Description

Technical Field

[0001] The invention relates to a solid material sorting technology, and in particular to a sorting device and a sorting equipment for solid material sorting. Background Art

[0002] Solid materials are usually sorted by air separation according to the weight difference of different materials. That is, the mixed solid materials are placed on the conveyor and transported to the material separation device. The materials to be sorted are first identified by the material identification mechanism, and then the electronic control center of the sorting equipment dispatches the corresponding material separation device to spray high-pressure gas to hit the materials falling from the conveyor according to the identification situation, so that different materials have different falling trajectories, thereby realizing the sorting and removal of solid materials.

[0003] The air flow of the air nozzle of the material distribution device is essentially controlled by the solenoid valve, and each solenoid valve corresponds to one air nozzle. In the existing material distribution device, a row of solenoid valves are installed on the integrated valve body to control each air nozzle. However, due to the large size of the solenoid valve itself, the arrangement and placement of this solenoid valve will result in a limited number of solenoid valves that can be accommodated within a certain length range, which in turn results in the number of air nozzles set within a certain length being limited, and the center distance of the air nozzle is large, which cannot accurately process materials with smaller particle sizes.

[0004] In the prior art (such as utility model patent CN209334265U), there is a method to increase the number of solenoid valves accommodated within a certain length range by distributing the solenoid valve group on both sides of the integrated valve body. However, in the material sorting process, the solenoid valve of the material sorting device will inevitably be damaged after a long period of use and need to be replaced and repaired; and because in the overall equipment for solid material sorting, the material sorting device is placed in a small space close to the conveyor; therefore, when the solenoid valve of the existing material sorting device with the solenoid valve group arranged on both sides of the integrated valve body is repaired, the entire material sorting device is usually disassembled from the sorting equipment, and then the solenoid valve on the material sorting device is repaired. Such a maintenance operation method is time-consuming and difficult to operate.

[0005] When the distributing device is working, the dust from the solid materials adheres to the distributing device or enters the gas path in the integrated valve body of the distributing device, which is the main reason for the damage of the solenoid valve and the malfunction of the distributing device. Therefore, the timely cleaning of the stains on the distributing device is also an urgent problem to be solved. Summary of the invention

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] 1. Easy maintenance. The present invention divides the material separation solenoid valve group into multiple rows and arranges them on the side of the integrated valve body away from the front station. When the solenoid valve is damaged and needs to be replaced, only the solenoid valve on one side needs to be repaired and replaced on the sorting equipment, and there is no need to disassemble the entire material separation device from the sorting equipment, which facilitates maintenance work.

[0030] 2. More suitable for sorting materials with high specific gravity. The design of multi-row solenoid valve group allows more solenoid valves to control the on and off of the air nozzles, so that the arrangement density of the air nozzles can be increased; the air ejected from the air nozzles has a greater force of removal, which is more suitable for removing materials with high specific gravity.

[0031] 3. Make the air jet nozzle on the integrated valve body closer to the front station, which is more conducive to air jet sorting. Because the sorted materials contain water and other factors, the farther the air jet nozzle is from the discharge port of the front station, the more unstable the trajectory of the material's movement is, and the greater the impact on the sorting effect; therefore, the material separation solenoid valve group should be as close to the discharge end of the front station as possible.

[0032] 4. More suitable for sorting fine-sized ore particles. Through the cross-arrangement design of the solenoid valve group and the adaptability design of the internal air path of the integrated valve body, the air nozzle can adapt to the arrangement of the air nozzle with a 6mm axis spacing, making the material separation device suitable for sorting ore particles with a particle size of 6mm, and also improving the accuracy of the blowing of the material separation device.

[0033] 5. The sorting equipment provided by the present invention provides a practical full-process sorting equipment for the sorting of solid materials. The materials to be sorted can be classified after passing through the sorting equipment. In addition, the sorting equipment adopts a material identification mechanism to meet the needs of multi-angle composite shooting and identification, and can realize accurate sorting control of materials. By setting multiple XYR fine-tuning platforms in different directions on the lifting and adjusting components, the installation and position adjustment of multiple cameras in different directions can be realized.

