Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to solid-liquid separation equipment for wastewater recovery. Background Art

[0002] With the rapid development of modern industry and the continuous growth of population, the consumption of water resources is increasing day by day, and the discharge of wastewater is also rising. Industrial production processes, municipal sewage treatment and daily life activities will generate a large amount of wastewater. These wastewaters often contain a variety of pollutants, including suspended solids, organic matter, heavy metals, etc. If they are directly discharged without proper treatment, they will cause serious damage to the ecological environment, such as polluting surface water, soil and groundwater, affecting the survival of aquatic organisms and destroying the balance of the entire ecosystem;

[0003] On the other hand, water shortage has become a serious global problem, and improving the recycling rate of water resources has become one of the key measures to alleviate the tense situation of water resources. Therefore, effective recycling and treatment of wastewater so that it can meet certain usage standards and be reused has important economic and environmental significance, whether it is used as circulating cooling water in industrial production or for municipal purposes such as urban greening and landscape replenishment. Solid-liquid separation is a key link in the wastewater recycling process, and its effect directly affects the feasibility of subsequent treatment processes and whether the final effluent water quality can meet the standards for reuse;

[0004] Most traditional filtration equipment uses static filter screens or filter cloths for filtration. When these devices treat wastewater, solid particles tend to accumulate quickly on the filter screen to form a clogging layer, resulting in increased filtration resistance and a sharp drop in filtration speed. Frequent shutdowns are required for manual cleaning or replacement of the filter screen, which not only increases labor costs and maintenance workload, but also affects the continuity and overall efficiency of wastewater treatment. In addition, static filtration has limited interception effect on solid particles with smaller particle sizes, and it is difficult to achieve high-precision solid-liquid separation, which puts subsequent processing steps under greater pressure and increases processing costs accordingly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The swinging motion of the separation bin is controlled by utilizing the dead weight of the wastewater and the liquid level sensor in coordination with the telescopic cylinder, so that the separation bin performs two-stage filtration of the wastewater with the cooperation of the coarse filter and the fine filter. This dynamic filtration method effectively intercepts solid particles of different sizes, greatly improving the effect and efficiency of separation of solids and liquids, obtaining a purer liquid portion for subsequent treatment or recycling, reducing the potential harm of solid impurity emissions to the environment, and reducing the difficulty and cost of subsequent treatment processes. The reciprocating swing of the separation bin increases the flow path and disturbance of the wastewater in the filter, preventing solid particles from quickly accumulating on the filter to form a clogging layer, ensuring the continuity and stability of the filtration process, reducing the maintenance workload of frequent cleaning or replacement of the filter due to filter clogging, and improving the overall operating reliability and processing capacity of the equipment;

[0019] 2. The buffer system composed of buffer springs and buffer blocks can effectively absorb and disperse impact force when the separation bin swings and the wastewater bin is subjected to external force. This significantly reduces the vibration amplitude and noise level during equipment operation, avoids problems such as loosening, wear, fatigue damage of equipment components caused by excessive vibration, thereby extending the service life of various parts of the equipment, reducing the probability of equipment failure, ensuring the long-term stable operation of the equipment, and reducing the economic cost and downtime loss caused by equipment maintenance and replacement of parts. The stable equipment operation state is conducive to improving the control accuracy and repeatability of the entire wastewater treatment process, ensuring the consistency of the treatment effect of each batch of wastewater, improving the quality and reliability of the treatment process, and helping enterprises or units to better meet the requirements of environmental protection regulations and their own production and operation needs;

[0020] 3. The driving motor drives the stirring frame and multiple stirring rods to stir the liquid or material in the reaction tank. This stirring method can make the substances of different components in the reaction tank fully contact, collide and disperse in three-dimensional space. Whether it is liquids with large density differences or the mixture of solid particles and liquids, a fast and uniform mixing effect can be obtained. When adding chemical agents in wastewater treatment, the agents can be quickly and evenly dispersed in the wastewater, avoiding the situation of excessively high or low local concentrations, so that the chemical reaction can be carried out synchronously and efficiently in the entire reaction tank, greatly improving the uniformity and speed of mixing, thereby improving the treatment efficiency;

[0021] 4. When the driving motor is working, since a synchronous belt is provided between the first synchronous wheel and the second synchronous wheel located below the driving rod, when the first synchronous wheel rotates, the second synchronous wheel is driven to rotate through the transmission action of the synchronous belt, so that the entire driving rod is stably rotated inside the sewage discharge bin, providing a power source for subsequent sewage cleaning actions. As the driving rod rotates, the reciprocating screw rod fixedly connected above it also rotates together, and the threaded sleeve threadedly connected to the reciprocating screw rod will make reciprocating linear motion along the screw rod due to the rotation of the screw rod. The symmetrically arranged protrusions on the surface of the threaded sleeve cooperate with the symmetrically arranged grooves in the driving wheel. In this way, when the threaded sleeve moves to a suitable position, it can drive the driving wheel to move together. Drive racks are provided on both sides of the driving wheel on the mounting plate. When the driving wheel follows the movement of the threaded sleeve, gear meshing transmission will occur between the drive racks. Through this reciprocating linear movement of the scraper, the dirt inside the sewage discharge bin can be scraped and cleaned, thereby achieving the purpose of sewage cleaning.

