Description

Technical Field

[0001] The invention belongs to the technical field of dust removal in calcium fluoride production, in particular to a dust removal device for clean production of calcium fluoride. Background Art

[0002] The recycling of calcium fluoride sludge, a general solid waste, has become a key issue for environmental protection and sustainable development. With technological advancements and rising environmental awareness, more and more companies are focusing on solutions in this area to maximize resource utilization and minimize environmental pollution. Therefore, the recycling of calcium fluoride from solid waste calcium fluoride sludge is a key project. Currently, the main technical approaches for recycling calcium fluoride sludge include physical, chemical, and biological methods. Physical methods primarily treat sludge through physical means such as crushing, screening, and drying to remove moisture and impurities, thereby improving recovery efficiency. Chemical methods, combined with the addition of chemical reagents, convert the calcium fluoride in the sludge into recyclable substances.

[0003] The existing solid waste calcium fluoride sludge is first dried to remove moisture, and the dried sludge blocks are then broken into small pieces and fed into subsequent processes from a discharge port to be converted into products. During this crushing and feeding process, a large amount of dust particles are generated. Relying solely on suction and absorption makes the collection insufficient, and the crushed dust particles are easily sucked away. Ultimately, the actual amount of sludge entering the equipment will be reduced, affecting the final calcium fluoride production. Summary of the Invention

DETAILED DESCRIPTION

[0041] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. 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.

[0042] Example 1

[0043] See also Figure 1 - Figure 7 The present application provides a dust removal device for clean production of calcium fluoride, comprising:

[0044] The dust collection device 200 is installed between the crushing device 100 and the soaking device 300. The dust collection device 200 can surround the dust particles generated during the crushing process of the dried sludge blocks to prevent the dust particles from escaping. At the same time, the dust particles are sprayed and fall on the vibrating discharge plate 201. The fallen dust clusters are then pushed and collected, thereby reducing the impact on the surrounding environment, reducing the waste of dust particles from the dried sludge blocks, and increasing the amount of calcium fluoride crystals collected subsequently.

[0045] The dust collecting device 200 includes a vibrating discharge plate 201 obliquely installed below the discharge port of the crushing device 100. Similarly, the crushing device 100 is an existing dried sludge block crusher, which is a prior art and will not be explained in detail. A plurality of elastic vibrating members 202 are provided between the vibrating discharge plate 201 and the crushing device 100, and a vibrating motor is provided on the inclined lower surface of the vibrating discharge plate 201. As the vibrating motor cooperates with the elastic vibrating member 202, the cooperation principle of the two is a prior art and will not be explained in detail here, and the vibrating discharge plate 201 is repeatedly vibrated, which facilitates the discharge and collection of dust particles and dried sludge block particles in the vibrating discharge plate 201. A surrounding sedimentation member 203 is provided between the vibrating discharge plate 201 and the crushing device 100 to prevent the dried sludge block dust from escaping. A collecting and discharge member 204 is provided on the surface of the vibrating discharge plate 201 to crush the dried sludge block particles falling inside the vibrating discharge plate 201 again.

[0046] The agitating member 205 agitates the dried sludge cakes dropped into the soaking device 300 .

[0047] In this embodiment, preferably, the surrounding sedimentation member 203 includes a rectangular frame 2031 fixed to the bottom of the crushing device 100, and an inner surrounding layer 2037 is provided between the lower surface of the rectangular frame 2031 and the upper surface of the vibrating blanking plate 201. The inner surrounding layer 2037 can be a dustproof cloth layer, which surrounds the space between the vibrating blanking plate 201 and the crushing device 100 to reduce the dust of the dried sludge block from escaping to the outside. The upper surface of the soaking device 300 is provided with an outer surrounding layer 2033 connected to the inner surrounding layer 2037, and the outer surrounding layer 2033 is provided on the vibrating blanking plate 201. The space between the material plate 201 and the soaking device 300 is surrounded, and the outer surrounding layer 2033 is also a dust-proof cloth layer, which has a certain ductility and will not affect the slight vibration of the vibrating blanking plate 201. There is space on the left side of the outer surrounding layer 2033 for the right end of the vibrating blanking plate 201 to pass through, which will not affect the blanking of the vibrating blanking plate 201. A supporting cross plate 2034 is provided on the right side of the crushing device 100 to support and fix the outer surrounding layer 2033, which plays an opening and supporting role for the outer surrounding layer 2033, providing sufficient space for the vibrating blanking plate 201 to vibrate and blank.

