Description

Technical Field

[0001] This utility model relates to a centrifuge with small diameter and long tube processing, belonging to the field of mechanical equipment. Background Technology

[0002] Centrifuges are often used in the processing of pipe fittings. Currently, most centrifuges are equipped with a casting machine to inject molten iron into the pipe mold. In view of this, a hot mold centrifugal casting machine is disclosed in the patent document with application number 201910807460.8. The above-mentioned prior art uses a casting machine for casting. When processing pipe fittings with small diameter and long length (diameter DN400~1000, length 7~11m), if a casting machine is used for casting, the working efficiency is low. After casting is completed, the temperature of the molten iron will also drop, which will affect the quality of the pipe fittings. In addition, the casting machine requires a large stroke and occupies a large space. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the existing technology and to provide a centrifuge with a reasonable structural design and small diameter and long tube processing.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: the centrifuge with small diameter and long pipe processing includes a centrifuge host, a drive roller is provided at both the front and rear ends of the centrifuge host, and a stop roller is provided at the front or rear end of the centrifuge host. Its structural feature is that at least one pressure roller mechanism is provided between the two drive rollers. The pressure roller mechanism includes a pressure roller frame, a roller swing arm, a roller, a pressure roller swing arm, and a pressure roller. One end of the roller swing arm and the pressure roller swing arm are both installed on the pressure roller frame, and the roller and the pressure roller are respectively installed at the other end of the roller swing arm and the pressure roller swing arm.

[0005] Furthermore, a casting machine is installed at both the front and rear ends of the centrifuge unit.

[0006] Furthermore, the pressure roller mechanism also includes a support roller adjusting rod and a pressure roller adjusting rod, both of which are mounted on the pressure roller frame and are in contact with the support roller swing arm and the pressure roller swing arm, respectively.

[0007] Furthermore, there are two support rollers, which are symmetrically arranged, and the pressure roller is located above the two support rollers.

[0008] Furthermore, the centrifuge unit is located inside a protective cover.

[0009] Compared with the prior art, this utility model has the following advantages: the centrifuge can be used to process pipes with small diameter and long length. By equipping a casting machine at each end of the centrifuge host, casting can be carried out at both ends of the pipe mold at the same time, so as to improve casting efficiency and shorten the stroke of the casting machine to save space. At the same time, setting at least one pressure roller mechanism between the two sets of drive rollers can ensure the concentricity of the pipe mold and prevent the pipe mold from jumping out when rotating at high speed.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] Example

[0019] See Figures 1 to 6As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0020] The centrifuge for processing small-diameter, long pipes in this embodiment includes a centrifuge host 1 located inside a protective cover 3, a casting machine 2 at each of the front and rear ends outside the centrifuge host 1, a drive roller 12 at each of the front and rear ends inside the centrifuge host 1, and a baffle roller 11 at the front or rear end inside the centrifuge host 1.

[0021] At least one pressure roller mechanism 13 is provided between the two drive rollers 12. The pressure roller mechanism 13 includes a pressure roller frame 131, a roller swing arm 132, a roller 133, a roller adjusting rod 134, a pressure roller swing arm 135, a pressure roller 136, and a pressure roller adjusting rod 137. There are two rollers 133, which are symmetrically arranged. The pressure roller 136 is located above the two rollers 133.

[0022] In this embodiment, one end of the support roller swing arm 132 and the pressure roller swing arm 135 are both mounted on the support roller frame 131, the support roller 133 and the pressure roller 136 are respectively mounted on the other end of the support roller swing arm 132 and the pressure roller swing arm 135, the support roller adjusting rod 134 and the pressure roller adjusting rod 137 are both mounted on the support roller frame 131, and the support roller adjusting rod 134 and the pressure roller adjusting rod 137 are in contact with the support roller swing arm 132 and the pressure roller swing arm 135 respectively.

[0023] Specifically, this centrifuge can be used to process pipes with diameters of DN400-1000 and lengths of 7-11m. These pipes are commonly used in the papermaking industry. When processing pipes with smaller diameters and longer lengths, casting can be performed simultaneously at both ends of the mold to improve casting efficiency and reduce the stroke of the casting machine 2, thereby saving space. At least one drive roller 12 is provided between the two drive rollers 12 to prevent the mold from being too long. Due to the weight of the mold, the roller 133 may not be able to keep concentric with the front and rear sets of drive rollers 12. During high-speed rotation, the mold may jump and fly out, causing a safety accident. The function of the roller 133 is to ensure concentricity with the front and rear sets of drive rollers 12 when the mold is sags due to its own weight. The function of the pressure roller 136 is to prevent the mold from jumping and flying out.

[0024] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model are included within the protection scope of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined by the claims, all of which should fall within the protection scope of this utility model.
