The utility model is composed of a host machine and an electric control box two parts, wherein, a measuring chamber is arranged in the host machine which uses a photoelectric control mode to conduct the limit measurement, and the host machine is provided with a full dust sensor, a leakage sensor, a dust discharging and an air locking devices and transmission mechanisms, such as a tractive magnet, a linkage rod, etc. The electric control box is provided with an electromagnetic counter, an electronic time accumulator, a time relay, a sound and light alarm, a random detecting and measuring action and fault displaying mechanisms, etc. The utility model has accurate measurement, convenient operation, safety and low cost, being an ideal device for managing environmental protection.
Description
The utility model relates to a kind of coal-burning boiler dry-type dedusting equipment meter that gathers dust, and is a kind of meter of collecting dust on industrial production coal-burning boiler, the life coal-burning boiler dry-type dedusting equipment that is widely used in.
The requirement of overall control is proposed atmosphere pollution is carried out according to State Bureau of Environmental Protection, Shanghai City Environmental Protection Agency formulates and has issued DB31/76-92 " coal-burning boiler dry-type dedusting equipment operational management regulation " by Shanghai Bureau of Technical Supervision, wherein stipulate from July one, 1 all dry-type dedusting equipments must be equipped with dedusting and receive grey metering device.The meter of existing three kinds of metering aspects of gathering dust on the market, Shanghai.Their measuring principle has plenty of the projection electronic weighing of employing method; Have plenty of the automatic ash discharge of the electronic auger type conveyer of employing, press auger rotating cycle conversion electron signal, the method for after integrated package is handled, measuring.These methods produce metering and are forbidden after reality is used, and functional failure is on the high side, damages problems such as maintenance difficult easily.
The purpose of this utility model provides a kind of volume, the photo-electric control formula meter that gathers dust, and adopts the volume metering of gathering dust, and the mode of the photo-electric control accuracy of measuring reaches the purpose of gathering dust and measuring.And have other four kinds of functions concurrently.
The purpose of this utility model is achieved in that forming one by a columnar meter main frame and an electric appliance control box overlaps the meter that gathers dust.The top of main frame has entering-dust mouth to be connected with the dust mouth of deduster with flange, the main frame internal upper part is put cylindrical shape measuring room (limiting the quantity of for 1 kilogram), the measuring room top is a cone, if the dust passway of capacity, and photoelectric controller, when the control point is arrived in the dust spill-over, photoelectric controller promptly sends signal, tractive magnet is opened the dodge gate of tubular measuring room bottom, one kilogram of dust drops to the dust-storage chamber of meter automatically, and by time relay control time-delay closing dodge gate, the measuring room dust discharge finishes, dodge gate is closed automatically, and metering restarts to gather dust.Repeat said process, whenever carry out once, message register adds up once, the accuracy of measuring ± 2%.Reach the purpose of accurate metering.The utility model has also been installed for a long time device of electronics, and the meter power supply is connected with the deduster fan power, and synchronous operation can be carried out simultaneously the cleaner meter accumulative total running time timing of gathering dust.Gather dust metering, the operation timing cumulative data, all can keep for a long time during power failure.The utility model electrical equipment control part all adopts the generic stereotype product.Accurate measurement, multiple functional, safe and reliable, stable performance, easy to operate, durable in use, easy to maintenance.
The utility model embodiment is described further in conjunction with the accompanying drawings:
Fig. 1 is the meter main machine structure schematic diagram that originally gathers dust;
Fig. 2 is the meter electric appliance control box front schematic view of originally gathering dust.
By establishing cylindrical shape measuring room 1 in the meter main frame that gathers dust shown in Figure 1.Circular fat top dodge gate 2 is established in the measuring room bottom, for making accurate measurement, measuring room top dwindles bore with divergent-cone wall, stay a diameter top entering-dust mouth 14 to connect, establish photoemission cell 3 at straight neck place, optoelectronic receiver 4, for preventing that a large amount of dust from pouring photo-electric control and being quick on the draw a little, on photo-electric control, deploy bumper bar 17, when the photo-electric control hole was arrived in the dust spill-over, photoelectric controller sent signal, and tractive magnet 6 drives kinematic link structures 8, open the dodge gate 2 of measuring room bottom, 1 kilogram of dust in the measuring room drops to the dust-storage chamber of meter cylindrical shell 7 bottoms.The pulse signal that electromagnet startup is simultaneously sent is passed to message register 19, counts.There are connecting rod, movable axis to be connected above the full dirt arc driver plate 9, form full dust sensor with full dirt switch 5 with the top cover axle bed.Leak sensor 15 is formed leak sensor with leakage switch 16, can report to the police automatically when meter and deduster leakage.Put dirt door handle 10, put dirt door hold-down mechanism 11, rubber mat plate 12 is put dirt door 13, puts dirt mouth 18 composition meters and puts dirt, lock gas system.
Shown in the positive right figure of Fig. 2 meter electric appliance control box, electrical equipment control is established message register 19, electronics is device 20 for a long time, full dirt alarm buzzer 21, leakage alarm buzzer 22, tape light power switch 24, with machine testing, meter action indication, fault the Show Button indicator lamp 25, power supply indicator 26, full dirt alarm lamp 27, leakage alarm indicator lamp 28, electric appliance control box front Figure 29, and transformer, relay etc. are formed electrical equipment control metering of the present utility model, timing, warning, detection system in the control cabinet.Electric appliance control box is connected with main frame with cable.
The utility model is rational in infrastructure; easy for installation; electric parts all adopts the generic stereotype product; easy to maintenance; main frame and deduster are connected as a single entity, and further improve the air locking energy, and electric appliance control box and main frame are split type; connect with cable; be installed in by the boiler electric appliance control box, easy to operate, accurate measurement; safe and reliable; cheap, be convenient to promote, be suitable for various coal-burning boiler dry-type dedusting equipments and use; be a kind of desirable metering device that gathers dust, help environmental administration's administrative protection environment that exercises supervision.The utility model has broad application prospects.
Claims (3)
1, meter gathers dust, it is characterized in that adopting volume, the mode of photo-electric control is carried out the metering method of one kilogram of system, cylindrical shape measuring room 1, measuring room top is that divergent-cone wall dwindles volume, improve the accuracy of measuring, stay always that neck is connected with top entering-dust mouth 14, dispose photoemission cell 3, optoelectronic receiver 4 at straight neck, carry out photo-electric control, deploy buffering shelves bar 17 on photoelectric controller, when the control point was arrived in the dust spill-over, photoelectric controller sent signal, tractive magnet 6 drives kinematic link structure 8, open the circular fat top dodge gate 2 of measuring room bottom, message register 19 is carried out tally function simultaneously, and for a long time function of full dirt warning and electronics is arranged.
