Description

Technical Field

[0001] The invention relates to the technical field of sludge dewatering, and in particular to sludge deep dewatering equipment with a deviation correction mechanism. Background Art

[0002] Intelligent deep sludge dewatering equipment is a continuously running sludge treatment equipment, which is mainly divided into plate and frame filter press, belt filter press, centrifugal dewatering machine and screw dewatering machine.

[0003] The Chinese patent with the announcement number CN215102793U discloses a sludge deep removal device, including

[0004] The machine comprises a frame; a sludge conveying device, the sludge conveying device being mounted on the frame; a sludge shaping device, the sludge shaping device being arranged on the frame; a sludge fixing device, the sludge fixing device being used to receive and fix the sludge conveyed by the sludge conveying device, the sludge fixing device being located in the frame; and a sludge squeezing device, the sludge squeezing device being mounted on the frame and being used to squeeze and dehydrate the sludge in the sludge fixing device.

[0005] The conveyor belt of the above patent is prone to deviation after running for a period of time. After the conveyor belt deviates, it needs to be stopped for adjustment. If the operator is not at his post and cannot correct it in time, it is easy to cause the conveyor belt to deviate seriously and tear. Summary of the Invention

[0006] The purpose of the present invention is to provide a sludge deep dewatering device with a deviation correction mechanism.

[0007] The innovation of the present invention is that a deviation-correcting mechanism is used to correct a deviated conveyor belt, so that the conveyor belt is in a stable working state, without the need for shutdown adjustment or manual operation, and the working efficiency is higher.

[0008] In order to achieve the above-mentioned object of the invention, the technical solution of the present invention is:

[0009] A sludge deep dewatering device with a deflection correction mechanism includes a frame, a sludge conveying device and a sludge fixing device mounted on the frame, the sludge conveying device including a first roller, a second roller, and a conveyor belt, the conveyor belt being wrapped around the first and second rollers, and a deflection correction mechanism mounted on the frame. Each deflection correction mechanism includes at least one tensioning assembly and two deflection correction sensors. The tensioning assembly includes two cylinders, two mounting blocks, and a tensioning roller. The two mounting blocks are mounted on the frame. The tensioning roller contacts the inner side of the conveyor belt, and the ends of the tensioning rollers are respectively rotatably mounted within the mounting blocks. The piston rods of the two cylinders are respectively connected to the corresponding mounting blocks. The two deflection correction sensors are mounted on the frame and located on either side of the lower side of the conveyor belt. Upon detecting deflection of the conveyor belt, the deflection correction sensors generate a signal that is transmitted to a controller and then fed back to the cylinders to adjust the tension on both sides of the conveyor belt, thereby correcting the deflection of the conveyor belt and maintaining a stable operating state. This eliminates the need for machine downtime adjustment or manual operation, thereby improving work efficiency.

[0010] Preferably, two tensioning assemblies are arranged in a vertical arrangement, with the tensioning rollers of the second tensioning assembly contacting the outer side of the conveyor belt. If only one tensioning assembly is provided, the piston rod may extend too far beyond the frame when tensioning the conveyor belt, making the entire frame too large and occupying a large space. With two tensioning assemblies, two cylinders are used to change the conveyor belt's transport direction, shortening the distance.

[0011] Preferably, the upper and lower sides of the conveyor belt are arranged horizontally, so as to facilitate the horizontal and stable transfer of sludge to various devices.

[0012] Preferably, the frame is provided with a slider arranged along the direction of movement of the cylinder piston rod, and a slide groove is provided below each mounting seat for sliding along the slider. The slider and slide groove serve to guide the movement of the first roller and the second roller, thereby preventing the first roller and the second roller from tilting during movement and improving the accuracy of adjustment of the first roller and the second roller.

[0013] Preferably, the sludge fixing device includes an upper mold, a filter plate and a pressure ring, the filter plate is fixed to the bottom of the upper mold by the pressure ring, the outer ring of the upper mold is provided with a joint ear, the outer ring of the pressure ring is provided with a joint shaft adapted to the joint ear, the pressure ring rotates on the joint ear through the joint shaft, the outer ring of the upper mold is provided with a positioning block arranged opposite to the joint ear, the positioning block is provided with a small hole, the outer ring of the pressure ring is provided with a positioning hole corresponding to the small hole, and a pin shaft is passed through the small hole and the positioning hole. The existing sludge fixing device has a large structure. When fixing the pressure ring, two operators are required to lift the pressure ring to the bottom of the upper mold, find the installation position of the bolts, and then the third operator installs the bolts one by one. The two operators take a long time to lift the pressure ring, which is time-consuming and labor-intensive. Joint ears and joint shafts are provided to enable one side of the pressure ring to rotate on the upper mold. After the positioning hole on the other side of the pressure ring is aligned with the small hole, the pin is inserted to preliminarily position the pressure ring, filter plate and lower mold, which is convenient for installing the bolts. After the bolts are installed, the pin can be removed, which saves the operators from lifting the pressure ring for a long time and is safer.

