Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a disinfection device for wastewater treatment. Background Technology

[0002] Wastewater disinfection, a crucial step in wastewater treatment, aims to kill pathogens such as bacteria, viruses, and parasites in wastewater, preventing disease transmission and protecting public health and the ecological environment. Common methods include chlorination disinfection, which utilizes the reaction of chlorine gas or chlorine-containing compounds in water to generate strong oxidizing substances such as hypochlorous acid, destroying the structure of pathogens; ultraviolet disinfection, which uses specific wavelengths of ultraviolet light to destroy the genetic material of microorganisms; and ozone disinfection, which uses the strong oxidizing properties of ozone to oxidize pathogens. Different disinfection methods have their own advantages and disadvantages, and in practical applications, factors such as cost, disinfection effectiveness, and secondary pollution must be comprehensively considered to select the appropriate disinfection method.

[0003] National Patent Application No. CN215516959U discloses a disinfection device for wastewater treatment. It states that it "includes a base, with two support rods fixedly connected to the upper end of the base, and a housing fixedly connected to the upper ends of the two support rods. A water outlet pipe is provided at the lower end of the housing… This allows sediment inside the housing to be carried out, facilitating cleaning of the filter screen and the interior of the housing; the wastewater is stirred using a stirring fan blade, ensuring more thorough mixing of the wastewater and disinfectant." However, the prior art only describes one stirring mechanism. Unidirectional stirring not only prolongs the mixing time between wastewater and disinfectant but may also result in insufficient mixing. Furthermore, the filter screen lacks a disassembly structure, making replacement or cleaning inconvenient and impacting disinfection efforts. Therefore, this application proposes a disinfection device for wastewater treatment to meet this need. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices, such as the inability to guarantee the mixing efficiency and effect of sewage and disinfectant, and the inconvenience of replacing or cleaning the filter screen, this utility model provides a disinfection device for sewage treatment.

[0005] The technical implementation scheme of this utility model is as follows: a disinfection device for sewage treatment includes a disinfection tank, with mounting seats on both sides of the disinfection tank, and mounting frames on the inner sides of the two sets of mounting seats. A first motor is mounted at the top center of the mounting frame, and a stirring paddle fixedly connected to the drive shaft of the first motor is mounted at the bottom of the mounting frame. Connecting rods are fixedly connected to both sides of the bottom of the mounting frame. A filter screen adapted to the size of the disinfection tank is provided below the connecting rods. An installation component is provided at the connection between the filter screen and the connecting rods, and a drive component is provided at the bottom of the disinfection tank.

[0006] Optionally, the inner surface of the mounting base is provided with a lifting groove, and the outer surface of the mounting frame is fixedly connected to a lifting plate that is slidably connected to the lifting groove and has several sets of locking teeth fixedly connected to the outer surface. A second motor is installed on one side of the top of the mounting base, and the gear is fixedly connected to the drive shaft of the second motor and meshes with the locking teeth of the lifting plate.

[0007] Optionally, the mounting assembly includes a mounting block, a mounting groove, a mounting hole, a through groove, and a mounting rod. The mounting block is fixedly connected to both sides of the top of the filter screen. The mounting groove is opened on the top surface of the mounting block and is adapted to the size of the connecting rod. The mounting hole passes through the connecting rod near the bottom. The through groove passes through the inner wall of one side of the mounting groove. The mounting rod is movably connected to the through groove and is adapted to the size of the mounting hole.

[0008] Optionally, the mounting assembly further includes a slide groove, a slider, a spring, and a pull block. The slide groove is formed on the inner wall of the through groove. The slider is fixedly connected to the outer periphery of the mounting rod and slidably connected to the slide groove. The spring is sleeved on the outer periphery of the mounting rod and its two ends are respectively fixedly connected to the inner wall of the slider on the side away from the mounting groove and the slide groove on the side away from the mounting groove. The pull block is fixedly connected to the outer end of the mounting rod.

[0009] Optionally, the drive assembly includes a base, a cavity, and a rotating shaft. The base is fixedly connected to the bottom of the mounting base, the cavity is opened inside the base and its top inner wall is connected to the outside, and the rotating shaft is fixedly connected to the bottom of the disinfection bucket and rotatably connected to the bottom inner wall of the cavity.

[0010] Optionally, the drive assembly further includes a worm gear, a worm, a third motor, a transmission wheel, and a transmission belt. The worm gear is fixedly connected to the outer periphery of the rotating shaft. The two ends of the worm are rotatably connected to the inner walls of both sides of the cavity and mesh with the worm gear. The motor is installed inside the cavity and is located on one side of the worm. Two sets of transmission wheels are provided and are fixedly connected to the drive shaft of the third motor and one end of the worm, respectively. The transmission belt is wound around the two sets of transmission wheels.

[0011] Optionally, the drive assembly further includes a limiting groove and a limiting ring. The limiting groove is formed on the top surface of the base, and the limiting ring is fixedly connected to the bottom of the disinfection barrel and rotatably connected to the limiting groove.

