Detailed Description
In order to make the objects, technical solutions and technical effects of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1 to 3, the present invention provides a high temperature liquid metal filtering apparatus, which includes:
the pipeline 20, the pipeline 20 has accommodating cavities 200;
the filter 1 is detachably and hermetically arranged in the accommodating cavity 200;
a discharge pipe 2 hermetically connected below the containing cavity 200, wherein a heating element for heating the discharge pipe 2 is arranged on the discharge pipe 2; and
and a recovery tank 7 hermetically connected below the discharge pipe 2 for receiving the liquid metal flowing out of the discharge pipe 2.
Referring to fig. 1, a receiving cavity 200 is formed at a suitable position of the pipe 20, and the filter 1 is hermetically installed and positioned in the receiving cavity 200 by the end cap 11. For example, the end cap 11 is detachably mounted to the pipe 20 by bolts to facilitate replacement and removal of the filter 1. The pipe 20 connected with the filter 1 has no acute angle, and the reachable area of the liquid metal is of a round/obtuse angle structure, so that the liquid metal is convenient to discharge and the local abrasion is reduced.
The filter element of the filter 1 is a metal net structure, and the mesh number of the filter screen can be selected according to the requirement. The metal framework support is arranged in the filter screen of the filter 1, so that the filter screen is prevented from being deformed and damaged due to high-density liquid metal scouring. The filter screen keeps a certain clearance with the pipeline 20 to ensure that the effective filtering area is as large as possible. According to an embodiment of the present invention, the filter 1 should form an angle with the center line of the pipe 20, for example, the angle between the center line of the filter 1 and the flowing direction of the liquid metal in the pipe 20 is an acute angle, and the specific angle is determined according to the specification and the size of the pipe 20, and it is required to ensure that the effective flow area of the filter 1 is not smaller than the sectional area of the pipe 20.
In the embodiment shown in fig. 1, the lowest point of the accommodating cavity 200 is hermetically connected with the discharge pipe 2 to ensure that the metal remaining in the accommodating cavity 200 flows out of the accommodating cavity 200 as much as possible when melted by heat, thereby facilitating the recycling of the metal. A differential pressure transmitter 13 is provided between the pipe 20 located upstream of the filter 1 and the pipe 20 located downstream of the filter 1, and after the filter 1 is put into use, the differential pressure transmitter 13 can monitor the pressure drop of the filter 1, and if the pressure drop of the filter 1 is too large, the filter 1 is taken out and cleaned or replaced.
Referring to fig. 2, the discharge pipe 2 is connected to the lowest point of the accommodating cavity 200, and mainly functions as: the recovery tank 7 is isolated during the service life of the filter 1, the recovery tank 7 being isolated from the surrounding atmosphere during the withdrawal of the liquid metal emptied into the recovery tank 7.
Referring to fig. 2 and 3 together, the heating element is an electric heating wire 5 disposed around the discharge pipe 2. In order to allow the liquid metal remaining at the bottom of the filter 1 to smoothly flow into the recovery tank 7, the discharge pipe 2, the valve 3, and the recovery tank 7 are heated to a temperature higher than the melting point of the liquid metal. In the process of putting the filter 1 into service, the electric heating wire 5 provides a heat source for the heated equipment and provides a relatively stable temperature boundary.
The discharge pipe 2 is provided with heat insulation cotton 6 coated with the electric heating wire 5, so that heat generated by the electric heating wire 5 is prevented from diffusing into the air, and the temperature of the coating part of the heat insulation cotton 6 is higher than the melting point of the liquid metal in the use process of the filter 1.
The discharge pipe 2 is provided with at least one valve 3, the valve 3 is in a closed state during the normal use of the filter 1, the main function is to isolate the recovery tank 7, and the valve 3 can be opened to empty the liquid metal in the filter 1 in the filter element replacement and maintenance processes of the filter 1. In the embodiment shown in fig. 1, a valve 3 is respectively arranged at one end of the discharge pipe 2 close to the filter 1 and one end of the discharge pipe close to the recovery tank 7, a quick coupling 4 is arranged on the discharge pipe 2, the quick connection between the valve 3 and the discharge pipe 2 can be realized through the quick coupling 4, and the recovery tank 7 can be conveniently taken out.
With continued reference to fig. 1, the recovery tank 7 is a sealed container that provides a pressure vessel for the discharged liquid metal to meet the requirement of liquid metal not diffusing outward under different internal and external pressure differences. The recycling tank 7 is stored with a recycling bin 10 facing the lower part of the discharge pipe 2 in a closed environment, the recycling bin 10 is made of S31608 and used for rapidly taking the liquid metal discharged from the filter 1 out of the recycling tank 7, the recycling bin 10 is a movable part, and a positioning clamp is arranged at the bottom of the recycling bin and fixed with a sealed container to prevent the recycling bin from moving in the using process.
