Description
Technical Field
The utility model relates to a feed arrangement field, concretely relates to device is added to acrylate emulsion auxiliary agent ration.
Background
The acrylate emulsion is formed by polymerizing monomers, a plurality of auxiliaries including a ph regulator, an initiator and the like are required to be added in the emulsion polymerization process, and the addition mode and the addition speed of the auxiliaries have great influence on the stability of a feed liquid, namely the polymer emulsion. The loss of the stability of local colloid in the emulsion polymerization process can cause the emulsion particles to coalesce to form condensate, and the generation of the condensate not only reduces the effective utilization rate of monomers and increases the downtime and the treatment cost of a polymerization device, but also increases the inconsistency of product performances among various kettles and batches and pollutes the environment. When the feeding device in the prior art is used for adding the auxiliary agent, the dispersing effect of the auxiliary agent added into the feed liquid is poor, so that the local concentration is too high, and the stability of the emulsion is influenced.

Drawings
FIG. 1 is a schematic view of the present invention;
in the figure: 1. the device comprises a reaction kettle, 10 parts of a vent pipe, 11 parts of a feed port, 12 parts of a breather valve, 20 parts of a metering tank, 21 parts of a pump, 22 parts of a flow regulating valve, 23 parts of a Venturi tube and 24 parts of a vent branch pipe.
Detailed Description
The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration purposes only and are not intended to limit the scope of the present invention.
As shown in fig. 1, the device for quantitatively adding the auxiliary agent into the acrylate emulsion of this embodiment is disposed on a reaction vessel 1.
In this embodiment, a vent pipe 10 connected to a gas source is disposed in the reaction kettle 1, and the vent pipe 10 is used for stirring the feed liquid in the reaction kettle 1. The breather pipe 10 is connected to the air supply, is equipped with the valve on the breather pipe 10. The reactor 1 is provided with a feed inlet 11 which can be opened and closed, the reactor 1 is also provided with a respirator, and the reactor 1 is communicated with the outside through the respirator. Gas enters the feed liquid through the vent tube 10, stirs and mixes the feed liquid, and finally escapes from the breather.
The utility model comprises a metering tank 20, a liquid outlet of the metering tank 20 is connected with a pump 21 and a flow control valve 22 in sequence, and the other end of the flow control valve 22 far away from the pump 21 is connected with a Venturi tube 23; the venturi tube 23 is arranged in the reaction kettle 1, and the axis of the venturi tube 23 coincides with the axis of the reaction kettle 1. Therefore, the outlet of the Venturi tube 23 is over against the center of the feed liquid, the auxiliary agent is sprayed into the feed liquid after being sprayed out of the Venturi tube 23, and the auxiliary agent and the feed liquid are rapidly and uniformly mixed by being matched with the stirring of the breather tube 10 for the feed liquid, so that the coagulation caused by the local loss of the stability of the feed liquid is avoided. Of course, besides the above-mentioned vent pipe, other forms of stirring devices may be used to mix the material liquid, for example, the lower end of the stirring shaft may be arranged at the bottom of the reaction kettle, and the stirring paddle may be arranged at the upper end of the stirring shaft, as long as the venturi tube 23 is not obstructed and is arranged right above the material liquid.
Preferably, the metering tank 20 is provided with a vent manifold 24 connected to a gas source. After the auxiliary agent dropwise add was accomplished, the utility model discloses in have remaining auxiliary agent, let in the 20 upsides of metering tank with gas through branch 24 of ventilating, blow in reation kettle 1 with remaining auxiliary agent in this device for the addition of auxiliary agent is more accurate, reduces the product difference between each batch.
Preferably, the utility model discloses still include control system. The flow control valve 22 is electrically connected to the control system, and further, the valves on the ventilation tube 10 and the ventilation manifold 24 are also electrically connected to the control system. The opening and closing degree of the flow regulating valve 22 can be controlled through a preset program in the control system, so that the dripping speed of the auxiliary agent is accurately controlled; the control system may also be programmed to control the opening and closing of the valves on the vent line 10 and the vent branch 24 according to the process requirements. Therefore, the automatic control of the operation process can be realized, and the error caused by manual operation is avoided.
