[0022] The heating and stirring production device according to the first aspect embodiment of the present invention includes a stirring unit, a conveying unit, and an inductive heating unit.

[0023] Refer to Figure 4 , the stirring unit includes a tank body 100. The tank body 100 is in the shape of a vertically arranged cylinder. The bottom of the tank body 100 is closed, and the top of the tank body 100 is provided with an open mouth. The edge of the open mouth is called the first edge 102, and a tank cover 200 is provided at the open mouth; the tank body 100 has a tank side wall 103, and the tank side wall 103 is the outer peripheral wall of the tank body 100.

A partition member 400 is provided between the stirring cavity 402 and the return cavity 101, and the partition member 400 is also in the shape of a vertically arranged cylinder.

[0024] A stirrer is provided in the stirring cavity 402. The stirrer is rotatably arranged on the tank cover 200, and the tank body 100 is provided with a driving device 300 for driving the stirrer; both the tank side wall 103 and the partition member 400 are metal components; The tank body 100 is provided with a feed port 304 connected to the stirring chamber 402. The feed port 304 can be set on the first edge 102, and the feed port 304 can also be set on the tank cover 200, as long as it can be connected to the stirring chamber 402; the top of the tank body 100 is provided with a discharge port 403 connected to the reflux chamber 101, and the discharge port 403 is set on the top of the tank side wall 103. Of course, the discharge port 403 can also be set on the first edge 102; the bottom of the partition 400 is provided with a first opening 410 connected to the reflux chamber 101, and the partition 400 is used to separate the stirring chamber 402 and the reflux chamber 101, so that the stirring chamber 402 and the reflux chamber 101 can only be connected through the first opening 410.

[0025] The conveying unit includes a conveying pipe 800, which is connected between the feed port 304 and the discharge port 403. The conveying pipe 800 is provided with a liquid conveyor 820, which can be a centrifugal pump. The feed port 304 is located at the top of the left side of the tank body 100. The conveying pipe 800 has a first pipe section and a second pipe section. The first pipe section is arranged horizontally, the right end of the first pipe section is connected to the feed port 304, and the left end of the first pipe section is connected to the liquid suction port of the liquid conveyor 820. The second pipe section is arranged vertically, the top end of the second pipe section is connected to the feed port 304, and the bottom end of the second pipe section is connected to the liquid discharge port of the liquid conveyor 820. The induction heating unit includes an induction coil 900 spirally wound around the outer circumference of the tank body 100 and a control cabinet 910 for controlling the operation of the induction coil 900 .

[0026] When in use, after adding the material to be stirred and mixed into the stirring chamber 402, the driving device 300 can be started, and the driving device 300 drives the stirrer to rotate to achieve stirring of the material; at the same time, an alternating current is applied to the inductor 900, and an alternating magnetic field is generated around the inductor 900, and eddy currents are induced inside the tank side wall 103 and the partition 400 in the magnetic field. When the eddy currents flow inside the tank side wall 103 and the partition 400, heat is generated due to the resistance of the material, thereby achieving heating; wherein, by setting the partition 400, the partition 400 00 on one side of the stirring chamber 402, the surface of the partition 400 on one side of the reflux chamber 101, and the surface of the tank side wall 103 on one side of the reflux chamber 101 are all in contact with the material, so that the heating area is larger, which is beneficial to improving the heating speed; by setting the feed port 304, the discharge port 403, the reflux chamber 101 and the conveying unit, the material in the stirring chamber 402 can circulate between the agitator, the reflux chamber 101, and the conveying pipe 800, further enhancing the stirring effect, while the material in various places in the tank body 100 can be evenly heated.

[0027] In addition, compared with conventional electric heating wire heating, induction heating has higher energy conversion efficiency.

[0028] In some embodiments of the present invention, the agitator includes a tubular stirring shaft 310 and stirring blades 312 provided on the stirring shaft 310. The stirring shaft 310 is vertically arranged, and the stirring blades 312 are connected to the outer peripheral surface of the stirring shaft 310. The number of the stirring blades 312 is multiple; the top end of the stirring shaft 310 is arranged outside the tank body 100, and the top end of the stirring shaft 310 is a feed port 304. A return port 311 is provided at the bottom end of the stirring shaft 310. The feed port 304 and the return port 311 are communicated through the inside of the stirring shaft 310. The stirring shaft 310 is a metal component. In this way, the side wall of the stirring shaft 310 can also be heated by the alternating magnetic field generated by the inductor coil 900, making full use of the alternating magnetic field, further increasing the heating area, further improving the energy conversion efficiency, and being beneficial to improving the heating speed; by providing the return port 311 at the bottom end of the stirring shaft 310, the material can flow vertically through the entire stirring shaft 310, reducing the flow dead angle.

