Description

Technical Field

[0001] This invention belongs to the field of ultra-high pressure vessel cylinders, and specifically discloses an assembled cylinder. Background Technology

[0002] Existing ultra-high pressure cylinders are formed using blow molding or injection molding. This method involves molding the cylinder bottom and body in a single step, requiring the creation of molds for cylinders of different sizes. This results in a higher unit price and overall higher cost for smaller batches. Furthermore, increased material thickness is needed at the transition between the cylinder bottom and body, and at the cap connection, to ensure pressure resistance and drop resistance. This affects the cylinder's volumetric efficiency. Additionally, the cap typically needs to be molded separately.

[0003] The existing molding method has the following drawbacks: 1. For products with small batches, the unit price is high because molds need to be made, and new molds need to be made when changing product specifications, which increases costs.

[0004] 2. The material thickness needs to be increased at the transition between the bottom of the cylinder and the body of the cylinder, as well as at the connection of the cylinder cover, to ensure pressure resistance and drop resistance, which affects the volume ratio of the cylinder.

[0005] 3. The cylinder cap needs to be molded separately, requiring a separate mold, which results in higher costs. Summary of the Invention

[0006] This invention addresses the problems of existing one-piece molded material cylinders, which suffer from non-interchangeability between the cylinder body and cap, high cost, poor adaptability to product specifications, and large material thickness affecting volumetric efficiency and performance. It proposes an assembled material cylinder. This invention increases the volumetric efficiency of the material cylinder and enhances the strength of the bottom and cap areas without increasing material volume, thus preventing damage to the cylinder due to impact.

[0007] Meanwhile, the bottom and cover of the barrel are interchangeable, reducing usage costs.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an assembled material cylinder, comprising: A cylindrical body having a receiving cavity, with openings spaced apart on the body of the cylinder; The bottom of the cylinder is connected to the cylinder body by assembly welding. The cylinder cover includes a cover body and a connector. The cover body has multiple lower toothed plates distributed in a ring, and the connector has upper toothed plates distributed in a ring corresponding to the lower toothed plates. The cover body is detachably connected to one side of the connector through the lower toothed plates and the upper toothed plates, and the other side of the connector is connected to the cylinder body by assembly welding.

[0009] Furthermore, the bottom of the cylinder has a first circular hole evenly distributed along the circumference on its side wall, and a second circular hole is pre-set on one side of the cylinder body. After the bottom of the cylinder is inserted into the cylinder body, the first circular hole and the second circular hole correspond one to one. The rivet is inserted into the first circular hole and the second circular hole to connect the bottom of the cylinder and the cylinder body.

[0010] Furthermore, the side wall of the connector is pre-set with a first circular hole evenly distributed along the circumference, and the other side of the cylinder is pre-set with a second circular hole. After the connector is inserted into the cylinder, the first circular hole and the second circular hole correspond one to one. The rivet is inserted into the first circular hole and the second circular hole to connect the connector and the cylinder.

[0011] Furthermore, the rivet block is welded and fixed to the bottom of the cylinder or the joint.

[0012] Furthermore, the diameter of the second circular hole is larger than the diameter of the first circular hole, and the rivet block is stepped.

[0013] Furthermore, the upper and lower jaw plates are provided with helical self-locking inclined surfaces, which connect the joint to the cover.

[0014] Furthermore, water inlet holes are provided at the bottom of the cylinder and the bottom of the cylinder cover, as well as on the cylinder body.

[0015] Furthermore, the cylinder body is provided with openings spaced apart.

[0016] Compared with the prior art, the innovations and advantages of this invention are reflected in the following aspects: 1. The cylinder body of the present invention is made of common specifications of polymer tubing, and the production batch has little impact on the cost. The bottom and top of the cylinder are processed separately and then assembled with the cylinder body.

