Abstract

The utility model discloses a heating, dredging and anti-blocking device for a tap water pipeline, which can prevent the tap water pipeline from being frosted, frozen and blocked in cold seasons, and realize unobstructed water supply of the tap water pipeline. The device comprises a steel pipeline, wherein the steel pipeline is coated with an aluminium foil, the aluminium foil is wound by a heating cable, and the heating cable is coated with a glass wool insulating layer.

Description

A kind of water supply pipe heating dredging anti-block device

Technical field

The utility model relates to a kind of pipeline heating dredging anti-block device, is specifically related to a kind of water supply pipe heating dredging anti-block device.

Background technique

In the northern China rural area, water supply pipe was easily endured cold and freeze to be stopped up cold season, caused people's water intaking difficulty of living.Adopt at present usually the mode of open firing to come the melt water dredging pipeline in order to water intaking, this method not only efficiency not high, also waste energy, and befouling environment.

The model utility content

For the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of water supply pipe heating dredging anti-block device, can prevent the obstruction of freezing of enduring cold of water supply pipe cold season, realizes the unobstructed water supply of water supply pipe.

The utility model adopts the basic conception of technological scheme to be: comprise steel pipe, at described steel pipe, be wrapped with aluminium foil, outside this aluminium foil, be wound around heating cable, at this heating cable outer wrapping glass wool thermal insulation layer.

Preferably, described delivery (pipe) line heating dredging anti-block device also comprises: temperature transducer, in order to detect the temperature of steel pipe outer wall; Temperature controller, according to the break-make of the ac power supply of the described heating cable of output numerical control of this temperature transducer.

The beneficial effects of the utility model are, heating cable directly is fixed on to the wall of steel pipe by aluminium foil, the coated outside thermal insulation layer, whole device moves under the monitoring of temperature controller, in pipe, the temperature controlled fluctuation in certain scope all the time of tap water, guarantee that pipeline can not freeze, and realizes the unobstructed water supply of water supply pipe, prevent the pipeline bursting by freezing, guarantee the delivery (pipe) line security of system.

The accompanying drawing explanation

Fig. 1 is the structural representation of water supply pipe heating dredging anti-block device, and Fig. 2 is the control block diagram of water supply pipe heating dredging anti-block device.

In figure: the 1-steel pipe; The 2-heating cable; The 3-glass wool; The 4-temperature transducer; The 5-temperature controller; The 6-ac power supply.

Embodiment

As shown in Figure 1 and Figure 2, at steel pipe 1, be wrapped with aluminium foil, be wound around heating cable 2 outside this aluminium foil, at heating cable 2 outer wrapping glass wool 3 thermal insulation layers, also should outermost surface swathe glass cloth and outside be coated with fireproof paint.Temperature transducer 4 is in order to detect the temperature of steel pipe outer wall, and temperature controller 5 is according to the break-make of the ac power supply 6 of the output numerical control heating cable 2 of temperature transducer 4.In the situation that heating cable 2 energisings, the interior wall temperature of steel pipe 1 raises gradually, when wall temperature reaches 6.5 ℃ of the upper limiting temperatures of temperature controller 5, temperature controller 5 cuts off the ac power supply 6 of heating cable 2, wall temperature starts to descend thereupon, until wall temperature is while dropping to 5.5 ℃ of the lower limit temperatures of temperature controller 5, temperature controller 5 recloses the ac power supply 6 of heating cable 2, and wall temperature restarts to raise.In this process, the wall temperature kept stable.In pipe, the temperature controlled fluctuation in certain scope all the time of tap water, guarantee that pipeline can not freeze.

Claims

1. a water supply pipe heating dredging anti-block device, comprise steel pipe, it is characterized in that, at described steel pipe, is wrapped with aluminium foil, is wound around heating cable outside this aluminium foil, at this heating cable outer wrapping glass wool thermal insulation layer.

2. water supply pipe heating dredging anti-block device according to claim 1, is characterized in that, described device also comprises: temperature transducer, in order to detect the temperature of steel pipe outer wall; Temperature controller, according to the break-make of the ac power supply of the described heating cable of output numerical control of this temperature transducer.
