Description

Technical Field

[0001] This invention relates to the field of textile wastewater treatment technology, and in particular to a filtration device for textile wastewater treatment. Background Technology

[0002] With the rapid development of the textile industry, the amount of wastewater discharged during its production process is also increasing. Textile wastewater mainly originates from dyeing and finishing processes, and is characterized by large volume and complex composition. This wastewater typically contains suspended solids, grease, fiber debris, surfactants, dyes, and various organic pollutants. If discharged directly without treatment, it will cause serious pollution to the soil, water bodies, and other ecological environments, threatening the survival of surrounding plants and animals and human health. However, the fiber debris and other substances contained in textile wastewater have certain recycling value. Effective separation and recycling of these materials can not only reduce environmental pollution but also achieve resource recycling and reduce production costs.

[0003] Application number CN202020500483.2 discloses a textile wastewater treatment device with a filtration mechanism, including a device body, a cleaning mechanism, a treatment mechanism, and a flocculant storage tank. The device body has a protective door on its exterior. A control panel is fixedly mounted to one end of the device body with screws, and a microcontroller is embedded inside the control panel. An electrolysis tank is fixedly mounted to one end of the device body's interior, and a circulation tank is fixedly mounted to one side of the bottom of the electrolysis tank. A treatment tank is fixedly mounted to one side of the circulation tank, and a filter tank is fixedly mounted to one side of the electrolysis tank. This invention filters large molecules through water entering a quartz sand filter plate, adsorbs odors through an activated carbon plate, and removes small molecules through anthracite filter plates. When water enters a disinfection tank, a first pump is activated, drawing disinfectant from the disinfectant storage tank into the disinfection tank for disinfection, achieving a good filtration effect.

[0004] Application number CN201811588899.8 discloses a textile wastewater filter, including a filter cartridge and a biological reactor. The filter cartridge includes a cylinder body, a cover, and a support. The cover is installed on the top of the cylinder body. A rotating disk is installed on the inner side wall of the bottom of the cylinder body, and an agitation mechanism is installed on the rotating disk. A screw and a filter screen are installed inside the cylinder body, and the filter screen is fixedly installed below the screw. The biological reactor includes a filter cake device and a reactor body. The filter cake device includes a mounting frame and a filtration structure. The filtration structure includes a cylinder, a connecting plate, and a filter box. The filter box has an open end facing the left side of the reactor body. The purpose is to provide a filter for treating lightly polluted wastewater, removing solid impurities and organic pollutants from the wastewater in two stages, reducing the turbidity of the wastewater, enabling the effluent to meet municipal discharge standards, and eliminating the need for chemical reagents during the treatment process, thus saving treatment costs.

[0005] Based on the above patent searches and understanding of existing textile wastewater filtration applications:

[0006] Traditional filtration devices mostly rely on static filtration, where wastewater flows slowly within the filter components and has a long filtration cycle, making it difficult to meet the large-volume wastewater treatment needs of the textile industry.

[0007] Textile wastewater contains a large amount of fiber debris, suspended solids and other impurities. These impurities easily adhere to the surface of the filter components, causing the filter holes to become clogged and affecting the filtration effect. Frequent shutdowns for cleaning are required. Although some devices are equipped with cleaning mechanisms, the cleaning range is limited and cannot fully cover the surface of the filter components. Moreover, the cleaning intensity is not adjustable, and it is not thorough in cleaning stubborn impurities. At the same time, the impurities after cleaning are not discharged smoothly, which can easily cause secondary pollution.

[0008] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a filtration device for textile wastewater treatment, in order to achieve a more practical purpose. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides a filtration device for textile wastewater treatment. This addresses the shortcomings of existing traditional filtration devices, which often rely on static filtration, resulting in slow wastewater flow within the filter components and long filtration cycles. These limitations make it difficult to meet the large-volume wastewater treatment needs of the textile industry. Furthermore, textile wastewater contains a large amount of fiber debris, suspended solids, and other impurities that easily adhere to the filter component surface, causing clogging of the filter pores, affecting filtration efficiency, and requiring frequent shutdowns for cleaning. While some devices have cleaning mechanisms, their cleaning range is limited, failing to fully cover the filter component surface, and the cleaning intensity is not adjustable, resulting in incomplete removal of stubborn impurities. Additionally, the discharge of cleaned impurities is often obstructed, easily causing secondary pollution.

[0011] Furthermore, a support leg frame is provided at the bottom of the treatment tank, a drain valve is provided on both sides of the bottom of the treatment tank, a controller is provided at the front end of the treatment tank, and an inlet pipe is provided at the middle of the rear end of the treatment tank, with the front end of the inlet pipe inserted into the rear end of the filter cartridge.

[0012] Furthermore, a feeding hopper is provided at the top rear of the processing tank, a Y-shaped inlet pipe is provided above the rear end of the inlet pipe, valves are provided at the three pipe positions of the Y-shaped inlet pipe, and an outlet pipe is fixedly installed below the rear end of the inlet pipe. The outlet pipe is equipped with a valve and is located directly below the Y-shaped inlet pipe.

