Description

Technical Field

[0001] This utility model belongs to the field of ceramic membrane filtration equipment for organic dyes, specifically a ceramic membrane high-efficiency filtration component for organic dyes. Background Technology

[0002] Ceramic membrane filters are a type of high-efficiency precision filtration equipment widely used in chemical, pharmaceutical, water treatment, and food industries. Their core component is an inorganic ceramic membrane, which has advantages such as thermal stability, chemical corrosion resistance, and high strength. In the field of organic dyes, ceramic membrane filters are mainly used to remove dye molecules from wastewater, achieving decolorization and COD reduction. Through membrane separation technology, dye molecules in wastewater are concentrated and recovered, realizing resource reuse. Organic dye wastewater typically contains particulate matter, which mainly originates from reaction residues and precipitates during the production process. When these particles enter the pores of ceramic membranes, they can easily cause membrane pore blockage or accumulate on the membrane surface, forming a filter cake layer. This increases filtration resistance, raises the transmembrane pressure differential, and ultimately reduces separation efficiency. Currently, the common practice is to backwash the ceramic membrane filter periodically to reduce the membrane pressure differential. Although cleaning can restore the membrane's performance, some particles will still remain in the membrane pores. Over time, these particles will cause membrane pore blockage, thus affecting the service life of the ceramic membrane.

[0003] In summary, this utility model provides a ceramic membrane organic dye high-efficiency filtration component to solve the above problems. Utility Model Content

Detailed Implementation

[0014] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0015] Example 1 like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a ceramic membrane organic dye high-efficiency filtration component, including a filter component 100 for filtering organic dye wastewater, and a separation component 200, including a separation tank 210 for wastewater pretreatment, a screen 220 installed in the inner cavity of the separation tank 210 for intercepting particulate matter, a storage tank 230 for storing pretreated wastewater, a cleaning component 240 for cleaning the separation tank 210, and a support leg 250 for supporting the separation tank 210. The separation tank 210 includes a cylinder 211 for providing separation space, a top cover 212 located at the top of the cylinder 211 for sealing the cylinder 211, a conical hopper 213 located at the bottom of the cylinder 211 for collecting particulate matter, a connecting pipe 214 communicating with the storage tank 230, a drain pipe 216 for discharging particulate matter and flushing water, and an inlet pipe 218 for introducing organic dye wastewater.

[0016] like Figure 1-4As shown, the separation tank 210 and screen 220 in the separation assembly 200 serve as pretreatment for organic dye wastewater. The screen 220, installed inside the separation tank 210, intercepts particulate matter in the wastewater. Before the wastewater enters the ceramic membrane 140 for filtration, most of the larger particles are intercepted by the screen 220, preventing them from directly entering the ceramic membrane 140 and thus reducing the possibility of particle residue and blockage in the membrane pores. The conical hopper 213, located at the bottom of the cylinder 211, is used to collect particulate matter, and the inlet pipe 218 is located on the surface of the conical hopper 213. At the top, the drain pipe 216 is located at the bottom of the conical hopper 213, which makes it easier for particulate matter to settle to the bottom of the conical hopper 213 under the action of gravity. Then, by opening the drain valve 217, the particulate matter and flushing water can be conveniently discharged from the separator 210, reducing the residue of particulate matter in the system. The cleaning component 240 can clean the separator 210, and can promptly flush down the particulate matter intercepted on the screen 220 and in the separator 210, and discharge it through the drain pipe 216, further preventing particulate matter from entering the ceramic membrane 140 with the wastewater and reducing the risk of membrane pore blockage.

[0017] Example 2 Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0018] In this embodiment, the filter assembly 100 includes a base 110, an inlet pump 120 fixed to the top of the base 110 for conveying wastewater, a circulation pump 130 for internal circulation, a ceramic membrane 140 for wastewater filtration, a circulation delivery pipe 150 for communicating between the circulation pump 130 and the ceramic membrane 140, a membrane support 160 for supporting the ceramic membrane 140, and both the membrane support 160 and the storage tank 230 are fixed to the top of the base 110.

[0019] The top cover 212 is fixed to the top of the cylinder 211 by a clamp, and the conical hopper 213 is fixed to the bottom of the cylinder 211 by a clamp. Both the top cover 212 and the conical hopper 213 are connected to the inner cavity of the cylinder 211, and the screen 220 is fixed to the inner cavity of the cylinder 211.

