Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-cleaning tubular membranes, and more particularly to a device for self-cleaning tubular membranes. Background Technology
[0002] Currently, as tubular membranes are increasingly used in high-concentration wastewater treatment, such as landfill leachate treatment, special chemical wastewater treatment, oilfield produced water injection, and emulsified oil treatment, as well as in medium- and low-concentration wastewater and material separation, such as tea beverages, fruit juice clarification and concentration, food, biopharmaceuticals, and electrophoretic paint recycling, users are paying more and more attention to cleaning the fouling of the inner filter surface of tubular membranes.
[0003] After prolonged use, some tubular membranes tend to accumulate dirt on their inner walls. Users typically clean this manually with a brush, but this method is laborious, especially when cleaning multiple membranes, which significantly impacts user efficiency. Therefore, we propose a self-cleaning device for tubular membranes to address this issue. Utility Model Content
[0004] The purpose of this invention is to provide a device for self-cleaning tubular membranes to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A device for self-cleaning tubular membranes includes: a workbench, on the top of which is a tubular membrane body and a water pipe, and multiple water spray holes are opened on the outside of the water pipe. Multiple cleaning rings are fixedly connected to the outside of the water pipe. Multiple rollers are arranged on the top of the workbench, and a rotating frame is fixedly connected between two rollers on the same side. An arc-shaped frame is movably abutted against the inside of the rotating frame, and a movable block is fixedly connected to one side of the arc-shaped frame. Rectangular blocks are movably inserted into the inside of two movable blocks, and one side of each of the two rectangular blocks is fixedly connected to both ends of the water pipe.
[0007] Preferably, a water tank and a water pump are fixedly connected to the top of the workbench, and the input end and output end of the water pump are respectively fixedly connected to a No. 1 pipe and a flexible hose, and the other end of the No. 1 pipe is fixedly connected to the inside of the water tank, and the other end of the flexible hose is fixedly connected to the inside of the water pipe.
[0008] Preferably, two insert blocks are slidably connected to the inner side of the movable block, and a spring is fixedly connected to one side of each of the two insert blocks, and the other ends of the two springs are respectively fixedly connected to both sides of the movable block. The rectangular block has slots on both sides that are adapted to the insert blocks, and the outer sides of the two insert blocks are movably inserted into the inner side of the corresponding slots.
[0009] Preferably, the top of the workbench is fixedly connected to multiple brackets, and the inner side of each bracket is rotatably connected to the outer side of the first roller. A motor is fixedly connected to one side of the bracket near the front of the workbench, and the output end of the motor is fixedly connected to one side of the first roller.
[0010] Preferably, the top of the workbench is provided with a sliding groove, a slide plate is slidably connected to the inner side of the sliding groove, and two electric push rods are fixedly connected to the inner wall of one side of the sliding groove. The output ends of the two electric push rods are fixedly connected to the front side of the slide plate. Two hydraulic cylinders are fixedly connected to the top of the slide plate, and clamping blocks are fixedly connected to the output ends of the two hydraulic cylinders. Two guide grooves are provided on the top of the workbench, and the inner sides of the two guide grooves are slidably connected to the outer side of the corresponding moving block.
[0011] Preferably, a controller is fixedly connected to one side of the workbench, and the controller is electrically connected to the electric push rod, the hydraulic cylinder and the motor.
[0012] In this utility model, a device for self-cleaning tubular membranes is described. By placing a water pipe in a suitable position inside the tubular membrane body, and then activating the hydraulic cylinder, the clamping block can fix the tubular membrane body. Next, the inserting block is pushed outward, causing the spring to compress and inserting the rectangular block into the inside of the moving block. Then, the inserting block is no longer pushed, allowing it to enter the slot. At this point, the installation of the device is completed, and the user can then start the water pump and motor.
[0013] In this invention, a device for self-cleaning tubular membranes is described. After the motor is started, the first roller begins to rotate, followed by the rotating frame. This allows the arc-shaped frame to move continuously in the horizontal direction, enabling the water pipe to continuously drive the cleaning ring to clean the inside of the tubular membrane body. This scrapes off the dirt on the inner wall of the tubular membrane body. After the water pump is started, water from the water tank can enter the inside of the tubular membrane body, thus helping the user to rinse the inside of the tubular membrane body. When cleaning different areas, the user can activate the electric push rod to adjust the position of the tubular membrane body to cooperate with the water pipe for cleaning. After the device has finished cleaning, the user can directly remove the tubular membrane body for simple rinsing, which is very convenient.
[0014] This utility model has a reasonable structural design. Through the cooperation between the rotating frame, the first roller and the moving block, the device can automatically drive the cleaning ring to perform horizontal reciprocating cleaning work on the inner wall of the tubular membrane body. This can reduce the user's workload and further improve the user's work efficiency. Attached Figure Description
