Description

Technical Field

[0001] The invention belongs to the field of titanium dioxide processing, in particular to an anti-accumulation type vibration screen structure for titanium dioxide processing. Background Art

[0002] Titanium dioxide is an inorganic compound, and its chemical name is titanium dioxide. Titanium dioxide has good hiding power, glossiness and stability, and is widely used in coatings, plastics, rubber, ink, paper, ceramics and other industries. Among them, the application of titanium dioxide in chemical fiber is mainly reflected in its use as a matting agent. Titanium dioxide for chemical fiber is mainly used as a matting agent, and generally uses anatase type. In the processing of titanium dioxide for chemical fiber, the first step is to extract titanium-containing ore from natural ore, and then separate the useful minerals in the ore through crushing, grinding, beneficiation and other processes; the second step is to convert the sorted ore into titanium dioxide through high-temperature oxidation, sulfuric acid method, chlorination method and other processes; the third step is to refine titanium dioxide through grinding, grading, screening and other processes, in which titanium dioxide is screened by a vibrating motor to drive the screen, and an anti-accumulation structure needs to be set on the screen. The anti-accumulation structure is driven by a reciprocating mechanism to drive the toggle plate to move, and the reciprocating toggle plate will smooth the accumulated titanium dioxide to the left or right to prevent the accumulation of titanium dioxide.

[0003] A patent document with publication number CN117463606A discloses an anti-accumulation vibrating screen for titanium dioxide processing, including a first screening net, a second screening net, a vibration motor, a leveling component and a collection box. After the titanium dioxide is conveyed to the first screening net, the vibration motor drives the first screening net and the second screening net to vibrate to achieve the screening effect; at the same time, the toggle plate in the leveling component will move back and forth to prevent the titanium dioxide from accumulating, and finally it is collected by the collection box.

[0004] In the above scheme, titanium dioxide is transported to the first screening net for screening, and at the same time, a leveling component is used to prevent titanium dioxide from piling up during screening. Before fine treatment, titanium dioxide will be piled up in an open working environment for a period of time. After reaching a certain amount, the titanium dioxide will be uniformly finely treated. In an open environment, the moisture content in the air is relatively high. During the period of placement, titanium dioxide will absorb moisture in the air. When the moisture content of titanium dioxide reaches two percent, it will cause titanium dioxide to agglomerate, and wet titanium dioxide will easily clog the mesh of the first screening net. When the mesh is clogged, it will affect the falling of titanium dioxide, thereby affecting the screening effect of titanium dioxide. For this reason, the present invention provides an anti-pile-up vibrating screen structure for titanium dioxide processing. Summary of the invention

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The anti-accumulation type vibrating screen structure for titanium dioxide processing described in the present invention has a drying mechanism. When the titanium dioxide slides downward along the inclined plate, the heating wire heats the inclined plate. The heat energy on the inclined plate evaporates the water in the titanium dioxide. The agglomerated titanium dioxide is deblocked by drying. After the titanium dioxide falls on the screen, the dry titanium dioxide will not block the mesh of the screen, so it will not affect the falling of the screen, thereby avoiding the accumulation of titanium dioxide on the screen and improving the screening effect of titanium dioxide.

[0021] 2. The anti-accumulation vibrating screen structure for titanium dioxide processing described in the present invention has an upward push mechanism. The first driving component drives the scraper to move back and forth along the inclined plate, and the scraper drives the titanium dioxide to move back and forth on the inclined plate. Only a certain amount of titanium dioxide falls each time, which increases the retention time of titanium dioxide on the inclined plate. The comb tooth component also breaks up the agglomerated titanium dioxide to improve the drying effect of titanium dioxide. Secondly, the falling speed of titanium dioxide is reduced to further avoid the accumulation of titanium dioxide on the screen, thereby improving the screening effect of titanium dioxide.

