Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to an ultrafiltration membrane cleaning device. Background Technology

[0002] After prolonged use, impurities filtered by the ultrafiltration membrane will adhere to the membrane, affecting its filtration efficiency. Therefore, it is necessary to clean the ultrafiltration membrane regularly to remove these deposits.

[0003] The cleaning process for ultrafiltration membranes includes a primary rinse, soaking, and a secondary rinse. The primary rinse removes most of the deposits on the membrane surface. Soaking uses chemical agents to remove stubborn deposits. Finally, the secondary rinse removes the chemical residues. Ultrafiltration membranes require frequent cleaning, and the above steps are relatively tedious and labor-intensive.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an ultrafiltration membrane cleaning device to improve the automation level of ultrafiltration membrane cleaning.

[0006] The technical solution of this utility model is as follows:

[0007] The ultrafiltration membrane cleaning device includes:

[0008] Cleaning tank with an opening at the top;

[0009] A support frame is mounted on the cleaning tank; a transverse rack and a transverse slide rail are horizontally arranged in the same direction on the support frame; a transverse slider is slidably mounted on the transverse slide rail.

[0010] A crossbar connects to the horizontal slider;

[0011] A vertical rod connects to the horizontal rod; a vertical rack and a vertical slide rail are vertically arranged on the vertical rod; a vertical slider is slidably arranged on the vertical slide rail;

[0012] A connecting plate is provided for connecting the vertical slider; the connecting plate is equipped with grippers.

[0013] The horizontal slider is equipped with a first motor, which engages with the horizontal rack via a gear shaft. The vertical slide rail is equipped with a second motor, which engages with the vertical rack via a gear shaft.

[0014] A further technical solution is that the cleaning tank is divided into a soaking chamber and a rinsing chamber; a rinsing pipe is installed in the rinsing chamber.

[0015] A further technical solution is that the flushing pipe is connected to a water pump; the flushing pipe extends into the pipe body inside the flushing chamber and has a spray hole; the spray hole is connected to a spray pipe.

[0016] A further technical solution is that the spray nozzle is arranged radially around the axis of the flushing pipe.

[0017] A further technical solution is that the bracket is also provided with limiting blocks; the two limiting blocks are respectively provided at both ends of the transverse slide rail.

[0018] A further technical solution is that two transverse slide rails are arranged in parallel, and transverse sliders are respectively provided on the two transverse slide rails; the two transverse slide rails are connected to the crossbar.

[0019] A further technical solution is that two crossbars are arranged in parallel.

[0020] A further technical solution is that two vertical rods are arranged in parallel; vertical slide rails and vertical sliders are respectively provided on the two vertical rods; the two vertical sliders are simultaneously connected to the connecting plate.

[0021] A further technical solution is to provide a reinforcing rod; the reinforcing rod is arranged parallel to the connecting plate; the reinforcing rod is connected to the vertical slider.

[0023] The beneficial technical effects of this utility model are as follows:

[0024] (1) In the ultrafiltration membrane cleaning device of this utility model, the ultrafiltration membrane is fixed on a bracket on the cleaning tank by grippers. The bracket is also equipped with a motor rack and pinion transmission mechanism. During primary cleaning, soaking, and secondary cleaning, only the first and second motors need to be controlled. The meshing between the first motor and the horizontal rack, and the meshing between the second motor and the vertical rack, controls the horizontal and vertical movement of the grippers and the ultrafiltration membrane held by the grippers, thus placing the ultrafiltration membrane into the cleaning tank for cleaning. The above actions do not require manual intervention from operators, achieving fully mechanical control of ultrafiltration membrane cleaning and improving the automation level of ultrafiltration membrane cleaning. Combined with PLC and other controllers, fully automatic cleaning of ultrafiltration membranes can be achieved, reducing manpower input and improving the efficiency of large-scale ultrafiltration membrane cleaning.

[0025] (2) Furthermore, the cleaning chamber is divided into an soaking chamber and a rinsing chamber. The ultrafiltration membrane can be moved to different positions in the cleaning chamber by the first motor and the second motor, so that the soaking / rinsing steps of the ultrafiltration membrane can be performed without switching the clamping position of the ultrafiltration membrane on the support, thereby improving the cleaning efficiency of the ultrafiltration membrane.

