Abstract

The utility model relates to an automatic filtering feculence drainer used for a central heating system, which overcomes the defects that the existing domestic filter in the prior art needs artificial feculence drainage for many times, the operation is inconvenient, and the feculence drainage effect is difficult to ensure in operation. A water inlet pipe 1 is communicated with a water return pipe 5 by a feculence drainage pipe 7 to form a feculence drainage channel, and the feculence drainage pipe 7 is provided with a feculence drainage valve 6 which is controlled by a control device 4. During feculence drainage, the control device 4 opens the feculence drainage valve 6, and the water current in the water inlet pipe 1 is led to the water return pipe 5 by the feculence drainage pipe 7 to carry out the feculence drainage. After the feculence drainage, the feculence drainage valve 6 is closed, and the normal heat supply is carried out. Because the utility model adopts the technical scheme that the utility model utilizes the water current power of the heating system to directly flush, wash and drain feculence which is filtered, the heating system can not be blocked, the feculence does not accumulate and adhere, and the heating equipment and measuring instruments are effectively guaranteed to normally work.

Description

The automatic fitration excretion machine

(1) technical field under:

The utility model relates to a kind of automatic fitration excretion machine that is used for the family with central heating system.

(2) background technology

Concerning central heating system, owing to be subjected to the influence of the clean degree of treatment in heating system water source, and owing to reasons such as wearing and tearing, the burn into of pipeline, pipe fitting, user's heat dissipation equipment are aging, can make inevitably in the current of heating system dirt to occur.This dirt gathering and adhering to user's indoor heating equipment, and heat transfer condition is worsened, and causes heating quality to descend.Particularly when dirt is flowed through gauge table, also can gather, adhere to even stop up the heating metering instrument, cause the gauge table metering inaccurate, thereby cause user's heating system cisco unity malfunction.

Place, water source at heating system in the prior art is provided with the concentration filter blowdown apparatus, in each user's porch the family filter is set.The family is made up of the plug of skew T, screen pack and inclined tube bottom with filter, is arranged on usually on user's the heating inlet channel.The inclined tube of skew T has formed and has held dirty pipe, and dirt in the water pipe that heats at ordinary times and impurity are filtered net and intercept in holding dirty pipe, and the plug that need regularly open under the inclined tube is got rid of dirt.Because the dirt in the heating system produces at random, and it is limited to hold the volume of dirty pipe, and the unimpeded and filth-discharging effect in order to ensure pipeline in a heating period, need repeatedly carry out blowdown.Yet this periodical blowdown need manually be finished, and the bottom blow-down plug that particularly needs specific purpose tool just can open filter carries out blowdown, inconvenient operation, and be difficult to guarantee filth-discharging effect.

(3) summary of the invention

For overcome exist in the prior art need carry out repeatedly artificial blowdown with filter to the family, inconvenient operation is difficult in the enforcement guarantee the deficiency of filth-discharging effect the utility model proposes a kind of automatic fitration excretion machine.

The purpose of this utility model is achieved in that by blow-off pipe inlet channel is connected with water return pipeline, makes it to form the drain outlet, and the blowoff valve by controller control is housed on this drain outlet.When blowdown, by controller blowoff valve is opened, the current of water supply line are introduced water return pipeline by blow-off pipe, utilize the flow dynamic of heating system self, directly wash away the dirt that is filtered with dispatch, carry out blowdown.

The technical scheme that the utility model adopted can be introduced water return pipeline with the current of inlet channel, utilize the flow dynamic of heating system self, directly wash away the dirt that is filtered with dispatch, realization is to the automatic fitration dirt and automatic periodical blowdown of user's heating system, improved filtration filth-discharging effect to user's heating system, thereby guarantee that the indoor heating system is not stopped up, dirt does not gather, adhere to, make user's indoor heating equipment working properly, particularly make family heating metering instrument long-life ground operate as normal.

(5) specific embodiment

Embodiment one

Present embodiment is between the feed pipe 1 of user's heating and return pipe 5 blow-off pipe 7 to be set, and blowoff valve 6 is set on blow-off pipe 7, open and close by controller 4 control blowoff valves 6, make the current of water supply line 1 enter return pipe 5 through blow-off pipe 7, utilize the flow dynamic of heating system self, directly wash away the dirt that is filtered with dispatch.

Present embodiment comprises feed pipe 1, bevel arm piece 2, screen pack 3, controller 4, return pipe 5, blowoff valve 6 and blow-off pipe 7.In concrete the enforcement, the plug of bevel arm piece of the prior art 2 bottoms is got through, water pipe is communicated with bevel arm piece 2 with return pipe 5, makes and forms blow-off pipe 7 between feed pipe 1 and the return pipe 5.

Blowoff valve 6 is installed on blow-off pipe 7 optional positions, and its Control Shaft and controller 4 join.Controller 4 is by its built-in micro machine, the control that can regularly open or close blowoff valve 6: during blowdown, blowoff valve 6 is opened, utilized the flow dynamic of heating system self, make the current of feed pipe 1 enter return pipe 7 through blow-off pipe 7; After finishing blowdown operation, close blowoff valve 6 again, carry out normal heat supply.

Embodiment two

Present embodiment comprises feed pipe 1, screen pack 3, controller 4, return pipe 5, blowoff valve 6 and blow-off pipe 7.In concrete the enforcement, original bevel arm piece 2 is removed, installed additional a blow-off pipe 7 between water inlet pipe 1 and return pipe 5, the two ends of this blow-off pipe 7 are connected with return pipe 5 with water inlet pipe 1 respectively, make it to form the drain outlet, and the blowoff valve 6 by controller 4 controls is housed on blow-off pipe 7.

Claims

1. an automatic fitration excretion machine comprises feed pipe (1), bevel arm piece (2), screen pack (3), return pipe (5), blowoff valve (6), it is characterized in that: also include blow-off pipe (7) and controller (4); And blow-off pipe (7) is installed between water inlet pipe (1) and the return pipe (5), and two ends are connected with return pipe (5) with water inlet pipe (1) respectively; Controller (4) is installed on the blow-off pipe (7).
