Description

Technical Field:

[0001] The utility model relates to the field of calcium carbide production and processing, and particularly relates to an automatic furnace door air source switch system. Background Art:

[0002] Calcium carbide, also known as calcium acetylide, is an inorganic compound. It is a white crystal, and the industrial product is a grayish-black lump with a purple or gray cross-section. It reacts violently with water immediately, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used for generating acetylene gas.

[0003] It is also used in organic synthesis, oxyacetylene welding, etc.

[0004] With the wide application of automatic furnace doors in the calcium carbide industry, different problems have emerged in different enterprises due to different installation positions (different installation distances between the control box and the furnace door). The more concentrated problem is that the air path is too long. When compressed air reaches the pneumatic motor through the air source pipe, the pressure and flow rate decrease, making it impossible to drive the air motor to work, resulting in the automatic furnace door being unable to open or close.

[0005] Therefore, a switch system that can solve the problem of opening and closing the aluminum door is needed. Content of the Utility Model:

[0006] The purpose of the utility model is to provide an automatic furnace door air source switch system.

[0007] The utility model is implemented by the following technical solutions:

[0008] An automatic furnace door air source switch system includes an air source, a quick exhaust valve, and a pneumatic motor. The output end of the air source is fixedly connected and communicated with the input end of the quick exhaust valve. The output end of the quick exhaust valve is fixedly connected and communicated with the input end of the pneumatic motor. A sealing cover is fixedly installed at each port of the quick exhaust valve. A water tank is fixedly installed at the top of the sealing cover. A through hole is fixedly provided at the top of the sealing cover, and the through hole is communicated with the bottom end of the water tank. A one-way valve is fixedly installed in the through hole.

[0009] Preferably, a sealing ring is fixedly connected to one side of the sealing cover. A push switch is fixedly installed on the inner wall of one side of the sealing ring. A moving ring connected in a sliding manner is inserted into the sealing cover. An installation groove is provided on the inner wall of the moving ring. A pressing ring is slidably connected in the installation groove. Two pressing rods are fixedly installed on the side wall of each pressing ring. One end of each pressing rod passes through the moving ring and is slidably connected with it. A sealing airbag is installed in the installation groove.

[0010] Preferably, two guiding rods are fixedly connected to one end of the moving ring, and the two guiding rods respectively pass through the sealing ring and are slidably connected with it.

[0011] Advantages of the present utility model: If there are small leakage points, after the gas enters the sealing cover, it will flow into the water tank along the through holes, resulting in the generation of bubbles in the water tank. Therefore, in the central control room, it can be detected through the camera, facilitating the maintenance personnel to carry out maintenance. If there is a sudden air leakage, the internal air pressure will suddenly increase, causing the moving ring to move, so that the pressing rod contacts the inner wall of the sealing ring, and the sealing airbag is further pressed under the action of the pressing ring to achieve the function of emergency leak stoppage. At the same time, the pressing switch will be pressed, causing the pipeline solenoid valve above the water tank to close, achieving re-sealing, and triggering an alarm to notify the maintenance personnel to carry out maintenance in a timely manner. Brief Description of the Drawings:

[0012] Figure 1 is a schematic diagram of the structure of the present utility model;

[0013] Figure 2 is a schematic diagram of the system flow of the present utility model.

[0014] In the figure: air source 1, quick exhaust valve 2, pneumatic motor 3, sealing cover 4, water tank 5, through hole 6, sealing ring 7, moving ring 8, mounting groove 9, pressing ring 10, pressing rod 11, sealing airbag 12, guide rod 13, pressing switch 14. Specific Embodiment:

[0015] As Figures 1 to 2 shown, an automatic furnace door air source switch system includes an air source 1, a quick exhaust valve 2, and a pneumatic motor 3. The output end of the air source 1 is fixedly connected and communicated with the input end of the quick exhaust valve 2, and the output end of the quick exhaust valve 2 is fixedly connected and communicated with the input end of the pneumatic motor 3. Sealing covers 4 are fixedly installed at each port of the quick exhaust valve 2. The top of the sealing cover 4 is fixedly installed with a water tank 5. The top of the sealing cover 4 is fixedly provided with a through hole 6, and the through hole 6 communicates with the bottom end of the water tank 5. A one-way valve is fixedly installed in the through hole 6. The quick exhaust valve 2 can make the movement of the cylinder faster and more frequent, thus solving the problem of insufficient pressure. When there are fine leakage points at the interface, the gas flows in the sealing cover 4 and then enters the water tank 5 through the through hole 6, resulting in the appearance of water bubbles in the water tank 5. In this way, the operator can observe through the camera in the central control room to determine whether to carry out maintenance work, reducing the labor intensity of the operator and avoiding the operator walking around frequently to check, realizing automatic monitoring.

[0016] One side of the sealing cover 4 is fixedly connected with a sealing ring 7. A pressing switch 14 is fixedly installed on the inner wall of one side of the sealing ring 7. A moving ring 8 connected in a sliding manner is inserted into the sealing cover 4. An installation groove 9 is arranged on the inner wall of the moving ring 8. A pressing ring 10 is connected in a sliding manner in the installation groove 9. Two pressing rods 11 are fixedly installed on the side wall of each pressing ring 10. One end of each pressing rod 11 passes through the outside of the moving ring 8 and is slidably connected therewith. A sealing airbag 12 is installed in the installation groove 9. When there is acute air leakage at the interface due to pressure reasons, since one side of the moving ring 8 is tightly sealed with the interface, at the moment of air pressure leakage, it will cause the moving ring 8 to move, so that one side of the moving ring 8 contacts the sealing ring 7. When the two pressing rods 11 contact, they will cause the pressing ring 10 to press the sealing airbag 12, making the sealed part more tight and reducing gas leakage. Thus, the pressing switch 14 will start to work, causing the pipeline solenoid valve at the top of the water tank 5 to close, realizing re-sealing, ensuring the normal closing of the furnace door, and then carrying out maintenance.

[0017] Two guide rods 13 are fixedly connected to one end of the moving ring 8. The two guide rods 13 respectively pass through the sealing ring 7 and are slidably connected therewith. The guide rods 13 play a guiding role, making the movement of the moving ring 8 more stable.

[0018] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
