Description

Technical Field

[0001] The invention relates to the technical field of sterile product processing and production equipment, and in particular to a sterile product recovery device. Background Art

[0002] CIP cleaning system is commonly known as in-place cleaning system. It is widely used in beverage, dairy, juice, pulp, jam, wine and other food and beverage production enterprises with high degree of mechanization. In-place cleaning means that the equipment is not disassembled or moved, that is, high temperature and high concentration cleaning liquid is used to strongly act on the equipment to clean the contact surface with food. It is used for cleaning and purification of production equipment with strict hygiene requirements.

[0003] SIP online sterilization system usually uses saturated steam to effectively kill microorganisms and spores in a short time. It is used for production equipment with more stringent requirements.

[0004] However, the production equipment starts production after CIP / SIP, and then maintains a sanitary or aseptic production environment. After the production is completed, there are often residual products in the pipeline. Based on the principle of economy, the products need to be recovered in a sanitary or aseptic environment before the equipment CIP / SIP is performed. In the prior art, a method of using piglets to push residual liquid materials in the product pipeline, especially liquid materials with high viscosity that are easily attached to the pipeline, to achieve the purpose of product recovery has been widely used.

[0005] In the prior art, the piglets are in the pig cage of the departure station. The departure station contains two cylinders that can push or block the piglets. The cylinders are used to push the pig heads into the product pipeline or block them in the pig cage of the departure station through the extension and retraction of the valve stems. The lateral cylinder pushes out, and the piglets are locked in the pig cage by the lateral cylinder, and the longitudinal cylinder retracts; the lateral cylinder retracts to make the piglets' exit unobstructed, and the longitudinal cylinder extends to push the piglets out of the pig cage. During the extension and retraction of the cylinder valve stem, part of the valve stem is outside the pig cage, so it contacts the environment outside the pig cage, and the inside of the pig cage may contact external unclean pollution, thereby destroying the hygienic or sterile environment inside the pig cage. At the same time, the method of using cylinders to push and block piglets increases the overall volume of the departure station, and the large space occupied hinders the installation of other equipment, resulting in usage limitations.

[0006] Therefore, how to change the current situation in which the hygiene or sterile environment inside the pig cage is destroyed by pushing and blocking the piglets through the cylinder has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0023] The purpose of the present invention is to provide a sterile product recovery device to solve the problems existing in the above-mentioned prior art, avoid external contamination of the interior of the product production equipment, and improve the safety of product recovery.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figure 1-3 ,in, Figure 1 is a schematic diagram of the overall structure of the sterile product recovery device of the present invention, Figure 2 is a schematic cross-sectional view of the structure of the sterile product recovery device of the present invention, Figure 3 It is a schematic side view of the structure of the sterile product recovery device of the present invention.

[0026] The present invention provides a sterile product recovery device, comprising a starting station 1, a piglet 2, a pig cage 3, a paddle 4, a first driver 5 and a second driver 6, wherein the piglet 2, the pig cage 3 and the paddle 4 are all arranged in a cavity of the starting station 1, the starting station 1 has an inlet 9 and an outlet 10, the inner cavity of the starting station 1 is connected with a product pipeline through the inlet 9 and the outlet 10, the pig cage 3 is connected to the first driver 5 by transmission, the first driver 5 can drive the pig cage 3 to rotate, the piglet 2 can be accommodated in the pig cage 3 and the pig cage 3 can drive the piglet 2 to rotate, the paddle 4 is connected to the second driver 6 by transmission, the second driver 6 can drive the paddle 4 to rotate, the pig cage 3 The rotating axis of the pig cage 3 and the paddle 4 is parallel to the axis of the outlet 10 and the inlet 9. The paddle 4 is located on the side of the departure station 1 close to the inlet 9. The pig cage 3 has an opening that allows the piglet 2 to enter and exit. The opening of the pig cage 3 can face the outlet 10. The pig cage 3 also has a socket. When the paddle 4 rotates, it can enter the pig cage 3 through the socket. The piglet 2 is made of rubber material. A magnet is arranged in the piglet 2. The specification of the piglet 2 is compatible with the inner diameter of the product pipeline. The piglet 2 can enter and exit the inner cavity of the departure station 1 through the outlet 10. The piglet 2 can move in the product pipeline. The pig cage 3 is made of stainless steel. It should be emphasized here that because the device is suitable for sterile products or sanitary products, the piglet 2 and the pig cage 3 are both CIP / SIP treated to ensure compliance with hygiene standards.

