Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production, and specifically relates to an environmentally friendly block silicone oil reactor. Background Art

[0002] Block silicone oil is a special reactive polymer that can be easily applied to various fiber yarns and fabrics, giving the yarns and fabrics drape, resilience, and an ultra-loose, ultra-soft, and ultra-smooth feel. It does not stick to the hands after drying and is resistant to water washing and dry cleaning.

[0003] However, in the process of producing block silicone oil, the existing block silicone oil reactor usually introduces inert gas to protect the reaction. At the same time, some harmful acidic gases are generated during the reaction. These gases are often discharged through the exhaust pipe, thereby polluting the environment and endangering human health. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the current block silicone oil reactor described in the above background technology will discharge waste gas and is not environmentally friendly and safe. A new environmentally friendly block silicone oil reactor is proposed, which can absorb waste gas and recycle inert gas.

[0005] The technical solution adopted to achieve the above purpose is an environmentally friendly block silicone oil reactor, which comprises:

[0006] A cylinder, an air inlet chamber is arranged above the cylinder, a discharge pipe and a plurality of supporting legs are arranged at the bottom of the cylinder, an inert gas inlet pipe is arranged on the side wall of the air inlet chamber, an exhaust pipe is arranged on the top of the cylinder, a cavity is opened on the side wall of the cylinder, and a heating pipe is arranged in the cavity;

[0007] A stirring unit, the stirring unit comprises a motor, a rotating shaft, a plurality of stirring components and a first stirring part, the motor is fixed above the air inlet chamber, one end of the rotating shaft is connected to the motor, the other end of the rotating shaft penetrates the air inlet chamber and the top wall of the cylinder and extends into the cylinder, the rotating shaft is a hollow structure, an air inlet is provided at the position of the rotating shaft located in the air inlet chamber, the stirring components are fixed around the rotating shaft, and the first stirring part is fixed at the bottom of the rotating shaft;

[0008] The waste gas treatment unit comprises an alkali liquid tank, a return air pipe is arranged on the top of the alkali liquid tank, the return air pipe is connected with the air inlet chamber, and the exhaust pipe is connected with the alkali liquid tank.

[0009] In the above technical scheme, the inert gas introduced from the inert gas inlet pipe plays a protective role in the material reaction in the reactor. The gas enters the air inlet chamber and then enters the rotating shaft through the air inlet port, then enters the stirring assembly from the rotating shaft, and is discharged from the stirring assembly. The gas then drives the material to move and mix, and waste gas is generated during the reaction. The inert gas drives the waste gas to be discharged from the exhaust pipe into the alkali liquid tank, so that the waste gas is absorbed. The inert gas then returns to the cylinder from the return pipe for circulation, which not only removes the waste gas but also recycles the inert gas.

[0010] Furthermore, the stirring assembly includes a connecting tube, a stirring block, a stirring rod and a scraper. The connecting tube and the stirring block are hollow structures. The connecting tube connects the stirring block and the rotating shaft. One end of the stirring rod is fixedly connected to the stirring block (402), and the other end of the stirring rod is fixedly connected to the scraper.

[0011] Furthermore, at least one side wall of the stirring block is provided with air holes.

[0012] In the above technical solution, the stirring assembly is connected to the rotating shaft, so that inert gas can enter it and then be discharged from the pores of the stirring block in the form of bubbles, driving the flow of materials; the connecting pipe, stirring block, stirring rod and scraper can all drive the flow of materials and promote uniform mixing of materials.

[0013] Furthermore, the scraper blade is in contact with the inner wall of the cylinder.

[0014] In the above technical solution, since the side wall of the cylinder will heat the material, the material close to the inner wall of the cylinder may adhere to the side wall. While the rotating shaft drives the stirring assembly to rotate, it can also drive the scraper to scrape the inner wall of the cylinder.

[0015] Furthermore, the exhaust pipe extends into the interior of the alkali liquid tank, and the pipe opening of the exhaust pipe located inside the alkali liquid tank is close to the bottom wall of the alkali liquid tank.

[0016] In the above technical solution, it can be ensured that the waste gas is discharged and rises from the bottom of the alkali liquid tank, so that the alkali liquid can fully absorb the waste gas.

[0017] Furthermore, the first stirring part includes a plurality of connecting rods and a plurality of arc-shaped rods, one end of the connecting rod is fixedly connected to the rotating shaft, and the other end of the connecting rod is fixedly connected to the arc-shaped rod.

[0018] Furthermore, the connecting rod is arranged to be inclined downward.

[0019] In the above technical solution, the materials are stirred and mixed by the connecting rods arranged to be inclined downward, and the arc-shaped rods are arranged to prevent the materials from being deposited at the bottom of the cylinder.

[0020] Furthermore, the stirring unit also includes a plurality of second stirring parts, and the second stirring parts are arranged on the circumference of the rotating shaft.

[0021] Furthermore, the second stirring part and the stirring assembly are interspersed.

[0022] In the above technical solution, the second stirring part is in the shape of a spiral blade and is arranged between the stirring components to supplement the mixing effect of the stirring components to make the materials mixed more evenly.

[0023] Furthermore, a sealing ring is provided at the location where the rotating shaft passes through the air inlet chamber and the cylinder.

[0024] In the above technical solution, a sealing ring is provided to prevent the inert gas from leaking from the air inlet chamber.

[0025] The advantages of the utility model are:

[0026] 1. The utility model fills inert gas from the air inlet chamber and then discharges it through the rotating shaft and the air holes on the stirring assembly connected to the rotating shaft. The inert gas drives the material to move in the form of bubbles, thereby promoting uniform mixing of the materials.

[0027] 2. The utility model uses inert gas to carry out waste gas and then enter the alkali liquid tank to absorb the waste gas, and then re-introduces the inert gas into the air intake chamber for gas circulation, effectively utilizing the inert gas and reducing production consumption.
