Therefore, sugarcane is widely planted in our country, and the number of sugar factories is increasing continuously, which not only increases the income of farmers but also promotes the development of the industry. After the clarification treatment of sugarcane juice, solid-liquid separation is required. Due to the constraints of sugar production process requirements, the water content of the filter mud obtained after solid-liquid separation of sugarcane juice is as high as 70%.

Detailed implementation manners

[0025] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0026] The following describes in detail the specific implementation of the present invention in combination with specific embodiments.

[0027] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, it is a structural diagram of a sugar mill filter mud dewatering device provided by an embodiment of the present invention, including a fixed cylinder 1. A feed cylinder 2 is fixedly installed at the bottom end of the fixed cylinder 1. Brackets 21 are respectively arranged on both sides of the feed cylinder 2. Dewatering cylinders 3 are respectively fixedly installed on both sides of the fixed cylinder 1. The dewatering cylinders 3 are arranged in an inclined shape. The dewatering cylinders 3 and the feed cylinder 2 are respectively communicated with the fixed cylinder 1. One end of the dewatering cylinder 3 far away from the fixed cylinder 1 is arranged in an open shape. A column 4 is rotatably installed in the inner cavity of the fixed cylinder 1. A fixing plate 41 is fixedly installed in the inner cavity of the fixed cylinder 1. The fixing plate 41 is rotatably connected to the bottom end of the column 4. A motor 42 is fixedly installed on the surface of the fixed cylinder 1. The output shaft of the motor 42 is connected to the column 4. A feeding mechanism 5 is arranged in the inner cavity of the feed cylinder 2. The feeding mechanism 5 includes a suction component 51 and a transmission component 52. The suction component 51 is located in the inner cavity of the feed cylinder 2. The transmission component 52 is connected to the suction component 51. When the column 4 rotates, the transmission component 52 sucks the filter mud into the feed cylinder 2 and intermittently transports a fixed amount of filter mud into the dewatering cylinder 3 by cooperating with the suction component 51. A plurality of extrusion rollers 6 are arranged along the length direction in the inner cavity of the dewatering cylinder 3. A control mechanism 7 that cooperates with the extrusion rollers 6 is arranged in the inner cavity of the dewatering cylinder 3. The control mechanism 7 includes a positioning component 71, a rotating component 72, a material guiding component 73 and a diversion component 74. The positioning component 71 is located in the inner cavity of the dewatering cylinder 3 and is connected to the extrusion rollers 6. The positioning component 71 is used to control the plurality of extrusion rollers 6 to be annularly distributed around the axis of the dewatering cylinder 3. The rotating component 72 is connected to the positioning component 71. When the column 4 rotates, the rotating component 72 controls the plurality of extrusion rollers 6 to rotate synchronously in the inner cavity of the dewatering cylinder 3 by cooperating with the positioning component 71. The material guiding component 73 is connected to the positioning component 71. When the extrusion rollers 6 rotate, the material guiding component 73 controls the filter mud to move intermittently from high to low in the dewatering cylinder 3 by cooperating with the positioning component 71. The diversion component 74 is located at the bottom wall of the dewatering cylinder 3. The diversion component 74 is used to collect the discharged water.

[0028] In use, the feed cylinder 2 is inserted into the filter mud pond. The bracket 21 can stably support the feed cylinder 2. Start the motor 42, and the motor 42 drives the column 4 to rotate inside the fixed cylinder 1. When the column 4 rotates, the transmission assembly 52 and the suction assembly 51 cooperate with each other to continuously suck the filter mud in the filter mud pond into the inner cavity of the feed cylinder 2. The suction assembly 51 and the transmission assembly 52 cooperate with each other to further push the filter mud in the inner cavity of the feed cylinder 2 to move upward, and intermittently deliver an appropriate amount of filter mud into the dehydration cylinder 3. The filter mud delivered into the dehydration cylinder 3 moves from a high place to a low place. The rotation assembly 72 and the positioning assembly 71 cooperate with each other to control multiple groups of pressing rollers 6 to rotate in sequence along the length direction of the dehydration cylinder 3 inside the dehydration cylinder 3. When the pressing rollers 6 rotate, they can efficiently roll and dehydrate the filter mud in the dehydration cylinder 3. After the previous group of pressing rollers 6 finish rotating and rolling, the material guiding assembly 73 and the inclined dehydration cylinder 3 cooperate with each other to control the pressed filter mud to move obliquely downward by a certain distance inside the inner cavity of the dehydration cylinder 3. After the filter mud moves a certain distance, the next group of pressing rollers 6 can roll and dehydrate the filter mud again. Repeating this process multiple times, multiple groups of pressing rollers 6 can perform multiple rolling and dehydration treatments on the filter mud inside the dehydration cylinder 3. When the filter mud after multiple rollings moves to the bottom opening of the dehydration cylinder 3, the dehydrated filter mud can automatically discharge from the bottom of the dehydration cylinder 3. When the rotating pressing rollers 6 roll and dehydrate the filter mud, the diversion assembly 74 can quickly separate and collect the discharged water.

