Abstract
Description
Technical Field
[0001] This application relates to the field of powder processing equipment technology, and in particular to a titanium dioxide grinding device. Background Technology
[0002] Titanium oxide (TiO2) is widely used in waste denitrification catalysts, coatings, ceramics, and other fields, and its particle size distribution directly affects product performance. Existing technologies, such as CN222624639U, adjust fineness by replacing the grinding sleeve, which requires stopping the machine for disassembly and replacement, making the operation cumbersome; they use a single grinding roller structure, resulting in low grinding efficiency and insufficient production capacity; and their integrated design makes troubleshooting difficult. Therefore, this application provides a titanium oxide grinding device to solve the above problems. Utility Model Content
[0003] This application provides a titanium dioxide grinding device that solves the problems mentioned in the background art.
[0004] This application provides a titanium dioxide grinding device, including an upper section, a lower section, and a grinding mechanism.
[0005] The upper part includes a frame 1, each of the four corners of the bottom of the frame 1 is provided with a leg 1, the middle of the frame 1 is provided with an upper cavity, the side wall of the upper cavity is connected to a feed pipe, the top of the upper cavity is embedded with a sealed bearing, and the bottom of the upper cavity is provided with a nesting groove.
[0006] The lower half includes a second mounting frame. Each of the four corners of the bottom of the second mounting frame is equipped with a cylinder and a second support leg fixed to the cylinder. The middle of the second mounting frame is equipped with a lower cavity. The top of the lower cavity is equipped with a nested protruding ring. A conical grinding cavity is welded to the bottom of the lower cavity. The bottom of the grinding cavity is connected to a discharge pipe.
[0007] The grinding mechanism includes a motor, with a connecting shaft connected to the output end of the motor, and a grinding roller and a grinding ball tightly welded to the end of the connecting shaft;
[0008] The nested convex ring is nested in the nested groove to form a detachable grinding jar. The motor is located at the top of the upper cavity, and the connecting shaft extends into the grinding jar through the sealed bearing. The grinding roller and grinding ball are located in the middle of the grinding cavity.
[0009] Furthermore, the motor is specifically a servo motor.
[0010] Furthermore, the cylinder is specifically a multi-stage control cylinder.
[0011] Furthermore, the motor and cylinder are electrically connected to the same controller.
[0012] Furthermore, the second mounting bracket is driven vertically by a cylinder.
[0013] Furthermore, the upper and lower halves can be separated.
[0014] As can be seen from the above technical solutions, this application provides a titanium dioxide grinding device, including an upper section, a lower section, and a grinding mechanism.
[0015] The upper section includes a frame and a frame body for the upper cavity. Each of the four corners of the frame has a leg to support it. The upper cavity in the middle of the frame connects with the lower cavity to form a collection container. During the grinding process of the injected titanium dioxide particles by the grinding rollers and grinding balls, this structure collects the powder that is raised during grinding, allowing it to fall off over time and be discharged through the discharge pipe. This prevents powder leakage, reduces losses, ensures production capacity, and minimizes environmental pollution from this process, thus achieving the goal of environmental protection. The upper cavity sidewall is connected to a feed pipe, which is a channel for injecting titanium oxide particles into the equipment. A sealed bearing is embedded in the top of the upper cavity for the installation of the connecting shaft. While ensuring that the connecting shaft can rotate, the device is sealed to reduce the damage of powder to the motor and other structures. A nesting groove is opened at the bottom of the upper cavity, which is used in conjunction with the nesting convex ring. When the upper half and the lower half are movably connected, it is used to nest and engage with the nesting convex ring of the lower half (the bottom of the nesting groove is equipped with a sealing ring. After the nesting convex ring engages with it, it can prevent dust from damaging the structure).