[0029] Further, the stirring shaft 310 is installed on the tank cover 200; the tank cover 200 is provided with a first through hole, the stirring shaft 310 vertically penetrates through the first through hole, and a third sealing ring 333 is provided between the stirring shaft 310 and the hole wall of the first through hole to prevent external sundries from falling into the stirring cavity 402; the stirring shaft 310 has a first shaft section and a second shaft section. The first shaft section is arranged on the upper side of the first through hole, and the second shaft section is arranged on the lower side of the first through hole. The stirring blades 312 are arranged on the second shaft section, and a plurality of return ports 311 are provided on the side wall of the second section. The plurality of return ports 311 are arranged at intervals in the vertical direction in sequence; in this way, as the stirring shaft 310 rotates, the material flowing back under the action of centrifugal force can flow out from the plurality of return ports 311, which is beneficial to the uniform mixing of the material flowing back and the material in the stirring cavity 402.

[0030] The first shaft section is provided with a shoulder. A gear, a pulley or other suitable transmission component is sleeved on the upper side of the shoulder of the first shaft section to be drivingly connected to the driving device 300. A tapered roller bearing 320 is sleeved on the lower side of the shoulder of the first shaft section. The tapered roller bearing 320 is arranged between the shoulder and the tank cover 200, so that the stirring shaft 310 can bear both radial force and axial force, and the structure is stable.

[0031] It is understandable that the utensils used for food production need to be cleaned internally frequently to maintain health and hygiene. Therefore, in order to facilitate cleaning so that the heating and stirring production device can be applicable to food production, in some embodiments of the present invention, a tank cover 200 is provided at the top of the tank body 100. The edge of the open mouth and the partition member 400 both abut against the bottom of the tank cover 200. An upwardly concave avoidance groove 201 is provided at the bottom of the tank cover 200. The avoidance groove 201 is provided above the open mouth. The outer peripheral edge of the tank cover 200 abuts against the first edge 102 from top to bottom. A first sealing ring 331 is provided between the first edge 102 and the tank cover 200. The partition member 400 is detachably inserted into the tank body 100 in the vertical direction. The bottom of the partition member 400 abuts against the bottom of the tank body 100. The top of the partition member 400 protrudes from the open mouth out of the tank body 100. The top of the partition member 400 extends into the avoidance groove 201 and abuts against the top wall of the avoidance groove 201. A second sealing ring 332 is provided between the partition member 400 and the top wall of the avoidance groove 201. The conveying pipe 800 and the feed inlet 304 are connected by a detachable structure. Refer to Figure 6 , after the conveying pipe 800 and the feed inlet 304 are disassembled, the tank cover 200 and the stirrer are taken out, and then the partition member 400 is taken out, so as to facilitate the cleaning of the inside of the stirrer, the partition member 400, and the tank body 100.

[0032] A lifting ring can be provided on the tank cover 200 to facilitate the taking and placing of the tank cover 200 by means of hoisting. A second edge 401 can be provided on the inner side of the top of the partition member 400 to facilitate hanging a lifting hook on the second edge 401 to take and place the partition member 400 by means of hoisting. At the same time, the second edge 401 can also be used to provide the second sealing ring 332 to avoid the problem that it is difficult to provide the second sealing ring 332 due to the too small top surface area of the partition member 400.

[0033] It should be noted that, in order to facilitate the insertion of the partition member 400, the open mouth and the partition member 400 are in clearance fit or the inner diameter of the open mouth is slightly smaller than the outer diameter of the partition member 400, which will result in poor sealing performance between the open mouth and the partition member 400, and further result in poor effect of the liquid conveyor 820 sucking the material in the reflux chamber 101, which is not conducive to the circular flow of the material.

[0034] In this embodiment, a first sealing ring 331 and a second sealing ring 332 are provided. The first sealing ring 331 can seal between the tank cover 200 and the tank body 100 to block the entry of external air into the reflux chamber 101 between the open mouth and the partition member 400. The second sealing ring 332 can seal between the tank cover 200 and the partition member 400 to block the entry of air in the stirring chamber 402 into the reflux chamber 101 between the open mouth and the partition member 400, so that the reflux chamber 101 has good sealing performance.

[0035] In some embodiments of the present invention, refer to Figure 2, the conveying pipe 800 has a swing section 803 which extends laterally. The swing section 803 is arranged above the tank body 100 and spans the edge of the tank body 100. The two ends of the swing section 803 are respectively called the first end and the second end. The second end is connected to the detachable structure, and a vertically arranged first rotary joint 831 is connected between the first end and the liquid conveyor 820. The rotary joint is a conventional component in the art and can be directly purchased, so its specific structure will not be elaborated here. The first rotary joint 831 is arranged at the top of the second pipe section; by setting the first rotary joint 831, after the swing section 803 is separated from the feed inlet 304, it can swing to a position far away from the upper part of the tank body 100, so that the heating and stirring production device is in the discharging state. Refer to Figure 3 , then the swing section 803 will not prevent the upward removal of the tank cover 200 and the partition member 400. Moreover, at this time, starting the liquid conveying device can make the materials that have been stirred and processed in the stirring chamber 402 be sent out from the second end, achieving the purpose of discharging.

