Description

Technical Field

[0001] The invention relates to the technical field of mesoporous felt production, in particular to a mesoporous felt impregnation device with an immersion degree detection function. Background Art

[0002] In the production process of mesoporous felt, fiber felt that already has a microporous structure is used as raw material. After impregnation, hot air curing, aging modification, hot air drying, surface tension modification, and hot air drying again, a mesoporous felt with the expected mechanical strength and chemical resistance is obtained. Among them, the impregnation is to use resin or other glue for impregnation treatment. The glue fully covers the entire surface of the mesoporous felt, and the micropores and fiber surfaces must also be fully impregnated. Subsequent curing and other processes can be carried out. Otherwise, the obtained mesoporous felt is prone to quality problems and cannot achieve the target performance.

[0003] In the existing technology, the dipping process generally involves placing the raw felt into the glue solution, waiting for a period of time, taking it out and directly sending it to the subsequent curing process. The defects of insufficient dipping in some microscopic positions cannot be perceived in time. In terms of promoting the adequacy of dipping, only simple methods such as vacuum negative pressure are used, which easily leads to insufficient dipping. The problem is not discovered until the performance test link after the mesoporous felt is produced, wasting a lot of mechanical operation resources from the dipping link to the completion of production. Summary of the Invention

[0004] The object of the present invention is to provide a mesoporous felt impregnation device with an immersion degree detection function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions: A mesoporous felt dipping device with a dipping degree detection function includes a dipping table, a dipping seat, and a detection component. The dipping table is provided with a dipping seat, and the detection component is provided on one side of the dipping seat in a horizontal direction. The mesoporous felt to be treated enters the dipping seat and then detaches from the dipping seat from one side of the detection component. A glue solution containing carbon nanotubes or graphene is injected into the dipping seat, and the detection component detects whether the resistivity of the mesoporous felt in the width direction is uniform after dipping.

[0006] The rolled semi-finished mesoporous material is used as the raw material for the production of mesoporous felt. Whether the previous process of impregnation is uniform and sufficient will significantly affect the quality of the subsequent processes. The present application adds carbon nanotubes or graphene to the glue to improve the conductivity of the glue. Before the glue is dried and solidified, the colloidal glue wets all the fiber structures on the mesoporous felt. If the local position is not wetted, there will be a relatively obvious change in the conductivity percentage when passing through the detection part. This is used as a basis for whether the impregnation is sufficient. The mesoporous felt that is not sufficiently and uniformly impregnated can be returned to the impregnation seat for repeated impregnation, and the detection part is detected through electrical contact.

[0007] The glue dipping seat includes a glue box, a glue port, and an ultrasonic port. The glue box is placed on the glue dipping table. The glue port and the ultrasonic port are set on the lower wall of the glue box. The glue port is used to inject new glue from the outside, and the ultrasonic port is directly facing the mesoporous felt entering the glue box from bottom to top.

[0008] The ultrasonic port emits ultrasonic waves during the dipping process to promote the glue to infiltrate the microporous wall of the mesoporous felt. The bottom of the upper glue port is connected to the glue supply component at the bottom of the dipping table, such as a gear pump. After one dipping is completed, the liquid supply component sends the glue required for the next cycle of operation into the glue box through the upper glue port. The ultrasonic port emits ultrasonic waves vertically upward to directly hit the lower surface of the mesoporous felt, causing micro-vibration.

[0009] There are several ultrasonic ports distributed in an array on the bottom surface of the glue box. The ultrasonic ports are in an inward trumpet shape with a larger inner side and a smaller outer side.

[0010] There are multiple ultrasonic ports that emit ultrasonic waves toward the mesoporous felt in the wetting process, so that the mesoporous felt can directly feel the ultrasonic waves over a larger area, which can further improve the uniformity and sufficiency of the immersion. Because the ultrasonic port in this application is very close to the mesoporous felt to be impacted, there is no need for a traditional outward trumpet-shaped port to release sound waves over a long distance. Instead, it is necessary to allow the ultrasonic waves to impact the entire surface of the mesoporous felt as much as possible. Therefore, the trumpet port of this application faces inward, and the tapered port increases the diffraction degree of the sound wave when it is released from the ultrasonic port, thereby increasing the effective area within a short spatial range. It is not necessary to set up many ultrasonic ports to fully cover the surface of the mesoporous felt, thereby improving the wetting effect.

