Description

Technical Field

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

[0002] Wollastonite is a triclinic crystal system and belongs to a single-chain silicate mineral. It is usually in the form of flaky, radial or fibrous aggregates. It is white with a slight gray hue, has a glassy luster, and has a pearly luster on the cleavage surface. It is mainly produced in the contact metamorphic zone between acidic intrusive rocks and limestones. It is the main mineral component of skarn and is also found in some deep metamorphic rocks. It is mainly used as a raw material or filler for papermaking, ceramics, cement, rubber, plastics, etc.; gas filtration materials and thermal insulation materials; flux for metallurgy, etc.

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

[0004] When existing wollastonite conveying devices convey wollastonite through a conveyor belt, most of them are equipped 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 running conveyor belt will transport some impurities or sewage to the wollastonite collection area, which will affect the cleaning effect of the wollastonite. The impurities or sewage falling on the conveyor belt will not only increase the overall weight of the conveyor belt and affect the difficulty of its operation, but also make it easy for impurities and sewage to adhere to the surface of the conveyor belt and make it difficult to clean.

[0015] 1. The present invention designs the conveyor belt to be an isosceles trapezoidal structure in the conveying box, and the belt body adopts a chain net structure, and the cleaned impurities and sewage will fall into the impurity collection box through the chain net conveyor belt, so that the impurities and sewage generated after cleaning can be directly collected, and when the conveyor belt runs into the cleaning pool, at least two groups of guide rollers in the cleaning pool will guide the conveyor belt to press it 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, and prevent the impurities adhered to the surface of the conveyor belt from being excessive and affecting its transmission efficiency.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection 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", "inside", "all around" and the like 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 therefore should not be understood as limiting the present invention.

[0036] See also Figure 1-Figure 6As shown, the present invention is a wollastonite conveying device with a cleaning function, comprising a conveying box 1, wherein a conveying belt 2 with an isosceles trapezoidal cross-section is rotatably installed inside the conveying box 1 through a conveying roller 21, and the conveying belt 2 adopts a chain network 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 conveying belt 2, and the conveying roller 21 located above is arranged on the left and right sides of the conveying box 1 through the cooperation and rotation of the rotating shaft 22 and the bearing, an impurity collecting box 4 is arranged inside the conveying box 1, and the impurity collecting box 4 is located between the upper symmetrical conveying rollers 21, and the upper box opening of the impurity collecting box 4 faces the surface of the conveying belt 2, a cleaning tank 5 is fixed at the bottom of the conveying box 1, and at least two groups of guide rollers 51 are symmetrically arranged in the cleaning tank 5, and the lower belt body of the conveying belt 2 passes through the through cavity opened in the side wall of the cleaning tank 5 and is rolled in the cleaning tank 5, and its lower belt body is located below the guide roller 51;

[0037] Specifically, the present invention designs the conveyor belt 2 as an isosceles trapezoidal structure in the conveyor box 1, and the belt body adopts a chain net structure. When the wollastonite falls onto the conveyor belt 2 through the feed pipe 9 on the conveyor box 1, the cleaning water in the water tank on the top of the conveyor box 1 will be transported to multiple spray heads 3 through a water pump, and then sprayed onto the wollastonite being conveyed below, so as to clean the impurities attached to the surface thereof, and the cleaned impurities and sewage will fall into the impurity collection box 4 through the chain net conveyor belt 2, so that the impurities and sewage generated after cleaning can be directly collected, and when the conveyor belt 2 is running When it is transferred to the cleaning tank 5, at least two sets of guide rollers 51 in the cleaning tank 5 will guide and press the conveyor belt 2 into the cleaning tank 5, so that the cleaning water in the cleaning tank 5 will clean the impurities adhered to the surface of the conveyor belt 2, to prevent excessive impurities adhered to the surface of the conveyor belt 2 and affect its transmission efficiency. At the same time, the impurities and sewage generated after the silica gel is cleaned will directly fall into the impurity collection box 4 below, and will not be transported synchronously with the conveyor belt 2, thereby not causing the overall weight of the conveyor belt 2 to continue to increase, and thus easily causing the conveyor belt 2 to generate a large amount of energy consumption during normal operation.

