[0052] Example

[0053] like Figure 1-Figure 4As shown, the multi-product blowing system proposed in the embodiment of the present invention includes: an air storage part 1, an air intake component 2, a solenoid valve 3 and a blowing component 4;

[0054] The interior of the gas storage part 1 is divided into a first cavity 13 and a second cavity 14. The gas storage part 1 is connected to the gas intake component 2, which is used to supply the required gas in the first cavity 13 and the second cavity 14;

[0055] The solenoid valve 3 is provided on the side wall of the gas storage part 1, and the solenoid valve 3 is connected and communicated with the first cavity 13 and the second cavity 14 respectively through the side wall of the gas storage part 1;

[0056] The blowing assembly 4 is arranged on the side wall of the gas storage part 1 and is connected to the solenoid valve 3;

[0057] The first cavity 13 is used to store gas required by the spray assembly 4 , and the second cavity 14 is used to store gas required to drive the solenoid valve 3 so that the solenoid valve 3 controls the on-off between the first cavity 13 and the spray assembly 4 .

[0058] Specifically, the gas storage unit 1 is a container for storing gas. The interior of the gas storage unit 1 is divided into a first cavity 13 and a second cavity 14. The first cavity 13 is used to store the gas required by the blowing assembly 4, and the second cavity 14 is used to store the gas required to drive the solenoid valve 3. The gas required by the blowing assembly 4 is compressed air, and the gas required to drive the solenoid valve 3 is pilot air.

[0059] The air intake assembly 2 is connected to the air storage part 1. The air intake assembly 2 can provide the compressed air supply required by the spray assembly 4 in the first cavity 13. The air intake assembly 2 can also provide the pilot air required to drive the solenoid valve 3 in the second cavity 14.

[0060] The solenoid valve 3 is a control element. By controlling the solenoid valve 3, the on / off between the first cavity 13 and the spray assembly 4 can be controlled, thereby controlling whether the spray assembly 4 is working. The solenoid valve 3 is electrically connected to the control center, which is a computer. The solenoid valve 3 can start or stop according to the instructions given by the control center. The solenoid valve 3 is directly connected to the first cavity 13 and the second cavity 14 through the air storage part 1, which saves the connecting pipes between the solenoid valve 3 and the first cavity 13 and between the solenoid valve 3 and the second cavity 14, reduces the assembly difficulty for technicians, and improves the assembly speed of the equipment by technicians. The solenoid valve 3 is an existing technology and can be obtained through procurement.

[0061] The injection assembly 4 is used to sort materials. It works in conjunction with the optoelectronic intelligent recognition system on the dry sorter. Using a multi-spectral imaging system combining broadband X-rays with visible light, the assembly intelligently analyzes and identifies coal and gangue. The assembly then controls high-pressure air flow to target the materials, achieving fully automated raw coal sorting. Optoelectronic intelligent recognition is an existing technology. It uses a dual-energy X-ray detector to collect molecular component signals; a visible light array sensor to collect surface texture information and reflectivity anisotropy. Information fusion training employs a deep learning algorithm to identify coal and gangue impurities, and the identification results are output to the actuator.

[0062] The multi-product blowing system provided by the embodiment of the present invention integrates the first cavity 13 and the second cavity 14 into an air storage part 1, so that the first cavity 13 is directly connected to the solenoid valve 3 through the side wall of the air storage part 1, and the second cavity 14 is directly connected to the solenoid valve 3 through the side wall of the air storage part 1. Compared with the existing technology, it not only saves the objects for storing gas, that is, one air storage part 1 can store both pilot gas and compressed air, but also saves the connecting pipes between the solenoid valve 3 and the first cavity 13 and between the solenoid valve 3 and the second cavity 14, avoids the problem of complicated connecting pipes when connecting the control valve and the air storage chamber and the structure for storing pilot gas, reduces the assembly difficulty of technicians, and improves the assembly speed of technicians on the equipment, thereby effectively solving the technical problems existing in the existing technology.

