DETAILED DESCRIPTION

[0023] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0024] Embodiment one

[0025] As Figure 1 And Figure 2 The utility model discloses a reaction kettle of preventing explosion, including reaction kettle outer cylinder 1, reaction kettle outer cylinder 1 outer surface lower part fixed connection has support frame 2, reaction kettle outer cylinder 1 upper end fixed connection has kettle cover 5, and the kettle cover 5 upper end middle part is installed with stirring mechanism 7, and reaction kettle outer cylinder 1 upper end outer circle ring array fixed connection has three pressure relief explosion -proof mechanism 6, and reaction kettle outer cylinder 1 upper end rear middle side fixed connection has liquid inlet 8, and kettle cover 5 lower end outer circle fixed connection has reaction kettle inner cylinder 9, and reaction kettle inner cylinder 9 outer surface lower part fixed connection has liquid outlet device 3, and reaction kettle outer cylinder 1 outer surface right -hand side upper side fixed connection has cooling explosion -proof mechanism 4.

[0026] The device is used for processing electroplating additives.

[0027] Before the device is implemented, clear water is injected into the cooling explosion -proof mechanism 4, so that the cooling explosion -proof mechanism 4 carries out cooling explosion -proof treatment to the reaction kettle inner cylinder 9.

[0028] The device is powered by plug-in power supply, which is a conventional operation in the prior art, and will not be described in detail herein.

[0029] Before the device is implemented, first:

[0030] The electroplating additive is first injected into the inner cylinder 9 of the reaction kettle through the opening of the liquid inlet 8, and then the liquid inlet 8 is closed after the injection is completed, so that the device has strong sealing performance during processing. After the liquid inlet 8 is closed, the stirring mechanism 7 is started to move, so that the stirring mechanism 7 stirs the electroplating additive in the inner cylinder 9 of the reaction kettle, improves the quality of the electroplating additive, and the stirring mechanism 7 can start the cooling and explosion-proof mechanism 4 to work when stirring the electroplating additive, so that the cooling and explosion-proof mechanism 4 cools the injected clean water, and then the cooled clean water is delivered to the gap between the outer cylinder 1 of the reaction kettle and the inner cylinder 9 of the reaction kettle, so that the cold water cools the inner cylinder 9 of the reaction kettle. Through the principle that hot water floats upward, the heat-exchanged water flows back into the cooling and explosion-proof mechanism 4, so that the cooling and explosion-proof mechanism 4 cools the heat-exchanged water again, and then delivers it to the gap between the outer cylinder 1 of the reaction kettle and the inner cylinder 9 of the reaction kettle, realizing water circulation cooling and explosion-proof treatment of the inner cylinder 9 of the reaction kettle.

[0031] In the above, if the pressure in the inner cylinder 9 of the reaction kettle is too high, the force of the pressure will act on the pressure relief and explosion-proof mechanism 6, so that the pressure relief and explosion-proof mechanism 6 is opened to release the pressure in the inner cylinder 9 of the reaction kettle. When the pressure in the inner cylinder 9 of the reaction kettle is equal to the external pressure, the pressure relief and explosion-proof mechanism 6 will automatically close to seal the inner cylinder 9 of the reaction kettle again, realizing pressure relief and explosion-proof treatment.

[0032] In the above, after the stirring mechanism 7 finishes processing the electroplating additive, the staff needs to place a collection barrel under the liquid outlet device 3, and then rotate to open the liquid outlet device 3, so that the processed electroplating additive flows into the collection barrel through the liquid outlet device 3 for collection.

[0033] In the above, the stirring mechanism 7 is composed of a stirring motor and a stirring rod, the stirring motor is fixedly connected to the middle part of the upper end of the kettle cover 5, the stirring rod is fixedly connected to the output end of the stirring motor, and the outer surface of the stirring rod is rotatably connected to the middle part of the kettle cover 5. After the electroplating additive is added, the output end of the stirring motor is started to rotate, the output end of the stirring motor drives the stirring rod to rotate through the coupling, so that the stirring rod stirs and processes the electroplating additive, improving the product quality.

