Description

Technical Field

[0001] This utility model relates to the field of chiller technology, and in particular to a circulating chiller. Background Technology

[0002] The circulating water chiller is a machine that uses a compressor and heat exchanger to cool the water used in production. It can work in environments with poor water quality and many impurities. At the same time, the circulating water chiller is equipped with an insulated water tank and a water pump, so there is no need to add a cooling tower for heat dissipation, which can save water resources.

[0003] Existing chillers have numerous internal piping lines, and with prolonged use, wear and tear on the internal components becomes increasingly apparent, necessitating regular maintenance. However, because the chiller's casing is designed as a single unit, maintenance requires complete disassembly of the casing, which not only increases the complexity of the operation process but also significantly raises labor costs. Therefore, there is an urgent need for a circulating chiller to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circulating chiller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A circulating chiller includes a chiller body, a sealing plate is provided on the bottom side of the chiller body, and a quick-opening and quick-release mechanism for the sealing plate is provided on the bottom side of the outer wall of the chiller body.

[0007] The quick-release mechanism includes slots at the four corners of the bottom of the outer wall of one side of the chiller body. Each slot has a first circular groove on one side of its inner wall. A movable block is provided inside the slot. A triangular notch is provided at the top of the movable block. A second circular groove is provided on one side of the top of the inner wall of the slot. A limiting post is slidably provided inside the second circular groove. The bottom of the limiting post is located at the bottom of the inner wall of the triangular notch. Each slot has a matching insert block inside. The other side of each insert block is fixed to one of the four corners of the sealing plate. The top and bottom of each insert block have a limiting hole that is compatible with the limiting post. When the insert block is inserted into the slot, the limiting post will be inserted into the limiting hole and limit the sealing plate.

[0008] Preferably, the inner wall of the slot is provided with a horizontal sliding groove at both ends, and a slider is slidably provided inside the horizontal sliding groove. The sides of the two sliders that are close to each other are fixed to the two ends of the moving block.

[0009] Preferably, a fixing rod is fixed to the side of the movable block away from the sealing plate, and the other end of the fixing rod is slidably disposed inside the first circular groove.

[0010] Preferably, one end of a spring is fixed to one side of the movable block, the other end of the spring is fixed to one side of the inner wall of the slot, and the spring is located on the outer surface of the fixing rod.

[0011] Preferably, the sealing plate has a sealing ring on the side closest to the chiller body.

[0012] Preferably, two through slots communicating with the second circular slide are opened on both sides of the chiller body. A connecting block is fixed on the outer wall of one end of each limiting post, and the four connecting blocks are paired. One end of each of the two connecting blocks is rotatably connected to the same U-shaped rod. Hooks are fixed on the top of both sides of the chiller body, and the hooks are located on one side of the through slots. The U-shaped rod can rotate and hang on the outer wall of the hook, and limit the limiting post.

[0013] Preferably, a control panel is provided at the top of one end of the chiller body.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Thanks to the quick-release mechanism, pulling the U-shaped rod moves the corresponding limit post upward, which engages the limit of the insert block. Then, the spring resets the moving block and pushes the sealing plate a distance. At this point, the internal parts of the chiller can be inspected. After inspection, by reinserting the insert block into the slot, the triangular groove gradually pushes the limit post until the bottom of the limit post is flush with the top of the insert block. Then, the limit post is reinserted into the limit hole, thus achieving quick disassembly of the sealing plate and facilitating maintenance of the chiller. The quick-release mechanism makes the disassembly process more stable and controllable, avoiding damage to components or accidental injury caused by forcibly disassembling with tools, reducing safety risks during maintenance, and reducing chiller downtime, thereby minimizing production losses caused by equipment downtime.

The bottom of the limiting post 309 is located at the bottom of the inner wall of the triangular slot 308. Each slot 3 has a matching insert 202 inside. The other side of the insert 202 is fixed to one of the four corners of the sealing plate 2. The top and bottom of the insert 202 have corresponding limiting holes 203. The limiting holes 203 are matched with the limiting posts 309. When the insert 202 is inserted into the slot 3, the limiting post 309 will be inserted into the limiting hole 203 and limit the sealing plate 2.

[0026] In this utility model, both ends of the inner wall of the slot 3 are provided with horizontal sliding grooves 306, and sliders 303 are slidably provided inside the horizontal sliding grooves 306. The sides of the two sliders 303 that are close to each other are fixed to the two ends of the moving block 302. The horizontal sliding grooves 306 and sliders 303 can improve the stability of the moving block 302 when it moves.

[0027] In this utility model, a fixing rod 305 is fixed on the side of the movable block 302 away from the sealing plate 2, and the other end of the fixing rod 305 is slidably disposed inside the first circular groove 301.

[0029] In this utility model, a sealing ring 201 is provided on the side of the sealing plate 2 near the chiller body 1.

[0030] In this utility model, two through grooves 102 communicating with the second circular slide groove 307 are opened on both sides of the chiller body 1. A connecting block 310 is fixed on the outer wall of one end of the limiting post 309, and the four connecting blocks 310 are paired. The same U-shaped rod 4 is rotatably connected to one end of the two connecting blocks 310.

Then rotate the U-shaped rod 4 and move away from the spring 304. Hook 401, due to the weight of the limiting post 309, the limiting post 309 will descend freely, and then the bottom of the limiting post 309 will contact the bottom of the inner wall of the triangular groove 308. After maintenance, align the four inserts 202 with the four slots 3 respectively, and then press the sealing plate 2. The sealing plate 2 will push the four inserts 202 into the inside of the slots 3. At this time, the moving block 302 will move and squeeze the spring 304. The bottom of the limiting post 309 will gradually move on the inclined surface of the triangular groove 308 until it moves to be flush with the top of the insert 202. When the limiting hole 203 moves below the limiting post 309, the limiting post 309 will be inserted into the limiting hole 203 by its own weight and limit the insert 202, thereby limiting the sealing plate 2. By setting the sealing ring 201, the sealing ring 201 will seal one side of the chiller body 1.
