Description

Technical Field

[0001] This invention belongs to the field of mineral exploration technology, specifically relating to a containerized automatic sampling system. Background Technology

[0002] When mining ore, it is common practice to first sample and investigate the ore to ensure the quality of the extracted material. Generally, ore sampling and investigation typically includes the following steps: crushing, screening, and testing.

[0003] The above steps all involve processing the ore using corresponding equipment. During the ore sampling and exploration process, the testing personnel usually send the ore to a crushing device for crushing, then send the crushed ore to a sizing machine for screening, and finally send the screened ore to a testing device for testing.

[0004] In the above steps, after each process is completed, the ore needs to be transported by the testing personnel to the designated location using transportation equipment for the next process. This increases the overall time for ore sampling and exploration and reduces the efficiency of ore sampling and exploration.

[0005] It is easy to imagine that the equipment required for ore exploration should be arranged in the order of ore sampling and exploration procedures, thereby saving the steps of transporting ore between adjacent procedures by the testing personnel and reducing the overall time of ore sampling and exploration.

[0006] However, with the distance between the crushing device and the detection device becoming closer, the crushing device emits a large amount of dust during the crushing process of the ore. This dust can easily accumulate at the detection device, reducing the detection accuracy of the device. Summary of the Invention

[0007] To address the challenge of effectively isolating the dust generated during the crushing process from affecting the accuracy of the testing devices while arranging the crushing, screening, and testing equipment for ore sampling and exploration in a compact, sequential manner to improve efficiency, this invention provides a containerized automatic sampling system.

[0008] The objective of this invention can be achieved through the following technical solutions: A containerized automatic sampling system includes, along the ore conveying direction, a crushing assembly, a reducing assembly, and a testing assembly connected in sequence. It also includes interconnected and hollow crushing containers, reducing containers, and testing containers, each corresponding to and matched with one of the crushing, reducing, or testing assemblies, with each assembly housed within its corresponding container. The crushing container has a crushing output port and a crushing input port. The crushing assembly includes a crushing input end, a crushing device, and a crushing output end connected in sequence. The crushing device is housed within the crushing container. The cross-sectional shape of the crushing input end matches the cross-sectional shape of the crushing input port, and their connection is sealed. The cross-sectional shape of the crushing output end matches the cross-sectional shape of the crushing output port, and their connection is also sealed.

[0009] As a preferred embodiment of the present invention, a dust collection device is also included, which includes a dust collection pump, a dust collection pipe and a dust collection box. The dust collection box is disposed outside the crushed container. The two ends of the dust collection pipe are respectively connected to the crushed container and the dust collection box. The dust collection pump is disposed on the dust collection box.

[0010] As a preferred embodiment of the present invention, the shrinking assembly includes a shrinking input end, a shrinking device, and a shrinking output end connected in sequence. The shrinking device is disposed inside the shrinking container. The shrinking input end is interconnected with the crushing output end, and the shrinking output end is interconnected with the detection assembly. The shrinking container is provided with a shrinking input port and a shrinking output port. The cross-sectional shape of the shrinking input end matches the cross-sectional shape of the shrinking input port, and the connection between the two is sealed. The cross-sectional shape of the shrinking output end matches the cross-sectional shape of the shrinking output port, and the connection between the two is sealed.

[0011] As a preferred embodiment of the present invention, it further includes a conveying device, which includes a conveyor belt disposed between the split container and the inspection container. The inspection container is provided with an inspection input port, and the end of the conveyor belt is connected to the inspection input port. The height of the beginning of the conveyor belt is lower than the setting height of the split output port.

[0012] As a preferred embodiment of the present invention, the distance between the conveyor belt and the reduced output port is less than 1 cm.

[0013] As a preferred embodiment of the present invention, it further includes an internally hollow conveyor container, the two ends of which are respectively fitted to the split container and the inspection container, and the conveyor belt is disposed inside the conveyor container.

[0014] As a preferred embodiment of the present invention, it further includes an absorption device, which includes an absorption pump, an absorption pipe, and an absorption box. The absorption box is disposed outside the conveying container. The two ends of the absorption pipe are respectively connected to the conveying container and the absorption box. The absorption pump is disposed on the absorption box.

