Description

Technical Field

[0001] This utility model relates to the field of cleaning waste liquid recycling technology, and in particular to a cleaning liquid recycling device for membrane cleaning. Background Technology

[0002] Plastic film is widely used in agriculture. Among plastic films, there are sheet-type plastic films, mainly used for planting special fruits, vegetables and other plants to change the planting environment. If plastic film is not recycled after use, it will remain in the soil. Due to its slow degradation rate, it will affect the soil environment and crop production. Therefore, it needs to be recycled. After recycling, it needs to be cleaned. In order to save water resources, the cleaning solution after cleaning the film needs to be recycled. Therefore, cleaning solution recycling equipment is required.

[0003] Existing cleaning fluid recovery equipment typically requires filtering out solid impurities mixed in with the cleaning fluid. Therefore, the recovery equipment usually contains a filter screen. To avoid the problem of poor filtration effect due to impurities clogging the filter screen, a sludge removal structure is usually set in the equipment. A motor drives a pusher plate to remove impurities from the filter screen. However, the above structure requires additional electricity, which will undoubtedly increase the electricity cost. In view of this, a cleaning fluid recovery equipment for membrane cleaning is provided to overcome the above defects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cleaning fluid recovery device for membrane cleaning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a membrane cleaning fluid recovery device, comprising a recovery tank with a drain valve at one bottom side, a water inlet on one side of the top of the recovery tank, and a filter screen installed inside the recovery tank. A rotating shaft is rotatably arranged inside the recovery tank, and blades are fixedly installed on the rotating shaft. The blades are located directly below the water inlet. A limiting shaft is rotatably arranged at the center of the top wall of the recovery tank. A first scraper is fixedly sleeved on the limiting shaft. A second scraper is arranged on one side of the first scraper, and a third scraper is arranged on one side of the second scraper. The first scraper, the second scraper, and the third scraper are all slidably connected to the top of the filter screen. A slag discharge port is opened on one side of the recovery tank. The rotating shaft is drivenly connected to the limiting shaft.

[0006] As a further description of the above technical solution: a first bevel gear is fixedly installed at one end of the rotating shaft, and a second bevel gear is fixedly sleeved on the limiting shaft, with the first bevel gear and the second bevel gear meshing and connected.

[0007] As a further description of the above technical solution: bearings are fixedly installed at the center of the inner side wall and the top wall of the recycling bin. One end of the rotating shaft and the limiting shaft are respectively fixedly inserted into the inner ring of the two bearings, which can facilitate the reasonable rotation and installation of the rotating shaft and the limiting shaft in the recycling bin and avoid the problem of motion interference.

[0008] As a further description of the above technical solution: there are multiple rotating shafts, and the multiple rotating shafts are fixedly installed at equal intervals around the outside of the rotating shaft. The width of the blade is slightly smaller than the width of the water inlet. The arrangement of multiple rotating shafts can increase the contact area with the cleaning fluid, thereby facilitating the rotation of the rotating shaft.

[0009] As a further description of the above technical solution: the first scraper, the second scraper and the third scraper are all provided with multiple filter holes for filtering wastewater.

[0010] As a further description of the above technical solution: a fixed cavity is provided inside the first scraper, and a T-shaped component is slidably disposed in the fixed cavity. The other end of the T-shaped component slidably passes through the first scraper and is fixedly connected to the second scraper. A support spring is provided on one side of the T-shaped component, and the other end of the support spring is fixedly installed on the inner side wall of the fixed cavity. During the movement of the first scraper, the second scraper, and the third scraper, the second scraper will drive the T-shaped component to stretch the support spring due to centrifugal force and move outward from the first scraper within the fixed cavity. This can increase the stroke of the second scraper, allowing the second scraper to drive the third scraper to gather the impurities in the four corners of the recycling box, thereby improving the cleaning effect of impurities.

[0011] As a further description of the above technical solution: two guide rods are symmetrically fixedly installed inside the fixed cavity, and the T-shaped piece is slidably sleeved on the guide rods, so that the T-shaped piece can slide along the direction set by the guide rods, avoiding the problem of movement deviation.