[0013] Furthermore, a motor A is fixedly installed at the top front position of the adjustment frame, and the bottom shaft of the motor A is fixedly connected to the top position of the U-shaped frame. The U-shaped frame is rotatably connected to the inside front position of the adjustment frame.

[0014] Furthermore, the middle position of the U-shaped frame is rotatably connected to the front end position of the transmission component, the rear end position of the transmission component is rotatably connected to the front end position of the sliding component, and the transmission component is located in the middle and rear position inside the adjustment frame.

[0015] Furthermore, the transmission frame is fixedly connected to the front end of the motor C at its inner middle position, and the motor C's shaft is fixedly connected to the front middle position of the filter cartridge, with the filter cartridge located inside the three cleaning frames.

[0016] Furthermore, a motor B is fixedly installed at the top center of the transmission frame. The shaft of the motor B is fixedly connected to the top of the gear component. The gear component is located inside the transmission frame at the upper position, and the rear position of the gear component meshes with the front end of the gear ring component at the upper position.

[0017] Furthermore, the controller is connected to motor A, motor B, and motor C via a wiring harness.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The filter cylinder is driven to rotate by motor C, and centrifugal force is used to speed up the flow of wastewater through the filter cylinder, shorten the filtration cycle, and increase the wastewater treatment capacity per unit time. This meets the large-volume wastewater treatment needs of the textile industry. The reciprocating motion mechanism composed of the adjusting frame, sliding parts and transmission frame can drive the filter cylinder to move back and forth. The inertia effect promotes the rapid discharge of wastewater from the filter cylinder, further improving the filtration efficiency.

[0020] 2. The combination of rotation and reciprocating motion of the filter cartridge utilizes the inertia of water flow and its own motion to flush the inside of the filter cartridge, reducing the adhesion of impurities to the inner wall of the filter cartridge and reducing the risk of clogging from the source. The cleaning brush on the cleaning rack can thoroughly clean the outside of the filter cartridge, promptly removing attached impurities, preventing clogging of the filter holes, ensuring the continuity of the filtration process, and ensuring that the filter cartridge can be prevented from clogging on both the inside and outside.

[0021] 3. Motor B drives the gear ring to rotate through the gear components. The spiral groove of the gear ring meshes with the arc groove of the transmission arm, which can drive the three transmission arms to slide synchronously, thereby adjusting the distance between the cleaning brush and the filter cartridge. This ensures that the cleaning brush fits tightly against the surface of the filter cartridge, improving the cleaning power. The cleaning brush adopts a detachable design, which can be easily replaced when wear or damage occurs, ensuring a long-term stable cleaning effect. Attached Figure Description

[0038] Example:

[0039] As attached Figure 1 To be continued Figure 9 As shown:

[0040] This invention provides a filtration device for treating textile wastewater, comprising: a treatment tank 1; a mounting base 2 is fixedly installed at the front end of the treatment tank 1, the middle rear end of the mounting base 2 is fixedly connected to the middle front end of an adjusting frame 201, a sliding member 205 is slidably connected to the rear end of the adjusting frame 201, the middle rear end of the sliding member 205 is fixedly connected to the middle front end of a transmission frame 3, the transmission frame 3 is located at the middle front end of the treatment tank 1, and three sliding grooves are formed on the rear end face of the transmission frame 3. The transmission frame 3 is arranged in a ring. Each of the three grooves of the transmission frame 3 has a transmission arm 304 slidably connected. The front end face of each transmission arm 304 is provided with an arc-shaped groove. A cleaning frame 305 is fixedly installed on the outer rear end of each transmission arm 304. A detachable cleaning brush 306 is provided on the inner side of each cleaning frame 305. A toothed ring 301 is rotatably connected to the middle of the transmission frame 3. The rear end of the toothed ring 301 is provided with a spiral groove. The spiral groove of the toothed ring 301 meshes with the arc-shaped groove of the three transmission arms 304.

[0041] The bottom of the treatment tank 1 is provided with a support frame 101, and a drain valve 102 is provided on both sides of the bottom of the treatment tank 1. A controller 103 is provided at the front end of the treatment tank 1, and an inlet pipe 104 is provided at the middle of the rear end of the treatment tank 1. The front end of the inlet pipe 104 is inserted into the rear end of the filter cartridge 308.

[0042] The processing tank 1 has an addition hopper 105 at the top rear position, a Y-shaped inlet pipe 106 at the upper rear end of the inlet pipe 104, valves at all three pipe positions of the Y-shaped inlet pipe 106, and an outflow pipe 107 fixedly installed at the lower rear end of the inlet pipe 104. The outflow pipe 107 is equipped with a valve and is located directly below the Y-shaped inlet pipe 106.

[0043] Among them, a motor A202 is fixedly installed at the top front position of the adjustment frame 201, and the bottom shaft of the motor A202 is fixedly connected to the top position of the U-shaped frame 203. The U-shaped frame 203 is rotatably connected to the inside front position of the adjustment frame 201.