[0022] 3. The anti-accumulation vibrating screen structure for titanium dioxide processing described in the present invention is equipped with a feeding mechanism and a delay mechanism. When there is no titanium dioxide in the feeding mechanism, the hopper continues to move upward through the first spring. The delay mechanism will increase the contact time between the piston and the contact sensor, so that the titanium dioxide that finally falls from the hopper has enough time to stay on the inclined plate and be dried, thereby avoiding the titanium dioxide that finally falls not being dried and causing the titanium dioxide to clog the screen.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1

[0037] like Figure 1-10As shown, an anti-deposit type vibration screen structure for titanium dioxide processing according to an embodiment of the present invention comprises a base 1 and a vibration motor 7, the vibration motor 7 is fixed to the side of the base 1, an elastic support assembly 9 is arranged at the bottom of the base 1, the elastic support assembly 9 comprises a spring and a base, the base is fixed to the ground, and a flexible connection between the base and the base 1 is achieved through the spring, a screen 6 is fixed to the front side of the base 1, two screens 6 are arranged, a toggle plate 8 is arranged on the upper screen 6, and a toggle plate 8 is arranged on the screen 6, and further comprises:

[0038] A material discharge mechanism 2, the material discharge mechanism 2 comprises a hopper 21, and the hopper 21 is arranged above the base 1;

[0039] The drying mechanism 3 includes an inclined plate 31 fixed on the base 1, a baffle 33 is fixed to the side of the inclined plate 31, a heating wire 32 is arranged in the inclined plate 31, and the hopper 21 is arranged on the baffle 33;

[0040] The pushing mechanism 4 includes a fixed seat 41 fixed on the surface of the baffle 33, a connecting seat 42 is provided on the surface of the fixed seat 41, and the surface of the connecting seat 42 is movably connected to the surface of the baffle 33. A first driving component is provided on the fixed seat 41, and the first driving component is used to drive the connecting seat 42 to move upward. A connecting frame 46 is fixed to the bottom of the connecting seat 42, and a scraper 47 movably connected to the inclined plate 31 is rotatably connected to the connecting frame 46, and a second driving component 48 for driving the scraper 47 to rotate is provided on the connecting frame 46.

[0041] Specifically, after the titanium dioxide to be refined is placed in a humid environment for a period of time, the titanium dioxide absorbs part of the moisture in the air, resulting in increased adhesion and aggregation of the titanium dioxide, causing part of the titanium dioxide to clump. At this time, the titanium dioxide is added to the hopper 21, and the titanium dioxide falls from the bottom of the hopper 21 onto the inclined plate 31 of the drying mechanism 3. The inclined plate 31 is heated by the internal heating wire 32. The heat energy on the surface of the inclined plate 31 dries the titanium dioxide. After the titanium dioxide is dried, the adhesion and aggregation of the titanium dioxide are reduced. When the titanium dioxide falls on the screen 6, the titanium dioxide with reduced adhesion is The titanium dioxide will not easily adhere to the mesh of the screen 6, reducing the possibility of clogging of the screen 6. The first driving component can be a cylinder. When the piston rod of the cylinder is extended and retracted, it drives the connecting seat 42 to move up and down reciprocatingly. The connecting seat 42 drives the connecting frame 46 to move up and down reciprocatingly. The connecting frame 46 drives the scraper 47 to move up and down reciprocatingly. The scraper 47 moves up and down reciprocatingly and drives the titanium dioxide to move up and down on the surface of the inclined plate 31, increasing the time that the titanium dioxide stays on the inclined plate 31, improving the drying effect of the titanium dioxide, and the force of the scraper 47 that moves up and down on the titanium dioxide breaks up the small agglomerated titanium dioxide to avoid The agglomerated titanium dioxide accumulates on the screen 6. After the titanium dioxide is dried as a whole, the second driving component 48 can be a motor. When the output shaft of the motor rotates, the scraper 47 is driven to rotate. After the scraper 47 rotates, the titanium dioxide on the inclined plate 31 loses its obstruction and slides down on the surface of the inclined plate 31. At the same time, as soon as the titanium dioxide falls on the screen 6, the vibration motor 7 is started. With the flexible support of the spring, the vibration motor 7 drives the base 1 to vibrate as a whole, and the base 1 drives the upper and lower layers of the screen 6 to vibrate. The titanium dioxide is screened during the vibration of the upper and lower layers of the screen 6, and when the base 1 and the screen 6 vibrate, the inclined plate 31 is driven to vibrate. The plate 31 vibrates. After the inclined plate 31 vibrates, the titanium dioxide remaining on the upper surface of the inclined plate 31 is vibrated off. The qualified titanium dioxide passes through the screen 6 and falls into the collection frame at the bottom of the base 1. The unqualified titanium dioxide is collected in the collection groove on the side of the screen 6. During the screening of the titanium dioxide, the servo motor of the reciprocating mechanism on the base 1 drives the disc to rotate, and the disc drives the circular shaft to rotate. The circular shaft drives it to reciprocate left and right on the inner wall of the driving bar, and the driving bar drives the connecting rod to move, and the connecting rod drives the toggle plate 8 to reciprocate. The toggle plate 8 spreads the titanium dioxide accumulated on the screen 6 to prevent the titanium dioxide from accumulating on the screen 6.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, a guide rod 22 is fixed on the baffle 33, and a middle plate 24 fixedly connected to the hopper 21 is movably sleeved on the surface of the guide rod 22. A first spring 23 is fixed between the middle plate 24 and the baffle 33, and the first spring 23 is sleeved on the surface of the guide rod 22. A top plate 25 is fixed on the top of the guide rod 22.