[0012] As a further description of the above technical solution: a sealing sheet is fixedly installed on one side of the second scraper, and the other side of the sealing sheet is slidably connected to one side of the first scraper. By opening the sealing sheet, the filtered cleaning liquid can be discharged, which can be easily recycled.

[0013] This utility model has the following beneficial effects:

[0014] This utility model designs a membrane cleaning fluid recovery device. By injecting a large amount of cleaning fluid for cleaning membranes into the recovery tank through the water inlet, the cleaning fluid impacts the blades and drives the rotating shaft and the first bevel gear to rotate. At the same time, the first bevel gear drives the second bevel gear, the limiting shaft, the first scraper, the second scraper, and the third scraper to rotate, gathering the impurities left by the filter screen at the top and discharging them through the slag outlet to a designated location outside the recovery tank. This conveniently completes the cleaning of impurities. Furthermore, the rotation of the above components does not require an additional drive source; it only relies on the pushing force of the cleaning fluid injected into the recovery tank, greatly saving processing costs.

[0015] The membrane cleaning fluid recovery device designed in this utility model has the following characteristics: during the movement of the first scraper, the second scraper, and the third scraper, the second scraper will drive the T-shaped component to stretch the support spring due to centrifugal force and move outward from the first scraper within the fixed cavity. This increases the stroke of the second scraper and allows the second scraper to drive the third scraper to gather the impurities in the four corners of the recovery box, thereby improving the cleaning effect of impurities.

[0022] Reference Figure 1-4This utility model provides a membrane cleaning fluid recovery device, which includes a recovery tank 1 with a drain valve 19 on one side of the bottom, a water inlet 2 on one side of the top of the recovery tank 1, and a filter screen 10 installed inside the recovery tank 1. A rotating shaft 3 is rotatably installed inside the recovery tank 1, and a blade 4 is fixedly installed on the rotating shaft 3. The blade 4 is located directly below the water inlet 2. A limiting shaft 5 is rotatably installed at the center of the top wall inside the recovery tank 1. A first scraper 6 is fixedly sleeved on the limiting shaft 5. A second scraper 7 is provided on one side of the first scraper 6, and a third scraper 8 is provided on one side of the second scraper 7. The first scraper 6, the second scraper 7, and the third scraper 8 are all slidably connected to the top of the filter screen 10. A slag discharge port 9 is opened on one side of the recovery tank 1. The rotating shaft 3 is connected to the limiting shaft 5 in a transmission manner.

[0023] A first bevel gear 11 is fixedly installed at one end of the rotating shaft 3, and a second bevel gear 12 is fixedly sleeved on the limiting shaft 5. The first bevel gear 11 and the second bevel gear 12 are meshed and connected.

[0024] In practice, a large amount of cleaning fluid for cleaning membranes is injected into the recovery tank 1 through the water inlet 2. During this process, the cleaning fluid impacts the blades 4 and drives the rotating shaft 3 and the first bevel gear 11 to rotate. At the same time, the first bevel gear 11 drives the second bevel gear 12 and the limiting shaft 5 to rotate. This causes the limiting shaft 5 to drive the first scraper 6, the second scraper 7, and the third scraper 8 to move, gathering the impurities left by the filter screen 10 at the top and discharging them through the slag outlet 9 to a designated location outside the recovery tank 1. This conveniently completes the cleaning of impurities. Furthermore, the rotation of the first scraper 6, the second scraper 7, and the third scraper 8 does not require an additional drive source; it only requires the pushing force of the cleaning fluid injected into the recovery tank 1, which greatly saves processing costs.

[0025] As a further implementation of the above technical solution: bearings are fixedly installed at the center of the inner side wall and top wall of the recycling bin 1, and one end of the rotating shaft 3 and the limiting shaft 5 are respectively fixedly inserted into the inner ring of the two bearings. This allows the rotating shaft 3 and the limiting shaft 5 to be easily and reasonably rotated and installed in the recycling bin 1, avoiding the problem of motion interference.

