Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Example 1

As shown in fig. 1 to 3, an ink separation and filtration device for an ink jet printer comprises a main body 1 and a filter housing 2, wherein a mounting bracket 3 is arranged at the top of the main body 1. The main body 1 is provided with a first chamber 101 with an opening at the bottom, a second chamber 102 with an opening at the bottom is arranged in the first chamber 101, and an annular gap is arranged between the first chamber 101 and the second chamber 102. An air inlet joint 4 communicated with the second chamber 102 and an air outlet joint 5 communicated with the first chamber 101 are respectively arranged at two sides of the main body 1.

The filter housing 2 is a white nylon cover that is threaded with the body 1 and communicates with the first chamber 101 through an annular screw cap 6. The joint of the main body 1 and the filter shell 2 is provided with a first sealing ring 7 to ensure the tightness. The filter shell 2 is internally provided with a filter assembly which is detachably connected with the main body 1.

The filtering component comprises a filter element 8 and a filter separator 9 sleeved outside the filter element 8, the filter element 8 is a multi-layer nested cylindrical integrated structure, the outmost layer is a wire mesh, the wall surface of the inner layer is provided with staggered bee holes 801, and the outer layer of the filter element 8 and the inner wall of the filter separator 9 are provided with gaps. A connecting tooth hole 103 is formed in the second chamber 102, and the filter element 8 is in threaded connection with the connecting tooth hole 103 through a filter element screw rod 10 and a nut 11. A second sealing ring 12 is arranged at the joint of the bottom surface of the second chamber 102 and the filter element 8.

The filter partition 9 is cylindrical, the bottom end of the filter partition is open, multiple layers of partition ear strips 901 are arranged on the periphery of the filter partition, a plurality of circular hole collections 902 are arranged on the partition ear strips 901, and the circular hole collections 902 of adjacent layers are arranged in a vertically staggered mode. The outer edge of the ear isolating strip 901 is tightly attached to the inner wall of the filter housing 2. The bottom of the filter shell 2 is provided with a water discharge joint 13, and the water discharge joint 13 is provided with a water discharge valve 14.

The working principle of the utility model is as follows: the air inlet joint 4 is connected with an ink suction head, the air outlet joint 5 is connected with a negative pressure source, and when the air-conditioning filter works, under the action of negative pressure suction force, ink liquid enters from the air inlet joint 4, passes through the second chamber 102, then downwards enters the filter element 8 due to the blocking of the inner wall of the second chamber, and then outwards diffuses from the center of the filter element 8 through the bee holes 801 to perform first heavy gas-liquid separation; the gas-liquid continues moving and collides with the inner wall of the filter partition 9, and at the moment, the liquid is accumulated on the inner wall of the filter partition 9 and subjected to baffling and gravity settling, so that secondary gas-liquid separation is formed; because the outer edges of the lug separating strips 901 are tightly attached to the inner wall of the filter shell 2, the gas and liquid coming next can only pass through the circular hole sets 902 on the lug separating strips 901 to shuttle upwards, and because the circular hole sets 902 are mutually blocked in a vertically staggered manner, the gas flow is subjected to baffling and gravity settling again to form third gas and liquid separation; finally, the separated gas flows out from the gas outlet joint 5.

Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
