DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] For example, see Figure 1-3 , the present invention provides a technical solution: a heat recovery device for a refrigeration system of an artificial climate chamber, comprising a refrigeration device 1, an outer wall of the refrigeration device 1 is provided with a discharge port 2, and a guide mechanism 3 is fixedly connected to the outer wall of the refrigeration device 1; Combined with Figure 1 As shown, when the refrigeration device 1 is in operation, the hot gas generated inside enters the guide bin 33 through the discharge port 2 under pressure, and the guide bin 33 plays a role in initially converging and guiding the airflow, so that the gas can smoothly enter the elbow 341; Guide mechanism 3: An impurity box 32, the impurity box 32 is fixedly connected to the outer wall of the refrigeration device 1; A guide bin 33, the guide bin 33 is fixedly connected to the outer wall of the impurity box 32; The motor 35 is also fixedly connected to the outer wall of the refrigeration device 1; The processing assembly 34 and the outer wall of the motor 35 are rotatably connected to the processing assembly 34 .

[0024] The impurity box 32 is fixedly connected to the outer wall of the refrigeration device 1 through the bracket 31, and the motor 35 is fixedly connected to the outer wall of the guide bin 33; During the process of discharging the airflow from the outlet 2, the impact force of the airflow discharged from the outlet 2 is utilized. After the motor 35 is started, its output shaft drives the connecting rod 346 to make a circular motion, thereby causing the impact rod 347 to rotate around the outer wall of the motor 35. When the impact rod 347 rotates to a position in contact with the blocking block 343, the impact force of the impact rod 347 overcomes the elastic force of the spring 342, forcing the blocking block 343 to move outward along the outer wall of the curved pipe 341, thereby opening the discharge hole 345. At this time, the gas in the curved pipe 341 is quickly discharged from the discharge hole 345 driven by the impact force of the airflow discharged from the outlet 2. When the impact rod 347 continues to rotate and leave the blocking block 343, the elastic force generated by the spring 342 recovers the deformation to pull the blocking block 343 back to the initial position, and close the discharge hole 345 again. This cycle is repeated, and the motor 35 continues to operate stably, so that the gas can be discharged from the curved pipe 341 in a periodic pulsed manner.

[0025] The guide chamber 33 is located at the position of the discharge port 2 , and the guide chamber 33 is communicated with the interior of the impurity box 32 .

[0026] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The processing assembly 34 includes a curved pipe 341, which is rotatably connected to the outer wall of the guide bin 33, and the outer wall of the curved pipe 341 is provided with a discharge hole 345, and the outer wall of the curved pipe 341 is elastically fixedly connected to a blocking block 343, and the outer wall of the motor 35 is rotatably connected to a striking rod 347; During the flow of gas in the curved pipe 341, due to the non-contact between the curved pipe 341 and the guide bin 33, a detailed analysis is performed in combination with the Bernoulli principle. When the gas flows in the curved pipe 341, at the curved portion and where the discharge hole 345 is located, because the air flow difference between the discharge hole 345 at the curved portion of the curved pipe 341 and the end of the curved pipe 341 is different, the pressure difference is different, and then the impurities are squeezed under pressure and discharged from the discharge hole 345 into the impurity box 32.

[0027] A spring 342 is fixedly connected between the curved pipe 341 and the shielding block 343 , a hole is opened on the outer wall of the impurity box 32 at the position of the curved pipe 341 and the motor 35 , and a bearing 344 is rotatably connected between the curved pipe 341 and the guide bin 33 .

[0028] The blocking block 343 is located at the position of the discharge hole 345 , and the motor 35 is rotatably connected to the impact rod 347 via the connecting rod 346 .

[0029] The impact rod 347 is in active contact with the shielding block 343 , and the shielding block 343 is provided with a groove adapted to the shape of the impact rod 347 .

