Description

Technical Field

[0001] The invention relates to the technical field of suspended porcelain insulator processing, in particular to a ceramic slurry automatic permanent magnetic iron removal device and method. Background Art

[0002] Suspension porcelain insulators are a special type of insulation control that can play an important role in ground insulation and conductor support in high-voltage overhead transmission lines. Due to the influence of the raw materials used and the processing process, a certain amount of iron impurities are often mixed into the ceramic slurry of porcelain insulators. The presence of iron impurities will seriously affect the electrical performance and mechanical strength of the insulator, and even cause insulation failure and become a zero-value insulator, which will cause serious power accidents. At present, magnetic rods are usually used to remove iron impurities in the ceramic slurry of suspension porcelain insulators. This method often has the following problems during the production process:

[0003] As the amount of iron impurities adsorbed on the magnet bar increases, its surface will gradually be covered, resulting in a weakening of the magnetic field strength and a significant decrease in iron removal efficiency. Therefore, manual cleaning is usually required on a regular basis, which not only increases the difficulty of operation and labor costs, but also interrupts the continuity of the production process and affects work efficiency.

[0004] When the magnet rod is manually removed, the mud is easily taken out, resulting in a waste of raw materials;

[0005] Due to the dense distribution of magnet bars, manual cleaning is difficult, which will result in the iron impurities on some surfaces of the magnet bars not being completely removed, affecting the secondary iron removal efficiency;

[0006] Since the installation positions of the magnet bars are relatively fixed, some magnet bars may not be able to play the iron removal effect, while some magnet bars have too many iron impurities adsorbed on their surfaces, affecting the iron removal effect.

[0007] To this end, we propose an automatic permanent magnetic iron removal device and method for ceramic slurry. Summary of the invention

[0008] The purpose of the present invention is to provide an automatic permanent magnetic iron removal device and method for ceramic slurry, so as to solve the problem that the current way of removing iron impurities in ceramic slurry proposed in the above background technology increases with the increase of iron impurities adsorbed on the magnet rod, resulting in weakening of magnetic field strength and significant decrease in iron removal efficiency, requiring manual regular cleaning, which not only increases the difficulty of operation and labor costs, but also interrupts the continuity of the production process and affects work efficiency.

[0009] To achieve the above object, the present invention provides the following technical solutions:

[0010] An automatic permanent magnetic iron removal device for ceramic slurry comprises at least one processing pool with a feed port and a discharge port respectively arranged on both sides, an assembly seat is arranged in the processing pool, a mounting frame is arranged in the assembly seat, the bottom end of the mounting frame extends to the bottom of the inner cavity of the processing pool through a movable opening opened at the bottom of the assembly seat, a conveyor belt mechanism is arranged in the mounting frame, a roller shaft portion located in the assembly seat of the conveyor belt mechanism is connected to the output end of the rotating device through a gear set, a plurality of groups of magnetic blocks for removing iron impurities in the slurry are embedded in the outer wall of the conveyor belt body of the conveyor belt mechanism, filter holes for filtering the slurry are evenly opened on the outer wall of the conveyor belt body between two adjacent groups of magnetic blocks, and an automatic cleaning mechanism for cleaning the conveyor belt body is arranged on the bottom wall of the assembly seat;

[0011] It also includes a reciprocating mechanism for driving the assembly seat to reciprocate in the treatment tank when the conveyor belt mechanism is transporting, and a guide mechanism arranged in the mounting frame for limiting the slurry from entering and exiting the filter hole in one direction.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The present invention drives the conveyor belt mechanism through a rotating device, and the conveyor belt body in the conveyor belt mechanism is transported. At the same time, the reciprocating mechanism drives the assembly seat to drive the conveyor belt mechanism to move back and forth in the treatment pool. When the conveyor belt mechanism moves and transports, the magnetic block on its outer wall circulates into the ceramic slurry to absorb the iron impurities in the ceramic slurry. Then, during the conveyor belt body transportation process, the automatic cleaning mechanism cleans the iron impurities absorbed on the magnetic block into the assembly seat, without manual regular cleaning, reducing the difficulty of operation and labor costs, improving the iron removal effect and the working efficiency of iron removal, and at the same time does not affect the secondary iron removal efficiency of the magnetic block;

[0014] When the rotating device drives the conveyor belt body to convey, the induced draft fan is operated through the transmission shaft and the speed change gear set. The induced draft fan blows air through the second air outlet end to make the slurry on the surface of the magnetic block fall back into the processing pool from top to bottom before the magnetic block is automatically cleaned by the mechanism, thereby avoiding slurry waste.

