Description

Technical Field

[0001] This utility model relates to the field of micro-electrolysis technology, specifically to a micro-electrolysis treatment device for low-concentration COD wastewater. Background Technology

[0002] In the micro-electrolysis treatment process of low-concentration COD wastewater, the reaction tank usually needs to be vented with air or oxygen through an aeration device to maintain the dissolved oxygen environment required for the micro-electrolysis reaction and promote the flow and mixing of wastewater. However, the aeration process will significantly aggravate the turbulent movement of the tank water, causing the packing box suspended in the tank to be subjected to the impact force of the water flow. In the existing technology, the packing box is mostly directly fixed to the top of the reaction tank by slings, lacking a buffer structure or limiting device. When the high-speed water flow impacts the packing box, the box will shake or shift due to uneven force, and its edges or protruding parts will collide hard with the inner wall of the reaction tank, aeration pipes and other components. Therefore, it is necessary to design a micro-electrolysis treatment device for low-concentration COD wastewater to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a micro-electrolysis treatment device for low-concentration COD wastewater to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a micro-electrolysis treatment device for low-concentration COD wastewater, comprising a micro-electrolysis reaction tank and a storage component disposed in its inner cavity, wherein the storage component is used to store micro-electrolysis packing material, and four sets of lifting rings arranged in a rectangular pattern are installed at the top of the storage component for hoisting the storage component;

[0005] Two sets of buffers are installed on both sides of the storage component along its length. The buffers are used to counteract the swaying energy generated by the water flow and limit the displacement of the storage component.

[0006] The two sets of buffer components on the same side are linked by a pin structure, which is configured as a quick-release elastic limiting component, enabling quick assembly and disassembly of the two sets of buffer components.

[0007] Preferably, the pin structure includes a card holder, a card block, a sliding sleeve, and a first spring. The inner wall of the micro-electrolysis reaction cell is equipped with a card holder adapted to the buffer component. The card block can penetrate the card holder and be inserted into the buffer component to lock it. The other ends of the two sets of card blocks are slidably embedded in the inner cavity of the sliding sleeve. The inner cavity of the sliding sleeve is equipped with a first spring to maintain the locked state of the card block through elastic force.

[0008] Preferably, the end of the card block that is inserted into the sliding sleeve has a first card slot, and the sliding sleeve has a second card slot corresponding to the first card slot.

[0009] Preferably, the buffer includes a damping telescopic seat and a second spring. One end of the damping telescopic seat is welded to the storage component, and the other end is connected to the pin structure. The second spring is sleeved on its exterior.

[0010] Preferably, the storage component includes a box body, a box cover, and bolts. The top of the box body has four sets of lifting rings arranged in a rectangle. The top of the box body can be closed by the box cover. The box cover and the box body are connected by bolts. Both the box body and the box cover have several sets of water passage holes. The water passage holes are distributed in a honeycomb pattern to ensure sufficient contact between wastewater and packing material.

[0011] Preferably, an aeration pipe is installed on one side of the micro-electrolysis reaction cell at a position below the storage component.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The buffer component of this invention effectively counteracts the impact energy of water flow, limits the displacement of the storage components, reduces swaying or displacement caused by uneven force on the storage components, and prevents hard collisions between its edges or protruding parts and components such as the inner wall of the reaction tank and aeration pipes. This improves the stability and safety of the device, extends the service life of each component, and the pin structure, as a quick-release elastic limiting component, enables the rapid disassembly and assembly of two sets of buffer components on the same side. This facilitates the installation, debugging, maintenance, and replacement of the storage components and buffer components, improves the maintainability and ease of operation of the device, and is beneficial to the daily operation and management of the device.

[0014] This utility model features a damping telescopic seat that works in conjunction with a second spring. Through a dual mechanism of mechanical damping to dissipate impact kinetic energy and spring elastic buffering, it effectively reduces the swaying amplitude of the stored components, preventing hard collisions with the pool wall and pipes, and improving the operational stability of the device. The first spring maintains the locking state of the latch, ensuring a reliable connection between the buffer component and the pool wall. By pulling the first slot, the second slot's structural design allows for quick unlocking of the latch, enabling the buffer component to be disassembled and assembled without tools, significantly shortening maintenance time and improving operational efficiency.

