Description

Technical Field

[0001] This utility model relates to the field of cold storage energy-saving technology, specifically to an energy-saving device for cold storage. Background Technology

[0002] Cold storage facilities are essential for storing various perishable foods, medicines, chemical raw materials, and other items in a low-temperature environment. With the improvement of people's living standards and the development of global trade, the demand for fresh food and various items requiring low-temperature preservation is increasing, leading to a continuous expansion in the scale and number of cold storage facilities. The energy consumption of cold storage operations mainly comes from the refrigeration system, which in turn is closely related to the cooling method used in the cold storage.

[0003] Traditional cold storage cooling typically uses direct airflow from fans, where fans are installed inside the cold storage to blow cold air directly out, thus circulating and cooling the air inside. This method suffers from low fan circulation efficiency and high energy consumption, leading to increased operating costs for the cold storage. Furthermore, the short circulation path of the direct airflow from the fans limits the number of times the air circulates within the cold storage, making it difficult to quickly remove heat from the goods and the space inside. This forces the refrigeration system to continuously cool to maintain the temperature inside the storage, increasing the load and operating time of the refrigeration system, and consequently, increasing energy consumption. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving device for cold storage, in order to solve the problem mentioned in the background art that traditional cold storage cooling usually adopts the method of direct air blowing by fans. This method has the problems of low fan circulation efficiency and high energy consumption, which leads to increased operating costs of cold storage and unsatisfactory cooling effect, making it difficult to meet the needs of high efficiency and energy saving.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving device for cold storage, including a cold storage air box, which is a cold storage cooling device, and the cold storage air box is installed in the upper space inside the cold storage. The air supply pipe of the cold storage air box is connected to a conveying pipe, and the conveying pipe constitutes the main pipe for supplying cold air and cooling inside the cold storage.

[0006] The cold storage air box is fitted with a docking frame at the connection between the air box and the conveying pipe. The docking frame has threads on its surface and the threads of the docking frame are connected to the positioning ring. The outer wall of the conveying pipe is fitted with an insulation kit, and a connecting pipe sleeve is provided on each side of the insulation kit.

[0007] Air supply pipe 1 is provided on both sides of the conveying pipe, and a spiral guide frame is installed inside the conveying pipe. The air supply pipe 1 is equidistantly arranged. An insulated corrugated pipe is installed at the bottom end of the air supply pipe 1, and an air supply pipe 2 is connected to the bottom end of the insulated corrugated pipe.

[0008] By adopting the above technical solution, the airflow speed inside the cold storage is increased, and the rate of temperature loss is reduced.

[0009] Preferably, the docking frame consists of two semi-circular structures, and the centers of the docking frame, the positioning ring, and the conveying pipe are aligned.

[0010] By adopting the above technical solution, the detachable docking frame and positioning ring structure facilitates quick disassembly and installation when maintenance or replacement of parts is required, shortening maintenance time and cold storage downtime, and indirectly reducing energy consumption.

[0011] Preferably, the insulation kit consists of an insulation sleeve and insulation cotton, and the insulation kit is wrapped around the outer layer of the conveying pipe, with the conveying pipe installed at a height close to the top of the cold storage.

[0012] The above technical solution protects the conveying pipe from damage caused by long-term hot and cold cycles or contact with the external environment. At the same time, it maintains the low temperature of the cold air during the conveying of cold air, reducing the loss of cooling capacity.

[0013] Preferably, the connecting sleeve is provided with two connecting holes in the vertical and horizontal directions, and the connecting sleeve is at the same height as the air supply pipe.

[0014] The above technical solution provides two connection holes, one vertical and one horizontal, which facilitates flexible connection between the air supply pipe and the delivery pipe, and can adapt to different installation positions and spatial layout requirements.

[0015] Preferably, the spiral guide frame is installed inside the conveying pipe, and the other end of the spiral guide frame is engaged with a protrusion on the inner wall of the positioning plate.

[0016] By adopting the above technical solution, the spiral guide frame is positioned by the positioning plate when installed in the conveying pipe, thus avoiding excessive movement.

[0017] Preferably, the air supply pipe is configured as an L-shaped pipe structure, and the air supply pipe is connected to the spiral space of the spiral guide frame.

