Detailed Description of the Preferred Embodiments

[0037] The present utility model will be described below in conjunction with specific embodiments.

[0038] Embodiment 1, as shown in Figure 1 and Figure 2 A new type of experimental kettle device includes a frame 1, a main body of the experimental kettle 2, a stirring mechanism 3, and a lifting drive mechanism 4 installed on the frame 1. A lifting movable frame 5 is installed above the frame 1, and the lifting drive mechanism 4 is drivingly connected to the lifting movable frame 5.

[0039] Among them, as shown in Figure 1 and Figure 2 the main body of the experimental kettle 2 includes a kettle body 21 and a kettle cover 22 that moves up and down synchronously with the lifting movable frame 5. A stirring chamber 211 with an upward opening is formed inside the kettle body 21.

[0040] Furthermore, as shown in Figure 1 and Figure 2 the stirring mechanism 3 moves up and down synchronously with the lifting movable frame 5, and the stirring mechanism 3 includes a stirring drive motor 31 and a stirring rotating shaft 32 driven by the stirring drive motor 31.

[0041] Furthermore, a plurality of stirring rod groups 33 are arranged at intervals from top to bottom on the stirring rotating shaft 32. Each stirring rod group 33 includes two transverse stirring rods 331 that are aligned radially with respect to the stirring rotating shaft 32. The inner ends of the transverse stirring rods 331 are respectively fixedly connected to the stirring device. The stirring mechanism 3 further includes two spiral ribbon blades 34. The two spiral ribbon blades 34 are symmetrically arranged on both sides of the stirring rotating shaft 32. Each spiral ribbon blade 34 is a metal part. The outer ends of the transverse stirring rods 331 are respectively welded to the corresponding spiral ribbon blade 34. It should be noted that the transverse stirring rods 331 and the spiral ribbon blades 34 in the first embodiment are made of stainless steel parts.

[0042] In addition, the frame 1 is provided with a flip sleeve 6 that can flip. An upwardly open sleeve accommodation cavity 61 is formed inside the flip sleeve 6. The kettle body 21 is fixedly installed in the sleeve accommodation cavity 61 of the flip sleeve 6.

[0043] In addition, a positioning mechanism is installed between the kettle body 21 and the kettle lid 22.

[0044] It should be pointed out that the new experimental kettle device in the first embodiment is equipped with a PLC controller (not shown in the figure). The PLC controller is electrically connected to the stirring drive motor 31 and the lifting drive mechanism 4 respectively. During operation, the PLC controller controls the actions of the stirring drive motor 31 and the lifting drive mechanism 4 respectively.

[0045] The novel experimental kettle device of the first embodiment will be described below in combination with the specific working process. Specifically: before adding materials into the stirring chamber 211 of the kettle body 21, the lifting drive mechanism 4 drives the lifting movable frame 5 to move upward, causing the kettle lid 22 to open upward and the stirring mechanism 3 to retreat from the stirring chamber 211 of the kettle body 21; after the lifting drive mechanism 4 drives the lifting movable frame 5 to move upward in place, materials are added into the stirring chamber 211 of the kettle body 21; after the materials are added into the stirring chamber 211 of the kettle body 21, the lifting drive mechanism 4 acts in the reverse direction and drives the lifting movable frame 5 to move downward. The downward-moving movable lifting frame drives the stirring mechanism 3 and the kettle lid 22 to move downward synchronously, and finally causes the kettle lid 22 to close on the upper end of the kettle body 21, and the lower end of the stirring shaft 32 of the stirring mechanism 3, each stirring rod group 33, and each spiral blade 34 respectively extend into the stirring chamber 211; after the kettle lid 22 is closed, the PLC controller controls the stirring drive motor 31 to start, and the stirring drive motor 31 drives the stirring shaft 32 to rotate. The rotating stirring shaft 32 drives each stirring rod group 33 and the spiral blades 34 to rotate synchronously. Each transverse stirring rod 331 and each spiral blade 34 respectively stir the materials in the stirring chamber 211; after the stirring is completed, the lifting drive mechanism 4 drives the lifting movable frame 5 to move upward, causing the kettle lid 22 to open upward and the stirring mechanism 3 to retreat from the stirring chamber 211, and then flipping the movable flipping sleeve 6 to flip the kettle body 21 so that the materials in the stirring chamber 211 can be conveniently poured out.

[0046] It should be emphasized that for the stirring mechanism 3 of the first embodiment, the spiral blades 34 are metal parts and have relatively high strength. Each spiral blade 34 is welded to the outer end of the transverse stirring rod 331 on its spiral path, that is, each spiral blade 34 connects all the transverse stirring rods 331 on its spiral path into a whole, and two spiral blades 34 can connect all the stirring rod groups 33 into a whole; therefore, the spiral blades 34 of the first embodiment can effectively increase the strength of the transverse stirring rods 331, and can make the strength of the entire stirring assembly better, thereby effectively meeting the stirring requirements of high-viscosity materials, having good stability and reliability and a longer service life.

