Abstract

The utility model relates to an atmospheric pressure briquette boiler. The utility model is characterized in that the lower part of a boiler body is a rectangular combustion chamber, and the front part of a fire grate 3 is provided with a flat plate 4 which is used for placing briquette and a briquette pushing plate 7. Under the drive of a connecting rod type driving device, the briquette pushing plate 7 pushes the briquette on the flat plate 4 to the fire grate 3 of the middle part of the combustion chamber. The back part of the fire grate 3 is provided with an ash cleaning door 9 which can conveniently add the new briquette into the boiler and clean the ash at any time. The utility model exerts the advantage of briquette combustion, and solves the defect in the prior art that the briquette is inconvenient to add and the ash is inconvenient to clean simultaneously.

Description

The normal pressure molded coal boiler

What the utility model related to is a kind of normal-pressure hot-water boiler of briquet.

A variety of normal-pressure boilers are arranged in the prior art, and its structure constitutes and has nothing in common with each other, and its oneself characteristics are respectively arranged.The normal-pressure boiler that uses moulded coal is also arranged in the prior art, as the disclosed pressure-less boiler of CN96211786, including structures such as body of heater, combustion chamber constitutes, fire grate in its combustion chamber is to be made of coaster formula fire grate structure, promptly the bottom in the combustion chamber is provided with track, be equipped with coaster formula fire grate in orbit, moulded coal is placed on this coaster fire grate, push in the combustion chamber and burn, this structure is also inconvenient in the use, particularly coal is very inconvenient, generally can only be that disposable burning is used, and continuous coal and deashing must be pulled out coaster formula fire grate in stove and just can be carried out outward.

The purpose of this utility model provides the normal-pressure hot-water boiler of briquet a kind of simple in structure, easy to operate.

The technical solution of the utility model is, comprise water jacket furnace, be opened in the combustion chamber in the body of heater bottom, the normal-pressure hot-water boiler that fire grate constitutes, it is characterized in that, the bottom of body of heater 1 is a rectangle, promptly constitute rectangle combustion chamber 2, in combustion chamber 2, establish casting furnace grate 3, leading section connection at fire grate 3 is provided with a flat board 4 that is used to put moulded coal 10, flat board 4 is offered fire door 5 on the upper surface of rectangle combustion chamber 2 to coalingging, on the flat board 4 of coalingging, erect and be provided with a movably coal-pushing plate 7, coal-pushing plate 7 is done under the drive of its transmission device-link-type transmission device and is moved forward and backward, the moulded coal that is housed on dull and stereotyped 4 is advanced on the fire grate 3 of middle part, combustion chamber, on a side sidewall of fire grate 3 lower combustion chamber 2, offer shutter 8, on a side sidewall of the combustion chamber, rear portion 2 of fire grate 3, also offer shoot door 9.

The utility model is simple in structure, moulded coal 10 is housed on the flat board 4 of fire grate 3 front portions in the combustion chamber 2 by fire door 5, moulded coal 10 is moved under the drive of its transmission device by coal-pushing plate 7, moulded coal 10 is pushed on the 2 middle part fire grates 3 of combustion chamber, this simple in structure being suitable for, it is easy to coaling, at any time the continuous moulded coal maintenance fired state of putting in stove, coal ash after the burning shoot door that 2 rear portions are offered from the combustion chamber goes out clearly, and deashing is convenient.

Accompanying drawing is the utility model structural representation.

Below in conjunction with description of drawings the utility model.

Referring to accompanying drawing, the utility model includes water jacket furnace, be opened in the combustion chamber in the body of heater bottom, fire grate constitutes, in body of heater 1, be provided with heat exchange heating tube 11 and heating cage plate 12, it is characterized in that, the bottom of body of heater 1 is cuboid combustion chamber 2, casting furnace grate 3 is established at middle part in combustion chamber 2, connect at the leading section of fire grate 3 and to be provided with one and to be used for the continuous flat board 4 of putting moulded coal 10, put moulded coal flat board 4 and on the nock face of combustion chamber 2 housings, offer fire door 5 continuing, continuous put on the moulded coal flat board 4 and 2 housing front end outsides, combustion chamber are provided with a push-type device for coal, it is arranged on a push pedal 7 of putting in the combustion chamber 2 on the coal flat board 4 by setting, with by push rod 71, fork 72, the link-type transmission device that support 73 constitutes constitutes, the right-hand member of push rod 71 and push pedal 4 welding are fixedly connected, the empty cover of its left end passes the antetheca 2 of combustion chamber 2 ' the place outside of combustion chamber of furnace body's 2 housings, the rear end of support 73 and combustion chamber of furnace body's 2 housing outer walls 2 ' be fixedly connected, the front end of the middle part of fork 72 and support 73 is hinged, the outer end of the lower end of fork 72 and push rod 71 is hinged, by moving the upper end of fork 72, drive push rod 71 and push pedal 7 are done and are moved forward and backward, moulded coal 10 is placed in by fire door 5 and puts on the coal flat board 4, push pedal 7 is at fork 72, move forward under push rod 71 promotes, the moulded coal 10 that promotes to be contained on dull and stereotyped 4 moves on the 2 middle part fire grates 3 of combustion chamber; The utility model offers shutter 8 as shown in the figure on a side sidewall of fire grate 3 lower combustion chamber 2, also offer shoot door 9 on a side sidewall of the combustion chamber, rear portion 2 of fire grate 3.

The transmission device of the utility model coal-pushing plate 7 also can be to be made of the crank connecting rod apparatus that is driven by motor, decelerator that setting is installed on 2 hull outside of combustion chamber.

The utility model is simple in structure, make easy, easy to operate, can in stove, continue easily at any time and put new coal, keep fired state, the moulded coal coal ash shoot door that 2 rear portions are offered from the combustion chamber after the burning can directly go out clearly easily, it had both brought into play the advantage of using moulded coal, overcome that the prior art structure is coaling and the shortcoming of deashing inconvenience simultaneously again.
