[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0021] Reference Figures 1-2 As shown, a filtration device suitable for the production of diethyltoluene diamine includes a filter tank 1, a lifting frame 3, a screw 8, and a support 7. Vertical guide rails 2 are provided on the inner and outer walls of the side plates on both sides of the filter tank 1. The lifting frame 3 is inverted U-shaped, and two lifting frames 3 are respectively clamped on the side plates on both sides of the filter tank 1. The two are symmetrically arranged and are slidably connected to the guide rails 2. A horizontal support plate 4 is provided on the outer side of the lifting frame 3, and a longitudinal slot 5 adapted to the edge of the filter plate is provided on its inner side.

[0022] The bottom of both sides of the filter tank 1 is provided with a fixing plate 6. Two screws 8 are vertically inserted through the two support plates 4 respectively. The upper ends of both are rotatably mounted on the bracket 7, and the lower ends of both are rotatably mounted on the two fixing plates 6 respectively. The two are connected by a synchronous drive assembly. The support plate 4 is fixed with a fixing nut 9 that is threadedly connected to the screw 8.

[0023] More specifically, the synchronous drive assembly includes a motor 10 and a synchronous belt 11. The lower ends of both screws 8 pass through the fixing plate 6, and their lower ends are connected by the synchronous belt 11. The motor 10 is fixed to the bottom of the fixing plate 6, and its output shaft is connected to the lower end of the corresponding screw 8 for transmission. Specifically, the motor 10 is a geared motor.

[0024] In addition, the fixing plate 6 is connected to the bracket 7 by two vertical guide support rods 12. The guide support rods 12 pass through the support plate 4, and the support plate 4 is provided with a guide sleeve 13 that is slidably connected to the guide support rods 12.

[0025] In use, the filter plates are inserted into the two longitudinal slots 5 on the left and right sides. When the filter plates need to be replaced, the motor 10 is started. With the connection of the synchronous belt 11, the motor 10 drives the two screws 8 to rotate synchronously, which in turn drives the two lifting frames 3 to carry the filter plates up along the guide rail 2 until the filter plates are exposed from the top of the filter tank 1. Then, the original filter plates are pulled out to replace them with filter plates of other models. Example 2

[0026] As a preferred embodiment of this utility model, this embodiment adds an elastic pressure plate 16 and an elastic locking device to the first embodiment, specifically:

[0027] Reference Figures 3-4 As shown, one end of the two longitudinal slots 5 is connected by a transverse slot 14. Multiple longitudinal first compression springs 15 are fixed inside the transverse slot 14, and the outer ends of the multiple first compression springs 15 are connected by a transverse pressure plate 16.

[0028] The device also includes an elastic locking device, which includes a housing 17, a locking rod 18, and a second compression spring 19. The housing 17 is fixed to the upper slot plate of the longitudinal slot 5 or the transverse slot 14. The locking rod 18 is located inside the housing 17, with its upper part sliding through the top plate of the housing 17, a limiting plate 20 in its middle part, and its lower part sliding through the upper slot plate. Its lower end has an inclined surface 1801 facing away from the transverse slot 14. The second compression spring 19 is sleeved on the locking rod 18, with its upper and lower ends supported on the top plate of the housing 17 and the limiting plate 20, respectively. The filter plate has a locking hole corresponding to the lower end of the locking rod 18. When the filter plate is inserted into the longitudinal slot 5 or the transverse slot 14, the lower end of the locking rod 18 is inserted into the locking hole.

[0029] Before removing the original filter plate, first lift the locking rod 18 so that the lower end of the locking rod 18 disengages from the locking hole. At this time, the pressure plate 16, under the elastic force of multiple first compression springs 15, pushes the filter plate forward a certain distance. Then, the staff removes the original filter plate and inserts the new filter plate. During the insertion of the new filter plate, the new filter plate pushes the locking rod 18 upward through the inclined surface 1801. When the new filter plate is in place, the lower end of the locking rod 18 is inserted into the locking hole under the push of the second compression spring 19 to complete the locking of the new filter plate.

[0030] This device has a simple structure and a high degree of automation. Only one person is needed to replace the filter plate, making the replacement of the filter plate convenient and quick. With the cooperation of the elastic pressure plate 16 and the elastic locking device, the original filter plate can be pulled out more easily, further improving the convenience of filter plate replacement.

[0031] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
