In order to facilitate an understanding of the utility model, the utility model will be described more fully and in detail below with reference to the accompanying drawings and preferred embodiments, but the scope of the utility model is not limited to the specific embodiments below.

Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The use of the words "a" or "an" and the like in the description and claims of the present patent application do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

The embodiment provides a material separating device for solid material separation, as shown in fig. 1 and fig. 3, the material separating device comprises an integrated valve body 1, an air cavity 103 is arranged in the integrated valve body 1, an air nozzle 101 is arranged at one end of the integrated valve body 1, an air inlet 102 communicated with the air cavity 103 is arranged at the other end of the integrated valve body 1, and a material separating electromagnetic valve group 2 which is simultaneously connected with the air nozzle 101 and the air cavity 103 to control the size of air flow is further arranged on the integrated valve body 1; the method is characterized in that: divide material solenoid valve group 2 to be equipped with the multirow, and all locate on integrated valve body 1 and towards the one side of solid material whereabouts direction after being jetting.

When the material distributing device works, external high-pressure gas enters an air cavity 103 of the integrated valve body 1 through an air inlet 102, then enters a material distributing electromagnetic valve group 2 which is simultaneously connected with the air nozzle 101 and the air cavity 103, and finally high-pressure gas is sprayed out of the air nozzle 101 to hit materials falling on a front section station, so that the running track of the falling materials is changed to realize the separation of different materials; the material distributing electromagnetic valve group 2 can control the size and the on-off of air flow, and materials with different qualities can be sorted by controlling the material distributing electromagnetic valve group 2, so that the materials can be sorted into several types.

After the material-distributing electromagnetic valve group 2 is used for a long period of time, the material-distributing electromagnetic valve group 2 is inevitably damaged due to various reasons, and if the material-distributing electromagnetic valve group 2 is damaged in the working process, the material-distributing electromagnetic valve group needs to be maintained and replaced. In the prior art, two rows of material distributing electromagnetic valve groups 2 are respectively arranged on two sides of an integrated valve body 1, if the material distributing electromagnetic valves close to a front section station need to be replaced and maintained, the whole material distributing device needs to be detached from a sorting device, and then the electromagnetic valves on the material distributing device are maintained, so that the maintenance operation mode consumes time and is difficult to maintain and operate.

In the embodiment, the material distributing electromagnetic valve group 2 is divided into the first material distributing electromagnetic valve group 201 and the second material distributing electromagnetic valve group 202 which are arranged on the integrated valve body 1 at the side far away from the front end station. When the material distributing electromagnetic valve group 2 is damaged and needs to be replaced, only the material distributing electromagnetic valve group 2 concentrated on one side needs to be repaired and replaced on the sorting equipment, and the material distributing device does not need to be integrally detached from the sorting equipment. So that the repairing and the replacement can be conveniently carried out when the space of the arrangement area of the material distributing device in the sorting equipment is small. The air nozzle 101 on the integrated valve body 1 can be closer to the front section station during working, and air injection separation is facilitated. Because the sorted materials contain water and other factors, the farther the air nozzle 101 is away from the discharge port of the front section station, the more unstable the trajectory of the downward movement of the materials is, and the larger the influence on the sorting effect is; therefore, the material distributing electromagnetic valve group 2 needs to be close to the discharge end of the front section station as much as possible.

Because in the sorting process of the same batch of materials, the relative position angle between the air nozzle 101 of the material separating device and the discharge port of the front section station is selected through debugging, the selected position is ensured not to be changed when the material separating electromagnetic valve group 2 is maintained and replaced, the setting mode of the material separating electromagnetic valve group which does not need to be disassembled and changed is better operated, and the sorting precision after maintenance is not influenced.

Through set up multirow branch material solenoid valve group 2 on integrated valve body 1 for divide material solenoid valve group 2 can control more air nozzles 101, therefore the range density of air nozzles 101 on integrated valve body 1 also will be higher, and centre-to-centre spacing between the air nozzles 101 is littleer, and the material granularity that the adaptation was handled is littleer, selects separately more accurate and application scope wider. The center distance between the air nozzles 101 is 6mm, the minimum distance can be suitable for ore particles with the particle size of 6mm, and meanwhile, the air blowing accuracy of the air nozzles 101 is improved. The removing force of the gas sprayed by the air nozzle 101 is larger, and the air nozzle is more suitable for removing materials with large specific gravity.

As shown in fig. 1, in this embodiment, an air passage communicating an air nozzle 101, a material-separating solenoid valve set 2, and an air cavity 103 is provided in the integrated valve body 1, and the lengths of the air passages are all kept consistent.

