Description

Technical Field

[0001] This invention relates to the field of feeding and conveying technology, and in particular to a potassium fluoride feeding mechanism. Background Technology

[0002] Potassium fluoride is an inorganic salt with the chemical formula KF. It is a white crystalline powder with a salty taste, is hygroscopic, soluble in water, and insoluble in ethanol. Its chemical properties are such that it only decomposes slightly when heated to its sublimation temperature. However, molten potassium fluoride is highly reactive and can corrode refractory materials. It can be used as a welding flux, insecticide, catalyst, and absorbent (to absorb HF and moisture).

[0003] In the existing potassium fluoride production process, it is first stored in a feeding funnel, and then the motor on the feeding mechanism drives the rotating shaft to rotate. A screw is fixed at the bottom of the rotating shaft that runs through the funnel. When rotating, the potassium fluoride is squeezed and fed into the processing equipment.

[0004] However, the potassium fluoride feeding mechanism still has certain drawbacks in use. Potassium fluoride is in powder form, and when it accumulates on the inner wall of the funnel, it tends to stick to the surrounding inner wall. If it stays on the inner wall for a long time, its activity will decrease by the time of the next feeding. If it is mixed with the next batch of potassium fluoride and put into the processing equipment in the next feeding process, it will affect the preparation efficiency. At the same time, if the potassium fluoride keeps sticking and does not fall off, toxic gas will be released into the air when the feed port is opened again, which will affect the surrounding environment and the personal safety of the workers. Therefore, we propose a potassium fluoride feeding mechanism. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a potassium fluoride feeding mechanism. Through the setting of cleaning components and moving components, the operator can use the original first motor in conjunction with the cleaning components and moving components to clean the potassium fluoride on the inner wall of the feeding storage chamber in an all-round way, ensuring that potassium fluoride does not stick to the inner wall, thus not affecting the preparation efficiency, and at the same time ensuring that toxic gases will not be released into the air due to residual potassium fluoride.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a potassium fluoride feeding mechanism, comprising a feeding storage bin, a feeding port, and a first motor. The feeding port is provided on the top outer wall of the feeding storage bin. The first motor is provided above the feeding storage bin. A rotating rod is connected to the output end of the first motor. The rotating rod is inserted into the top of a cleaning component. The bottom end of the cleaning component extends into the feeding storage bin. A threaded feeding rod is fixed to the bottom end of the cleaning component. A movable component is connected to the top side wall of the cleaning component. The bottom end is fixed to the outer wall of the feeding storage bin. An auxiliary component is connected to the side wall of the feeding storage bin.

[0007] The cleaning assembly includes a first movable sleeve rod that is inserted into the rotating rod and extends into the inside of the feed storage bin, a fixed plate fixed to the outer wall of the bottom end of the first movable sleeve rod, a movable part opened on the inner wall of the fixed plate, a first spring connected to the outer wall of the movable part, and a brush plate hinged to the outer end of the first spring.

[0012] The movable plate is rotatably connected to the first movable sleeve rod via a bearing.

[0013] As a preferred embodiment of the present invention, the control component includes an installation rod fixed to the outer wall of the rear end of the feeding storage bin, a fixing rod fixed to the installation rod, a second movable sleeve rod slidably connected to the fixing rod, an auxiliary plate fixed to the top of the second movable sleeve rod and fixed to the other end of the connecting rod, a placement plate fixed to the side wall of the feeding storage bin, a second motor fixed to the top of the placement plate, and a gear fixed to the output end of the second motor.

[0014] As a preferred embodiment of the present invention, the mounting rod is U-shaped and is fixed to the bottom end of the fixing rod.

[0015] As a preferred embodiment of the present invention, the outer wall of the second movable sleeve is provided with protrusions at equal intervals in the axial direction, and the protrusions are meshed with gears.

[0016] As a preferred embodiment of the present invention, the auxiliary components include two sets of mounting plates fixed on the side wall of the feeding storage bin, a rotating shaft fixed between the inner walls of the two sets of mounting plates, a rotating plate sleeved on the outer wall of the rotating shaft, a second spring connected between the rotating shaft and the rotating plate, a limiting component for limiting the rotation position of the rotating plate, a connecting plate fixed at the bottom end of the rotating plate, a brush connected to the connecting plate, and a mounting component for mounting the brush on the connecting plate.

[0017] As a preferred technical solution of the present invention, the limiting component includes an active cavity formed in the inner wall of the rotating plate, a third spring connected to the inner wall of the active cavity, a locking block fixed on the outer wall of the third spring, a sliding groove formed in the inner wall of the mounting plate, a locking hole formed in the inner wall of the mounting plate and communicating with the sliding groove, and a push rod fixed on the bottom side wall of the second active sleeve rod.

