Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to energy-saving and environmentally friendly wastewater purification aeration treatment equipment. Background Art

[0002] In the wastewater treatment process, aeration equipment is one of the key equipment, especially in the treatment of municipal sewage and industrial wastewater. The main function of aeration equipment is to transfer oxygen in the air to the liquid in the aeration tank through specific technical means to supply the oxygen required for the metabolism of aerobic microorganisms, and at the same time achieve full and uniform mixing of the water in the tank to achieve the purpose of biological treatment.

[0003] Existing aeration devices are usually located at the bottom of the aeration tank. This design makes it easy for dirt and impurities in the aeration tank to deposit around the aeration holes, thereby blocking the aeration holes and affecting the normal operation of the aeration equipment. Blockage of aeration holes will not only lead to a decrease in aeration efficiency, but also increase the energy consumption and maintenance cost of the equipment. Because the parameters such as the power efficiency, oxygenation capacity and oxygen transfer rate of the aeration equipment will drop significantly when the aeration holes are blocked, more energy is required to maintain the necessary aeration effect; in addition, during the aeration process, a large amount of foam will be generated on the water surface of the aeration tank. The foam is composed of tiny bubbles, suspended matter in sewage and microbial metabolites, which float on the water surface of the aeration tank to form a barrier layer, which seriously hinders the contact between the liquid and the air, thereby affecting the dissolved oxygen content. The presence of foam not only reduces the aeration effect, but also has an adverse effect on subsequent sewage treatment steps, such as affecting the sedimentation effect and effluent water quality.

[0004] The invention patent with application number "CN202210947780.5" discloses an aerator for industrial wastewater treatment, including a fixed shell and a rotating head that is rotatably sleeved on the upper end of the fixed shell and driven by a rotating head driving assembly to rotate, and a plurality of telescopic parts that can be extended and retracted are arranged on the rotating head; each of the telescopic parts is provided with a plurality of oxygen injection ports; the lower end of the fixed shell is provided with an air inlet, and the air inlet is connected with the plurality of oxygen injection ports; one end of each of the telescopic parts is hinged to the rotating head and driven by a driving disk to perform telescopic switching, during which the moving block moves and resets and drives the telescopic part to retract under the cooperation of the reset part. This application adjusts the horizontal height of the aeration device by telescoping the telescopic rod. Although the aeration efficiency is improved to a certain extent, the blockage of the vibration aeration hole and the foaming problem of the aeration tank are not dealt with, which will still cause high maintenance costs and affect the sedimentation effect and effluent water quality during use.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please refer to the attached Figure 1-9 , the present embodiment is an energy-saving and environmentally friendly wastewater purification aeration treatment equipment: it includes a base 1, an aeration tube 2 is fixedly connected to the base 1, an aeration cylinder 3 is slidably connected to the aeration tube 2, an aeration hole 4 is provided on the side of the aeration cylinder 3, an anti-clogging sleeve 5 is provided on the outer side of the aeration hole 4, the anti-clogging sleeve 5 is fixedly connected to the base 1, an air outlet 6 is provided at the upper end of the aeration cylinder 3, and the outer end of the air outlet 6 is connected to a hollow telescopic frame 7, one end of the telescopic frame 7 is fixedly connected to the aeration cylinder 3, and the other end of the telescopic frame 7 is rotatably connected to a de-floating mechanism 8, and the upper end of the de-floating mechanism 8 is fixedly connected to an air nozzle 903 driving mechanism, and the interior of the air nozzle 903 driving mechanism is connected to the air outlet 6.