[0011] The dipping equipment also includes a guide roller and a traction roller. The guide roller and the traction roller are respectively arranged on both sides of the dipping table. The guide roller is located between the dipping table and the mesoporous felt raw material roll, and the traction roller runs intermittently.

[0012] The traction roller runs intermittently to allow the mesoporous felt to advance periodically, and the impregnation operation is carried out in sections. After each operation cycle, the traction roller pulls the mesoporous felt forward to detect changes in the conductivity of the inspected part in the width direction. If the impregnation is insufficient, the mesoporous felt needs to be pulled back for a second impregnation operation.

[0013] The dipping equipment also includes a support frame and a pressing plate. The support frame is set on the dipping table. The vertically moving pressing plate is installed on the support frame. The pressing plate covers the glue box from top to bottom. The pressing plate also presses the position where the mesoporous felt enters and exits the glue box and seals it. During a single dipping process, a closed chamber is constructed between the pressing plate and the glue box.

[0014] The pressure plate and the glue box are sealed, and the internal glue and mesoporous felt impregnation process can enhance the wetting effect by changing the pressure. Traditionally, negative pressure is generally used to promote impregnation. In addition, a larger positive pressure can also promote the flow of glue in the micropores. The main principle is that the volume of the internal micropores increases or decreases after the pressure changes. The increase in gas volume may develop into bubbles and float up. When the gas volume decreases, the glue replaces the position originally occupied by the gas for wetting. Even if the pressure returns to normal atmospheric pressure, the glue that has adhered to the micropore wall will no longer be squeezed out by the gas due to adhesion. Therefore, a simple larger positive pressure or negative pressure can promote the wetting effect.

[0015] The dipping equipment also includes a hydraulic oscillation component, which is arranged on the side wall of the glue box. The hydraulic pressure in the closed chamber between the pressure plate and the glue box oscillates, and the oscillation frequency is a multiple of the ultrasonic frequency emitted by the ultrasonic port.

[0016] The hydraulic pressure of the glue liquid oscillates and changes, and the gas clusters in the micropores inside the mesoporous felt that have not yet been soaked change in size. The change cycle is consistent with the hydraulic oscillation cycle. At this time, the vibration cycle of the mesoporous felt and glue liquid stimulated by ultrasound is consistent with the ultrasonic frequency. The frequencies of the two are in a multiple relationship, which means that there is always a time when superposition occurs. When the two factors are superimposed, the effect of the tiny air clusters detaching from the micropore walls inside the mesoporous felt can be improved, thereby promoting the soaking effect.

[0017] The hydraulic oscillation component includes a connecting box, an extension head, and an axial extrusion piece. The connecting box is fixed on the side wall of the glue box and is connected to the space inside the glue box through a through hole. Multiple extension heads are arranged on the outer wall of the connecting box, and an axial extrusion piece is arranged at the end of the extension head. The multiple axial extrusion pieces apply force to the liquid in the extension head at the same frequency and phase.

[0018] Axial extrusion components simultaneously squeeze and release the internal liquid through multiple extensions. Small oscillations require less inertia to overcome and are relatively easy to achieve. Multiple small hydraulic oscillations, as long as they are in phase, can create relatively significant pressure changes within the connecting box, which are then transmitted to the dipping space between the pressure plate and the glue box. Ideally, axial extrusion components only experience axial deformation, and internal hydraulic pressure does not cause expansion in the outer diameter direction. For example, when using bellows, the components are manufactured.

