[0038] See also Figure 5 The filtration mechanism 2 includes a filtration cylinder 21, which is constructed as a round roller structure, and its two ends are respectively fixedly connected with a rotating connection end 211, and the rotating connection end 211 is used to connect the support structure to support the filtration cylinder 21. In this embodiment, the support structure adopts a bearing and a bearing seat, and the rotating connection end 211 is connected to the bearing seat through a bearing. On the basis of this structure, the filtration cylinder 21 can rotate, which is convenient for matching with various functional partitions in the feeding mechanism 3. The filtration mechanism 2 also includes a plurality of filtration shells 22 connected to the outer ring surface of the filtration cylinder 21, and the filtration shells 22 are arranged along the axial direction of the filtration cylinder 21, and are not shorter than the cylinder length of the filtration cylinder 21. The plurality of filtration shells 22 are arranged in a circular shape in sequence along the circumferential direction of the outer ring surface of the filtration cylinder 21.

[0039] Combination Figure 6 In this embodiment, the suction filter housing 22 is constructed as a load-bearing cavity with a bottom end and four sides closed and a top end open. Its bottom end matches the curvature of the suction filter cylinder 21, so that it fits tightly to the surface of the suction filter cylinder 21. Its top end is also set in a curvature, and the circle formed by the top of each suction filter housing 22 is coaxial with the suction filter cylinder 21. In order to ensure the radial stability of the suction filter housing 22, a plurality of T-shaped plug-in partitions 212 are fixedly arranged along the axial direction on the outer ring surface of the suction filter cylinder 21. Each plug-in partition 212 is distributed at intervals. The two sides of the suction filter housing 22 are respectively provided with plug-in partition grooves 221 matching the plug-in partition 212. When installing, the suction filter housing 22 is inserted between the two plug-in partitions 212. A feed port 222 is provided on one side end of the suction filter housing 22. The feed port 222 is connected to the feeding mechanism 3, and the material enters the suction filter housing 22 through the feed port 222.

[0040] Combination Figure 6 , Figure 7 , Fig. 9The suction filtration mechanism 2 further includes a filter element 23 arranged in parallel along the axial direction in the suction filtration housing 22. The filter element 23 is used for collecting filtrate. For the convenience of disassembly, replacement and maintenance, the filter element 23 is detachably connected to the suction filtration housing 22. In this embodiment, the filter element 23 adopts a filter element structure that is easy to install and has a good filtering effect. Specifically, one end of the suction filtration housing 22 is provided with a first mounting hole 223 that matches the outer diameter of the filter element. The first mounting hole 223 is on the same side as the feed port 222, and the other end of the suction filtration housing 22 is provided with a second mounting hole 224 that matches the water outlet of the filter element. The filter element enters the installation housing through the first mounting hole 223, and the end can be sealed by a sealing connection structure such as a plug 225. The water outlet of the filter element passes through the second mounting hole 224 and is connected to the liquid outlet mechanism 4. Preferably, in order to facilitate the collection of filtrate, the suction filtration housing 22 is sealed at this end by a gland to form a collection chamber 226, and the liquid outlet mechanism 4 is connected through the collection chamber 226. In order to ensure the stable setting of the filter element, a limiting space 227 matching the shape of the filter element is further provided at the bottom of the filtration housing 22 .

[0041] In order to prevent the high-cost filter element from being worn out too quickly, in a preferred embodiment, the filter element adopts a low-precision large-aperture filter element, and the outer sleeve of the filter element is provided with a small-aperture filter cloth (not shown in the figure) with a higher precision than the filter element. When using it, only the filter cloth needs to be replaced. This structure can effectively save costs and reduce filter element wear.

[0042] See also Figure 3 , Figure 4 The filtration mechanism 2 further includes a tape assembly 24 that cooperates with the filtration shell 22. The tape assembly 24 includes a tape body 241, a driving roller 242 for driving the tape body 241 to rotate, a tensioning roller 244 for tensioning the tape body 241, and a plurality of squeezing rollers. The tape body 241 is a continuous closed annular structure, the bottom surface of which is wound around and covers a portion of the filtration shell 22, so that the covered filtration shell 22 constitutes a closed space. The annular interior of the tape body 241 is supported and tensioned by a driving roller 242, a tensioning roller 244 and various squeezing rollers, wherein the driving roller 242 is rotatably connected to the frame 1 through a bearing seat, and one end of the driving roller 242 is connected to a reducer 243 for driving the rotation thereof, and the reducer 243 is fixed by a fixing device; both ends of the tensioning roller 244 are connected to a tensioning frame 245 through a bearing seat, and one end of the tensioning frame 245 is hinged to the frame 1, and is driven by a tensioning cylinder 246 hinged to the frame 1, thereby applying a tensioning force to the tensioning roller 244, and the squeezing rollers are distributed between the driving roller 242 and the tensioning roller 244, and are constructed to be able to reciprocate toward the filtration shell so that the bottom surface of the tape body 241 is pressed against the filtration shell 22.

