Description

Technical Field

[0001] The invention relates to the technical field of purge drying, in particular to a mesoporous felt purge drying device with a surface tension modification function. Background Art

[0002] Mesoporous felt is a mesoporous material (a three-dimensional mesh porous material prepared through a fiberization process) with a diameter of 2-50 nanometers. It has the following characteristics: a porosity of 70-95% and a specific surface area of ​​>200 m² / g; a concentrated pore size distribution (2-30 nanometers), and a surface rich in active groups such as hydroxyl groups; low mechanical strength (tensile strength <10 MPa), and is prone to pore collapse caused by capillary forces in the wet state. After wet molding (melt-gel method, electrospinning, etc.), the mesoporous felt requires drying to remove the solvent (water / organic solvent) to prevent cracking during subsequent high-temperature sintering; maintain the nanoscale pore structure to ensure catalytic and adsorption properties; and prevent the surface tension of residual liquid from destroying the mesoscopic ordered structure. The production of mesoporous felt mainly requires unwinding, mixing, impregnation, hot air curing, aging modification and drying stages. The aging modification and drying stages need to be carried out twice respectively. After drying, the micro-mesoporous felt can be rolled up; however, in the current drying process of mesoporous felt, evaporation drying is usually used, which makes the drying quality of the mesoporous felt poor and moisture may still remain in the mesopores. Summary of the Invention

[0003] The object of the present invention is to provide a mesoporous felt blowing and drying device with a surface tension modification function to solve the problems raised in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solutions: A mesoporous felt purging and drying device with a surface tension modification function includes a modification chamber, which is used to modify the mesoporous felt.

A plurality of inspection ports are provided on the surface of the body.

[0005] The modified mesoporous felt is transported into the machine body through the modification cavity, enters through the feed port, passes through the clean water component and the purge component in sequence, and is finally discharged through the discharge port and rolled up. In the process of the mesoporous felt passing through the clean water component, the clean water component squeezes and vibrates the mesoporous felt to remove the water in the mesopores, and then the mesoporous felt moves toward the purge component. When the mesoporous felt moves to the bottom of the purge component, the purge component purges the mesoporous felt to further dry the mesoporous felt.

[0006] Preferably, the water cleaning component consists of a water suction roller and two water pushing rollers, the two water pushing rollers are symmetrically arranged on the upper and lower sides of the water suction roller, a driving motor is provided at one end of the water suction roller, the driving shaft of the driving motor is connected to the water suction roller, a driving gear is provided on the driving shaft of the driving motor, and a driven gear is provided on the side of the water pushing roller close to the driving gear, and the driving gear is meshed with the driven gear.

[0007] Preferably, a suction pipe is provided at the center of the suction roller, and a plurality of water inlet grooves are provided on the wall of the suction pipe. One end of the water inlet groove is connected to the suction pipe, and the other end of the water inlet groove is connected to the inside of the machine body. A protrusion is symmetrically provided on one side of the water inlet groove away from the suction pipe.

[0008] Preferably, a blowing pipe is provided at the center of the water pushing roller, and a plurality of blowing grooves are provided on the wall of the blowing pipe, one end of the blowing groove is connected to the blowing pipe, and the other end of the blowing groove is connected to the interior of the machine body.

[0009] Preferably, the blowing slot corresponds to the water inlet slot one by one, and a push plate is symmetrically provided at one end of the blowing slot away from the blowing pipe. A tension spring is provided between the push plate and the water pushing roller. The push plate is a magnetic conductor, and an electromagnet is provided in the protrusion.

[0010] Preferably, the cross-section of the blowing slot at one end away from the blowing pipe is trapezoidal, and the spacing of the blowing slot close to the blowing pipe is greater than the spacing of the blowing slot close to the push plate.

[0011] Preferably, an air pump and an air extraction pump are provided inside the body, one end of the water suction pipe is connected to the air extraction pump through a pipe, and one end of the blowing pipe is connected to the air pump through a pipe. A filter chamber is also provided in the body, and the air extraction pump is connected to the filter chamber through a pipe.

