Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a buried CAST process wastewater treatment equipment. Background Technology

[0002] The shift from large-scale centralized to small- and medium-scale decentralized wastewater treatment systems, forming a layout of "large-scale as the mainstay, with small and medium-sized systems complementing each other," aligns with my country's national conditions and development trends. This provides a new opportunity for the application and development of integrated wastewater treatment equipment. Integrated equipment has been widely used in the treatment of domestic sewage and wastewater from hospitals, beer plants, food processing plants, breweries, and other industries, becoming a research and application hotspot in wastewater treatment equipment in recent years.

[0003] A patent with publication number CN112225313B discloses an underground integrated sewage treatment device, including an equalization tank, an emergency tank on one outer surface of the equalization tank, an SBR tank on one outer surface of the emergency tank, a membrane tank on one outer surface of the SBR tank, a clear water tank on one outer surface of the membrane tank, a sludge tank on one outer surface of the clear water tank, and an equipment room on one outer surface of the sludge tank. A lift pump is installed outside the equalization tank and the SBR tank. By employing the SBR+MBR sewage treatment process, a combination of biochemical and physicochemical methods, it utilizes the physiological activities of different microorganisms to degrade organic matter in the water. Then, through sedimentation, adsorption, and filtration, the effluent quality is improved. It integrates the removal of multiple pollutants such as COD and ammonia nitrogen, combining sedimentation, facultative and aerobic biochemical treatment, and filtration into one sewage treatment process. It is currently a highly efficient sewage treatment device and an ideal choice for small-scale sewage treatment equipment.

[0004] In existing underground sewage treatment equipment, harmful substances and microorganisms in the sewage ferment inside the treatment tank during sewage treatment. This fermentation produces a large amount of waste gas, which increases the air pressure inside the treatment tank. As a result, when the sewage is discharged after purification, the internal air pressure accelerates the discharge, creating a great impact force that pushes the microorganisms inside the sewage into the air, causing pollution. There is no way to periodically release the air pressure inside the sewage treatment tank.

[0005] Therefore, a buried CAST process wastewater treatment equipment is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a buried CAST process wastewater treatment equipment is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The buried CAST process sewage treatment equipment of this utility model includes a snap-fit ​​support arm, an I-shaped exhaust pipe is provided on the top surface of the snap-fit ​​support arm, a water vapor filter cotton is fixedly connected to the inner wall of the I-shaped exhaust pipe, a small motor is fixedly installed on the inner wall of the I-shaped exhaust pipe; an exhaust pipe is provided on one end of the I-shaped exhaust pipe, a sewage treatment tank is fixedly connected to one end of the exhaust pipe, and a snap-fit ​​limiting plate is movably sleeved on the bottom surface of the snap-fit ​​support arm.

[0008] Preferably, a circulating water pipe is fixedly connected to one end of the sewage treatment tank, and a protective sealing cover is provided on the bottom surface of the sewage treatment tank.

[0011] Preferably, an anti-sway base is provided on the bottom surface of the protective sealing cover, and the outer surface of the protective docking cover is movably sleeved on the outer surface of the exhaust pipe.

[0012] Preferably, an arc-shaped plate is fixedly connected to one edge of the top side of the snap-fit ​​support arm, the inner wall of the arc-shaped plate is movably overlapped with the outer surface of the I-shaped exhaust pipe, and a fitting sealing arc plate is provided at the top of the snap-fit ​​support arm, the inner wall of the fitting sealing arc plate is movably sleeved on the I-shaped exhaust pipe and the outer surface of the exhaust pipe.

[0013] Preferably, a snap-fit ​​limiting strip is provided on the outer surface of the sealing arc plate, a transmission rod is movably sleeved on the bottom inner wall of the I-shaped exhaust pipe, and stirring scrapers that are movably sleeved on the inner wall of the I-shaped exhaust pipe are fixedly connected to the outer surfaces of both ends of the transmission rod.

[0014] Preferably, a spacer sealing plate is fixedly connected to the inner side wall of the top of the I-shaped exhaust pipe, and a transmission track is movably sleeved on the outer surface of the output end of the small motor, with the other end of the transmission track movably sleeved on the outer surface of one end of the transmission rod.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a buried CAST process sewage treatment equipment. The snap-fit ​​support arm is connected to the inner wall of the snap-fit ​​limiting plate. At this time, the I-shaped exhaust pipe is connected to the exhaust pipe. With the original air pressure inside the sewage treatment tank, the exhaust gas is effectively discharged through the I-shaped exhaust pipe. The exhaust gas moves unidirectionally through the water source at the bottom of the I-shaped exhaust pipe. The water vapor filter cotton blocks the flowing gas and slowly seeps out, which reduces the gas emission speed. At the same time, the water source inside the I-shaped exhaust pipe can effectively prevent the outside air from being re-injected into the sewage treatment tank through the I-shaped exhaust pipe.

