The interior top surface of casing 1 rotates and is connected with pivot 8, and pivot 8 tip is connected with the output of peripheral hardware motor, and rotor 9, rotor 10 have down been connected gradually from last to the side of pivot 8, and the feed piece 7 that is used for adding the material to casing 1 inside is installed on the upper portion of casing 1, and the top of casing 1 is equipped with the controller, and the side of ring pipe 48 has the relief valve through the pipe connection, and when the inside atmospheric pressure of ring pipe 48 exceeded the threshold value of predetermineeing, the atmospheric pressure balance of guaranteeing the inside atmospheric pressure of ring pipe 48 was discharged through the relief valve, guarantees the normal work of clearance subassembly 4.
When powder selecting work is needed, materials are added into the shell 1 through the feeding piece 7, the peripheral motor drives the rotating shaft 8 to rotate so as to drive the lower rotor 9, the material spreading disc and the lower rotor 10 to synchronously rotate, circulating air generated by the fan 2 tangentially flows into the shell 1 through the air inlet pipe 3, is subjected to primary sorting under the action of the lower rotor 10, and is gradually moved to the position of the conical material distributing hopper 6 under the action of air flow, and is screened by the conical material distributing hopper 6, so that the powder selecting effect is achieved, the aperture size of the conical material distributing hopper 6 can be selected and adjusted according to the needs, the particle size of the powdery materials is controlled, the accurate control of the particle size of products can be realized by selecting the proper conical material distributing hopper 6, and the requirements of different applications are met.
Referring to fig. 2, the ventilation mechanism includes two air pressure sensors 49, the two air pressure sensors 49 are respectively mounted on the upper portion of the housing 1 and the lower portion of the housing 1 corresponding to the position of the conical distribution hopper 6, the air inlet pipe 3 is mounted with a first control valve 410, the side surface of the air inlet pipe 3 is connected with a second control valve 411 through a first connecting pipe 412, the first connecting pipe 412 is located on the upper portion of the first control valve 410, the air inlet pipe 3 is connected with the annular pipe 48 through the first connecting pipe 412, and when the air pressure exceeds a threshold value, the second control valve 411 controls the air flow blown out by the fan 2 to enter the inside of the first connecting pipe 412.
Furthermore, if the materials contain higher moisture along with the sieving operation, the powder materials are easy to agglomerate, and the filter screen inside the powder concentrator is blocked. If the adhesive is strong, the adhesive is easy to adhere to the inner screen of the powder concentrator, and the filter screen is gradually blocked.
When the filtering holes on the conical distribution hopper 6 are blocked by the material, the material cannot pass smoothly, so that gas is accumulated in the machine, and a local high-pressure area is formed near the conical distribution hopper 6. When the powder concentrator is blocked, the air pressure in the machine can be reduced, and the air cannot smoothly pass through the blocked area, which is common knowledge in the prior art, so that details are not repeated herein, and by arranging two air pressure sensors 49 which are sequentially arranged at the upper part of the shell 1 and at the lower part of the shell 1 and correspond to the position of the conical material distributing hopper 6, when the air pressure in the shell 1 is increased or reduced, the air pressure sensors 49 can timely identify the air pressure change in the shell 1; it is noted that during use, the air pressure sensor 49 is connected to the controller, typically using a cable. The controller may be an automatic control system such as a PLC or DCS, or may be a simple logic controller. Setting control parameters: parameters of the controller, such as the pressure ranges of opening and closing of the valve, the opening and closing time, etc., are set according to the specific application requirements. Monitoring the change of air pressure: when the pressure in the pipe changes, the air pressure sensor 49 detects a corresponding signal and transmits the signal to the controller. And (3) controlling the valve to switch: the valve is opened or closed according to the instruction of the controller; the conventional technical means in the prior art are not described herein.
Further, in the initial state, the first control valve 410 is in an open state, the second control valve 411 is in a closed state, when the air pressure variation in the casing 1 exceeds the preset range, the controller closes the first control valve 410 and opens the second control valve 411, at this time, the air flow generated by the fan 2 does not enter the casing 1 for powder selecting, the air flow generated by the fan 2 enters the annular tube 48 through the second control valve 411 and the first connecting tube 412, and then sequentially enters the first piston cylinders 41 through the plurality of communicating tubes 43 on the side surface of the annular tube 48.
It should be noted that, since the elastic force of the elastic connection between the first piston rod 42 and the first piston cylinder 41 is smaller than the elastic force of the elastic connection between the annular connection plate 413 and the first piston rod 42, as the amount of the gas entering the interior of the first piston cylinder 41 gradually increases, the gas extrusion force gradually increases, and the gas extrusion force gradually makes the first piston rod 42 drive the sealing cover 45 to move towards the direction approaching the tapered dispensing hopper 6 against the elastic force between the first piston cylinder 41, and the inner surface of the sealing cover 45 is adapted to the outer surface of the tapered dispensing hopper 6 until each sealing cover 45 is tightly attached to the outer side of the tapered dispensing hopper 6.
Referring to fig. 4 to 5 and 7, the communication member includes an annular connection plate 413 elastically connected to an end portion of the first piston rod 42, a connection hole 415 is opened at an inner side surface of the first piston rod 42, a sealing rod 414 is connected to a side surface of the annular connection plate 413, and an end portion of the sealing rod 414 extends to an inside of the connection hole 415; the inner diameter of the connection hole 415 is smaller than the inner diameter of the first piston rod 42.