[0026] (3) Furthermore, there are two horizontal bars and two vertical bars, and a reinforcing bar is provided between the two vertical sliders to enhance the overall structural strength of the ultrafiltration membrane cleaning device and improve the stability of the ultrafiltration membrane during movement.

[0034] Figure 1 A three-dimensional structural schematic diagram of an ultrafiltration membrane cleaning apparatus according to an embodiment of the present disclosure is shown. Figure 2 A partially enlarged view of an ultrafiltration membrane cleaning apparatus according to an embodiment of this disclosure is shown at point A. Please refer to... Figure 1 and Figure 2 The ultrafiltration membrane cleaning device includes a cleaning tank 1 with an opening at the top. A support 2 is mounted on the cleaning tank 1. A horizontal rack 21 and a horizontal slide rail 22 are arranged horizontally in the same direction on the support 2. A horizontal slider 23 is slidably mounted on the horizontal slide rail 22. A horizontal bar 3 connects to the horizontal slider 23. A vertical bar 4 connects to the horizontal bar 3. A vertical rack 41 and a vertical slide rail 42 are arranged vertically on the vertical bar 4. A vertical slider 43 is slidably mounted on the vertical slide rail 42. A connecting plate 5 connects to the vertical slider 43. A clamp 51 is provided on the connecting plate 5 to fix the ultrafiltration membrane.

[0035] A first motor 231 is mounted on the horizontal slider 23. The first motor 231 meshes with the horizontal rack 21 via a gear shaft 232. A second motor 431 is mounted on the vertical slide rail 42. The second motor 431 meshes with the vertical rack 41 via a gear shaft 232. For primary cleaning, soaking, and secondary cleaning, only the first motor 231 and the second motor 431 need to be controlled. The meshing between the first motor 231 and the horizontal rack 21, and the meshing between the second motor 431 and the vertical rack 41, controls the gripper 51 and the ultrafiltration membrane held by the gripper 51 to move laterally and vertically, placing the ultrafiltration membrane into the cleaning tank 1 for cleaning. During the initial cleaning, soaking, and secondary cleaning processes, only the first motor 231 and the second motor 431 need to be controlled. The engagement between the first motor 231 and the horizontal rack 21, and the engagement between the second motor 431 and the vertical rack 41, controls the gripper 51 and the ultrafiltration membrane it holds to move laterally and vertically, thus placing the ultrafiltration membrane into the cleaning tank 1 for cleaning. These actions require no manual intervention from operators, achieving fully mechanical control of the ultrafiltration membrane cleaning process and improving its automation level. Combined with PLC and other controllers, fully automated ultrafiltration membrane cleaning can be achieved, reducing manpower and improving the efficiency of large-volume ultrafiltration membrane cleaning.

[0036] Figure 3A schematic diagram of the internal structure of the rinsing chamber in an ultrafiltration membrane cleaning apparatus according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3 The cleaning tank 1 is divided into an soaking chamber 11 and a rinsing chamber 12. A rinsing pipe 121 is installed in the rinsing chamber 12. A cleaning agent can be injected into the soaking chamber 11, and the ultrafiltration membrane can be soaked in the cleaning agent after being placed in the soaking chamber 11. After the ultrafiltration membrane is placed in the rinsing chamber 12, liquid can be sprayed from the rinsing pipe 121 to rinse the ultrafiltration membrane. In some embodiments, a drain hole (not shown in the figure) connecting to the rinsing chamber 12 can be provided on the cleaning tank 1 to discharge the rinsing liquid and any adhering substances rinsed off the ultrafiltration membrane.

[0037] Preferably, the flushing pipe 121 is connected to a water pump. The flushing pipe 121 extends into the pipe body inside the flushing chamber 12 and has a spray hole 123. A spray pipe 122 is inserted into the spray hole 123. The spray pipe 122 guides the liquid in the flushing pipe 121 to spray out and directionally flush the ultrafiltration membrane.

