Description

Technical Field

[0001] The present application belongs to the technical field of high-purity quartz sand preparation, and specifically relates to a fully automatic flotation quantitative conveying device for quartz sand. Background Art

[0002] Quartz sand is quartz particles made by crushing quartz stone. It is a hard, wear-resistant, and chemically stable silicate mineral. The production process of quartz sand is as follows: after crushing the quartz stone, it is processed into quartz sand particles of corresponding specifications according to customer requirements, and then the processed quartz sand particles are subjected to flotation, water washing, acid washing, deacidification water washing, dehydration, drying, cooling, screening, and magnetic separation in sequence.

[0003] At present, when flotation of quartz sand, it is necessary to first use a hoist to lift the quartz sand, and then use a conveyor belt to transport the quartz sand to the flotation tank; in order to improve the flotation efficiency of quartz sand, multiple flotation tanks are usually set up in the factory, and because the discharge port of the hoist is relatively fixed, the hoist can only transport quartz sand for one conveyor belt, so it is necessary to set up multiple hoists to provide quartz sand for multiple conveyor belts, thereby increasing the production cost of quartz sand and the area occupied by quartz sand flotation. In addition, when conveying quartz sand to the flotation tank, it is usually based on the real-time observation of the flotation tank by the staff to determine the amount of quartz sand delivered to the flotation tank, which results in a waste of labor, and the amount of quartz sand entering the flotation tank each time is different, which makes the quality of quartz sand produced each time different. Utility Model Content

[0004] The present application provides a fully automatic flotation quantitative conveying device for quartz sand, so as to reduce the production cost of quartz sand, reduce the area occupied by the equipment for conveying quartz sand to the flotation tank, and reduce the number of workers required when flotating quartz sand, while increasing the quality stability of quartz sand.

[0005] The technical solution adopted in this application is:

[0006] A fully automatic flotation quantitative conveying device for quartz sand comprises an elevator, a first conveyor belt and a second conveyor belt, wherein the elevator is used to convey quartz sand for the first conveyor belt, and the first conveyor belt has a conveying end located above the second conveyor belt, so that when the first conveyor belt rotates in a first direction, the first conveyor belt quantitatively conveys quartz sand to the second conveyor belt, and when the first conveyor belt rotates in a second direction, the first conveyor belt quantitatively conveys quartz sand to a first flotation tank; when the second conveyor belt rotates in the first direction and the first conveyor belt rotates in the first direction, the second conveyor belt conveys quartz sand to a second flotation tank, and when the second conveyor belt rotates in the second direction, the second conveyor belt conveys quartz sand to a third flotation tank.

[0007] By adopting the above technical scheme, when the quartz sand fully automatic flotation quantitative conveying device of the present application is used to feed the flotation tank, the elevator conveys the quartz sand to the first conveyor belt, and the first conveyor belt rotates along the second direction so that the quartz sand is conveyed to the first flotation tank. When the amount of quartz sand conveyed by the first conveyor belt to the first flotation tank reaches a set value, the first conveyor belt rotates along the first direction, and then the quartz sand falls to the second conveyor belt, and then the second conveyor belt rotates along the first direction so that the quartz sand enters the second flotation tank. When the conveying amount of the first conveyor belt to the second conveyor belt reaches a set value, the second conveyor belt rotates along the second direction so that the first conveyor belt continues to convey the quartz sand conveyed by the second conveyor belt to the third flotation tank. In this process, the elevator and the first conveyor belt do not need to be stopped, so as to improve the conveying efficiency of the quartz sand.

[0008] The fully automatic flotation quantitative conveying device for quartz sand in the present application realizes the conveying of quartz sand to different flotation tanks through the cooperation of the first conveyor belt and the second conveyor belt, so that the fully automatic flotation quantitative conveying device for quartz sand in the present application only needs to set up one hoist, so as to reduce the conveying cost of quartz sand and reduce the area occupied by the equipment for conveying quartz sand. In addition, the fully automatic flotation quantitative conveying device for quartz sand in the present application realizes the quantitative conveying of quartz sand, so as to avoid the need for staff to observe the flotation tank in real time when conveying quartz sand, thereby reducing the number of staff required to reduce the production cost of quartz sand. In addition, it avoids the situation that quartz sand overflows from the flotation tank due to the negligence of the staff, thereby causing the factory environment to be polluted. In addition, the amount of quartz sand entering the flotation tank each time is the same, so as to ensure the quality stability of quartz sand and improve the customer experience. In addition, it also avoids the situation that quartz sand falls into the factory and causes the factory environment to be polluted.

