Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen recovery devices, and particularly relates to a nitrogen recovery device for producing mobile phone rubber foamed sponge. Background Technique

[0002] Nitrogen pressure storage is used for the high-speed and high-pressure injection action of an injection molding machine, generally for the molding of thin-walled products such as light guide plate connectors. First, underfilled injection molding means that the mold cavity is not filled with the molten plastic completely. At this time, high-pressure nitrogen is used to push the unfrozen molten plastic forward until the cavity is filled, which plays a role in saving raw materials. Second, the pressure holding function. The products of traditional injection molding completely rely on the clamping force of the injection molding machine, which requires a large tonnage of the injection molding machine. After using nitrogen, the tonnage of the injection molding machine can be reduced and the same products can still be produced. Nitrogen is also used to assist in the production of mobile phone rubber foamed sponge.

[0003] In order to save costs, and since nitrogen itself is an inert gas and not easy to react, nitrogen will be recycled after use. Before the nitrogen is recycled, it is usually passed into a treatment solution to intercept the impurities in it and react with and absorb the harmful or odorous substances in it, making the treated nitrogen convenient for use. However, the nitrogen treated by the solution has a high water content. If the water in it is not fully absorbed, it will cause adverse effects in subsequent use, such as causing equipment corrosion or damaging the performance of the produced sponge due to the presence of water. Therefore, in view of the above problems, a nitrogen recovery device for producing mobile phone rubber foamed sponge is proposed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a nitrogen recovery device for producing mobile phone rubber foamed sponge. The nitrogen recovery device is provided with a condensation box and a drying box. The condensation plate in the condensation box can condense most of the water in the gas into liquid at low temperature after the gas flows through, greatly reducing the water content in the gas. Subsequently, the gas passes through the drying box, and the drying plate arranged in it can further absorb the remaining water in the gas, thereby greatly reducing the water content in the outflowing gas and facilitating the normal use of the subsequent nitrogen, solving the technical problem that the nitrogen treated by the solution in the prior art has a high water content and will affect the normal subsequent use of nitrogen.

[0005] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0006] A nitrogen recovery device for the production of mobile phone rubber foamed sponge, comprising a solution treatment tank for filtering waste or impurities in nitrogen, a condensation tank for condensing moisture in the recovered gas, and a drying tank for absorbing moisture in the recovered gas. Among them, the above three are hermetically connected through a connecting pipe. In addition, the condensation tank includes a vertical tank housing, and a number of condensation plates are inclined in the vertical tank housing. The drying tank includes a horizontal tank housing, and a number of groups of strip-shaped insertion rails are arranged in the horizontal tank housing, and drying plates are slidably inserted into the strip-shaped insertion rails.

[0007] Through the above structural form, the nitrogen recovery device is provided with a condensation tank and a drying tank. Among them, the condensation plates in the condensation tank can condense most of the moisture in the gas into liquid at low temperature after the gas flows through, greatly reducing the water content in the gas. Subsequently, the gas passes through the drying tank, and the drying plates arranged therein can further absorb the remaining moisture in the gas, thereby greatly reducing the water content in the outflowing gas and facilitating the normal use of nitrogen in the follow-up; In particular, the drying plates are inserted into the strip-shaped insertion rails, and this installation method can quickly complete the replacement of the drying plates when the drying plates absorb too much moisture and cause a serious decline in the water absorption performance.

[0008] In a possible implementation manner, the condensation plate includes a condensate water curved pipe, and water inlets and outlets are hermetically connected to both ends of the condensate water curved pipe respectively, and an aluminum plate housing in close contact is sleeved outside the condensate water curved pipe.

[0009] Through the above structural form, cold water input externally flows in the condensate water curved pipe, which can continuously take away the heat of the aluminum plate housing, significantly reducing its temperature, so that the moisture in the nitrogen can be quickly condensed and liquefied when contacting the aluminum plate housing, playing a role in removing the moisture in the gas.

[0010] In a possible implementation manner, the water inlet is hermetically connected to the output port of an external chiller, and the water outlet is hermetically connected to the input port of the external chiller.

[0011] Through the above structural form, an external chiller can be used to complete the circulation of the cold water in the condensate water curved pipe to ensure that it can continuously take away the heat of the aluminum plate housing.

[0012] In a possible implementation manner, the drying plate includes a frame, a porous water absorption plate is embedded in the frame, and an outer sealing plate is fixedly connected to the outer end of the frame. When the frame is completely inserted, the outer sealing plate can be in close contact with the outer wall of the horizontal tank housing.

