Description

Technical Field

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

[0002] Filter presses are used for solid-liquid separation in chemical, petroleum, mineral processing, pharmaceutical, sludge treatment and food industries. Existing filter presses are currently single-station processes: after each feeding of material to be filtered, the material in the filter press must be separated into solid and liquid before the next feeding can be carried out. This results in low filtration efficiency and the inability to achieve continuous filtration. Utility Model Content

[0005] The aforementioned filter press has at least the following beneficial effects: During filter pressing, two sets of drive components move and push the filter pressing components toward the thrust member. The inlet connector of the diverter connects to the external material source. One diverter connector opens, and the feed connector of the thrust member, which is connected to the diverter connector, guides the material into the filter pressing space of the filter pressing component. When this set of filter pressing components reaches its filter pressing limit, the diverter switches to another diverter connector, allowing the material to enter another set of filter pressing components through the feed connector of the other thrust member, thus achieving continuous and uninterrupted filter pressing production. While the other set of filter pressing components is operating, the filter pressing component that has reached its filter pressing limit can be used to remove the filtered solids. Compared with previous filter presses, this application optimizes the overall structure and sets two sets of filter pressing components to operate alternately and switch between them via the diverter, enabling continuous and uninterrupted filter pressing production. Simultaneously, while one set of filter pressing components is operating, the other set can separate the filtered solids and prepare for the next filter pressing, significantly improving filter pressing efficiency.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0031] Reference Figure 1 and Figure 2 This application provides a filter press, which includes a fixed frame, a thrust member 230, a pressing member 210, a filter pressing component, a driving member 140, and a diverting member 240.

[0032] There are two thrust members 230, which are fixed in the middle of the fixed frame.

[0033] There are two clamping members 210. The clamping members 210 are slidably disposed on the fixed frame and can move closer to or away from the thrust member 230. The thrust member 230 is located between the two clamping members 210.

[0034] It should be noted that a filter press component is provided between the clamping component 210 and the thrust component 230. The filter press component can slide along the axial direction of the fixed frame. Both ends of the fixed frame are provided with driving components 140. The driving components 140 are used to drive the clamping component 210 toward the thrust component 230 so that a filter press space is formed between the filter press components, which facilitates the filter press operation.

[0035] Among them, a thrust member 230, a clamping member 210, a filter press component and a driving member 140 form a filter press working unit, that is, two sets of filter press working units are symmetrically arranged on the fixed frame.

[0036] Specifically, during the filter press operation, the two sets of drive components 140 actuate and push the filter press components toward the thrust member 230. The inlet connector of the diverter 240 is connected to the external material source. One of the diverter connectors opens, and the first set of filter press operation sections is connected. The feed connector 232 of the thrust member 230, which is connected to the diverter connector, guides the material into the filter press space of the filter press component. When the first set of filter press operation sections reaches the filter press limit, the diverter 240 switches to another diverter connector to open, and the second set of filter press operation sections is connected, so that the material enters another set of filter press components through the feed connector 232 of another thrust member 230. Through the alternating filter press operation of the two sets of filter press operation sections, continuous and uninterrupted filter press production is achieved. While one set of filter press components is operating, the other set of filter press components, which has reached the filter press limit, can remove the filtered solids.

[0037] Compared with previous filter presses, this application optimizes the structure of the whole machine and sets up two sets of filter pressing components to work alternately and switch the conveying through the diverter 240, which can realize continuous and uninterrupted production of filter pressing. At the same time, while one set of filter pressing components is working, the other set can separate the filtered solids and prepare for the next filter pressing, which greatly improves the filter pressing efficiency.

[0038] In some embodiments, the fixing frame includes two parallel beam members 110, and both ends of the thrust member 230 are provided with connecting portions 233 that engage with the beam members 110. A separator 180 is provided between the connecting portions 233 of the two thrust members 230, and the separator 180 is fixedly connected to the beam members 110.

[0039] The thrust member 230 is quickly positioned by the separator 180. When the drive member 140 drives the clamping member 210 to press the filter press component toward the thrust member 230, misalignment or displacement is less likely to occur, resulting in better filtration. Furthermore, the connection part 233 engages with the beam member 110, making the assembly and disassembly of the thrust member 230 more convenient.

[0040] It should be noted that the clamping component 210, the filter press component, and the thrust component 230 share the same beam component 110, which makes the sliding of the clamping component 210 and the filter press component smoother.

[0041] In some embodiments, the filter press further includes two parallel support members 250, one end of which is fixedly connected to the bottom of one of the thrust members 230, and the other end of which is fixedly connected to the bottom of the other thrust member 230.

[0042] like Figure 3 As shown, two support members 250 are set at the bottom of the thrust member 230. The thrust member 230 is supported by the support members 250. Since the thrust member 230 is snapped into the beam structure, the support members 250 also serve to support the middle position of the beam member 110. This can prevent the middle part from deforming and sinking due to the excessive span of the beam structure, and effectively improve the service life of the filter press.

[0043] In some embodiments, such as Figure 3 As shown, the diversion component 240 includes a first pipe 241, a second pipe 242, and a third pipe 243. The first pipe 241 serves as a feed pipe, and the second pipe 242 and the third pipe 243 serve as diversion pipes. The second pipe 242 and the third pipe 243 are respectively connected to the feed connectors 232 of the two thrust members 230, and both the second pipe 242 and the third pipe 243 are equipped with solenoid valves 244 for controlling the on and off states.

[0044] In some embodiments, such as Figure 4 and Figure 5 As shown, the thrust member 230 includes a thrust body 231 and a reinforcing structure disposed on one side of the thrust body 231. The other side of the thrust body 231 is provided with a filter groove that cooperates with the filter press component. The filter groove can form a filter press space with the filter press component for solid-liquid separation of materials. The reinforcing structure can improve the structural strength of the thrust body 231 and prevent the thrust member 230 from deforming due to repeated high-load compression.