[0017] 2. The bottom of the cylinder is connected to the cylinder body and the cylinder cover by an assembly method. Therefore, the bottom of the cylinder, the cylinder body and the cylinder cover can be made separately and connected by machining and mechanical connection methods. They have good interchangeability and the bottom of the cylinder, the cylinder body and the cylinder cover can be made of suitable materials. The cylinder body and the cylinder cover are obtained by common machining methods, which are suitable for products of different specifications and have low cost.

[0018] 3. The cylinder and cylinder cover obtained by machining have controllable precision, good self-locking conditions, small torque when the cylinder and cylinder cover are screwed or opened, and good performance.

[0019] 4. The bottom and cover of the cylinder are made of a thinner material, which reduces the material volume and ensures that the bottom and cover fit snugly against the sides of the cylinder body, effectively reducing the space occupied by the bottom and cover and thus increasing the volume ratio of the cylinder.

Detailed Implementation

[0029] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0030] like Figure 1 As shown, an assembled material cylinder includes a cylinder body 1, a cylinder bottom 2, and a cylinder cover 3. The cylinder body 1 is assembled with the cylinder bottom 2 and the cylinder cover 3. The cylinder body 1 has a receiving cavity 11 for placing the material to be processed, and side openings 12 are spaced apart on the cylinder body, which serve as loading ports for the material to be processed.

[0031] like Figure 2 As shown, the bottom 2 and the body 1 are connected by assembly welding. Figure 6 As shown, a first circular hole 35 is pre-set on the side wall of the bottom of the cylinder 2, evenly distributed along the circumference, and a second circular hole 13 is pre-set on one side of the cylinder body 1. After the bottom of the cylinder 2 is inserted into the cylinder body 1, the first circular hole 35 and the second circular hole 13 correspond one-to-one. The rivet 4 is inserted into the first circular hole 35 and the second circular hole 13 to connect the bottom of the cylinder 2 and the cylinder body 1. The rivet 4 is welded and fixed to the bottom of the cylinder 2, thereby connecting the bottom of the cylinder 2 and the cylinder body 1.

[0032] To facilitate the welding and fixing of the rivet 4, the diameter of the second circular hole 13 is larger than the diameter of the first circular hole 35, and the rivet 4 is stepped. This way, after the stepped rivet 4 is inserted into the first circular hole 35 and the second circular hole 13, the bottom of the cylinder 2 can be connected to the cylinder body 1, and the rivet 4 will not fall out, facilitating subsequent welding and fixing of the rivet 4.

[0033] like Figure 4 As shown, the cap 3 includes a cap body 31 and a connector 32. Multiple lower toothed plates 33 are distributed in a ring on the cap body 31, and upper toothed plates 34 corresponding to the lower toothed plates 33 are distributed in a ring on the connector 32. The cap body 31 and the connector 32 are detachably connected by the upper toothed plates 34 and the lower toothed plates 33.

[0034] To increase connection stability, the upper toothed plate 34 and the lower toothed plate 33 are provided with helical self-locking inclined surfaces, which connect the connector 32 to the cover 31. In addition to the helical self-locking inclined surfaces, a gradually decreasing clamping surface can also be used to lock the upper toothed plate 34 and the lower toothed plate 33.

[0035] The connector 32 is connected to the other side of the cylinder 1 by assembly welding. Figure 5 As shown, the side wall of the connector 32 is provided with a first circular hole 35 evenly distributed along the circumference, and the other side of the cylinder 1 is provided with a second circular hole 13. After the connector 32 is inserted into the cylinder 1, the first circular hole 35 and the second circular hole 13 correspond one to one. The rivet 4 is inserted into the first circular hole 35 and the second circular hole 13 to connect the connector 32 and the cylinder 1.

[0036] In addition, such as Figure 8 As shown, water inlet holes 5 are provided at the bottom of the cylinder bottom 2 and the bottom of the cylinder cover 3, as well as on the cylinder body 1, to facilitate the entry of high-pressure water into the cylinder body 1 to complete the ultra-high pressure treatment of the material.

[0037] It is understood that the above specific description of the present invention is only for illustrating the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of the present invention.
