Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal steam compressors, in particular to an air intake baffle of a centrifugal steam compressor. Background Art

[0002] A centrifugal steam compressor is a device that uses centrifugal force to compress gas. It is widely used in industrial production, medical equipment, automobile manufacturing, aerospace and other fields. The air intake baffle is an important component of the compressor. Its main function is to form an air intake chamber together with the cylinder to guide the gas to the inlet of the first-stage impeller.

[0003] When existing centrifugal steam compressors are working, in order to be able to adjust the size and direction of the air inlet according to actual needs and ensure that the airflow enters the air inlet chamber more smoothly, adjustable blades are usually installed. However, during the working process, the adjustable blades need to withstand the impact of high-pressure and high-speed airflow formed after the gas is compressed through high-speed rotation, which can easily cause damage to the adjustable blades and produce abnormal noises, thereby affecting the overall use. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the adjustable blades need to withstand the impact of high-pressure and high-speed airflow formed after the gas is compressed by high-speed rotation, which is easy to cause damage to the adjustable blades and produce abnormal noise, thereby affecting the overall use, and a centrifugal steam compressor intake baffle is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An air intake baffle of a centrifugal steam compressor comprises a baffle entity and a baffle inner cavity opened in the baffle entity, wherein fixed blades are arranged on the same axis near the end position in the baffle inner cavity, and an adjusting groove is arranged in a circular array in the baffle inner cavity, and adjustable blades are movably installed in the adjusting groove through a mounting rod, and the adjustable blades are equiaxially installed with the fixed blades; a torsion spring is arranged at the outer end of the mounting rod located at the baffle entity, and an adjusting component for driving the adjustable blades to rotate is arranged on the outer side of the baffle entity.

[0007] Preferably, the adjustment assembly includes a conical gear ring movably mounted on the outside of the partition entity and a transverse connecting rod hinged on one side of the conical gear ring; a driving conical tooth that matches and meshes with the teeth of the conical gear ring is installed on one side of the conical gear ring, and the other end of the driving conical tooth is connected to a driving motor through a connecting rod, and the transverse connecting rod is hinged with the mounting rod through a telescopic connecting rod.

[0008] Preferably, the torsion spring is arranged between the telescopic connecting rod and the mounting rod.

[0009] Preferably, the inner wall cross-section of the partition cavity is high in the middle and low on both sides.

[0010] Preferably, the fixed blades are installed in an inclined manner.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By arranging an equiaxially mounted fixed blade at the front end of the adjustable blade, and the fixed blade has an inclination, it can guide the airflow when the airflow enters, and can provide a layer of protection for the adjustable blade, avoiding the high-speed rotating airflow from having a strong impact on the adjustable blade and causing damage, and avoiding abnormal noise from the adjustable blade.

[0013] 2. By providing a conical gear ring, driving conical teeth, a transverse connecting rod and a telescopic connecting rod, the angle of the adjustable blades can be adjusted, thereby guiding the airflow to ensure that the airflow can enter the air intake chamber more smoothly. By providing a torsion spring between the telescopic connecting rod and the mounting rod, when the adjustable blades are impacted by the strong and high-pressure airflow rotating at high speed during the operation of the compressor, the impact force on the adjustable blades can prompt the adjustable blades to rotate, thereby avoiding the vertical effect between the adjustable blades and the high-pressure airflow. When the torsion spring drives the adjustable blades to rotate, the force of the high-pressure airflow can be absorbed, reducing the impact on the adjustable blades and protecting the adjustable blades. After the air pressure flows, the torsion spring drives the adjustable blades to reset and waits for the next round of high-pressure airflow, thereby forming a cyclic absorption effect, thereby avoiding damage and abnormal noise caused by the adjustable blades under impact.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Reference Figure 1-4 The centrifugal steam compressor air intake baffle comprises a baffle entity 1 and a baffle inner cavity 101 opened in the baffle entity 1, wherein fixed blades 11 are arranged on the same axis near the end position in the baffle inner cavity 101, and an adjusting groove 102 is arranged in a circular array in the baffle inner cavity 101, and an adjustable blade 12 is movably installed in the adjusting groove 102 through a mounting rod 121, and the adjustable blade 12 is equiaxially installed with the fixed blade 11; a torsion spring 2 is arranged at the outer end of the mounting rod 121 located in the baffle entity 1, and an adjusting component 3 for driving the adjustable blade 12 to rotate is arranged on the outer side of the baffle entity 1.

[0022] Furthermore, the adjustment component 3 includes a conical gear ring 31 movably mounted on the outside of the partition entity 1 and a transverse connecting rod 34 hinged on one side of the conical gear ring 31; a driving conical tooth 32 matching and meshing with the teeth of the conical gear ring 31 is installed on one side of the conical gear ring 31, and a driving motor 33 is installed on the other end of the driving conical tooth 32 through a connecting rod 331. The transverse connecting rod 34 is hinged with the mounting rod 121 through a telescopic connecting rod 35.

[0023] It should be noted that the torsion spring 2 is arranged between the telescopic connecting rod 35 and the mounting rod 121 .

[0024] It is worth noting that the inner wall section of the partition cavity 101 is high in the middle and low on both sides, which can optimize the distribution of airflow, improve the air intake effect and reduce the backflow phenomenon.

[0025] It is worth noting that the fixed blades 11 are installed at an angle, which can play a preliminary role in combing the incoming airflow. At this time, the airflow has an inclined angle and can enter more smoothly, and can withstand part of the impact force of the airflow.

[0026] Further benefits of adopting the above are:

[0027] The motor 33 drives the connecting rod 331 to drive the conical teeth 32 to rotate back and forth, and the conical gear ring 31 is driven to rotate under the action of tooth adaptation, and the multiple mounting rods 121 are driven to rotate under the action of the transverse connecting rod 34 and the telescopic connecting rod 35, so that the multiple adjustable blades 12 are driven to move back and forth synchronously to adjust the size of the air inlet, ensuring that the airflow can enter the air intake chamber more smoothly, and the inclined fixed blades 11 reduce the impact of the airflow on the adjustable blades 12. Under the action of the torsion spring 2, the adjustable blades 12 are driven to rotate, absorb the force of the high-pressure airflow, and protect the adjustable blades 12 to avoid damage and abnormal noise caused by the impact of the adjustable blades 12.

[0028] When the utility model is in use, during the use of the steam engine, the high-pressure airflow enters through the end of the partition entity 1. When passing through the fixed blades 11, the inclined fixed blades 11 can play a preliminary combing role on the incoming airflow. At this time, the airflow has an inclined angle and can enter more smoothly, and can withstand part of the impact force of the airflow, reducing the impact effect of the airflow on the adjustable blades 12. When the airflow enters the adjustable blades 12, since the fixed blades 11 and the adjustable blades 12 are on the same axis, their inclination angles are initially the same. At this time, the strong airflow forms a vertical angle with the adjustable blades 12. The impact force is the greatest, and the adjustable blades 12 are driven to rotate under the action of the torsion springs 2, and the force of the high-pressure airflow is absorbed, reducing the impact force on the adjustable blades 12. After the air pressure flows, the torsion springs 2 drive the adjustable blades 12 to reset, waiting for the next round of high-pressure airflow, forming a cyclic absorption effect.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
