DETAILED DESCRIPTION

[0021] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0022] The present application provides a fine powder collecting device for polyethylene wax powder preparation, mainly solves the problem that polyethylene wax powder is accumulated on the cloth bag, causing the cloth bag to be blocked, and affecting the subsequent separation efficiency of the cloth bag, and provides the following technical solutions, which will be described below in combination with Figures 1-9 Detailed description: A fine powder collecting device for polyethylene wax powder preparation, as shown in Figures 5-6 Fig. 1, comprises a shell 1, a cloth bag 2 is sleeved at the bottom of the shell 1, the cloth bag 2 is a dust filter cloth bag, the dust filter cloth bag can be divided into two types of inner filter type and outer filter type according to the filtering direction, the cloth bag 2 here is of the outer filter type, the bag opening of the cloth bag 2 faces upward, a square frame 5 is installed in the shell 1 above the bag opening, a beating plate 6 is installed on the outer side of the middle of the square frame 5, the beating plate 6 extends into the cloth bag 2, a movable mechanism for pushing the beating plate 6 to reciprocally beat the inner side of the cloth bag 2 is installed at the top of the square frame 5, a compression mechanism for realizing gas compression when the beating plate 6 is pushed is installed on the movable mechanism, and a blowing mechanism for blowing gas from the inner side of the cloth bag 2 to the outer side of the cloth bag 2 by using compressed gas is installed on the beating plate 6 in the cloth bag 2.

[0023] The cloth bag 2 is an outer filtering type dust filter cloth bag. When collecting fine powder, the gas containing polyethylene wax powder enters the inside of the cloth bag 2 from the outside of the cloth bag 2. The gas passes through the cloth bag 2, and the polyethylene wax powder is separated. When the polyethylene wax powder is separated in the cloth bag 2, if the gas or the cloth bag 2 or the internal space has a certain humidity, or the cloth bag 2 has static electricity, or for other reasons, the polyethylene wax powder adheres and gathers into blocks or patches on the outer surface of the cloth bag 2, causing the surface of the cloth bag 2 to be blocked, affecting the separation efficiency. When the separation efficiency is affected, the movable mechanism is started, and then the beating plate 6 reciprocatingly beats on the inside of the cloth bag 2. The beating plate 6 beats the inside of the cloth bag 2. When beating, the cloth bag 2 is vibrated and impacted. When the vibration and impact act on the adhered and gathered polyethylene wax powder blocks, the polyethylene wax powder blocks in the gathered state are scattered and fall. The dispersed polyethylene wax powder naturally falls under the action of gravity, thereby realizing cleaning of the polyethylene wax powder gathered on the outer surface of the cloth bag 2 and ensuring stable filtration of the cloth bag 2. When the movable mechanism drives the beating plate 6 to reciprocate, the compression mechanism is simultaneously driven to move. The compression mechanism first inhales external air, and then is driven by the movable mechanism to compress the inhaled air. Then, the blowing mechanism uses the compressed gas. When the beating plate 6 just beats the cloth bag 2, the compression mechanism reaches the maximum compression position. At this time, the blowing mechanism is closest to the cloth bag 2. The blowing mechanism blows the compressed gas of the compression mechanism to the cloth bag 2 at this time. The gas with a certain kinetic energy after compression impacts on the cloth bag 2. Since the cloth bag 2 has a gas permeable feature, when the gas passes through the cloth bag 2 and acts on the polyethylene wax powder gathered on the outer surface of the cloth bag 2, the kinetic energy air blows away the gathered polyethylene wax powder. The dispersed polyethylene wax powder falls. The beating plate 6 and the blowing mechanism simultaneously act on the cloth bag 2, which can improve the cleaning effect of the polyethylene wax powder gathered on the outer surface of the cloth bag 2.

[0024] As shown in Figure 7 and Figure 8 , the movable mechanism includes a push rod 7. One end of the push rod 7 is bolted to the top of the beating plate 6 towards the inside of the square frame 5. The other end of the push rod 7 is welded with a ball head 8. The square frame 5 is provided with a rotating shaft 9 perpendicular to the push rod 7. The top of the square frame 5 at both ends of the rotating shaft 9 is bolted with an axle seat 11. The both ends of the rotating shaft 9 are sleeved with the axle seat 11. One end of the rotating shaft 9 is provided with a motor 1 2. The output end of the motor 1 2 is inserted with the rotating shaft 9. The middle of the rotating shaft 9 is sleeved with a push plate 10 and is bolted. The end of the push plate 10 is close to the ball head 8 of the push rod 7 away from the beating plate 6. The sleeve 13 is sleeved on the push rod 7 above the square frame 5. The push rod 7 in the sleeve 13 is sleeved with a spring 16. One end of the spring 16 is close to the end of the sleeve 13 near the beating plate 6. The other end of the spring 16 is fixed with a ring plate 14 on the push rod 7. The other end of the spring 16 is close to the ring plate 14.