[0018] The groove is configured as an arc-shaped groove with the same rotation arc as the locking block, the outer end of the locking block is configured as a hemispherical shape, and the outer wall of the sliding end of the groove is designed as an arc surface that matches the locking block.

[0019] As a preferred embodiment of the present invention, the mounting assembly includes a mounting groove formed at the bottom end of the connecting plate and a mounting clip fixed on the brush and inserted into the mounting groove.

[0020] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0021] 1. A cleaning component and a moving component are configured. The cleaning component includes a first movable sleeve rod, a fixed plate, a movable part, a first spring, and a brush plate. The moving component includes a movable plate, a bearing, a connecting rod, an auxiliary plate, a fixed rod, a second movable sleeve rod, a placement plate, a second motor, gears, and a mounting rod. When potassium fluoride powder adheres to the inner wall of the feeding storage bin during prolonged use, the operator only needs to activate two sets of second motors. The two sets of second motors rotate in the same direction inward, causing the second movable sleeve rod to slide downward. As the second movable sleeve rod slides downward on the fixed rod, it causes the auxiliary plate to move downward. The auxiliary plate, in turn, causes the movable plate to move downward via the connecting rod. The movable plate then causes the first movable sleeve rod to slide downward on the rotating rod, and during this sliding process, it causes the fixed plate to move downward. The moving parts, the first spring, and the brush plate move downwards. During this movement, the first motor is activated, driving the rotating rod to rotate. The prism-shaped limiting engagement structure between the rotating rod and the first movable sleeve rod drives the brush plate to rotate. Two sets of gears continuously drive the second movable sleeve rod to move downwards, which in turn drives the brush plate to move downwards, thereby cleaning the inner wall of the feed storage bin from all directions. The adhering potassium fluoride powder is scraped off and falls to the bottom of the feed storage bin for continued use. This design allows workers to use the original first motor in conjunction with the cleaning and moving components to clean the potassium fluoride from the inner wall of the feed storage bin from all directions, ensuring that potassium fluoride does not adhere to the inner wall, thus not affecting the preparation efficiency, and ensuring that toxic gases will not be released into the air due to residual potassium fluoride.

[0022] 2. Using the auxiliary components, including a mounting plate, slide groove, engaging hole, rotating shaft, second spring, rotating plate, engaging block, connecting plate, mounting slot, mounting block, brush, movable cavity, third spring, and push rod, after removing the entire feed storage bin, the operator cleans the potassium fluoride accumulated on the threaded feed rod. Simply start the second motor, causing it to drive the gear to rotate. The gear then moves the second movable sleeve downwards, which in turn moves the push rod fixed to the outer wall downwards. The push rod moves until it contacts the connecting plate and pushes it downwards. At this point, the connecting plate drives the rotating plate to rotate downwards on the rotating shaft, causing the engaging block to move from the engaging hole into the slide groove, and then continuously slide out of the slide groove and separate from it. The second spring then returns to its original state from its compressed state, causing the connecting plate to rotate to the threaded feed rod. At the feed rod position, install the brush onto the connecting plate. At this time, the brush is in contact with the outer wall of the threaded feed rod. Then, start the second motor to drive the second movable sleeve rod upward. The second movable sleeve rod drives the threaded feed rod upward back to its original position. Then, start the second motor to drive the threaded feed rod downward. At the same time, start the first motor to drive the threaded feed rod to rotate, so that the threaded feed rod moves out of the bottom of the feed storage bin and rotates itself to cooperate with the brush to scrape off and collect all the potassium fluoride powder hidden on the brush. When it is not needed, remove the brush. Then, the operator moves the connecting plate upward, so that the rotating plate rotates on the rotating shaft, thereby squeezing the second spring to deform and drive the locking block to move into the slide groove. Then, it continues to move into the locking hole to form a lock, so that the rotating plate is in a locked and stationary state on the rotating shaft, which will not affect the normal operation of the equipment.

[0023] 3. With the installation components, which include a connecting plate, a mounting slot, a mounting clip, and a brush, the operator can insert the brush into the mounting slot via the mounting clip to form a locking mechanism. This makes it easy to replace the brush when it is damaged after long-term use. At the same time, it ensures that when the connecting plate is moved up and down, the brush can be removed and the upward rotation of the connecting plate will not obstruct the up and down movement of the second movable sleeve.

