Description

Technical Field

[0001] This utility model relates to the field of extraction devices, and more particularly to a stone extraction device. Background Technology

[0002] In the field of stone processing, before entering the subsequent deep processing steps, stone usually needs to undergo pre-treatment steps such as washing and dehydration to remove the mud, impurities and other substances attached to the surface of the stone, thereby ensuring the quality of the processed products.

[0003] Currently, most industries use intermittent immersion equipment to complete the washing of stone materials. When this type of equipment is working, a certain amount of stone materials need to be put into the immersion tank first, and the stone materials are washed by contacting water manually or by simple mechanical means. After the washing is completed, the machine needs to be stopped and the stone materials are taken out of the immersion tank. Then, new stone materials are put in for the next round of washing. During the loading and unloading and process changeover, the equipment is in a completely stopped state, resulting in a large amount of downtime waiting time, which seriously restricts the processing efficiency and processing volume of stone materials.

[0004] Meanwhile, the dewatering process of washed stones often relies on independent equipment, requiring manual transfer of the washed stones to the dewatering equipment. This not only increases labor costs and transfer time, but also makes it difficult to achieve a seamless connection between the washing and dewatering processes. This decentralized and intermittent processing mode has a low degree of automation, a cumbersome overall process, and high operating costs, which can no longer meet the modern stone processing industry's demand for efficient, continuous, and low-cost production. Utility Model Content

[0005] The purpose of this utility model is to provide a stone extraction device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stone extraction device, comprising an extraction component for extracting stone and a fixing frame at its bottom, wherein a dehydration component is provided at the bottom of the extraction component for dehydrating the stone after it has been soaked, and conveying components are installed on both sides of the extraction component for conveying the soaked stone to the dehydration component, wherein the conveying component and the dehydration component are driven by a transmission component. The extraction assembly includes a water tank and an internal immersion tank. A push plate is slidably installed inside the immersion tank. An electric cylinder is installed at the lower part of the push plate. The output shaft of the electric cylinder drives the push plate to reciprocate. The conveying assembly includes two conveying seats symmetrically installed inside the water tank on both sides of the immersion tank, and a connecting box installed in the water tank and connected to the two conveying seats. Conveying blades for conveying materials are rotatably provided on the inner sides of the two conveying seats respectively. The dehydration assembly includes a fixed base connected to the connecting box, with a conveying port extending through the center of the fixed base, and a filter cylinder rotatably mounted inside the conveying port.

[0007] As a further description of the above technical solution: the water tank is connected to the immersion tank, and a sealed box is fixedly connected between the bottom middle of the immersion tank and the bottom middle of the inner cavity of the water tank, and the electric cylinder is installed in the sealed box.

[0008] As a further description of the above technical solution: the push plate is sloping with a narrow top and a wide bottom, and several drainage slits are equidistantly opened along its inclined surface. Several support frames are symmetrically installed equidistantly on the inner side of the water tank to support the two conveying seats and the immersion tank.

[0009] As a further description of the above technical solution: each of the two conveyor seats has a material trough at its top end that communicates with the connecting box, and each of the two material troughs has an installation hole at its bottom end, and a conveyor blade is rotatably installed in each of the two installation holes.

[0010] As a further description of the above technical solution: a semi-circular guide hopper is rotatably installed at one end of the filter cylinder near the discharge port of the connecting box and fixed to the inner surface of the conveying port; a second conveying blade is coaxially fixedly connected to the inner side of the filter cylinder; and several interconnected water collection troughs are equidistantly opened on the inner surface of the fixed seat.

[0011] As a further description of the above technical solution: the transmission assembly includes a servo motor fixedly mounted on the fixed base, and two single-groove pulleys respectively mounted on the rotating shafts of the two conveyor blades. The output shaft of the servo motor is fixedly connected to the rotating shaft of the second conveyor blade, and a double-groove pulley that is connected to the two single-groove pulleys is mounted on the outer surface of the output shaft of the servo motor.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The push plate inside the immersion tank is pushed back and forth by an electric cylinder, so that the stone material in the immersion tank can fully contact the water for rinsing. After the stone material is rinsed, the push plate is pushed to the upper port of the immersion tank by the electric cylinder again. In this way, the stone material slides down the inclined surface of the push plate into the conveying assembly for the next process. New stone material can be added to the immersion tank for the next round of rinsing. In this way, the stone material can be rinsed without interruption, which completely eliminates the downtime waiting time during loading, unloading and process switching of traditional intermittent immersion equipment, and enables the equipment to operate continuously, which greatly improves the stone material processing capacity. The washed stone is conveyed into the filter cylinder by the conveying component. The high-speed rotation of the filter cylinder dehydrates the washed stone. Together with the extraction component, it forms a complete and highly automated stone pretreatment continuous production line that combines washing and dewatering. This completely overturns the traditional intermittent processing mode, significantly improves processing capacity and reduces operating costs. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 - Figure 2 As shown, the present invention provides a stone extraction device, including an extraction component 2 for extracting stone and a fixing frame 1 at its bottom end. The bottom of the extraction component 2 is provided with a dehydration component 4 for dehydrating the stone after it has been soaked. The extraction component 2 is provided with conveying components 3 on both sides for conveying the soaked stone to the dehydration component 4. The conveying component 3 and the dehydration component 4 are driven by a transmission component 5. In actual operation, this device first periodically lifts the stone raw material through the extraction component 2, repeatedly immersing and exposing it in the extraction solution. This dynamic reciprocating motion forces the solution to be renewed on the surface and between the cracks of the stone, achieving efficient and uniform wetting. After wetting is completed, the extraction component 2 lifts the stone to a fixed discharge position, and the wet stone is directly and continuously fed into the dewatering component 4 of the high-speed centrifugal dewatering device through the conveying component 3. With the help of the powerful centrifugal force generated by high-speed rotation, a large amount of residual extraction liquid and water between the stone particles and on the surface are quickly removed, completing the deep dewatering treatment. The dewatered stone is discharged for subsequent processes, thus realizing continuous and automated operation from wetting to dewatering, significantly improving efficiency and reducing the time spent in intermediate links.

