Description

Technical Field

[0001] The invention relates to the technical field of plate heat exchangers, and in particular to a temperature-controllable plate heat exchanger. Background Art

[0002] A plate heat exchanger is a high-efficiency heat exchanger with two flow channels formed between multiple plates, which can be used for liquid-liquid and liquid-steam heat exchange. During use, the heat exchange effect of the heat exchanger will be regulated as required, that is, temperature control. The common existing temperature control method is to regulate the flow rate. The corresponding temperature control structure is divided into a mechanical temperature control structure and an intelligent temperature control element. At present, the mechanical temperature control structure is still the most common temperature control method, but the existing mechanical temperature control still has the following shortcomings: the flow rates of the two liquid inlet pipes are controlled separately, requiring two separate control structures, and the operation is more easily affected by the installation position of the heat exchanger. For example, when it is installed directly on the ground, the control structure below needs to be used by squatting, which may cause certain inconveniences in operation, especially when the flow rates of the two liquid inlet pipes need to be adjusted.

At the same time, other structures can also be used to replace the magnetic attraction, such as a rod body threadedly installed on the adjusting disk 40, and a tightening block is arranged at one end of the rod body. When it is not necessary to rotate, the rod body can be rotated by thread so that the tightening block and the adjusting seat 17 are tightened.

[0056] Reference Figure 1-Figure 22 The adjusting telescopic member includes a rotating block 35, an annular stepped groove 43, a screw 36, a fixed rod 37, and a sliding assembly.

In the specific setting, the moving distance of the slider 2 38 on the limit groove 39 is limited, so that when it is located at one end, the gear ring 1 22 is meshed with the large gear 27, so that when it is located at the other end, the gear ring 25 is meshed with the small gear 26; the following methods can be used to further improve the accuracy of meshing;

[0057] First, the number of teeth is limited, such as the number of teeth of the gear ring 1 22 and the gear ring 2 25 is the same, and the number of teeth of the pinion 26 and the large gear 27 is the same; second, the rotation angle of the regulating disk 40 is limited, requiring that the angle of each rotation needs to be an integer multiple of the angle between two adjacent teeth, such as the combination of gears and racks, a gear is set on the outside of the regulating disk 40 through a one-way bearing, and then a rack is slidably set on the regulating seat 17, the rack is meshed with the gear, and the movement amplitude of the rack can make the regulating disk 40 rotate a specific angle, such as three times the angle between two adjacent teeth, to meet the rotation requirements; third, a structure with a damping effect can be set on the inner wall of the pinion 26 and the regulating seat 17, so that the pinion 26 will not rotate with the corresponding transmission shaft 18 when it does not need to rotate, such as two vertical rods are fixed on the inner wall of the regulating seat 17, and the lower ends of the vertical rods are against the surface of the corresponding pinion 26, so that the pinion 26 meets the use requirements.

By using the strip rods 42 in combination with the rotatable circular blocks, the shaft body 41 can be supported as required without affecting the rotation of the shaft body 41 and the relative sliding when required.

[0059] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0060] The working principle of the present invention is as follows: in the initial state, the second gear ring 25 is meshed with the two pinions 26 at the same time;

[0061] Regulation of a single temperature control tube 10: Apply a rotational force to the regulating disk 40 by hand, the regulating disk 40 rotates through the shaft body 41 to drive the disc 32 to rotate, the disc 32 rotates through the rod 31 to drive the mounting ring 24 fixedly connected thereto to rotate, the mounting ring 24 rotates to drive the gear ring 25 fixedly connected thereto to rotate, the gear ring 25 rotates to drive the corresponding pinion 26 to rotate, due to the arrangement of the two one-way bearings, the regulating disk 40 rotates in different directions, and will drive the two transmission shafts 18 to rotate separately; for example, when rotating clockwise, the upper one-way bearing is in a self-locking state, at which time the upper transmission shaft 18 can rotate, and the lower one-way bearing is in a rotatable state, at which time the lower transmission shaft 18 will not rotate, on the contrary, when the regulating disk 40 rotates counterclockwise, the upper transmission shaft 18 does not rotate, and the lower transmission shaft 18 rotates;

[0062] The transmission shaft 18 rotates and drives the corresponding reciprocating screw 45 to rotate through the cooperation of the two bevel gears 19. The reciprocating screw 45 rotates and drives the movable plate 12 to move through the rod 13. The movable plate 12 moves and drives the flow control plate 14 through the rod 13 to block and seal the connection between the temperature control tube 10 and the connecting tube 11 as required, thereby playing a regulating role. At the same time, due to the setting of the reciprocating screw 45, the reciprocating movement of the movable plate 12 can be controlled when it rotates in one direction. In specific operation, the rotation angle or number of turns of the regulating plate can be set to control the movement amplitude of the movable plate 12.

[0063] Simultaneous regulation of the two temperature control tubes 10: a rotational force is applied to the screw rod 36 by hand, so that the screw rod 36 drives the regulating disk 40 to move outward, and the outward movement of the regulating disk 40 drives the shaft body 41, the disc 32, the rod 31, the mounting ring 24 and the gear ring 25 fixed thereto to move outward together, and the mounting ring 24 moves through the rod 23 to drive the mounting ring 1 21 to move, and the movement of the mounting ring 1 21 drives the gear ring 1 22 to move;

[0064] When the regulating disk 40 moves to the maximum position, the gear ring 1 22 is fully meshed with the large gear 27, and the gear ring 25 is completely separated from the small gear 26. In the specific setting, the gear ring 1 22 is in contact with the large gear 27 before the gear ring 25 is completely separated from the small gear 26. Then a rotational force is applied to the regulating disk 40. At this time, the regulating disk 40 rotates through the shaft 41, the disc 32, the rod three 31, the mounting ring 24, the rod two 23, and the mounting ring 1 21 to drive the gear ring 1 22 to rotate. The rotation of the gear ring 1 22 will drive the two large gears 27 to rotate at the same time, thereby causing the two transmission shafts 18 to rotate at the same time, thereby achieving the effect of simultaneous regulation.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
