Description
Technical field
The present invention relates to the wet milk in CEMENTED CARBIDE PRODUCTION field, relate in particular to the wet milk with temperature automatic monitoring function.
Background technology
In CEMENTED CARBIDE PRODUCTION process, first need to utilize ball mill to carry out ball milling to manufacture compound to material (normally refractory carbide+Binder metal+additive).During ball milling, conventionally use organic liquid medium (being for example generally volatile alcohol), the wet milk so this ball mill is otherwise known as.
Fig. 1 is the schematic diagram of the wet milk of prior art.As shown in Figure 1, wet milk possesses cylindrical shell 101, cooling water inlet pipe road 102, cooling water outlet pipe road 103 and valve 104.Cylindrical shell 101 holds the material that need to carry out wet-milling.Cooling water inlet pipe road 102 is connected in cylindrical shell 101, when wet milk is worked, to cylindrical shell 101, for reply cylindrical shell 101, carries out cooling cooling water.Cooling water outlet pipe road 103 is also connected in cylindrical shell 101, when wet milk is worked, from cylindrical shell 101, discharges and cylindrical shell 101 has been carried out to cooling cooling water.Valve 104 is arranged at cooling water inlet pipe road 102.When valve 104 is opened, cooling water inlet pipe road 102 is to cylindrical shell 101 cooling water supplies.When valve 104 is closed, cooling water inlet pipe road 102 stops to cylindrical shell 101 cooling water supplies.
The wet-milling time is generally 24 hours to more than 100 hours.For the ultra-fine cemented carbide of current fast development, the wet-milling time is generally more than 96 hours.Wet-milling is seriously generated heat the material in cylindrical shell 101 for a long time, if cooling bad even cooling failure will cause the temperature in cylindrical shell 101 to raise.Now, the lighter causes the oxidation of compound to exceed standard, and the volatilization of severe one aggravation solvent causes the pressure in cylindrical shell 101 to raise, and likely causes Lou material or blast (this is serious dangerous accident).Therefore, only have the temperature of monitoring in real time in cylindrical shell 101, make it all the time in technique allowable temperature, the quality of guarantee compound, and avoid dangerous accident.
At present, in order to know the temperature in the cylindrical shell 101 of wet milk, normally rule of thumb from the temperature in the temperature estimation cylindrical shell 101 of the outer wall of cylindrical shell 101.
When wet milk is worked, the state of cylindrical shell 101 in continuous rotation, thereby cannot adopt contact continuous temperature-measuring method to measure continuously the temperature of the outer wall of cylindrical shell 101.Current general employing shut down discontinuous thermometry: first make wet milk quit work, re-use the temperature that hand-held infrared thermometer is measured the outer wall of cylindrical shell 101, or even with the outer wall of hand touch cylindrical shell 101, estimate temperature.Obviously, shut down the temperature that thermometry can not be measured the outer wall of cylindrical shell 101 continuously, only can obtain discrete temperature data.
In addition, owing to cannot regulating in real time the flow of cooling water according to discrete temperature data, thereby valve 104 can only adopt the electromotive intake valve that only possesses standard-sized sheet and two positions of complete shut-down.
The shortcoming of shutting down discontinuous thermometry is:
(1) state of temperature of the cylindrical shell of continuous monitoring wet milk in real time, causes monitoring blind area in time, especially when accident causes cooling bad even cooling failure, can not find in time, exists hidden danger;
(2) according to discrete temperature data, cannot realize the automatic control of temperature of the cylindrical shell of wet milk, cannot realize overtemperature alarm function and stopping function;
(3) can not automatically regulate for cooling cooling water, cause supply burden and the wasting of resources;
(4) can not automatically record the temperature of the cylindrical shell of wet milk, the reviewing of working condition that is not easy to wet milk checks analysis.
(5) shut down thermometric and increased the weight of operating personnel's labour intensity, affected production efficiency.
