Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a non-ionic cellulose ether processing reaction vessel with flow limiting function. Background Technology

[0002] In a broad sense, a reaction vessel is a container that carries out physical or chemical reactions. Through structural design and parameter configuration of the container, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved. Reaction vessels are used in the process of processing non-ionic cellulose ethers.

[0003] Chinese patent discloses a reaction vessel for preparing cellulose ethers (authorization announcement number CN217830004U). This patented technology enables the stirring plate to rotate around the rotating shaft while simultaneously adjusting its position, changing the stirring trajectory, increasing the stirring range, and improving the stirring effect. This results in uniform mixing of the raw materials and improves the reaction preparation effect of cellulose ethers.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing reaction vessels are made by putting multiple raw materials into the reaction vessel to make the raw materials undergo chemical reactions inside. In the process of putting raw materials into the reaction vessel, the raw materials that need to be reacted are usually put into the reaction vessel all at once. Since the raw materials will undergo chemical reactions, if too many raw materials are put in at once, the raw materials are prone to violent reactions inside the reaction vessel, thereby creating safety hazards. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the raw materials will undergo chemical reactions. If too much raw material is added at one time, the raw material is prone to violent reaction inside the reaction vessel, which will create safety hazards. To this end, we propose a non-ionic cellulose ether processing reaction vessel with flow limiting function.

[0006] To achieve the above objectives, this application adopts the following technical solution: a non-ionic cellulose ether processing reactor with flow limiting function, comprising a reactor body, a support mounted on the surface of the reactor body, a feed pipe fixedly connected to the top of the reactor body, the interior of the reactor body communicating with the interior of the feed pipe, a discharge pipe installed at the bottom of the reactor body, the interior of the discharge pipe communicating with the interior of the reactor body, a placement groove opened on one side of the feed pipe, a flow limiting plate slidably connected inside the placement groove, the bottom of the flow limiting plate fitting against the top of the reactor body, a limiting groove opened at the top of the reactor body, and a limiting slider fixedly connected to the bottom of the flow limiting plate.

[0007] Preferably, a plurality of limiting grooves are provided on both sides of the limiting slide groove, and a first through groove is provided on one side of the limiting slider, and two limiting plates are slidably connected inside the first through groove.

[0008] Preferably, the flow-limiting plate has a storage groove inside, and a second through groove is formed at the bottom of the storage groove. The inside of the second through groove is slidably connected to the surface of the limiting plate. An elliptical plate is rotatably connected inside the storage groove. A connecting rod is fixedly connected to the top of the elliptical plate. A knob is installed on the top of the connecting rod. Two thrust springs are fixedly connected to one side of the limiting plate. The other end of the thrust springs is fixedly connected to one side of the inside of the storage groove.

[0009] Preferably, the difference between the maximum and minimum diameters of the elliptical plate is greater than the distance the limiting plate is inserted into the limiting groove.

[0010] Preferably, a telescopic rod is slidably connected inside the connecting rod, the top of the telescopic rod is fixed to the bottom of the knob, a limit hole is opened on the top of the flow limiting plate, and a limit block is fixedly connected to the bottom of the knob.

[0011] Preferably, the connecting rod has a first sliding groove on both sides inside, and the telescopic rod has a first slider fixedly connected to both sides.