The total length of the air inlet channel and the air outlet channel of each row of distributing electromagnetic valve groups is ensured to be consistent, so that the pressure of air flow discharged from the air nozzle after passing through the air inlet channel and the air outlet channel from the air cavity is consistent. The air inlet channel 104 and the air outlet channel 105 are connected with the material-distributing electromagnetic valve group 2 in a way that the total path is shortest by adopting a straight line or a broken line, because the shorter the total path is, the more beneficial the air blowing effect, the air blowing time and the excess pressure release are. Through the design to the inside gas circuit pipeline of integrated valve body 1 for integrated valve body is at during operation spun gas stability higher, and the sorting precision is higher.

As shown in fig. 1, in this embodiment, the material distribution solenoid valve group 2 is provided with two rows, including a first material distribution solenoid valve group 201 and a second material distribution solenoid valve group 202, and an included angle between a mounting base surface where the first material distribution solenoid valve group 201 is located and a mounting base surface where the second material distribution solenoid valve group 202 is located is 124 degrees. In the case of the angle design scheme, the total lengths of the air inlet channel and the air outlet channel of each row of material distributing electromagnetic valve banks are consistent, the total path of the air inlet channel 104 and the air outlet channel 105 is shortest, and at the moment, the two rows of material distributing electromagnetic valve banks are both suitable for being operated by maintenance personnel for tightening or loosening screws on the sorting equipment.

As shown in fig. 1, in the present embodiment, the air passage includes an air inlet passage 104 communicating the material-separating solenoid valve group 2 and the air chamber 103, and an air outlet passage 105 communicating the material-separating solenoid valve group 2 and the air nozzle 101; the air inlet channel 104 is basically vertical to the mounting base surface of the material distribution electromagnetic valve group 2; the air outlet channel 105 comprises a connecting air channel 1051 and a vertical air channel 1053, and the vertical air channel 1053 is communicated with the air nozzle 101 and is positioned on the central axis surface 1052 of the integrated valve body 1; the connecting air channel 1051 is connected with the vertical air channel 1053 and the material separating electromagnetic valve group 2, and the connecting air channel 1051 is basically parallel to the air inlet channel 104.

The air passage structure is an adaptive design after the position of the electromagnetic valve bank for distributing materials on the integrated valve body is changed. By the arrangement of the air passage position, the air passage of the material distributing electromagnetic valve is convenient to process, only linear drilling operation is needed to complete the processing, and the processing precision of a workpiece is easy to control; secondly, the relative position of the air passage structure and the material distributing electromagnetic valve ensures that the air passage sealing performance is good between high assembly precision of the material distributing electromagnetic valve and the integrated valve body during assembly.

As shown in fig. 1, in this embodiment, the vertical air channels 1053 corresponding to each material separating solenoid valve in the material separating solenoid valve group 2 have the same length, and the sum of the lengths of the air inlet channel 104 and the connecting air channel 1051 corresponding to each material separating solenoid valve is also substantially the same. The air passage design with the structure is adopted to keep the total length of the air passages passing through each material distributing electromagnetic 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 is equal when the gas is sprayed out after passing through the air passages.

As shown in fig. 1, 2 and 3, in the present embodiment, the integrated valve body 1 is provided with an evacuation assembly 3 communicating with the air cavity 103 or the air inlet 102; the evacuation component 3 comprises an evacuation electromagnetic valve 301 and an evacuation hole 302 formed in the side wall of the integrated valve body 1, and the evacuation electromagnetic valve 301 is mounted on the evacuation hole 302; the aperture of the drain hole 302 is larger than that of the gas inlet channel 104.

The operating principle of the dredging 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 inlet air enters the air cavity 103 from the air inlet 102 and then enters the air inlet channel 104 inside the material-separating electromagnetic valve group 2 from the air cavity 103, if impurities are carried in the inlet air, the inlet air is easy to deposit at the channel opening between the air cavity 103 and the air inlet channel 104; the gas inlet passage 104 is clogged when the impurity content is large. To avoid this, the impurity removal process may be performed on the impurities in the air cavity 103 by timing. The impurity removing treatment is carried out by opening the evacuation solenoid valve 301 of the evacuation hole 302 and discharging the impurities through the evacuation hole 302 by using the air pressure in the air chamber 103. Since the aperture of the evacuation hole 302 is larger than that of the air inlet passage 104, when the evacuation solenoid valve 301 is opened, the air in the air chamber 103 is preferentially discharged from the evacuation hole 302 without entering the air inlet passage 104. Because the gas entering the gas distributing device before the gas spraying and distributing operation is started is high-pressure gas, if liquid impurities such as water, oil and the like are left in the gas cavity 103, the liquid impurities are vaporized under the pressure action of the high-pressure gas; at this time, the evacuation solenoid valve 301 of the evacuation hole 302 is opened to discharge the gas, thereby performing a function of discharging the liquid impurities.