[0034] In the above, the temperature sensor is fixedly connected to the upper part of the outer surface of the inner cylinder 9 of the reaction kettle. By setting the temperature value of the temperature sensor, when the temperature in the inner cylinder 9 of the reaction kettle is higher than the set value, a signal will be sent to the cooling and explosion-proof mechanism 4. At this time, the cooling and explosion-proof mechanism 4 will start to operate.

[0035] In the above, the temperature sensor can adopt an existing technology type I R80 infrared temperature sensor.

[0036] Example two

[0037] Further, in order to achieve the purpose of the pressure relief explosion-proof mechanism 6 when the pressure in the inner cylinder 9 of the reaction kettle is too high, the pressure force pushes the pressure relief explosion-proof mechanism 6 to open, so that the pressure relief explosion-proof mechanism 6 can release pressure, refer to Figure 3 The pressure relief explosion-proof mechanism 6 includes a pressure relief cylinder 61 fixedly connected to the upper end of the outer cylinder 1 of the reaction kettle, a limiting rod 63 slidably connected to the middle of the upper end of the pressure relief cylinder 61, a sealing valve 62 fixedly connected to the lower end of the limiting rod 63, a rebound spring 64 fixedly connected between the upper end of the sealing valve 62 and the top wall of the pressure relief cylinder 61, and a plurality of gas outlets 65 arranged in an annular array on the upper part of the outer surface of the pressure relief cylinder 61.

[0038] Further, the sealing valve 62 is slidably connected to the inner cavity of the pressure relief cylinder 61, and the pressure relief cylinder 61 is in communication with the inner cylinder 9 of the reaction kettle.

[0039] In the above, when the pressure in the inner cylinder 9 of the reaction kettle is higher than the external pressure plus the pressure of the rebound spring 64, the pressure force will push the sealing valve 62 to slide upward in the inner cavity of the pressure relief cylinder 61. When the sealing valve 62 moves upward, it will drive the limiting rod 63 to slide at the upper end of the pressure relief cylinder 61, increasing the stability of the sealing valve 62 when it slides. When the lower end of the sealing valve 62 slides to the upper part of the gas outlet 65, the pressure in the inner cylinder 9 of the reaction kettle will be released from the gas outlet 65, achieving the effect of pressure relief explosion-proof in the inner cylinder 9 of the reaction kettle.

[0040] In the above, when the sealing valve 62 slides upward, it will squeeze the rebound spring 64 to generate pressure. When the pressure in the inner cylinder 9 of the reaction kettle is released, when the pressure is equal to the external pressure, the rebound spring 64 will release the pressure, pushing the sealing valve 62 to slide downward, so that the sealing valve 62 slides to the lower part of the gas outlet 65, making the sealing valve 62 close the pressure relief cylinder 61 and the inner cylinder 9 of the reaction kettle, so that the inner cylinder 9 of the reaction kettle returns to the sealed state.

[0041] Further, in order to achieve the purpose of the cooling explosion-proof mechanism 4 for circulating cooling explosion-proof of the inner cylinder 9 of the reaction kettle, refer to Figure 4 The cooling explosion-proof mechanism 4 includes a fixed plate 44 fixedly connected to the right upper side of the outer surface of the outer cylinder 1 of the reaction kettle, a heat exchange box 41 fixedly connected to the left middle side of the upper end of the fixed plate 44, a water pump 42 fixedly connected to the right middle side of the upper end of the fixed plate 44, the input end of the water pump 42 being fixedly connected to the heat exchange box 41, the output end of the water pump 42 being fixedly connected to a water delivery pipe 43, and a water inlet valve 45 fixedly connected to the rear right side of the upper end of the heat exchange box 41.

[0042] Further, the input end of the heat exchange box 41 is in communication with the right upper side of the outer surface of the outer cylinder 1 of the reaction kettle, and the water outlet of the water delivery pipe 43 is in communication with the right lower side of the outer surface of the outer cylinder 1 of the reaction kettle.

[0043] In the above, the water inlet valve 45 is used to inject clean water into the heat exchange box 41, so that the heat exchange box 41 can store and cool.