[0013] With the above structural form, the residual moisture in the gas can be absorbed by the porous water absorption plate, so that the water content in the discharged nitrogen is relatively low. Moreover, the frame can protect the edge of the porous water absorption plate and prevent it from being worn during the plugging process. In addition, the outer sealing plate can ensure the overall sealing of the drying box and prevent nitrogen from leaking.

[0014] In a possible implementation manner, there is a gas passing port left between the upper end of the condensation plate and the vertical box housing, and a water dripping port left between the lower end of the condensation plate and the vertical box housing. An air flow guide plate sloping towards the connection part of the connecting pipe is arranged at the top inside the vertical box housing.

[0015] With the above structural form, most of the nitrogen can flow upward through the gas passing port and complete heat exchange with the condensation plate during the rising process. At the same time, part of the liquefied water will drip onto the upper surface of the condensation plate, and this part of the water will flow down through the water dripping port and will not accumulate on the upper surface of the condensation plate.

[0016] In a possible implementation manner, a rectangular through hole is opened at the rear side of the bottom of the vertical box housing, and a water collecting drawer is slidably arranged therein. When the water collecting drawer is fully inserted, its outer end can be in close contact with the outer wall of the vertical box housing.

[0017] With the above structural form, the water collecting drawer can be used to collect the water droplets after condensation, and its slidable structural form can facilitate pulling out to pour the collected water.

[0018] In a possible implementation manner, the solution treatment box includes a liquid storage box, which is divided into several mutually sealed spaces by arranging partitions, and a treatment solution is placed therein. And each space is communicated through a sinking pipe.

[0019] With the above structural form, a multi-purpose treatment solution can be used to react and absorb the impurities in the nitrogen, improving the purity of the discharged nitrogen.

[0020] In a possible implementation manner, an air inlet pipe is hermetically connected to the front end of the condensation box, and an air outlet pipe is hermetically connected to the rear end of the drying box. Among them, a humidity sensor is arranged inside the air outlet pipe.

[0021] With the above structural form, the water content in the discharged nitrogen can be monitored by the humidity sensor, providing a reference basis for the user to adjust the power of the external cold water unit and judge whether it is necessary to replace the drying plate.

[0022] In summary, the present utility model has the following beneficial technical effects:

[0023] The nitrogen recovery device is provided with a condensation box and a drying box. The condensation plate in the condensation box can condense most of the moisture in the gas into liquid at low temperature after the gas flows through, greatly reducing the water content in the gas. Subsequently, the gas passes through the drying box, and the drying plate arranged therein can further absorb the remaining moisture in the gas, thereby greatly reducing the water content in the outflowing gas and facilitating the normal use of the subsequent nitrogen. Particularly, the drying plate is inserted into the strip-shaped insertion rail. This installation method can quickly replace the drying plate when the drying plate absorbs too much moisture and its water absorption performance seriously deteriorates. Description of the Drawings

Detailed Embodiments

[0031] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0032] Such as Figure 1 - Figure 3As shown in the figure, a nitrogen recovery device for the production of mobile phone rubber foamed sponge provided in this embodiment includes a solution treatment tank 1 for filtering waste or impurities in nitrogen, a condensation tank 2 for condensing and recovering moisture in the gas, and a drying tank 3 for absorbing moisture in the recovered gas. Among them, the above three are hermetically connected through a connecting pipe 4. Through the above structural form, the combination of the condensation tank 2 and the drying tank 3 can fully absorb the moisture in nitrogen.

[0033] The condensation tank 2 includes a vertical tank housing 21, and several condensation plates 22 are inclined in the vertical tank housing 21. The drying tank 3 includes a horizontal tank housing 31, and several groups of strip-shaped insertion rails 32 are arranged in the horizontal tank housing 31. Drying plates 33 are slidably inserted into the strip-shaped insertion rails 32. Through the above structural form, the nitrogen recovery device is provided with a condensation tank 2 and a drying tank 3. Among them, the condensation plates 22 in the condensation tank 2 can condense most of the moisture in the gas into liquid at low temperature after the gas passes through, greatly reducing the water content in the gas. Subsequently, the gas passes through the drying tank 3, and the drying plates 33 arranged therein can further absorb the remaining moisture in the gas, thereby greatly reducing the water content in the outflowing gas and facilitating the normal use of nitrogen in the follow-up; In particular, the drying plates 33 are inserted into the strip-shaped insertion rails 32, and this installation method can quickly replace the drying plates 33 when the drying plates 33 absorb too much moisture and the water absorption performance drops severely.

