Description

Technical Field

[0001] This utility model relates to the technical field of pigment packaging material conveying equipment, specifically a constant pressure screw conveyor for organic pigments. Background Technology

[0002] Organic pigments are a class of pigments made from organic compounds. They are insoluble in water and the medium in which they are used, and they typically color objects in a highly dispersed particulate state. Organic pigments are usually packaged in both large and small packages, and screw conveyors are designed to facilitate switching between these packaging systems. A constant-pressure screw conveyor system is required for packaging organic pigments.

[0003] In actual material conveying processes, the sealing devices at both ends of the conveying screw experience varying degrees of wear and loosening with increasing usage time. Because positive pressure can be generated in the casing during conveying, material can easily leak or spray out from the sealing devices. Frequent replacement of the sealing packing and tightening are necessary. Therefore, this does not meet existing requirements. To address this, we propose a constant-pressure screw conveyor device for organic pigments. Utility Model Content

[0004] The purpose of this invention is to provide a constant-pressure screw conveyor for organic pigments, addressing the problems mentioned in the background section regarding the sealing devices at both ends of the conveying screw. These devices experience wear and loosening over time, and the positive pressure generated in the casing during conveying easily causes material to leak or spray out from the sealing devices. Frequent replacement of the sealing packing and tightening are required, thus failing to meet existing requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant pressure screw conveyor for organic pigments, comprising: a housing; Also includes: The mounting base is located on the front and rear sides of the housing; A fixing tube is provided at the end of the fixing base; The feed tube is located at the end of the fixed tube. The feed tube and the fixed tube cooperate to transport organic pigments. A connecting component is disposed between the fixed tube and the material tube. The connecting component is used to seal the connection between the fixed tube and the material tube, and at the same time, it prevents dusty organic pigments from getting stuck at the connection. The connecting component includes a sealing tube, and airbags are fixedly connected to both ends of the sealing tube.

[0006] The housing is internally connected to a spiral conveyor shaft, and a motor is installed at the top of the spiral conveyor shaft.

[0007] The sealing tube is fixedly connected to multiple mounting screws at both ends. The mounting screws are arranged in a ring array about the central axis of the sealing tube. Both the fixed tube and the material tube are detachably connected to the mounting screws via connecting nuts.

[0008] Both the fixed tube and the material tube have sealing grooves at their ends, and the external dimensions of the sealing tube match the internal dimensions of the sealing groove.

[0009] The airbag is L-shaped and is semi-enclosed to the material tube.

[0010] The outer wall of the sealing tube has multiple air inlets at equal intervals, and the two airbags are connected through the air inlets. An air valve is installed at one end of the sealing tube.

[0011] The innermost part of the airbag has a one-way valve installed on its bottom inner wall, and an exhaust pipe is installed at the rear end of the one-way valve. The exhaust pipe is connected to the fixed pipe.

[0012] This utility model has at least the following beneficial effects: When organic pigments are fed into the housing through the feed pipe, positive pressure may be generated inside the housing. The air pressure compresses the air bladder, forcing the bottom to tilt up and expose the one-way valve at the bottom. The air brought in by the feed will be discharged outward through the one-way valve. Thus, the air pressure inside the housing is balanced, ensuring stable pressure during the organic pigment conveying process, thereby maintaining the uniformity of material flow and preventing material from seeping or spraying out at the sealing device.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: a constant pressure screw conveyor for organic pigments, comprising: a housing 001; Also includes: Fixing base 002 is disposed on the front and rear sides of housing 001; Fixed tube 003 is provided at the end of fixed base 002; Material pipe 004 is located at the end of fixed pipe 003. Material pipe 004 and fixed pipe 003 cooperate with each other to transport organic pigments. The connecting component 005 is disposed between the fixed tube 003 and the material tube 004. The connecting component 005 is used to seal the connection between the fixed tube 003 and the material tube 004, and at the same time, it prevents the powdery organic pigment from getting stuck at the connection. The connecting component 005 includes a sealing tube 501, and airbags 502 are fixedly connected to both the front and rear ends of the sealing tube 501.

[0017] The housing 001 is rotatably connected to a screw conveyor shaft 110, and a motor 120 is installed at the top of the screw conveyor shaft 110.

[0018] The operator can connect the fixed pipe 003 and the material pipe 004 through the sealing pipe 501 to facilitate the connection between the housing 001 and the device for inputting organic pigments, ensuring uninterrupted delivery of organic pigments. When the organic pigments are fed into the housing 001 through the material pipe 004, positive pressure may be generated inside the housing 001, thereby compressing the air bladder 502. Since the air bladder 502 is L-shaped, when it is under pressure, the bottom of the air bladder 502 tilts up, thus exposing the one-way valve 550 at the bottom. As the air brought in by the feed is discharged outward through the one-way valve 550, the air pressure inside the housing 001 is balanced, ensuring stable pressure during the delivery of organic pigments and maintaining the uniformity of material flow.

[0019] Multiple mounting screws 510 are fixedly connected to both ends of the sealing tube 501. The multiple mounting screws 510 are arranged in a ring array about the central axis of the sealing tube 501. The fixed tube 003 and the material tube 004 are detachably connected to the mounting screws 510 through the connecting nut 520.

[0020] Both the fixed tube 003 and the material tube 004 have sealing grooves 310 at their ends, and the external dimensions of the sealing tube 501 match the internal dimensions of the sealing groove 310.

[0021] The fixed pipe 003 and the material pipe 004 are respectively connected to the sealing pipe 501 by the mounting screw 510. The top of the mounting screw 510 is fastened by the connecting screw to form a material conveying channel. At the same time, the sealing groove 310 makes the connection between the sealing pipe 501 and the fixed pipe 003 and the material pipe 004 maze-like to prevent the organic pigment inside the shell 001 from leaking.

[0022] The airbag 502 is L-shaped and is semi-enclosed to the material tube 004.

[0023] The outer wall of the sealing tube 501 is provided with multiple air inlets 530 at equal intervals. The two airbags 502 are connected through the air inlets 530. An air valve 540 is installed at one end of the sealing tube 501.

[0024] In this system, the operator can supply air to one of the air bladders 502 through the air valve 540. Under the action of the air supply hole 530, the gas between the two air bladders 502 is interconnected until both air bladders 502 are fully inflated, surrounding the connection between the fixed pipe 003, the material pipe 004, and the sealing pipe 501. Thus, under the compression of the air bladders 502, the connection is further sealed. The two air bladders 502 simultaneously protect the inner and outer sides of the pipeline. Since the two air bladders 502 are interconnected, the operator can determine whether the air bladders 502 inside the pipeline are in normal working condition by observing the air bladders 502 leaking to the outside. This facilitates immediate repair and adjustment of the device in case of an accident. At the same time, since the air bladders 502 are inside the pipeline and shield the connection, they can effectively prevent the material from seeping or spraying out at the connection due to positive pressure. Example 2

[0025] like Figure 5 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a one-way valve 550 is installed on the inner wall of the bottom end of the airbag 502 located on the inner side. An exhaust pipe 560 is installed at the rear end of the one-way valve 550, and the exhaust pipe 560 is connected to the fixed pipe 003.

[0026] Since the one-way valve 550 is located on the inner wall of the bottom end of the airbag 502, it effectively prevents organic dust from entering the one-way valve 550 during the conveying process.