[0018] By adopting the above technical solution, the spiral structure can guide the airflow to flow more smoothly. Compared with the straight airflow channel, it can reduce the airflow resistance to a certain extent, reduce the energy consumption of the fan to drive the cold air, and thus achieve energy saving.

[0019] Preferably, a filter screen is fitted onto the inner wall of the air supply duct, and the filter screen consists of two layers of mesh structure and a middle layer of activated carbon.

[0020] By adopting the above technical solution, dust, impurities and odors in the air can be effectively filtered, keeping the air inside the cold storage clean. The purified air helps protect the goods stored in the cold storage, prevents the goods from being contaminated or having odors mixed with the air, and reduces economic losses caused by damage or spoilage of the goods. From another perspective, it achieves resource conservation and energy consumption reduction.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the energy-saving device inside the cold storage:

[0022] 1. After the conveying pipe and cold storage air box are installed, the air supply pipe 1 installed on the side wall of the conveying pipe delivers cold air to various areas of the cold storage. By adding an insulated corrugated pipe, the air supply pipe 2 at the bottom of the insulated corrugated pipe can be moved further. Its position can be flexibly bent and extended according to the actual layout of the cold storage, delivering cold air to all corners of the cold storage. In conjunction with the spiral guide frame installed in the conveying pipe, the cold air forms a spiral flow during transportation, reducing the turbulence and eddy current phenomenon of air in the pipe, reducing air flow resistance, thereby reducing the energy consumption required for the fan to drive the air, and achieving energy saving effect.

[0023] 2. The insulation kit installed around the conveying pipe provides insulation during the transportation process, effectively reducing the loss of cold air during transportation and improving energy efficiency. In addition, the insulated corrugated pipe, by adding an insulation layer to the outer layer, prevents heat loss during the transportation of cold air. Furthermore, the elastic and flexible structure of the corrugated pipe can effectively absorb and reduce the noise and vibration generated by the airflow in the air supply pipe, creating a quieter working environment for cold storage workers.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: an energy-saving device for cold storage, including a cold storage air box 1, a conveying pipe 2, a docking frame 3, a positioning ring 4, a heat preservation kit 5, a connecting pipe sleeve 6, a spiral guide frame 7, a positioning plate 8, an air supply pipe 9, a heat preservation corrugated pipe 10, an air supply pipe 11, and a filter screen 12.

[0033] Among them, the cold storage air box 1 is a cold storage cooling device, and the cold storage air box 1 is installed in the upper space inside the cold storage. The air supply pipe of the cold storage air box 1 is connected to the conveying pipe 2, and the conveying pipe 2 constitutes the main pipe for cold air supply and cooling inside the cold storage.

[0034] A connecting frame 3 is fitted on the outside of the connection between the cold storage air box 1 and the conveying pipe 2. The surface of the connecting frame 3 is threaded and the thread of the connecting frame 3 is connected to the positioning ring 4. The outer wall of the conveying pipe 2 is fitted with an insulation kit 5. A connecting pipe sleeve 6 is set on each side of the insulation kit 5. The connecting frame 3 is composed of two semi-circular structures. The center of the connecting frame 3, the positioning ring 4 and the conveying pipe 2 are aligned. The insulation kit 5 is composed of an insulation sleeve and insulation cotton. The insulation kit 5 is wrapped around the outer layer of the conveying pipe 2. The installation height of the conveying pipe 2 is close to the top of the cold storage. The connecting pipe sleeve 6 is provided with two connecting holes in the vertical and horizontal directions. The height of the connecting pipe sleeve 6 is consistent with that of the air supply pipe 9.

[0035] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the cold storage air box 1, as a cold storage cooling device, is installed in the upper space of the cold storage and is responsible for generating cold air. The refrigeration mechanism inside the air box cools the air to the required low temperature to form a cold air source. The generated cold air enters the delivery pipe 2 from the air supply duct of the cold storage air box 1. The delivery pipe 2, as the main pipeline for cold air supply and cooling in the cold storage, delivers the cold air from the air box to various areas of the cold storage. The docking frame 3, which is externally fitted at the connection between the cold storage air box 1 and the delivery pipe 2, is further limited by the positioning ring 4. By separating the positioning ring 4, it is convenient to install and disassemble the cold storage air box 1 and the delivery pipe 2. At the same time, the installation of the docking frame 3 and the positioning ring 4 and the alignment of the center of the delivery pipe 2 ensure the smoothness and sealing of the cold air delivery.