[0038] In the scheme designed by the present invention, the bottom of the impurity collection box 4 is inclined, and the middle part thereof is an arc-shaped concave shape. The front-to-back width of the impurity collection box 4 is greater than the front-to-back width of the conveyor belt 2. A filter screen 41 made of elastic material is installed in the impurity collection box 4, and the filter screen 41 made of elastic material is arranged in sections. The impurity collection box 4 and the back of the bottom of the cleaning tank 5 are both connected with a waste discharge duct 52.

[0039] Specifically, when the impurities and sewage after cleaning fall directly into the impurity collecting box 4, the filter net 41 in the impurity collecting box 4 will intercept and separate the impurities and sewage, and the separated sewage will directly gather in the arc-shaped concave bottom of the box along the inclined box wall, 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 cam plates 61 are sleeved on the rotating shafts 22 at both ends of the conveying roller 21, and the cam plates 61 are located on the outer side surfaces of the front and rear side walls of the impurity collection box 4. 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 through a spring member 63. A support rod 64 is horizontally fixed 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. A toggle column 66 is fixedly sleeved on the outer end of the support rod 64, and the toggle column 66 is in rotational extrusion contact with the raised portion of the cam plate 61.

[0041] Specifically, when the impurities and sewage falling into the impurity collection box 4 are continuously intercepted and separated by the filter screen 41 made of elastic material, 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, a downward thrust is generated on the toggle post 66, and at this time the guide slider 62 will slide downward in the first slide groove 42, the spring member 63 will be compressed, and then the support rod 64 will drive the vibration protrusion 65 at the inner end to squeeze onto the upper surface of the filter screen 41 made of elastic material, and when the raised portion of the cam plate 61 is separated from the pushing and squeezing of the toggle post 66, the guide slider 62 will be on the spring member 63. The filter screen 41 is then detached from the upper surface of the filter screen 41 by the elastic restoring force of the guide slider 62, and the rapping protrusion 65 is detached from the upper surface of the filter screen 41. Then, as the guide slider 62 continuously slides up and down, the rapping protrusion 65 will continuously rap the filter screen 41 made of the elastic material, causing it to vibrate in the impurity collecting box 4, which can not only speed up the separation efficiency of impurities and sewage falling into the impurity collecting 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 continuously rotating, a power source can be continuously provided for the rapping of the filter screen 41, and there is no need to install a power source separately in the limited space to rap the filter screen 41. Moreover, the installation positions of the rapping protrusion 65 and the cam disc 61 will not affect the normal operation of the filter screen 41 and the conveying roller 21.

[0042] In the scheme designed by the present invention, the elastic rapping assembly 6 also includes an elastic membrane 67 and a blocking plate 68. The outer side surface sliding seal of the first slide groove 42 is provided with a segmented elastic membrane 67. 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. 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 arranged 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 conveying box 1, and will not interfere with the normally rotating cam plate 61.

[0043] In the scheme designed by the present invention, a lifting and waste discharge component 7 is arranged in the middle of the impurity collection box 4, and the lifting and waste discharge component 7 includes a first lifting block 71, a connecting pipe 72, a waste discharge pipe 73, an elastic sheet 74, a driving rod 75 and a slag discharge pipe 76. A second sliding groove 43 is vertically opened in the middle of the front and rear side walls of the impurity collection box 4, and a first lifting block 71 is slidably arranged in the second sliding groove 43. A connecting pipe 72 is fixed between the symmetrical first lifting blocks 71, and the corresponding ends of the segmented filter screen 41 are connected to the same connecting pipe 72. A guide cavity 721 is opened on the connecting pipe 72 along its length direction, and the symmetrical guide cavity 721 is symmetrically arranged in the middle of the front and rear side walls of the impurity collection box 4. The cavity 721 is located on the upper surface of the filter screen 41, and a waste discharge pipe 73 is rotatably inserted in the connecting pipe 72, and a symmetrical notch cavity 731 is also opened on the pipe wall of the waste discharge 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, and a driving rod 75 is horizontally fixed to the front end of the waste discharge pipe 73, and the driving rod 75 extends out of the front side of the conveying box 1. The tail of the waste discharge pipe 73 is connected to a slag discharge pipe 76, and one end of the slag discharge pipe 76 is located below between the symmetrical notch cavities 731, and the slag discharge pipe 76 is rotatably extended out of the rear side of the conveying box 1; the outside of the conveying box 1 is provided with a lifting drive assembly 8;