[0015] As a preferred embodiment of the present invention, the conveying device further includes a plurality of vertical plates, which are arranged at equal intervals along the surface of the conveyor belt. The vertical plates are vertically arranged on the surface of the conveyor belt, and the space between two adjacent vertical plates is a placement space. By controlling the conveying speed of the conveyor belt and the speed at which the ore falls from the reducing container onto the conveyor belt, equally divided ore samples are placed in the corresponding placement spaces.

[0016] As a preferred embodiment of the present invention, it further includes a plurality of stationary units, which are equally spaced along the ore conveying direction at one end of the conveying container near the testing container. The plurality of stationary units correspond to and match a plurality of placement spaces at one end of the testing container, with each stationary unit located in a corresponding placement space. Each stationary unit includes a lifting cylinder and a hollow stationary cover. The lifting cylinder is vertically disposed inside the conveying container, and the stationary cover is connected to the output end of the lifting cylinder. The stationary cover is used to fasten the ore sample in the corresponding stationary space.

[0017] As a preferred embodiment of the present invention, the settling unit further includes a settling box, a settling pump, and a settling pipe. The settling box is disposed outside the conveying container, and the two ends of the settling pipe are respectively connected to the settling box and the settling cover. The settling pump is disposed on the settling box.

[0018] The beneficial effects of this invention are as follows: This solution utilizes a sealed connection between the crushing assembly and the crushing container. During the crushing process, the ore emits a large amount of dust, which is confined to the crushing container and cannot escape. This ensures that the detection device near the crushing unit is not affected by the dust, guaranteeing its accuracy. It also solves the problem that when the distance between the crushing unit and the detection device is reduced, the large amount of dust emitted during crushing can easily accumulate at the detection device, reducing its accuracy.

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0022] Please see Figures 1-8 This embodiment provides a containerized automatic sampling system. Along the ore conveying direction, it sequentially includes a crushing assembly 1, a reducing assembly 2, and a detection assembly 3 connected to each other. It also includes interconnected and hollow crushing containers 4, reducing containers 5, and a detection container 6. The crushing containers 4, reducing containers 5, and detection containers 6 correspond to and match the crushing assembly 1, reducing assembly 2, and detection assembly 3, respectively. Each assembly is housed within its corresponding container. Taking the relationship between the crushing assembly 1 and the crushing container 4 as an example, the crushing container 4 is provided with a crushing output port 401 and a crushing input port 402. The crushing assembly 1 includes a crushing input end 101, a crushing device 102, and a crushing output end 103 connected in sequence. The crushing device 102 is housed within the crushing container 4. The cross-sectional shape of the crushing input end 101 corresponds to the crushing output end 403. The cross-sectional shape of the inlet 402 is matched, and the connection between the two is sealed. The cross-sectional shape of the crushing output end 103 is matched with the cross-sectional shape of the crushing output port 401, and the connection between the two is sealed. Through the sealed connection between the crushing assembly 1 and the crushing container 4, during the crushing process of the crushing device 102, the ore emits a large amount of dust due to the crushing effect. This dust can only drift inside the crushing container 4 and cannot overflow outside the crushing container 4. This ensures that the detection device located near the crushing device 102 will not be interfered with by the dust, ensuring the detection accuracy of the detection device. This solves the problem that when the distance between the crushing device 102 and the detection device becomes closer, the large amount of dust emitted by the crushing device 102 during the crushing process of the ore makes it easy for the emitted dust to accumulate at the detection device, reducing the detection accuracy of the detection device.

[0023] It should be noted that, in order to reduce the dust concentration inside the crushing container 4, this solution also includes a dust collection device 7. The dust collection device 7 includes a dust pump 701, a dust suction pipe 702, and a dust collection box 703. The dust collection box 703 is located outside the crushing container 4. Both ends of the dust suction pipe 702 are connected to the crushing container 4 and the dust collection box 703, respectively. The dust pump 701 is mounted on the dust collection box 703. With the dust collection device 7, when the dust pump 701 starts working, the dust inside the crushing container 4 will be absorbed into the dust collection box 703 by the dust suction pipe 702 due to air pressure, thus reducing the dust concentration inside the crushing container 4.

