Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a rapid cleaning device for heat exchangers. Background Technology

[0002] A heat exchanger is a device that transfers heat from a hot fluid to a cold fluid. Also known as a heat exchanger, it is widely used in industries such as chemical, petroleum, power, and food processing to achieve processes such as heating, cooling, condensation, or evaporation. Heat exchangers are highly efficient and energy-saving devices that transfer heat between fluids at different temperatures through solid walls or direct fluid contact. Their core function is to regulate fluid temperature to meet production process requirements, such as cooling high-temperature fluids or heating low-temperature fluids, thereby improving energy efficiency. This equipment is indispensable in industrial production and is often used as a heater, cooler, condenser, or evaporator.

[0003] With the continuous advancement of diamond wire cutting technology for monocrystalline silicon in slicing machines, the diameter of diamond wires is constantly decreasing, resulting in thinner silicon wafers. To improve yield and reduce processing costs, the requirements for stable cutting fluid flow rate are becoming more stringent. Without increasing the volume of the cutting fluid tank, the thinner silicon wafers result in increased silicon powder content in the cutting fluid, shortening the clogging time of the plate heat exchanger and thus affecting the cutting flow rate. Under the premise that the alkaline washing cycle of the slicing machine remains unchanged, it is necessary to increase the cleaning frequency of the plate heat exchanger. The disassembly and cleaning cycle of the plate heat exchanger is long and labor-intensive, requiring a large number of personnel. In actual cleaning, switching between cooling and cleaning is quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a rapid heat exchanger cleaning device to address the problems mentioned in the background art. With the continuous advancement of diamond wire cutting technology for monocrystalline silicon wafers, the diameter of diamond wires is constantly decreasing, resulting in thinner silicon wafers. To improve yield and reduce processing costs, the requirements for stable cutting fluid flow are becoming increasingly stringent. Without increasing the volume of the cutting fluid tank, the thinner silicon wafers lead to increased silicon powder content in the cutting fluid, shortening the clogging time of the plate heat exchanger and thus affecting the cutting flow rate. Under the premise that the alkaline washing cycle of the slicing machine remains unchanged, the cleaning frequency of the plate heat exchanger needs to be increased. However, the disassembly and cleaning cycle of the plate heat exchanger is long, labor-intensive, and requires a large number of personnel. Furthermore, switching between cooling and cleaning during actual cleaning is quite cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger rapid cleaning device, comprising a heat exchanger body and water inlet pipes opened on both sides of the upper end of the heat exchanger body, water outlet pipes opened on both sides of the lower end of the heat exchanger body, branch pipes fixedly installed at the upper end of each water inlet pipe, and an adjustment component provided on the side of the heat exchanger body, the adjustment component including a fixed block fixedly installed on the side of the water inlet pipe, a sliding groove first opened inside the fixed block, a movable block slidably connected in the sliding groove first, and a movable component movably arranged inside the movable block.

[0006] Preferably, the movable block has an installation groove on both sides, an opening on the side of each installation groove, and a liquid inlet at the other end of each installation groove. An input pipe is fixedly installed on the outer wall of each liquid inlet.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figure 1 - Figure 3 A rapid cleaning device for a heat exchanger includes a heat exchanger body 1 and inlet pipes 2 opened on both sides of the upper end of the heat exchanger body 1. Outlet pipes 4 are opened on both sides of the lower end of the heat exchanger body 1. Branch pipes 3 are fixedly installed on the upper end of the inlet pipes 2. An adjustment component 5 is provided on the side of the heat exchanger body 1. The adjustment component 5 includes a fixing block 51 fixedly installed on the side of the inlet pipe 2. A sliding groove 52 is opened inside the fixing block 51. A movable block 53 is slidably connected in the sliding groove 52. A movable component 6 is movably arranged inside the movable block 53.