[0019] The hydraulic oscillation component also includes several force-bearing columns and several force-applying columns. The force-bearing columns are installed at the ends of the outer walls of the axial extrusion parts, and the force-applying columns are arranged on fixed brackets extending from the inside of the dipping table. The force-bearing columns and the force-applying columns perform periodic oscillation and force application through electromagnetic action. The frequency phase of the electrical signals introduced into all the force-applying columns after modulation is the same.

[0020] The force-applying column can be an electromagnet. By inputting an electrical signal, it periodically generates suction and repulsion on the force-bearing column, driving the axial extrusion part to perform small periodic oscillations to produce an extrusion effect. Electrical signals are relatively easy to control the operating waveform, while mechanical oscillations are difficult to increase the frequency and control the frequency accuracy. Relatively speaking, the smaller the multiple of the ultrasonic frequency emitted by the ultrasonic port and the oscillation frequency of the glue hydraulic pressure, the easier it is to generate resonance and promote glue impregnation. However, the frequency of hydraulic pressure change is limited by a large range of physical media and the inertia of the working components that drive the hydraulic pressure change. It is difficult to continuously improve, so it can only be selected in a multiple relationship.

[0021] The hydraulic oscillation component also includes a balance spring, one end of which is against the end of the axial extrusion piece. The preload force in the balance spring is equal to the pressure of the pressure reference value in the glue box acting on the axial extrusion piece.

[0022] The hydraulic reference value multiplied by the end face area of ​​the axial extrusion part is equal to the preload force of the balance spring. In this way, the suction and repulsion between the load-bearing column and the force-applying column can oscillate around the zero-line reference value. There is no need for waveform compensation and overall translation on the modulated electrical signal of the force-applying column, reducing the difficulty of control.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: carbon nanotubes and other highly conductive materials are added to the glue solution of the present invention, so that the mesoporous felt after impregnation is electrically contacted with two roller brushes arranged in the width direction, and the electrical signal in the width direction is detected to judge the sufficiency and uniformity of impregnation. The mesoporous felt that exceeds the design expectations is returned to the glue box for secondary processing and testing; the impregnation process combines the two factors of ultrasound and pressure oscillation, so that the gas in the micropores of the mesoporous felt can quickly separate from the pore wall and the microscopic fiber surface under the combined action, thereby improving the impregnation effect. The necking design at the ultrasonic port can expand the degree of diffraction, and the sound waves emitted by a small number of distributed ultrasonic ports can fully cover the entire surface of the mesoporous felt.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] A mesoporous felt dipping device with a dipping degree detection function, the dipping device includes a dipping table 2, a dipping seat 5, and a detection component 6. The dipping table 2 is provided with the dipping seat 5, and the detection component 6 is provided on one side of the dipping seat 5 in a horizontal direction. The mesoporous felt 9 to be treated enters the dipping seat 5 and then separates from the dipping seat 5 from one side of the detection component 6; the dipping seat 5 is injected with glue containing carbon nanotubes or graphene, and the detection component 6 detects whether the resistivity of the mesoporous felt 9 in the width direction is uniform after dipping.

[0027] like Figure 1 、 2 As shown, the rolled semi-finished mesoporous material is used as the raw material for the production of mesoporous felt. Whether the glue impregnation in the previous process is uniform and sufficient will significantly affect the quality of the subsequent processes. The present application adds carbon nanotubes or graphene to the glue to improve the conductivity of the glue. Before the glue is dried and solidified, the colloidal glue wets all the fiber structures on the mesoporous felt. If the local position is not wetted, there will be a relatively obvious change in the conductivity percentage when passing through the detection part 6. This is used as a basis for whether the impregnation is sufficient. The mesoporous felt that is not sufficiently and uniformly impregnated can be returned to the impregnation seat 5 for repeated impregnation, and the detection part 6 performs detection through electrical contact.

[0028] The glue dipping seat 5 includes a glue box 51, a glue port 52, and an ultrasonic port 53. The glue box 51 is placed on the glue dipping table 2. The glue port 52 and the ultrasonic port 53 are set on the lower wall of the glue box 51. The glue port 52 is used to inject new glue from the outside, and the ultrasonic port 53 is directly facing the mesoporous felt 9 entering the glue box 51 from bottom to top.

