Description

Technical Field

[0001] This invention belongs to the technical field of ore sampling equipment, specifically relating to an online real-time analysis system for automatic ore sampling. Background Technology

[0002] In exploration or mineral resource development, drilling tools are driven underground. Usually, drilling rigs are used to drive the drilling tools to break the rock at the bottom of the hole, and to lower or pull them into the hole to obtain physical geological data in order to explore the underground geology and mineral resources. Traditional drilling rigs include sampling, operation and analysis functions in the drilling process.

[0003] However, in the existing automatic sampling process of drilling rigs, the vacuum pump first operates, and the vacuum draws drilling particles from the dust cover of the drilling rig into the pipe and into the collection device. After the collection is completed, the vacuum pump stops working, the valve opens, and the collected sample flows into the test container. After the sampling is completed, the dust removal process is carried out. The three-way valve opens the air compressor branch and closes the vacuum pump pipe. The high-pressure air from the air compressor passes through the valve to discharge the residual particles in the collection device. That is, the sampling process needs to be interrupted every time the dust removal process is carried out, and the air compressor and vacuum pump need to be repeatedly turned on and off, which increases the operating burden of the air compressor and vacuum pump.

[0004] Further improvements are needed to address the shortcomings of existing technologies. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an online real-time analysis system for automatic ore sampling to solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an online real-time analysis system for automatic ore sampling, comprising a collection device, a vacuum pump, an air compressor, and a dust cover. A side passage pipe is connected to the side wall of the dust cover. The collection device includes a base, an airflow cylinder, three collection cylinders, and a sealing plate. The airflow cylinder is located in the middle of the upper side of the base. The three collection cylinders are evenly distributed in a ring on the side of the airflow cylinder. Both the airflow cylinder and the collection cylinders are open at their upper and lower ends. A side passage is provided on the arc-shaped side of the collection cylinder near its upper end. The lower end opening of the collection cylinder is a contracting opening. The airflow cylinder has a narrow throat structure with its inner diameter decreasing and then increasing near its lower end. A recovery box is located below the lower end of the airflow cylinder, and three horizontal pipes are connected to the narrow throat. The ends of the three horizontal pipes point towards the lower end of the collection cylinder. A turbine fan is installed inside the airflow cylinder. A first gear is fixedly connected to the shaft of the turbine fan. The lower side of the first gear is circular. The system features an annular protrusion structure. The lower annular protrusion of the first gear is rotatably sleeved on the upper end of the airflow tube. The first gear meshes with three second gears, each corresponding to a collection tube. The lower side of each second gear has an annular protrusion structure, which is rotatably sleeved on the upper end of the collection tube. Sealing plates are provided on the upper sides of the first and second gears. The middle part of the sealing plate is rotatably connected to the middle shaft of the first gear via a rolling bearing, and the middle shaft of the second gear is rotatably connected to the corresponding part of the sealing plate via a rolling bearing. The sealing plate has three first through holes, three second through holes, and one third through hole. Each collection tube communicates with one of the corresponding first and second through holes, and the airflow tube communicates with the third through hole. Three support plates are fixed on the base, each corresponding to a collection tube. Each support plate is positioned below its corresponding collection tube, and a test container is placed on the support plate.

[0007] The second gear has a 2 / 3 π arc fan-shaped hole. A trigger switch is installed on the central shaft of the second gear. The three trigger switches form a control assembly. The trigger switch consists of an adjustment plate, a trigger ring, and an internal circuit. The adjustment plate is fixed on the central shaft of the second gear, and the arc of the adjustment plate corresponds to the arc of the fan-shaped hole. The trigger ring is fixedly connected to the sealing plate. The trigger ring has two guide plates, which are located on the side near the first through hole. The three sets of adjustment plates and guide plates serve as control switches for three independent circuits inside the control assembly.

[0008] The side opening of the collecting cylinder is connected through a ring pipe, which is connected to the side opening through a PVC steel wire pipe. The first and third through holes are connected to the air compressor through a PVC steel wire pipe, and the second through hole is connected to the vacuum pump through a PVC steel wire pipe.

[0009] A first valve is provided at the lower opening of the collection cylinder, and a second valve is provided at the side opening of the collection cylinder. Both the first valve and the second valve are connected to the control component via signal lines.

[0010] Preferably, a first filter screen is provided at the upper port of the collection cylinder, and a second filter screen is provided at the connection between the dust cover and the side passage pipe, wherein the pore size of the first filter screen is smaller than that of the second filter screen.

[0011] Preferably, the first gear includes an inner ring and an outer ring arranged concentrically, wherein the inner ring and the outer ring are fixedly connected by a support rod.

