Description

Technical Field

[0001] The present application relates to the field of chemical industry, and in particular to a titanium dioxide pulverizer. Background Art

[0002] Titanium dioxide is an important inorganic chemical pigment, primarily composed of titanium dioxide. It is chemically stable and generally unreactive with most substances. Titanium dioxide is produced via two processes: the sulfuric acid process and the chloride process. It is widely used in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics. The final step in titanium dioxide production is pulverization.

[0003] In the related art, a Chinese patent with publication number CN113058702A discloses a titanium dioxide ball mill, which includes a bottom plate and a crushing device. The crushing device includes a crushing roller, a pad is installed on the floor, and support plates are symmetrically installed on the upper end of the pad. A crushing roller is provided between the two support plates. The crushing roller is rotatably connected to the support plate. A number of crushing balls are provided in the crushing roller. An arc groove is opened through the side wall of the crushing roller, and an arc screen is installed on the lower part of the inner wall of the arc groove by sliding fit.

[0004] Manually pull the curved screen out of the curved trough, then transport the titanium dioxide raw materials to be crushed into the crushing roller through the curved trough, and then drive the crushing roller to rotate, driving the crushing balls to move, so that the crushing balls smash and crush the titanium dioxide raw materials in the crushing roller, thereby crushing the titanium dioxide raw materials.

[0005] A collection box is located below the grinding rollers and rests on a pad. Once the titanium dioxide raw material is ground, the curved grooves align with the collection box, allowing the titanium dioxide to fall through the curved screen into the collection box. The grinding balls, however, clog the gaps in the curved screen. A vibration device is installed on the bottom plate to vibrate the grinding rings, displacing the grinding balls and separating them from the curved screen. This allows the titanium dioxide to pass through the curved screen and fall into the collection box for collection.

[0006] The collection of titanium dioxide powder needs to be achieved by continuously vibrating the crushing roller. However, each time the crushing roller is vibrated, the crushing balls are only briefly separated from the curved screen, so that the amount of titanium dioxide powder that passes through the curved screen and enters the collection box during each vibration is very limited. As a result, the efficiency of titanium dioxide powder falling from the crushing roller into the collection box is low, so it needs to be improved. Summary of the Invention

[0007] In order to improve the problem of low efficiency in collecting crushed titanium dioxide, the present application provides a titanium dioxide crusher.

[0008] The titanium dioxide grinder provided in this application adopts the following technical solution:

[0009] A titanium dioxide pulverizer for pulverizing titanium dioxide, comprising:

[0010] A working frame, on which a support plate is fixed;

[0011] A working cylinder, one end of which is open and fixed to the working frame, so as to allow the working cylinder to switch between a vertical state and a horizontal state, a feeding port is formed through the side wall of the working cylinder, and a counterweight is fixed to one end wall of the working cylinder;

[0012] A bottom plate is located at the opening of the working cylinder, the bottom plate is slidably connected to the working cylinder through a stretching assembly, and the bottom plate can be inserted into the working cylinder to block the opening of the working cylinder;

[0013] A crushing assembly, provided in the working box, for crushing the titanium dioxide in the working cylinder;

[0014] The collecting box has an opening at the top and is placed on the working frame. The collecting box is located below the bottom plate and is used to receive the crushed titanium dioxide.

[0015] By adopting the above technical solution, when working, the end of the working cylinder away from the counterweight is first manually moved in the direction away from the support plate, while the counterweight at the other end of the working cylinder applies downward pressure until the side wall of the working cylinder abuts the support plate. The support plate supports the working cylinder, so that the working cylinder remains horizontal. Titanium dioxide is then introduced into the working cylinder through the feed port, and the crushing assembly is activated to crush the titanium dioxide in the working cylinder. When the titanium dioxide is crushed, the crushing assembly is closed and the working cylinder is rotated to overcome the gravity of the counterweight and separate the working cylinder from the support plate. The working cylinder rotates to a vertical position, at which point the counterweight is located at the top of the working cylinder, pressing the working cylinder downward to maintain its vertical position.

[0016] The bottom plate is then moved away from the mandrel, causing the stretching assembly to move on the mandrel, thereby pulling the bottom plate out of the mandrel. This means the opening of the mandrel is open, leaving the crushed titanium dioxide in the mandrel unsupported. This allows the titanium dioxide to quickly fall out of the mandrel through the opening and down through the gap between the mandrel and the bottom plate into the collection bin for collection. During this process, some titanium dioxide will fall onto the bottom plate, but after a certain amount of titanium dioxide accumulates on the bottom plate, it will still fall from the edge of the bottom plate into the collection bin. This prevents the bottom plate from significantly interfering with the titanium dioxide's entry into the collection bin, resulting in a more efficient collection of the crushed titanium dioxide.