[0012] The leading cloth of the mesoporous felt passes between the water-pushing roller and the water-absorbing roller. Since there are two water-pushing rollers, and the two water-pushing rollers are symmetrically arranged on the upper and lower sides of the water-absorbing roller, the mesoporous felt passes between the two sets of water-pushing rollers and the water-absorbing roller. Before the mesoporous felt enters, the controller controls the electromagnet in the protrusion to start; Then the controller controls the driving motor to start, and the driving shaft of the driving motor drives the driving gear and the water suction roller to rotate. Since the driving gear is engaged with the driven gear, the driving gear drives the driven gear to rotate when it rotates, so that the driven gear drives the water pushing roller to rotate, and then the water suction roller and the water pushing roller rotate at the same speed, ensuring that the blowing slot and the water inlet slot always maintain a one-to-one correspondence; and the controller controls the starting of the air pump and the air extraction pump. The air pump extracts the external gas and transports it to the blowing pipe through the pipeline, while the air extraction pump extracts the gas in the water suction pipe and transports it to the filter chamber through the pipeline for gas-liquid separation; After the water cleaning component is started, the mesoporous felt enters the machine body through the feed port and moves to the side close to the water absorption roller. When the mesoporous felt moves between the water pushing roller and the water absorption roller, the vertical line of the water inlet trough and the vertical line of the blowing trough are in a coincidence state, and the water inlet trough and the blowing trough are in a connected state. At this time, the distance between the protrusion and the push plate is the shortest, so the magnetic force generated by the electromagnet in the protrusion will attract the push plate. At this time, the attraction of the electromagnet to the push plate is greater than the pulling force of the spring on the push plate, so that the push plate moves along the side wall of the blowing trough to the side close to the water inlet trough. During the movement of the push plate, the mesoporous felt between the water pushing roller and the water absorption roller will be squeezed and pushed, so that the push plate drives the mesoporous felt to hit the water inlet trough; The push plate will vibrate when hitting the water inlet trough, and the vibration will be transmitted to the mesoporous felt, causing the liquid in the mesopores to fall out under the action of the vibration. In addition, the mesoporous felt between the water pushing roller and the water absorbing roller is squeezed by the push plate, and the diameter of its mesopores will change, causing the diameter of the mesopores to expand, thereby further increasing the amount of gas passing through the mesopores and promoting the efficiency of the liquid in the mesopores to separate from the mesopores, thereby improving the quality of the water purified by the mesoporous felt. At the same time, since the cross-section of the end of the blowing slot away from the blowing pipe is trapezoidal, and the spacing of the blowing slot close to the blowing pipe is larger than the spacing of the blowing slot close to the push plate, when the push plate moves toward the water inlet slot, the distance between the two push plates will be further reduced, and then the external gas is transported to the blowing slot through the blowing pipe and then transported from the blowing slot to the water inlet slot, the internal spacing of the blowing slot is gradually shortened, thereby accelerating the flow speed of the gas in the blowing slot, so that when it contacts the mesoporous felt, the impact force on the liquid in the mesopores is the greatest, further causing the liquid in the mesopores to separate from the mesoporous felt, and the electromagnet generates heat when it is energized, and the heat is transferred to the mesoporous felt through the water absorption roller, thereby completing the preheating treatment of the mesoporous felt; The liquid separated from the mesoporous felt will be mixed in the gas due to its nanometer diameter, and will be transported to the water suction pipe through the water inlet trough, and then transported to the filter chamber by the water suction pipe, and gas-liquid separation will be carried out in the filter chamber. Since the heat generated by the electromagnet will also act on the gas, the gas discharged from the water suction pipe will also carry heat, which is convenient for the subsequent drying of the mesoporous felt.

[0013] Preferably, the purge assembly consists of a drying chamber and several purge tubes, the purge tubes are installed in the drying chamber, the purge tubes consist of a cylindrical cavity and a honeycomb cavity, the diameter of the cylindrical cavity gradually decreases toward the side close to the honeycomb cavity, and an electric heating wire is provided in the purge tube.

[0014] Preferably, an impact tube and a plurality of spiral tubes are provided in the purge tube, the plurality of spiral tubes are arranged around the impact tube, and the impact tube and the spiral tubes are connected to the filter cavity through a pipeline.

[0015] Preferably, an auxiliary roller is provided between the clean water component and the purge component, and the auxiliary roller is used to transport the mesoporous felt.