[0029] like Figure 1 、 3As shown, the ultrasonic port 53 emits ultrasonic waves during the dipping process to promote the glue to infiltrate the microporous wall of the mesoporous felt. The bottom of the upper glue port 52 is connected to the glue supply component at the bottom of the dipping table 2, such as a gear pump. After one dipping is completed, the liquid supply component sends the glue required for the next cycle of operation into the glue box 51 through the upper glue port 52. The ultrasonic port 53 emits ultrasonic waves vertically upward to directly hit the lower surface of the mesoporous felt 9, causing micro-vibration.

[0030] There are a plurality of ultrasonic ports 53 on the bottom surface of the glue container 51 and they are distributed in an array. The ultrasonic ports 53 are in the shape of an inward trumpet with a larger inner portion and a smaller outer portion.

[0031] like Figure 1 、 3 As shown, the ultrasonic port 53 has multiple ultrasonic ports that respectively emit ultrasonic waves toward the mesoporous felt 9 in the infiltration process, so that the mesoporous felt 9 can directly feel the ultrasonic waves over a larger area, which can further improve the uniformity and sufficiency of the immersion. Because the ultrasonic port 53 in the present application is very close to the mesoporous felt to be impacted, there is no need for a traditional outward trumpet-shaped port to release sound waves over a long distance. Instead, it is necessary to allow the ultrasonic waves to impact the entire surface of the mesoporous felt 9 as much as possible. Therefore, the trumpet port of the present application faces inward, and the tapered port increases the diffraction degree of the sound waves when they are released from the ultrasonic port 53, thereby increasing the effective area within a short spatial range. There is no need to set up many ultrasonic ports 53 to fully cover the surface of the mesoporous felt 9, thereby improving the infiltration effect.

[0032] The dipping equipment also includes a guide roller 1 and a pulling roller 7. The guide roller 1 and the pulling roller 7 are respectively arranged on both sides of the dipping table 2. The guide roller 1 is located between the dipping table 2 and the mesoporous felt 9 raw material roll, and the pulling roller 7 runs intermittently.

[0033] like Figure 1 、 2 As shown, the traction roller 7 runs intermittently to allow the mesoporous felt 9 to advance periodically, and the impregnation operation is carried out in sections. After each operation cycle, the traction roller 7 pulls the mesoporous felt 9 forward and the detected part 6 detects the change in conductivity in the width direction. If the impregnation is insufficient, the mesoporous felt 9 needs to be pulled back for a second impregnation operation.

[0034] The dipping equipment also includes a support frame 3 and a pressing plate 4. The support frame 3 is arranged on the dipping table 2. The vertically movable pressing plate 4 is installed on the support frame 3. The pressing plate 4 covers the glue box 51 from top to bottom. The pressing plate 4 also presses the position where the mesoporous felt 9 enters and exits the glue box 51 and seals it. During a single dipping process, a closed chamber is constructed between the pressing plate 4 and the glue box 51.

[0035] like Figure 1 、 2As shown in Figure 3, the pressure plate 4 and the glue box 51 are sealed, and the internal glue and the mesoporous felt 9 can be impregnated during the process to enhance the wetting effect by changing the pressure. Traditionally, negative pressure is generally used to promote impregnation. In addition, a larger positive pressure can also promote the flow of glue in the micropores. The main principle is that the volume of the internal micropores increases or decreases after the pressure changes. The increase in gas volume may develop into bubbles and float up. When the gas volume decreases, the glue replaces the position originally occupied by the gas for wetting. Even if the pressure returns to normal atmospheric pressure, the glue that has adhered to the wall of the micropores will no longer be squeezed out by the gas due to adhesion. Therefore, a simple larger positive pressure or negative pressure can promote the wetting effect.

