Abstract
This utility model provides a kind of frequency conversion Calx batcher blocking rotation device, including DCS controller, the input of DCS controller connects flow transmitter, the outfan of DCS controller is connected with the converter controlling motor rotation speed in turn, motor and batcher, DCS controller gathers batcher output moment of torsion by torque sensor, this utility model is by increasing torque sensor in frequency conversion Calx batcher, running status by moment of torsion reflection batcher, find the stall situation of frequency conversion Calx batcher in time, the running frequency of Calx batcher is improved timely when there is stall, solve stall problem, the operation stability of increase system and safety.
Description
Technical field
This utility model belongs to powdery frequency conversion batcher and controls technical field, is specifically related to a kind of frequency conversion Calx batcher and prevents
Locked-rotor device.
Background technology
Frequency conversion Calx batcher rotational frequency needs to be adjusted according to the change of flow of inlet water, under low frequency state, and warp
Often causing stall, not blanking because of the reason of Calx caking and foreign body, after there is this situation, operations staff can only be from sight on the spot
Examine form to find, not only increase the workload of operation maintenance personnel, and failing to find frequency conversion Calx feed in time
The stall situation of machine will cause batcher to cause heating damage because of long-time stall, and occurs that the situation that effluent quality deteriorates is sent out
Raw.
Summary of the invention
In order to overcome problems of the prior art, this utility model provides a kind of frequency conversion Calx batcher blocking rotation
Device, increases torque sensor in frequency conversion Calx batcher, by the running status of moment of torsion reflection batcher, finds in time to become
Frequently the stall situation of Calx batcher, improves the running frequency of Calx batcher timely when there is stall, solves stall and asks
Topic, increases operation stability and the safety of system.
To achieve these goals, the technical solution adopted in the utility model is, frequency conversion Calx batcher blocking rotation device,
Including DCS controller, the input of DCS controller connects has flow transmitter, the outfan of DCS controller to be connected with control in turn
The converter of motor rotation speed processed, motor and batcher, DCS controller gathers batcher output by torque sensor and turns round
Square.
Described DCS controller is also associated with the DCS display of the data for showing DCS controller.
Described DCS display connects monitoring and alarming system.
Under normal operation, the process water yield of lime water processing system is transferred to DCS controller by flow transmitter,
Through calculating the frequency determining Calx batcher, when DCS watch-dog monitors batcher output moment of torsion beyond setting value (＞
Situation 16Nm), then output control signal controls the frequency rising of batcher converter, and time delay Preset Time (30S) judges afterwards,
If torque feedback is recovered normal (＜ 16Nm), then DCS watch-dog output control signal controls batcher converter frequency reducing, recovers
To running frequency before, if torque feedback continues to transfinite, then control monitoring and alarming system by DCS watch-dog and send feed
Machine stall is reported to the police, and batcher of stopping transport prevents batcher from damaging.
Compared with prior art, this utility model at least has the advantages that, this utility model is by passing moment of torsion
Sensor introduces in the middle of frequency conversion Calx batcher system, reflects the ruuning situation of Calx batcher with the size of torque value, in time
The situation of the stall not blanking that discovery frequency conversion Calx batcher causes because of reasons such as Calx caking, foreign bodies at running, reduces
Because Calx is not normally added the generation of the lime treatment system water quality deterioration situation caused, substantially increase system run all right
Property, reduce the fault rate of frequency conversion Calx batcher, and the dynamics of patrolling and examining reducing operations staff of high degree, thus save
Substantial amounts of manpower.
Further, this utility model has DCS display by connecting at the outfan of DCS controller, it is achieved that a distant place
The function of the running status of monitoring frequency conversion Calx batcher.
Further, DCS display connects and has monitoring and alarming system, after promoting batcher frequency converter frequency still
When can not solve the problem of stall, monitoring and alarming system sends alarm signal and reminds in time and carry out fault row in row attendant
Remove.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is workflow schematic diagram of the present utility model.
Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with the accompanying drawings.
Seeing Fig. 1, this utility model includes data acquisition and the program control that DCS controller, DCS controller are whole system
Center processed, be responsible for data acquisition, analyze, calculate and device status monitoring, Calx batcher frequency converter frequency control；DCS is controlled
The input of device processed connects the flow transmitter gathering pipeline instantaneous delivery, and the outfan of DCS controller is connected with control in turn
The converter of motor rotation speed processed, motor and batcher, DCS controller gathers batcher output by torque sensor and turns round
Square, described DCS controller is also associated with the DCS display of the data for showing DCS controller, and described DCS display connects
There is monitoring and alarming system.
Under normal operation, the process water yield of lime water processing system is transferred to DCS controller by flow transmitter,
Through calculating the frequency determining Calx batcher,
See Fig. 2, when DCS watch-dog monitors the batcher output moment of torsion situation beyond setting value (＞ 16Nm), the most defeated
Going out control signal and control the frequency rising of batcher converter, time delay Preset Time (30S) judges afterwards, if torque feedback is recovered
Normally (＜ 16Nm), then DCS watch-dog output control signal controls batcher converter frequency reducing, the operation frequency before returning to
Rate, if torque feedback continues to transfinite, then controls monitoring and alarming system by DCS watch-dog and sends the warning of batcher stall, and
Stoppage in transit batcher prevents batcher from damaging.
