Description

Technical Field

[0001] The utility model relates to the technical field of ceramic membranes, in particular to a ceramic filtering membrane. Background Art

[0002] Ceramic membrane is a multifunctional material, mainly made of ceramic powders such as aluminum oxide, silicon oxide, silicon nitride, etc. It has the characteristics of high temperature stability, chemical corrosion resistance, high hardness, high wear resistance and high light transmittance. Ceramic membrane includes multi-channel ceramic membrane, tubular ceramic membrane and plate ceramic membrane. The tubular ceramic membrane can be assembled into a ceramic membrane device through a mold assembly, which can be used to treat extremely poor water quality in recycling projects. Under the action of external pressure, the raw liquid flows in the ceramic membrane channel, small molecules pass through the membrane and form a permeate flow, and suspended large particles are intercepted and form a concentrated liquid that flows back to the raw material box and re-enters the ceramic membrane channel. This cycle continues. As the permeate continues to flow out, the concentration of the intercepted material will gradually increase, and eventually it will be released from the raw material box and the pipeline system, thereby achieving the purpose of separation, concentration and purification.

[0003] The interior of a common ceramic membrane is composed of a series of parallel tiny channels. It uses the principle of molecular sieve, that is, selectively permeating substances of a certain size or shape. When the raw liquid flows in the ceramic membrane channel for a long time, the filter holes are easily blocked. Moreover, the raw liquid flows in a straight line in a single direction, making it difficult to fully contact the filter holes, resulting in low filtration efficiency. Utility Model Content

[0006] Furthermore, a plurality of anti-skid grooves are provided in the middle of the outer surface of the membrane body A, and the plurality of anti-skid grooves are arranged in a circle.

[0007] Furthermore, the membrane body C located below is fixedly connected to the membrane body A, and the membrane body C below is rotatably connected to the membrane body A, and the two are connected to each other.

[0008] Furthermore, the width of the filter element is set to half of the width of the slot, and all of them are spiral-shaped, and the six filter elements are respectively located at the outermost parts of the inner walls of the six slots.

[0009] Furthermore, each of the drainage plates is made of bamboo fiber material, and the height of the drainage plate is equal to the height of the outer circle of the cavity.

[0010] Furthermore, each of the water-permeable nets A, B and C is made of antibacterial fiber material and is fixedly connected to two adjacent drainage plates. The cross section of each water-permeable groove is arc-shaped, and the vertical section is conical.

[0011] Furthermore, the cross section of each of the water-permeable grooves is arc-shaped, and the vertical cross section is conical.

[0012] Compared with the existing technology, the ceramic filter membrane has the following beneficial effects:

[0013] 1. The utility model can increase the contact area between the filter element and the raw liquid by setting the membrane body B and the filter element in a spiral shape, and the membrane body B can rotate forward and reverse, and the two reverse rotations can achieve different effects. The raw liquid is transported from bottom to top. When the membrane body B rotates forward, the membrane body B and the filter element can exert a reverse force on the raw liquid, which can slow down the raw liquid. The centrifugal force generated by the raw liquid during rotation can increase the contact force between the raw liquid and the filter element, thereby improving the filtering effect. The utility model can be suitable for raw liquid with severe pollution, and the raw liquid can exert a force at an inclined angle along the filter element to avoid clogging of the filter pores of the filter element. When the membrane body B reverses, the membrane body B and the filter element can push the raw liquid up, thereby increasing the discharge rate of the raw liquid, thereby increasing the filtration rate. The utility model can be suitable for raw liquid with lighter pollution.

[0014] 2. The utility model sets a deceleration plate. When the water flow is transported from bottom to top, the raw material liquid is transported upward from multiple water-permeable grooves. The deceleration plate can not only separate the raw material liquid in the membrane body A into two parts, which can reduce the flow rate of the water flow, but also block larger foreign matter and prevent the foreign matter from flowing out from the upper membrane body C and increasing the burden on the ceramic filtration device connected to the whole. By setting the cross-sections of multiple water-permeable grooves to be arc-shaped, the water outlet range can be increased. By setting the longitudinal section of the water-permeable groove to be conical, the hydraulic pressure difference between the upper and lower parts of the water-permeable groove can be increased.