[0015] This utility model's cover is connected to the box body with bolts, facilitating quick disassembly and replacement of the packing material. Maintenance does not require the entire storage unit to be hoisted. The enclosed structure prevents packing material loss, and the honeycomb distribution of the water passages increases the water flow area, reduces water flow resistance, and maximizes the contact area between wastewater and the packing material. The aeration pipe is located below the storage unit, allowing airflow to directly impact the wastewater at the bottom of the packing material, avoiding aeration dead zones caused by box obstruction and improving dissolved oxygen utilization. As the bubbles rise, they carry wastewater through the water passages, forming a bidirectional flow field of "downward and upward rushing," enhancing the contact frequency and mixing effect between wastewater and the packing material, and optimizing the micro-electrolysis reaction conditions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please refer to Figure 1-4 As shown, this utility model provides a micro-electrolysis treatment device for low-concentration COD wastewater, including a micro-electrolysis reaction tank 1 and a storage component disposed in its inner cavity. The storage component is used to store micro-electrolysis packing material, and four sets of lifting rings 2 arranged in a rectangular pattern are installed on the top of the storage component for hoisting the storage component.

[0023] Two sets of buffers are installed on both sides of the storage unit along its length. The buffers are used to counteract the swaying energy generated by the water flow and limit the displacement of the storage unit.

[0024] The two sets of buffer components on the same side are linked by a pin structure. The pin structure is configured as a quick-release elastic limiting component, which enables the quick assembly and disassembly of the two sets of buffer components.

[0025] The storage unit inside the micro-electrolysis reaction tank 1 is suspended in the tank by four sets of lifting rings 2 arranged in a rectangular shape at the top, in conjunction with the existing lifting structure. It is used to store micro-electrolysis packing for micro-electrolysis treatment of low-concentration COD wastewater. When the aeration device introduces air or oxygen into the tank, it intensifies the turbulent movement of the tank water. When the water flow impacts the storage unit, the buffers on both sides of the storage unit along the length direction play a role in counteracting the swaying energy generated by the water flow impact, thereby limiting the displacement amplitude of the storage unit and reducing its swaying. The two sets of buffers on the same side are linked by a quick-release elastic limit component pin structure. When it is necessary to install, disassemble or maintain the storage unit, the two sets of buffers can be quickly disassembled and assembled, which is convenient for operation.

[0026] The buffer components effectively counteract the impact energy of water flow, limit the displacement of the storage components, reduce swaying or displacement caused by uneven force, and prevent hard collisions between their edges or protruding parts and components such as the inner wall of the reaction tank and aeration pipes. This improves the stability and safety of the device and extends the service life of each component. The pin structure, as a quick-release elastic limiting component, enables the rapid disassembly and assembly of two sets of buffer components on the same side. This facilitates the installation, debugging, maintenance, and replacement of the storage components and buffer components, improving the maintainability and ease of operation of the device and benefiting its daily operation and management.

[0027] Specifically, the latch structure includes a latch 3, a latch 4, a sliding sleeve 5, and a first spring 6. The inner wall of the micro-electrolysis reaction cell 1 is equipped with a latch 3 that is compatible with the buffer. The latch 4 can penetrate the latch 3 and be inserted into the buffer to lock it. The other ends of the two sets of latches 4 are slidably embedded in the inner cavity of the sliding sleeve 5. The inner cavity of the sliding sleeve 5 is equipped with a first spring 6, which maintains the locked state of the latch 4 through elastic force. The end of the latch 4 inserted into the sliding sleeve 5 has a first slot 7, and the sliding sleeve 5 has a second slot 8 corresponding to the first slot 7. The buffer includes a damping telescopic seat 9 and a second spring 10. One end of the damping telescopic seat 9 is welded to the storage component, and the other end is connected to the latch structure. The second spring 10 is sleeved on its outside.

[0028] The locking block 4 penetrates the locking seat 3 and inserts into the damping telescopic seat 9 of the buffer component. It cooperates with the first spring 6 inside the sliding sleeve 5. The elastic force of the spring keeps the locking block 4 in a locked state, fixing the two sets of buffer components on the same side to the locking seat 3 on the inner wall of the reaction tank, restricting the lateral displacement of the storage component. When the water flow impacts the storage component, the damping telescopic seat 9 is compressed and contracts, and the externally sleeved second spring 10 is compressed synchronously. The impact energy is absorbed through the damping structure and the elastic deformation of the spring, and the shaking of the storage component is counteracted. After the impact weakens, the second spring 10 resets and pushes the damping telescopic seat 9 to extend, so that the storage component returns to its initial position. When the storage component needs to be removed, the locking block 4 is pulled to expose the first locking groove 7 of the sliding sleeve 5. Because the sliding sleeve has a second locking groove 8, the first locking groove 7 is exposed to form a pull ring, which overcomes the elastic force of the first spring 6 and slides the locking block 4 into the sliding sleeve 5 until the locking block 4 is separated from the locking seat 3 and the buffer component, realizing the rapid separation of the two sets of buffer components.