[0036] Among them, the detachable structure includes a telescopic pipe 840 and a socket 841. The telescopic pipe 840 is arranged vertically. The socket 841 includes an insertion pipe and a cap sleeved outside the insertion pipe. The telescopic pipe 840 is connected between the top of the insertion pipe and the second end. The bottom end of the insertion pipe is inserted into the feed inlet 304. The cap is arranged above the feed inlet 304, and a downward convex edge is provided on the outer edge of the cap to prevent external dust and other sundries from falling into the stirring shaft 310 between the cap and the feed inlet 304. Lifting the cap socket 841 upward can realize the separation of the conveying pipe 800 from the feed inlet 304. The structure is simple and the operation is convenient.

[0037] In some embodiments of the present invention, refer to Figure 5The driving device 300 includes a first gear 301, a second gear 302 and a rotary driver for driving the first gear 301 to rotate. The rotary driver can be a motor. The rotary driver has a main body and an output shaft. The main body is arranged on the tank body 100. The first gear 301 is arranged on the output shaft. The second gear 302 is meshed with the first gear 301. The second gear 302 is linked to the stirring shaft 310. The second gear 302 is transmission-connected between the first gear 301 and the stirring shaft 310. 302 is rotatably connected to the tank cover 200, the second gear 302 is arranged on the upper side of the tank cover 200, the stirring shaft 310 is provided with a third gear 303, the second gear 302 is meshed with the third gear 303, that is, the second gear 302 and the stirring shaft 310 are linked and connected, the axial directions of the first gear 301, the second gear 302 and the third gear 303 are all vertical, the first gear 301 is arranged outside the tank cover 200 along the radial direction of the tank cover 200, that is, the horizontal projection of the first gear 301 is arranged outside the tank cover 200. In this way, when the tank cover 200 is taken out upward, the first gear 301 is separated from the second gear 302, and the first gear 301 will not block the upward movement of the tank cover 200; at the same time, the rotary driver is arranged on the tank body 100, so that there will be no wire involved when taking out the tank cover 200, which is convenient for taking out the tank cover 200.

[0038] In some embodiments of the present invention, the reflux chamber 101 is provided with a spiral blade 420 surrounding the partition 400. It is understandable that if the spiral blade 420 is not provided, the material in the reflux chamber 101 will flow along the shortest path between the first opening 410 and the discharge port 403, resulting in a large range of flow dead angles in the reflux chamber 101; in this embodiment, by providing the spiral blade 420, the material can flow upward in the reflux chamber 101 in a spiral manner, reducing the flow dead angle, which is conducive to fully taking away the heat from various places in the reflux chamber 101.

[0039] In some embodiments of the present invention, the delivery pipe 800 is provided with a first bypass interface and a first stop valve 811, which are respectively arranged between the liquid conveyor 820 and the discharge port 403; the first bypass interface is provided with a feed pipe 801, and the feed pipe 801 is provided with a second stop valve 812. The first stop valve 811 is used to control the on-off of the flow channel from the discharge port 403 to the liquid conveyor 820, and the second stop valve 812 is used to control the on-off of the flow channel from the feed pipe 801 to the liquid conveyor 820; when the first stop valve 811 is controlled to be turned on and the second stop valve 812 is turned off, the material can circulate between the stirring chamber 402, the reflux chamber 101, and the conveying pipe 800; when the first stop valve 811 is controlled to be turned off and the second stop valve 812 is controlled to be turned on, production raw materials can be added to the feed pipe 801, and the liquid conveyor 820 can deliver the production raw materials into the stirring chamber 402, which is convenient for feeding the stirring chamber 402, wherein the tank cover 200 can be provided with a vent to balance the air pressure in the stirring chamber 402.

[0040] In some embodiments of the present invention, with reference to Figure 1 , a second rotary joint 832 is connected between the conveying pipe 800 and the feed port 304. The conveying pipe 800 is provided with a second bypass interface and a third stop valve 813. The second bypass interface and the third stop valve 813 are sequentially arranged between the liquid conveyor 820 and the feed port 304. The second bypass interface is provided with a discharge pipe 802, and the discharge pipe 802 is provided with a fourth stop valve 814.

[0041] When the product produced by stirring is a chemical product and it is necessary to prevent harmful gases from overflowing during the stirring process, a second rotary joint 832 with better sealing performance is connected between the conveying pipe 800 and the feed port 304, so that the material can smoothly flow from the conveying pipe 800 to the stirring shaft 310 while the conveying pipe 800 does not interfere with the rotation of the stirring shaft 310; the third stop valve 813 is used to control the on-off of the flow path between the liquid conveyor 820 and the feed port 304, and the fourth stop valve 814 is used to control the on-off of the flow path between the liquid conveyor 820 and the discharge pipe 802; when the third stop valve 813 is controlled to be conducted and the fourth stop valve 814 is controlled to be cut off, the material can circulate between the stirring chamber 402, the reflux chamber 101, and the conveying pipe 800; when the third stop valve 813 is controlled to be cut off and the fourth stop valve 814 is controlled to be conducted, the liquid conveyor 820 can send out the product after the stirring process from the discharge pipe 802. In this embodiment, the requirement for cleaning the separation member 400 is not high. Therefore, the driving device 300 can be arranged on the tank cover 200 to simplify the structure.

[0042] The heating and stirring production method according to the second aspect embodiment of the present invention uses the above-mentioned heating and stirring production device for stirring production.
