[0002] Chemical industrial safety production refers to ensuring the safety of personnel, preventing accidents, and maintaining production order during the production process of chemical products through a series of measures and regulations. Generally speaking, chemical industrial safety production requires eliminating unsafe factors in the production process, creating a good, safe and comfortable working environment and order, preventing accidents and occupational diseases, and ensuring the safety and health of employees.

[0003] Among them, the core of chemical industrial safety production is to turn danger into safety. For example, when using chemical pipelines, flammable and explosive gases need to be transported. Therefore, if the flame retardant and fire prevention effects are not good, dangerous phenomena such as pipeline explosions are likely to occur directly, which can easily endanger the lives of workers and directly affect the construction of chemical industrial safety production. Content of the Utility Model

[0004] The purpose of the utility model is to provide an explosion-proof strengthening structure for pipelines in chemical industrial safety production, so as to solve the problem proposed in the above background technique that when using chemical pipelines, flammable and explosive gases need to be transported. Therefore, if the flame retardant and fire prevention effects are not good, dangerous phenomena such as pipeline explosions are likely to occur directly, which can easily endanger the lives of workers and directly affect the construction of chemical industrial safety production.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An explosion-proof strengthening structure for pipelines in chemical industrial safety production, including a flame retardant ring, a connecting ring, and a safety chemical pipeline. An intensifying cavity is formed inside the flame retardant ring, a flame retardant and fire prevention layer is fixed inside the flame retardant ring, a first reinforcing rod is fixed inside the intensifying cavity, connecting rods are fixed at the front and rear ends of the first reinforcing rod, and a protective layer is fixed on the outer side wall of the flame retardant ring.

[0006] Preferably, the first reinforcing rods are evenly distributed inside the intensifying cavity, and the connecting rods are symmetrically distributed about the central axis of the first reinforcing rod.

[0007] Preferably, two groups of connecting rods are installed between the first reinforcing rods, and a welded fixation is formed between the first reinforcing rod and the connecting rod.

[0008] Preferably, the protective layer includes a wear-resistant layer and an anti-corrosion layer. The anti-corrosion layer is coated on the outer side wall of the flame retardant ring, and the wear-resistant layer is fixed on the outer side wall of the anti-corrosion layer.

[0009] Preferably, the coated surface areas of the wear-resistant layer and the anti-corrosion layer are the same, and the wear-resistant layer and the anti-corrosion layer are coated on the same vertical section.

[0010] Preferably, mounting pieces are fixed to both the top end and the bottom end of the flame retardant ring, and through holes are formed inside the mounting pieces.

[0011] Preferably, the mounting pieces are symmetrically distributed about the central axis of the flame retardant ring, a pin is passed through the inside of the through hole, and a locking nut is connected to the outer side wall of the pin.

[0012] Preferably, external threads are fixed to the outer side walls on both sides of the pin, a threaded connection is formed between the locking nut and the pin, and the locking nuts are symmetrically distributed about the central axis of the pin.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: This pipeline explosion-proof strengthening structure for chemical industrial safety not only improves the flame retardant and strengthening ability, but also simultaneously improves the docking and positioning ability and the protection ability of this pipeline explosion-proof strengthening structure;

[0014] (1) Through the formation of the strengthening cavity inside the flame retardant ring and the filling of a flame retardant and fire blocking layer inside the flame retardant ring, therefore, with the addition of the flame retardant and fire blocking layer, an effect of internal and external flame retardant protection of the flame retardant ring is formed. At the same time, first strengthening rods are evenly distributed inside the strengthening cavity. Therefore, after the first strengthening rods are evenly distributed, the overall support and strengthening ability is preferably improved. At the same time, two first strengthening rods are connected by an adapter rod. Therefore, the first strengthening rod improves the stability of the adapter rod, thereby preferably improving the overall flame retardancy and anti-deformation ability during the working process;

