[0002] Nylon 6 resin is a commonly used engineering plastic. During the extrusion production process, the temperature of the newly extruded nylon 6 resin is relatively high. Therefore, a vacuum pump cooling water pipe is required to cool the nylon 6 resin after production to ensure the smooth production of the nylon 6 resin in the later stage.

[0003] The internal structure of the cooling water pipes used in connection with existing vacuum pumps is relatively simple, and most of them do not have a heat preservation effect, resulting in a rapid dissipation of the internal coolant temperature, affecting the subsequent operation efficiency of the vacuum pump and slowing down the subsequent nylon 6 resin production efficiency. At the same time, the connection between the cooling water pipe and the vacuum pump is mostly carried out by tightening multiple sets of bolts. This installation method is relatively cumbersome and affects the efficiency of subsequent disassembly and maintenance. Utility Model Content

The front end of the outer side of the fixing rod is provided with a spring connected to the adjusting collar, which is convenient for the operator to realize the rapid disassembly and assembly function of the water pipe in the later stage.

[0008] According to the cooling water pipe structure of a vacuum pump suitable for producing nylon resin, three groups of limiting grooves are provided on the outside of the connecting flange, and limiting plates connected to the L-shaped fixing plate are inserted inside the three groups of limiting grooves, which facilitates the limiting installation of the L-shaped fixing plate.

[0013] According to the cooling water pipe structure of a vacuum pump suitable for producing nylon 6 resin, the exterior of the spring is sprayed with an anti-rust coating to prevent rust from affecting the subsequent use effect.

The adjacent sides of the three groups of L-shaped fixing plates 7 are all hinged with a hinge rod 4.

[0027] There are multiple groups of fixing grooves 12, and the multiple groups of fixing grooves 12 are evenly opened on the outside of the extension tube 5. The fixing rod 10 passes through the top of the front end of the adjusting collar 6, and the fixing rod 10 is engaged with the inside of the fixing groove 12 and cooperates with it. The front end of the outer side of the fixing rod 10 is provided with a spring 11 connected to the adjusting collar 6.

[0028] Three groups of limiting grooves are formed on the outside of the connecting flange 2 , and limiting plates connected to the L-shaped fixing plate 7 are inserted into the inside of the three groups of limiting grooves.

[0029] Three sets of hinged seats are provided on the outer side of the adjusting collar 6 , and the three sets of hinged seats cooperate with the hinged rod 4 .

[0034] Working principle: When in use, the operator directly takes the water pipe 1 and the above components to drive a set of extension tubes 5 to be installed on the input or output end of the external vacuum pump, and then the structural design of the sealing ring 3 can effectively improve the sealing performance of the connection between the extension tube 5 and the input or output end of the vacuum pump, and the other end of the water pipe 1 is plugged into the designated position of the external instrument.
