Description
Technical Field
The embodiment of the application relates to the technical field of hoisting, in particular to a hoisting assembly for hoisting a stirring mechanism, a stirring device and a hoisting method thereof.
Background
The radioactive waste liquid generated by the post-treatment of the spent fuel has the characteristics of high specific activity, high heat release rate, long half-life period of the contained nuclear element, complex chemical components and the like, and how to safely and effectively treat the radioactive waste liquid is one of important factors influencing the sustainable development of nuclear power. In recent years, the glass curing process has been used to treat radioactive liquid waste. The glass solidification process includes the steps of pre-treating radioactive waste liquid through calcination to convert the radioactive waste liquid into oxide (called as calcined product), mixing the oxide and glass base material in a smelting furnace according to a certain proportion, melting, casting, and annealing to fix radioactive nuclide in glass network to form stable glass solidified body.
The cold crucible glass solidification is carried out by generating high frequency (10) by power supply 5 ～10 6 Hz) current, and then the current is converted into electromagnetic current through the induction coil to penetrate into the material to be heated to form eddy current to generate heat, so that the material to be treated is heated and melted. The cold crucible is mainly composed of a high-frequency induction power supply, a cold crucible furnace body and other auxiliary devices, wherein the cold crucible furnace body is a container composed of metal arc blocks or tubes which are filled with cooling water, the cooling water is continuously filled into the metal tubes during working, the temperature of a fusant in the crucible can reach more than 2000 ℃, but the crucible still keeps lower temperature (generally less than 200 ℃) so that a layer of solid glass shell (cold wall) with the thickness of 2-3 cm is formed in a low-temperature region of the furnace body close to the tubes during the operation process, and the cold crucible is called as a cold crucible. The cold crucible does not need refractory materials and electrodes for heating, and because the molten glass is contained in the cold wall, the corrosion effect on the smelting furnace is reduced. The cold crucible glass solidification is suitable for treating high-, medium-and low-level radioactive waste liquid and organic waste liquid, and has the advantages of high melting temperature, wide waste treatment range, small volume, large treatment capacity, easy retirement, less retired waste, long service life of a furnace body and the like.
At present, mechanical stirring is widely applied to a cold crucible glass solidification process, for example, when radioactive waste liquid containing more noble metal ions is treated, a phenomenon of noble metal deposition at the bottom of a smelting furnace is easy to occur, so that a discharge pipe is blocked, an electrode in the smelting furnace is short-circuited, a stopping event occurs, and in order to avoid the similar events in the glass melting process, material deposition can be prevented through mechanical stirring. Above the cold crucible melting furnace, stirring devices/apparatuses are usually provided which, on the one hand, prevent the deposition of heavy metals and, on the other hand, increase the capacity of the glass for refractory metals by stirring the melt.
Due to the particularities of the cold crucible glass solidification process, the stirring mechanism/device is typically mounted obliquely above the cold crucible device. The cold crucible device works in a radioactive environment, and the stirring mechanism/device obliquely arranged above the cold crucible device needs to be disassembled by means of a mechanical arm or a power hand, so that the disassembling work and the hoisting work of the stirring mechanism/device have certain difficulty.

An application scenario of the hoisting assembly according to the embodiment of the application is described below with reference to fig. 1 to 3.
As shown in fig. 1, the lifting assembly 100 can be connected to a stirring mechanism 200 to cooperate with an external lifting device to lift the stirring mechanism 200. The stirring mechanism 200 is applied to a material preparation apparatus 300, and is used for stirring the material in the material preparation apparatus 300 during the operation of the material preparation apparatus 300, so as to optimize the material production. The material preparation apparatus 300 is, for example, a cold crucible apparatus. The stirring mechanism 200 has a mounting position to act on the material preparation device 300. The stirring mechanism 200 and the material preparation apparatus 300 may be mounted, for example, by flanges. When the stirring mechanism 200 is hoisted, it needs to be detached from the installation position and then hoisted.