[0017] Optionally, the crushing assembly includes:

[0018] An internal gear is provided at an end of the working cylinder away from the opening of the working cylinder, the internal gear is coaxial with the working cylinder and is fixed on the inner wall of the working cylinder;

[0019] A rotating gear is provided on the inner wall of the working cylinder, the rotating gear is located inside the internal gear and meshes with the internal gear, the rotating gear is rotatably connected to the inner wall of the working cylinder via a rotating rod, and the rotating rod is driven by a motor to drive the rotating gear to rotate about the central axis of the working cylinder;

[0020] A plurality of crushing rods are arranged in the working cylinder, one end of each of the crushing rods is fixed on the rotating gear, and the other end of each of the crushing rods is in contact with the bottom plate.

[0021] By adopting the above technical solution, the motor is started, the rotating rod is driven to drive the rotating gear to move, so that the rotating gear rotates in the internal gear with the central axis of the internal gear as the axis, driving the multiple crushing rods to move with the central axis of the working cylinder as the axis, and stirring and crushing the titanium dioxide in the working cylinder. During the movement of the rotating gear, the rotating gear always sticks to the inner wall of the internal gear and moves along the circumferential trajectory of the internal gear, that is, the outer wall of the rotating gear always meshes with the inner wall of the internal gear, so that the rotating gear also rotates during the movement, and then drives the multiple crushing rods to rotate with the central axis of the rotating gear as the axis. Under the premise of the multiple crushing rods rotating with the central axis of the internal gear as the axis, the multiple crushing rods as a whole rotate with the central axis of the internal gear as the axis, so that the trajectories of the multiple stirring rods will cross and overlap, thereby improving the fineness of the crushed titanium dioxide and making the crushing of the titanium dioxide in the working cylinder more thorough.

[0022] Optionally, a limiting disc is provided on the bottom plate, and the limiting disc can move on the bottom plate. A plurality of insertion holes are opened on the limiting disc, and one end of each crushing rod away from the rotating gear is inserted into the corresponding insertion hole.

[0023] By adopting the above technical solution, when the rotating gear drives several crushing rods to move, the crushing rods drive the limiting disc to move on the bottom plate. The limiting disc restricts the crushing rods, so that the two ends of the crushing rods are restricted, and several crushing rods are brought together, so that the crushing rods are less likely to deflect during the movement, which increases the stability of the crushing rod movement and makes the titanium dioxide in the stirring and crushing working cylinder more stable.

[0024] Optionally, a limiting ring is provided on the inner wall of the working cylinder, the limiting ring is coaxial with the working cylinder, and a side of the limiting ring away from the internal gear abuts against a side of the limiting disc close to the internal gear.

[0025] By adopting the above technical solution, the rotating gear drives the crushing rod to rotate with the central axis of the working cylinder as the axis, so that the crushing rod drives the limiting disc to rotate with the central axis of the working cylinder as the axis, so that a part of the area of ​​the limiting disc is always located below the limiting ring. The limiting ring can limit the limiting disc and confine the limiting disc between the limiting ring and the bottom plate, so that the limiting disc is not easy to tilt or deviate during the movement, thereby increasing the stability of the movement of the limiting disc.

[0026] Optionally, the stretching component includes:

[0027] A cleaning ring is arranged in the working cylinder, the outer wall of the cleaning ring abuts against the inner wall of the working cylinder, a moving block is fixed on the side wall of the cleaning ring, a moving groove is opened on the inner wall of the working cylinder along the length direction of the working cylinder, and the moving block is inserted into the moving groove and can move in the moving groove;

[0028] A blocking plate is provided in the movable groove and is used for blocking the movable groove. An end of the blocking plate close to the internal gear is fixed to the movable block, and an end away from the internal gear is fixed to the bottom plate.