[0016] The lower section includes a second mounting frame, a frame for the lower cavity, and a cylinder and a support leg fixed to each of the four corners of the bottom of the second mounting frame. The cylinders and kinetic energy output structure output kinetic energy during the connection between the upper and lower sections, pushing the second mounting frame, the lower cavity, and the nested protruding ring on its top to rise vertically, allowing the nested protruding ring to nest with the nested groove, thus connecting the upper and lower sections. During grinding, kinetic energy is output as needed, causing the second mounting frame, the lower cavity, the nested protruding ring on its top, and the grinding cavity to rise or fall together (ensuring the nested protruding ring does not disengage from the nested groove), dynamically adjusting the grinding gap between the grinding cavity and the grinding roller and grinding ball assembly to adjust the grinding fineness, thereby achieving controllable grinding fineness to meet production requirements. During maintenance, kinetic energy is output to cause the second mounting frame, the lower cavity, and the nested protruding ring on its top to fall together, separating the upper and lower sections for easy maintenance of internal components. The second mounting frame has a lower cavity in the middle, which connects with the upper section... The two chambers, combined, form a collection container. During the grinding process of the injected titanium dioxide particles by the grinding rollers and grinding balls, this structure is used to collect the powder that is raised during grinding, allowing the powder to fall off over time and be discharged from the discharge pipe. This avoids the leakage of raised powder, reduces losses, ensures production capacity, and reduces the environmental pollution caused by this process, thus achieving the purpose of environmental protection. The top of the lower chamber is provided with a nested protruding ring, which is used in conjunction with the nested groove. When the upper and lower halves are movably connected, it is used to nest with the nested groove of the upper half. The bottom of the lower chamber is welded with a conical grinding chamber, which is the container for grinding the injected titanium dioxide particles. During the grinding process, the grinding chamber wall supports the titanium dioxide particles, allowing the grinding rollers and grinding balls to rotate at high speed under the drive of the motor. The grinding rollers and grinding balls grind the titanium dioxide particles that have not fallen off between the grinding chamber and the grinding roller and grinding ball assembly, thus grinding the titanium dioxide particles into powder. The bottom of the grinding chamber is connected to a discharge pipe, which is the discharge channel for the ground titanium dioxide powder.
[0017] The grinding mechanism includes a motor and a kinetic energy output structure. During the grinding of titanium dioxide particles, the motor outputs kinetic energy to drive the grinding roller and grinding ball assembly to rotate at high speed, providing kinetic energy support for the grinding operation of the grinding roller and grinding ball assembly. The motor output end is connected to a connecting shaft, which is a connecting structure connecting the motor to the grinding roller and grinding ball assembly. The end of the connecting shaft is connected to the grinding roller and the grinding ball tightly welded to it. The grinding roller, the primary grinding structure, performs the grinding function. During the grinding of titanium dioxide particles, it performs coarse grinding of the titanium dioxide particles, grinding larger titanium dioxide particles into smaller titanium dioxide particles to reduce the load on the grinding balls. The grinding balls, the secondary grinding structure, perform the grinding function. They perform fine grinding of the small titanium dioxide particles after being processed by the grinding roller, grinding the small titanium dioxide particles into powdered titanium dioxide, causing the titanium dioxide powder to fall off and be discharged from the discharge pipe.
[0018] The nested convex ring is nested in the nested groove to form a detachable grinding jar. The motor is located at the top of the upper cavity, and the connecting shaft extends into the grinding jar through the sealed bearing. The grinding roller and grinding ball are located in the middle of the grinding cavity.
[0019] In summary, the beneficial effects of this application are as follows:
[0020] 1. After the nested groove and nested convex ring are nested together, the vertical lifting of the set frame, the lower cavity and the grinding cavity assembly can be adjusted by the cylinder. The grinding gap between the grinding roller and grinding ball assembly and the grinding cavity can be directly and dynamically adjusted to achieve dynamic adjustment of the grinding fineness. It is simple to operate and easy to use.
[0021] 2. A dual grinding method combining grinding rollers and grinding balls is adopted. The grinding rollers first coarsely grind large pieces of material, and then the grinding balls finely grind the material ground by the grinding rollers. This not only has high grinding efficiency, but also reduces grinding time and increases production capacity.
[0022] 3. The grinding jar adopts a detachable upper and lower section structure design. The upper and lower sections are connected by nested grooves and nested convex rings. When connecting, simply operate the cylinder to drive the assembly of the setting frame, the lower cavity and the grinding chamber to rise vertically, so that the nested convex ring is nested in the nested groove. When disassembling, simply operate the cylinder to drive the assembly of the setting frame, the lower cavity and the grinding chamber to fall vertically, so that the nested convex ring is separated from the nested groove and flows out of the maintenance gap. The process is quick and convenient for troubleshooting. Attached Figure Description

Detailed Implementation
[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0032] From the above technical solutions, it can be seen that:
[0033] Example 1:
[0034] See Figures 1-5 .
