Description

Technical Field

[0001] This utility model relates to the technical field of membrane sludge dewatering machines, and in particular to a membrane sludge dewatering machine. Background Technology

[0002] Membrane sludge dewatering machines are important pieces of equipment specifically designed for processing membrane sludge and achieving its dewatering function. They have wide applications in industrial production and environmental protection. In the wastewater treatment industry, the large amount of membrane sludge produced by membrane bioreactors (MBR) needs to be dewatered. Membrane sludge dewatering machines can effectively remove water from the membrane sludge, reducing its volume and weight, making it easier for subsequent transportation and disposal. In industrial production, such as chemical and food processing industries, the membrane sludge produced after the use of some filtration membranes also needs to be dewatered to reduce treatment costs and environmental impact.

[0003] The applicant discovered a Chinese patent, "A PCB Film Removal Dewatering Machine," with publication (announcement) number "CN206540404U." This patent mainly uses spiral blades to transport the film residue from the feed end to the discharge end. During the process, it also drives a movable plate to move left and right between two adjacent fixed plates, cleaning the filter gap between the movable plate and the fixed plate to prevent blockage and affect dewatering. As the outer diameter of the conical shaft gradually increases, it generates huge internal pressure, thereby achieving the purpose of film residue dewatering. However, this patent cannot rinse the feed inlet, and film residue is easily left at the feed inlet, requiring subsequent rinsing with clean water. It does not make good use of the collected wastewater. Therefore, we propose a film residue dewatering machine. Utility Model Content

[0004] The purpose of this invention is to provide a membrane sludge dewatering machine to solve the problems mentioned in the background art, such as the inability to rinse the feed inlet, the easy retention of membrane sludge at the feed inlet, the need for subsequent rinsing with clean water, and the failure to make good use of the collected wastewater.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a membrane sludge dewatering machine, comprising a machine body and a wastewater flushing mechanism, wherein the wastewater flushing mechanism comprises a water pump and a wastewater tank, the water pump is connected to a branch pipe and a high-pressure nozzle through a water pipe, the branch pipe is connected to a feed rack through a support frame, and a filter plate is movably installed inside the wastewater tank.

[0006] As a preferred embodiment, a water outlet pipe is fixedly installed at the bottom of the machine body, a water outlet grid is fixedly installed in the middle section of the machine body, a motor is fixedly installed on the right side of the machine body, and a screw feed rod is fixedly installed at the output end of the motor.

[0007] As a preferred embodiment, the water pump is fixedly installed inside the wastewater tank, one end of the water pipe is fixedly installed at the output end of the water pump, a limiting plate is fixedly installed on the outer wall of the water pipe, the back of the limiting plate is fixedly installed on the front of the machine body, the branch pipe is fixedly installed at the other end of the water pipe, the high-pressure nozzle is fixedly installed on the water outlet of the branch pipe, the support frame is fixedly installed at the bottom of the branch pipe, the upper end of the feed rack is fixedly installed at the lower end of the support frame, and its lower end is fixedly installed at the upper end of the feed inlet of the machine body.

[0008] As a preferred embodiment, the wastewater tank has an inlet on the back, the outlet pipe is inserted into the inlet, the filter plate has a mounting hole through its surface, and the water pipe is inserted into the mounting hole.

[0009] As a preferred embodiment, a material receiving mechanism is provided on the lower left side of the machine body. The material receiving mechanism includes a material feeding guide, a limit frame is fixedly installed at the bottom of the material feeding guide, and a receiving box is slidably connected inside the limit frame.

[0010] As a preferred embodiment, the inside of the feeding guide is provided with a slot, a baffle is inserted into the inside of the slot, a handle is fixedly installed on the left side of the baffle, and an anti-detachment block is fixedly installed on the bottom side away from the handle.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] The wastewater flushing mechanism, through the filter plate, can finely filter the water that has separated from the membrane residue. During this filtration process, smaller impurities in the water are effectively removed. After filtration, the water is then pumped into the branch pipe by the strong suction of the water pump. When the water enters the branch pipe, it is sprayed out through the high-pressure nozzles installed on the branch pipe. The water jets sprayed by these high-pressure nozzles will directly hit the inner wall of the feed rack, preventing membrane residue from remaining in the feed rack. This can greatly reduce the burden of manual cleaning of the feed rack later and improve the efficiency and cleanliness of the entire production process.