[0029] By adopting the above technical solution, when the titanium dioxide powder is crushed, the working cylinder rotates to a vertical state, and then the bottom plate moves downward, driving the blocking plate to move downward in the moving groove, and the bottom end of the blocking plate extends out of the working cylinder from the bottom of the moving groove. The movement of the blocking plate also drives the moving block to move, thereby driving the cleaning ring to move downward in the vertical direction against the inner wall of the working cylinder, thereby scraping off the titanium dioxide powder attached to the inner wall of the working cylinder and moving toward the bottom plate. When the bottom plate drives the cleaning ring to move to the bottom of the working cylinder, the distance between the bottom plate and the working cylinder is also the farthest, making the gap between the bottom plate and the working cylinder larger, and facilitating the passage of titanium dioxide in the working cylinder.

[0030] At the same time, the cleaning ring also scrapes the entire inner wall of the working cylinder, so that the titanium dioxide discharged from the working cylinder is more thorough, and a more comprehensive collection of titanium dioxide is achieved. For the titanium dioxide accumulated on the bottom plate, since the bottom plate is exposed at this time, the operator can directly clean the titanium dioxide on the surface of the bottom plate, which is not easy to cause waste of titanium dioxide.

[0031] Optionally, a fixing rod is provided at the opening of the working cylinder, the fixing rod is perpendicular to the central axis of the working cylinder, and one end is rotatably connected to the end wall of the working cylinder. The fixing rod can be rotated to one side in the length direction of the working cylinder to limit the base plate inserted in the working cylinder from moving out of the working cylinder.

[0032] By adopting the above technical solution, when the base plate is adapted and inserted into the working cylinder, the bottom end of the crushing rod is inserted into the socket and abuts against the base plate, limiting the distance from the base plate to the top wall of the working cylinder. Then the fixing rod is rotated so that the fixing rod moves to the bottom of the base plate and contacts the bottom wall of the base plate to support the base plate. At this time, the two sides of the base plate are restricted by the crushing rod and the fixing rod, thereby maintaining the state of being inserted into the working cylinder and can no longer move in the vertical direction, that is, the base plate blocks the opening of the working cylinder, so that the working cylinder forms a completely closed cylindrical structure, and then the working cylinder is rotated to a horizontal state, so that the titanium dioxide can be crushed.

[0033] Optionally, the working cylinder is provided with a sliding assembly for driving the limiting ring to move, and the sliding assembly includes:

[0034] A transmission belt, a mounting hole is opened in the working cylinder, the transmission belt is arranged in the mounting hole, the transmission belt includes a driving wheel, a driven wheel and a conveyor belt, the driving wheel and the driven wheel are arranged along the length direction of the working cylinder and are rotatably connected to the inner wall of the mounting hole, the conveyor belt is sleeved on the driving wheel and the driven wheel, the conveyor belt moves to drive the driving wheel and the driven wheel to rotate, and the moving block is fixed to one side of the conveyor belt;

[0035] A sliding gear is provided in the mounting hole and is coaxially fixed on the driving wheel;

[0036] A sliding rack is provided in the mounting hole, the sliding rack is fixedly connected to the side wall of the limiting ring, the sliding rack is engaged with the sliding gear, and the sliding rack can be moved out of the mounting hole.

[0037] By adopting the above technical solution, when it is necessary to collect the crushed titanium dioxide, the fixed rod is manually rotated so that the fixed rod moves out of the bottom of the working cylinder, thereby causing the bottom plate to lose its support. Then, the bottom plate moves downward under the action of gravity, driving the cleaning ring to move, causing the moving block to pull the conveyor belt to move, thereby driving the driving wheel to rotate, causing the sliding gear to rotate coaxially, driving the sliding rack to drive the limiting ring to move out of the working cylinder, so that there is no obstacle on the inner wall of the working cylinder, which is convenient for the movement of the cleaning ring. After the bottom plate drives the conveyor belt to move a certain distance, the driving wheel rotates through the teeth on the rotating gear to transmit the sliding rack to a limited distance, so that the movement distance of the limiting ring is less than the movement distance of the bottom plate. When the bottom plate finally moves to the farthest distance, the limiting ring is suspended between the bottom plate and the working cylinder, that is, there is a gap between the working cylinder and the bottom plate, so that it will not interfere with the discharge of titanium dioxide.

[0038] Optionally, a sliding rod is fixed on the side wall of the limit ring, a sliding hole is opened in the working cylinder, one end of the sliding hole passes through the side wall at the opening of the working cylinder, the sliding rod is inserted in the sliding hole and can move out of the sliding hole, and a sliding block is fixed on the end of the sliding rod away from the limit ring, the sliding block is inserted in the sliding hole, and a limiting block is fixed on the inner wall of the sliding hole. The limiting block is located at the opening of the sliding hole and is used to limit the limiting block from moving out of the sliding hole.