[0030] The bottom of the impurity box 32 is rotatably connected with a door panel 6; According to the Bernoulli equation, the pressure is low where the flow rate is high, and the pressure is high where the flow rate is low. Therefore, a pressure area is formed at the outlet hole 345 of the elbow 341, which is smaller than the end of the elbow 341. This pressure difference produces many positive effects. On the one hand, for the airflow itself, the pressure difference makes the gas more inclined to flow out from the outlet hole 345, ensuring that the gas can be discharged smoothly according to the designed path, avoiding turbulence or retention inside the elbow 341, and maintaining the stable transmission of the airflow. On the other hand, for the impurities carried in the gas, due to the low pressure at the outlet hole 345, the impurities will move toward the outlet hole 345 along with the airflow under the pressure difference, and then flow out of the elbow 341 into the impurity box 32. The discharge hole 345 is blocked by the blocking block 343. When rotating, the arc-shaped plate on the blocking block 343 hits the impact rod 347, and then the discharge hole 345 leaks under the pressure of the two. After the work is finished, the door panel 6 can be opened to remove the impurities.

[0031] For example 3, please refer to Figure 1-12 Based on the first and second embodiments, the present invention provides a technical solution: The outer wall of the refrigeration device 1 is fixedly connected with a heat recovery mechanism 4, and the heat recovery mechanism 4 includes a slide rail 44, and the outer wall of the slide rail 44 is slidably connected with a slider 45, and the outer wall of the slider 45 is fixedly connected with a heat recovery pipe 43, and the outer wall of the heat recovery pipe 43 is fixedly connected with a recovery bin 41, and the outer wall of the recovery bin 41 is fixedly connected with a zigzag pipe 42, and the outer wall of the heat recovery pipe 43 is fixedly connected with a heat outlet 47; The gas after impurity separation rushes to the zigzag pipe 42 of the heat recovery mechanism 4. The zigzag shape of the zigzag pipe 42 increases the contact area and contact time between the gas and the pipe wall. The heat recovery pipe 43 is made of a copper pipe with excellent thermal conductivity. The heat is conducted along the zigzag pipe 42 to the recovery bin 41. The recovery bin 41 is generally wrapped with a material with certain thermal insulation properties, which can reduce heat loss, effectively store and integrate heat, and finally use the heat for the required purpose through the heat outlet 47.

[0032] The zigzag pipe 42 is located outside the bent pipe 341, the outer wall of the impurity box 32 is located near the zigzag pipe 42 and is fixedly connected to the limit ring 5, the top of the slider 45 is threadedly connected with a bolt 46, the outer wall of the heat return pipe 43 is fixedly connected with a heating assembly 48, the heating assembly 48 includes a heating rod 483, the outer wall of the heating rod 483 is fixedly connected to the outer wall of the heat return pipe 43, the bottom of the heating rod 483 is fixedly connected with a heating box 481, the outer wall of the heating box 481 is rotatably connected with a heating plate 482, a detachable frame is movably connected between the heating assembly 48 and the refrigeration device 1, the heating rod 483 is connected to the outer wall of the heat return pipe 43, so the generated heat will be transmitted to the heating box 481 through the heating rod 483, thereby increasing the internal temperature of the heating box 481, placing the things to be heated in the heating box 481, and then turning off the heating plate 482, the temperature can be effectively used to heat the required items; The slider 45 in the heat recovery mechanism 4 can slide on the slide rail 44 to adjust the relative position of the zigzag pipe 42 and the bent pipe 341. When the slider 45 slides on the slide rail 44, the heat recovery pipe 43 fixed on the slider 45 and the zigzag pipe 42 connected thereto will be displaced as a whole, thereby changing the incident angle and impact force of the gas impacting the zigzag pipe 42. When the slider 45 slides in the direction close to the bent pipe 341, the distance between the zigzag pipe 42 and the bent pipe 341 decreases, the angle at which the gas impacts the zigzag pipe 42 will be more vertical, and the impact force will be relatively increased, which may improve the heat transfer efficiency within a certain range. Conversely, when the slider 45 slides in the direction away from the bent pipe 341, the impact angle will become more inclined and the impact force will be relatively reduced. Through such adjustment, an optimal relative position can be found according to the actual operating conditions and heat recovery requirements, thereby optimizing the heat recovery efficiency. After the adjustment is completed, tighten the bolt 46 to fix the slider 45.

