Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and in particular to a uniform distribution device and a belt filter press. Background Technology

[0002] Sludge with a moisture content of 80-90% after primary dewatering is in a plastic state. To meet the needs of subsequent landfill, incineration, composting, and building material utilization, it needs to undergo deep dewatering treatment to reduce the moisture content of the sludge to 60-70%. Currently, the sludge separated by existing belt filter press equipment aggregates together, making it difficult to press out the water from the center of the sludge during subsequent treatment.

[0003] Therefore, providing a device for evenly distributing water from the center of sludge and a belt filter press that facilitates subsequent treatment is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This invention discloses a uniform distribution device and a belt filter press to solve the technical problem of sludge agglomeration in belt filter presses in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a uniform distribution device, comprising:

[0007] The first drive roller has several first forming paddles spaced apart along its own axial direction, and a first feeding space is formed between any two adjacent first forming paddles.

[0008] Several unloading parts have their free ends extending into the first unloading space and abutting against the outer peripheral wall of the first drive roller; the free ends of the several unloading parts are intermittently separated from the first drive roller;

[0009] The first unloading space is configured to correspond to at least one unloading component.

[0010] In some designs, the fixed ends of several feeding components are connected to the belt filter press via mounting components.

[0011] The free ends of the mounting parts and / or the unloading parts are elastic, allowing the free ends of the unloading parts to be intermittently separated from the drive rollers.

[0012] In some designs, the mounting component has an inclined mounting portion that slopes from the proximal end toward the first drive roller.

[0013] The fixed end of the unloading part is connected to the mounting part.

[0014] In some designs, the fixed end of the unloading component is slidably connected to the mounting part, allowing the unloading component to slide toward or away from the first drive roller.

[0015] In some designs, the fixed ends of several blanking parts are provided with mounting grooves, which extend from the free end of the blanking parts to the fixed end.

[0016] The mounting section is provided with several fixing holes along the axial direction of the first drive roller, and each fixing hole corresponds to each mounting groove individually;

[0017] It also includes several connectors. When the mounting groove is aligned with the fixing hole, the connectors pass through the mounting groove and the fixing hole to achieve a sliding connection between the unloading part and the mounting part.

[0018] In some designs, the width of the mounting groove along the axial direction of the first drive roller is greater than the diameter of the connector.

[0019] In some designs, the free end of the feed piece has an inclined guide on the side opposite to the first drive roller; the guide slopes downward from the fixed end of the feed piece from its free end.

[0020] In some schemes, a second drive roller is also included, which is arranged parallel to the first drive roller; the second drive roller is provided with a number of second forming paddles at intervals along its own axial direction, and a second feeding space is formed between any two adjacent second forming paddles; the second forming paddles and the first forming paddles are arranged alternately along the axial direction of the first drive roller.

[0021] The free ends of several unloading parts extend into the second unloading space and abut against the outer peripheral wall of the second drive roller; the free ends of the unloading parts can be separated from the second drive roller intermittently.

[0022] The second feeding space is configured to correspond to at least one feeding component and one first forming paddle; the first feeding space is also configured to correspond to at least one second forming paddle.

[0023] In some designs, the outer peripheral walls of several first forming paddles and the outer peripheral walls of several second forming paddles are respectively provided with printing structures.

[0024] Secondly, the present invention also provides a belt filter press, wherein the discharge port is provided with the uniform distribution device described in the first aspect.

[0025] The technical solution adopted in this invention can achieve the following beneficial effects:

[0026] The uniform distribution device of this application forms multiple sludge strips by passing through multiple first feeding spaces. As the first drive roller rotates, the sludge strips pass through the free end of the feeding component, and the free end of the feeding component intermittently separates from and abuts against the first drive roller. During the intermittent separation and abutment process with the first drive roller, the free end of the feeding component cuts the sludge strips, realizing the automatic conveying of segmented sludge strips onto the filter belt. It also reduces the size of individual sludge strips, making it easier to filter out the water in the center of each individual sludge strip, thereby improving the dewatering effect.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0045] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0046] In the various embodiments of this application, "near end" and "far end" refer to the distance of each component from the user in the usage environment. The end closer to the user is designated as the "near end", and the end farther from the user is designated as the "far end".

