Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration-related equipment, and more specifically to a cooling water filtering and recycling device for an ice maker. Background Art

[0002] Ice maker is a refrigeration mechanical equipment that generates ice by cooling water through the evaporator with the refrigerant of the refrigeration system. It uses the refrigeration system and water as a carrier to make ice by passing through a certain device under power-on state. The shape of the ice cubes generated is different according to the principle and production method of the evaporator. People generally classify ice makers into granular ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc. according to the shape of ice.

[0024] The four cooling water heat exchange components 4 can effectively increase the area of ​​heat exchange, thereby ensuring the efficiency of heat exchange. The sealing component 5 is used to ensure that the cooling water heat exchange component 4 and the cold water contact part are in a sealed state, thereby avoiding the loss caused by the dissipation of cold air. The internal circulation component 6 is used to reflux and re-cool the cooling water with insufficient cooling temperature until the cooling water meets the cooling temperature.

[0025] The refrigeration sealed box 1 includes a basic shell 101. The basic shell 101, the cooling water heat exchange component 4 and the sealing component 5 can form a cold chamber, and then cooperate with the cold air inlet pipe 2 and the cold air outlet pipe 3 to achieve circulating cooling of the cold air.

[0026] One side of the base shell 101 is connected to the water inlet side shell 102 by bolts, and the other side of the base shell 101 is connected to the water outlet side shell 103 by bolts. Both the water inlet side shell 102 and the water outlet side shell 103 can be disassembled by bolts, which can effectively reduce the difficulty of assembling or disassembling the entire refrigeration sealed box 1.

[0027] The top ends of the base shell 101 , the water inlet side shell 102 , and the water outlet side shell 103 are connected with a top cover 104 by bolts, and the top cover 104 is used to form a seal on the top of the refrigeration sealed box 1 .

[0028] The bottom ends of the base shell 101 , the water inlet side shell 102 , and the water outlet side shell 103 are connected with a bottom cover 105 by bolts, and the top cover 104 is used to form a seal at the bottom of the refrigeration sealed box 1 .

[0029] The cooling water heat exchange component 4 includes a high-position L-shaped plate 401 and a low-position L-shaped plate 402. The high-position L-shaped plate 401 and the low-position L-shaped plate 402 are fixed to the base shell 101 by bolts. The high-position L-shaped plate 401 and the low-position L-shaped plate 402 are arranged in parallel and in opposite directions. The high-position L-shaped plate 401 and the low-position L-shaped plate 402 can be easily installed or separated from the base shell 101 by bolt fixing.

[0030] A multi-channel copper water pipe 403 is arranged between the high-position L-shaped plate 401 and the low-position L-shaped plate 402. The multi-channel copper water pipe 403 is in contact with the cold air to complete heat exchange.

[0031] A down pipe 404 with a valve is provided at the bottom end of the multi-channel copper water pipe 403. When the cooling water needs to be replaced, the cooling water in the current water path can be discharged through the down pipe 404 with a valve.

[0032] One end of the multi-channel copper water pipe 403 is provided with a first water inlet pipe 405, a second water inlet pipe 406 and a return water inlet pipe 407 from top to bottom, and the first water inlet pipe 405, the second water inlet pipe 406 and the return water inlet pipe 407 all pass through the high-position L-shaped plate 401.

[0033] When the cooling water flows at a low speed, only the first water inlet pipe 405 and the main drain pipe 408 are opened to form the circulation of cooling water. When the cooling water flows at a high speed, the first water inlet pipe 405, the second water inlet pipe 406, the main drain pipe 408 and the spare drain pipe 409 are all opened to avoid excessive water pressure inside the multi-channel copper water pipe 403.

[0034] The main drain pipe 408 is connected to a temperature detector 410, and the temperature detector 410 is connected to the backup drain pipe 409. A binary valve 411 is fixedly provided at one end of the temperature detector 410. The first output port of the binary valve 411 is fixedly connected to the main outlet pipe 412, and the second output port of the binary valve 411 is fixedly connected to the reflux outlet pipe 413.

[0035] When the cooling water is cooled and discharged, the temperature detector 410 and the binary valve 411 work in coordination. The temperature detector 410 detects whether the cooling temperature meets the requirements. If it meets the requirements, the binary valve 411 controls the cooling water to be discharged from the main outlet pipe 412. If it does not meet the requirements, the binary valve 411 controls the cooling water to be discharged from the reflux outlet pipe 413, thereby completing the water circulation.

[0036] The water inlet ends of the first water inlet pipe 405 and the second water inlet pipe 406 are connected to a water inlet collecting water tank 414, one end of which is fixedly connected to a cooling water inlet water guide pipe 415, which passes through the water inlet side shell 102 and is connected to a water inlet filter 416.

[0037] The cooling water is first filtered through the water inlet filter 416 , and then introduced into the water inlet collecting water tank 414 through the water guide pipe 415 , and then distributed to each of the first water inlet pipe 405 and the second water inlet pipe 406 .