[0025] When the mechanism is working, motor 12 starts and rotates, driving the inserted shaft 9 to rotate. When the shaft 9 rotates, it drives the lever 10 to rotate around the shaft 9. Since the lever 10 abuts against the ball head 8 of the push rod 7, the lever 10 will push the push rod 7 towards the striking plate 6 when it rotates. Since the push rod 7 and the striking plate 6 are fixed, when the push rod 7 is pushed by the lever 10, it will drive the striking plate 6 closer to the bag 2. The lever 10 pushes the push rod 7 and the striking plate 6 quickly at a certain speed, so that the striking plate 6 contacts the inner surface of the bag 2 at a certain speed to form an impact. When the impact force acts on the bag 2 and the polyethylene wax powder blocks accumulated on the outer surface of the bag 2, it can loosen or disperse the accumulated polyethylene wax powder blocks. The scattered polyethylene wax powder falls naturally under the action of gravity, thereby achieving the effect of cleaning the polyethylene wax powder accumulated on the outer surface of the bag 2. When the lever 10 pushes the push rod 7, the movement of the push rod 7 will cause the fixed annular plate 14 to move synchronously. When the annular plate 14 moves towards the striking plate 6, it will compress the spring 16. When the contact between the lever 10 and the push rod 7 is broken, the lever 10 can no longer apply a pushing force to the push rod 7. Without the obstruction of the pushing force, the spring 16 will elastically deform and recover. Since one end of the spring 16 is against the sleeve 13 and the other end deforms and recovers in the direction away from the striking plate 6, the deformation recovery will push the annular plate 14 away from the striking plate 6. Since the annular plate 14 is fixed to the push rod 7 and the push rod 7 is fixed to the striking plate 6, the deformation recovery of the spring 16 will eventually drive the striking plate 6 away from the bag 2 to reset until the lever 10 rotates one revolution, contacts the push rod 7 again, and pushes the push rod 7 again, thus forming a reciprocating cycle.

[0026] like Figure 8 As shown, the compression mechanism includes an air inlet pipe 17 welded and fixed to the top of the sleeve 13. A one-way valve is installed at the end of the air inlet pipe 17 by thread. The annular plate 14 slides and seals with the inner wall of the sleeve 13. A fastener 15 is installed on the top of the square frame 5 by bolts. The sleeve 13 is located inside the fastener 15 and is clamped and fixed by the fastener 15.

[0027] As the annular plate 14 moves along with the push rod 7 and compresses the spring 16, the annular plate 14 moves towards the striking plate 6 within the sleeve 13, reducing the space area within the sleeve 13 in the direction of the annular plate 14's movement. With the space area decreasing while the internal gas volume remains constant, the gas pressure increases. Therefore, the movement of the annular plate 14 towards the striking plate 6 compresses the gas within the sleeve 13. Since the one-way valve is designed for one-way air intake, the pressure inside the sleeve 13 is higher than the external pressure. The one-way valve remains closed under this higher internal pressure. When the spring 16 recovers its deformation, it pushes the annular plate 14 further away... When the sleeve moves away from the striking plate 6, the compressed gas inside the sleeve 13 is consumed by the air blowing assembly, and the space inside the sleeve 13 at the spring 16 position increases. At this time, the internal pressure of the sleeve 13 at the spring 16 position is lower than the external pressure. Under the lower internal pressure, the one-way valve is pushed by the higher external pressure to open. External air is replenished into the sleeve 13 at the spring 16 position through the opened one-way valve. When the lever 10 pushes the push rod 7 again, the annular plate 14 moves towards the striking plate 6 again, compressing the gas inside the sleeve 13 at the spring 16 position, thus forming a reciprocating cycle.