[0047] The inventors discovered in actual use that the sludge separated by the existing belt filter press 200 aggregates together. In the subsequent dewatering and squeezing steps, the aggregated sludge contains a large amount of water in the cracks, which prevents the water in the cracks from being squeezed out effectively, thus affecting the sludge dewatering effect.

[0048] The following is in conjunction with the appendix Figures 1 to 13 The present application provides a detailed description of a uniform distribution device 100 and a belt filter press 200 through specific embodiments and application scenarios.

[0049] The uniform distribution device 100 provided in some embodiments of this application, such as Figure 1 and Figure 3 As shown, it includes a first drive roller 110 and several feeding components 170.

[0050] like Figure 1 and Figure 3 As shown, the first drive roller 110 is provided with a plurality of first forming paddles 120 spaced apart along its own axial direction, and a first feeding space 140 is formed between any two adjacent first forming paddles 120. During the sludge feeding process, the plurality of first feeding spaces 140 are the main channels for sludge feeding. As the first drive roller 110 rotates, the sludge is carried into the plurality of first feeding spaces 140 and gradually forms sludge strips, ensuring that the sludge can be transported stably and continuously, and avoiding sludge blockage and accumulation during the transportation process.

[0051] like Figure 3 As shown, several unloading parts 170 are arranged in a row, with their free ends extending into the first unloading space 140 and abutting against the outer peripheral wall of the first transmission roller 110. The free ends of the unloading parts 170 can be separated from the first transmission roller 110 intermittently.

[0052] As the first drive roller 110 rotates, the sludge strips pass through the free end of the feeder 170. The free end of the feeder 170 intermittently separates from and contacts the first drive roller 110. During the intermittent separation and contact with the first drive roller 110, the free end of the feeder 170 cuts the sludge strips, realizing the automatic conveying of segmented sludge strips onto the filter belt. This also reduces the size of individual sludge strips, making it easier to filter out the water in the center of each individual sludge strip, thereby improving the dewatering effect.

[0053] In some embodiments, a first feeding space 140 is correspondingly provided with a feeding member 170. In this embodiment, the feeding member 170 has a gap D2 between its two sidewalls along the axial direction of the first drive roller 110 and the opposing sidewalls of the two first forming paddles 120.

[0054] In some embodiments, a first feeding space 140 is correspondingly provided with a plurality of feeding components 170. In this embodiment, the opposite sidewalls of the two outermost feeding components 170 along the axial direction of the first drive roller 110 have a gap D2 between them and the opposing sidewalls of the two first forming paddles 120.

[0055] During the rotation of the first drive roller 110, as... Figure 9 and Figure 10 As shown, due to the presence of gap D2, the unloading part 170 and the first forming paddle 120 will not rub against each other, will not affect the rotation of the first transmission roller 110, and will not cause unnecessary wear between the unloading part 170 and the first forming paddle 120.

[0056] like Figure 1 and Figure 3 As shown, it also includes a second transmission roller 111 arranged parallel to the first transmission roller 110. The second transmission roller 111 is provided with a plurality of second forming paddles 130 spaced apart along its own axial direction, and a second feeding space 150 is formed between any two adjacent second forming paddles 130.

[0057] Similar to the first feeding space 140, the second feeding space 150 is also the main channel for sludge feeding. As the second drive roller 111 rotates, the sludge is also carried into multiple second feeding spaces 150 and gradually forms sludge strips, which further ensures that the sludge can be transported stably and continuously, and avoids sludge blockage and accumulation during the transportation process.

[0058] like Figure 1 , Figure 3 , Figure 8 , Figure 11 and Figure 12 As shown, a plurality of second forming paddles 130 and a plurality of first forming paddles 120 are alternately arranged along the axial direction of the first drive roller 110. During the process of sludge being fed through the first feeding space 140 and the second feeding space 150, the sludge comes into contact with the first forming paddles 120 and the second forming paddles 130, and is evenly distributed on the first forming paddles 120 and the second forming paddles 130 as the first forming paddles 120 and the second forming paddles 130 rotate, thereby providing better adhesion and friction, which is beneficial to the stable conveying of sludge on the first drive roller 110 and the second drive roller 111, and further prevents sludge from slipping or clogging during the conveying process.