[0035] A titanium dioxide grinding device includes an upper section, a lower section, and a grinding mechanism.
[0036] The upper section includes a frame 1 and a frame body with an upper cavity 3. Each of the four corners of the bottom of the frame 1 has a leg 2 to support it. The upper cavity 3 is located in the middle of the frame 1 and connects with the lower cavity 14 to form a collection container. During the grinding process of the injected titanium dioxide particles by the grinding rollers 9 and grinding balls 10, this structure collects the powder that is raised during grinding, allowing it to fall off over time and be discharged through the discharge pipe 16. This prevents powder leakage, reduces losses, ensures production capacity, and minimizes environmental pollution from this process, thus achieving the goal of environmental protection. The upper cavity 3 has a feed pipe 4 connected to its side wall, which is a channel for injecting titanium oxide particles into the equipment. The top of the upper cavity 3 is fitted with a sealed bearing 5 for the installation of the connecting shaft 8. While ensuring that the connecting shaft 8 can rotate, the bearing 5 ensures the sealing of the device to reduce the damage of the powder to the motor 7 and other structures. The bottom of the upper cavity 3 has a nesting groove 6, which is used in conjunction with the nesting protrusion 17. When the upper half and the lower half are movably connected, the groove 6 is used to nest with the lower half of the nesting protrusion 17 (the bottom of the nesting groove 6 is provided with a sealing ring. After the nesting protrusion 17 is engaged with it, it can prevent dust from damaging the structure).
[0037] The lower section includes a second mounting frame 11 and a frame body with a lower cavity 14. Each of the four corners of the bottom of the second mounting frame 11 has a cylinder 13 and a support leg 12 fixed to each cylinder 13. The cylinders 11 are kinetic energy output structures. During the connection between the upper and lower sections, kinetic energy is output to push the second mounting frame 11, the lower cavity 14, and the nested protruding ring 17 on its top to rise vertically together, allowing the nested protruding ring 17 to nest and engage with the nested groove 6, thus achieving the connection between the upper and lower sections. During the grinding process, kinetic energy is output as needed to drive the second mounting frame 11, the lower cavity 14, and its top... The nested protruding ring 17 and the grinding chamber 15 rise or fall together (while ensuring that the nested protruding ring 17 does not disengage from the nested groove 6) to dynamically adjust the grinding gap between the grinding chamber 15 and the assembly of the grinding roller 9 and grinding ball 10, thereby adjusting the grinding fineness and achieving controllable grinding fineness to meet production requirements. During maintenance, the output kinetic energy drives the second support frame 11, the lower chamber 14, and the nested protruding ring 17 on its top to fall together, separating the upper and lower halves to facilitate maintenance of internal components. Support legs 2 12 and support cylinder 13 are also included. The lower cavity 14 in the middle of the frame 2 11, combined with the upper cavity 3, forms a collection container. During the grinding process of the injected titanium dioxide particles by the grinding roller 9 and grinding balls 10, this structure is used to collect the powder raised by grinding, allowing the powder to fall off over time and be discharged from the discharge pipe 16, thereby avoiding powder leakage, reducing losses, ensuring production capacity, and reducing the environmental pollution of this process, thus achieving the purpose of environmental protection. The top of the lower cavity 14 is provided with a nested protruding ring 17, which is used in conjunction with the nested groove 6. When the upper and lower halves are movably connected, it is used to connect with the upper half. The nested grooves 6 are nested together. The bottom of the lower cavity 14 is welded with a conical grinding chamber 15, which is a container for grinding the injected titanium oxide particles. During the grinding process, the wall of the grinding chamber 15 supports the titanium oxide particles, allowing the grinding roller 9 and grinding ball 10 to rotate at high speed under the drive of the motor 7. The grinding process grinds the titanium oxide particles that have not fallen off between the grinding chamber 15 and the assembly of the grinding roller 9 and grinding ball 10, so as to grind the titanium oxide particles into powder. The bottom of the grinding chamber 15 is connected to the discharge pipe 16, which is the discharge channel for the ground titanium oxide powder.