[0063] like Figure 1-Figure 2 as well as Figure 4 As shown, in a specific implementation, the air storage part 1 has a first opening and a second opening at two opposite ends thereof, the cross-section of the air storage part 1 along the vertical direction is an isosceles trapezoid, the interior of the air storage part 1 is provided with a partition plate 12, the partition plate 12 divides the inner cavity of the air storage part 1 into a first cavity 13 and at least one second cavity 14, a first connecting port 15 and a second connecting port 16 are provided on the inclined surface of the air storage part 1, the first connecting port 15 is connected to the first cavity 13, and the second connecting port 16 is connected to the second cavity 14; wherein, the first opening is sealed, and the second opening is connected to the air intake component 2 so that the air intake component 2 supplies the required gas in the first cavity 13 and the second cavity 14, the solenoid valve 3 supplies the gas required by the blowing component 4 to the first cavity 13 through the first connecting port 15, and the second connecting port 16 is used to supply the gas required to drive the solenoid valve 3 to operate through the second cavity 14, the solenoid valve 3 is distributed on the inclined surface of the air storage part 1, and the blowing component 4 is provided on the top surface of the air storage part 1.

[0064] Specifically, the gas reservoir 1 has a first opening and a second opening at opposite ends. This structural design facilitates the supply of required gas from the air intake assembly 2 to the first cavity 13 and the second cavity 14 within the gas reservoir 1. The gas reservoir 1 has an isosceles trapezoidal cross-section along the vertical direction. This structural design facilitates the installation of the solenoid valve 3 through the inclined surface of the gas reservoir 1 and the installation of the blowing assembly 4 through the top of the gas reservoir 1, effectively reducing the difficulty of device assembly and improving the stability of the connection structure between the device and the gas reservoir 1.

[0065] The number of partition plates 12 can be determined according to the number of solenoid valves. Technicians can set up multiple partition plates 12 to divide the gas storage part 1 into a first cavity 13 and at least one second cavity 14, so that the first cavity 13 is used to store the gas required for the blowing assembly 4, and the second cavity 14 is used to store the gas required to drive the solenoid valve 3. The partition plates 12 and the gas storage part 1 can be connected in a fixed manner or in a detachable manner, such as welding, an integrated structure or a bolt connection. In this application, in order to improve the effect of the partition plates 12 in separating the inner cavity of the gas storage part 1 and to ensure the airtightness of the cavity for storing gas after separation, the partition plates 12 and the gas storage part 1 are processed into an integrated structure using an integrated casting process.

[0066] The present application provides a first communication port 15 and a second communication port 16 on the inclined surface of the gas storage portion 1. The number of the first communication port 15 and the second communication port 16 is at least one. The solenoid valve can be directly connected to the first cavity 13 and the second cavity 14 through the first communication port 15 and the second communication port 16. Each solenoid valve corresponds to a first communication port 15 and a second communication port 16. The number of the first vent and the second vent is adapted to the number of the solenoid valves. The technicians can configure the number of the first vent and the second vent according to the number of the solenoid valves. This structural design shortens the distance between the solenoid valve and the first cavity 13, and the lifting device is used for spraying. The first cavity 13 and the second cavity 14 are combined into a whole, that is, the inner cavity of the gas storage part 1 is divided into a first cavity 13 for storing the gas required for the blowing component and a second cavity 14 for storing the gas required for driving the solenoid valve through the partition plate 12, which saves the pipeline required to connect the solenoid valve and the structure for storing the gas required to drive the solenoid valve, and effectively solves the problems of complex connecting pipelines and large construction workload.

[0067] The first opening is sealed, and this structural design can be used to ensure the airtightness in the first cavity 13 and the second cavity 14. The second opening is connected to the air intake component 2 so that the air intake component 2 supplies the required gas in the first cavity 13 and the second cavity 14.

[0068] like Figure 1 As shown, in a specific implementation, the air intake assembly 2 includes:

[0069] A first sealing plate 21, a first pipeline 22, a second pipeline 23, a third pipeline 24, an electrically controlled butterfly valve 25, a plurality of air inlets 26 and an air inlet pipe 27;

[0070] The first sealing plate 21 covers the second opening, and the first end of the first pipeline 22 is connected to the first cavity 13 through the first sealing plate 21, and the first end of the second pipeline 23 is connected to the second end of the first pipeline 22. The intersection of the first pipeline 22 and the second pipeline 23 is connected to the electric-controlled butterfly valve 25, and the side of the electric-controlled butterfly valve 25 facing away from the first pipeline 22 and the second pipeline 23 is connected to the third pipeline 24, and the third pipeline 24 is used to connect to the air source; multiple air inlets 26 are provided on the first sealing plate 21, each air inlet 26 is connected to the second cavity 14 through the first sealing plate 21, and the number of the multiple air inlets 26 is the same as the number of the second cavity 14, and corresponds one to one; the air inlet pipe 27 is connected to the second end of the second pipeline 23, and the air inlet pipe 27 has multiple air outlets 28, which are connected to the air inlet 26, and the number of the multiple air outlets 28 is the same as the number of the air inlet 26, and corresponds one to one.

