Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a ship heat exchanger which is easy to assemble and clean and a method thereof. Background Art

[0002] Heat exchangers, also known as heat exchangers or heat exchange equipment, are devices used to transfer heat from hot fluids to cold fluids to meet specified process requirements. They are an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to their operating process, they can be divided into three categories: partition type, hybrid type, heat storage type or heat recovery type; according to the compactness of their surface, they can be divided into compact type and non-compact type. Heat exchangers for ship exhaust gas scrubbing are widely used in exhaust gas treatment systems of various types of ships, especially those ocean-going ships that need to efficiently treat large amounts of exhaust gas. By installing heat exchangers, ships can significantly reduce exhaust gas temperatures, reduce harmful emissions, and at the same time recover energy and improve energy efficiency.

[0003] After searching, a Chinese patent with announcement number CN210400062U discloses a corrosion-resistant marine shell and tube heat exchanger, comprising a heat exchanger body and end covers arranged at both ends thereof, the inner side walls of the two end covers are fixedly provided with a rubber layer, the outer side wall of one of the end covers is symmetrically connected with an inlet pipe and an outlet pipe, the outlet pipe and the inlet pipe are arranged in an upper and lower distribution, the outlet pipe and the inlet pipe are each provided with a flange at one end away from the heat exchanger body, the inlet pipe is provided with a sleeve matching with its inner wall, the sleeve is fixedly provided with a filter screen at the inner edge of the opening on one side close to the heat exchanger body, the sleeve is fixedly provided with a rectangular ring on the side away from the filter screen, the inner side wall of the flange is provided with a rectangular groove matching with the rectangular ring, the rectangular ring is clamped with the opening of the inlet pipe, the interior of the flange is provided with cavities above and below the rectangular groove, and the interior of the two cavities is provided with a limiting mechanism for fixing the rectangular ring.

[0004] Through the above-mentioned prior art, it can be understood that the traditional ship heat exchanger still has some shortcomings in actual application. For example, the traditional heat exchanger is mainly installed by connecting the two legs welded at the lower end of the shell with fasteners. Since the height of the legs of this heat exchanger is usually fixed, and the support height cannot be adjusted for installation, it is usually necessary to weld a support seat with a specified height when installing in the cabin. Of course, it can also be installed with screws here, and then the legs are connected to the support seat. This assembly form is relatively troublesome. Secondly, since a large number of screw fasteners are needed for fixing during installation, subsequent disassembly, replacement or maintenance also requires a lot of time and effort for the staff to operate.

[0015] A method for using a ship heat exchanger that is easy to assemble and clean, comprising the following steps:

[0016] S1. During initial installation, firstly, the mounting base is installed at the designated position in the ship's cabin by engaging the fasteners with the fixing block with the fixing hole on the mounting base;

[0017] S2, then through measurement, the crank is used to rotate the shaft rod inside the installation groove, so that the second bevel gear outside the shaft rod meshes with the first bevel gear, and at the same time, the third screw connected to the first bevel gear rotates on the upper end of the installation seat, and the rotation of the third screw causes the adjustment seat with a threaded sleeve to slide up and down on the inner side of the sleeve, so that the adjustment seat can be adjusted to a specified height position;

[0018] S3. When the adjustment position is determined, the handle is rotated so that the second screw connected to the handle rotates on the square sleeve, and the rotation of the second screw causes the slider connected to the lower thread to slide. When the clamp at the lower end of the slider is inserted into the gear ring of the crank handle in the adjusted state, the slider can be locked and positioned;

[0019] S4. After the adjustment of the adjustment seat is completed, the lower end of the heat exchanger body is inserted into the matching groove of the adjustment seat through the matching block. At this time, the heat exchanger body is located on the inner side of the upper end of the adjustment seat;

[0020] S5. Next, the connecting block of the connecting frame is inserted into the connecting groove on the corresponding adjusting seat, and the inserting strip on the connecting block is also inserted into the strip groove. During the insertion process, the notch at the upper end of the connecting groove squeezes the inclined surface of the card block extending from the connecting block, so that the card block connecting slide slides inside the installation cavity and squeezes the spring outside the pull rod. When the position of the card block corresponds to the position of the card hole at the connecting groove, the spring resets and pushes the card block connected to the slide plate into the card hole to be fixed.

