Description

Technical Field

[0001] This application relates to the technical field of cold storage, and particularly to a horizontal air curtain system for cold storage. Background Art

[0002] An air curtain machine is an air purification device that generates a powerful air current through a high-speed motor driving a cross-flow or centrifugal air wheel to form an "invisible curtain". It can be used in environments such as shopping malls, theaters, hotels, restaurants, conference halls, cold storages, operating rooms, and homes. For the air curtain machine used in a cold storage, when blocking the temperature inside and outside the cold storage with a vertically downward parallel air current, due to its product structure, it will inhale a large amount of low-temperature air and contact with the external normal-temperature air, thus causing ice and frost accumulation and affecting the air volume. Therefore, it cannot reliably ensure the appropriate temperature specified in the cold storage, resulting in losses of goods in the cold storage and increasing the maintenance cost of a large number of air curtain machines and the refrigeration energy consumption of the cold storage. Summary of the Invention

[0003] In order to improve the heat insulation and cold preservation effect of the cold storage, this application provides a horizontal air curtain system for cold storage.

[0004] The horizontal air curtain system for cold storage provided by this application is realized through the following solutions:

[0005] A horizontal air curtain system for cold storage includes columns located on both sides of the cold storage inlet and outlet. The two columns are arranged opposite to each other. On the opposite surfaces of the two columns, a number of air inlet and outlet groups are evenly distributed along the vertical direction. Any one of the air inlet and outlet groups includes an air inlet and an air outlet, and the air inlets and air outlets of any one of the air inlet and outlet groups are arranged in groups in the horizontal direction. Jet air outlet components are installed inside the columns corresponding to the positions of the air outlets; on the columns opposite to the relative sides of any one of the air inlets, the corresponding positions are set as air outlets, and on the columns opposite to the relative sides of any one of the air outlets, the corresponding positions are set as air inlets.

[0006] By adopting the above technical solutions, the high-pressure low / high-temperature gases on both sides of the air curtain system are blocked by the parallel strong air current, so that convection cannot occur, and the external high-humidity hot air flow stays outside the cold storage body, which can effectively avoid problems such as insufficient air volume, low air curtain efficiency, and ice and frost accumulation. Moreover, it is formed by modular structure assembly, with a unified structure and simple assembly, realizing the adaptability to multiple cold storage environments and multiple uses.

[0007] In some embodiments, the air inlets and air outlets on any one of the columns are arranged in columns on different vertical planes respectively.

[0008] In some embodiments, based on the upright columns, it is divided into an upper air curtain unit and a lower air curtain unit in the vertical direction. The air inlets and outlets in the upper air curtain unit and the lower air curtain unit are arranged in columns on different vertical planes respectively, and the air inlets in the upper air curtain unit and the air outlets in the lower air curtain unit are arranged in columns on the same vertical plane.

[0009] By adopting the above technical solution, a front, rear, upper and lower quadruple air curtain is formed. Its air duct design is reasonable, the product has high reliability, can effectively avoid the defect of insufficient cold storage insulation caused by insufficient air volume, and can reduce the operation energy consumption and maintenance cost of the air curtain machine.

[0010] In some embodiments, inside any one of the upright columns, a heat exchange component is provided between adjacent air inlets and outlets in any horizontal direction.

[0011] By adopting the above technical solution, the heat exchanger component can be selected and matched according to the actual use situation, generally used when the temperature difference between the inside and outside of the cold storage is large, and it can further improve the heat insulation and cold preservation effect of the cold storage.

[0012] In some embodiments, the jet air outlet component includes a housing and an air jet unit located inside the housing. The air jet unit includes a fan and an air ejector communicated with the fan.

[0013] In some embodiments, air guide plates are distributed at the air outlets. The air guide plates are all arranged horizontally, and both sides are hinged to the air outlets. In addition, a wind direction / wind speed adjustment mechanism is provided. The wind direction / wind speed adjustment mechanism is connected to the air guide plates and drives the air guide plates to adjust the angles.

[0014] By adopting the above technical solution, the wind direction / wind speed adjustment mechanism can flexibly adjust the wind direction and wind speed of the upper air curtain unit and the lower air curtain unit, strengthen the circulating air flow and avoid the phenomenon of head-on collision of opposite air flows.

[0015] In some embodiments, the wind direction / wind speed adjustment mechanism is a parallelogram link structure.

[0016] In some embodiments, the wind direction / wind speed adjustment mechanism includes gears coaxially fixed to a hinge shaft. At least one side of each air guide plate is correspondingly provided with a gear. In addition, a rack is provided, and the rack meshes with the gears on the same side of all the air guide plates at the same time.

[0017] In some embodiments, the upper parts of the two upright columns are connected by a top plate.

[0018] In some embodiments, the inner sides of the upright columns are covered with a heat preservation layer and a sound insulation layer, and sealing and shock-absorbing strips are filled at the joints between the upright columns and the cold storage door and / or between the upright columns and the top plate.