[0027] When the departure station 1 is in a closed state, the piglet 2 is located in the pig cage 3, and the axis of the pig cage 3 is perpendicular to the axis of the outlet 10. During operation, the first driver 5 drives the pig cage 3 and the piglet 2 to rotate 90°, and the openings of the piglet 2 and the pig cage 3 face the outlet 10. After the first driver 5 stops, the second driver 6 drives the paddle 4 to rotate, and the paddle 4 extends into the pig cage 3 from the socket and pushes the piglet 2. When the piglet 2 enters the product pipeline from the outlet 10, the second driver 6 stops, and the piglet 2 moves in the product pipeline to recover the product remaining in the pipeline. The second driver 6 drives the paddle 4 to reset, and the piglet 2 will reach the product recovery point and move in the opposite direction and finally return to the departure station 1 and enter the pig cage 3. The first driver 5 drives the piglet 2 and the pig cage 3 to rotate and return to the initial position, and the recovery process is completed. During the operation of the device, the sterilized parts have no contact with the external environment, which effectively prevents the sterile environment in the production equipment from being contaminated by the outside, and improves the hygiene level of the device. At the same time, the piglet 2 is pushed into the product pipeline in a rotating manner, which reduces the overall volume of the device and does not limit the installation direction, thereby improving the applicability of the device. It should be noted that the piglet 2 can be provided with a magnet to facilitate the system to detect the position of the piglet 2. The pig cage 3 is made of stainless steel, which is suitable for the CIP / SIP environment and will not interfere with the magnet in the piglet 2.

[0028] Among them, the first driver 5 is connected to the first rotating shaft 7, the pig cage 3 is connected to the first rotating shaft 7, the second driver 6 is connected to the second rotating shaft 8, the paddle 4 is arranged on the second rotating shaft 8, the first rotating shaft 7 and the second rotating shaft 8 are arranged in parallel, the axis of the outlet 10 and the axis of the inlet 9 are both perpendicular to the axis of the first rotating shaft 7, and the distance between the pig cage 3 and the second rotating shaft 8 is less than the length of the paddle 4 protruding from the second rotating shaft 8, ensuring that the paddle 4 can smoothly push the piglet 2 in the pig cage 3.

[0029] In this specific embodiment, the piglet 2 includes a connected truncated cone portion and a spherical portion. The bottom diameter of the truncated cone portion is consistent with the diameter of the product pipeline, and the diameter of the spherical portion is not greater than the diameter of the product pipeline. When the piglet 2 enters the product pipeline, the truncated cone portion faces the forward direction, and the end of the truncated cone portion with a smaller diameter is connected to the spherical portion. The end of the truncated cone portion with a larger diameter can scrape and recycle the residual product in the product pipeline. When the piglet 2 moves back to the starting station 1 in the reverse direction, the spherical portion faces the forward direction to reduce the movement resistance.

[0030] Specifically, one end of the spherical portion away from the truncated cone portion has a flat surface, which increases the contact area between the paddle 4 and the spherical portion, so that the paddle 4 can smoothly push the piglet 2 .

[0031] In order to reduce the friction resistance between the paddle 4 and the piglet 2 , the end of the paddle 4 away from the second rotating shaft 8 has a curved surface.

[0032] More specifically, a transition connection portion is provided between the truncated cone portion and the spherical portion, and the transition connection portion is chamfered to avoid material residue. When the piglet 2 is located in the pig cage 3, in order to prevent the piglet 2 from slipping out of the pig cage 3 and being dislocated, the pig cage 3 is provided with a clamping head, and the piglet 2 is clamped with the pig cage 3. In this specific embodiment, the clamping head clamps the transition connection portion. In other specific embodiments of the present invention, the clamping head can also be clamped with other parts of the piglet 2. When the paddle 4 applies force to the piglet 2, the piglet 2 is pushed to move after overcoming the force of the clamping head, thereby avoiding the dislocation of the piglet 2. At the same time, the stability of the device is enhanced, the restrictions of the device on the installation orientation are reduced, and the applicability of the device is improved.

[0033] Furthermore, the pig cage 3 is fixedly connected to the first rotating shaft 7 to avoid sanitary dead corners and improve operational convenience.

[0034] In addition, the distance between the axis of the inlet 9 and the axis of the outlet 10 is equal to the distance between the axis of the pig cage 3 and the axis of the outlet 10. The inlet 9 and the pig cage 3 are located at the same height, which is convenient for the piglet 2 to enter and exit. The distance between the axis of the inlet 9 and the axis of the outlet 10 is not equal to zero, that is, the inlet 9 and the outlet 10 are not at the same height, avoiding the impact of materials entering and exiting on the parts in the starting station 1.

[0035] The sterile product recovery device of the present invention is that when the departure station 1 is in a closed state, the piglet 2 is located in the pig cage 3, and the axis of the pig cage 3 is perpendicular to the axis of the outlet 10. When working, the first driver 5 drives the pig cage 3 and the piglet 2 to rotate 90°, and the openings of the piglet 2 and the pig cage 3 are directly opposite to the outlet 10. After the first driver 5 stops, the second driver 6 drives the paddle 4 to rotate, and the paddle 4 extends into the pig cage 3 from the socket and pushes the piglet 2. When the piglet 2 enters the product pipeline from the outlet 10, the second driver 6 stops, and the piglet 2 moves along the product pipeline under the action of the propellant to recover the product remaining in the pipeline. The second driver 6 drives the paddle 4 to reset, and the piglet 2 will reach the product recovery point and move in the opposite direction and finally return to the departure station 1 and enter the pig cage 3. The first driver 5 drives the piglet 2 and the pig cage 3 to rotate and return to the initial position. The recovery process is completed, thereby locking the piglet 2 in the pig cage 3.

[0036] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
