Marine filter press sludge dewatering equipment requires manual opening and closing of components and sludge handling; the feeding, compression, and discharge processes are not streamlined and require significant manual intervention, resulting in high operating costs and low dewatering efficiency.

[0012] Compared with the prior art, this utility model provides a multi-stage filter press sludge dewatering device, which has the following beneficial effects:

[0013] 1. This multi-stage filter press sludge dewatering device, when sludge needs to be dewatered by filter press, pours the coagulated sludge onto the top of the inclined plate, and then the sludge slides on the inclined plate. At the same time, some of the water in the sludge is filtered through the filter holes into the water collection box, while the sludge accumulates under the obstruction of the baffle. Then, the motor drives the drive gear to rotate, and the drive gear drives the opening and closing mechanism to open, causing the lifting mechanism to rise. At the same time, the lifting mechanism drives the baffle to rise, and then the sludge flows under the baffle. Then, the motor is controlled to rotate the drive gear in the opposite direction, and the baffle descends to block the flow of the remaining sludge, while the opening and closing mechanism closes. The sludge enters the squeezing enclosure above the opening and closing mechanism. Then, the hydraulic cylinder is activated to press the filter plate down to press the sludge below, and excess water flows out from the outlet of the filter plate. Finally, the lifting mechanism is rotated again to open the opening and closing mechanism, causing the sludge cake to fall off. At the same time, the untreated sludge flows towards the squeezing enclosure. This solves the problem of traditional devices requiring manual opening and closing of parts and sludge handling, and realizes the automation of sludge feeding and discharging, reducing manual intervention and lowering operating costs.

[0014] 2. This multi-stage filter press sludge dewatering device, after pressing is completed, starts the motor to drive the drive gear to rotate. Because the drive gear meshes with the outer teeth of the gear ring, it drives the gear ring to rotate. The inner teeth of the gear ring mesh with the gear, causing the gear to rotate. The gear then meshes with the rack on one side of the slider, pushing the slider to slide in the groove at the bottom of the collection box. The slider drives the opening and closing block to achieve the opening and closing action. During filtration, the opening and closing block is closed to provide support for the filter plate. During discharge, the hydraulic cylinder drives the filter plate to rise, and the opening and closing block opens to allow the sludge cake to be discharged. In this way, the motor power is converted into an automated opening and closing action, without the need for manual intervention, completely eliminating the inefficiency and inconvenience of traditional manual operation.

[0015] 3. This multi-stage filter press sludge dewatering device, when the drive gear drives the opening and closing mechanism to open and close, the drive gear, in conjunction with gear two, rotates. At this time, the screw rises through the thread and passes through the friction seat, driving the baffle to rise. Sludge flows from the inclined plate. When the opening and closing mechanism closes, gear two reverses, causing the screw to descend, and the baffle re-adheres to the top of the inclined plate to block the sludge. Simultaneously, the sludge flows into the area above the closed opening and closing mechanism. This ensures an orderly connection of the dewatering process, precisely controls the timing of sludge flow, eliminates manual intervention, improves process accuracy, and increases dewatering efficiency. Parts not described in this device are the same as or can be implemented using existing technology. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] A multi-stage filter press sludge dewatering device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The system includes a collection box 1, an opening and closing mechanism 2 rotatably connected to the top of the inner wall of the collection box 1, a compression box 3 fixedly connected to the top of the collection box 1, a hydraulic cylinder 4 fixedly connected to the top of the compression box 3, and the telescopic end of the hydraulic cylinder 4 passing through the top of the compression box 3. A filter plate 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4. A squeezing fence is fixedly connected to the top of the squeezing fence, an inclined plate 6 is fixedly connected to the top of the squeezing fence, a bracket 9 is fixedly connected to one side of the inclined plate 6, and the bracket 9 is fixedly connected to the collection box 1. A lifting mechanism 8 is fixedly connected to the outer surface of the collection box 1, a baffle 7 is rotatably connected to the top of the lifting mechanism 8, a water collection box is fixedly connected to the bottom of the inclined plate 6, and a filter hole is opened on the top of the inclined plate 6. A drive gear 10 is rotatably connected to the top of the inner wall of the collection box 1, and a motor 11 is fixedly connected to the bottom of the inner wall of the collection box 1, and the output end of the motor 11 is fixedly connected to the drive gear 10.

[0025] When sludge needs to be dewatered by filter press, the coagulated sludge is poured onto the top of the inclined plate 6. The sludge then slides on the inclined plate 6, while some of the water in the sludge is filtered through the filter holes into the water collection box, and the sludge accumulates under the obstruction of the baffle 7.

[0026] Then, the motor 11 drives the drive gear 10 to rotate. The drive gear 10 drives the opening and closing mechanism 2 to open, which causes the lifting mechanism 8 to rise. At the same time, the lifting mechanism 8 drives the baffle 7 to rise, and then the sludge flows under the baffle 7.

[0027] Next, control the motor 11 to rotate in the opposite direction to drive the gear 10. This baffle 7 descends to block the flow of the remaining sludge, and the opening and closing mechanism 2 closes. The sludge enters the squeezing enclosure above the opening and closing mechanism 2. Then, the oil cylinder 4 is activated to press the filter plate 5 down to press the sludge below. Excess water flows out from the outlet of the filter plate 5.

[0028] Finally, the lifting mechanism 8 is rotated again to open the opening and closing mechanism 2, causing the mud cake to fall off. At the same time, the untreated sludge flows towards the squeezing fence. This solves the problem of traditional devices requiring manual opening and closing of parts and handling of sludge. It also automates sludge feeding and discharging, reduces manual intervention, and lowers operating costs.

