Description

Technical Field

[0001] This application belongs to the field of adhesive preparation equipment technology, and in particular relates to an adhesive preparation reaction device based on steam heating. Background Technology

[0002] In adhesive manufacturing, a tank-shaped reaction vessel is commonly used. When the reactants inside the vessel are reacting, a certain temperature needs to be reached. In the patent application document with application number 202421262812.9, a technical solution is used to heat the vessel body by using a spiral coil as a heating element. However, spiral coils are difficult to manufacture, and they are installed in sections, making alignment during installation difficult and resulting in high overall costs. In addition, when discharging materials from the adhesive manufacturing reaction vessel, the temperature inside the vessel will drop, and the adhesive may solidify due to the temperature drop in the conveying path, affecting its flow in the pipeline. Utility Model Content

[0003] In order to solve the above problems, this application provides a glue-making reaction apparatus based on steam heating.

[0004] The purpose of this application is to provide a glue-making reaction device based on steam heating, which introduces steam into a crisscrossing steam pipe, and with the help of a bottom ring and distributed steam pipes, achieves rapid and distributed steam intake, thereby raising the temperature of the reaction vessel. The solidified and agglomerated glue is filtered in a buffer filter tank, and the prepared glue is transported from the feed pipe to the storage tank under the action of the drive device.

[0005] To achieve the purpose of this application, the technical solution of this application is as follows:

[0006] A steam-heated adhesive-making reaction device includes a reactor, a buffer filter tank installed on the discharge pipe of the reactor, and horizontally arranged steam pipes at intervals around the outer periphery of the reactor, which are connected together by longitudinal steam pipes. A distributed steam pipe is installed at the bottom of the reactor, and the bottom ends of the distributed steam pipes are connected together by a bottom ring. The top ends of the distributed steam pipes are connected to the longitudinal or horizontal steam pipes. The bottom ring is connected to an inlet steam pipe. An outlet steam pipe is installed on the longitudinal or horizontal steam pipes. An outer filter screen is installed inside the buffer filter tank, and an inner filter screen is installed inside the outer filter screen.

[0007] Furthermore, a steel braided pipe is installed between the discharge pipe of the reactor and the buffer filter tank.

[0008] Furthermore, the outlet of the buffer filter tank is connected to the inlet of the drive unit via a pipe, and the outlet of the drive unit is equipped with a material conveying pipe.

[0009] Furthermore, a connecting flange is provided at the center of the top of the reactor body, and a stirring device is provided on the connecting flange, with the stirring shaft of the stirring device located inside the reactor body.

[0010] Furthermore, a column is installed at the lower end of the vessel body, and a weighing module is installed at the lower end of the column.

[0011] Furthermore, the tank body is equipped with wing plates inside, and a connecting plate is installed at the top of the outer filter screen, with the connecting plate being fixedly connected to the wing plates.

[0012] Furthermore, an annular plate is provided at the top of the inner filter screen, and the annular plate is fixedly connected to the connecting disc.

[0013] Furthermore, a conical cylinder is provided at the upper end of the inner filter screen.

[0014] Furthermore, the filtration accuracy of the inner filter is less than that of the outer filter.

[0015] Furthermore, the lower ends of both the outer and inner filter screens are hemispherical.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] 1. The reaction vessel for making adhesives in this application is provided with a transverse steam pipe on its outer periphery. The transverse steam pipe is connected together by vertically arranged longitudinal steam pipes. The steam inlet pipe enters the distributed steam pipe through the bottom ring at the bottom end of the reaction vessel, and then enters the longitudinal steam pipe and the transverse steam pipe from the distributed steam pipe, thereby raising the temperature of the reaction vessel and heating the reaction vessel with steam. In addition, this heating structure can increase the volume of the reaction vessel.

[0018] 2. Formaldehyde is one of the commonly used raw materials for making adhesives. A large amount of steam is generated in the production of formaldehyde and paraformaldehyde. This application can utilize this steam to save heating costs.

[0019] 3. In this application, a steel braided pipe is placed between the discharge pipe of the reactor and the buffer filter tank to reduce the vibration generated when the glue flows in the pipe. The glue enters the buffer filter tank to filter the solidified and agglomerated glue, and is then transported from the conveying pipe to the storage tank under the action of the driving device.

[0033] Example 1

[0034] This embodiment is a glue-making reaction device based on steam heating. A large amount of steam is generated during the production of formaldehyde or paraformaldehyde. Formaldehyde and paraformaldehyde are raw materials for the production of some glue substances. Therefore, some of the steam is used in the production of glue, replacing the heat transfer oil currently used with steam, thereby reducing the cost of glue production.

[0035] like Figure 1-Figure 3As shown, the adhesive production reaction apparatus of this embodiment includes a reaction vessel 10, a buffer filter, and a drive device 40. The reaction vessel 10 is the production reaction container for adhesive. The buffer filter reduces the amount of coagulated adhesive before it enters the drive device 40, and the drive device 40 transports the adhesive into the storage tank.

