Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sewage treatment, and particularly relates to a new energy decentralized sewage treatment device. BACKGROUND

[0002] As an important innovation in the environmental protection field, the new energy sewage treatment equipment uses renewable energy such as solar energy and wind energy to provide power for sewage treatment, showing significant environmental protection and energy saving advantages, and effectively reducing the operation cost. This technical trend not only meets the strategic demand of global sustainable development, but also brings new development opportunities to the field of sewage treatment.

[0003] A new energy sewage treatment device is disclosed in the Chinese utility model patent with the authorized announcement number CN118579944A. The device realizes efficient contact between bubbles and water bodies through a unique design of an aeration head and a rotating drum. Specifically, the rotating drum is located directly above the equidistantly arranged aeration heads and is arranged in parallel with the aeration heads, so that the bubbles can contact the circumferential side of the rotating drum after being sprayed and move along the two sides. This design effectively increases the floating path of the bubbles and prolongs the residence time of the bubbles in the water body, thereby significantly improving the sewage treatment efficiency.

[0004] However, although the device has achieved remarkable results in sewage treatment efficiency, in the actual application process, the device needs to additionally install a telescopic rod to push the push-pull piece to reciprocate inside the rotating drum, which not only increases the energy consumption of the equipment, but also fails to fully utilize the rotating energy of the rotating drum.

[0005] Therefore, the application provides a new energy decentralized sewage treatment device to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] The application provides a new energy decentralized sewage treatment device, which aims to solve the problems that the existing sewage treatment device needs to additionally install a telescopic rod to push the push-pull piece to reciprocate inside the rotating drum, which not only increases the energy consumption of the equipment, but also fails to fully utilize the rotating energy of the rotating drum and the like.

[0007] To achieve the above purpose, the application provides the following technical scheme: a new energy decentralized sewage treatment device, comprising a liquid containing drum, an aeration structure arranged at the bottom of the inner cavity of the liquid containing drum, and a stirring structure for prolonging the residence time of gas bubbles.

In the process of moving the bubbles to the two sides of the rotating drum, the push-pull piece moves reciprocatingly in the rotating drum by the reciprocating piece. Since the push-pull piece divides the rotating drum into two cavities, when the push-pull piece moves reciprocatingly, the volume of one cavity gradually increases, and the volume of the other cavity gradually decreases, so that the cavity with gradually increasing volume sucks the bubbles close to the rotating drum through the through hole, and the time of the part of the bubbles staying in the water body is further prolonged, thereby improving the sewage treatment efficiency, and the cavity with gradually decreasing volume pushes the bubbles in the rotating drum out of the through hole, and the flow of the sewage and the bubbles is horizontal or downward, so that the path of the part of the bubbles moving in the sewage is increased, thereby prolonging the time of the bubbles staying in the water body, and at the same time, the part of the ejected sewage contacts the subsequent bubbles moving to the two sides of the rotating drum, thereby driving part of the bubbles to move, so that the distance of part of the bubbles moving to the two sides of the rotating drum is increased, thereby further improving the sewage treatment efficiency.

[0009] Preferably, the rotating drum is arranged at the top of the inner cavity of the liquid container, the rotating shaft is rotatably inserted on the liquid container and is fixedly connected with one end of the rotating drum, and the driving motor is mounted on the liquid container and the output end of the driving motor is fixedly connected with the end of the rotating shaft away from the rotating drum. The rotating drum is arranged at the top of the inner cavity of the liquid container and matches the rising path of the bubbles formed by the aeration structure, so that the time of the bubbles staying in the water body is maximally prolonged, the contact area and the contact time of the bubbles and the sewage are increased, thereby promoting the sufficient contact and oxidation decomposition of the organic matter and the microorganisms and improving the sewage treatment efficiency.

[0010] Preferably, in order to improve the sealing performance of the connection between the rotating shaft and the liquid container, an axial sealing piece is arranged on the rotating shaft to seal the gap between the rotating shaft and the liquid container. The axial sealing piece effectively improves the sealing performance of the connection between the rotating shaft and the liquid container, prevents the leakage of the sewage and the entry of foreign matters into the inside of the device, and ensures the continuity and stability of the sewage treatment process.

[0011] Preferably, in order to facilitate the installation of the driving motor: the liquid container is fixedly connected with a bracket for installing the driving motor, the driving motor is fixedly installed on the bracket through bolts, and the output end of the driving motor is fixedly connected with the end face of the rotating shaft.

The cooperation of the square rod and the square groove makes the installation of the fixing plate more simple and fast.

