Description

Technical Field

[0001] The utility model relates to the technical field of sterilizers, in particular to a steam jet sterilizer. Background Art

[0002] Steam jet sterilizer is a device that uses high-temperature steam for sterilization. It is widely used in medical, food processing, laboratory and other fields. Its working principle is mainly to generate steam by heating water, and then spray the high-temperature steam onto the surface of the object to be sterilized, quickly killing bacteria, viruses and other microorganisms.

[0003] After searching, the Chinese patent publication number CN205180244U discloses a steam jet sterilizer, including a sterilizer body and a material conveyor and at least two steam injection devices respectively arranged on the sterilizer body. The sterilizer body is a hollow cylinder with a material cavity in the middle. The end of the material conveyor and the end of the steam injection device are both connected to the material cavity. A material inlet and a steam inlet are provided on the sterilizer body. The material inlet and the steam inlet are both tangent to the inner wall of the sterilizer body. The outer ends of the material inlet and the steam inlet are respectively connected to the material conveyor end and the lower end of the steam injection device, and the inner ends of the material inlet and the steam inlet are connected to the material cavity. The steam injection devices correspond to their respective steam inlets, and a discharge port is provided at the end of the sterilizer body.

[0004] The above patent has the following deficiencies: by setting the material inlet and the steam inlet in a direction tangent to the inner wall of the sterilizer body, the liquid material and steam are sprayed into the material cavity in a direction tangent to the inner wall of the sterilizer body under the pressure of the steam injection device and rotated at high speed, which helps to mix the liquid material and steam. However, when the liquid material and steam enter the inner wall of the sterilizer body in the same direction, the mixing effect is poor. When the liquid material and steam enter the inner wall of the sterilizer body in opposite directions, the collision of the two materials will cause kinetic energy loss of the material conveying equipment.

[0005] Therefore, a steam jet sterilizer is proposed. Utility Model Content

[0026] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-3 As shown, a steam jet sterilizer includes a sterilizer body 3 and a nozzle 1 movably connected to the output end of the sterilizer body 3 through a swing component 2.

[0031] The inner wall of the sterilizer body 3 on one side away from the nozzle 1 is fixedly connected and communicated with a delivery pipe 1 4 and a delivery pipe 2 5. The delivery pipe 1 4 and the delivery pipe 2 5 are arranged symmetrically and tilted to each other, and the other ends of the delivery pipe 1 4 and the delivery pipe 2 5 are respectively connected to a pump 1 and a pump 2. The inner wall of the sterilizer body 3 is fixedly connected with a plurality of spiral blades 1 6 and spiral blades 2 7 arranged at intervals, and the spiral directions of the spiral blades 1 6 and the spiral blades 2 7 are opposite.

[0032] Pump 1 and pump 2 respectively deliver steam and liquid materials into the nozzle 1. Since the delivery pipe 1 4 and the delivery pipe 2 5 are both arranged at an angle, the collision between the steam and liquid materials is an inclined collision, so that only the momentum is lost along the collision direction, thereby reducing the kinetic energy loss of the fluid. Since the spiral blade 1 6 and the spiral blade 2 7 are arranged at intervals and in opposite spiral directions, the moving direction of the steam and liquid materials can be alternately changed, and they move toward the nozzle 1 in an alternating counterclockwise and clockwise rotation, which is conducive to the mixing of the steam and liquid materials.

[0033] By providing the delivery pipe 1 4 and the delivery pipe 2 5 and arranging the delivery pipe 1 4 and the delivery pipe 2 5 at an angle, the collision between the steam and the liquid material can be converted into an inclined collision, so that only the momentum is lost in the collision direction, reducing the kinetic energy loss of the fluid. With the assistance of the spiral blade 1 6 and the spiral blade 2 7, the steam and liquid materials can be mixed, so that the mixing effect is not affected by the direction in which the steam and liquid materials enter the inner wall of the nozzle 1, thereby ensuring the mixing of the materials and the sterilization effect.

[0034] In this embodiment, the inner wall of the sterilizer body 3 is fixedly connected to and communicates with the shell 8, and the inner wall of the shell 8 is rotatably connected to a plurality of radially arranged fan blades 10 via an axis 9.

[0035] When the steam and liquid material mixture flows through the shell 8, it drives the fan blades 10 to rotate, and the rotation of the fan blades 10 can further improve the mixing uniformity of the mixture.

[0036] Example 2:

[0037] A steam jet sterilizer, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-3 As shown:

[0038] The swing assembly 2 includes a bellows 11 and a second connecting rod 15. The bellows 11 is fixedly connected to the nozzle 1 and the opposite side of the sterilizer body 3, and the nozzle 1, the bellows 11 and the inner cavity of the sterilizer body 3 are interconnected.

[0039] By utilizing the retractable property of the bellows 11 , the nozzle 1 can swing back and forth, thereby increasing the spray range and improving the uniformity of the spray.

[0040] The outer wall of the nozzle 1 is fixedly connected to the second shaft 12, one end of the second connecting rod 15 is rotatably connected to the second shaft 12, and the other end of the second connecting rod 15 is fixedly connected to the outer wall of the sterilizer body 3.

[0041] The outer wall of the second shaft 12 is fixedly connected to the first connecting rod 13, and the other end of the first connecting rod 13 is rotatably connected to the third connecting rod 16 through the third shaft 14.

[0042] One end of the shaft 1 9 passes through the housing 8 and is fixedly connected to a turntable 18 . A shaft 4 17 is eccentrically provided on the outer wall of the turntable 18 . The other end of the connecting rod 3 16 is rotatably connected to the shaft 4 17 .

[0043] When the mixture of steam and liquid material passes through the fan blade 10 at high speed, it hits the surface of the fan blade 10 to make it rotate, and the fan blade 10 drives the shaft 9 to rotate, so that the turntable 18 rotates with the shaft 9. Under the transmission cooperation of the connecting rod 3 16, the connecting rod 2 15 and the connecting rod 1 13, the nozzle 1 swings back and forth along the axis of the shaft 2 12 as the rotation center.

[0044] By providing the swing assembly 2, the nozzle 1 can swing back and forth, thereby realizing swing-type spraying, which can not only increase the spray range but also improve the uniformity of the spray, thereby improving the efficiency while ensuring the sterilization effect.

[0045] Working principle: When in use, start pump 1 and pump 2 to deliver steam and liquid materials to the nozzle 1 respectively. Since the delivery pipe 1 4 and the delivery pipe 2 5 are both arranged at an angle, the collision between the steam and liquid materials is an inclined collision, so that only the momentum loss is along the collision direction, thereby reducing the kinetic energy loss of the fluid. Since the spiral blade 1 6 and the spiral blade 2 7 are arranged at intervals and the spiral directions are opposite, they can alternately change the moving direction of the steam and liquid materials, and move them toward the nozzle 1 in an alternating counterclockwise and clockwise rotation, which is conducive to the steam and liquid materials. After preliminary mixing, when the mixture passes through the fan blade 10 at high speed, the surface of the fan blade 10 is slapped to make it rotate, so as to achieve re-mixing of the mixture and ensure the uniformity of the mixing. The fan blade 10 can drive the shaft 9 to rotate, so that the turntable 18 rotates with the shaft 9. Under the transmission cooperation of the connecting rod three 16, the connecting rod two 15 and the connecting rod one 13, the nozzle 1 swings back and forth along the axis of the shaft two 12 as the rotation center, realizing swinging spraying, which can not only increase the spray range but also improve the uniformity of the spray, thereby improving the efficiency and ensuring the sterilization effect.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