[0015] The present invention also provides filter holes on the conveyor body. When the conveyor mechanism moves and conveys, the impurity particles in the ceramic slurry are filtered through the filter holes under the action of the guide mechanism, and the impurity particles can be cleaned by the automatic cleaning mechanism when the conveyor body is conveying, thereby improving the quality and uniformity of the slurry and ensuring the quality and performance of the final product. At the same time, the induced draft fan of the present invention is also provided with a first air outlet end, and air is blown to the conveyor body through the first air outlet end, so that the impurity particles blocked in the filter holes are better separated from the filter holes, thereby ensuring that the filter holes filter the slurry stably;

[0016] When the conveyor belt body is conveying, the present invention also rotates the stirring rod and drives the rotating rod to rotate through the transmission shaft, the bevel gear set and the transmission member. The rotation of the stirring rod can stir the slurry, effectively improve the iron removal quality, prevent the deposition of iron impurities, and promote the uniformity of the slurry. The driving rotating rod can drive the cleaning member to rub the conveyor belt body, and preliminarily clean the conveyor belt body before the scraper cleans it.

[0017] The reciprocating mechanism of the present invention enables the assembly seat to reciprocate left and right in the processing pool when the conveyor belt body is transporting, thereby improving the iron and impurity removal range and efficiency of the ceramic slurry, and also improving the stirring range of the ceramic slurry, so that the ceramic slurry has higher uniformity, improving the iron and impurity removal quality as well as the quality and performance of the final product.

[0027] An assembly seat 4 is provided at the top of the processing pool 1, and a mounting frame 5 is provided in the assembly seat 4. The mounting frame 5 is two plates arranged opposite to each other. The bottom end of the mounting frame 5 extends to the bottom of the inner cavity of the processing pool 1 through a movable opening opened at the bottom of the assembly seat 4. A conveyor belt mechanism 6 is provided in the mounting frame 5. The conveying direction of the conveyor belt mechanism 6 is counterclockwise. The conveyor belt mechanism 6 belongs to a conventional structure in the field, including rollers respectively rotating at the upper and lower ends of the mounting frame 5 and a conveyor belt body transmitting at the outer walls of the upper and lower rollers. A roller shaft portion of the conveyor belt mechanism 6 located in the assembly seat 4 is connected to the output end of the rotating device 9 through a gear set 10. The gear set 10 is two sets of meshing gears. The rotating device 9 is arranged in the assembly seat 4. The rotating device 9 is, for example, a motor and a reducer. The rotating device 9 specifically rotates clockwise, and the gear set 10 causes the conveyor belt body in the conveyor belt mechanism 6 to transmit counterclockwise.

[0028] The outer wall of the conveyor body of the conveyor mechanism 6 is embedded with a plurality of groups of magnetic blocks 7 for removing iron impurities in the slurry, and is used to absorb the iron impurities in the ceramic slurry;

[0029] The outer wall of the conveyor belt body between two adjacent groups of magnetic blocks 7 is evenly provided with filter holes 8 for filtering the slurry, and the filter holes 8 play the role of blocking and intercepting the impurity particles in the aggregated ceramic slurry. The bottom outer wall of the conveyor belt body or the bottom of the mounting frame can be fitted with or gap-connected with the bottom outer wall of the treatment tank 1. The bottom wall of the assembly seat 4 is provided with an automatic cleaning mechanism for cleaning the conveyor belt body, specifically cleaning the iron impurities on the conveyor belt body and the impurity particles at the filter holes 8;

[0030] It also includes a reciprocating mechanism for driving the assembly seat 4 to reciprocate in the treatment tank 1 when the conveyor belt mechanism 6 is conveying, and a guide mechanism arranged in the mounting frame 5 for limiting the slurry from entering and exiting the filter hole 8 in one direction.

