Description
Technical field
The utility model belongs to the chemical equipment field, has related in particular to a kind of catalyst and has added measure and control device.
Background technology
Catalyst is widely used in the Chemical Manufacture, and it can change the chemical reaction rate that can change other materials in chemical reaction of other materials, the quality that how much affects product of catalytic amount.Aborning, because the variation of material flow, the amount of adding catalyst also needs corresponding the adjusting.It generally is to measure first certain index of reactant to regulate afterwards the amount that catalyst adds by calculating in reactor that traditional catalyst adds observing and controlling.But because the delay on the life period will inevitably cause the product of a part not up to standard.The method is more loaded down with trivial details simultaneously, is not easy accurately to control the amount that catalyst adds.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can accurately control the device that catalyst adds.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
The measure and control device that a kind of catalyst adds comprises head tank, catalyst hooper and reactor, and its innovative point is: a flow counter device, be arranged between head tank and the former material conveying pump, and this flowermeter is used for measuring the raw material conveying capacity, and the output flow signal;
One weighing device is arranged on the catalyst hooper, and this device is converted to catalyst with the catalyst weight variable signal and adds rate signal, and the output speed signal;
One auger device is arranged on described catalyst hopper below, is used for carrying catalyst, and described screw conveyer device comprises frequency controller;
One master controller, this controller has signal input interface and signal output interface, and controller is by signal input interface and flow meter signal, and controller is communicated by letter with the auger frequency controller by signal output interface.
Further, an in addition control panel of described master controller communication, external signal is inputted master controller by control panel.
The utility model has the advantage of: catalyst adds measure and control device and has realized automation, need not manual operations, can observing and controlling with add comparatively accurate catalytic amount; There is not the problem of adding the catalyst delay in this equipment, and product has higher quality.
Description of drawings
Fig. 1 is the utility model device connection layout.
Fig. 2 is the utility model systematic schematic diagram.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage are clearer, further specify below in conjunction with accompanying drawing.The specific embodiment described herein only is not limited in the utility model in order to explain the utility model catalyst to add measure and control device.
In conjunction with Fig. 1, shown in Figure 2, the utility model comprises head tank 1, former material conveying pump 2, catalyst hopper 3, adds a flow counter device 5 between head tank 1 and former material conveying pump 2, and this flowermeter 5 can output flow signal F.The molality piece 6 that arranges on the catalyst hopper 3 can be converted to the catalyst weight variable quantity in the hopper catalyst and add rate signal V
1, the catalyst hopper below arranges screw conveyer device 7, carries catalyst by this device, possesses frequency controller on this auger simultaneously, thereby can change the interpolation speed that the auger frequency changes catalyst according to input signal.The utility model also comprises a master controller, and the signal input and output port is arranged, and signal input port is communicated by letter with weighing device 6 with flowermeter 5, changes the interpolation speed that the auger frequency changes catalyst thereby calculate output signal through the master controller program.
Workflow of the present utility model and principle are as follows:
Raw material is transported to from head tank 1 in the reactor 4 by pump 2, and flowermeter 5 produces flow F simultaneously, at this moment the interpolation speed V of catalyst
1Can be drawn by weighing device 6 signal F and V
1Input simultaneously in the master controller, in master controller, pre-enter rate value K, the interpolation catalyst velocity difference allowed band value V that consumes catalyst by control panel
s, time value T and relative program, master controller automatically to this moment required catalyst add speed V
2Calculate (V
2=K*F), and and V
1Contrast is as V=V
2-V
1〉=V
sAnd the duration, master controller sent the signal that changes frequency to screw conveyer device when reaching T, and screw conveyer device makes the interpolation speed of catalyst reach requirement in former reference frequency step gradual change ground increase frequency; In like manner, as V=V
2-V
1≤-V
sThe time and duration when reaching T, the gradual change of auger frequency steps reduces.
The utility model catalyst adds measure and control device and has realized automation, can parameter be arranged according to the actual requirement of different product, thereby adds an amount of catalyst.This device does not exist catalyst to add the problem that postpones simultaneously, so that product has higher quality.