[0048] In this embodiment, preferably, the rectangular frame 2031 includes a water tank 2032 and a horizontal water pipe 2035 on the outer surface. The inner surface of the horizontal water pipe 2035 is provided with a mist nozzle 2036 that is obliquely penetrated through the rectangular frame 2031 and exposed on the inner side. The mist nozzle 2036 is inclined downward, which is convenient for clumping the flying dried sludge block dust and attaching it to the inner enclosure layer 2037 and the surface of the vibrating blanking plate 201. The inner enclosure layer 2037 is installed on the vibrating blanking plate 201 to prevent the dried sludge block dust from escaping. At the same time, as the vibrating blanking plate 201 vibrates synchronously, the dried sludge block dust attached to the inner surface of the inner enclosure layer 2037 is shaken and falls into the vibrating blanking plate 201, which is convenient for collecting dust. The surface of the water tank 2032 is provided with a water pump 2038 that supplies water to the horizontal water pipe 2035.

[0049] In this embodiment, preferably, the collecting and unloading component 204 can be used to knock the dried sludge block particles that fall into the vibrating unloading plate 201 again, so as to break up the larger dried sludge block particles again, which is convenient for subsequent collection and soaking. At the same time, the dust particles in the vibrating unloading plate 201 are pushed downward for collection. The collecting and unloading component 204 that breaks up the dried sludge block particles inside the vibrating unloading plate 201 again includes:

[0050] The central shaft 2041 is longitudinally distributed inside the vibration blanking plate 201, and the outer end of the central shaft 2041 is provided with a vertical plate 2043. The circumferential surface of the central shaft 2041 is provided with a plurality of U-shaped knocking blanking plates 2042. Figure 10 For example, one of the U-shaped knocking blanking plates 2042 is composed of a vertical end and a horizontal end formed by two electric telescopic rods, which is convenient for changing the distance between the horizontal end and the vibrating blanking plate 201, and when pushing the material, the knocking blanking plate 2042 that can change the height can contact the inner surface of the vibrating blanking plate 201. As the central shaft 2041 rotates, multiple knocking blanking plates 2042 rotate to crush the dried sludge block particles inside the vibrating blanking plate 201 again, which is convenient for subsequent full soaking, dust removal and cleaning. Rectangular holes are opened on the front and back surfaces of the vibrating blanking plate 201 to facilitate the central shaft 2041 It slides in the rectangular hole, and the diameter of the central shaft 2041 is smaller than the width of the rectangular hole, so that the central shaft 2041 can be lifted to a certain height by the lifting cylinder 20443. The lifted height is sufficient to disengage the rotating gear 2046 from the mounting rack 2047. A shielding plate is provided on the central shaft 2041 to block the rectangular hole. The length and width of the shielding plate can be set according to actual needs, but the rectangular hole can always be blocked without affecting the movement of the central shaft 2041. At the same time, the dust of the dried sludge block is reduced from escaping from the rectangular hole. The outer end of the central shaft 2041 passes through the rectangular hole and is hugged on the outside.

[0051] A rotating gear 2046 is sleeved on the outer end of the central shaft 2041. External fixing plates 2045 are provided on the front and rear surfaces of the vibrating blanking plate 201. A mounting rack 2047 is provided on the upper surface of the external fixing plate 2045 and is engaged with the rotating gear 2046. The rotating gear 2046 cooperates with the mounting rack 2047, and the rotatable gear 2046 rotates while moving along the vibrating blanking plate 201, thereby crushing the dried sludge block particles again, so that the small particles of dried sludge block can be fully immersed in the reaction and converted.

[0052] The telescopic cylinder 2044 drives the central shaft 2041 to move along the tilting direction of the vibrating blanking plate 201, thereby driving the central shaft 2041 and the knocking blanking plate 2042 to move downward to push the material.

[0053] In this embodiment, preferably, a slide 2048 is provided on the outer end of the central shaft 2041, the piston rod inside the telescopic cylinder 2044 is connected to the slide 2048, and the slide 2048 is slidably connected to the slideway provided on the outer fixed plate 2045, which limits the movement of the central shaft 2041 without affecting the upward lifting of the central shaft 2041.