[0024] It is worth noting that this solution is a device for partial sampling and testing of ore. Since the ore sent to the crushing assembly 1 for crushing is transported from the quarry, it is typically large in volume, while the ore sample required for testing does not need to be that large. Therefore, crushing is often necessary. Furthermore, since the volume and quantity of the ore required for testing are small, it is not necessary to send all the crushed ore to the testing assembly 3 for testing. Therefore, in this solution, the crushing output end 103 only sends the ore required for testing to the reducing assembly 2, while the remaining crushed ore will be transported through the other output ends of the crushing assembly 1, which will not be elaborated here.

[0025] Furthermore, the sizing assembly 2 includes a sizing input end 201, a sizing device 202, and a sizing output end 203 connected in sequence. The sizing device 202 is located inside the sizing container 5. The sizing input end 201 is interconnected with the crushing output end 103, and the sizing output end 203 is interconnected with the detection assembly 3. The sizing container 5 is provided with a sizing input port 501 and a sizing output port 502. The cross-sectional shape of the sizing input end 201 matches the cross-sectional shape of the sizing input port 501, and the connection between the two is sealed. The cross-sectional shape of the sizing output end 203 matches the cross-sectional shape of the sizing output port 502, and the connection between the two is sealed. Here, it should be noted that the function of the sizing device 202 in this scheme is to perform equal-volume sizing of the ore sent to the sizing device 202 after crushing, so that the crushed ore can be sent to the detection device for detection in an equal-volume form. Because the sizing device 202 also causes dust to splash during the ore equalization process, the dust concentration inside the sizing container 5 increases. Therefore, in order to prevent the dust inside the sizing container 5 from accumulating at the detection device, the cross-sectional shape of the sizing input end 201 matches the cross-sectional shape of the sizing input port 501, and the connection between the two is sealed. Similarly, the cross-sectional shape of the sizing output end 203 matches the cross-sectional shape of the sizing output port 502, and the connection between the two is sealed. Through the sealed connection between the sizing assembly 2 and the sizing container 5, the ore emits a large amount of dust during the sizing device 202's equalization process. This dust can only drift inside the sizing container 5 and cannot overflow outside, thus ensuring that the detection device located near the sizing device 202 is not interfered with by the dust.

[0026] Furthermore, to facilitate the transportation of ore from the shrink-fit container 5 to the inspection container 6, this solution also includes a conveying device 8. The conveying device 8 includes a conveyor belt 801, which is positioned between the shrink-fit container 5 and the inspection container 6. The inspection container 6 has an inspection input port 601. The end of the conveyor belt 801 is connected to the inspection input port 601, and the front end of the conveyor belt 801 is lower than the height of the shrink-fit output port 502. Through the conveyor belt 801, the ore in the shrink-fit container 5 first moves to the front end of the conveyor belt 801. Then, due to the conveying effect of the conveyor belt 801, the ore on the conveyor belt 801 moves to the end of the conveyor belt 801, ultimately moving the ore into the inspection container 6, thus realizing the transfer of sampled ore from the shrink-fit container 5 to the inspection container 6. It should be noted that, in order to ensure that the ore inside the shrinking container 5 falls onto the conveyor belt 801, the front end of the conveyor belt 801 is lower than the height of the shrinking output port 502, and the distance between the conveyor belt 801 and the shrinking output port 502 is less than 1 cm. With this setting, when the equally divided ore inside the shrinking container 5 moves out of the shrinking container 5, it can all fall onto the conveyor belt 801.

[0027] As described in the above embodiments, due to the height difference between the conveyor belt 801 and the shrinkage output port 502 of the shrinkage container 5, dust will be generated when the ore inside the shrinkage container 5 falls onto the conveyor belt 801. Therefore, in order to prevent this dust from accumulating on the detection device, this solution also includes a hollow conveyor container 9. The two ends of the conveyor container 9 are respectively attached to the shrinkage container 5 and the detection container 6. The conveyor belt 801 is set inside the conveyor container 9. By setting the conveyor container 9, this dust can only accumulate inside the conveyor container 9 and cannot accumulate on the detection device.

