Description

Technical Field

[0001] This utility model relates to the field of circulating water pipe connection technology, and in particular to a reaction vessel jacketed constant temperature circulating water pipe connection device. Background Technology

[0002] In the field of chemical technology, such as the production of coating emulsions, the use of a jacketed constant temperature circulating water pipeline system for reactors is a common device for temperature control of reactors. It is also widely used in processes requiring precise temperature control in industries such as pharmaceuticals and food.

[0003] The jacketed constant temperature circulating water pipeline of the reactor mainly consists of a jacket structure, a constant temperature circulation device, and a piping system. The jacket structure is a sealed cavity welded or wrapped around the outer wall of the reactor, through which circulating water flows. The constant temperature circulation device includes a heater, cooler, circulating pump, temperature sensor, and control system. The piping system is used to connect the jacket and the constant temperature equipment, and is usually made of stainless steel or corrosion-resistant materials. However, after long-term use, scale is prone to form on the inner walls of the piping system and jacket structure. The long-term accumulation of scale can hinder the flow of internal water, and in severe cases, blockage may occur. Therefore, it is necessary to disassemble the pipes and jacket device and then clean the scale on the inner walls of the pipes and jacket device.

[0004] The existing two connected pipes or the pipe and the jacket device are all connected by flanges. Since the flange is circular, the height of the through hole on the outside of the flange is different from the ground. When the maintenance personnel fix the bellows, they need to change their posture according to the position of the through hole (sometimes they need to bend over, lie on their back, or squat down) and continuously assemble the bolts and nuts in different positions. This increases the difficulty of fixing two adjacent pipes and the time and labor costs required. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a jacketed constant temperature circulating water pipeline connection device for a reaction vessel. The aim is to improve the existing technology where, due to the same diameter between the pouring port on the mold and the pipeline, when the molten metal enters the pouring port, its flow rate is relatively fast because it does not contact the side wall of the pouring port (only contacting the air). After entering the pouring port, it will contact the side wall of the pouring port, and the excessive flow rate will impact the side wall of the pipeline. Under these two conditions, the molten metal is prone to generating eddies in the pouring pipeline, resulting in a large number of bubbles inside the molten metal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The jacketed constant temperature circulating water pipeline connection device for the reactor includes:

[0008] Two circulating water pipes, each with a rotatable connecting ring installed at both ends;

[0009] The connector is located outside the connecting ring. It allows two adjacent connecting rings to be connected, and the connecting ring can rotate along its own axis to adjust its installation position.

[0010] As a further description of the above technical solution:

[0011] Two sealed bearings are fixedly sleeved on the outer walls of both circulating water pipes, and the inner walls of the four connecting rings are fixedly sleeved on the outer walls of the four sealed bearings respectively.

[0012] As a further description of the above technical solution:

[0013] The connector includes a fixing rod and a limiting nut. On the outer wall of one of the connecting rings located on the outer wall of the same circulating water pipe, multiple fixing rods are rotatably installed in a ring shape. The outer walls of the four connecting rings are all provided with grooves that match the fixing rods in a ring shape. The outer walls of the multiple fixing rods are provided with threaded grooves along their own axis, and the outer walls of the multiple fixing rods are all provided with limiting nuts through threaded engagement.

[0014] As a further description of the above technical solution:

[0015] Support blocks are fixedly installed on the outer walls of multiple fixed rods. The inner wall of the groove on the outer wall of another connecting ring located on the outer wall of the same circulating water pipe is provided with a receiving groove that matches the support block.

[0016] As a further description of the above technical solution:

[0017] One end of each of the multiple support blocks is rotatably fitted with ball bearings that contact the inner wall of the receiving groove.

[0018] As a further description of the above technical solution:

[0019] Each of the four connecting rings has a sealing ring fixedly installed at one end, and each of the four connecting rings has a sealing groove that matches the sealing ring at one end.

[0020] This utility model has the following beneficial effects:

[0021] This utility model enables the connection of two adjacent connecting rings through a connector. At the same time, the connecting ring can rotate along its own axis, thereby adjusting the installation position of the connecting ring. The installation position of the connecting ring can be adjusted arbitrarily, so that multiple limit nuts can be easily installed on the outside of multiple fixing rods, reducing the difficulty of connecting two adjacent circulating water pipes and the required time and labor costs.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-6 One embodiment provided by this utility model:

[0032] The reaction vessel jacketed constant temperature circulating water pipeline connection device includes: two circulating water pipes 1 and connectors.

