Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium hypochlorite production technology, and more specifically, to a recycling device for calcium hypochlorite production. Background Technology
[0002] Calcium hypochlorite is an inorganic compound commonly used in the bleaching process in chemical production. Aqueous solutions of calcium hypochlorite have a bleaching effect and can decolorize colored substances. This is because the hypochlorous acid generated by calcium hypochlorite in water has strong oxidizing properties and can destroy the color-forming structure of colored substances. Due to its rapid onset of action and outstanding bleaching effect, it plays an important role in industrial production.
[0003] Existing calcium hypochlorite production facilities release excess chlorine gas during the production process, and this excess chlorine gas cannot be recycled. The released chlorine gas not only pollutes the environment but also affects the health of production personnel. Chlorine gas mainly enters the human body through the respiratory tract and dissolves in the moisture contained in the mucous membranes, generating hypochlorous acid and hydrochloric acid, which damage the upper respiratory tract mucosa.
[0004] A search revealed that Chinese patent CN210595259U discloses a waste gas recycling device for calcium hypochlorite production. This device starts a motor inside the motor housing, which drives the stirring blades to mix quicklime and water inside the mixing tank. Chlorine gas is then introduced into the mixing tank through a second inlet pipe for mixing and reaction. After sufficient reaction, calcium hypochlorite is obtained. The tank door is opened to remove the calcium hypochlorite. The stirring process generates heat, which cools the mixing tank. Excess chlorine gas inside the mixing tank is pumped through a first inlet pipe to a storage tank. Dust in the chlorine gas is filtered out by a filter box, and the second valve is closed. When chlorine gas is needed again, the third valve is opened for reuse. This device recovers, filters, and stores excess chlorine gas, recycling it and increasing safety.
[0005] However, in actual use, excess exhaust gas inside the mixing tank enters the gas storage tank, and then the dust in the exhaust gas is filtered through the filter box, but harmful substances in the exhaust gas still remain, which affects the absorption and filtration efficiency.

[0009] The recycling mechanism includes a collection box fixedly installed on one side of a conveying pipe. One end of the conveying pipe passes through the collection box and extends into the collection box. A sealing pipe is snapped onto the outside of the collection box. A filter frame is fixedly installed on one side of the sealing pipe. Multiple filter screens are fixedly installed on the surface of the filter frame. A support frame is fixedly installed at the bottom of the filter frame. A slot is opened on the surface of the filter frame. A sealing plate is snapped into the inside of the slot. A stabilizing frame is fixedly installed inside the collection box. The stabilizing frame is located at the bottom of the support frame. A filter plate is snapped into the inside of the stabilizing frame. A connecting pipe is provided through the bottom of the collection box. A circulating air pump is fixedly installed on one side of the connecting pipe.
[0010] By adopting the above technical solution, the amount of harmful waste gas emitted into the atmosphere is greatly reduced, thus mitigating environmental pollution and facilitating the recycling of waste gas.
[0011] As a further description of the above technical solution: a collection box door is hinged to one side of the collection box, and multiple support legs are fixedly installed at the bottom of the collection box. The bottoms of the multiple support legs are all fixedly connected to the support frame. A processing box door is hinged to the top of the processing box door, and a feeding hopper is provided through the top of the processing box door. A fixed cover is threadedly connected to the inside of the feeding hopper.
[0012] By adopting the above technical solution, the material feeding is facilitated, the overall stability is enhanced, and the overall performance is improved.
[0013] As a further description of the above technical solution: a circulation mechanism is fixedly installed on one side of the working box. The circulation mechanism includes a water inlet pipe fixedly installed on the top of the working box, a circulation pipe fixedly installed on the bottom of the working box, the cross-section of the circulation pipe being U-shaped, a water stop valve fixedly installed on one side of the circulation pipe, a heat dissipation box fixedly installed on the top of the support frame, one end of the circulation pipe penetrating the heat dissipation box and extending to the outside of the heat dissipation box, and a circulating water pump fixedly installed on one side of the circulation pipe.
[0014] By adopting the above technical solution, rapid cooling through water circulation is achieved, thereby improving work efficiency.
[0015] As a further description of the above technical solution: a box is fixedly installed on the top of the heat dissipation box, and multiple heat dissipation holes are opened on the surface of the box. A motor is fixedly installed inside the box, and a rotating shaft is fixedly installed at the output end of the motor. One end of the rotating shaft passes through the working box and the processing box in sequence and extends into the processing box. An inclined plate is rotatably connected to one end of the rotating shaft. Both ends of the inclined plate are connected to the inner wall of the processing box. Multiple stirring blades are fixedly installed outside the rotating shaft.

[0016] By adopting the above technical solution, in order to facilitate stirring, the quicklime and water are fully mixed, thereby accelerating the reaction effect.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] By setting up a recycling mechanism, compared with existing technologies, the exhaust gas inside the treatment box is driven by a circulating air pump through a delivery pipe into the collection box, and then through a sealed pipe into the filter frame. The filter screen on the surface of the filter frame filters out dust, causing the filtered exhaust gas to move outward from the filter screen, removing solid particles. It then comes into contact with lime milk on the top of the filter plate, where the lime milk absorbs chlorine and acidic gases from the exhaust gas, removing harmful substances. The gas is then re-entered into the treatment box through a connecting pipe for secondary use. This saves production resources, prevents the indiscriminate discharge of toxic gases, increases safety, and facilitates the disassembly and cleaning of the filter frame, as well as the addition of material to the filter plate, thereby improving the performance.
