Description

Technical Field

[0001] This utility model relates to the field of chlorine blower technology, specifically a device for linking a chlorine blower. Background Technology

[0002] A chlorine blower is a specialized device for conveying and processing chlorine gas. It is widely used in industries such as chemical, water treatment, and pharmaceutical. When the blower's rotor rotates at high speed under the drive of a motor (such as an electric motor or steam turbine), the rotation of the impeller generates centrifugal force on the gas. The gas is drawn in from the impeller inlet, gains kinetic energy in the impeller, and then converts the kinetic energy into pressure energy in the diffuser. Finally, it is discharged through the outlet pipe. Since the compression of the gas consumes mechanical energy and converts it into heat energy, a cooling device is required during the compression process to prevent the gas temperature from becoming too high. In the chlor-alkali industry, chlorine blowers are used to transport chlorine gas generated in electrolytic cells to subsequent processing equipment.

[0003] Currently, the pressure linkage of chlorine blowers relies on a closed-loop system consisting of pressure sensors, electric actuators, and controllers. This system has high wiring and maintenance costs, and the signal transmission → calculation → execution process causes a 2-3 second delay in action. Furthermore, it poses a safety hazard in the event of a chlorine leak.

[0004] Therefore, a device that links with a chlorine blower is proposed to solve the above problems. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a device for linking chlorine blowers. This device aims to solve the problems of existing chlorine blower pressure linkage relying on a closed-loop system composed of a pressure sensor, electric actuator, and controller, resulting in high wiring and maintenance costs, a 2-3 second delay in action due to the signal transmission → calculation → execution process, and safety hazards in the event of chlorine leakage.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A device for linking a chlorine blower includes a chlorine blower, an outlet pipe connected to the outlet of the chlorine blower, a butterfly valve installed at one end of the outlet pipe, a connecting pipe connected to one end of the butterfly valve, and a linkage mechanism installed inside the connecting pipe, the linkage mechanism being able to control the opening and closing angle of the butterfly valve under different gas pressures inside the connecting pipe.

[0010] As a preferred embodiment of this utility model, the butterfly valve has a rotatable valve installed inside, and a first rotating connecting seat is installed on one side of the valve near the inside of the connecting pipe.

[0011] As a preferred embodiment of this utility model, the linkage mechanism is equipped with two support seats. The bottom of the support seats is fixedly installed on the inner bottom of the connecting pipe. Both support seats have round holes, and a slide rod is installed between the round holes on the two support seats. A pressing plate is installed on the end of the slide rod near the butterfly valve.

[0012] As a preferred embodiment of this utility model, a baffle is installed at the end of the slide rod away from the extrusion plate, a spring is installed on the inner side of the baffle, the spring is sleeved on the outer ring surface of the slide rod, and the other end of the spring is fixedly connected to the outer side of a support base.

[0013] As a preferred embodiment of this utility model, a second rotating connecting seat is installed on the outer side of the slide rod between the two support seats, a rotating plate is installed on the inner side of the second rotating connecting seat, and a return spring is installed on the connecting shaft between the rotating plate and the second rotating connecting seat.

[0014] As a preferred embodiment of this utility model, one end of the rotating plate is rotatably connected to a pull rod, and a through hole is provided between the top and bottom of one end of the pull rod. One end of the pull rod is rotatably connected to the first rotating connecting seat on the valve, and the through hole is sleeved on the rotating shaft. Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention delivers gas into a butterfly valve through an outlet pipe. The gas then enters a connecting pipe through the butterfly valve. When the pressure inside the connecting pipe exceeds a set pressure, a linkage mechanism controls the butterfly valve to reduce its opening angle to lower the gas pressure inside the connecting pipe. Once the gas pressure inside the connecting pipe returns to normal, the linkage mechanism controls the butterfly valve to fully open again, thus ensuring that chlorine gas is delivered within the connecting pipe while maintaining a suitable gas pressure. The linkage mechanism has a fast response time, effectively avoiding the action delay problem inherent in closed-loop systems that rely on pressure sensors, electric actuators, and controllers. This effectively prevents chlorine gas leakage caused by excessive gas pressure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1-4 This embodiment provides a device for linking a chlorine blower, including a chlorine blower 1. The outlet of the chlorine blower 1 is connected to an outlet pipe 11. A butterfly valve 2 is installed at one end of the outlet pipe 11, and a connecting pipe 3 is connected to the other end of the butterfly valve 2. A linkage mechanism 4 is installed inside the connecting pipe 3. The linkage mechanism 4 can control the opening and closing angle of the butterfly valve 2 under different gas pressures in the connecting pipe 3. When the device for linking the chlorine blower is in use, gas is delivered to the butterfly valve 2 through the outlet pipe 11. The gas enters the connecting pipe 3 through the butterfly valve 2. When the pressure in the connecting pipe 3 is greater than the set pressure, the linkage mechanism 4 controls the butterfly valve 2 to reduce the opening and closing angle to reduce the gas pressure in the connecting pipe 3. When the gas pressure in the connecting pipe 3 is normal, the linkage mechanism 3 controls the butterfly valve 2 to fully open again, thereby ensuring that chlorine is delivered in the connecting pipe 3 while maintaining a suitable gas pressure. The linkage mechanism 4 has a fast response time, effectively avoiding the problem of action delay in a closed-loop system composed of a pressure sensor, electric actuator, and controller, thereby effectively preventing chlorine leakage due to excessive gas pressure.