[0009] Optionally, multiple first conveyor belts are arranged in sequence between the second conveyor belt and the elevator, each of the first conveyor belts has a material receiving end, and the conveying end of the first conveyor belt close to the elevator of two adjacent first conveyor belts is located above the material receiving end of the other first conveyor belt.

[0010] By adopting the above technical solution, that is, the quartz sand fully automatic flotation quantitative conveying device in the present application can convey quartz sand to multiple No. 1 flotation tanks, so as to improve the production efficiency of quartz sand, reduce the cost of the quartz sand fully automatic flotation quantitative conveying device and improve the utilization rate of the elevator.

[0011] Optionally, each of the first conveyor belts is arranged to be inclined upward along the direction from the material receiving end to the conveying end.

[0012] By adopting the above technical solution, since each first conveyor belt is arranged to be inclined upward from the direction from the receiving end to the conveying end, so that the No. 1 flotation tank, the No. 2 flotation tank and the No. 3 flotation tank are kept at the same height, the quartz sand drop position can maintain the same distance from the position of the flotation tank mouth; at the same time, it can avoid the situation where the vertical height of the quartz sand fully-automatic flotation quantitative conveying device increases due to the provision of multiple first conveyor belts, so as to reduce the height of the quartz sand fully-automatic flotation quantitative conveying device.

[0013] Optionally, it further comprises a hopper scale arranged at the discharge port of the elevator, so that the quartz sand transported by the elevator enters the hopper scale for weighing and then falls onto the first conveyor belt;

[0014] Or, the first conveyor belt is a belt scale.

[0015] By adopting the above technical solution, when conveying quartz sand, the elevator conveys the quartz sand to the hopper scale, so that the hopper scale weighs the quartz sand, so as to realize quantitative conveying of quartz sand by the first conveyor belt, thereby avoiding the need for staff to observe the flotation tank in real time.

[0016] The quartz sand transported by the elevator falls onto the first conveyor belt. Since the first conveyor belt is a belt scale, the first conveyor belt weighs the quartz sand so that the first conveyor belt can transport the quartz sand quantitatively. No staff operation is required in this process to realize automatic transportation of quartz sand for the flotation tank.

[0017] Optionally, both sides of the top of the first conveyor belt and the second conveyor belt are provided with blocking members that abut against the belt body, and a feeding space is formed between the two blocking members.

[0018] By adopting the above technical solution, when quartz sand falls onto the belt body of the first conveyor belt or the second conveyor belt, the belt body has a certain deformation ability, which may cause the quartz sand to jump. At this time, the blocking member can block the quartz sand so that the quartz sand stays in the feeding space to avoid the quartz sand falling from the belt body and causing waste. In addition, after the blocking member blocks the quartz sand, it can also prevent the quartz sand from falling through the gap between the belt body and the frame, thereby reducing the production cost of quartz sand and ensuring the cleanliness of the factory.

[0019] Optionally, the blocking member includes a connecting plate and a flexible plate arranged at the bottom of the connecting plate, and the flexible plate is in contact with the belt body.

[0020] By adopting the above technical solution, since the flexible plate contacts the belt body, the belt body is prevented from being damaged by the hard blocking member, thereby increasing the service life of the belt body, reducing the service life of the fully automatic flotation and quantitative conveying device for quartz sand, and reducing the failure rate of the fully automatic flotation and quantitative conveying device for quartz sand. At the same time, the setting of the flexible plate can also reduce the sound generated when quartz sand falls onto the belt body, thereby reducing the noise in the factory and improving the working comfort of the staff.

[0021] Optionally, the flexible plate has a connecting end connected to the connecting plate and a contacting end contacting the belt body, the contacting end is located on the inner side of the connecting end and the flexible plate undergoes elastic deformation.

