Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a continuous treatment device for kitchen waste wastewater. Background Technology

[0002] Food waste refers to the waste generated in daily life activities such as food processing, catering services, and catering services provided by institutions. It includes discarded vegetable leaves, leftover food, fruit peels, etc. Its main sources are family kitchens, restaurants, hotels, and other food processing-related industries. Food waste contains extremely high levels of moisture and organic matter, is easily decomposed, and produces foul odors. Therefore, it is necessary to use continuous food waste wastewater treatment equipment to treat food waste and its wastewater in order to achieve environmental protection.

[0003] Existing continuous treatment devices for kitchen waste and wastewater generally consist of a tank, a feed pipe, crushing blades, stirring blades, aeration pipes, and a filter screen. In operation, the wastewater enters the tank through the feed pipe, where it is first crushed by the crushing blades. The crushed wastewater then enters the right side of the tank, where it reacts with chemical agents such as acid-base neutralizers and oxidizing-reducing agents. The stirring blades further agitate the mixture to accelerate the reaction and prevent solid waste from clogging the filter screen. Simultaneously, air is introduced into the wastewater through the aeration pipe to promote the activity of aerobic microorganisms and accelerate the decomposition of organic matter. After preliminary chemical treatment, the wastewater is filtered through the filter screen and flows into the lower part of the tank.

[0004] However, in actual use, since the aeration pipe and the stirring blade are usually installed separately, when they operate independently, there may be insufficient oxygen in some areas or uneven distribution of chemical agents, which prolongs the treatment time, thereby not only reducing the treatment efficiency but also increasing the treatment cost. Utility Model Content

[0005] The purpose of this invention is to provide a continuous treatment device for kitchen waste wastewater to solve the problems mentioned in the background art.

[0007] Preferably, a limiting groove is provided on the outside of the air intake pipe, and a receiving groove is provided on the inside of the mounting block. Two mounting rings are slidably connected to the receiving groove. A sealing ring is detachably connected inside the mounting ring, and multiple grooves are provided on the side of the sealing ring away from the mounting ring.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 7This utility model provides a technical solution: a continuous treatment device for kitchen waste wastewater, including a housing 1. A connecting shaft 2 is rotatably connected to the right side of the housing 1. The housing 1 limits the rotation of the connecting shaft 2, allowing it to rotate smoothly. Multiple stirring blades 3 are fixedly connected to the outside of the connecting shaft 2, enabling it to drive the stirring blades 3 to mix the crushed waste and wastewater. A first connecting groove 4 is provided inside the connecting shaft 2, and multiple air outlets 5 are provided on the inner wall of the first connecting groove 4, allowing aeration of the waste and wastewater inside the housing 1 through the first connecting groove 4 and the air outlets 5. A mounting block 6 is rotatably connected to the front of the connecting shaft 2, ensuring it does not affect the rotation of the connecting shaft 2. A second connecting groove 7 is provided inside the mounting block 6, communicating with the first connecting groove 4. An air inlet pipe 8 is inserted into the front of the second connecting groove 7. The other end of the air pipe 8 is connected to an air pump, allowing the gas inside the air pump to enter the interior of the connecting channel 4 through the connecting channel 2 7. A feed pipe is installed on the left side of the box 1, and an exhaust pipe and a dosing pipe are installed on the top of the box 1. The interior of the box 1 is equipped with crushing blades, a filter screen, and other structures. In use, wastewater enters the interior of the box 1 through the feed pipe and is first crushed by the crushing blades. The crushed wastewater slides to the right, allowing the crushed wastewater to react with chemical agents such as acid-base neutralizers and oxidizing-reducing agents. The stirring blades 3 are used to stir the mixture to accelerate the reaction and prevent solid waste from clogging the filter screen. At the same time, air is introduced into the wastewater through the aeration pipe to promote the activity of aerobic microorganisms and accelerate the decomposition of organic matter. After preliminary treatment by chemical agents, the wastewater is filtered through the filter screen and flows into the lower interior of the box 1.

[0025] In use, by inserting the air inlet pipe 8 into the mounting block 6, the air pump at the other end of the air inlet pipe 8 is started, allowing external gas to enter the connecting groove 2 7 through the air inlet pipe 8, and then enter the connecting groove 1 4 through the connecting groove 2 7. The gas then enters the box 1 through the air outlet 5, thereby aerating the crushed wastewater inside the box 1. When used in conjunction with the stirring blades 3, aeration is carried out while stirring, so that air can be evenly released into the wastewater, improving the mixing efficiency of chemical agents, helping to accelerate the decomposition of organic matter, and reducing treatment costs.

