Description

Technical Field

[0001] The utility model relates to the technical field of hydrolysis kettles, in particular to a structure of the discharge port of a hydrolysis kettle. Background Technique

[0002] The main function of the hydrolysis kettle is to promote the full mixing and reaction of various substances in the hydrolysis reaction under specific temperature and pressure conditions, so as to produce the required products.

[0003] The discharge port of the hydrolysis kettle is arranged directly below the kettle body. In order to facilitate the control of the opening and closing of the discharge port, a liquid valve is arranged on the pipeline connected to the discharge port. Due to a certain gap between the liquid valve and the bottom of the kettle, the reaction materials are likely to be retained in the connecting pipeline between the two. Due to the position of this part of the retained materials, it is difficult to be effectively acted on by the stirring shaft and fully mixed with the materials in the kettle body, affecting the hydrolysis of the materials.

[0004] Therefore, it is very necessary to propose a structure of the discharge port of a hydrolysis kettle to solve the above problems. Content of the Utility Model

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model. Apparently, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.

[0025] Please refer to Figures 1-3As shown in the figure, a structure of the discharge port of a hydrolysis kettle includes a kettle body 2. At the discharge port at the bottom end of the kettle body 2, a connecting pipe 4 is fixedly connected. A transmission rod 10 is slidably connected inside the connecting pipe 4. One end of the transmission rod 10 extends into the kettle body 2 and is fixedly connected with a head 6. The head 6 is used to seal the discharge port. The bottom end of the connecting pipe 4 is fixedly connected with a discharge pipe 5. A valve rod 11 is penetrated through the discharge pipe 5 and is rotatably connected with it. One end of the valve rod 11 located inside the discharge pipe 5 is fixedly connected with a threaded cylinder 19. The transmission rod 10 is threadedly connected with the threaded cylinder 19, and the head 6 is driven to lift and lower by the valve rod 11.

[0026] When opening, rotate the valve rod 11. Since the transmission rod 10 is threadedly connected with the threaded cylinder 19 and the transmission rod 10 is slidably connected with the connecting pipe 4, the valve rod 11 drives the head 6 to rise away from the connecting pipe 4. When closing, the head 6 descends to block the discharge port.

[0027] By using the head 6 to seal the discharge port at the bottom end of the kettle body 2, it is avoided that materials remain in the discharge port pipeline, affecting the hydrolysis of the materials. By slidably connecting the transmission rod 10 with the connecting pipe 4, it is possible to prevent the head 6 from rotating and rubbing against the inner wall of the kettle body 2 during the lifting and lowering process, causing wear on the inner wall.

[0028] In order to improve the sealing effect, the lower end surface of the head 6 is adapted to the discharge port at the bottom end of the kettle body 2, and a sealing ring 13 is fixedly connected to the lower end surface of the head 6. Preferably, there are multiple sealing rings 13. By arranging multiple sealing rings 13, the sealing effect between the head 6 and the kettle body 2 is better.

[0029] In some embodiments, a fixing block 14 is fixedly connected to the inner wall of the connecting pipe 4. A sliding groove 15 is opened on the fixing block 14. A limiting rod 17 is fixedly connected to the outer side of the transmission rod 10. The limiting rod 17 is slidably connected with the fixing block 14 through the sliding groove 15.

[0030] The transmission rod 10 is limited by the mutual cooperation of the limiting rod 17 and the sliding groove 15, preventing the transmission rod 10 from rotating along with the valve rod 11.

[0031] In order to limit the rising height of the head 6, a stop block is provided at the top end of the sliding groove 15. When opening, the stop block blocks the limiting rod 17 to prevent the head 6 from continuing to rise and contacting the stirring shaft 3.

[0032] In order to make the assembly more convenient, the transmission rod 10 is a stepped shaft. A sleeve 16 is fixedly connected to the middle of the limiting rod 17. The sleeve 16 is sleeved on the outside of the second step of the stepped shaft and fixed by a positioning bolt.

[0033] During assembly, open the kettle cover 1, place the head 6 inside the kettle body 2, and make the transmission rod 10 pass through the connecting pipe 4. Sleeve the sleeve 16 on the second step of the transmission rod 10 and fix it with a positioning bolt. Under the cooperation of the step of the stepped shaft and the positioning bolt, it is prevented that the limiting rod 17 slides axially along the transmission rod 10.

[0034] To prevent the limiting rod 17 from rotating relative to the transmission rod 10, the second stepped cross-section of the stepped shaft is set to be rectangular, and a through hole adapted to the second stepped cross-section is provided in the middle of the sleeve 16. The two cooperate with each other to prevent the limiting rod 17 from rotating relative to the transmission rod 10.

[0035] Specifically, the discharge pipe 5 is an L-shaped pipe, and a handwheel 12 is fixedly connected to one end of the valve stem 11 located outside the discharge pipe 5. During use, the valve stem 11 is driven to rotate by the handwheel 12 to control the lifting of the sealing head 6 and realize the opening and closing of the discharge port.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