[0026] As a further implementation of the above technical solution: Multiple rotating shafts 3 are installed at equal intervals around the outer circumference of the rotating shafts 3, and the width of the blades 4 is slightly smaller than the width of the water inlet 2. The arrangement of multiple rotating shafts 3 increases the contact area with the cleaning fluid, thereby facilitating the rotation of the rotating shafts 3.

[0027] As a further implementation of the above technical solution: the first scraper 6, the second scraper 7 and the third scraper 8 are each provided with a plurality of filter holes 13 for filtering wastewater.

[0028] As a further implementation of the above technical solution: a fixed cavity 14 is provided inside the first scraper 6, and a T-shaped piece 15 is slidably arranged in the fixed cavity 14. The other end of the T-shaped piece 15 slides through the first scraper 6 and is fixedly connected to the second scraper 7. A support spring 16 is provided on one side of the T-shaped piece 15, and the other end of the support spring 16 is fixedly installed on the inner side wall of the fixed cavity 14.

[0029] In specific implementation, based on the above implementation, during the movement of the first scraper 6, the second scraper 7 and the third scraper 8, the second scraper 7 will drive the T-shaped part 15 to stretch the support spring 16 due to centrifugal force and move outward from the first scraper 6 within the fixed cavity 14. This can increase the stroke of the second scraper 7, allowing the second scraper 7 to drive the third scraper 8 to gather the impurities in the four corners of the recycling box 1, thereby improving the cleaning effect of impurities.

[0030] As a further implementation of the above technical solution: two guide rods 17 are symmetrically fixedly installed inside the fixed cavity 14, and the T-shaped piece 15 is slidably sleeved on the guide rods 17. This allows the T-shaped piece 15 to slide along the direction set by the guide rods 17, avoiding the problem of movement deviation.

[0031] A sealing plate 18 is fixedly installed on one side of the second scraper 7, and the other side of the sealing plate 18 is slidably connected to one side of the first scraper 6. By opening the sealing plate 18, the filtered cleaning liquid can be discharged, making it easy to recycle.

[0032] Working principle:

[0033] Before using this utility model, all electrical appliances involved in the recycling bin 1 need to be connected to an external power source, or an electrical box needs to be installed in an area of ​​the recycling bin 1 that does not obstruct other components. Then, the electrical box is connected to the electrical appliances through a line to supply power to the electrical appliances, thereby ensuring the normal operation of the electrical appliances. Since connecting the electrical appliances to an external power source or setting up an electrical box for power supply is existing technology and is not a problem that needs to be solved in the background technology of this specification, it will not be explained in detail.

[0034] In use, a large amount of cleaning solution for cleaning membranes is first injected into the recovery tank 1 through the water inlet 2. During this process, the cleaning solution will impact the blades 4 and drive the rotating shaft 3 and the first bevel gear 11 to rotate. At the same time, the first bevel gear 11 will drive the second bevel gear 12 and the limiting shaft 5 to rotate, so that the limiting shaft 5 drives the first scraper 6, the second scraper 7 and the third scraper 8 to move, which will gather the impurities left by the filter screen 10 and discharge them to the designated position outside the recovery tank 1 through the slag discharge port 9. This can easily complete the cleaning of impurities. At the same time, the rotation of the first scraper 6, the second scraper 7 and the third scraper 8 does not require an additional drive source. It only needs to be driven by the cleaning solution injected into the recovery tank 1, which greatly saves processing costs.

[0035] During the movement of the first scraper 6, the second scraper 7, and the third scraper 8, the second scraper 7 will cause the T-shaped part 15 to stretch the support spring 16 due to centrifugal force and move outward from the first scraper 6 within the fixed cavity 14. This can increase the stroke of the second scraper 7, allowing the second scraper 7 to drive the third scraper 8 to gather the impurities in the four corners of the recycling box 1, thereby improving the cleaning effect of impurities.