[0031] See also Figure 3-Figure 6 Preferably, the automatic cleaning mechanism of this embodiment includes:

[0032] The guide rail assembly 13 is obliquely inserted into the bottom wall of the assembly seat 4, and a through hole adapted to the guide rail assembly 13 is opened on the bottom wall of the assembly seat 4. Figure 3-Figure 4 It can be seen that the guide rail group 13 is specifically located on the left side of the conveyor belt mechanism 6. The guide rail group 13 is composed of a guide rail and a slider sliding in the slide groove of the guide rail. The slider of the guide rail group 13 is obliquely provided with a scraper 11. The guide rail group 13 is provided with an elastic member 12 for driving the scraper 11 to contact the outer wall of the conveyor belt body. The elastic member 12 is, for example, a spring, one end of which is connected to the slider and the other end is connected to the inner wall of one side of the slide groove. Through this arrangement, the scraper 11 can be automatically driven to move when the scraper 11 and the conveyor belt body are worn by friction, so as to prevent a gap from being generated between the two and affecting the cleaning quality;

[0033] The exhaust pipe 32 has one end connected to the inner cavity of the assembly seat 4 and corresponding to the scraper 11, and the other end connected to an external extraction device, such as an iron impurity suction machine or an industrial vacuum cleaner, etc., through which the iron impurities and impurity particles scraped into the assembly seat 4 can be extracted to the outside for collection or treatment; and

[0034] The vibration mechanism is arranged on the bottom wall of the assembly seat 4, and is used to drive the scraper 11 to vibrate so that the iron impurities scraped by the scraper 11 can be better separated from the scraper 11, and because the scraper 11 is inclined, it also guides the scraped iron impurities and impurity particles, so that the scraped iron impurities and impurity particles flow along the scraper 11 to the discharge pipe 32, which can effectively prevent the iron impurities from being adsorbed again.

[0035] Preferably, the vibration mechanism of this embodiment includes:

[0036] The friction wheel 16 is rotatably mounted on the bottom wall of the assembly seat 4 through the mounting seat and the rotating shaft and contacts the conveyor belt body. The conveyor belt body is driven to rotate. When the conveyor belt body is conveyed, it rubs against the friction wheel 16, causing the friction wheel 16 to rotate; and,

[0037] The eccentric wheel 17 is eccentrically sleeved on the shaft of the friction wheel 16. When the friction wheel 16 rotates, the eccentric wheel 17 also rotates. The bottom of the eccentric wheel 17 abuts against an L-shaped movable rod 15. The vertical section of the movable rod 15 movably passes through the bottom wall of the assembly seat 4 and extends to the bottom of the scraper 11. The end of the vertical section of the movable rod 15 is embedded with a knocking ball 14 in contact with the scraper 11. The outer wall of the movable rod 15 is sleeved with a spring for driving it to contact with the eccentric wheel 17. One end of the spring is connected to the outer wall of the movable rod 15, and the other end is connected to the outer wall of the assembly seat 4. When the eccentric wheel 17 rotates, the movable rod 15 is moved downward, thereby making the knocking ball 14 away from the scraper 11. Then, as the eccentric wheel 17 rotates, the movable rod 15 is reset upward under the action of the spring to knock the scraper 11 through the knocking ball 14, driving the scraper 11 to vibrate.

[0038] Preferably, a transmission shaft 18 is inserted into the mounting frame 5 of the present embodiment, and a bearing is provided at the connection between the transmission shaft 18 and the mounting frame 5. One end of the transmission shaft 18 is transmission-connected to a roller shaft located in the assembly seat 4, and a sprocket transmission group can be used for transmission connection. The other end extends into the mounting frame 5 and is transmission-connected to the top of a stirring rod 20 through a bevel gear group 19. The bevel gear group 19 is a plurality of groups of bevel gears meshing with each other (three groups of bevel gears meshing with each other in the present embodiment), one group of bevel gears is sleeved on the top of the outer wall of a stirring rod 20, and another group of bevel gears is sleeved on one end of the outer wall of the transmission shaft 18. The stirring rod 20 is provided with a plurality of groups, all of which are vertically inserted on the support block, and the support block is fixed in the mounting frame 5. The plurality of groups of stirring rods 20 are transmission-connected, and a gear group (two groups of gears meshing with each other) or a sprocket transmission group (sprocket and chain) can be used.

[0039] When the conveyor belt body is driven, the transmission shaft 18 is driven at the same time. The transmission shaft 18 drives a stirring rod 20 through a bevel gear set 19, and then several groups of stirring rods 20 rotate synchronously to stir the slurry, effectively improving the iron removal quality, preventing the deposition of iron impurities, and promoting the uniformity of the slurry.

