Description

Technical Field

[0001] This utility model relates to the field of anti-clogging technology, specifically to an anti-clogging C4 raw material pretreatment device for MTBE production. Background Technology

[0002] In the production process of methyl tert-butyl ether (MTBE), the pretreatment of C4 feedstock is crucial. As an important high-octane gasoline additive, the production quality and efficiency of MTBE largely depend on the effectiveness of feedstock pretreatment. Currently, the C4 feedstock used has a high viscosity, which poses many challenges to the production process. When high-viscosity C4 feedstock is added to the reactor for pretreatment, it easily adheres to the wall of the feed pipe. Over time, this adhered feedstock gradually accumulates, eventually causing the feed pipe to become blocked. Once the feed pipe becomes blocked, it will not only seriously affect the conveying efficiency of C4 feedstock and cause production interruption, but may also trigger a series of subsequent problems.

[0003] However, existing feed pipes generally lack effective anti-clogging structures. Most traditional feed pipes are simply pipe structures that do not fully consider the special properties of high-viscosity C4 raw materials during design. These feed pipes cannot effectively control the flow state of the raw materials and lack means to prevent the raw materials from sticking and accumulating. The anti-clogging effect is unsatisfactory. Therefore, it is necessary to design an anti-clogging C4 raw material pretreatment device for MTBE production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging C4 raw material pretreatment device for MTBE production, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A pretreatment device for anti-clogging C4 raw materials in MTBE production includes a feed pipe, an inner cavity of which is provided with a set of guide tubes for guiding the flow of C4 raw materials; the feed pipe and the guide tubes are connected by a buffer; a vibration component is provided on the outside of the guide tubes for dispersing the C4 raw materials accumulated in the feed pipe and preventing the C4 raw materials from forming a blockage on the inner wall of the guide tubes.

[0007] The above technical solution changes the flow direction of the raw materials, allowing them to flow in a relatively concentrated and orderly path, thus preventing the raw materials from spreading disorderly in the feed pipe. The vibration component transmits vibration to the guide tube through the support, causing the guide tube to vibrate at high frequency, keeping the C4 raw materials in a disturbed state and making it difficult for them to accumulate and stick on the tube wall of the guide tube. The vibration generated by the vibration component can promptly disperse these accumulated raw materials, allowing them to be mixed back into the flowing raw materials and continue to flow with them, thus preventing blockages from forming on the inner wall of the guide tube.

[0008] A further improvement of this utility model is that the vibration assembly includes a bracket, an eccentric wheel, a flexible coupling, and a motor. Two sets of the brackets are installed on the outer wall of the guide tube. Each set of brackets is rotatably connected to a set of eccentric wheels. The shaft of the eccentric wheel is connected to the output end of the motor via the flexible coupling. The flexible coupling can buffer transmission impact and protect the motor.

[0009] When the above technical solution is adopted, the motor starts when the device is running, and its power is smoothly transmitted to the eccentric wheel shaft through the flexible coupling. Due to the eccentric structure, the eccentric wheel generates a changing centrifugal force when it rotates, which drives the support and guide cylinder connected to it to vibrate, thereby breaking up the C4 raw material accumulated on the inner wall of the guide cylinder and ensuring the flow of raw materials.

[0010] A further improvement of this utility model is that a shock-absorbing pad is provided between the motor and the guide tube, which can reduce the impact of vibration on the motor and protect the motor.

[0011] In the above technical solution, the motor drives the eccentric wheel to vibrate the guide tube, and the shock-absorbing pad between the motor and the guide tube undergoes elastic deformation to absorb and disperse the vibration energy, reduce the vibration transmitted to the motor, and protect the motor to operate stably.

[0012] A further improvement of this utility model is that the buffer is a rubber pad, and a set of the rubber pads is connected to the outer walls of both ends of the guide tube, and the rubber pads are connected to the inner wall of the feed pipe.

[0013] Using the above technical solution, when the vibration component is working, the guide tube vibrates. Due to its elasticity, the rubber pads on the outer walls at both ends absorb and disperse the vibration energy. After buffering, the vibration is transmitted to the feed pipe, which greatly reduces the impact on the feed pipe and maintains the stable operation of the device.