[0017] This utility model provides a buried CAST process sewage treatment equipment. When the small motor rotates, it drives the transmission track and transmission rod to rotate and move together. When the transmission rod rotates, it drives the stirring scraper on the outer surface to rotate inside the I-shaped exhaust pipe. When the stirring scraper rotates inside the I-shaped exhaust pipe, it will stir the water inside the I-shaped exhaust pipe. On the one hand, while stirring the water, it will scrape off some of the sludge adhering to the inner wall of the I-shaped exhaust pipe. After disassembling and attaching the support arm, it will be convenient to rinse and clean the sludge and impurities. On the other hand, while stirring the water, it will also stir and diffuse the heat source left inside, and cool the water.

[0018] This utility model provides a buried CAST process sewage treatment equipment. When the air pressure inside the sewage treatment tank is insufficient, a small motor is used to rotate, causing the gas inside the I-shaped exhaust pipe to move in one direction. The flow of gas will draw the residual waste gas inside the sewage treatment tank and pump the waste gas into the I-shaped exhaust pipe through the exhaust pipe, thereby reducing the air pressure inside the sewage treatment tank. At the same time, the heat generated during the fermentation of sewage inside the sewage treatment tank is discharged, reducing the temperature inside the sewage treatment tank.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Specific implementation examples are given below.

[0030] Please see Figures 1-7 This utility model provides a buried CAST process sewage treatment equipment, including a snap-fit ​​support arm 13, an I-shaped exhaust pipe 133 is provided on the top surface of the snap-fit ​​support arm 13, a water vapor filter cotton 135 is fixedly connected to the inner wall of the I-shaped exhaust pipe 133, a small motor 139 is fixedly installed on the inner wall of the I-shaped exhaust pipe 133; an exhaust pipe 125 is provided on one end of the I-shaped exhaust pipe 133, a sewage treatment tank 123 is fixedly connected to one end of the exhaust pipe 125, and a snap-fit ​​limiting plate 126 is movably sleeved on the bottom surface of the snap-fit ​​support arm 13;

[0031] During operation, the snap-fit ​​support arm 13 is connected to the inner wall of the snap-fit ​​limiting plate 126. At this time, the I-shaped exhaust pipe 133 is connected to the exhaust pipe 125. With the original air pressure inside the sewage treatment tank 123, the exhaust gas is effectively discharged through the I-shaped exhaust pipe 133 and moves unidirectionally through the water source at the bottom of the I-shaped exhaust pipe 133. The water vapor filter cotton 135 blocks the flowing gas and slowly permeates out, so that the exhaust gas emission speed can be reduced. At the same time, the water source inside the I-shaped exhaust pipe 133 can effectively prevent the outside air from being re-injected into the sewage treatment tank 123 through the I-shaped exhaust pipe 133.

[0032] When the air pressure inside the sewage treatment tank 123 is insufficient, the small motor 139 rotates, causing the gas inside the I-shaped exhaust pipe 133 to move in one direction. The flow of gas will draw the residual waste gas inside the sewage treatment tank 123 and pump the waste gas into the I-shaped exhaust pipe 133 through the exhaust pipe 125, thereby reducing the air pressure inside the sewage treatment tank 123. At the same time, the heat generated during the fermentation of sewage inside the sewage treatment tank 123 will be discharged, reducing the internal temperature of the sewage treatment tank 123.

[0033] Furthermore, such as Figures 1-3 and Figures 4 to 7 As shown, an arc-shaped plate is fixedly connected to one edge of the top of the snap-fit ​​support arm 13. The inner wall of the arc-shaped plate movably overlaps the outer surface of the I-shaped exhaust pipe 133. A fitting and sealing arc plate 131 is provided at the top of the snap-fit ​​support arm 13. The inner wall of the fitting and sealing arc plate 131 movably fits onto the outer surface of the I-shaped exhaust pipe 133 and the exhaust pipe 125. A snap-fit ​​limiting strip 132 is provided on the outer surface of the fitting and sealing arc plate 131. The I-shaped exhaust pipe 13... A transmission rod 136 is movably sleeved on the bottom inner wall of the 3. A stirring scraper 137 is fixedly connected to the outer surfaces of both ends of the transmission rod 136 and is movably sleeved on the inner wall of the I-shaped exhaust pipe 133. A spacer sealing plate 134 is fixedly connected to the top inner wall of the I-shaped exhaust pipe 133. A transmission track 138 is movably sleeved on the outer surface of the output end of the small motor 139. The other end of the transmission track 138 is movably sleeved on the outer surface of one end of the transmission rod 136.

