Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1:

[0032] Reference Figure 1 , Figure 4 and Figure 5The utility model provides an embodiment: a dryer for freeze-dried powder injection production, including a freeze dryer 1, a sealed door 4 is arranged on the front side of the freeze dryer 1, hinges 3 are fixedly connected to the left and right sides of the outer wall of the sealed door 4, the sealed door 4 is rotatably connected to the freeze dryer 1 through the hinges 3, the left and right sides of the inner wall of the freeze dryer 1 are rotatably connected to rotating blocks 5, a cross plate 6 is fixedly connected to the outer side of the rotating block 5, a plurality of material storage troughs 7 are rotatably connected between the rotating block 5 and the cross plate 6, a counterweight rod 8 is fixedly connected to the bottom of the material storage trough 7, and a counterweight rod 8 is arranged at the bottom of the front counterweight rod 8.

[0033] Specifically, through the elastic potential energy of the torsion spring 27, the cross plate 6 and the material storage tank 7 thereon can be driven to rotate continuously through the rotating block 5, and the rotation direction is counterclockwise when viewed from the left side. When the material storage tank 7 rotates, it can be kept vertical by the counterweight rod 8 at the bottom, and the counterweight rod 8 located on the front side is engaged with the fixed hook 12. At this time, the freeze-dried material to be placed in the material storage tank 7, as the weight of the material storage tank 7 increases, the counterweight rod 8 will press the fixed hook 12, so that the fixed hook 12 rotates along the inner side of the freeze dryer 1 through the rotating rod 11 thereon, and at the same time compresses the spring 10, at this time, as the fixed hook 12 rotates, the inner side will be The counterweight rod 8 loses its fixation, and at the same time, the elastic potential energy of the torsion spring 27 will drive the cross plate 6 to continue to rotate. At this time, the full storage tank 7 will be moved away, and the storage tank 7 with stored materials on the upper side and the counterweight rod 8 will automatically rotate to engage with the fixed hook 12, so that the device can quickly store and retrieve materials. When all the storage tanks 7 are full, the weight difference is not large and the elastic potential energy of the torsion spring 27 has rotated to the extreme position, making its potential energy tend to rotate clockwise. Therefore, the problem of the fixed hook 12 losing its fixing effect on the counterweight rod 8 after all the storage tanks 7 are full will not occur. The freeze dryer 1 can use the YTLG-10A vacuum freeze dryer. Embodiment 2:

[0034] Reference Figure 2 and Figure 4The cleaning mechanism 2 includes a reserved groove 201, which is provided at the inner bottom of the freeze dryer 1. A heater 202 is fixedly connected to the rear side of the freeze dryer 1. The output end of the heater 202 passes through the freeze dryer 1 and is fixedly connected to a heating wire 203. Filter grooves 208 are provided on the left and right sides of the bottom of the inner wall of the freeze dryer 1. The filter groove 208 is connected to the reserved groove 201. A scraper 207 is slidably connected to the inner side of the filter groove 208. A positioning rope 205 is fixedly connected to the outer side of the filter groove 208. Positioning wheels 206 are rotatably connected to the left and right sides of the bottom of the inner wall of the freeze dryer 1. The positioning wheel 206 is transmission-connected to the filter groove 208 through the positioning rope 205. U-shaped blocks 204 are fixedly connected to the left and right sides of the bottom of the outer wall of the sealing door 4. The other end of the positioning rope 205 is fixedly connected to the U-shaped block 204.

[0035] Specifically, by filling the reserved groove 201 with cleaning liquid or clean water, the heater 202 is started to heat the heating wire 203, and the clean water in the reserved groove 201 is evaporated. The steam will be discharged through the filter groove 208, and the inside of the freeze dryer 1 will be sterilized by its high-temperature steam. At the same time, as the steam condenses on the top of the inner wall of the freeze dryer 1, the condensed water will move down along its inner wall, clean the internal structure of the freeze dryer 1 and its own inner wall, and then flow back into the reserved groove 201 through the filter groove 208. After being filtered by the filter groove 208, the impurities therein will be intercepted on the top surface of the filter groove 208. At this time, the sealing door 4 is opened, and the scraper 207 is pulled to scrape along the filter groove 208 through the transmission of the positioning rope 205 and the positioning wheel 206 on the U-shaped block 204, so as to facilitate the collection and cleaning of impurities on its surface. Embodiment three:

