Description

Technical Field

[0001] The utility model relates to the field of reaction kettles, and particularly relates to a reaction kettle for preparing p-hydroxybenzoic acid. Background Art

[0002] At present, the Chinese utility model with the publication number CN204365299U discloses a reaction kettle with a stirring function, which includes: a reaction kettle body, a stirring rod, a servo motor and a stirring paddle. A stirring rod is arranged at the center inside the reaction kettle body, and one side of the stirring rod extends to the outside of the reaction kettle body. A servo motor is arranged at the top of the stirring rod, and a stirring paddle is arranged at the bottom of the stirring rod. The stirring paddle is in a W shape. An observation window and a pressure gauge are arranged at the top of the reaction kettle body, and a protective sleeve is arranged on the outer side of the reaction kettle body. The stirring paddle in this reaction kettle can fully stir the substances in the reaction kettle evenly, and the stirring situation can be observed at any time;

[0003] Although the existing reaction kettle is equipped with a stirrer inside and can agitate the internal materials by the drive of a motor, there are still other problems in the use process, such as poor stirring effect. The existing stirrer can only perform a one-way rotation stirring function at the center of the kettle, and the required stirring time is relatively long, making it difficult to fully mix the internal raw materials evenly. Moreover, it does not have a detachable impurity removal function. The raw materials in the reaction kettle often contain certain impurities when put in. After the raw materials are stirred and reacted and then discharged, the impurities will be discharged into the collection container together with the raw materials, causing a certain burden on the subsequent screening by personnel and having relatively low practicability. In order to solve the above problems, we propose a reaction kettle for preparing p-hydroxybenzoic acid. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a reaction kettle for preparing p-hydroxybenzoic acid, which solves the problems of poor internal stirring effect and lack of detachable impurity removal function of the existing reaction kettle.

[0005] The above technical objective of the utility model is achieved through the following technical solutions: A reaction kettle for the preparation of p-hydroxybenzoic acid, including a kettle barrel, a kettle cover is bolted to the top of the kettle barrel, a first motor is bolted to the top of the kettle cover, the output end of the first motor is fixedly sleeved with a first stirring assembly through a coupling, a second motor and a fixed frame are respectively bolted to the top and bottom of the kettle cover, a rotating part is rotatably connected inside the fixed frame through a bearing, a first gear and a second stirring assembly are fixedly sleeved on the surface of the rotating part, the output end of the second motor is fixedly sleeved with a second gear meshing with the first gear, a discharge pipe valve penetrates and communicates with the bottom of the kettle barrel, a fixed seat is slidably sleeved on the surface of the discharge pipe valve, a metal filter screen fitting the discharge pipe valve is installed inside the fixed seat, fixing plates are symmetrically welded to the top of the fixed seat, a threaded rod penetrates and is threadedly connected to one side of the fixing plate, and the other end of the threaded rod is rotatably connected to a clamping plate.

[0006] Adopting the above technical solutions, it is possible to achieve good stirring effect. Through two-way stirring, the mixing efficiency of the internal raw materials can be improved, ensuring the mixing quality and uniformity of the internal raw materials. At the same time, it can have a detachable impurity removal function, which is simple and convenient to operate. It intercepts impurities in the raw materials during discharge, reducing the subsequent screening burden on personnel and having high practicability.

[0007] The utility model is further arranged as: Support seats are equidistantly installed on the surface of the kettle barrel.

[0008] Adopting the above technical solutions, through the setting of the support seats, the device can be erected on the ground with good stability.

[0009] The utility model is further arranged as: Both the first stirring assembly and the second stirring assembly are made of stainless steel.

[0010] Adopting the above technical solutions, the first stirring assembly and the second stirring assembly have the characteristics of high strength, low density and excellent corrosion resistance.

[0011] The utility model is further arranged as: Anticorrosive coatings are applied to the surfaces of both the kettle barrel and the kettle cover.

[0012] Adopting the above technical solutions, through the setting of the anticorrosive coatings, the anti-corrosion effect on the surfaces of the kettle barrel and the kettle cover can be improved, extending the service life of the kettle barrel and the kettle cover.

[0013] The utility model is further arranged as: A limiting rod is welded to one side of the clamping plate, and the other end of the limiting rod penetrates and extends outside the fixing plate.

[0014] Adopting the above technical solutions, through the setting of the limiting rod, the clamping plate can be limited to prevent the clamping plate from flipping during the left and right movement.

[0015] The present utility model is further configured such that: a rotary handle is welded to the other end of the threaded rod.

[0016] With the above technical solution, through the setting of the rotary handle, it is convenient for personnel to rotate the threaded rod.

[0017] To sum up, the present utility model has the following beneficial effects:

[0018] 1. In the present utility model, the raw materials are first fed in from the feed port on the surface of the kettle barrel. After the raw materials are fed in, the first motor and the second motor are started simultaneously. After starting, the first motor drives the first stirring assembly to rotate clockwise through the cooperation of the coupling. After starting, the second motor drives the rotating member to rotate counterclockwise through the cooperation of the second gear and the first gear. When the rotating member rotates counterclockwise, it drives the second stirring assembly to rotate together, which can achieve good stirring effect. Through two-way stirring, the mixing efficiency of the internal raw materials can be improved, and the mixing quality and uniformity of the internal raw materials are ensured.

[0019] 2. In the present utility model, the fixing seat is lifted and sleeved on the discharge pipe valve. When the fixing seat is lifted to the bottom so that the metal filter screen fits with the discharge pipe valve, hold the rotary handle and rotate it. When the rotary handle rotates, it drives the threaded rod to rotate through the cooperation of the fixing plate and the threaded groove. When the threaded rod rotates, it drives the clamping plate to clamp on the discharge pipe valve through the cooperation of the limiting rod and the bearing, which can have a detachable impurity removal function. The operation is simple and convenient. It intercepts impurities in the raw materials during discharge, reduces the subsequent screening burden of personnel, and has high practicability.
