Description

Technical Field

[0001] This utility model relates to the technical field of spray gun caps, specifically a structure for a natural gas spray gun cap in a melting section. Background Technology

[0002] In photovoltaic glass production, gas torches are used to provide a high-temperature heat source to promote the rapid melting of raw materials. When using gas torches to provide heat, a torch cap structure is needed to adjust the flame for uniform dispersion.

[0003] There are many types of existing natural gas nozzle caps, but they still have certain shortcomings in use. Loosening is very likely to occur during nozzle positioning and installation. To solve this problem, a natural gas nozzle disclosed in existing technology (Chinese patent application number CN201720448814.0, publication date 2017-12-01) can be referenced. This natural gas nozzle uses a dispersion cap to ensure more uniform gas mixing in the mixing chamber, guaranteeing flame stability; a guide plate and guide holes ensure the airflow intensity of gas entering the steel pipe; and a flexible hose connects the mixing chamber and the steel pipe, which is more conducive to nozzle positioning.

[0004] Although the above-mentioned device can solve the positioning problem, it still has certain shortcomings. When installing the gun cap and the nozzle, the gas ejection will cause local vibration, which can easily cause the gun cap and the nozzle to fall off, thus potentially posing a danger during operation.

[0005] Therefore, we proposed that the structure of the natural gas nozzle cap in the melting section can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a natural gas nozzle cap structure for a melting section, in order to solve the problem mentioned in the background art that when the nozzle cap and nozzle are installed in the current market, the local vibration caused by the gas ejection can easily lead to the nozzle cap and nozzle falling off, which may pose certain dangerous factors during operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a natural gas nozzle cap structure for a melting section, comprising a nozzle cap body, wherein a plurality of vents are provided on the outer side of the upper surface of the nozzle cap body, and a nozzle body is connected to the bottom of the nozzle cap body; a locking disc is fixed on the outer side of the upper end of the nozzle body, and the locking disc has an insertion hole at an equal angle about the center of the locking disc, the insertion hole and the locking mechanism being configured to achieve a stable connection between the nozzle cap body and the nozzle body; a tension member is also provided above the locking mechanism, and the outer side of the upper end of the tension member is fixed to the outer side of the nozzle cap body.

[0010] As a preferred technical solution of this application, the tensioning member includes a movable rod fixed at the top position of the sliding ring, the upper outer side of the movable rod is also fixedly connected to the bottom of the return spring, the top of the return spring is fixed to the upper inner side of the vertical cylinder, and the upper outer side of the vertical cylinder is connected to the outer position of the gun cap body through a fixing block.

[0011] As a preferred technical solution of this application, a spiral groove is also provided on the inner side of the embedding hole, and six sets of the embedding hole are provided at equal angles with respect to the center of the locking disc.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The natural gas nozzle cap structure of the melting section is equipped with a locking mechanism. This locking mechanism allows the locking block to fit snugly against the bottom outer side of the locking disc, preventing the nozzle cap body from detaching from the nozzle body.

All undesirable atmospheres such as cross flame, scorching flame, and figure-eight flame are corrected, laying a solid foundation for stable production and improved efficiency. In addition, the gun cap body can be more tightly embedded in the baffle plate, realizing flexible adjustment of the flame angle.

[0015] 2. A locking mechanism is provided. By pushing the sliding ring, the embedded rod at the bottom of the sliding ring can drive the embedded hole to move through the locking block.

[0023] 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.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: Example

[0025] For easier use of the gun cap body 1, please refer to the attached document. Figure 1 -Appendix Figure 3 The gun includes a cap body 1, with several sets of ventilation ports 2 on the outer side of the upper surface of the cap body 1, and a nozzle body 3 connected to the bottom of the cap body 1. A locking disc 4 is fixed to the outer side of the upper end of the nozzle body 3. An insertion hole 5 is provided at an equal angle to the center of the locking disc 4. The insertion hole 5 and the locking mechanism are designed to achieve a stable connection between the cap body 1 and the nozzle body 3. The outer side of the upper end of the nozzle body 3 is threaded, and a threaded connection port 101 is provided on the inner side of the bottom of the cap body 1. The threaded connection port 101 is threaded to the outer side of the upper end of the nozzle body 3.