[0054] In summary, the vibrating blanking plate 201 vibrates under the action of the vibrating motor, driving the inner and outer surrounding layers 2037 and 2033 to vibrate, and the dried sludge blocks are fed from the feed port of the crushing device 100 and crushed, and the crushed dried sludge block particles fall from the feed port to the inside of the vibrating blanking plate 201, and fall down along the inclined surface of the vibrating blanking plate 201 for collection. The inner and outer surrounding layers 2037 and 2033 vibrate continuously, making it difficult for the dried sludge block dust to adhere to the surface and keep it in a flying state. The water pump 2038 works to suck the water in the water tank 2032 into the horizontal water pipe 2035, and discharges it from multiple mist nozzles 2036, where it mixes with the flying dried sludge dust, and the agglomerated dried sludge dust falls. In the vibrating blanking plate 201, the atomized liquid is clean and will not cause any additional impact on the dried sludge. Instead, it facilitates the dust sedimentation. As the vibrating blanking plate 201 vibrates and discharges the dust, and for the agglomerated dust that cannot be completely shaken out in the vibrating blanking plate 201, the piston rod inside the lifting cylinder 20443 can be extended, the rotating gear 2046 is not engaged with the mounting rack 2047, and the piston rod inside the telescopic cylinder 2044 is retracted, driving the knocking blanking plate 2042 to move to the left. The electric telescopic rod of the knocking blanking plate 2042, which is located at the leftmost end of the vibrating blanking plate 201 and can change the height, is extended, driving the horizontal end to extend beyond the distance of other knocking blanking plates 2042 to contact the vibrating blanking plate. The inner surface of the material plate 201, as the piston rod inside the telescopic cylinder 2044 extends, drives the central shaft 2041 and the knocking blanking plate 2042 to move, and pushes the agglomerated dust attached to the inner surface of the vibrating blanking plate 201 to fall into the soaking device 300 for collection and soaking, thereby realizing the collection of the agglomerated dust. When it is in the state of large-particle dried sludge blocks, all the knocking blanking plates 2042 are consistent in size and height, the piston rod inside the lifting cylinder 20443 remains retracted, and the rotating gear 2046 is engaged with the mounting rack 2047. At this time, the knocking blanking plate 2042 is also located at the left end of the vibrating blanking plate 201. As the piston rod inside the telescopic cylinder 2044 extends, the rotating gear 2 046 rotates and moves along the mounting rack 2047. Since the slide 2048 is rotationally connected to the central shaft 2041, the rotation of the central shaft 2041 is not affected. The central shaft 2041 will drive multiple knocking and unloading plates 2042 to rotate and move, and knock and break the large-particle dried sludge blocks in the vibrating unloading plate 201 again. The knocking and unloading plate 2042 rotates clockwise, which has a centrifugal force to discharge the large-particle dried sludge blocks downward, making it convenient for the dried sludge block particles to be further discharged, and the dried sludge block particles are broken again into smaller pieces, so that they can be fully soaked by the soaking device 300 and facilitate subsequent calcium fluoride treatment. When the knocking and unloading plate 2042 returns to its original position to the left, it can cooperate with the lifting component.

[0055] Example 2

[0056] Reference Figure 5 - Figure 7, which is the second embodiment of the present invention.

[0057] In this embodiment, preferably, a lifting component is provided between the telescopic cylinder 2044 and the vibrating blanking plate 201. The lifting component can be used to change the distance between the knocking blanking plate 2042 and the inner surface of the vibrating blanking plate 201, so that the knocking blanking plate 2042 will not push the dried sludge block upward when it moves to the left and is located at the left end of the vibrating blanking plate 201. It is convenient for the knocking blanking plate 2042 to stably push the material downward from the left end of the vibrating blanking plate 201, so that the dried sludge block dust particles and the like that fall on the vibrating blanking plate 201 can be discharged and collected into the soaking device 300. The lifting component includes:

[0058] A stabilizing seat 20441 is sleeved on the telescopic cylinder 2044, and an extension plate 20442 is provided on the inner surface of the stabilizing seat 20441;

[0059] The support base 20444 is fixed on the outer surface of the vibrating blanking plate 201, and a lifting cylinder 20443 is embedded inside the support base 20444. The piston rod inside the lifting cylinder 20443 is connected to the lower surface of the extension plate 20442. The lifting cylinder 20443 can drive the extension plate 20442 to move upward, and the moving direction is perpendicular to the inclination of the telescopic cylinder 2044, which is convenient for changing the height of the center axis 2041 and the knocking blanking plate 2042, so that the knocking blanking plate 2042 is located to the left at the left end of the vibrating blanking plate 201.

