Description

Technical Field

[0001] This utility model relates to the field of cold storage preservation technology, specifically a cold storage preservation device. Background Technology

[0002] A cold storage facility is a type of refrigeration equipment. It refers to an environment created artificially to differ in temperature and humidity from the outside world. It is used for the constant temperature and humidity storage of items such as food, liquids, chemicals, pharmaceuticals, vaccines, and scientific research materials. For long-term product storage, cold storage facilities typically use pallets to hold the products.

[0003] Because products are typically stacked vertically on pallets, the pressure between the lower products is relatively high, resulting in a high stacking density. This leads to insufficient ventilation space for products stored on conventional pallets, which is detrimental to preservation. To address this issue, we propose a cold storage preservation device. Utility Model Content

[0004] The purpose of this invention is to provide a cold storage preservation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold storage preservation device, comprising:

[0006] The base has two side plates fixedly welded to its top wall. Multiple slots are provided on the opposite side walls of each side plate, with the slots evenly spaced. Multiple trays are positioned between the two side plates, with each tray's two ends movably inserted into a slot in one of the side plates. A top rod is fixedly welded to the top of each side plate, and a mounting base is mounted on the top rod. A fan is fixedly mounted on the top wall of the mounting base, with an air inlet pipe and an air outlet pipe installed on the fan. A blower base is fixedly mounted on the bottom wall of the mounting base, with multiple evenly spaced blow nozzles fixedly mounted on the bottom wall of the blower base. A guide tube is fixedly mounted on the air outlet pipe, with the end of the guide tube furthest from the air outlet pipe fixedly mounted on the blower base.

[0007] Preferably, the push rod has a through groove, in which a reciprocating lead screw is rotatably mounted. A drive motor is fixedly mounted at one end of the push rod, and the output end of the drive motor is connected to the reciprocating lead screw. The mounting seat is slidably connected in the through groove and is threadedly connected to the reciprocating lead screw through a threaded hole.

[0008] Preferably, the tray has a placement groove, in which a tray plate is fixedly installed, and the tray plate is hollowed out.

[0009] Preferably, multiple rollers are fixedly installed on the bottom wall of the base.

[0010] Preferably, the front end of the slot has a trapezoidal groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When using this utility model, the products that need to be preserved are placed on the perforated tray. During long-term storage, cold air from the cold storage can be drawn in through the air inlet pipe by a fan and blown into the blower base through the exhaust pipe and duct. The air is then blown onto the tray below through multiple blower nozzles. The drive motor drives the mounting base to move back and forth, which in turn drives the multiple blower nozzles to move back and forth, so that the cold air from the cold storage can be kept blowing onto the products on the tray, improving the air flow of the products stored in the cold storage and improving the preservation effect.

[0013] 2. The tray of this utility model can be adjusted to be inserted into the two side plates according to the size of the product placed on it, so as to facilitate the adjustment of the spacing between the trays. This makes the device easy to apply to the preservation and storage of products of various sizes, greatly improving the applicability of the device. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3This utility model provides a technical solution: a cold storage preservation device, comprising:

[0020] The base 1 has two side plates 2 fixedly welded to its top wall. Multiple slots 3 are provided on the opposite side walls of the two side plates 2, and these slots 3 are equidistantly distributed. Multiple trays 4 are positioned between the two side plates 2, with both ends of each tray 4 movably inserted into the slots 3 of the two side plates 2. Top rods 5 are fixedly welded to the top of the two side plates 2, and mounting seats 6 are provided on the top rods 5. A fan 7 is fixedly mounted on the top wall of the mounting seat 6, with an air inlet pipe 8 and an exhaust pipe 9 fixedly mounted on the fan 7. A blower seat 10 is fixedly mounted on the bottom wall of the mounting seat 6, with multiple equidistantly distributed blow nozzles 11 fixedly mounted on the bottom wall of the blower seat 10. A conduit 12 is fixedly mounted on the exhaust pipe 9, with the end of the conduit 12 furthest from the exhaust pipe 9 fixedly mounted on the blower seat 10.

[0021] The top rod 5 has a through groove 13, in which a reciprocating lead screw 14 is rotatably installed. A drive motor 15 is fixedly installed at one end of the top rod 5, and the output end of the drive motor 15 is connected to the reciprocating lead screw 14. The mounting seat 6 is slidably connected in the through groove 13 and is threadedly connected to the reciprocating lead screw 14 through a threaded hole. After the drive motor 15 is started, it can drive the reciprocating lead screw 14 to rotate. During the rotation of the reciprocating lead screw 14, it can drive the mounting seat 6 to move back and forth in the through groove 13, thereby driving the blower seat 10 and multiple blower nozzles 11 to move back and forth to blow air.

[0022] The tray 4 has a placement groove 16, and a tray plate 17 is fixedly installed in the placement groove 16. The tray plate 17 is hollowed out, which facilitates ventilation of the products placed on the tray 4.

[0023] Multiple rollers 18 are fixedly installed on the bottom wall of the base 1. The rollers 18 facilitate the movement of the base 1, thereby facilitating the movement of the device.

[0024] The front end of the slot 3 is provided with a trapezoidal groove 19, which can increase the opening size of the front end of the slot 3, thereby facilitating the insertion of the tray 4 into the slot 3.

[0025] Working principle: When using this utility model, the products that need to be preserved are placed on the hollowed-out tray 17 of the tray 4. During long-term storage, cold air from the cold storage is drawn in through the air inlet pipe 8 by the fan 7 and blown into the blower base 10 through the exhaust pipe 9 and the duct 12. The air is then blown onto the tray 4 below through multiple blower nozzles 11. The drive motor 15 drives the mounting base 6 to move back and forth, which in turn drives the multiple blower nozzles 11 to move back and forth, so that the cold air from the cold storage can be kept blowing onto the products on the tray 4, improving the air flow of the products stored in the cold storage and improving the preservation effect. The position of the tray 4 inserted into the two side plates 2 can be adjusted according to the size of the products placed on it, so as to facilitate the adjustment of the spacing between the trays 4. This makes the device easy to apply to the preservation and storage of products of various sizes, greatly improving the applicability of the device.
