Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a high-sealing batching and mixing tank. Background Art

[0002] The existing sewage treatment process generally includes pretreatment, sedimentation, biochemical treatment and membrane treatment.

[0003] The purpose of pretreatment is to remove large mass and large volume debris in sewage using equipment such as screen cleaners; the purpose of sedimentation is to use a scraper to remove oil stains on the surface of sewage, while waiting for small particles of impurities in the sewage to settle to the bottom of the water; the purpose of biochemical treatment is to use different strains of bacteria (anaerobic bacteria, aerobic bacteria, etc.) to activate and biochemically react the organic matter in sewage, remove the organic matter, and avoid eutrophication after sewage is discharged; the purpose of membrane treatment is to intercept heavy metal ions, salt ions, and bacteria, etc., to ensure that the discharged sewage meets national standards.

[0004] In the biochemical treatment step, anaerobic bacteria need to be put into the anaerobic tank to speed up the hydrolysis and acidification of organic matter in the anaerobic tank, thereby removing most of the organic matter in the sewage and providing certain convenient conditions for the back-end aerobic treatment.

[0005] In the prior art, there are two ways to add anaerobic bacteria. One is to place the anaerobic bacteria feeder at the water inlet and adjust the feeding speed so that it is sent into the anaerobic tank together with the sewage.

DETAILED DESCRIPTION

[0029] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0030] Embodiment 1:

[0031] like Figure 1-6 As shown, a high-sealing batching mixing tank includes an outer chamber 1 and an inner chamber 2. The outer chamber 1 is used to activate anaerobic bacteria, and the inner chamber 2 is used to mix the anaerobic bacteria with nutrient solution to facilitate rapid proliferation of the anaerobic bacteria after activation.

[0032] In order to facilitate the delivery of the prepared liquid to be activated in the inner warehouse body 2 to the outer warehouse body 1 for activation, the outer warehouse body 1 is arranged around the inner warehouse body 2.

[0033] In this embodiment, the inner chamber 2 includes a first cavity 21 and a second cavity 22, wherein the first cavity 21 is arranged around the second cavity 22, and the first cavity 21 is rotatably connected to the outer chamber 1. The inner chamber 2 in this embodiment rotates itself driven by the power mechanism, so that the unactivated anaerobic bacteria and nutrient solution entering the inner chamber 2 can be mixed with each other to prepare the liquid to be activated.

[0034] In this solution, the anaerobic bacteria are mixed with the nutrient solution before being sent to the outer bin 1 for activation. In order to reduce the probability of anaerobic bacteria being activated in the inner bin 2, we need to cool the inner bin 2 to keep its internal temperature below 10°C as much as possible. To this end, this solution introduces a cooling plate 23 to cool the inner bin 2. A number of refrigeration fins 23 are installed on the outer wall of the second cavity 22, and a feed pipe 28 is arranged in the second cavity 22. The length direction of the feed pipe 28 is the same as the length direction of the second cavity 22, and the end of the feed pipe 28 away from the bottom of the second cavity 22 is rotatably connected to a feed head 29, and the feed head 29 is connected to a feeding pipe 210, and a number of support arms 211 are arranged between the feed pipe 28 and the inner wall of the second cavity 22; the refrigeration fin 23 includes a low-temperature surface 25 and a high-temperature surface 26, and the low-temperature surface 25 is thermally connected to the outer wall of the second cavity 22, and a heat-conducting column 24 is arranged on the high-temperature surface 26, and a part of the heat-conducting column 24 is located between the outer warehouse body 1 and the first cavity 21.

[0035] The cooling plate 23 in this scheme is a semiconductor cooling plate 23, and its working principle is: when a current passes through a thermocouple pair formed by connecting a piece of N-type semiconductor material and a piece of P-type semiconductor material, heat transfer will occur between the two ends, and the heat will be transferred from one end to the other end, thereby generating a temperature difference to form a cold and hot end. However, the semiconductor itself has resistance. When current passes through the semiconductor, heat will be generated, which will affect heat transfer. In addition, the heat between the two plates will also be reversely transferred through the air and the semiconductor material itself. When the cold and hot ends reach a certain temperature difference and the amount of these two heat transfers is equal, an equilibrium point will be reached, and the positive and reverse heat transfers will cancel each other out. At this time, the temperature of the cold and hot ends will not continue to change. In order to achieve a lower temperature, the temperature of the hot end can be reduced by heat dissipation or other methods.

