Description

Technical Field

[0001] This application relates to the field of styrene-butadiene latex production technology, and in particular to an internal defoamer for degassing styrene-butadiene latex. Background Technology

[0002] Styrene-butadiene latex is a commonly used synthetic latex widely applied in various industries. It is an emulsion copolymerized from butadiene and styrene, possessing excellent physical and chemical properties. During the processing and production of styrene-butadiene latex, because the liquid contains air, a defoamer is required to eliminate the air bubbles within the latex.

[0003] The published patent with authorization announcement number CN221107088U relates to the technical field of styrene-butadiene latex production, and in particular to a styrene-butadiene latex bubble eliminator. This device facilitates the cleaning of components inside the degassing cylinder, preventing waste caused by latex adhesion and improving bubble elimination quality. It includes a degassing cylinder and a discharge pipe, with the discharge pipe connected to the middle of the bottom end of the degassing cylinder. It also includes an air pump, an air extraction pipe, a sealing mechanism, a scraping mechanism, a defoaming mechanism, a vibration mechanism, and a support mechanism. The sealing mechanism is installed at the top of the degassing cylinder. The air pump is fixedly installed at the top rear end of the sealing mechanism, with its input end connected to the air extraction pipe. The input end of the air extraction pipe passes through the sealing mechanism and communicates with the interior of the degassing cylinder. The scraping mechanism is installed at the bottom of the sealing mechanism and inside the degassing cylinder. The defoaming mechanism is installed at the middle of the bottom end of the sealing mechanism. The vibration mechanism is installed at both ends of the bottom of the degassing cylinder. The support mechanism is installed at the bottom of the degassing cylinder to support the equipment.

[0004] When the above device is implemented, the drive motor drives the rotating shaft to rotate, and the piercing rod on the surface of the stirring rod pierces the air bubbles in the material. However, the existing defoamer in the degassing kettle for styrene-butadiene latex cannot adjust the height of the rotating shaft, which limits the stirring range of the piercing rod. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an internal defoamer for degassing styrene-butadiene latex, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: an internal defoamer for degassing styrene-butadiene latex, comprising a degassing tank, a sealing mechanism at the top of the degassing tank, a sealing cover at the top of the sealing mechanism, the sealing cover being slidably connected to the degassing tank, a feed pipe fixedly connected to the top of the sealing cover, a rotating mechanism on one side of the feed pipe, a height adjustment mechanism on one side of the rotating mechanism, the height adjustment mechanism comprising a second motor, the second motor being fixedly connected to the sealing cover, a threaded rod fixedly connected to the output end of the second motor, a moving rod threadedly connected to the outside of the threaded rod, a fixed rod slidably connected to the outside of the moving rod, the fixed rod being fixedly connected to the sealing cover, a rotating rod rotatably connected to the bottom of the moving rod, a stirring rod slidably connected to one side of the rotating rod, a connecting mechanism between the stirring rod and the rotating rod, a positioning mechanism at the connection between the degassing tank and the sealing cover, and a vibration mechanism on the surface of the degassing tank.

[0007] In a preferred embodiment, the bottom of the degassing tank is fixedly connected to three support legs, which are arranged in a ring at the bottom of the degassing tank.

[0008] By adopting the above technical solution, with the three support legs arranged in a ring at the bottom of the degassing tank, the degassing tank can be better supported.

[0009] In a preferred embodiment, the bottom of the degassing tank is funnel-shaped, a discharge pipe is fixedly connected to the bottom of the degassing tank, and a valve is fixedly connected to the outside of the discharge pipe.

[0010] By adopting the above technical solution, the bottom of the degassing tank is funnel-shaped, and the material inside the degassing tank is discharged through the discharge pipe. The opening and closing of the discharge pipe is controlled by a valve, which can better discharge the material inside the degassing tank.

[0011] In a preferred embodiment, the sealing mechanism includes a groove formed on the surface of the degassing tank, and a circular rubber sealing strip is provided inside the groove.