[0036] The aeration pipe 2 is located in the middle of the base 1, and the aeration pipe 2 is vertically upward. An air pump connected to the aeration pipe 2 is installed in the base 1, and a continuous supply of gas is provided to the aeration pipe 2 through the working position of the air pump. The aeration cylinder 3 is sleeved on the outside of the aeration pipe 2, and the anti-clogging sleeve 5 is sleeved on the outside of the aeration cylinder 3. The aeration cylinder 3 is tightly connected with the anti-clogging sleeve 5. The aeration cylinder 3 is sequentially provided with a telescopic frame 7, a de-foaming mechanism 8 and a gas nozzle 903 driving mechanism upward. The telescopic frame 7 is used to adjust the height of the de-foaming mechanism 8 and the gas nozzle 903 driving mechanism. When in use, the de-foaming mechanism 8 and the gas nozzle 903 driving mechanism are located at the liquid in the aeration tank. Above the surface, the de-foaming mechanism 8 drives the driving mechanism to be driven, and the power of the air nozzle 903 driving mechanism is provided by the gas ejected outward through the air outlet 6, and the gas driving mechanism is driven to rotate by the air pressure difference. At the same time, the airflow ejected by the air nozzle 903 driving mechanism will also act on the liquid surface in the aeration tank, and part of the floating foam on the liquid surface will be blown away by the airflow to avoid the floating foam affecting the dissolved oxygen efficiency of the aeration tank. The rotation of the de-foaming mechanism 8 is driven by the airflow, which not only simplifies the equipment structure, but also improves the utilization of energy. The gas required for de-foaming directly enters the aeration process without the need to provide an additional power source.

[0037] The de-foaming mechanism 8 includes a connecting block 801, which is rotatably connected to the telescopic frame 7. A connecting tube 802 is fixedly connected to the upper end of the connecting block 801, a floating plate 803 is fixedly connected to the connecting tube 802, an annular air bag 804 is fixedly connected below the floating plate 803, a sliding sleeve 805 is slidably connected to the upper side of the floating plate 803, a traction rope 806 is fixedly connected to the sliding sleeve 805, and a counterweight ball 807 is fixedly connected to the end of the traction rope 806.

[0038] The connecting block 801 is the connecting point between the de-foaming mechanism 8 and the telescopic frame 7. The rotating connection between the connecting block 801 and the telescopic frame 7 is the same as the principle of the rotary joint, which allows the de-foaming mechanism 8 to rotate on the telescopic frame 7 without affecting the gas in the air outlet 6 to be transported to the connecting pipe 802 through the hollow telescopic frame 7. The connecting pipe 802 is fixedly connected to the upper end of the connecting block 801. On the one hand, the connecting pipe 802 supports the floating plate 803. On the other hand, the connecting pipe 802 transfers the gas to the driving assembly of the air nozzle 903. The floating plate 803 is a columnar structure. There are multiple air bags 804 under the floating plate 803. The air bags 804 are annular structures. The air bags 804 are installed at the bottom of the floating plate 803. When the air bags 804 are inflated, the buoyancy of the floating plate 803 will increase. The buoyancy of the floating plate 803 will overcome the deadweight of the de-foaming mechanism 8 and the driving mechanism of the air nozzle 903, and drive the telescopic frame 7 to adjust the length, thereby ensuring the floating plate 803 After the plate 803 contacts the liquid surface, the floating plate 803 will be suspended above the liquid surface, the counterweight ball 807 and the traction rope 806 are located above the floating plate 803, the counterweight ball 807 is a solid sphere with a relatively large density, the traction rope 806 is located between the solid ball and the sliding sleeve 805, and the traction rope 806 has good toughness. When the floating plate 803 rotates, due to the large weight of the solid ball, under the action of centrifugal force, the solid ball drives the traction rope 806 to move outward relative to the floating plate 803, and at the same time, the solid ball will continue to rotate with the floating plate 803, and the traction rope 806 is pulled outward by the solid ball, so that the rotation area of ​​the solid ball is increased. With the rotation of the solid ball and the traction rope 806, the floating foam in the aeration tank will be cut and broken, and the divided floating foam will be blown away under the airflow of the air nozzle 903 of the air nozzle 903 driving mechanism, thereby completing the removal of the floating foam in the aeration tank, avoiding the floating foam from affecting the dissolved oxygen efficiency of the wastewater in the aeration tank, and improving the efficiency of wastewater treatment.

[0039] The air nozzle 903 driving mechanism includes a four-way joint 901, the bottom of the four-way joint 901 is connected to the connecting pipe 802, the upper end of the four-way joint 901 is fixedly connected to three beveled elbows 902 distributed at equal angles, and the end of the beveled elbow 902 is fixedly connected to the air nozzle 903.

