Description

Technical Field

[0001] The present invention belongs to the technical field of wollastonite production, and particularly relates to a wollastonite conveying device with a cleaning function. Background Art

[0002] Wollastonite is a triclinic system and belongs to single-chain silicate minerals. It usually occurs as sheet, radial or fibrous aggregates, white with a slight gray tint, vitreous luster, and pearly luster on cleavage planes. It is mainly produced in the contact metamorphic zone between acidic intrusive rocks and limestone, and is the main mineral component of skarn, and is also found in some high-grade metamorphic rocks. It is mainly used as raw materials or fillers for papermaking, ceramics, cement, rubber, plastics, etc.; gas filtration materials and heat insulation materials; flux for metallurgy, etc.

[0003] Wollastonite itself is a relatively pure mineral, but impurities such as soil, weeds, and rock debris may be mixed in during the mining and transportation processes. These impurities will affect the purity of wollastonite and reduce its use value. Cleaning can remove the impurities attached to the surface of wollastonite, ensure the purity of wollastonite, and make it meet the requirements of production and application.

[0004] When the existing wollastonite conveying device conveys wollastonite through a conveyor belt, most of them are provided with multiple spray heads in the conveying box to clean the conveyed wollastonite, and the impurities or sewage after cleaning will directly fall onto the conveyor belt. Therefore, the continuously operating conveyor belt will transfer some impurities or sewage to the wollastonite collection area together, which will affect the cleaning effect of wollastonite. Moreover, the impurities or sewage falling onto the conveyor belt will not only increase the overall weight of the conveyor belt and affect the difficulty of its operation, but also easily adhere to the surface of the conveyor belt and be difficult to clean.

[0014] The present invention has the following beneficial effects:

[0015] 1. In the present invention, the conveyor belt is designed as an isosceles trapezoid structure in the transfer box, and the belt body thereof adopts a chain mesh structure. The impurities and sewage after cleaning will fall into the impurity collection box through the chain mesh conveyor belt, so as to directly collect the impurities and sewage generated after cleaning. When the conveyor belt runs into the cleaning pool, at least two groups of guide rollers in the cleaning pool will guide and press the conveyor belt into the cleaning pool, so that the cleaning water in the cleaning pool will clean the impurities adhered to the surface of the conveyor belt, preventing the excessive adhesion of impurities on the surface of the conveyor belt from affecting its conveying efficiency. At the same time, the impurities and sewage generated after the wollastonite is cleaned will directly fall into the impurity collection box below and will not be transferred synchronously with the conveyor belt, and thus will not cause the overall weight of the conveyor belt to continuously increase, which is likely to cause a large amount of energy consumption during the normal operation of the conveyor belt.

[0016] 2. In the present invention, the filter screen in the impurity collection box is segmented by a lifting waste discharging assembly. When the waste discharging pipe moves downward in the impurity collection box, the filter screen made of elastic material will be in an inclined state at this time. The notch cavity and the diversion cavity on the rotated slag discharging pipe will be aligned. At this time, the rotation of the cam disc will vibrate the inclined filter screen through the vibration bumps, thereby facilitating the quick discharge and cleaning of the impurities on the filter screen, preventing excessive impurities from separating and accumulating on the filter screen and making it impossible to effectively and quickly clean. When the filter screen is in a horizontal state for normal filtration, the segmented filter screen can be supported by gravity through the connecting pipe, preventing the filter screen made of elastic material from sagging in the middle due to excessive impurities accumulating on the surface after being laid as a whole in the impurity collection box, which will affect the normal separation of sewage and mixed impurities by the filter screen.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0036] Please refer to Figures 1-6As shown in the figure, the present invention is a wollastonite conveying device with a cleaning function, including a conveying box 1. Inside the conveying box 1, a conveyor belt 2 with an isosceles trapezoidal cross-section is rotatably installed through a conveying roller 21, and the conveyor belt 2 adopts a chain mesh structure. A plurality of spray heads 3 are installed on the top of the conveying box 1, and the plurality of spray heads 3 face the upper surface of the conveyor belt 2. The conveying roller 21 located above is rotatably arranged on the left and right sides inside the conveying box 1 through the cooperation of a rotating shaft 22 and a bearing. An impurity collection box 4 is arranged inside the conveying box 1, and the impurity collection box 4 is located between the symmetrically arranged conveying rollers 21 above. The upper box opening of the impurity collection box 4 faces the surface of the conveyor belt 2. A cleaning pool 5 is fixed at the bottom of the conveying box 1, and at least two groups of guide rollers 51 are symmetrically arranged inside the cleaning pool 5. The lower belt body of the conveyor belt 2 passes through a through cavity opened on the side wall of the cleaning pool 5 and is rotatably arranged inside the cleaning pool 5, and its lower belt body is located below the guide rollers 51;

