Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for preparing phenolic resin materials. Background Technology

[0002] A phenolic resin reactor is a closed container device specifically used for the synthesis and reaction of phenolic resins. It is used to react phenols and aldehydes under controlled temperature and pressure conditions to form the raw material for phenolic resins. After the phenolic resin is synthesized in the reactor, it is usually used as the base for liquid prepolymers or adhesive products. During the curing process of phenolic resin materials, the ratio of phenolic resin during synthesis directly affects the curing speed of the phenolic resin materials.

[0003] Conventional phenolic resin material preparation reactors typically use a vertical feed pipe to add reaction materials. This feeding method has the potential risk of materials adhering to the inner wall of the feed pipe, making it impossible to ensure that the materials completely enter the reactor. This increases the difficulty of controlling the material ratio and affects the subsequent curing efficiency of the phenolic resin material. On the other hand, using air pressure to assist in adding materials is directly limited by air pressure, which reduces the accuracy of material ratio control. Furthermore, it is directly limited by the viscosity of the materials, thus affecting the practicality of the phenolic resin material preparation reactor. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, to provide a phenolic resin material preparation reactor, to improve the accuracy of raw material addition, to reduce the risk of raw material residue in the drop path during the raw material addition process, and to improve the accuracy of controlling the proportion of raw materials inside the reactor.

[0005] This utility model also provides a reaction vessel for preparing the above-mentioned phenolic resin material, comprising: a tank body, two opposing steam inlets fixedly connected to the upper end of the side surface of the tank body, a discharge port and a condensate outlet fixedly connected to the lower end of the tank body, a stirring mechanism, a thermometer, and a pressure regulating mechanism fixedly connected to the upper surface of the tank body, a feed inlet and a vertical plate fixedly connected to the upper surface of the tank body, a glass tube disposed above the feed inlet, a graduated strip fixedly connected to the front end of the side surface of the glass tube, an electric valve fixedly connected between the glass tube and the feed inlet, feeding pipes fixedly connected to the upper and lower ends of the side surface of the glass tube, a piston disposed inside the glass tube, and an automatic telescopic rod fixedly connected to the front surface of the vertical plate, the output end of the automatic telescopic rod being fixedly connected to the upper surface of the piston. This reduces the amount of raw material residue during the feeding process and improves the accuracy of controlling the proportion of added raw materials.

[0006] According to the phenolic resin material preparation reactor of this utility model, a support is fixedly connected to the lower end of the tank body, and a reinforcing shell is fixedly connected to the upper surface of the tank body. The upper end of the stirring mechanism is located inside the reinforcing shell. This improves the stability of the reactor.

[0007] According to the phenolic resin material preparation reactor of this utility model, an isolation cover is fixedly connected to the front surface of the vertical plate, and the glass tube is in contact with the inner wall of the isolation cover. This reduces the risk of damage to the glass tube.

[0008] According to the phenolic resin material preparation reactor of this utility model, the isolation cover is fixedly connected to the vertical plate by screws, and the isolation cover is composed of an arc-shaped plate made of transparent silicone and two flat plates. This improves the effectiveness of the isolation cover.

[0010] According to the phenolic resin material preparation reactor of this utility model, an exhaust pipe is fixedly connected to the lower end of the side surface of the glass tube, and the exhaust pipe is inclined to the lower right. This reduces the amount of raw materials entering the exhaust pipe.

[0011] According to the phenolic resin material preparation reactor of this utility model, the length of the output end of the automatic telescopic rod is greater than the length of the glass tube. After the output end of the automatic telescopic rod is fully extended, the piston contacts the connection node between the glass tube and the electric valve.

Detailed Implementation

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-6 This utility model embodiment of a phenolic resin material preparation reactor includes: a tank body 1, a support 2 fixedly connected to the lower end of the tank body 1, two opposing steam inlets 3 fixedly connected to the upper end of the side surface of the tank body 1, the steam inlets 3 being used to increase the internal temperature of the reactor, a discharge port 4 and a condensate outlet 6 fixedly connected to the lower end of the tank body 1, a stirring mechanism 7, a thermometer 17, and a pressure regulating mechanism 18 fixedly connected to the upper surface of the tank body 1, and a reinforcing shell 19 fixedly connected to the upper surface of the tank body 1, the upper end of the stirring mechanism 7 being located inside the reinforcing shell 19. The above components cooperate with each other to form the basic structure of a common reactor, wherein the stirring mechanism 7 consists of a motor, a rotating shaft, and stirring blades, the stirring blades being located inside the tank, and the pressure regulating mechanism 18 consists of a pressure gauge, a gas tank, and a hydraulic valve.