[0036] Reference Figure 1 , Figure 3 and Figure 5 , a first gear 13 is fixedly connected to the outer side of the rotating rod 11, and the outer side of the first gear 13 is rotatably connected to the freeze dryer 1. A second gear 14 is arranged on the front side of the first gear 13, and the second gear 14 is rotatably connected to the freeze dryer 1. A limit plate 15 is fixedly connected to the outer side of the second gear 14, and the limit plate 15 is engaged with the cross plate 6; positioning blocks 21 are fixedly connected to the bottom of the outer wall of the freeze dryer 1, and positioning holes 22 are provided on the outer side of the positioning blocks 21; a controller 23 is fixedly connected to the left side of the freeze dryer 1, and the controller 23 is electrically connected to the freeze dryer 1 and the heater 202 respectively;

[0037] Specifically, the rotation of the rotating rod 11 can simultaneously drive the first gear 13 to rotate, so as to drive the second gear 14 and its upper limit plate 15 to rotate through meshing transmission. Since the limit plate 15 is engaged with the cross plate 6 to limit its rotation, when the weight of the storage trough 7 is high and drives the fixed hook 12 and the rotating rod 11 to rotate, the engagement between the limit plate 15 and the cross plate 6 can be disengaged. When the fixed hook 12 and the counterweight rod 8 are fixed, the limit plate 15 can be engaged with the cross plate 6 to enhance the firmness of the fixation to the cross plate 6. By installing a threaded part in the positioning hole 22 on the positioning block 21, the device can be easily installed and fixed. The start-up and operating power of the freeze dryer 1 and the heater 202 can be controlled respectively by the controller 23, wherein the controller 23 can use a TC55V motion controller.

[0038] Reference Figure 2 , Figure 3 and Figure 5 A slide groove 19 is provided on the front side of the inner wall of the freeze dryer 1, a sealing cover 18 is slidably connected to the inner side of the slide groove 19, and a water injection port 20 is connected to the front side of the sealing cover 18; a handle 24 is fixedly connected to the middle of the front end of the sealing door 4, and a sheath 25 is fixedly connected to the outer side of the handle 24; a connecting plate 17 is fixedly connected to the bottom of the mounting block 9, a bracket 16 is fixedly connected to the bottom of the connecting plate 17, and the outer side of the bracket 16 is fixedly connected to the freeze dryer 1;

[0039] Specifically, water can be easily injected into the reserved groove 201 through the water filling port 20, and the water in the reserved groove 201 can be discharged by opening the sealing cover 18 along the slide groove 19, and the inside thereof can be cleaned to prevent the breeding of bacteria. The handle 24 can facilitate the opening and closing of the sealing door 4, and the protective cover 25 thereon can improve the comfort of holding. The fixation of the bracket 16 and the connecting plate 17 thereon can improve the firmness of the fixation between the mounting block 9 and the freeze dryer 1.

[0040] Working principle: Before using the device, first, through the elastic potential energy of the torsion spring 27, the rotating block 5 can drive the cross plate 6 and the storage tank 7 thereon to rotate continuously. If viewed from the left side, its rotation direction is counterclockwise. During the rotation process, the counterweight rod 8 at the bottom of the storage tank 7 can keep it vertical during rotation. The counterweight rod 8 located at the front side will engage with the fixed hook 12. At this time, the material to be freeze-dried can be placed in the storage tank 7. As the weight of the material in the storage tank 7 increases, it will be moved to the storage tank 7 through the counterweight rod 8. The fixed hook 12 applies pressure, causing the fixed hook 12 to rotate along the inner side of the freeze dryer 1 by means of the rotating rod 11 thereon, and compressing the spring 10 at the same time. At this time, as the fixed hook 12 rotates, the counterweight rod 8 inside it loses its fixation, and due to the elastic potential energy of the torsion spring 27, the cross plate 6 will continue to rotate. At this time, the full storage tank 7 will be moved away, and the storage tank 7 and the counterweight rod 8 on the upper side for storing materials will automatically rotate and engage with the fixed hook 12, so that the material storage and retrieval operation of the device can be quickly realized;

[0041] By filling the reserved groove 201 with cleaning liquid or clean water, and then starting the heater 202 to heat the heating wire 203, the clean water in the reserved groove 201 is evaporated, and the steam generated by evaporation will be discharged through the filter groove 208, and its high-temperature steam will be used to sterilize the inside of the freeze dryer 1. At the same time, after the steam condenses at the top of the inner wall of the freeze dryer 1, the condensed water will move downward along the inner wall to clean the internal structure of the freeze dryer 1 and the inner wall itself, and then flow back to the reserved groove 201 through the filter groove 208. With the help of the filtering effect of the filter groove 208, the impurities therein will be blocked on the top surface of the filter groove 208. At this time, the sealing door 4 is opened, and the positioning rope 205 on the U-shaped block 204 and the positioning wheel 206 are driven to pull the scraper 207 to scrape along the filter groove 208, so as to collect and clean the impurities on the surface of the filter groove 208.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