[0037] Specifically, in the present invention, the conveyor belt 2 is designed as an isosceles trapezoidal structure inside the conveying box 1, and its belt body adopts a chain mesh structure. After wollastonite falls onto the conveyor belt 2 through the feeding pipe 9 on the conveying box 1, the cleaning water in the water tank on the top of the conveying box 1 will be conveyed to the plurality of spray heads 3 through a water pump, and then sprayed onto the wollastonite being conveyed below to realize the cleaning of the impurities attached to its surface. The impurities and sewage after cleaning will fall into the impurity collection box 4 through the chain mesh type conveyor belt 2, so that the impurities and sewage generated after cleaning can be directly collected. When the conveyor belt 2 runs into the cleaning pool 5, at least two groups of guide rollers 51 in the cleaning pool 5 will guide and press the conveyor belt 2 into the cleaning pool 5, so that the cleaning water in the cleaning pool 5 will clean the impurities adhered to the surface of the conveyor belt 2, preventing the excessive adhesion of impurities on the surface of the conveyor belt 2 from affecting its conveying efficiency. At the same time, the impurities and sewage generated after the wollastonite is cleaned will directly fall into the impurity collection box 4 below and will not be transported synchronously with the conveyor belt 2, and thus will not cause the overall weight of the conveyor belt 2 to continuously increase, and thus it is not easy to cause a large amount of energy consumption during the normal operation of the conveyor belt 2.

[0038] In the design scheme of the present invention, the bottom of the impurity collection box 4 is inclined, and the middle part is in an arc-shaped depression. The front and rear width of the impurity collection box 4 is greater than the front and rear width of the conveyor belt 2. An elastic material filter screen 41 is installed inside the impurity collection box 4, and the elastic material filter screen 41 is arranged in sections. Waste discharge conduits 52 are connected to the back of the bottom of both the impurity collection box 4 and the cleaning pool 5;

[0039] Specifically, when the impurities and sewage after cleaning fall directly into the impurity collecting box 4, the filter screen 41 in the impurity collecting box 4 will intercept and separate the impurities and sewage. The separated sewage will directly gather along the inclined box wall into the arc-shaped concave bottom of the box, and then be discharged through the waste discharge duct 52. The wastewater generated after cleaning the conveyor belt 2 in the cleaning pool 5 will also be regularly discharged through the waste discharge duct 52.

[0040] In the scheme designed by the present invention, the front and rear side walls of the impurity collection box 4 are both provided with elastic rapping components 6, and the symmetrical elastic rapping components 6 are used to rap the filter screen 41 of the elastic material, and the elastic rapping components 6 include a cam plate 61, a guide slider 62, a spring member 63, a support rod 64, a rapping protrusion 65 and a toggle column 66. The rotating shaft 22 at both ends of the conveying roller 21 is sleeved with a cam plate 61, and the cam plate 61 is located on the outer side of the front and rear side walls of the impurity collection box 4, and the front and rear side walls of the impurity collection box 4 are vertically A first slide groove 42 is provided through the guide slide 62, and a guide slider 62 is slidably provided in the first slide groove 42. The bottom end of the guide slider 62 is connected to the bottom of the first slide groove 42 by a spring member 63. A support rod 64 is fixed horizontally on the guide slide 62, and the inner end of the support rod 64 extends into the impurity collection box 4 and is fixedly sleeved with a rapping protrusion 65. The rapping protrusion 65 is located above the filter screen 41. The outer end of the support rod 64 is fixedly sleeved with a toggle post 66, and the toggle post 66 is in rotational extrusion contact with the raised portion of the cam disc 61.

[0041] Specifically, when the impurities and sewage falling into the impurity collection box 4 are continuously intercepted and separated by the elastic material filter screen 41, in order to prevent the impurities from clogging the mesh of the filter screen 41 and affecting the separation of sewage, when the conveying roller 21 is continuously rotated by the output shaft of the servo motor and the rotating shaft 22, the rotating shaft 22 will drive the cam plates 61 at both ends to rotate, and when the raised portion of the cam plate 61 contacts the toggle post 66, it will generate a downward thrust on the toggle post 66, and at this time the guide slider 62 will slide downward in the first slide groove 42, the spring part 63 will be compressed, and then the support rod 64 will drive the vibration protrusion 65 at the inner end to squeeze the upper surface of the elastic material filter screen 41, and when the raised portion of the cam plate 61 is separated from the push and squeeze of the toggle post 66, the guide slider 62 will be on the spring part 63. The filter screen 41 is then moved back and forth as the guide slider 62 moves up and down, and the vibration projection 65 can continuously vibrate the filter screen 41 made of the elastic material, causing it to vibrate in the impurity collection box 4, which can not only speed up the separation efficiency of impurities and sewage falling into the impurity collection box 4, but also prevent impurities from being blocked in the mesh of the filter screen 41 and affecting its subsequent normal filtering effect. At the same time, since the conveying roller 21 is constantly rotating, it is possible to continuously provide a power source for the vibration of the filter screen 41, and there is no need to install a power source separately in the limited space to vibrate the filter screen 41, and the installation position of the vibration projection 65 and the cam plate 61 will not affect the normal operation of the filter screen 41 and the conveying roller 21.

