Description

Technical Field

[0001] This application relates to the field of wastewater treatment equipment technology, and in particular to a detachable and washable jet aerator. Background Technology

[0002] To achieve the reuse of paper resources, recycled paper technology is generally used to process waste paper. During the processing, a large amount of papermaking wastewater is generated, which needs to be biochemically reacted through an aerobic system to obtain water that meets the discharge standards. In order to increase the oxygen content in the papermaking wastewater, jet aerators and connecting pipeline systems need to be installed at the bottom of the biochemical reaction tank.

[0003] Due to the high calcium ion content and hardness of papermaking wastewater, the jet aerator pipeline system is prone to scaling and blockage over time. This reduces the oxygenation effect of the jet aerator and affects the efficiency of the aerobic system in treating papermaking wastewater. Furthermore, since the jet aerator and connecting pipeline system are installed at the bottom of the biological reaction tank, once a blockage occurs, the papermaking wastewater in the corresponding biological reaction tank needs to be transferred to another biological reaction tank before cleaning can be carried out. This results in high cleaning costs and a long cleaning time for the jet aerator pipeline. Utility Model Content

[0004] To reduce the cleaning cost and shorten the cleaning time of jet aerator pipelines, this application provides a detachable and washable jet aerator.

[0005] The removable and washable jet aerator provided in this application adopts the following technical solution:

[0006] A removable and washable jet aerator includes:

[0007] A main gas supply pipeline, on which multiple first branch interfaces are formed, and one end of the main gas supply pipeline is connected to a gas supply unit.

[0008] A main liquid supply pipeline, on which multiple second branch interfaces are formed, and one end of the main liquid supply pipeline is connected to a liquid supply unit;

[0009] Multiple mixing tubes, one end of which forms an outlet for a gas-liquid mixture;

[0010] Multiple gas supply pipes are provided, with one end of each gas supply pipe being detachably and fixedly connected to the first branch interface, and the other end extending into the biochemical reaction tank and connected to the mixing throat.

[0011] Multiple liquid supply pipes are provided, one end of which is detachably and fixedly connected to the second branch interface, and the other end extends into the biochemical reaction tank and is connected to the mixing throat.

[0012] By adopting the above technical solution, during the aerobic treatment of papermaking wastewater, liquid is introduced into the main liquid supply pipeline through the liquid supply unit, and gas is introduced into the main gas supply pipeline through the gas supply unit. The liquid enters the mixing throat through the liquid supply branch pipe, and the gas enters the mixing throat through the gas supply branch pipe to mix with the liquid. Then, the mixture is discharged into the papermaking wastewater in the biochemical reaction tank through the gas-liquid mixture outlet at one end of the mixing throat, thereby increasing the oxygen content of the papermaking wastewater and improving the wastewater treatment effect. After a period of use, if the liquid supply branch pipe, gas supply branch pipe, or mixing throat becomes blocked, the gas supply branch pipe and liquid supply branch pipe are disassembled, and then the gas supply branch pipe, liquid supply branch pipe, and mixing throat are cleaned and repaired. The mixing throat is removed from the biochemical reaction tank for cleaning. The designed detachable and washable jet aerator can introduce oxygen-containing gas into the air supply branch pipe through the gas supply unit and the main air supply pipeline, and can introduce papermaking wastewater into the liquid supply branch pipe through the liquid supply unit and the main liquid supply pipeline. The mixing throat can mix and fully dissolve the oxygen-containing gas and papermaking wastewater, and then discharge it into the biochemical reaction tank to increase the oxygen content. Furthermore, the detachable and fixed connection of the air supply branch pipe and the liquid supply branch pipe allows for disassembly and individual cleaning in case of blockage, without the need to empty the papermaking wastewater in the biochemical reaction tank, reducing the cleaning cost of the jet aerator pipeline and shortening the cleaning time.

[0013] In one specific implementation, the air supply pipe and the liquid supply pipe connected to the same mixing throat are in the same group, and at least one connecting rod connects the air supply pipe and the liquid supply pipe in the same group.

[0014] By adopting the above technical solution, the designed connecting rod can realize the connection between the gas supply pipe and the liquid supply pipe in the same group, thereby facilitating the reduction of the frequency of lifting using lifting equipment.

[0015] In one specific implementation, it further includes at least one fixing rod, which is simultaneously connected to multiple connecting rods in different groups.

[0016] By adopting the above technical solution, the designed fixing rod can connect different groups of gas supply pipes, liquid supply pipes and mixing pipes into a whole, further reducing the frequency of lifting using lifting equipment.

[0017] In one specific implementation scheme, a first flange is fixedly connected to the first branch interface, and a second flange is fixedly connected to one end of the gas supply branch pipe, with the first flange and the second flange bolted together.

[0018] By adopting the above technical solution, the designed first flange and second flange can be matched to realize a detachable fixed connection between the main gas supply pipeline and the gas supply branch pipeline.

[0019] In one specific implementation scheme, a third flange is fixedly connected to the second branch interface, and a fourth flange is fixedly connected to one end of the liquid supply pipe, with the third flange and the fourth flange bolted together.

