A reaction vessel with an additive-preventing wall-mounted filling pipe

Abstract

This utility model relates to a reactor with an anti-adhesion additive filling pipe, comprising a reactor body and a multi-stage telescopic filling pipe. The reactor body has an inlet at the top, and the multi-stage telescopic filling pipe is detachably installed at the inlet via a quick-release flange. The end of the multi-stage telescopic filling pipe extends into the reactor. By installing the multi-stage telescopic filling pipe inside the reactor, which is detachably connected to the filling port and used for conveying additives, the multi-stage telescopic filling pipe avoids forming a curved surface with the inner wall of the reactor, allowing additives to drip directly onto the solvent surface during addition. The extension and retraction of the multi-stage telescopic filling pipe is driven by a drive assembly. Simultaneously, a level gauge is used to detect the solvent level inside the reactor, obtaining the level information and transmitting it to a control terminal. The control terminal can control the drive assembly in real-time to adjust the position of the multi-stage telescopic filling pipe, ensuring that the outlet end of the multi-stage telescopic filling pipe forms the optimal anti-splash height with the solvent surface inside the reactor.

Description

Technical Field

[0001] This utility model belongs to the field of reaction vessels, specifically designed as a reaction vessel with a wall-mounted injection pipe that prevents additives from adhering to the vessel wall. Background Technology

[0002] Traditional additive filling ports are connected to the inside and outside of the reactor by a pipe, allowing additives to be smoothly added into the solvent stored inside the reactor. Because the pipe opening and the inner wall of the reactor form a continuous curved surface, the additives flow downwards along the inner wall of the reactor during addition. The additives (such as resins and waxes) will solidify inside the reactor during preheating. The solidified additives are difficult to clean and also affect the accuracy of additive addition in the product. In addition, due to the elevation difference between the filling port and the solvent stored in the reactor, the additives will hit the solvent surface during addition, causing the solvent and added additives to splash onto the inner wall of the reactor, increasing the difficulty of cleaning and affecting the accuracy of additive addition.

[0021] 2. Multi-stage telescopic filling pipe. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] The following is combined Figure 1-3This invention describes a specific embodiment of a reactor with an anti-adjuvant wall-hanging filling pipe, comprising a reactor body 1 and a multi-stage telescopic filling pipe 2. By installing a telescopic multi-stage telescopic filling pipe 2 inside the reactor body 1 for adding adjuvants, on the one hand, the discharge end of the multi-stage telescopic filling pipe 2 avoids the inner wall of the reactor body 1, preventing the adjuvant from condensing and solidifying as it flows downwards along the inner wall of the reactor body 1; on the other hand, by reducing the distance between the discharge end of the multi-stage telescopic filling pipe 2 and the fluid surface inside the reactor body 1, splashing of the fluid inside the reactor body 1 during adjuvant addition is avoided, preventing splashing onto the inner wall of the reactor body 1 and causing condensation and solidification. The reactor body 1 has a feed inlet 11 at the top. The injection tube 2 is detachably installed on the feed inlet 11 via the quick-release flange 112. The multi-stage telescopic injection tube 2 is installed on the feed inlet 11 via the quick-release flange 112. After the additive is added, the multi-stage telescopic injection tube 2 can be disassembled using the quick-release structure of the quick-release flange 112 to clean the residual additives adhering to the multi-stage telescopic injection tube 2 regularly, so as to avoid affecting the next addition of additives or the additives solidifying and causing the multi-stage telescopic injection tube 2 to be unable to extend or retract. The end of the multi-stage telescopic injection tube 2 extends into the interior of the reactor, and its tube body is composed of at least three nested sleeves. Adjacent sleeves can slide relative to each other along the axial direction. The multi-stage telescopic injection tube 2 can reduce the space occupied by this structure in the reactor body 1, while providing a longer extension stroke.

[0025] The top of the outer side of the reactor is provided with a drive assembly 12. The output end of the drive assembly 12 is connected to the bottom of the innermost sleeve of the multi-stage telescopic filling tube through a connector 13. It is used to drive the innermost sleeve to move axially to drive the extension and retraction of the entire multi-stage telescopic filling tube 2. The output end of the drive assembly is connected to the bottom of the multi-stage telescopic filling tube 2. It is used to drive the extension and retraction of the multi-stage telescopic filling tube 2 inside the reactor body 1 to reduce the distance between the bottom of the multi-stage telescopic filling tube 2 and the liquid surface of the fluid inside the reactor body 1. This prevents the additive from dripping onto the fluid and splashing onto the inner wall of the reactor body 1 and solidifying and sticking when it is being transported.