[0036] The dipping device further comprises a hydraulic oscillating component 8 , which is arranged on the side wall of the glue box 51 . The hydraulic pressure in the closed chamber between the pressing plate 4 and the glue box 51 oscillates, and the oscillation frequency is a multiple of the ultrasonic frequency emitted by the ultrasonic port 53 .

[0037] The hydraulic pressure of the glue liquid oscillates and changes, and the gas clusters in the micropores inside the mesoporous felt that have not yet been soaked change in size. The change cycle is consistent with the hydraulic oscillation cycle. At this time, the vibration cycle of the mesoporous felt and glue liquid stimulated by ultrasound is consistent with the ultrasonic frequency. The frequencies of the two are in a multiple relationship, which means that there is always a time when superposition occurs. When the two factors are superimposed, the effect of the tiny air clusters detaching from the micropore walls inside the mesoporous felt can be improved, thereby promoting the soaking effect.

[0038] The hydraulic oscillation component 8 includes a connecting box 81, an extension head 82, and an axial extrusion piece 83. The connecting box 81 is fixed on the side wall of the glue box 51 and is connected to the space inside the glue box 51 through a through hole. Multiple extension heads 82 are set on the outer wall of the connecting box 81, and axial extrusion pieces 83 are set at the ends of the extension heads 82. The multiple axial extrusion pieces 83 apply force to the liquid in the extension heads 82 at the same frequency and phase.

[0039] like Figure 3 、 4 As shown, the axial extrusion member 83 simultaneously squeezes and releases the internal liquid through multiple extension heads 82. Small oscillations require less inertia to overcome and are relatively easier to achieve. Multiple small hydraulic oscillations, as long as they are in phase, can cause relatively significant pressure changes in the connecting box 81, which are then transmitted to the dipping space between the pressure plate 4 and the glue box 51. Ideally, the axial extrusion member 83 only undergoes deformation due to axial extrusion, and the internal hydraulic pressure does not cause expansion in the outer diameter direction. For example, it can be made of a bellows.

[0040] The hydraulic oscillation component 8 also includes a plurality of force-bearing columns 85 and a plurality of force-applying columns 86. The force-bearing columns 85 are installed at the ends of the outer walls of the axial extrusion components 83, and the force-applying columns 86 are arranged on fixed brackets extending from the inside of the dipping table 2. The force-bearing columns 85 and the force-applying columns 86 perform periodic oscillation force application through electromagnetic action, and the frequency phases of the electrical signals introduced into all the force-applying columns 86 are the same after modulation.

[0041] like Figure 4 、 5 As shown, the force-applying column 86 can be an electromagnet. By inputting an electrical signal, it periodically generates suction and repulsion on the force-receiving column 85, driving the axial extrusion member 83 to perform a small periodic oscillation to produce an extrusion effect. Electrical signals are relatively easy to control the operating waveform, while mechanical oscillations are difficult to increase the frequency and control the frequency accuracy. Relatively speaking, the smaller the multiple of the ultrasonic frequency emitted by the ultrasonic port 53 and the oscillation frequency of the glue hydraulic pressure, the easier it is to generate resonance and promote glue impregnation. However, the frequency of hydraulic pressure change is limited by a large range of physical media and the inertia of the working components that drive the hydraulic pressure change, making it difficult to continuously increase. Therefore, it can only be selected based on a multiple relationship.

[0042] The hydraulic oscillating component 8 further includes a balancing spring 84 , one end of which abuts against the end of the axial extrusion member 83 . The preload force in the balancing spring 84 is equal to the pressure of the reference value of the pressure in the glue box 51 acting on the axial extrusion member 83 .

[0043] like Figure 5 As shown, the hydraulic reference value P multiplied by the end surface area of ​​the axial extrusion member 83 is equal to the preload force F1 of the balance spring 84. In this way, the suction force and repulsion force F2 between the force-bearing column 85 and the force-applying column 86 can oscillate at the zero-line reference value, and there is no need to perform waveform compensation and overall translation on the modulated electrical signal of the force-applying column 86, thereby reducing the control difficulty.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