[0059] Correspondingly, such as Figure 1 , Figure 3 and Figure 6As shown, several unloading parts 170 are arranged in a second row, with their free ends extending into the second unloading space 150 and abutting against the outer peripheral wall of the second drive roller 111. The free ends of the unloading parts 170 can be intermittently separated from the second drive roller 111. The principle of the intermittent separation of the free ends of the unloading parts 170 from the second drive roller 111 is the same as the function of the intermittent separation of the free ends of the unloading parts 170 from the first drive roller 110, and will not be elaborated here.

[0060] It should be noted that the correspondence and setting of the second feeding space 150 and the feeding part 170 are the same as those of the first feeding space 140 and the feeding part 170, and will not be repeated here.

[0061] In this embodiment, when the first drive roller 110 and the second drive roller 111 are used in the belt filter press 200, the belt filter press 200 is further provided with a drive mechanism to drive the first drive roller 110 and the second drive roller 111 to rotate in opposite directions around their own axis. The drive mechanism can be a combination of a motor and gears, or a combination of two motors and two filter belt pulleys, or other methods; this embodiment does not limit this.

[0062] In this embodiment, as Figure 1 and Figure 3 As shown, the first forming paddle 120 and the second forming paddle 130 are preferably cylindrical and have a certain thickness, so that the sludge can be well attached to the outer peripheral walls of the first forming paddle 120 and the second forming paddle 130.

[0063] In this embodiment, the lengths of the first feeding space 140 and the second feeding space 150 along the axial direction of the first transmission roller 110 can be changed by adjusting the gap D1 between two adjacent first forming paddles 120 and the gap D1 between two adjacent second forming paddles 130 to adapt to different sludge feeding requirements.

[0064] In this embodiment, as Figure 1 and Figure 3 As shown, the first forming paddle 120 and the second forming paddle 130 at the ends of the first drive roller 110 and the second drive roller 111 are thickened or thinned according to the lengths of the first drive roller 110 and the second drive roller 111, the length of the first feeding space 140 along the axial direction of the first drive roller 110, and the length of the second feeding space 150 along the axial direction of the first drive roller 110. This allows the first feeding space 140 and the second feeding space 150 to be formed at both ends of the first drive roller 110 and the second drive roller 111, so that the sludge passing through both ends of the first drive roller 110 and the second drive roller 111 can be transported stably and continuously.

[0065] In some embodiments, a plurality of first feeding spaces 140 have the same length along the axial direction of the first drive roller 110, a plurality of second feeding spaces 150 have the same length along the axial direction of the first drive roller 110, and the lengths of the first feeding spaces 140 and the second feeding spaces 150 along the axial direction of the first drive roller 110 are different.

[0066] In some embodiments, a plurality of first feeding spaces 140 have the same length along the axial direction of the first drive roller 110, and a plurality of second feeding spaces 150 have the same length along the axial direction of the first drive roller 110 as the first feeding spaces 140 have the same length along the axial direction of the first drive roller 110.

[0067] In some embodiments, the lengths of the first feeding spaces 140 along the axial direction of the first drive roller 110 are different, and the lengths of the second feeding spaces 150 along the axial direction of the first drive roller 110 are also different.

[0068] All three embodiments described above can achieve sludge feeding. In this embodiment, it is preferable to use a plurality of first feeding spaces 140 with the same length along the axial direction of the first drive roller 110, and a plurality of second feeding spaces 150 with the same length along the axial direction of the first drive roller 110 as the first feeding spaces 140 with the same length along the axial direction of the first drive roller 110, so as to ensure that the shape and size of the fed sludge are the same, so as to better compress the sludge in subsequent steps.

