Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, and more specifically, it relates to an enamel reactor with a preheating function. Background Technique

[0002] An enamel reactor is a composite product in which glass containing high silica is lined on the inner surface of a steel container and firmly adhered to the metal surface after being calcined at high temperature. Therefore, it has the dual advantages of the stability of glass and the strength of metal, and is an excellent corrosion-resistant device. The enamel reaction is divided into two structures: open type and closed type. The open type has a separated body and cover, which are connected by gaskets and clamps in the middle, and generally has a volume of less than 5000L; the closed type has an integrated body and cover, and generally has a volume of more than 5000L. These two structures each have their own advantages. The open type is more convenient to disassemble. If there is a problem with the pipe orifice on the tank cover, it is easy to disassemble and repair it separately, while the closed type has better sealing performance. Generally speaking, the open type structure also has two types: butt-welded flange connection and flat cover type.

[0003] However, most of the existing enamel reactors lack a preheating function. When the materials just enter the reactor, the temperature is relatively low, the reaction is slow, which affects the processing efficiency of the enamel reactor. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide an enamel reactor with a preheating function.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an enamel reactor with a preheating function, including a reactor body and a preheating mechanism;

[0006] The preheating mechanism is arranged on the reactor body, and the preheating mechanism is used to preheat the materials entering the reactor body. The preheating mechanism includes a medium tank, a connecting pipe, a spiral pipe, a diversion assembly and a reflux assembly. The medium tank is sleeved on the reactor body, and the medium tank is fixedly connected to the reactor body. Both the upper and lower ends of the medium tank are communicated with a connecting pipe. A spiral pipe is arranged inside the medium tank. One end of the spiral pipe is communicated with the inside of the reactor body, and the other end of the spiral pipe penetrates through the side wall of the medium tank;

[0007] The diversion assembly is connected to the reactor body, and the diversion assembly is used to change the flow direction of the materials;

[0008] The reflux assembly is connected to the spiral pipe, and the reflux assembly is used to send the residual materials in the spiral pipe into the reactor body.

[0009] Preferably, the diversion assembly includes a diversion pipe, a three-way valve, and a direct current pipe. One end of the diversion pipe penetrates through the side wall of the medium tank and is connected to the spiral pipe. The end of the diversion pipe away from the spiral pipe is connected to one water outlet of the three-way valve. Another water outlet of the three-way valve is connected with a direct current pipe, and the end of the direct current pipe away from the three-way valve is connected to the kettle body.

[0010] Preferably, the reflux assembly includes a collection pipe, a collection tank, a water pump, and a reflux pipe. The collection pipe is connected to the lower end of the spiral pipe. One end of the collection pipe away from the spiral pipe is connected to a collection tank. A water pump is installed on the collection tank. The water inlet of the water pump is connected to the inside of the collection tank. The water outlet of the water pump is connected with a reflux pipe, and the end of the reflux pipe away from the water pump is connected to the kettle body.

[0011] Preferably, the reflux assembly further includes a solenoid valve, and the solenoid valve is installed on the collection pipe.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. Connect the lower end of the spiral pipe with the material. The material enters the kettle body through the upper end of the spiral pipe. When the material flows through the spiral pipe, the medium tank preheats the material in the spiral pipe, so that the material has a certain initial temperature when entering the kettle body, improving the reaction efficiency and further improving the processing efficiency of the enamel reaction kettle.

[0014] 2. When stopping injecting materials into the kettle body, some materials will remain in the spiral pipe. These remaining materials will enter the collection tank through the collection pipe. The water pump can pump the materials in the collection tank and pump them into the kettle body through the reflux pipe, thus avoiding the materials remaining in the spiral pipe.

[0023] Refer to Figure 1 and Figure 2 , the present invention provides a technical solution: an enamel reaction kettle with a preheating function, including a kettle body 1 and a preheating mechanism;

[0024] The preheating mechanism is arranged on the kettle body 1 and is used to preheat the materials entering the kettle body 1. The preheating mechanism includes a medium box 2, a connecting pipe 3, a spiral pipe 4, a diversion component and a reflux component. The medium box 2 is sleeved on the kettle body 1 and is fixedly connected to the kettle body 1. Connecting pipes 3 are communicated with both the upper and lower ends of the medium box 2. A spiral pipe 4 is arranged inside the medium box 2. One end of the spiral pipe 4 is communicated with the inside of the kettle body 1, and the other end of the spiral pipe 4 penetrates through the side wall of the medium box 2;

