Description

Technical Field

[0001] The invention relates to the field of sewage purification, and in particular to a purification treatment device based on a ceramic membrane. Background Art

[0002] Ceramic membrane is an effective purification element for sewage, which can filter out harmful substances such as rust, silt, suspended matter, colloids, bacteria, macromolecular organic matter, etc. in water. For example, Chinese patent with publication number: CN117566956A discloses an intelligent ultrafiltration membrane water treatment device, which sets an ultrafiltration mechanism and a drug delivery mechanism and links them together. When the ultrafiltration net is blocked, the gradually increasing water pressure in the ultrafiltration box is utilized to achieve the switching between water injection and drug injection. At the same time, the potential energy of the drug falling during drug injection is used to drive the pumping box to continuously extract and press out the drug, and the ultrafiltration membrane is backwashed through the nozzle, thereby greatly improving the cleaning efficiency and effect of ultrafiltration.

[0003] However, when the ultrafiltration membrane is immersed in water for cleaning, it is necessary to stop purifying the sewage and wait until the ultrafiltration membrane is cleaned before continuing to purify the sewage, which greatly reduces the purification efficiency of the sewage.

The partition 102 is fixed; each bottom plate 105 is fixed with a valve 106; the box body 1 is connected to two ultrafiltration membranes 107 distributed on the left and right, and the ultrafiltration membrane 107 is connected to the partition 102, and the ultrafiltration membrane 107 is located between the corresponding rectangular plate 103 and the bottom plate 105; each bottom plate 105 is fixed with an electrode 108, and each rectangular plate 103 is fixed with another electrode 108; the box body 1 is fixed with two pipes 1015, and the pipes 1015 are located near the corresponding bottom plates 105; the box body 1 is connected with a coarse filtration component for coarse filtration of sewage; the box body 1 is connected with a diversion component for diverting sewage.

[0022] It also includes a cover shell 109, an electric push rod 1010, a reinforcing plate 1016 and a connecting rod 1011; the baffle 101 is fixedly connected to two cover shells 109; each cover shell 109 is bolted with an electric push rod 1010; the telescopic end of each electric push rod 1010 is fixedly connected to a connecting rod 1011; each connecting rod 1011 is fixedly connected to a reinforcing plate 1016, and the ultrafiltration membrane 107 is installed in the corresponding reinforcing plate 1016, and the reinforcing plate 1016 is slidably connected to the box body 1.

[0023] Several rubber sealing rings are arranged on the side of the ultrafiltration membrane 107 to enhance the sealing between the ultrafiltration membrane 107 and the housing 1 and prevent sewage from leaking from the gap between the ultrafiltration membrane 107 and the housing 1 .

[0024] The flow splitter assembly includes an electric shaft 1012, a connecting disk 1013 and a flow splitter plate 1014; the housing 1 is rotatably connected to the electric shaft 1012; the electric shaft 1012 is fixedly connected to the connecting disk 1013; the connecting disk 1013 is fixedly connected to the flow splitter plate 1014 with a V-shaped cross section.

[0025] The baffle 101 is arranged in a V shape to guide the sewage to the rectangular groove 1001 and reduce the sewage residue on the baffle 101 .

[0026] It also includes a drug inlet pipe 1017 ; the box body 1 is fixedly connected to two drug inlet pipes 1017 , and the drug inlet pipes 1017 are located close to the corresponding rectangular plate 103 .

[0027] When in use, first connect the external sewage pipe to the water inlet hopper 3, the external suction pump to the pipeline 1015, and the external pump to the medicine inlet pipe 1017, and then control the external sewage pipe to input the sewage from the water inlet hopper 3 into the box body 1. The sewage first passes through the coarse filtration of the coarse filtration component to filter out the silt and larger impurities. The sewage after coarse filtration flows to the baffle 101, and then the sewage flows from the rectangular groove 1001 to the diverter plate 1014. Subsequently, the sewage enters the two rectangular plates 103 after being diverted by the diverter plate 1014. After the sewage gathers on the upper side of the rectangular plate 103, control the water inlet pump 104 to pump the sewage gathered on the upper side of the rectangular plate 103 onto the ultrafiltration membrane 107 for filtration. The filtered sewage flows to the bottom plate 105 and flows out of the box body 1 from the opened valve 106, completing the filtration and purification of the sewage.

[0028] After long-term use, more impurities will adhere to the surface of the ultrafiltration membrane 107, which will cause the ultrafiltration membrane 107 to be blocked, affecting the purification and filtering effect of sewage. For example, when the ultrafiltration membrane 107 on the left side needs to be cleaned, the electric shaft 1012 is controlled to drive the connecting plate 1013 and the diverter plate 1014 to rotate as shown in the figure. Figure 4As shown, the diverter plate 1014 only directs the sewage to the ultrafiltration membrane 107 on the right side for filtration treatment. At this time, the water inlet pump 104 stops pumping the sewage on the upper side of the rectangular plate 103 to the ultrafiltration membrane 107, and closes the valve 106. Then, the electric push rod 1010 is controlled to make the connecting rod 1011 and the reinforcing plate 1016 drive the ultrafiltration membrane 107 to move downward until the ultrafiltration membrane 107 contacts the bottom plate 105, so that the ultrafiltration membrane 107 contacts the bottom plate 105. The water on the upper side of the plate 105 is squeezed, and the water flows through the ultrafiltration membrane 107 to the upper side of the ultrafiltration membrane 107, so that the water on the upper side of the bottom plate 105 backwashes the ultrafiltration membrane 107, and the impurities on the ultrafiltration membrane 107 are flushed out to the upper side of the ultrafiltration membrane 107, and then the ultrafiltration membrane 107 is backwashed and cleaned. Then, the external suction pump is controlled to start, and the sewage with impurities on the upper side of the ultrafiltration membrane 107 is pumped out through the pipeline 1015, and then the pipeline 1015 is closed; Next, the external pump is controlled to start, and the salt water is transported between the rectangular plate 103 and the upper side of the ultrafiltration membrane 107 through the drug inlet pipe 1017, so that the salt water soaks the ultrafiltration membrane 107. Next, the electrode 108 is energized to make the electrode 108 electrolyze the salt water, and the hypochlorite ions generated by the electrolysis of the salt water soak the ultrafiltration membrane 107, thereby sterilizing and purifying the ultrafiltration membrane 107. In the sterilization and purification process, the electric push rod 1010 is controlled to make the connecting rod 1011 and the reinforcing rod 1010 Plate 1016 drives the ultrafiltration membrane 107 to move vertically, so that the ultrafiltration membrane 107 is rinsed in the electrolyzed sterilizing liquid, thereby improving the immersion and cleaning efficiency of the ultrafiltration membrane 107. After the immersion is completed, the valve 106 is opened, and then the electric push rod 1010 is controlled to make the connecting rod 1011 and the reinforcing plate 1016 drive the ultrafiltration membrane 107 to move upward until the ultrafiltration membrane 107 contacts the lower side of the rectangular plate 103, so that the sterilizing liquid after immersion passes through the ultrafiltration membrane 107 and flows out from the opened valve 106.

