[0036] The following is in conjunction with the appendix Figure 1 To be continued Figure 8 This application will be described in further detail.

[0037] Reference Figure 1 and Figure 2 This application discloses a connecting conveying device (hereinafter referred to as "connecting conveying device") for sludge between plate and frame press sludge and dried sludge, comprising a lifting scraper conveyor 5 and a powder screw conveyor 6. The connecting conveying device is used to connect the sludge movement between the plate and frame press 1 and the disc dryer 2. One end of the lifting scraper conveyor 5 receives the sludge flowing out of the plate and frame press 1, and the other end extends upward at an angle above the powder screw conveyor 6. The powder screw conveyor 6 receives the sludge fed in by the lifting scraper conveyor 5 and divides the sludge into two parts, which are respectively sent to the corresponding disc dryers 2. The sludge is dried in the disc dryers 2 until the dried sludge is discharged. In order to increase the sludge treatment efficiency, this application can set up two sets of disc dryers 2 to process the sludge. This application sets up the powder screw conveyor 6 on the two disc dryers 2, and sets up the lifting scraper 5 to lift the sludge to a suitable height and divert the sludge in the lifting scraper 5, so as to process more sludge at the same time.

[0038] Reference Figure 2 and Figure 3Furthermore, the connecting transport device also includes a sludge crusher 4, which is located above the starting end of the lifting scraper conveyor 5. The sludge pressed in the plate and frame sludge press 1 enters the sludge crusher 4 to crush the agglomerated sludge. A discharge pipe 43 is provided at the bottom of the sludge crusher 4, corresponding to the interior of the lifting scraper conveyor 5. The crushed sludge enters the lifting scraper conveyor 5 for lifting. Specifically, the sludge crusher 4 includes a casing 41, a feed pipe 42, and crushing components 44. The casing 41 is a hollow cylinder; the upper surface of the casing 41 is connected to the feed pipe 42, and the lower surface of the casing 41 is connected to the discharge pipe 43. The sludge enters the casing 41 through the feed pipe 42 and is crushed by the crushing components 44 located within the casing 41. The crushed sludge falls into the lifting scraper conveyor 5 through the discharge pipe 43. Multiple crushing components 44 can be horizontally arranged to increase crushing efficiency and the degree of crushing. The crushing assembly 44 includes a plurality of crushing blades 441, a drive rod 442, and a first drive element 443. The crushing blades 441 are arranged in a circumferential array on the outer wall of the drive rod 442, and extend outward perpendicularly to the drive rod 442. One end of the drive rod 442 extends through the housing 41 to the outside and connects to the output end of the first drive element 443; the drive rod 442 rotates relative to the housing 41. The first drive element 443 is a motor, and its outer casing is connected to the housing 41.

[0039] Reference Figure 2 and Figure 3 Generally, the sludge discharged from the plate and frame sludge press 1 is first received and transported by a belt conveyor. Due to the structural limitations of the belt conveyor, the sludge easily adheres to the surface of the belt conveyor, and the sludge falls into the next process only under the action of gravity. This is not only inefficient, but also easily causes the sludge to remain for a long time, leading to sludge putrefaction. Therefore, the connecting transport device also includes a horizontal scraper conveyor 3. The horizontal scraper conveyor 3 is set between the plate and frame sludge press 1 and the sludge crusher 4, and the end of the horizontal scraper conveyor 3 away from the plate and frame sludge press 1 is connected to the feed pipe 42. By adding the horizontal scraper conveyor 3 to transport the sludge horizontally, the laying of the belt conveyor can be shortened, thereby reducing sludge retention. Furthermore, if site conditions and costs permit, the horizontal scraper conveyor 3 can be directly used to replace the belt conveyor, thereby avoiding the situation of sludge adhering to the belt.