[0013] Preferably, in order to facilitate the extension of the time for the bubbles discharged from the rotating drum to be discharged from the bottom of the rotating drum and prolong the retention time of the bubbles: a fixed part is arranged above the push-pull part in the interior of the rotating drum, the length of the fixed part is greater than the length of the push-pull part, the length of the fixed part is equal to the length of the inner cavity of the rotating drum, the fixed part forms a sliding contact with the inner wall of the rotating drum, the lower side of the fixed part forms a sliding contact with the upper side of the push-pull part, and the cross section of the fixed part and the cross section of the push-pull part together form a circle.

[0014] Preferably, the aeration structure comprises a communication pipe arranged at the bottom of the inner cavity of the liquid container and a plurality of aeration heads fixedly installed on the communication pipe, wherein the air inlet end of the communication pipe extends to the outside of the liquid container and communicates with the air pump. The aeration structure increases the contact area and contact time of the bubbles and the sewage by injecting micro-bubbles into the sewage, thereby promoting the sufficient contact and oxidative decomposition of the organic matter and the microorganisms.

[0015] Preferably, the outside of the liquid container is provided with a photovoltaic panel for providing electric energy to the driving motor, and the photovoltaic panel is electrically connected with the driving motor.

[0016] The application replaces the traditional telescopic rod driving mode by utilizing the rotation of the rotating drum to drive the reciprocating movement of the push-pull part, thereby reducing the use and energy consumption of the driving part. The reciprocating connection of the reciprocating screw rod and the push-pull part, and the cooperation of the limiting rod and the fixing plate, fully utilize the rotation energy of the rotating drum, thereby improving the utilization rate of the structure.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] The present embodiment provides a new energy decentralized sewage treatment device, as shown in the figure, which comprises a liquid-containing drum 1, an aeration structure 2 arranged at the bottom of the inner cavity of the liquid-containing drum 1, and a stirring structure 3 for prolonging the gas pocket retention time. Figs. 1-3

[0024] ​In order to facilitate the reciprocating movement of the push-pull piece 34 driven by the rotation of the rotating drum 31, the stirring structure 3 comprises the rotating drum 31, the rotating shaft 32, the driving motor 33, the push-pull piece 34 arranged to move axially in the rotating drum 31, and the reciprocating piece 35 for driving the reciprocating movement of the push-pull piece 34, wherein a plurality of through holes 311 are arranged in the rotating drum 31 in an annular array; the reciprocating piece 35 comprises a reciprocating screw rod 351 reciprocally inserted on the push-pull piece 34 and fixedly connected with the shaft rod in the rotating drum 31, a fixed plate 352 inserted on the other end of the rotating drum 31 and connected with the liquid container 1, and a limiting rod 353 inserted on the push-pull piece 34 and fixedly connected with the fixed plate 352. By utilizing the rotation of the rotating drum 31 to drive the reciprocating movement of the push-pull piece 34, the traditional telescopic rod driving mode is replaced, and the use and energy consumption of the driving piece are reduced. The reciprocating connection of the reciprocating screw rod 351 and the push-pull piece 34, and the cooperation of the limiting rod 353 and the fixed plate 352, make full use of the rotational energy of the rotating drum 31, and improve the utilization rate of the structure. By optimizing the contact effect of bubbles and sewage, the residence time of bubbles in the water body is prolonged, the sufficient contact and oxidative decomposition of organic matter and microorganisms are promoted, and thus the sewage treatment efficiency is improved. In use, the sewage is input into the liquid container 1, then the bottom of the liquid container 1 is aerated by the aeration structure 2, and bubbles are formed in the water, then the bubbles float up, so that the oxygen molecules in the bubbles are gradually transferred to the sewage, thereby promoting the contact between the organic matter and the microorganisms in the sewage, realizing the oxidative decomposition of the organic matter, and purifying the sewage. In the above process of bubble floating up, the bubbles sprayed by the aeration structure 2 will contact the circumferential side surface of the rotating drum 31, and then move along the side surface to both sides of the rotating drum 31. Through the above action, the floating path of the bubbles is increased, so that the residence time of the bubbles in the water body is prolonged, and thus the sewage treatment efficiency is improved; in the above process of the bubbles moving to both sides of the rotating drum 31, the push-pull piece 34 is reciprocated in the rotating drum 31 by the reciprocating piece 35. Since the push-pull piece 34 divides the rotating drum 31 into two cavities, when the push-pull piece 34 reciprocates, the volume of one side cavity gradually increases, and the volume of the other side cavity gradually decreases, so that the side cavity with gradually increasing volume sucks the bubbles close to the rotating drum 31 through the through holes 311, so that the residence time of the part of bubbles in the water body is further prolonged, thereby improving the sewage treatment efficiency, while the cavity with gradually decreasing volume pushes the bubbles in the rotating drum 31 and the sewage out of the through holes 311, the flow direction of the sewage and the bubbles is horizontal or downward, so that the path of the part of bubbles in the sewage is increased, thereby prolonging the residence time of the bubbles in the water body, and at the same time, the part of the sprayed sewage will contact the subsequent bubbles moving to both sides of the rotating drum 31, thereby driving part of the bubbles to move, so that the distance of part of the bubbles moving to both sides of the rotating drum 31 is increased, thereby further improving the sewage treatment efficiency.

