[0001] The present application relates to the technical field of chemical production equipment, and in particular to a stirring and feeding device for an enamel kettle. Background Art

[0002] The enameled kettle is an enameled reactor, which is a corrosion-resistant reactor.

[0003] The production of tetrasodium glutamate diacetate is often carried out in an enamel kettle, and the materials are added in stages during the reaction process. During the initial addition, due to the low liquid level, the paddles of the enamel kettle are difficult to stir the initial additions evenly, which causes some unstirred raw materials to sink to the discharge port. As a result, the stirring is uneven during the production of tetrasodium glutamate diacetate, and the discharge port will occupy the raw materials that have not participated in the reaction during discharge, resulting in the problem of reduced product purity. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a stirring and feeding device for an enamel kettle.

[0033] refer to Figure 1 and Figure 2 The stirring and feeding device of the enamel kettle comprises a bottom ring plate 1, a closing plate 2, an extension rod 3, a mounting seat 4, a sealing seat 5 and a mounting frame 6. The sealing seat 5 is installed at the top middle position of the kettle body top cover and is made of corrosion-resistant rubber material. The mounting frame 6 is installed on the kettle body top cover, and a telescopic cylinder 61 is installed on the top. The piston rod of the telescopic cylinder 61 is set downward and passes through the top of the mounting frame 6 and is fixedly connected to the mounting seat 4. The mounting seat 4 is a frame structure, and the motor is installed in the mounting seat 4. The rotating shaft of the motor passes through the mounting seat 4 and extends downward into the kettle body and is fixedly connected to the stirring rod of the kettle body. The telescopic cylinder 61 can drive the mounting seat 4 to move to a position where it is tightly sealed with the sealing seat 5.

[0034] refer to Figure 2 and Figure 3 The bottom ring plate 1 is clamped on the inner wall of the middle of the discharge port of the kettle body and fixed by bonding. A plurality of connecting plates 11 extending toward the center of the bottom ring plate 1 are fixedly arranged on the inner wall of the bottom ring plate 1. The plurality of connecting plates 11 are evenly distributed around the circumference. A middle ring 12 is fixedly arranged at one end of the plurality of connecting plates 11 close to each other, and a guide rod 21 is abutted and slidably arranged on the inner wall of the middle ring 12.

[0035] refer to Figure 3 and Figure 4, the closing plate 2 is fixedly mounted on the top of the guide rod 21, and an anti-slip plate 211 is installed at the bottom of the guide rod 21, and the anti-slip plate 211 and the guide rod 21 are installed in a threaded connection. A reset spring 22 is sleeved on the guide rod 21, and the bottom end of the reset spring 22 abuts against the middle ring 12, and the top end abuts against the closing plate 2. When the reset spring 22 is in a natural state, the closing plate 2 is located above the discharge port of the kettle body, and at this time, the anti-slip plate 211 abuts against the lower surface of the middle ring 12. The reset spring 22 enables the closing plate 2 to lift the material above. An abutment column 23 is fixedly mounted on the upper surface of the closing plate 2, and the top end of the abutment column 23 is an arc-shaped protrusion. The circumferential outer wall of the abutment column 23 is in a conical transition shape from the top to the bottom. The extension rod 3 is fixedly mounted at the bottom center of the stirring paddle of the kettle body, and an abutment groove 33 abutting against the abutment column 23 is provided at the bottom end. After the mounting seat 4 and the sealing seat 5 are tightly sealed, the bottom end of the extension rod 3 abuts against the abutment column 23 and presses the closing plate 2 to a position that closes the top of the kettle body discharge port. The guide rod 21 is provided with a vertical slide groove, and the inner wall of the middle ring 12 abuts against the slide groove of the guide rod 21, thereby limiting the rotation of the guide rod 21.

[0036] The bottom ring plate 1 is installed at the discharge port of the kettle body. After the mounting seat 4 and the sealing seat 5 are tightly sealed, the extension rod 3 is abutted against the top of the abutment column 23 through the abutment groove 33 and drives the closing plate 2 to move down, so that the closing plate 2 closes the top of the discharge port. Therefore, no unmixed raw materials will enter the discharge port during the initial feeding, and the discharge of unreacted raw materials is reduced during the discharge, thereby improving the purity of the product. The arc convex setting at the top of the abutment column 23 can cooperate with the abutment groove 33 to improve the stability of the position of the closing plate 2 when the stirring rod of the kettle body rotates. The conical setting of the abutment column 23 can effectively make the top material flow downward, reducing the probability of the material staying on the abutment column 23. After the mounting seat 4 moves up, the reset spring 22 can drive the closing plate 2 to move up to open the top of the discharge port, and then open the valve of the kettle body discharge port for discharge.

[0037] refer to Figure 2 A plurality of first paddle blades 31 are fixedly provided at the bottom of the circumferential outer wall of the extension rod 3, and the plurality of first paddle blades 31 are equidistantly distributed in a circle with the central axis of the extension rod 3 as the center. The first paddle blades 31 are inclined in the same rotation direction, and in the rotation direction of the extension rod 3, the material contacted by the first paddle blades 31 will flow upward. A plurality of second paddle blades 32 are fixedly provided at the bottom of the circumferential outer wall of the extension rod 3 and above the first paddle blade 31. The length of the second paddle blade 32 is greater than that of the first paddle blade 31, and the inclination direction of the second paddle blade 32 is opposite to that of the first paddle blade 31. The position of the second paddle blade 32 is located above two adjacent second paddle blades 32. A same reinforcement ring 311 is fixedly provided at the end of the first paddle blade 31 away from the extension rod 3, and the reinforcement ring 311 is also fixedly provided at the end of the second paddle blade 32 away from the extension rod 3.

[0038] During the rotation of the stirring rod of the kettle body, the first blade 31 and the second blade 32 are driven to rotate by the extension rod 3, thereby stirring and mixing the materials in the bottom area of the kettle body, thereby improving the uniformity of the stirring and mixing of the materials during the initial feeding, thereby improving the purity of the product. The position setting and the inclination angle setting of the first blade 31 and the second blade 32 can effectively improve the mixing degree of the contacted materials, and at the same time, the structure is reinforced by the reinforcement ring 311 to improve the structural strength of the first blade 31 and the second blade 32.

[0039] The implementation principle of the stirring and feeding device of an enamel kettle in the embodiment of the present application is as follows: after the mounting seat 4 and the sealing seat 5 are tightly sealed, the extension rod 3 abuts against the abutment column 23 and drives the closing plate 2 to close the top of the kettle body discharge port, and then the initial feeding is carried out. In this way, the raw materials for the initial feeding will not enter the kettle body discharge port, reducing the situation where the raw materials mixed with the reaction are discharged during the discharge, thereby improving the purity of the product. During the rotation of the stirring rod of the kettle body, the extension rod 3 can evenly stir the initial raw materials at the bottom of the kettle body through the first paddle 31 and the second paddle 32, thereby improving the purity of the product and the utilization rate of the raw materials.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
