DETAILED DESCRIPTION

[0035] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0036] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] Secondly, as used herein, "one embodiment" or "an embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive of other embodiments.

[0038] Embodiment 1

[0039] Referring to Figure 1 and Figure 4 , this is the first embodiment of the present invention. This embodiment provides an efficient dust removal device for the production of PU air pipes. The efficient dust removal device for the production of PU air pipes includes a processing component 100 and a dust removal component 200. Through the setting of the dust removal component 200, while stirring the PU masterbatch, gas can be introduced to uniformly contact the masterbatch, forming a lateral pushing force, which cooperates with the circumferential stirring direction to improve the uniformity of masterbatch distribution. Moreover, the gas inlet aperture will also change dynamically, greatly improving the overall uniformity of dust removal treatment.

[0040] Specifically, the processing component 100 includes a processing cylinder 101. A hollow pipe 101a is movably connected to the processing cylinder 101. A feeding hopper 101b is fixed to the top of the processing cylinder 101. A first air hole 101c is opened at the inner top of the processing cylinder 101. A screening mesh plate 101d is embedded at the inner bottom of the processing cylinder 101. A driving member 102 is arranged on one side of the processing cylinder 101. A water storage tank 103 is fixed to the bottom of the processing cylinder 101. An air extraction pump 104 is arranged on the other side of the processing cylinder 101.

[0041] The hollow pipe 101a is movably connected to the processing cylinder 101 through a sealed bearing.

[0042] A sealed baffle is rotatably connected to the top of the feeding hopper 101b, which is used to completely cover and block the top of the feeding hopper 101b after feeding.

[0043] The water storage tank 103 contains an appropriate amount of clear water. A sewage valve is fixed to the rear side inside the water storage tank 103, as shown in the accompanying drawings of the specification Figure 10 as shown.

[0044] The bottom of the air pump 104 and the bottom of the water storage tank 103 are in the same plane, which is conducive to the stable placement of the entire device.

[0045] Specifically, the dust removal assembly 200 is arranged on the treatment barrel 101, including a toggle member 201 located in the treatment barrel 101, including a stirring frame 201a arranged in the inner cavity of the treatment barrel 101, a spiral rod 201a-1 is fixed on the stirring frame 201a, a displacement sleeve 201b is arranged on the inner side of the stirring frame 201a, a toggle rod 201b-1 is fixed to the bottom of the displacement sleeve 201b, an auxiliary member 201c is arranged on one side of the displacement sleeve 201b, and an air induction member 202 is arranged on the top of the treatment barrel 101. , including an air hood 202a slidably connected to the outside of the treatment tube 101, a second air hole 202a-1 is opened in the inner circle of the air hood 202a, an air injection head 202c is connected to the hollow tube 101a, a transmission part 202d is arranged on the hollow tube 101a, a dust suppression part 203 is arranged in the water tank 103, including a carrier 203a movably connected to the water tank 103, a drainage plate 203b is fixed on the top of the water tank 103, and an interception net 203c is embedded in one side of the water tank 103.

[0046] The air inlet end of the vacuum pump 104 is connected to an air inlet pipe, and the other end of the air inlet end is fixed on the water storage tank 103 and is located outside the interception net 203c, so that when the vacuum pump 104 is working, the gas in the water storage tank 103 is pumped out.

[0047] By setting the shifting member 201, when the gas is introduced into the hollow tube 101a, the shifting rod 201b-1 can be laterally displaced, and the mother particles in the processing tube 101 can be well stirred in cooperation with the circularly rotating stirring frame 201a.

[0048] By setting the air guide member 202, the air inlet aperture can be dynamically changed during the stirring process, so that the air flow entering the processing cylinder 101 is more evenly distributed, which is conducive to uniform contact with the PU masterbatch.

[0049] The dust suppression member 203 is provided to carry the fallen dust and impurities, and the water in the water storage tank 103 is used to settle the dust and impurities, thereby avoiding the generation of secondary dust.

[0050] Example 2

[0051] Reference Figures 2 to 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0052] Specifically, the driving member 102 includes a motor 102a disposed on one side of the processing cylinder 101, a second gear disc 102c is fixed to the output end of the motor 102a, a first gear disc 102b is fixed to the outer ring of the hollow tube 101a, and a third gear disc 102d is fixed to the carrier 203a.

[0053] Both the first toothed disc 102b and the second toothed disc 102c, and the second toothed disc 102c and the third toothed disc 102d are in a meshed state.

[0054] The specifications of the first toothed disc 102b, the second toothed disc 102c, and the third toothed disc 102d decrease in sequence. That is, when the second toothed disc 102c is actively rotated by the motor 102a, the first toothed disc 102b will rotate at a reduced speed to cope with a larger load, and the third toothed disc 102d will rotate at an increased speed to cope with high-frequency settlement.

[0055] A fixed seat 101e is fixed at the center on one side of the processing cylinder 101, and a discharge valve 101f is fixed at the inner bottom of the processing cylinder 101.

[0056] When the discharge valve 101f is in an open state, the PU masterbatch in the processing cylinder 101 can be discharged.