[0026] A level gauge 14 is provided at the top of the inner wall of the reactor. The detection end of the level gauge 14 faces the liquid surface inside the reactor body and is used to control the movement path of the multi-stage telescopic filling pipe 2. The level gauge 14 detects the liquid level inside the reactor body 1 and transmits the detection data to the control terminal to obtain the telescopic displacement of the multi-stage telescopic filling pipe 2, so that the bottom of the multi-stage telescopic filling pipe 2 forms the optimal distance with the liquid surface inside the reactor body 1, thereby reducing the amount of splashing during the delivery of additives.

[0027] Please refer to Figures 1-2As shown, the feed inlet 11 has a mounting hole 111 for installing the quick-release flange 112. The outermost sleeve of the multi-stage telescopic filling pipe 2 is detachably installed with the feed inlet 11 through the quick-release flange 112. The quick-release flange 112 is installed with the reactor body 1 by bolts and threaded installation with the mounting hole 111. The top of the multi-stage telescopic filling pipe 2 is fixedly connected to the quick-release flange 112.

[0028] Please refer to Figures 1-2 As shown, the drive assembly 12 includes an electric telescopic rod 121 fixedly connected to the outer side of the top of the reactor body 1. The output end of the electric telescopic rod 121 passes through the reactor body 1 and extends into its interior, and is connected to the bottom of the innermost sleeve of the multi-stage telescopic filling pipe 2 through a connector 13.

[0029] Please refer to Figure 2 As shown, the connector 13 includes a connecting plate 131, a through groove 132 formed on the connecting plate 131, and an installation step 133 formed on the top of the through groove 132. The bottom of the innermost sleeve of the multi-stage telescopic filling tube 2 is inserted into the through groove 132 and abuts against the installation step 133. One end of the connecting plate 131 is fixed to the bottom of the innermost sleeve of the electric telescopic rod 121, and the other end is connected to the innermost sleeve of the multi-stage telescopic filling tube 2 by forming the installation step 133 in the through groove 132. The telescopic movement of the electric telescopic rod 121 drives the telescopic movement of the multi-stage telescopic filling tube 2 within the reactor body 1, ultimately changing the distance between the additive outlet and the liquid surface of the fluid in the reactor body 1 to avoid splashing of the fluid in the reactor body 1 when adding additives. The drive assembly 12 drives... In the first embodiment of the telescopic filling tube 2, the bottom of the innermost sleeve of the telescopic filling tube 2 overlaps on the mounting step 133 formed on the connecting plate 131. When the additive has a low consistency, the telescopic filling tube 2 can fall downwards under its own weight. At the same time, during the delivery of the additive in the telescopic filling tube 2, the impact force will impact the separation between the multi-stage sleeves in the telescopic filling tube 2, avoiding the phenomenon that the sleeves cannot be separated. Therefore, the overlap of the connecting plate 131 only needs to provide a load-bearing support drive for its retraction, which can eliminate the need to set a power source to drive the separation of the multi-stage telescopic filling tube 2. The non-fixed connection between the innermost sleeve of the telescopic filling tube 2 and the connecting plate 131 can realize the detachable installation of the multi-stage telescopic filling tube 2 on the feed port 11.

[0030] Please refer to Figure 2As shown, in another embodiment of the connection between the connecting plate 131 and the innermost sleeve of the multi-stage telescopic filling tube 2, when the viscosity of the conveying additive is high, the multi-stage sleeves of the multi-stage telescopic filling tube 2 may separate and fall off due to the viscosity of the additive. Ultimately, this will cause the multi-stage telescopic filling tube 2 to fail to separate and fall off without a driving force. By fixing an electromagnet 134 in the mounting step 133, the electromagnet 134 can be magnetically connected to the bottom of the innermost sleeve of the multi-stage telescopic filling tube 2. When the electromagnet 134 is energized, it generates a magnetic force, causing the innermost sleeve of the multi-stage telescopic filling tube 2 to separate and fall off. The bottom of the sleeve is magnetically attracted to the connecting plate 131. After the magnetic connection, the downward extension and retraction of the electric telescopic rod 121 will synchronously drive the separation between the multi-stage sleeves in the multi-stage telescopic filling tube 2, so that the separation is not affected by the viscosity of the additive. At the same time, when the multi-stage telescopic filling tube 2 is removed and cleaned at the feed port 11, the electromagnet 134 can be de-energized to make it lose the magnetic attraction force on the innermost sleeve of the multi-stage telescopic filling tube 2, so that the connecting plate 131 and the multi-stage telescopic filling tube 2 can be separated. It should be noted that the energized wire harness of the electromagnet 134 is wrapped with a protective layer to protect it from high temperature, corrosion and other effects.

[0031] Please refer to Figure 1 As shown, a stirring assembly 15 is rotatably installed inside the reactor. The multi-stage telescopic filling pipe 2 avoids the movement range of the stirring assembly 15 and forms a gap with the inner wall of the reactor. The multi-stage telescopic filling pipe 2 is set inside the reactor body 1 to avoid the rotation range of the stirring assembly 15, so that the stirring assembly 15 inside the reactor body 1 can still add additives in the working state. The reactor body 1 is a stirring and storage device for different materials and is a non-vacuum stirring chamber.