[0040] Reference Figure 2 and Figure 4Furthermore, the lifting scraper conveyor 5 includes a housing 51, several scrapers 52, a drive chain 53, drive gears 54, a second drive component 55, and a steering support roller 56. The housing 51 includes a receiving section 511, a lifting section 512, and a discharging section 513. The receiving section 511 is parallel to the ground and supported by several support legs. One end of the lifting section 512 is connected to the receiving section 511, and the other end extends obliquely upward to the top of the disc dryer 2. The discharging section 513 is connected to the lifting section 512 and extends horizontally upward to the top of the powder screw conveyor 6. The discharging section 513 is provided with a mud inlet pipe 515, which connects to the powder screw conveyor 6. Two sets of drive chains 53 are provided, and the two sets of drive chains 53 are respectively located near the two side walls of the housing 51. Each set of drive chains 53 is provided with two drive gears 54. The drive chain 53 is connected end to end to form a closed ring structure. Drive gears 54 are located at both ends of the drive chain 53, with the drive chain 53 fitted over the drive gears 54, and the drive chain 53 meshes with the drive gears 54. Drive gears 54 in corresponding positions of different groups are connected by coaxial linkage rods, allowing adjacent drive gears 54 to rotate simultaneously. The drive chain 53 is laid along the length of the housing 51 and bends at the connection points of the receiving section 511, lifting section 512, and unloading section 513, thus forming a shape consistent with the orientation of the housing 51. A horizontally protruding tab 514 on the inner wall of the housing 51 supports the upper drive chain 53, and the tab 514 is laid along the length of the housing 51. Several steering support rollers 56 are distributed at the connection points of the receiving section 511, lifting section 512, and unloading section 513 to support the drive chain 53 for steering. The second driving component 55 is a motor. Two second driving components 55 are provided, corresponding to the driving gears 54. The housing of the second driving component 55 is connected to the outer wall of the housing 51. The output end of the second driving component 55 passes through the side wall of the housing 51 and is coaxially connected to the corresponding driving gear 54. The horizontal scraper conveyor 3 differs from the lifting scraper conveyor 5 only in direction; its principle and structure are similar, and will not be described further here.

[0041] Reference Figure 2 and Figure 4Furthermore, the powder screw conveyor 6 includes a casing 61, a bidirectional screw rod 62, a third drive component 63, and two sludge discharge pipes 64. The casing 61 is a long cylindrical shell 51, and the bidirectional screw rod 62 is coaxially connected inside the casing 61, with the screw rod rotatably connected inside the casing 61. The third drive component 63 is a motor, with its outer casing connected to one end of the casing 61, and its output end inserted into the casing 61 and coaxially connected to the bidirectional screw rod 62. The sludge inlet pipe 515 is connected to the upper surface of the casing 61 at its middle position, and the sludge discharge pipes 64 are vertically connected to both ends of the casing 61, with the sludge discharge pipes 64 vertically downwards connected to the corresponding disc dryers 2. When sludge enters the casing 61 through the sludge inlet pipe 515, the bidirectional screw rod 62 rotates, causing the sludge to flow in two opposing directions and enter the corresponding disc dryers 2 for drying.

[0042] Because the top of the lifting scraper conveyor 5 is at a considerable height, and the sludge itself is quite viscous, at this height, the sticky sludge adheres to the scraper 52 and does not easily fall off, so it will return empty. This is a waste of stroke, and in hot weather, the sludge adhering to the scraper 52 is prone to putrefaction and the generation of harmful substances. Therefore, this example also includes a cleaning mechanism 7 located at the end of the lifting scraper conveyor 5 for cleaning the sludge adhering to the scraper 52. The cleaning mechanism 7 includes a frame 71, a cleaning scraper 72, a control component 8, and a reset component 9.

[0043] Reference Figures 4 to 6Specifically, the frame 71 is connected to the end of the housing 51 away from the ground. The frame 71 includes a connecting section 711 and a support section 712. One end of the connecting section 711 is connected to the end of the housing 51, and the other end extends vertically upward to connect to one end of the support section 712. The connecting section 711 and the support section 712 are connected at an angle of 90 degrees. The support section 712 extends along the movement trajectory of the scraper 52 and is horizontally located above the housing 51. A support plate 713 extends vertically downward from the end of the support section 712. The control assembly 8 includes a slide rod 81, a transmission column 82, a sleeve 83, and a fourth drive component 84. One end of the slide rod 81 vertically passes through the middle of the support plate 713, and the end of the slide rod 81 passing through the support plate 713 is connected to the end of the cleaning scraper 72. The slide rod 81 rotates relative to the support rod. The cleaning scraper 72 is vertically connected to the slide rod 81 and can rotate with the slide rod 81 into the movement path of the scraper 52. The other end of the slide rod 81 is coaxially connected to the transmission column 82. The outer wall of the transmission column 82 has circumferentially oriented teeth 821, which are arranged along the length of the transmission column 82. The fourth driving component 84 is a motor. The housing 51 of the fourth driving component 84 is connected to the outside of the connecting section 711. The output shaft 841 of the fourth driving component 84 passes through the outer wall of the connecting section 711 to below the support section 712. The output shaft 841 of the fourth driving component 84 rotates relative to the connecting section 711. The output shaft 841 is parallel to the transmission column 82 and is on the same plane as the motor. The output shaft 841 of the fourth driving component 84 is coaxially connected to a control gear 842, which meshes with the transmission column 82 through the teeth 821. While the control gear 842 meshes with the transmission column 82, the transmission column 82 can move radially relative to the control gear 842. A connecting rod 85 is coaxially mounted on the end of the transmission column 82 away from the slide rod 81. One end of the sleeve 83 is connected to the inner wall of the connecting section 711, and the other end extends parallel to the length of the support section 712. The connecting rod 85 coaxially passes into the sleeve 83. The reset assembly 9 includes a transition block 91 and an elastic element 93. The end of the connecting rod 85 that passes into the sleeve 83 is rotatably connected to the transition block 91. The transition block 91 is coaxially slidably connected to the sleeve 83. Several limiting blocks 92 are arranged in a circumferential array on the outer wall of the transition block 91. A limiting groove 831 is formed along the length of the inner wall of the sleeve 83, and the limiting blocks 92 are slidably connected in the limiting groove 831. The elastic element 93 is a tension spring, which makes the transmission column 82 always tend to move closer to the position of the sleeve 83. The elastic element 93 is disposed in the sleeve 83. One end of the elastic element 93 is connected to the end of the transition block 91 away from the connecting rod 85, and the other end is connected to the inner wall of the end of the sleeve 83.