[0038] The grinding mechanism includes a motor 7, a kinetic energy output structure, which outputs kinetic energy during the grinding of titanium oxide particles, driving the grinding roller 9 and grinding ball 10 assembly to rotate at high speed, providing kinetic energy support for the grinding operation of the grinding roller 9 and grinding ball 10 assembly. The output end of the motor 7 is connected to a connecting shaft 8, a connecting structure that connects the motor 7 to the grinding roller 9 and grinding ball 10 assembly. The end of the connecting shaft 8 is connected to the grinding roller 9 and the grinding ball 10 tightly welded to it. The grinding roller 9 is the primary grinding structure, which performs the grinding function, coarsely grinding the titanium oxide particles during the grinding process, grinding larger titanium oxide particles into smaller titanium oxide particles to reduce the load on the grinding balls. The grinding ball 10 is the secondary grinding structure, which performs the grinding function, finely grinding the small titanium oxide particles after being processed by the grinding roller 9, grinding the small titanium oxide particles into powdered titanium oxide, causing the titanium oxide powder to fall off and be discharged from the discharge pipe.
[0039] The nested protruding ring 17 is nested in the nested groove 6 to form a detachable grinding jar. The motor 7 is located at the top of the upper cavity 3. The connecting shaft 8 extends into the grinding jar through the sealed bearing 5. The grinding roller 9 and the grinding ball 10 are located in the middle of the grinding cavity 15.
[0040] As a preferred embodiment, motor 7 is specifically a servo motor, which realizes closed-loop control of speed and torque, overcomes the problem of stepper motor step loss, has strong overload resistance, and can withstand a load three times the rated torque, which meets the characteristics of the grinding mechanism such as stable grinding and large load, and ensures the normal operation of the grinding process.
[0041] As a preferred embodiment, cylinder 13 is specifically a multi-stage control cylinder, which is beneficial for achieving precise control of grinding fineness in stages.
[0042] In a preferred embodiment, the motor 7 and the cylinder 13 are electrically connected to the same controller, which plays a control role, controlling the operation and speed of the motor 7 and controlling the graded adjustment of the cylinder 13, so as to achieve precise control of the grinding fineness and the matching of the grinding fineness and the speed of the motor 7.
[0043] In a preferred embodiment, the second frame 11 is driven vertically by the cylinder 13 to provide strong support for adjusting the grinding gap between the grinding roller 9 and the grinding ball 10 assembly and the grinding chamber 15.
[0044] As a preferred embodiment, the upper and lower halves can be separated for easy maintenance.
[0045] Working principle:
[0046] When the upper and lower halves are combined: the control cylinder 13 outputs kinetic energy to push the second mounting frame 11, the lower cavity 14 and the nested protruding ring 17 set on its top to rise vertically together, so that the nested protruding ring 17 and the nested groove 6 are nested together.
[0047] When grinding titanium oxide particles: turn on motor 7 to drive the grinding roller 9 and grinding ball 10 assembly to rotate at high speed. Then, titanium oxide particles are continuously fed into the feed pipe 4 in an orderly manner. The grinding roller 9 and grinding ball 10 assembly, which rotate at high speed with motor 7, perform coarse and fine grinding on the titanium oxide particles in sequence, grinding the titanium oxide particles into powdered titanium oxide. During the grinding process, the cylinder 13 can be controlled to output kinetic energy as needed to drive the set frame 11, lower cavity 14 and the nested protruding ring 7 and grinding cavity 15 set on the top to rise or fall together (without the nested protruding ring 17 disengaging from the nested groove 6) by the corresponding distance, so as to dynamically adjust the grinding gap between the grinding cavity 15 and the grinding roller 9 and grinding ball 10 assembly. At the same time, adjust motor 7 to run at the corresponding speed so that the grinding roller 9 and grinding ball 10 assembly grinds the titanium oxide into powder of the required fineness.
[0048] When overhauling the equipment: control cylinder 13 outputs kinetic energy to drive the second mounting frame 11, lower cavity 14 and the nested protruding ring 17 on its top to descend together, so that the upper half and the lower half are separated, and then the internal components are overhauled.