[0043] Specifically, the guide rod 22 is vertically arranged, and the guide rod 22 guides the middle plate 24 in the vertical direction, so that the middle plate 24 can move more stably in the vertical direction. After the middle plate 24 moves stably, the hopper 21 fixed on the surface of the middle plate 24 can also move more stably in the vertical direction, avoiding problems such as tilting of the hopper 21 during movement. The first spring 23 supports the hopper 21 through the middle plate 24, and the expansion and contraction amount of the first spring 23 changes with the change of titanium dioxide in the hopper 21.

[0044] like Figure 8 and Fig. 9 As shown, a delay mechanism 5 is provided on the top plate 25, and the delay mechanism 5 includes a cylinder body 51 fixed on the top plate 25, a piston 152 is movably connected in the cylinder body 51, a round rod 53 penetrating the middle plate 24 is fixed to the bottom of the piston 152, a round plate 55 movably connected to the surface of the middle plate 24 is fixed to the bottom of the round rod 53, a ring 54 is fixed to the surface of the round rod 53, an air hole 56 penetrates the surface of the cylinder body 51, and a contact sensor 57 is fixed to the top of the inner wall of the cylinder body 51.

[0045] Specifically, after the titanium dioxide inside the hopper 21 has completely fallen out, the hopper 21 drives the middle plate 24 to just contact the ring 54, the middle plate 24 continues to move upward to drive the ring 54 to move upward, the ring 54 drives the round rod 53 to move upward, the round rod 53 drives the piston 152 to move upward, the piston 152 squeezes the gas in the cylinder 51 outward and discharges the gas, and the gas is discharged outward from the air hole 56. Since the air hole 56 is small and the air flow rate is limited, the air takes a long time to be discharged, and the time used by the piston 152 to contact the contact sensor 57 is long, thereby delaying the start of the second drive component 48.

[0046] like Figure 8 and Fig. 9 As shown, a protective ring 58 is fixed to the top of the inner wall of the cylinder body 51 , and the protective ring 58 is arranged on the outside of the contact sensor 57 .

[0047] Specifically, the bottom plane of the protection ring 58 is two millimeters higher than the bottom plane of the contact sensor 57 . The protection ring 58 is used to prevent the piston 152 from excessively moving upward and damaging the contact sensor 57 , thereby protecting the contact sensor 57 .

[0048] like Figure 4 and Figure 5 As shown, a slide rod 43 passes through the connecting seat 42 , and an end of the slide rod 43 is fixed on the fixing seat 41 .