In some embodiments, the material preparation apparatus 300 is, for example, a cold crucible apparatus. The stirring mechanism 200 may be installed in an inclined manner with respect to the cold crucible apparatus, that is, the stirring mechanism 200 is inserted into the cold crucible apparatus in an inclined manner at its installation position, and it is understood that the axis of the stirring mechanism 200 intersects with the horizontal plane. As shown in fig. 2, the stirring mechanism 200 is mounted in an inclined manner at a mounting position 1000, and the axis 210 of the stirring mechanism 200 forms an angle with the horizontal plane. The present disclosure may reduce operational complexity by implementing a vertical lift to the stirring mechanism 200. For example, during the process of lifting the stirring mechanism 200 from the position a to the position b along the arrow direction, the inclination angle of the stirring mechanism 200 is kept unchanged, i.e. the included angle formed by the axis 210 and the horizontal plane is unchanged. In addition, in the hoisting process, the stirring mechanism 200 can be prevented from shaking randomly and colliding with other devices or parts, and the residual materials on the stirring mechanism 200 can be prevented from splashing, so that the hoisting safety is ensured.
As shown in fig. 3, for example, the stirring mechanism 200 can enter and exit the material preparation apparatus through the opening 2000, and in order to move the stirring mechanism 200 out of the opening 2000, the present disclosure can hoist the stirring mechanism 200 from the position c to the position d along the arrow direction, so as to ensure that the inclination angle of the stirring mechanism 200 is unchanged, thereby further reducing the difficulty in hoisting.
The structure of the hoisting assembly according to an embodiment of the application is described below with reference to fig. 4.
As shown in fig. 4, the hoisting assembly comprises a support 10 and a connecting member 11, the support 10 is used for connecting with a stirring mechanism 200, and the connecting member 11 is arranged on the support 10 and used for matching with external hoisting equipment to realize hoisting.
Wherein, the support 10 plays a middle connection role and simultaneously supports the stirring mechanism 200 to a certain extent. The connecting member 11 has a smaller structure/volume than the support frame 10 and the stirring mechanism 200, is disposed on the support frame 10, and can indirectly bear the weight of the stirring mechanism 200 through the support frame, so as to cooperate with an external hoisting device to hoist and move the stirring mechanism 200.
Wherein, the connecting line between the position of the connecting piece 11 and the gravity center of the stirring mechanism 200 is perpendicular to the horizontal plane, or it can be understood that the center line of the connecting piece 11 along the vertical direction passes through the gravity center of the stirring mechanism 200, wherein, when the hoisting device is connected with the connecting piece, the connecting line of the hoisting device and the connecting piece along the vertical direction passes through the gravity center of the stirring mechanism 200. The vertical lifting of the stirring mechanism 200 can be achieved by the present disclosure.
In some embodiments, the stand 10 is rotatably coupled to the stirring mechanism 200. In this case, the stand 10 is convenient to have a variable state, for example, the stand 10 can be switched between an unfolded state and a folded state, and the stand 10 can reduce the occupied space when being folded, thereby avoiding affecting the use of the stirring mechanism 200.
In some embodiments, the rack 10 includes a first sub-rack 101 and a second sub-rack 102, one end of the first sub-rack 101 is connected to the stirring mechanism 200, the other end is connected to the second sub-rack 102, and one end of the second sub-rack 102 is connected to the stirring mechanism 200. Through setting up two sub-supports, the one end of two sub-supports can be connected with rabbling mechanism 200 respectively, and when the size that rabbling mechanism 200 extends along its axis direction was great, use two sub-supports for example to be connected to the both ends of rabbling mechanism 200 respectively, be favorable to improving the supporting role to rabbling mechanism 200, keep its focus stable to improve the stability of hoist and mount. As shown in fig. 4, the first sub-bracket 101, the second sub-bracket 102 and the stirring mechanism 200 are connected in sequence to form a triangular structure, so as to enhance the structural stability.