[0069] like Figure 1 , Figure 3 , Figure 8 , Figure 11 and Figure 12 As shown, the first feeding space 140 is correspondingly arranged with at least one second forming paddle 130, and the second feeding space 150 is correspondingly arranged with at least one first forming paddle 120. During the feeding process, the sludge that comes into contact with the first forming paddles 120 is evenly distributed on the outer peripheral wall of the first forming paddles 120 and passes through the second feeding spaces 150; the sludge that comes into contact with the second forming paddles 130 is evenly distributed on the outer peripheral wall of the second forming paddles 130 and passes through the first feeding spaces 140. By adopting the method of corresponding the first feeding space 140 with the second forming paddle 130 and the second feeding space 150 with the first forming paddle 120, the throughput of sludge per pass can be increased, allowing the sludge to form sludge strips. This ensures stable and continuous sludge transportation and avoids sludge blockage and accumulation during transportation.

[0070] In some embodiments, such as Figure 8 As shown, a first feeding space 140 is correspondingly set with a second forming paddle 130, and a second feeding space 150 is correspondingly set with a first forming paddle 120.

[0071] In some embodiments, such as Figure 12 As shown, a first feeding space 140 is correspondingly arranged with a second forming paddle 130; multiple first forming paddles 120 form a first forming paddle 120 group, and a second feeding space 150 is correspondingly arranged with a first forming paddle 120 group. At this time, the first feeding space 140 is the space formed by two adjacent first forming paddle 120 groups.

[0072] In some embodiments, such as Figure 11 As shown, multiple second forming paddles 130 form a group of second forming paddles 130, and a first feeding space 140 is correspondingly set with one group of second forming paddles 130; a second feeding space 150 is correspondingly set with one first forming paddle 120. At this time, the second feeding space 150 is the space formed by the group of second forming paddles 130.

[0073] Through the above three embodiments, the cooperation between the first feeding space 140 and the second forming paddle 130, and between the second feeding space 150 and the first forming paddle 120 can be achieved. In this embodiment, it is preferable to adopt a configuration where one first feeding space 140 is correspondingly arranged with one second forming paddle 130, and one second feeding space 150 is correspondingly arranged with one first forming paddle 120, which further ensures that the sludge can be transported stably and continuously.

[0074] like Figure 8 , Figure 11 and Figure 12 As shown, the length of the first feeding space 140 along the axial direction of the first transmission roller 110 is equal to the sum of the lengths of the corresponding second forming paddles 130 along the axial direction of the first transmission roller 110; the length of the second feeding space 150 along the axial direction of the first transmission roller 110 is equal to the sum of the lengths of the corresponding first forming paddles 120 along the axial direction of the first transmission roller 110.

[0075] In the above manner, during the sludge feeding process, it can be ensured that the sludge can be uniformly deformed and shaped under the action of the first forming paddle 120 and the second feeding space 150, the second forming paddle 130 and the first feeding space 140, which is more conducive to turning the sludge into strip-shaped sludge strips.

[0076] like Figure 6 As shown, there is a gap D1 between the orthographic projection of a plurality of first forming paddles 120 along the axial direction of the first drive roller 110 and the orthographic projection of a plurality of second forming paddles 130 along the axial direction of the first drive roller 110.

[0077] Due to the presence of gap D1, the two sidewalls of the first forming paddle 120 along the axial direction of the first drive roller 110 will not come into contact with the two opposing sidewalls of the two second forming paddles 130 along the axial direction of the first drive roller 110; similarly, the two sidewalls of the second forming paddle 130 along the axial direction of the first drive roller 110 will not come into contact with the two opposing sidewalls of the two first forming paddles 120 along the axial direction of the first drive roller 110. This ensures that the sludge can be uniformly deformed and formed into sludge strips, while also preventing the first forming paddle 120 and the second forming paddle 130 from coming into contact, thus not affecting the rotation of the first drive roller 110 and the second drive roller 111. Furthermore, it prevents unnecessary wear between the first forming paddle 120 and the second forming paddle 130.

[0078] like Figure 1 and Figure 3 As shown, the outer peripheral walls of several first forming paddles 120 and several second forming paddles 130 are respectively provided with printing structures 160. During the process of sludge passing through the first feeding space 140 and the second feeding space 150, the outer peripheral walls of the first forming paddles 120 and the second forming paddles 130 respectively compress the sludge. During the compression process, the printing structures 160 come into contact with the sludge, and the surface of the compressed sludge strip forms protrusions corresponding to the shape of the printing structures 160, increasing the surface area of ​​the sludge strip and thus facilitating better compression of the sludge for water extraction.

