DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Referring to the accompanying drawings: This pneumatic magnetic heat-insulating stirring tank includes a tank body 2 and a stirring device 3. The tank body 2 includes an outer layer 21 and an inner layer 22. The stirring device 3 includes a pneumatic magnetic stirrer 31 and a stirring paddle 32. The pneumatic magnetic stirrer 31 is arranged at the lower end of the inner layer 22. One end of the stirring paddle 32 is connected to the pneumatic magnetic stirrer 31 and the other end extends into the inner layer 22. The stirring paddle 32 includes a stirring connecting rod 321, a plurality of stirring blades 322, and a plurality of scraping blades 323. The stirring connecting rod 321 has an assembly front side 3211 and an assembly back side 3212. The assembly front side 3211 is provided with a stirring blade 322, and a stirring blade 323 is provided with a stirring blade 323. A plurality of positioning grooves 32111 for quickly defining each scraper blade 323 at a corresponding position are provided on 211, a plurality of installation grooves 32121 matching the positions of the positioning grooves 32111 are provided on the assembly back side 3212, a locking unit 4 which can be stretched and extended is provided in the installation groove 32121, a locking node 5 which can be combined with the locking unit 4 when the locking unit 4 rebounds to a locked state is provided on the scraper blade 323, and a through hole 321111 is provided on the positioning groove 32111 on the stirring connecting rod 321 to allow part of the locking unit 4 to pass through and extend into the positioning groove 32111. The principle of the utility model is that the installation position of the scraper 323 on the stirring connecting rod 321 is limited by the positioning groove 32111, and the tool-free and parts-free operation mode of assembling the scraper 323 and the stirring connecting rod 321 can be realized through the locking unit 4 and the locking node 5, that is, when unlocking, it is only necessary to apply a stretching force to the locking unit 4 to disengage the locking node 5, and when locking, the locking can be achieved by releasing the stretching of the locking unit 4 (that is, the locking unit 4 interferes with the path of the assembly direction of the scraper 323), which is suitable for quick assembly and convenient assembly, which facilitates the subsequent replacement of the scraper 323 and eliminates the tediousness of using bolts and the like.

[0021] The stirring connecting rod 321 is in a U-shaped configuration and is used to set the stirring blade 322 and the scraper blade 323. The stirring blades 322 are grouped in pairs, and one end is set on the vertical section of the stirring connecting rod 321, and the other end is provided with a shaft sleeve 6 connected to both at the same time. The shaft sleeve 6 is set on the rotating shaft 311 of the pneumatic magnetic stirrer 31. Such a setting enables the stirring connecting rod 321 to provide a sufficient assembly area, that is, a plurality of scrapers 323 can be set, and the installation position of the scraper blade 323 is close to the inner wall of the inner layer 22, so that there is no need to set a large The scraper blade 323 has a certain length (the longer the length, the weaker the structural strength), because the scraper blade 323 needs to perform a stirring action while performing a wall scraping and cleaning action, and the stirring blade 322 can not only be used to stir the material, but also increase the structural strength of the stirring connecting rod 321, so that the stirring connecting rod 321 is not easily damaged during stirring, and can also act as a connecting component to connect the shaft sleeve 6. The shaft sleeve 6 enables the stirring device 3 to be set on the rotating shaft 311 of the pneumatic magnetic stirrer 31 so as to rotate under the drive of the pneumatic magnetic stirrer 31.

[0022] The stirring blade 322 is inclined, and the stirring blade 322 on one side of the sleeve 6 is inclined toward the direction close to the assembly front side 3211, and the stirring blade 322 on the other side is inclined toward the direction close to the assembly back side 3212. Such an arrangement can be.

[0023] The scraper 323 includes a positioning block 3231 and a blade 3232. The positioning block 3231 is arranged in the positioning groove 32111 and a locking node 5 is formed on its lower end surface. The blade 3232 is arranged on the outer wall of the positioning block 3231. The positioning block 3231 is placed in the positioning groove 32111 and is used to set the locking node 5 to realize the combination with the locking unit 4 so that the scraper 323 is confined in the positioning groove 32111 to realize the connection between the scraper 323 and the stirring connecting rod 321. The blade 3232 is located outside the positioning groove 32111 to facilitate the wall scraping and stirring actions.

[0024] The positioning groove 32111 is provided with limiting grooves 321112 on the stirring connecting rod 321, which are symmetrically distributed on both sides of the positioning groove 32111 and communicated with the positioning groove 32111. The positioning block 3231 is provided with limiting extension blocks 32311 which are symmetrically distributed on both sides and inserted into the corresponding limiting grooves 321112. Such a setting limits the direction in which the positioning block 3231 enters the positioning groove 32111, and can only enter from the side, that is, forming a constraint in the front and rear directions, so that after being locked by the locking unit 4, the locking unit 4 exists on the path of the assembly direction of the positioning block 3231, so that the blade 3232 can be stably maintained in the positioning groove 32111.

[0025] The outer edge configuration of the blade 3232 near one end of the inner wall of the inner layer 22 matches the configuration displayed at the corresponding position of the inner wall of the inner layer 22. This setting takes into account that the inner layer 22 of the tank body 2 has two configurations, namely, straight line and arc. In this way, the hanging surface of the blade 3232 (near one end of the inner wall of the inner layer 22) can fully contact the inner wall of the inner layer 22, thereby achieving a good cleaning effect.

[0026] The locking node 5 has at least two, including an enclosing wall 51 arranged on the lower end surface of the positioning block 3231, and a rebound space 52 defined within the enclosing wall 51 and allowing the locking unit 4 to rebound to the locked state. The enclosing wall 51 abuts against part of the locking unit 4 in the direction opposite to the locking direction. When the locking unit 4 reaches the rebound space 52 of the locking node 5, the locking unit 4 is freely released from the restrained state stretched by the user, that is, it is restored to the locked state under its rebound performance. The enclosing wall 51 blocks the locking unit 4 that has restored the locked state, abuts against the locking unit 4 in the direction opposite to the locking direction, thereby preventing the locking unit 4 from returning along the original path, and completing the locking state of the stirring connecting rod 321 and the scraper 323 in the final assembly position. In this embodiment, the locking node 5 is a socket, the hole wall of which forms the enclosing wall 51, and the socket allows the space in which the locking unit 4 is placed to form a rebound space 52.

[0027] The locking unit 4 includes a mounting block 41, a locking protrusion 42, and a spring 43. The mounting block 41 is arranged in the mounting groove 32121. The locking protrusion 42 is arranged on the upper end surface of the mounting block 41 and passes through the through hole 321111 to be combined with the locking node 5, and the number and position of the spring 43 match the locking node 5. The spring 43 is sleeved on the locking protrusion 42 arranged in the mounting groove 32121, one end of the spring 43 is arranged on the inner top surface of the mounting groove 32121, and the other end is arranged on the upper end surface of the mounting block 41. The mounting block 41 is placed in the mounting groove 32121 and is used to set the locking protrusion 42. The mounting block 41 provides a large gripping area, which is convenient for the user to grip after the mounting block 41 is partially separated from the mounting groove 32121, so as to provide a tensile force to the locking unit 4. The locking protrusion 42 passes through the through hole 321111 and combines with the locking node 5 and remains on the path of the assembly direction of the positioning block 3231, thereby locking the scraper 323. The spring 43 can automatically reset the locking unit 4 to the locked state after the user releases the control of the locking unit 4, and also enables the locking unit 4 to be stably maintained in the mounting groove 32121 without being affected by stirring. In this embodiment, the locking protrusion 42 is a cylindrical plug rod matching the configuration of the locking node 5.
