[0053] Referring to Figures 1 to 13 , this application provides a mixing tank, including: a tank body 1, a stirring assembly, a driving assembly, and a clamping mechanism.

[0054] Specifically, a fixed cover 101 and a movable cover 102 are respectively arranged at the top of the tank body 1, and the movable cover 102 is detachably installed on the fixed cover 101, and the movable cover 102 has an upper side and a lower side opposite to each other; among them, the movable cover 102 and the fixed cover 101 are preferably connected by a hinged manner. Specifically, a first hinge cylinder is arranged on one side of the top of the movable cover 102 close to the fixed cover 101, and second hinge cylinders are arranged on both sides of the top of the fixed cover 101 where the first hinge cylinder is located. A hinge rod is installed in the first hinge cylinder and the second hinge cylinder, so that the movable cover 102 is hingedly installed on the fixed cover 101, and the opening or closing of the tank body 1 can be realized through the movable cover 102.

[0055] The stirring assembly includes a first rotating shaft 2 and a second rotating shaft 3. The first rotating shaft 2 is rotatably arranged on the fixed cover 101, and the second rotating shaft 3 is arranged at one end of the first rotating shaft 2 below the fixed cover 101 for stirring the materials inside the tank body 1; among them, at least two groups of stirring blades 303 are arranged on the second rotating shaft 3, and the stirring blades 303 are detachably arranged on the second rotating shaft 3. In an actual application, preferably two groups of stirring blades 303 are arranged on the second rotating shaft 3, one of the stirring blades 303 is arranged at the bottom end of the second rotating shaft 3, and the other stirring blade 303 is arranged at the one-third position from the top end to the bottom end of the second rotating shaft 3 to realize more uniform stirring of the materials in the tank body 1.

[0056] The driving assembly is arranged above the fixed cover 101. One end of the second rotating shaft 3 above the fixed cover 101 is connected to the output end of the driving assembly, which is used to provide power for the stirring assembly. Among them, the driving assembly includes a driving motor 6 and a driving arm 601. A support frame 602 is arranged on the top of the fixed cover 101. The driving motor 6 is installed on the support frame 602. One end of the driving arm 601 is connected to the output shaft of the driving motor 6, and the other end of the driving arm 601 is connected to the top end of the first rotating shaft 2. In an actual application, the driving arm 601 is preferably a square frame structure with an opening at the bottom, and both ends of the opening of the square frame structure are fixedly connected to the first rotating shaft 2, and the middle of the top of the square frame structure is fixedly connected to the output end of the driving motor 6, so that the power can be transmitted from the driving motor 6 to the first rotating shaft 2.

[0057] The clamping mechanism is arranged between the first rotating shaft 2 and the second rotating shaft 3. The second rotating shaft 3 rotates synchronously or relatively with the first rotating shaft 2 through the clamping mechanism.

[0058] Thus, the mixing tank sets the stirring shaft as the first rotating shaft 2 and the second rotating shaft 3. The first rotating shaft 2 and the second rotating shaft 3 can achieve synchronous rotation and relative rotation through the clamping mechanism. When the material resistance received by the second rotating shaft 3 is large, the first rotating shaft 2 can rotate relative to the second rotating shaft 3, so that at the initial stage of starting the mixing tank, through the relative rotation of the first rotating shaft 2 and the second rotating shaft 3, the problem of excessive self-heating of the driving assembly caused by large material resistance can be solved, and to a certain extent, the driving assembly can be protected and its service life can be extended. At the same time, through the relative rotation of the second rotating shaft 3 and the first rotating shaft 2, the relative stirring speed between the stirring blades 303 of the second rotating shaft 3 and the material can be reduced, and the problem of serious material splashing during the material stirring process can be solved. During the subsequent operation of the mixing tank, the synchronous rotation of the second rotating shaft 3 and the first rotating shaft 2 can fully stir the material and realize the mixing of the material.

[0059] In a specific embodiment, the clamping mechanism includes a receiving cavity 201, a guiding member 202, an elastic member 203, a driving member 204 and a driven member 301. Specifically, the receiving cavity 201 is formed in the first rotating shaft 2. The receiving cavity 201 is preferably a cylindrical cavity. The guiding member 202 is disposed inside the receiving cavity 201. The guiding member 202 is preferably a rod-shaped structure. The driving member 204 is slidably disposed on the guiding member 202, and convex teeth 205 are uniformly arranged at the bottom of the driving member 204. Both side walls of the convex teeth 205 are arranged as inclined surfaces. The elastic member 203 is mounted on the guiding member 202 above the driving member 204. The elastic member 203 is preferably a spring, and the spring is preferably sleeved on the guiding rod. The top end of the second rotating shaft 3 extends into the receiving cavity 201. The driven member 301 is disposed at the top end of the second rotating shaft 3, and a clamping groove 302 corresponding to the convex teeth 205 is arranged at the top of the driven member 301. Both side walls of the clamping groove 302 are arranged as inclined surfaces corresponding to the convex teeth 205, so that the convex teeth 205 and the clamping groove 302 can interact through the inclined surfaces, enabling the convex teeth 205 to automatically disengage from the clamping groove 302 to realize the relative rotation between the two rotating shafts. When the convex teeth 205 are engaged with the clamping groove 302, the second rotating shaft 3 rotates synchronously with the first rotating shaft 2. When the convex teeth 205 are separated from the clamping groove 302, the second rotating shaft 3 rotates relative to the first rotating shaft 2.