[0014] A further improvement of the present invention is that the guide tube includes a guide pipe and a flared mouth. Two sets of the flared mouths are mirror-installed at both ends of the guide pipe, and a set of rubber pads is connected to the outer wall of the two sets of flared mouths at the ends away from the guide pipe.

[0015] The above technical solution, with its enlarged funnel-shaped opening, increases the receiving area of ​​C4 raw materials, guides the raw materials smoothly into the guide pipe, improves the flow state of the raw materials, and prevents the accumulation of raw materials at the inlet.

[0016] A further improvement of this utility model is that the feed pipe is a rectangular tube, and the guide tube is adapted to it.

[0017] Using the above technical solution, the rectangular structure provides a larger contact area for installing the flow guide tube and related components compared to other shapes such as circles.

[0018] A further improvement of this utility model is that both ends of the feed pipe are integrally formed with a set of flanges.

[0019] The above technical solution uses standardized connections, eliminating the need for customized complex interfaces, simplifying the process and improving installation efficiency.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0021] 1. In this utility model, C4 raw material enters through a feed pipe. A set of guide tubes inside the feed pipe are responsible for guiding the raw material. The feed pipe and the guide tubes are connected by a buffer to buffer the impact force during feeding and ensure stable operation of the equipment. The vibration component outside the guide tube works. These vibrations are smoothly transmitted to the inner wall of the guide tube through the buffer connected to the guide tube. Because C4 raw material has high viscosity, it is easy to stick and accumulate on the inner wall of the guide tube. The vibration generated by the vibration component can promptly disperse these accumulated raw materials, allowing them to be remixed into the flowing raw material and flow continuously with the raw material, avoiding blockage on the inner wall of the guide tube.

[0022] 2. When the motor of this utility model starts, its power is smoothly transmitted to the eccentric wheel shaft through the flexible coupling. Due to its eccentric structure, the eccentric wheel generates a changing centrifugal force when rotating, which drives the bracket and guide cylinder connected to it to vibrate. This disperses the C4 raw material accumulated on the inner wall of the guide cylinder, ensuring the flow of raw materials. The motor drives the eccentric wheel to vibrate the guide cylinder. The shock-absorbing pad between the motor and the guide cylinder elastically deforms, absorbing and dispersing the vibration energy, reducing the vibration transmitted to the motor, and protecting the motor to operate stably.

[0023] 3. When the guide tube of this utility model vibrates, the rubber pads on the outer walls at both ends absorb and disperse the vibration energy due to their elasticity. After buffering, the vibration is transmitted to the feed pipe, which greatly reduces the impact on the feed pipe and maintains the stable operation of the device. The enlarged opening shape of the flared mouth can increase the receiving area of ​​C4 raw materials, guide the raw materials smoothly into the guide tube, improve the flow state of the raw materials, and prevent the raw materials from accumulating at the inlet. Compared with other shapes such as circles, the rectangular structure can provide a larger contact area for installing the guide tube and related components. The flange parts adopt standardized connections, eliminating the need for customized complex interfaces, simplifying the process and improving installation efficiency. Attached Figure Description

[0033] Example 1

[0034] like Figure 1-6 As shown, this utility model provides an anti-clogging C4 raw material pretreatment device for MTBE production, including a feed pipe 1, a set of guide tubes is provided in the inner cavity of the feed pipe 1, the guide tubes are used to guide the C4 raw material; the feed pipe 1 and the guide tubes are connected by a buffer; a vibration component is provided on the outside of the guide tubes, the vibration component is used to disperse the C4 raw material accumulated in the feed pipe 1, and prevent the C4 raw material from forming a blockage on the inner wall of the guide tube.

[0035] In this embodiment, C4 raw material enters through feed pipe 1. A set of guide tubes in the inner cavity of feed pipe 1 is responsible for guiding the raw material. Feed pipe 1 and guide tubes are connected by a buffer to buffer the impact force during feeding and ensure stable operation of the equipment. Vibration components outside the guide tubes work. These vibrations are smoothly transmitted to the inner wall of the guide tubes through the buffer connected to the guide tubes. Since C4 raw material has high viscosity, it is easy to stick and accumulate on the inner wall of the guide tubes. The vibration generated by the vibration components can promptly disperse these accumulated raw materials, allowing them to be remixed into the flowing raw material and continue to flow with the raw material, avoiding blockage on the inner wall of the guide tubes.

