Technical Field

[0001] The present invention relates to the field of precooling devices, and particularly to a cold source position control device for a refrigeration system. Background Art

[0002] Cold storages have always been an important part of the logistics industry. Cold storages are mainly used for the constant temperature and humidity storage of semi-finished and finished products such as food, dairy products, meat, aquatic products, poultry, fruits and vegetables, beverages, flowers, green plants, tea, pharmaceuticals, chemical raw materials, electronic instrumentation, tobacco, and alcoholic beverages. Cold storages belong to a type of refrigeration equipment, and their refrigeration area is much larger compared to refrigerators, but they have the same refrigeration principle.

[0003] When placing items in a cold storage, some items have poor tolerance to temperature differences. When the temperature difference changes too much, the items will be frozen under rapid cooling, thereby affecting the quality of the items. Therefore, it is necessary to pre-cool the items before putting them into the cold storage to reduce the problems of the items themselves, thereby reducing the temperature difference between the temperature of the items themselves and the temperature in the cold storage. Existing pre-cooling systems mostly use splashing cold water or blowing cold air to pre-cool the goods, with relatively low pre-cooling efficiency. At the same time, during the pre-cooling process of the items, the items cannot be transported into the cold storage, increasing the waiting time, and thus increasing the entire transportation time.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] An embodiment of a method for controlling the cold source position of a refrigeration system according to the present invention, as Figures 1 to 2 shown, a method for controlling the cold source position of a refrigeration system includes the following steps:

[0039] S1. Collect the first temperature information and the second temperature information of the item. The first temperature information is the temperature information of the item at room temperature, and the first temperature information is also the initial temperature of the item when it is placed on the conveying device; the second temperature information is the temperature information of the item's ability to withstand temperature difference changes.

[0040] S2. Classify the items according to the magnitudes of the first temperature information and the second temperature information of the items; based on the different first temperature information, the problems inside the item and the cold storage can be calculated. When the temperature difference is within the safe range, the magnitude of the second temperature information does not need to be considered. When the temperature difference is large, the items are mainly classified according to the second temperature information. The items are classified according to the temperature information of the item at room temperature and the item's ability to withstand temperature difference changes.

[0041] S3. According to the classification structure of the items, adjust the conveying duration of the items by the conveying transposition. The conveying device conveys the items with strong ability to withstand temperature difference changes to the cold storage at the first preset time; the conveying device conveys the items with weak ability to withstand temperature difference changes to the cold storage at the second preset time. The first preset time is less than the second preset time. Thus, when conveying the items with strong ability to withstand temperature difference changes, the conveying time can be accelerated to increase the conveying efficiency.

[0042] A method for controlling the cold source position of a refrigeration system, the conveying device includes a first conveying part, a second conveying part and an Nth conveying part; the first conveying part is communicated with the cold storage;

[0043] Step S3 further includes: according to the classification of the items, adjust the distance between multiple conveying positions. The distance between the conveying positions can determine the time for the items to be conveyed to the cold storage; when the items are conveyed from the Nth conveying position through the second conveying position to the first conveying position, the temperature is gradually reduced to the third temperature information.

[0044] First, collect the first temperature information and the second temperature information of the items, classify the items according to the first temperature information and the second temperature information. The conveying device conveys the items with strong ability to withstand temperature difference changes to the cold storage at the first preset time; the conveying device conveys the items with weak ability to withstand temperature difference changes to the cold storage at the second preset time. The first preset time is less than the second preset time. Thus, when conveying the items with strong ability to withstand temperature difference changes, the conveying time can be accelerated to increase the conveying efficiency, and at the same time, there is a pre-cooling effect on the items with weak ability to withstand temperature difference changes, preventing the items from being frozen when directly placed in the cold storage.