[0021] S6. After the connecting frame is connected to the adjustment seat, it is only necessary to operate the turning handle above the connecting frame so that the turning handle drives the first screw to extend and retract on the connecting frame. At the same time, the lower end of the first screw rotates to push the clamping block with the clamping groove to slide toward the heat exchanger body until it is clamped to complete the fixation.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, in the present invention, the connecting block of the connecting frame is inserted into the connecting groove on the corresponding adjusting seat, and the inserting strip on the connecting block is also inserted into the strip groove. During the insertion process, the notch at the upper end of the connecting groove squeezes the inclined surface of the card block inserted end extending from the connecting block, so that the card block connecting slide slides inside the installation cavity and squeezes the spring outside the pull rod. When the position of the card block corresponds to the position of the card hole at the connecting groove, the spring resets and pushes the card block connected to the slide plate to be inserted into the card hole to be fixed. Then, the turning handle above the rotating connecting frame is operated to drive the first screw rod to extend and retract on the connecting frame. At the same time, the lower end of the first screw rotates to push the clamping block with the clamping groove to slide toward the heat exchanger body to clamp it, so that the heat exchanger body can be easily assembled on the adjusting seat.

[0024] Secondly, in the present invention, when disassembling later, it is only necessary to pull the handles on the ends of the connecting frame at the same time, so that the slide connected to the handles by the pull rods slides in the installation cavity, and the connecting frame can be removed when the block on the slide is separated from the slot on the adjustment seat, so that the heat exchanger body can be quickly removed for maintenance or replacement;

[0025] Thirdly, in the present invention, the crank handle is used to rotate the shaft rod inside the mounting groove, so that the second bevel gear outside the shaft rod engages with the first bevel gear for transmission, and at the same time, the third screw connected to the first bevel gear rotates on the upper end of the mounting seat, and the rotation of the third screw causes the adjustment seat with a threaded sleeve connected thereto to slide up and down on the inner side of the sleeve, so that the adjustment seat can be conveniently adjusted to a specified height position, and the second screw connected to the handle is rotated on the square sleeve by operating the rotating handle, and the rotation of the second screw causes the slider threaded at the lower end to slide, and when the clamp at the lower end of the slider is inserted into the crank handle disc gear ring in the adjusted state, loosening during installation can be avoided, thereby ensuring the stability of the adjustment seat.

[0044] A method for using a ship heat exchanger that is easy to assemble and clean, comprising the following steps:

[0045] S1. During initial installation, firstly, the mounting base 1 is mounted at a designated position in the ship cabin by engaging the fixing block with the fixing hole 401 on the mounting base 1 with the fastener;

[0046] S2. Then, by measuring, the crank 156 is used to rotate the shaft 155 inside the mounting groove 153, so that the second bevel gear 157 outside the shaft 155 meshes with the first bevel gear 154, and at the same time, the third screw 151 connected to the first bevel gear 154 rotates on the upper end of the mounting seat 1. The rotation of the third screw 151 causes the adjustment seat 3 threadedly connected with the screw sleeve 152 to slide up and down inside the sleeve 2, so that the adjustment seat 3 can be adjusted to a specified height position;

[0047] S3. When the adjustment position is determined, the handle 112 is rotated so that the second screw 114 connected to the handle 112 rotates on the square sleeve 111. The rotation of the second screw 114 causes the slider 113 connected to the lower thread to slide. When the clamping head 115 at the lower end of the slider 113 is inserted into the crank handle 156 in the adjusted state, the disc gear ring can be prevented from loosening and positioned.

[0048] S4, after the adjustment of the adjustment seat 3 is completed, the lower end of the heat exchanger body 5 is inserted into the matching groove 13 of the adjustment seat 3 through the matching block 14, and the heat exchanger body 5 is located at the inner side of the upper end of the adjustment seat 3;

[0049] S5. Next, the connecting block 601 of the connecting frame 6 is inserted into the corresponding connecting groove 302 on the adjusting seat 3. Meanwhile, the inserting strip 602 on the connecting block 601 is also inserted into the strip groove 303. During the insertion process, the notch at the upper end of the connecting groove 302 squeezes the inclined surface of the inserting end of the card block 805 extending from the connecting block 601, so that the card block 805 connected to the slide plate 806 slides inside the installation cavity 801 and squeezes the spring 804 outside the pull rod 802. When the position of the card block 805 corresponds to the position of the card hole 301 at the connecting groove 302, the spring 804 is reset to push the card block 805 connected to the slide plate 806 to be inserted into the card hole 301 to be fixed.

[0050] S6. After the connecting frame 6 is connected to the adjusting seat 3, it is only necessary to operate the turning handle 704 above the rotating connecting frame 6 so that the turning handle 704 drives the first screw 703 to extend and retract on the connecting frame 6. At the same time, the lower end of the first screw 703 rotates to push the clamping block 701 with the clamping groove 702 to slide toward the heat exchanger body 5 until it is clamped to complete the fixation.