[0040] Preferably, the bevel gear set 19 of the present embodiment is also transmission-connected to the speed change gear set 22, and the speed change gear set 22 is connected to the impeller shaft of the induced draft fan 21. The speed change gear set 22 includes a protrusion fixed in the mounting frame 5, and two sets of shafts rotatably arranged on the protrusion. Another bevel gear in the bevel gear set 19 is sleeved on one shaft, and a large gear is also sleeved on the shaft, and a small gear meshing with the large gear is sleeved on the other shaft. The number of teeth of the large gear is 2-4 times the number of teeth of the small gear, and the other shaft is connected to the impeller shaft of the induced draft fan 21. In this way, the rotational force of the transmission shaft 18 can be accelerated and then transmitted to the impeller of the induced draft fan 21, so that the induced draft fan 21 can work efficiently. The induced draft fan 21 is arranged in the mounting frame 5 and its first air outlet end 36 is located above the scraper 11. The first air outlet end 36 is In the horizontal air outlet direction, the second air outlet end 37 of the induced draft fan 21 is arranged on the inner wall of the top of the assembly seat 4 and its air outlet direction is toward the conveyor belt body, which is used to blow air to the surface of the conveyor belt body so that the slurry on the surface falls back into the processing tank 1 through the movable port. The second air outlet end 37 is in the vertical air outlet direction. The air inlet end of the induced draft fan 21 passes through the top of the assembly seat 4 through the air inlet pipe 31, and is discharged from the air outlet end after drawing in the outside air. The air outlet end blows toward the conveyor belt body. When the filter hole 8 on the conveyor belt body corresponds to the first air outlet end 36, the gas causes the impurity particles blocked in the filter hole 8 to separate from the filter hole 8. When the conveyor belt body is transported, the gas blown downward by the second air outlet end 37 can make the slurry driven upward by the conveyor belt body and the magnetic block fall back into the processing tank 1 from the movable port, thereby avoiding slurry waste.

[0041] It should be noted that valves for adjusting the air volume can be set at the first air outlet end 36 and the second air outlet end 37. The air volume of the first air outlet end 36 is greater than that of the second air outlet end 37, so that the iron impurities adsorbed by the magnetic block 7 are not easily blown away from the magnetic block 7 when the second air outlet end 37 blows air.

[0042] Preferably, in this embodiment, a plurality of groups of driving rotating rods 28 are rotatably provided on the inner wall of the assembly seat 4 and located above the induced draft fan 21. The plurality of groups of driving rotating rods 28 are equidistantly arranged along the width direction of the assembly seat 4. The plurality of driving rotating rods 28 are transmission-connected with each other, and a sprocket transmission group transmission connection can be adopted. One of the driving rotating rods 28 is transmission-connected with the output end of the rotating device 9 through a transmission member 29. The transmission member 29 can be, for example, a worm gear provided at the output end of the rotating device 9 and a worm gear provided on the outer wall of one of the driving rotating rods 28. A cleaning member 30 for contacting the outer wall of the conveyor belt body is provided on the side of the driving rotating rod 28 facing the conveyor belt body. The cleaning member 30 can be, for example, a brush plate.

[0043] Preferably, the reciprocating mechanism of this embodiment includes:

[0044] The toothless gear 23 is arranged on the drum shaft in the assembly seat 4. A connecting gear is meshed on one side of the toothless gear 23. A capstan 24 is sleeved on the shaft of the connecting gear. A pull rope 25 is wound around the outer wall of the capstan 24. The other end of the pull rope 25 is connected to the inner wall of the treatment tank 1 away from the assembly seat 4. The toothless gear 23 drives the connecting gear intermittently during the transmission of the conveyor belt mechanism 6, so that the capstan 24 reels the pull rope 25 to drive the assembly seat 4 to move from one side of the inner cavity of the treatment tank 1 to the other side of the inner cavity of the treatment tank 1. Figure 1 As shown, the assembly seat 4 is initially located on the right side of the treatment tank 1, and moves to the left side under the action of the pull rope 25;

[0045] The second elastic member 26 is connected to the assembly seat 4 and the inner wall of one side of the processing tank 1, and is used to drive the assembly seat 4 to reset when the toothless gear 23 and the connecting gear are separated. The second elastic member 26 is, for example, a spring. Through this arrangement, it is convenient for the assembly seat 4 to drive the conveyor belt mechanism 6 to move back and forth in the processing tank 1, thereby improving the range and efficiency of iron and impurity removal of the ceramic slurry, and also plays a role in stirring the ceramic slurry, thereby improving the quality of iron and impurity removal; and,

[0046] The buffer block 27 is made of elastic rubber material and is used to contact the assembly seat 4 when the elastic member 26 drives the assembly seat 4 to reset, so as to prevent the assembly seat 4 from directly colliding with the treatment pool 1 when it is reset and causing damage.

