[0006] In some schemes, the fixed ends of several feeding members are respectively connected to the belt filter press equipment through mounting members; The free end of the mounting piece and / or the blanking piece is elastic, so that the free end of the blanking piece can be separated from the driving roller intermittently.

When the mounting groove is aligned with the fixing hole, the connecting pieces pass through the mounting groove and the fixing hole to realize the sliding connection between the blanking piece and the mounting piece.

[0010] In some embodiments, the width of the mounting groove along the axial direction of the first transmission roller is greater than the diameter of the connecting member.

[0011] In some schemes, a side of the free end of the blanking piece facing away from the first driving roller has an inclined guide portion; the guide portion is inclined downward from the free end of the blanking piece from the fixed end of the blanking piece.

DETAILED DESCRIPTION

[0019] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0020] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0022] The inventors found in actual use that the sludge separated by the existing belt filter press 200 gathered together. In the subsequent dehydration and extrusion step, the sludge gathered together contained a large amount of water in the cracks, resulting in the water contained in the cracks not being squeezed out well, thereby affecting the sludge dehydration effect.

[0023] The following is combined with Figures 1 to 13 , a uniform distribution device 100 and a belt filter press equipment 200 provided in the present application are described in detail through specific embodiments and their application scenarios.

[0024] The uniform distribution device 100 provided in some embodiments of the present application is as follows: Figure 1 and Figure 3 As shown, it includes a first transmission roller 110 and a plurality of blanking parts 170 .

[0025] like Figure 1 and Figure 3As shown, the first driving roller 110 is provided with a plurality of first forming paddles 120 at intervals along its axial direction, and a first material discharge space 140 is formed between any two adjacent first forming paddles 120. During the sludge discharge process, the plurality of first material discharge spaces 140 are the main channels for sludge discharge. With the rotation of the first driving roller 110, the sludge is brought into the plurality of first material discharge spaces 140 and gradually forms sludge strips, thereby ensuring that the sludge can be transported stably and continuously, and avoiding blockage and accumulation of the sludge during the transportation process.

[0026] like Figure 3 As shown, a plurality of blanking pieces 170 are arranged in a row, and the free ends extend into the first blanking space 140 and abut against the outer peripheral wall of the first driving roller 110 . The free ends of the blanking pieces 170 can be intermittently separated from the first driving roller 110 .

[0027] As the first drive roller 110 rotates, the sludge strips will pass through the free end of the discharge piece 170, and the free end of the discharge piece 170 will be intermittently separated from and abutted against the first drive roller 110. In the process of intermittently separating from and abutting against the first drive roller 110, the free end of the discharge piece 170 will cut off the sludge strips, thereby automatically conveying segmented sludge strips to the filter belt, and reducing the size of a single sludge strip segment, so that the water in the center of a single sludge strip segment can be more easily filtered out, thereby improving the dehydration effect.

[0028] In some embodiments, a first material removal space 140 is disposed correspondingly to a material removal piece 170. In this embodiment, a gap D2 is formed between two side walls of the material removal piece 170 along the axial direction of the first driving roller 110 and the opposite side walls of the two first forming paddles 120, respectively.

[0029] In some embodiments, a first material removal space 140 is provided corresponding to a plurality of material removal pieces 170. In this embodiment, there are gaps D2 between the opposite side walls of the two outermost material removal pieces 170 along the axial direction of the first driving roller 110 and the opposite side walls of the two first forming paddles 120, respectively.

[0030] During the rotation of the first transmission roller 110, Fig. 9 and Fig.10 As shown, due to the existence of the gap D2, no friction will be generated between the blanking piece 170 and the first forming paddle 120, which will not affect the rotation of the first driving roller 110 and will not cause unnecessary wear between the blanking piece 170 and the first forming paddle 120.

[0031] like Figure 1 and Figure 3 As shown, it also includes a second driving roller 111 arranged in parallel with the first driving roller 110 , and the second driving roller 111 is provided with a plurality of second forming paddles 130 at intervals along its axial direction, and a second material discharge space 150 is formed between any two adjacent second forming paddles 130 .

