Description

Technical Field

[0001] The utility model relates to the technical field of carbon black conveying pipeline cleaning, in particular to a carbon black conveying pipeline accumulated material cleaning device. Background Art

[0002] Carbon black powder is a fine powder of amorphous carbon, mainly obtained by high-temperature cracking, combustion or pyrolysis of hydrocarbon compounds (such as petroleum, natural gas, etc.). As a commonly used industrial raw material, carbon black powder has a high specific surface area, good hiding power and tinting power, and is widely used in rubber, ink, coating and other industries.

[0003] For example, in the process of making rubber using carbon black powder, the output material is usually transported through a conveying pipe. However, due to the characteristics of carbon black powder (such as easy agglomeration and strong adhesion), residues may be left in the pipe. In order to ensure the smooth flow of the pipe and the smooth progress of subsequent work, the conveying pipe needs to be regularly cleaned to remove the accumulated material. However, in the cleaning of the accumulated material, since the conveying pipe has a certain height, it is inconvenient to use a cleaning brush at the cleaning window and the efficiency is not high. Therefore, a carbon black conveying pipe accumulated material purging device is proposed. Utility Model Content

[0004] Based on the above description, the utility model provides a carbon black conveying pipeline accumulated material cleaning device, which solves the technical problems of inconvenient operation and low efficiency in using a brush to clean the carbon black conveying pipeline accumulated material.

[0005] The utility model solves the above technical problems with the following technical solutions: a carbon black conveying pipeline material purge device, used for purging the material conveying pipeline, wherein the turning point of the material conveying pipeline is integrally connected with a cleaning window, comprising:

[0006] A docking structure is detachably connected to the cleaning window and includes a docking sleeve adapted to fit inside the cleaning window, a docking flange detachably connected to the cleaning window is fixed to the outside of the docking sleeve, and a center hole is opened at the center of the docking sleeve;

[0007] The purge structure includes a butt-joint pipe welded and installed at the center hole. A screw blower is provided on one side of the butt-joint pipe and located outside the material conveying pipeline. An air duct is provided on the other side and located at the horizontal part of the conveying pipeline. A plurality of purge air holes distributed in a circular array are provided on the outside of the air duct.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, it also includes a plurality of sealing sleeves distributed linearly at equal distances, and a position adjustment mechanism connected to any group of sealing sleeves. A connecting rod is fixed between any two adjacent groups of sealing sleeves, so that the position adjustment mechanism can synchronously adjust the positions of all sealing sleeves.

[0010] Furthermore, the position adjustment mechanism includes a telescopic component, which is fixed to the outside of the docking sleeve by bolts. A connecting rod is provided at the telescopic end of the telescopic component, and a ring sleeve is fixed at the end of the connecting rod away from the telescopic component. A connecting rod 2 is fixed between the ring sleeve and the adjacent sealing sleeve.

[0011] Furthermore, the length of the sealing sleeve is greater than the diameter of the purge air hole, so that the sealing sleeve can close the purge air hole.

[0012] Furthermore, the telescopic component is a cylinder or an electric push rod.

[0013] Furthermore, a brush is provided on the outside of the sealing sleeve. When the telescopic component cyclically retracts and contracts, the brush is allowed to cyclically move back and forth to clean the attachments on the inner wall of the horizontal portion of the conveying pipe.

[0014] Furthermore, the diameter of the docking sleeve is equal to the inner diameter of the cleaning window, so that when the docking sleeve is placed in the cleaning window, the cleaning window can provide a support point for the docking sleeve.

[0015] Furthermore, the docking flange is located outside the cleaning window and fits the cleaning window, and the docking flange and the cleaning window are fixed by bolts.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. This carbon black conveying pipeline material purge device, when detachably mounted on a cleaning window using a docking structure, utilizes the characteristics of a screw blower that can provide a stable and continuous airflow, allowing the air used for purge to flow out from the purge air holes on the air duct and blow the horizontal part of the material conveying pipeline to remove the accumulated material adhering to the inner wall of the material conveying pipeline. After installation, this operation does not require continuous holding, reducing the burden on the operator, and can conveniently and quickly complete the cleaning of the accumulated material.