[0049] Specifically, the slide bar 43 is arranged parallel to the inclined plate 31, and the slide bar 43 guides and supports the connecting seat 42, so that the connecting seat 42 only moves along the direction of the slide bar 43, the movement of the connecting seat 42 is more stable, and the connecting seat 42 will not fall downward.

[0050] like Figure 4 and Figure 5 As shown, a second spring 44 is fixed between the connecting seat 42 and the fixing seat 41 , and the second spring 44 is sleeved on the surface of the sliding rod 43 .

[0051] Specifically, when the connecting seat 42 moves obliquely downward along the sliding rod 43, it not only moves by its own gravity, but the second spring 44 also assists the movement of the connecting seat 42, making the connecting seat 42 move faster and avoiding the connecting seat 42 from getting stuck during movement.

[0052] like Figure 5 As shown, the first driving assembly includes a driving motor 451 fixed on the fixing seat 41 , the output shaft of the driving motor 451 passes through the fixing seat 41 and is fixed with a cam 452 , and the surface of the cam 452 is movably connected to the side of the connecting seat 42 .

[0053] Specifically, the driving motor 451 is connected to an external controller via a wire, and the start and stop and rotation speed of the driving motor 451 are controlled by the controller. When the driving motor 451 drives the raised position of the cam 452 to be squeezed on the surface of the connecting seat 42, the connecting seat 42 moves upward along the sliding rod 43. When the raised position of the cam 452 is away from the connecting seat 42, the connecting seat 42 moves downward along the sliding rod 43.

[0054] like Figure 6 and Figure 7 As shown, the second driving assembly 48 includes an electric push rod 481 fixed on the connecting frame 46. The telescopic end of the electric push rod 481 passes through the connecting frame 46 and is fixed with a rack 482. A shaft gear 483 is meshed below the rack 482. The shaft gear 483 passes through the side of the connecting frame 46 and is fixedly connected to the surface of the scraper 47.

[0055] Specifically, the electric push rod 481 is connected to the external controller through a guide, and the controller controls the electric push rod 481 to extend or retract. When the electric push rod 481 retracts, the electric push rod 481 drives the rack 482 to move obliquely downward along the inner wall of the connecting frame 46, and the rack 482 moves on the surface of the shaft gear 483. The rack 482 will drive the shaft gear 483 to rotate, and the shaft gear 483 will drive the scraper 47 to rotate. At this time, after the scraper 47 is opened, the scraper 47 cannot block the titanium dioxide, and the titanium dioxide slides directly downward on the inclined plate 31; when the electric push rod 481 is extended, the electric push rod 481 drives the rack 482 to move upward, the rack 482 drives the shaft gear 483 to rotate, and the shaft gear 483 drives the scraper 47 to rotate, and the scraper 47 stops when it is vertical to the inclined plate 31.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the rotation range of the scraper 47 is from 0 to 60 degrees, and the scraper 47 increases the falling speed of the titanium dioxide powder after rotating upward.

[0057] Specifically, after the scraper 47 rotates, the distance between the scraper 47 and the inclined plate 31 increases, and the scraper 47 cannot block the titanium dioxide on the inclined plate 31. After the scraper 47 rotates completely, the titanium dioxide on the inclined plate 31 can flow completely downward to avoid the titanium dioxide accumulation on the scraper 47.

[0058] Embodiment 2

[0059] like Figure 4 and Figure 6 As shown, compared with Example 1, another embodiment of the present invention is: a comb tooth assembly 49 is arranged on the inclined plate 31, and the comb tooth assembly 49 includes an upper comb tooth 491 fixed to the bottom of the scraper 47, and the bottom of the upper comb tooth 491 is movably connected to the upper surface of the inclined plate 31, and a lower comb tooth 492 is fixed on the inclined plate 31, and the top of the lower comb tooth 492 is movably connected to the bottom of the scraper 47, and the upper comb tooth 491 and the lower comb tooth 492 are staggered in the upper and lower directions.

