Abstract
The utility model provides a go up water -locator for filter, its including: one is used for the inlet tube of being connected with the inlet channel, a plurality of branch pipe, a connecting piece, the bottom of inlet tube with the top of connecting piece communicates each other, the lateral wall of connecting piece is equidistant has seted up a plurality of connecting piece through -holes, each the connecting piece through -hole is respectively with one the branch pipe intercommunication, follow at the top of branch pipe the axis direction of branch pipe is equidistant sets up a plurality of drainage holes line. The utility model has the advantages of the reduction rivers prevent to the impact of filter material that the filter material from getting into the inlet channel.
Description
Technical field
The utility model relates to a kind of upper water distributor for filter.
Background technology
The upper water distributor design of existing filter mostly is stainless steel baffle-type upper water distributor, only plays a very little barrier effect to feed water flow, allows current be unlikely and directly impact filtrate, but make current uniform again by the bounce-back after impact baffle plate.And when filter needs backwash time, the current of filter bottom enter in the process of water inlet pipe in rising, filtrate is easily passed through from the through hole of baffle plate, enters inlet channel.
Utility model content
The technical problems to be solved in the utility model is the defect that the upper water distributor in order to overcome existing filter effectively can not slow down that current enter water inlet pipe to filtrate when the impact of filtrate and backwash, provides a kind of upper water distributor for filter.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of upper water distributor for filter, it includes: one for the water inlet pipe be connected with inlet channel, some arms, a connection piece, its feature is, the bottom of described water inlet pipe and the top of described connector are interconnected, the sidewall of described connector is equally spaced offers some connector through holes, each described connector through hole is communicated with arm described in respectively, and some drainage hole rows are offered along the axis direction of described arm in the top of described arm.After current enter from water inlet pipe, enter each arm uniformly, then discharge from the drainage hole rows on each arm top.Because drainage hole rows is arranged on the top of each arm, decrease current and discharge for the impact of filtrate from arm bottom.
Preferably, the quantity of described arm is six.
Preferably, each described arm all has three described drainage hole rows.
Preferably, the angle described in three between drainage hole rows and horizontal direction is respectively 30 °, 90 °, 150 °.
Preferably, each described drainage hole rows all has 7 conduction holes.
Preferably, between described water inlet pipe and described connector be clamp connection.
Preferably, between described connector with described arm for being threaded.
Preferably, the sectional area of described arm is less than the sectional area of described water inlet pipe.This makes water inlet pipe have enough water yields to enter each arm.
Preferably, the area sum of described conduction hole is identical with the sectional area of described water inlet pipe.This makes upper water distributor the water inlet of water inlet pipe to be discharged from each arm in time fully.
Preferably, described arm adopts stainless steel.
Positive progressive effect of the present utility model is: decrease the impact of current for filtrate in filter, when it also avoid backwash, bring filtrate into inlet channel.

Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Embodiment
Understood incorporated by reference to Fig. 1-2, a kind of upper water distributor for filter, it includes: for water inlet pipe 11, connector 12 and the arm 2,3,4,5,6,7 be connected with inlet channel.The bottom of water inlet pipe 11 and the top of connector 12 are interconnected, and the sidewall of connector 12 is equally spaced offers six connector through holes, and arm 2,3,4,5,6,7 is communicated with connector 12 after being connected with a fitting through hole.Be clamp connection between water inlet pipe 11 and connector 12, for being threaded between connector 12 with arm 2,3,4,5,6,7.Arm all adopts stainless steel.
Understood incorporated by reference to Fig. 1, each arm all has three drainage hole rows, such as, arm 2 top along the axis direction of arm 2 offer 3 drainage hole rows 21,22,23, three drainage hole rows 21,22, angle between 23 and horizontal direction is respectively 30 °, 90 °, 150 °.Each drainage hole rows all has 7 conduction holes, and such as, drainage hole rows 21 is made up of 7 conduction holes 210,211,212,213,214,215,216.
Understood incorporated by reference to Fig. 1, the sectional area of arm 2,3,4,5,6,7 is all less than the sectional area of water inlet pipe 11, and the area sum of all conduction holes is identical with the sectional area of water inlet pipe 11.
Understood incorporated by reference to Fig. 1, operation principle of the present utility model is:
After current enter arm 2,3,4,5,6,7 from water inlet pipe 11, current can not directly flow out from the bottom of each arm, and after filling up whole arm, can discharge from each conduction hole of the first half of arm.Due to the stop of current bottom arm, potential energy weakens, therefore, less for the impact of filtrate when current are discharged from conduction hole;
When needs backwash time, current enter arm from conduction hole after upwards covering conduction hole gradually from the bottom of filter, then enter water inlet pipe 11 from each arm.Because current are not directly enter arm from the bottom of arm, enter the possibility of arm because this reducing filtrate.
When needs are emptying, current can flow out from the end small hole at bottom part of each arm, can not residual liquid in arm.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
