DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiments

[0035] See also Figure 1-2 As shown, it is the first embodiment of the utility model, which provides a medical horizontal electrophoresis tank, including an electrophoresis tank body 1 and an overflow assembly 2, and the overflow assembly 2 includes a shell 201, a drain pipe 202, an L-shaped frame 203, a liquid collecting shell 205 and a hose 206. The L-shaped frame 203 drives the liquid collecting shell 205 to rise and fall, and the excess liquid is discharged through the drain pipe 202, the liquid collecting shell 205 and the hose 206. The setting of the drain pipe 202 made of a hard tube material increases its sealing performance, solving the problem of poor sealing performance in the prior art;

[0036] Specifically, the shell 201 vertically penetrates the center position of the front end surface of the electrophoresis tank body 1, and a drain pipe 202 penetrates below the front end surface of the shell 201. One end of the drain pipe 202 extends to the inner side of the shell 201. The inside of the shell 201 is vertically movably connected with an L-shaped frame 203. The vertical arm of the L-shaped frame 203 penetrates a connecting pipe 204. One end of the connecting pipe 204 is fixedly connected to a liquid collecting shell 205. The other end of the connecting pipe 204 is fixedly connected to a hose 206. The end of the hose 206 away from the connecting pipe 204 is located at the same position as the drain pipe 202. One end of the inner side of the shell 201 is fixedly connected, and the shell 201 is used to install structures such as a drain pipe 202. The drain pipe 202 is made of a hard pipe material. The excess electrophoresis liquid in the electrophoresis tank body 1 is discharged through the setting of the drain pipe 202. The L-shaped frame 203 is used to install structures such as a connecting pipe 204 and adjust the height of the liquid collecting shell 205. At the same time, the connecting pipe 204 and the liquid collecting shell 205 are used to overflow the excess liquid. The hose 206 is used to connect the connecting pipe 204 and the drain pipe 202.

[0037] Furthermore, a liquid inlet pipe 101 is passed through the outer wall of one side of the electrophoresis tank body 1, and a liquid inlet valve 102 is fixedly connected to one end of the liquid inlet pipe 101 located outside the electrophoresis tank body 1.

[0040] The operation process of this embodiment is as follows: first, the raw material is placed on the inner side of the electrophoresis tank body 1, and the overflow height is adjusted according to the height of the raw material, and the first knob 203b is turned. The first knob 203b drives the first threaded rod 203a to rotate synchronously, and under the action of the threaded connection between the first threaded rod 203a and the shell 201, the first threaded rod 203a drives the L-shaped frame 203 to move up and down, and drives the liquid collecting shell 205 to move up and down through the L-shaped frame 203. When the liquid collecting shell 205 moves to a specified height, the first knob 203b is stopped from being turned, and finally, electrophoresis liquid is added to the electrophoresis tank body 1 through the liquid inlet pipe 101. When the electrophoresis liquid in the electrophoresis tank body 1 reaches a certain liquid level height, its excess electrophoresis liquid is discharged through the liquid collecting shell 205, the connecting pipe 204, the hose 206 and the drain pipe 202 in turn, and at the same time, the electrophoresis tank body 1 is energized to achieve electrophoresis of the raw material.