[0032] Similar to the first unloading space 140, the second unloading space 150 is also the main channel for sludge unloading. As the second transmission roller 111 rotates, the sludge is also brought into multiple second unloading spaces 150 and gradually forms sludge strips, further ensuring that the sludge can be transported stably and continuously, and avoiding blockage and accumulation of sludge during transportation.

[0033] like Figure 1 , Figure 3 , Figure 8 , Fig.11 and Fig.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 driving roller 110. In the process of sludge feeding through the first feeding space 140 and the second feeding space 150, the sludge contacts the first forming paddle 120 and the second forming paddle 130, and is evenly distributed on the first forming paddle 120 and the second forming paddle 130 as the first forming paddle 120 and the second forming paddle 130 rotate, thereby providing better adhesion and friction, facilitating the stable conveyance of the sludge on the first driving roller 110 and the second driving roller 111, and further preventing the sludge from slipping or clogging during the conveyance process.

[0034] Correspondingly, such as Figure 1 , Figure 3 and Figure 6 As shown, a plurality of blanking pieces 170 are further arranged in a second row, with the free ends extending into the second blanking space 150 and abutting against the outer peripheral wall of the second driving roller 111, and the free ends of the blanking pieces 170 can be intermittently separated from the second driving roller 111. The principle of the intermittent separation of the free ends of the blanking pieces 170 from the second driving roller 111 is the same as the function of the intermittent separation of the free ends of the blanking pieces 170 from the first driving roller 110, and will not be described in detail here.

[0035] It should be noted that the correspondence and arrangement of the second material removal space 150 and the material removal piece 170 are the same as the correspondence and arrangement of the first material removal space 140 and the material removal piece 170, and will not be repeated here.

[0036] In this embodiment, when the first transmission roller 110 and the second transmission roller 111 are used in the belt filter press 200, a driving mechanism is further provided on the belt filter press 200 to drive the first transmission roller 110 and the second transmission roller 111 to rotate toward each other around their own rotation axes. The driving mechanism can be a motor and a gear, or two motors and two filter belt wheels, or other methods, which are not limited in this embodiment.

[0037] In this embodiment, if Figure 1 and Figure 3As shown, the first shaping paddle 120 and the second shaping paddle 130 are preferably cylindrical and have a certain thickness, so that the outer peripheral walls of the first shaping paddle 120 and the second shaping paddle 130 can be well attached to the sludge.

[0038] In this embodiment, the axial lengths of the first unloading space 140 and the second unloading space 150 in the first driving 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 meet different sludge unloading requirements.

[0039] In this embodiment, if Figure 1 and Figure 3 As shown, the first forming paddle 120 and the second forming paddle 130 at the end of the first drive roller 110 and the end of the second drive roller 111 are correspondingly thickened or thinned according to the length of the first drive roller 110 and the second drive roller 111, the length of the first unloading space 140 along the axial direction of the first drive roller 110, and the length of the second unloading space 150 along the axial direction of the first drive roller 110, so that the first drive roller 110 and the second drive roller 111 can also form the first unloading space 140 and the second unloading space 150 at both ends, so that the sludge passing through both ends of the first drive roller 110 and the second drive roller 111 can also be stably and continuously transported.

[0040] In some embodiments, several first unloading spaces 140 have the same length along the axial direction of the first transmission roller 110, several second unloading spaces 150 have the same length along the axial direction of the first transmission roller 110, and the first unloading spaces 140 and the second unloading spaces 150 have different lengths along the axial direction of the first transmission roller 110.

[0041] In some embodiments, the lengths of the first material unloading spaces 140 along the axial direction of the first transmission roller 110 are the same, and the lengths of the second material unloading spaces 150 along the axial direction of the first transmission roller 110 are the same as the length of the first material unloading spaces 140 along the axial direction of the first transmission roller 110 .

[0042] In some embodiments, the lengths of the plurality of first material unloading spaces 140 along the axial direction of the first transmission roller 110 are different, and the lengths of the plurality of second material unloading spaces 150 along the axial direction of the first transmission roller 110 are also different.

