Description

Technical fields:

[0001] This utility model relates to the field of chemical equipment technology, specifically to a neopentyl glycol conveying and regulating device for improving the performance of oil-free alkyd resins. Background technology:

[0002] Neopentyl glycol is an important raw material in the production process of improving the performance of oil-free alkyd resin. In the process of transporting neopentyl glycol raw materials, the conveying pipelines used are all single pipes, and the flow rate can only be controlled by switching valves, but the flow rate cannot be measured. Moreover, all of them are manually adjusted, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a neopentyl glycol raw material conveying and control device to meet production needs. Utility Model Content:

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new pentylene glycol delivery and control device for improving the performance of oil-free alkyd resin. It is more versatile, can be mechanically or electrically adjusted, and can measure the flow rate while adjusting the flow rate.

[0004] To address the problems existing in the background technology, the present invention adopts the following technical solution: it includes a conveying pipeline and a regulating valve. The regulating valve has a valve port, which is connected to the top end of the conveying pipeline. A channel is opened at the upper part of the valve port. The regulating valve has a threaded hole inside, through which a threaded rod passes. The threaded rod is connected to the threaded hole by threads. Both ends of the threaded rod pass through the regulating valve. A handwheel is provided at one end of the threaded rod, and a flow regulating hole is opened on the threaded rod.

[0005] The flow regulating orifice includes a first regulating orifice, a second regulating orifice, and a third regulating orifice. The first regulating orifice, the second regulating orifice, and the third regulating orifice are distributed at equal intervals on the threaded rod. The first regulating orifice and the second regulating orifice are both columnar structures, and the third regulating orifice is a serpentine structure.

[0006] The diameter of the first adjusting hole is larger than that of the second adjusting hole, and the diameter of the second adjusting hole is the same as that of the third adjusting hole.

[0007] Buffer plates are installed at the convex corners of the third adjustment hole, and the buffer plates are distributed alternately from top to bottom.

[0008] The other end of the threaded rod is provided with a limiting block.

[0009] The other end of the threaded rod is connected to the drive motor via a coupling.

[0010] A sealing gasket is provided at the connection between the valve port and the delivery pipeline.

[0011] The channel is connected to the delivery pipeline via a valve port.

[0012] The advantages of this utility model are its simple structure and ease of use. By replacing the handwheel and drive motor, it achieves both mechanical and electric adjustment functions, which can be switched according to operational needs, saving time and effort. The three adjustment holes on the threaded rod realize the functions of flow regulation and buffering. The diameter of the adjustment hole can be specified and the volume of the adjustment hole can be calculated, thereby achieving the purpose of flow measurement and meeting operational needs.

[0017] Referring to the figures, this utility model specifically adopts the following embodiment: It includes a conveying pipe 1 and a regulating valve 3. The regulating valve 3 has a valve port 12, which is connected to the top end of the conveying pipe 1. A channel 4 is formed at the upper part of the valve port 12. The regulating valve 3 has a threaded hole, through which a threaded rod 5 passes. The threaded rod 5 is connected to the threaded hole by threads, and both ends of the threaded rod 5 pass through the regulating valve 3. A handwheel 2 is provided at one end of the threaded rod 5. A flow regulating hole is formed on the threaded rod 5. The flow regulating hole includes a first regulating hole 6, a second regulating hole 7, and a third regulating hole 9. The first regulating hole 6, the second regulating hole 7, and the third regulating hole 9 are distributed at equal intervals on the threaded rod 5. The first regulating hole 6 and the second regulating hole 7 are both columnar structures, and the third regulating hole 9 is serpentine. The diameter of the first regulating hole 6 is larger than the diameter of the second regulating hole 7, and the diameter of the second regulating hole 7 is the same as the diameter of the third regulating hole 9. Buffer plates 8 are installed at the inner convex corners of the third regulating hole 9, and the buffer plates 8 are distributed alternately from top to bottom. The other end of the threaded rod 5 is provided with a limiting block 10. The other end of the threaded rod 5 is connected to the drive motor 13 via a coupling. A sealing gasket 11 is provided at the connection between the valve port 12 and the conveying pipe. The channel 4 is connected to the conveying pipe 1 via the valve port 12.

