Description

Technical Field

[0002] In modern society, the widespread application of nuclear energy, including the operation of nuclear power plants, nuclear medicine diagnosis and treatment, scientific research and industrial application of radioactive materials, etc., makes people inevitably face the risk of nuclear radiation. In order to protect the health and safety of relevant personnel, personnel wear nuclear radiation protective clothing to work. Protective clothing builds an effective physical barrier between the human body and the radiation source to minimize the harm of radiation to the human body. Protective clothing is produced and processed through fabrics during production. The fabrics will go through a series of steps in the preparation process. Finally, the radiation protection coating is applied to the surface of the fabric through a coating machine. The coated fabric enters the dryer for drying and curing to become radiation protection fabric.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figure 1-Figure 10 The present invention provides a technical solution: a method for preparing nuclear radiation protective clothing fabric, comprising the following steps:

The coating glue with nuclear radiation protection function in this embodiment is the coating formula disclosed in the patent document CN104804640A;

[0048] S5, the conveyor belt 101 on the dryer is preheated by the preheating element below, so that the glue adhering to the surface of the conveyor belt 101 is heated and melted;

[0049] S6, scrubbing by a scrubbing component in the cleaning mechanism, and then drying by a drying component;

[0050] The drying machine in step S4 includes a machine body 100 and a conveyor belt 101 rotatably arranged on the machine body 100. The fabric is coated with an anti-nuclear radiation coating. The fabric is woven and then combined with a coating composite technology. It has excellent nuclear radiation shielding performance, good water washability, moisture permeability and breathability, lead-free, non-toxic, and non-sensitizing. The mechanical properties are better than similar shielding materials. Under the same shielding performance conditions, the unit gram weight is close to the level of similar foreign materials. It can be used for individual protection (such as protective clothing, protective hats, etc.) of nuclear power maintenance and maintenance personnel, radioactive operators, special environment monitoring, and radiation-related medical personnel. It can also be used for regional protection of individual areas such as protective tents, protective curtains, rolling doors, etc. A cleaning mechanism is provided at the bottom of the machine body 100, and the cleaning mechanism includes a scrubbing component and a drying component;

[0051] The scrubbing assembly includes a collection box 200 and a scrubbing rod 207 rotatably disposed on the collection box 200, two sets of second arc-shaped brushes 222 are disposed outside the scrubbing rod 207, two sets of first square tubes 209 are fixedly disposed on the collection box 200, and multiple sets of first spray tubes are evenly distributed on and along the length direction of the first square tube 209;

[0052] A long toothed ring 220 is fixedly sleeved on one end of the scrubbing rod 207, a short toothed ring 221 is rotatably arranged on the front of the collecting box 200, the long toothed ring 220 and the short toothed ring 221 are meshed, a driving motor 202 is fixedly arranged on the front of one end of the machine body 100, and a second transmission belt 206 is arranged between the working end of the driving motor 202 and the short toothed ring 221;

[0053] The collection box 200 is provided with a moving part for moving the scrubbing rod 207 back and forth. When the scrubbing rod 207 moves back and forth, the long toothed ring 220 is driven to move along with it. Since the long toothed ring 220 is relatively long, the long toothed ring 220 is always in meshing state with the short toothed ring 221 during the forward and backward movement. The moving part includes a raised ring 219 fixed on the front of the collection box 200 and a mounting bearing 218 fixed on the back of the collection box 200. A convex column 223 is fixedly provided on the back of the long toothed ring 220. The end of the convex column 223 can contact the raised ring 219. The collection box 200 collects the water from the upper part during the cleaning process and then discharges it outward through the discharge pipe on the front.

[0054] Two groups of T-shaped columns 217 are fixedly arranged on the back of the mounting bearing 218. The mounting bearing 218 consists of an inner ring, an outer ring and a ball. The inner ring is fixed on the back of the collecting box 200, and the outer ring is fixed together with the T-shaped column 217. A circular plate 216 is fixedly arranged on the other end of the brush rod 207. The end of the T-shaped column 217 passes through the inside of the circular plate 216. A plurality of groups of fixing springs 215 are fixedly arranged between the mounting bearing 218 and the circular plate 216. Branch pipes are fixedly arranged on the front sides of the two groups of first square tubes 209, and a connecting head is fixedly arranged on the front sides of the branch pipes.

[0055] Embodiment 2

[0056] Based on Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 The drying assembly includes a cleaning rod 208 rotatably arranged on the top of the collecting box 200 and two groups of mounting tubes 224. Two groups of first arc-shaped brushes 210 are arranged on the outside of the cleaning rod 208. The first arc-shaped brush 210 and the cleaning rod 208, and the second arc-shaped brush 222 and the scrubbing rod 207 are fixedly connected by two groups of bolts. The two groups of bolts are distributed at the two end positions of the second arc-shaped brush 222 and the first arc-shaped brush 210. The first arc-shaped brush 210 and the second arc-shaped brush 222 can be disassembled and replaced by the bolts when they are seriously worn. A plurality of groups of blowing heads are evenly distributed on the mounting tube 224 and along the length direction of the cleaning rod 208. A first transmission belt 205 is sleeved between the cleaning rod 208 and the scrubbing rod 207.