[0045] Specifically, such as Figure 5 As shown, the reinforcing structure includes two first horizontal plates 234 and a vertical plate 236. The two first horizontal plates 234 are disposed in the middle of the thrust body 231. The first horizontal plates 234 are arranged in a horizontal direction. The ends of the two first horizontal plates 234 are formed as connecting parts 233, that is, the two connecting parts 233 on the same side form a notch for engaging the beam member 110. Vertical plates 236 are arranged in an array on both sides of the first horizontal plates 234. At least one end of the vertical plate 236 is fixedly connected to the first horizontal plate 234. The reinforcing structure formed by the first horizontal plates 234 arranged in the horizontal direction and the vertical plates 236 arranged in the vertical direction can effectively improve the structural strength of the thrust body 231 and reduce the probability of deformation.

[0046] In some embodiments, a through hole is provided in the middle of the thrust body 231, and a feed connector 232 is provided on the side with the reinforcing structure.

[0047] Furthermore, the reinforcing structure also includes a second horizontal plate 235, which is respectively disposed on the upper and lower sides of the thrust body 231. Two first horizontal plates 234 are located between the two second horizontal plates 235. One end of the vertical plate 236 located between the first horizontal plate 234 and the second horizontal plate 235 is connected to the first horizontal plate 234, and the other end is connected to the second horizontal plate 235. Both ends of the vertical plate 236 located between the two first horizontal plates 234 are respectively connected to the two first horizontal plates 234.

[0048] Specifically, such as Figure 6 As shown, the support member 250 includes a cross brace 252 and a support column 251. The end of the cross brace 252 is connected to the thrust member 230 by fasteners. The support column 251 is connected to the middle of the cross brace 252. A reinforcing member 253 is provided between the support column 251 and the cross brace 252.

[0049] The bottoms of the two thrust members 230 are connected by a cross brace 252, while the support column 251 supports the middle of the bottom of the cross brace 252. To prevent the cross brace 252 from deforming due to excessive load, a reinforcing member 253 is provided between the cross brace 252 and the support column 251. One end of the reinforcing member 253 is connected to the end of the cross brace 252, and the other end of the reinforcing member 253 is connected to the end of the support column 251, so that the reinforcing member 253, the cross brace 252 and the support column 251 form a stable triangular structure.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the fixing frame also includes two load-bearing components 120. The ends of the two beam components 110 are detachably connected to the two sides of the load-bearing components 120, and the driving component 140 is fixed to the load-bearing components 120.

[0051] The two load-bearing components 120 serve as the load-bearing foundation of the entire filter press. The load-bearing components 120, together with the beam component 110, can withstand heavy loads. The load-bearing components 120 support both ends of the beam component 110, and together with the support component 250, the overall structure becomes more stable.

[0052] In some embodiments, the drive component 140 is a hydraulic cylinder, which is fixed to the load-bearing component 120, and the cylinder rod is connected to the clamping component 210.

[0053] In some embodiments, the filter press component includes several filter plates 220. Each filter plate 220 has a second overlapping portion 222 on both sides, which overlaps with the beam member 110. The other two sides of the aluminum plate have recesses 2211. Adjacent filter plates 220 can form a filter press space. A material passage hole 2212 for material to pass through is provided in the middle of each filter plate 220. The second overlapping portion 222 allows the filter plate 220 to slide on the beam member 110. To make the sliding of the filter plate 220 smoother, ball bearings or roller bearings can be provided between the second overlapping portion 222 and the beam member 110 to reduce friction.

[0054] During the filter press operation, a filter press space is formed between two adjacent filter plates 220. The material enters and exits the filter press space through the material passage 2212. Because filter paper is set between two adjacent filter plates 220, water can flow out of the filter press space through the filter paper, while the solid part can remain in the filter press space, thereby achieving solid-liquid separation.

[0055] In some embodiments, such as Figure 8 As shown, the clamping member 210 has a first overlapping portion 211 on both sides, which overlaps with the beam member 110. The overlapping method allows the clamping member 210 to slide. To further facilitate the sliding of the clamping member 210, ball bearings or roller bearings can be provided between the first overlapping portion 211 and the beam member 110 to reduce friction. To improve the structural strength of the clamping member 210, a hollow structure 212 is provided on the side of the clamping member 210 connected to the driving member 140.

[0056] In some embodiments, the filter press further includes a recovery assembly, which includes a reset hook structure 160 capable of linear reciprocating motion, the reset hook structure 160 being used to reset the filter press components.

[0057] Specifically, the recycling component includes a guide rail 130 mounted on the beam member 110, a reset hook structure 160 slidably mounted on the guide rail 130, and a drive shaft 150 and a conveyor chain. The drive shaft 150 is connected to the reset hook structure 160 via the conveyor chain, and the drive shaft 150 is rotated by a motor 170, thereby driving the reset hook to reciprocate.

[0058] In some embodiments, such as Figure 9 As shown, the reset hook structure 160 includes a mounting slider 161 and a first hook 162 and a second hook 163 capable of reset. A groove for locking the second overlapping part 222 is formed between the first hook 162 and the second hook 163. The first hook 162 and the second hook 163 are disposed on the mounting slider 161.

[0059] When it is necessary to separate the two filter plates 220 in sequence, the reciprocating motion of the reset structure, together with the slot formed by the first hook 162 and the second hook 163, can quickly separate the filter plates 220 so that the filter space can be opened and the solid formed can fall out of the filter space.

[0060] Other components and operations not mentioned in the above-described pressure filtration are already described in related technologies by those skilled in the art, and will not be described in detail here.

[0061] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above 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 application.
