[0001] This utility model relates to the field of water purification equipment technology, specifically to a sludge discharge structure and its integrated ultrafiltration membrane water purification equipment. Background Technology

[0002] Ultrafiltration membrane water purification equipment is a highly efficient water treatment technology that uses the principle of physical sieving to remove suspended solids, bacteria, colloids and macromolecular organic matter from water. It is widely used in drinking water purification, industrial water treatment and wastewater reuse.

[0003] For example, the integrated water purification ultrafiltration membrane device with Chinese patent publication number CN219079296U includes a box, a bottom plate, and a collection box. The bottom plate is installed on the back of the box, and the collection box is installed on one side of the outer wall of the box. A membrane purification mechanism is installed on the top of the bottom plate. A straight pipe is installed through the rear wall of the box. An annular sleeve is installed on the outer surface of the straight pipe. An inclined interception plate is installed on the front of the annular sleeve. A hanging rod is installed on the top of the inclined interception plate, and the top wall of the recess of the hanging rod is in contact with the top of the box.

[0004] Existing ultrafiltration membrane water purification equipment suffers from slow water inflow because the filter screen in the pretreatment equipment is the first filtration process and a large amount of mud or other impurities adhere to it. Therefore, an improved device is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a sludge discharge structure and its integrated ultrafiltration membrane water purification equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge discharge structure, comprising an alignment device and a sealing device, wherein the sealing device is slidably inserted into the bottom end of the alignment device, the alignment device comprising a filter screen, a high-pressure nozzle, a discharge chamber, a bracket, an accumulation chamber, a hydraulic cylinder, a first rack, a gear, and a collar, the discharge chamber being fixedly installed at the top rear end of the accumulation chamber, the collar being fixedly installed at both front ends of the accumulation chamber, the hydraulic cylinder being fixedly installed at both ends of the accumulation chamber and located behind the collar, the bracket being fixedly installed between the two hydraulic cylinders, the first rack being symmetrically fixedly installed at the front end of the bracket, the gear being rotatably installed at the top ends of the accumulation chamber and located in front of the hydraulic cylinder, the filter screen being fixedly installed at the bottom end of the bracket, and the high-pressure nozzle being fixedly installed at the top front end of the accumulation chamber.

[0007] Preferably, the sealing device includes a second rack, a sealing ring, and a sealing base plate. The second rack is fixedly installed at both ends of the sealing base plate, and the sealing ring is fixedly installed on the top outer ring of the sealing base plate.

[0008] Preferably, the second rack meshes with the front end of the gear through the collar, and the first rack meshes with the rear end of the gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When in use, this device uses a hydraulic cylinder to lift the entire filter screen upwards. Simultaneously, when the high-pressure nozzle is opened, the sludge adhering to the filter screen is blown into the discharge chamber, preventing a large amount of sludge and impurities from accumulating on the filter screen. Furthermore, as the filter screen moves upwards, the first rack can also drive the second rack to move downwards, thereby separating the sealed bottom plate from the bottom of the accumulation chamber, making it easy for the user to remove the sludge accumulated on the sealed bottom plate, thus completing the work of cleaning the sludge from the filter screen and the sealed bottom plate.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 The present invention provides an embodiment of a sludge discharge structure, comprising an alignment device 1 and a sealing device 2. The sealing device 2 is slidably inserted into the bottom end of the alignment device 1. The alignment device 1 includes a filter screen 4, a high-pressure nozzle 5, a discharge chamber 6, a bracket 7, an accumulation chamber 8, a hydraulic cylinder 9, a first rack 10, a gear 11, and a collar 12. The discharge chamber 6 is fixedly installed at the top rear end of the accumulation chamber 8. The collar 12 is fixedly installed at the front ends of the accumulation chamber 8. The hydraulic cylinder 9 is fixedly installed at both ends of the accumulation chamber 8 and is located behind the collar 12. The bracket 7 is fixedly installed between the two hydraulic cylinders 9. The first rack 10 is symmetrically fixedly installed at the front end of the bracket 7. The gear 11 is rotatably installed at the top ends of the accumulation chamber 8 and is located in front of the hydraulic cylinder 9. The filter screen 4 is fixedly installed at the bottom end of the bracket 7. The high-pressure nozzle 5 is fixedly installed at the top front end of the accumulation chamber 8.