[0034] 6. The material identification mechanism in the sorting equipment can not only adjust the positions of multiple cameras in a large range in the height direction synchronously, but also fine-tune the installation position of the camera in the horizontal direction. By installing a camera on the XYR fine-tuning platform, the XYR fine-tuning platform is installed on the fixed frame through more than one set of lifting and adjusting components in a way that the height can be adjusted synchronously; the positions of multiple cameras can be adjusted in the height direction synchronously. In addition, due to the structural design of the material identification mechanism, the stable identification of the identification mechanism can be guaranteed even if the vibration frequency of the sorting equipment is large during the mineral processing process.

DETAILED DESCRIPTION

[0047] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and meticulously below in conjunction with the accompanying drawings and preferred embodiments of the present invention, but the protection scope of the present invention is not limited to the following specific embodiments.

[0048] Unless otherwise defined, all professional terms used hereinafter have the same meanings as those generally understood by those skilled in the art. The words "one" or "an" and the like used in the patent application specification and claims of the present invention do not indicate a quantity limitation, but indicate the existence of at least one. Words such as "connected" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0049] This embodiment provides a material separation device for solid material separation, such as Figure 1 and Figure 3 As shown, it includes an integrated valve body 1, in which an air cavity 103 is arranged, one end of the integrated valve body 1 is provided with an air nozzle 101, and the other end is provided with an air inlet 102 communicated with the air cavity 103, and the integrated valve body 1 is also equipped with a material dividing solenoid valve group 2 which is connected with the air nozzle 101 and the air cavity 103 to control the size of the air flow; it is characterized in that: the material dividing solenoid valve group 2 is provided with multiple rows, and they are all arranged on the integrated valve body 1 and face the side of the falling direction of the solid material after being sprayed.

[0050] When the material dividing device is working, external high-pressure gas enters the air cavity 103 of the integrated valve body 1 through the air inlet 102, and then enters the material dividing solenoid valve group 2 connected to the air nozzle 101 and the air cavity 103 at the same time, and finally the high-pressure gas is ejected from the air nozzle 101 to hit the falling materials at the front workstation, changing the running trajectory of the falling materials to achieve the sorting of different materials; the material dividing solenoid valve group 2 can control the size and on-off of the air flow, and by controlling the material dividing solenoid valve group 2, materials of different qualities can be sorted, so that the materials can be sorted into several categories.

[0051] After being used for a long period of time, the solenoid valve group 2 will inevitably be damaged due to various reasons. If the solenoid valve group 2 is damaged during operation, it needs to be repaired and replaced. In the prior art, two rows of solenoid valve groups 2 are placed on both sides of the integrated valve body 1. If the solenoid valve near the front station needs to be replaced and repaired, the entire solenoid device needs to be disassembled from the sorting equipment, and then the solenoid valve on the solenoid device needs to be repaired. Such a maintenance operation method is time-consuming and difficult to operate.

[0052] In this embodiment, the material dividing solenoid valve group 2 is divided into a first material dividing solenoid valve group 201 and a second material dividing solenoid valve group 202, which are arranged up and down on the side of the integrated valve body 1 away from the front-end station. When the material dividing solenoid valve group 2 is damaged and needs to be replaced, it is only necessary to repair and replace the material dividing solenoid valve group 2 concentrated on one side on the sorting equipment, and it is no longer necessary to disassemble the entire material dividing device from the sorting equipment. When the placement area of ​​the material dividing device in the sorting equipment is small, it can also be conveniently repaired and replaced. When working, the air nozzle 101 on the integrated valve body 1 can be closer to the front station, which is more conducive to air jet sorting. Because the sorted material contains water and other factors, the farther the air nozzle 101 is from the discharge port of the front station, the more unstable the trajectory of the material's downstream movement is, and the greater the impact on the sorting effect; therefore, the material dividing solenoid valve group 2 needs to be as close to the discharge end of the front station as possible.

[0053] Because in the sorting process of the same batch of materials, the relative position angle between the jet nozzle 101 of the dividing device and the discharge port of the front station is selected after debugging, so when the dividing solenoid valve group 2 is repaired and replaced, it is necessary to ensure that the selected position does not change. Therefore, this setting method of the dividing solenoid valve group that does not require disassembly and change of position is easier to operate, and the sorting accuracy is not affected after maintenance.

