Description

Technical Field

[0001] This application relates to the technical field of industrial wastewater treatment equipment, and in particular to a filtration device for industrial wastewater. Background Technology

[0002] Industrial wastewater refers to wastewater and waste liquid discharged during industrial production processes. It contains industrial raw materials, intermediate products, by-products, and pollutants generated during production that are lost with the wastewater. Industrial wastewater is diverse and complex in composition. If discharged directly without effective treatment, it can cause serious harm to the environment.

[0003] Currently, wastewater filtration equipment is commonly used to treat industrial wastewater. However, the cleaning process of existing wastewater filtration equipment is complex, and the filter media is inconvenient to replace and clean. It requires professional equipment and technicians to operate. Failure to replace the filter media or clean the wastewater filtration equipment in a timely manner will lead to a decrease in the filtration effect on industrial wastewater.

[0004] The aforementioned technologies suffer from drawbacks such as difficulty in replacing filter media, challenges in cleaning the equipment, and a decline in the filtration efficiency for industrial wastewater. Utility Model Content

[0005] To facilitate equipment cleaning and filter media replacement, thereby improving the filtration effect of the device, this application provides a filtration device for industrial wastewater.

[0006] This application provides a filtration device for industrial wastewater, which adopts the following technical solution:

[0007] A filtration device for industrial wastewater, comprising:

[0008] A reaction vessel, wherein a water inlet pipe is connected to the top of the reaction vessel and a water outlet pipe is connected to the bottom of the side wall of the reaction vessel;

[0009] A stirring assembly is installed on the reaction vessel, and the stirring assembly is used to stir the solution in the reaction vessel evenly.

[0010] A cleaning component is installed inside the reaction vessel and is used to scrape off sediment from the inner wall of the reaction vessel.

[0011] A collection component is installed inside the reaction vessel and is used to collect precipitates inside the reaction vessel;

[0012] A feeding pipe is provided at the top of the reaction vessel and is connected to the reaction vessel.

[0013] By adopting the above technical solution, wastewater enters the reaction tank, and treatment agents are added to the feeding pipe. The stirring component stirs the solution in the reaction tank evenly, ensuring that the wastewater and treatment agents are fully mixed, making the chemical reaction more complete and helping to improve the filtration effect. The cleaning component scrapes off the sediment on the inner wall of the reaction tank during the stirring process, preventing the sediment from adhering to the tank wall and affecting the filtration effect. The slidable and detachable collection component can periodically collect the sediment scraped off by the cleaning component and the sediment generated during the reaction process, improving the cleaning effect of the equipment.

[0014] Optionally, the stirring assembly includes:

[0015] An electric motor, the fixed end of which is fixedly mounted on the reaction vessel;

[0016] A rotating shaft is inserted inside the reaction vessel, and one end of the rotating shaft is fixedly connected to the output end of the motor.

[0017] A stirring fan blade, wherein there are no fewer than two stirring fan blades, and the stirring fan blades are fixedly installed on the rotating shaft.

[0018] By adopting the above technical solution, the motor drives the rotating shaft to rotate, which in turn drives the stirring fan blades to rotate, stirring the wastewater and treatment agents in the reaction tank, accelerating the reaction speed, improving the wastewater treatment efficiency, enhancing the filtration effect on industrial wastewater, and achieving efficient wastewater treatment.

[0019] Optionally, the cleaning component includes:

[0020] Two fixing rods, one end of each fixing rod being fixedly installed on the rotating shaft;

[0021] An inner wall scraper is fixedly installed at the end of the two fixed rods away from the rotating shaft, and the inner wall scraper abuts against the inner wall of the reaction cylinder.

[0022] By adopting the above technical solution, when the rotating shaft rotates, the fixed rod drives the inner wall scraper to rotate along the inner wall of the reaction cylinder. The inner wall scraper abuts against the inner wall of the reaction tank, effectively scraping away impurities and sediments attached to the inner wall. The cleaning component can operate synchronously with the stirring component, without the need for additional power units and control systems. This saves costs, improves the cleaning effect, and avoids the impact of local sediment residue on the wastewater treatment effect.