[0036] A transmission wheel 513 is provided on the side of the rotating rod 509 close to the sector rack 510, and the transmission wheel 513 and the sector rack 510 are meshed with each other. A rotating wheel 517 is provided in the middle of the rotating rod 509, and a telescopic cylinder 515 is fixedly connected to one side of the recovery bin 1, and a telescopic rod 516 is fixedly connected to the output end of the telescopic cylinder 515, and a transmission rack 518 is fixedly connected to the side of the telescopic rod 516 away from the telescopic cylinder 515, and the gears between the transmission rack 518 and the rotating wheel 517 are meshed with each other;

[0037] A limiter 514 is provided between the rotating rod 509 and the movable shaft 512, a fixed plate 507 is fixedly connected to one side of the sector rack 510, a separation chamber 504 is fixedly connected below the fixed plate 507, a coarse filter 505 is provided on the separation chamber 504, and a fine filter 506 is provided below the coarse filter 505;

The wastewater bin 501 is provided with a buffer block 521 in the buffer groove 519, and a buffer spring 520 is provided on the buffer groove 519 between the buffer block 521 and the recovery bin 1;

[0039] When using the device, firstly, waste water is poured into the waste water tank 501. Due to the weight of the waste water itself, the transmission rack 518 and the rotating wheel 517 in the middle of the rotating rod 509 are meshed with each other, thereby driving the rotating rod 509 to rotate around the fixed block 508. The transmission wheel 513 arranged on the side of the rotating rod 509 close to the fan-shaped rack 510 is meshed with the fan-shaped rack 510. When the rotating rod 509 rotates, the fan-shaped rack 510 is driven to swing around the movable shaft 512 through the transmission wheel 513.

[0040] At the same time, if the water in the reaction tank reaches the liquid level sensor 13, the liquid level sensor 13 will transmit a signal to the telescopic cylinder 515, and the telescopic cylinder 515 on one side of the recovery bin 1 will start to work, and the telescopic rod 516 at its output end will perform a telescopic movement. The telescopic movement of the telescopic rod 516 drives the transmission rack 518 fixedly connected thereto to move, and the transmission rack 518 is meshed with the rotating wheel 517 in the middle of the rotating rod 509, thereby driving the rotating rod 509 to rotate around the fixed block 508. The transmission wheel 513 arranged on the side of the rotating rod 509 close to the fan-shaped rack 510 is meshed with the fan-shaped rack 510.

Therefore, the swing of the sector rack 510 will drive the separation bin 504 to swing back and forth with the movable shaft 512 as the axis. A coarse filter 505 and a fine filter 506 are arranged on the separation bin 504. After the wastewater enters the separation bin 504 from the wastewater bin 501, during the reciprocating swing of the separation bin 504, the solid particles in the wastewater are first intercepted by the coarse filter 505, and the larger particles of solids remain on the coarse filter 505, while the smaller particles of solids and liquids continue to pass through the coarse filter 505, and then are further filtered through the fine filter 506, so that the solids and liquids are more fully separated.

[0042] Example 2

[0043] Reference Figure 7 , this embodiment is based on the previous embodiment, and is different from the previous embodiment in that the mixing mechanism 8 includes a driving motor 801, a driving rod 802, a stirring frame 803, a fixed frame 804 and a stirring rod 805, a driving motor 801 is arranged at the bottom of the recovery bin 1, and a fixed frame 804 is arranged inside the reaction tank 7, a driving rod 802 is movably connected to the middle of the fixed frame 804, the output end of the driving motor 801 is fixedly connected to the driving rod 802, and a stirring frame 803 is arranged on the driving rod 802, and a plurality of stirring rods 805 are arranged at equal distances on the stirring frame 803;

[0044] A liquid level tank 12 is provided on one side of the reaction tank 7, a liquid level tube 10 is provided inside the liquid level tank, a liquid level sensor 13 is provided on the upper side of the liquid level tube, and a signal connection is provided between the liquid level sensor 13 and the telescopic cylinder 515;

[0045] A sewage pipe 4 is embedded in one side of the recovery bin 1 and the sewage bin 2, and a solenoid valve is provided on the sewage pipe 4;

[0046] The driving motor 801 starts to operate after being powered on, and its output end drives the driving rod 802 to rotate, and the stirring frame 803 on the driving rod 802 and the multiple stirring rods 805 set at equal distances rotate synchronously. During the stirring process, the stirring rod 805 fully stirs the liquid or material in the reaction tank 7, so that the liquids or materials of different components are mixed evenly, thereby improving the mixing effect and reaction efficiency. The liquid level sensor is connected to the telescopic cylinder signal. The liquid level sensor 13 usually works on the principle of magnetostriction. When the liquid level changes, the measuring element in the liquid level sensor 13 will produce a corresponding signal change. When the liquid level reaches the set threshold, the liquid level sensor 13 will transmit the signal to the control of the telescopic cylinder 515. The control system controls the telescopic rod 516 of the telescopic cylinder 515 to perform telescopic movement according to the received signal, driving the separation chamber 504 to perform corresponding actions to achieve separation and treatment of wastewater. The solenoid valve on the sewage pipe and the solenoid valve sewage pipe 4 is based on electromagnetic induction. When sewage needs to be discharged, the control system sends an opening signal to the solenoid valve, so that the electromagnet inside the solenoid valve is energized to generate a magnetic field, attracting the valve to open it. At this time, the wastewater or other liquid in the recovery chamber 1 or the sewage bin 2 can flow into the downstream pipeline through the sewage pipe 4 for discharge. When sewage is not needed, the control system cuts off the current of the electromagnet, the magnetic field disappears, and the valve automatically closes under the action of spring force or its own gravity, thereby preventing the flow of liquid.

[0051] When the driving motor 801 is working, since a synchronous belt 902 is sleeved between the first synchronous wheel 901 and the second synchronous wheel 911 located below the driving rod 910, when the first synchronous wheel 901 rotates, the second synchronous wheel 911 is driven to rotate through the transmission effect of the synchronous belt 902, so that the entire driving rod 910 can be stably rotated inside the sewage discharge bin 2, providing a power source for subsequent sewage cleaning actions.