[0071] Specifically, the first sealing plate 21 is used for sealing. The first sealing plate 21 is sealed on the second opening via a flange. The first sealing plate 21 has an opening in the middle. The first end of the first pipeline 22 passes through the middle opening of the first sealing plate 21 and is connected to the first cavity 13. The second end of the first pipeline 22 is connected to the first end of the three-way pipe fitting. The first end of the second pipeline 23 is connected to the second end of the three-way pipe fitting. The third end of the three-way pipe fitting is connected to and communicates with the electric-controlled butterfly valve 25. The side of the electric-controlled butterfly valve 25 facing away from the three-way pipe fitting is connected to the third pipeline 24. The third pipeline 24 is connected to the gas source, and the electric-controlled butterfly valve 25 is electrically connected to the control center.

[0072] The first sealing plate 21 also has multiple openings, each opening corresponds to a second cavity 14, each air inlet 26 is connected to the corresponding second cavity 14 through the opening, the air inlet pipe 27 is connected to the second end of the second pipeline 23, and the air inlet pipe 27 has multiple air outlets 28, each air outlet 28 corresponds to an air inlet 26, and each air outlet 28 is connected to the corresponding air inlet 26 through a hose.

[0073] The gas source is used to provide the required gas to the gas storage part 1, and the gas source supplies gas to the first pipeline 22 and the second pipeline 23 through the third pipeline 24. The electromagnetic butterfly valve is used to control the on-off between the third pipeline 24 and the first pipeline 22 and the second pipeline 23. The gas in the first pipeline 22 enters the first cavity 13 for storage through the first sealing plate 21, and the gas in the second pipeline 23 passes through the air inlet pipe 27, the air outlet 28 and the air inlet 26 in turn and enters the corresponding second cavity 14 for storage.

[0074] In a specific implementation, the third pipeline 24 is connected to the gas source through a flexible connecting pipeline.

[0075] Specifically, this structural design can prevent the gas source from being subjected to stress, which would cause damage to the gas source.

[0076] like Figure 1 As shown, in a specific implementation, the air intake assembly 2 further includes: a pressure transmitter 29, an oil mist assembly 210, a filter 211 and a filter screen 212;

[0077] The pressure transmitter 29 is provided on the first pipeline 22 for detecting the pressure value of the conveyed gas; the oil mist assembly 210 and the filter 211 are connected in sequence between the second pipeline 23 and the air inlet pipe 27; the filter screen 212 is provided in the third pipeline 24.

[0078] Specifically, the pressure transmitter 29 is an existing technology that can be obtained through procurement. The pressure transmitter 29 is electrically connected to the control center. The pressure transmitter 29 can observe the pressure of the system in the pipeline in real time. When the pressure is too high, a feedback signal is sent to the control center, and the control center controls the gas source to reduce the pressure to ensure the safety of the device when in use; when the pressure is too low, a feedback signal is sent to the control center, and the control center controls the gas source to increase the pressure to ensure the blowing effect of the blowing component 4.

[0079] Oil mist assembly 210 is currently available and can be purchased. When lubrication is required for the air medium, a lubricator is a component designed to add the required lubricant to the air flow. Filter 211 is used to filter water vapor contained in the gas within second pipeline 23, preventing it from entering solenoid valve 3 and potentially damaging it. Filter 211 is currently available and can be purchased. The connections between filter 211 and intake pipe 27, between filter 211 and oil mist assembly 210, and between oil mist assembly 210 and second pipeline 23 are well known to those skilled in the art and will not be detailed here.

[0080] The filter 212 is used to filter impurities contained in the gas in the third pipeline 24. The filter 212 is an existing technology and can be purchased.

[0081] like Figure 1As shown, in a specific implementation, a bypass inlet 5 is provided at the intersection of the first pipeline 22 and the second pipeline 23 , and a bypass inlet 6 is provided on the third pipeline 24 .

[0082] Specifically, this structural design can ensure that the third pipeline 24 is connected to the first pipeline 22 and the second pipeline 23.

