Description

Technical Field

[0001] This utility model belongs to the field of bamboo basket production technology, specifically relating to an adsorption cooling device. Background Technology

[0002] During the production of bamboo baskets, they need to be dried first, and then cooled to achieve the shaping process.

[0003] Currently, the cooling of bamboo baskets is generally carried out by a breathable mesh conveyor belt connected to the outlet of the drying equipment. This conveyor belt usually uses a metal woven chain mesh as the conveyor belt to transport the bamboo baskets. Then, fans set at intervals on the top of the conveyor belt blow air onto the bamboo baskets to cool and shape them.

[0004] However, the inventors discovered that the aforementioned prior art still has several problems:

[0005] 1. The fan is set at the top of the conveyor belt to blow air, but the airflow generated is difficult to penetrate the inside of the bamboo basket, resulting in poor cooling uniformity;

[0006] 2. Because the drying temperature of bamboo baskets is not high, generally between 50℃ and 70℃, in summer, due to the high ambient temperature and the small temperature difference between the dried bamboo basket and the ambient temperature, the cooling speed of the bamboo basket is slow. In winter, due to the low ambient temperature and the large temperature difference between the dried bamboo basket and the ambient temperature, the cooling speed of the bamboo basket is faster, which leads to an imbalance of internal stress in the bamboo material, making it prone to quality problems such as cracking.

[0007] In view of this, the present invention provides an adsorption-type cooling device to solve the above problems. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: an adsorption cooling device, comprising:

[0009] A breathable mesh belt conveyor unit is used for conveying materials;

[0010] A fan unit is located below the breathable mesh belt conveyor unit and is used to generate airflow that penetrates the breathable mesh belt conveyor unit from top to bottom.

[0011] A support unit is disposed above the breathable mesh belt conveyor unit; and

[0012] At least one heat exchange unit is disposed on the support unit and extends meanderingly along the conveying direction of the breathable mesh belt conveyor unit, for exchanging heat with the airflow generated by the fan unit, so that the airflow can penetrate the breathable mesh belt conveyor unit after being heated or cooled.

[0013] As a preferred embodiment of the adsorption cooling device of this utility model, the fan unit includes a frame and at least one set of impeller fans installed on the frame.

[0014] As a preferred embodiment of the adsorption cooling device of this utility model, the impeller fan is arranged at intervals along the conveying direction of the breathable mesh belt conveyor unit.

[0015] As a preferred embodiment of the adsorption-type cooling device of this utility model, the support unit includes a support portion that is disposed opposite to the support portion and extends along the conveying direction of the breathable mesh belt conveying unit, a bent portion that is inclinedly connected to the top of the support portion, and a connecting portion that is inclinedly connected between the bent portions to form an enclosure.

[0016] As a preferred embodiment of the adsorption cooling device of this utility model, the surface of the bent portion is provided with a first positioning hole for the heat exchange unit to pass through.

[0017] In a preferred embodiment of the adsorption-type cooling device of this utility model, the inclined direction of the bending portion and the connecting portion faces the outside of the breathable mesh belt conveyor unit.

[0018] As a preferred embodiment of the adsorption cooling device of this utility model, the heat exchange unit includes a pipe body and a medium inlet and a medium outlet located at both ends of the pipe body.

[0019] As a preferred embodiment of the adsorption-type cooling device of this utility model, the bottom of the main body of the pipe is covered with a circulating water absorption component.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model adopts a bottom-mounted fan unit, which allows airflow to penetrate the breathable mesh belt conveyor unit from top to bottom under the condition of exhaust negative pressure, thereby allowing the airflow to better penetrate the inside of the bamboo basket and uniformly cool the bamboo basket.

[0022] 2. This utility model uses a heat exchange unit set above the breathable mesh belt conveyor unit. After the fan unit generates airflow from top to bottom, heat exchange is achieved through the heat exchange between the airflow and the heat exchange unit to cool the bamboo basket steadily. This slowly releases the stress in the bamboo and reduces the occurrence of quality problems such as cracking of the bamboo basket. Attached Figure Description

[0030] 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.

[0031] This utility model relates to an adsorption-type cooling device, such as... Figures 1-2 As shown, it includes a breathable mesh belt conveyor unit 1 connected at one end to the outlet of the drying equipment for conveying materials, a fan unit 2 disposed below the breathable mesh belt conveyor unit 1, a support unit 3 disposed above the breathable mesh belt conveyor unit 1, and at least one set of heat exchange units 4 disposed on the support unit 3 and extending meanderingly along the conveying direction of the breathable mesh belt conveyor unit 1.