[0012] By adopting the above technical solution, the rubber sealing strip is limited by the groove, and then the rubber sealing strip abuts against the surface of the sealing cover to seal between the rubber sealing strip and the degassing tank, which can better seal the degassing tank.

[0013] In a preferred embodiment, the rotating mechanism includes a first motor, which is fixedly connected to the sealing cover. A drive gear is fixedly connected to the output end of the first motor. A driven gear meshes with one side of the drive gear. The driven gear is rotatably connected to the sealing cover. A sleeve rod is fixedly connected to the bottom of the driven gear. A support rod is slidably connected inside the sleeve rod. The end of the support rod away from the sealing cover is fixedly connected to the rotating rod.

[0014] By adopting the above technical solution, the output end of the first motor rotates to drive the drive gear to rotate, which in turn drives the driven gear to rotate, which in turn drives the sleeve rod to rotate, which in turn drives the support rod to rotate, which in turn drives the rotating rod to rotate, and the stirring rod on the surface of the rotating rod stirs the material, thus achieving better stirring of the material.

[0015] In a preferred embodiment, the connecting mechanism includes an insertion block, which is fixedly connected to a stirring rod. A second spring is fixedly connected inside the insertion block, and a positioning block is fixedly connected to one side of the second spring. The positioning block is slidably connected to the insertion block.

[0016] By adopting the above technical solution, the rotating rod and the stirring rod are connected by inserting the insertion block on the surface of the stirring rod into the interior of the rotating rod. The second spring supports the positioning block, and the positioning block limits the insertion block. When the stirring rod needs to be disassembled, the positioning block is pressed to make the positioning block enter the interior of the insertion block, and then the insertion block is pulled to make the insertion block detach from the surface of the rotating rod, which can better disassemble the insertion block.

[0017] In a preferred embodiment, the positioning mechanism includes a positioning frame, which is fixedly connected to the degassing tank. A positioning rod is slidably connected inside the positioning frame, and a first spring is sleeved on the outside of the positioning rod.

[0018] By adopting the above technical solution, the positioning rod is limited by the positioning frame, supported by the first spring, and then inserted into the inside of the sealing cover to position the sealing cover, which can better position the sealing cover.

[0019] In a preferred embodiment, the vibration mechanism includes a mounting frame, which is fixedly connected to the degassing tank. A third motor is fixedly connected inside the mounting frame, and an eccentric block is fixedly connected to the output end of the third motor.

[0020] By adopting the above technical solution, the third motor is fixed by the mounting bracket, and the output end of the third motor rotates to drive the eccentric block to rotate. The rotation of the eccentric block drives the degassing tank to vibrate, and the vibration of the degassing tank causes the air bubbles in the material to float to the surface, which can better make the air bubbles in the material float to the surface.

[0021] Beneficial effects of this application:

[0022] 1. This defoamer for degassing styrene-butadiene latex utilizes a second motor, a threaded rod, a fixed rod, and a moving rod. The output of the second motor rotates the threaded rod, which in turn limits the movement of the moving rod. The rotation of the threaded rod then causes the moving rod to slide within the fixed rod, which in turn pushes the rotating rod to move. This movement of the rotating rod then moves the agitating rod, increasing the stirring range of the agitating rod. This design avoids the problem of existing defoamers for degassing styrene-butadiene latex lacking adjustable shaft height, thus improving practicality.

[0023] 2. This defoamer for degassing styrene-butadiene latex uses an insert block, a positioning block, and a second spring. The insert block, located on the surface of the stirring rod, is inserted into the interior of the rotating rod to connect the rotating rod and the stirring rod. The second spring supports the positioning block, which in turn limits the position of the insert block. When the stirring rod needs to be disassembled, pressing the positioning block causes it to enter the interior of the insert block, and pulling the insert block disengages it from the surface of the rotating rod. This design avoids the problem of existing defoamers for degassing styrene-butadiene latex that prevent disassembly of the stirring rod, thus improving practicality. Attached Figure Description