[0016] The mesoporous felt treated with clean water moves toward the purge assembly under the action of several auxiliary rollers. When the mesoporous felt moves to the bottom of the drying chamber, the controller controls the electric heating wire in the purge tube to start, and opens the impact tube and the spiral tube, and then the gas separated by gas and liquid in the filter chamber is transported to the impact tube and the spiral tube through the pipeline. Since the axis of the impact tube is perpendicular to the mesoporous felt, when the impact tube blows toward the mesoporous felt, it directly impacts the mesoporous felt, and the spiral tube ejects a spiral airflow. The spiral airflow is outside the impact airflow and moves spirally around the impact airflow, and then the spiral airflow purges the surface of the mesoporous felt. In addition, the impact airflow impacts and dries the mesoporous felt, which further accelerates the drying efficiency of the mesoporous felt. In addition, since the heat generated by the electric heating wire in the purge tube is transferred to the gas, and the gas is subjected to the heat of the electromagnet in the water absorption pipe, the time required for heating the gas is shortened, thereby improving the efficiency of drying the mesoporous felt. Since the purge tube is composed of a cylindrical cavity and a honeycomb cavity, and the diameter of the cylindrical cavity gradually decreases toward the side close to the honeycomb cavity, the cross-section of the airflow is further shortened when it flows through the purge tube, thereby further increasing the flow rate of the airflow, and further increasing the impact of the airflow on the mesoporous felt. Therefore, when the high-temperature airflow flows to the mesopores, it can quickly transfer heat to the mesoporous felt, and remove moisture from the mesoporous felt as soon as possible, thereby improving the drying quality of the mesoporous felt.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The push plate will vibrate when it hits the water inlet trough, and the vibration will be transmitted to the mesoporous felt, causing the liquid in the mesopores to fall off under the action of the vibration. The mesoporous felt between the water pushing roller and the water absorbing roller is squeezed by the push plate, and the diameter of its mesopores will change, causing the diameter of the mesopores to expand, thereby further increasing the amount of gas passing through the mesopores and promoting the efficiency of the liquid in the mesopores to separate from the mesopores, thereby improving the quality of the water cleaned by the mesoporous felt.

[0018] 2. Since the cross-section of the blowing slot at one end away from the blowing pipe is trapezoidal, and the spacing of the blowing slot close to the blowing pipe is larger than the spacing of the blowing slot close to the push plate, when the push plate moves toward the water inlet slot, the distance between the two push plates will be further reduced. Then, after the external gas is transported to the blowing slot through the blowing pipe and then transported from the blowing slot to the water inlet slot, the internal spacing of the blowing slot is gradually shortened, thereby accelerating the flow rate of the gas in the blowing slot. When it contacts the mesoporous felt, the impact force on the liquid in the mesopores is the greatest, further causing the liquid in the mesopores to separate from the mesoporous felt. In addition, heat will be generated when the electromagnet is energized, and the heat will be transferred to the mesoporous felt through the water absorption roller, thereby completing the preheating treatment of the mesoporous felt.

[0019] 3. Since the axis of the impact tube is perpendicular to the mesoporous felt, when the impact tube blows towards the mesoporous felt, it directly impacts the mesoporous felt, while the spiral tube sprays out a spiral airflow. The spiral airflow is outside the impact airflow and moves spirally around the impact airflow, and then the spiral airflow blows the surface of the mesoporous felt. In addition, the impact airflow impact-dries the mesoporous felt, which further accelerates the drying efficiency of the mesoporous felt. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] As a specific embodiment of the present invention, the purge assembly 3 is composed of a drying chamber 31 and several purge pipes 32. The purge pipes 32 are installed in the drying chamber 31. The purge pipes 32 are composed of a cylindrical cavity 33 and a honeycomb cavity 34. The diameter of the cylindrical cavity 33 gradually decreases toward the side close to the honeycomb cavity 34. An electric heating wire is provided in the purge pipe 32.

[0031] As a specific embodiment of the present invention, an impact tube 35 and several spiral tubes 36 are provided in the purge tube 32. The several spiral tubes 36 are arranged around the impact tube 35. The impact tube 35 and the spiral tubes 36 are connected to the filter cavity through a pipeline.