It will be appreciated that the number of sub-scaffolds is not limited to two, but may also be more than two, for example three, four or more. The connection relationship between the sub-brackets is not limited to the above manner, and can be adjusted according to actual conditions.
In some embodiments, one end of the first sub-mount 101 is hinged to the stirring mechanism 200, and the other end of the first sub-mount 101 is hinged to the second sub-mount 102. In other embodiments, one end of the second sub-frame 102 is also hinged to the stirring mechanism 200. The provision of the hinge enables the extension angle/direction of the first sub-mount 101 and/or the second sub-mount 102 to be changed relative to the stirring mechanism 200, for example, the shape of the triangle formed by the first sub-mount 101, the second sub-mount 102 and the stirring mechanism 200 is changed, which is beneficial for improving the space occupied by the mount 10.
It should be noted that the connection between the support 10 and the stirring mechanism 200 may be in other manners. For example, one end of each of the first sub-bracket 101 and the second sub-bracket 102 is slidably connected to the stirring mechanism 200, and in this case, for example, a sliding groove may be provided in the stirring mechanism 200, and one end of each of the first sub-bracket 101 and the second sub-bracket 102 may be inserted into the sliding groove and slid along the extending direction of the sliding groove. Further, a blocking portion may be disposed on the stirring mechanism 200 to limit the connection position of the first sub-bracket 101 and the second sub-bracket 102 on the stirring mechanism 200.
In some embodiments, the stent 10 further comprises: and a sliding part 103 provided on the second sub-mount 102, wherein the other end of the first sub-mount 101 can slide on the second sub-mount 102 through the sliding part 103. When the other end of the first sub-mount 101 slides on the second sub-mount 102, the support 10 is convenient to contract, and at this time, a partial structure of the first sub-mount 101 and a partial structure of the second sub-mount 102 may overlap, thereby reducing the occupied space of the support 10.
In some embodiments, the sliding portion 103 includes: and a sliding sub-part 1031 and a slide 1032, the other end of the first sub-bracket being hinged with the sliding sub-part 1031, so that the other end of the first sub-bracket can slide on the second sub-bracket along the slide 1032 by the sliding sub-part 1031. As shown in fig. 4, one end of the slideway 1032 is arranged at one end of the second sub-mount 102 close to the first sub-mount 101, and the other end of the slideway 1032 can be arranged at the middle of the second sub-mount 102 or at a position closer to the other end of the second sub-mount 102. The sliding sub-part 1031 can slide from one end to the other end of the slideway 1032 to bring the first sub-bracket to slide. The closer the first sub-mount 101 slides along the slide 1032 to the other end of the slide 1032, the smaller the contracted size of the mount 10 may be.
In some embodiments, stops (not shown) are provided at both ends of the runner 1032. The blocking piece can prevent the first sub-bracket 101 from sliding out of the second sub-bracket 102, or prevent the connection position of the first sub-bracket 101 and the second sub-bracket 102 from being separated to cause safety accidents in the hoisting process.
In some embodiments, the stent 10 has an expanded state and a collapsed state, and when the stent 10 is in the expanded state, the first sub-stent 101, the second sub-stent 102, and the stirring mechanism 200 form a triangle. As shown in fig. 4, the first sub-bracket 101, the second sub-bracket 102 and the stirring mechanism 200 form a right triangle, for example, which is beneficial to improving the stability of the stirring mechanism during the hoisting process and avoiding shaking.
In some embodiments, when the stent 10 is in the folded state, the space enclosed by the first sub-stent 101, the second sub-stent 102 and the stirring mechanism 200 is smaller than the space enclosed by the first sub-stent 101, the second sub-stent 102 and the stirring mechanism 200 when the stent is in the unfolded state. When the support 10 is in the folded state, the first sub-support 101 and the second sub-support 102 are closer to the stirring mechanism 200, and at this time, partial structures of the first sub-support 101 and the second sub-support 102 are overlapped, which is beneficial to reducing the occupied space, so as to avoid influencing the use of the stirring mechanism 200.