[0042] In the design scheme of the present invention, the elastic rapping assembly 6 also includes an elastic membrane 67 and a blocking plate 68. The outer side surface of the first slide groove 42 is slidingly sealed with a segmented elastic membrane 67, and the two ends of the segmented elastic membrane 67 are respectively connected to the guide slider 62 and the upper and lower groove walls of the first slide groove 42, and the blocking plate 68 is fixed on the front and rear side walls of the impurity collection box 4, and the blocking plate 68 is located between the cam plate 61 and the end face of the conveyor belt 2; specifically, the elastic membrane 67 provided on the first slide groove 42 can not only seal the first slide groove 42 opened through, but also will not affect the normal up and down sliding of the guide slider 62; and the design of the blocking plate 68 can prevent impurities on the wollastonite from falling into the gap between the front and rear end faces of the conveyor belt 2 and the conveyor box 1, and at the same time will not interfere with the normally rotating cam plate 61.

[0043] In the design scheme of the present invention, a lifting waste discharging assembly 7 is arranged in the middle of the impurity collection box 4. The lifting waste discharging assembly 7 includes a first lifting block 71, a connecting pipe 72, a waste discharging pipe 73, an elastic sheet 74, a driving rod 75 and a slag discharging pipe 76. Second sliding grooves 43 are vertically formed in the middle of the front and rear side walls of the impurity collection box 4, and the first lifting block 71 is slidably arranged in the second sliding grooves 43. A connecting pipe 72 is fixed between the symmetric first lifting blocks 71. The corresponding ends of the segmented filter screens 41 are connected to the same connecting pipe 72. A diversion cavity 721 is formed in the connecting pipe 72 along its length direction, and the symmetric diversion cavities 721 are located on the upper surface of the filter screen 41. A waste discharging pipe 73 is rotatably inserted into the connecting pipe 72, and symmetric missing cavities 731 are also formed in the pipe wall of the waste discharging pipe 73. The lower end surface of the first lifting block 71 is connected to the bottom of the second sliding groove 43 through an elastic surface. A driving rod 75 is horizontally fixed at the end of the front side pipe orifice of the waste discharging pipe 73, and the driving rod 75 extends out of the front side of the transfer box 1. The tail of the waste discharging pipe 73 is communicated with a slag discharging pipe 76, and one end orifice of the slag discharging pipe 76 is located below the symmetric missing cavities 731. The slag discharging pipe 76 rotatably extends out of the rear side of the transfer box 1. A lifting driving assembly 8 is arranged outside the transfer box 1;

[0044] Specifically, when it is necessary to discharge the impurities collected on the filter net 41, at this time, the lifting drive assembly 8 can be used to control the symmetric first lifting blocks 71 to synchronously descend in the second sliding groove 43. At this time, the elastic sheet 74 will be compressed, causing it to drive the middle parts of the two symmetrically segmented filter nets 41 on both sides to produce downward depressions through the connecting pipe 72. Then, control the lifting drive assembly 8 to work, so that it drives the waste discharge pipe 73 to rotate in the connecting pipe 72 through the drive rod 75. Furthermore, the missing cavities 731 symmetrically opened on it are aligned with the diversion cavities 721 symmetrically opened on the connecting pipe 72. Then, the impurities accumulated on the inclined filter net 41 will be inclined and diverted through the connected diversion cavities 721 and missing cavities 731 into the waste discharge pipe 73, and then be sucked and discharged through the slag discharge pipe 76. At the same time, when the impurities on the inclined filter net 41 are discharged, the rotation of the cam disk 61 will vibrate the inclined filter net 41 through the vibration bumps 65, which is convenient for accelerating the rapid discharge and cleaning of the impurities on the filter net 41. When the impurities on the filter net 41 are cleaned up, the lifting drive assembly 8 drives the first lifting block 71 to rise in the second sliding groove 43. The elastic restoring force of the elastic sheet 74 will also generate a thrust on the first lifting block 71. Then, the waste discharge pipe 73 rotates reversely in the connecting pipe 72, so that the missing cavity 731 opened on it is disengaged from the alignment with the diversion cavity 721, so that the pipe wall of the waste discharge pipe 73 can block and seal the diversion cavity 721 opened on the connecting pipe 72, preventing the impurities normally separated on the upper surface of the filter net 41 from continuously entering the waste discharge pipe 73. When the filter net 41 is in a horizontal state for normal filtration, the segmented filter net 41 can be supported by gravity through the connecting pipe 72, preventing the filter net 41 made of elastic material from sagging in the middle due to excessive impurities accumulated on the surface after being laid entirely in the impurity collection box 4, which will affect the normal separation work of the filter net 41 for sewage and mixed impurities.

