Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically to a polyurethane adhesive reaction vessel. Background Technology

[0002] In chemical reactions, the production of polyurethane adhesives is typically carried out in a reaction vessel. Chinese invention patent application CN202511172075.2 discloses a zoned temperature-controlled glass-lined reaction vessel, including the reaction vessel and multiple partition structures. These partition structures divide the interior of the reaction vessel into multiple zones, and are designed to be openable and switchable. A spiral pipe is installed on the inner wall of the reaction vessel, and temperature-regulating structures are installed in each of the multiple zones, adapted to the spiral pipes. This invention achieves dynamic zone switching through horizontally arranged, openable / switching partition structures, allowing for flexible transitions between a single integrated area and multiple independent zones within the reaction vessel. It features dual-stage temperature control linkage: basic temperature regulation via the inner wall spiral pipes; and precise zoned temperature control, where the temperature-regulating structures in each zone activate synchronously when the partition structures are closed, working in conjunction with the spiral pipes. The temperature-regulating structures are steplessly adjustable electronically controlled tubes, enabling independent temperature control of each zone. However, while this reaction vessel has many advantages, the height of the stirring shaft cannot be adjusted. When the amount of material in the reactor is low, the stirring shaft cannot make sufficient contact with the material at the bottom of the reactor, resulting in inadequate stirring. In other words, the stirring shaft can only effectively stir the material when a sufficient amount of reactant is added to the reactor. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polyurethane adhesive reaction vessel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a polyurethane adhesive reaction vessel, comprising: The vessel body; The motor and the stirring shaft are provided. The motor has a rotating shaft connected to the stirring shaft, thereby enabling the motor to drive the stirring shaft to rotate. At least a portion of the stirring shaft extends into the interior of the vessel. A support plate, a connecting sleeve, and a support column; the support plate is connected to the connecting sleeve, the connecting sleeve is sleeved on the support column, and the connecting sleeve is movable up and down on the support column; and An adjustment component is provided, which enables the connecting sleeve to remain at a preset position on the support column, and the adjustment component is also capable of changing the position of the connecting sleeve on the support column.

[0005] Preferably, the adjusting assembly includes a connecting end cap, a nut, and a bolt. The connecting end cap is installed together with the support column. The connecting sleeve is provided with a first connecting plate and a second connecting plate, and there is a preset distance between the first connecting plate and the second connecting plate, so that a second receiving space is formed between the first connecting plate and the second connecting plate. At least a portion of the bolt is installed in the second receiving space. The nut is installed on the connecting end cap on one hand, and is threadedly connected to the bolt on the other hand. The nut can move on the bolt, so that when the nut rotates on the bolt, the bolt drives the first connecting plate and the second connecting plate to move, thereby driving the connecting sleeve to move.

[0006] Preferably, the bolt includes a bolt body and a connecting ball head, the connecting ball head being connected to one end of the bolt body, and the other end of the bolt body being threadedly connected to the nut; the adjusting assembly further includes a pin hole, the pin hole passing through the first connecting plate, the connecting ball head, and the second connecting plate, and being inserted into the pin hole, thereby connecting the bolt to the first connecting plate and the second connecting plate.

[0007] Preferably, the connecting end cap has a first connecting protrusion and a second connecting protrusion, with a preset distance between the first connecting protrusion and the second connecting protrusion, thereby forming a first receiving space between the first connecting protrusion and the second connecting protrusion, and forming an opening between the first connecting protrusion and the second connecting protrusion, the opening communicating with the first receiving space; at least a portion of the bolt passes through the opening and enters the first receiving space; the nut overlaps the first connecting protrusion and the second connecting protrusion.

[0008] Preferably, the system further includes a mounting frame, a support assembly, and a discharge pipe. The vessel body is mounted on the mounting frame, and the discharge pipe is mounted on the mounting frame via the support assembly. The discharge pipe is connected to the vessel body.

The first connecting plate and the clamping plate, and the second connecting plate and the clamping plate are installed together by bolts or screws, thereby enabling the discharge pipe to be installed on the mounting frame.

