Polyvinyl chloride reaction stirring device

Abstract

This utility model relates to the technical field of stirring devices, and specifically discloses a polyvinyl chloride reaction stirring device, including a discharge pipe and a sampling mechanism including a connecting hole, a connecting pipe, a filter pipe, a filter plate, and a cover plate. Each fixing mechanism includes an insert plate, a groove, a threaded hole, and a screw. Rotating the screw moves it away from the insert plate, at which point the cover plate is pulled to disengage it from the filter pipe. The material flowing in the discharge pipe flows into the pipe formed by the connecting pipe and the filter pipe, and flows out from the opening of the filter pipe. During the material flow, the material comes into contact with the filter plate. If material accumulates on the filter plate, it directly reflects that the material is unqualified, making it easy to detect production problems in a timely manner. At the same time, the staff can test the material flowing out of the opening of the filter pipe. Therefore, it is not necessary to open the tank cover or disassemble the equipment during the sampling process, avoiding the introduction of impurities and ensuring the purity of the material. The sampling process is simple and improves work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, and in particular to a polyvinyl chloride reaction stirring device. Background Technology

[0002] Polyvinyl chloride (PVC) reaction stirring devices are used in the PVC production process to stir, mix, and disperse materials such as vinyl chloride monomer, promoting the smooth progress of the polymerization reaction. One type of high-speed mixing and stirring device has the following structure:

[0003] 1. Mixing tank: A container for storing materials;

[0004] 2. Agitator: Various types, such as paddle type, anchor type, frame type, spiral type, turbine type, propeller type, etc., are installed in the tank through a stirring shaft and perform stirring, mixing, and dispersing operations on materials during operation;

[0005] 3. Discharge pipe: Used to discharge the polyvinyl chloride material that has been mixed and reached the reaction requirements, and transport it to the subsequent processing steps.

[0006] After the polyvinyl chloride reaction is stirred, the material flows out through the discharge pipe. When sampling is required, there are generally two methods: one is to open the tank lid of the mixing tank for sampling, and the other is to sample through the discharge pipe. Both of these methods may encounter the following problems:

[0007] 1. When the can lid is opened, due to the large opening, impurities from the external environment can easily enter the can, especially in an open workshop environment, where the mixing of impurities leads to a decrease in the purity of the material.

[0008] 2. If the discharge pipe is rigidly connected to the subsequent processing equipment, it is necessary to disassemble the flange, pipe valves and other components when taking samples, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a polyvinyl chloride reaction stirring device, which solves the following problems: First, when the tank lid is opened, impurities from the external environment can easily enter the tank due to the large opening, especially in open workshop environments, where impurities can cause a decrease in material purity. Second, if the discharge pipe is rigidly connected to subsequent processing equipment, flanges, pipe valves, and other components need to be disassembled during sampling, which is time-consuming, labor-intensive, and inefficient.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A polyvinyl chloride (PVC) reaction stirring device includes a discharge pipe. A sampling mechanism for taking samples is provided on the outside of the discharge pipe. The sampling mechanism includes a connecting hole, a connecting pipe, a filter pipe, a filter plate, and a cover plate. The connecting hole is located on the outside of the discharge pipe and communicates with the inside of the discharge pipe. One end of the connecting pipe is fixedly installed inside the connecting hole. The filter pipe is located at the other end of the connecting pipe. The filter plate is located inside the filter pipe. The end of the cover plate is snapped into the inside of the filter pipe. Both ends of the filter pipe are provided with fixing mechanisms for fixing the cover plate. Each fixing mechanism includes an insert plate, a groove, a threaded hole, and a screw. The insert plate is fixedly installed on the outside of the filter pipe. The groove is located on the outside of the cover plate. The insert plate is slidably connected to the inside of the groove. The threaded hole is located on the side of the cover plate corresponding to the groove and communicates with the inside of the groove. The screw is threadedly connected to the inside of the threaded hole.

[0012] Preferably, the connecting pipe has an external thread, the filter pipe has a threaded sleeve fixedly installed on the outside, the threaded sleeve is threaded to the outside of the external thread, and two handles are fixedly installed on the outside of the threaded sleeve.

[0013] Preferably, a limiting ring is fixedly installed inside the filter tube to restrict the downward movement of the filter plate, and the filter plate is attached to the surface of the limiting ring.

[0014] Preferably, the external thread has an annular washer attached to the external movable sleeve.

[0015] Preferably, each screw is fixedly connected to the outside of a rope, and the other end of the rope is fixedly connected to the outside of the cover plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Rotate the screw to move it away from the insert plate. At this time, pull the cover plate to disconnect the cover plate from the filter tube. The material flowing in the discharge pipe flows into the pipe formed by the connecting pipe and the filter tube, and flows out from the opening of the filter tube. During the material flow, the material will come into contact with the filter plate. If there is material accumulation on the filter plate, it can directly reflect that the material is unqualified, which can facilitate the timely detection of production problems. At the same time, the staff can test the material flowing out of the opening of the filter tube. Therefore, it is not necessary to open the tank cover or disassemble the equipment during the sampling process, avoiding the introduction of impurities and ensuring the purity of the material. At the same time, the sampling process is simple and improves work efficiency.

[0018] 2. When it is necessary to replace the filter plate, rotate the threaded sleeve to disconnect the threaded sleeve from the external thread. At this time, the connection between the filter tube and the connecting tube is disconnected, and the filter plate can be poured out. The filter plate is detachable, which facilitates the replacement of filter plates of different specifications, thereby improving the applicability of the sampling mechanism.

