Abstract
The utility model relates to a spiral-flow dirt removing device for a spherical filter screen, which is characterized in that a tangential direction water inlet pipe is arranged at the middle lower part of a barrel body; a spherical filter screen is transversely fixed between a water inlet pipe and a water outlet pipe in the barrel body; an umbrella-shaped dreg blocking cover is fixed in a cone body at the bottom of the barrel body; a dirt discharging pipe is fixed on the lower part of the barrel body. In use, water enters the barrel body from the tangential direction of the water inlet pipe, flows to the bottom of the cone body from top to bottom in a rotating way, then flows from bottom to top along the shaft line of the center of the barrel body and flows out along the water outlet pipe after filtered by the spherical filter screen. The filter screen of the utility model has the advantages of large water flowing section area, little resistance, little possibility of blocking and high efficiency, and is suitable for filtering water and oil which have pressure less than 1.6 MP.
Description
The utility model relates to a kind of eddy flow, sphere filter screen dirt separator, everyly all dirt separator must be installed in pipelines such as process water, hot-water heating, tap water processing.Existing dirt separator can be divided into single flow and whirlwind-type two big classes.The filter screen of single flow dirt separator has board plug type and floral tube formula, and the board plug type filter screen is in case obstruction is serious, and pressure reduction increases before and after it, and the filter screen distortion will lose filteration.Floral tube formula filter screen water flowing sectional area is little, is generally 1.25-1.8 times of dirt separator adapter cross section, and resistance is big, and the work of stopping up the cleaning filter screen easily is very frequent; Existing whirlwind-type dirt separator is not establish filter screen in dirt separator, utilizes the rotational flow of water to divide dried up middle foreign material, and the leaf in the water, weeds, plastic skin and so on gently float foreign material, are to be difficult to separate completely by eddy flow.In case eddy flow is undesired or blowdown is untimely, the effect of scrubbing will be lost.
The purpose of this utility model provides that a kind of filter screen water flowing sectional area is big, resistance is little, efficient is high, often do not clean filter screen, simple in structure, easy discharge assorted dirty eddy flow, sphere filter screen dirt separator.
Branch of the present utility model art scheme is achieved in that in the bottom to be that the position, outside middle and lower part of cone-shaped Cylinder cylindrical shell tangentially is provided with water inlet pipe, on the top of cylindrical shell and water inlet pipe reverse direction barrel, be provided with rising pipe, the sphere filter screen has been installed in the horizontal activity in the middle part of water inlet pipe and rising pipe in cylindrical shell, the bottom is provided with umbrella shape pushing off the slag lid in the cone of cylindrical shell bottom, the top of cylindrical shell is provided with the insurance flange, vapor pipe is housed on it, the bottom of cylindrical shell is provided with blow-off pipe, is associated with bypass pipe and by-pass valve outside cylindrical shell between water inlet pipe and the rising pipe.
Excellent beneficial effect of the present utility model is: owing to adopted the cyclonic separation principle to make foreign material to bottom deposit, so foreign material are difficult to enter filter screen in the water, in servicely need clean filter screen hardly 1..2. sphere filter screen water flowing sectional area is big, resistance is little, the water flowing area is 4-5 times that take over, and water resistance is 0.01-0.02MP, is difficult for stopping up the efficient height.3. it is reliable to filter assorted dirt, and disassembly, cleaning are convenient.4. just in case filter screen stops up seriously, and removable loam cake cleans filter screen, the cycle of generally dismantling is very long.5., foreign material are discharged in case the sphere filter screen stops up seriously, can open by-pass valve, closes water intaking valve, opens wash water valve, carries out back flushing.
Accompanying drawing 1 is a structure cross-sectional schematic of the present utility model, and accompanying drawing 2 is A among Fig. 1-A sectional view, and accompanying drawing 3 is taken over synoptic diagram for dirt separator.
Tell about embodiment of the present utility model below in conjunction with accompanying drawing: eddy flow, sphere filter screen dirt separator, comprise flange 1, cylindrical shell 2, sphere filter screen 3, umbrella shape pushing off the slag lid 4, water inlet pipe 5, rising pipe 6, blow-off pipe 7, vapor pipe 8, cylindrical shell 2 is a bottom cone-shaped Cylinder, outside middle part at cylindrical shell 2 tangentially is provided with water inlet pipe 5, its import and cylindrical shell horizontal section tangentially are arranged, on the top of cylindrical shell 2 and water inlet pipe 5 reverse direction barrels, be provided with rising pipe 6, filter screen 3 has been installed in the horizontal activity in middle part of water inlet pipe 5 and rising pipe 6 in cylindrical shell 2, filter screen 3 is a sphere hard net, be that boring is made on casting or the stamping parts, the top of cylindrical shell 2 is provided with insurance flange 1, and vapor pipe 8 is housed on it, the cylindrical shell bottom is provided with blow-off pipe 7.In use, water tangentially enters cylindrical shell 2 rotational flows by water inlet pipe 5.Rotating liquid rotates to the cone-shaped body bottom from top to bottom along barrel, and then flows from bottom to top along the cylindrical shell center along axis, through flowing out along rising pipe 6 behind the sphere strainer filtering.Foreign material sink to the cone base deposition of cylindrical shell 2 in the water along barrel under the effect of rotary centrifugal force.Take away for the foreign material that prevent to stockpile are risen by mobile water upwards, be provided with umbrella shape pushing off the slag lid 4 in the cone bottom, adorned wash water valve on blow-off pipe 7, wash water valve is ball valve or dish valve, opens the foreign material that wash water valve can be drained and be stockpiled.Outside cylindrical shell 2, be provided with bypass pipe 9 and by-pass valve 10 between water inlet pipe 5 and the rising pipe 6,, can open by-pass valve 10, close water intaking valve, open wash water valve, carry out back flushing, foreign material are discharged in case the sphere filter screen stops up seriously.The general periodic blow down of this dirt separator only need be opened wash water valve, need not do other any operation, is applicable to pressure≤1.6MP, and the water filtration and the oil of temperature≤200 ℃ are filtered.Screen grid is generally 4MM, also to make according to user's needs.
