[0025] In this embodiment, a centrifuge with a cooling device is provided, which includes a base and a casing fixedly installed on the base. The casing has a first channel and a second channel. One end of the first channel is provided with a water inlet, and the other end is connected to one end of the second channel through a cooling pipe. The other end of the second channel is provided with a water outlet.

[0026] The casing includes an upper cover 2 and a lower cover 1, and the upper cover 2 and the lower cover 1 are detachably connected up and down.

[0027] The upper cover 2 includes a first inner shell and a first outer shell. The first outer shell is sleeved on the outer periphery of the first inner shell, and a first channel is formed between the first outer shell and the first inner shell. The first outer shell is connected to the bottom of the first inner shell.

[0028] The lower cover 1 includes a second inner shell and a second outer shell. The second outer shell is sleeved on the outer periphery of the second inner shell, and a second channel is formed between the second outer shell and the second inner shell. The second outer shell is connected to the top of the second inner shell.

[0029] Specifically, the stability and firmness of the base are the key to ensuring the normal operation of the centrifuge. Fixing the casing on the base ensures the stability and safety of the equipment during high-speed rotation. The casing includes an upper cover 2 and a lower cover 1. The detachable connection design of the upper cover 2 and the lower cover 1 up and down makes the maintenance and cleaning work more convenient. The detachable connection method also facilitates the inspection and replacement of internal components, improving the maintainability of the equipment. The first channel is the space formed between the first inner shell and the first outer shell. Similarly, the second channel is the space formed between the second inner shell and the second outer shell.

[0030] In an embodiment of the present utility model, the water outlet includes a first water outlet 10 and a second water outlet 6; the water inlet includes a first water inlet 8 and a second water inlet 11. The first water inlet 8 and the first water outlet 10 are respectively arranged on the side wall of the lower housing 1, and the second water inlet 11 and the second water outlet 6 are respectively arranged on the side wall of the upper housing 2. The first water outlet 8 is communicated with the second water inlet 11 through a cooling pipeline 7.

[0031] Furthermore, the cooling pipeline 7 is placed outside the machine housing.

[0032] Meanwhile, the first water inlet 8 and the first water outlet 10 are provided on the side wall of the lower housing 1, and the second water inlet 11 and the second water outlet 6 are provided on the side wall of the upper housing 2. The first water outlet 8 is communicated with the second water inlet 11 through the cooling pipeline 7 to form a closed cooling loop, ensuring that the cooling medium can circulate between the upper and lower housings. Such a design helps to effectively control the temperature during the centrifugation process and ensure that the material is separated within the specified temperature range.

[0033] Furthermore, the first water inlet 8 is arranged at the bottom of the side wall of the lower housing 1, the first water outlet 10 is arranged at the top of the side wall of the lower housing 1, the second water inlet 11 is arranged at the bottom of the side wall of the upper housing 2, and the second water outlet 6 is arranged at the top of the side wall of the upper housing 2.

[0034] Furthermore, the second water inlet 11 and the second water outlet 6 are communicated through the first channel.

[0035] Specifically, the first water inlet 8 is located at the bottom of the side wall of the lower housing 1, while the first water outlet 10 is located at the top of the side wall of the lower housing 1. Such a design helps the cooling medium to flow from bottom to top, effectively covering the entire side of the lower housing 1 and improving the cooling efficiency. Similarly, the second water inlet 11 is located at the bottom of the side wall of the upper housing, and the second water outlet 6 is located at the top of the side wall of the upper housing 2. Such a layout enables the cooling medium to cover the entire side of the upper housing 2.

[0036] Meanwhile, the second water inlet 11 and the second water outlet 6 are communicated through the first channel, allowing the cooling water to flow between the first inner shell and the first outer shell to cool the inside of the upper housing 2. The cooling water enters from the second water inlet 11, flows through the first channel, absorbs the heat inside the upper housing, and then discharges from the second water outlet 6.

[0037] Through this design of the cooling water flow in the upper and lower housings, the temperature inside the entire centrifuge can be effectively controlled, ensuring that the material is separated within the specified temperature range, and improving the separation effect and product quality.

