Description

Technical Field

[0001] The utility model relates to the technical field of benomyl production, in particular to a synthesis kettle for benomyl production. Background Art

[0002] Benomyl is a systemic fungicide, which is metabolized into carbendazim and another volatile butyl isocyanate in the plant body, which is its main fungicide. The pure product is white crystals with a slight odor. It is insoluble in water, soluble in organic solvents, stable in dry state, and will decompose and lose efficacy when exposed to moisture. It is low toxic to humans and animals and safe to crops.

[0003] During the production of benomyl, a synthesis kettle is required to carry out the synthesis reaction, so various raw materials need to be added into the kettle body for stirring and mixing to mix into qualified quality benomyl. However, when the benomyl raw materials are stirred and mixed by a stirring blade, the stirring blade generally cannot move up and down. Therefore, when the stirring blade is working, it is easy for the stirring position to be not uniform and comprehensive. In addition, a scraper plate is generally provided to scrape the benomyl remaining on the inner wall of the kettle body. However, the scraper plate generates rotational friction with the inner wall of the kettle body for a long time. Not only is the scraper plate easy to wear, but the inner wall of the kettle body is also easy to be damaged due to long-term wear, which seriously affects the service life of the kettle body.

[0014] The utility model provides a synthesis kettle for producing benomyl, which has the following beneficial effects:

[0015] 1.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a synthesis kettle for benomyl production, comprising a kettle body 1 and a feed valve 2, a driving motor 4 is fixed at the middle of the upper end of the kettle body 1, a driving shaft 5 is connected to the power end of the driving motor 4, the driving shaft 5 rotates downward and penetrates into the kettle body 1, and an upper mounting plate 6 is fixed to the lower end of the driving shaft 5, a lower mounting plate 7 is provided below the upper mounting plate 6, and a first telescopic sleeve 8 is connected between the lower mounting plate 7 and the upper mounting plate 6, a shaft tube 9 is fixed to the lower end of the lower mounting plate 7, and a plurality of first stirring blades 10 are fixed on both sides of the shaft tube 9, and the first telescopic sleeve 8 is provided with a plurality of first stirring blades 10. A driving assembly is provided, which includes a rotating motor 17, a semicircular impact block 19, a semicircular protrusion 20 and two spring telescopic rods 16. The rotating motor 17 is fixed to the lower end of the upper mounting plate 6, and the power end of the rotating motor 17 is connected to a rotating shaft. Two semicircular impact blocks 19 are provided, and the semicircular impact blocks 19 are connected to the upper and lower parts of the rotating shaft. The semicircular protrusion 20 is fixed to the upper end of the lower mounting plate 7, and the semicircular protrusion 20 corresponds to the semicircular impact block 19. A battery is installed at the lower end of the upper mounting plate 6, and the spring telescopic rod 16 is connected between the upper mounting plate 6 and the lower mounting plate 7.

[0025] The driving motor 4 drives the driving shaft 5, the upper mounting plate 6, the first telescopic sleeve 8, the driving assembly, the lower mounting plate 7, the shaft tube 9 and the first stirring blade 10 to rotate, and the first stirring blade 10 will stir and mix the benomyl raw material. Under the premise that the storage battery in the first telescopic sleeve 8 is set in series with the rotating motor 17, and the rotating motor 17 is started, the rotating motor 17 drives the semicircular impact block 19 to continuously impact the semicircular projection 20, and the semicircular projection 20 will drive the lower mounting plate 7 to stretch the spring telescopic rod 16 downward, and the elasticity of the spring telescopic rod 16 will drive the lower mounting plate 7 and the semicircular projection 20 to move upward, so the semicircular impact block 19 continuously impacts the semicircular projection 20, and reciprocates in this way, so that the shaft tube 9 and the first stirring blade 10 can be continuously driven to reciprocate up and down by the up and down movement of the lower mounting plate 7. Therefore, the first stirring blade 10 will also move up and down when rotating and stirring, which is conducive to more uniform and comprehensive stirring and mixing of the benomyl raw material in the kettle body 1, thereby effectively ensuring the efficiency of the mixed synthesis of benomyl.

