Description
Technical Field
The utility model belongs to the technical field of the circulating water is defeated joins in marriage and energy-conserving, a low resistance water filter equipment is related to.
Background
The energy consumption of the circulating water transmission and distribution system is huge, and factors influencing the energy consumption of the circulating water transmission and distribution system are many. In order to save the energy consumption of a circulating water transmission and distribution system, the reduction of the equipment resistance in the circulating water transmission and distribution process is imperative. The resistance of the water filter, which is one of the main devices of the circulating water distribution system, is an important factor influencing the energy consumption of the circulating water distribution system.
In prior art's circulating water transmission and distribution system, adopt Y type filter to filter at present mostly, traditional Y type filter has advantages such as small, easy installation, but also has a great deal of problems: (1) Generally, a plane type filter screen is adopted, and the power consumption of the water pump is higher due to small filter area, higher water flow speed and large resistance; (2) The sewage collecting volume is small, and the filter screen is easy to block, so that the flow of a water system is reduced, and the normal use of subsequent water utilization equipment is influenced; (3) The flange cover must be disassembled, the dirt is periodically removed, and the maintenance workload is large. Therefore, the low-resistance filter is adopted to replace the traditional Y-shaped filter, and the low-resistance filter has good research value in the field of circulating water distribution systems.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model provides a resistance is low, the filter effect is good, and can prevent that the filter screen from blockking up, hold the sediment space big, arrange sediment convenience, long service life's low resistance water filter equipment.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a low resistance water filter, includes barrel, filter screen, the dirty nozzle stub of collection, blowdown ball valve, and there is the opening at the barrel both ends and through flange and pipe connection, and the nozzle stub of intaking, the nozzle stub of play water branch are located in the barrel both ends, filter screen are located the barrel, and the dirty nozzle stub of collection passes through the flange to be connected the external blowdown ball valve of dirty nozzle stub of collection with the blowdown ball valve. The filter screen is in a herringbone or conical structure and is fixed on the cylinder body by welding; the two sewage collecting short pipes are divided into two parts and are symmetrically arranged on two sides of the cylinder body; the central line of the short sewage collecting pipe and the central line of the cylinder form 70-80 0 And (4) an included angle.
The mesh specification of the filter screen is 15-20 meshes, and the material is 304 stainless steel.
Compared with the prior art, the beneficial effects of the utility model are that: because the herringbone or conical filter screen is adopted, the three-dimensional slope filter screen is easier to wash than the traditional plane filter screen, the problem that the filter screen is easy to block can be solved by utilizing the washing force of inflow water, and the impact resistance of water is reduced to realize energy conservation; the two-way sewage collecting short pipe with inclination is adopted to temporarily store the sediment, so that the slag containing space is large, the slag discharging is convenient, and the manual sewage discharging ball valve can be used for discharging the sewage regularly, so that the purpose that the transmission and distribution system is in a low-resistance state for a long time, the running flow is not influenced, and the purposes of energy conservation and safe running of the circulating water transmission and distribution system are realized. The utility model discloses can replace the Y type filter of water pump or other equipment entry, greatly reduced more than the system water resistance, the filtering resistance is than a little order of magnitude of Y type filter resistance, has good popularization and application and worth in circulating water transmission and distribution system field.