[0057] A guide rod 201b-2 is slidably connected inside the displacement sleeve 201b, and a positioning block 201b-3 is installed at the top of the shift lever 201b-1.

[0058] One end of the guide rod 201b-2 is fixed on the fixed seat 101e, and an auxiliary seat is fixed at the other end of the guide rod 201b-2. The auxiliary seat is movably connected to the rotating rod 201c-3 through a bearing. This design can effectively improve the installation stability of the guide rod 201b-2 and the rotation stability of the rotating rod 201c-3.

[0059] A housing 201d is fixed at one end of the hollow tube 101a, and a through hole 201d-1 is opened at one end of the housing 201d.

[0060] The housing 201d is communicated with the hollow tube 101a and is used to guide the input air flow and uniformly diffuse it into the processing cylinder 101 in cooperation with a plurality of through holes 201d-1.

[0061] The auxiliary member 201c includes a movable rod 201c-1 movably connected to the housing 201d. A turbine 201c-2 is fixed on the movable rod 201c-1. One end of the movable rod 201c-1 is fixed with a rotating rod 201c-3, and a spiral groove 201c-4 is opened on the rotating rod 201c-3.

[0062] The spiral groove 201c-4 cooperates with the positioning block 201b-3 so that when the rotating rod 201c-3 rotates, the shift lever 201b-1 and the displacement sleeve 201b can generate a lateral displacement. Similarly, when the shift lever 201b-1 is driven by an external force to generate a lateral displacement, the rotating rod 201c-3 will also rotate.

[0063] The turbine 201c-2 is located within 201s. When it is subjected to the air flow introduced through the hollow tube 101a, the auxiliary part 201c rotates naturally, and the rotation direction is opposite to that of the hollow tube 101a.

[0064] The inner top of the air extraction hood 202a and one end of the air injection head 202c are both connected to the air inlet pipe 202b. The second air hole 202a-1 cooperates with the first air hole 101c. Connecting frames 202a-2 are fixed on both sides of the air extraction hood 202a.

[0065] When the second air hole 202a-1 and the first air hole 101c completely overlap, the air flow transmission area reaches the maximum. When the gas volume remains unchanged, the gas will diffuse into the treatment cylinder 101. Similarly, when the second air hole 202a-1 and the first air hole 101c are staggered, as the air flow transmission area gradually decreases, when the gas volume remains unchanged, the gas will be more concentrated and injected into the treatment cylinder 101.

[0066] One connecting frame 202a-2 is movably connected to the fixed seat 101e, and the other connecting frame 202a-2 is movably connected to the hollow tube 101a.

[0067] The transmission part 202d includes a first gear ring 202d-1 movably connected to the hollow tube 101a. A sector gear ring 202d-2 is fixed on one side of the connecting frame 202a-2, and a torsion spring 202d-3 is installed on the other side of the connecting frame 202a-2.

[0068] A positioning rod 202d-4 is provided at the bottom of the first gear ring 202d-1. A sector gear 202d-5 and a second gear ring 202d-6 are respectively fixed on the positioning rod 202d-4. The sector gear 202d-5 meshes with the sector gear ring 202d-2.

[0069] The second gear ring 202d-6 meshes with the first gear ring 202d-1.

[0070] When the first gear ring 202d-1 rotates, it can drive the second gear ring 202d-6 to rotate. Then, under the connection of 201d-4, the sector gear 202d-5 will also rotate. When the sector gear 202d-5 meshes with the sector gear ring 202d-2, as the sector gear 202d-5 rotates, the sector gear ring 202d-2 will drive the connecting frame 202a-2 to rotate synchronously, and the torsion spring 202d-3 will tighten, and the angle of the air extraction hood 202a will change. When the sector gear 202d-5 and the sector gear ring 202d-2 are no longer meshed, under the torsion of the torsion spring 202d-3, the connecting frame 202a-2 and the air extraction hood 202a will rotate back to their original positions.

[0071] In use, an appropriate amount of PU masterbatch is added into the treatment cylinder 101 through the feed hopper 101b, and the motor 102a is controlled to work. At the same time, clean external gas is introduced through the air guiding member 202 to uniformly remove dust from the masterbatch in the treatment cylinder 101. Dust and impurities fall into the water storage tank 103 through the screening mesh plate 101d and are sedimented by water, while the gas is pumped out by the working air extraction pump 104 after passing through the intercepting net 203c.

[0072] When the driving member 102 works, under the meshing transmission of the first gear disk 102b and the second gear disk 102c, the hollow tube 101a will rotate synchronously to drive the stirring frame 201a and the screw rod 201a-1 to rotate circumferentially.

[0073] The gas is divided and enters the hollow tube 101a and the air guiding cover 202a. The gas entering the hollow tube 101a is transmitted by the housing 201d and enters the treatment cylinder 101 through the through hole 201d-1. The gas entering the air guiding cover 202a enters the treatment cylinder 101 through the space where the second air hole 202a-1 coincides with the first air hole 101c.