[0038] The water outlet ends of the four main water outlet pipes 412 are connected to a water outlet collecting water tank 417 , one end of which is fixedly connected to a cooling water outlet water conduit 418 . The cooling water outlet water conduit 418 passes through the water outlet side shell 103 and is connected to a water outlet filter 419 .

[0039] When the cooling water is finished cooling and discharged, it is first collected in the outlet collecting water tank 417, then passes through the cooling water outlet water pipe 418, is filtered in the outlet filter 419, and is discharged, and finally is guided back from the cooling water inlet water pipe 415 to complete the circulation of the cooling water.

[0040] The sealing assembly 5 includes six No. 1 sealing plates 501 and four No. 2 sealing plates 502, three No. 1 sealing plates 501 are arranged between two high-position L-shaped plates 401, three No. 1 sealing plates 501 are arranged between two low-position L-shaped plates 402, two No. 2 sealing plates 502 are arranged between the high-position L-shaped plate 401 and the basic shell 101, and two No. 2 sealing plates 502 are arranged between the low-position L-shaped plate 402 and the basic shell 101, and the connections between the No. 1 sealing plate 501, the No. 2 sealing plate 502, the high-position L-shaped plate 401, the low-position L-shaped plate 402, and the basic shell 101 are all fixed by bolts, and the top ends of the sides of the No. 1 sealing plate 501, the No. 2 sealing plate 502, the high-position L-shaped plate 401, and the low-position L-shaped plate 402 are connected with sealing covers 503 by bolts.

[0041] Sealing plate No. 1 501, sealing plate No. 2 502, and sealing cover 503 are all plate-shaped or cover-shaped structures with sealing rubber. When used together, the three can form a sealed heat exchange space at the location of the multi-channel copper water pipe 403, thereby maximizing the heat exchange effect.

[0042] The internal circulation component 6 includes an internal circulation water pump 601, one end of the internal circulation water pump 601 is fixedly connected to a No. 1 return water tank 602, one end of the No. 1 return water tank 602 is fixedly connected to four long return pipes 603, the long return pipes 603 are connected to the return water outlet pipe 413 through a flange, the other end of the internal circulation water pump 601 is fixedly connected to a No. 2 return water tank 604, one end of the No. 2 return water tank 604 is fixedly connected to four return elbows 605, the return elbows 605 are connected to the return water inlet pipe 407 through a flange, the internal circulation water pump 601, the No. 1 return water tank 602, and the No. 2 return water tank 604 are all fixed on the basic shell 101.

[0043] When the cooling water temperature is insufficient, except for the return water inlet pipe 407 and the return water outlet pipe 413, the valves of other pipes are closed. At this time, the internal circulation water pump 601 is started, and the cooling water passes through the return water outlet pipe 413 and the return long pipe 603 in turn, and is collected at the No. 1 return water tank 602, and then passes through the internal circulation water pump 601, the No. 2 return water tank 604, and is diverted at the return elbow 605, and finally introduced from the return water inlet pipe 407 into the respective multi-channel copper water pipes 403 to complete secondary cooling until the cooling meets the requirements.

[0044] Embodiment 2: Based on the above embodiment 1, further description is given.

[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Specifically, the basic shell 101 includes two side sealing plates 1011 , and a broken line sealing plate 1012 is fixed between the two side sealing plates 1011 .

[0046] The two side sealing plates 1011 and the broken line sealing plate 1012 form an integrated structure.

[0047] Specifically, a plurality of through holes 1013 for the passage of pipelines are provided on the side sealing plate 1011 and the folded line sealing plate 1012 , and a sealing rubber pad 1014 is sleeved inside the through holes 1013 .

[0048] To ensure smooth passage of the pipeline, it is used in conjunction with the sealing gasket 1014 so that the sealing will not be damaged when passing through the pipeline.

[0049] Specifically, the base shell 101, the water inlet side shell 102, and the water outlet side shell 103 form a semi-enclosed shell structure, the top cover 104 is clamped on the outer top of the semi-enclosed shell structure, and the two are fixed by bolts.

[0051] In this way, the top cover 104 and the bottom cover 105 can be used to improve the restraining effect on the semi-enclosed shell structure, thereby improving the stability of the entire refrigeration sealed box 1 after assembly.

[0052] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig. 9 and Fig.10 Specifically, the multi-channel copper water pipe 403 includes an inlet end water collecting pipe 4031 close to the high-position L-shaped plate 401 and an outlet end water collecting pipe 4032 close to the low-position L-shaped plate 402, and a plurality of long heat exchange tubes 4033 are arranged between the inlet end water collecting pipe 4031 and the outlet end water collecting pipe 4032.

[0054] The first water inlet pipe 405 , the second water inlet pipe 406 and the return water inlet pipe 407 are all fixed to the side of the water inlet end collecting pipe 4031 , and the main drainage pipe 408 and the backup drainage pipe 409 are all fixed to the side of the water outlet end collecting pipe 4032 .

