[0001] The utility model relates to the technical field of elbow pipe fittings, in particular to a wear-resistant elbow. Background Art

[0002] At present, pneumatic conveying is usually used to transport raw materials for mortar products. Pneumatic conveying is also called air flow conveying, which uses the flow rate of air flow to transport granular materials in the direction of air flow in a closed pipeline. This type of conveying method has the advantages of large conveying volume, long conveying distance, and high conveying speed, but it also has the problems of large energy consumption, granular materials are easily damaged, and pipelines are easily corroded. Especially the elbows at the turning parts of the pipeline, the elbows are most susceptible to abrasion, and the pipeline needs to be stopped for inspection and replacement, resulting in certain economic losses.

[0003] The existing elbows on the market include jacketed tube elbows, ceramic elbows, backpack elbows, etc. Although these elbows are wear-resistant, they are expensive and the problem of granular materials being damaged at the elbows is not easy to solve. In view of the above phenomenon, the inventor proposes an elbow with simple structure and high practicality. Utility Model Content

[0005] The utility model provides a wear-resistant elbow, which adopts the following technical solution:

[0010] Preferably, the baffle is made of stainless steel.

[0011] Preferably, the central axis of the feed pipe is perpendicular to the central axis of the discharge pipe.

[0012] Preferably, flanges are respectively provided at the ends of the feed pipe and the discharge pipe away from the cylinder.

[0013] In summary, the utility model includes the following beneficial technical effects:

[0014] 1. By arranging baffles on the side walls of the chamber of the cylinder, and multiple groups of baffles are arranged, a storage trough is formed between each two adjacent groups of baffles, and the cylinder is welded with a baffle for shielding the chamber. When the granular material is conveyed from the feed cylinder to the chamber of the cylinder, the flowing granular material first fills up the storage troughs located in the middle and bottom of the cylinder. When the subsequent granular material is conveyed to the front chamber, it collides with the material in the storage trough, so that the friction between the granular material and the inner wall of the cylinder during the conveying process is converted into friction between the materials. On the one hand, the wear of the elbow is reduced, and on the other hand, the damage of the material is reduced. In addition, the structure is simple and can be processed and manufactured by oneself.

[0015] 2. By opening a buffer groove on the baffle wall, the retention time of the material on the baffle is prolonged, so that the material can be stored on the baffle in an inclined state.

[0016] 3. By setting the baffle plate toward the center of the chamber so that the thickness dimension gradually decreases, the area of ​​direct contact between the baffle plate and the material is reduced, thereby reducing the damage of the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is combined with Figure 1-3 The utility model is described in further detail.

[0022] The utility model discloses a wear-resistant elbow. Figure 1, including a cylinder 1, a chamber 11 is opened inside the cylinder 1, a feed pipe 2 and a discharge pipe 3 connected with the chamber 11 are welded to the circumferential side wall of the cylinder 1, the central axes of the feed pipe 2 and the discharge pipe 3 are in a vertical relationship, and flanges 21 are welded to the ends of the feed pipe 2 and the discharge pipe 3 away from the cylinder 1; the chamber 11 is in a state of penetrating the opposite side walls of the cylinder 1, and baffles 12 for shielding the chamber 11 are welded to the opposite side walls of the cylinder 1.

[0023] Reference Figure 2 The cross-section of the chamber 11 is circular, and a baffle 4 is welded to the circumferential inner wall of the chamber 11. The baffle 4 is made of stainless steel. The length direction of the baffle 4 is consistent with the direction in which the chamber 11 passes through. There are multiple groups of baffles 4, and the multiple groups of baffles 4 are arranged on the inner wall of the chamber 11. The side wall of the chamber 11 has a space connected to the feed pipe 2 and the discharge pipe 3. Each two adjacent groups of baffles 4 form a storage trough 121. When the granular material is transported from the feed barrel to the chamber 11 of the barrel 1, the flowing granular material first fills the storage trough 121 located in the middle and bottom positions of the barrel 1, and the granular material subsequently transported to the chamber 11 collides with the material in the storage trough, reducing the direct contact between the granular material and the inner wall of the chamber 11. On the one hand, it reduces the abrasion of the inner wall of the chamber 11, and on the other hand, it reduces the damage of the material caused by direct collision with the side wall of the chamber 11.

[0024] Reference Figure 2 and Figure 3 Buffer grooves 41 are respectively provided on the opposite side walls of the baffle 4, and the length direction of the buffer grooves 41 is consistent with the length direction of the baffle 4, and multiple groups of buffer grooves 41 are arranged, and the multiple groups of buffer grooves 41 are evenly arranged on the wall of the baffle 4. The setting of the buffer grooves 41 enhances the friction force of the wall of the baffle 4, thereby prolonging the residence time of the granular material on the baffle 4 in the downward inclined state, so that the granular material subsequently transported to the chamber 11 can collide with the material in the storage trough 121.

[0025] Reference Figure 3 The thickness of the baffle plate 4 at one end toward the center of the chamber 11 gradually decreases. This structure reduces the contact area between the end of the baffle plate 4 and the granular material, thereby reducing the direct collision between the granular material and the end of the baffle plate 4.

[0026] The implementation principle of a wear-resistant elbow in the embodiment of the utility model is as follows:

[0027] When manufacturing the elbow, the feed pipe 2 and the discharge pipe 3 connected to the chamber 11 are welded on the circumferential side wall of the cylinder 1, the processed baffle 4 is welded to the inner wall of the chamber 11 of the cylinder 1, and then the baffle 12 is welded to the opposite side walls of the cylinder 1; when the granular material is transported from the feed cylinder to the chamber 11 of the cylinder 1, the flowing granular material first fills the storage trough 121 located in the middle and bottom of the cylinder 1, and the granular material subsequently transported to the chamber 11 collides with the material in the storage trough 121, thereby reducing the direct contact between the granular material and the inner wall of the chamber 11. On the one hand, it reduces the abrasion of the inner wall of the cylinder 1, and on the other hand, it reduces the damage of the material caused by direct collision with the side wall of the chamber 11. At the same time, this structure is simple, can be processed and manufactured by itself, and is economical and practical.

[0028] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
