Description

Technical Field

[0001] This utility model relates to the field of coating machine cleaning technology, and in particular to a coating grease backflushing oil mist collection system. Background Technology

[0002] A coating machine is a highly efficient, energy-saving, safe, and clean mechatronic device capable of organic film coating, water-soluble film coating, and sustained-release / controlled-release coating of tablets, pills, and candies. It is suitable for the pharmaceutical, chemical, and food industries. In existing technologies, after coating, residual material is back-blown through compressed air through the grease pipe to a spray tank and then directly discharged into the workshop. This results in excessive smoke in the workshop, affecting the environment, disturbing operators of auxiliary equipment, and triggering smoke alarms. Utility Model Content

[0003] The purpose of this invention is to provide a backflushing oil mist collection system for coated greases, thereby solving the aforementioned problems in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a coating grease backflushing oil mist collection system, comprising a coating machine, a rotor pump, a filter, a spray can, a ducted ventilation fan, and an oil mist purifier. The exhaust pipe at the top of the spray can is sequentially connected to the ducted ventilation fan and the oil mist purifier. A pneumatic bottom valve is installed at the bottom outlet of the spray can. The inlet of the rotor pump is connected to the pneumatic bottom valve through the filter. The rotor pump is connected to the coating machine and the backflushing pipeline, respectively. The outer end of the backflushing pipeline is connected to a compressed air source.

[0006] Furthermore, a manual ball valve, a pressure reducing valve, and a pneumatic ball valve are sequentially installed on the backflush pipeline.

[0007] Furthermore, the working pressure range of the pressure reducing valve is 0.15-1 MPa.

[0008] Furthermore, the filter is a Y-type filter.

[0009] Furthermore, the manual ball valve is normally open.

[0010] Furthermore, the air volume of the ducted ventilation fan is 1000m³. 3 / h, static pressure is 380pa, power is 130w.

[0011] Furthermore, the processing air volume of the oil mist purifier is 1500m³. 3 / h, with an air intake diameter of 150mm and a power of 1.5kw.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model's coated grease backflushing oil mist collection system, by setting up a rotor pump, filter, spray can, ducted ventilation fan, and oil mist purifier, can backflush residual grease into the spray can through the backflushing pipeline, effectively preventing clogging of the oil spraying pipeline. During backflushing, due to the high temperature of the grease, a large amount of oil mist is generated. By setting up the ducted ventilation fan and oil mist purifier, the oil mist can be purified and discharged. This solves the problem in the prior art that the oil mist generated when backflushing the coated grease pipeline cannot be collected and treated. The overall structure is reasonably designed, easy to use, and highly practical. Attached Figure Description

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figure 1 As shown, the coating grease backflushing oil mist collection system of this embodiment includes a coating machine 10, a rotor pump 4, a filter 5, a spray can 7, a ducted ventilation fan 8, and an oil mist purifier 9. The exhaust pipe of the top end cap of the spray can 7 is connected in sequence to the ducted ventilation fan 8 and the oil mist purifier 9. The ducted ventilation fan 8 can draw in oil mist, and the oil mist purifier 9 is used to filter and purify the oil mist. A pneumatic bottom valve 6 is installed at the bottom outlet of the spray can 7 to control the discharge of the spray can 7.

[0021] In this embodiment, the feed inlet of the rotor pump 4 is connected to the pneumatic tank bottom valve 6 via a filter 5. The filter 5 can effectively filter grease impurities. The rotor pump 4 is also connected to the coating machine 10 and the backflush pipeline. At this time, the grease is transported to the coating machine 10 through the rotor pump 4. Furthermore, the outer end of the backflush pipeline is connected to a compressed air source. A manual ball valve 1, a pressure reducing valve 2, and a pneumatic ball valve 3 are sequentially installed on the backflush pipeline. The manual ball valve 1 has an on / off function for easy inspection and maintenance. The pressure reducing valve 2 can reduce the compressed air pressure. The pneumatic ball valve 3 is used for automatic on / off control of the air intake. Specifically, the working pressure range of the pressure reducing valve 2 is 0.15-1 MPa.

[0022] Preferably, filter 5 is a Y-type filter 5, wherein the Y-type filter 5 can effectively remove solid impurities from grease.

[0023] In this embodiment, the air volume of the duct-type ventilation fan 8 is 1000m³. 3 With a static pressure of 380 Pa and a power of 130 W, it can meet the ventilation needs of large spaces and has a high energy efficiency ratio; the oil mist purifier 9 has a processing air volume of 1500 m³ / h. 3 With an air intake diameter of 150mm and a power of 1.5kw, it can ensure a highly efficient oil mist purification effect.

[0024] In this embodiment, during normal operation of the coating machine 10, the grease is drawn from the spray tank 7 by the rotor pump 4, passes through the filter 5 to remove impurities, and is then transported to the coating machine 10 for spray coating. When the coating machine 10 completes its coating task and requires pipe cleaning or grease residue treatment, the system initiates a backflushing procedure. At this time, the manual ball valve 1 is normally open, and the duct ventilation fan 8 and oil mist purifier 9 automatically start to prepare for the suction and purification of oil mist. Subsequently, the pneumatic ball valve 3 and the pneumatic tank bottom valve 6 are opened to compress air. Compressed air enters the rotor pump 4 through manual ball valve 1, pressure reducing valve 2, and pneumatic ball valve 3, forming a powerful backflush airflow. This airflow pushes the residual grease in the grease pipeline, through filter 5 and pneumatic tank bottom valve 6, and finally into the spray tank 7. At this time, due to the strong push of the grease by the compressed air and the high temperature of the grease during backflush, a large amount of oil mist is generated. The generated oil mist is sucked in by the duct ventilation fan 8 and efficiently filtered and purified by the oil mist purifier 9. The purified air is safely discharged, avoiding the pollution of the workshop environment by the oil mist.

[0025] The coating grease backflushing oil mist collection system in this embodiment effectively reduces oil mist pollution to the workshop air through the purification effect of the oil mist purifier, protecting the health of operators. At the same time, the automatic start and stop function of the duct ventilation fan realizes the rational use of energy and reduces energy consumption. Furthermore, the backflushing process is highly automated, requiring only simple operation to start the entire process. The precise control of the pneumatic ball valve and pneumatic tank bottom valve ensures the stability and reliability of the backflushing process. In addition, through effective grease residue treatment and oil mist purification, the impact of grease contamination on the quality of coated products is avoided, improving the overall quality and market competitiveness of the products.

[0026] In actual testing, after the coating production was completed, the coating grease backflushing oil mist collection system of this embodiment was activated. No oil mist appeared on site, and the smoke alarm did not sound. The site environment was effectively improved and met the environmental requirements.

[0027] The oil mist collection system for backflushing coated greases of this invention solves the problem in the prior art that the oil mist generated during backflushing of coated grease pipelines cannot be collected and treated. The overall structure is reasonably designed, easy to use, and highly practical.

[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
