Fig. 2 is an installation schematic diagram of the filter net of the L-shaped filter of the present invention.
In the figure: 1. a filter body; 2. a water outlet pipe; 3. a water inlet pipe; 4. a flange opening; 5. a flange blind plate; 6. a drain pipe; 7. an electric blow-down valve; 8. a pressure sensor; 9. a control box; 10. and (4) a filter screen.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, an L-shaped filter, includes filter body 1 and the filter screen 10 of tube-shape, the one end of filter body 1 is sealed, other end horizontal connection outlet pipe 2, inlet tube 3 is connected perpendicularly on the top of filter body 1, the bottom of filter body 1 is equipped with the flange opening 4 that corresponds with inlet tube 3, the shutoff of flange opening 4 flange joint flange blind flange 5, flange blind flange 5 middle part fixed connection drain pipe 6, be equipped with electronic blowoff valve 7 on the drain pipe 6, filter screen 10 is installed in filter body 1, and its bottom and flange blind flange 5 contact are connected, all be equipped with pressure sensor 8 on inlet tube 3 and the outlet pipe 2, fixed connection control box 9 on the outer wall of filter body 1. The pressure sensor 8 is electrically connected with a PLC (programmable logic controller) in the control box 9, and the PLC is electrically connected with the electric blowdown valve 7. The ends of the inlet pipe 3 and the outlet pipe 2 may be flanged or threaded, and may be flanged or threaded to the pipe, or may be welded to the pipe, increasing the selectivity of the installation operation, the flanges being shown in fig. 1 and 2.
The top of filter screen 10 is higher than the top setting of filter body 1, is located inlet tube 3, flange opening 4 and inlet tube 3 can carry out spacing fixed with filter screen 10. The inlet tube 3 is unanimous with the pipe diameter of outlet pipe 2, and all is less than the external diameter of filter body 1, ensures that the inflow can flow from outlet pipe 2 smoothly, and filter body 1 has certain water storage capacity, avoids storing up impurity discharge flow because of filter screen 10 and reduces the pressure damage that causes filter body 1.
The utility model discloses a theory of operation does: the water inlet pipe 3 is arranged on a vertical pipe of the heating and ventilation system, the medium flows from top to bottom, enters the filter screen 10 of the filter body 1 through the water inlet pipe 3 and is filtered by the water outlet pipe 2, the impurities are retained in the cylindrical filter screen 10 and are gradually accumulated at the bottom under the gravity action of the impurities, when the impurity reaches a certain amount, the flowing resistance of the medium in the filter screen 10 is increased, the pressure sensors 8 on the water inlet pipe 3 and the water outlet pipe 2 send the detected pressure signals to the PLC controller in real time, the PLC controller analyzes the pressure difference between the two, when the pressure difference of the pressure corresponding to the pressure signal is detected to increase and can be set in advance, and the set pressure difference is reached, the PLC sends a signal to the electric blow-down valve 7, the electric blow-down valve 7 is opened, impurities in the filter screen 10 are carried by the flowing medium and discharged from the water discharge pipe 6, so that automatic pollution discharge is realized; when the pressure difference is continuously increased, the PLC sends out an alarm signal, and a buzzer alarm mode can be adopted to prompt a user that the filter screen 10 needs to be replaced.
When the bolt connection or welding mode is adopted, an elbow, two flanges and a bolt in the existing installation mode are omitted, when the flange connection mode is adopted, the connection of an elbow is also reduced, the installation steps are reduced, the connection mode can be selected from thread connection, flange connection or welding, and the operation selectivity is increased; one elbow is simplified, and the resistance of a system pipeline is reduced; the operation and maintenance difficulty can be reduced, and automatic pollution discharge is realized.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