[0047] In addition, during the process of the stirring mechanism 3 of the first embodiment stirring the materials, the transverse stirring rods 331 and the spiral blades 34 respectively stir the materials; compared with the prior art method of only using stirring blades to stir the materials, the stirring effect of the first embodiment is better and the stirring is more sufficient.

[0048] It should be further pointed out that during the process of the kettle lid 22 moving downward and closing on the upper end of the kettle body 21, in the first embodiment, the alignment mechanism between the kettle lid 22 and the kettle body 21 is used to align the kettle lid 22 and the kettle body 21 to ensure that the kettle lid 22 and the kettle body 21 remain relatively stationary during the stirring operation.

[0049] It should be further emphasized that the kettle body 21 of the first embodiment is firmly installed in the sleeve accommodating cavity 61 of the flipping sleeve 6. Since the flipping sleeve 6 is a flip - movable structure; when cleaning the stirring chamber 211 of the kettle body 21, the staff can flip the kettle body 21 to a comfortable operation position, thereby improving the convenience of the cleaning operation.

[0050] Based on the above - mentioned situation, it can be seen that through the above - mentioned structural design, the new experimental kettle device of the first embodiment has the advantages of novel structural design, convenient cleaning operation, and good stability and reliability.

[0053] Among them, the stirring drive motor 31 is screwed and fastened to the lifting movable frame 5, and the power output shaft of the stirring drive motor 31 is connected to the upper end of the stirring rotating shaft 32 through a coupling.

[0054] Embodiment 4, as Figure 2 shown, the difference between the fourth embodiment and the first embodiment is that: the alignment mechanism includes an alignment convex block 9 provided at the edge of the kettle lid 22 and protruding downward. A corresponding upward - opening alignment groove (not shown in the figure) is provided at the edge of the upper end of the kettle body 21 corresponding to the alignment convex block 9.

[0055] During operation, when the kettle lid 22 is closed on the upper end of the kettle body 21, the alignment convex block 9 of the kettle lid 22 is inserted into the alignment groove of the kettle body 21; through the cooperation of the alignment convex block 9 and the alignment groove, in the fourth embodiment, it can be ensured that the kettle body 21 and the kettle lid 22 remain stationary during the stirring operation.

[0056] Embodiment Five, as Figure 1 shown, the difference between the fifth embodiment and the first embodiment is that the lifting drive mechanism 4 includes a lifting drive oil cylinder 41 fixedly installed on the frame 1 and vertically moving, and the outer extension end of the piston rod of the lifting drive oil cylinder 41 is connected to the lifting movable frame 5.

[0057] A servo hydraulic pump station 42 is installed beside the lifting drive oil cylinder 41 on the frame 1, and the lifting drive oil cylinder 41 is connected to the servo hydraulic pump station 42 through a hydraulic pipeline.

[0058] A lifting guide pair 43 is installed between the lifting movable frame 5 and the frame 1.

[0060] Embodiment Six, the difference between the sixth embodiment and the first embodiment is that an electric heater is installed on the inner wall of the sleeve accommodation cavity 61 of the flipping sleeve 6, and the outer wall of the kettle body 21 is in contact with the electric heater.

[0061] The electric heater in the sixth embodiment is electrically connected to the PLC controller; when it is necessary to heat the materials in the stirring chamber 211 of the kettle body 21, the PLC controller controls the electric heater to start. At this time, the heat generated by the electric heater is conducted to the kettle body 21. The kettle body 21 is a metal structure, and the kettle body 21 then conducts the heat to the materials in the stirring chamber 211 to achieve the function of heating the materials.

[0062] Embodiment Seven, the difference between the seventh embodiment and the first embodiment is that the flipping sleeve 6 is equipped with a double-stroke hydraulic cylinder (not shown in the figure). The cylinder body of the double-stroke hydraulic cylinder is hinged to the frame 1, and the outer extension end of the piston rod of the double-stroke hydraulic cylinder is hinged to the flipping sleeve 6.

[0063] Among them, the double-stroke hydraulic cylinder is connected to the above-mentioned servo hydraulic pump station 42 through a hydraulic pipeline, and the double-stroke hydraulic cylinder is controlled by the PLC controller.

[0064] During operation, when the double-acting hydraulic cylinder is in the initial position, the kettle body 21 is in a vertical state and does not flip. At this time, the kettle cover 22 can be aligned with the kettle body 21. When the double-acting hydraulic cylinder is in the first stroke position, the flipping sleeve 6 rotates to the feeding position to facilitate the staff to add materials into the stirring chamber 211. When the double-acting hydraulic cylinder is in the second stroke position, the flipping sleeve 6 rotates to the cleaning position, which is convenient for pouring out the stirred materials from the stirring chamber 211 or performing flushing operations.