[0036] Using the above principle, the low temperature surface 25 is connected to the inner warehouse body 2 through heat conduction. At this time, the low temperature surface 25 will transfer the heat of the inner warehouse body 2 to the high temperature surface 26, thus realizing the refrigeration of the inner warehouse body 2. In order to ensure the refrigeration efficiency of the low temperature surface 25, we need to dissipate the heat of the high temperature surface 26. At this time, the heat conducting column 24 is used to transfer the heat on the high temperature surface 26 to the outer warehouse body 1. Anaerobic bacteria require a suitable temperature to be activated, and the activation temperature is generally above 15°C. Therefore, the high temperature surface 26 will preheat the liquid in the outer warehouse body 1 to a certain extent, reducing the overall energy consumption.

[0037] Since a portion of the heat-conducting column 24 is located in the outer chamber 1 , when the solution in the outer chamber 1 submerges the heat-conducting column 24 , the heat-conducting column 24 rotating with the inner chamber 2 will act as a stirring rod to stir the solution in the outer chamber 1 .

[0038] In order to facilitate the delivery of anaerobic bacteria and nutrient solution to the inner warehouse body 2, the present solution introduces a feed pipe 28. The feed pipe 28 is connected to the top of the inner warehouse body 2, and the axis of the feed pipe 28 coincides with the rotation axis of the inner warehouse body 2. In order to facilitate the support of the feed pipe 28, a support arm 211 is provided between the feed pipe 28 and the inner warehouse body 2. In the present solution, the feed pipe 28 rotates with the inner warehouse body 2. In order to facilitate the rotating feed pipe 28 to receive materials such as anaerobic bacteria and nutrient solution, a feed head 29 is provided at one end of the feed pipe 28 away from the bottom of the inner warehouse body 2, and the feed head 29 is rotatably connected to the feed pipe 28. The feed head 29 plays a role of transfer, which transfers various materials in the feeding pipeline 210 to the feed pipe 28.

[0039] The anaerobic bacteria and nutrient solution in this solution can enter the feeding pipe 210 at the same time or separately.

[0040] The anaerobic bacteria used in this scheme are prepared bacterial liquid.

[0041] The heat dissipation efficiency of the outer warehouse body 1 to the high temperature surface 26 is relatively low. In order to improve the heat dissipation efficiency of the high temperature surface 26, an air inlet pipe 212 is installed in the feed pipe 28. The axis of the air inlet pipe 212 coincides with the axis of the feed pipe 28. The end of the air inlet pipe 212 away from the bottom of the second cavity 22 is rotatably connected to the air delivery head 213. The air delivery head 213 is connected to the air delivery pipeline 214. The feed head 29 is rotatably connected to the air inlet pipe 212, and one end of the feed pipeline 210 is connected to the side wall of the feed head 29. The feed head 29 is located between the air delivery head 213 and the feed pipe 28, and the air inlet pipe 212 is sleeved inside the feed pipe 28. In order to prevent the feed head 29 from hindering the air inlet pipe 212 from rotating with the feed pipe 28, the air inlet pipe 212 passes through the feed head 29 and is rotatably connected to the feed head. At the same time, the side wall of the air inlet pipe 212 is rotatably connected to the feed head 29.

[0042] The feed head 29 in this solution includes a feed cavity 215, and the feed pipe 210 transports the material to the feed cavity 215. One end of the feed pipe 28 is connected to the feed cavity 215. There is a gap between the feed pipe 28 and the air inlet pipe 212. At this time, the material in the feed cavity 215 can pass through the gap and enter the second cavity 22 to complete the feeding work. In order to avoid leakage, the air inlet pipe 212 is not only rotatably connected to the feed head 29, but also has a sealing ring 216 between the feed head 29 to play a role of sealing connection.

[0043] In the above scheme, the low-temperature inert gas from the outside reaches the second cavity 22 through the gas delivery pipe 214, the gas delivery head 213 and the air inlet pipe 212. While cooling the material in the second cavity 22, we also need the low-temperature inert gas to cool the high-temperature surface 26. To this end, a number of secondary arms 217 are arranged between the air inlet pipe 212 and the second cavity 22. The secondary arms 217 are hollow, one end of the secondary arms 217 is connected to the air inlet pipe 212, and the other end of the secondary arms 217 is connected to the outer wall of the second cavity 22. The low-temperature gas reaches between the first cavity 21 and the second cavity 22 from the air inlet pipe 212 along the secondary arms 217. Since the low-temperature surface 25 is connected to the outer wall of the second cavity 22 by heat conduction, the high-temperature surface 26 will face the inner wall of the first cavity 21. At this time, the flowing low-temperature gas will pass through the high-temperature surface 26 and the heat-conducting column 24, and take away the heat from both, so as to achieve the cooling work.

