Description

Technical Field

[0001] This utility model belongs to the technical field of filter equipment components, and in particular relates to a V-shaped adhesive ceramic plate and a ceramic filter for ceramic filter equipment. Background Technology

[0002] Modern society places greater emphasis on environmental protection. In the fields of solid-liquid separation and purification / concentration, the particle size of the filtered materials needs to be increasingly smaller, and the requirements are becoming more stringent. Currently, ceramic filtration equipment is widely used for nanoscale solid-liquid separation. Most ceramic filtration equipment is static filtration equipment with concentration and purification functions.

[0003] Existing ceramic filter equipment uses long, strip-shaped ceramic filter plates with slotted end caps for insertion connections. The joints are bonded together with adhesive to form independent components before being assembled into the ceramic filter equipment. However, the slots at both ends of existing ceramic filter plates are rectangular with flat inner surfaces. Figure 1 As shown, the contact area between the colloid filled in the tank and the ceramic filter plate is small, making it easy for the colloid to delaminate and the ceramic filter plate to detach. This necessitates frequent replacement of the ceramic filter plate assembly, increasing costs and reducing efficiency. This is especially true under harsh filtration conditions where the filtered material contains organic solvents, irritating odors, strong acids, or alkalis, making the ceramic filter plate even more prone to delamination. Therefore, improvements to the existing ceramic filter plate assembly structure are necessary. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a V-shaped adhesive ceramic plate. The technical solution adopted by this utility model is as follows:

[0005] A V-shaped adhesive ceramic plate includes a ceramic filter plate and a head. The ceramic filter plate has a plate-like structure and multiple flow channels inside, which extend along the length of the ceramic filter plate. The head has a slot inside, with the inner walls on both sides of the slot protruding inward to form an inner V-shape and an outer V-shape, or the inner cavity of the slot has a frustum-shaped structure. Both ends of the ceramic filter plate are inserted into the head. The inner wall of the slot and the ceramic filter plate are filled with a colloid, and the ceramic filter plate and the head are fixedly connected by the colloid. At least one end of the ceramic filter plate has a liquid outlet channel and a liquid outlet interface at the bottom of the head slot. The liquid outlet channel extends along the width of the ceramic filter plate, and the liquid outlet interface communicates with the liquid outlet channel and the flow channels.

[0006] The technical effects achieved by employing the aforementioned technical features are as follows:

[0007] The ceramic filter plate of this invention features a double-V structure, with the inner walls of the slots at both ends of the end caps protruding inwards to form an inner V-shape and an outer V-shape, or a single V-shape with a frustum-shaped inner cavity. This increases the bonding area between the colloid and the ceramic filter plate, making it less prone to separation and detachment. When filtering under harsh conditions such as organic solvents, irritating odors, strong acids, or strong alkalis, the adhesive in the V-shaped area in contact with the filtered material is corroded and passivated, forming a passivation layer. The adhesive inside the V-shape, which is not in contact with the material, retains its adhesive strength and is less likely to change. This V-shaped structure extends the service life of the V-shaped bonded ceramic plate, reduces the frequency of replacement, lowers costs, and improves work efficiency. The slots with liquid outlet ports have a continuous liquid outlet channel at the bottom, further increasing the filtration rate.

[0008] During use, the surface of the ceramic filter plate is densely covered with micropores. Within a certain pore size range, the permeability varies depending on the diameter of the molecules of the permeating substances. Driven by the pressure difference across the ceramic filter plate, the ceramic filter plate serves as the filter medium. Under a certain pressure, when the liquid flows across the surface of the ceramic filter plate, only water, inorganic salts, and small molecules are allowed to pass through to the internal guide channel of the ceramic filter plate. They then converge into the interconnected outlet channel at the bottom of the slot and flow out from the outlet port of the ceramic filter plate. Solid insoluble suspended solids, colloids, microorganisms, and other large molecules in the material are trapped on the surface of the ceramic filter plate, forming a solid accumulation of 5-10 mm thickness, thereby achieving the filtration or concentration of the material.

[0009] This technical solution can also be improved in the following ways:

[0010] Furthermore, the liquid outlet interface is provided with threads inside or outside. Threaded liquid outlet interfaces offer better fastening performance and stronger sealing.

[0011] Furthermore, the end cap is made of metal or non-metal. The material of the end cap can be customized according to the usage environment, making it highly adaptable.

[0012] Furthermore, the protrusion is a prismatic protrusion or an arc-shaped protrusion.

[0013] Furthermore, the protrusions are wavy. This further increases the bonding area between the colloid and the ceramic filter plate, making it less likely for the ceramic filter plate to come off.

[0014] Furthermore, the flow channel is a square or circular channel.

[0015] Furthermore, the bottom of the end cap slot is flat, or the bottom of the end cap slot at at least one end of the ceramic filter plate is arc-shaped.

[0016] The bottom of the end cap slot is arc-shaped, which can increase the space of the liquid outlet channel, increase the liquid outlet rate, and thus increase the filtration rate.

[0017] Furthermore, the colloid is a two-component adhesive.

[0018] The V-shaped adhesive ceramic plate provided by this utility model has a double V-shaped structure with the inner walls of the slots at both ends of the ceramic filter plate protruding inward to form an inner V-shape and an outer V-shape, or a single V-shaped structure with the inner cavity of the slot being a frustum. This increases the service life of the V-shaped adhesive ceramic plate, reduces the frequency of replacing the V-shaped adhesive ceramic plate, lowers costs, and improves work efficiency. The slots with liquid outlets have a connected liquid outlet channel at the bottom, which improves the filtration rate. The threaded liquid outlet has good fastening performance and stronger sealing.