[0045] An embodiment of a device for controlling the cold source position of a refrigeration system according to the present invention, as Figures 2 to 10 shown, a device for controlling the cold source position of a refrigeration system includes a cold storage, a bracket 100, a first cooling barrel 200, a second cooling barrel 300, a third cooling barrel 400, a cooling pipe 500 and a driving mechanism 600. The cold storage is used for refrigerating items, and the bracket 100 is arranged on one side of the cold storage. The first cooling barrel 200 is horizontally and rotatably arranged on the bracket 100. The left end of the first cooling barrel 200 is provided with a feed inlet. Specifically, the left end of the first cooling barrel 200 is open, and the right end is the bottom of the first cooling barrel 200. The inner wall of the first cooling barrel 200 is provided with spiral protrusions. When the first cooling barrel 200 rotates, the items are guided to the right. The threaded protrusions on the inner wall of the first cooling barrel 200 extend spirally from the left end to the right end of the first cooling barrel 200, so as to gradually drive the items to the right through the protrusions on the inner wall of the first cooling barrel 200 when the first cooling barrel 200 rotates.

[0046] The second cooling barrel 300 is disposed within the first cooling barrel 200 and is coaxial with the first cooling barrel 200; the opening of the second cooling barrel 300 is located at the right end of the second cooling barrel 300, and the bottom of the second cooling barrel 300 is located at the left end. The second cooling barrel 300 rotates synchronously with the first cooling barrel 200. Specifically, a plurality of synchronous grooves 310 are uniformly distributed on the outer peripheral wall of the second cooling barrel 300; the synchronous grooves 310 extend along the axial direction of the second cooling barrel 300; a synchronous slider 320 is inserted into each synchronous groove 310; the synchronous slider 320 slides along the synchronous groove 310; the synchronous slider 320 is fixedly connected to the first cooling barrel 200. A spiral protrusion is provided on the inner wall of the second cooling barrel 300, and the spiral direction of the spiral protrusion in the second cooling barrel 300 is opposite to that of the spiral protrusion in the first cooling barrel 200. When the second cooling barrel 300 rotates, the items are guided from the right end to the left side of the second cooling barrel 300 through the spiral protrusion in the second cooling barrel 300. A first guiding assembly 700 is provided at the right end of the second cooling barrel 300, and the first guiding assembly 700 is used to introduce the items at the right end of the first cooling barrel 200 into the second cooling barrel 300. Specifically, the first cooling barrel 200 conveys the items to the right end of the second cooling barrel 300, and the first guiding assembly 700 introduces the items in the first cooling barrel 200 into the second cooling barrel 300; the driving mechanism 600 is used to drive the second cooling barrel 300 to rotate.

[0047] The third cooling barrel 400 is disposed within the second cooling barrel 300 and is coaxial with the second cooling barrel 300. The third cooling barrel 400 is tubular and has openings at both ends. The right end of the third cooling barrel 400 penetrates through the first cooling barrel 200, is fixedly connected to the first cooling barrel 200, and can communicate with the cold storage. Specifically, the third cooling barrel 400 rotates synchronously with the first cooling barrel 200, and the items can enter the cold storage from the third cooling barrel 400. A spiral protrusion is provided on the inner wall of the third cooling barrel 400. When the third cooling barrel 400 rotates, the items are guided to the right, so that when the third cooling barrel 400 rotates, the items are guided into the cold storage through the spiral protrusion on the third cooling barrel 400. A second guiding assembly 800 is provided at the left end of the third cooling barrel 400; the second guiding assembly 800 is used to introduce the items at the left end of the second cooling barrel 300 into the third cooling barrel 400.

[0048] The cooling pipe 500 is inserted into the third cooling barrel 400. The temperature of the cooling pipe 500 is close to the internal temperature of the cold storage. Thus, when the items in the third cooling barrel 400 are transported into the cold storage, the temperature difference between the items and the cold storage reaches a safe value. Further, ventilation holes are provided on the first cooling barrel 200, the second cooling barrel 300, and the third cooling barrel 400, or the first cooling barrel 200, the second cooling barrel 300, and the third cooling barrel 400 are all made of heat-conductive materials. Thus, the temperature gradually decreases from the first cooling barrel 200 to the second cooling barrel 300 and then to the third cooling barrel 400, so that the temperature of the items gradually decreases during the transportation from the first cooling barrel 200 to the third cooling barrel 400. Specifically, the third cooling barrel 400 is the first conveying position, the second cooling barrel 300 is the second conveying position, and the first cooling position is the Nth conveying position.

