Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof and pressure-relieving technology, in particular to an explosion-proof and pressure-relieving device for producing hydrophobic glass coating liquid. Background Art

[0002] The explosion-proof pressure relief device is a device that releases excessive pressure inside the preparation device during the production of hydrophobic glass coating liquid. When using the explosion-proof pressure relief device, when the internal pressure of the preparation tank for producing hydrophobic glass coating liquid is too high, the operator rotates the turntable, which in turn drives the threaded rod to rotate, thereby moving the block away from the inside of the pressure relief valve. This can release part of the gas inside the preparation tank, thereby preventing the pressure inside the preparation tank from decreasing to a certain extent, thereby preventing the preparation tank from exploding due to excessive pressure.

[0003] The inventors found in their daily work that the explosion-proof pressure relief device still has at least the following problems: when using the explosion-proof pressure relief device, when the internal pressure of the preparation tank for producing hydrophobic glass coating liquid is too high, the operator rotates the turntable, which in turn drives the threaded rod to rotate, thereby moving the block away from the inside of the pressure relief valve. This can release part of the gas inside the preparation tank, which to a certain extent prevents the pressure inside the preparation tank from decreasing, and thus prevents the preparation tank from exploding due to excessive pressure. However, in actual use, during long-term use, the block will have a certain degree of wear, because most pressure relief valves are integrated, which makes the block more difficult to replace.

The inner wall of the positioning groove 802 is provided with a rubber cone sleeve 803. The inner wall of the rubber cone sleeve 803 is fixedly connected to the surface of the connecting pipe 2. When using the connecting device 8, the fixing sleeve 801 is manually sleeved on the end of the connecting pipe 2 away from the main body 1 of the pressure relief device, and then the rubber cone sleeve 803 is squeezed into the positioning groove 8 02, so that the fixing sleeve 801 can be well restricted to the surface of the connecting pipe 2. The reverse operation can facilitate the separation of the fixing sleeve 801 and the connecting pipe 2, thereby facilitating the replacement of the stopper 6. A limiting groove 805 is provided on the surface of the connecting pipe 2. The inner wall of the limiting groove 805 is provided with a second rubber ring 806. The end of the second rubber ring 806 away from the limiting groove 805 is fixedly connected to the inner wall of the fixing sleeve 801.

The surface of the fixing sleeve 801 is fixedly connected to the connecting ring 807, and the surface of the connecting ring 807 is sleeved with a supporting sleeve 808. The side of the connecting ring 807 close to the fixing sleeve 801 is evenly fixedly connected with a fixing rod 809, and the fixing rod 809 slides through and is inserted into the support sleeve 80 8, the fixing rod 809 passes through the support sleeve 808, which can effectively prevent the support sleeve 808 from rotating on the side of the connecting ring 807. A first bolt 810 is inserted through a uniform thread on one side of the support sleeve 808. The first bolt 810 is fixedly connected to a rubber block 811 at one end close to the connecting pipe 2. The rubber block 811 is arranged inside the fixing groove 812. The first bolt 810 is manually controlled to rotate, so that the rubber block 811 is squeezed into the inside of the fixing groove 812, which can effectively fix the support sleeve 808 on one side of the connecting ring 807.

[0029] Reference Figure 3 and Figure 4The protective device 9 includes a conical sleeve 901, and the top of the air outlet 4 is evenly fixedly connected with a round rod 902. The top of the round rod 902 and the bottom of the conical sleeve 901 are fixedly connected. The conical sleeve 901 is arranged on the top of the air outlet 4. When the protective device 9 is used, the conical sleeve 901 is restricted to the top of the air outlet 4 by the round rod 902. This can prevent the liquid from being splashed out to a certain extent. A circular groove 903 is provided on the surface of the air outlet 4. The inner wall of the circular groove 903 is slidably connected with a first connecting sleeve 904 and a second connecting sleeve 905. A positioning groove 906 is provided on one side of the second connecting sleeve 905. A positioning block 907 is slidably connected to the inner wall of the positioning groove 906. The positioning block 907 is fixedly connected to one side of the first connecting sleeve 904 at one end away from the positioning groove 906. The first connecting sleeve 904 and the second connecting sleeve 905 are sleeved inside the circular groove 903, and then the positioning block 907 is slid into the positioning groove 906, so that the first connecting sleeve 904 and the second connecting sleeve 905 can be well set at the bottom of the conical sleeve 901, so that the liquid brought out by the pressure relief can be collected into the first connecting sleeve 904 and the second connecting sleeve 905. A water outlet hole 910 is provided at the bottom of the inner wall of the second connecting sleeve 905, and a rubber plug 911 is provided on the inner wall of the water outlet hole 910.

[0030] Working principle: when using the explosion-proof pressure relief device, when the internal pressure of the preparation tank for preparing the hydrophobic glass coating liquid is too high, the operator rotates the turntable 5, which drives the threaded rod 7 to rotate, so that the stopper 6 is away from the inside of the pressure relief valve, so that part of the gas inside the preparation tank can be released, which can prevent the pressure inside the preparation tank from becoming smaller to a certain extent, so that the surface preparation tank will explode due to excessive pressure. When using the connecting device 8, the fixing sleeve 801 is manually sleeved on the end of the connecting pipe 2 away from the pressure relief device body 1, and then the rubber conical sleeve 803 is squeezed into the inside of the positioning groove 802, and then the second rubber ring 806 is squeezed into the inside of the limiting groove 805, so that the end of the connecting pipe 2 away from the pressure relief device body 1 is squeezed on the side of the first rubber ring 804, which can play a good sealing role and prevent liquid leakage. In this way, the fixing sleeve 801 can be well restricted to the surface of the connecting pipe 2, and then the fixing rod 809 is passed through the support sleeve 808, which can well prevent the support sleeve 808 from being stuck in the connecting ring 807. One side is rotated, and the first bolt 810 is manually controlled to rotate, so that the rubber block 811 is squeezed into the inside of the fixing groove 812, so that the support sleeve 808 can be well fixed to one side of the connecting ring 807. The reverse operation can facilitate the separation of the fixing sleeve 801 and the connecting pipe 2, which is convenient for replacing the stopper 6. When using the protective device 9, the conical sleeve 901 is restricted to the top of the air outlet 4 by the round rod 902, which can prevent the liquid from being splashed out to a certain extent, and the first connecting sleeve 904 and the second connecting sleeve 905 are sleeved inside the circular groove 903, and then the positioning block 907 is slid into the inside of the positioning groove 906, so that the first connecting sleeve 904 and the second connecting sleeve 905 can be well set at the bottom of the conical sleeve 901, and the second bolt 908 is manually controlled to rotate, and then the second bolt 908 is threadedly inserted into the inside of the thread groove 909, so as to fix the first connecting sleeve 904 and the second connecting sleeve 905 together, so that the liquid brought out by the pressure relief can be collected into the inside of the first connecting sleeve 904 and the second connecting sleeve 905.
