Specific implementation manners
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-5As shown in the figure, a protective device includes a glass reaction kettle 1. Symmetrically arranged around the glass reaction kettle 1 are not less than two arc-shaped plates 2. A plurality of arc-shaped plates 2 are circumferentially distributed along the outer side of the glass reaction kettle 1. During actual use, the arc-shaped plates 2 can be made of stainless steel material. Stainless steel is not easy to rust, has good corrosion resistance, and can resist the erosion of most chemical media, including acids, alkalis, salts, etc.; it also includes: a buffer component 9 arranged on the inner wall of the arc-shaped plate 2 for protecting the glass reaction kettle 1 from the outside. By setting the buffer component 9, it can effectively prevent the direct impact of external objects on the glass reaction kettle 1, avoid the rupture or damage of the glass reaction kettle 1 caused by external forces, and thus protect the chemical reaction inside the glass reaction kettle 1 from being disturbed; both ends of each arc-shaped plate 2 are fixedly connected with a strip-shaped plate 3. A plurality of limit holes 4 are opened on one side of the strip-shaped plate 3. A threaded rod 5 is arranged between adjacent limit holes 4; an opposing tension component 6 arranged at one end of the threaded rod 5 for strengthening the clamping stability of the arc-shaped plate 2. By setting the opposing tension component 6, it is convenient to quickly assemble a plurality of arc-shaped plates 2, so that a plurality of arc-shaped plates 2 can protect the glass reaction kettle 1 from the outside; the other end of the threaded rod 5 is provided with a fastening component 7 for improving the assembly speed of the arc-shaped plate 2. By setting the fastening component 7 and cooperating with the opposing tension component 6, the gap or looseness between the arc-shaped plate 2 and the glass reaction kettle 1 can be eliminated, making the connection between the arc-shaped plate 2 and the glass reaction kettle 1 more tightly stable, and further improving the protection performance; a strengthening component 8 is arranged between the strip-shaped plates 3 for enhancing the overall strength of the arc-shaped plate 2.
[0024] The buffer component 9 includes a heat insulation layer 93 fixed to the inner wall of the arc-shaped plate 2. The heat insulation layer 93 is made of glass fiber cotton material. One side of the heat insulation layer 93 is fixedly connected with a protective soft pad 92. The protective soft pad 92 is designed in a wavy shape. One side of the protective soft pad 92 is fixedly connected with a heat preservation layer 91. The heat preservation layer 91 is made of polyurethane foam material. As Figure 3 shown, by setting the heat preservation layer 91, the heat of the glass reaction kettle 1 is less likely to escape, which is beneficial to keeping the temperature inside the glass reaction kettle 1 balanced. Then, by using the protective soft pad 92, the hard contact between the arc-shaped plate 2 and the glass reaction kettle 1 can be changed into the flexible contact between the protective soft pad 92 and the glass reaction kettle 1, so that the glass reaction kettle 1 evenly releases pressure to one side of the arc-shaped plate 2, thus improving the protection performance. By setting the heat insulation layer 93, the heat exchange rate between the glass reaction kettle 1 and the outside can be slowed down, and the staff can be prevented from being scalded due to the excessive temperature of the arc-shaped plate 2 after absorbing heat.
[0025] A plurality of installation holes 10 are opened inside the protective soft pad 92. The installation holes 10 are designed in a spindle shape. A buffer strip 11 is installed inside each installation hole 10. The buffer strip 11 is made of rubber or silica gel material. As Figure 3 shown, by setting the buffer strip 11, the spindle shape design can balance the strength and weight of the overall structure of the protective soft pad 92 to optimize its support performance.
[0026] The tensioning assembly 6 includes a fixing cylinder 61 fixed to one side of the strip plate 3. A yielding cavity 62 is provided inside the fixing cylinder 61. One end of the threaded rod 5 penetrates into the yielding cavity 62 and is fixedly connected with a conical block 64. A plurality of tensioning pieces 63 are symmetrically arranged outside the conical block 64. One end of the tensioning piece 63 is connected to the strip plate 3, and the inner wall of the tensioning piece 63 is in contact with the conical block 64. As Figure 2 、 Figure 4 shown, the threaded rod 5 will drive the conical block 64 at one end thereof to penetrate deep into the yielding cavity 62, and the conical block 64 will force a plurality of tensioning pieces 63 outside it to gradually expand outwards. Under the elastic potential energy of the tensioning pieces 63, the arc-shaped plates 2 will be tightened with each other to generate a pre-tightening force, so as to improve the clamping stability of the glass reactor 1, and the plurality of arc-shaped plates 2 will protect it from the outside of the glass reactor 1.
[0027] A docking groove 12 is formed on the inner wall of each tensioning piece 63. A docking block 13 is slidably connected inside the docking groove 12. One side of the docking block 13 is connected to the conical block 64. As Figure 4 shown, by providing the docking groove 12 and the docking block 13, on the one hand, the conical block 64 can move smoothly during the process of penetrating into the yielding cavity 62, improving the stability of the structure. On the other hand, the rotation of the threaded rod 5 can be restricted to prevent the threaded rod 5 from loosening and reducing the clamping stability of the arc-shaped plate 2.
[0028] The fastening assembly 7 includes a spring washer 72 arranged at one end of the threaded rod 5. A lock nut 71 is provided on the side of the spring washer 72 away from the strip plate 3. The lock nut 71 is threadedly connected to the threaded rod 5. The spring washer 72 is in contact with both the lock nut 71 and the strip plate 3. As Figure 3 shown, by providing the spring washer 72, the loosening of the lock nut 71 caused by vibration, movement, etc. can be effectively prevented. When installing the lock nut 71, an external force is applied to generate an elastic reaction force, thereby preventing the lock nut 71 from loosening.
[0029] The strengthening assembly 8 includes a support plate 81 arranged between the strip plates 3. There are two support plates 81 arranged in parallel. The support plate 81 is fixedly installed on the arc-shaped plate 2. A plurality of reinforcing ribs 82 are provided on the outside of the arc-shaped plate 2. The reinforcing ribs 82 are respectively connected to the two end support plates 81. As Figure 5 shown, through the reinforcing ribs 82 between the support plates 81, the anti-bending performance of the arc-shaped plate 2 can be improved, thereby enhancing the overall strength of the arc-shaped plate 2, prolonging the service life of the arc-shaped plate 2, and having better explosion-proof performance for the glass reactor 1.
[0030] Working principle: First, the staff can make the adjacent arc-shaped plates 2 be tightened against each other to generate a pre-tightening force through the pulling assembly 6 in cooperation with the fastening assembly 7, so as to eliminate the gap or looseness between the arc-shaped plate 2 and the glass reactor 1, make the connection between the arc-shaped plate 2 and the glass reactor 1 more tightly stable, improve the clamping stability of the glass reactor 1. Then, on the one hand, the buffer assembly 9 is beneficial to keeping the temperature in the glass reactor 1 balanced, slowing down the heat exchange rate between the glass reactor 1 and the outside, and avoiding scalding the staff due to the over-high temperature of the arc-shaped plate 2 after absorbing heat. On the other hand, it changes the hard contact into the flexible contact between the protective soft pad 92 and the glass reactor 1, so that the glass reactor 1 evenly releases pressure towards the arc-shaped plate 2 side, further improving the protection performance. At the same time, the overall strength of the arc-shaped plate 2 can be improved through the strengthening assembly 8, making the arc-shaped plate 2 more durable and having better explosion-proof performance.
