Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a filter press device for chemical production. Background Art

[0002] In the process of chemical production and processing, it is necessary to separate the solid and liquid of the product, so it is necessary to use the corresponding filter press device to filter the product to remove the liquid;

[0003] In the actual use of the existing filter press device, the product is introduced into the filter press frame, and then the driving mechanism drives the pressure plate to press the product in the filter press frame to achieve filtration. However, during the filtration process, the material is partially accumulated in the filter press frame, which affects the filtration effect. At the same time, when discharging, the solids after filtration are stuck in the filter press frame, and the discharge is not complete, requiring manual assistance, which is troublesome to operate. Therefore, we propose a filter press device for chemical production. Utility Model Content

After the filtration is completed, starting the drive motor can drive the filter press frame to flip, thereby realizing the export of solid materials in the filter press frame.

[0008] By adopting the above technical solution and setting the electric slider, when the filter press frame is flipped over for discharging, the electric slider can be used to drive the support plate to move, thereby moving the filter press frame to one side, thereby ensuring that the discharged solid material is convenient to receive.

[0009] As a preferred embodiment of the utility model, a plurality of evenly distributed vibrators are embedded at the bottom of the scraper.

[0010] By adopting the above technical solution and setting the vibrator, when the filter press frame is turned over to discharge the material, the pressure plate is lowered so that the scraper fits the bottom of the filter press frame. The vibrator is used to generate vibration, which is transmitted to the filter press frame to ensure complete discharge and avoid material jamming.

[0013] As a preferred embodiment of the utility model, a hopper is fixed at the middle of the top of the base, and a drain pipe is fixed at the tail end of the hopper.

[0014] By adopting the above technical solution, the hopper can receive the liquid filtered by pressure and discharge it through the drain pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The technical solution of the present application is a filter press device for chemical production. When the pressure plate is lowered for filtering, the servo motor drives the scraper to scrape the product in the filter press frame, so that the material is spread evenly in the filter press frame, thereby ensuring that the product is filtered evenly during filtering, thereby ensuring the filtering effect and avoiding the situation where the product is locally accumulated in the filter press frame and the filtering is not thorough.

[0017] The servo motor drives the filter press frame to flip and discharge the material, and the scraper descends to fit the bottom of the filter press frame. The vibrator is used to generate vibration, which is transmitted to the filter press frame. The fixed material in the filter press frame is discharged completely by vibration without manual assistance, thereby improving the discharge efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

After the filtration is completed, the driving motor 13 is started to drive the filter press frame 12 to flip, so as to realize the output of the solid material in the filter press frame 12;

[0028] Furthermore, a hopper 14 is fixed at the middle of the top of the base 1, and a drain pipe 15 is fixed at the tail end of the hopper 14. The hopper 14 is configured to receive the liquid filtered by pressure and drain it out through the drain pipe 15.

[0029] Furthermore, a limit slide groove is provided on the inner wall of the support plate 11, and an adapted limit slide block 17 is inserted into the inner cavity of the limit slide groove, and a second electric push rod 18 is fixed to the bottom of the limit slide groove, and the tail end of the second electric push rod 18 is fixed to the bottom of the inner cavity of the limit slide groove, and the outer wall of the limit slide block 17 is fixedly connected with a bearing plate 16.

[0030] like Figure 1 and 3 As shown; a plurality of evenly distributed vibrators 25 are embedded at the bottom of the scraper 21.
