Description

Technical Field

[0001] This utility model relates to the technical field of crosslinking agent production equipment, and in particular to a reaction vessel for crosslinking agent production. Background Technology

[0002] In the production process of crosslinking agents, the cleanliness of the inner wall of the reactor directly determines the purity of the next batch of products. If the residual material from the previous reaction cannot be completely discharged, it will mix with the new raw materials and cause side reactions, resulting in a decline in product quality or even scrapping. However, traditional reactors used for crosslinking agent production have long faced the problem of "residual materials being difficult to discharge completely and secondary pollution occurring frequently" due to the lack of an effective tilt adjustment structure. Traditional crosslinking agent reactors mostly adopt a "fixed horizontal" design, with the reactor rigidly connected to the supporting structure, making angle adjustment impossible. After the reaction, operators need to discharge most of the product through the bottom discharge pipe and then add cleaning solution to the reactor for rinsing. However, in a horizontal state, there is a natural "low-lying dead corner" at the bottom of the reactor, where cleaning solution and dissolved residual materials tend to accumulate. This results in a small amount of residual material still re-attaching after the wastewater dries. Therefore, the above problems need to be solved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 This utility model discloses a reaction vessel for producing a crosslinking agent, comprising a base plate 1, with two columns 2 symmetrically fixed to the top of the base plate 1, facilitating the installation and integrated support of various components; an operation screen 4 is installed on the top end face of one column 2, allowing for timely feedback of equipment malfunctions and preventing crosslinking agent reaction failure due to parameter deviations; a height adjustment component is provided between the two columns 2, with a vessel lid fixed to the height adjustment component, and a reaction vessel 5 located at the bottom of the vessel lid, allowing the reaction vessel 5 to withstand the acid and alkaline environment during the crosslinking agent reaction without the risk of raw material contamination; a flange is provided between the reaction vessel 5 and the vessel lid, and two support blocks 6 are symmetrically welded to the outer periphery of the reaction vessel 5, ensuring balanced force on the reaction vessel 5 and preventing local stress concentration during tilt adjustment; a connecting block 7 is fixed to the bottom of each support block 6, and the connecting block 7 is equipped with an adjustment component for controlling the tilt of the reaction vessel 5.

[0015] In this invention, the height adjustment component includes two mounting slots respectively opened on the opposite sidewalls of the top of two columns 2. A lead screw 3 is installed in one mounting slot, and a guide rod is fixedly connected to the other mounting slot. A second motor is installed on the top of one column 2, and the output end of the second motor is coaxially fixedly connected to the lead screw 3. The height adjustment component facilitates the opening and closing of the reactor lid and the reactor vessel 5, and the height adjustment meets the precise height requirements for reaction observation in crosslinking agent production. A rotating shaft is provided at the bottom of the reactor lid, and a spiral stirring paddle 11 is coaxially fixedly connected to the rotating shaft. A mounting sleeve is bolted to the bottom of the reactor 5. Scrapers 12 are fixed to both sides of the mounting sleeve. The scrapers 12 are adapted to the inner wall of the bottom of the reactor 5. The spiral stirring paddle 11 facilitates the effective shortening of the crosslinking agent reaction time, realizes three-dimensional mixing of raw materials, and ensures the full reaction of the crosslinking agent. A first motor 9 is installed upside down in the middle of the top surface of the reactor lid. The output end of the first motor 9 is coaxially fixed to the rotating shaft. A sealed bearing is installed at the connection between the output end of the first motor 9 and the reactor lid. Four feed pipes 13 are axially arrayed and fixed to the reactor lid. Two supports are symmetrically welded to both sides of the top of the reactor lid. The plate allows for the separate addition of different types of raw materials via the feed pipe 13, preventing cross-contamination and facilitating control of the addition speed and amount. The adjusting component includes two rotating shafts fixed to one side of two connecting blocks 7. One rotating shaft is rotatably connected to one side of the middle section of a column 2, and the other rotating shaft is rotatably connected to one side of the middle section of another column 2. The middle section of the other column 2 has a rotating groove, within which a rotating rod is rotatably mounted. A handwheel 14 is fixedly connected to the top of the rotating rod, and a worm gear is fixedly connected to the bottom of the rotating rod. The other rotating shaft extends into the rotating groove. One end of the inner part is fixedly connected to a turbine 10, which meshes with a worm gear. The rotational motion of the worm gear can be easily converted into the rotation of the rotating shaft through the adjustment component, thereby driving the reactor 5 to tilt around the rotating shaft and precisely tilting the reactor 5. Multiple threaded holes are equally spaced on one end face of the middle part of the column 2. A pin 8 is inserted into the handwheel 14 to limit the rotation of the handwheel 14. The bottom of the pin 8 is screwed into the threaded hole, and the top of the pin 8 is provided with a twist. The pin 8 helps to prevent the handwheel 14 from rotating and the angle of the reactor 5 from shifting due to vibration during the reaction process.

