[0002] The filter press uses a special filter medium to apply a certain pressure to the object, so that the liquid is dialyzed out. It is a mechanical device and is a commonly used solid-liquid separation equipment. At present, due to the large number of filter plates in the filter press, filtrate leakage is inevitable between the filter plates after long-term use. The leaked filtrate will pollute the working environment and the cost is high. Therefore, a filtrate recovery device is used, which can recover the leaked filtrate for treatment.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a filtrate classification recovery device for a plate and frame filter press.

[0025] Embodiment 1:

[0026] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a plate and frame filter press filtrate classification and recovery device, including a conveying and separation component 100, a collecting tank 300, a filtering component 400 and a drainage component 500.

[0027] Specifically, the conveying and separation component 100 includes a frame 101, a driving motor 102 arranged on the right side of the frame 101, a rotating shaft 103 arranged at the output end of the driving motor 102, a conveying mesh belt 104 rotatably connected to the rotating shaft 103, and a support plate 105 arranged at the bottom of the frame 101. The driving motor 102 can be controlled to operate. The operation of the driving motor 102 will drive the conveying mesh belt 104 to rotate through the rotating shaft 103. The rotating conveying mesh belt 104 will convey the filter residue for unloading, and at the same time can filter the filter residue and leaked filtrate to separate and recover the filtrate. A fixed shaft 107 is arranged on the top of the frame 101, and iron rings 108 are arranged on both sides of the frame 101.

[0028] Furthermore, a T-shaped rotating rod 106 is threadedly connected to the support plate 105 , and the T-shaped rotating rod 106 can be rotated to press against the collecting tank 300 so as to fix the collecting tank 300 .

[0029] Specifically, the collecting tank 300 is placed in the supporting plate 105 , and grooves 301 are provided on both sides of the collecting tank 300 . The rotating T-shaped rotating rod 106 can be inserted into the groove 301 to play a limiting role so as to fix the collecting tank 300 . A connecting pipe 302 is provided on the inner side of the collecting tank 300 .

[0030] Specifically, the filter assembly 400 includes a filter tube 401 inserted into the collecting tank 300 and a filter cloth 402 arranged on the inner side of the filter tube 401. A fastening knob 403 is threadedly connected to the filter tube 401. The filter tube 401 can be inserted into the connecting tube 302, and the fastening knob 403 is rotated to fix the filter tube 401. After fixation, secondary separation can be performed through the filter cloth 402 to avoid turbidity of the filtrate, which increases the difficulty of subsequent processing.

[0031] Specifically, the drainage component 500 includes a connector 501 threadedly connected to the collection tank 300, a hose 502 arranged on the right side of the connector 501, and a drainage pipe 503 arranged on the hose 502. The connector 501 can be fixed in the connecting pipe 302 by threaded connection. After fixation, the separated filtrate can be transported for use. At the same time, the drainage component 500 is detachable to prevent the drainage component 500 from blocking the collection tank 300 from moving away from the support plate 105.

[0032] Embodiment 2:

[0033] Reference Figure 1 , which is the second embodiment of the utility model, is different from the first embodiment in that it also includes a blocking component 200, the blocking component 200 includes a baffle 201 rotatably connected to the fixed shaft 107, an iron rod 202 arranged on the top of the baffle 201 and a thin rope 203 arranged on the baffle 201, the baffle 201 has a guiding effect to prevent the filtrate from splashing out, and when adjustment is needed, the baffle 201 can be rotated to a suitable angle, and after rotation, the thin rope 203 can be fixed on the iron ring 108 to collect the filtrate.

[0034] The working principle and use process of the utility model are as follows: when in use, the filtrate and the filter residue can fall onto the conveying mesh belt 104 of the conveying separation component 100. During the falling process, the baffle 201 of the blocking component 200 plays a guiding role to prevent the filtrate from splashing out. When adjustment is required, the baffle 201 can be rotated to a suitable angle. After rotation, the thin rope 203 can be fixed on the iron ring 108 to collect the filtrate. Then the filtrate and the filter residue can be filtered through the conveying mesh belt 104. After filtration, the filter residue can be transported out for collection, and the filtered filtrate can fall into the collecting tank 300 and pass through The filter cloth 402 of the filter assembly 400 performs secondary separation. After separation, the filtrate is transported through the connecting pipe 302, the hose 502 and the drain pipe 503 of the drainage assembly 500, thereby avoiding the turbidity of the filtrate and increasing the difficulty of subsequent processing, so as to facilitate use. When the collection tank 300 needs to be cleaned, the T-shaped rotating rod 106 can be rotated to disengage from the groove 301 of the collection tank 300. After disengagement, the connecting head 501 can be rotated again, and the direct connecting head 501 can be completely disengaged from the connecting pipe 302, so that the drainage assembly 500 can be disassembled. After disassembly, the collection tank 300 can be moved to disengage from the support plate 105 to clean the collection tank 300.
