Description
Technical field
The utility model relates to a kind of water-level control apparatus of coal-fired steam boiler, is specifically related to a kind of steam boiler water level adjusting device.
Background technology
Steam boiler is the Industrial Boiler of producing high-temperature steam, in China, the most coal that adopts of steam boiler that a lot of factories are used is as fuel, the heat that coal burning produces makes the water in boiler be converted into steam, because water is constantly converted into steam, water level in boiler is reduced, need to carry out moisturizing to boiler.At present, boiler main will pass through water pump automatic water supplement, in the time that water level reaches the highest designated water level, water pump stops moisturizing, and in the time that water level is reduced to minimum designated water level, starting mode of pump carries out moisturizing, low when high will cause the water level in boiler like this time, water-level fluctuation in boiler is larger, and quality of steam is unstable, is difficult to meet industrial demand.Therefore, how many water evaporations in boiler just covers how many, makes the water level of boiler keep constant, can make steam boiler keep best duty.In recent years, also some automatic water-replenishing devices have been there are, generally to adopt float-type structure, utilize the opening and closing of the buoyancy control inlet valve of water to float, but this automatic water-replenishing device does not possess the function of flow automatic regulation, can not accurately control inflow number, also just can not real-time balanced boiler in evaporation of water amount and rate of water make-up.
Utility model content
For overcome existing coal-fired steam boiler automatic water-replenishing device can not real-time balanced boiler in the deficiency of evaporation of water amount and rate of water make-up, the utility model provides a kind of steam boiler water level adjusting device, this steam boiler water level adjusting device can automatic control boiler inflow, evaporation of water amount and rate of water make-up in can real-time balanced boiler, make coal-fired steam boiler remain on low water level work, water-level fluctuation is less, steam water content is little, quality of steam is good and stable, can meet industrial demand.
The technical solution of the utility model is: this steam boiler water level adjusting device, comprise housing, the bottom of housing is connected with boiler, and the water level in water level and boiler that it is inner is consistent, the top of housing and middle part are fixed with respectively the first supporter and the second supporter, on the first supporter and the second supporter, be hinged with respectively entablature and sill, between entablature and sill, be connected by pull bar, the below at sill two ends is hinged with float and counterweight cylinder by rod member, and the weight of float is greater than the weight of counterweight cylinder; The second supporter is provided with and exports the water inlet pipe and the filling pipe that are positioned at top, water inlet pipe and filling pipe are communicated with outside water tank and boiler respectively, the below, middle part of entablature is provided with fan-shaped traffic conditioner block, the upper port of the lower surface of described traffic conditioner block and water inlet pipe and filling pipe fits, traffic conditioner block is provided with entity portion and hollow part, and traffic conditioner block deflection can make water inlet pipe be communicated with filling pipe.
Described counterweight cylinder is the cylindrical body of uncovered and top, below with water hole, and float is made up of stainless steel casing and light filling thing.
The bottom of described housing is fixed with guide post, and counterweight cylinder and float all slide along guide post.
The utlity model has following beneficial effect: owing to taking technique scheme, poised state by float and counterweight cylinder changes, the aperture of flow automatic regulation regulating block on water inlet pipe, evaporation of water amount and rate of water make-up in real-time balanced boiler, make coal-fired steam boiler remain on low water level work, water-level fluctuation is less, and steam water content is little, quality of steam is good and stable, can meet industrial demand.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this steam boiler water level adjusting device comprises housing 1, the bottom of housing 1 is connected with boiler 2, and the water level in the water level that it is inner and boiler 2 is consistent, the top of housing 1 and middle part are fixed with respectively the first supporter 3 and the second supporter 4, on the first supporter 3 and the second supporter 4, be hinged with respectively entablature 5 and sill 6, between entablature 5 and sill 6, be connected by pull bar 7, the below at sill 6 two ends is hinged with float 9 and counterweight cylinder 10 by rod member 8, and the weight of float 9 is greater than the weight of counterweight cylinder 10; The second supporter 4 is provided with and exports the water inlet pipe 11 and the filling pipe 12 that are positioned at top, water inlet pipe 11 and filling pipe 12 are communicated with outside water tank and boiler 2 respectively, the below, middle part of entablature 5 is provided with fan-shaped traffic conditioner block 13, the upper port of the lower surface of described traffic conditioner block 13 and water inlet pipe 11 and filling pipe 12 fits, traffic conditioner block 13 is provided with entity portion 14 and hollow part 15, and traffic conditioner block 13 deflections can make water inlet pipe 11 be communicated with filling pipe 12.
Owing to taking technique scheme, when steam boiler is normally worked, make water level in boiler 2 remain on low water level state and carry out work, close the water pump of automatic water supplement, open the valve on water inlet pipe 11, in the time that the water level in boiler 2 rises, water level in housing 1 also rises thereupon, float 9 rises under buoyancy, balance between float 9 and counterweight cylinder 10 is destroyed, the sill 6 of float 9 one sides upward deflects, and then traffic conditioner block 13 is deflected in company with entablature 5, the aperture that water inlet pipe 11 is blocked in entity portion 14 on traffic conditioner block 13 reduces, rate of water make-up reduces, in the time that the quantity of steam of water in boiler is greater than rate of water make-up, the interior water level of housing 1 declines, traffic conditioner block 13 yawing moments are contrary, the aperture of traffic conditioner block 13 on water inlet pipe 11 increases, keep equating with rate of water make-up until reach the quantity of steam of water in boiler, float 9 and counterweight cylinder 10 remain static again, poised state by float 9 and counterweight cylinder 10 changes, the aperture of flow automatic regulation regulating block 13 on water inlet pipe 11, evaporation of water amount and rate of water make-up in real-time balanced boiler, make coal-fired steam boiler remain on low water level work, water-level fluctuation is less, steam water content is little, quality of steam is good and stable, can meet industrial demand.
Described counterweight cylinder 10 is the cylindrical body of uncovered and top, below with water hole 16, and float 9 is made up of stainless steel casing and light filling thing.Counterweight cylinder 10 is selected stainless steel material, and light filling thing can adopt solid wood, plastic or other material.Avoid counterweight cylinder 10 and float 9 to produce corrosion.The effect of counterweight cylinder 10 has two, and the one, the weight of balanced float 9, makes entablature 5 and sill 6 stress equalizations, and entablature 5 and sill 6 are steady in the time of deflection; The 2nd, play the effect of current stabilization, avoid the water generates fluctuation of housing 1, and cause the fluctuation up and down of float 9, if the fluctuation up and down of float 9 can directly affect the aperture of water inlet pipe 11, just can not reach the object of self-choke.
The bottom of described housing 1 is fixed with guide post 17, and counterweight cylinder 10 and float 9 all slide along guide post 17.Ensure that counterweight cylinder 10 and float 9 Shi Buhui that moves up and down produces and departs from and occur jam phenomenon in housing 1.
