[0030] Reference Figure 1 and Figure 2 A chemical engineering mixing tank includes a tank body 100, a stirring mechanism 200, and a lifting mechanism 300. The tank body 100 is provided with a feed inlet 110 and a discharge outlet 120. The stirring mechanism 200 is located in the tank body 100 and includes a first driver 210 and a main shaft 220. The main shaft 220 extends longitudinally into the inner cavity of the tank body 100 and can move up and down relative to the tank body 100. The main shaft 220 is provided with a stirring element 230 located in the inner cavity of the tank body 100. The first driver 210 is drivenly connected to the main shaft 220 to drive the main shaft 220 to rotate. The lifting mechanism 300 is located in the tank body 100 and connected to the stirring mechanism 200. The lifting mechanism 300 can drive the stirring mechanism 200 to move up and down relative to the tank body 100.

[0031] Understandably, such as Figure 1 and Figure 2As shown, the lifting mechanism 300 is located on the upper side of the tank 100 and connected to the stirring mechanism 200. The main shaft 220 extends longitudinally into the inner cavity of the tank 100, and its upper end is connected to the first driver 210 for transmission. The stirring element 230 is located on the periphery of the main shaft 220 and in the inner cavity of the tank 100. In use, the material is fed into the inner cavity of the tank 100 through the feed inlet 110. The stirring mechanism 200 drives the main shaft 220 to rotate through the first driver 210, and the stirring element 230 on the main shaft 220 stirs the material in the inner cavity of the tank 100. By setting the lifting mechanism 300, the stirring mechanism 200 can be driven to move up and down when stirring the material, so that the stirring mechanism 200 can flexibly stir at different positions, expand the stirring range, and make the material more even and thorough to improve the stirring effect, which is conducive to improving production quality and efficiency.

[0032] In practical applications, the specific structures of the tank 100, the stirring mechanism 200, and the lifting mechanism 300 can be set according to actual usage needs. They will not be described in detail here, but will be explained in detail below.

[0033] In some embodiments, the lifting mechanism 300 includes a second driver 310, a threaded rod 320, a threaded sleeve 330, and a housing 340. The stirring mechanism 200 is connected to the housing 340, the housing 340 is connected to the threaded sleeve 330, the threaded sleeve 330 is threadedly engaged with the threaded rod 320, the second driver 310 is drivenly connected to the threaded rod 320, and is used to drive the threaded rod 320 to rotate. When the threaded rod 320 rotates, the threaded sleeve 330 moves along the threaded rod 320 and can drive the housing 340 to move up and down.

[0034] Understandably, such as Figure 1 , Figure 2 and Figure 3As shown, the threaded sleeve 330 and the threaded rod 320 are threadedly engaged to form a screw drive structure. The housing 340 is connected to the threaded sleeve 330, and the stirring mechanism 200 is connected to the housing 340. In use, the second driver 310 drives the threaded rod 320 to rotate. Utilizing the screw drive principle, the rotation of the threaded rod 320 is converted into the movement of the threaded sleeve 330. The movement of the threaded sleeve 330 drives the housing 340 to move up and down, thereby driving the stirring mechanism 200 to move up and down. Utilizing the self-locking property of the screw drive, the possibility of the stirring mechanism 200 becoming loose when moving up and down is reduced, improving the stability and reliability of the motion drive. In practical applications, in addition to screw drive, the lifting mechanism 300 can also drive the stirring mechanism 200 to move up and down through gear and rack drive. For example, the second driver 310 is connected to the gear drive to drive the gear to rotate. The gear meshes with the rack, causing the rack to move up and down. The stirring mechanism 200 is connected to the rack, thereby driving the stirring mechanism 200 to move up and down. Alternatively, the lifting mechanism 300 can also directly drive the stirring mechanism 200 to move up and down through the driver. The specific settings can be adjusted according to the actual needs of the application.

[0035] In some embodiments, the lifting mechanism 300 further includes a connecting rod 350, a threaded rod 320 is arranged laterally and has a first threaded section 321 and a second threaded section 322, the first threaded section 321 and the second threaded section 322 have opposite thread directions, two threaded sleeves 330 are provided and are threadedly engaged with the first threaded section 321 and the second threaded section 322 respectively, two connecting rods 350 are provided and are respectively provided with two threaded sleeves 330, one end of the connecting rod 350 is hinged to the threaded sleeve 330, and the other end of the connecting rod 350 is hinged to the housing 340.

