Description

Technical Field

[0001] This invention relates to the field of copolyol processing technology, specifically to a processing equipment and method for preparing copolyols. Background Technology

[0002] In the preparation of copolyols, the raw materials need to be stirred and mixed first. Existing processing equipment for preparing copolyols usually only has a stirring shaft to stir the raw materials inside the stirring tank. In order to enhance the stirring effect, the stirring shaft is usually enlarged to fit the inner wall. This results in limited space for the raw materials. When the stirring shaft is small, the stirring range is limited, and the raw materials tend to rotate in a designated position for a long time, resulting in poor stirring effect. Alternatively, it is necessary to stop the machine, wait for the raw materials to settle, and then repeat the stirring process multiple times to improve the stirring effect. Therefore, this invention proposes a processing equipment and method for preparing copolyols. Summary of the Invention

[0003] (a) Technical problems to be solved

A vertical seat is fixedly connected to the left side of the top of the intermediate plate, and a vertical plate is fixedly connected to the right side of the top of the intermediate plate. Two horizontal bars are fixedly connected between the vertical seat and the vertical plate. A sliding seat is slidably connected between the outer surfaces of the two horizontal bars. A first motor is fixedly connected to the bottom of the sliding seat. A stirring shaft is fixedly connected to the bottom end of the first motor via a coupling. A stirring cylinder is provided above the intermediate plate, wherein the stirring shaft is located inside the stirring cylinder. A groove is provided on one side of the vertical seat, and a connecting device is provided within the groove. The connecting device drives the sliding seat to move horizontally left and right, and drives the stirring cylinder to move vertically up and down.

[0007] As an improved technical solution, the connecting device includes a hydraulic rod fixedly connected to the top of the inner wall of the groove, an intermediate block fixedly connected to the bottom end of the hydraulic rod, a connecting plate rotatably connected to one side of the intermediate block, a traction seat rotatably connected to one side of the connecting plate, and one side of the traction seat fixedly connected to one side of the sliding seat.

[0008] As an improved technical solution, a pull rope is fixedly connected to the bottom of the intermediate block, a first fixed pulley is fixedly connected to the lower inner wall of the groove, a second fixed pulley is fixedly connected to the bottom of the intermediate plate, the pull rope turns sequentially through the first and second fixed pulleys, and one end of the pull rope is fixedly connected to the bottom of the mixing drum.

[0009] As an improved technical solution, a first spring rod is fixedly connected to both sides of the bottom of the stirring drum, and the bottom ends of the two first spring rods are fixedly connected to the top of the intermediate plate. An oblique hole is opened on the top of the intermediate plate, and a vertical hole is opened on the top of the intermediate plate and on one side of the oblique hole. The pull rope passes through the oblique hole and the vertical hole.

[0010] As an improved technical solution, extension plates are fixedly connected to both sides of the top of the base plate, and positioning rods are rotatably connected between the two extension plates. The opposite ends of the two positioning rods are fixedly connected to both sides of the middle plate. Second spring rods are fixedly connected to both sides of the top of the base plate, and the top ends of the two second spring rods are in contact with the bottom of the middle plate.

[0011] As an improved technical solution, a second motor is fixedly connected to the top of the base plate, a rotating shaft is fixedly connected to one end of the output shaft of the second motor, and a mounting base is fixedly connected to the top of the base plate and to one side of the second motor. One end of the rotating shaft passes through the mounting base and extends to the outside of the mounting base.

[0012] As an improved technical solution, a cam is fixedly connected to the outer surface of the rotating shaft, a connecting rod is fixedly connected to the surface of the cam, a rotating sleeve is rotatably connected to the outer surface of the connecting rod, a control rod is rotatably connected to one side of the rotating sleeve, and one end of the control rod is fixedly connected to one side of the intermediate plate.

[0014] This invention also discloses a processing method for a processing apparatus for preparing copolyols, specifically including the following steps:

[0015] S1: First, place the copolyol raw material in the mixing drum, then start the first motor to drive the stirring shaft to rotate. The rotating stirring shaft mixes and stirs the copolyol raw material. Then start the hydraulic rod to drive the middle block to move downward. During the downward movement of the middle block, the connecting plate rotates and pulls the traction seat. Under the action of the traction seat, the sliding seat slides to one side. During the reverse operation of the hydraulic rod, the sliding seat is pushed back to its original position. The stirring shaft swings left and right in the mixing drum, which can pull the pull rope synchronously. Under the action of the pull rope, the mixing drum moves downward and rebounds to the initial position under the action of the first spring rod.

[0016] S2: Then start the second motor. Under the action of the second motor, the rotating shaft will rotate. The rotation of the rotating shaft will cause the cam to rotate. The rotation of the cam will then cause the connecting rod to rotate. At this time, the connecting rod will drive the rotating sleeve to rotate. Then, through the control rod, the middle plate will rotate slightly along the positioning rod, so that the middle plate can swing back and forth slightly.

[0017] As an improved technical solution, the forward and reverse motion paths of the hydraulic rod are controlled by an external PLC programming program, and the forward and reverse motion paths are the same distance.

[0018] (III) Beneficial Effects

[0019] This invention provides a processing apparatus and method for preparing copolyols. Compared with the prior art, it has the following advantages:

[0020] (1) The processing equipment and method for preparing copolyols, by providing a connecting device in the groove, uses the connecting device to drive the sliding seat to move left and right and drive the stirring drum to move up and down. Based on the existing stirring by the stirring shaft, the stirring shaft can be moved, and a larger stirring range can be achieved with a smaller stirring shaft. At the same time, the depth of the stirring drum will also change in real time. When the raw material of the copolyol is in the stirring drum, the stirring position can be changed significantly, and a better stirring effect can be achieved in a shorter time. While ensuring work efficiency, the quality of the prepared copolyol can also be guaranteed.

[0021] (2) The processing equipment and method for preparing copolyols use a second motor to drive the rotating shaft to rotate, and the connecting rod to drive the rotating sleeve to rotate. Then, the control rod causes the intermediate plate to rotate slightly along the positioning rod, so that the intermediate plate swings back and forth slightly. This allows the copolyol raw material to tilt at a certain angle in the mixing drum, and then return to its original position and tilt again. The purpose is to change the position of the raw material over a wide range, avoid the mixing shaft from continuously stirring the raw material at the same position, and improve the quality of raw material mixing.