[0057] A lower hot air blower 203 is fixedly disposed on the back of the machine body 100, a pipeline 204 is fixedly disposed at the bottom of the lower hot air blower 203, and the end of the installation pipe 224 is connected to the pipeline 204;

[0058] The drying assembly also includes two groups of L-shaped rods 214 and scrapers 211 fixedly arranged on the top of the collection box 200. The two ends of the scrapers 211 are fixedly provided with I-shaped rods 212. The bottom of the I-shaped rod 212 passes through the inside of the L-shaped rod 214. The outside of the I-shaped rod 212 is sleeved with a mounting spring 213. When the scrapers 211 are used to scrape the water stains on the conveyor belt 101, the mounting spring 213 can make the I-shaped rod 212 generate a continuous upward force, thereby driving the scrapers 211 to generate a continuous upward force, so that the top of the scrapers 211 The degree of fit between the conveyor belt 101 is increased, and the scraper 211 is more effective in scraping off water stains on the surface of the conveyor belt 101. After the glue solidified on the surface of the conveyor belt 101 is cleaned by the cleaning mechanism, the upper surface of the conveyor belt 101 is dried by the installation tube 224 located above the conveyor belt 101 to reduce the residual water stains on the upper surface of the conveyor belt 101, that is, to increase the dryness of the inner wall surface of the conveyor belt 101, to avoid slipping and reduce friction when the inner wall of the conveyor belt 101 contacts the outer wall of the rotating shaft 106.

[0059] The cleaning mechanism of the present invention can timely clean the residual glue on the surface of the conveyor belt 101 during use, thereby preventing the solidified glue from contacting the fabric during the subsequent conveying process and causing contamination to the fabric of the nuclear radiation protective clothing. There is no need to stop the conveyor belt 101 to clean the surface of the conveyor belt 101. At the same time, the surface of the conveyor belt 101 can be kept clean, preventing the residual glue from causing friction in the fabric conveying and causing poor conveying, resulting in problems such as fabric wrinkles and deviations during the drying process, thereby ensuring the continuity and stability of the drying process and improving the drying efficiency of the glue on the fabric surface.

[0060] In summary, the connector on the branch pipe is connected to the external hot water supply device to transport high-pressure hot water to the inside of the first square tube 209, and at the same time, the lower hot air blower 203 is turned on. The lower hot air blower 203 transports hot air to the installation tube 224 through the pipeline 204, and then the drive motor 202 is turned on first. The working end of the drive motor 202 drives the short gear ring 221 to rotate through the second transmission belt 206, and the short gear ring 221 drives the long gear ring 220 to rotate, thereby driving the scrubbing rod 207 to rotate, and the scrubbing rod 207 drives the two external sets of second arc-shaped brushes 222 to rotate. When the scrubbing rod 207 rotates, the cleaning rod 208 is driven to rotate through the first transmission belt 205, and the cleaning rod 208 drives the two external sets of first arc-shaped brushes 210 to rotate. When the scrubbing rod 207 rotates, the rotating long gear ring 220 drives the protruding column 223 to rotate. The end of the protruding column 223 is a spherical structure, so the spherical part of the end of the protruding column 223 will contact the raised part of the raised ring 219 and move in the direction away from the raised ring 219, driving the long toothed ring 220, the brush rod 207, the second arc-shaped brush 222 and the circular plate 216 located on the brush rod 207 to move accordingly. At this time, the fixed spring 215 begins to stretch due to the movement of the circular plate 216. When the spherical part of the end of the protruding column 223 is separated from the raised part of the raised ring 219, the fixed spring 215 is reset, driving the circular plate 216, the brush rod 207 and other structures to return to their original positions, and so on, so that the rotating second arc-shaped brush 222 can move forward and backward in the process of cleaning the glue solidified on the surface of the upper conveyor belt 101, thereby increasing the cleaning effect of the second arc-shaped brush 222 on the solidified glue on the surface of the upper conveyor belt 101;