Detailed Implementation

[0036] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0037] Example:

[0038] like Figure 1 - Figure 11As shown, it includes a feeding storage bin 1, a feeding port 2, and a first motor 3. The feeding port 2 is provided on the top outer wall of the feeding storage bin 1. The first motor 3 is provided above the feeding storage bin 1. The output end of the first motor 3 is connected to a rotating rod 4. The rotating rod 4 is inserted into the top of the cleaning component 6. The bottom end of the cleaning component 6 extends into the feeding storage bin 1. A threaded feeding rod 5 is fixed to the bottom end of the cleaning component 6. A moving component 7 is connected to the top side wall of the cleaning component 6. The bottom end is fixed to the outer wall of the feeding storage bin 1. An auxiliary component 8 is connected to the side wall of the feeding storage bin 1.

[0039] like Figure 7 As shown, the cleaning assembly 6 includes a first movable sleeve rod 61 that is inserted into the rotating rod 4 and extends into the inside of the feeding storage bin 1, a fixing plate 62 fixed to the outer wall of the bottom end of the first movable sleeve rod 61, a movable part 63 opened on the inner wall of the fixing plate 62, a first spring 64 connected to the outer wall of the movable part 63, and a brush plate 65 hinged to the outer end of the first spring 64.

[0040] The bottom end of the fixed plate 62 is fixed with a threaded feed rod 5, the bottom end of which passes through the feed storage bin 1. The movable part 63 includes a telescopic bin opened in the fixed plate 62 and a telescopic rod that is slidably connected to the telescopic bin and has a first spring 64 sleeved on its outer wall.

[0041] like Figure 4 - Figure 6 As shown, the moving component 7 includes a movable plate 71 sleeved on the outer wall of the top end of the first movable sleeve rod 61, a bearing 72 opened in the movable plate 71, a connecting rod 73 fixed on the side wall of the movable plate 71, and a control component fixed to the outer wall of the other end of the connecting rod 73. The movable plate 71 is rotatably connected to the first movable sleeve rod 61 through the bearing 72. The control component includes an mounting rod 710 fixed on the outer wall of the rear end of the feeding storage bin 1, a fixing rod 75 fixed on the mounting rod 710, a second movable sleeve rod 76 slidably connected to the fixing rod 75, an auxiliary plate 74 fixed to the top end of the second movable sleeve rod 76 and fixed to the other end of the connecting rod 73, a placement plate 77 fixed to the side wall of the feeding storage bin 1, a second motor 78 fixed to the top end of the placement plate 77, and a gear 79 fixed to the output end of the second motor 78.

[0042] When potassium fluoride powder adheres to the inner wall of the feeding storage bin 1 during prolonged use, the operator only needs to start two sets of second motors 78. The two sets of second motors 78 rotate in the same direction inward, thereby driving the second movable sleeve rod 76 to slide downward through the gear 79. The outer wall of the second movable sleeve rod 76 is provided with protrusions at equal intervals in the axial direction. The protrusions mesh with the gear 79 to ensure that the gear 79 can drive the second movable sleeve rod 76 to move up and down. During the downward sliding of the second movable sleeve rod 76 on the fixed rod 75, it drives the auxiliary plate 74 to move downward. The fixed rod 75 is fixed to the outer wall of the feeding storage bin 1 by the mounting rod 710. The mounting rod 710 is U-shaped and fixed to the bottom end of the fixed rod 75. The auxiliary plate 74 drives the movable plate 71 to move downward through the connecting rod 73. The movable plate 71 drives the first movable sleeve rod 61 to slide downward on the rotating rod 4. During the sliding process, it drives the fixed plate 62, the movable part 63, the first spring 64 and the brush plate 65 to move downward. During the movement, the first motor 3 is started to drive the rotating rod 4 to rotate.

[0043] like Figure 8 As shown, the rotating rod 4 is prismatic in shape and is rotatably limited by the first movable sleeve rod 61. The rotating rod 4 can be a triangular prism, quadrangular prism, or pentagonal prism, etc. The prismatic limiting engagement structure between the rotating rod 4 and the first movable sleeve rod 61 drives the brush plate 65 to rotate. The two sets of gears 79 continuously drive the second movable sleeve rod 76 to move downward, which in turn drives the brush plate 65 to move downward. One end of the first spring 64 is connected to the outer wall of the fixed plate 62, and the other end of the first spring 64 is connected to the outer wall of the brush plate 65. The deformation length of the first spring 64 is equal to the inclination distance of the inner wall of the feed storage bin 1. The brush plate 65 is provided with a hinge and the first spring. With the 64 movable connection, during the downward movement, the brush plate 65 presses inward against the first spring 64, ensuring that the brush plate 65 remains in contact with the inclined inner wall of the feed storage chamber 1. This allows for comprehensive cleaning of the inner wall of the feed storage chamber 1, scraping off the adhering potassium fluoride powder, which then falls to the bottom of the feed storage chamber 1 for continued use. This design enables workers to use the original first motor 3 in conjunction with the cleaning component 6 and the moving component 7 to comprehensively clean the potassium fluoride on the inner wall of the feed storage chamber 1, ensuring that potassium fluoride does not adhere to the inner wall, thus not affecting the preparation efficiency, and also ensuring that residual potassium fluoride does not cause toxic gases to escape into the air.

