The telescopic plate 104 is provided with a plate shell 105, and a guide plate 106 and a vibrating member are installed below the filter plate 103. The feeding component 2 is installed on the filtering box 1. The feeding component 2 includes a feeding hopper 201. An opening is provided above the feeding hopper 201 to communicate with the outside. The inner wall of the opening is connected with a control plate 202. A sealing sleeve 203 is connected to the periphery of the control plate 202 and a connecting plate 204 is installed above it. The connecting plate 204 is provided with an electric push rod a205. And the cleaning component 3 is installed on the filtering box 1. The frame 102 is used to limit the up and down vibration of the filter plate 103, effectively preventing the kraft paper pulp from flowing into the bottom of the filtering box 1 through the gap between the filter plate 103 and the filtering box 1. The telescopic mechanisms of the telescopic plate 104, the plate shell 105 and the guide plate 106 enable them to synchronously expand and contract up and down with the filter plate 103, facilitating the improvement of the up and down vibration stability of the filter plate 103 and enhancing the practicability of the kraft paper pulp filtering device. Moreover, the control plate 202 moves up and down to adjust the distance between it and the feeding hopper 201, and the distance between the control plate 202 and the feeding hopper 201 is the feeding port, which is used to feed the kraft paper pulp to be filtered into the filtering box 1 for processing.

[0032] Further explanation, the filtering box 1 is installed with a discharge cover 101, which is opposite to the discharge port of the filtering box 1 and is used to discharge the filtered kraft paper pulp from the filtering box 1. A cover body 110 is installed on the filtering box 1 for installing the cleaning component 3. The discharge port is parallel to the filter plate 103, so that the cleaning component 3 can cooperate to discharge the kraft paper pulp on the filter plate 103 from the filtering box 1.

The connecting plate 204 drives the control plate 202. The control plate 202 moves upward to open the discharging port of the feeding hopper 201, so that the kraft paper pulp to be filtered and processed is added into the filtering box 1 through the feeding hopper 201. By controlling the movement of the control plate 202, the size of the feeding port of the feeding hopper 201 is controlled, facilitating the control of the kraft paper pulp added into the filtering box 1 and flattening the kraft paper pulp to be filtered and processed through the control plate 202, so as to improve the filtering effect. At the same time, when the end of the kraft paper pulp entering the filtering box 1 through the feeding hopper 201 is blocked and piled up, first move the control plate 202 downward, and then start the electric push rod b208. The driving end of the electric push rod b208 penetrates through the feeding hopper 201 and is connected to the discharging plate 209. The discharging plate 209 moves into the filtering box 1 through the electric push rod b208, so as to push the blocked and piled up kraft paper pulp into the filtering box 1, facilitating the feeding of the kraft paper pulp; The kraft paper pulp enters the filtering box 1 through the feeding assembly 2. The vibrating motor 108 vibrates the filter plate 103 up and down to improve the filtering effect of the kraft paper pulp. During the up and down vibration of the filter plate 103, the upper and lower telescopic plates 104 of the filter plate 103 are stressed and telescoped into the plate shell 105, and the lower guiding plate 106 is telescoped, which will improve the stability of the up and down vibration of the filter plate 103 and facilitate the filtering and processing of the kraft paper pulp.