[0049] In this embodiment, as Figures 3 to 8 shown, the first guiding assembly 700 includes a first guiding block 710 and a plurality of first guiding plates 720. The first guiding block 710 is frustum-shaped. The first guiding block 710 is slidably sleeved on the third cooling barrel 400 and is located at the opening at the right end of the second cooling barrel 300. The diameter of the left end of the first guiding block 710 is smaller than that of the right end. Thus, when an item falls on the first guiding block 710, the inclined surface on the first guiding block 710 will guide the item into the second cooling barrel 300. The plurality of first guiding plates 720 are evenly distributed circumferentially along the first guiding block 710. The first guiding plates 720 are rectangular plates. The length of the first guiding plate 720 coincides with the radial direction of the first guiding block 710, and the width is parallel to the axis of the first cooling barrel 200. One end of the first guiding plate 720 is fixedly connected to the first guiding block 710, and the other end is in contact with the inside of the first cooling barrel 200. One long side of the first guiding plate 720 is fixedly connected to the right end of the second cooling barrel 300, so that the first guiding plate 720, the first guiding block 710, and the second cooling barrel 300 rotate synchronously. Specifically, when the first cooling barrel 200 and the second cooling barrel 300 rotate synchronously, the first guiding plate 720 will drive the item at the right end of the first cooling barrel 200 along the rotation direction of the first cooling barrel 200. When the item is driven by the first guiding plate 720 to a preset height, the item will slide along the first guiding plate 720 in the axial direction of the second cooling barrel 300, so that the item contacts the first guiding block 710. The first guiding block 710 guides the item into the second cooling barrel 300, thus completing the transfer of the item from the first cooling barrel 200 to the second cooling barrel 300.

[0050] The second guiding component 800 includes a second guiding block 810 and a plurality of second guiding plates 820. The second guiding block 810 is conical. The second guiding block 810 is located at the opening at the left end of the third cooling barrel 400. The second guiding block 810 is coaxial with the third cooling barrel 400, and the vertex extends into the third cooling barrel 400 to guide the articles falling on the second guiding block 810 into the third cooling barrel 400. The plurality of second guiding plates 820 are evenly distributed along the second guiding block 810; the second guiding plates 820 are fixedly arranged at the left end of the third cooling barrel 400, and the length coincides with the radial direction of the third cooling barrel 400, and the width is parallel to the axial direction of the third cooling barrel 400; one end of the second guiding plate 820 is fixedly connected to the second guiding block 810, and the other end is in contact with the inner wall of the second cooling barrel 300. One long side of the second guiding plate 820 is fixedly connected to the left end of the third cooling barrel 400, so that the second guiding block 810, the second guiding plates 820 and the third cooling barrel 400 rotate synchronously. Specifically, when the second cooling barrel 300 and the third cooling barrel 400 rotate synchronously, the second guiding plates 820 drive the articles at the left end in the second cooling barrel 300 upward along the rotation direction of the second cooling barrel 300. When the articles are driven by the second guiding plates 820 to a preset height, the articles slide along the second guiding plates 820 in the axial direction of the third cooling barrel 400, so that the articles come into contact with the second cooling block, and the second cooling block guides the articles into the third cooling barrel 400, thereby completing the transfer of the articles from the second cooling barrel 300 to the third cooling barrel 400.