[0012] Preferably, a tension spring is fixedly connected to the bottom of the telescopic rod, and the bottom of the tension spring is fixedly connected to the top of the elliptical plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the user feeds the non-ionic cellulose ether processing raw material to be reacted into the interior of the reactor body through the feed pipe. During the feeding process, the opening and closing size of the feed pipe is controlled by moving the flow limiting plate. As the flow limiting plate moves, the limiting slider at the bottom of the flow limiting plate slides inside the limiting groove, limiting the movement of the flow limiting plate and preventing the flow limiting plate from detaching from the interior of the placement groove, which would cause raw material leakage. By controlling the feeding speed of the raw material, it is possible to avoid violent internal reactions caused by a large amount of raw material entering the reactor at once, thus avoiding safety risks.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figures 1-3 As shown, this utility model provides a technical solution: a non-ionic cellulose ether processing reactor with flow-limiting function, including a reactor body 1, a support 2 mounted on the surface of the reactor body 1, a feed pipe 3 fixedly connected to the top of the reactor body 1, the interior of the reactor body 1 communicating with the interior of the feed pipe 3, a discharge pipe 4 installed at the bottom of the reactor body 1, the interior of the discharge pipe 4 communicating with the interior of the reactor body 1, a placement groove 5 opened on one side of the feed pipe 3, a flow-limiting plate 6 slidably connected inside the placement groove 5, the bottom of the flow-limiting plate 6 fitting against the top of the reactor body 1, and a limiting groove 7 opened on the top of the reactor body 1. The bottom of the flow limiting plate 6 is fixedly connected to a limiting slider 8. The user puts the non-ionic cellulose ether processing raw material to be reacted into the interior of the reactor body 1 through the feed pipe 3 for reaction. During the feeding process, the opening and closing size of the feed pipe 3 is controlled by moving the flow limiting plate 6. During the movement of the flow limiting plate 6, the limiting slider 8 at the bottom of the flow limiting plate 6 slides inside the limiting groove 7 to limit the movement of the flow limiting plate 6 and prevent the flow limiting plate 6 from leaving the interior of the placement tank 5, which would cause raw material leakage. By controlling the feeding speed of the raw material, it is possible to avoid violent internal reactions caused by a large amount of raw material entering the reactor at once, thereby avoiding safety risks.

[0023] Reference Figure 3 and Figure 5As shown in this embodiment: several limiting grooves 9 are provided on both sides of the limiting chute 7, and a first through groove 10 is provided on one side of the limiting slider 8. Two limiting plates 11 are slidably connected inside the first through groove 10. When the user needs to adjust the flow rate of the raw material, he can move the limiting plate 11 to the middle to disengage the limiting plate 11 from the inside of the limiting groove 9, thereby releasing the limiting plate 6 and allowing the limiting plate 6 to move. When the limiting plate 6 moves to the appropriate position, the limiting plates 11 are moved to both sides to enter the inside of the limiting groove 9, thereby limiting the limiting plate 6 and preventing the impact of the falling raw material from causing the limiting plate 6 to shift.

[0024] Reference Figure 4 and Figure 5 As shown in this embodiment: a receiving groove 22 is provided inside the flow-limiting plate 6, and a second through groove 23 is provided at the bottom of the receiving groove 22. The inside of the second through groove 23 is slidably connected to the surface of the limiting plate 11. An elliptical plate 12 is rotatably connected inside the receiving groove 22. A connecting rod 13 is fixedly connected to the top of the elliptical plate 12, and a knob 14 is installed on the top of the connecting rod 13. Two thrust springs 15 are fixedly connected to one side of the limiting plate 11, and the other end of the thrust springs 15 is fixedly connected to one side inside the receiving groove 22. The difference between the maximum diameter and the minimum diameter of the elliptical plate 12 is greater than the distance by which the limiting plate 11 is inserted into the limiting groove 9, and the user needs to adjust it. When the flow restrictor 6 is in position, rotating the knob 14 drives the elliptical plate 12 to rotate, releasing the restriction on the limiting plate 11. Under the thrust of the telescopic rod 16, the limiting plate 11 is pushed to move towards the center, releasing the restriction on the flow restrictor 6, allowing the flow restrictor 6 to move and control the flow rate of the raw material. After adjusting to the appropriate position, rotating the knob 14 drives the elliptical plate 12 to rotate. During the rotation, the elliptical plate 12 pushes the limiting plates 11 on both sides into the interior of the limiting groove 9, limiting the flow restrictor 6. Through the cooperation of the elliptical plate 12 and the thrust spring 15, the movement of the two limiting plates 11 can be controlled simultaneously, making the flow restriction adjustment more convenient.