[0044] When the stirring mechanism 7 stirs the electroplating additives, the water pump 42 is started to move, so that the water pump 42 delivers the water cooled by the heat exchange box 41 into the water delivery pipe 43, and then the cooled water is delivered into the gap between the reactor outer cylinder 1 and the reactor inner cylinder 9 through the water delivery pipe 43, so that the cold water exchanges heat with the reactor inner cylinder 9, reduces the temperature of the reactor inner cylinder 9, and achieves the purpose of explosion prevention by cooling.

[0045] When water is continuously injected between the reactor outer cylinder 1 and the reactor inner cylinder 9, the water level will rise, and the water with higher temperature will float to the upper part through the principle of hot water floating upward, and then flow into the heat exchange box 41 through the input end of the heat exchange box 41, so that the heat exchange box 41 cools the water after heat exchange, and then the water pump 42 sucks the cooled water into the inside through the input end, and then delivers the cooled water into the water delivery pipe 43 through the output end, so that the water delivery pipe 43 delivers the cooled water into the gap between the reactor outer cylinder 1 and the reactor inner cylinder 9, and realizes the purpose of circulating cooling.

[0046] The heat exchange box 41 uses water as a cooling medium, and is a device for realizing heat exchange between fluids with different temperatures, which can adopt a model LX-150 cooling water circulating machine in the prior art.

[0047] Further, in order to realize the rotating liquid outlet device 3, the liquid outlet device 3 is opened to release the electroplating additives in the reactor inner cylinder 9, and refer to Figure 5 The liquid outlet device 3 includes a liquid outlet cylinder 31 fixedly connected to the lower part of the outer surface of the reactor inner cylinder 9, a threaded rod 35 threadedly connected to the middle part of the lower end of the liquid outlet cylinder 31, a flange plate 36 fixedly connected to the lower end of the threaded rod 35, a piston rod 33 rotatably connected to the upper end of the threaded rod 35, a sealing ring 34 fixedly connected to the upper part and the lower part of the outer surface of the piston rod 33, a liquid outlet 32 annularly arranged on the middle part of the outer surface of the liquid outlet cylinder 31, and a leakage disc 37 fixedly connected to the lower part of the outer surface of the liquid outlet cylinder 31.

[0048] Further, the upper part of the outer surface of the liquid outlet cylinder 31 is fixedly connected to the lower part of the outer surface of the reactor outer cylinder 1, the piston rod 33 is slidingly connected to the inner cavity of the liquid outlet cylinder 31, and the liquid outlet cylinder 31 is in communication with the reactor inner cylinder 9.

[0049] In the above, when the liquid outlet device 3 is opened, a collection barrel needs to be placed under the liquid outlet device 3.

[0050] In the above, the flange plate 36 drives the threaded rod 35 to rotate by rotating the flange plate 36, when the threaded rod 35 rotates, the threaded rod 35 moves downward by the threaded connection with the liquid outlet cylinder 31, when the liquid outlet cylinder 31 moves downward, the piston rod 33 moves downward together, the sealing of the piston rod 33 to the reaction kettle outer cylinder 1 is released, the electroplating additives flow into the liquid outlet cylinder 31, when the upper end position of the piston rod 33 moves to the lower part of the liquid outlet 32, the electroplating additives flow out of the liquid outlet cylinder 31 through the liquid outlet 32, and then flow into the leakage disc (37), the leakage disc (37) is designed to be inclined, so that the electroplating additives flow uniformly to the opening direction of the leakage disc (37), and the electroplating additives flow into the collection barrel for collection.

[0051] In the above, the leakage disc (37) is protected by the shell, so that the electroplating additives cannot be sprayed from the outside of the liquid outlet 32, the flow direction of the electroplating additives is limited by the shell, and the electroplating additives cannot drop on the arms of the workers when the workers rotate the flange plate 36, so that the safety of the workers is ensured.

[0052] In the above, the sealing ring 34 is used to ensure the sealing between the piston rod 33 and the liquid outlet cylinder 31, so that the liquid cannot flow to the lower part of the piston rod 33.

[0053] It should be particularly pointed out that the specific installation mode of the heat exchange box 41 and the water pump 42 and the connection mode of the circuit and the control method all belong to conventional design, and the utility model will not be described in detail.