[0045] In the solution designed by the present invention, the lifting drive assembly 8 includes a second lifting block 81, a lifting cylinder 82, a sealing film 83 and a rotating disk 84. The front and rear side walls of the transfer box 1 are vertically provided with third sliding grooves 10, and a second lifting block 81 is slidably arranged in the third sliding grooves 10. The outer end of the drive rod 75 is connected to the output shaft of the servo motor fixed on the second lifting block 81. The bottom of the third sliding groove 10 is vertically fixed with a lifting cylinder 82, and the upper surface of the piston rod of the lifting cylinder 82 is connected to the second lifting block 81. The outer side slot of the second sliding groove 43 is slidably provided with a segmented sealing film 83, and the upper and lower ends of the segmented sealing film 83 are respectively connected to the first lifting block 71 and the third sliding groove 10. The second lifting block 81 slidably arranged on the rear side wall of the transfer box 1 is rotatably installed with a rotating disk 84 through a bearing, and a slag discharge pipe 76 is fixed on the rotating disk 84;

[0046] Specifically, when the connecting pipe 72 needs to descend within the impurity collection box 4, the piston rod of the lifting cylinder 82 will retract at this time, causing it to drive the second lifting block 81 to slide and descend within the third sliding groove 10. The driving rod 75 will drive the first lifting block 71 to descend within the second sliding groove 43. When the first lifting block 71 slides up and down normally, the sealing film 83 will seal the gap between the first lifting block 71 and the second sliding groove 43 to prevent sewage or impurities within the impurity collection box 4 from leaking through the gap of the second sliding groove 43. When the servo motor on the second lifting block 81 operates, it will drive the waste discharge pipe 73 to rotate through the driving rod 75, aligning the missing cavity opening 731 formed thereon with the diversion cavity 721. The slag discharge pipe 76 located at the tail of the waste discharge pipe 73 will rotate on the second lifting block 81 at the rear through the rotating disk 84, enabling the rotated slag discharge pipe 76 to always be located at the bottom of the waste discharge pipe 73, quickly discharging the impurities accumulated inside it, and not affecting the normal rotation of the slag discharge pipe 76 on the rear side wall of the transfer box 1.

[0047] In the design scheme of the present invention, a plurality of lifting rollers 44 are rotatably installed at equal intervals along the length direction of the upper box opening of the impurity collection box 4, and the lower surfaces of the belts of the plurality of lifting rollers 44 are in contact with the lower surface of the belt body of the conveyor belt 2; specifically, the design of the plurality of lifting rollers 44 can lift and support the conveyor belt 2 at the box opening of the impurity collection box 4, preventing the wollastonite continuously conveyed on the conveyor belt 2 from sinking due to its large weight, which will affect the normal conveying and processing of the wollastonite by the conveyor belt 2.

[0048] In the design scheme of the present invention, a feeding pipe 9 is connected to the left top of the transfer box 1, and a discharge cavity 11 is provided on the right side wall thereof. A guiding baffle 91 is inclinedly installed on the left inner wall of the transfer box 1, and the guiding baffle 91 is located below the feeding pipe 9. The inner wall of the cavity opening of the discharge cavity 11 is also inclinedly installed with a guiding plate 92, and the inner end of the guiding plate 92 is in contact with the end surface of the conveyor belt 2; specifically, the design of the feeding pipe 9 facilitates continuously conveying wollastonite into the transfer box 1. The opening of the discharge cavity 11 can discharge the washed wollastonite from the transfer box 1. The design of the guiding baffle 91 can block the wollastonite falling into the transfer box 1 to prevent it from directly hitting the conveyor belt 2, and the guiding plate 92 can safely and quickly guide the washed wollastonite on the conveyor belt 2 to the outside of the discharge cavity 11, so that the wollastonite will not fall into the gap between the transfer box 1 and the conveyor belt 2.