[0060] Specifically, when the scraper 47 moves back and forth up and down, the scraper 47 drives the upper comb teeth 491 to move, and the upper comb teeth 491 slide between two adjacent lower comb teeth 492. The agglomerated titanium dioxide powder between the two adjacent lower comb teeth 492 will be squeezed and crushed by the extrusion force between the lower comb teeth 492 and the upper comb teeth 491. The contact area between the agglomerated titanium dioxide powder and the inclined plate 31 is small, which avoids incomplete drying of the agglomerated titanium dioxide powder on the inclined plate 31. After the agglomerated titanium dioxide powder is crushed, not only the drying effect of the titanium dioxide powder is increased, but also the agglomerated titanium dioxide powder is prevented from accumulating on the screen 6.

[0061] Working principle: After the production of titanium dioxide is completed, it is necessary to refine the titanium dioxide to improve the product quality of titanium dioxide. During the refinement, the titanium dioxide needs to be screened. During the screening process, the electric control valve at the bottom of the hopper 21 is closed first, and the titanium dioxide is transported into the hopper 21 through a screw conveyor. After the transportation is completed, the hopper 21 compresses the first spring 23 downward by the total weight of the titanium dioxide, and then the heating wire 32 is started. When the heating wire 32 heats the temperature of the inclined plate 31 to about 35 degrees Celsius, the control valve at the bottom of the hopper 21 is opened, and the titanium dioxide will fall on the surface of the inclined plate 31. The titanium dioxide slides along the direction of the inclined plate 31, and the temperature on the inclined plate 31 evaporates the water in the titanium dioxide;

[0062] Before the titanium dioxide falls on the inclined plate 31, the push-up mechanism 4 needs to be started. At this time, the driving motor 451 on the fixed seat 41 will drive the cam 452 to rotate slowly. When the protruding position of the cam 452 squeezes the connecting seat 42, the connecting seat 42 moves along the slide bar 43, and the connecting seat 42 squeezes the second spring 44 to compress the second spring 44. At this time, the connecting seat 42 drives the connecting frame 46 to move, and the connecting frame 46 drives the scraper 47 to move obliquely upward along the direction of the slide bar 43 through the shaft gear 483. When the protruding position of the cam 452 is not After squeezing the connection seat 42, the connection seat 42 will move obliquely downward along the direction of the slide rod 43 by its own gravity and the rebound force of the second spring 44. At this time, the scraper 47 moves back and forth up and down. When the titanium dioxide powder slides obliquely downward along the inclined plate 31, the titanium dioxide powder will contact the first scraper 47. The scraper 47 moving upward will push the titanium dioxide powder obliquely upward along the inclined plate 31. When the scraper 47 moves downward, the titanium dioxide powder moves downward together with it. The titanium dioxide powder will move back and forth on the inclined plate 31 following the scraper 47. , thereby increasing the time that titanium dioxide stays on the inclined plate 31 and improving the drying effect of titanium dioxide during drying. When the first layer of scraper 47 is filled with titanium dioxide, the titanium dioxide will overflow the scraper 47 and accumulate on the second layer of scraper 47. The titanium dioxide moves up and down with the second layer of scraper 47, and then the titanium dioxide will pass through the third, fourth and other subsequent scrapers 47 in sequence until the titanium dioxide passes over the last layer of scraper 47 and falls on the screen 6. In the reciprocating motion, the titanium dioxide will roll on the surface of the scraper 47 and pass through the titanium dioxide. The titanium dioxide tumbles with each other, and the agglomerated titanium dioxide collides with each other, and the agglomerated titanium dioxide is broken, thereby increasing the contact area between the titanium dioxide and the inclined plate 31, making the titanium dioxide dry more thoroughly, and further preventing the titanium dioxide from clogging the mesh of the screen 6. Secondly, during the reciprocating motion of the scraper 47, the scraper 47 also drives the upper comb teeth 491 to move up and down between the lower comb teeth 492. At this time, the extrusion force between the upper comb teeth 491 and the lower comb teeth 492 crushes the agglomerated titanium dioxide between the two, further reducing the agglomerated titanium dioxide.

