DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 13 As shown, the technical solution adopted by the present invention is as follows: a feeding device for ammonium perchlorate production, comprising a feeding box 1 and an adsorption assembly. A feeding pipe 2 is installed at the lower end of the feeding box 1, and a valve 3 is installed on the feeding pipe 2. When the valve 3 is opened, the material in the feeding box 1 flows out through the feeding pipe 2.

[0023] The upper end of the feeding box 1 is open. Two guide plates are symmetrically mounted on the upper end of the feeding box 1. Figure 3 As shown, the lower end of the guide plate is rotatably connected to the feed box 1 via a rotating shaft 9, and a first torsion spring is sleeved on the rotating shaft 9, one end of the first torsion spring is fixedly connected to the feed box 1, and the other end of the first torsion spring is fixedly connected to the first guide plate 8.

[0024] The upper end of the guide plate is provided with a second inclined surface. In a natural state, under the action of the first torsion spring, the upper ends of the two guide plates are in contact with each other through the second inclined surface. The upper end of the feeding box 1 and the position corresponding to the guide plate are provided with a first inclined surface. When the feeding box 1 is opened, the guide plate abuts against the first inclined surface.

[0025] The upper end of the guide plate is provided with a ventilating hole 29, and the outer side of the guide plate is provided with an air pipe 7 which is communicated with the ventilating hole 29. A driving assembly for inflating air into the air pipe 7 and extracting air from the air pipe 7 is installed on the feeding box 1.

[0026] The driving assembly includes a fan 4 and a telescopic member. The telescopic member includes a sleeve 5 and a connecting pipe 6, one end of the connecting pipe 6 is connected to the air pipe 7, and the other end of the connecting pipe 6 is slidably arranged in the sleeve 5, and the sleeve 5 is connected to the fan 4.

[0027] An adsorption component is disposed in each ventilation hole 29 .

[0028] The adsorption assembly includes a first mounting frame 11, a second mounting frame 12 and a filter cloth 18. One end of the first mounting frame 11 is rotatably connected to the inner wall of the ventilation hole 29 through a first shaft rod, the other end of the first mounting frame 11 is rotatably connected to one end of the second mounting frame 12 through a second shaft rod, and the other end of the second mounting frame 12 is rotatably connected to a slide plate 13 through a third shaft rod. A first chute 28 is provided on the inner wall of the ventilation hole 29, and the slide plate 13 is slidably arranged in the first chute 28. A first spring 20 is fixedly connected between the slide plate 13 and the end wall of the first chute 28. Filter cloth 18 is installed on one side of the first mounting frame 11 and the second mounting frame 12 close to the feeding box 1.

[0029] A limiting member is provided between the first installation frame 11 and the second installation frame 12. Fig.10 As shown, the limiting member includes a first slider 26. The first mounting frame 11 is fixedly connected to the second shaft rod, the second shaft rod is rotatably connected to the second mounting frame 12, the second mounting frame 12 is provided with an arc groove 27, the first slider 26 is slidably arranged in the arc groove 27, and the first slider 26 is fixedly connected to the second shaft rod. The first shaft rod, the second shaft rod, and the third shaft rod are all parallel to the rotating shaft 9.

[0030] The air pipe 7 is evacuated. Since the filter cloth 18 has a certain resistance to air, under the suction of the air pipe 7, the first mounting frame 11 rotates around the first shaft rod toward the direction close to the air pipe 7, and the second mounting frame 12 rotates around the third shaft rod toward the direction close to the air pipe 7. At the same time, the second mounting frame 12 rotates around the second shaft rod, and the first slider 26 slides in the arc groove 27. When the first slider 26 abuts against one end of the arc groove 27, the first mounting frame 11 and the second mounting frame 12 cannot continue to rotate. At the same time, the guide plate overcomes the elastic force of the first torsion spring and rotates outward until the guide plate abuts against the first inclined surface. The upper end of the feeding box 1 is opened, and materials can be put into the feeding box 1. The powder generated during the material feeding process is adsorbed onto the filter cloth 18.

[0031] When the feeding of materials is completed and the upper end of the feeding box 1 needs to be closed, the air pumping of the air pipe 7 is stopped, and under the action of the first torsion spring, the guide plate rotates around the rotating shaft 9, and the two guide plates approach each other until the two second inclined surfaces abut against each other. The upper end of the feeding box 1 is closed.