[0018] 2. After the purge is completed, the carbon black conveying pipeline accumulation purge device can use the telescopic component to adjust the position of the sealing sleeve so that the sealing sleeve can subsequently cover the purge air hole to avoid clogging of the purge air hole.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] In order to avoid dust and ensure the cleanliness of the workshop, conveying pipes are gradually being used to transport carbon black powder. However, when using conveying pipes, material accumulation may occur in the conveying pipes due to the characteristics of carbon black powder that is easy to agglomerate and has strong adhesion, or insufficient conveying air flow pressure or pipe size. The accumulated material will exist in the horizontal part of the conveying pipe. This application mainly provides a carbon black conveying pipe material accumulation purging device, which is mainly used to purge the conveying pipe, that is, the material conveying pipe 1 in this application, specifically to deal with the accumulated material in the horizontal part of the material conveying pipe 1, aiming to provide a cleaning device that is efficient and can reduce the operating burden and is used to deal with the accumulated material in the material conveying pipe 1. It should be noted that the turning part of this material conveying pipe 1 is integrated with a cleaning window 2.

[0027] like Figure 1 and Figure 2 As shown, a carbon black conveying pipeline material accumulation purging device in this embodiment includes a docking structure 3 and a purging structure 4, wherein the docking structure 3 is used to allow the carbon black conveying pipeline purging device to be fixed at the cleaning window 2 of the material conveying pipeline 1, and the purging structure 4 is mainly used to purge the accumulated material on the inner wall of the horizontal portion of the material conveying pipeline 1, so that the accumulated material after the purge can be subsequently cleared out when the power source used for pneumatic transportation of the existing material conveying pipeline 1 is started. The power source used for pneumatic transportation of the material conveying pipeline 1 is a prior art and is not a technical feature structure of the present application. It is not shown in the figure and will not be described in detail here:

[0028] In order to facilitate understanding of the above-mentioned docking structure 3 and purge structure 4, they are described in sequence. First, Figure 1-4 As shown, the docking structure 3 in this embodiment is detachably connected to the cleaning window 2 and includes a docking sleeve 31 adapted to the inner side of the cleaning window 2. The diameter of this docking sleeve 31 is equal to the inner diameter of the cleaning window 2. In this way, when the docking sleeve 31 is placed in the cleaning window 2, the cleaning window 2 can provide a support point for the docking sleeve 31. When this carbon black conveying pipeline material accumulation device is fixed, the operator's hands are freed, and the operator does not need to continue holding the operation, thereby reducing the operator's operating burden. A docking flange 32 detachably connected to the cleaning window 2 is fixed on the outside of the docking sleeve 31. This docking flange 32 is located on the outside of the cleaning window 2 and fits with the cleaning window 2. The size is preferably the same as the flange diameter of the cleaning window 2. In this way, the docking flange 32 and the cleaning window 2 can be fixed by bolts to achieve its detachable connection with the cleaning window 2.

[0029] It should be noted that a central hole is opened at the center of the docking sleeve 31 , and the central hole is used to provide space for the docking tube 41 in the subsequent purge structure 4 .

[0030] As for the purge structure 4, please refer to Figure 2 ,like Figure 2 As shown, this purge structure 4 includes a butt joint 41, a screw blower 42 and an air duct 43, wherein the butt joint 41 is welded and installed at the center hole, and the butt joint 41 has two ends, one end is located in the cleaning window 2, and the other end is located outside the cleaning window 2, and the screw blower 42 is located outside the material conveying pipeline 1, and is connected to one side of the butt joint 41, and the two can be fixed with bolts, and the air duct 43 is located in the horizontal part of the material conveying pipeline 1, and is connected to the other side of the butt joint 41, and these two are also fixed with bolts. It should be noted that a number of purge air holes distributed in a circular array are opened on the outside of the air duct 43, so that the wind used for purge can be distributed to various places on the inner wall of the horizontal part of the material conveying pipeline 1.