[0040] The connecting hole at the bottom of the four-way joint 901 is fixedly connected to the connecting pipe 802, and the three connecting holes on the upper side of the four-way joint 901 are used for diversion. Three bevel elbows 902 are correspondingly connected to the upper side of the four-way joint 901. The bevel elbows 902 are distributed at equal angles on the upper end of the four-way joint 901 to ensure that the gas can be evenly distributed and generate a balanced driving force. The gas that passes through the air outlet 6 enters the bevel elbow 902 through the four-way joint 901 and is ejected from the gas nozzle 903. Due to the special design of the bevel elbow 902, the gas will generate a torque perpendicular to the injection direction. This torque will act on the four-way joint 901 to cause it to rotate. Since the three bevel elbows 902 are distributed at equal angles, the torques they generate will balance each other, thereby ensuring that the four-way joint 901 can rotate smoothly and continuously. The bevel elbow 902 is connected to the gas nozzle 903, and the gas nozzle 903 is slightly bent downward, and the gas is ejected onto the wastewater surface or a specific area through the gas nozzle 903.

[0041] Three groups of traction ropes 806 are connected to the sliding sleeve 805. In order to store the traction ropes 806 and the counterweight block in a standardized manner without affecting the work of the traction ropes 806 and the counterweight block, a hole groove is opened in the middle of the sliding sleeve 805. The sliding sleeve 805 is sleeved on the connecting pipe 802. The first spring 808 exerts an upward force on the sliding sleeve 805. In the initial state, the sliding sleeve 805 drives the traction rope 806 away from the position of the floating plate 803. When the floating plate 803 rotates, the centrifugal force of the counterweight ball 807 drives the sliding sleeve 805 downward to compress the first spring 808 through the traction rope 806. 08. When the sliding sleeve 805 moves downward, the outward extension length of the traction rope 806 becomes longer, thereby not affecting the work of the traction rope 806 and the counterweight ball 807. The reversing wheel 809 is a fixed pulley. The reversing wheel 809 is located above the traction rope 806. The reversing wheel 809 reduces the friction coefficient of the traction rope 806 and facilitates the back and forth movement of the traction rope 806. The guide block 810 guides the traction rope 806 to avoid mutual entanglement between the three groups of traction ropes 806, and also neatly places the three groups of traction ropes 806 above the floating plate 803.

[0042] The rotary joint is rotatably installed in the aeration hole 4. The aeration cylinder 3 is surrounded by a circle of aeration holes 4 on the side. The interior of the aeration cylinder 3 is a closed space. When the aeration pipe 2 exhausts air outward, the quality of the interior of the aeration cylinder 3 is enhanced, and the gas in the aeration cylinder 3 is discharged outward through the aeration hole 4. A cavity connected to the aeration hole 4 is provided inside the rotary joint. A boost hole 12 is provided on the outside of the rotary joint. The boost hole 12 is installed on the guard plate 11. The guard plate 11 is an arc-shaped structure. The edge of the guard plate 11 is tangent to the cylindrical surface of the rotary joint. The boost hole 12 is located on the side of the rotary joint. In order to prevent the rotary joint from affecting the mutual influence between the anti-clogging sleeve 5 and the aeration cylinder 3, the rotary joint The length is less than the length of the aeration hole 4, and the rotary joint is completely placed in the aeration hole 4. At the same time, in order to prevent the boost hole 12 of the rotary joint from acting on the side wall of the aeration cylinder 3 during jetting, a wedge-shaped surface is written on the side of the guard plate 11, and the boost hole 12 is located at the wedge-shaped surface, so that the airflow ejected from the boost hole 12 is ejected outward along a certain inclined angle, avoiding the airflow from colliding with the outer wall of the aeration cylinder 3, ensuring the impact effect of the airflow on the liquid, and under the action of the boost hole 12 and the guard plate 11, the rotary joint rotates while discharging air during aeration, thereby increasing the range of action of the boost hole 12, ensuring the aeration effect of the device at the bottom of the aeration tank, and avoiding the occurrence of aeration dead corners.