[0051] In this embodiment, as Figures 3 to 6As shown, the bracket 100 includes a mounting plate 110, a sliding plate 120, a first hydraulic cylinder 140, and a fixing plate 130. The first cooling barrel 200 and the second cooling barrel 300 can slide relative to each other in the axial direction, and the first cooling barrel 200 and the third cooling barrel 400 are fixedly connected, so that the third cooling barrel 400 and the second cooling barrel 300 can slide relative to each other in the axial direction. The mounting plate 110 is horizontally arranged on the ground; the fixing plate 130 is vertically arranged and fixed on the mounting plate 110, and the left end of the second cooling barrel 300 is rotatably arranged on the fixing plate 130. The sliding plate 120 and the fixing plate 130 are parallel to each other, and the sliding plate 120 is slidably arranged on the mounting plate 110. When the sliding plate 120 slides, the distance between the sliding plate 120 and the fixing plate 130 changes. Specifically, the inscribed circles between the sliding plate 120 and the fixing plate 130 are coaxial. The third cooling barrel 400 is rotatably arranged on the sliding plate 120, so that when the sliding plate 120 slides, it can drive the third cooling barrel 400 to slide, and at the same time drive the first cooling barrel 200 to slide, thereby changing the axial overlapping length of the first cooling barrel 200 and the second cooling barrel 300 and the axial overlapping length of the second cooling barrel 300 and the third cooling barrel 400. When both overlapping lengths become smaller, the conveying time from the first cooling barrel 200 to the third cooling barrel 400 becomes shorter, so that some items with strong ability to withstand temperature difference changes can be transported while ensuring the conveying efficiency. When both overlapping lengths become larger, the conveying time from the first cooling barrel 200 to the third cooling barrel 400 becomes longer, and the temperature of the items slowly drops during the conveying process, so as to transport some items with weak ability to withstand temperature difference changes. The first hydraulic cylinder 140 is fixedly arranged on the mounting plate 110, and the hydraulic shaft of the first hydraulic cylinder 140 is fixedly connected to the sliding plate 120. Thus, the first hydraulic cylinder 140 can drive the sliding plate 120 to slide on the fixing plate 130 through the hydraulic shaft. A driving motor 610 is provided on the fixing plate 130; the driving mechanism 600 is the driving motor 610, and the output shaft of the driving motor 610 is connected to the second cooling barrel 300 through a transmission belt 620 to drive the second cooling barrel 300 to rotate.

[0052] In this embodiment, as Figures 6 to 10As shown in the figure, a refrigerating gas flows through the cooling pipe 500. The cooling pipe 500 is provided with a plurality of communication grooves 510, and the plurality of communication grooves 510 are uniformly distributed in the circumferential direction of the cooling pipe 500 and are also uniformly distributed in the axial direction. The communication grooves 510 extend along the axial direction of the cooling pipe 500 and are parallel to the axis of the cooling pipe 500; the communication grooves 510 penetrate through the circumferential wall of the cooling pipe 500 in the radial direction of the cooling pipe 500. A sealing plate 520 is provided on each communication groove 510. The sealing plate 520 is located inside the cooling pipe 500, and the sealing plate 520 can slide along the length direction of the communication groove 510. Specifically, the sealing plate 520 can slide left and right. The sealing plate 520 is used to seal the communication groove 510 so as to always block the sealing plate 520 when the sealing plate 520 slides left and right. A communication hole 550 is provided on each sealing plate 520, and the refrigerating gas in the cooling pipe 500 can enter the third cooling barrel 400 through the communication hole 550. A plurality of cooling rings 530 are slidably sleeved on the cooling pipe 500. The cooling rings 530 are in an annular tubular shape, and a plurality of holes communicating with the third cooling barrel 400 are circumferentially and uniformly distributed on the circumferential wall. Each cooling ring 530 is fixedly connected to a sealing plate 520 and is communicated with the communication hole 550 on the sealing plate 520, so that the refrigerating gas enters the cooling ring 530 from the communication hole 550 and then enters the third cooling barrel 400 through the holes on the cooling ring 530. The holes on the cooling ring 530 enable the refrigerating gas to be uniformly diffused. A spring 540 is provided between two adjacent cooling rings 530. Two ends of the spring 540 are respectively fixedly connected to the two adjacent cooling rings 530, so that when the rightmost cooling ring 530 slides leftward, a plurality of springs 540 are synchronously compressed, thereby shortening the distance between two adjacent cooling rings 530. A second hydraulic cylinder 150 is provided on the cooling pipe 500. The second hydraulic cylinder 150 is arranged on the cooling pipe 500, and the hydraulic shaft of the second hydraulic cylinder 150 is fixedly connected to the rightmost cooling ring 530; the first hydraulic cylinder 140 is electrically connected to the second hydraulic cylinder 150, so that the telescopic directions of the hydraulic shafts of the first hydraulic cylinder 140 and the second hydraulic cylinder 150 are opposite and the telescopic amounts are the same. Further, after the first hydraulic cylinder 140 drives the sliding plate 120 to slide leftward or rightward by a certain distance, the second hydraulic cylinder 150 drives the rightmost cooling ring 530 to slide rightward or leftward by the same distance, thereby shortening the distance between adjacent cooling rings 530, and further improving the refrigeration efficiency when the conveying distance is short.