[0010] Preferably, the mounting sleeve has a connecting flange, and when the clamping plate is installed together with the first connecting plate and the second connecting plate, the connecting flange abuts against the clamping plate; the clamping plate has a slot, and the discharge pipe is inserted into the slot, so that the clamping plate is installed on the discharge pipe.

[0011] Preferably, it also includes a coupling, which is connected to the rotating shaft of the motor on one side and to the stirring shaft on the other side, thereby connecting the stirring shaft to the motor.

[0012] The beneficial effects of this application are as follows: The polyurethane adhesive reactor provided by this application has the advantages of simple structure and easy assembly. Secondly, given the inclusion of an adjustment component, which includes a bolt and nut assembly with a threaded connection between the bolt and nut, rotation of the nut forces the bolt to move, and the movement of the bolt drives the connecting sleeve to rise and fall. The rising and falling of the connecting sleeve, in turn, drives the motor to rise and fall, thereby achieving the purpose of adjusting the height of the stirring shaft. Compared with the prior art, this application can achieve height adjustment of the stirring shaft. When the amount of reactant inside the reactor is small, the stirring shaft can be lowered, thereby enabling the stirring shaft to fully contact the reactant. Attached Figure Description

[0016] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0017] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0018] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0019] Please refer to Figure 1-3 This application provides a polyurethane adhesive reaction vessel (hereinafter referred to as "the reaction vessel"), the reaction vessel comprising: 2. Pot body; The motor 1 has a rotating shaft 100, which is connected to the stirring shaft 3, so that the motor 1 drives the stirring shaft 3 to rotate; at least a portion of the stirring shaft 3 extends into the interior of the vessel body 2. The support plate 6, the connecting sleeve 8, and the support column 10 are provided. The support plate 6 is connected to the connecting sleeve 8, the connecting sleeve 8 is sleeved on the support column 10, and the connecting sleeve 8 is capable of moving up and down on the support column 10. The adjusting component 9 allows the connecting sleeve 8 to stop at a preset position on the support column 10, and also allows the adjusting component 9 to change the position of the connecting sleeve 8 on the support column 10. Thus, the adjusting component 9 allows the connecting sleeve 8 to move on the support column 10 and stop at the desired position, thereby causing the connecting sleeve 8 to rise and fall on the support column 10. When the connecting sleeve 8 rises and falls, it drives the support plate 6 to rise and fall, which in turn drives the motor 1 to rise and fall, thereby driving the stirring shaft 3 to rise and fall. When the stirring shaft 3 rises, it moves away from the bottom of the vessel body 2; when the stirring shaft 3 falls, it moves closer to the bottom of the vessel body 2. In this way, even if there is only a small amount of reactant inside the vessel body 2, the height of the stirring shaft 3 can be lowered to ensure sufficient contact between the stirring shaft 3 and the reactant.

[0020] In some embodiments of this application, please refer to Figure 1-3The adjusting assembly 9 includes a connecting end cap 91, a nut 92, and a bolt 93. The connecting end cap 91 is installed together with the support column 10. The connecting sleeve 8 is provided with a first connecting plate 94 and a second connecting plate 95, with a preset distance between them, thereby forming a second receiving space 96. At least a portion of the bolt 93 is installed in the second receiving space 96. The nut 92 is installed on the connecting end cap 91 and is threadedly connected to the bolt 93. The nut 92 can move on the bolt 93, so that when the nut 92 rotates on the bolt 93, the bolt 93 drives the first connecting plate 94 and the second connecting plate 95 to move, thereby driving the connecting sleeve 8 to move. Thus, when the connecting sleeve 8 moves, it rises and falls on the support column 10, thereby driving the motor 1 to rise and fall, and thus driving the stirring shaft 3 to rise and fall.

[0021] In some embodiments of this application, please refer to Figure 1-3 The bolt 93 includes a bolt body 931 and a connecting ball head 932. The connecting ball head 932 is connected to one end of the bolt body 931, and the other end of the bolt body 931 is threadedly connected to the nut 92. The adjusting assembly 9 also includes a pin hole 97, which passes through the first connecting plate 94, the connecting ball head 932, and the second connecting plate 95. A pin (not shown in the figure) is inserted into the pin hole 97, thereby connecting the bolt 93 to the first connecting plate 94 and the second connecting plate 95. Thus, the bolt 93 being connected to the first connecting plate 94 and the second connecting plate 95 means that the bolt 93 is connected to the connecting sleeve 8. The bolt 93's movement up and down simultaneously drives the connecting sleeve 8 to move up and down.