[0039] By adopting the above technical solution, when discharging, the working cylinder is placed vertically, and when the limit ring moves downward, the sliding rod and the sliding block both move in the sliding hole. After the limit ring moves out of the working cylinder, the bottom end of the sliding rod also moves out of the moving hole from the bottom end of the sliding hole. When the sliding block moves to the limit block, the side wall of the limit block abuts against the sliding block, limiting the sliding block from continuing to move downward, thereby limiting the limit ring from continuing to move downward, and because the sliding rack is engaged with the sliding gear, the sliding gear is limited to rotate, thereby making the conveyor belt unable to continue to move, that is, the bottom plate cannot move downward. At this time, the bottom plate has also moved to the extreme position, which has a limiting effect on the bottom plate.

[0040] Optionally, the fixing rod is connected to a brush via a connecting rod, and the brush can contact a side of the bottom plate close to the working cylinder and move on the bottom plate.

[0041] By adopting the above technical solution, when the base plate moves to the farthest distance in the direction of the working cylinder, the fixed rod is manually driven to move to the bottom of the working cylinder, so that the connecting rod drives the brush to move to the base plate and slides on the base plate, thereby pushing and scraping off the titanium dioxide accumulated on the base plate, which is convenient to operate.

[0042] Optionally, a feed hopper is fixed on the side wall of the working cylinder, the feed hopper is connected to the feed port, and the inner diameter of the feed hopper gradually decreases from the end away from the working cylinder to the end close to the working cylinder.

[0043] By adopting the above technical solution, the top opening of the feed hopper is larger, which is convenient for holding more titanium dioxide and not easy to spill. The inclined side wall of the feed hopper plays a guiding role, so that the titanium dioxide entering the feed hopper will enter the feed port along the side wall of the feed hopper and be transported to the working cylinder, making feeding more convenient.

[0044] In summary, this application has at least one of the following beneficial effects:

[0045] 1. Move the bottom plate away from the working cylinder so that the bottom plate is pulled out of the working cylinder. That is, the opening of the working cylinder is in an open state, so that the titanium dioxide powder in the working cylinder loses its support, so that the titanium dioxide powder can quickly fall out of the working cylinder through the opening of the working cylinder and fall downward from the gap between the working cylinder and the bottom plate into the collection box for collection;

[0046] 2. Start the motor and drive the rotating rod to drive the rotating gear to move, so that the rotating gear moves in the internal gear, driving several crushing rods to move with the central axis of the working cylinder as the axis, stirring and crushing the titanium dioxide in the working cylinder. During the movement of the rotating gear, the outer wall of the rotating gear is always engaged with the inner wall of the internal gear, so that the rotating gear rotates, and then drives the several crushing rods to rotate as a whole with the central axis of the internal gear as the axis, so that the trajectories of several stirring rods will cross and overlap, thereby improving the fineness of the crushed titanium dioxide and crushing the titanium dioxide in the working cylinder more thoroughly.

DETAILED DESCRIPTION

[0055] The following is combined with Figure 1-7 This application is described in further detail.

[0056] The embodiment of the present application discloses a titanium dioxide pulverizer. Figure 1 and Figure 2 The titanium dioxide pulverizer includes a work frame 10, to which a working cylinder 20 is rotatably connected. Specifically, the working cylinder 20 rotates about the connection between the working cylinder 20 and the work frame 10, causing the central axis of the working cylinder 20 to deflect, that is, the working cylinder 20 can switch between a vertical state and a horizontal state. The working cylinder 20 is a cylindrical structure with one end open and the other end closed. Four counterweights 26 are provided on the end of the working cylinder 20 away from the opening. The counterweights 26 are fixed to the closed end of the working cylinder 20 and are symmetrically arranged about the central axis of the working cylinder 20. Two support plates 11 are fixed to the work frame 10, and the support plates 11 are arranged vertically.

[0057] Reference Figure 1 and Figure 2 A feed port 21 is formed through the side wall of the mandrel 20. A feed hopper 22 is fixed to the side wall of the mandrel 20. When the mandrel 20 is in a horizontal state, the opening of the feed hopper 22 faces upward. The inner diameter of the feed hopper 22 gradually decreases from the end away from the mandrel 20 to the end close to the mandrel 20, and the feed hopper 22 is connected to the feed port 21.