[0026] In this embodiment, a pressure plate 11 is fixed to the lower end of the shaft tube 9, and a support plate 12 is provided below the pressure plate 11. A second telescopic sleeve 13 and two spring pressure rods 18 are connected between the support plate 12 and the pressure plate 11. The spring pressure rods 18 are located in the second telescopic sleeve 13. A support shaft 14 is rotatably connected between the lower end of the support plate 12 and the bottom end of the kettle body 1. A second stirring blade 15 fixed to the lower end of the support plate 12 is provided on both sides of the support shaft 14.

[0027] When the shaft tube 9 moves up and down, the shaft tube 9 will push the pressure plate 11 downward, so the pressure plate 11 will compress the second telescopic sleeve 13 and the spring pressure rod 18, and combined with the elasticity of the spring pressure rod 18, it is beneficial to better ensure the normal up and down movement of the shaft tube 9 and the first stirring blade 10, and when the shaft tube 9 rotates, it will drive the first telescopic sleeve 8, the spring pressure rod 18, the support plate 12 and the second stirring blade 15 to rotate. Since the support shaft 14 is supported on the lower end of the support plate 12, the second stirring blade 15 is set to be close to the inner bottom end of the kettle body 1. Under the premise of preventing unnecessary friction between the second stirring blade 15 and the inner bottom end of the kettle body 1, the second stirring blade 15 can be prevented from generating unnecessary friction with the inner bottom end of the kettle body 1. Therefore, when the second stirring blade 15 rotates, the benomyl raw material deposited at the inner bottom end of the kettle body 1 can be stirred up to avoid the situation that the benomyl raw material at the inner bottom end of the kettle body 1 cannot be mixed, thereby better ensuring the comprehensiveness of the synthesis of benomyl.

[0028] In this embodiment, scraper plates 26 are provided at the left and right ends of the inner wall of the kettle body 1, and push rods 23 are fixed on the inner sides of the scraper plates 26. A pushing assembly is provided in the shaft tube 9, and the pushing assembly includes an electric cylinder 21, a pushing block 22, a pushing plate 24 and a return spring 25. The electric cylinder 21 is fixed to the inner bottom end of the shaft tube 9, and a battery is installed in the shaft tube 9. The pushing block 22 is connected to the power end of the electric cylinder 21, and the left and right sides of the pushing block 22 are inclined. The push rods 23 are rotated to penetrate into the shaft tube 9, and the pushing block 22 extends between the two push rods 23. The push plates 24 are provided with two pieces and are fixed one by one to the upper ends of the two push rods 23. The return springs 25 are connected between the outer side of the push plate 24 and the inner wall of the shaft tube 9.

[0029] When the benomyl is stirred and mixed by the first stirring blade 10, the scraper plate 26 is not in contact with the inner wall of the kettle body 1 at this time. Therefore, when the shaft tube 9 rotates and drives the push rod 23 and the scraper plate 26 to rotate, the problem of the scraper plate 26 being damaged by long-term friction with the inner wall of the kettle body 1 is effectively solved. When the benomyl on the inner wall of the kettle body 1 needs to be scraped off, the battery in the shaft tube 9 is set to be connected in series with the electric cylinder 21. When the electric cylinder 21 works and extends, the electric cylinder 21 will drive the push block 22 to move upward. At this time, the push block 22 will push the two push rods 23 outward at the same time, and then the push plate 24 will compress the return spring 25 until the push rod 23 drives the scraper plate 26 to contact the inner wall of the kettle body 1. Therefore, the push rod 23 and the scraper plate 26 are pushed outward by the work of the pushing assembly, so that the scraper plate 26 can be conveniently driven to contact the inner wall of the kettle body 1. Therefore, the benomyl on the inner wall of the kettle body 1 can be conveniently scraped and removed by the scraper plate 26.

[0030] In this embodiment, the feed valve 2 is connected to the upper end of the kettle body 1, and the lower end of the kettle body 1 is connected to the discharge valve 3.

[0031] By providing the feed valve 2 , various benomyl raw materials can be added into the kettle body 1 through the feed valve 2 , and the synthesized benomyl can be conveniently discharged from the kettle body 1 by opening the discharge valve 3 .

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