[0014] The beneficial effects of the present invention are:

[0015] 1. The deviation correction mechanism can correct the conveyor belt that has deviated, so that the conveyor belt is in a stable working state, without the need to stop the machine for adjustment or manual operation, with a high degree of automation and higher work efficiency.

[0016] 2. The use of joint ears and joint shafts enables one side of the pressing ring to rotate on the upper die; the use of positioning holes, small holes and pins can position the other side of the pressing ring, making it easier to install bolts without the need for manual lifting for a long time, thereby improving efficiency and safety.

[0030] like Figure 1 、 Figure 2 as well as Figure 3 As shown, a sludge deep dewatering device with a correction mechanism includes a frame 1, on which a sludge conveying device 2 and a sludge fixing device 7 are provided. The sludge conveying device 2 includes a first roller 21, a second roller 22, and a conveyor belt 23 wrapped around the first roller 21 and the second roller 22. The upper and lower sides of the conveyor belt 23 are both arranged horizontally. The frame 1 is provided with a correction mechanism, and the correction mechanism is located below the second roller 22. Each correction mechanism includes at least one tensioning assembly 3 and two correction sensors 4. The tensioning assembly 3 includes two cylinders 31, two mounting seats 32, and a tensioning roller 33. The tensioning roller 33 contacts the inner side of the conveyor belt 23 and is parallel to the second roller 22. The two mounting seats 32 are provided on the frame 1 and are respectively located at both ends of the tensioning roller 33. The ends of the tensioning roller 33 are respectively mounted in the corresponding mounting seats 32 via bearings. The piston rods of the two cylinders 31 are connected to corresponding mounting blocks 32. A chute 5 is defined beneath the mounting blocks 32. A slider 6 is provided on the frame 1 to mate with the chute 5. The chute 5 slides onto the slider 6. Two tension sensors are mounted on the frame 1, located on either side of the lower layer of the conveyor belt 23. Preferably, two sets of tensioning assemblies 3 are arranged vertically. The second set of tensioning assemblies 3 is located between the second roller 22 and the first set of tensioning assemblies 3, with the tensioning roller 33 of the second set of tensioning assemblies 3 contacting the outer side of the conveyor belt 23.

[0031] like Figures 4 to 8 As shown, the sludge fixing device 7 includes an upper mold 71, a filter plate 72 and a pressing ring 73. The filter plate 72 is fixed to the bottom of the upper mold 71 by the pressing ring 73. A joint ear 711 is provided on the outer ring of the upper mold 71, and a joint shaft 731 adapted to the joint ear 711 is provided on the outer ring of the pressing ring 73. The pressing ring 73 rotates on the joint ear 711 through the joint shaft 731. A positioning block 8 arranged opposite to the joint ear 711 is provided on the outer ring of the upper mold 71, and a small hole 81 is opened on the positioning block 8. A positioning hole 732 corresponding to the small hole 81 is provided on the outer ring of the pressing ring 73, and a pin is passed through the small hole 81 and the positioning hole 732.

[0032] In summary,

[0033] When the conveyor belt 23 deviates, the deviation correction sensor 4 on one side detects a signal and sends the signal to the control cabinet. The control cabinet feeds the signal back to the corresponding cylinder 31. The cylinder 31 is actuated to push the first roller 21 to move, adjust the tightness of the conveyor belt 23, and achieve the effect of correcting the position of the conveyor belt 23.

[0034] When installing the filter plate 72, first place the joint shaft 731 of the pressing ring 73 on the joint ear 711, then lift the other side of the pressing ring 73 so that the positioning hole 732 is aligned with the small hole 81, and insert the pin shaft, and then use bolts to fix the pressing ring 73, filter plate 72, and upper mold 71 together. After fixing, the pin shaft can be taken out. It is not only convenient to operate but also safer.