[0017] Specifically, such as Figure 3 As shown, the extraction assembly 2 includes a water tank 21 and an internal immersion tank 22. A push plate 24 is slidably installed inside the immersion tank 22. An electric cylinder 25 is installed at the lower part of the push plate 24. The output shaft of the electric cylinder 25 drives the push plate 24 to reciprocate. Water tank 21 is connected to immersion tank 22. A sealing box 23 is fixedly connected between the bottom middle of immersion tank 22 and the bottom middle of the inner cavity of water tank 21. Electric cylinder 25 is installed in sealing box 23. The push plate 24 is sloping with a narrow top and a wide bottom, and several drainage slits 241 are equidistantly opened along its inclined surface. Several support frames 26 are equidistantly and symmetrically installed on the inner side of the water tank 21 to support the two conveying seats 31 and the immersion tank 22. The stone raw material is quantitatively transported into the impregnation tank 22 by the conveyor. The push plate 24 in the impregnation tank 22 is pushed back and forth by the electric cylinder 25. In this way, the stone raw material is repeatedly immersed and exposed in the leachate. This dynamic reciprocating motion is used to force the renewal of the solution on the surface of the stone and between the cracks, so as to achieve efficient and uniform impregnation. After the stone is washed, the push plate 24 is pushed to the upper port of the soaking tank 22 by the electric cylinder 25. In this way, the stone slides down the inclined surface of the push plate 24 into the conveying assembly 3 for the next process. When pushing the stone raw material upward, the leaching liquid on the push plate 24 flows back into the soaking tank 22 through the drain gap 241. The support frame 26 supports the conveyor seat 31 and the immersion tank 22 to prevent the immersion tank 22 and the conveyor seat 31 from shaking due to unnecessary resonance caused by the sloshing of the immersion liquid during the reciprocating lifting process.

[0018] Furthermore, such as Figure 4 As shown, the conveying assembly 3 includes two conveying seats 31 symmetrically installed in the water tank 21 on both sides of the immersion tank 22, and a connecting box 32 installed in the water tank 21 and connected to the two conveying seats 31. Conveying blades 313 for conveying materials are rotatably provided on the inner side of the two conveying seats 31 respectively. Both conveyor seats 31 have material troughs 311 at their top ends that communicate with the connecting box 32. Both material troughs 311 have mounting holes 312 at their bottom ends. Both mounting holes 312 have conveyor blades 313 rotatably installed inside them. After the stone material has been soaked, it falls into the trough 311 through the inclined surface of the push plate 24. Driven by the transmission component 5, the conveying blade 313 in the mounting hole 312 rotates, thereby conveying the stone material in the trough 311 to the connecting box 32, and then falling into the conveying port 42 through the discharge port of the connecting box 32 for dewatering.

[0019] Furthermore, such as Figure 5 As shown, the dehydration assembly 4 includes a fixed base 41 connected to the connecting box 32. A conveying port 42 is provided through the center of the fixed base 41, and a filter cylinder 43 is rotatably installed inside the conveying port 42. A semi-circular guide hopper 431, which is fixed to the inner surface of the conveying port 42, is rotatably installed at one end of the filter cylinder 43 near the discharge port of the connecting box 32. A conveying blade 432 is coaxially fixedly connected to the inner side of the filter cylinder 43. Several interconnected water collection troughs 45 are equidistantly opened on the inner surface of the fixed seat 41. After the stone falls into the conveying port 42, it enters the filter cylinder 43 through the semi-circular guide hopper 431. The filter cylinder 43 is driven to rotate by the transmission component 5. With the help of the strong centrifugal force generated by the high-speed rotation of the filter cylinder 43, a large amount of leachate residue and water between the stone particles and on the surface are quickly removed, and the deep dewatering treatment is completed. When the filter cylinder 43 rotates, it drives the second conveyor blade 432 to rotate together and transport the stone from the conveying port 42 to the outside. As the filter cylinder 43 rotates at high speed, the moisture on the outer surface of the stone passes through the filter holes of the filter cylinder 43 due to centrifugal force and collects in the water collection trough 45 opened inside the conveying port 42.

[0020] Furthermore, such as Figure 5 As shown, the transmission assembly 5 includes a servo motor 51 fixedly mounted on the fixed base 41, and two single-groove pulleys 53 respectively mounted on the rotating shafts of the two conveyor blades 313. The output shaft of the servo motor 51 is fixedly connected to the rotating shaft of the second conveyor blade 432, and a double-groove pulley 52 that is connected to the two single-groove pulleys 53 is mounted on the outer surface of the output shaft of the servo motor 51. Start the servo motor 51. The output shaft of the servo motor 51 drives the rotating shaft of the semi-circular guide hopper 431, which in turn drives the filter cylinder 43 to rotate together. The double groove pulley 52 on the output shaft of the servo motor 51 drives the single groove pulley 53 on the rotating shaft of the two conveyor blades 313 to rotate together.

[0021] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
