Description

Technical Field

[0001] The invention relates to the technical field of polyethylene polyamine production, in particular to a reaction device for polyethylene polyamine production. Background Art

[0002] Polyethylene polyamines are a type of ethyleneamines, including linear homologues, branched or cyclic amines of ethylenediamine. Among them, common linear polyethylene polyamines include diethylenetriamine, triethylenetetramine (straight chain), tetraethylenepentamine (straight chain), etc., which are widely used in papermaking, lubricant additives, chelating agents, curing agents and other fields. In recent years, my country's ethylenediamine market has gradually become saturated, but the production capacity of linear polyethylene polyamines is still low, and high-quality products rely on imports, which restricts the development of downstream industries. With the continuous maturity of the domestic chemical industry and the gradual optimization of the industrial structure, the market demand for high-purity linear polyethylene polyamine products is increasing.

[0003] During the mixing process, uneven stirring can easily lead to unstable product quality and cause problems such as stratification and agglomeration. Polyethylene polyamines have high viscosity and reactivity, requiring mixing equipment to be able to fully and evenly mix the raw materials to ensure the completeness of the reaction and the consistency of the product; the mixing time is long. Due to equipment design defects and low stirring efficiency, traditional equipment often takes a long time to achieve the expected mixing effect, resulting in an extension of the production cycle and affecting overall production efficiency; the operation is complicated. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented by the following technical solutions: A reaction device for producing polyethylene polyamines, comprising a tank body, a bottom edge of the tank body is fixedly connected with a support, the number of the support is three, the three support pillars are evenly distributed at the bottom of the tank body, a feed pipe is fixedly connected at the middle of the bottom of the tank body, and a heating pipe is arranged inside the tank body;

[0005] A fixing part, the fixing part is fixedly installed on the top of the tank body, a feed pipe is fixedly connected to the top of the fixing part, a frame is fixedly connected to the middle of the top of the fixing part, and a motor is fixedly connected to the top of the frame;

[0006] A connecting piece, which is fixedly mounted on the output end of the motor and is located inside the frame;

[0007] A stirring component, the stirring component is arranged inside the tank body;

[0008] Among them, the stirring component includes a rotating shaft, which is fixedly connected to the connecting piece. The rotating shaft is located inside the tank body, and the rotating shaft passes through the fixing piece and extends to the inside of the frame body. The raw materials are added to the inside of the tank body through the feeding pipe. The motor is connected to an external power supply to work, and the motor drives the rotating shaft to rotate, so that the rotating shaft drives the fixing seat and the rotating plate to rotate, and the rotating shaft drives the L-shaped plate to rotate. The rotating plate and the L-shaped plate work together to stir and mix the raw materials inside the tank body, so that different reactants in the raw materials can be fully contacted and evenly distributed, avoiding the situation where the local concentration is too high or too low, ensuring that the reaction can be carried out evenly in all parts, thereby improving the quality and stability of the product, and at the same time, achieving uniform mixing and reaction of materials in a shorter time, reducing stirring time and energy consumption. The bottom of the rotating shaft is fixedly connected with a fixing ring, and a slide groove is provided on the outside of the fixing ring. The inside of the slide groove is slidably connected with an L-shaped plate, the outside of the rotating shaft is fixedly connected with a fixing seat, and the side of the L-shaped plate close to the fixing seat is fixedly connected with an inclined plate, and the outside of the fixing seat is fixedly connected with a rotating plate.

[0009] Preferably, there are two slide grooves, which are symmetrically arranged with the rotating shaft as the center, and the side of the L-shaped plate away from the fixed ring contacts the inside of the tank body. A circular groove is opened at one end of the L-shaped plate away from the fixed ring. When the motor is connected to an external power supply, the motor drives the rotating shaft to rotate, and the rotating shaft drives the L-shaped plate to rotate. Utilizing the mutual cooperation between the circular groove and the spiral convex ring, as the rotating shaft rotates, the L-shaped plate reciprocates up and down along the spiral convex ring inside the slide groove, so that the L-shaped plate drives the inclined plate to move up and down. Under the push of the inclined plate, the raw materials at the edge of the tank body move toward the middle, and the rotating plate rotates to push the raw materials in the middle outward. At this time, the raw materials inside the tank body form a circular reflux from outside to inside to outside, ensuring sufficient contact and mixing between the raw materials and improving the reaction efficiency. The circular grooves are evenly arranged on the side of the L-shaped plate. There are two fixed seats, and the fixed seats and the inclined plates are alternately arranged.