[0026] This application provides a polyvinyl chloride reaction stirring device, which effectively solves the technical problems of: firstly, when the tank lid is opened, impurities from the external environment can easily enter the tank due to the large opening, especially in open workshop environments, where impurities can cause a decrease in material purity; secondly, if the discharge pipe is rigidly connected to the subsequent processing equipment, flanges, pipe valves and other components need to be disassembled during sampling, which is time-consuming, labor-intensive and inefficient.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the following problems: First, when the can lid is opened, impurities from the external environment can easily enter the can, especially in open workshop environments, where impurities can cause a decrease in material purity. Second, if the discharge pipe is rigidly connected to subsequent processing equipment, sampling requires disassembling flanges, pipes, valves, and other components, which is time-consuming, labor-intensive, and inefficient. The overall approach is as follows:

[0029] To address the problems existing in the prior art, this utility model provides a polyvinyl chloride reaction stirring device, including a discharge pipe 1. A sampling mechanism for sampling is provided on the outside of the discharge pipe 1. The sampling mechanism includes a connecting hole 2, a connecting pipe 3, a filter pipe 4, a filter plate 5, and a cover plate 6. The connecting hole 2 is opened on the outside of the discharge pipe 1 and communicates with the inside of the discharge pipe 1. One end of the connecting pipe 3 is fixedly installed inside the connecting hole 2. The filter pipe 4 is located at the other end of the connecting pipe 3. The filter pipe 4 is made of transparent material to facilitate observation of the material accumulation on the filter plate 5 and to determine whether the material contains impurities or is unqualified. The filter plate 5 is located inside the filter pipe 4, and the end of the cover plate 6 is snapped into the inside of the filter pipe 4.

[0030] The connecting hole 2 is the channel through which the material enters the sampling mechanism from the discharge pipe 1. The connecting pipe 3 allows the material to be transported from the discharge pipe 1 to the filter pipe 4. The filter pipe 4 serves as the flow channel for the material during sampling. The filter plate 5 is installed inside to filter the material. The cover plate 6 is used to seal the opening of the filter pipe 4.

[0031] Both ends of the filter tube 4 are provided with fixing mechanisms for fixing the cover plate 6. Each fixing mechanism includes an insert plate 7, a groove 8, a threaded hole 9, and a screw 10. The insert plate 7 is fixedly installed on the outside of the filter tube 4. The groove 8 is opened on the outside of the cover plate 6. The insert plate 7 is slidably connected to the inside of the groove 8. The threaded hole 9 is opened on the side of the cover plate 6 corresponding to the groove 8. The threaded hole 9 communicates with the inside of the groove 8. The screw 10 is threadedly connected to the inside of the threaded hole 9. The insert plate 7 is slidably connected to the groove 8 of the cover plate 6 to provide guidance and initial positioning for the cover plate 6. Rotating the screw 10 can make the screw 10 abut or separate from the insert plate 7, thereby realizing the fixing or disassembly of the cover plate 6.

[0032] The connecting pipe 3 has an external thread 11, and the filter pipe 4 has a threaded sleeve 12 fixedly installed on its exterior. The threaded sleeve 12 is threaded to the outside of the external thread 11. Through the threaded connection, the filter pipe 4 and the connecting pipe 3 are detachably connected, which facilitates the installation, disassembly and maintenance of the filter pipe 4, and makes it easier to replace the filter plate 5.

[0033] The threaded sleeve 12 has two handles 13 fixedly mounted on its exterior, which facilitates the rotation of the threaded sleeve 12.

[0034] A limiting ring 14 is fixedly installed inside the filter tube 4 to restrict the downward movement of the filter plate 5. The filter plate 5 is attached to the surface of the limiting ring 14, and the limiting ring 14 is located below the filter plate 5 to prevent the filter plate 5 from moving downward under the pressure of the material, thus ensuring the stability of the filtration effect.

[0035] An annular washer 15 is fitted onto the external movable sleeve of the external thread 11 to increase the stability of the connection between the threaded sleeve 12 and the external thread 11.

[0036] Each screw 10 is fixedly connected to the outside of a rope 16, with the other end of the rope 16 fixedly connected to the outside of the cover plate 6. This prevents the screw 10 from falling off or being lost, facilitates subsequent installation operations, and improves work efficiency.

[0037] Working principle:

[0038] The first step is to rotate the screw 10 away from the insert plate 7 when sampling. At this time, pull the cover plate 6 to disconnect the cover plate 6 from the filter tube 4. The material flowing in the discharge pipe 1 flows into the pipe formed by the connecting pipe 3 and the filter tube 4 and flows out from the opening of the filter tube 4. During the material flow, the material will come into contact with the filter plate 5. The filter holes on the filter plate 5 will filter the material, intercepting unsuitable particles above the filter plate 5, while qualified particles will flow out through the filter holes. At the same time, if there is material accumulation on the filter plate 5, it can directly reflect that the material is unqualified, which can facilitate the timely detection of production problems. At the same time, the staff will test the material flowing out of the opening of the filter tube 4.

[0039] The second step is to rotate the threaded sleeve 12 to disconnect the threaded sleeve 12 from the external thread 11. At this time, the connection between the filter tube 4 and the connecting tube 3 is disconnected, and the filter plate 5 can be poured out.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
