Technical Field

[0001] This utility model relates to the field of aniline technology, specifically to an aniline raw material mixing and feeding mechanism. Background Technology

[0002] Aniline, also known as aminobenzene, is an organic compound, a colorless, oily liquid that decomposes upon heating to 370°C. It is slightly soluble in water but readily soluble in organic solvents such as ethanol and ether. Aniline is one of the most important amines. It is mainly used in the manufacture of dyes, pharmaceuticals, and resins, and can also be used as a rubber vulcanization accelerator. It can also be used as a black dye. Its derivative, methyl orange, can be used as an indicator in acid-base titrations.

[0003] In the production of aniline, different raw materials need to be mixed. Since each different raw material tank corresponds to a separate set of feeding components, the cost of the feeding equipment is greatly increased and maintenance is inconvenient. Therefore, an aniline raw material mixing and feeding mechanism is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aniline raw material mixing and feeding mechanism, which has the advantages of being able to extract multiple raw materials with a single feeding device, saving costs, and being easy to maintain. It solves the problem that each different raw material tank corresponds to a separate feeding component, which greatly increases the cost of the feeding device and makes maintenance inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aniline raw material mixing and feeding mechanism, including a mixing tank, a feeding pipe connected to the top of the mixing tank, a connecting seat fixedly installed on the surface of the mixing tank, a liquid injection pipe connected to the top of the mixing tank, and a feeding assembly provided on the mixing tank and the connecting seat;

[0006] The feeding assembly includes a stepper motor fixedly mounted to the bottom of the connecting seat. The output shaft of the stepper motor passes through the connecting seat and is fixedly connected to a turntable. A placement frame is fixedly mounted on the top of the turntable. A slide rail is fixedly mounted on the left side of the mixing tank. An electric push rod is fixedly mounted on the left side of the mixing tank and below the slide rail. A slider is fixedly connected to the output shaft of the electric push rod. The slider is located inside the slide rail. A liquid extraction pipe is fixedly connected inside the slider. A liquid extraction pump is provided on the top of the mixing tank. The inlet of the liquid extraction pump is connected to a flexible hose.

[0007] Furthermore, one end of the hose is connected to a liquid pump, and the other end is connected to a liquid extraction pipe. The outlet of the liquid pump is connected to a straight pipe, and the bottom end of the straight pipe is connected to an annular pipe. The bottom of the annular pipe has a feed hole.

[0008] Furthermore, a stirring element is provided at the top and center of the mixing tank. The stirring element includes a servo motor, the output shaft of which extends into the interior of the mixing tank and is fixedly connected to a stirring shaft located inside the annular tube.

[0009] Furthermore, the number of feed holes is several, which are evenly and equidistantly distributed below the annular tube.

[0010] Furthermore, the length of the liquid extraction tube is greater than the length of the placement frame, and the liquid extraction tube is parallel to the mixing tank.

[0011] Furthermore, a discharge pipe is provided at the bottom of the mixing tank, and an electrically controlled valve is provided on the discharge pipe.

[0012] Furthermore, the outer perimeter of the placement frame is hollowed out, and the placement frame is circular.

[0013] Furthermore, a weighing sensor is provided on the inner bottom wall of the placement frame.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This aniline raw material mixing and feeding mechanism places tanks containing different raw materials inside a placement frame during the mixing of aniline raw materials. The raw material with a larger proportion is added to the mixing tank through the injection pipe. An electric push rod drives a slider to move, causing the extraction pipe to be inserted into the pre-reserved hole in the tank. Under the action of the extraction pump, the extraction pipe extracts the raw material in the tank. The extracted raw material is sprayed into the tank in sequence through the branch pipe and the annular pipe. Due to the distribution of the feed holes, the raw material can be evenly sprinkled in the tank, resulting in better mixing and improved mixing efficiency. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 The aniline raw material mixing and feeding mechanism in this embodiment includes a mixing tank 1, a feeding pipe 2 connected to the top of the mixing tank 1, a connecting seat 3 fixedly installed on the surface of the mixing tank 1, a liquid injection pipe 4 connected to the top of the mixing tank 1, and a feeding component 5 provided on the mixing tank 1 and the connecting seat 3.