[0025] Specifically, the rotating drum 31 is arranged at the top of the inner cavity of the liquid container 1, the rotating shaft 32 is rotatably connected to the liquid container 1 and fixedly connected to one end of the rotating drum 31, the driving motor 33 is arranged on the liquid container 1, and the output end of the driving motor 33 is fixedly connected to the end of the rotating shaft 32 away from the rotating drum 31. The rotating drum 31 is arranged at the top of the inner cavity of the liquid container 1 and matches the bubble rising path formed by the aeration structure 2, which can maximize the retention time of the bubbles in the water body, increase the contact area and contact time of the bubbles and the sewage, thereby promoting the sufficient contact and oxidative decomposition of the organic matter and the microorganisms and improving the sewage treatment efficiency.

[0026] Specifically, in order to improve the sealing performance of the connection between the rotating shaft 32 and the liquid container 1, the shaft seal 321 is arranged on the rotating shaft 32 to seal the gap between the rotating shaft 32 and the liquid container 1. The arrangement of the shaft seal 321 effectively improves the sealing performance of the connection between the rotating shaft 32 and the liquid container 1, prevents the leakage of sewage and the entry of foreign matters into the device, and ensures the continuity and stability of the sewage treatment process.

[0027] Specifically, in order to facilitate the installation of the driving motor 33, the bracket 331 for installing the driving motor 33 is fixedly connected to the liquid container 1, the driving motor 33 is fixedly installed on the bracket 331 through bolts, and the output end of the driving motor 33 is fixedly connected to the end face of the rotating shaft 32. The design of the bracket 331 makes the installation of the driving motor 33 more simple and fast. Without complex positioning and fixing operations, the driving motor 33 can be placed on the bracket 331 and fixed by bolts. The bolt connection between the bracket 331 and the driving motor 33 makes the maintenance more convenient. When the driving motor 33 needs to be replaced or repaired, it can be easily removed by detaching the bolts without disassembling the entire device. This greatly reduces the difficulty and cost of maintenance.

[0028] Specifically, in order to facilitate the installation of the fixing plate 352, the square rod 3521 is fixedly connected to the end of the fixing plate 352 away from the rotating drum 31, and the square groove 11 is arranged on the inner wall of the liquid container 1 for inserting the square rod 3521. The matching structure of the square rod 3521 and the square groove 11 makes the installation of the fixing plate 352 more simple and fast. Without complex positioning and fixing operations, the square rod 3521 can be inserted into the square groove 11. This greatly improves the installation efficiency and reduces the installation cost. When the fixing plate 352 needs to be maintained or replaced, the square rod 3521 can be easily pulled out of the square groove 11 without disassembling the entire device. This greatly reduces the difficulty and cost of maintenance.

[0029] Further, in order to facilitate the bubbles discharged from the rotating drum 31 to be discharged from the bottom of the rotating drum 31 and prolong the residence time of the bubbles: the inside of the rotating drum 31 is provided with a fixed part 312 corresponding to the upper side of the push-pull part 34, the length of the fixed part 312 is greater than the length of the push-pull part 34, the length of the fixed part 312 is equal to the length of the inner cavity of the rotating drum 31, the fixed part 312 is in sliding contact with the inner wall of the rotating drum 31, the lower side of the fixed part 312 is in sliding contact with the upper side of the push-pull part 34, and the cross section of the fixed part 312 and the cross section of the push-pull part 34 together form a circle. The fixed part 312 always blocks the through hole 311 on the upper side of the rotating drum 31, so that when the bubbles in the rotating drum 31 and the sewage are sprayed from the through hole 311, the direction of the water flow is at the two sides and the lower side of the rotating drum 31. Through this action, the residence time of the bubbles in the water body is further prolonged.

[0030] Specifically, the aeration structure 2 includes a communication pipe 21 arranged at the bottom of the inner cavity of the liquid container 1 and a plurality of aeration heads 22 fixedly installed on the communication pipe 21, wherein the air inlet end of the communication pipe 21 extends to the outside of the liquid container 1 and is in communication with the air pump. The aeration structure 2 increases the contact area and contact time of the bubbles and the sewage by injecting micro-bubbles into the sewage, thereby promoting the sufficient contact and oxidative decomposition of the organic matter and the microorganisms.

[0031] In order to achieve the purpose of energy saving: the outside of the liquid container 1 is provided with a photovoltaic panel for providing electric energy to the driving motor 33, and the photovoltaic panel is electrically connected with the driving motor 33.

[0032] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