The recovery tank 7 is provided with a tank body and a cover plate 12 which is hermetically arranged on the tank body, the cover plate 12 can be opened, and the interior of the tank body is connected with a vacuum pump 8 through a pipeline which penetrates through the cover plate 12 and a gas valve 9. The vacuum pump 8 is used for vacuumizing the recovery tank 7, controlling the oxygen concentration content in the recovery tank 7, and simultaneously improving the pressure difference between the pipeline 20 and the recovery tank 7, so that the residual liquid metal can be recovered conveniently.
The surface of the recovery tank 7 is also coated with heat insulation cotton 6 to prevent the heat generated by the electric heating wire 5 from diffusing into the air. The coating range of the heat-preservation cotton 6 is a high-temperature area of the whole filtering device, so that the temperature of the coating part of the heat-preservation cotton 6 is higher than the melting point of the liquid metal in the use process of the filter 1.
It should be noted that, according to actual needs, the discharge pipe 2 and the recovery tank 7 are respectively provided with a temperature measuring device (not shown) for measuring and monitoring the temperature of the liquid metal, and the electric heating wire 5, the pipeline 20 and related equipment are respectively provided with an electric heating element and a power control system.
The method of using the high temperature liquid metal filtering device of the present invention is described in detail with reference to fig. 1 to 3, wherein the default valve 3 and the gas valve 9 are both in a fully closed state unless otherwise specified.
Before the high-temperature liquid metal filtering device is put into use, the high-temperature liquid metal filtering device completes prepositive work such as equipment electrical and instrument control in the device, device air tightness inspection and the like, and has liquid metal circulation conditions. In the test process, the medium in the pipeline 20 can repeatedly pass through the liquid metal filter, so that impurities such as lead oxide in the medium can not enter the system equipment (between the mechanical pump sealing ring and the electric heating rod) to cause equipment damage.
After the liquid metal test is carried out for many times, because the generation of impurities in the medium is inevitable, the accumulated impurities of the filter 1 are more and more, and when the pressure difference of the medium before and after the filter 1 exceeds the test requirement value (the numerical value is determined according to the actual use condition), the filter 1 needs to be replaced.
Installation of the filter 1: for easy disassembly, filter 1 is flanged (not shown) onto pipe 20 in an orientation that is consistent with the flow direction of the liquid metal within filter 1, and differential pressure transmitter 13 is installed according to the particular model. After all the installations are completed, it is confirmed that the valve 3 is in a closed state.
Use of the filter 1: the filter 1 can be used after being heated to a temperature higher than the melting point of the liquid metal, the reading of the differential pressure transmitter 13 is monitored in the using process, and if the pressure drop is obviously higher than the initial state, the filter 1 needs to be replaced by taking the shutdown into consideration.
Replacement of the filter 1: before the operation starts, the whole system should complete the recovery of the liquid metal, and system impurities and part of the liquid metal will remain in the filter 1. The valve 3 is connected with the recovery tank 7 through the quick connector 4, the gas valve 9 is opened, and the recovery tank 7 is vacuumized through the vacuum pump 8. Driven by the pressure difference and gravity of the system and the recovery tank 7, the liquid metal and part of impurities flow into the recovery barrel 10 in the recovery tank 7, and the vacuum pump 8 can not continuously pump the vacuum, namely after the filter 1 is communicated with the recovery tank 7, the liquid metal and the impurities in the filter 1 are considered to be basically discharged into the recovery barrel 10.
The temperature is kept still for more than 1 hour, and the residual liquid metal and impurities are considered to be discharged after dropping into the recycling bin 10. After the filter 1 is completely discharged, the temperature of the filter 1 is reduced to a touchable temperature, then the quick connector 4 is disconnected, the end cover 11 is removed, and the filter 1 is replaced.
The recovered liquid metal is stored in the recovery barrel 7, the recovery cover plate 12 can be opened to take the recovery barrel 7 out, and the mixture of the liquid metal and impurities in the recovery barrel 7 can be reloaded into the liquid metal system again after being filtered. The opening and closing of the valve can be controlled in the whole operation process, so that the liquid metal is prevented from being directly exposed in the atmospheric environment, and the operation risk is reduced.
As can be seen from the above detailed description of the embodiments of the present invention, compared with the prior art, the high temperature liquid metal filtering apparatus of the present invention is provided with the discharge pipe 2 hermetically connected to the housing chamber and the recovery tank 7 hermetically connected to the discharge pipe 2, and the heating element provided on the discharge pipe 2 can heat and melt the metal remaining at the bottom of the housing chamber 200 and flow into the recovery tank 7 from the discharge pipe 2, so that the liquid metal can be ensured to be in a reducing environment, and the introduction of impurities due to oxidation of the liquid metal can be avoided. The filtering operation process is closed, the pollution of the liquid metal to the surrounding environment can be avoided, the direct contact of personnel and the liquid metal is avoided, and the safety risk is effectively controlled.
