Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a silt and sewage separation device. Background Technology

[0002] In the field of wastewater treatment, sediment separation is a crucial step. Existing sediment separation devices mostly employ a single filter cloth combined with a pressing structure for separation, but these methods generally suffer from several problems. For example, the filter cloth tension adjustment is rudimentary, often requiring manual adjustment, which cannot accurately adjust according to the real-time stress state of the filter cloth. This can easily lead to the filter cloth becoming too loose or too tight, affecting separation uniformity and even causing filter cloth damage. Furthermore, the connection structure between the filter cloth and the roller is complex, requiring specialized tools for disassembly and assembly, resulting in low maintenance efficiency and difficulty meeting the needs of continuous operation. Insufficient assembly precision between the filter cloth roller and connecting components can easily cause misalignment and wobbling, leading to filter cloth deviation, wear, and shortened equipment lifespan. Therefore, there is an urgent need for a sediment separation device that offers precise tension adjustment, convenient disassembly and assembly, and stable separation performance. Utility Model Content

[0003] The purpose of this invention is to provide a mud and wastewater separation device to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides a silt and wastewater separation device, including a mounting bracket, a filter cloth, a guide roller assembly, and a pressure roller. The guide roller assembly and the pressure roller are both mounted on the mounting bracket. The filter cloth is wound around the inner circumference of the guide roller assembly. The pressure roller is positioned corresponding to the material bearing surface of the filter cloth. The device also includes a tensioning mechanism and a connector. The tensioning mechanism is mounted on the mounting bracket and includes a slider and a power component. The back of the slider is fixedly connected to the tensioning bracket. The power component drives the slider to move axially along the guide rail to adjust the tension of the filter cloth. The connector is located at both ends of the filter cloth and includes a detachable plug and a socket. The connecting end of the plug is detachably connected to the end of the filter cloth roll, and the socket abuts against the tensioning bracket.

[0005] Preferably, the tensioning mechanism is arranged horizontally below the filter cloth and is assembled perpendicularly to the mounting bracket. The power components of the tensioning mechanism include a lead screw, a guide rail, a coupling, and a stepper motor embedded in the mounting bracket. The upper end of the slider has a threaded hole that mates with the lead screw, and the lower end has a guide hole that is adapted to slide along the guide rail. The back of the slider is fixedly connected to the tensioning bracket by bolts. The stepper motor is connected to the lead screw through the coupling to drive the slider to move axially along the guide rail.

[0006] Preferably, the plug includes a connecting end, a protrusion and a latch on the outer peripheral wall, and the socket includes a free end, a T-shaped slot on the outer wall of the free end and a rotating handle hinged to the outer wall of the socket. The plug's latch is aligned with the T-shaped slot on the free end of the socket and inserted. The rotating handle is rotated to drive the free end of the socket to rotate synchronously, so that the latch slides and engages along the circumference of the T-shaped slot, thereby achieving the positioning connection between the plug and the socket.

[0007] Preferably, the tensioning bracket has an installation hole that matches the size of the plug connection end. The connection end of the plug passes through the installation hole and is positioned and connected to the tensioning bracket by abutting against the end face of the installation hole through a protrusion on the outer peripheral wall of the plug. The plug's buckle is located on the outside of the tensioning bracket.

[0008] Preferably, the filter cloth includes an upper filter cloth and a lower filter cloth. A tensioning mechanism is provided on the same side of the upper filter cloth and the lower filter cloth respectively. The sliders of the two tensioning mechanisms are fixedly connected to the corresponding tensioning brackets, and the tension of the filter cloth is adjusted independently by the two tensioning mechanisms.

[0009] Preferably, the axes of the plug, socket, mounting hole, and filter cloth roll are collinear.

[0010] Therefore, the beneficial effects of this utility model using the above-mentioned mud and sand wastewater separation device are as follows: 1. The silt and sand are separated by the matching of the pressure roller and the filter cloth. With the double-layer filter cloth design and independent tensioning mechanism, the tension can be precisely adjusted according to the stress on the filter cloth, avoiding uneven separation and filter cloth damage caused by loose or too tight filter cloth. This significantly improves the efficiency of silt and wastewater separation and can be flexibly adapted to different installation scenarios.

[0011] 2. The connector adopts a combination structure of T-shaped slot, buckle and rotating handle. With the detachable connection between the plug and the filter cloth roll, the filter cloth can be replaced quickly without complicated tools. The abutment limit design between the protrusion and the mounting hole simplifies the positioning and installation process of the plug and tension bracket and reduces maintenance costs.

[0012] 3. The plug, socket, mounting hole and filter cloth roll are designed to be on the same axis, which avoids offset and shaking when the roll rotates, reduces component wear and extends the overall service life of the equipment.