[0026] Example 2: Based on Example 1, in order to achieve a more stable connection of the intake pipe 8, a limiting groove 9 is provided on the outside of the intake pipe 8, and a receiving groove 18 is provided on the inside of the mounting block 6. Two mounting rings 10 are slidably connected to the receiving groove 18. The mounting rings 10 are slidably connected inside the limiting groove 9. The limiting groove 9 and the receiving groove 18 limit the mounting rings 10, so that the mounting rings 10 will not deviate when sliding. A sealing ring 11 is detachably connected inside the mounting ring 10, so that the sealing ring 11 can be easily removed. The sealing ring 11 is slidably connected inside the limiting groove 9. The limiting groove 9 limits the sealing ring 11, so that the sealing ring 11 will not deviate when sliding. Multiple grooves 12 are provided on the side of the sealing ring 11 away from the mounting ring 10. The inner wall of the groove 12 fits against the limiting groove 9, so that the sealing ring 11 can deform inside the limiting groove 9, thereby making the inner wall of the groove 12 fit against the limiting groove 9, thus making the connection of the intake pipe 8 more stable.

[0027] After the intake pipe 8 is inserted into the inner part of the connecting groove 7, the mounting ring 10 is moved inward, so that the mounting ring 10 can push the sealing ring 11 into the inner part of the limiting groove 9, thereby causing the sealing ring 11 to deform inside the limiting groove 9, so that the sealing ring 11 and the groove 12 can deform, and the inner wall of the groove 12 can fit with the limiting groove 9, thereby allowing the intake pipe 8 to be installed stably.

[0028] Example 3: Based on Example 2, to facilitate the installation and removal of the intake pipe 8, the mounting block 6 has multiple placement slots 13 inside. A pull rope 14 is slidably connected inside each placement slot 13, limiting the pull rope 14 and preventing it from shifting during sliding. One end of the pull rope 14 is fixedly connected to a placement block 16. One side of the placement block 16 is slidably connected inside the placement slot 13, and the other side of the placement slot 13 is slidably connected inside the storage slot 18. The storage slot 18 and the placement slot 13... The placement block 16 serves as a limit, allowing it to slide smoothly. The end of the placement block 16 away from the pull rope 14 is fixedly connected to the mounting ring 10. The other end of the pull rope 14 is fixedly connected to a pull ring 15. The pull ring 15 is slidably connected to the outside of the mounting block 6. The mounting block 6 serves as a limit for the pull ring 15, allowing it to slide smoothly. An elastic element 17 is sleeved on the outside of the pull rope 14. One end of the elastic element 17 is fixedly connected to the inside of the placement groove 13, and the other end is fixedly connected to the placement block 16.

[0029] When the intake pipe 8 needs to be disassembled, by pulling the pull ring 15 forward or backward, the pull ring 15 pulls the pull rope 14 outward, which in turn pulls the placement block 16 outward. This causes the placement block 16 to compress the elastic element 17, causing it to deform and pull the mounting ring 10 outward. This allows the mounting ring 10 to disengage the sealing ring 11 from the inside of the limiting groove 9, thus freeing the intake pipe 8 from restriction. Conversely, by releasing the pull ring 15, the elastic element 17 returns to its original position, causing the receiving groove 18 to push the placement block 16 inward. This pushes the mounting ring 10 inward, which in turn pushes the sealing ring 11 inward, allowing the mounting ring 10 to push the sealing ring 11 into the inside of the limiting groove 9.

[0030] In actual use, by pulling the pull ring 15 forward or backward, the pull ring 15 pulls the pull rope 14 outward, which in turn pulls the placement block 16 outward. This causes the placement block 16 to compress the elastic element 17, deforming it and pulling the mounting ring 10 outward. The mounting ring 10 then slides into the air intake pipe 8, connecting the air intake pipe 8 to the connecting groove 7. Releasing the pull ring 15 allows the elastic element 17 to reset, causing the receiving groove 18 to push the placement block 16 inward. This pushes the mounting ring 10 inward, which in turn pushes the sealing ring 11 inward, allowing the sealing ring 11 to enter the limiting groove 9. The sealing ring 11 then remains within the limiting groove 9. The deformation causes the sealing ring 11 and the groove 12 to deform, allowing the inner wall of the groove 12 to fit into the limiting groove 9, thus ensuring the stable installation of the air inlet pipe 8. At this time, by rotating the connecting shaft 2, the connecting shaft 2 drives the stirring blade 3 to stir the crushed wastewater on the right side of the box 1, and starts the air pump at the other end of the air inlet pipe 8, allowing external gas to enter the connecting groove 2 7 through the air inlet pipe 8, and then enter the connecting groove 1 4 through the connecting groove 2 7. The gas then enters the box 1 through the air outlet 5, thus aerating the crushed wastewater inside the box 1. In conjunction with the stirring blade 3, aeration is carried out while stirring, allowing air to be evenly released into the wastewater, improving the mixing efficiency of chemical agents, helping to accelerate the decomposition of organic matter, and reducing treatment costs.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