[0022] In some embodiments of this application, please refer to Figure 1-3The connecting end cap 91 has a first connecting protrusion 911 and a second connecting protrusion 912. A preset distance exists between the first connecting protrusion 911 and the second connecting protrusion 912, thereby forming a first receiving space 913 between them. An opening 910 is formed between the first connecting protrusion 911 and the second connecting protrusion 912, and the opening 910 communicates with the first receiving space 913. At least a portion of the bolt 93 passes through the opening 910 and enters the first receiving space 913. The nut 92 overlaps the first connecting protrusion 911 and the second connecting protrusion 912. Thus, the nut 92 and the bolt 92 are threaded together. By rotating the nut 92, the bolt 92 is forced to rise and fall. Simultaneously, the rising and falling of the bolt 92 drives the connecting sleeve 8 to rise and fall, thereby achieving the rising and falling of the stirring shaft 3.

[0023] In some embodiments of this application, please refer to Figure 1-3 The reactor also includes an installation frame 5, a support assembly 12, and a discharge pipe 11. The reactor body 2 is mounted on the installation frame 5, and the discharge pipe 11 is mounted on the installation frame 5 via the support assembly 12, and the discharge pipe 11 is connected to the reactor body 2.

[0024] In some embodiments of this application, please refer to Figure 1-3 The support assembly 12 includes a first connecting leg 121, a second connecting leg 122, a first connecting plate 123, a second connecting plate 124, a mounting sleeve 125, and a clamping plate 126. One end of the first connecting leg 121 and one end of the second connecting leg 122 are connected to the mounting frame 5. The other end of the first connecting leg 121 is connected to the first connecting plate 123, and the other end of the second connecting leg 122 is connected to the second connecting plate 124. The mounting sleeve 125 is sleeved on the discharge pipe 11, and the clamping plate 126 is clamped on the discharge pipe 11. The first connecting plate 123 and the clamping plate 126, and the second connecting plate 124 and the clamping plate 126 are installed together by bolts or screws, so that the discharge pipe 11 is installed on the mounting frame 5.

[0025] In some embodiments of this application, please refer to Figure 1-3The mounting sleeve 125 has a connecting flange 1251. When the clamping plate 126 is installed together with the first connecting plate 123 and the second connecting plate 124, the connecting flange 1251 abuts against the clamping plate 126. The clamping plate 126 has a slot 1260, and the discharge pipe 11 is inserted into the slot 1260, thereby allowing the clamping plate 126 to be installed on the discharge pipe 11. In this way, the mounting sleeve 125 is installed together with the discharge pipe 11, the clamping plate 126 contacts the mounting sleeve 125, and the clamping plate 126 is lifted by the action of the first connecting leg and the second connecting leg, thereby lifting the mounting sleeve 125 and installing the discharge pipe 11 on the mounting frame 5.

[0026] In some embodiments of this application, please refer to Figure 1-3 The reactor also includes a coupling 4, which is connected to the rotating shaft 100 of the motor 1 on one hand and to the stirring shaft 3 on the other hand, so that the stirring shaft 3 is connected to the motor 1.

[0027] The polyurethane adhesive reactor provided in this application has the advantages of simple structure and easy assembly. Furthermore, given the inclusion of an adjustment component, which includes a bolt and nut assembly with a threaded connection, rotation of the nut forces the bolt to move. This movement of the bolt, in turn, causes the connecting sleeve to rise and fall, which in turn drives the motor to rise and fall, thereby achieving the purpose of adjusting the height of the stirring shaft. Compared to existing technologies, this application can achieve height adjustment of the stirring shaft. When the amount of reactant inside the reactor is low, the stirring shaft can be lowered, allowing for full contact between the stirring shaft and the reactant.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