[0043] When in use, the material enters the suction filter housing 22 through the feeding mechanism 3 and the feeding port 222 of the suction filter housing 22. Since the suction filter housing 22 pressed by the tape body 241 is a closed space, as the material continues to enter, the material in the suction filter housing 22 is squeezed, and the filtrate enters the filter element cavity through the filter element, and flows into the liquid outlet mechanism 4 through the filter element outlet. At the same time, the suction filter cylinder 21 and the suction filter housing 22 continue to rotate with the tape body 241, and the suction filter housing 22 that completes the suction filtration part gradually rotates to a position where the bottom is not covered by the tape body 241. At this time, the filter cake in the bottom suction filter housing 22 can be unloaded.

[0044] Preferably, the squeezing roller further comprises a sealing squeezing roller 247 and a partition squeezing roller 248, such as Figure 4 As shown, two sealing squeeze rollers 247 are provided, and the position of the sealing squeeze roller 247 determines the range of the suction filtration housing 22 sealed by the tape body 241, so the position of the sealing squeeze roller 247 should be as close to the bottom of the suction filtration cylinder 21 as possible. Both ends of the sealing squeeze roller 247 are slidably connected to the frame 1 through a slidable bearing seat, and the bearing seat is driven by a corresponding oil cylinder. Multiple partition squeeze rollers 248 can be provided, which need to correspond to different intervals set in the feeding mechanism 3. For example, the feeding mechanism 3 is not only provided with a feeding interval, but also a washing interval, an air drying area, a discharge area, etc. As the suction filtration cylinder 21 rotates, the suction filtration housing 22 corresponds to each interval in turn to achieve continuous operation. Similarly, the partitioned squeezing rollers 248 divide the circular ring of the filtration shell 22 into partitions, and the partitioned squeezing rollers 248 are distributed between the sealing squeezing rollers 247. Each partitioned squeezing roller 248 is also slidably connected to the frame 1 through a slidable bearing seat, and passes through the corresponding cylinder area respectively. In this embodiment, the matching structure of the cylinder and the roller belongs to the prior art, and its structure will not be further described here.

[0045] See also Figure 7-Figure 9 The feeding mechanism 3 includes a feeding pipe 31 connected to the feeding port 222 of each suction filter housing 22, and a feeding distribution assembly. To facilitate fixing the feeding pipe 31, the rotating connecting end 211 of the suction filter cylinder 21 is provided with an annular protrusion 2111, as shown in FIG. Figure 5 As shown, a plurality of mounting holes for connecting the feed pipe 31 are provided on the annular protrusion 2111. In the present embodiment, the feed pipe 31 is constructed in an L shape, one end of which passes through the mounting hole and is connected to the feed distribution assembly, and the other end is radially arranged and connected to the feed port 222 through a transition connection block 32. The transition connection block 32 is provided with a flow channel, which is fixedly connected to the side end of the filtration housing 22 by bolts.

[0046] The feed distribution assembly includes a dynamic distribution part and a static distribution part. The dynamic distribution part includes a distribution movable ring 33 fixedly connected to the end of the rotating connection end 211 and a distribution pressure plate 34 connected to the distribution movable ring 33. The distribution movable ring 33 and the rotating connection end 211 can be fixed by bolts. The distribution movable ring 33 and the distribution pressure plate 34 can be connected by bonding or hot pressing, etc., which can be selected according to actual needs. The distribution movable ring 33 and the distribution pressure plate 34 rotate synchronously with the filtration cylinder 21. The distribution movable ring 33 and the distribution pressure plate 34 are respectively provided with feed holes corresponding to the feed pipe 31. The distribution movable ring 33 is constructed in a circular plate shape. The distribution pressure plate 34 is made of wear-resistant ceramic material, and its other side is in contact with the static distribution part, see Fig.10 The distribution plate 34 is surrounded by a limiting portion 341, which is constructed as a barrier structure to ensure accurate alignment with the distribution dynamic ring 33 and the static distribution portion, and can also play a certain sealing role to prevent material leakage from the connection between the distribution plate 34 and the static distribution portion.

[0047] The static distribution part includes a static distribution head 35 fixedly connected to the frame 1 and an arc distribution head 36 fixedly connected to the static distribution head 35, see Fig.12 and Fig.13 The distribution static head 35 is constructed as an internal cavity structure, and a partition plate is provided inside the distribution static head 35. The internal cavity of the distribution static head 35 is divided into interval cavities 351 with different functions by the partition plate. Each interval cavity 351 is connected to an inlet pipeline 352, and the bottom of each interval cavity 351 is provided with an outlet opening 353. The arc distribution head 36 is fixedly connected to the bottom of the distribution static head 35, and can be connected by bonding or hot pressing, etc., according to actual needs. Fig.11 The other side of the arc distribution head 36 is attached to the distribution plate 34. The arc distribution head 36 is made of ceramic wear-resistant material and is provided with a lead-out through hole 361 matching the lead-out opening 353. To prevent the arc distribution head 36 from moving in the radial direction, the arc distribution head 36 is provided with a positioning protrusion 362 on the side facing the distribution plate 34, and correspondingly, the distribution plate 34 is provided with a matching positioning through hole 342.