[0027] See also Figure 1-9 The utility model provides a technical solution: a ceramic filtration membrane, including a ceramic membrane, the ceramic membrane including a membrane body A1, a membrane body B2 and two membrane bodies C3, the two membrane bodies C3 are symmetrically arranged, the lower membrane body C3 is used for water inlet, and the upper membrane body C3 is used for water outlet, a plurality of anti-skid grooves 12 are opened in the middle of the outer surface of the membrane body A1, the plurality of anti-skid grooves 12 are arranged in a circle, and the whole is installed in a ceramic membrane device, and the grinding wheel in the device is in contact with the membrane body A1, and the grinding wheel is driven by a motor to drive the membrane body A1 to rotate forward and reversely, the lower membrane body C3 is fixedly connected with the membrane body A1, the lower membrane body C3 is rotatably connected with the membrane body A1, and the two are connected with each other, a cavity 4 is opened inside the membrane body A1, the membrane body B2 is located inside the cavity 4, and is connected to the membrane body A1. 1 is fixedly connected, a channel 5 is opened inside the membrane body A1, the membrane body A1 and the channel 5 are both spiral-shaped, the cross-sections of the channel 5 and the membrane body A1 are both hexagonal, the inner wall of the membrane body A1 is opened with six circumferentially arranged notches 6, each notch 6 is spiral-shaped, a filter element 7 is fixedly installed inside each notch 6, the width of the filter element 7 is set to half the width of the notch 6, and all are spiral-shaped, the six filter elements 7 are respectively located at the outermost of the inner walls of the six notches 6, so that the raw material liquid can enter the six notches 6, which is beneficial to the filter element 7 to filter the raw material liquid, a plurality of circumferentially arranged drainage plates 8 are fixedly installed inside the cavity 4, each drainage plate 8 is set to be made of bamboo fiber material, the height of the drainage plate 8 is equal to the height of the outer circle of the cavity 4, and the bamboo fiber The fiber is extracted from naturally grown bamboo, which has a long-lasting and efficient natural antibacterial and bactericidal effect. A plurality of circularly arranged permeable nets A9, B10 and C11 are fixedly installed inside the cavity 4. Each permeable net A9, B10 and C11 is made of antibacterial fiber material and is fixedly connected to two drainage plates 8 adjacent thereto. The antibacterial fiber contains nano-level silver ions and antibacterial ingredients, which can effectively inhibit bacterial growth and reduce odor. In addition, the permeable nets A9, B10 and C11 can slow down the water flow rate, so that the filtered water can fully contact with the plurality of drainage plates 8, thereby improving the purification effect. A deceleration block 14 is fixedly connected to the interior of the membrane body B2. The deceleration block 14 Six water-permeable grooves 15 arranged in a circle are provided inside, and the speed reduction block 14 can reduce the water flow speed, which is conducive to fully filtering the raw material liquid. The raw material liquid at the bottom of the channel 5 can enter its upper part through multiple water-permeable grooves 15. The cross-section of each water-permeable groove 15 is arc-shaped, and the vertical cross-section is conical, which can make the opening at the bottom of the water-permeable groove 15 larger than the opening at the upper part, and its bottom can block larger foreign matter. When the membrane body A is reversed, the raw material liquid flows from top to bottom, increasing the hydraulic pressure difference between the upper and lower parts of the water-permeable groove 15, thereby preventing foreign matter from getting stuck in the water-permeable groove 15 and causing blockage. The outer circle of the bottom surface of the membrane body A1 is provided with multiple drainage holes 13, and the multiple drainage holes 13 are arranged in a circle. The purified water can be discharged through the multiple drainage holes 13.

[0028] When in use, first install the whole in the ceramic membrane device, and make the grinding wheel in the device contact with the membrane body A1, and drive the grinding wheel through the motor, and then drive the membrane body A1 to rotate forward through the friction between the grinding wheel and the membrane body A1, and the membrane body A1 drives the membrane body B2 to rotate, and the membrane body C3 below the membrane body B2 rotates. At this time, the raw liquid is input from the lower membrane body C3, and under the action of external pressure, the raw liquid flows in the ceramic membrane channel 5, and the raw liquid can enter the multiple slots 6, and the raw liquid can contact the filter element 7. Multiple filter elements 7 can filter the raw liquid. The filter element 7 is spiral, which can increase the contact area with the raw liquid, which is beneficial to improving the filtration efficiency. Under the action of external pressure, part of the raw liquid is output from the upper membrane body C3.

[0029] Next, the raw material liquid at the bottom of the channel 5 can enter the upper part thereof through a plurality of water-permeable grooves 15, and the raw material liquid at the bottom of the channel 5 can contact the deceleration plate to reduce the flow rate of the water flow, and can block larger foreign matter to prevent the larger foreign matter from being transported to the upper part of the channel 5. By setting a plurality of water-permeable grooves 15 with arc-shaped cross sections, the contact range between the water-permeable grooves 15 and the raw material liquid can be increased, thereby increasing the water delivery amount of the raw material liquid transported upward. When it is necessary to filter the seriously polluted raw material liquid, the membrane body B2 is driven to rotate forward. According to the spiral design of the membrane body B2, the membrane body B2 and the filter element 7 can filter the raw material liquid. Adding a reverse force can slow down the raw liquid, and the centrifugal force generated by the raw liquid during rotation can increase the contact strength between the raw liquid and the filter element 7, thereby improving the filtering effect. In conjunction with the deceleration of the raw liquid, the raw liquid can be filtered more fully, and the raw liquid can apply an inclined angle force along the filter element 7 to flush out foreign matter that blocks the filter element 7 and avoid clogging of the filter pores of the filter element 7. When it is necessary to filter the lightly contaminated raw liquid, the membrane body B2 is driven to reverse. According to the spiral design of the membrane body B2, the membrane body B2 and the filter element 7 can push the raw liquid up, thereby increasing the discharge rate of the raw liquid and thus increasing the filtration rate.

[0030] Then, the water filtered by the filter element 7 is discharged from the channel 5 and enters the cavity 4 of the membrane body A1. The membrane body A1 can generate centrifugal force when rotating forward and reversely, so that the filtered water can contact with multiple drainage plates 8 and can pass through multiple permeable nets A9, B10 and C11 in sequence. The drainage plate 8 is made of bamboo fiber material, which has a long-lasting and efficient natural antibacterial and bactericidal effect. The permeable nets A9, B10 and C11 are made of antibacterial fiber material, which can effectively inhibit bacterial growth and reduce odor. In this process, the permeable nets A9, B10 and C11 can reduce the flow rate, so that the water can fully contact with the drainage plate 8, thereby improving the purification effect. The purified water is discharged from multiple drainage holes 13.

[0031] Finally, when the filtration work is completed, the membrane body B2 is driven to rotate forward. The membrane body B2 cooperates with multiple filter elements 7 to transport the remaining raw material liquid and foreign matter downward. By setting the longitudinal section of the water-permeable groove 15 to be conical, the hydraulic pressure difference between the top and the bottom of the water-permeable groove 15 can be increased, which is beneficial for the liquid above to flow downward, and can wash away the foreign matter adhering to the bottom of the water-permeable groove 15.