[0028] like Figures 7-9 As shown, the blowing mechanism includes an elastic roll 23. Connecting pipes 22 are welded to two adjacent sides of the striking plate 6 facing the bag 2. The roll end of the elastic roll 23 is sleeved with the connecting pipe 22. The push rod 7, the striking plate 6, and the elastic roll 23 are all hollow. The elastic roll 23 is made of thermoplastic elastomer TPE material. The end away from the connecting pipe 22 is sealed. A vent hole 18 is opened on the push rod 7 on the inner side of the sleeve 13 facing the striking plate 6. The sleeve 13, the vent hole 18, the push rod 7, the striking plate 6, the connecting pipe 22, and the elastic roll 23 are connected. An opening is opened on the side of the elastic roll 23 facing the bag 2.

[0029] When the ring plate 14 moves to the direction of the beating plate 6, the gas in the sleeve 13 at the position of the spring 16 is compressed and pushed into the hollow push rod 7 and the beating plate 6 and the elastic roll 23 in communication with the push rod 7 through the air hole 18, the internal pressure of the sleeve 13, the push rod 7, the beating plate 6 and the elastic roll 23 which are in communication as a whole is increased, since the elastic roll 23 made of TPE has elasticity and is hollow, when the internal pressure of the elastic roll 23 is increased, the effect of internal inflation is formed on the elastic roll 23, the elastic roll 23 is inflated and stretched under the action of internal pressure, when the elastic roll 23 is stretched, the beating plate 6 is in contact with the inner side of the cloth bag 2, at this time, the elastic roll 23 can beat the inner side of the cloth bag 2 at the position deviated from the beating plate 6, and the elastic roll 23 has a hole on the side facing the cloth bag 2, when the internal pressure of the elastic roll 23 is increased, the gas in the elastic roll 23 is sprayed outwards through the hole, the sprayed gas directly sprays on the inner side of the cloth bag 2, the cloth bag 2 is breathable, the gas directly blows on the polyethylene wax powder accumulated on the outer surface of the cloth bag 2 after passing through the cloth bag 2, the gas can blow the polyethylene wax powder off the cloth bag 2, the beating of the elastic roll 23 can also blow the polyethylene wax powder off the cloth bag 2, and the beating plate 6 also beats the cloth bag 2, the three can comprehensively improve the cleaning effect of the polyethylene wax powder on the cloth bag 2.

[0030] As shown in Figure 6 The housing 1 below the square frame 5 is provided with a circular ring-shaped seat 24, the square frame 5 is welded and fixed with the seat 24, the bottom of the seat 24 is provided with a supporting bearing 25 through bolt installation in the bottom of the housing 1, the outer side of the seat 24 is integrally formed with a plurality of convex teeth 42 at equal intervals, the housing 1 outside the seat 24 is provided with a gear 26, the gear 26 is engaged with the convex teeth 42, the housing 1 above the gear 26 is provided with a shaft frame 28 through bolt installation, the gear 26 is sleeved with the shaft frame 28, the top of the shaft frame 28 is provided with a motor two 27 through bolt installation, the output end of the motor two 27 is inserted with the gear 26.

[0031] When the beating plate 6 and the elastic roll 23 act on the cloth bag 2 from the inner side of the cloth bag 2, the cloth bag 2 can only be cleaned at a certain position. When the accumulated polyethylene wax powder at different positions on the outer side of the cloth bag 2 needs to be cleaned, the second motor 27 is controlled to drive the gear 26 to rotate, the gear 26 is engaged with the protruding teeth 42, the support bearing 25 supports the support seat 24, and thus the support seat 24 is driven by the gear 26 to rotate around the support bearing 25 as the axis. The beating plate 6 is installed and supported on the square frame 5, and the square frame 5 is welded and fixed with the support seat 24. Therefore, the rotation of the support seat 24 finally drives the beating plate 6 to rotate synchronously. After the beating plate 6 is rotated to the required position on the inner side of the cloth bag 2, the second motor 27 is stopped, and the first motor 12 is started again to drive the beating plate 6 and the elastic roll 23 to act on the inner side of the cloth bag 2 at the current position, so as to clean or emphasize cleaning of the accumulated polyethylene wax powder on the outer side of the cloth bag 2 at the current position, and flexible adjustment of cleaning according to different positions and different situations is realized.

[0035] The contour rod 29 extends into the cloth bag 2 to support and maintain the opening of the cloth bag 2. In this way, when the beating plate 6 beats the cloth bag 2, the cloth bag 2 at the beating position will not be flattened, and the cloth bag 2 will not be deformed and recovered, so that the beating at the position cannot beat the cloth bag 2.
