Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a membrane treatment device for industrial wastewater treatment. Background Technology

[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production processes. It contains industrial raw materials, intermediate products, and finished products lost with the water, as well as pollutants generated during the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety.

[0003] Membrane treatment technology is an effective means of water purification and purification. It can remove suspended solids, bacteria, toxic metals, organic matter, and even dissolved salts from water. Membrane technologies include microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. They can be combined with traditional physicochemical and biological treatment technologies to form the best combination for industrial wastewater treatment.

[0004] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN217498805U, which discloses a membrane treatment device for industrial wastewater treatment, including a wastewater treatment tank and a drain pipe set on the top right side of the wastewater treatment tank. An installation frame is movably installed inside the wastewater treatment tank, and a membrane module is fixedly installed at the bottom of the installation frame. Lifting seats are slidably installed on the inner walls of both sides of the wastewater treatment tank. A transverse sleeve is fixedly connected to the side of the two lifting seats that are close to each other. A movable connecting rod is movably sleeved on the inner end of the transverse sleeve, and the two ends of the installation frame are respectively fixedly connected to one end of the movable connecting rod.

[0005] This membrane treatment device for industrial wastewater treatment allows for adjustment of the membrane module's position during use. However, when disassembling and replacing the membrane module, the motor and threaded pipe can only lift the mounting frame to a position flush with the top of the treatment tank. Then, the mounting frame must be positioned first, followed by disassembling all components such as the sprocket, shaft, and rack between the mounting frame and the lifting seat. Finally, the mounting frame is moved out using hoisting equipment before the membrane module can be replaced. This reduces the convenience of membrane module replacement and consequently lowers the efficiency of industrial wastewater membrane treatment. Utility Model Content

[0006] In order to improve the efficiency of membrane treatment for industrial wastewater, this utility model provides a membrane treatment device for industrial wastewater treatment.

[0007] This application provides a membrane treatment device for industrial wastewater treatment, which adopts the following technical solution:

[0008] A membrane treatment device for industrial wastewater treatment includes a temperature control tank, a neutralization tank, and a treatment tank arranged sequentially. The temperature control tank is equipped with a temperature control device for adjusting the wastewater temperature. The neutralization tank is connected to the temperature control tank and is equipped with a control component for adjusting the pH of the wastewater. The treatment tank is connected to the neutralization tank and is equipped with a membrane module for treating the wastewater. The treatment tank is equipped with an adjustment mechanism for adjusting the position of the membrane module.

[0009] By adopting the above technical solution, the wastewater is temperature-regulated in a temperature-regulating tank, and then pH-regulated in a neutralization tank. The regulating mechanism moves the position of the membrane module. The regulated wastewater enters the treatment tank and is purified by the membrane module. By regulating the wastewater quality and state through temperature and pH, the efficiency of the membrane module is improved, thereby improving the efficiency of industrial wastewater membrane treatment.

[0010] Optionally, the adjustment mechanism includes:

[0011] The mounting frame is movably disposed within the treatment tank. The membrane module is detachably mounted on the mounting frame via a connecting assembly. Traction rings are provided on both opposite side walls at the top of the mounting frame.

[0012] Two winches are provided, each corresponding to a traction ring. The two winches are positioned opposite each other on the treatment pool. The distance between the winches and the upper surface of the treatment pool is greater than the height of the mounting frame. A traction rope is wound on the winch. The end of the traction rope away from the winch has a traction hook. The traction hook is detachably attached to the traction ring.

[0013] A mobile component, which is located on the processing pool and connected to the winch and used to drive the winch to move.

[0014] By adopting the above technical solution, the moving component starts and drives the winch to move outside the treatment tank. The mounting frame with the membrane module installed is hooked onto the winch. The winch starts and drives the mounting frame to rise above the treatment tank. Then, the moving component drives the winch to move directly above the treatment tank. The winch starts and lowers the mounting frame into the treatment tank. When replacement is needed, the operation is reversed. This realizes the installation and removal of the mounting frame, thereby improving the convenience of membrane module replacement and position adjustment, and thus improving the efficiency of industrial wastewater membrane treatment.

[0015] Optionally, the moving component includes:

[0016] A mounting frame is provided above the treatment tank;

[0017] A movable plate is slidably mounted on a fixed frame and located above the treatment pool. The top of the fixed frame is provided with sliding grooves on the two inner side walls opposite each other for the movable plate to slide. Both winches are mounted on the movable plate.

[0018] A driving component, which is mounted on a fixed frame and is used to drive the moving plate to move within the sliding groove.

[0019] By adopting the above technical solution, the membrane module is installed on the mounting frame outside the treatment tank. The drive unit drives the moving plate to slide along the sliding groove to the outside of the treatment tank. The winch lowers the traction rope so that the traction hook is hooked on the traction ring. Then the winch starts to wind up the traction rope, thereby moving the mounting frame upward. Then the drive unit starts to move the moving plate back to directly above the treatment tank. The winch lowers the traction rope to move the mounting frame down into the treatment tank. When it needs to be moved out for replacement, the operation is reversed. This improves the convenience of membrane module replacement and position adjustment.

[0020] Optionally, the driving element includes:

[0021] The first screw is rotatably disposed in one of the sliding grooves and is threadedly engaged with one end of the moving plate;

[0022] A guide rod is provided in a sliding groove away from the first screw and passes through the end of the moving plate away from the first screw;

[0023] A drive motor is mounted on a fixed frame and its output end is connected to the first screw drive.

[0024] By adopting the above technical solution, the drive motor starts and drives the first screw to rotate, the guide rod limits the movement direction of the moving plate, and the rotation of the first screw drives the moving plate to slide along the length of the sliding groove, thereby realizing the adjustment of the horizontal position of the winch, which improves the convenience of installing and removing the mounting frame.