[0013] The set-up receiving mechanism enables precise collection of membrane residue using the receiving box. After the receiving box is gradually filled with membrane residue, the staff only needs to insert the special baffle completely into the corresponding slot of the receiving box to intercept the dehydrated membrane residue. This prevents the membrane residue from falling to the ground due to lack of obstruction during the process of changing the receiving box, thus keeping the work area clean, reducing the time and labor costs spent cleaning up membrane residue on the ground, and improving the efficiency and hygiene of the entire workflow.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see the appendix Figure 1 - Appendix Figure 4A membrane sludge dewatering machine includes a body 1 and a wastewater flushing mechanism 6. The wastewater flushing mechanism 6 includes a water pump 601 and a wastewater tank 608. The water pump 601 is connected to a branch pipe 603 and a high-pressure nozzle 604 via a water pipe 602. The branch pipe 603 is connected to a feed rack 606 via a support frame 605. A filter plate 610 is movably installed inside the wastewater tank 608. A water outlet pipe 2 is fixedly installed at the bottom of the body 1. A water outlet grille 5 is fixedly installed in the middle section of the body 1. A motor 3 is fixedly installed on the right side of the body 1. A screw feed rod 4 is fixedly installed at the output end of the motor 3. The water pump 601 is fixedly installed inside the wastewater tank 608. One end of the water pipe 602 is fixedly installed on the water pump 601. At the output end, a limiting plate 607 is fixedly installed on the outer wall of the water pipe 602. The back of the limiting plate 607 is fixedly installed on the front of the machine body 1. The branch pipe 603 is fixedly installed at the other end of the water pipe 602. The high-pressure nozzle 604 is fixedly installed on the water outlet of the branch pipe 603. The support frame 605 is fixedly installed at the bottom of the branch pipe 603. The upper end of the feed rack 606 is fixedly installed at the lower end of the support frame 605, and its lower end is fixedly installed at the upper end of the feed inlet of the machine body 1. The back of the wastewater tank 608 has a water inlet 609. The water outlet pipe 2 is inserted into the inside of the water inlet 609. The surface of the filter plate 610 has a through mounting hole 611, and the water pipe 602 is inserted into the inside of the mounting hole 611.

[0023] The inner wall of the wastewater tank 608 is equipped with a placement block for placing the filter plate 610, which makes it easy to remove the filter plate 610 from the wastewater tank 608 for cleaning. The water pump 601 is located in the wastewater tank 608, which draws the wastewater from the upper layer with fewer impurities, and provides better protection for the water pump 601 and the high-pressure nozzle 604.

[0024] Specifically, the water separated from the membrane residue can be filtered through the filter plate 610 to remove smaller impurities. Then, the water is pumped into the branch pipe 603 by the water pump 601 and sprayed out through the high-pressure nozzle 604 to rinse the inner wall of the feed rack 606, so as to avoid membrane residue remaining in the feed rack 606 and reduce the burden of manual cleaning later. Example

[0025] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 Furthermore, based on Embodiment 1, a receiving mechanism 7 is provided on the lower left side of the machine body 1. The receiving mechanism 7 includes a feeding guide 701. A limiting frame 702 is fixedly installed at the bottom of the feeding guide 701. A receiving box 703 is slidably connected inside the limiting frame 702. A slot 704 is opened inside the feeding guide 701. A baffle 705 is inserted into the slot 704. A handle 707 is fixedly installed on the left side of the baffle 705, and an anti-detachment block 706 is fixedly installed on the bottom side away from the handle 707.

[0026] The anti-detachment block 706 is located at the bottom of the baffle 705 away from the handle 707. When the baffle 705 is pulled out of the slot 704, it can prevent the baffle 705 from completely detaching, while ensuring that the membrane residue flows out smoothly from the feed guide 701.

[0027] Specifically, the membrane residue can be accurately collected through the receiving box 703. When the receiving box 703 is full, the baffle 705 can be fully inserted into the slot 704 to intercept the membrane residue after dewatering, thus preventing the membrane residue from falling to the ground when the receiving box 703 is replaced.

[0028] Working principle of this utility model: This utility model is a membrane sludge dewatering machine. The membrane sludge to be dewatered is poured into the machine body 1 through the feed inlet. The membrane sludge enters the machine body 1 along the feed rack 606 and is squeezed to the left by the screw feed rod 4. The water in the membrane sludge is squeezed out and flows out from the outlet grid 5, and enters the wastewater tank 608 along the outlet pipe 2. The impurities in the wastewater are filtered by the filter plate 610 and settle at the bottom of the wastewater tank 608. The dewatered membrane sludge falls into the receiving box 70 along the discharge guide 701. Inside step 3, after the receiving box 703 is full, hold the handle 707 and insert the baffle 705 along the direction of the slot 704 to intercept the membrane residue. Then, remove the receiving box 703 and replace it. After the membrane residue is discharged, start the water pump 601 to draw the wastewater inside the wastewater tank 608 into the branch pipe 603 through the water pipe 602. Then, spray it out through the high-pressure nozzle 604 to rinse the feed rack 606 and flush the remaining membrane residue into the machine body 1 for dewatering.
