Abstract

The utility model relates to an energy saving adjustor of a boiler air channel. Air supplying quantities are controlled by gear positions. A plurality of corresponding convex bodies and grooves are formed at both sides of a chute of a sliding track (2) on which an operating rod (1) slides, and the convex bodies and the grooves are marked with air allocating quantities. After the operating rod (1) which is connected with an air adjusting plate (6) discontinues, the operating rod is connected with a sleeve barrel (4) in which a spring post (5) is arranged; one end of the operating rod (1) after discontinuing extends into the sleeve barrel (4), and acts with the spring post (5). Because the convex bodies and the grooves at the both sides of the chute of the sliding track are marked with the indication of the optimal air allocating quantities through calculation and experiments, workers have operability for saving energy. The workers do not like to move a previous air adjusting device once in one year, and air is only adjusted by pulling primary air more blindly at the front of the boiler; after the air adjustor is arranged, the workers can conveniently adjust the air under the guidance of scales. For example, the original coefficient of the excess of the air is totally between 1.0 to 1.6, the coefficient of the excess can be controlled between 1.15 to 1.20 because of the utility model, and the thermal efficiency of the boiler is enhanced by 2% to 3%.

Description

The energy-conservation adjuster in boiler air channel

(1) technical field:

The utility model belongs to the energy-conservation adjuster in boiler air channel.

(2) background technology:

Plate washer on 6-20 ton/hour boiler wind speed adjustment road is originally by nut lock operation bar at present, does not have the quantitatively beautiful device of indication of aperture again.Need when the workman operates to open nut, prevent carefully that again plate washer is dead by the wind band with spanner, sometimes because of vibration is arranged, nut loosening, quick-fried stove accident after death can be taken place by the wind band in the wind plate washer.

(3) utility model content:

Technical problem to be solved in the utility model is at the problem that exists in the background technology, controls the energy-conservation adjuster in boiler air channel to air quantity and provide a kind of with gear.

The invention for solving the technical problem can reach by following technical solution: the chute both sides that action bars slides on slide rail form several corresponding convex body, grooves that indicate the air distribution amount; Be connected with sleeve with having no progeny between action bars that air regulating board is connected, put spring stack in the sleeve, an end of an action bars of having no progeny stretches into sleeve and acts on mutually with spring stack.Change present gear-type locking into by original nut locking; The 2nd, by technical staff's contrast test,, on gear, mark calculating to air quantity for required corresponding of fuel quantity, reach the purpose that the workman operates reasonable wind distribution.

The utility model is compared with background technology has following beneficial effect: the workman transfers wind without spanner, need not be on tenterhooks, and stuck the preventing of lever become flexible: to indicate with the best air distribution amount of experiment because of indicating at the chute both sides of slide rail convex body, groove as calculated, make the workman on energy-conservation, operability arranged.Louver in the past, the workman was reluctant movingly once to transfer wind only by stokehold wind of pulling blindly in 1 year, this air register is installed now after, the workman is easily having scale to transfer wind under instructing., now can be controlled between 1.15～1.20 generally all between 1.0～1.6 as, former coefficient of excess of the wind comes from, boiler thermal output improves 2～3%.

(4) description of drawings:

Accompanying drawing 1 is the schematic diagram of this air channel adjuster;

Accompanying drawing 2 is schematic diagrams of conventional air channel adjuster.

(5) specific embodiment:

Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:

In conjunction with shown in Figure 2, contain the action bars 1 of air regulating board 6 and connection by Fig. 1 on the boiler air channel 8, action bars slides along slide rail 2.This adjuster is that the chute both sides that action bars 1 slides on slide rail 2 form several corresponding convex body, grooves that indicate the air distribution amount; 1 of the action bars that is connected with air regulating board 6 is had no progeny and is connected with sleeve 4, puts spring stack 5 in the sleeve, and an end of an action bars of having no progeny 1 stretches into sleeve 4 and acts on mutually with spring stack 5.

By shown in Figure 2, transferred air quantity with spanner loose nut 7 originally, pull the purpose that action bars 1 reaches air regulating board 6.By shown in Figure 1, slide rail 2 is to be contained on the support 3.Boiler is in heat supplying process, and air quantity is as required moved the handle of action bars in the corresponding recesses of slide rail both sides to and to be blocked.

Claims

A kind of energy-conservation adjuster in boiler air channel that relates to, the action bars (1) that contains air regulating board (6) on the boiler air channel (8) and connect, action bars slides along slide rail (2), it is characterized in that: the chute both sides of going up action bars (1) slip at slide rail (2) form several corresponding convex body, grooves that indicate the air distribution amount; Be connected with sleeve (4) with having no progeny between action bars (1) that air regulating board (6) is connected, put spring stack (5) in the sleeve, an end of an action bars of having no progeny (1) stretches into sleeve (4) and acts on mutually with spring stack (5).