[0043] The above three embodiments can all realize the discharge of sludge. In this embodiment, it is preferred that the lengths of the first discharge spaces 140 along the axial direction of the first transmission roller 110 are the same, and the lengths of the second discharge spaces 150 along the axial direction of the first transmission roller 110 are the same as the lengths of the first discharge spaces 140 along the axial direction of the first transmission roller 110, so as to ensure that the discharged sludge has the same shape and size, so as to better squeeze the sludge in the subsequent steps.

[0044] like Figure 1 , Figure 3 , Figure 8 , Fig.11 and Fig.12 As shown, the first unloading space 140 is arranged corresponding to at least one second forming paddle 130, and the second unloading space 150 is arranged corresponding to at least one first forming paddle 120. During the unloading process of sludge, the sludge in 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 unloading spaces 150; the sludge in 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 unloading spaces 140. By adopting the method of correspondingly arranging the first unloading space 140 with the second forming paddle 130 and correspondingly arranging the second unloading space 150 with the first forming paddle 120, the single passing amount of sludge can be increased, so that the sludge forms sludge strips, which not only ensures the stable and continuous transportation of sludge, but also avoids the blockage and accumulation of sludge during the transportation process.

[0045] In some embodiments, Figure 8 As shown, a first material discharge space 140 is provided corresponding to a second forming paddle 130 , and a second material discharge space 150 is provided corresponding to a first forming paddle 120 .

[0046] In some embodiments, Fig.12 As shown, a first material unloading space 140 is provided corresponding to a second forming paddle 130; a plurality of first forming paddles 120 form a first forming paddle 120 group, and a second material unloading space 150 is provided corresponding to a first forming paddle 120 group. At this time, the first material unloading space 140 is a space formed by two adjacent first forming paddle 120 groups.

[0047] In some embodiments, Fig.11 As shown, a plurality of second forming paddles 130 form a second forming paddle 130 group, a first unloading space 140 is correspondingly arranged with a second forming paddle 130 group; a second unloading space 150 is correspondingly arranged with a first forming paddle 120. At this time, the second unloading space 150 is the space formed by the second forming paddle 130 group.

[0048] Through the above three embodiments, the first unloading space 140 and the second forming paddle 130, and the second unloading space 150 and the first forming paddle 120 can be matched. In this embodiment, one first unloading space 140 is correspondingly arranged with one second forming paddle 130, and one second unloading space 150 is correspondingly arranged with one first forming paddle 120, which further ensures that the sludge can be transported stably and continuously.

[0049] like Figure 8 , Fig.11 and Fig.12 As shown, the axial length of the first unloading space 140 in the first driving roller 110 is equal to the sum of the axial lengths of the corresponding second forming paddles 130 in the first driving roller 110; the axial length of the second unloading space 150 in the first driving roller 110 is equal to the sum of the axial lengths of the corresponding first forming paddles 120 in the first driving roller 110.

[0050] By means of the above method, during the sludge feeding process, it can be ensured that the sludge can be uniformly deformed and formed 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 transforming the sludge into strip-shaped sludge strips.

[0051] like Figure 6 As shown, there is a gap D1 between the orthographic projections of the plurality of first forming paddles 120 along the axial direction of the first transmission roller 110 and the orthographic projections of the plurality of second forming paddles 130 along the axial direction of the first transmission roller 110 .

[0052] Due to the existence of the gap D1, the two side walls of the first forming paddle 120 along the axial direction of the first transmission roller 110 will not come into contact with the two opposite side walls of the two second forming paddles 130 along the axial direction of the first transmission roller 110; the two side walls of the second forming paddle 130 along the axial direction of the first transmission roller 110 will not come into contact with the two opposite side walls of the two first forming paddles 120 along the axial direction of the first transmission roller 110. While ensuring that the sludge can be uniformly deformed and formed into sludge strips, the first forming paddle 120 and the second forming paddle 130 will not come into contact, thereby not affecting the rotation of the first transmission roller 110 and the second transmission roller 111, and at the same time, unnecessary wear will not occur between the first forming paddle 120 and the second forming paddle 130.