[0023] Optionally, the collection component includes:

[0024] A collection frame is slidably installed inside the reaction vessel and is located below the cleaning assembly;

[0025] A filter screen, which is fixedly installed inside the collection frame;

[0026] A limiting block is fixedly installed on the collection frame, and a corresponding limiting slot is provided on the reaction vessel.

[0027] By adopting the above technical solution, the collection frame provides a centralized collection space for sediment. During the wastewater treatment process, the sediment will naturally sink into the collection frame, which facilitates subsequent cleaning and treatment. The combination of the limiting block and the limiting slot makes the installation of the collection frame in the reaction tank more stable and reliable. The sliding installation method greatly reduces the difficulty and workload of cleaning the filter screen and improves work efficiency.

[0028] Optionally, the preprocessing component includes:

[0029] A pretreatment tank is threadedly connected to the water inlet and is connected to the reaction tank.

[0030] A grille is fixedly installed inside the pretreatment box.

[0031] By adopting the above technical solution, the wastewater passes through a pretreatment tank before entering the reaction tank. The bar screen can effectively intercept larger particles of impurities in the wastewater. By initially filtering large particles of impurities, the burden on subsequent treatment stages in the reaction tank can be reduced, thereby reducing the risk of blockage and improving the treatment efficiency and service life of the equipment.

[0032] Optionally, the water outlet pipe is connected to a filter assembly, the filter assembly comprising:

[0033] A filter box, one end of which is connected to the water outlet pipe, and a water outlet is provided at the end of the filter box away from the water outlet pipe. The filter box is provided with multiple mounting slots.

[0034] A filter layer, which corresponds one-to-one with the mounting groove, and the filter layer is slidably installed in the mounting groove.

[0035] By adopting the above technical solution, the wastewater treated by the reaction tank enters the filter box of the filter assembly from the outlet. The three filter layers in the filter box can filter the wastewater again, remove residual fine impurities and pollutants, further improve the filtration accuracy, and ensure that the treated wastewater meets higher water quality standards. The installation and disassembly of the filter layers are very convenient, making it easier to clean or replace the filter layers and improve the operating efficiency of the equipment.

[0036] Optionally, an observation window is fixedly installed on the side wall of the reaction vessel.

[0037] By adopting the above technical solution, the observation window allows for timely inspection of the reaction tank, enabling the timely detection and handling of potential problems. The observation window provides an intuitive view, allowing operators to observe the wastewater treatment process in the reaction tank in real time, including changes in wastewater color, sediment formation, and stirring effects, thereby improving the reliability and stability of the equipment.

[0038] Optionally, handles are installed on both the collection frame and the filter layer.

[0039] By adopting the above technical solution, the handle allows operators to easily remove the collection frame from the reaction vessel to clean the precipitate and maintain the collection frame. The filter layer can also be removed from the installation slot of the filter box for cleaning or replacement. The operation can be completed conveniently without the need for other tools, thus improving work efficiency.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. By setting up cleaning and stirring components, the wastewater and treatment agents are fully mixed, the chemical reaction is more complete, which helps to improve the filtration effect. During the stirring process, the equipment also scrapes off the sediment on the inner wall of the reaction tank to prevent the sediment from adhering to the tank wall and affecting the filtration effect, prevent the filter screen from clogging, and improve the cleaning efficiency of the device.

[0042] 2. By setting up a collection component, the sediment will naturally sink into the collection box during the wastewater treatment process, which facilitates subsequent cleaning and treatment and improves work efficiency;

[0043] 3. By setting up a filtration component, the wastewater is filtered again to remove residual fine impurities and pollutants, further improving the filtration accuracy and the operating efficiency of the equipment. Attached Figure Description

[0052] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0053] This application discloses a filtration device for industrial wastewater.