[0044] Specifically, when it is necessary to discharge the impurities collected on the filter screen 41, the lifting drive assembly 8 can be used to control the symmetrical first lifting block 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 part of the filter screen 41 on both sides to be symmetrically recessed through the connecting pipe 72, and then the lifting drive assembly 8 is controlled to work, so that it drives the waste discharge pipe 73 to rotate in the connecting pipe 72 through the driving rod 75, so that the symmetrically opened notch cavity 731 is aligned with the symmetrically opened guide cavity 721 on the connecting pipe 72, and then the impurities accumulated on the inclined filter screen 41 will be inclinedly guided through the connected guide cavity 721 and the notch cavity 731 into the waste discharge pipe 73, and then be sucked out through the slag discharge pipe 76. At the same time, when the impurities of the inclined filter screen 41 are discharged, the rotation of the cam plate 61 will vibrate the inclined filter screen 41 through the vibrating protrusion 65, so as to facilitate the acceleration of the cleaning of the filter screen 41. The impurities are quickly discharged and cleaned. When the impurities on the filter screen 41 are cleaned, 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 pipe 73 rotates in the opposite direction in the connecting pipe 72, so that the gap cavity 731 opened therein is disengaged from the diversion cavity 721, so that the pipe wall of the waste pipe 73 can block and seal the diversion cavity 721 opened on the connecting pipe 72, thereby preventing the impurities normally separated on the surface of the filter screen 41 from continuously entering the waste pipe 73; and when the filter screen 41 is in a horizontal state for normal filtering, the segmented filter screen 41 can be supported by gravity through the connecting pipe 72, thereby preventing the elastic material filter screen 41 from being laid as a whole in the impurity collection box 4, and the middle part of the filter screen 41 from settling due to excessive impurities accumulated on the surface, thereby affecting the normal separation of sewage and mixed impurities by the filter screen 41.

[0045] In the scheme 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 conveying box 1 are vertically provided with a third sliding groove 10, and the second lifting block 81 is slidably arranged in the third sliding groove 10. The outer end of the driving 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. A segmented sealing film 83 is slidably arranged at the outer notch of the second sliding groove 43, 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. A rotating disk 84 is rotatably installed in the second lifting block 81 slidingly arranged on the rear side wall of the conveying box 1 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 be lowered in the impurity collecting box 4, the piston rod of the lifting cylinder 82 will be retracted, so that it drives the second lifting block 81 to slide and descend in the third sliding groove 10, and the driving rod 75 will drive the first lifting block 71 to descend in 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 the sewage or impurities in the impurity collecting box 4 from passing through the second sliding groove 43. The gap will cause leakage; and when the servo motor on the second lifting block 81 is working, it will drive the waste discharge pipe 73 to rotate through the driving rod 75, so that the notch cavity 731 opened in it is aligned with the guide cavity 721, and 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 side through the rotating disk 84, so that the rotated slag discharge pipe 76 can always be located at the bottom of the waste discharge pipe 73, and the impurities accumulated inside it can be quickly discharged, and it will not affect the normal rotation of the slag discharge pipe 76 on the rear side wall of the conveying box 1.

[0047] In the scheme designed in the present invention, the upper box opening of the impurity collection box 4 is equidistantly mounted with a plurality of lifting rollers 44 along its length direction, and 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, to prevent the conveyor belt 2 from sinking due to the heavy weight of the wollastonite continuously transported on the conveyor belt 2, which would affect the normal transportation and processing of the wollastonite on the conveyor belt 2.

[0048] In the scheme designed by the present invention, a feed pipe 9 is connected to the top left side of the conveying box 1, and a discharge cavity 11 is opened on its right side wall, a guide baffle 91 is obliquely installed on the left inner wall of the conveying box 1, and the guide baffle 91 is located below the feed pipe 9, and a guide plate 92 is also obliquely installed on the inner wall of the cavity mouth of the discharge cavity 11, and the inner end of the guide plate 92 is in contact with the end face of the conveyor belt 2; specifically, the design of the feed pipe 9 is convenient for continuously conveying wollastonite to the conveying box 1, and the opening of the discharge cavity 11 can discharge the cleaned wollastonite from the conveying box 1, and the design of the guide baffle 91 can block the wollastonite falling into the conveying box 1 to prevent it from directly hitting the conveyor belt 2, and the guide plate 92 can safely and quickly guide the cleaned 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 conveying box 1 and the conveyor belt 2.
