Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal device technology, specifically to an automatic cleaning device for dust removal pipelines. Background Technology
[0002] The dust collectors used in rubber mixing workshops are usually bag filters (fabricated bag dust collectors). A bag filter is a high-efficiency dry filtration dust removal device. Its core working principle is a combination of physical filtration and dynamic cleaning of dust-laden gas through fiber filter bags.
[0003] The main purpose of the dust collector is to remove dust from the feed and discharge ports of the internal mixer. The gas generated during production contains impurities such as carbon black and chemicals. After a period of operation, these impurities tend to accumulate in the dust collection pipelines of the rubber mixing workshop, leading to dust buildup. In severe cases, this can cause pipeline blockage. The accumulated carbon black is prone to spontaneous combustion in high summer temperatures. Additionally, sparks and overheating during rubber discharge can also ignite the carbon black, posing a significant fire hazard. Currently, the workshop cleans the dust collection pipelines by disassembling them. This process is time-consuming and labor-intensive. Carbon black leakage during cleaning seriously affects the on-site environment and the health of workers. Furthermore, excessive disassembly of the dust collection pipelines can cause deformation of the flange connections and dust collection ducts, reducing the lifespan of the pipelines and severely impacting the dust collection efficiency of the machines. Utility Model Content
[0004] To address the shortcomings of existing technologies, an automatic dust removal pipeline cleaning device is proposed. This device solves the problems of disassembling dust removal pipelines for cleaning, which is time-consuming and labor-intensive, causes carbon black leakage during cleaning, and leads to deformation of flange connections and dust removal ducts due to excessive disassembly of the dust removal pipelines.
[0005] To achieve the above objectives, the present invention proposes the following technologies: An automatic cleaning device for dust removal pipelines includes a bypass pipe disposed on one side of the dust removal pipeline and connected to the dust removal pipeline via a connecting pipe. A connector assembly is installed on the dust removal pipeline, and the connecting pipe is connected to the dust removal pipeline via the connector assembly, so as to clean the deposited impurities by blowing air into the dust removal pipeline through the connecting pipe.
[0006] Furthermore, the connector assembly includes a filter nozzle, which includes an air outlet pipe inserted inside the dust removal duct, the air outlet pipe discharging gas to clean impurities on the wall of the dust removal duct.
[0007] Furthermore, the dust removal pipe is provided with an internal thread on its side wall, and the filter nozzle also includes a fixed pipe located at the air inlet end of the air outlet pipe. The outer surface of the fixed pipe is provided with an external thread and is threadedly connected to the internal thread.
[0008] Furthermore, the connector assembly also includes a one-way valve, which is threaded to the outer end of the fixed pipe to enable communication between the one-way valve and the filter nozzle.
[0009] Furthermore, quick connectors are provided at both ends of the connecting pipe, and the connecting pipe is connected to a one-way valve and a bypass pipe respectively through the quick connectors at both ends.
[0010] Furthermore, the internal thread head is specifically a nut located on the surface of the dust removal pipe, and a through hole for installing the filter nozzle is opened on the side wall of the corresponding dust removal pipe. The nut is welded to the dust removal pipe to ensure sealing.
[0011] Furthermore, several connecting pipes are evenly arranged along the length of the dust removal pipeline, and the other end of each connecting pipe is connected to a bypass pipe. One end of the bypass pipe is closed, and the other end is connected to an air source.
[0012] Furthermore, a control component for controlling the on / off state of the gas path is provided between the bypass pipe and the gas source. The control component includes a manual valve and a pressure regulating valve installed between the gas source and the manual valve.
[0013] Furthermore, the control component also includes a pneumatic control valve, which is signal-connected to the auxiliary system and can then switch on and off according to instructions from the auxiliary system to intermittently supply air to the bypass pipe.
[0014] Compared with the prior art, the comprehensive effects brought about by this utility model include: This application uses a bypass pipe and a connecting pipe connected to the dust removal pipe. Gas is introduced into the bypass pipe and then enters the dust removal pipe through the connecting pipe and the joint assembly on the dust removal pipe. This cleans the carbon black and other impurities deposited on the wall of the dust removal pipe, thus avoiding the need to disassemble the dust removal pipe. The cleaning is convenient, efficient, and reduces damage to the dust removal pipe. The joint assembly ensures a tight connection between the connecting pipe and the dust removal pipe, improving the blowing effect of the airflow in the dust removal pipe, thereby effectively cleaning the impurities on the wall.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] Existing technologies typically require regular cleaning of the dust collection pipelines for the master refinery and final refinery within the workshop, resulting in frequent cleaning. Existing disassembly-based cleaning methods have the following problems: 1. Cleaning requires disassembling and cleaning the pipelines, which is time-consuming, labor-intensive, and has a long cleaning cycle, requiring a large investment of manpower.