[0022] By adopting the above technical solution, as the use time of the conveyor belt continues to increase, the flexible plate will be worn out. Since the abutting end is located on the inner side of the connecting end and the flexible plate undergoes elastic deformation, the flexible plate can adjust itself under the action of its own elasticity after being worn out, so that the flexible plate and the belt body remain in a state of abutment, thereby avoiding the need for manual adjustment of the flexible plate. In addition, the elastic deformation of the flexible plate when it abuts against the belt body can also increase the contact effect between the flexible plate and the belt body, so as to further avoid the situation where quartz sand falls through the gap between the flexible plate and the belt body.

[0023] Optionally, the flexible plate is located outside the connecting plate, and a fixing plate is provided on a side of the flexible plate facing away from the connecting plate, and the fixing plate is fixedly connected to the connecting plate by a fastener to squeeze and fix the flexible plate.

[0024] By adopting the above technical solution, since the flexible plate is located on the outside of the connecting plate, the situation where quartz sand accumulates on the top of the flexible plate is avoided, so that all the quartz sand that falls onto the belt body enters the flotation tank, and the flexible plate is fixed by the fixing plate and the connecting plate squeezing the flexible plate, so as to increase the connection stability between the flexible plate and the connecting plate.

[0025] Optionally, the fixing plate has an extension section extending to the bottom of the connecting plate, and the extension section is bent toward the inner side of the connecting plate to apply pressure to the flexible plate toward the inner side of the connecting plate.

[0026] By adopting the above technical solution, since the extension section is bent toward the inside of the connecting plate, the extension section can apply pressure toward the inside of the connecting plate to the flexible plate to bend the flexible plate, while increasing the connection stability between the flexible plate and the connecting plate.

[0027] Optionally, a dustproof plate is provided on the top of the two blocking members, and the dustproof plate has a feed port.

[0028] By adopting the above technical solution, the quartz sand falls into the belt body through the feed port, and the dustproof plate can block the quartz sand powder in the quartz sand to prevent the quartz sand powder from flying in the factory, thereby ensuring the cleanliness of the factory and preventing the quartz sand powder from causing harm to the workers. In addition, the dustproof plate can also block the dust to prevent the dust in the factory from falling on the quartz sand and polluting the quartz sand, thereby ensuring the quality of the quartz sand.

[0029] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0030] 1. The fully automatic flotation quantitative conveying device of quartz sand in the present application comprises a hoist, a first conveyor belt and a second conveyor belt, the hoist is used to convey quartz sand for the first conveyor belt, the first conveyor belt has a conveying end located above the second conveyor belt, so that when the first conveyor belt rotates along the first direction, the first conveyor belt quantitatively conveys quartz sand to the second conveyor belt, and when the first conveyor belt rotates along the second direction, the first conveyor belt quantitatively conveys quartz sand to the first flotation tank; when the second conveyor belt rotates along the first direction and the first conveyor belt rotates along the first direction, the second conveyor belt conveys quartz sand to the second flotation tank, and when the second conveyor belt rotates along the second direction, the second conveyor belt conveys quartz sand to the third flotation tank, thereby realizing the conveying of quartz sand to different flotation tanks, so that the fully automatic flotation quantitative conveying device of quartz sand in the present application only needs to set one hoist, thereby reducing the conveying cost of quartz sand and reducing the area occupied by the equipment for conveying quartz sand. In addition, the fully automatic flotation quantitative conveying device for quartz sand in the present application realizes the quantitative conveying of quartz sand, so as to avoid the need for workers to observe the situation of the flotation tank in real time when conveying quartz sand, thereby reducing the number of workers required and reducing the production cost of quartz sand.

[0045] Reference Figures 1 to 4, discloses a fully automatic flotation quantitative conveying device for quartz sand, comprising an elevator 1, a first conveyor belt 2 and a second conveyor belt 3, wherein the elevator 1 is used to convey quartz sand for the first conveyor belt 2, and the first conveyor belt 2 has a conveying end located above the second conveyor belt 3, so that when the first conveyor belt 2 rotates along a first direction, the first conveyor belt 2 quantitatively conveys quartz sand to the second conveyor belt 3, and when the first conveyor belt 2 rotates along a second direction, the first conveyor belt 2 quantitatively conveys quartz sand to a first flotation tank; when the second conveyor belt 3 rotates along the first direction and the first conveyor belt 2 rotates along the first direction, the second conveyor belt 3 conveys quartz sand to a second flotation tank, and when the second conveyor belt 3 rotates along the second direction, the second conveyor belt 3 conveys quartz sand to a third flotation tank.

