Description

Technical Field

[0001] The utility model belongs to the technical field of hydroxypropyl methylcellulose production equipment, in particular to a neutralization kettle for hydroxypropyl methylcellulose production. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "a neutralization kettle for the production of hydroxypropyl methylcellulose", and its application number is "CN202123411648.2". This patent mainly allows the gas generated during the neutralization process to automatically flow into the filter box through the air pipe, and the gas is dehumidified and filtered through the cotton fiber adsorption layer, ceramic fiber filter layer and activated carbon adsorption layer in the filter box in turn, and finally the filtered gas is discharged through the exhaust pipe, so that the device has a gas filtration function.

[0003] However, during the stirring process of the neutralization reactor, the stirring rod can only rotate and stir at a fixed position. The components in the reaction liquid cannot be fully mixed in the entire reactor during the stirring process, and areas of different concentrations are easily formed. This fixed-position stirring method makes it difficult to achieve uniform mixing of the reaction liquid in the reactor, thereby affecting the efficiency and yield of the reaction. Utility Model Content

[0004] The utility model aims to provide a neutralization kettle for the production of hydroxypropyl methylcellulose. By providing a stirring mechanism, a slider can slide up and down on two slide bars when rotating, thereby making the stirring more sufficient and improving the efficiency of the neutralization reaction, solving the problem that a stirring method at a fixed position is difficult to achieve uniform mixing of the reaction liquid in the reactor, thereby affecting the efficiency and yield of the reaction.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a neutralization kettle for producing hydroxypropyl methylcellulose, comprising a supporting frame and a reaction kettle, wherein a stirring mechanism and a feeding mechanism are arranged on the reaction kettle, and the stirring mechanism comprises a connecting component and a stirring component;

[0007] The connecting assembly includes a reactor fixedly connected to the inner wall of a supporting frame, a motor fixedly connected to the top surface of the supporting frame, a rotating rod fixedly connected to the output end of the motor, a fixed disc fixedly connected to the rotating rod, the bottom end of the rotating rod is rotatably connected to the inner wall of the reactor, two sliding rods are fixedly connected to the top surface of the fixed disc, a fixed sleeve is fixedly connected to the inner top wall of the reactor, the rotating rod is slidably connected to the inner wall of the fixed sleeve, a sliding block is threadedly connected to the fixed sleeve, the two sliding rods pass through the sliding block, and the sliding rod is slidably connected to the sliding block.

[0008] Furthermore, the stirring assembly includes a plurality of stirring rods fixedly connected to the slider, and a cleaning block is fixedly connected to one end of the plurality of stirring rods away from the slider, and the cleaning block is slidably connected to the inner wall of the reactor.

[0009] Furthermore, the feeding mechanism includes a feeding component, a quantitative component and a synchronization component. The feeding component includes a feeding funnel fixedly connected to the top surface of the reactor. The top surface of the feeding funnel is fixedly connected to an auxiliary material inlet. The feeding funnel is provided with a second valve.

[0010] Furthermore, the quantitative component includes a fixed bracket fixedly connected to the top surface of the feed funnel, a synchronization rod is rotatably connected to the fixed bracket, the bottom end of the synchronization rod extends to the interior of the feed funnel, the bottom end of the synchronization rod is fixedly connected to a connecting rod, and a spiral blade is fixedly connected to the connecting rod.

[0011] Furthermore, the synchronization component includes a first pulley fixedly connected to the synchronization rod, a second pulley fixedly connected to the rotating rod, and a belt is arranged between the first pulley and the second pulley.

[0012] Furthermore, a water inlet pipe is fixedly connected to the top surface of the reactor, a first valve is arranged on the water inlet pipe, and a discharge pipe is fixedly connected to the bottom surface of the reactor.

[0013] The utility model has the following beneficial effects:

[0014] 1. By providing a stirring mechanism, the motor drives the rotating rod to rotate and can drive the slider on the slide rod to rotate, so that the stirring rod on the slider mixes and stirs the materials in the reactor. At the same time, since the fixed sleeve is threadedly connected to the slider, the slider can slide up and down on the two slide rods when rotating, thereby making the stirring more sufficient and improving the efficiency of the neutralization reaction. The stirring rod and the cleaning block cooperate with each other, and while mixing and stirring the materials in the reactor, the inner wall of the reactor can also be cleaned to prevent it from sticking to the inner wall of the reactor.

[0015] 2. By providing a feeding mechanism, the second valve cooperates with the auxiliary material inlet. When alkaline auxiliary materials such as sodium hydroxide are added to the reactor through the feeding funnel for neutralization, the second valve can be used for regulation so that it can be opened or closed at any time. The feeding funnel cooperates with the spiral blade. When the synchronous rod rotates, it drives the spiral blade to rotate through the connecting rod. The inside of the feeding funnel is in contact with the spiral blade. As the spiral blade rotates, it will transport the auxiliary material in the feeding funnel downward. At the same time, the faster the speed of the spiral blade, the stronger its conveying capacity for the auxiliary material. More auxiliary materials can be introduced from the feeding funnel into the reactor for subsequent processing per unit time. The first pulley cooperates with the second pulley. When the motor drives the rotating rod to rotate, it can drive the synchronous rod to rotate synchronously, so that the conveying speed of the auxiliary material can be controlled while stirring. When the conveying speed of the auxiliary material is accelerated, the stirring speed will also be faster, thereby realizing the linkage control of the stirring speed and the auxiliary material conveying speed.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
