Description

Technical Field

[0001] This utility model relates to the technical field of dichloroquinoline acid production equipment, and in particular to a high-efficiency enamel extraction kettle for dichloroquinoline acid production. Background Technology

[0002] In the field of pesticide production, quinclorac acid, as a highly efficient and low-toxicity quinoline carboxylic acid herbicide, is widely used for weed control in fields. Extraction is a crucial step in its production process, directly affecting product purity, yield, and production efficiency. The extraction process is generally completed in an enamel-lined extraction vessel, which is typically equipped with a stirring mechanism to accelerate liquid flow, enhance convection and diffusion, and prevent material sedimentation and agglomeration. However, traditional enamel-lined extraction vessels usually employ single-layer impellers or simple stirring structures, making it difficult to achieve efficient liquid-liquid two-phase mixing, resulting in low mass transfer efficiency, long extraction times, and impacting the production cycle. Therefore, this study aims to develop a high-efficiency enamel-lined extraction vessel for quinclorac acid production. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a high-efficiency enamel extraction vessel for the production of dichloroquinoline acid, comprising a base, with multiple legs evenly fixedly arranged circumferentially at the bottom of the base; an enamel vessel body rotatably mounted on the upper center of the base, and a first motor for driving the enamel vessel body to rotate on the base; a feed pipe and a discharge pipe connected to the interior of the enamel vessel body are respectively fixedly arranged at the upper and lower ends of the enamel vessel body; a second motor is fixedly arranged in the upper center of the enamel vessel body, and the drive shaft of the second motor is connected to a vertical rotating shaft rotatably arranged inside the enamel vessel body; a transmission box is inserted through the middle of the vertical rotating shaft inside the enamel vessel body; horizontal rotating shafts are rotatably arranged between the two ends of the transmission box and the inner circumferential wall of the enamel vessel body; the two horizontal rotating shafts located inside the transmission box are connected to the vertical rotating shaft; and multiple pairs of stirring rods are evenly spaced and fixedly arranged on the vertical rotating shaft and the two horizontal rotating shafts.

[0006] Furthermore, a transmission gear ring is fixedly fitted on the outer peripheral wall of the enamel-lined vessel near the lower end, and an installation groove is provided inside the base. The first motor is located inside the installation groove, and the drive shaft of the first motor extends above the base and has a drive gear at its free end that meshes with the transmission gear ring.

[0007] Furthermore, a plurality of wheel frames are evenly arranged circumferentially on the upper part of the base near the outer edge. Each wheel frame is rotatably provided with a limiting groove wheel on the side facing the enamel vessel body. A limiting protrusion ring is fixedly sleeved on the outer peripheral wall of the enamel vessel body at the position above the transmission gear ring. The limiting protrusion ring is rotatably engaged with the groove of each limiting groove wheel.

[0008] Furthermore, the discharge pipe is arranged to coincide with the axis of the enamel-lined kettle body and passes through the base, and an on / off valve is provided on the discharge pipe at a position outside the base.

[0009] Furthermore, the other two ends of the transmission box are respectively fixedly connected to the inner peripheral wall of the enamel-lined vessel body via horizontal connecting struts.

[0010] Furthermore, the vertical rotating shaft is fitted with a drive bevel gear inside the transmission box, and the opposite ends of the two horizontal rotating shafts extend into the transmission box and are respectively provided with driven bevel gears adapted to the drive bevel gear.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This invention uses a first motor to drive the enamel-lined vessel to rotate, and a second motor to drive a vertical shaft to rotate. The vertical shaft drives two horizontal shafts to rotate through the meshing transmission of a driving bevel gear and two driven bevel gears. The rotation of the enamel-lined vessel, combined with the multiple sets of stirring rods on the vertical shaft and the two driven shafts, stirs the liquid inside the enamel-lined vessel in different directions.

After the first motor is started, the enamel-lined vessel body rotates through the meshing transmission action of the drive gear and the transmission gear ring.

[0020] A plurality of wheel frames 8 are uniformly fixed circumferentially on the upper part of the base 1 near its outer edge. Each wheel frame 8 is rotatably mounted with a limiting groove wheel 9 facing the enamel-lined vessel body 3. A limiting protrusion ring 10 is fixedly fitted on the outer peripheral wall of the enamel-lined vessel body 3 above the transmission gear ring 5. The limiting protrusion ring 10 is rotatably engaged with the grooves of each limiting groove wheel 9. The limiting engagement between the limiting protrusion ring 10 and the plurality of limiting groove wheels 9 ensures the stability of the rotational movement of the enamel-lined vessel body.

The feed pipe 11 is detachably connected to an external feed pipeline. The discharge pipe 12 is arranged to coincide with the axis of the enamel-lined reactor body 3 and passes through the base 1. A matching on / off valve 13 is installed on the discharge pipe 12 at a position outside the base 1.

[0022] A second motor 14 is fixedly installed in the middle of the upper part of the enamel-lined vessel body 3. The drive shaft of the second motor 14 is connected to a vertical rotating shaft 15 rotatably installed inside the enamel-lined vessel body 3. The middle part of the vertical rotating shaft 15 is fixedly installed through a transmission box 16 in the middle of the enamel-lined vessel body 3.

Multiple pairs of stirring rods 21 are fixedly arranged at even intervals on the vertical rotating shaft 15 and the two horizontal rotating shafts 17.

[0023] This invention supplies the raw material liquid for dichloroquinoline acid production into the enamel-lined reactor body through a feed pipe. After the feeding is completed, the connection between the feed pipe and the external supply pipeline is disconnected. A first motor drives the enamel-lined reactor body to rotate, and a second motor drives a vertical shaft to rotate. The vertical shaft drives two horizontal shafts to rotate through the meshing of a driving bevel gear and two driven bevel gears.