[0016] Working Principle: When using this utility model, firstly, each electrical component in this application is connected to the power source. Then, the device uses the base plate 1 as the basic supporting frame. Its high-strength material and large contact area design ensure that the entire reactor 5 has no risk of tipping over or significant vibration during operation. During the commissioning phase, the operator first completes the core parameter setting through the operation screen 4 on top of one of the columns 2. Next, the raw material addition is achieved through the four feed pipes 13 axially arrayed on the reactor lid. This design can correspond to different types of raw materials required for crosslinking agent production, effectively avoiding mutual contamination and ratio deviation when multiple raw materials are mixed and added. The operator adds the raw materials according to the preset formula ratio. Raw materials are added simultaneously or in stages through each feed pipe 13: For liquid raw materials, the diameter of the feed pipe 13 is adapted to its flowability, enabling uniform addition; for powder raw materials, the enlarged pipe opening design reduces scattering and ensures accurate placement of the raw material into the reactor 5. After each raw material is added, the sealing cap at the top of the feed pipe 13 is closed promptly to prevent external dust and impurities from entering the reactor 5 and affecting the purity of the crosslinking agent, and to avoid gas leakage during subsequent reactions, ensuring operational safety. If it is necessary to observe the total amount of raw material in the reactor 5 or adjust the addition position during the addition process, the second motor can be controlled via the operation panel 4 to fine-tune the height of the reactor lid. Then, the output end of the first motor 9 is connected via a sealed bearing. The rotating shaft at the bottom of the reactor lid drives the coaxially fixed spiral agitator 11 and bottom scraper 12 to move. The spiral agitator 11 adopts a three-dimensional spiral structure, which can turn the raw material at the bottom of the reactor 5 upward when rotating, and at the same time transport the raw material at the top downward, forming an up-and-down circulating raw material flow trajectory. The scraper 12 is fixed to the bottom of the spiral agitator 11 by the mounting sleeve, and its two sides are precisely adapted to the inner wall of the bottom of the reactor 5. When rotating with the agitator, it can not only scrape off the raw material residue attached to the bottom of the reactor, but also push the residual raw material to flow towards the center of the reactor 5, further assisting the agitator to achieve mixing without dead corners. Finally, the product discharge and cleaning and maintenance of the reactor 5 are controlled by the operation screen. 4. Stop the first motor 9. After the spiral agitator 11 and scraper 12 have completely stopped, open the discharge pipe valve at the bottom of the reactor 5 to discharge the material. After the material is discharged, close the bottom discharge pipe valve. Then rotate the handwheel 14. The handwheel 14 drives the rotating rod and the bottom worm gear to rotate. The worm gear meshes with the turbine 10 to drive the rotating shaft to tilt the reactor 5 around the rotating shaft. Add an appropriate amount of cleaning solution to thoroughly rinse the reactor wall, agitator and scraper 12. Discharge the cleaning wastewater completely to ensure that the inner wall of the reactor 5 is clean and free of residue, and to avoid cross-contamination of raw materials from different batches. Then reset the equipment to prepare for the next round of crosslinking agent production. The use of the reactor for crosslinking agent production is now complete.
