Description

Technical Field

[0001] The utility model relates to the field of box heat exchangers, in particular to a novel inserted tube box heat exchanger. Background Art

[0002] The existing patent (publication number: CN101929808B) proposes a novel inserted tube box heat exchanger, which includes heat exchange tubes, a tube sheet with a diversion cavity, end covers, sealing gaskets, and a heat medium cavity with baffle plates. The heat exchange tubes are straight tubes, and their two ends are connected to the tube sheet. The tube sheet is provided with fastening bolt holes and two rows of through holes. Each port of the heat exchange tube is welded in the through hole and connected to the inner side of the tube sheet. There is a distance between the welding position and the outer end face of the tube sheet. However, for the "multiple baffle plates arranged along the direction of the heat exchange tubes in the shell side" of this device, the flow cross-sectional area of the heat medium is reduced as much as possible, resulting in poor fluidity of the heat medium between the internal baffle plates, insufficient contact between the heat medium and the heat exchange tubes, and affecting the heat exchange efficiency. Summary of the Invention

[0003] Aiming at the above deficiencies of the existing technology, the utility model provides a novel inserted tube box heat exchanger. When heat exchange is carried out, materials enter from the material input pipe and are discharged from the material output pipe, and the heat medium enters from the medium input pipe and flows out from the medium output pipe. The spiral tube adopts a spiral vortex structure, so that the flow stroke of the materials inside the material flow tube is longer, increasing the heat exchange time between the materials and the heat medium. At the same time, the stirring drive motor drives the stirring disc to rotate through the driving wheel. While the stirring disc rotates, it accelerates the flow of the heat medium inside the inner bearing shell, ensuring that the heat medium at each position is in full contact with the spiral tube, further increasing the heat exchange efficiency and making the heat exchange effect of this device better.

[0004] The purpose of the utility model is achieved through the following technical solutions:

The material flow pipe is arranged inside the inner bearing shell and consists of three main parts: a spiral pipe disc, an inner spiral disc connecting pipe, and an outer spiral disc connecting pipe. Five groups of spiral pipe discs are arranged longitudinally at intervals. The spiral pipe discs are sequentially numbered as No. 1, No. 2, No. 3, No. 4, and No. 5 from top to bottom. The inner spiral disc connecting pipe is located inside the spiral pipe disc, and the outer spiral disc connecting pipe is located outside the spiral pipe disc. No. 5 is connected to No. 4, and No. 3 is connected to No. 2 through the inner spiral disc connecting pipe.

One side of the No. 5 spiral pipe disc has a material input pipe, and the material input pipe passes through the inner feed pipe installation hole and is fixed. The top of the No. 1 spiral pipe disc has a material output pipe.

[0006] The material output pipe passes through the output pipe connection hole and is fixed. The outer spiral disc connecting pipe is inserted into the connecting pipe installation groove and fixed.

The agitation disc is adapted to the agitation disc connection groove. The agitation disc is connected to the agitation disc connection groove, and the agitation disc rotates inside the agitation disc connection groove. The side surface of the agitation disc has an outer connection groove, which is evenly arranged around the agitation disc. The surface of the agitation disc has agitation plates, which are evenly arranged around the agitation disc. Inside the agitation disc, there is a drive wheel connection groove, which surrounds the inner spiral disc connecting pipe. Inside the upper drive rod connecting block, there is an upper drive rod connection groove. The bottom of the inner bearing shell has a motor connection groove, a medium input pipe, and a fastening screw. The motor connection groove, the medium input pipe, and the fastening screw are arranged in a straight line in sequence. Inside the motor connection groove, there is a lower drive rod connection groove.

[0007] The top of the drive shaft is rotationally connected to the upper drive rod connection groove, and the bottom of the drive shaft is rotationally connected to the lower drive rod connection groove. The agitation drive motor is inserted into the motor connection groove and fixed. The drive shaft of the agitation drive motor is fixedly connected to the drive shaft. The middle part of the drive shaft is fixedly connected to four groups of drive wheels. The drive wheels correspond to the spiral pipe discs at various positions. The drive wheels are adapted to the drive wheel connection grooves. The drive wheels are connected to the drive wheel connection grooves, and the drive wheels are pressed against the inner side of the drive wheel connection grooves.

[0008] Beneficial effects: 1. When the present utility model conducts heat exchange, the material enters from the material input pipe and is discharged from the material output pipe, and the heat medium enters from the medium input pipe and flows out from the medium output pipe. The spiral tube plate adopts a spiral structure, so that the flow path of the material inside the material flow pipe is relatively long, increasing the heat exchange time between the material and the heat medium. At the same time, the stirring drive motor drives the stirring disc to rotate through the drive wheel. While the stirring disc rotates, it accelerates the flow of the heat medium inside the inner bearing shell, ensuring that the heat medium at each position is in full contact with the spiral tube plate, further increasing the heat exchange efficiency and making the heat exchange effect of this device better.

[0009] 2. The surface of the stirring disc of the present utility model is provided with stirring plates, which can further accelerate the flow efficiency of the heat medium in the same layer, further increasing the heat exchange efficiency of this device. At the same time, the side of the stirring disc has an external communication groove, and both the external communication groove and the drive wheel connection groove can reduce the flow efficiency of the heat medium flowing downward, avoiding waste caused by the heat medium flowing out too fast before completing heat exchange.

[0010] 3. Heat insulation gaskets are provided between the outer side of the inner bearing shell and the inner side of the outer protective shell of the present utility model, which can avoid excessive heat exchange between the heat medium contained inside the inner bearing shell and the outside world, resulting in waste of energy and reducing the use cost of this device.

[0011] 4. Both the inner side of the drive wheel connection groove and the outer side of the drive wheel of the present utility model are of V-shaped structures, so that when the drive wheel contacts the drive wheel connection groove, the contact area is larger, making it more difficult for the drive wheel to slip when driving the stirring disc to rotate, and ensuring the transmission efficiency of the drive wheel to the stirring disc.