[0044] In order to facilitate the flow of low-temperature gas, an air outlet 218 is provided on the outer wall of the first cavity 21, and an air outlet 219 is provided on the top of the outer warehouse body 1. The low-temperature gas exchanges heat with the heat-conducting column 24 and is converted into high-temperature gas. The high-temperature gas enters the outer warehouse body 1 through the air outlet 218 and is then sent to the outside through the air outlet 219 of the outer warehouse body 1. In this process, the high-temperature gas entering the outer warehouse body 1 will exchange heat with the outer warehouse body 1 to a certain extent, and preheating is performed to activate anaerobic bacteria.

[0045] In order to ensure the heat dissipation efficiency of the high temperature surface 26 , the heat conducting column 24 is a U-shaped heat pipe.

[0046] Preferably, a plurality of heat sink fins 27 are connected to the U-shaped heat pipe, a portion of the heat sink fins 27 are located between the first cavity 21 and the second cavity 22, and another portion of the heat sink fins 27 are located between the first cavity 21 and the outer compartment 1. The heat sink fins 27 increase the heat dissipation area of ​​the U-shaped heat pipe, thereby accelerating the heat dissipation efficiency of the U-shaped heat pipe. At the same time, the heat sink fins 27 located in the outer compartment 1 will also rotate with the inner compartment 2. When the solution in the outer compartment 1 submerges the heat sink fins 27, the heat sink fins 27 will also stir the solution, and the heat on the heat sink fins 27 will also be transferred to the solution, accelerating the temperature rise of the solution, thereby accelerating the activation of anaerobic bacteria.

[0047] In order to facilitate the material in the feed pipe 28 to enter the second cavity 22, a plurality of bulk material openings 220 are provided on the side wall of the feed pipe 28, and the plurality of bulk material openings 220 are located inside the second cavity 22. A material distribution platform 221 is provided between the air inlet pipe 212 and the feed pipe 28, and the material distribution platform 221 is conical, and the bottom of the bulk material openings 220 is connected to the bottom of the material distribution platform 221. The conical material distribution platform 221 includes an upper bottom surface with a smaller area and a lower bottom surface with a larger area, and the upper bottom surface faces the feed head 29. At this time, the material falling from the feed pipe 28 will be blocked by the material distribution platform 221, and the blocked material will be evenly sent to the second cavity 22 through bulk material. Since the feed pipe 28 rotates with the inner bin body 2, the material will be evenly scattered around by the bulk material openings 220, increasing the distribution area, thereby accelerating the mixing speed of the anaerobic bacteria and the nutrient solution.

[0048] In this scheme, the mixed liquid to be activated will be initially mixed with sewage in a certain proportion. During the mixing process, the anaerobic bacteria in the mixed liquid will be gradually activated and begin to multiply. In the continuous mixing, the anaerobic bacteria are evenly distributed in the mixed liquid composed of nutrient solution and sewage. This design reduces the amount of anaerobic bacteria put in, and the pre-activated anaerobic bacteria can start working immediately after being sent to the anaerobic tank, reducing the time of intermediate activation and speeding up the working efficiency of the anaerobic tank. In addition, the design does not introduce additional external air, which reduces the oxygen content in the sewage and provides a comfortable environment for the work of anaerobic bacteria.

[0049] In order to facilitate the introduction of sewage into the outer warehouse body 1, an annular water pipe 222 is installed in the outer warehouse body 1. The annular water pipe 222 is arranged around the first cavity 21. The annular water pipe 222 is provided with a plurality of water outlets 223 on the side facing the first cavity 21, and a water inlet pipe 224 is connected to one side of the annular water pipe 222. The refrigeration fins 23 in this scheme are distributed along the length direction of the inner warehouse body 2. At this time, when the water outlets 223 deliver water to the outer warehouse body 1, since the water outlets 223 face the first cavity 21, the sewage will spray toward the heat sink fins 27. At this time, the sewage will cool down the heat sink fins 27. In contrast, the heat sink fins 27 preheat the sewage. Therefore, this design not only speeds up the heat dissipation efficiency of the refrigeration fins 23, but also speeds up the activation speed of anaerobic bacteria.

[0050] Embodiment 2:

[0051] In Example 1, when the solution in the outer chamber 1 submerges a portion of the inner chamber 2, the rotating inner chamber 2 stirs the solution, causing the sewage and the mixed solution to be activated to further mix. However, when the water level of the solution in the outer chamber 1 does not reach the height of the inner chamber 2, the inner chamber 2 cannot stir the solution. Figure 7As shown, the bottom of the inner warehouse body 2 is provided with a discharge port 225, and the discharge port 225 is connected to a stirring column 226, and the stirring column 226 includes a hollow section 227 and a stirring section 228, one end of the hollow section 227 is connected to the discharge port 225, and the other end of the hollow section 227 is connected to the stirring section 228, and a plurality of liquid outlets 229 are provided on the side wall of the hollow section 227, and a plurality of stirring blades 230 are installed on the side wall of the stirring section 228. The discharge port 225 delivers the material in the inner warehouse body 2 to the outer warehouse body 1 through the liquid outlet 229 on the hollow section 227. In this process, the inner warehouse body 2 drives the stirring section 228 and the stirring blades 230 to rotate, stirs the solution in the outer warehouse body 1, and accelerates the mixing of various materials.