[0025] Optionally, the movable plate has two movable slots along its length that correspond one-to-one with the winch, and the movable plate is provided with a sliding component for driving the winch to slide within the movable slots.

[0026] By adopting the above technical solution, the sliding component drives the winch to move within the moving slot, thereby realizing the adjustment of the mounting frame's placement position.

[0027] Optionally, the sliding component includes:

[0028] A sliding block, which is fixed to the lower surface of the winch and slidably disposed in the moving groove;

[0029] The second screw is rotatably disposed in the moving groove and threadedly engaged with the sliding block;

[0030] A sliding motor is mounted on a movable plate and its output end is connected to a second screw drive.

[0031] By adopting the above technical solution, the sliding motor starts and drives the second screw to rotate. The second screw drives the winch to move in the moving slot through the sliding block. The installation position of the mounting frame can be adjusted by adjusting the position of the two winches, thereby improving the convenience of adjusting the installation position of the membrane module.

[0032] Optionally, the connection component includes:

[0033] A connecting plate, which is fixedly installed in the mounting frame, has multiple water passage holes;

[0034] A connecting ring, which is fixed to the outer surface of the bottom end of the membrane module and abuts against the connecting plate;

[0035] A connecting bolt, which passes through the connecting ring and is threadedly connected to the connecting plate.

[0036] By adopting the above technical solution, during installation, the connecting ring is pressed against the connecting plate, and the connecting bolts are tightened to position the connecting ring. During the treatment process, wastewater can flow through the water passage, thereby reducing the obstruction of the water flow by the connecting plate. Disassembly can be performed by reversing the operation, which improves the convenience of membrane module installation, positioning, disassembly and replacement, thereby improving the efficiency of industrial wastewater membrane treatment.

[0037] Optionally, an aeration fan is provided outside the treatment tank, and an aeration pipe is provided inside the treatment tank. The aeration pipe is located below the connecting plate and connected to the aeration fan.

[0038] By adopting the above technical solution, aeration is carried out in the treatment tank through aeration blowers and aeration pipes, thereby increasing the turbulence velocity of wastewater and thus increasing the efficiency of industrial wastewater membrane treatment.

[0039] Optionally, the temperature control device includes an inlet pipe and a wastewater pipe. The inlet pipe is connected to the temperature control tank and is used to introduce a liquid with a temperature. The wastewater pipe is spiral-shaped and located inside the temperature control tank. The inlet end of the wastewater pipe is used to introduce wastewater, and the outlet end of the wastewater pipe is connected to a neutralization tank.

[0040] By adopting the above technical solution, it is found that when the temperature of industrial wastewater is too high or too low, it will damage the membrane module. Therefore, the temperature of the wastewater is first adjusted by introducing a liquid with a certain temperature. When the wastewater flows in the wastewater pipe, it exchanges heat with the liquid through the pipe wall, thereby achieving the adjustment of the wastewater temperature. The spiral design increases the contact time between the wastewater pipe and the liquid, improves the heat exchange efficiency, and thus achieves the adjustment of the wastewater temperature.

[0041] Optionally, the control component includes an acid pickling tank and an alkaline pickling tank. The acid pickling tank is located on top of the neutralization tank and is connected to the neutralization tank via an acid pipe. The alkaline pickling tank is located on top of the neutralization tank and is connected to the neutralization tank via an alkaline pipe.

[0042] By adopting the above technical solution, the wastewater enters the neutralization tank after temperature adjustment. Different washing solutions are added according to the composition of the wastewater to remove some simple and small molecule impurities in the industrial wastewater. Furthermore, the wastewater quality is adjusted by adjusting the pH, thereby improving the efficiency of industrial wastewater membrane treatment.

[0043] In summary, this application includes at least one of the following beneficial technical effects:

[0044] 1. Wastewater undergoes temperature regulation in a temperature control tank, followed by pH adjustment in a neutralization tank. The adjustment mechanism moves the membrane module, and the regulated wastewater enters the treatment tank for purification through the membrane module. By adjusting the temperature and pH of the wastewater, the quality and state of the wastewater are improved, thereby increasing the efficiency of the membrane module and thus enhancing the efficiency of industrial wastewater membrane treatment.

[0045] 2. The membrane module is installed on the mounting frame outside the treatment tank. The mounting frame can be placed and moved out through the cooperation of the drive unit, winch, moving plate and sliding component, thereby improving the convenience of membrane module replacement and position adjustment.

[0046] 3. The membrane module and the mounting frame are detachably connected, which improves the convenience of membrane module disassembly, maintenance and replacement, thereby improving the efficiency of membrane treatment of industrial wastewater. Attached Figure Description

Furthermore, the membrane module 31 and the mounting frame 41 are detachably connected, which improves the convenience of membrane module 31 disassembly, maintenance and replacement, thereby improving the efficiency of industrial wastewater membrane treatment.

[0074] Reference Figure 1 , Figure 2 and Figure 3 Wastewater flows in wastewater pipe 13. When passing through temperature control tank 1, it exchanges heat with the liquid through the pipe wall of wastewater pipe 13. The spiral design increases the contact time between wastewater pipe 13 and liquid, improving heat exchange efficiency. After temperature adjustment, the wastewater enters neutralization tank 2. Different washing solutions are added according to the composition of the wastewater to remove some simple and small molecule impurities in the industrial wastewater. Furthermore, the wastewater quality is adjusted by pH adjustment, which not only reduces damage to membrane module 31 but also improves the efficiency of industrial wastewater membrane treatment.
