Detailed Description

Referring to fig. 1 and 2, the cooling tank 6 and the aeration tank 12 of the composite cooling device form a left-right structure, which is generally referred to as an upper assembly. An upper assembly and a lower cooling pool 11 form an upper-lower structure.

In general, in the construction shown in fig. 1-3, the upper assembly and the lower cooling tank 11 are of a strip-like construction, noting that the upper cooling tank 6 is located on a first side and the aeration tank 12 is located on a second side of the assembly, and accordingly the upper assembly has a first end and a second end defined in this reference frame, the first end being clearly opposite the second end.

As can be seen from fig. 1 and 2, the rack 2 of the compound cooling device in the figures is the same as the rack of the conventional cooling pool, and the cooling pool is installed at the designed height to adapt to the working condition of the workshop, which belongs to the conventional design in the field and is not described again here.

As can be seen in fig. 3, the composite cooling device is a structure with a relatively large aspect ratio in a top view, and may be defined by the first end and the second end, where the left end is the first end and the right end is the second end.

The upper cooling tank 6 and the aeration tank 12 are connected in the left-right direction in the figures 1-3, wherein the upper cooling tank 6 is arranged on the left side, and the aeration tank 12 is arranged on the right side.

The configuration shown in fig. 1 to 3 is a basic configuration, and in some embodiments, the upper cooling tank 6 may be higher than the aeration tank 12, the entire cooling fluid in the upper cooling tank 6 may be introduced into the aeration tank 12 by gravity-based gravity flow, and since cooling of the work is performed in the upper cooling tank 6, the aeration tank 12 is located slightly lower and does not affect cooling of the work.

When the self-flowing mode is adopted, the upper cooling tank 6 and the aeration tank 12 can be connected through a pipeline with a valve or a partition plate, and the partition plate is provided with a gate valve. The coolant can be automatically flowed to the aeration tank 12 through a valve or a gate valve.

In the structure shown in fig. 1 and 2, the height of the aeration tank 12 is approximately the same as that of the upper cooling tank 6, and in this condition, the coolant in the upper cooling tank 6 cannot flow into the aeration tank 12 by itself, and a special water pumping device is required to pump the coolant in the upper cooling tank 6 into the aeration tank 12.

It should be noted that the cooling tank used in a factory is generally provided with an independent cooling system, and the cooling tank has a relatively long period of time when the temperature rises to a set high value due to cooling of the workpiece. In other words, according to the embodiment of the present invention, the coolant in the aeration tank 12 is replaced by replacing the coolant, and in the coolant replacement cycle of the upper cooling tank 6, the coolant in the aeration tank 12 can completely make the coolant in the aeration tank reach the usable state of the upper cooling tank 6 based on natural cooling. In the embodiment of the present invention, the coolant cooled by the aeration tank 12 is not directly introduced into the upper cooling tank 6, but is introduced into the lower cooling tank, so that the coolant is changed based on the triangular relationship, instead of being changed one by one, and the lower cooling tank 11 corresponds to a relay tank during the change.

The aeration tank 12 has a plurality of aeration heads 17 attached to the bottom thereof. The coolant initially introduced from the upper cooling pond 6 into the aeration tank 12 has a high temperature, but the coolant can be used as much as possible without affecting the effect of aeration and dust removal, rather than simply cooling the coolant naturally.

For the lower cooling pool 11, which is installed at the bottom of the frame 2, the center of gravity of the composite cooling device can be greatly lowered, and therefore, the stability is relatively good. Further, the volume of the lower cooling pool 11 is required to be equal to or greater than twice the volume of the upper cooling pool 6. In the structure shown in fig. 1-3, an air cooling device, i.e. a fan unit 8 shown in the figure, is also provided for slow cooling, in such applications, the cooling liquid can be partially guided into a lower cooling tank 11 and partially contained in an aeration tank 12, and an upper cooling tank 6 forms a dry tank, and a rack is used for carrying workpieces, so as to perform slow cooling by using the fan unit 8. In this way, the complexity of the cooling device can be further improved.

Correspondingly, the lower cooling tank 11 is internally provided with a heat exchange part, the inner fluid (hot fluid) of the heat exchange part is gas, the outer fluid (cold fluid) of the heat exchange part is cooling liquid, and the lower cooling tank 11 is of a groove type structure, so that the heat exchangers are relatively more applicable, such as cooling pipelines, cooling inner containers or heat dissipation plates, and the heat exchangers are internally provided with the fluid to be cooled, such as gas, and are arranged in the lower cooling tank 11 and immersed in the cooling liquid.