[0019] By adopting the above technical solution, it can not only further improve the heat insulation and cold preservation effect of the cold storage, but also has good sound insulation and shock absorption effects, and can effectively isolate air leakage.

Detailed implementation mode

[0034] The following will further elaborate on this application in conjunction with the attached Figures 1-8 drawings.

[0035] Embodiment 1

[0036] This application provides a horizontal air curtain system for cold storage, as Figure 1 shown in Figure 2 the figure, which includes columns 1 located on both sides of the cold storage inlet and outlet. The two columns 1 are connected by a top plate 4 above. The columns 1 and the top plate 4 are both formed by sheet metal. The sheet metal material is preferably galvanized steel sheet, stainless steel sheet, or aluminum-magnesium alloy sheet, so that the product can have sufficient weather resistance and mechanical properties. The inner sides of the columns 1 and the inner side of the top plate 4 are both covered with a heat preservation layer and a sound insulation layer. The heat preservation layer can be made of rubber and plastic insulation board, extruded board, ordinary foam board, polyurethane insulation board, rock wool, etc., and the material is selected according to specific waterproof requirements and heat preservation performance requirements. The sound insulation material can be corrugated sponge, industrial felt and other materials. The joints between the columns 1 and the cold storage door and / or between the columns 1 and the top plate 4 are filled with sealing and shock-absorbing strips, so that the product has good sound insulation and shock-absorbing effects and can effectively isolate air leakage.

[0037] The two side columns 1 are arranged opposite to each other. On the opposite surfaces of the two side columns 1, several groups of air inlet and outlet groups are evenly distributed along the vertical direction, as Figure 1 shown in Figure 2 the figure. Any group of air inlet and outlet groups includes an air inlet 111 and an air outlet 112, and the air inlets 111 and air outlets 112 of any group of air inlet and outlet groups are arranged in groups in the horizontal direction. The number of air inlets 111 and air outlets 112 in any group of air inlet and outlet groups is not limited, but the air inlets 111 on any column 1 need to be arranged opposite to the air outlets 112 on the other column, so as to ensure that the air beam blown out from one column 1 can be horizontally blown into the air inlet 111 of the opposite side column 1 and blown out again through the air outlet 112 in the same horizontal direction and enter the air inlet 111 of the opposite side column 1 again to achieve circulation.

[0038] In this implementation mode of this application, as Figure 1 shown in Figure 2As shown, any set of air inlet and outlet groups on any column 1 includes an air inlet 111 and an air outlet 112. The air inlet 111 and the air outlet 112 are arranged in columns on different vertical planes respectively. That is, any column 1 includes a column of air inlets 111 and a column of air outlets 112. And at the corresponding position on the column 1 opposite to the relative side of any air inlet 111, an air outlet 112 is provided, and at the corresponding position on the column 1 opposite to the relative side of any air outlet 112, an air inlet 111 is provided.

[0039] As Figure 2 and Figure 3 shown, a jet air outlet assembly 2 is installed at the position corresponding to the air outlet 112 inside the column 1. As Figure 3 shown, the jet air outlet assembly 2 includes a housing and an air jetting unit located inside the housing. The housing is made of sheet metal material, and the sheet metal material is preferably galvanized steel sheet, stainless steel sheet, or aluminum magnesium alloy sheet, so that the product can have sufficient strong weather resistance and mechanical properties.

[0040] As Figure 3 shown, the air ejector 212 includes a fan 211 and an air ejector 212 communicated with the fan 211. The air ejector 212 is a wind guiding channel with an air inlet larger than the air outlet. Therefore, the air passing through the air ejector 212 is compressed at the air outlet, thereby increasing the air pressure. In this embodiment of the present application, the fan 211 adopts a centrifugal fan. Therefore, it can not only meet the structural design of the air jetting port, but also significantly improve the air outlet performance of the product. The housing material of the fan 211 is made of sheet metal material, and the sheet metal material is preferably galvanized steel sheet, stainless steel sheet, or aluminum magnesium alloy sheet, which can make the product have sufficient strong weather resistance and have sufficient reliability under long-term low temperature, humidity, etc.

[0041] The jet air outlet assembly 2 is connected with an electric control module, so as to realize the air outlet of the product, and the air speed and time are controllable, which greatly optimizes the energy consumption of the air curtain machine product. When the cold storage door is closed, the air curtain can be selected to be closed. When the cold storage door needs to be opened, the air curtain machine can be turned on in advance to prevent hot air from invading and cold air from leaking out.

[0042] As Figure 2 shown, inside any column 1, a heat exchange component 3 can also be provided between any horizontally adjacent air inlet 111 and air outlet 112. The heat exchange component 3 is a coil heat exchanger. The heat exchange component 3 can be selected according to the actual use situation, and is generally adopted when the temperature difference between the inside and outside of the cold storage is large. The heat exchange component 3 can be selected to be incorporated into the cold storage refrigeration system or used as an independent refrigeration system. The drainage of the heat exchange component 3 needs to be connected to the cold storage drainage system.

