DETAILED DESCRIPTION

[0026] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0027] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.

[0028] See also Figure 1-3 A chemical reaction tank in this embodiment includes a tank body 100, a cavity 210 with an upper opening is provided in the tank body 100, a tank cover 110 is provided at the upper opening of the tank body 100, a rotatable stirring shaft 220 is provided in the cavity 210, and a plurality of stirring rods 230 are evenly provided on the outer surface of the stirring shaft 220;

[0029] A cleaning assembly is provided on the outer surface of the stirring shaft 220, and the cleaning assembly includes a relatively arranged mounting box 240, a mounting cavity 241 is provided in the mounting box 240, a connecting rod 250 with one end extending out of the mounting box 240 is provided in the mounting cavity 241, a scraper 251 is provided at the extended end of the connecting rod 250 for scraping the side wall of the cavity 210, and a telescopic assembly is provided in the mounting cavity 241, and the telescopic assembly is used to synchronously control the telescopic extension of the connecting rod 250 in the corresponding mounting cavity 241.

[0030] In this embodiment, a lower flange is provided at the upper opening of the cavity 210, and an upper flange is provided at the outer edge of the tank cover 110. The lower flange and the upper flange are matched by bolts, thereby realizing the disassembly and assembly of the tank cover 110 at the upper end of the tank body 100.

[0031] The upper side of the tank cover 110 is provided with a feed port 140, and the lower end of the cavity 210 is provided with a discharge port 160. During the chemical reaction, chemical raw materials are put into the cavity 210 through the feed port 140. When the chemical raw materials are rotated by the stirring shaft 220 and the stirring rod 230 is driven to rotate and stir evenly, the chemical raw materials after the reaction in the cavity 210 are discharged from the tank body 100 through the discharge port 160.

[0032] Among them, by setting the connecting rod 250 and the scraper 251, after the reacted chemical raw materials are discharged from the tank body 100, the rotation of the stirring shaft 220 can drive the connecting rod 250 to rotate, so that the connecting rod 250 can drive the scraper 251 to clean and scrape the side wall of the cavity 210;

[0033] The lower end of the tank body 100 is provided with a support leg 150, which is fixed to the ground by bolts, thereby better supporting the chemical reaction tank so that it can be used in a chemical workshop;

[0034] The bottom end of the tank body 100 is provided with a motor 170, which is connected to the lower end of the stirring shaft 220. The motor 170 is used to drive the stirring shaft 220, thereby driving the stirring rod 230 to stir.

[0035] A support frame 350 for mounting the stirring shaft 220 is provided in the cavity 210 and at the upper end thereof. The upper end of the stirring shaft 220 is arranged through the support frame 350. A bearing is provided at the position where the stirring shaft 220 passes through the support frame 350. The stirring shaft 220 is rotatably mounted on the support frame 350 through the bearing, thereby making the rotation of the stirring shaft 220 more stable.

[0036] In this embodiment, the installation box 240 is relatively fixedly installed on the outer surface of the stirring shaft 220 by welding, wherein the outer side surface of the installation cavity 241 is provided with an opening, and the opening setting can facilitate the installation of the connecting rod 250 and the telescopic assembly in the installation cavity 241, and the opening is fixedly installed with a mounting cover plate 280 by bolts, so that the installation cavity 241 is sealed to prevent the reaction material in the tank body 100 from entering the installation cavity 241;

[0037] Among them, through the setting of the telescopic assembly, when the telescopic assembly makes the relative connecting rod 250 in a retracted state, a certain distance is left between the scraper 251 and the side wall of the cavity 210, that is, when the stirring shaft 220 rotates for stirring, the scraper 251 and the side wall of the cavity 210 are scraped, thereby avoiding the wear of the scraper 251;

[0038] When the telescopic assembly makes the relative connecting rod 250 in an extended state, the scraper 251 can contact the side wall of the cavity 210, that is, when the cavity 210 is cleaned, the rotation of the stirring shaft 220 can drive the scraper 251 to scrape and clean the side wall of the cavity 210.

[0039] See also Figure 3-5 In this embodiment, the telescopic assembly includes a moving block 270 located in the corresponding installation cavity 241 and moving. The connecting rod 250 is connected to one side of the moving block 270. A spring 290 is sleeved on the connecting rod 250. The spring 290 is used to drive the moving block 270 to move toward the stirring shaft 220. A push rod 252 is provided on the other side of the moving block 270.

[0040] A shaft cavity 360 with an open upper end is provided in the stirring shaft 220, and a rotatable shaft 320 is provided in the shaft cavity 360. The upper end of the shaft 320 extends out of the shaft cavity 360, and a groove 310 is provided on the outer side surface of the shaft 320 and at the lower end thereof. The push rod 252 extends into the corresponding groove 310, and a guide slope 311 is provided on the side wall of the groove 310. The rotation of the shaft 320 is used to drive the push rod 252 to slide out of the groove 310 along the corresponding guide slope 311.

