Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a high-efficiency treatment device for dyeing and printing wastewater. Background Technology

[0002] As a crucial link in the textile industry chain, the dyeing and printing industry generates a large amount of dyeing and printing wastewater during its production process. This wastewater is characterized by high color intensity, high organic content, complex and variable composition, and poor biodegradability. If it is discharged directly into the environment without proper treatment, it will cause long-term and irreversible serious pollution to ecosystem elements such as water bodies and soil, thereby endangering human health and ecological balance.

[0003] In traditional dyeing and printing wastewater treatment systems, the wastewater pumping pipes play a crucial role in transporting the wastewater. However, the bends in these pipes become a weak point in the entire system. Due to the large amounts of dye particles, fiber impurities, unreacted chemicals, and precipitates generated during treatment carried by the dyeing and printing wastewater, these substances easily deposit and adhere at the bends due to changes in flow direction and local turbulence. Over time, the accumulation of dirt and blockages significantly reduces the effective inner diameter of the pipes, leading to a substantial increase in wastewater transport resistance, a decrease in flow velocity, and a sharp decline in the overall treatment efficiency. Furthermore, the presence of blockages can alter the flow pattern, causing uneven residence time distribution within the treatment system. This affects the treatment effectiveness of various units (such as biological reaction tanks and flocculation sedimentation units), reduces pollutant removal rates, and fails to meet increasingly stringent environmental emission standards.

[0004] Furthermore, the fixed connection method of water pipe bends in traditional treatment devices makes cleaning these dirt and blockages extremely difficult. It often requires stopping the entire treatment unit and expending significant manpower and time to disassemble surrounding components before cleaning the bends. This complex and inefficient maintenance method not only increases the company's operating costs but also disrupts the continuity of dyeing and printing production due to prolonged equipment downtime, resulting in substantial economic losses for the company.

[0005] In view of this, in order to overcome the cleaning difficulties of the sewage pipe bends in traditional dyeing and printing wastewater treatment devices and improve the maintenance convenience and overall operating efficiency of the treatment devices, a high-efficiency dyeing and printing wastewater treatment device with detachable bends is proposed. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies by allowing the second pipe section to be easily separated from the first pipe section through simple rotation of the external fastener. This facilitates direct cleaning of the bent parts, significantly reducing cleaning time and labor costs, and effectively solving the problem of low processing efficiency caused by pipe blockage.

[0007] In order to solve the above-mentioned technical problems, the present invention solves the cleaning problem at the bend of the sewage pipe in the dyeing and printing wastewater treatment device through the following technical solution.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A high-efficiency treatment device for dyeing and printing wastewater includes a treatment device body and a drainage structure disposed thereon. A wastewater tank is provided on one side of the treatment device body. The drainage structure consists of a first pipe section and a second pipe section. One end of the drainage structure is connected to the treatment device body, and the other end extends into the wastewater tank. A first connecting pipe head is connected to the outlet end of the first pipe section, and a second connecting pipe head is connected to the inlet end of the second pipe section. The first connecting pipe head and the second connecting pipe head are matched with each other, and the second connecting pipe head is sleeved on the outside of the first connecting pipe head. The outer surfaces of the first connecting pipe head and the second connecting pipe head are provided with threads, and are connected by rotating external fasteners that engage with the threads.

[0010] Preferably, the inner and outer ends of the first connecting pipe head and the second connecting pipe head are in a mating state, and a sealing ring is provided at the joint between the inner ends of the second connecting pipe head and the first connecting pipe head for sealing.

[0011] Preferably, a concave annular ring is provided on the inner wall of the second connecting pipe head, and an outer positioning hoop is glued to the outer periphery of the sealing ring, with the other end of the outer positioning hoop inserted into the concave annular ring along the opening.

[0012] Preferably, a first limiting ring is connected to the outer wall of the first connecting pipe head, and a fourth limiting ring is connected to the lower end of the outer wall of the outer fastener. The fourth limiting ring and the first limiting ring cooperate with each other to restrict the downward movement of the outer fastener.

[0013] Preferably, a stabilizing pad is glued to the bottom of the connection between the outer fastener and the fourth limiting ring, and the fourth limiting ring can make contact with the surface of the first limiting ring for stability.

[0014] Preferably, a third limiting ring is connected to the upper end of the outer wall of the outer fastener, and a second limiting ring is connected to the upper end of the outer wall of the second section tube. The third limiting ring and the second limiting ring cooperate with each other to restrict the upward movement of the outer fastener.

[0015] Preferably, the third limiting ring has a plurality of circular grooves evenly distributed on it.

[0016] Preferably, an internal pad is glued to the inner wall of the circular groove to prevent slippage.

[0017] Preferably, the built-in pad is made of rubber.

[0018] Preferably, the outer periphery of the outer positioning hoop is constructed to have an elastic curvature that adapts to the inner wall of the concave annular ring.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The high-efficiency treatment device for dyeing and printing wastewater provided in this application allows for easy separation of the second pipe section from the first pipe section by simply rotating the external fasteners. This facilitates direct cleaning of the bent parts, greatly reducing cleaning time and labor costs, and effectively solving the problem of low treatment efficiency caused by pipe blockage.