[0063] As the drying component runs, in the unloading mechanism 2, the titanium dioxide inside the hopper 21 will decrease, the overall mass of the hopper 21 and the titanium dioxide will decrease, the first spring 23 will rebound upward, the first spring 23 drives the middle plate 24 to move upward, the middle plate 24 will move vertically upward under the guidance of the guide rod 22, the middle plate 24 drives the hopper 21 to move upward, when the titanium dioxide inside the hopper 21 is completely discharged, at this time, the first spring 23 drives the middle plate 24 to move upward to a position that just touches the ring 54, the middle plate 24 continues to move upward, the middle plate 24 will drive the ring 54 to move upward, the ring 54 drives the round rod 53 to move upward, the round rod 53 drives the piston 152 to move upward, the piston 152 is fixed at the bottom of the top plate 25 at this time, the piston 152 moves upward to compress the air inside the cylinder 51 and discharge it outward from the air hole 56, because the air hole 56 is small, the flow rate of the air discharged outward is limited, and the air inside the cylinder 51 is slowly discharged outward, The piston 152 moves upward at a slow speed. When the piston 152 contacts the contact sensor 57, the contact sensor 57 will send a signal to start the electric push rod 481. The electric push rod 481 drives the rack 482 to move. The rack 482 moves on the surface of the shaft gear 483. Through the meshing between the rack 482 and the shaft gear 483, the rack 482 will drive the shaft gear 483 to rotate, and the shaft gear 483 drives the scraper 47 to flip. At this time, the titanium dioxide blocked by the scraper 47 will all lose its obstruction, and the titanium dioxide will all flow downward from the inclined plate 31, so as to avoid the accumulation of titanium dioxide on the scraper 47 when the machine stops operating. The period from the completion of the dropping of all titanium dioxide in the hopper 21 to the triggering of the contact sensor 57 by the piston 152 is the time period for the drying of the titanium dioxide that finally falls on the inclined plate 31. The delay mechanism 5 is used to extend the drying time of the titanium dioxide that finally falls on the inclined plate 31, so as to avoid the titanium dioxide that finally falls not being dried fully.

[0064] During the drying period, the collecting frame is placed inside the base 1. When the first part of the titanium dioxide powder falls on the screen 6, the subsequent titanium dioxide powder will continue to fall on the screen 6. At this time, the servo motor is started, and the servo motor drives the disc to rotate. The disc drives the circular shaft on the surface to make a circular motion. The circular shaft will move up and down on the inner wall of the driving strip, and the circular motion of the circular shaft will drive the driving strip to reciprocate left and right. The driving strip will drive the connecting rod to reciprocate left and right, and the connecting rod will drive the toggle plate 8 to reciprocate. The toggle plate 8 will evenly spread the titanium dioxide powder accumulated on the upper screen 6 to the left and right to prevent the accumulation of titanium dioxide powder. At the same time, the vibration motor 7 drives the base 1 to vibrate, and the base 1 drives the two layers of screens 6 to vibrate. The titanium dioxide powder on the upper screen 6 is sieved and falls on the lower screen 6. After passing through the lower screen 6, the titanium dioxide powder falls into the collecting frame, and the base 1 is connected to the base by the flexibility of the spring to vibrate. Qualified titanium dioxide powder will fall into the collecting frame, and unqualified titanium dioxide powder will be collected in the collecting tank, and finally cleaned up uniformly;

[0065] When the overall sorting is completed, the control valve at the bottom of the hopper 21 is closed again, and titanium dioxide is added into the hopper 21 again. With the addition of titanium dioxide, the hopper 21 will move downward again, and the hopper 21 will drive the middle plate 24 to move downward. The first spring 23 will be compressed again, and the middle plate 24 will continue to move downward. The middle plate 24 will contact the circular plate 55, and the middle plate 24 will drive the circular plate 55 to move downward. The circular plate 55 will drive the round rod 53 to move downward, and the round rod 53 will drive the piston 152 to move slowly downward. At this time, air enters the cylinder body 51 through the air hole 56 until the feeding inside the hopper 21 is completed, and then a new round of screening can be carried out.