[0034] During operation, when the small motor 139 rotates, it drives the transmission track 138 and the transmission rod 136 to rotate and move together. When the transmission rod 136 rotates, it drives the stirring scraper 137 on the outer surface to rotate inside the I-shaped exhaust pipe 133. When the stirring scraper 137 rotates inside the I-shaped exhaust pipe 133, it stirs the water inside the I-shaped exhaust pipe 133. On the one hand, while stirring the water, it scrapes off some of the sludge adhering to the inner wall of the I-shaped exhaust pipe 133, making it easier to rinse and clean the sludge and impurities after the support arm 13 is disassembled and attached. On the other hand, while stirring the water, it also stirs and diffuses the heat source left inside, and cools the water.

[0035] Furthermore, such as Figures 1 to 4 As shown, a circulating water pipe 124 is fixedly connected to one end of the sewage treatment tank 123. A protective sealing cover 12 is provided on the bottom surface of the sewage treatment tank 123. Spacer support plates 121 are provided on the inner walls of both sides of the protective sealing cover 12. A docking cavity is provided between the spacer support plates 121 and the protective sealing cover 12. A protective docking cover 122 is movably sleeved on the inner wall of the docking cavity. One side surface of the snap-fit ​​limiting plate 126 is fixedly connected to one side surface of the protective sealing cover 12. An anti-sway base platform 11 is provided on the bottom surface of the protective sealing cover 12. The outer side surface of the protective docking cover 122 is movably sleeved on the outer side surface of the exhaust pipe 125.

[0036] During operation, the anti-sway foundation 11 is laid flat inside the deep pit. After the pit is secured, the protective sealing cover 12 is attached to the top surface of the anti-sway foundation 11. The sewage treatment tank 123 and the circulating water pipe 124 are then installed inside the protective sealing cover 12. Later, the gaps around the protective sealing cover 12 are filled with soil to further define its position. Then, the protective docking cover 122 is fitted into the gap between the spacer support plate 121 and the protective sealing cover 12. This avoids contact force between the outer surface of the protective docking cover 122 and the soil, allowing the protective docking cover 122 to be quickly removed from inside the protective sealing cover 12 for easy maintenance of the sewage treatment tank 123 inside the protective sealing cover 12.

[0037] Working principle: The snap-fit ​​support arm 13 is connected to the inner wall of the snap-fit ​​limiting plate 126. At this time, the I-shaped exhaust pipe 133 is connected with the exhaust pipe 125. With the original air pressure inside the sewage treatment tank 123, the exhaust gas is effectively discharged through the I-shaped exhaust pipe 133. The exhaust gas moves unidirectionally through the water source at the bottom of the I-shaped exhaust pipe 133 and is blocked and slowly permeated through the water vapor filter cotton 135. This reduces the exhaust gas emission speed. At the same time, the water source inside the I-shaped exhaust pipe 133 can effectively prevent outside air from being re-injected into the sewage treatment tank 123 through the I-shaped exhaust pipe 133.

[0038] When the air pressure inside the sewage treatment tank 123 is insufficient, the small motor 139 rotates, causing the gas inside the I-shaped exhaust pipe 133 to move in one direction. The flow of gas will draw the residual waste gas inside the sewage treatment tank 123 and pump the waste gas into the I-shaped exhaust pipe 133 through the exhaust pipe 125, thereby reducing the air pressure inside the sewage treatment tank 123. At the same time, the heat generated during the fermentation of sewage inside the sewage treatment tank 123 will be discharged, reducing the internal temperature of the sewage treatment tank 123.

[0039] When the small motor 139 rotates, it drives the transmission track 138 and the transmission rod 136 to rotate and move together. When the transmission rod 136 rotates, it drives the stirring scraper 137 on the outer surface to rotate inside the I-shaped exhaust pipe 133. When the stirring scraper 137 rotates inside the I-shaped exhaust pipe 133, it stirs the water inside the I-shaped exhaust pipe 133. On the one hand, while stirring the water, it scrapes off some of the sludge adhering to the inner wall of the I-shaped exhaust pipe 133, making it easier to rinse and clean the sludge and impurities after the support arm 13 is disassembled and attached. On the other hand, while stirring the water, it also stirs and diffuses the heat source left inside and cools the water.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