[0029] As Figure 1 , Figure 2 , Figure 3 shown, as a preferred embodiment of the present invention, the suction assembly 51 includes a vertical rod 512 rotatably installed in the inner cavity of the feed cylinder 2. A spiral auger 513 is arranged on the surface of the vertical rod 512, and a feed port 511 is opened at the bottom end of the side wall of the feed cylinder 2.

[0030] The filter mud in the filter mud pond flows through the feed port 511 into the inner cavity of the feed cylinder 2. When the column 4 rotates, the transmission assembly 52 controls the vertical rod 512 to intermittently rotate a certain angle inside the inner cavity of the feed cylinder 2. The vertical rod 512 drives the spiral auger 513 to rotate synchronously inside the inner cavity of the feed cylinder 2. The spiral auger 513 can push the filter mud in the feed cylinder 2 to move from bottom to top. The spiral auger 513 rotates intermittently, and can intermittently deliver a fixed amount of filter mud into the inner cavity of the dehydration cylinder 3.

[0031] As Figure 2 , Figure 3 , Figure 6As shown, as a preferred embodiment of the present invention, the transmission assembly 52 includes a first driven bevel gear disk 521 fixedly installed at the top end of the vertical rod 512. A rotating column 522 is rotatably installed on the inner side wall of the fixed cylinder 1. A first driving bevel gear disk 523 meshingly connected with the first driven bevel gear disk 521 is fixedly installed on the surface of the rotating column 522. A transmission disk 524 is fixedly installed on the surface of the column 4. An arc-shaped rack 525 is arranged on the surface of the transmission disk 524. The rack 525 meshes and cooperates with the first driving bevel gear disk 523.

[0032] When the column 4 rotates, it drives the transmission disk 524 to rotate synchronously. The transmission disk 524 drives the rack 525 to rotate synchronously. When the rack 525 rotates to contact the first driving bevel gear disk 523, the rack 525 and the first driving bevel gear disk 523 are in meshing transmission, which can drive the first driving bevel gear disk 523 to rotate in the inner cavity of the fixed cylinder 1. The first driving bevel gear disk 523 and the first driven bevel gear disk 521 are in meshing transmission, which can drive the vertical rod 512 to rotate in the inner cavity of the feeding cylinder 2. The vertical rod 512 drives the spiral auger 513 to rotate, thereby pushing the filter mud to move upward in the inner cavity of the feeding cylinder 2. The rack 525 continues to rotate. When the rack 525 separates from the first driving bevel gear disk 523, the first driving bevel gear disk 523 stops rotating. At this time, the vertical rod 512 stops rotating synchronously in the inner cavity of the feeding cylinder 2. At this time, the spiral auger 513 stops pushing the filter mud to move upward in the inner cavity of the feeding cylinder 2.

[0033] As Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, as a preferred embodiment of the present invention, the positioning assembly 71 includes fixed seats 711 respectively fixedly installed at both ends of the inner cavity of the dehydration cylinder 3. A central shaft column 712 is rotatably installed by the two groups of fixed seats 711 together. A plurality of groups of side plates 713 distributed in pairs along the length direction are fixedly installed on the surface of the central shaft column 712. A bearing rod 714 is rotatably installed between the two relatively distributed side plates 713. The extrusion roller 6 is fixedly installed on the surface of the bearing rod 714.