[0054] By arranging multiple rows of material-dividing solenoid valve groups 2 on the integrated valve body 1, the material-dividing solenoid valve groups 2 can control more air nozzles 101, so the arrangement density of the air nozzles 101 on the integrated valve body 1 will also be higher, the center distance between the air nozzles 101 will be smaller, the particle size of the material to be processed will be smaller, the sorting will be more accurate and the application range will be wider. The center distance between the air nozzles 101 is 6mm, which can be applied to the ore particles with a minimum particle size of 6mm, and also improves the accuracy of the air blowing of the air nozzle 101. The rejection force of the gas ejected from the air nozzle 101 is also greater, which is more suitable for rejecting materials with a large specific gravity.

[0055] like Figure 1 As shown, in this embodiment, an air passage connecting the air nozzle 101, the material distribution solenoid valve group 2 and the air cavity 103 is provided in the integrated valve body 1, and the lengths of the air passages are kept consistent.

[0056] The total length of the air inlet and outlet channels of each row of the material-dividing solenoid valve group is ensured to be consistent in order to make the pressure of the air flow consistent when it passes through the air inlet and outlet channels from the air cavity and then exits the nozzle. The air inlet channel 104 and the air outlet channel 105 are connected to the material-dividing solenoid valve group 2 in a straight line or a broken line to minimize the total path, because the shorter the line, the better for the blowing effect and blowing time, as well as the release of residual pressure. By designing the internal air path pipeline of the integrated valve body 1, the gas sprayed by the integrated valve body during operation is more stable and has a higher sorting accuracy.

[0057] like Figure 1 As shown, in this embodiment, the material dividing solenoid valve group 2 is provided with two rows, including a first material dividing solenoid valve group 201 and a second material dividing solenoid valve group 202, and the angle between the mounting base surface where the first material dividing solenoid valve group 201 is located and the mounting base surface where the second material dividing solenoid valve group 202 is located is 124 degrees. In the case of this angle design scheme, the total length of the air inlet channel and the air outlet channel of each row of the material dividing solenoid valve group is consistent, and the total path of the air inlet channel 104 and the air outlet channel 105 is the shortest. At this time, both rows of the material dividing solenoid valve groups are more suitable for maintenance personnel to operate the loosening and tightening screws on the sorting equipment.

[0058] like Figure 1 As shown, in this embodiment, the air channel includes an air inlet channel 104 connecting the dosing solenoid valve group 2 and the air cavity 103, and an air outlet channel 105 connecting the dosing solenoid valve group 2 and the air nozzle 101; the air inlet channel 104 is basically perpendicular to the mounting base surface of the dosing solenoid valve group 2; the air outlet channel 105 includes a connecting air channel 1051 and a vertical air channel 1053, the vertical air channel 1053 is connected to the air nozzle 101 and is located on the central axis surface 1052 of the integrated valve body 1; the connecting air channel 1051 connects the vertical air channel 1053 and the dosing solenoid valve group 2, and the connecting air channel 1051 is basically parallel to the air inlet channel 104.

[0059] This airway structure is an adaptive design for the position change of the material distribution solenoid valve group on the integrated valve body. Through the arrangement of the airway position of this structure, firstly, the airway of the material distribution solenoid valve is more convenient during processing, which can be completed by only straight drilling operation, and the workpiece processing accuracy is easy to control; secondly, the relative position of this airway structure and the material distribution solenoid valve makes the assembly accuracy of the material distribution solenoid valve and the integrated valve body high and the airway sealing between them is good.

[0060] like Figure 1 As shown, in this embodiment, the length of the vertical air channel 1053 corresponding to each material-dividing solenoid valve in the material-dividing solenoid valve group 2 is equal, and the sum of the length of the air inlet channel 104 and the connecting air channel 1051 corresponding to each material-dividing solenoid valve is also substantially equal. The air channel design of this structure is adopted to keep the total length of the air channel passing through each material-dividing solenoid valve equal, so that the pressure control of the gas in the integrated valve body is best under the condition of ensuring that the pressure loss of the gas is equal when it is ejected after passing through the air channel.