[0020] By adopting the above technical solution, the designed third and fourth flanges can be matched to achieve a detachable and fixed connection between the main liquid supply pipeline and the liquid supply branch pipeline.

[0021] In one specific implementation scheme, one end of the gas supply pipe is rotatably connected to a first locking sleeve, and two first locking protrusions are connected at the first branch interface. Two first spiral locking grooves adapted to the first locking protrusions are formed on the inner wall of the first locking sleeve.

[0022] By adopting the above technical solution, the gas supply branch pipe and the first branch interface are first aligned, and then the first locking sleeve is rotated. With the cooperation of the first locking protrusion and the first spiral locking groove, the gas supply branch pipe is raised until it is pressed against the first branch interface to complete the installation. The designed first locking sleeve and the first locking protrusion can realize the detachable fixed connection between the main gas supply pipe and the gas supply branch pipe.

[0023] In one specific implementation scheme, a second locking sleeve is rotatably connected to one end of the liquid supply pipe, and two second locking protrusions are connected to the second branch interface. Two second spiral locking grooves adapted to the second locking protrusions are formed on the inner wall of the second locking sleeve.

[0024] By adopting the above technical solution, the designed second locking sleeve and second locking protrusion can achieve a detachable and fixed connection between the main liquid supply pipeline and the liquid supply branch pipeline through cooperation.

[0025] In one specific implementation, the outer periphery of the main gas supply pipe, the main liquid supply pipe, the mixing throat, the gas supply branch pipe, and the liquid supply branch pipe are all coated with a protective coating.

[0026] By adopting the above technical solution, the designed protective coating can extend the service life of the main gas supply pipeline, the main liquid supply pipeline, the mixing throat, the gas supply branch pipe, and the liquid supply branch pipe.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The designed detachable and washable jet aerator can introduce oxygen-containing gas into the air supply branch pipe through the gas supply unit and the main air supply pipeline, and can introduce papermaking wastewater into the liquid supply branch pipe through the liquid supply unit and the main liquid supply pipeline. Through the mixing throat, the oxygen-containing gas and papermaking wastewater can be mixed and fully dissolved, and then discharged into the biochemical reaction tank to increase the oxygen content. Furthermore, the detachable and fixed connection of the air supply branch pipe and the liquid supply branch pipe allows for disassembly and individual cleaning in case of blockage, without the need to empty the papermaking wastewater in the biochemical reaction tank, reducing the cleaning cost of the jet aerator pipeline and shortening the cleaning time required.

[0029] 2. The designed detachable and washable jet aerator can connect the air supply pipes and liquid supply pipes within the same group via a connecting rod, thereby facilitating a reduction in the frequency of lifting using lifting equipment.

[0030] 3. The designed detachable and washable jet aerator can achieve a detachable and fixed connection between the main air supply pipeline and the air supply branch pipeline through the cooperation of the first flange and the second flange. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0039] This application discloses a detachable and washable jet aerator.

[0040] Reference Figure 1 A detachable and washable jet aerator includes an air supply main pipe 1 and a liquid supply main pipe 2. One end of the air supply main pipe 1 is flanged and connected to a gas supply unit, and multiple first sub-ports are formed on the air supply main pipe 1, which are distributed along the setting direction of the air supply main pipe 1. One end of the liquid supply main pipe 2 is connected to a liquid supply unit, and multiple second sub-ports are formed on the liquid supply main pipe 2, which are distributed along the setting direction of the liquid supply main pipe 2.

[0041] Reference Figure 1 Furthermore, the detachable and washable jet aerator also includes a mixing throat 3, an air supply branch pipe 4, and a liquid supply branch pipe 5. The mixing throat 3, the air supply branch pipe 4, and the liquid supply branch pipe 5 are configured as a group of aeration components. In this application, there are multiple aeration components. Specifically, the mixing throat 3 has a throat formed by a venturi tube, and one end of the mixing throat 3 forms a gas-liquid mixture outlet. One end of the air supply branch pipe 4 is detachably and fixedly connected to the first branch interface, and the other end extends into the biochemical reaction tank and is welded to the mixing throat 3. The connection between the air supply branch pipe 4 and the mixing throat 3 is located downstream of the throat. One end of the liquid supply branch pipe 5 is detachably and fixedly connected to the second branch interface, and the other end extends into the biochemical reaction tank and is welded to the mixing throat 3. The connection between the liquid supply branch pipe 5 and the mixing throat 3 is located upstream of the throat.

[0042] Reference Figure 2 Specifically, the gas supply pipe 4 and liquid supply pipe 5 welded to the same mixing throat pipe 3 are in the same group, and at least one connecting rod 6 is welded and fixed between the gas supply pipe 4 and liquid supply pipe 5 in the same group. In this application, the number of connecting rods 6 welded between the gas supply pipe 4 and liquid supply pipe 5 in the same group can be one, two, or other numbers, as long as the connection between the gas supply pipe 4 and liquid supply pipe 5 can be achieved.

