This application can achieve higher separation efficiency without affecting the service life.

Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and in particular to a separation device for a filter press. Background Technology

[0002] In the production process, when solid-liquid separation is required, a filter press is usually used. A filter press is a mechanical device that uses a special filter medium to apply pressure to the material, causing the liquid to seep out. It is a commonly used solid-liquid separation device. It was applied to chemical production in the early 18th century and is still widely used in industries such as chemicals, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection.

[0003] After filtration, solids tend to adhere to the plates and frames, making them difficult to remove. Chinese patent CN218944445U describes a plate and frame filter press, which includes two support frames, a filtration device, a vibration device, and a limiting device. The two support frames are arranged opposite each other, with the filtration device for processing high-purity enzyme products positioned between them. Vibration devices are fixedly connected to the bottom of each support frame, and the limiting devices are mounted on the support frames. This plate and frame filter press, through its vibration device, allows for cleaning of the filter cloth. When the filter cloth needs cleaning, the operator starts the motor, which drives the eccentric wheel to rotate, causing the top plate to vibrate up and down, thus vibrating the entire device and cleaning the filter cloth.

[0004] The above technology has the following problems: In actual production, vibration will impact the connection structure of the entire equipment, affecting the service life of the entire equipment. Utility Model Content

[0005] In view of this, it is necessary to provide a filter press separation device that can separate solid filter materials without affecting the service life.

[0006] This utility model provides a filter press separation device, comprising:

[0007] A filter press assembly includes a support, multiple filter plates, and a displacement member. The filter plates are slidably mounted on the support. The displacement member is connected to the filter plates and drives them to move relative to the support, so that the multiple filter plates can be in a filtration state with close contact and in a non-filtration state with gaps formed between them.

[0008] The separation assembly includes a lifting frame, a lifting component, and several scraper plates. The lifting component is mounted on the lifting frame in a liftable manner. The scraper plates are fixed to the lifting component and are matched one-to-one with the filter plates in the non-filtering state. The lifting component moves up and down along the lifting frame so that the scraper plates come into contact with the surface of the filter plates in the non-filtering state.

[0009] In other embodiments, the lifting component includes a slider and a fixed plate. The slider is slidably connected to the lifting frame and can slide along the lifting frame and stop at any position within its sliding stroke. The fixed plate is fixed to the slider, and the scraper is fixed to the fixed plate.

[0010] In other embodiments, the separation assembly further includes a spray assembly fixed to the fixed plate and having a plurality of spray ends that correspond one-to-one with the filter plate in the non-filtering state.

[0011] In other embodiments, the spray assembly includes a liquid storage tank, a spray pump, and multiple spray heads. The liquid storage tank, the spray pump, and the multiple spray heads are fixed on the fixed plate. The liquid outlet of the liquid storage tank is connected to the liquid inlet of the spray pump, and the liquid outlet of the spray pump is connected to the pipes of the multiple spray heads. Each spray head corresponds to and matches one-to-one with the filter plate in the non-filtering state.

[0012] In other embodiments, the support has a movable hole, the filter plate is disposed in the movable hole and slidably connected to the support, and a plurality of filter plates are arranged sequentially on the support, with the filter plate at the end being fixed to the support.

[0013] In other embodiments, the filter press includes a frame and a filter membrane. The frame has a filtrate inlet and a filtrate outlet. The filter membrane covers the area between the filtrate inlet and the filtrate outlet. When the filter press is in the filtration state, adjacent filter presses abut tightly, so that the filtrate inlets of each filter press are joined together to form a filtrate inlet channel, and the filtrate outlets of each filter press are joined together to form a filtrate outlet channel.

[0014] In other embodiments, the filter membrane and the frame form a closed space, and the frame is provided with an air pipe communicating with the closed space. When in the non-filtering state, air is periodically blown out into the closed space through the air pipe.

[0015] In other embodiments, the displacement component includes a telescopic cylinder and a plurality of connecting components. The telescopic cylinder is fixed on the bracket, and the movable end of the telescopic cylinder is fixed to the filter plate located at the head end. The two ends of the connecting components are respectively connected to the adjacent filter plates.

[0016] In other embodiments, the filter press plate further includes a slider that is slidably connected to the support and fixed to the surface of the frame.

[0017] In other embodiments, the filter press assembly further includes a collection hopper located below the filter press plate, with the opening of the collection hopper corresponding to the filter press plate, for receiving material that falls off the filter press plate.

[0018] The beneficial effects of this utility model are as follows:

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a filter press separation device, which includes: a filter press assembly 1 and a separation assembly 2. The filter press assembly 1 includes a support 11, a plurality of filter press plates 12 and a displacement member 13. The filter press plates 12 are slidably disposed on the support 11. The displacement member 13 is connected to the filter press plates 12 and drives the filter press plates 12 to move relative to the support 11, so that the plurality of filter press plates 12 have a filter press state in which they are in close contact with each other and a non-filter press state in which they are separated from each other and form gaps. The separation assembly 2 includes a lifting frame 21, a lifting member 22 and a plurality of scraper plates 23. The lifting member 22 is slidably disposed on the lifting frame 21. The scraper plates 23 are fixed on the lifting member 22 and correspond one-to-one with the filter press plates 12 in the non-filter press state. The lifting member 22 moves up and down along the lifting frame 21 so that the scraper plates 23 contact the surface of the filter press plates 12 in the non-filter press state.