[0020] 2. During the cleaning of dust removal pipelines, carbon black leakage seriously affects the on-site environment and poses occupational health hazards to personnel.
[0021] 3. Excessive disassembly of the dust removal pipeline leads to deformation of the flange connection and dust removal duct, resulting in fatigue and reduced lifespan, which seriously affects the dust removal effect of the machine.
[0022] 4. The carbon black removed cannot be recycled due to equipment requirements, which increases the difficulty of hazardous waste treatment and indirectly increases the company's treatment costs.
[0023] like Figures 1 to 2 As shown, this application proposes an automatic cleaning device for dust removal pipelines, including a bypass pipe 1. The bypass pipe 1 is disposed on one side of the dust removal pipeline 2 and is connected to the dust removal pipeline 2 through a connecting pipe 3. A connector assembly is installed on the dust removal pipeline 2, and the connecting pipe 3 is connected to the dust removal pipeline 2 through the connector assembly, so as to blow air into the dust removal pipeline 2 through the connecting pipe 3 to clean the deposited impurities.
[0024] By setting up a bypass pipe 1 and a connecting pipe 3 connected to the dust removal pipe 2, gas is introduced into the bypass pipe 1 and enters the dust removal pipe 2 through the connecting pipe 3 and the joint assembly on the dust removal pipe 2. This cleans the carbon black and other impurities deposited on the wall of the dust removal pipe 2, thus avoiding disassembly of the dust removal pipe 2. The cleaning is convenient, efficient, and reduces damage to the dust removal pipe 2. The joint assembly ensures a tight connection between the connecting pipe 3 and the dust removal pipe 2, improving the blowing effect of the airflow in the dust removal pipe 2, thereby effectively cleaning the impurities on the wall.
[0025] Specifically, by adopting the above-mentioned bypass pipe 1 air blowing cleaning structure, there is no need for personnel to climb, disassemble, clean, and assemble, which improves cleaning efficiency and reduces the possibility of accidents to workers. At the same time, there is no need to disassemble the dust removal pipe 2, thereby effectively avoiding carbon black leakage and preventing fatigue of the connecting flange that reduces its service life.
[0026] In the automatic cleaning device for dust removal pipes in this embodiment, the connector assembly includes a filter nozzle 4, and the filter nozzle 4 includes an air outlet pipe inserted inside the dust removal pipe 2. The air outlet pipe discharges gas to clean impurities on the pipe wall of the dust removal pipe 2.
[0027] Specifically, the filter nozzle 4 pressurizes the gas, increasing the intensity of the airflow, thereby effectively cleaning the carbon black on the inner wall of the dust removal pipe 2. The outlet pipe is cylindrical and extends into the interior of the dust removal pipe 2. Its surface is covered with evenly arranged outlet holes. The gas entering the filter nozzle 4 is ejected through the outlet holes in all directions, thereby expanding the gas spray range and improving the cleaning effect.
[0028] In the automatic cleaning device for dust removal pipes in this embodiment, an internal thread head 5 is provided on the side wall of the dust removal pipe 2, and the filter nozzle 4 also includes a fixed pipe located at the air inlet end of the air outlet pipe. The outer surface of the fixed pipe is provided with an external thread and is threadedly connected to the internal thread head 5.
[0029] Specifically, the diameter of the fixed tube is larger than that of the outlet tube, which facilitates the smooth insertion of the outlet tube into the dust removal channel 2. The fixed tube is connected to the internal thread 5 to achieve a tight connection between the filter nozzle 4 and the dust removal pipe 2, so as to prevent gas leakage or the diffusion of carbon black in the dust removal pipe 2 to the outside of the dust removal pipe 2.
[0030] Preferably, the filter nozzle 4 can be a threaded copper powder sintered filter element from the prior art.
[0031] In the automatic cleaning device for dust removal pipes in this embodiment, the connector assembly further includes a one-way valve 6, which is threaded to the outer end of the fixed pipe to achieve communication between the one-way valve 6 and the filter nozzle 4.