[0034] The two groups of fixed seats 711 support the central shaft column 712 in the inner cavity of the dehydration cylinder 3. The central shaft column 712 and the side plates 713 cooperate with each other to support and position a plurality of groups of bearing rods 714 and the extrusion roller 6 in the inner cavity of the dehydration cylinder 3. When the column 4 rotates, the rotation assembly 72 controls the central shaft column 712 to rotate synchronously in the inner cavity of the dehydration cylinder 3. The central shaft column 712 drives a plurality of groups of extrusion rollers 6 to rotate in sequence along the length of the dehydration cylinder 3 in the inner cavity of the dehydration cylinder 3. When the extrusion roller 6 rotates, it can perform efficient rolling dehydration treatment on the filter mud in the dehydration cylinder 3.

[0035] As Figure 2 、 Figure 4 、Figure 6 As shown in the figure, as a preferred embodiment of the present invention, one end of the central shaft column 712 of the rotating assembly 72 extends towards the column 4 and is fixedly installed with a second driven bevel gear disc 721 inside the fixed cylinder 1. The surface of the column 4 is fixedly installed with a second driving bevel gear disc 722, and the second driven bevel gear disc 721 is meshed and connected with the second driving bevel gear disc 722.

[0036] When the column 4 rotates, it drives the second driving bevel gear disc 722 to rotate synchronously. The second driving bevel gear disc 722 meshes and drives with the second driven bevel gear disc 721, which can drive the central shaft column 712 to continuously rotate inside the inner cavity of the dewatering cylinder 3.

[0037] As Figure 2 、 Figure 4 、 Figure 5 As shown in the figure, as a preferred embodiment of the present invention, the material guiding assembly 73 includes an arc-shaped baffle 731 fixedly installed on the surface of the side plate 713 at the lowest position of the extrusion roller 6. Two sets of relatively distributed side plates 713 are jointly fixedly installed with a cross bar 732. A plurality of connecting rods 733 are fixedly installed on the surface of the cross bar 732. One ends of the plurality of connecting rods 733 away from the cross bar 732 are jointly fixedly installed with a scraping plate 734 located outside the extrusion roller 6.

[0038] When the filter mud moves from a high place to a low place inside the inner cavity of the dewatering cylinder 3, the central shaft column 712 drives the extrusion roller 6, the baffle 731, and the scraping plate 737 to rotate synchronously inside the inner cavity of the dewatering cylinder 3. When the baffle 731 rotates to the lower part of the central shaft column 712, the baffle 731 fits with the inner bottom wall of the dewatering cylinder 3. The baffle 731 can block the moving filter mud. After the filter mud is blocked, the extrusion roller 6 can perform efficient rolling and dewatering treatment on the filter mud. After single-time rolling and dewatering, the scraping plate 737 can shovel off the rolled filter mud attached to the inner bottom wall of the dewatering cylinder 3. After the baffle 731 rotates to the upper part of the central shaft column 712, the shoveled filter mud moves obliquely downward by a certain distance again inside the inner cavity of the dewatering cylinder 3. The next baffle 731 obliquely below can block the filter mud again, and the next extrusion roller 6 can perform rolling and dewatering on the filter mud again. In this way, through repeated cycles, the filter mud can be subjected to multiple rolling and dewatering operations inside the inner cavity of the dewatering cylinder 3.

[0039] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 As shown in the figure, as a preferred embodiment of the present invention, the diversion assembly 74 includes a diversion cavity 741 provided on the bottom wall of the dewatering cylinder 3. The bottom wall of the dewatering cylinder 3 is provided with uniformly distributed water seepage holes 742 that communicate with the diversion cavity 741. A control valve 743 is provided at the bottom end of the diversion cavity 741.

[0040] When the squeezing roller 6 rolls and dewater the filter mud in the inner cavity of the dewatering cylinder 3, the water separated from the filter mud flows through the water seepage holes 742 into the diversion cavity 741, and the accumulated water in the diversion cavity 741 can be conveniently discharged through the control valve 743.

[0041] As Figure 4 , Figure 5 , Figure 7 shown, as a preferred embodiment of the present invention, a guiding gear disk 81 is fixedly installed at one end of the bearing rod 714, an arc-shaped guiding rack 82 is fixedly installed in the inner cavity of the dewatering cylinder 3 through a support rod, and the guiding rack 82 is engaged with the guiding gear disk 81.