[0058] During operation, the end of the mandrel 20 away from the counterweight 26 is manually moved away from the support plate 11. The counterweight 26 at the other end of the mandrel 20 applies downward pressure until the sidewall of the mandrel 20 contacts the support plate 11. The support plate 11 supports the mandrel 20, keeping it horizontal. At this point, the opening of the feed hopper 22 faces upward, and titanium dioxide is then introduced into the mandrel through the feed port 21 to load the mandrel 20.

[0059] Reference Figure 3 and Figure 4A bottom plate 120 is provided at the opening of the mandrel 20. The bottom plate 120 is arranged perpendicular to the length direction of the mandrel 20 and is slidably connected to the mandrel 20 through the stretching assembly 40. The bottom plate 120 can be inserted into the mandrel 20 to block the opening of the mandrel 20. A fixing rod 70 is provided at the opening of the mandrel 20. The fixing rod 70 is also arranged perpendicular to the central axis of the mandrel 20, and one end of the fixing rod 70 is rotatably connected to the side wall of the mandrel 20. When the bottom plate 120 is inserted into the mandrel 20, the fixing rod 70 is manually rotated so that the fixing rod 70 rotates to one side in the length direction of the mandrel 20, restricting the bottom plate 120 from moving out of the mandrel 20, so that the bottom plate 120 maintains a state of blocking the opening of the mandrel 20. A crushing assembly 30 for crushing the titanium dioxide in the working cylinder 20 is provided in the working cylinder 20, and a collecting box 110 with a top opening is placed on the working frame 10. The collecting box 110 is located below the working cylinder 20, and the opening of the working cylinder 20 is opposite to the top opening of the collecting box 110.

[0060] During operation, the working cylinder 20 is in a horizontal state, and titanium dioxide is first poured into the feed hopper 22. The top opening of the feed hopper 22 is larger, which is convenient for holding more titanium dioxide and not easy to spill. The inclined side wall of the feed hopper 22 plays a guiding role, so that the titanium dioxide entering the feed hopper 22 will enter the feed port 21 along the side wall of the feed hopper 22 and be transported to the working cylinder 20. Then the crushing component 30 is started to crush the titanium dioxide in the working cylinder 20.

[0061] Reference Figure 2 and Figure 4 When the titanium dioxide is crushed, the crushing assembly 30 is closed, the working cylinder 20 is rotated, the gravity of the counterweight block 26 is overcome, and the working cylinder 20 is separated from the support plate 11 until the working cylinder 20 is rotated to a vertical state. At this time, the counterweight block 26 is located at the top of the working cylinder 20, pressing the working cylinder 20 downward so that the working cylinder 20 maintains a vertical state. At this time, the fixed rod 70 is located below the working cylinder 20. The fixed rod 70 is then rotated so that the fixed rod 70 moves out of the bottom area of ​​the working cylinder 20. The bottom plate 120 is then moved away from the working cylinder 20, so that the stretching assembly 40 moves on the working cylinder 20, thereby pulling the bottom plate 120 out of the working cylinder 20, that is, the opening of the working cylinder 20 is in an open state, so that the crushed titanium dioxide in the working cylinder 20 loses its support, so that the titanium dioxide can quickly fall out of the working cylinder 20 from the opening of the working cylinder 20, and fall down from the gap between the working cylinder 20 and the bottom plate 120 to the collection box 110 for collection. During this process, the working cylinder 20 will swing, but it will not affect the discharge of titanium dioxide in the working cylinder 20.

[0062] During this process, some titanium dioxide will fall onto the bottom plate 120, but after a certain amount of titanium dioxide accumulates on the bottom plate 120, it will still fall from the edge of the bottom plate 120 into the collection box 110, so that the bottom plate 120 will not have much impact on the titanium dioxide entering the collection box 110, thereby making the efficiency of collecting the crushed titanium dioxide higher.

[0063] Reference Figure 4 and Figure 5 The crushing assembly 30 includes an internal gear 31, a rotating gear 32 and a plurality of crushing rods 34. The internal gear 31 is located in the working cylinder 20 and is horizontally arranged on the end wall of the working cylinder 20 away from the opening of the working cylinder 20. The internal gear 31 is coaxial with the working cylinder 20. The internal gear 31 is fixed on the inner wall of the working cylinder 20. The rotating gear 32 is horizontally arranged and located in the internal gear 31. The rotating gear 32 is meshed with the internal gear 31 and can rotate eccentrically in the internal gear 31. A rotating rod 321 is rotatably connected to the center of the rotating gear 32. The end of the rotating rod 321 away from the rotating gear 32 is located on the central axis of the working cylinder 20.