[0044] like Figure 9 - Figure 11As shown, the auxiliary component 8 includes two sets of mounting plates 81 fixed on the side wall of the feed storage bin 1, a rotating shaft 84 fixed between the inner walls of the two sets of mounting plates 81, a rotating plate 86 sleeved on the outer wall of the rotating shaft 84, a second spring 85 connected between the rotating shaft 84 and the rotating plate 86, a limiting component for limiting the rotation position of the rotating plate 86, a connecting plate 88 fixed at the bottom end of the rotating plate 86, a brush 811 connected to the connecting plate 88, and a mounting component for mounting the brush 811 on the connecting plate 88.

[0045] The limiting assembly includes a movable cavity 812 formed in the inner wall of the rotating plate 86, a third spring 813 connected to the inner wall of the movable cavity 812, a locking block 87 fixed to the outer wall of the third spring 813, a slide groove 82 formed in the inner wall of the mounting plate 81, a locking hole 83 formed in the inner wall of the mounting plate 81 and communicating with the slide groove 82, and a push rod 814 fixed to the bottom side wall of the second movable sleeve 76.

[0046] The slide groove 82 is set as an arc-shaped groove with the same rotation arc as the locking block 87. The outer end of the locking block 87 is set as a hemispherical shape. The outer wall of the sliding end of the slide groove 82 is designed as an arc surface that matches the locking block 87.

[0047] After removing the entire feed storage bin 1, the staff cleaned the potassium fluoride accumulated on the threaded feed rod 5. This was done by starting the second motor 78, which drove the gear 79 to rotate. The gear 79 then moved the second movable sleeve 76 downwards, which in turn moved the push rod 814 fixed to the outer wall downwards. The push rod 814 moved until it contacted the connecting plate 88 and pushed downwards. At this point, the connecting plate 88 caused the rotating plate 86 to rotate downwards on the rotating shaft 84, causing the locking block 87 to move from the locking hole 83 into the slide groove 82, and then slide out of and separate from the slide groove 82. The second spring 85, which is a torsion spring, then returned to its original state from the compressed state, causing the connecting plate 88 to rotate to the position of the threaded feed rod 5. The brush 811 was then installed on the connecting plate 88, and at this point, the brush 811 was in contact with the outer wall of the threaded feed rod 5. The second motor 78 can be started to drive the second movable sleeve 76 to move upward. The second motor 78 is a servo motor. The second movable sleeve 76 drives the threaded feed rod 5 to move upward to its original position. Then, the second motor 78 is started again to drive the threaded feed rod 5 to move downward. At the same time, the first motor 3 is started to drive the threaded feed rod 5 to rotate, so that the threaded feed rod 5 moves out of the bottom of the feed storage bin 1 and rotates itself to cooperate with the brush 811 to scrape off and collect all the potassium fluoride powder hidden on the brush 811. When it is not needed, the brush 811 is removed. Then, the operator moves the connecting plate 88 upward, so that the rotating plate 86 rotates on the rotating shaft 84, thereby squeezing the second spring 85 to deform and drive the locking block 87 to move into the slide groove 82. Then, it continues to move into the locking hole 83 to form a lock, so that the rotating plate 86 is in a locked and stationary state on the rotating shaft 84, which will not affect the normal operation of the equipment.

[0048] The mounting components include a mounting groove 89 formed at the bottom end of the connecting plate 88 and a mounting clip 810 fixed to the brush 811 and inserted into the mounting groove 89.

[0049] With the installation components included, such as a connecting plate 88, a mounting slot 89, a mounting block 810, and a brush 811, the operator can insert the brush 811 into the mounting slot 89 via the mounting block 810 to form a locking mechanism. This makes it easy to replace the brush 811 if it is damaged after long-term use. At the same time, it ensures that when the connecting plate 88 is moved up and down, the brush 811 can be removed, and the upward rotation of the connecting plate 88 will not obstruct the up and down movement of the second movable sleeve 76.

[0050] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