[0036] Understandably, such as Figure 1 , Figure 2 and Figure 3As shown, the threaded rod 320 is arranged laterally in the left-right direction, and has a first threaded section 321 and a second threaded section 322 with opposite thread directions. Two threaded sleeves 330 are threadedly engaged with the first threaded section 321 and the second threaded section 322 respectively. Each threaded sleeve 330 is connected to the housing 340 through a connecting rod 350. The two ends of the connecting rod 350 are hinged to the threaded sleeve 330 and the housing 340 respectively. In operation, the second actuator 310 drives the threaded rod 320 to rotate. Since the first threaded section 321 and the second threaded section 322 have opposite thread directions, the two threaded sleeves 330 move in opposite directions. This causes the two threaded sleeves 330 to move closer or further apart relative to each other as the threaded rod 320 rotates. When the two threaded sleeves 330 move closer, the angle between the two connecting rods 350 decreases, increasing the distance from the housing 340 to the threaded rod 320. This causes the housing 340 to move downwards relative to the threaded rod 320, driving the stirring mechanism 200 downwards. Conversely, when the two threaded sleeves 330 move further apart, the angle between the two connecting rods 350 increases, decreasing the distance from the housing 340 to the threaded rod 320. This causes the housing 340 to move upwards relative to the threaded rod 320, driving the stirring mechanism 200 upwards. This structure reduces the load on the threads between the threaded rod 320 and the threaded sleeves 330, improving the stability and reliability of the movement. In practical applications, in addition to the above structure, the threaded rod 320 can also be set longitudinally in the up-down direction, and the housing 340 can be directly connected to the threaded sleeve 330. This allows the housing 340 to move up and down relative to the threaded rod 320. The specific configuration can be adjusted according to actual usage requirements.

[0037] In some embodiments, the lifting mechanism 300 further includes a connecting seat 360, which is fixedly connected to the tank 100, and the housing 340 is slidably connected to the connecting seat 360 and can move up and down relative to the connecting seat 360.

[0038] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, by setting the chassis 340 to slide and connect to the connector 360, and allowing the chassis 340 to move up and down relative to the connector 360, the up and down movement of the chassis 340 can be guided and limited, which helps to improve the stability of the movement and facilitates use. In practical applications, the specific structure of the connector 360 can be set according to the actual needs of use.

[0039] In some embodiments, the connecting seat 360 is provided with a slide rod 361, which extends longitudinally, and the side of the chassis 340 is provided with a sliding sleeve 341, which is slidably sleeved on the slide rod 361.

[0040] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, the slide rod 361 extends vertically, and the sliding sleeve 341 is located on the side of the chassis 340 and slidably sleeved on the slide rod 361. This achieves a sliding fit between the chassis 340 and the connecting seat 360. Its structure is simple and easy to use. In practical applications, in addition to the above structure, the sliding fit between the chassis 340 and the connecting seat 360 can also be achieved through a slide rail slider or a slide groove slider structure, which can be set according to actual usage needs.

[0041] In some embodiments, two connectors 360 are provided and are respectively located on the left and right sides of the chassis 340. It is understood that, as Figure 1 , Figure 2 and Figure 3 As shown, the two connectors 360 are located on the left and right sides of the chassis 340 respectively and slide in engagement with the chassis 340, thereby further improving the stability and reliability of the chassis 340's vertical movement and facilitating its use. In practical applications, only one connector 360 can be used, depending on the actual usage requirements.

[0042] In some embodiments, the chassis 340 has a receiving cavity 342 with a side opening, and the first driver 210 is disposed in the receiving cavity 342. It is understood that, as Figure 1 , Figure 2 and Figure 3 As shown, the housing cavity 342 of the chassis 340 has a front opening, and the first driver 210 is disposed in the housing cavity 342 of the chassis 340. This allows the chassis 340 to protect the first driver 210, reducing the possibility of contamination and facilitating its use. In practical applications, the specific structure of the chassis 340 can be varied according to actual usage requirements.

[0043] In some embodiments, the main shaft 220 is provided with multiple sets of stirring groups, each set of stirring groups including multiple stirring elements 230. The multiple stirring elements 230 in the same set of stirring groups are distributed at intervals along the rotation axis of the main shaft 220, and the multiple sets of stirring groups are evenly distributed at intervals around the rotation axis of the main shaft 220.

[0044] Understandably, such as Figure 2 and Figure 4 As shown, the main shaft 220 is equipped with three sets of stirring groups. Each stirring group includes three stirring elements 230 spaced apart in the vertical direction. The three stirring groups are evenly distributed around the rotation axis of the main shaft 220, thereby achieving a better stirring effect and facilitating use. In practical applications, there can also be two or four stirring groups, and each stirring group can include two, four, or more stirring elements 230, depending on the actual needs.

[0045] In some embodiments, a scraper 240 is connected to the end of the agitator 230 away from the main shaft 220, and the scraper 240 can contact the inner wall of the tank 100. It is understood that, as Figure 1 , Figure 2 and Figure 4 As shown, by providing a scraper 240 at the end of the agitator 230, during use, the agitator 230 drives the scraper 240 to rotate. The scraper 240 contacts the inner wall of the tank 100, effectively scraping away material adhering to the inner wall, preventing material residue, reducing waste, lowering subsequent cleaning difficulty, and improving production efficiency and equipment lifespan. In practical applications, the specific structure of the scraper 240 can be set according to actual usage needs.

[0046] In some embodiments, a plurality of support feet 130 are provided on the outer side of the tank body 100. The plurality of support feet 130 are distributed at intervals along the circumference of the tank body 100 and can suspend the lower side of the tank body 100. The discharge port 120 is provided on the lower side of the tank body 100.

[0047] Understandably, such as Figure 1 As shown, multiple support feet 130 are distributed at intervals along the circumference of the tank body 100, allowing the lower side of the tank body 100 to be suspended in the air. The discharge port 120 is located on the lower side of the tank body 100, which facilitates the discharge of material inside the tank body 100 through the discharge port 120. The structure is simple and easy to use. In practical applications, the specific number of support feet 130 can be set according to actual usage needs.