[0013] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1-4As shown, the present invention provides a silt and wastewater separation device, including a mounting bracket 1, a filter cloth 2, a guide roller group 3, and a pressure roller 4. The guide roller group 3 and the pressure roller 4 are both mounted on the mounting bracket 1. The filter cloth 2 is wound around the inner circumference of the guide roller group 3. The pressure roller 4 is set corresponding to the material bearing surface of the filter cloth 2 to achieve silt pressing and separation. It also includes a tensioning mechanism 5 and a connector 6. The tensioning mechanism 5 is mounted on the mounting bracket 1 and includes a slider 51 and a power component. The back of the slider 51 is fixedly connected to the tensioning bracket 7. The power component drives the slider 51 to move axially along the guide rail 53 to adjust the tension of the filter cloth 2 in real time and avoid the filter cloth 2 from loosening and affecting the separation effect. The connector 6 is located at both ends of the filter cloth 2 and includes a detachable plug 61 and a socket 62. The connecting end 611 of the plug 61 is detachably connected to the end of the filter cloth roll, and the socket 62 abuts against the tensioning bracket 7 to realize the quick disassembly and assembly and stable fixation of the filter cloth roll.

[0019] Specifically, the tensioning mechanism 5 is arranged horizontally below the filter cloth 2 and is assembled perpendicularly to the mounting bracket 1. The power components of the tensioning mechanism 5 include a lead screw 52, ​​a guide rail 53, a coupling 54, and a stepper motor 55 embedded in the mounting bracket 1. The upper end of the slider 51 has a threaded hole that is threaded to the lead screw 52, ​​and the lower end has a guide hole that is slidably adapted to the guide rail 53. The back of the slider 51 is fixedly connected to the tensioning bracket 7 by bolts. The stepper motor 55 is connected to the lead screw 52 through the coupling 54 to drive the slider 51 to move axially along the guide rail 53, so as to achieve precise and controllable adjustment of the tension. The plug 61 includes a connecting end 611, a protrusion 612 on the outer peripheral wall, and a buckle 613. The socket 62 includes a free end 621, a T-shaped groove 622 on the outer wall of the free end 621, and a rotating handle 623 hinged to the outer wall of the socket 62. The buckle 613 of the plug 61 is aligned with the T-shaped groove 622 of the free end 621 of the socket 62 and inserted. The rotating handle 623 is rotated to drive the free end 621 of the socket 62 to rotate synchronously, so that the buckle 613 slides and engages around the T-shaped groove 622, realizing quick positioning, connection and disassembly of the plug 61 and the socket 62, which facilitates the replacement of the filter cloth 2 and equipment maintenance. The tensioning bracket 7 has an installation hole that matches the size of the connector end 611 of the plug 61. The connector end 611 of the plug 61 passes through the installation hole, and the protrusion 612 on the outer peripheral wall of the plug 61 abuts against the end face of the installation hole to limit its positioning and connection to the tensioning bracket 7. The buckle 613 of the plug 61 is located on the outside of the tensioning bracket 7 to ensure the docking accuracy and connection stability of the plug 61 and the socket 62. The filter cloth 2 includes an upper filter cloth 21 and a lower filter cloth 22. A tensioning mechanism 5 is set on the same side of the upper filter cloth 21 and the lower filter cloth 22 respectively. The sliders 51 of the two tensioning mechanisms 5 are fixedly connected to the corresponding tensioning brackets 7, and the two tensioning mechanisms 5 independently adjust the tension of the filter cloth 2 to adapt to the force difference of the double-layer filter cloth 2 under different working conditions and improve the uniformity of the separation effect.

[0020] In addition, the axes of plug 61, socket 62, mounting hole and filter cloth roll are collinear, ensuring smooth and unbiased rotation of the filter cloth roll, preventing filter cloth 2 from running off-center or wearing out, and extending the service life of the equipment.

[0021] Working principle: Sludge and wastewater are evenly transported to the material bearing surface of the upper filter cloth 21. A preset pressure is applied to the upper filter cloth 21 by the pressure roller 4, causing the wastewater to pass through the pores of the filter cloth 2 and be discharged. The upper filter cloth 21 first traps large particles of sludge, while the wastewater permeates to the lower filter cloth 22 for secondary fine filtration. This double filtration improves the separation purity. The guide roller group 3 provides support and guidance for the filter cloth 2, ensuring stable circulation. During operation, when the filter cloth 2 becomes loose due to sludge adhesion or long-term use, the stepper motor 55 receives a signal and drives the lead screw 52 to rotate through the coupling 54, causing the slider 51 to move axially along the guide rail 53, thereby pulling the tensioning bracket 7. This allows for real-time and precise adjustment of the tension of filter cloth 2. If there is a difference in force between the upper filter cloth 21 and the lower filter cloth 22, the two tensioning mechanisms 5 can operate independently to adjust the tension of the corresponding filter cloths, ensuring a uniform and stable double-layer filtration effect. The connector 6 uses the T-shaped slot 622 of the plug 61 and socket 62 to ensure a secure connection between the filter cloth roll and the tensioning bracket 7. When the filter cloth 2 is damaged or aged, the handle 623 can be rotated in the opposite direction to disengage the buckle 613 from the T-shaped slot 622, disconnecting the plug 61 from the socket 62. After disassembling the filter cloth roll and replacing it with a new filter cloth 2, the parts can be reassembled and fixed in the original way to quickly restore the equipment to operation.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