[0020] The liquid inlet pipe 218 is located at the upper end of the surface of the conical hopper 213 and communicates with the inner cavity of the conical hopper 213. The sewage outlet pipe 216 is located at the bottom of the conical hopper 213 and communicates with the inner cavity of the conical hopper 213. Support legs 250 are fixedly connected to all four sides of the surface of the conical hopper 213.

[0021] One end of the connecting pipe 214 is connected to the inner cavity of the top cover 212, and the other end of the connecting pipe 214 is connected to the inner cavity of the liquid storage tank 230. A connecting valve 215 is connected to the surface of the connecting pipe 214, and a drain valve 217 is connected to the surface of the drain pipe 216.

[0022] The cleaning assembly 240 includes a flushing water pump 241, a water distribution box 242 located at the upper end of the inner cavity of the top cover 212, a nozzle 243 connected to the bottom of the water distribution box 242, and a flushing pipe 244 for communicating between the flushing water pump 241 and the water distribution box 242.

[0023] The inlet of the flushing water pump 241 is connected to the external clean water tank through a pipe. One end of the flushing pipe 244 is connected to the outlet of the flushing water pump 241, and the other end of the flushing pipe 244 passes through the inner cavity of the top cover 212 and is connected to the inner cavity of the water distribution box 242. A regulating valve 245 is connected to the surface of the flushing pipe 244.

[0024] like Figure 1-4 As shown, the inlet pump 120 transports the pretreated wastewater from the storage tank 230 to the ceramic membrane 140 for filtration. The circulation pump 130 circulates the wastewater within the ceramic membrane 140 through the circulation delivery pipe 150, further improving the filtration effect. The filter assembly 100 is a ceramic membrane filter disclosed in the prior art. For specific pipe connections and operation methods, please refer to the ceramic membrane filtration device with patent number 202121976449.3 in the prior art. The circulation delivery pipe 150 is used to connect the circulation pump 130 and the ceramic membrane 140. The cleaning assembly 240 includes a flushing water pump 241, a water distribution box 242, a nozzle 243, and a flushing pipe 244. The flushing water pump 241 delivers clean water from the external clean water tank to the water distribution box 242, and then the nozzle 243 flushes the inside of the separation tank 210. This can promptly flush down particles intercepted on the screen 220 and inside the separation tank 210, and discharge them through the drain pipe 216. This further prevents particles from entering the ceramic membrane 140 with the wastewater. Through the pretreatment and cleaning of the separation assembly 200, the number of particles entering the ceramic membrane 140 in the filter assembly 100 is reduced. The ceramic membrane 140 in the filter assembly 100 only needs to treat the pre-purified wastewater, reducing its workload and the probability of membrane pore blockage, thereby helping to extend the service life of the ceramic membrane.

[0025] In use, organic dye wastewater enters the conical hopper 213 of the separator 210 through the inlet pipe 218. The inlet pipe 218 is located at the upper end of the surface of the conical hopper 213, ensuring that the wastewater enters the separator 210 smoothly. The wastewater rises from the conical hopper 213 into the cylinder 211. The screen 220 in the inner cavity of the cylinder 211 intercepts the particles. The screen 220 is fixed in the inner cavity of the cylinder 211, which can effectively prevent large particles of impurities from continuing to flow with the wastewater. The wastewater filtered by the screen 220 flows into the storage tank 230 through the connecting pipe 214. The connecting valve 215 on the surface of the connecting pipe 214 can control the flow of wastewater. The intercepted particles will fall into the bottom of the conical hopper 213 under the action of gravity. By opening the drain valve 217 on the surface of the drain pipe 216, the particles and rinsing water can be discharged together. During maintenance of the separator 210, the inlet of the flushing water pump 241 is connected to an external clean water tank through a pipe to draw in clean water. The clean water is then transported to the water distribution box 242 through the flushing pipe 244. The regulating valve 245 on the surface of the flushing pipe 244 can adjust the water flow. The water distribution box 242 is located at the upper end of the inner cavity of the top cover 212, which can evenly distribute the clean water. The nozzle 243 at the bottom of the water distribution box 242 sprays clean water to flush the cylinder 211 and the screen 220, making it easier for the attached particles to fall into the bottom of the conical hopper 213 and be discharged.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field.