[0033] Two connecting rings 2 are rotatably installed at both ends of the two circulating water pipes 1. Two sealing bearings 8 are fixedly sleeved on the outer walls of the two circulating water pipes 1. The inner walls of the four connecting rings 2 are fixedly sleeved with the outer walls of the four sealing bearings 8 respectively. The ends of the four sealing bearings 8 near the opening of the circulating water pipe 1 are flush with the opening of the circulating water pipe 1. At the same time, the two ends of the four connecting rings 2 are flush with the two ends of the sealing bearings 8. When one end of the two circulating water pipes 1 comes into contact, the ends of the connecting rings 2 at the two ends of the circulating water pipes 1 fit together. When the two circulating water pipes 1 are connected, the sealing bearings 8 can prevent liquid from leaking from the connection of the circulating water pipes 1.

[0034] The connector includes a fixing rod 3 and a limiting nut 4. Multiple fixing rods 3 are rotatably mounted on the outer wall of one of the connecting rings 2 on the same circulating water pipe 1, arranged in a ring shape. The outer walls of all four connecting rings 2 have grooves 9 that fit the fixing rods 3. The outer walls of the fixing rods 3 are threaded along their own axes, and the limiting nuts 4 are threaded onto the outer walls of all the fixing rods 3. When one end of each of the two circulating water pipes 1 is brought into contact with each other, the grooves 9 on the outer walls of the two connecting rings 2 are aligned. Then, the fixing rod 3 is moved, causing it to rotate inwards around the rotating shaft until it enters the grooves 9. The inner wall of the groove 9 is opened in the wall, and the outer wall of the fixing rod 3 is kept parallel to the inner wall of the groove 9 away from its opening. Then, the limiting nut 4 is sleeved on the outer side of the fixing rod 3 away from the rotating shaft. Then, the limiting nut 4 is continuously rotated, so that the limiting nut 4 moves closer to the rotating shaft until one end of the limiting nut 4 is tightly fitted with the outer wall of the connecting ring 2. Thus, the fixing rod 3 is pulled by the cooperation of the limiting nut 4 and the threaded groove, thereby realizing the connection of the two circulating water pipes 1. Through the mutual cooperation of the limiting nut 4 and the fixing rod 3, the two circulating water pipes 1 can be squeezed closer to each other, so that the contact ends of the two circulating water pipes 1 are tightly fitted to prevent leakage.

[0035] When connecting two circulating water pipes 1, the connecting ring 2 can be continuously rotated to adjust its position, so that the fixing rods 3 at different positions can be rotated to any position at will, which is beneficial for construction personnel to install multiple limit nuts 4 on the outside of multiple fixing rods 3.

[0036] Support blocks 5 are fixedly installed on the outer walls of multiple fixed rods 3. The inner wall of the groove 9 on the outer wall of another connecting ring 2 located on the outer wall of the same circulating water pipe 1 is provided with a receiving groove 11 that matches the support block 5. One end of the multiple support blocks 5 is rotatably installed with a ball 6 that contacts the inner wall of the receiving groove 11. After the fixed rod 3 enters the groove 9 on the outer wall of the two connecting rings 2, the end of the support block 5 away from the fixed rod 3 enters the inner cavity of the receiving groove 11. When the outer wall of the fixed rod 3 is parallel to the inner wall of the groove 9 away from its own opening, the outer wall of the ball 6 and the inner wall of the receiving groove 11 away from its own opening fit together, thereby supporting the outer wall of the fixed rod 3, so that the limiting nut 4 can fit tightly with the outer wall of the connecting ring 2.

[0037] When one end of the limiting nut 4 is attached to one end of the connecting ring 2 and moves continuously, the fixing rod 3 is pulled down and continues to move closer to the limiting nut 4. At this time, the ball 6 rotates along the tangential direction that contacts the inner wall of the receiving groove 11. While limiting the fixing rod 3, it can also reduce the friction when the fixing rod 3 moves along its own axis, and improve the smoothness of the fixing rod 3 moving along its own axis.

[0038] Each of the four connecting rings 2 has a sealing ring 10 fixedly installed at one end, and each of the four connecting rings 2 has a sealing groove 7 that matches the sealing ring 10. When one end of two connecting rings 2 is tightly fitted, the sealing ring 10 enters the inner cavity of the sealing groove 7, thereby further improving the sealing performance between the two connecting rings 2.

[0039] The fixing rod 3, the limiting nut 4, and the support block 5 constitute the connector. The connector can connect two adjacent connecting rings 2. At the same time, the connecting ring 2 can rotate along its own axis, thereby adjusting the installation position of the connecting ring 2. The installation position of the connecting ring 2 can be adjusted arbitrarily, so that multiple limiting nuts 4 can be easily installed on the outside of multiple fixing rods 3, reducing the difficulty and time and effort required to connect two adjacent circulating water pipes 1.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