[0012] This utility model has the following advantages:

[0013] 1. This utility model features an installation assembly. Pulling the pull block outward causes the mounting rod to drive the slider outward along the groove, compressing the spring. When the mounting rod moves out of the groove, the filter screen is placed at the bottom of the connecting rod, which is then inserted into the groove. Releasing the pull block causes the spring to rebound, driving the mounting rod inward via the slider. When the mounting rod is inserted into the mounting hole, the connecting rod is fixed in the groove, completing the filter screen installation. Pulling the pull block outward causes the mounting rod to move outward. When the mounting rod moves out of the mounting hole, the filter screen is moved downward until the connecting rod moves out of the groove, completing the filter screen removal. This design simplifies and speeds up filter screen installation and removal, effectively improving filter screen replacement and cleaning efficiency.

[0014] 2. This utility model incorporates a drive assembly. Starting the third motor causes it to drive the transmission wheel at one end of its drive shaft. Since the transmission belt wraps around the two sets of transmission wheels, the worm gear rotates synchronously with the drive shaft of the third motor. Because the worm wheel meshes with the worm, it rotates along with the worm. The worm wheel, in turn, drives the disinfection tank to rotate in the opposite direction to the stirring paddle via a rotating shaft. During the rotation of the disinfection tank, a limiting ring rotates synchronously along the limiting groove with the disinfection tank and limits its movement, thus preventing the disinfection tank from tilting. This design allows the disinfection tank to rotate in the opposite direction to the stirring paddle, thereby improving the mixing efficiency and effect of wastewater and disinfectant.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] A disinfection device for wastewater treatment includes a disinfection tank 1, with mounting bases 2 on both sides of the disinfection tank 1. Mounting frames 3 are installed inside the two sets of mounting bases 2. A first motor 4 is mounted at the top center of the mounting frame 3. A stirring paddle 5, fixedly connected to the drive shaft of the first motor 4, is installed at the bottom of the mounting frame 3. Connecting rods 6 are fixedly connected to both sides of the bottom of the mounting frame 3. A filter screen 7, matching the size of the disinfection tank 1, is installed below the connecting rods 6. An installation assembly 8 is installed at the connection point between the filter screen 7 and the connecting rods 6. A drive assembly 9 is installed at the bottom of the disinfection tank 1.

[0023] It should be noted that the installation component 8 enables the filter screen 7 to be quickly installed and removed, thereby improving the replacement and cleaning efficiency of the filter screen 7. The drive component 9 enables the disinfection tank 1 to rotate in the opposite direction to the stirring paddle 5, thereby making the disinfectant and sewage more thoroughly mixed.

[0024] like Figure 1 As shown, the inner surface of the mounting base 2 is provided with a lifting groove 10, and the outer surface of the mounting frame 3 is fixedly connected to a lifting plate 11 that is slidably connected to the lifting groove 10 and has several sets of locking teeth fixedly connected to the outer surface. A second motor 12 is installed on one side of the top of the mounting base 2, and a gear 13 is fixedly connected to the drive shaft of the second motor 12 and meshes with the locking teeth of the lifting plate 11.

[0025] It should be noted that starting the second motor 12 will drive the gear 13 to rotate. Since the gear 13 meshes with the teeth of the lifting plate 11 and the lifting plate 11 is slidably connected to the lifting groove 10, when the gear 13 rotates, it will drive the lifting plate 11 to slide up and down in the lifting groove 10, thereby driving the mounting frame 3 to rise and fall.

[0026] like Figure 2 and Figure 3 As shown, the mounting assembly 8 includes a mounting block 81, a mounting groove 82, a mounting hole 83, a through groove 84, and a mounting rod 85. The mounting block 81 is fixedly connected to both sides of the top of the filter screen 7. The mounting groove 82 is opened on the top surface of the mounting block 81 and is adapted to the size of the connecting rod 6. The mounting hole 83 penetrates the connecting rod 6 near the bottom. The through groove 84 penetrates the inner wall of one side of the mounting groove 82. The mounting rod 85 is movably connected to the through groove 84 and is adapted to the size of the mounting hole 83.

[0027] It should be noted that after placing the connecting rod 6 into the mounting groove 82, insert the mounting rod 85 into the mounting hole 83. At this time, the connecting rod 6 can be fixed in the mounting groove 82, thus completing the installation of the filter screen 7 and the connecting rod 6. Remove the mounting rod 85 from the mounting hole 83, and then remove the connecting rod 6 from the mounting groove 82. At this time, the filter screen 7 can be removed.

[0028] like Figure 3 As shown, the mounting assembly 8 also includes a slide groove 86, a slider 87, a spring 88, and a pull block 89. The slide groove 86 is formed in the inner wall of the through groove 84. The slider 87 is fixedly connected to the outer periphery of the mounting rod 85 and slidably connected to the slide groove 86. The spring 88 is sleeved on the outer periphery of the mounting rod 85 and its two ends are fixedly connected to the inner wall of the slider 87 away from the mounting groove 82 and the slide groove 86 away from the mounting groove 82, respectively. The pull block 89 is fixedly connected to the outer end of the mounting rod 85.