[0021] In this embodiment: In actual use, the movable components 6 inside the movable block 53 have the following functions: the upper end is for cleaning and the lower end is for cooling. When the heat exchanger needs to be cleaned, the movable block 53 inside the sliding groove 52 of the fixed block 51 is pushed downward. When the movable block 53 moves downward along the sliding groove 52, the two sets of movable components 6 are switched. When the upper movable component 6 is connected to the branch pipe 3, the lower movable component 6 is in a closed state. Similarly, when the lower movable component 6 is connected to the branch pipe 3, the upper movable component 6 is in a closed state. In actual use, the heat exchanger quick cleaning device can quickly switch between cooling and cleaning functions by adjusting the component 5 on the side of the heat exchanger body 1, making cleaning convenient.

[0022] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 The movable block 53 has an installation groove 54 on both sides, an opening 55 on the side of the installation groove 54, and an inlet 56 at the other end of the installation groove 54. An input pipe 57 is fixedly installed on the outer wall of the inlet 56.

[0023] The active component 6 includes a slider 61 that is slidably connected in the mounting groove 54. A connecting block 62 is fixedly installed on the side of the slider 61. A connecting groove 63 is formed between the connecting block 62 and the slider 61. The connecting block 62 is slidably connected in the opening 55.

[0024] A connecting pipe 64 is fixedly installed on the side of slider 61. A spring 66 is fixedly installed between the side wall of slider 61 and the inner wall of the mounting groove 54. Several connecting grooves 65 are equidistantly opened on the side of the connecting pipe 64. The spring 66 provides an outward thrust to slider 61.

[0025] A slider 67 is fixedly installed at one end of the connecting pipe 64, and a block 68 is fixedly installed at one end of the slider 67. The block 68 is slidably connected in the liquid inlet 56. Several connecting grooves 69 are equidistantly opened on the side wall of the slider 67. The connection grooves 69 and the connecting groove 65 make the inner and outer walls of the connecting pipe 64 communicate with the interior of the mounting groove 54.

[0026] A mounting block 59 is fixedly installed on the side of the water outlet pipe 4. A second sliding groove 591 is opened on both sides of the mounting block 59. A movable plug 592 is slidably connected in the second sliding groove 591. A connecting rod 58 is fixedly installed between the upper end of the movable plug 592 and the lower wall of the movable block 53. When the movable block 53 moves up and down at the upper end, the movable plug 592 can be moved up and down through the connecting rod 58.

[0027] In this embodiment: When the heat exchanger needs to be cleaned internally, the connecting rod 58 can be pulled down. When the connecting rod 58 moves downward, it causes the lower movable plug 592 to slide down along the second slide groove 591. When sliding downward, it blocks the outlet of the water pipe 4, preventing the cleaning fluid from flowing directly out of the water pipe 4 during subsequent cleaning. When the connecting rod 58 causes the movable block 53 to move downward, the lower movable component 6 is driven downward by the branch pipe 3. When it moves, the connecting block 62 extending into the branch pipe 3 is squeezed and slid into the installation groove 54. When the connecting block 62 is squeezed, it simultaneously pushes the first slider 61 and the connecting pipe 64 into the installation groove 54. At this time, the second slider 67 set inside slides along the installation groove 54 until it contacts the inner wall of the installation groove 54. When the slider 67 slides to the inside of the liquid inlet 56, the blocking block 68 on the side wall of the slider 67 blocks the liquid inlet 56 used for cooling at the lower end. During the downward movement, the connecting block 62 at the upper end is pushed outward by the spring 66 and slides into the branch pipe 3. The slider 67 inside slides outward, and at this time the blocking of the liquid inlet 56 at the upper end is in contact. The cleaning liquid accumulated in the upper input pipe 57 flows into the connecting groove 65 along the liquid inlet 56 and the connecting groove 69, and then flows into the branch pipe 3 along the connecting groove 63. When the heat exchanger needs to be cleaned, the device switches between cooling and cleaning functions through the connecting rod 58. During the switching process, the lower water outlet pipe 4 is automatically blocked. After the cleaning is completed, the device can automatically discharge the cleaning liquid when switching back to heat dissipation.