[0060] In summary, when the lifting cylinder 20443 is not working, the piston rod inside the lifting cylinder 20443 is in a retracted state, the knocking blank plate 2042 just contacts the inner surface of the vibrating blank plate 201, and the rotating gear 2046 is engaged with the mounting rack 2047. At this time, when it is necessary to change the height of the knocking blank plate 2042, the lifting cylinder 20443 can be operated, and the internal piston rod extends to drive the telescopic cylinder 2044 to move upward, and at the same time as the telescopic cylinder 2044 moves, it drives the slide 2048 and the center shaft 2041 to move upward, and the rotating gear 2046 is disengaged from the mounting rack 2047, and the knocking blank plate 2042 is kept at a certain distance from the vibrating blank plate 201. As the telescopic cylinder 2044 moves, the sliding seat 2048 and the center shaft 2041 are disengaged. The piston rod inside 044 retracts, driving the knocking blanking plate 2042 to move to the left without pushing the material, until the knocking blanking plate 2042 is located at the leftmost end of the vibrating blanking plate 201, and one of the electric telescopic rods of the knocking blanking plate 2042 extends, driving the horizontal end to extend and contact the inner surface of the vibrating blanking plate 201, and the telescopic cylinder 2044 works again, and the piston rod inside the telescopic cylinder 2044 extends to drive the knocking blanking plate 2042 to move along the vibrating blanking plate 201, pushing the dried sludge block particles and dust on the inner surface of the vibrating blanking plate 201 downward for collection. During the whole process, dust adhesion to the inner wall of the vibrating blanking plate 201 is avoided, and the dust collection amount of the dried sludge block is increased, thereby increasing the subsequent calcium fluoride crystallization amount.

[0061] Example 3

[0062] Reference Figure 6 、 Figure 8 and Figure 9 , which is the third embodiment of the present invention.

[0063] In this embodiment, preferably, by providing a stirring member 205, the dried sludge blocks accumulated in the soaking device 300 can be fully stirred in the front, back, left, and right directions, thereby improving the adequacy of removing dust impurities mixed in the dried sludge blocks during the soaking process, and preventing dust from escaping during the stirring process, thereby improving the purity of subsequent calcium fluoride crystallization. The stirring member 205 for moving the dried sludge blocks immersed in the soaking device 300 includes:

[0064] The two connecting plates 206 on the left side of the soaking device 300 are obliquely passed through. When the connecting plate 206 is located at the leftmost side, the longitudinal seat 2051 is close to the left inner wall of the soaking device 300 and will not separate from the soaking device 300. A dustproof cloth can also be set between the left end of the connecting plate 206 and the left outer surface of the soaking device 300. This is not drawn in the drawings of this application. It does not affect the movement of the connecting plate 206 and will shield the connection to prevent the dust of the limestone dried sludge block from escaping outward. A longitudinal seat 2051 is set between the right ends of the two connecting plates 206. An inner slide rod 2052 is slidingly set inside the longitudinal seat 2051. Both ends of the inner slide rod 2052 exceed the end of the longitudinal seat 2051.

[0065] The front fixed wedge 2055 and the rear guide wedge 2058 are installed on the front and rear inner walls of the immersion device 300. The front fixed wedge 2055 and the rear guide wedge 2058 are arranged with their inclined surfaces facing each other, and the front fixed wedge 2055 is located on the right side of the rear guide wedge 2058.

[0066] The front guide wedge 2056 and the rear fixed wedge 2057 are respectively installed at both ends of the inner slide bar 2052, and the front guide wedge 2056 and the rear fixed wedge 2057 are respectively matched with the front fixed wedge 2055 and the rear guide wedge 2058.

