DETAILED DESCRIPTION

[0017] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the utility model.

[0018] Please refer to Figures 1-3 A sludge dewatering device for sewage treatment, comprising a support assembly, a conveying assembly arranged on the support assembly and conveying sewage containing a large amount of sludge, and a sludge dewatering mechanism arranged on the support assembly and located at the output end of the conveying assembly, the sludge dewatering mechanism comprising a dewatering roller 3 arranged on the support assembly and located at the output end of the conveying assembly, two drive rollers 4 arranged symmetrically about the axis of the dewatering roller 3, two control rollers 7 arranged in parallel below the two drive rollers 4 and above the support assembly, a filter cloth belt 5 sleeved on the outer sides of the two drive rollers 4 and the two control rollers 7, and a control assembly arranged on the support assembly and controlling the two control rollers 7 to move up and down on the support assembly, the output end of the conveying assembly is located above one of the drive rollers 4 and the dewatering roller 3, and the upper surface of the filter cloth belt 5 located above the two drive rollers 4 is tightly attached to the bottom side of the dewatering roller 3.

[0019] As Figures 1-3As shown, the sludge is transported by the conveying assembly to the position between the dewatering roller 3 and the filter cloth belt 5, and the filter cloth belt 5 is sleeved on the two driving rollers 4 and the two control rollers 7, and the driving roller 4 is driven by the motor to drive the filter cloth belt 5 to move. When the sludge moves to the position between the dewatering roller 3 and the filter cloth belt 5, the sludge is dewatered by the pressing action between the dewatering roller 3 and the filter cloth belt 5. The control assembly drives the two control rollers 7 to move up and down, which facilitates the adjustment of the tightness of the filter cloth belt 5. When the sludge with different water contents moves to the position between the filter cloth belt 5 and the dewatering roller 3, the sludge with different water contents can be pressed with different forces by adjusting the tightness of the filter cloth belt 5, thereby facilitating the pressing and dewatering of the sludge with different water contents, and conveniently dewatering the sludge with different water contents, and improving the sludge dewatering efficiency.

[0020] As shown in Figure 1 One of the driving rollers 4 is provided with a conveying belt 13 above it. The conveying belt 13 is driven by a motor, and the conveying belt 13 is symmetrically provided with baffles 12 on both sides. When the sludge is conveyed on the conveying belt 13, the sludge falls to the position between the dewatering roller 3 and the driving roller 4. At this time, the sludge is located between the dewatering roller 3 and the filter cloth belt 5, which facilitates the dewatering of the sludge by the dewatering roller 3 and the filter cloth belt 5.

[0021] As shown in Figure 1 Two scrapers are provided on the driving roller 4 away from the conveying belt 13, and the edges of the two scrapers are respectively attached to the adjacent surfaces of the dewatering roller 3 and the filter cloth belt 5, which facilitates the hanging and falling of the pressed sludge.

[0022] The support assembly includes a base 1 horizontally arranged on the support, and two vertical rods 2 are vertically and fixedly arranged on the top end face of the base 1 and located at the positions of the two ends of the dewatering roller 3. The top adjacent sides of the two vertical rods 2 are rotatably connected to the end portions of the two ends of the dewatering roller 3, and one of the vertical rods 2 is provided with a dewatering motor for driving the dewatering roller 3 to rotate.

[0023] A fixed rod is fixedly arranged on the top position of the vertical rod 2 in the length direction perpendicular to the length direction of the vertical rod 2, and the end portions of the fixed rod are rotatably connected to the same end portions of the two driving rollers 4. A motor is arranged on the fixed rod for controlling the two driving rollers 4 to rotate in the same direction. The moving direction of the filter cloth belt 5 is the same as that of the adjacent surface of the dewatering roller 3.

[0024] The control assembly comprises two support rods 6 respectively corresponding to the two control rollers 7 arranged in parallel, a connecting rod 8 arranged along the length direction of the vertical support rod 6 and fixedly connected to the middle positions of the adjacent side surfaces of the different support rods 6, an extension rod 9 arranged in the vertical direction on the center position of the bottom side surface of the connecting rod 8 and fixedly connected to the top end of the connecting rod 8, a buffer spring 10 movably sleeved on the extension rod 9 and connected to the two end portions of the extension rod 9, and a control member arranged on the base 1 and controlling the lifting movement of the bottom end of the extension rod 9 in the vertical direction.

[0025] As shown in Figure 1 , the bottom end of the extension rod 9 is lifted by the control member, and the two support rods 6 are lifted, and the two control rollers 7 are lifted, so as to adjust the tightness of the filter cloth belt 5 sleeved on the two drive rollers 4 and the two control rollers 7, and to facilitate the squeezing and dewatering of the sludge with different water contents.

[0026] The elastic effect of the buffer spring 10 arranged on the extension rod 9 is used to balance the tightness of the filter cloth belt 5 when the sludge suddenly increases and the filter cloth belt 5 is suddenly stretched, so as to avoid the damage of the filter cloth belt 5 caused by too tight.

[0027] The control member comprises a control rod 14 arranged in parallel below the connecting rod 8 and fixedly arranged on the top end surface of the base 1, a bidirectional screw rod 16 penetrating the control slot 15 arranged on the top side surface of the control rod 14, two threaded blocks sleeved on the two end portions of the bidirectional screw rod 16 through threads, and two linkage rods 11 rotatably connected to the bottom of the extension rod 9 and rotatably connected to the top of the different threaded blocks at the bottom, and the bidirectional screw rod 16 is driven by a motor.

[0028] As shown in Figure 2 , the first control member drives the bidirectional screw rod 16 to rotate by the motor, so as to drive the two threaded blocks sleeved on the rod body of the bidirectional screw rod 16 to move close to each other or away from each other, so as to rotate the top of the two linkage rods 11 around the bottom of the extension rod 9, and adjust the lifting movement of the bottom of the extension rod 9.

[0029] The control member comprises a lifting sleeve 17 arranged in the vertical direction and fixedly connected to the bottom of the extension rod 9, a lifting screw rod 18 arranged in the vertical direction and penetrating the bottom end of the lifting sleeve 17 through threads, and a lifting motor 19 fixedly arranged on the top end surface of the base 1 and connected to the output end of the lifting screw rod 18.

[0030] As shown in Figure 3As shown, the second control member directly drives the lifting screw 18 to rotate through the lifting motor 19, which facilitates the lifting sleeve 17 to move up and down on the lifting screw 18, and facilitates the bottom of the telescopic rod 9 to move up and down.

[0031] The lifting sleeve 17 is provided with a limiting structure, which limits the lifting sleeve 17 to move up and down in the vertical direction. For example, the lifting sleeve 17 is provided with a sliding block on the side, and a sliding rod is movably arranged on the sliding block. The sliding rod is parallel to the length direction of the lifting sleeve 17, and the bottom of the sliding rod is fixedly arranged on the top end face of the base 1.

It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application.