[0029] To support sludge compression while simultaneously removing sludge cake, such as Figure 2 and Figure 3 As shown, the opening and closing mechanism 2 includes a gear ring 201, a gear 202, an opening and closing block 203, and a slider 204. The gear ring 201 is rotatably connected to the bottom of the collection box 1, the gear 202 is rotatably connected to the bottom of the collection box 1, a groove is provided at the bottom of the collection box 1, the slider 204 is slidably connected to the inner wall of the groove, the opening and closing block 203 is fixedly connected to the outer wall of the slider 204, and the gear ring 201 has external teeth on its outer edge and internal teeth on its inner edge. The internal teeth mesh with the gear 202, and the external teeth mesh with the drive gear 10. A rack is provided on one side of the slider 204, and the slider 204 meshes with the gear 202.

[0030] After extrusion is completed, the motor 11 is started to run, driving the drive gear 10 to rotate. Because the drive gear 10 meshes with the external teeth of the gear ring 201, it drives the gear ring 201 to rotate.

[0031] The inner teeth of the gear ring 201 mesh with the gear 202, causing the gear 202 to rotate. The gear 202 then meshes with the rack on one side of the slider 204, pushing the slider 204 to slide in the groove at the bottom of the collection box 1.

[0032] The slider 204 drives the opening and closing block 203 to achieve the opening and closing action. During the filter pressing, the opening and closing block 203 closes to provide support for the filter plate 5. During the discharge, the oil cylinder 4 drives the filter plate 5 to rise, and the opening and closing block 203 opens to allow the mud cake to be discharged. In this way, the power of the motor 11 is converted into an automated opening and closing action without manual intervention, completely getting rid of the inefficiency and inconvenience of traditional manual operation.

[0033] To allow the sludge to flow into the squeezing enclosure, as shown in the figure, the lifting mechanism 8 includes a second gear 801, a friction seat 802, and a screw 803. The second gear 801 is rotatably connected to the bottom of the collection box 1, the screw 803 is threadedly connected to the inner wall of the second gear 801, the friction seat 802 is fixedly connected to the top of the collection box 1, and the screw 803 passes through the bottom of the friction seat 802. The baffle 7 is rotatably connected to the top of the screw 803.

[0034] When the drive gear 10 drives the opening and closing mechanism 2 to open and close, the drive gear 10 is linked to the gear 801 to rotate. At this time, the screw 803 rises through the thread and passes through the friction seat 802 to drive the baffle 7 to rise. At this time, the sludge flows from the inclined plate 6.

[0035] When the opening and closing mechanism 2 is closed, gear 2 801 reverses, causing screw 803 to descend. Baffle 7 re-fits to the top of inclined plate 6 to block sludge. At the same time, sludge flows into the top of the already closed opening and closing mechanism 2. This ensures that the dewatering process is connected in an orderly manner, accurately controls the timing of sludge flow, eliminates manual intervention, improves process accuracy, and increases dewatering efficiency.

[0036] Work process: When sludge needs to be dewatered by filter press, the coagulated sludge is poured into the top of the inclined plate 6. The sludge then slides on the inclined plate 6, while some of the water in the sludge is filtered through the filter holes into the water collection box, and the sludge accumulates under the obstruction of the baffle 7.

[0037] Then, the motor 11 drives the drive gear 10 to rotate. The drive gear 10 drives the opening and closing mechanism 2 to open, which causes the lifting mechanism 8 to rise. At the same time, the lifting mechanism 8 drives the baffle 7 to rise, and then the sludge flows under the baffle 7.

[0038] Next, control the motor 11 to rotate in the opposite direction to drive the gear 10. This baffle 7 descends to block the flow of the remaining sludge, and the opening and closing mechanism 2 closes. The sludge enters the squeezing enclosure above the opening and closing mechanism 2. Then, the oil cylinder 4 is activated to press the filter plate 5 down to press the sludge below. Excess water flows out from the outlet of the filter plate 5.

[0039] Finally, rotate the lifting mechanism 8 again to open the opening and closing mechanism 2, causing the mud cake to fall off, while the untreated sludge flows towards the squeezing fence.

[0040] After extrusion is completed, the motor 11 is started to run, driving the drive gear 10 to rotate. Because the drive gear 10 meshes with the external teeth of the gear ring 201, it drives the gear ring 201 to rotate.

[0041] The inner teeth of the gear ring 201 mesh with the gear 202, causing the gear 202 to rotate. The gear 202 then meshes with the rack on one side of the slider 204, pushing the slider 204 to slide in the groove at the bottom of the collection box 1.

[0042] The slider 204 drives the opening and closing block 203 to achieve the opening and closing action. During filter pressing, the opening and closing block 203 is closed to provide support for the filter plate 5. During discharge, the hydraulic cylinder 4 drives the filter plate 5 to rise, and the opening and closing block 203 opens to allow the mud cake to be discharged.

[0043] When the drive gear 10 drives the opening and closing mechanism 2 to open and close, the drive gear 10 is linked to the gear 801 to rotate. At this time, the screw 803 rises through the thread and passes through the friction seat 802 to drive the baffle 7 to rise. At this time, the sludge flows from the inclined plate 6.

[0044] When the opening / closing mechanism 2 is closed, gear 801 reverses, causing screw 803 to descend. Baffle 7 then re-adhere to the top of inclined plate 6 to block sludge, while the sludge flows into the area above the already closed opening / closing mechanism 2. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