[0061] The coating glue with nuclear radiation protection function is evenly coated on the surface of the cloth-like fabric, and then the fabric coated with glue enters the conveyor belt 101 in the dryer, and the conveyor belt 101 rotates to the right to drive the fabric to move and transport. At this time, the hot air generated by the upper hot air blower 103 above is used to solidify and dry the glue on the surface of the fabric. During the conveying process, some glue will drip on the surface of the conveyor belt 101. At this time, the dripping and solidified glue moves with the conveyor belt 101 to the upper position of the collection box 200 below, and then first passes through the first square tube 209 on the far right. At this time, the multiple groups of first nozzles on the first square tube 209 on the far right spray hot water to the surface of the conveyor belt 101 to heat and rinse the solidified glue. Then, the rinsed solidified glue passes through the rotating second arc brush 222 and passes through the second arc brush 222. It is brushed, and the solidified glue after brushing is rinsed again by spraying hot water through multiple groups of first nozzles on the first square tube 209 located on the left side of the brushing rod 207, thereby increasing the effect of cleaning the solidified glue on the surface of the conveyor belt 101. Subsequently, the rinsed conveyor belt 101 passes over the rotating first arc-shaped brush 210, and the water stains on the surface of the conveyor belt 101 are swept away by the rotating first arc-shaped brush 210. Then the conveyor belt 101 passes the position of the scraper 211, and the water stains on the surface of the conveyor belt 101 are scraped away by the scraper 211, and then enters the position between the two groups of mounting tubes 224, and hot air is blown to the surface of the conveyor belt 101 through multiple groups of blowing heads on the mounting tubes 224, so as to accelerate the drying of the surface of the conveyor belt 101. At this time, when the conveyor belt 101 rotates to be located above the machine body 100, it can convey the fabric again.

[0062] Embodiment 3

[0063] Based on Example 2, please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 A preheating element is provided at the bottom of one end of the body 100, and the preheating element includes a long tube 300 and a fixed plate 301 arranged at the bottom of the long tube 300. The long tube 300 is connected to the pipeline 204. A heating plate 303 is fixedly provided on the surface of the fixed plate 301. The heating plate 303 can increase the temperature of heating and melting the solidified glue on the surface of the conveyor belt 101. A plurality of blowing nozzles 302 are fixedly provided on the surface of the long tube 300.

[0064] The present invention has a designed pre-heating component which, before scrubbing the glue adhered to the surface of the conveyor belt 101, blows hot air to the glue through the multiple groups of blowing nozzles 302 on the long tube 300, so as to preheat the solidified glue on the conveyor belt 101. At the same time, a higher temperature is generated by the heating plate 303 to heat the solidified glue to melt the glue, so that the second arc-shaped brush 222 can more effectively brush off the glue, thereby facilitating the subsequent scrubbing of the glue and improving the scrubbing effect of the solidified glue.

[0065] In summary, the hot air generated by the lower hot air blower 203 will also be transported to the long tube 300 through the pipeline 204. At this time, the solidified glue on the surface of the conveyor belt 101 is preheated through the multiple groups of blowing nozzles 302 on the long tube 300, so that the solidified glue on the surface of the conveyor belt 101 can be preheated and melted in advance. At the same time, a higher temperature is generated by the heating plate 303 to heat the solidified glue on the surface of the conveyor belt 101 again, so that the melting speed of the glue is accelerated.

[0066] An adjustment piece is provided between the fixed plate 301 and the long tube 300, and the adjustment piece includes an L-shaped plate 306 fixed at both ends of the fixed plate 301, and the interior of the L-shaped plate 306 is connected with a stud 305 through a thread, and the L-shaped plate 306 and the long tube 300 can be fixed together through the stud 305. Both ends of the long tube 300 are provided with multiple groups of sockets 304, and the working ends of the studs 305 are inserted into the interior of the sockets 304.

[0067] The present invention adopts a designed adjustment piece, which can adjust the distance between the heating plate 303 and the conveyor belt 101 according to the situation when the heating plate 303 heats and melts the solidified glue on the surface of the conveyor belt 101, thereby adjusting the melting temperature of the glue by the heating plate 303, ensuring that the pre-heating piece can accurately heat the glue on the surface of the conveyor belt 101 and improving the heating effect.

[0068] In summary, when the spacing between the heating plate 303 and the conveyor belt 101 is adjusted as needed, the stud 305 is first rotated in the direction away from the L-shaped plate 306, and then the working end of the stud 305 is disengaged from the inside of the socket 304, and then the fixed plate 301 is moved in the direction close to or away from the conveyor belt 101, driving the L-shaped plate 306 and the stud 305 to move with it, and then when it moves to the corresponding socket 304 position, it stops moving, and then the stud 305 is rotated in the direction close to the L-shaped plate 306, and then the working end of the stud 305 is screwed into the corresponding socket 304, and then the position of the fixed plate 301 and the heating plate 303 is adjusted, and the spacing between the heating plate 303 and the conveyor belt 101 is adjusted.

[0069] In this embodiment, a shell 102 is fixedly provided on the top of the body 100, and a plurality of upper hot air blowers 103 are fixedly provided on the shell 102. The upper hot air blowers 103 generate hot air to dry the glue on the fabric being conveyed. A connecting frame 201 is fixedly provided between the bottom of the body 100 and the collecting box 200.