[0026] First, by rotating the top of the nozzle body 3 through the threaded connection port 101 at the bottom of the nozzle body 1, the nozzle body 1 can be threadedly connected to the top outer side of the nozzle body 3 through the threaded connection port 101. When the nozzle body 3 is filled with natural gas and compressed gas and mixed and injected, the gas will be jetted through the nozzle body 3. And through the set vent 2, the outside air can be mixed, so that the gas can be fully combusted. Furthermore, by increasing the inner diameter of the nozzle body 1, the flame coverage range is increased, and the flame length reaches 2 / 3 of the kiln span. All undesirable atmospheres such as cross flame, scorching flame, and figure-eight flame are corrected, laying a solid foundation for stable production and improved efficiency. In addition, the nozzle body 1 can be more tightly embedded in the baffle plate, realizing flexible adjustment of the flame angle. Example

[0027] To address the issue that during the installation of gun caps and nozzles in the current market, localized vibrations caused by gas ejection can easily lead to the cap and nozzle detaching from each other, potentially posing a safety hazard during operation, please refer to the attached document. Figure 1 -Appendix Figure 6The insertion hole 5 and the locking mechanism achieve a stable connection between the gun cap body 1 and the muzzle body 3. A tension member 11 is also provided above the locking mechanism, with its upper outer end fixed to the outer side of the gun cap body 1. The locking mechanism includes a sliding ring 7 slidably disposed on the outer side of the gun cap body 1. An insertion rod 8 is rotatably disposed at the bottom of the sliding ring 7, with a spiral pattern 9 in the lower middle part of the insertion rod 8. A locking block 10 is also fixed at the bottom of the insertion rod 8. A tension member 11 is also provided at the upper end of the sliding ring 7. The tension member 11 includes a moving rod 11 fixed at the top of the sliding ring 7. 04. The upper outer side of the moving rod 1104 is also fixedly connected to the bottom of the return spring 1103. The top of the return spring 1103 is fixed to the upper inner side of the vertical cylinder 1102. The upper outer side of the vertical cylinder 1102 is connected to the outer side of the gun cap body 1 through the fixing block 1101. The inner side of the embedding hole 5 is also provided with a spiral groove 6. The embedding hole 5 is provided with six sets of grooves at equal angles about the center of the locking disc 4. The outer wall size of the locking block 10 is smaller than the inner wall size of the embedding hole 5. The outer side of the spiral pattern 9 and the inner side of the spiral groove 6 are spirally connected. The embedding rod 8 forms a rotating structure through the spiral pattern 9 and the spiral groove 6.

[0028] After the cap body 1 and the nozzle body 3 are threaded together via the threaded connection port 101, pressing the sliding ring 7 will cause the insert rod 8 to move. At this time, the spiral 9 and locking block 10 on the lower outer side of the insert rod 8 will move into the insert hole 5. When the outer side of the locking block 10 is inserted into the bottom of the insert hole 5, the sliding ring 7 is further pressed. Since the insert rod 8 and the spiral groove 6 are spirally connected, the insert rod 8 will rotate at the lower end of the locking disc 4, allowing the bottom of the locking block 10 to fit against the inner side, preventing it from falling off. At this time, the spiral... 9 will rotate halfway between the inner sides of the spiral groove 6, that is, the locking block 10 will rotate 180°. When replacement is needed, continue to squeeze the sliding ring 7. Then the sliding ring 7 will continue to drive the spiral 9 to make a spiral connection with the spiral groove 6. At this time, the locking block 10 can be rotated to the bottom of the embedded hole 5, and the sliding ring 7 is released. The return spring 1103 set inside the tension member 11 will be reset, which will cause the vertical cylinder 1102 and the moving rod 1104 to move back to their original positions. The sliding ring 7 can be fitted and limited, thereby preventing the gun cap body 1 from falling off the vent 2.