[0036] Specifically, such as Figure 1-Figure 2 As shown, the reactor 10 of this embodiment has a vessel body 11. Horizontal steam pipes 12 are spaced apart on the outer periphery of the vessel body 11. The horizontal steam pipes 12 are connected together by vertical steam pipes 18. A distributed steam pipe 17 is installed at the bottom of the reactor 10. The bottom ends of the distributed steam pipes 17 are connected together by a bottom ring. The top ends of the distributed steam pipes 17 are connected to either the vertical steam pipe 18 or the horizontal steam pipe 12. The bottom ring is connected to an inlet steam pipe 14. An outlet steam pipe 15 is installed on either the vertical steam pipe 18 or the horizontal steam pipe 12. This horizontal and vertical arrangement... The installation and processing costs of the arranged pipes are lower. Compared with spiral pipes, the steam flow is smoother and can be arranged more widely on the outer periphery of the vessel 11, avoiding the use of heat transfer oil. The vessel 11 can be heated by steam alone. In this embodiment, the steam inlet pipe 14 enters the distributed steam pipe 17 through the bottom ring of the bottom end of the reactor 10, and then enters the longitudinal steam pipe 18 from the distributed steam pipe 17 and the transverse steam pipe 12, which raises the temperature of the reactor 10. The reactor 10 is heated by steam, and the steam after use flows out from the steam outlet pipe 15 on the uppermost transverse steam pipe 12.

[0037] The reactor body 11 of the reactor vessel 10 has a connecting flange at the top center, and a stirring device is installed on the connecting flange. The stirring shaft of the stirring device is arranged inside the reactor body 11. Since the stirring device occupies the top position of the reactor body 11, the feed pipe 13 in this embodiment is arranged at the top of the reactor body 11, but on one side of the stirring device. As a metering scheme, the lower end of the reactor body 11 has a column, and a weighing module 19 is installed at the lower end of the column. In addition, in this embodiment, a support column is installed on the ground, and the weighing module 19 is fixed on the support column. The column is installed on the weighing module 19, so that the reactor body 11 is away from the ground and provides space for the arrangement of the storage tank, the steam inlet pipe 14, and the buffer filter tank 30.

[0038] In this embodiment, the discharge pipe 16 of the reactor 10 is equipped with a buffer filter tank 30. As a buffer structure, a steel braided pipe 20 is installed between the discharge pipe 16 and the buffer filter tank 30 of the reactor 10 in this embodiment. The steel braided pipe 20 is a steel braided pipe with flanges at both ends.

[0039] like Figure 3As shown, the buffer filter tank 30 of this embodiment includes a tank body 31. An outer filter screen 33 is installed inside the tank body 31 of the buffer filter tank 30, and an inner filter screen 32 is installed inside the outer filter screen 33. The filtration accuracy of the inner filter screen 32 is less than that of the outer filter screen 33, that is, the mesh size of the inner filter screen 32 is larger than that of the outer filter screen 33. During disassembly, since the inner filter screen 32 is easier to disassemble, this embodiment can remove the inner filter screen 32 by means of the cooperation between the inner filter screen 32 and the outer filter screen 33, thus reducing the number of times the outer filter screen 33 needs to be disassembled.

[0040] Specifically, as an installation scheme, the tank 31 in this embodiment has annular wing plates inside. The outer filter screen 33 has a connecting plate at its top, which is fixedly connected to the wing plates. The inner filter screen 32 has annular plates at its top, which are fixedly connected to the connecting plates. The fixed connection scheme is bolt connection. Therefore, during disassembly, the inner filter screen 32 can be removed without removing the outer filter screen 33. Since the inner filter screen 32 has a small accommodating space, in order to avoid slow filtration of the glue in the inner filter screen 32, the upper end of the inner filter screen 32 in this embodiment has a conical cylinder to increase the overall space of the inner cavity of the inner filter screen 32. The lower ends of the outer filter screen 33 and the inner filter screen 32 are hemispherical to collect the coagulated glue.

[0041] The outlet of the buffer filter tank 30 is connected to the inlet of the drive device 40 via a pipe. The outlet of the drive device 40 is equipped with a conveying pipe 50. The inlet of the buffer filter tank 30 is located on the upper side of the buffer filter tank 30. A pipe is installed at the inlet and aligned with the inner filter screen 32. The pipe installed at the inlet can be aligned with the quick-clamp connector at the inlet of the tank body 31 via a quick-clamp connector and connected by a clamp. The outlet of the buffer filter tank 30 is located on the lower side of the tank body 31. The length of the pipe between the outlet of the buffer filter tank 30 and the inlet of the drive device 40 is minimized.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0043] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