[0067] In this embodiment, preferably, a plurality of vertical rods 2053 are vertically arranged on the right side of the inner sliding rod 2052, and a plurality of material-moving inclined rods 2054 are obliquely arranged on the vertical rod 2053. The inner sliding rod 2052 and the material-moving inclined rod 2054 can move the dried sludge block particles in the soaking device 300, thereby facilitating the full soaking of the dried sludge block particles, improving the impurity removal effect, and increasing the purity of subsequent calcium fluoride crystallization.

[0068] In this embodiment, preferably, a vertically distributed long hole is opened on the left side of the immersion device 300. The height of the vertically distributed long hole is located above the liquid in the immersion device 300, which will not cause leakage of the liquid in the immersion device 300. A guide slider 2059 is provided on the inner wall of the long hole.

[0069] In this embodiment, preferably, an inclined long hole is opened on the surface of the connecting plate 206, and the guide slider 2059 slides in the inclined long hole. The two slide together to guide the movement of the connecting plate 206. The inclined upper end of the connecting plate 206 is connected to the vertical plate 2043, so that it can move together with the vertical plate 2043.

[0070] In summary, when in use, when the central shaft 2041 moves along the vibrating blanking plate 201, it drives the vertical plate 2043 and the connecting plate 206 to move. When the connecting plate 206 moves, the dustproof cloth moves with the movement of the connecting plate 206 and will not affect the movement of the connecting plate 206. When the connecting plate 206 moves to the right, it drives the longitudinal seat 2051 and the inner slide bar 2052 to move to the right. The rear fixed wedge block 2057 moves to the right and gradually moves away from the rear guide wedge block 2058, while the front guide wedge block 2056 moves to the right and gradually approaches the front fixed wedge block 2055. The inner slide bar 2052 The vertical rod 2053 and the diagonal rod 2054 on it are driven to move, and the dried sludge blocks immersed in the immersion device 300 are moved, and the accumulated dried sludge blocks are stirred, so that they can be fully immersed in the liquid in the immersion device 300, and the liquid is used to react and transform the substances in the dried sludge blocks. The immersion device 300 can be provided with multiple channels according to the transformation conditions. It is a prior art. When the inclined surface of the front guide wedge block 2056 fits with the inclined surface of the front fixed wedge block 2055, as the inner slide bar 2052 continues to move, the inclined surface fits so that the inner slide bar 2052 moves backward, and at the same time drives the rear fixed wedge block 2055 to move backward. The fixed wedge block 2057 is close to the rear guide wedge block 2058, and the height of the front fixed wedge block 2055 can be set according to the needs, which is sufficient to adapt to the change of the height of the connecting plate 206, ensuring that the front guide wedge block 2056 is always in contact with the front fixed wedge block 2055 during the movement. Similarly, the thickness of the rear guide wedge block 2058 is also adapted to the movement of the rear fixed wedge block 2057. The backward movement of the inner slide bar 2052 will drive the vertical rod 2053 and the material diagonal rod 2054 to move backward. When the connecting plate 206 moves to the right end limit position, it stops moving, and the connecting plate 206 moves along the center axis 2 When 041 moves to the left, the front guide wedge 2056 gradually moves away from the front fixed wedge 2055, and the distance between the rear fixed wedge 2057 and the rear guide wedge 2058 gradually decreases until the inclined surfaces of the two are in contact. As the movement occurs, the inner sliding rod 2052 and the vertical rod 2053 move to the left and forward at the same time, fully stirring the dried sludge blocks in the immersion device 300. During the whole process, the dried sludge blocks accumulated in the immersion device 300 are stirred back and forth and left and right, which facilitates the dried sludge blocks to be fully immersed and removed of impurities, thereby improving the purity of the subsequent calcium fluoride crystallization of the dried sludge blocks.

[0071] Example 4

[0072] This embodiment is obtained by combining the first embodiment, the second embodiment and the third embodiment.

[0073] During use, the surrounding sedimentation component 203 is utilized to prevent the dried sludge block dust from being wasted during the crushing and feeding to the soaking process, and the flying dried sludge block dust is settled and collected. While collecting, the settled agglomerated dust is quickly fed into the soaking process. While collecting the dust, the dried sludge block particles are crushed again to reduce the particle diameter, thereby facilitating the full soaking of the dried sludge block particles and facilitating subsequent reaction treatment.

[0074] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