[0032] Working principle of the present invention: The leading cloth of the mesoporous felt passes between the water-pushing roller 22 and the water-absorbing roller 21. Since there are two water-pushing rollers 22, and the two water-pushing rollers 22 are symmetrically arranged on the upper and lower sides of the water-absorbing roller 21, the mesoporous felt passes between the two sets of water-pushing rollers 22 and the water-absorbing roller 21. Before the mesoporous felt enters, the controller controls the electromagnet in the protrusion 214 to start; Then the controller controls the driving motor to start, and the driving shaft of the driving motor drives the driving gear 211 and the water suction roller 21 to rotate. Since the driving gear 211 is meshed with the driven gear 221, the driving gear 211 drives the driven gear 221 to rotate when it rotates, so that the driven gear 221 drives the water pushing roller 22 to rotate, and then the water suction roller 21 and the water pushing roller 22 rotate at the same speed, ensuring that the blowing slot 223 and the water inlet slot 213 always maintain a one-to-one correspondence; and the controller controls the air pump and the air extraction pump to start, the air pump extracts the external gas and transports it to the blowing pipe 222 through the pipeline, while the air extraction pump extracts the gas in the water suction pipe 212 and transports it to the filter chamber through the pipeline for gas-liquid separation; After the water cleaning component 2 is started, the mesoporous felt enters the machine body 1 through the feed inlet 11 and moves toward the side close to the water suction roller 21. When the mesoporous felt moves between the water pushing roller 22 and the water suction roller 21, the vertical line of the water inlet groove 213 and the vertical line of the blowing groove 223 are in a coincidence state, and the water inlet groove 213 and the blowing groove 223 are in a connected state. At this time, the protrusion 214 is closest to the push plate 224, so the magnetic force generated by the electromagnet in the protrusion 214 will attract the push plate 224. At this time, the attraction of the electromagnet to the push plate 224 is greater than the pulling force of the spring on the push plate 224, so that the push plate 224 moves along the side wall of the blowing groove 223 toward the side close to the water inlet groove 213. During the movement of the push plate 224, the mesoporous felt between the water pushing roller 22 and the water suction roller 21 is squeezed and pushed, so that the push plate 224 drives the mesoporous felt to hit the water inlet groove 213; The push plate 224 vibrates when striking the water inlet trough 213, and the vibration is transmitted to the mesoporous felt, causing the liquid in the mesopores to fall out under the action of the vibration. In addition, the mesoporous felt between the water pushing roller 22 and the water absorbing roller 21 is squeezed by the push plate 224, and the diameter of the mesopores changes, causing the diameter of the mesopores to expand, thereby further increasing the amount of gas passing through the mesopores and pushing the liquid in the mesopores to separate from the mesopores. At the same time, since the cross-section of the end of the blowing slot 223 away from the blowing pipe 222 is trapezoidal, and the spacing of the blowing slot 223 close to the blowing pipe 222 is greater than the spacing of the blowing slot 223 close to the push plate 224, when the push plate 224 moves toward the water inlet slot 213, the distance between the two push plates 224 will be further reduced, and then the external air is transported to the blowing slot 223 through the blowing pipe 222 and then transported to the water inlet slot 213 by the blowing slot 223. Since the internal spacing of the blowing slot 223 is gradually shortened, the flow speed of the gas in the blowing slot 223 is accelerated, so that when it contacts the mesoporous felt, the impact force on the liquid in the mesopores is the greatest, further causing the liquid in the mesopores to separate from the mesoporous felt, and the electromagnet generates heat when it is energized, and the heat is transferred to the mesoporous felt through the water absorption roller 21, thereby completing the preheating treatment of the mesoporous felt; The liquid separated from the mesoporous felt is mixed with the gas due to its nanometer-scale diameter. The liquid is transported to the water suction pipe 212 through the water inlet tank 213 and then transported to the filter chamber by the water suction pipe 212. The gas and liquid are separated in the filter chamber. Since the heat generated by the electromagnet also acts on the gas, the gas discharged from the water suction pipe 212 also carries heat, which facilitates the subsequent drying of the mesoporous felt. The mesoporous felt treated with clean water moves toward the purge assembly 3 under the action of several auxiliary rollers 13. When the mesoporous felt moves to the bottom of the drying chamber 31, the controller controls the electric heating wire in the purge pipe 32 to start, and opens the impact pipe 35 and the spiral pipe 36, so that the gas separated by gas and liquid in the filter chamber is transported to the impact pipe 35 and the spiral pipe 36 through the pipeline. Since the axis of the impact pipe 35 is perpendicular to the mesoporous felt, when the impact pipe 35 blows toward the mesoporous felt, it directly impacts the mesoporous felt, and the spiral pipe 36 ejects a spiral airflow. The spiral airflow is outside the impact airflow and moves spirally around the impact airflow, so that the spiral airflow purges the surface of the mesoporous felt, and the impact airflow impact-dries the mesoporous felt. In addition, since the heat generated by the electric heating wire in the purge tube 32 is transferred to the gas, and the gas is subjected to the heat of the electromagnet in the water absorption tube 212, the time required for heating the gas is shortened, thereby improving the efficiency of drying the mesoporous felt. In addition, since the purge tube 32 is composed of a cylindrical cavity 33 and a honeycomb cavity 34, and the diameter of the cylindrical cavity 33 gradually decreases toward the side close to the honeycomb cavity 34, the cross-section of the airflow is further shortened when it flows through the purge tube 32, thereby further increasing the flow rate of the airflow, and further increasing the impact of the airflow on the mesoporous felt. Therefore, when the high-temperature airflow flows toward the mesopores, it can quickly transfer heat to the mesoporous felt and remove moisture from the mesoporous felt as soon as possible.

[0033] 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.
