The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0018] A screen changer, such as Figure 1, including a flow channel body 10, a screen changing plate 20, a driving cylinder 30 and a driving switching assembly 40. The flow channel body 10 is provided with a feed port and a discharge port 11. The driving cylinder 30 and the screen changing plate 20 are distributed and arranged in the vertical direction. The bracket of the driving cylinder 30 is installed on the flow channel body 10 by bolts. The driving cylinder 30 is generally a hydraulic cylinder. The screen changing plate 20 is provided with two groups, that is, the driving cylinder 30 and the screen changing plate 20 are arranged on a vertical plane, which changes the problem of the increase in the overall length of the screen changer caused by the coaxial arrangement of the driving cylinder and the screen changing plate of the traditional screen changer, effectively solves the installation problems in some narrow spaces, and avoids interference with surrounding equipment.

[0019] A power connection body 60 is provided at the end of the screen changing plate 20, and a matching part 61 is provided on the power connection body 60.

The switching connection part 43 is movably installed on the transmission body 44 and can switch and connect the matching parts 61 on different screen changing plates 20, so that one driving cylinder 30 can switch and drive two screen changing plates 20.

[0020] Specifically, Figure 2 The mating portion 61 is a mating groove provided on the power connection body 60, and the switching connection portion 43 can be inserted into the mating groove to realize the connection. The mating grooves on the two screen changing plates 20 are relatively open, so that the switching connection portion 43 can be seamlessly switched between the two mating grooves, that is, when moving the switching connection portion 43, there is no need to first pull out the switching connection portion 43 and then move it, but it can be directly moved from one mating groove to another. The transmission body 44 is a rod, which is connected to the piston rod of the drive cylinder 30 by bolts. A slide groove 41 is provided on the transmission body 44, and the switching connection portion 43 is installed in the slide groove 41. The movement and switching of the switching connection portion 43 can be manually controlled or automatically controlled; when manually controlled, such as Figure 3 , a positioning hole 62 is provided in the matching groove, a handle 42 is provided on the switching connection part 43, and the handle 42 is installed on the switching connection part 43 so as to be movable and retractable, and one end of the handle 42 can be inserted into the positioning hole 62 to fix the position of the switching connection part 43. During automatic control, a switching drive component, such as a pneumatic or electric slide rail, a cylinder, etc., is provided on the transmission body 44, and the switching connection part 43 is connected to the switching drive component to realize automatic switching.

[0021] When the screen needs to be changed, the switching connection part 43 is inserted into the corresponding matching part 61, and the driving cylinder 30 is started to move the screen changing plate 20 to the outside of the flow channel body 10 to change the screen.
