Description
Technical field
A kind of material dropping device of synthesis polycarboxylate water-reducer reaction kettle of the utility model, belongs to the addition of reaction kettle material
Equipment technical field.
Background technology
It is well known that polycarboxylic acid series high efficiency water reducing agent has water-reducing rate high, good dispersion, volume is low, concrete contraction percentage
Low, molecular structure adjustability is strong, and high performance potentiality are big, production process without " three wastes " generate, it is environmentally protective outstanding advantages of,
It is widely applied, plays a significant role, it has also become 21 century high performance concrete admixture in the great key project of country
The hot spot of research and development, in recent years, the development that China's building cause is just being advanced by leaps and bounds, polycarboxylate water-reducer market demand play
Increase, there is wide development space.
The synthesis of polycarboxylate water-reducer, typically with isoamyl alcohol polyoxyethylene ether or isobutene alcohol polyoxy ether, propylene
Acid and its ester are primary raw material, under aqueous phase oxidation reduction initiating system, molecular weight regulator effect, by polymerisation
It obtains, in order to make reacting balance, uniformly carry out, it is excessively rapid fierce to prevent, and causes unnecessary accident generation or the life of byproduct
At especially polymerisation needs to use dropwise operation in many chemical reactions, and industrial production polymerization technique was added dropwise at present
Journey mostly uses the valve adjusted in high-order tank systems or adjusts wriggling pump frequency to control uninterrupted and time for adding.
The above dropwise addition mode has the following disadvantages：Head tank Dropping feeder is reduced with the liquid level of dropwise addition carried out in slot,
Pressure in slot is smaller and smaller, and dripping quantity at any time can be fewer and fewer, and valve is added dropwise if do not adjusted at any time, can lead to unit
Dripping quantity is different in time, that is, is added dropwise not at the uniform velocity, meanwhile, in the case where dropwise addition total amount is constant, time for adding can be extended, it is above
Situation can cause unstable product quality, and use peristaltic pump Dropping feeder, since voltage instability can cause to be added dropwise not at the uniform velocity, drop
Add fluctuation larger, has variation using the card wheel of its rotation is elastic for a long time, if infrequently demarcated, can cause in the unit interval
Wriggling dripping quantity is different, and dropwise addition is uneven, can cause unstable product quality.
Utility model content
The utility model overcomes the shortcomings of the prior art, provides one kind and accurately controlling material additive amount, realizes
It is accurate to be added dropwise, ensure the reaction kettle material dropping device of product quality.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of synthesis polycarboxylate water-reducer
The material dropping device of reaction kettle, including material accumulator tank and reaction kettle, material accumulator tank are provided with reaction kettle holder and are connected to
Pipeline is provided with control valve and flowmeter on the connecting pipe between material accumulator tank and reaction kettle.
The material savings pot bottom is higher than at the top of reaction kettle.
The material dropping device further includes controller, and the controller is connected with control valve and flowmeter.
Alarm interlock is provided on the flowmeter.
The utility model has the advantages that compared with prior art.
1, it is provided with control valve and flowmeter on the pipeline between material accumulator tank and reaction kettle, it can be accurately real
Accurate be added dropwise is realized in existing flow control.
2, alarm interlock is provided on flowmeter, can when flow occurs abnormal closing control valve,
Inlet pipe is cut off, alarm is carried out at the same time, staff is prompted to carry out inspection processing.
3, it is provided with controller, controller is connected with control valve and flowmeter, can be opened with remote control valve, remotely
Flow is monitored, the working strength of Field Force is reduced.
Description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
In figure 1 be reaction kettle, 2 be material accumulator tank, 3 in order to control device, 4 be alarm interlock, 5 be flowmeter, 6 be control
Valve processed, 7 be feed inlet, 8 be holder.
Specific implementation mode
As shown in Figure 1, a kind of material dropping device of synthesis polycarboxylate water-reducer reaction kettle of the utility model, including material
Accumulator tank 2 and reaction kettle 1, material accumulator tank 2 are provided with connecting pipe, material accumulator tank 2 and reaction kettle 1 with 1 holder of reaction kettle
Between connecting pipe on be provided with control valve 6 and flowmeter 5,2 bottom of material accumulator tank is higher than 1 top of reaction kettle, material
Dropping feeder further includes controller 3, and the controller 3 is connected with control valve 6 and flowmeter 5, and alarm is provided on flowmeter 5
Interlock 4.
When the utility model is used, material accumulator tank 2 is arranged above holder 8, ensure that the bottom of material accumulator tank 2 is high
In the top of reaction kettle 1, the unlatching by 3 operation and control valve 6 of controller and closure, flowmeter 5 can monitor dropwise addition in real time
Flow valve is linked by the alarm interlock 4 that is arranged on flowmeter 5 and is closed, report is simultaneously emitted by after flow is exceeded
Alert signal, prompts staff's timely processing.
The embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of various changes can be made.
