Jacket type heat absorption assembly

Technical Field

The utility model relates to a waste heat recovery utilizes technical field, concretely relates to double-layered shell type heat absorption subassembly.

Background

The waste heat refers to heat energy which is generated by various heat energy conversion devices, energy utilization devices, chemical reaction devices and produced high-temperature workpieces and is not utilized in the production process. A large amount of waste heat which needs to be recycled exists in the industrial fields of textile printing and dyeing, electroplating processing, chemical pharmacy, printing and drying, coal slime drying, casting, electrolytic aluminum production and the like. If the energy can be fully utilized by recycling, the industrial energy loss can be greatly reduced. Meanwhile, waste heat recycling is an important way for improving the economy and saving the fuel.

Based on the above problem, I have researched and developed waste heat recovery circulation system, this circulation system is including the heat absorption subassembly, circulating pump, liquid reserve tank and the heat exchanger (or the stirling generator) that communicate in proper order, and wherein the heat absorption subassembly is used for placing the work piece of treating the cooling, can carry out cooling treatment to the work piece of high temperature through heat exchange medium in this circulation system in addition, with the heat circulation of high temperature work piece to heat exchanger (or stirling generator), realizes the recycle of waste heat.

Current heat exchange is generally through the heat exchanger, and the heat exchanger can only be applicable to the heat transfer of liquid such as water, but is comparatively difficult to the heat transfer of industrial high temperature work piece, and for example the heat exchanger is difficult to carry out the heat exchange to the electrolytic aluminum stub, because the heat exchanger is difficult to place or wrap up the electrolytic aluminum stub, can only place the electrolytic aluminum stub in one side of heat exchanger, but so heat exchange efficiency is extremely low, and the heat of scattering and disappearing is more.

SUMMERY OF THE UTILITY MODEL

The utility model provides a jacket formula heat absorption subassembly to carry out the heat exchange to the waste heat of high temperature work piece.

In order to achieve the above object, the utility model provides a following technical scheme: a jacket type heat absorption assembly comprises an outer barrel and an inner barrel arranged in the outer barrel, a channel for heat supply exchange medium to flow is arranged between the outer barrel and the inner barrel, an inlet and an outlet are arranged on the side wall of the outer barrel and are respectively communicated with the channel, supporting pieces communicated with the channel are arranged at the bottom of the inner barrel, and the supporting pieces are distributed in an array manner.

The utility model discloses a principle and beneficial effect:

compared with the heat exchanger used in the existing industry, the heat absorption component has the advantages that the heat exchanger can only be used for heat exchange of liquid or gaseous high-temperature substances, heat exchange of high-temperature workpieces is difficult to carry out, the heat exchanger is difficult to wrap the high-temperature workpieces, the high-temperature workpieces can dissipate a large amount of heat, and the heat exchange efficiency is extremely low. The heat absorption subassembly can be placed the high temperature work piece and wrap up in the inner tube in this scheme, so not only reduced the waste heat of high temperature work piece and lost, liquid metal can also flow through the passageway and carry out the heat exchange with the high temperature work piece, and the efficiency of heat exchange is high, and radiating heat is few.

The supporting piece can recover the waste heat at the bottom of the high-temperature workpiece, and the heat loss is reduced.

Further, a gap is reserved between every two adjacent supporting pieces, and a rack is arranged at the bottom of the outer barrel. The supporting tube can support high-temperature workpieces such as electrolytic aluminum stub and the like. When the high temperature work piece was placed on the stay tube, certain collision took place for difficult electrolytic aluminum anode scrap and stay tube, and electrolytic aluminum anode scrap receives the effort and can drop some residues, and in order to avoid the residue to stay in the inner tube, the residue can drop away through the clearance.

Furthermore, a material receiving plate positioned below the supporting piece is horizontally and slidably connected to the rack. The residue that drops can drop to connect the flitch through the clearance on, collect the residue through connecing the flitch.

Furthermore, a handheld piece for heat insulation is connected to the material receiving plate. Connect the flitch also can receive certain heat, when connecing the flitch to take out, operating personnel is hurt easily to high temperature, consequently insulates against heat through handheld piece butt joint flitch, avoids causing the damage to operating personnel.

Furthermore, a plurality of connecting pieces are arranged in the channel, and the outer cylinder is fixedly connected with the inner cylinder through the connecting pieces. The connecting piece is connected with the inner cylinder and the outer cylinder, so that the inner cylinder can be supported by the connecting piece.

Further, heat exchange tubes communicated with the outlet and the inlet are arranged in the channel and are spirally distributed along the outer side wall of the inner cylinder. The heat exchange tubes of spiral equipartition can prolong the time that heat exchange medium flows to make heat exchange medium can fully absorb heat, and the connecting piece can support inner tube and urceolus, if meet the extrusion that the inner tube received high temperature work piece, the connecting piece can support the inner tube, reduces the probability that the inner tube takes place to deform.

Further, the channel is provided with a waste heat pipe communicated with the support piece. The inner barrel is supported through the residual heat pipe, the probability of deformation of the inner barrel is reduced, and meanwhile the heat exchange pipe transmits liquid metal.

Further, the residual heat pipes are vertically arranged and are uniformly distributed in an array. The residual heat pipes are uniformly distributed in an array, so that the contact area between the residual heat pipes and the inner cylinder is the largest, and the contact area between the residual heat pipes and the electrolytic aluminum anode scrap needing heat exchange is the largest.

Further, the supporting piece is a heat absorbing plate, and the heat absorbing plate is communicated with the channel. The heat absorption plate supports the electrolytic aluminum anode scrap and exchanges heat with waste heat at the bottom of the electrolytic aluminum anode scrap.

Further, a ceramic layer is arranged between every two adjacent connecting pieces. The ceramic layer is inserted into the gap between the connector and the connecting member, thereby blocking the gap.