[0032] Please refer to Figure 1 As shown, the level gauge 14 is an ultrasonic level gauge 14 or a microwave radar level gauge 14. The level gauge 14 can detect the approximate height of the fluid in the reactor body 1 and transmit the detected data to the control terminal to realize the real-time adjustment of the height difference between the discharge end of the multi-stage telescopic filling pipe 2 and the fluid in the reactor body 1, so as to avoid the amount of splashing caused by the addition of additives.

[0033] Please refer to Figure 3As shown, the bottom of the innermost sleeve of the multi-stage telescopic filling tube is equipped with an adjustable rotating head 122. The rotating head 122 is connected to the multi-stage telescopic filling tube, and its maximum diameter is smaller than the diameter of the feed port 11. The rotating head 122 forms an angle with the axis of the multi-stage telescopic filling tube. The rotating head 122 is used to change the conveying direction of the additive flowing out of the reactor body 1. The rotating connection structure between the rotating head 122 and the bottom of the innermost sleeve of the multi-stage telescopic filling tube 2 is a conventional technical means, and its rotation has a certain damping to prevent the angle of the rotating head 122 from automatically changing due to impact force during the flow of the additive.

[0034] Working principle of this utility model:

[0035] When adding additives, a multi-stage telescopic filling pipe 2 is installed into the feed inlet 11. The multi-stage telescopic filling pipe 2 is detachably installed on the feed inlet 11 via a quick-release flange 112. During the installation of the multi-stage telescopic filling pipe 2, the bottom of the innermost sleeve of the multi-stage telescopic filling pipe 2 overlaps with the installation step 133 formed in the connecting plate 131, so that the electric telescopic rod 121 can drive the multi-stage telescopic filling pipe 2 to perform multi-stage telescopic expansion and contraction through the connection of the connecting plate 131.

[0036] The level gauge 14 detects the liquid level of the fluid stored in the reactor body 1. By acquiring the detection data and transmitting it to the control terminal, the control terminal analyzes the data to obtain the telescopic distance corresponding to the multi-stage telescopic filling tube 2. At this time, the electric telescopic rod 121 receives the drive signal and controls the extension and retraction of its output end. The connecting plate 131 at the telescopic end of the electric telescopic rod 121 supports and bears the telescopic end of the multi-stage telescopic filling tube 2. The downward movement of the multi-stage telescopic filling tube 2 is blocked. Therefore, the downward movement distance of the output end of the electric telescopic rod 121 corresponds to the telescopic distance of the multi-stage telescopic filling tube 2. By controlling the operation of the electric telescopic rod 121, the distance between the bottom of the multi-stage telescopic filling tube 2 and the liquid surface in the reactor body 1 can be reduced, avoiding the fluid remaining in the reactor body 1 from splashing onto the inner wall of the reactor body 1 and solidifying and adhering during the outflow of the additive at the bottom of the multi-stage telescopic filling tube 2.

[0037] In the connection between the connecting plate 131 and the innermost sleeve of the multi-stage telescopic filling tube 2, the first embodiment is that the bottom of the innermost sleeve of the multi-stage telescopic filling tube 2 is directly overlapped with the connecting plate 131. The multi-layer sleeves in the multi-stage telescopic filling tube 2 can be separated from each other under its own weight and the impact of fluid transportation. The connecting plate 131 is used to drive its retraction and reset after telescopic expansion.

[0038] In another embodiment of the connection between the connecting plate 131 and the multi-stage telescopic filling tube 2, since the fluid transported by the multi-stage telescopic filling tube 2 has high viscosity, it will affect the self-separation and falling of the multi-stage sleeves of the multi-stage telescopic filling tube 2. By connecting the lower end of the telescopic filling tube 2 to the connecting plate 131 through magnetic attraction, the electric telescopic rod 121 can provide driving force for the separation of the multi-stage sleeves of the multi-stage telescopic filling tube 2 when it extends and retracts downward. Even after the electromagnet 134 is de-energized, the connection plate 131 and the multi-stage telescopic filling tube 2 can still be separated, so as to facilitate the detachable installation of the multi-stage telescopic filling tube 2 on the feed port 11.

[0039] The level gauge 14 detects the liquid level of the fluid inside the reactor body 1. By analyzing and transmitting the detection data, the control terminal controls the extension distance of the multi-stage telescopic filling pipe 2 to adapt to the changes in the liquid level of the fluid inside the reactor body 1. This ensures that the discharge end of the multi-stage telescopic filling pipe 2 and the liquid level of the fluid inside the reactor body 1 always maintain the optimal distance, so as to avoid the fluid inside the reactor body 1 splashing onto the inner wall and solidifying when the additive is added.
