[0031] Example 1

[0032] This embodiment is a large-capacity metering and mixing tank for producing thermoplastic phenolic resin. The raw materials such as formaldehyde and phenol used in the production of thermoplastic phenolic resin are measured and preliminarily mixed in the tank. According to the different amounts of formaldehyde, phenol and methanol used, a special metering method is adopted to achieve the purpose of measuring and mixing more production raw materials at one time in the tank body.

[0033] The metering mixing tank of this embodiment includes a tank body. The height of the tank body is increased to accommodate more substances such as formaldehyde and phenol. From the overall structure of the tank body, the outer periphery of the tank body of this embodiment has an insulation layer, and an insulation shell 2 is installed on the outer periphery of the insulation layer. An interlayer is provided between the insulation layer and the shell of the tank body. A condenser is installed on the outer periphery of the tank body. The condenser is connected to the interlayer through a pipeline to cool the tank body, so that the gaseous raw materials in the upper layer can be better transformed into liquid, which facilitates the transportation of the tank body materials.

[0034] Since the height of the tank body of this embodiment is increased, for example, the tank body of this embodiment spans 2 and 3 floors. Therefore, this embodiment is provided with a support platform 1 on the outer periphery of the tank body. The support platform 1 of this embodiment is a steel pedal laid on a steel platform. As a reinforcement structure, a through hole is opened on the support platform 1 and penetrates the support platform 1. The tank body is passed through the through hole. The support platform 1 is arranged in the upper half of the tank body. A reinforcement frame 14 is installed at the lower end of the support platform 1. The reinforcement frame 14 is made of square steel pipe. The upper end of the reinforcement frame 14 is fixedly connected to the support platform 1. The reinforcement frame 14 is arranged on the outer periphery of the tank body and is surrounded by 8 square steel pipes to form a regular octagonal reinforcement frame 14.

[0035] The height of the tank body of this embodiment is increased and the capacity is increased. Therefore, this embodiment uses a weighing module 13 to weigh the material entering the tank body and then measure it. Specifically, a support seat 3 is installed on the tank body, and the support seat 3 is welded to the tank body. There are three support seats 3 on the tank body, and the support seats 3 are evenly arranged around the central axis of the tank body. The weighing module 13 is installed on the upper end of the support platform 1, and the lower end of the support seat 3 is connected to the weighing module 13. In addition, a reinforcement frame 14 is located below the weighing module 13, and multiple reinforcement frames 14 are connected into a whole using square steel pipes or I-beams.

[0036] A protective convex plate 11 is welded to the upper end of the support platform 1 of this embodiment. The protective convex plate 11 is arranged on the outer periphery of the weighing module 13. The height of the protective convex plate 11 is not less than one-half of the height of the weighing module 13. For example, the height of the protective convex plate 11 in this embodiment is two-thirds of the height of the weighing module 13. This embodiment uses the protective convex plate 11 to surround the weighing module 13, so that the tank body, the weighing module 13 and the support platform 1 where people walk are separated, thereby preventing debris from entering the weighing module 13.

[0037] This embodiment has multiple feed pipes and discharge pipes 12. Specifically, an exhaust gas delivery pipe 6, a phenol delivery pipe 4, a formaldehyde delivery pipe 5 and a methanol delivery pipe 8 are installed at the upper end of the tank body, wherein the exhaust gas delivery pipe 6 is arranged at the center of the upper end of the tank body. The exhaust gas generated in the tank rises and reaches the purification equipment along the exhaust gas delivery pipe 6. The phenol delivery pipe 4, the formaldehyde delivery pipe 5 and the methanol delivery pipe 8 are feed pipes, wherein the phenol delivery pipe 4, the formaldehyde delivery pipe 5 and the methanol delivery pipe 8 are arranged on the outside of the exhaust gas delivery pipe 6. The inner diameters of the phenol delivery pipe 4 and the formaldehyde delivery pipe 5 are both larger than the inner diameter of the methanol delivery pipe 8. The inner diameters of the phenol delivery pipe 4 and the formaldehyde delivery pipe 5 are the same. A flow meter is installed on the methanol delivery pipe 8, and a protective shell is installed on the periphery of the flow meter. In this embodiment, the amount of phenol and formaldehyde is measured by a weighing module 13, and the amount of methanol is measured by a flow meter.

[0038] In this embodiment, a steam delivery pipe 7 is installed on the tank body, and the outer periphery of the steam delivery pipe 7 is covered with an insulation layer. The outlet of the steam delivery pipe 7 is arranged at the discharge port pipe at the lower end of the tank body. Specifically, a sleeve is installed on the outer periphery of the discharge port pipe, and the sleeve and the discharge port pipe form a heating cavity. The outlet of the steam delivery pipe 7 is connected with the heating cavity, and the steam delivered by the steam delivery pipe 7 enters the heating cavity to heat the discharge port pipe, thereby allowing the preliminarily mixed material to flow out of the discharge port pipe smoothly, avoiding the discharge port pipe from being blocked due to low material temperature. In addition, this embodiment can also preheat the material. In this embodiment, the interlayer can be divided into two parts, the lower end interlayer and the non-lower end interlayer, by using a partition. The steam delivery pipe 7 is connected to the lower end interlayer at the lower end of the tank body, and steam is used to preheat the material to be introduced into the discharge port pipe.

[0039] In this embodiment, a metal hose 10 is installed on the tail gas delivery pipe 6, the phenol delivery pipe 4, and the formaldehyde delivery pipe 5, and a metal hose 10 is installed on the discharge pipe 12. In addition, in this embodiment, a detection tube is installed on the tank body, and a combustible gas detection sensor and a toxic gas detection sensor are installed on the detection tube.

[0040] As a structure for maintenance and observation, an inclined cylinder is installed on the shell of the tank body, and a sealing cover 9 is installed on the cylinder body.

[0041] In this embodiment, formaldehyde and phenol are measured in the tank body, and the methanol flowing through the methanol delivery pipe 8 is measured by a flow meter. The discharge port pipe is heated by steam to prevent the discharge port pipe from being blocked by the material and to prevent the mixed material in the tank body from blocking the discharge port pipe.

[0042] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.

[0043] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it does not limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or variations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