[0019] By setting up a circulation mechanism, compared with existing technologies, the processing tank needs to be cooled. Cold water is added between the working tank and the processing tank through a water inlet pipe, so that the cold water comes into contact with the surface of the processing tank and absorbs the heat inside the processing tank. Then, by starting the circulating water pump, the cold water that has absorbed heat inside the working tank is transported through the circulation pipe to the inside of the heat dissipation box. Ice water is added to the inside of the heat dissipation box through an external cold water pipe, thereby cooling the circulation pipe. At the same time, the circulating water pump transports the cooled water inside the circulation pipe to the inside of the working tank to continue cooling the processing tank, thus forming a circulation.

[0026] 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.
[0027] The embodiments disclosed in this application are as follows: Figure 1-5 The shown is a recycling device for calcium hypochlorite production, including a working box 1 set on the top of a support frame, a processing box 2 fixedly set inside the working box 1, the top of the processing box 2 penetrating through the working box 1 and extending to the outside of the working box 1, a conveying pipe 3 penetrating one side of the processing box 2, and a recycling mechanism fixedly set at one end of the conveying pipe 3.
[0028] The recycling mechanism includes a collection box 4 fixedly mounted on one side of a conveying pipe 3. One end of the conveying pipe 3 passes through the collection box 4 and extends into it. A sealing pipe 5 is snapped onto the outside of the collection box 4. A filter frame 6 is fixedly mounted on one side of the sealing pipe 5. Multiple filter screens 7 are fixedly mounted on the surface of the filter frame 6. A support frame 8 is fixedly mounted at the bottom of the filter frame 6. A slot is formed on the surface of the filter frame 6, and a sealing plate 9 is snapped into the slot. A stabilizing frame 10 is fixedly mounted inside the collection box 4, located at the bottom of the support frame 8. A filter plate 11 is snapped into the inside of the stabilizing frame 10. A connecting pipe 12 passes through the bottom of the collection box 4, and a circulating air pump 13 is fixedly mounted on one side of the connecting pipe 12. After the chlorine in treatment box 2 has fully reacted with the quicklime, the waste gas inside treatment box 2 is driven by the start of the circulating air pump 13, which carries the waste gas through the delivery pipe 3 into the collection box 4, and then through the sealing pipe 5 into the filter frame 6. The dust is filtered through the filter screen 7 on the surface of the filter frame 6, causing the filtered waste gas to move out of the filter screen 7, removing solid particles from the waste gas. Then it comes into contact with the lime milk on the top of the filter plate 11, where the lime milk absorbs the acidic chlorine gas in the waste gas, removing harmful substances from the waste gas. The waste gas is then re-entered into the treatment box 2 through the connecting pipe 12 for secondary use, saving production resources, preventing the random discharge of toxic gases, and increasing safety.
[0029] Reference Figure 2-3 As shown, a collection box door is hinged to one side of the collection box 4. Multiple support legs 14 are fixedly installed at the bottom of the collection box 4, and the bottom of the multiple support legs 14 are fixedly connected to the support frame. A processing box door 15 is hinged to the top of the processing box door 15. A feed hopper 16 is provided through the top of the processing box door 15. A fixed cover is threadedly connected inside the feed hopper 16. First, rotate the fixed cover in the forward direction to separate the fixed cover from the feed hopper 16. Then, pour quicklime into the processing box 2. Add an appropriate amount of water into the processing box 2 according to the amount of quicklime poured in. After completion, rotate the fixed cover in the reverse direction to improve the sealing effect.
[0030] Reference Figure 3-4As shown, a circulation mechanism is fixedly installed on one side of the working chamber 1. The circulation mechanism includes a water inlet pipe 17 fixedly installed on the top of the working chamber 1, a circulation pipe 18 fixedly installed on the bottom of the working chamber 1, the circulation pipe 18 having a U-shaped cross-section, a stop valve fixedly installed on one side of the circulation pipe 18, a heat dissipation box 19 fixedly installed on the top of the support frame, one end of the circulation pipe 18 passing through the heat dissipation box 19 and extending outward from the heat dissipation box 19, and a circulating water pump 20 fixedly installed on one side of the circulation pipe 18. During the stirring process, heat is generated, requiring cooling of the processing chamber 2, which is achieved through the water inlet pipe. 17. Cold water is added between the working chamber 1 and the processing chamber 2, so that the cold water comes into contact with the surface of the processing chamber 2, thereby absorbing the heat inside the processing chamber 2. The circulating water pump 20 is started to drive the cold water that has absorbed heat inside the working chamber 1 to the interior of the heat dissipation box 19 through the circulation pipe 18. Ice water is added to the interior of the heat dissipation box 19 through the external cold water pipe, thereby cooling the circulation pipe 18. At the same time, the circulating water pump 20 delivers the cooled water inside the circulation pipe 18 to the interior of the working chamber 1 to continue cooling the processing chamber 2, thus forming a circulation.
