[0018] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] Please refer to Figure 1 and Figure 2 A vacuum filter tank 100 that is easy to clean includes: a tank body 1, an arc-shaped partition plate 2, a cylindrical baffle 3, an air inlet pipe 4, a filter element 5, an air outlet pipe 6 and a waste pipe 7.

[0021] The tank body 1 is cylindrical with upper and lower sealed ends.

[0022] The arc-shaped partition plate 2 is funnel-shaped with a larger top and a smaller bottom. The top of the arc-shaped partition plate 2 is sealed in the tank body 1 to separate the tank body 1 into an upper chamber 11 and a lower chamber 12 .

[0023] The cylindrical baffle 3 is connected to the bottom of the arc-shaped partition plate 2 and is used to connect the upper chamber 11 and the lower chamber 12.

[0024] An air inlet pipe 4 is inserted and connected to the lower chamber 12. The opening of the air inlet pipe 4 is aligned with the outer wall of the arc-shaped partition plate 2, and is used to pass the gas toward the outer wall of the arc-shaped partition plate 2 and then rotate. Since the outer wall of the arc-shaped partition plate 2 is annular, it is easy for the gas to rotate along the outer wall of the arc-shaped partition plate 2, thereby separating impurities.

[0025] The filter element 5 is fixed in the upper cavity 11 .

[0026] The air outlet pipe 6 is inserted into the upper cavity 11 and communicated with the interior of the filter element 5 for discharging the gas filtered by the filter element 5 to subsequent equipment. An openable and closable purge port 61 is provided at one end of the air outlet pipe 6 located outside the tank body 1 .

[0027] The upper end of the waste pipe 7 is inserted into the bottom of the tank body 1 and the lower end of the waste pipe 7 is provided with a sewage valve 71.

[0028] Optionally, the air inlet pipe 4 does not pass through the cylindrical baffle 3 when extending in the axial direction. In this way, the incoming gas can basically rotate along the single-side air inlet, effectively reducing the diversion rotation to both sides and preventing mutual interference.

[0029] Optionally, the lowest point A of the inlet pipe 4 is higher than the bottom surface of the cylindrical baffle 3. This can effectively ensure that the gas entering from the inlet pipe rotates, thereby improving the separation effect.

[0030] Optionally, the air inlet pipe 4 is inserted tangentially to communicate with the tank body 1. This arrangement facilitates guiding the gas entering the tank body 1 to rotate along the inner wall of the tank body 1 to achieve gas-liquid separation.

[0031] Optionally, the axial centerline of the cylindrical baffle 3 and the axial centerline of the arc-shaped partition plate 2 coincide with the axial centerline of the tank body 1. This arrangement provides a better effect of the rotational separation of the gas.

[0032] Optionally, the tank body 1 is further provided with a pressure gauge port 13 for connecting a pressure gauge, so as to facilitate real-time understanding of the air pressure condition in the tank body 1.

[0033] Optionally, the tank body 1 is further provided with an observation port 14, the height of which is lower than the height of the air inlet pipe 4. This makes it easy to observe the waste liquid capacity and discharge the waste in time.

[0034] Optionally, the air outlet pipe 6 is tangentially inserted and connected to the tank body 1. This makes it easy to connect with the filter element 5 and allows the gas inhaled during cleaning to directly flush the filter element 5.

[0035] Optionally, the bottom of the tank body 1 is convex downwards in a funnel shape, so that the waste liquid can be discharged from the bottom of the tank body 1 into the waste pipe 7 better.

[0036] Preferably, the vacuum filter tank 100 for easy cleaning further comprises three supports 8 evenly distributed at the bottom of the tank body 1. This facilitates the vertical placement of the tank body 1.

[0037] The operating principle of the vacuum filter tank 100 that is easy to clean according to one embodiment of the present invention is as follows:

[0038] During separation and filtration, the gas enters the lower chamber 12 through the air inlet pipe 4, and rotates and moves downward along the outer wall of the arc-shaped partition plate 2, the outer wall of the cylindrical baffle 3 and the inner wall of the tank body 1 under the restrictive action of the arc-shaped partition plate 2, the cylindrical baffle 3 and the tank body 1, thereby realizing gas-liquid separation. The separated liquid is discharged downward through the waste pipe 7 and the sewage valve 71, and the separated gas passes upward through the cylindrical baffle 3 into the upper chamber 11. The gas entering the upper chamber 11 passes through the inside of the filter element 5, and the filter element 5 filters out dust and other solid impurities in the gas, and finally the clean gas is discharged from the outlet pipe 6 to the subsequent equipment.

[0039] When the tank body 1 needs to be cleaned, the purge port 61 is opened. Since the tank body 1 is in a vacuum state during separation and filtration, once the purge port 61 is opened, the gas in the air is instantly sucked into the tank body 1 through the purge port 61, flushing the filter element 5 and the inner wall of the tank body 1. The flushed impurities fall along the inner wall of the curved partition plate 2 and the inner wall of the tank body 1 to the bottom of the tank body 1, and finally the waste liquid is discharged from the drain valve 71. This is convenient to operate and can achieve tank cleaning without opening the tank body 1, greatly improving work efficiency.

[0040] The easy-to-clean vacuum filter tank of the utility model can not only conveniently clean the inside of the tank, but also greatly improve the filtering effect and filtering efficiency of the vacuum filter tank.

[0041] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