[0061] like Figure 1 , 2 As shown in FIG. 3 , in the present embodiment, the integrated valve body 1 is provided with a drainage component 3 connected to the air cavity 103 or the air inlet 102; the drainage component 3 includes a drainage solenoid valve 301 and a drainage hole 302 opened on the side wall of the integrated valve body 1, and the drainage hole 302 is installed with the drainage solenoid valve 301; the aperture of the drainage hole 302 is larger than the aperture of the air inlet channel 104.

[0062] The working principle of the evacuation component 3 is as follows: because the cavity diameter of the air cavity 103 is larger than the aperture of the air inlet channel 104, when the intake air enters the air cavity 103 from the air inlet 102 and then enters the air inlet channel 104 inside the material distribution solenoid valve group 2 from the air cavity 103, if the intake air carries impurities, it is easy to accumulate at the intersection between the air cavity 103 and the air inlet channel 104; when the impurity content is high, the air inlet channel 104 will be blocked. To avoid this situation, the impurities in the air cavity 103 can be removed by timing. The method of removing impurities is to open the evacuation solenoid valve 301 of the evacuation hole 302, and use the air pressure in the air cavity 103 to eject impurities through the evacuation hole 302. Because the aperture of the evacuation hole 302 is larger than the aperture of the air inlet channel 104, when the evacuation solenoid valve 301 is opened, the gas in the air cavity 103 will be discharged from the evacuation hole 302 first and will not enter the air inlet channel 104. Because the gas introduced by the material dispensing device before the jet dispensing operation starts is high-pressure gas, if there are liquid impurities such as water, oil, etc. remaining in the air cavity 103 before, they will be vaporized under the pressure of the high-pressure gas; at this time, the evacuation solenoid valve 301 of the evacuation hole 302 is opened to discharge the gas, which will play the role of discharging the liquid impurities.

[0063] like Figure 1As shown, in this embodiment, the integrated valve body 1 includes a cone 106 at the top and a rectangular body 107 at the bottom, which are connected to each other, and a sealing gasket 4 is arranged around the air outlet channel 105 at the connection between the two. The cone 106 is an integrated structural member and is provided with an air outlet channel 105. The airflow is ejected from the air inlet 102 on the cone 106 through the air outlet channel 105. This design avoids the problem of poor sealing and air leakage during the installation of conventional multi-tube air nozzles, which causes deviations in the direction of the ejected airflow, and also avoids impurities such as dust from entering the air cavity 103 inside the integrated valve body 1 through this part of the structure. The sealing gasket 4 is provided to better ensure the air tightness of the cone 106 and the rectangular body 107.

[0064] like Figure 2 As shown, in this embodiment, a sealing cover body 5 is also included, and the integrated valve body 1 and the material distribution solenoid valve group 2 are fixed in the sealing cover body 5. The sealing cover body 5 is provided with an opening 501 at the position corresponding to the air nozzle 101; the sealing cover body 5 is provided with a guide plate 502 extending out of the air nozzle 101 at the opening 501.

[0065] The sealing cover body can protect the integrated valve body 1 and the material distribution solenoid valve group 2 from being hit by materials and prevent impurities from entering the air cavity 103 inside the integrated valve body 1. The opening 501 is used to allow the gas sprayed from the air nozzle 101 to be sprayed to the outside of the sealing cover body 5. During the material distribution process, heavier solid materials tend to fall first. If the materials that fall first hit the air nozzle 101, the air nozzle 101 will be damaged and impurities will enter the air cavity 103 of the integrated valve body 1; by providing a guide plate 502 extending outside the air nozzle 101 at the opening 501 of the sealing cover body 5, even if the materials that fall too early hit the position of the air nozzle 101, the guide plate 502 can guide the materials away from the upper part of the air nozzle 101; avoiding the materials directly hitting the air nozzle 101 and accumulating at the position of the air nozzle 101. According to the specific conditions of the materials to be sorted, a more appropriate 5 mm guide plate 502 is selected, so that the normal jet sorting of the material sorting device can be satisfied and the materials falling on the upper part of the air nozzle 101 can be guided away to the maximum extent.

