The embodiment provides a solid material distribution device, as shown in fig. 2 to 4, which includes an integrated valve body 1, an air cavity 13 is arranged in the integrated valve body 1, an air nozzle 11 is arranged at one end of the integrated valve body 1, an air inlet 12 communicated with the air cavity 13 is arranged at the other end of the integrated valve body 1, and a distribution electromagnetic valve group 2 which is simultaneously connected with the air nozzle 11 and the air cavity 13 to control the size and the on-off of air flow is further installed on the integrated valve body 1; and a impurity removing mechanism 3 for removing impurities deposited in the air cavity 13 is arranged between the air cavity 13 and the air inlet 12 on the integrated valve body 1.

When the solid material distributing device works, external high-pressure gas enters an air cavity 13 of the integrated valve body 1 through an air inlet 12, then enters a distributing electromagnetic valve group 2 which is simultaneously connected with the air nozzle 11 and the air cavity 13, and finally the high-pressure gas is ejected from the air nozzle 11 to hit materials falling from 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.

To realize the sorting of the materials, it is necessary to ensure that the gas ejected from the gas nozzle 11 reaches the preset force and angle, however, if the gas path through which the gas flows in the integrated valve body 1 is blocked by impurities, the gas ejected from the gas nozzle 11 cannot reach the preset force and angle. However, when solid materials are sorted, a lot of impurities such as dust and the like are inevitably generated, and the impurities can easily enter the integrated valve body 1 through various conditions; and the air cavity 13 and the air inlet 12 are places where the impurities are easy to deposit, so that the impurity discharging mechanism 3 for cleaning the impurities deposited in the air cavity 13 is arranged between the air cavity 13 and the air inlet 12 on the integrated valve body 1 in the embodiment. Impurities in the air cavity 13 are cleaned frequently, so that the air channel blockage caused by too many impurities in the air cavity 13 is avoided, and the normal work of the solid material distribution device is guaranteed.

The impurity discharging mechanism 3 comprises an impurity discharging electromagnetic valve 31 and an impurity discharging hole 32 formed in the side wall of the integrated valve body 1, the impurity discharging hole 32 is communicated with the air cavity 13 and the air inlet 12, and the impurity discharging electromagnetic valve 31 is packaged at the impurity discharging hole 32. By forming the impurity discharging hole 32 on the side wall of the integrated valve body 1 and communicating the impurity discharging hole 32 with the air cavity 13 and the air inlet 12; so that the air chamber 13 and the air inlet 12, if foreign substances are present, can be discharged through the foreign substance discharge hole 32. When the trash removal operation is performed, the trash removal solenoid valve 31 is opened, and external air intake and air in the air chamber 13 are discharged through the trash discharge hole 32 communicating with the air chamber 13 and the air intake port 12. The operation of the impurity removing process is convenient and simple.

An exhaust air passage 14 for communicating the material distributing electromagnetic valve group 2 and the air nozzle 11 is arranged in the integrated valve body 1, an air inlet air passage 15 for communicating the material distributing electromagnetic valve group 2 and the air cavity 13 is also arranged in the integrated valve body 1, and the cavity diameter of the air cavity 13 is larger than the aperture of the air inlet air passage 15. The air inlet passage 15 and the air outlet passage 14 are air passages through which high-pressure air respectively flows when the solid material distributing device works, the diameter of the air cavity 13 is larger than the diameter of the air inlet passage 15, so that stable air pressure is always kept in the air cavity 13 when the solid material distributing device works, the air pressure of air flowing through the air inlet passage 15 and the air outlet passage 14 can be kept stable, the force and the angle of the air finally sprayed by the air nozzle 11 are kept stable, and the solid material distributing device can continuously and normally work.