[0021] This application improves the efficiency of the cleaning process, reduces equipment downtime caused by complex maintenance procedures, and enables more continuous and stable dyeing and printing production. Simultaneously, it reduces reliance on specialized maintenance personnel and tools, further saving maintenance costs. It avoids the problems of increased wastewater transport resistance and reduced flow velocity caused by blockages in pipe bends. The stable water flow ensures that each treatment unit within the treatment device operates normally according to design parameters, allowing dyeing and printing wastewater to be fully treated at each stage, thereby maintaining high treatment efficiency, effectively reducing wastewater pollutant content, and improving the effluent quality compliance rate.

[0022] The detachable connection method of this application allows for the rapid replacement of damaged or upgraded pipe components, improving the reliability and service life of the entire treatment device. Furthermore, this flexible connection structure facilitates adjustments and optimization of the piping system to meet the specific needs of different dyeing and printing wastewater treatment processes, enhancing the adaptability of the treatment device to various dyeing and printing wastewater treatment scenarios.

[0023] The sealing ring and the matching design of the outer positioning clamp and the inner concave annular ring at the joint of the first and second connecting pipe ends in this application ensure a good sealing effect at the connection. This effectively prevents the leakage of dyeing and printing wastewater at the pipe connection, avoiding environmental pollution and water waste caused by leakage. At the same time, it also ensures the stability of the internal pressure of the treatment device, which is conducive to the normal operation of each treatment process.

[0024] This application utilizes the precise positioning of external fasteners through the first, second, third, and fourth limiting rings, along with the enhanced friction provided by the stabilizing gasket, to ensure high stability of the pipeline connection structure during operation. It can withstand the impact of water flow, pressure fluctuations, and vibrations during the transportation of dyeing and printing wastewater, reducing the risk of malfunctions caused by loose pipeline connections and guaranteeing the long-term stable operation of the treatment device.

Example

[0037] Please see Figure 1-6 A high-efficiency treatment device for dyeing and printing wastewater includes a treatment device body 1 and a drainage structure installed thereon. A sewage tank 2 is provided on one side of the treatment device body 1. The drainage structure consists of a first pipe section 3 and a second pipe section 4. One end of the drainage structure is connected to the treatment device body 1, and the other end extends into the sewage tank 2. The outlet end of the first pipe section 3 is connected to a first connecting pipe head 301, and the inlet end of the second pipe section 4 is connected to a second connecting pipe head 401. The first connecting pipe head 301 and the second connecting pipe head 401 are matched with each other, and the second connecting pipe head 401 is sleeved on the outside of the first connecting pipe head 301. The outer surfaces of the first connecting pipe head 301 and the second connecting pipe head 401 are both provided with threads, and are connected to the threads by rotating external fasteners 5.

[0038] The efficient treatment device for dyeing and printing wastewater of this application is mainly composed of the treatment device body 1, sewage tank 2, first pipe section 3, first connecting pipe head 301, second pipe section 4, second connecting pipe head 401 and external fasteners 5. The following is a detailed description of the structure and working principle.

[0039] I. Device Assembly

[0040] First, prepare the first connecting pipe head 301 to connect the outlet end of the first section of pipe 3 and the second connecting pipe head 401 to connect the inlet end of the second section of pipe 4. Ensure that the surfaces of the first connecting pipe head 301 and the second connecting pipe head 401 are clean and free of impurities. Check that the threads on the outer surfaces of the first connecting pipe head 301 and the second connecting pipe head 401 are intact and undamaged. Fit the second connecting pipe head 401 onto the outside of the first connecting pipe head 301, making them fit together. During this process, ensure that both the inner and outer ends of the first connecting pipe head 301 and the second connecting pipe head 401 are tightly mated.

[0041] A sealing ring 6 is installed at the joint where the second connecting pipe head 401 and the first connecting pipe head 301 meet internally. The sealing ring 6 is made of rubber and has good sealing performance.

[0042] For the installation of the sealing ring 6, first, glue the outer positioning clamp 601 to the outer circumference of the sealing ring 6, and then insert the other end of the outer positioning clamp 601 into the concave annular ring 602 opening on the inner wall of the second connecting pipe head 401. The outer circumference of the outer positioning clamp 601 is constructed with an elastic arc that adapts to the inner wall of the concave annular ring 602, which facilitates smooth insertion and fixation of the sealing ring 6.

[0043] External fastener 5 installation and limiting

[0044] Take the outer fastener 5 and connect it to the threads on the outer surfaces of the first connecting pipe head 301 and the second connecting pipe head 401 via thread engagement. Since the length of the thread on the second connecting pipe head 401 is much greater than that on the first connecting pipe head 301, the outer fastener 5 can move on it.