[0043] The second slide bar 703 in the telescopic frame 7 is sleeved on the first slide bar 702. The outer side of the first slide bar 702 is a columnar structure. The second slide bar 703 is provided with a through groove that cooperates with the first slide bar 702. The purpose of adjusting the length of the telescopic frame 7 is achieved through the relative sliding of the first slide bar 702 and the second slide bar 703. Furthermore, in order to enable the telescopic frame 7 to automatically adjust its length according to the depth of the aeration tank when in use, a first cushion block 705 is installed on the first support rod 701 and the first slider. Similarly, a second cushion block 706 is installed between the second slider and the second support rod 704. The first cushion block 705 and the second cushion block 706 are connected by a support rod 707. There are multiple support rods 707. The multiple support rods 707 surround the first support rod 701. Around the first pad 705 and the second pad 706, the second spring 709 exerts an upward elastic force on the baffle 710, thereby ensuring that in the initial state, the first pad 705 and the second pad 706 are in a relatively close position. At this time, the telescopic frame 7 is in a retracted state, and the overall volume of the device will be relatively small, which is convenient for movement and transportation. After the device is installed in the aeration tank, under the action of the floating plate 803, the second support rod 704 receives an upward traction force, and the second support rod 704 has a tendency to drive the second pad 706 to move upward. The second pad 706 compresses the second spring 709 upward, thereby causing the second slide bar 703 to move upward relative to the first slide bar 702, and the telescopic frame 7 is automatically adjusted according to the depth of the liquid surface in the aeration tank.

[0044] In order to further increase the sealing between the aeration cylinder 3 and the aeration pipe 2, a sealing plate 14 is installed below the aeration cylinder 3. The sealing plate 14 is slidably connected to the anti-clogging sleeve 5 through the guide rod 13. The diameter of the sealing plate 14 is larger than the diameter of the aeration cylinder 3. The sealing plate 14 slides vertically in the guide rod 13. Under the limit of the guide rod 13, the aeration cylinder 3 is prevented from escaping from the anti-clogging sleeve 5 upward. A slot hole matching the aeration pipe 2 is provided in the middle of the sealing plate 14. The length of the aeration pipe 2 is larger than the height of the guide rod 13. After the aeration cylinder 3 moves upward, the aeration pipe 2 is prevented from moving upward. Out of the aeration cylinder 3, further, in order to make the aeration cylinder 3 fall back into the anti-clogging sleeve 5 in the non-working state, a third spring 15 is installed on the guide rod 13 to ensure the smooth return of the aeration cylinder 3. At the same time, the elastic coefficient of the third spring 15 is greater than the elastic coefficient of the second spring 709. When the second gasket in the telescopic frame 7 compresses and pulls the second spring 709, this traction force is less than the elastic force of the third spring 15. The third spring 15 is compressed by the air pressure of the aeration pipe 2. When the aeration pipe 2 is closed, it falls back smoothly under the action of the third spring 15 and its own weight.

[0045] Example 2

[0046] The structure is the same as the above embodiment. Fig.10 As shown, the specific difference of this embodiment is that: a fixing hole 17 is provided on the telescopic frame 7 and the connecting block 801, and a fixing bolt is installed in the fixing hole 17, the aeration cylinder 3 is rotatably connected to the anti-clogging sleeve 5, and the sealing plate 14 is rotatably installed below the aeration cylinder 3, and a stirring mechanism is installed on the aeration cylinder 3 and the telescopic frame 7, and the stirring mechanism includes a supercharger turbine 18, and the supercharger turbine 18 is fixedly connected to the aeration cylinder 3, and the supercharger turbine 18 is provided with a slot for the telescopic frame 7 to pass through, and a stirring rod 19 is provided above the supercharger turbine 18, and the stirring rod 19 is fixedly connected to the telescopic frame 7.