[0028] Furthermore, in order to eliminate the dust located inside the conveying container 9, this solution also includes an absorption device 10. The absorption device 10 includes an absorption pump 1001, an absorption pipe 1002, and an absorption box 1003. The absorption box 1003 is located outside the conveying container 9. The two ends of the absorption pipe 1002 are connected to the conveying container 9 and the absorption box 1003, respectively. The absorption pump 1001 is located on the absorption box 1003. With the absorption device 10 installed, when the absorption pump 1001 starts working, the dust located inside the conveying container 9 will be absorbed into the absorption box 1003 by the absorption pipe 1002 due to the air pressure, thereby reducing the dust concentration inside the conveying container 9.

[0029] Furthermore, as described in the above embodiments, the function of the sizing device 202 is to divide the crushed ore into equal portions, and the ore after equal division will be transported from the sizing container 5 to the conveyor belt 801 under the action of the sizing device 202. Based on this, in order to realize that the ore located on the conveyor belt 801 can also be transported to the testing container 6 in an equal-divided form, the conveying device 8 of this solution also includes several vertical plates 802. The several vertical plates 802 are arranged at equal intervals along the surface of the conveyor belt 801. The vertical plates 802 are vertically arranged on the surface of the conveyor belt 801, and the space between two adjacent vertical plates 802 is the placement space. By controlling the conveying speed of the conveyor belt 801 and the speed at which the ore falls from the sizing container 5 onto the conveyor belt 801, the ore samples with equal division can be placed in the corresponding placement space.

[0030] Furthermore, it should be noted that since this solution connects the crushing assembly 1, the reducing assembly 2, and the detection assembly 3 through a compact structure, in actual practice, when equally divided ore is conveyed to the conveyor belt 801, the ore's temperature has not yet dropped, causing dust originally attached to the ore surface to float on the conveyor belt 801. When the ore on the conveyor belt 801 is conveyed into the detection container 6, dust will float inside the detection container 6, potentially accumulating in the detection assembly 3. Therefore, to address these issues, this solution also includes several stationary units 11. These stationary units 11 are evenly spaced along the ore conveying direction within the conveying container 9 near the detection container 6. Each stationary unit 11 corresponds to a placement space near the detection container 6, with each stationary unit 11 located in its corresponding placement space. Each stationary unit 11 includes a lifting cylinder 1101 and an internal... An empty settling cover 1102 and a lifting cylinder 1101 are vertically installed inside the conveyor container 9. The settling cover 1102 is connected to the output end of the lifting cylinder 1101 and is used to lock the ore sample in the corresponding settling space. With this setup, when the conveyor belt 801 transports the equally distributed ore sample to one end near the testing container 6, the conveyor belt 801 will stop moving. At this time, the settling unit 11 starts working, controlling the settling cover 1102 to descend through the lifting cylinder 1101, so that the settling cover 1102 locks the ore sample in the corresponding settling space. At this time, the surface of the settling cover 1102 and the conveyor belt 801 together form a sealed space, preventing the ore sample in the sealed space from dispersing dust into the conveyor container 9. At the same time, after a period of settling, once the temperature of the ore sample has cooled down, the dust will no longer disperse from the ore surface. Then, the settling unit 11 is reset, and the conveyor belt 801 is restarted to transport the ore into the testing container 6.

[0031] Furthermore, it should be noted that during the period when the settling cover 1102 is fastened in the corresponding settling space, the ore will continuously release dust. Before the settling unit 11 is reset, it is necessary to eliminate the dust that has been released in the sealed space. Based on this, the settling unit 11 of this solution also includes a settling box 1103, a settling pump 1104, and a settling pipe 1105. The settling box 1103 is set outside the conveying container 9. The two ends of the settling pipe 1105 are respectively connected to the settling box 1103 and the settling cover 1102. The settling pump 1104 is set on the settling box 1103. With the settling pump 1104, when the settling pump 1104 starts to work, the dust in the sealed space will be absorbed into the settling box 1103 by the settling pipe 1105 due to the air pressure, thus eliminating the dust that has been released in the sealed space.

