Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of PVC polymerization kettle reducer disassembly equipment, in particular to a PVC polymerization kettle reducer shaft ring disassembly device. Background Art
[0002] In the production process of PVC raw materials, the polymerization reactor is the main production equipment. During the vinyl chloride polymerization reaction, the polymerization reactor stirring high and low speed switching needs to be completed according to the reaction time. Therefore, the speed of the high-speed shaft of the polymerization reactor stirring reducer needs to be changed frequently, resulting in frequent wear of the high-speed shaft ring and oil leakage of the reducer.
[0003] Because the PVC polymerization kettle site is a major hazard source and the risk of hot fire heating is high, each time the reducer shaft ring is replaced, the reducer must be disassembled to the hot fire area for hot fire heating disassembly. After the new shaft ring is installed, the reducer can be hoisted. However, the polymerization kettle reducer is large and the reducer shaft ring is small, making disassembly difficult. In addition, the reducer disassembly and installation area is narrow. Therefore, the entire process is labor-intensive and the hoisting process is risky, affecting production.
[0004] Therefore, it is necessary to design a PVC polymerization kettle reducer disassembly device to reduce the lifting risk generated when disassembling the reducer and improve the maintenance efficiency and the safety of the working environment. Utility Model Content
[0005] In view of the problems of the prior art, the purpose of the present invention is to provide a PVC polymerization kettle reducer disassembly device to solve the problem that the PVC polymerization kettle reducer is large and the reducer shaft ring is small, making it difficult to disassemble.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A PVC polymerization kettle reducer disassembly device includes a sleeve, a drawing seat is provided at the top of the sleeve, a threaded push rod is provided on the drawing seat, a plurality of locking nuts are evenly provided at the lower part of the sleeve, a positioning clamp is provided at one end of the plurality of locking nuts, and a plurality of observation holes are evenly provided at the same height as the positioning clamp at the lower part of the sleeve.
[0008] More preferably, the positioning snap ring is an arc-shaped structure, and the positioning snap ring matches the shape of the reducer shaft ring.
[0009] More preferably, a positioning boss is provided below the drawing seat.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] This utility model addresses wear and oil leakage issues with the reducer collar of a PVC polymerization kettle reducer. This device allows for on-site removal and replacement of the reducer collar, reducing the risk of lifting during reducer removal and improving maintenance efficiency. Because the PVC polymerization kettle site is a major hazard source, removing the collar using this device also avoids the fire and explosion hazards associated with on-site hot work heating to remove the reducer collar, thereby improving the safety of the working environment.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0016] In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, in the description of the present invention, "several" means two or more, unless otherwise expressly and specifically defined.
[0017] like Figure 1 、 2As shown, a PVC polymerization kettle reducer disassembly device includes a sleeve 4, which can cover the reducer shaft ring and serve as a support seat for the locking nut 5. A drawing seat 2 is provided on the top of the sleeve 4, and a threaded push rod 1 is provided on the drawing seat 2. The threaded push rod 1 uses the end face of the reducer high-speed shaft to provide support and provide power for the disassembly process of the reducer shaft ring. The drawing seat 2 can prevent the threaded push rod 1 from slipping. A positioning boss 3 is provided under the drawing seat 2 to help position the threaded push rod 1 so that the threaded push rod 1 can be accurately pushed to the center of the end face of the reducer high-speed shaft to prevent the threaded push rod 1 from being deflected. Several locking nuts 5 are evenly opened at the lower part of the sleeve 4, and the locking nuts 5 evenly distribute the tightening force on the reducer shaft ring. A positioning snap ring 6 is welded at one end of the several locking nuts 5. The positioning snap ring 6 is an arc-shaped structure. The positioning snap ring 6 matches the shape of the reducer shaft ring, which is convenient for clamping the reducer shaft ring. Several observation holes 7 are evenly provided at the same height as the positioning snap ring 6 at the lower part of the sleeve 4. The fixed position of the reducer shaft ring is determined through the observation holes 7.
[0018] When the utility model is used in practice, when the reducer leaks oil, the motor is powered off, the reducer pulley and bearing cover are manually disassembled, the device is put on the reducer shaft ring, and the sleeve 4 is installed on the reducer shaft ring using the observation hole 7 so that the inner side surface of the positioning clamping ring 6 and the outer cylindrical surface of the reducer shaft ring are in the same vertical direction. The locking nut 5 is tightened in sequence using a wrench until the positioning clamping ring 6 is close to the reducer shaft ring, and the threaded push rod 1 is tightened to the end face of the reducer high-speed shaft using a wrench, and then the power rod is used to tighten the push rod 1, and the reducer shaft ring is slowly removed from the reducer high-speed shaft, and then the reducer high-speed shaft is wiped clean and a new shaft ring is installed. After using this device, the reducer shaft ring saves time and effort during the disassembly process, reduces the operation risk, improves the operating environment, and improves production efficiency.
[0019] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
