Detailed Description

The following description will be made in detail with reference to the accompanying drawings and examples. The following examples are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

In the present specification, terms of orientation or positional relationship such as up, down, left, right, inside, outside, front, rear, head, and tail are established based on the orientation or positional relationship shown in the drawings. The corresponding positional relationship may also vary depending on the drawings, and therefore, should not be construed as limiting the scope of protection.

The present invention relates to a portable electronic device, and more particularly, to a portable electronic device, which can be connected to a portable electronic device, and can be connected to a portable electronic device through a connection structure, such as a connector, a. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

This embodiment describes a multifunctional trough for coating machine, as shown in fig. 1, the trough is divided into an overflow area and a return area by an overflow baffle 4 fixed at the bottom of the trough, and the feed liquid is used in the return area of the trough after being cleaned of impurities in the overflow area by a return device 6.

The inlet pipe 1 sets up in silo overflow district bottom one end for to the silo transport feed liquid, from the silo bottom feeding help accelerating the feed liquid in the even mixture tank.

Reflux unit 6 sets up in the silo below, and overflow pipe 7 sets up the other end in the silo overflow area, and its output is worn out the silo bottom and is linked together with reflux unit 6. When the height of the feed liquid exceeds the height of the overflow pipe 7, the feed liquid overflows from the input end at the top of the overflow pipe 7 and flows to the reflux device 6. For increasing the interior charge-liquid capacity of silo, can add overflow extension pipe 2 at overflow pipe 7 top, increase the height of overflow, preferably, overflow extension pipe 2 can be adjusted from top to bottom in the position on overflow pipe 7, realizes the autonomic regulation of overflow pipe overall height, satisfies different overflow demands, if overflow extension pipe 2 passes through threaded connection on overflow pipe 7, reciprocates along overflow pipe 7 through rotatory screw overflow extension pipe 2.

Overflow baffle 4 highly is higher than overflow pipe 7 and the biggest stack height of overflow extension pipe 2, and is less than the height of silo, and when overflow pipe 7 or filter screen 8 took place to block up, overflow baffle 4 was walked over to the feed liquid, gets into reflux unit 6 from back flow 5 and flows back, the phenomenon of splashing that produces when preventing that the overflow from breaking down reduces the pollution to equipment and product.

Simultaneously, for preventing impurity to spill over along with the feed liquid, overflow extension pipe 2 and overflow pipe 7 set up in filtering pipe 3, it fixes in the silo bottom to filter pipe 3, and its top is airtight, the bottom side is equipped with filter screen 8, filter screen 8 can filter the impurity in the feed liquid one step earlier, filter screen 8 cross-sectional area is greater than the 3 cross-sectional areas of filter pipe, its aim at accelerates the filtration to the feed liquid, in order to satisfy the demand that the feed liquid spills over, and great filter screen 8 cross-sectional area can prolong filter screen 8's life cycle, avoid filter screen 8 to be blockked up in the short time, frequently change filter screen 8, overflow extension pipe 2 and filter pipe 3 between have certain interval, so that the feed liquid gets into overflow pipe 7 with certain.

Preferably, filter pipe 3 and silo bottom and pass through the buckle and be connected, conveniently dismantle at any time and filter pipe 3, adjust the overflow height, or the clearance is attached to the impurity on the filter screen.

The return pipe 5 is arranged at the bottom of the trough of the return area, the input end at the bottom of the return pipe is communicated with the output port at the top of the return device 6, and the output end at the top of the return pipe 5 is communicated with the trough. The feed liquid in the reflux device 6 flows back to the reflux area of the feed tank through the reflux pipe 5.

The bottom of the reflux device 6 is provided with an overflow port 9 which is communicated with an output port at the bottom of the reflux device 6, and when the feed liquid needs to be discharged from the reflux device 6, the feed liquid is discharged from the overflow port 9.

When a coating machine needs to be used, the overflow height is adjusted through the overflow extension pipe 2 and the overflow pipe 7, then, feed liquid enters the trough overflow area from the feeding pipe 1 and is mixed with the feed liquid, the feed liquid is filtered by the filter screen 8, impurities in the feed liquid are intercepted in the overflow area, the filtered feed liquid enters the filtering round pipe 3, after the feed liquid height in the filtering round pipe 3 exceeds the overflow height, the feed liquid overflows into the backflow device 6, the backflow device 6 sends the feed liquid without impurities into the backflow area through the backflow pipe 5, a coating stick of the coating machine is at least partially immersed in the feed liquid in the backflow area, and coating process production is carried out.

In order to ensure that the feed liquid in the reflux area is not influenced by impurities generated in the coating process, the feed liquid in the reflux area can be guided into the overflow area of the trough to be filtered after the coating process is carried out for a period of time, and a circulating device can be arranged between the reflux area and the overflow area, so that the feed liquid can flow circularly in the production process, and the influence of the impurities generated in the production process on the quality of a finished product is avoided. While the principles of the invention have been described in detail in connection with the preferred embodiments thereof, it will be understood by those skilled in the art that the above-described embodiments are merely illustrative of exemplary implementations of the invention and are not limiting of the scope of the invention. The details in the embodiments do not constitute the limitations of the scope of the present invention, and any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the present invention all fall within the protection scope of the present invention without departing from the spirit and scope of the present invention.