[0044] The middle position of the U-shaped frame 203 is rotatably connected to the front end position of the transmission component 204, the rear end position of the transmission component 204 is rotatably connected to the front end position of the sliding component 205, and the transmission component 204 is located in the middle and rear position inside the adjusting frame 201.

[0045] The transmission frame 3 is fixedly connected to the front end of the motor C307 at its inner middle position, and the motor C307's shaft is fixedly connected to the front middle position of the filter cartridge 308. The filter cartridge 308 is located inside the three cleaning frames 305.

[0046] Among them, a motor B302 is fixedly installed at the top middle position of the transmission frame 3. The rotating shaft of the motor B302 is fixedly connected to the top position of the gear component 303. The gear component 303 is located inside the transmission frame 3 at the upper position, and the rear position of the gear component 303 meshes with the front end of the gear ring component 301 at the upper position.

[0047] The controller 103 is connected to motor A202, motor B302, and motor C307 via a wiring harness.

[0048] When using:

[0049] When in use, first fix the processing tank 1 in a suitable position using the support bracket 101 to ensure the stability of the device. After connecting the power supply, start the operation of each component through the controller 103.

[0050] One pipe above the Y-shaped inlet pipe 106 is connected to the wastewater conveying pipe, and the other is connected to the cleaning liquid pipe. The valve of the corresponding pipe of the Y-shaped inlet pipe 106 is opened, and the textile wastewater enters the interior of the filter cartridge 308 through the Y-shaped inlet pipe 106 and the inlet pipe 104. The wastewater is filtered in the filter cartridge 308, and the filtered water is temporarily stored in the treatment tank 1. Impurities such as fiber debris are trapped on the surface of the filter cartridge 308 and will be discharged and transferred through the drain valves 102 on both sides of the bottom of the treatment tank 1.

[0051] The motor C307 is started by the controller 103. The shaft of the motor C307 drives the filter cartridge 308 to rotate. Through the action of centrifugal force, the wastewater entering the filter cartridge 308 is discharged into the treatment tank 1 at a faster speed, thereby improving the filtration efficiency. If it is necessary to add treatment flocculant, it can be added through the addition hopper 105 to improve the wastewater treatment effect.

[0052] When there are many impurities on the surface of the filter cartridge 308, the controller 103 starts the motor A202. The shaft of the motor A202 drives the U-shaped frame 203 to rotate inside the adjusting frame 201. The U-shaped frame 203 pushes the sliding member 205 to move back and forth along the rear position inside the adjusting frame 201 through the transmission member 204. The inertia drives the transmission frame 3 and its filter cartridge 308 to move back and forth. The filter cartridge 308 discharges the internal wastewater through inertia, further improving the filtration efficiency of the filter cartridge 308. It can also use the inertia of the back and forth movement and the inertia of the wastewater to flush the inside of the filter cartridge 308, preventing the filter cartridge 308 from becoming blocked.

[0053] When cleaning, close the valve connecting the wastewater supply pipe above the Y-shaped inlet pipe 106, and open another valve connecting the cleaning liquid pipe. The cleaning liquid will enter the filter cartridge 308. The rotating shaft of the motor A202 drives the U-shaped frame 203 to rotate inside the adjusting frame 201. The U-shaped frame 203 pushes the sliding member 205 to move back and forth along the rear position inside the adjusting frame 201 through the transmission member 204. This allows the inertia of the filter cartridge 308 to contact the cleaning liquid, cleaning the inside of the filter cartridge 308. After the inside of the filter cartridge 308 is cleaned, open the drain pipe 107 to drain larger debris from the inside of the filter cartridge 308. Combined with the rotation method of the filter cartridge 308, it can be ensured that all debris inside the filter cartridge 308 can be discharged to the drain pipe 107 through the inlet pipe 104 under the action of rotational inertia.

[0054] When debris is attached to the outer side of the filter cartridge 308, the motor B302 is started. The shaft of the motor B302 drives the gear 303 to rotate. The gear 303 meshes with the upper front end of the gear ring 301, causing the gear ring 301 to rotate within the transmission frame 3. Since the spiral groove of the gear ring 301 meshes with the arc groove of the transmission arm 304, the rotation of the gear ring 301 drives the three transmission arms 304 to slide inward synchronously along the sliding groove of the transmission frame 3, so that the cleaning frame 305 and the cleaning brush 306 further fit against the filter cartridge 308. During the continuous rotation of the filter cartridge 308, the cleaning brush 306 thoroughly cleans its surface. The debris that is cleaned falls to the bottom of the treatment tank 1. The debris generated during cleaning and the dirt that settles at the bottom of the treatment tank 1 can be discharged by opening the drain valves 102 on both sides of the bottom of the treatment tank 1.

[0055] When the cleaning brush 306 is worn or damaged, it can be directly disassembled and replaced with a new cleaning brush 306 to ensure the cleaning effect. The inside of the treatment tank 1 should be flushed and cleaned regularly through the drain valve 102 to keep the inside of the device clean.

[0056] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