[0083] When a problem occurs with the electrically controlled butterfly valve 25, the third pipeline 24 becomes disconnected from the first pipeline 22 and the second pipeline 23. A technician then connects the bypass inlet 5 and the bypass inlet 6 via a hose, allowing the third pipeline 24 to communicate with the first pipeline 22 and the second pipeline 23. If the problem does not occur with the electrically controlled butterfly valve 25, both the bypass inlet 5 and the bypass inlet 6 are normally closed.

[0084] like Figure 1-Figure 3 As shown, in a specific implementation, the blowing assembly 4 includes:

[0085] The transition valve plate seat 41, the transition pipeline 42 and the transition valve plate upper plate 43 are connected in sequence, the transition valve plate seat 41 is connected to the top surface of the air storage part 1, and at least one row of nozzle groups 44 are provided on the side of the transition valve plate upper plate 43 away from the transition pipeline 42, each nozzle group 44 has at least one nozzle, each nozzle is connected to the transition pipeline 42, the transition pipeline 42 is connected to the transition valve plate seat 41, the transition valve plate seat and the transition pipeline 42 are perpendicular to each other, and the transition valve plate upper plate 43 is inclined on the transition pipeline 42; wherein, there are multiple solenoid valves 3, each solenoid valve 3 corresponds to a nozzle, and multiple connecting ports are provided on the transition valve plate seat, each connecting port corresponds to a nozzle, and each solenoid valve 3 is connected to the corresponding nozzle through the corresponding connecting port.

[0086] Specifically, the upper plate 43 of the transition valve plate has at least one row of nozzle groups 44, each nozzle group 44 has at least one nozzle, and each nozzle has an independent air supply channel between the transition pipeline 42 and the transition valve plate seat. Each air supply channel is connected to the corresponding connection port on the transition valve plate seat. Each solenoid valve 3 is connected and connected to the corresponding connection port on the transition valve plate seat, wherein a second cavity 14 can supply air to the corresponding at least one row of nozzle groups 44, or a second cavity 14 can supply air to the corresponding nozzles. The technicians can determine it according to actual needs, and this application does not limit it. The solenoid valve 3 is connected to the corresponding connection port on the transition valve plate seat through a hose. The upper plate 43 of the transition valve plate, the transition pipeline 42 and the transition valve plate seat are processed by welding. The upper plate 43 of the transition valve plate, the transition pipeline 42 and the transition valve plate seat are all made of high-strength aluminum alloy extrusion molding. The specific size can be adjusted arbitrarily according to actual processing and production. The number of nozzle groups 44 on the upper plate 43 of the transition valve plate, the number of nozzles in each nozzle group 44, the number of second cavities 14 and the number of solenoid valves 3 can be determined by technicians according to actual needs and are not limited in this application.

[0087] In a specific implementation, a plurality of valve blocks are provided on the side wall of the gas storage portion 1 , the valve blocks are connected to the solenoid valves 3 , each valve block corresponds to a solenoid valve 3 , and the valve blocks are used to control the start and stop of the corresponding solenoid valve 3 .

[0088] Specifically, the valve block is used to control the start and stop of the corresponding solenoid valve 3 , the valve block is electrically connected to the solenoid valve 3 , and the valve block is electrically connected to the control center.

[0089] like Figure 1 As shown, in a specific implementation, the first opening is provided with a second sealing plate 7, the second sealing plate 7 is used to cover the second opening, a control valve is provided on the side of the second sealing plate 7 away from the gas storage part 1, and a 90° elbow 8 is provided on the side of the control valve away from the second sealing plate 7, and the 90° elbow 8 is connected to the first cavity 13 and the second cavity 14 through the control valve and the second sealing plate 7 in sequence.

[0090] Specifically, this structural design can achieve the effect of removing impurities. After the device has been running for a long time, there will be a certain amount of impurities in the first cavity 13 and the second cavity 14. At this time, the technician operates the control valve to connect the first cavity 13 and the second cavity 14 with the 90° elbow 8. The air intake component 2 supplies air to the first cavity 13 and the second cavity 14. The impurities in the first cavity 13 and the second cavity 14 will enter the 90° elbow 8 from the first opening and will be difficult to return to the air storage part 1, thereby achieving the effect of removing impurities from the first cavity 13 and the second cavity 14.