[0066] like Figure 5 As shown, in this embodiment, an air intake pipe 6 connected to the air intake port 102 is further included, and a filter assembly 7 is arranged on the air intake pipe 6; the filter assembly 7 is a two-stage filter, wherein the first stage is a dust filter 701 for filtering dust impurities in the air intake, and the other stage is a liquid filter 702 for filtering water and oil components in the air intake. The liquid filter 702 for filtering water and oil components in the air intake is close to the air intake port 102 of the integrated valve body 1.

[0067] By setting the filter assembly 7 on the air intake pipe 6, the gas can be further purified before entering the integrated valve body 1, avoiding damage to the integrated valve body 1 due to impurities in the intake air. By setting two filters for filtering different impurities respectively, different impurities can be filtered more specifically, and the filtering effectiveness is better.

[0068] like Figure 4 As shown, in this embodiment, a frame 8 is also included, and both ends of the integrated valve body 1 are mounted on the frame 8. The frame 8 is also equipped with a water spray device 9 for cleaning the sealing cover 5. The water spray device 9 has two water spray nozzles, which are respectively mounted at both ends of the integrated valve body 1; the water spray nozzles can spray water alternately at regular intervals. By providing a cleaning device, dust adhering to the sealing cover of the material distribution device can be washed away.

[0069] The purpose of setting the water spray device 9 is that after the material separation device has been working for a long time, the outer surface of the sealing cover 5 of the material separation device will inevitably adhere to the dust of the sorting material. If the amount of adhesion is too large, it will affect the normal rotation of the material separation device. The material separation device changes the alignment direction of the nozzle 101 by rotating the position according to the different conditions of the required sorting materials to achieve accurate material separation. Therefore, if the material separation device cannot rotate normally, the parabolic trajectory that should be changed when the ore passes through the material separation device will become abnormal, thereby reducing the sorting effect of the material separation device. The water spray nozzle of the cleaning device 9 sprays water intermittently and staggeredly, and the materials adhered to the sealing cover of the material separation device are washed away in time so that they cannot affect the normal rotation of the material separation device, which can further ensure the working stability of the material separation device.

[0070] like Figure 6 and 7 As shown, the present embodiment also provides a sorting device for sorting solid materials, including the above-mentioned material sorting device; the sorting device also includes a feed chute 10, a conveyor belt mechanism 11, a material identification mechanism 12, a material drop bin assembly 13 and an electric control cabinet 14 for receiving the material to be sorted; the inlet end of the conveyor belt mechanism 11 is arranged adjacent to the outlet end of the feed chute 10; the material identification mechanism 12 is mounted above the conveyor belt mechanism 11 and close to the material drop bin assembly 13; the material drop bin assembly 13 includes the above-mentioned material sorting device; the material sorting device is arranged adjacent to the outlet end of the conveyor belt mechanism 11; the electric control cabinet 14 is electrically connected to and controlled by the feed chute 10, the conveyor belt mechanism 11, the material identification mechanism 12 and the material drop bin assembly 13, respectively. The width of the conveyor belt in the conveyor belt mechanism 11 is 1950 mm; the effective width of the conveyor belt in the conveyor belt mechanism 11 is 1800 mm; the particle size of the ore that can be processed by the sorting equipment is 8 to 30 mm; the working speed of the conveyor belt in the conveyor belt mechanism 11 is 3.5 m / s.

[0071] The working steps of the sorting equipment are as follows: the material to be sorted falls onto the conveyor belt of the conveyor belt mechanism 11 through the feed chute 10, and the material is transported by the conveyor belt to the direction of the sorting device. The material to be sorted falls at the outlet end of the conveyor belt mechanism 11. The gas ejected by the sorting device at this time hits the falling material to be sorted, changing the falling trajectory of different types of materials to achieve sorting. During the working process, the feed chute 10, the conveyor belt mechanism 11, the material identification mechanism 12 and the material separation bin assembly 13 are controlled to stop by the electric control cabinet 14. When the material to be sorted is transported on the conveyor belt mechanism 11, it will pass through the material identification mechanism 12. The camera in the material identification mechanism 12 will take pictures and identify the material to be sorted, and then transmit the identification data to the electric control cabinet 14. Then the processing system in the electric control cabinet 14 will issue instructions to control the sorting device to spray.