[0021] The sealing device 2 includes a second rack 13, a sealing ring 14, and a sealing base plate 15. The second rack 13 is fixedly installed at both ends of the sealing base plate 15 in front of it, and the sealing ring 14 is fixedly installed on the top outer ring of the sealing base plate 15. The lower part of the second rack 13 is slidably inserted into the inside of the collar 12, so that the second rack 13 can move up and down in a straight line.

[0022] The second rack 13 passes through the collar 12 and meshes with the front end of the gear 11. The first rack 10 meshes with the rear end of the gear 11. When the first rack 10 moves downward, it can drive the second rack 13 to move upward through the gear 11.

[0023] The high-pressure nozzle 5 is horizontally aligned with the discharge chamber 6, which facilitates the entry of impurities into the interior of the discharge chamber 6.

[0024] The filter screen 4 is located between the discharge chamber 6 and the high-pressure nozzle 5, which can accurately spray impurities into the interior of the discharge chamber 6.

[0025] An integrated ultrafiltration membrane water purification device includes a support device 3, which includes a connecting pipe 16 and a water purification device 17. The connecting pipe 16 is symmetrically and fixedly installed at the top of the rear end of the water purification device 17.

[0026] Working principle: During use, the accumulation chamber 8 is connected to the water purification device 17 via the connecting pipe 16, allowing water from the accumulation chamber 8 to flow into the water purification device 17. Simultaneously, the filter screen 4 isolates and intercepts larger impurities and dirt from the water. Later, when there are too many impurities on the surface of the filter screen 4, the water in the accumulation chamber 8 is drained. Then, the high-pressure nozzle 5 is connected to an external high-pressure air valve. At the same time, the hydraulic cylinder 9 is activated, causing the support 7 and filter screen 4 to move upwards. When the filter screen 4 is aligned with the high-pressure nozzle 5... The high-pressure gas ejected from the high-pressure nozzle 5 can expel impurities and dirt adhering to the inside of the filter screen 4. Simultaneously, the discharge chamber 6 is horizontally aligned with the high-pressure nozzle 5, allowing the fallen dirt and impurities to enter the discharge chamber 6. A discharge hole is provided at the bottom of the discharge chamber 6, away from the high-pressure nozzle 5, allowing the dirt and impurities to flow outwards, preventing excessive accumulation of impurities and dirt inside the discharge chamber 6. The hydraulic cylinder 9 continuously drives the filter screen 4 upwards, enabling the high-pressure nozzle 5 to remove dirt and impurities from different areas of the filter screen 4. During the cleaning process, as the support 7 moves upward, it also drives the hydraulic cylinder 9 to move upward along the surface of the gear 11. This causes the gear 11 to drive the second rack 13 downward, separating the closed base plate 15 from the bottom of the accumulation cavity 8. This creates a gap between the closed base plate 15 and the bottom of the accumulation cavity 8, facilitating cleaning of the surface of the closed base plate 15 and preventing the accumulation of impurities and dirt. After cleaning, the hydraulic cylinder 9 can be reopened, driving the first... When the rack 10 moves downward, the second rack 13 can drive the closed base plate 15 to move upward until the closed base plate 15 moves upward and fits against the bottom end of the accumulation cavity 8. At this point, the sealing ring 14 can fit tightly against the accumulation cavity 8, preventing leakage at the junction of the accumulation cavity 8 and the closed base plate 15. Furthermore, when the first rack 10 moves downward, the bracket 7 can drive the filter screen 4 to move downward, so that the bottom end of the filter screen 4 can move to fit against the top surface of the closed base plate 15. Thus, the filter screen 4 can perform filtration again inside the accumulation cavity 8.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