[0032] Among them, such as Figure 2 As shown, the fan unit 2 includes a frame that is fastened to the four legs of the breathable mesh belt conveyor unit 1 by fasteners such as bolts, and at least one set of impeller fans mounted on the frame. The impeller fans can be, for example, axial flow fans or exhaust fans, and multiple sets can be installed at intervals according to the conveying length of the breathable mesh belt conveyor unit 1. When material is conveyed on the breathable mesh belt conveyor unit 1, the airflow generated by the impeller fans flows from top to bottom, effectively allowing the airflow to pass through the inside of the dried bamboo basket for effective cooling.

[0033] like Figure 3As shown, the support unit 3 includes a support portion 31 that is arranged opposite to each other and extends along the conveying direction of the breathable mesh belt conveyor unit 1, a bent portion 32 that is inclinedly connected to the top of the support portion 31, and a connecting portion 33 that is inclinedly connected between the bent portions 32 to form an enclosure. The bent portions 32 and the connecting portion 33 are inclined towards the outside of the breathable mesh belt conveyor unit 1 to form a trapezoidal opening, so as to form a more concentrated airflow path at the opening and facilitate the introduction of airflow. The support portion 31 is square plate-shaped and is located on both sides of the breathable mesh belt conveyor unit 1 to guide the conveyed material. The openings formed at both ends of the support portion 31 can be blocked by baffles to achieve heat insulation from the outside, similar to door curtains or lead curtains at the entrances and exits of security inspection equipment.

[0034] Furthermore, the surface of the bending portion 32 is provided with a first positioning hole 321 for the heat exchange unit 4 to pass through. Multiple sets of the first positioning holes 321 are opened at intervals along the extension direction of the bending portion 32. The heat exchange unit 4 meanders through the multiple sets of first positioning holes 321. Through the meandering of the heat exchange unit 4, the residence time of the medium can be extended, ensuring sufficient heat exchange with the airflow.

[0035] Specifically, such as Figure 4 As shown, the heat exchange unit 4 includes a pipe body 41, preferably made of a material with high thermal conductivity, such as copper, and a medium inlet 42 and a medium outlet 43 located at opposite ends of the pipe body 41. The medium inlet 42 and the medium outlet 43 are respectively connected to the medium circulation outlet pipe and inlet pipe of an external temperature control device. In this embodiment, the temperature control device can be a type such as the one described in announcement number CN116266062B. This temperature control device uses a water circulation mechanism. Through its internal refrigeration circulation mechanism and heater, it can heat or cool the internal water, and then circulate the water into the heat exchange unit 4 after it has been fed into the heat exchange unit 4. The specific principle will not be elaborated here.

[0036] The following explanation uses the production of bamboo baskets as an example:

[0037] Connect one end of the breathable mesh belt conveyor unit 1 to the outlet end of the bamboo basket drying equipment. When the bamboo basket is sent out of the drying equipment, it can be placed on the breathable mesh belt conveyor unit 1 for conveying. Start the fan unit 2 to run, so that the fan unit 2 generates an airflow that penetrates the breathable mesh belt conveyor unit 1 from top to bottom.

[0038] In summer, due to the high ambient temperature, the water flowing inside the heat exchange unit 4 can be cooled by the refrigeration cycle mechanism of the temperature control equipment. When the airflow passes through the heat exchange unit 4, the heat transfer between the airflow and the main body of the pipe 41 is achieved, which reduces the temperature of the airflow before it penetrates the bamboo basket being transported. This can effectively improve the cooling speed of the bamboo basket and thus improve production efficiency.

[0039] In winter, due to the low ambient temperature, the water flowing inside the heat exchange unit 4 can be heated by the heater of the temperature control equipment. When the airflow passes through the heat exchange unit 4, it achieves heat exchange with the airflow through the heat transfer of the pipe body 41, so that the airflow temperature rises before penetrating the bamboo basket being transported. This can effectively slow down the cooling rate of the bamboo basket, achieve slow cooling of the bamboo basket so that it can slowly release internal stress, reduce problems such as cracking of the bamboo basket, and improve the quality of the bamboo basket leaving the factory.

[0040] Furthermore, since the surface of the pipe body 41 may liquefy, causing dripping onto the bamboo basket surface, a circulating water-absorbing component 5 is installed at the bottom of the pipe body 41. The circulating water-absorbing component 5 is made of a water-storing but not water-locking material, such as sponge or sisal fiber felt. The liquefied water on the surface of the pipe body 41 can be absorbed by the circulating water-absorbing component 5 to prevent dripping, while the water stored inside the circulating water-absorbing component 5 is naturally evaporated and drained for reuse.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