[0064] A motor 33 is fixedly connected to the end wall of the working cylinder 20 by bolts. The output end of the motor 33 is coaxially fixed to the end of the rotating rod 321 away from the rotating gear 32, and is used to drive the rotating rod 321 to rotate. A plurality of crushing rods 34 are placed in the working cylinder 20 and arranged along the length of the working cylinder 20. The ends of the crushing rods 34 away from the opening of the working cylinder 20 are fixed to the rotating gear 32. A limiting disc 50 is placed on the bottom plate 120. The limiting disc 50 is arranged horizontally and can slide against the bottom plate 120. The circumferential side wall of the limiting disc 50 abuts the inner wall of the working cylinder 20. The limiting disc 50 is provided with a plurality of sockets 51. The end of each crushing rod 34 away from the rotating gear 32 is inserted into the corresponding socket 51, thereby driving the limiting disc 50 to move on the bottom plate 120 along the movement trajectory of the rotating gear 32.

[0065] The motor 33 is started, driving the rotating rod 321 to move the rotating gear 32, causing the rotating gear 32 to rotate within the internal gear 31 about the central axis of the internal gear 31, driving the plurality of crushing rods 34 to move about the central axis of the working cylinder 20, stirring and crushing the titanium dioxide in the working cylinder 20. Simultaneously, the limiting disc 50 restricts the crushing rods 34, restricting both ends of the crushing rods 34 and bringing the plurality of crushing rods 34 together, thereby reducing the chance of deflection during movement. To increase the fineness of the crushed titanium dioxide, each crushing rod 34 is affixed with a spiral blade, so that when the crushing rod 34 rotates, it also drives the spiral blade to cut and crush the titanium dioxide in the working cylinder 20.

[0066] Reference Figure 4 and Figure 5During the movement of the rotating gear 32, the rotating gear 32 always sticks to the inner wall of the internal gear 31 and moves along the circumferential trajectory of the internal gear 31, that is, the outer wall of the rotating gear 32 always meshes with the inner wall of the internal gear 31, so that the rotating gear 32 also rotates during the movement, thereby driving the plurality of crushing rods 34 to rotate around the central axis of the rotating gear 32 as the axis. Under the premise that the plurality of crushing rods 34 rotate as a whole, the plurality of crushing rods 34 also rotate around the central axis of the internal gear 31 as the axis, so that the trajectories of the plurality of stirring rods will cross and overlap, thereby improving the fineness of the crushed titanium dioxide powder and crushing the titanium dioxide powder in the working cylinder 20 more thoroughly.

[0067] Reference Figure 4 and Figure 5 In order to increase the stability of the movement of the limiting disc 50, a limiting ring 60 is connected to the working cylinder 20 via a sliding assembly 80. The limiting ring 60 is coaxial with the working cylinder 20, and the side of the limiting ring 60 away from the internal gear 31 abuts against the side of the limiting disc 50 close to the internal gear 31. Because the rotating gear 32 drives the pulverizing rod 34 to rotate about the central axis of the working cylinder 20, the pulverizing rod 34 also drives the limiting disc 50 to rotate about the central axis of the working cylinder 20. As a result, a portion of the limiting disc 50 is always located below the limiting ring 60. The limiting ring 60 can restrict the limiting disc 50, confining it between the limiting ring 60 and the bottom plate 120, making it less likely for the limiting disc 50 to tilt or deviate during movement, thereby increasing the stability of the limiting disc 50's movement.

[0068] Reference Figure 5 and Figure 6 The stretching assembly 40 includes a cleaning ring 41 and a blocking plate 42. The cleaning ring 41 is disposed in the working cylinder 20. The outer wall of the cleaning ring 41 abuts against the inner wall of the working cylinder 20. A movable block 411 is fixed to the side wall of the cleaning ring 41. When the working cylinder 20 is placed vertically, a movable groove 23 is formed on the inner wall of the working cylinder 20 in a vertical direction. The movable block 411 is inserted into the movable groove 23 and can move within the movable groove 23. The blocking plate 42 is vertically inserted into the movable groove 23. The top end of the bottom plate 120 is fixed to the movable block 411, and the bottom end is fixed to the limit ring 60. When the base plate 120 is inserted into the working cylinder 20, when the limiting ring 60 abuts against the limiting disc 50, the sealing plate 42 is completely inserted into the movable groove 23, and the movable block 411 is located at the top of the movable groove 23. At this time, the movable block 411 and the sealing plate 42 cooperate to completely block the movable groove 23, so that the titanium dioxide in the working cylinder 20 will not be blocked in the movable groove 23.