[0036] like Figures 2-6 As shown, the V-shaped adhesive ceramic plate of this embodiment includes a ceramic filter plate 2 and end caps, the end caps including a left end cap 3 and a right end cap 4. The ceramic filter plate 2 has a plate-like structure, and the ceramic filter plate 2 has multiple flow channels 7 inside, the flow channels 7 being square or circular channels. In this embodiment, the flow channels 7 are square channels, and the flow channels 7 extend along the length direction of the ceramic filter plate 2. The left end cap 3 and the right end cap 4 have slots inside, and the inner walls on both sides of the slots protrude inward to form an inner V-shape and an outer V-shape. In this embodiment, the protrusions are prismatic protrusions. The end caps are inserted into both ends of the ceramic filter plate 2, and a certain gap is left between the protrusions and the ceramic filter plate 2. The inner wall of the slot and the ceramic filter plate 2 are filled with colloid 8, and the ceramic filter plate 2 and the end caps are fixedly connected by the colloid 8. In this embodiment, the colloid 8 is a two-component adhesive E-120HP epoxy resin structural adhesive. The left end cap 3 at one end of the ceramic filter plate 2 is provided with a liquid outlet interface 5, and the liquid outlet interface 5 has internal threads. A liquid outlet channel 6 is provided at the bottom of the slot of the left end cap 3, extending along the width direction of the ceramic filter plate 2, and communicating with the guide channel 7 and the liquid outlet interface 5. The end cap can be made of metal or non-metal, and the material can be customized according to the usage environment, exhibiting high adaptability. In this embodiment, a metal material is used.

[0037] Example 2:

[0038] like Figure 7As shown, the V-shaped adhesive ceramic plate of this embodiment differs from that of Embodiment 1 in that the left end cap 3 and the right end cap 4 of the ceramic filter plate 2 are both provided with liquid outlet ports 5, and the bottom of the slots of the left end cap 3 and the right end cap 4 are both provided with liquid outlet channels 6.

[0039] Example 3:

[0040] like Figure 8 As shown, the V-shaped adhesive ceramic plate of this embodiment differs from that of Embodiment 1 in that the bottom of the slot of the left end cap 3 of the ceramic filter plate 2 is arc-shaped.

[0041] Example 4:

[0042] like Figure 9 As shown, the V-shaped adhesive ceramic plate of this embodiment differs from that of Embodiment 1 in that the bottom of the slots of the left end cap 3 and the right end cap 4 of the ceramic filter plate 2 are both arc-shaped.

[0043] Example 5:

[0044] like Figures 10-11 As shown, the V-shaped adhesive ceramic plate of this embodiment differs from that of Embodiment 1 in that the slot cavities of the left end cap 3 and the right end cap 4 have a frustum structure, i.e., a single V-shaped structure.

[0045] Example 6:

[0046] The V-shaped adhesive ceramic plate of this embodiment differs from that of Embodiment 1 in that the bottom of the slot of the right end cap 4 of the ceramic filter plate 2 is arc-shaped.

[0047] Example 7:

[0048] The V-shaped adhesive ceramic plate of this embodiment differs from that of embodiment 4 in that both the left end cap 3 and the right end cap 4 of the ceramic filter plate 2 are provided with liquid outlet ports 5, and both the bottom of the slots of the left end cap 3 and the right end cap 4 are provided with liquid outlet channels 6.

[0049] like Figure 12 As shown, during use, multiple V-shaped bonded ceramic plates 1 are circumferentially arranged on the rotating support of the ceramic filter. During material filtration, the surface of the ceramic filter plate 2 is densely covered with micropores. Within a certain pore size range, the permeability varies depending on the diameter of the permeating molecules. Driven by the pressure difference across the ceramic filter plate 2, and using the ceramic filter plate 2 as the filter medium, under a certain pressure, when the liquid flows across the surface of the ceramic filter plate 2, only water, inorganic salts, and small molecules are allowed to pass through to the internal guide channel 7 of the ceramic filter plate 2. These then converge into the connecting outlet channel 6 at the bottom of the slot and flow out from the outlet port 5 of the ceramic filter plate 2. Solids insoluble in water, colloids, and large molecules such as microorganisms are trapped on the surface of the ceramic filter plate 2, forming a solid accumulation of 5-10 mm thickness, thus achieving the filtration or concentration of the material.

[0050] The ceramic filter plate 2 of this invention features a double V-shaped structure, with the inner walls of the slots at both ends of the end caps protruding inwards to form an inner V-shape and an outer V-shape, or a single V-shaped structure with a frustum-shaped inner cavity. This increases the bonding area between the colloid 8 and the ceramic filter plate 2, making it less prone to separation and detachment. During filtration under harsh conditions such as organic solvents, irritating odors, strong acids, and strong alkalis, the V-shaped adhesive in contact with the filtered material is corroded and passivated, forming a passivation layer. The adhesive inside the V-shape, which is not in contact with the material, retains its adhesive strength and is less likely to change. This V-shaped structure extends the service life of the V-shaped bonded ceramic plate 1, reduces the frequency of replacement, lowers costs, and improves work efficiency. The slot with the outlet port 5 has a continuous outlet channel 6 at the bottom, improving the filtration rate. The threaded outlet port 5 provides good fastening performance and stronger sealing.
