Description

Technical Field

[0001] The utility model relates to the technical field of vaccine production, in particular to avian embryo culture equipment for vaccines. Background Art

[0002] Vaccines are made by attenuating and inactivating pathogens of diseases. They are autoimmune preparations used to prevent infectious diseases. Vaccines produce specific immunity in humans or animals and are the most economical and effective means of preventing and controlling infectious diseases. Most vaccines are produced using chicken embryo cells.

[0003] At present, common poultry vaccine workshops on the market use embryo eggs for virus culture, and all of them will be equipped with an incubation system. For example, a chicken embryo incubation and freezing dual-purpose mechanism suitable for poultry vaccine production, which is CN206890957U, mentions a kind of incubation system, which includes an incubation control box and a temperature and humidity controller, an alarm, a temperature-averaging fan and a lighting and heating device all connected to the incubation control box signal. The temperature-averaging fan side is mounted on the side wall near the egg-entry end of the incubator to promote the air in the incubator to flow along the inner side of the incubator. However, due to the fixed position of the temperature-averaging fan, the blowing direction and relative position of the airflow cannot be adjusted for vaccine egg carts of different sizes, which affects the heat-averaging effect of the poultry embryo. In addition, since the existing incubators are all rectangular internal spaces, the circulating wind at their top and bottom edges is easily affected by the obstruction of the space corners, which affects the smooth flow of the circulating wind and thus affects the heat-averaging effect of the poultry embryo, thereby reducing production efficiency.

DETAILED DESCRIPTION

[0024] In order to make the present invention more clear, the present invention is further described below in conjunction with the accompanying drawings. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] like Figure 1 , Figure 2 As shown, a poultry embryo culture device for vaccine includes a culture chamber 1. The culture chamber 1 is in a three-dimensional rectangular shape as a whole. It is formed by welding a bottom plate 11, two side vertical plates 12, two end plates 13 and a top plate 14. The two end plates 13 are located at the two ends of the length direction of the culture chamber 1. Two door openings are respectively provided on the two end plates 13. The door openings are equipped with a door body 2 that can be opened and closed. The door body 2 is arranged in a double-leaf form. A three-dimensional rectangular culture space 3 is formed inside the culture chamber 1. A pair of parking spaces for placing vaccine egg carts 100 are symmetrically provided in the culture space 3. The vaccine egg cart 100 is preferably an egg cart structure with three partitions. The two parking spaces are linearly arranged along the length direction of the culture chamber 1, and there is a space for air flow between the two parking spaces. An air supply device 4 is respectively provided above the adjacent areas of the two parking spaces. Each air supply device 4 forms the space where the corresponding vaccine egg cart 100 is located as shown in the figure. Figure 2 Annular circulating airflow shown.

[0026] Combination Figure 1 , Figure 3As shown, each air supply device 4 includes a rotating rod 41 and a swing rod 42 arranged in parallel, and a group of fans 43. The fan 43 is an axial flow fan, and through holes 431 corresponding to the rotating rod 41 and the swing rod 42 are respectively provided on the upper and lower sides of its rectangular shell. The fan 43 is respectively damped and penetrates the rotating rod 41 and the swing rod 42 through the through holes 431, and the group of fans 43 is arranged horizontally, and each fan 43 can move along the length direction of the rotating rod 41 and the swing rod 42 to adjust the relative position of each fan 43, and then adjust the relative position of the airflow. Since the fan 43 has a certain damping effect when moving on the rotating rod 41 and the swing rod 42, it can be ensured that the fan 43 will not move relatively during operation and can remain stable. The rotating rod 41 is rotatably connected to the two side vertical plates 12 of the culture chamber 1 through the seat bearing, and the seat bearing can be located on the inner side or outer side of the vertical plate 12; the two side vertical plates 12 are provided with an arc waist hole 121 set with the seat bearing as the center of the circle, and the end of the swing rod 42 is inserted into the arc waist hole 121 corresponding to the gap and extends a certain length, and the swing rod 42 can swing along the arc waist hole 121. A locking device 5 is connected to the extended part, and the locking device 5 can lock the relative position of the swing rod 42 in the arc waist hole 121, thereby changing and fixing the swing angle of the group of fans 43, thereby adjusting the flow direction of the airflow. In this embodiment, the locking device 5 is a locking nut 51, and correspondingly, the extended part of the swing rod 42 is provided with an external thread 421. When the locking nut 51 cooperates with the external thread 421, the inner end face of the locking nut 51 is pressed and locked on the outer surface of the vertical plate 12, thereby realizing the adjustable fixation of the swing rod 42. Of course, the locking device 5 can also be some other conventional locking structures.