As described above, since the period in which the coolant needs to be replaced depending on the temperature is relatively long, the coolant has a sufficient time to cool after being introduced from the upper cooling tank 6 into the aeration tank 12, and when the upper coolant 6 has a high temperature and needs to be replaced again, the coolant in the aeration tank 12 is introduced into the lower cooling tank 11, the coolant in the upper cooling tank 6 is further introduced into the aeration tank 12, and the liquid in the lower cooling tank is partially introduced into the upper cooling tank 6.

Because the embodiment of the present invention has various usage modes, the aeration tank 12 can accommodate the amount of the cooling liquid introduced from the upper cooling tank 6 under the original condition of storing the cooling liquid.

In addition, if there is no coolant in the aeration tank 12 at this time, the volume requirement for the aeration tank 12 to be adapted is low. The above are all simple calculations in the field, and are not described herein again.

Correspondingly, the heat exchanger is communicated with the aeration head 17 to carry out aeration, reduce the dust content in the gas and then discharge the gas.

In the structure shown in fig. 2, a flow guide pipe 15 is arranged between the lower cooling tank 11 and the aeration tank 12, and a valve is arranged on the flow guide pipe 15; a second water pumping device is arranged between the lower cooling pool 11 and the upper cooling pool 6.

In the structure shown in fig. 1, the lower cooling tank 11 and the upper cooling tank 6 are horizontally displaced from each other below the upper assembly, and the lower cooling tank 11 is located below the aeration tank 12, thereby reducing thermal crosstalk of the lower cooling tank 11.

Furthermore, it should be understood that cooling of the gas does not necessarily need to be performed in real time.

In the configuration shown in fig. 2, the draft tube 15 is offset at the second end of the aeration tank 12.

Further, the lower cooling tank 11 is provided with a plurality of filter plates 13 from the second end to the first end to divide the lower cooling tank 11 into a plurality of small tanks which are sequentially guided by the filter plates 13, so that the cooling liquid can be filtered. Accordingly, the small reservoir at the first end is the source reservoir of the second pumping device to ensure relative cleanliness of the fluid pumped into the upper cooling reservoir 6.

For the heat exchanger, as mentioned above, the gas to be cooled belongs to the hot fluid in the heat exchange device, and therefore, the heat exchanger is vertically arranged in the middle of the lower cooling tank 11, so as to adapt to the heat convection.

In the configuration shown in fig. 1, a guide rail 7 is provided on the upper assembly from a first end to a second end. Correspondingly, a sliding seat which is matched with the guide rail 7 to form a guide rail pair is provided, an air cooling device, such as a fan unit 8 shown in fig. 1, is arranged on the sliding seat, when air cooling is needed, the fan unit 8 is firstly pushed to the side of the aeration tank 12, a workpiece to be cooled is placed on a storage rack in the upper cooling tank 6, then the fan unit 8 is reset to the upper part of the upper cooling tank 6, and the workpiece is cooled by the fan unit 8.

For the gas to be purified by aeration, it generally has a certain initial pressure, for example, the gas discharged from an engine, which can reach a pressure above several atmospheric pressures, and can fully meet the aeration requirement. However, there is also a case where the air supply pressure is insufficient, and for this purpose, an aeration fan is provided to the aeration head 12, an inlet of the aeration fan is connected to the air outlet end, and an outlet of the aeration fan is connected to the aeration head 12, so that aeration is performed in an incremental manner.

As described above, since the center of gravity of the hybrid cooling device is moved downward by the lower cooling pool 11, the stability of the whole device is improved, and in this condition, the caster 1 is provided to the frame 2, and the hybrid cooling device can be moved by the caster 1.

The caster 1 may be provided with a locking device, which is a common technical means in the field of caster technology and will not be described herein.

In some embodiments, the bottom of the aeration tank 12 is an inclined bottom with a high first end and a low second end, so as to facilitate the implementation of the self-flowing mode for leading out the cooling liquid.

In the configuration shown in fig. 1, the pump unit 9 is located at the right end, i.e. the first end, of the lower cooling tank 11, and the pump unit is relatively heavy, which is beneficial for reconstructing the position of the center of gravity, and the pump units are adapted to be the first water pumping device and the second water pumping device.
