The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 4 show an energy-saving electrophoresis apparatus for an electrophoresis line according to a preferred embodiment of the present invention. The electrophoresis apparatus comprises a tank body 1, an extracting tube 2, a delivery pump 3, a delivery tube 4 and a plurality of electrophoresis tubes 5 (the electrophoresis tubes 5 can be electrophoresis anode tubes or electrophoresis cathode tubes). The inner walls at both ends of the slot body 1 in the length direction are inclined structures 12, and the distance between the inner walls at both ends of the slot body 1 is gradually increased along the height direction. The electrophoresis tubes 5 are connected into the tank body 1, and the concentration of the electrophoresis tubes 5 in the tank body 1 is gradually sparse from the middle to the direction close to the inclined surface structure 12; the liquid outlet 11 of the tank body 1 is connected with the delivery pump 3 through the liquid suction pipe 2; the conveyer pipe 4 is located the bottom of cell body 1 to extend along the extending direction of cell body 1, conveyer pipe 4 is connected with a plurality of hydrojet pipes 6 along self length direction interval, and the orientation of hydrojet pipe 6 is the acute angle setting for the diapire of cell body 1, so that the electrophoresis tank liquid in the cell body 1 can carry out the circulation motion.

Referring to fig. 5 and 6, the chain 9 for conveying the work is constructed to be similar to the contour of the inner wall of the tank 1, i.e., both ends of the chain 9 located in the tank 1 are inclined, and the interval between both ends is gradually increased in the height direction. When the work piece is conveyed into the tank body 1 by the chain 9, the work piece firstly enters the electrophoresis tank liquid obliquely downwards for soaking, then horizontally moves for a certain distance, and then leaves the electrophoresis tank liquid obliquely upwards. During this time, the electric charges carried by the electrophoresis tube 5 and the chain 9 are opposite to each other, so that the electric charges of the work piece and the electrophoresis tank solution are opposite to each other, and the electrophoresis electrochemical reaction is promoted to generate an electrophoresis film on the surface of the work piece. In this embodiment, in order to facilitate insertion of the electrophoresis tube 5 into the tank body 1, the electrophoresis tube 5 has a U-shaped structure and is inserted upside down into the tank body 1.

Importantly, the inner walls at the two ends in the length direction of the tank body 1 are inclined structures 12, and the distance between the inner walls at the two ends of the tank body 1 is gradually increased along the height direction; so that the work piece can follow the chain 9 gently into the bath solution to provide a basic condition for convenient operation of the work piece. The concentration of the electrophoresis tubes 5 in the tank body 1 is gradually sparse from the middle to the direction close to the inclined surface structure 12, so that the electrophoresis electrochemical reaction at the position close to the inclined surface structure 12 is relatively mild, and the electrophoresis electrochemical reaction at the middle part of the tank body 1 is relatively intense, so as to match the actual situation that a workpiece is not completely immersed in the electrophoresis tank liquid when being positioned in the inclined surface structure 12, and avoid wasting electric energy. Based on the fact that the circulation distribution of the electrophoresis tank liquid is uneven when the tank body 1 is large, so that the uneven solid content of the electrophoresis tank liquid is easy to occur in the electrophoresis tank liquid, the conveying pipe 4 is arranged at the bottom of the tank body 1 and extends along the extending direction of the tank body 1, the conveying pipe 4 is connected with a plurality of liquid spraying pipes 6 at intervals along the length direction of the conveying pipe 4, the orientation of the liquid spraying pipes 6 is arranged at an acute angle relative to the bottom wall of the tank body 1, and the electrophoresis tank liquid in the tank body 1 can perform circulation motion; that is, the liquid spraying pipes 6 directly act on the bottom of the tank body 1, so that turbulence phenomenon is promoted, and the solid-liquid mixing of the electrophoresis tank liquid is more balanced, so that the uniformity of the electrophoresis electrochemical reaction is improved. The electrophoresis tank liquid of the tank body 1 is circularly conveyed to the conveying pump 3 through the conveying pump 3 and the liquid suction pipe 2, namely, the circulation movement of the liquid in the tank body 1 is promoted in an internal circulation mode, so that the arrangement mode is effective and simple.

Based on the fact that the outlet aperture of the delivery pump 3 is generally smaller, resulting in a faster flow rate, and the length of the delivery tube 4 is longer, during long distance delivery, the high resistance caused by the high flow rate results in the need to select a delivery pump 3 of high power according to the fluid resistance formula, thereby increasing production costs. Preferably, the caliber of the delivery tube 4 is greater than the caliber of the outlet of the delivery pump 3, the outlet of the delivery pump 3 being connected to the delivery tube 4 by a flared section 7. The arrangement is based on the fact that the caliber of the conveying pipe 4 is larger than that of the outlet of the conveying pump 3, and the outlet of the conveying pump 3 is connected with the conveying pipe 4 through the flaring section 7, so that the speed of the electrophoresis tank liquid is slower when the electrophoresis tank liquid is conveyed in the conveying pipe 4 with a large length, and the power of the conveying pump 3 is allowed to be reduced to reduce the production cost. Further, the axis of the delivery tube 4 is arranged coaxially with the outlet of the delivery pump 3; so that no bending section exists between the delivery pump 3 and the delivery pipe 4, thereby further reducing the fluid resistance, and further reducing the energy consumption, namely further reducing the power of the delivery pump 3 and the production cost.

In order to increase the turbulence degree of the electrophoresis tank liquid in the tank body 1 and thereby further increase the uniformity of the electrophoresis electrochemical reaction, it is preferable that the plurality of transport pipes 4 are provided, and the plurality of transport pipes 4 are arranged in parallel with each other at a spacing in the horizontal direction, and the plurality of transport pipes 4 are connected with respective transport pumps 3, respectively, as seen in fig. 1.

In order to make the resistance to the flow of the liquid at the bottom of the tank body 1 smaller, so as to promote the stability of the circulation movement of the electrophoresis tank liquid; preferably, the bottom of the tank body 1 is filled with a buried layer 8, the part of the conveying pipe 4 located in the tank body 1 is buried by the buried layer 8, and the liquid spraying pipe 6 penetrates through the buried layer 8 and leaks into the tank body 1. The buried layer 8 is preferably a concrete layer, but it is understood that the buried layer 8 may be made of other materials.

Preferably, in order to avoid a reduction in the turbulence level of the solution in the tank 1 during the internal circulation of the electrophoretic tank solution in the tank 1 by the transfer pump 3, the liquid outlet 11 of the tank 1 is provided at the top of the tank 1. So arranged, the liquid outlet 11 is situated farther from the transfer tube 4, so that there is less interference between the two.

Preferably, in order to be able to further reduce the power of the transfer pump 3, the liquid outlet 11 of the tank 1 is provided directly above the transfer pump 3. More preferably, the liquid suction pipe 2 is of a straight pipe structure, and the liquid suction pipe 2 is vertically arranged. In this way, the straight pipe structure has smaller fluid resistance than the bent pipe structure, and the power of the transfer pump 3 can be reduced.

Preferably, in order to enable the liquid spraying tube 6 to generate a circulating motion of the electrophoresis tank liquid, the liquid spraying tube 6 is oriented at an acute angle A which is less than or equal to 45 degrees relative to the bottom wall of the tank body 1, wherein the acute angle A can also be 30 degrees, 15 degrees, 5 degrees and the like.

The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