[0038] More preferably, the nozzles 122 are arranged radially around the axis of the flushing pipe 121. This allows for the spraying of liquid over a wide area, eliminating blind spots in the flushing process and ensuring thorough flushing of the ultrafiltration membrane.

[0039] Please refer to Figure 1 and Figure 2 Two horizontal slide rails 22 are arranged in parallel, and horizontal sliders 23 are respectively installed on the two horizontal slide rails 22. The two horizontal slide rails 22 are connected to the crossbar 3. The two horizontal slide rails 22 support the crossbar 3 together, improving the stability of the crossbar 3 when it moves along the horizontal slide rails 22. The two horizontal bars 3 are arranged in parallel to reduce the jitter of the horizontal sliders 23 when they slide along the horizontal slide rails 22.

[0040] Preferably, two vertical rods 4 are arranged in parallel. Each of the two vertical rods 4 is equipped with a vertical slide rail 42 and a vertical slider 43. Both vertical sliders 43 are connected to the connecting plate 5. The cleaning tank 1 is also equipped with a horizontal slide rail 22 and a horizontal slider 23. The end of the vertical rod 4 furthest from the horizontal rod 3 is connected to the horizontal slider 23 on the cleaning tank 1. The horizontal slider 23 on the cleaning tank 1 and the horizontal slide rail 22 on the bracket 2 work together to support the horizontal rod 3 and the vertical rod 4, further improving the stability of the horizontal rod 3 when it moves along the horizontal slide rail 22.

[0041] More preferably, a reinforcing rod 6 is also provided. The reinforcing rod 6 is arranged parallel to the connecting plate 5. The reinforcing rod 6 is connected to the vertical slider 43.

[0042] Please refer to Figure 1 and Figure 2 The bracket 2 is also equipped with limit blocks 221. The two limit blocks 221 are respectively set at both ends of the transverse slide rail 22. The limit blocks 221 restrict the sliding stroke of the transverse slider 23 and prevent the transverse slider 23 from falling off the transverse slide rail 22.

[0043] Preferably, the gripper 51 includes a cylinder 511 mounted on the connecting plate 5, a gripper portion 512 of the hinged cylinder 511, and a connecting rod 513 of the hinged gripper portion 512. The connecting rod 513 is also rotatably connected to the telescopic rod of the cylinder 511. At least two gripper portions 512 are provided. All gripper portions 512 are evenly arranged around the axis of the telescopic rod of the cylinder 511. When the cylinder 511 is activated, the telescopic rod of the cylinder 511 extends or retracts. The moving telescopic rod drives all gripper portions 512 to rotate around the cylinder 511 via the connecting rod 513, thereby clamping or releasing the ultrafiltration membrane.

[0044] The specific workflow of this utility model is as follows:

[0045] When cleaning the ultrafiltration membrane, first, soaking liquid is placed in the soaking chamber 11. Then, the operator or feeding device moves the ultrafiltration membrane to the gripper 51 position. The cylinder 511 is activated, and its extension rod moves to open the gripper 512. The ultrafiltration membrane moves between all the grippers 512, and the extension rod of the cylinder 511 moves to retract the grippers 512 to clamp the ultrafiltration membrane. Then, the first motor 231 and the second motor 431 are activated. The first motor 231 drives the gear shaft 232, which meshes with the transverse rack 21, to rotate, causing the transverse slider 23 and the crossbar 3 to move along the transverse slide rail 22. The second motor 431 drives the gear shaft 232, which meshes with the vertical rack 41, to rotate, causing the vertical slider 43 and the connecting plate 5 to move along the vertical slide rail 42. The first motor 231 and the second motor 431 are started sequentially. First, the ultrafiltration membrane held by the gripper 51 is moved into the rinsing chamber 12 for a first rinse. Then, the ultrafiltration membrane is moved into the soaking chamber 11 for soaking. Finally, the ultrafiltration membrane is moved into the rinsing chamber 12 for a second rinse. After the ultrafiltration membrane is moved into the rinsing chamber 12, the water pump drives the rinsing liquid to spray out along the nozzle 122 and the nozzle 123 to rinse the ultrafiltration membrane that has been moved into the rinsing chamber 12.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