[0072] like Figure 8 As shown, in this embodiment, the material identification mechanism 12 includes a fixed frame 121 and a plurality of XYR fine-tuning platforms 122, each of the XYR fine-tuning platforms 122 is installed with a camera 123, and all the XYR fine-tuning platforms 122 are installed on the fixed frame 121 through one or more lifting and adjusting components 124 in a manner that can synchronously adjust the height; the lifting and adjusting components 124 are installed with a plurality of horizontal slide rail mechanisms 125, and the XYR fine-tuning platforms 122 are installed on the horizontal slide rail mechanisms 125.

[0073] When in use, first adjust the lifting and adjusting component 124 to move the XYR fine-tuning platform 122 and the camera 123 thereon to a position with a suitable height; then adjust the XYR fine-tuning platform 122 so that the camera 123 on the XYR fine-tuning platform 122 can accurately focus on the position where the photo is required. By installing the camera 123 on the XYR fine-tuning platform 122, the XYR fine-tuning platform 122 is installed on the fixing frame 121 through the lifting and adjusting component 124 in a manner that can adjust the height synchronously; it is achieved that multiple camera positions can be adjusted in the height direction synchronously. Because the camera 123 is installed on the XYR fine-tuning platform 122, the cameras 123 at different positions can also be fine-tuned after the position adjustment in the height direction is completed, thereby ensuring the installation accuracy of the camera 123 position. The horizontal slide rail mechanism 125 can drive the XYR fine-tuning platform 122 and the camera 123 thereon to move in the horizontal direction, providing a horizontal adjustment dimension.

[0074] like Figure 8 and 9 As shown, in this embodiment, the lifting adjustment assembly 124 includes a lifting platform 41, a screw 42 and a threaded sleeve 43 matched with the screw 42, the screw 42 is fixedly connected to the lifting platform 41, and the threaded sleeve 43 is rotatably mounted on the fixing frame 121;

[0075] The lifting and adjusting components 124 are provided with more than two groups, and the threaded sleeves 43 of the two or more lifting and adjusting components 124 are connected through a synchronous driving mechanism 44 and driven to rotate synchronously by the synchronous driving mechanism 44;

[0076] The synchronous driving mechanism 44 includes a hand wheel 441 connected to the threaded sleeve 43 of any lifting and adjusting assembly, and the threaded sleeves 43 of each lifting and adjusting assembly are connected via a sprocket transmission mechanism 442.

[0077] By combining the screw and the lifting platform, the internal structure of the lifting component is simplified, and because the lifting platform is driven by the screw to perform lifting and lowering movements, the lifting process is stable and not easily affected by external vibrations. By setting up two sets of lifting and adjusting components, when the lifting platform is a large layout, it can also be lifted and lowered by two sets of lifting and adjusting components at the same time, avoiding the use of a single lifting component, which causes the lifting platform to be unevenly stressed during lifting, resulting in uneven lifting and inaccurate position adjustment accuracy due to excessive wear of the lifting component.

[0078] like Fig. 9 As shown, in this embodiment, one or more guide mechanisms 45 are provided between the fixing frame 121 and the lifting platform 41 for guiding the lifting movement of the lifting platform 41;

[0079] The guide mechanism 45 includes a guide column 451 and a sliding bearing 452 sleeved on the guide column 451, the guide column 451 is fixedly connected to the lifting platform 41, and the sliding bearing 452 is fixedly connected to the fixing frame 121;

[0080] The end of the guide column 451 away from the lifting platform 41 is mounted with a locking block 46 against the sliding bearing 452 .

[0081] Adding a guide mechanism can further regulate the movement path of the lifting platform during the lifting process and ensure the accuracy of the lifting adjustment. In this embodiment, the guide column 451 can extend the adjustment distance of the lifting and lowering after cooperating with the locking block 46, solving the problem that the existing camera position adjustment range is too narrow. It also avoids the difficulty of the long screw fixing method, and the vibration will cause shaking that is not conducive to the stability of the platform position.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