[0032] Then, the air is inflated into the air pipe 7, and the air blows toward the first mounting frame 11 and the second mounting frame 12, blowing the material powder adhered to the filter cloth 18 into the feeding box 1. At the same time, since the filter cloth 18 has a certain resistance, the air blows the first mounting frame 11 and the second mounting frame 12. The first mounting frame 11 rotates away from the air pipe 7 around the first shaft, and the second mounting frame 12 rotates away from the air pipe 7 around the third shaft. At the same time, the second mounting frame 12 rotates around the second shaft, and the first slider 26 slides in the arc groove 27. The slide plate 13 overcomes the elastic force of the first spring 20 and moves into the first slide groove 28.

[0033] When the first mounting frame 11, the second mounting frame 12 and the slide plate 13 are in the same straight line, the first mounting frame 11 and the second mounting frame 12 continue to rotate in the direction away from the air pipe 7 under the blowing of the gas, and at the same time, the first spring 20 pushes the slide plate 13, so that the slide plate 13 quickly slides out of the first slide groove 28, and the slide plate 13 pushes the second mounting frame 12 to quickly rotate around the third shaft rod, so that the first mounting frame 11 quickly rotates around the first shaft rod. The first slider 26 slides quickly in the arc groove 27, so that the first slider 26 quickly hits the end of the arc groove 27, so that the first mounting frame 11 and the second mounting frame 12 vibrate, which is conducive to shaking off the material powder adhered to the filter cloth 18.

[0034] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13As shown, a rotating plate 14 is provided on the first installation frame 11 and the second installation frame 12 on the side facing away from the filter cloth 18. Both ends of the rotating plate 14 are fixedly connected with a fourth shaft rod, and the fourth shaft rod is rotatably connected to the first installation frame 11 or the second installation frame 12. A second torsion spring is sleeved on the fourth shaft rod, one end of the second torsion spring is fixedly connected to the rotating plate 14, and the other end of the second torsion spring is fixedly connected to the first installation frame 11 or the second installation frame 12. The fourth shaft rod is parallel to the second shaft rod.

[0035] Under the action of the second torsion spring, the rotating plate 14 is parallel to the filter cloth 18, and the filter cloth 18 is blocked by multiple rotating plates 14, the first mounting frame 11 and the second mounting frame 12 are blocked, and the ventilation hole 29 is closed. When the rotating plate 14 is perpendicular to the filter cloth 18, the first mounting frame 11 and the second mounting frame 12 are opened, and the ventilation hole 29 is opened. The first mounting frame 11 and the second mounting frame 12 are in sealed sliding contact, and the first mounting frame 11, the second mounting frame 12 and the inner wall of the ventilation hole 29 are in sealed sliding contact.

[0036] A connecting plate 15 is provided at both ends of the first installation frame 11 and the second installation frame 12. The rotating plate 14 and the corresponding connecting plate 15 are rotatably connected through a fifth shaft rod. The fifth shaft rod is parallel to the fourth shaft rod. The connecting plate 15 is between the rotating plate 14 and the filter cloth 18. The connecting plate 15 is fixedly connected with a first pull rope 16.

[0037] Both ends of the first mounting frame 11 and the second mounting frame 12 are fixedly connected with a fixing block 17. The first mounting frame 11 and the second mounting frame 12 are both provided with a first threading channel. The first pull rope 16 on the first mounting frame 11 slides through the first threading channel on the first mounting frame 11 and then extends to the outside and is fixedly connected to the fixing block 17 on the second mounting frame 12. The first pull rope 16 on the second mounting frame 12 slides through the first threading channel on the second mounting frame 12 and then extends to the outside and is fixedly connected to the fixing block 17 on the first mounting frame 11. When the first mounting frame 11 and the second mounting frame 12 are both inclined toward the side close to the trachea 7 and the first slider 26 abuts against one end of the arc groove 27, the first pull rope 16 is in a taut state, and under the pulling action of the first pull rope 16, the connecting plate 15 is away from the fourth shaft rod, so that the rotating plate 14 is in a state perpendicular to the filter cloth 18, and the ventilation hole 29 is opened.