[0029] The damping telescopic seat 9 works in conjunction with the second spring 10 to effectively reduce the swaying amplitude of the stored components through a dual mechanism of mechanical damping to consume impact kinetic energy and spring elastic buffering, avoiding hard collisions with the pool wall and pipes, and improving the operational stability of the device. The first spring 6 maintains the locking state of the locking block 4 to ensure reliable connection between the buffer component and the pool wall. By pulling the first locking groove 7, the locking block 4 can be quickly unlocked using the structural design of the second locking groove 8, allowing the buffer component to be disassembled and assembled without tools, greatly shortening maintenance time and improving operational efficiency.

[0030] The storage unit includes a box body 11, a box cover 12, and bolts 13. The top of the box body 11 has four sets of lifting rings 2 arranged in a rectangle. The top of the box body 11 can be closed by the box cover 12. The box cover 12 is connected to the box body 11 by bolts 13. Both the box body 11 and the box cover 12 are provided with several sets of water passage holes 14. The water passage holes 14 are arranged in a honeycomb pattern to ensure full contact between wastewater and packing material. An aeration pipe 15 is installed on one side of the micro-electrolysis reaction tank 1 at a position below the storage unit.

[0031] The micro-electrolysis packing is loaded inside the tank 11, and the tank cover 12 is fixed and sealed to the tank 11 by bolts 13 to form a closed storage space. The honeycomb-shaped water passages 14 of the tank 11 and the tank cover 12 allow wastewater to pass evenly through the packing layer, ensuring that the wastewater and the packing are in full contact and that the micro-electrolysis reaction is carried out efficiently to degrade COD. The aeration pipe 15 is installed below the storage unit, and the air or oxygen introduced forms a bubble flow that passes through the packing layer and wastewater from bottom to top. Since the aeration pipe is lower than the storage unit, the upward path of the airflow is not blocked by the tank 11 and directly acts on the bottom of the packing and the surrounding wastewater, enhancing the turbulent mixing in the tank. At the same time, the buoyancy of the bubbles drives the wastewater to flow upward, forming convection with the water flow in the water passages 14, further improving the mass transfer efficiency.

[0032] The cover 12 is connected to the body 11 by bolts 13, which facilitates quick disassembly and replacement of the packing. During maintenance, there is no need to hoist the entire storage unit. The closed structure prevents the packing from being lost, and the honeycomb distribution of the water holes 14 increases the water flow area, reduces water flow resistance, and ensures that the contact area between wastewater and packing is maximized. The aeration pipe 15 is located below the storage unit, and the airflow directly impacts the wastewater at the bottom of the packing, avoiding the aeration dead zone caused by the obstruction of the body 11, improving the dissolved oxygen utilization rate. During the rise of the bubbles, the wastewater is carried through the water holes 14, forming a two-way flow field of "downward rushing and upward surging", which enhances the contact frequency and mixing effect between wastewater and packing, and optimizes the micro-electrolysis reaction conditions.

[0033] Working principle: The locking block 4 penetrates the locking seat 3 and inserts into the damping telescopic seat 9 of the buffer component. It cooperates with the first spring 6 inside the sliding sleeve 5. The elastic force of the spring keeps the locking block 4 in a locked state, fixing the two sets of buffer components on the same side to the locking seat 3 on the inner wall of the reaction tank, restricting the lateral displacement of the storage component. When the water flow impacts the storage component, the damping telescopic seat 9 is compressed and contracts, and the externally sleeved second spring 10 is compressed synchronously. The impact energy is absorbed through the damping structure and the elastic deformation of the spring, and the shaking of the storage component is counteracted. After the impact weakens, the second spring 10 returns to its original position and pushes the damping telescopic seat 9 to extend, so that the storage component returns to its initial position. When the storage component needs to be removed, the locking block 4 is pulled to expose the first locking groove 7 of the sliding sleeve 5. Because the sliding sleeve has a second locking groove 8, the first locking groove 7 is exposed to form a pull ring, which overcomes the elastic force of the first spring 6 and slides the locking block 4 into the sliding sleeve 5. Until the card block 4 disengages from the card seat 3 and the buffer, the two sets of buffers are quickly separated. The micro-electrolysis packing is loaded into the box 11, and the box cover 12 is fixed and sealed to the box 11 by bolts 13 to form a closed storage space. The honeycomb water passage holes 14 of the box 11 and the box cover 12 allow the wastewater to pass through the packing layer evenly, ensuring that the wastewater and the packing are in full contact and efficiently carry out micro-electrolysis reaction to degrade COD. The aeration pipe 15 is installed below the storage component. The air or oxygen introduced forms a bubble flow that passes through the packing layer and wastewater from bottom to top. Since the aeration pipe is lower than the storage component, the upward path of the airflow is not blocked by the box 11 and directly acts on the bottom of the packing and the surrounding wastewater, enhancing the turbulent mixing in the pool. At the same time, the buoyancy of the bubbles drives the wastewater to flow upward, forming convection with the water flow in the water passage holes 14, further improving the mass transfer efficiency.
