Abstract

The utility model discloses a water pipe furnace bridge, which is a supporting frame which is made from hollow pipes which are mutually connected, wherein the furnace bridge is wholly sealed and an access pipe is arranged. The furnace bridge of the utility model is used in boilers in particular constant pressure hot-water boilers, a water inlet pipe is communicated with a cold water pipe (tank), an outlet pipe is communicated with a water (heat) storage tank, water in the furnace bridge forms flow naturally due to temperature difference, thereby, the temperature of the furnace bridge can not be lifted too high always, water scale also can not be formed in a furnace bridge pipe, which greatly prolongs the service life of the furnace bridge, simultaneously, water of the water pipe furnace bridge is heated, heat is fully utilized, the heat exchange rate is improved, the water pipe furnace bridge is arranged on the supporting frame on the bottom of the boilers, and if the furnace bridge is damaged and needs replacing, the whole furnace bridge can be directly pulled out to replace wholly, which is convenient and rapid.

Description

The thermal arrest water hollow grate that circulates

Technical field

The utility model relates to field of boilers, specifically is a kind of boiler with the thermal arrest water hollow grate that circulates.

Technical background

The general fixed support grate that adopts such as present boiler, hot-water cooking stove, coal is stacked burning on grate, for durable these grates of anti-burning all are that solid zinc-iron foundry goods or thick reinforcing bar are made.In addition, also has a kind of counter-burning type boiler, adopt double-deck grate, its lower floor's grate is solid, the upper strata is then adopted water pipe to be fixedly welded on the inside of boiler body and is made grate, and purpose is the heat energy utilization that contacts up and down for this grate, owing to all be the zone of flame up and down, this grate water pipe is communicated with boiler water tank, play acceleration hot water, improve the effect of heat exchange, because temperature height in the pipe, circulation is slow, fouling is fast, and service time soon will be dead by dirt, needs to change again, influence the use of boiler, and change complex procedures.

The utility model content

The utility model just provides a kind of incrusted thermal arrest water hollow grate that circulates that is difficult for, and anti-burning is durable, and it is convenient to change.

The purpose of this utility model is achieved in that a kind of thermal arrest water described grate of hollow grate that circulates is the framework of being made by the hollow pipe that is interconnected, and the grate integral sealing is provided with opening.

Described framework comprises that at least one group is responsible for and connects the looped pipeline of being responsible for, and the turnover pipe is located on the person in charge.

The described at least one group of person in charge is parallel to each other, and looped pipeline connects the person in charge and is parallel to each other.

Be responsible for all right closed communicating for described at least one group, looped pipeline connects between being responsible for to be responsible for.

The utility model beneficial effect is: boiler especially uses the utility model grate in the normal-pressure hot-water boiler, its water inlet pipe is communicated with cold water pipe (case), outlet is communicated with storage (heat) water tank, water in the grate since temperature difference to concern that nature forms mobile, the temperature of grate can not be raised to very high all the time like this, just can in the grate pipe, not form incrustation scale yet, prolonged the service life of water pipe grate greatly; Water in this water pipe grate obtains heating simultaneously, and constantly circulation makes full use of heat, has improved rate of heat exchange; This water pipe grate places on the boiler bottom support, when needing to change if any damage, can directly whole grate be pulled out integral replacing, and is fast convenient.

The specific embodiment

Embodiment 1: with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the thermal arrest water hollow grate that circulates is the square planar framework of being made by the hollow pipe that interconnects, this square planar framework comprises that two parallel persons in charge 1 are responsible for the 1 several looped pipelines 2 that are parallel to each other with vertically being connected, and looped pipeline 2 is up big and down small tubular structure.Inner each hollow pipe of framework is interconnected, whole to outer closure, on being responsible for, have intake-outlet and be communicated with

water pipe

3,4, during use, the thermal arrest water hollow grate that circulates is placed boiler thorax bottom, stack coal or comburant on the grate, the water inlet pipe 3 on the water pipe grate is communicated with cold water pipe (case), and outlet pipe 4 is communicated with storage (heat) water tank.

Embodiment 2: with reference to Fig. 5, the thermal arrest water hollow grate that circulates is the circular frame of being made by the hollow pipe that interconnects, this circular frame comprises the closed circle person in charge 1 and is connected the looped pipeline of being responsible for 2, inner each hollow pipe of framework is interconnected, whole to outer closure, have water inlet pipe and water outlet pipe on main frame tube, the water inlet pipe 3 on the water pipe grate is communicated with cold water pipe (case), and outlet pipe 4 is communicated with storage (heat) water tank.

Claims

1. a thermal arrest water hollow grate that circulates, it is characterized in that: described grate is the framework of being made by the hollow pipe that is interconnected, and the grate integral sealing is provided with opening.

2. the thermal arrest water according to claim 1 hollow grate that circulates is characterized in that: described framework comprises that at least one group is responsible for and connects the looped pipeline of being responsible for, and the turnover pipe is located on the person in charge.