[0023] A stirring element 6 is installed at the top and center of the mixing tank 1. The stirring element 6 includes a servo motor, the output shaft of which extends into the interior of the mixing tank 1 and is fixedly connected to a stirring shaft located inside the annular tube 512. The servo motor drives the stirring shaft to rotate, thereby mixing the raw materials in the mixing tank 1. A discharge pipe is installed at the bottom of the mixing tank 1, and an electrically controlled valve is installed on the discharge pipe.

[0024] The feeding assembly 5 includes a stepper motor 501 fixedly mounted to the bottom of the connecting base 3. The output shaft of the stepper motor 501 passes through the connecting base 3 and is fixedly connected to a turntable 502. A placement frame 503 is fixedly mounted on the top of the turntable 502. The outer peripheral wall of the placement frame 503 is hollowed out, and the placement frame 503 is circular. A weighing sensor 504 is provided on the inner bottom wall of the placement frame 503. A slide rail 505 is fixedly mounted on the left side of the mixing tank 1. An electric push rod 506 is fixedly mounted on the left side of the mixing tank 1 and below the slide rail 505. The output shaft of the electric push rod 506 is fixedly connected to a slider 507. The slider 507 is located inside the slide rail 505. A liquid extraction pipe 508 is fixedly connected inside block 507. The length of the liquid extraction pipe 508 is greater than the length of the placement frame 503. The liquid extraction pipe 508 is connected to the mixing tank 1. A liquid extraction pump 509 is installed on the top of the parallel mixing tank 1. The inlet of the liquid extraction pump 509 is connected to a hose 510. One end of the hose 510 is connected to the liquid extraction pump 509, and the other end is connected to the liquid extraction pipe 508. The outlet of the liquid extraction pump 509 is connected to a straight pipe 511. The bottom end of the straight pipe 511 is connected to an annular pipe 512. The bottom of the annular pipe 512 is provided with a feed hole 513. There are several feed holes 513, which are evenly and equidistantly distributed below the annular pipe 512.

[0025] Tanks filled with different raw materials are placed inside the placement frame 503. When different raw materials need to be extracted, the stepper motor 501 drives the turntable 502 to rotate, positioning the different tanks below the extraction pipe 508. Before rotation, the electric push rod 506 drives the slider 507 to slide upwards to the top in the slide rail 505. After the turntable 502 stops, the electric push rod 506 drives the extraction pipe 508 on the slider 507 to move downwards, inserting the extraction pipe 508 into the pre-drilled hole in the tank. Under the action of the extraction pump 509, the extraction pipe 508 extracts the raw materials from the tank. The extracted raw materials are sprayed into the tank sequentially through the branch pipe 511 and the annular pipe 512. Due to the distribution of the feed holes 513, the raw materials can be evenly sprinkled in the tank, resulting in better mixing and improved mixing efficiency. The weighing sensor 504 monitors the weight of the tank. The weight changes during extraction, allowing for clear knowledge of the extracted amount and facilitating control of the aniline ratio.

[0026] The working principle of the above embodiments is as follows:

[0027] When mixing raw materials for aniline, tanks containing different raw materials are placed inside the placement frame 503. Raw materials with a large proportion, such as nitrobenzene solution, are added to the mixing tank 1 through the injection pipe 4. The electric push rod 506 drives the slider 507 to move, so that the extraction pipe 508 is inserted into the reserved hole in the tank. Under the action of the extraction pump 509, the extraction pipe 508 extracts the raw materials in the tank. The extracted raw materials are sprayed into the tank in sequence through the branch pipe 511 and the annular pipe 512. Due to the distribution of the feed holes 513, the raw materials can be evenly sprinkled in the tank, which can better mix them and improve the mixing efficiency. Thus, a single set of feeding equipment can extract multiple raw materials, saving costs and making maintenance convenient.