[0053] like Figure 1 and Figure 3 As shown, the outer peripheral walls of the first forming paddles 120 and the outer peripheral walls of the second forming paddles 130 are respectively provided with a printing structure 160. When the sludge passes through the first material discharge space 140 and the second material discharge space 150, the outer peripheral walls of the first forming paddles 120 and the outer peripheral walls of the second forming paddles 130 squeeze the sludge respectively. During the squeezing process, the printing structure 160 contacts the sludge, and the surface of the squeezed sludge strip forms a protrusion with a shape corresponding to the printing structure 160, which increases the surface area of ​​the sludge strip, thereby facilitating better squeezing of the sludge out of the water.

[0054] In this embodiment, the printed structure 160 is formed by staggering a plurality of inclined grooves. Of course, the printed structure 160 can also be in other shapes, which is not limited in this embodiment.

[0055] like Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, when the first driving roller 110 and the second driving roller 111 are installed on the belt filter press 200, the fixed ends of the plurality of material discharge members 170 are respectively connected to the belt filter press 200 through the mounting members 180. The mounting members 180 are used to provide a mounting base for the plurality of material discharge members 170 so that the material discharge members 170 can be connected to the belt filter press 200.

[0056] The free ends of the mounting member 180 and / or the blanking member 170 are elastic, so that the free ends of the blanking member 170 can be intermittently separated from the first transmission roller 110 and the second transmission roller 111. In the initial state, the free ends of the blanking member 170 abut against the outer peripheral walls of the first transmission roller 110 and the second transmission roller 111. As the first transmission roller 110 and the second transmission roller 111 rotate, the free ends of the blanking member 170 will vibrate due to the elasticity of the free ends of the mounting member 180 and / or the blanking member 170. During the vibration, the free ends of the blanking member 170 are intermittently separated from and abut against the first transmission roller 110 and the second transmission roller 111. In addition, during the vibration, the free ends of the blanking member 170 will cut the sludge strip into multiple sludge strip segments.

[0057] In some embodiments, the mounting member 180 is elastic. As the first transmission roller 110 and the second transmission roller 111 rotate, the mounting member 180 intermittently stores and releases elastic potential energy, so that the free end of the blanking member 170 vibrates.

[0058] In some embodiments, the free end of the blanking member 170 is elastic. As the first transmission roller 110 and the second transmission roller 111 rotate, the free end of the blanking member 170 intermittently stores and releases elastic potential energy, causing the free end of the blanking member 170 to vibrate.

[0059] In some embodiments, the free ends of the mounting member 180 and the blanking member 170 are elastic. As the first transmission roller 110 and the second transmission roller 111 rotate, the free ends of the mounting member 180 and the blanking member 170 intermittently store and release elastic potential energy, causing the free end of the blanking member 170 to vibrate.

[0060] In the embodiment where the mounting member 180 is elastic, the mounting member 180 is a sheet metal member, and the middle portion thereof has a bending structure 181, such as Figure 7As shown. Due to the existence of the bending structure 181, the distal end of the mounting member 180 is subjected to force and transmitted to the bending structure 181, so that the bending structure 181 can be deformed and bent downward, thereby separating the free end of the blanking member 170 from the outer peripheral wall of the driving roller. When the external force is removed, the bending structure 181 is deformed and restored, thereby making the free end of the blanking member 170 contact the outer peripheral wall of the first driving roller 110 and the second driving roller 111.

[0061] like Figure 7 As shown, the mounting member 180 has an inclined mounting portion 182 , and the mounting portion 182 is inclined from the proximal end to the distal end toward the first transmission roller 110 ; the fixed end of the blanking member 170 is connected to the mounting portion 182 .

[0062] The mounting portion 182 is tilted, and when the lower material piece 170 is connected to the mounting portion 182 , the lower material piece 170 is tilted, so that the free end of the lower material piece 170 can better abut against the first transmission roller 110 and the second transmission roller 111 .

[0063] like Figure 2 As shown, the fixed end of the blanking piece 170 is slidably connected to the mounting portion 182, so that the blanking piece 170 can slide toward or away from the first transmission roller 110 / the second transmission roller 111. The position of the blanking piece 170 can be changed by sliding the blanking piece 170. In the early design, it is not necessary to accurately design parameters such as the size of the blanking piece 170, the distance between the mounting point of the fixed end of the blanking piece 170 on the mounting portion 182 and the abutment point of the free end of the blanking piece 170 on the first transmission roller 110 / the second transmission roller. When debugging the equipment, it is only necessary to slide the blanking piece 170 so that the free end of the blanking piece 170 abuts against the outer peripheral wall of the first transmission roller 110 and the second transmission roller 111, which saves time and effort.

