Description

Plasticizer dissolver

Technical field

The utility model relates to carbide alloy technical field, relates in particular to the plasticizer dissolver for carbide alloy technology, and this plasticizer dissolver comprises for holding container and the agitator for plasticizer is stirred of plasticizer.

Background technology

In CEMENTED CARBIDE PRODUCTION, extruding is one of important molding mode.The compound being extruded must add plasticizer before extruding.Plasticizer is comprised of plasticising constituent element, active component and organic solvent conventionally, before using, three kinds of constituent elements is heated in advance and makes it mutual dissolving.

Heating means are in the past that three kinds of constituent elements are added in container and directly heat and stir with agitator with electric hot plate.

With electric hot plate, directly heat and have following shortcoming:

(1) in heating process, the miscible liquid of three kinds of constituent elements has certain viscosity, therefore container inner bottom part temperature is higher, upper temp is lower, and plasticizer dissolves inhomogeneous.While using this plasticizer solution, will while hot it be added to compound, this inhomogeneous plasticizer solution causes the plasticity of compound inhomogeneous, and the blank squeezing out easily produces longitudinal crack;

(2) organic solvent used is the flammable and combustible liquids volatile, flash-point is lower.Even electric heater unit be non-naked light and with temperature control and explosion-protection equipment, heat such material and also have larger hidden danger.

Therefore, the plasticizer dissolver as Types Below is sought in this area always, its should be able to: (1) makes plasticizer thermally equivalent in container, is uniformly dissolved, and guarantees the quality of plasticizer and extrusion blank; (2) when using the inflammable and explosive organic liquid volatile, flash-point is lower, guarantee production safety.

Utility model content

In order to solve existing technical problem, the utility model proposes a kind of plasticizer dissolver, this plasticizer dissolver comprises for holding container and the agitator for plasticizer is stirred of plasticizer, wherein, at the outer setting interlayer of container, Fluid Circulation heats with the plasticizer in container equably by interlayer.

Like this, the fluid circulating in the interlayer of external container can make the plasticizer in container be heated equably, and under agitator auxiliary, the dissolving of plasticizer is become evenly, thus the quality of assurance plasticizer and extrusion blank.In addition, the fluid that cycles through the interlayer of external container due to utilization heats the plasticizer of internal tank, therefore even also can guarantee production safety when using the inflammable and explosive organic liquid volatile, flash-point is lower.

Preferably, this fluid is water.

Preferably, this plasticizer dissolver has inlet valve and enters this interlayer for controlling this fluid, and has outlet valve and leave this interlayer for controlling this fluid.

Preferably, this plasticizer dissolver also has the Returning pipe between this outlet valve and this inlet valve.

Preferably, in this Returning pipe, heat channel is set, this fluid is heated in this heat channel.

Preferably, this plasticizer dissolver also has the electric heater being arranged in this heat channel.

Preferably, pump is also set in this Returning pipe, for this fluid that circulates.

Preferably, this fluid is heated to 90 ℃-93 ℃ by plasticizer.

Preferably, this container is rustless steel container.

Preferably, this plasticizer dissolver is the plasticizer dissolver for carbide alloy extrusion modling.

The specific embodiment

Fig. 1 is the schematic diagram of existing plasticizer dissolver 100.This plasticizer dissolver 100 has for holding container 102 and the agitator 104 for plasticizer is stirred of plasticizer.Being furnished with electric heater 106 for holding below the container 102 of plasticizer, for plasticizer being heated to desired temperature.Yet because plasticizer has certain viscosity, therefore container 102 inner bottom part temperature are higher, upper temp is lower, plasticizer dissolves inhomogeneous.When this inhomogeneous plasticizer solution is added in compound, will cause the plasticity of compound inhomogeneous, thereby make the blank squeezing out easily produce longitudinal crack.

In addition, the organic solvent as one of constituent element of plasticizer is the flammable and combustible liquids volatile, flash-point is lower.Owing to holding the wall of the container 102 of plasticizer, directly contact with electric heater 106, therefore even electric heater 106 be non-naked light and with temperature control and explosion-protection equipment, heat this organic solvent and also have larger hidden danger.

Fig. 2 is according to the schematic diagram of the plasticizer dissolver 200 of embodiment of the present utility model.This plasticizer dissolver 200 is with respect to the main distinction of the existing plasticizer dissolver 100 shown in Fig. 1, for holding the container 202 outer setting interlayers 206 of plasticizer, Fluid Circulation heats with the plasticizer in container 202 equably by interlayer 206.This fluid can be any fluid that is suitable for heating object, is preferably water.

This plasticizer dissolver 200 has inlet valve 208 and enters interlayer 206 for controlling fluid, and has outlet valve 210 and leave interlayer 206 for controlling fluid.Returning pipe 212 is arranged between outlet valve 210 and inlet valve 208, for the fluid that leaves container 202 is back to container 202 again.On Returning pipe 212, be provided with heat channel 214, electric heater 216 is arranged in heat channel 214, for heating being preferably the fluid of water in container 202 outsides.Meanwhile, on Returning pipe 212, be also provided with circulating pump 218, for making Fluid Circulation, flow.

Fluid is for being heated to desired temperature by plasticizer, and this temperature is preferably 90 ℃ to 93 ℃, more preferably 93 ℃.This container 202 is preferably double-layer stainless steel container.

Plasticizer dissolver 200 operations according to embodiment of the present utility model shown in Fig. 2 are as follows.Three kinds of constituent elements of plasticizer pack container 202 into, in container 202 inside, put into agitator 204, in the middle of the interlayer 206 of container 202, pass into circulating hot water.This hot water flows into this container 202 through heat channel 214 heating again after flowing out this container 202 again.So move in circles, the plasticizer in homogeneous heating container 202.

In the whole course of work, temperature, all the time lower than the flash-point of organic solvent in plasticizer, has prevented the potential safety hazard that may occur.

Therefore, in order to dissolve the plasticizer of carbide alloy pressing material, utilize the container 202 of the middle energy circulating hot water of interlayer 206, for realizing, hot water heating replaces electricity directly to heat, and can reach the object of homogeneous heating and safety in production.

With reference to the accompanying drawings of preferred embodiment of the present utility model, those skilled in the art do not depart from essence of the present utility model and spirit above, can have multiple flexible program to realize the utility model.These are only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence that all utilization the utility model descriptions and accompanying drawing content are done changes, within being all contained in interest field of the present utility model.