[0010] Preferably, the tank body includes an outer shell, an inner tank body is arranged inside the outer shell, a spiral convex ring is fixedly connected to the inner wall of the inner tank body, the heating tube is located inside the spiral convex ring, and the heating tube is located inside the gap between the outer shell and the inner tank body, an extension tube is fixedly connected to the middle of the bottom of the inner tank body, the extension tube is fixedly connected to the feeding tube, and the spiral convex ring is located inside the circular groove.

[0011] Preferably, the fixing member includes a top cover, which is fixedly connected to the top of the shell, a sealing ring is fixedly connected to the middle of the top of the top cover, the sealing ring is sleeved on the outside of the rotating shaft, an air outlet pipe is fixedly connected to the top of the top cover, the air outlet pipe is located on the side away from the feed pipe, a sliding cylinder is slidably connected to the outside of the air outlet pipe, a fixing rod is fixedly connected to the inside of the air outlet pipe, a circular plate is arranged on the outside of the fixing rod, and the circular plate is made of rubber. During the exhaust process, the circular plate is deformed under the action of the internal air pressure of the tank body, and the circular plate is in close contact with the outer side of the U-shaped cylinder to prevent the circular plate from excessive deformation. Since foam may be generated during the reaction and stirring process, These bubbles may flow out of the air outlet pipe together with the reaction liquid. By setting the circular plate, the deformed circular plate is like a barrier. When the bubbles and liquid hit the circular plate, they will be blocked and flow back into the tank body. The middle part of the circular plate is fixedly connected to the middle part of the fixed rod. A spiral groove is opened inside the air outlet pipe. The inner wall of the air outlet pipe is fixedly connected to a limiting ring. The limiting ring is set as a T-shaped ring. A U-shaped cylinder is set on the side of the air outlet pipe close to the limiting ring. A cylinder is fixedly connected to the inner wall of the opening of the U-shaped cylinder. The end of the cylinder away from the U-shaped cylinder is fixedly connected to the limiting ring. A ball is slidably connected to the inside of the U-shaped cylinder. During the reaction process of the tank body, In the state of high temperature and high pressure, when the internal air pressure of the tank is too high, the circular plate is deformed by force, and the circular plate is in close contact with the outer side of the U-shaped cylinder to prevent the circular plate from excessive deformation. At this time, the high-pressure gas inside the tank enters the interior of the outlet pipe along the gap between the outlet pipe and the circular plate, and the high-pressure gas flows along the spiral groove on the inner wall of the outlet pipe. By setting the spiral groove, the flow path of the high-pressure gas is lengthened, thereby reducing the sudden change of the flow velocity, thereby reducing the noise caused by the fluctuation of the gas flow velocity. The high-pressure gas enters the interior of the U-shaped cylinder along the limit ring, exerts force on the ball, and makes the ball move toward the bottom of the U-shaped cylinder. Thereby, the ball drives the sliding cylinder to slide on the outlet pipe, so that the through hole on the sliding cylinder overlaps with the connecting hole on the outlet pipe. At this time, the high-pressure gas passes through the gap between the ball and the limiting ring, and is then discharged from the connecting hole and the through hole. When the internal air pressure returns to the normal range, under the elastic force of the spring plate, the ball and the sliding cylinder are reset and the exhaust stops. A round rod is fixedly connected to the side of the ball close to the sliding cylinder, the round rod is fixedly connected to the middle part of the interior of the sliding cylinder, and a spring plate is fixedly connected to the outside of the round rod. The end of the spring plate away from the round rod is fixedly connected to the limiting ring. A through hole is provided on the outside of the sliding cylinder, and a connecting hole is provided on the outside of the outlet pipe close to the sliding cylinder.

[0012] Preferably, the connecting member includes a fixed block, which is fixedly connected to the top of the rotating shaft, a gasket is fixedly installed on the side of the fixed block away from the rotating shaft, the gasket is elastic, an intermediate block is fixedly installed on the outside of the gasket, the gasket is symmetrically arranged with the intermediate block as the center, a convex block is fixedly connected to the middle of the fixed block, the convex and concave of the convex are adapted to the intermediate block, a contact rod is fixedly connected to the outer edge of the fixed block, a limiting rod is provided on the top of the contact rod, and the contact surface between the limiting rod and the contact rod is inclined. During the stirring process, the load of the rotating shaft may fluctuate due to factors such as the unevenness of the material and the change of the stirring speed. By providing a gasket and utilizing the elastic properties of the gasket, these impacts can be effectively buffered to prevent them from being directly transmitted to driving equipment such as the motor. At the same time, during vibration, a relative displacement occurs between the contact rod and the limiting rod, and the inclined contact is utilized to avoid slipping of the connecting member. A positioning block is fixedly connected to the end of the limiting rod away from the contact rod, and the positioning block is fixedly connected to the output end of the motor.