[0038] When the first installation frame 11 and the second installation frame 12 are both tilted in a direction away from the air pipe 7, the first pull rope 16 is in a relaxed state, and under the action of the second torsion spring, the rotating plate 14 is parallel to the filter cloth 18. On the first installation frame 11, the ends of adjacent rotating plates 14 contact each other, and the rotating plates 14 at both ends of the first installation frame 11 contact the inner wall of the first installation frame 11, and multiple rotating plates 14 block the first installation frame 11. On the second installation frame 12, the ends of adjacent rotating plates 14 contact each other, and the rotating plates 14 at both ends of the second installation frame 12 contact the inner wall of the second installation frame 12, and multiple rotating plates 14 block the second installation frame 12.

[0039] For the convenience of description, the two material guide plates are respectively defined as a first material guide plate 8 and a second material guide plate 10 .

[0040] A second slide groove 22 is provided at the upper end of the first guide plate 8, and a clamping plate 23 is slidably provided in the second slide groove 22. A second spring 24 is fixedly connected between the clamping plate 23 and the end wall of the second slide groove 22. A clamping groove 25 cooperating with the clamping plate 23 is provided on the second guide plate 10.

[0041] The second slider 21 is fixedly connected to the clamping plate 23, and a limiting groove is provided on the inner wall of the second slide groove 22, and the second slider 21 is slidably arranged in the limiting groove. A second threading channel is provided on the first material guide plate 8. The second threading channel connects the limiting groove and the first slide groove 28. The second slider 21 is fixedly connected to the second pull rope 19, and one end of the second pull rope 19 slides through the second threading channel and is fixedly connected to the slide plate 13.

[0042] When the slide plate 13 moves out of the first slide groove 28 , the slide plate 13 pulls the clamping plate 23 to move out of the second slide groove 22 through the second pull rope 19 , so that the clamping plate 23 is inserted into the clamping groove 25 .

[0043] When the first installation frame 11 and the second installation frame 12 are both inclined toward the direction close to the air pipe 7 , under the action of the second spring 24 , the clamping plate 23 is located in the second sliding groove 22 .

[0044] Working principle: Initially, the upper end of the feeding box 1 is in a closed state, the upper ends of the first material guide plate 8 and the second material guide plate 10 are pressed against each other, and the clamping plate 23 is clamped into the clamping groove 25. The first mounting frame 11 and the second mounting frame 12 are both inclined away from the air pipe 7. The rotating plate 14 is parallel to the filter cloth 18, and the ventilation hole 29 is closed.

[0045] The fan 4 is started to exhaust air from the air pipe 7, so that the first mounting frame 11 rotates around the first shaft toward the air pipe 7, the second mounting frame 12 rotates around the third shaft toward the air pipe 7, and the second mounting frame 12 rotates around the second shaft. The first slider 26 slides in the arc groove 27 until the first slider 26 abuts against the end of the arc groove 27, and the first mounting frame 11 and the second mounting frame 12 cannot continue to rotate.

[0046] When the first mounting frame 11 and the second mounting frame 12 rotate toward the direction close to the air pipe 7, the second mounting frame 12 pushes the slide plate 13 to slide into the first slide groove 28, the second pull rope 19 becomes loose, and under the action of the second spring 24, the clamping plate 23 slides into the second slide groove 22, so that the second slide groove 22 is disengaged from the clamping groove 25. Then, the restriction of the first guide plate 8 and the second guide plate 10 is released.

[0047] When the first mounting frame 11 and the second mounting frame 12 rotate toward the direction close to the air pipe 7, the first pull rope 16 is gradually tightened, and the first pull rope 16 pulls the connecting plate 15 to move toward the direction close to the filter cloth 18, and the connecting plate 15 drives the rotating plate 14 to change to a state perpendicular to the filter cloth 18 until the rotating plate 14 is perpendicular to the filter cloth 18, the first mounting frame 11 and the second mounting frame 12 are opened, and the ventilation hole 29 is opened.

[0048] Under the suction of the air pipe 7, the first guide plate 8 and the second guide plate 10 overcome the elastic force of the first torsion spring and rotate outward, so that the first guide plate 8 and the second guide plate 10 are both against the corresponding first inclined planes. The upper end of the feeding box 1 is opened.