[0055] The cooling water in the water collecting pipe 4031 at the water inlet end passes through the long heat exchange pipe 4033 and exchanges heat, and then gathers at the water collecting pipe 4032 at the water outlet end, so as to facilitate the control of the flow direction of the water.

[0056] Specifically, there are ten long strip heat exchange tubes 4033, and all of them are inclined.

[0057] The water inlet height of the long strip heat exchange tube 4033 is higher than the water outlet height.

[0058] The design of ten long heat exchange tubes 4033 can facilitate fully increasing the heat exchange area and controlling the height of the water inlet and outlet, so that the cooling water and the impurities that may be contained therein can flow to the outlet water collecting pipe 4032. The valved downpipe 404 is at the bottom of the outlet water collecting pipe 4032 and is at the lowest height. The valve is electronically controlled.

[0060] A one-way valve 4091 is fixedly provided on the backup drain pipe 409 and close to the temperature detector 410 .

[0061] The opening and closing of the water channels of the main drain pipe 408 and the backup drain pipe 409 are controlled by the solenoid valve 4081, and then the flow direction of water in the backup drain pipe 409 is controlled by the one-way valve 4091 to prevent the water in the main drain pipe 408 from flowing back through the backup drain pipe 409.

[0066] The flange connection method can facilitate the installation and disassembly of the above structure. When the above flanges are disconnected and the corresponding bolts are removed, the corresponding high-position L-shaped plate 401, low-position L-shaped plate 402, and multi-channel copper water pipe 403 can be dismantled to achieve the replacement of damaged high-position L-shaped plate 401, low-position L-shaped plate 402, and multi-channel copper water pipe 403.

[0067] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11 and Fig.12 Specifically, the first sealing plate 501 is in an I-shape, and the width of the first sealing plate 501 is twice that of the second sealing plate 502 .

[0068] The I-shaped structure of the first sealing plate 501 can be inserted into the gap of the high-position L-shaped plate 401 or the low-position L-shaped plate 402, thereby improving the sealing effect.

[0069] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig.13 Specifically, an annular pipe 6031 is provided on the long return pipe 603, and the annular pipe 6031 is located on the side of the down pipe 404 with a valve.

[0070] The annular pipe 6031 can bypass the return water from the valved downpipe 404 to avoid interference.

[0071] The valved down pipe 404 is connected to a threaded short water pipe 4041 through a flange, the threaded short water pipe 4041 is threadedly connected to a threaded long water pipe 4042 , and the threaded long water pipe 4042 passes through the bottom cover 105 and reaches below the bottom cover 105 .

[0072] The valved downpipe 404, the threaded short water pipe 4041, and the threaded long water pipe 4042 are separable from each other, and after the separation is completed, the multi-channel copper water pipe 403 can be easily taken out and replaced.

[0073] Working principle: When the cooling water of the ice maker completes one cycle and returns to the initial position, the device is used to re-cool the cooling water.

[0074] First, the cooling water is filtered through the water inlet filter 416, and then enters the water inlet collecting tank 414 from the cooling water inlet water pipe 415. After being diverted, it enters the multi-channel copper water pipe 403 from the first water inlet pipe 405 or the second water inlet pipe 406 to wait for heat exchange. At the same time, the cold air for heat exchange enters from the cold air inlet pipe 2, and the cold air completes heat exchange with the cooling water in the multi-channel pipe, and then is discharged from the main drain pipe 408 or the backup drain pipe 409 and passes through the temperature detector 410.

[0075] Then, the cooling water that has completed the heat exchange is detected by the temperature detector 410. At this time, the cooling water that meets the cooling requirements is controlled by the binary valve 411 to be discharged from the main outlet pipe 412, collected at the outlet collecting water tank 417, and then passed through the cooling water outlet water pipe 418 and the outlet filter 419 to complete the filtration, and then the second circulation can be carried out.

[0076] The cooling water that does not meet the cooling requirements is controlled by the two-way valve 411 to be discharged from the reflux outlet pipe 413, and then the cooling water passes through the reflux long pipe 603 in turn and is collected in the No. 1 reflux water tank 602. Then, it is driven by the internal circulation water pump 601, and the cooling water reaches the No. 2 reflux water tank 604 and is diverted. The diverted cooling water passes through the reflux elbow 605 and the reflux inlet pipe 407 and returns to the multi-channel copper water pipe 403 for secondary heat exchange until the final cooling water meets the usage requirements.

[0077] In this way, the device can complete the filtering, recycling and reuse of the cooling water in the ice maker.

[0078] The multi-channel copper water pipe 403 in the device is the main cooling structure. If the structure is damaged, the bolts connected to the structure can be removed to remove the structure and replace it with a new one, ultimately ensuring the heat exchange effect.

[0079] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