[0069] When the titanium dioxide powder is crushed, the bottom plate 120 is moved downward, driving the blocking plate 42 to move downward in the moving groove 23, and the bottom end of the blocking plate 42 extends out of the working cylinder 20 from the bottom of the moving groove 23. As the blocking plate 42 moves, it also drives the moving block 411 to move, thereby driving the cleaning ring 41 to move downward in the vertical direction against the inner wall of the working cylinder 20, thereby scraping off the titanium dioxide powder attached to the inner wall of the working cylinder 20 and moving it toward the bottom plate 120. When the bottom plate 120 drives the cleaning ring 41 to move to the bottom of the working cylinder 20, the distance between the bottom plate 120 and the working cylinder 20 reaches its maximum, making the distance between the bottom plate 120 and the working cylinder 20 larger, making it easier for the titanium dioxide powder in the working cylinder 20 to be discharged from the working cylinder 20.

[0070] Reference Figure 5 At the same time, the cleaning ring 41 also scrapes the entire inner wall of the working cylinder 20, so that the titanium dioxide discharged from the working cylinder 20 is more thorough, and a more comprehensive collection of the titanium dioxide is achieved. As for the titanium dioxide accumulated on the bottom plate 120, since the bottom plate 120 is exposed at this time, the operator can directly clean the titanium dioxide on the upper surface of the bottom plate 120, which is not easy to cause waste of titanium dioxide.

[0071] Reference Figure 4 and Figure 5 The sliding assembly 80 includes a transmission belt 81, a sliding gear 82 and a sliding rack 83. A mounting hole 24 is provided on the end wall at the bottom of the working cylinder 20. The transmission belt 81 is arranged in the mounting hole 24. The transmission belt 81 includes a driving wheel 811, a driven wheel 812 and a conveyor belt 813. The driving wheel 811 and the driven wheel 812 are arranged in a vertical direction and are both rotatably connected to the inner wall of the mounting hole 24. The driving wheel 811 is located below the driven wheel 812. The conveyor belt 813 is sleeved on the driving wheel 811 and the driven wheel 812. The conveyor belt 813 moves to drive the driving wheel 811 and the driven wheel 812 to rotate.

[0072] Reference Figure 6 and Figure 7 The movable groove 23 is connected to the mounting hole 24, and the movable block 411 is fixed to one side of the conveyor belt 813. The sliding gear 82 is disposed in the mounting hole 24 and coaxially fixed to the driving wheel 811. The sliding rack 83 is vertically disposed in the mounting hole 24. The bottom of the sliding rack 83 is fixedly connected to the side wall of the limiting ring 60. The sliding rack 83 meshes with the sliding gear 82. The bottom end of the sliding rack 83 can be moved out of the mounting hole 24 from the bottom end of the mounting hole 24.

[0073] Reference Figure 5 and Figure 7When it is necessary to collect the crushed titanium dioxide, the fixing rod 70 is manually rotated so that the fixing rod 70 moves out of the bottom of the working cylinder 20, thereby causing the bottom plate 120 to lose its support. Then, the bottom plate 120 moves downward under the action of gravity, driving the cleaning ring 41 to move, so that the moving block 411 pulls the conveyor belt 813 to move, thereby driving the driving wheel 811 to rotate, causing the sliding gear 82 to rotate coaxially, driving the sliding rack 83 to drive the limit ring 60 to move out of the working cylinder 20, so that there is no obstacle on the inner wall of the working cylinder 20, which is convenient for the movement of the cleaning ring 41. After the bottom plate 120 drives the conveyor belt 813 to move a certain distance, the driving wheel 811 rotates through the tooth meshing transmission on the rotating gear 32, and the moving distance of the sliding rack 83 is limited, so that the moving distance of the limit ring 60 is smaller than the moving distance of the bottom plate 120, so that after the bottom plate 120 moves to the farthest distance, the limit ring 60 is suspended between the bottom plate 120 and the working cylinder 20, that is, there is a gap between the working cylinder 20 and the bottom plate 120, so that it will not interfere with the discharge of titanium dioxide.

[0074] After the titanium dioxide is collected, the limit ring 60 is directly lifted up to drive the conveyor belt 813 to move, thereby driving the bottom plate 120 to move upward. The limit ring 60 only needs to move a short distance, and the bottom plate 120 can move a longer distance, which facilitates the resetting of the bottom plate 120 structure for the next titanium dioxide crushing.