[0043] Embodiment 2

[0044] The horizontal air curtain system for cold storage provided by the embodiment of the present application has basically the same structure as that in Embodiment 1, except that the heat exchange component 3 is not arranged between any adjacent air inlets 111 and air outlets 112 in the horizontal direction. For example, Figure 4 As shown, in this embodiment of the present application, the heat exchange component 3 is located at the position of the air inlet 111, and its area can completely cover all the air inlets 111, so that the heat exchange component 3 can achieve a better heat exchange effect.

[0045] Embodiment 3

[0046] For example, Figure 5 As shown, the structure of Embodiment 2 of the present application is basically the same as that of Embodiment 1 or Embodiment 2, except that the air duct design is different.

[0047] For example, Figure 5 As shown, in this embodiment of the present application, based on the column 1, it is divided into an upper air curtain unit 01 and a lower air curtain unit 02 in the vertical direction. Any one of the air inlet and outlet groups in each of the upper air curtain unit 01 and the lower air curtain unit 02 includes an air inlet 111 and an air outlet 112, and the air inlets 111 and the air outlets 112 are arranged in columns on different vertical planes respectively. At the same time, the air inlets 111 in the upper air curtain unit 01 and the air outlets 112 in the lower air curtain unit 02 are arranged in columns on the same vertical plane. Thus, a four-fold air curtain in the front, rear, upper, and lower directions is formed.

[0048] The air duct design in this embodiment of the present application is reasonable, and the product has high reliability. It can effectively avoid the defect of insufficient cold storage insulation caused by insufficient air volume, and can reduce the operation energy consumption and maintenance cost of the air curtain machine.

[0049] Embodiment 4

[0050] The horizontal air curtain system for cold storage disclosed in Embodiment 4 of the present application is an improved scheme of Embodiment 5, and its structure is basically the same as that in Embodiment 5, except that, for example, Figure 6 As shown, air guide plates 2121 are respectively distributed at the air outlets 112 of the upper air curtain unit 01 and the lower air curtain unit 02. The air guide plates 2121 are all arranged horizontally. A hinge shaft 2100 is horizontally fixed in the middle of the air guide plates 2121, and the air guide plates 2121 are hinged to the inside on both sides of the air outlet 112 through the hinge shaft 2100. In addition, a wind direction / wind speed adjustment mechanism 2120 is provided to cooperate with the air guide plates 2121. The wind direction / wind speed adjustment mechanism 2120 is connected to the air guide plates 2121 to drive the air guide plates 2121 to adjust the angle.

[0051] In this embodiment of the present application, the wind direction / wind speed adjustment mechanism 2120 is a parallelogram link structure, such as Figure 7 and Figure 8As shown in the figure, the wind direction / wind speed adjustment mechanism 2120 includes a connecting rod 2001 located on one side of the vertical column 1 and fixedly connected to each hinge shaft 2100, and a vertical rod 2002 that is hinged to all the connecting rods 2001 at the same time. All the connecting rods 2001 are parallel to each other, and the vertical rod 2002 is vertically arranged. Therefore, by driving one of the hinge shafts 2100, all the connecting rods 2001 are driven to rotate around the hinge shaft 2100 to which they are connected under the linkage of the vertical rod 2002, thereby driving the rotation of the remaining hinge shafts 2100, and then realizing the adjustment of the angle of the air deflector 2121.

[0052] The air deflectors 2121 on the upper air curtain unit 01 and the lower air curtain unit 02 are adjusted separately and are not linked.

[0053] The wind direction / wind speed adjustment mechanism 2120 can flexibly adjust the wind direction and wind speed of the upper air curtain unit 01 and the lower air curtain unit 02, strengthen the circulating air flow, and avoid the phenomenon of head-on collision of opposite air flows.

[0054] In addition, the hinge shaft 2100 as the driving part can be driven by a motor, and the motor can be connected to the electronic control module.

[0055] Embodiment 5

[0056] The horizontal air curtain system for cold storage disclosed in Embodiment 5 of the present application is basically the same as that in Embodiment 4, and the difference lies in the different structure of the wind direction / wind speed adjustment mechanism 2120.

[0057] As Figure 9 and Figure 10 shown, in this embodiment of the present application, the wind direction / wind speed adjustment mechanism 2120 includes a gear 2005 coaxially fixed to the hinge shaft 2100 of the air deflector 2121. At least one side of each air deflector 2121 is correspondingly provided with a gear 2005, and in addition, a rack 2006 is provided. The rack 2006 is in gear engagement with the gears 2005 on the same side of all the air deflectors 2121 at the same time. Therefore, by driving the rack 2006 to move, the gears 2005 engaged therewith can be driven to rotate at the same time, thereby driving the rotation of the hinge shaft 2100, and then realizing the adjustment of the angle of the air deflector 2121.

[0058] In addition, the rack 2006 can be driven by a cylinder body, and the cylinder body can be connected to the electronic control module.

[0059] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