[0060] It should be noted that the guiding members 202 are preferably arranged on the top wall of the receiving cavity 201 in a ring array manner. An anti-detachment ring plate is further arranged at the bottom end of the guiding member 202 to prevent the driving member 204 from detaching from the guiding member 202. A guiding disc 2041 is arranged on the surface of the driving member 204 opposite to the convex teeth 205, and guiding channels 2042 corresponding to the guiding members 202 are arranged in a ring array on the guiding disc 2041, so that the driving member 204 can move on the guiding member 202. A thrust ball bearing sleeved on the second rotating shaft 3 is arranged in the receiving cavity 201 to prevent the driven member 301 from directly contacting the bottom wall of the receiving cavity 201 and causing wear.

[0061] In a practical application, at the initial stage when the mixing tank is started, the relative speed difference between the stirring paddle 303 and the material is relatively large, and the resistance of the material on the stirring paddle 303 is relatively large. The convex teeth 205 and the clamping groove 302 interact through the inclined surfaces, causing the guiding disc 2041 to move along the guiding member 202 and compress the elastic member 203. The convex teeth 205 move out of the clamping groove 302, and the first rotating shaft 2 rotates relative to the second rotating shaft 3, which can reduce the load of the driving assembly to a certain extent, reduce its heat generation, and at the same time can also solve the serious splashing problem during the material stirring process. Subsequently, when the material in the tank body 1 flows, the resistance of the material on the stirring paddle 303 decreases, the relative speed difference between the stirring paddle 303 and the material becomes smaller, the convex teeth 205 enter the clamping groove 302 and engage with each other, and the second rotating shaft 3 rotates synchronously with the first rotating shaft 2 to stir the material.

[0062] As a preferred embodiment, the snap - connection mechanism further includes an adjustment component, and the adjustment component includes: an adjustment rod 4 and an adjustment sleeve 5. Among them, a pressing disc 401 is provided at the bottom end of the adjustment rod 4. The pressing disc 401 is located in the accommodation cavity 201. The pressing disc 401 is slidably arranged on a guiding member 202 above the elastic member 203. The adjustment rod 4 is arranged through the central axis of the second rotating shaft 3.

[0063] It should be noted that through - holes corresponding to the guiding member 202 are provided on the pressing disc 401, so that the pressing disc 401 can move along the guiding member 202 to adjust the compression degree of the elastic member 203.

[0064] The adjustment sleeve 5 is rotatably arranged at the top end of the first rotating shaft 2. When the adjustment sleeve 5 is rotated, the adjustment rod 4 can move up and down relative to the first rotating shaft 2.

[0065] It should be noted that a rotating seat 501 is provided at the bottom of the adjustment sleeve 5, and a supporting seat 206 is provided at the top of the first rotating shaft 2. The rotating seat 501 can rotate on the supporting seat 206, so that the adjustment sleeve 5 is rotatably connected to the first rotating shaft 2, and the position of the pressing disc 401 on the guiding member 202 is adjusted.

[0066] In a practical application, the adjustment rod 4 is arranged through the central axis of the adjustment sleeve 5. External threads are provided on the outer wall of the top end of the adjustment rod 4, and the adjustment sleeve 5 is an internally - threaded sleeve. Through the cooperation of the internally - threaded sleeve and the external threads, the adjustment rod 4 can move along the first rotating shaft 2 to adjust the position of the pressing disc 401 on the guiding member 202 and the compression degree of the elastic member 203, thereby adjusting the difficulty of the convex teeth 205 disengaging from the card slots 302, so that a certain balance is maintained between the synchronous rotation and relative rotation of the first rotating shaft 2 and the second rotating shaft 3, and it can be adjusted according to the actual situation to avoid excessive heat generation of the driving component at the initial stage of the mixing tank startup and serious splashing of the materials in the tank body 1.

[0067] In a specific embodiment, at least two support beams 103 are provided at the bottom of the fixed cover 101, and a filter screen 7 is detachably installed between the support beams 103. As a preferred embodiment, at least two groups of hanging handles 701 are symmetrically arranged on both sides of the filter screen 7, and limiting grooves 104 corresponding to the hanging handles 701 are provided on the support beams 103. In a practical application, the support beams 103 are preferably two and are symmetrically arranged at the bottom of the fixed cover 101. One end of the support beam 103 far from the fixed cover 101 is fixedly connected to the wall body of the tank body 1. The hanging handles 701 are preferably two groups and each group includes two. While positioning the filter screen 7 through the cooperation of the hanging handles 701 and the limiting grooves 104, the filter screen 7 can be detached from the support beams 103, which is convenient for subsequent maintenance and cleaning of the filter screen 7.

[0068] When adding materials, the materials can be added into the tank body 1 through the filter screen 7. In this way, not only can the impurities in the materials be filtered, but also the large pieces of materials can be broken when the materials collide with the filter screen 7, improving the quality of material addition. At the same time, the filter screen 7 has a certain buffering effect and can also reduce the splashing problem caused when the materials directly fall into the tank body 1.

[0069] In a specific embodiment, a mixing chamber 105 is arranged inside the tank body 1. The side wall of the mixing chamber 105 has eight surfaces, and the bottom wall of the mixing chamber 105 is arranged as a conical structure sunken from the centers of the bottom walls of the eight side surfaces; with this kind of arrangement, the dead corners in the mixing chamber 105 can be reduced, the degree of thorough mixing of the materials and the degree of thorough discharging in the subsequent process can be improved, and the cleaning difficulty of the subsequent mixing chamber 105 can be reduced.

[0070] As a preferred mode, a discharge port 106 is opened at the center of the conical structure, and a control valve can be installed on the discharge port 106. Through the adjustment of the control valve, the stirred materials can be discharged through the control valve.
