Description

Long-tube type heat absorption assembly

Technical Field

The utility model belongs to energy-conserving heat transfer field, concretely relates to long cylinder 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 high-temperature workpieces and is not utilized in the production process. A large amount of waste heat 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, and the waste heat is directly wasted. If the energy can be fully utilized by recovery, the industrial energy loss can be greatly reduced, and meanwhile, the waste heat recovery and utilization 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 that communicates in proper order, the circulating pump, the liquid reserve tank and heat exchanger (or stirling generator), wherein the heat absorption subassembly is used for placing high temperature work piece or other high temperature article, and heat exchange medium can adopt water, oil or the liquid metal of this department's research and development in this circulation system in addition, can carry out cooling treatment to the work piece of high temperature through heat exchange medium, with the heat circulation of high temperature work piece to heat exchanger (or stirling generator) department, realizes the recycle of waste heat.

Because the existing high-temperature workpieces have different shapes, such as long rod-shaped workpieces, short rod-shaped workpieces, cuboid-shaped workpieces and the like, heat absorption components which are matched with the workpieces in various shapes are not arranged in the prior art, and therefore, the heat absorption components are researched and designed aiming at the workpieces in different shapes.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a long cylinder heat absorption subassembly suitable for place long bar-shaped work piece and carry out the cooling.

In order to achieve the above purpose, the technical scheme of the utility model is that: the long-tube heat absorption assembly comprises a heat exchange tube, wherein a cooling channel for heat exchange medium circulation is arranged on the side wall of the heat exchange tube, and a liquid inlet hole and a liquid outlet hole which are communicated with the cooling channel are formed in the side wall of the heat exchange tube; a placing plate is connected in the heat exchange cylinder in a sliding mode, and a containing groove is formed in the placing plate.

The working principle and the beneficial effects of the technical scheme are as follows:

1. place the work piece and carry out the heat transfer in a heat exchanger section of thick bamboo, and cooling channel sets up at a heat exchanger section of thick bamboo lateral wall, and the lateral wall that is equivalent to a heat exchanger section of thick bamboo promptly is equipped with intermediate layer heat supply exchange medium and passes through, and in the cooling process, the heat of work piece outwards gives off and receives interbedded blockking for the better heat absorption of the intraformational liquid metal of intermediate layer improves heat exchange rate and waste heat recovery rate.

2. The placing plate is connected in the heat exchange cylinder in a sliding mode, on one hand, when a workpiece is placed, the long rod-shaped workpiece is long, the placing plate is arranged at the bottom of the heat exchange cylinder, and when the long workpiece extends into the heat exchange cylinder, the workpiece and the accommodating tank are difficult to align; on the other hand, when the casting shaping, can directly place the mould and cool off the shaping in this device, and molten metal when pouring in the mould, can hardly have the metal liquid that drips to the mould outer wall, when taking out the mould after the cooling, the adhesion is difficult to avoid dropping at the metal residue of mould outer wall, and the residue drops on placing the board, when taking out the work piece or placing the work piece, will place the in-process that the board slided to a heat exchanger section of thick bamboo tip, can take the residue out, conveniently clears up the residue.

Further, the heat exchange cylinder is vertically arranged.

Has the advantages that: since long rod-shaped workpieces are generally long and have small end surface areas and tend to fall down when standing upright, they are generally cooled by being stacked horizontally during cooling, and therefore have a large footprint.

Has the advantages that: compared with the driving by using an air cylinder or a hydraulic cylinder and the like, the output shaft of the air cylinder or the hydraulic cylinder has overlarge movement stroke, so that a larger air cylinder or hydraulic cylinder is needed, the occupied area is larger, and the cost is higher; use motor drive to place the board and slide in this scheme, reducible area.

Further, the lower end of the ball screw is provided with a smooth section, an annular groove is formed in the smooth section, a horizontal fixing rod is fixed to the lower portion of the heat exchange cylinder, and one end, far away from the heat exchange cylinder, of the fixing rod is inserted into the groove.

Has the advantages that: the fixed rod carries out spacing support to ball screw lower extreme, avoids ball screw too big moment of torsion to lead to crooked in the use.

Furthermore, the top of the heat exchange cylinder is detachably connected with a cover body.

Has the advantages that: set up the lid, avoid the heat of work piece to scatter and disappear from the heat transfer section of thick bamboo top, improve waste heat recovery rate.

Further, the position that lies in on the placing plate outside the holding tank is hollowed out and is set up, and a heat transfer section of thick bamboo lower extreme is fixed with receives the sediment case.

Has the advantages that: the work piece is after processing, and the surface of work piece is difficult to avoid remaining the residue that iron fillings or other impurity formed, and the work piece is placed refrigerated in-process for a long time or the work piece when putting into a heat transfer section of thick bamboo and the collision of heat transfer section of thick bamboo inner wall, and the residue can drop downwards to place the board through the fretwork setting and drop to the receipts sediment incasement of heat dissipation lower part and collect, convenient centralized processing.

Further, a drawer-type slag taking box is connected in the slag collecting box in a transverse sliding manner.

Has the advantages that: the slag box can be conveniently slid out and the residue in the slag box can be cleaned.

Furthermore, a limiting block is fixed to the top of the inner wall of the heat exchange cylinder, and a clamping block clamped with the limiting block is fixed to the lower end of the cover body.

Has the advantages that: on the one hand, the cover body is conveniently clamped at the top of the heat exchange cylinder, on the other hand, the limiting block can limit the placing plate, and the placing plate can be prevented from sliding out of the heat exchange cylinder when sliding up.