[0052] In the above design, when the water line of the solution in the outer warehouse body 1 does not reach the height of the liquid outlet 229, the material in the inner warehouse body 2 can flow normally to the outer warehouse body 1 under the influence of gravity. When the solution submerges the liquid outlet 229, the material in the inner warehouse body 2 will be difficult to fall. In order to avoid this problem, an adapter 231 is installed on the outer wall of the hollow section 227, and the hollow section 227 is rotatably connected to the adapter 231. The adapter 231 includes a receiving cavity 232, and the receiving cavity 232 is arranged around the liquid outlet 229. The side wall of the adapter 231 is connected to a transfer pipe 233, and the end of the transfer pipe 233 away from the adapter 231 is connected to a feed pump 234, and a transfer pipeline 235 is arranged between the feed pump 234 and the annular water pipe 222. The adapter 231 will not rotate with the inner warehouse body 2. Driven by the feeding pump 234 , the material in the inner bin body 2 will first reach the receiving chamber 232 of the adapter 231 , then enter the transfer tube 233 through the receiving chamber 232 , and finally enter the transfer pipeline 235 through the transfer tube 233 , and be sent to the annular water pipe 222 along the transfer pipeline 235 .

[0053] Since the material in the inner warehouse body 2 is in a low temperature state, when the annular water pipe 222 delivers the low temperature material to the outer warehouse body 1 , the low temperature material will cool down the heat dissipation fins 27 , thereby accelerating the heat dissipation of the refrigeration plate 23 .

[0054] Embodiment 3:

[0055] like Figure 1-2 As shown, in order to facilitate the rotation of the inner warehouse body 2, a power motor 3 is installed on the side wall of the outer warehouse body 1, and a sealing cover 31 is provided on the top of the inner warehouse body 2, and the sealing cover 31 is connected to the power motor 3 by a belt.

[0056] Preferably, a sealing platform 32 is provided on the top of the outer warehouse body 1, and a clamping platform 33 is provided on the top of the inner warehouse body 2. The outer diameter of the clamping platform 33 is smaller than the outer diameter of the sealing cover 31. The sealing platform 32 is arranged around the clamping platform 33, and the sealing cover 31 and the clamping platform 33 are both rotatably connected to the sealing platform 32.

[0057] In order to ensure that when the inner warehouse body 2 rotates, it is difficult for outside air to enter the outer warehouse body 1 through the gap between the outer warehouse body 1 and the inner warehouse body 2. A sealing gasket is arranged between the clamping platform 33 and the sealing platform 32. An elastic sealing ring is arranged between the sealing cover 31 and the sealing platform 32.

[0058] Since the ambient temperature is low in winter, the temperature in the outer warehouse body 1 will be affected by the outside world and become low, and it will be difficult for anaerobic bacteria to be activated. Therefore, the outer warehouse body 1 includes a jacket, and a medium pipeline is arranged in the jacket. The medium pipeline is arranged around the outer warehouse body 1, and the medium pipeline is used to transport high-temperature medium, which ensures that the temperature inside the outer warehouse body 1 can be at a suitable temperature for anaerobic bacteria activation.

[0059] Since the content and composition of organic matter in sewage are not fixed, this leads to the problem of low content of a certain element in sewage, which will also affect the working efficiency of anaerobic bacteria. For this reason, this scheme introduces a nutrient solution, which is formulated according to the proportion of each element in sewage, with the aim of supplementing the missing elements in sewage and ensuring the working efficiency of anaerobic bacteria. Due to the high concentration of the nutrient solution, if anaerobic bacteria are activated in the inner warehouse 2, it will make it difficult for anaerobic bacteria to survive. For this reason, we need to dilute the nutrient solution with sewage in the outer warehouse 1, and then activate the anaerobic bacteria to ensure the survival rate of the anaerobic bacteria after activation.

[0060] In summary, the advantages of this solution are: first, by combining the outer warehouse body 1 with the inner warehouse body 2, the anaerobic bacteria are pre-activated, and the anaerobic bacteria can proliferate in advance after the activation is completed, which not only reduces the amount of anaerobic bacteria, but also speeds up the working efficiency of the anaerobic tank. Second, under the action of the refrigeration plate 23, the heat is transferred from the inner warehouse body 2 to the outer warehouse body 1, which keeps the inner warehouse body 2 in a low temperature state, and at the same time can preheat the outer warehouse body 1, reducing energy consumption and speeding up the activation of anaerobic bacteria.

[0061] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