[0031] When designed in this way, the carbon black conveying pipeline material accumulation purging device has a purging function, and this function operates as follows: after the carbon black conveying pipeline material accumulation purging device is fixed by the docking structure 3, the screw blower 42 is used to provide a stable and continuous airflow. The screw blower 42 is started, and the air used for purging is allowed to flow out from the purging air holes on the air duct 43 through the conduction of the docking pipe 41 and blow the horizontal part of the material conveying pipeline 1 to remove the accumulated material adhering to the inner wall of the material conveying pipeline 1. After installation, this operation does not require continuous holding, which reduces the burden on the operator and can complete the cleaning of the accumulated material conveniently and quickly.

[0032] Considering that there is dust inside the material conveying pipeline 1 after it is purged, the carbon black conveying pipeline accumulation purging device needs to be left still for a period of time during operation to protect the purging air holes. Figure 2 and 3 As shown, in a certain embodiment, the carbon black conveying pipeline accumulation purging device also includes a plurality of sealing sleeves 44 linearly distributed at equal distances, and a position adjustment mechanism 5 connected to any group of sealing sleeves 44, and a connecting rod 45 is fixed between any two adjacent groups of sealing sleeves 44, so that the position adjustment mechanism 5 can synchronously adjust the positions of all sealing sleeves 44.

[0033] The preferred solution for the position adjustment mechanism 5 is as follows: the position adjustment mechanism 5 includes a telescopic component 51, which is fixed to the outside of the docking sleeve 31 by bolts. In this way, the power source for the telescopic action can avoid contact with the accumulated material and dust in the material conveying pipeline 1, and a connecting rod 52 is provided at the telescopic end of the telescopic component 51, which passes through the other side of the docking sleeve 31 and is located inside the material conveying pipeline 1 after the carbon black conveying pipeline accumulation purge device is installed. A ring sleeve 53 is fixed to the end of the connecting rod 52 away from the telescopic component 51, and the ring sleeve 53 is slidably connected to the outside of the air duct 43. A connecting rod 2 54 is fixed between the ring sleeve 53 and the adjacent sealing sleeve 44 to achieve connection between the ring sleeve 53 and the sealing sleeve 44. In this way, under the telescopic action of the telescopic component 51, the sealing sleeve 44 is allowed to move synchronously with the ring sleeve 53 to achieve position adjustment of the sealing sleeve 44.

[0034] Regarding the description of the telescopic component 51, the telescopic component 51 is a cylinder or an electric push rod, and is used to provide telescopic characteristics.

[0035] It should be noted that, in order to ensure that the sealing sleeve 44 can complete the sealing and blocking of the purge air hole, the length of the sealing sleeve 44 is preferably greater than the diameter of the purge air hole, so that the sealing sleeve 44 can seal the purge air hole.

[0036] At this time, during operation, after the material conveying pipeline 1 is purged, the telescopic characteristics of the telescopic component 51 are utilized to allow the ring sleeve 53 to be displaced, and the sealing sleeve 44 is displaced synchronously with the ring sleeve 53. In this way, the sealing sleeve 44 can shield and protect the purging air hole after the purging is completed.

[0037] To enhance the cleaning capability, mechanical cleaning is performed. In one embodiment, Figure 4 As shown, a brush 6 is fixed to the outside of the sealing sleeve 44. When the blowing capacity is insufficient, in order to complete the cleaning, the telescopic characteristics of the telescopic component 51 are utilized. When the telescopic component 51 is cyclically extended and retracted, the brush 6 is allowed to move back and forth to clean the attachments on the inner wall of the horizontal part of the material conveying pipeline 1.

[0038] It should be noted that the use of the telescopic component 51 to drive the brush 6 for cleaning and the use of the blowing structure 4 need to be performed separately.

[0039] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