[0027] A temperature and humidity sensor 6 and a heating device 7 are also provided in the culture chamber 1. The fan 43, the temperature and humidity sensor 6 and the heating device 7 are electrically connected to the controller (not shown in the figure). The temperature and humidity sensor 6 can be arranged at multiple points in the culture chamber 1, which are only schematically indicated in the figure; the heating device 7 generates heat to heat the air, and the fan 43 tilts the hot air upward and toward the same side area to form a circulating hot air flow to evenly act on the avian embryos in the vaccine egg cart. The temperature and humidity conditions in the culture chamber 1 are monitored by the temperature and humidity sensor 6, and the corresponding signal is transmitted to the controller, and the controller controls the fan 43 and the heating device 7 to adjust the temperature and humidity of the culture chamber 1. Among them, the heating device 7 can use a heat light source that can be illuminated, and it is preferred to evenly arrange the heat light source on the inner wall of the top plate 14.

[0028] In order to facilitate the entry, exit and movement of the vaccine egg cart 100, a pair of rails 15 are arranged in parallel along the length direction on the inner wall of the bottom plate 11 of the culture chamber 1, and the vaccine egg cart 100 is provided with corresponding rollers 101. In addition, a heat insulation layer, such as a rock wool board, is also provided on the outer wall of the culture chamber 1 and the outer wall of the door body 2 to reduce the influence of the external environment on the temperature in the culture space.

[0029] In some embodiments, in order to improve the smoothness of the circulating airflow and reduce the obstruction of the edge dead corner of the culture space 3, the Figure 1 As shown, a first air guide device 8 is provided at the upper part of the culture space 3 near the door body 2. The first air guide device 8 includes a first rod 81, which is rotatably connected to the two vertical plates 12 through a bearing, and a group of wind wheels 82 are fixedly connected to the first rod 81 and are arranged equidistantly along the axial direction thereof. The wind wheel 82 has a group of straight blades evenly distributed along the radial circumference thereof, and the straight blades are plate-like structures, and the force-bearing surfaces of the blades are arranged parallel to the axial direction of the wind wheel 82. Further, a second air guide device 9 is provided at the lower area on the inner side of the door body 2, and the second air guide device 9 includes a pair of bearing seats 91 fixed to the inner side of the door body 2, and the two bearing seats 91 are coaxially rotatably connected to the second rod 92, and the wind wheel 82 with a group of straight blades is connected to the second rod 92. When the circulating airflow passes through the first air guide device 8, the airflow direction is changed under the action of the straight blades, and the airflow is smoothly changed from horizontal to vertical downward. When passing through the second air guide device 9, the airflow is changed from vertical to horizontal. In this process, the first and second air guide devices play a role in reversing and guiding, reducing the adverse effects of the dead corners of the culture space 3. Preferably, the wind wheel 82 is a powered wind wheel. It should be noted that the active rotation direction of the wind wheel 82 should be along the flow direction of the circulating airflow. Of course, in some use environments with lower requirements, the wind wheel 82 can also be a non-powered wind wheel.

[0030] When the device is in use, a symmetrically arranged parking space structure for vaccine egg carts is adopted. Compared with traditional vaccine incubators, the internal flow field of the vaccine incubator is greatly optimized, the temperature gradient is improved, and the uniformity of avian embryo development is greatly improved. The blowing direction of the circulating airflow can also be adjusted according to vaccine egg carts of different sizes. In addition, the first and second air guide devices are provided to reduce the obstruction of the top wall and the bottom edge of the culture space, thereby improving the heat uniformity effect of the avian embryo and the vaccine preparation efficiency.

[0031] The above embodiments of the utility model are merely examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the utility model still belong to the protection scope of the utility model.