[0029] It should be noted that pulling the pull block 89 outward will cause the slider 87 to slide outward along the slide groove 86 via the mounting rod 85, thus compressing the spring 88. Releasing the pull block 89 will cause the spring 88 to rebound, which will then cause the mounting rod 85 to move inward via the slider 87.

[0030] like Figure 4 and Figure 5 As shown, the drive assembly 9 includes a base 91, a cavity 92, and a rotating shaft 93. The base 91 is fixedly connected to the bottom of the mounting base 2. The cavity 92 is opened inside the base 91 and its top inner wall is connected to the outside. The rotating shaft 93 is fixedly connected to the bottom of the disinfection tank 1 and rotatably connected to the bottom inner wall of the cavity 92.

[0031] It should be noted that rotating the shaft 93 will drive the disinfection tank 1 to rotate synchronously, thereby making the disinfectant and sewage mix more thoroughly.

[0032] like Figure 5As shown, the drive assembly 9 also includes a worm gear 94, a worm 95, a third motor 96, a transmission wheel 97, and a transmission belt 98. The worm gear 94 is fixedly connected to the outer periphery of the rotating shaft 93. The two ends of the worm 95 are rotatably connected to the inner walls of both sides of the cavity 92 and mesh with the worm gear 94. The motor is installed inside the cavity 92 and is located on one side of the worm 95. Two sets of transmission wheels 97 are provided and are fixedly connected to the drive shaft of the third motor 96 and one end of the worm 95, respectively. The transmission belt 98 is wound around the two sets of transmission wheels 97.

[0033] It should be noted that starting the third motor 96 will drive the transmission wheel 97 at one end of its drive shaft to rotate. Since the transmission belt 98 is wrapped around the two sets of transmission wheels 97, the worm 95 will rotate synchronously with the drive shaft of the third motor 96. Since the worm wheel 94 meshes with the worm 95, the worm wheel 94 will rotate along with the rotation of the worm 95.

[0034] like Figure 4 As shown, the drive assembly 9 also includes a limiting groove 99 and a limiting ring 910. The limiting groove 99 is opened on the top surface of the base 91, and the limiting ring 910 is fixedly connected to the bottom of the disinfection tank 1 and rotatably connected to the limiting groove 99.

[0035] It should be noted that during the rotation of the disinfection tank 1, the limiting ring 910 will rotate synchronously with the disinfection tank 1 along the limiting groove 99 and limit it, thereby preventing the disinfection tank 1 from tilting.

[0036] In a specific application scenario, firstly, pull the pull block 89 outwards so that it drives the slider 87 to slide outwards along the groove 86 via the mounting rod 85, compressing the spring 88. When the mounting rod 85 moves out of the mounting groove 82, place the filter screen 7 at the bottom of the connecting rod 6 and insert the connecting rod 6 into the mounting groove 82. Then, release the pull block 89, and the spring 88 will rebound, driving the mounting rod 85 inwards via the slider 87. When the mounting rod 85 is inserted into the mounting hole 83, the connecting rod 6 is fixed in the mounting groove 82, thus completing the filter screen 7 installation. After installation, the second motor 12 is started to drive the gear 13 to rotate. Since the gear 13 meshes with the teeth of the lifting plate 11 and the lifting plate 11 is slidably connected to the lifting groove 10, the rotation of the gear 13 will drive the lifting plate 11 to slide up and down in the lifting groove 10, thereby driving the mounting frame 3 to rise and fall. When the filter screen 7 descends to the bottom of the disinfection tank 1 with the mounting frame 3, the second motor 12 is turned off and sewage and disinfectant are added to the disinfection tank 1. Then, the first motor 4 is started to drive the stirring paddle 5 to rotate and mix the sewage and disinfectant. Then, the third motor 96 is started, causing the transmission wheel 97 at one end of its drive shaft to rotate. Since the transmission belt 98 is wrapped around the two sets of transmission wheels 97, the worm 95 will rotate synchronously with the drive shaft of the third motor 96. Since the worm wheel 94 meshes with the worm 95, the worm wheel 94 will rotate with the rotation of the worm 95. The worm wheel 94, in turn, drives the disinfection tank 1 to rotate in the opposite direction to the stirring paddle 5 through the rotating shaft 93, thereby improving the mixing efficiency and effect of wastewater and disinfectant. During the rotation of the disinfection tank 1, the limiting ring 910 will move along the limiting ring. The groove 99 rotates synchronously with the disinfection tank 1 and limits its movement, thereby preventing the disinfection tank 1 from tilting. After disinfection, the first motor 4 and the third motor 96 are turned off and the second motor 12 is restarted to drive the mounting bracket 3 to rise. When the filter screen 7 is removed from the disinfection tank 1, the pull block 89 is pulled outward again to drive the mounting rod 85 to move outward. When the mounting rod 85 is removed from the mounting hole 83, the filter screen 7 is moved downward until the connecting rod 6 is removed from the mounting groove 82. At this point, the filter screen 7 can be disassembled and replaced or cleaned.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
