Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide screening, in particular to a titanium dioxide screening device with a self-cleaning function. Background Art

[0002] Titanium dioxide, also known as titanium dioxide, is a key inorganic chemical product in the form of white powder. It has many outstanding properties, including extremely high whiteness, strong hiding power, and good weather resistance and chemical stability.

[0003] A Chinese patent application, CN219519469U, discloses a titanium dioxide screening device that is easy to clean. The device comprises a screen frame and a detachable screen disposed on the screen frame, the screen being detachably connected to the screen frame by a disassembly mechanism. The screen is further provided with a cleaning mechanism for cleaning the screen, the cleaning mechanism being rotatable relative to the screen along a hinge. Advantages include utilizing the detachable and replaceable screen to change the screening particle size of the stacked screen frames, which is convenient to use and saves costs, and enhances screening efficiency. Furthermore, a rotatable cleaning brush is utilized to clean residual titanium dioxide adhering to the screen, which is convenient to use and can effectively clean titanium dioxide adhering to the screen. However, in actual use, the device only uses a brush for cleaning, and the cleaning effect of the brush is relatively limited. For some materials with high viscosity or small particles that are easily accumulated, it is difficult to effectively prevent the screen holes from being clogged by the brush alone. As the screening proceeds, the clogged screen holes will increase, resulting in a gradual decrease in the effective screening area, thereby reducing the working efficiency of the device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Specifically, by starting the motor 3, it drives the rotating rod 4 to rotate stably, thereby driving the rotating sleeve 6 thereon to rotate, and with the help of the positioning rod 7 thereon, further drives the brush plate 8 to rotate, thereby comprehensively and effectively cleaning the screening bucket 10. At the same time, through the elastic potential energy of the first torsion spring 5, the brush plate 8 can always be closely contacted with the screening bucket 10 to ensure a good cleaning effect. At the same time, with the continuous rotation of the rotating rod 4, the synchronous rotation of the reciprocating groove 9 thereon can effectively drive the screening bucket 10 to move up and down through the meshing transmission to realize the hopper operation of the material. In this way, the hopper and the brush can be used to keep the screening bucket 10 unobstructed during the screening process.

[0041] Reference Figure 1 、 Figure 4 and Figure 5 The cleaning mechanism 2 includes a top cover 201, which is connected to the top of the top plate 11. A fan 202 is fixedly connected to the left side of the screening barrel 1. The output end of the fan 202 is connected to a duct 203, which is connected to the top cover 201.

A fan blade 206 is fixedly connected to the top of the hollow cover 205. The hollow cover 205 is rotatably connected to the middle part of the inner wall of the top cover 201.

[0042] Specifically, by starting the fan 202, the airflow generated by it is transported to the top cover 201 through the duct 203 for blowing operation. At this time, the airflow will flow smoothly into the top plate 11 from all sides of the top cover 201, and in this process, the fan blades 206 and the hollow cover 205 thereon are driven to rotate. When the hollow cover 205 rotates, it will compress the second torsion spring 204 while driving the perforated disk 207 to rotate together. When the holes between the perforated disk 207 and the top plate 11 are intertwined with each other, the airflow can be blown into the screening barrel 1 smoothly. When the blowing stops, the elastic potential energy of the second torsion spring 204 can make the perforated disk 207 quickly reset, thereby effectively blowing off the titanium dioxide attached to the screening bucket 10, thereby effectively preventing the device from being blocked and ensuring that the device can operate normally and stably.

[0044] Specifically, the handle 12 and the sheath 13 thereon can facilitate holding and carrying the device, and the balance can be adjusted and fixed by rotating the base plate 16 along the bottom of the fixing block 15. The device can be easily installed and fixed by installing a screw member in the positioning hole 18 on the positioning block 17.

[0045] Reference Figure 1 、 Figure 2 and Figure 4 , a controller 14 is fixedly connected to the middle of the front side of the screening barrel 1, and the controller 14 is electrically connected to the motor 3 and the fan 202 respectively; a movable door 20 is provided at the bottom of the right side of the screening barrel 1, and a hinge 21 is fixedly connected to the outer side of the movable door 20, and the movable door 20 is rotatably connected to the screening barrel 1 through the hinge 21; the front and rear sides of the bottom of the fan 202 are fixedly connected to the bracket 19, and the outer side of the bracket 19 is fixedly connected to the screening barrel 1;

[0046] Specifically, the starting and operating power of the motor 3 and the fan 202 can be controlled respectively by the controller 14, and the movable door 20 can be opened and closed by the hinge 21 to facilitate the removal of the screened material from the bottom of the screening barrel 1, and the bracket 19 can improve the firmness of the fixation between the fan 202 and the bracket 19.

[0047] Working principle: Before using the device, first start the motor 3 to drive the rotating rod 4 to rotate, and then drive the rotating sleeve 6 to rotate, and use the positioning rod 7 to rotate the brush plate 8 to clean the screening bucket 10. At the same time, the elastic potential energy of the first torsion spring 5 makes the brush plate 8 always in contact with the screening bucket 10, thereby maintaining the cleaning effect, and as the rotating rod 4 rotates, the reciprocating groove 9 on it rotates, and the screening bucket 10 is driven up and down by the meshing transmission to bucket the material. The material can be scooped and brushed, and the screening bucket 10 can be kept unobstructed while screening;

[0048] By starting the fan 202 and blowing air into the top cover 201 through the duct 203, the air flow will flow into the top plate 11 from all sides of the top cover 201, and at the same time drive the fan blades 206 and the hollow cover 205 thereon to rotate. When the hollow cover 205 rotates, it will compress the second torsion spring 204 while driving the perforated disc 207 to rotate. When the holes between the perforated disc 207 and the top plate 11 intersect, the air flow can be blown into the screening barrel 1. When the blowing stops, the perforated disc 207 can be reset by relying on the elastic potential energy of the second torsion spring 204, thereby blowing off the titanium dioxide attached to the screening bucket 10 to prevent the device from being blocked.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
