamber, and continues to blow the gas, causing the purple sand clay in the central pipe 901 to be blown by the high-pressure gas into the clay refining area in the first chamber. This process is repeated to continuously push the purple sand clay back and forth between the first chamber and the second chamber, achieving sufficient refinement of the purple sand clay. During this process, the design of multiple clay refining areas enables the purple sand clay to be processed in multiple cycles in different spaces, avoiding the problem of uneven mixing that may occur during single-chamber processing. At the same time, the dynamic pressure change and air flow promotion further refine the clay particles, enhancing the uniformity of the purple sand clay.

[0027] III. Directional Discharging and Final Homogenization Stage Discharging Preparation and Connection When the purple sand clay has been processed back and forth between the first chamber and the second chamber and finally reaches the clay refining area in the second chamber, the servo motor drives the rotating arm 14 to rotate one and a half turns. Utilizing the mutual cooperation between the driving block 15 and the driving groove 13, it drives the annular rotating plate 4 to rotate, causing the clay refining area in the second chamber to be connected to the material guiding pipe 902. The valve plate 11 in the material guiding pipe 902 is opened to prepare for discharging.

[0028] Final Discharging and Homogenization Effect The electric push rod 19 drives the pressing plate 16 to press the purple sand clay in the clay refining area in the second chamber to the outside of the material guiding pipe 902. Then the air pump starts again, and through the ventilation pipeline 18, ventilation holes 17 and one-way valves, the gas is blown into the clay refining area in the second chamber. Subsequently, the electric push rod 19 drives the pressing plate 16 to descend until the height of the pressing plate 16 is lower than the height of the first material feeding trough in the second chamber, and continues to blow the gas, causing the purple sand clay in the material guiding pipe 902 to be blown to the outside of the material guiding pipe 902 by the high-pressure gas. Since the purple sand clay has experienced multiple squeezes, shears and air flow dispersions during the entire circulation process, it has formed a state with uniform structure and delicate texture when finally discharged, achieving the purpose of uniform batching. At the same time, the alternating pushing design of multiple clay refining areas not only improves the refining efficiency, but also reduces the load of a single chamber through segmented processing, extending the service life of the equipment.
