Description

Technical Field

[0001] This utility model relates to the field of nitration reactor technology, specifically a nitration reactor feeding device. Background Technology

[0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization and condensation. Examples include reactors, reaction vessels, decomposition vessels, polymerization vessels, etc. The materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials.

[0003] Currently, when using nitration reactors, feeding is done manually. However, this requires workers to insert the feed bucket into the feed inlet and support it until feeding is complete before removing it. This is physically demanding, and prolonged work can easily lead to arm pain for workers, thus affecting their work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for a nitration reactor to solve the problem mentioned in the background art that the current nitration reactor is fed manually. However, the manual feeding process requires the operator to insert the feed bucket into the feeding port and support it until the feeding is completed before removing the bucket. This is physically demanding and can easily cause arm pain for the operator, thus affecting their work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for a nitration reactor, comprising a reactor and a feeding port, wherein the feeding port is provided on the right side of the top of the reactor, and the feeding device for the nitration reactor further comprises: a support mechanism provided on the right side of the reactor; and an auxiliary mechanism provided on the outside of the feeding port.

[0006] The electric push rod is pushed diagonally upward, and then the limiting block drives the rotating plate to rotate at the top of the connecting rod. During the rotation, when the rotating plate moves in an arc, the limiting block slides inside the rotating plate to assist in limiting the movement. Then, when the rotating plate rotates, it drives the material bucket to move at the same time. When the material bucket tilts to the same angle as the baffle, the user controls the electric push rod to stop working through the external control unit.

[0007] Preferably, the stop bar is arc-shaped.

[0008] Preferably, the baffle is semi-circular in shape and made of a smooth metal material.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the feeding device of the nitration reactor is put into use, the support mechanism supports the material tank and adjusts its tilt angle. The auxiliary mechanism protects the bottom of the feeding port when feeding through the support mechanism, preventing the raw materials from spilling. Through the combined use of the above structures, the problem of workers needing to support the material tank for a long time when feeding the reactor is solved, and the problem of the high workload of supporting for a long time affecting the work progress of subsequent workers is solved.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a feeding device for a nitration reactor, including a reactor 1 and a feeding port 2. The feeding port 2 is provided on the right side of the top of the reactor 1. The feeding device for the nitration reactor also includes: a support mechanism 3 provided on the right side of the reactor 1, and an auxiliary mechanism 4 provided on the outside of the feeding port 2. The support mechanism 3 is used to support and tilt the material tank when feeding the reactor 1, and the auxiliary mechanism 4 can prevent the material from spilling during feeding.

[0017] Specifically, the support mechanism 3 includes: a connecting rod 301, a rotating plate 302, a stop rod 303, a support plate 304, and an electric push rod 305;

[0018] The connecting rod 301 is fixedly installed on the right outer wall of the reactor 1. The connecting rod 301 is used to support the rotating plate 302. The rotating plate 302 is rotatably installed at the top of the connecting rod 301. When the rotating plate 302 is tilted, the material bucket can be tilted and the material can be added into the interior of the reactor 1. A stop bar 303 is fixedly mounted on the top of the rotating plate 302. The stop bar 303 is used to limit the movement of the material bucket. A support plate 304 is fixedly mounted on the right side of the connecting rod 301. An electric push rod 305 is tilted and rotatably mounted on the top of the support plate 304. A limiting block 306 is rotatably mounted on the top of the electric push rod 305, and the limiting block 306 can be laterally moved inside the rotating plate 302. The limiting block 306 is used to provide sufficient space for its connection when the electric push rod 305 pushes the rotating plate 302 to rotate, so that the electric push rod 305 can rotate the rotating plate 302. When the electric push rod 305 tilts upward, it can drive the rotating plate 302 to rotate. During the rotation of the rotating plate 302, the limiting block 306 slides inside the rotating plate 302 to limit the movement.

[0019] More specifically, the auxiliary mechanism 4 includes: a slot plate 401, a slider 402, and a baffle 403;

[0020] The trough plate 401 is fixedly installed on the top right side of the reactor 1 and is located outside the feed port 2. The trough plate 401 is used to support the slider 402 and the baffle 403. The slider 402 is movably installed inside the trough plate 401, and the baffle 403 is fixedly installed on the top of the slider 402. The baffle 403 can slide inside the trough plate 401 through the slider 402. The inside of the trough plate 401 is provided with a groove that matches the slider 402. The baffle 403 is semi-circular in shape and is made of smooth metal.

[0021] Working Principle: When the feeding device for the nitration reactor is first used, and it is necessary to feed the inside of reactor 1, the user first places the material bucket containing the raw material into the top of the rotating plate 302. The baffle 403 is used to limit the material bucket and prevent it from swaying left and right. Then, the user slides the baffle 403 to the bottom of the feeding port 2 by sliding the slider 402 inside the trough plate 401. Then, the user controls the electric push rod 305 to start working through the external control unit. The electric push rod 305 is pushed diagonally upward, and then the limiting block 306 drives the rotating plate 302 to rotate at the top of the connecting rod 301. During the rotation, when the rotating plate 302 moves in an arc, the limiting block 306 slides inside the rotating plate 302 to assist in limiting the movement. Then, when the rotating plate 302 rotates, it drives the material bucket to move simultaneously. When the material bucket tilts to the same angle as the baffle 403, the user... The user controls the electric push rod 305 to stop working via the external control unit. Then, due to the weight of the material barrel, the barrel slides downward at the top of the rotating plate 302 and is blocked by the baffle 403, so that the outer wall of the material barrel is attached to the top of the baffle 403. Then, the user removes the cover plate in the material barrel, and the raw material inside the material barrel is discharged downward to the top of the baffle 403. Then, the discharged raw material is transported into the interior of the reactor 1 by the tilt angle of the baffle 403. After the feeding is completed, the user controls the electric push rod 305 to reset via the external control unit, pulling the rotating plate 302 downward. When the electric push rod 305 is fully reset, the bottom end of the rotating plate 302 is attached to the top of the connecting rod 301. Then, the user removes the material barrel and slides the baffle 403 back to its original position inside the trough plate 401 via the slider 402. Then, the user closes the feeding port 2 and stirs and heats the raw material in the reactor 1.
