Description

Technical Field

[0001] This utility model relates to the field of tubular membrane equipment, specifically to a tubular membrane wastewater treatment and recycling device. Background Technology

[0002] Tubular membranes are an important product of the development of membrane separation technology. Originating in the mid-20th century, membrane separation technology has gradually become a highly efficient and energy-saving separation method with advancements in materials science and chemical processes. Compared to traditional separation technologies (such as distillation, centrifugation, and filtration), membrane separation offers advantages such as low energy consumption, no phase change, high selectivity, and ease of operation, thus finding widespread application in water treatment, food, pharmaceuticals, and chemical industries.

[0003] Currently, Chinese patent CN112340865A discloses a tubular microfiltration membrane wastewater treatment and recovery device, which includes a wastewater inlet pipe, an impurity filter, a filter screen sealing door, a water pump pipe, a high-pressure water pump, a filtration membrane system, a polymer structure filter screen, a drain outlet, a filtered water outlet, and an impurity filter screen. An impurity filter is installed in the wastewater inlet pipe for coarse screening of larger particles. The wastewater, after this initial screening, enters the filtration membrane system under the pressure of the high-pressure water pump. The filtration membrane system contains a polymer structure filter screen composed of a composite material membrane and a polytetrafluoroethylene (PTFE) membrane, which has excellent chemical stability. Furthermore, the entire filtration system is designed with an S-shaped structure to facilitate thorough and effective filtration of the wastewater throughout the system. Finally, the wastewater is discharged from the drain outlet at the bottom of the filtration system.

[0004] Although this tubular microfiltration membrane wastewater treatment and recycling device solves the problems of low wastewater treatment efficiency, long treatment time, and large footprint of microfiltration membrane systems, it often leaves too many impurities on the tubular membrane after wastewater treatment, requiring regular cleaning and maintenance, and those impurities need to be uniformly treated and recycled. Summary of the Invention

[0005] The purpose of this invention is to provide a tubular membrane wastewater treatment and recycling device, which has the advantages of effectively treating impurities on the surface of the tubular membrane and collecting and recycling them in a unified manner.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A tubular membrane wastewater treatment and recycling device includes a tubular membrane tank. A receiving device is provided below the tubular membrane tank. The receiving device includes a receiving box located below the tubular membrane tank and a stabilizing hole located in the middle of the receiving box. Support rods fixedly connected to the receiving box are provided around the stabilizing hole. A compression device is also provided at the bottom of the receiving box. The compression device includes a squeezing cylinder located on the outer wall below the receiving box. The outlet of the squeezing cylinder penetrates through the receiving box to the interior. A squeezing plate is also provided inside the receiving box where the outlet of the squeezing cylinder is located.

[0008] By adopting the above technical solution, the tubular membrane needs to be cleaned after long-term use. The tubular membrane can be directly removed from the tank. The tubular membrane filter tube can be fixed on the stable hole. Then, the surface impurities are rinsed and cleaned. The rinsed impurities are then squeezed and shaped. Excess water can be recycled and reused.

[0009] Further configuration: A recycling device is also provided below the receiving box. The recycling device includes a water collection pipe located at the bottom of the receiving box, an electrically controlled valve located on the water collection pipe, and a temporary storage box located at the outlet of the water collection pipe.

[0010] By adopting the above technical solution, the installed recycling device can effectively recycle the water after rinsing and cleaning.

[0011] Further features: The temporary storage box is also equipped with a drain outlet, the drain outlet is equipped with a drain valve, the temporary storage box is also equipped with a return water pipe connected to the tubular membrane tank, and the return water pipe is also equipped with a water pump.

[0012] By adopting the above technical solution, the provided temporary storage box can effectively store items temporarily, and then recycle them after the equipment is reassembled.

[0013] Further features: The temporary storage box is also equipped with a drain outlet, the drain outlet is equipped with a drain valve, the temporary storage box is also equipped with a return water pipe connected to the tubular membrane tank, and the return water pipe is also equipped with a water pump.

[0014] By adopting the above technical solution, the water collected in the temporary storage tank can be reintroduced into the tubular membrane system for recycling.

[0015] Further feature: A control valve is also provided on the return water pipe.

[0016] By adopting the above technical solution, the control valve can effectively control the switching.

[0017] Further features: The bottom of the receiving box is also provided with a discharge port, and the discharge port is also provided with an electric gate.

[0018] By adopting the above technical solution, the electric gate can be effectively opened when it is necessary to discharge the extruded solid waste, so that it falls to the outside for unified collection and treatment.

[0019] In summary, this utility model has the following beneficial effects: it can effectively and periodically clean the filter membrane inside the tubular membrane, compress the cleaned impurities into solid impurities, and recycle the water and other liquids in the cleaning process.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] The technical solution adopted in this utility model is:

[0025] A tubular membrane wastewater treatment and recovery device, such as Figure 1 As shown, the device includes a tubular membrane tank 1, with a receiving device 2 located below the tubular membrane tank 1. The receiving device 2 includes a receiving box 21 located below the tubular membrane tank 1, with a stabilizing hole 22 in the center of the receiving box 21. Support rods 23, which are fixedly connected to the receiving box 21, are located around the stabilizing hole 22. A compression device 3 is also provided at the bottom of the receiving box 21. The compression device 3 includes a compression cylinder 31 located on the outer wall below the receiving box 21. The outlet of the compression cylinder 31 penetrates through the receiving box 21 into the interior. An compression plate 32 is also provided inside the receiving box 21 where the outlet of the compression cylinder 31 is located. Below the receiving box 21, there is a recycling device 4. The recycling device 4 includes a water collection pipe 41 located at the bottom of the receiving box 21. The water collection pipe 41 is equipped with an electric control valve 42. The outlet of the water collection pipe 41 is equipped with a temporary storage box 43. The temporary storage box 43 is also equipped with a drain outlet 5. The drain outlet 5 is equipped with a drain valve 6. The temporary storage box 43 is also equipped with a return water pipe 7 connected to the tubular membrane tank 1. The return water pipe 7 is also equipped with a water pump 8 and a control valve 9. At the bottom of the receiving box 21, there is also a discharge port 10. The discharge port 10 is also equipped with an electric gate 11.

[0026] Its main working principle is as follows: The receiving box 21 provided under the tubular membrane tank 1 can effectively remove the membrane column from the tubular membrane and place it in the stabilizing hole 22. At the same time, the membrane column is cleaned and washed, and the impurities remaining on the surface of the membrane column are brushed down into the receiving box 21 below. The water collection pipe 41 provided in the receiving box 21 can effectively drain excess water. At the same time, the squeezing cylinder 31 is activated, and the squeezing plate 32 is pushed to squeeze the solid impurities remaining in the receiving box 21. After the excess water is squeezed out, a solid block is formed. Then, the entire solid impurity can be discharged by opening the electric gate 11, so as to carry out unified treatment and recycling. The excess water will enter the temporary storage box 43 through the water collection pipe 41, and then return to the cleaned tubular membrane for recycling.