[0046] When the fully automatic flotation quantitative conveying device for quartz sand in the present application is used to feed the flotation tank, the hoist 1 conveys the quartz sand to the first conveyor belt 2, and the first conveyor belt 2 rotates along the second direction so that the quartz sand is conveyed to the first flotation tank. When the amount of quartz sand conveyed by the first conveyor belt 2 to the first flotation tank reaches a set value, the first conveyor belt 2 rotates along the first direction, and then the quartz sand falls to the second conveyor belt 3, and then the second conveyor belt 3 rotates along the first direction so that the quartz sand enters the second flotation tank. When the conveying amount of the first conveyor belt 2 to the second conveyor belt 3 reaches a set value, the second conveyor belt 3 rotates along the second direction so that the first conveyor belt 2 continues to convey the quartz sand conveyed by the second conveyor belt 3 to the third flotation tank. In this process, the hoist 1 and the first conveyor belt 2 do not need to be stopped to achieve continuous feeding to the flotation tank, thereby improving the conveying efficiency of the quartz sand.

[0047] The fully automatic flotation quantitative conveying device for quartz sand in the present application realizes the conveying of quartz sand to different flotation tanks through the cooperation of the first conveyor belt 2 and the second conveyor belt 3, so that the fully automatic flotation quantitative conveying device for quartz sand in the present application only needs to set up one elevator 1, so as to reduce the conveying cost of quartz sand and reduce the area occupied by the equipment for conveying quartz sand. In addition, the fully automatic flotation quantitative conveying device for quartz sand in the present application realizes the quantitative conveying of quartz sand, so as to avoid the need for staff to observe the situation of the flotation tank in real time when conveying quartz sand, thereby reducing the number of staff required to reduce the production cost of quartz sand. At the same time, the amount of quartz sand entering the flotation tank each time is the same to ensure the quality stability of quartz sand. In addition, it also avoids the situation where quartz sand falls into the factory building and causes the factory building environment to be polluted.

[0048] It can be understood that the above-mentioned first conveyor belt 2 and second conveyor belt rotating along the first direction and the second conveyor belt 3 rotating along the second direction can be simply understood as the forward and reverse rotation of the conveyor belts.

[0049] The present application does not specifically limit the number of the first conveyor belts 2. Preferably, refer to Figure 1 , a plurality of first conveyor belts 2 are sequentially arranged between the second conveyor belt 3 and the elevator 1, each of the first conveyor belts 2 has a material receiving end, and the conveying end of the first conveyor belt 2 close to the elevator 1 of two adjacent first conveyor belts 2 is located above the material receiving end of the other first conveyor belt 2. In other words, the quartz sand fully automatic flotation quantitative conveying device in the present application can convey quartz sand to multiple No. 1 flotation tanks, that is, a No. 1 flotation tank can be arranged at the bottom of the material receiving end of each first conveyor belt 2, so as to improve the production efficiency of quartz sand, reduce the cost of the quartz sand fully automatic flotation quantitative conveying device and improve the utilization rate of the elevator 1.

[0050] Further, see Figure 1 Each first conveyor belt 2 is arranged to be inclined upward in the direction from the receiving end to the conveying end, so that the No. 1 flotation tank, the No. 2 flotation tank and the No. 3 flotation tank are kept at the same height, and the quartz sand drop position can maintain the same distance from the position of the flotation tank mouth; at the same time, it can avoid the situation where the vertical height of the quartz sand fully-automatic flotation quantitative conveying device increases due to the provision of multiple first conveyor belts 2, so as to reduce the height of the quartz sand fully-automatic flotation quantitative conveying device.

[0051] In other embodiments, only one first conveyor belt 2 may be provided, so that the fully automatic flotation quantitative conveying device for quartz sand in the present application can only convey quartz sand for a No. 1 flotation tank, a No. 2 flotation tank and a No. 3 flotation tank.