[0013] The present invention provides a reaction device for producing polyethylene polyamines, which has the following beneficial effects:

[0014] 1. The reaction device for producing polyethylene polyamines stirs and mixes the raw materials in the tank body by working together with the rotating plate and the L-shaped plate, so that different reactants in the raw materials can be fully contacted and evenly distributed, avoiding the situation of excessively high or low local concentrations, ensuring that the reaction can be carried out evenly in all parts, thereby improving the quality and stability of the product.

[0015] 2. In the reaction device for producing polyethylene polyamines, the raw materials at the edge of the tank body move toward the middle under the push of the inclined plate, and the rotating plate rotates to push the raw materials in the middle outward. At this time, the raw materials inside the tank body form a circular reflux from outside to inside and then to outside, ensuring full contact and mixing between the raw materials and improving the reaction efficiency.

[0016] 3. The reaction device for producing polyethylene polyamines has a spiral groove, which makes the flow path of the high-pressure gas longer, thereby reducing the sudden change of the flow rate and reducing the noise caused by the fluctuation of the gas flow rate.

[0017] Fourth, the reaction device for producing polyethylene polyamines can effectively buffer these impacts by arranging gaskets and utilizing the elastic properties of the gaskets to prevent them from being directly transmitted to driving devices such as motors. At the same time, when vibrating, relative displacement occurs between the contact rod and the limit rod, and inclined contact is utilized to avoid slipping of the connecting parts.

The side of the L-shaped plate 74 away from the fixing ring 72 contacts the inside of the tank body 1, and a circular groove 75 is provided at one end of the L-shaped plate 74 away from the fixing ring 72. When the motor 4 is connected to an external power supply and works, the motor 4 drives the rotating shaft 71 to rotate, and the rotating shaft 71 drives the L-shaped plate 74 to rotate. By utilizing the mutual cooperation between the circular groove 75 and the spiral convex ring 13, as the rotating shaft 71 rotates, the L-shaped plate 74 moves along the spiral convex ring 13 in the slide groove 73. The interior of the tank body 1 reciprocates up and down, so that the L-shaped plate 74 drives the inclined plate 78 to move up and down. Under the push of the inclined plate 78, the raw materials at the edge of the tank body 1 move toward the middle, and the rotating plate 77 rotates to push the raw materials in the middle outward. At this time, the raw materials inside the tank body 1 form a circular reflux from outside to inside and outside to ensure full contact and mixing between the raw materials and improve the reaction efficiency. The circular grooves 75 are evenly arranged on the side of the L-shaped plate 74. There are two fixed seats 76, and the fixed seats 76 and the inclined plates 78 are alternately arranged.

[0036] The third embodiment is based on the first and second embodiments. Figure 6 to Figure 7As shown, the fixing member 3 includes a top cover 31, which is fixedly connected to the top of the shell 11, a sealing ring 32 is fixedly connected to the middle of the top of the top cover 31, and the sealing ring 32 is sleeved on the outside of the rotating shaft 71. An air outlet pipe 33 is fixedly connected to the top of the top cover 31, and the air outlet pipe 33 is located on the side away from the feed pipe 9. A sliding cylinder 34 is slidably connected to the outside of the air outlet pipe 33, and a fixing rod 311 is fixedly connected to the inside of the air outlet pipe 33. A circular plate 312 is arranged on the outside of the fixing rod 311. The circular plate 312 is made of rubber. During the exhaust process, the circular plate 312 is deformed under the action of the internal air pressure of the tank body, and the circular plate 312 is in close contact with the outside of the U-shaped cylinder 36 to prevent the circular plate 312 from excessive deformation. The foam may flow out of the gas outlet pipe 33 together with the reaction liquid by setting the circular plate 312. The deformed circular plate 312 is like a barrier. When the foam and liquid hit the circular plate 312, they will be blocked and flow back into the tank body 1. The middle part of the circular plate 312 is fixedly connected to the middle part of the fixing rod 311. A spiral groove 35 is provided inside the gas outlet pipe 33.

