Description
Technical field
The utility model relates to a kind of proportioner of manufacture of cement, and specifically a kind of fly ash is stablized blanking and metering system.
Background technology
Fly ash is the dust that coal-fired plant boiler waste gas dust-precipitator is collected, the aluminum raw material and the composite material that can be used as manufacture of cement are used, generally, fly ash is to deliver in fly ash storehouse or less fine coal ash silo by pneumatic transporting, discharging under fine coal ash silo, is conveyed into production procedure after measuring.Due to the lighter 0.7m3/t of the unit weight left and right of fly ash, fineness is thinner, and flowing power is better.Punching material usually occurs in the discharging of fly ash, metering process, and the phenomenons such as scaffold, cause metering outfit metering inaccurate, and equipment emits ash serious, and contaminated environment increases workman's labor content, has a strong impact on the quality safety of cement products.The fly ash blanking that at present cement mill is used and gauging device exist and more serious rush material, emit ash, blanking is suddenly big or suddenly small and measures inaccurate problem.
Utility model content
The purpose of this utility model is exactly to solve an above-mentioned difficult problem, provides a kind of fly ash to stablize blanking and metering system, has solved the situation of said apparatus feed shakiness in fly ash blanking process.
The purpose of this utility model is to realize by following structure, it comprises: feed bin, and feed bin bottom is connected with spiral gate valve, and revolving plow reclaimer is established in feed bin below, the discharging opening place of revolving plow reclaimer establishes constant-current stabilizer, the below design flow belt feeder of constant-current stabilizer, described constant-current stabilizer comprises: shell is current stabilization chamber in shell, current stabilization is provided with dash plate in chamber, on shell, connect spiral gate valve, connect sealing hopper on measuring belt conveyer, sealing hopper connects spiral gate valve.
On described feed bin, be also connected with gas filled device, gas filled device comprises: more than 1 air slot of installing on feed bulkhead, and air slot is communicated with air dispenser, and air dispenser connects roots blower.
Described revolving plow reclaimer comprises: housing, in housing, establish stirring vane and impeller, and stirring vane is connected drive motor with impeller, and drive motor is frequency control motor.
On described constant-current stabilizer, be also provided with LOAD CELLS, the input end of LOAD CELLS connection traffic adjustment control, the mouth of flow regulating controller connects revolving plow reclaimer drive motor.
Described shell upper is provided with breather port.
Described measuring belt conveyer is provided with weight sensor, and weight sensor connects delivery controller.
The utility model, by adopting constant-current stabilizer, has overcome the phenomenon that original fly ash blanking device usually rushes material and easy scaffold, has guaranteed stability and precision that fly ash metering is added.Can also according to the fly ash amount in constant-current stabilizer, control the feed quantity of revolving plow reclaimer, further guarantee the stability of feed.Simultaneously of the present utility model simple in structure, cost is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model comprises as shown in Figure 1: feed bin, feed bin bottom is connected with spiral gate valve, revolving plow reclaimer 3 is established in feed bin below, and the discharging opening place of revolving plow reclaimer 3 establishes constant-current stabilizer 4, the below design flow belt feeder 5 of constant-current stabilizer 4, described constant-current stabilizer comprises: shell, in shell, be current stabilization chamber, current stabilization is provided with dash plate in chamber, connects spiral gate valve 2 on shell, on measuring belt conveyer 5, connect sealing hopper, sealing hopper connects spiral gate valve 2.On described feed bin, be also connected with gas filled device 1, gas filled device 1 comprises: more than 1 air slot of installing on feed bulkhead, and air slot is communicated with air dispenser, and air dispenser connects roots blower.Described revolving plow reclaimer comprises: housing, in housing, establish stirring vane and impeller, and stirring vane is connected drive motor with impeller, and drive motor is frequency control motor.Described bottom, current stabilization chamber is provided with 4 LOAD CELLS, the input end of LOAD CELLS connection traffic adjustment control 6, and the mouth of flow regulating controller 6 connects drive motor, and flow regulating controller 6 can adopt PLC controller.For eliminating the impact of air-flow, in the shell upper of constant-current stabilizer 4, be provided with breather port, breather port is taken over road to dust exhaustor, makes to remain in constant-current stabilizer 4 micro-negative pressure.Measuring belt conveyer 5 is provided with weight sensor, measuring belt conveyer 5 connects delivery controller, delivery controller can adopt PLC controller, delivery controller is adjusted belt speed automatically according to the metering signal of weight sensor, realize actual flow and predefined flow value is consistent, reach the object of stablizing blanking and automatic gauge batching.
The utility model is when operation, spiral gate valve is opened to maximum, fly ash in feed bin enters revolving plow reclaimer 3 after gas filled device 1 is loose, by revolving plow reclaimer 3 to constant-current stabilizer 4 feedings, LOAD CELLS detects the material weight in constant-current stabilizer in real time, after comparing by flow regulating controller 6 and setting value in advance, flow regulating controller 6 is controlled the rotating speed of the drive motor of revolving plow reclaimer 3, thereby the inventory realizing in feeding constant-current stabilizer 4 fluctuates in the scope requiring, in constant-current stabilizer 4, dash plate is installed, can prevents punching material.The spiral gate valve being connected between the sealing hopper of shell and measuring belt conveyer, for controlling the throughput of fly ash, makes the inventory that enters measuring belt scale 5 keep uniform and stable.