[0041] In this embodiment, the moving block 270 is rectangular, and the side wall of the moving block 270 can slide and fit with the side wall of the installation cavity 241, so that the moving block 270 can slide smoothly in the installation cavity 241;

[0042] One end of the spring 290 abuts against one side surface of the moving block 270, and the other end abuts against the installation cover plate 280, so that the spring 290 is installed in the installation cavity 241. At the same time, the spring 290 can drive the moving block 270 to move toward the stirring shaft 220, drive the connecting rod 250 to move the scraper 251 away from the side wall of the cavity 210, and drive the ejector rod 252 to extend into the groove 310.

[0043] In this embodiment, when the push rod 252 extends into the groove 310, the shaft 320 is in the initial position. At this time, the telescopic assembly is in a retracted state, that is, the connecting rod 250 drives the scraper 251 so that it does not contact the side wall of the cavity 210; at this time, when the shaft 320 is rotated, the groove 310 at the lower end of the shaft 320 is rotated, so that the guide slope 311 on the side wall of the groove 310 squeezes the push rod 252, so that the push rod 252 slides along the guide slope 311. The movable block 270 drives the connecting rod 250 to move toward the side wall of the cavity 210, so that the scraper 251 contacts the side wall of the cavity 210; at this time, the rotating shaft 320 is rotated in the opposite direction to reset the rotating shaft 320. At this time, the top rod 252 slides into the groove 310 along the guide slope 311 under the action of the spring 290, so that the movable block 270 drives the connecting rod 250 to move toward the direction of the stirring shaft 220, so that the scraper 251 is separated from the side wall of the cavity 210.

[0044] See also Figure 2-6 In this embodiment, a limiting ring 361 is provided at the upper opening of the shaft cavity 360, and an annular groove is provided on the outer side of the rotating shaft 320 and at the upper end. The annular groove is arranged along the circumference of the rotating shaft 320, and the limiting ring 361 extends into the annular groove.

[0045] In this embodiment, the limiting ring 361 is connected to the upper opening of the shaft cavity 360 by means of a thread. Due to the setting of the annular groove, the limiting ring 361 installed at the upper opening of the shaft cavity 360 can extend into the annular groove and abut against the bottom side wall of the annular groove, thereby realizing the stable rotation of the rotating shaft 320 in the shaft cavity 360.

[0046] A rotating disk 330 is provided at the upper end of the rotating shaft 320, and the rotating disk 330 is rotated to drive the rotating shaft 320 to rotate, so as to facilitate the operator to perform the rotating operation of the rotating shaft 320;

[0047] Combination Figure 6 As shown, in this embodiment, a chuck 340 is provided on the outer side surface of the stirring shaft 220 and at the upper end portion, and a first positioning hole 410 and a second positioning hole 411 are provided on the chuck 340. A positioning bolt 420 is threadedly connected to the turntable 330. The positioning bolt 420 extends into the first positioning hole 410 to keep the push rod 252 in the groove 310, and the positioning bolt 420 extends into the second positioning hole 411 to keep the push rod 252 in the groove 310.

[0048] In this embodiment, when the rotating disk 330 and the chuck 340 are fixed by the positioning bolts 420, the rotating shaft 320 and the stirring shaft 220 are relatively fixed, so as to avoid the rotating shaft 320 and the stirring shaft 220 rotating relative to each other when the stirring shaft 220 rotates, causing the scraper 251 to switch between two states, which affects the actual use;

[0049] Among them, when the positioning bolt 420 extends into the first positioning hole 410, the scraper 251 does not contact the side wall of the cavity 210, and during the stirring process, the scraper 251 will not scrape the side wall of the cavity 210. When the positioning bolt 420 extends into the second positioning hole 411, the scraper 251 contacts the side wall of the cavity 210, and during the cleaning process, the scraper 251 scrapes and cleans the side wall of the cavity 210.

[0050] Working principle: When the chemical reaction tank is stirring the chemical raw materials, the positioning bolt 420 is first extended into the first positioning hole 410 to separate the scraper 251 from the side wall of the cavity 210, so as to avoid the scraper 251 from scratching the side wall of the cavity 210 during the stirring process, thereby protecting the side wall of the cavity 210; when the side wall of the cavity 210 needs to be cleaned, the positioning bolt 420 is first switched to extend into the second positioning hole 411 to make the scraper 251 contact the side wall of the cavity 210, and then the stirring shaft 220 is driven to rotate so that the scraper 251 scrapes and cleans the side wall of the cavity 210.