A cylinder 37 is fixedly connected to the inner wall of the opening of the U-shaped cylinder 36. The end of the cylinder 37 away from the U-shaped cylinder 36 is fixedly connected to the limiting ring 38. A ball 39 is slidably connected to the inside of the U-shaped cylinder 36. During the reaction of the tank body 1, the tank body 1 is in a state of high temperature and high pressure. When the internal air pressure of the tank body 1 is too high, the circular plate 312 is deformed by force. The circular plate 312 is in close contact with the outer side of the U-shaped cylinder 36 to prevent the circular plate 312 from being excessively deformed. At this time, the high-pressure gas inside the tank body 1 enters the interior of the gas outlet pipe 33 along the gap between the gas outlet pipe 33 and the circular plate 312. The high-pressure gas flows along the spiral groove 35 on the inner wall of the gas outlet pipe 33. By setting the spiral groove 35, the flow path of the high-pressure gas is lengthened, thereby reducing the sudden change of the flow velocity, thereby reducing the noise caused by the fluctuation of the gas flow velocity. The high-pressure gas enters the interior of the U-shaped cylinder 36 along the limit ring 38, exerting force on the ball 39, so that the ball 39 moves toward the bottom of the U-shaped cylinder 36, thereby The ball 39 drives the sliding cylinder 34 to slide on the outlet pipe 33, so that the through hole 314 on the sliding cylinder 34 overlaps with the connecting hole 315 on the outlet pipe 33. At this time, the high-pressure gas passes through the gap between the ball 39 and the limiting ring 38, and then is discharged from the connecting hole 315 and the through hole 314. When the internal air pressure returns to the normal range, under the elastic force of the spring plate 310, the ball 39 and the sliding cylinder 34 are reset and the exhaust stops.

During the stirring process, the load of the rotating shaft 71 may fluctuate due to factors such as the unevenness of the material and the change in the stirring speed. By setting a gasket 82 and utilizing the elastic properties of the gasket 82, these impacts can be effectively buffered to prevent them from being directly transmitted to the driving equipment such as the motor 4. At the same time, during vibration, a relative displacement occurs between the contact rod 85 and the limit rod 86. The inclined contact is utilized to prevent the connecting member 8 from slipping. The end of the limit rod 86 away from the contact rod 85 is fixedly connected to a positioning block 84, and the positioning block 84 is fixedly connected to the output end of the motor 4.

[0038] When in use, the raw materials are added into the interior of the tank body 1 through the feed pipe 9, and the motor 4 is connected to an external power supply to work. The motor 4 drives the rotating shaft 71 to rotate, so that the rotating shaft 71 drives the fixing seat 76 and the rotating plate 77 to rotate, and the rotating shaft 71 drives the L-shaped plate 74 to rotate. By utilizing the mutual cooperation between the circular groove 75 and the spiral convex ring 13, as the rotating shaft 71 rotates, the L-shaped plate 74 reciprocates up and down inside the slide groove 73 along the spiral convex ring 13, so that the L-shaped plate 74 drives the inclined plate 78 to move up and down. Under the push of the inclined plate 78, the raw materials at the edge of the tank body 1 move toward the middle, and the rotating plate 77 rotates to push the raw materials in the middle outward.

When the internal air pressure of the tank body 1 is too high, the circular plate 312 is deformed by force, and the circular plate 312 is in close contact with the outer side of the U-shaped cylinder 36 to prevent the circular plate 312 from excessively deforming. At this time, the high-pressure gas inside the tank body 1 enters the inside of the outlet pipe 33 along the gap between the outlet pipe 33 and the circular plate 312, and the high-pressure gas flows along the spiral groove 35 on the inner wall of the outlet pipe 33. By setting the spiral groove 35, the flow path of the high-pressure gas is lengthened, thereby reducing the sudden change of the flow velocity, thereby reducing the noise generated by the fluctuation of the gas flow velocity. The high-pressure gas enters the interior of the U-shaped cylinder 36 along the limiting ring 38, exerts force on the ball 39, causing the ball 39 to move toward the bottom of the U-shaped cylinder 36, so that the ball 39 drives the sliding cylinder 34 to slide on the outlet pipe 33, so that the through hole 314 on the sliding cylinder 34 overlaps with the connecting hole 315 on the outlet pipe 33. At this time, the high-pressure gas passes through the gap between the ball 39 and the limiting ring 38, and is then discharged from the connecting hole 315 and the through hole 314.