The aperture of the impurity discharging hole 32 is larger than that of the air intake duct 15. The aperture of the impurity discharging hole 32 is set to be larger than that of the air inlet passage 15 because if the aperture of the impurity discharging hole 32 is larger than that of the air inlet passage 15, when the impurity discharging electromagnetic valve 31 is opened, the amount of gas flowing out of the impurity discharging hole 32 is larger than that of the air inlet passage 15; therefore, the gas in the gas cavity 13 can be preferentially discharged from the impurity discharge holes 32 and can not enter the gas inlet passage 15; the normal and effective operation of impurity removal is guaranteed.

The operating principle of the impurity removing mechanism 3 is as follows: because the cavity diameter of the air cavity 13 is larger than the aperture of the air inlet air passage 15, when the inlet air enters the air cavity 13 from the air inlet 12 and then enters the air inlet air passage 15 inside the material-distributing electromagnetic valve group 2 from the air cavity 13, if impurities are carried in the inlet air, the inlet air is easy to deposit at the channel opening between the air cavity 13 and the air inlet air passage 15; when the impurity content is high, the intake air duct 15 is clogged. To avoid this, the impurity removal process may be performed on the impurities in the air chamber 13 at regular times. The impurity removing treatment is performed by opening the impurity removing solenoid valve 31 of the impurity removing hole 32 and discharging the impurities through the gas injection of the impurity removing hole 32 by using the gas pressure in the gas chamber 13. Since the aperture of the exhaust hole 32 is larger than that of the intake air passage 15, when the exhaust solenoid valve 31 is opened, the gas in the air chamber 13 is preferentially discharged from the exhaust hole 32 without entering the intake air passage 15. Because the gas entering the material separating device before the gas injection and material separation work is high-pressure gas, if liquid impurities such as water, oil and the like are left in the gas cavity 13, the gas can be vaporized under the pressure action of the high-pressure gas; at this time, the impurity discharge solenoid valve 31 of the impurity discharge hole 32 is opened to discharge the gas, thereby performing a function of discharging the liquid impurities.

As shown in fig. 4, in the present embodiment, the integrated valve body 1 includes a top cone 16 and a bottom rectangular body 17, which are connected to each other, and a sealing gasket 4 is disposed around the exhaust air duct 14 at the connection position of the two.

The sealing gasket 4 is provided to better ensure the air tightness between the cone 16 and the rectangular body 17.

As shown in fig. 3, in this embodiment, the solid material distribution device further includes a sealing cover 5, the integrated valve body 1 and the distribution solenoid valve set 2 are both fixed in the sealing cover 5, and an opening 51 is provided at a position of the sealing cover 5 corresponding to the air nozzle 11. 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 13 in the integrated valve body 1. The opening 51 is used to discharge the gas discharged from the gas nozzle 11 to the outside of the sealed enclosure 5.

As shown in fig. 3, in the present embodiment, the sealing enclosure 5 is provided with a baffle 52 extending out of the air nozzle 11 at the opening 51.

In the material distributing process, the heavier solid materials are easy to fall firstly, and if the materials falling firstly hit the air nozzle 11, the air nozzle 11 is damaged, and impurities enter the air cavity 13 of the integrated valve body 1; the guide plate 52 extending out of the air nozzle 11 is arranged at the opening 51 of the sealing cover body 5, so that the guide plate 52 can guide the materials away from the upper part of the air nozzle 11 even if the materials falling prematurely are thrown to the position of the air nozzle 11; the material is prevented from directly hitting the air nozzle 11 and being accumulated at the position of the air nozzle 11. According to the specific situation of the materials to be sorted, a proper guide plate 52 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 11 can be guided away to the maximum extent.

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.

The filter unit 7 is a two-stage filter, in which one stage is a dust filter 71 for filtering dust impurities in the intake air, and the other stage is a liquid filter 72 for filtering water and oil components in the intake air. Wherein a liquid filter 72 for filtering water and oil components in the intake air is adjacent to the intake port 12 of the integrated valve body 1. Through setting up two kinds of filters that filter different impurity respectively, can have more pointed different impurity of filtration, filter the validity better.