[0025] Reference Figure 5As shown in this embodiment: a telescopic rod 16 is slidably connected inside the connecting rod 13. The top of the telescopic rod 16 is fixed to the bottom of the knob 14. A limit hole 17 is opened on the top of the flow-limiting plate 6. A limit block 18 is fixedly connected to the bottom of the knob 14. When the user needs to adjust the position of the flow-limiting plate 6, he pulls the knob 14 to make the limit block 18 disengage from the inside of the limit hole 17, thereby releasing the limit on the knob 14. He rotates the knob 14 to release the limit on the flow-limiting plate 6. After moving the flow-limiting plate 6 to a suitable position, he rotates the knob 14 to make the elliptical plate 12 push the limit plate 11 into the inside of the limit groove 9 to limit the flow-limiting plate 6. He presses the knob 14 to insert the limit block 18 into the inside of the limit hole 17 to limit the knob 14, preventing the knob 14 from rotating due to vibration factors, which would cause the limit on the flow-limiting plate 6 to be released.

[0026] Reference Figure 5 As shown in this embodiment: both sides of the connecting rod 13 are provided with first sliding grooves 19, and both sides of the telescopic rod 16 are fixedly connected with first sliders 20. When the user pulls the knob 14, the first sliders 20 on both sides of the telescopic rod 16 move inside the first sliding grooves 19 to limit the movement of the telescopic rod 16 and prevent the telescopic rod 16 from leaving the interior of the connecting rod 13.

[0027] Reference Figure 3 As shown in this embodiment: a tension spring 21 is fixedly connected to the bottom of the telescopic rod 16, and the bottom of the tension spring 21 is fixedly connected to the top of the elliptical plate 12. By installing the tension spring 21 at the bottom of the telescopic rod 16, a continuous tension can be released on the telescopic rod 16 to prevent the telescopic rod 16 from being displaced by factors such as vibration, which would cause the limiting block 18 to disengage from the inside of the limiting hole 17.

[0028] Working principle: The user feeds the nonionic cellulose ether processing raw material to be reacted into the reactor body 1 through the feed pipe 3. During the feeding process, the opening and closing of the feed pipe 3 is controlled by moving the flow restrictor 6. As the flow restrictor 6 moves, the limiting slider 8 at the bottom of the flow restrictor 6 slides inside the limiting groove 7, limiting the movement of the flow restrictor 6 and preventing it from dislodging from the placement tank 5. When it is necessary to adjust the flow rate of the raw material, the limiting plate 11 is moved towards the center, causing the limiting plate 11 to dislodge from the limiting groove 9, thus releasing the limiting effect on the flow restrictor 6. This allows the flow restrictor plate 6 to move. Once the flow restrictor plate 6 is in the appropriate position, the limiting plates 11 move to both sides, allowing them to enter the limiting groove 9 and restrict the flow restrictor plate 6. When the position of the flow restrictor plate 6 needs adjustment, the knob 14 is rotated, causing the elliptical plate 12 to rotate and release the restriction on the limiting plate 11. Under the thrust of the telescopic rod 16, the limiting plate 11 is pushed towards the center, releasing the restriction on the flow restrictor plate 6 and allowing it to move. This controls the flow rate of the raw material. After adjusting to the appropriate position, the knob 14 is rotated, causing the elliptical plate 12 to rotate. During rotation, plate 12 pushes the limiting plates 11 on both sides into the limiting groove 9, limiting the flow limiting plate 6. Through the cooperation of the elliptical plate 12 and the thrust spring 15, the movement of both limiting plates 11 can be controlled simultaneously. When the position of the flow limiting plate 6 needs to be adjusted, pull knob 14 to disengage the limiting block 18 from the limiting hole 17, releasing the limiting of knob 14. Rotate knob 14 to release the limiting of the flow limiting plate 6. After moving the flow limiting plate 6 to the appropriate position, rotate knob 14 to push the elliptical plate 12 into the limiting groove 9, limiting the flow limiting plate 6. Press the knob 14 to insert the limiting block 18 into the limiting hole 17 to limit the knob 14 and prevent it from rotating due to vibration. During the pulling of the knob 14, the first sliders 20 on both sides of the telescopic rod 16 move inside the first slide groove 19 to limit the movement of the telescopic rod 16 and prevent it from disengaging from the connecting rod 13. By installing a tension spring 21 at the bottom of the telescopic rod 16, a continuous tension can be released to the telescopic rod 16 to prevent it from displacing due to vibration or other factors, which would cause the limiting block 18 to disengage from the limiting hole 17.