[0049] Materials are fed into the feeding box 1. Material powder generated during the feeding process is adsorbed onto the filter cloth 18, which prevents the material powder from flying outside the feeding box 1 and affecting the surrounding environment.

[0050] After the feeding is completed, the fan 4 is turned off. After the suction effect of the air pipe 7 is lost, the first guide plate 8 and the second guide plate 10 rotate under the action of the first torsion spring until the upper ends of the first guide plate 8 and the second guide plate 10 abut against each other, and the first guide plate 8 and the second guide plate 10 abut against each other through the second inclined surface. At this time, the clamping plate 23 is facing the clamping slot 25.

[0051] Then, the fan 4 is started to inflate the air pipe 7, and the air blows toward the first mounting frame 11 and the second mounting frame 12, blowing the material powder adhered to the filter cloth 18 into the feeding box 1. At the same time, due to the resistance of the filter cloth 18, the air blows the first mounting frame 11 and the second mounting frame 12, so that the first mounting frame 11 rotates away from the air pipe 7 around the first shaft, and the second mounting frame 12 rotates away from the air pipe 7 around the third shaft. At the same time, the second mounting frame 12 rotates around the second shaft, and the first slider 26 slides in the arc groove 27. The slide plate 13 overcomes the elastic force of the first spring 20 and moves into the first slide groove 28.

[0052] When the first mounting frame 11, the second mounting frame 12 and the slide plate 13 are in the same straight line, the first mounting frame 11 and the second mounting frame 12 continue to rotate in the direction away from the air pipe 7, and at the same time, the first spring 20 pushes the slide plate 13, so that the slide plate 13 quickly slides out of the first slide groove 28, and the slide plate 13 pushes the second mounting frame 12 to quickly rotate around the third shaft rod, so that the first mounting frame 11 quickly rotates around the first shaft rod. The first slider 26 slides quickly in the arc groove 27, so that the first slider 26 hits the end of the arc groove 27, so that the first mounting frame 11 and the second mounting frame 12 vibrate, which is conducive to shaking off the material powder adhered to the filter cloth 18.

[0053] When the slide plate 13 moves out of the first slide groove 28 , the slide plate 13 pulls the card plate 23 through the second pull rope 19 to move the card plate 23 outward, and then the card plate 23 is inserted into the card groove 25 , thereby limiting the first guide plate 8 and the second guide plate 10 .

[0054] When the first mounting frame 11 and the second mounting frame 12 are both rotated in the direction away from the air pipe 7, the first pull rope 16 gradually becomes loose. After the pulling force of the first pull rope 16 is lost, the rotating plate 14 moves to the vertical state under the action of the second torsion spring. Until the rotating plate 14 is parallel to the filter cloth 18, the first mounting frame 11 and the second mounting frame 12 are both blocked by the rotating plate 14, and the ventilation hole 29 is closed. At this time, one end of the connecting plate 15 abuts against the inner wall of the first mounting frame 11 or the second mounting frame 12, so that the rotating plate 14 cannot rotate further.

[0055] When the first material guide plate 8 and the second material guide plate 10 rotate around the corresponding rotation shaft 9 , the connecting pipe 6 slides in the sleeve 5 .

[0056] A method for using a feeding device for ammonium perchlorate production in the present invention comprises the following steps: S1, the air pipe 7 is evacuated to rotate the first mounting frame 11 and the second mounting frame 12 toward the air pipe 7, and the guide plate is rotated outward to open the feeding box 1 to facilitate feeding. At the same time, under the suction effect of the air pipe 7, the powder generated during the feeding process is adsorbed onto the filter cloth 18.

[0057] S2. After the feeding is completed, the air extraction of the air pipe 7 is stopped, and the guide plate rotates to close the upper end of the feeding box 1.

[0058] S3, inflate the air pipe 7 to blow off the material powder on the filter cloth 18, and at the same time, the first mounting frame 11 and the second mounting frame 12 rotate in a direction away from the air pipe 7. Under the action of the limiter, the first mounting frame 11 and the second mounting frame 12 vibrate to shake off the material powder on the filter cloth 18.

[0059] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