As shown in fig. 1, in this embodiment, the integrated valve body 1 includes a top cone 106 and a bottom rectangular body 107, which are connected to each other, and a sealing gasket 4 is disposed around the outlet channel 105 at the connection position of the two. The cone 106 is an integrated structural member and is provided with the air outlet channel 105, air flow is ejected from the air inlet 102 on the cone 106 through the air outlet channel 105, the problem that the direction of ejected air flow is deviated due to poor sealing caused by air leakage caused by error easily generated during installation of a conventional multi-tube air tap is solved by adopting the design, and impurities such as dust and the like are prevented from entering the air cavity 103 inside the integrated valve body 1 from part of structure. The sealing washer 4 is provided to better ensure the air tightness between the cone 106 and the rectangular body 107.

As shown in fig. 2, in this embodiment, the air valve further includes a sealing cover 5, the integrated valve body 1 and the material-distributing electromagnetic valve group 2 are both fixed in the sealing cover 5, and an opening 501 is formed in the sealing cover 5 at a position corresponding to the air nozzle 101; the sealing cover body 5 is provided with a flow guide plate 502 extending out of the air nozzle 101 at the opening 501.

The sealing cover body is arranged to protect the integrated valve body 1 and the material distribution electromagnetic valve group 2 from being hit by materials and prevent impurities from entering the air cavity 103 in the integrated valve body 1. The opening 501 is used to discharge the gas discharged from the gas nozzle 101 to the outside of the sealed enclosure 5. In the material distribution process, the heavier solid material is easy to fall firstly, and if the falling material hits the air nozzle 101, the air nozzle 101 is damaged and impurities enter the air cavity 103 of the integrated valve body 1; the guide plate 502 extending out of the air nozzle 101 is arranged at the opening 501 of the sealing cover body 5, so that the guide plate 502 can guide the materials away from the upper part of the air nozzle 101 even if the materials falling too early are thrown to the position of the air nozzle 101; the material is prevented from directly hitting the air nozzle 101 and being accumulated at the position of the air nozzle 101. According to the specific situation of the materials to be sorted, a proper guide plate 502 with the thickness of 5mm is selected, so that normal air injection sorting of the material distribution device can be met, and the materials falling on the upper part of the air nozzle 101 can be guided away to the maximum extent.

As shown in fig. 5, in the present embodiment, the air conditioner further includes an air inlet duct 6 connected to the air inlet 102, and the air inlet duct 6 is provided with a filter assembly 7; the filter assembly 7 is a two-stage filter, wherein one stage is a dust filter 701 for filtering dust impurities in the intake air, and the other stage is a liquid filter 702 for filtering water and oil components in the intake air. Wherein a liquid filter 702 for filtering water and oil components in the intake air is adjacent to the intake port 102 of the integrated valve body 1.

Through set up filtering component 7 on inlet line 6, further make gaseous before the integrated valve body 1 of people obtains higher purity, avoid having impurity and harm integrated valve body 1 because of admitting air. Through setting up two kinds of filters that filter different impurity respectively, can have corresponding different impurity of filtration more, filter the validity better

As shown in fig. 4, in this embodiment, the valve further includes a frame 8, two ends of the integrated valve body 1 are mounted on the frame 8, and the frame 8 is further provided with a water spraying device 9 for cleaning the sealing cover 5. The water spraying device 9 is provided with two water spraying nozzles which are respectively arranged at two ends of the integrated valve body 1; the water spraying nozzles can spray water alternately at regular time. The dust adhered to the sealing cover body of the material distributing device can be washed down by arranging the cleaning device.

The purpose of providing the water spraying device 9 is: after the material distributing device works for a long time, the outer surface of the sealing cover body 5 of the material distributing device is inevitably adhered with dust of the sorted materials, and if the adhesion amount is too large, the normal rotation of the material distributing device can be influenced. The material separating device can accurately separate materials by changing the alignment direction of the nozzle 101 through rotating the position according to different conditions of the materials to be separated. Therefore, if the material distributing device can not normally rotate, the parabolic track which is supposed to change when the ores pass through the material distributing device can become abnormal, and the sorting effect of the material distributing device is reduced. The water spraying nozzles of the cleaning device 9 intermittently spray water in a staggered manner, so that materials adhered to the sealing cover body of the material distributing device are timely washed down to avoid the influence on the normal rotation of the material distributing device, and the stable operation of the material distributing device can be further ensured.