In some embodiments, the connector 11 is provided on the first sub-mount 101. As shown in fig. 4, when the stand 10 is in the unfolded state, the first sub-stand 101 extends, for example, in a horizontal direction, the second sub-stand 102 extends in a vertical direction, and a line connecting the position of the connecting member 11 and the center of gravity of the stirring mechanism 200 is perpendicular to the horizontal plane. Therefore, when the stirring mechanism 200 is hoisted through the connecting piece 11, the stability of the stirring mechanism 200 is ensured, and random shaking can be prevented.
The connecting piece 11 and the first sub-bracket 101 form a through opening, so that the lifting equipment can be conveniently connected with the connecting piece through the opening. The connecting member 11 is, for example, semicircular, and of course, the shape and structure of the connecting member 11 may be other forms, which the present disclosure does not limit.
Referring to fig. 2 to 4, when the stirring mechanism 200 is installed at an inclination, a line connecting the position of the connecting member 11 and the center of gravity of the stirring mechanism 200 can intersect with the axis 210 of the stirring mechanism 200. Through using the hoisting assembly of the embodiment of the application, the stirring mechanism 200 can be vertically hoisted, so that the hoisting difficulty is reduced, and the hoisting process is simplified.
Based on above-mentioned hoist and mount subassembly, this application embodiment still provides a agitating unit. A stirring device according to an embodiment of the present application is described below with reference to fig. 5 and 6.
As shown in fig. 5, the stirring device includes a lifting assembly 100 and a stirring mechanism 200. The hoist assembly 100 may be the hoist assembly of figure 4. The stirring mechanism 200 further comprises a stirring component 20 and a cover 21, wherein the stirring component 20 is used for stirring the material to be stirred, and the cover 21 covers the stirring component 20 and is used for protecting the stirring component 20.
The structure of the stirring device is described below with reference to fig. 6.
The stirring assembly 20 comprises a stirring rod part 201 and a blade 202, wherein one end of the stirring rod part 201 is connected with a driving device, and the other end of the stirring rod part 201 is connected with the blade 202. The stirring assembly 20 is used for extending into the material preparation device to stir the material. The driving device is used for providing power for the stirring assembly 20 so as to enable the stirring assembly 20 to work. The driving means is, for example, a motor, and in some embodiments, the motor may be disposed at one end of the stirring rod portion 201 and a position where the stirring rod portion 201 is connected to the paddle 202, so as to optimize power input. The stir bar portion 201 extends in the axial direction of the stir assembly 20 and has a longer axial dimension. The blades 202 have a larger radial dimension relative to the paddle portion 201. The blades 202 are, for example, of anchor construction, although other constructions are possible, such as impeller, frame, etc.
In some embodiments, the cover 21 includes a first sub-cover 211 and a second sub-cover 212, the first sub-cover 211 is configured to cover at least a portion of the stirring rod portion 201, and the second sub-cover 212 is configured to completely cover the blade 202. When the stirring assembly 20 is working, the stirring assembly 20 can be extended into the material preparation device, and when it is not working, the stirring assembly 20 can be retracted into the cover 21 to be protected by the cover 21. For example, in the process of preparing and hoisting, the blade 202 is completely covered by the second sub-cover body 212, so that the blade 202 can be prevented from colliding with other components.
In some embodiments, the bracket 10 is rotatably coupled to the first sub-housing 211. For example, a hinge may be provided at both ends of the first sub-housing 211 to be hinge-coupled to the stand 10, thereby moving the stand 10 between the unfolded state and the folded state. Fig. 6 shows the stand 10 in a folded state.
With reference to fig. 1-3 and 6, the stirring device is, for example, mounted at an angle to the material preparation device 300, both of which are connected, for example, by flanges. The axis of the stirring device forms an included angle with the horizontal plane.
