Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, and more particularly to a gas-liquid separation device with a cyclone chamber and a cleaning equipment. BACKGROUND

[0002] The currently used cleaning equipment such as a floor cleaning machine can not only be used for dust collection, but also can spray water and cleaning agent on the surface to be cleaned, and can suck the sewage containing solid waste to take it away from the cleaned surface, integrating the functions of dust and water suction, and having the advantages of environmental protection, energy saving, high efficiency and the like. The cleaning equipment is provided with a gas-liquid separation device, which is mainly used for collecting and storing the sewage and solid waste generated after cleaning. After use, a large amount of sewage and dirt need to be manually cleaned, which increases the burden of the user. Some gas-liquid separation devices are provided with a filter component inside, which separates the solid waste from the sewage through the filter component, avoiding the user's manual cleaning of the water tank assembly, thereby improving the user's experience. However, the ordinary filter component can only realize solid-liquid separation, and cannot effectively realize gas-liquid separation, so as to ensure that the gas is smoothly discharged and the liquid and solid waste are retained. For example, a Chinese patent with the publication number CN102018474B discloses a suction cleaning equipment and a centrifugal separator. The suction cleaning equipment includes a mixture conveying system and a mixture recovery system. The mixture recovery system includes a centrifugal separator for separating a working air flow carrying liquid and debris. The centrifugal separator has a tangential air / water inlet, a water outlet and an air outlet in the lower part. The air outlet has a vertical standpipe extending upward from the tangential air / water inlet and the water outlet. In the technical solution, the working air flow carrying liquid and debris is sucked into the separator through the tangential air / water inlet for separation. Although the liquid, foam and debris carried by the working air flow can be separated, a large amount of liquid and debris enter the separator together, which can easily cause a large amount of liquid to be directly blown out of the separator during the centrifugal separation process, thereby affecting the actual separation efficiency.

[0027] A cyclone column 2 is arranged at the center of the cyclone chamber 122, the cyclone chamber 122 is provided with a tangential first inlet 124, the fluid containing solid first passes through the filter cavity 121 to separate the solid from the fluid, the solid is left in the filter cavity 121, and the fluid is discharged from the filter cavity 121 to the containing cavity 11 through the first outlet 123, the fluid in the containing cavity 11 is automatically gas-liquid separated under the action of gravity, most of the liquid is left in the containing cavity 11, and the fluid containing a small amount of liquid enters the cyclone chamber 122 through the first inlet 124, the tangential first inlet 124 and the cyclone column 2 can form a cyclone effect in the cyclone chamber 122, so that the gas and the liquid are efficiently separated therein, the tangential inlet design enables the fluid to enter the cyclone chamber 122 in a high-speed rotating manner, the centrifugal force pushes the heavier liquid and dust to the cavity wall, and the lighter gas is concentrated to the center, realizing efficient separation, the secondary separation through the cyclone chamber 122 greatly improves the separation efficiency of the gas-liquid separation device 1.

[0028] More specifically, as shown in Figure 2 The first filter element is installed on the cyclone column 2 and communicated with the gas outlet of the gas-liquid separation device 1, the first filter element is used for filtering the fluid in the cyclone chamber 122 to discharge the gas, the first filter element is installed on the cyclone column 2 and can directly contact and treat the fluid after cyclone separation, further ensuring that only the gas can pass through the first filter element, and the liquid and solid particles can be intercepted in the cyclone chamber 122, thereby further improving the separation efficiency.

[0029] More specifically, as shown in Figure 2 and Figure 3 , the first inlet 124 is arranged on the side wall of the cyclone cavity 122, and the first filter is arranged at the center of the cyclone cavity 122. The tangential arrangement of the first inlet 124 helps to form a cyclone effect. When the fluid enters the cyclone cavity 122 through the first inlet 124 on the side wall, it will start to rotate due to the tangential arrangement of the first inlet 124, thereby forming a cyclone to achieve separation. The first filter is arranged at the center of the cyclone cavity 122, so that the first filter is located in the central region of the cyclone, that is, the place where the gas finally collects, which helps to concentrate the gas separated from the cyclone and improve the separation efficiency.

[0030] More specifically, as shown in Figure 2 , the second filter 3 is installed at the exhaust port of the gas-liquid separation device 1, and the second filter 3 is located above the first filter. The gas sequentially passes through the first filter and the second filter 3 to be discharged through the exhaust port of the gas-liquid separation device 1.

[0031] More specifically, as shown in Figure 4 and Figure 5 , the top of the cyclone column 2 is provided with an extension seat 21, and the extension seat 21 is connected with the top of the cyclone cavity 122 in an upper and lower sleeving manner. The extension seat 21 is arranged on the cyclone column 2 and is installed on the top of the cyclone cavity 122 to fix the cyclone column 2, so that the installation of the cyclone column 2 is simple and reliable. The second filter 3 is installed on the extension seat 21, and the extension seat 21 can also be used to install the second filter 3, so that the installation of the second filter 3 is simple and reliable.

[0032] More specifically, as shown in Figure 4 and Figure 5 , the extension seat 21 is provided with a mounting groove 211 matched with the top of the cyclone cavity 122, and the extension seat 21 is connected with the top of the cyclone cavity 122 through the mounting groove 211.

The extension seat 21 is arranged through the mounting groove 211 to be connected with the top of the cyclone cavity 122 in an upper and lower sleeving manner, which is simple and reliable in structure and labor-saving in installation.As shown, the first filter is a metal filter screen, and the second filter 3 is a filter sponge. The first filter is preferably a metal filter screen, which has a fixed pore size and can block larger solid impurities while allowing gas to pass through. The second filter 3 is preferably a filter sponge, which has high porosity and softness and can capture finer particles and liquids. The gas separated by the cyclone is preliminarily filtered by the metal filter screen, which intercepts the liquid and larger solid impurities in the gas in the cyclone cavity 122. The gas filtered preliminarily is secondarily filtered by the filter sponge, which intercepts the finer particles and liquids in the gas, thereby improving the filtering efficiency.

[0034] More specifically, as shown in Figure 2 and Figure 3 , the cyclone cavity 122 is arranged above the filter cavity 121, and the cyclone cavity 122 is located directly above the filter cavity 121.

[0035] More specifically, as shown in Figure 2 and Figure 3 , the outer wall of the separation barrel 12 is provided with a wind channel guide plate 125, which is engaged with the inner wall of the containing cavity 11. The wind channel guide plate 125 is located between the first outlet 123 and the first inlet 124 to separate the first outlet 123 and the first inlet 124. The wind channel guide plate 125 separates the first inlet 124 and the first outlet 123 vertically, so that the fluid discharged from the first outlet 123 is blocked by the wind channel guide plate 125 and cannot flow directly upward to the first inlet 124. The wind channel guide plate 125 is used to guide the fluid discharged from the first outlet 123 to flow to the first inlet 124. Under the action of the guide plate, the flow path of the fluid is longer, which is more conducive to gas-liquid separation. The wind channel guide plate 125 separates the fluid by gas-liquid separation, without the need for additional mechanical components or energy consumption, simplifying the separation process.