[0054] Reference Figure 1The filtration device for industrial wastewater includes a reaction tank 1, a pretreatment component 2, a stirring component 3, a cleaning component 4, a collection component 5, and a filter component 6. The stirring component 3 is installed on the reaction tank 1 and is used to uniformly stir the solution within the reaction tank 1. The cleaning component 4 is installed inside the reaction tank 1 and is used to scrape away sediment from the inner wall of the reaction tank 1. The collection component 5 is installed inside the reaction tank 1 and is used to collect sediment within the reaction tank 1. The pretreatment component 2 is installed on the reaction tank 1 and is used for preliminary filtration of large particulate impurities in the wastewater. The filter component 6 is connected to the reaction tank 1 and is used for further filtration of the wastewater.

[0055] In operation, industrial wastewater first enters the pretreatment component 2 for preliminary filtration of large particulate impurities. After pretreatment, the wastewater enters the reaction tank 1. The stirring component 3 mixes the wastewater and treatment agents in the reaction tank 1 evenly. At the same time, the cleaning component 4 scrapes off the sediment on the inner wall of the reaction tank 1 to prevent the accumulation of impurities from affecting the filtration effect and equipment life. The sediment falls into the collection component 5 for subsequent collection and cleaning. After reaction and preliminary sedimentation, the wastewater flows out of the reaction tank 1 and enters the filtration component 6 for further fine filtration, removing residual small particles and dissolved substances from the wastewater, thus achieving efficient filtration and treatment of industrial wastewater.

[0056] Reference Figure 1 The reaction vessel 1 is cylindrical and vertically arranged. The top is connected to a water inlet pipe 11, the bottom of the side wall of the reaction vessel 1 is connected to a water outlet pipe 12, the top of the reaction vessel 1 is also equipped with a feeding pipe 7, and an observation window 8 is fixedly installed on the side wall of the reaction vessel 1.

[0057] Reference Figure 1 and Figure 2 The pretreatment component 2 includes a pretreatment box 21 and a grid 22. The pretreatment box 21 has a top-opening structure and is a cylindrical shape with an open top. The pretreatment box 21 is threaded to the end of the water inlet pipe 11 away from the reaction tank and is connected to the reaction tank 1. The grid 22 is horizontally set and fixedly installed inside the pretreatment box 21.

[0058] During use, industrial wastewater first flows to the pretreatment tank 21. When the wastewater flows through the screen 22, the screen 22 performs preliminary filtration of large particulate impurities in the wastewater to prevent large particulate impurities from damaging the cleaning and stirring components 3, the collection components 5, and the filter components 6 in the subsequent reaction tank 1, thus ensuring the normal operation of the entire filtration device. After too many large particulate impurities accumulate on the screen 22, the screen 22 should be cleaned or replaced in time to ensure the pretreatment effect.

[0059] Reference Figure 1 and Figure 2The stirring assembly 3 includes a motor 31, a rotating shaft 32, and four stirring blades 33. The cleaning assembly 4 includes two fixed rods 41 and an inner wall scraper 42. The fixed end of the motor 31 is fixedly mounted on the reaction vessel 1, and the rotating shaft 32 passes through the reaction vessel, with one end of the rotating shaft 32 fixedly connected to the output end of the motor 31.

[0060] Four stirring blades 33 are fixedly installed on the rotating shaft 32. The four stirring blades 33 are arranged circumferentially around the axis of the rotating shaft 32. One end of each of the two fixing rods 41 is fixedly installed on the rotating shaft 32. Both fixing rods 41 are perpendicular to the rotating shaft 32. The ends of the two fixing rods 41 away from the rotating shaft 32 are fixedly installed to the inner wall scraper 42. The inner wall scraper 42 is vertically set and abuts against the inner wall of the reaction cylinder.

[0061] When industrial wastewater enters the reaction tank 1, the motor 31 is started and the treatment agent is added to the feed pipe 7. The motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the four stirring blades 33 to start rotating around the rotating shaft 32, so as to fully mix the wastewater and treatment agent in the reaction tank 1. The reaction situation in the reaction tank 1 can be observed in real time through the observation window 8. During the rotation of the rotating shaft 32, the fixed rod 41 is also rotated, which drives the inner wall scraper 42 to scrape off the sediment attached to the inner wall of the reaction tank 1, preventing the accumulation of impurities and improving the cleaning effect and filtration efficiency of the device.