[0027] In this utility model, a lifting frame 21, a lifting component 22, and several scraper plates 23 are provided. The lifting component 22 is movably mounted on the lifting frame 21. The scraper plates 23 are fixed to the lifting component 22 and correspond one-to-one with the filter plates 12 in the non-filtering state. The lifting component 22 moves up and down along the lifting frame 21 so that the scraper plates 23 contact the surface of the filter plates 12 in the non-filtering state, scraping off the solid matter remaining on the surface of the filter plates 12, thereby cleaning the filter plates 12. This application differs from the vibration method in the prior art by separating solid matter through scraping, which can achieve higher separation efficiency without affecting the service life.

[0028] Specifically, the support 11 has a movable hole, and the filter plate 12 is disposed in the movable hole and slidably connected to the support 11.

[0029] Specifically, multiple filter plates 12 are arranged sequentially on the support 11, and the filter plate 12 located at the end is fixed to the support 11.

[0030] Specifically, the filter press 12 includes a frame 121 and a filter membrane 122. The frame 121 has a filtrate inlet and a filtrate outlet. The filter membrane 122 covers the area between the filtrate inlet and the filtrate outlet. When the filter press is in the filtration state, adjacent filter presses 12 are tightly abutted together so that the filtrate inlets of each filter press 12 are joined together to form a filtrate inlet channel, and the filtrate outlets of each filter press 12 are joined together to form a filtrate outlet channel.

[0031] Furthermore, the filter membrane 122 and the frame 121 form a closed space. The frame 121 is provided with an air pipe 121a that communicates with the closed space. When in the non-filtering state, air is periodically blown out into the closed space through the air pipe 121a, causing the substances remaining on the surface of the filter membrane 122 to fall off.

[0032] Furthermore, the filter press plate 12 also includes a slider 123, which is slidably connected to the support 11 and fixed to the surface of the frame 121. Under the action of external force, the slider 123 enables the frame 121 to slide along the support 11.

[0033] Specifically, the displacement component 13 includes a telescopic cylinder 131 and multiple connecting components 132. The telescopic cylinder 131 is fixed on the bracket 11, and the movable end of the telescopic cylinder 131 is fixed to the filter plate 12 located at the first end. The two ends of the connecting components 132 are respectively connected to the adjacent filter plates 12. In use, the movable end of the telescopic cylinder 131 extends, pushing the multiple filter plates 12 to gradually press together, forming a material space between the filter plates 12. The filtrate is introduced into each of the material spaces through the filtrate inlet channel and then discharged through the drain channel. The solid matter remains on the filter membrane 122. After filtration is completed, the movable end of the telescopic cylinder 131 retracts, causing the multiple filter plates 12 to gradually separate, and the solid material falls off the filter membrane 122.

[0034] Furthermore, the filter press assembly 1 also includes a collection hopper 14, which is located below the filter press plate 12. The opening of the collection hopper 14 corresponds to the filter press plate 12 and is used to receive the material that falls off the filter press plate 12.

[0035] Specifically, the lifting frame 21 is provided with a sliding rail along the vertical direction, and the lifting component 22 is slidably connected to the sliding rail, and can slide along the sliding rail and stop at any position in its sliding stroke.

[0036] Specifically, the lifting component 22 includes a lifting slider 221 and a fixed plate 222. The lifting slider 221 is slidably connected to the sliding track and can slide along the sliding track and stop at any position within its sliding stroke. The fixed plate 222 is fixed to the lifting slider 221, and the scraper 23 is fixed on the fixed plate 222. When the filter press 12 is in the filter pressing state, the lifting slider 221 descends along the sliding track, and the scraper 23 contacts the corresponding filter press 12, scraping off the solid material remaining on its surface into the collection hopper 14.

[0037] Furthermore, the separation component 2 also includes a spray component 24, which is fixed on the fixed plate 222 and has a plurality of spray ends that correspond one-to-one with the filter plate 12 in the non-filtering state, for spraying cleaning liquid onto the filter plate 12 to separate the solid material.

[0038] Furthermore, the spray assembly 24 includes a liquid storage tank 241, a spray pump, and multiple spray heads 242. The liquid storage tank 241, the spray pump, and the multiple spray heads 242 are fixed on the fixing plate 222. The liquid outlet of the liquid storage tank 241 is connected to the liquid inlet of the spray pump, and the liquid outlet of the spray pump is connected to the multiple spray heads 242 via pipes. Each spray head 242 corresponds to a filter plate 12 in the non-filtering state. The spray heads 242 spray liquid onto the surface of the filter membrane 122, softening and removing residual solids from its surface, thereby improving the separation effect of solids.

[0039] The beneficial effects of this utility model are:

[0040] This utility model includes a filter press assembly and a separation assembly. The filter press assembly includes a support, multiple filter press plates, and a displacement member. The filter press plates are slidably mounted on the support. The displacement member is connected to the filter press plates and drives the filter press plates to move relative to the support, so that the multiple filter press plates have a filter press state in which they are in close contact with each other and a non-filter press state in which they are separated and form gaps. The separation assembly includes a lifting frame, a lifting member, and a number of scraper plates. The lifting member is slidably mounted on the lifting frame. The scraper plates are fixed to the lifting member and correspond one-to-one with the filter press plates in the non-filter press state. The lifting member moves up and down along the lifting frame so that the scraper plates contact the surface of the filter press plates in the non-filter press state. In use, the lifting component moves up and down along the lifting frame so that the scraper plate comes into contact with the surface of the filter plate in the non-filtering state, scraping off the solid material remaining on the surface of the filter plate, thereby cleaning the filter plate. This application differs from the vibration method in the prior art by separating solid material through scraping, which can achieve higher separation efficiency without affecting the service life.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