[0029] Similarly, when the ultrafiltration membrane 107 on the right side needs to be cleaned, the electric shaft 1012 is controlled to drive the connecting disk 1013 and the diverter plate 1014 to rotate, so that the diverter plate 1014 only diverts the sewage to the ultrafiltration membrane 107 on the right side for filtration treatment. When the amount of sewage is large, the electric shaft 1012 is controlled to drive the connecting disk 1013 and the diverter plate 1014 to rotate, so that the diverter plate 1014 diverts the sewage to the two ultrafiltration membranes 107 for filtration at the same time, thereby greatly improving the filtration and purification efficiency of the sewage.

[0030] Example 2 On the basis of Example 1, Figure 2 and Figure 3As shown, the coarse filtration assembly includes a coarse filter plate 201, a hydraulic rod 202, a wedge plate 203, a spring rod 204 and a limit plate 205; the cover plate 2 is provided with a slide groove 21; the coarse filter plate 201 is slidably connected in the box body 1; the box body 1 is bolted with the hydraulic rod 202, and the telescopic end of the hydraulic rod 202 passes through the box body 1 and is fixedly connected to the coarse filter plate 201; the coarse filter plate 201 is fixedly connected to two wedge plates 203; the water inlet bucket 3 is fixedly connected to a plurality of spring rods 204; the telescopic ends of all the spring rods 204 are commonly fixedly connected to the limit plate 205, and the limit plate 205 is slidably connected to the water inlet bucket 3.

[0031] A scraper bar is provided at the edge of the coarse filter plate 201 , and when the coarse filter plate 201 moves vertically along the inner wall of the box body 1 , the scraper bar on the edge of the coarse filter plate 201 scrapes off the dirt adhered to the inner wall of the box body 1 .

[0032] Initially, the coarse filter plate 201 is located near the baffle 101, and the mouth of the water inlet hopper 3 is smaller after the limit plate 205 covers and limits the water inlet hopper 3, so that under the premise that the water inlet hopper 3 maintains the same sewage flow rate, the sewage flow rate flowing through the mouth of the water inlet hopper 3 is greater, and then the flow rate of the sewage when passing through the coarse filter plate 201 is greater, which increases the impact force on the coarse filter plate 201, prevents microorganisms from depositing on the surface of the coarse filter plate 201 from the beginning and forming a biofilm, causing the coarse filter plate 201 to be blocked. As the coarse filter plate 201 continues to filter the sewage, impurities such as silt gather on the coarse filter plate 201. In order to prevent the large water flow impact force from impacting the mud and the like on the coarse filter plate 201 downward onto the baffle 101, therefore, after a predetermined filtering time, the hydraulic rod 202 is controlled to drive the coarse filter plate 201 and the wedge plate 203 to move upward, the wedge plate 203 enters the chute 21, and then the wedge plate 203 pushes the limit plate 205 to move left, the spring rod 204 is stretched, so that the limit plate 205 reduces the degree of limitation on the water inlet bucket 3, the bucket mouth of the water inlet bucket 3 is enlarged, the flow rate of the sewage flowing through the bucket mouth of the water inlet bucket 3 is reduced, and the impact force on the coarse filter plate 201 is reduced.

[0033] Example 3 On the basis of Example 2, Figure 3-Figure 4 As shown, a collecting bucket 301 is also included; the box body 1 is provided with the collecting bucket 301, and the collecting bucket 301 is located below the bottom plate 105.

[0034] It also includes a sealing plate 302; the reinforcing plate 1016 is detachably connected to the ultrafiltration membrane 107; the box body 1 is detachably connected to two sealing plates 302, and the sealing plates 302 are located between the corresponding rectangular plate 103 and the bottom plate 105.

[0035] After the two ultrafiltration membranes 107 purify the sewage, the clean water flows out from the two valves 106 and is collected in the collecting bucket 301 to flow out of the box 1, thereby reducing the use of two collecting pipes to collect the outflow from the two valves 106 separately, saving costs, and when the ultrafiltration membrane 107 needs to be replaced, the electric push rod 1010 is controlled to make the connecting rod 1011 drive the reinforcing plate 1016 and the ultrafiltration membrane 107 to move upward until the ultrafiltration membrane 107 and the sealing plate 302 are flush, and the sealing plate 302 is manually removed from the box 1, and then the ultrafiltration membrane 107 is removed from the reinforcing plate 1016 for replacement, which is convenient and quick.
