Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a production device suitable for phosphorus-containing flame retardants. Background Technology

[0002] With the continuous development of my country's materials industry, flame retardants are widely used in various fields such as chemical materials, electrical appliances, transportation, aerospace, and daily furniture. Generally speaking, flame retardants can be classified according to their elements into phosphorus-based, boron-based, halogen-based, and inorganic metal-based flame retardants. Phosphorus-based flame retardants, also known as phosphorus-containing flame retardants, are a class of high-performance and environmentally friendly flame retardants. They are widely used in flame-retardant treatments of plastics, fibers, coatings, etc.

[0003] The production process of phosphorus-containing flame retardants involves multiple steps, and the current production process has the following problems:

[0004] 1. The processes between adjacent reactors are discontinuous, requiring material transfer between reactors. This transfer is inefficient, and the materials are exposed to air during the transfer process, increasing safety risks and making the equipment highly susceptible to corrosion and damage.

[0005] 2. When the reactor needs to be cleaned, it needs to be completely disassembled, which makes cleaning inconvenient. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a production device suitable for phosphorus-containing flame retardants that can reduce the number of times vacuum pumps are used, alleviate the corrosion of equipment by material exhaust gas, reduce energy consumption, reduce the impact of air on the production reaction process, and ensure the reaction progress.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A production apparatus for phosphorus-containing flame retardants includes several individual components arranged sequentially at intervals. Adjacent individual components include a frame, a reactor body, and a reactor cover that can be fastened to the reactor body.

[0009] The frame is equipped with a lifting structure that can drive the reactor frame to move vertically. The reactor frame is connected to the reactor body through a rotating structure. The reactor frame is equipped with a lid opening and closing assembly.

[0010] The reactor bodies of adjacent single components are respectively set at a high position and a low position, and the reactor bodies at the high position and the low position are arranged alternately. The discharge valve of the reactor body at the high position is connected to the feed valve of the reactor cover at the low position through a feed hose, and the discharge valve of the reactor body at the low position is connected to the feed valve of the reactor cover at the high position through a feed hose. A vacuum pump is installed on the feed hose.

[0011] In this way, by setting up a lifting structure on the frame, the height of the reactor can be adjusted. When cleaning is required, the reactor body moves downwards, the reactor lid moves away from the reactor body, and the rotating structure drives the reactor body to rotate, thus cleaning the inner wall of the reactor. In the production and processing of phosphorus-containing flame retardants, the material is pumped into the reactor located at a higher position using a vacuum pump. Due to the height difference between adjacent reactor bodies, the material is naturally transferred by gravity, which reduces the number of vacuum pumps required, makes it easier to control the feeding speed, and enables continuous production.

[0012] The lifting structure includes four geared motors, which are symmetrically mounted on the frame and located on both sides of the reactor body. The output shaft of each geared motor passes through the frame and is fixedly connected to the upper end of a screw. The lower end of the screw is rotatably connected to the frame. Both ends of the reactor frame have two threaded holes that mate with the screw.

[0013] The rotating structure includes rotating shafts fixedly installed on both sides of the reactor body. The rotating shafts are connected to the reactor frame via bearings. A rotary motor is fixedly installed on the reactor frame, and the output shaft of the rotary motor is fixedly connected to the outer end of the rotating shaft.

[0014] The reactor lid opening and closing assembly includes two cylinder seats fixedly installed on the reactor frame. A cylinder is fixedly installed on the cylinder seat, and a cross arm is fixedly connected to the cylinder rod of the cylinder. The cross arm is fixedly connected to the reactor lid through a connecting block.

[0015] The frame includes a base, and mounting plates are fixed to both sides of the base by columns. The geared motor is fixedly mounted on the mounting plates, and the screw is connected to the base and mounting plates by bearings.

[0016] In summary, this production equipment suitable for phosphorus-containing flame retardants has the advantages of reducing the number of times vacuum pumps are used, mitigating the corrosion of equipment by material exhaust gas, reducing energy consumption, reducing the impact of air on the production reaction process, and ensuring the reaction progress.

[0021] like Figure 1-3 As shown, a production apparatus suitable for phosphorus-containing flame retardants includes several individual components 1, which are arranged sequentially at intervals. Adjacent individual components include a frame, a reactor body 2, and a reactor cover 3 that can be fastened to the reactor body.

[0022] The frame is equipped with a lifting structure that can drive the reactor frame to move vertically. The reactor frame is connected to the reactor body through a rotating structure. The reactor frame is equipped with a lid opening and closing assembly.

[0023] The reactor bodies of adjacent single components are respectively set at a high position and a low position, and the reactor bodies at the high position and the low position are staggered. The discharge valve of the reactor body at the high position is connected to the feed valve of the reactor cover at the low position through the feed hose 4. The discharge valve of the reactor body at the low position is connected to the feed valve of the reactor cover at the high position through the feed hose 5. A vacuum pump 6 is installed on the feed hose.

[0024] In this way, by setting up a lifting structure on the frame, the height of the reactor can be adjusted. When cleaning is required, the reactor body moves downwards, the reactor lid moves away from the reactor body, and the rotating structure drives the reactor body to rotate, thus cleaning the inner wall of the reactor. In the production and processing of phosphorus-containing flame retardants, the material is pumped into the reactor located at a higher position using a vacuum pump. Due to the height difference between adjacent reactor bodies, the material is naturally transferred by gravity, which reduces the number of vacuum pumps required, makes it easier to control the feeding speed, and enables continuous production.

[0025] In implementation, the lifting structure comprises four geared motors 7, symmetrically mounted on the frame and positioned on both sides of the reactor body. The output shafts of the geared motors pass through the frame and are fixedly connected to the upper end of a screw 8. The lower end of the screw is rotatably connected to the frame. Each end of the reactor frame 9 has two threaded holes that mate with the screw. The geared motors drive the screw to rotate, thereby raising and lowering the reactor frame.

[0026] In implementation, the rotating structure includes rotating shafts fixedly installed on both sides of the reactor body. The rotating shafts are connected to the reactor frame via bearings. A rotary motor 10 is fixedly installed on the reactor frame, and the output shaft of the rotary motor is fixedly connected to the outer end of the rotating shafts. The rotary motor drives the reactor body to rotate.

[0027] In practice, the reactor lid opening and closing assembly includes two cylinder seats fixedly mounted on the reactor frame. A cylinder 11 is fixedly mounted on each cylinder seat, and a cross arm 12 is fixedly connected to the cylinder rod of each cylinder. The cross arm is fixedly connected to the reactor lid via a connecting block. The cylinder drives the reactor lid to move.

[0028] In implementation, the frame includes a base 13, with mounting plates 15 fixed to both sides of the base via columns 14. The geared motor is fixedly mounted on the mounting plates, and the screw is connected to the base and mounting plates via bearings. This facilitates manufacturing.

[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