[0043] Reference Figure 2 Furthermore, the detachable and washable jet aerator also includes at least one fixing rod 7, which is simultaneously welded and fixed to multiple connecting rods 6 in different groups. In this application, the fixing rod 7 can be welded to two connecting rods 6 in two groups at the same time, or to three connecting rods 6 in three groups at the same time, or to other numbers, as long as multiple groups of aeration components can be connected to reduce the lifting frequency.

[0044] Reference Figure 2 In order to extend the service life of the main gas supply pipeline 1, the main liquid supply pipeline 2, the mixing throat 3, the gas supply branch pipe 4, and the liquid supply branch pipe 5, protective coatings such as anti-corrosion coatings and weather-resistant coatings are applied to the outer periphery of the main gas supply pipeline 1, the main liquid supply pipeline 2, the mixing throat 3, the gas supply branch pipe 4, and the liquid supply branch pipe 5.

[0045] Reference Figure 3 In some embodiments of this application, specifically, a first flange 11 is welded and fixed at the first branch interface, and a second flange 41 is welded to one end of the gas supply branch pipe 4.

[0046] Reference Figure 3 Specifically, a third flange 21 is welded and fixed at the second branch interface, and a fourth flange 51 is welded and fixed at one end of the liquid supply pipe 5. The third flange 21 and the fourth flange 51 are coaxially arranged and connected by multiple bolts and nuts.

[0047] Reference Figure 4 and Figure 5 In some other embodiments of this application, a first locking sleeve 42 is rotatably connected to one end of the gas supply pipe 4. Specifically, a first fixing ring is coaxially welded to the gas supply pipe 4, and a first annular groove that mates with the first fixing ring is formed on the first locking sleeve 42. Rotation is achieved through the first fixing ring and the first annular groove. Furthermore, a first sealing ring is bonded to the lower end face of the first fixing ring. Two first locking protrusions 12 are welded and fixed at the first branch interface. Two first spiral locking grooves 421 that are adapted to the first locking protrusions 12 are formed on the inner wall of the first locking sleeve 42. By rotating the first locking sleeve 42, the gas supply pipe 4 moves closer to the first branch interface until it abuts. At this time, the bottom wall of the first annular groove abuts against the first sealing ring, and a seal is also achieved.

[0048] Reference Figure 4 and Figure 6 One end of the liquid supply pipe 5 is rotatably connected to a second locking sleeve 52. Specifically, a second fixing ring is coaxially welded to the liquid supply pipe 5, and a second annular groove is formed on the second locking sleeve 52 to cooperate with the second fixing ring. Rotation is achieved through the second fixing ring and the second annular groove. Furthermore, a second sealing ring is bonded to the lower end face of the second fixing ring. Two second locking protrusions 22 are welded and fixed at the second branch interface. Two second spiral locking grooves 521 that are adapted to the second locking protrusions 22 are formed on the inner wall of the second locking sleeve 52. By rotating the second locking sleeve 52, the liquid supply pipe 5 moves closer to the second branch interface until it abuts. At this time, the bottom wall of the second annular groove abuts against the second sealing ring, and a seal is also achieved.

[0049] The implementation principle of a detachable and washable jet aerator according to an embodiment of this application is as follows: When aerobically treating papermaking wastewater, liquid is input into the main liquid supply pipe 2 through the liquid supply unit, and gas is input into the main air supply pipe 1 through the gas supply unit. The liquid enters the mixing throat 3 through the liquid supply branch pipe 5, and the gas enters the mixing throat 3 through the air supply branch pipe 4 to mix with the liquid. Then, the mixture is discharged into the papermaking wastewater in the biochemical reaction tank through the gas-liquid mixture outlet at one end of the mixing throat 3, thereby increasing the oxygen content of the papermaking wastewater and improving the wastewater treatment effect. After a period of use, if the liquid supply branch pipe 5, the air supply branch pipe 4, or the mixing throat 3 becomes blocked, the air supply branch pipe 4 and the liquid supply branch pipe 5 are disassembled, and then the air supply branch pipe 4, the liquid supply branch pipe 5, and the mixing throat 3 are removed from the biochemical reaction tank for cleaning.

[0050] Oxygen-containing gas can be introduced into the gas supply branch pipe 4 through the cooperation of the gas supply unit and the main gas supply pipe 1. Papermaking wastewater can be introduced into the liquid supply branch pipe 5 through the cooperation of the liquid supply unit and the main liquid supply pipe 2. The oxygen-containing gas and papermaking wastewater can be mixed and fully dissolved through the mixing throat pipe 3, and then discharged into the biochemical reaction tank to increase the oxygen content. Furthermore, the detachable fixed connection of the gas supply branch pipe 4 and the liquid supply branch pipe 5 allows for disassembly and individual cleaning in case of blockage, eliminating the need to drain the papermaking wastewater from the biochemical reaction tank, reducing the cleaning cost of the jet aerator pipeline and shortening the cleaning time.

[0051] 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.
