Preferably, in the dust removing system of the present utility model, a valve is further included in the gas line, and the valve may be used to adjust the pressure value and flow rate in the line. In the event of an abnormality, communication with the outside air may also be blocked by closing the valve. In the utility model, the valve can be a manual valve, for example, a ball valve or a common stop valve can be selected according to actual conditions; various automatic valves are also possible, such as solenoid valves.
Preferably, in the dust removing system of the present utility model, the check valve is located inside the filling machine, so as to prevent the external environment from polluting the check valve and causing pollution of products.
In the dust removing system, the adopted valve can be positioned in the filling machine and at the upstream of the one-way valve, so that the communication with the outside can be blocked rapidly and effectively when an abnormal state occurs, and the product is ensured not to be polluted.
In the dust removal system of the present utility model, a vacuum gauge is further included for monitoring the pressure conditions in the pipeline.
Preferably, in the dust removal system of the present utility model, a vacuum gauge is used on the filter.
In the dust removing system of the present utility model, the vacuum apparatus used may be any commercially available apparatus that provides negative pressure, such as a vacuum cleaner, an industrial exhaust fan, a vacuum pump, etc.
In the dust removing system of the present utility model, the filter is used for removing metal particles such as aluminum scraps in the exhaust gas, preventing air pollution, and the filter element should be replaced and/or the aluminum scraps should be removed at regular time.
In the dust removing system of the utility model, the adopted air extraction pipeline inside the filling machine with a smooth inner surface is used for connecting the solid particle collecting device and the one-way valve, and the air pipeline outside the filling machine can be a common air pipeline, and the difference between the two is that the inner surface of the air extraction pipeline inside the filling machine is smooth and is not easy to deposit dust, and the material is not dust and accords with the related requirements of GMP.
The external air pipeline of the filling machine is used for connecting all parts positioned outside the filling machine, and the size and the diameter of the pipeline can be adjusted according to actual conditions.
Under the condition of opening and closing the dust removing system, the dust removing system is tested according to the GB/T16292-2010 pharmaceutical industry clean room (area) suspended particle testing method. Experimental results prove that the device can obviously reduce the concentration of particles in the filling machine and ensure the quality of products.
The beneficial effects of the utility model are as follows: the filling machine can occupy the internal space of the filling machine less, can effectively reduce the dust particle number in the filling machine, reduce the pollution to the environment and products, and improve the yield of the products while improving the stability of the equipment.