At this time, the first piston rod 42 is not moved any more, as the gas amount in the first piston cylinder 41 continues to increase, the gas extrusion force gradually makes the sealing rod 414 drive the annular connecting plate 413 to move towards the direction close to the interior of the first piston rod 42 against the elastic force between the annular connecting plate 413 and the first piston rod 42, until the end of the sealing rod 414 enters into the interior of the first piston rod 42, since the inner diameter of the connecting hole 415 is smaller than that of the first piston rod 42, the outer diameter of the end of the sealing rod 414 is the same as that of the connecting hole 415, at this time, a gap is gradually generated between the end of the sealing rod 414 and the first piston rod 42, the gas in the first piston cylinder 41 gradually enters into the interior of the first piston rod 42 through the gap, then enters into the sealing cover 45 through the through hole 46 into the interior of the sealing groove 47 after being tightly attached to the tapered dispensing hopper 6, and the gas amount entering into the interior of the sealing groove 47 is larger than the gas amount discharged through the filter hole on the tapered dispensing hopper 6 through the through hole on the tapered dispensing hopper 6, which it is worth noting that the gas discharged from the hopper 6 is not blocked by the filter hole on the tapered dispensing hopper 6 in the above description.
It is worth noting that, by setting the elastic force of the elastic connection between the first piston rod 42 and the first piston cylinder 41 to be smaller than the elastic force of the elastic connection between the annular connection plate 413 and the first piston rod 42, it is ensured that after the sealing cover 45 abuts against the conical distribution hopper 6, the gas inside the first piston cylinder 41 can enter into the sealing groove 47 to perform cleaning work, so that the sealing cover 45 is prevented from abutting against the conical distribution hopper 6, the gas inside the first piston cylinder 41 is discharged through the sealing groove 47, the air pressure inside the first piston cylinder 41 is reduced, the sealing cover 45 cannot normally abut against the conical distribution hopper 6, and the subsequent cleaning work is ensured to be performed normally.
Further, because the filter hole on the conical distribution hopper 6 is blocked, the gas entering the inside of the seal groove 47 cannot be timely discharged through the filter hole on the conical distribution hopper 6, the gas quantity inside the seal groove 47 is gradually increased, the gas inside the seal groove 47 cannot be timely discharged, the gas enters the inside of the blocked filter hole to extrude and punch the materials, the extrusion force enables the materials inside the filter hole on the conical distribution hopper 6 to move towards the direction close to the inside of the conical distribution hopper 6 until the materials inside the blocked filter hole enter the inside of the conical distribution hopper 6, namely, the cleaning work of the blocked filter hole on the conical distribution hopper 6 is completed, and the more the filter hole on the conical distribution hopper 6 is blocked, the smaller the gas quantity is timely discharged, the faster the gas pressure inside the seal groove 47 is, the impact force of the gas on the materials inside each filter hole is guaranteed, and the logistics blocked inside the filter hole is guaranteed to be cleaned rapidly when the blocking number of the filter hole on the conical distribution hopper 6 is more. The inner diameter of the through hole 46 is larger than that of the filtering hole on the conical distribution hopper 6, so that the gas impact force is ensured;
After the cleaning of the filtering holes on the conical distribution hopper 6 is completed, the second control valve 411 is closed by the controller, the first control valve 410 is opened, at the moment, the gas generated by the fan 2 enters into the shell 1 to perform powder selecting work, meanwhile, the pressure relief valve on the annular pipe 48 is opened by the controller, the gas in the annular pipe 48 is discharged, the extrusion force of the gas on the sealing rod 414 and the first piston rod 42 is sequentially disappeared, the elastic force of elastic deformation between the first piston rod 42 and the first piston cylinder 41 is restored to drive the first piston rod 42 to return to the position in the initial state, the first piston rod 42 drives the sealing cover 45 to return to the position in the initial state, the blocking of the conical distribution hopper 6 is canceled, the normal proceeding of the filtering work of the conical distribution hopper 6 is ensured, the elastic force of elastic restoring between the annular connecting plate 413 and the first piston rod 42 drives the sealing rod 414 to return to the position in the initial state, ensuring the normal operation of the next cleaning work, further comparing with the prior art that the blocked filter holes on the filter screen are cleaned manually by using special tools such as a pneumatic hook, a steel wire rope and the like or the filter screen is cleaned by taking out the filter screen and using clear water or special cleaning agents, in the using process, the application judges the blocking condition of the filter holes on the conical distribution hopper 6 through the air pressure change of a plurality of positions in the shell 1, if the filter holes of the conical distribution hopper 6 are blocked seriously, the air pressure close to the position of the conical distribution hopper 6 is rapidly increased, the air pressure far from the position of the conical distribution hopper 6 is reduced, the air pressure change is transmitted to the controller by the air pressure sensor 49, the controller enables the cleaning component 4 to start working, and the blocked filter holes on the conical distribution hopper 6 are cleaned by the air pressure impact force when the cleaning component 4 works, the filter holes blocked on the conical distribution hopper 6 can be cleaned rapidly and largely, the operation effect and the efficiency of the powder concentrator are guaranteed, and meanwhile, the possibility of damage of the powder concentrator is reduced.
Referring to fig. 4 and 6, the adjusting member includes two second piston barrels 416, the second piston barrels 416 are connected to the inner top surface and the inner bottom surface of the sealing groove 47 at positions corresponding to the through holes 46, a second piston rod 417 is elastically and slidably connected to the inside of the second piston barrels 416, and one end of the second piston rod 417 extends through the second piston barrels 416 to a position close to the through holes 46 and is connected to a sealing block 418.