[0074] As the gas in the housing 201d flows, the turbine 201c-2 will rotate, driving the rotating rod 201c-3 to rotate. Under the cooperation of the spiral groove 201c-4 and the positioning block 201b-3, the displacement sleeve 201b will slide on the guiding rod 201b-2 and be shifted to the left by the shift lever 201b-1, cooperating with the circumferentially rotating stirring frame 201a to effectively improve the uniformity of the masterbatch distribution.

[0075] Since the screw rod 201a-1 rotates together with the stirring frame 201a, when the screw rod 201a-1 contacts the shift lever 201b-1, it will actively squeeze the shift lever 201b-1 to move to the right. At this time, the rotating rod 201c-3 and the turbine 201c-2 rotate in the reverse direction. Due to the continuous inflow of air and the continuous circumferential rotation of the screw rod 201a-1, the shift lever 201b-1 can be displaced horizontally within a certain left and right range, ensuring the uniformity of the stirring of the masterbatch.

[0076] When the hollow tube 101a rotates, it synchronously drives the first gear ring 202d-1 to rotate. Under the meshing transmission of the second gear ring 202d-6, the positioning rod 202d-4 and the sector gear 202d-5 will also rotate. Furthermore, under the cooperation of the sector gear ring 202d-2, the connecting frame 202a-2 can be rotated. When the connecting frame 202a-2 rotates by a certain angle, the torsion spring 202d-3 tightens, causing the air guiding cover 202a to rotate around the treatment cylinder 101 by a certain angle. The overlapping area of the second air hole 202a-1 and the first air hole 101c gradually decreases, and the diffusion area of the airflow entering the treatment cylinder 101 decreases while the injection distance increases.

[0077] As the sector gear 202d-5 continues to rotate circumferentially and no longer meshes with the sector gear ring 202d-2, at this time, under the torsional force of the torsion spring 202d-3, the connecting frame 202a-2 and the air guide cover 202a rotate back, and the overlapping area of the second air hole 202a-1 and the first air hole 101c gradually increases. The diffusion area of the air flow entering the treatment cylinder 101 increases, and the injection distance decreases.

[0078] For the dust and impurities in the gas mixture masterbatch, under the screening action of the screening mesh plate 101d, the smaller dust and impurities as well as the smaller unqualified PU masterbatch fall into the water storage tank 103. Under the guiding action of the diversion plate 203b, the impurities gather above the carrier 203a, and the gas is filtered by the intercepting net 203c and then discharged by the air extraction pump 104.

[0079] When the second gear disc 102c and the third gear disc 102d are engaged, the operation of the motor 102a will also cause the carrier 203a to rotate, and then the impurities temporarily stored on its top will fall into the water in the water storage tank 103 to achieve the purpose of sedimentation.

[0080] Embodiment 3

[0081] Referring to Figures 3 to 10 , this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0082] Specifically, the stirring frame 201a includes two brackets and a single cross bar. One of the brackets is fixed to the outer circle of the hollow tube 101a, and the other bracket is movably connected to the fixed seat 101e. The cross bar is fixed between the two brackets, and a bar is fixed to the outer circle of the cross bar, which is used to increase the contact area with the PU masterbatch and improve the stirring uniformity when the stirring frame 201a is rotating, as shown in the accompanying drawings of the specification Figure 5 as shown.

[0083] There is a space between the bottom of the lever 201b-1 and the inner wall of the treatment cylinder 101 to meet the space requirement for the circumferential rotation of the stirring frame 201a.

[0084] A sealing strip is fixed to the outer side of the inner circle of the air guide cover 202a for sealing contact with the outer circle of the treatment cylinder 101 to prevent the gas from flowing out randomly.

[0085] The air inlet pipe 202b is connected to an external air supply pump through a three-way pipe and cooperates with the air extraction pump 104 to form an inflation and deflation operation, which is beneficial to the flow and discharge of dust and impurities.

[0086] A protective shell is installed on the outer sides of the first toothed disc 102b, the second toothed disc 102c and the third toothed disc 102d. The protective shell is fixed on the processing cylinder 101 to ensure the operational stability of the first toothed disc 102b, the second toothed disc 102c and the third toothed disc 102d. One end of the torsion spring 202d-3 is fixed on the connecting frame 202a-2, and the other end of the torsion spring 202d-3 is fixed on the protective shell. Through the setting of the torsion spring 202d-3, torque can be provided for the connecting frame 202a-2, so as to prevent the connecting frame 202a-2 from rotating randomly without external force.

[0087] During actual application, the inner bottom of the processing cylinder 101 is inclined, and the position where the discharge valve 101f is located is at the low end of the inclined plane. This design can guide the PU masterbatch to be discharged well through the discharge valve 101f during the discharging operation.

[0088] During actual application, the screening mesh plate 101d is installed in the processing cylinder 101 by bolts and is sealed at the connection with the processing cylinder 101. This design makes the screening mesh plate 101d in a detachable state. According to the actual processing requirements of the PU masterbatch, a screening mesh plate 101d with an appropriate mesh number can be installed to meet the requirement of intercepting granular masterbatch while allowing dust and impurities to pass through.