[0075] Reference Figure 4 In order to prevent the bottom plate 120 from completely separating from the working cylinder 20, a sliding rod 61 is fixed on the side wall of the limiting ring 60. A sliding hole 25 is opened in the working cylinder 20. One end of the sliding hole 25 passes through the side wall at the opening of the working cylinder 20. The sliding rod 61 is vertically inserted in the sliding hole 25 and can move out of the sliding hole 25. A sliding block 611 is fixed on the end of the sliding rod 61 away from the limiting ring 61. The sliding block 611 is inserted in the sliding hole 25. A limiting block 90 is integrally formed on the inner wall of the sliding hole 25. The limiting block 90 is located at the opening of the sliding hole 25, and the distance between the limiting block 90 and the inner wall of one side of the opposite sliding hole 25 is sufficient for the sliding rod 61 to pass through.

[0076] When the limit ring 60 moves downward, the sliding rod 61 and the sliding block 611 both move in the sliding hole 25. After the limit ring 60 moves out of the working cylinder 20, the bottom end of the sliding rod 61 also moves out of the moving hole from the bottom end of the sliding hole 25. When the sliding block 611 moves to the limit block 90, the side wall of the limit block 90 abuts against the sliding block 611, limiting the sliding block 611 from continuing to move downward, thereby limiting the limit ring 60 from continuing to move downward, so that the sliding rack 83 will not disengage from the sliding gear 82. At the same time, because the sliding rack 83 is engaged with the sliding gear 82, the rotation of the sliding gear 82 is limited, and the conveyor belt 813 cannot continue to move, that is, the bottom plate 120 cannot move downward. At this time, the bottom plate 120 has also moved to the extreme position, which has a limiting effect on the bottom plate 120.

[0077] Reference Figure 3 In order to facilitate the cleaning of the titanium dioxide accumulated on the bottom plate 120, after the working cylinder 20 is placed vertically, a connecting rod 71 is fixed to the bottom wall of the fixing rod 70. The connecting rod 71 is arranged vertically, and the bottom end of the connecting rod 71 is fixedly connected to a brush 711. When the bottom plate 120 moves to the farthest distance from the working cylinder 20, the fixing rod 70 is manually driven to move to the bottom of the working cylinder 20, so that the connecting rod 71 drives the brush 711 to move to the top of the bottom plate 120, so that the brush 711 contacts the top wall of the bottom plate 120 and slides on the bottom plate 120, thereby pushing and scraping off the titanium dioxide accumulated on the bottom plate 120.

[0078] The working principle of the titanium dioxide crusher of the embodiment of the present application is as follows: in the initial state, the working cylinder 20 is placed horizontally on the support plate 11. When working, titanium dioxide is first poured into the feed hopper 22. The top opening of the feed hopper 22 is larger, which is convenient for holding more titanium dioxide and not easy to spill. The inclined side wall of the feed hopper 22 plays a guiding role, so that the titanium dioxide entering the feed hopper 22 will enter the feed port 21 along the side wall of the feed hopper 22 and be transported to the working cylinder 20. Then the crushing assembly 30 is started to crush the titanium dioxide in the working cylinder 20.

[0079] When the titanium dioxide is crushed, the crushing assembly 30 is closed, and then the working cylinder 20 is rotated so that the working cylinder 20 is in a vertical state, and the fixing rod 70 is rotated so that the fixing rod 70 moves out of the bottom area of ​​the working cylinder 20, and then the bottom plate 120 is moved away from the working cylinder 20, so that the stretching assembly 40 moves on the working cylinder 20, so that the bottom plate 120 is pulled out of the working cylinder 20, that is, the opening of the working cylinder 20 is in an open state, so that the crushed titanium dioxide in the working cylinder 20 loses its support, so that the titanium dioxide can quickly fall out of the working cylinder 20 from the opening of the working cylinder 20, and fall down from the gap between the working cylinder 20 and the bottom plate 120 to the collection box 110 for collection.

[0080] During this process, some titanium dioxide will fall onto the bottom plate 120, but after a certain amount of titanium dioxide accumulates on the bottom plate 120, it will still fall from the edge of the bottom plate 120 into the collection box 110, so that the bottom plate 120 will not have much impact on the titanium dioxide entering the collection box 110, thereby making the efficiency of collecting the crushed titanium dioxide higher.

[0081] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