[0032] Furthermore, it should be noted that, as mentioned in the above embodiments, there is floating dust inside the conveying container 9, and the conveying container 9 and the inspection container 6 are interconnected. Therefore, there is a possibility that the floating dust inside the conveying container 9 may accumulate inside the inspection container 6. To address this issue, the conveying device 8 of this solution further includes several dustproof adhesive layers 803, which correspond to and match several vertical plates 802. Each dustproof adhesive layer 803 is disposed on the four end faces of the corresponding vertical plate 802. The dustproof adhesive layer 803 can deform to achieve its contact with... The end faces of the detection input port 601 are in contact with each other. Furthermore, in this design, the conveyor belt 801 is centrally located within the detection input port 601; that is, the projection of the conveyor belt 801 onto the end face of the detection input port 601 is centered on the end face of the detection input port 601. Additionally, in this design, the conveyor belt 801, the vertical plates 802 located at both ends of the conveyor belt 801, and the corresponding dustproof adhesive layers 803 together seal the detection input port 601. This arrangement prevents dust floating inside the conveyor container 9 from accumulating inside the detection container 6. It should be noted that in this design, the depth of the detection input port 601 is greater than the distance between two adjacent vertical plates 802. This arrangement ensures that two dustproof adhesive layers 803 are always in contact with the end faces of the detection input port 601.

[0033] Furthermore, in this solution, there is another issue: within several placement spaces of the conveyor belt 801, there are placement spaces undergoing static processing and placement spaces awaiting static processing. When the placement space located near the testing container 6 within the conveyor belt 801 completes static processing, the conveyor belt 801 restarts, transporting the ore samples that have completed static processing to the testing container 6. This continues until the ore samples awaiting static processing move to the static unit 11, at which point the conveyor belt 801 stops, and static processing is performed on the ore samples that have not yet undergone static processing. During this process, there is a special node vertical plate 802, where one end of this special node vertical plate 802 contains the ore samples that have completed static processing, while the other end contains the ore samples that have not yet completed static processing. In this solution, this special node vertical plate 802 is defined as node plate 12.

[0034] Due to the location of this node plate 12, and the fact that the ore samples that have not undergone settling treatment are prone to emitting dust, dust emitted by the unset ore samples may float into the settling ore samples. However, it is important to emphasize that during the operation of the conveyor belt 801, the airflow caused by the transport direction of the conveyor belt 801 is directed towards the unset ore samples. Therefore, during the operation of the conveyor belt 801, the dust emitted by the unset ore samples cannot float into the placement space of the settling ore samples. Only when the conveyor belt 801 stops moving or decelerates when it is about to stop, is it possible for dust emitted by the unset ore samples to float into the placement space of the settling ore samples.

[0035] Furthermore, in this solution, due to the characteristics of the node plate 12, it is located outside the detection input port 601 during the period when the control conveyor belt 801 is stopped. Therefore, to address the issue that dust emitted from ore samples that have not undergone settling treatment may drift into the placement space of ore samples that have undergone settling treatment after the conveyor belt 801 stops working, this solution also includes several positioning sensors. These positioning sensors are matched with several vertical plates 802, and each positioning sensor is set on the corresponding vertical plate 802 to determine the position of each vertical plate 802. With this setup, the control program can control the node plate 12 to be positioned below the stationary unit 11 closest to the end of the inspection container 6 after the conveyor belt 801 stops working. Specifically, for ease of description, this solution defines the stationary cover 1102 of the stationary unit 11 closest to the end of the inspection container 6 as the node cover 13. The minimum setting height of the node cover 13 after resetting is 2mm-4mm higher than the top surface of the node plate 12, and the outer end face of the node cover 13 is in contact with the inner end face of the node plate 12. In addition, the bottom end face of the node cover 13 is provided with adsorption slots, which are used to adsorb dust emitted by the ore sample that has not completed the stationary treatment at one end of the node plate 12.