[0053] During operation, first collect the strength information of the large temperature difference changes suffered by the items to be refrigerated and stored, and classify them according to the strength of the temperature difference suffered by the items. In the initial state, the sliding plate 120 is located at the leftmost end of the fixed plate 130, and the overlapping parts of the axial directions between the first cooling barrel 200 and the second cooling barrel 300, and between the second cooling barrel 300 and the third cooling barrel 400 are the largest.

[0054] Turn on the drive motor 610, and the drive motor 610 drives the first cooling barrel 200, the second cooling barrel 300, and the third cooling barrel 400 to rotate synchronously. At the same time, introduce a refrigerating gas into the cooling pipe 500, and the refrigerating gas diffuses into the third cooling barrel 400 through the communication holes 550 and the refrigerating ring, thereby gradually cooling the third cooling barrel 400, the second cooling barrel 300, and the first cooling barrel 200.

[0055] First, introduce the items that are less resistant to temperature differences into the opening at the left end of the first cooling barrel 200. When the items enter the first cooling barrel 200, their temperatures are initially cooled. When the first cooling barrel 200 rotates, through the spiral protrusions provided on the inner wall, the items are driven to gradually move to the right side of the first cooling barrel 200. The first guide plate 720 drives the items located at the right end of the first cooling barrel 200 along the rotation direction of the first cooling barrel 200. When the items are driven by the first guide plate 720 to a preset height, the items slide along the first guide plate 720 in the axial direction of the second cooling barrel 300, so that the items come into contact with the first guide block 710. The first guide block 710 guides the items into the second cooling barrel 300, thereby completing the transfer of the items from the first cooling barrel 200 to the second cooling barrel 300. The temperatures of the items are further cooled after entering the second cooling barrel 300.

[0056] When the second cooling barrel 300 rotates, the items are transferred from the right end to the left end of the second cooling barrel 300 through the spiral protrusions on the inner wall. When the second cooling barrel 300 and the third cooling barrel 400 rotate synchronously, the second guide plate 820 drives the items located at the left end inside the second cooling barrel 300 upward along the rotation direction of the second cooling barrel 300. When the items are driven by the second guide plate 820 to a preset height, the items slide along the second guide plate 820 in the axial direction of the third cooling barrel 400, so that the items come into contact with the second cooling block. The second cooling block guides the items into the third cooling barrel 400, thereby completing the transfer of the items from the second cooling barrel 300 to the third cooling barrel 400. The temperatures of the items are further cooled after entering the third cooling barrel 400, so that the temperatures of the items are close to the temperature inside the cold storage. The third cooling barrel 400 transports the items into the cold storage through the spiral protrusions on the inner wall.

[0057] Further, open the first hydraulic cylinder 140. When the first hydraulic cylinder 140 is opened, the first hydraulic cylinder 140 drives the sliding plate 120 to slide rightward by a certain distance through the hydraulic shaft, thereby reducing the overlapping part of the axial directions between the first cooling barrel 200 and the second cooling barrel 300, and between the second cooling barrel 300 and the third cooling barrel 400. The second hydraulic cylinder 150 drives the rightmost cooling ring 530 to slide leftward by the same distance, so as to shorten the distance between adjacent cooling rings 530. Then, first introduce the items that are more strongly affected by the temperature difference change into the opening at the left end of the first cooling barrel 200. The items are transported to the cold storage for storage through the second cooling barrel 300 and the third cooling barrel 400 at a relatively fast speed.

[0058] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