[0045] Inspect the first limiting ring 302 connected to the outer wall of the first connecting pipe head 301 and the fourth limiting ring 502 connected to the lower end of the outer wall of the outer fastener 5. When rotating the outer fastener 5 until it moves onto the thread of the first connecting pipe head 301, ensure that the fourth limiting ring 502 cooperates with the first limiting ring 302 to limit the downward movement of the outer fastener 5.

[0046] At the contact point between the fourth limiting ring 502 and the first limiting ring 302, a stabilizing pad 503, glued to the bottom of their connection, increases friction, making the connection more stable. The stabilizing pad 503 is made of rubber.

[0047] Meanwhile, note the third limiting ring 501 connected to the upper end of the outer wall of the outer fastener 5 and the second limiting ring 4011 connected to the upper end of the outer wall of the second section of pipe 4. When disassembly is required, rotate the outer fastener 5 to disengage from the threaded section of the first connecting pipe head 301 and return it to the threaded section of the second connecting pipe head 401, and make the third limiting ring 501 and the second limiting ring 4011 cooperate with each other to restrict the upward movement of the outer fastener 5. At this time, the locking state between the first connecting pipe head 301 and the second connecting pipe head 401 can be released, and the second section of pipe 4 can be separated from the first section of pipe 3.

[0048] Several circular grooves 5011 are evenly provided on the third limiting ring 501. An inner pad 5012 is glued to the inner wall of the circular groove 5011. The inner pad 5012 is made of rubber, which makes it convenient to hold the circular groove 5011 to rotate the third limiting ring 501 and prevent the hand from slipping.

[0049] Device operation

[0050] The dyeing and printing wastewater enters the treatment device body 1 from the wastewater tank 2 through the drainage structure. The drainage structure consists of a first pipe section 3 and a second pipe section 4. The first pipe section 3 draws the wastewater out of the wastewater tank 2, and the second pipe section 4, which is bent, transports the wastewater to the treatment device body 1.

[0051] The treatment unit 1 treats the incoming dyeing and printing wastewater. The treatment process can include various physical, chemical and biological treatment methods, such as flocculation, sedimentation and biochemical reactions, to reduce pollutant indicators such as color and organic matter content in the wastewater.

[0052] The treated water is discharged from the other side of the treatment unit 1, meeting the requirements of environmental protection emission standards.

[0053] II. Working Principle

[0054] Pipe connection and sealing principles

[0055] Connection principle

[0056] The sleeved and threaded fastening method between the first connecting pipe end 301 and the second connecting pipe end 401 is a design that combines mechanical connection and sealing. The sleeved part provides a certain degree of connection stability and initial sealing effect, while the threaded fastening further enhances the reliability and sealing performance of the connection. The movement of the external fastener 5 on the thread, through its cooperation with various limit rings, realizes the conversion between the connected and disassembled states. This design not only ensures the robustness of the pipeline connection during normal operation, enabling it to withstand the pressure and vibration during wastewater transportation, but also allows for convenient and quick operation when disassembly is required.

[0057] The design of the limiting rings is based on mechanical principles. By restricting the movement of the outer fastener 5 in different directions, the stability and reliability of the connection are ensured. For example, the cooperation between the first limiting ring 302 and the fourth limiting ring 502 utilizes the principles of friction and mechanical obstruction. When the outer fastener 5 moves down to a certain position, the fourth limiting ring 502 contacts the first limiting ring 302. Due to the action of friction and the mechanical structural restriction between them, the outer fastener 5 cannot continue to move down, thus ensuring the tightness of the connection.

[0058] Sealing principle

[0059] The sealing effect of the sealing ring 6 is based on the principle of elastic deformation of materials. When the pipes are connected and tightened, the sealing ring 6 undergoes elastic deformation under the mating pressure of the first connecting pipe head 301 and the second connecting pipe head 401, filling the tiny gap at the joint and thus preventing leakage of dyeing wastewater. The engagement of the outer positioning clamp 601 and the inner concave annular ring 602 is to fix the position of the sealing ring 6, preventing it from shifting or falling off under pressure. This sealing structure design is simple and effective, adaptable to a certain range of pipe connection tolerances and pressure variations, ensuring the sealing performance of the pipeline system.

[0060] Disassembly operation principle

[0061] The disassembly operation is based on the reversible engagement between the external fastener 5 and the threaded connection of the connecting pipe head. By rotating the external fastener 5, its position on the thread is changed, thereby releasing the tightening force on the first connecting pipe head 301 and the second connecting pipe head 401. When the external fastener 5 moves from the threaded section of the first connecting pipe head 301 to the threaded section of the second connecting pipe head 401 and engages with the second limiting ring 4011 to restrict upward movement, the connection force between the first connecting pipe head 301 and the second connecting pipe head 401 is released, at which point the second pipe section 4 can be easily separated from the first pipe section 3. This detachable design overcomes the difficulties faced by traditional fixed connection methods when cleaning pipe bends, greatly improving the ease and flexibility of device maintenance. After the pipe is cleaned, the pipe can be reconnected and tightened by reversing the operation steps, restoring the device to normal operation.

[0062] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