[0036] As mentioned in the above embodiments, the position where the settling cover 1102 connects to the settling tube 1105 also serves to adsorb dust from the ore sample located in the settling space. It should be emphasized that, in order to ensure the effectiveness of the settling cover 1102 in adsorbing dust from the ore sample in the settling space, the position where the settling cover 1102 connects to the settling tube 1105 is located on the inner end face of the settling cover 1102. Specifically, the settling cover 1102 has a horizontal slot 1301 and a vertical slot 1302. The vertical slot 1302 is vertically disposed at the top inside the settling cover 1102. The two ends of the vertical slot 1302 are connected to the settling tube 1105 and one end of the horizontal slot 1301, respectively. The other end of the horizontal slot 1301 is connected to the interior of the settling cover 1102. The position where the horizontal slot 1301 connects to the settling cover 1102 is located at the top inside the settling cover 1102.

[0037] The structure of the node cover 13 is the same as that of the static cover 1102. It also has the effect of adsorbing the dust of the ore sample in the static space after being fastened into the corresponding static space. At the same time, the bottom end face of the node cover 13 is also provided with adsorption slots for adsorbing the dust emitted by the ore sample that has not been statically treated at one end of the node plate 12.

[0038] In addition, it should be noted that in this solution, in order to optimize the number of air pipes set in the node cover 13, the horizontal slot 1301 and the adsorption slot share the same stationary pump 1104 to achieve the effect of adsorbing dust in different directions.

[0039] Specifically, the node cover 13 of this solution also includes a sliding slot 1303, a sliding plate 1304, and a sliding spring 1305. The sliding slot 1303 is vertically disposed within the node cover 13, and its axial direction is perpendicular to the axial direction of the horizontal slot 1301. The two ends of the sliding slot 1303 are respectively connected to the adsorption slot and the vertical slot 1302. The sliding plate 1304 is slidably disposed within the sliding slot 1303. Under normal conditions, the sliding plate 1304 prevents the horizontal slot 1301 and the vertical slot 1302 from communicating with each other. The sliding spring 1305 is disposed within the sliding slot 1303, and its two ends are respectively connected to the sliding plate 1304. 304 is connected to node cover 13; the sliding plate 1304 has a through slot 1306, the axis of the through slot 1306 is parallel to the axis of the horizontal slot 1301, and the sliding plate 1304 can lock or unlock the state in which the through slot 1306 and the horizontal slot 1301 are connected by sliding; the sliding plate 1304 also has a number of connecting slots 1307, the number of connecting slots 1307 are equally spaced along the length of the sliding plate 1304, the axis of the connecting slots 1307 is parallel to the axis of the sliding plate 1304, the two ends of the connecting slots 1307 are connected to the adsorption slot and the vertical slot 1302 respectively, and the connecting slots 1307 and the through slot 1306 are not connected to each other. With this setup, under normal conditions, the bottom of the sliding plate 1304 extends to the bottom surface of the node cover 13 due to the force of the sliding spring 1305. At this time, the bottom surface of the sliding plate 1304 is 2mm-4mm higher than the top surface of the node plate 12, and the through slot 1306 is in a cooperative relationship with the horizontal slot 1301, which is disconnected from each other. At this time, the stationary pipe 1105 is connected to the connecting slot 1307. When the stationary pump 1104 starts to work, the connecting slot 1307 will generate a negative pressure effect, adsorbing the dust emitted by the ore sample that has not completed the stationary treatment to the node plate 12. When the node cover 13 is fastened into the stationary space, the sliding plate 1304 will retract into the sliding slot 1303, and the through slot 1306 will lock its connection with the horizontal slot 1301. The connecting slot 1307 will be in a sealed fit with the bottom surface of the stationary space. When the stationary pump 1104 starts to work, the horizontal slot 1301 will generate a negative pressure effect, adsorbing the dust of the ore sample fastened inside the node cover 13.

[0040] It is important to note here that in this scheme, during the operation of the settling unit 11, the node plate 12 is not in a sealed fit with the detection input port 601. This is because, as mentioned above, dust emitted from ore samples that have not undergone settling treatment may drift into the storage space of ore samples that have undergone settling treatment only when the conveyor belt 801 stops moving or is about to stop and decelerates. If the node plate 12 is in a sealed fit with the detection input port 601 during the operation of the settling unit 11, dust emitted from ore samples that have not undergone settling treatment may drift towards the inner wall of the detection input port 601. When the conveyor belt 801 operates subsequently, the movement of the vertical plate 802 will scrape the dust adhering to the inner wall of the detection input port 601 into the interior of the detection container 6.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