[0038] Further, a cavity is formed between the first inner shell and the second inner shell. A seal 4 is provided at the top of the upper cover shell, and the seal 4 is fixedly connected to the upper cover shell 2.

[0039] Further, a rotating shaft 9 is provided at the bottom of the cavity. The rotating shaft 9 is fixedly connected to the bottom of the drum 3. One end of the top of the drum 3 is connected to the ventricle 5, and the other end of the ventricle 5 extends upward through the seal 4.

[0040] Further, a material tank is provided between the second outer shell and the second inner shell. The second channel surrounds the material tank, and the material tank is symmetrically arranged along the central axis of the casing.

[0041] Specifically, the cavity formed between the first inner shell and the second inner shell is the key space for the centrifuge to perform separation operations. This space is designed to accommodate the material to be separated and perform separation under the action of centrifugal force. The seal 4 at the top of the upper cover shell 2 ensures the sealing of the cavity during high-speed rotation, preventing material leakage and the infiltration of cooling water. The fixed connection between the seal 4 and the upper cover shell 2 improves the overall stability and safety of the equipment. The rotating shaft 9 provided at the bottom of the cavity is fixedly connected to the bottom of the drum 3, enabling the drum 3 to rotate at high speed and generate sufficient centrifugal force for separation. One end of the top of the drum 3 is connected to the ventricle 5, and the other end of the ventricle 5 extends upward and passes through the seal 4. The ventricle 5 utilizes centrifugal force for effective material separation and realizes pressurized discharge. Such a design helps in the separation and collection of materials under the action of centrifugal force. In this embodiment, the seal 4 is a flange, and the flange is fixedly connected to the upper cover shell 2 by bolts.

[0042] The material tank provided between the second outer shell and the second inner shell is used to collect solid waste or sediment generated during the separation process. The second channel surrounds the material tank, and such a layout helps the cooling water to effectively absorb the heat in the area of the material tank during the flow process, preventing the accumulation and blockage of solid materials in the material tank. The material tank is symmetrically arranged along the central axis of the casing, and such a design helps to balance the load of the centrifuge during high-speed rotation, improving the operating stability and separation efficiency of the equipment.

[0043] In a second aspect, the present invention provides a cooling method for a centrifuge with a cooling device. Please refer to Figure 2 , and use a centrifuge with a cooling device as described in any one of the above, including:

[0044] S1. Inject the refrigerant along the water inlet so that the refrigerant flows into and fills the second channel;

[0045] S2. Continue to fill to make the refrigerant fill the first channel;

[0046] S3. Start the centrifuge and open the water outlet to let the refrigerant flow out and maintain the circulation of the refrigerant.

[0047] Specifically, first, inject the cooling medium (such as cooling water or other cooling liquids) into the lower housing through the first water inlet 8. The first water inlet 8 is located at the bottom of the side wall of the lower housing. After the refrigerant enters from the first water inlet 8, it flows along the second channel inside the lower housing. The second channel is the space formed between the second inner shell and the second outer shell. The refrigerant flows in this area and fills the second channel.

[0048] When the second channel is filled with the refrigerant, continue to inject the refrigerant so that it flows into the first channel of the upper housing through the connecting pipe. The first channel is the space formed between the first inner shell and the first outer shell. The refrigerant flows in this area and fills the first channel. After the first channel is filled with the refrigerant, start the centrifuge and open the second water outlet 6. The second water outlet 6 is located at the top of the side wall of the upper housing. After opening the second water outlet 6, the refrigerant begins to flow out and takes away the heat generated during the high-speed rotation of the drum.

[0049] After the refrigerant flows out from the second water outlet 6, it flows back to the liquid storage tank or the cooling device of the cooling system through the externally connected pipe. Then, the refrigerant can be pumped to the first water inlet 8 again to continue the cycle to maintain the temperature control inside the centrifuge.

[0050] To sum up, the centrifuge provided in the present utility model can effectively control the temperature during the operation of the centrifuge, ensure that the material is separated within the specified temperature range, improve the separation effect and the safety and stability of the product. At the same time, this method can also extend the service life of the equipment, reduce energy consumption, and achieve the goal of energy conservation and environmental protection.

[0051] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model belongs, according to the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