[0047] As a preferred embodiment, the flow guide mechanism of the present embodiment includes a flow guide seat 33 provided on one side of the mounting frame 5 and below the assembly seat 4, and the upper and lower sides of the flow guide seat 33 are embedded with sealing pads for contacting the outer wall of the conveyor body to ensure the sealing between the two, and the flow guide seat 33 is provided with a plurality of groups of one-way liquid inlet pipes 34 on both sides of the outer wall of the side away from the conveyor body, and one end of the one-way liquid inlet pipe 34 movably penetrates the mounting frame 5 and extends to the side of the conveyor body away from the flow guide seat 33, and the flow guide seat 33 can be set in an arc shape to guide the flow of the slurry so that the slurry flows to the one-way liquid inlet pipe 34, and the flow guide seat 33 is also penetrated with a one-way liquid outlet pipe 35 corresponding to the conveyor body, and the one-way liquid inlet pipe 34 and the one-way liquid outlet pipe 35 are both pipes with a one-way valve inside;

[0048] When the assembly seat 4 moves from one side of the inner cavity of the treatment tank 1 to the other side of the inner cavity of the treatment tank 1, the slurry located on one side of the guide seat 33 flows through the one-way liquid inlet pipe 34 to the side of the conveyor body away from the guide seat 33, such as Figure 1 As shown, when the assembly seat 4 moves from the right side of the inner cavity of the treatment tank 1 to the left side of the treatment tank 1, the slurry located on the left side of the conveyor belt body moves from the one-way liquid inlet pipe 34 to the right side of the conveyor belt body when the conveyor belt body moves. In this process, the slurry does not pass through the filter hole 8;

[0049] When the assembly seat 4 is reset, the slurry located on the side of the conveyor belt body away from the guide seat 33 passes through the filter hole 8 and is discharged from the one-way liquid outlet pipe 35 to the side of the guide seat 33 away from the conveyor belt body. When the assembly seat 4 is reset and moved from the right side of the inner cavity of the treatment tank 1 to the left side of the treatment tank 1, the slurry located on the right side of the conveyor belt body passes through the filter hole 8 and is discharged from the one-way liquid outlet pipe 35 to the left side of the guide seat 33. In this way, the slurry can be removed from impurities and iron in the process of the assembly seat 4 driving the conveyor belt body to move back and forth.

[0050] Preferably, the magnetic block 7 in this embodiment is made of magnetic rubber material.

[0051] A method for automatic permanent magnetic iron removal of ceramic slurry, using the above-mentioned automatic permanent magnetic iron removal device, comprises the following steps:

[0052] S1: Close the discharge port 3, inject the ceramic slurry into the treatment tank 1 from the feed port 2, close the feed port 2, and turn on the rotating device 9. The rotating device 9 drives a roller shaft located in the assembly seat 4 through a gear set 10, so that the roller drives the conveyor belt body to convey, and at the same time, the reciprocating mechanism drives the assembly seat 4 to drive the conveyor belt mechanism 6 to reciprocate in the treatment tank 1;

[0053] S2: When the conveyor belt mechanism 6 moves and conveys, the magnetic block 7 on its outer wall circulates into the ceramic slurry to absorb the iron impurities in the ceramic slurry. At the same time, when the assembly seat 4 is reset, the impurity particles in the ceramic slurry are filtered through the filter hole 8 under the action of the guide mechanism;

[0054] S3: The automatic cleaning mechanism cleans the iron impurities adsorbed on the magnetic block 7 and the impurity particles in the filter hole 8 into the assembly seat 4 during the conveyor belt body transmission, and extracts them to the outside through the extraction device. After the processing time is preset, the discharge port 3 is opened to discharge the ceramic slurry;

[0055] Among them, the scraper 11 scrapes off the iron impurities on the magnetic block 7, and the rotating device 9 drives the driving rod 28 to drive the cleaning member 30 to rub the conveyor belt body through the transmission member 29. Before the iron impurities on the conveyor belt body are scraped off by the scraper 11, the iron impurities and impurity particles on the conveyor belt body are preliminarily cleaned. At the same time, the transmission shaft 18 drives the speed change gear group 22 and the stirring rod 20 through the bevel gear group 19. The ceramic slurry is stirred by the rotation of the stirring rod 20, and the speed change gear group 22 enables the induced draft fan 21 to work to blow air to the conveyor belt body, so that the impurity particles in the filter hole 8 are separated from the filter hole 8 through the first air outlet end 36, and the slurry driven upward by the conveyor belt body falls back into the treatment pool 1 through the second air outlet end 37.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