[0034] As Figure 4 shown in the figure, the condensation plate 22 includes a condensate water curved pipe 221. Water inlets 222 and water outlets 223 are hermetically connected to both ends of the condensate water curved pipe 221 respectively. An aluminum plate housing 224 in close contact is sleeved outside the condensate water curved pipe 221. Through the above structural form, cold water input from the outside flows in the condensate water curved pipe 221, which can continuously take away the heat of the aluminum plate housing 224, significantly reducing its temperature, so that when the moisture in nitrogen contacts the aluminum plate housing 224, it can be quickly condensed and liquefied, playing a role in removing moisture in the gas.

[0035] Among them, the water inlet 222 is hermetically connected to the output port of an external chiller, and the water outlet 223 is hermetically connected to the input port of the external chiller. Through the above structural form, the external chiller can be used to complete the circulation of the cold water in the condensate water curved pipe 221 to ensure that it can continuously take away the heat of the aluminum plate housing 224.

[0036] As Figure 3As shown in the figure, the drying plate 33 includes a frame 331, a porous water-absorbing plate 332 is embedded in the frame 331, and an outer sealing plate 333 is fixedly connected to the outer end of the frame 331. When the frame 331 is completely inserted, the outer sealing plate 333 can be in close contact with the outer wall of the horizontal box housing 31. Through the above structural form, the porous water-absorbing plate 332 can absorb the residual moisture in the gas, so that the water content in the discharged nitrogen is relatively low. Moreover, the frame 331 can protect the edge of the porous water-absorbing plate 332 to prevent it from being worn during the insertion and extraction process. In addition, the outer sealing plate 333 can ensure the overall sealing of the drying box 3 and avoid the leakage of nitrogen.

An air flow guide plate 25 sloping towards the connection part of the connecting pipe 4 is arranged at the top inside the vertical box housing 21. Through the above structural form, most of the nitrogen can flow upward through the gas passing port 241 and complete heat exchange with the condensation plate 22 during the rising process. At the same time, part of the liquefied water will drip onto the upper surface of the condensation plate 22, and this part of the water will flow down through the water dripping port 242 and will not accumulate on the upper surface of the condensation plate 22.

[0038] Among them, a rectangular through hole is opened at the rear side of the bottom of the vertical box housing 21, and a water collecting drawer 23 is slidably arranged therein. When the water collecting drawer 23 is completely inserted, its outer end can be in close contact with the outer wall of the vertical box housing 21. Through the above structural form, the water collecting drawer 23 can collect the condensed dripping water, and at the same time, its slidable structure form is convenient for pulling out to pour the collected water.

[0039] As Figure 5 shown in the figure, the solution treatment tank 1 includes a liquid storage tank 11, which is divided into several mutually sealed spaces by a partition plate 12, and a treatment solution is placed therein, and each space is communicated through a sinking pipe 13. Through the above structural form, a multi-purpose treatment solution can be used to react and absorb the impurities in the nitrogen, improving the purity of the discharged nitrogen.

[0040] As Figure 1 shown in the figure, an inlet pipe 51 is hermetically connected to the front end of the condensation box 2, and an outlet pipe 52 is hermetically connected to the rear end of the drying box 3. Among them, a humidity sensor 6 is arranged inside the outlet pipe 52. Through the above structural form, the humidity sensor 6 can monitor the water content in the discharged nitrogen, providing a reference basis for the user to adjust the power of the external chiller and judge whether it is necessary to replace the drying plate 33.

[0041] The working principle and process of the present utility model:

[0042] The nitrogen recovery device is provided with a condensation box 2 and a drying box 3. Among them, the condensation plate 22 in the condensation box 2 can condense most of the moisture in the gas into liquid through low temperature after the gas flows through, greatly reducing the water content in the gas. Subsequently, the gas passes through the drying box 3, and the drying plate 33 arranged therein can further absorb the remaining moisture in the gas, thereby greatly reducing the water content in the outflowing gas and facilitating the normal use of the subsequent nitrogen.

[0043] In addition, the drying plate 33 is inserted into the strip-shaped insertion rail 32. This installation method can quickly complete the replacement of the drying plate 33 when the drying plate 33 absorbs too much moisture and its water absorption performance seriously deteriorates.

[0044] Particularly, a humidity sensor 6 can be used to monitor the water content in the discharged nitrogen, providing a reference basis for the user to adjust the power of the external chiller and determine whether it is necessary to replace the drying plate 33.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