[0032] A one-way valve 6 is installed between the connecting pipe 3 and the filter nozzle 4 to prevent the airflow from flowing in the opposite direction, ensuring that all the airflow in the connecting pipe 3 enters the dust removal pipe 2 through the filter nozzle 4, thereby effectively cleaning the carbon black on the wall surface.
[0033] Specifically, the internal thread 5 is a nut located on the surface of the dust removal pipe 2, and a through hole for installing the filter nozzle 4 is opened on the side wall of the dust removal pipe 2. The nut is welded to the dust removal pipe 1 to ensure sealing.
[0034] The above-mentioned setup avoids carbon black leakage. The external thread of the fixed tube of the filter nozzle 4 is divided into two sections, which are respectively threaded to the nut and the one-way valve 6. The above structure simultaneously realizes the installation of the filter nozzle 4 on the dust removal pipeline 2 and the fixed connection between the one-way valve 6 and the filter nozzle 4. The structure is simple, easy to install, and convenient to disassemble, repair or replace the filter nozzle 4.
[0035] In addition, in this application, an internal thread 5 can be installed inside the side wall of the dust removal pipe 2, and a nut can be installed on the outside of the dust removal pipe 2, so as to be tightly connected to the filter nozzle 4 through the above-mentioned double internal thread structure.
[0036] In the automatic cleaning device for dust removal pipes in this embodiment, quick connectors 7 are provided at both ends of the connecting pipe 3, and the connecting pipe 3 is connected to the one-way valve 6 and the bypass pipe 1 respectively through the quick connectors 7 at both ends.
[0037] Specifically, the connecting pipe 3 is made of PU tubing, which has the advantages of being flexible and low-cost. It is easy to change the shape of the connecting pipe 3 as needed, and thus it is easy to connect and install it with the dust removal pipe 2 and the bypass pipe 1 through the quick connector 7.
[0038] In the automatic cleaning device for dust removal pipes in this embodiment, several connecting pipes 3 are evenly arranged along the length of the dust removal pipe 2. The other end of each of the several connecting pipes 3 is connected to a bypass pipe 1. One end of the bypass pipe 1 is closed, and the other end is connected to an air source.
[0039] Select appropriate intervals for installing connecting pipes 3 according to the length of dust removal pipe 2, so as to ensure effective cleaning of each section of dust removal pipe 2 connected by flanges at each position along the axis and improve the cleaning effect.
[0040] In the automatic dust removal pipeline cleaning device of this embodiment, a control component 8 for controlling the opening and closing of the air passage is provided between the bypass pipe 1 and the air source. The control component 8 includes a manual valve and a pressure regulating valve installed between the air source and the manual valve.
[0041] Specifically, the gas source uses compressed gas, and a pressure regulating valve is set to regulate the pressure of the compressed gas. The regulated gas enters the bypass pipe 1, and then enters the dust removal pipe 2 from different positions through various connecting pipes 3, one-way valves 6, and filter nozzles 4 to spray and clean the carbon black in the dust removal pipe 2. A manual valve is set up for emergency operation: in case of pneumatic system failure, power failure, or debugging, the valve status can be manually switched. At the same time, the gas source can be cut off during isolation maintenance, which is convenient for maintenance.
[0042] In the automatic dust removal pipeline cleaning device of this embodiment, the control component 8 further includes a pneumatic control valve. The pneumatic control valve is connected to the auxiliary machine system and then switches on and off according to the instructions of the auxiliary machine system to intermittently supply air to the bypass pipe 1.
[0043] A pneumatic control valve is installed to receive signals from the auxiliary system and drive changes in valve opening to automatically regulate flow, pressure, or temperature. This allows for control of the ventilation frequency as needed, enabling automated cleaning.
[0044] Based on the above structure, a bypass pipe 1 is installed on one side of the dust collection pipeline. The bypass pipe 1 can use a DN50 pipe as a compressed air float path, connected to the dust collection pipeline via a PU tube / one-way valve 6 / filter nozzle 4. A DN50 pneumatic control valve + pressure regulating valve + manual valve are installed at the control end of the bypass pipe 1 and connected to the auxiliary system. PLC control enables the side-blowing function to open for 10 seconds within 2 hours to clean the carbon black inside the pipeline. After the side-blowing blows up the carbon black adhering to the inner wall of the pipeline, the negative pressure suction generated by the dust collector at one end of the dust collection pipeline 2 draws the carbon black into the dust collector's recovery tank, achieving carbon black collection, reducing hazardous waste treatment costs, and facilitating secondary utilization.