[0018] When this neopentyl glycol raw material conveying and regulating equipment for improving the performance of oil-free alkyd resin is in operation, the valve port 12 of the regulating valve 3 is installed on the conveying pipe 1. To prevent the neopentyl glycol raw material in the conveying pipe 1 from flowing onto the ground and polluting the environment through gaps, a sealing gasket 11 is installed between the valve port 12 and the conveying pipe 1. The sealing gasket 11 is soft and can elastically expand and contract according to the shape of the conveying pipe 1, completely wrapping the conveying pipe 1 to prevent the neopentyl glycol raw material from overflowing. The neopentyl glycol raw material in the conveying pipe 1 flows out through the valve port 12 and the channel 4 in sequence. When the regulating valve 3 is in the closed state, the threaded rod 5 and the inner wall of the regulating valve 3 itself block the channel 4, and the neopentyl glycol raw material in the conveying pipe 1 cannot flow out. When the regulating valve 3 is in use, the handwheel 2 is turned. Since the threaded rod 5, which is fixedly connected to the handwheel 2, is threadedly connected to the threaded hole, the threaded rod 5 will rotate with the handwheel 3. When the first regulating hole 6 is rotated to coincide with the channel 4, the neopentyl glycol raw material in the conveying pipe 1 will flow out through the first regulating hole 6. Channel 4 is connected to other production equipment.

[0019] As the handwheel 2 continues to rotate, the threaded rod 5 continues to rotate, and the second adjusting hole 7 and the third adjusting hole 9 will successively coincide with the channel 4, and the neopentyl glycol raw material in the conveying pipe 1 can also flow out through the second adjusting hole 7 or the third adjusting hole 9.

[0020] The diameters of the first regulating orifice 6, the second regulating orifice 7, and the third regulating orifice 9 decrease sequentially. When the first regulating orifice 6 completely overlaps with channel 4, the flow rate is at its maximum; when the second regulating orifice 7 completely overlaps with channel 4, the flow rate is at an intermediate level; and when the third regulating orifice 9 completely overlaps with channel 4, the flow rate is at its minimum. By changing the orifice diameters, the flow rate is regulated. The volume of the flow can also be calculated using the different orifice diameters. Since both the first regulating orifice 6 and the second regulating orifice 7 are cylindrical, knowing the diameter of the circle allows calculation of the orifice volume. This volume, representing the volume of neopentyl glycol feedstock, allows for the calculation of the volume of neopentyl glycol feedstock per unit time, thus enabling flow rate measurement.

[0021] Depending on the production volume requirements, the diameter of the flow orifice can be adjusted. It does not have to be a uniform specification of adjustment orifice. Different orifice diameters can be opened to control the flow rate and the volume of neopentyl glycol raw material flowing out per unit time.

[0022] The main function of the third regulating hole 9 is to buffer the neopentyl glycol raw material. This is to prevent the impact force from being too great and uncontrollable when the neopentyl glycol raw material flows out of the conveying pipeline 1. The third regulating hole 9 is serpentine in shape, and the inner wall is equipped with buffer plates 8 that are installed alternately on the upper and lower sides. The serpentine structure prolongs the flow time of the neopentyl glycol raw material, and the buffer plates 8 will consume part of the impact force of the neopentyl glycol raw material, thus playing a buffering role.

[0023] When adjusting using handwheel 2, it is necessary to rotate handwheel 2 quickly to ensure that the adjustment hole can quickly and accurately coincide with channel 4.

[0024] When it is difficult to turn the handwheel 2, turn on the drive motor 13. The drive motor 13 drives the threaded rod 5 to rotate, which is faster than the rotation speed of the handwheel 2. This can make it easier and faster to align the adjustment hole with the channel 4.

[0025] When handwheel 2 is rotated, to prevent excessive rotation and disengagement of the threaded rod 5 into the regulating valve 3, a limit block 10 is installed at the end of the threaded rod 5 opposite to the handwheel 2. The limit block 10 abuts against the outside of the regulating valve 3, thus preventing the threaded rod 5 from retracting into the regulating valve 3. When the drive motor 13 is used for rotation, handwheel 2 acts as a limiter to prevent excessive rotation of the drive motor 13, which would retract the threaded rod 5 into the regulating valve 3. Handwheel 2 will then abut against the outside of the regulating valve 3.

[0026] The volumes of the first regulating hole 6, the second regulating hole 7, and the third regulating hole 9 can all be calculated based on their dimensions. Based on the volume, the flow rate per minute can be determined, thereby calculating the amount of neopentyl glycol to be added in the production of oil-free alkyd resin.

[0027] The drive motor 13 can be connected to an external power source or a battery box to ensure its power supply. The drive motor 13 is model 180WD-M, manufactured by Guangzhou Demark Motor Co., Ltd.

[0028] In summary, this neopentyl glycol raw material conveying and control equipment for improving the performance of oil-free alkyd resin has a simple structure and is easy to use. By interchangeably using a handwheel and a drive motor, it achieves both mechanical and electric adjustment functions, which can be switched according to operational needs, saving time and effort. The three adjustment holes on the threaded rod realize the functions of flow regulation and buffering. The diameter of the adjustment hole can be specified and the volume of the adjustment hole can be calculated, thereby achieving the purpose of flow measurement and meeting production requirements.