[0052] The present application does not specifically limit the manner in which the first conveyor belt 2 quantitatively conveys the quartz sand, and it may adopt any one of the following embodiments:

[0053] Embodiment 1. In this embodiment, referring to Figure 1 The quartz sand automatic flotation quantitative conveying device also includes a hopper scale 6 arranged at the discharge port of the elevator 1, so that the quartz sand conveyed by the elevator 1 enters the hopper scale 6 for weighing and then falls to the first conveyor belt 2; that is, when conveying the quartz sand, the elevator 1 conveys the quartz sand to the hopper scale 6, so that the hopper scale 6 weighs the quartz sand, so as to realize the quantitative conveying of the quartz sand by the first conveyor belt 2, so as to avoid the need for staff to observe the flotation tank in real time.

[0054] Embodiment 2. In this embodiment, the first conveyor belt 2 is a belt scale, that is, the quartz sand transported by the elevator 1 falls onto the first conveyor belt 2. Since the first conveyor belt 2 is a belt scale, the first conveyor belt 2 weighs the quartz sand so that the first conveyor belt 2 can perform quantitative transportation. During this process, no staff operation is required to realize automatic transportation of quartz sand to the flotation tank.

[0055] It should be noted that the first conveyor belt 2 has a belt body 22 and a frame 21 .

[0056] When the quartz sand is transported, since the belt body 22 of the first conveyor belt 2 has a certain deformation ability, the quartz sand will jump when it falls on the belt body 22, so that the quartz sand may be separated from the belt body 22, and there is a certain gap between the belt body 22 and the frame 21, and the quartz sand may also fall from the gap between the belt body 22 and the frame 21.

[0057] In a preferred embodiment, referring to Figure 2 , Figure 3 and Figure 4 Both sides of the top of the first conveyor belt 2 and the second conveyor belt 3 are provided with blocking members 4 that abut against the belt body 22, and a feeding space is formed between the two blocking members 4, so that when the quartz sand falls onto the belt body 22 of the first conveyor belt 2 or the second conveyor belt 3, the blocking member 4 can block the quartz sand so that the quartz sand stays in the feeding space to avoid the quartz sand falling from the belt body 22 and causing waste. In addition, after the blocking member 4 blocks the quartz sand, it can also prevent the quartz sand from falling through the gap between the belt body 22 and the frame 21, thereby reducing the production cost of the quartz sand and ensuring the cleanliness of the factory.

[0058] The present application does not specifically limit the structure of the blocking member 4. Preferably, refer to Figure 2 , Figure 3 and Figure 4 The blocking member 4 includes a connecting plate 41 and a flexible plate 42 disposed at the bottom of the connecting plate 41. The flexible plate 42 contacts the belt body 22, thereby avoiding the situation where the blocking member 4 is hard and causes damage to the belt body 22, thereby increasing the service life of the belt body 22, thereby reducing the service life of the fully automatic flotation and quantitative conveying device for quartz sand, and reducing the failure rate of the fully automatic flotation and quantitative conveying device for quartz sand. At the same time, the setting of the flexible plate 42 can also reduce the sound generated when the quartz sand falls onto the belt body 22, thereby reducing the noise in the factory and improving the working comfort of the staff.

[0059] Specifically, support rods 211 are provided on the tops of the frames 21 of the first conveyor belt 2 and the second conveyor belt 3, and the tops of the connecting plates 41 are connected to the support rods 211 to increase the height that the blocking member 4 can block, so as to further prevent quartz sand from falling from the belt body 22, and the top end of the connecting plate 41 is C-shaped, so that the top end of the connecting plate 41 can be wrapped around the outside of the top of the support rod 211, so as to increase the connection stability between the connecting plate 41 and the support rod 211.

[0060] Further, see Figure 2 , Figure 3 and Figure 4 The flexible plate 42 has a connecting end connected to the connecting plate 41 and a contacting end contacting the belt body 22 , the contacting end is located on the inner side of the connecting end and the flexible plate 42 undergoes elastic deformation.

[0061] As the conveyor belt is used for a longer time, the flexible plate 42 will wear out. Since the contact end is located on the inner side of the connection end and the flexible plate 42 undergoes elastic deformation, the flexible plate 42 can adjust itself under the action of its own elasticity after being worn, so that the flexible plate 42 and the belt body 22 remain in a state of contact, thereby avoiding the need for manual adjustment of the flexible plate 42. In addition, the elastic deformation of the flexible plate 42 when it contacts the belt body 22 can also increase the contact effect between the flexible plate 42 and the belt body 22, so as to further prevent the quartz sand from falling through the gap between the flexible plate 42 and the belt body 22.