[0036] The insulation kit 5 consists of an insulation sleeve and insulation cotton, which are wrapped around the outer layer of the delivery pipe 2. This can effectively reduce the loss of cold air during the delivery process and improve energy efficiency. The spiral guide frame 7 is set inside the delivery pipe 2. The other end of the spiral guide frame 7 is engaged with the protrusion on the inner wall of the positioning plate 8 to ensure that its position inside the delivery pipe is fixed. The spiral guide frame 7 divides the space inside the delivery pipe 2 into a spiral environment, so that the cold air forms a spiral flow inside the delivery pipe. This flow mode can reduce the turbulence and eddy current phenomenon of air in the pipe, reduce the air flow resistance, thereby reducing the energy consumption required for the fan to drive the air and achieving energy saving. Together with the wrapping of the insulation kit 5, the temperature inside the pipe is maintained. The insulation kit 5 and the connecting pipe sleeve 6 work together to form a structure that helps stabilize the installation of the delivery pipe 2.

[0037] In addition, spiral flow can prolong the contact time between cold air and the duct wall, making the cold energy transfer more complete, which helps to maintain the stability of the temperature inside the cold storage, reduce the number of times the refrigeration system is started, and thus reduce energy consumption.

[0038] Air supply pipes 9 are provided on both sides of the conveying pipe 2, and a spiral guide frame 7 is installed inside the conveying pipe 2. The air supply pipes 9 are equidistant. A heat-insulating corrugated pipe 10 is installed at the bottom of the air supply pipe 9, and the bottom of the heat-insulating corrugated pipe 10 is connected to the air supply pipe 11. The spiral guide frame 7 is set inside the conveying pipe 2, and the other end of the spiral guide frame 7 is engaged with the protrusion on the inner wall of the positioning plate 8. The air supply pipe 9 is set as an L-shaped pipe structure, and the spiral space of the air supply pipe 9 and the spiral guide frame 7 are connected. A filter screen 12 is engaged and installed on the inner wall of the air supply pipe 11. The filter screen 12 is composed of two layers of mesh structure and a middle layer of activated carbon.

[0039] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, the air supply ducts 1-9 installed on both sides of the conveying pipe 2 supply cold air. The insulated corrugated pipe 10 installed at the bottom of the air supply duct 1-9 has good flexibility and insulation performance, and can be flexibly bent and extended according to the actual layout of the cold storage to deliver cold air to all corners of the cold storage. At the same time, its insulation performance can reduce the cold loss of cold air during transmission. The air supply duct 2-11 installed at the bottom of the insulated corrugated pipe 10 provides a place for the filter screen 12. During this process, the cold air diverted from the air supply duct 1-9 is finally delivered through the air supply duct 2-11. Figure 2-6 As shown, the air is blown towards the goods and space inside the cold storage to achieve cooling. The three-layer structure of the filter 12 can filter out dust, impurities, etc. that may be carried in the cold air, keeping the air inside the cold storage clean.

[0040] Working Principle: When using this energy-saving device in the cold storage, cold air is generated by the cold storage air box 1 installed in the upper space of the cold storage. This cold air is then delivered to various areas of the cold storage via the delivery pipe 2. The connection between the cold storage air box 1 and the delivery pipe 2 is ensured by the cooperation of the docking frame 3 and the positioning ring 4. The insulation kit 5, wrapped around the outer layer of the delivery pipe 2, effectively reduces the loss of cold air during delivery. Simultaneously, the spiral guide frame 7 inside the delivery pipe 2 causes the cold air to flow in a spiral pattern within the pipe. This flow pattern reduces turbulence and eddies within the pipe, minimizing airflow. Resistance, the connecting pipe sleeve 6 of the outer layer of the insulation kit 5 is connected to the mounting frame through internal holes, used to connect and fix the air supply pipe 9. With the air supply pipe 9 set at equal intervals, multiple outlets are provided for cold air. The bottom end of the air supply pipe 9 is equipped with an insulated corrugated pipe 10, which can be flexibly bent and extended according to the actual layout of the cold storage, so as to deliver cold air to all corners of the cold storage. The filter screen 12 set in the inner layer of the air supply pipe 11 can filter out dust, impurities and other substances that may be carried in the cold air. At the same time, the activated carbon layer can also absorb odors, providing a clean and hygienic storage environment for goods and increasing the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
