[0035] Please refer to Figure 1 and Figure 2 The present application discloses an oil filtering seat. The oil

[0036] The filter seat comprises a body 1, an oil inlet channel 2, an oil outlet channel 3, and an oil filter channel 4, which is used to connect with an oil filter 7 for filtering the oil agent to remove impurities in the oil agent. The oil filter channel 4 comprises a buffer channel 41 and an oil return channel 42, wherein the buffer channel 41 is in communication with the oil inlet channel 2 and the inlet of the oil filter 7, the outlet of the oil filter 7 is in communication with the oil return channel 42, and the oil return channel 42 is in communication with the oil outlet channel 3. The buffer channel 41 is used to slow down the flow rate of the oil agent to avoid the oil agent directly flowing to the inlet of the oil filter 7 to form accumulation or cause vortex effect. The oil agent flows to the buffer channel 41 after entering the oil inlet channel 2, and then flows to the oil filter 7 after being buffered in the buffer channel 41. The filtered oil agent flows to the oil outlet channel 3 through the oil return channel 42, thereby preventing the oil agent from blocking at the inlet of the oil filter to affect the normal delivery of the oil agent and ensuring the normal operation of the oil equipment.

[0037] As shown in Figure 3 The buffer channel 41 of the present embodiment is in three-step stepped shape and comprises a first channel 411, a second channel 412, and a third channel 413 distributed from top to bottom, wherein the first channel 411 is in communication with the oil inlet channel 2, the third channel 413 is in communication with the inlet of the oil filter 7, and the area of each channel gradually expands, thereby expanding the area in communication with the oil filter 7, diffusing the oil agent, and further improving the accumulation of the oil agent. Specifically, the first channel 411, the second channel 412, and the third channel 413 are concentric and have the same diameter and arc shape, and are coaxial with the oil return channel 42. The arc length of each channel gradually increases from top to bottom. The arc length of the third channel 413 is not more than half of the circumference of the third channel 413, i.e., the arc length of the third channel 413 is not more than half of the circumference of the third channel 413, to avoid the temperature loss of the oil agent due to the excessively long channel.

[0038] In other embodiments, the buffer channel can be gourd-shaped. The top of the gourd-shaped channel is in communication with the oil inlet channel, and the bottom is connected with the inlet of the oil filter. After the oil agent enters the top of the gourd-shaped channel, it gradually diffuses and buffers in the gourd cavity along the wall of the channel, thereby avoiding the accumulation of the oil agent at the inlet of the oil filter.

[0039] Specifically, the oil filter channel 4 can be provided with multiple oil filter channels, and a corresponding number of oil filters can be installed to increase the filtering amount of the oil agent and improve the filtering efficiency. As shown in Figure 4 and Figure 5 In the present embodiment, the oil filter channel 4 is provided with three oil filter channels to increase the filtering amount, and the first channels 411 of the three oil filter channels are in communication with each other through the oil inlet channel 2. The oil filter seat further comprises a converging channel 5, and the three oil return channels 42 are in communication with each other through the converging channel 5. The converging channel 5 is in communication with the oil outlet channel 3, and the filtered oil agent is converged to the converging channel 5 through the oil return channels 42 and then flows to the oil equipment through the oil outlet channel 3. In the present embodiment, the oil outlet channel 3 is provided with two oil outlet channels. In daily use, the ports of the converging channel 5 and other process holes provided on the body can be plugged with plugs to prevent oil leakage.

[0040] Specifically, as shown in Figure 1 The oil filter seat further comprises three detection holes, i.e. a first detection hole 61, a second detection hole 62 and a third detection hole 63. The first detection hole 61 is used to install a first pressure sensor, the second detection hole 62 is used to install a second pressure sensor, and the third detection hole 63 is used to install a temperature sensor. The first pressure sensor is used to detect the pressure in the oil inlet channel 2, the second pressure sensor is used to detect the pressure in the oil return channel 42, and the temperature sensor is used to detect the temperature in the oil return channel 42. The three detection holes are in communication with the corresponding channels. The pressure difference before and after oil filtration is detected by the two pressure sensors to determine the use condition of the oil filter, so that the oil filter can be replaced or cleaned in time. The temperature of the oil after oil filtration is detected by the temperature sensor to timely find out the case of excessively high or low oil temperature, thereby avoiding the influence on the normal operation of the oil equipment.

[0041] As shown in Figure 5 The cooling pipe 51 can be made of a hollow aluminum pipe, a hollow copper pipe or a high-temperature-resistant glass pipe. The refrigeration equipment sends cooling liquid or cooling gas into the hollow interior of the cooling pipe 51 to cool the pipe body, so as to exchange heat with the oil in the channel and achieve the cooling of the oil.

[0042] In this embodiment, the body 1 comprises a first end and a second end in the length direction, and a first side and a second side in the length direction. The first end is connected with the pipeline of the oil conveying pump, and the second side is connected with the oil equipment. The oil inlet channel 2 is arranged at the first end of the body 1, the oil filtration channel 4 is arranged at the bottom of the body 1, the oil inlet channel 2 extends towards the second end, and the first-stage channel 411 extends towards the top until the two channels are communicated. The oil return channel 42 extends towards the top until the oil return channel 42 is communicated with the oil confluence channel 5. The detection hole is arranged at the first side, and the oil outlet channel 3 is arranged at the second side, so as to be directly communicated with the oil passage in the oil equipment.

[0043] Please refer to Figure 6 is a schematic view of the oil filter seat and the oil filter provided in this embodiment. Three oil filters 7 are connected with the three oil filtration channels 4 at the bottom of the body 1. The oil filter 7 comprises a first filter layer and a second filter layer. The first filter layer is provided with a filter core for filtering impurities in the oil, and the first filter layer is in communication with the second filter layer. The top of the first filter layer is the inlet of the oil filter and is communicated with the third-stage channel 413, and the top of the second filter layer is the outlet of the oil filter and is communicated with the oil return channel 42.

[0044] Further, the oil filter seat further comprises a defoaming structure (not shown in the figure) located between the second side of the body 1 and the oil using equipment, and the defoaming structure comprises two defoaming holes in communication with the two oil outlet channels 3. The filtered oil agent can generate part of the foam, and the defoaming holes can prolong the path of the oil agent entering the oil using equipment, facilitate the defoaming treatment, and avoid the influence of the foam on the use effect of the oil agent.