[0062] Reference Figure 2 and Figure 3 The collection component 5 includes a collection frame 51, a filter screen 52, a limiting block 53, and a limiting slot 54. The collection frame 51 is horizontally positioned and slidably installed inside the reaction vessel 1. The limiting block 53 is fixedly installed on the collection frame 51, and the corresponding limiting slot 54 is provided on the reaction vessel 1. The collection frame 51 slides on the reaction vessel 1 through the cooperation of the limiting block 53 and the slot. The filter screen 52 is fixedly installed inside the collection frame 51, and a handle 9 is fixedly installed on the collection frame 51.

[0063] During use, when wastewater reacts in the reaction tank 1, the sediment in the wastewater gradually sinks under the action of gravity. The filter screen 52 can block the sediment, keeping it in the collection frame 51, while the wastewater can flow through the filter screen 52 to the outlet. When the sediment in the collection frame 51 accumulates to a certain extent, the collection frame 51 can be removed from the reaction tank 1 along its sliding direction for cleaning or replacement. After cleaning and maintenance, the collection frame 51 is reinstalled back into the reaction tank 1 to continue the wastewater treatment process. The limiting block 53 restricts the position of the collection frame 51 in the reaction tank 1, preventing excessive displacement of the collection frame 51 under the action of wastewater flow or other external forces. The sealing strip can effectively prevent wastewater from leaking from the gap between the collection frame 51 and the reaction tank 1, ensuring the sealing and stability of the filtration device, enabling the device to efficiently collect sediment and improving the filtration efficiency of the device.

[0064] Reference Figure 1 and Figure 2 The filter assembly 6 includes a filter box 61 and three filter layers 62. The filter box 61 is rectangular. One end of the filter box 61 is connected to the water outlet pipe 12. The end of the filter box 61 away from the water outlet pipe 12 has a water outlet. The filter box 61 has three mounting slots. The filter layers 62 correspond to the mounting slots one by one. The filter layers 62 are slidably installed in the mounting slots. The sliding direction is the height direction of the filter box 61. Each of the three filter layers 62 has a handle 9 fixedly installed on it.

[0065] During operation, the wastewater treated by the reaction tank 1 flows out from the outlet of the reaction tank 1 and enters the filter box 61 of the filter assembly 6. It passes through three sets of filter layers 62 in sequence, with the filter mesh size of the filter layers 62 gradually becoming finer. Different filter layers 62 can remove different types of pollutants. The synergistic effect of the three sets of filter layers 62 can effectively improve the filtration effect of the wastewater. As the filtration work progresses, pollutants will gradually accumulate on the filter layers 62. When it is necessary to clean or replace the filter layers 62, the operator can pull the filter layers 62 out of the installation slot through the handle 9 for replacement, making the operation more convenient and improving the working efficiency of the device.

[0066] The implementation principle of a filtration device for industrial wastewater according to an embodiment of this application is as follows: When in use, the industrial wastewater first enters the pretreatment component 2, and the grid 22 in the pretreatment tank 21 performs preliminary filtration of large particulate impurities in the wastewater.

[0067] Pretreated wastewater flows into reaction tank 1 through the inlet. The stirring assembly 3 operates, and the motor 31 drives the rotating shaft 32 to rotate, thereby causing the four stirring blades 33 to rotate, mixing the wastewater and treatment agent evenly and improving the wastewater treatment efficiency. At the same time, the motor 31 drives the inner wall scraper 42 to rotate, scraping off the sediment on the inner wall of reaction tank 1. The sediment generated during the reaction falls into the collection frame 51 for centralized treatment, while the treated wastewater enters the filter box 61 through the filter screen 52. The wastewater is further finely filtered through three sets of filter layers 62. The filter layers 62 are slidably installed in the mounting groove of the filter box 61 for easy cleaning and replacement, improving the cleaning efficiency of the device and increasing its service life.

[0068] 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.
