UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the problem of uneven force of sealing cover due to the large internal pressure of reaction kettle, the hydraulic cylinder only exerts force on the bottom of sealing cover, leading to uneven force of sealing cover, thus easily causing damage to connecting structure in the process of sealing or opening, thereby reducing service life, and when pressure relief, gas is sprayed too concentratedly, thus easily causing harm to workers, and the safety is low, and a kind of safety pressure relief structure of sizing agent emulsification reaction kettle is provided.

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] A kind of safety pressure relief structure of sizing agent emulsification reaction kettle is designed, including bottom plate and reaction kettle, the bottom plate outer wall upper end is fixedly connected with reaction kettle by multiple struts, the right side upper end of reaction kettle is connected with cross pipe, the cross pipe upper end middle part is connected with first vertical tube, the outer wall right side upper end of reaction kettle is fixedly connected with shell, the outer wall lower end right side of shell is equipped with reaction kettle pressure relief gas dispersion structure, the right side of cross pipe is equipped with reaction kettle pressure relief structure.

[0007] Preferably, the pressure relief structure of the reactor includes a pull rod, the left end of which is rotatably connected to a rubber block via a bearing, a rubber ring is fixedly connected to the left side of the inner wall of the horizontal tube, the outer wall of the rubber block abuts against the rubber ring, a spring is provided at the left end of the outer wall of the pull rod, a first magnetic block is fixedly connected to the outer wall of the pull rod, and a second magnetic block is fixedly connected to the right side of the outer wall of the horizontal tube, with the outer wall of the first magnetic block and the second magnetic block in contact.

[0008] Preferably, the outer wall of the rubber block is sealed to the horizontal tube, and both ends of the spring are fixedly connected to the horizontal tube and the rubber block.

[0009] Preferably, the pressure relief gas dispersion structure of the reactor includes a motor, a first gear is fixedly connected to the end of the output shaft of the motor, the rotating shaft of the first gear is rotatably connected to the outer shell through a bearing, the outer wall of the first gear is meshed with a second gear, a second vertical tube is fixedly connected to the inner wall of the second gear, and a protective cover is fixedly connected to the upper end of the outer wall of the second vertical tube.

[0010] Preferably, the outer wall of the motor is fixedly connected to the outer casing via a bracket, and the inner wall of the second vertical tube is rotatably connected to the first vertical tube via a sealed bearing.

[0011] Preferably, the second vertical tube passes through an opening machined in the middle of the outer casing, and the outer wall of the protective cover is machined with multiple through holes.

[0012] This utility model proposes a safety pressure relief structure for an emulsifying reactor for sizing agents. The beneficial effects are as follows: Through the cooperation of the reactor pressure relief structure and the horizontal tube, rotating the pull rod causes the first magnetic block to disengage from the second magnetic block. During this process, the pull rod can rotate within the rubber via a bearing. After the first magnetic block disengages from the second magnetic block, the limit on the pull rod is removed, and the spring rebounds, causing the pull rod to move to the right and move the rubber block away from the sealing ring. Pushing the pull rod to the left causes the rubber block to abut against the rubber ring. Subsequently, rotating the pull rod causes the first magnetic block to rotate into the interior of the second magnetic block, magnetically fixing the first and second magnetic blocks together. The pull rod drives the rubber block to seal or apply pressure relative to the rubber ring inside the horizontal tube, resulting in a more uniform force distribution. This avoids the problem of uneven force distribution on the sealing cover, which leads to damage and reduced service life, caused by the existing hydraulic cylinder only applying force to the bottom of the sealing cover.

[0013] The gas dispersion structure of the reactor depressurization vessel allows the motor to start and drive the first gear to rotate within the outer casing via a bearing. The rotation of the first gear drives the second gear to rotate, which in turn drives the second vertical pipe to rotate within the first vertical pipe via a sealed bearing. The rotation of the second vertical pipe then drives the protective cover to rotate. By using the motor to drive the protective cover to rotate, the gas ejected from inside the protective cover is dispersed, avoiding the problem of excessively concentrated gas ejection in existing technologies, which could easily cause injury to workers and has low safety.

[0024] A spring 103 is provided on the left end of the outer wall of the pull rod 101.

At the same time, rotating the pull rod 101 to move the first magnetic block 104 away from the second magnetic block 105 can release the magnetic attraction state.

[0025] See attached document Figures 1-5 The pressure relief gas dispersion structure 2 of the reactor includes a motor 201. The motor 201 can meet the working requirements according to actual needs.

[0027] Working principle:

[0028] Depressurization of the sizing agent emulsification reactor:

[0029] First, the raw materials required for emulsifying the sizing agent are fed into the feed port at the top of the reactor 3, and then the emulsification reaction is carried out. After the processing is completed, the sizing agent can be discharged from the discharge port at the lower right end of the reactor 3. In addition, the internal pressure of the reactor 3 needs to be depressurized during the emulsification reaction. When it is necessary to depressurize the internal pressure of the reactor 3, the pull rod 101 is rotated to disengage the first magnetic block 104 from the second magnetic block 105 and release the magnetic attraction state. During this process, the pull rod 101 can rotate within the rubber block 102 through the bearing. After the first magnetic block 104 disengages from the second magnetic block 105, the limit on the pull rod 103 is released. The spring 103 rebounds and drives the pull rod 101 to move to the right and moves the rubber block 102 away from the sealing ring 106. Subsequently, the compressed gas inside the reactor 3 will flow into the horizontal pipe 5, the first vertical pipe 6, the second vertical pipe 204, and the protective cover 205, and be ejected through the multiple through holes processed on the protective cover 205. In this way, the compressed gas inside the reactor 3 can be depressurized.

[0030] Operating procedure of the pressure relief gas dispersion in the sizing agent emulsification reactor:

[0031] When gas is ejected from inside the protective cover 205, the external power supply of the motor 201 is turned on. The motor 201 starts and drives the first gear 202 to rotate in the outer casing 7 through the bearing. The rotation of the first gear 202 drives the second gear 203 to rotate. The rotation of the second gear 203 drives the second vertical tube 204 to rotate in the first vertical tube 6 through the sealed bearing. The rotation of the second vertical tube 204 drives the protective cover 205 to rotate. In this way, the air ejected from inside the protective cover 205 can be sprayed out in a circumferential manner to disperse the gas and avoid the ejected gas being too concentrated and causing harm to the staff.

[0032] Sealing operation of the sizing agent emulsification reactor:

[0033] After the pressure inside the reactor 3 is released, push the lever 101 to the left to make the rubber block 102 abut against the rubber ring 106. Then rotate the lever 101 to make the first magnetic block 104 rotate into the second magnetic block 105, so that the first magnetic block 104 and the second magnetic block 105 are magnetically attracted and fixed. In this way, the lever 101 can be limited, thereby achieving the sealing work.