[0025] As Figure 2 , the medium box 2 is used to store a heat exchange medium, such as liquid or steam (selected according to the actual situation). The two connecting pipes 3 are respectively used for injecting or discharging the heat exchange medium;

[0026] The lower end of the spiral pipe 4 is communicated with the materials. The materials enter the kettle body 1 through the upper end of the spiral pipe 4. When the materials flow through the spiral pipe 4, the medium box 2 preheats the materials in the spiral pipe 4, so that the materials have a certain initial temperature when entering the kettle body 1, improving the reaction efficiency and further improving the processing efficiency of the enamel reactor;

[0027] The diversion component is connected to the kettle body 1 and is used to change the flow direction of the materials;

[0028] The reflux component is connected to the spiral pipe 4 and is used to send the residual materials in the spiral pipe 4 into the kettle body 1.

[0029] Specifically, the diversion component includes a diversion pipe 5, a three-way valve 6 and a direct current pipe 7. The diversion pipe 5 is communicated with the end of the spiral pipe 4 that penetrates through the side wall of the medium box 2. As Figure 2 , the diversion pipe 5 is communicated with the lower end of the spiral pipe 4. The end of the diversion pipe 5 away from the spiral pipe 4 is communicated with one water outlet of the three-way valve 6. Another water outlet of the three-way valve 6 is communicated with a direct current pipe 7. The three-way valve 6 can be pneumatic or electric (selected according to the actual situation). The end of the direct current pipe 7 away from the three-way valve 6 is communicated with the kettle body 1;

[0030] As Figure 2 , the water inlet of the three-way valve 6 is communicated with the material pipeline; when it is necessary to preheat the materials entering the kettle body 1, the material pipeline and the diversion pipe 5 are communicated through the three-way valve 6, and the materials enter the spiral pipe 4 for preheating; when it is not necessary to preheat the materials (for example, a small amount of auxiliary materials), the material pipeline and the direct current pipe 7 are communicated through the three-way valve 6, and the materials can directly enter the kettle body 1 through the direct current pipe 7, improving the filling efficiency.

[0031] Specifically, the reflux assembly includes a collecting pipe 8, a collecting box 9, a water pump 10 and a reflux pipe 11. The collecting pipe 8 is communicated with the lower end of the spiral pipe 4. One end of the collecting pipe 8 away from the spiral pipe 4 is communicated with a collecting box 9. A water pump 10 is installed on the collecting box 9. The water inlet of the water pump 10 is communicated with the inside of the collecting box 9. A reflux pipe 11 is communicated with the water outlet of the water pump 10. One end of the reflux pipe 11 away from the water pump 10 is communicated with the kettle body 1;

[0032] As Figure 2 , when the injection of materials into the kettle body 1 stops, some materials will remain in the spiral pipe 4. These remaining materials will enter the collecting box 9 through the collecting pipe 8. Then the water pump 10 can extract the materials in the collecting box 9 and pump them into the kettle body 1 through the reflux pipe 11, thereby preventing the materials from remaining in the spiral pipe 4.

[0033] Specifically, the reflux assembly further includes an electromagnetic valve 12. The electromagnetic valve 12 is installed on the collecting pipe 8 to control the on-off of the collecting pipe 8;

[0034] By blocking the collecting pipe 8 with the electromagnetic valve 12, the entry of materials into the collecting box 9 during normal preheating can be avoided; after the preheating is completed, the electromagnetic valve 12 is opened again.

[0035] Working principle: The lower end of the spiral pipe 4 is communicated with the materials. The materials enter the kettle body 1 through the upper end of the spiral pipe 4. When the materials flow through the spiral pipe 4, the medium box 2 preheats the materials in the spiral pipe 4, so that the materials have a certain initial temperature when entering the kettle body 1, improving the reaction efficiency and further enhancing the processing efficiency of the enamel reactor;

[0036] When the injection of materials into the kettle body 1 stops, some materials will remain in the spiral pipe 4. These remaining materials will enter the collecting box 9 through the collecting pipe 8. Then the water pump 10 can extract the materials in the collecting box 9 and pump them into the kettle body 1 through the reflux pipe 11, thereby preventing the materials from remaining in the spiral pipe 4.

[0037] It should be noted that: the electrical components appearing in this application document are all electrically connected to the external main controller and 220V mains power. And the main controller can be a processor, an alarm module, a drive module, etc., which play a role in controlling conventional known devices.

The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. in the existing technology for connection. And the machinery, parts and equipment all adopt conventional models in the existing technology. Coupled with the circuit connection adopting the conventional connection method in the existing technology, no specific description will be made here.