[0033] Example 4, please refer to Figure 1-12 , the present invention provides another technical solution: In this embodiment, the heating box 481 can be detached and arranged at a position far away from the refrigeration device 1, and a pipe can be connected to the heat outlet 47, and the other end of the pipe is connected to the heating box 481 at a far away position; The length of the heating rod 483 will also be extended to the refrigeration device 1 at a farther position; A heat recovery device for a refrigeration system of an artificial climate chamber, comprising a refrigeration device 1, an outer wall of the refrigeration device 1 is provided with an exhaust port 2, and a guide mechanism 3 is fixedly connected to the outer wall of the refrigeration device 1; Combined with Figure 1 As shown, when the refrigeration device 1 is in operation, the hot gas generated inside enters the guide bin 33 through the discharge port 2 under pressure, and the guide bin 33 plays a role in initially converging and guiding the airflow, so that the gas can smoothly enter the elbow 341; Guide mechanism 3: An impurity box 32, the impurity box 32 is fixedly connected to the outer wall of the refrigeration device 1; A guide bin 33, the guide bin 33 is fixedly connected to the outer wall of the impurity box 32; The motor 35 is also fixedly connected to the outer wall of the refrigeration device 1; The processing assembly 34 and the outer wall of the motor 35 are rotatably connected to the processing assembly 34 .

[0034] The impurity box 32 is fixedly connected to the outer wall of the refrigeration device 1 through the bracket 31, and the motor 35 is fixedly connected to the outer wall of the guide bin 33; During the process of discharging the airflow from the outlet 2, the impact force of the airflow discharged from the outlet 2 is utilized. After the motor 35 is started, its output shaft drives the connecting rod 346 to make a circular motion, thereby causing the impact rod 347 to rotate around the outer wall of the motor 35. When the impact rod 347 rotates to a position in contact with the blocking block 343, the impact force of the impact rod 347 overcomes the elastic force of the spring 342, forcing the blocking block 343 to move outward along the outer wall of the curved pipe 341, thereby opening the discharge hole 345. At this time, the gas in the curved pipe 341 is quickly discharged from the discharge hole 345 driven by the impact force of the airflow discharged from the outlet 2. When the impact rod 347 continues to rotate and leave the blocking block 343, the elastic force generated by the spring 342 recovers the deformation to pull the blocking block 343 back to the initial position, and close the discharge hole 345 again. This cycle is repeated, and the motor 35 continues to operate stably, so that the gas can be discharged from the curved pipe 341 in a periodic pulsed manner.

When the gas flows in the curved pipe 341, at the curved portion and where the discharge hole 345 is located, because the air flow difference between the discharge hole 345 at the curved portion of the curved pipe 341 and the end of the curved pipe 341 is different, the pressure difference is different, and then the impurities are squeezed under pressure and discharged from the discharge hole 345 into the impurity box 32.

[0040] The bottom of the impurity box 32 is rotatably connected with a door panel 6; According to the Bernoulli equation, the pressure is low where the flow rate is high, and the pressure is high where the flow rate is low. Therefore, a pressure area is formed at the outlet hole 345 of the elbow 341, which is smaller than the end of the elbow 341. This pressure difference produces many positive effects. On the one hand, for the airflow itself, the pressure difference makes the gas more inclined to flow out from the outlet hole 345, ensuring that the gas can be discharged smoothly according to the designed path, avoiding turbulence or retention inside the elbow 341, and maintaining the stable transmission of the airflow. On the other hand, for the impurities carried in the gas, due to the low pressure at the outlet hole 345, the impurities will move toward the outlet hole 345 along with the airflow under the pressure difference, and then flow out of the elbow 341 into the impurity box 32. The discharge hole 345 is blocked by the blocking block 343. When rotating, the arc-shaped plate on the blocking block 343 hits the impact rod 347, and then the discharge hole 345 leaks under the pressure of the two.