[0025] Specifically, when using the reactor, steam is introduced into the tank 1 through the steam inlet 3 to change the temperature inside the tank 1. The steam that enters the tank and condenses into water droplets is discharged through the condensate outlet 6. The pressure gauge of the pressure regulating mechanism 18 displays the pressure inside the tank in real time.

[0026] A feed inlet 8 and a vertical plate 16 are fixedly connected to the upper surface of the tank body 1. An exhaust pipe 13 is fixedly connected to the lower end of the side surface of the glass tube 10, and the exhaust pipe 13 is inclined to the lower right. The exhaust pipe 13 is used to improve the air pressure of the glass tube 10 and reduce the resistance encountered by the piston 5 during its upward sliding. The exhaust pipe 13 is normally closed to maintain the airtightness of the glass tube 10. The glass tube 10 is located above the feed inlet 8. A scale strip 11 is fixedly connected to the front end of the side surface of the glass tube 10. The glass tube 10 and the scale strip 11 cooperate to provide workers with convenient access to observe the total amount of raw materials to be added. An electric valve 9 is fixedly connected between the glass tube 10 and the feed inlet 8. The upper and lower ends of the electric valve 9 are fixedly connected to the lower end of the glass tube 10 and the feed inlet 8, respectively. The glass tube 10 is fixedly connected to the feed inlet 8 through the electric valve 9, which is used to seal the glass tube 10. Feeding pipes 15 are fixedly connected to the upper and lower ends of the side surface of the glass tube 10, respectively. A piston 5 is installed inside the glass tube 10. An automatic telescopic rod 12 is fixedly connected to the front surface of the vertical plate 16. The output end of the automatic telescopic rod 12 is fixedly connected to the upper surface of the piston 5. The length of the output end of the automatic telescopic rod 12 is greater than the length of the glass tube 10. After the output end of the automatic telescopic rod 12 is fully extended, the piston 5 contacts the connection node between the glass tube 10 and the electric valve 9. The automatic telescopic rod 12 cooperates with the piston 5 to press down the raw material inside the glass tube 10 and transfer the raw material into the tank. An isolation cover 14 is fixedly connected to the front surface of the vertical plate 16. The glass tube 10 contacts the inner wall of the isolation cover 14. The isolation cover 14 is fixedly connected to the vertical plate 16 by screws. The isolation cover 14 is made of a transparent silicone arc plate and two flat plates. The isolation cover 14 reduces the risk of damage to the glass tube 10.

[0027] Specifically, the raw material to be added is added into the glass tube 10 through the feeding tube 15. Since the electric valve 9 closes the bottom of the glass tube 10, the raw material accumulates inside the glass tube 10. After the total amount of raw material is measured by the scale bar 11, the electric valve 9 is released from its restriction on the lower end of the glass tube 10. At the same time, the automatic telescopic rod 12 extends and pushes the piston 5 down. Since the glass tube 10 is in a sealed state and only exists in the same channel inside the tank 1, the piston 5 squeezes the raw material accumulated inside the glass tube 10 during its descent. At the same time, the piston 5 scrapes off the raw material on the inner wall of the glass tube 10 during its descent, thereby preventing the raw material from remaining on the inner wall of the glass tube 10.

[0028] Working principle: The raw material to be added enters the glass tube 10 through the feed port 8. After the raw material has been left to stand for a period of time, the surface of the liquid raw material becomes flat. At this time, the total amount of raw material is judged by referring to the scale bar 11. Then, the electric valve 9 and the automatic telescopic rod 12 are opened to completely transfer the raw material inside the glass tube 10 into the tank 1. When the piston 5 needs to be reset, the bottom of the glass tube 10 is first closed by the electric valve 9, and then the exhaust pipe 13 is opened. At this time, the automatic telescopic rod 12 drives the piston 5 to slide upward and reset. At this time, the internal space of the glass tube 10 is connected to the outside through the exhaust pipe 13, thereby reducing the air pressure resistance encountered by the piston 5 during the upward sliding and reset process. At the same time, when using this device, in order to reduce the risk of contamination of the reactants in the tank, an air source can be connected to the exhaust pipe 13 to provide thrust for the piston 5 to slide upward and reset, thereby reducing the resistance encountered by the piston 5 during the upward sliding process.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