[0062] Further, refer to Figure 3 and Figure 4 One end of the bottom of the connecting plate 41 is bent toward the inner side of the inner body so that the connecting plate 41 can guide the quartz sand, thereby gathering the quartz sand in the middle position in the width direction of the belt body 22.

[0063] The present application does not specifically limit the material of the flexible plate 42. Preferably, the flexible plate 42 is made of rubber material to increase the elastic deformation effect of the flexible plate 42. In other embodiments, the flexible plate 42 may also be made of other elastic non-metallic materials.

[0064] The present application does not specifically limit the connection method between the flexible board 42 and the connecting board 41. Preferably, refer to Figure 3 and Figure 4 The flexible plate 42 is located outside the connecting plate 41 , and a fixing plate 411 is provided on the side of the flexible plate 42 facing away from the connecting plate 41 . The fixing plate 411 is fixedly connected to the connecting plate 41 by fasteners to squeeze and fix the flexible plate 42 .

[0065] Since the flexible plate 42 is located on the outside of the connecting plate 41, the situation where quartz sand accumulates on the top of the flexible plate 42 is avoided, so that all the quartz sand that falls onto the belt body 22 enters the flotation tank, and the flexible plate 42 is fixed by squeezing the flexible plate 42 by the fixing plate 411 and the connecting plate 41, so as to increase the connection stability between the flexible plate 42 and the connecting plate 41.

[0066] Better, refer to Figure 3 and Figure 4The fixing plate 411 has an extension section 412 extending to the bottom of the connecting plate 41. The extension section 412 is bent toward the inner side of the connecting plate 41 to apply pressure toward the inner side of the connecting plate 41 to the flexible plate 42, so that the extension section 412 can apply pressure toward the inner side of the connecting plate 41 to the flexible plate 42 to bend the flexible plate 42, while increasing the connection stability between the flexible plate 42 and the connecting plate 41.

[0067] The application does not specifically limit the structure of the fastener. Preferably, the fastener is a pair of bolts penetrating the connecting plate 41, the flexible plate 42 and the fixing plate 411 to increase the connection stability between the flexible plate 42 and the connecting plate 41. In other implementation examples, the fastener may also be a screw.

[0068] In other embodiments, the flexible plate 42 may also be directly fixedly connected to the connecting plate 41 by screws.

[0069] It should be noted that the inner side of the connecting plate 41 mentioned above refers to the side of the connecting plate 41 facing the middle position in the width direction of the belt body 22, and the outer side of the connecting plate 41 refers to the side of the connecting plate 41 away from the middle position in the width direction of the belt body 22.

[0070] In other embodiments, reference Figure 3 and Figure 4 The blocking member 4 may also only include the connecting plate 41 , that is, the bottom of the connecting plate 41 directly contacts the belt body 22 .

[0071] In a preferred embodiment, referring to Figure 3 and Figure 4 , the tops of the two blocking members 4 are provided with dustproof plates 5, and the dustproof plates 5 have a feed port, that is, the tops of the connecting plates 41 are provided with dustproof plates 5, so that the tops of the first conveyor belt 2 and the second conveyor belt form a relatively closed conveying space, so as to block the quartz sand powder in the quartz sand, and prevent the quartz sand powder from flying in the factory, thereby ensuring the cleanliness of the factory, and preventing the quartz sand powder from causing harm to the staff. In addition, the dustproof plates can also block dust, so as to prevent the dust in the factory from falling on the quartz sand and polluting the quartz sand, so as to ensure the quality of the quartz sand.

[0072] Specifically, the feed port on the dustproof plate 5 corresponding to the first conveyor belt 2 is located at the material receiving end, so that quartz sand can enter the conveying space through the feed port, and the feed port on the dustproof plate 5 corresponding to the second conveyor belt 3 is located below the conveying end of the first conveyor belt 2, so that the quartz sand can fall onto the second conveyor belt 3 when the first conveyor belt 2 rotates along the first direction.

[0075] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