[0015] (2) By installing and fixing the mounting pieces at the upper and lower positions of the flame retardant ring, therefore, when two flame retardant rings are assembled, since through holes are formed inside the mounting pieces, the pin is passed through the through holes of the mounting pieces at the top of the two flame retardant rings. After connection, the position of the pin is locked by a locking nut, thereby preferably improving the overall docking and positioning ability during the working process;

[0016] (3) By fixing the protective layer to the outside of the flame retardant ring, and this protective layer includes a wear-resistant layer and an anti-corrosion layer. The anti-corrosion layer is coated on the outer side wall of the flame retardant ring to form anti-corrosion protection, and the wear-resistant layer is coated on the outer side wall of the anti-corrosion layer. Therefore, after the wear-resistant layer is exposed to the outside, an external wear-resistant protection is formed, thereby preferably improving the service life of the flame retardant ring during the working process.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present utility model: An explosion-proof strengthening structure for a chemical production safety pipeline, including a flame-retardant ring 1, a connecting ring 4, and a safe chemical pipeline 6. A strengthening cavity 8 is formed inside the flame-retardant ring 1, a flame-retardant and fire-blocking layer 7 is fixed inside the flame-retardant ring 1, a first strengthening rod 9 is fixed inside the strengthening cavity 8, connecting rods 10 are fixed at the front and rear ends of the first strengthening rod 9, and a protective layer 11 is fixed on the outer side wall of the flame-retardant ring 1.

[0024] The first strengthening rods 9 are evenly distributed inside the strengthening cavity 8, and the connecting rods 10 are symmetrically distributed about the central axis of the first strengthening rod 9.

[0025] Two groups of connecting rods 10 are installed between the first strengthening rods 9, and the first strengthening rod 9 and the connecting rod 10 are fixedly connected by welding.

[0026] The protective layer 11 includes a wear-resistant layer 13 and an anti-corrosion layer 14. The anti-corrosion layer 14 is coated on the outer side wall of the flame-retardant ring 1, and the wear-resistant layer 13 is fixed on the outer side wall of the anti-corrosion layer 14.

[0027] The coating surface areas of the wear-resistant layer 13 and the anti-corrosion layer 14 are the same, and the wear-resistant layer 13 and the anti-corrosion layer 14 are coated on the same vertical cross-section.

[0028] Mounting pieces 3 are fixed at both the top and bottom ends of the flame-retardant ring 1, and through holes 12 are opened inside the mounting pieces 3.

[0029] The mounting pieces 3 are symmetrically distributed about the central axis of the flame-retardant ring 1, a pin 2 penetrates through the inside of the through hole 12, and a locking nut 5 is connected to the outer side wall of the pin 2.

[0030] External threads are fixed on the outer side walls on both sides of the clamping pin 2, and a threaded connection is formed between the locking nut 5 and the clamping pin 2. The locking nuts 5 are symmetrically distributed about the central axis of the clamping pin 2;

[0031] Furthermore, the wear-resistant layer 13 can be formed by using a ceramic coating for wear-resistant protection, and the anti-corrosion layer 14 can be protected against corrosion by using anti-corrosion paint;

[0032] Furthermore, when the two flame-retardant rings 1 are connected, a sealing ring can be added at the contact surface to reduce the wear problem during contact.

[0033] Working principle: First, during operation, the protective layer 11 is fixed outside the flame-retardant ring 1.

The anti-corrosion layer 14 is coated on the outer side wall of the flame-retardant ring 1 to form anti-corrosion protection, and the wear-resistant layer 13 is coated on the outer side wall of the anti-corrosion layer 14. Therefore, after the wear-resistant layer 13 is exposed outside, external wear-resistant protection is formed. Then, after the safety chemical pipeline 6 is connected by the connecting ring 4, the two flame-retardant rings 1 are used to complete the splicing with each other. Then, the clamping pin 2 passes through the through hole 12 of the mounting piece 3 at the top of the two flame-retardant rings 1. After connection, the locking nut 5 is used to lock the position of the clamping pin 2, so that the flame-retardant ring 1 forms flame-retardant and explosion-proof protection.