[0044] Reference Figure 7Furthermore, a first magnetic block 851 is circumferentially arranged at one end of the connecting rod 85 connected to the transmission column 82, and a second magnetic block 832 is arranged at the end of the sleeve near the transmission column 82 to attract the first magnetic block 851. When the reset assembly 9 resets the transmission column 82, the first magnetic block 851 and the second magnetic block 832 attract each other, reducing vibration caused by the elastic element 93. This makes the structure more stable in operation.

[0045] Reference Figure 5 and Figure 8 Furthermore, the cleaning mechanism 7 also includes an additional cleaning strip 73 and an additional rod 74. One end of the additional cleaning strip 73 is vertically connected to one end of the additional rod 74, and the end of the additional rod 74 away from the cleaning strip is provided with an insertion rod 741. The surface of the cleaning scraper 72 has an insertion hole 721 extending coaxially into the slide rod 81, and the insertion rod 741 can be inserted into the insertion hole 721. The surface of the cleaning scraper 72 has a fixing hole 722 perpendicular to the length of the insertion hole 721, and the fixing hole 722 communicates with the insertion hole 721. The fixing hole 722 is threadedly connected to a fixing bolt 723. The surface of the insertion rod 741 has a recessed hole 742 corresponding to the position of the fixing hole 722, and the fixing bolt 723 can pass through the fixing hole 722 into the recessed hole 742. This allows the cleaning assembly to be attached to clean multiple scrapers 52 simultaneously. Multiple sets of additional cleaning strips 73 and additional rods 74 can be provided; the principle of addition is the same, so it will not be described in detail again.

[0046] The implementation principle of a connecting conveying device for plate and frame press mud and dried mud in this application embodiment is as follows:

[0047] The sludge from the initial pressing by the plate and frame sludge press 1 is received by a horizontal scraper conveyor 3 and fed into a sludge crusher 4 to break up the agglomerated sludge. The crushed sludge is received at one end of an elevator scraper conveyor 5, while the other end extends upwards above a powder screw conveyor 6. The powder screw conveyor 6 receives the sludge fed in by the elevator scraper conveyor 5 and divides it into two portions, which are then sent to corresponding disc dryers 2 for drying until the dried sludge is discharged. This increases the sludge treatment efficiency.

[0048] On the other hand, refer to Figure 5 and Figure 6A cleaning mechanism 7 is provided at the highest point of the lifting scraper machine 5. Initially, the elastic element 93 is in a contracted state, the first magnetic block 851 and the second magnetic block 832 attract each other, the transmission column 82 and the sleeve 83 are in a close position, and the drive gear 54 drives the cleaning scraper 72 and the auxiliary cleaning strip 73 to rotate around the slide rod 81 through the teeth 821. At the same time, the scraper 52 moves. When the cleaning scraper 72 and the auxiliary cleaning strip 73 rotate into the moving path of the scraper 52, due to the interference of the scraper 52, the cleaning scraper 72 and the auxiliary cleaning strip 73 move together. At this time, the cleaning scraper 72 and the auxiliary cleaning strip 73 continue to rotate to clean the surface of the scraper 52 until the cleaning scraper 72 and the auxiliary cleaning strip 73 rotate out of the moving path of the scraper 52. The cleaning scraper 72 and the auxiliary cleaning strip 73 are reset under the action of the elastic element 93 to prepare for the next cleaning of the scraper 52.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