[0024] In this embodiment, as Figure 2 and Figure 3 As shown, two support seats 41 are installed on the linkage mechanism 4. The bottom of the support seat 41 is fixedly installed on the inner bottom of the connecting pipe 3. Both support seats 41 have round holes, and a slide rod 42 is installed between the round holes on the two support seats 41. A pressure plate 43 is installed on the end of the slide rod 42 near the butterfly valve 2. When the internal pressure of the connecting pipe 3 is too high, the gas pressure will squeeze the pressure plate 43. At this time, the slide rod 42 will slide in the direction of pressure delivery inside the round holes on the two support seats 41.

[0025] In this embodiment, as Figure 2 and Figure 3 As shown, a baffle 44 is installed at the end of the slide rod 42 away from the extrusion plate 43. A spring 45 is installed on the inner side of the baffle 44. The spring 45 is sleeved on the outer ring surface of the slide rod 42. The other end of the spring 45 is fixedly connected to the outer side of a support seat 41. Therefore, when the extrusion plate 43 is under normal pressure, the restoring property of the spring 45 can make the slide rod 42 slide back to its original position.

[0026] In this embodiment, as Figure 2 and Figure 3 As shown, a second rotating connecting seat 46 is installed on the outer surface of the slide rod 42 between the two support seats 41. A rotating plate 47 is installed on the inner side of the second rotating connecting seat 46. A return spring is installed on the connecting shaft between the rotating plate 47 and the second rotating connecting seat 46. Therefore, when the slide rod 42 slides, the rotating plate 47 will be squeezed by the support seat 41 and will also rotate clockwise. When the slide rod 42 slides back, under the action of the return spring, the rotating plate 47 will also rotate counterclockwise back to its original position.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a pull rod 48 is rotatably connected to one end of the rotating plate 47. A through hole is provided between the top and bottom of one end of the pull rod 48. One end of the pull rod 48 is rotatably connected to the first rotating connecting seat 22 on the valve 21, and the through hole is sleeved on the rotating shaft. When the pressure inside the connecting pipe 3 is too high, the slide rod 42 slides, causing the rotating plate 47 to rotate clockwise. The pull rod 48 moves towards the butterfly valve 2, reducing the opening angle of the valve 21 to reduce the gas pressure. When the pressure returns to normal, the slide rod 42 drives the rotating plate 47 to reset, and the pull rod 48 moves towards the rotating plate 47, gradually increasing the angle of the valve 21, thus realizing the mechanical linkage between the air pressure and the opening angle of the valve 21.

[0028] Working principle: When the device is in use, gas is supplied to the butterfly valve 2 through the outlet pipe 11. The gas enters the connecting pipe 3 through the butterfly valve 2. When the pressure in the connecting pipe 3 is greater than the set pressure, the gas pressure will squeeze the extrusion plate 43. At this time, the slide rod 42 will slide in the direction of pressure supply inside the round holes on the two support seats 41. When the slide rod 42 slides, the rotating plate 47 will be squeezed by the support seats 41 and will also rotate clockwise. At this time, the pull rod 48 moves towards the butterfly valve 2, opening the valve 21. The gas pressure is reduced by decreasing the opening angle. When the pressure returns to normal, the restoring property of the spring 45 allows the slide rod 42 to slide back to its original position. The slide rod 42 drives the rotating plate 47 to reset, and the pull rod 48 moves towards the rotating plate 47, gradually increasing the opening angle of the valve 21. This achieves mechanical linkage between the gas pressure and the opening angle of the valve 21. The linkage response time is fast, effectively avoiding the problem of action delay in a closed-loop system composed of a pressure sensor, electric actuator, and controller. This effectively prevents chlorine leakage caused by excessive gas pressure.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