[0036] like Figure 1-6 As shown, in this embodiment, preferably, the vibration assembly includes a bracket 2, an eccentric wheel 3, a flexible coupling 4, and a motor 5. Two sets of brackets 2 are installed on the outer wall of the guide tube. Each set of brackets 2 is rotatably connected to a set of eccentric wheels 3. The shaft of the eccentric wheel 3 is connected to the output end of the motor 5 via the flexible coupling 4. The flexible coupling 4 can buffer the transmission impact and protect the motor 5. A shock-absorbing pad 6 is provided between the motor 5 and the guide tube. The shock-absorbing pad 6 can reduce the impact of vibration on the motor 5 and protect the motor 5.

[0037] When motor 5 starts, its power is smoothly transmitted to the shaft of eccentric wheel 3 via flexible coupling 4. Due to its eccentric structure, eccentric wheel 3 generates a changing centrifugal force when rotating, which drives the support 2 and the guide cylinder connected to it to vibrate. This disperses the C4 raw material accumulated on the inner wall of the guide cylinder, ensuring the flow of raw material. Motor 5 drives eccentric wheel 3 to vibrate the guide cylinder. The shock-absorbing pad 6 between motor 5 and guide cylinder elastically deforms, absorbing and dispersing the vibration energy, reducing the vibration transmitted to motor 5, and protecting the stable operation of the motor.

[0038] like Figure 1-6 As shown, in this embodiment, preferably, the buffer is a rubber pad 7. A set of rubber pads 7 is connected to the outer wall of each end of the guide tube. The rubber pads 7 are connected to the inner wall of the feed pipe 1. The guide tube includes a guide pipe 8 and a flared mouth 9. Two sets of flared mouths 9 are mirror-installed at both ends of the guide pipe 8. A set of rubber pads 7 is connected to the outer wall of the end of the two sets of flared mouths 9 away from the guide pipe 8. The feed pipe 1 is a rectangular tube. The guide tube is adapted to 1. A set of flanges 10 is integrally formed at both ends of the feed pipe 1.

[0039] The guide tube vibrates, and the rubber pads 7 on the outer walls at both ends absorb and disperse the vibration energy due to their elasticity. After buffering, the vibration is transmitted to the feed pipe 1, which greatly reduces the impact on the feed pipe 1 and maintains the stable operation of the device. The enlarged opening shape of the flared mouth 9 can increase the receiving area of ​​C4 raw materials, guide the raw materials smoothly into the guide tube 8, improve the flow state of the raw materials, and prevent the raw materials from accumulating at the inlet. Compared with other shapes such as circles, the rectangular structure can provide a larger contact area for installing the guide tube and related components. The flange 10 adopts a standardized connection, eliminating the need for customized complex interfaces, simplifying the process and improving installation efficiency.

[0040] Let me explain the working principle in detail below.

[0041] like Figure 1-6 As shown, C4 raw material enters through feed pipe 1. A set of guide tubes inside feed pipe 1 guides the raw material. Motor 5 starts, and its power is smoothly transmitted to the shaft of eccentric wheel 3 through flexible coupling 4. Due to its eccentric structure, eccentric wheel 3 generates a changing centrifugal force when rotating, which drives the support 2 and guide tubes connected to it to vibrate, thereby breaking up the C4 raw material accumulated on the inner wall of the guide tube and ensuring the flow of raw material. Motor 5 drives eccentric wheel 3 to vibrate the guide tube. The shock-absorbing pads 6 between motor 5 and guide tube deform elastically to absorb and disperse vibration energy, reduce the vibration transmitted to motor 5, and protect the stable operation of motor. When the guide tube vibrates, the rubber pads 7 on the outer walls at both ends absorb and disperse vibration energy due to their elasticity. After buffering, the vibration is transmitted to feed pipe 1, which greatly reduces the impact on feed pipe 1 and maintains the stable operation of the device. The enlarged opening shape of the flared mouth 9 can increase the receiving area of ​​C4 raw material, guide the raw material smoothly into the guide pipe 8, improve the flow state of raw material, and prevent raw material accumulation at the inlet.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