[0047] A fixing component is installed between the telescopic frame 7 and the de-foaming mechanism 8. The fixing component consists of a fixing hole 17 and a fixing bolt. The fixing hole 17 and the fixing bolt fix the connecting block 801 and the telescopic frame 7 together to limit the relative rotation of the two, so that the air nozzle 903 driving mechanism drives the telescopic frame 7 and the aeration cylinder 3 to rotate synchronously when driving the de-foaming mechanism 8 to rotate. The booster turbine 18 on the aeration cylinder 3 and the stirring rod 19 on the telescopic frame 7 are both located in the aeration tank. The rotation of the booster turbine 18 and the stirring rod 19 will stir the liquid in the aeration tank, improve the fluidity of the liquid in the aeration tank, and increase the aeration effect of the liquid in the aeration tank.

[0048] Furthermore, in order to increase the range of action of the device in the aeration tank and avoid the occurrence of aeration dead corners in the aeration tank, a driving rail 20 is installed at the bottom of the base 1. The length of the driving rail 20 remains the same in the aeration tank. Mounting seats 21 are provided at both ends of the driving rail 20. The mounting seats 21 are fixed to the bottom of the aeration tank by expansion screws. The driving rail 20 is a transverse driver, and the base 1 can reciprocate on the driving rail 20. Through the action of the driving rail 20, it can move horizontally freely in the aeration tank, thereby avoiding the occurrence of aeration dead corners during the aeration process and improving the effect of wastewater treatment.

[0049] The overall working process of the present invention is as follows: in the initial state, the aeration cylinder 3 is located in the anti-clogging sleeve 5, and the telescopic frame 7 is in the shortest retracted state, and the traction rope 806 and the counterweight ball 807 in the de-foaming mechanism 8 are located on the floating plate 803. At this time, the device is in the smallest volume state. When in use, the base 1 is installed at the bottom of the aeration tank. After the base 1 is installed, the airbag 804 at the lower end of the floating plate 803 is inflated according to the state of the floating plate 803. After the airbag 804 is inflated to a certain degree, the airbag 804 drives the floating plate 803 to move upward, and the floating plate 803 moves upward with The second support rod 704 is driven to move upward. The second support rod 704 will compress the second spring 709 after receiving the upward buoyancy, thereby lengthening the telescopic frame 7. When the floating plate 803 is located above the liquid surface, the telescopic frame 7 remains stable. During aeration, the aeration pipe 2 and the bellows 16 release air outward. The aeration pipe 2 faces the top wall of the aeration cylinder 3. The gas in the aeration pipe 2 exerts an upward force on the aeration cylinder 3. The aeration cylinder 3 is forced to compress the third spring 15 upward, thereby moving the aeration cylinder 3 upward relative to the anti-blocking sleeve 5. The upward movement of the aeration cylinder 3 will leak out the position of the explosion hole, and the aeration cylinder 3 will be released. The gas in the aeration tube 3 diffuses outward through the aeration hole 4 and the rotating head 10. The rotating head 10 aerates outward and rotates under the action of the supercharging hole 12 and the guard plate 11. When the aeration tube 3 moves upward, the aeration tube 3 drives the telescopic frame 7, the de-foaming mechanism 8 and the air nozzle 903 driving mechanism on the upper side to move upward synchronously. At this time, the bottom of the floating plate 803 is separated from the water surface. After the buoyancy at the bottom of the floating plate 803 is reduced, the second spring 709 drives the second cushion block 706 downward to automatically adjust the length of the telescopic frame 7. The gas ejected from the bellows 16 enters into the water through the air outlet 6 and the telescopic frame 7. In the connecting pipe 802, the connecting pipe 802 divides the gas into three parts under the action of the four-way joint 901, and the three parts of gas are ejected outward through the gas nozzle 903. The airflow passes through the bevel elbow 902 and the nozzle to provide a torsional force for the four-way joint 901 and the connecting pipe 802. The rotation of the connecting pipe 802 drives the floating plate 803 to rotate, and the rotation of the floating plate 803 drives the counterweight ball 807 and the traction rope 806 to rotate synchronously. When the counterweight ball 807 rotates, it pulls the traction rope outward under the action of centrifugal force, thereby increasing the range of action of the counterweight ball 807, and breaking and cutting the floating foam on the surface of the aeration tank.