[0012] Preferably, the horizontal tube port is an enlarged diffuser-shaped port, and a third valve is provided at the horizontal tube port. The third valve is connected to the control component via a signal line.

[0013] The beneficial effects of this invention are as follows: During the drilling process of the drilling rig of this invention, during the automatic sampling process, high-pressure air generated by the air compressor enters the airflow cylinder through the third through hole, blowing the turbine fan and driving the first gear to rotate. The first gear drives the second gear to rotate. The opening and closing of the control component circuit is controlled by the adjusting plate and guide plate, so that the collection cylinder can sequentially achieve the cleaning, sampling, and data analysis process. At the same time, the three collection cylinders are in different states, realizing continuous and uninterrupted automatic sampling and real-time analysis, improving the efficiency of automatic sampling and real-time analysis. The cleaning step after each sampling ensures the cleanliness of the collection cylinder. Moreover, the whole process does not require repeated opening and closing of the air compressor and vacuum pump, avoiding repeated opening and closing of the air compressor and vacuum pump, and reducing the workload of the air compressor and vacuum pump.

[0026] In this embodiment, a first valve 701 is provided at the lower opening of the collection cylinder 7, and a second valve 702 is provided on the side opening of the collection cylinder 7. Both the first valve 701 and the second valve 702 are connected to the control component through signal lines, and the first valve 701 and the second valve 702 correspond to the numbers of the collection cylinder 7, that is, ① the first valve 701 and the second valve 702 on the collection cylinder 7, ② the first valve 701 and the second valve 702 on the collection cylinder 7, and ③ the first valve 701 and the second valve 702 on the collection cylinder 7.

[0027] In this embodiment, a first filter screen 16 is provided at the upper port of the collection cylinder 7, and a second filter screen 18 is provided at the connection between the dust cover 4 and the side pipe 17.

[0028] In this embodiment, the first gear 10 includes an inner ring 1001 and an outer ring 1002 arranged concentrically, wherein the inner ring 1001 and the outer ring 1002 are fixedly connected by a support rod 1003, so that the gas in the third through hole 1203 can enter the airflow cylinder 6.

[0029] In this embodiment, the port of the horizontal tube 9 is an enlarged diffuser port to facilitate gas collection. A third valve 901 is provided at the port of the horizontal tube 9, and the third valve 901 is connected to the control component via a signal line.

[0030] Working principle of the invention: During the drilling process of the drilling rig of the present invention, during the automatic sampling process, the vacuum pump 2 and the air compressor 3 are turned on. The high-pressure air generated by the air compressor 3 enters the airflow cylinder 6 through the third through hole 1203, blowing the turbine fan 8 and driving the first gear 10 to rotate. The first gear 10 drives the second gear 11 to rotate. When ① the first through hole 1201 is connected to ① the sector hole 1101, ② the second through hole 1202 is connected to ② the sector hole 1101, and ③ the sector hole 1101 is blocked by the sealing plate 12, at this time ① adjustment When segment 19 contacts guide 2001, and when adjusting segment 19 separates from guide 2001, adjusting segment 3 separates from guide 2001. The circuit connecting adjusting segment 19 and guide 2001 is closed. At this time, the control component controls valve 1 to open, valve 2 to close, and valve 3 to open. High-pressure air generated by air compressor 3 enters collection cylinder 7 through first through hole 1201 and is ejected from first valve 701 to clean collection cylinder 7. As the area contracts, according to Bernoulli's law, the gas flow velocity across section 9 increases, the pressure decreases, and suction is generated. This suction draws the residual sample particles ejected from collection cylinder 7 into the airflow cylinder 6 and then sprays them into the recovery box for collection, reducing the amount of residual sample particles scattered in the air. The control component controls the first valve 701 to close, the second valve 702 to open, and the third valve 901 to close, using collection cylinder 7 for sampling. Vacuum pump 2 passes sequentially through the second through hole 1202, the PVC steel wire tube, and the side pipe 17. Sample particles inside the dust cover 4 are filtered through the second filter 18 and drawn into the collection cylinder 7, preventing large particles from entering the ② collection cylinder 7. Simultaneously, they are filtered through the first filter 16 to prevent particles in the ② collection cylinder 7 from being drawn into the vacuum pump. The control component controls the opening of the ③ first valve 701, the closing of the ③ second valve 702, and the closing of the ③ third valve 901, causing the sample particles in the ③ collection cylinder 7 to flow into the corresponding test container 14 for data analysis. As the first gear 10 drives the second gear 11 to rotate, such as... Figure 5-7 As shown, each collection tube 7 sequentially performs cleaning, sampling, and data analysis steps to achieve continuous and uninterrupted automatic sampling and real-time analysis. The cleaning step after each sampling ensures the cleanliness of the collection tube 7.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