[0042] When the squeezing roller 6 rotates in the inner cavity of the dewatering cylinder 3, it drives the guiding gear disk 81 to rotate synchronously. When the squeezing roller 6 rotates to the lower part of the central shaft column 712, the guiding gear disk 81 at the end of the squeezing roller 6 rolls along the surface of the guiding rack 82. The guiding gear disk 81 controls the squeezing roller 6 to rotate around the central shaft column 712 while rotating itself, which can further improve the rolling and dewatering effect of the squeezing roller 6 on the filter mud.

[0043] The working principle of the present invention is as follows: during use, the feeding cylinder 2 is inserted into the filter mud pond, and the bracket 21 can stably support the feeding cylinder 2. The filter mud in the filter mud pond flows through the feeding port 511 into the inner cavity of the feeding cylinder 2. Start the motor 42, and the motor 42 drives the column 4 to rotate in the inner cavity of the fixed cylinder 1. When the column 4 rotates, it drives the transmission disk 524 to rotate synchronously, and the transmission disk 524 drives the inclined rack 525 to rotate synchronously. When the inclined rack 525 rotates to contact the first driving bevel gear disk 523, the inclined rack 525 and the first driving bevel gear disk 523 are engaged and driven, which can drive the first driving bevel gear disk 523 to rotate in the inner cavity of the fixed cylinder 1. The first driving bevel gear disk 523 and the first driven bevel gear disk 521 are engaged and driven, which can drive the vertical rod 512 to rotate in the inner cavity of the feeding cylinder 2, and the vertical rod 512 drives the spiral auger 513 to rotate, thereby pushing the filter mud to move upward in the inner cavity of the feeding cylinder 2. The inclined rack 525 continues to rotate. When the inclined rack 525 is separated from the first driving bevel gear disk 523, the first driving bevel gear disk 523 stops rotating. At this time, the vertical rod 512 stops rotating synchronously in the inner cavity of the feeding cylinder 2, and at this time, the spiral auger 513 stops pushing the filter mud to move upward in the inner cavity of the feeding cylinder 2. The spiral auger 513 rotates intermittently, and can intermittently convey a fixed amount of filter mud into the inner cavity of the dewatering cylinder 3.

[0044] When the vertical column 4 rotates, it drives the second active helical gear disc 722 to rotate synchronously. The second active helical gear disc 722 meshes with the second driven helical gear disc 721 for transmission, which can drive the central shaft column 712 to continuously rotate inside the dehydration cylinder 3. When the filter mud moves from a high place to a low place inside the dehydration cylinder 3, the central shaft column 712 drives the extrusion roller 6, the baffle 731 and the scraper 737 to rotate synchronously inside the dehydration cylinder 3. When the baffle 731 rotates to the lower part of the central shaft column 712, the baffle 731 fits with the inner bottom wall of the dehydration cylinder 3, and the baffle 731 can block the moving filter mud. After the filter mud is blocked, the extrusion roller 6 can perform efficient rolling dehydration treatment on the filter mud. After single-time rolling dehydration, the scraper 737 can shovel off the rolled filter mud attached to the inner bottom wall of the dehydration cylinder 3. After the baffle 731 rotates to the upper part of the central shaft column 712, the shoveled filter mud moves obliquely downward again by a certain distance inside the dehydration cylinder 3, and the next group of baffles 731 obliquely below can block the filter mud again, and the next group of extrusion rollers 6 can perform rolling dehydration on the filter mud again. In this way, the filter mud can be subjected to multiple rolling dehydrations inside the dehydration cylinder 3. When the filter mud after multiple rollings moves to the bottom opening of the dehydration cylinder 3, the dehydrated filter mud can automatically be discharged from the bottom of the dehydration cylinder 3. When the rotating extrusion roller 6 performs rolling dehydration on the filter mud, the water separated from the filter mud flows through the water seepage holes 742 into the diversion cavity 741, and the accumulated water in the diversion cavity 741 can be conveniently discharged by controlling the valve 743.

[0045] The above has described in detail the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