[0048] By rotating the suction filtration cylinder 21 and the dynamic distribution part, each suction filtration housing 22 can be sequentially connected to each interval cavity 351 of the distribution static head 35. Exemplarily, the interval cavity 351 may include a feeding cavity, a washing cavity, an air drying cavity, a discharging cavity, and the like.

[0049] In this embodiment, a feed pump is used to pump material into the feed cavity. As the feed pump continues to feed at high pressure, the interior of the filter housing 22 covered by the tape body 241 is in a continuous positive pressure environment, thereby achieving the purpose of squeezing the material and removing moisture.

[0050] In order to prevent leakage of materials from the joint between the dynamic distribution part and the static distribution part under high-pressure feeding state, in this embodiment, the feeding mechanism 3 further includes a clamping member 37 for clamping the two. In this embodiment, the clamping member 37 adopts a telescopic cylinder or an air spring. The air spring can adopt the commercially available BS52020 series. The clamping member 37 is arranged on the opposite side of the distribution static head 35, which is fixedly connected to the frame 1, and the output end of the clamping member 37 is connected to the corresponding side of the distribution static head 35. The pre-tightening force of the telescopic cylinder or the air spring can ensure the sealing state between the dynamic distribution part and the static distribution part. Compared with the traditional structure using ordinary springs for sealing, the pre-tightening force is stronger and the sealing effect is better.

[0051] In order to further ensure the sealing between the arc distribution head 36 and the distribution pressure plate 34 under the positive pressure state, a packing seal 38 is also connected between the limit portion 341 of the distribution pressure plate 34 and the outer ring surface of the arc distribution head 36. The packing seal 38 is fixed by a pressure ring 39. The pressure ring 39 is sleeved on the distribution static head 35 and is tightened by bolts and other connecting parts to ensure the sealing performance of the packing seal 38. The other end of the connecting part is connected to the circumferential ear plate 354 of the distribution static head 35.

[0052] The liquid outlet mechanism 4 includes a plurality of liquid outlet pipes 41 respectively connected to the collecting chamber 226 of the suction filter housing 22, and the filtered mother liquid, washing liquid, etc. are collected and discharged through the liquid outlet pipes 41. Preferably, in order to facilitate the recovery of different types of effluent, the liquid outlet mechanism 4 also includes a liquid outlet distribution component consistent with the structural principle of the liquid inlet mechanism, which is convenient for the classification and recovery of the filtrate. Unlike the liquid inlet mechanism, the elastic member 42 can be used to achieve the compression of the dynamic distribution part and the static distribution part in the liquid outlet mechanism 4 to ensure its sealing state. The specific structure is that the ear plate 354 fixed circumferentially to the static distribution head 35 is connected to the bearing seat at this end through a screw 43, and the screw 43 is sleeved with the elastic member 42 on the side away from the dynamic distribution part. The elastic member 42 is limited by a bolt fixedly connected to the screw 43, so that it can apply a preload force in the direction of the dynamic distribution part. The elastic member 42 can be an elastic structure such as a spring or a tension spring, which can be selected according to actual needs.

[0053] For ease of understanding, the use process of the continuous high-pressure sealed filter press provided in this embodiment is introduced as an example. In this embodiment, the interval cavity 351 of the distribution static head 35 is set to include a feed cavity, a washing cavity, an air drying cavity, and a discharge cavity.

[0054] First, the material is fed from the feed cavity of the feed mechanism 3 into the cavity of the suction filter housing 22 through the feed pump. The material is continuously fed and squeezed by the pressure of the feed pump. The filtrate flows through the filter element into the inner cavity of the filter element and is discharged through the discharge mechanism.

[0055] As the suction filter cylinder 21 rotates, the corresponding suction filter housing 22 enters the next washing area, and the washing water is fed from the washing cavity of the feeding mechanism 3 into the cavity of the suction filter housing 22 through the pump. The water is continuously fed in and squeezed by the pump pressure. After the washing water washes the filter cake, it flows into the inner cavity of the filter element through the filter element and is discharged through the discharging mechanism.

[0056] As the suction filtration cylinder 21 rotates, the corresponding suction filtration housing 22 enters the next air-drying area, and the air-drying cavity is connected to gases of different pressures and temperatures to dry the filter cake;

[0057] Then it enters the unloading area not covered by the tape body 241 and unloads by back-blowing;

[0058] Finally, the unloaded suction filter housing 22 and the internal filter element are rinsed by an external washing and flushing mechanism or internal wind-blown mixed water.

[0059] The filtrate, washing liquid, etc. are discharged separately from each area through the distribution static head 35 pipeline of the discharge mechanism, which is convenient for classification and collection.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