[0031] Reference Figure 3-5 As shown, a housing 21 is fixedly mounted on the top of the heat dissipation box 19. Multiple heat dissipation holes are provided on the surface of the housing 21. A motor is fixedly installed inside the housing 21, and a rotating shaft 22 is fixedly mounted on the output end of the motor. One end of the rotating shaft 22 passes through the working chamber 1 and the processing chamber 2 sequentially and extends into the processing chamber 2. An inclined plate 23 is rotatably connected to one end of the rotating shaft 22. Both ends of the inclined plate 23 are connected to the inner wall of the processing chamber 2. Multiple stirring blades 24 are fixedly mounted on the outside of the rotating shaft 22. An air inlet pipe 25 is fixedly mounted on one side of the working chamber 1, and a butterfly valve is fixedly mounted on one side of the air inlet pipe 25. One end of the connecting pipe 12 passes through the working chamber 1 and the processing chamber 2 sequentially and... Extending into the processing chamber 2, the motor inside the housing 21 is started. Since the surface of the housing 21 has multiple heat dissipation holes, it will not affect the normal heat dissipation and operation of the internal motor. Then the motor drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the stirring blade 24 to rotate. Since one end of the rotating shaft 22 is rotatably connected to the inclined plate 23, the stability during the rotation process is improved. Through the rotation of the stirring blade 24, the quicklime and water inside the processing chamber 2 are mixed. After mixing, the butterfly valve on one side of the air inlet pipe 25 is opened, and chlorine gas is delivered into the processing chamber 2 through the air inlet pipe 25 for mixing reaction. After the reaction is complete, calcium hypochlorite will be obtained.
[0032] Working principle of this utility model:
[0033] This utility model is a recycling device for calcium hypochlorite production. When using the device, first rotate the fixed cover forward to separate the fixed cover from the feed hopper 16. Then, pour quicklime into the processing tank 2. Add an appropriate amount of water to the processing tank 2 according to the amount of quicklime poured in. After that, rotate the fixed cover in reverse to close the feed hopper 16. Then, start the motor inside the machine box 21. Since the surface of the machine box 21 has multiple heat dissipation holes, it will not affect the normal heat dissipation and operation of the internal motor. Then, the motor drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the stirring blade 24 to rotate. Since one end of the rotating shaft 22 is rotatably connected to the inclined plate 23, the stability during the rotation process is improved. And through the rotation of the stirring blade 24, the quicklime and water inside the processing tank 2 are mixed. After mixing, open the butterfly valve on one side of the air inlet pipe 25, and chlorine gas is transported into the processing tank 2 through the air inlet pipe 25 for mixing reaction. After the reaction is complete, calcium hypochlorite will be obtained.
[0034] Heat is generated during the stirring process, so the processing tank 2 needs to be cooled down. Cold water is added between the working tank 1 and the processing tank 2 through the water inlet pipe 17, so that the cold water comes into contact with the surface of the processing tank 2 and absorbs the heat inside the processing tank 2. The circulating water pump 20 is started to drive the cold water that has absorbed heat in the working tank 1 to the heat dissipation box 19 through the circulation pipe 18. Ice water is added to the heat dissipation box 19 through the external cold water pipe, thereby cooling the circulation pipe 18. At the same time, the circulating water pump 20 delivers the cooled water in the circulation pipe 18 to the working tank 1 to continue cooling the processing tank 2, thus forming a cycle.
[0035] After the chlorine and quicklime in the treatment box 2 have fully reacted, the waste gas inside the treatment box 2 is driven by the start of the circulating air pump 13, which carries the waste gas through the conveying pipe 3 into the collection box 4, and then through the sealing pipe 5 into the filter frame 6. The dust is filtered by the filter screen 7 on the surface of the filter frame 6, causing the filtered waste gas to move to the outside of the filter screen 7, removing solid particles from the waste gas. Then it comes into contact with the lime milk on the top of the filter plate 11, where the lime milk absorbs the acidic chlorine gas in the waste gas, removing harmful substances from the waste gas. The waste gas is then re-entered into the treatment box 2 through the connecting pipe 12 for secondary use, saving production resources, preventing the random discharge of toxic gases, and increasing safety.
[0036] After a period of use, open the collection box door, then pull the filter frame 6 away from the conveying pipe 3, thereby separating the conveying pipe 3 from the sealing pipe 5, and causing the filter frame 6 to slide on the stabilizing frame 10, thereby removing the filter frame 6. Next, pull the sealing plate 9 upward, thereby moving the sealing plate 9 inside the slot, removing the sealing plate 9, emptying the dust inside the filter frame 6, and cleaning the filter screen 7. Then, pull the filter plate 11 outward, causing the filter plate 11 to separate from the stabilizing frame 10, thereby removing the filter plate 11, and replacing the lime milk inside. The operation is convenient and quick.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