[0079] In this embodiment, the printing structure 160 is formed by a plurality of intersecting inclined grooves. Naturally, the printing structure 160 can also be other shapes, and this embodiment does not limit this.

[0080] like Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, when the first drive roller 110 and the second drive roller 111 are installed on the belt filter press 200, the fixed ends of several feeding components 170 are respectively connected to the belt filter press 200 through mounting components 180. The mounting components 180 are used to provide a mounting base for the several feeding components 170, so that the feeding components 170 can be connected to the belt filter press 200.

[0081] The free ends of the mounting component 180 and / or the feeding component 170 are elastic, allowing the free ends of the feeding component 170 to intermittently separate from the first drive roller 110 and the second drive roller 111. Initially, the free ends of the feeding component 170 abut against the outer peripheral walls of the first drive roller 110 and the second drive roller 111. As the first drive roller 110 and the second drive roller 111 rotate, due to the elasticity of the mounting component 180 and / or the free ends of the feeding component 170, the free ends of the feeding component 170 vibrate. During this vibration, the free ends of the feeding component 170 intermittently separate from and abut against the first drive roller 110 and the second drive roller 111. Furthermore, during this vibration, the free ends of the feeding component 170 cut the sludge strips into multiple sludge segments.

[0082] In some embodiments, the mounting member 180 is elastic. As the first drive roller 110 and the second drive roller 111 rotate, the mounting member 180 intermittently stores and releases elastic potential energy, causing the free end of the unloading member 170 to vibrate.

[0083] In some embodiments, the free end of the feeder 170 is elastic. As the first drive roller 110 and the second drive roller 111 rotate, the free end of the feeder 170 intermittently stores and releases elastic potential energy, causing the free end of the feeder 170 to vibrate.

[0084] In some embodiments, the free ends of the mounting member 180 and the unloading member 170 are both elastic. As the first drive roller 110 and the second drive roller 111 rotate, the free ends of the mounting member 180 and the unloading member 170 intermittently store and release elastic potential energy, causing the free end of the unloading member 170 to vibrate.

[0085] In an embodiment where the mounting member 180 is resilient, the mounting member 180 is a sheet metal part, with a bending structure 181 in its middle, such as... Figure 7 As shown. Due to the presence of the bending structure 181, the distal end of the mounting part 180 is subjected to force and transmitted to the bending structure 181, causing the bending structure 181 to deform and bend downwards, thereby separating the free end of the unloading part 170 from the outer peripheral wall of the transmission roller. When the external force is removed, the bending structure 181 recovers its deformation, thereby causing the free end of the unloading part 170 to contact the outer peripheral walls of the first transmission roller 110 and the second transmission roller 111.

[0086] like Figure 7 As shown, the mounting member 180 has an inclined mounting portion 182, which is inclined from the proximal end toward the first drive roller 110; the fixed end of the unloading member 170 is connected to the mounting portion 182.

[0087] When the unloading part 170 is connected to the mounting part 182, the unloading part 170 is in an inclined state, so that the free end of the unloading part 170 can better abut against the first transmission roller 110 and the second transmission roller 111.

[0088] like Figure 2 As shown, the fixed end of the unloading component 170 is slidably connected to the mounting part 182, allowing the unloading component 170 to slide towards or away from the first transmission roller 110 / second transmission roller 111. The position of the unloading component 170 can be changed by sliding it. In the initial design, it is not necessary to precisely design parameters such as the dimensions of the unloading component 170, the distance between the mounting point of the fixed end of the unloading component 170 on the mounting part 182 and the contact point between the free end of the unloading component 170 and the first transmission roller 110 / second transmission roller. During equipment debugging, it is only necessary to slide the unloading component 170 so that its free end abuts against the outer peripheral wall of the first transmission roller 110 and the second transmission roller 111, saving time and effort.