[0064] Specifically, Figure 2 and Figure 7 As shown, the fixed end of the blanking piece 170 is provided with a mounting groove 171, and the mounting groove 171 extends from the free end to the fixed end of the blanking piece 170. The mounting portion 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. 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 realize the sliding connection between the blanking piece 170 and the mounting piece 180.

[0065] As a preferred embodiment of the present invention, the connecting member includes a bolt 172, a washer 173 and a nut 175. The threaded end of the bolt 172 passes through the washer 173, the mounting groove 171 and the fixing hole in sequence, and is tightened by the nut 175; the head of the bolt 172 presses the washer 173 tightly against the top of the blanking member 170, and the washer 173 can well prevent the bolt 172 from loosening. Accordingly, by loosening the nut 175, the blanking member 170 can slide on the mounting portion 182.

[0066] Of course, the connecting piece may also be other structures, which is not limited in this embodiment.

[0067] like Figure 2 As shown, the width of the mounting groove 171 along the axial direction of the first transmission roller 110 is greater than the diameter of the connecting piece. With such a configuration, when the lower material 170 is mounted on the mounting portion 182 through the connecting piece, the angle of the lower material 170 can be fine-tuned so that the lower material 170 can better abut against the first transmission roller 110 and the second transmission roller 111.

[0068] In some embodiments, the fixed ends of the plurality of blanking members 170 are respectively slidably connected to the mounting portion 182 , and the length of each blanking member 170 extending into the first blanking space 140 or the second blanking space 150 can be adjusted individually.

[0069] In some embodiments, the fixed ends of several blanking pieces 170 are fixedly connected and then slidably connected to the mounting portion 182, and the length of each row of blanking pieces 170 extending into the first blanking space 140 or the second blanking space 150 is synchronously adjusted.

[0070] like Figure 4 and Figure 5 As shown, the free end of the material discharging member 170 is provided with an inclined guide portion 174 on the side away from the first driving roller 110 / the second driving roller 111, and the guide portion 174 is inclined downward from the fixed end of the material discharging member 170 from the free end of the material discharging member 170. Due to the existence of the guide portion 174, when the first forming paddle 120 and the second forming paddle 130 carry the sludge strips through the free end of the material discharging member 170, the sludge strips will be separated from the first forming paddle 120 and the second forming paddle 130 under the action of the guide portion 174, and will be formed into sludge strip segments as the free end of the material discharging member 170 vibrates.

[0071] It should be noted that the thickness of the end surface of the free end of the blanking member 170 should be as small as possible. If the thickness of the end surface of the free end of the blanking member 170 is too large, the sludge strips will accumulate on the end surface of the free end of the blanking member 170 when the first forming paddle 120 and the second forming paddle 130 carry the sludge strips through the free end of the blanking member 170, resulting in the sludge strips being unable to be effectively separated from the first forming paddle 120 and the second forming paddle 130.

[0072] like Figure 1 , Figure 3 and Figure 6 As shown, the diameter of the first forming paddles 120 is the same as the diameter of the second forming paddles 130, thereby ensuring that the sludge passing through the first discharge space 140 and the sludge passing through the second discharge space 150 are squeezed to the same extent, so as to facilitate the dehydration of the sludge segments in the subsequent process.

[0073] like Figure 1 , Figure 3 and Figure 6 As 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 unloading parts 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 unloading area is located in the middle of the first drive roller 110 and the second drive roller 111. Therefore, by arranging the two rows of unloading parts 170 on opposite sides of the first drive roller 110 and the second drive roller 111, the unloading of the sludge strip segment will not be affected.

[0074] The belt filter press device 200 provided in some embodiments of the present application is as follows: Fig.13 As shown, the discharge port is provided with the above-mentioned uniform distribution device 100.

[0075] In this embodiment, the discharge port is located at the bottom of the belt filter press equipment 200, and a filter belt is also provided below the discharge port to realize automatic transportation of sludge strips.