[0089] Specifically, such as Figure 2 and Figure 7 As shown, the fixed end of the unloading component 170 is provided with a mounting groove 171, which extends from the free end of the unloading component 170 to the fixed end. The mounting part 182 is provided with a plurality of fixing holes along the axial direction of the first transmission roller 110, and each fixing hole corresponds to each mounting groove 171 individually. When the mounting groove 171 is aligned with the fixing hole, the connecting member passes through the mounting groove 171 and the fixing hole to achieve a sliding connection between the unloading component 170 and the mounting part 180.

[0090] In a preferred embodiment, the connector includes a bolt 172, a washer 173, and a nut 175. The threaded end of the bolt 172 passes sequentially through the washer 173, the mounting groove 171, and the fixing hole, and is tightened by the nut 175. The head of the bolt 172 presses the washer 173 tightly against the top of the blanking part 170, and the washer 173 effectively prevents the bolt 172 from loosening. Correspondingly, by loosening the nut 175, the blanking part 170 can slide on the mounting part 182.

[0091] Naturally, the connector can also be of other structures, and this embodiment does not limit this.

[0092] like Figure 2 As shown, the width of the mounting groove 171 along the axial direction of the first drive roller 110 is greater than the diameter of the connector. With this configuration, when the unloading part 170 is mounted on the mounting part 182 via the connector, the angle of the unloading part 170 can be finely adjusted so that the unloading part 170 can better abut against the first drive roller 110 and the second drive roller 111.

[0093] In some embodiments, the fixed ends of a plurality of feeding components 170 are slidably connected to the mounting portion 182, and the length of each feeding component 170 extending into the first feeding space 140 or the second feeding space 150 can be adjusted individually.

[0094] In some embodiments, after the fixed ends of a plurality of unloading parts 170 are fixedly connected, they are slidably connected to the mounting part 182, and the length of each row of unloading parts 170 extending into the first unloading space 140 or the second unloading space 150 is adjusted synchronously.

[0095] like Figure 4 and Figure 5 As shown, the free end of the feeder 170 has an inclined guide portion 174 on the side opposite to the first drive roller 110 / second drive roller 111. The guide portion 174 slopes downward from the fixed end of the feeder 170 from its free end. Due to the presence of the guide portion 174, as the first forming paddle 120 and the second forming paddle 130 carry the sludge strip past the free end of the feeder 170, the sludge strip separates from the first forming paddle 120 and the second forming paddle 130 under the action of the guide portion 174, and forms sludge strip segments with the vibration of the free end of the feeder 170.

[0096] It should be noted that the thickness of the free end face of the feeder 170 should be as small as possible. If the thickness of the free end face of the feeder 170 is too large, the sludge strip will accumulate at the end face of the free end of the feeder 170 as the first forming paddle 120 and the second forming paddle 130 carry the sludge strip through it, preventing the sludge strip from effectively separating from the first forming paddle 120 and the second forming paddle 130.

[0097] like Figure 1 , Figure 3 and Figure 6 As shown, the diameters of the first forming paddles 120 and the second forming paddles 130 are the same, thereby ensuring that the sludge passing through the first feeding space 140 and the sludge passing through the second feeding space 150 are compressed to the same degree, so as to facilitate the dewatering of the sludge segments in subsequent processes.

[0098] like Figure 1 , Figure 3 and Figure 6As shown, when the first drive roller 110 and the second drive roller 111 are used in the belt filter press 200, the two rows of feed members 170 are located on opposite sides of the first drive roller 110 and the second drive roller 111. When the first drive roller 110 and the second drive roller 111 are used in the belt filter press 200, the first drive roller 110 and the second drive roller 111 rotate towards each other, and the feed area is located in the middle position of the first drive roller 110 and the second drive roller 111. Therefore, by setting the two rows of feed members 170 on opposite sides of the first drive roller 110 and the second drive roller 111, the feed of the sludge strips is not affected.

[0099] The belt filter press 200 provided in some embodiments of this application, such as Figure 13 As shown, the discharge port is equipped with the aforementioned uniform distribution device 100.

[0100] In this embodiment, the discharge port is located at the bottom of the belt filter press 200, and a filter belt is also provided below the discharge port to realize the automatic conveying of sludge segments.
